LOS has more to do with the kernel

Hi

I am on eg31

my wife is ok EK02. she has never gotten los once

i had been getting LOS with eg31, but then I changed kernels and I have been LOS free now for 2 days.

I would try different kernels.

its not the modem.

Sam
[Samsung Epic 4G Touch] playya:
I would suggest updating everything... the modem is done now update your kernel and rom base to 2.3.6 and run tests before getting so frustrated
[Samsung Epic 4G Touch] clayginn:
Just downgraded to EG30 and then upgraded to EK02 with Zero issues.

Thanks you all

Will let you know with the LOS as I average 1-3 per day
[Samsung Epic 4G Touch] berto55:
The ek02 modem on this thread is based on the one that was released by sprint not to long ago???
[Samsung Epic 4G Touch] arivis:
I upgraded from EG30 to EK02 modem and now I have no GPS capabilities. Can anyone help me figure it out please?

Thanks in advance
[Samsung Epic 4G Touch] Just_s:
You do realize that qbking created both this thread and the one in your post? Same OP, same files.

Not sure why everyone is having so much trouble. I downloaded the EG30 zip from my phone via Opera (from id10terror's thread, same as 2nd mirror in OP), booted into recovery (Rogue 1.1.1), flashed the zip without wiping anything and around 30 seconds later I was back on EG30 modem from EG31.

Easy as pie. No need to go to other threads or do any rituals. Download zip from OP right here, flash and go.

Still no LoS issues on EG30 because I didn't change kernels. It's all about the kernel for me.
[Samsung Epic 4G Touch] berto55:
How do you switch recoveries??
[Samsung Epic 4G Touch] Just_s:
Rogue 1.1.1 does, 1.1.0 does not. Just update to the Rogue EK02 stock kernel and you are good to go. Link in my signature.
[Samsung Epic 4G Touch] berto55:
Is this ek02 modem the updated version from sprint??
[Samsung Epic 4G Touch] qbking77:
Yes it is.
[Samsung Epic 4G Touch] Just_s:
I guess it is. I'm staying on EG30 until I see a good reason to switch. May even go back to EG31 since it was great for me and now I won't be stuck there :)
[Samsung Epic 4G Touch] berto55:
I'm getting a lot of roaming.
[Samsung Epic 4G Touch] xlGmanlx:
did you update your profile and PRL after flashing new modem?
[Samsung Epic 4G Touch] Just_s:
As gman says, update everything. I recommend hands free reset, how-to link in my signature if you need direction.
[Samsung Epic 4G Touch] berto55:
I haven't flashed ek02 yet...will though
[Samsung Epic 4G Touch] Beejis:
Is the EK02 modem zip file only suppose to be 169KB?
[Samsung Epic 4G Touch] sfhub:
Yes, it is a "patch" of EG30. That means it only has the "differences" between EG30 and EK02 modem.bin's. If you don't currently have EG30 modem.bin, it won't work.
[Samsung Epic 4G Touch] clayginn:
Had a LOS today with EK02 but I have the MOD that fixed itself. Updating my profile now and will try that. Will pull the logs tomorrow and post in that thread but I am worried that the update to boosted power a little to the radio. I just have a feeling that this is issue is a Hardware issue that they are trying to fix with software. Maybe wrong but it is just a feeling.
[Samsung Epic 4G Touch] rbaucom:
We had issues such as los of service with our Samsung moment. They claimed they fixed it, the fix was when los occurred with 15 minutes it would reset the phone radio and wifi, till if reset you had no phone service, no calls no text nothing...

of course a long reboot fixed it.

The developers over at sdx forums finally got rid of it with custom kernels and ROMs. And made me going from the is a POS to wow this is a nice little phone.

The stock fix NEVER fixed it.

BUT that being said this seems to be sprints (without counting the iphone) current darling....
[Samsung Epic 4G Touch] 1lazysheep:
i didn't update my profile and PRL after flashing EK02 modem. followed Just_s's How To on how to do hands free activation. let's see if this improves things...

update: right after i did the hands free activation, i got the 2.3.6 update notification. updating now. will report back...
[Samsung Epic 4G Touch] Kikoshi:
Sorry wrong thread :/
[Samsung Epic 4G Touch] Duce HD2:
After flashing to EK02 I got 2 Los on the same day. Back to EG31 then.
[Samsung Epic 4G Touch] kaiyen:
Okay. editing my response. I went up to the EK02 Rogue Kernel. PRL and Profile. Then one-click Odin flash to EG30. Then went to EK02. That was about 30 seconds ago.

