[Q] Few problems with my phone

Dropped my phone too many times and now the power button doesn't work. I've been sliding out the keyboard to wake it up.
I tried using the CM9 'volume rocker to wake' feature but it doesn't seem to work most of the time. Specifically it only works when it's plugged in, or there is music/other app running in the background so I'm guessing my phone is sleeping too deeply to recognize it? is there a way to make it always work?
I've also had a few other deep sleep problems. Once in awhile my phone won't wake back up. After a night's sleep, I've had my phone freeze once the alarm activates (screen turns on and capacitive lights turn on but screen doesn't work and nothing helps except battery pull), this has also happened when I haven't used my phone in a little while and I get a phone call. Has anyone had this problem? It's especially horrible with my power button problem since I have no way to turn the phone back on after a battery pull without a charger on hand.
Finally, is there an easy way to fix the power button or should I just take it to Sprint?

Try reverting back to a stock rom or at least one based on stock and see if that works. If it doesn't then probably it's a hardware problem.

i can't get it into download mode to do anything (was originally going to revert to stock and take it to sprint). with the power button broken, i had to try adb reboot download and also reboot download with su from terminal emulator. both failed and just ended up doing a normal reboot...
anyone know how i can get into download mode to downgrade?

Use cwm to flash stock deodexed (using adb reboot recovery and the home button to select.

for some reason the stock deodexed fc09 failed to install in TWRP. tried redownloading, no luck. can't find anythign about it in the thread, any ideas?
still can't get it into download mode either, and now i can't even turn it on despite having a charger. it just turns green and i haven't found any combinations that will turn it on.

Remove battery and sd card hit the power button a few times to make sure it is fully discharged. Plug into computer with battery out and try to get into download mode. Also make sure you are using a BB cable and not the stock one.

luckily I took it to sprint and they fixed it for free even though it was on CM...

[HELP] Battery Dead, Boot problems...

Accidentally allowed the battery to drain too low... At first the device would boot up just fine and would get to the OS then shut off. So I downloaded the updated FFF 1.4A.zip flashable bootloader, placed it on the device and was about to install it, in hopes of alleviating this issue, but the device shut off after the file transfer, before I could flash it, and now it will not turn back on.
I'm running this bootloader - http://forum.xda-developers.com/showthread.php?t=1615093 ...
As I said, it won't even turn on (no green light) when I push the button at this point.
When I plug it into the USB cable and/or the wall-charger, the "FIREFIREFIRE Extended Bootloader" screen and the green light just flashes over and over...
Any ideas?

If I could just get it to STOP FLASHING the bootloader screen and get into recovery I have "fff-u-boot_v1.4a.zip" waiting to be flashed...
I had put that file on the device to fix this problem but it shut off on me right after the transfer and it has been flashing the bootloader screen since then...
All I need is to get into recovery!!!!! ARGH!!

I have read from the experts, that you should plug it in, hold the power button down for at least 10 seconds (this makes sure it is off) and let it charge for a couple of hours.

Yea... I've tried that... However, no matter what I plug it into, USB cable or stock "wall-charger", the bootloader screen just flashes. The power button is unresponsive during this. Holding it down does nothing...

I'm hoping to avoid having to do this - http://forum.xda-developers.com/showthread.php?t=1806620&highlight=battery+dead
But I'm preparing for this last resort as it's becoming increasingly clear that this may be necessary.
Anyone have any other ideas?

Problem solved, new bootloader installed!
For some strange reason the bootloader screen stopped flashing after I decided to try plugging it into the stock wall charger again. It stopped flashing and allowed me to access recovery. I unplugged it and it stayed on long enough for me to install the new bootloader...
All is now good. What is strange however is the bootloader didn't stop the boot process. She booted up right into the OS and stayed on. I plugged it in, navigated to Settings > Battery and it is charging!
VERY WEIRD but very cool!
So for those of you having issues with charging, it's absolutely necessary to have FFF 1.4A bootloader installed! If you cannot get into recovery or the device will not turn on, just keep trying the stock wall charger. Just plug it in and keep plugging it in. Keep on messing with it. Eventually, somehow, it will take enough of a charge to get you into recovery...

[Q] Charging Bootloop

When I plug my phone into my a charger and it is charging my phone gets stuck into a bootloop where I can't turn it off nor turn it on. It wont even go to the Samsung logo, it just is black and keeps turning on/off. Only way I have to get around this is by unplugging, pulling battery, reboot recovery, plug back in, then I can reboot to system. Any ideas on a solution to this?

