No Signal, Can't Flash Any Firmware ! - Galaxy S II Q&A, Help & Troubleshooting

Hello, I own Galaxy S2, after I tried to update firmware to JPKI1 ( Downloaded from samfirmware), the flash went ok but after that, I noticed the Signal is gone, IMEI and I CANT do any reflashing either to stock or custom, I used ODIN to do the flashing procedure, each time I flash a Firmware nothing happens the old (JPKI1) version still there, I'm confused what to do now DIY or Service center?.
Regards.

sounds like you may have nuked your efs folder.
If you ment to write I noticed the Signal is gone and the IMEI
Hopefully you have a backup

Can you flash a new rom & rooted kernel via odin
then look to see what you have in /efs
If you have any backup files under /efs, say /efs/_nvdata.bak you may be in luck (I was)

Well, I tried to flash another kernel and another rom but the weird thing is after finishing the flashing, nothing happens at all, the old version is there, even if i do a data wipe, the data doesn't wipe at all, every thing is still the same, thanks for the reply.
BTW: I haven't found anything in efs folder.

EFS corruption? Baseband and IMEI Unknown

Currently on Checkrom XWLA4 2.3.6 with Speedmod kernal.
Last night I performed a Titanium backup and a Nandroid backup in preparation for an upgrade. I had previously performed an EFS backup sometime back. I didn't perform the upgrade, just completed some backups. Anyways over night something seems to have gone wrong with my phone. I wake up to find that it's showing there's no SIM card detected and then when I checked baseband version and IMEI both are showing unknown as well as a bunch of other fields.
I've tried a number of ways to restore the EFS folder. I've tried GSII_Repair, EFS Pro 1.9, kTool, and a couple of manual methods. All of which give the same result.
Some strange things that I noticed, I have an EFS folder inside of an EFS folder. The /efs folder seems to have less files then the /efs/efs folder. Also /efs/efs folder was the fold that had the .nv_data.bak and .nv_data.bak.md5. Not sure if its suppose to be that way.
Wondering what the best way to try to get my phone up and running would be.
Thanks,
Lu.

The problem:
(a) You performed nandroid backup in CWM recovery while your phone was connected to the charger. This is a known bug of almost all versions of CWM recovery.
(b) Baseband missing means that your Modem was wiped off which happened as a result of the bug in (a.)
Further Explanation
a. this has nothing to do with your /efs folder
b. If baseband is missing then the phone can never read your IMEI, hence no network
Possible Solution
a. Download Modem (CWM zip format) of your choice. If you already have a modem then, skip to next step
b. Disconnect your phone from the charger
c. Boot to CWM recovery
d. Flash modem.zip you downloaded
e. Reboot phone
check your phone info after reboot (give your phone about 5 minutes to settle down), your IMEI, network etc should be back now
good luck

it was definitely plugged into my usb port charging at the time. just tried what you recommended and still the same issue. i wouldn't be surprised if everything that i tried today with the efs folder made it worse.
any recommendations? would it help if i tried a fresh install of xwla4 (2.3.6) or something newer like xwlpg (4.0.3)?
really need to get this fixed. any info or step-by-steps are greatly appreciated.
thanks.

You shouldn't have messed with your efs partition after the issue came up. it's suppose to be the last solution and not the first one.
ok.
try this:
-Remove your SIM.
-Reboot to CWM recovery
-Flash modem
-wipe cache partition
-wipe dalvik cache
-reboot phone
-Allow phone to stay for 5 mins.
-check your phone info, check IMEI
if both are back fine, just reinsert your sim and continue normal life.
let me know what happens

Not sure what happened or how this happened but while I was retrieving the information from the About Phone screen the baseband was showing unknown and then once I glanced back down to get some more info, it just appeared and within another few seconds I got my IMEI and cellular services started working!
Thank you very much kind sir! Greatly appreciated!

When you have this kind of problem, messing with /efs should always be the last solution and not the first one.

in your own case, where baseband and imei was missing, changing anything in the efs comes last because, if it's other thing related, flashing modem , firmware and things like that should fix the problem.
Then the last thing is messing with /efs partition.
Why, because, efs partition is not touched during flashing of ROM/firmware. It contains sensitive files, and should only be modified as last resort.

I did a back up on sd and pc. Before. I had only flashed from rr 2.6.1 rom to a jb rr rom after a few days of not changing any thing it came up network locked enter code etc. Whilst out driving so nothing I changed iko. Now it still changes imei but I have a stored working backup so I jus restore that and reboot. Would a modem and rom have to be compatible? I've never changed my modem do I need too and is it flashable? thanks
I only have these problems cos standard isn't different..

GII_repair (app), you must backup your efs first,
Or manually repair your efs folder by following the tutorial here: forum.xda-developers.com/showthread.php?t=1264021

[SOLVED]Service problems after installing costum ROM

After having S3 for some months, I decided to update it to 4.3.
So I searched online and saw some tutorials how to root and install costum ROMs.
I read few tutorials to be sure how to do that and after all went good and the ROM installed, One problem has rised: NO SIGNAL!
so I wiped all and installed a ROM STOCK.
After that the signal came back "half way". It's showing signal bars but I can't call to anyone, even after calling to my provider...
I just don't know what to do. Please help

well these tutorial you've read were either very bad or you haven't read them correctly, because probably you missed the important step of the efs backup. see therefor the stickies thread or the thousands of similiar questions here in the q&a.

