Flash a rom that is 2.3.6 that stopped it for me.

[Samsung Epic 4G Touch] Thank Me Later:
I went back to the EK02 modem. It's faster for me in my area. The EL13 recovered from LOS quick through out the day though. If I got it, it would be gone in a second or two.
[Samsung Epic 4G Touch] Biker1:
I am also getting the same error message using CWM.

I am currently on EG30 trying to flash EL13.

Before I try flashing with ODIN, I'm trying to see why I can't flash with CWM.

I tried twice, after downloading EL13 two different times, in case I had a bad dl or flash.

Third times a charm??

UPDATE:

I could not install the EL13 Modem with the EG30 Kernel I had installed.

I flashed the EL13 Kernel, and then Flashed the EL13 Modem without issue.

The above may help others trying to install the EL13 Modem while they have the EG30 Kernel installed. I don't know if the above is apllicable to others, as it was to me regarding the conflict.

sfhub was a big help to me ;)

The EL13 modem is just horrible for me, I got full bars and places where I get 3mb and up I now only getting 300kb or 600 , 4g speeds are great tho, ima just go back to EK02

[Samsung Epic 4G Touch] Thank Me Later:
This is why I went back to EK02 modem. EL13 gave me better signal as far as bars being more consistent but my data speeds took a major hit on that modem. They were super duper slow. Right now I'm running on EK02 modem 2.3.4 :)

E4GT Modem EL13 is horrible for me so i was gonna go back to EK02 but i get that message above. My question is do i need to go back to EG 30 or 31 to get back to EK20? or should i try changing kernal. on Caulk 2.5, with EL13 kernal, thanks in advance

nvm, fixed the error, just reflashed eg30 and rebooted then reflashed ek02

I installed the EL13 modem and my 3G speeds on average, increased significantly compared to the EG30 modem. I never installed the EK02 modem.

EL13 is horrible here in metro Atlanta....odined back to EG30 then flashed EK02 in CWM all is working better.....4g was slower than 3g with the EL13.

Yea, I'm in North Jersey as well, spend a lot of time in NYC, and speeds with EL13 have been unbelievably bad.
[Samsung Epic 4G Touch] I2izzo:
Ok so I'm kind of lost here... I had EG30 and updated the modem to EK02... I see everyone talking about EL31... what exactly does that do? Fastest internet speeds? And is it benefit much by doing it? Sorry I just have no clue what these modem updates are doing and can't really find a straight answer.. thank you in advance!
[Samsung Epic 4G Touch] YoungAceAtlanta:
EL13 some users claim to have better speeds and more bars in places where they only get two or none ... I have horrible everything with EL13.. it all depends where you live tho.. try it out, test your speeds, if you don't like it flash EK02 again.
[Samsung Epic 4G Touch] I2izzo:
OK so I ran some speed tests... EK02 pulled an avg of .7 MB and EL13 pulled an avg of .033 MB.. lol to flash back to EK02 can I just flash it right over the el13 or do I have to flash to eg30 then ek02?

When I flash the modem, it gets to like 98% and then just sits there.. never finishes. What am I doing wrong.. lol thanks guys
[Samsung Epic 4G Touch] sfhub:
Which modem and how are you flashing?

If you are flashing a FULL modem (not a PATCH upgrade), then keep in mind only the latest kernels like EK02 and EL13 support flashing FULL modems.

If you try to CWM flash a FULL modem on an older kernel like EG30/EG31, it will hang for a while then eventually timeout. If you have done this, wait 2 minutes after the flash started and then press and hold the power button. It'll either reboot or reboot into recovery. From there you can go to android and you'll be at your previous modem version (ie the upgrade didn't take).
[Samsung Epic 4G Touch] evolart:
Thank you for that post I was wondering why I couldn't complete a flash of EL13. Will have to upgrade to new kernel.
[Samsung Epic 4G Touch] Just_s:
The problem with posts like these is that there is not nearly enough information. Posting what modem you have is the equivalent of telling your doctor "it hurts." The modem is only a small part of the overall system. If you don't have a signature or aren't stating what (ROM + Version + Base) + (Kernel + Version + Base) + (Modem Radio Base) then no one will really be able to help you improve anything. If you look at my signature, you can see the setup I am running. For me it has been flawless. I have run it for a week and my phone has never run smoother, cleaner or faster and the stability is wicked!

