[Q] UK Unbranded Tab, Lost 3G and Modem.bin backup - Galaxy Tab General

Well, How do I start this..
Bought a Unlocked/Unbranded Tab during my UK visit. On the box states that it supports HSDPA 900/1900/2100 and QUAD-BAND. Perfect since I'm on ATT network, been using it for some time with no issues at all. 3G/H/Edge working great! Then I decided to do an PDA update and now I only have edge, I resorted back to what I believe I had before (JJ7) however I can olny get edge to work. I did check *#2263# and made sure that 1900 and other bands were on but still no luck. Is there any UK tab users that HAVEN'T updated their roms that could post what PDA/MODEM/CSC they are using so I may get may tab working again? Lost my backup during the update . So upset with myself for not backing it up to my pc first. UGH!!!!

I have a dump of the ROM mine shipped with, not sure what version. I think it was the latest official ROM in the UK.
Anyhoo, attached it the modem.bin I use. I should hopefully get you back with 3G

Many times the loss of 3g is due to APN settings being incorrect. Always look at the wireless network settings first.

Got it Thank you both. Now back to Phone=JJ6 and I have 3G again! Thank you GrammarFreak! I love my Tab once again!

[Q] Italian Sim on a T-Mobile Tab No 3G

I have flashed my T-Mobile tab and asked T-Mobile for a Sim unlock code and now it works fine with any Sim. I can place calls with the dialer.
My problem is that in Italy, the tab connects to the internet only in Edge, it does not use the UMTS network.
By going to the mobile settings I do not have the "use only 2G" option.
I have GSM/WCDMA automatic on the settings. By typing the 4636 code on the dialer, it seems already well configured.
any solution?
thx
What is your provider? Because if it does not use the 2100mhz frequency for 3g (t-mobile) you will just not be able to ever connect on 3g, it's not a problem of configuration but a radio incompatibility.
In italy 3g is on 2100 and 900mhz. If i read it right T-Mobile uses 1700 and 2100mhz so it shouldn't be a big issue.
However unless you are using a TIM sim, forget about EDGE: GPRS only for all the other mobile operators!
Maybe there is poor 3g cover where you are at the moment? Wind is particularly low on the cover side.
My italian operator is wind.
the sim I am trying to use is wind.
I am located in Milan.
I also have an N1 bought in the US, when google released the TMobile version (with the 900/2100 band) and in Milan gets the 3G signal pretty well. As soon as I put the Sim in the Galaxy tab, the data connection goes in Edge even when I have full signal.
thank you
What is your apn setting -"profili" from your screen shot? You might have to write down the values when your sim card is in your other phone, then manually add them to your tab.
That is the setting access point names.
There is where I have set up the Apn for my Italian operator. Since I have my nexus one with the 3G connection working fine, I am using the very same settings. The Firmware version I am using is XXJK1.

I already tried this. By checking the dialer code 4636 i have a pretty similar setting as the nexus but still it does not connect using 3G. I am not very techie but I wonder if it could be something related with the modem file I used during the flashing procedure. The calls work fine though.

Try the Roto 3g modem.bin file. Flash in Odin in the Phone spot, leave all other settings alone.
Was this solved? I'm in the U.S. thinking about buying a tab, in Sweden we use 2100Mhz for 3G. Will it work and which one should I get, T-mobile or AT&T?

sorry for not replying before. in the various posts I found two files, i wonder which one is the correct one to use with the firmware I have on my tab (XXJK1).
I would like to be able to make calls and connect in 3g with my italian sim
Which file I use?:
PDA_JL5modem.tar (modem.bin)
or the :
JMA_ROTO-2G_modem.bin
thank you
Actually, I would use the bell i9000 modem from the Roto JME post when using a network compatible to at&t. That gets voice and 3g. I would use the Roto 3g modem for a network compatible to t-mobile to get 3g, but not voice.

