4G Won't Work After Unlock

I have used this method to unlock many Galaxy S3's and Note 2's but recently someone said their 4G doesn't work and they can't get pictures now and it worked before the unlock. This goes for any phone on any carrier, even an S3 for ATT unlocked using that method but still with ATT service still doesn't work for 4G or Pictures. I really would like to get this fixed so I can continue unlocking this phones for free and selling them for more! But I don't want to ruin every S3 I get. Please if anyone knows what I'm talking about or has a solution let me know!

s3 4.1.2 unlock

Samsung galaxy s3 - 4.1.2 updated unlock

--------------------------------------------------------------------------------

As you know those who updated to 4.1.2 the unlock method from the service menu will NOT work , so after a friend came at me today to update his S3 to 4.1.2 i found a method to unlock:

- you will need to root the phone u will find many ways , then install from recovery mode the SIM_Fix_v.0.1 , then install busybox from google play , the use GalaxSimUnlock.apk and voila ! phone unlocked !

If someone needs one of the apps i can upload them !

If someone needs instructions or someth wont work announce me and we will makeit work !

[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] Christian1981:
Hmmm... I did it like this...

Now my phone is unlocked... but losses Internet connection after a few hours. Making phone calls and SMS are no problem... and when I got internet (I mean the fast one :D ) then I have no chance to look a video on youtube or even download an app via playstore! It's kind of funny... tried other modems... other roms... even flashed stock unbranded german firmware (DBT -> as I'm from Austria)... always the same problem...

But when I put in the 'original' SIM, that came with my phone, I get very fast net... but I don't want to use it... in this contract I only get 3GB download and then I must pay for every MB... and with the one I want to use I got unlimited...

What could be the problem?

What can I do, to get it done?

Anyone a hint, a trick, anything?

This makes me ill!

Was it because I got no SIM in my phone at the moment I done this? But in other forums it was written like this...

PLEASE, I need help....

Thanks in advance! :o

Finding Stock 4.1.1 after hotwire's removal

Hi I've given up unlocking the SIM on my S3 LTE by conventional means (I even tried paying for a code, but that didn't work) so I'm going to try this method. My problem is that I can't seem to find a working link to the stock 4.1.1. firmware that I need so that I can downgrade and use the trick to unlock. I found one but it was through hotwire and isn't working any more. Sammobile and samsung-updates both only seem to go back as far as 4.1.2. now. :(

I'm rooted, with stock recovery running 4.1.2. I9305bvbmf1. So I guess yet again I'll lose the root privileges and have to re-root. It was some time since I rooted it and had major problems after a dodgy file linked to CF-Root which massively screwed up what should've been a simple procedure and ended up taking me half a day to sort out. So suggestions as to another option would be appreciated - something reliable!

Also, I know I'm cramming a bit much in here (I might start a new thread if people think it makes more sense?) but would the general consensus be to go back to the stable firmware I'm currently running as opposed to upgrading to 4.3? Are the new additions to the firmware worth the risk or wifi issues etc? I'm due to head to South America in a week or two and stability is a major requirement when it comes to my phone now. I had a HTC HD2 running JB on my last trip and had all kinds of problems with CWM recovery and lots of smaller problems that meant things were no fun for a while!

Cheers!

Hi, here is the stock 4.1.1 for S3 GT-i9305 (LTE) United kingdom (EE) there is no bloatware on this firmware. I found on sammobile

http://terafile.co/e729d5704241/I9305XXALI5_I9305EVRALI5_EVR.zip

flash it using odin, yes you will loose root privilege. just use the instructions given on the first post to unlock your device and after unlocking, update to 4.1.2 or 4.3.

With 4.1.2 you can root, flash custom recovery, custom firmware and anything and you will not loose your warranty (just flash stock firmware and reset binary counter with Triangle away before claiming warranty)

But with 4.3, knox is implemented, you will be able to root (with CF autoroot) but it will trigger knox flag and at this time there is no way to reset knox flag to 0. Thus you will loose your warranty.

About 4.3, no wifi issues for me, everything is working fine, no bugs or anything, battery life is great (better than 4.1.2), charging rate also is extremely fast compared to 4.1.2. If you don't care about warranty just flash 4.3 and root,

Thanks Lucas! I'm in a bit of a rush to get this done as my old sim doesnt work any longer and my new sim only plan has started but I cant use it!

I've already downloaded the 4.1.2 firmware that's on the phone just in case and now I'm in the process of downloading the 4.1.1 from your link (I wonder why I couldn't find that link myself - when I scrolled down it stopped at 4.1.2.) and already have odin installed.

I bought the phone form my Aunt as faulty and got it up and running again so I'm not fussed about warranty.

Would you be so kind as to send me a link to the firmware that you're using for 4.3? I'll give it a go as it sounds perfect for me as my battery life isnt amazing.
[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] LucasBass:
To find older firmware you must head to the firmware section of Sammobile (Do not just enter GT-i9305 in the search)

There will be options like

TYPE OS MODEL COUNTRY, you enter the info and you will find all the firmwares available.

EE i9305 4.1.1

though you have to make sure you have an EFS v1 baseband otherwise your wasting your time, the later efs v2 baseband will not allow you to flash back to 4.1.1

google efs v1 v2 on xda as it is very important
[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] spaceboy_psy:
Thanks for flagging that up! I read up on this thread, just wanted to clarify something: you said efs v2 won't allow a downgrade to 4.1.1, but that thread says 'Stay with the EFS v2 basebands (MG* or newer). You may flash other ROMs but must return to the MG* (or newer) baseband.'

Is that a contradiction, or am I misunderstanding? Suggests I could still flash back to 4.1.1, unlock, and tho that would make my IMEI unreadable at the time, once I reflash to an EFS v2 ROM I'd be good to go. Or is that not right?

Happy to help, spaceboy_psy. Bear in mind that, although this will unlock the phone to all networks, the baseband may still be locked to 3, and you may still have to rely on 3 for firmware updates. I'm not certain of this though. You would have to take that up with 3 when you contact them. It definitely unlocks the phone to other networks though.
[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] daedric:
Don't think so. If the phone is unlocked to other networks then the baseband also is. The worse that can happen, is using the wrong CSC and that causing troubles (rare, but not inexistent).

If you have the Korean version of the S3 (SHV-E210L), I don't think it would work, this only works on the I9305 varient of the S3, do try to flash i9300 or i9305 firmware on your S3 it will possibly be bricked.
