Hey guys, here's some possibily stupid question. I have a brazilian P920H and my 3G carrier operates at 850MHz where I live.
That being said, there's simply no way that any P920 firmware will get 3G network on my phone, but all GB options I have available are haunted by some ghosts... I'm stuck at froyo for the time being.
It is known that the european basebands works with P920H, only lacking support for some especific frequencies (including WCDMA 850MHz), but is there a way to add this frequencies to the basebands of the GBs that are free of ghost calls? I simply don't know anything about programming, so my question can be dumb as hell, but I guess it won't hurt to ask, right? =D
Maybe there's just some stupid file saying wich frequencies the radio can try to operate, or maybe there's a whole bunch of code for each frequency. I simply don't have a clue, so I awayt for the expert's answers.
Thanks.

So it looks like TMO is using 1700/2100 for 3G while AT&T is using 850/1900 MHz. So basically the Dash3G is useless on AT&T for 3G.
Does anyone know if flashing the radio part on the Maple with one that has the correct frequencies will enable 3G on AT&T's network? Or are the radio frequencies a hardware thing? I know the SNAP S522 is the true USA version with the correct bands I just have no way of getting my hands on the radio partition.
I want 3G on my Dash"3G".
Firstly - thanks very much for all the ROM's and your hard work!
I'm a long time browser of these forums, but don't post much. Also a long time user and "flasher"!!! All the way back to the old MPX200 days. Always liked WM Standard, so it's realy good to see all this interest!!!
HTC seems to have been real cagey in their frequency descriptions when it comes to the Dash 3G series of phones. I read somewhere that there are software driven transcievers in some obscure phones out there......and I wonder if HTC actualy did this with their latest and greatest....
Just thinking out loud, per your question. When you look at the spec sheets, they seem to be "non-commital with regards to wcdma specs.
Hmm.
Also, it'd be good to have a set of radio only ROM's, as and when we see T-Mob USA fixes.. there needs to be some improvements made with regards to switching between edge and wcdma - in my opinion. I'm in the DFW area and get dropped calls, the phone drops to edge way too often, especially after a call.
Although there are multiple threads regarding the radios that can be flashed to modify the i727R to work on the aws frequencies, I've been having a hard time finding the right combination of kernel, radio and ROM to get my GS2 to work on mobilicity
I would really appreciate if you could post the following if you have your phone working on AWS
ROM:
Kernel:
Radio:

Thank you for your input
Wrong thread to post this. Need to be in the Q and A section. Soon to be closed and u will probably be flamed a little before hand. Good luck.

Bro gonna says this real nice Google is your friend. took me 2 seconds to find the answer don't be lazy search!!! here is your answer:
Mobilicity is running a 3G AWS HSPA+ network.
Meaning only 3G phones with AWS frequency bands will work on their network.
Rogers is using AWS for a 4G LTE network.
Yes, the same frequency bands, but it different technology all together.
It will not work.

It'll work, you have to flash the t989 modem to enable aws for mobilicity/t-mobile

No need to flame, but Rotary Parts, before u call out others always make completely sure you are correct, or like in this case, end up looking uninformed.
Skyrocket is one of the first android smartphones released with a pentaband radio that was lte capable. In essence, this means that it will function on any gsm network worldwide, assuming u have the correct radio firmware installed.
OP, kernel/rom/radio combo doesnt matter. As long as u have them all gb based, or all ics based, they should work no problem.
Just make sure u flash in this order
1) Rom
2) Kernel
3) Radio
if i flash the newest cyanogenmod on my skyrocket, is there a matching kernel i need to flash on it after? I flashed cyanogenmod and then the radio and for some reason on wind mobile i can hear incoming audio, but outgoing audio to the recipient is all garbled up. I've tried just about every radio i can find and none seem to work.
[Q]
Alright guys I need some help.
I have a Huawei Ascend G300.
Model Number: U8815
Android: 2.3.6
Baseband Version: 109808
Build Number: B895
Not rooted.
The phone specifications say that it supports 3G 850MHz,
but I get almost no signal using a 850MHz network.
I believe it is some sort of restriction placed by firmware maybe.
Might need custom rom or something so I can actually use the phone.
Any one can give me any information regarding this?
Thanks in advance.
What I should say is that it only works where there is 2100MHz reception (very few areas)
but I want to be able to connect to the 850MHz band that is available everywhere.
That involves the radio part of the firmware,which 99% people don't change.It's better off if you don't change it too.It's highly unlikely that they would wantedly block the reception of the phone,and its even more unlikely you'd have someone who has created a custom stable radio for a Huawei.Have you considered that the 850Mhz signal might be weak in your area,or that your phone's hardware might not be good at receiving it?If you're sure it's not either of these issues,your best bet is to restore it to factory defaults,or reflash the original ROM.

