Hello,
after I've unlocked the bootloader can I still get OTA updates?
I'll just be on stock ROM with root. I also make a backup with nothing on except TWRP.
Lets hope so

have you tried it?
Yes you'll be able to get new updates with unlock bootloader.

Can you elaborate on this? The last I heard unlocking the bootloader (using the official procedure) stops OTA. Has this changed ?

I never said Official getting OTA's , but i believe this is going to change staring with the new Unlock Bootloader procedure.

OK, but AFAIK even with the unofficial unlock (with TWRP and root) the OTA will fail - unless you unroot and go back to locked stock bootloader. Correct me if I am wrong.

In my experience, what makes the difference - so far - is the recovery. Official ZTE updates and ROMS only flash through the stock recovery.
Unlocked bootloader has made no difference to me.

If you try to flash Official OTA yes will fail, cuz isn't modded to skip partitions check.

This is getting confusing. "Getting OTA updates" (as OP asks) usually means that the update installs "on its own" by tapping notification rather than flashing via recovery, which is a bit more complicated process.
So back to the OP question: With root and TWRP can one get over-the-air official updates from ZTE without going to the recovery manually? I believe the answer to that is NO.
That said, there is probably a work around in getting the update, probably by manually flashing partitions that have changed in the update.
Is this right?

Well OPs Question actually was if OTA Updates are possible with unlocked boot-loader...
Root and TWRP is a whole different scenario and won't work with OTA for sure as OTA needs stock recovery and will check for unmodified system (not rooted)...
But if you are on stock with unlocked bootloader you should get notified about OTAs (as until now it did not check for bootloader lock status, but that could change in future) although I don't know if it will install correctly

OP mentioned that he used TWRP to make a backup, I assumed he has replaced stock recovery with TWRP, but that may not necessarily be the case.
If your device has an bootloader that was unlocked "unofficially" (either via sideloading the official unlock method or DrakenFX & Unjustifieddev's method), but is still completely stock (stock System, stock Boot, stock Recovery, stock everything besides the unlocked bootloader), you can still receive and apply OTAs. However, if you changed any of the partitions, like boot.img (root), recovery.img (TWRP), system.img (changes to system), you will still receive the OTA, but you won't be able to apply it, the update will fail. If you went through the official bootloader unlocking process, which involved you submitting a form to ZTE with your device's IMEI, you would no longer be able to receive OTAs.
What I did was sideload the official B20_Boot on by B20 device, unlocked my bootloader, flashed TWRP, flashed the TWRP Stock B20 dumps that were posted here on XDA, and reflashed stock recovery. This made my device completely stock B20 besides the unlocked bootloader. I then applied the official B27 OTA update, and it installed fine. I then reflashed TWRP (since my bootloader was still unlocked) and re-rooted my device.
If a new update comes out, I can just reflash the stock B27 TWRP dump posted here on XDA, reflash stock recovery, (if needed, reflash stock fastboot), and apply OTA.

So, with this procedure, do you lose all the app installations/other customizations? I believe that all of the application data is on a non-system partition (/data?) but did you need to go through all of the setting up of the phone after you did the upgrade this way?

Yes. Unlocking the bootloader does a factory reset, and doing a TWRP restore of a stock image (which overwrites your current partitions) overwrites what you had before.
EDIT: Actually, I think Internal Storage gets erased as well, but your microSD card will be fine.

Hmm, had guessed as much. I knew the bootloader unlocking did a wipe, but was hoping that recovery-flashing would do a backup/restore, as if the update had been applied through the in-ROM update procedure. Unless the OTA process only gets deltas and flashes them, leaving fs intact.

Yeah, the OTA doesn't straight-up replace partitions, it checks and patches the existing partitions, so if a partition has been changed, the OTA install will fail.
I just want to know if it is possible to root and install twrp on htc 10 evo without unlocking the bootloader
Also I want to know if I was able to do this, will the phone be still receiving ota updates?

No need bootloader unlocked so can flash twrp it can get it's updates but have to do it a certain way and I'm don't remember how .I flashed twrp but having problems getting to it was problem on my phone good luck
Hey guys.
So I bought the mi a1 and was wondering if any of you could answer some questions that I have.
I was thinking of rooting my phone with magisk and TWRP as custom recovery. My questions are
1) If I relock my bootloader, will I lose root access and TWRP and will it also un-void my warranty ?
2) Will I still get official OTA updates after relocking it?
Thanks
1) With locked bootloader of course you'll lose all your root access and TWRP. It is stated that you MUST unlock bootloader to have root access and TWRP.
2) Lock or not doesn't affect the OTA. I unlocked the bootloader since the very first days and now I'm on the latest Oreo (and living with bugs).
So installing OTA with root won't cause any problems ?

After each update, if I get bootloop I'll just boot into TWRP&flash magisk, done.
But some people have problems, I don't know what they have done so I couldn't say for sure.

And also what about warranty issue. If I relock it, will it un-void my warranty ?

I'm not 100% sure as I don't work for the warranty center but I do think so.
When you mess around with bootloader or root or whatever which isn't official there are risks.
Hi everyone!
A have a few questions:
1. I unlocked the bootloader, rooted and installed Gcam. After that I noticed that bootloader was locked back again. Is that normal?
2. If I unlock bootloader again, it will wipe all my data or this happen only on the first time?
3. My phone is on May Security update(8.0). If I want to update later to 8.1, i'll have to do everything again?
4. Can I unroot my phone? If I flash my stock boot.img it will become unrooted?
Thank you!:good:

1. Yes,
2. If you are using may security patch or newest, you will need to hold volume down when unlocking and locking bootloader to prevent wiping data,
3. You can flash twrp fastboot flashable zip updates manually if you wan to stay rooted. If you do not like manual update flashing, than you need to back completely to stock,
4. It is alway recomended to fully flash your device to stock for the best performance.
Hope it helps.

I just rooted to test Gcam.
If I restore images on Magisk and update via OTA, the system will keep gcam?
Should I unlock my phone's bootloader before applying any latest updates or may it be possible that asus makes it impossible to unlock the bootloader in their future updates?
I'm suffering this dilemma for a while because if I unlock right now, my phone may not get any official updates.
But if I update to latest built, I may lock bootloader permanently.
Someone pls help

I Read somewhere in this forum that relocking bootloader is somewhat unsafe or not recommended.

Unlocking bootloader prevented OTA on all my ASUS devices.
Every time you go to check for updates, it will tell you there aren't any.
But you can download the software image from their site.
Then you can either flash it via recovery or copy the file to your phone's storage, it will detect it automatically and propose to install it.

I tried it on my phone but failed as my phone is on custom Twrp recovery.
