VZW xv6800
Loader: 2.40
Radio: 3.39.10
ROM: DCD 3.1.2
I see lots of discussion concerning GPS and Bluetooth (BTW the 3.39.10 GPS aq. speed is awesome) but not so much about Data Connection. Maybe I’m just not looking in the right place or using the right search terms.
Not sure if I’m putting this in the right forum, but this seems to be upgrade related, and quite honestly, the caliber of posts here seems a bit higher than in the general Titan forum.
Since upgrade my Data Conn speed is a whopping 150Kb/sec. Ugh. I have tried it tethered, Bluetooth, PDANet, PAN, indoors and out. Even tested IE Mobile to http://text.dslreports.com/mspeed . Never got much above 150Kb/sec. I typically got ~600Kb/sec before I upgraded my radio.
Maybe I’m having a bad air week and pushing a low DRC, I’ll continue to test, but my question is this;
For the purposes of troubleshooting/testing, how can I tell if I’m getting an EVDO Rev A connection (I know it is available here)? Is there a way to turn off Rev A and force a 1X connection or vice-versa?
Anyone else having problems with Data Conn. Speed? I use this fairly frequently and while I am just euphoric over the GPS, I may run into a serious dilemma when professional stress demands a faster connection.
You have rev A. As for the data speeds hmm- is you phone possibly set to 1X only? To check go the the phone settings menu and under the 2nd tab it says Mode of Operation, click that
Was set to hybrid.
I tried with EVDO only. 177Kb/sec
1X gave 121Kb/sec.
Have set it back to Hybrid, icon shows 'Ev', but still not sure if it is Rev A.
Signal is strong, would hate to have to roll back to stock just to test if the problem is with the Radio. What speeds are others getting with Radio 3.39.10?
Edit- What I am thinking is that I am getting a Rev A signal and maybe it is more sensitive to SNR and dropping my rate. Thus I want to turn off Rev A to test. Then again, maybe I just don't know what I am talking about.
check your EPST settings. if RevA is ENABLED, change it to DISABLED. its a misnomer.
No such entry in EPST.
Also,

Been there, done that.
Thanks for trying.
Tried both with same speeds
Just tried both settings and the speed tests had the same results.
I'm using Radio 3.39.10 and Rom3.39.10(Sprint), have the option to enable/disable Rev-A but my speed is still 419.40 kbps. no matter which settings I choose.
what location are you in?
are u sure its one of the locations that has reva?
what radio did you have before you updated to 3.39? did you let customizations run?
I upgraded for the first time about a week ago. I initially went to Radio 3.37 and ROM DCD 3.1.2 and the VZW CAB using the SD card method. Customizations ran after the DCD ROM flash. Everything works seemingly well, other than the slow Data Connection. Yesterday I flashed to the 3.39 Radio. GPS Acquisition went from 60+ sec to < 10 sec. No change on the Data Conn.
With Stock Radio I typically received at 600Kb. Now it is 150-170Kb.
I’m in the SFO bay area, but beginning to think that Rev A is a red herring. Don’t really know much about how Rev A works, but after reading a great deal about it, connecting to a Rev A equipped station should with or without a Rev A equipped mobile should not affect the connection speed adversely. One either has a strong and clear enough signal for the higher speeds or one does not. I am connecting via EVDO, just getting really slow speed for no apparent reason.
Tigueraje reports speeds of 419.40kbps with Ev or 1x. Wish I could get even that. BTW, 1x should not go that high, so was probably connecting to Ev both times. If you truly want to check your 1x speed, try a soft reset, or at least stop and start the data conn after changing.

