[Q] Screen flickering during boot. - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

If there already are threads about this, please direct me to them instead of flaming. I have searched through the forums without finding anything.
I got my 10.1 WiFi about a month ago, and can't figure out why this is happening, and if it is happening to anyone else. Every ICS rom I install makes the screen flicker during boot, and it will continue to flicker until I turn off the screen, and then back on. After that there are no problems at all. I had the same issue when I install CWM recovery. I had to try 3-4 different ones, before I found one that didn't flicker.
It seems to me, that it might be kernel related, but I am not sure.
Any input is welcome.

Same here, even 3.2 ROMs flickering for me . The only one that doesn't flick is Task ROM

Hey man, just got this sorted out
Try to follow this http://forum.xda-developers.com/showthread.php?t=1555984
Key part is that we need to unroot our tabs with North America stock. I think our "Non-NA" stock ROMs weren't really "unlocked" that's why custom kernel won't work well on them.
Super happy now with CM9 + latest pershoot kernel + latest CWM, smooth no flickering
Happy unrooting !

Make nand backup (if recovery flickers use rommanager)
Save it to PC
Wipe everything
Flash P7510UEKMP_P7510XABKMP_XAB.tar.md5 with odin
Reboot
Wipe everything again
Flash recovery.tar.md5 with odin
Reboot
Put this http://www.shabbypenguin.com/users/s0ckm0nk3y/android/acs/galaxytab10.1/Samsung_Galaxy_Tab_10.1_root.zip to storage
Put nand backup to storage
flash the zip
Reboot
Restore nand
Finisch! You can now flash another recovery and any other rom without flicker
In fact there is no way to get the flickering back^^

ive had the same rolling screen during boot, but recovered with those instructions.
now i have another kind of problem:
roms flash ok, cwm is ok, boot is ok. but when i get to the desktop, if the device goes into standby, ot if i put it in standby withthe power button, when i wake it up, again a rolling screen, but much faster this time!

Hello all.
I have the exact same problem as tristan202 which is
Every ICS rom I install makes the screen flicker during boot, and it will continue to flicker until I turn off the screen, and then back on. After that there are no problems at all.
I am sorry but i think that solutions bringed by "hylde" is not related to this problem but to another problem, through very similar, in clockwork recovery tool : same flickering screen.
I used the link, 2 weeks ago to solve this problem, using 5.5.0.4 version.
But the original thread problem is still unsolved. I tried other ICS roms but with same problem. I'd also like to keep root access.
Thanks to all

Well, I have almost the same problem. I am on overcome's rom, and I have a screen similar to yours. It is static, not rolling and it happens only once after reboot for two-three seconds before the lockscreen. After that it is ok, even when I lock the screen. Flashed again but nothing. I haven't found anything about that. Oh well. It may be weird but I can live with it. Has anyone encountered something like that before?

Put it at the Root of your tab and reboot into recovery, then flash that zip file!
You should be good to go!
If not then you will have to flash back to stock kernel listed at the bottom of the second post or just re flash the Rom your choice, this will be nessesary if you flashed another kernel, Then go back and flash boot-cm_2636.4_ux_hc32-oc-xtra-vfpv3-d16_fp-010912.zip then you will be GTG!

