I'm sorry for being a noob, but i tried searching for anything similar and i couldn't find it. I have the weirdest problem, i flashed openOptimus today and it booted up just fine (i did the official gingerbread update so i was on new baseband). I checked the software version, it was v20 after the flash. After a few reboots settings.apk crashed on boot, and the software version was back to v10c-OCT-12-2010. I tried re-flashing after wiping absolutely everything, 2 times,same thing. I tried ciaox's guide for updating baseband with LGMDP tool as posted on his thread, did not update the baseband (even tho the process was finished successfully). If anyone had or has a similar problem, please enlighten me with a solution, if not any suggestion is welcome, thanks
1. rom downgrading by itself? r u insane? lolz
2. Read dr. notor's thread from start to beggining here. check which baseband version u're on using lg hidden menu cuz i'm almost sure u're using a baseband that's incompatible with your current rom.
3. do u have gsm signal?
edit: it's most definitely not open optimus' fault cuz i've used that rom w/o any problems, u proly screwed something up during the upgrade/flash process. but have no fear, with some patience and forum digging u can fix it hehe

Yes i am aware that its not openOptimus's fault, and that i probably messed up somewhere along the line. I read dr. notor's thread from start to begining, its the same process from ciaox's openOptimus thread, with screenshots added. As i said, after a few reboots settings.apk crashed and when i checked settings>about phone, in the Software Version field it said 10c, as opposed to the 20c it said prior to the reboot, i am not sure how or why this happened, but i am wiping everything, reflashing the rom, and reflashing the baseband now to see what happens. Also, i did have a gsm signal. Thank you for the reply
Ok, then u prolly should pay attention to this part where he says
Q: How do I know it worked?
A: If everything worked, you will have a working GSM (calls, 2G/3G data) with the proper ROM installed.. On stock ROMs, you can check the baseband version via hidden LG menu. It will show AMSS6150 if you flashed v20G baseband. If you see AMSS6038, then you have a baseband from v20[ABCD...] versions. If you see anything else, you have a baseband from v10? ROM. LGMDP utility also shows which ROM version does the baseband come from (see screenshot attached). Note (CM7 users): V07u-000-000-MAR-23-2009 is NOT your baseband version but some irrelevant CM7 crap.

Like I said, check your baseband version using LG Hidden Menu (dial 3845#*500#).
Hey, its strange it seems to be just a bug, it happened again after i changed the settings icon and rebooted, but lg hidden menu reported baseband as AMSS6038, while settings > about phone said 10c, after a reboot it was v20 again. Im stumped, its fine now tho,thanks

Been trying to get my phone to run fully on gingerbread, and have tried the official v20e.kdz flash, as well as Mik_os's CM7, both worked great, and I liked them a lot.
BUT, I can't get my 3G/Data connection to work on either. WiFi works fine, and I can connect to the internet fine that way.
So I am currently flashed back to the gross V10V 2.2.1 Froyo until I can get it figured out. I REALLY want to run CM7, but with no 3G I just can't really use it.
Searches have returned nothing. Any other canadian guys out there with this same problem?
I have a data plan, and I am with Koodo/Telus.
I believe it has something to do with the baseband.
Look here: http://forum.xda-developers.com/showthread.php?t=1217504
Already checked it out, but the V10E image will not work with my phone. I need the V10V image for it to work. Is there a 7z for the V10V platform?

If you want a custom ROM, select one that corresponds to your baseband or switch the baseband. If you do not, you will have no data. That is all to it. End of story.
You can extract the baseband yourself from KDZ archive. http://forum.xda-developers.com/showthread.php?t=901417 (steps 1-2).
All of this covered in the sticky thread.
Got it. Currently have extracted needed files from the uncompressed dz file for my stock ROM. I will be reuploading CM7 and franco's kernel,(Lots of users seem to have luck with it, and I liked it when I ran it for a day) and then flashing my V10V radio and I will let you know!
Edit:
Wait, CM7 currently has a bug so 3G/Data does not work? Shoot! Or am I fixing this by flashing my stock rom's baseband? Will find out soon enough....
And I admit I'm a bit of a noob, I only started doing this last week. I'm learning though.

