After That i selected Format and Download ( normally we just download but i selected format and download ) and found flashed the rom . Now i noticed the serial number of the device was turned to 00000000 and imei number to invalid . So now i fixed the invalid IMEI number problem .

CHECK THIS VIDEO BEFORE MOVING FURTHER -
To check Serial Number just connect your phone to PC ( usb debugging ) and type adb devices ( correct adb files needed )
You can also use Uncle mobile tool -> Device Information to check the serial number
Using Different serial code for infinite warranty is not a good idea as there is serial code printed behind the phone. :p and its illeagal .

Note : This post is for educational purpose only . Here i will be teaching you how to regain serial number to the one which is on your device box ( u should not change serial number to something else ) Customer service refuse to help me with a wrong serial code so i found out how to regain old serial number .

ROOT + NON ROOT METHOD :Step 1. Download and Extract the package given below .
Step 2. Run IMEI and SN writer .exe file .
Step 3. Download the DB as well as GLU files for your mobile.
Step 4. In IMEI and SN writer Select USB and then smart phone
Step 5. Click on 'Select DB' and attach GLU file over there , Later on attach DB file ( once you double click on GLU file the popup wont go , U again need to select the DB file )
Step 6. Now Select Serial Number , IMEI , Bluetooth , Wifi mac adress in write item and write what numbers and values you want.
Step 7. Click on start and turn your phone off.

Hi, I did like you (format&download) with my tablet Lenovo Tab2 A7-10F and lost Serial Number, as well as the Wifi mac address (it changed every reboot). It's the mediatek MT8127. Where can I find APDB and BPLGUI also other stuffs (meta modem?) to write back the SN and PN?. If it's in the stock rom, which file should I take? Many thanks for your help, I'm newbie :(

Doubt

Hello. I am beginner and I need a help from you. I am trying to follow this procedure, but I'm having trouble with the GLU and DB files. I read that the GLU file is within the Imei fix package, but how do I know which file is compatible with Galaxty S3? The DB is also in this file? Thanks.

can I write old logical board info on a new one(S/N,IMEI...)

Hello all,

I would like to buy a new logical board for my N910c but I have a few question before, if any of u know to answer me.
I would buy it as new OEM because old one isn't fully functionally (missing blitz camera + sensor, lose wifi signal or is low, 4G)
1. when logical board come to me will be without Sistem, IMEI,S/N... ?
2. can I write old logical board info on this one. S/N, IMEI...
2.1 This can be done more easy and right in a Samsung authorized service and
phone will have no problem in future?
3. If the answer for this is yes come another question, if my KNOX will be untouched 0.
3.1. new system update will come as normally?

Reason I want to do by myself is price. I found is more cheap to buy same logical board. Samsung authorized service give me logical board with almost +10%.
I need this info on new one to make my identification with some device from work.

Thank you for your time.

Hello , i have found a solution to fix imei issue which is much simpler than sn writer tool. This method works for rooted devices.
All you need is an android device which is rooted(use kingroot as it works flawlessly on android 4.2.2 and above)
after your device is rooted download Chamelopon apk from playstore or from xda itself.
Open the app and click on insert imei, write your imei and reboot your device....and there you have your IMEI fixed. Ive tried many tools but this works flawlessly and saves a lot of time.
Hope you find this helpful.....CHEERS

Problem.

Hay, there, Thanks for the post, I was glade that in 2015 someone there also thinks for old guys too, because i have seen most of the post for MTK are before 2015 and inactive,
So my question regarding this is that, is this fix is the permanent solution for NVRAM ERROR (Which causes invalid IMEI, Wifi mac address changing, S No and i don't know what it does to the Bluetooth) AND The GLU file you gave does not have the MT6572 does it support my wiko Lenny MTK6572

AND BTW where can i get DB & GLU for my Wiko Lenny Mediatek MT6572, Dual-core 1.3 GHz Cortex-A7 (I really don't have them and couldn't find them from uncle google yet, meanwhile i have downloaded an update file from wikomobile.com/UK and have an SPFlashtool flashable ROM but it also doesn't have the NVRAM as far as I can see. You guys are devs you may also now some ways to extract NVRAM for system.ext4 or somewhere)

And Finally whether i can copy paste my current NVRAM folder (while i know the error is there because i have made this backup after i got the NVRAM WARNING Error 0x10)
Please HELP because i think my questions are quit relevant to the job and the fix you kindly provided to the sanking guys.

Thanks again

If you have any problem you can contact me