[HOW TO] Install EB01 ROM with SlicedFlav or Stock

Excited to give you guys a walk through again. I have included my hybrid flavor of the EB01 stock ROM. I have kept TouchWiz on there but removed all bloat ware and dibinged the phone. I have also included the Gingerbread keyboard apk (separate install, I just love this keyboard.).
Give the shout out to the originators of this information. XDA is a great site.
Don’t worry, I have a link for the stock too.
First this will assume that you are on the DL30 leak. This is for the Fascinate and no other phone. I am not responsible for your doing. This is what worked for me.
If you are not up to the standard above click here: http://forum.xda-developers.com/showthread.php?p=11177786#post11177786
**********************************************************************
I AM NOT RESPONSIBLE FOR YOU DOING. THIS WILL VOID THE WARRANTY OF YOUR PHONE.
THIS IS JUST THE STEPS I DID TO GET MY PHONE TO EB01 FROYO.
***********************************************************************
You will need the following items:
Samsung Drivers
Odin 1.3
eb01modem.tar
update.zip
cwm_froyo.zip
eb01_SlicedFlav_pub.zip
OR
eb01_stock.zip
Now follow the below steps
1.] Download and install the Samsung Drivers
2.] Connect your phone to your computer and copy over the update.zip, cwm_froyo.zip, eb01_SlicedFlav_pub.zip (or) eb01_stock.zip to the “ROOT” of your SDCARD.
3.] After you download Odin and eb01modem.tar put them in the same folder.
4.] Disconnect your phone from the PC, power off, and pull your battery out. (It’s the easiest way)
5.] Plug in your phone while holding the volume down and turn the phone on. You will see a yellow triangle
***************************************************************************************
THIS IS IMPORTANT > DO NOT TOUCH ANY SETTINGS IN ODIN, ONLY USE THE PDA BUTTON AND THE START BUTTON.
IF YOU TOUCH ANY OTHER BUTTONS IN ODIN YOU COULD BRICK YOUR PHONE.
***************************************************************************************
6.] Launch Odin as administrator in Vista and 7.
7.] Select the PDA button. AND ONLY THE PDA BUTTON, YOU CAN BRICK YOUR PHONE.
8.] Select the “eb01modem.tar” file.
9.] Click on “Start”.
10.] You phone will shut off, give it a min or so and it will boot back into download mode.
11.] Unplug your phone, put your battery back in, and boot into recovery mode by holding volume up and down while pressing the power button. Let go of the power button when you see “Samsung”.
12.] Scroll using your volume up and down keys. Highlight "apply sdcard:update.zip” and use your “Home” key to select.
13] Now you want to “wipe cache” twice for good measure. Highlight “wipe cache” and use your power button to select now. Scroll down and select “Yes” both times.
14.] Now you will want to “wipe data/factory reset” twice. Highlight “wipe data/factory reset” select it, and then select “Yes”.
15.] Now you will want to select “install zip from sdcard” then select “choose zip from sdcard”.
16.] Scroll down and select “cwm_froyo.zip” and confirm it. The screen will go wonky for a second.
17.] Select “choose zip from sdcard” again.
18.] Scroll down and select “eb01_SlicedFlav_pub.zip” or “eb01_stock.zip” confirm your selection.
19.] Let it do its thing and boot up.
You now have the way SlicedDrip feels the Fascinate should be and the way Verzion thinks it should be.
Have fun.
If you want the Gingerbread keyboard, download it HERE, move to your phone, use your favorite file manager, browse, and install.
The following only applies to the SlicedFlav install:
ITEMS REMOVED:
All VZW apps
Blockbuster
Media Hub
All Share
Samsung Keyboard
My Files
Write and Go
All Demo Gams
Nuance
Buddies Now
City ID
Skype
Kindle
Most live wallpapers, kept default, when I removed it would give me errors on first start up.
Visual Voicemail
THINGS STAYED / SAME:
TouchWiz
Debinged Browser
Third party sync application
Swype

Is this rom able to keep perfect time with verizon's updater?
the other roms like jt's and adrenalyne's has a time lag which i'm so annoyed of. Please confirm by downloading clocksync and check if it's consistent.
Also, it seems like the cwm.zip or the update file from adrenalyne's doesn't work with your rom. corrrect? It's stuck on the samsung bootup screen.

I will have to check on the clock sync.
The files I have linked in my original post are the ones I used for my phone.
What are you currently running. The only thing I did on my flavor ROM was delete files from the stock version (it is linked on the original.)

