LG v50 ThinQ 5G Teardown Disassembly Repair Video 

Because that's as far as you need to be shown to replace your screen. You'r best bet is to find a screen assembly that comes pre-attached to the midframe so at that point you can put your board and such in and reverse the process. However if you want to replace the screen alone, then all you need to do at the end of the disassembly shown, is just heat and pry off the broken screen, I mean its pretty self explanatory. Then you apply new adhesive and put the new screen on the frame and reverse the process. If you find that difficult to do, then your better off taking it somewhere that is experienced to do it. A lot of people always think these phones are like phones back in the day that you can just replace the glass, no you can't. People need to get that idea out of their heads. Screens now a days are made so thin that they are fused to the glass to give it extra support if not for other reasons but glass alone is not replaceable. Yes they sell glass parts online for cheap but its only meant for factories or people who have the machines that can defuse the glass off the screen and apply a new one. Without special machines, tools, and experience its impossible to be done. You have a 95% chance of breaking the screen trying to pry the glass off it, yet alone even be able to peel the glue off the screen to apply new adhesive to fuse back on a new glass. Plus you need a dust proof environment. I will pin this comment so others can see because I get asked all the time why people cant just order the glass and replace that because its so much cheaper. :) Hope this info helps answer your question.

@@PBKreviews Thank you so much for that explanation. Your instructional video is very helpful.

@@epacrisimp You're welcome :)

@@PBKreviews Thanks and I agree! Very nice demo. One issue is that the device you've shown is a Sprint device. The Verizon version uses different antenna's and there are not slots in the Sprint version for the Verizon antenna - in fact, they are filled with plastic. I think you can use a Verizon version for Sprint as there is a slot in the Verizon version for the Sprint antenna.

@@daustonian9331 Oh i see, ya different carrier versions sometimes tend to me slightly different

You're welcome!

Thank you!

Awesome! Glad it helped :)

Nice, yea as long as your happy with what you want and it meets your needs that's all that is important.

Thanks! I appreciate it :)

Thanks, glad it was of help :)

You're welcome, glad it was helpful :)

You're welcome!

you're welcome

You're welcome! You can also find original parts for this phone on mobiledefenders.com if needed. :)

Hi, yes you are correct. You don't need to remove all the other stuff, but it just makes it easier so you have more room to work with to pry the battery off. So if you put the replacement battery and you don't use to much adhesive to hold it down, you should be able to remove it easier if you have to replace it again.

If LG creates a phone with removable battery, I'd pay 1500 USD for it. Definitely.

Current batteries last just as long tbh... I did the same thing before. Doesn't compare to the modern tech

how the v20 has like a 4000 mah

Li-ion battery are dangerous. Theres a reason you cant remove it by yourself.

Not sure exactly where it is, it's possible its located under the shields of the main board.

There is a secondary microphone on the top left of the board you can see @2:27 in the video (its a gold or rectangular piece on the board) and the primary microphone you can see @3:38 in the video its to the side of the charger port same gold square or rectangular piece.

Hi thank you. I am not sure exactly where its located.

👍

Yup would definitely help.

Please tell me what do you mean by " gsme " ?

You're welcome

It would probably need thermal paste between the processor and thermal pad, but not between the copper and thermal pad. And its possible the copper heat pipe is aftermarket on the replacement you got and not as thick or efficient as your original. You can always try to gently pry off your original without damaging it and use that on the new frame.

@@PBKreviews can i just remove the thermal pad, and apply thermal paste betwen cpu and vapor chamber? like on razer phone?

Thanks. The flex cable to the right of the front facing cameras @7:42 in the video is the flex cable for the proximity sensor which is routed through the frame and screen so removing it would require prying the screen off as well.

lol, I'm not too sure. It might be possible to put the v40 board in the v50 housing with the v50 vapor chamber but wouldn't know for sure unless I tried. Don't have a v40 at the moment to test that out with but even though they look very similar internally, there is slight size differences which might not work so yep not sure.

