How to revert back from stable pie to oreo? - Xiaomi Mi A2 / 6X Questions & Answers

I updated to pie stable and now my WiFi doesn't turn on, Hotspot doesn't turn on, and fingerprint does not get enrolled at the last touch.
Any ideas how to revert back to Oreo?

Unlocked bootloader & unlocked critical ?
Install fastboot ROM with Miflash

Thanks a lot. But I fixed my issues today. Don't think I need to downgrade yet as everything is working fine now. Thanks for answering.

My WiFi and Hotspot didn't turn on at all and my MAC address got deleted. Now after two factory resets, it's working fine.
I know that WiFi and hotspot doesn't turn on together after the pie update. There's no fix to it as of now. I tried checking the developer options and there is something related to this. I tried enabling the option but it doesn't work.

[Q] WiFi problem with MIUI

Hello,
I have just flashed MIUI Gingerbread 2.4.20-RC3 to my GT-S5570, everything looks great, except WiFi, when I turn on WiFi, it says "Scanning" finds my WiFi and then "disconnected" and again shows "Scanning" for 1 sec and again "disconnected", what can I do?
WiFi Error
You need to revert to your old stock rom, because the drivers for WiFi aren't working. Same thing happened on my mobile phone, when I flashed it with the newer firmware. Didn't really find the solution to this problem, but solved it by going back to my old rom. Hope this helps.
You can also try typing this code into your phone: #*#*526#*#*
It might work for you.
Best of luck.

Thank you for reply.
It is working now, here is what I did: In phone settings I tried to change themes lock screen to other, but unfortunately not default lock screen was way too big (very big resolution) so I was not able to unlock my phone any more, once I found that I can do it pressing back+volume down, it helped to unlock, but MIUI was crashed and stopped working, so I had to wipe all data and cash, to reset default settings, after this, everything works great now.

the same thing was happening to me (on the same rom)>> "fixed" it by reseting the notebook-hot-spot (connectify) I use
[sometimes even a simple wi-fi turn on/off or rebooting the device would help too]
I'm posting this in order to prevent you from doing more drastic stuff :cyclops:

(FIX) VoLTE stopped working in latest MIUI stable/dev?

I had a Redmi 4x which when shipped had 8.2 MIUI version (Before some 3 months). That time I checked using Jio and VoLTE worked fine. Then, My mother was using it and now after certain auto updates it was on MIUI v8.5.4.0. I had ported her no to Jio (4G only network), and now VoLTE didn't work at all. I tried flashing Latest MM firmware. I even clean flashed MIUI9 Dev and even then VoLTE didn't work. Always IMS will not at all register (Checked via Phone info). I hence declared somehow Jio network block listed 4x (other countries models) but LTE used to work fine. Out of all hope, I tried Official RR with its own recommended FW and even then VoLTE was down..!! I even changed Device model (Redmi 4x to Redmi 4), still it was in vain. Even tried adding IMS in default AP. Some suggestion to Choose Home IMSI in SIM Toolkit will also not work because latest Jio SIM doesn't ship with SIM Toolkit option at all!!!
After full frustration and wasting one full day, I thought I should change the phone. But somehow suddenly it struck to try fastboot flash the oldest MIUI8 which device was booting initially. So after trying that, Voilaaaa! 1st time seeing VoLTE after long hours and late at night !!!
Somehow Now I flashed latest stable 8.5.4 MIUI and it also has VoLTE working. Even in custom ROMs VOLTE now is working. So yeah just to share my learning, to help people who are having tough time with VoLTE..! :highfive::highfive:

So I followed yr method & Yes i got my Volte back but now i'm stuck in Marshmallow and there's a bug with the screen auto rotate not functioning. I googled and found that many people who downgraded to MIUI 8 are facing this problem & there it was also written that wen they upgrade to MIUI 9 Nougat screen rotate functions are restored. So here's the thing me being from India need my Volte for Jio and after a long time finally got it to work...But if i upgrade to MIUI 9 Nougat i'm scared that i might lose my Volte again & have to start my previous process allover again starting with unlocking my bootloader as i have locked it while flashing it to MIUI 8. So my question to you is what did u mean when you said " Now I flashed latest stable 8.5.4 MIUI and it also has VoLTE working. " from here did u just did OTA update (coz i'm getting V8.5.2.0 MAMMIED Update via my updater app). Or did u use Fastboot flash to 8.5.4 MIUI .??
BTW I was thinking should i just download a update.zip of the latest stable global V9.2 Rom & flashed it via the Updater App using update package option.. skipping v8.5.2.0 & other minor Updates and just jump to the latest. Will i still have Volte working on my Phone if i update to MIUI 9.

