[Completed] [Q] Unable to read NV data on Galaxy S2 after rooting - XDA Assist

Hello All,
I am new to rooting phones and recently tried something on a galaxy S2. I had a korean version of S2 model SHW-250s which was locked. I lost my new phone so tried unlocking this myself...looked at some youtube videos some blogs and finally decided to use this method posted by someone:
1)Flash these two files using ODIN to convert the korean model into international version :
GTI9100_ext4.pit
9100XWLPW_I9100ODDLPC_I9100DDLPB_HOME.tar.md5 (stock ICS firmware for my country).
This successfully converted my phone to S2i9100.
2)Then to unlock I used a siyah kernel as posted by a developer :: Siyah-v3.2b8
This successfully installed SU and i checked using RootChecker apps that there is root access.
3)Then to unlock my phone i used GalaxSimUnlock app (did rooting as this app required root access)
This successfully unlocked my phone. I was able to call receive messages with new carrier.
I installed some more general apps used it for 5 days.
Sudddenly i started facing network issues. I was not able to make or receive calls. Strangely, I was getting data connection from network but not able to make or receive calls. I could not register on any network.
I tried running GalxSimUnlock app again and it said Unable to read NV data.Since I was naive i tried reinstalling the stock ROM and SIYAH kernel to see if it helps. It didnt.
When i researched further i came to know there's probably something wrong in the NV_data.bin file in EFS . But i hadnt taken backup of EFS previously. Now can anythng be done to restore the EFS and make the phone work? Please help me....
When i run GalaxSimUnlock app it shows everything in green except IMEI number which it blinks in red. But I am able to see a IMEI number and it doesnt look like something default. I am getting everything else MAC id, baseband version etc.
Thanks everybody...please forgive my language if not upto the mark as i am pretty naive about this stuff.

Please Review this thread [GUIDE] Recover your IMEI in 9 steps.
If you have specific question on the process, you can post this thread as well.
If that does not work and you need further help, please post in Galaxy S II Q&A, Help & Troubleshooting

Hey Buddy....Thanks for replying....i just saw you have written you flashed the original ROM on your device again...but as I wrote I have flashed another ROM and didnt take back up of original one and cannot find the SKT korea S2 ROm for this one...Is it ok if i employ the procedure told by you without flashing original ROM...what is CSC? Is there anything else you wanna tell me before i start the process? please forgive for my ignorance Im quite new to all this...

You will have to ask on the thread I linked regarding the Rom. You will have the right experts for your device there.
CSC is sales code., you can check your ROM CSC by dialling *#1234# . First two digits represents country and last three represents release time.

ok thanks...i will post the question there

Per Suggestion from my Collegue @It_ler,
The kernel you have is older. Latest SiyahKernel for the stock JB ROM he has on his device is SiyahKernel S2-v5.0.1.
If you have questions about the kernel, then use the [KERNEL][REF][Q&A] Siyah 5.0+[ICS/CM10] 6.0b5+[JB/CM10.1] +DISCUSSION+. NON-DEV!!! (SiyahKernel discussion) thread.

Phone not allowed MM#6 @ Galaxy S

Hello guys!
Recently i unlock my Galaxy S using the Galaxy_S Unlock app from the market (i've read a thread about it here).
And i've been using my phone with Personal Argentina (a carrier from Argentina) for a few days now, but today i start getting the Phone not allowed MM#6 error.
I bought the phone in Canada, and it was locked for Rogers.
I have a few questions :
is this IMEI related?, i think that the unlock method does something to the IMEI, and i tried to restore the backup that i've created with the app, but it says that there's nothing to restore..
There is any known solutions?, i've been searching the forums but no one seems to know how to fix this issue.
I've also bought the DaGentooBoy App for unlocking the Phone (it was about 5 dollars), but it doesn't fix my problem.
Thanks in advance.
EDIT :
I just read this :
http://forum.xda-developers.com/showthread.php?t=863209
where should i post this question?
Omg this forum moves so fast, i'm at 3rd page already.
I'll up this thread one more time to see if anyone can help me.
I've done some attemps using this thread :
http://forum.xda-developers.com/showthread.php?t=881162
Before doing that i flash back to 2.1 stock using Odin, and after those steps i got this generic IMEI :
004999010640000
That;s not my Phone's IMEI, and it's blocked by the Carriers in Argentina, so i can't use my phone.
Any ideas?, maybe some keyword that i can search on Google?
Thanks!
I'm in Bolivia. I have a samsung galaxy s, I unlocked with SUperOneClick (for rooting) and sgs tool to unlock it. Then after using a local carrier for about two weeks my phone got the mm#6 error. I was looking for solutions, and then my brother realized that I have to register the phone with the line (IMEI with line). Here in Bolivia exists a law that block phones if they are not registered at someones name and Id. So with nothing to lose, I called assitance of the carrier and register the IMEI I found in the Android menu (About phone>status>IMEI) with the GSM chip/line I have. Wait for 20 minutes and voilá! phone got signal and it's working now. I hope still working from now and on. SO IF YOU HAVE THIS TROUBLE CALL YOUR CARRIER AND REGISTER YOUR PHONE'S IMEI WITH THE LINE YOU ARE USING, IT'S SIMPLE. YOU CAN TRY THAT BEFORE GETTING INTO SOFTWARE STUFF.
HOPE THIS HELP SOMEBODY.
GOOD LUCK!

