Have you disabled dm-verity ?

Use a USB keyboard over the OTG adapter and hit Escape  on boot (Or DEL, my memory doesnt serve me right now and I dont have it with me). That way you can acces the BIOS

An alternative it to power off your tablet and then turn it on by holding Volume-UP and the power button until it boots into BIOS (the keymap on the bottom right are also touch buttons… so if you want to go back a menu, tap on the ESC/Right Click : Exit  option on the bottom right)

Once there…  Go to Advanced-> System component  , and Enable “MS Custom sdbus Driver”  , then save end exit your BIOS. That should enable your SD Card in Windows

Does it turn on?

If you re confident with soldering… you can pop it open and desolder the battery cables. I havent seen a BIOS battery on it, so I guess if you remove the battery for a couple of hours it will reset.

Of course only do that if you re confident on your soldering skills, and you do it at your own risk. You can easily damage your tablet or your battery.

(And it goes without saying that if you do a bad connection and something short-circuits, your battery might explode)

Can you explain a little more about your problem so we can understand?

Have you tried to boot to BIOS using a USB Keyboard? The tablet from what I ve seen in my own experiments, resets the BIOS settings automatically when you change something and it cant boot (kind of like the overclocking protection that some motherboard BIOSes have)

[Thanasis]

Could you post the exact model ?

I managed to get my 64GB SD card to be usable by windows.

Until recently, it was not working on my tablet (I got an exclamation mark with Error 10 in device manager).

I recently decided to divide it in 2 parts (make a second partition for Link2SD in android) so I divided it in 2 primary partitions over MBR. One as exFat and one as ext2. Out of curiosity I booted back to Windows, and again no luck (still the error 10) . But since I wanted to check some files on it, I used an external card reader to read the SD Card.  After having finished, I put the card back into the tf card slot, and I noticed I could still see it.

I dont know if its just pure luck (that 1 in 10 times it works that people have mentioned happening), I dont know if connecting it to an external adapter initialized some variable that could not initialize by the TF adapter, or any Windows voodoo like that, or it was just a windows update running at the same time that updated the driver, but for the last couple of hours (and 3-4 restarts) I have a working 64GB Sdcard , that refused to work in the past.

I ll let you know if it stops working

 

 

Disregard all that… Stopped working after half an hour.

wow I was on android and battery went down to 10% and while I was charging it, it sort of died, black screen. After all that effort getting windows updated and stuff. pfft.

–update–
the hdmi connection finally started working after trying few hours to turn it on. the touch on tablet is also working, just the tablet screen is not showing. still black screened after almost a week. have sent an email to banggood, anyone know what are the options available?

Have you tried looking inside in case its just a moved cable or something?
Usually for screens to go black, its either the power cable to the screen power PCB, the screen cable itself, or the power PCB being fried. First 2 are easily fixable and the third not really. If you want help opening your tablet let me know. I haven’t noticed anything that would show if you popped the back cover to take a look, but I cant really promise you that there s nothing, so do at your own risk.

Are you sure the BIOS setting is still on?
I ve noticed that sometimes when my Tablet fails to boot, the BIOS resets (I guess its a similar option desktop PC’s have to protect from overclocking failure).
More than a few times I had to set the settings in my BIOS and boot properly for them to stay set.
Other than that…my Cube that the issue most CherryTrails have with the SD card adapter not being able to see some SD Cards. My 16GB Kingston works great, but my 64GB Adata crashes it.

So… in order to get a working custom boot image, you unpack it, make the changes to default.prop and init.rc and repack right?

Software Distribution is a new way for Microsoft to pass on the Update files. When you have software distribution on in your settings, it saves all your downloaded update install files, and uses P2P to send them to other people. On my case, apart from the oversized Winsxs , I had a huge SoftwareDistribution folder as well.
There s a way to turn it off, but since in my case it had already taken up so much space, I just deleted the folder and moved on with the Instalation

[Thanasis]

I ve managed to use a Teclast X98 Pro recovery on my iWork8 Ultimate and got it to root (but it killed my WiFi)

I ll try to port it for Cubes

From another post of mine:

I managed to install the 1511 update after alot of tries, so I hope this works for you as well (do at your own risk)

First of all make sure you have full battery as the update most likely will drain it and might fail.
Connect either a big TF card, or a USB stick with lots of storage (32GB preffered)

When the update starts, it tells you there is not enough space, and asks if you want to use external storage with 10GB free.

Choose that option and click on Refresh. You ll get a message telling you that you need an extra XXX amount on your internal storage (which you most likely dont have yet even after you ve tried Disk Cleanup)
The most space on the partition is taken by the Windows folder, and in particular Winsxs folder and the SoftwareDistribution folder.
1. First thing to try is to delete the SoftwareDistribution folder(It saved me 3GB of space). That should give you enough room to start the install

2. If it fails, next step is to dissable the Virtual Memory.
* Go to System->Advanced Settings->Advanced->Performance->Advanced->Change
* Uncheck the “Automatically manage paging file size for all drives then click on “No Paging File” and click on Set
*Reboot
(this should probably save you another GB of space)

3. If you still dont have enough space, we ll try to use a method back from the early 2000’s
Right click on your c: drive -> Properties and on the General Tab click on “Compress this drive to save disk space” and click Apply

Those should probably be enough to get the install going

ps. To save time from downloading the update all the time, this trick might save you a little effort. Once the update is downloaded , and it has started , you ll se a hidden folder (enable view of hidden files and folders and protected OS files) called $Windows-BT or something similar which should be around 3.5GB.
Copy that folder to your TF card or USB stick , and instead of starting the update from Windows Update, simply go to that saved folder and click on Setup. The update will start

I actually managed to root the tablet by using a custom Teclast X98 TWRP image, but it killed my wifi. I had to reinstall the stock rom to get WiFi back.
Now I just have to properly port that ROM to our good old Cube…
