This is how I downgraded from Pie to Oreo. I can't guarantee it works for everyone but it worked for me. It required an SD card and a computer.
This is not a guide for the android development savy users but for people who preferred oreo to pie. It works without an unlocked bootloader and an unrooted phone. You will have to wipe your data so backup everything beforehand!
STEP 0) Remove your google account from your phone so you can prevent it automatically updating to Pie on first boot. Go to Settings > Accounts and remove your google account from the phone.
1) First download the zips that include Oreo with the November security patch and the December security update. Put these in the root of the SD card and rename them so you remember which is which.
I have found November Oreo links for both TA1012 and TA1004 but reportedly they both work for all Nokia 8 phones as the main payload.bin file is the same. I used the TA1012 zip with my TA1012 phone.

Don't worry about the TA-1004 stuff, all Nokia 8 software is generic, only google makes a difference between the model IDs.

2) Boot into recovery mode.
a) To do this on Pie, plug your phone into a computer and wait for the drivers to get installed. Windows 7 downloaded a few megabytes from windows update for this.
b) Unplug your phone and turn it off. Hold Volume up and plug your phone into your computer. Keeping holding volume up.
c) When the sad android appears with 'No command' showing, release Vol+. Hold the power button and press Vol+ to get into the recovery menu.
3) Use the Vol+ and Vol- to navigate down to 'Apply Update From SD card' click the power button to select it. In the next menu select the November Oreo zip file. It'll then verify the downloaded zip and install it. This takes a few minutes.
4) Select Wipe data/factory reset from the recovery menu. You need to do this cause data created on Pie doesn't work on Oreo.
6) Repeat steps 3 & 4 for the December security update. I don't know whether you need to factory reset both times but it shouldn't do any harm.
5) Finally select Reboot system now and it'll boot into Oreo. This takes a few minutes.
6) Don't connect to any wifi during setup. Go to settings > system > about phone. Tap the build number at the bottom until you unlock developer options. Go to settings > system > developer options and disable Automatic system Updates.
Hopefully this helps someone. Thanks to @THMSP, @TeddyBeers and @al mak for various posts that helped me downgrade and write this guide.
That's exactly the way to do it.
Actually works both ways as upgrade or downgrade, as Nokia kindly provides full rom oreo/pie instead of just incremental update.

Setup updates from Android 8 back to Android 9 Again
Useful guide, thanks, but after downgrading from Pie to Oreo how do you avoid being forced to upgrade to Pie again in setup, after you Wipe data/factory reset the phone?
I downgraded back to Oreo from Pie, but when I restart in setup I get forced to search for updates and it finds, downloads and installs the Pie update again, and I dont seem to be able to avoid it?
Disable in Developer Options

You have to enable Developer Options then disable Automatic system updates. You will always get the notification that a system update is available but it will not download automatically. Going further, you can even turn this notification off and forget about it.
The problem is that it happens before you get to a point where I know how to access the developer menu to do that.
It happens during the setup wizard, which I can't see how to complete without selecting a wifi network or mobile network, it then searches for downloads and installs the update before it sets up the phone and drops me at the home screen.

I've been having the same issue. I think it is new. I've done the process as early as January 9th with no forced update. As of yesterday it is forced. I've posted my experience in the thread for NOST. Pie may be life now because there are no custom ROMs and I expect all Oreo ROMs to have the force update thing inside them.

Not as far as I am aware, though it might be needed if you are booting into recovery mode bia adb.
@nb111 @hodiedodie
Is it possible to either get through the entire setup without connecting to any network - you will have to forgo logging into a google account at first. Or only use mobile data in the hopes that google is smart enough to realise that people don't want to download 1.5GB on their data plans?

I doubt I'll do this myself but I would suggest doing a man in the middle attack on the phone with arpspoof in a Linux distro. Use Wireshark to see what servers it calls out to. Then I would go in my home WiFi router and block those IP addresses. Then reset the phone and connect to the WiFi network and see if that works.
Ok solved this one, had to Update to P remove the Google Account linked to the Device and downgrade again.
It's Part of the Factory Reset Protection that you cant skip the Wifi and Update Screens.

