Hi XDA community
I recently flashed AOSP & TWRP on my 2ram 32gb Moto E6 plus XT2025-1
I used the ROM for almost a month and everything worked ok.
Then for personal motives i decided to sell the phone and i tried to flash the stock ROM on it, but the problem here was that i used
SP-flash tools and selected the option 'Format and flash' so when the phone booted i couldn't select any SIM card, the baseband version got erased even when i try *#06# the window only display the serial number but nothing else (i tried 5 different SIM cards) and then i flashed the original stock ROM from the Motorola website using the 'Rescue Assistant' software, and same problem, no SIM no Baseband nothing, so i flashed the stock ROM that worked for me which was AOSP 10, but the same problem appeared, i've also tried to 'repair' my IMEI with the MTK engineering tool but there's no 'CDS' radio option, using "MAUI META" flashing all the "Moto E6 plus" baseband files i've downloaded on forums, flashing stock ROMs for my region, i've also seen that some people use a "box" but i don't have one so i would like to know a software solution for this please
PS: When i boot in fastboot and retrieve the barcodes the IMEI appears, and even when i type 'fastboot getvar all' the baseband version appears too, also i made a "TWRP backup" of the custom AOSP and that custom recovery loads the IMEI and baseband version but the "telephony" modules are inactive, i can't "touch" or select mobile network + the phone keeps displaying "No SIM", the phone hasn't received any physical damage (yet).

Hello,
My phone: GSMART Roma R2 (Rooted)
I know there are a lot of threads how to restore IMEI but none of them worked when I dial up *#06#, it shows message with two lines containing "null".
I was using MIUI rom for a while and suddenly after I rebooted phone SIM was no longer recognized (before reboot I was playing with SWAP couldn't make it work so I uninstalled BusyBox (could that cause the issue?))
I already tried:
Engineering Mode: Displays "AT command is failed to send"
Terminal Emulator: Doesn't work
MAUI 3G: Flashing new IMEI changed nothing.
MTK Droid Tool - Changing IMEI did nothing.
SN Writer: Writing new IMEI changed nothing BUT when I choosed to read IMEI it successfully displayed both IMEI in the textbox. (So it looks like the IMEI actually is registered on the phone but phone doesn't seem to use it)
Manually writing MP0B_001 to NVRAM: Nothing changed.
I have used backup in CWM recovery to stock ROM, didn't work, then I did factory reset, didn't work, flashed back the stock recovery and installed update from Gigabyte site, didn't work. So basicly now my phone has stock rom, stock recovery, factory reseted and is rooted.
Thank you very much for any answers because I just fell hopeless about fixing my phone
I fixed it using solution here: http://forum.xda-developers.com/showthread.php?t=2599459
Scroll down to post with NVRAM backup, I used that backup to fix it and then just changed the IMEI numbers to my IMEI numbers.
So i recently decided to unlock my LG G5 H850 bootloader, installed TWRP, backed up everything I could, rooted my device. Thought why not update to Nougat so I wiped my phone and installed LineageOS. I didn't like it to much so I wiped again and installed Fulmics ROM. After flashing this ROM I noticed that my mobile data could not be used so I thought it was a simple bug wiped and flashed again. Switched back to LineageOS then stock still with no mobile data. I am currently on the Fulmics ROM realizing that I no longer have an IMEI number in my phone. In Settings>About Phone>Status my phone number, IMEI and IMEI SV all show as "Unknown." Typing in *#06# comes back as "null."
I have looked all over the place, tried different things such as going to 6.0.1 and installing some modules to change IMEI from xposed but they always crashed. I've looked at fourms from other websites, downloaded exe programs onto my pc. I cant figure out a way to get my IMEI back. This is my main phone, I cant switch the sim card to my Nexus 5 unless i have a sim card adapter so it fits.
Any help would be great since i never knew this was a possibility.

Try and restore your EFS partition from TWRP with the first backup you made.

In order for it to see the phone you need to enable the port check option in the hidden menu first it's under "SVC MENU", after doing this plug your phone into your pc and select File Transfer.
After doing this you will see in the device manager the new usb com port and you will be able to use EFS Professional with it.

I had this problem too (loosing IMEI) after flashing Nougat 7. For me helped flashing bootloader for Nougat 7. IMEI restored.

I have this problem with my AT&t LG G5 H820. Phone is not rooted, as if you didn't already know after reading the first line. I don't know how or what I did but can't figure out a fix.

same prolem .unrooted lost imei
If phone on Marshmallow (MM, Android 6), ROM (from 10a till 10g version), bootloader must be from Marshmallow. If phone on Nougat (N, Android 7), ROM (from 20a till 20d version), bootloader must be from Nougat. If ROM from one system, bootloader from another, will be lost IMEI.

Hello,
I have an Elephone P8 (2017). After flashing an ROM image to the device, the NVRAM was overwritten and the operating system reported no IMEI. To fix it, I used the SN writer tool to re-enter the IMEI numbers, MACs and serial and re-installed the latest stock ROM from Elephone.
The IMEI numbers are back again but for some reason, the mobile network connection is only available for a limited time after booting. 20-30 minutes later, no mobile network is available anymore until I either reboot the device or toggle the SIM to be used for the mobile data connection.
Has anybody an idea how to get a stable mobile network again?
Is there possible that anything else is wrong or missing in the NVRAM beside the IMEI numbers?
This sounds like you flashed the release-version 20170722, not the first update 20170831.
Recheck. If in doubt, format whole device with SP-Flash-Tool and reflash 20170831.
Hello,
I installed the 20170831 stock ROM but "about the phone" in the android settings lists a baseband version with an older data:
Base-Band-Version: MOLY.LR11.W1630.MD.MP.V9.3.P10,2017/06/26 09:07
Kernel-Version: 4.4.15 [email protected] #1 Thu Aug 31 11:28:07 CST 2017
Build-Number: Elephone_P8_V11_20170831
IMEI-Numbers: 3598500800XXXXX
IMEI-SV: 78
SERIAL: ELEE800....
Same problem

Hi GoaSkin,
I have the same issue than you. I also overwrote my NVRAM and restored my IMEI with SN writer tool.
(If anyone think he bricks his elephone p8 (2017), he should try to flash a test version (he worked for me, when all the other version didn't work) then reflash with a recent version. )
SMS and 4G Internet works fine but phone call (3G/2G) don't work :crying:. (sometimes when I reboot my phone, it works again but it is rare).
I have the same version of Base-Band than you.
I will try to flash other version, to test if it works for me.
I'll let you know.
I found advices in other forums that people have similar problems on other devices using "Moly Baseband". They managed to solve this issue by using a different version of the moly baseband file when using the IMEI tool.
When you use the IMEI tool, you need to submit the baseband file beside the IMEI numbers and MAC addresses you enter. The baseband file comes with any firmware image. I don't know which baseband version was installed before I bricked the NVRAM partition but it is possible that the pre-installed version was a different one to that which comes with the (newer) firmware updates.
Maybe it is worth to try to downgrade the baseband version which comes with an old firmware image or to try if it is possible to use a baseband image that comes with the firmware of a different device also using Moly baseband.
Furthermore I found out using analysing tools that the phone is still able to get some information of the GSM network. Possible the mobile operator closes the network link caused by bad network requests.
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.

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?
