[Q] TF101/Megatron Bricked?

Hi,
I've been running Megatron ROM for the last couple of weeks with no issues. Tonight when I turned on my tablet it offered me a ROM update to 1.1.3, so I downloaded the update, rebooted into recovery and installed the zip.
When the tablet restarted it kept saying "unfortunately system ui has stopped" and I couldn't access the menu buttons at the bottom of the screen. I managed to get the tablet to power off and I was going to boot into recovery, wipe and reinstall the full ROM again but I couldn't get the tablet to power on.
I plugged it into the wall charger and managed to get it to boot (system ui crashed again) so I powered it off again and now it's completely dead.
I've tried to power on with all combinations of the Vol Up/Down and power button, nothing.
I guess I wait for the battery to discharge and try again?
Any other ideas? Am I bricked?

1.1.3 is a update only. Install 1.1.2 from the thread and then 1.1.3
and delete this directory "/data/data/com.android.providers.media"

I can't get the tablet to power up, it's dead!
I'll wait until the battery has discharged and try to power on.

connect the charger. if it doesn't power up, hold the power button until it does

I held the power button for 5 minutes, nothing.
Will try again tomorrow, the battery was at 45% when it died.

Still couldn't get it to turn on this morning, i'll keep trying over the weekend.
If I still can't get it to turn on after a few days I'll try charging it overnight to see if I can revive it. It's looking very bricked at the moment though

Let sit for a full day or so
Plug in the charger to the tf but not the wall and ground it somehow (piece of metal etc.)
Hold the power button for 3-5 mins (to discharge)
Shout, PRAISE ODIN!
Plug in tf to wall for a minute.
Unplug
Hold power.
This is how I revived a Sph-d700 that I had in a really bad state, the odin step is crucial. Good luck.

Is it not even possible to boot into the recovery mode when you only plug the tablet to the PC?

last case scenario, try and boot into APX and use adb to reinstall your system

I had it attached to my pc last night and tried all combinations of vol-up/down and power, the tablet never appeared in device manager. I understand that APX mode the screen stays blank but something should appear in device manager, right?
I'll see if I can get any life out of it tonight and if not, i'll give it a charge and try again tomorrow.
Thanks for the advice everyone.

Guys, after a 1 hour charge i've managed to get the tablet to boot again.
System UI stops on loading.
I've used adb reboot to get into CWM, the up and down buttons work but the power button doesn't respond. I can't choose any options in CWM.
How should I proceed to get the tablet usable again?

You can use the "touch" recovery. Use the repacked by Roach.
It only read from the internal SD card so put all your files you need to flash there.
Just DON'T use a superwipe script or you'll have nothing to flash.

Right, i've managed to flash Megatron 1.1.2 again, the system ui error is gone.
However, it looks like my power button has failed which would explain why I couldn't turn the tablet on or work with CWM.
I guess I try and flash to stock and contact Asus....

It looks like the power button isn't broken, it just needs to be pressed harder than usual to get the tablet to turn on. I've changed the settings so that the volume rocker wakes the tablet.
Flashed Megatron 1.1.2 then 1.1.3 and we're back in business
Edit: PRAISE ODIN!

Just a quick update, I noticed that my power button was at a slight angle, it looks as though it had slipped and the bit of plastic behind the button was sitting below the actual button on the tablet, meaning that I had to push the button harder to turn it on (if that makes sense).
I got a small bit of blu-tac and pulled the button up, which appears to have reseated it and it's now working as it was before.

Glad to here everything is working again. The question now is why this happened in the first place?
Did you go from 1.0.4 to 1.1.3? I am on 1.1.3 with no issues but as said in the Megatron thread, you have to fully wipe coming from 1.0.4 plus 1.1.2 has to be installed before installing the 1.1.3 update.

I don't know, I was on 1.1.2 and installed the 1.1.3 update then when I rebooted I started to get the UI error. That's really the only problem that I had with Megatron, it would have been easily fixed by just wiping and reinstalling.
It was just at that point that my power button started to play up which confused the issue.

Tablet misbehaving, powered off, but not back on

I was watching netflix, and the interface was acting up, acting laggy, so I powered down the unit to restart it. It powered off, then when I tried to turn it back on, nothing happened. The screen stays black and it just vibrates after 10 sec.
Things I have tried:
Press reset button in hole for 10+ sec, also for less than 2 sec (click it) - no reaction
Press power and hold for 10+ sec - vibrates, like it's starting up, but nothing else
Press power and vol down (also vol up) - same vibration at 10 sec, but nothing else
Had a full charge when this happened, I had just pulled it & the dock off the charger.
When I plug the charger in, I get a solid green light.
Rooted on stock rom with original locked bootloader.
Hoping I can get this thing back on. I'd rather not send the tablet out to anyone or return it with it still full of apps and data.
Edit: Also, when connected to my PC, I get a "USB device has malfunctioned and is not recognized"... oh boy, that doesn't sound good at all.
Edit 2: I don't know if it's pertinent, but the last thing I did before resetting the tablet was adjust Volume+ from 8 to 10. "MusicFX" crashed shortly after that, and the volume didn't actually go up. That combined with the laggy netflix interface is why I reset it. Previously, I've only been skyping and using snes emulators off the market, and browsing the net. I can't imagine why this happened.

I know that when I used to turn off my tablet it would turn off and not vibrate. It was still running with the screen off son I had to hold the button till it vibrated then held it down again. It seems you already tried that but try it out again. Also make sure its completely off. When you connect it to computer it should not see anything if its off.

