IMEI 0 after Fastboot erase commands - Lenovo K6 / K6 Power / K6 Note Questions & Answers

IMEI 0 after Fastboot erase commands - Lenovo K6 / K6 Power / K6 Note Questions & Answers

I have Lenovo K6 Power K33a42 which had network issue. Either of the sims worked at any time on whichever sim the mobile data was enabled. I referred XDA forums and based on suggestions ran these commands
adb reboot bootloader
fastboot erase modemst1
fastboot erase modemst2
fastboot reboot
After which networks of both sims weren't connecting. On checking IMEI 1 AND 2 found it was 0. The baseband is however intact.
I have done factory reset which didnt help, even flashed through Rescue and Smart Assistant tool yet the IMEI 0.
I am pretty sure many had faced this and there could be working solution, kindly share the solution to restore IMEI number.
Note that, I have the phone box which has IMEI number.
There could be many ways of dealing this, each and every one of yours solution may help. Kindly share.

XT1642: IMEI show as 0 (even after reflashing to original unrooted)

Hi,
I have G4 Plus XT1642 (retapac). It came shipped with 6.0.1 MPJ24.139-48 preinstalled.
Well i flashed, deleted, maybe bricked and then made it work again with the latest version i wanted to have (139-63) and then rooted it. Everything worked/works, but the wifi mac shows as 02 000000 or something (but no problem with that, wifi mac is fixed with some earlier backup i have, it also gets fixed when i flash to original).
But the worst thing is: Both IMEI show as 0. In the setting menu, and also when dialing the command *#06# (Both IMEIs show 0).
It gave some errors at fastboot because of "downgrade" or so, but i think that's not the issue.
I tried everything, also reflashed to my original version (ATHENE_MPJ24.139-48_cid50_subsidy-DEFAULT_CFC.xml.zip). Everything is fine, wifi mac displays as original also, but IMEIs still are 0.
No matter what I do, both IMEI show as 0, and SIM cards don't work ofcourse (they work, show carrier names etc but don't get accepted, ---> "emergency calls only", because IMEI is 0 i think.
Before you ask: No i don't have a very early TWRP backup from before flashing, deleted it because I had later backup I though everything was working, didn't try any SIM at that time.
How can I fix this? Is there any hope?
What gives me the little hope: At "boot thing" when I type fastboot getvar imei, it shows the correct imei! It doesn't list the second sim though.
Thanks in advance!

Yes. Did exactly that. Flashed the files of XT1642_ATHENE_6.0.1_MPJ24.139-48_cid50_subsidy-DEFAULT_CFC.xml.zip ... with the commands
Code:
fastboot oem fb_mode_set
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash dsp adspso.bin
fastboot flash oem oem.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash system system.img_sparsechunk.5
fastboot flash system system.img_sparsechunk.6
fastboot flash system system.img_sparsechunk.7
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot erase customize
fastboot erase clogo
fastboot oem fb_mode_clear
fastboot reboot
Showed some "errors" at fastboot at some, but I think that was normal. And flashing worked.
But in the end, both IMEI are still 0.
Even reflashed the NON-HLOS.bin. IMEI numbers are still 0.

Additional information:
The original version this retapac XT1642 G4 plus came shipped with was MPJ24.139-48.
I then wanted to update to the latest non-nougat version, which is MPJ24.139-63.
I could not update directly to MPJ24.139-63 from MPJ24.139-48. (Because the internal recovery showed error, that flashed version must origin from MPJ24.139-23.4).
So I overflashed (with fastboot) to MPJ24.139-23.4. So the version then was even lower than it came shipped with lol. Then from MPJ24.139-23.4, used the internal recovery (not TWRP), to apply the OTA update file MPJ24.139-63. Since then the Wifi mac was 020000000 or something, sometimes random wifi disconnects, and imei 0. After going back to original again, wifi mac is fixed, but sim imei numbers still are 0.
Edit: not sure if the imei and wifi errors accured since MPJ24.139-23.4, or after the OTA update file, or sometime inbetween because i deleted something in TWRP.

Try removing oem fb set command
If it doesn't work then flash nougat then use 6.0.1 custom ROM
Edit fb_mode_set

Flashed everything again, without the fastboot oem fb_mode_set (MPJ24.139-48). Both IMEIs are still 0, everything else is fine though, original wifi mac.
---
Then took original over the air update it offered me (NPJ25.93-14). Installed without problems.
But, guess what.... it made things worse.
Now i am on NPJ25.93-14, the IMEIs still are 0, and the wifi mac address is at 02:00:00:00:00:00 again.
What I noticed is, in settings it shows the IMEI SV (Slot1) and IMEI SV (Slot2). They both changed to 08. I think they were 03 or so before.
Edit: In the boot recovery thing it says the usual stuff:
Battery OK (Charging)
flashing_unlocked
Software status: Official
...
So... updating to Nougat did not help, made things worse (wifi mac weird again, IMEI still 0).
Any other ideas?

