Stuck on EMUI 9.1 after downgrade - Huawei Mate 20 Questions & Answers

I downgraded from EMUI 10 a few weeks ago to see if I could fix an issue that came up when I upgraded (mic no longer working on calls). It didn't fix the issue so I want to go back up, but am constantly told that the phone is up to date, whether that's through HiSuite, the update app, or anything else. I've tried a factory reset etc. Does anybody have a suggestion of how to do this manually, or am I now stuck on 9.1?

[Q] Android 4.4.2 Issues

Issue resolved.
MiasmicTaco said:
This morning my Razr M received the latest OTA update. I was previously rooted with a locked bootloader (I know, bad choice).
I proceeded with the update but my phone massively screwed up: lost wireless, contacts malfunctioned, several apps failed.
I went through all the steps to clear cache, soft reset, hard reset, etc. Ever sense my phone has been stuck on the setup wizard screen stating "Please wait, this may take a few minutes". I left this morning at noon returned home at 7 and it is still on that screen.

Try using RSD to restore to the same version (4.4.2). I've gotten that wireless issue before, and I just had to format userdata and reinstall the update to get it working.
just roll back to orginal firmware by using RDS and after that,use OTA update

AT&T LG G4 Won't Update! Help!

I'm currently running Android 5.1 Build H81010e.
Since last week, my phone has alerted me that a software update is available. I start installation, the phone resets, and the notification comes right back after 2-3 minutes. It's been in an endless loop for at least the last week. Now my phone resets every 3-5 hours attempting to force the update, but it doesn't seem to ever install.
Anyone else having this problem on AT&T? Is my build the most recent? Any ideas on how to fix it?
If you want root, don't take the update.http://forum.xda-developers.com/g4/help/how-to-prevent-updates-g4-t3148650
If you don't care about root, go to Settings > Smart Cleaning and use the cleaner. It may remove the update file and let you download it again.
Since AT&T blocked recovery mode, there's no easy way for us to clear the cache, so you may need to factory reset to get the update to download again.
Apologies for resurrecting an old post however this is the closest forum topic I can find. I have a G4 and I have the same issue as above. I keep getting a notification of a software update and when I try to install the update it just restarts and then 2 minutes later I get the same notification of an update. It's an endless circle lol. I have tried smart cleaning twice and each time I check for a system update and I get the original notification and the endless loop begins again. Is there anything else I can do to update my device? I'm not keen on performing a factory reset or rooting my device if at all possible. Also I'm not with AT&T. I'm with an Australian carrier.
Many thanks

How to stop OTA updates and upgrades?

I have, apparently, one of those sw3's that will not accept the MM OTA so that the watch will work after is successfully installs. I am having to reinstall the LCA43 ROM in order to get the watch to work. While I would like to have MM, I can't seem to find the right ROM to install and XC is no help in either the software repair or update. The issue is when MM is on the watch, it continually stops at the 4 dots or symbols and never goes any further. I am using Ubuntu to connect to the watch for repair.
Is there a way to stop the OTA updates while still being connected to the phone via BT? I was happy to get this watch going again, but was disappointed this morning when it tried to boot in MM without me installing it.
Edit: This may be resolved. I installed a different ROM yesterday, 5.1.1.2, and it did not automatically try to upgrade last night so I may be good to go.

Factory reset on a corrupted Android OS?

So about a few years ago, I tried to root my galaxy note 4 (n910aucu2doi3), but I guess it rejected the root because it instantly bricked my phone, to the point where I had to completely wipe it using android recovery. The only way to get my operating system back was to download it online and install it through my PC (I had to find the exact version for my phone as well, 5.1.1 at the time, because it rejected every single other version).
Everything seemed to be working fine, except that I couldn't install software updates on my phone anymore. It was permanently stuck on 5.1.1. It was a bit of an annoyance but I didn't think much of it at the time.
Fast forward to now, and I'm getting several signs that my OS may be corrupted. My phone is constantly freezing, crashing and restarting. Maneuvering through applications causes the phone to freeze for a few seconds before either restarting or crashing the app. I want to say it's definitely a software issue, but I did install a new battery recently and it was working fine for a few weeks, could that be the issue?
If not, I want to start over, but I'm not sure how, and I don't know if it's safe to do a factory reset on this OS. Is there anyway I can get a fresh stock version of an android OS that can also update?
Any help is appreciated, I'm pretty much desperate.
I manually updated to 6.0.1 with the help of this thread https://forum.xda-developers.com/note-4-att/general/updates-thread-t3663943
It seems to have fixed the issues so far, and my phone can automatically update again

Bootloop for no apparent reason?

Hey, I have a question.
I've encountered something kind of strange with this device. I've been running Android P with the December 2018 security patch, rooted with Magisk. I've never encountered any problems with it so far except for a few bootloops I've got for deleting some modules in Magisk.
One day I decided to restart my phone because it was kind of laggy and so far so good it was booting. It showed me the Xiaomi logo and then it asked for the pattern to start Android. I entered the pattern and it just got into bootloop. (I've gotten bootloops before but it never got to the point where it shows me the logo and asks for pattern). I don't know what caused the bootloop because lately I haven't been messing with Magisk. However I thought it was a good idea to get into recovery and factory reset it (this has gotten me out of bootloops before so I gave it a try). After the reset it started to bootloop again, I just restarted it and it worked out just fine. I set up my phone, obviously root was gone because of the reset but I realized my phone's gotten updated to the March 2019 security patch. This was quite a surprise because I've been trying to update it and nothing seemed to work. (I tried updating it once by reflashing the original firmware with MiFlash, it was version 10.0.2.0, and before rooting it to install the security updates, they were just failing for no reason because there was no root on the phone).
So do you guys have any idea why my phone got into bootloop out of a sudden? And also why did the update successfully got installed after the factory reset?
