Hi Victor / Bob

I was wondering if you could help, is it possible to flash the BIOS without a battery pack ( on t2x series laptops ) ? - also do your PC8394T tools require the systemboard to be powered or can the chip be read with external power applied ( like the 24rf08 tools )

Thank You

I know that is this quite annoying, indeed the phoenix flash utility checks whether the main battery is mounted or not. And is normal to do that, because a power loss can occur at any time.
An option would be to use other software to flash the code, but as far as I tested, none can flash 100% correctly the Phoenix First BIOS, not to mention that you need often to upgrade the EC firmaware as well.
Or another option is to remove the chip and do the job with a stadalone eeprom programmer, but this is not practical.

Or, insert the battery Smile

.

PC8394 tools require the board to be powered, they are made to work with on-board TPM chips.

flashing without battery is poosible,
iirc you have to extract the image and flash manually,
its a little tricky, read the methods for 600, 770 and 570
and if possible that german article with a smart 1byte hack

You do this at your own risk ! (as always in life:) so
do it only if you are fully aware what you are doing !
