[Q] Xperia play having problems starting

So my Xperia Play (CDMA) has been fine until earlier today, i had the phone on, but then when i try to wake the device, it won't wake, but the device is still on cause cause some buttons cause vibration and the back light is on, just nothing on the screen.
so i go to reboot the device, now i can't even get it turn on. i hold down the power button and it briefly starts up (no boot screen) then the led flashes green/pink/blue then stops trying, back light stays on. i keep trying still same thing. can't even get it into fastboot mode. the battery is fully charged (plugged it into a charger.) and I was last using fxp cm9 rom with lupus kernel.
after repeatedly unplugging device, removing battery, i got it to display the battery charging screen. but when trying to get out of that screen i get the whole not turning on thing again. and i should say i can tell the back light is on.
once in a while it will connect to the computer and then i can access the logcat, which is right here: http://pastebin.com/FiJFrEGE
the only thing that causes entries to write to the log is by opening/closing the touchpad.
I am very confused what the whole green/pink/blue led light is about, and why this issue is happening, is it kernel related, rom related, or hardware related, i have no idea. i'd appreciate any help i can get on this or if anyone else has had this issue. thanks.

Try flashing a stock FTF from flashtool. Might make things go back to normal.....

When I was using CM9 I use the included FXP kernel, so maybe thats why you're having a problem. Or perhaps the Lupus kernel you flashed was a GB build opposed to ICS.
Flash stock FTF an re try.

Thanks for the replies, I'll try to install a stock ftf. Also I do know which lupus kernel is which at the moment I'm running the cm10 blend with jb lupus kernel since i got the device to boot after x tries.

[Q] Samsung Note N7100 stuck boot loop when unplug,but when charging loads the KitKat

Hi Guys,
've flash my Samsung Galaxy Note 2 N7100 to 4.4.2 KitKat it was successful, but after a few days my note 2 keeps auto shutting down randomly and sometimes I can't turn it on from sleep. I thought I've just missed something when flashing to 4.4.2 KitKat, what I did was to re-flash it and check if I've missed something but not. After I re-flash it, I've encountered this problem. I'm stuck at boot loop, I've done the Wipe process it was successful, but it didn't fix the problem, what I've noticed is when it's NOT charging or plug to PC it is stuck at boot loop, but when I plugged it to PC or charge it it continues loading the KitKat, sometimes prompting that it's not charging.
I'm wondering what could be the problem here. I've google any possible problem, I can't find any similar problem to mine. Can anyone help?
I'm still try any possible way to fix... HELP!

I exactly encounter the same issue on my Note II. It seems that the automatic reboot (then the boot loop) when the phone is unplugged is generated with apps (or system) using internet connection or the camera.
Please help ! :crying:

I had a similar problem with my note 2 N7100.
It used to reboot every 30 minutes.
The best solution was to reinstall the firmware using ODIN.
First you need to download the firmware from sammobile and put the phone in download mode and install it.
Hope this solution helps you too.

Thank you anish. I already tried this solution (with stock firmware and Cyanogenmod 10.3 &11) but it didn't work for me
The phone boot only happens when I unplug the USB cable and launch an app. If I do nothing after unplugging the cable the phone don't boot immediatly.

Hi guys ! I finally found a temporary work around to avoid automatic reboot. After multiple tests I noticed that the issue seems to come from CPU usage.My phone never went to deep sleep and often stayed around 1600MHz.
The work around was to go to Preferences > Performances > Processor/CPU > Strategy select "userspace" . The CPU goes down to 800MHz but I don't have any more automatic reboot when the USB cable is unplugged.
After reboot the boot loop is still there (so I need to put back in the USB cable to boot normally). I was wondering if the boot loop comes from the boot.img file...

