[Q] HSUPA and Data on Captivate Help

I seem to be having an issue with my data and am trying to narrow down the reasons for my problem. The issue is I CANNOT use HSUPA (H) for data, I always get a connection timed out issue. I put the phone in 2G GSM mode only and have data working, but of course I was spoiled with better speed I can't stand it.
My question is if AT&T could be doing upgrades to the towers in my area, will that affect my speeds, or is something broken internally in my phone. When I select WCDMA mode, it takes FOREVER for it to connect and says searching for a long time but does connect or displays (H) with 3/4 bars of signal. My friend has an unrooted captivate on 3G and has no issue with data. Does anyone know the cause of this.
I have tried a few different modems (jl3, jk4, kp1....) all the same and have tried 2 different OS's with same data timed out issues while trying to use (H). I am currently in the process of flashing back to stock to see if that will resolve the issue. Thank you for your time guys.

H doesn't necessary mean HSUPA. It simply means HSPA (HSDPA only or HSDPA and HSUPA). You didn't mention anything about your firmware but I guess you are experiment with non-Captivate firmware and modem combination trying to get HDUPA working. From what you described, it seems your current firmware and modem combinations lacks 850MHz support for 3G (most European firmwares lacks 850Mhz) and your local tower happens to use 850MHz, not 1900Mhz. Just a guess.

Make sure you have the modern set to proper frequency (WCDMA 850 or 1900) for your area. The modem thread can tell you all about how to do it.

Sorry guys, I guess that was an important part I forgot. I was running Andromeda and thought the same so tried Cognition 4.1.1. Also after going to stock 2.1 I still have the data issue. I can connect to wifi just fine, but no using ATT data will work.
I called customer service and walked through the steps as usual and after some looking into my area, he said there were 3 towers reporting severely degraded. It just sucks seeing my friends phones working with no issues. He said that repairs are stated to be finished sometime in the next few days and to call back later in the week if the problem persists.

Looks like you tried both i897ROM and non-i897 ROM, so it's not firmware related.
Did you try to put someone else's SIM into ur captivate? How about some other devices in ur area?

I didn't think about trying my friends sim card. I will test tomorrow morning. Ty for the idea to isolate the problem to my phone!

umm not really related to your phone. but im suggesting its the tower upgrades getting them ready for 4G that is causing your phone to act up. i have a HD2 and we have 3G down here. but since early march i get nothing but EDGE. what happens in the month march? AT&T will be launching 4G in selected markets. it was confirmed once i was talking to a AT&T tech. so im just waiting to see what happens in the end of this month.
NOTE: it could also be your sim card having problems. AT&T replaced mine thinking it was a problem with the sim card since i have a AT&T native W350 and i was getting the same problems. call them up again and ask to talk to a tech and tell them your having a problem with your sim card. they will set you up a appointment at a corporate store. free of charge.

I did not think that the Captivate's hardware was capable of HSUPA?
Is it?

you would have data, but no voice

Sorry for nor replying sooner. My 3G data seems to be working again. My lack of in depth knowledge is why I put the hsupa above when my phone displayed H I didn't know what to call it.
It must have been tower upgrades. I didn't restart my phone and left it on the charger overnight and the next morning I had no issues. I did a reboot of the phone as a test and connected with data with no issue. Too bad as I was close to getting a replacement, though it would suck and be my luck to get one with other issues. Mine is a 1007 and works perfect (other than the obvious GPS.)

How to at least get 3G back for now while verison works stuff out.

If your someone whos stuck on 1x this will at least get you back to 3g.
Use the ##778# menu (hit call after ##778#)-->password is 000000-->modem settings-->Rev A-->choose enable-->hit the menu button on the tbolt and commit changes
Update:
So to answer the question of should you change this back?
The default setting is eHPRD which is verizons simultaneous voice and data 3G network. By hitting enable your switching your phone do EVDO or Rev A is pretty much their older 3G netowrk. The info is yours now you make the call of weather you should or shouldnt
To Revert back once everything is fixed:
Use the ##778# menu (hit call after ##778#)-->password is 000000-->modem settings-->Rev A-->choose eHPRD-->hit the menu button on the tbolt and commit changes

So is this a network problem or a phone problem because of flashing radios?

Actually I think it is just 4G. The reason our phones lose 3G as well is explained in this article.

The issue with not getting 3G can be fixed by following the instructions in the OP.

It worked on my phone, although it did take a minute or two once my phone rebooted before the 3G connection started. That was probably because I am in a building that actually gets great 4G coverage, but spotty 3G coverage.

If you want to do voice and data at the same time over 3G yes.

Thanks for this. I was beginning to think it was the rom I was using.

I wish i'd have seen this sooner...I thought it was the ROM as well and unrooted my phone this morning just to find that wasn't it. CS informed me there was a nationwide outage after the fact (I have been stuck on 1X since yesterday)
Quick question - I was so quick to try this that I didn't pay attention to the original settings of the phone does anyone know what they are so I can revert back when the system comes back up?

