I keep getting dropped to Qualcomm CrashDump Mode with "_sde_encoder_phys_cmd_handle_ppdone_timeout_sde_d ump_array" error after trying to install the rom & reboot to recovery. Have run MSM Tool with 10.3.0 already this morning, oem unlock, set up, couple test phone calls, reboot bootloader, fastboot boot twrp (mauronofrio's 3.3.1-16 Q unofficial, the correct one). I was all excited to test, but it keeps dropping to crashdump. Tried flashing rom & twrp installer zip before rebooting to recovery, doing it that way gets me to the TWRP splash screen but then still drops to crashdump with the same error.
Could this be because I have the "big storage" hardware version? A6003 (north america unlocked, not trying to use a T-Mobile version) with 8GB ram/256GB flash storage.
Update: doing "reboot bootloader" and then fastboot booting the TWRP img between rom installation and flashing gapps will switch slots and come up okay, then I wiped data and installed opengapps nano arm64 A10 beta, and was able to boot. Trying to boot into recovery still results in dropping to crashdump.
Follow this guide:
I recover Yesterday my op6 in crashdump.
This Will install 8.1.0, then update by OTA to 10.3.0