I didn't try out dua sim because i have only 1 sim and it works well . don't worry bro, any problem can be solved as long as you done downgrade，it's easy to unlock BootLoader under Oreo ，so you can flash your original official firmware use OST tool or NOST in case any issue . （i downloaded my TA 1052 firmware from google，but i didn't flash it because this 1004 so far no problem）
i downgraded because my battery drained very fast and phone became hot frequently ，but i cant find any other way to downgrade or unlock BootLoader under Pie ，the official unlocking method doesn't working with Pie. i unlock it successful after downgrading by flash this 1004 stuff .
There's a small surprise when flash 1004 firmware，it's showing failed:'version old ，not support downgrade' or something i dont remember，my phone off and stucked at starting log and can restart even holding power button 1 minute，so i thought it fu*ked and bricked，after some time i tried hold power and volume + button finally it switched off and in recovery mode i did factory reset and restart ，Oh sh*t ....... it's Oreo already ！！!

Force shutdown the phone by keeping volume up, volume down and power pressed for some time (2 - 3 minutes). Then directly boot into recovery by holding down volume up while connecting the phone to the PC via. USB.

I successfully rolled back to Oreo.
I wonder if removing the Google account before the rollback prevent you from rollback - install the forced updates - rollback again (I had to do it because I was forced to install the updates the first time, while the second one I had the possibility to skip the configuration)

Hi everyone,
As many of us know experimenting with stock roms and installing custom roms can lead to many problems, such as boot loops, random restarts, stuck on boot animation etc..
It happened to me, so here is the solution:
1. Power off the device
2. Download the Alcatel Mobile Upgrade app, you can find it on Alcatel site since I can't yet post links
3. Connect your device with USB to your PC while its off.
4. Wait until the battery icon disappears, and then press the both Volume up and Volume down button + Power button.
5. Now the screen will turn red.
6. Open the Mobile Upgrade app and select 6045(5.5) or 6039(4.7) respectivley.
7. Now just click next all the way until the button turns to Download.
8. Long press the volume up button until it vibrates then release.
9. Now press the download button and wait until the process completes.
NOTE: It will take a while since the Alcatel servers are quite slow, in my case it took 3+ hours, but hey it does the job!
Good luck and Cheers!

You're most welcome, happy modding.
I don't know if things have changed with Mobile Q, but this sw is janky JUNK.
If I attempt to update while off, it starts when identifying sw version and either craps out connecting to their server or tells me 'there is no greater' i.e. I'm running latest already (which I'm not as OTA is waiting to install). Choose Upgrade anyway after getting phone back off (or download mode) and rinse/repeat. If one didn't turn back off (or download mode), then it would just balk that it can't identify phone (that it just identified to tell me the phone is up to date (which it's not). It's like a mindless loop of step 3. :silly:
Just did chainfire full unroot and wanted to get last update the easiest way.
Maybe it's because phone downloaded latest update OTA, but have as of yet to install (because I didn't want boot loop due to recovery.img
The LGMobile support tool is so much better...
Now that I removed root, how in f-k do I even get back into TWRP.
---------- Post added at 11:42 AM ---------- Previous post was at 10:56 AM ----------
tried again after factory reset, then download mode (funny that's a blank screen after red screen long press vol up). PoS reboots when checking server for latest sw, then
'there is no greater software version available to ugprade your phone,actual version of your phone is the latest.

Thank you so very much for this.... Alcatel says nothing about booting into Download mode... this did the trick!
Was enjoying the Cyanogen Mod ROM and TWRP, until my phone was blown off a table and cracked the screen just above the USB port... So glad I bought the insurance, but it would have been null and void if still rooted and customized....
Making certain it's completely factory, and slogging up to Cricket tomorrow at 11 to get it replaced, then back to where I originally had this one....
You've saved my butt, and I'm eternally grateful!
(BTW, my PC is running Win10 Pro 64 and the 4.9..2 Mobile Upgrade works like a champ!)
You're welcome, glad it was useful and as always have fun!

sorry for my question : does this method relock the bootloader too ?
I mean: after install, the phone will be full-stock ?

