After flashing with SP flash tools i lost my SIM connection and the camera app on the CAT B15.
I testet, IMEI was wrong, with MAUI is correct again. Flashed my old backup from MTK Droid and got the same. Camera app not appears and SIM not working.
The phone recognizes one or two SIM are inside, but SIM app stays grey and no service and no question about pin of the SIM.
Now i have a friends CAT, rooted and did a backup by MTK droid. Converted the backup to be flashable for SP flash tools.
Flashed again, and..... same again! No camera and SIM problem.
Is not really all new flashed??
What i'm doing wrong?
Thank you for help,

Hi, I´ve just got a Oukitel U7. This is a MTK 6582.
And at first look seems "nice". My issues start when I insert a sim card. Then it loses the Imei and dont connect to sim card. When I remove de sim card, I have Imei again.
So, any one experienced something like this ?
I already rooted, make a Imei backup, restore it. Flashed with SPFT and nothing seems to work.
Some ideias would be nice...
thank you

try to flash with new update with spft on needrom.com
I have poc f1 6gb 64gb varient. After a reboot it goes into a bootloop and the stock recovery appears saying NV data is corrupted wrriten in red. My device is unlock and it is running miui12.
I flash twrp and install nitrogen os, by which the device boots up but with no wifi and no imei. I search a lot on the web and don't find any solution.
To all the geart devs out there please help me.
Good day
There's a similar thread open that I dont want to hijack. I would appreciate suggestions to get the network side of the device working again. After some reading I think I messed up NVdata by using format all on spflash.
I have the:
Redmi 10 2022 (I believe it is selenes)
Model 22011119UY
Original firmware was 12.5.2.0 RKUZAVC (Note this is the South African market (ZA) with carrier locked to Vodacom.
Unlocked bootloader, stock recovery, able to access fastboot.
I flashed vbmeta, boot and recovery images to install custom firmware. Originally the device was bootlooping with no access to fastboot or recovery. I bypassed the secureboot and managed to flash selene V12.5.20.0.RKUMIXM (global) with SPFlash, after which I changed the blank IMEI numbers back to those on my box. I can now access fastboot and recovery. The device states (NV data corrupt) at the recovery page and wont boot into system.
After this I installed the China ROM for the selenes (V12.5.2.0.RKUCNXM). The phone boots into system fine, but doesnt detect any simcards or the IMEI numbers. ENG rom sees the IMEI numbers but has no signal.
Is the issue perhaps that you need the original firmware for it to function? I dont have a backup of the original firmware and it looks like it is specific to the phone in this country.
Thanks
Edit 1:
V12.5.2.0 RKUCNXM (CHina) doesn't detect SIMS
V12.5.2.0 RKUEUXM (EU) doesn't flash at all with SP flash (fails after 100% DA right at the beginning)
V12.5.9.0 RKUINXM (India for 10 Prime) keeps rebooting after a few seconds in MIUI setup screen)

This kind of problem also happened to me. I tried to update my Redmi note 10 sunny (Global) via MiFlash from 12.0.2.0 to 13.0.10.0 but after the flash my phone always reboot back to recovery and says "NV Data is corrupted" . So I had to flash that old 12.0.2.0 version to get my phone working again.
Update :
By flashing only the IMEI 2 I can make the LTE work on the engineer firmware but when I flash a custom ROM PE, EvoX, LineageOS (after a flash of the latest global firmware):
If I manually flash the modem firmware MOLY.LR13.R2.MP.V16.P21 the SIM is not reconized and IMEI 1 and 2 are unknown.
If I leave the modem done for the ROM the SIM is recognized but no LTE, phone call, etc
So... it's still not really solved, I found this solution on treads for the redmi note 9 https://forum.xda-developers.com/t/...nally-first-method-to-fix-1-slot-imei.4258977 and https://forum.xda-developers.com/t/...-in-merlin-redmi-note-9-redmi-10x-4g.4258779/
The PE Rom of the redmi note 9 is visibly compatible with the engineer modem and that's probably why it works with this phone but not the redmi note 11S.
Original Post :
Summary:
I can't get LTE or 3G to work, I tried with several SIM cards that work on other phones.
The problem happened after a formatting and then a complete Flash of the phone with SP Flash Tool to get out of a Hard-Brick.
Issue:
With the Miui ROM, the phone starts directly in recovery and displays nvdata corrupted (doing a "Wipe data" doesn't change anything).
I tried to flash the nvdata,nvcfg,nvram,proinfo,persiste,protect1,protect2 of another Redmi note 11s with mtkclient I manage to start but the SIM card is not recognized and the modem is in unknown version.
On the engineer rom by not flashing nvdata, nvram, etc the modem is in the right version but there is no IMEI and I have no access to the internet and can neither make nor receive calls and SMS.
On the engineer firmware with Modem meta I can flash the original IMEI and the calibration parameters of LTE, WCDMA and GSM retrieved by myself from a redmi note 11s on which the network works with the engineer firmware as with MIUI and after all that I can receive calls but not make any, I can have EDGE but not more and the settings continue to mark "no service" and "radio off", the IMEI and correctly displayed in the settings and when I accept a call the HD logo is displayed, the VOWIFI works and allows to make, receive calls and SMS, note that the serial number displayed in the settings does not seem to be the right one, Everything else works.
On a custom ROM it is identical to the engineer rom.
Context:
My phone ended up in a Hard-Brick following a problem in the unofficiall pixel experience custom recovery (impossible to access fastboot, recovery and system after an "adb reboot fastboot" but Brom mode is accessible).
I used mtkclient to disable the Brom mode protections, I then flashed the firmware V13.0.3.0.SKEEUXM with SP Flash Tool but by ignorance of the software I used the "format All + Download" mode (which has the effect of formatting all the partitions including nvdata, nvcfg, nvram, proinfo, persist, protect1, protect2).
Then I was able to boot but the phone enters directly in a bootloop with nvdata corrupted which is displayed in the recovery, I tried a data wipe but it does not change anything, I used mtkclient to reunlock the bootloader and make the tests that I described in the problem part.
The phone is under warranty but I had unlocked the bootloader, the problem being due to this unlocking, the phone will certainly be considered out of warranty and if they follow their policy in french they will not repair it and the shipping will be at my expense.
After unlocking the bootloader with mtkclient:
I flashed V13.0.7.0.SKEMIXM, flash the unofficial custom rom of Pixel experience 13 with its boot.img, reflash the nvram, nvdata, nvcfg, proinfo, protect1, protect2 from my phone when there was "corrupted nv data" and wipe data with custom recovery.
Pixel Experience works really well, The SIM card is recognized, it shows my operator, baseband version but there is no 4G, SMS and IMEI, IMEI SV is unknown.

a box is a hardware tool to fix imei and other stuff in phones, some repairs have it

There is no way to do it without hardware tool ?
and I don't really understand what you are talking about, can you give me more detail ?
@tutibreaker I updated the original post you could read, even after flashing the IMEI with modem meta there is still no 4G volte and SMS whether on the engineer firmware or the firmware V13.0.7.0. SKEMIXM with pixel experience, SIM and operator detection, baseband version, IMEI, phone number works as it should.
I don't know enough about meta modem to know which option/procedure would make 4G, volte and SMS work again.
nvram, nvdata, nvcfg... from my friends redmi note 11s still doesn't detect the sim card and meta modem can't connect with.
I really need some help please.
I updated the original post again (and again), If someone could help me it would be really nice.
To summarize now I managed to restore the LTE on engineer firmware but not on custom ROM (PE, EvoX, LineageOS)
I have the same problem you can flash gsi but use gsi is sucks
Did you manage to fix it?
