failed bios upgrade a12 dell inspiron 5555
Machine: Inspiron 15, 5555 (AMD chip)
Similar to this post about an Inpiron 5555 the Support Assistant recommended in Win10 upgrading Bios from A08 to A12. Unfortunately, similar to this post about an Inspiron N5110 the fan started to run like crazy and the update stalled at about 60%.
The machine is dead, cannot start with power button. The only way to get anything is either:
1. Hold down Home End and push Power. Result: blinking green power light, no screen display, no beeps. After about a minute I can push the power button and the machine will turn off.
2. Or, remove battery, remove power cord, hold down Home End and insert power cord. Same as #1 after that.
(By the way, I saw online that the Home End key trick is probably Control-Escape for Inspirons with Intel chips.)
I tried to do a Bios recovery, but with no screen display, it is difficult. I copied the Bios file 5455A12.exe to a clean 4GB USB thumb/pen/jump drive and renamed the file to BIOS_IMG.rcv. Then I did #2 and got nothing.
Thanks for any help you can give.
The firmware update took total 2 hours with the fan running insanely and heat the could warm my room in winter :emotion-4:
A successful update..Had kept it plugged in and fingers off the laptop to suppress the urge to use Power key, remove battery etc etc etc.. :emotion-8:
Voila..! It worked..Yes it showed me 60% for more than 30mins :emotion-39:
Hope I didn't make you feel guilty for not waiting... Now the only option left with you is carrying it to the service center..The verified answer is no answer at all. Hold end, white flashing light, usb blinks 7 times and then rests for 20 seconds and repeats 7 times. No display. Glad it's under warranty.
Edit: support provided a crisis zip file with 2 hdr files. Put them on a fat32 usb and it took maybe 5 minutes. All is well.

The cheaper option is to find a shop that can unsolder the BIOS chip, flash it externally and re-solder it -- the more expensive one is to have the mainboard replaced.
