[Q] CM7 based roms all cause SOD...does anyone know what's causing this?

Everytime i have tried flashing a CM7 based rom, and i've tried almost all of them, once the screen goes to sleep it won't wake up. i think that's called sleep of death (SOD), pardon my n00bness if i'm wrong. the odd thing is that when i press the wake button, the phone and even the digitizer wake up because i can hear/feel the phone unlocking when i make the sliding motion on the screen, but the screen itself will not wake up. Does anyone have any idea what's causing this? or better yet any ways of preventing/fixing this?

Do you have this issue on stock?

What kernel r u using? If u flashed uv kernel try to use stock voltage, some devices don't work well with custom uv kernels

I have this problem with all 3 kernels, stock, oc UV, and oc stock voltage .. I've had this phone for a month now, this is what makes it a waste of money for me. Even my girl has this problem with her g2x, yesterday I put cm 7.1, hers started doing it too.. and she's had 3 replacements..

Did u wipe ur data and format system before flashing? Try to fix permission too. Only guessing but maybe the battery is bad, as far as I know u not getting new one with replacement, so if u had same issue on stock rom that could be a problem.
I had 2 replacements but had that problem only if undervolt too much.

Well, I don't think its the battery dying but someone mentioned here before that if you look at the battery where the connectors are, there's 4 on the battery but 3 on the phone

No this issue only occurs on CM7 based roms, OTA 2.3.3 based roms work great

I haven't purposely flashed any non-stock kernels alongside the roms, unless all the roms i flashed included UV kernels....but i've flashed almost every CM7 based rom

I did wipe data, format system and even fix permissions and still same problem occurs, I don't think it has to do with the battery tho because stock OTA based roms don't have this issue...it must be something particular about the CM7 base
Also, could it be the fact that i have the WIND mobile optimus 2x? it says p999-DW on the back though

use miui it doesnt have the SOD problem cm7 did it the last time i had it (3 days ago)

[Question] Kernel flashing and matrix kernel specifically.

Hello everyone!
Phone: nexus s 3g running stock 4.0.3 with matr1x 14.0 kernel
my 1st question:
i was wondering how can revert back to stock kernel without flashing my stock rom again or going back to my previous backup?
i know it is very easy to switch from kernel to kernel but i would like to know how to switch back to my stock kernel. If you come across a link please send it to me. Thanks much appreciated.
my 2nd question:
my phone reboots the 1st time when loading up matrix kernel.
what happens is i press the power button .. the phone boots up normally then halfway through the animation it gets stuck and the phone reboots BUT this time the boot animation works properly and i am finally booted to my phone. Note that i have absolutely no issues running the kernel + BLn + Voodo etc (also not oced either)
question how can i solve this? is it normal?
I have one last question (sorry lol)
about voodo colour is there anyway of removing the grren flash that i get from unlocking the phone.
i know i can reset to 2.3.3 colours and that does do the trick but i would like to use my own custom settings..

stock 3.0.8 kernel can be found here in 3rd post
http://forum.xda-developers.com/showthread.php?t=1399273
Questions regarding matrix should be asked and may already be answered in his thread
And green flash is common on kernels with voodoo it also turns screen green occasionally for me when auto brightness set
not sure how to fix haven't researched doesn't bother me that much
Sent from my Nexus S using xda premium

Alright...
First off is this a specific rom? Like kustom kream, nexus beam..
Or just stock ics rooted
Second, try this again.
Get the rom zip again, then get the kernel zip again.
1. Wipe data, cache, and dalvik cache
2. Flash rom
3. Set up rom
4. Go back to cwm
5. Wipe dalvik cache
6. Flash kernel
7. Reboot
Did you do it like that?

Green flash can be fixed by downloading the voodoo control app in the market then going to the RGB profiles then selecting the voodoo profile

Green flash can be fixed by using either 2.3.3 colors or punchy

im on offical ICS 4.0.3 rom stock (rooted) with matr1x 14.0 CFS
well i downloaded matr1x through rom manager and after wiping dalvik cache i flashed the kernel.
is there anyway of fixing without clearing data? i have a lot of stuff on my phone i would rather not erase... also im on stock ICS so how would go about flashing it again(its not like a rom i can just dl and install or is it)?
speaking of which i know titanium backup backs up apps but does it also backup like my contacts, sms and phone settings etc?
update: i went ahead and only deleted cache and dalvik cache and then installed the kernel again. same problem =/

exact same problem ....
followed ur steps perfectly.
anyways i just restored everything back.

im 16 aswell i dont even know the 1st thing about making kernels and so forth lol.

