when you guys mean loss of service, does it display the 3G icon but you don't get any data? or no 3G icon at all?

I've not rooted since there is currently no method to unroot, and a few times today even though I showed the 3G icon I couldn't get any data, had to reboot.

edit: or maybe something else would've fixed it but rebooting seemed like an obvious solution.
[Samsung Epic 4G Touch] abstraction21:
If I have 4g and Wifi turned off then yes, my 3g displays but it still does not work.

[Samsung Epic 4G Touch] mlee0921:
this is what has worked for the last 36hrs and couting:

everytime data dropped, i just updated profile and prl EVERYTIME. no restarts. didnt do the ##786# reset.

and now data has been working. i usually had problems with data after switching to wifi and then back to data, but now 3g shows up everytime i turn off wifi.
[Samsung Epic 4G Touch] us3rm3:
man..I'm glad somebody is having the sme problem as me..I'm rooted and my phone 3g n data keeps shutting it self off..I missed couple of important calls..resetting gets it to work with voice mail and txt messages showing up. plus, my phone battery drains crazy. turning the phone screen off and leaving it on my desk for 7 hrs with 2 or 4 mins of used drains it down to 0%. Yes!!!! 4 freaking min..

Flash the stock kernel through Odin. Everything seems to be working great for me. It removed root though. Just wait for Zedomax or ACS to build a bomb-ass tar file. Stock kernel runs so good on here its insane.

Flash stock then buddy's CMW then root and then reflash stock and you'll have root, CMW, and an actually working stock rom.
[Samsung Epic 4G Touch] us3rm3:
Thanks! I will give that a try. Flashing it right now..
[Samsung Epic 4G Touch] Silent25r:
No problem. Here is a link to the thread where I got the info from. Worked great for me. Even my benchmarks are back to what they use to be.

[Samsung Epic 4G Touch] Dj21o:
Ok, I had Zedomax v1. I removed root using the stock kernel (flashing through Odin).

So, now that I am on root, can't I just flash the CWM through Odin, and THEN flash the root file?

Why do I need to flash the stock kernel twice when I already have it?

I've had this phone since day 1, completely stock, did update prl, profile. Haven't had a single signal drop. Either I got lucky, or it probably is the root method. Would love root, but I'm sticking it out until there is a better method. Too many people jumped the gun.
[Samsung Epic 4G Touch] HaiKaiDo:
Not in anyway thread jacking here but if some of you rooted users would startup an ADB log as SOON as your phone starts up (set the log to very verbose) and then do whatever it is you normally do and let the signal drop. and then lock and unlock the phone a few times. And if you wouldnt mind sending me some of those logs in PM(let me know your root method and current kernel). you can either send me a txt file or upload them to pastebin. Im just curious to have a look around to see if theres something thats going into deep sleep mode or something and isnt coming back out. Either way, Id find it interesting to have a poke around.
[Samsung Epic 4G Touch] daneurysm:
CWM is bundled with the kernel so if you flash the CWM then you won't have the stock kernel. When you flash the stock kernel you lose CWM (and get stock recovery).

Someone's gotta build the tar with CWM + stock kernel.

---------- Post added at 05:26 AM ---------- Previous post was at 05:23 AM ----------

I'm absolutely positive that is what's going on.

It seems to happen to me only if I have had my phone sleeping for a while in a low-signal area. I'm willing to bet it's a combo of going to deep sleep and the signal state either when put to sleep or when waking up...(roaming/low signal on sleep and/or wakeup).

It hasn't happened when I've been playing with my phone. It also didn't happen last night while *I* was sleeping, lol. But it did happen at work yesterday when only 5 minutes lapsed.

EDIT: all of those are relatively low signal situations. I have not gotten a LOS in a high signal area, that I know of.
[Samsung Epic 4G Touch] mawst95:
I had the signal just shut off once so far. I was listening to music at the time so the phone shouldn't have been sleeping, though the screen was off.

Just to clarify -- this wasn't poor signal, this was going from 2-4 bars to a circle with a line through it (no service) as if I put the phone in airplane mode.

