boot.img incorrect -> lost Wifi features, how to get correct boot.img back?

Hello,
I had the intention to install CM13 on my newly purchased Mi5 (that came with "MIUI 7.3.4.0 Global stable"), so after unlocking, I tried to install TWRP on it at first. Because of the technical problems this currently still involves, looking for a solution, I stupidly flashed an incorrect boot.img on my device (originating from this thread that was about another MI5 ROM version). Now the device still works again after a factory reset, but without any Wifi features (Wifi connection, thethering).
Does anyone know how to fix this? I couldn't find any resource linking to another boot.img (I guess I'd need one for 7.3.4 Global) so far and I'm not familiar with Xiaomi phones enough to help myself otherwise.
thanks, r.

I have a big problem Help me please

Hi, I have mi5 32gb version, my rom version was 8.2.2.0 stable. I unlocked bootloader and installed twrp and install custom rom lineage os. But wifi was turn on but not connected any modems. I wrote password, connected and saved but not connected.
So, I returned 8.2.2 stable version with MiFlash but same problem.
Mac Adress is ok no problem.
What is problem?
Thanks your answer.

Did you install the firmware before the custom rom?
I think it might be the problem...
7.3.9 is the recommended one.. ask on the forum.

(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.
I'm Confused.....Pliz Help
Thanks In Advance.

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.

Very strange problem

Hi guys, I have a strange problem with my other Mi 8.
A week ago the screen suddenly turned off while device was still on, so I could connect it to pc and transfer files or listen sound from device. I flashed it through fastboot to stock rom but I didn't solve the problem. After 7 days, the screen turned on and it seems working fine. I think it's not a software problem cause I flashed it, but it can't be a hardware problem cause now it works...
It's a Mi 8 China version, unlocked by unofficial way with global ROM installed: should I unlock it officially? Could be this the problem?
What do you think about? Thank you.

Question [Help] Wifi unstable after flash

Hello all,
Trying my luck here.
I have a 11T Pro (Vili), International. I was using PE GSI and it was just perfect... fast, no issue, etc...
I wanted to do a small update on Magisk, and i've crashed the boot. Well, nothing bad, i'm used to that kind of thing, reinstall blablabla... and now Wifi is broken.
Wifi is working randomly :
- It takes ages to scan networks
- It connect, and disconnect after a few seconds
- Once connected bandwidth is not good
- Wifi button get disable without any reasons
And that : Randomly
Wifi is working for other devices
What i've done / tried
- Reinstalling multiple version of PE GSI
- Reinstalling MIUI Rom (with Miflash, and the firmwares) : for International and Europe, multiple versions...
- Flash modem.img
- Flash persist.img (in fastboot, not EDL)
Each time, the same : Wifi is not working correctly. I see the mac address in the OS. But Wifi keep connecting, disconnecting, etc...
Phone network is working perfectly (5G, etc...)
If anyone has any idea, i'm lost. I never had that kind of issue.
Thank you

Try to flash with Miflash, an A11, the best, the one that was on the phone when you bought it.

Android 11 version and mi flash fastboot rom?

Ho sorry, my brain wasn't working anymore, i hadn't tried going back so much regarding the version
Just flashed a Android 11 (Miui 12.5) and wifi seems to be back online and working.
I'm gonna update to latest MIUI and tried to reflash PE, and will confirm here
If it works : i own you a box of chocolate, a bottle of cognac, whatever is your poison !

Do you like to play with fire, GSI rom+Magisk+modules=?
There are AOSPs available.

Regarding the PE : i had it on my last phone. And when i switched to the 11T Pro, i've just checked the forums and people were saying to go with the GSI.
I've tried, and it was fine until now.
For info : I've updated through OTA from 12.5 to 13 (latest MIUI) : and wifi is back down !
God damn, that's crazy
Reverting to A11 !

For anyone getting to this thread : people on Xiaomi forums confirmed to me the Wifi issue with the last firmwares with some 11T.

Avoid stable Beta roms, latest Stable V13.0.7.0.SKDMIXM

It was with this one that i had issues.
I've tested V13.0.6.0 and V13.0.7.0 and both we're creating problems for me, and it was confirmed by users that are with MIUI. Both are labeled "Stable" but users report some problems with them
I unfortunately don't remember which firmwares was on my phone when i've got it
