Hey everyone,
I have an issue with the bike tablet no longer turning on.
Previously, the bike wouldn’t boot past the P boot loader. I got it into fast boot with Power + Volume Up. There, I went to recovery. This presented a screen with an error robot and text “No command.” I powered the device off, planning to go back to fast boot and try something else, but now I can’t get the device to turn on.
I’ve tried
- holding the power button for extended periods of time
- holding the power button + volume up for an extended period of time
- directly connecting the power to the monitor
- unplugging for several hours to let batteries and capacitors drain
- using adb. Adb does not see the device, though windows device manager does recognize something is connected via usb
Ultimately, the screen is a large Android tablet so hoping someone could help out. Any suggestions?

I just tried to boot in to the boot loader by holding down the volume-down button while doing a reset from android (power button, tap reset) - I know it's not the right way but I was just trying it. Anyway, now my phone won't turn on. I've tried taking out the battery, putting it back in, booting to the boot loader by holding down volume-down and then holding down the power button, but I get no vibration, nothing. The screen just stays dark.
Orange light comes on when plugged in to charger. When I plug it in to my PC (Windows 7) I get a USB connect sound which is like three low notes in quick succession and then when I unplug I get the USB disconnect sound (higher note then low note).
Any ideas?
Phone is HTC Desire X in case it's not obvious by being posted in this thread.
Thanks
Try a longer press approx for 30 seconds

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
So I had the OTA update for 5.1.1 the other day and thought "yay, let's update." it worked fine till this evening where it crashed to a power off state and in now showing the Google logo like it's about to load up and then a turned off screen.
This repeats over and over I can't even stop this loop.
Holding the power button and it just continues to loop.
Power + ANY volume button and it will show the HBOOT or fastboot menu then before I can select anything turn to the powered off state and loop through (if I'm still holding the buttons the menu will show again shortly, or go back to the Google logo)
Any ideas for a solution?
try waiting until the battery drains all the way down then hold the volume down button and plug it in. if that doesn't work then all you can do is contact google support and they'll probably replace or fix it.
Hold the power button down for 20 seconds 3 times. It helped me once with a similar situation
So I have found a solution. Instead of deleting the thread I'll leave this here unless anyone else has this problem.
It seems that trying to enter the fastboot menu when plugged into a USB seemed to work.
It was either the fact it was in the computer, the timing I pressed the "power button + power down" combo, or it had just looped enough times and decided to actually stop interrupting me using the fastboot menu.
Either way, I cleared the cache partition using the recovery and it booted up fine.
EDIT: Thanks for the help, I had tried holding the combo for a long period of time (multiple loops of the booting). I also feared letting it drain in case it refused to startup again and I would have no chance of fixing it.
glad you figured that out! android can be mysterious sometimes. especially when it's on the nexus 9.
Hello
My Kurio TAB 2 got into an infinite boot loop. The battery got completely drained and when plugging the charger it will charge for a minute and then it will try to boot again. Afterward it's off (not enough battery), then again charging for 1 minute and trying again to boot, and so on. Looks like this tablet everytime it's connected to a charging source it will try to boot if turned off...
I had to unsolder the battery and charge it manually. After that tried to get into Recovery mode but it will not work. Every time it will try to boot like when normally switching it on, and after a minute, the screen goes black and then tries to boot again (boot loop). I tried to boot into recovery mode with Volume Down + Power button, then releasing the power button and holding the Volume Down button. Also the same with Volume Up + Power Button. Nothing made a difference. Every time it will just boot in an infinite loop until the batter is drained. To avoid this, I have to always disconnect and then connect back the battery.
Also tried to boot it into recovery mode using ADB tools (with "adb wait-for-device"), but without luck.
One "interesting" thing, is that when connected to the PC and booting (from itself), I can hear the sound of "New device connected" and after 1-2 seconds the disconnected sound. These connect/disconnect sounds will happen twice in the first ~10 seconds of one boot cycle.
The problem started from one day to another. My kid was playing with it as usual and after it was discharged and turned off, I plugged the charger and this loop started.
Would be great if anybody could help or has an idea of what I could still try to fix this.
Thank you!
Hello
I have the same problem here.
Is there already a solution for this?
After leaving the tablet to charge overnight, I found that it was stuck on the wave animation. Holding the power button fixed it and gave me the ability to use it again. Unplugged charger and thought tablet was ok. After a while I find that it's stuck in the animation again, so I figure a restart would do it good, after holding the power button for who knows how long I manage to restart it, but it gets stuck at the "restarting" message. After a while it falls asleep and when I wake it up, it is once again stuck in the animation. I hold power button, but this time nothing happens, so I open the micro SD thing next to the charger thing, and press the tiny red thing beside the black thing(sd card?) and it shuts down. Holding the power button to start it takes it first to the Sony text, then some more Sony text, but after that it gets stuck in the wave animation. Another thing to note is that I was using about 90% of it's storage so was thinking this is a reason.
Anyone know of a fix?
I'm open to installing a custom ROM or factory resetting it, don't really have anything important that I want to recover, just want to turn it into something usable again.
A link to one of these guides would be helpful.
When plugging it into PC via USB I cannot get it to show up in xperia Companion. It does show up in Devices I think, but I can't use it for anything.
