Ahhhh, it was you at github. Lol. I've been watching and updated that some have been chatting about this in the development section.

i was able to extract the BIN file downloaded from DJI into the files shown in the first screenshot. I was then able to extract files from the P3X_FW_V01.08.0080_mi12.bin file and its whats in the second screenshot. From this, i was able to extract files from P3X_FW_V01.08.0080_mi12_part_rom_fw.a9s which is in the third. Thats as far as i can get. I'm not a Linux guy, this would be much easier in linux, and one of the sh files requires it.

I wonder why it's not recognizing the [17 00]? That is for the Gimbal.

hmmm very nice thankyou for trying and posting that log good job. it looks like it might have installed alot of things. can you confirm any thing to be different after trying. im not sure if theres a way to read every things version number after an upgrade or not.

m12. contains a ubifs if you have a ubuntu machine install mtd tools and you can mount it and see more. i wanted to edit init and see if i could get shell access from the gimbals usb port. it looks like they edited the line out so it wont start. this would require repacking the binaries and re-flashing. and you might loose mass storage on that usb port.

Yeh you might have more luck in trying to flash a much older FW, e.6 1.3 or something.. Maybe they were more lenient.
Or could it be that using this debug file you need use to flash backward in a sequential order i.e 1.9>1.8>1.7. and so on ?

okay, so i was able to successfully go from 1.8->1.7.its weird though, cause the gimbal showed a red light and the failed sound. But, when i turned on the phantom and brought up DJI go, i get 1.7. However, I'm also getting version mismatches .. so I dont think it reverted all of them back. I'm attempting a new install of 1.7 on top of 1.7 to see if ti resolves.

On 1.7, I also get compass errors I cannot resolve.
