Hello.
I've got really strange issue, so i'm currently using s5 port rom.
It's is really sluggish so i wanted to move to some aosp based rom. The problem is whenever i flash a new rom my modem/ baseband become unknown and i can't see my efs partition. Restoring proper backups from many tools don't help. I also tried to flash modems but no succed (normal modems and zuluman modded on by twrp and touch cwm (not philz one)). It stills stays as unknown. Once when i formatted whole efs partition it gave me normal modem version but as soon i restored efs, modem became unknown. When i go back to s5 port rom everything is working as should (is it because aroma installer?).
Is it some kind of bug or i bricked my phone in weird way?
Thanks in advance
When flashing roms you must flash back to stock each time to make sure the device is working as it should. It ensures that any problems are related to whatever you're doing.
I have had circumstances where I have flashed a stock firmware, let the phone boot, switched off, flashed a custom rom, booted the phone, run maps and location was miles away with no way to change it.
Flashed back to stock twice with a factory reset in between and let the phone boot, location worked fine again.
The point I'm trying to make is that bugs can be inherent. Just because you flash another rom it doesn't mean everything is fixed that was previously broken. Only stock roms can do that. Something I've noticed with flashing stock firmware is that on the first flash it seems to only replace what is different from stock. On the second flash it replaces EVERYTHING. I don't know if this is actual or just my imagination but it seems the case for my I9300.
Once you have a stock working device make a backup of your modem and efs. Flash whatever you need and if you have issues then try restoration of the backup you made..
You can never make enough backups!.

I got an issue...
Am running Sensation Rom (info is in sig)
I try to flash any new kernel and when my phone reboots, my phone can't see the IMEA (and obviously all the issues that come with no IME)... so i then do the whole nandroid restore and everything is good again.
I try restoring my EFS to get my IMEA back but it doesn't work either.
Sucks cause I was hoping to update and try different kernels!! Now I got no choice but to stick with stock!!
Any help on this issue would be fantastic!!!
You can easily install new kernels from the phone itself using kTool from market. Have You tried this ?
Btw. I don't understant completly - have you recovered and You phone, imei etc. is all ok now ? You stated that EFS backup cannot be restored.
This happened to me the first time I used a jig. Reset the download counter but upon boot found the IMEI was unknown and the modem/baseband was also unknown.
Took a punt & reflashed the modem thru Odin & this fixed it, given the modem wasn't showing up I put 2 & 2 together & tried this first. Not sure if this will fix your problem but surely couldn't hurt ?
Also, running my current rom/kernel combo, occasionally immediately after a reboot (say for 30 seconds or so after the phone has seemingly finished loading everything), my IMEI/modem is also unknown. This seems to sort itself out so pretty quickly so is probably a case of the boot process not being complete.
I really wanted to work this out myself but my time is very limited, I do not have access to a PC so don't want to risk bricking, and I've already spent many hours searching answers and downloading files. I need a working phone ASAP and it's not easy finding a spare in my current situation.
My phone died (battery) while active as hotspot. I replaced battery and now it won't detect ANY sim card (sim cards verified to work). Upon attempting to access mobile network settings: "Insert sim card to access network services".
Also, I'm not sure if it's related or not, but IMEI number is "unknown".
I'm really hoping it's a software/firmware corruption issue that I can fix.
I have tried the following:
Replacing sim
Fight mode
Restarting
Combinations of the above 3
Wiping SD card
Factory reset
Reflashing CF-root kernel via CWM (I think it worked but reboots before I can read log).
Now I want to try flashing a custom ROM. I have CWM installed and I was going to install CyanogenMod. I am aware of how to do this, but...
- I read that attempting to flash a JB ROM over a gingerbread kernel can cause an issue and that I may need to flash a JB kernel before installing cyanogenmod. Is this true? And if so, where can I find out what kernel to flash. I've seen lists, but I see all these numbers and names which don't really mean anything to me. Is there a stock JB kernel that would be suitable, or is any KB kernel fine?
- Does installing a custom ROM like CM not flash it's own custom kernel? Because I don't understand why having a gingerbread kernel should potentially cause issues.
- Is there anything that installing a custom ROM like CM doesn't flash (apart from bootloader)?
- Should I just flash a stable gingerbread CM ROM instead?
I appreciate any info
Cheers

