[Q] Galaxy S II - Keeps turning Off - Galaxy S II Q&A, Help & Troubleshooting

Hello,
I'm kinda new here and am having issues with my S II.
It keeps turning of sporadically, but doesn't reboot then.
It then stays off, needing to be turned on then again.
Do you guys have any hints or tips?

Hint: at least you dont have a bootloop.
Tip: next time post details about the phone and firmware and when this happens/what you were doing etc.

it was in standby mode
Here the details:
Android: 4.1.2
Baseband: I9100XXLPX
Kernel: Siya-Dorimanx V7.8
Build: Resurrection Remix JB: 3.1.2

It might be the battery. Do you still have a warranty?

Try clean contact between battery and phone.
My friend had same problem, new battery fix it.

I see you are using siyha kernel are you undervolting or underclocking your rom if so reset the values

[Q] What Kernel do I Use

Hi People I have a Problem that should be easy to solve for most of you ^^.
I have a rootet Galaxy S2 with the following rom on it:
.galaxys2root.com/galaxy-s2-roms/darky-ics-rom-for-rooted-galaxy-s2-gt-i9100-xxlpqofficial-ota/
My Device is running
Android Version: 4.0.3 (Official Samsung Firmware)
BaseBand: I9100xxlph
Kernel: 3.0.15-I9100xxlph-cl118559 [email protected] #3
build: lidroid-resurrection remix ics 9.6 by westcripro.build.version.incremental=xxlph
everything is working fine execpt the batterylife.
in my opinion the last rom (stock) was way better.
so my question is: is there any kernel that matches the rom i am actually using that increases the batterylife ?
at "normal" use my batt is loosing power very fast.
-no gps on
-display turned down
-wifi is not running
i am very new to those things. its my first xp with rooting and modding.
help would be nice.
Chainfire has a CF-root for LPQ. Maybe try that and have a mess about with the voltages?

Acording to your device info your on LPH and thats a BETA firmware.Your battery wont get any better until you are running the official release LPQ firmware which has increased quite a lot the battery life in my opinion.Flash the LPQ firmware and an LPQ based custom ROM.

Galaxy S II - Woes

Hi Guys,
Okay. I am a noob and I hate being a noob, and when I registered for the site I watched the noob video. Whilst I did do my research on xda, androidforums etc. I feel I still need your assistance before I go on to ruin something.
Phone: Galaxy S II
Location: Australia
Network: Vodafone
Kernel: XXKF2
Rom: Litening Rom v1.5 XXKF2
Android Version: 2.3.3
Mode: GT-I9100
Symptons: Low internal storage, drained battery, when charging or in use, can get very warm near the camera lens.
I've actually had a great run with Litening Rom until one day I woke up and my alarm went off for work. I went to turn it off and the battery was so hot I could've started scrambling some eggs. In a state of panic, I turned the switch off and the battery charge for 6hrs was 5% - wtf. Long story short, I've searched and found many threads with many different unofficial responses. I'm to the point where I'm deciding to go back to stock or to another rom. Most of the download links I've searched on XDA seem to be invalid (i.e stock Kernel XXKF2 and Litening Rom v3.2).
In anycase, do I need to:
1. Download specifically the XXKF2 kernel? Or can I try another? If so, can anyone direct me elsewhere as god knows I've tried.
2. Anyway to remove rom on its own? I've got Odin etc.
3. Can I also clarify that when I rooted the phone to the Litening Rom, does that change the stock Kernel? If not, then perhaps I just need to goto point 2 above.
Any assistance would be grateful.
Thank you.
Hey mate.
When you flashed the custom ROM you would of also changed your kernel.
I would suggest trying Siyah kernel, I've used it and I had great battery life.
That should help sort out your other issues too
Good luck!
Youre talking abouth odin and lightning rom so youve rooted and flashed allready......so your a bit noob-off,but as above said try another kernel or better....flash an other rom.
Download some other roms, reboot in recovery, flash them try it for an day....with outh installing your app's , install your app's when youve got an rom of your choice/like's see what the battery drain does and the heat development at the back......try it greatz mike

Answer: Your phone is NOT bricked
It's like your phone wasn't really charging. Remove your battery, re-insert the battery, then charge again.
Let me know if the problem persists.
Also post your ROM and kernel info. Goto Settings -About, and post everything you see

Yesterday
My phone is RR 3.05 Aokp & CM10
Then i flash back to Rootbox 1.8 & CM9
I face apps FC after i restore data from 4.1.1 to 4.0.4
But that time the battery left not much, then i charge my phone 4.0.4 (but the % will not increase)
then i restore nandroid back to RR 3.05 Aokp & CM10 but still not able to charge
This is the case
And just now i took out the battery for 20 min and then i offline charge ( i think it is charging now )
Finally it back to normal ( i guess so far)
I found out because battery drain very fast due to what i done (maybe) So, 8 hour charging only from 1 to 9%... Now my phone charge back 100% (switch it on left 94%) then i reflash rootbox 1.8 ics with a proper procedure again. Battery drain slower and my phone keep aware due to (media)
after i kill some background apps ... Finally my phone can deep sleep and now i am testing the battery drain.
BTW, thank you Jokesy

[Q] Need Assistance for Unresponsive Screen.

Hi All,
Greetings!
I currently have a SHW-M250K galaxy s2 model.
I have flashed it with i9100 gt firmware.
However, some portions of my screen are unresponsive, only to some applications. The lower part of my screen is not being detected properly. Its as if some applications only detect my screen as 4.0 instead of 4.3. It only happens to some applications. Keyboard and other apps seem to work fine.
My details are as follows:
Model: GT - I9100
Baseband: I9100DXLP7
Kernel: 3.0.15 - TH [email protected] #2
Build Number: IML74K DXLP7
Would updating my kernel be of any help?
What would be a good way of fixing? Would wiping all my cache and data help?
Any help would be greatly appreciated.
Thanks!
bump
Hey...
yes, try to update or use another kernel once.
If this won't help, last option is to make a full wipe, but try the kernel first.
If u hadn't the prob before and not bigger drop of phone or anything like this, it wouldn't be a hardware issue
