Hello everyone.
A few days ago my MK808b stopped working.
At one point I was on the screen and an ad appeared saying "updating the android system", or something similar. After a while, the system was restarted. But it never starts again. It got struck at the beginning and after 15 minutes of waiting, I decided to disconnect it and reconnect it again. The problem was that it never started again.
Nowadays when you start it, the Linux penguin's are shown for a few seconds and then the screen gets black.
I tried to enter the hard reset mode by I couldn't.
I press the button as it is shown in the tutorial, then I plug the stick to the pc/tv but it didn't enter in flash mode.
I have seen on youtube a video about how to get into flash mode, you press the button and then connect the stick and that's how I do it. I notice a difference between the youtube video and what i do, and it is that even having pressed the button, as soon as I plug the otg cable on the pc, the blue light turns on. But on the youtube video while the person is pressing the button, the blue light is not on. It turns on when the guy stop pressing the button. I guess there's the problem.
I've tried two different USB cable and have had the same result. I also tested on the PC and the TV. I do not know what else to do.
Can anyone help me to solve this problem?
Thank you very much!!!!

Hey guys.
I have an interesting problem. My Fuze battery drained a few days ago. After I plugged it back in and booted the phone, there is no light on the screen, keyboard or the button and no charging like shows up on the center circle.
After plugging it into the wall and powering it up, i can hear the phone booting. Once booted i can call the phone from another phone, the phone ring and I can press the talk button and take the call/press end to end it.
I tried doing a (blinded since there is visual light) hard reset (stylus/power button/volume button down/up combo) but unfortunately I have one of the EnergyROMs where the volume button functionality was not working so i dont think .
I also tried plugging the phone into USB to see if i can flash another rom, but the computer does not even recognize a device has been plugged in (even if tried searching from it using device manager)
Searching the posts have not yielded any information. Should I consider this phone dead?

Do a search on the MTTY tool, this might be able to connect & hard reset the device. Keep playing with it, you may get lucky or get some better advice soon ! Good luck
My transformer has been my right hand since June and all of the sudden I'm without it. Was listening to a podcast via beyondpod this morning and paused the audio via my BT headset. Went to a meeting, then lunch. Came back two hours later and my tablet wouldn't turn on. I figured it was a sleep of death that randomly occurs so I held the power button in for 30 seconds or so to reboot, but that didn't work. It was still on because I could hear audio notifications for calendar appointments.
Tried the power button for 60-90 seconds, still nothing on screen. In the past I've been able to plug in the charger when this occurred and it would pop the screen on, tried that, but got no results.
I tried plugging it into my laptop to see if I could get ADB active and do a reboot. Windows saw the device and loaded the ADB driver, but if I tried adb devices it showed no devices. I long pressed the power button again and the windows device manager reset, adb devices now showed the transformer, but in offline mode. I couldn't run any commands.
Next I tried the "soft reset" utilizing the volume up and power button. This didn't do anything, except that the next time I attached it to my laptop it prompted me for an APX driver. I didn't know at the time this was for NVFlash (I rooted my device before the SBK was out with the initial blob tools from androidroot.mobi).
Now when I hook up my transformer I get no response from my computer and no response from the buttons on my tablet.
I'm at a loss and would love any suggestions or ideas to get my tablet back up and running.
This is resolved, I was finally able to get it rebooted via the volume down button and power while hooked to my laptop. I have no clue what was going on with it, but its still acting hinky.
Do we have any hardware diagnostics?
my tablet just started doing the same thing. O_O asus is trying to get us to buy their new slates, so they broke our current ones. /s
Something is seriously wonky here. My wifi keeps turning shutting down but being stuck at turning off. My power button is very inconsistent.
I think I'm going to fully wipe the system and start from scratch...
Been a couple months, but I'm back in the frozen state again. I charged my TF101 over night, pulled it off the charger and validated it was in a SOD. I put it in my sleeve and headed to the office. I turned on my BT headset to listen to a Podcast, but it didn't connect. I grabbed the tablet and it was screen on, frozen at 7:29am.
I can't for the life of me get this thing to reboot. I've held the power button in for 60 seconds, tried power button with volume down to boot recovery. I tried on AC power and off. I tried to hook to my PC, but the USB is not recognized at all.
I don't know if I just need to let this thing die (which will take forever) or what to do to get this rebooted.
Power button feels like it is catching when I press it in...
If you take off the outer bezel (be mindful of your micro sd card if you have one) you can push the actual power button itself. It should be a simple hold the button down for about 3-5 seconds and it'll reboot.
Hello people
I made some settings on cenovo mini pc 2 bios and now i have no video exit on hdmi.
When i turn on, looks like working but nothing on tv
The cenovo support don't answer my email
I need to reset bios to defaults
I disconnect the battery for days but nothing...
any help on this?
thanks
Same thing happened to me. What I did was disconnect the battery. Plug in the power while holding the power button for around 10 seconds (maybe more) until the blue light went off. After taking my finger off the power button, I pressed and held the button until the blue light came on and the sucker booted up. Hope that helps.
MWA.
Anybody know how to set the bios to auto start when I plug in? Without physically pressing the power on button? No normal bios configuration that I can see? Any help greatly appreciated