That is your backup flash with odin
( When you flashed a custom rom it probably backed up your efs some roms backup by default)
I would just backup your efs you have at the moment just in case you have problems flashing. You will then be able to return to how your efs is now even though it is not fully working..
Or try this app >> https://play.google.com/store/apps/details?id=net.hellcat.droiddev.ktool <<
The phone has to bee rotted to use ktool?
I also understand from the link you did about the EFS that there are two types of base bands and if I have an efs backup that I did on V1 baseband so I can't restore it on a v2 baseband, so my conclusion is to get back to 4.1.2... correct me if I am wrong

good that you found efs backup
yes you need root. or you use the recovery philz touch to restore your efs (then you don't need root, but a custom recovery).
well samsung roms based on 4.3 need efs v2, so you have to go back to 4.1.2 to restore your efs v1 backup.
if everything is working again, I would suggest you to use oding to upgrade to 4.3, because then everything should be updated correctly (but keep your efs backup, and make another one, just to be sure)
then you can try out again custom roms based on sammy 4.3
So what is the best option to restore it?
Because before I tried (while 4.3 stock rom was installed) the flash it with Odin but Odin always crashed when I was uploading it to Odin.
With kTool I tried before but when I am clicking on the button it says that it restored but he didn't asked for directory, when do I need to put it?
The same story with phliz, I also tried with this and he don't asks for directory, only asking whan the ending if the file-tar to bin...

Where is this folder located? I can't find it
and does it for xTool and phliz recovery destinations for teaking the recovery from?
Edit:
I found the /efs. I dind't know that I need to use root explorer...
I exchanged the files with my back up and suddenly instead of 0049 IMEI I got 0000 IMEI.
I tired also to flash a modem and also didin't work...

Hmm... try installing another EFSv2 modem, then do the /efs copying part again.
Suddenly after so restarts, the IMEI got back
But... The SN now is 0000000000
You'll need to correct the permissions of the files you've copied. Try searching for someone who already did this and duplicate what they did.

Ok,
I tried something new. I flashed a new modem, backed up a full backup and then installed a costum rom 4.3.
the IMEI GOT BACK! And even the SERIAL NUMBER!
But I think the serial number is not good because he has 16 or 17 (I don't remember) digits (numbers and letters).
But still i have signal bars but can't make or receive calls he says: "No registered on network"
For the finalle, I tried ARIZA patch but he Is stuck on 0%...
here I stopped, I really don't know what to do.
Don't use the Ariza patch once you've got your IMEI and SN back. Maybe try flashing a new stock version of Android with a EFSv2 baseband so as to not go through the copying fiasco.

hey there everybody
i have a serious issue and i think i could use your help
well previously i was on stock rom 4.2.2 on my I9300, then i flashing 4.3 manually using odin and downloaded the rom from sammobile anyhow since i flashed that firmware i can no longer access anything on my sim card, meaning i cant call or receive any call from anyone, it keeps saying no registered on network, then i thought it could be the rom or something, i tried pa rom and cm official latest builds but in vain, the same issue, i tried changing the sim card but the same, issue not resolved....how can i solve this prob, i wish it is just a software issue not a hardware
i also tried following this link, i thought it would help somehow, but in vain as well, now i have no idea what to do to solve this issue, tried reflashing another stock rom which is probably more appropriate than the old one, but also it didnt work, so now i have no idea what to do, i just need urgent help please, thanks a lot in advance

dude there are many patches and modems, which one shall i be flashing? there are 3, patched kernel, patched modem, and this one (Patched_I9300XXUGMK6_Kernel_StockRepacked.zip) which one then?
pardon me for im new to this patch and modem, so i have no idea according to what i have to choose
btw dude, i just noticed that there is another stock 4.3 rom for my country, would flashing that stock firmware be of any good and solve the issue?

Hi sorry I have been away from computer i'm glad to see you got it working You will always need to use a patched modem and kernel the only way to return to normal would have been to backup your efs before it got changed. As for backing up your efs you can back it up with PhilZ recovery I'm not sure about twrp iv'e not used it for a while. There are are a few apps/programs that can back it up also just do a search on xda. But remember you will always need to use the patched modem/kernel if you change roms.

Because when you flashed from 4.2 to 4.3 your efs got changed from efs v1 to efs v2 and in the process it got slightly corrupt so it was unable to read your modem ( This happens some times and you where unlucky) .This is a lesson for all people to make sure they backup the efs before flashing roms ( Especially the very first rom that they flash) it is the very first thing you should ever do.
IMEI changed after flashing to 4.3 jellybean GT-I9300

Because when you flashed from 4.2 to 4.3 your efs got changed from efs v1 to efs v2 and in the process it got slightly corrupt so it was unable to read your modem ( This happens some times and you where unlucky) .This is a lesson for all people to make sure they backup the efs before flashing roms ( Especially the very first rom that they flash) it is the very first thing you should ever do.

hi there, I've just been reading, and I have the same problem MY IMEI number changed to a generic *0049*. I just clicked on the link but can I ask which one is the kernel patch and which one is the modem patch do I need to download?

