Hello everybody,
does anybody here see a connection between missing volume buttons(physical switches on the camera module 04w2155) and the tablet doesn't start?
As backgrund info.
Tablet is doing only short vibration when trying to power on, or when connecting to charger. When connecting charger led on the back is flashing but i don't get anything on the display or other feedback except the short vibration. I suspect also some damage with the screen, but cannot confirm. Tablet has a repair of the power button.
Thank you
You might be in APX mode, which doesn't activate the display.
Press the battery-disconnect button inside the tiny hole next to sim card slot and then try to power up your tablet.
Thanks for reply/hint.
What reset did is that for around half a minute the red led was lightning continuously, not blinking. After thag blinks again.
After research about apx mode i'm more and more certain this is my situation, it's active now.
If i connect to computer, it does recognize,search for driver and then disconnects within few seconds.
Since i see this more like a software problem could i stabilise the connection to the computer and recover informations/make backup and restore rom?
Thank you!

We are making progress!
My guess - not to answer your latest question but to the original one, is that your missing volume buttons (physically missing, yes?) very much have something to do with the tablet's current condition. To get to APX mode, the tablet must be started from cold boot with power AND volume pressed at same time (physically pressed). If your missing buttons are registering as being 'pressed' all of the time, it may be difficult to create a boot situation where you can get to your android desktop.
Could you elaborate on the missing buttons?
Please someone else chime in here - I don't even have my tablet.
Thanks for reply.doesn't matter for which question. I put together any information. Issue is getting clearer.
I got the tablet in this condition and attempt repair. Power button was down so i soldered back.
Now the thing is somebody worked before in this area and i suppose the actual powerbutton is one of the volume buttons since the work done before doesnt look professional. I suppose they destroyed the powerbutton and desoldered a volume button to resolder as powerbutton. Which possibly is the case for both volume switches. Now the two vol buttons are nowhere.
The switch has 3 pins,of which the ones at the sides have continuity when the switch is unpressed.
I suppose for boot it could require that the 2 volume switches to be present, that means it could have some continuity check through the switches, and if they are not present it cannot start.
I cannot simulate the 2 buttons because for one switch the soldering pad on the board got burned.
I am going to upload pictures in 5-6 hours when i get home.
If this proves to be somehow true i would order another brand new camera module with all 3 switches, but now i'm unsure if with new board it could start, at least for flashing/recovery.
But having it vibrating and red light flashinv i see a sign it's not yet a "unrecoverable brick"
What do you think?
Thank you

I think it is definetely a screen damage, maybe a conection cord. Try to clean/replug this cord (cant remember now where it is). This short vibration indicates, that device is begining to boot. Right after vibration Lenovo logo should apear on the screen. If it doesnt - screen is down...
About power board - no connection between power and volume buttons for sure. Power button: + is central, - is other two.
stas.green brings up a good point. If you have opened up the tablet, it is very easy to disconnect the flat ribbon cable that runs the display. When I installed my 3G card the same thing happened to me. Freaked me out but it took 30 seconds to open it back up and correctly seat the cable.

stas.green you're right. the problem is with the screen. i powered the tablet and conected to the computer. i could see the memory access the files and make a backup.
i'm going to examine where is the screen problem origin and possibly to fix it. the screen cables i checked, they fit good. any other weak point known to you?
thanks for help
My next suggestion, not to fix the screen, but to get some function back - connect the tablet to a TV via the mini-HDMI port and see if you are booting to a normal desktop. Hopefully 'External Display' is already enabled. At least you would be able to test if the touch and pen functions of your screen and confirm if they still work even though your backlighting may be broken. Shining a flashlight at an angle on the screen may make the desktop visible if the backlighting is the issue.
Good luck!
My ouya is doing it all the time. I switch it off from the menu it goes alive after some time. When I switch it off with a button the situation is the same. Has anyone got the same problem?
Mine doesn't since the update. Before the last update it did after I touched the controller.
Keep in mind you can turn the ouya off now by pressing the Y button in the main menue (since update). Then it stays off.
Or you can HOLD the Ouya button and then select "off" in the popup.
Pressing the Ouya button just enables stand-by.

