Since there is no specifc forum for teh focus flash I shall post this here.
1. Having issues with my focus flash where its constantly power cylces(shows Samsung boot logo gets to windows phone, shuts off repeats until battery dies)
2. The only way to keep my phone on is to constantly press the power button.if i stop pressing the "slide to power off phone appears and shutsdown anyway" (did this long enough to back up photo/music/contacts)
3. Ive tried removing battery(phone boots up as if on ac charge whenever i put the battery in)/ put on ac with battery/ replacing battery/ hard reset
4. Ive installed nothing new on the phone and the cycling happened after being out all day and phone was down to 5% or under battery life.(I put the phone on the charger and it still cycled. left it thinking maybe since power is so low it will take a lil bit to charge and fix but found it still cycling when i checked later)
5.Even with the phone apart board disconnected from the digitizer. Inserting the battery causes the phoneto boot up/vibrate
6.If anyone has any ideas what might be wrong with the mb of the phone it would be greatly appreciated. I have enough soldering skill to replace parts on small boards if need be.

I have a rooted stock phone that stopped working for no apparent reason (no new ROM flashed, no configuration change). It starts, shows the Samsung logo, and immediately reboots. I tried to put it in download mode, when i hold the 3 keys I see the download logo showing up, but it reboots after a few seconds anyway. after a while it will start looping through the battery charge screen (which shows the battery as empty). I tried 2 different batteries with no change. Any idea how to get something working again?
That almost sounds like some sort of power issue. Have you left it sit turned off until the battery was full?
Yes, I left it overnight and it just keeps flashing the battery screen and then resets. I also have an external charger and used it to charge the battery, so it's not an issue with the battery actually being empty.
Have you been able to get the phone into download mode previously?
Have you have dealt with a boot loop and performed an Odin recovery previously? If not, remember it can take a few tries to get download mode to pop up.
If you can't get Odin to go, you might try flashing with Kies.
I am wondering if your phone met with some kind of disaster when you weren't around (trauma or liquid).

This sounds almost exactly like the problem I had with my Sidekick. In my case, it turned out to be a bad battery and a loose ribbon cable on the motherboard. I'd check those two things.
This happened to me as well, and the three-button method to get into download mode wasn't working. For some odd reason, for me to get into download mode all I have to do is hold down the power button + track pad, and it goes right into download mode... Maybe slightly different model?
Try that - power button + trackpad
Bootloops.
Not a guaranteed fix by any means but for troubleshooting purposes you may want to consider making a USB JIG. It will most definitely help you figure out just how serious the problem is and if it IS software related with a way to get it working again you will need the JIG anyway so its worth a shot. If nothing else you learn a new skill and you're the proud owner of an incredibly useful tool that you can say you made yourself. good luck!
I know this post is kind of old, but it just happened to me last week (same circumstance, a rooted phone, but stock). I ended up just pulling the battery out and pressing the power button a couple times to hopefully drian it and letting it sit for 15 minutes, and then I put the battery back in and it worked again. I now have another rom flashed on it, I hate stock.
I know this forum is ancient, but I'm working on an E-Bay phone with this exact issue. I found the following thread the most useful and informative on the problem:
http://forum.xda-developers.com/showthread.php?t=1996709
Hopefully this helps other.
what i did was hold the power volume and button between the menu n back with the left hand YES HOLD IT UNTILL THE PIT IS UPLOADED. then u can let go then slide in the vattery with the right.while checking off the flash bootloarders on the heimdall with it fixing my phone XD
I had this happen, I dissassembled the phone, and used an alcohol pad to clean the power button area, and manipulated the button a lot, let it dry, reassembled...it still bootlooped.
BELOW IS RISKY BUT WORKED FOR ME
So while the back cover was off (exposing the cicuit board but everything still connected) I inserted the battery and watched it boot loop...during this, I used a flathead screw driver to "short" the power button pins...this let it boot fully, and it has been fine since.
i smacked the phones power button a few times and it worked
Last night I ran my battery down to the point where it said Powering Off or whatever. I charged it all night and nothing. When I plug it in, sometimes it has a red LED in the upper left for a econd or two, then does one vibrate, then becomes completely unresponsive.
I've tried a battery pull and hooking it up that way. Same thing - red LED, one vibrate, then nothing. Some times when it is plugged in, it will show a battery picture with no juice for just a second then it all goes blank again.
I am running AOKP build 4 with Slim Kernel.
HELP!!!!!!!!!
I would try another battery, sounds like the one that you have us showing up as dead even after charging overnight.

