Not recieving OTA. - Xiaomi Mi A2 / 6X Questions & Answers

Hello fellow MiA2 users! I have my MiA2 rooted with Magisk, I've been following the easy steps of unrooting, updating, rerooting to get every other OTA. I then stayed on the March 2019 update for a while and while trying to update it failed too many times, eventually leading for my phone being unable to find updates anymore. I'm on security patch level March 5, 2019 and whenever I check for update it reads "your system is up to date". Is there a place where I can find the files I could flash with fastboot to update my phone without wiping data?. What do you guys recommend me to do to keep my phone updated? Thanks!

Obviously you are unlocked, thus just fastboot-flash desired ROM (latest official is 10.0.13.0, see directly Xiaomi's c.mui.com or here) using "flash_all_except_data.bat" which does not re-flash stock dummy of /data, thus keeping your /data partition. In case you are still hesitating. you can fastboot-boot into TWRP (I prefer "4pda-edition") , make backup of /data and copy it to PC.

Issues with android security patch level

Hello everyone.
I`ve got rooted Nexus 6 with Franco kernel. From time to time it shows system security updates, which I install`s. But I notices on my android security patch level stops on January 2016 and still want to install February updates. Everytime N6 tries to install February updates. Does anybody know whats going on? Maybe it`s because I locked with security password on my twrp? After rebooting twrp show`s and I really dont know are updates installed well. I quess not. Can someone help?
And another question, does this android security updates will remove my root?

Security updates will not work; unless the device is completely stock.
You should look at installing the OTA from this page - instructions are provided. If you want to retain the kernel,TWRP & and root you'll have to re-flash them when you're finished.
https://developers.google.com/android/nexus/ota
If you're unencrypted (I'm not - I prefer the security to an extra 10 minutes of battery life) do some reading first - I'm not sure how the OTA works with an unencrypted device. Maybe other members can advise both of us on this point.
Thx for answer`s.
Correct me if I wrong, but I`ve got stock rom, but with Franco kernel, and root, but it`s still stock, right? Does this could be a reason? All my data are encrypted, so maybe this could be a reason ( however after every update reboot I decrypt`s my data), I`ll switch off encrypting my N6 and try again update it.
----------EDIT------------
Guess, NLBeev was right. I can`t make an OTA update when my N6 is rooted, only manually method. I really afraid of this manually updates, because of losing something from my phone, or even brick it.
fear is something that xda can not help you with. itll happen through out life, in many situations. the only thing that you can do is deal with it and move on.
I manually update mine every update and have yet to have an issue.
I f you're encrypted (good!) then my earlier concern is irrelevant. Sideload the newest OTA at the link I gave you. I've done it now several times with two Nexus 5s and a Nexus 6. It's quick and simple and doesn't touch your data.
But I still always take a TWRP backup first and copy it to my laptop. Can't be too careful...
Once again thanks for help! I`ll try install them manually, as fast as I make backup by twrp.
Ach, I forgot, last question, which update should I download? I`ve got January system security updates, so should I download every single one by one? Or just last one (July 6.0.1 (MOB30O))?
Regards!
By "manually' do you mean extracting the separate components (system, radio, boot...)? I strongly recommend the OTA sideload method. Fast and simple, with no data loss.
You need only do it once. Download the MOB30O OTA and sideload it. Then if you want you can flash TWRP and root.

What is the purpose of each of the 3 different update zip files ?

