Added Poll! Central discussion of ek02. Let's see if it solves LOS

Hello everybody. I updated from eg30 (I only had the phone for a day and had one LOS on eg30) and went to ek02. I wanted to create this thread for all the brave souls who updated to let everyone know if it's worth losing the eg30. I haven't been running it too long... only ~ten hours or so. I haven't had LOS yet. As far as reception, speeds, quality, etc. I have no idea; I just got the phone yesterday night.
Let's try and keep this organized. If you want to report your findings on ek02 please do so in this format:
Previous LOS ~frequency (and Modem version):
With ek02, LOS frequency(if any... hopefully, none):
data speeds/ reception on old modem:
data speeds/ reception on ek02:
Just a courtesy thread for those who are laying back and waiting.
Edit: a few people brought up a good point. Kernel matters! Include kernel observations too.

Would love to see some reports. For those on eg30 that are going to update to ek02 run some speed tests first then update and run more and compare them. Thanks.

Pretty much my thoughts. Hopefully people will actually post their results in this thread to help others who haven't updated

With the EG31 modem and EG31 [or EK02] stock kernel, I have not have one LOS or ghost LOS.
Been 12 days.

I never got them while I was on the EG30 or 31 stock kernel. I would get los at least once a day on every custom kernel.
Today I got los (on the EK02 modem and Lostkernel) but it seemed to happen when the signal was handed off from my airave to the normal mobile signal. Once I left airave coverage I was looking at my phone. I saw it disconnect from it, my bars came back (full) but no 3g icon or data until I rebooted. I just flashed the stock Ek02 kernel so hopefully I wont get it again like I didnt on the other two stock pulled kernels

I'm referring to just the modem:, not the kernel.

Considering that they are both contributing factors (although the modem is more so) they are both relevant

Same here and I went to some known bad spots too and the EK02 kernel with EG31 modem seems to be working really well so far. The kernel does play a role so hopefully we will see some comparisons using same kernel

Yeah Kernel plays a big part f,sure.
LOST kernel los has been out of control , many of its users went back stock kernel finding los to be little to none.
Why thats ignored placing majority of blame on modem is beyond me.

I knew that...(not really ) I'll add kernel to the op. Thanks

I'm running both the EK02 kernel with the EK02 modem. Not one LoS to speak of yet (running since about 1pm yesterday). The bars don't jump around as much, I seem to be getting a better signal. Before this I was running the Rogue stock kernel and had the EG30 modem (of course).
As far as speeds, that's difficult to say given all the variables on a mobile connection. So far though the 3G download speeds seem to be higher, double what they were almost. That doesn't say much when they were 7 - 24kBps before. Now I'm looking at 30 - 50+kBps. Like I said, that could just be a fluke so more testing will need to be done. WiMax has about the same speeds too, was 380kBps average, now it's around 440kBps. - Those are kiloBYTES not kiloBITS for those that get confused.
The kernel seems to be a significant improvement though. Benchmarking scores went up on Antutu, Quadrant, and Linpak. The system had no lag before so without benchmarking you really can't tell.
Lastly, the ROM updates are nice I guess. A few icon changes and the overscroll glow has now been changed to blue, as opposed to the yellow it was before. Other than that nothing fancy or notable has changed from what I can tell.
One addition here, the battery life is very noticeable with the update. For me at least - it drains significantly slower than the previous stock kernel.

I havent had LoS or ghost LoS ever since I installed the modem and the kernel, I usually get 3 a day but 18 hours in, nothing, nada.
I have noticed the phone "snappier" than normal though

Was anybody getting random hot reboots with any eg31 kernels? If you have, did the ek02 kernel remedy that? Others and myself have been trying to solve our hot reboot issue (in Calkulin's thread). We don't know what is causing them for a select few of us.

I flashed the ek02 kernel on blazer rom and still get hot reboots. I've tried almost every rom with different kernel combos and still get them. Got them on stock eg30 and eg31 kernels and modems.

Can you either post here or pm me a list of apps you have? I had these reboots on my Evo 3d and I'm using the same apps. Let's compare the apps that we have... because as of right now, the only variable I haven't tried is a rogue app. :/

I don't think it's an app but maybe a custom script used by the rom developers. The only time I didn't get the reboot is by going back to the stock rom.

If it was a script.... wouldn't everyone be getting these issues? Some are getting it on every single rom too.
If you're on Calk's do you think it's the undervolt?

just updated mine a couple of hours ago, so this may be a bit premature, but I dont really see any increases in network speed. When using the speedtest app the before and after results were about the same. That being said I am at work, where I get a halfway decent signal if I m outside the building. The true test will be when I get home tonight. Aside from network speed being the same everything else seems pretty much unchanged, with the exception of the phone seeming to be a bit more snappy, although it could just be in my head. Lin pack scores did seem a bit higher, but nothing to go crazy over. I have only had one LOS since launch day, so that isnt really an issue.

