Downgrade LOS 19.1 to stock Android 9? - Motorola One Vision Questions & Answers

Hello, I would like to downgrade LineageOS 19.1 to stock Android 9. My software version, based on what imei check says, is "kane_reteu-user9PSA29.97-37c8dbrelease-keys". And my country is BG, if it matters.

Nevermind, I figured it out.

Hello! Got this phone since yesterday and been trying roms and co. I'd like to downgrade too or get back to stock. And i can't get a clue ab out those stock-firmware-filenames. Could anyone enlight me how to find the right one? Its a -3, EU device.
Nevermind, figured it out. Getvars ftw

I tried to flash back the original version https://www.getdroidtips.com/stock-rom-motorola-xt1970-3-firmware/ but the phone got hot and choppy when charging. After installing the Pixel Experience 12 Plus, the mobile works well. You need to find a stock version for your mobile on the net, there are several of them.

How to get from nougat/Emui 5 to Pi?

So my phone is downloading L09C34B171, I just got it 2nd hand and unlocked the bootloader.
I've seen some conflicting things on using emui 8 or 9, I want to install a rom like lineage or RRv7 with magisk but apparently i need to flash everything from emui 8, so will my phone be updated to this before going to the emui 9.1?
thanks for any advice, keen to get some sweet custom OS so emui can go away.
I believe you need to have a phone on PIE to use RRv7. I flashed RRv7 to my Xiaomi Mi 8 lite and it's so much better than what was on it before. I just flashed PIE on my mate 9 yesterday and it's great. Read the thread below and you'll see how me and another guy did it. My bootloader is still unlocked so I imagine I can just flash twrp for PIE and then flash RRv7 which I'm thinking about doing. Not sure that I see that much difference is 8.0 and 9.0 but it runs fine.

Oneplus 8T (Cyberpunk Edition)

I received a Oneplus 8t (Cyberpunk Edition). The phone was supposed to have HydrogenOS as it is a Chinese phone. However, the vendor installed Global OxygenOS (KB05AA). After OTA updates, the phone wouldn't reboot and would get stuck on the Cyberpunk boot animation.

OxygenOS
I tried updating/restoring OxygenOS using the the MSM download tools here:

forum.xda-developers.com
Pros: Google Apps and a Global ROM.
Cons: No OTA updates and no original Cyberpunk theme.
Best case scenario for OxygenOS users would be for Oneplus to fix the OTA updates for Cyberpunk phones. This would stop the bootloop problem people are having.

HydrogenOS
I have made a guide on how to restore HydrogenOS and add Google Apps:
Oneplus 8T (Cyberpunk Edition) - HydrogenOS (Google Apps, Theme, OTA Updates!)
Originality/HydrogenOS If you have a Chinese Cyberpunk Edition phone with OxygenOS, you'll notice that the Cyberpunk theme/assets are missing, and OTA updates lead to a boot loop. This guide will tell you how to restore the phone to its original...
forum.xda-developers.com
Pros: Working OTA updates, the original Cyberpunk theme, and Google Apps!
Cons: A little bit of time and maintenance.
________________________________________
Overall I would highly recommend trying the HydrogenOS solution I've linked above. It works excellent for me, so I won't be pursuing a solution for OxygenOS unless things change. The guide I wrote and linked above should get anyone with a Cyberpunk phone on to HydrogenOS (with OTA updates, original theme, and Google Apps).

Hi,
so even if we flash full OTA zip file of 11.0.5.6KB05AA version (or EU version) from the HydrogenOS, for future update we will not be able to use phone OTA?
Thanks,

Your results may vary, but OxygenOS' (KB05AA) OTA updates aren't currently meant for the Cyberpunk phone. Many people have gotten the bootloop issue on OTA updates.

