[Q] Unlocking + Signal Issues post Flash and IMEI fix - Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help &

Hi All,
I've trawled through this forum for quite a while and haven't yet found any answers or similar cases to the issue I'm currently having. Here's a summary of where I am at the moment with my i9305 LTE:
- Got a i9305 locked to EE.
- When EE quoted £20+ and 10-20 days for unlock I started looking at altenatives.
- For one of the alternatives, I flashed to get root and I believe I lost my IMEI. I didn't have an efs backup and was unable to restore via stock flashing.
- Luckily, I had a screenshot of my settings so I re-wrote my IMEI using QPST.
- Decided to go for the legit unlock this time so called EE and paid for the unlock code.
- Pre-root, when I put in my unsupported SIM I would get a prompt for an unlock code, but that doesn't have anymore. While waiting for the EE code, I found that when I inserted the unsupported SIM, I would sometimes be able to connect in very specific locations (e.g. certain places outside the house). Wi-Fi works perfectly.
- When the unlock code came, I attempted to enter it by getting to the prompt using "#7465625*638*#". Although, when I enter the code here, it does not accept it (I have an unlock and an unfreeze code, neither work).
- I have trialed the SIM in various other phones and have had no problems with signal at all, the problems arise when I place the SIM in the i9305.
- I have tried changing the modem, so far no luck...
No idea how to go about fixing this... At the moment I can't use it as a phone.
Here is some more info:
Samsung GT-I9305
Nameless Rom 5.0.2
Baseband: I9305XXBLL3
Android Version: 5.0.2
- Should I keep trying different Modems?
- I've tried to verify whether phone is locked or unlocked, but *#7465625# doesn't work, do you know any other ways that I can diagnose sim lock status?
- Will different ROMs or kernels help?
Thanks for any help!
-- UPDATE --
Have flashed back to stock 4.1.1.
I attempted to sim unlock via the *#197328640# approach, but wasn't able to get it to work...
My current next hope is to try and restore my i9305 to the point where it asks for a code to unlock upon entering a new SIM again... Would really appreciate any help, Thanks!

I've still not been able to fix, but will update when I do in case it helps anyone else :good:

[Q] [Help] Upgrading to I9000XXJPC via KIES/ODIN ORANGE branded set locked.

Hi all.
My wife has an Orange branded Samsung Galaxy-S and she was complaining about the lag she was having. After applying the One Click Lag Fix she wasn't too satisfied so I decided to look into updating it to one of the Beta Froyo ROM's and found the following guide: http://forum.xda-developers.com/showthread.php?t=769400 (I now know this isn't the latest version of 2.2 for the Galaxy-S and that the guide is old!)
I first attempted to do so via KIES which left me in a Force close loop of Touchwiz and other apps so I then flashed via ODIN which was successful except my wife's Galaxy wasn't accepting her Orange sim as the simlock had changed.
I then looked into my efs folder to find that my nv_data.bin and the backup were recent (I assume this is because of the two flashes, KIES and ODIN) and my original data.bin is lost.
The only thing holding me back now is the unlock code (it was unlocked before) and for some reason I can't generate an unlock code as it is now.
When I replace the older nv_data with the newer one the phone reboots but with a generic IMEI but no simlock. When I use the older one, the phone has the correct IMEI but the sim lock is present.
Is there any way around this at all? Would a paid IMEI unlock code be possible to get around the sim lock? I'm not sure if such a thing even exists.
Any and all help appreciated.

Apologies if this is too similar to this thread. That does sound like the same issue as I am having.
More info: According to SGS Toolbox, my current nv_data.bin has a product code I9000HKDORA which I believe is the correct one for an Orange branded handset. Does this mean this could be my original nv_data.bin?

I did try that first of all and that's when I lost my IMEI number.
I've now turned on my wifes Galaxy with my Orange sim in it and it seems to be recieving texts. MY sim works fine in my old SonyEricsson phone (calls and SMS) but the Galaxy won't do anything as it keeps asking for an unlock code.
Thanks for the reply!

Support Request - Network Issues

Hello,
I recently purchased an i9305T 2nd hand but I am continually getting network errors with my Vaya (Optus) Sim.
I have not been able to get mobile data to work at all, using various configurations.
I have tried flashing a custom rom (CM Nightlies) and flashed various modem packages but still the same problem. I can send & receive texts and calls for a few mins, but then it comes up with network unavailable and nothing will work.
I'm not sure if the phone is locked, and at one point I figured it was locked so I purchased an unlock code but I can't use it as I am unable to use ANY USSD codes (I have tried heaps) except for the one to check my IMEI (Which is fine).
PLEASE HELP ME!!
Thanks,
try flashing THIS
is a Modem/Radio for your contry(Australia)...if this doesn't work try flashing the firmware for your contry(get it from samfirmware.com)...
if even this doesn't solve your problem it means it's a hardware problem...not software..

Blcoked or Bad downgrade?

