Nexus S wont turn on after charging.

I'm using a 9020A model purchased on Ebay for 2 weeks now.
twice already within a few days the phone will not turn on in the morning after charging it all night (in stand-by).
It will not turn on even into boot-loader.
if I take out the battery it turns on like nothing happened.
Any idea what the problem is ?

Thats what you called "SOD" screen of death. Just pull your batery when it happen. Also it might be kernel related try changing kernel

I'm running CM7 since day one with whatever kernel it came with.
What other kernel might work with CM7 ?

There are still a couple though i don't think any are in development any more. Since it seems to have only happened once so no need to try out different kernels. I wouldn't worry about it at all unless it becomes a regular occurrence.

This seems to have happened to many others with the stable CM7 rom version.
In another post someone who had the issue reported that switching to Netarchy's kernel addressed the problem for him.
This happened already twice today so looks like I need to find a solution.
How difficult it is to replace just the kernel?

Get ahold of a GB compatible kernel, wipe dalvik cache and flash the kernel .zip file. Do a NANDROID backup beforehand (CWM -> backup) if you don't have a recent one already.

In another post someone suggested the following Kernel:
http://forum.xda-developers.com/showthread.php?t=936219
There are CFS & BFS builds. which one should I use? what is the difference ?
Also the kernels are labeled as "2.3.4+ based roms (Nexus-S AND Sprint Nexus-S 4G Phones)", However the CM7 rom is based on 2.3.7. would that work ?

CFS is a fairer CPU allocation scheduler, and generally better for multitasking as well as overall performance. BFS is, in theory, better at doing only the "task at hand", but so far hasn't proven any better than CFS, and is additionally less stable most of the time. tl;dr, get CFS.
Kernel should work fine on 2.3.7, don't stress about it. In the event that something goes wrong, just make sure you have a backup anyway.

netarchy-nexus 1.4.1 CFS Kernel is labeled "experimental" since october 2011. Is it OK to use it anyway ? how exactly is a kernel flashed ? via recovery ?

Yup, it's OK to use it anyway. Also kernel is flashed via recovery.

Any need to wipe or reset the phone before flashing a new Kernel ?

No need. Simply flash the kernel, via fastboot

flashed the kernel via recovery. I'll report back if the SOD problem is resolved.

5 days later and not even a single "SOD" freeze. looks like changing the stock kernel
did the trick.

3 weeks after flashing the Kernel and the SOD problem is back. 3 times in last 2 days.
Anything I can tweak to avoid these freezes ?

Most stable custom ROM with kernel?

Hi all. I am a proud owner of a 32gb wifi Nexus 7. While not new to Android, this is my 1st tablet. Love the size, weight and most of all...is android!
My question is, what combination of ROM with kernel would be best? I know there are a lot of things to consider, but I am looking for opinions only. Without talking down certain ROMs and/or kernels, we can share here opinions based on stability, customization and smoothness! I already encounter an issue when I rooted my 2 days brand new N7 rooting it with the Tool kit. Rooted it fast and easy (successfully), but installed TWRP. Me knowing no better, I love and I'm used to CWM, so I installed ROM Manager and CWM. Long story short, when I went to flash one ROM in particular, in recovery, when I formated system, data reset, wiped cache & dalvik, it wiped my sdcard clean. I mean, thats how I flash my Note 2 for a clean install and never had an issue like that. Then, when I tried to get into recovery via fastboot, I couldn't. It was like CWM wasn't there.
Thanks to the Tool Kit, I was able to un root and go back to stock....then rooted again (with TWRP) and finally flashed CM-10 stable. Also flashed faux's 4.1.2 kernel @ 1600. I like what I have so far, but I would like something more. I got the stable CM-10 from the actual CM thread so the ROM is pretty much untouched.
Can anybody please share what ROM and kernel I should try for a bit of stability, power and smothness at the same time? Any inputs and/or advice, will be greatly appreciated!

Try Paranoidandroid as a ROM. And i think the kernel that comes with it is the smoothest i have used with it.

