I unlocked my bootloader but am otherwise stock - did not install TWRP or any ROM. I see the Nougat OTA, and would like to test it out before probably moving on to CM14.1, but I am trying to be cautious.
For anyone who knows well enough or has tried it in my situation:
Does it seem likely that if I apply the stock Nougat OTA I will (a) break something since my BL is unlocked, or, if I succeed (b) have difficulties moving to CM14.1 later?
A little concerned about (a) but think I was told it shouldn't affect OTAs. And for (b), I read in the CM 14.1 thread various concerns about modifying boot partitions when moving to Nougat on CM, so I'm not sure if there's trouble going between CM and stock,
I haven't gotten the ota yet but I've heard that as far as it is about the unlocked bootloader you should be fine.

Since you are unlocked you can go ahead and flash ota if you want, it won't break anything.
i have my A7 with the BL unlocked and could install the OTA without issues.
I unlocked my bootloader (not rooted/no TWRP) and updated successfully last night.
My Phone Info:
Single sim 2gb ram + 16gb rom

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.

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!
I have got two G4, one with Marshmallow and one with Nougat.
The one on N (offical N, updated by OTA and did a full wipe) has lots of problems with BT, and I want to downgrade it to MM.
I have read lots of posts, here and everywhere else, and saw some vids about the procedure. But I still have some doubts about the proccess:
* Most of the procedures I have read relate to downgrade from N leak to MM in order to upgrade to official N. I have seen someone ask if the same procedure could be used to downgrade from offical N, but no answer. Can I use the same procedure to downgrade from official N?
* Some say you have to unlock the bootloader, others make no mention of it. Some say you should not write gpt.bin and bootloader from the MM ROM as N udated them and it is not possible to downgrade them. Do I have to unlock the bootloader before using fastboot to write the MM ROM? Should I avoid writing gpt.bin and bootloader?
I don't mind voiding the phone warranty, and I don't mind not being able to OTA update future versions.
Thank you very much.
Regards.
If you have bootloader locked, you can't overwritte nothing including system, boot, bootloader and gpt. I tried with my Moto G4 and i can't go back from official N to official MM through fastboot
Thank you.
So I understand I have to unlock the bootloader.
Now I just need to make sure if I should overwrite gpt and bootloader with MM versions (coming from stock N) or not.
Regards.

A couple of weeks ago, I read something about it. I think you should not overwrite the bootloader and recovery but I do not remember very well.
But if you have your bootloader unlocked just flash (or boot into) a custom recovery and make a backup of everything and after play along a while

Thank you.
Based on the overwhelming popularity of this thread (thanks lerg96!) I have decided to come back and tell how it went.
I had a Moto G4 with official Nougat. I wanted to downgrade it to MM.
The first problem is that I didn't find the .63 ROM (last MM one) for my device (XT1622). I found the 23.5 version (previous one), and the .63 version for the XT1624. Since 22 and 24 differ on LTE bands and so, I decided to use the older but right ROM.
First attempt: downgrade without unlocking bootloader... NO WAY.
Second attempt: unlock bootloader + downgrade without overwriting bootloader and gpt.bin. :good::good:
I got the boot warning message, but everything went ok and my BT problems are gone. I got the .63 OTA notification, but didn't installed it as I read scary histories about doing it.
Regards!
now that your bootloader is unlocked, install TWRP and make a backup of your system. I used TWRP to restore my OS. I went from Nougat back to MM, I am sure you can go the other way around too.
also, the fastboot method for reload the os seems to work well on phones with unlocked bootloaders.
Hello all.
Im a little bit confused about the bootloaders and their marriage with their standard ROMS.
I am in MM B13 in a 2017 unlocked using bkores toolkit and would like to check Nougat ROMS.
What happens if, from this MM unlocked state I flash an official Nougat for 2017? Is safe? Could I eventually flash a TWR to return to my "original and safe" state? Could I flash back an "official" MM B13 for example?
I am guessing that maintaining the phone in the unclocked area is safer than recover the lock. Is this true?
There is a "Universal bootloader" for Nougat ROMS. How "Universal" is this bootloader? Does this bootloader runs in MM?.
If I apply a SD "complete" update (being MM B13 or Nougat), do I relock the phone's bootloader?
If I upgrade fro MM to N, do I lost the possibility of flashing a custom recovery? (TWRP). This is a non go for me, as you cannot go back...
Hope you can answer these questions

