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.)

Hi there,
I'm using Revolution HD 3.6.1 with its radio and relative RIL (which becomes with the rom by default). Obviously I have S-OFFed and rooted.
I'm experiencing some hiccups in 3G data connections. I don't know if it's due to the carrier (Wind Italia) or something in the phone (maybe the radio doesn't support it at all?). I'm in Europe, precisely in Italy.
Maybe should use an european version of radio? Or what?
In detail:
I activate data connection. The phone shows 3G before, and quickly goes in H (HDSPA). Then I use many apps that needs internet connection. Within a short time it goes again in 3G and i have absolutely NO data connections. After a delay of 5-10 sec it goes again in HDSPA and everything works. When it goes again in 3G i have no data, then again H and data working.
What's the problem?
EDIT: Problem solved! See in this post.
P.s.: Sorry for my bad english
I was going to ask about something similar to this, so rather than start a thread I will post it here. I too am running the 3.6.1 with its radio, S-OFF, & rooted.
What I am seeing on boot up is the standard progressive upgrades of data networks (just bars, then 2G, then 3G, finally H). The H only stays for a few seconds then drops to 3G and basically stays like that. However, as soon as I open an internet requiring application, it jumps to show H and typically stays that way as long as a data connection is active. My Speed Test results show its 4G speeds (same as stock ROM and radio) when its showing the H, so obviously its working, I'm just wondering if its intentional that the display only shows 3G? Or maybe its set so the ROM "relaxes" on 3G, but switches to 4G when data is actually being sent/received?
~T.J.
Maybe you used to have a 'background' app updating constantly.
The G, 3G and H usually depends on the signal in your area, the H is usually for high data transfer. If you're not using the internet,downloading anything or updating anything on your phone, then why would you need it on all the time?
3g is usually the norm, so I wouldn't worry!
For my issue, my stock ROM showed me what was available in the areas as I moved around, including showing 4G all the time if I was in a coverage area (which pretty much everywhere around me is). If I moved out of the 4G area for instance, it would drop to show me 3G.
This one just shows 3G all the time, even when I'm in areas I KNOW are 4G; UNTIL I use the data connection, then it switches and shows the H. I know its silly, but I liked actually gauging my providers service by being able to see what kinds of connections were available in various areas.
The fact I have to actually open the browser or run a speed test to see if 4G (H in this case) is available in that area is a little odd to me, why doesn't it just show the connection that's available?
~T.J.
Guys, I found a solution to my problem, googling around. That's awesome.
FYI I'll post here:
1. dial *#*#4636#*#*
2. Go to phone information
3. Toggle ciphering so it's off
4. Turn off radio
5. Turn on radio
6. Toggle ciphering back on
It seems to be working to me. An half hour without hiccups till now.
I have had this problem ever since my hd2 two years ago. I thought it was normal. I'm about to try the fix. If it fixes it you are a life saver.

Aww man same thing. Maybe its supposed to be like this.
Basically for me its for example on the xda app when ill refresh something it will always say processing as soon as the 3g symbol turns to h with both arrows on simutaneously.
Maybe that's how its supposed to be idk.

Only a brief temp fix? Are you sure?
I'm not having the same problem as before, now. I hope it remains still as it is.
I've completely lost 3G ability on my NS, and I'm not sure what happened.
Here's my order of tweaks:
CM7 nightly (with 3G)
MIUI (with 3G)
ICS rom from SDK (no more 3G!)
ICS from kwiboo (no 3G)
ICS from koush (no 3G)
CM7 stable (no 3G)
I guess sometime during my playtime with the ICS from SDK build, something messed something up and subsequently I cannot get 3G anymore, regardless of ROM.
I'm not sure where even to begin troubleshooting.
- Yes, "use only 2G networks" is unchecked
- My APN should be correct, as they are the ones that loaded automatically from the ROMs. That has always worked before
Anyone have any ideas? I'm desperate for help. I haven't had 3G for what feels like a month!
Here http://forum.xda-developers.com/showthread.php?p=19424857 in this post there is a link to the radios try flashing one of those to see if that fixes things. If not try flashing a stock unrooted rom and start over

