[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.)

T-mobile 4g Radio

OKAY so I decided to update this thread:
There are two versions of the One X. One with aws bands and one without. I have a device without AWS (I am about 80 % sure). There are reports of people getting 4g on AWS with the Rogers Version as of now, and more testers need to check it out as it could still be possible on ATT.
This flash here theoretically could enable the One X radio to lach onto AWS (The radios here are for the One S Ville.)
http://ville.giev.de/?page_id=42
I have flashed all three, and although I did not get 4g, I got faster ping and a near immediate connection onto T-mobile. To all the people saying this will "brick" the phone, it does not and you have nothing to worry. But as always make sure to do a backup. The radio hacks for the Skyrocket/Note were also based on flashing the Galaxy S2 radio directly on top. This should work the same.

I'm interested in this as well. What does is involved and the risk? I don't have warranty on my phone, so I'm a little bit leery in being first.

if your rooted ull should be fine just make a back up of ur current set up. this is just a clockwork flash, it may not even flash, but if it does then there's a high chance of 4g.
i've done radio hacks before for the droid 3/skyrocket/note all from a similar concept. ex. flashing the t-mobile galaxy s2 radio on the note, to enable 4g.
if anyone could provide me with a better solution for an unlock i am sure i can get this to work. seems that the htc unlocker server is down right now
it's the same thing as flashing different radios via clockwork posted in the One X android dev forum

I'll give it a try, hopefully it won't mess anything up. So I just flash the radio in recovery. If no good, I just flash the correct radio again?
There is a one click no HTC Dev bootloader unlock in the Dev forum.

I flashed:

0.16.31501S.17_2_10.23.31501S.10L
From your link. It flashed correctly. The phone on data and voice still works. I confirmed the version in Settings is not my original:

I'm still on Edge, but I'm in a crappy cell area, so still not certain if radio or my area. I might give the:
Radio from Stock T-Mobile US (update by rhcp)
0.16.31501S.02_10.18.31501S.08L
Radio a try too.

good to hear no negative results got my phone unlocked so i will be testing tonight. also do u guys have the newer sims or older ones?

I have an older sim I believe. It is one that came from an activation kit I bought off ebay. I tried the T-Mobile radio and same results, still on Edge, but still could be my location.

What in gods name are you guys doing! ? Are you trying to brick your phones? It's already been confirmed that the hardware on this phone does not support the proper bands for T-Mobile 3g!

It's not just the SOC that determines hardware compatibility. There are various radio amplifiers and filters which are tuned to the specific frequencies that the phone is likely to encounter. If a phone is going to be sold in multiple markets, sometimes the hardware filters are set up for all frequencies and some are disabled via software, but often times this is not the case.
It's not impossible that a radio reflash can make it work, though highly improbable.

Interested in this. There might be better luck flashing the tmo radio since I don't think any European operators use AWS bands, correct me if I'm wrong.
Can anyone explain why flashing this radio from a different device won't brick our phones?

I have a tmobile one s, but i also have the one from att and i am so interested on using this phone over tmobile 4g let me know if i can of help. I am using my micro sim that came with the one s and i am getting edge (asume its the latest from tmobbile 4g mucro sim. I am on 1.85 rooted but i did not unlock. though i am sure we can flash through CWM. any ways i am sure there is a way out to get 3g or 4g on the one x on tmobile did not find the way yet.

flashed both of the t-mobile modems no luck for me either, although my ping is significantly higher and connects to t-mobile a LOT quicker.
does anyone know how to edit the LTE settings. it is odd but for most ATT LTE phones they have the 1700mhz frequency i think it would be a matter of just defaulting that....
the radios also show up in my baseband so i have successful flashes
EDIT: one more thing, before i was not able to use data at all considering i had the newer t-mobile sims but now data works but on edge speed.

it's just a file in your system. it could potentially brick your phone but you can always get into recovery and restore. which is why i stated you should create a back up of your device before trying it out.
however, i was fairly certain it wouldn't do that because the internals of the One S/One X are nearly identical, they both share the same processor and most likely similar (if not same, radios).
either way, the the radios work, getting me higher ping, and working data without having to switch out my sim for an older one, hope there is a way to activate the 1700 band !
http://www.gsmarena.com/htc_one_x_at&t-4614.php
EDIT 2: apparently there are two models of the ATT One X/XL one with the 1700 band and one without

Likely the software has been changed to support T-Mobile, but the hardware (filters, amplifiers, etc) are non-existent, so you'll never get actual 1700 MHz AWS support.
Of course, this is just a 50,000 foot view perspective without actually trying it myself.

you might be right about this one but there are certain One X/XL's that do have the 1700 band found out through some searching and trying to figure out the reason behind it.
If that's correct.... the people with the 1700 band would have 4g when they flash this radio! also use *#*#4636#*#* to change network type to lte/gsm
--- for other phones though like the Skyrocket/Note they were directly compatible with T-mobile radios.

