My ip address and wifi mac address is constantly changing with every reboot. Help. - Karbonn Sparkle V

Hey guys,
So, I recently got my phone flashed due to some errors and now there's another problem with my mac id and ip id. It changes after every phone reboot or wifi on/off. I even tried resetting but it was all in vain. Consequently, I'm having a tough time connecting to my ISP, since it's bound to a specific mac address.
Any help would be appreciated.
Thanks.

Try to downgrade your device software

I am pretty sure that your NVRAM partition is corrupted (this is where the MAC adress is stored). I haven't found yet a solution to fix this for our device...

Refer to this threadhttp://forum.xda-developers.com/sparkle-v/help/karbonn-sparkle-nvram-wi-fi-mac-imei-t3362687as the NVRAM is erased because you upgraded the firmware with the Format All + Download option that erased all of your mobile data.

[Q] IP Address unavailable

Hi guys i have a problem with my IP address when i go to settings>about phone>status my IP address says unavailable ive tried switching my phone off but nothing works i think this is affecting my wifi as well because it also says settings not responding when i switch it on and when i use other applications to switch it on they fail when they are collectiing my wifi address someone please help me i miss WiFi:crying::crying:
Since you didn't post the device information (ie phone model) nor the router you use, it doesn't allow us forums users to give you the best options to troubleshoot the problem your having
Some generic options to try
1) try powercycling the router (linksys have a tendency of dropping Wifi connections)
2) check to see if the wifi toggle is on (the settings menu)
I have the same problem as well:
my phone specs:
Software version: L720VPUEMK2
Device model: SPH-L720
Android version: 4.4.2
A couple of days ago i had installed the newest update for the s4 and when it had finished installing both the bluetooth address and the ip address said unavailable and i am now unable to connect to any internet

It looks like your efs has been missing.If you have a backup.Restore it.
Flash the modem separately may help too.

if you r having problem with efs file then try this.
1> you need to root your phone first. check out forums there are tons of tut's available.
2> goto this post and download efs professional zip.(you have to extract it)
3> enable usb debugging in developers mode and make sure you have all the usb/adb drivers installed on your phone.(install universal adb drivers that will work fine)
4> open efs professional.exe and connect your device.
5> now go to backups tab and select your device under device filter tab and then click backup. wait for backup to be complete.
6> now go to restore tab and under backup archives select one of the .tar.gz file I prefer (device)(although it doesn't matter) and hit resotre.
7> your device will reboot and you are done.
if you still have the problem
download root explorer and goto efs folder in root directory. then find this file - 'nv_data.bin.md5' and delete it and restart the phone.
if this helped then hit the thanks.

[MTK][TOOL][APP] MTK 0x10 NVRAM FIX

Hello guys,
After updating my app MTKTransfROM, I'm here to introduce you my new simple little app that fix the most famous MTK WiFi Bug for who change Custom ROM everyday the NVRAM WARNING: Err = 0x10.
It is a label that appear on your WiFi Networks indicating you a MAC NVRAM error. It's there due to a /data reset that hasn't been correctly restored by your new ROM.
As I'm a fanatic of Custom ROM, It is pretty annoying to fix it every time by entering Engineer Mode, Take WiFi MAC, put it in a special menu, bla bla bla...
So I created an app which do it in milliseconds. It's really little app and doesn't require any permission, IT ONLY REQUIRE ROOT ACCESS to write to NVRam Folder.
Here's the link: Play Store
It's AD FREE, but if you want to support my work and buy me a beer or a pizza ( I'm Italian ) here's the donation link: DONATION
Thanks for Reading
can you send it to me?i cannot download form googleplay,because i come from china
my email is [email protected],thanks
Thanks man, that helps!
I lost my 5ghz band after using this app
Please update this app to support 5ghz band also
I had to restore the NVDATA to make it work again
Please I am having NVRAM WARNING ERR =0X02 after using this app. How do I fix that please cos it showing up on my wifi setting
nvram warning err 0x02
@wesleyel did you already find a solution?
I'm facing this error on my Xperia XA Ultra (F3211) after I tried to set a new wifi mac address by editing the WIFI file in the /data/nvram directory because I first had nvram warning err 0x10 any changing mac addresses after every reboot.
The wifi mac address only seems to changes if the mac address starts with 00.
Btw: is there any possibility to read my original wifi mac address? All tested tools only show me 20:00:00:00:00:00 :/
Best regards

