3g times out?

I was wondering if anyone else has/had this problem. My evo tends to time out on 3g, especially when I download a rom. The 3g indicator just goes dark and will stay that way for a couple minutes. It wouldn't be a big problem but I don't have hi speed where I live so every Rom I download is through my phone internet. When the 3g times out it causes the Rom download to fail. Has anyone else had this problem and what can you do to fix it? It's irritating having to download a rom 5 plus times

This only happened to me when I was on stock. Now that I'm on a custom ROM, it doesn't happen anymore. I notice you are on a custom rom, so I'm sure that's not the problem.
It may be a coverage problem. It also happens to me when I'm switching from 3g to 1X, so that may be it.

The area I'm in has almost full signal. I've actually experienced this more on custom roms then when i was on stock.

Have you tried flashing the more updated radios, etc?

Just did. Will report back to see if it helps

Any update on this? Just was curious if this did the trick for you.

My 3g does not work on roms outside of stock sense roms. I've read where others says sense roms always show 3g even if you are getting a 1x signal but my wife has an evo 4g, unrooted, as well and my 1x is way slower then her 3g signal. I 1x signal won't load web pages in most cases. I downloaded the most recent OTA and then flashed a rom after words but still no 3g.

Any update on this? Just was curious if this did the trick for you.
After I flashed the new radios etc. I tried to download a rom overnight. When I got up it said download failed, then I remembered to update prl and what not. After i updated things were ok until I tried out my 4G. I was having major issues with it not downloading. It was extremely slow. I was using the shooter ROM when these problems started so I flashed another ROM and haven't had any problems so far. Is it possible for a rom to affect 3g and 4G performance?

This isn't necessarily true. Most custom ROMs show 1x. However the stock does not. Also, 1x should be slower than 3g.

Sorry if I wasn't clear but that was my point. Thats what most people "say" about roms showing 1x and my 1x is slower then my wife 3g so I know its not that we don't have 3g in our area, its the rom. Right now I'm using R2R-green-R3, which has a 4g LTE icon and faster then the 1x rom I was using before. I flashed the honeycomb theme over it looks great and works great!

It shouldn't be the rom causing you to get 1x, have you tried updating prl/profile? I've run multiple custom roms and never had a problem. Areas where I know get 1x show it, but areas that get 3g show 3g and have 3g speeds
Sent from my PC36100 using xda premium

I did up date the prl/profile but still no 3g. I'm at 3g speed now so its not a problem. Maybe I did something wrong on the other rom?

Data keeps switching between 3g and H+

Ever since I flashed my phone with the wicked rom .. my data has been do constantly switching between 3g and h+... I have my network type set to wcdma only and I have a strong signal but it still drops down to 3g
Before when I was on the stock rom it never did that.. I even had my network type set to wcdma preferred ..
Anyone having the same issue ?

That's completely normal. It only shows h when your data is fully active. Its a good thing. The only difference is now your phone is telling you the truth.

Oh is it normal ? I didn't know since on the stock rom it never did that ,always displayed 4g.
But what would it drop to 3g if I have a strong signal always

Yeah dude. T-Mobile does that they call their hspa+ 4G. Technically anything that is not 3g is considered 4G. The reason you are seeing this on your new rom is because the stock tmobile rom will only display you in 2G or E for edge. Or 4G for 3G and HSPA+ otherwise known as 4G. The majority of customer roms will tell you what you are currently on.

ROMS not keeping 4G

I have been flashing for years and i just came over from ATT SG3 where i had no problems flashing and retaining 4g, but now on tmobile every rom i flash all i ever get is 3g and never 4g .. only for a brief second. the reason i came from ATT was the unlimited data.. can someone please assist as i used CM10, AOKP, WICKEDv5, blackjelly..... i cant figured it out. any help would be appreciated.

Hmm i would think Phoenix should have good service. Maybe you should Odin back to stock and start all over. Radio is the only reason i can think of that would affect the speed.

How are you distinguishing what connection you are on? Many roms will show H+ instead of 4g

I'm on stock. Rooted yesterday and download speeds seem slower now. I will do more testing this afternoon.
Sent from my SGH-T999 using Tapatalk 2

well on the t-mobile variations the best you can get is H+ and most ROMs show that. other than that, try using a different kernel. that was the problem for me where my data wouldn't even work sometimes.