Okay, I flashed the Tmo One S radio and did not receive a brick. What I did receive is a not-so-good connection that will switch between HSPA+ and 3G quite often.
I don't have a WIND sim to test with, but I tried running AT commands on my phone and they don't seem to be working. I tried doing a network scan with AT+COPS=? waited forever and had nothing displayed.
Strange...

Rebooted and ran the commands again. Still don't see any AWS carriers.

Don't you need a wind sim to connect im pretty sure the Canadian version will work on aws

Confirmed on my end that even with the T-Mobile radio, I'm not getting HSPA+. Even when I drove by the Moscone center where 1900Mhz was refarmed during Apple's WWDC (maybe it was just that day?). I was hoping this would be like the Note and Rocket where I can flash different radios.
Any other new phone capable of this? The S III? If not, I may have to either wait for 1900MHz refarm or switch to Straight Talk.

I'm not exactly sure of this one.
If someone is willing to let me cut up their WIND sim (or lend me their WIND microsim), I'll re-flash the tmo radio and meet you somewhere to test it (Toronto, please).
~dan
-----edit-----
Just popped in an old WIND sim that I used to test AWS connectivity at first. Saw WIND Away with the standard radio, and after flashing the Tmo radio I see WIND Away and AT&T (AT+COPS=? shows Rogers, ATT, Telus, Bell).
I live by the lake, that would explain why ATT shows up.

[Q] Changing prl on the phne

I get very bad signal at my home. Even when i go outside in to the backyard of the home it is not any better. I know the prl has to do with what cell towers it will connect to. If i change the prl on my cell phone will virgin mobile cut my service? Reading a lot of places that maybe the only way to fix the signal problem. But virgin mobile does not allow roaming i am also reading. So what will happen if i change the prl on my cell phone to one from sprint and pick up more towers then i am suppose to?
Thanks,

Will something like this work for me to fix the signal problems i have - http://www.ebay.com/itm/Samsung-AIR...gnal-Booster-airwave-/360463338188#vi-content

To answer your questions......Changing the PRL will not cause virgin mobile to cut your service BUT if you return the phone to them with a PRL change they could void your warrenty.Changing the PRL could help with signal but it's not 100%.I have tried multiple PRL's and have gotten either no boost,little boost,or in one case worse signal.You may have to try ALOT of PRL's to get one that works best for you in your area.
To do the PRL change for the first time you need to be on the stock ROM to find out your phone's MSL.Doing this for the first time can take a long time if all the drivers for your phone haven't been loaded to your computer.Here's a list of stuff you need to do this.....Any cut app from google play,alogcat app from google play,and QPST 2.7 build 3.66 downloaded to your computer.
There should be a step by step guide on here for this.If you can't find it message me for help on this.Also please thank this post if it helps.

I also read Roaming does not work on Virgin Mobile! While roaming, you will not receive your phone calls or texts, and you can't make calls or send texts! Your data will also not work when roaming. If this true?

Changling PRLs will not allow you to use Verizon towers. Changing PRLs will only be of benefit if it provides an update of tower locations and allow you higher priority. VM users might get lower priority than Sprint users.
If you are using an old PRL, you may not have access to some recent tower installations.
VM users can only use Sprint networks. We do not have roaming privileges. Consequently, you cannot roam ... outside of Sprint networks. There are so-called hybrid PRLs, but i have never heard of anyone making one of those work. Other networks have their protocols in place and changing to a hybrid PRL is not likely to give you roaming privileges. It might provide you with the tower locations for Verizon, but that does not mean that you will be able to access them.
On the outside chance that you could, you would likely be breaking the law and certainly VM will cancel your account and/or bill you if caught.

Poor reception on S3 somewhat fixed

So let me start off by saying I have pretty bad reception at home with 4g.
I had an iphone 4 with a 3g range extender before I got the S3 and it worked great.
Found a free app called phone info
Went in under device information, selected cdma auto (PRL). I restarted my phone.
I now have 5 bars and perfect clarity.