Ruined my modem partition... Please help

i downloaded factory image of 7.12.29 oreo
i used flash_factory.bat
it reflashed partitioning
apparently it had a command "fastboot flash modem_a NON-HLOS.bin"
the NON-HLOS.bin file does not exist in images folder nor in any fastboot rom
now i dont have any connectivity... signal.. wifi etc..
can anybody provide NON-HLOS.bin file for the A1

Hello,
Inside the fastboot ROM file "tissot_images_7.12.19_20171219.0000.00_7.1_d39fa89aaf.tgz" (Nougat 7.1.2) ... in the file "flash_all_lock_crc.bat" for example, these lines appear:
fastboot %* flash modem_a %~dp0images\modem.img || @ECHO "Flash modem_a error" && exit /B 1
fastboot %* flash modem_b %~dp0images\modem.img || @ECHO "Flash modem_b error" && exit /B 1
It seems that the file is called "modem.img", not "NON-HLOS.bin".
May be?
Regards!
PS: Sorry for my English!

i managed to flash all images from fast boot to partitions manually step by step
except something called fsg and persist partitions

Wow! The file NON-HLOS.bin is the modem for other Xiaomi phone. May be you use a batch file (flash_factory.bat) for other phone, not Mi A1. Please use Mi Flash with right rom.

this is method not working

Can you please report, if it works and if should not work, please attach the terminal/ shell outpout of the failed flashing attempt here.

Replace the IMEi with UR Own IMEI . if not it's illegal to use this QCN
Password : testnreport
if you don't know how to change IMEI Using hex editor , try my method . DO NOT use QCN to restore .
(hex and imei provided in order for u to find n replace)
i lost my imei n spent me about 6days n 8 hours per day to find a way to fix it .
actually it's easy to fix the problem .
My own method
1. download the older rom (7.8.23) Link
2. Use flash_all.bat
3.reboot into fastboot mode , erase modemst1 and modemst2 .
fastboot erase modemst1
fastboot erase modemst2
4. reboot
5. go to phone , enter *#*#717717#*#*
6.got to settings enable USB Debugging (ADB)
7. disconnect your phone n connect it back
8.Use WriteDualIMEI(W+G_eMMC) Remember run as administrator , enter your IMEI .
9.if success , go to phone enter *#*#717717#*#* to disable the diag port
10. reboot
Done .

[Guide] How to solve problem IMEI 0 in Moto G5 Plus

Hi guys , this is one of my first contributions were i will explain how to recover the IMEI that some of us lost when flashing a 8.1 rom (in my case Pixel Experience) and when tried to return a stock we got the surprise that the IMEI had been erased and showed 0. Well, to the point:
You will need:
- TWRP 3.2.1: http://www.mediafire.com/file/8tz88d2y2v2i6ih/twrp-3.2.1-0-potter.img.zip
- Scripts:
Flash stock rom: http://www.mediafire.com/file/c0s90358uub78l4/Flash_Moto_G5_plus.bat
Relock Bootloader: http://www.mediafire.com/file/qn2yiih1zehdcpz/Relock_Bootloader_Moto_G5_Plus.bat
- Rom Pixel Experience 8.1: https://forum.xda-developers.com/g5-...ience-t3704064
- Rom stock of your preference (tested with NPN25.137-83): https://mirrors.lolinet.com/firmware...ficial/RETAIL/
- And patience; P
Step by step:
1. Flash TWRP.
2. Flash Pixel Experience rom if we haven't flashed yet.
3. Turn on phone with flashed rom to obtain network signal
4. Here we will get the IMEI and only have 3g signal, so we need to restart the phone in bootloader mode and type in fastboot "fastboot erase modemst1" and "fastboot erase modemst2", these two command will give us IMEI and 4g signal.*
5. Turn on Pixel Experience again to obtain 4g(verify it pls), shutdown and enter bootloader mode.
6. In this point -and the most important to obtain IMEI and signal again- we must flash our phone with desired a right stock rom, execute fastboot command(if your want yo relock bootloader or not use the right posted above), just don't write "fastboot erase modemst1" and "fastboot erase modemst2"(in the scripts above are erased if you want to execute all in one time), because if we don't erase those two commands we will not obtain IMEI and signal.
7. We wait until finishes and write "fastboot reboot" and wait to turn on.
Y voilà!! you now have your phone with IMEI and bootloader relocked!!!!
* NOTE: It's very important to turn on the phone once flashed Pixel Experience to obtain IMEI info and turn on again to obtain 4G.
** voLTE not working.
Well I hope this guide has been as clear and understandable as possible, if there are any mistakes let me know since i'm a noob in this. Oh and sorry for my bad english lol.

All your links are dead!!

Sorry,
But 4g and VOLTE is not working

I also managed to get LTE back, but also no volte. I'm on T-Mobile usa

I am also on T-Mobile USA and can only get 2g. I have flashed the modem files mentioned but that didn't work. Any suggestions.

Your bat files are all deleted. Can anyone tell me what fastbook commands we use?

Yeah, seems we can only get 4g at this moment, because we are using generics modems from the Pixel Experience. I think we will need to wait until Google deploys 8.0 with the official modems to obtain voLTE

I'm still just getting 2g. Anyway to get to 4g. I've fastboot flashed the modem files mentioned (erased). Thanks. T-Mobile USA.

