How To Fix Dell Laptop's Corrupted BIOS | 100% Working !! 

YOU ROCK! Your guide rescued my bricked N5010. It's so cool folks like you with bigger brains than mine are kind enough to take the time to share what they know- please accept my sincere thanks! For anyone still stuck in Corrupt Bios Hell, here's what happened to my N5010: I upgraded the CPU from a Pentium to a Core i3 and wanted to update the Bios from A10 to the latest A15; I launched the Bios update from Windows and in the middle of the update the laptop began to reboot; I heard crackling noises come from the speakers then the screen went black and the power light stayed on; laptop was otherwise completely dead. I followed this guide and within minutes my laptop was fixed- Unplug AC adapter & remove battery; Plug in Fat32 formatted USB stick with the 2 files on it (the USB stick was obviously prepared on a working computer); Plug in the AC adapter while keeping the "End" key held down; Bios Update screen appeared, selected to update now, waited until it finished then rebooted. ALL FIXED.

This video LITERALLY just saved my bacon. I have a Vostro 3500 that just got bricked after I attempted to update the Bios. After hours of research I stumbled upon your video and it works again. The only thing I had to do was change the HDR file name to winery50. I got that tip from the dell forum and it worked like a charm. I need to write down these instructions. Thanks again.

A 6-year late comment, I know... but today, after trying to update the BIOS from an old N5010 the battery died... and I thought I´ve bricked my notebook. But fortunately I found this video after some googling and it worked like a charm! I really appreciate your help, sir! Kudos from Brazil!

I was updating BIOS on Dell N5010 from version A12 to A15 and it crashed. It was constant beeping and black screen. I followed the instruction was given in this video and my laptop came back to life. Thank You Million times. I am your lifetime fan now.

Thank you so so much for making this video. After a week of trying different methods, none worked except your approach.

was killing myself trying to do this simple fix only to realize it wouldn't work because the client's keyboard was DOA and i was using a USB keyboard. can confirm the other USB ports do not function aside from the left one, so no wonder it wasn't working. brand new keyboard installed, it worked first try. thank you!

Thank you soo much. You saved two life 1. Me 2. My laptop🙂🙂😍✌️✌️👍🏼👍🏼👌🏻

You saved my life (with Beethoven soundtrack!). You showed me a trick i was missing from other guides. Thank you so much!!! (What a shame Dell!!!)

Excellent! worked END key , Instead of using the fn+ESC keys But , I used Phoenix Tool for change FILE NAME - Dell 3300 BIOS recovery

Lifesaver, I bricked my N4030, had it back up in 10 minutes following this. Thank you!

amazing 139k people have viewed but only 782 likes. Great tutorial. Thank you. Liked and subscribed

Recently had an issue updating BIOS for a friends Dell Insprion M5030... Warranty expired and Dell wouldn't help me... just said I would have to send it in and they would look at it with a service charge and I'm sure they would've tacked on a bunch of other charges for parts that weren't actually broken too... This worked first try... you my friend are smarter than the entire Dell troubleshooting team... Cheers and thanks :)

Thanks, for me it worked but after removing the CMOS battery. Try that as well. And I put the pendrive in the left USB for your laptop it can differ so pick a USB stick with an active LED so you know if your USB port is working in this situation or not! Again thanks, it was really helpful!

Thank you very much I used your steps to solved my Dell Inspiron 5755 bios failure and its work, I fill so relieved now

Thank you very much, FINALLY worked after watching the whole RU-vid.

hi my laptop dell N5010 (Intel core i3 model 4GB RAM Model) as i have updating my BIOS in windows 10 pro it suddenly black out my screen and nothing is working. When i restarted my laptop then it not showing DELL logo only black screen and continues beep sound is coming. When i search for the beep sound all result are saying that it's a hardware/motherboard issue as skeptical i thought how this can be possible just doing BIOS update how hardware issues cause (it will arise if would flash other models bios as power constraint will be different but in my case i have flash same N5010 model bios so there should not be any power constraint ) Then i got this video and it work for me Thanks Alisha Artificial Intelligence Program thanks from INDIA . Please guys if thought its work for your laptop please provide detail comment so that anybody with same laptop model will find it easy. Thanks once again for this video it helps lot. 1:- Format USB with FAT32 2:- Rename and Copy that two file as shown in video. 3:- Plug the USB in e-SATA port (the only port on which its work for me(as my laptop has 4 usb port out of three are not get recognize only e-SATA port reconized this usb) this e-SATA port is residing on my laptop right hand side beside the LAN port. 4:- Remove battery and first press END key then plug the power cord and switch on the power . 5:- with in 5 sec it will show the DELL logo then release the END key. (This processes does not take long time as no one mention how much time it takes to show the screen. If all the people who really think this works them please share the time which required to see the dell logo. 6:- Then select flash bios it will take hardly 30 sec to complete bios flash process the press any to restart the laptop.