I downloaded a modem.bin file from one of the posts after reading one of the Roto posts but unfortunately did not change anything at all.
Would you please link me the post where I can download this specific bell i9000 modem, that is also compatible with a at&t? I want to use the tab for phone calls and 3G, as in Italy we have no voice restrictions as in the US.
Thanks

Galaxy Tab from Orange France HELP! (CANADA)

I just bought a galaxy tab that comes from france (euro version) AND I'm having trouble getting the phone to work. But i noticed a few weird things :
-the firmware is original but rooted . Its 1000XXJK5 and Froyo BVJJ2.
-i have the phone application but i get a message that i cannot use my sim card to make calls
-sms work . I can send and receive.
-data works with no problem. Even weirder,i get 3g speeds running on Rogers even though i thought europe 3g band was different. I even used the code *#2263# and changed the data mode for 850 only. I still get data connection.
Am.i missing something? or could it blocked by rogers?
any help would be appreciated
thanks

[Q] Defy, AT&T EDGE only

I have an unlocked Defy from T-Mobile USA that I'm using with my AT&T service, but I'm only getting EDGE wherever I go, no UMTS at all, and I've even heard of people getting it to run on HSPA bands. I know already that HSPA is available everywhere from my home to my workplace, thanks to my Atrix 4G. I've rooted the Defy and it's running Cyanogenmod 7 latest. Any help would be greatly appreciated, as I can find nothing on this forum or on Google to remedy the issue.
You should try to change the freq via baseband switcher.And restart.
Maybe you got the "2g only" checked in networks settings..uncheck that.
Settings >Wireless & networks > Mobile networks
You can also put automatic(2G and 3G) mode in GSM/UMTS network preferences.
Thanks for the reply Viper. I just noticed the baseband is set to some central Europe nonsense. Should I change it to one of the T-Mobile USA band settings? There's nothing there for AT&T.
Edit: I changed the baseband to US T-Mobile 3.Something, whichever was latest. 2G only was not checked. I'm still getting 2G only. Could it be my APN settings? Could I copy the APNs from my Atrix?
I'm having a problem with my AT&T connection as well, but I've been using my phone unlocked on the network since March with no problem. I'm new to modding, but OCD about streamlining my electronics. My friend suggested rooting my device and flashing a new ROM. I decided on stock Nordic Froyo, and it makes me so happy not to see all the T-mobile crap in my apps tray.
BUT the collateral damage is not so hot. I have no 3g or even 2g connection anymore. I tried the fix in this thread http://forum.xda-developers.com/showthread.php?t=944258 and was able to get a signal with 4 bars instead of the previous state of emergency calls only, but no letters like E or 3g and no ability to use the internet/transfer data. I also installed the broadband switcher in this thread http://forum.xda-developers.com/showthread.php?t=1052745 and tried all of the T-mobile US bands. No luck. I did rest the APN to default. No change. I've been using wifi, but will have to go back to work soon. Not having access to the smart part of my smartphone will feel sort of like having an arm cut off.
I'm not sure what to do next. I could try flashing another ROM, but from what I've read in the forums, that's no guarantee.
If anyone has any suggestions to help a noob, I'd be forever grateful.
Thanks in advance!
Thanks for the link, halah. Do I apply this as an update.zip from recovery? Or install?
Never mind, it won't work for me, for whatever reason.

[Q] No network with overseas carrier (germany)

