Changing/Spoofing MAC Address[Solved]

Hi guys.....here is the way that helped me change my mac address permanently(surviving reboots).I have tried this in Redmi 3s Prime and can confirm that this works.
Note: take a backup of the *.qcn file of your own phone using the qpst tool and have it safe , so that you can restore it if anything goes wrong messing your imei or mac or when you want your original mac address back.
Required Tools can be downloaded either in the miui forum thread(Thanks to the thread creator) mentioned in step 1 or through this GDrive link : https://drive.google.com/folderview...ldGtWNHc&resourcekey=0-tvs1q3f3cTxYIltpcgD4VQ
So lets get started.
1 ) head over to this thread [ http://en.miui.com/thread-348525-1-1.html ]
and follow all the preparation steps(steps 1-8) including installation of software and configuring the phone in diag mode.
2 )Open qpst tool and StartClient-->SoftwareDownload.
then go to Backup and take a backup
3)Open a copy of the resulting file (*.qcn) in any hex editor and search your phone's mac address as hex.
Eg. : if your mac address is 01:02:03:04:05:06 search it as 010203040506
[IMAGE http://i65.tinypic.com/2006xxz.png ]
4)You will get some search results. Now edit every search result with your desired MAC address.
5)And finally restore this edited *.qcn file and reboot your phone once complete.
And that's it. You have successfully spoofed your MAC Address. :good:

Much appreciation for this guide.
It works for me although in my case for step no.3 the diff was when searching for the stock MAC address I had to set txt string not hex. Only then the hex editor could find the proper 4 placements from the backup.
Just in case if anyone else ran into the same search issue with the hex editor.

Did you disable driver signature enforcement in windows before installing all the drivers??
If not Google how to disable and later install the drivers again and try. I had the same kind of problem. And this worked.
I just reboot without driver signature check & did process again : no changes.. :/

Kinda long & risky but I confirm this method works on Redmi Note 4X SD. Even so it's not that practical, means that you can't change MAC Address on fly, every time you have to find a PC to change the MAC address.
Where is the address in QCN that store Wifi-Mac-Address data?
my mac address is 02:00:00:00:00:00 i dont know my old mac address so how can i find it in this qcn file?

How to spoof WiFi mac address for Snapdragon625 (Redmi 5Plus/Redmi Note 5 [indian])? I use this method but I can not find wifi mac address inside qcn file. I try to search hex number but no digit same like my device mac address.
i highly recommend to backup as xml format (.xqcn) with this format you can open .xqcn file using notepad++ to find your mac just search using your original mac e.g. 02:00:00:00:00:00 then just search using 02 00 00 separate by space or full digit without ":", for SD625 first test using this app if you facing force reboot then use guide from this thread, highly recommend to backup original .qcn/.xqcn if you want use this guide.

well... if you backup as .xqcn notepad++ is enough no need using hxd, hex edit or etc because it is not binary format, to see your original mac it's appears on setting>about phone>status> wifi mac bla bla ..., if the mac change when you change rom it's about rom/kernel related to lineage or that custom rom you used and if you flash stock rom i'm sure it'll revert to original vendor mac, try to search using three group of your original mac on .xqcn, and if you still can't find it maybe it chipset related, but i think SD625 still family of SD425/430/435 series

Is it possible to install GApps while cooking the rom?

Hello friends,
I'm finishing cooking my first rom, the rom is for an Android TV Box, my only problem so far is that I can not make Google Play Store work correctly ...
The rom is not with root access, what I did is the following:
1). Unpack system.img
2). Copy the files of "open_gapps-arm-4.4-pico-20180307" to the corresponding addresses
3). Repack system.img
4). Flashing my TV Box
With all these steps I managed to install Google Play Store without getting errors indicating that the application was stopped ... The problem now is that every time I try to install an application it throws an "error code -2", indicating that it can not be install the application ... What could be the problem?
My TV Box has an Android Kitkat 4.4.2 and its chip is a Mediatek.
I hope someone can guide me!
Thank you!
This might point you in the right direction.

Thanks friend! I'm going to analyze it and I'm going to post results!

