My Samsung S2 worked for about half a year perfectly with the leomar revolution rom.
Yesterday it stoped working. The Sim Card is no longer accessable and the baseband displays base band unknown.
So i reverted to the backups i created and it was no solution.
I tried cyagnomode and it detected the card everything, but i think in the wrong baseband version because it could not unlock the sim card (it took ages and there was no progress).
I swaped back to my original system and tried it again and also here i got no solution.
My Provider is O2 Germany.
I had the unbranded S2.
The original pda version was XWKE7
I hope you can help me.
I don't want to have an expensive mp3 player!
Type *#06# into your phone, does it display your imei number? If not did you make a backup of your efs folder when you started flashing custom roms?

Try this thread. Assuming you don't have a backup of your EFS, that is.
So I was trying some new roms (CM11, temasek, etc) today and I got an error when flashing an old 4.1 samsung rom (I was on 4.3 official yesterday).
Now my SIM card is not recognized. It says "only emergency calls" and nothing else. I don't have cell signal at all.
I tried taking out the SIM and putting it inside again and factory reset in CM. I also tried flashing again the 4.3 samsung unlocked rom.
I'm downloading right now the 4.3 official rom from Vodafone (my carrier), in hopes that will fixed it with ODIN, but just to be sure I'll ask if anyone knows how to fix this issue.
Thanks!
Hundreds of identical posts, search and read before starting new threads.
If flashing the stock 4.3 rom with odin doesn't work then you'll need the backup you made of your efs folder.
Hello everyone,
First of all i want to thank you for all this guides that i was trying to use here
So here's my story.
I got Samsung Galaxy S3 I9300 with bootloop issue so i decide to fix this by myself.
I was trying to install fimware using KIES but i doesn't fix my issue.
Then i was trying to search for right rom on several websites.
The right one and only working one was 4.0.4 with orange brand logo.
So i was excited that its finally working
Then i realize that my imei is null and my sim card is not working.
So i was trying to restore EFS using several tools and methods.
Finally i got it default IMEI 0049 but it was still not working.
My phone is not qualcomm based model so i cannot use nv item reader writer as it's required to edit IMEI
Even after applying phonutil patch my device is not being recognize as Qualcomm one.(because it's not)
So i was still looking for another way to change my imei manually as i have my original one on the box and under battery.
Finally I realized that i cannot make even Emergency calls it comes with message Out of service area.
So i was trying to apply few modem and radio updates to my phone but none of them are helping.
Anyone have similiar issue?
I have another Galaxy S3 that is working can i copy imei or whole system to my not working phone?
I know that after that i cannot use other device, but thats ok if its possible.

Have you tried patched modem and kernel? Did you read the guides on xda >> http://forum.xda-developers.com/galaxy-s3/general/ref-imei-efs-stuff-i9300-including-t2393289 << and no you cannot copy imei from another phone.

I tried everything from this guide.
Regarding patch:
4.0.4-I9300BVALE4 firmware is the only one working on my Samsung
Patched modem and kernel that i found and try it are XXUGMK6.
Maybe they are different one or dedicated to my firmware

The reason you can't make calls is because at some point your phone software was on 4.3 this means your efs as changed to efs v2. Now because your current firmware is at 4.0.4 then your efs can't read this because 4.0.4 is efs v1. So you need to get a 4.3 stock rom onto your phone (I know you said only 4.0.4 works) but what are you using install firmware are you using Odin? If so what errors are you getting installing with Odin.
The patched modems and kernels are for 4.3 so they won't work on 4.0.4 or any other apart from 4.3
I was trying so many of them but its always ends with samsung logo loop it doesn' matter if i'm
do things like wipe cache, factory settings etc everytime its not working.
Even on 4.0.4 only this one rom is working.
Im always using ODIN, with KIES its always ends with samsung logo loop.

Ok a couple of things you could try (if you haven't already) I presume you have a custom recovery? Try flashing a custom stock 4.3 with recovery I suggest this >> http://forum.xda-developers.com/galaxy-s3/general/rom-sammys-stock-deodexed-rooted-t2585670 << This is as close to stock as possible but can be flashed with a custom recovery like Cwm,PhilZ,Twrp etc. You will also need to flash a 4.3 modem for this which is included in the thread. If the modem in the thread does not give you a signal (presuming the rom boots ) then keep the same custom rom but flash a patched modem and kernel on top with your custom recovery.
Don't forget to factory reset after flashing!
If none of that works you can always try the rescue firmware here >> http://forum.xda-developers.com/showpost.php?p=30087735&postcount=6 << obviously flash the 4.3 one. Hope that helps
Thank you very much for your help i will try this and let know here if it's working

So it's me again.
I have good news and bad news.
So i was able to install both of firmware with success.
After applying patched modem everything was still working.
But when im calling 112 for example im still having "out of service area" and my imei is still 004999...
So issue is still exist.
I can discover any network when i choose network its even says"registred on network" but then if im trying to choose some number im having error message that im not registred or if emergency call "out of service area".
Any ideas what still can i try ?
hey guys!
I have samsung galaxy s2 gt-I9100. Whenever I install a custom rom, everythings works fine but i am not able to use mobile network and i received "Error while searching for networks" when I go to settings>>Mobile networks>>network operators. The IMIE number is fine.
I have tried many roms including:
--cm-10.1.3-i9100
--cm-11-20140804-SNAPSHOT-M9-i9100
--pa_i9100-4.42-20140708
--pa_i9100-4.45-20140729
--Slim-i9100-4.4.4.build.9.0-OFFICIAL-8301
The last rom which worked fine was RootBox-JB-i9100-V4.0. All roms released after this rom have this issue.
I have searched for issue on google and tried various solutions but so far no success.
Please Help!
And can you guys suggest me any rom which is not based on CM?
Go to settings-->about phone and look for "Baseband version"
If it says "unknown" or similar you may need to reflash the modem before you flash the rom.
Or even worse you might need to do a reboot (it actually worked once).
Also do emergency calls work? If yes then it might be a problem with your sim card or you contract (or just bad luck).

