Hi everyone,
Ok so I have browsed many threads on bricked xoom 2 / xyboards and most have been fixed via fastboot files. My problem is when i was clearing cache from a JB update.zip I had applied I accidently whiped System... When i went to reboot it said no OS installed warning, so i freaked out and plugged it in over night so it would not do anything from that point until i could get the fastboot files today. When i had woke up the battery was completely dead I have tried to plug it in and charge but it will only charge enough to turn on an sit at the M logo screen, i can get into fastboot mode but it keeps saying battery level low charge first, but as soon as the tablet charges it stops once it turns on (the white light goes out) I have read in other threads
Well there is the problem, depending on how "bricked" it is the following apply.
Really bricked. Stuck at M Your going to need to pull the battery and charge it out side of the tablet.
Kind of bricked. Os boots but loops at animation. Turn off tablet and plug in charger.
The OS is needed to charge the tablet. All be it the whole is dose not need to load. So if it's looping while attempting to do the final boot sequence then it should still charge.
From a power off state only the minimal core stuff needs to run for the charging modules to load. That said from a power off state the entire OS does not typical load

I am willing to do what it takes to get the battery out if need be, but I cannot find a DIY on this? does anyone else have any suggestions? Im not completely new to rooting / flashing, but I have always done so on a phone an this is the first time i have ever cleared system.
Thanks

Mcgyver Battery Removal And Charge by DMD
*Fixed*
My Mcgyver Battery Removal tutorial
Here's my Mcgyver fix for no os an low battery that won't charge.
**I am not liable for any damages done to your device, there are possiblities of damaging your device***
If you can still boot into fast mode like this but won't stay on long enough it's because an os is required to charge your battery.
Step 1 - start removing the rear cover
With a small tipped screwdriver or razor blade gently work your way between the glass and the rear plastic. This process is time consuming be patient . After working the case off you will see this.
Once the case is off the next step is to disconnect the two battery cables

Next step grab an old charge cable and cut off the micro USB end. Peel back the rubber an you will find 4 wires. Black and red are the important ones, cut off others and strip red an black wires (if u have no wire stripers simply use a lighter to light the wire on fire an with a napkin pinch an pull , all off the rubber should b off now.
Now that your cable is ready remove the 2 screws holding down the wires to the battery (t5 torx bits) once these have been taken off wrap the red wire to the red loop ( tape these ends for safety ) do the same with black. Once you have them set up plug it into you laptop and let charge for 1-2 hrs ( always check on the temperature of battery for safety)
Once charged start it up and verify your fast boot screen now shows good battery program ok then proceed to rsd fastboot flash .
everything should run smooth after this.

Hey guys, have an issue that I'm trying to figure out how to deal with. This morning I woke up to find water on the window sill where my phone was sitting (charging overnight) and the LED light was on. I have the nueLight flashlight program on thanks to arrupenthal's (sp?) wm6.1 ROM, so I went in there to turn it off, only to find it was "off." I pulled the battery and charger cable and the light went out.
As soon as the battery goes back in, the light comes on. Phone isn't even on but the light is powered up. If I turn the phone on and go into the nueLight app, the high beam feature works, but the strobe/morse code ones do not.
I tried using 15 min of heat on blast in the car ride to work, holding the phone infront of a vent. Tried putting it in the freezer. Nothing.
Would doing a hard reset/ROM reflash fix this or does it sound like I have a bridged connection to keep the LED on constantly? Right now I just put a piece of electrical tape over it, been on for a few hours, battery temp is hovering around 30 C which is normal.
Any ideas on a fix? My insurance is null/void from AT&T. I'd love to get a Tilt 2 but not in the finances right now. It's either leave it go and wait til I have a real issue from the LED on 24/7, or go so far as to take the phone apart and "clean" it? The stickers on the battery and inside the battery compartment have changed color (white to red) b/c of the water so no chance at a warranty claim, plus I know if I tried pulling one over on HTC I'd end up spending $300 on something I wouldn't have had to anyways.
have you tried a hard reset when you have time? that or maybe uninstalling nuelight and reinstalling it.
Usually water wont bridge the connection for that long. it would rather shortcircuit your phone rather than bridge a connection.
I can try a hard reset. Volume down and stylist reset button right? Does that clear out all the contacts again?
I'll try whatever. All my contacts are saved in outlook so no big deal.
hard reset clears out ALL information.
so back it all up. hard reset and see if it works.
I tried a hard reset, the red/green/blue screen shows up, and then in the white down at the bottom it says serial and does nothing. No buttons make it do anything at this point. I just pulled the battery, put it back in, phone starts up as normal and all data is still there.
It doesn't make sense it's software to me if the phone is off and the light continues to shine.
its definitely water damage, ive had the same issue since i washed my phone in the washing machine. its got less of a problem as time goes by, now you can barely see the light is on unless it is dark and even then it is quite feint. annoying as it doesn't help the battery life!
Ok so I talked to arrupenthal or however you spell his name. Convinced this is not a software problem, since with the phone off off, and putting the battery in, the LED turns on. So i took the phone apart. Here's what we have:

Click here for the high res version. Looks like there's some stuff near the LED from the water damage? Any ideas?
Well...nevermind. Cleaning it didn't work, so I popped the LED off with a flathead and I think we're back in business, sans flashlight.
I had the same problem hope can help me how you do??
thankss
So my TF101 appears to be completely dead. I had it rooted and rom'd running KatKiss 4.3,not sure of which number . I loved it too. Anyway, before it died, it rebooted and would not leave the "updating apps"screen so I did a factory install which fixed the problem but only temporarily. A few days later the same thing happened. This time I could not even reboot it. I left it charged overnight but could not get it to boot at all. I think I have tried everything. I tried booting with and without being on the keyboard dock, I have tried plugging into the computer, tried hdmi to a monitor to see if the screen went bad. I tried seeing if the computer recognized it in APX mode. NOTHING. The USB charges the keyboard dock but does nothing for the tablet. The computer does not see it period. It looks completely dead. It is out of warranty but I even called ASUS and all they would do is charge me $340 to send it in.
I would love to troubleshoot to see if it is a board or battery or whatever gone bad , but I cannot find anything on the Web. Can anyone help. Otherwise it's a lovely paperweight.
It's possible that the battery has come to the end of it's life and won't hold any charge, which would explain why APX mode won't work, the PC can't power on the TF via USB, only trickle charge it while it's powered off / screen is off, but if the battery is dead then that's not gonna happen either
Not sure if the charger needs the battery for it to power on the TF too or not
You could try disconnecting the battery and plugging in the charger
Here is a good teardown video to show exactly how to get that done
https://www.youtube.com/watch?v=k-6dKsGJ4VY
Im not 100% sure, but if the dock battery is fine, you could check and see if the connections are the same and swap them over

Still DEAD
Detection,
Thanks for the awesome YouTube of breaking down the TF101. Unfortunately, I swapped batteries and still no good. Nothing happens. It looks like the old battery has power too, based on my multimeter. Is there anyone else with suggestions at this point or do I leave it as a nice paperweight?
THansk....
Apologies for resurrecting this thread. My TF101 (with dock) had also gone dead after running one of the KatKiss ROMs (maybe 4.2). Wouldn't charge, wouldn't turn on even to the bootloader or recovery. Charged it for days, nothing. I left it for dead and forgot about it for over 6 months. Uncovered it the other, dusted it off, charged it and it magically powered up. Everything was still on the tablet as it was before it went unresponsive.
My guess is that a microcontroller responsible for powering up the tablet got into a bad state. Even when powered off, these very low power microcontrollers remain on to handle the button press that powers on the device. It took the tablet being absolutely, fully discharged to clear it out of that bad state. Not just 0% as reported by the battery firmware, but a true complete emptying of the battery where its voltage drops below what the microcontroller needs to remain running.
Hopefully if you still have the TF101 after all this time, try charging it up all the way and see if it comes back to life.
Hi all...
I think my N5 is buggered.
I was at a festival this weekend and my phone battery ran out so I left it in my bag for more of the weekend. On the drive back it was working fine as I was using GPs, making calls, using Gplay without any problems. As my GF wanted to charge her phone mine ran out again by the time I got home and I went to charge it as it was down to 2% but when I plugged the charger in it would not charge. It would start charging for a second then stop for a second and then start again. So I unplugged it and went to give it a re-boot and the screen came back on corrupted like this -

I have holding the volume down and power button to get to the fast boot menu and the screen does the same thing but this time while i'm holding it the screen with turn on and off wile vibrating 5-6 times before turning off.
I have even tried using fastboot to flash the recovery image onto the phone and it says everything has worked but again I get the corrupeted screen when I reboot.
Anyone seen or know of this problem? Or is it what I expect and it's got a hardware issue and needs to get repaired?
Thanks in advanced for any help or suggestions.

