[Q] 3G problems

I just got a nexus one last night. it was previously used on ATT and now i'm using it on TMobile. I noticed right away that it would not connect to 3G, only 2G. today I rooted it via rageagainstthecage and adb because it was already updated to 2.2.1. I was just wondering if anyone else had this issue and what can I do to fix it? Do I need to fix the radio or what? The specs of my nexus one are as follows:
Version: 2.2.1
Baseband Version: 32.36.00.28U_4.06.00.12_7
Kernel Version: 2.6.32.9-27240-gbca5320 android-build(at)apa26 #1
Build Number: FRG83
I experienced these issues even before rooting. I really appreciate any help.

Hi,
When I upgraded to Froyo on my N1 I didn't have any 3G, turned out 3G was disabled, I re-enabled it by going to the phone dialler and type in *#*#info#*#*, go to phone information and scroll down to the bottom, should be set to WCDMA preferred.
Something to think about as well, I recently upgraded to 5.08 radio since 3G was very patchy since moving to Froyo, works amazingly well for me, seems hit and miss for people but well worth a try at least.

how do i upgrade to that radio and will that work in the US?
also, i did the dialer thing and it is on that preferred one already, is there anything else i can do? or should i change it from that preferred one?

You can grab the radio from here http://forum.xda-developers.com/showthread.php?t=723839
It will work for all Nexus Ones, make sure you have your phone fully charged before you do this as a failure while flashing will brick your phone. There is a couple of ways to flash it. I used fastboot, you just extract the zip file which contains radio.img, then do the following command, fastboot flash radio radio.img

ATT and TMO use different 3G frequencies in the US (1700 AWS for TMO). An ATT N1 can't use TMO's 3G and vice versa.

thanks, and i can do this without having a custom recovery? just use adb? and do i literally just type "fastboot flash radio radio.img" after going into cmd? sorry for all the questions, I just wanna make sure i don't mess anything up

the N1 was unlocked but was used for ATT, is there something I need to do to change it to TMO frequency if that's the case?

It is hardware. Unfortunately it's impossible.

Right, it's hardware, not firmware. You need a TMO-specific N1.

great...so will upgrading the radio do anything for me? and if so, do i extract the radio.img to the sdcard or to sdk tools folder?

Oops, sorry - forgot ATT and T-Mobile run different frequencies, you won't be able to do anything about it.

no
it's hardware. you can only get 3g FROM tmo on a tmo frequency phone, and only get 3g FROM ATT on a att frequency phone. ... see ?
if you're using att, they're going to slam you with a $30/month fee for smartphones too ;-)

You should be able to trade the phone - the at&t 3G version is no longer on sale, so it is much harder to get than the TMUS version ... you should easily be able to sell it/trade it for a TMUS version.

Wildfire Radio Change

hi all,
already searched but could not find a definitive answer.
basically, i have a htc wildfire a3335 (850mhz version) and accidentally flashed to an a3333 froyo (2.2.1) rom, losing the 850mhz (my carriers primary network).
obviously i need to change the radio, but have had no success so need some help.
either
1)revert radio to telstra
2)downgrade and reflash with stock 2.1 telstra rom
3)somehow force the new OTA froyo update
i currently have a generic htc rom, but i don't use the phone much, so the stock locked rom will work fine for my purposes (don't need to root or anything, just make calls).
if anyone can help and is in the local area (melbourne, australia) i will pay well for their time.
thansk in advance,
josh

If you don't have a custom recovery installed your gonna have to wait for alpharev, or search for the telstra froyo ruu on shipped-roms.com (which I don't think exists).
If you do have one like CWM or AmonRa, you can check this tread, I think that there's a link for the "flashable" telstra radio so you don't go back to a branded version...

thanks for that
i gave the noobs guide to downgrading another shot, seems to be downgrading now. its a tricky guide, not really for noobs, but my basic computer knowledge was enough to work it out. took about 45 minutes, mainly me being scared and paranoid
will post after the telstra ruu completes, then see if i can get the froyo OTA update (which i should have just been patient for in the first place )

phew! all done.
thanks very much for the downgrade guide, was a bit scary and needed a lot of concentration, but worked without a hitch.
long story short, if you want your telstra phone updated, be patient!

