[ROM][8.1][STOCK][MONTANA] Android 8.1.0 Oreo - Stock Firmware (Fastboot & TWRP)

[_MsG_]

Where can I find RETEU version? CID 32.

Hello. I installed OREO 8.1 on MOTO 1799-22. The front camera and NSF do not work. No one will tell you the solution? Thank you friends.

Did you flashed complete rom with bootloader command? Its obvious because witout flashing bootloder you would not be in this situation. Actually I flashed wrong rom on my xt1799-2 and now screen dont turn on but detecting in Fastboot mode. Cannot flash original bootloder due to lower version. So can I flash that 8.1 rom as it has higjer version of bootloader. My only concern is that will my phone turn on after complete flashing of this rom??

Hi, unfortunately, I have removed my IMEI (I should read a guide before - I was thinking that everything is easy as it was with older phones). Additional issues are that I don't know why Baseband is unknown. I was coming back from Pixel to Stock 8.1, I tried to return to Pixel 9.0 but it didn't help. Currently, both IMEIs are equal to 0 and baseband in the unknown. Guys, any ideas on how and if I can fix this, or I will have a phone without phone functionality? fastboot getvar all returns correct IMEI. I have XT1794 from PLAYPL, I moved from Play rom to Pixel 9.0 official, and then wanted to do downgrade, then troubles started ... and of course - I don't have EFS partition backup.

Hi, I had this same issue. (on my case caused by flashing "fingerprint sensor fix" on TWRP). (I'm also on Pixel Experience after fixing it).

To fix try the following

1. Flash stock recovery via fastboot (NOT TWRP) , and then boot and update via OTA (wifi) until no more updates shows up. (You will LOSE ALL DATA, MAKE A BACKUP BEFORE).

This worked for my XT1791, good luck!

I am also having a hard time trying to go back to Stock after installing Pixel Experience ROM. The guides in this thread were not helpful to restore my Moto G5S XT1792 back to stock.
I need to say that I had no problems with my IMEIs because I used TWRP to make a full backup right after unlocking the bootloader, therefore when I "lost" my IMEIs I just flashed the correct module manually (do not remember the name of the module right now).

After failing to restore stock ROM as indicated in this thread, I found a Lenovo software that was able to flash the stock ROM again without using TWRP. It automatically downloaded the correct ROM and flashed it.
The software is LENOVO MOTO SMART ASSISTANT
https://support.lenovo.com/br/en/downloads/ds101291

After flashing stock ROM using Lenovo Smart Assistant I was back to the latest stock ROM 8.1.
The issues I have so far are:
- the message about phone being rooted still appears when turning the phone on.
- I cannot make any calls to emergency numbers. It dials the number (police, ambulance, etc) and it drops the call immediately

EDIT: obviously there is a thread about Lenovo Smart Assistant here in XDA:

Hey guys.

This is a guide on how to install official Android 8.1.0 "Oreo" on our beloved, forgotten, poor Moto G5s (montana). As you all may know, Lenovorola still hasn't released Oreo for everyone worldwide. Only a few Latin American countries are receiving the update, with Brazil due to receive it Soon™, since we've already received the August security patch (still Nougat though :/).
Update 2018.09.29: Brazil and India have also started receiving Oreo, but with a different build (OPP28.65-37-2).
However, this is Lenovorola we're dealing with, so I went ahead, captured the OTA and created a TWRP flashable zip, by patching the June firmware (NPPS26.102-49-11) with said OTA. And also, there's the standard .xml.zip to be used with fastboot, directly from Moto.
For those of you who want to keep everything stock, locked bootloader and all, I recommend going with the fastboot zip. For those who already have unlocked their phone's bootloaders and have TWRP installed, or are coming from a custom ROM but don't want to fiddle around with fastboot, you should use the TWRP flashable zip.

I can't stress this enough. ALWAYS BACK UP YOUR STUFF!!!! Do a TWRP backup (data, system, boot). I recommend backing up the contents of your internal storage as well. And for those willing to downgrade at some point, back up your persist and efs partitions, otherwise you'll lose IMEI!

