Would love to look into some of these things, but we will need some debug info to go on. Not to mention that neither I or Mammon are in 4G areas. :(

This goes for any problem reports:

1. Please provide a copy of the log data using an app like catlog.

2. An approximate time when the event occured.

3. Output from dmesg command if you can provide it.

4. Send this info to support (at) bonsaigeek.com

thought viper had something and then you have the the nojourneling...
[Epic 4G Android Development] Randy_T:
Unless I am missing something (which is possible), the module that is part of the Viper rom (undervolt.ko) will not load in the DK28 kernel. And the source that I have found for the module is EVO specific.

Until we have source for Froyo, we are a bit stuck.

Credit where due, the no_journal concepts were Dameon's. I've just taken it and extended it a bit to get it where we are today.
[Epic 4G Android Development] yogi2010:
I've been running Viper for a while now, and BThomas22's undervolt script seems to work very well.... at times I am just amazed at the battery life(and reduced temperature of the phone)! I believe BlazeRom has incorporated that script, but I haven't tried that ROM. (pardon me if this isn't what you were talking about, lol)
[Epic 4G Android Development] MysteryEmotionz:
Didn't team viper remove the link to the rom with the uv script cause it want working?

Sent From Da Hood.
[Epic 4G Android Development] yogi2010:
hmm, not sure.... I believe BlazeRom still has it listed as being baked into that ROM, and it's definitely part of the ViperRom. the script had problems when he first introduced it, but he seems to have fine-tuned it to where it works great.
[Epic 4G Android Development] Randy_T:
Would you mind running the following command at a terminal prompt and sharing it?

lsmod

I don't even see the undervolt.ko module in the current ROM.

I just want to report that Quantum wasn't causing my phone to crash. I had put it back to stock, and I was having the same issues. Even on stock, the LCD went black. Went to Sprint, and they tried replacing the LCD, and they couldn't get it to work. Replaced my phone without any questions, and now I'm back. But, I think I'm going to stick with the stock DK28 build for now.
[Epic 4G Android Development] Razor1973:
When is 3.0 coming?
[Epic 4G Android Development] Randy_T:
As you can see, the undervolt.ko module has not loaded and if I take a look at the current Viper distribution, undervolt.ko does not exist on the ROM or in the kernel image.

I've spent some time looking into this and here is what I know:

Here are some bits from the initialization script that should start undervolt:

addr=`awk '$3 == "acpuclk_set_rate" { print "0x"$1; }' /proc/kallsyms`
if [ -n "$addr" ]; then
insmod /system/lib/modules/undervolt.ko "acpuclk_set_rate_addr=$addr"

If you go on your phone and type: cat /proc/kallsyms | grep acpuclk_set_rate

You'll see that the acpuclk_set_rate symbol does not exist. And it should not exist given that is a symbol from the Evo kernel. The script above only loads the kernel with the 'insmod' statement if it finds that symbol in the running kernel.

On the Epic, I suspect that the knobs that we are looking for are:

c0557d28 t s5pc11x_armclk_get_rate

c0557e60 T s5pc11x_armclk_set_rate

Which are the kernel symbols related to setting clock rates for the s5pc110 cpu that is in the Epic.

Knowing this, the porting work needs to be done and then we need to compile that module against a DK28 kernel source. We *might* be able to accomplish that without the official Samsung source.

But sadly, the summary of the story is that undervolting on the Epic is currently a myth.
[Epic 4G Android Development] yogi2010:
dang, sorry, you definitely lost me there, lol. i'm not a developer, so you'd probably have to talk to BT or someone else about that. i do seem to notice a difference when running their ROM though.... the phone doesn't seem to heat up like it used to, and there are times when the battery just won't die :)

Flash back to stock?

I have been having a few issues with glitches, and to be quite honest, while they are incredibly minor, and over all this is a great rom, they are driving me up a wall. How can I remove clockworkmod recovery 3.0.0.5 and reflash back to the stock os?
[Epic 4G Android Development] BBooDoc:
remove CWM

ODIN back to stock DK28 if want Froyo, or I18 if want Sprint stock. Links at beginning of this forum. Worked for me - but then I reflashed it all back to cool ROMs again.
[Epic 4G Android Development] lickarock:
Flash back to stock?