The one that says kernel is kernel patch and the one that says modem is the modem patch lol Try the mk6 modem and the mk6 kernel patch flash them in custom recovery with 4.3 rom. If you get bootloop reboot into recovery and factory reset. Please note this is not guaranteed to fix all imei issues but does help in some cases.

Is there a possibility that there's a way that I could just wipe my entire phone clean of all partition and data and start a fresh firmware update?, if so how can I do that, as I have a corrupted file then I think if it can be done it might just work a fresh firmware flash on a clean system??

Read here >> http://forum.xda-developers.com/galaxy-s3/general/ref-imei-efs-stuff-i9300-including-t2393289 << Also you can always pay for a service repair if the patched modems do not work.
important NB: TWRP recovery do support EFS backup with encryption, so i guess it is great to have a sensitive data such as EFS to be backed up with encrypted password, so i do recommend using it as a backup
Hello All, I'm pretty new to all this and am feeling out of my depth, however getting desperate and don't know where to turn next.
I am in Australia and purchased a brand new GT-I9300 from eBay around 3 weeks ago which was shipped from Shanghai, China.
It turned up running 4.1.2 and worked just fine. I tried using the software update feature on the phone to see if 4.3 was available, however, I got the error message to say that because the phone had been modified, software upgrades were unavailable. I mentioned this on a local forum here, and someone kind offered to help me upgrade to 4.3 using Odin.
Turns out the phone was shipped to me rooted and had SuperSU installed. Had to install and run Triangle Away to reset binary counter first. Then installed Odin and followed the links to the firmware and this is where it started going wrong. Fist attempt resulted in a boot loop and could not enter recovery mode to factory reset, however could access download mode, so flashed with 4.3 recovery firmware which got the phone to boot up. Then flashed 4.3 stock firmware again, which was successful this time. However, when trying to make calls or send text messages, the error message on the screen is "Not registered on network". Have tried going back to 4.1.2 and upgrading using Kies, but same result. Then tried the patch from here http://forum.xda-developers.com/showthread.php?t=2745274 and still no luck.
I then sent the phone half way across Australia to Official Samsung Specialist Repair Centre, however, they called me yesterday, to say that because it was an international model, they can't/won't help as they don't have access to international firmware.
If anyone here can help me to get this phone working again, I would be very grateful. Thanks.

Thank You. The phone was posted back to me yesterday, but I won't receive it back until the end of the week. Once I get it back, I'll try this out.
I'm very sorry to have to ask this, but could you give me a bit of a step by step by what you mean?
Thank You again.

Many thanks tallman43, I managed to get someone to give me a hand with giving your idea a try. Just wanted to let you know that it worked, and my GT-I9300 is now back up and connecting to the network and running with 4.3. Thanks again, and much appreciated.

Same here (Think we done the same thing with the Marshmallow 6.0.1 leak) I backed up, but the new version of TWRP I have has EFS as a separate option, I never even noticed and never backed it up.
However I Flash with smartswitch, and after reflashing the bootloader with odin and a Root Kernel, I can boot into the device and using root explorer, I CAN see my EFS folder. I deleted the .nv_data.bin files and changed the .nv_data.bak to .nv_data.bin (was an older date) and I now have the network options back but a generic IMEI and can't register on a network.
I feel SO close to getting it up and running, but if smartswitch can't help, not fully anyway, I'm not 100% I can be rescued either.

I've called to my local service center and they said that they will reflash firmware fo 450 CZK (about 17 euros) and It will be done in 1 hour 30 minutes. So I will se what they can do with it. I've tried everything... and right now I don't know what else I can do. But If you figurate out how to fix it let me know Thanks!

So my progress is that phone can now see networks, but still have srong SN and IMEI and also can't connect to the network...

I got 3 old smartswitch backup and i find a file with the imei and everything , do you think its possible to backup this files ?
You CAN recover your phone with smartswitch, there is an emergency recovery function with a IMEI and SN input option, some users who used the same threat (android 6.0.1) and has lost their efs partition reported that smartswitch worked.
I've done this procedure too for some weeks to recover my phone an everything is working fine.
possibly with root explorer

Damaged EFS Partition?

Hi All, I have a Problem. I have Ruined my Edge. Genius.
I have some how (read: Messed about with incomplete ROMS) damaged/Repartitioned my EFS partition. I can boot into the device and I HAVE an EFS folder with files in it, but still an IMEI 3500000000000000000000 or similar as well as no signal.
I know Its stupid, even more so to not have a backup, so you don't need to remind me, but any ideas on rectifying this? I know some people have had to get a new Motherboard installed when the EFS partition is missing or empty, but mine is there. I'm hoping something can be done. Maybe a .PIT file? I dunno....
TO NOTE:
I HAVE tried Smartswitch. NO, It didn't work :laugh:
Any help would be Apprectiated