@@PBKreviews it looks like the rear glass is differently curved compared to v40, more like 4 side bending in g8. Hope it's just thickness difference between both

@@harysviewty dude you are so gay. Just sell your g8 and buy the v50 when it comes out. Should be out in a couple months

search for bl-t42 battery on ebay

@@PBKreviews thank you I found it

@@monetcannon170 you're welcome

Hi, could be the battery or could be a worn out thermal pad which transfers the heat from the processor to the copper plate or just apps running in the background of your phone. Can also be a phone that had water damage etc.

Thanks. It might have similarities but I don't think it would be identical as far as the teardown process goes.

yup indeed :)

Its not really permanent, its just a strong adhesive and does not have a user removable battery tab to pull off. Doesn't mean the G8 battery and V50 battery can't be removed and replaced. I removed the G8 battery in my teardown of the LG G8 and same with the V50. Yes they didn't use the easier pull straps for the adhesive on both phones and the adhesive is stronger but it is removable you just need to carefully pry it off with non metal tools. Also yes its best to remove the main board and such so you have access to the openings around the battery to insert pry tools and work on removing the batteries. Always remember take your time so you don't bend and damage the battery causing a short etc. But one good thing with these adhesives are they are reusable so you don't need to re-apply new adhesive for a new battery you can just use the same one. Hope this helps.

:) I try to get them as soon as possible so people will see the repair-ability and build quality before they decide on purchasing the phones.

PBKreviews you're amazing :)

Thanks!

Some regions have the 2 camera versions compared to the 3 camera version of the LG V50

Hi, here is a link to one: www.fixez.com/lg-v50-thinq-5g-pre-cut-back-battery-cover-adhesive?gclid=CjwKCAiAqt-dBhBcEiwATw-ggAHI9MgAHc3CZA1W2BKA7VoZZOjNUQVM8qm7jwwt8KFNlD3xjlLbVhoC-dEQAvD_BwE

@@PBKreviews Hello me again, I hope you can help me with this, I have been repairing the screen of my LGv50 for a long time and what I did was move all the pieces (motherboard, battery, cameras, absolutely everything) to a new screen with a new casing, everything is fine so far, after sealing it and when using it it began to occur to me that it turns off when it has between 40 and 20 percent battery, it turns off as if it had 0%, do you think it is a battery calibration error or that the battery is it damaged?

Thanks! here is a link to the original replacement pre cut adhesive: www.mobiledefenders.com/adhesive-back-cover-for-lg-v50-genuine-oem.html

It makes it easier to remove the battery by removing the parts around it to give you more room and not damage other parts. You can also use isopropyl alcohol to get some around the battery and let it sit for a minute so it eats away at the adhesive and makes it easier to pry off.

Aliexpress

Hi, it's not too easy to find, usually comes with screen assembly replacements. Here is a link to one but I have never bought from this website so I can't vouch for it: www.tokopedia.com/multhiez/lg-v50-heatpipe-vacumchamber? . Worst case scenario, you can try using some copper tape/film and apply it to the frame where the heatpipe should be, and add thermal paste on top of it (non conductive thermal paste) so you can have a means of heat transfer.

After taking the phone apart as shown in the video, all you need to do is heat up the screen to loosen up the adhesive holding it down to the frame and pry it off the frame. Then apply new adhesive and apply the new screen and re assemble the phone.

Thanks! If there are cracks or breaks, there is a good chance it won't be water resistant any longer.

You have to remove the back plate and the top plastic cover over the motherboard to disconnect the battery cable. At that point you can apply heat with a hair dryer or heat gun to the front of the phone where the screen is to gradually heat up the adhesive underneath the battery to loosen it up. Then you can pry the battery off. It's easier if you remove the main board as well since it gives you more room to work with but its not required.

@@PBKreviews Thank you so much!!