Thank you for your suggestion, it did not work; it just vibrated both times. I reconnected the keyboard dock and plugged it in via the dock to see if that had any effect, and all the same it is shown as an unrecognized usb device, which in my experience means the usb device has a hardware failure. An Asus support rep has suggested that it would need warranty service. Fortunately I'm still within my return period to BBY, so I will exchange it with them. Just don't like the idea of leaving my unprotected email and other accounts open to anyone who might be able to repair it and get it running again without erasing it.

Find out vendor ID and and device ID of this unknown device. If it is 0955:7030, your device is in APX mode (check if the volume-up button is stuck).

It's just not coming back. I decided to go ahead and exchange it. I'll have to change a crap ton of passwords now, but whatevs. I wish I had an idea of what killed it though.
The vol button was not stuck, it had a definite click 'action' to it on both sides. Wish I had seen your post a half hour ago.
Edit: Wait -- I just crawled through the event logs: Driver Management concluded the process to install driver NULL Driver for Device Instance ID USB\VID_0955&PID_7030\5&250F0A09&0&5 with the following status: 0xe0000203.
Is there a way to get it out of APX mode??

Usually, not pressing Volume-up while powering on is enough.
I'd say your tablet is really defective.

can not boot

One day I went to use my tablet after a long time not using it. It was on the stock OS. And it stops at the Asus screen with the spinning circle I know sometimes this might take awhile so I let it sit for 24 hours and it still is there. I tried cold boot and reset to default and also the recovery image. With the recovery image I get a dead droid with a red ! above him. When I plug it into my computer I hear my computer detect it but I can't access it.

Guessing the OS is corrupted. Bring it back to stock again using easyflasher. You will lose all data by doing this.

You need to be in apx mode to use easyflasher. Press power and volume up for a few seconds and connect to PC. Your tablet should be recognized however the screen will stay black. Then you can use easyflasher. Good luck! Also, try to never allow the battery to go completely flat. If you will not be using it for a while power off.

it is not letting me go into apx mode. When I try turning it off it restarts and goes to the boot screen and freezes there. Is the recovery image on the SD card? I can get to the recovery so I might just put the stock zip on it and try it.

I just tried updating it and I keep getting the same dead droid and it keeps rebooting when I try to power it off so I cant enter apx

Try holding POWER and VOL UP and it should enter APX even if it isn't off first.

No matter what I try and how many times I try when I push the power button it just restarts. if I hold the Power and Volume up it restarts and sticks at the Asus screen. In the Device Manager for a description for the tablet it says "This device cannot start. (Code 10)"

I had that error and it was a bad USB cable. My cable still worked with the stock charger, just not for USB (MTP/APX/ADB)

I do have 2 cables and last time I used then both did work so I know that is not a part of my problem.

You won't see anything in APX mode and may think the device is powered off. So connect it to your computer first, then try to go in APX. You should hear the computer detect the device.

I know how to get into apx mode. I have used it several times before but it will not let me. No matter what I try it keeps rebooting.

Does it still reboot when you try entering APX mode if the USB cable is disconnected from the tablet ?

yes it reboots if it is hooked to the computer or all by itself. If I try to enter apx by itself or hooked to the computer it still reboots.

If I can't get into apx does that mean that I have a brick?

Possibly, or your power / volume buttons aren't working properly / getting stuck pressed in
Might be worth taking it apart and disconnecting the battery for a while / checking buttons are working without the plastic bezel over the top of them
Check no cables have come loose causing weird behaviour

I opened it up cleaned the buttons unplugged the battery and looked for loose cables. Plugged the battery back in and rechecked for loose cables. I tried going into APX and that is a no go. I have not reassembled the unit back together yet.

So what should I do next?

I got it fixed!
I unplugged the battery plugged it back in, did a cold boot then enter apx mode

Must have been some weird bug in memory that was being kept alive by the battery

Black Screen, Green Power LED, APX with USB connect to PC?

So, I am in new territory here. My tf300t suddenly stopped working. I had previous unlocked the tablet (years back) but never installed a custom rom. It was working fine for a few years and I factory wiped along the way a couple times. So a couple months ago I did a factory reset again and it seemed fine for a few weeks. Yesterday I picked it up and I can't get it to turn on. Here are the symptoms:
It will charge and shows a green LED
Can only get a Black screen and will not boot, no ASUS screen or anything
I tried holding power for 30 seconds
I tried holding power and volume down for 30 seconds
I tried the tiny reset hole with a paper clip and the same with power button
When I connect to my computer with a USB it shows up as APX on Windows 10
Is it just dead now? Bricked? Thanks for any insight! Seems strange but maybe it decided to die.

I have no idea what happened to your tablet. If I were in your boots, I would install "Minimal ADB & Fastboot" from here: http://freeandroidroot.com/download-minimal-adb-and-fastboot-all-versions/. Then please check whether the USB driver are installed or not. If not get them here: https://androidmtk.com/download-asus-usb-drivers.
Connect your tablet via USB with your PC. The devise manager should show "Android Phone" => ASUS Composite ADB Interface and "Portable Devices" => TF300
After that seen you have access via ADB to your tablet. Then please flash the latest Asus firmware update to get your tablet on a clean stock rom. For assistance please search the forum. Good luck!

Cenovo mini pc 2 bios reset

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
Click to expand...
Click to collapse
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!
