first step, you flash global rom, unlocbootloader, install twrp, open mauimeta only imei 2, open twrp backup except super files.

the second step. you open mauimeta write imei 1 & 2, open twrp install the strombreaker kernel, turn on the normal phone.

third step, open twrp, restore backup files, restart.

check imei

may be useful.

How to backup NVDATA ?
[Redmi 9 / Poco M2 Guides, News, & Discussion] VD171:
Doing a readback with spflashtool or doing a backup with twrp.
[Redmi 9 / Poco M2 Guides, News, & Discussion] sddhruvo:
Kind of new to xiomi. I waited 1 week to unlock bootloader. After unlocking i tried to install twrp recovery. On fastboot boot recovery.img command my phone went to bootloop. It wont stop even when my battery depleted completely. Whenever i connect it with pc bootloop starts again without pressing anything. I was frustrated then with sp tool mistakenly formatted phone without any system backup. Eventually i flashed downgraded stock rom. But my bootloader somehow locked again. Don't know how! And now my imei gone. Can't follow previous bootloader unlock process, cause adding account in mi unlock status reauires active sim card inserted. So now i can't take backup after changing imei in eng rom. Just imei lost. Everything else works. Am I missing something here? Any suggestion?
[Redmi 9 / Poco M2 Guides, News, & Discussion] VD171:
You should never flash using the "format all" mode, or you will lose imei and mac.

If you flash the file misc.bin, you will got a bootloop.
[Redmi 9 / Poco M2 Guides, News, & Discussion] akbarshoxdedamirzayev:

Ok I need ur guys help ASAP

device redmi 9c angelica mtk chipset

problem: what ever I do, I cannot seem to install eng rom without bricking the device every time.

I tried miflash, flashtool..they go red and get stuck bricking the device.

I do cmd prompt and install The files one by one, all With succes and at the end when I do fastboot device: it goes off and brick.

what can be the problem? does the eng om don’t match? some People say downgrade to miui v11 because v12 doesn’t accept eng rom, that leaves me with not being able to find an miui v11 for redmi 9c. This is the only thing I didn’t try out because I could not find the v11 but the rest i tried all.

help pls

hiya, long story short without reading much about sp flash tool i used format all + download mode, im trying to restore my imei and everything i read led me to "go install engineering rom coz meta mode doesn't work in global rom", idk if that's still up-to-date but that's what im planning to do. I flashed this rom via fastboot while i was on miui 12.0.1.0 and got my device hard bricked, i restored it with sp flash tool to miui 12 and it works so i tried to sp flash your engineering rom but every time i try it says "STATUS_EXT_RAM_EXCEPTION", ive read your post about sp flash tool errors but "upgrade mode" doesn't work at all. Any recommendation what to do?

Also big thank you for making all guides and providing so much, love your dedication. Thank you again.

edit: also to avoid hassle with bootloader locked, im unable to readback with engineering rom scatter file, same error but if i load global rom scatter file it readbacks fine

edit2: can't fully flash global rom as it says that exaid and cust are "status_sec_image_too_large" and something about verified boot, i have no idea how to fix it.
[Redmi 9 / Poco M2 Guides, News, & Discussion] VD171:
I suggest you to flash the SAME miui version present on the device.

And then, you try to flash another miui version.
[Redmi 9 / Poco M2 Guides, News, & Discussion] yatsukiko:
Thank you for quick answer however seems like i edited my post too late, i can't fully flash same rom as "exaid" and "cust" are "status_sec_image_too_large" and it wants me to get a verified ones I can't really find an answer for that anywhere, do you happen to know answer for it?
[Redmi 9 / Poco M2 Guides, News, & Discussion] VD171:
Just try to skip them firstly.

If you can flash the firmware again, you may flash the full rom again too after.
[Redmi 9 / Poco M2 Guides, News, & Discussion] yatsukiko:
I have tried and unfortunately same issue, can you by any chance help me on telegram(@yatsukiko) instead as its faster? Thank you for your time.

[Redmi 9 / Poco M2 Guides, News, & Discussion] yatsukiko:
After flashing same rom as the one on device same issue with "STATUS_EXT_RAM_EXCEPTION" happens, both in download and upgrade mode

for the record, the only rom im successful with flashing is "lancelot_global_images_V12.0.1.0.RJCMIXM_20210609.0000.00_11.0_global_0b17afb77b" any chance that this engineering rom is not for my phone?

[Redmi 9 / Poco M2 Guides, News, & Discussion] yatsukiko:
Flashed global miui, readback md1, flashed eng md1 then readback it, they are exact same files, therefore i assume that md1 doesn't flash

edit: less related, stormbreaker kernel soft bricks my phone and i saw someone else had this issue, feels like there are two types of lancelot devices
[Redmi 9 / Poco M2 Guides, News, & Discussion] hckbkl:
1.flash romglobal v11.0.9 (insert preload.bin from rom_eng)with flashtool(use mtk bypass if not work), after flash all, flash again only md1img from rom_eng(that md1img can to write imei if you not have backup nvdata)

2.open mauimetawrite just simcard 2 imei, reboot.

