Attached is a patch against the E4GT open source release (SPH-D710_Opensource.zip) containing defconfig changes necessary to get a source-built kernel that's as close to stock EG30 as possible. Also attached is a source-built test kernel that attempts to be indistinguishable from EG30 (hopefully same LoS behavior, unrooted, etc.). I've posted this before, but now that it's been tested (at least by daneurysm, thanks!) I figured it was worth making a dev thread so it would have better visibility to the folks most interested in it.
The purpose of this patch is to enable folks to build kernels nearly-identical to EG30, so as to serve as a proper starting point for custom kernel development (admittedly, a good deal of which has already happened). Since it's just kernel config changes, I welcome kernel developers to compare this against your own configs and make any changes you feel appropriate.
Background:
Compiling a kernel from the E4GT kernel sources with the shipped defconfig yields kernel builds that differ quite significantly from EG30. Among the differences, many folks have reported undesirable effects, such as exacerbation of loss-of-signal and other problems. There already exists efforts (e.g., LoStKernel) aimed at eliminating problems like loss-of-signal, but it's a common frustration among developers that what Samsung released as "EG30" sources appear bizarre, if nothing else.
A few weeks ago I posted an inconclusive initial analysis of the source situation, and followed up more recently with an attempt to eliminate all the defconfig changes in the source release in order to either get a kernel as close to stock as possible, if not prove that the kernel source release is bungled.
At this point, I'm uncetain if the source release is actually EG30 or not, aside from that the kernel configuration is definitely not EG30's (which this patch attempts to correct), and there may be some additional modifications to the Westbridge driver. As for the kernel config changes, unmodified source-based kernels include a good deal of debugging options (performance events, profiling support, tracepoints, debugging for preemption, mutexes, spinlocks, etc.) that touch enough of core kernel behavior to plausibly account for the problems folks observe in source-based kernels.
I know chris41g has indepenently implemented a fair number of these kernel config changes already, perhaps exactly those that exacerbate loss-of-signal. Still, for anyone interested in development that wants to "start with EG30 and go from there", this patch may well be of use.

LoStKernel Exp has these changes, thanks mkasick
big ups man, i hope this gets more attention so that more dev's feel comfortable developing aftermarket kernels.
"Sorry, you are limited to 5 thanks a day"
2 days in, running perfectly and so far no LOS at all, which is on par with the stock kernel.
Excellent work, thanks for the effort.

Update: 3 Days running, no LOS and nothing strange happening. Phone is running great. Battery performance is as good as stock, LOS occurance appears as good as stock (like I said, 3 days in and I've seen exactly zero). No strange foreclosures or fruit loops. No funny business at all. On any previous kernel I definitely would have had multiple LOS events by now.
I think you cooked up a winner.
Glad to hear. Thanks for testing it.

No problem at all.
Here is my final update: 7 days in. A+++, would flash again. Not a single LOS in the past week which is right on par with stock in pretty much every way. I'm sure it would go further, but, I've really got an itch to do some flashin'. I'm glad to have helped, but, it's time to move on, lol.
Thanks again. I see no reason why, based on my own experience, this wouldn't become a standard base.