Thanks, I'll look into that. Hope this is safe to do on a VZW phone. My PRI Version is 1.35_002 and my GPS is rockin', but I will proceed carefully.

i cant say that its safe on vzw. that post on ppcgeeks was a telus user...
sorry if i was misleading in my last post, i thought the OP was telus.
I haven’t done anything yet. After a rush to upgrade the Titan when I first got it, and many problems afterward, I have been proceeding very cautiously. I’m not confident that the PRI update will address my issue.
I just talked to a co-worker on VZW with a Treo 700wx. He is also having problems with Data Conn speed in my area. So, I think this is just coincidental to my upgrade. I will keep tabs on it, and if I can get down to Campbell this week (a verified strong Rev A area) I will test there.
Still curious about what speeds others are seeing with the 3.39 Radio. Anyone confirm Rev A (anything over 1024Kb/sec)? On VZW?
Alltel user here, just flashed to Radio 3.39 and have gotten two different download speeds of 1045.
Thanks for the info.
Just tested in San Jose, Ca (about 15 miles from Home) and got 927Kbps. Problem must be with the tower near home and coincidental to my upgrade.
927 0.204s (1024k) myvzw.com Mozilla/4.0 (compatible; MSIE 6.0; Windows CE; IEMobile 7.11) 320x320; VZW; UTStar-XV6800; Window Mobile 6.1 Professional;
To clarify REV-0 VS REV-A
The download speeds you see when looking at EVDO will not be majorly different, it is the upload speeds that REV-A is most meant to address. REV-0 theoritical download speed is 2.4 mbps, and upload is 153.6kbps and this is shared bandwidth. REV-A is 3.5 down and 1.8mbps up. A DOM module will take from 1 to 4 T1s in and at the moment most VZW sites are running only 1 and some are running 2, so with a max BW of 1.54 mbps on a T1, you will not ever see the max download speeds of REV-A until 3 T1s or more are at the site, and like I said it is the upload that will be most different.

This has started to happen recently. I am with AT&T Wireless in Brooklyn, NY. The phone used to carry the signal around almost the whole day and never lose it, but these days if I leave it alone for a while and come back it may say "no service" or "searching..." . If I do a soft reset it may find the signal, or if I turn wireless off and then on (which doesn't always respond, by the way -- on my phone it's called "Turn on Flight Mode". Is that what it's supposed to be called?)
I got this phone two months ago and I am extremely thrilled with it. It's a phone, pocket pc and (video!) camera in one. Sometimes it can achieve great clarity on conversations.
I wish someone can help me out though with some advice or information on upgrading the phone. I have the following questions:
1) What GSM frequencies does this phone use? Can I make it work with AT&T's 850 band? Is anyone familiar with making this phone work better with AT&T wireless?
2) What are some of the icons I see on the top, such as the G in a square? On my old phone that used to mean GPRS connection (i.e. internet/wap). I don't know how to control these things. To turn wireless off, I click a link that says "Turn on flight mode."
3) Finally, what can I do to stop losing the signal?? I tried putting manual selection of the AT&T Wireless network on, and it didn't improve things -- the phone still lost the connection. Once it had the connection thoguh, it didn't drop it -- I don't know why the connection gets lost.
Thanks a bunch for any advice and info,
Greg
Egreg,
I have similar problems. My provider uses GSM 1900 & 850.
1) It uses GSM 900/1800/1900. Unfortunately doesn't have an 850 radio; which is really bad, they should have made it a Quad Band for the price we pay for it. GSM 1900 is really terrible in buildings etc.
2) G Means the radio has negotiated GPRS availability.
3) I've gotten better results with signal locking on by following this thread:
http://forum.xda-developers.com/viewtopic.php?t=7619&highlight=signal
Download the application and set it to "Search GPRS on start GPRS connection". That way it doesn't have to negotiate for GPRS unless you actually want to use it (helps to establish signal lock much better as there is less protocol overhead).
Also now, I'm using Radio Version 1.06 & 1.08 as they seem to reconnect much better than 1.14.
Hope this helps.. Mine is performing much better now, not perfect, but not as annoying.
Thanks. I'll download the GPRS tweak program. Will that alone help the situation a bit? All I need is the voice capability, I won't use GPRS, only the GSM voice -- for internet browsing I may get a WiFi SDIO card from SanDisk.
I thought that changing to some other Radio software would help, but I heard on this site that changing the OS is risky. Can you tell me what I could do to get some a better connection, perhaps guide me through installing a correct version of Radio?
I haven't had this phone for very long, so I'm unsure if I should attempt to upgrade/downgrade.
-Greg
Greg,
I think the tweak program will help things a bit.. As I mentioned I am able to get signal seemingly quicker when I have it set...
I was pretty paranoid about OS upgrades, but I've gone through about 4 versions so far. This week is the first time I ventured out to use a different radio version than what comes with the upgrade.
Try the tweak and see how things go for a while, and then make your decision to upgrade your ROM...
I always seem to get the rom updated, 3.27 radio. DCD, Dizzle, or any other rom produces same results. Calls/SMS work fine, even 1X data works. Anytime it goes to EVDO it can't transmit data. I get the dreaded 1012 error. I've run through all the threads here, and i have no idea where to go from here. Any suggestions? If i force 1x, it works consistently, and the signal is at about 5 bars constantly. If i enable EVDO, the signal drops to 1-2 bars in teh same spot. I can reproduce this all the time.

