Hallo everyone,
I don´t get my baseband running. And I think I tried nearly everything.
My baseband broke while running an ota and power off...
Anyways: I tied the following:
1. Backing up every partition with twrp.
2. flashing stock android via Odin with repartition and efs-clear -> data partition not working -> twrp repair -> working again.
3. wipe everything and flash stock recovery again without repartition and efs clear
4. restored nv_data.bin, disabled factory mode, added new serial
5. rebootet and again: baseband unknown.
6. rebooted to twrp and formatted efs with adb.
7. flashed modem again, restored nv_data.bin -> not working
8. Erased Flash reinstalled everythin new -> baseband unknown.
I just get no working basband, even if I put in my imei manually via xposed Imei changer.
Has anyone an idea.
Thanks!
Which firmware are you trying to flash and what model of the phone do you have?

I have an i9300 international version. It began freezing and boot looping.
Recovery and download mode were working. adb shell was working via recovery.
To figure out why it was bootlooping, I wanted to run adb logcat during boot, but to do this you need to enable usb debugging, and mine was disabled. Obviously I couldn't enable it because I couldn't boot, and even tried to enable via adb shell using the following steps:
/data/data/com.android.providers.settings/databases/settings.db: adb_enabled=1
and
/system/build.prop: persist.service.adb.enable=1
But I couldn't find the above sqlite database. In fact /data was empty and I couldn't access any system files via adb shell anyway.
So no usb debugging, which means the next step is flash a stock rom. I flashed I9300XXEMG4 (here) with Odin, wiped system,data,cache. Still bootlooping (samsung logo - kernel i9300 logo - samasung logo - kernel logo etc).
I read about the PIT file here. I read about how you should stay away from it at all costs. As this was a last ditch attempt I flashed the PIT file GT-I9300_mx_20120329.pit along with I9300XXEMG4.
The phone booted fine!
Unfortunately I just read this post about not coming back from EMG4... and I hadn't backed up the efs partition
Disclaimer: do not flash the PIT file unless you know what the hell you are doing.
P.S. if you have any problems with Odin not working (stuck before it starts flashing), close Odin, unplug USB and take the phone battery out, open Odin, put the battery in, boot into download mode then plug USB in. Worked fine for me.
Cheers
Everytime I flash the stock ROM, I will have bootloop. I get into stock recovery mode, do a factory wipe and reboot. My phone boots up normally after that.

Why are you flashing the stock ROM? Upgrading? If you are flashing a different ROM or different Android version, your /data won't work with the new version. If you are flashing to a similar version, try only wiping the cache and dalvik cache.

I'm a flash addict. I will try new ROMs. I case anything went wrong, this will by my rescue step. Last week, my phone's external speaker malfunctioned. So I need to get back to stock. I need to unroot and flash stock firmware. I encountered boothloop. So, do a factory wipe and reboot. All was OK.

what type of speaker malfunctioning you got? I am facing some problem with audio/video apps. all audio/video related apps(even call ringtones) not running smoothly half of the time. I have tried many roms. Now i flashed stock firmware via odin and still have same issue.
I have not done any data/cache wipe before odin flash. Is full data/cache wipe is required for stock firmware via odin. OR any other solution you can suggest.