Thank you so much. This worked great on my N5010 dell. Dell support wanted me to just trash it and buy a new one.

Thanks! Your tutorial was very effective and helpful with an old N4030. Regards

Thx you ! Another one back to life.. It was the last try before the junk and it worked !

N5010 is alive again. Thank you.

Muito obrigada! Funcionou aqui no Dell N4030, pensei que ia ter que regravar a bios, mas felizmente não precisei pois esse processo deu certo. Muito obrigada mesmo! ❤

Hi sir I have dell latitude e6430 I try to flash downgrade My bios version A24 to A13 After this process my display is not show What can i do Plz suggest me

I have a Dell Latitude PP01L that my dad gave me because its bios is corrupt. This tutorial looks very easy. As soon as I get the charger for my pc, I will try this. It is made for Windows 98, and my dad was just gonna trash the pc, but I challenge myself to getting it working again. If I get it to work, I am going to use it for portable playing old games such as Wolfenstein 3D, Doom, Duke Nukem 3D, and Mechwarrior 2 31st Century Combat.

Doesn't work like this on a Dell Latitude E5570. It uses CTRL-ESC combination and the downloaded file can only be run on a working computer, not in recovery mode...

May I know if the file name is Alienware_15R2_17R3_1.11.0, so what should I rename it? Is it ALIENWARE_15R2_17R3? Or ALIENWARE_15R2?

You saved my money. Thanks Man really appreciate.

Hello, My dell N5010 shutdown in bios update process, i remember that the last part of bios was delete and the update was writing and Windows Say low Battery and shutdown, so, now just turn on and have blank screen (no backlight turn on) and sounds BEEPS. Yours laptops reacts like my laptops?

Worked on my N5010 perfectly, thank you!

thank bro worked for me, dell inspiron N4030, problem was shut down while bios update, not starting, black screen with single beep, thankyou so much bro

I have a Latitude E6400. i was very happy with him. After i install Win10 pro with all updates the machine runs well. a few days ago i updatet my bios to A27 in windows. I got a error that it could not flash. After i shut down my notebook it doesn´t start up. the LED and the fan shortly works and then nothing else. I make step by step by looking this video, but it will be always the same. Didn´t it work with my Latitude E6400?

you are really genius thank you very much

when using a the comands with CMD run as adminstrator, in the TEMP folder the hdr and sys fuiles are not being created? why is that?

Does this method work with a optiplex 5070 sff? I got the 2x orange and 5x white led blink and it means corrupted bios and now it won’t do anything than just blinking this code.. may it work or not?

You saved my life! Thanks a bunch!

Thing is I can’t download it it’s stuck in startup saying bios auto recovery failed

Parabens amigo me ajudou bastatnte aqui com um DELL N4030. Obrigado!!!

YOUR THE BEST EVERYTING WORKED FINE EXACTLY LIKE U SHOWED... YES :) my N5010 alive :) thx very much !!!

Thank you very much my friend, you saved another notebook!

Excellent!, It worked for my Dell N5010. Thank You :)

Perfect! Better then Dell Professionals!

your video saved me from a lot of trouble

I kept getting progress "not started". After many hours I can tell you all that I was holding END for too long. As soon as theDell logo appears release the key. too long and it never starts. Worked great on my M5010 on old and new bios' plus works on all 3 usb ports. (Some mystic had suggested to use the port next to the power socket but I proved that was rubbish).

Thanks a lot man... Another N5010 is alive!!! No support from DELL!!!

Thank you very much! Successful here in my Inspiron n4030. God bless you!

Thank you very much, during bios update from windows 10 a low battery message appeared (it was at 100%) and, halfway through the update, it turned off. Thanks for your guidance. Inspiron 15 n5010 resurrected, the usb stick has been connected in the rear left USB port. In the other USB the procedure does not work. Mission accomplished!