Don't try to power it on while plugged in. Ain't much else to suggest there. I find doing the button combo for download mode then pressing vol-dn at the warning screen works too. This is the normal it's not a bootloop. The way these charge w/ the power off is strange.

What recovery and rom are you using? This is not a normal behavior. It doesn't happen on my phone using Stock rom/TWRP recovery.

That's weird as I'm on my 5th s3 since 6-21 and this has been normal behavior on every one regardless of rom. The S2 did the same stupid shiit. Its almost impossible to turn these on while plugged in and shut off.

I usually use freeg3 from Clark, but I flash about every ROM when they are updated to try it out; I use TWRP to flash them all. My phone is infected with anthrax, but It was before and after it. I even tried flashing the stock .tar from odin :/

When the screen is black, simply hold the power button in until you see the Samsung logo.

I just confirmed again that my phone doesn't do that. With the phone on, I plugged into the charger. Power off, wait until the green battery icon appears. Hold power button, phone boots normally.
I'd guess somewhere along the way you acquired a wonky bootloader. You could probably try just replacing the bootloader, I know there is a way to do that but I'm not sure how. Probably someone else could quote the procedure off the top of their head. If not, I would guess a full odin to stock would fix it also.

My phone does this too. Sometimes it shows a charging battery, sometimes it vibrates, and sometimes I even see the Samsung logo, but it always refuses to turn on while it is plugged up.

My phone doesn't do this. It looks to be a hit or miss on if your phone will do it.
Generating random authentication keys

Or it could have to do with a particular flash that has corrupted the boot loader. People need to be clear what roms they are on, and if they have ever tried to go back to FULL stock through Odin to fix this. Until they have reflashed the Stock Bootloader, there is no way to know what's going on.

[Q] Brick? (Phone won't stay in download mode)

Hey guys, I'm not sure if my phone is dead. It was running fine this morning, Task & Ktoonsez' AOKP with Ktoonsez kernel. However, I tried to unlock it a little while ago and it wouldn't go on. It boots to the splash screen, both normally and going into recovery, but it doesn't last long enough to go into recovery or boot normally. I try to boot into download mode and it boots, but the phone turns off after a few seconds.
I tried to flash back to stock in Odin, but the phone doesn't stay in download mode long enough for the flash to finish.
I'm not sure what to do. Any help would be appreciated.

Pretty sure if it was bricked it wouldn't boot into download mode at all. It sounds like it is losing power or something. The only thing I can think of is maybe your battery is bad. Download mode can run off of USB power if you remove the battery after booting into it. Maybe plug your phone in and boot into download mode, then take your battery out before it shuts off and see if it stays on.

No dice. It just did the same thing it's been doing. I went into download, popped the battery, it stayed in download for a few seconds, and then powered off.
Could it be a faulty power button? The phone is constantly vibrating by itself and if the power button was messed up it could be causing the phone to leave download mode.

As far as I can tell pressing or holding the power button in download mode will only restart it, but won't shut it off. Also it takes about 10 seconds. I don't think it's your power button.

Ah, okay.
In that case, though, I have no clue what's causing the problem here. At this point the only thing I can do is enter download mode for a few seconds, but I can't get it to be enough time to flash a ROM in Odin.

Might be a dumb question... Is your battery charged? I'd plug it in for a while off and see if the battery logo comes up and than try putting it in recovery or download.

I tried that too. It's been plugged in for a while and the same thing happens. It just stays in download mode for a few seconds and then turns off. Also, I tried flashing back to stock in Odin but it failed because the phone turned off before the flash could finish. Now the phone says "Firmware upgrade encountered an issue. Please select Recovery mode in Kies and try again."
So it's basically stuck in download mode cause of a corrupted flash. If I could get the phone to stay in download mode, I could flash it back to stock with Odin, but it's not giving me enough time at this point.

I'm running into the same problem currently, I was wondering if you were able to find a solution. Same ROM same Kernel. I've been using my current version of the ROM since October and haven't flashed anything recently, It just died on me last nigth and now I'm experiencing what you are as well. I was able to turn on the phone somehow last night but it stayed on for couple of mins and turned off again. At the time I had 60% charge.
Thanks

Unfortunately not. Sent my phone back to AT&T and they honored the warranty (despite it being very clear that I was rooted and on custom software).