[Completed] Basic questions about installing a ROM on a Note 3

First, I have installed a ROM on my phone before and I followed very specific instructions. I am a developer in the land of microsoft so I recognize I am very much a newbie here.
Now, on to what I have now and what I want to do.
1. I have a Note 3. The SM-N9005. The baseband version is: N900W8.... suffice to say it is a canadian phone. If the rest of the baseband numbers are important I will post them, just ask.
2. I want to install the Alliance ROM, it seems to have what I am looking for.
3. When I rooted and ROMed my phone years ago I used the following thread: http://forum.xda-developers.com/showthread.php?t=2614772
4. Currently my phone is running a Jedi ROM from the vintage of that thread. However I must have made a mistake back then because the Hotspot feature does not work. Making the hotspot feature work again is my primary reason for undertaking this operation. The 4G works, I can use the Internet on the phone just fine. The wireless works I can connect to a wireless signal and use the internet that way (with mobile data off). The hotspot will allow a connection, but no data passes between the 4G (with Mobile Data On) connection and the connected computer. I have tried this with multiple computers to confirm its not the computers fault.
Back when I did this before I had to be careful to get the right CSC file and modem file and a few other steps.
With that background, my questions are below (if you need any more info to point me in the right direction, just ask):
Do I need to worry about CSC files, modem files and so on to Flash to Alliance ROM and still have everything work? I ran across a thread that said that some ROMs have all the CSC files in them, but I cannot find any direct information (or I missed it) about the Alliance ROM with regards to CSC files and the like.
I have TWRP installed on the phone and was planning to use that.. that install of TWRP is over 2 years old is there an update to TWRP that I should do or would it still work since it worked last time?
Last, but not least, the instructions say that if I am not installing from stock 4.4.2 or stock 5.0 that I should install stock first, then install the alliance rom. I visited the sammobile website and there are no ROMs for the USA or Canada there... am I missing something or should I just use the UK ROM from that website?
Thanks in advance for any help you can provide me on this endeavour.

Galaxy Note2 GT-N7105 LTE ( t0lte ) - suddenly sim locked again ???

Note 2 LTE - suddenly sim locked again ???
hint: only read the Bold letters to make it short
ok, im allmost ready to give up this time...dont know how many of these threads i read allways to find a sullution to my problem, but it seams i finally have to ask for help myself.
Yeah, this is my first post, but ive been arround for a while, anyway this time, i need your active suggestions...
the History:
The phone: Samsung Galaxy Note2 GT-N7105 LTE ( t0lte ): initially locked to the Austrian Carrier A1, but i bought it allready unlocked.
Back then 2013 managed to flash and root via clockworkmod and wanam light rom, without triggering knox - thanks to you guys in here...chears again for that...
I hardened the system quite good and gave it to my mums - not touching it for years -or hardly, finally 2016 seamed to be time for an update. Didnt care much for the knox anymore and simply updated recovery to TWRP 3.0.2 and cyanogenmod 13.0 - 20161118-NIGHTLY ( recconed simplest Marshmallow upgrade ), installed the basics - thats it - left the phone with my mum again.
Got back few weeks later - i had realized my mum wasnt reachable on her phone anymore - figured she could still make calls herself, strangly she even would still be reachable when called via landline , but for some reason not from any cellular networks - so i went for a visit and thinking it might simply be a problem with her sim - i swaped her sim for mine - when turning the phone back on it now asked me for an SIM-unlock code...WTF!!! (and befor anybody asks my mums sim network was never A1 either)
- everything else seamed fin - imei and baseband still ok, sys stable as far as i could tell - only thing i noticed it had updated cm-13.0-20161122-NIGHTLY on its own...
Swaping SIMs didnt yeald any effet - so since that was the only thing that caught my eye i reverted back to 20161118-NIGHTLY and then back to my old wanamlight and finally even to original stock rom - problem persisted.
Searching i found 100 links like How to Unlock Your Samsung Galaxy S3 & Note 2 (No Rooting) , but no luck
Final resort, i even purchased an unlock code from UnLockBase but even that didnt work ...WTF!!!
So back to square one i found this Baseband Unknown and IMEI Null NOW WORKING | Samsung Galaxy Note II GT-N7100, N7105
But even if my imei and my baseband was ok i thought perhaps the efs migh have some taken some kind a hit - so i searched eveywhere and found my old 2013 backups: PIT-File and EFS-partition (DDed via terminal) - so i backedup the existing efs and restored the old-EFS-Backup back again - then i even used Kies to revert everything to the last bit.....but no luck....
..also UnLockBase-Code still doesnt work - (btw. the also provide an unfreez code but ...all the same ) so i rooted again and tried GalaxSIM unlock says unsupported Model....whatever!???!!!:crying:
only thing left is perhaps: buy a cheap mainboard via aliexpress and perhaps take allong the imei from the old motherboard...
but i hate giving up!!!
What do you guys think? ...any suggestions
...sorry for having to read all that...tried to help a little there
update: made a second thread in the N7100 forum part link

