Hi,
I own Lenovo K9 Note having model number L38012. I know there are many threads like no IMEI, no signal, etc, etc, etc but none of them proved to be helpful. Moreover, I googled everywhere about the problem but I got nothing. The device I own seems to be very new. So, I need help.
The problem is that when I reset my device, it became FRP locked(in starting I didn't understand what was that since I'm a newbie). I flashed stock ROM but nothing happened. THEN I ERASED ENTIRE FLASH FROM PARTITION MANAGER IN QFIL TOOL . My phone became hard bricked but somehow I recovered from it and also now I can use my phone like before but the problem arose that I ended up with no IMEI, NO SIM CARD I somehow restored IMEI by using the QCN file of another device (Mi A1) since I didn't find the QCN of mines on google as mines is a very new device. I used the IMEI Rebuilder tool and edited the IMEI code from the downloaded QCN with my device's IMEI. In this way, I got my IMEI back but NO SIM CARD DETECTED AND WHEN DETECTED AFTER REBOOT, IT SAYS NO SIGNAL FOR BOTH SIM CARDS. ALSO, ACCELEROMETER STOPPED WORKING I tried several methods like:
1. fastboot erase modem (and modemst1, modemst2, fsg, cache, userdata, PERSIST)
2. flashed others PERSIST.img file found on different threads
Somehow recovered sensors like proximity, light and compass by flashing any persist.img but still NO SIGNAL, ACCELEROMETER NOT WORKING BUT SHOWING IMEI after dialing *#06#
ALSO, I DON'T HAVE BACKUPS OF SUCH CRITICAL PARTITIONS. I know I did a BIG MISTAKE.
So please can somebody provide me a solution ( or provide qcn dummy for Lenovo k9 note if someone owns such stupid device Also someone can provide me the PERSIST.IMG OR OTHER important partitions of the said device).
The stock firmware doesn't include these critical partitions.
My device specs:
Model: Lenovo K9 Note (L38012)
SoC: Qualcomm Snapdragon 450(SDM450)
Processor: Octa-core CORTEX ARM A53 @ 1.6 GHz
RAM: 4 GB
Please help if possible as I am afraid and I urgently need the phone. Any HELP WILL BE GREATLY APPRECIATED. Thanks In Advance...
Thanks
I somehow recovered the accelerometer by flashing persist.img found on the link https://forum.xda-developers.com/redmi-note-3/how-to/fixed-gyroscope-accelerometer-magnetic-t3522745
Now, the problem is when I insert the sim card, there is no network though IMEI is showing in *#06#
After dialing *#*#4636#*#* and heading to phone information, the radio state is showing OFF and signal strength = 0 in both sim cards.
In fastboot mode, bootloader version and baseband version are showing unknown while in settings baseband version is showing some string.
Thanks
Please someone reply soon

First I'm so sorry if my question is similar with another threads. But I'm pretty sure I have been looking for the answer around the internet and of course XDA developer for a week. I follow every guide and method I found. But it still not answer of my problem.
I flashing camera driver I've got from my friend backup using TWRP backup. Actually I only need to choose uboot only to install. But I'm in hurry so I accidentally choose everything includes NVRAM. Since then I've got wrong IMEI on my phone because the IMEI overwritten with my friend phone. But it's not a problem because I can restore my original IMEI with MTKDroid & Tools.
And the problem is my IMEI is now back and corrected. But there is no network detected on the phone. SIM card detected fine. When I go to EngineerMode by pressing *#*#3646633#*#* and open Radio Information on CDS I saw IMSI field was unknown and Radio Status is turning on and off rapidly.
What I have done is :
1. Full flashing with the stock ROM via SP Flash Tools.
2. Change the IMEI with MTK Droid Tools
3. Change the IMEI with AT command ... echo 'AT+EGMR=1,7,"myIMEI1"' >/dev/pttycmd1
No result. IMEI is correct but no network.
I believe this is not a hardware problem, so please help me to solve this problem. Because it's my only phone to communicate with my whole families. I really appreciate with your help. Thanks.
Good day People,
I don't want to beat around the bush so, I installed customROM works fine. then I reverted back to stockROM then IMEI is gone.
I tried the Engineering mode thing, I tried multiple IMEI Writers non of them works for me. I always have this error "meta mode entry fail" for some reason I don't know what to do.
I do have an MTK Based phone its dual Sim.

