Uh...data works bud, and I'm on EG31.
[Samsung Epic 4G Touch] sportsplayer5959:
Ok. They recently released the EK02 ROM and Modem. If you say you are on the EG31 modem then you do not have the EK02 modem... just the ROM. Im just trying to say that if you are on EG31 or EG12 Modem you will not be able to flash the EK02 modem. Sucks because i am on EG31:(
[Samsung Epic 4G Touch] sfhub:
He's not saying the EK02 ROM won't work with EG31.

He's saying the EK02 *modem* update won't allow you to go from EG31 to EK02 *modem*.
[Samsung Epic 4G Touch] agentfazexx:
Oh, okay. Damn I need more caffeine.
[Samsung Epic 4G Touch] sportsplayer5959:
Haha i feel ya.
[Samsung Epic 4G Touch] Just_s:
Why would you attribute that to the modem when there are hundreds of users on the same modem without that issue?

What I can guarantee you is that you have a much greater chance of issues on the EG12 modem. If I were you, I'd start by running all of the known data fixes and running different kernels before flashing another modem.

I foresee those of us who jumped on the EG31 modem too quickly regretting our decision down the road. Hopefully we are not stuck here, even though it is working great for me atm.
[Samsung Epic 4G Touch] agentfazexx:
EG31 was somehow given to me. Let's hope Sprint didn't eff me up.
[Samsung Epic 4G Touch] sportsplayer5959:
Did you just recently get your phone and it came with the EK02 ROM (android 2.3.6)? If so that is very strange that they gave you the EG31 modem with the EK02 rom. I would have assumed they would give you both the EK02 ROM and modem
[Samsung Epic 4G Touch] agentfazexx:
Got mine in September or early October, had 2.3.4.
[Samsung Epic 4G Touch] sportsplayer5959:
Oh. Well that sucks you have EG31. Im stuck on the same boat. I hope they can pull the EG30 modem soon so we can flash the EK02 modem
[Samsung Epic 4G Touch] agentfazexx:
EG31 is working fine AFAIK.
[Samsung Epic 4G Touch] sportsplayer5959:
Same for me. But from what i hear EK02 fixes LoS so we will be able to flash any kernel and not get LoS.
[Samsung Epic 4G Touch] agentfazexx:
Ahh okay. Well I guess we have to wait for these amazing dev's on here to get us a workaround. :)
[Samsung Epic 4G Touch] mattykinsx:
Obviously the EK02 release isn't the final release and therefore people with EG12/EG31 won't be screwed.

I'm sure that the devs on here will find a work around for it before the final release anyway.
[Samsung Epic 4G Touch] freecharlesmanson:
solution if you are on eg12/31

well some may call it unethical, dont know about you guys but im pretty frosted about the los issue and most of all never getting any acknowledgement from sprint concerning it. so im going to claim the phone is having bad los issues again and return it. the new phone will be on eg30 ^_^
[Samsung Epic 4G Touch] agentfazexx:
Uh...they've acknowledged it several times, and said they're releasing a fix for it in December.
[Samsung Epic 4G Touch] Ghost117:
So I just got my phone, and have the EG30 modem. LOS is somewhat of a problem but my biggest issue right now is that I am roaming from home and work, which is a bit ridiculous. Should I flash EK02 and see if it helps? Will this do anything to screw over my warranty if say I want to return the phone and go back to T-mo within my 14 day grace period.
[Samsung Epic 4G Touch] 1lazysheep:
i'm still getting ghost LoS with the EG31 kernel. :(
[Samsung Epic 4G Touch] expertzero1:
yeah, you said eg31, that doesnt fix los bug.... :confused: i wish there was a facepalm smiley
[Samsung Epic 4G Touch] dkotoric:
I just updated to Ek02 and my data speeds have drastically decreased, I just updated so maybe it will improve.
[Samsung Epic 4G Touch] 1lazysheep:
i flashed it before EK02 was available. no one knew if it would fix LoS or not. some people said they experienced less, some people experienced no change. i was in the latter group.
[Samsung Epic 4G Touch] hermeticist:
I get more LoS's with eg31 when using overclock kernels. None (since Sunday) using Rogue stock on Blazer ROM.
[Samsung Epic 4G Touch] MWaV:
I've been reading these threads and trying to get a better understanding of how to tell what modem do I have.. I recently soft bricked mines and if serves me correct when my phone was stuck at the bout up screen I used EG30 stock tar to fix this issue. I'm on 2.3.4 with cwm installed. Flashed bubbys stock over to get rid of the exclamation mark. Please advise.
[Samsung Epic 4G Touch] qbking77:
Settings, about phone, and the last 4 digits of your baseband version is your modem.
[Samsung Epic 4G Touch] graffix31:
Just looking to see how people have been making out with this update. still on eg30 and was in a poor signal situation last night and it was terrible. thinking about making the jump up but wanted to see if it is actually helping people. i dont have any issues with los normally on a stock kernel but this seems like a worth while update, plus i would like to use a non stock kernel and not have los.