No dice. My phone was in its factory state when I began this project. It was rooted, installed AmonRa's custom backup, and I installed DrellisDee's Kernel so I could overclock with 2.2.1 froyo. Was stable at 480/768, but it still wasn't enough.
Nandroid backup, google backup, cleared cache, and dalvik. (Thank your AmonRa!)
Flashed CM7, latest stable release 6.5.7
Flashed franco.Kernel.v1-16082011
Booted up, currently running with no issues. Flashed my V10V baseband using LGMDP v1.5.exe .
No errors, everything went well, battery still at 92%.
Still no internet unless connected to WIFI, Damn. Guess I'm S.O.L. on this one eh?
Thanks for the help guys. Gonna check out some other Ginger ROMs and give them a try to see if I can get ginger to work with my 3G network. Any suggestions? I'm stuck with v10 based ROMs since LG hasn't released any V20 setups for my network.

You can't tell me how you got the phone rooted in the first place can you?
I'm with Koodo and have the Froyo 2.2.1 firmware on there.
I've tried everything I can do to get it rooted, and it just won't!
Gingerbreak says that there is a problem and won't do it.
Superoneclick hangs on step 6 which is mounting the SD card
I tried to grab a v10_G flash which is the telus stock ( I think ) but there was an error while trying to flash with kdz flash ( update error param =2 ).
Can ANYBODY help me to figure this out?
I havd koodo, just last friday I rooted 2 friend's phones with the gingerbreak app from xda thread. I took the second one and at first it didn't work because there were too many dots in the file name, simple as that, took me a while to figure it out, so I renamed to something like gingerbreak1.apk and it worked. For the data not working, just google " koodo apn " then you'll end up with the good apn info wich is simply. " sp.koodo.com " , port = 80, NO proxy as it just slow down the net, the other settings as they already are, 302 and 230 or something like that they come as default near the bottom of apn creation option in mobile options. All other fields leave blank. Hope it works..

I decided to install a different version of gingerbreak, and suddenly everything worked so simply...
I have since installed clockworkmod and have done a full back up.
Then I installed cyanomod and everything is up and going.
I was nervous to flash the google apps, but everything is happy.
Oh ya... I did have to update my apn data to the koodo network. I've tested MMS in and out.
You might want to try Andy's Phoenix rom; the fastest one and amazing statusbar. Some light text issues will be fixed the 20th october update. Beside that, the best for me with franco 2.6.35.14 oct. 2 kernel. Anyway, glad you could make it

Hi all
I dont know why / how but my cell radio suddenly went off and wont turn back on.
I am rooted BL unlocked on Nottachtrix 1.3.1 ROM.
I am also SIM unlocked and I live in India. I have the AT&T atrix.
What might have caused the issue
I was messing around in *#*#4636#*#* with the radio band.
I had this signal boosting app which I use but cant find it on the market to link it now. I 've been using this app for a while so dont know why it would mess up now.
I am not sure if these are what caused the issue but just letting u know
Things I have done so far
Battery pull
Different sim card / different network
I tried flashing the ROM again with full wipe but still no luck
Flashed CM7 Ba2tf and the problem persists.. can I rule out that it is software related?
Everything else is working fine.
I am out of ideas and help is very much appreciated.
Thanks
SOLUTION
The Easiest Fix for this issue is Flashing the right baseband in CWM recovery.
The radio is flashed separately from the Android os. Try a new baseband. However be sure to get the right one for your phone.

