Flashing Guide >> MIFLASH[GUIDE]⚙ USE XIAOMI FLASH TOOL by @NOSS8

A big thanks to use @axf for testing the firmware. He successfully installed a Global ROM on a Chinese Device.

SUCCESS!

Thankyou @RinaZet @NOSS8 for covering the discussion about the bootloader unlock in the thread.

For context please visit this thread below. Please note that the thread below is for Mediatek Device and I have converted more than 27 Redmi Note 12 Pro Chinese device to Global without bootloader unlock.

Redmi Note 12 Pro China to Global Without Bootloader Unlock - Hyper OS coming soon......

CLICK HERE TO MESSAGE ME I would kindly request not to ask me to do the same with other Xiaomi devices as the firmware to convert them is not yet available and I have not yet figured out how the firmware was modified to allow this. If you have...

1. This is completely stock rom which can be flashed on Chinese Redmi Note 12 Turbo.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
So, you found the trick for the Qualcomm socs.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
Yes finally. More Qualcomm devices are likely to be supported.

Need someone to test like I did with Redmi Note 12 Pro (Ruby).
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
You will become a hero.;)
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
Thankyou. I'm not the one who discovered it but it comes from China.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
Maybe but you are the first on XDA.

Does this require a connection to Xiaomi servers?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
Yes because developers on XDA never though about this or maybe never released it.

For Mediatek devices the firmware have modified cust.img file.

I heard everyone saying that it is not possible to do but after I did it with the Redmi note 12 pro, I had my eyes on Qualcomm devices. :cowboy:
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
Yes if a person has locked bootloader then it will need authorised flash.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
you don't think Xiaomi could cut off access to servers for unofficial sites?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
They can possibly do but since I know it since the Nokia days no matter what manufacturers do they will always leave a loophole which is then exploited.

Xiaomi is no different. There are lot of websites that already have the firmware stored on their own server instead of directly downloading from Xiaomi server. One such example is mifirm.net

Moreover you can also do a readback from the working phone and flash it back to a bricked phone to make it work.

My firm belief is that manufacturers shall not restrict general public from repairing and tinkering with the device software as it will hinder the development of custom roms which is slightly affected.

Also many after market repair shops and companies are dependent upon this third party websites to download the firmware.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
This would explain the 2 cases that we saw for the Xiaomi 13 Ultra and seen recently for a Mi 11 Ultra.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
Yes this is totally sad and discouraging.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
A question arises for the Redmi Note 12 turbo locked with a global ROM, will it be possible to unlock it without going through the EDL?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
Do you mean Bootloader unlock?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
With a Redmi Note 12 Turbo and with your method, the bootloader is locked with a Global ROM, but afterward what if we want to unlock it?

Btw:no Poco f5 Cn."1. This is completely stock rom which can be flashed on Chinese Xiaomi Poco F5 / Redmi Note 12 Turbo without unlocking the bootloader."
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
Then it will need authorised flash to Chinese rom and then unlock bootloader.

This rom is specifically for those people who want to have complete stock experience on a Chinese hardware those who don't want to unlock bootloader and use all the phone features alongwith payment apps.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] RinaZet:
I recently bought RN12Turbo from Chinese reseller. It came with locked bootloader and strange ROM. It had an unknown "global" MIUI version (14.0.6.0 TMRMIXN, instead of XM) with no OTA updates. Fortunately, unlocking bootloader was no different from global MIUI phones. But it left me wondering, how is that even possible to flash global ROM (let alone modified) to Chinese model and leave the bootloader locked. As far as I concerned it should lead to guaranteed hardbrick.

Now I see this thread and you promise the normal global ROM with working OTA. This is indeed very interesting. I can't be volunteer as I'm rocking EvoX now and honestly can't live without root, but I'll be watching this

BTW there's no Chinese Poco F5, it's either Chinese Redmi Note 12 Turbo or Global Poco F5
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
"But it left me wondering, how is that even possible to flash global firmware (let alone modified) to Chinese model and left the bootloader unlocked."

If you leave the bootloader unlocked you can flash a global ROM without risk of bricking.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] RinaZet:
I understand, it was a typo:) Fixed
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
Test the OP's method.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
Which needs to be renamed to cust.img but perhaps you have reuploded the zip since it was put online..
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
I can reupload it by renaming cust.img but I'm confused cause no other user faced the problem while flashing.