It's a problem with the flex cable, the screen, or possibly the motherboard.
A few people have had this issue.

Lethargy,
I had a feeling it was going to be a hardware issue. Thank you so much for the help... I'll get it sorted under my insurance then and get myself a temporary phone until then.
Cheers
Hi, when charger is connected my phone keeps rebooting on Google logo, when I disconnect a charger it has no signs of being alive. What should I do? Help me please
EDIT: now somehow i managed to get into fastboot, but when i try to get into recovery phone reboots again and shows full charged battery. What should I do now? I tried to flash stock and unroot via nexus root toolkit, i get the same.
Hi
I have had the same problem several times.
Mine was a sticky power button on a phone I keep very clean.
I haven't seen any discussion of this so I thought I was the only one.
At first I could tap the area around the button and it would loosen up and stop.
After some time that stopped working.
I tried to open the phone but found I had no access to the power button mechanism.
Last resort was a can of WD-40 with the straw on.
I sprayed a bit around the button and played with it for a few minutes and problem solved.
I was worried about the WD-40 inside the phone but haven't had any issues since.
This was about 3 months ago and would happen to me about once a month before.
I hope this helps.

i think my power button works perfectly, because everytime i try to go to fastboot it works. Now I see only "full battery charged" symbol like this:

im able to get ONLY into fast boot. Ive tried fastboot format and flashing everything stock, didn't helped. what should i do now?
That symbol does not mean the battery is full, it means the phone is connected to a charging source.

ohh. now i even cant get into fastboot. only google logo loop
Does the bootloader re-lock when the phone reboots?
Disconnect the usb cable from the charger, then re-connect the usb cable. Does the LED blink red?
Did you try using the original USB cable and charger that came with the phone? Do you have a wireless qi charging pad to try?
I dont have original, but with qi charger it reboots a little bit more often than on the wire charger
Boot loader stays unlocked.
It didnt blink red
Are you able to successfully flash a stock rom or does it reboot before it can flash? Could be a damaged memory chip.
I had this happen to the Nexus 5 I gave my mom. It would show no signs of life from any button combo but when plugged into the charger the Google logo would appear but then turn off again. I would be able to go bootloader but then it would restart. Guessed the power button had to be resoldered onto the device and took it to a repair shop last week where they confirmed

So anybody can help me?
I suggest opening up the phone, removing the motherboard, and press and release the power button several times in a row, using lots of pressure, but not so much pressure that you damage the button.
I had a phone that would reboot or power itself off at random. I was going to pay to have it fixed but I decided to open it up, clean out the phone, press a few times on the power button, and now it works. No random reboots or shutdowns.
Does your phone battery charge to 100%?
Maybe the phone has a battery problem, power button problem, or memory problem.
Hey mates,
right now im building myself a multimedia computer in my car. I wanna have a large screen, touch, gps, 4g and good sound. So i took myself an Appradio 3 and a Motorola HD (fastes phone in my mind with hdmi). I also tried an Android TV Box (MXQ Pro+ 4k), but those really lack in performance. The Radio sends the touch via bluetooth to the phone. The phone itself sends video and audio signal via hdmi.
The Razr HD works fine, but i got 2 concerns.
1. The Battery. Right now the back of the Razr HD came off, cause of the heat the phone produces when charging, running at full capacity and lying in my glove compartment. So i disassembled the hd and removed the back cover. I was thinking of completely removing the battery, but of course it wont start up when no battery is connected. Is there a way of normally booting the razr without a battery? I was thinking of putting 3,7V to the contacts... But the battery got 4 connectors, what are the green circled ones? (heat sensor? charging input?) I red that the factory cable one can build is only for flashing and not for booting...
2. The original screen. Is there a way to fully rely on the hdmi output? I think it would give me a performance boost, if there would be only one screen to be rendered. Also it would save me a lot of battery and doesnt produce so much heat. (i know i can put it blank with "Screen Standby #root", but the performance is way more important than the heat/battery drain)
Do you have any progress in this?

1. The factory cable can boot up the phone all the way, but I've only ever managed to boot it into factory mode (or whatever it's called) without a battery connected.
And if you are going to wire up 3.7/3.8V directly to the phone, it might be better to separate the charging IC from the battery and wire it up to that instead.

2. I don't think the phone can render just to HDMI to increase performance. It will always just mirror whatever's on the screen to HDMI, regardless if you have a RAZR HD creen connected or not.