Just unplug the phone... pull the battery... put the battery back in and WITHOUT plugging the phone in turn the phone back on (may have to hold the power button for a little while).
Strange plugging in the phone without a battery should bring up the charging screen with a question mark in it I think
So the problem has been remedied, though I would like a little input to better document this problem and solution...
I took the battery out, plugged the phone in, then popped the battery in. Really quickly, I got it to enter the weird screen where it is an exclamation point in a yield sign (I forget what combination of buttons I pushed to get here). It said Volume up to continue or Volume down to do something else. This is where it was fuzzy because I was freaking out about having to buy another phone.
Anyways, I hit the volume button that was supposed to reboot and it went through the boot sequence and showed me charging at 98%. This is strange because it was plugged in all night but non-responsive - not power, no heat, no nothing.
So long story short, if running this ROM/Kernel combo - DO NOT LET THIS THING GO TO 0%!!!
And if anyone can tell me what combo I pressed to enter that screen, it would be very helpful. Thanks guys!
The screen you got to is called Download Mode..
Download Mode - This is a setting in which you will put your phone when using Odin. There are other ways, but most people will reach download mode by powering down, removing the battery, and holding volume down while plugging the factory usb cord into the computer and phone. Odin can only communicate properly with your phone if the phone is in download mode.
For future reference you have to
1. hold volume down + power + home button
2. Per on screen instructions, press volume down to reboot/restart device.
This is a documented problem and one that has been posted about numerous times, glad you figured it out. Also, this will always fix the problem so you should not worry if the phone running this ROM/Kernel combo runs down to 0%.
too bad samsung doesn't have a genius bar.....lol
Hey guys,
So my beloved Nexus S has completely seemed to have kicked the bucket. I'll tell you what happened in as much detail as I can, followed by what I've tried and if any of you guys have any tips, please enlighten me cause as it stands right now, I am at a loss.
I was over at my buddy's place for the game tonight and his place is pretty much a faraday cage where I get absolutely no signal. So upon leaving I noticed that my phone is still displaying zero bars. Nothing unusual. Figured I'll check it again in a minute or two to let it reconnect. 5 minutes pass and still nothing. Rare but I have had this happen before. On the rare occasion that the phone just wasn't able to jump back onto Wind's network, I would either cycle airplane mode on and off or just restart the phone and this would fix it. So I turn airplane mode on but notice that while the signal meter disappears, the plane icon never pops up. At this point I start thinking something is amiss... I try to turn wifi on or off but once again, it doesn't pick up anything.... time to cycle the power. So I hold down the power button, select Power Off on the pop up menu and wait for the phone to shut down. Phone shuts off. Wait a few seconds. Turn phone back on. The Google logo appears for a brief second, then the screen just goes blank and the phone just dies.
The phone is rooted but is running stock Jellybean.
Battery was at least 50% when this happened.
It will not respond to the power button at all.
I've tried pulling the battery as well as using my spare battery.
I've tried holding Vol Up + Power, as well as Vol Up + Vol Down + Power.
I've tried plugging it into the charger. (No response. Doesn't even show as charging).
I've tried plugging it into my laptop. Same thing. Tried pulling the battery while it's plugged in and booting/holding reset. Nothing
Phone is completely bricked.
Edit: Just noticed this but I've had the phone plugged into my laptop while typing this up and the area just above the battery around the SIM card has heated up a bit.
Any suggestions? I seriously don't have the cash for a new phone right now so any help is much appreciated =/.
Most likely the motherboard is toast. Happened to a lot of us after upgraded to JB/CM10.
Bring it back to Wind service centre for repair. Not sure how much you will be paying if out of warranty.
I plugged my phone in last night and when I woke up today it was off. I pulled out the charging cord and held the power button with no effect. Thinking the cord may have slipped partly out and let the phone die, I plugged it back in and was greeted by the battery charging screen, showing full charge. I pressed the power button and the phone went black. On further investigation, it seems my press of the power button didn't have to do with it turning off, as whenever I plug it in it shows the full battery screen for a couple of seconds before turning off again. If I unplug it and plug it back in it just repeats this. I've reseated the battery, I've tried holding volume down and the power button, and nothing's changed the phone's behavior. The phone is completely stock, and never opened beyond the battery and card doors.
It's pretty old and I'm pretty sure I do have an upgrade available, so I'm not too upset if I have to buy a new phone, but I'd like to confirm that it is FUBAR before I go that far, and I'd like to be able to extract my data if possible. Any suggestions would be appreciated.