But the rawprogram is associated with the EDL flash and has nothing to do with fastboot flashing.

Also flash_all.bat also points to cust.img

fastboot %* flash cust %~dp0images/cust.img || @ECHO "Flash cust error" && exit 1
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
Yep, it's weird and the original zip on your PC is without the "img" extension?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
Yes that's the one I uploaded and the original one without .img extension. I have renamed it and started compressing it back and will reupload.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
Hello,

Thank you for posting the results. Can you let me know what problem did you face while flashing the phone with this ROM?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] uncle kin:
I'm from HK and trying get the phone via Taobao, seller said that come with miui 14, did I need to update to hyperOS first?

Or just flashing the rom with flash_all.bat
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
You can simply flash it using this firmware uploaded here.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] WiLs0407:
I shorten the file name of folder and than re-run miflash with all clear option
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
The rom has been reuploaded with the necessary extension for the cust img and with this rom you must use "flash_all_lock".
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] kotty:
does this global rom got network drop issue?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] shybanee:
Does it accept call recording ?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
Global stock rom do not have the Miui dialer but Google dialer.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] kalux3882:
@mvikrant97 can you build a rom in TW region for f5 ? because it use miui dialer.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
@kalux3882

If you have a Poco F5, unlock the bootloader, flash a TW fastboot rom while locking the bootloader.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
I can try it but will you test it?

Send me the rom link and I'll try to make one.

By TW you mean Tawain?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] kalux3882:
Oh it's a cn version but I still call it f5 sr
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
Ok, but on the case of your phone it says Redmi and not Poco.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] kalux3882:
https://bigota.d.miui.com/OS1.0.2.0.UMRTWXM/marble_tw_global_images_OS1.0.2.0.UMRTWXM_20240301.0000.00_14.0_tw_facead63c6.tgz

Yes that's it Taiwan rom, i'll test it in few mores day because my mi account can't unlock bootloader in this month 😅
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
@kalux3882

What is the point of flashing this ROM which is for the locked bootloader if you unlock the bootloader?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] kalux3882:
So i can flash this rom without unlock like mtk devices, read previous comments I think it must be unlocked fist
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
Look at the thread title.

With this ROM no OTA and no longer possible to unlock the bootloader without going through the OP.

Try a Xiaomi EU rom (bootloader must be unlocked).
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] uncle kin:
Just received, now bind and wait to unlock BL, will report you when successful.:)
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] kotty:
if I want to unlock boot loader again to flash custom ROM after flashing this..what i need to do is flash back stock china firmware to unlock bl correct?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
Why flash this ROM, since you can unlock the bootloader?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] kotty:
to try out stock global ROM first..if later on feel like flash custom ROM at least i know how to do it.so just want to confirm it can flash back ...
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
If you flash this ROM with the bootloader locked you will have to go through the OP.

The only advantage of the Global is that it is multi language, that's all.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] kotty:
sorry with is OP mean?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
The first post or the one who created the thread.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] uncle kin:
like the normal unlocking procedure. Bind mi acc and wait to unlock.

One more, you can pass the safetynet with hardware backed.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
Nope,CN device with Global rom.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] uncle kin:
You mean will like the cn unlock policy? LV5 community and real name register?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
Not sure I understand, if you are talking about unlocking Cn devices with HyperOS, it is a government decision.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] uncle kin:
Ok, I'll try next week.🤣
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
I answer, nope, just a flash with Miui/**HyperOS, then unlocking using the classic method or the **bypass method.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] uncle kin:
Using miflash 2022.5.7.0 flash_all.bat and the result with error failed to check space crc. Writing 'cust'

It's seem the cust using mondrian one?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
Rename the cust to cust.img(images folder)(no need, there is a cust.img), if the bootloader is unlocked, this rom does not work and if it is locked use "Flash All and lock.".
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] uncle kin:
I downloaded both file from google drive and seem that the cust and cust.img crc of mondrian and marble are same

"65EA98A2"

USE FLASH_ALL.BAT ARE GETTING ERROR IF USE FLASH_ALL AND LOCK I AM AFRAID THAT THE DRIVICE WILL BRICK.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
Some clarifications are necessary:

What device and bootloader status?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] uncle kin:
Already unlocked
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
Once again which device?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] uncle kin:
Redmi note 12 turbo / marble
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
This thread is for devices with bootloader locked.

