I have a quick question because I've run into a problem I can't seem to fix.
First, so everyone knows what I'm dealing with:
Phone: i717
Changes: Rooted (Shows super user access), CWM v5.5.0.4, Unlocked (Tested)
Rom: Stock AT&T Rom
Sim Card: Works in a T-mo branded Exhibit II 4G.
I flashed a radio (tried KID, 0331122 from the radio thread in the dev section, and reflashed the original AT&T radio).Even w/ the original radio installed, it cannot seem my T-Mo sim now.
Do I need to flash a new Rom or what? Wipe data to factory reset?
I would rather not change anything w/o asking since flashing radios seems to be a straight forward thing that most ppl have done w/o touching the rom.
Thanks ahead of time.
Mine worked with a rooted stock rom at first it didnt see the sim then i tried searching the network under wireless and networks it took a few minutes but then it came up.

don't forget if you are running an ICS based ROM you need an ICS based Radio/modem.
EDIT: i see you're running the original GB rom so you need the GB radio.
give it a few minutes to find a signal or go to settings/mobile networks/network operators. choose manual. then let it search a few minutes. then select t-mobile.
I find the Blaze 4G radio worked best for me, but depending on your area, your results may differ. try em all.
You guys are insanely fast.
I'm currently on the stock radio & I'm still getting the same message after letting the sim sit in the phone for 9 minutes (yes, I watched the clock, lol):

Where should I go from here?
Edit: Is the answer flashing another rom? Maybe something has become corrupt? I don't see how as I've read & re-read walk thrus for doing this to make sure.
I've done a little more reading. Flashing the beta ICS rom flashes to the old AT&T modem.
Would this be the best bet?
Edit: After looking through the "about" phone...
I'm on 4.0.3
Baseband: Unknown............. that's really bad.
Edit 2:
After reading, I needed to back up the EFS. No where is this stated anywhere, unfortunately. That contains IMEI and everything else.
Edit:
So, after reading MORE, the IMEI number is on a sticker behind the battery, along w/ the S/N.
Huh? Efs? I dont even know what that is nevermind backing it up. Goto clockworkmod and flash the radio.zip and reboot. Thats all there is to it.

If you look up EMEI number related to flashing the radio, there's a lot of hits.
XDA has a thread on it here: http://forum.xda-developers.com/showthread.php?t=1352371
I'm quite shocked it's not mentioned everywhere as this happens to people now and again.
I have my IMEI number, i just don't know how to input it into the phone.
As for flashing the radio, I've flashed 2, then back to the original. To no avail.
Sorry never had anything like that. I would almost odin back to stock and start over. You dont need root for the sim to work on calls and edge with tmobile.

If you're baseband is unknown don't worry just flash a stock at&t modem and it should go back to normal. Your imei is under a different menu in about phone..the status one.
Also its no ones responsibility to tell you that modifying your phone may break it.

