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.

Tried EG31, EK02, and EL13. Going back to EG30. Anyone else?

I only had a handful of ghost and 1 full LOS on my EG30 phone during the couple of months I've owned it. I installed EG31 and had no issues, either... I have tried the stock OTA update and a couple of EK02 ROMs with multiple LOS. I had 3 LOS today on an EL13 variation. I guess I just have a POS, but I can't shake LOS in any way. So...
I've gone back to bone stock EG30 with only root to get busybox and superuser. (so I can run a couple of apps). So far, no LOS.
Both at home and at work, I'm on the fringe... perhaps maybe the ET4G isn't the phone for me...

EK02 was good for me but I've had issues with LOS after I leave my Airave's range on EL13. My wife's phone on EL13 doesn't have any problems so I think I might need to reflash. EG30 was the worst for me on LOS so I won't go back.

I love EL13.... My phone didnt update to EK02. I tired to switch to it but not a go. My 3g on EL13 is crazy fast in DC.

Even though I have gotten a few LOS bone stock they were very few and very far between...I got identical performance out of any rom with the stock kernel.
If you are using any kernel other than the stock kernel that matches your modem....well...eliminate some variables before you condemn the phone.
However, if you have tried all of these versions with the stock kernel (and matching modem...I have had LOS explosions with mismatched stock kernel/modem combos) I would definitely consider that phone a dud.
FWIW EG31 (especially for the modem) is my favorite.

I've never had LOS on any of the modems but was looking for better 3g. My 3g data speeds are better on EL13 than EG30 or EK02. I never tried EG31. Wifi connection is much better on EL13, too. With the other modems it disconnected as soon as I went out the door onto my patio. EL13 stays connected 50 or 60 feet from my house. 4g is staying connected better as well. BTW, I'm on Calkulins ROM v2.0.1 with EK02 Kernel. I just flashed the EL13 modem on top of the EK02 Kernel after wiping data and cache with no issues so far.

I've tried a few variations, but tried to keep kernel/modems together -- i.e. EG30/EG30 using Chris 41Gs repacks. My phone didn't LOS for a very long time then all of a sudden it did. At that point I didn't fear root as I had avoided root to avoid LOS. But... after experiencing it stock, I've tried several things. LOS seems to be my trusty sidekick now whenever I'm in a weak signal area (which is much of my day).

Have ran EG30, EG31, EK02, and now EL13. The only time I ever had LOS was with EG30 running LoStkernal, and only happened once when I was in a very bad coverage area. That being said EG30 sucked for me when it came to data speeds. I had to use WiFi in my house for any data. Accuweather wouldn't even update most of the time without timing out. All the other modems have had data on par with my OG Evo, but EG30 sucked and I would never go back to it.

Haven't had los in probably over a month using el13 and rogue ek02 currently but probably not sense eg31

I ran stock (rooted with no custom recovery) EG30 until yesterday (so, 3 months) and had maybe five LOS. I never tried EG31, and EK02 failed (because of root). I always had great battery life with EG30, usually going 24 hours or more before I HAD to charge with normal usage. (Note: I don't define normal usage as streaming Netflix or Pandora for 8 hours a day!)
I flashed Cauklin's stock EL13 with the EL13 modem, and so far my battery life seems to be even better. If fully charged, I used to drain down to 94% overnight (12-6:30). With EL13, I only drained down to 96%.
WiFi does seem a bit stronger. Cellular reception doesn't appear to be any better based on indicated signal strength. 3G seems a little better, but its hard to tell since I don't constantly monitor the 3G signal strength, and its NOT tied to the antenna bars (I can have 1 bar of cellular reception, but get 1.5Mb 3G speeds in some areas in Milwaukee, or I can have 5 bars and get 100Kbits).

No more Los for me finnally I'm so haaappppy

EL13 here baby, no LOS ever since i updated to EK02 and then 13

I've had no Los since I started using the ek02 kernel with eg30

Currently running EL13 with Calkulin's rom v2.5. Absolutely no LOS, which previously was happening every hour or so. I am -extremely- pleased today!

I completely reset the phone to factory and flashed EL13 + Calk 2.5. No LOS today but I'll have to give it a few days to be sure....

EL13 all the way!

[Q] CM7 Modem- does it matter?

A liitle background:
I ran BonsaiRom with the EB13 modem for months.
Battery life was great. 3+ days with the "fat" battery.
I've tried 5 or 6 different roms since the sprint GB upgrade, the first of which preferred the EI22 modem so I "upgraded" to EI22.
Since flashing the EI22 modem, battery life is terrible. It may be due to the fact that I live in a low signal area. Battery stats confirm that most battery usage is for phone signal.
I'm now running CM7 and plan on sticking with it. (Is CM7 great or what?)
So my question is, will CM7 work with EB13 even though EI22 is recommended?
btw I've seen signatures in these forums that show people running CM7 with other modems. I'm sure I'll try it anyway but I'm just curious as to you guys experiences.

Yeah, I'm pretty sure the modem is independent of the ROM even in cm7. I'd try using the modem that works best for you in your area.

There has NEVER been a rom that needs a certain modem. Bonsai did, I dunno why though. It should've worked anyway.

Thanks for the info guys!
Over the next week I plan on cycling thru different modems to determine the effect on battery life.

[Q] Is there any difference between all the leaked modems?

I was wondering if there is actually any coding differences between any of the leaked modems. Are they just adding a modem into the leaks like there are final ota's? I've been installing modems as they come out and have not noticed any appreciable differences but that could be just where i live.

Most of them are the same but different build number.

Differences
Well I dont' know how much is CM9 getting better. But I seem to get differences in reception and battery life with different modems. Newest ones seem the best. You might just be getting incremental improvements that you don't notice, or service is already pretty good in your area so you don't notice the better reception in bad areas.

I was beginning to wonder if they were just different flavored sugar pills (placebo).

Definitely placebo.

better reception
I got a better reception and speed going from EL29 to FF18. i mean its not much. but went from -96dB to -91dB for my reception.

I'm on [UPDATE][KERNEL][ROM]tFF18 with FF18 repack with AGAT recovery 0.2.1 rom with ff18 modem and its a big improvement over other roms/modems I've tried.. Net speeds are up from around 1.5 mbs d/l to almost 3 mbs and I get 3-4 bars on the phone signal instead of 1 maybe 2.. And I'm in the mountains of Tn.

I know how you feel. In NH and VT, they don't believe in cell towers. Alone with the mts too reception can be really horrible, but with FF18 modem it has improved.

Best modem for JB roms??

just tried fi03 and my 3g speeds were higher than 4g

It's whatever modem works for you
I know some popular ones are FH13
FI25..FF18
I personally use F125..And works great for me.. Also make sure to upgrade your prl /profile on a tw ics rom or GB rom

Imma noob but I've been testing and...
So far with jelly bean I've noticed the modems change your speed a little but the best way to get speeds is tweak your wimax hidden menu. Doubled my speeds on FI03 (best for my area) I do recommend u try ff18. Seems to work best with most ppl. Wasn't my case but it wasn't horrible.
Sent from my E4GT running paranoid android 2.16

I've gotten the best signal with FH13 so far. I tried out FF18 and I was able to get a 4G signal where I wasn't able to with FH13. Even though I was able to connect to 4G in these areas, I still got better speeds in the same area with 3G on FH13. Try flashing different modems and do some speed tests to figure out which modem works best for you!

fi25 works great for me. low ping and high uploads :good:
