[Q] 4G issues, had to go back to Eclair! - Epic 4G General

While running Stock EB13(rooted with camera fix) I had to go back to Eclair because my 4G would not connect. I have always had a strong 4G signal at work but all of a sudden it would not connect. I tried rebooting, wipe, Odin, and Samsung update app, and nothing. I figured Sprint's network was to blame, so I called.....no network outage, no cell tower problems, zip. Thus I Odined my Epic back to Stock eclair, and bam 4G was up. Has anyone had a problem like this?
Edit: Ok so as of today I went to a Service Center to order a new phone, Sprint customer/tech support tried their best but my 4G at work would not consistently connect. However, as soon I got out of range of the tower close to work 4g connected and reconnected like normal. Which leaves me to believe that the tower or antenna is acting like a B**CH. Well see once my new Epic is in!

I use a custom EB13 ROM and 4G is fine; using WiFi Tether, too.

I was also running Wifi Tether on EB13 but no custom ROM or Kernel. I'm in North Chicago so i was wondering if anyone else was having 4G issues.

You might have had an issue with your modem. You could reflash/reodin the modem only. Also you could try updating your prl settings through the menu settings. If that doesn't work then update prl using the manual method in the development section.

4G problem

I did the fix and i am on stock updated all the way from one of the threads in the dev section and before 4G worked with the old radio but cut out all the time So i decided to do this fix and now the 4G connects for about a minute and it disconnects and i am in an area with excellent 4G coverage. So if anyone knows of a 4G connection problem in the Kansas City area please tell me or if it is just my phone tell me how i can fix this problem.
Edit: It appears that 3G cuts in to do data instead of 4G because as soon as it cuts out 3G uses data.
Edit 2: Now if I go in to Setting>Wireless & Networks>4G Settings It says fair - Poor connection, Assuming because i am inside, but i am not connected.
Edit 3: After disabling mobile data in the network settings it now holds the 4G connection well but now i have to wonder why 3G would over take 4G while it is on.
I been having 4g problems since the recent ota update. I hardly get 4g and it's considerably slower.. I'm running full stock with no root. What fix is available?

EVO Not showing 1x / False 3G

Ok so I have been messing around with the evo and doing a new rom for the whole cricket thing.
One thing i have noticed while doing this is that the EVO DOES NOT drop down to 1x at all. So i decided to write a 1x PRL to the phone. The phone reports that it is ON 3G network. This is not possible and I think that is wrong. Sprint has the phone reporting that it is 3G even though its on a 1x network.
If his has been discussed please let me know thanks.

Sorry to deviate from your original message but is there a way to force 1x? I'm assuming 1x uses less energy than EVDO/3G; so if true, it would be beneficial to switch to 1x when idling/display is off. Maybe tasker or juice defender already does this?
Edit: On CM6 I hit 1x from time to time. At least the status bar reports it as 1x. Could be a Sense/HTC bug.
Edit 2: It seems that Android doesn't have a API for 3G/2G toggling. Sucks.
No your fine, Yes CM does go to 1x. This isnt based off a sprint rom. Its not a HTC Sense issue because I had ported a incredible rom a while back to the phone and it would drop to 1x. I just tried a new port for 2.2 from the incredible and its doing the same thing.
It is possbile that it could be a HTC Sense Bug in the 2.2 Froyo. But i really think that Verizon and Sprint are not wanting it to drop to 1x. Wich i think is wrong.
The way i forced it was to load a 1x PRL on the phone.
I'm connected as 3G "False" as i checked the speed now and I only got 39.62kb wich is far from the 1565.1kbs i checked before switching PRL.
Maybe you already knew this, but I'm pretty sure that for a 1xRTT network the 3G icon in stock htc sense roms simply greys out. At least that's what I remember seeing in the manual. When the phone is connected to 3G the icon turns white.
I don't know - I'm almost positive that I've seen a 1x symbol in my status bar instead of 3g a few times. It's been a while though...
Well from what i see thats not true.
Im on 1xRTT right now. The icon is a solid white.
Even if that was the case and it should grey out. That is completely deceiving. It should accurtly show it is on the 1x network.

