[Q] JVQ HSDPA not working!? - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi guys! I'm having some problems with HSDPA after updating to JVQ. I'm on stock JVQ and I can't get to HSDPA... I only get 3G speeds and it's damn slow! I used to have HSDPA on JVP but after upgrading to JVQ it doesn't work anymore.
I tried the HSDPA menu but even if I change something the settings still appear on OFF and can't do anything about it. Can someone help me!?

Hi, I had the exact same problem earlier today with JVQ and my 3G doesn't work any longer.
The only was I couldmake HSDPA work was to download the APN configuration settings from my service provider, via their webiste on wireless, (THREE, Australia) and it works fine now
I suggest you attempt the same with your service provider. Good luck

[Q] Anybody with working 3G in Australia?

Hi, I'm a new Captivate owner - I'd like to ask whether anyone has 3G working on a Captivate in Australia and if so, what settings you are using to do so.
I can't for the life of me get 3G working at all. I'm with iinet who is an Optus network reseller so the network settings should be the same.
I've tried:
- Dialling *#2263# and *#*#4636#*#* to select the Australian bands (900 and 2100, sometimes 1800)
- Turning on data roaming
- Manually checking/adjusting APNs
- Pushing non-"850 by default" modems (JPP and JPY)
- Pushing the Optus (OPS) CSC
But nothing has gotten 3G to work on the stock eclair ROM (or Perception 10.1 in the case of froyo modems). Anyone able to shed some light on this problem?
Thanks in advance.
If not, then does anyone know of anything else I can try before I sell this phone? I'd really like to keep this phone if I could...
telstra......
hi , although i'm still waiting for my first captivate to arrive in the mail, i have a possible answer to that because i found the captivate in the reverse order, looking for a phone that would get 3g in oz and the us.... the captivate has access to umts 850/1900/2100mhz. (hardware?) so at&t uses umts 850/1900 telstra 850/2100.
so if you want full functionality telstra it is(unconfirmed)....... where in oz?
p.s. 3 uses telstra towers but you'd be roaming for data ...
i haven't tried as yet so let me know of your progress... also the armani modem would be the closest but again, it could be the hardware..

[Q] Lost GPS and 3G after installing Samsung ROM

[Q] Lost GPS and 3G after restoring Samsung ROM
Guys,
I can't find an answer to this, even though I did search a lot...
I upgraded my phone from 2.1 to 2.2 a few weeks back, and it broke my GPS and 3g, no data connection over the phone network, only WIFI. I enabled the option and added to correct APN settings, but still the 3G (And the associated icon) never worked again.
Few weeks back I installed Darkyys rom and both came back properly, after a few updates with Darkyys roms (7.6/7.8/8.0) and a few disapointments later, I decided to switch to the latest Samsung ROM 2.2.1 JPX, I lost GPS and 3G again, so I tried JPY today, again still no luck.
Any help would be greatly appreciated
Thanking you in advance
Maybe got an other 3G Band in your area than the firmware? The JPX/Y firmwares got a GPS issues I think. GPS don't worked for me too. Tried to flash Darky's v8.1?
Sent from my GT-I9000 using XDA App
Yes I think you are right, I am probably missing the Vodafone Ireland settings for the 3G.
No idea how do I go adding them, anyone?

[Q] "Your sim does not allow connection to this network" error

Bought a Galaxy S yesterday. It is originally purchased in the Netherlands, but i'm using it in Belgium now. When buying it, the device got tested with proximus and mobistar sim card (main providers in Belgium) and seemed to work (sms and calling worked). Getting home, putting in my mobile vikings sim card, I didn't seem to get any service. In my notifications bar it says BASE (which is the network mobile vikings uses if i'm not mistaking), but i'm not getting anything.
When searching the providers, mobile vikings is shown, but when selecting it I get :
Your sim does not allow connection to this network"​, which is strange since it's a mobile vikings sim card.
Never had any troubles, and sim card was working moments before testing on the galaxy S
No custom rom installed or what so ever.
Any help would be greatly appreciated since I can't do anything with the phone atm.
Thanks in advance!
I had this problem about 8 months ago... If i remember correctly I just had the wrong modem flashed... I was missing a modem with 850 band... try flashing Ugkc1 of jk4 modems... also check to see if your APN(access point names) are in your wireless settings

Click to expand...
Click to collapse
Just got a mail back from my provider, they're sending me a new simcard. But I doubt it's going to make a difference...
My apn settings are all ok. Don't know about my modem though...Don't know what it is, or whta it's supposed to be
I am pretty sure you probably need the 850 mhz modem in your area then..
what is your current baseband (settings>about phone)
New Sim card won't fix your problem.
My baseband is XXJG1, and I'm still on Android 2.1
My suggestion to you would be to download JS8 which is 2.2 and flash it with ODIN
http://www.samfirmware.com/WEBPROTECT-i9000.htm from here (you need to sign up)
see if that fixes your problem...
if it doesn't work, stay on JS8 and flash a modem(phone) file only that has 850 enabled... like JK4 or KC1 (there are more then those 2)
Just look up steps on how to flash with ODIN and check you tube for videos... just be careful...
Thanks a lot for the advice. I'll try it this weekend. (on a mac atm,and can't get heimdall to run)
UPDATE:
I tried flashing my modem without any result as far as I could see. Tried flashing darky, without result.
Got my new simcard from my provider, but nothing . I'm back on stock now FW 2.1 update 1 and baseband XXJM3.
Strange thing is that I get edge and 3G, to which I can connect. So my mobile internet from my provider is working, but no signal what so ever...
I'm starting to get desperate here...
I was also similar problem on my i9000t and i897 used in India. In my case the problem was intermittent. The solution i arrived at is as follows:
First select a modem that works correctly for your Band. Now force that particular band from SGS tools or going to service mode by dialing *#2263#. For example I force GSM900 for edge and wcdma2100 band for 3G. After that let your mobile choose select the network. Be patient for 10-15 minutes, it should work.

