If the phone has a removable battery, remove it for 5mins and insert and try again. If that doesn't work, try using mtkdroidtools, it should work for your mtk model. If not, please reply as soon as possible with log cat.
Hi all
I have a BLU Life Mark phone running android 5.1. I can't find any specific tutorials for the handset, so have tried some applying the tutorials from other phones made by the same manufacturer.
I'm a complete noob, using a Mac, but managed to get the phone into fastboot using USB, terminal and adb, and run the oem unlock command.
At this point, the warning screen pops up, and I am given the option to press volume up to void my warranty and unlock the bootloader, or press volume down to abort.
Pressing volume up does nothing - the button is fully functional when the phone is operating! - but pressing volume down DOES abort.
I have enabled OEM unlock and USB debugging through the developer options, but occasionally when the phone reboots, OEM unlock is disabled again!
I would really welcome any suggestions - I can't find anything online!
Thanks in anticipation.
i just need a little help here, does anyone know the button combo to get into bootloader? i tried Power + Vol down. this didnt work.
i did do a OEM unlock with delevoper mode.
thanks.
