Mi4i Imei & Baseband /Unknown - How To Fix ? - Xiaomi Mi 4i

Hi,
My phone bricked on update to 5.8.22, after repair rom no sim no baseband and no imei.
Baseband : MPSS.DPM.2.0-ec890b0
Please Help
Thanks

What do you mean repair ROM?
If you installed the same 5.8.22 again it might cause problems. I'd suggest you to try a stock ROM.
On developer ROM people face these issues. After installing stock rom you can flash developer ROM once again

I've done it and did not resolve, I tried all the available rooms and nothing

[Q] Samsung Vibrant problem, no IMEI, unknown Baseband and no service

Let's make this story short. I rooted my Vibrant, then I flashed custom ROM (ICS Passion) but after that there is no baseband, IMEI on system info about the phone.Also sim card isn't detectable(no service). My biggest mistake is that I didn't do efs backup.
So now, only solution is to flash to stock ROM (2.1) with ODIN?
I also have problem with my usb port so I'm wondering is there any way for flash to stock ROM without using ODIN?
THanks

Phone model number changed after flashing rom

Hi ,
I have a flashed a rom that I think did not work for my model ( Now my phone says model number is SM-G925K) and I have no more signal. I believe the model number is the issue, but I'm not sure...
It was supposed to be a SM-G920W8.
Any idea how I can reverse it back?
This is the rom that I tried to install : http://forum.xda-developers.com/galaxy-s6/development/rom-aterminatorg920f3zpa1m-6-0-11-0b-t3295183
This is the rom that I was on :

Please help!
flashed stock rom, re-rooted the phone and Flashed TWRP and the same old rom I had .. everything is fine now
Displaying different phone model is just a build.prop thing, no reason to panic.
The reason why the ROM you tried to flash doesn't work or give signal is obvious. The rom is posted in the 920F/I thread and therefore shouldnt really work for your device (920w8?), unless stated so (Xtrelite rom says it does). That beta rom has only 92xF bootloader/modem, which obviously doesnt work for you.

S7 g930f help neeeded cant detect sim card after flashing custom rom

hi, i got problem...i had stock oreo oficiall without any mods and i decied to flash some custom rom like s9 port teamexyking, now i cant detect any sim card on any custom rom....some help??? i flashed modem and bl and still nothing... looking for solutions, mb some1 can help..ty
I had the same issue and I think it was the same ROM, but it only happened after a day.
Re-flashing the ROM via a dirty flash didn't make a difference.
In the end I just changed ROM because I didn't want to spend too much time on it which worked, so it hasn't done any permanent damage.

Have u checked your imei number or baseband version ???
If baseband version is unknown or imei is null so u can't get netwrok
Or u have damaged your efc partition???
If u have none of this above problem
Than u should check your sim tray or go back to official stock firmware because I'm also on tha same rom by teamexykings and it's working superb
@up indeed my friend, i flashed official latest oreo xeo and its works... Ty for ur help guys

do you think if you downgrade android 11 to android 10 will the imei come back?
unfortunately it wont allow me to flash any older firmware only the latest one
You should try with this method https://forum.xda-developers.com/t/...oader-usb-vcom-and-cycling-rebooting.4322581/ the general procedure might suit for all MediaTek variants, I didn't check completely the thread, you should interchange some files for/from your model.
Probably, it requires at least the OEM unlock toggle to be switched.
Be warned that I didnĀ“t try it on a Samsung Mediatek device because I had the Exynos/Qualcomm A10/20/30/50/70 variants, not the MediaTek, but with most of MediaTek Realme, Xiaomi, it works.
You can add also this tool to the job https://github.com/bkerler/mtkclient.
Definitely some firmwares erase the baseband becoming to null, in the theory that IMEI is not really lost, then returning to a working baseband they also have to come back, but if they have gone then returning the baseband only, it only will return the ability to make calls.
