Hi, I have got an Auszralian Version (Telstra) of the Galaxy Ace S5830t. This Version supports 850/2100mhz Hsdpa Bands.
However I've been wondering if it is possible to change the Bands using different Modem Firmwares to support 900mhz.
I have already tried the debugging Menu and reading through the existing Post points towards Problems when using undesignated firmwares.
I'm currently running a official android 2.3.5. My current believe points towards the Bands being hardcoded in the Modem and that I might have to buy a different phone
Any help would be awesome.
how can i make my phone work with T-mobile in Usa, i Have unlocked it but i dont know if i can make it work with Data because i have read that it's impossible to make it work with data on 3g. My Phone is S5830L and i have the kp3 modem from telcel.
You need to see the UMTS frequency that T-Mobile uses, I think it's 1900, so, you need to use the baseband for that frequency.
What rom are you using on your phone? You could try this one: http://forum.xda-developers.com/showthread.php?t=1399917
Flash using Odin.
I have a friend who bought an unlocked SIII that supports GSM so he can use it with T-Mobile. However it doesn't have the radios to connect and get 3g or 4g. Will rooting and installing a custom rom or give him this feature? I would think that the hardware supports it but I'm not sure. They do list 3g for AT&T but only 2g for T-Mobile. Here is the phone he bought: http://www.newegg.com/Product/Product.aspx?Item=N82E16875176412
Does anyone have experience with this?
Flash stock rom with correct modem and CSC for your location .
Custom rom will not have correct modem and CSC in all probability .

Hi,
i own a HTC One S (16GB) device, am running a custom rom (MaximusHD 10.0.1), Android 4.2.2, Htc Sense 5.0, rooted, TWRP 2.7 recovery, HBoot 2.16, Radio 1.20.50.05.16, Carrier is Tmobile, supercid 11111111 and bootloader unlocked. i recently installed maximusHD 10.0.0 everything works fine expect for the network connectivity, i can only make use of 2G (edge) signal but i can't switch to 3G only. Whenever i switch to 3G only my networks goes off but when i switch back to 2G it works perfectly please i would be glad if you guys can help me out
You have the official Tmo version or an international version of the phone? That rom is for the international version and might not be set up to properly utlilize the bands of Tmo service 100 is the first thing that comes to mind.
Confirmed: International version of One S does not utlilize any of the bands for T-Mobile past 2G / Edge.
From HTC's website:
HSPA/WCDMA:2
Europe/Asia: 850/900/2100 MHz
GSM/GPRS/EDGE:
850/900/1800/1900 MHz
T-Mobile HSPA/WCDMA uses a combo of the 1900 Mhz frequency and a combo 1700/2100 AWS band.
I don't know if I get you correctly but if this is what you mean my device displays either GSM OR WCDMA so that mean I have the official tmobile version
I'm confused...you don't know if your phone came from T-Mobile or not?
My HTC one s is from T-Mobile, pls can help with the situation would really appreciate it
Ok. When you installed the rom, did you also install another radio or firmware package as well? As in the one that was listed in the OP of the rom here: http://forum.xda-developers.com/showthread.php?t=2445392 ? If so, that is probably why. The rom and radio are for the international version of your phone, not the one from T-Mobile. Now, obviously the phone are so similar that the software works on both versions. The only difference is the data bands that are supported for 3g/4g and the radios that interface with those bands. So, if you have never changed your radio like it was suggested in the thread for that rom - change your rom to one based off of T-Mobile software. If you have changed the radio, then flash one for the T-mobile version, and you should be fine. If it doesn't work after that, you'll just want to make sure both the rom and radio are for the T-Mobile version.
Thanks man, I think I messed up my device and a newbies to this time installation things. I actually followed the instructions given in the maximushd Rom, I flash the firmware packages with my tmobile version device. Pls what can I do to fix this I need your help

Are you S-Off?
If so: http://d-h.st/7V7 - It's a large file with the Aroma Installer to let you pick which radio you want. I believe you'd be looking for the T-Mous 1.13 one. If you aren't S-Off - Don't bother with that.
S-On?
If so, you need to re-lock the bootloader and run the RUU (Rom Update Utility) to get everything back on track, then you can re-unlock the bootloader and redo the recovery and rom stuff. http://www.androidruu.com/getdownlo..._10.30.50.08L_release_309489_signed_ICS_2.exe

Hi, I need help.
So, I bought 2 moto E 2015 model (at&t unlocked) from Ebay - very cheap.
But this phones working with only 2G mode in my country (even theese are LTE models ).
I want to reinstall system to better one - which there is no any at&t default applications or any of carrier applications.
And I also want to change baseband versions - because, this phone working only with 2G network type with my country's mobile carriers. I think it should be for baseband (network standarts) .
is it possible to fix problem with change firmware and baseband to no-contract version?
I asked my mobile carrier, they said, "we are using 900-1800 MHZ for GSM ; 900-2100 for 3G, 2100 for LTE (up to 2100)
Who can provide how to and links?
Thanks.
The AT&T model cannot be bootloader unlocked, so you cannot change the firmware to another version. There's a guide in the General forum about enabling additional LTE bands, you can try tweaking it for 3G, but there's no guarantee that the AT&T model's antenna hardware can support those bands.