[Q] i9000T on Darky ROM 10.2.2 problem with 850 band

Hi!
I have been searching hi and low on how to recover my 850 band.
I bought in June of this year a SGS I9000T on my country, approved by the SUTEL which is a government bureaucratic branch that has the purpose of making sure the cellphones brought to the country can be used and blah blah. I currently live at Costa Rica. It was working perfectly fine up until the point in which I changed it CWM 7.0 and lost my 850 band. It was under 3G coverage.
During the installation my phone got bricked and I flashed several other firmwares where I had the i9000B and i9000M and i9000t, but in none of the aforementioned I got 3G coverage anymore (including i9000t).
I finally went to CWM and got tired of it. Eventually, I got back onto searching on this subject and found how to enter the service mode, got into *#*#4636#*#* to find I was on EDGE, then on *#2263# and activated my 850 band, with no result. It was active, but it wasn't ever actually used.
I changed my SIM Card three times making sure it had 3G coverage, I also changed carriers to find the same.
A friend of mine bought a i9000T and had perfect HSDPA coverage, paying the same as me, with the same data plan, under the same company.
I thought it was the ROM so I moved back to stock FW and had the same results. On each one of them I activated the 850 band and got the same result -- no 3G coverage.
Then I tried Amestris 3.3 and the same.
Then I went to Darky ROM 10.2.2 with the same result. I learned about flashing different modems, and have done so for the following:
TUBJV6
JVO
JPO
JPD
I am currently using TUBJV6, which is the same of my friend's.
My screen shows up the following under *#0011# command:
GSM: HOME(CS+PS)
Band: GSM1800, BSIC: 55
Reg PLMN MCC (712)-MNC(1), IsPCS
TchFrq: ,BcchFrq: 556
RSSI: -73, RxLev: 37
NOM: 2, TxLev: 255
TS: 0, VocType: 255
Cell_id: 10813, LAC: 5112
On *#2263# I have tried to leave it only to WCDMA 850 band but got no service message or emergency calls only.
All the Combi bands are active, including 850, of course.
I don't have a backup for the first ROM I used to have, but it was JPD and I tried it with no result.
Any suggestion? I am literally going mad over this problem.
Thanks in advance.
this probably doesn't help much, but I flashed darky's 10.2.2 today on a i9000t (venezuela, 850mz) coming from stock froyo 2.2.1 and I can still get 3G and H (which should be enhanced 3G, or 3.5G)
Also, I did not flash any modem other than the one that comes with darky's.
Baseband: JVQ
Also, make sure under your network settings you have your APN set correctly for your carrier! Although, if you can get EDGE, most likely you have them set correctly and your problem is not related to APN. But it's worth a shot. I know that by flashing other roms, the APN info is lost, most of the time.
Good luck.
bro,i facing the same problem with you!!!!
no 3G/HSDPA connection at all!!!! only connect with GPRS and EDGE
i just subscribe my data plan before flashing darky rom !!!!

[Q] Galaxy tab 7" not getting tomibile 3g

Hello,
I have a galaxy tab non branded with overcome installed.. I`m trying to get Tmobile 3g on the tab but no matter what modem i installed i`m always getting edge.. I tried with roto modem switch.. but still no 3g.. Tried to flash with tmobile stock modem but no 3g..
Model number GT-p1000M (SGHI987)
Firmware 2.3.6
Baseband T849UVjjB_ROTO-3G (after useing roto modem switcher)
Kernerll 2.6.35.7
Overcome-v4
I have tried the froyo, gingerbread now trying it to get 3g on overcome..
Please suggest me if i have to make any other changes to get 3g on tmobile network..
Thanks
bell mobility tab no 3g on tmobile
No one is having this issue ?
No 3g, just Edge signal
I too have a similar problem with no 3g signal. I'm in Bolivia and I have 3g coverage with my provider. I had upgraded to Gingerbread in hopes this would solve the problem. No 3g. I then installed the different modems and I still had the same (no 3g) problem. After this didn't work I went back to Froyo as a last ditch attempt since I had rooted Froyo in the beginning and thought maybe something got messed up. I've never seen a 3g signal here and don't know about the U.S since I've only use it here. Is it possible that the Galaxy Tab 7 3g just does not work in Bolivia? By the way, I've checked all settings and done everything to make sure things are correct. Any ideas? Thanks.
for @polapine, this is answered in another thread.
Basically the conclusion is that T-mobile uses different frequency for 3G/HSDPA, that a normal unbranded tab modem hardware is simply incapable of using. (1700 Mhz)
On the other hand, a T-Mobile branded tab can also operate at the "usual" 3G band in other networks in Europe/Asia/Australia (2100 MHz)
