Q about flashing new firmware updates for Zenfone 3(Ze520kl) with unlocked bootloader - Asus ZenFone 3 Questions & Answers

Hey Guys,
I've recently bought a Zenfone 3 ze520kl with the first ever released firmware version and I was also successful in rooting it with twrp installed. Since I used the official bootloader unlocker, I also couldn't receive ota updates. Now, is it possible to flash the newer firmware with a 3rd party app like flash fire and not lose root? i really want to update my phone for stability issues and i've also heard that nougat has just been released. Lastly, do i need to flash the firmware according to release date or is it fine to skip to the latest one?
Thanks for any help.

To do so you have to unroot your phone 1st, in Root guide for 520 in very last step there is a link to boot.img and recovery.img that you have to flash in fastboot, but 1st also in fastboot do erase system amd erase cache, which will wipe whole phone.

Should you need any help let me know.
Latest firmware doesn't mean most stable... Not for many at least. Im on version .79 which for me is flawless, .152 and few earlier builds it was a disaster.

Still waiting for OTA MM update

Hello,
I have an XT1562 single-SIM. I unlocked and rooted the device using TWRP 2.8.7-v2 and SuperSU 2.46.
Since I read rumours that this will prevent the OTA MM update I would like to update by flashing the new firmware.
This forum is a great source of information, but that information is scattered all over the place. I have read dozens of topics and hundreds of posts, and still have some questions . I hop this post will lead to the answers...
Do I need to upgrade TWRP to 3.0.0-r2 before upgrading the firmware?
Do I have to uninstall SuperSU first?
Can I skip the fastboot erase userdata step?
Will flashing bootloader and image re-lock the bootloader?
If I want to keep using TWRP, do I need to skip the fastboot flash recovery recovery.img step?
Thanks,
GeWe
Just wanted to get some extra information that may assist others in replying to this thread my good friend.
What version of software are you running? (Brazil Retail, Europe retail, Asia retail, Canada retail, USA or a Carrier branded version)
I will attempt to answer your questions as best I can.
1. I don't believe you need to upgrade to TWRP 3 to receive a MM version. I am running 2.8.7.0 IIRC and am running MM just fine.
2. You need to be completely stock to receive an OTA update. ie, no custom recovery and completely stock firmware. In Fastboot it should say "Stock" next to "Software Status" instead of "Modified"
3. You can when flashing original stock firmware, I don't recommend it though as I have had bootloops in the past. Best to backup and completely start fresh.
4. You don't need to relock the bootloader. I did this on a Moto G and then had to get the unlock code again to go back to custom. It doesn't completely relock anyway, it still says Status 3 I believe and shows the bootloader unlocked warning.
5. Again, best to flash completely stock then flash TWRP recovery.
All that being said, your best bet is to use the Stock backups in TWRP and restore from them. I used the Canadian one and am running TWRP with Canada firmware and haven't looked back. I will get you the link shortly.
Edit: this is the link. I used the Canada firmware in this thread and restored on my phone. Works great.

Sorry, I forgot to mention the software version. Apart from the recovery it is running the stock ROM, Android 5.1.1, European retail verion. (Baseband version is M8936_2020613.22.03.21.33R LUX_EMEA_CUST.)
After some more searching I found another thread that contained a link to the reteu OTA file. I followed the instructions there and now I have 6.0 running.

You mean a method like this? https://forum.xda-developers.com/moto-g4-plus/how-to/xt1644-stock-marshmallow-to-nougat-t3540022
If you download the 93-14 Nougat firmware, that's the latest version. Nougat OTAs currently only exist for the 93-11 firmware.

Yes, your bootloader status won't matter - as long as that's all you've done. As I understand it, the update via stock recovery only cares if the rest of your phone has been modified - if you've still got a stock bootloader, stock recovery and stock kernel (from MM, provided it's up to date), it should work and you should be eligible for future OTAs.
The only hurdle I could see happening is that the build of Marshmallow expected by the OTA and your phone's current OS build do not match, in which case it won't install. Thus, you may have to consult one of the fastboot Nougat 93-11 or 93-14 threads to install, which you'll have to do if your system is modified past the bootloader.
Here are a couple for your perusal:

Thanks for the brief info, it means i have to flash it via fastboot and if that works fine then I'll be able to get OTA, but for your info, I've unlocked bootloader and installed Official TWRP but if i flash any of the firmware (given above) will i face bootloop kinda stuffs? I am scared if something goes wrong then i will even not able to restore nandroid backup. Hope you gotta help me.
Thanks.