If you had USB debugging enabled you could flash the TWRP recovery and create a backup of your data then reset the phone and restore the data.
Hello there ,
I will soon acquire a Galaxy S7 after having spent 2 years on a Nexus 5X that I loved (despite its ridiculous 16Gb storage and weak battery). I used to install custom roms on it with TWRP but I never had the will to root it and go further.
Every tutorial I find online explaining how to install TWRP on the Galaxy S7 with Odin finish with the S7 being rooted. ... Is it compulsary? I mean, can't I just install a custom rom (i.e. SlimRoms or Lineage) without the smartphone being rooted, just with TWRP installed?
I just want to make sure before trying and failing like an idiot But if it works the same as on the nexus 5X, I just need TWRP to install a custom rom that doesn't need root access.
Thanks a lot, have a great day!

Yes ofcourse. Today I had issue with mount /data etc after full reflash stock via Odin, check HERE. And I didn't rooted device before flash TWRP. I just did like that:
1.Flash latest full stock with Nand Erase and RePartition option (and PIT file) and BL update.
2.Now you need force go to stock recovery menu, but after first reboot thats is automaticly so wait till just "erasing..." finish and thats it, then while second reboot you must force to stock recovery (just hold three buttons combo directly after you will see Samsung logo).
3.Format cache, then format data and power off phone (if you stuck on "no command" just press few times Vol+, Vol-, Home Button) and thats it... menu will shows up).
4.Force to download mode (three buttons combo but with Vol-).
5.Flash TWRP via Odin3.
6.Force go to TWRP directly while first reboot and format all partitions.
7.Thats it - enjoy all custom ROM's
And thats also way to solve issue with mounting /data (encryption issue).

uff, sorry no offense, but now I don't know if I would dare to install TWRP with these hints So, you mean one should do so when having hardware issues? Anyways, usually it would be that easy as the developer of TWRP describes it:

Note: "If you have a G935P, G935V, G935R, or G935A (aka the US Snapdragon models) your bootloader is locked. I will not be making TWRP for your device - it simply cannot happen. Sorry."

Buildnumber (latest build): NRD90M.G935FXXS1DQHM [Baseband: G935FXXU1DQD7]
[x] Check if OEM is unlocked (see Developer Options)
[x] Saving latest SuperSU[*****] zip file to external SDcard
[x] Wipe data/factory reset via stock recovery (press "power off" button to select respective entry!)
[x] Power off phone and start Download mode for flashing Auto-Root[***] through Odin3[**]
[x] Waiting more than 10 minutes :crying:
[x] Tried to flash back to an older firmware as I haven't download the lastest one to my PC, now I have a bootloop :crying:
[x] Flashed older firmware again by selecting "Nand Erase", "Re-Partition" and "Phone Bootloader Update" without choosing HOME_CSC file this time (thanks to your guide^^)
[x] Flashed latest firmware (see above-mentioned buildnumber) and did a factory reset (plus wipe cache partition). Started Android OS to review OEM unlocking option (>> wasn't necessary). Factory reset again. Flashed Auto-Root again. Waiting 9 Minutes. Flashed bootloader and recovery file provided by chainfire as it seems like it really does not work this way. Guess there is something wrong with chainfire's stuff. Maybe I need to disable autodetection option when generating Auto-Root file for my device. Waiting another 13 Minutes. Flashed the whole firmware again. Thank you chainfire for making me hopeless
[ ] Flashing latest TWRP[****]
[ ] Without leaving TWRP flash latest SuperSU[*****] to prevent boot loops
I gonna download latest android build tomorrow and do all the steps again. Frankly, I already gave up mentally but maybe I will change my mind. To make things clear: I read your guide and also noticed what you have written about "How to update your phone to lastest stock firmware with CSC of your country?" but still can't believe why all these things are that complicated. Why do you recommend to "Nand Erase", "Re-Partition" and "Phone Bootloader Update" to be enabled during firmware update? I thought a factory reset would be good enough. So far as I recall I've never done that like this before

