Backup Imei Mediatek

[Karlotta Neifert]

NOTEThis method assumes your Serial Number is also invalid or null. However, if you have a valid Serial Number and only need to restore IMEI, you can still use this guide. Just choose method B below and do the IMEI Download option.

Thank you for the suggestion, Robert.

A similar method was linked to at the beginning of the tutorial. For phones that allow entering engineer mode in this manner, your method can certainly be used. Thanks.

Thanks for your Reply and Sorry for taking your time Long! Actually nothing happens when i dail *#66# I have Honor 3C H30-U10, I flashed Chinese Kitkat Rom Few weeks ago version 4.7.16, after OTA Updates the Phone become dead it was just vibrating with Off Screen, however with a lot of time efforts i managed to get it back, but I was not aware that IMEI is Gone :(, i inserted the sim and SIM is detected but No Signals, Ok In Short, I then started fixing IMEI,

The error you are getting is due to the wrong NVRAM database file. You need to find one for your baseband version: WR8.W12.46.p6. Official stock ROMs usually have it. If Huawei offers downloadable stock ROMs, there is a great chance they provide the database file.

hi, if you are able to fix your IMEI numbers via Mobileuncle Tools, then do it that way (no need to mess with drivers).

There was a similar issue discussed on the forum, where the SIM cards were responding erratically. Try to check the pin contacts in the sim tray. See if they are positioned fine.

Since you have two of the S720, you can also make an NVRAM backup of the other and restore it to the first one. But you will have to root the phone in order to make an NVRAM backup. See this guide -Tutorial-Backup-your-NVRAM

Lastly, if you wish to try using Maui Meta, here is a copy of the BPLGu file that comes with TCL S720 stock ROM Jelly Bean. _hDVlBfc2dOQXMySmc/view?usp=sharing

But like I mentioned, if restoring IMEI numbers through Mobileuncle Tools or MTK Droid Tools works, then you can just use those methods.

Nicki, Your reply got a little bit late. oops.

yESTERDAY AFTER posting comment here. i used maui meta with the modem database file placed in sp flash tools flashable rom, and it went well. I losted one of my 2 imei numbers. so i used one on the back of phone and i used one from a discharged & not working old sony ericson phone.[Yes, it was having different for both sim slots]

I used mobile uncle and it went well, but as i said when i reflashed my phone to official rom, i lost them again, i guess that is because mobile uncle was just changing soft IMEI numbers. plus I was getting that disconnection.

tell me were all the steps correct?

Hello,

I just restored my missing imei number and my serial number is 0123456789ABDCEF. Does this mean that is the serial number the phone is using or is my real serial hidden someplace? This has been making me nuts for months.

Hello friends, i formatted my eMMC with sp flash tool, I lost the Imei number and signal after flashing the rom again. Imei, bt, wifi mac etc, were flash succesfully by sn write tool. But signal callibration was already lost, but i flashed that too. Bit it only gave me WDCDMA(3g) signals and not GSM(2g) signals.

PLEASE HELP

I got this error : NVRAM database file is inconsistent with target load.

therefore, I cannot Download to flash the imei numbers.
