Please BIG PROBLEM with 6.1 Lightening

This morning my friend give to me a gs2 new but i haven't read what version is.
But i started to download the new lightnening 6.1 and open Odin .
All seems to be correct but after the reboot the sim card dont work.
I try everything ! But the only way to use the phone is flashing by odin the KH3 firmware .
Can anyone tell me if i made some wrong thing ?
The gs2 can be rooted first ? no ?
i can flash the 6.1 lightening in every case or not ?
Thank's

Where do you live, what country?
Before you flashed with Odin, did you close Samsung Kies with windows taskmanager (Kies Trayagent and KiesPDLR )?

What the hell! I got the same problem today and I think i´m a quiet experienced user... Under "Baseband" there is just "Unkwown" stated I flashed manually Modems in Odin, restored a backup and tried it in a Stock-rom... This all happened after flashing the Frankenstein KH4.

Not wiped your IMEI i hope....

It seems that you lost your IMEI number. If you have backed up your /efs folder you can easily restore it. If not you might be able to get a generic IMEI which lets you use your phone again.
There are several threads here on xda and oder sites. There is even a youtube video how to restore your IMEI. Good luck.

My efs folder is backed up and still on my sdcard... I just have to overwrite the old efs folder right? Because i´ve done this and nothing changed. The phone is just completly ignoring my simcard (I also tried different simcards).
PS: And yes *#06# gives me an erased field

Flash back to stock KH3, root it, backup the /efs folder, flash Lite'ning and restore the /efs folder from the backup

I tried now almost everything! Flashed stock, flashed Lightning, restored backup folder and tried to restore a generic one with the youtube tutorial but everything does´nt help meto get rid the proplem with the undetected simcard...

One is your IMEI correct
Two have you flashed a clean stock rom ONLY
Three have you cleaned the sim card contacts and on the phone
Four dialling *#1234# are you showing the correct CSC.
Five are you getting a network connection when entering manual details of the network APN etc .
As you have broken a new phone within a day i suggest you take it to a service centre .
Follow that up by reading the guides before flashing as plainly you don't understand what you are doing .

I´ve just flashed stock KH4. The result was the gone IMEI! I own this device now since two months! Dude dont blame me for this... I´m just not able to restore my backed up IMEI.
My english is not the best but you're a real british guy and you have the possibility to write useful and understandable, particularly with this amount of posts.

Maybe your SGS2 was locked on some network. But.. if you erased EFS, you have to copy back all files and reboot phone. How did youo backe up /EFS? There is a HC-kTool app somwhere on XDA which can backup and restore EFS.
If you manage to restore EFS, run sgs2 sim unlock app to find unlock code (if its sim-locked)
You should explain how did you backup /efs and how did you tried to restore. Maybe restore procedure is not correct.

it´s an fully unlocked device. I have a tar packed backup of the efs folder on my sdcard, but can´t remember when and why I´ve done this. Until now I just overwrote the old efs folder with the original one (i´m not quite sure if it´s a real backup. Is there any way to find that out?) , but is it normal that I don´t even got an generic IMEI?

I had the exact problem with my cousin's SGS II, brand new phone on orange network, when I flashed Lite'ning rom 6.1, got no baseband and no IMEI, flash back to stock XXKH3 and everything fine. Problem for Mr Lite'ning to sort I think. Thing is my release SGS II runs it fine

Need help to fix imei issue

In the beginning, i can use my note 3 n9005 SFR as usual. But once i tried flashing rom, it showed as error (fail) because I chose BL instead of AP. And i tried to fix it by follow the instructions as Mr. Firasusman suggest me as said in the this link http://forum.xda-developers.com/showthread.php?t=2614787. It solved the problem my phone can now get into the normal screen but i found a new problem. I put in sim card but there is no network signal and I also lost imei when i checked in phone status. What should I do to fix this problem? Anyone, please help me. Thanks a lot.
IMEI = Unknown
S/N change
Baseband ok

Check whether EFS folder is backed up by flashed rom in sdcard. If your lucky you can use backup file to get imei number back. Few posts also suggest that flashing back stock rom also get back imei. I am not sure of it. Better back up efs to your pc.

EFS is a folder in phone's file system which saves your phone model, IMEI number and lot more details, Important folder. Flashing ROM the efs folder got corrupted causing the loss of imei number. Try "radicalisto" reply and update the issue.

This fix never worked? - hmm,you have lost your EFS/IMEI somehow then. Does *#06# bring up an IMEI? - if not you'll have to search around for how to fix your IMEI (It can be done)

still need help here.

Changed csc, lost signal, need help

Hello, yesterday i bought used samsung galaxy s7 edge dual, sm-g935fd. It was rooted, owner said root was done to flash a rom to let phone see two sims. Went back home, started to install apps, and saw that snapchat doesnt work with rooted phone, so turned superSU, chose full unroot, phone did restart but stuck on bootloop. All I saw, was csc:g935f0xx1bph1 and pda:G935FXXU1BPLB. Could't find matching pda and csc roms, so installed another, for g935f, and everything worked fine, except from network, it only says emergency calls only and no signal, but it finds that my sim is from tele2.
On other thread i saw that i can use home_csc for my csc code, and any other pda, bl, ap, tried that and odin failed to flash it, so now flashed netherlands stock rom that changed my AP:G935FXXU1DQEF CP:G935FXXU1DQD7 CSC:G935FPHN1DQD1 Model: SM-G935F/DS.
Can you guys help me to get my network signal working again? I think that matching software for my phone would fix it, but i cant find which one to flash, or is there anything else that could have caused that?
Thank you for your help.

Sounds like your EFS is corrupted...
*Encrypted File System (EFS) | The EFS refers to a folder called EFS which can store information like meid, imei, serial number, config, diag settings and radio settings, etc in an encrypted format at the file system level stores. So it is very neccessary for us to backup EFS before flashing ROMs.*

i dont think that they can help me. I am not really good in flashing, because english is not my native language so i dont know what kernel means, whats the difference between firmware and software, and even rom, but i think that i have wrong bl/ap/csc/pda or something like that. Found that F in sm g935fd means it is international, looks like i can flash any country unbranded stock rom, but somehow it wont work for me, and i cant believe i did that much damage just by clicking on unroot in superSU app..

No signal after restore with TWRP

Hello, I have a problem and I do not know how to solve it. On my Redmi 2TD dead immc memory, I ordered a new motherboard put it on, everything worked. I decided to restore a full archive made with TWRP - made with the old motherboard. Then I rebuilt my IMEI. Now I have sim card, but no signal and the settings are only 2G. It also sees satellites, but does not locate. Maybe I did not have to restore the system, just the data from the old motherboard ?
Has this problem solution ?
Sorry for my bad english

If you have problem with network signal it may have something to do with firmware/bootloader version. Try kitkat or lollipop. You can find on download section

Phone locked in setup after flashing decrypt and magisk.

My asus_x00tdb had a lock icon on the top left corner after I flashed decrypt and magisk. Also, the IP and MAC addresses are unavailable. Did I do something wrong?

okay so after flashing with twrp I reboot my phone to system then I get to the phone set up ( like the set up you face after factory resetting). In that point i can see that there is a lock logo in the notification Bar on the top left corner of the screen.
After that when I get to "connect to a wireless network" slide kind of thing there is no IP and MAC addresses. So I cannot connect to a network.
