Hi everybody!
For some time I've been trying to flash LineageOS on my friends S3 (I9300) improted from China.
It's currently on 4.3 ZCUBML1 firmware. Every time I flash LineageOS the phone looses it's IMEI and baseband and the SIM card stops being recognized.
I tried flashing modem I extracted from stock rom over it, using patched modems, restoring backed up EFS partition etc. I've run out of ideas.
Any solutions?
The phone is running the latest modem and boot loader?
Yes, I think so. I downloaded and flashed the latest firmware from samsung-updates.com.
@KarKlim Before loosing your baseband is it MK6 ??

Hi Guys,
I already posted a thread that I was not able to connect to network after upgrading to 4.3. here
http://forum.xda-developers.com/showthread.php?t=2554836
I have successfully solved the no network problem with the help of the patched mg4 modem and moving back to my stock 4.1.2 Samsung ROM
Now i decided that i will backup my EFS this time and do everything perfectly and try the leaked 4.3 European release and did all the backups like EFS pro backup in PC and also Aroma Installer EFS backup to SD and Internal card.
I have got the complete EFS backup and hence I wanted to try the new 4.3 Leaked firmware
I downloaded the ROM flashed via odin and rooted it and again "no network" error and tried to restore the EFS pro backup from PC
But it kept saying"your device is not perm rooted,only qualcomm tools available"
So i downloaded supersu 1.80.apk and flashed the zip file.Still same error.
So i flashed the aroma EFS installer again and restored the EFS and it was successful
I restarted the phone and i thought the network will be back as i restored EFS but again i faced "no network"
I then flashed the patched mg4 modem again and then too same problem.
I did not know how to solve this though i rightly backedup and restored EFS
The only solution now was to do like before and go back to stock UAE 4.1.2 and flashing the patched modem.
I got the network back.
So i beleive the only way to use my phone with network is to stay with the UAE 4.1.2 stock ROM and any other ROM will give me "no network issue" though I have the EFS backup correctly? I can never upgrade right?
Can the experts tell me where im doing a mistake if there is something wrong in my methods.
Waiting your replies
Thanks in advance

Same problem with me http://forum.xda-developers.com/showthread.php?t=2572397
Hi, When ever i hard reboot my phone my efs gets corrupted, but for soft reboot it is good. In stock rom no such problem, but i tried many custom roms, it happens. Initially when the rom is installed it dosen't happen. After a few days, after installing a few apps it happens. I am not finding any help in this matter, please help.
Also can i change csc to inu (india) in custom rom, I have installed latest modem for my country (india). But my signal keeps fluctuating. I am using Slimkat 5.9 weekly 4982.
Thanks a lot.
I brought galaxy s2 from three carrier in UK. Accidently I hard brick my phone and flash firmware from sammobile. Com via odin . Everything is fine in this jellybean stock rom. Now I can't flash any custom rom. It gives status 7 errors. I tried many roms. I updated cmw recovery to latest version by rom manager but still can't flash any. Does other stock rom changes s2 model number. For now it's showing gt i9100.Was it att or tmobile or skyrocket or else when I brought it? Why can't I flash rom? Why there is no twrp available for galaxy s2 this model? Help me guys. God bless you!
I've had that error on kk ROMs when tried to flash from old recovery. If I remember you should have at least 6.0.47 recovery version. Try to flash Gustavo_s kernel,Apollo or doromanx and try to flash again.
When flashing via recovery cwm has a security check that checks the model of your phone to the model of what rom you are flashing . If they do not match It returns status 7 error which prevents from installing wrong rom and hardbricking your phone .
Error can happen when recovery is not updated . A simple fix is to make sure you are on the latest recovery .
TWRP : I think it doesn't have the security check however :
INSTALLING WRONG ROM WILL MOST LIKELY HARD BRICK YOUR DEVICE
I am sure you know that already .
There is TWRP for i9100 . There are methods to remove the security check via editing the rom but it is not recommended

Thank you guys for reply. I flash kernel once and it was struck on boot screen. As you said there is twrp available for galaxy s2. I have heard lot of positive vibes about twrp. But in their official website s2 gt I9100 is not listed. It's only for s2 Exhilarate SGH-i577. Is it correct? Any working twrp download link for particular I9100 model? I have heard that twrp are less likely to status 7 errors.
Apparently twrp is not officially supported by i9100 however there are ports by other people . I know because of my last attempt to install cm11 snapshot m8 after flashing gone abit wrong I was getting status 7 error even on my backups .
Try installing (or using kernel) omni-rom . It is available with cwm or twrp kernels ... not sure how it fits with carriers though ...