thanks
[Samsung Epic 4G Touch] EeZeEpEe:
Also using EG31 with Rogue stock and haven't had Los too.
[Samsung Epic 4G Touch] Ghost117:
Wanted to share my experience:

I just got the phone 2 days ago, and was having problems with crappy reception at work, which led to a lot of LoS problems. Last night I flashed EK02 and 1) reception is somewhat better and 2) no more LoS!!

Honestly, I was about the drop Sprint and go to Verizon or something, but this has fixed all of my problems (well mostly).
[Samsung Epic 4G Touch] dirtyharrywk:
I still get LoS with EG31. I my return this phone.
[Samsung Epic 4G Touch] sportsplayer5959:
Didnt mean to thank lol. No big deal. But i wouldnt return the phone. EK02 may fix los issues. Also, I am running EG31 with no los. The key is to run a stock kernel. Plus... this phone is a beast!!! Good luck
[Samsung Epic 4G Touch] crypt0kiddie:
Well... I started by flashing just the EK02 Modem as I was still on complete stock EG30.

In my basement, I never had bars on this phone. I always has no bars, but barely got single and sometimes would drop to ROAMING.

I've never had any LOS issues like you guys have, I've has LOS in the sense that I simply had NO signal because I was in my basement and just really couldn't get one.

Anyway flashed EK02, now I have two to three bars in the same spot downstairs where I normally have none.
[Samsung Epic 4G Touch] sportsplayer5959:
Good for you. Samsung may have gotten something right on this one
[Samsung Epic 4G Touch] YoungAceAtlanta:
So lets say i don't like EK02 modem.. can i downgrade back to EG30 ? i just got my epic touch and already have the LOS and signal issues in places where i get about 4 bars or so
[Samsung Epic 4G Touch] sfhub:
No, you can only downgrade your modem to EG12 and EG31. There is no standalone EG30 modem file for you to downgrade to. Currently, once you are off EG30, that's it for EG30, you have to choose one of the other options. Since the EK02 modem patch is made to work only with EG30, once you are off EG30 or off EK02, that is it for EK02 also. You can't go back (currently).
[Samsung Epic 4G Touch] YoungAceAtlanta:
Oh wow that sucks.. But thanks i understand it a lot better now
[Samsung Epic 4G Touch] ssconceptz:
EK02 works the best.
[Samsung Epic 4G Touch] graffix31:
+1 been running the modem since last night and caulks 2.0 using the ek02 build and it is running great. 6 hours on battery with minimal use in not he best coverage area and only down 7% on the battery. cant beat that.
[Samsung Epic 4G Touch] rdcrds:
Since you have never been on the other how do you know which is best?

I am on 31 i would like to try 30 again with EK02 but as stated i can't go back but i just want to know how you determined which was best since you never left the 30 build?
[Samsung Epic 4G Touch] 22350:
Does this mean that when the official ek02 comes out, everyone without eg30 will be stuck?

I wonder if there is any benefit to upgrading the other ek02 components without the radio.
[Samsung Epic 4G Touch] EeZeEpEe:
I was thinking the exact same thing.
[Samsung Epic 4G Touch] daneurysm:
Me too. Even though I completely see the logic fault...and I am having fantastic results with EG31...I can't help but think "awww, ****, could it be better??".

The grass is always greener on the other side....when you can't try any and determine that for yourself, lol.

wifi working now after updating profile and prl
[Samsung Epic 4G Touch] pcmedics911:
I just put on EG31 via qbking77's instructions for going back to stock then rooting.

I put on the kernal loskernal+ as well. I got the LOS first time ever (I had EG30 in the past).

I"m going to go back to the stock pull and test this with EG31 modem. If that fixes the LOS then I guess i'm stuck w/o root for a bit.

Report later today.
[Samsung Epic 4G Touch] xlGmanlx:
Negative, you can still root with automatic root
[Samsung Epic 4G Touch] berto55:
My 3g and wifi speeds have been pretty slow! Will flashing EK02 improve that??
[Samsung Epic 4G Touch] Just_s:
I would say, not likely, but doing a hands free update probably would take care of you.

