FOR DUAL SIM IMEI REDMI 9 LANCELOT - Redmi 9 / Poco M2 Guides, News, & Discussion

FOR DUAL SIM IMEI REDMI 9
REDMI 9 IMEI NULL/ERROR
1. PREPARE rom_eng/CSC according to each device, take the file preload&cust&md1img to be replaced or moved to a global rom
(use: when reading dimauimeta it's easier & can directly write imei , remember only imei
2, if you want everything you have to install the STROMBAKER FOR LANCELOT kernel)
2. Direct flash global rom version preferably below 11.8.O (remember to replace 3 files numbered 1), after flashing, open Mauimeta and click connect, just unplug and plug it in directly without having to turn it off, write only IMEI 2 (safe for initial boot and backup process), then disconnect & turn on the cellphone normally.
3. After the main menu appears, just check the IMEI has appeared in *#06# or in the settings, if you can unlock the bootloader, you can go to the next stage.
4. unlockbootloader, install twrp preferably version 3.5.2, then in twrp backup only nvdata & nvram& boot, then install strombreaker kernel or special interest in lancelot.
5. directly open Mauimeta click connect, in twrp just restart the system and finally Mauimeta reads automatically, then enter both IMEI and restart again, and check IMEI *#06#
6. if you want to keep using the kernel, you don't have to continue this step, but if you want the original kernel, we continue.
back to twrp, just restore the backup results and restart, check the imei, both are still complete and change only the kernel (return to the original kernel)
7. I tried to upgrade to a rom, the only remaining IMEI 2, if you want 2 IMEI to read, do the above steps again.
ATTENTION: do not update the rom for sure the imei will be lost.
my advice:
MAUIMETA ~ requires preload reading which I suggest replacing earlier & cdc (well, we install this cdc manually, download the file, when Mauimeta asks for our cdc in the computer manager and we install it manually on the reading in question in the computer manager).
LIBUSB~ is useful for locking the mtk preload when first plugged into the computer.
BYPASSMTK~ is useful for locking preloads but with preload changed from rom_eng, so bypass software is not needed when flashing.
so the important thing from these 3 points is the cdc file
very few people want to explain this wide in my opinion.
thanks for CAMMARA.

I tried it with Miui 12.5 with android 11 and it didn't worked. I mean, I already had the IMEI 2 written and working, but when I installed the stormbreaker kernel it was softbricked, and not detected by MauiMETA. So I didn't go any further. Is there any advice for this?

kernel use if you done flash rom global and can open menu normal
after that you instal kernel
if you instal kernel after flash, you phone will error to register activation

the essence of writing imei is only preload from rom_eng and md1img.img from rom_eng
the process
1. just flash preload and md1img
preload : to read boot without complicated bypass
md1img : for imei writing permission
after flash md1img we must format nvdata and nvram from flashtool so that no errors occur when entering Mauimeta (data format is in scatter)
2. For IMEI writing, use the Mauimeta application, IMEI writing is only for IMEI Sim2, if all are written, there will be an error.
3. If you want 2 IMEIs to be written, you have to complete the above process until the start menu opens, then go back to TWRP, install the Strombreaker kernel, then open Mauimeta again, just write down all IMEIs (kernel works fine on ROM 11.0.9 or above)
required files:
1.preload.bin from rom_eng
2.md1img.img from rom_eng
3.mauimeta good version 10
4.cdc driver for advanced reading of mauimeta
5. flashtool with DA and AUTH, can be used bypass
6.unlockbootloader for those who want to use the strombreker kernel via twrp,
7. the root process is easier in minimaladb
100% success guaranteed

The preload and md1mg will be copied from rom eng? And then move it to global rom(11.0.9)? And then flash it?

no,
flashing version 11.0.9.
after than flash just preload & md1img,
than you will bee write imei with mauimeta
remember only imei simcard 2 if you not instaling kernel
step
1.flasing v11.0.9
2.unlockboitloader & instal twrp
3.flash md1img & preload rom_eng
4.format nvdata & nvram, addres & partition in scatter rom folder image
5.open mauimeta write imei simcard2(if not use kernel),if 2 imei write after write imei you reboot to twrp and instaling kernel(best strombreaker)
enjoy

news trick
# for not unlock bootloader
1.preload.bin and md1img.img from rom_eng
2. flash format&download or flash download rom version 11.0.9 (insert or replace the preload file from rom_eng)
3. when finished, flash only md1img from rom_eng then format nvdata (the format code number is discatter)
4. after that open mauimeta(cdc drive is needed to read imei) write only imei simcard 2, reboot
5. Please enter micloud & register for the unlockbootloader process if needed.
# for already unlocked bootloader
6. root hp & go to twrp install strombreaker kernel, restart and enter mauimeta write both imei simcard 1 & 2
7. flash again using rom version 11.0.9 uncheck recovery, vbmeta (all vbmeta), userdata, super, boot, logo, md1img.

What is hp sir

You mean root my device? And then Im going to install twrp? If I successfully installed the twrp, Im going to reboot my device? And enter mauimeta? (In what state fastboot or just turn off the phone for entering mauimeta?)
Then if im successfully write both imei 1 and 2
Im going to flash the miui 11.0.9 and uncheck recovery, vbmeta, user data, super, boot, logo, md1mg?( in fastboot too?)
