Hello, I have an NMO_L31 (honor 5c - huawei gr5 mini) device and I have experienced a Failed (remote: image verification error) error when installing TWRP while my phone was unlocked before. have searched from a lot of technology pages to find remedies but all failed. But my God, Jehovah listened to my plea and brought me to @shashank123
, I contacted him through XDA and I got him a phone number to make friends on the telegram, he helped me out I and I have overcome the above error. I would like to explain how to overcome the error that I tried. First, I went back to emui 4.1.2 (you can see the instructions then allow OEM unlock, then I update the OTA to emui 5, allow usb debugging when the update is complete. Shift + Right click on CMD (or powershell) and enter "adb devices" to see the connected device, then enter "adb reboot bootloader" then enter "fastboot oem get-bootinfo" To check if the bootloader has been unlocked, then enter the command "fastboot oem unlock (code)" to unlock if the relock bootloader, then if the bootloader has been unlocked then the purpose of the command to factory reset. If that is the case, then go to the phone and see if factory reset is complete. Then develop and reconnect to adb, check the device connected to the "adb devices" command then go to the "adb reboot bootloader" command to get to the fastboot and then use the command "fastboot flash recovery recovery_name.img" (for example : Twrp) "Finally, if the word OKEY appears, you are successful. If you can not solve this problem, please send a message to @shashank123
in XDA and ask for his phone number to make friend through telegram and regular help message because he does not often use XDA. Thank you very much Shashank for helping me. Thanks be to my god JESU CHRIST and JEHOVAH.
