So i have rooted my phone a while back, and been flashing new roms back and fourth , but not sure why recently after a couple of weeks, i have seen my 3g signal drop without me doing anything, on the same places were i usually get perfect 3g signal,
i updated the radios to recent ones, update the profile , PRL profile etc so see if these was the problem that 3g drops all the time,
so i have flash myths , cya mods roms, MIUI , and evry other sense roms like HD SACS and fresh evo etc and i even try AOSP roms to see if the sense roms was the problem, but with AOSP Roms it even drops more,
example of what i mean:
i will be using the internet were it takes forevr to load cuz 3g dont kick in,
than out of no where 3g works perfectly for like 5 to 10 mins,
than after a while i try to use any application that uses internet like facebook, pandora, youtube etc, the 3g starts acting up and doesnt kick in , does this evry other 10 mins which its annoying the crap out of me.
PLEASE IF ANYONE CAN HELP ME I WILL EVEN DONATE $20 TO 30 BUCKS FOR YOUR TIME BY PAYPAL.
NOT SURE WHAT OTHER OPTIONS I HAVE, AND I REALLY DONT WANT TO REPLACE MY PHONE AND IM PRETTY SURE I CANT BRING IT TO SPRINT TO FIX IT CUZ ITS ROOTED, OR CAN I?
THANKS
Here is the best thing to try for starters.
Start completely fresh.
Download this zip
http://www.mediafire.com/file/ikylelx99c49133/Calkulin's_FORMAT_ALL.zip
flash that zip from recovery and it will format everything without a doubt.
Then flash a rom like this

stock rooted ruu - simple and no modifications.
If you are still having issues after this, then it is possible that you are having hardware issues.
It wouldn't hurt to try updating your radios as well
http://forum.xda-developers.com/showthread.php?t=715485 - the combo one at the top should get them all.
+1 those are the best suggestions than I think can be given to help with your situation. I had the same problem on my hwd 003 evo sent it in and got a hwd 004 speeds were better I think it was a hwd problem cause I couldn't find a fix.

i just try this like 2 hours ago, its going fine for now but still dropping the 3g couple of times, i just want to see how it goes by the end of the day...because this phone that i have its a replacement cuz my original evo i lost it, hopefully i didnt get a evo that has a hardware issue even though it was working fine for the first months, till now.
thanks again for ur help and ill keep u updated of how it goes and test it for a couple of days.
so i use it over the weekend, and after a day it starting acting up again, i was happy when it work almost for a full day and than it starting acting up where 3g wasnt kicking in, thanks for ur advise and i guess i have to replace this evo.
you might wanna try going to a Sprint store with service center, maybe they can figure it out there, as you've basically tried everything one can do at home to try and fix it, and are still having problems.

Here's one to accompany that. It may not even be your phone. Call *2 and ask if they are having network issues in your area. Mine was doing the same thing after a storm (we had tornaders...yes, tornaders...live with it). It was back up withing 48 hours, then again, I reported the issue.
I'm sure they have some pretty good monitoring systems in place; however, if the guys behind the NOC are anything like the guys here at my work...well I won't say anything, but you can piece together the picture.

nobody else i know have 3g issues, because i have ask my friends with evo's and my roommate to let me see there evo and check if the sprint network just acting up, but is not cuz there phone is running good. but it seems like i start getting normal 3g signal when i first flash a rom, than after a couple of hours or a day it start acting up, its annoying as hell cuz i could be in the middle of doing something during the day and when i need my phone to work with 3g, it start acting up,
thanks though for the suggestion, not sure if rooting the phone would effect the signal problem,

Just because you see it drop to 1x doesn't mean anything. That means that sense doesn't want you to know about it. so there is no icon for 1x since aosp is different and doesn't lie it tells you the truth. I thought things like this from time to time until I did this. Flashed stock. Speedtest... sat in the same spot flashed CM, speedtest. Both were about the same.. some tests were faster on CM then sense and some were faster on sense then CM. I get my email... and my market downloads never fail... So I can't really complain.
I have done some searching so please don't flame me, I couldn't find a specific answer.
I live in New Orleans (No 4G yet) but I am currently in Pittsburgh going to have a kidney transplant on Thursday. I really want to get my 4G working since it will be my only source of internet while I am in the hospital.
When I turn 4G on, it constantly cycles "Turning on" and "Turning off"
This is what I am running:
Rooted Evo Hardware Version 0003
Android 2.2
Baseband 2.15.00.11.19
Kernel 2.6.32.17-gee557fd [email protected] #15
Build number Calkulin's EViO 2 ROM v1.7.5
Software 3.70.651.1
PRI Version 1.90_003
PRL 60674
Wimax Version 4.6.2.3v27167
Thanks in advance for any help. I am a bit desperate since I will be in the hospital starting Thursday for about 2 weeks and still in Pittsburgh for about an entire month. I would love to get this working and I think the constant toggle of 4G is going to destroy my battery life and I can't get it to stop.
Thanks again.
I had the same issue and it was because of adfree and an old titanium backup that was corrupt. Mine was doing exactly what yours is but I was on rls5. I know it's not the rom because I am back on it and don't have that problem anymore. I would start from scratch but flash back to a stock rom first to make sure everything goes back to normal. In my case I had a nandroid of stock right when I rooted a few months back. Hope this helps
Thanks, I'm downloading Sprint Lovers right now and am going to give that a try. The last time I flashed, I restored only my apps, not system settings using Titanium. I always do a fresh backup right before I flash.
I've been so excited to try 4G and now I get nothing. Frustrating. I will try your advice and let you know. Thanks again.
here is my guess....
you are in a hospital...
they have some very intensive strong machines that put out so much interferance. most phones have problems getting a good phone singal in a hospital. you maybe fighting non-winalbe battle.
you need to talk to the nurses about alternative connections.

