My Samsung A50s (507FN) is not booting and I want to try rooting and flashing custom rom. But when I flash TWRP with MAGISK am getting error of OEM LOCK.
Please help me unlocking the bootloader in order to flash custom rom.
Note that I am not able to turn on device.
Get back to official rom first, and enable OEM Unlock. If, there any option to unlock bootloader using volume up + volume down and insert USB cable then after warning appear on screen, press and hold volume up, to unlock bootloader.
But i dont recommend you to unlock the bootloader, because it may cause your device dead if selected file not compatible or wrong selection file.
Just back to official rom, first. (same binary version is recommended)

What does this mean? I have flashed roms while just being connected to the conputer, the rom flash utility. Is this saying that I should save it to a sd card and flash that way while in the bootloader mode (never have been in bootloader mode but read a little about how to get into it.) Thanks for any help.
Just a Noob looking for help.

naw it means put the phone in bootloader, hold volume down + power + put the stylus in at the same time..hold till you see the tri colour screen. then plug the phone into the usb (the word 'serial' will change to 'usb) and then run the RUU like normal
hope that helps mate
taking advantage of this thread, If I want to flash to latest sprint ROM can I just flash this rom if my phone is already unlocked? Flashing to latest sprint rom relock my device and change radio?
I always flash a dump version but I want to try the new from sprint.
Thanks for your answers.
We must find a way to unlock the bootloader.
How could we do?
Someone could help solve this problem?
I haven't seen anything that can do that and LG's boot-loader unlock tool only supports european G4 phones. I tried the Developer Options > Enable OEM unlock, but got a security error screen on boot when I tried flashing.
I was able to root with kingroot and install twrp which was the next best thing. You have to turn off the phone, then hold power + volume down, then release power for a second then when the lg logo appears then keep holding them both. In the factory reset menu, select (yes) perform factory reset twice and it will boot into twrp where you can flash roms and make backups.
When I installed TWRP and tried to boot into TWRP I got the "Secure booting error"..
How did you get into TWRP?
I use the H340AR

Hey all
I have the G5 Eu 850 variant and my power button has seemed to of died! (this may of happened from dropping my phone)
I want to get a warranty repair but i have the official bootloader unlock and custom recovery. How can i go about removing custom recovery and locking boot loader without the need to use the power button??? if i flash the latest kdz via lgup will that clear the recovery and make it stock without the need to power my phone up at any time? then use the fastboot oem lock command?
hope you can help!

I have had the z2 for so long but have never been able to have a custom rom on it as it has been impossible to get into recovery mode. I have flashed twrp with fastboot etc. The device is rooted and bootloader is set to yes in the service menu. I can never seem to get into twrp despite everywhere saying you hold down the power button and volume up key and wait for the led to flash. The led never comes on with this method. It only comes on when you hold volume up and plug the usb in and it goes blue to indicate bootloader mode. Can someone please help as I have been stuck on this rom since 2013. I also have never had the OEM unlock option in developer options either so have never been able to select that when following flash instructions.
Many thanks
Have the same Problem until some days. No chance to open Recovery - even i have flashed Stock Rom with EMMA and/or Flash Tool.
Inatall quick reboot and then you'll be able to reboot into recovery, had same issue.
Hi. I know this is my mistake. I just wanted to ask if there is any way for my Realme 5 RM1911 to be fixed. I used In depth test apk to unlock the bootloader. For those who doesn't know, it is necessary for Oppo and Realme Phones to use this to fully unlock bootloader to access flashing. After a failed installation of TWRP, I decided to just give up and continue using it. After a while my device is not certified on google play store. So after that I decided to go to my unlocked bootloader and lock it again using fastboot flashing lock. After that the bootloader ask me if i really want to lock it and chose yes. It booted and after that it is just displaying "The current image (boot/recovery) have been destroyed and cannot boot"
turning on and off and showing just like that. I cannot afford to fix it because Im just a student. I can't also access the stock bootloader eventhough I try pressing Power + Volume down or Volume Up. The only response is when I push power + volume up and down altogether, it is still connecting to computer but adb and fastboot doesnt work. Thank you very much for help.