Yesterday, I had to flash back to absolute stock. I Odin-ed the EG30 stock tar and used my $2 jig to go as stock as humanly possible so that I could take my phone back to Sprint. (They needed to fix a major issue with the way Google Voice gummed up my calls after a mobile number change.) Anyway, I decided to run completely stock for the day. This a.m. I re-rooted via auto root then restored my nandroid (setup below) and the difference was incredibly palpable. Truly night and day. My phone with an all EL13 setup is so, so much better than stock. I had a good run on an all EK02 setup as well, but this setup with zero CIQ, zero LoS and much improved signal is very hard to beat.

For those of you who are having speed issues, you should check your overall setup. I don't think it is mandatory to have kernel, ROM and modem versions match (I've run many times with hodge-podge setups), but in this case it seems a matched set works much better. Also if you have not rebooted multiple times since flashing a new modem and have not done a hands free reset since flashing a new modem, I would bet heavily that the issue lies there.
[Samsung Epic 4G Touch] PCap79:
Sorry if this is a dumb question...but I'm new to the Epic 4G touch...coming from an evo this is all very different. Once I am rooted and flash a custom ROM, can I flash any of these modems? Or will certain modems only work with certain roms?

The reason I as is that I'm about to flash the newest version of UnNamed. In case the included modem gives me trouble I want to know if I can just flash one of these other modems over UnNamed without any problems.

Thanks guys!
[Samsung Epic 4G Touch] qbking77:
Any modem works with any rom :)
[Samsung Epic 4G Touch] Thank Me Later:
I think the new modems EK02 and EL13 might be capped speed. They're not consistent for me. Sometimes it's ok, sometimes super slow. Stock my 3G was consistently good. Not fast but it was fast enough for 3G. 4G speeds fell off with new modems too. It doesn't matter what rom I'm running. The new modems give me better signal and strength but my data speeds fell off.
[Samsung Epic 4G Touch] sc00basteve:
If you haven't done it, I suggest letting the modem settle for at least 24hrs.

It could be a placebo but it REALLY seemed like the EL13 modem had horrible speeds at first and then the next day, and the following couple days, it was much much better.

The final suggestion is to reflash your ROM of choice again AFTER you have updated the radio.

So far... No LoS & good speeds on EL13 and Calkulin'sE4GT ROM.

I'll test this out when I flash EL13 again. I'm running EK02 modem right now.
[Samsung Epic 4G Touch] Biker1:
Just to let you know, I'm running the EL13 modem, and my 3G and 4G Speeds have improved. With 3G, I'm getting around 1Mbps download (B4 I was getting around 300Kbps,and with 4G, I'm getting 5-10Mbps download speeds (B4, 4G was inconsistent, if I could get it at all, and the speeds were about half.)

The above is not scientific of course, But I have noticed a very nice improvement.

I don't know if the improvement is because of the modem, the Sprint upgrade they are in the process of doing regarding the towers, data speed, etc., or all of the above.

I know that they are in the process of making Improvements to their Network across the Country.
[Samsung Epic 4G Touch] jklong03:
Sorry if I am late to this game, I was very actively following the "cannot flash out of EG31 to another modem" discussions, but have been away for awhile.

Anyway, saw this thread and decided to take a chance on flashing the .zip version of EL13 to my surprise it took with no problems!

So I guess my question is, when did someone crack the "EG31 and your stuck there" issue??
[Samsung Epic 4G Touch] Thank Me Later:
That's awesome bro! I wished I could say the same. Signal strength improved on new modems but my data speeds seem slower for some reason. They have their moments of being quick I guess.