How to enter Recovery Mode / Download mode after powering off your device:
RM = press and hold Power Key, Volume Up and Home >>>> Wait until the upcoming error message "no command" disappears!
DM = press and hold Power Key, Volume Down and Home
(B) Developer Options: How to unlock bootloader
1. Launch the Settings app from the app drawer or the notifications shade.
2. Swipe all the way down and tap on "About device" and "Software info".
3. Tap "Build number" till you see a prompt on the display stating "You are now a developer".
5. Now go back to the main Settings page, scroll down once more and tap to "Developer Options".
6. Enable "OEM unlocking" (=Allow the bootloader to be unlocked)
(C) Where should I enter Auto-Root files in Odin3?

this content is hidden on purpose because it has actually nothing to do with the important part of my activities. I've found this picture through google pictures. My phone is still G935F. As I don't do all this for my first time I certainly would never consider choosing a file which is not belonging to my device
By the way, I've updated my last post: It all did not work for me. Hoping someone could still help me

Saying "Waiting more than 10 minutes" or having a boot loop is considered to be a guide? "What I have done so far:" is right above this "guide". Those mentioned tips are not meant to be a full guidance. It was meant to help others who have the same issues. I am really not the only one here who probably need help. That's why I gave some hints. Like I said: "To make things clear: I read your guide" even several times and I don't get what I was doing wrong! That's why I WAS here. I would NOT bother everyone or read guides over and over again, EVEN wasting my time by watching respective youtube videos, reading respective android articles or another "xda guide" showing me how to brick my phone step by step. Sorry, but this is not how it works for me - this time. And sorry again, please let me repeat myself: I don't understand what I was doing wrong, even with your guide. Plus like I said: "As I don't do all this for my first time" (not with this phone obviously) I really needed serious help! I wouldn't read your guides if I don't, right? I appreciated your patience and thank you for your help, but for now: "Frankly, I already gave up mentally but maybe I will change my mind". I am still curious to know what I was doing wrong but I need a break and will try to find someone else someday who really would love to help me by just telling me what I was doing wrong. Thank you for your attention! Have a good day! :good:
rifek4 said:
If you saying like that I cannot help you with anything and anybody other also won't. That's all. Good luck.
P.s. If you would like to do ONLY THAT WHAT IS IN MY GUIDE but exactly step by step you will solve your problem doesn't matter what problem is that and everything must works perfectly . But if you don't believe in it and you carry about broken you phone but another guides you using... then Really I cannot help if you know it better. Maybe better just stay on stock...

Oh, nevermind, one of the xda community helped me solving the problem^^ My phone is finally rooted.
PS: Like I said, I've read your guide. That means I've done everything what you were describing but it really did not work for me. The problem was I was using a wrong file. There was just a little difference between some files I've overlooked (I've mixed up s7 with s7 edge). It was just all about my lack of attention. You did probably nothing wrong with your guide but your guide really could NOT help me, I am sorry but still appreciate your effort. So, we were wasting our time by just repeating statements over and over again instead of just listening and asking. but I am still thankful for that haha. Good bye and have a great day!
Great to hear you are sorted. Would you care to share your solution on a new thread?
Thanks.

