[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.

[Tutorial] How to fix the random MAC address/NVRAM error on MTK-based phones

UPDATE: Here's a tutorial vid on how I did the MAC address procedure with my phone:
https://www.youtube.com/watch?v=SdAtvju0HZ0
OK, so I scratched my head in wonder as to how can I get rid of the annoying NVRAM error. The hex editing trick didn't seem to cut it for me, not to mention that I'm not up to rooting the device yet.
Tools needed:
SN Station: http://d-h.st/X8J
CDC Drivers: http://www.mediafire.com/download/yxsq7qql58o3hre/Android_Gadget_CDC_driver.rar
Stock firmware for your device, in my case, a Lenovo A369i
A phone, a USB cable, and some patience.
Now, let's get this show on the road, shall we? Install the SN Station tool, and fire it up. Try adding SN_STATION.exe to your DEP whitelist if you're getting a 0xc0005 error.
On the Function Select section, choose Write WIFI MAC Address and Smartphone. Also, make sure that Meta Mode is switched on. As for the connection setting, I used USB VCOM. That's where you'll need the CDC drivers for.
For the NVRAM database files, I used the following, which can be found in your device's firmware packages. This depends on the phone though:
Code:
Modem:
DbgInfo_WR8.W1315.MD.WG.MP_LCSH72_WE_JB3_HSPA_MOLY_WR8_W1315_MD_WG_MP_V1_P14_2013_10_12_14_06_1_wg_n
AP database:
APDB_MT6572_S01_MAIN2.1_W10.24
Now click start. Turn off your phone first, and then plug it in to the USB port - it'll then switch to meta mode. Upon doing this for the first time you'll end up with an exclamation point icon in Device Manager, CDC or something like that. Right-click on it, click on Update Driver Software, and look for Android_Gadget_CDC_driver.inf. A warning may show up, but click on install anyway (after all, nobody cares). If done properly the CDC driver would be loaded.
A dialogue box will then appear, to which you need to enter your MAC address. If you're having a random MAC like with my phone you might want to generate a fixed one. Click on enter, and if done correctly, the write result indicator should turn green. Unplug your phone, and then power it on. Turn on your Wifi, and go to your device's status page. You should see your new WLAN MAC address. On the WLAN settings page you might still run into the NVRAM ERROR entry. This is normal, and you can now get rid of it by long-pressing on the said AP and tapping on Forget network.
And there you have it - problem solved.
Feel free to post any corrections or amendments, I know this isn't the only tutorial that sheds light into this matter, but I thought well maybe I should share my experience to you guys.
And by the way, I am in no way responsible in case your phone fudges up or anything.

Did you write the MAC manually, or the program generates a random new one?

How to change mac in this device

Yeah, i haven't found any way to change anything in nvram so far.

This doesn't work. Any of changers doesnt work. I even tried changing it with terminal. It seems like nvram is somehow hardcoded in the device

i could not find any solution either. Indeed i have lost my imei numbers during rooting my device. now i can not use my device. Can anyone provide his backup files NVRAM/NVDATA etc for me. Thanks in advance

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.