You know what? A new radio worked! I don't know why I didn't think of it before. Seems so easy in hindsight.
This brings up another interesting thing. Seems like a lot of the radios that used to give me 3g don't give it to me anymore, including the most popular ones people are using. That's weird...
edit: Actually, no radio issues anymore. My old radio gets 3g again, as well as others. I just needed to rotate the radio versions a few times and reboot a few more times and it fixed itself. Totally weird, but no more problems!
I had the same issue on AT&T 2 nights ago. It turned out that it was an AT&T network issue which was confirmed by tech. support.
AT&T customer, midwest United States here. I live in a fringe area, but have always been able to get reception.... until I rooted and started running custom ROMS. It seems some ROMS, for whatever reason, get better radio reception than others.
I tried Viper, and while it was the best for reception, there were a lot of things that gave me trouble and I couldnt live with.
The CM ROMS wont even think about getting reception for me, unless the mobile data is turned on, and then are very erratic. I leave the data turned off when at home due to it always looking and searching and killing my battery. Well, that, and I always use wifi at home. I even tried the newer 3.18 AT&T radio, but it didnt help
Any suggestions as to a ROM that is known for reception? Or a specific AT&T Radio that is better for reception? While I knew different ROMS had different good/bad points... I didnt know the reception was on of those things.
Thanks

There sure is a big difference for some reason, with me anyway. The only 2 radios I have found in the Radio thread for AT&T without the RIL (senseless ROMS) is the 2.20 and 3.18 radios. I have bounced back and forth between them, and not seen any difference to speak of. The 3.18 seems to be the more erratic of the 2, for me anyway

My advice would be to try a different radio until you get one that works for you. I work out of state so I have to change settings to wcdma only to make them work in the area. I use the 3.18 radios on both CM and Sense because they work best in my home area. Viper is based on 3.17.661.2 so AT&T 2.20 may be the best option to try.
I use 2.41 seems 80% of the others I've tried plain suck in my area

When flashing radios for CM, also be sure that you are flashing the ones designated strictly for CM as the radio fw is kept in another partition than sense. I've never had an issue finding a radio that works for me. They don't all work well but at least 1 always does. When looking for the best radio, I download them all, test them one at a time, marking the signal strength and speedtest results for each and then flash back to the radio that gave me the best results.

Im getting the radios out of the radio thread here on XDA. I am d/l the radios in the lower section, for CM. I didnt try a different radio when using Viper, because it was useless seeing as I had so many other issues. I wasnt aware I could use Vodaphone or Telstra radios, on AT&T. I had only tried the 2 AT&T radios. My bad, I will try the others.thanks for the info guys. The speed tests are a moot point for me. As I said, i am in a fringe area. I cant judge anything based on data speed, and leave data turned off most of the time. Im not worried about data speed, or trying to fix anything in that area. Im trying to get my phone to get good enough reception to make/receive calls dependably and send/receive texts dependably. Sorry if there was some confusion over this.
Honestly, I would have stuck with Viper, but my wifi wouldnt work, and I couldnt even get my contacts and calendar imported from my Google account. In fact, there wasnt even a Sync option for contacts. So that was a no go.
Thanks again
The 2.41 he mentioned is not a ROM mate it's a radio.

Ok, I tried just about every radio in my CM ROM, to no avail. Then, on a whim, I ticked "2G Networks Only", and now I have decent phone signal/reception. This sucks though.... to have my data connection have such an affect on my voice signal. I had always left my data turned off when at home, due to being in a fringe area, and it always bouncing around and killing my battery. That, and I always use wifi at home. Now, I have to leave my data turned on, and in 2G mode... just to be able to make a call. Rather silly to me.
Thanks to everyone who offered to help... MUCH appreciated
P.S. when it was said and done, I think I wound up back on the stock radio for Cory's CM ROM (2.20?)

signal remains the same... around -87/13, but the Edge "E" icon, disappears from the screen. So, no real difference that I can tell.
It just amazes me that my data connection/type/settings can ruin my voice reception. Hopefully, its going to work decently now.

thank you! so far, so good! As long as I leave the phone in 2G only, my signal is great. Well, great for my area anyway lol.
With VoLTE being so far out yet, and AT&T not having true 4G, and voice/data being on 2 different frequencies.... how in the world is this happening on this phone? How can enabling/disabling data/4G/2G have such an affect on the voice/text signal? I just cant wrap my mind around this

I'm no expert by any means but if I were to take a guess, I would say it may be due to limitations of towers that are closer to you? IE: closer towers provide 2G signal but have not been updated to support 4G? and the towers that support 4G are further from you?
Like I said, I'm no expert, I'm merely taking an educated guess based on what I do know about the technology.