Ok, so I have tried updating using EU version "Oxygen_15.E.21_OTA_0210" ==> resulted in bootloop. I wiped the phone and back to hydrogenOS.
Now I will see if I can flash the Global version and update this reply.
Edit:
flashing global full OTA "15.O.20_OTA_0200" also resulted in bootloop. I wiped and back to hydrogenOS.
only thing is confusing me is... how did the vendor install global oxygenOS and sell to people.
I've tried to contact their support team, so far 5 days no answer - I'm as confused as you @shadww... I'm currently just using it as a regular 8T, I've never had the phone in Hydrogen OS tho - build is Oxygen OS 11.KB05AA and update is to Oxygen OS 11.0.5.6.KB05AA...

Have you tried to do the OTA update?
I also have the 8T Cyberpunk edition running on 11.0.4.5.KB05AA right now, i have SOME Cyberpunk things (theme as well as always on display clock (no wallpapers) i have tried to install newest update with Full zip and gets me to bootloop, ill be in touch in case i am able to achieve anything.
I have already said they hacked the phones. I wouldn't be surprised if the Chinese sellers have a half decent working TWRP that they aren't sharing

Hacked, how so? It seems like all they did was obtain/install the KB05AA ahead of schedule. I guess it's all hearsay, either way.
I received my 8T Cyberpunk 3 days ago. I've requested the Seller to ship it off with HydrogenOS as stock so I can still have the original themes. They've also taken the liberty to install GApps on my HydrogenOS as well. So right now I can use Google Services and GPay. They have deleted all the Chinese Bloatware (But still kept Market, Wallet, Browser).
Running: Hydrogen OS 11.0.5.6.KB05
PRO:
GoogleApps (Playstore, Play Protect, Google Pay)
Original CyberPunk Theme with HydrogenOS
OTA HydrogenOS Update with no problems
CON:
AndroidAuto does not work.
Google BackUp does not work (Only Google Photo backup works)
Google Assistant can be dodgy.
Where did you buy please?

Yep - results in bootloop so I stopped trying and waiting for a solution or response from Oneplus. Currently using my phone as a regular 8T (with no cyberpunk theme)
Hmm I just ordered the Cyberpunk edition and now I'm worried we won't be able to update. Maybe the next update will resolve the issue?
Hi,
So I have some good news (I think).
I was trying to flash OxygenOS (Global and EU) on my HydrogenOS (11.0.4.5) Cyberpunk8T. It ended me bricking my device. (Yes, I was fooling around with fastbootd >_<)
I went to this thread: https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4180837/
and used the MSM tool @OniAraAra linked: https://androidfilehost.com/?w=files&flid=320230
I was able to get back to HOS (11.0.1.2). So this even downgraded my version, and I had all cyberpunk elements.
Then it hit me. I was trying to figure out how did the sellers flash the global OOS.... and most of xda members here state that their device came on "11.0.4.5.KB05AA ", and it had " SOME Cyberpunk things ".
So I went and did an MSM restore on my Cyberpunk8T HOS (11.0.1.2) to EU OOS 11.0.4.5 (from unbrick-tool thread above). Guess what it worked. I was able to boot to EU OOS 11.0.4.5.
Then right away, I did a local OTA upgrade using full package EU OOS 11.0.5.6 (https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4180837/).
I booted to EU OOS 11.0.5.6, have cyberpunk boot animation, wallpapers, theme, icon pack, and sounds (basically everything, let me know if I should check something specific).
ps: I also heard that local upgrade is not available on Global or India OOS, thats why I tried it on EU. Not sure if one does EU MSM, then flash Global Full OTA locally if that might work or not.

That is interesting. I wonder if there's just a problem with the international OTA file?

Not really sure. I did try previously local OTA to full EU OOS, but had the bootloop issue similar to international/global OTA.
There is also always the possibility that seller did not do proper global MSM revert? or that going to HOS and then again to OOS might do the trick? (not really sure here, I am just stating random possibilities)
Good thing is one can easily test using MSM tool to revert back.