Ok, but my only concern is having clockwork 3.0.0.5 with ext4 as the recovery, and trying to flash back to stock, or any rom for that matter, that does not use ext4. Am I going to experience any issues because of the ext4, and if so, how can i downgrade to an earlier cwm or back to stock samsung recovery?
[Epic 4G Android Development] illizit:
Anyone else have issues with battery life? On the stock rom, when connected to wifi and a sleep policy of never my phone could last about 20 hours without charging. I can't even last 6 hours with this rom. I love this rom but the battery life needs to be improved. Any sugestions?

Thanks!
[Epic 4G Android Development] illizit:
When flashing back to stock with odin it will restore the partition back to its original file system (rfs).
[Epic 4G Android Development] lickarock:
Thank you very much. That was my main concern. I didn't want to end up trying to boot an rfs rom on an ext4 partition. I went ahead and tried it. Worked like a dream... perfect stock OS. Now time to root, remove bloatware, add launcher pro... basically de-stock it. LOL.

[Epic 4G Android Development] the.gwo:
I'm seeing the opposite of what several others are seeing regarding battery life. Since I flashed DK28 & quantum, I've noticed a slight improvement in battery life. Some nights I get home after a day of "moderate" use (couple of hours of music, some browsing and apps for an hour or two, a couple of phone calls) and still have >30% charge, which never used to happen.

It sounds like the battery drain is related to a specific function or app. I don't run wifi ever, so maybe that's the culprit?

after i finally got mine back to stock, i odined to dk28, then used the new one click root and then flashed str8 to 2.7. after u go to clockwork 3.0.0.5, you cant flash most addons unless they are converted to edify script. and if you try to restore an older backup, it may put u back doing your odin dance. that is what happened to me :)

also, is there a way to go back to pre-ext4? no 1 other than this rom uses ext4, i was unsuccessful in restoring (just sits there at the 'SAMSUNG' bootup screen), and i would like to flash to another rom if the GPS does not get a fix.

thanks,

[Epic 4G Android Development] magoo5289:
Yeah that's a totally known issue and a pain in the butt. not an issur with Quantom though per se.

You have to go back to 18, acquire a GPS fix, then you can upgrade it to 28 and do your ROM thing. Never made much sense to me, but it does work.

I noticed a few people mention this on he 20th, but no one responded. The battery life on 2.7 is horrible! I have two epics both came from stock odin, and they see 20% plus an hour drain while in use. I have 1hour 36 mins of use on full charge sitting at 65% battery.(nothing more than twitter app and facebook browsing. No wifi, no 4g, no gps.) The other phone dropped 15% in 1 hour 30 mins on standby.

[Epic 4G Android Development] softtrex:
+1 for the sms glitch. Just had it happen to me, message sit as "Sending..." indefinitely and the phone requires a reboot to fix it. Had this happen twice on Quantum 1.3/1.4 but it wasn't a regular thing. So far this is the first occurrence of this on 2.7 but I've only been using for about a week.

Also,

Battery life is still worse than before. After 2 calibrations already I'm still noticing it. I usually use from 100% to about 65-70% after my morning commute into the office. Its more like 100% to 45-50% after the switch to 2.7. This involves getting ready for work with minimal use (mostly only as a clock and to read the morning email) and taking a train into work for ~1 hour in which I have the screen on 90% of the time (music, podcasts, email, texting, internet use, updating apps, minor gaming/video watching, etc). I know it's heavy use but half the battery gone in that time is too much.

i've tried several different roms but i have remained with quantum rom for several months. i prefer it because it works, it's fast, it's stable, and it doesn't have a lot of extras (bootup screen & noise, in particular). my only complaint is that i think (???) i lose my gps signal more frequently than i used to - prior to rooting.

anyways, my question is...when the official froyo is released (now expected in less than 2 weeks) will i need to do anything before updating? i have never been successful in 'fully' restoring my phone. instead, i wipe it 2x then flash it with the rom of my choice then restore my data. hence, i haven't been able to go back to pre ext3, dk28, etc. am i screwed?