Let's hope this works.

[Samsung Epic 4G Touch] japper88:
I upgraded to the EK02 modem from the EG30 modem, no real difference for me (bad or good).
[Samsung Epic 4G Touch] gtg465x:
edit: Houston, we have a problem.
[Samsung Epic 4G Touch] agentfazexx:
Make your own thread so people can find it easily.
[Samsung Epic 4G Touch] kaiyen:
I think there already is one...that's how I got back to EG30>EK02 so quickly. I did have to update the Rogue kernel but now I'm on EK02. I did one step Odin to get back to EG30, I think...I forget which was which. But bottom line is I got back out of that loop easily. Very awesome.
[Samsung Epic 4G Touch] todivefor:
How did you do this? I thought the whole modem issue was there was no full modem, but only a delta going from EG30, as a result this thread:

http://xdaforums.com/showthread.php?t=1368419

Just trying to learn something.
[Samsung Epic 4G Touch] agentfazexx:
So I am on the 2.3.6 ROM that is on this forum, and EG31. I have an issue frequently where texts won't send, but I have service. Does this fix that?
[Samsung Epic 4G Touch] gtg465x:
I just flashed the delta in the first post on top of EG30 to get to EK02 and then dumped the modem partition to get the full EK02 modem. dd if=/dev/block/mmcblk0p8 of=/sdcard/modem.bin bs=4096
[Samsung Epic 4G Touch] sfhub:
Did you reflash what you dumped? From past experience that modem partition is unused. That is how the famous EG12 came about. If you zero it out, your phone still boots fine and works with data.

Not sure why, but when previously dumped, that partition yielded a 16mb file, but yours ended up being 5mb. The modems shipping from Sprint are around 15mb.
[Samsung Epic 4G Touch] gtg465x:
Hmm, that method works fine on the other Galaxy S II variants. I will flash back to an old modem and try it. Also, it is a 16MB file. The zip is 5MB because it's compressed. Will report back soon after testing.
[Samsung Epic 4G Touch] sfhub:
Sorry you are right about the size, I thought I had unpacked it. I think the issue is CDMA phones aren't actively using that partition. Maybe that partition is specific to GSM phones?
[Samsung Epic 4G Touch] japper88:
I've gone from EG30 to EK02 with no noticeable difference in performance where I live/work.

But it did seem to regain signal faster when I went from no signal areas back to signal areas. However, it still took a long time for it to find signal if I came out of the subway, about as long as EG30.
[Samsung Epic 4G Touch] gtg465x:
Odd. Mmcblk0p8 just contains the EG12 modem like you said. So where the heck are they keeping the actual modem?
[Samsung Epic 4G Touch] sfhub:
During the modem upgrade, the kernel uses some gpio ports to write directly to hardware from memory.
[Samsung Epic 4G Touch] gtg465x:
Ah, crap. Well don't mind me then. This is the first CDMA Samsung phone I've used so I'm still getting used to the wackyness.

Just odin it to my phone..... I was unable to upgrade to EK02 so I tried EL13. Working good as of right now. I will update later with more info.... Thanks for the modem leak
[Samsung Epic 4G Touch] rdcrds:
320 meg zip? what are we suppose to do with it just flash it? would be nice to explain what we do with it since it is 320 meg rather then just post it :) but thanks for the post.
[Samsung Epic 4G Touch] agentfazexx:
So what's EL13 all about? I'm on EK02 now. Should I flash that? Not seeing much info on this.
[Samsung Epic 4G Touch] ogeretla:
That's what I am saying. NO INFO. Serveral people seem to be taking the plunge, guess i will wait on results or something... It seems to be a full modem instead of a patch, which sounds promsing but. There isn't 100% confimation of anything.
[Samsung Epic 4G Touch] agentfazexx:
Yeah, I know. EK02 is working fine so far, so I'll wait until info is in the OP.
[Samsung Epic 4G Touch] sfhub:
It isn't an OTA update so therefore they wouldn't have made it a patch.

