Is there a workaround for unlocking the bootloader on marshmallow or is it in any way possible to revert back to lollipop? Really want to unlock it's bootloader for flashing a rom and pushing apps like whatsapp with adb.
I want this too, but unable to find any clue.
Same problem. Anybody find a solution?

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.
Hi,
I've searched practically everywhere, but I can't find a solution for my problem. So my Xperia S device does not allow bootloader unlocking, and I was wondering if there is any other way to update android to at least 4.3? I know there is a way to root, but would that help me to update without unlocking?
Thanks for your help!
Hey all. So basically I recently purchased the H815T Australian optus model. It was initially on Lollipop but updated to MM & I need root so I can restore all my data from my previous device but seems I need to unlock the bootloader. Unfortunately it couldn't be done because the H815T isn't supported on the LG unlocking website. Is there another way to unlock the bootloader or rooting it? Please help guys, I really need to retrieve my data but can't do so till there is a method to root. Or would I have to downgrade to Lollipop & root? I'd immensely appreciate some assistance with this, cheers.

Thanks for your help. I really enjoy being on Marshmallow so don't really want to downgrade. Thankfully I got most of my whatsapp messages through google drive backup & most of the other apps did have some form of cloud storage. I'm gonna stick to MM till a rooting method does eventuate.
i was wondering if i unlocked the bootloader and installed a custom rom i`m not willing to change soon, can i lock the bootloader again while i have this rom?

Certainly you can if you are prepared for a bricked device later. I mean, it is not advisable to lock the bootloader if you have a custom ROM since any issues arise later, you will not be able to solve them. In addition, even if you manage to unlock the bootloader again in such a scenario, you will lose all your data including files, photos, videos etc.
If you properly sign the firmware, you don't even have to unlock the bootloader, see https://forum.xda-developers.com/oneplus-3t/how-to/guide-custom-kernels-roms-recoveries-t3572525
Hi, my carrier purchased 'Lisa' came with its ROM showing as version RKOEUBY.
My carrier isn't keeping up with updates so was wondering if I can just flash the ROM RKOEUXM without unlocking the bootloader?
I have my banking apps etc on this phone so am reluctant to unlock the bootloader unless absolutely necessary.
If anyone else has found an easy way to solve this would be grateful for your feedback.
Many thanks

Hi !
The best way is to download the zip of your European ROM from the Xiaomi site and try to install it from the update utility in your phone's settings. If that doesn't work, you'll have to unlock your bootloader, install the ROM you want with the flash utility, and choose the relock option before the install starts. Then you will be on an official Xiaomi ROM, with your bootloader locked and you will have updates from Xiaomi and no longer from your operator.

Hi,
I confirm that manually flashing the European ROM does not work (in my case at least), so I am stuck on MIUI 12.5.6 with RKOEUSF ROM.
If anyone finds a way to upgrade to the official version without unlocking the bootloader, and therefore not breaking the warranty, I would be grateful if you could share it.
Thanks
Hi !
From the moment you want to install a new ROM, you have no choice but to unlock your bootloader. You can then reblock it. Afterwards, I don't know if the warranty is impacted because you go through the official unlocking from Xiaomi.

Thanks Bill,
I've just tried flashing the zip of my ROM and the phone just quits the update after a long pause, saying that it cannot verify update.
Guess I'll have to unlock the bootloader. There's plenty of info about how to do this, but I've noticed a number of people complaining about the flash process.
When they apply the update, at the end they get an error message. The only way they get round this is with an edit of the settings of miflash.
Is this something I need to worry about?
Just been reading about these errors and it appears that they are caused by the path to the ROM file having too many characters.
Placing the ROM file in your C: folder solves this.