Dear All,
I've bought a RAZR M in the states a few weeks ago and was using it with net10 after unlocking the device for other carriers than VZW. I found the instructions on XDA (http://forum.xda-developers.com/showthread.php?t=2166542) and it worked like a charm.
Two days ago I went back home to Germany and in joyful anticipation i popped my german O2 sim into the phone. To my surprise the phone did not connect to the O2 network. Since I've read about Germanese experience with O2 in Germany (http://forum.xda-developers.com/showthread.php?t=2017987) I was positive it'll work. However, when I set the network mode to "GSM/UMTS" and try to select a network manually, the list of available networks is empty (see screenshot).
@Germanese: Am I missing something?
I continued fiddling with the parameters available in the hidden radio menu (dialing *#*#4636#*#*), tried all options on the "preferred network type" parameter and changed the radio band from "USA band" to "Cellular". Still no connection.
Then I've proceeded with unlocking the bootloader and installing CM 10.1 to check if I get a few more options. Surprisingly in CM 10.1 I wasn't even able to choose a network provider manually, the option simply doesn't exist. In the hidden radio menu (which can be accessed in the same way as in the stock system) on the other hand the list of radio bands looked slightly different: I was offered to choose between US band, Japan band and two other options (can't exactly remember what it was and already reverted back to stock), while for all of them the actual frequencies were displayed. It caught my attention right away that there wasn't an option for a 2100Mhz band (which is the frequency all German carriers use). Needless to say I didn't get it working on CM 10.1 either.
Anyone can point me in the right direction?! Maybe flashing the AU radio from xt905 firmware? Although Germanese pointed out it works just fine with stock ROM?
Any help is super appreciated!!!
All the best!
Henry
Dear Henry,
My Girl is actively using Razr M (Verizon Model) In Germany Munich.
The stock Rom works but has very Poor signal as you see yourself.
We got her working nicely with the Australian Radio.
The other way was to modify some codes with the RadioCom But not advisable if this is your first run.
So yes the best thing to do is to do the AU Radio Flash Mod.
Hope this helps...
Thanks for the fast reply! Do you have a link to the RadioComm Mods you're talking about? I've used RadioComm for the "00" NV tweak to get the phone working with net10 in the US - so I have a little experience
Wooohoooo!
AU radio is working! What a hike
Can't say anything about data for now as I don't have a data plan activated yet. However, signal strength is good and call quality is absolutely fine.
Cheers
Henry
data working, but only egde/gsm
Dear All,
Got myself a data plan with O2 two weeks ago and it works on EDGE/GSM. However, I can't use UMTS/CDMA network.
@Germanese: How did you configure your girlfriends phone to make 3G work?
The NV value @8322 is still 00 - the factory reset I performed after changing it didn't have any impact on this setting. I've tried to change the preferred network type in the *#*#4636#*#* menu without any success. The radio band selection holds only one option: GSM/UMTS band.
Any other ideas?
Thanks
Cheers
Henry

G900M 6.0.1 update lost 4g (lte) connectivity

Afternoon all,
So, I'm in the US and on AT&T and couldn't get the 6.0 OTA update. I'm wildly guessing because phone is So Am and not No Am, so AT&T wouldn't update in the north. Update went fine, no issues that I can find with the the phone except now mobile data will not connect to 4g in my area. I have 2 G900m's, one is on 6.0.1 and the other is still on 5.0 . 5.0 connects to 4g, 6.0.1 connects to 3g...sitting right next to each other.
So. I know there are slight radio freq differences with the 900m. Is it possible that the firmware version i chose did not activate the 4g band when I updated? Any idea how I can tell which 900M stock roms would re-activate the 4g bands?
Or am I better off going back to 5.0 and living with it?
hmmm.. Looking at the AT&T update page, perhaps I should have tried with an update with as close to the baseband version as possible...CPH3 is what AT&T has and I'm running CPC3 which is Trinidad, I'll give the Argentine version a go (since my phone was originally a moveistar splash screen.
Thanks.
Well, that didn't fix the issue. Even though I'm connecting through AT&T towers, the data is connecting on CDMA. This isn't something the provider can affect is it? At least it's H+ instead of H...not sure how much of a boost that is though.
Let this be a lesson to you youngens....purchase a dang phone for YOUR region. oy!
pfft. ... .42Mbs down boy does that STINK!
Ok...YES I AM AN ID10T!!!
Mobile networks was defaulted to cdma...changed the default to LTE...wouldn't ya know it....4g. Put a fork in me...I'm done.
