Hello..... please my iPhone won't come on after it went off while charging..... I have tried all I can but it is not working. I think it is because I used a different charger. Please I really need your help. How can I contact you.

@sergetognon3668 Год назад

Hello nice video. I have a question regarding the two sensors he removed between 4:50-5:00. I bought a used s21 ultra 2 weeks ago and I realist that I have awful reception. Now I opened the phone and i realist the two sensors are not in my phone and also the port on the phone where I would connect the two sensors are not there. How can that be?? I mean sometimes have reception and I also have 5G then. Is it possible that there are Models of the S21 Ultra without this to Sensors? I hope someone can help me and thanks in advance.

@FRANBROSAWEB1980 2 года назад

hi, thanks for your videos. I have inserted the skewer for the sim through the hole of the microphone. Do you think I have damaged something?

@ersbit 2 года назад

Not exactly sure you will need to test the mic to see. On a phone call, while filming front and back camera and while recording memo audio. If all these the sound comes out good you can be sure that no damage was done.

@@ersbit Hello. Thank you for your great content! I'd to ask about this topic, my main mic (the ones below) is not working. I had run diagnosis test and only this mic is not working while the upper mic is working fine. Do you think that's due to damaging mic parts and not from system bug?

@venator7889 3 года назад

Great video sir! Pleasr may I ask, wont the pre heating damage the phone's internals 🤔?

@ersbit 3 года назад

No heating won't damage you have to be time sensitive. About 2 to 3 minutes maximum straight. If you have a heat gun keeping the heat at the same location on the screen can damage it that's why you need to move around right left etc....also use the lowest setting of your heat gun (high setting can burn very easily)

@ersbit 3 года назад

All these years I had only one screen burn from heat. Internals are well protected if adequate heating is used.

@venator7889 3 года назад

@Robert-vq2np Год назад

If I'm just to fix the stuck volume button of regular s21, do I have to remove battery and some components of the phone? I dropped my phone and now it's stuck on safe mode.

@ersbit Год назад

It would be better to disconnect the battery and remove the motherboard if it is in the way. The battery does not need to be removed.

@marvicchristophergonzales589 2 года назад

Hi, may I know if the camera bump on s21 ultra is durable to protect the component of the cameras especially the lenses? Is it safe to put it down in a surface where the camera bump will hit it first?

@ersbit 2 года назад

Hello, I would suggest to add a case/tempered glass on the lenses/camera bump to protect them. It's kinda durable, but it doesn't take much to scratch them and you'll be obliged to change the whole thing

@marvicchristophergonzales589 2 года назад

@@ersbit I see, how about alunimum alloy frame instead of tempered glass, which do you prefer? Im a bit worried that theres a bad effect if put down my phone and the camera bump will hit first the surface haha. Please enlighten me that this is safe

@ersbit 2 года назад

It really depends on your preference. You just have to make sure you protect you device. I would go with glass personally because it is lighter than aluminum case.

@rashawn_g Год назад

Which part of the motherboard is the power ic. I have a dead motherboard that's good and a good motherboard that's not able to activate with service.

@ersbit Год назад

Brother I am afraid I don't have that information. Anything soldering de-soldering micro components is out of my knowledge range. You will need to search more on parts of the motherboard find the right thing de-solder it and solder on the good board (soldering skills also). Also that's if it's something that can be removed and reattach (that's very technical and out of my range sorry I could help more)

Not sure you'll need to troubleshoot the hardware. Teardown check all components for water damage then replace faulty parts. You can start by replacing the charging module.

Am not really sure it's possible you'll have to remove the frame which is highly risky and might damage the screen. Then replace the sensor embedded on the screen. It might be possible but am not really sure.

Hi, I have some problems with my s21 ultra. I have no more access to mobile signal, internet data and so on.. I can not do calls and i can not receive calls. I can't even do emergency calls. What could it be? The antenna? the antenna cable? Can you advice me on this? i can't afford to pay 300 $ to change it so i would like to do it myself. Any advice would help thanks

@ersbit Год назад

Wooo this look difficult to advice. No network, no calls this looks like antenna stuff, it can be the board with the sim card too. First and easy step would be to open the phone disconnect stuff and reconnect to make sure it's not a connection issues with flex cables. If nothing new happens you'll need to change parts one by one. Try another sim card first to see if that one work. For parts Swapping you'll need to get correct parts and change them preferably from cheapest to more expensive.

Sorry i did not remove it there. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-S_1ZvtLiDMo.html Here it is the S21 FE I removed it. There is two types.... 1- the camera is placed with thing double sided tape you heat the front of the screen just a little bit and remove the camera. 2-the camera is there with solid glue on the right and left (it is a shiny solid glue like hot stick glue) You heat the front of the device a little bit and try to remove it but you will need to prey out the camera since it is a solid glue. I show it in the S21 fe video.

@ersbit Год назад

when you prey out make sure it is not too much force because the camera can get damage if the plastic is bent or something like that.

Here in the S21 the they used normal tape not solid glue ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Nf4A-ocTj7o.html at 2:21