Is there an app that will let me log my radio (on and signal strength). I'm curious if this is happening at more times than I'm aware. If this is happening once every 3-4 days, I can deal with it. If its happening a few times a day when I'm unaware, then the phone is going back.
[Samsung Epic 4G Touch] daneurysm:
Before I flashed root I waited to see how things went, which is very unlike me. But in the time I was unrooted I experienced the LOS a few times and didn't think anything of it--I figured it must just be a bug of some sort. It didn't happen enough to bother me. Toggling 'airplane mode' fixed it a few times, resetting fixed it all the other times.

I, personally, don't think root kernels have anything to do with this. But if it is just put the stock kernel back and have root anyway. For the time being this is the fastest phone on the planet--the same planet where an EVO4G is still more than fast enough for almost anything. There is no need to OC yet....or for a year...or two.
[Samsung Epic 4G Touch] davedave1234:
You must be lucky because I can’t even do a Google search then click 2 links before the data drops, completely stock phone with only angry birds and Pandora installed. Nothing else but stock phone and apps. I want to root but I can’t even get it to work stock and I don’t want to take any chances if I have to return this thing.
[Samsung Epic 4G Touch] Dj21o:
People are saying now it is when you drop at a certain level in your data connectivity. Which makes sense, because I was at a friends last night and I had 0-1 bars for two hours and rebooted twice. And they live in the same area as me. So it has to be that.

I am going to work soon, so I will let you guys know as soon as I get there. It is easily a different tower, and my service is so-so in the building. :p

EDIT: I am at work now, and my service has NOT dropped one single time since I have been here. I reverted back to stock kernel last night and not one problem. I just need root again for my tether and I am A-OK!!

[Samsung Epic 4G Touch] mawst95:
My signal strength was okay when it happened to me. I'm fully stocked. It happened again this morning. Disappointing!

I set up a Tasker profile to automatically toggle airplane mode if I lose service. Not sure it'll work or that I set up the parameters correctly, but maybe it'll work and can serve as a decent work around for now.
[Samsung Epic 4G Touch] skribbles505:
I posted on another topic somewhere that using zedo's system restore/boot loop fix then going through the hands free activation has completely gotten rid of my LOS issue. It now behaves just like my EVO did reconnecting on its own when switching from wifi/3g/4g back and forth. It seems to me its a software bug, but I will say that the signal strength is still lower on average than it was on my EVO in the same locations o perhaps a combo of hardware/software issues.
[Samsung Epic 4G Touch] daneurysm:
I only get the LOS once a day or so, and that was with the rooted kernel. I'm not rooted on stock kernel and it hasn't happened once since I put the stock kernel on, but, I got the LOS issue before I hacked anything too...so...dunno what that's worth.

...I'd really hate to do a hands-free-activation, cuz every time I do in my past 4 phones I have to call in because of awful data speeds to have them do a "refresh" which I have been told is just a profile reset and/or hands free activation...but I've tried doing it myself and it has never worked and it works every time I call in (or chat-in)
[Samsung Epic 4G Touch] Megatr0n.:
I'm in the same boat as those who are waiting for a more field tested root before trying it on my phone. I like being able to make calls and use data. :p
[Samsung Epic 4G Touch] nabbed:
I have used rooted kernels since I got the phone on Wednesday. No problems with the so called LOS.
[Samsung Epic 4G Touch] alero:
Completely stock. Updated PRL, suffered LOS and battery went from 49 to 21 percent in a minute. Weird.
[Samsung Epic 4G Touch] Megatr0n.:
You might not have issues, but too many people are reporting problems for me to root my phone without thinking twice.

Just to get some clarification, could you list which root version you're using? And does everything (wifi, swype, etc.) work perfectly normal?
[Samsung Epic 4G Touch] daneurysm:
I can't comment for nabbed, but I'm using a stock kernel with SU installed. You have to flash CWM and a root.zip or rooted kernel then just flash the stock kernel over that. poof. now SU is installed. stock rooted with original baseband intact.

