Hello!
I am wondering if it would be better to lock my bootloader before updating to Oreo (when the update finally drops).
-Is having an un-locked bootloader likely to cause any unforeseen problems?
-If I lock my bootloader to apply the update, would it be possible that I will be unable to unlock it after?
Thanks,
Catalin D
You can unlock, you can lock the bootloader as often as you want
Usually you don't have to lock the bootloader to update. But i would wait anyway until the update drops and see what the community says (in terms of bugs etc)
The most important thing is if you want to update via ota, is to install the stock recovery again.

Hello Zenfone2 community,
I'm still a little bit noob in the android world, so there are a few things that are a bit abstract to me, so, let me start to explain why i'm here.
Earlier this month i rooted my device, unlock BL (unofficially) and installed Cm13, but i found a dead pixel, so i want to send i'm to warranty.
So, today i started the proccess backwards, first i reverted to stock, then i flashed blacksplashscreen, then i "uninstalled" twrp, and finally i flashed raw (with asus flash tool) then flashed recovery, droidboot and boot and adb sideload .97.
My question is, did i really relock bootloader ?? How do i test if my bootloader is unlocked ?
I already updated, (placed the zip into internal storage) and it showed that i had a new update ? Does this mean i have ota working ?

Bootloader once unlocked remains unlocked unless u decide to update to MM Beta
Unofficial bootloader unlock = will get ota updates
Official bootloader unlock = ota not allowed(u can update manually)
To check if ur bootloader is locked or not, just flash a custom recovery & boot into it, if it boots ur bootloader is unlocked if not its locked simple
Plz move ur thread to Q&A Section or ask a Mod to do it for u
so i heard that when you flash raw file , your bootloader will locked. you can try that then take your phone to asus service center to claim warranty.
Send ior to repair, they will not notice that you unlocked

If I used the official unlocker and update to MM beta will I get OTA updates?
Nope they will have ur serial no & u will be barred from getting ota
Hi guys,
It may be a silly Question for this Device , let me tell you my device specs :
Device : G4 Plus XT1643(India)
Rom : Stock (Soak NPJ75.25.2)
NON-Root and Locked Bootloader
What does the OTA.zip checks for ?
Boot image version (may b bootloader version) or recovery version ?
If its all about bootloader, then it needs to b unlocked voiding warranty.
But If its about Recovery..........Changing the Recovery to older version might help updating from Old Soak to New Official Build.
So, Did any one try flashing an older recovery thru fastboot on locked bootloader ? or Can we if its possible ?
ex: Replacing 7.0 recovery with last 6.0 build recovery. I do this for my ZenFone 5 just to avoid updating from very old builds.
Is this possible on G4 Plus ? without warranty Void issues....if possible.
p.s: NPJ93-11 gives Status 7 error on NPJ.75-2.
I tried to flash old recovery but it fails due to higher bootloader version.
Same question. Experts please advise and find a solution to get official update without unlocking the bootloader.

You don't need to unlock your bootloader to get an OTA. Its only to let you mess with your recovery and enable flashing henceforth.
However, you'll need to unlock your bootloader to flash/boot a custom recovery and subsequently flash a ROM.
But if you want an OTA, your system (including bootloader, recovery, system, etc) needs to be untouched.
If you've already upgraded to a soak test, remember - you would've overwritten your MM bootloader and recovery with an N version one (from the Soak you sideloaded)
Again, all major official updates (except small incremental one like patches maybe) look for a previous version of the OS (in our case - Stock MM)
And yes, as long you're on MM and not upgraded to N soak ever, once you unlock your BL, you can relock it using methods stated in the guide thread. Just that it voids your warranty (as the request code is generated by Lenovo/Moto, essentially letting you unlock) But if you've flashed the N Soak - you can't downgrade your bootloader just yet ( you'll get a Preflash Validation error)
Because a system update looks the stock, untouched firmware (Stock MM)
That's why you won't be able to sideload the Official N update if you're already on a soak test update - because it doesn't have the MM bootloader and recovery etc files it's looking for.

Why do you want to lock your bootloader again?
Because there is an update showing my phone npj25 93 14
I want to install it
I am confuse to install with unlocked bootloader
Here at my location there is no pc for upcomming 3 months
I don't want to take the risk
You can't lock your bootloader without a PC.
Having root and Xposed bricks your device so if you don't have them you can update with no risk por problem
As far as I understand, installing OTA updates are not affected by your bootloader lock status, they should install whether your bootloader is locked or unlocked (and I've noted in some cases OTAs may possibly re-lock your bootloader after installing). You will need a stock recovery and unmodified kernel - any modifications applied after unlocking your bootloader may cause the update to fail and/or, as Johann has mentioned, may brick your device.

Hello everyone, I stumbled upon this problem but I can't find much useful information to solve this: I rooted my Moto G4 Plus and after some time I decided to unroot and I flashed stock rom in it with unlocked bootloader. After that I'm stuck at Marshmallow and can't receive Nougat update. Everything was fine before I rooted and flashed stock rom in it with unlocked bootloader but now it doesn't seem to update. My model number is XT1642. How can I solve this problem and receive OTA updates? I also want to relock my bootloader. So to sum it all up: I want my device to be just as after I bought so to speak.
Depending on what Marshmallow ROM you flashed, it might have not been the correct version for your software channel, and thus your device won't have received an OTA (since the server is expecting a different build to the one you have).
If you wish to update to Nougat and re-lock your bootloader, you may wish to flash the June 2017 fastboot ROM, which should also re-lock your bootloader if you use the commands mentioned. Be aware that re-locking your device may wipe your data, back up and keep your data off your device until you're done.
https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138 for the June fastboot ROM. If at a later date you choose to unlock your bootloader again, do not downgrade your device to an older stock ROM from the June update.
Had a quick query on the relocking of the bootloader. So, I am planning to flash back the full stock ROM and relock the bootloader. Will this ensure that I get any future updates (OTAs) as on a new phone?
Yes, as long as you flash the correct firmware for your software channel.
That depends....
If you have flashed any Oreo ROMs, it is highly likely you will boot stock ROM to no signal. This forces you to unlock again in order to get signal.
I been trying to lock and back to stock for a while. I'm hoping official Oreo will solve the efs problems.