Remember: Your phones needs to be equipped with an Exynos Chip!
I'm surprised no one has given a proper thread for this, but then again, it may be because it's relatively simple to do.
Hit the LIKE (UP) button if this helped!
<<<<<<<<<<<<<<<<<<<<<<< >>>>>>>>>>>>>>>>>>>>>>>>>>
For starters: you do everything here on your on accord, and if anything happens to your phone, you accept the responsibility.
If your phone is not bootloader unlocked/rooted/etc, it should automatically receive updates when you check in your system settings.
NOTE: Doing this firmware update may break your root or cause rooted functions to misbehave. VERIFY THIS YOURSELF.
<<<<<<<<<<<<<<<<<<<<<<< >>>>>>>>>>>>>>>>>>>>>>>>>>
Steps (if your phone is boot loader unlocked):
1) Download the appropriate firmware from Asus' own website: https://www.asus.com/Phone/ROG-Phone/HelpDesk_BIOS/
- Determine if your phone is the WW (global) version, or the CN version.
- File is approximately 2 gb
- Put the file on your phone's ROOT folder (Internal memory, and not in any folder so the phone can detect it)
2) Once it is properly downloaded and placed, you should see the file there in .ZIP format. You can verify with using any file browsing app.
3) Make sure that your phone is charged fully and ready to update (backup your documents/pics/messages/etc.)
4) Restart your phone by holding the power button and select (RESTART)
5) Once your phone reboots, you should see a notification automatically pop up indicating that there is a firmware update available. Click on it and accept the update. Phone will now update and do the rest, do not shut down or do anything else with the phone besides perhaps leaving it charged.
- Takes about 10 minutes to update
- Once it reboots it will sort out your apps
6) FINISHED. :good:
I tried this and it failed to update. I did a factory reset to no avail. Please advise.
Ahhh thank you! I wasn't able to sideload upgrade from O to P... this method got me to P

This guide is for the first edition of the ROG phone
*Note: Only tested with Pocophone F1 Global ROM, but might work with other Xiaomi phones since I used a xiaomi flashing tool.
This guide is intended for users who have not made any modifications requiring superuser priveleges.
Simply put, plain stock ROM.
This will or will not erase your data depending on the issue. (I had to erase mine though.)
This Guide is for users who have:
Boot Looped Pocophone F1
LOCKED bootloader
USB debugging OFF
Stock Recovery
My phone got into bootloop because I accidentally changed the DPI to 1000 ("Smallest Width" setting in Developer Options), which worked before, but was bugged in MIUI 11.
(full thread about this here: https://forum.xda-developers.com/poco-f1/help/help-pocophone-f1-t4084113)
This solution is only proven working for DPI bootloop in Pocophone F1. I think it might work on other units and other bootloop issues as well, since this process just flashes your phone to stock rom even with bootloader locked and USB debugging off.
Requirements:
1. Google account linked with the phone
2. Mi Account binded to devices
3. Stock Recovery (Mi-Recovery 3.0) ("Vol+" + "Power")
4. MiFlash Pro
5. Stock ROM
6. Steady Internet connection
Step 1. Download and install 15 seconds ADB installer by Snoop05.: https://forum.xda-developers.com/showthread.php?t=2588979
Step 2. Download MiFlash Pro: https://xiaomiwiki.github.io/wiki/Tools_for_Xiaomi_devices.html#xiaomiadb-by-francesco-tescari
It is preferred to Run the tool as administrator to not encounter any problems.
After installation, MiFlash Pro as admin.
Step 3. Get your official stock rom using MiFlash Pro. It has a ROM downloader built-in. There will be two search results for each version of your rom. Choose the one stated as RECOVERY. See image below for reference. I chose the latest rom because it is also the MIUI version I am currently using before bootloop. I read somewhere that downgrading bricks your phone.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Step 4. Boot into Recovery Mode.
Press VOL+ and POWER buttons simultaneously. If your phone is bootlooping, just press VOL+ and it will go to recovery.
Select "Connect to MIAssistant"
Go to MiFlash Pro, click refresh. If IMEIs appeared, that means your phone is now detected. You can choose to Wipe Userdata first or Flash now.
Do not erase google account. I am not sure what will happen if you do, since FRP might need it.
a. Press Wipe User Data
Wait for process to finish.
b. Click Flash
*If Flash fails, click the button repeatedly until it works (This worked in my case.)
*Sometimes after pressing Wipe User Data, it automatically starts flashing as well.
Step 5. After finish flashing, your phone will boot up.
*In my first try I did not wipe userdata. The bootloop still persisted. So I really had to wipe userdata.
a. Connect to a network
b. Verify your Mi Account
c. If it asks for a PIN, it most likely won't work even if you know your pincode previously. (This happened to me)
-So you choose to log in to google account previously used instead.
Step 6. After this, your phone should boot up now. Cheers!
I recommend you to unlock your bootloader now and also to install custom recovery. That's what I did to no longer go through this hassle. I hope this guide serves it's purpose.
hey buddy.. i am going through the same problem...
BUT I DONT WANT TO LOOSE MY DATA.
I messed up with minimum screen width value in developers options on POCO F1.
It was 391 for my device and by mistake I did change to 3920 or something.
Which resulted to a complete black screen. This is the point where I sensed that I have messed up with that setting and tried to reboot my phone when I saw that the reboot, power off, etc options' buttons turned so so so much tiny that you barely can see them, and I could have missed them if I wasn't looking for the same.
Following that reboot attempt my phone is now stuck in boot loop.
It is getting rebooted continuously and automatically to recovery mode after showing the Poco logo..
1)The can be detected when connected to the laptop and
2)it is not unlocked.
Please help me out to get my phone working again.
And
I don't want to loose my data.
I DONT WANT TO LOOSE MY DATA.
I DONT WANT TO LOOSE MY DATA.
Please if there is any way to back up my data in this state and then flash the rom by your method.
and just a question that
Why does not MiFlash tools provide any option to recover or back up data before flashing a device?
Thank you.

