i have this tablet which i think is bricked, it wont turn on even if i hold down volume up or down. when I connect it to the pc, after 30/60 seconds the com port appears (screenshot), after 1 second it disappears and continues like this. would anyone know what to do? flash a firmware? in the screenshots there are all the information of the motherboard
similar issues i had with my chinese tablets. The core issue i figured was that they don't hold charge any more and the battery drops like 20-40% with every restart. so the best way to get this up back is to put it on charge for few hours. then hold the vol up + power button, you should see the recovery mode/options page where when you press vol up button you can choose between 3 options of recovery, fastboot, normal. keep presessing vol up and go to normal and then press vol down to reboot into normal mode. if you have a different battery to replace, start there. Good Luck!

Hey guys i got a galaxy tab, i was trying to root it and do a custom rom on it.
I put all the files necessary into the SD card and turn off the tab
then i went to hit vol down (button farthest away from the power) + power
Now all it is a black screen, i cant do anything, cant turn on or off. I plugged it into the computer and it installed some Nvidia drivers.
can anyone please helpe?
thanks
Sounds like the Sleep Of Death this and other Tegra 2 devices suffer from. Try holding the power button for 30 sec.
ok, so i tired to hold the power button for 30 seconds, nothing happens. I tried to do it with it plugged in and no plugged in. Any other suggestions?
i also have no idea if the tablet is on or off because nothing happens now when i plug it into the computer or press the power button. makes no sound. nada
no 1 else has any ideas?

i have the same problem
do you resolve the problem and how ?
Try again holding vol down (that's the button CLOSEST to the power) and power. If you can get to download mode your good.
Hey guys wondering if anyone experienced the phone being basically bricked without actually unlocking, rooting or anything.
It has happened before one, just laying on the table and the phone turning off but it came back on after a while.
Today it occurred again but has not turned back on for two days. When charging the only light is the LED flashing constantly every second. If I hold the power button and volume up then the flashing of the LED changes pace to One long flash (1 sec) to two quicker flashing ones (.5 seconds). If I unplug it and plug the phone back, The LED flashing is back to the original constant pace.
When unplugged sometimes holding the power and volume up button initiates the LG logo and then turns off and then shows the logo once more and then turns off for good.
If I plug this into the computer, its like someone ejecting a usb and plugging it in like a maniac. I heard the connecting and disconnecting sounds from windows nonstop like as if its about to blow up.
I've tried holding the power button for a minute the same goes with different combinations with the volume buttons.
The only thing I haven't tried is opening the phone, kind of afraid I will mess it up. Any solutions?

Never heard of this but I can throw a few suggestions out. Try unplugging, then holding both Volume buttons and the power button (All three) for about 10 seconds. Try different USB ports.
Try this if all else fails: Source: http://cellphoneforums.net/lg/t348484-perform-master-hard-reset-lg-optimus-g.html#axzz2YPtvkfDk
To Perform a Master Reset via Hardware

3. While both the Volume Down key and the Home key are held down, press the Power button.
4. When the LG logo appears, release all the keys.
5. Scroll to and highlight wipe data/factory reset by pressing the Volume Down key. Then press the Power button.
6. Scroll to and highlight Yes – delete all user data by pressing the Volume Down key. Then press the Power button.
7. As soon as the wipe has been completed, press the Volume Down key to scroll to and select wipe cache partition. Press the Power button when ready.

Sent from my LG-E970 using xda app-developers app

Anyways, doesnt matter guys thanks for trying, decided to just go in att and buy a samsung s4
Phone was running LP Pacman rom and did fine for several weeksbut then started bootlooping for no apparent reason. Now it bootloops if I plug in the charger cable or hold down both volume keys or the volume down key even if I dont press the power button. If I press the power button by itself without plugging in the charger cable it doesn't do anything. When I take out and put in the battery the "SAMSUNG" logo come on momentarily but then nothing. I cant get it into recovery or download mode and Odin doesn't see the phone. I didn't drop the phone or get it wet or anything. Any ideas? does this sound like a hardware problem with the power button?
Hello,
I think I might be at the end of the road with my tablet. I've never rooted it or tampered with it in an way, however yesterday it locked up so I did the usual soft reset (hold power and vol+ for 10 seconds) I then turned it back on and the sony logo popped up, but there it just hung. If I press and hold the power button it switches off, a brief press on the power button brings it back on in the same state. So I go Googling, including looking at threads on this site, all seemed to advise to try to get the Android recovery menu up. on the Sony this is done by holding the power and vol+ and then releasing the power button (only) when the son logo appears (this process to be started when the tablet is off) so I did this, and no response at all. Worse than that, where it would turn on and instantly hang, it now doesn't turn on at all. Hooking it up to my PC I can see the device in device manager, but it tells me my usb device has malfunctioned.
At the moment, my thoughts are to open it up, to:
1. Check that the power/volume buttons aren't stuck in some way (preventing the boot command being given correctly)
2. Remove and resolder if necessary internal battery to force a power cycle.
3. Bin it and get something new (it is 2.5yrs old so no big loss i suppose)
Any ideas where to look or similar experiences?
Thanks
Samsung Galaxy S9+ No custom, Just a normal phone from T carrier.
The situation is as follow. I wake up everyday and cannot turn on my phone, the screen is black but I hear it beeping when i press the volume keys. I do a Vol down Power to restart thinking it will , it restarts but the screen is black and unresponsive no matter what I do, the Power button is still functional at this moment.
What I quickly did is I connected the phone to my monitor using USB-C and i have a mouse connected to the internal KVM of the monitor- , perfect got excited that the phone at least works, on the monitor it shows up perfectly, I can control the phone with the mouse, enter my 4 digit password, works. That was the situation yesterday. Should have backed up then but didnt.
Today I wake up, the Power button does not work, so I read and find out that I can go downlead mode which I did using the Vol down and Bixby and plugging the charger.
tried the Vol Down and Power to restart it does not, so again I go in to the download mode and accidently press Volume up, Now I am completely stuck on Downloading... Do not turn off target
1. Power button does not work- I have no idea how to get the past Downloading screen now
2. Would I be able to recover anything it its really dead?
3. Any tips?
