I am thinking about downgrading my fully functioning P10 (VTR-L29) running 9.1.0.253 (C635E2R1P8patch03) for Japan to Android 7 with DC-Phoenix by Method 3 so that I can read bootloader unlock code. Could you kindly tell me which firmware to use, not bricking my phone, please? Thanks!

hi gsmgeo, thanks for your comment.
i am simply trying to downgrade the firmware without region change. i am not a newbie with android phones, and i know you can downgrade a p10 to nougat using testpoint, but there are so many fail stories like losing IMEI, and there are few helps or guides. so i am kind of confused what i should follow.
i am not 100% sure if i can write UPDATE.APP of the appropriate ROM (Android 7) that i download using dc-phoenix...

Yeah, I have figured out that I need VTR-Downgrade-Board-A067-7.0.0_r1.dgtks to downgrade p10 after searching over the net.
Flashing VTR-Downgrade-Board-A067-7.0.0_r1.dgtks and then designated Android 7 update.app would do the job, right?
Thanks for your help very much.

after that, maybe you need to change to the optimal region, and this is eu (vendor c432)

Hmmm... You are giving me more questions:-)
Flashing VTR-Downgrade-Board-A067-7.0.0_r1.dgtks makes my JP P10 c432 (EU)?
Why do I need to flash this 8.0.0.386(C432) FIRMWARE? If I flash it, I cannot get the bootloader unlock code, can I?
Thanks again.