He tenido el problema con el mismo ordenador que has usado. Me sirvió y lo he podido reparara ¡ MUCHAS GRACIAS !

You saved my neck man!!! Thank you!!!!

Could you help me to recovery bios of dell Vostro 14 5480? I have tried all ways according to your instruction but my laptop could not go into bios screen.

Thankyou very much sir you make real video my laptop is ready

Worked perfectly. Thanks!

Bro bios corrupt hone se bios me jo product key hota hai vo delete ho jata hai kya

When i am update bios in my dell laptop i will turn off with out complete so then my laptop turn on but no display

Worked on my N5010. Thank you!

Why the renaming and capital letters of the files? No dos commands are case sensitive, although there are switches for commands that are. Might be nice to let the newbies know they don't have to rename and don't have to capitalize because if they're reading all of this and are gonna go for it, might as well keep it as simple as possible for them .

Thank you so much. God bless you.

This worked for me ...dell M5010(not a typo)...however...I had to use Rufus which is free.. to convert 32gb flash drive to fat32 bootable...and only hdr file...rom file confused install so deleted....also...since a12 bios file bricked it...had to find earlier version...a08 worked!!! Searched Google for dell bios a11, a10, a09....tried all...good luck....and thx

The reason why I'd like to reset the bios is I replaced the ssd in my Dell latitude 5580 and upon upgrading it from windows 7 to windows 10pro the backlit keyboard stopped working, I went into the bios to see if it was enabled and the option isn't even there, everything works fine but the keyboard backlit feature? Any suggestions? I'm at my wits end.

Awsome update... Great work guys...😎

Is my system unfixable? It says BIOS corruption has been detected and auto recovery is triggered. Power status: inadequate.

How to get writehdrfile And writeromfile

I have a Dell inspiron 5520 laptop that has been upgraded to Windows 10 .. the BIOS version preinstalled before the OS upgrade was A7 now it shows A10. However , recently I changed the CMOS battery and the BIOS set up seems corrupted. F2 button stroke not taking me to the BIOS set up as it did before. It takes ages now. Also the battery and the RAM is not getting recognized. Any fix ?

meu n4030 ao atualizar a bios desligou no meio do processo. agora ao tentar ligar, fica tela preta e 7 beeps. tentei realizar o processo aqui descrito mas infelizmente nao deu certo.

Thank you very much, tio! Greetings from Brazil huehue br

I tried a remote bios update from A08 to A15 over TeamViewer (stupid I know), and thinking the N5010 would be fine, but it bricked. The power button does nothing. No LEDs, dead. I tried this method using an 8GB FAT32 flash drive. Still nothing. Suggestions?

Thanks man, You saved me. Thanks a bunch. Thank you thank you.

Hello im a bit confused do i need to download N5010A15.EXE or it should be my laptop bios version ?

didn't work on my latitude e6530... please tell me what to do!!!!

HELP I have tried what you said to do and when I type the command Writehdrfile and Writeromfile I get the following " is not recognized as an internal or external command, operable program or batch file." Please help me. Thank you.

I updated bios on my Dell N5110. Now my laptop takes more than 3 minutes to boot. Before it used to boot in less than 50 seconds. Any solution?

Man, you saved my life! thanks forever!

not working on my N4030. im using a 16g pendrive and the laptop keeps beeping until shutdowns.

Apparently this fix only works if the extraction is performed on a Dell machine. Otherwise it will not work

This is BS. It does not create any files. no hdr file, no rom file. Tries it in 3 different dirs, and as admin. Does nothing.

Thank you so much for your help ... I can't explain you how much I thank full to you

Will this method also work on DELL XPS 15 L502X (2011 model) ? I have black screen issue (not even the Dell logo appears on boot & the screen is completely black but fan , all leds & keyboard backlight is working). After done all troubleshooting steps, i am sure that it's Bios get corrupted. I want to re-flash the BIOS but can't access the BIOS due to blank screen issue. Can you please help me for my Dell model. Through cmd, after extracting the .hdr & .rom files from downloaded bios file (version A12 June 2020), what rename should I do to these extracted files for my particular Dell model (XPS 15 L502x)? [Actually, I read in some other articals that we have to rename these extracted .rom & .hdr files. For eg. in case of Dell Vostro 3700, we have to rename these files to winery70 .hdr & winrey70 .rom (but it's so different from it's actual model number). So what about other Dell models, how can we find what is correct rename ? ]

thank you man, worked like a charm.