I have the same issue after the update. I use the "Y" button at the main screen to turn it off and select OUYA. The console will be on when I come back to the tv.
When you "turn off" the OUYA via the Y button at home screen, its essentially putting it to sleep, then when you leave and switch back to the input that your OUYA is attached to, your TV will send a "wake up" signal, which effectively turns the OUYA back on...
Yep, Using the Y button from the menu doesn't shut the Ouya off and neither does just pressing the button. Both will put it into sleep mode and it's VERY easy to wake from sleep. With earlier controllers just pressing a controller button will wake the controller and then the Ouya (the later rev controllers I got after they replaced my originals don't wake up unless you press the center OU button so they're less susceptible to this.) And the Ouya will wake if it senses activity on the HDMI port. With my TV I don't even have to change to the input the Ouya's on, just turning on the TV apparently causes enough activity on the ports that it wakes the Ouya up each time I turn the TV on if the Ouya is just sleeping.
I was really excited that they finally added the ability to put it into sleep mode from the controller. But it's so ridiculously easy to wake up that it's kind of senseless and I'm still stuck getting up and either pressing the button for 2-3 seconds and then using the controller to confirm the power off, or more commonly just holding the button for 8 seconds until it shuts down.
I really hope they do something better with the whole power thing before commercial release but there's not much time left for them to fix it.
I noticed the same and I'm on the newest update.

I'm having the same problem as well. Keeps turning on even though I don't even touch it. This sucks double cuz the ouya doesn't have any cpu governing so it's always running at full speed.
this is a FEATURE of the OUYA! It is NOT running in the background all the time! It turns back on when you activate the input. Someone has also stated that it is part of the official "features" list of the OUYA.
Here is a quote of what i posted over on ouyaforum.com
After messing around with this for a while I messed up my controller to where it was stuck on no matter what I did. Luckily it was temporary and a hard restart fixed it but it did help in determining exactly what triggers the OUYA to turn on!
This is something built into Android, every phone/tablet has it. It's bringing it out of sleep. Some phones only allow it to happen by the power button, others it's any physical button, but as far as I know all of them turn their screen on when plugged in to charge, and that's what's going on here.
The OUYA turns on whenever I activate the input it's in. If I switch to it, the OUYA turns on, if I turn on the TV when it's already on that input, the OUYA turns on.
When my controller was stuck on, I would use the Y button to "turn off the ouya" and then any button press or movement of the controller would turn it back on, just as physical buttons do with phones.
So yes, it is actually a feature, but it's built into Android and not just the OUYA. It is most likely that it does have to do with CEC, since the HDMI is looking for anything active on that input, so the OUYA sees it as being plugged in.
With that said I think it's pretty cool that it does that! I mean I know it doesn't save any time or anything like that, as you still have to turn on the controller, but it is just cool to put it onto the input or turn on the TV and the system is already ready to go.

Ah, so there's a sleep feature and a power off feature. I see.
The sleep feature is not working well. Comes out of sleep by it self it seems. While on sleep, is it turning off the 4 main cores and only running on the 5th low process Tegra core?
I believe it is a WOL (wake on lan) from the router but I could be wrong.
So out of curiousity, how does the controller decide when to sleep/wake up? It seems like every few minutes of inactivity (say I'm watching a movie and I want to turn down the volume) I need to long press the button in the middle to get the controller to turn on/pair, which all takes about 5-6s, which isn't always convenient (or say pause the movie if someone calls).
Is there a way to increase the timeout or turn it off completely via some software trick? I'm fine with running the batteries down, I will just recharge them when necessary.

You know, I was having the same issues until I figured something out. I don't believe the controller goes to sleep immediately even after 5 min of non-use. If I turn it on for the first time today, I have to long press like you described. But lets say I set it down and watch a show on netflix or listen to a song. Whether I set the controller down for 5 min, or 30 min, the next time I need to wake it up, all I have to do is press the home button once. Not a long press, a regular press - which in turn wakes it up. Now, If I don't use the controller again till the next day, it will need a long press...hope this helps.
It's like shortly after use it goes to sleep with an instant on feature, but after an extended period of time it shuts down.
The CTRLR timeout is after about 2min of inactivity. If its gone to sleep, you can usually wake it up with single tap of Home button. If it doesn't wake up, you can do the press and hold Home button for 5 seconds to turn on.
Bonus tip: Press and hold Home button for 1 sec brings up the Recent Apps screen.