the 1012 error is probably due to programming: mobile ip profile 1, username and pass. you might try assigning yourself a new NAI by creating a new username on sprint.com (from your pc)
as for the signal strength... you are seeing 2 different signals. EvDO and 1xRTT are on completely different bands, and should be different signal levels. However, the sprint evdo icon replacement (you know how the antenna icon on the sprint build shows more "bars") is misleading - it has a max 7 bars for 1x and max 4 bars for Ev (i think - going from memory- im at work)

I can't change that info on the site, it's a family acct and my dad has the info for that. I am on the phone with someone now, and it looks like they are changing some stuff on their end. we've troubleshooted the phone, she says if this doesn't work, they're blaming the phone. I'm not ready to blame the phone yet
EDIT: She fixed it! apparently she disabled and re-enabled my data services and that did the trick. Cool info about the signal strength indicator, i thought i was only getting about 50% EVDO. Apparently i'm getting 2-3 in here, and i got 4 when i went to lunch so I suppose it's about right.

tell them to assign you a new NAI. then run IOTA and let it populate the mip profile with this new info (could take a few hours after they assign new NAI before its all the way thru their system)

I'll keep that in mind if this ever happens again. It's fixed and working like a champ now. I am curious as to why this happened though...it has to be something with me flashing all these roms and whatnot. If i keep flashing ROM's is there any chance that this will happen again?

officially: i dont know
unofficially: i think that as 3.16 is an internal, testing rom, it does some strange things. the radio is a major upgrade, and the official updater goes through a longer process. i first upgraded using the real RUU, and i have never lost any settings. but something about breaking the update down into parts and flashing the radio individually wipes it. that said, i dont think we will see this again, unless we see another upgrade that is this major.
I recently upgraded to wm6.1 and added the agps fix which has been great. However, my network speed doesn't seem to have picked up the way I was hoping for, maybe I was expecting too much, with the Rev A upgrade. I live in Charlotte, NC and have verizon service which I believe has a Rev A network so my question is, Is there a way to check and see if I am indeed running on the Rev A network? Have I missed a step other than just applying the upgrade?
Basically you wont see too much immediate improvement, but The most reliable way I know of to show you are using Rev.a is to tether and run a speed test. Look at the upload speed and if its over about 112kbps, its Rev. a.
But if you are on Verizon's network and have evdo coverage, you have rev.a capability. Speeds depend too much on tower traffic and how many/what kind of lines connect the tower to the net. Just rest assured it is working when available.
Ok, thanks for your help
Visit www.dslreports.com/mspeed using PIE
Make sure you have 4 bars with EVDO to get the most accurate results
You should get speeds at and upwards of 800kbps (I routinely get 900+ and sometimes bursts above that)
maybe....

On my titan the icon is rA where ev or 1x used to be .....alltel
I recently upgraded to DCD 3.2.6 and Radio 3.35.04
I've noticed horribly slow internet, especially when tethering. We're talking dial-up speeds OR WORSE!
I've also noticed that the tethering seems to disconnect VERY frequently from the computer. 2-3 times in a 30 second period sometimes!
I'm on vacation and am trying to use my computer and phone to plan activities but it's so slow it's useless and worse is making my girlfriend irrate! Any ideas? Suggestions? Tweaks?
Thanks! This is driving me crazy!
PS - My computer is running Vista... but it used to be great.
who is your service provider? it could be a bad cell tower spot you are in, go into settings>>>phone>>services>>>mode of operation>>>get settings>>> and select EVDO only, this may help lock it into higher speed service, just remember to put it back into hybrid when u start travelling so it will switch towers freely...also upgrade your radio to the same one listed in my signature
Tried...
I change the mode to EVDO only but it doesn't seem to have helped. I also ran a *228 as well, just in case I wasn't getting the right towers. I'm using Verizon Wireless.
Still dog slow.
I can't upgrade the radio at the moment - as I in Las Vegas and only have my Vista laptop with me.
Although... I DO have a 2MB SD Card with me... but I've never upgraded from a card before... just from a USB connection.
Try changing the DNS servers. I had a huge difference in speed after I changed my DNS servers from Sprint's to OpenDNS.