I also flashed modem. Problem persists.
Ok mate u said u want flash cm10.2 looks u got cwm ok then do this download ur cm10.2 rom copy to sd card then download latest kernel 9.39 from this link
http://dorimanx.shine.sk/
Copy tu ur sd
After that boot into cwm find kernrl u downloaded dorimanx9.39 and flash , when u do that reboot cwm and start flashing ur cm10.2 and dnt forget about gapps
Now u can enjoy ur cm10.2 .
Omt if u wanna stay with stock cm kernel just reboot but if u wanna have most adwenced kernel for sgs2 after flashing cm flash again dorimanx 9.39 a to solve ur missing imei chose one of this modems from this link http://forum.xda-developers.com/showthread.php?p=31416701 and flash exacly the same like rom,kernel a if u got crap reception flash another modem.

At op do you have a efs bk up?

Flashing anything without a PC nearby is lunacy/asking for trouble. If something goes even slightly wrong, you won't be fixing it without one.

The problem is the unknown IMEI because the phone gets identified my this unique number. If its lost, SIM-Cards won't work. If you made an EFS Backup, it should be easy to recover the IMEI. But if you didn't...it will be nearly impossible.

Thanks for the info. However I have flashed multiple modems and phone is still nit detecting sim. IMEI still missing.

I'd never heard of backing up the EFS before yesterday, so unfortunately I don't have one with IMEI. I think I have a nandroid backup at home somewhere, would this have a backup of the EFS/IMEI?
If I had it written down, would that allow recovery of EMEI?
Some roms bk up to efs folder so looking in to your sd card you may have one. Flash the nand if not it may restore it. May not though. Worth trying. Have you tried to flash gb firmware with odin as this has for some got it bk.

If I have a backup it will be on my PC or a HDD on the other side of the planet. But I will indeed look for it when I can. I'm fairly confident I would've done a full backup before I flashed a CF root kernel via Odin when I originally rooted the phone.
And no I haven't tried to flash gingerbread firmware via Odin. I don't have access to a PC. But I did flash the CF root kernel via CWM.
Your gonna need to look and hope your have mate or service center job. Local phone shop could prob do it to.

Fixed. Thanks stopro.
The phone was deteriorating. Apart from not detecting sim cards, it somehow lost su access. Even though I would allow access it would fail (issue with system/xbin/su). I couldn't even connect to WiFi anymore.
Flashed Dorimanx kernel 9.39
Flashed latest CM 10.2 nightly
Flashed GApps
Flashed modem
Wiped cache and Dalvik cache 2x each
Did a data wipe/factory reset
Booted
All working fine. IMEI number is displayed correctly. WiFi connected immediately (could not successfully obtain IP address before). I had to re unlock my phone to use a different carrier sim (I unlocked it before leaving Australia, but that flashing must've relocked it). Now it is connected to 3G with which I am posting this reply.
Not really digging this JB style, but hopefully I'll get used to it. Happy I've got phone all working properly though.
Dear,
I installed 4.4 RC1 PA, per the instructions, however I'm stuck in bootloop. Then I tried to go back to an earlier version, of course with a suitable kernel, but still the same. Then I installed the stock rom 4.1.2, and again repeated bootloop. Finally install the stock ICS, the system is booted, but I do not have a GSM network. Once again I try to install custom, happens to bootloop. Works only stock ICS but without GSM network. Do something was wrong?
Thanks in advance!
I guess your EFS partition got all messed up while flashing.No baseband,no serial,no imei,no signal and so on.Have you made any backup of it?
This EFS thing is tricky.Search around here to get an idea about this.

What you think, is this possible way to fix? I'll try this. http://www.digitalreborn.com/fix-samsung-galaxy-unable-mount-efs/
So I assume you have a backup.There are plenty of tools for restoring it,like the EFS Professional or kTool.If your backup is in either img or tar format,easy way could be restoring it via philz kernel's advanced recovery(if you are using stock jb or ics).
hi i was wondering if you guys can help me, i have an efs backup,but i cant seem to be able to restore my imei,i tried Ktool,efs professional,nothing seems to work,i should mention that the efs backup was from a Samsung 4.1.2 stock now my phone is on CM11
thanks
I dont know if cm base and sam base modems are same but if they are:
Firs option: many custom roms come without modems to prevent the country issues so assume that your old modem is still installed you can try to install a new cm modem or like i said if they are same a new version sammy modem.
Second option: go back to stock 4.1.2 and see if your imei is still intact. If not restore your 4.1.2 imei see if it is back. If It is back first try to upgrade official 4.3 via odin then install cm 11 with wipe...

thanks for replying, I flashed a patched modem and kernal from a different post, but I got boot loop,so I restored a backup that I made before flashing from recovery,and for some reason every thing is OK now maybe restoring is the silotion.
BTW the backup was made after I restored my efs.hop that helps someone.
In a way you helped me, thank you.