Actually, I dont know either, but that does make sense. If the phone is in 4G mode, then ti will try to connect to a 4G tower, which could be further away. But, there were times I had a great signal with 4G enabled, but it was in H, or H+.... and wouldnt make a call.
Im just happy I found how to get a decent... steady signal. I love the HOX, and I love the CM ROM... but I was ready to pull my hair out with this lol.
Thanks for the input, I may ask someone at the local store next time Im in. There is one kid in there, that is pretty knowledgeable. I think the rest of them know less than I do lol
Well, I spoke too soon. Now I have good reception, but the quality of my connection SUCKS! I have flashed and tried every radio for CM, and while I have a good signal now (around -85/13) my call quality is terrible and are all fuzzy and fade in and out.
I dunno, Im thinking seriously about going back to stock. I love the idea of having control over my own phone, but Im not in this as a hobby. I just want things to work right. Every ROM I have tried has had one issue or another.... wifi connection issues, wifi going to sleep when it shoudlnt, bluetooth connection problems, a dozen apps starting by themselves, radio/reception issues. Its to the point its just not worth it to me. I dont like having to work on anything every day, and if I do, I feel something needs to change in the situation, if that is the case. Dont get me wrong, Im not slamming any developers, or their projects.
When I was younger, I was always the first to get one of the Celeron CPU's and OC the snot out of it. As I got older, I thought... why? Ill just spend and extra $20 and buy the faster CPU so it is more stable, and not have to mess with anything. Thats sort of how I feel now
I was asked to also post this fix that I came up with in the general forum from the CleanROM thead, as it should help people having the same issue. The issue isn't actually related to that ROM but a broader M8 issue that I was unaware of and thought was specific to the ROM. It's been confirmed with multiple users having the issue that the fix below does indeed fix the random data issues that require a reboot/airplane mode toggle to resolve.
A fix for the 4G --> 3G, WiFi --> 4G, WiFi --> 3G, and 1X/3G --> 4G handoff issues that some people may be having is outlined below...
In a nutshell, we just need to change EVDO Rev A to "Enabled" instead of the 3rd "eHRPD" option in EPST.
Dial ##778 --> Edit Mode --> 000000 --> Modem Settings --> Rev A --> Enable --> Upper Right Corner Menu --> Commit Changes
Might cause a reset data connection with the transition due to a possible new IP or hamper simultaneous voice and data over 3G (which is possible), but it will allow the phone to establish a data connection on its own again and not get stuck on eHRPD 's random buggyness. Should transition back to 4G eventually as well
eHRPD basically for allows switching between LTE and EVDO systems seamlessly (no reset data connection from 4G --> 3G and back, slightly faster speeds, same IP, depends on tower...)
Changing this setting basically tells the modem in your phone to act more like a 3G phone when requesting 3G data access. Bypasses the hybrid-ness and just forces you on the legacy EVDO Rev A. network.
If the phone signal (4G is weak) at the time of the eHRPD transition, it can mess up. This change tells it to not bother with that and when the 4G signal isn't available just revert completely to 3G to register and not wait up for transition info. Makes it more cut and dry, and to be honest it does not really impact things. When the phone detects a 4G solid signal again it will switch back on all its own.
Same issue happened on the HTC Thunderbolt when Verizon was messing with things during initial 4G deployment. Only recent changes are the whole VoLTE ramp up, and that could be the cause of this recent crazyness.
To revert this change:
Dial ##778 --> Edit Mode --> 000000 --> Modem Settings --> Rev A --> eHRPD --> Upper Right Corner Menu --> Commit Changes
Thank you for sharing this! Very good find and positive feedback has been showing in response. Worth a try for everyone having these symptoms.

Isn't Android Revolution HD is in the Generic HTC One M8 section?
Sadly, this only works with VZW based ROMs. Anything with parts taken from other bases, or a GPE ROM it may not work and the code for EPST might be different/EPST might not work and/or the option may not be there.
That code doesn't do anything on the Viper rom

Sounds like you guys need to flash CleanROM...
After making a Nandroid back up of your current system then do the edit and restore Nandroid if you want :angel:
But to answer the OP, yes. GSM ROMS will not have this option unless the Dev adds it in. Otherwise its a CDMA only function (I believe).