That may explain the excellent experience I've had with 1.0.0.8 then. Well done guys. Big thanks to you both.
Okay. I finally got off my lazy (and recently very busy) ass and flashed LoSTKernel. While system performance was great (honestly, this phone runs so good stock that I can't tell a difference between stock and heavily tweaked and OC'd) I did notice that my signal bars and signal strength were better on your kernel than LoSTkernel v1.0.2.2
I had sworn that over the past week+ that my signal was looking stronger than usual wherever I went...but I digress....
I checked in all of the random corners of my apartment notable for their terrible (or decent, at best) reception. On the LoSTKernel I couldn't get anything higher than -96db...and that was standing with the phone pressed against the window in the 'hot spot' where with your kernel I got as high as -86db or better. In the "medium" spots where I can typically get -91db to -96db I was getting -101db to -106db on LoSTKernel.
On Starburst with the AOSP 4-bar meter this is a difference of as much as 2 bars with your kernel and zero bars (a difference of as much as 15db) with LoSTKernel in the same exact location.
I didn't have time to verify a difference with speed tests--and they would not be very trust worthy given the nature of radio communications and Sprint's spotty network performance in this area...I did load up facebook and the XDA app a couple times and I'll be damned if your kernel didn't seem noticeably snappier....but once again, anecdotal measures like that are nearly useless.
I'm not necessarily suggesting that your kernel is in fact bringing in a hotter signal somehow...though I wouldn't necessarily rule that out either, as absurd as it sounds. Though perhaps it's something about how your kernel reports or interprets the signal measured and/or how it scales the radio power?
I'm just speculating wildly at this point. When I have more time I'll do some speed tests and try other kernels and see if it's just a fluke with either kernel or not. First thing I'll check is compared to pulled stock and go from there. But, I did notice this and it seems rather significant and worth checking into.
1.0.2.2 is old.. and doesnt include these changes.

Okay, first thing. Wow. Nice work. My phone flies. Holds it rocks solid at 1.6ghz perf gov. I can really tell this phone is screamin'.
Okay, before I flashed that took my measurements again to rule out weather, randomness, etc...Then I flashed back the pulled stock kernel and had the same results I had with v1.0.2.2. Then I flashed v1.0.2.2 to make sure it wasn't a fluke. Same. Then I flashed Exp 1.0.0.8 (the latest listed on your site) and I'm still getting the same results.
It might be just my phone, it might be something in mkasick's kernel reporting a wrong number somewhere down the line. I'll stick with v1.0.0.8 for a day or two and see if there is any actual real-world differences. I have my doubts that there are.
...but there is something heavy duty and psychological about having 2/4 bars instead of 0, even if the 3G performance is identical. Luckily my desk at work and at home are in some fringe areas reception wise...so...if there is an actual difference I'll be able to tell over the course of a day or two. A couple places I have to actually aim my phone toward where the tower is to even get data to move....that seems like perfect testing grounds.
Thanks
Warning: Anecdotal evidence ahead.
Okay, LoSTKernel v1.0.0.8 has been a speed demon for me. 1.6ghz perf gov hauls ass and my battery life barely takes a hit....I mean, I don't even notice a difference between 1.6ghz perf gov and 800mhz conservative gov, except in ultra buttery smooth performance. Make of that what you will.
I have experienced 3 LOS since I flashed this 5 days ago. That's 3 more LOS than I got on mkasick's kernel in over a week. Make of that what you will. It's still lightyears better than any other custom source-compiled kernel I've tried.
The signal strength (as measured in db) and "bars" thing I reported on last week remains and seems to apply in all places I've been. However 3G performance has not been affected at all. All of the wacky point-the-phone maneuvers I had to do before to get a signal I still had to do, but, in the fringe signal areas where even on mkasick's kernel I was reporting a -101db signal and getting a -106db instead I still never got kicked to roaming and everything worked the same. Make of that what you will.
I'm only trying to help here....just reporting stuff I've noticed for FWIW, YMMV, etc etc etc.

I can't get Titanium Backup to work on Fresh 3.2.0.0 (believe me, I've tried it all) and I have wifi connection problems on CM6 with my school's network. Don't recommend DC because it is essentially dead. What's a solid, regularly updated ROM?

Well when they've pushed out one measly update since Froyo was released, I would say it is fairly dead.
what would you have them update? besides some minor changes to dconfig/dc updater that could help i cant think of what they need to change to make it better. all functions work. it has all there tweaks. there hasnt been a major ota yet to add features they need to update, and it comes with a stock kernel so they dont need to re update to to put kernel fixes into it.
for me and most others i have seen post it is stable and everything works. i am jsut not sure what people feel needs to be updated with there rom. other roms use there own kernel so i can see them needing to tweak there rom for it or they are ASOP and are building things from the ground up so want to release as much as possible as the progress. for a rom based off of stock with out its own kernel that works and to my knowledge has no major rampant issues i guess i dont get why people feel they must have an update yet.