I just got your rom flashed on my phone. It seems like the clockwork was the problem. I came from adrenalyne's EB01 2.3. The clockwork I was using was an older version of JT's. Your rom ONLY works with JT's new ALL_FROYO_CWM and presumably the one you posted on this thread.
Onto your rom... IT'S PERFECT (so far). Seems like the battery lasts longer and there is no time lag... but what do I know, I only had it for an hour. I'll reply once I spend more time with it. If it's consistent, YOU HAVE THE BEST ROM FOR SAMSUNG FASCINATE AT THE MOMENT!!!!!!
Was easy to install man.thanks for your hard work and time. Noticed the update.zip you has on the op didn't work for me. Had to use my original cwm update.zip and when in contacts the back button wouldn't exit the contacts menu. Peace out, achron

FOR EVERYONE WHO'S STUCK ON THE SAMSUNG LOGO. FLASH CWM THROUGH ODIN (the .tar file) from here http://forum.xda-developers.com/showthread.php?t=942021
and then flash the rom through cwm.
REVIEW: IT'S EFFIN PERFECT!!!
TIME IS PERFECT (no time lag like every single other rom), BATTERY LASTS FOREVER!!! TOUCHWIZ IS REALLY NICE WITHOUT BLOATWARE AND YOU KNOW IT!!!! FROYO FTW
I've tried every single rom from JT's and PUNK KAOS and ADRENALYN'S. This one actually works flawlessly and doesn't have any problems with it. MARK MY WORDS!!! The other roms will burden you with either time lag, few hour battery, not working hardware, etc. BELIEVE ME!!! this is the only rom that was MADE for this phone. THANK YOU man.

While I appreciate your opinion and review of the ROM directly comparing it to other ones can sometimes feel like your slighting those devs so yeah, this rom is terrific I've used it, but I've used the other ones you've listed as well and I think they're just as good, directly comparing them like this is for lack of better words rude as you're dissing someone's work that they made for you for free.
So yeah, I just had to let that out because I've seen such criticisms of other dev's roms a lot recently and it bothers me. They're working for free, you might like one better than the other, but really its not smart to try to say one thing is better than the other period, or that a rom is bugged and doesn't work and lags etc etc its just rude.

theres nothing in this rom that would significantly affect battery life one way or the other...really only undervolt kernels will do that...and we dont have them for froyo yet.
and you do realize that jt, pk, and adrynalyne are responsible for virtually everything on this device and that anything built is just variations on what they have done. theres only so much that can be done to a touchwiz based rom, so anything that does come out will, again, just be another variation of what has already been done.
nice work by the op of course, but get some things straight.
(not to discredit the work of birdman, et all just these 3 were mentioned)
hmm.... I wasn't criticizing the developers themselves (sorry for leaving birdman), but the roms themselves
I was just frustrated I missed some important meetings because the alarm didn't go off due to the time lag.
Anyhow, this rom, a variation of the top 4 developers, turns out to still have the time lag. It was off by a whole 30 minutes this morning. Seems like all EB01 and DL30 has this bug T T .
any remedies? I remember punkkaos' rom not having time lag,,, but.. well, you know.
at least the battery life improves. here.
What do I need to do if I am using the Dj05 build to install this?
I find it amusing that you would blame any dev for the time lag issue when its a bug in dl30 and eb01. It happens even on the stock roms. So point your frustration at Samsung.
As for battery life, to each their own. We all use the same kernels, radios, and battery drivers.
Sent from my perfectly clock synced superclean 2.4.
Have you removed the extra libs and framework files associated with the apps that you removed from the ROM?

so sorry adrynalyne. I unintentionally misdirected my anger. I should be angry at my fellow koreans T T, Hopefully you read this and forgive.
I actually fell in love with your rom again after you added the 5 lock screens at 2.4 (Im weirdly addicted to a message shortcut from lock screen)
Hopefully another driver or gingerbread will somehow improve battery. The 3500mah batteries they sell on ebay don't look so pretty.
There seems to be a variation with the time lag. Some of my friend's fascinate are always fine, some aren't

The GPS Won't Lock (Already tryed gps.conf, fasterfix, gpsfix, without luck)...HELP!

