I have a HDC Galaxy S4 Legend and for now the problem is that it says "SIM is not detected" also I see that IMEI is null.
How I got to this situation? I' really a newbie in all this things, I just wanted to install a new ROM and after reading and searching and trying to install some kind of recovery files I got a recovery menu in Chinese. Because I didn't know what option to choose I selected something after that the phone started to vibrating and doing some noisy signal I just took off the battery cause it didn't stop. So, of course it did something bad, but after
more straggling I found a recovery file that showed me an English menu then I installed the new ROM hopping it will solve my problem. But, it is not. My phone is working fine (really surprising for me), but thew IMEI is null and SIM is not detected.
What can I do?
I tried to write IMEI inside MTK Tools (GPRS option) but it says "Fail to write IMEI due to radio unavailable or something else"
Also I tried to enter CDS Information --> Radio Information and type AT+EGMR=1,7,"MY IMEI" and I got "AT command is failed to send"
Before "doing all phone tricks" I did a backup from recovery menu, I got this file but I don't know if it can help me to restore IMEI.
Please someone help me, I'm so lost and disappointed.
Waited for a phone so long and now cannot use it.

I wanted to sell my Galaxy s2, the guy wanted it to be factory reset, with the original firmware.
I have downloaded GT-I9100_XME_I9100XWKF1 firmware, it worked. But I had the "sim locked" symbol in the notification bar, so I wanted to unlock it.
I downloaded CF-Root-SGS2_XW_OJV_KF1-v4.0-CWM4, and rooted the phone.
Downloaded the Galaxy Unlock app from market place, followed steps 1-3. Phone rebooted.
The unlock didn't work, Instead of a sim locked symbol in the notification bar, I got this stop symbol (like in "no smoking" sign). When I try to go to settings->wireless and mobile network->mobile network, I get "Insert Sim Card to access network services" (sim card is insert correctly, i double checked). When I try to make a call, same message "Mobile Network not Avaliable".
I did some search on the forum, one of the guys said that I should check if the IMEI is matching, I dialed *#06# and got the word: "IMEI", no serial, just that.
I tried to go to Unlock Galaxy app and do a restore efs (step 4), i get the message "You don't have efs save in /sdcard/Galaxy_S_Unlock"
I tried the sim card in a different phone, it works. Tried a different sim in galaxy, it doesn't work.
I tried to do a reset of the device from a backup I had from a month ago, it didn't help, same problem.
What can I do?

Thank you for the reply, I have tried the GSII_Repair, just now, I installed busybox on android device, and followed the steps.
Step 1 was succesful, so was 2.
After trying step 3 i got the message : "You dont have .nv_data.bak and his md5 files, canceled"
I did more research and found out that I have network lock. Punching the code *#7465625# confirmed it.
I tried that tutorial: http://forum.xda-developers.com/showthread.php?t=1369474
to fix it, it didnt work because I didn't have the hex adress 181468 nor 18145C in my nv_data.bin
do not use galaxy s2 unlock, try galaxy S unlock, this one is better but with greater risk but never heard anyone had issue with this. Use this then do the GS repair again.
should this one did not work, i suggest you do odin flash of official roms. Tried flashing the rom 3 times, I was able to fix the same problem with my galaxy tab before doing that. goodluck.
THank you ! *FIXED*
I just used the original Samsung Unlock, and I didn't notice that it had a fix built in. Tried it and it worked !