Ive literally tried everything .even repartioned the phone . it works fine in recovery and download mode but as soon as i want too boot to android unplugged it restarts . when plugged it has no problem

Funny thing. I have a factory Sprint Note 2 with the latest kitkat updat and I am experiencing the same problem. Phone has not been rooted or messed with. If anybody come across a solution let me know. I booted the phone and unplugged the power button to verify and it does the same thing. Only stays on when in airplane mode or charging.
One more thing. I tried somewhat to do what was posted above about performance / cpu power. I put the phone in powersave mode and checked limit cpu and is is fully operation. problem gone. If I turn power save mode off I'm back to square one.
To late. Took a picture by mistake and phone jumped into boot loop.

i have GT-N7100 and same problem phone is stuck on boot loop when unpluged
---------- Post added at 04:22 PM ---------- Previous post was at 03:24 PM ----------
i just tought maybe it needs new battery. cause before i unpluged it it showed 67% then bootlooped 2x then i pluged back in and it shows me only 5%. i think its battery cause it cant dishcharge in 1 or 2min

My initial problems were that it would drop signal and show an x with no bars intermittently. then i started having problems anytime the phone demanded use. Picture, internet, video. tried a few things listed above. Still would go into a boot loop when not plugged in. Battery would charge normally and show it percentage like normal. It would reach 100% with no difference in charge time. When battery saver is on it would not have a problem unless I use an app that demands more cpu usage, network connection, battery consumption. Put a new battery and problem is gone. some people say the battery show swelling but my battery looks identical to the new one. no swelling and it is not deformed in any way.

It also solves the problem for me ...but i dont know what to do after the restart ...have u found a permenant solution

I was thinking. If you flashed with a bad battery whats there to keep it from affecting the flash / update. The stock system doesn"t allow an update unless the battery is charged. It doesn't know if the battery is faulty. Try to reflash after a new battery has been reinstalled and charged to full. It's just a thought.

Where is the Preferences section? I am unable to find that on my Note 2 settings.

Experienced the same thing and this is the first time I had this. I was playing a game after I fully charged my battery and suddenly it turns off. So I waited for it to turn on where I noticed that it keeps on turning on and off and stuck on the " Samsung Galaxy Note 2" logo screen. Then I tried several things like clearing the cache and dalvik but it just do the same thing. I re-flashed the 4.4 ROM that I was using but sadly it does the same thing. I then noticed that if I plug in the charger it works normally and does not boot loop. And as soon as I remove the charger it will keep on restarting on and off on that screen. I was thinking that it might be a hardware failure or the battery itself. So I went to recovery mode and unplugged the charger, it stays on. Went to download mode without the charger and it stays on. Freakin' weird. I am about to flash a different ROM and will wipe everything and see what happens...

Fully charged the battery to 100%, unplugged the charger and it started to boot loop again. I allowed it to boot loop once and immediately went to recovery mode and saw that my fully charged battery went down to 3%. Tried different ROMS (Omega, DN3, and Phoenix), I still have this issue. Now can use my Note2 as long as the charger is plugged in...

Change your battery and solve the problem ?

It works perfectly !

Phone only stays shows Sony Logo for a second and shut off

Hey guys.
I am having a problem with my phone (C6503) is when I boot up my phone, it will show the Sony logo for a second and shut off again. When I plug my phone into the charger, it will do this in a loop.
This all started when I flashed MIUI v5 from here (I have a locked bootloader, and it can't be unlocked): ( http://forum.xda-developers.com/showthread.php?t=2520793 ) and I was simply using it one time and it was suddenly shutting off on me. The phone would also would also say the battery was at 85% then shut off on me and when I turned it back on, it said it was 5%. It got worse, when I powered on my phone while the charger was in, it would boot up, and when I unplugged the charger, it would shut off. Now, when I power on the phone, it displays the Sony logo for a second, and then shuts off.
Thankfully, I can still access Flashboot and FastBoot mode on the phone when it's plugged into a computer.
At first, I thought it was my ROM that I flashed earlier, so I tried flashing a stock ROM that I came from earlier. I tried a couple of stock ROMs and it didn't work, I also tried flashing stock kernels to it, too, and no change. I'm starting to think that my phone could possibly be dying on me from a hardware prospective instead of a software prospective, and it may not be the ROM I flashed earlier, since I was able to use it earlier before this started to happen.
Any help will be thanked.

