Redmi 2(8gb Indian version) VoLTE Support needed

Hello, I posted a previous thread saying theres no volte for redmi2.
The thing is i've tried almost every solution thats out there for enabling VoLTE. But still none of them works.
I've tried flashing Redmi2 Prime ROM(doesnt work) and even flashing other custom roms over it(still doesnt work).
I've tried flashing Volte Patches, Xiaomi Volte modems etc.
Ive tried installing Lineage OS firmware....and the ROM(ofcourse) yet to no avail
I got a suggestion to manually wipe all partitions...but i researched a bit and got to know it hardbricks your device(so thats gotta wait for a while)
So is my Phone a special snowflake among other Redmi2 or is it a problem in my SIM card? If so how do i know which one is at fault?
I know this post might not belong here...but i need a discussion on this one..because there might be other Redmi2 users out there facing the same problem....So if anyone has the same problem do say so in the replies...and we'll see together, which of the solution works by testing them

1)download Mi flash tool
http://en.miui.com/forum.php?mod=att...E5MTF8MzM2MTg0
2)
download fastboot rom redmi 2 prime global stable or china
http://bigota.d.miui.com/V8.1.3.0.LH...23ac47dab8.tgz
above is global stable link.
3) put your phone in fastboot mode, unzip the downloaded rom. (avoid spaces in between folder path/name eg "C:\New Folder\Extracted rom\...." is not allowed instead it should be like C:\New_Folder\Extracted_rom\.......)
4) open mi flashing tool see if your device is listed. refresh to see. select clean all (flash_all.bat) option from bottom of mi flashing tool.
5) click on flash, and let it boot.
you would be able to use VoLTE now in miui rom. if you want to change to any N based roms just flash twrp and clean install any rom.

I don't have any problems with redmi 2 prime rom. VoLte working flawlessly.

MI5 No service / emergency calls only after MIUI 8 update from Android 6-unlockedBL

hi, my xiaomi mi5 32gb/3gb ram had android 6(no ideea about version) and unlocked bootloader, bought from china with european version of the rom, gapps installed.
everything worked perfectly, no drops in signal, nothing to complain.
i updated to MIUI 8 Android 7 official and after that the signal dissapeared, the only moment i had signal was when i put a new simcard in the phone, and only for 2 minutes.
Then i flashed with XiaoMiFlash : gemini_global_images_V8.2.2.0.NAAMIEB_20170407.0000.00_7.0_global_95e92d22eb
-- the problem stays: no service/emergency calls only.
i have good 3G 3-4bars/4G sometimes, when it comes to signal in this location.
nothing helped.
flashing xiaomi-miui-hellas-7.0_gemini_V8_XTRV_7.4.20 with TWRP Recovery also didn't help my problem
Now i am with a phone with no signal, could you please give me some help to solve this?
i've seen a lot of people in this situation on forums, so a solution would be very good.
Perhaps the settings from the *#*#4636#*#* Hidden MENU, this way i would do it the way it is on a working phone.
Thanks, greetings. Dan

[HELP] Volte gone after flashing oreo custom rom

Today I tried several Oreo based custom roms on my g5s plus xt1804 sanders but while flashing back to stock I got '0' IMEI there so I tried resolving and got that working but now VoLTE is not coming and I am not able to call or msg anyone through my Jio 4G SIM.
I tried several methods of getting VoLTE back , posted in different sections here but none of them worked. Now please help me to get VoLTE back coz it's too urgent and I can't call anybody. Thank You

Cant Turned on WIFI/BT, Already Flashed for BT still not working

Hi , its been a year since i bought xiaomi mi 9-global rom(128GB) and all work properly.
if im not mistaken the first rom when i bought is MIUI 10 , then the last time i update if im not mistaken is around september in MIUI 12.02 for the latest security patch.
Suddenly problem occurs recently maybe around a week. where my Wifi & Bluetooth disconnected by the system and cant be turned on but it fixed it self as i restart and now its never fixed.
I already some of fixed below :
- Restart devices
- Wipe all data
- Factory reset
- Try to flash the ROM from official one MIUI 12.02
- Following some tutorials that reset bluetooth and wifi settings
- Try downgrading MIUI version to 11
but still didnt work the Wifi & Bluetooth setting always crash & cant be turned on , try CIE or CIU test found out that the proximity sensor also didn't work.
I also tried some tutorials that do in EDL mode to install persist mode but its not working due to the Authentication it says" i dont have the permission"
Is there anyway i can fixed the Bluetooth & Wifi in this device?? The Mobile Data is still working and other features still working except Proximity Sensor, WIFI, Bluetooth.
Is the only way is to let the xiaomi store fixed it?? this is my only phone so i need it alot and the office store probably going to take long since pandemic.
Please help me Xiaomi Pro's out there :crying:
Edit :
- my xiaomi account already match with the phone the proof is i can unlocked OEM using the xiaomi. But it seems i still dont have permissions to flash EDL.

I think it's safe as miui could be.
But be shure to follow step by step and take right rom version. If it's working you can flash original miui or custom roms.

Thanks for the suggestion, after i tried to flash to EU ROM i got new MIUI version which 12.04 , in global its 12.02. However the problem still happening or still remain unsolved. The bluetooth & wifi still cant be turned on, i tried on CIT it also not working and everytime the i try to open wifi & bluetooth settings , the settings always freeze and crash probably because it error. Is there any other solution you can provide?
Thanks

I think, if you have done a really clean flash with formating data, that it's a hardware problem.

yes, i did i already follow the instructions & having no error at all for the ROM and other stuff except the WiFi & Bluetooth.
But for me its just really weird, my phone looks still great from outside no bend, dent, or crack it never fall as well.
The problem starts occurring by itself like the system is forcing the Bluetooth & WiFi to off then at some point the WiFi is connected but not transferring any data after restart everything fixed then its not working at all, which when i tried to turn it on it will freeze or the system not responding or off by itself.
btw appreciate your answer, i'm still waiting for other solution if possible :crying:

Are you shure that you've got a global version. I had nearly the same probs as I've flashed the global on my eu hardware.

In my personal opinion there're 2 possibilities
Damaged hardware
Or
Modem Partition wrong or damaged
MODEM or RADIO - the phone's radio
Also called baseband, it is responsible for signals and on older devices may control wifi, bluetooth, and GPS (on most newer devices, these are handled by the kernel and ROM). Upgrades are country dependent and may improve or diminish battery performance, network signal strength, and roaming capability. It is also sometimes required to have a minimum Baseband version to use a ROM so that the RIL will play nice with the Baseband.
Modem firmware is a mini-OS for the cellular radio chip which has its own processor. Firmware is a general term, firmware exists for a lot of things on phone. The wireless chip for WiFi, GPS, and Bluetooth often has a firmware as can the GPU core among other things. These firmware files are usually located inside the SYSTEM or VENDOR partition. The modem firmware is special because it has its own separate Baseband Processor (BP) so the firmware is left out of the system image in its own partition.
Modem is not an Android-specific partition. It is tied to the hardware of the phone, but the kernel has a code allowing Android to interact with the hardware. But the baseband processor (BP) - which runs modem and is responsible for all communication through mobile networks e.g. call, SMS and internet - is totally isolated from Application Processor (the one we call CPU) and is not governed by Android kernel; it runs an independent RTOS.
May it helps you for getting a solution....

Thanks for the long and detailed explanation . My mobile network & GPS still work properly without any issues.
but idk if the Bluetooth & WiFi chip maybe fried inside
Maybe i just dont have any other option except to fix in mi store.
Once again thanks for the help :fingers-crossed:.

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