Hi everyone!
Well, I live in SouthAmerica (Argentina), and I bought an unlocked AT&T Atrix 4G a couple of months ago.
When I was on the stock Gingerbread Firmware, the GPS worked Fine. But when I unlocked the phone, and started playing with ROMs, the gps stopped working.
Currently I have CM7 Weekly #4, but i previously had: Wet Dream V1.3, CM7 Ba2TF, CM7 Weekly #3, and the issue was present on all of that roms.
I tryed with the proper gps.conf configuration for my country, and a lot more, and none of them worked or improved anything. I also tryed with the following apps: Faster Fix, GPS FIx, GPS Status, and again, none of them worked.
So, I was wondering (If there isn't any other solution): Can I go back to the Official AT&T Gingerbread Firmware (.SBF file), or I will brick my phone?
If so, anyone knows where can I find that SBF? Because all the links I saw were on Megaupload, Filesonic, Fileserve, or similar, and all of them are down, or restricting the download.
Help will be highly appreciated!

flash a stock rom SBF file using RSD Lite should be fine. But don't go back to Froyo, any Gingerbread stock roms should be ok.
Well, i installed the SBF, and now the GPS works perfectly...
Why It doesnt work in custom Roms?

Hi,
Could you please try Neutrino V2. 1p rom?
There is a gps tweak in add-on.
First, flash the rom and test the GPS.
Then if it work, flash the add-on.
But for me it's another problem, it's really strange...
Do you full wipe (with fastboot) before flash?
Let me know by PM, I will not follow this thread carefully.
We will found a solution ;-)
Regards
-JFK-
I have the same problem and tried everything like the posted said above.
Running Cyanogen 7.1 on AT&T (USA)
Wish I could be more helpful, but I can at least confirm that the GPS works fine for me running cm7 weekly #6 with faux123's 1.3 kernel (on an AT&T Atrix). In flight mode (i.e., no data and thus no A-GPS or other location assistance) I can get a lock in less than 10 seconds with a good view of the sky.
I do not know if you tried reflashing your radio as discussed in the atrix-dev-team faq:
code.google.com/p/atrix-dev-team/wiki/FAQ
You say you have tried various firmwares but didn't mention what kernels you were using. If you are using the stock kernels, the faux123 or Clemsyn kernels might be worth a shot . . . obviously you need to flash the right kernel (i.e., if you are using a cm7 firmware, use the custom kernels specifically built for cm7).
If you already tried all this, well, sorry . . . give -JFK-'s suggestion a try.

I tried the Neutrino ROM GPS fix, it worked amazingly. My phone was taking forever to lock, so I flashed the United_States.zip file from the GPS fix, and it solved my problem. Used GPSFix app from the Market/Play Store to finalize it.
I'm running Ba2TF Beta 3 (CM7.1).
Again, this file is only for the United States Atrixes.
had the same problem with the phone since first day i started using custom roms,
but i managed to solve it a few days ago..... what i did was
go here
http://forum.xda-developers.com/showthread.php?t=1252011
and download the 3.x Google Specific CWM Flashable build there
or just click this direct link http://derekgordon.com/gps-files/agps.patch.google.build.cwm.v3.1.zip
flash it with CWM,
then using root explorer, go to your phone system\etc\
and open gps.conf with text editor,
with in the first few lines, u will see this
NTP_SERVER=ntp.derekgordon.com
Click to expand...
Click to collapse
there is only one NTP server,
so go to http://www.pool.ntp.org/en/
and under active servers, select your sub-continent and u will some ntp server addresses, add that to your gps.conf.
than go into your country specific link and add the ntp server addresses u found there into the gps.conf file as well.
if you follow those steps correctly, your NTP server list for gps.conf should look like this for Argentina
NTP_SERVER=ntp.derekgordon.com
NTP_SERVER=0.ar.pool.ntp.org
NTP_SERVER=1.ar.pool.ntp.org
NTP_SERVER=2.ar.pool.ntp.org
NTP_SERVER=3.ar.pool.ntp.org
NTP_SERVER=0.south-america.pool.ntp.org
NTP_SERVER=1.south-america.pool.ntp.org
NTP_SERVER=2.south-america.pool.ntp.org
NTP_SERVER=3.south-america.pool.ntp.org
Click to expand...
Click to collapse
now go stand somewhere with open sky as sometimes buildings block the gps signal so it can't get a proper lock,
cross your fingers and activate your gps and hope it works....
and don't forget to leave the gps open a few mins for the first time you activate the gps after the above steps
as i remember reading somewhere in the AGPS original post that it kinda help the gps locks faster.....
if u are geeky and wanna know how many sats ur GPS is locking on,
download this neat GPS tool https://play.google.com/store/apps/...wsMSwxLDEsImNvbS5lY2xpcHNpbS5ncHNzdGF0dXMyIl0
and see for yourself and while you are at it, u might wanna calibrate your compass for faster and more accurate GPS lock,
which can b done from (menu button)\tools\compass calibration
might as well do the 'calibrate pitch and roll' too,
but don't touch the 'manage A-GPS state' unless u know what u are doing as i have no idea what it does...
if you really wanna know how AGPS works, just go read it's original post here
http://forum.xda-developers.com/showthread.php?t=1252011
cause i dunno how it works, i just know that my gps works after flashing and tweaking it
I have also been reading that switching radios can help the gps signal lock. Might be worth your time to look into it as well.
I had this issue just the other day and i just had a setting unchecked were it wasnt useing the interal gps for the lock not sure how that happend but it fixed my problem

