    How did you manage to upgrade to 1703, how did you get 10GB of space? does your tablet is a Windows only system? Thanks

    Yes, I removed Android. Another way would be to download the installation files through Microsofts Media Creation tool and put it onto an SD card or USB Stick. Then start the update manually from there.

    Sorry, that I don’t have an idea, what to do.
    I got the 1709 update (Fall Creators Update) and everything seems to run well, except a slightly increased battery drain.

    Does it work power and volume buttons on 1703 for you guys?

    Yes, but at the first starts, it took a while for reaction to the power button. Windows seemingly was still on sorting out something.

    I tried the update again today and it seems that it ran through smoothly and everything is working.

    Move the partition around. If a partition can’t be moved, copy it and delete the original partition as described here:

    If you are unsure, what you’re doing, read through documents on how UEFI works…

    Get an externally powered USB-hub and connect Keyboard, mouse, and USB-stick to it. Then boot the tablet. By the way, it just accepts 32bit boot loaders…

    I wrote a manual, how to remove the Android part here:

    https://techtablets.com/forum/topic/how-to-delete-android-partition-and-merge-it-with-windows/#post-47339

    If you don’t delete but just resize the Android partitions it might also work. But I don’t know, how Android reacts if some of its partitions are suddenly smaller…

    I explained, how I removed the Android part. Maybe it helps…

    I just made a partition copy sector by sector. So the file system (if there was any) remained the same.

    I also made the update using an USB Stick and it worked quite well. The only thing was that I had to reinstall the audio driver from the driver pack here. The automatic search for drivers just found one for the hardware but inappropriate for the system. ??? What does that mean??? Well the driver from the 200MB driver pack installed flawlessly.

    Hi All,

    yesterday I removed Android successfully from my Hi8 Pro. Here is what I did:

    • Install the free version of “Macrium Reflect” (http://www.macrium.com/reflectfree.aspx) for backing up the system drive and “MiniTool Partition Wizard” (https://www.partitionwizard.com/free-partition-manager.html) to work on the partitions.
    • Make a full backup of the system drive using “Macrium Reflect”. Be sure to activate verify.
    • Let Macrium Reflect make a rescue USB-stick using Windows PE10. This requires a 400MB-download from Microsoft.
    • Make sure, the rescue USB-stick works: attach it to a USB-hub attached to the tablet together with a mouse and a keyboard (and an SD-card reader) and reboot the tablet. Press the delete or escape key until you get the BIOS screen. Go to the last tab and choose to override the boot sequence to boot from the USB-stick. The reason for the external card reader is that the internal card reader will not be recognized by Win PE in the rescue environment. Browse to the backup and check if it can be accessed.
    • Now leave the rescue environment (red icon on the lower left) and start the tablet again to windows (press the power button until the tablet starts).
    • With the “Minitool Partition Wizard” delete all partitions on the system Drive except the last four ones, which are: 1.) *:SYSTEM, EFI System Partition, 2.) GPT (Reserved Partition), 3.) C:WINDOWS (GPT data partition), 4.) *:RECOVERY (GPT Recovery Partition).
    • Apply the changes and reeboot. (I’m not sure if you really need this, but I wanted to check, if the BIOS recognizes, that there is just one EFI system partition left.)
    • With the “MiniTool Partition Wizard” move the “EFI Sytsem Partition” to the very beginning of the drive. Apply the changes and reboot. (I wanted to make sure, that the BIOS recognizes that the EFI system partition changed its position.)
    • Now the part which made me quite nervous: you can’t move the 16MB-partition in front of the Windows-partition with the “Partition Wizard”, so you also can’t expand the Windows-partition (the main reason for all this). I read that Windows would need this partition for some drive management. Therefore I used “Partition Wizard” to make a copy of it right to the beginning of the unallocated space directly behind the “EFI System partition”. The new partition is not “reserved” anymore but a normal GPT data partition. Then I deleted the reserved partition in front of the Windows-partition.
    • Reboot. (Contrary to my expectations everything worked fine and Windows came up without a hassle.)
    • With the “MiniTool Partition Wizard” resize (‘Extend’ doesn’t work) the Windows-partition into the full unallocated space in front of the Windows-partition. Click to ‘Apply’ and “Partition Wizard” tells you to reboot in order to make the changes as the partition in question is the current system partition. Reboot.
    • After a short while in the pre-boot environment, where “MiniTool Partition Wizard” resizes the Windows-partition, Windows should start up.
    • Finished (more or less).

    I noticed that somehow more space was used on the C: drive then before resizing. Cleaning up the drive fixed it to a certain amount. Then I noticed, that my virus scanner (Avira) didn’t work anymore so I had to remove it completely and reinstall.

    I hope, my experiences and this guide help those who are interested in the same topic.

    If you are worried about deleting the first EFI System partition (*:ANDROIDIA) and afraid of your tablet not booting anymore I suggest these two articles on how UEFI boots up operating systems:

    Can you also switch the audio channels? You might have noticed, that on the Hi8 Pro left and right channels are swapped…

    I bought the tablet from geekbuying and I must say, that the people there were very helpful.

    1) Approximate amount you paid to send it back

    From Germany 6.80€ as a ‘Großbrief’ and ‘Einschreiben’ for a tracking number through ‘Deutsche Post’ –> DHL. I sent in just the tablet in lots of cushioning, no additional accessories. GeekBuying sent it then to Chuwi for repair.
    2) Did you return it for a refund?

    No
    3) Did you send it back for repairs?

    Yes
    4) Does anyone have positive experience with repairs (everything works perfect after it’s back from round trip to China)?

    It took quite a long time, but about two months later I got it back repaired. I sent in a dead Windows 10 only tablet and got back a dual boot tablet. The serial number is the same, but somehow the charging LED got a lot brighter. Maybe the electronics got changed… (Now I’m trying to get rid of Android…)

    The bad thing is that now there are some scratches on the display. The technicians at Chuwi should better clean their workbench…
    5) Do you have any additional advice for owners of dead tablets that won’t even charge?

    Send it in for repair.