I have a Telstra phone that I upgraded to a stock WWE 1.37 ROM.
It works fine on the Telstra 3G network at high speed.
The frequency it operates on is dictated by the hardware, not the firmware.
However if you swap provider to say Optus, then it will switch to 2G operation as the Telstra phone hardware works at 850 Mhz (and others) while Optus netwrok runs at 900Mhz for 3G operation. Therefore the phone will drop back to the 2G frequencies and network and therefore run slower.
Go to shipped roms and select an HTC WWE rom (but not Froyo) and you will run at full speed. Likewise the custom ROMS will be fine also.

Glad to hear that you could fix it.
By the way, a lot of us had to learn android the hard way!
So welcome to the forums!

i dont think this is correct, 900mhz is optus's copy of telstra's country nextG network, called 'yesG' and is only for rural/remote areas
in most places optus etc run 3g on 2100mhz
i have a testra wildfire unlocked running virgin (optus network) 3g/hdspa fine, and i use a virgin dongle with an parabolic external antenna that only works on 2100
since unlocking ive flashed CM7 and a diff radio to get gps working, but i havnt tested to see if i lost 850 support. i will want this back though (if gone) at some stage so will be looking into this more.

I don't think flashing the radio to 3.35.20.10 makes any difference to Telstra's 850 availability.
I am fairly sure that Carnarvon only has the 850 frequency, and I am still getting a 3G indication and 2.5 Mbps download speeds (which is about normal), so I think we are safe!
Cheers
John in Sunny Carnarvon - Western Australia

Flashing a newer version of the radio won't make you lose 850MHz support.
I'm running 13.55.55.24H_3.35.20.10 and when i moved back to NZ i first tried to use 2degrees as my network provider, but they run on mainly 900MHz and I couldnt get reliable reception at home, but once i switched to Telecoms XT network which is a perfect frequency match for the A3335 Wildfire (the 850/1900 from Telstra) I've had no problems with reception.
If you really want I can upload the original firmware from the Telstra rom as a flashable zip.

no problems, i will wait till i can test if it still works on 850 and was also wondering if flashing the radio that came with telstra could help get bluetooth working with CM7, but is prob more an issue with CM7

I think I have this problem too after I tried (unsuccessfully) to root my phone. Now I can only get some networks (Tmobile & Orange) but not my network (Talkmobile, which piggybacks Vodafone). I've been googling around about this for a while and I think it may be that I need to cahange my baseband. Current ver is EPU93_U_00.60.03. But I don't know how to do this. Any help to a noobe would be much appreciated...

You could try with Baseband Switcher 4, and select your baseband...Then you have to set the APN.

Hi,
I am from India.
I got a phone from my friend which is Motorola Droid RAZR M with is tied up with Verizon.
Now I want to use Airtel Service in India. After I insert the SIM, the phone recognizes the Airtel Service for a second and then it shows nothing. I think I have to unlock the mobile.
As I am completely new to android, could any body suggest how to do or how to make the mobile work in India using Airtel GSM sim?
Please provide the steps and the requirements as well.
Thanks in advance...

By doing a root using the link http://forum.xda-developers.com/showthread.php?p=32889627 will it help??? or by using bootloader unlock will it help? Please guide me or make me start to do something....

If you are using GSM no you don't need to unlock it.
Just make sure you are on Ice Cream Sandwich or Jelly Bean.
Stick the GSM Sim in there press okay if it says SIM form unknown source and you should get all ur signals.
If you are planning to use it with a CDMA Carrier then u have to do settings flash and hope they stick so u can ask ur provider to connect it to their network.
Also are you using Retail XT907 or Developer XT907 ???

any luck
so we're you able to make the SIM card work?