Thanks. I got the phone when it launched so it's been over a year hence I'm well over the one year manufacturer warranty. Doubt they'll honor it for me =/.

Bad news, It's not about software, it's a hardware issue.
I had that issue with a Sprint S3,
The power button switch is stuck pressed all the time, you can try to hit it a little and maybe it pops out but the issue is gonna still there.
If you remove and insert the battery does it vibrates and tries to turn on without pressing the power button?

yup I just realized it was the power button issue. I managed to fix the problem[kind of], i kept trying to get into download mode while connected to AC Adapter with official charging cables. And it stayed in download mode long enough for me to go back to stock ROM. I'm just trying to avoid hitting the power button as much as possible because every time I do something goes crazy and phone turns off.
I'm gonna try and go to AT&T store tomorrow to see if they can do anything about this.
Thanks again for your help. I really appreciate it.

You're welcome. Good luck dude :thumbup:

I have the same problem. I've tried to install quickly the twrp. But is not time enough

My problem was the battery. After charge a lot, all thing works fine.

Need to fix a completely wiped phone

I just wiped my phone with TWRP using the "advanced" settings and ticked everything. Obviously not a good idea as I think I have wiped everything including the ROM from my phone. Any idea how to get it going again? It just goes to the "Sony Xperia" screen and stays there when booting. I'm not sure how to get back into TWRP (i used to get there from a utilities app that restarted the phone into recovery). I have TWRP backup on my computer before I did the stupid thing...
Thanks for any help!

I've tried to flash from Emma and and Xperia Companion but I can't enter Flashmode (hold the volume down button and connect to computer). It just automatically turns on and shows the Sony/Xperia screen and the LED is solid RED.
I let it run down over night and still unable to enter Flashmode.
I assume TWRP is still there as it was the program that wiped the phone. Any ideas how I can get into TWRP?
The computer does not recognise the phone either. It was rooted and had an unlocked bootloader before it happened.
Thanks!

Hold power down and press power button. Release power button when phone vibrates but keep holding vol down until you see twrp logo. If you don't see it after maybe 10 seconds. If nothing happens you can try pressing power button and when you see led light keep pressing or holding (try both) vol down. If that doesn't work then you can try flashing with flashtool. You can check my thread for downloads and instructions

In sim card slot there is a small red button. Hold it down with toothpick or paper clip until you feel three vibrations. That will shut off your phone.
Now you can try Flashtool or Emma.

Thanks so far ... here is an update.
After letting it run down overnight it eventually let me get it into flashmode. Xperia Companion doesn't work (unlocked) but Emma is trying to work. It has taken a few hours to download the software as the phone only stays in flashmode for about 30 seconds but it was able to eventually download the software. Now it is trying to load it but it gets to 11% and the phone goes out of flashmode (but automatically re enters it without me doing anything) and the cycle continues. Is there any way to force it to stay in flashmode?
I've tried the suggestions above to get to TWRP but nothing seems to work.

I can think of 2 reasons. Either emma is broken (never used it, can't tell) or your connection to pc gets interrupted by bad cable or broken connector. Why don't you try flashtool instead of emma?

I wiped whole storage few times as he did (Without letting it run overnight tho) and you can't charge your battery without system or recovery. If your battery drains in this situation you are SOL

yeah I think that is my problem. The phone won't charge and that's why it only stays on for 30 seconds before losing connection.

Can I charge the battery out of the phone? I know it a pain to pull out ... but I've done it before as it needs changing every 12 mths or so.

Not sure about that. I mean there has to be a way to charge it outside phone but you would need special equipment since you can't just use random charger. Since you said you charged your batteries before you could try to use one of them and hope that they have charge in them for flashing. I saw that @munjeni has a lot of experience with this phones hardware so you could try and contact him and ask if he knows about contact points on motherboard for charging

Ok. Got it going again eventually. Not sure exactly what I did that made it work but FYI these are the things that I did that seemed to help:
Charged it on my ASUS tablet charger today - seemed to do a better job than the other charger I was using (it was a Nokia). It seems to hold a very small charge but was not charging the battery properly. Hooked it up to Emma which had already managed to download the software and put the phone under my laptop (trying to warm the battery to squeeze everything our of it). 355 seconds later it had copied the software and the phone was able to turn on normally again. The phone was getting to about 60% of the software copied across before I used the ASUS charger and the heating the phone technique.
BTW I couldn't get flashtool to work. It recognised the phone but stopped saying USB debugging was off.
Thanks for everyones help!!
