[Q] Updated FW to JM5, now phone is trying to access WCDMA - Galaxy S I9000 General

First off I've tried searching for a similar topic and couldn't find anything.
So here's my issue. I updated my SGS which I bought from a local O2 store here. Checked that is was indeed unlocked and went ahead to follow the instructions that can be seen here in the forums.
After installation, the language was set to an Eastern European locale, which conveniently was easy to change back to English.
I could not connect to any network, so did all the app installations via WiFi. It wasn't until early this morning when going to work that I noticed that I didn't have any DATA going through.
Checking on the settings, I now have the option to connect to CDMA networks, instead of the option to disable 3G (Only connect to 2G networks).
What do I do to get that option back?
Thanks in advance for your assistance.

You need to manually install your phone network details or AP (Access Point) details.
Firstly check you have any details entered.
Settings > Wireles and network > Mobile networks > Access Point Names
If you don't have any details in here then you need to find the information and put them manually in.
Other then this you can check your Network Mode the next entry below Access Point Names and select the mode you wish.
Mine is GSM/WCDMA auto.
Wish you luck with it.

That's the thing, there are APN's on there and all. It's just that the setting for 3G had now changed to CDMA. Is there a way to just flash the specific CSC and not affect the PDA & PHONE?

PDA must always be flashed. THe other two you can add if required.
WCDMA is the same thing just make the selection you want. No need to flash a different CSC. I'm using JM1 at present and it's WCDMA as it's from Europe but it doesn't effect the phones capability. It's just a name.

Thanks for the reply. So what you're saying is, even if it is saying WCDMA, it WILL connect to HSDPA? Flashing my phone now back to JM5. All other FW's I've tried just show WCDMA instead of 3G.

Eventually settled for JFF and 2G option is back. Now I have the problem of the APN's working. Off to weed through these forums again.
Different question, same problem unresolved. So my original problem is that I seem to have lost all data connectivity (apart from WiFi) after the very first FLASH. OH well. Thanks for your assistance Ancient_One.

WCDMA is not CDMA. It might be confusing a bit, but it's actually two different things. WCDMA is basically just another name for 3G.
(Well, it's a bit more complicated than that, but for the sake of simplicity, let's just leave it at that.)

Yes, WCDMA is 3G. It's not CDMA as used by Verizon and Sprint in the US (they just share some of the radio-level technology).

Thanks for clarifying the bits regarding WCDMA. My how things have changed. Anyway, I'm going back to JM5 and am hoping to get internet up and running. It is so annoying to not have everything working as they should, even after the APN's been added and all.
Much appreciated guys.

[Q] Question about 3G network (WCDMA)

Hi all,
I'm struggling to get data connection over the 3G network, even though I've got a data plan and the settings seem to be on point.
I'm based in Dubai and I've got a Middle East tab (garbage as the firmware excludes the Android Market), so I've flashed a recent Euro firmware (JIP was the build if I recall)
When I go into network settings to choose 2G/3G/Auto, it shows me GSM and WCDMA as the choices. I'm pretty sure before the flash, it showed GSM and WCDMA. Is WCDMA the same as HSDPA?
The problem could be with the carrier, but I'm troubleshooting at the moment and this WCDMA is a bit confusing.
Any insights would be greatly appreciated. Thanks.
Have you checked your APN settings? Chances are that the Euro firmware doesn't have the APNs "pre-installed" for your carrier(s). The good news is that you can add them in manually if this is the case.
Regards,
Dave

If your display shows a 3G or H type signal, then your problem is a bad APN setting.
WCDMA is 3G and H on your display, if you have that then you're in good shape.
Search the net or the carriers website for the the correct setting, then create a new APN and data will instantly start to flow.
It was missing the apn setting. Justed typed it in manually and Im hooked up. Although i was bamboozled for a little while as the H didnt apear until i had turned off the wifi.
Thanks for all ur help guys.

[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] Signal Issues//Android//T-Mobile USA

Hey all yes I am a newbie, but I have been using roms for a quite a while I love the customization of the HD2, we are switching services in a couple weeks to either Verizon or US Cellular but this issue is bugging me like crazy, I used to be able to use my phone in the parking lot at my job, we arent allowed to leave on break, used to get 2-3 bars and an Edge signal, in a place Tmobile says I should have great coverage over the last couple days I have gotten no signal what so ever in the same place I used to use my phone every single day for about a year. I sit there for my whole break trying to talk to my wife while refreshing networks, auto selecting it or manually gives me 4 full bars and an edge signal then it all goes away. I guess why I am posting it to see if anyone has suggestions to what I can do to fix it. The phone works fine at home and on the road just not near work anymore. I have always used different roms, and never had the issue at all, always full task 29 wipes, my current build is
CyanogenMod Version PARANOIDDROID
Kernel 2.6.32-ics_tytung_HWA_r2.4_uniMAC [email protected] #272
Baseband 15.42.50.11U_2.15.50.14
Any suggestions are appreciated! Thank you again! Jake
I well ask a obvious question, have you checked your APN's. I knowyou are getting a data signal but maybe one of the APNsettings need to be changed.
Also do you have you checked in Settings/Mobile network/Network mode. See if you have WCDMA only, GSM only, or WCDMA/GSM auto.

Thanks for the response, my only APN is epc.tmobile.com and I cannot locate the network mode... No network mode setting that I can find.
Edit:: Found it its set to WCDMA Preferred is that what it should be?

Try WCDMA/GSM auto that way your device can switch back and forth as needed between WCDMA or GSM as it needs to.

[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

4636 menu ) SOS! NEED HELP!

Hello dear XDA Community,
I have an american Nexus 6P (used with Verizon) which is currently used with a Russian cell carrier "MegaFon"
I had troubles with connecting to their LTE, for some reason my phone just wouldn't connect to the LTE and only stick to HSPA or HSPA+ even though an iPhone near me gets LTE signal just fine, the SIM card is fine in the other phone as well. So I started messing with my phone to find if I could fix it, first I started with going back to full stock, that didn't help, the phone still only accepted HSPA signal. Then I tried multiple ROMs and Stock Images but the issue of not connecting to LTE persisted. Then I found out about *#*#4636#*#* menu (aka Phone Info menu) and I started messing with it, which again did not do any good until I hit the menu button and pressed Select Radio Band (P.S. please don't mess with those settings) where I tried selecting all 3 different "GSM/UMTS" Bands. I tried USA band, Band mode 6 and Band mode 7, but this just broke down my signal completely, I cannot connect back to the carrier network no matter what I did. I've tried factory resetting, flashing radio img's, flashing stock/custom. NOTHING HAD HELPED/WORKED
I'm now stuck with a phone that doesn't work at all, and I'm on business trip so I'm just pulling out my hair for messing with those settings in the first place.
Does anybody know a possible fix to this? How could I go back to what I had before even though I tried all kinds of forms of factory resetting the phone
I really beg for your guys' help
Thank You
EDIT: Found this http://forum.xda-developers.com/nexus-6p/help/recovering-usa-band-to-auto-mode-4636-t3271347 gonna try that right now
EDIT2: That modified ROM helped! But I still don't get 4G
Have you tried removing the SIM card, rebooting the phone, then going into the Phone info menu and setting the preferred network type to LTE/GSM auto (PRL)? Maybe afterr another reboot with the SIM inserted the phone will connect.
Also check the APN settings -- they might have changed.

I think I've tried it, I'll give it another try after seeing if flashing this one ROM where you can select Auto Band in 4636 menu that I linked in the edit would work.
APN settings were fine.
Thanks
EDIT: That ROM helped! But I still don't get 4G
Looks like the post you linked should do the trick. Good luck!