Thanks.
I looked at this. I've since switched to Neutrino but same problem.
In my settings it provides the option to use internal GPS (as the only option) but even when selected the GPS source states ""use external bluetooth gps..."
Could this be the issue, that for some reason it's not detecting GPS hardware?

[Q] Phone Randomly Shuts off on Wake - ARHD GB to ARHD ICS

Trying to diagnose a problem with my Brother's phone. He got his Amaze about 8 months back, no issues whatsoever on the Stock ROM other than a backlighting issue on the bottom buttons that HTC is aware of.
Since installing ARHD Gingerbread, he gets random, and frequent phone shut downs when trying to wake it from lock/sleep statuts. The phone just shuts off and restarts by itself.
We were hoping that migrating to ARHD ICS this week would solve that issue, but it has not. It still shuts down randomly at wake.
Something on your phone is probably causing this, do a full wipe and reinstall.
I was actually experiencing this last night. Happened about 7 times while I was at work. After I cleared cache and dalvik-cache I fixed permissions. So far it hasn't happened again but waiting to see if it does. But maybe our issues maybe totally unrelated. I didn't pull a logcat to see if there was anything that maybe causing it. Next time it does I will.
Running ICS .3 Stock debloated, no scripts but with a theme. But its been on there since I flashed the newest ICS RUU so it can't be that.

Except it has done this multiple times after using superwipe, with both ARHD Gingerbread and ARHD ICS.

I'll try this. For whatever reason the RUU on the ARHD page continually fails to update via ADB/Fastboot, I'll try again to see if it works now that ARHD ICS went on it successfully. Will try the Cache Clear and Permission Fix - definitely didn't do that after flashing this.
Weird update. In his bootloader it always said unlocked. I did the S-Off method advertised by JopountBear (sp), but now it seems it is locked? Odd.

Radio still won't install - says remote: not allowed.
Doing one more superwipe -> ROM -> Cache/Dalvik/Permissions Clear. Battery life very bad at the moment (But perhaps Battery Calibration is off?)

You didn't point this out in the beginning, if the bootloader is locked it won't allow flashing, re-unlock to flash whatever radio you're trying to flash.
Out of curiosity, why would a phone re-lock itself without me telling it to do so?

the bootloader needs to be locked for s-on, for s-off, it doesnt matter

after you s-off'd, it went back to locked
On another note I use 4EXT Recovery. It has been the only recovery, for me, that actually wipes caches correctly and runs the Fix Permissions Correctly. You know that it does because it leaves a log on your sdcard. While any of the CWM that I've used doesn't.
And since you're s-off then don't worry about re-unlocking.

after the shut down, when the phone comes back on, does your battery % drop significantly?

i had same problem when i was on ginger bread and updating the sim to wifi calling enabled sim fixed this problem for me. but i am having this random reboot problem again since i updated to ics. i just do a battery pull if it shuts down by itself else it get stuck in a reboot loop.
Just out of curiosity...do you have fast boot checked on or off in Settings> Power ? Turn the check off and see if issue still happens. Just something to try.