Hello, @Castell93 and thank you very much for this guide. I just want to ask you a question: should I be cautious to go fastboot stock if I'm in this situation: latest 8.1 oreo, then twrp flashable stock nougat (or debloated), then fastboot stock ? I would like to try to go to stock and re-lock bootloader so I can get new OTAs. But now I once went to Oreo roms, I'm afraid to go back to fastboot stock. Hope you can help me.

Thanks for this guide!
Successfully restored LTE on resurrection remix ROM with this guide. Didn't even have to go back to stock. Thanks a ton! I was really struggling with 3g

Step by step:
1. Flash TWRP.
2. Flash Pixel Experience rom if we haven't flashed yet.
3. Turn on phone with flashed rom to obtain network signal
4. Here we will get the IMEI and only have 3g signal, so we need to restart the phone in bootloader mode and type in fastboot "fastboot erase modemst1" and "fastboot erase modemst2", these two command will give us IMEI and 4g signal.*
5. Turn on Pixel Experience again to obtain 4g(verify it pls), shutdown and enter bootloader mode.
6. In this point -and the most important to obtain IMEI and signal again- we must flash our phone with desired a right stock rom, execute fastboot command(if your want yo relock bootloader or not use the right posted above), just don't write "fastboot erase modemst1" and "fastboot erase modemst2"(in the scripts above are erased if you want to execute all in one time), because if we don't erase those two commands we will not obtain IMEI and signal.
7. We wait until finishes and write "fastboot reboot" and wait to turn on.

The same happens to me, I can not get the imei, or the 4G in any step, I only have 3G. After executing the commands, I have no signal, and when searching for a signal manually, it signals me an error.
Me pasa lo mismo, no consigo obtener el imei, o el 4G en ningún paso, solo me queda en 3G. Despues de ejecutar los comandos, no tengo señal, y al buscar señal manualmente me señala error.

Hi guys , this is one of my first contributions were i will explain how to recover the IMEI that some of us lost when flashing a 8.1 rom (in my case Pixel Experience) and when tried to return a stock we got the surprise that the IMEI had been erased and showed 0. Well, to the point:
You will need:
- TWRP 3.2.1: http://www.mediafire.com/file/8tz88d2y2v2i6ih/twrp-3.2.1-0-potter.img.zip
- Scripts:
Flash stock rom: http://www.mediafire.com/file/c0s90358uub78l4/Flash_Moto_G5_plus.bat
Relock Bootloader: http://www.mediafire.com/file/qn2yiih1zehdcpz/Relock_Bootloader_Moto_G5_Plus.bat
- Rom Pixel Experience 8.1: https://forum.xda-developers.com/g5-...ience-t3704064
- Rom stock of your preference (tested with NPN25.137-83): https://mirrors.lolinet.com/firmware...ficial/RETAIL/
- And patience; P
Step by step:
1. Flash TWRP.
2. Flash Pixel Experience rom if we haven't flashed yet.
3. Turn on phone with flashed rom to obtain network signal
4. Here we will get the IMEI and only have 3g signal, so we need to restart the phone in bootloader mode and type in fastboot "fastboot erase modemst1" and "fastboot erase modemst2", these two command will give us IMEI and 4g signal.*

7. We wait until finishes and write "fastboot reboot" and wait to turn on.
Y voilà!! you now have your phone with IMEI and bootloader relocked!!!!
* NOTE: It's very important to turn on the phone once flashed Pixel Experience to obtain IMEI info and turn on again to obtain 4G.
Thanks for the htcman solution

LeEco Le 2 x526, no signal, SIM is detected

Hello,
I am flashing the lineageos with the official instruction. The rom is installed (partition was decrypted), but I have no signal.
After a long research on the net and various instructions and tips. My two IMEIs disappeared (sim cards were then no longer recognized).
Finally I have a stock rom with Qfil installed (13s). I was then able to restore the IMEIs through the AT Port Menu via Qualcomm IMEI RepairTool. The SIM cards are recognized again but do not dial into the network. I have also a baseband version package.
In the *#*#4363#*#* menu there were all frequency bands to choose from, but I can not select one. The error message always appears ... [unsuccessful]
Maybe someone else has a tip?

Solved!! I need modem files for POCO M3. (NV data is corrupted)

Just for my curiosity I was trying to change my device's IMEI. I used qfil to backup my qcn file. Then I rebooted to fastboot mode and ran the following command:-
fastboot erase modemst1
fastboot erase modemst2
fastboot erase fsg
For just in hope to erase the current partition and restore qcn.
But, after doing this my device isn't booting. It's just bootlooping to Recovery mode (stock).
Full firmware flash using MIFlash is even not working.
Bootloader of my POCO m3 is unlocked.
Please help me how to recover my device. OR kindly provide the three files of your POCO M3 by pulling it via adb.

Experts also avoid trying IMEI, so I don't know what you were watching.

Thankyou for the reply! I have successfully repaired by rooting---resetting the efs--- and then restoring the qcn. My device is back to life now!

After flashing my poco is doing the same thing it's booting to recovery with an corrupt nv message
can you please share more information how you fixed this.
