Root Note Data Woes

I posted this in XDA Developers too, but I didn't get any good answers... So, I thought I'd try here, too.


Ok, just a disclaimer (I am well-aware of my n00b status here)... I spent quite a few hours already on this site and on the Android forums, and on Google searching for answers to this... Not to mention time at the AT&T store and chatting w/some other phone reps (including Samsung tech support and AT&T tech support)... And while I've made some progress, I still can't get any definitive answers here.

So... that being said, first (and big 'sigh' I'm sure to many) is that I'm using a South Korea Note - the SHV-E160S. I know this is the I717 forums, but before I get flamed and booted, let me explain...

Well, I am on AT&T. No problems with calls or texting (minus the annoying 80-character limit, but anyways)... However, I have a BIG problem with the LTE. I'm on the LTE data plan, however, I cannot access any data network other than GPRS. Yes, my pings take about 533ms. My download speeds are about 53kb/s. This sucks, quite a lot. Esp when compared to my fiance's Note, which side-by-side gets about 13mb/s on the LTE network.

So... Did some research, and got the run-around... Less all the crap I heard from AT&T reps... It seems that the antenna for my Note is set to LTE850/LTE1800, and the actual AT&T SGH-I717's antenna is set to LTE700/LTE1700/2100. My sources for this come from PDAdb.net (I'd hyperlink, but my post count is not high enough to do that, yet).


So... Here come the questions. First... Is the antenna frequency tuning something built-into the hardware, or is it something that can be tuned via software?

-If it's in the hardware, would it be possible to buy an AT&T-spec LTE antenna? Which antenna gets replaced (from what I understand, there are two, and I can't find a legit source that tells me which is which), and where could I buy such a thing?

-If it's in the software, what would I have to do to re-tune the antenna? My phone is rooted with the latest Gingerbread Tegrak kernel.

Lastly... Though there is a difference between the LTE antennas... I still cannot access any network other than GPRS. I should at least be able to access EDGE, UMTS, HSDPA, HSUPA and HSPA+ as well, but I can't.

If ALL else fails, I guess I could get a portable tethering device with a contract... But that'd be oh-so-annoying to have to carry around all the time, and I'd like to avoid that option as much as possible. I'm paying $30/mo for LTE service on my phone already!


Anyways... Any thoughts or advice would be very appreciated, and my apologies if anything here is out-of-place. Thanks in advance!
 
Welcome to Android forums!:)
I am not going to flame you, or boot you! ;)
Why on earth would anyone do that?

I did, however, move you to the "all things root" section of the Note LTE forum, since you are rooted. I realize that your Note is not the LTE version, but there may be some tech wizards here that can help you turn it into an LTE version.
I am not one of them, unfortunately.:o

If we leave your thread in this forum for a few days, and no one can help here, we can always move it into the International Note forum.
Good luck!

The international version using a quad core chip that does not support LTE.
The att version uses a dual core chip that has LTE support.

There is no possible software to do so.



Did you check your APN settings and verified they are correct for ATT?
Does you MMS messages work?
Did you try swapping swim with your wife to see what they both do?

Im pretty sure the koreans have a quad core LTE device that works on a different frequency as the us does. My best suggestion would be buy a new phone...

It's not the international version... It's the Korean version, and they all (SK Telecom, Olleh and one other one) have LTE. Which is why I asked if it were possible to swap antennas or change the tuning of the LTE frequency. From my sources, I read my Note is set to LTE850/LTE1800, and the actual AT&T SGH-I717's antenna is set to LTE700/LTE1700/2100.

The APN settings have been gone over a million times... First setting them all to the same as my fiancee's Note, and then I tried some for HSPA+, and nothing got me anything other than GPRS. MMS does not work.

I haven't tried swapping SIMs... I'll give that a shot.
 
The Korean note may not support the LTE bands...that seems to be the consensus from what I have read (which is not much)


In a situation like this (I noticed recently on XDA a few are having this issue) it honestly may be better to unload that Korean version and grab one that has ATT LTE bands.
