Hello!
I have Desire Z, rooted with MIUI-Android ROM, which was like 3 weeks old, and sometimes during the waking through trackpad it went blank-screen but after hitting the power everything was ok (without restarting the phone).
Last night i've charged the phone to 100%, however i was using different charger. In the morning the phone worked flawlessly but after a couple of hours it hanged/crashed. It didnt boot since then. I've tried removing the battery, nothing happens. After plugging it into the computer i see orange led blinking as if it was charging and after hitting the power button it stops blinking, however no indication of booting up is present (still powered off screen and no buzz).
Any idea what options do i have?
Regards,
Wojtek
no splash screen or anything? Does adb pick it up?
I was planning to use it, but i was at work, so...
yeah!
"adb reboot-bootloader" did the trick. After that the device is up again!
now.. where is that famous "Thanks" button. I'm probably blind or something, but a few times i wanted to use it, but dont see it, haha!
Thanks a lot!
EDIT: ah, there is is..
wow easiest help I think I've ever given lol!
..well, sometimes even a simple smile can help
Cheers!
Editing this as I'm desperate for help and things have moved on since I first posted, below is where I am up to post 11 of this thread.
I flashed Vegacomb b (exe), it restarted but stayed on the warning about paying for vegacomb for 10-15 minutes which didn't seem right so I held power for 6 seconds and it turned off. After that it would never turn on or go into recovery (I know all the methods, none worked).
Today I unhooked the battery, when I plug the battery back in the screen comes on for a second but then it's as it was, unresponsive. HOWEVER, if I plug the mains in with the battery disconnected then it immediately tries booting but still sticks at the warning (left for over 20 minutes). If I plug the battery in while on this screen then remove the mains it stays on. The power button is unresponsive through this so I still cannot get into recovery.
Any more ideas that haven't been mentioned?
I've tried well over 100 times to get into recovery but it's not happening
anyone willing to have a go at fixing (cheaply!) if I send them it?
Original Post:
Hi guys, just managed to (re?) install Vegacomb (b, from exe), it restarted but stayed on the white screen with the warning text about paying for Vegacomb for over 10 minutes so I held down the power button to turn it off, now I cannot do anything to boot it up (tried holding power button down from 0.5 seconds to 60 seconds!), it also won't boot into recovery. Is there anything at all that can be done to get this going?
cheers
OK, I've tried holding down back while plugging in (fully charged btw), tried all variations of button presses with back and power, with and without USB, with and without power cable.
Only got until 10PM (UK time) to get this sorted (it's now 6PM) so any help/advise would be appreciated
Flash back to modded stock then try again.
From modded stock go app drawer and run recovery
From recovery wipe data, cache then go advance then wipe dalvik
Then press back
Then install zip from SD
Choose vegacomb from whatever directory on your SD you copied it to then confirm
If you ain't Got Vegacombe zip then download it.
Or you could run the .exe again but the above is my preferred method.
Also you might need to download modded stock v2 if you ain't already got it.
Good luck.

the Vega won't turn on and won't go into recovery, cannot flash anything, nothing comes up on PC, tried all variations of the back and power buttons (inc back, plug in power & usb, press power, leave 2 seconds and release back) over 100 times. it's like it's dead.
the only thing it does is show a blue LED when I plug the power cable in
I've read that if you got less than 50 or 60% battery it wont go into flash mode (back button 2 seconds - power & back 2 seconds)
Have you got enough battery cause mine takes half a day to charge.

100% (solid blue LED), been on charge for over 24 hours
I'm baffled mate, I've had same issue couple of times but after 10mins or so I've always got it to power back on.
Bricked
I've had the same problem and although quite drastic, remove the rear cover and unplug the battery connection (the multipin one with red and brown/black wires).
With the mains plug out,i found that if you press volume up and power with the wires unplugged and leav eit for a few mins then use back + power it will start as you need it to.
It may take a few tries but i have managed to do it following this procedure about 7-8 times.
Hope this helps.

I had trouble getting into recovery when the Vega was 100% charged (i.e. charge led was solid blue). When I let it discharge a little so it was flashing with the charger plugged in, I managed to get into recovery then.

I can't discharge it though as it doesn't turn on, left it 14 hours from last night, back at work again now and it still says fully charged
got the battery disconnected now to give it a try
Disconnected battery for around 10 minutes, put it all back together, still can't boot or get to recovery
EDIT: it works when the battery is disconnected (goes to the Vegacomb warning screen but no further, cannot power off or get to recovery still)
any ideas?
Anyone got any ideas?
it's meant to be unbrickable from what I've read so there must be a way around it but I'm out of ideas!
its user error. remeber to put it into recovery mode you need the power cable plugged into it too as well as usb.

Hi, this may not help but i had trouble flashing the stock rom because of the battery being fully charged, could only get the screen to light up so left it over night and then went through the normal routine and got into recovery.