It is an ODIN tar file which includes

1) bootloader

2) secondary bootloader

3) EL13 Sprint Pre-load

4) EL13 Modem

5) EL13 Kernel/Recovery

6) EL13 ROM

It does NOT include data, so it will NOT erase your Android user data.

Initial reports are that CIQ was removed by Samsung and the Soundpool bug might be fixed.
[Samsung Epic 4G Touch] agentfazexx:
Any differences between the EK02 (http://xdaforums.com/showthread.php?t=1367971) and EL13 ROM's? Refer to the link for the EK02 ROM I'm talking about.
[Samsung Epic 4G Touch] blackte4:
I just update my modem only.....
[Samsung Epic 4G Touch] sfhub:
I would suggest asking that question on the EL13 thread.
[Samsung Epic 4G Touch] ogeretla:
Thanks. So when you so it's not a OTA... Does that mean they are not distributing it or what?
[Samsung Epic 4G Touch] sfhub:
OTA updates are meant to be distributed over-the-air, so they usually (but not always) ship them as "patches" to the current version because they can drop the file size 5-10x. This reduces download time and download resources, but requires your system be exactly what they expect.

This particular release is a "leak" of today's build. It is for flashing in ODIN.

It wasn't actually released by Sprint/Samsung for general consumption, but probably is an internal build which they will test for a few weeks, and if there aren't any problems will release as an OTA patch update.
[Samsung Epic 4G Touch] ogeretla:
OK. Thank you very much for a detailed breakdown. I am fairly new to all of this android hacking but have a strong overall technical background. So I appreciate details of software. Thanks.

[Samsung Epic 4G Touch] cyclonebee:
I'm having a bit of a problem. I was on EG31 and flashed the EG30 modem in odin to get to EK02. The process to downgrade to EG30 went perfect, now I tried to flash the EK02 modem.bin and I got to where it says to wait for 2 minutes. I waited 20 minutes and nothing changed. I pulled the battery and tried again, same thing. Now I can't get into the phone, CWM or anything. What is the next step I should be taking to get a working phone back?
[Samsung Epic 4G Touch] sfhub:
Can you get into ODIN download mode?

Power down phone, wait for all lights (including capacitative button lights) to go out

Press and Hold [Power][VolDn] until confirmation screen shows up

If you can get into that mode, you can flash the EG30 factory restore and your phone should be responsive again.
[Samsung Epic 4G Touch] cyclonebee:
Thanks for the help, currently downloading it :)

Will this allow me to get the OTA or what would get me to rooted EK02 after I get restored?
[Samsung Epic 4G Touch] qbking77:
Should be getting info up for everyone soon enough... going to try and make vids tonight
[Samsung Epic 4G Touch] sfhub:
Skip to the summary in this post (or read it if you like). You don't need to do step #1, just continue from step #2

e12) I told it to install the EK02 update, but something went wrong, now it won't prompt me again, how do I install EK02?
[Samsung Epic 4G Touch] grandmastem:
I'm assuming the EL is flashable with CWM, and to not use odin? Also, how come the EK02 CWM zip is like 160K, but calk's EL is almost 5 and a half megs. What is the huge difference? -Grand
[Samsung Epic 4G Touch] sfhub:
EK02 modem flash is a patch update. You need to have EG30 installed to flash it.

EL13 is a full modem update and can be installed over any existing modem.
[Samsung Epic 4G Touch] cyclonebee:
Still having problems. I went back to stock through this thread: http://xdaforums.com/showthread.php?t=1383678

That put me on EG31 baseband, so I odin'd the EG30.bin to put it back to EG30, then put the official sprint EK02 on my external sd card, and went through stock recovery to update and when it starts it shows me a progress bar for a few seconds and then disappears and all it shows is the exclamation next to the android. It stays hung up there, tried twice. So now I'm still sitting on EG30.

Thanks for your help thus far. I am so confused when it comes to this EG31>EG30>EK02 process for some reason, never had a problem rooting any of the other 3 android phones I've had in the past.
[Samsung Epic 4G Touch] sfhub:
Are you sure that put you on EG31 baseband? It should have put you on EG30 baseband.

The OTA update is supposed to take a while. It may even seem like it is hung. How long did you wait?