Thanks for the information but it does not seem to be working. I inserted a GSM (BSNL) sim card into it. Reset all data. When the phone restarted it says "SIM from unknown source". I press OK. It shows a few bars (does not show any data access). However I am unable to make any calls nor does it receive any calls. I even changed the "Preferred network mode" to "GSM/UMTS". Am I missing something? I could sure use some help here.

I tried flashing the aussie NON-HLOS.bin and it did not work. The operator was BSNL. Upon inserting the sim, I get an error saying "BSNL Mobile - An error occured". List of available networks was also empty. Only option is to rinstall some custom rom, I guess.

I have uploaded the file at h t t p : / / d-hDOTst/FpQ. (I am apparently not allowed to post external links until I have 10 posts.) Though I am not sure why you would want to do that.
Can some upload a copy of the original XT-907 radio? I am unable to find it anywhere. Thanks.

http://sbf.droid-developers.org
All of the currently available Motorola firmware files are available at that link.
Just download the full XML.zip for XT907 and use what you need from it or flash the entire file in RSD Lite.

New RAZR M
Hi,
Were you able to resolve it?
I have a RAZR xt910 and i am using the verizon leak and for me as well Airtel gets connected and everything with mobile network in status showing as disconnected. Just wanted to share that. Apart from that, i have something new i want to ask about.
I am thinking of buying a RAZR M for my friend, and its available here in India, Mumbai.
But the Reliance guy says its not a boxed piece and he says all imports are opened box pieces and that he has to open the box to edit some PRL settings to enable the phone or data or something like that. He is a CDMA phone service vendor.
Probably for you to enable the phone, you still might have to enable the PRL or whatever.
Anyone here knows what exactly he is trying to do? or is he bull****ting me for selling me an unboxed (probably used) phone from US. The price seems legit as compared to an imported version. And i am getting one year Seller's warranty, i.e. his shop - Reliance Webworld Communications(A known enterprise).
I have also asked this query in another thread for JBX custom Rom as i use that on my RAZR. Will share any details here if i find anything.
PS- I am going to his shop to understand what exactly he is doing so lets hope i find an answer to your problems as well.
Also if anyone knows how to get a proper box piece from US then that is also welcome. We will fix the not able to use issue here itself

This kinda happened to me (but in my case mine was just saying no service [ie the shield with a cross]) , are you sure your sim is activated (since it shows mobile network status as disconnected) or your carrier could just be evil and want you to sign up for a plan, in my case I told them I had a 4g device and to use my phone I had to sign up for a 4g plan (which I did on my lesser mb520) even though I had service (for about 15 minutes) when I just bought the sim and activated it at the dealer

Droid RAZR basically a World phone, means it can work on cdma/gsm networks.
when it got released it's GSM radio was disabled & in later motorola/verizon updates unlocked the GSM signals to make it
world phone.
FYI,
just google "droid razr world phone", you will see multiple sites reporting verizon unlocking the GSM signals on the phone to allow global roaming on GSM networks.

Dude !! i am talking about the Droid Razr M and not the Original XT912
tell me something i am not aware of
the newer variants of razr M arent letting the users to use them on gsm radio
if anyone can help then plz do

Guys plz help me out here
some how this particular razr m is not latching onto gsm network at all

Alcatel One Touch POP D5 BASEBAND

Hello guys, is my first time here
I need help with ... baseband change is possible? because i'm living in Argentina, and this cellphone have 3G: 900/2000
and here use in 850 and 1900 .. mtk not only allows other options mark 2000 and 900
thank you

sorry for being too late...
first of all. you seem like you want to change your baseband firmware???
right?
it's possible but not counseling you to flash your radio (baseband firmware) unless your phone is having network issues (3G network strength, connecting to towers, wifi problems ...)
but if it's only choice you have.. you have to find the right radio firmware for your phone..
because that process break many phones