I haven't had an LOS since I did that. I had a rooted kernel and I did get 2 LOS. However in the 5 or 6 days before I rooted I also got LOS 2 times...so, make of that what you will.

I don't think it's the rooted kernel's fault. It might not help the matter, but, I don't think it's the, ahem, root cause.
[Samsung Epic 4G Touch] Megatr0n.:
Thanks for the clarification. I have some more questions (please excuse the my being oblivious to some things as this is my first android phone since I've been using iOS for almost 3 years):

(1) where do I get the stock kernel? Is that something that'll be listed on the development board that I can download like a custom kernel, or will I have to get it off my phone using software like ODIN?

(2) I googled CWM and it says that you have to be rooted before you use it. Your example makes it seem like you have to have CWM installed before you root your phone. Which is correct?

Thanks :D

EDIT: I think I just found the method you were describing in the development page. Is [RECOVERY] Clockwork Recovery◄ - Credit bubby323 / ACS the method/version you used?
[Samsung Epic 4G Touch] tenaciousj:
This is what I did also, here is what happened with me.

Got my phone Tuesday and no LOS or anything the entire time. Friday afternoon I flash bubby's CWM and then flash root. Go to bed and wake up 6 hours later and I got the circle with line through it.

I didn't care for the LOS thing so I flashed the stock kernel to see if that would get rid of the problem. Doing this I noticed I was able to keep root while getting rid of the yellow triangle which was nice.

Its been about 18 hours and no LOS yet.

I know some are throwing around the idea of low signal causing the LOS. I have no real input on the situation but I got an Airave so unless the signal on that dropped on that and that is what allowed my phone to have the LOS but I'm not sure. Airave was working when I woke up and noticed the LOS.
[Samsung Epic 4G Touch] paniro187:
has anyone got failed sms send and receiving?? once rebooted it clears up and sends and receives what wasn't sent and received before the reboot.
[Samsung Epic 4G Touch] daneurysm:
Yes, all of this is available in the development section.

1.) Flash bubby's CWM via odin--READ ALL WARNINGS AND INSTRUCTIONS OF HOW TO USE ODIN VERY CAREFULLY. This circumvents the need to be rooted to flash CWM while booted up to Android as you don't have to worry about OS permissions.

2.) Flash either a root.zip or a rooted kernel via CWM. I went with Zedomax v4(?) cuz I wanted to play with overclocking. I think the Kernel that was in CWM was pre-rooted anyway and just needed the SU binaries...but that may have changed.

3.) Flash the stock kernel via odin.

All done. Stock kernel with SU installed. That'll even erase the ugly yellow triangle and put back the stock splash screen.

I'm from a long line of HTC devices so this is all pretty wild compared to how we did things over there...but it's pretty straight forward so far. Just be sure to pay attention to ODIN and to pick the PDA check box for these things and load the files into PDA and to NOT have a checkbox for writing partition...that's not why we are in there.

...also you should probably make or buy a USB jig. If you do semi-hard brick that's your last chance. They look super simple to make but are even easier to order. Then you can also reset your 'custom binaries flashed' counter, just in case.
[Samsung Epic 4G Touch] davedave1234:
I never lose signal just data. I have never dropped below 3 bars but I just hang. For example, I search google then click a link and it loads the page. I tjen click a second link and it just loads 1/2 way the locks and wont do anything until I reset the link. But as I said it shows the same signal.
[Samsung Epic 4G Touch] silversx80:
I had LoS the first day I had the phone, bone stock. I also had lost 3G and WiFi capabilities at some point. Reboot always helped. Lost data and voice with signal showing as well while stock. Never lost 4G ability.

Just rooted today, experimenting.
[Samsung Epic 4G Touch] Dj21o:
Someone didn't correctly do it for you at Sprint, or you have a defective. I ran stock for a few days with no issues. Flashed v1 of Zedomax kernel, LOS every 4 hours.

Flashed stock tar kernel, not one problem for two days now. It was obviously the kernel messing with my phone.

