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.
Hi.
I have a Xiaomi Mi2S that doesn't connect to any cell networks.
I'm using CyanogenMod 11 nightlies, and after an update the phone lost its IMEI number. I had taken a backup of the NVRAM using EFS Professional, but when I looked for it the files where 0 bytes in length (probably a hard disk problem on my computer)
After trying a lot of stuff (installing stock MIUI, putting the phone in diag mode and installing a bunch of drivers), I managed to restore the IMEI number, but the phone still can't connect to the network.
I have tried a SIM from another company and it doesn't work. And my SIM works correctly in other phones, so I think that is not a SIM problem.
I don't know what to do... I tried flashing different ROMS, tried flashing a new baseband radio, but I can't get it to work! Is the phone lost???
Can anyone help me? I would appreciate it very much!!!!
Hi, I can't find anything relevant on XDA for your device and issue.
You can try asking for help from this thread dedicated to your device ,
http://forum.xda-developers.com/showthread.php?t=2274565&page=2
Or if that doesn't help , then from here,
http://forum.xda-developers.com/mi-2/help
Good luck!
Thanks!
Thank you for your help! I have posted in the thread you provided... let's hope that I can find a solution for this. I don't want the Android version of an iPod
I did a factory reset (did not flash a rom) to my Note 4 (SH-N910w8) & now it seems that my EFS part is wiped or corrupt. No IEMI# as well as when I go into the service menu on the phone there is no command options! I do have my imei # from the box but I don't now how to rebuild the EFS partition so I can get back on the networks. Any help would be appreciated. Thank you!
Hi, thank you for using XDA Assist. Try flashing the stock firmware with Odin. If you have further questions you can ask in your device's specific forum, http://forum.xda-developers.com/note-4
Hi im new in this forum, I tried to search extensively in this forum and some people have similar issues like me.
I have a Samsung Galaxy note 2 GT-N7100.
When I received this phone was in 4.3 jelly bean and i made a successful upgrade to 4.4.2 kit kat, and I don't remember well why, but I needed to get back to 4.3 and the process corrupted my imei to generic one.
I tried everything to fix it like changing modems, flashing another roms and nothing works, so... a few weeks I contact a Poland guy who fixes my corrupted imei remotely and everything was fine, my original imei back.
Now I have my imei, but same issue, No network registered, I have signal network, also my sim is recognised (virgin mobile) and I was researching here about that, but nothing works...
My phone is not reported or something like that, so I don't know what can I do now
I don't know what any info you guys need to help me
Today i'm testing with stock firmware 4.3 (i'm from Chile) and trying the N7100UBUEMK4 ROM, flashed "Patched_N7100_MK4_KERNEL" and "Patched_N7100_XXUEMJ5_Modem" trying to fix this issue, but nothing change. Also, this solution kills my wifi, so I'm discarding this option for now
Sorry for my english and thanks for your time
PS: I need to add some information, but i don't know if is relevant, when I go to the network configuration to add "manually" a network show me three different companies (Movistar, Entel and Claro) (and I'm Virgin mobile) "Movistar" seems to be "unlocked" but it fails when It try it "Cannot connect now try later". Claro and Entel immediatly fail

Greetings and welcome to assist. I think the issue maybe related to downgrading, have you tired using kies emergency firmware recovery ? That should put the phone back to its original state
Good Luck

Hi, and thanks for welcoming!.
I was trying right now but Kies doesn't recognising my N7100, but Odin did it, is there a pre requirement for kies?
If I don't open Odin, kies does nothing, but If I open Odin first, and then Kies... Says "Connecting" and after a time said: "Device not responding"
I did not know about Kies emergency firmware recovery so I was following some tutorial, and it said I must be in Download mode, etc.
Anyway, I think my device is "clean" at the moment, after flashing 4.3 stock from odin, I didn't root or flashed custom recovery at the moment

Do you have the drivers installed ? You can try smart switch as well as kies and just select emergency firmware then follow the instructions. There is always mskips tookit as well, he has a thread in the n2 forums plus skipsoft.net
Good Luck

Drivers okey, I tried Smart Switch and recognize my N7100 but can not use the emergency firmware recovery, says I can not initialize.
And I can not download mskip's toolkit right now, the server is down apparently: crying:
If toolkit fails do I have a chance with another solution? I'm running out of ideas on how to fix this
Thanks for your time
EDIT: skipsoft is back, I'm gonna try it now
EDIT2: Okey, I'm kinda lost right now, with this tool (mskip toolkit) it looks amazing, a lot of options, but I don't find nothing that can help me with my issue, about flashing stock firmwares I assume I must download them first, but I really tested a lot of roms (stock and custom) and I don't know how to identify the real problem, if is a modem problem, or just the sim doesn't works in this device

Smart switch not initializing is a concern, is there an emergency firmware package on mksips ? If not try using this to get the correct firmware for your device

Verify whether your IMEI is still intact.
Go to:
system settings>about phone>status
or
system settings>about>status>information
or
system settings>about>information
Or whatever similar settings that you have, then check to see if your IMEI number is shown.
I DO NOT PROVIDE HELP IN PM, KEEP IT IN THE THREADS WHERE EVERYONE CAN SHARE
Thanks for your replies. Yes my IMEI is there but its not the same as it is on the back of the phone. However, the first time i flashed the stock ROM it was all the same but i still had this problem of Network not registered.

Are you sure that you flashed the correct firmware for your specific model number?
Have you tried another SIM? If you had the SIM in when you flashed it, it might have damaged the SIM somehow. That might not be your issue but it's worth checking.
Maybe you have conflicting data from before you flashed it, in this case you can try bioting to recovery then factory reset and wipe cache then reboot.

Yes i used the exact firmware for my model as well for my country. I think i have done what you proposing already. And for trying a different SIM i did try it too. I am really helpless right now