Oh, and I assume you already have adb, fastboot and the Motorola USB drivers installed. In case you don't...
Motorola USB Drivers
Android SDK Platform Tools (includes adb & fastboot)
If you use Linux, you don't need to install any drivers, but you may have to configure udev to allow fastboot to detect your device. But that, along with telling how to configure adb and fastboot, is beyond the scope of this thread.
I don't know how things work in the Apple side, so kindly don't ask me how to do that on macOS.

This firmware should work on all Moto G5s models (XT1791/2/3/4/5/7). I can't tell if it works on model XT1799-2 (aka Green Pomelo / Qingyou).

A few warnings:
1. Forced encryption has not been disabled. So, if your phone is not encrypted, it will be encrypted again upon the very first boot. Don't interrupt the process, otherwise you'll lose ALL of your data! (You can flash @Zackptg5's dm-verity / forced encryption disabler if you want to)
2. Xposed doesn't work, whether it's installed to /system or via Magisk (systemless). I've already opened an issue on GitHub and am awaiting a reply.
3. (Fastboot only) Updating to this firmware will also update your bootloader and partition table. If you're unsure about that and/or afraid of a possible hard brick, skip the gpt and bootloader lines.
4. Please install the proper build for your software channel. For retbr and retin, use OPP28.65-37-2. For the other channels, go with OPP28.65-37.
5. If your phone's software channel is retbr or retin and you have already flashed the -37 build, you can simply dirty flash the -37-2 build over it. No need to factory reset / fastboot erase userdata.

With that out of the way, let's get to what matters most.

Thanks to:
@NZedPred for the excellent tutorial on how to build flashable zips based on stock firmware and/or OTAs
@Cesarcami53 for telling us that the update was out for retla

"4. Please install the proper build for your software channel. For retbr and retin, use OPP28.65-37-2. For the other channels, go with OPP28.65-37"

My phone used to be on channel reteu. What version am I supposed to use - because as "other channels" only retla is shown. Retla seems to stand for "Retail Latin America". So I can choose between Brazil/India or Latin America. Not close to EU... Will it update properly anyway? I want to be able to use the current LineageOS 17.1 rom so I need Oreo firmware.

Hi,
i flashed the needed parts from this with fastboot:
https://mirrors.lolinet.com/firmware/moto/montana/official/RETEU/
and LOS 17.1 works perfect (look in this thread, the very last post for the parts and in the thread for flashing stock roms)

Thanks for the link. I am not sure if I trust that source, though.

Except Motorola's own source, this is about the only good source you'll get

please guys can u help me_i have a moto g5s with lcd remplacement, dont work touchscreen with android 8, i downgrade to android 7.1.1 touch work well but not signal, imei and baseband ok, please need recover signal with android 7

 

[memetix]

Thanks for this - i came from LOS 14.1, TWRP flashed this using the latest TWRP v3.4.0-1 and everything seems to be working perfectly. I then tried to flash recovery but i keep getting:

d:\Android\mfastboot-v2>fastboot flash recovery twrp-montana-3.2.3-r1.img
(bootloader) slot-count: not found
(bootloader) slot-suffixes: not found
(bootloader) slot-suffixes: not found
(bootloader) has-slot:recovery: not found
target reported max download size of 536870912 bytes
sending 'recovery' (15914 KB)...
OKAY [ 0.531s]
writing 'recovery'...
(bootloader) Image not signed or corrupt
OKAY [ 0.170s]
finished. total time: 0.711s

I also tried the latest TWRP - v3.4.0-1 and get the same. I can fastboot boot both of these images but cant write them to the phone either via fastboot or from within the recovery. When I try to boot into recovery from the BL i get the sick android picture with "no command". I'm still on the old bootloader BC.06 maybe this is the reason? In the settings menu it says the bootloader is unlocked and also when I boot into the bootloader it says its unlocked so I dont think the BL has been relocked.
How can I get back a recovery and root? I want to get onto LOS 15, 16 or 17...Should I try the fastboot method to load this ROM and the new bootloader?
Thanks.

UPDATE: I fixed this by following this guide https://www.androidinfotech.com/root-moto-g5s-plus-oreo/. For some reason changing the file name of the recovery image to "recovery.img" seemed to work.
