Hello,
Can I downgrade completly with the bootloader on Marshmallow and then upgrade to Nougat?
I want to lock my bootloader.
My G2 bricked after doing this. But I don't know if this would happen to my G4 Plus again

If you wish to simply re-lock your bootloader, the easiest thing is to flash this fastboot stock ROM (which is Nougat) and use the locking script as directed in the first post. https://forum.xda-developers.com/moto-g4-plus/how-to/moto-g4-plus-xt1640-43-athene-npj25-93-t3549369 Of course, this may wipe your data - so back up, and the relocking may or may not work, in which case you may have to wait for a more up to date fastboot stock ROM to become available.
If you were to downgrade to Marshmallow, you cannot downgrade your bootloader and GPT partitions, at best, your existing bootloader would try to prevent you from downgrading those partitions. At worst, you'll brick your device again if you were to flash those - though we've got possible ways of fixing that, it's not a route I'd want to go down. Flashing the rest of Marshmallow is no problem, however, ensure you have the correct MM firmware for your device and territory.
Will this version work for my country(Germany) without OTA trouble?

Should be okay to flash - the 93-14 build appears to be the global build that was deployed by Motorola, and should be eligible for the 93-14.4 (March 2017 security update) whenever that arrives in the EU/UK I've flashed the stock ROM onto my XT1642 several times without issue.

Hey guys
I have a question. I just recovered my phone from updating to Oreo, had bootloop all night and I painstakingly recovered to stock recovery and the earliest stock image possible, 4.5.3. My question is, do I have to go through all the updates one at a time ? For example from 4.5.3 to 4.5.4 and from 4.5.4 to 4.5.5 and so on ? Or can I update directly to 4.5.15 ? I'm definitely staying of Oreo. My phone is currently encrypted, not rooted, on stock recovery and the bootloader is unlocked. If I have to go through the updates one at a time, could you please provide a set of instructions to follow ? Like the steps necessary so I don't brick my phone again from the updating. Thanks !
You don't have to do all the update, a 1 time oreo full rom flash will be sufficient. Follow this instruction from HatRiGt and you're good to go

Hi everyone
I recently got a Verizon Pixel and i want to roll back to Android 8.1 Oreo, i am currently on Android P DP2 with a locked bootloader, i've enabled OEM Unlocking (done under Android P DP2) but didn't want to unlock the bootloader! how can i roll back safely! do i need to unlock the bootloader! if my bootloader is unlocked can i lock it back! what are the possible issues/benefits if a bootloader kept unlocked!
Thank you.
Just unenroll from android beta program by visiting android beta website and you will get an ota which will revert you back to android 8.1.0
I've heard that some people who did, got a softbrick after the OTA update! I want to roll back manually.

You have two options then first One sideload the latest ota file of 8.1.0 which is of june. And then wipe your internal storage . For doing this you won't have to unlock your bootloader . And the second One is unlock your bootloader and flash the latest factory image of android 8.1.0.. Backup your data because both will cause you to lose your data.

Thanks for the clarification, I have one more question, do you advise to let my bootloader unlocked or should I lock it back, knowing that I have a Verizon Pixel!

If u are into custom roms or rooting types things and customizing your phone then you should leave it unlocked .. as yours is verizon one you may not be able to unlock it in the future. Otherwise lock it .. ??

Pixel's are finicky as far as relocking the bootloader due to AVB and dm-verity. I highly recommend against relocking these phones unless they are COMPLETELY STOCK. Also if it is a Verizon device you will not be able to unlock it again without using an exploit which is a bit hard to find and a bit scammy
Can you please guide me how to manually update my AT&T v20 to be stock not rooted oreo, my h910 is stock never touched, not rooted of version h91010m which can't get updates as it is unlocked and am not in US.
All i want is just to update it manually to the stock oreo software.
Thanks a lot

Use this to root.
Instead of flashing the 10v att image like the last step suggests, use the 20g Oreo image instead
H910 Oreo 20g: https://androidfilehost.com/?fid=1322778262903991071
Thank @clsA for the Oreo link
Thank you
Thanks a lot for the clarification...
i have read more, i believe this rom will let me stock oreo so am worried i can't update the phone again in case of future updates.
is there a way to update in future? Also is there a way to change the software from h910 to h915 so that i can recieve ota updates normally in future?and is it safe as am afraid to loose signal or brick phone etc...
Thanks a lot in advance.

After you flashed the 20g Oreo image, it will be stock as if you took the ota update itself. You'll be able to accept ota updates after words. Follow the root thread, amd you'll be fine

The problem is i can't recieve ota updates even i am stock, it is AT&T restriction because my phone is unlocked am using other network (am not in us)
ota updates need to have a working AT&T SIM inserted in phone. It is very stupid policy for AT&T.
So my question now is, is there a way to convert h910 to h915 safely? Because Canadian operators allow ota to unlocked phones...
Or is there a way to manually upgrade in future after i upgrade to stock oreo?

why are you worried about updates when you can't take them now ?
Yes you can convert your phone to 915 it's the first step in the rooting process
if you want to stay 915 use the H915 Oreo KDZ > https://forum.xda-developers.com/v20/how-to/h915-oreo-kdz-link-t3826812
If you want a H910 on Oreo use my zip. If another update comes along their will always be another zip (provided we get root and TWRP for Oreo)
In case i will just flash the h915 oreo kdz, should i flash all partitions? Including modem, bootloader, etc...
Is it safe? Because in the guide it say i will loose the signal after flashing h915...
Also Should i still root first or can just flash directly?
Also is it safe to get future ota updates when software is for h915 and treat my phone as if it is h915 from the beginning?
Many thanks in advance.

