THL W8S : IMEI invalid after few flash - Android Q&A, Help & Troubleshooting

Hello everybody,
I bought recently my thl W8S, and I was experiencing some troubles with the battery charging (taking 10 hours) and my GPS connection.
So I decided to flash it via CWM. But I'm very new in the flashing and all this stuff. I tried a lot of things to get CWM , even thing I didn't know.
The problem of my IMEI came out atfer I installed this :
http://forum.xda-developers.com/showpost.php?p=19319421&postcount=23
The recovery installer apk, I just click on it and when my phone rebooted, I didn't have any access to my SIM management, no more coverage of course.
I tried the *#06# and my 2 IMEI are just marked as "INVALID".
Since yesterday I tried few different operations to get if fixed but nothing is working.
I tried to use the engenering mode (menu CDS, Network information) and send the AT command with the IMEI but I got an error message : AT command is failed to send.
Then I tried to recreate the MP0B_001 file with some tools I downloaded. And I put it in the right folder (/data/nvram/md/NVRAM/NVD_IMEI/MP0B_001) instead of the old file. I reboot my phone, still the same trouble.
I'm kind of desesperate right now.
Any thoughts / ideas?
I can't find the stock rom to try to flash it with Odin ..
Thank you

Hello
I tried to do this but I can't send any AT command , error message is : AT command is failed to send
Any other idea please?

Hi, Did you finally managed to fix the imei issue? I have the exact same problem.

I have the exact same problem. Who successfully solve this problem?

If you didn't back up your efs partition then the only other allowed way is to send it back to the oem.

[Q] IMEI null and SIM not recognized, nothing works

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.

[Q] Acer Z200 back to stock rom

Basicly loaded a dual sim rom on a single sim Acer Liquid Z200.
was helped so far in this thread: http://forum.xda-developers.com/and...ms-cwm-root-acer-liquid-t2960787/post59482099 by @Shreps, but somehow i got this message that due to the 10 post rule i wasnt able to post anymore.
Downloaded the last zip file, but CMW doesnt seem to recognize my SD card.
Tried to load the rom with adb using sideload, but get the message cant find device.
Is it possible to load another version of CMW, mount it with USB and flash the zip file from the pc? And can i use any CMW file or are the custom made for each type of phone/brand?
Any other suggestions, got no clue what to do now
edit 18-3-15:
Tried to re-load CWM with Smart Phone Flash Tool and got this PMT changed for the ROM; it must be downloaded
Update:
Did a format of the device using Flash Tool, MTK USB poort was loaded and was able to flash the ROM for dual SIM.
@stef951
Try to flash this firmware from a Recovery :
update-Acer_AV0K0_Z200_1.012.00_EMEA_GEN1S-sds.zip
It's the stock firmware Single SIM EMEA GEN1s, you should back to your original firmware.
Click to expand...
Click to collapse
used recovery to install the firmware for sinlge SIM.
However now stuck with IMEI issues.
Used Mobile Uncle Tool and MTK Engineering to get into Engineering mode, but get this message: "cannot find engineer mode app"
*#*#3646633#*#* doesnt do anything. Possible that Engineer mode isnt installed? And is it possible to install it on my device?
Tried to load IMEI with MTK droid gave me a message "Changes will come into force after reset", but nothing changed -_-
Any other options on this IMEI matter.....?
Finally found a solution to enter Engineering mode, type *#*#2237332846633#*#*
When i try to change the IMEI with AT commad get a message AT command is failed to send
Tried Uncle tools, but unaible to acces engineering mode with this app.
I can enter a valid IMEI in MTK tools, but after reboot its still unknown.
Tried to copy a new MP0B_001 file to the NVD_IMEI folder
but all failed :crying:
Still searching for the solution, but if someone over here can help me out it would be appreciated.
Phone is not reading SIM card neither, is this because of the IMEI issue?
Acer Z200 Working again!!!
GOT MY PHONE BACK TO LIFE!!!
Lost the serial number and IMEI, had to write them back to NVRAM using Maui META tool.
Tutorial how to found on http://www.gizbeat.com/6058/how-to-...-for-mtk6582-mtk6572-mtk6592-mtk6589-mtk6595/
In the attached ZIP the files i used for the Maui META tool
Android_Gadget_CDC_driver, CDC driver didnt got installed so had to do this manually.
MTK6572 database: BPLGUInfoCustomAppSrcP_MT6572_S00_MOLY_WR8_W1315_MD_WG_MP_V1_P3_1_wg_n
If you have the serial and IMEI number, go to method B under Restoring Values and add the manaully.
When loading the MTK6572 database i also got a warning: execution warning nvram database file is inconsistent with target load
Ignored the warning and just writed the serial and IMEI to the device.
Disconnected, rebooted and got a working serial and IMEI.
So happy that the damn thing got working again.