Forget about the bootloader thing for now - it should be universal for MM and N. Not gonna relock itself.
-If you want to go back from a custom ROM (you'd have the A2017X_Universal_Bootloader, the ROM and the modem that goes with your device, plus a version of TWRP installed) what you would do, at least in A2017Gs and Us, is to flash a stock recovery zip to get the stock recovery. After that you reboot to the recovery, and you'll get to MiFavor's recovery. from there you would flash an official zip and every partition would be overwritten with what's on the zip. I suspect that ZTE packs every update with everything in it so that you can roll back, say, from Nougat to Marshmallow officialy, without messing everything up.
OR you can use MiFlash to reflash everything with a computer. Just download the full EDL file from 4PDA and flash, you'll get full stock (but still unlocked BL anyways)
So yeah, you CAN get back to full stock anytime.
-Don't just try to relock the bootloader. AFAIK if you relock it and you have root or TWRP or somesuch you can brick your device. I'd advise against trying to do that, but if you must, look at a guide or two at least.
-Yeah, pretty universal. I wonder why you'd want a custom MM ROM though. if you want to go back to stock MM it will get replaced by another one anyways.
-Already addressed, no
-I don't know the exact case with A2017 phones, but you said you cannot go back? You can. If you're on official N and want to roll back all you have to do is put an official MM zip on your SD or internal storage and go to Updates.
That being said, you still can use axon7tool on Nougat if it supports A2017 phones, which it should. You use EDL mode to flash the recovery. it is what I always do on my A2017G.

So...
i) Bootloader unlocked is safer than locked and problems can arise if i try to relock.
ii) I can flash from SD every official thing published by ZTE if I flash previously ZTE recovery. (bootloader still unlocked). From that startpoint, I could reflash TWRP using fastboot or EDL. Once in TWRP, every ROM is flashable if partition compatible...
iii) I can stay with my unlocked bootloader with every MM or N. Important things are the modem and other stuff. N is not much different from MM and I like Xposed....
Big, big THANK YOU!!!!