You flash all partitions for non rooted stock which should work like normal with everything working.
My guide is for those trying to keep root intact so to preserve the dirtysanta eng aboot so there are problems with data at the moment.

I'm in the same situation as the creator of this thread, I can not update my phone from OTA
Assuming I do this to update. Would Android Oreo be rooted? Could I enter TWRP ?.
Since If I do this procedure and update my phone to Oreo and I don't have root or chance to get into TWRP . I would be stuck until there is some way to root the phone (if it comes into existence)
PS: I bought an AT&T sim card from eBay, but I couldn't activate it. Do you guys have any idea if the sim being activated I could update my phone despite not being in an AT&T network?

You will loose root and be back to stock bootloader so no twrp. It's stock oreo with no way of rooting it for now.

Just to clarify this statement a little. If you want to run Oreo now, you can't have root. However, you CAN downgrade back to Nougat and root when we finally have the Oreo + engineering bootloader issues worked out.
The US996 will be getting Oreo eventually, and that firmware is what is going to allow us to have rooted Oreo on models that use the engineering bootloader.
If the US996 wasn't getting Oreo, then I would waste the time trying to get things sorted out -- but that is just a waste of time.
We have waited for Oreo this long, waiting another couple of weeks isn't going to hurt.
As a final statement, I have had a chance to play with Oreo on my H910, and I am NOT impressed. What a ****poor, crap job that LG has done. It may get better with future updates, but I wouldn't bank on it.

I remember reading earlier this year about how LG was going to reform their mobile division, getting better at software updates and halting/slowing down the typical release schedule of phones.
Seems none of that has happened as far as I can tell, especially the software part. What a farce.
finally i updated my H910
i managed to updated my H910 by simply flashing the oreo H915 KDZ file with patched LGUP and it seems very good... signal is ok no errors so far except one after rebooting phone
ARB is still zero.
thanks a lot for all of you

Why do you think US996 getting Oreo helps? What if the eng aboot can't initialize the oreo modem properly (maybe intentional change)? I have a thought, maybe we can try if the stock nougat aboot, say H910, can boot the Oreo with data? We could flash everything Oreo stock and just leave the aboot nougat. Since signatures are still LG, it should boot up? And if it still can't have data, maybe eng aboot can never initialize properly, I don't know.
Questions about the H910 --> H915 Conversion
I have read several different postings on how to change the H910 to H915
I read the posting by runningnak3d and I am bit confused.
Sorry for the noob questions
1) If I flash H910 to the H915 v10e kdz, do I have to continue the steps to flash to oreo or can the phone be updated from OTA?
I really don't want the AT&T logos on my phone and I don't need my phone to be rooted or need dirtysanta.
2) Would flashing it with LG UP be enough to get Oreo?
3) I'm confused with the steps after downloading terminal emulator? - Do I need to do these steps if I want to keep the H915 Rom?
Sorry if my questions are dumb.
Thank you in advance.
Much appreciated

you can do as i did, just flash H915 KDZ Oreo file directly using patched LGUP and select to Partition DL all partitions.
you will have stock oreo H915 fully functional phone, there is only 1 error message that will appear every reboot of phone but will not make any harm.
there is no any issues or problems i have noticed so far, also the software seems more stock than AT&T version.

you can simply use lgup to backup your current setup (not userdata)
and use lgup to flash the 915 Oreo kdz
Note: someone said that converting to 915 caused google now to stop working but everything else was ok
if you want to return to 910 stock you'll have to do the root procedure and flash h910 10q or 20g back to stock rom from TWRP

1.Can we downgrade to 7.0 from 8.1? If yes,how?
2.Problems which may arise during downgrade?
3.If no why?
I'am fedup with the performance of 8.1,bootloops sometimes, network problems,and majorly battery backup and low volume issue.

Did you installed the twrp version of an Oreo rom or which rom do you have. Did you have an unlocked bootloader? How did you update to oreo?
Upgraded to 8.1 (stock)through adb,i have bootloader unlocked and also have twrp.(no custom rom installed)

You cannot downgrade the bootloader if you flash the stock nougat rom by fastboot, otherwise it's hard bricked.
But I don't know if stock nougat rom will work with stock oreo bootloader @echo92, you know it maybe?

If stock Oreo is downgraded to Nougat, the bootloader may work with either firmware, I don't know for certain. However, OTA updates must be avoided if there's been a downgrade to Nougat or earlier (unless you're using the Oreo OTA); attempts to use old OTA updates on downgraded firmware is a great way to hard brick (and currently without recourse - we do not currently have a working Oreo blankflash).
However, if you downgrade your firmware, I am concerned you may lose SIM access/IMEI, given your baseband is on .77R (Oreo), whereas downgrading to Nougat would result in a baseband of .62.02R due to changes between the 2 basebands. You may have to consult this thread if you do lose your SIM/IMEI https://forum.xda-developers.com/moto-g4-plus/how-to/guide-moto-g4-plus-imei0-issue-t3859068
@anhoxhrs Have you considered replacing your battery, or at least ruled out battery issues like a failing battery? I'm just wondering if the bootloops and poor battery life may be due to the battery. Also, when you updated to Oreo, did you clean flash or factory reset your device?
The SOT has reduced by 30%,and most of the battery is consumed by mobile standby(weird).Its a clean flash. being my primary phone, 8.1 is troublesome.Yeah the battery was pretty good before the update.Chargeing time also has increased.for eg- 95 to 100 about 1/2 hr to 45 mins.