I`m having the exact same problem (it started when I flashed the same rom, btw), did you find a way to solve this?

I have this problem too... my xperia is c6504 and I can't find a stock for it, I tried everything.. need help

Sleep/Wake problems [SOLVED]

So i was using Darthstalker v3 and arter97 kernel 9.3 with no issues.
Suddenly one day, i noticed screen flicker when waking the device, followed by hesitation. So my first step was to wipe the dalvik/cache. That apparently did not help.
I then lost my bootup logos, as well as shut down, along with the screen pretty much refusing to come on.
I used smart switch to emergency recover the stock firmware. Nothing. Then i Odined a stock untouched rom. No change. Once i actually got the phone to render the screen in recovery, so i wiped everything three times, and and flashed darthstalker v6. I also rooted the phone again just before that. I
So when the phone is powered off, the battery icon is present, and the screen wakes to that no problem. Since i set the device to never timeout while charging,
when i plug it in, the screen comes on, but as soon as i try to touch it, poof, the rendering of the screen goes. But, while this occurs, i can hear the icons being pressed,
etc. Completely stumped as to what to do. Can someone help?
[SOLVED]
strangely enough, I found a solution in a most peculiar way.
I managed to finally get into the phone by charging to 100 percent. Then, I downloaded flashify, and attempted to flash tekxodus rom, as well as selecting dalvik and cache wipe.
The flash did not work. the phone just rebooted. Then, I downloaded rom manager premium, and then rom manager attempted its prerequisite attempt to detect my recovery. (up until that point, I had twrp installed).
The detection lingered, so I pressed the back key and selected reboot into recovery. Surprisingly enough, I was back in Stock recovery.
So apparently the solution to the anomaly I encountered in the OP, is to either follow the simple steps above, or, to flash stock recovery in Odin. If that is at all possible for the user. I can confirm the above worked for me as I tried everything for the last week and this was the only method that worked.
The shutdown/startup logos are back, with no screen flicker or hesitation on sleep/wake.

yeah i just suddenly started having this problem. my phone would reboot itself and then it would be updating apps as if i just flashed xposed or something, my phone would have issues with wifi, flickering lockscreen, and if you rub the screen while its off which wouldl show you information stream doesnt work either. Decided to dump the rom. Am going with the TEKXodus N5 with arter kernel

It's just like I told you. When I read that you had experienced the same precursors that I came across with the rom, I had a hunch you would be soon after posting the exact issues that I eventually ran into.
So when you download Tekxodus and flash, please keep me informed as to if it resolves the issue. As you are aware, stock firmware has not resolved the problem for me, but then again devices vary.

So enjoy the fix if you ever run into the above issue.

Im fine with stock, but I miss the fun of trying new roms.

Bizzare Issue on HTC

Hi guys
I seem to have an incredibly weird issue on my HTC. It is rooted and running DU 6.0.1.
For some reason, despite the battery being 60%+, whenever I unplug my phone from power it just switches off. If I try to reboot it/go to recovery, it starts up for a second and goes off. However, it seems to function normally when it is plugged in via usb. I can access recovery as well. I have tried to reflash as well as a full wipe, but nothing seems to work.
Im thinking something went wrong with the boot.img maybe ?
Any help would be appreciated.

Maybe its a stupid inquiry but does battery work as it should in stock rom? so that you can be absolutely sure its not faulty battery that's creating issues.because two things happen(in my experience when something goes wrong with boot.img) either its stuck at splash screen (hboot) with red text OR it goes blank but not off, just blank

Definitely isnt the battery. I am not experiencing any drain and it functions completely normally when plugged it. When I unplug, it works fine for a few min and then switches off. It will then not turn on, despite it showing 90%+ when I plug it in

but it happens in stock rom also? thats what i wanted to know .if you can full wipe and phone works when connected to usb,maybe you can run ruu and confirm that as well . If you can go to recovery ,make a nandroid backup.and try a ruu.

Yup, happens on stock as well.
Also, I think the recovery is messed up as well since it just crashes now when trying to flash something. It's having issues doing a nanroid backup as well

And no love for exe ruu as well?