The phone has the original rom and is not rooted.
gsmarena.com/huawei_ascend_g300-4594.php
The phone specifications say that it supports both 850 and 900 bands.
I live in New Zealand where Vodafone operates on the 900MHz range.
The alternative provider Telecom operates on the 850MHz range and has full coverage throughout the country.
Given the specifications of the phone I can only conclude that either the firmware restricts use of a non Vodafone band
or that the phone is locked to Vodafone (however im pretty sure the phone is not network locked)
If anyone has this phone and is using a 850MHz network, I would like to know what firmware etc. they are running.
Thanks again for the help.
Hi Guys,
So I've been running Clean Rom for roughly 6 months now, still running version 5.1 (Android Version 4.0.4) on my HTC ONE XL.
My One XL is a Telstra branded phone and thus has the capability for 850MHz. I was running on the Vodafone network and therefore not using said band, however I have recently swapped over to Telstra (Was never with them in the first place).
Unfortunately I'm not seeing the gains in reception I was hoping for, and I am currently finding that when going to locations where there should be signal, albeit edge, crappy signal, I am receiving none. My question is, does Clean Rom disable the 850MHz frequency or does it still support it? Is there a way I can check whether I am accessing the 850MHz network, and if so, how? If it isn't am I able to turn on th 850MHz frequency?
Looking forward to getting this sorted. Cheers.
ROM shouldn't make much difference in band compatibility. Since your version supports 850 MHz for both 2G (EDGE) and 3G, it should work regardless of ROM, and you don't need to "turn it on". There are "secret codes" you can enter into the dialer that will tell you information about the bands, and also signal strength. Just use the XDA search function, and you should be able to find them.
You might see some slight improvement if you are not currently on a Jellybean radio, and flash one (if hboot 2.14 or higher, you will need to s-off). But I wouldn't bet on it making a huge difference.
What makes you think you should have (crappy) reception in the mentioned locations? From reception on another phone? Every phone is different (antenna design, etc.). Since you mentioned the reception at the location is already crappy, its probably more of a antenna issue than a ROM issue.

I'm not sure where you're located, Telstra is the largest Telco in Australia with the largest and best coverage. Vodafone unfortunately has a very bad reputation for reception. Swapping from Vodafone which does not use an 850MHz band to Telstra, which does, has netted me reverse effects. I am receiving worse reception, which should not be the case. If I go into fringe areas where edge is the best signal you receive, I will receive none, where as in town locations where more than the 850 band is used, I receive okay signal. Just seems like I'm not picking up the 850 band.
As I already mentioned, search for the "secret" dialer codes. There are codes that will tell you the cell tower signal, and I believe band, which sounds like what you need.
None of the dialer codes seem to allow me to see what particular frequency I'm using. Unless I'm just completely missing something? The only thing that seems to provide me with info on the radio only states Network Type and the DBM.
Hello XDA! Longtime lurker, first post.
I've got a Korean LG G3 and T-mobile service, which means LTE and 2G bands are off limits in the United States. I'm running CM12 as of a few days ago - when installing the new OS, I flashed a new radio baseband as well. It included an HSDPA band that I'd not seen before.
As a n00b, I'm confused as to where hardware becomes firmware becomes software. I've read many a post on the forum, but confusion remains. From this post it sounds as though with some patience and method, modifying my phone's firmware to include additional bands is possible but putsy.
In the case of the G3, there is a variant for each major US carrier. The T-mobile variant is the D851.
The question: can I flash the baseband radio/modem of a D851 onto my F400L and gain access to T-mobile's entire frequency set?
If you could point me in the right direction, I'd be much appreciative. Thanks and cheers.