Thanks. What help do you need? you can get some parts for it here: www.mobiledefenders.com/catalogsearch/result/?cat=0&q=lg+v50

If I'm not mistaken, that's where one of the 5G mmWave antenna would go if the phone for example was for Verizon since Verizon's 5G network uses mmWave technology. But phones which are from different networks or regions which don't use 5G mmWave but instead only 5G sub-6 Ghz etc. then those have those plastic inserts in those slots usually.

@@PBKreviews Thanks a lot. I am just using 4G LTE so hopefully a different version of this antenna will do just fine...

Yeah, I have the same question. They looks similar. Is connector the same? Can I replace my camera module in V50 with V40 component?

Ya you should be able to add another thermal pad

@@PBKreviews thanks! Its good to know that this phone is still salvageable :D

@@PBKreviews or some thermal paste?

​@@PBKreviews do you have link where to buy thermal link/heatpipe v50s?

You're welcome

If you are replacing just the screen and not the midframe as one piece, then you would be fine. But if you replacing a midframe with screen combo, you would probably have to pry off the vapor chamber carefully and place it on the new midframe assembly if it already does not include one.

@@PBKreviews what do you think sir , is the vapor chamber cooling system used in the V50 more effective than the heat pipe system used in the G8 and the G8X, in terms of good temperature maintain ?

@@oussama7084 I'm not 100% certain but I would lean toward vapor chamber being a better option due to the fact it has more surface area to attract and transfer heat compared to a heat pipe.

Usually I look for precut adhesive that comes with replacement backs to ensure a good seal. If available usually can be found on ebay amazon etc. But if not you can 300lse or smartphone red tape or other adhesives for smartphones and cut strips and apply to the frame of the phone.

Also, will the phone lose its water and dust resistance rating after being disassembled?

Once you have access to the battery cable to disconnect it, you can remove the battery. Also yes you will lose water resistance unless you use the original pre cut adhesive to re assemble the back cover/plate or get a replacement back cover that has the adhesive pre installed.

@@PBKreviews well noted...thank you for your reply 🙏🏼❤️

This video was made years ago so I don't have the phone anymore :)

Its a matter of preference, but a lot of people would probably go for the one plus

You're welcome :)

@@PBKreviews i finished replacing the usb port bout an hour ago. Everything went good and thats working, but now my Verizon signal keeps cutting on and off. Did I mess something up or somethin maybe disconnected?

@@unblindswordzman96 make sure the board is seated in properly since there are gold contact points which touch points on the frame for signal. Also make sure all thr cables are connected properly and not loose.

@@PBKreviews i believe it may be that cable that run off the usb port. Its so damn hard to press down on it and get it to stay down. It keeps popping back up

@@unblindswordzman96 hmm shouldnt be that difficult, unless some of the pins got bent or connector is damaged. Should just click in place.

Yes you would need to apply new pre cut adhesive to re apply the back plate/cover. Here is a link for the original pre cut adhesive for the phone: www.mobiledefenders.com/adhesive-back-cover-for-lg-v50-genuine-oem.html

not sure, I haven't ever used that.

The phone standard comes with a copper vapor chamber/heat pipe unless you replaced the screen and did not transfer it over from the previous frame. If it doesn't have it, then yea that would be the cause of the over heating. If it does, its possible your thermal pad has worn out or needs replacing. You can use another thermal pad of the same thickness or use thermal paste.

If you use an original pre cut adhesive made for the phone to re attach the back plate, it should retain the water resistance. But if you cut your own adhesive strips to use, then it wont retain the water resistance.

You can get the original oem ones here www.mobiledefenders.com/lg-repair-parts/v-series/v50-thinq.html

Hmm not sure. Sometimes different region versions can vary, but it might also be possible the screen was replaced if the phone you are using was 2nd hand, and they never replaced the heat pipe.

The V50 battery is slightly larger and also the connector is located further away than the v40 connector. V50 battery connector is more in the middle section but the v40 is more toward the left corner of the battery so it would not even reach to make the connection.