No sound on audio calls

Hi I have a GT-i9300 that worked well over a month, after a hard reset I can do anything but when I'm on a call I have no audio either in or out.
I have checked with skype and viber and the hardware is fine. Also I have tried several firmwares (official and custom) and several modems and I still have the same issue.
I cannot apply my warranty since the phone was purchased overseas, please help me on how to fix this.
I am posting this on android development since it is more likely that some developer know how to solve this, also the thread on Q&A is dead. I apology if this is now the correct forum to post it.
Please help me to get my Galaxy back :crying:

1. Relax, it's a common issue nothing to worry about and it can be easily resolved.
2. I understand that you are panicking but development is not a right place for it. In future you may post in q&a section.
3. Are you rooted and have you played with modems lately?

Thanks for the reply
Right now I'm on the original FW again, but yes, I was rooted and tried at least 8 different modems.
Any suggestion?
Moved to Q/A, questions don't go in the development section.
I had the same symptons after updating stock firmware. Both speaker and earpiece worked fine but not in a cell phone call. You should try and let the connection to the other side last long enough and see if your cellphone modem resets like in my youtube video.
http://www.youtube.com/watch?v=fo46OXWEcX0
If it is like in the video than you're out of luck because with me it was an hardware error. Samsung service center could not repair that, the send it to samsung HQ. After I got it back it stated that a hardware part was replaced under warranty.
Any suggestions apart from above ones?

I saw your pm now.
If you are familiar with rooting... Root again.
And perform full wipe, install latest check rom v4. It is LG8 firmware and comes with modem.
Then share this screenshot:

That should fix your issue. Let us know if you have tried this out and it did not fix the issue.

I just fixed it by installing the latest version of an official software from UK. It started failing like before, but after 5 minutes or so it fixed by itself. Don't know why exactly, and I'd really like an explanation so I can know how this happened exactly, but has been working for over 15 hours with no issues (reboots included).
Of course I don't want to wipe again or try another software at the moment, because I don't want everything to happen again, but if someone can really tell why this happens and why it started working alone this will help a lot to know how to reverse it in case it happens again.
Thanks everyone here

Did you obtain fw trough kies? I got the same problem
I got it from samfirmware.com. however today it stopped working again for no reason... could a simple hard reset damage the hardware??? I think it's silly but I can't come up with another explanation.
Tomorrow I will try the firmware told 3 posts above and post the results. In the meantime I'm trying to find an answer of why it stopped working again...
This is frustrating, I'm located in Costa Rica and Samsung states I can only apply by warranty in Germany... so I guess I'm by myself and all of you guys trying to resolve this

Still the same issue, here is the screenshot after the full wipe and software installation.
Please advise
Hi guys. Has anyone come with a solution to this problem? I'm facing the same issue as the OP.
I was running on stock firmware, then flashed the leaked JB firmware and rooted it again. Then flashed the stock firmware again. Once I did that, I started having this problem.
Any sort of help would be appreciated.
Thanks.

Similar problem. I can solve it by full wipe but when I restore application data with MyBackup Pro or in CWR nandroid backup, I lost sound in call.
It begun after flashing leaked JB ROM, then flashing original ROM via ODIN and now on CM10.
Advice?
Maybe modem problem. Try to flash different modems. http://forum.xda-developers.com/showthread.php?t=1740061

I'm having the EXACT same issue. Everything else works fine. It came out of the blue. Last thing I was running was Omega 13.1 with Siyah Kernel 1.5.3. I've had the phone for about 3 or 4 months, then about 4 days ago it started happening out of the blue. I tried flashing and wiping anything and everything you can imagine, including stock firmware. Sometimes it would work for a few calls, then back to square one. Yesterday I went to a stock firmware, then restored my Omega nandroid and it worked fine until I rebooted. I have no idea what's causing this issue and it's really pissing me off. It seems common with no fix.
I live in the US and this phone is originally from Vodafone UK, bought through Amazon sim-unlocked (real SIM unlocked, not via any app). Samsung UK is asking me for the ROM info I'm on, which I can get by flashing a stock ROM (CSC, Baseband, etc), but they're also asking me for a UK address, which is troubling.
Here's every ICS modem ever for the i9300 (not by me): https://www.wuala.com/UpInTheAir/SGS3/Modems/I9300/ICS/?key=n0KVwtIMZPE8