Hi VIJAY,
This actually is the only solution I have come up after trying also not to lose my data. I made this guide for people who also encountered the same issue, since there was no guide for it yet.
In my case, since there was no way of backing up data, I just started finding way just to get my phone back and running again.

Hey there. This actually happened to me as well. I just retried to wipe it again, and somehow it wiped the data after several tries.
Also in case you might ask, I didn't wipe my phone from stock recovery. I only wiped it from MiFlash Pro.

Not quite sure on this one since i got bootloop whole on stock rom.
But this method just flashes stock rom on your phone.
My poco f1 is on MIUI 11 can I go back to 10 stable with this way ?. I'm newbie and noob. Thanks.
Hello!!
Mine Device doesn't get any OTA, it always shows that "No updates available ".
I'm currently running on MIUI 10.9.6.27.
I want to Upgrade to MIUI 12.
How could i do it ??
I tried to flash MIUI12 Rom but it throws error.
It says "Looks like current Android version is different from that in the recovery package"

2. LOCKED bootloader
3. USB debugging OFF
4. Stock Recovery
5. Wiped User Data: the data on my Pocophone has been wiped out
Buddy, i follow the steps in your guide, but i got stuck at step 4...
Because my phone was bootlooped, I only pressed the VOL + button in about 15 seconds....then the screen goes blank (no logo, just black screen)...
...So, I can't select "Connect to MIAssistant".:crying::crying::crying:
Then... I checked out via cmd (adb)... the messages appeared...
C:\adb>adb devices

Not waiting for long... then I go to the next step...

Same like above! Any solution?
So I was fed up with Xiaomi latest updates on this Phone Mi A2 lite and decided to give it a go to downgrade to android 8.1 back when this phone was A REAL BEAST!
Guess what happened. Firstly there was no mobile network so I flashed again with android 10 modem.img and everything was looking fine the phone was snappy, blazingly fast then i noticed that video camera could not record normal video only short,slow motion and timelapse videos. When it was with android 8 original modem this was not happening. So after reading some stuff here on XDA I tried to flash modem.img of the first ever fastboot rom available for mi a2 lite. it was 9.6.4.0 and after i flashed that, i had mobile data doing just fine, tried the video recorder and everything was smooth.
During that time i enjoyed using my phone, I had oppened PES 2020 since morning that day, and when i tried to play at midnight before sleep it was still on the ram and I was like WOW thats fantastic.
Sadly after i went to sleep and i woke up I noticed the phone to be updated to android 9 pie. And i was frustrated because it was so great i completely forgot the part i was seeing to buy another fast phone. And yesterday I tried again with the same steps but even i had video not working, or i had not mobile network. I couldnt make it work. So if anyone knows how to make it happen please help.
Bugs that appeared since android 9 was not there in android 8.1
WIFI AND BLUETOOTH
I thought this was an hardware issue but no! Even if it still had some interference like from 43Mbps I got like38 Mbps with both on while on oreo but not like 43 with 4-8 Mbps on Pie or Android 10.
The only two things that on oreo wesre bad was that camera had no option for 60fps record and no FM Radio!
BUT I WOULD DO EVERYTHING TO GET OREO ONE MORE TIME WORKING
Oreo was the only smooth rom ever ya.. i guess when you try again,make sure auto update is off in developer settings

