I just got BLU G71+ (G0570WW) and from the beginning, I've had problems. It was getting super hot and would just shut off out of the blue. My cousin (who is usually good with phones and computers, etc.) said if I root it, that would fix it. I don't know how, so I gave it to him, and now it's worse than it was before.
He said he unlocked the bootloader, got a ROM for my phone (something about magic?), put it in fastboot, and ran
fastboot flash boot_a boot.img fastboot flash boot_b boot.img fastboot reboot
at which point apparently my phone started flashing on and off, on and off, and it continues to do so. Anytime I turn it on, I have to disconnect the battery.
Please tell me this can be fixed because apparently from what I have read, he voided my warranty when he unlocked the bootloader. And it doesn't respond to power + vol up nor power + vol down. Please help. He said it's a Unisoc T610, whatever that means.
Sidenote: is it normal that in my phone settings, my phone is G0570WW, but on the little sticker with the IMEI codes, it's G0571WW?
