Bricked Xoom / Black Screen - Xoom Q&A, Help & Troubleshooting

My friend rooted my Xoom with EOS ICS the other week (has done to own and others often), and all was working fine until a few days ago. I was in hospital and put my xoom down so they could take some vitals, and when I picked it back up, the screen was black.
Tapping the power button had no effect, neither did soft reset. When I tried a hard reset the moto dual core logo appeared for about 10 secs then disappeared. Since that moment I have not been able to get a response out of the device. I placed it away for 3 days to allow the battery to discharge, based on another thread, and that has had not effect.
there is no recognition with ADB in cmd, nor does windows detect when attached via USB....
Any suggestions?

you wont get anything thru adb unless it is on. do you get the red moto logo?

Moto G unresponsive

Looking for a quick fix here as I can't go to the service centre and get a replacement until at least Tuesday, and I need my phone working before then. I'm hoping someone else has had the same problem and can help me out.
My Moto G froze and became unresponsive (while I was refreshing my Gmail inbox) and it would not accept any input. I held down the power button and the power menu opened, however when I tried to power it off, it wouldn't accept my touch input. So obviously the next course of action was to hold down the power button for 10 seconds to force a reboot. The Motorola logo appeared and the phone vibrated... then it did nothing.
I tried this a few times and still nothing happened. I am able to boot into the bootloader, but apart from that, the phone goes only so far into the boot cycle before the screen goes black and does nothing.
Motorola's website suggests that if the Moto G becomes unresponsive, and the regular 10 second reset doesn't work, you should hold the power button for 120 seconds and keep it plugged in to a charger. This didn't work either. As of right now, my phone is just sitting here on my desk with what I would call a 'black screen of death.' Help would be appreciated.
I cannot boot into recovery, I cannot access anything. The phone is stock, unrooted, and running KitKat 4.4.2 without any modifications whatsoever. It's about 5 months old now, so it's still covered by warranty and I don't want to void it.

Can you boot into bootloader mode and use adb command from a pc? If yes, maybe you can try to flash a stock recovery img file via your pc to phone.

Would that require unlocking my boot loader though? I don't want to void my warranty, especially considering I did nothing to the phone and it's currently unresponsive.
I am not sure - but my guess is that bootloader needs to be unlocked to install custom recovery to "recover" & backup userdata before flashing the entire original stock firmware; that's usually the first step we see in all those modding guide in different forums online.

I suppose you can also contact motorola support to see if they can help you recover your data before getting the phone fixed or replaced under their warranty program.

While on vacation my wife dropped her nexus 5 into a toilet in a drunkin stooper, All I'm trying to do is retrieve the photos for now, ill worry about trying to get the phone back to operational after I get some vacation pics off of it.. everything I try to do seems to end up not working or another roadblock.. ill just list step by step what happenned..
-phone dropped in water
-i remove the back cover to remove the battery and seen i need tools and its not easily removed so i left the phone in a bowl of rice for the night.. everything appeared dry on the inside and it wouldnt turn on.
-next day it did power on but the touchscreen was unresponsive, removed battery, reinstalled and a screen appeard that said android is starting and optimizinf app ** of**, would keep nearing the end and powering off on its own for hours.. manually powered off and left for another day in rice..
-plugged in and phone would turn on but would not load, the google sign comes on and gets stuck on those four circles just moving around forever..
-hold the volume down and power button to get in the options screen, try powering off and back on, restarting bootloader and etc to no avail. wiped cache and restarted. still same thing.
-when i try recovery it just goes to android with red exclamation mark.
since i got home.....
-when i connect the phone to computer the mtp? driver wouldnt install correctly
-came to this website...
-installed adb, fastboot, and the universal driver. adb doesnt see the device, fastboot does.
im lost, am i missing something?
phone is still under warranty, is it worth sending in to LG?

