Good morning,
Having bought a phone LG G4 from China I doubt a bit of their ROM (we never know if they added cookies or what ..) So I decide to get started in the installation of a custom ROM. So already I notice that the phone is already rooted (while it was under blister). Well then I have to unlink the bootloader and I must restart in fastboot but nothing done I can not access the bootloader ?? I tried with the command window (adb reboot bootloader) but it restarts on the home screen .. ditto with an app boot manager, I go back every time on the home screen. How come? I do not have a bootloader or what ??
Thank you for clearing me up.
Sorry for my english

not all LG G4 can be bootloader unlocked only some european and tmobile usa one.
if you had root maybe it was on lollipop phone is bootloader locked.. in lollipop only it can be rooted using system.img rooted. and injecting.. but if you update to MM with locked bootloader it cant be done. no root nothing..
also downgrading in somephones to lower android version bricks phones they have antirollback.. not sure it it applies to all g4. mine does it tmobile.. maybe other can be downgrade. see if yours can at lest to have it rooted..

I don't have the fastboot mode, so you think it's normal? Mine is on LP but I can't update to MM (the category update is missing in settings) wich I think is due to the seller chinese, he did some strange things on the phone I think.

Hello,
Just want quick help from the experts to ensure I dont end up buying a Verizon unit > 7.1 and end up with a brick which cannot be unlocked and rooted.
So I am on the hunt for a Google branded set. Just inform please ,
1. If it is a google branded set, then can the bootloader be unlocked on it regardless of any locking/unlocking done in the past, even if it is upgraded to the current 8.1 version ROM.
2. I have been eyeing a Google branded unit for which the bootloader was unlocked, then locked again then was flashed with the Beta version of the 8.1 ROM and finally the production version of the 8.1 stock ROM. Would it still be able to unlock the bootloader.
Thanks for filling my knowledge gaps.
Yes to both of your questions.

I can't speak for the Verizon version but if you pay for the EE version to be similar unlocked the toggle to unlock bootloader in developer options stops being greyed out
Hello guys,
i need your profressinal help. First of all please excuse my bad englisch. But this forum is my last hope.
I rooted a Samsung A5 (SM-A520F) and everything was fine. But yesterday my girlfriend rebooted this phone it was FAP locked. So i googled a very long time and found a lot of solutions. But i did some misstakes. What i've done:
Phone flashed by combination firmware
Enabled USB Debugging
Flashed the stock OEM (Oreo 8.0) and it bricks on installing hidden.img. Today i now my choose was very badly, but it is happend. I flashed the Stock rom with CSC File and not the Home_CSC which bricked.
I have no possibiliies to flash another ROM... not the combination or a custom Recovery. The Debugging seams to be disabled. The OEM unlock is the same and my bootloader was overflashed by the stock rom.
I didn't know about the new FRP System and created on every mobile phone a junk google account. So i have no choice to enable FRP on the normal way.
Thank you very much
Isn't there any possibilitys to get my phone back?

Please, someone, help me

These coolicool phones always come with the wrong firmware install, the simple solution to that is to flash the correct firmware which is plain old RETAIL. Solved. That's for anyone who might have or end up with one of these phones.
As for your phone and since you're in the situation you are I'd flash VZW pie. That isn't the correct firmware for your phone, but you've got a locked BL with VZW on it now and nothing is working. Since your ultimate goal is to flash pie anyways, that's what I'd do. Maybe that will clean up your system enough to enable oem unlock. If you can get your BL unlocked, then you're half way there. Surely by now you've realized that you haven't got many if any options.

You need to elaborate. Is oem unlocking grey out? Are you signed into google services? Do you have wifi and/or radio?

You shouldn't flash firmware from other variants like att, etc. However, if you're able to flash those firmwares and not get any permission denied errors then your bootloader is unlocked, which is good. If you have NOT flashed a pie firmware, good, do NOT do it until everything is up and running and you're sorted. If you have, then you'll need to use pie firmware to fix it since once you flash a pie modem there is no going back to an oreo modem.
Run this command from bootloader/fastboot mode and post back your output.

I have a Mi 10T purchased in Italy, and therefore coming factory loaded with a "branded" firmware RJDEUHG. It should be a Windtre modded ROM, please correct me if I'm wrong.
The latest known working ROM was the miui_APOLLOEEAHGGlobal_V12.5.3.0.RJDEUHG_da9e1c75b5_11.0.
Tired of waiting for the slow updates, compared to the unbranded global rooms, I decided to de-brand the phone and upgrade to a stock RJDEUXM.
But none of the XM firmware would load from recovery, therefore I applied and successfully unlocked the bootloader.
With the bootloader unlocked I managed to successfully flash
apollo_eea_global_images_V13.0.2.0.SJDEUXM_20220329.0000.00_12.0_eea_ad6f7ce846
apollo_eea_global_images_V12.5.12.0.RJDEUXM_20220208.0000.00_11.0_eea_664a15ed19
but both got stuck in a bootloop right after flashing.
During one of the many attempts, I used the MiFlash tool and accidentally left the default Flash & Lock option, the flashing was successful and the bootloader was locked.
At the moment I'm on V13.0.2.0.SJDEUXM, and can load onto bootloader and recovery, while, as mentioned before, the system won't load and get stuck in bootloop.
If I try to unlock the bootloader once again, the MiUnlock does not recognize the phone while in fastboot mode, remaining in the "Not connected to the phone" screen.
Any help would be really appreciated.
maybe, this is the solution, seems the same issue

fastboot devices
fastboot continue
if you have some lucky, boot normally
otherwise follow all the step
