Is their any mods for the radio part.... reception / transmission?
Also
Is their any mods for increasing modem speed/dl and ul speeds?
Also is it just sprint radio i it or unlocked it and sprint and all other bands come or is it just sprint?
What about art and T-Mobile versions with 1.5g dual cores on them?

I'm new here and I enjoyed this site very much. I have one problem with my TP2. Somehow, 3G network is not working after I installed Hard-SPL and unlocked T-Mobile TP2 switch to AT&T sim card. Everything is working fine with AT&T's sim card I was able to made phone calls, received, SMS, and web browsing. ATT 's 3G network is available around my home, but I can not get 3G on TP2 instead a EDGE network. Can unlocked TP2 handle AT&T's 3G network? or a .cab file I can download to fix this?
idk for sure but i think t mobile uses a different frequency for 3g from at&t so if they are you are stuck with edge speeds on at&t man sorry
I have the tmobile TP2 and i can confirm from talking with ATT that the phone does support ATT BUT i was unable to use the phone on 3g. The phone DOES support the signals for 3g but am still unable to access the towers in my area. I think the phone may be hard set to look at tmobile towers, is there any way i could reset the device to open up its tower usage? Hopefully i can get an answer but no tmobile TP2 users arent screwed in the US we just need to find a fix
It was my understanding that the tmobile tp2 does NOT have 850/1900mhz 3g on it. It does have aws 1700 for sure. Not sure about 2100mhz though for overseas.
This issue has been covered many times in the numerous AT&T threads on this board.
I'm sorry to tell you that the T-Mobile TP2 hardware radio was limited to using 3G over the 1700/900Hz frequencies, while AT&T currently uses 1900/850Hz only. It's unlikely that any change can be made to the radio software wise to fix this issue.
Just to make things clear the issue has nothing to do with Hard SPL or custom roms.
T-Mobile UMTS 1700/2100 Mhz
T-Mobile 3G runs on UMTS 1700 up and 2100 down. Unless you have a device that runs on those specific frequencies, EDGE is the best you can do with T-Mobile if you opt to run on their service.
ATT offers UMTS or 3G using 850mhz(the old TDMA band) and 1900mhz. While T-mobile offers HSDPA (technically 3.5g part of the UMTS specification) using 1700MHz for uplink and 2100MHz downlink.
Because HSDPA is part of the UMTS spec, it’s backward compatable. However, you have the limiting factor beging that the frequencies the individual carriers use to transmit the data.
Europe and Asia’s 3G runs on 1900/2100mhz. North and south America is supposed to use the (AWS) 3G spec using 1700/2100mhz
ATT didn’t want to wait, like T-mobile is doing, for homeland security to vacate those frequencies and launched on 850/1900mhz instead

I heard that t-mobile did not have enough spectrum in many areas to launch 3g in its existing 1900mhz. At&t doesn't have that issue, or as bad.
Im gonna make this real easy for u. The tmobile tp2 will not work on at&t 3g. The 3g bands are different
when I go through the specs for the AT&T and Tmobile variants for the note 2, I come across a difference in the following
AT&T,
GSM Quad-band: 850/900/1800/1900 MHz
Tmobile
Frequencies and Data Type GSM Quad-band: 850/900/1800/1900 MHz UMTS: Band I ,band II, Band IV (Dual-band1700/2100 MHz), Band V
What does the dual band mean? Is it for Tmobiles 4G network?
I thought all the Note 2's in the US had the same LTE radio
please shed some light,
thanks
1700 MHz/2100 MHz UMTS (WCDMA) AWS is currently T-Mobile's 4G network.
T-Mobile will have LTE up and running sometime within next year (2013).
Yes T-Mobile Galaxy Note 2 devices do have LTE. But it is now not activated. T-Mobile will activate the LTE within T-Mobile's Galaxy Note 2 when they get their LTE service up and running within your area.
How to activate the LTE and running on another carrier is a good question. This I get bits and pieces. But not a full step-by-step process yet.
The T-Mobile Note II is pentaband; it will work on AT&T and T-Mobile 3G/4G (not LTE though as of now). I think that's what you're getting at.

I believe that we can get the LTE up and running with other carriers. I know that I got LTE working on my GN2 (SGH-T889). We just need to learn how to get the LTE running with other carriers. That is really the question. When we figure that out then this might be able to be applied to other GN2 devices.
Tmobile hasnt turned on lte yet. From what i understand once they do our note 2's should be able to utilize it.