I just wanted to chime in with my experience after flashing the EK02 modem. I flashed it about 3 hours ago, after I had received 2 LOS at work this morning.. and typically been getting at least 3-4 a day (stock pulled kernel with CMW - Lost kernel was no better)
So far I haven't received any LOS but I've been getting the best 3G speeds I've seen yet. I was getting around 15KBps average in my office (and that is after months of running speed tests!) and I just ran a few tests now and I'm getting ~70KBps after 3 runs. Very noticeable improvement although it isn't spectacular, much more acceptable. I just compared it to my previous speedtest.net result history and it's by far the best speeds I've gotten since I've owned the phone in this same exact location (my desk at work)
Thanks again to everyone involved getting us this leaked firmware!

I don't think so. I was on calks, flashed a stock kernel, took out the undervolt script and still got the reboots.
Again, I never got them on a stock rom, only custom ones.

ei22 slow data

Hey everyone. Im running ei22 and i have horribly slow data speeds on 3g. the latency is in the 1000s to 1500s and speed is around 100kbps or slow both down and up. please help. i dont care what rom, what modem, or what kernel i use. i just cant use this like this. my only request is to be on gingerbread and to be able to use 4g when its avail.
Thanks in advance.

Try CleanGB. Simple and stable. Good battery life. It was my first ROM and im happy with it.

All the GB ROMs have 4G working fine. Your 3G issues sounds like a bad tower near you. You can try reflashing the modem. If you go to a GB ROM you will need to Odin in the EC05 modem so you can flash the EC05toEI22 modem.

Have you tried using an older modem? I think every phone has a sifferent one that seems to work better than the others. Mine personally gives me the best spped with the EH17 modem. Flash a new one and see what happens.

I've felt that data is slow on EI22 since I installed it. You may be experiencing the same thing, it may be inherent.

Slower data on CM9/AOKP roms.. no HSPA+ 42 perhaps?

I noticed on all CM9/AOKP based roms on the T989, my 4G data isn't as fast. By comparison on stock and Darkside roms, My speed tests are consistently double-digit download (10-14 kbps) and around 3kbps upload. But on CM9/AOKP based roms, I don't get above 5 kbps down, and 2 kbps up. These are the typical speeds I would be getting on an HSPA+ 21 phone.
Do we have any information on why this is? Do CM9/AOKP not support HSPA+ 42? Is there a script I can run to improve this?
Thank you in advance.

I noticed the the same thing. On tw ics I normally get 8-18mbps. Aokp and cm9 5-8mbps but good enough
Sent from my SAMSUNG-SGH-T989 using xda premium

I have had sporadic success getting 13 mbps by flashing the le1 radio included with darkside. For the most part though i cant use cm9/aokp for this reason, no one really knows why to my understanding.

I flashed one of the Tellus radios and it's working very well for me. Running AOKP

I agree-I have the same issue. I'm on CM9 and love it but it's vever been as fast as the Dark Side roms.

lol but noooooooo everyone looooves CM roms because they don't have bugs, issues or anything

Try flashing one of the modems for the Darkside ROMs when you flash an AOKP or CM based rom?
That should do the trick. Probably is just a modem issue over anything else.

No it's not a modem issue. I've already tried all the Darkside modems and the issue is the same and consistent. I truly believe whatever makes HSPA+ 42 work on stock and darkside is not implemented on the CM9/AOKP roms, because the speeds I get are consistent with what people with Nexus phones in my area on T-Mobile get, and they only use HSPA+ 21.

I've gotten a best of 18.50Mbps down on AOKP.

Any particular radio/kernal combo?

just the 6/15 build, i didn't flash any other radio/kernel. now i'm on the 7/3 build and am getting about 10Mbps down inside my office building (which has pretty bad reception, the 18Mbps was inside a house).

Yea no joy with that, reg build without any radios fetches me 8 Mbps max in an area that i get 13 Mbps.

Yes, I noticed a slow down from GB to stock (debloated & rooted) ICS ROMs... But it seems like AOKP may be even a little slower than that.
I've seen some users post lines that you can replace in the build.prop file which they said gave them faster speeds on AOKP... but then people just stopped talking about them.
The user did say that the only way he could see a difference in speeds using the build.prop fix was to tether his phone to another device and do the speedtest on it... For some reason he was certain that speedtest.net was reporting lower numbers for AOKP ROMs, but the speed was still there... You'll have to go back and read the AOKP thread in the general section to find it.

I don't know about that I flashed UVLE1 radio from darkside and actually got speed test results of about 12 Mbps to 13 for a few hours. After about a half day of use it dropped back down to 8. Reflashed the radio and it still wouldn't go back up.

