Hello everyone.
I have come here with a rather specific question. I was given a Dell Latitude 7420 laptop with a busted screen, and wanted to see if I could refurbish it into my daily driver. I wanted to experiment and see if a 2-in-1 display would work as the chassis of the laptop and 2-in-1 7420 looked identical. I threw in the display and my hypothesis was correct, however, I was greeted with a locked BIOS and since I didn't know the password, I figured I'd try to unlock it somehow. I bought one of those POGO pin probe things for my CH341A programmer so I could read and make... -
Hi everyone,
I hope someone can help me.
I have an Asus ROG Strix Scar 18 (G814JZ) laptop with a Winbond 25Q16JWNIG chip on the motherboard.
Unfortunately, I flashed the wrong file (BIOS/EC/other region – I'm honestly not sure anymore), and now the laptop is completely dead: no display, no fan spin, no reaction at all.
I have a CH341A programmer and I'm able to read and write to the chip. However, I'm not sure which software is best (AsProgrammer, NeoProgrammer, etc.) or if there's anything specific I should watch out for.

Hello.
I received a 840 G1 with completely wrong system info in BIOS.
Serial Number and everything is wrong, even the Model is wrong (written as 850 G1)
How can i reset these info?
Thank you! -
Long story short:
- dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
- gave the computer to his son a couple years later
- son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
- too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
(seems like the story was not that short)
He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8... -
hi,
i've being using this Cello tv, uk brand, C40rts, HK.T.RT2841P638 main board, for a year or more.
Last week i've found an update, 3rd party, that i though it was close to my board. Inserted on a usb stick the install.img, started the Firmware update, ended, rebooted and nothing. The led (red-green) keeps flashing, backlight is on but to response on remote.
I've retried with original fw, no success. Hooked the uart Cp2102, putty, tried to swuu command (to update from usb), it goes for a while the get "cpu reset" on laptop screen that brakes the process and halt....11-03-2024, 02:28 AM