For your case, either you flash a Global fastboot rom with Miflash without locking the bootloader or a Xiaomi Eu rom (recommended) and possibly an AOSP rom.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] uncle kin:
YOU ARE SO FUNNY :)
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
That's to say?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] uncle kin:
IN POST #8, SAID THAT NEED A authorised flash TO UNLOCKED, THEN YOU SAID HERE ONLY FOR DISCUSS ABOUT LOCKED BOOTLOADER.

I'm afraid that mvikrant97 was put a wrong file to marble BTW.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
The file is correct.

Try to flash the cust.img manually using fastboot command

fastboot flash cust cust.img
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
This is no longer the case today since it no longer provides this service and this thread does not concern you since your bootloader is unlocked.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
No need, its bootloader is unlocked.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] uncle kin:
Successful by removing "fastboot %* flash sparssecrclist %~dp0images\sparsecrclist.txt || @ECHO "Flash sparssecrclist error" && exit /B 1"

Will try flash and lock.bat later.:)
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] kotty:
so is still not working?will still stuck at Cust.img..hmm..just curious how many people success to flash this...why some can and some can't..
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] uncle kin:
I'm removed the script and flash successful, use flash_all to confirm the devices bootable then lock.

Or flash it use fastboot flash cust cust.img as mvikarant97 said.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] esipoko:
I had problems with Note 12 Turbo 16GB/1TB chinese variation on global ROM in network access. It continuously would disconnect from network speicially in 4G/5G mode. I found other people having same problem.

The problem doesn't exist in custom rom based on chinese hyper os or MIUI.

Has anybody experience the same, on locked global rom?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] RinaZet:
I experienced it on locked global ROM. Not from this thread though, my phone came with locked modified global ROM from seller.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
Replace the modem.img of the global rom with that of a CN rom and reflash the rom.

Not sure that this will be enough, the modemfirmware.img is necessary but it is in the firmware.zip.

With the bootloader locked this is not possible, you have to recompile the rom with the CN imgs.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] oncelxelil:
hello sir. I saw your post while browsing the forum. I have a Chinese version Redmi Note 13 Pro Plus 5G device. Fake global ROM is installed on the device. Can I switch to legal ROM without unlocking the bootloader with the program you shared? My device's bootloader is unlocked. I would be grateful if you help me.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
This post is not for your device codenamed Zircon however I have replied you back to your private message. Please check it and share any doubts you may have in private message.

I kindly request you to not post questions about your device here which will help to keep this thread clean. Thank you.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] esipoko:
I didn't find modem image files and don't know how to compile either. This ROM on Note 12 turbo 16GB/1TB is not stale in network connectivity.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
The modem.img is not sufficient, you need the modemfirmware.img but you will not be able to flash it since the bootloader is locked.

I contacted the OP about this.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
@esipoko

Maybe you want to stay on a stock ROM but as your bootloader is unlockable, you could try a Xiaomi Eu ROM.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] Baleck:
Hello, is there a way to make it works on Xiaomi turbo 3 ? Worth 260€ while Poco F6 (same but global) worth 500€
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
Not supported yet.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] MGREX:
Do you think this will work for the Redmi Turbo 3 too? now that the new poco is out

Where can you find it for 260? havent seen it for less than 300
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] Baleck:
I bought it in Shanghai
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] FirTelm:
hi, is there a similar method to Redmi Note 13 Pro 5G (garnet) chinese version to install global rom on it???
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
Yes there is but I have not tested it.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] feiplane:
sorry to ask here again regarding this method, i seems confused after reading whole threads

i have chinese redmi note 12 turbo, 12 + 256, bootloader is still locked with hyperos v1.0.3.0 UMRCNXM

how should i begin with the flashing? and does this method erase all user data like a ordinary bootloader unlocking process do?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
First unlock the bootloader.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] feiplane:
huh? isn't this method is for locked bootloader?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
I know, the OP had to change the title.

It's more of a test to prove that it's possible.

No update and re-unlocking the bootloader will be chargeable.

Best time to use a Xiaomi Eu rom.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] feiplane:
even more confusing...

actually i'm ok with cn rom but just 1 thing, android auto is not working since it needs to be integrated with the system for it to work that cn rom doesn't included...

this method does give some light to ppl like me that dont want to unlock the bootloader, which leads to all data has to be erased......

so what should i expect now? this method legit or not legit?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
OP changed the title now.