I've tried several speed tests, not just speedtest.net and I get the same consistent results of slower data speeds. As far as real-world results, I have seen problems streaming video on PLEX on 4G with CM9/AOKP roms that work just fine with Darkside. So it's not just an issue with speedtest. Something is different. Would love to have some input on this from Eugene or Yaldak or someone like that.

ASOP, AKOP, CM10 and wimax

I would like to have to have just a normal Jelly Bean 4.1 or know 4.2.1 experience of my phone. I tried out the Pacman rom and CM10 rom. Both have the same issue. My 4g wimax speeds go from 10megs to 750kbps.
Is there something that I missing or is everyone just fine with horrible speeds? I even tried the temp boot and updated my PRL and such.
Is there anyone running a stock android 4.1 or 4.2.1 with 10 meg wimax speeds? or does this not exists.
currently im running TW jelly bean FL16 rom....perfect wimax. so its not JB.
~also which I found annoying was this was the same issue on my piece of crap evo3d. wimax would go from 10megs down to 750kbps on every ASOP, AKOP, CM9 and up.

Some have said that its because there is no kernel source for JB. So aosp roms don't have kernel source for the kernels they use.

No. It is working.
Tbh I never fully trust speedtest.net servers. For example.. I have 2 servers in columbus, oh and 1 in radnor,oh near me. Columbus servers are 50 miles closer to me than radnor ones. Still I always get 2-3 times faster results on radnor servers.
So in reality I have a faster throughput but I am misled by server caps. Now i know this is not the case because obviously on a tw rom you get much faster results.
What I am trying to say here is that when I am on 4g on non tw roms, 4g is much faster than 3g even though speedtests tells another story for me. 4g and 3g speedtests give me similar results. I also get faster tranafer rates when downloading files when on 4g.
So my guess always has been that on non tw jb roms, speedtests are not measured correctly.

i live in downtown Cincinnati with perfect 4g signal. Speedtest is one way to check. Another is by trying to download things.it took a couple mins to download speedtest. I mean its like being on 56k modem or something. So no 4g is not working correctly. it might be working, but at 1/12 of the speed its suppose to.

The source for aosp kernel was made from ics kernel source which apparently has a buggy 4g problem... That's why custom kernels also have throttled 4g. Hopefully after jb source drops somebody will make another kernel with the new source...

It's an issue with source built kernels. Nobody really knows why it happens hut it is what it is. Repacked kernels are where it is if you want 4g speeds to not be absymal.

[Q] Same carrier, two different phones, difference reception

I have my Galaxy S3 and my coworker has an HTC Evo. Both of us have Sprint and yet his phone gets 3 bars of reception whereas mine only gets 1, 2 if I'm very, very lucky.
AFAIK, he's running stock, unrooted and I'm running rooted with latest LiquidSmooth 2.9 with the MD4 modem. No idea what modem he has.
What could be the reason why he's getting better reception? Better antenna build in the Evo?

Some of it has to do with the rom. Some aosp roms show a more accurate bar reading...which is why your's is fewer. I wouldn't really get to worked up over it. They both probably get similar reception and data speeds on 3g

I would suggest Updating PRL / Profile. Maybe even trying a different Modem. Not everyone gets great reception on MD4. You may have to experiment to see which works better for you.

If you want to properly know if your device is getting less of a signal you need to flash a TW rom, preferably one which is close to stock update prl and profile. Then check your signal and data speeds compared to your friends. AOSP roms remember are built from leaks, and ported from other devices. There is no true aosp source for the Sprint S3. So there's lots of patches and coding which goes into getting the cdma radios working.

We've actually done a Speedtest together and his had a higher data rate than mine. I've had different modem with the earlier builds of Liquid Smooth as well, but still low reception. I've also updated my PRL/Profile in the past in hopes that it'll help but sadly no.
I'll look into having a TouchWiz ROM versus this one. I just love how LiquidSmooth is, so hoping I can find a TW ROM that's just as fun.
EDIT: I don't even know how to find a TouchWiz ROM. I figured it would say "TW" along the subject line, the same way AOSP does, but alas I cannot find that. I have heard of Goodness, is that a TW ROM?

Most likely cause all the roms which do not say AOSP or CM or AOKP or something like that are TW roms. I would recommend MOAR or TPR The People's Rom.

OP,
Unless you're being very careful with your comparisons and using quantitative, and not qualitative, data like db, seeing more "signal bars" means nothing.
Sent from my buttered S3

You must also keep in mind, that even after you switch to a TW Rom. There is no guarantee that you will see better reception. IE more bars. There are quite a few variables involved. What you should concentrate on is making your device the best it can be for you. As CNexus stated. When comparing you have to compare Apples to Apples, and Oranges to Oranges.