Can't boot, restarts constantly

Bought a Nexus 5 about 6 months ago USED. It has been amazing. I got the latest OTA a week ago or so, not sure if that has anything to do with current issues.
About 2 days ago started randomly restarting. Today, it shut down and has been in continuous loop restarting. I see "Google" and maybe even the boot dots loading, then it is off. Three seconds later, starts again and repeats. Never makes it all the way into Android system. I let it sit for a while and when I pick it up, without touching any buttons, it repeats all of this. I suppose it is probably dead in general, but I don't know. Do you guys have any ideas? Again, I bought it used and from a ma/pap store who said they buy 100 in bulk, which made me skeptical, but they also had a 60 day guarantee and it was amazing the first 60 days and even after. It has been error free for 6 months, so I don't know if this is just a random issue or if the previous owner dropped it in a lake and I got lucky, or what. FWIW the damn thing has been in a case and never dropped, so it isn't anything that I have done I don't think. Thanks for any help.
edit: never rooted, never messed with, always been stock
Another user reported some instability since the last OTA update.
Flashing the full factory images did the trick.
a friend of mine gave me his nexus 5 to repair and its doing something similar. He had ir rooted and on latest 5.1.1 (i think). Either way, he said it was randomly locking up and rebooting. When i got it it had the red blinking light when plugged so i got a new battery. That got fixed but then the constant bootloop showed itself. I flashed TWRP (many versions, 2.6.3.1; 2.7.1.1; 2.8.7.1; the one that worked best was 2.7.1.1). So, once in twrp wiped, pushed cm 12 snapshot, flashed it, pushed gapps, falshed, pushe supersu flashed. Started the system. That precise order of things (ie: pushing flashing, then pushing something new and flashing it) was what gave me best results to actually boot up at least once. Once booted up and logging in and everything to cm i had some sort of stability (even rebooting and powering off) but i think that everything went wrong when i plugged the phone to the computer and it was back to bootloops and not even getting to the recovery. Flashed everything again. Didnt work. Had to leave the phone sit for a while (without the back casing) before trying again, in order, before getting any success. Im starting to think of ovrheating but it doesnt even get that hot...
Dunno if you guys have any ideas on this. Or if i can give you mor details to help us out.
Regards!
Looks like I'm having a similar problem to what is described here, as well as http://forum.xda-developers.com/google-nexus-5/help/bootlooped-dont-how-to-enable-debugging-t3215951
I've had one of my Nexus 5 phones running OmniROM 5.1.1 for some time now, very stably. After trying out the Marshmallow preview and going back to that ROM, I started having spontaneous hard reboots and hard crashes. The phone would often boot loop before even getting to the OmniROM boot animation. It was also very recalcitrant about entering and staying in the boot loader, rebooting spontaneously shortly after rendering the boot loader screen. I was occasionally able to "grab" control long enough to get it to boot into TWRP, from which a boot to Android seemed to usually get it out of the loop and into running Android.
I've flashed back the boot loader and baseband from factory-stock 5.1.1 LMY48M (HHZ12h and 2.0.50.2.26) using the flash-base.sh script from a freshly downloaded and extracted hammerhead-lmy48m. Things appeared to be OK last evening and this morning, but things got worse today.
Now the phone is in a state where it is not responsive to the power button when unplugged. I can hold it down for 30 seconds with no response.
If I plug in USB, it spontaneously starts rebooting, not showing more than about two seconds of the Google boot loader screen. If I hold the down-volume button, I can get the boot-loader screen, but no matter how fast I try to be, I can't select anything more than "Restart bootloader" (or "Power off") option before it spontaneously reboots (to boot loader).
As far as I know, the battery had a significant charge before this started happening.
I see the same behavior if the phone is connected to a USB charging source, rather than a USB port.
I've tried pulling the SIM, but that doesn't change the behavior.
adb wait-for-device never returns, so poking it over adb doesn't seem to be an option.
fastboot devices also doesn't see the phone, for the brief time the boot loader is running.
Any suggestions on how to get this into the boot loader so I can at least re-flash it?

This morning my Nexus 5 was turned off all of a sudden after not having used it for 20-30 minutes. I held the power button and nothing. I plugged it into power and the "Google" screen appeared. It then went into a reboot loop on and off, on and off, on and off. I held the Volume Buttons and it went into fastboot, but then boot looped out again and again. Searching on Google yielded that this was indeed a common problem. [...]

Edit: Repeatedly pressing the power button seems to have temporarily allowed a boot to Android.
In retrospect, I had noticed over the last few days that the phone didn't seem to respond properly to the power button, either "ignoring" it, or when a second press got things started, it would unexpectedly come up with the long-press-volume menu.

Ok @jeffsf keep going on this thread. I had the same damn experience, that ended with RMA. LG said that the problem is related to some tension change in the power button. After the RMA I used the phone totally stock and never had a problem. Two months ago I switched to blu_spark kernel and some weeks after i noticed some problem. When I pressed the button to lock the screen, phone locked itself and then screen turned on, sometimes showing the shutdown option. So i understood that something was happening to the power button. I tried to overvolt with a +5mV on general offset and since then i never had problem. If you can enter recovery or bootloader i suggest you to flash some kernel with volt change support and then overvolt the general offset... and keep finger crossed