I am usually about 2 bars where I am. Making this switch didn't change my number of bars or dbm. I'm glad it worked for you however.
I expect by making this change, you are basically downgrading to 3G until you set it back.

If you have a network extender for 3G then that's the fix. Not turning on thst option.

Not exactly. The phone will stay in 4g with one bar even if 5 bars of 3G is available. So forcing the phone to switch to 3G is the only way I got the call quality I needed to make calls in my house

Unstable 3G performance
So I've had my S3 for a little over a month and have noticed the poor call reception that people have mentioned,especially in my office building. My old droid 2 global never had a problem, but when I receive calls on the S3 i have to walk to A window down the hall to keep the call from dropping. In an attempt to stay on the more stable 3G coverage in the area I installed phone tools and forced 3G. The problem I have now is that when I'm out of the office or house and not on wifi, I pull the phone put of my pocket to check something and there is no data connection at all now. Even if I open my browser and try to force a connection I get nothing. If I set the radio back to include LTE I have a reliable data connection everywhere but my calls are still poor.
Am i missing something when setting the phone to be 3G only? Thanks.

Ok i tried that phone info program and set it tup cdma auto or whatever, and no improvement. How do i get back to stock? I tried setting to lte/cdma/evdo but it does not stick. I tried uninstalling the program and the phone would stick to 3g. Help!

I wish Verizon and Samsung would just get together and try and resolve why their phones don't work well on Verizon's network. I figured they'd learn what they did wrong with the Nexus - pretty upset they never resolved it with the S3. I'm hoping the DNA/DLX from HTC doesn't have this issue. I liked the Samsung S3 in just about every way but the reception is wretched compared to Motorola phones.

yea I agree...the reception is awful. Literally can't use the phone for business. Everything else about it is awesome though

It has to do more with your location I think..I work in the tri-county are of Detroit and my reception is excellent. Had a Cappy on ATT before my GS3 on Verizon and could not even get a signal in our office building..now on Verizon I'm at least 4 bars and full strength pretty much everywhere else..

It seems to have to do with the technology of the Verizon towers in your area. In LA with a motorola phone I lock on no problem and get great reception. With the S3 you'll switch from 4 bars - drop the call and switch back to 4 bars even when stationary. Motorolas don't have that issue with Verizon's network. I know several people with the S3 including people in CT and TX - all having the same issue on Verizon's network.

Just download the phone info app and switch it back to lte/CDMA/evdo when you switch it turn off the radio at the bottom and wait for a couple secs then turn it back on

I wish Verizon and Samsung would just get together and try and resolve why their phones don't work well on Verizon's network. I figured they'd learn what they did wrong with the Nexus - pretty upset they never resolved it with the S3. I'm hoping the DNA/DLX from HTC doesn't have this issue. I liked the Samsung S3 in just about every way but the reception is wretched compared to Motorola phones.

[Q] Can't receive calls while on LTE

I literally can't get any calls while connected to LTE. They all go to voicemail. I have been trying to figure this out for days. As soon as I turn off LTE I get calls on 3g with no problems. It also appears that when I'm on LTE if I make a call it had to drop to 3g before the call connects. Data works just fine. I have called sprint but they were less than helpful, updated prl and profile, and tried it in multiple different towns. Anyone have an idea of what to try next?

Whoops accidental thanks lol. If u check the other threads u will know that the way the new tri band phone's work, when on LTE all u get is data, on 3g u get voice and data, so while Ur connected to lte the only way to make or receive calls is for your phone to switch to 3g. This process should be automatic unless u manually changed something to force the phone one lte only.

That is so false because when I'm on LTE at my local mall, I can send and receive texts just fine.... the OP must've messed with some sort of setting is my guess..?

I have not messed with any settings. This has been happening from day 1. It took me about an hour after I got home from the Sprint store to notice that all calls were going directly to voicemail when I'm on 4G. As soon as I turn off 4G I get all my calls with no problem. I have tried updating prl and profile as I said before, but I don't appreciate people assuming I changed some setting when I'm telling you I didn't change anything. When I'm on 4G there is a spark icon that is constantly showing and the signal bar is always showing 1 bar. I don't know if that's part of the problem or not. If anyone has a serious suggestion to help instead of just assuming I caused this please let me know. Thanks.