Yes I was able to find a solution after a loads of research.
I used an app called chamelemac. You can download it for free on playstore.
Hope it helps you too.
Also am not sure if you can retrieve your old wifi mac except you have an nvram backup or maybe it's written on your phone pack which am not too sure.
Thanks for your reply @wesleyel
Unfortunately the app does not support my device so I tried another one but it did not fix this issue.. So I'll go on searching the internet and trying to find another solution.
Best regards
Hi! I'm typing from a chuwi hi9, equipperd with a MTK8173. I Also had this nvram warig ecc... But, after i've run the app andò reboot the tablet, unfortunately, it don't detective anymore my 5ghz WiFi network, only the 2,4.
How is this possibile?

Where is the device MAC address stored?

I think I've accidently wiped a partition - maybe nvram - possibly through an overzealous use of SP Flash or mtkclient whilst trying to install a GSI ROM. However it happened, I now have no device MAC and a generic serial number. Can I manually recreate them? Either with a 'setprop' through adb or hex edit on a dumped/reloaded partition? I've dumped the nvram partition and it's all zeros, so I'm guessing it's the one I need to rebuild/recreate.
The device is a Lenovo M7 tablet, and I've restored it to stock with Lenovo's rescue tool - that didn't restore the device MAC, and I get that. It's working fine but it has a new device MAC address on every reboot. I think what is happening is the system software is giving out a random MAC because there is no device one. The serial number is no big deal, but I'd like a fixed MAC if possible.
Edit: Android 11 Go
Ok, bumping with a related question.
In which partition/image is the device MAC stored?
I'm only guessing it was in nvram.
(Btw, I tried a factory reset too but that didn't restore the device MAC either)

NV partition gone

Hello , yes i erased the nv partition by a mistake , but, i still have the box with 2 dual sim IMEI and ither 2 codes on it, someone told me i can repair them but dont know how exactly. Should i use Maui meta or Sn writer tool? Do i need nv backup of another redmi 9 to do this? I remember many years ago i did it but i really cant remember how
The /NV partition not only holds the IMEI but other important data, too, such as SN, Baseband, product code, BT/WiFi mac address, RIL calibration files, DRM info and some other data like language, timezone set by your provider.

Ty for helping, can i ask you wich one of those Is foor Google authentication? I have SN , imeis and others, but seems like i cant use sn writer to writer those, my NV partiton Is erased, i tried to flash nvram and nvdata with no luck, tried with SPFT gives errors, tried via fastboot but there Is a protection and doesnt work.
Now i flashed twrp and installed magisk, i wonder how i can remove those protection that wont allow me flash those partitions.
Aniway only thing not working Is the signal ( but detects Sims) , and Google , seems like invalid Mac address too
IDK
what exactly does not work with SN Write Tool?
"It allows users to flash various options apart from flashing the IMEI only. It supports Barcode, BT Address, Wifi Address, Wifi EPPCopy, Mac Address, DRMkey MCID."
the funny thing is you did the same stupid mistake like years ago..
I get errore messages, seems like my PC fails to connect, i do t know if needs CDC drivers, but i cant Install them because my PC wont Install unsigned drivers even if i try to disable that with CMD, changing boot options, or tools to allow that, maybe because its a light, modded version of windows and Is missing many services and sruff, aniway i fixed It by using Maui Meta winth a ENG rom, second IMEI was ok but had still the dm Verity corrupted, then i installed Magisk and disabled Verity check teough Fastboot when flashing Vbmeta.
I still have invalid Mac no serials etc, but everything Is working indont really Need to write those, i can Remember using SN write tools before with another windows
, Will try when i change OS, thank you

I did not, i can ONLY use Maui Meta v 10, i dont understand HOW and if i can use the NVRAM editor to write that. I researched a bit but found nothing about that
I think you need to select proper baseband from database, then just enable one more checkbox for repair Mac address, thats it.
Or do you mean SN Write Tool isn't working at all? The flashing procedure is same as for SP Flash Tool, you need VCOM preloader drivers installed and device powered off.