I got a notification for this post since you quoted me. I'm not sure if you're having the same problem but I'll tell you what happened to me, just in case. I called T-Mobile and they referred me to the nearest 3rd party phone repair shop. I went there and after an evaluation, the repairman told me the power button on my phone was indeed broken. They replaced it for $55.
The story doesn't end there though. I took my phone home and a few hours later I tried to use bluetooth and it didn't work. I took it back and found out that unfortunately, when the guy replaced the power button, he inadvertently broke the bluetooth. There's no way to fix bluetooth without replacing the motherboard entirely, which would cost $200. I'd rather buy a new phone at that point since my Nexus 5 was getting old. He refunded me, which was nice. At least the power button worked so I could use my phone. Bluetooth isn't as valuable as being able to you know, turn on the phone, so at least it was a net gain.
After that, I purchased a Nexus 6 and rooted it so I could use double-tap-to-wake (along with the automatic screen on when you pick up the Nexus 6). I also use the following app in order to turn off the screen by swiping up from the home button (I don't care about losing the shortcut to Google Now): Screen Off and Lock
I can now literally go weeks without using the power button on my Nexus 6. (I literally only use it when tap to wake sometimes becomes unresponsive which is rare.)
Bottom line: I will never buy another phone without tap to wake functionality! :good:
A local repair shop here indicated that one sometimes does changing the power switch resolve the issue. They have seen situations where the issue appears to be one of the power-management ICs. Just something to be aware of when examining the potential cost of a repair and who you would have do the work.

What the heck happened to my phone?

I have a Verizon Galaxy Note 2 i605 that's unlocked, using Straight Talk service, rooted, and was running stock Android version 4.1.1. On Thanksgiving Day, I was going to have dinner with friends. From my computer I found the location on Google maps, then sent the map to my phone. That's something I'd done many times, but this time when I clicked the link, it flashed the conformation asking if I was sure I wanted to load the map. When I clicked yes, the screen dimmed then immediately brightened and dimmed again. It continued this flashing at about 1/2 second intervals. During this time no buttons or combination of buttons had any affect on it. After about 40 or so seconds of this, I took the back off and removed the battery. I waited about a minute before reinserting the battery and replaced the back. I pushed the power button and fully expected it to boot normally. Boy was I in for some disappointment. It not only didn't boot, it didn't do anything. And hasn't since. No boot, no download mode, no recovery mode, and not recognized by the computer when connected by USB. It is dead. Does anyone know what happened, or more importantly, can it be revived?

Please Help! Stuck at boot screen...

Hello. Sorry in advance if this is the wrong thread. I own a pretty old 1 year old tablet that currently has a problem.
Important info: Android 5, No access to a computer for 2 weeks (vacation), slightly cracked screen (still works), I had to install a Play Store apk as the one I had previously was corrupt. Tablet was functioning fine until the moment of the incident (except for the play store apk, which I later fixed).
Minor detail: Once the screen turns on after a restart the pixels near the top of the screen seem to turn purple for a second when I tilt the tablet.
Here is the story:
I was watching a YouTube video and suddenly my tablet froze. I thought: "Uhh, another freeze how annoying," and waited for it to load. I did not unfreeze. I thought: "Well, I guess I'll be fine if I turn my tablet off and on. This is where I got worried. My Power key was not responding. I tried the volume keys. Nothing. I tried connecting a mouse and moving it around. Still nothing. I thought "Ok, lets try restarting it" I did that by holding the Power key down for 10 seconds. To my relief, it turned off. But when it was turning back on again, it was at the loading screen for a little to long. It usually takes 5 seconds to get past the loading screen and enter the boot screen. I decided to wait. 1 minute: nothing. 5 minutes: nothing. I got worried. I tried restarting the tablet again. I restarted successfully but was stuck at the loading screen again. The was no movement on the screen. Only the loading screen. I decided to try the restart backup button which I could activate by putting a pin in a small hole at the back. It had the same effect holding down the power key had. I decided to ue my backup plan: recovery mode. I successfully entered recovery mode. I chose the option "clear cache" and tried to boot again. No changes. I did a scan for any root errors. it said that there were 5 errors, but there was nothing I could do about that. I tried doing a factory reset, then booting up. The reset was successful, but I got the same effect as always. No changes. I gave up and tried to google a solution on my phone. Most of them told me to install a PC program, but one told me to do the same thing I already did: reset, restart. So I decided to let the tablet sit with the boot screen for 2 hours. When I came back, there was no change at all. I tried searching again for a solution. A YouTube video said that the boot time after factory resets may be long, so I decided to reset and let it sit for a bit. 20 mins later, no changes at all. Finally, I gave up and now try to ask for help here.

Was your device rooted? Did you have TWRP custom recovery installed? If you don't have either of these two things then your only option is to flash the stock firmware via PC.
Do a google for:
"Return to stock (your model number)"
If what you need is out there somewhere, that woll find the instructions, the tools and the file(s) you need.
