Old FW issue, cant find relevant thread

[crash1sttime]

I have a P3P that i was given to test repaired ODFM boards on, i was playing with a battery that had an error and I ran a FW upgrade and now it shows 1.1.0020+ and is asking for a firmware update, I have tried using the 1.1.0020 and it fails to flash everytime, i tried the 1.1.0030 which was released to fix an ESC issue (not an official FW but supplied to repair centres by DJI) but this also fails upgrade.

Any help would be appreciated

You might try this ; format the sd card.then type in this file name onto your sd card.
P3X_FW_DEBUG then unzip the 1.1.0020 firmware onto your sd card.
Try the update again.

Maybe you can explain how it fails . Did you check the logs ? Do you have light on gimbal ?