I WHOLE formatted my Cherry Mobile Fuze Q390 (MT6582) with SP Flash Tool. Then I flashed the official firmware of this device with SP Flash Tool. I don't have any backups because I am reverting to stock. Now the phone works fine but it does NOT detect the SIM card. Also, the IMEI is shown as "INVALID" for both SIM slots when I input *#06#. When I try to fix IMEI from MTK Droid Tools it shows (ERROR : pttycmd1 device NOT found!). Also, MTK Droid Tools shows (Baseband V -----). I am sure the problem is that when I formatted the phone it wiped the NVRAM region too. So the device has no baseband or radio files right not and also the data/nvram/md folder has nothing in it. Although, WiFI still works perfectly except the annoying NVRAM Warning that I kept on seeing when ever that I wanted to connect to a network. Now the official firmware of Cherry Mobile Fuze Q390 does not contain any nvram.bin file. It does contain the BPLGU file but I can't seem to modify IMEI with SN Write Station, Maui META 3G, IMEI&SN Writer V1.5.3 and etc. I tried using the MTK Engineering mode mode also and tried to write it using the AT+ code but it keeps on saying failed to send command. Probably the SN Write Station, Maui META 3G, IMEI&SN Writer V1.5.3 and etc. only modify the IMEI when the baseband or radio files are already present on the phone. So I think the only way out for me is to flash a nvram.bin using SP Flash Tool or Flash nvram.bin+nvram.tar to MTK Droid Tools which I don't have. Any ideas whether I am on the track or not? If I am, then how can I get the IMEI back on my phone. As you people can see that I have tried a lot of things, so please suggest/advice accordingly and any help would be greatly appreciated.

a114 user mt6582
hi dude did u resolve that ..now i got that problem man ..the thing which happend to u turned to me just formatted completley and now suffering...searching solutions for two days....jus tell me if u find the solution dude ... email to [email protected]
we have a same problem.
I fixed my phone (FUZE) ... .
just flash the phone in Firmware with "SEC_RO" file.
Fix IMEI, at least for MT6589 Gigabyte GSmart Aku A1 (if *#06# show Invalid IMEI):
Call *#*#3646633#*#* Engineer mode, Connectivity, CDS Info, Radio Info,
Phone 1: AT+EGMR=1,7,"myIMEI" <send>
Phone 2: AT+EGMR=1,10,"myIMEI2" <send>
Hello @phaw16, @nandhu.crab19 : Can you resolve that problem?
I have the same here my phone is Blu Dash 5.5 D470u with mt6582 processor.
The meta mode is failed to connect. Drivers are ok.
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 sucessfully rooted this device maybe 2 weeks ago... however bricked it trying to modify build.prop ( i still dont know how to mount system rw on this device)
so when i didnt have the firmware backed up i kind of was stuck so i ordered a junk phone off ebay same model but imei was blacklisted i did a full backup of the firmware and was able to unbrick my original device.. however the problem i face now is that it also copied the IMEI number from the ebay one onto this one.... ive tried numerous imei changer apps , tried clearing nvram nvdata, all that stuff but still it has the imei from the ebay device..... Im not asking how to change imei number persay because i know that is frowned upon and iilegal in some countries... but is there any way to restore the devices actual imei??? its a MT6833 ( mediatek dimensity 700 5g k6833) TCL t767w (30 XE 5g)
do i need to erase all paritions before flashing to get my imei number back? where did i go wrong? when flashing the ebay phones firmware should I not have flashed a certin partition pertaining to the imei ?
any insight or suggestions i thank you in advance
I can't help you with your question, but if you don't mind how did you root the phone? I'm trying to do this myself with no luck. My phone doesn't boot in bootloader or fastboot. It used too when I first bought it but after ota update it went away
with correct drivers installed (mediatek) you can use mtkclient gui or mtk meta tool... basically have your phone turned off have the program running on computer and plug your phone into the pc and it should automatically detect it or you can hold down all the buttons and mtk client gui should pick it up, load it up, from there can unlock bootloader and , backup firmware, flash firmware and so on
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?