:good: It's a great feature, I use it a lot, even in gamesmart mode it works!
Shame you have to switch to mouse mode to select an app.. is there any chance of better navigating the android UI in gamesmart mode in the new Android 4.4?
@vostok4 thanks for the post
@mherma thanks for explaining how this works
I was doing long press every time I wanted to use the controller. Was getting frustrated with this and started to wonder if there was a way to disable sleep mode on the controller. The short press seems to work
It would still be nice if there was a way to customize how long you need to wait until the controller goes to sleep.

@paulobrien,
I came across your review, Nice! ( http://www.modaco.com/topic/368609-review-mad-catz-mojo/ )
The controller switches itself into standby when not in use to save power, when the power / home button will glow red (it's normally blue). Switching the controller out of standby seems to be something of a black art, it doesn't 'wake up' as quick as I'd like, but after a few weeks of use i've got used to it.

I keep the thumbscrew on my at all times, for fear of losing it to.
I agree about the mode switch being difficult at times.
For comparison purposes, a Nvidia Shield is currently £279.99, also on Amazon UK and shares pretty much the same internals but adds a screen. You'd probably want a HDMI cable to play it on your TV.

You'd need a bluetooth controller for that 'similar experience' :laugh:
They are similar experience, but how you get there is night and day.
Ie, Yeah, the shield has HDMI out, I have a hacked PSP with tv out, but I could never be bothered setting it up (A/V and power).
And the same with my tablet with HDMI out, did it a few times mostly for movies.
IMO, the mojo is convenient for TV topset box, desktop gaming and moga style gaming, all ready to go out of a single box (with exceptions lol).
Actually, I wrote on my blog about all the 2013 micro-consoles, and none were perfect out of the box experiences either.

Hey, what does holding down start do?
I noticed it disables the controller for a while.
I was doing scorpions fatality on Mortal Kombat 1 on md.emu, block up, where block is start and the home light started flashing.

Holding the Start button for 5 seconds will have the Home button flash purple, clearing pairing for the CTRLR. It will then flash the usual red and blue, putting the CTRLR in Discovery Mode until it connects to a host. If the USB dongle is plugged in, it will usually immediately connect to that.
Otherwise, you can have it connect wirelessly to Bluetooth 4.0 PCs with Windows 8 (including the Microsoft Surface Pro) and Bluetooth 4.0 Android devices that have KitKat (like the Nexus 5 and 7). Just go into the device's Bluetooth settings and make sure the USB dongle is not plugged into anything.
For emus, I've been playing around with setting R3 as Start. Still trying to get used to it. :x Hope that helps!

R3 = Right analog click in, Interesting.. never thought of using those!
I'll leave it as start tho, as it plays just like the original pads :laugh:
Played around with L3 as Select and R3 as Start since Back button was usually the emu menu.... Unfortunately, didn't work out for me as I kept pressing L3 by accident whenever I was doing quick movements with the Left Analog. T_T
I've revised my control scheme to R3 as Select, and Start as the regular Start button now.
FWIW I usually just assign the Back button to the Select function - if I ever need to bring up the emulator menu I switch to mouse mode and click the back button in the soft menu bar.
Hello all,
I've upgraded to v8 and get cannot get past the prompt to press the sync button on my controller. When I do that, it the button flashes, and flashes, and flashes... but the controller never syncs, so I cannot get to use by console, it is stuck there. I usually use a wireless keyboard, but this does not get me past the screen here.
Is there any way to get past that screen where you are required to sync a remote or controller with the console?
I don't want to buy a new controller or remote as I don't use them.
Thanks,
Mark.

Try pressing home button, back button at the same time until it flashes and see if it syncs if not press home button, back button at same time for 15 sec and then disconnect power from shield then plug back in and it should work, has worked for me like that countless times

I installed my A6 pro yesterday and it was working fine..
Whilst out driving today, the screen went blank, and I can't get it back on. I've tried the reset button.
The lights on the volume button etc are lit up, suggesting there is power going to the unit..
ANy suggestions please?
Cheers
Chris
