Hello guys, sorry because may be this is the 50th time someone ask this question but the situation change every day. Yesterday I won from lottery and decide to go from G3 to G4. My model is European H815, I want to ask you can I root G4, change the recovery and e.t.c. without unlocking the bootloader? And also if I unlocked it is their any way to locked it again or to use my warranty? Thank you!!
well you can only root using low effort root(google it or find it here ) But to change recovery you have to unlock bootloader
No there is no way confirmed to relock your bootloader
GOOD LUCK
Thank you! If I root by this way and download Flashify and try to change recover what will happen ? Thank you!
without bootloader unlocked nothing will chnage ( recovery wont be installed ) and when you reboot your phone it will get u error (authentication error #9) as i remember and you will have to flash new firmware using lg flash tool 2014 so i dont recommend you do so
if u wanna change recovery unlock ur bootloader
you are welcome anytime
I did not get it, I hope you can light me up:
1. Doing root using low effort root means rooting without unlocking bootloader? (because I flew over the thread and did not read anything about it)
2. If I do unlock Marshmallow's bootloader, what happens when I downgrade to Lollipop via flashing proper KDZ? (I would guess that the unlocked bootlader will be overwritten!? So flashing Marshmallow again would end up in a locked bootloader, doesn't it?)
thanks
You can root lollipop without unlocking bootloader but with marshmalow you can't, you have to unlock the bootloader.
You need an unlocked bootloader for custom recovery.
Bootloader unlocking is a one way operation , you can't go back.
I am stock firmware and havent touched it. I only have unlocked bootloader of my moto g5. Can I OEM update with unlocked bootloader?.
I saw an article for locking bootloader and it said to flash the firmware again. As I am already on untouched firmware, can i directly lock my bootloader? I have bricked a device in the past and so don't want to do that again.
I am planning to sell off my Motorola G5S.
At present, the bootloader is unlocked and the phone is rooted.
Can someone tell me how to unroot the phone and lock the bootloader?
Additional Information: I used the following thread to unlock bootloader and root my phone.

Thanks in advance.
I have such problem.
xt1789-04 with TMobile. Bootloader unloccked. Was unlocked sim to use not in USA. After that i cann't flash any custom. After intaling firmware from trwp oem became locked. Also cann't donwgrade modem firmware. Also try to flash customs from adb - got anther oem_locked
You can check the Tmo carrier unlock policy. But I think the carrier can not be relocked (I've use ATT àn VRZ before). It seems the modem fw had problem (maybe its own firmware) if it had not recognized the sim card. If you have the EFS backup, you can restore it.
If you're bootloader is relock, no, the custom roms do not relock the bootloader. The unlocked bootloader can be relocked but can not be relocked as stock.
Hi my Sony Xperia xa2 say bootloader unlock no is there anyway to force software or at least root with out unlock bootloader thanks
This is not possible. In order to flash anything to the device, the bootloader must be unlocked. The whole point of the bootloader lock is to prevent flashing anything; firmware is updated via OTA.
