If the issue is the baseband, sometimes get fixed flashing the latest firmware, anyway, I guess, actually you have a backup.
[Redmi Note 9 Guides, News, & Discussion] Markiexp:
we finally manage to flash miui 12 but both imei are unknown, after doing a restart it boot loop logo again.

we don't have any backup on the previous system, just the photos only.

will try to flash old stock to latest
[Redmi Note 9 Guides, News, & Discussion] SubwayChamp:
What I said is different. IMEI it´s different than baseband. Without a baseband working, i.e. a baseband null, you won´t be able to recover the IMEI/s. So you have to fix it first, in the way I mentioned. Maybe the ENG firmware, helps in your case.

good forums. I'm new to the forum and I have a problem. My research to solve this has brought me here. I couldn't find the exact answer and wanted to ask you guys. I have a redmi 9c (m2006c3mg) device and I took this device in a mode from test points with a request to flash it. But I don't know exactly this mod I bought. The phone appears as Mtk Com Port in my device manager, but I could not boot my device normally with any key combination, battery removal and removal. All I want is to boot my device normally thanks for your help
[Redmi Note 9 Guides, News, & Discussion] SubwayChamp:
Not sure why you ended up with such drastic test point method, only few MediaTek devices need it in the world.

Be sure to have the battery charged, and press the three buttons for about 8 seconds, to can boot, anyway, booting or not may depend on what led you to this state, you did say nothing about.

nevermind i flashed the stock rom again

but i have one question:

how do i change the build from user to userdebug build?

i need to mount the /system to rw but i am not able to do that.

any tips?

btw i messed with magiskhide props config and that softbricked my phone, and i had to flash my stock rom again. I changed the type.build to userdebug but after that i was stuck at the logo when booting.

also another question:

i downgraded MIUI to V12.0.3.0, what is the best TWRP build for that?
[Redmi Note 9 Guides, News, & Discussion] VD171:
You can't modify system, if you do this, your device will be bricked.

Modifying the build.prop is not an enought solution.

You can spoof that using XPRIVACYLUA:

Yes, I had one other usb cable I tried it but didn't work.

It is detected well while in other modes such as system recovery mode and normal modes

The device is undetected only in fastboot mode.
[Redmi Note 9 Guides, News, & Discussion] Flying_Scotsman:
Did you try having a Windows Device manager open while you are working. It is possible that Windows will find itself short of drivers as you change booting modes.

(Maybe the device even takes a new "identity" in fastbootd?)

(You will know that you are watching for ⚠️ appearing in Device Manager, then perform the Windows update while in that booting mode)

What should it be ??? Please help, sorry for my english
[Redmi Note 9 Guides, News, & Discussion] VD171:

Probably, you need to flash the whole MIUI again, except userdata.
[Redmi Note 9 Guides, News, & Discussion] revhappy:
Hi @VD171 , I need your help!

My device is Redmi Note 10X 4g(Merlin) with China ROM. It was MIUI 12.0.8.0 and then yesterday I recieved an update of lower version MIUI 12.0.5.0. It was so stupid of me everything was working fine with my phone, google play services, gmail, google maps everything. But after I installed the update, all google apps stopped working.

Mi Store shows google apps "instal" button as disabled and even if I try using apk to install google play services and google framework, I am not able to add a google account. When I got to Settings -> accounts -> Add account -> google, nothing happens. So I think with this update they have disabled google play services from working properly.

I tried to unlock my bootloader and did everything possible, but the Mi_Unlock.exe app doesnt detect my phone at all. When I click install drivers on the settings button, it tells me to connect my phone and detects my phone and installs drivers successfully. But the main unlock section, doesnt detect my phone.

So I am pretty much stuck. Any suggestions on what I can do? Can I get back somehow to 12.0.8.0 without unlocking the bootloader?

Would really appreciate your help!

Thanks.

Edit: I have an update! In my next post.
[Redmi Note 9 Guides, News, & Discussion] revhappy:
You guys are awesome! I am so glad I read you posts and this worked for me as well.

Now I got this message, not sure what it means by do not add account in MIUI again. I guess, the fact that it is added already to this device is fine?
[Redmi Note 9 Guides, News, & Discussion] mars08:
I have a M2003J15SC (China) Redmi 10X 4G and got the bootloader officially OEM unlocked last week.

Since then I have installed the latest official Xiaomi Gobal Rom, using MiFlash. The phone works fine, no problems.

Can I now safely lock the bootloader using the Fastboot command? I've seen several comments which advise against it, saying the phone will be bricked.

If the worst was to happen... and the phone IS bricked, is it something which can be fixed without taking it to a service centre or using EDL mode?
[Redmi Note 9 Guides, News, & Discussion] revhappy:
Awesome, can you tell, which version of Chinese rom were you on? Also which guide did you follow to flash the global rom?
[Redmi Note 9 Guides, News, & Discussion] VD171:
Good work, my friend.

After you apply to unlock your device, you need to wait the hours for unlocking the device.