INTENTIONALLY DOES --NOT-- LOCK BOOTLOADER!!!
Get factory images here:
https://forum.xda-developers.com/mo...ock-images-t3736767/post75236696#post75236696
THIS GUIDE IS FOR FACTORY/STOCK ROMs - NOT YOUR AVERAGE CUSTOM ROM which may not have bootloaders!!! (thanks!!!!! @echo92 )
FIX:
IF YOU ARE ABLE TO GET TO FASTBOOT THIS SHOULD WORK.
IF YOU HAVE 8.x bootloaders AND ARE DOWNGRADING TO 7, use "Alternative to RSDlite" below.
1 boot to win - 7 or 10 works fine.
2 boot phone to fastboot, and connect phone to computer.
3 start RSDlite
pick a ROM. I believe I used a 7.1.1 rom
3Nov9-ADDISON_NPNS26.118-22-2-8_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip
RSDlite installed it and fixed the problem.
- -
I was then able to use RSDlite to install @rafikowy 's signed 8.0 . - going up from 7 to 8.
- -
- -
If you are on 8.x bootloaders and want to go to 7.x bootloaders, use this (RSDlite throws an error and stops):
ALTERNATIVE TO RSDlite:
1 I used 7zip to extract that 7.1.1 zip (or any ROM zip) into a folder x,
2 add all the adb and fastboot junk to folder x,
3 add the attached file (rename it to flash.bat) to folder x.
4 boot phone to fastboot and connect to computer.
5 click on flash.bat - it throws a lot of "slot" errors but works just fine.
6 reboot your phone if it hasn't already and go through the 7.x install stuffs.
7 you will not show an IMEI if you are coming from an 8.x bootloader. However, it IS there.
NOTE: you may need to add a line to the flash.bat if there are more/less sparsechunk's in your FACTORY/STOCK ROM...
THIS IS NOT FOR CUSTOM ROMs!!!!!!!
EDIT: 3-8-19: I just did this myself to go back very briefly to 7.1 - be sure you don't flash TWRP to it if your going to take OTAs - it will brick it. boot to TWRP if you need TWRP briefly: fastboot boot twrpimg.img
----------
If you can boot to fastboot screen, you can do anything.
Never OTA a ROM if you have modified recovery (TWRP, etc) or if magisk is present.
https://forum.xda-developers.com/mo...p-flashing-t3813498/post77011495#post77011495
I changed the attached file to add pause and reboot and exit to make it slightly more automated.
I have successfully used this many times going back and forth. If you can boot to fastboot screen, you can save your phone and flash anything you want.
You may wish to advise users that if they downgrade to Nougat not to use Nougat OTA updates. The reason being that a downgraded stock Oreo device may still have the Oreo bootloader on it. Thus, attempting to use Nougat OTA updates may hard brick their device (as the bootloader is likely corrupted, meaning no fastboot).
Users could either use the Feb 2018 NPN26.118-22-2-17 firmware from your link https://mirrors.lolinet.com/firmware/moto/addison/official/RETAIL/ as that was the last Nougat firmware (and thus no Nougat OTA updates) or avoid using OTA updates whilst downgraded.

Interesting. I used the above GUIDE to go up and down a number of times on my phone (about 20 total) , installing and running on both 7 and 8, and then went down to a Nov 7.1.1 and let it ota all the way up to 8.0 and that is what I am using now. I found that when i used a factory zip, and the above procedure, it corrected the bootloaders to the appropriate version that i was flashing - either RSDlite or the more manual path which ignores the errors worked for me.
Using the above procedure , you get the correct bootloaders, which are in the zip.
Please correct me if i am wrong!

That's intriguing - we saw previously on Z Play that users downgrading their stock firmware (e.g. https://forum.xda-developers.com/moto-z-play/help/hard-brick-moto-z-play-patch-abril-t3782927 )and then using OTA updates hard bricked their device (hence the number of users asking for a blankflash, as fastboot no longer works). I don't know if these users hard bricked by downgrading their firmware too far and then flashed an OTA radically different to their previous firmware, or whether it's a risk that's taken by any downgrading of firmware.
When you used fastboot, did you see any 'security downgrade errors' when you flashed the bootloader, and is your bootloader version now C180, as you've flashed the Oreo OTA?

YES - that's why I wrote these 3 guides - before, it was quite possible to wind up with a bootloader mix - esp depending on the zip you use! - factory/stock only!!!
I added a line to the guide saying that it is only intended to be used for the factory/stock zips as these have (I believe) the bootloaders appropriate to the ROM.
Many thanks for pursuing this! - I wonder if we'll have to exclude certain ROMs that are in the factory lists?????

If you have TWRP (or I assume any custom recovery) present when you try to ota, it can download just fine and then reboot to the update. I had TWRP and wound up in a situation where my phone would only boot to twrp no matter what I flashed or restored. I booted phone to fastboot, RSDlite'ed that 11-09-17 factory zip and all was well. In that particular case I did not fully install 7.x but immediately RSDlite'ed rafikowy's 8.0 signed stock and went on with my testing. Since then I always boot to TWRP rather than intalling it and do my thing. (thanks @jceballos )