sorry - who was this to? Also, I know there's a 1x symbol in the framework - it's got to be there for a reason, right?
OK I just checked the manual and it has a 1X icon. You're right.
Edit: The com.htc.resources.apk where sense signal icons are located contains the images for 1X so maybe it's something in the xml's that prevents the phone from either correctly notifying a 1X signal or bypassing the connection all together. HTC obviously intended for the phone to connect to 1X if they took the time to sensify the images. Strange.
Yes HTC intended for it but thats not the case. Has anyone on sprint successfully dropped to a 1x Connection ? Here is what I notice if im not forcing a 1x connection.
If it looses a 3G connection, it does not successfully drop to 1x. It just looses 3G all together then tries multiple times to go to 3G if it doesn't succeed you loose internet.
If you have a 1x prl it loads 1x but shows its a 3G connection wich is not true at all. This is disappointing.

ummm...yeah - like I said in my prev post, I've seen the 1x icon appear on my phone in parts of nj where I wasn't picking up 3g.
What ROM are you using ?
OK Im going to grab my friends Evo tonight that is on a sprint a force a 1x connection and see if his shows accurately or not.
I assume your custom PRL is forcing a 1X connection on sprint towers and not verizon or something? The phone may only show a drop to 1X if on sprint's network. If you are on verizon or cricket or something it probably wont indicate 1X.

I was either using stock, or an older version of baked snack.
Its not a custom PRL the one im using is a cricket prl. Made only for 1x network. It does not support EVDO.
Sprint has a few 1x PRL's only and I will load his phone with it and test it.
That doesn't make sense. The phone being on cricket or any other service would not make the phone report its on 3G all time. I flash a lot of phones to cricket. Like i said before this is a Sprint Rom issue. I loaded it with a incredible ROM and it successfully drops to 1x connection.
fachadick,
You might have been using baked snack rom.
Im checking tonight with the service on sprint.
So far its confirmed.
Two people with HTC EVO's on sprint.
One (Me) on with evo on cricket.
We forced all three EVOs to work on 1x connection only. All three of them are showing 3G icon but are only getting 1x speeds. This is very deceiving.

The reason I say it might not work on a PRL from another carrier is because when I am roaming I get a triangle above my reception, but the data icon remains 3G if I remember correctly. The actual data connection is only 1X because of roaming agreements, so what I am theorizing here is that the phone only changes to 1X when you are on an authentic sprint network and the connection drops to 1X. This is probably built into the rom, which is why it works for other phones, but not the EVO.
Because you are using a "roaming" PRL, I would think that the phone doesn't trigger the change to 1X icon just like actual roaming with a Sprint PRL. That's my hunch.
Yes i understand what you are saying, and yes that is plausible.
But doesn't explain why when we force the sprint ones they do not change to 1x ? I can force any other phone to 1x on the sprint network.

My phone crashes when entering a roaming area

I have a G2 running Cyanogen 6.1.1 with pershoots latest kernel and when I enter a AT&T roaming area my phone crashes and reboots itself. God forbid I try and use google maps or places. I noticed if I uncheck the "national data roaming" the phone operates as normal but ofcourse I don't have any kind of data access.
Has anyone else noticed this behavior?
Does this happen with the stock rom? I wouldn't know because I been running cyanogen from day 1.
The phone has some serious issues when roaming. Even after I came back to the home service area I had no signal at all until I reboot the phone.
Due to buisiness I am going to be in that area a lot and really need my phone to work.

I live in Maine, and this is a valuable feature when we travel inland. Has always worked flawlessly on BB, MT3G and HD2. My boyfriend's Vibrant picks up ATT and Unicel without issue. Unfortunately, I was unable to connect to another network (voice and data were nil) on the stock rom, and I had to go airplane mode to get signal back when I knew I was back in the TMo area. Haven't tried it on CM yet, but pisses me off to no end that a Vibrant gets better signal and service than my G2. (And that a necessary service for our area doesn't work as it should)