Hi,
Sorry of this is a bit of a newbie question but:
What is the purpose of each of the 3 different update zip files ?
And do I have to apply them all - and in what order ?
In my case, I am about to update to B389, and I have downloaded 3 files for VIE-L29C636B389 (currently on VIE-L29C636B130), and I have an update.zip, an update_full_VIE-L29_hw_spcseas.zip and an update_data_full_public.zip.
I was planning on doing the first two by the dload method (with reboots in between), but the update_data_full_public.zip doesn't appear to have an update.app, so how do I load that ? (I do have TWRP on my phone, so could probably figure it out - eventually).
Cheers,
SZ
same question
I read somewhere that it should be flashed in that exact order. i'm guessing that is the same procedure as with auto OTA updates, except now we have rooted phones, so bye-bye to auto updates. I am currently on VIE-L29CB636B387 and i received an automatic Huawei notification of a new version (VIE-L29CB636B388) about a week ago. I tried to update to that version in System Update-Quick Update, but that didn't work (surprise!). There was no issue though as when I rebooted it just went back to 387. However, I now have a red "New Version" notification in my System Update. Please tell me how your upgrade went if you went ahead and flashed 389. I have the three files already from filefinder, i also have TWRP and/or I could use adb fastboot to install. Thanks in advance.
Hey,
I am not sure I want to proceed on the basis of something that somebody 'read somewhere' ....
Anyhow - I've not run these updates yet, as I wanted to backup my phone first, but TWRP keeps blowing up with an error in the middle of the backup, so I am not going to try anything until I get to the bottom of that.
Will let you know if/when I ever go ahead!
Cheers,
SZ
Hi,
TWRP blowing up during NAND backups? thats not a good thing. Upon the advice of a forum member (xzanium) I flashed TWRP 3.1.1-1 instead of TWRP-3.2.1-0-vienna. No hitches so far, solid backups and no hiccups in flashing SuperSU, also got xposed to work seamlessly and other stuff. I hope you are able to resolve the issue you mentioned and get around to getting VIE-L29CB636B389 on your phone.
Well good luck to you, and post here any progress if you would.
SZ,
I have an idea on what the purpose of each of the 3 different update zip files are for and whether you have to apply them all - and in what order.
Since I could make a NAND backup using TWRP without issues, and there was an OTA update notice for an upgrade to VIE-L29CB636B388 which I couldn't upgrade to while rooted, I decided to unroot in order to upgrade to that. First i did the requisite steps - uninstalled the xposed framework and proceeded with the full unroot with SuperSU. Then I performed the dload method to flash the update.app that I extracted from the update.zip.
It was here where i hit a snag. What followed was, I found out that Huawei needs a verified stock rom, meaning it has to be a fullOTA-MF-PV in order that the bootloader could be relocked. So I tried my luck and downloaded the stock ROM VIE-L29C636B370 and flashed that. Success! From there, and several auto upgrades later I was back to L29C636B370. Reinstalling my Google account also locked back FRP. At this point i am full stock EMUI 5
Now, to answer your question. When I tried to upgrade to VIE-L29C636B388 via system update quick update. I only saw one file - update.zip therefore this must the only one needed for incremental patches. The same holds true with update_data_full_public.zip as I later learned when I decided to use the proxy upgrade method in MT filefinder . It applied a 2nd patch. The third file, namely, update_full_VIE-L29_hw_spcseas.zip was not required for this incremental update. In fact, the update process was cut short and an error message appeared that the file could not be located, even though i copied that to the HwOUC folder. It appears that this was deleted before the fullOTA update could finish during the incremental update process. Clearly, this last zip is not necessary for incremental updates. So this must be the package which delivers the rest of the ROM, or the parts of it that needs to be changed.
So, obviously what "I read somewhere" was legit. I hope that answers your question.
cheers!

Fixing failed OTAs after execution of TWRP

When booting TWRP using fastboot, without flashing it to the recovery partition, eg. "fastboot boot twrp-sanders-r20.img", only for the purpose of taking a partition backup, once done the device wont longer take OTA's!
That is IMHO a very unexpected behavior, as booting this way and keeping system read only should mean that nothing on the phone gets changed (well except the data partition if a backup is saved on these one).
One would expect this not to mess with the OTA process.
Now, this twrp at least: https://forum.xda-developers.com/moto-g5s-plus/development/recovery-twrp-3-1-1-r7-t3694910 does, after some investigation i found out that it is mounting the oem partition writable and modifying it adding a .twrp file to the root. Since the OTAs are checking and patching this partition of cause they will fail.
Luckily there is a way out, you can reflash the OEM partition for example from here: https://forum.xda-developers.com/moto-g5s-plus/how-to/tutorial-fhash-oreo-8-1-stock-global-t3852967
that is assuming that you are running the first Oreo 8.1 update, if you had an other version when the issue hit, you will need to find the right OEM partition image for you actual build.
IMHO this behavior of TWRP is unacceptable and should be fixed in a new release ASAP.

Agreed; received today a security update for my moto G5S plus (didn't root till i got the official 8.1 Oreo update) and every time i try to install takes me to TWRP and i keep it as READ ONLY (since TWRP itself says if u modify u won't b able to receive OTA updates) and... even without the modification i still can't get the update. this has to be fixed ASAP by TWRP
I did discover that if you keep the OTA files for older updates, you can re-run them to update the OEM partition. Unfortunately it only works one update generation.
I wonder if we just delete the .TWRP file if it can recover it. I'll test later this week. The OTA has a way to repair partitions

imho 99% sure, it still will fail, the partition does not just have to be semantically unchanged it must be 1:1 bit wise identical with what is expected.
I'll see what happens. I'm not a developer but I have pointed this out a few times to the developers of both TWRP threads, along with sharing these issues on the telegram group, but everyone else is focused on the latest custom ROM and doesn't care about stock, so the issues have fallen on deaf ears
in a nutshell how can i receive the last OTA security? do i revert to stock , install then root again? holy moly that's a lot of work

Unfortunately until they fix TWRP so it doesn't damage the OEM partition, you need a clean copy of the OEM partition to take the OTA.
However, there is a way you can prevent this, but it is a little hairy (you can't use any magisk modules). You can use the magisk app to patch the boot.img file that is from a slightly older Oreo firmware and flash that with fastboot, without using TWRP.