In my case even just installing apps and no data caused the problem. Once I started over again, it went back to normal.
Make sure you update you profile a few times in a row after flashing new roms too. It has been known to cause problems with the radio not connecting.

Thanks but I'm not in the hospital yet, I will be on Thursday. I was driving last night in downtown Pittsburgh where I should be getting a great signal and no 4G.
I will try the sprint lovers with nothing installed or restored and see if I can get 4G to work. I will definitely update my profile a few times to see if that helps. I just checked my RSA key and it is still intact so I'm glad about that.
Going to the store now so I will try it some more while I'm out and about.
Thanks.
Before you do all that, try turning it on with a 4G widget, it worked for me.

Make sure your wifi is off or 4g won't connect, as the phone prefers the fastest connection available.

Ok, progress:
Flashed Sprint Lovers Rom
Got 4G to turn on
Now it scans, attempts to connect to Sprint and does not connect
I checked my MAC and compared it to the 4G MAC under the battery and they match.
Any ideas?
Ok, walked to the window of the hotel and I got it to connect for 1 second then it dropped again and I cannot connect it anymore. I got super excited for the one second though. I don't know why it would not connect on my other rom. The hotel must have something going on to not let it connect so well.
Welcome to the world of 4g. Its great when you've got a good signal and awful when you don't. Coverage is very spotty and large concrete and steel buildings are its enemy. I've been in hotels that I've gotten great coverage and then walk across the hall and nothing. At least you know its working now, hopefully the hospital will have a better signal.
Restoring my apps now and hoping Titanium doesn't blow it up again. I'm going to walk outside in a few minutes (brrrrr) and try it out again. Hopefully I will have better success.
Apps and system settings restored and I still get it to turn on, now it's time to go outside and see if I can connect. It stinks that it wouldn't work with the other rom.
Anyone know if they can connect with OMJ's rom?
in weak 4g signal areas I had better luck connecting with cmwimax 6.1.2 alpha 3, give it a try
I use myn warm RLS5.... and 4g works fine.

Thanks guys, I will check them out.
Thanks for the help everyone, got it to connect in the lobby and download speed was almost 3mb. Then I tested it again and it was .5mb. It is spotty in this hotel so I will try it tomorrow when I am out.

How is this rom, I have tried some CM roms in the past (the ones that don't have 4g working) and they were pretty cool but buggy. I like stable roms.
Let me know, maybe I'll make the change again.
Hey guys my 3g has been messed up for a little while now and i dont no whats causing it... i have flashed several roms and has not helped at all... currently running ext4 syndicate rom (newest version) and i have tried several kernals right now vision kernal is what im on. My download speeds average around .40-.60 and upload speeds go from .15-.20 using speed test. I have 5 bars of service sometimes it will go to 6 bars so its not signal. i dont no what is causing it, i have tried just using a Fresh rom with no apps downloaded and same results. im just lost, any ideas? and yes 3g is on and showing
My 3G had been exhibiting all kinds of funky behavior for at least a solid month. I was starting to think it had something to do with the roms and kernels, but now I'm leaning toward sprints network. Just look around the forums, some people report great 3G speeds and others report crappy speeds and odd behavior.
I'm in the middle, sometimes my 3G is fine and other times it just stalls, drops to 1x and just plain sucks. I have no explanation as I've tried 4 different modems and I see similar behavior. That's why I'm leaning towards sprints 3G network has got some issues.

Yes, I too think it is Sprint. I get great speeds off my Airave, then decent speeds a mile away, then go 3-5 miles away and it almost hangs, just sits and really crawls. Then a week later it will all change.
If you continue to have issues, flash the EB13 modem.

ok ill try that but one problem lol,,,,,my cord that came with my phone to connect it to pc via usb broke. i went to the sprint store to get another and they are out, ofcourse....anyway i cant use odin til i get my new one so id have to flash the rom though a zip if possible? which i dont think it is? if there is a zip i can flash of the eb13 could u possibly link me please? then i can go to it by my phone download it and BAM be done with it. thanks again for all your responses. and to the above post, yes my 3g has been goin in to 1xmode as well with 5 bars of service... weird
Any micro USB cable is worth trying. Another phone cable, some USB hubs, cameras, etc. You may have more cables than you realize already.
I have the same problem. After long conversations with sprint tech support they fixed the tower near my home and it worked great for a day and the weather went bad so it crapped out again.