I did flash back to the stock AT&T baseband as stated in the original post.
If I go to About Phone, the Baseband Version is unknown.
If I go to Status, the following are listed as
Network: Unknown
Mobile Network: Unknown
Service State: Out of service
Mobile Network State: Disconnected
IMEI: Unknown
IMEI SV: Unknown
I've backed up the EFS that I have no just so it doesn't degrade further. I'll try to flash again and see, but I still think the EFS is borked.
I'll see what I can, but I think I'll the EFS is borked beyond flashing it to normal.
My point about the EFS back up is that most ppl here don't seem to know what it is. It shouldn't be that foreign of a topic since flashing a radio is obviously problematic for some. I've seen other posts concerning no IMEI after flashing radios on forums other than XDA. It's odd that it's not mentioned as a sticky everywhere.
Backing up EFS would solve a lot of head aches from unlocking / radio flashing woes. I'm hoping this info will save a few people a lot of time and money.
After more digging, I came across this thread:
http://forum.xda-developers.com/showthread.php?t=1646326
Synopsis: Basically, he followed the same guide I did. The only difference is that I flashed the radio while using a stock AT&T rom. Once he flashed back to GB (saurom), he gained back his baseband / IMEI.
This is what I cannot figure out:
CWM will see and flash any radio file I push to my note. If I push a stock AT&T rom, it won't see it. If I put the rom in it's own folder, it seems the rom, but states there's no files.
Is CWM corrupted? Why would it only read firmware to flash radios, but not android roms? Should I just go back and install CWM?
I've searched all over & used google, but I can't find a thread discussing this.
Fixed.
This problem has nothing to do with any of the radios corrupting the EFS folder. Albeit, it's always a good idea to back it up.
Flashing back to AT&Ts stock rom (2.3.6 or 4.0.3) never fix the issue. You will always be stuck w/o a radio, at least from what I've seen. Even flashing back to the stock radio fails. I don't know if it changes the EFS, but AT&T's rom does not like it and shows no IMEI & a bogus SN .
I had to go back, flash to saurom and a compatible GB (or beta T-mobile) radio to get te work fine. ICS radios work fine on ICS.
Saurom and GB radios dont work in my i 717 trying to connect to wind. I got a CM 9 ICS build and ive tired a bunch of radios. they all failed. i keep getting no sim errors. I can see the operator but when i select it it times out and says it cannot connect to the network at this time. it also says interset sim. Im positive it is unlocked.
Modems(radios) or basebands should have nothing to do with whatever rom you are running. Whether they are GB, ICS, or JB modems, they should all work to a degree, at least for phone call ability. I have flashed many different radios trying to get the best function of my att note on t-mo. The best I got was using the Blaze modem. That got me 3g hspa.
The worst will be just giving you edge speed. My note is unlocked and has been on JB running blaze ICS modem working fine. Maybe you need to start over, evaluate what you have, and go from there. There are great threads on att over t-mobile. Good luck.
I picked my rom, and started flashing 5 or 6 radios, and found what one worked best on t-mo.
Presently, I have switched back to att- sort of- straight talk. I'm not thrilled with the speeds. No higher than 4 mbps DL, and 1-1.5 UL. Thinking about going back to t-mo and dealing with the slow UL speeds. I'm on an ICS rom with the ucle6 modem.
Also, flashing a rom does not change your modem. You have to physically reflash the modem you want. Some modems show up as unknown under the baseband. Blaze is one of them.
Another thought- sometimes a reboot will get your sim recognized by your phone.

This is yet another case of the "no sim" bug ....
Damn I wish we could find the answer to this issue, but none exist .....and for some users the return to complete stock even fails to recover service ..

Really what an incredible unlucky glitch.I got my note for only 360CDN good condition but missing the stylus, even still it was a good buy. I'm on Wind mobile, T-mobile here in Canada. I even gave it to somebody who's done a bunch and they ran into the no sim problem. I guess I'll be going back to my HTC HD2 and sell the note .
---------- Post added at 11:48 PM ---------- Previous post was at 11:44 PM ----------
So just to confirm I have followed the process correctly over 20 times and no matter which cm9 cm10 based rom and any ics or gb based radio will allow connection or recognize the sim to the 1700 aws network. With a cm9 based rom I can see my network, but it will not allow connection like the phone is locked, even though i have unlocked and tested the phone on other networks.

Yes, I have the same 'No SIM' issue with a working WIND SIM. I've tried everything, multiple Radios, multiple ROMs. Very strange problem. I wish we had the tools that the SGSIII has for dumping and restoring the NV ram. Even stranger, I do have a the correct IMEI number in Phone, About. I have a feeling it's something to do with how the phones were carrier unlocked.

I have made a backup of the EFS folder with EFS Pro. I tried restoring the NV ram from .bak but there was none found.