flash back to stock recovery v3.09 or v3.22 open up adb and factory ports *#7678# download and install QPST configuration and choose the port of your phone, select start client and "software download" then press restore tab.
You will have to find the backup file (nv.qnc) made in c:/nubia backup folder. if u need any help pm me
I, i just tried it with my (nv.qnc) file because i'd lost my IMEI and MEID. It worked, but since when I enter my PIN code, the phone boots, but 10 second after it answers pin code again and again. if I try to restore the imei an other time it says "the ESN of the phone does not match the ESN of this file containing RF calibration data".
Could you help me? Thanks!

Fixing IMEI null problem after flashing ROM

Hello,
I have a Lenovo K3 Note (k50t5) that I bought from China.
Since it came preloaded with a lot of bloatware and without an option to update to newer builds from Lenovo, I flashed the Indian ROW (rest of the world) k50a40 version and updated to the latest S121 version.
The problem is that the IMEI got deleted and I couldn't fix it with numerous methods I found in various forums.
I rooted the phone using the CWM method.
I tried using Mobile uncle app, but it doesn't have the engineer MTK option for some reason, only Android.
I accessed engineering mode through the dialer (*#*#3646633#*#*), and tried using AT command but it gave me the common error that it cannot send the command in user mode. Making a space before the + sign just gave me an ERROR, without specifics. I modified the build file from user to userdebug, and now I always get ERROR.
The weird thing is that I get a data connection from time to time, but I can't make phone calls or send SMS. Any help will be greatly appreciated.
I managed to fix the problem! I'm posting this as it might help other people with this problem (invalid IMEI).
Just download an app called "chamelephon" from google play. it allows you to type in your IMEI.
It fixed the problem in 1 minute. Now I can call and send/receive SMS as normal.

Imei Problem

Hello xda users,
Yesterday I flashed a custom rom (Darksense) on my elephone p9000. Everything went fine, that's what I thought.
My imei are changed to 111111111111111 and 222222222222222 , I cant receive sms and calls anymore.
Is there any way to change imei for the elephone p9000 ?
I was looking on engineer mode but...
There's no 'cds informations' on this phone.
Thanks in advance for any help.
reflash the stock rom and then follow the video https://youtu.be/w9POQK3kf6U
Reinstalled the Stock ROM but there's still no 'cds informations'
I'm really lost, cant receive any sms nor call :crying:
http://bbs.elephone.hk/thread-12457-1-1.html#.WBzMwPqLQdU
This method returns me that error: "Execution Warning : NVRAM database file is inconsistent with target load"
Still having the imei problem. My phone is a toy right now.
Can anyone give me some help ?
Been waiting for months now to see if the IMEI can be recovered. At this point it's a glorified PDA...
Moved on to bigger better things...
Managed to fix it !
Thanks to @jay98shankar
1) http://www.needrom.com/download/android-6-stock-20160401/ Sign up and download this (dont download the latest official rom(810) this is the only rom which can help you)
2) Flash using sp flash
3) Go to engineer mode you'll find CDS Information
4) Avoid formating your phone using sp tool just - formating made all this problem

Trid this before but hell, try again.
Same results - after entering AT+EGMR"IMEI" (imei number, not IMEI....) I hit Send AT Command and get " INFO - This command is not allowed in UserBuild"
Still no love.....
@ultramag69
Add a space between AT+ and EGMR.
The command must looks like that:
For IMEI 1: AT+ EGMR=1,7,”YOUR NEW IMEI"
For IMEI 2: AT+ EGMR=1,10,”YOUR NEW IMEI"

+CME ERROR: 100
is displayed...
About ready to throw out the window....
Might just use as a codi remote... This is taking too much energy for a Peice Of Sh!t phone...
Download MauiMeta 3G, install the drivers for P9000. I think you can use the same drivers as SP flash tool. Run Mauimeta, choose something like "flash imei", laod file witch is named MDDB_**********.EDB. Shut down your phone, press on start and turn your phone on. Write your imei into the textfields and flash it. (For me it worked only with Stockrom)