1) If you have TWRP, then using an OTA will fail - as you've not got stock recovery (and likely other modifications, including possibly a system partition set to read-write status). As you noted, having TWRP seems to cause a bootloop when rebooting - I'm not sure if the OTA sets a boot flag to stay in recovery until the update is completed. For the G4/Plus, there's a possible solution by wiping the misc partition but I don't know if there's a similar partition for Z Play devices: https://forum.xda-developers.com/moto-g4/help/troubleshooting-twrp-boot-loop-ota-t3714325
The only other solution I've seen is a clean flash of the stock ROM to get your device booting properly.
Booting to TWRP rather than flashing would mean your stock recovery is still present on your device. The only downside is if you need to make modifications, you'd need your computer to boot to TWRP.
2)BL C1.82 seems to be the bootloader provided by the Oreo April 2018 security patch update, so your device looks to be on the right bootloader. It's still curious that the Nov 2017 firmware worked whereas countless other 'factory' stock ROMs caused hard bricks when downgraded to and then OTA updates were installed.
As you mentioned, custom ROMs don't have bootloaders and thus don't care about your bootloader version usually (though I've seen some ROMs require a certain bootloader). However, stock ROMs and stock OTA updates do have bootloaders, which is why downgrading can be risky.

Downgrading is a piece of cake if you don't use RSDlite - it throws an error and stops. Using the bat file it can happily throw all the errors it wants and all I care is at the end I have what I want.
It does indeed change the entire environment when you bat file the zip contents. You can bat file to get from 8 to 7 and then use RSDlite to flash a different 7 OR 8 zip file. There is no resulting difference in whether you RSDlite it or bat file it - the bat file simply comes from the .xml file that is within the zip. There is very little or no difference between that among addison factory/stock zips. Other zips are different (custom ROMs.)
Grab any factory/stock zip for addison and expand it and you will see modems, bootloaders, indeed absolutely everything you would find on that phone if you went to a store and bought it. SupahCookie simply added a couple lock command lines because it was intended for folks who somehow thought that if phone was locked they could take it back to the store and get their money back. Or some such. I found that ATT folk didn't care if you were on CM or whatever if you just needed to swap SIMs or whatever.
I DON'T want to lock the phone as it prevents me from modifying forever. Oh yeah that reminds me I was going to post the obligatory guide (again) about how to flash a white boot logo so you don't get that message - it's still there LOL but since the font is in white, you can't see it.
I have a Moto Z2 Play and used this to get out of a rather sticky situation.. My IEMI shows 0 now and I'm curious if there's a way to fix this? Also, You say you've done OTA updates? My phone is telling my I have some, is it safe to try?

Thanks for feedback and great on success.
IMEI will show zero if using oreo, It will show again if using N. Remember that if you go from O to N you need to use the "Alternative to RSD" as RSD will simply throw an error and stop.
If you have TWRP and/or Magisk you must get rid of them before ota - if twrp present you will soft brick and have to do alternative again - flash a stock recovery. Simply uninstalling/flash magisk will probably not be enough - it will likely d/l but error part way through update. If you are sitting on rafikowy's stock oreo, and haven't modified it, you should be fine. I know Apr and June are out there. I flashed his stock 8.0 and took June fine. Z2 should be no different though of course I can't guarantee it
If you have success, let us know what you have done so others looking in will know. Thanks!

I actually flashed to this: ALBUS_C_7.1.1_NPS26.118-24_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip Which is a 7.1.1 variant and it is showing 0 when I check settings and when I dial *#06#. However upon connecting to the computer and running mfastboot getvar imei it returned a value. I only did the steps above which would mean I don't have TWRP or Magisk (when I fastboot and click recovery I get "no command")
****** Additional information *********
XT1710-01 Duel Sim Variant
I started your steps, only being able to access fastboot. The device would throw an error (I don't recall exactly but it ended up showing me them in the bootloader logs) whenever I tried to start it, or go to recovery. #DefinitelyThoughtItWasDead

What rom was on phone when you got it and what have you done to it? Has it ever run 8.x?
original country of phone?
The bat file will always throw a lot of slot errors.

might have some stock ROMs of interest...