[Samsung Epic 4G Touch] pcmedics911:
Ok.. as for LOS with EG31 and Rooted ROMS:

I had LOS 1X and data was quite slow in weak area. Had another sprint phone that had low signal for data but the EP2 had 0 data signal.

I have EG31 w/LostKernal+ and put underneath the remove yellow icon kernal then installed via zip the lost kernel.

I went back to stock today (using qbking77's October 2011 links for the stock rom) and the EP2 has NOT had a LOS and actually runs quite smooth.

As smooth as it is..I would prefer to be rooted!

just got to find a smooth + stable + no LOS rooted rom or waiting for a cooked EG31 rom that is supposed to be released by sprint this month.
[Samsung Epic 4G Touch] sambo989:
If you are on EG31 no way to downgrade back to EG30?

So pretty much if you are on EG31, the only option is to ODIN to EP2?

I wasted about 3 hours yesterday looking for a way to get to EG30 somehow. EG31 for me gives me about 3 LOS a day...

I am using Calkulin's E4GT v2.0

my wife's phone had EG30, so she went to EK02 no problem... its just mine.

if anyone has a flowchart to make sense of the modems and where your baseband is currently and what your options are, I would really appreciate it.

Thanks.
[Samsung Epic 4G Touch] Just_s:
You don't need a flow chart, it's pretty simple and clear cut.

For modems (radio):

If on EG30, which came with the phone you can go to EG12, EG31 or EK02; but cannot go back to EG30 from any of them.

You can go from EG31 to EG12 and vice versa, but cannot go to EK02 from either.

You can go from EK02 to EG12 to EG31, but then cannot go back to EK02.

You can stay on EG30 and have the freedom to choose what to move to when better documented info is available or wait for official releases.

For kernels:

Version compatibility is interchangeable and effect on LoS appears to be significant.

For ROMs:

Version compatibility is interchangeable and effect on LoS appears to be zero to minimal.

I have found through my own experiences, watching the forums and reading a lot, that modem barely has an effect on LoS if at all. ROM does not effect LoS at all for me. If you want to mitigate LoS, you need to find a kernel that works for you. And LoS will effect every E4GT, rooted or not, but to varying degrees and with varying frequency. Chances are at some point every E4GT user is going to experience LoS even if they haven't yet.

Calk's 1.5a+Rogue 1.1 stock gave me LoS only a couple of times in over two weeks. My current setup has been 100% LoS free for almost a week since Calk's 2.0 was released.

The key for me seems to be the Rogue stock kernels.

My wife still gets LoS daily on her completely stock, unrooted E4GT.

My previous best setup was Calk's 2.0 (EK02 ROM) + Rogue 1.1 (EG30 kernel) + EG31 radio. So you can see that versions between components are entirely interchangeable.

Good luck and try not to get too caught up in the "modem madness" that seems to be going on.

There is already a method to switch modems without issues. We just don't have the source modem.bin for EG30.
[Samsung Epic 4G Touch] kaiyen:
So I, too, went to EG31 before fully understanding that I could not try EK02. I accept that as my "fate" for not having read as far out into the discussion as I would have liked. My bad.

I didn't haver any LoS since I upgraded on Friday. The whole weekend I was good. But this morning...lost it. Argh.

We'll see how it goes.

[Samsung Epic 4G Touch] japper88:
I am tempted to go to EK02 but haven't had any LoS problems with EG30, so maybe I'll wait. Only time I ever experienced any LoS was when I was on some early custom kernel's back in October.

Is there really any benefit with EK02 if I don't have LoS issues?
[Samsung Epic 4G Touch] Just_s:
What kernel/ROM combo?

Personally, I would wait until an official version of a modem us released. Who knows what will come with the next release.
[Samsung Epic 4G Touch] syncron:
There are a couple things I don't understand regarding radio fws. First, why is there no EG30 modem dump even though plenty of people are running it?

Secondly, where are the different modem fws from? Were they released by Samsung or the chipset manufacturer, or are they mods written by the community?
[Samsung Epic 4G Touch] sfhub:
Currently haven't found a way to dump the modem from a phone, so if we don't get a full modem.bin from Samsung/Sprint via ODIN tar file or OTA update, we don't have that modem version.

The easy way to think of it is the modem is currently write-only.