You would probably have better luck asking this in your device specific forum as the members there are more familiar with your model and its particular issues, it wouldn't surprise me if someone in that forum hasn't already had this issue on this model.

I've turned it over and chewed on it for a minute but with the troubleshooting that you've already done I can't for the life of me think of other steps for you to try because you've done everything I would do already plus I'm not familiar with your exact model. I'll keep it on simmer and hopefully a butterfly will land on my shoulder and bring something to mind that might help you. You've pretty much covered all the bases already.

[Completed] Help!! Galaxy J100H not registered on network.

Greetings, sharing here my particular problem from top to bottom just to take advice in general.
First of all, I live in Cuba, so my one and only network is Cubacel which runs GSM 900 mhz, so far so good with most phones.
I am between phones so I boorrowed this used J100h from a friend, which received it as a gift and has never been used. I performed a hard reset to wipe password, data, etc. Phone boots ok but no calls with cuban SIM.
The curious thing is that it does recognizes Cubacel network, it evens shows the changes on signal intensity. Bu when I try to manually add it, it finds and displays the network by its name, but reports an error when trying to register.
After 3 days of internet search I´ve narrowed to the following: I suspect the phone was unlocked or flashed previously, there is no network promo when turning on the phone but there is chinese rooting software installed and the cell is, or seems via root checker, rooted. Thought an extra /01 after the IMEI was a sign of corruption until I leraned about IMEI SV. Anyway, following this thought installed busybox and root explorer, checked efs folder, finding subfolders such as imei, factory app, etc, BUT NO .NV file. inside imei folder ther is a imeino1 file with the correct imei, but no .nv file outside. Is this fixable?? GSII repair doesnt work because seems theres is an error with the busy box install, what gives me doubts if the phone is really rooted, and if i need to be online to install busybox properly.
So, If I decide to try and flash stock rom and see if this fixes the problem here is my main doubt, which may seem obvious for some but i simply can figure out. Which stock rom version do I choose? the product code of the cell is ITV, and the bootloader also points to the italian version but the currently installed rom ends in AOG2, seemingly a greek version. I live in Cuba and everywhere I look people say that since the telephone is sim free you can install any rom, but the is no "any" or standard rom either in samsung firware o sammobile. Do I flash the same rom? do I flash the one matching the bootloader? Which stock rom version should I choose?
Very much appreciated if you have gone so far in this reading and have some piece of advice. Also excuse terrible English.
Hi !
I see plenty of firmwares on samsung website so pick one and see how it works , it doesn`t matter the region , you won`t damage anything , maybe the modifications that has been made on the device borked the network , clean stock firmware flash may resurrect it and try the one which matches the bootloader
You may have a look here as well https://forum.xda-developers.com/android/development/rom-gennxt-prerooted-stock-t3126368
Good luck !

Unknown IMEI after flashing Superman ROM for S7

Hello everyone, recently I've flashed the Superman ROM V.3.0.1 on my S7 Edge and everything was fine until I went to general settings on my phone and saw my IMEI is now UNKNOWN. I know this thread may be already solved, and yes, these days I was looking for answers for my problem but I need to know for sure what alternatives I have to recover my IMEI. I have to mention, my phone is 100% original, it has its own IMEI from the beginning, not a copy or MTK device. I saw some sollutions based on some kind of programs to restore manually the IMEI with a command, and this method for me it's not like the best thing to do in this situation..
When I am dialing *#06# I receive the following information: " SM-G935F is not supported on showIMEI ".
I've checked through TWRP ( version 3.1.1.0 ) the partition EFS, is still there ( it has 2mb ). What do you guys think about this? Flashing the stock ROM from sammobile may solve my problem? What alternatives do I have?
Thank you!
