According to the pictures above, the BIOS chip looks to be removable. You could buy a cheap BIOS chip flasher and fix it yourself if you can't get it to boot. Have you tried removing the CMOS battery or leaving the system running for quite awhile? The HP BIOS updates take several reboots and quite a bit of time to complete. I don't see why upgrading from 2.08 to 2.19 would cause any harm.Hi.
I don't know if anyone can help or not, i fear not.
My t620 arrived yesterday and i stupidly tried to to update the bios with the latest 02.19 bios straight from the 2.08 bios and it seems i have wiped the bios completely.
I created a recovery flash drive by downloading sp71608, bios 2.09 and used that to create a recovery flash drive.
The computer turns on but there is no activity light after i have let go of the power button, just the power button is lit.
After a minute or two the fan starts up at full speed and that's about it, it doesn't seem to respond to anything at all, flash drive or keypresses.
Great thread btw.
Cheers

the bios SPI flash chip is socketed, albeit in a shitty plastic socket with a locking top cover. If you're careful (don't break the tabs off the folding plastic top cover that holds the chip down), you can remove it and stick it in a $10 CH341A flash programmer and write out HPs bios rom directly to it: Amazon.com: SMAKN USB Programmer CH341A Series Burner Chip 24 EEPROM BIOS LCD Writer 25 SPI Flash : ElectronicsHi.

I had noticed that the bios chip seems to be removable, i haven't tried removing the battery but i have tried to clear the cmos a few times by removing the jumper and also pressing the cmos button on the board.According to the pictures above, the BIOS chip looks to be removable.

Thanks for the link, i had read somewhere that the bios chip was removeable but wouldn't have had a clue as what programmer to buy.the bios SPI flash chip is socketed, albeit in a shitty plastic socket with a locking top cover.

Yep - the same also applies for the HP tx30 and x40 thin clients - from what I remember they have Winbond 25Q64FV (8MByte) or 25Q128FV (16MByte) SOIC8 chips. I am guessing anything similar will work.the bios SPI flash chip is socketed, albeit in a shitty plastic socket with a locking top cover.

After some trial and error can confirm they are M2 screws, same as used to fasten M.2 drives.Can anyone confirm what size screws are needed for the 2.5" drive mounts? Am printing this bracket but don't know what size screw to use.
I believe I've run into the same problems Norman had, going from L40 v2.11 to 2.19, the F10 > Flash System showed up all fine, flashed, verified and reboot into nothingness. Ordered some new winbond 25Q64FVSIG chips and a programmer+soic8 200mm socket.the bios SPI flash chip is socketed, albeit in a shitty plastic socket with a locking top cover.

no but you don't need it, if you can just write the BIOS arbitrarily (which you can when you get your programmer) you can just lay down the latest to your SPI chipI believe I've run into the same problems Norman had, going from L40 v2.11 to 2.19, the F10 > Flash System showed up all fine, flashed, verified and reboot into nothingness.

Is there any chance you have a copy of the older firmwares lying around?
Thanks, I have tried to flash using CH341 programmer, even read the "dead" chip and they are the same but I still get no boot. Any other suggestions? I found an older SP95251 to the currently listed SP115305 but they both have the same .bin (2.19 revA)no but you don't need it, if you can just write the BIOS arbitrarily (which you can when you get your programmer) you can just lay down the latest to your SPI chip