I see you've received a response in the other thread regarding if XT1644 will accept the update; given you've flashed TWRP, if you wish to be very safe, I would suggest re-installing your Marshmallow ROM so you have a stock install before proceeding to Nougat. There's nothing stopping you from directly flashing Nougat, and the fastboot method for either Nougat build may correctly overwrite the relevant files, the only way is to try the procedure. Don't use the TWRP backup images of Nougat - they don't contain updates to your baseband modem and other core parts of your device - they are only meant to be used once your entire phone is updated to Nougat.
If you wish to restore back to stock MM before flashing Nougat, here's links to stock firmware for XT1644: https://forum.xda-developers.com/moto-g4-plus/how-to/xt1644-firmware-t3454980
But either way, read all the instructions first, ensure you've got all the firmware and tools you need installed/downloaded, your phone has at least 50 % battery and plenty of time, and you should be okay.

Not receiving system updates

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.

Custom ROMs and future updates. What do I have to bear in mind?

So, we all know Motorola will eventually (aka never) release Oreo for the G5 Plus.
I am way too anxious so I am going to flash a Custom ROM until they deliver it. However I am quite afraid about something.
I plan to use Lineage 15.1 until Oreo comes out for the G5 Plus. However, I am kind of afraid that I may screw things up when the OTA comes out.
I have recently hard bricked my Moto G 2014 because of OTAs and Bootloader.
So, Oreo releases...
Will it be fine to install the OTA (through normal System Update check) having the latest Stock ROM Firmware for my region installed? (I would erase Lineage 15 and use fastboot to flash Stock again)
Or will I instead need to wait for someone to post the system images and flash it through fastboot instead? (I assume I would need to install the OTA through normal methods because of bootloader changes but still...)
I just don't want this: https://forum.xda-developers.com/g5-plus/help/moto-g5-plus-hard-bricked-t3694119
To happen.
You won't get system updates when you are on a custom ROM like Lineage OS or any other custom ROM. The only system updates you might get are ROM updates if the ROM maintainer has that feature built in.
If official Oreo comes out and you are on the correct stock firmware for your model and region, everything should work fine.
Before flashing custom roms you should backup your efs partition using twrp else you could lose your imei(recoverable) / volte(not recoverable till now) when flashing fastboot firmwire.
You need to flash fastboot firmwire to receive oreo ota.
If you want to avoid hard bricking, then you must flash the same stock ROM or newer onto your device when you revert back to stock firmware.
I imagine your Moto G 2014 got bricked when you took an OTA update? That could have occurred if firmware older than what was present on your device was flashed (bootloaders cannot be downgraded), and like in that thread you linked, attempting to use OTA updates would corrupt your newer bootloader with the older OTA patches, leading to a hard brick.
As mentioned above, if you revert to the correct build for your region and matching your current build at least, you should be okay to receive OTA updates (should also include up to Oreo). Alternatively, you could wait for the Oreo fastboot ROM to be safe, or the Oreo TWRP flashable for a near stock ROM experience (since TWRP flashables shouldn't care about your bootloader or GPT partitions, do it'd be difficult to brick your device. However, TWRP flashable stock ROMs aren't OTA compatible).
Before you unlock your bootloader and flash TWRP/custom ROMs, make a note of your current build version and see if you can find a stock ROM leaked of that build, so you can be sure that you're reverting to the right build for your device.
Just do not flash older stock Motorola firmware to your device or if you do, do not use OTA updates.
Yeah, I did some research and now I understand what happened. Thanks for the comments.

Help :(

I'm stuck on opj28.108 and I do not have the bootloader unlocked
We don't have the OPJ28.108 to OPJ28.111-12 OTA available as it was not captured. That's one of the unfortunate risks of using a soak test.
Your options to get unstuck would be:
1) wait for the Oreo fastboot stock ROM to be released. No idea when that will be but that should let you formally update to the stable Oreo build, and hopefully save your data.
2) unlock your bootloader, erasing your data. Then you could either flash Nougat again (risky) and then take the OTA update to the stable builds. Or flash TWRP and use the TWRP flashable.