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.
Thread closed.
Before I start with the issue, let me begin with some basic information: This is in regards to my Samsung Galaxy S5 SM-G900T (T-mobile), running Lollipop 5.1.1, FOG6 build, DOB1 baseband, rooted, deodexed, but otherwise stock.
My problem: Today I flashed a rom via Mobile Odin Pro and soft-bricked my device. After a lot of hair pulling and screaming at my phone and computer, I finally got my phone up and running again. After trying many different solutions, I eventually tried re-flashing TWRP through Odin (recovery initially would not boot, hence the soft-brick), which succeeded, and then recovered my phone by restoring from a previous backup.
This got my phone up and running again, but once it boot, I had no service. I first checked my APN settings, but was presented with a message stating, "Unable to view the access point name settings. Access is restricted for the current user profile." I tried adding a new APN, but once I added it, it did not appear in the APN list, which continued to only display the above message. I then tried to "Search now" for Network Operators, but nothing was found. So next I checked my IMEI through "About Device", and discovered it was set to "Unknown". Checking the IMEI through the dialer (*#06#) lists the IMEI as "null / null".
I have searched high and low and tried everything I could find to fix this. I tried restoring my TWRP EFS backup to no effect. I also tried flashing the modem through Odin, as well as restoring my TWRP modem backup. I tried using an Xposed app to manually set the IMEI back to its original value (I happen to have my phone's original IMEI number written down from when I SIM unlocked my device), but while this updated the IMEI displayed in the dialer (through *#06#), it did not change the value in "About Device" and did not restore my service.
The last solution I tried (found here: http://www.technobezz.com/restore-galaxy-null-imei-and-fix-not-registered-on-network/) involves me using the dialer to enter Service Mode to make some changes; however, while dialing *#197328640# did open the Service Mode menu, the menu was totally blank.
Please help! Given the current state of my phone, I cannot make or receive calls or texts or do anything else requiring a mobile connection. I have looked everywhere and I don't know what else to try :crying: :crying:
Assistance in this matter would be greatly appreciated, as until I am able to fix this, I don't have a functional phone
Any suggestions?
I bought a new Lenovo A806 (original version android 4.4.2 - build VIBEUI_1432_ST_A806).
There were lots of Chinese writings imbedded in the rom and apps so I rooted the phone and tried to disable some apps and stupidly removed the stock phone dialer and contacts. Then whatever replacement app I tried from the Google play store did not work.
The replacement dialer gives me the message:- “You have removed/disabled Stock phone application, its required to properly functionality.” (pardon the Chinese English)
The phone cannot read the sim card and the IMEI number has disappeared. Following forum advice, I installed “mobileuncle” but cannot insert the IMEI number manually. When I go to Engineer mode, CDS information and try to go into Radio information, I get the message - “Unfortunately, Common Data Service has stopped.” So I cannot even go into Radio information.
I researched on the internet and tried to change the Rom. I installed the required version of TWRP recovery and after trying a few Roms, I managed to get Version VIBEUI_V2.0_1508_7.85.1_ST_A806 installed.
This version behaves better but still no IMEI number. Instead I get a different message – IMEI invalid.
When I try to call, I get this message: - “To place a call, first turn off Airplane mode”
But Airplane mode is off. But at least the dialer seems to be working and I am able to add contacts.
And I can get to radio information from mobileuncle with this version but when I type the IMEI number after the ST.., I get the message: “This command is not allowed in userbuild”
Even with a space between the ST and +, it still does not work and I get a different message, “at command is failed to send” I even rebooted after inserting the IMEI number and still no joy.
However, the wifi seems to be working on both above version and this.
I have a backup of the original corrupted rom so if anyone has a solution for either one, please help.
I installed the rom’s through TWRP recovery which is on my phone. I press volume and on/off buttons to enter into this.
I tried to install a flash tool and all the required drivers on my computer, I am using windows 10. I cannot seem to get the flash working.
Fixed
I managed to get the "SP Flash tool" working on my Windows 10 computer and that worked. Everything fixed. Thanks.
Hello,
I have received this old S2-i9100P from a friend as a temporary replacement, and it is simlocked with SFR, which is a French provider. I have tried to desimlock it with an app, the app said "done", but really nothing was done. To the contrary, now I can't even enter the pin code of my sim card(Belgian provider), as it is always saying "sim pin operation failed". I still have access to my IMEi, which starts with "35848...". I have read here and there that when this happens, you have to replace some files in the efs folder, namely "nv_data.bin" and "nv_data.bin.md5" with ".nv_data.bak" and ".nv_data.bak.md5". Is it the right way to do it ? Is that all I have to do ? Do I need to backup anything else, like for example everything that is present in the root ?
Also, in the mean time, I have installed LineageOS 14.1, which works well, is it ok or should I flash the phone with a stock rom ?
Thanks !
