[Q] how to change iSerial

[Q] how to change iSerial - Micromax A116

Hi All,
unfortunately i selected format option while flashing stock rom via SP Tools & i lost my imei, serial#, mac address etc. However i sucessfully managed to correct the same via MauiMETA tool. Now thing is that when i connect my device in meta mode & check my serial number in MauiMETA it displays right but when i check it via Settings > About Phone > Status then it displays 0123456789ABCDEF, which is not matching with my device's. serrial#. I googled & find somewhere on stack exchange that this can be corrected through /sys/class/android_usb/android0/iSerial but when i try to open this file in edit mode it does not display anything & i can not write the file. I read somewhere that this can be done via custom init.d script but i don't know how ? can some one please help me out ?????
Thanks,

[Q] need help

asslam o alaikum, and hello brothers and sisters here, i am a new user here. i need help. i have a lenovo A3000-H ideatab. i buy it from china. i do the firmware upgrade from http://forum.xda-developers.com/showthread.php?t=2441135. but the bad thing that happened is, i format and then i download. the problem is that now invalid IMEI..that i fixed it by Engineering coding mode...
'"code in Engineering mode:-"'
Just enter this code in dialler:- *#7465625# or * # * # 3646633 # * # *
Now Tap on Call pad or connectivity option or you have to slide the screen.
Just Look for CDS information (Common data service information) option.
You will see Radio information there and after tapping on it.
If you have dual SIM ANDROID then you will see TWO option select any one on which you want to write IMEI with.
Now you will have to put your IMEI no in this manner :- “AT +EGMR=1,7,"IMEI_1” and “AT +EGMR=1,10,"IMEI_2” (replace IMEI_1 and IMEI_2 with your IMEI no) and tap on send command button.
for Example :- “AT =EGMR=1,7”9100XXXXXXXXXXXX”"''
( also it will be helpfull for others) please do not misuse it. its just help to solve your problem
the other problem that i fixed it is nvram error= xo1 for wifi mac adress that was formated by me... i just took a data\
nvram\APCFG\APRDEB\wifi from it i copied wifi name document from my friend tab that is same to me and paste it into my tab data\nvram\APCFG\APRDEB\wifi. my tab wifi doc replaced . the NVRAM ERROR=XO1 from wifi gone...
the thing that i need is that when i restore to default after some days to check there were no IMEI . it says invalid IMEI and also the same NVRAMERROR. that i fixed it again by the above method that i explained. then i do firmware upgrade but this time i did not select the format option, i just download.but after finishing firmware upgrade, when i turn on my tab it says INVALID IMEI AND SAME WIFI problem NVRAM ERROR. BUT I WANT THAT is there any method from which if i ever do firmware upgrade or restore default it should be fixed and it will not say INALID IMEI AND NVRAM ERROR. I JUST HATE IT. PLEASE IF ANY ONE HAVE ANY IDEA IT WILL BE A LOT HELP ...

[Q]need help INVALID IMEI AND NVRAMERROR

Any way to change MAC and connect to Password Router?

Hi!
I tried several guides on the internet to change my MAC address, at first, using one of the "MAC spoofer" Apps, but they all just change it "softly" so you can't connect to Password protected Routers (same happens if you use the busybox/terminal method), but my router is password protected and i need that protection. Next i've tried this guide:
"After your rooted head into terminal emulation type su and go into /data/misc/wifi
Look for a file called nvram.txt
Copy it to your sdcard and then to your cpu desktop open it with notepad and at the bottom of nvram.txt is the mac address
This i was able to verify and test on android Citrus Ciena
Edit that mac address and save it as nvram1.txt onto sdcard
Now go back to data wifi misc and copy nvram.txt to nvram.bak
Head into gui and then settings then wifi then turn on the wifi but don't connect to any wifi
turn off the wifi,switch back to terminal
Copy the nvram1.txt to data misc wifi
remove the original (make sure you got it backed up)
Rename nvram1.txt to nvram.txt
head back into gui and then settings then wifi
Now for me it immediately stated unable to turn on wifi
Ignore it and try to turn it on anyways
When it turns on your newly edited mac address will take effect
Connect to your AP
NOW B4 REBOOTING YOU MUST CHANGE NVRAM BACK TO THE ORIGINAL!"
but I haven't found the nvram.txt, so i searched and searched and found out the "s3 version" of it, is "/etc/wifi/nvram_net.txt" but in this file, my s3 shows me a completely different MAC, as my handy actually has. I tried the method with this file anyway, but it didn't work, i still had my old mac, but the MAC written in the file was not reset, so it seems like the system doesn't even care about the MAC-line in that file. So next I found the ".mac.info" file in "/efc/wifi/" and in this file, there is just my MAC written, which really is my actual MAC. So i tried the Method i've pasted above with that file, and it didn't work, the system did just overwrite that file and as i checked after turning my WLAN back on, there was again my old MAC in the file. Then i tried changing it and making it read-only through Root Explorer, but it didn't work either. This time the system afterwards still had the old MAC, but the file didn't change, so in .mac.info there was still my new MAC written, but the system still had the old one. After some time i checken the file once again, and then suddenly the old MAC was written in the file, and the system did automaticly gave writing-permission back. Now i'm just desperate, so if anyone can tell my any method to change the MAC, which works on galaxy s3, please tell me.

tools here

I would suggest to install Xposed and you can find IMEI changer in the download section. This will change only one IMEI number though. I mean IMEI1=IMEI2.
Another option is to use DFS tools.
And a 3rd option is to use Xiaomi (or similar for dual SIM) IMEI changer, you can use it to change both IMEI numbers.
All can be done provided that you have the box that the phone was packed in with the IMEI numbers on it.

Go to the section Guides where you have posted in a topic with "unlock bands..." There you have all what you need in the OP. Connect your phone in DFS tool, check the section where you have IMEI and update it.
Or use what I wrote with Xposed and IMEI changer.
PLEASE DO NOT CREATE ANY MORE THREADS!!!

sir i downloaded i triedwrite imei but its only sim 1 imei apearing
sim2 showing unknown

Search for "WriteDualIMEI(W+G_eMMC).exe" file. Once you found it, check instructions on google to change the IMEI. It is working for Xiaomi devices as far as I remember. I tried on LeMax2 and it worked. I said I'll do a guide but time did not allow and also I forgot later on. For sure you can find instructions on xda as well.
This is the only tool I found to change both IMEIs.
Good luck!

I'll write down the instructions for you.
1. Phone should be rooted, adb drivers installed
2. Connect the phone to PC and select MTP and USB debugging
3. Open command prompt from Start. In Run, type cmd.exe
4. Type in the command prompt the following: adb shell
5. Then it should show [email protected]_x2:
6. Then type: su
7. Grant access on the phone
8. Then it should show [email protected]_x2:/ #
9. Type: setprop sys.usb.config diag,adb
10. The phone will go to Diag mode, check in device manager if it's like this. It should show at section Ports: Qualcomm HS-USB Android DIAG 901D (COM6). "6" is an example.
11. Open the WriteDualIMEI app and you should see in COM: COM6. This means that device is connected and you can type in the IMEIs.
12. Press START and that's it.