Unbricking Amazfit Smartwatch 2 for Dummies

Before I bricked my Smartwatch 2, I haven't got the faintest idea about adb or flashing Android ROMS, in other words, I was a total dummy. But thanks to my careless mistake, I have now discovered a whole new world I must admit that the many attempts were quite frustrating and my guess is some of you reading this can totally relate to that. The solutions to the problem are actually all out there but they are scattered over different places. So to save you the pain and agony I went through, I have decided to put them all in one place here in a one-stop, step-by-step guide. I do not claim any credit for coming up with any of the solutions.......I'm just collating them. Real thanks should go to those who wrote the codes and instructions, and made the youtube videos that you are about to see below.
Before we start, two important points to note:
1. Follow the instructions very, very closely! It was carelessness that got us here in the first place. Most of us missed one very critical step that caused the fatal error - we didn't unlock the bootloader. YOU NEED TO UNLOCK THE BOOTLOADER! No two ways about it!
2. If you are new to adb, spaces are very important. Look closely and make sure you don't miss any spaces
Let's begin.
1. Follow the instructions in the post below from "Things you need" until Step #9. Do not go beyond that!
http://en.miui.com/thread-440615-1-1.html
2. Connect your Smartwatch to the pc via USB now if you haven't done so.
3. Next, follow the instructions in the post below. It is in Italian but if you don't know Italian like me, right click in the page and select "Translate to English". Clock in the translation refers to watch.
http://nicolasagliano.com/lo-sblocco-del-bootloader-e-arrivato/
4. Your watch should display a triangle with ! in the middle when its in recovery mode (see attached photo)
5. Next, go to the link below and follow the instructions in "Installation on Custom ROM" until Step#5 only
https://forum.xda-developers.com/smartwatch/amazfit/rom-stratos-amazfit-sport-watch-2-t3746334
6. Once you have installed the new ROM, your watch will reboot and a QR code will appear (see attached photo). At this point, you need to download and install Amazfit Watch app on your mobile phone. Turn on Bluetooth on your phone and pair it with the watch. Select your watch model on the app and scan the QR code. If the app doesn't recognize the QR code, you need to scan the code with your usual QR code scanner app. It will provide you with a link which you should go into and download an apk which will update your Amazfit Watch app. Once the app is updated, launch it and scan the QR code on the watch again. It should work this time.
7. Your watch is now in Italian mode. To switch to English version, watch the last part of the below youtube video:
https://www.youtube.com/watch?v=pwdAjhamhVk
8. Enjoy your newly unbricked watch!

Samsung GS3 I9300 IMEI corrupted/lost/null restoration.

Ok. So here's the deal:
My SGS3 I9300 exynos phone did the famous IMEI 0049 and SN null trick.
I cannot say what precipitated it but is simply stopped registering on the network, so no calling or data. All other functions operational.
After much searching and reading, I settled on flashing the stock 4.3 back. This succeeded only in doing absolutely nothing to alleviate this issue. I wiped the entire phone. Maybe I missed a critical section wipe, but since the stock ROM overwrites all? the CSC/BL/MODEM functions I thought it would set the default for EFS (which I believe is where these critical data live). I'm not a programmer so I cannot say diddly about the architecture and interrelationship of OS files, but I am technical and I know how SW and HW does what it does.
This phone is my own and I have all the rights to it.
I had loaded RRemix ROM a loong while ago and it was functioning fine. Probably a corruption of the EFS due to battery contact being loose. This is in my mind the most likely cause as the system may be accessing the EFS files, say making a call, or accessing data, and the power drops out and voila! Corruption. But again this is theoretical.
Needless to say I tried the usual hocus-pocus out there with no avail.
Getting to understand the system better it seems obvious that these critical identification numbers are hard-coded into the chips on the phone. Which explains the ability to 'fix' them with JTAG and other cable/box solutions and SW. However, I cannot see how the SW loses the ability to read the IMEI/SN that is hard-coded (fused?) into the main-board.
All my research pointed to the EFS files having something to do with this.
Way back when I loaded the custom ROM I did not come across the 'backup your EFS' as a necessary step, so I had nothing to go back on.
And loading the stock 4.3 ROM back on and not having that fix the issue, led me to believe something else was up.
Somewhere in the guts of this phone something is screwing up the layer between reading the registers where the numbers sit and the software layer that reports the numbers.
So, much searching led to the nv_data.bin file being a key component in all this fiasco.
Now, before I say any more, I believe that describing the next steps could be a big no-no here.
Now, understand, all I want to do is get MY personal device working again. I have the SN and IMEI numbers on the physical device.
Sure, I could have stolen it and am attempting to change these to avoid prosecution. Anyone can say anything online.
Therefore, before I can proceed, I need advice from moderators and VPP to either say 'Yes you may post this info' or 'No. Go away'.
Am I allowed to do the following:
1) Describe how I restored my IMEI (Not changed, overwritten, or subverted to my limited knowledge)
2) In the case of 1 not allowed, post the link to where I found the info to achieve this.
3) Submit the 'fix' to a moderator or developer to check whether this is indeed and restoration or a change.
If it's a restoration of existing functionality, I cannot see how this could be a problem. If its changing something, then it's a whole other sack of ferrets.
My reasons for posting are that xdadevelopers has given me years of joy with my SG devices. (Yes, I have the whole range exclusively) Many ROMS, customs, fixes, hints and saves deserves something back, and the difficulty in achieving this particular fix, warrants it.
But I don't want to break any rules, this being my first post.
So, please let me know what I can do to help others stuck in this position...
You can find it if you have the correct search parameters. Perhaps I can say that instead?
Thanks.
And thanks to all who have helped over the years.
T
[Edit] Just to clarify, the solution requires no special HW or 'boxes'. You do need root, however, and a hex editor. I had a reply explaining the use of Octoplus, which requires credits and registration. You will need none of those.
I can't speak English but I will try.
1- flash stock firmware.
2- root your device s3 .
3-in the web download " octuplus crack box"
4-in youtube see how install " octuplus crack"
5- before install stop your antivirus PC
6- open octuplus and connecte your phone with PC
7- chose your device i9300 .
8 click repair imie
9 click read info and do what OCTU said to do.
10- click repair or write the true imie in your device ( remove battery to see)and click repair.
11- restart phone .
12- see: call work fine
13- in phone go to mobile network\ access point names\ apn's
14- write your network.

