zte obsidian 820 bootloader locked
zte obsidian 820 bootloader locked
(02-12-2019, 03:06 AM)mynewandroidproject ok so i wanted to know if i can access fastboot or somehow install twrp for this device. i tried using adb to reboot bootloader it just reboots the phone i flashed the stock rom with SP_Flash_Tool_v5.1720
ZTE_Obsidian_Z820_MT6735M_MetroPCS_V1.0_(by_ztefirmware.com) and it still wont let me get to bootloader and when i go to recovery and reboot bootloader from there it just restarts phone. is there any other stock firmware i can flash for this device to get to fastboot or be able to flash twrp recovery? Thanks. also flashing other stock firmware does not work and didnt work for this stock rom without the DA agent- agent.bin and the auth file. all the other stock firmware doesnt have the download agent or auth files. for this chip MT6735M. any work arounds would be helpful been working on this for a week now same results.
PS was able to root with dr.fone root windows program. even though whem i flash twrp it says your phone has been locked due to unauthorized firmware by T Mobile. even though i flashed the metro stock above t mobile owns metro
(02-12-2019, 07:54 PM)mynewandroidproject i thought we could create a twrp recovery with programs made from the stock recovery and then flash it with sp tools. i tried this with a twrp downloaded image and ones made from a twrp recovery img maker everytime i flash even when it say it was successful gets the phone recovery locked before bootup. i knew this was pretty much impossible. if there was no bootloader blocking it would boot to twrp after flashing with an apk app or spflash tools?