After 162 hours you can try again and your device will be unlocked.
[Redmi Note 9 Guides, News, & Discussion] VD171:
After you flash the whole MIUI again, you can lock the bootloader.

If you got bootloop, you didn't flash the WHOLE miui.

You really need to flash the full MIUI, okay?

Good luck
[Redmi Note 9 Guides, News, & Discussion] mars08:
I got a bootloop on my first attempt, when I just ran the *. bat file in Fastboot mode. It worked properly when I used MiFlash. The phone is fine.

I have read that locking the bootloader on a Xiaomi China phone... after installing the Global MIUI... will result in a brick. Maybe that is old information.
[Redmi Note 9 Guides, News, & Discussion] VD171:
I'm not sure.

Just flash the china miui :)
[Redmi Note 9 Guides, News, & Discussion] mars08:
The phone was running the Chinese V12.0.4.0.QJOCNXM ROM.

My first attempt to flash it in fastboot mode (using the "flash_all.bat" file)... seemed to work. But the phone ended up in a bootloop.

On my second attempt, I used the Xiaomi software (MiFlash 2021.2.26.0) and it was a success. The phone is now running Global MIUI V12.0.8.0.QJOMIXM and working perfectly
[Redmi Note 9 Guides, News, & Discussion] revhappy:
Thanks! Can you please advice, can I flash the global ROM after I unlock my device? I am currently on China ROM 12.0.5.0 (RJOCNXM). I got an OTA update to downgrade from 12.0.8.0 (QJOMIXM) and that screwed up my google playservices.
[Redmi Note 9 Guides, News, & Discussion] VD171:
I'm not sure, my friend.

Just flash it using fastboot, if you got booloop, you can flash china rom using fastboot too.

PSA: Flashing MIUI Global on these Xiaomi devices may brick your device

If you flash MIUI Global ROM on certain Xiaomi devices with a locked bootloader, your device will not boot. Here are the Xiaomi devices that could brick.

www.xda-developers.com

I notice they say

Is there anything else I need to be concerned about?
[Redmi Note 9 Guides, News, & Discussion] VD171:
The EDL mode and authentication can be needed if you are flashing using spflashtool.

If you are flashing using fastboot, that doesn't matter.

If you flash using the file "flash_all_lock" it will relock the bootloader, please avoid that.

@VD171 @mars08 Thanks a lot for all your help! Today exactly one week after I applied for unlock, I was able to unlock my phone. Then I followed the steps mentioned by @mars08, used MiFlash tool and flashed the global ROM Global MIUI V12.0.8.0.QJOMIXM. I chose the "Clean all" option and not "Clean all and Lock". After about 1200s elapsed, I got flash failed message due to flash timeout error. But surprise, my phone automatically rebooted and it was already flashed properly to the global ROM. I noticed a strange message when the phone rebooted. It said, my phone is locked and asked me to enter MIUI account password. So, when you flash with the Mi Flash, I think it already adds the account and you are made to enter your Mi account pwd.

So I am very happy, my phone is back to normal now. Thanks again guys :)
[Redmi Note 9 Guides, News, & Discussion] mars08:
I'm so glad it worked out for you.

As I understand it, getting an error message during the flash process is not unusual.

I'm surprised that the bootloader is locked again. Have you confirmed it with the "fastboot getvar all" command?

Did you flash the Global ROM to a China model phone? I ask because locking bootloader on that model, after flashing with the Global ROM, is supposed to brick it! And that's why I've left mine unlocked...
[Redmi Note 9 Guides, News, & Discussion] revhappy:
Hi,

The bootloader is still unlocked. I am talking about this message:

I think it is a security feature.

Actually I got the same message in Chinese when I used the Mi Unlock tool and I didnt know what it was.

Even I got confused and thought that my boot loader is locked. Then I went to developer options and checked it is still unlocked.
[Redmi Note 9 Guides, News, & Discussion] mars08:
Ah, that message... the Mi account asking you to log on.

Is your phone hardware the Chinese model?
[Redmi Note 9 Guides, News, & Discussion] revhappy:
Yeah, this is actually Redmi 10X 4gb/128gb, launched in China almost a year ago . Let me know if you manage to lock your bootloader. I just installed most of my important apps, including banking apps and my work email and there were no problems, so I think unlocked bootloader should not be a restriction for now, although we dont know in the future.
[Redmi Note 9 Guides, News, & Discussion] VD171:
Once you connect to your miui account, it will be saved on your phone.

After formatting the data, the phone will require that miui account again, but only once.
[Redmi Note 9 Guides, News, & Discussion] revhappy:
I just realized the MIUI version which has Q in it is based on android 10 and the one that has R in it is based on andriod 11.

I had received an update in my China ROM to move from Q to R, the MIUI version number sounded like a downgrade 12.0.8.0 to 12.0.5.0, but they have a lower sub version number for android 11.

