Hi there, I'd love to help but you did not specify what version of Android you were running prior to getting a bricked device. However a general method would by flashing the stock ROM of the phone via Odin(I'm assuming its a Samsung device). Search for "unlock bricked Samsung SCH-1535" using the search tool. As for the marshmallow UI, this can only be achieved if you've re rooted your device and unlocked your bootloader in other to be able to flash ROMs with marshmallow UI. Alternately you'll have to edit the build.prop file located in the /system folder in the root directory of the device in question. This procedure also will require a rooted device. You can search around for forums that describe how this can be done on your specific device. Goodluck mate:fingers-crossed::fingers-crossed::fingers-crossed:

Hello,
There is no way to turn on oem unlock without turning on the device.
However you may restore back to the latest stock firmware. Please read about it here

[Completed] Will someone actually help with this

Okay so, My friend has a samsung galaxy s5 neo and he gave it to his daughter who is quite young. She set up her own gmail etc on it and he later had to factory reset the phone.
Upon starting it up, he obviously ran into the "please log in with the origional gmail account to verify identity." the only problem is his child cant remember the details at all.
So, he has handed his phone to me to fix as i have a bit of experience with this sort of stuff however I have a couple of problems.
First and foremost usb debugging and oem unlock allowed are not ticked whatsoever and because i cant access the phone i cant get them on. I'm pretty stumped on what to do now, i've tried several things
like flashing different stock roms on via odin etc...
i've tried getting different apks to open when i put in he usb, i have tried to disconnect my internet whenever the "just a sec" part comes up.
The only thing i can think of now would be to get a custom recovery on and flash a custom rom. But because i don't have the oem thing and debugging on odin wont flash twrp because i get the frp lock issue.
If anybody can offer me any advice on things you think i can do to help me please do, i appreciate it a lot.​

*HELP* Meizu M6 Note Bypass/Reset

Hello guys. I know there are many threads about unlocking or resetting out there but they didn't help me at all. My teacher bought a Meizu M6 Note and somehow he forgot his password. I told him I will try to unlock it but after 3 days of trying many ways I can't do sh!t.
The phone is locked with password, no USB Debugging enabled, Stock ROM, stock Recovery and locked Bootloader. I tried many times with QFIL but I always get an error from "sahara loader" or it says "... Failed to locate the file..."
If you can help me, thank you. If you can't it's ok but if you are here to talk ****, better leave.