That is pretty much what I am looking for! Cyberpunk theme with Oxygen OS and OTA updates. It seems from your method you can do the OTA updates. I assume this method will reset the whole phone correct?
Regarding version, does it matter If I use Global or EU? I am in US and everything has been working with phone service with the global OS, just no cyberpunk themes or OTA updates

1) So, it looks like fine to update through full OTA (EU) for me. I wonder if in the future I will have to wait for full OTA updates or can do incremental ones too (won't know until tested in the future).
2) Yes, this method will reset/wipe the phone. (see: https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4180837/ )
3) Regarding EU vs Global, I think there might be difference in some apps. However, I believe that bands information are stored seperate to the ROM, so EU or Global OOS should work fine from operation stand point. Also, I am not sure about 5G though, as I heard US has different standard or something. Not sure if that is also affected by OOS verison (I think it should be hardware thing though).

H840 Custom Rom

Is there any custom ROM for H840 version? I looked everywhere but nothing shows up. I just messed up my phone, wiped everything from TWRP and does not have OS now.

Did you ever find a solution, mate?
Only H850/H830/RS988 ever had LineageOS builds. Obviously you can install custom recovery (TWRP) on other versions of the LG G5, but that's as good as it gets since you cannot unlock the bootloader to boot into a custom ROM.
If you're stuck without an OS on other variants, you're better off doing a full restore using the LGUP software tool.
EDIT: It seems the SE H840 can also be bootloader unlocked officially by LG, although people have posted mixed experiences depending on what "region" it came from. From what i've seen through searches, people have been asking for custom ROMS for the H840 since 2017 but nothing has come up.
Bump... Just in case anyone has come across an alternative ROM.
I unlocked my UK H840 without issue .. just need a new ROM to replace the old stock..
Any news? Would like to install an application that isn't supported on stock Android 7.0.
This is not the right location for questions. H840 will never have custom ROM support in all likelyhood.

UK EE OnePlus 7 Pro 5g, Lineage OS - no sim found. Then global firmware also broke wifi.

Hello. I am fairly technical with web and computers but not so much when it comes to android or mobile hardware/sofware so bare with me.
I got my oneplus 7 pro 5g (UK EE network) back from repair yesterday and went to install lineage os on it following this tutorial https://wiki.lineageos.org/devices/guacamole/install with OpenGApps nano.
The install seemed to go fine and managed to boot into lineage, connected to wifi and then started installing my apps etc. Today I moved my sim over and could not get the phone to recognise the sim. Could not turn on mobile data, could not see a phone number in the about settings page etc.
I then started googling around and found this thread [OP7P] [Latest: 11.0.3.1] Android 11 Firmware collection | XDA Forums and in my limited wisdom decided to just start flashing the global firmware onto the device. After this lineage booted fine but now not only no sim/mobile network but also no wifi. I assume i have put the wrong firmware onto the device, maybe something to do with either my phone being a UK phone or the fact that it has a different modem for the 5g version of it.
I think it's time I asked some people who know what they are talking about rather than trusting my own poor judgement :/ Does anyone know how I can fix the wifi and sim on this device now? I dont mind if it is on lineage os or if it goes back to oxygen os.
Device OnePlus 7Pro 5g | Model: GM1917 | Build: lineage_guacamole-userdebug 11 RQ3A.210905.001 10035588
The OnePlus 7 Pro 5G doesn't have working modem on custom ROMs past Android 10, and me and others efforts to get it working have failed. This is due to different modem and partitions. You also cannot flash the international firmware on it. This will most likely break modem even more. The best you can do is flash the EU5G firmware going by GM27BA. (Found here https://forum.xda-developers.com/t/...rint-oneplus-7-pro-5g-to-european-fw.4042583/). Also Android 11 is not out and probably will never be out. The source for the 7 Pro 5G isn't even fully out so building custom ROMs won't work
Thanks for the info and the link. I really appreciate it.

So if I were to go back to stock oxygen os would that fix my modem alone or will I need to fix the firmware separately since I flashed the global firmware over the top?