Yup. Just confirmed that deleting the .twrp file does not fix it.
I've reached out to Motorola to update their Lenovo Motorola Smart Assistant tool to support the official Oreo OTA which will allow us to download the latest full firmware file, which would give us the OEM partition to reflash before the next OTA.
I'll bother the TWRP devs again this week to get this unexpected behavior removed so we don't need to bother anyone in the future.
Update: none of the TWRP maintainers currently have replied to me about this issue.
@CheckYourScreen hasn't been active for a while but hasn't responded to a few different attempts to point this issue out (Been over a month since first notification with no acknowledgement)
@MasterAwesome has a custom TWRP that is latest, but they're still working on it. They're our best bet to possibly get it fixed since they're actively working on it. They've also been made aware, but no response yet (4 days since notifying and it was a weekend, so hopeful)
@GeneticEnginer was notified today. They developed the first unofficial TWRP (3.1.1) and might be able to help, but not holding my breath
I've also contacted a few people who do unofficial TWRP ports for some tips on unpacking one of our existing TWRP files and fixing it myself. It may be the way to go.
Hi guys. Final update. I've fixed TWRP temporarily. If we're not going to run custom ROMs, use this TWRP to backup. It does a bitwise backup of OEM and doesn't mount it as RW so it WILL work for restoring fully OTA capable stock ROM. It is NOT treble compatible as the treble compatible ones do weird things that I haven't documented.

Question PIXEL 5a Stable Build Available

If you haven't already, you should be receiving a notification that the Stable Android 12 or "S" Build is lurking in the shadows of your Pixel 5a handset. If you're currently on the (only) beta version we received OTA, your update won't inconvenience you for too long, as it weighs in at <4 mb, all in.

Attempted the upgrade last night, seems there's some new things required if you want to flash the modified boot image and successfully boot. I believe you need to wipe the data partition and also pass along a few flags during install. However, temp root is an option if you want to avoid that for now (I did) by simply booting the image in fastboot vs flashing it. Just FYI!
Edit. Sounds like SafetyNet won't pass yet if you do end up going the permanent route? I could be wrong but I believe that's what's I've read. I just checked on mine and the temporary boot image does seem to so that's good.
If you read this thread you will see how to do it, as done on beta releases. https://forum.xda-developers.com/t/guide-flash-magisk-on-android-12.4242959/ It is possible to achieve permanent root on 12 without wiping the personal data but it is a delicate dance. I have not tried it yet but as I understand it the process is to unroot 11 and at least remove Magisk modules, take the 12 update, boot into bootloader and use fastboot to remove boot verification and replace vbmeta.img, then flash patched boot.img, reboot and reinstall magisk. It seems there is a problem with just flashing the new factory image with the wipe option (-w) removed. Instead of fastboot flashing the patched boot.img it is also possible to directly patch the boot.img from Magisk while temporarily booted from the patched boot.img (via fastboot), again after removing the verification checks. It may be critical as to when the 5a is rebooted or not; it needs to have a normal reboot after the OTA upgrade in order to complete the upgrade, then boot to bootloader for fastboot operations. I am going to go back and make instructions for myself before proceeding, and will do a Titanium backup before doing anything else.
Edit: it appears that some have achieved permanent root and still passed the SafetyNet check. IIRC it was done through the OTA upgrade path but I need to check that. If you are willing to wipe your data then just installing the factory image and then doing the fastboot commands it might work but that is not clear. Too many attempts at root and SafetyNet failed while flailing so hard to know right now if there are good alternatives to OTA.

Thanks for the link. I downloaded the full Android 12 image, installed it, disabled verity and wiped my data via fastboot, then flashed the magisk-patched boot. Worked like a charm and safetynet passed after hiding Magisk and installing Riru and the universal-safetynet-fix.

I am hoping to avoid wiping data by taking the OTA and then rooting - I just need to find the time to backup and write down the process first. I knew that the update could be done directly with the factory image, then rooted, but that requires the data wipe. If I encounter a problem that is the fallback approach - then restore data with Titanium.
I don't mind wiping data once. But if I have to wipe data for each update just to root, I'll stay on 11 for now until there's a better way to root
Exactly.... I'll wait for a better way to upgrade and keep my root on 12
You don't "keep your root" on 11 updates; you unroot, take the OTA, then root again with a newly patched boot.img. And the data isn't wiped when moving to 12 if done through the OTA, just like 11 updates. If flashing a factory image the data is always wiped. What is different with 12 is that there is a verification of the boot.img and this has to be turned off (because the boot.img is patched), with a single fastboot command. It does appear to be sensitive to some details, so best to have a detailed procedure written down before starting the process. But those that have done it do not report a long or difficult process - just a finicky one.