My phone was under warranty. So I reset the binary counter and reflashed stock ROM. Send it to Service Centre. They said my speaker was spoilt. So they replaced the speakers
I ODIN'd back to stock from the Avatar Rom. I ran the update file twice to get into CWM recovery. I did the Factory Wipe, Wipe Data, & Wipe Dalvik Cache process. Loaded cm-10-20120823.1414-UNOFFICIAL-vibrantmtd which I had on my phone once before and when starting it said my IMEI was different. No biggie, went back to stock. Tested the phone, IMEI was back to normal.
I then did the update to root only, booted the phone, downloaded Titanium Backup Pro since I've been able to restore my IMEI before while using it, tried to use it and was told I wasn't rooted.
I then downloaded and renamed recovery-clockwork-2.5.1.2-vibrant to update.zip. I ran the update file twice to get into CWM recovery. I did the Factory Wipe, Wipe Data, & Wipe Dalvik Cache process. Loaded cm-10-20120823.1414-UNOFFICIAL-vibrantmtd again on my phone and when starting it said my IMEI was different.
Can someone tell me what is going wrong? Recovery also seems to be reverting back to stock recovery when I go into it.
Used SOC. Loaded RemICS, no IMEI change occured. FIXED!!!!!!
Could it be that I need to first install CM7 before the CM10? That wouldn't explain the phone reverting back to stock recovery though.
before this happened I'm on SLX v24 and TWRP 2.7.1, everything normal and no error. Then I want to try the MIUI v7 5.10.8. I follow the instructions in xda, I flashed newest TWRP 2.8.7 rev1 (inside the zip there's update-binary-f2fs), reboot again to TWRP and flashed MIUI, and reboot to MIUI, then I noticed that there's no baseband and IMEI, then I restore IMEI from my backup with mobileuncle, reboot it, and still unknown. I try to change modem, reboot it, and still unknown. I cant edit the cds radio. I already tried deleted the nvram folder, reboot it and still unknown. Then I tried to flashed it to stock rom with flashtool hoping it restored to normal, but still the baseband and IMEI unknown.
can anyone help me??

Hi. Try this, but no garanties, because you could corrupted the NVRAM:
1. Download this recovery openrecovery-twrp-2.8.4.0rev2-p780row.zip from here; NOT OPTIONAL, ONLY THAT RECOVERY.
2. put it on the sd card .
3. Reboot in recovery and flash openrecovery-twrp-2.8.4.0rev2-p780row.zip.
4. reboot in recovery again.
5. do a full wipe except sd card
6. Reboot in system and tell me if your imei is back.
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
My phone was dead due to unknown reason. It was very slow for last couple of days, so I reboot the phone into recovery and then wipe cache and dalvik. After the wipe I reboot the phone but it stuck on Samsung logo. So I tried different unsuccessful methods like, flash stock ROM, etc...
After flashing the stock ROM, rebooted the phone into recovery for factory reset, then only I noticed the error E:failed to mount /efs (Invalid argument).

I had this exact same problem all week.
There are a few steps you need to take before you can get your phone back to normal.
Step 1. DO NOT wipe the efs. Doing so will wipe your IMEI and serial number therefore never letting your phone connect to a cellular network again.
Step 2. Flash TWRP with ODIN and backup your efs using TWRP (make sure to keep this backup on your PC)
Step 3. Get the zerolte PIT file and the BTU stock ROM (Flashing my original stock rom didnt fix the issue so I used BTU and it fixed it)
Step 4. Flash the PIT file using ODIN and wait for your phone to restart. Then enter download mode again and flash the BTU stock rom
Step 5. Go back into ODIN and flash TWRP again, then make a backup of your efs again.
Step 6. Plug your device back into your PC and put your backed up efs from step 2 into the new backup and overwrite the files
Step 7. Restore the backup in TWRP and restart your phone
If your phone boots wait a little while and the carrier selection menu may show up. At this point you can leave your phone on that ROM and wait for Samsungs updates.
Common asked questions:
My phone fails at sboot.bin. You either havent flashed the PIT file or your phones bootloader has been updated to a newer bootloader. Try flashing just the modem.bin file from the tar file and seeing if that fixes your issue.
I've wiped my efs partition. In this event you need to go to a repair shop and have them write you a new efs. Once a efs is wiped your IMEI and serial number are irreversibly gone.
My phone fails at hidden.img. Try flashing again if its not working flash a new PIT file and try again.
The file name of my firmware: G925FXXU5DQA7_G925FBTU5DQA2_G925FXXU5DPL3_HOME.tar.md5
Android version: 6.0.1
CSC: BTU
Hope this helps you fix your device