The Baseband version is visible and a valid one. Also my sim works on stock rom or any other phone.
SInce I have no idea what the cause could be, here are some random things to try out, of which one might work:
-make sure you're not in airplane mode
-do a full complete wipe
-try a different sim (and see if it works)
-make sure the sim is not upside down
-fully shutdown the phone (e.g remove battery for a day [maybe not that long])
-clean contacts between sim and phone (how? no idea)
-try (even-) more roms (if there are any left)
-test a few kernels
-maybe look through the logcat (if it actaully outputs something worthwhile)
As you can see none of these "soloutions" are based on.....uhmm....anything(?). But at least....if none of them work, you know what not to do.

Perhaps you could flash back to stock rom then flash custom rom again, that way all modem files and network related files can be fixed/re-installed. By any chance have you tried changing modems? It might not help you but it's a suggestion.
I have null imei after update. LineageOS 14.1 for i9300 network services are not running. Is there a solution for this release and post? It is possible to make a development like "Zuluman, ariza", can you do this? I want so much. The only solution to this problem. I live in Turkey. I bought a device IMEI changed from abroad. These problems were solved for 4.4 and before, "Zuluman and Ariza". However, nothing was done for the new releases. Help, thank you
You need a patched modem.
Beamed in by telepathy.
I have it for 4.4. But not for later versions. Required for later versions. I want to install 7.1. Required for 7.1.
I recommend you flash a stock rom and see if the problem still exists.
Lineage os is frequently updated and it is very likely that the build you have has issues with wifi.
Beamed in by telepathy.
I tried to install but I get Error: 7 in the TWRP.
Tried with 3.0.2.2 and 3.1.0
Anyone with this problem too?
I have no cellular data on my Galaxy S3 i9300, with Lineage, though it works fine with Archidroid, which I have installed since. Cell Data worked briefly with Lineage, but now not at all. I believe it might have been triggered by turning off wifi, but not sure. Tried a complete wipe of all caches, data, system, etc. plus a reformat of internal before clean installing lineage-14.1-201727-nightly with GAPPS pico. My IMEI is still intact, so that doesn't seem to be the issue, as cited above.
I have the same problem unfortunately. I just wiped my old stock android from my Galaxy S III and installed Lineage OS 14.1. The installation seems to work well, except that my Sim card is not recognised. When I check "Baseband version" in Settings/Phone Status it tells me "Unknown". I assume it has something to do with the modem driver. Does anybody know where to get the right modem driver?
I tried googling for a modem driver and installing it with heimdall. But then my phone didn't start anymore and I had to reinstall Lineage OS...
Reinstall the stock firmware via odin..

Do you know where I can find such a stock version? Unfortunately I made a mistake with the recovery backup...
Look at sammobile.com or updato.com for the latest stock ROM.
Thank you! Unfortunately this didn't work... I downloaded the firmware (for Cyprus because the phone was bought in Cyprus) and used Odin to install it but now when I try to turn on the phone it just shows the boot screen (saying Samsung Galaxy S 3) and then goes black... I'm not sure what I am doing wrong here. Perhaps I didn't choose the right firmware, do you know how to find out what exact firmware I should download? I got the phone used, so I am not 100% sure it was bought in Cyprus, perhaps UK but it was bought without a network provider.

Is there anywhere I can get a clean unlocked stock rom for the U.S. GT-I9300? I lost mine and had to use a T-Mobile rom from elsewhere. Why is this, or a rom from any U.S. carrier nonexistent on the lists? Thanks!
The gt-I9300 was never sold in the USA so there was never a stock USA rom. The T-Mobile s3 was the sgh-t999.
Is the phone shown as the get-I9300 in download mode?

That statement doesn't make sense to me. I live in California, USA and bought it as an unlocked, no carrier, International GT-I9300 from BestBuy. It never had a carrier logo associated with it originally, but since I had to replace the original rom, it now includes a T-Mobile splash after the Samsung S3 splash.
Yes, it states that its a GT-I9300 in Download mode.
The gt-i9300 international was never sold by T-Mobile USA as it doesn't support LTE in the USA:https://www.gsmarena.com/samsung_i9300_galaxy_s_iii-4238.php.
This is the T-Mobile USA s3: https://www.gsmarena.com/samsung_galaxy_s_iii_t999-4804.php

Thanks, but I'm not looking for a T-Mobile USA stock rom. I'm looking for the GT-I9300 USA International, Unlocked stock rom that originally came with my USA purchased GT-I9300. From what I understand, local service providers have access to it, but Samsung won't post it publicly, like the others. Hoping someone may have a link to a copy they've found or backed-up from their own USA GT-I9300.
I have never heard of or come across a USA international rom for the gt-i9300.

I brush three times I9300ZCUBML1, or useless.
lineage-14.1-20180124-nightly-i9300-signed.zip
And brush the rom can not use 5Ghz wifi, but when using the signal I9300ZCUBML1 than my nexus6p weaker, simply can not be used in a stable, so no problem.
Where did you get the ML1 ROM? I don't see it on sammobile.com: https://www.sammobile.com/firmwares/galaxy-s-/GT-I9300/. Since the ROM ends in ML1, it could be a 4.1 ROM. Thanks.
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