Thank you @NOSS8

For the unverse this ROM is for those people who want to use Global Stock ROM on a Chinese Device.

So what's new in this ROM?

On this ROM you can lock the bootloader back after flashing this Global ROM on a Chinese phone.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
In all cases the bootloader must be unlocked, Stock or Xiaomi Eu rom.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] feiplane:
so flash this with bootloader locked is a no go?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] NOSS8:
Nope.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
Without unlocking bootloader it will need authorised flashing.

So you better unlock bootloader and flash it.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] feiplane:
alright, thx anyway
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] RinaZet:
I already unlocked the bootloader, actually earlier today.

Here's some screenshots taken back when it was locked:

Spoiler content hidden.

Didn't take the screenshot of Device HW info... It was funny: the device was listed as POCO Redmi Note 12 Turbo :D
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
@RinaZet

Thankyou for the information on the bootloader unlock.

You thought it wasn't possible to Flash Global ROM on a Chinese hardware with locked Bootloader that's not your fault because that's just a myth now.:)
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] ekafjr:
But rn12t has a different band, even if it works, the signal will not appear
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
Everything works as expected.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] RinaZet:
There are 2 separated issues:

1. Absense of some 4G bands. It applies to almost all Chinese devices, the outcome is region-dependent but overall not so critical. One should consider it before buying.

2. Network (not just 4G, all network) connectivity lost that happens when RN12Turbo is running global MIUI (not sure about HyperOS) ROMs. It works great on CN firmware and on non-MIUI custom ROMs. I'd consider it critical as people won't be able to call you and you won't be able to call anyone during these connectivity lost periods, it may require reboot to fix... There are some fixed MIUI ROMs but they aren 't official obviously so you can't lock bootloader.

As for me, I experienced this issue maybe 1 or 2 times during the week I was waiting for unlock. But I use 1 SIM, I read that with 2 SIMs it happens more often. And then again, I had only one week to test

Some information about fixes:

Flashing this now. Note that the space in the tar path causes issues at first, but working around it by removing.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] axf:
Okay a couple of issues: (1) "cust" should be named "cust.img" for the flash_all script to work. (2) flashing "cust" gets "Invalid sparse file format at header magic" but continues.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] axf:
Well... I was not able to get this to boot (without relocking bootloader), but I will say that I had trouble getting the latest stock global rom to boot in any case, so maybe this is not a good data point for you.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
In that case it will be required to flash in EDL mode.

Are you willing to volunteer to flash the device in EDL mode?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] axf:
I can do this if you can point to instructions. However apart from this I am going to try to get the latest stock Poco F5 rom to work on this device first.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
Okay.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] TEK023:
wow what a big progression ! keep it up

I wonder if the network signal drop are fix ?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
We can try it on your phone if it is chinese.;)
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] axf:
Got the stock marble_global_images_OS1.0.2.0.UMRMIXM_14.0 to flash correctly (needed to use Xiaomi's version of fastboot instead of Google's). Flashing your rom (with cust renamed to cust.img) now.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] axf:
Flashed and booted your ROM without bootloader lock. Now for the moment of truth...
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] axf:
ROM boots properly after `fastboot oem lock`! Congratulations @mvikrant97!
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
Thankyou so much for the confirmation.

Let me know if IMEI, WiFi, Bluetooth, Camera and all other hardware feature works.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] axf:
IMEI, Wifi, Bluetooth, Camera all work properly. However, I am still stuck with the Redmi Note 12 Turbo (China) cellular band limitations. Let me know if you have any ideas regarding bands -- would be happy to try.
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
Without actually having the phone in my hands it is not possible for me to test.

I got no idea on how to fix that up.

How the band limitations are? Like frequent call drops or something or is the network coverage?
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] axf:
No problem, thank you so much for your work on this and congratulations again!
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
Thankyou for testing it.

I will be adding support for more devices now. Next device is in the lineup is POCO F5 Pro (Mondrian).
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] mvikrant97:
Can you please post some pictures like homescreen and about settings...
[Xiaomi Poco F5 / Redmi Note 12 Turbo (China)] axf:
Note that the cellular issue resolves if I am go outside (poor signal indoors).