I believe you can flash the EL13 modem over any modem you're on. There is a video showing how to go back to EG30 from EG31. You can do it non-rooted too because I've tried it on stock EG31. Follow "QBKING77" on youtube. He does quiet a few on the Epic 4G Touch.
[Samsung Epic 4G Touch] sc00basteve:
The prerequisite is that you have a kernel that allows for full modem flashing instead of modem updates.

Currently they are EK02 & EL13.

Quote from Calkulin's E4GT ROM thread:

Modem

- Zip's must be flashed through a CWM based recovery & Tar's must be flashed through the PHONE option in Odin

If you have 3G\4G connection issues, be sure to update Profile after updating by going into Settings\About phone\System updates

[Samsung Epic 4G Touch] jklong03:
Thanks for clarifying that for me. As I said, I successfully flashed the latest modem over my EG31 and the kernel I was running was an EL13, so solves the mystery for me.

Again, thanks (button hit) for the clarification.
[Samsung Epic 4G Touch] lafester:
nah the kernel has NOTHING to do with the modem.

what fixed it was we got full .tar files for eg30 and el13 so now you can flash those modems from any state. We may even have the full ek02 now but I haven't been keeping up lately.
[Samsung Epic 4G Touch] sfhub:
Actually the EG30 and EG31 kernels can only flash "patch" modem updates. They can't flash full modem updates. I discovered this when testing different upgrade scenarios with the EK02 modem.

If you flash the same modem through ODIN it will work fine, but if you flash through CWM, it uses the kernel to do the final flash.

Flashing full modems on EG30/EG31 kernels will just hang for a long time, then time out.
[Samsung Epic 4G Touch] lafester:
Ahhh I don't use cwm to flash modems.
[Samsung Epic 4G Touch] frkkeene@gmail.com:
Eg12 > eg30

I have and SGS2 which I bricked and had repaired. I now have the EG12 modem. Since I am having issues with the phone waking up for calls, can I go back to EG30?
[Samsung Epic 4G Touch] sfhub:
Yes, all the links you need are in my signature. 2nd post of the ODIN threads has the modem as an individual ODIN flash. The CWM ones directly download the zip file to flash in CWM. If you want the full release, use the first post in the ODIN threads.

UPDATE:

Kernel version EL13.

Odin flashed modem EL26 on top of EK02 finding new modem performance not so great.

Signal wasn't as strong dropping a bar every so often.

Tunein Radio app performance was terrible data speeds much slower not constant speed test confirmed

I flashed back to EK02 using (update-modem-EK02-FULL-CWM) all is well again :)

I will install EL26 modem again tonight see how it goes ,If it fails to improve I will flash EL26 kernel with it and report findings.

UPDATE:

Reinstalled EL26 in CWM format , signal & speed performance is much improved = to EK02.

Maybe cwm clear cache before flash helped not sure.

I also installed EL26 kernel shortly after finding its pretty darn good thus far.

Device Wake up is much faster with smoother performance so if your loving UnNamed now you will love it even more with new kernel on board.

Flashed EL26 through ODIN.

Wifi is now dead.

Going back to EL13 then trying the CWM method.
[Samsung Epic 4G Touch] sfhub:
Which kernel are you running?

I flashed EL26 modem (via CWM but it shouldn't matter) on stock EK02 kernel and then tested both cell data and wifi data. Both worked as expected. The cell data was slow for the first run of speedtest, but then with all subsequent runs performed the same as previous EK02 modem.

[Samsung Epic 4G Touch] Shadeoblac:
Just flashed CWM zip over EL 13 modem running Calks 2.6 with rouge 1.3 4g jumped up in speed. 3g is pretty much the same. Signal bar keeps moving from 3 bars to no bars, 4g is doing the same. Haven't lost connection though. No LOS yet.
[Samsung Epic 4G Touch] Dchibro:
I ran 5 Speedtests on EL13, then flashed EL26 and ran 5 more. I saw a 18% average increase in speeds with EL26, but with typical speed variability. I'd say my general conclusion is they bring equal performance over time. i.e. no noticeable change.

