Phone will not turn on [UPDATE]

I rooted the first day and also did lag fix. Worked fine until this afternoon I haven't installed anything today and the only root app on the phone was (besides SU, BusyBox, etc) Root Explorer. Suddenly today while trying to update Twitter and Facebook via the Samsung Feeds widget I get a "network communication error". So I pull the battery and turn the phone back on and I get a very long Verizon splash screen and then it goes black. The capacative keys will light up and blink when you touch them but no other phone action besides that.
Any idea for a fix before I have to go get a replacement? Tried to run the unlagfix batch file and of course I get permissions denied since I can't SU from the phone.
Guess I got a little excited before trying the basics, here's what I did to fix it in case anyone else has the same problem...
1. Wait for the boot animation to stop and get to the black screen
2. Connect USB to PC
3. Run cmd.exe
4. cd to your Android SDK tools directory
5. Run "adb reboot recovery"
6. Once the recovery menu comes up volume button down to "restore factory settings" and hit the home button
7. Volume down to "clear cache" and hit the home button
8. Reboot phone

Something similar happened to me on a BB and also on my original Droid.
What worked: Put it on the charger. Walk away, watch a ball game, or a movie and a half, get some food, think about something else for about four hours.
Come back and try again.
It's a weird thing with these devices. As near as I can figure, they can actually run the battery down faster than the OS/firmware realizes, and then they need a good bit of charge to get running again. In all of my own cases, running off of AC didn't help, either, which really freaked me out.
If it's still not working by morning, start thinking about taking it in.
Good luck!

Updated, got it working.

Awww Right!

Next time, what you may be able to do is run adb logcat to view the realtime log from the phone to get an idea of what's going on.
It's also good to remember that the rage*.bin file that you put into /data/local/tmp is an exploit that should get you root access back temporarily.
Of course, the steps you outlined above are also very helpful. Thanks!

[Q] Nexus S 1st day and its froze, cant unlock

Hi guys, having a problem with the nexus s that i have just got today.
Installed an app for getting wallpapers, something like FLickir HD wallpapers or something.
Set a wall paper, then browsed on through others.
Phone soft rebooted, and now the screen and bottom buttons are totally unresponsive. No idea why, and no matter how many times i battery pull etc i cant get it sorted.
Any help would be a great help.

Can you get into recovery mode?
Pull battery. Wait 30 seconds. Put battery back in.
Press and hold volume up button, then press hold power on button.
Phone should enter Fastboot mode.
Use volume keys to highlight the recovery option.
Use power button to select it.
Once the phone starts to reboot you'll quickly see a little box pouring an arrow into an android figure, hold the power button, then press hold the volume up key. Timing (on my phone) is important, you need to be holding the power key first, then get the volume up key while the box and arrow are still there.
If you get to the Android and triangle, you might still be able to do the two buttons to get into recovery, but it doesn't work on my phone; some reports on various blogs say it does, though.
Once in Recovery, you should be able to pick the option to factory wipe/reset the phone. This will wipe the ROM space and reset the phone, but it won't touch the sdcard stuff. You'll have to set up the phone again, but that's not too difficult.

Just trying it now. Didnt realise about the 2nd stage of the power button and volume up. Just rebooting now after the reset.
Seems to have worked with the phone setup.
Will all my apps be gone?

Yes, all apps from the Market will be gone.
So will your wifi settings, user accounts, EVERYTHING, except the sdcard contents.
You're basically putting the non-sdcard part of the phone back into the same state it was in when you took the phone new out of the box.
I'd recommend appbrain.com for your phone to have an easy way to reinstall apps if something like this has to be done in the future.

last i remembered Backup is on by default meaning all his apps will be re downloaded automagically and the WiFi settings will also be synced

Ah, so much the better! It should just sync up after logging in with his account.
I thought I had to acknowledge I want that feature when I first set up the phone.
Either way, Appbrain still a neat combo of website discovery and phone installation, I find it very useful.

Ive been using app brain and the apps are being re installd.
However some of them that are in my list on the webpage, are not showing up in the app on my device. Any ideas why?

No, not sure, but if they're on your webpage, just click onto their links for the full app description page, then and cancel install if it's there as an option, and then install again.

this happend to me with two phones
Last night after my phone froze after downloading a wallpaper, after an initial pull of the battery the phone booted but the screen was unresponsive to touch, after I tried a hard reboot, with no success, I took it to best buy today and got a replacement. (Phone 1)
I Did system updated asked by the OS after i turned the phone on. (Downloaded update via wifi, and no sym card was in the phone) After Boot it was unresponsive to touch just like the last one. (Phone 2)
I went to Best Buy again and got a 3rd Nexus S. Have not done the system update and the phone is working well....for now
Any thoughts??????