Hanks for the quick fix! Any negative affects of leaving the settings like this even after big red gets their **** straight? Oh, btw, I am in NC with no 4g coverage at all. This worked like a charm.

Is anyone having 4G issues?

Im in NYC area and have been stuck on 3G for two days now. Im not sure if has anything to do with the ROM I have installed or if it is network related.

4G working fine here in northern Jersey. On BAMF 3.0 RC2, MR "2.5" Radio.

Yes...4G spotty here in Los Angeles

Im in Northern NJ, running the same thing as you and I've been on 3G for days now. I even reflashed the radio this morning.

I can't get 4G at all in Houston right now. I only noticed it being unavailable today. (thought it was the mr2 radio I flashed but maybe not since others have problem too).

I've been having 4g issues since this morning. ZIP = 90024 (west LA)
3g works fine though.

i just took the sim card into the store. i told them i left my phone in my car because the battery is dead and it is charging. the guy kept insisting that i bring it in so he can make sure everything was working okay and i said, no its okay i know what i am doing and rather do it myself thank you. he swapped out the SIM.

Same here and now web videos are not loading either.

My battery has been dying so fast that I've switched over to 3G unless I need to download something quick or tether.
Same with my employee that's on my account, we're both constantly charging our phones if we leave it on 4G auto in the radio settings.

Funny though. I think, for some reason, the MR2 radio has to do with the 3G draining so quickly. I had the same issue while on 3G.

The stock radio dies in 3-5 hours on 4g, for me. Using CM7 with stock kernel I get incredible life with 3g, but 4g just eats it.

Lost LTE

I have ICS-SUPERLITE-4.2 on Rogers and i totally lost LTE. I wrote in many existing threads and dev section and no one answered.
I lost LTE, even in areas of full reception, i dont have it, i used stock APN and LTE APN and still dont get it. I do get 4G.
Other on rogers running 4.2 have lte, just less reception so im guessing radio is not the problem. Any idea?

mhx did say he broke lte in 4.1 so maybe you got something from that. im flashing now and ill see how it goies

well im on 4.2 so its supposed to be fixed

I was having lte issues on 4.2 aswell

LTE works fine. Just make sure it says ltemobile.apn instead of rogers-core. If it still doesnt work then go int the phones menu *#2263# and select option 4. After that go back into the menu again and select 1 for automatic.
Click to expand...

I've had to use the *#2263# option to get LTE on every ICS ROM I have tried so far, works great but sometimes I have had to redo it after the 2nd and 3rd reboot for it to take...
Another solution is after you flash an ICS ROM is to have patience , if you wait 5 minutes or so after flashing, before even touching\unlocking the screen, then most of the time everything settles in nicely on its own.

if ur using rogers with the ics leaks, there's several issues. Call id and lack of lte being one of them. This issue is present with all of them, it is an unstable leal after all. i believe lack of lte unless near a strong connection is due to uclca4 issues.

well after doing what i wrote 2 posts above, i have no issues with phone except for reboot/power off hang, i also get the occasional 2-3 second lag but its quite rare. Besides, im very haapy with rom, battery life is much better than GB

no lte after ics leak
I've the same issue with AT&T in Miami which has a strong LTE network. LTE worked great with GB. After installing the ICS leak all I get is HSPA:11. When I go into *#2263# it says RAT Selection option is restricted. Anyone have a solution?

Probably don't have the correct apn. apn needs to be set to pta in order to get lte.

Ditto - well actually I AM seeing LTE, but a drastically reduced data rates. Does not seem to matter what ROM, or Kernel or how many times I have re-flashed or re-flashed just the ICS Radio, I get roughly HALF of what I was seeing on GB. Ugh. I don't WANNA go back to Gingerbread. I just want perfection. Is that too much to ask for?

It's not the APN, at least in my case. It just crappy reception, and it happened exactly when I flashed ICS, and has been like that ever since. This in spite of re-flashing the Olin leak, reflashing the the radio, etc. It really irks me, and I do NOT want to go back to GB

Does your data icon still appear or does it come and go when that happens?
My phone does that at my house because I have 3 towers with great signal and the dumb phone jumps back and forth all day so fast/much the 3G doesn't get to stay caught up so it drops and comes a lot.
Once all LTE shouldn't be an issue but I imagine your phone is either doing similar or jumping between LTE and 3G a lot maybe due to one being weak?
Try CDMA only mode for giggles too. (under more networks on settings).

I don't know what the problem was. I just uninstalled the Playstore update and ran it, which went through and connected alright. So far it's been working after that.

Today I'm getting the same "connection timed out" error again on Playstore. I don't know if it's just me or Playstore has issues?!

Is Playstore only spot you have issues?
If the connection is really slow this will happen too.
To eliminate it being Playstore just try WiFi.
I'd bet it's the data connection though. The question would just be the cause and why. Is it dropping or just slow and if dropping is just the area tower etc.

Yes, Playstore is the only one having connection issues. I did the same trick and got it back.
But, you're right, I think the connection at my work area is not the greatest. All the carriers get 4G/LTE in my cubicle, except for mine. I have yet to see anything other than 3G, but not losing hope.