It needs to stabilize before anything. Stock has great battery life nonetheless. :)

[Samsung Epic 4G Touch] DarkPhoenix:
We need to get a poll started so we can get a better idea of how many people are having this problem and whether they are rooted/unrooted what root method was used and what kernel is being used.

Edit: I have not had the LOS issue yet and I am unrooted.
[Samsung Epic 4G Touch] geekaren:
I've experienced loss of signal/service when running Zedo's kernels, but haven't experienced it now that I've flashed the stock kernel. Not drawing any conclusions there.... it could just be coincidence.

Not sure if it's material to LOS issue, but I read a post in one of the xda ET4G forums stating that the stock kernel has a different baseband version than some of the custom kernels. It was posted by someone who'd had to swap their phone out at Sprint. Of course, now that I try to find the post again, I can't... :rolleyes:

That baseband post made me wonder if baseband version variations could be a possible contributing factor to LOS.

---------- Post added at 10:52 AM ---------- Previous post was at 10:47 AM ----------

Good idea. Might provide good input for Sprint's analysis.
[Samsung Epic 4G Touch] silversx80:
There isn't enough data points to make that determination as of yet.
[Samsung Epic 4G Touch] Megatr0n.:
I've been stock since I received the phone on the 21st and haven't had any issues.
[Samsung Epic 4G Touch] Dj21o:
I'm not sure how I can stress that the kernel has an issue. We need to build off of stock, not off of international lol.

Sent from my Galaxy S II
[Samsung Epic 4G Touch] silversx80:
I'm not disagreeing with the fact that build off a stock kernel will yield better results. I'm saying that the kernel may not be the variable in LoS. We aren't sure as of yet, and more information is needed to determine the actual cause.

I've been running almost 17 hrs, no reboot, almost zero bloat (all Sprint, Samsung, SNS and DRM related apks off, minus TW) and I've yet to see LoS. I saw LoS within the first few hours I had the phone.

If I do see LoS, I'll flash a rooted stock kernel and gather more information.
[Samsung Epic 4G Touch] jamescho72:
7 days zedo root=los at least 1x a day. 2 days stock based root=0 los. I also believe stock los is bs. nothing else to say

I got my first LOS today. Circle with a line thru it and had to reboot. Ive been the strongest component for blamjng the kernels and hnfortunately im completely stock on the new phonr. Never rooted it or did anything. Just did the msl update so ill see if it comes back.

But yes LOS happens on stock also

its a hardware problem

has nothing to so with being rooted

i just got off the phone with sprint and they told me that samsung pushed an update on friday to fix a delay in receiving text messages which has borked the internal antenna. that would explain why i only started having problems yesterday.... sprint will give you a ticket number and they will fix your phone for free at a store.

call up and get it fixed.

its only going to get worse!

I have stock (never rooted) and I had the LOS at least twice (that I know of). Maybe root exacerbates the issue, but it is NOT a root only issue.
[Samsung Epic 4G Touch] will900:
That could be it. I never got los till after I rooted my phone that's when I was getting los once or twice a day, now I'm back on stock to see if I get it but so far I haven't

I got los from just cwm odin flash... I applied su.. Put back stock kernel and still have root and no los.. Otherwise constant los with zedo or cwm
[Samsung Epic 4G Touch] anubis13:
After 4 days of being on Zedomax v3 with NO problems I got a pseudo LOS where I still have bars but no 3g and the top status bar goes all green. Reboot fixed it. I flashed the stock kernel and I will see what happens.

Update: got LOS right in the middle of a call with a full stock kernel, non rooted.

Switching back to zedomax v3 so I can at least overclock.
[Samsung Epic 4G Touch] Silent25r:
I didn't have any more loss of services after returning to stock but my phone was still locking up on me. Sprint exchanged it for me and my new device hasn't giving me any of those problems yet.

The lock ups might have been related to me getting a defective device. I had rooted it but I didn't install any of my backup apps or make any changes at all to the OS so I could easily rule those out of the equation.