Try flashing in edl mode , in fastboot mode , fastboot command " fastboot oem edl". device will go black whit blinking led. in flashtool , device is com7 or something like that. Choose the Oreo rom you want and check "clean all"at the right bottom all your data will be wiped but bootloader remains unlocked.when you see "succes " your phone is flashed, keep the phone connected and press and hold power button till you see it boots ( about 20 sec.) Now go true boot-up wizard. Before installing apps etc... go to settings and enable developer options, by tapping buildnr several times. In dev. settings disable "automatic update" now your phone will stick to Oreo.
Thank you very much but i was able to do myself with some commands in twrp adb mode i found in a thread! This phone is a suppppeer beast now! I can keep this phone for another year with no problem at all! Its super smooth and snappy??

Can you share the steps you follow to downgrade it? Please! I'm really thinking about it, I miss having the apps in background for real.
Hello together, same for me. With the latest Android my A2 Lite is really crappy. Even freezes while using Chrome. Reading that there might be issues while downgrading I would appreciate if someone could support with a proper how-to.
Thanks

Fastboot flashing
1. Download desired Android One version from here: https://forum.xda-developers.com/mi-a2-lite/how-to/fastboot-xiaomi-mi-a2-fastboot-images-t3824871
2. Download platform tools from here: https://developer.android.com/studio/releases/platform-tools
3. Unpack Android One till you will have images folder and other files
4. Unpack platform tools and open it in CMD (you can do it by writing "cmd" in folder path)
5. Go into developer settings and turn on OEM unlocking and usb debugging
6. Boot your phone into fastboot mode (connect your phone to the pc and write "adb reboot bootloader)
7. Unlock bootloader by "fastboot oem unlock" command
8. Boot to fastboot again
9. Copy your android one path and paste it into adb and add /flash_all.bat and hit enter
a) flash_all.bat - installs android one and removes everything
b) flash_all_lock.bat - same as the one above but will also lock the bootloader (phone might not work after locking the bootloader)
c) flash_all_lock_crc.bat - lock bootloader and encrypts data
d) flash_all_except_storage.bat - flashes android one but doesn't remove any apps or reset setting (not recommended if downgrading or updating from 8 to 9 for example)
10. Once you finish configuring your device unlock developer settings and turn off automatic updates
Xiaomi Flash Tool
From point 1 to 8 it's the same
9. Download Xiaomi Flash Tool from here: https://www.xiaomiflash.com/
10. Unpack it and open it
11. Connect your phone to the computer
12. In the right bottom corner choose which one of .bat files you want to use
13. Boot to edl mode by "adb reboot edl" or "adb restart edl" (don't remember which one works)
14. Click flash and wait till it says "done" or "finish"
15. Disconnect your phone and hold power button for about 10s
16. Configure, disable automatic updates and enjoy
Personally I didn't notice any diffirence between flashing through fastboot and Flash Tool, but a lot of people recommend using flash tool to downgrade
Also I hope this guide is quite easy to understand
Edit: Also while configuring update will start downloading so just go to Updater and stop it
Thanks a lot, will try it via fastboot. But what about the issues with modem.img etc as mentioned during the downgrade from Q to Oreo?
For what i have read people normally flash and old android 8 rom, and then by recovery they update to the final build of oreo to solutionate errors

Oh yeah forgot that, to solve them I think you need to flash modem.img alone after flashing whole system, basically copy modem.img to platform tools, open it, boot to fastboot and write "fastboot flash modem modem.img". Not sure if that will work, but from what I remember it solves all issues
I managed to install android 8.1
Now i have everything working and the steps i followed are in the image!