Also, my wifi is working fine after flashing EL26.
[Samsung Epic 4G Touch] TurboFool:
To be clear, does this mean I can't flash this over the EL13 modem? I would need to roll back to EK02? Or is this just saying I need an EK02 or newer kernel?
[Samsung Epic 4G Touch] 3volution:
Nevermind.
[Samsung Epic 4G Touch] sleshepic:
Just flashed the cwm modem zip, def see a slight improvement in 3g speeds. I have TERRIBLE speeds at my work, even though there is great reception, so its a good testing area I think. Ran two tests before flash, and two after. They are the top four, see for yourself. Look at those blazing sprint 3g speeds!
[Samsung Epic 4G Touch] cidica:
Have to admit so far so good with the EL26 modem. actually had better service in a few places here in Mi and no LOS that I've seen atleast.
[Samsung Epic 4G Touch] sfhub:
You can flash over any modem.

The restriction is the CWM (or whatever recovery you use) was bundled with an EK02 or newer kernel.

When you flash modems using CWM/Recovery, it uses the kernel to do the final flash. The earlier kernels could only flash patch-style modems. If you flash a full modem with those kernels, it will hang for a long time, then time out.

If you use EK02+CWM/EL13+CWM/EL26+CWM to flash this, then everything will be fine, regardless of which modem you had initially.
[Samsung Epic 4G Touch] paranoid android85:
do i have to be on a stock rom? im on cm7 and i tried to do heimdall to flash the modem but it didnt work, i kept getting an error. i then tried to flash the zip thru cwm and ive been stuck on the updating modem to EL26 for a little over 5 minutes. should i do a battery pull? or just keep waiting? thanks
[Samsung Epic 4G Touch] sfhub:
Not sure about your heimdall error, but the description you gave with CWM is a symptom of having a CWM packed with an older kernel (EG30 or EG31). Those kernels are not able to flash a FULL modem update, only patch updates.

You can press-and-hold the power button until it reboots. It may reboot directly to android or into recovery. If into recovery, then press [Home] to reboot system now.

Then if you want to flash the EL26 modem through CWM, first install a CWM that is packed with EK02 or newer kernel.

2 subcontractors that work for me have modem EK02 on their ETs , side by side testing with EL26 has reveled major disappointment to say the least.

Speed test throughout the day Ive found EL26 to be 100 - 200kbps.... some times more below EK02.

I hope this isn't Samsungs final build because its far from improvement.

When it comes to EL26 kernel thats turned out to be a major disappointment running on EL13 base rom.

I've noticed some performance issues with EL26 but I think EL13 has had the best performance so far.

<slaps self> I didn't update my PRL or Profile when I flashed EL26. On EL13 my speed test were always between 300kbs and 450kbs download speed and uploads around 15kbs to 20kbs with 2 bars of 3g . I don't have 4g at home so I haven't tested it.

With EL26 my speeds at home were pretty much the same but I forgot to update the PRL and Profile, I did so, and now my speed test are between 750kbs and 950kbs download and uploads between 35kbs and 45kbs with 2 bars of 3g.

Updating the PRL and Profile improved my 3g speeds at home significantly on EL26.

My WiFi results are maxed out so that's good. We will see how it works everywhere else.

[Samsung Epic 4G Touch] raveniselizabeth:
I had to update my post....I was on a different Jersey tower than I normally use for some reason.

I am in Staten Island NY and the tower I usually use is about 20 km away. The funny thing is that there is a closer tower that is only 11km away and it gives me speeds that are slower. I thought the closer ones would be faster. Maybe the 20km tower got an update? Interesting. Tower updates make me happy!!! SpeedTest isn't the MOST accurate test anyway though LOL.

I test my wifi because one of the how many modems sucked as far as catching my wifi signal.
