After doing a developer edition conversion on a M8 international phone. I'm having issues. The client stated that he gets error messages on the phone such as System has stopped responding., a This shouldn't be an issue after a factory reset. The phone was 4.4.4 and S off it's now 6.0 and S off. He cannot seem to access the bootloader screen to get to the factory reset options and i cannot run adb reboot bootloader as USB debugging is not enabled.... The device currently has a stock recovery as it was updated via a TWRP backup, and then the boot.emmc.win and the stock recovery was flashed. This allowed for it to update via the normal OTA so 3 small updates then the MM update. Any ideas to force it into bootloader mode is appreciated. Hopefully he will be able to get into the bootloader mode or enable usb debugging s i can do so. It may just be he's tired as it's 2:18 am in the U.K. and i'm in Illinois. The device will be rooted and have a systemless boot.img flashed and TWRP, SuperSU once it's done lol. I did try and run a RUU to see if it would detect it and put the device into the bootloader so i could access the factory reset option. I didn't think it would work but worth a try.