It has nothing to do with your unlock. If you've followed the steps and are still having no sim issue you may have to get a new 32k sim card from wind the older ones won't connect in a phone with lte

Had to replace the TMo SIM card with a newer one today. Solved the problem of "No SIM".
I know this is old
I have the same problem with "NO SIM." One day i flashed so many things to my phone and one time i turned it on i got ATT on the top right corner and everything was good. I made some phone calls and texts and even browsed the web. I restarted the phone to check if it was just a fluke and it was. Ever since then i cannot get it to read my phone, but i know for sure the hardware works.
I can't post to the dev forum, so maybe someone over here can help:
I tried the PA ROM, because I really love the hybrid mode. The ROM has worked fine and looks great, but whatever version I flash, the mobile network, both data and phone, simply doesn't work.
It briefly connects to my provider (drei.at) and immediately disconnects, no matter whether I have data connection enabled or not.
Have tried this with all available versions of PA and did the usual routine: wipe, format system, wipe data. I even went totally back to a stock ROM, tried various modems, the current one being XXDLH9, which works just fine on [email protected] 0.6 ROM.
Had the same problem with Omega, FoxHound, and god knows what other ROMs I tried. No matter what, the only JB ROM actually working is [email protected] 0.6, that's it.
Is this a known phenomenon or have I overlooked something obvious?
The phone used to be a branded and simlocked Austrian T-Mobile, but ever since it has been debranded and SIM unlocked.
Any ideas?
All i can suggest is your apn settings?
Can try Offline SIM APN Database (get on Google Play) to insert the correct apn settings.

Thank you for the suggestion. The APN settings on a fresh install, all wiped, are correct and the same as in a working setup.
Any other ideas? Am I really the only one with that problem?
Modem tried APN correct .
Suggest next step is factory reset ..
Step after that is to install an official stock rom .
Others who may have a problem post in the roms thread .

Did a factory reset, totally clean install with everything wiped.
Also, did a clean wipe and installed official stock ROM. Lost root, started from scratch and still didn't work.
I'd love to post in the ROM forums, but haven't yet posted my mandatory 10 postings.. Maybe this thread helps me to reach that limit

No, that's not what I said. Stock ROMs work just fine; I actually just flashed the latest leak (DLI5) and had no problems with the network. The problem hasn't changed, so it's what I wrote in the OP: Only JB to work ist latest leak and [email protected] 0.6. All others can be installed but have not network connection other than WiFi.

Thanks for trying to help.
Yes, I have been playing around with all kinds of basebands, trying to flash modems etc. but that does not seem to be the reason for it. I have had different modems working and the very same modems simply did not work with PA at all. Best example ist yesterday's leak DLI5 which I flashed and had a virgin like system working just fine with my network. I then flashed the PA ROM, which then had the same baseband as the latest stock ROM, but, alas, same story: No network.
The weird thing is the brief connect it always shows in the status bar. It lasts roughly 4-5 seconds and then disconnects again, only showing the empty network status display.
It really sucks, because I find the idea of hybrid ROMs really appealing, in fact, this seems to me as a truly superior way of making use of the 720p display.
Need to try logcat next to see whether the connect/disconnect somehow can be monitored from there. Will report on that.

I just installed ParanoidAndroid. I'm kind of a noob to all of this.
I understand some, but not all.
My mobile networks are not working.
I don't get any notification at the top of the screen either saying I'm on a mobile network.
I've messed around with the APN settings. It seems that every now and then it'll connect for a brief moment, but I can't really do anything unless I'm connected to WiFi.
Any help would be appreciated.
I came from a stock phone rooted.
Installed this and now I'm here.

Hey there!
Before anyone asks, I have done the following.
Searched on google/XDA for solutions
Flashed different ROM's
Changed Kernels
Wiped all cache
Did factory Reset
I am currently having bad network problems with my phone.
I am running JellyBam 6.7.0 with default kernel.
Baseband: XXLQ6
Problem
I constently get No Service or "Emergency Calls only" in areas that I've never had emergency calls in. I am not aware of my old modem or RIL, and so am completely lost of what to go from here as I haven't found posts that could help my issue.
When I reboot my phone, turn airplane mode on, or just randomly it will go into the stage above, to where it will stay without signal for 10 minutes up to days (I've had it go for 2 days with no signal). When I try to search for networks (In places where there is 100% a network) it will say "error searching for network".
I have no idea what to do, and am rather scared. There have been 2 emergency situations to where I needed a phone, and yet mine had no signal.
My second question, is if I manage to get it back to stock ICS (4.0.4) and do all the updates through KIES, will I get the original modem + RIL back as well as the ROM? Or will I still need to flash that myself.
TLDR: If I reset it back completely to stock ICS, will everything that I have done (root, flash modems, flash kernels etc...) be erased.
Thanks so much for reading, I've got so much stress rigt now.
Are you getting no service all the time or only intermittently ? Also, check your IMEI in settings/about phone to see if it's the generic one (0049.....), whatever you do tho don't post your actual IMEI here. Just a yes/know answer to the 'is it the generic one' question will do.
If it's a constant thing, call your carrier to check if it's been IMEI blocked. If it's intermittent, flash a stock ICS rom as you'd suggested. You'll end up with whatever modem/baseband is attached to the rom you flash, and yes, you'll lose root & the kernel you're currently running will be replaced by the stock kernel in the rom you flash.

Yes it's only intermittent, so not a problem with the IMEI.
So if I find, and download stock ICS to bring it to factory it should be fine? If I were to, let's say, flash the ICS onto the phone, is there any way to keep the RIL+ Baseband and flash back JB? Or when flashing JB, will it replace whatever RIL+Baseband is attached with the ROM.
Also, thanks for the quick reply. I was expecting days for a response.
Forget about JB/custom roms/anything else until or unless you get your phone working normally again. Flash an ICS stock rom for your region.
And forget about the current RIL/baseband. It sounds like it may well be the cause of the problems you're having; quite possible if you've been mucking around with different RIL's in particular. Pretty sure I said in my PP that you'll end up with whatever baseband is lumped in with the stock rom you flash.
Actually, you might want to stick with a stock rom specific to your carrier if there is one, at least that way you know the modem/baseband will more than likely have been tested by your carrier & is likely to work well with it unless there are other issues (carrier side connectivity issues or other problems with your phone).
As to whether doing this will fix your issues, no idea. At the moment, and in the absence of any clue as to what's causing your issues, it's the best option you've got. If it doesn't fix the problems, then it's probably a carrier-side issue (possible given it only happens at certain times/in certain locations) or a physical problem with the phone (less likely).

I'm having problems to what official ROM to use from the list.
The only one on the list is Optus, but my phone is with virgin (on the optus network) should that be fine?
The rom is I9100XWLP8
Once again many thanks! I'll update you with the progress.
Yep. Flash the Optus rom given you're effectively using their network & see what happens.

Just downloaded it (Hotfile takes forever) and flashed through odin.
Worked fine after a factory reset. However, Kies won't update my phone.
Network seems to running smooth, so we'll see how it goes. The more things I do, I guess the more things I can rule out.
EDIT:
I updated the phone, and I get the message "Unfortunately, Application installer has stopped". What am I supposed to do?

