Hi! Can you please let me know if you managed to return to stock. I did it few times while ago without any issues and then tried out today without luck.
My phone is unlocked and I'm not able to flash any of the stock ROMs- always ending up with errors and so far I've no idea why.
Thanks in advance!
I haven't had any issues returning to stock, and have done so each time after trying several different custom roms. I always use fastboot and use the following steps:
fastboot getvar max-sparse-size
fastboot oem fb_mode_set
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash modem NON-HLOS.bin
fastboot flash fsg fsg.mbn
fastboot erase modemst1
fastboot erase modemst2
fastboot flash bluetooth BTFM.bin
fastboot flash dsp dspso.bin
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash dtbo dtbo.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash system system.img_sparsechunk.5
fastboot flash system_b system_other.img
fastboot flash vendor vendor.img_sparsechunk.0
fastboot flash vendor vendor.img_sparsechunk.1
fastboot flash oem oem.img
fastboot flash oem_b oem_other.img
fastboot erase carrier
fastboot erase userdata
fastboot erase ddr
fastboot oem fb_mode_clear
I also flash LAKE_QPWS30.61-21-11_subsidy-DEFAULT_regulatory-XT1965-2-SUTEL-DS_CFC.xml
