Is ther anyone working on development that would he compatible with the Galaxy Tab from US Cellular? Are any of the ROMs or CWM able to be put on the USCC Tab?

US Cellular Tab Question
I have the same question. I have a Tab for the US Cellular network. It says it's an SCH-i800 for CDMA. Isn't that the same model as the Verizon? Would "stuff" for Verizon work on this Tab??
Thanks for listening!

Ugh, I thought I'd read enough before going today to buy a used US Cellular tab from someone (I'm only using it in WIFI mode, have no need for data connection). Got rooted fine via z4Root but now don't know what else I can do.
I flashed ClockworkMod for Verizon as saw another post that said since both CDMA should work. It flashed but when boot into recovery goes into normal Samsung recovery.
Is rooting as far as you can get w/ US Cellular or can I flash ROMs somehow?

I'm not sure if this is the same as the Samsung Transform, but when I flashed a custom recovery, you have to make it stick somehow, i believe by flashing a custom rom. I'm not 100% so keep reading around the forums but thats how I had to do it for the Samsung Transform.
Sincerely,
D3luSi0n4L

I have a US Cellular Galaxy tab and I just flashed ICS to it and it runs like a champ!
I followed the instructions at [HOLY CRAP][SPRINT P100] Stock to ICS - Complete Walkthrough
I was afraid I would mess it up but it works great now!

Samsung Galaxy s3 4g (GT-I9305T)

hey all, just wondering if the GT-I9305 and the GT-I9305T are the same or not, and whether the GT-I9305 stock firmware is transferable over to the GT-I9305T. :laugh:

Do you mean the Telstra GSIII LTE?
Do you mean the Telstra GSIII LTE?
If yes, then try asking Telstra, though probably they won't give an answer.
I believe they might not be compatible because Telstra has history of modifying models,
both hardware and software, which compromised the phone experience under other carriers.
And assume they are compatible, then why it is named I9305T instead of I9305?
Obviously making one model is easier than making an I9305 and another version with a "T".
So, I guess you probably should not try the firmware for another version of the GSIII LTE until you get a CLEAR answer
Good Luck!

This has been talked about a bit but Yes you can use I9305 firmware on a I9305T. But you need to use a I9305T modem otherwise you will not get 4G reception and some modems no reception

As far as I know they are exactly the same aside from slight software differences. I've got a GT-I9305 bought from Kogan which is a Hong Kong version. In stock form it worked on the Telstra network but the signal strength was not all that great and it use to drop of the network on odd occasion which required a restart in some case to reconnect. I got a bit tired of it so I flashed it with the official Telstra ROM last Friday. So far everything is running great, signal strength is as expected and it did not drop of the network at all since the re-flash.
All I can say now my phone is now a GT-I9305T and it works as it should :good:

awesome, thats great to know.
i was also doing some searching on the internet earlier today and realized that my s3 ( GT-I9305T) was only running the 4.1.1 version of android and that the GT-I9300 was updatable to 4.1.2, i then went on to check for an update which came back unsuccessful saying that i had the latest version of firmware, i understand that they are releasing it model by model but does anyone have any idea on whether the GT-I9305T will get the update? and also any estimate on when?

Thank you

The 'T' in the model number isn't branding. The phone is actually slightly different.
I have a friend who works for Telecom here in NZ and they also sell the I9305T.
He said it is optimised for use on Telecom's network (and obviously Telstra's too) it uses different modems and the antenna is different inside the phone.
They do however use the same ROMs and firmware. Anything intended for the I9305 will also work the same on the I9305T, except modems.

Anyway, Is there a ways not to use CWM recovery and use stock recovery? how can i flash stock recovery and keep root? and if i want to update to 4.1.2, can i do OTA without losing root? Thanking you in advance

Hello everyone!
New to this forum and new to Android phone. I have searched the whole forum and read through the dev-sections. Also did searches on multiple sites and through searchengines to find out what device model to use in the ToolKit...didn't find any confirming answer to my question.
As I have no posts from before, I couldn't write this in the dev-section, so I chose the thread that was closest to what I was looking for.
Question: What is the correct device model to choose in the ToolKit (I have version 7.0.0).
Information from my "about section"...
Phone: Samsung Galaxy SIII 4G
Model: GT-I9305
Android-version: 4.1.1
Build: JRO03C.I9305XXALK5
Operator: Telenor (Norway)
The options I lean towards since the only choice showing 4G, is number 21 (International 4G).
Problem is that it says it's GT-I9305N and not GT-I9305. It also says (Build JRO03C ALIA) and that does not match to my build either.
Then I look at the (International LTE), which says (GT-I9305)...which is ok.
And then number 14, which says (Build JRO03C ALK5), which is the same as mine...but it doesn't say 4G, which I have.
It might sound silly, but I really dont want to make the wrong choice here and end up having a phone that either "does not work at all"
or "does not work as it should". And before anyone says that I then should just leave it alone, my only intention at this point is to let
my anti-virus get root-access, so that the firewall works and the anti-theft works.
Hope anyone can be of help and thanks in advance.