That didn't work.
Anyhow, I managed to track down a 4.0.4 variant of the ROM I was using, and made sure the CSC, PDA and Baseband all matched up with what Kies wanted, and flashed it. I think the error occured I was trying to update a ROM with the wrong CSC and Baseband to one with the correct ones and Kies didn't like that.
I run CM 10.1 on my phone, which had original specs: PDA:KG3 / PHONE:KE7 / CSC:KG1 (VNZ). I've been running those CM nightlies since about November 2012 with few problems, updating to new nightlies every few weeks to a month. I'd never flashed new radios - just the CM rom.
Starting a couple of months ago, I began to see a problem where my phone would drop cell service (no bars + empty triangle in the cell signal indicator) and rebooting was the only way to bring the cell signal back. This happened every couple of days, so was bearable. I figured something in the nightlies had caused a weird problem and that the CM devs/community would find and fix this.
After flashing a nightly last week, my phone wouldn't hold cell signal for more than an hour - sometimes not even that. Reboots fixed this but never permanently. I started to read about radios, modems, and RILs. hawkerpaul's post here was a great help. I found that my phone had the original KE7 radio but had a RIL of I9100XXLS8(2) - I presume from the CM rom? I flashed some new radios and have now gone through a series of the (matched) modem + RIL files in hawkerpaul's post above. In most cases I see the following behaviour:
Phone successfully finds network (Vodafone NZ) on boot
Trying to manually select a mobile operator fails (error when searching for networks)
Unable to successfully call out! Dialling stalls, and I can't hang up - only fixed by a reboot
How do I fix this immediate problem of not being able to call/receive calls? Seems like maybe I'm using a radio that doesn't work with Vodafone NZ - but I haven't seen any posts on what DOES work well with that network. I have the modem file to flash the original KE7 back again, but what should I do about the RIL file then? Not sure I have found an RIL for KE7 yet in my travels. Any help would be appreciated - and thanks!
To help me figure out where I went wrong, do the CM builds include the RIL, or is that something that could only get updated somewhere else? I know the rom doesn't change the modem but I suspect that XXLS8(2) RIL had to come from CM.
1) Don't mess with RIL's (You'll make it 'worse').
2) Check stock roms released by your telco. Find out which modems were bundled with those stock roms. Try those modems. If they don't help, look for stock roms released by other carriers which sold the the I9100T world-wide (check Samfirmware). Try the modems bundled with these roms. If they don't help, try any & every modem you can get your hands on.
If you've already flashed RIL's, you may well have created a bigger problem for yourself. You might want to do a clean install of stock as well for good measure if that's the case. The reason I stopped using CM9 (and never bothered with CM10) was similar issues that seem to have gotten introduced with a particular nightly & never went away (a fix was tried which benefited a very few problems who were having RIL problems but created problems for even more people who previously had no problems).

I'm just about at this point. If I reinstall stock, will that reset my modem as well?
Thanks for the help - looks like I did definitely make things worse.
You'll end up with whatever modem is bundled with the stock rom, so probably use the most recent released by your carrier, then you can try other modems released by your carrier as per my PP. The rationale with that is you'd hope your carrier has tested the modems they bundle with their stock roms so they work in most places/at most times with their network. Doing a clean install of stock should fix anything funky messing around with RIL's may have done as well.
If you get no joy from those, proceed as per my PP (You might get other suggestions from other people as well).
Thanks for the help. I was able to flash the latest stock rom, which included baseband I9100XXLS8. This worked fine for making and receiving calls. I lasted a couple of hours with that stock Samsung firmware before I started to get itchy for Android 4.2 again, so I've now rooted and am going to try CM10 again, but at least this time I know not to touch the modem - and I'm confident I can get back to stock again if I have any problems! Many thanks!
Glad you've got connectivity back You can flash modems as much as you want, I'd just be wary of messing with RIL's unless it's as an absolute last resort (I.E you have no connectivity & you've tried every single modem. Too many people try them when their connectivity is fine in the mistaken belief they're going to get 8Mbps instead of 7.8Mbps downloads, I.E it wasn't broke in the first place), even then a clean install of stock & choosing the right modem will often fix the problems.
You're welcome Any dramas post to this thread again & I'm sure someone will help.

Hi and thanks in advance. I have a galaxy i9100 which shows the following information: PDA: i9100xwlsd - Phone i9100xxls8 - Csc i9100vnzls9. I installed via odin Android version 4.1.2 which made the phone work really well except that it kept dropping network service and signal strength. I replaced the sim which did seem to help but did not fix the problem totally. I also notice that the GPS will not find any satellites and just keeps searching for as long as I would let it. I have read various threads and it appears that this may be a modem problem? I have found that Vodafone NZ has released a modem which is i9100xxls9? Should I flash the modem file only in Odin and do you really think this would fix the problem. How would I flash the modem file. Would I do this through odin? Any help gratefully received.
Yes, first step is definitely to flash the modem which was released by your carrier for your region. If you can find a file which is Odin flashable then yes, try it. However most of the files are for flashing via CWM. Are you rooted? If not they won't work for you, in which case you'll have to search around for an Odin flashable version of LS9.
Just to check, you do have an i9100? Not an i9100t etc? Some variants require different modems.