Have the same problem. Flashed the leaked JB and now then went back to stock ICS (Meteor Ireland) from sammobile.com. Still no luck. I'm flashing every modem I can find but still no audio at all. I had some issues with the JB leak that calls sometimes (more than not) didnt work but then a reset would usually solve it.
Anyone have any ideas what else can be done?
I've read it's hardware failure and that Samsung will fix it. However if you live in a region where the phone isn't sold and you imported it through Amazon, Negri, etc, you need to contact the original seller, because Samsung won't touch it if you send it to them directly.
Have you tried wiping cache and fixing permissions? I've had lots of sound issues on JB, all went away after flashing omega 25, no problems now either on omega 27
Also try flashing the modem again, clear cache/fix perms,

Full wipe will always be an answer. However, restoring application can bring the problem again. If you want to backup the contacts just use the export to usb storage in the settings instead of using backup apps in restoring. Also try to perform fix permission.

Issue occurs even before installing the applications. Seems to be something related to the modem firmware, however each modem behaves differently but with the same issue

Galaxy S2 with CM9 stable "crashes" (black screen)

Hi.
I bought a Galaxy S2 phone in July and installed CM9 nightly (and now CM9 stable) on it.
Sometimes (5 times in August), when I take the phone from the table or from my pocket and try to switch the screen on, I find that the phone does not respond to the "power" button to bring the screen back on (just black screen). The phone is somewhat hot at this moment and I have to remove the battery to switch it on again.
When I switch it on again, the battery has reduced a lot (too much for the time passed since I left the phone over the table) just like if the phone was stuck in a battery-consuming process, not just "crashed".
This happens even if I'm connected to the charger (the battery goes down).
I'm using CM9 stable and thoravukk kernel ... any idea of what's wrong? Should I check a different kernel? Is a known CM9 problem and is not kernel related? Anyone else suffering the same problem?
Have you tried installing after full wipe?

Hi.
I installed cm9-nightly-2012-07-28 after a full wipe (previously to this, I was using samsungs' stock 4.0.4), and I had this problem after the full-wipe install...
I passed from the nightly to the stable without the data wipe, and it's still happening...
I'm starting to think on make small tests. First of all, I was planning to replace thoravukk with siyah, to see if it's a kernel problem, or discard the kernel... but wanted to know if anybody is suffering the same problem.
(A friend of mine also suffers it with CM9 and the Galaxy S1...)
Thanks for answering.

Try a full wipe, wipe cache and delvik and reinstall stable, keep stock CM kernel.
Although you can flash from nightly to stable, its good to do data wipe beforehand since you aren't going to flash anything above stable.

Hi.
I didn't wipe the data because it was just a couple of weeks between the nightly and the stable, very minor changes and seemt that wiping was not needed (and remember that I was having those "crashes" with the nightly, and I did a complete wipe to install it).
I installed thoravukk because the stock kernel does not have BLN support and I need it because SGS2 does not have a notification led and I miss text and whatsapp messages if I can't heard the audible notification ...

So... You are not alone! I've got a I9100 with cm9 too. I've the described error too. Also over the nightlys over the past months it changed a bit to do it while in active use. Loss of 30% or something like at once!

The "suddently battery drop" problem is not only related to the Sleep of Death problem described by the OP. It appears in a lot of situations and in mostly all occations (probably including this one), it's just that the battery isn't callibrated anymore and you'd do a battery callibration to prevent those "suddent losses".
Calibrate your battery ! 3 charge et tout rentre dans l'ordre.

It's been more than a week since I intalled Siyah kernel 4.1rc1 and the problem has not appeared yet.
Let's cross the fingers and wait for a couple of weeks more and I'll confirm that the problem is with CM9-stock-kernel and thoravukk kernel.
Thanks!
I've tried with different versions of Siyah kernel (v4.1.5, v4.0.1) and still got SODs.. Reverted back to stock CM9 kernel and same..
I'm leaving wifi on with "Keep Wi-Fi on during sleep": Only when plugged in.
Strangely, I have found my phone SODed even when plugged in charger (that was only with siyah kernel if i remember right)..
Never suffered it again since I installed Siyah kernel...