Lol sorry you couldnt get it to work...
The only other suggestion I have is to try another rom...
Sent from my Nexus S using XDA App

thanks for trying .
anyways the thing is the kernel works perfectly fine other then that and sinc ei dont reboot my phone so much its really not an issue for me.

just another quick thing since that is the only problem i have experienced with the kernel and that everything else is fine working fine should i be worried about stability?

No, the kernel is pretty stable out of the box.

yes, I have heat, but not that really hot, just a little warm when work with it more than 10 mins continuously like gaming, facebook or sth...so, it's not a big deal but battery I think I can deal with things in 24+ hours so, it's great ^^ (stock 1650 mAh fyi)...anw, has someone tried tweaks like A.S 15 beta or Supercharge or Lagfree 2.1 on CM7 yet? I applied those but don't know if they're working or not since there's nothing remarkable
Haha, after I've flashed so many roms and many times, seem like my phone now have 000...00 imei for permanent lol (forgot to backup things ^^) so, be careful men
Edit: after flashing CM7 again by FB CWM method (via CWM), the IMEI is back @@...my phone was really got me =]]

DO NOT use those tweaks on CM7. They are not made to work with CM7 and may cause issues.

Yes, flash a one click that comes with a custom kernel built in, and make sure that if you made the backup in RED cwm you restore from RED cwm

I seem to be getting inferior battery life on CM7 compared to VB w/ AntonX's kernel, with about the same amount of usage. Anyone else notice this? I'm guessing this is mainly down to the reversion to a stock kernel. Are there any tips for battery life specific to CM7 and besides the usual ones (e.g., battery apps, screen brightness, turning off mobile networks)?

CM7 will be worse on battery until they get all the kinks worked out. You might still see less battery over a custom modified stock rom.

Weird thing happened to me..from miui when I downloaded the files rebooted to recovery it booted into blue cwm so since u said that I thought ill just backup then do a red cwm since it wouldent let me flash..got on cm7 with no problems thanks guys

Try fix permissions and reflash gapps zip. If it doesn't work you might have to repartition SD card from CWM and reflash.

I'm having the same problem with Scott's Stock Rooted VRALHE & his individual mods that I installed which include the 15 toggle, the 3 button power mod, no power up sounds & stock samsung animation.
I'm going to reflash the VRALHE again tonight without the mods and I'll report back.

I tried reverting back to a nandroid backup I had before I loaded the mods and still had the issue. I tried researching it before posting and someone had the same issue until they reformatted their memory card so I tried it but still no dice.

Take a look at this thread, it worked perfectly for me. As I understand it, it contains a firmware update for the radios and other things that was part of the OTA, but not the part that the flashes are built on.
Anyway I had the same problem and my HE is now sleeping like a baby.

Having minor issues on Synergy

Hey everyone. I'm running the latest version of Synergy and I've been having some issues. First, every now and then my screen will freeze and the only way for me to correct it is by locking and unlocking my phone. Second, I noticed that after a reboot my battery percentage is no longer showing. I have to go into settings and uncheck and recheck the option to display battery percentage. Lastly, after I reboot I've noticed that my default input method (which is swiftkey) will be changed to the Samsung keyboard. Again, I have to go into settings and change that as well. Does anyone know of any fixes for these issues? I've reflashed synergy several times and I still have the same problems. Any help would be greatly appreciated. Thanks!

For SwiftKey back it up with titanium Backup delete the app and then restore it, you won't have that problem anymore.
For the 1st one it really depends on the kernel you are running, you try various kernels in the original development section for this device.
As for the percentage I am unaware of that as I do mot run that rom.

Im curious you're original flash method. Can you describe what rom you were on before and how you got here? What in getting at was did you wrote data/cache/dalvik a couple of times each? Also have you tried redownloading the rom and clean flashing it?
Sent from my SCH-I535 using Tapatalk 4 Beta

I was stock before synergy. When you flashed this rim it gives you the option to do a superwipe. I did that plus I wipes cache/dalvik/and performed a factory reset before doing the superwipe. I'm not sure on how to get 10 points so that I can post this in the synergy thread.

You can always try since all phone play on kernels differently first try a 25 step and keep going up once you see the freezing stop, but keep in mind some kernels may not be for your phone so it's always good to experiment with other kernels to find your best battery and performance results.
Sent from my SCH-I535 using Tapatalk 4 Beta

Thanks for the suggestions. Where can I find other kernels? I'm going to play around with the ziggy kernel to see if I can fix the freezing.