3. unlockbootloader(login micloud and unlock)

4.after unlock install kernel strombreaker v1 from twrp

5.open mauimeta write imei simcard 1&2

this file boot.img if you not have kernel strombreaker

change boot.img in flashtool with this and flash(just boot.img flash)

i am indonesia very hard to speak english, i hope your understand
[Redmi 9 / Poco M2 Guides, News, & Discussion] yatsukiko:
Hi, thank you for your help but preloader from engineering rom is the issue, it doesn't want to flash it i get the status_ext_ram_exception, if i flash it with fastboot my phone only boots into the "EDL" mode

I also want to add that i have unlocked bootloader, i also made backup of seccfg in case i can't unlock it again.

edit: flashing your boot.img soft bricks my phone
[Redmi 9 / Poco M2 Guides, News, & Discussion] hckbkl:
if you want to wait I will share the file scatter,md1img,flashtool,boot.img(replacement for strombreaker kernel),mtkbypass,preload. use it wisely if you succeed and don't use the other party's imei

you can learn the program which I will share later to run it because it is too broad to explain it
[Redmi 9 / Poco M2 Guides, News, & Discussion] yatsukiko:
I also want to mention that maybe this is efuse related? it seems like i can't go to firmware lower than about 11.09, i can't really test it since my internet is quite bad.

also yes please, whenever that you think will help me, this phone is quite new, barely a year and if its bricked like that, quite a waste :/ thank you for your time tho

asalammualikum warohmatullahi wabarokathu

i am sorry just translate, i am indonesia

semua file ini sangat berguna.

matikan antivirus untuk mengekstrak ataupun menjalankan program ini.

langkah penting

1.flash dengan flashtool format&dowload v11.0.9.0 tanpa mengganti file.

2. setelah itu flash hanya preload dan md1img/md1rom file yang saya cantumkan

3. setelah selesai format nvdata dan nvram, adress dan partisi ada didalam scatter(maaf saya lupa copy scatter tetapi semuanya sama atau ambil scatter dari v11.0.4.0)

4. jalankan mauimeta tulis imei hanya simcard 2,reboot

5. login micloud, unlockbootloader, instal twrp dan vbmeta file saya, cara mudah menggunakan flashtool ganti file recovery.img dan vbmeta.img

6.hidupkan ponsel sampai ke menu awal setelah melewati registrasi

7.reboot dan flash boot.img file saya, setelah itu buka mauimeta dan tulis kedua imei, reboot

baca dengan teliti perintah yang saya berikan dan sebarkan tutorial ini ke saudara lainnya untuk saling membantu.

U should try without tools, do it with command prompt one by one, for example fastboot flash blabla.img blabla.img..and so on and so on.

for Some reason some tools just don’t pick up the eng rom or other roms.

I've tried fastboot already, i also want to mention that stormbreaker and "Shas Dream" kernels soft brick my phone, i don't know how to get boot logs so i can't provide much info.

Fastboot flashing showed no error so did sp flash tool, afaik md1img doesn't flash without preloader but engineering rom preloader bricks my phone so /shrug.

I haven't tried flashing engineering rom though twrp yet but i don't think it will help much xd.
[Redmi 9 / Poco M2 Guides, News, & Discussion] MrCarlo77:
Ok just without getting confused here, what’s the first thing you want to do?

[Redmi 9 / Poco M2 Guides, News, & Discussion] hckbkl:
if you read carefully my post, insyaALLAH, you will understand by using the strombreaker kernel.

but if you want easier, use md1img rom_eng and write only simcard imei 2 only.

if you want to go further, you have to believe carefully. insyaALLAH useful.
[Redmi 9 / Poco M2 Guides, News, & Discussion] MrCarlo77:
I know the problem, i had the same I was thinking at the end the roms were corrupted or something but it wasn’t. if you do it with tools you will brick it, I don’t know why but it’s just like that.

you should to it manually,go to your eng Rom folder and shift right click Open Powershell window here.

from there you go one by one,

fastboot flash recovery recovery.img

fastboot flash cust cust.img

fastboot flash vbmeta_system vbmeta_system.img

fastboot flash efuse efuse.img

you Do this until fastboot flash userdata userdata.img

now you should have installed the engineering rom, do this first then we go to meta tools.

Look at how your efuse is named in your eng rom folder, then Do : fastboot flash efuse (name of the efuse file)

but you said it doesn’t exist, what phone is it ur using?

does the efuse show up when u open the scatter file in sp tool? Post a screenshot of it just post don’t flash it with any tool

At least it’s flashing now so we r on the right track:)

Also it was always flashing, flashing was nevere really an issue except trying to flash preloader with sp flash tool, its much different than the og one

my device is xiaomi redmi 9, mt6769T which is same as mt6768, before flashing anything i saw my phone was "galahad" via drm-info or smth like that i don't remember now

Thanks hckbkl! Thanks to you I got my two sim slots working again. Instructions translated into english:​

turn off the antivirus to extract or run this program. important step

1.flash with flashtool format&download v11.0.9.0 without changing files.

2. after that flash only preload and md1img/md1rom files that I included

3. after finishing the nvdata and nvram format, the address and partition are in the scatter (sorry I forgot to copy the scatter but they are all the same or take the scatter from v11.0.4.0)

4. run mauimeta write imei only simcard 2, reboot

5. login micloud, unlockbootloader, install my twrp and vbmeta files, easy way to use flashtool replace recovery.img and vbmeta.img files

6. turn on the phone to the start menu after passing registration

7. reboot and flash my boot.img file, after that open mauimeta and write both imei, reboot

Read carefully the commands I gave and share this tutorial with other brothers and sisters to help each other.

I brick it after a downgrade to 12.5 and lost all my data (also IMEI).

Thanks your posts, I get restored it first with ENG ROM and than also flash MIUI 13, but without IMEI I can't use my SIM.

I tried to use MAUI META v10.18xxxx with ENG ROM but I reached 99% and than program stopped (I think timeout coming).

Where do I make mistake?

Maybe don't I flash the correct ENG ROM?

Maybe don't I press correct buttons on smartphone before connect with MAUI META?

Maybe I have to unlock bootloader, in this case how I can do it?

p.s: my fault, the first time I used SP_Flash_Tool I selected FORMAT ALL+ DOWNLOAD, do I generated a irreversible problem?
