Fitting a 2260 or a 2280 M.2 SSD into Chuwi LapBook 12.3?

Has anyone modded the Chuwi LapBook 12.3 to either remove the M.2 plastic holder on the back plate or cut open one side of it to increase the length of SSD that can be used?

I'm genuinely curious if it's possible to mod and insert a 2280 M.2 SSD, since the options are much more plentiful than 2242's... If it's not too much of a bother, can someone take a picture of the inside of the back plate so we can take a look at how the M.2 "holder" bit is mounted onto the back plate, and if it's easily removable (e.g. screw or whatnot)? Thanks!

The mod with a 2280 M.2 SSD is possible and quite easy:
You have to shorten the metal weight at the bottom to gain the space for a 2280 drive. You need some spacer and a fitting screw to screw on the end of the M.2 device. The plastic piece glued to the metal bottom cover has to be removed to have enough space for the M.2 drive. I added some thermal pad to my SSD as it gets quite hot under load.
I uploaded the fotos to Dropbox as I cannot understand how to do it here (I cannot read chinese).

But so far I did not find out how to boot from the new big SS and not hte old small one. How is this done?

The Dropbox link doesn't work, you likely set it to private so only you can view it. You should be able to attach pictures here using the clipboard icon (or upload them to a picture service like https://imgur.com).

To boot into the new SS, you have to go into the BIOS (keep pressing F7 as you boot up) and change the boot order from the internal eMMC to your SSD.

No, there are no boot options in BIOS "eMMC" or "SSD". After the installation of another Device you get a second Windows Boot Manager. In my case the second one had the device name (a crucial M.2) in brackets. But this did not help me either: Whatever I defined as first boot device, the Lapbook always bootes from the eMMC.
I then simply erased every partition from both SSDs when booting from a 1703 USB stick and simply installed a new Windows. Now I only have to restore the backup I made with AOMEI and Macrium Reflect. With AOMEI I messed it up as I could not choose the System partition only, it wanted to restore all three Windows partitions.
I posted the fotos already on TechTablets: https://techtablets.com/forum/to ... /page/2/#post-71048

The BIOS key for my LapBook 12,3 is *not* F7 but DEL.

But F7 gives indeed a pure Boot device selection.

Did you manage to boot from the new SSD? It's a Crucial, but which model?

It is a CT250MX200SSD4 according to Device Manager. And the Chuwi boots without any problems from this Crucial drive. The built in Toshiba 064G93 eMMC is my data drive now.

The CrystalDiskMark 5.2.2 x64 results for the M.2 are 558/507 62/54 402/393 14/43. Quite good but miserable 4KQ32T1.

Great results, far better than internal eMMC and than every other M.2 2242 drive I've seen.
Can you upload some photos on imgur or other site that needs no registration? I'm not registered to techtablets.