I've used that one, ec05, di18 and now ee03. For shats and giggles, I'm going to take your advice and also try dk28's modem.
More and more everyday I feel its sprint tho.
I am currently tethering over a 4g connection, and my internet is working fine, BUT I have a complete LOS for the cell signal. I think this could be a very important fact because we should be able to know some things by the fact that WiMax is working while the cell signal is altogether lost.
Hopefully, with this info, a solution is a little closer at hand.
Ok...when people say LOS do they mean Loss Of Service? Or Loss Of Signal?
Because if its the latter, that sht aint that bad. But if its the former...I'm glad I don't have it.

It is bad. People that get it have to reboot phone for it to come back and it kills battery life. Nit to mention missed calls and texts. It is a complete loss of service.
Sent From My Evo Killer!!!
Its 2 separate radios..
I had pandora going over 4g earlier for hours...but lost signal with a crossed out circle after about an hour. Pandora kept going but u couldn't make a phone call, ths.falls in line with the other poster. Im running eg30plus over latest 2.1 midnight.

As WhiteWidows stated, it's 2 different radios. The LOS people have posted over and over about is the ability to make/receive calls (which is what the OP posted about). The Wimax radio (4G) doesn't transmit phone calls. That's why you can do data on 4G and still make a call at the same time.
.....
Hi guys, this is one of my first posts but I've been a long time reader coming from the Evo 4G forums. I'm rooter using Zedomax v3 and experienced multiple LOS as well.
Last night I tried limiting the clock speed to 1ghz and setting the min at 400mhz. Strangly I now get slightly better reception and never had a LOS yet. Will continue to test out this theory and see if it's clock speed related.
I came about testing this since I ran mine at 1.6 for a while and not only would I get more LOS occurances, I would also get phone freezes lol. I tether and stream music a lot so wanted to keep it slightly underclocked to keep the temps down. Hope this helps as a temporary band aid for the LOS bug
It definitely makes sense that the two radios are separate...the point of my post was just to offer some more information to help figure out a fix.
If one radio fails while the other stays working, do we know that the problem is phone-related? Many posters have speculated that the issue may be on Sprint's end, so I wasn't sure if this info did anything to challenge or support that theory. Maybe it does nothing, though -- just throwing it out there!
Someone posted a log cat of a LOS. There's still some coding in the radio files that thinks there is a sim card. Says sim disconnected and result radio off

Hopefully a solution is found soon, I've seen similar issues posted on various android forums. Androidforums, Sprint community and here. Wish I waited a bit to hear more user experiences....

Has anyone tried editing the build prop to manually change the preferred network from wcdma to CDMA auto? Maybe that'd fix that issue
I have been on my current SGS2 stock out of the box for over a week now and have not had any LOS issues, or missing texts, or data not working, or missing phone calls, etc.....
I have been using wi-fi, 4G, 3G, have an Airaive, went to an area where there is no Sprint service and phone roamed fine and then went back to Sprint service when available.
I have been unable to replicate the LOS issue on my current phone through all possible ways of using it.
My first SGS2 was also fine until I rooted it which then gave me an LOS within 12 hours of doing so.
If someone has a another sure way to get an LOS, I am willing to try it on my stock, never rooted phone but I don't think there are any other situations I can try that I haven't already......
Time.I have went 3 days without a los then 2 in same day.It is all random
latest questions were in june, so im going to ask to get a more recent suggestion.
im having signal problems no matter where i go, and i live in between 2 towers close by, one has 4g and im getting about ~1500kbps when i should be getting over 5k. 3G speeds are 10-60kbps down, market times out, and internet is useless.
Ive been doing alot of flashing of different roms, dunno if something messed up my phone, or an internal hardware problem, or what.. but i shouldnt be getting piss poor signal and speeds on ALL roms. Ive updated latest radio, and did all that extra crap. Same poor results.
so for a peace of mind, i'd like to flash an official sprint pc36img that includes radios, pri,prl, etc Then i'd like to root that, install amon ra, and flash synergy rls1 again. So that way im having a new fresh start and i can rule that out.
thanks.
EDIT: should i use unrevoked, or unrevoked forever?
Whether you are rooted or not, makes no difference on any problems with the radios. You do not need to unroot to fix it.
What you need to do, it to flash a stock ROM, about the time that you purchased the phone, then flash the radios from that time period as well, then you can flash up to the current radio files and whatever ROM/Kernel you want to use.
There is a full list of Radio Files, Recoveries, Stock ROMs, RUU files etc in the stickies of this forum.
Simple Search works well too.

Welcome to sprint. As stated above, there is nothing you can do about it, the network just sucks. I haven't gotten above 100kbps on 3g in over a year, and I live less than a block from a sprint tower.
thanks guys.. yea its a tower issue, i rolled back like suggested, flashed radios, etc etc.. same shyt signal. local tower is under maintenance.
