Hello everyone,
I have a Samsung Galaxy S2 i9100 and I'm trying to install Lineage OS 7.1. The flashing goes smoothly but when it reboots, I type the SIM's pin and I get the "SIM operation failed" message. I remember I messed around with the efs folder some years ago but after that I have been able to flash several ROMs, CM 12.1 for instance. I tried to flash CM 13 but I did ran into the same problem, I couldn't go beyond the SIM's pin screen.
I'm trying to use EFS Professional but in the Device Filters menu there's no Galaxy SII and no matter what device I choose, the Device Partition window stays blank. I can not do anything with it.
The current IMEI in my phone right now is 004999xxxxxxxxx. How can I reset it to the right one? I'm desperate!
Try reinstalling 4.1.2 With Odin and reflash LineageOS :laugh:
Following is worked for me on my Samsung Galaxy S3 i9300 with LineageOS 14.1:
1. Flash original ROM with Odin. (if at this moment IMEI is not correct use program "Samsung Tool" to manually edit IMEI)
2. In security setting, set SIM card lock to none. (After this you should permanently disable SIM pin request on startup on every new ROM)
3. Flash custom TWRP recovery with Odin.
4. Root phone.
5. Make nandroid backup of EFS using TWRP.
6. Wipe cache, system, boot, data and flash custom ROM (do not reboot system after flash).
7. After flashing custom ROM, restore EFS using TWRP.
8. Flash Opengapps, wipe cache, dalvik cache and reboot system.
9. Set everything up Google account...etc.
10. In options check if IMEI is valid. (If is not, reboot to recovery and try again to restore EFS)
If you don't have working cellular network after flashing custom ROM, read following:
From Play Store install app "Cell Network Reset".
Open app and run "Reset Cell Network". (This step is weird because some times after few minutes i get working network, some times after few seconds. Also some times i need to run "Reset Cell Network" few times in a row to get the network working)
I hope it will work for you

hi. i tried to flash avatar on my rooted i9300 and i got into boot loop so i some how came out of that by flashing stock firmware via odin. but i could not get mobile network, so i tried to restore efs folder by EFS professional software. that is where again i got in to BOOT LOOP. (like never ending). since i had already experience this problem so i started with wiping data/ factory reset, wipe cache, use odin to flash stock firmware/checkrom/rescue rom. as far as i could read every possible thing, i tried to follow but all i am stuck with is a never ending boot loop which takes me up to asking Google account details then goes back to reboot and i9300 logo and same cycle.
one more thing i have removed sim card and sd card, but still in rebooting phase as i mentioned i can go up to Google account details. i can see network signal on top even if i have removed my sim card. Is there anyway out..
Wiping data factory reset does not wipe previous system rom only reset's it you need to wipe your system but make sure you install a rom soon has you have done it.I suggest installing philz recovery it as got a built in wipe before installing a rom feature.Follow this guide http://forum.xda-developers.com/showthread.php?t=1911726 look at Wiping & Flashing - Cleaner Flashing Method :good:
You can also use this http://forum.xda-developers.com/showthread.php?t=1832326 but be very careful make sure you have a rom ready to install on your sd card
A few years ago I installed CM11 which gave my phone a new boost. A few months ago I noticed the development of CM13 for this device. With the arrival of the snapshots I decided it's time to upgrade.
I'm familiar with the CM13 on another device (Galaxy Tab 2) so I think I know how it works.
I tried several times but the problem is that my SIMcard is not detected.
I use this device as my daily phone, so luckily every time after restoring to my current CM11 everything works fine again.
Current
CM version: 11-20141115-SNAPSHOT-M12-i9300 (smallband I9300XXUGNA8)
TWRP version: TWRP 3.0.2-1
(Living in the Netherlands)
To install:
cm-13.0-20160820-SNAPSHOT-ZNH5YAO0J2-i9300
open_gapps-arm-6.0-mini-20160901
1. sync several apps
2. reboot to TWRP recovery
3. full backup to External SD
4. wipe (factory reset)
5. advanced wipe (cache, dalvik cache, data, system)
6. connect USB-OTG
7. install (in queue: cm-13.0 + open_gapps)
=> no errors
8. wipe cache, dalvik cache
9. reboot to system
during configure: No simcard detected
10. ignore
11 finish configure
12 enable root
sim working: no ( but with sim pincode ON not possible to pass lockscreen )
imei: correct number (checked with DevCheck)
smallband: yes (I9300XXUGND1)
contacts: yes
Also tried to reboot and
To shutdown + remove sim + boot + shutdown + reseat sim + boot
=> nothing
Revert to CM11 and everything works like it should.
The whole world is happy with this CM13 build (and newer nightlies), so I can't believe it has something to do with the rom. While I don't have any problems with my phone on CM11 I'm sure, my phone is fine.
So, what am I doing wrong? Wrong combination of software? Something with partitions, filesystem, etc (never played with that)?
Something with my current carrier Vodafone (sim is simlock free) combined with the XX modem and radio (while should need XP for Netherlands)???
I'm out of options. Please help.
Thanks in advance, René
//Edit
Could it be something to do with the TWRP version I use? Older forum posts (12-2015) suggests that newer versions then 2.8.6.0 wouldn't flash radio and modem correct.
Is it possible to flash an older version of TWRP over the current on...?
I'm in the exact same boat except I had TW 4.1.2 before trying CM13
Phone needs to be running these latest bootloader and modem.