[Q] MT4G won't sleep with Sense

Hi
I have a rooted stock ROM/Theme MT4G which I noticed last week that it stopped going to sleep. If I set the timeout to 15 seconds (or anything) then right after the timeout is reached the screen sleeps and then within a second immediately comes back on (to the lock screen). It keeps doing that no matter what settings I try. This of course kills the battery life with my screen being nearly 100% of use.
I thought it was related to an app update so I removed nearly everything I could to no avail. Thinking that it was something related to the ROM I decided to try a different ROM. I installed CM7RC2 and low and behold the same problem persisted. I had to disable trackball wake for this problem to go away. I then tried several other ROMs and the problem still remained. I've attempted the various Royal* ROMs and the same problem persisted. Any Sense based ROM was problematic since I had no way of disabling Trackball Wake so I'm now running CM7 (nighties).
The other snag I'm having is that I too have the problematic power button but in my case I have to REALLY press hard to operate the power button which of course is annoying.
Anyone have any suggestions or experience with this sort of problem?
Thanks.

Did you check out the Cyanogen mod 7 in settings ?

I did. That's what I'm running now.what exactly are you suggesting? Thanks.

I have the same exact issue, ive been trying to get some devs to add the disable trackpad wake option in sense roms but so far nothing so right now i use either royalginger or royalmiui im on miui but i really miss sense :/

I had the same thing. I booted into recovery and wiped data and cache and flashed again and everything worked.

I must have done that a bunch of times already but nothing worked except CM7 because I can disable the trackpad wake function. I wish Sense based ROMs allows for disabling the trackpad...that would be greatly appreciated. An even more helpful feature is the ability to remap the buttons.

Is it possible your trackpad is defective? DO you notice other odd behavior that could be related to it?

If your using google voice its the application doing that you can fix this on cm 7 by moving the application to the Sd card.

I believe this is a real hardware issue... It seemed that the optical sensor in the trackpad is broken and it's always sending signal to the kernel telling that it detected activity but in reality nothing was going on, so the kernel can never go into power saving mode.
Sense UI is a CLOSED SOURCE software, there's nothing you can do to patch it.
Since ALL MT4G are still under the 1 year Manufacturer's warranty, you should call T-Mobile/HTC to get it fixed or just get a replacement....

Ok I found a solution for us mt4g owners with the messed up trackpads, you are gonna have to flash virtuous unity rom v. 2.39 and then apply this patch:
http://dl.dropbox.com/u/28766802/Virtuous/trackpad_disabled.zip
This patch was made by one of the developers of the rom chrisch1974 specially for this issue, so good luck =D

Same problem, but found work-around
My phone (MT4G) has the same issue but I know why it happened. I got caught in the rain and although I had the phone in my pocket, it got wet. Everything works except that. I left in a bag of rice overnight to no avail.
Anyway, when I press the power button to send it to sleep mode, it just comes back to the lock screen. If I let it time out, it goes out but comes right back to the lock screen. Sounds familiar?
What works for me is holding the home button (the one with the sensor) and, while still holding the home button, pressing the power button once. It is then that I let go of the home button.
Works, but sometimes I have to repeat this charade a couple of times before it sticks. Usually have to repeat it when I don't fully press the home button.
Anyway, hopefully this will help someone that is stuck with this phone and is unable to get a replacement.

Sprint LG G2 - Lock screen not activating, Home soft key not working...

This just started occuring this afternoon before and after I installed the latest ZVA firmware:
1. The "Home" soft button responds to my touch - as in I get the visual and haptic feedback as if I've touched the soft button but it refuses to actually DO anything. I can hit the Home button on any screen and any app and it takes me nowhere.
2. The Lock screen is no longer activating - as in I let the screen hit the timeout and let it set for a few minutes. If I try to "knock" on or use the power button, it opens right back up where I left it with no Lock screen.
I hope this makes sense. I'm really stumped here. Like I said, it just started happening this afternoon and I figured that it was some weirdness to due w/ the pending OTA update. After installing the OTA update, the problems persist.
I'd rather not do a factory reset, but I will if I must

Bringing this old post up as I just now encountered this on my AT&T LG G2. It occurred when I was using Google Maps which then crashed and caused everything to freeze. Upon reboot, I get the exact same issues as stated above. What was the outcome for you guys? Did you end up doing a hard reset?
Everything appears to be functioning with the exception of above. I'm suspecting a software issue with the home launcher as the soft keys are responsive but the Home one. The Notification Bar lags when trying to drag it down, but none of the notifications are functioning. I also noticed a significant amount of lag. Prior to the "crash" my phone was flawless with no lag for the past 10 months. I absolutely have no clue what just happened...

weird phone reboot?

so last night my phone randomly froze and rebooted into the command page with the little android guy saying no command. So I had to reboot system and all is well. anyone have this happen to them?

That sounds like you booted into recovery mode. Not sure if this can be done with a button combo or not. If you were able to boot fine, it should be nothing to worry about.
I believe once you see "no command" you can hold power button and tap VOL UP then release both buttons and you will see some options, one of them being reboot, which will go back into normal Android.

Yeah it was recovery mode and it did it all by itself which was weird but no its fine and I got the security update seems even smoother if that was possible

This just happened to my phone at the beginning of a phone call! I didn't know what to do, so I just held the power button down a for a few long presses and fortunately it rebooted. Seems OK now, but leaves me a little worried!