Actually text over lte is possible but voice over lte doesnt work for us.
There is a giant s4gru article that explains it all

If I read correctly on the s4gru website then the reason ur having this issue is because the tower is missing the 3g upgrade that handles this handoff which is called Circuit Switched Fallback*or enhanced Circuit Switched Fallback. Here's a link to the s4gru page with this info if u wish to learn more about it.

False again. When at the mall I can make/receive calls as well. You CANNOT use data and be on a call at the same time though (like I could on my S4).

So what your saying is that everything that we know about tri band phones is false? The tri band phones only have 1 antenna so it is impossible to use voice when connected to lte period. When u make a call Sprint kicks you off lte in order to use voice and when the call ends Sprint reconnects you to lte.
eCSFB Gap Issue – What you Need to know:
Smart devices require eCSFB to “fall back” to 3G to accept a voice call if the user is connected to the LTE network.

Because I thought he said that you can't receive calls or make calls if you are on 4G LTE. Which you can, but once you dial out, or accept the call, you have no data.
Simple miscommunication!!

I never said you can't get a call while on 4G. I said I can't receive a call while my phone is on 4G. Something about my phone or area of service causes my phone not to switch to 3g for incoming calls so the phone never rings

i've been having the same problem! I live on the outskirts of the spark network so i only get the regular lte at home. and i dont believe the towers have been upgraded here yet because i wont recieve calls or texts unless i call out on my phone which forces lte off for 3g etc. but if i drive 15 min. north where the "spark" network is deployed then i'll recieve my calls and texts appropriately because the towers are upgraded there.
so sadly i keep my phone on wifi and cdma mode while at home then whenever i go out i have to switch it to lte/cdma and restart the phone so i can utilize lte while im in a "spark" area.
its tedious and sometimes i forget to switch back when i get home.. its such a pain. Leave it to sprint to deploy phones before their network is even ready for them.

Well the places without the 3g upgrades is not that big so they probably just decided to jump on to tri band even though development wasn't complete. It's like saying they should of waited not not sold any LTE devices until they finished deploying LTE, which means they would of still had old devices being sold.

well i understand that but at least when they first started selling the lte devices; the devices would still received calls and texts. because even though the lte may not have been upgraded/deployed or whatever yet. the cell phones themselves were compatible with the old network as is. but with these spark devices, they are deploying phones that may or may not work (the main point of a phone is being able to send/receive calls or texts etc) depending on where you are because half of the towers aren't upgraded for csfb
"Circuit Switched Fallback is a great solution to the issue of Sprint Triband LTE smartphones. But the problem here is that the Sprint network is being upgraded in Network Vision, and not all Sprint parts of the Sprint network can currently support CSFB. And it affects all Sprint Triband LTE phones, not just the Nexus 5 and LG G2." quote from http://s4gru.com/index.php?/blog%2...-technology/
and the problem here is the phone is supposed to be able to detect that the lte towers in my area dont have csfb and therefore switch back to cdma. But it doesnt, so it stays connected to lte and i never receive any calls or texts. but when i drive north to a spark network area the csfb works appropriately. So this leads me to believe its a network issue and not that my phone is a lemon.
idk maybe im just blowing hot air here but its frustrating that the most important part of my phone does not work properly for whatever reason in my hometown where i spend most of my time.

I know it's the reason I got rid of LG g2 but the only thing to do right now is put the phone in cdma only and keep checking if they upgrade towers yet

According to S4GRU what you are saying is wrong. In order for your phone to ring it kicks you off LTE. Circuit Switched Fallback. When you are connected to LTE your phone receives 0 CDMA signals (this includes voice). When sprint is trying to send voice to your phone, if the CDMA cannot be routed to your phone, the LTE network is checked for your phone, if found the LTE network drops you so the CDMA signal can get to your phone.
Give it a try. Make sure you are connected to LTE and data is in use. Have someone call your phone. Watch your LTE indicator change to grayed out, and switch to CDMA before your phone starts ringing.

No ISH, you still receive the call though, that's what I am trying to say..................

This whole thing is extremely depressing, just got this phone today and it's one of the first things I relized..sure I can put it on 3g and sit tight like that but come on the whole point in getting the newest flagship is how it's better than everything else, and sprint can't make it work right (yet). I noticed with my area that as long as the data is not actively loading a page or downloading it will switch to 3g and calls will come in but if it's load strait to voicemail..hope they get it all fixed the way it's supposed to be soon enough.