It works on my viperone 1.8, are you on the newer versions that you do not have the new verizon firmware for yet ?
This is great, I come from an HTC One S but also switched between that and a Galaxy Nexus so I could tell a difference in the way my signal acted and we have had signal issues with the HTC One S for quite some time now and it all seemed to stem from when we finally obtained s-off, seemed our One S was never the same, may have been placebo but I was worried it was happening all over again with our blessed M8 lol. The One S was not Verizon and may not be the same issue. I just tried this and it already seems better.Thanks very much. They still have not found a fix for the HTC One S

I'm holding 2 M8's next to each other, one with the fix and one without, I am showing smooth 4g and she is showing a confused 3g lol.

The confused 3G one is with the fix or without?

If you go back to 1.8 then it will probably work for you, 1.8 was the last verizon that worked correctly for your verizon firmware. I was on the 2.3 but had too many wifi issues so I went back to 1.8, which is less wifi issues now with this fix I seem to not have any wifi issues so far so think its working for me. I"am not going to update viperone until the new verizon firmware is out in a zip to flash in recovery, because the wifi issues are not worth it to update now.
Any more successful difference's people have since doing this?
I was listening to a radio show streaming app today on Wi-Fi and the app kept stopping. every 10 minutes or so after trying this fix. It was the first time I listened to this app with this phone but listen to this app all the time with my other phones and never have this issue. It was consistently dropping Wi-Fi and 4g wasn't picking it up. I am running CleanRom with Harmon Kardon. I tried disabling Harmon Kardon to see if that may have been the issue since I am not accustomed to using it yet and it seemed to work better without it but still dropping signal. The signal icons seemed uneffected. I guess I am going to remove Harmon Kardon see if that makes a difference before I revert back from this fix.
I did this and my phone now reverts back to LTE and doesn't get stuck on 3G like it had been doing since day 1. I was getting tired of cycling into and out of airplane mode. Thanks for this advice/fix!
Is this the bug I experience where I have 4G signal, but am "offline"?
If so, that has been driving me nuts. I am on the stock ROM, S-OFF Rooted. Is this present with the off the shelf version?
Reporting back after 3 separate complete wipe/reflash/restores on my M8. Here is my status as of now:
Tuesday: Tried flashing stock recovery and did factory reset. (didn't fix the handoff issue)
Wednesday: Tried flashing RUU then returning back to CleanRom 1.4 (didn't fix the handoff issue)
Thursday: tried the EHRPD fix listed below. So far today NO handoff issues! I don't want to jump the gun, but this appears to have done the trick. I have gone from 1x to 3G to 4G with no issues so far.

If anyone is using the Verizon M8 with a GSM sim and can't access the USSD code ##778# then go into settings -> mobile data -> preferred network -> LTE/CDMA and try running the code again in the dialer. Dont forget to change the preferred network back to Global after applying the fix by the OP.
This has worked great for me. Thanks for posting. Was incredibly frustrating to have to fight with the phone every morning on my way to work to get it to connect to 4g. I had to toggle airplane mode, switch preferred networks and even reboot or some times do all of the above - lol. Thanks again.
Apparently this is a known issue and per Verizon, they're working with HTC to fix it. But I've also read that the problem could be cause by running xposed modules which seemed to be the case with me. I'm s-off running stock and was fine until I installed xposed.

This fix does not impact Wi-Fi directly, just eHRPD for mobile data transitions. Sounds like the app is the problem. Have the same ROM with Harmon Larson installed - no issues.

Yup. Seems to be impacting certain phones regardless of ROM. I'd give it a shot and see if it helps. If not just change it back.
Big thanks to the OP. I've been dealing with the the eHRPD limbo since I got my phone in April. I live in a low 4g area and was experiencing text and mms problems big time. It was always happening when it was bouncing for 3g and 4g. When I would check the network details it would say eHRPD. I would constantly toggle airplane mode off and on and change network preferences to get it to work. Really annoying. Well I tried this last night and the signal is staying in 4g almost all the time and I have experienced no problems with messaging. I am running Viper 1.8 and had to kind of guess to find the edit button after entering the numbers in the dialer, for some reason the Edit button did not show up but it was there when tapped on it. After that it was easy. Thanks again for the help. I wish Verizon was as good.
