Then I flashed [ROM][JB][4.1.1][VLDLK4] Stock SGS3 TouchWiz ROM / Rooted / Debloated (12/06/2012) I got LTE back. these too roms got huge different speed test result on same servers. Would some one tell me why?

on AOKP and CM10 roms usualy 4G is LTE i found, but when i have flashed roms in past i have had HSPA and 3G so i too would like to know if there is a modem we can flash etc..
also on rogers 1747m thanks

Make sure your APN is correct. Also, it uses Rogers #1 by default instead of Rogers LTE. So that's another thing to look into.
If both those things still don't fix it, you might have to test different modems.

Wind Mobile - Questions

I've been reading a few threads trying to find the answers, but I still have a few questions.
=> Rooting
Looking into rooting my S3 with the "No Tripping Flash Counter" method, however when I click on the download link for Wind I get 3x files. I'm guessing (by elimination) that the one I need is the "root66_GLW_T99VVLALE6.7z" correct?
=> ROMs
I would like to install the "Speed Rom Beta 1", however the thread doesn't indicate what variant of S3 that is for. I have also found in some other threads that ROM's and kernels from other providers should be ok, but then this post on "DONT WANT A BRICK?" is saying that Wind and Tmobile are not interchangeable. So I'm not sure if I can use this ROM?
Thanks,
Vic.
WIND is Globalive, so GLW is the right one for you.
The WIND SGS3 is compatible with T-Mobile ROMs as long as they don't touch the modem because the modems are not interchangeable. Since people have been saying that CM10 and CM9 works for our T999V, SpeedROM should work too since it's based off CM10.

Thanks. I'll give it a try.
Installed and everything is working except Google now (same scrolling issue other user had reported in the thread).
Had a couple or random reboots this morning, but now my carrier signal shows down and I'm getting a prompt for SIM unlock. Any ideas?

aokp with rogers s3

I have read the FAQ for the aokp jellybean release, stated it was designed for the att version but I also found a topic about a member who had trouble with his apn settings on his Rogers phone that was on that rom. So my question is can I flash my s3 with that from?

Which carrier do you have?

FWIW, I am on Telus and have flashed many iterations of this ROM and have had no problems with APNs / LTE / HSPA+.
In fact for the last week or so an LTE option has been available for Canadian users which makes this ROM the best IMO.
EDIT: you could always make a nandroid backup of you current setup and try AOKP. If something messes up just reload your nandroid.

Hello Naruto! I am a happy AOKP-Rogers user, no problem whatsoever and I have been updating to the latest rom pretty much every day. Just 2 recommendations, get Titanium Back up Pro and ROM Manager. They will make your life sooo easy
3G works well for me
Cheers from Canada!

3G working perfectly for me.. try reflashing or do all your cache wipes and dalvik cache wipes... it should work.

New (to me) AT&T S3 on TMobile

Hey guys, I just got a S3 off of craigslist and have T-Mobile service but still have an AT&T ROM so mobile hotspot, nav and other features aren't working. Is there a T-Mobile RUU available or would I be better off rooting it and going with a custom ROM?
So T-Mobile Rom on an AT&T device is ok?
Like they have no problems..
Just being cautious.I'll flash and see one and update you!!

So far I've used the "SAMSUNG GALAXY S3 UNIFIED TOOLKIT V7.0" (http://forum.xda-developers.com/showthread.php?t=1746682) to root and install CWM recovery. From recovery I successfully flashed Jelly Beans build 15 (http://forum.xda-developers.com/showthread.php?t=1973982) and so far everything appears to be working well except for 4g. In the notification area I have "G" and then "3G" but no 4G even in areas where I could pick it up before flashing.
This is an AT&T S3 (i-747) and I used the i-747 image to root/ flash recovery via the toolkit and then flashed the Tmobile variant of Jelly Beans.
Figured it all out. Thanks to this thread I was able to successfully flash a T-Mobile i747 engineering rom (http://forum.xda-developers.com/showthread.php?t=1771021) which also flashed the modem enabling TMo frequencies. Then I was able to reroot and flash a recovery meant for a t999 so in essence my phone is no longer an i747 but a t999 but with a radio that actually supports 4g/ lte. Basically what the new S3 Tmo is launching. My Jellybeans rom which was based off of a verizon build wouldn't allow 4g so I had to replace it with Darthstalker (http://forum.xda-developers.com/showthread.php?t=2014442) which I haven't played around with too much yet but so far is awesome (native tethering works, one of my complaints about other roms). Ah 4G is nice, hit 12Mbps down... So long Sprint... So long Evo "4G"
thank you for the info! very helpful
What area are you, where you get those dl and up speeds? Thanks for the links!

[Q] Stock sgh t889 modem on sgh i317?

I've been using my rooted note to with tmobile for a while, and since I flashed a few roms, I've noticed that my 4g is a bit slower. Instead of flashing back to the att stock rom, I was wondering if I could flash the tmobile stock rom on it. I only ask because the att variant as the tmobile 4g band unlocked already and every rom I've downloaded is compatible with both. Virtually the same phone, so I figured this may be possible. Any ideas?

Can you please add a link to aws dummy zip. I am new in this world. Just bought an unlocked i317 but want to use tmobile sim. While flashing tmobile rom on my i317, it fails at radio part. Would like to try this method. But I could not find aws dummy zip on the net.

Low 4G signal after rooting/flashing CM4.1.2 then to 4.1.3...

Hi all,
I rooted my Rogers S3 then installed with CM4.1.2 last week then updated to 4.1.3. I've noticed since I updated to 4.1.3 that my 4G signal maxes out at 2 bars. So am wondering if the ATT rom that is used has a different baseband file then Rogers? And if so, is it possible to install a Rogers baseband back onto the phone some how?
Thanks...
Pretty sure there is no android 4.1.3 version. And there is a thread with flashable modems u can try...