Hi there
Just one question, how do you know for sure it hasn't gone into nvflash mode?
I know what you are going through trying to get the ruddy thing into nvflash, it's a mare if you don't quite get that timing right but seeing as the screen doesn't light up when it's in nvflash what is telling you whether you are actually in it, other than the screen coming on to say you are not or relying on a windows message?
As I said I had the same problems many a time but I use Audi tool now to tell me if nvflash has started, I got it off the Modaco forum, but when you are in nvflash it actually tells you so rather than relying on perhaps windows to tell you it has happened
If you haven't come across the audi tool before then just do a search for it on Modaco, I don't know if they have got it here on XDA.

wow, i'm quite surprised by the number of people who are taking their batteries out when they think there is a problem. You should never need to do this unless it is actually faulty.
Ok yes the Vega is nearly indestructible I have had my in a complete mess many times and have never had to do anything that hard to recover. Some times it will be a pain to get into nvflash mode but this can always be done just have to be patient and know a couple of tricks.
If you have tried the back button and then the power a few times and nothing there is another method.
Instead unplug the power then hold the back button down, whilst holding down the back button plug in the power release the back button after a couple of seconds (I like to count to 5)
I am hoping that you already have the USB cable connected and the right drivers installed on your PC.
Billy..
If you need more help head over to TabletRoms and look in the Vega forum (sorry XDA guys just there is a lot of other useful information there)

TabletRoms has been no help for me, there's been no reply at all for my problem but there has here and at MoDaCo. I pulled the battery as a last resort as NOTHING is working, I've tried all the tricks at least 2 dozen times, some a hundred +, including the one you mention
Well I don't want to teach you to suck eggs, but I take it you did use Audi to delete and replace your drivers.
And then when powering on the Vega you held the back button for 2 secs and then the back and power buttons for 6 secs to get the Vega detected?
For me I can only see that there can only be 3 other possible causes
1./ the back button is broken on the vega
2./ The USB port on your PC or on the Vega has gone up the swanee
3./ The USB lead is no good
The Vega may be unbrickable but if the back button or the USB port has had it then .....
Yeah, tried it, cheers.
Thought I'd pass this fix along.
I have a rooted nook that would not power up (stuck on last display screen). When I'd plug it in -- it showed a GREEN light (already charged). I tried all of the reset fixes (20 seconds hold, 1 min hold, wait a minute, 15 secs) -- nothing worked.
Finally, I pulled it apart using this tutorial on Youtube:
[Can't post link because I'm a newbie --- just search for "How to Take Apart a Nook Simple Touch"]
Very easy to do if you have a T-6 torx driver. I unhooked the battery. Held down the power button (white button if disassembled) for about 30 seconds to discharge the board. Then hooked the battery back up, reassembled, plugged in -- and it started charging (orange light).
It looks like the issue was -- the nook was registering the battery as fully charged -- and it was completed depleted. The above fix seemed to reset it.
Hope that helps someone.

I also had this problem this afternoon. This procedure worked for me too. Thanks a lot because it helped to revive my reader.
However, for Nook to have such a problem and we need to fixed it in such a complicated way is not acceptable.
Fantastic. I had the same problem and now it is solved. Thank you.
After I bought a Nexus 7 my NST was resting for a while. Now, when I wanted to use it again, it was totally dead. Then your tip bring it back to life.
Thank you. When plugged, instead of "Charging (AC)" my nook was showing "Not Charging" in device info/battery. And in the end, it went dead.
After your fix, it works
That's the ticket

Just the tip I needed! :good:
Thanks!
That seemed to work
It's now showing the "Your Nook's battery charge is too low to power up. Please wait 15 minutes! screen and a loading animation :good:
I was seriously worried.
This is really weird...is there any reason for this issue?
I am quite new to the nook in general. (Nook simple touch glowlight in my case.)
Maybe we can check for similarities and find what was causing the problem.
So what did I do to my Nook:
Rooted, Nook Manager
Nooks gapps flashed, market downloads work (search not)
Installed a bunch of apps
Installed a custom Launcher (Lightning Launcher)
Installed Swiftkey as a custom keyboard (needed several language charactersets)
Left Wifi turned on all the time
Used the feature to restore the glowlight setting after being woken up again
Used the setting to skip the lock-screen swipe
Used a custom screensaver/lockscreen text
Changed button links in the main menu (n-button) to adress the original home, as well as the custom launcher home
That's what I can remember :/
And as far as I can remember I had more than 15% of battery (at least).
With the 1.2.1 software there is an automatic shutdown that kicks in at around 20% battery.
It doesn't work very well.
It will also give you warnings when it's under 20% but plugged into the wall and charging.
Green light issue, fix not work
I recently got a brand new nook simple touch and after trying various fixes to try and start my nook up I came across this. I was hoping this would work but it is still on green when battery is plugged in and charging off mains. The light is also green when plugged into mains without battery attached. It wont go past the "Fully charge before first use" start screen and can't find any more information on what to do.
Any help would be greatly appreciated.
Thank you for the fix. It worked the first time I tried but after only one day the problem presented itself again and after that the fix doesn't seem to work anymore. I'm leaving the battery disconected a few hours in addition, to try if it fixes this problem completely (but I'm not too optimistic).