Ok a friend of mine brought me a i9305 lte to unlock as i have done several of my firends. so i did these steps
1. made a back up from QPST
2. Cf auto rooted
3. installed custom recovery
4. downgraded to 4.1.1
5. did the network unlock from service menu
i then put my sim card in but kept getting not registered on network. i tried setting service provider to auto and also selecting manually and it does the same but no longer asks for sim unlock code so i assume its now unlocked and has some other problem. i thought it may be a imei issue and checked but the imei is fully there and matches the one behind phone batter it also has the correct baseband.. i checked in the about phone menu and it says network unknown and out of service. thinking it may be a radio issue i proceeded to install a stock 4.3 that was originally on the phone from the network carrier it was originally locked to, to see if it was a radio problem but again get network unknown. so i restored the QPST backup over the stock 4.3 and it still says network unknown.
I am starting to think the phone may be blocked but not sure as i also hear its a common problem to lose imei and / or service during rooting. Am i missing something pbvious or fighting a losing battle lol..
one other thing of slight note is when i went to sammobile for the stock rom, when i was searching i searched for i9305 as thats whats on the sticker but it has a little badge on the back that says LTE which according to sammobile is the i9305N and i9350T.
thanks for taking the time to read this and the help you guys allways offer :good::good::good:

Unlock SIM card problem (MMI code does not work)

I'm having problems when i try to unlock SIM card. when type 2945#*880# i get the error "no network or incorrect MMI code" (or something like that). i tried typing many other similar codes but none of them works. currently i'm using aosp 5.1.1. custom rom, and i tried also on cyanogenmod rom, but i get the same error.
i have read somewhere on this forum that cm doesn't have hidden menu, but i cant find original preinstalled ice cream sandwich rom anywhere.
can anyone help me to unlock sim card?
my service provider gave me the code for unlocking, but i cant access the option to put it and do the unlocking.
is it maybe possible doing it with adb?
You really need to go back to the last official ROM to apply the SIM unlock pins from your carrier. If there is really no way around it to go back to official ROM, then you can try your luck with the last Euro-open LG v20c JB ROM. I can see the UnlockMenu.apk is still there, but I am not sure if it will still work on non-carrier ROM.

LOST IMEI - Please Help

I did something really stupid and ended up with a bad flash on my NOTE 9 - the result is that I no onger have an IMEI number on my phone - no data at all - no mobile data.
I know what my IMEI Number is from my GOOGLE account - but I don't know how I can fix my phone to get the IMEI number back into the phone.
Any suggestions are grealy appreciated.
I did a google search which had a few suggested ways using the dialer - but when I attempt to do that, nothing happens - I don't get any result from the dialer codes online.
Your help is greatly appreciated
Find the latest software for your phone and install it with Odin. Or emergency software recovery with Smart Switch.

For the benefit of others (to hopefully not make a similar misstep) what did you do to create this issue? Flash a ROM from another region, carrier, etc.? I understand if you prefer not to share... thanks for the consideration.

There was a rom in the Custom Roms section that looked like it was meant for our phones - I think it was the WETA ROM - I didn't read the oP very carefully - totally my fault - it was not intended for the N960F - (but that was not really that clear when I first read the OP - or at least I lverlooked it. i will be much more careful next time. - it damn near bricked my phone.
I tried flashing full firmware in ODIN to fix it -no good - the flashes failed. - I tried restoring Nandroids - they restored fine but IMEI was still missing.
The fix I found eventually was to flash the DEV BASE Firmware that was recently added to the Roms section - flashing that fixed my issues and I am now back and working properly. I tried more fixes than I can count - and all of them failed - I was close to thinking I might have to buy a new phone. Dr Ketan suggested I flash the Dev Base sortware and he was absolultely correct. It worked.

Neither Option worked for me - ODIN Flashes got stuck halfway thru the flash - and Smart Switch just didn't work

Glad to know you're good to go... i just received my Dual Sim Note 9 today and got it setup to work with ATT using an ATT CSC and used it for 20 minutes. Popped my T-Mobile SIM in the phone and blam! got an invalid SIM card message followed by a SIM network PIN blocked. Enter SIM network PUK message. Got PUK unlock codes from ATT and T-Mobile and they did not work. off to do more research....

I was able to get around the PUK code through a master reset. Go figure.
There's a thread in the forums that talks about copying your carrier's CSC to your phone and then making the necessary changes to four files in the /efs/imei folder. It's not hard, but you got to be very careful. Instructions are in the thread mentioned above. I have LTE/HD Voice access during phone calls, but I have not been able to get Wi-Fi calling to work because the IMS service FC's when launching.
I suspect it may have something to do with using a dual-sim phone. I have both my AT&T and T-Mobile SIM in the phone, and I'm loving using one phone for business and personal calls. I also have Google Voice and I can use that for Wifi calling if necessary. As a final note, to get access to AT&T enhanced services on a non AT&T phone, you have to use an IMEI number from an AT&T phone that supports its enhanced services. In my case I've been using the IMEI number from my three-year-old Samsung S6 active. I called support told rep that I was using my S6 active while waiting on a new phone and they associated the IMEI number with my cell number.

I have an IMEI number from a Note 9 that was an aTT Phone - I had purchased the snapdragon varient at Best buy and then returned it when I got the N960F . I copied the IMEI number before I turned it in - I suppose I could use that. Can you offer a link to the thread you are referring to?
thanks for the tip my friend.