How to restore corrupted or null 0049 IMEI on SGS3.
Right.
Thanks to the moderators for agreeing to let me share the solution. :good:
Thanks to the reddit poster who found this solution. I don't know how the hell you figured this out, but big-ups to you. For privacy I will not mention names or addresses.
You do need a rooted phone and I cannot assist anyone without root as I have not tried it.
Whether this only works to restore a corrupt IMEI or change it, I cannot say, but it managed to restore my existing one.
Preparation: Get your IMEI number from under your battery compartment. Say your IMEI no. is: 123456789101213, write/type it in the following fashion: 1 23 45 67 89 10 12 13
Now some funky transposition: Excluding the first number, transpose the subsequent pairs of numbers so that you have: 1 32 54 76 98 01 21 31. Can you see it? Swap 23 to get 32. 45 to get 54 and so on.
Now add 08 to the beginning and add A after the 1 so that the completed number is: 08 1A 32 54 76 98 01 21 31
Now you will need:
Rooted Galaxy S3 (This may work for all android devices that have an EFS folder. If anyone can confirm that would help others.)
Hex editor (PC based or Android app) - PC is faster and easier. I used hex workshop trial version but I'm sure any editor will do. I used the default install configuration.
USB Data cable (if using PC editor mentioned above)
You should probably back up the EFS folder entirely, just to be sure.
Using your favorite root explorer browse to root/EFS folder and copy the nv_data.bin file to an accessible area in sdcard. I use a /sdcard/Downloads folder.
Either open the file with your hex editor app or transfer the file to PC where you can open it with your hex editor program.
Open the file and jump to address 00550.
Now, get your modified IMEI number from the prep steps above and enter the values in the ASCII TEXT window to the right, NOT the HEX values window to the left. This may be different for other editors but hex workshop works like this.
Double check your address and entered data. When satisfied, save the file and transfer back to the phone if copied to PC.
Now, place the phone in Airplane mode, turning off the cell radios.
Go to the EFS folder and rename the original nv_data.bin file to something else. I used nv_databak.bin.
Copy the modified nv-data file into the EFS folder.
Turn off Airplane mode and do a full reboot.
Your IMEI number should be restored and cellular functions should work.
My previously garbled serial number was also restored.
I hope this works for you. I have no knowledge of any other method as I did not delve further into trying other numbers or such. I can't assist any more other than further clarifying the steps above if you don't understand something.
If anyone can decipher what is going on here, I would love to hear about it. I suspect something between the HW and SW layers is getting garbled or corrupted and this kick starts the process to get the correct data again.
Maybe.
May also contain nuts.
Hastalavista.

THANKS FOR POSTING THIS HERE!
I have this Samsung Galaxy S3 that I bricked 4 years ago and never wanted to sell it or even try to give it away. I searched for months for a frekin solution to this problem. Yesterday night i decided i wanted to try and install custom roms on it and so i wanted to give another shot at this stupid issue i had with the lost IMEI before doing so...and BAM! Today it's fixed!
I'm so thankfull I wanted to post here so that you know that you helped at least one person with this
Thanks a bunch!
@TrinityTrip54
Hi,
can you confirm that this is a permantent solution and remains when flashing new (custom) ROMs? Or is it just for the current installed ROM?
And I am having an issue with "jump to address 00550" in Hex Workshop. There is no address like this, just 540 and the next one is already 558. When inserting 00550 in the goto search field of Hex Workshop it jumps to 210. Any idea?
thanks anyway.

Hi,
I managed to get the Android 11 update with a bit of stuffing around and thought I would share for everyone else, I did this on a unlocked Australian variant bought from Optus, you're mileage may vary.
This will activate dual sim mode on the phone with a single IMEI, I left my location set to Europe so it is upto you if you follow the last step to remove Dual Sim Mode.
You will need to backup anything you don't wish to lose as a full factory reset is required.
I did some digging and this will work with the same rom on A52, A72 and A92.
Could I get a moderator to cross post this to the other device forums please?