Very strange boot animation in android 11 update

It seems they are sending android 11 to everyone but they changed the boot animation. Now when you boot you see a logo that says edge and then TIM italy. This did not happen in android 10. My moto g 5g is free retail with no brand on the box. I think there is a bug in this update. Is it possible to return to android 10? Also this update changed the intensity of the bars on the screen, now it is more generous but if you see the numeric values of Dbm or ASU these are much lower. I regretted updating so fast and I would like to go back to android 10 until 11 is fixed.
Lol, 11 will never be "fixed".
If the bootloader was updated you're boned.
Apparently on the OTA updates on at least some devices it's not being updated, you can rollback.
The 5th digit from the end of the boot loader version and the firmware are the significant digits. If the boot loader version is the same or less than the firmware, you can rollback. In this case it's a 2.

Check the software channel from Settings>Telephone information (or similar), which software channel do you have? If it is timit you are on the tim software channel (and the updates depends on the carrier, but actually seems in line with reteu, the european standar), if you are on reteu this is really strange. I don't know why they miss the boot animation but the firmware is right.
Yes the software channel is timit, but in android 10 it showed the boot animation for reteu channel. And i dont know why now it shows an edge logo animation that has nothing to do with this model. It looks like they put something from another model in the update. Look at the attached photo.
I'm using the euro android 11 XT2113-3_KIEV_RETEU_11_RZK31.Q3-25-15 on a XT2113-2 and everything seems happy as a clam, *except* it would not flash the radio.img. As far as being "boned" if you went to 11 but wished to downgrade.... Has anyone bothered to try a patched vbmeta? I could go up or down on my one action using this route. I think I may just try for the hell of it.
EDIT: downloading 10 now. If it works I'll post my patched vbmeta.
EDIT: Now keep in mind I am doing this from a flash of android 11 xt2113-3 on a xt2113-2 handset... The flash fails on the radio, then next the DSP. It does however downgrade the bootloader no problem. I went ahead and prepatched the boot.img prior to flashing, and it just finished sooooo survey says.......? It worked. Now back in Android 10 XT2113_KIEV_RETUS_10_QZKS30.Q4-40-95-2. Running through the setup now to make sure it dials out etc.
EDIT: Phone dials out, bluetooth and wireless works. Havent seen 5G yet but 4G/LTE is working for sure. So yes, you most assuredly downgrade from 11 if one so chooses. Attached is the vbmeta I used.

You can always just root phone and change the boot animation files. They're in system/media/bootanimation.zip
Just download android 10 firmware get this file from system.img and put it on your phone

Hello and sorry for asking a newbie question here but I don't want this to go sideways...
I have a new XT2113-2 (TM) that is yet to be boot loader unlocked/rooted/etc. I don't want to do that until I am sure. I got this variant of the phone so I could unlock the bootloader, root, TWRP, etc and was afraid the "global" variant -3 might not work with USA 5G. The phone came with Android 11 installed (and has since auto-installed at least one security update). It shows the build as RZKS31.Q3-45-16-3-11 and the baseband ends with Kiev_TMO_CUST. I am using it on ATT (via Red Pocket) since TM service just sucks where I live. And I do get the 5G icon on it now.
But ideally, I want to get this to the original TM Android 10, which I think is shown here as the file XT2113-2_KIEV_TMO_10_QZKS30.Q4-40-95-6_subsidy-TMO_SPR_RSU_QCOM_regulatory-DEFAULT_CFC.xml.zip as I hope it will undo some of the "security" crap Google has added to Android with each successive release.
So I need to be sure of the following:
1. Can I downgrade from 11 to 10?
2. Is there some reason to NOT use the firmware mentioned above? Should I use retail US (RETUS) instead? I am not sure the differences (it would be great if that would permit me to use this phone on Red Pocket Verizon but the IMEI now shows as incompatible on Verizon).
3. Must I unlock the boot loader to downgrade? I know I must to do other stuff and I have the unlock code on hand and ready to put it if needed. If I must unlock the boot loader to downgrade, will I have to re-unlock it afterwards? And, if so, will I have to go through the same process of getting a code or will the code I have now work?
4. How do I flash to do the downgrade? I have the Lenovo Rescue/Smart Assistant installed on my PC and was able to download the stock firmware (I assume it matches what is on there now) and stashed it aside. But is there some other tool needed?
5. Once I achieve downgrade, what is the best way to avoid having the thing auto-update to Android 11?
Thanks for your help with these questions.