Hi., I unlocked bootloader and I used fastboot method to go back to prev version. Once the volte worked, MIUI9 also got VoLTE working. So try clean flashing latest MiUi and VoLTE would still work...

By clean flashing do u mean fastboot method or update.zip recovery method.....
U see I'm confused as there are many forms of flashing so it fastboot method with miflash right!!.
Ok I will try to download this fastboot stable rom for miui 9.... let's see how it goes.
Thanks a lot...
Damn this phone really is high maintenance...

So I tried and guess what it didn't work. Volte is confirmed to be working only in marshmallow miui8 and as we try to jump to nougat miui9 volte just doesn't work. So i flashed back to marshmallow and then did ota update ( minor 350mb update) which is still Android 6 and volte still works now I get ota update for miui 9 but I'm not willing to jump the gun anymore......
Maybe if I do ota update to miui9 after getting volte maybe it could miraculously get it's volte back but having flashed the phone multiple times and since I need to use this phone I'm gonna stop here so we'll never know if volte is ever gonna work in miui9 via ota...
Btw even if I got volte back the gyro and screen rotation is not working both in the old marshmallow and in the recently updated ota marshmallow. So playing some gyro games and having the gallery to open pics in auto rotate is out of the question.
I even tried flashing persist.img via both fastboot and miflash method & while it didn't allow me to erase and write the persist.img even though my bootloader is unlocked in fastboot method. I did managed to flash it via miflash tool after editing some .bat files via notepad++ so that I only flash the persist.img and not the whole rom.
There's a whole tutorial about this too on Google and guess what again this methods didn't do anything and I have both gyro and auto rotate not functioning.
It will function in miui 9 but in that version we'll know that volte doesn't work so....
My only conclusion is that without Xiaomi dev patching it out there's just no way this bug can be solved by simple flashing as in either form of the OS one ends up sacrificing one function or the other.
Btw thanks for replying, helping and hearing me out...
Really appreciate it.

This whole VoLTE concept more or less isnt as reliable as legacy 2g/3G calls. Even yesterday for some wierd reason, VoLTE in this phone didn't work. I swapped SIM to another VoLTE where it didn't work on it too. I just let it for half day after which it started working. There isn't one proper way when on rooted phones, to easily get VoLTE related log data, so that we can try fixing the rootcause. Anyways I'm glad somehow you are able to manage...
My Volte working with miui 9 stable roms
Pliz give detailed description.
I'm excited to hear about this.
Btw no offence but you are sure that yr device is Redmi 4X and not Redmi 4, right!!
try to change your location in additional setting from your system location to another location, ex: thailand, and then check your volte setting
Ok that thought never occurred to me but I will not go back to miui 9 for the time being but if I do in the future I will definitely apply this method to check the volte.
Thanks for sharing this idea
Is volte working for any of you in pie roms?
Not Working
I got my redmi 4x from china ;-; works on marshmallow and goes off in nougat (miui) , Custom ROM (all nougat roms works fine with volte) but no volte in Oreo as well as in Pie.. Maybe Locked Bands
Same for me.

Volte never worked for me on custom roms( oreo or pie). Currently on Arrow os (Pie). Tired everything but never got Volte working. It would be great relief for me if i would see volte sign on custom rom.

Wi-Fi tethering?

Hello I have a Razer Phone 2 on AT&T that I just unlocked the bootloader, installed TWRP, magisk and Arter97 kernel. Everything is working great, except for Wi-Fi tethering. I can switch it on but anything that connects to it reports no internet.
Any ideas what could be causing it? I've seen quite a few people complain about Wi-Fi issues with Arter97's kernel, could that be the cause?
I kinda want to install a custom rom but I just got everything set up to be my daily driver so I'm not in a hurry to go through the process of backing up all of my stuff again.
If you can provide any help, suggestions or advice I'd appreciate it!
MobileJAD.
Try toggling mobile data off then on with the tethering enabled as a workaround.
Sent from my Phone 2 using Tapatalk
Tried turning on Wi-Fi tethering, turning mobile data off and back on, devices connected to my tethering still unable to connect to the internet.
Had the same issue, for me it was fixed by reflashing stock rom then going back to custom kernel again.