Maybe things like performance fixes, optimization, building off the latest HTC build (like Fresh). There are a million things you can do to a ROM. The old DC ROMs got constant updates.

Do you have bad performance with dc? i do agree they could make an update to the leaked ota ala fresh that would be nice to see but i wouldnt call it dead because they havent updated to using it yet (i believe only FRESH has so far) it is relatively newly leaked.
As for performance and optimization are there specifics optimizations or tweaks you feel it doesnt have that will a make big difference? I follow all the top 6-7 roms and flash each rom as a new version comes out. (i will say havent gotten to flash fresh 3.2 yet) Besides CM which is specifically built for speed i dont feel any of them currently offer a big advantage over Dc and dc HASNT updated.
i guess to each there own. i am sure they could make minor tweaks and changes and release more frequent updates. I am sure many would be much happier. For me personally i like having a steady true daily driver that doesnt change every few days with minor often unnoticeable tweaks.
I didnt object to you not liking DC each person has to find the rom they like i object to people calling it dead because they havent put out an update every week.
my recommendation on EVIO still stand of all the roms i have used (all the top name roms except the newest fresh) i find it is the only one that has made me debate switching to it as a daily driver.

one of the big differences i like is that dalvik is on the cache partition. I like most of the tweaks he has made to the system I am not sure what all of the are but the roms seems very very smooth and i get comparable battery life to DC on battery saving profile (no other rom i have tried has given me this). With most roms i have at least 1 or 2 issues with something (though many are minor). I remove sense and htc apps/widgets usually and after doing so it seems to preform better then ava did for me.
I also believe he modifies the King kernel to tweak set cpu settings and a few other things to try to optimize it for this rom. I know he has in the past (not 100% if he changed #8 with the new 1.2 release).
overall i think it is very similar quality to Fresh. the difference for me is that my battery life is ok with fresh but good with Evio (same set up).
What's up TheBiles, I remember your thread early on about battery life improvements with autostarts and setcpu.
I'm having good results with the BakedSnack series. Currently on 1.5 using Kings BFS #6 Kernel. I would be on 1.6 right now if I wasn't doing a battery calibration for a new battery I got.
I think it's one of the most active ROM's out there, 6.5 updates since Froyo has been released and each update has been an improvement with thoughtful changes. You only need to look at the changelog, from 1.0 and on, in the thread to see what separates it from other ROM's.
Unlike some other ROM's, he isn't just updating system APK's and increasing the version number - he's really putting in the effort to balance out stability, performance, and battery life.

I'll have to check that out! Right now I was testing out Ava-Froyo for the sole reason that it has the same name as my daughter.
so i just got this phone the other day and already rooted.
Just wanted to see what roms you guys are using and are your favorite
Starburst, Midnight and Calulkin's roms are the most popular ones. However, I prefer to stay on rooted stock with Lostkernel.
Sent from my SPH-D710 using XDA App
yeah i just installed calulkin's and its pretty good im going to try starburst and midnight probably tomorrow.
thank you.
I've had it a week...been running Starburst for 5 days & like it a lot! Biggest single feature for me is the Lockscreen customization (well, & of course free tethering...but I'm pretty sure they all offer that). Being able to unlock phone directly to an app (camera for me) dramatically improves this device's functionality for me.
I did have an overheating issue last night...going to try to replicate conditions & see if it was a random thing or something that is consistent.
Starburst seems popular. I'm running a stock rom. I don't see an advantage yet to changing roms. I will wait until the roms are more developed and most of the bugs worked out.
Until then I've been playing around with kernels. LostKernel is a good one. Zedomax another. But I've had LOS issues with Zedomax big time.
I'm on EG30Plus+. Its a stock Kernel that is modified a bit, as I heard of all the LOS issues related to using completely modded kernels.
Although I must admit I've had LOS even on EG30Plus. Time to call Sprint for that credit
I am running Steve rom and it is very good. But calukin and starburst are very good to
Sent from my SPH-D710 using XDA App
I really like StarBurst. I have not even tried any others yet and see no reason to do so. First, I installed LoStLernel, which pretty much effectively eliminates LOS (or at least your perception that it occurs)... it also adds many improvements aside from that... an cleanly wo unnecessary tweaks. Then I flashed StarBurst 1.9.0/5, and have noticed a vast improvement in WiFi funcfionality (it actually connects quickly & works consistently). I researched all options quite a bit & these two solutions seem to be the most refined and professional in my opinion. This ROM is more an enhancement of vanilla than it is an overhaul. After a week, I am very satisfied. HTH