Tmobile uses 42.2 mbps dual channel hsdpa.
Afaik, At&t uses 21.1 mbps hsdpa.
Lte(long term evolution) is a different technology not yet active for Tmobile customers.
Real World, my friend with a Galaxy nexus on Tmobile network gets about 8mbps while I get 14mbps. Galaxy nexus has the 21.1mbps capable modem.

You're talking about something called DC-HSPA (Dual Channel/Carrier), which is basically what you said: Using 2 frequencies of HSPA(+) to achieve basically double the throughput.
Is it a hardware limitation (as in slightly modified Qualcomm LTE Chipset) in the AT&T Note 2 that 42mbps is not supported compared to T-Mobiles version? Or it is software / firmware-controlled?

It could be software (on the modem level, which is low-level stuff and separate from the ROM); T-Mobile's Galaxy S II was basically AT&T's Skyrocket with LTE disabled. You could actually flash a T-Mobile S2's modem onto a Skyrocket to get it to work on T-Mobile frequencies (but you can't get LTE enabled on the T-Mobile S II as far as I know).
would you say the note 2 from verizon is any better since it also includes a CDMA radio? Also, though LTE only works in the upper 700 frequency, any change a modem update or firmware change will allow the verizon version to work on T-mobile or AT&T network?

No; CDMA is useless unless you're going to be using it on the carrier it came from. I'd say the T-Mobile version is the best (in terms of working with the most networks), then the AT&T version (because it has LTE), then the International version (because it's the AT&T version without LTE), and after that the Verizon one because Sprint are jerks because they use "embedded SIMs".
So... our AT&T Note IIs have the same chipset for the 3G radio as the International LTE ones... right? Does that mean we're theoretically capable of Quad-Band 3G like the International LTE ones? or more?
Bump?
Is there a way to use Verizon HTC ONE with T-MOBILE with data speeds other than EDGE (E)? Is there any other methods like flashing a T-MOBILE radio (don't know even if that is possible). Would any MODS, developer or expert with insight to the hardware provides inputs ?
Thanks and Cheers!!!!
PS - I have seen other threads just cutting short to sell this phone and buy another one, I am trying to see if there is another solution
If I'm correct the reason why the device does not work on T-Mobiles LTE network is because T-Mobile runs there faster network on there 1700mhz band which is only supported on the T-Mobile variant of the HTC One. They have acquired some 700mhz spectrum from AT&T after there botched merger and have been using that spectrum to release some of the stress from the 1700mhz band. I have heard of it working on the the 700mhz spectrum but not the 1700.

Thanks for the info
If the hardware is compatible - would it be possible to flash T-MOBILE radio onto Verizon ONE?
The hardware is compatible its just that it does not have the compatible radio to work with their LTE/4G band to get data. It will get Edge no problem and the areas that are running on the 700mhz band but that's it.

Will I lose any lte band support if I convert to tmobile?
Yes, flashing T-Mob US (I assume you mean US, since you are talking AT&T) firmware or RUU will change band support, and you will lose some LTE bands.
According to the specs on GSMarena, with the T-Mob firmware, you will have support for LTE bands 4 and 17; and will lose support for 2, 5, and 7.
What bands do you need, and what carrier are you using?
Tmo USA
What if I merely flash a tmobile based rom

Just flashing the ROM, you won't change the band support.
But again, I'm curious what carrier you are actually using the phone on?

Should work fine.
Being on T-Mob US, and using AT&T radio baseband (part of the firmware that determines band support) should be fine for the most part. Reason I say this is:
1) ATT radio supports the same LTE bands as the T-Mob radio (4 and 17), and then some.
2) ATT radio is missing HSPA (3G) Band 4 (AWS). This used to be the band most widely used by T-Mob for 3G. But my understanding, is that they are well underway in migrating 3G service to 1900 MHz (Band 2) which is supported by the ATT radio.
3) The only "negative" to staying on the ATT radio, that I can see, is that if you happen to be in area where T-Mob is still using AWS for 3G , and you don't have LTE service in that area, either. In that instance, your data will drop down to EDGE (2G). I don't really have an idea of how widespread this situation may be; but I have a feeling its relatively small.

Yea thats why I got an unlocked ATT m8 instead of a tmobile one for the extra lte bands. I have yet to run into band 2 lte and all the aws hspa has been reused for lte. Luckily.