I also change som video setting in BIOS and had no video on HDMI output.
It is possible to reset it, but I can not tell yuo how. I already did it two times, but each time after two hours of experimentation. You have to play with power button (long holding and clicking) after unplug and plug again power cable. Getting red light is definitely step towards success. I hold your thumbs.
Also need to reset my bios, since my unit is not booting properly, blue led keeps blinking.
Any suggestion?

Hi guys, made a similar mistake apparently.
Story:
Tried to reuse that Cenovo Mini PC II as ioBroker server for smart home.
Installed CentOS 7 onto it, install went fine, first boot = Kernel issue.
Installed Ubuntu 18.04 live server, all went through, first boot = Errors a la "Cannot enable port 1. Maybe the USB cable is bad".
Now i have no USB enabed and therefor i cant use a keyboard and do nothing.
Tried a BIOS setting found in a launchpad, now apparently the system boots very well in Ubuntu till Login screen = but no USB keyboard. Cannot do anything, as SSHD isnt running yet.
xHCI handoff - Disabled
EHCI handoff - Disabled

Apparently i disabled something i shouldnt have done.
The tips on resetting the BIOS in this thread here didnt helped yet.
Did anyone come across the actual repeatable way of resetting the BIOS on that Cenovo?
Unfortunately, I’m in the same situation. Does some of you maybe have some tips how to reset the cmos? Already tried by holding the powerbutton & pressing some times, but without success. Hope somebody had a magic tip for me.
Thank your very much!

OK so 15min ago my phone was working fine.
I plugged it into my computer via USB to I could copy some videos and my PC didn't detect it so I rebooted the phone to see if that would help....
From that point on, it doesn't go past the initial "Samsung" screen. Well, it sort of does... regardless of any button combinations I press while booting up it always goes into a bright write and green screen that isn't normal. It is some sort of ghosted or washed out image.
From there the only thing it responds to is a forced reboot and it loops back to this again.
I've tried every button combo available and they don't respond. I cannot get to the download menu or the recovery menu so I can't reload the ROM or the TWRP recovery.
I've never seen anything like this in over 10 years of rooting phones... and the worst part is that I wasn't making any changes, just doing a reboot.
Any ideas of the problem?
Was watching youtube videos last night before my phone died, now I can't get it to start boot into the OS. Not sure if this is relevant but my power button had been a little finnicky- rather maybe not the power button itself because it doesn't feel stuck or anything at all but I noticed that it would take an extra second or two after pressing the power button to get into my lock screen. I never really paid attention because it only happened once in a while and I would just restart my phone and be done with it. However I can't even get into the lock screen or anything now.
After my phone died last night I plugged it in right away and came back a while later to turn it on. I tried turning it on but noticed my phone just kept rebooting. It's still repeatedly rebooting and I can only get in the fastboot menu by holding down both volume buttons when rebooting. I get the options power off- which just reboots it after a while, start - which just reboots the phone, restart boot loader- which literally takes me back to the same menu, recovery mode- just reboots and show barcode which shows the barcode at the bottom of the menu.
I've tried downloading the qualcomm driver and trying to get into EDL mode but don't see it on my pc or msmtool, i'm also not even sure if i'm trying to get into EDL mode correctly. I've tried disable Driver signature Enforcement and then redownloading the qualcomm driver but still no luck. I don't know what else I should try. Someone please help me out, i'm pissed this happened just because my phone died, about to have ptsd whenever my phone is at 5% fml.
Also after seeing the 1+ logo and powered by android on the bottom, sometimes I would see like a line of color, which I would assume is text not being rendered all the way, fade out and then the phone shuts down and reboots itself.

Which OOS build are you on? And your device is unlocked or not?
Getting into EDL mode is tricky. Power off device completely. With the device powered off, hold down volume up and volume up at the same time, keep them pressed all the time, and during that time plug into PC (phone all the time powered off). Still hold both of the buttons. By the time you plug into PC, you should be in EDL mode, BUT it only lasts about 10 seconds. I mean you have to click start in this 10 seconds time bracket, other way phone exits EDL itself. After you click start, you can release button, obviously