How did you recover from last brick ? Did you flashed stuff or had the mainboard changed ?
Hi,
I have already backup my stock rom using TWRP before flashing custom roms from this forum, after that, I use restore in TWRP to back to stock
After reboot, I was asked as if my tablet is fleshy started, then MOBILE PHONE & DATA is broken...
Here are my P7500 P4 (3G) symptoms :
1) Settings->About device->Status: MDM UNKNOWN...
2) SIM seems partially working, radio signal okay, Carrier detected, about my phone no. is not working... & there is no apps to dial out...
3) All my PHONE-related APKs disappear, I already checked Setting->Application, Phone is not running at all
Plz. help me... I did not play with the mdm partition at all, I swear...
Did you restore your backup with the same TWRP version ?
I believe you have no other option than to flash a new fresh stock Rom from Odin.
But I could not download any stock firmware from sammobile...
I registered as a free member and logged in, but in the firmware section, was automatically logout... ...
Hello all. After trying to get various Custom ROMs working, CM 11, 13 or Slimkat 9, unofficial 9.1, no version worked properly with phone signal.. I ended up experimenting with flashing modems or going back to stock firmware and doing all the steps from there but still couldn't make it work.
Stock firmware that came with the phone 4.1.2 (KIES_HOME_I9300XXEMG4_I9300OXAEMG4_1314436_REV00_user_low_ship) was perfectly fine also (I9300XXUGPE1_I9300AMNGPF1_I9300BVUGNB2_HOME) which it's 4.3 from orange spain was fine, tried one from my country and ran fine, also 4.3. Then I found out about this thread:
https://forum.xda-developers.com/galaxy-s3/help/guide-emergency-calls-problem-siii-i9300-t2752541 and by mistake I flashed first the patched modem following this order of events :
4.1.2 STOCK > 4.3 Movistar STOCK > Slimkat Unofficial 9.1 latest > all fine but no signal. Then:
4.1.2 STOCK > 4.3 Movistar STOCK > Slimkat Unofficial 9.1 latest > flashed patched modem from thread above, boot loop.
Then tried to flash the original stock from the phone, didn't work. Stock from my country doesn't work. Stock from spain doesn't work but it goes a bit further in the first boot going to android updating apps , it finishes updating apps and goes into boot loop. That's it. At the moment I can flash with odin or go into downloading mode. When the phone is off, it can manage to charge the battery without problem.
How should i proceed now?
Thank you, I hope you can help or advice me.
EDIT 1: I also tried to flash the firmware from the above thread, the i9300 UK (BTU) but no luck.

Odin can't flash a stock ROM or you can flash a stock ROM but the ROM doesn't boot all the way?

Hey again audit13. It can flash the ROM fine but it gets stuck in boot loop. I'm trying to find the stock ROM with the 3 files but no luck yet, im hoping that can get to do a proper reset factory of everything.
Are you flashing the latest stock ROM from sammobile.com? This file would have everything in one file.

Version

PDA
I9300XXUGPE1
CSC
I9300AMNGPF1
This one gets to passed the first time the loop till android updating apps dialogue, then goes to boot loop.
Are you performing a factory wipe using stock recovery before booting the flashed stock ROM for the first time?

Wiped, then did a reboot in the default recovery mode. All went to normal again. I still need to figure out how to get a Custom ROM without screwing up everything again.. Thanks for your quick support.
Glad you got it working. One thing I would not recommend is flashing a patched modem. The stock modem is the best modem in my opinion.