Ok, so I rooted my device yesterday after reading through like 10 more threads...just took a chance, thought to myself "guts and glory" and went for it..went well =) I chose option 14 the build was the same as mine and it worked like a charm.
I am still left with a few quesitons though...might not be relevant to the thread anymore...
Does the rooting share the same build-match requirement as the flashing of a new operatingsystem?
How do I uninstall apps that were preinstalled on an operatorlocked phone?
Anders - Norway

I think you should look for app in app store, Root App delete or something like that. Then search for you operator apps/files and remove.

1. Bootloader is allready unlocked
2.For how to root look here http://forum.xda-developers.com/showthread.php?t=2255190&highlight=how+to+root
3. Flash custom recovery, would advice this one http://www.youtube.com/watch?v=lxZf39vI0Lc. Download the .tar.md5 and flash with Odin in PDA.
4. Go to the CM thread and download the latest nightly and Gapps (Google apps) and place on the sdcard.
5. Go in recovery and wipe cache, dalvik cache, format system and data factory reset and then flash the CM rom and Gapps right after another without rebooting, reboot and you`re done.

hello does it matter that it's a different usb cable, its of htc because the one i got with the phone doesnt seem recognise my phone on the pc

(Q) Very quick question on returning to stock...

I have a GT-I9305T (Telstra Version) currently running CM10.1, I would like to unroot the phone and return it to factory original stock...
1) can I flash a stock i9305 or does it have to be a i9305T based ROM? - where can I get these?
2) should I run triangle away in CM10.1 then flash the stock ROM, and run SU to unroot?
3) after all that is done I still have CWM right? how do I return that to stock?
THANKS IN ADVANCE...

1) Yes you'll need a I9305T based rom, it's to do with basebands and 4G (e.g. i9305 can't do 4G in Australia while i9305T can...)
2) I forget how it is with triangle away, but that's up to you. Whether or not that red exclamation mark bothers you or not. Also it'll automatically unroot when you flash the stock rom via Odin. So no worries about that!
3) CWM will be removed (stock recovery restored/added) and any custom kernels will be gone too.
Good luck, but becareful with Odin. If you don't feel certain about something, look it up on YouTube (as their explanations will be better as you'll be able to view it).
Hope this helped

thank you

there's a button for that

He wants to unroot and go back to stock, he is using a T model.
Research before you come and talk...
"The I9305 is the European version and the difference is:
The I9305 operates on the LTE800 & LTE2600MHz bands
The I9305T operates on the LTE1800 & LTE2600MHz bands
Therefore the I9305 will not currently operate in 4G mode in Australia (will only operate in 2G or 3G mode) as Australia is currently using the LTE1800MHz band (both Telstra & Optus).
If you are living overseas and want to visit Australia, then the I9305 will work (not at it's full potential though). If you live in Australia buy the I9305T."

In-case you meant he just needs any old rom for i9305 and just flash a modem for the T. There are from what I understand a complete different line of stock roms for the T version. Just simplify it and let him flash the official stock for the i9305T, if you want to go into details feel free to. I offered help and gave him a valid answer.

Get a life and stop trying to answer an already answered question.
Good day to you sir...

I live in Australia and have both t and international versions. Both work on 4g. I stand corrected if he wants to go back to stock on t version.
But you are wrong about the T version only doing 4g here. Both t and non t work perfectly here and you can use either rom on both its the modem that's specific that was my point.

The thing is, you're stating that Telstra themselves lied when they said using an i9305 Rom/firmware package is not something that is recommended and hasn't been tested.
They also said that there is a difference...
Also, they way you came and said that was 'bull' was childish and plain rude.
I answered the question correctly and showed facts.
You've done nothing but call part of my explanation 'bull' and nag about how there is then no difference when clearly there is.
Next time I recommend you be more friendly when claiming someone is wrong.
I recommend you leave it at that, cause I am.

Can Europe GT-I9305 run with Telstra Rom?
Hi,
I have a Galaxy S3 4G GT-I9305 bought via Kogan. Came with a French splash screen.
I currently am using Telstra but have rooted the phone and running Cyanogenmod.
I want to unroot the phone. Can I use the Telstra GT-I9305T rom? Will it work or is the modem different?
Thanks

Get a life and stop trying to answer an already answered question.
Good day to you sir...

"Unfortunately Jupiter you have been misinformed. Optus provide a 1800mHz LTE network and sell Samsung I9305 handsets to use on this network. The I9305 will also work on the Telstra 1800mHz LTE network.
Google is your friend. Try these links for some light reading and education."
Maybe you should have read the thread you linked to a bit better you arrogant clown, the above was the last post.

I know this is bulls#@t because I have the optus GT-I9305 not the I9305T, my girlfriend has the I9305 on optus too and we both get 4G.
Pull ya frikken head in and don't shout someone down when you appear to know sfa about the 4G networks in Australia.
Yes, to go back to stock the I9305T rom is needed for the OP but saying that the I9305 WON'T get 4G in Aus is complete and utter crap.

yes I'm sorry about that, I was just intimidated at first since I thought there was a significant difference between i9305 and i9305t

I have the same phone, GT-9305T from Vodaphone & flashed the Galaxyrom ver 4.1.2. Had problems with an earlier Galaxyrom 4.3, Ver 12.1 but Camera app has problem There are fixes available but haven't tried yet. Will try again with later release but for the moment I'm happy with 4.1.2.
Everything works & Aussie Developer so feel more confident that the rom will fit aussie phones.