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.

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 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.
I haven't seen any posts about DroidTheory's new Axi0m/AOKP kang.

Its marvelous. I have flashed many, many roms on my LTE Gnex and this one is BY FAR the smoothest and fastest available. Everything is so quick and snappy. In my opinion it rivals the CM9 nightly in terms of speed.
The newest version, updated yesterday, tries to completely integrate 4.0.4 with the most recent AOKP. Some things don't work, like market restore, but it's definitely worth taking a look.
EDIT: Forgot to mention, this rom uses franco's kernel.

Which makes it a hackjob at best. There is no 4.0.4 source, so I am thinking he probably used dex2jar and tried adding features from it. That will not make a rom faster by the way
Never underestimate the power of placebo. If it feels faster, its due to the kernel. Everyone always says it is not a placebo, but the Beats port is a perfect example. Measured responses show zero change, yet people swear by it according to their feelings.
I am not saying not to try it, I am saying if you think its faster, its the kernel or placebo.

Thats the problem with placebos. The more people believe in them, the more conviction everyone has that it is real.
Look how far nuking batterystats went in terms of placebo. We heard about it for years, everyone believed it worked, and most took it as gospel until recently.
How many devs start their posts with deodexed and zipaligned for performance? Neither affect performance.
How about those that have a zipalign script every boot? Zipalign only works once.
How about the build.prop tweak of maxevents = 240 for window manager? Do you really think that setting it to 240 increases the framerate by even 1 frame per second?
Many, many placebos out there.

Have you even TRIED the rom? I would bet you have not. Why are you arguing semantics with me? You will not get me to change my mind. THIS ROM IS FASTER THAN AOKP B27.
Also, the battery life is great. Far better than stock AOKP B27. I get 10% less battery drain overnight than I did with just AOKP B27.
This is a good rom, it is faster than AOKP B27, comes with a great kernel, etc. What's your deal?
LOL...
Blind as can be. You are so tied up in your own little world, that you didn't hear a word I said. I am sure the rom is nice, but show some measurable numbers before saying its faster than...anything.
I have been around the block a few times to know when a placebo is in effect. I have even run some blind tests with kernels. I literally had a test group say they felt a larger performance difference from kernel A to kernel B. Like 30% said kernel A was better.
They were both the same exact kernel, no changes between them, both compiled within minutes of each other. Imagine their surprise when I gave them the results and explained both kernels were identical.
I am not asking you or telling you to change anything, but unless you can provide measurable results, your opinion is just that. If you like the rom, I am happy for you. Enjoy it.

Uh, I didn't 'hear a word' you said because you edited your post AT THE SAME TIME I SUBMITTED MINE.
If I had two gnex I would prove you wrong right now, but sadly I cannot.
I'm done with you. I was just trying to bring this great rom over to the XDA forums.