No evdo connectivity only 1x

Downgraded to calkulins v1.7 since i was having issues with 1.8 and now i am not getting evdo connectivity at all. My phone only connects to 1x. Ive tried restoring my settings when i do ##3282# edit data profile and evdo. Im not sure what else to do. Ive flashed 3 different roms and nothing helped. What else can i do?
Sent from my PC36100 using XDA App
Go to settings, wireless & networks, mobile networks, mode of operation, and chose evdo only. This fixed my problem, hopefully it will help you.
I have no option to select mode of operation. I am unrooted now and back on bone stock ROM and still have this issue so I am not sure what is wrong. I am currently chatting with sprint to reset anything on their end. However, it still only connects to 1XRTT
try flashing 1.8 back and change the operation mode to hybrid. double check with ##3282# to also make sure the evdo setting is on automatic.
Sent from my PC36100 using Tapatalk
i just fixed this problem myself. go back to calkulin's evio 1.8, and change setting to hybrid. to see if it works, type ##3282# into dialer and choose view mode. go to evdo settings, and make sure its set on automatic. if not, then:
retrieve your msl (free app in market msl reader) and type the same code in, but choose edit mode. type in your msl, and go to evdo settings, and change to auto.
Ahhhh! I don't have this option :/

Changing to EVDO only helps with 1X, but I found out that the setting to EVDO only will not allow incoming text or calls. I had to put it back to Automatic.
I've tried everything everyone has posted so far. Changing to EVDO only and automatic and all that stuff. I took it into the Sprint store today and they tried telling me it was on 3G since the icon was showing that. I told them the evo icon never changes to 1x even when connected to 1x. She still didn't believe me. So I downloaded a few apps that showed my phone only connected to 1x and she downloaded the same app and it showed hers connected to EVDO. She said she couldn't trust the app and then she compared my phone internet load times to hers and mine was actually faster so she still wasn't convinced. I explained that the 3G is on a higher frequency than 1x and being indoors she may have a poor signal compared to mine. Also I told her that everyone in our area is probably connected to EVDO, thus slowing it down, versus just me on 1x, so I had better speeds. She said that is very true, so she ordered me a new Evo that should be here in a few days.

THIS WILL GET YOU 3G
but you will be constantly roaming
try it out and let me know if it works for you.
##775#
search for 00001.prl and change it.
commit changes and it will restart
give it about 10 mins to get connected right and do a speed test.
i was getting only 15-20 kbps using the latest sprint prl.
i changed to this modified prl and im getting 1700-2200 kbps
i think sprints prl's are messed up..
What test can o perform to prove that its versions network I am using after this hack? An iplookup says I'm still connected to sprint.

Roaming and EG22

Anyone having any luck with Roam Control on EG22? I'm running the EG22 w/ EG22 modem. Everything looks to be working fine except for one huge glaring problem...roaming. I have all the roam guard nonsense turned off. I hit Roaming Only, I get the little triangle and even see it in the debug connected to VZW but I never get any data connection. I've tried rebooting, etc.
I would love to hang out on EG22 but without roaming this thing is worthless to me. At work I have to force roam since Sprint data has been dead downtown for over a year.
Works fine for me
remember, data won't show if you're connected to 4g or wifi.

Hmm... no 4G or WiFi here. It just shows the triangle with the signal meter, but of course there is no data connection.
I flashed the DEODEXED version by decadance. What version are you using? are you using the EG22 modem? I haven't tried to flash an older modem yet.
Make sure you have data enabled. hold the power button and then click data network mode.
Tried with rc 1.4 and it worked, the 3g data symbol doesn't show up till you request for internet. Both time I tried took 1 min to handshake.
I am using prl 11114 and my suppose to be 3g data roam speed is at cdma speed dl is caped around 120kbps on verizon full signal bar.
Sent from my SPH-D700 using XDA App
the newest RC works for me, but the modem crashes and reboots every time I go into roaming, but it reboots into roaming fine so I haven't really worried too much
I checked all that. It just doesn't handshake for some reason. I remember this same issue on the very first Froyo leak. Weird thing is I tried the roaming on the very first GB leak and it worked just fine.
I'll have to flash around some modems, try a different release of EG22 and see if I can get this working. This feature is a huge must for me.
Got it working... ODIN'd to this version of GB and it worked first shot. WOOHOO!! Loving it.