Did you try this? https://forum.xda-developers.com/razer-phone-2/how-to/how-enable-tethering-root-required-t3911163
It worked! All that was needed was to simply toggle and enable the tethering feature! My only problem was that I he no idea about this buildprop. Thank you so much! Now my Razer Phone 2 is all set to be my daily driver!

Worse WIFI on MiA2 - Keeps disconnecting every 5 min

Hey guys,
Just got my relatives MiA2 temporarily due to my primary phone spoiling.
The phone is good but the wifi is so bad. I am sitting besides the router but still keeps disconnecting.
Is there any fix to this?
I am on stock Android 10, non rooted and locked bootloader.
Thinking of flashing a custom ROM to solve this and get a little more customization on the device
Will unlocking bootloader and flashing custom ROM like Blissrom solve this issue?
Any help will be greatly appreciated

XZ3 wifi problems

I'm just having a lot of problems withmy xperia xZ3 (H9394). In Monday, I updated google services and after that, the phone didn't connect to wifi or mobile data. I make a factory reset but it didn't work. I assumed the problem came from that update and everything will be fixed if I downgraded firmware. I tried first with sony emma flashtool, but I needed the bootload of my device to be unlocked. I unlocked it (yes, I screwed it) but emma said "no available services matched", so I tried it with newflasher and downgraded firmware, but it stayed in bootloop. So, I return to original firmware (52.1.A.3.92-R4C). It boot normally, but I have the same issues with wifi and mobile data, sometimes it works, but connects and disconnects constantly.
Someone can say me what can I do? I know that I can't relock bootloader.
@MartinX3 I know that you are a master, colud you help me?
Thanks! <3
I would look if that problem is the same on a custom ROM. (But flash on both slots and boot the latest stock first until you reach the desktop)
Or if it only happens with a specific WiFi, maybe the router need updates or a fix.

What did you mean with flash both slots?

Hello. I flashed again with 52.1.A.3.92-R4C custom Taiwan downloaded from xperifirm and it work for a time. First, I didn't have any issue with wifi and had 4G signal, but after hours, the problems came again and lost mobile and wifi signals. At that moment, I couldn't even activate wifi, when I turned it on it turned off immediately. For some reason, I activated airplane mode and turn on wifi and it worked, but when I turn off airplane mode, lost wifi signal. It's very strange. I think it's some problem with mobile data or something.
I will flash A/B slots. For that, I need the GSI and ASOP (Android 10.0 – Kernel 4.14 – Tama) img and I must do it with platform-tool, right? I don't need a firmware in tft?
Thanks.

For the custom ROMs you need to have the latest firmware on both slots and booted once until you reach your apps.
Then just follow the instructions of the XDA threads and don't forget a fullwipe.

Hello again. I downloaded Android 10 GSI from https://developer.android.com/topic/generic-system-image/releases and AOSP 10 for XZ3 from https://developer.sony.com/file/download/software-binaries-for-aosp-android-10-0-kernel-4-14-tama/. I used the latest platform tools. I flashed oem_a, oem_b, system_a and system_b. After that, I did a wipe with fastboot -w command and finally reboot my device.
I checked that everything worked fine. Wifi and both sims worked fine.
After that I flashed the firmware H9493_Customized TW_52.1.A.3.92-R4C with newflasher and wiped it again. Did I do everything correctly?
Thanks.
If anyone wonders, no. It didn't work. I tried with custom roms and it was the same
I tried everything. I tried installing LineageOs, pixelsperience, Sony AOSP 10, 11, gsi 10, 11, and stock roms and nothing. Sims are detected some time, but stop after a while. i put an sd card instead of a sim card and it was not detected. I assume it is a hardware problem.
Well, thanks for helping
I'm having this exact same problem on my XZ3, thought I was going crazy but makes me think it's maybe not hardware related to find someone else with the problem...