This firmware, does it still count even if you have rooted the device? If so, do you think a downgrade to 1.1.1 would fix the problem? It is rather funny that I didn't have this problem until a couple of days ago, even if my NST is only 2 months old!
Update:
It seems that my battery is not yet dead after all. It turns out that I was measuring it wrong (thank you Engineering degree) and now it reads 4.15V as it is supposed to.
So, that brings me back to the theory that there is something wrong with my software. Right now it can boot for a few seconds but as soon as it goes to sleep mode (either by clicking on the "power" button or just waiting), it freezes. I recovered the official firmware and the problem persists.
Thanks, this trick fixed mine too!
Does anyone know if this fix can be achieved by simply charging the nook for an extended period of time? I have the exact same problem but I'm not so sure about opening the back cover as it voids my warranty and I only purchased this device in early June, and the problem appeared by the end of June :/
I have to confess, I never did charge my nook fully when I bought it as recommended, and simply dived in to using it as soon as the battery had a sufficiently high enough % as I was too excited lol

I find it acceptable. After all, if we weren't messing around with the devices in the first place, we wouldn't ever need to do this.
Plus, really, it's not that complicated. A couple of screwdrivers and it's open. I mean, should we expect it to open itself with a voice command or something?
Anders
Thanks, this method worked ok with mine.
HI dudes,
it seems I've got a similar problem, green light on usb and stuck on "YOur Nook has turned off completely"
I take it apart with no success ... any idea ? Mu NST is nearly brand new, ever used a lot ...
thanks
I had the same problem, the reason was completly dead battery. After bat replacement nook works great!.
When battery have to small voltage, noow won't start to charge. You can try with external charger, to bring battery to life.
I think some nooks was matured in stock, thats why battery was completly discharged...and wont charge with nook.
Nook showing green light, main board drain and nothing
My Nook shows the green light when plugged in either to the pc or wall charger. I've held down the button twice for 30 seconds and disconnected the batery holding the power button 30+ seconds. Neither worked. Any more suggestions? I do notice a slight flicker of amber whilst holding the button down with the power cord plugged in.
Any help would be greatly appreciated!

my att g2 4.2 rooted stock rom worked normally last night, this morning I plugged it into the car charger and it displayed it was charging with 2% charge present. I pressed the power button the boot animation began I set it down and when I picked it back up a few minutes later to use it...well nothing...the charging indicator led wasn't lit and when I pressed the power button LG appeared for only a split second then went black. when I plug it in same thing, LG logo for a brief second then disappears. I haven't done anything recently except xposed modules, no flashing of anything. any ideas? thank you guys
It happened to me (on other devices) when I let them discharged too far. Just allow it to charge awhile then try to hold the power button
for 10-20secs ... The NookHD+ were the worst in this situation (it won't charge sometimes, I had to plug/unplug a few times to initiate a charge, I was almost about to RMA one of them).
something else that's odd
when I plugged my device into my laptop the laptop acted like I just plugged in 12 different things that all needed to have their disk formatted. what is going on? wierd

try charging the device in offline mode ( turn it off and let it charrge for a while) and then turn it on . mind wouldnt turn on because of very low charge yesterday. doing this helped
update
I let it charge for several hours, nothing...it appears to be in some kind of boot loop. I can't turn it off all the way, I hold the powwer button for tensec or so and the LG will appear for a second then disapear and then the back light stays on. oh ya, when I plugged it in a few hours ago it wouldn't turn on but the red LED was flashing. I'm not sure how long it stayed on, but it was off when i got back to it several hours later. thank you for your time fellas!
If you can get to recovery at all, leaving it on charge in there. Has saved me in a similar situation.

Could have been the power switch that makes the phone short circuit and goes off anytime.

