[Q] CM7 Modem- does it matter? - Epic 4G Q&A, Help & Troubleshooting

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.

new sprint kernal vs cm6 on batt life

i have been running flipz newer rom with the new unreleased kernal and my battery life is AMAZING, I mean very very good. I was thinking about giving CM6 a try again with flashing the new v7.6 kernal thats supposed to be really good.
But I was wondering what people are getting with cm6 and the kernals as far as batt life.
Ive never personally flashed a kernal before so not sure on how well or how much they affect the phone or if its worth it.
any help? like as far as the best kernal for a CM6 rom and and reports on batt life comapred to the new leaked kernal
I'm getting better battery life on stock now, then I was on any other modded kernel (kings, cm6, and some others.)
Nand backup and give it a shot. It seems way to better to me than stock or even cm6 nightly with newest kernel.
also whats the difference between bfs and cfs roms?
i feel batt life with CM6nightly + snap7.6 in turbo mode is about how the phone was when it was first released...you can make it a day with light use, but using it a ton, i seem to get around 8-10 hours.
However...getting 2600+ in Quadrant and no lag, anywhere, ever...makes up for it. I'm always within reach of a USB port or wall outlet so i just carry the charger/cord around with me.
I haven't actually ran it from full to dead outside of work. However at work i constantly drop signal and regain it repeatedly for the 8~ hours i'm here.

[Q] New to the Dinc. Need Advice?

I'm an og droid user but just picked up a Dinc for my fiance. She loves the thing but hates the 10 hour (9 hours of that is idle?) battery life.
Last night, I went ahead and rooted it and removed most of the verizon crap-ware and then adjusted her sync settings to hopefully improve her battery life. I also did a battery stat reset.
She loves it as-is so flashing roms is out of the question. I don't have time/she doesn't have the patience for me to flash roms and fix problems that arise. With that being said I would like to explore the other back-end options.
Now, keeping in mind, this dinc is completely stock. Stock sense, stock kernel, stock radio, etc. I've been advised to replace the stock radio with one from Doug Piston. I was told to install the 04.08 version for the EVO. I just want to clarify that this will work for the Dinc running stock froyo sense? Also, if someone could tell me exactly what this does? Is the main benefit better battery life? Or something else? Also, if this is not the correct radio I should install, which is?
My second question is in regard to a better kernel. As stated above, I am stock and will remain on stock sense. What are some good proven kernels that will work on stock sense. Performance on the device is fine, so I'm not worried about that. I'm only looking for a kernel that will boost battery life. I looked around here but I couldn't determine which of these, if any would work on a stock Dinc or if they were just for custom roms?
Anyway, that's all. Thanks in advance for any help on this!
Here is a link to all the different kernels that are available for the Inc. It will say if it works with AOSP or Sense. Just take a look through them and see which one would work the best for what you want. Some will overclock, some will underclock, etc
http://forum.xda-developers.com/showthread.php?t=866736
Whoops didn't notice you had that link already. Some popular ones are incredikernel and heyitslou. I know with incredikernel I was getting good battery life but also was with different ROM not sense.
I have installed a radio on my Inc, been quite fine for the last few weeks as well. From my understanding, the radio may or may not improve gps lock and/or your phone's signal strength depending. This is hit or miss, not everyone notices a stark improvement in both or either category. As such, if you already have poor signal in your area it may not improve your signal therefore it has no effect on battery life.
Someone more knowledgeable in that area please correct me.
You can try whichever radio you desire, I recall many people using 4/08 or the 11/19. Personal preferences aside, your improved battery life depends on how much signal your phone reports that it is receiving.
I have used the heyitslou kernels and have loved the battery life I got with it. I have also upgraded my battery to the 3500mA battery. This did wonders
incredikernel w/ smartass + CM7 and never look back...i know you like the ROM but i think stock sense is what drains the battery the most.
I've had good luck with Lou's kernel running a sense rom.
may want to try Virtuous v3.2.0 its a good stock rom with some clean-up done.

Battery life issues! Possible kernel and wake lock?

Ok so im not new to rooting as I have owned a Hero and an Evo 4g for some time. But now I am running an epic 4g and I am having terrible battery life throughout daily use.
I am running the leak of the stock build EF02 and the light tweaks that were in the forums such as ram booster. After checking my phones up time it says it is 14 hours. Which means that it has not slept and clocked down sine last night when I put it on a charger. This is obviously a kernel and/or radio issue. But the problems is I need to know what radio to flash to fix this. There was a very similar issue with the Evo when it ran an incomplete gingerbread kernel: Flashing a new radio fixed it.
Can anyone give me some info and input on this subject because I think if Im getting this problem then there are a lot of others who have it as well.
Thanks

[Q] EG22 VS ECO5 Running srf 1.2?!?!?!?!?!?

Im reading a lot of talk about the eg22 mod. I know everyones phone is different but which do you guys feel is better personally for you? Im currently running sfr 1.2..with the vision kernel. I guess what im interested in is of course batt life and are you guys really getting better signal overall? I read past posts but i would like to know currently whats going on and if so...where is the current version of this infamous eg22...thanks!!!
You can flash the EG22 modem, while keeping sfr 1.2.... what they are talking about is modem performance, not rom performance. Try it out. Just odin the EG22 Modem.bin to your phone.

Yuh..i just watched qbkings vid of course...im running eco5...u feel like its worth a try is what im asking?
Always worth trying. You can switch back. Mine seemed to drain battery quick, but got super strong signal... May try again soon.

I find it quite stable on my phone. It's almost like your phone chooses the kernel, at times.

lol I completely agree. My phone totally hates the twilight kernel, IDK why. I tried it out twice and every time its just so laggy and lots of force closes. But with Genocide its just fine.
Anyway, back to the EG22 modem. I also found that it took a little bit more battery (even during standby) because its a little overzealous, however it did consistently get me better signal. I'm sticking with it for now because the battery drain isn't so bad unless I'm in an area with terrible reception. Give a try, you never know

I'm on SRF 1.2 w/ Genocide 2.0.
Just for kicks, I took a few seconds the other day to flash in the EG22 modem...My experience so far has been quite positive.
We're staying in an area right now where the signal strength tends to be rather low which means my tether can be frustrating at times...Since EG22 modem, my connection has been much more reliable.
I can't really comment on the battery because I'm on the USB tether a lot...Besides, I've gotten in the habit of simply carry a spare battery with me...Although, my overnight battery drop has only been about 5%.

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.

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.