14. Click flash and wait till it says "done" or "finish"
15. Disconnect your phone and hold power button for about 10s
16. Configure, disable automatic updates and enjoy
Personally I didn't notice any diffirence between flashing through fastboot and Flash Tool, but a lot of people recommend using flash tool to downgrade
Also I hope this guide is quite easy to understand
Edit: Also while configuring update will start downloading so just go to Updater and stop it

Finally I used the instruction as mentioned by Divolka (thanks again!) via Fastboot. First flashed 9.6.4.0 then 9.6.11.0 and immediately deactived the updates in the settings after setup.
Well currently everything seems to work fine, just SIM 1 and SIM 2 slots are switched and I only can use the current "SIM 2" slot with working mobile data etc. "SIM 1" slot is not working properly but I can live with that as I only use 1 SIM.
I hope there are no other bugs somewhere as I did not flash modem.img or anything else separate, just the full stock roms and locked the bootloader at the end again.

I have my phone running since 9 days since the day i flashed oreo, there isss noo problem! Its super great!
Only if you miss 60 fps recording and fm radio that were not available on android 8
Yes it is true, the speed of the phone is amazing compared to Android 10. But now I am facing battery issues phone does not go into deep sleep anymore, therefore battery lost almost 30% in half a day without using. In the settings I can only see that system / Android OS is the root cause but even the battery analitics apps can't tell me which app is the reason.
edit: according to BBS it is netmgr_wl what leads to the wakelocks so indeed related to the modem issue. Anyone has any advice? Should I flash the modem.img from the Android 10 Rom and if yes how?

Fastboot flashing
1. Download desired Android One version from here: https://forum.xda-developers.com/mi-a2-lite/how-to/fastboot-xiaomi-mi-a2-fastboot-images-t3824871
2. Download platform tools from here: https://developer.android.com/studio/releases/platform-tools
3. Unpack Android One till you will have images folder and other files
4. Unpack platform tools and open it in CMD (you can do it by writing "cmd" in folder path)
5. Go into developer settings and turn on OEM unlocking and usb debugging
6. Boot your phone into fastboot mode (connect your phone to the pc and write "adb reboot bootloader)
7. Unlock bootloader by "fastboot oem unlock" command
8. Boot to fastboot again
9. Copy your android one path and paste it into adb and add /flash_all.bat and hit enter
a) flash_all.bat - installs android one and removes everything
b) flash_all_lock.bat - same as the one above but will also lock the bootloader (phone might not work after locking the bootloader)
c) flash_all_lock_crc.bat - lock bootloader and encrypts data
d) flash_all_except_storage.bat - flashes android one but doesn't remove any apps or reset setting (not recommended if downgrading or updating from 8 to 9 for example)
10. Once you finish configuring your device unlock developer settings and turn off automatic updates
Xiaomi Flash Tool
From point 1 to 8 it's the same
9. Download Xiaomi Flash Tool from here: https://www.xiaomiflash.com/
10. Unpack it and open it
11. Connect your phone to the computer
12. In the right bottom corner choose which one of .bat files you want to use
13. Boot to edl mode by "adb reboot edl" or "adb restart edl" (don't remember which one works)
14. Click flash and wait till it says "done" or "finish"
15. Disconnect your phone and hold power button for about 10s

Do you know how to do this steps on Ubuntu? The Flash Tool looks like it's only for WIndows

I am not having any battery issues with the method I followed, do not know if that is the reason or not. And I am having the best battery life i have ever had on this phone with android 8.1.
I am playing hard with my phone and it still gets 6+ screen on time. Without playing pes 2020 i get 8-10+ screen on time
EDIT: I keep bluetooth Always On to be connected with my mi band 3. Because before i couldnt use it with wifi turned on because we all know what it does to internet speed

Finally I tried some other instructions but none worked. I followed your instruction eith 9.6.11.0 and now I can confirm it also works perfectly for me at the moment.
Can't give any long term results yet but at least no network issues anymore, no SIM swap, everything is fast and stays in RAM, and seems that also thr battery is fine now.
So thanks again for the great hint Lucky again with this phone!
