How to get OTA Updates after unlocking the bootloader - Lenovo Zuk Z2 Pro Questions & Answers

Hello everyone!
I unlocked my device and rooted it. Then i used the AICI custom rom for a while.
Now i wanted to go back to stock ROM for having the Android 7 Update via OTA.
I locked my bootloader again and installed via QFIL the stock 2.3xxxx ROM
But now when i try to install the OTA Update the phone tells my that my phone is rooted and i am not able to get the OTA - my phone isnt rooted anymore and the bootloader is locked again.
i thought if i flash the stock rom with QFIL the bootloader is locked again, but i did it by myselfe with fastboot.
so what can i do to go back to the beginning?

Install ZUI 1.9 via QFIL and then do the OTA updates. That's what I did to re-lock my bootloader.

From what I understand you're saying you do not want to install a custom rom, just rooted stock rom?
Yes you can still recieve ota update but I think you must relock the bootloader before you install ota update
You could do that yet it would be an unbearable and unnecessary effort.
Just go with Android Revolution HD.
It is in sync with the OTA updates, nothing would look or feel different than stock. But has a better performance and battery life overall.

All right, I want root my stock rom and (Titanium Backup) and to continue to have the official update.
INFO:
Unlocking through htcdev.com will wipe your phone to factory defaults. Nothing will be wiped of you sd-card, only of your phone.
Ok, but after i have ulnocked the phone with htcdev, where find a guide for root?

After you unlock, you can use the same procedure that you do for Revolutionary, namely you install ClockworkMod Recovery and then from CWM recovery you can install the lastest version of su-3.0.xxxx.zip to root the ROM. Then you can use Titanium Backup, BusyBox, etc.

Relock the bootloader first, then ruu.

are you kidding me :/ this is the dev-ed... also i guess it doesnt need to be locked to RUU at least it is no needed for OTA updates, the requirements are just has stock recovery and unrooted phone

i got the updated by restoring a STOCK backup (no root) form CWM, then flash stock RECOVERY and then update the OTA, so relocking bootloader IS NOT NEEDED, the only thing is have all STOCK and NO ROOT
You asked about running ruu in your original post. To do that you do in fact need to relock the bootloader. Just saying.

Update for unlocked bootloader

Can we update phone's software via ota even after unlocking the boot loader and installing custom recovery
Nooooooooooooooooo
No, Not even in your dreams,
From what I've learned from my own Issue
http://forum.xda-developers.com/moto-x/moto-x-qa/totally-screwed-updating-rooted-x-4-4-4-t2896292
Never update phone's software via ota, while you are on Custom Recovery.
Patel21 is correct, you can't with a custom recovery.
You need stock recovery to take the OTA, then you can reinstall a custom recovery

Yes you can as long as you flash back to stock recovery before accepting the OTA. Once done, flash custom recovery and root if lost.

OTA will not install when you have a custom recovery on your phone. Instead you'll be stuck in a bootloop if you have tried to install an OTA with a custom recovery.
Rather than my retyping everything... Please see -> http://mark.cdmaforums.com/MotoX-OTA.html
I've flashed ota updates via custom recovery, you just have to know what you're doing. Also, the Moto boot loader won't relock as far as I know after an update. It doesn't on the Dev edition, not sure about unlocked retail or devices that have been unlocked with sunshine.

Since all unlocked devices are the same as the dev edition....the same would be true.

The only thing I want sure of was sunshine. If you unlocked via a code, then yes, all of them act the same.

I don't completely understand how Sunshine works, so I can't say for sure, however based on reading the thread, my understanding is it wont relock.
But if you unlock via mfastboot oem unlock {YourUniqueCode} your bootloader will not relock itself. This holds true for developer and non-developer alike.

XT1064 on Lollipop. How do I relock bootloader?

My bootloader is currently unlocked and I want to relock it. I have an XT1064. I've tried downgrading to 21.11.17 and following the instructions for KitKat but it never works. What can I do?
Unfortunately I have yet been successful doing this. I think it's because some parts of the firmware can't be downgraded. I keep getting pre flash failure
i did just for kicks... and was successful on XT1069.
from what I understand when this problem happens, is related to the ROM you used to do the process that is described in this thread follow these step with a ROM that is perfect and will succeed.
I did with the good xml ROM for my device and it was perfect.
try other ROM xml file... all i now here
One thing, to receive an OTA is not need to be with bootloader locked...
But you must have a untouched original ROM and Recovery installed on the device...
So no root original ROM and recovery just that.
I say this because many worry that is need to have a locked bootloader to receive OTA, and is not.
Have you tried locking after being on 5.0 firmware
I don't remember (i think was 4.4.4 to 4.4.4)... but i will try (5.0.2 to 4.4.4 and lock it) and report. OK, maybe today if not tomorrow...
In theory is the same friend of my did form 5.0.0 to 4.4.4 no problem...

Pretty sure you can only relock 4.4.4 bootloaders (motoboot.img) with the oem lock
If you have updated to a lollipop 5.0.x bootloader you cant downgrade from a 5.0 boot loader and hence cant relock it (yet?)

You can downgrade if use a ROM or a backup to update. the bootloader will remaining the same.
I dont know if you update via OTA to L if the OTA is updating the boot loader...
But yes you can downgrade from 5.0.x to 4.4.4 regards the bootloader if did not update don't see way will not re-lock, if update the OS and bootloader maybe because will not recognize the OS and ROM even if it is all original, but i think it should...
I will tested and report... downgrade and re-lock the bootloader... But my bootloader is the same version it did not update because i use a ROM or a TWRP backup do upgrade to L.
I will update the ROM i using do a clean flash, before i will try the downgrade and re-lock process. :good:

yeah i'm talking bootloader I know you can go up or down between 4.4.4 roms and 5.0 roms , i've tried mfastboot, fastboot (different versions) as people say 'only this version works' and so far not found anything that works
Ever since I upgraded to 5.0 then downgraded 4.4.4 I can not lock the boot loader. I don't think anyone will be able to until there is 5.0 firmware

January ota had a serious bug, it caused bootloops on many devices with locked bootloader so they pulled it.
Just wait for february patch and my advice would be to unlock your bootloader now and keep always unlocked
Ok thanks for your advice..i just relock because that annoing message everytime i reboot phone..anywayto remove that warning with bootloader unlocked?