I want to upgrade ota....but what do i have to do to achieve root without loosing files, setup, etc
No, I have not done it yet - oddly enough I have other things needing doing. The information needed to do it is in this thread: https://forum.xda-developers.com/t/guide-flash-magisk-on-android-12.4242959/ Unfortunately since it started during the 12 beta program, and there was a lot of trial and error, it is necessary to work through the long thread and sort out the process - which appears to be fairly simple (if inflexible).
When updating or upgrading there are always two paths to take: 1) take the OTA that is offered (after unrooting), or 2) flashing the full factory image. Generally speaking, OTAs are designed to keep the user data untouched [edit: not untouched but just converted where needed for the new system] and the factory image is intended to put the phone to factory condition (i.e. no user data present - starts from scratch). Updates (i.e. not upgrades between Android major versions) over-the-air (OTA) are replacing blocks of the stored image, which is very efficient, but requires a pristine stored image (hence the need to unroot to pass the check). Upgrades (new Android versions) seem to download the entire image, IIUC, and then clean up any data (like config files) that are not compatible with the new system. Sometimes the result has been less than perfect, although it is mostly reliable. Ultimately a factory image is the guarantee of getting a known good system, which can then be set up to the user's taste. Backing up user data (e.g. with Titanium Backup) and restoring can make this easier but again, config files from the previous system if restored on the new system can cause problems. Some people prefer to flash the factory image and reinstall the apps as new to get the highest confidence in the result. Most of us just take the OTA and trust the process, prepared to wipe config files or even flash the full factory image if there is a problem. Your choice.
After I write a procedure for myself, and successfully upgrade, I will post it.
So those of us that never rooted can just skip the unroot process and do the rest I assume?

That is the case. It seems that some with 12 beta got tripped up by not getting unrooting/removing Magisk and/or its modules right so that is one less thing to worry about. If you have never rooted then the OTA should work as expected. Rooting can be done in two ways, either by achieving a temporary root and using magisk to directly patch the boot.img, or by patching the boot.img and flashing it, right after removing verification and flashing the new vbmeta.img (in both cases). Of course you first have to unlock the bootloader and enable USB debug, install the Android tools on your computer (minimum version: you only need ADB and fastboot), and connect your computer to the phone with a USB cable. Again, refer to that thread or wait until I can write something up.

How do one remove verification?
I haven't been able to permanently root android 12 without wiping my data. I'm not talking about upgrading from 11 to 12. I'm talking about after installing 12, I still have my data. Any attempt to permanently root 12 causes errors unless I wipe my data. This was detailed quite a bit in the link you posted. Have you tried permanently rooting 12 and keeping your data?
As I said before, I have not had time to try the upgrade. Also, that thread has multiple conflicting posts which is why I know it will take time to go through and parse out what works and what doesn't. There are posts IIRC where root was achieved with data retained - but exactly how that was accomplished is not clear (or even if that really did happen). Since we have not had our phones for long there shouldn't be too much in data to lose, and there is always Titanium, so I will give it a go when I have time.
One of the things that I would like cleared up is if the way to 12 and root is to stop the OTA upgrade process at some point and remove verification and/or root before continuing, or possibly root fails because it is attempted before the upgrade is complete. IIRC the OTA has at least one reboot involved, with some processing after the reboot (probably fixing the data to be 12-compatible). Clearly if the upgrade can be done while retaining data and then successfully rooted then it must be done in a precise way; the lack of precise explanations of successful roots is very disappointing.
Edit: If it does turn out that data must be wiped every time 12 is rooted then that means backing up and restoring will be needed for each update, as well as unroot/root, and possibly removing verification each time. That would be a huge PITA. Let's hope that isn't so.

But at this point unless you are willing to wade through 14 [make that 16 and counting...] pages of posts it is better to wait until someone posts a good procedure. Anyone not familiar with flashing is liable to get into trouble and needing a factory flash. However good 12 is, it is not so good that we can't wait a bit.

Flashing Updates

Hey, just wondering if when flashing updates do I need to do them sequentially or can I skip to the most recent?
My Note 9 is stuck on Android 9 and security patch nov 2019, can't update the normal way or with smart switch.
One way to install updates is to download your latest firmware from Samfirmware then install it via Odin in PC. Flashing to the latest firmware AFAIK is allowed, skipping the previous older firmwares.
If you're previously rooted, it will remove the root.
Best to make a backup first of your important data to an external sd card or to your PC. Updating sometimes require the phone to do a factory reset to have a successful update.