@@PBKreviews thanks for the reply. Do you think the v50 battery would fit in the battery spot? If it wouldn't fit, then its a no go.

It's possible, different regions have slight variations sometimes. Some have the light up 5G logo some don't.

@@PBKreviews it turns out the phone is an LG K51 ! Thanks

yes they are held on with adhesive

If you replaced that part, it requires a factory reset on the phone to calibrate and work. Make sure to backup your data before a factory reset.

@@PBKreviews I actually got it working not long after. Apparently my back case wasn't making great contact with the pins. I bought a new back case just so I could seal it up again and (maybe) have it be waterproof. No need to factory reset here. Thanks for the video! Couldn't have done it without you :)

You're saying after you changed the battery, the touch is not working? Check the screen cable to make sure it is properly connected and make sure it has not been damaged.

@@PBKreviews Thank you for your answer teacher, what number is the screen cable here at ko.ifixit.com/Guide/LG+G8+ThinQ+Screen+Replacement/146643?lang=en? The other teacher told me to try number 12 again when I mentioned the symptoms Is that right?

you need to remove the motherboard (it isn't necessary to remove the battery or other components that are pasted to the frame) since the electric contact point of the buttons is below the motherboard .

@@MiloTheFirst1 thanks

Hi, you need to just move it around and evenly heat up the back. So try not to hold it on one spot for a long period of time. You can also use a hair dryer which will be safer in terms of damaging any parts.

@@PBKreviews once i completely removed the battery door can i still use the installed one or should i replace those adhesive seals too?

It was the Korean version

Not sure, I would think ebay or amazon since most OEM resellers don't carry LG parts as much anymore.

If you can get a back plate with the original precut adhesive then ya it should be resistant again, but if you have to cut adhesive and put it on yourself then probably not because there will be gaps etc.

@@PBKreviews it's not possible to find the exact one as my sprint variation isn't available... However I did find pre cut adhesive for the lg v50.... I think this should do

@@simplyalif Ya, the v50 adhesives should all be the same

Yes I applied heat, but just didn't show it on camera to not waste time.

Pretty much most the stuff. Back cover, top and bottom plastic covers, motherboard. Then you will have access to removing the flex cable with charger port on it.

​@@PBKreviews after replacing the charging port, I'm not getting any mobile data connection. It detects my sim but it just says "service disabled". I tried going airplane mode, restarting, network and apn resetting and nothing works. Any idea what's wrong?

processor, ram and memory are located in that area. Not sure what brand thermal pads they use.

its possible your adhesive around the backplate needs to be replaced or your camera lens cover may be cracked and lets moisture in needing replacement

Depends which cable you are referring to. There is one that goes over the speaker assembly on top and that is for the connector points on the back of the phone and there is a cable with is attached to the speaker underneath the assembly which has two gold points which need to touch the gold pins on the sub board/charger port board to get signal. So make sure its screwed down in place correctly, and that those 2 pins are not bent or damaged etc.

@@PBKreviews Okay well thank you for replying. I'll look at my phone again and I'm pretty sure its the top one over the speaker that I'm missing

@@bootswiththefur1xd361 no problem. The top one shouldn't affect the speaker working or not.

@@PBKreviews well that is good to know so again thanks

Hi, I'm not 100% sure but I would assume it would be compatible.

Not sure what speaker mount you are referring to.

@@PBKreviews I mean the flex that connects the motherboard to the rear connection pins.

@@salvananez Oh not sure, I have looked for someone else as well couldn't find it

You would need to replace that bottom charger port flex assembly which has the mic on it.

It's dual and shares with one of the sim slots.

there are many types but you can use smartphone red tape (link in description) or other strong smartphone adhesives

@@PBKreviews Awesome, thanks

Yes and yes

I'm not sure, if even the connectors and locations are the same, there may be software issues.

Might need a new screen

Not sure if the motion sensor would be what is causing it to over heat. Have you tried backing up all your data and doing a factory reset on the phone?