You got bootloop because that modem and kernel are for sammy 4.3 and yours is CM. The backup you restored, is it nandroid backup and is it 4.1.2 ?

no, the backup i restored was from CM 11,thats what surprised me i made the backup in philz touch right before i flashed the patched modem and the kernel to try and solve the imei issue, it was a normal backup (the one where you back every thing),meaning the imei problem was still there,but it was after i tried to restore my original EFS.
so here is what i did in steps
-got corrupted imei on CM 11
-tried to restore with my EFS backup that i made while i was on sammy 4.1.2 using different apps and methods didn't work
-made a full backup using philz before flashing a new modem as suggested
-got boot loop after flashing a new modem
-restored the backup i made before flashing the modem and for some reason my imei was back

I think the reason you got your imei back is the modem you installed with the kernel. So here is what i think happened. You had bootloop so restore got your old kernel back and modem stayed intact. Shortly if you had just installed a new modem from the begenning you would have sold your problem i always say best way to learn is try and fail. i am happy that you have your phone back [emoji106]
I also suggest you to replace the modem with an unpatched clean one. You can have network problem in the future...
Hey,
My friend was running a flawless custom rom on his s3. Suddenly, it turns off by itself and the phone is then stuck on boot logo.
1. I tried to factory reset with no luck.
2. I tried to install stock 4.3 with no luck.
3. I tried to install 4.1.2. The phone booted but with no recovery. Then i noticed that imei changed to *0049 and i'm not registered on network (even though it was working well on the custom rom).
4. I tried to upgrade to 4.3, i got succeeded but recovery didnt install.
5. I tried to install the custom rom again but no luck.
6. I tried all patches of modems and kernels and ariza. All Failed.
7. I also tried EFS backup/restore and Failed.
My only concern is to know what made this issue appear all by itself ?? Because i guess we should take it to a mobile repair shop.
One last thing to say is that every time i try to install a software, available space gets low, and even if i delete some files from internal storage the storage wont free up.
Thank you !
get stock 4.3 fom and flash it via Odin (wipe everything before flash). Then flash recovery via odin. then backup efs. then flash custom roms.
downgrade from 4.3 to 4.1.x causes efs to become corrupted
Seems like a corrupt nand. Was it rooted previously when it died the first time?.
Going from 4.3 to 4.1.2 will cause the imei to be lost as the efs encryption changed at 4.3. You cannot go back.
If the phone has a custom rom on it try an official cwm recovery, if not or it doesn't work then proceed to the following:
If you can get the phone into download mode try flashing the stock firmware twice or thrice with a factory reset in between each flash. Do not allow the phone to boot into the os!!. If it attempts to boot to OS after the blue pass in odin then pull the battery out immediately and boot to recovery or download mode respective of what you are doing at the time, resetting or flashing.
If that fails you can then call it a dead phone.

Wow these are new solutions to me..
I really thank you guys and i'll look forward into trying them in any upcoming problems.
Thank you so much for sharing your knowledge
And just to mention, yes the phone was rooted when it went bricked suddenly.
I'd try to flash an official cwm and if it takes then flash back to stock twice with a reset, reroot and leave it as that. Custom roms aren't worth the paper they're written on.
In addition to downgrading from 4.3 to an earlier version, but forgot at the time of writing, you can downgrade but you need an efs backup from the time it was at 4.1.2, which has to be restored but I'm not sure of the process. I couldn't tell you if it has to be restored before flashing, after or both.
Not a lot of people have an efs backup from 4.1.2. I do, but then my phone hasn't acted wierd yet. Sods law.
Kies 2 (not kies 3) can restore the phone but only if it was in original condition. You can try the emergency recovery routine but don't hold your breath.

You're right.. Efs is the only part most of us miss !!
I wrote all of the steps you said in order.. So that if any problem occur ill deal with it based on your info.
Btw do you suggest using KK TW 4.4.4 by back-to-n00t ? Or this wont be considered as a kind of official firmware ?