Anyways, I think they have made the change in this R version to disable Google play services working in China ROM. So, if you are on China ROM, do not update to the R version. Just stay on the Q version, if you want to continue on China ROM.
[Redmi Note 9 Guides, News, & Discussion] mars08:
Thanks for that.

The internal product name for Android 11 is "Android R”. Version 10 is "android Q"

I'll just wait until there's a Global version of the new ROM. No rush. In the meantime, I won't lock to bootloader because all of all the warnings. There shouldn't be any issues with installing apps. It seems that having a ROOTED device is what causes those problems.

Now, just enjoy your fresh phone!

I'm planning to flash SHRP recovery when I successfully unlock my bootloader (2 days left of 7 days) but I saw that you need to flash a patched vbmeta before flashing a custom recovery.

The problem is that the vbmeta which is available is for other firmware (mine's MIUI - V12.0.8.0.QJOINXM) so I was wondering do I really need to flash it and if yes then can I flash the one which is available (i.e V12.0.5.0.QJOMIXM) ?

I just received my Xiaomi Redmi Note 9, Model M2003J15SG. Out of the box specs are MIUI Global, 12.0.1.0 (QJOEUVF). It's been a while since I rooted my old Oneplus 3, so I'm reading and trying to refresh myself.

Should I do a system update to the latest version of MIUI before I start the whole process, or am I better off staying at 12.0.1.0?

Is there a way to get my current boot.img and vbmeta.img directly off of my phone to fall back on in case of problems, or should I get those from MI website instead?
[Redmi Note 9 Guides, News, & Discussion] VD171:

First, you need to unlock bootloader.

And then, you can flash patched boot.img and patched vbmeta.img.

I suggest you to flash the latest global release: Android 11 V12.0.1.0.RJOMIXM

Fail on step 1. I cannot unlock and start the wait period. The unlock tool does nothing when hitting the Unlock button. Could it be because my windows 10 PC is only 32-bit? (`fastboot devices` also shows nothing.)

SIM card is inserted. Logged into MI account on phone and unlock tool. Tried a factory reset. Tried an older unlock tool version. I'm in fastboot mode. Nothing.

My 64-bit computer is linux and I don't think they have an unlock tool for linux. On linux, `fastboot devices` finds a fastboot. But running the unlock tool in Wine doesn't work, because wine gecko is not rendering the html sign in page website.

Here's how I solved it:

Unzip, miflash_unlock-en-5.5.224.24.zip, Version 5.5.224.24 in folder 1

Run and signin in Unlock Tool, batch_unlock.exe (v5.5), phone was not found in fastboot, so then close.

Unzip miflash_unlock-en-3.5.910.35.zip, Version 3.5.910.35 in folder 2

In folder 2, run as administrator driver_install.exe

Reboot phone in fastboot mode, then connect

In Windows device manager, find Android listed under Other devices with a yellow warning icon

Right-click, Update driver, Browse my computer for drivers, Let me pick from a list..., Android phone, Xiaomi composite MDB interface, next and proceed to install driver, accept warning from microsoft, etc.

In folder 2, run miflash_unlock.exe (v3.5) and signin

Hit the gear icon, choose Check for Click the button to install the drive[rs]

Keep v3.5 open

In folder 1, run batch_unlock.exe (v5.5), you should still be signed in

Click refresh, Merlin phone is now found in fastboot

Finally click unlock and it finally works, timer counting down

I'm using also powerline, but eventhough I had same name with my router or with different names or even trying to connect to my WiFi, the phone won't connect... in other routers it can connect normally...

My device got bricked, it doesn't enter to fastboot nor recovery, I tried blindly to get it through ADB or fastboot commands but nothing, and it is not recognized through Sp Flash tool, it keeps for just 1 second bootlooping with blank screen, a short vibration, disconnects and reconnects in these two modes intermittently.

I just flashed the dtbo file from the ENG firmware from here https://androidfilehost.com/?fid=14943124697586340169 never mind what harmful can be a file supposed for this model.

I managed to shut it off by pressing the three buttons for some seconds, but it's the same with PC that doesn't recognize it.

From what I know, download mode works with device off (no need to press any button) and EDL works flashing the preloader, but I can't do that so no modes available.

Some ideas? Maybe discharging all the battery may help (although I can power it off) or opening back cover would be needed to test point it and this would be the last resource?
[Redmi Note 9 Guides, News, & Discussion] VD171:
You need to flash the full stock ROM again using spflashtool, my friend.

You can press "download" button to start flashing even with bootloop, I mean between while from a reboot to another.
[Redmi Note 9 Guides, News, & Discussion] SubwayChamp:
Thanks for reply. I tried that, you mean that in the short period device get detected, Sp Flash tool can retain it in the preloader mode to do the flashing.

I guess it needs an exact point of time maybe, I'll keep it trying it.
[Redmi Note 9 Guides, News, & Discussion] VD171:
It is instantly.

Just press "download" button, plug the usb cable and wait for next reboot of the device.

If spflashtool is not detecting the device, probably you need to bypass EDL auth first.