At the exclamation point press the [menu] button on the phone to see if there is any error.
[Samsung Epic 4G Touch] cyclonebee:
Yeah, I'm sure, it definitely went back to EG31. I'm getting error 7, which is weird since I didn't touch anything and flashed complete stock. I never knew about hitting the menu key for errors, very cool.

---------- Post added at 01:03 AM ---------- Previous post was at 12:49 AM ----------

Going to try flashing EG30 again and see what happens. > Confirmed, it flashes me back to EG31 baseband, what the heck? And it's still giving me Error 7.
[Samsung Epic 4G Touch] sfhub:
You are absolutely sure you downloaded from this thread and are using the self-extractor?

[ODIN][STOCK][TAR] SPH-D710.EG30_CL435734 (EG30 Modem/Kernel/ROM - Factory Restore)

Just in case I made some mistake, I re-downloaded the self-extractor file and installed over my phone. It came with EG30 baseband, just like it has for others who installed it.

Are you sure you didn't use the other ODIN thread which is also labelled EG30 but is actually EG31?

I simply don't see how the same ODIN file could give me the EG30 modem but give you the EG31 modem.
[Samsung Epic 4G Touch] cyclonebee:
That might have been what I did, man. I actually just finished flashing to EK02 finally. I used the Odin One-click here instead: http://xdaforums.com/showthread.php?t=1383927

Exact same results for me. Makes me wonder if the phone stops trying in order to save battery. When I'm on the train and lose signal for a long period of time in a tunnel, it's about 1 minute before I get a signal back. I know my work Blackberry will kill it's battery trying to find a signal.

I put the EL13 modem on my EK02 setup. My 4g and Wifi are the same but my signal bars are pinned to full now! On all previous modems I would see them going up and down even though I was in the same spot. I really hope this continues because I think I found my perfect setup....*knock on wood...
[Samsung Epic 4G Touch] N00dle:
Mine send fine either way. Since my initial Los with a custom kernel after I got my phone I have been sticking to stock re packed kernels.

No real problems whatsoever
[Samsung Epic 4G Touch] cephraim:
Can I install the EL13 modem after doing just Option A of the auto-root? Or, should I install some other custom recovery that has a nandroid backup option first. If I *should* install another recovery, should I just run Option C in the auto-root tool, them the EL13 modem upgrade after that?

Thanks,

[Samsung Epic 4G Touch] qbking77:
It is similar, yes. A backup as in a nandroid backup? Nandroid backups do not backup the modem. If you flash a bad modem, just redownload or flash a different modem (usually doesn't happen).

Modem's can only be upgraded through flashable zip files through clockworkmod if there is an OTA update. That would be the only way it would even have a possibility of being flashed with a rom (most likely will not be with roms... usually have to be done separately).
[Samsung Epic 4G Touch] gpgorbosjr:
I've never flashed a modem on an Android phone before....

[Samsung Epic 4G Touch] qbking77:
Not a dumb question at all.

Modems affect the radios of the phone.(see op for what it affects)

It can improve those radios. It might also make them worse... Each phone handles them differently.
[Samsung Epic 4G Touch] Beejis:
This new radio doesn't make you lose calls due to deep sleep does it? EG12 did that to me and I had to return the phone. With LOS and missed calls due to deep sleep it was too much. Because of that modem I'm now hesitant to flash any new modems unless I can flash back.
[Samsung Epic 4G Touch] sleshepic:
I would love if someone could comment on whether data speeds are affected at all, I get terrible speeds in most zip codes now, half what buddies next to me get on other sprint phones. But I don't want to get my hopes up to much :)
[Samsung Epic 4G Touch] Beejis:
I asked this in Calks thread but since this will probably be the main modem thread I'll ask again here.

Same deal here. On EG31 Wifi was about 3500 KB/s (local network) and on EL13 max 350 KB/s. 3G seems like it might have been just a tad faster with slightly less latency. Maybe 110 KB/s average. (I live beside a tower...)

I've seen this before on my EVO with modems....very strange. As long as I don't LOS I suppose it doesn't matter. From my experiences though, LOS has been remedied by applying the stock kernel. (For me...using Caulkin ROMS)

Has anyone found any benefit other than possible LOS being fixed and minor speed improvements?
[Samsung Epic 4G Touch] hermeticist:
The only way to determine which is faster is to have two phones with different radios speed testing at the same time.

Sprint speeds differ minute to minute.