Thank you sirs, unfortunately still no good
it sounds like you had the same thing as everyone else yesterday that had twrp installed and the carrier automatically updated the system.
I could not get my phone recognized by the laptop and had to use pdanet drivers, which finally worked, but I still had to dig for the device. then had to flash back to stock. There is a pretty good thread on this topic, already. Search for it in the developer section. Do not skip any steps, such as setting the date back to jan2012 and turning off the internet. go slow and methodically, or you will miss a step and get frustrated.
Hi guys,
My Nexus 7 (2012) turned off(not properly) when the battery level was low and won't power on. I tried a battery from a working tablet and tested my battery in another tablet. It seems like the issue is somewhere else.
These are the things I tried:
- leave it for a couple of hours charging (no battery sign at all)
- hold the power button with/without the volume levels while it being both connected and disconnected.
- tested my battery in another tabled and put a fully charged battery from another tablet
- made sure that the battery is connected
There was one more thing I tried - to press the Power button with no battery inside but the tablet being connected to a laptop via the USB cable. One could hear something like a boot noise coming from the tablet (doesn't happen when the battery is inside)
In December, 2015 I installed a Custom ROM with android 5.1.1 which I found here http://forum.xda-developers.com/nexus-7/development/android-6-aosp-grouper-t3268172/ (the thread was renamed and is now about the Android 6 update) The tablet worked fine for these 3 months but one day when I was checking my email it went off and won't respond to any actions.
Could you please help me to fix it? I'm just not ready to give up on this tablet. Thanks!
Both you and i, same model, essentially, the same circumstances. I also tried every method you mentioned as well. Even down to the flashing of a rom. Same results. I even tried "jump starting" the battery. Not wanting to give up on it. It sits in my closet like that boy in A.I at the bottom of the ocean, waiting... I know that is not the reply or help you were looking for. Just so you know, you are not alone..

Well, that's a good start, at least I am not the only one!
Have you tried to connect your device via USB? My laptop can see a connected device but it can't recognize it and I hear some sounds coming from the tablet when I try to hold the `power` button. This made me think that it can be a display/screen related, so the device works but we can't see it due to the broken screen/display. Don't know how to check that though.
Same here, stock Nexus 7, won't turn on, just switched off one day and won't come back on, have tried everything as suggested above, can't get it to flicker, doesn't even register the power connection with a green light or anything

Try replacing the screen, just to check. If that doesn't fix it, at least you have a brand new screen!

let it sit on the charger for a hour, then hold down the button for 20 sec
same issue here as well ive had it for about a year and im not able to access anything via my pc google help forums had no answer either, looks like we may be screwed..........
Hi, I just had same issue with my tablet only thing is that I was using it with ~20% of battery, nothing special - browsing the web using chrome, then the screen lit gray and shut off. After that no response either from charger, holding power button for 60+ seconds didn't work either, tried re-connecting the battery, still with no signs.
And then, I tried to plug in the charger and then pressing VolumeDown+Power immediately after connecting the charger. Suddenly got some response, that battery charging icon appeared, and it shows my battery charging, but from 0%. Still waiting to charge a bit until I can try to boot it.
I'll update this post with any news.
EDIT: When I connected my tablet to the charger it had that hissing sound, but after few minutes it stopped.
After 15 minutes of charging I managed to boot my Nexus7 with 7% of charge in it a that moment, It seems to work for now.
Summarry of what I did to solve my problem:
1. Opened the back of the N7 (I used a guitar pick for this) and re-connect the battery.
2. Then plugged in the charger and at the same time pressed VolumeDown+Power, battery icon lit up but went out, repeated step 1, and then step 2 again gave me animated battery charging animation which showed up for like 10 seconds
3. Waited for 10-15 minutes and tried to boot normally. And it works now

There was one more thing I tried - to press the Power button with no battery inside but the tablet being connected to a laptop via the USB cable. One could hear something like a boot noise coming from the tablet (doesn't happen when the battery is inside)
In December, 2015 I installed a Custom ROM with android 5.1.1 which I found here http://forum.xda-developers.com/nexus-7/development/android-6-aosp-grouper-t3268172/ (the thread was renamed and is now about the Android 6 update) The tablet worked fine for these 3 months but one day when I was checking my email it went off and won't respond to any actions.
Could you please help me to fix it? I'm just not ready to give up on this tablet. Thanks!

Honestly, I do not think it is the battery, I can see the Charge signal, and the Battery is showing 1,784 VDC tested unplugged and disconnected, my smart young co-worker seems to think POST is failing, I still never see a "Charging" indication.
Does anyone know , Is there a fail safe, say the battery is disconnected, and usb charger is plugged in, will i just see all 5VDC at the sub port, ?
I never see a screen flicker, DEAD battery sign, nothing.
co-worker, tried some things that made sense when he explained what he did, I would have to agree with him.
Now it is rooted, 4.x something I forget, Never went to 5.x did once early and did not like it, Back stock, ran 2 days no issues, Rooted again, 4.x still do not remember, worked great 3-4 months, Sons ran it to DEaD and that was it, put it up for 90 days or so, wife got new tablet, kids have Fire each, and here i am tabletless, CRAP, did not want to throw to much $$$$ at this thing, nor did I want to buy a new one.
Samsung Tablet here we come.
any body want this Nexus 7, it is a 2012 model.
