Hello, I have a brazilian G5 Plus that originally didn't have the retail Nougat image Installed (bought form a carrier), but I was able to update to the leaked brazilian 8.1 update. The phone was never bootloader unlocked or rooted, however I'm willing to return to stock nougat in order to try Pie roms and not lose the fingerprint function. What I want to know is A) can i flash retail nougat images on my phone (as it wasnt retail at first)? and B) at what time should I make backups of EFS and Persist partitions?
Should I unlock bootloader while on oreo. install twrp, make backups of efs and persist and then flash stock nougat?
Or should I be able to downgrade to Nougat without any issues, and take backups of EFS and Persist before flashing Pie Roms?
Any clarification on the subject would be deeply appreciated.
Thanks in advance.

Don't try to downgrade your bootloader as it going to brick your device. If you want to make back up made the back up of Oreo(now in which your using) and nougat also, as we can't say where it goes wrong. And you can flash retail nougat image but don't flash gpt and bootloade so it don't brick your device.
Read this: https://forum.xda-developers.com/g5...o-twrp-flashable-stock-builds-coming-t3830482
If you want to try some custom rom and not lose fingerprint, all you have to do is run the persist fix, flash a 7.0 TWRP-flashable stock build and THEN flash your custom rom. No need to fastboot flash the stock image. Of course also backup your persist and EFS as soon as you first boot into TWRP.

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.
Hi there, I have the x1642 model on nougat with ElementalX and phh root. I wish to revert to total stock but cannot find a stock nougat firmware or how to flash one. Help is much appreciated, thanks.

For reverting back to Nougat, your best bet is to flash this stock ROM via fastboot. https://forum.xda-developers.com/moto-g4-plus/how-to/moto-g4-plus-xt1640-43-athene-npj25-93-t3549369 this is NPJ25.93-14, Dec 2016 security patch.
Instructions on how to flash are included, and if you​ don't wish to relock your bootloader, the OEM flash script will cover you. A few notes:
The extracted ROM takes over 2 GB of space, ensure you have that in the same place you install adb (or can set a path to your firmware location)
When flashing, you may see a security downgrade error when flashing gpt and bootloader partitions. That's normal, but if to want to ensure those partitions are not overwritten, edit your script to delete these lines:
Code:
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
Flashing this will remote TWRP, root and your data, so back up accordingly. You may wish to keep those backups off your device.
Updating to the latest OTA should be possible after flashing, however if you want to relock your device, best to lock it using this firmware before you install the OTA. If you've flashed or will flash the OTA (and your device will/is on NPJS25.93-14.4, March 2017 security patch), we currently are unable to relock devices (as the stock firmware we have access to isn't new enough!)
I've flashed this stock ROM onto my XT1642 (retgb) several times and have had no issues I can recall flashing or booting. Just ensure you read the instructions, backup if need be and good luck.
I have seen that there has been TWRP backups of the OTA that people can restore to get to the newest version of the Moto X pure software, I have also seen that there is a factory image that cam be flashed from fastboot. However I have not seen a version that I can flash from TWRP that will install the new 7.0 version. I am looking to install the new 7.0 moto x pure stock firmware without restoring someone's backup or doing a full fastboot restore (which will lock my bootloader). Am I just not searching correctly?
TL: DR
Correct me if I am wrong about the 2 current ways to upgrade XT1575 to 7.0.
1st way: Restore to complete stock (bootloader and everything)
2nd way: Restore someone's OTA backup from TWRP
3rd way: What I want: TWRP ROM that I can flash without flashing my entire phone to stock
Does the 3rd way exist?
4th option side load or recovery load OTA. https://forum.xda-developers.com/moto-x-style/general/guide-xt1575-update-to-nph25-200-22-t3680477 . You have to be fully stock. But if you want TWRP. I would fastboot flash Nougat. Cleaner install. IMO..I really don't have a clue why your 3rd option is even an option. But sorry your info is incorrect about locking bootloader after a flash. Skip the lock commands and you will be fine.

Twrp's backup hasn't all partitions, f.e. baseband stays at MM.

You can fastboot flash a full factory image without locking the Bootloader... That part is completely optional.

Thank you, I guess I was used to my samsung ODIN days where a factory image flashes everything back to stock. I appreciate the info, I will be upgrading this weekend then.
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.
Hello everyone, i installed the leaked soak test with the "apply update from SD card" on stock recovery after locking my bootloader.
One week later, i unlocked it again and flashed TWRP for rooting with magisk.
Even with root tweaks i still face problems with soak 8.1, due to the lack of custom kernels.
So i decided to flash Stock N (1st April) with the TWRP Flashable zip from @Jleeblanch , how i avoid IMEI loss doing that? If i backup Oreo's EFS with TWRP, it will be compatible if i try to restore it after flashing, or it's not even necessary?
The TWRP flashable zip files by @Jleeblanch does not have the commands "fastboot erase modemst1" and "fastboot erase modemst2" so your IMEI will be fine. However Stock Oreo does mess up with IMEI.
Flash TWRP flashable Stock Nougat by Jleeblanch. You will not lose IMEI, but there will still be a problem of persist (i.e you will lost IMEI if you flash Stock ROM via fastboot). So to fix persist, follow this thread: [Guide] [XT16XX] [Solve] Moto G4/Plus IMEI=0 issue
Losing IMEI is a persist related problem (Soak Test 8.1, and all 64bit Pie ROMs are causing this). So if you fix persist, then you will never lose IMEI.
I recommend you to take backup of EFS before this process (i.e while having a bad persist and working EFS) and also after fixing persist (i.e while having a good persist and working EFS).
EFS backup by Lyuu's TWRP takes a backup of EFS, fsg and persist.
Since you upgraded to Soak test from a locked bootloader, I strongly oppose moving back to Stock Nougat. Even if you go back to Nougat, MAKE SURE THAT YOU NEVER DO ANY OTA UPDATE. Whenever Official Oreo comes out, either flash it by fastboot or by TWRP flashable zip file (Jleeblanch said that he will make one for Official Oreo too once it's released)

Yes you can flash Custom ROMs from TWRP, however, I don't think you should right now.
I got my device hard bricked randomly from Custom ROM. idk what caused it, maybe some changes which I did or something else. If a similar thing were to happen with you, there's no guarantee whether the current blankflash would work or not.