Then why have other developers started using Axi0ms "Th3ory Go Faster Script (Speed, Fluidity, Battery Life, RAM Management)"
Surely rom developers know a placebo from the real deal.

this script you describe here is 100% nonsense (RAM Management?) and no developer who knows "placebo from the real deal" would use a hacky script from some WinZip Wizard

I am sure the dev can bring it over if he so wishes. Why are you taking this so personally?
Not a fair argument adrynalyne.
You know me. I never play fair.
AOKP and BAMF are smoother in my experience. And the screen tweaks in Axiom caused horrible purple tinges for me.
I was an AOKP faithful, but Axiom crossbread snatched me
Was a previous Fascinate user (as a PMP-only), till I inadvertently knocked it into my bed-side trash bin and took said trash out I loved the modified ICS-based AOKP that Icy Glitch did, but more specifically their kernel that was included! When I got the Epic 4G (non-touch, don't worry lol) I started looking around and Nyan Colonel looked like my cup 'o tea with all the tweaking options Marcusant included; however, not only could I not find a working link to it anywhere but the last version wasn't even available for JB Right now I'm running Nitest (Effsi's), and that actually appears to be the only stand-alone packaged Kernel available for the D700 as well. I'd honestly give compiling one a try except I'm stuck with WWAN home internet and a 5GB limit per month that 2 others use on occasion. :crying: As such I rely on the smarts and abilities of you fine XDA'ers :highfive:
At any rate, as I've no experience with Linux I do not know how complicated these requests are, so please excuse my ignorance lol. But to me it seems like certain features (commits?) are fairly modular in nature and appear as though they are almost "a la carte". If it's harder than it sounds, by all means let me know and I'll be content with what is available.
If anyone does take up my suggestion, which not to try and dictate anything, but the one thing that is a must-have for me is Voodoo Sound. I use this Epic as a media player and not a phone, which without Voodoo Sound the audio quality (specifically with earphones) is overly-bright and defeats the sole purpose I have it for
That being said, while porting Icy Glitch (Git Hub, XDA Thread) to the Epic 4G would be awesome, I do realize that is likely going to require the most work and so I don't really expect it to happen. However, what I'm primarily interested in is the ability to LiveOC, as on the Fascinate I found that even running at 101(%, MHz?) offered a significant boost to performance, in particular I/O's. While I may not always use the max achievable overclock, I did always keep it at 101 for at least the benefits it provided, but it's always nice to have more performance available literally at your finger tips!
Nyan Colonel v5 (Git Hub, XDA Thread) had it all though, and was even for the Epic 4G! I don't know if he took it down because he moved on to the Nexus, or what Though, I suspect the fact he moved on is why he didn't reply to my PM a few weeks ago, which is understandable and I'm sure he gets asked a lot :\
As for "Custom?"... If someone has their own kernel, or have one they are working on, this would be my "wish list" of stuff to have:
LiveOC [His XDA Thread for the LiveOC Git location links to HERE (108MB), but he also has a repo for "Nexus S ICS" which if new=better then that is HERE (118MB).]
- If not part of LiveOC: Frequency multipliers up to 1600MHz for CPU w/o modifying base frequency,
individual GPU clock control (possible?), individual RAM clock control (possible?)
Voodoo Sound [For D700]
- Preferably offer a version with and without Voodoo Color, as some users need/like it, yet for me I get
unfixable color issues
Governors & Schedulers [Nitest, at least Effsi's ver, has a bunch to pick from. Can you have too many?]
- Scary gov seems to do a good job of keeping CPU freq low (100MHz vs 200MHz) and scaling up
quickly, giving me no instability problems at 1200MHz. 'fifo' sched has been working well for me, but
I was not able to notice any performance differences between any of the choices through Quadrant benchmark
USB Hub [Looking to try out connecting my Xonar U3 USB sound card for shiz-n-giggles, but USB flash storage would be a benefit!]
Latest Linaro & Linux Kernel [Doesn't have to be newest, but fairly recent would be nice heh]
- Compiled with "O3" optimization flag, as it does seem to help some.
BigMem [As having a camera is quite handy! (Not sure if it pertains to vid playback as well)]
I'm sure there is more but let's be real, I'm probably pushing my luck the way it is! lol Though if lots of people showed interest and provided more tweaks/features they'd like, I kinda think it'd be cool to have an Epic 4G "XDA Community Kernel"
Thanks! (Especially if you made it this far lol)

Thanks man :highfive: I do, too (obviously lol)
Also, thanks to whomever moved it to the right forum for me, wasn't quite sure where it belonged.