Thanks for the response. How do I know if a file is odin flashable? How do you flash via cwm (whatever that is). You can see I am a little bit or a lot of a novice on this. The unfortunate thing is I enjoy it. I think the phone is rooted and it says the phone is: Model GT- i9100. The phone was purchased in UAE and I have flashed the android 4.1.2 which was a vodafone NZ system. Everything works fine except the GPS and the phone signal drops out all the time showing no service when there is service? Thanks again for your help on this. I have just found that the phone may not be rooted? I tried to install root manager but it indicated phone was not rooted?
Ok so no offence, you need to do a lot of reading for yourself. Reading is the key to successful (ie without bricking) modification of your phone.
For a start, if you've flashed stock then of course you will not have root. You don't need to have root to flash a modem. Have a look here:
http://forum.xda-developers.com/showthread.php?t=1656005
I'm not saying to flash that modem file. But that's how you do it, now you just need to find your file and flash it.

Hello all,
My partner bought a Galaxy S3 (GT-i1900) International (I live in the UK) off a friend .
We noticed that the network connection periodically failed. I noticed that the software was some of the earliest on this phone, and so i thought I'd better update it, as it was suggested that sometimes if the phone is running some of it's earliest software it can cause problems with the network connection, and as it works 95% of the time, surely it can't be the antenna? I went to software update and tried to update it there, it's then I realised the phone had been rooted, and even Kies would not update it. I came to the conclusion that perhaps my friend had tried to mess with the phone some how, and may have caused this network problem, or perhaps was trying to cure it? Who knows
I decided to flash the latest stock rom (i9300XXUGMK6_I9300OXAGMK6_I9300XXUGMK6_HOME.tar.md5) I found on Sammobile. Everything went well, the phone booted up perfectly, the only minor worry being that the first screen was in Polish, quickly remedied by changing the language to English UK. All seemed fine, until we tried to make a call. it was then we realised that there was no network connection whatsoever. I tried other sim cards with other networks - still no connection. It only shows the signal bars.
I read the forums for a couple of days and tried:
Going in Network Settings and searching for my network, 3, which it found amongst all others. it said 'Registered on Network' but then immediately flashed up '3 network not connected' or similar. fail.
Installing CWM recovery, then flashing the 2 modem zips (DDEMG2 & XXDME4) all went fine, but the phone still says 'disconnected' under Device settings Mobile network state
Using the Ariza patch. I tried this, but on the last step where it says 'just click patch' mine gets stuck on a downloading state, possibly as I'm using a stock rom I read some kernel has to be changed first? - Beyond me.
It was then I decided to scrutinize every difference between my working S3, exactly same phone on same network, and my partners.
The IMEI number was correct, something I see people have problems with. The signal strength reading are the same, suggesting the antenna at least is fine.
The serial number - Now this is the ONLY thing I can see that seems to have been changed, from the correct format, to one starting with 4df1 ...... Is this the problem, that has made the phone not register with network? In the UK phones are not locked into a specific phone number /contract and so I don't see how the network would decline a differing serial number?
Anyway that's where I'm at a phone that has no network connection, with a differing serial number.
Any help would be GREATLY appreciated.

Screenshots of the device status in case that helps . SCREENSHOTS REMOVED DUE TO PRIVATE INFO
I've noticed after Googling the baseband version, it says 'New modem DDEMG2 (16/07/13) India,Sri Lanka,Bangladesh'
I live in the UK and have a network free unlocked unbranded International S3!
Surely the steps I followed to flash the modems as stated above are incorrect?!
Do I need to flash the UK one?
Anyone know which one for 4.3?
How do I do it and where would I find it?
Any help greatly appreciated!

Go to Samsungmobile and download 4.3 BTU ( it's for Uk,simfree phones.) Flash via Odin,maybe that will help

Hi couple of things first you have posted screen shots with your mobile no and Imei no on I would delete them
I am pretty sure flashing another rom won't fix your issue you can easily use roms from a different region and still have full network connection but you can give it a try as suggested above.
First thing first because you have upgraded your phone your efs as changed from efs v1 to efs v2 (which you probably already know) flashing the (DDEMG2 & XXDME4) modems would not work because you need a modem later than mg4 for 4.3 roms.
What you need to try is flash a patched mk6 modem and kernel from here >> https://drive.google.com/folderview...sharing&tid=0B6MIUd7HJudAbU5YaGkzOUowMG8#list << flash then reboot if you get stuck in a bootloop factory reset and wipe cache in recovery.You could also try this >> http://forum.xda-developers.com/gal...ii-network-problem-update-sn-t1918601/page199 << look at post 1984 this is basically the same thing with a rom included and as had some success.
If the patched modems do not work and you don't have a efs backup then I would suggest you need to send for repair.

Thanks. I have absolutely no idea what EFS is or how to back up. I would never have usually played with a phone like this it's just my partner was getting fed up of the connection disapearing every now and again, forcing her to reset. I have about 12 hours worth of knowledge on root access, flashing and modifying phones. I am worried I'm going to completely brick the phone. Is there anyway I can make a back of the phone as it is so that if I mess things up I can some how reset it, as at the moment I have Nothing as such. I am going to read up on EFS, I suspect due to the fact the phone was already rooted when I bought it, yet still stuck on the original software and and not updated in anyway, with a pre-exsisting network connection issue, that the phone was already un fixable. I hope not.
I will try all the steps suggested and post results.
Thanks a lot people
ps i hardly have any experience of using forums so sorry if i'm making a mess of this

Don't worry just take your time and read all the guides if you install a custom recovery you can do a nandroid backup which is basically a full backup of everything on your phone and will restore your phone to how it was before (if you do it right) I recommend using PhilZ recovery and flash it with Odin.

I have cwm recovery will this suffice?
I'm using Samsungtool as we speak to back up the EFS folder.

Yep that will do fine although you are backing up a partially corrupt efs that's the reason you are not getting a signal because the efs v2 can't read the modern correctly that's why you may need a patched modem & kernel to help read it.But back it up anyway in case the efs gets any worse and gets totally corrupt.

That was my thinking, the IMEI isn't corrupt yet so I thought best to back up what I have. Ive also backed up using CWM.
Im now trying to flash the proper version of 4.3 for my unlocked uK S3, so im at least using the correct os.
Im flashin zip from cwm, but when i select it on my sd card, it says the following:
Finding update package...
Opening update package...
Installing update...
Installation aborted.
Any ideas why it won't install? Iv'e been Googling it
for 2 hours.
cheers
update - I spent ten hours downloading the proper rom 4.3 btu uk unlocked one, finally flashed it using mobile odin.....
started in Polish again - with no network. I think that this is standard.
Next, I am going to try to flash the patched modem.
tallman43 - do you think my strange serial number needs to be corrected? Is this possible or necessary?
Many thanks - one very tired migraine creating finger-nail biter.
Update:
I finally got the phone to work by following the instructions on the page below;
http://forum.xda-developers.com/galaxy-s3/help/guide-fixing-gt-i9300-network-4-3-stock-t2609635
The patched kernel didn't work on it's own, but the kernel I installed from this thread, along with the other two files, seemed to work, and though the phone is now registered using a much better Android 4.3, it still disconnects every now and again forcing a restart. I really wish I could work out why it does this, I'm starting to believe it may be a hardware issue now.
Is there a program that I could use to test the part of the phone that malfunctions and loses signal completely, to try and work out what is happening when the phone suddenly loses all signal and shows only a circle with a line on it (no sign)
Many thanks to all the people who helped me with this I really appreciate it.
I want to close this thread now as what I require now is off topic from the original post so many thanks for your help people.