Issue solved. I 'll detail what I did so it can help others.
Yes. Selecting the USA Band is what caused the issue.
I dint know that basebands could be flashed on Atrix ROMs. I wish I 've known it sooner. Would 've saved me a lot of trouble. Anyway I went with the SBF method.
I had the 4.5.91 earlier but I went with 4.5.141 to be safe.
Everything went smooth but at the end RSD lite said "Please manually reboot this phone" and the phone went into a boot loop at the M logo. I looked around and after a while found that a Wipe fixes it in stock recovery.
1. Disconnected the phone
2. Pulled out the battery.
3. Rebooted and went into stock recovery.
4. Wiped data and rebooted.
5. Got to home screen fine. Rebooted once again to make sure everything is fine.
Then inserted sim card and I had a signal. Everthing is working great.
Bro i have solution.... Btw... You must have flashed the wrong rom.... Kindly download nd install other one ..or use custom cm14 ROM or miui for best experience..
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).

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.
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.

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

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.

My phone is a international variant, made in Vietnam, i also tryed to flash 4.1.2 I9300XXEMG4, so then i can flash MG4 modem which can still read the modified EFS...if it is modified, but didn't work.., i think i need to send the phone to a gsm/service, but maybe you guys can help me without cost me money..

thx man, i hope someone knows how can i solve the problem.
What had you done before you got to this issue of no cellular signal?
Did you flash a custom ROM etc..? Which version were you on before? 4.3?
What did you do after you found out about this issue? Did you by any chance flash an older version?
Because that tends to do that, atleast that's what happened to me.
I had a wrong/fake IMEI ("0049..."), which caused that I had no cell reception and couldn't use the phone to call or send/receive sms etc...
I googled a lot and I tried some of the TUT on the web, but nothing helped. Until I found a thread on the xda that said one could try to flash a newer stock ROM (don't know the exact thread).
So I went ahead and checked the version I was on...luckily it was 4.0.4
I then downloaded a newer stock ROM 4.3 for my region and flashed that using ODIN...once it passed I went to recovery: wiped cache and factory reset.
and voila...when I checked the IMEI code again, it was back to the original one.
If that doesn't help check the following thread on xda: here
I suspect he allowed the battery to run out, which corrupted the efs partition, as he says his phone was on 4.3 and didn't change anything until after the problem happened.
Flashing latest stock firmware is the first step, as suggested above, but I think the OP may have to pay for a repair. Make sure it works on 4.3 before you accept the bill.
I forgot to say, my battery got bigger before that happened, i can't fit it in my phone, is double than a normal one, i buy other battery, have this something to deal with the problem?

I was on 4.3 version, i didn't do nothing, i even not installed the root/cwm....the problem appeared from nothing...right before i change my battery. I tried with my region stock rom (4.1.2;romania) and with 4.3 stock ROM but didn't work.
Today i let the phone on a service....i told her what is the problem and i hope there's nothing to do with motherboard. Anyway, please let me know if there's something else to do while i wait 3-4 days for the answer

That's not good...bulging/expanding battery is a very bad thing and should be replaced asap.
Why it happens, is another thing...could be due to various reason such as thermal runaway or even acid leakage.
Fix that first before you move to any flashing and/or other stuff...

Fixed
Hi everybody, i finally sent the phone to service and they fixed it for 17€; everything ok, no problem occurred...i flashed stock 4.3 ROM, then CWM and SU, but....then....after one day of use, i forgot to shut down the phone and, again, removed the battery with the screen on....i connected quickly the battery and the phone started without press any button.....and then, surprise!!! Me trying to make a phone call: "Not registered to network"...fu**...but IMEI was still alright(w t f?). Third day i sent again the phone to the service and they told me that i am playing whit the soft (what man? just because i flashed CWM and SU? damn), i told them again what i do with the battery and they said is not true (now what i am supposed to do? they don't trust me) but fixed it again free..for first and last time. Now here is the question: what i need to back up in case that will happen again? It can't be fixed with a backup of IMEI/Modem file...
Go read the sticky thread in general forum.