So, I S-offed my phone a while ago. I finally convinced my wife she should let me S-off her phone a day ago.
After S-off, I flashed the newest ICS leak (2x to make sure the RUU ran properly) and then flashed the stock deodexed rom that Scott posted.
That way she can have root, and I can remove some of the bloat apps she doesn't want via titanium and call it a day.
However, her phone is having some serious issues with 3g constantly toggling on and off while on wifi. (We don't have 4g in our area). I thought it was an issue with the kernel not flashing properly, so I wiped, and flashed it seperately. Still no change.
I reran the RUU 2x, and reflashed the stock leaked deodexed rom from Scott.
Still not changing the results. Her phone is running at least 10 degrees hotter from the constant radio toggling. Phone is reporting the same kernel and radios that I am.
Further investigation reveals that my phone is running on EVDO Rev.a, and her's is running on eHRPD. Running speedtests on the phones shows her getting 2-3x the data speeds of my phone while sitting in the exact same spot in the house.
So... any idea what's going on here? Technically eHRPD is better for data speeds as I understand it. However, if her phone is running at 104F and it's killing her battery it's not better.
For reference, my phone is also S-off, with the newest radios and kernels. I am running Rez Rom 2.1 which is a Sense 4.0 rom vs her stock deodex. As far as I can tell, mine being Sense 4.0 shouldn't be influencing the data connection like that.
Any thoughts would be really appreciated.
This is interesting,
where are you seeing which network you are connected to?
System settings> About Phone> Network.
It's listed there under Mobile network type.
Update:
I flashed her phone to the same Rez Rom s4 2.1 my phone is on, and it seems to have stopped the toggling issue.
She's still on eHRDP vs. my EVDO rev. a and the speed difference is huge.
Any ideas how to switch over to eHRDP?
If you have the 3G icon on both phones, then both phones are connected via EVDO Rev. A.
eHRPD is essentially an authentication protocol that allows switching to LTE when it is available.
Even when toggling LTE off in the network settings, the phone still connects via eHRPD. On the Droid Charge with a ROM with TSM parts, one can manually change the network selection. If you want voice, you need either 1X only mode or eHRPD 1X mode. If you only care about data, then there is an EVDO only mode. There is also the ability to force EVDO Rev 0 and still have 1X, but Rev 0 is even slower than Rev. A.
I don't think there is an easy way to change these settings on the Rezound (I'd like to know if there is.)
Generally, eHRPD is known for having data drops because of some network authentication issue. I have tried EVDO Rev A only mode and had less issues, but I have not tested this in a 4G area. Verizon may have fixed the eHRPD issues or they may not have.
Concerning your problem, I don't really have a guess what the problem could be. I can confirm that I have the CDMA selection in the network settings and that Network Speed confirms my network as eHRPD.
Procede with caution, since I am a Rezound noob: I would suggest running the RUU again along with the radios to see if it was a wonky radio flash. I can tell you that for some darn reason, I seemingly had to flash the radios on the Droid Charge several times in order fix some radio problems I had...

Beat me to your post. Are you in a 4G area? What speeds are you getting? I've never seen a phone get stuck on EVDO Rev A only mode with 1X still working. Try toggling 4G on and off and rebooting.
We don't live in a 4g area.
Update again:
My phone has switched over to eHRPD and things seemed to have calmed down. I did reboot it previously, and togggle airplane mode a few times and it didnt care about changing over from evdo.
I guess the weird toggling issue on her phone brought to light another issue that might be unrelated?
Thanks for the insight xdadevnube