They come from Samsung either officially or unofficially and either directly or via Sprint.
[Samsung Epic 4G Touch] Russ T. Nail:
Not sure if this is where i should post this, but this morning I just flashed to EK02 and went from average 3G speeds to atrocious speeds in the same location. Oddly enough 4G speeds remain the same.

on 3G in the past I was around D:1.3 Mbps U:0.4 mbps

Now on 3G I just recorded D:0.05 Mbps U:0.43; second try D:0.18 U:0.48

Those 3G speeds are literally unusable which is why i tested it. I didn't realize at first because my WIFI seems to also work at similar speeds. Anyone else notice a massive drop in 3G speeds?

Other info: I updated both the profile and prl. I recorded these speeds or similar on both calkulin's 2.0 and starburst 1.9.8 (old nandroid that I wanted to try because of different kernel). I also tried this on Strong Steve's most current release. I didn't actually record speeds, but did notice that downloading apps on 3G was impossible. I feel like this must be modem related. Any thoughts?
[Samsung Epic 4G Touch] sfhub:
Either there are more factors than just the modem or it isn't related to the modem. Otherwise more people would be seeing the change you are describing.

Sprint in my area can vary day to day quite a bit.

Also they are doing NV related work in various areas which could result in network issues.

If you can find a different Sprint phone, let's say at the Sprint store, that has much faster speeds than you are seeing, side-by-side, then that would point to something specific to your phone.
[Samsung Epic 4G Touch] Russ T. Nail:
Any ideas on what I should try to figure this out?
[Samsung Epic 4G Touch] sfhub:
Go to the Sprint store and test your phone side-by-side with some other phones.
[Samsung Epic 4G Touch] sambo989:
Thanks!

I think from all the surfing around and looking at youtube videos about our phone, your post was the most clear.

I am on Eg31, funny thing is we activated 4 lines all with epic touch 4g,

everyone else has EG30 and has upgraded to EK02

I am not sure what my baseband was before i flashed calkulin 1.5

but when I upgraded to calkulin 2.0, i could not flash the ek02 modem from within clockwork.

I did not experience LOS however, but I am not sure which step i took to fix it, because I did so many things the other day.

I will stick with EG31,

and your advice that it's more about the kernel is probably accurate.

Thanks again.

maybe they can sticky your post.
[Samsung Epic 4G Touch] Icebluemale30:
Is it really worth all the trouble?

I'm a real noob when it comes to the SGS2E4GT so I did the upgrade to EG31 at the time that was the only way I saw to root with Odin but now there I see different ways to get to EK02 so i went ahead and ordered another one fresh with EG30 on it so i can upgrade to EK02 but my question is "Is it really worth all the trouble?" :confused: :confused: :confused:
[Samsung Epic 4G Touch] sportsplayer5959:
Not really. EG31 works fine. Plus EG31 users should be able to flash ek02 soon so its no big deal
[Samsung Epic 4G Touch] 22350:
So you don't think that being on eg31 is going to bork our ability to go to ek02?
[Samsung Epic 4G Touch] sportsplayer5959:
I doubt it. Like many of the developers have said, samsung usually releases the modem tar file when the official release has come out. So when all non-root users get the update, we should get the modem
[Samsung Epic 4G Touch] Just_s:
Wasnt sure if you were replying to me on this, but either way, glad you got it figured out. There are waaaaaaay too many people stressing out over what radio they have. AFAICT, EG12 is really the only lemon among the bunch. Running any of the other three is fine. It's really all about the kernel at this point.

Hopefully with an official release of a build directed at correcting the known flaws, we can all get back on the same page and enjoy this beast. For now, EG31 is great for me so no complaints here. :)
[Samsung Epic 4G Touch] Just_s:
For information purposes only

Hopefully this will move us all in the right direction and get things on an even playing field.

Official EK02 being released

I don't have this or know where to get it. Simply relaying the info that it looks like it is in the pipe and some users are probably already receiving a push. As far as I know accepting this update will break root and may or may not be immediately rootable afterward. The idea is to wait until one of the devs gets an updated build out.

[Samsung Epic 4G Touch] bjonesy77:
for those of you trying to upgrade to EK02 from EG31 but having trouble, visit this link and download the file. I've spent the last few hours trying to revert to EG30 from EG31 and have been unsuccessful. I've tried using all other recovery images and been unable to get EG30, they all flashed EG31. I even received the Sprint OTA update but was unable to install it because I was on EG31. I found this .tar on the acs forums, flashed it, and was able to get the eg30 modem back.

Once I had the eg30 modem back, I was able to upgrade to ek02. It will revert you to the stock eg30 modem, then you can use any of the other .zips through clockwork mod to bring your et4g up to ek02 and hopefully eliminate the LOS problem.

I'd have created my own thread with this link, but I didn't make it, so I will let the creator bring it over to XDA if he so wishes.