These?
Sorry, I meant "the". Damn spell check.
Good morning to you all, and thanks in advance if you can help me.
I just received an Ace 4 Neo from a neighbor who asked me to 'make it faster' and 'newer'. Naturally, with the Stock ROM what Samsung overloads, I wasn't going to do nothing as close. I came to the always loyal xda and found the Mega Thread of Ace 4 Neo: https://forum.xda-developers.com/ace-4/development/rom-cyanogenmod-11-12-13-ace-4-neo-ace-t3627637
I put into the phone the oldest Stock ROM available from the same origin country and carrier (TIGO - Paraguay), and after installed Custom Recovery TWRP 3.1.1-0 and tried to install a Custom ROM. There is where my problems started.
First, I tried to put CM13 or MIUI (Android 6.x) with no success. The phone when turning on just showed the model and stayed there. The only change was a red exclamation sign on the upper part of the screen. (Possibly, this will be helpful for you: When installing, the result said [ ] instead of [/system])
After 6 failures with each one, I desisted and instead tried with CM12.1 and this one successfully installed. I also tried to use OpenGApps Pico (as I really messed up trying to find how to install the GApps of the thread), and the phone turned on "without problems" (the CM in fact started, but the red exclamation point is still there).
After 8 minutes configuring the GApps, I configured the Google Account and such. However, I went to Play Store for naturally install WhatsApp, Facebook, Twitter... The common things.
Surprise! The phone when installing suddenly rebooted. When turned on again, the home screen closed and opened 4-5 times in 20 seconds and rebooted again. It maintained on that loop over and over.
So, am I doing something wrong? Or do you know about how to fix any of the previous issues?
As a final note, because the Mega Thread doesn't have the classic installing instructions, after navigation for 2 hours I constructed this steps:
1. Reboot to Custom Recovery
2. Wipe > Advanced Wipe > Everything except Internal Memory and SD Card (Dalvik + System + other two things)
3. Install ROM
4. Wipe Cache/Dalvik Cache (the button what shows there)
4. Install GApps
5. Wipe again Cache
6. Reboot
Again, thanks in advance.
Hi, @Pedreo1997. You need wipe internal storage, too.
Step-by-step install custom ROMs:
Flash oldest stock ROM with Odin.
Reboot system > use 1-2 minutes ( for sure )
Install TWRP 3.x.x
Wipe everything except sdcard.
Wipe > advance wipe > check system > option > repair
Install ROM and Gapps.
Reboot and enjoy

I hope it will work for you
good.
Hello, I have a Samsung j2 phone (model j200g) and it shows me a black screen (in place of the Samsung logo) after the boot, and I want a solution from you, I will show you what I did after this problem occurred.
- When this problem occurred, I did not know what to do, so I had to flash it with its own file, and after the success of the flashing process, the same problem remained.
**I tried to flash it several times, but same problem, so I had to flash it with a custom ROM (lineage os 14.1).
-After failed attempts to flash, I installed the recovery module (twrp) and copied the custom rom file (lineage os 14.1) to the phone via otg, I flashed the custom and the installation succeeded. I turned on the phone and the “samsung galaxy j2” screen appeared, and then the custom ROM boot screen came, but here the boot (the circle that rotates for the custom ROM) remained as it was moving indefinitely. I left it for a whole day and it is still in this state.
I want you to solve this problem. I spent days looking for a solution to this problem.
I understand you have flashed full Samsung ROM/firmware BL AP CP CSC from Odin3, then installed TWRP and installed LineageOS on boot + system. In case you haven't already done, disable dm-verity with this zip
https://build.nethunter.com/android-tools/no-verity-opt-encrypt
don't forget to format Data (wipe - advanced - format - type 'yes')