It had 7.1.1 stock. I rooted it, and then flashed Resurrection Remix (which was yes 8.1 I believe) and the upgraded bootloader. I then found out my service wouldn't work with that.. so I attempted to flash back to stock which gave me a flurry of issues.. eventually getting to nothing but fastboot working. Flashed back to working with your guide to 7.1.1
If it helps in in fastboot it tells me BL: C0.CD

Custom ROMs won't usually update the bootloader (even if they are newer) as stock ROMs typically only have the bootloader firmware.
You could look into flashing the stock Oreo albus 8.0 ROM https://forum.xda-developers.com/z2-play/how-to/fastboot-rom-oreo-retail-via-fastboot-t3786153 or the 8.0 June 2018 firmware https://forum.xda-developers.com/z2-play/how-to/fastboot-rom-albusretail8-0-0opss27-76-t3822195 but please check that firmware has been released for your device variant.
I don't know if updating your baseband to stock Oreo formally may fix your IMEI issue.

"BL: C0.CD" even right after flashing that albus 7.1.1 using "alternative" above?
What happens if you flash one of the oreo roms from the links I gave you above?
Yeah, RR wouldn't change bootloaders... so you upgraded bootloaders independendently?- that could easily lead to a soft brick... -
I read RR on Z2 and it says nothing about bootloaders even though it says 8.1 based, so i wonder if it needs 7.x bootloaders? I did not read entire thread...
In a reverse, I would wonder if you put an 8 on there if you wouldn't see your IMEI. (On the Z if you flash 8 You won't see the IMEI until you return to 7.)(wondering if z2 is reversed)

Yes, right after flashing that is the BL that fastboot is showing me. I don't recall updating the bootloader so to speak, however RR did require an updated variant of twrp which I flashed 3.2.2 I believe to get (unsure if that would have changed the bootloader or not). I also tried flashing a stock Oreo (which you've stated stock Roms usually only have the bootloaders so maybe somewhere during this process I updated it?). I wish I had all the notes for what I did to give more precise information, but I'm in a position where I really need my phone so I kinda just panicked and started flashing things when my service wouldn't work.
I'm highly considering trying to run an OTA (though very afraid of bricking). - On a side note though, it wouldn't even tell me I had OTA's until I did the steps in the original post here (doing the different 7.1.1. and 8.0 flashes, it wouldn't ever tell me I had updates, and now it does).
*** Edit ***
Looks like I'm able to enter stock recovery, which makes me believe everything is stock at the moment.

If you flashed a stock O that would have changed bl to O, but doing the above with the stock 7.1.1 would have changed them back to N. No matter (other than academic) that you don't remember the path - flashing a stock anything reverts it to that point in time. However, IMEI may have been moved - don't know. It will likely show on EITHER 7.x or 8.x stock - just don't know which.
If you flash a stock 8.x from those links I gave you above, it should offer you ota, ASSUMING there are any at this point in time(Z has 2). Adding Magisk at any point seems to hose you for receiving any more ota's - don't understand why, even with magisk uninstall, so that would mean going back to the latest stock and losing what you have (which is why I try to take a TBPro and copy that backup to PC (because re-flashing 8.x stock will likely reset internal storage.).
yes, if you enter stock recovery, you are likely at stock, though you could reflash the latest 7 or 8 stock to be sure, depending on which you want to use as base. Since 8 is having security fixes released, I choose 8 and will likely have no more interest (no time!) in 7.
So, ran the OTA and it was fine running the update and staying on N. I also downloaded the OTA for Oreo, when trying to update the recovery error'd out. It looked like the error said "Error in modem unexpected results" or something similar.

did it offer to let you d/l it again? you could try that.
However, there exist O stock zips in those links I gave you so you could just flash the latest...