Ok I've been at work for 3 hours now with no problems. I guess there is something wrong with the kernel. Blah. I guess no cwm for a while.
[Samsung Epic 4G Touch] silversx80:
Got somewhat of a forced LoS yesterday. In stock Task Manager, cleared the memory. On the stock kernel, that action would sometimes reboot the radio. I'd get the circle with line for a few seconds, then bars + 3G would come back. Tried it for the first time on v3 of zedo's kernel and radio did not come back, had WiFi though. Reboot fixed it. Tried it again this morning and radio came back right away.

Ran for about 18hrs before that happened, no LoS. Been going for about 18hrs since and no LoS. Still on zedo's kernel.
[Samsung Epic 4G Touch] Megatr0n.:
I just flashed zedomax's rooted kernel and then immediately flashed back to the stock eg30.

I have super user access now, but will I be able to use wireless tether? Does the stock kernel support iptables?

Thanks

EDIT: No, I won't. Installed the app and it told me that my kernel didn't have all the features necessary.

EDIT2: Ok, it doesn't seem like my phone is rooted even though SU is installed... I tried installing droid wall and the app keeps saying that it doesn't have SU permissions and to make sure that I'm rooted.

I flashed zedo's pre-rooted kernel, and then immediately re-flashed the stock eg30 kernel. That's all I needed to do to keep root while having the stock kernel, right? If that's the case am I using the SU app incorrectly? It doesn't let me add any app in the SU program.

EDIT3: It appears that flashing the original kernel unroots the phone. I wish it also removed the SU app to avoid confusing noobs like me.
[Samsung Epic 4G Touch] graffixnyc:
I just wanted to chime in here and give my experience. The day I got my phone I didn't install one of the rooted kernels, I flashed CWM and then rooted the system with the zip file. I would get LOS at least 3,4 or 5 times a day. I then read all the debates about if rooting/custom kernels cause this. So for ****s and giggles I flashed the stock kernel posted in the dev section which also removes CWM. The phone was still rooted since I didn't use a rooted kernel but instead the root zip I flashed in cwm. anyway, since I went back to stock(without cwm) I have only had 1 LOS since and that was the first day I flashed it back. It hasn't happened since. I know there is a huge debate if rooted kernels and/or cwm caused los or not. I can only speak from my experience which is just one case out of countless. Removing cwm and staying stock (but still rooted) has fixed MY LOS issue. Cant say it will for anyone else and don't know what to say to the people who get LOS without ever flashing anything to their phone. I can only speak from my experience

i got my e4gt on 9/26. immediately dropped zedo's v3 kernel and cwm. i had nonstop issues with LOS. i flashed back to the stock kernel and still had the issue. after talking to sprint custrep, i exchanged my e4gt for another new e4gt on 9/28.

since then, i've left the phone running the stock kernel/recovery and i am unrooted.

i've installed about 20-30 apps and i haven't experienced any LOS thus far. only been two days but still much better than initially.

i've only had one problem thus far, one particular instance, the phone screen would not turn on. i would press the power button and nothing. i was just chatting on googletalk and the screen auto turned off like normal, but would not come out of that, so i had to reboot the phone. :(
[Samsung Epic 4G Touch] sfhub:
Sometimes there can be a bug in the stock ROM, that doesn't happen that frequently, which gets exacerbated by some other action. Sometimes these are timing related race conditions so changing how things work slightly increases the frequency of the bug showing up.

So in that type of situation both people can be right. It does happen in the stock ROM and it does happen more often when the stock ROM is changed in some way. Going back to stock might reduce the frequency, but the only true fix is to fix the original bug.

Not saying that is definitely what is happening here, just offering one possibility.
[Samsung Epic 4G Touch] Dalmus:
It seems to me that its more likely to happen when the radio changes state through either a reset or roam status. I can a cause the radio to lock up 3 times out of ten by toggling Roam Control.

Call it a coincidence but a have never had "los" and i have been rooted since day one root was out, i say coincidence because I always have my roaming set to "sprint only" for all phones, may we be on to something?