It looks like op knows the difference between 3g and 4g/H+ he noticed that he only gets 4g for like a second here and there and that's it.

I had a similar problem. What happened with me was one day I went from great 4G (HSPA+) speeds 80ms Ping, 25MB Down, 4MB Up to all of the sudden a 1200ms Ping with 0.05MB Down and NO UPLOAD.
Turns out it was a problem with some towers in my area. Took T-Mobile two weeks to fix everything. Not sure if that is what's happening here but it could be possible.

Same issue AOKP Build5 4.2.2
I too have this same issue with AOKP build 5 solid 3g but no 4g (H+) (tmo)
Stock however has solid 4g (chandler AZ)
gonna try CM and see what happens there.
Also gonna research radios aswell (really really really liked AOKP just didnt like being back on 3g)

Why am I only getting 1x speeds on custom ROMs?

I have a epic touch 4g flashed to cricket and I was on wondering why I get 1x on custom ROMs but stock ROMs are just fine. And when I do get 3g the data acts weird and cuts on and off.
Sent from my SPH-D710 using xda app-developers app

It might not be that you are even on 3G but sprint has this little habit of lying on their stock ROMs by making it so it always shows 3G even when connected to 1x. The devs on xda have made it so that in ROMs shows the true connection such 1x/3G.
A good way to verify while on stock is to go look on the about phone to see what you are connected to or use netmonitor/speedtest to see what connection you are on.

I had a ROM they showed real speeds and I was on 3g. The ROM was basically a slightly modified stock though....

another welcome to sprint thread.. my speeds are always at 1x no matter what rom/modem im on because of my area
Sent from my SPH-D710 using XDA

Well first crickets 3g doesn't work very well on sprint phones, if you want real 3g you need a cricket phone or be on Sprint.
Data does work on touchwiz roms though, and if you want aosp you have to flash a fix to get it to work on those, but it won't be even close to 3g unless your lucky.
If you don't have the fix its here http://forum.xda-developers.com/showthread.php?t=1479175 use the ics one for ics and jb.

I've gotten 1.6 Mb/s download speed on aosp jb with Cricket, although average during the day is more like 800Kb/s. Area, PRL, signal strength, etc play a huge role as well.

From 4G to Edge, No 3G

Why is it that I only flip between 4G and Edge but have no 3G. Does anyone else have this or is it a t mobile network thing?

It depends...are you stock, rooted stock, or custom ROM? The reason I ask (regardless of settings) is I never got 3G on stock. After I rooted and used Kasper's AOKP nightlies my phone would use Edege, G, 3G, and 4G. Where I work the signal wasn't so good so locking onto 3G was tough but with the J4 and JA modems now I can consistently hold 3G with the AOKP ROM.
My opinion is to check for the newest modem which is JA (Jelly Bean update) if you are rooted and use that from the modem download thread here on XDA. If you aren't rooted wait for the upgrade and you will get that modem regardless.
However, AOKP ROM most likely works differently so you still might not see 3G if you are stock JB that's why I think we would needa bit more info.

I'm stock everything for a change lol. I also have the latest jelly bean update. I haven't seen 3G once on the phone since I've gotten it. It's really weird...

Your second guess is correct. Tmo is edge or a highly evolved version of 3g. It has nothing to do with stock vs rooted. The modem or kernel may help a little depending on what you are running. If you are in high speed 3g area aka 4G be happy.

Yeh it just gets annoying when I drop straight from 4G to Edge. :what:

T-Mobile uses HSPA+ for their current 4G network, which is just an extension of their 3G network. So, if you're on stock, it will jump from Edge to 4G, since T-Mobile's 3G and 4G are of the same technology.
When you're rooted, it will show 3G while your phone is at rest. As soon as "heavy" loads come in, it will shoot straight 4G. At times of very light loads, your phone might stay on 3G, but it's rare.
Bottom line, you're phone is perfectly fine when it jumps from 4G to Edge. Stock won't differentiate the two (3G&4G).

Well described... Thanks for clearing that up. Hopefully it helped some other people also.