If you have access to another battery, you could try that, but since you're seeing the full battery symbol I'm guessing that that's not the issue. You can always recover your sdcard data by putting it in a card reader, but the phone's apps, app data, and settings may be more difficult.
Well, turns out the problem was much less serious than I thought: my charging cord has bitten the dust. I'm not sure why I've been seeing the full battery, but when I took it to the AT&T store, the person who helped me plugged it in and it started right up. I just need to get a cable that's not my years-old piece of crap that came with the phone.
Battery dead, not charging, stuck on "low battery screen", bootloops with forceboot
Hello people, this is my very first post on xda, even though I've been lurking around for about a year. The community has helped me a lot, I'd like to thank you all for that.
Back on topic though! My error seems to be very similar to the one here.
I was watching some YouTube, battery sitting on a respectable 85%, when it suddenly shut off. Not the usual "shutting down for low battery" kind of shutting down, it was istantaneous, more like the battery was unplugged from the phone. Which is clearly impossible. I tried to boot it using the power button to no avail. I connected it to the charger, and the "the battery is too low" screen popped up. I left it at that for about 45 minutes, then unplugged from the charger and tried to boot. No success. The battery didn't even charge; the charger should be is fully working.
So I tried leaving it plugged to the charger and force boot the phone via volume down and power button; it attempted to boot, but stopped midway through, bootlooping until I unplug it, at that point it shuts off again.
The loop goes like this: OnePlus white logo (normal when you boot), radioactive kernel loading, reboot and repeat. That happens, again, until I unplug it from the charger. Then it shuts off.
EDIT: If I try to get into bootloader instead (volume up + power), after about 8 seconds of me pressing the buttons the screen just shuts off and doesn't react to any more presses (even while plugged). If I unplug and replug it to the charger, I'm back to square one (low battery, please charge).
PC doesn't recognize it. It makes the "the battery is low" screen pop up, but nothing else.
Here's some phone information in case you need them.
Phone info:
Rom: NucleaRom 1.3 (+ Radioactive kernel which comes with it) got it from here
Xposed modules: Youtube Background Playback, AdAway
Root: Yes
Thanks in advance everyone.
I doubt it would be software related if it does it even when in bootloader. It could be the problem I had with my nexus 7 a few times. I needed to charge it like all day for it to even turn on. Either that or faulty phone/bad battery. I hope it's just dead

Hello there, thanks for taking the time to reply. Yesterday I worked all day to try and make sense of the problem. I could have just bought another phone but I'm fairly attached to this one so I went deep.
I was fairly sure (like you) that it couldn't be a software problem, so I looked at the logic board of the phone; turns out (correct my poor technical wording) the bracket (connector?) for the battery on the logic board was coming off from the motherboard itself (the battery was indeed attached to the bracket, the bracket was just coming off of the board). What I did was just reposition the bracket and pushed it down with a bit of force on the board, then replugged the battery in the newly restored battery plug, and tried my luck. It booted! Back at its original 75%-ish.
My only guess would be that due to a fall the bracket got misplaced, but stayed close enough for it to still make contact and never actually shut down, until yesterday. That was... Quite an interesting ride.
Thanks for replying, it was indeed a "faulty phone", but I just couldn't leave it at that without trying
I'm glad it worked out for ya
Not work at all ...
My phone its show the logo on charging or low charge but its stuck for this for while full battary is empty... When I plagued in charger the same show charging logo with indicator but not charging its suck on that logo to .......then I charged the battary externally then put the battary try to open its show only a (powered by android log ) stuck on this ......I cant go any recovery modes ..fast boot mods...