Hi, Wally72...
I don't know if this question can be answered objectively... it all hinges on how you intend to use the device, day to day. If your going to be playing high-octane video games, then a kernel that supports overclocking would be advised... but that will come at a battery life cost. More CPU cycles = battery drain.
For myself, I am currently running PaulOBriens MoDaCo custom ROM (can't post links yet, but Google MoDaCo Nexus7, and you should find it)...
The standard MoDaCo ROM for the N7 doesn't go too far off stock... it just adds some really nice features... AOSP browser (better than Chrome IMHO), expanded powerdown menu, Adobe Flash Player in /system (although Adobe no longer support it, it's still useful to have).
Paul has recently ventured into CyanogenMod territory with CM10.1 unofficial nightlies... which he has stated will be released every Friday.
And this is what I'm running now - MoDaCo CyanogenMod Custom ROM r3 - and in conjunction with Franco's r39 kernel, it's incredibly smooth... and very respectible battery performance as well.
Hope this is of some use...
Rgrds,
Ged.

[Q] Any Problems with this setup?

Hi!
I have a Samsung Galaxy S4, rooted and I'm loving it!! Butter smooth but still few few few microstutters or a bit lag here and there, but a HUGE improvements from the Stock kernel and ROM. I Will maybe flash new to the new Google kernel for S4 GT-i9505 once It is stable with more updates.
My config is;
Adam Kernel v1.5 for GT-i9505
Omega V9 Custom ROM for GT-i9505
and last but not least the latest Crossbreed 7.2... something I don't remember.
Is there any problems running this setup?
I managed to install everything on TWRP 2.6.0.0 Recovery without any sweat. I have ran this setup for almost 2 days now...
And my question is could the custom stuff that I have on my phone brick or be damaged? Or is it completely safe to run this 24/7 without any damage on the android device or problems in the future?

As long as all is compatible and they don`t interfere there shouldn`t be a problem. If you have spontanious reboots and/or FC`s you`re in trouble

Okay thanks for your reply ).

[Q] Android Kernal, what is it?

I'm using a Galaxy Note 3. I've flashed it with a ROM called X-Note which was really great! And it had 3 options for custom kernals to use. I can't remember which one I chose, all I remember is the other two seemed to prevent my phone from booting. (maybe the issue, I'm no expert).
And now I have recently flashed CM11 via temasek's build and it's working very well indeed. The thing is though, they seem to have their own kernal that I can use. I'm not though, I'm just wondering what it is and if I should try using it.
From my experience some kernals can stop the phone from booting. Is this true? Maybe it was just coincidence for me? Can anyone explain?

(as a side question, X-Note also came with a custom version of TWRP. I'm thinking of going back to Clockworkmod recovery as there's a few new ones on the GN3 XDA threads. What would be the easiest and cleanest way to do this?)

temasek's kernel is very good and yes flash it great for battery

Screen discoloration and weird zoom after trying to flash CM-11

Hi all,
Today has been a disastrous day for me. My Nexus 4 decided to update itself and got stuck at "Android is updating.... Starting apps.." screen. It is rooted and the bootloader is unlocked. Fastboot recognized my phone but not adb and I couldn't figure my way out of that so I basically reset my phone, flashing the stock version of Android 4.4.2.
It worked fine for a few minutes, so I tried flashing the latest snapshot version of CM-11, but that failed. I believe it was after I restarted my phone that everything became discoloured and the screen was zoomed in and repeated.
I tried flashing the stock ROM again in hopes of fixing the discolouration and zooming, but it didn't help. I've attached a picture of what my phone's display looks like. The colours of the bootloader are normal and unaffected.
Can anybody help me with this? I've been using Android Toolkit 1.2.8 and Nexus Root Toolkit on my Windows 8.1 x64 laptop. My Nexus 4 currently has the stock version of Android 4.4.2.
I'm inexperienced at this, so please let me know if more information is required.

you are using a kernel that support AOSP rom with a CM11, you should use a compatible kernel

Thanks for the fast response,
Sorry, could you be more specific? I not QUITE sure what that means, but could it not be an issue if I've flashed the stock 4.4.2 onto my phone?

Thank YOU!
I guess I kind of remember flashing the stock 4.4.2 failed (I think it said too many connections), but I retried it just now after restarting my computer and the display is back to normal.
In terms of kernels, how will I know which kernel(s) is/are compatible?

if you are using cm11 or any rom based on cm11 you should use a compatible kernel, if you are using stock/aosp rom you can use almost all kernels like franco.kernel, ak, hellscore
