[ENGINEERING][ROM][OFFICIAL] OFFICIAL Engineering Firmware for LANCELOT (Redmi 9 / Redmi 9 Prime)
- Thread starter VD171
- Start date
ALHAMDULILLAH MAGRIB 24/06/2021 I got a solution and my cellphone works normally again without having an additional kernel in it. trial with backup files from twrp & backups from mauimeta "updateparameter" from redmi 9 has a brother.
the process:
1. just write imei 2 then backup ditwrp all except super files
2. I use kernel to write imei 1&2 then
3. after the imei is written and I reboot the cellphone into twrp and restore the backup results as a whole
4. when finished, open Mauimeta immediately, unplug it and immediately plug in the usb so it's easy to read Mauimeta, run the process until it opens read IMEI (if only IMEI 2 is listed click write without filling IMEI 1)
5. Open in Mauimeta update parameters, click the normal redmi cellphone backup file option, then click download to flash.
6. reboot see the results, the original kernel from xiaomi and can update software normally.
1000% success Thank God this is finished for the IMEI stage Later, I will search for the system

no boss. 1. backup only says imei 2 (kernel is still original)
2. write imei 1 and 2 followed by install kernel strombreaker v1.0
3. restore backup
2. write imei 1 and 2 followed by install kernel strombreaker v1.0
3. restore backup
I would like to use that rom as daily. How can I extend system partition to make it bigger? I do not have option in twrp to wipe system partition and then resize it.
I've tried like you said, imei 1 cannot be written still, kernel bugs and won't allow me to run miui12 normally (had to reinstall all again).
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.

Doing a readback with spflashtool or doing a backup with twrp.
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?

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.
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

You need MODEM META for that.Thank you man, please someone can post a tutorial how to fix the IMEI with this rom? Normal AT commands is not working
gives ERROR
2
Yes.
You can repair only imei for slot2 by yourself.
Only Xiaomi Centre can recover imei for slot1.
If you try to write the imei for slot1, you will get NV DATA corrupted and your device will be bricked in a bootloop.
If you want to recover the imei for slot2, just follow this step:
1. Flash the ENGINEERING ROM.
2. Enter in META MODE using MODEM META:
Download: https://androidmtk.com/download-modemmeta-tool
Guide: https://androidmtk.com/use-modem-meta-tool
3. Write IMEI for slot2 and keep blank/null for slot1.
4. Backup NVDATA partition.
5. Flash any other MIUI (or custom) ROM you want.
6. Restore NVDATA partition.
Done.
