Allright so I'm back here to report that 1 year later I tried these recommendations. timjcarter thanks again for the guide! However...
I have following things to note/complement to guide:
- for rooting the files have to be placed in root directory and if there is an error in flashing, the file has to be downloaded and copied again (preferably from a mirror)
- for formatting the sd card it should be as a primary partition I guess (as said other guide), not sure if it would change anything including the fact that my winXP laptop which I used to partition the card (in its card slot) later stopped recognizing it (suggests reformatting), though other winxp laptop sees it, no logic lol
- also ext3 is probably best choice for 2nd partition which is advised not to exceed 1gb (fat32 is advised for lager partition not referring to overall card size from what I read)
- before next step we get onto significant problem: google play can be installed by arctools and these are paid now, there was no clue in the appslib store app how to connect the account with paypal ...anyway I didnt bother and found apk file to download:http://www.arctablet.com/blog/wp-content/uploads/2010/12/com.arctablet.arctools.apk
(i did reformat whole device also after firmware flashing, considered it reasonable so it was clean)
- the sd speed increase app seems not to keep the setting after first reboot, as set, but later it was ok
- link2sd has 2 options for moving/linking apps that make some confusion: "link2SD" and "APP2SD" - difference is the last one is native android option, seems to move simply to default sd partition and perhaps not always all data so "link2sd" should be better choice
- the arctools app should not be linked/moved to sd as it stops working
Also I did the mistake of downloading standard apps (gmail, maps, some other unneeded as it turned out) through arctools and they are listed as system apps ...but i see now I can deletem them from link2sd. Anyway I have now ~220mb of system memory and about ~80mb of ram
BUT...I don't know if it was worth the hasle.
Unfortunately to me the words "flying" or "lightning fast" seem to be far from appropriate for this sluggish tablet...it still feels quite slow! I think now it is just properly set so it will not get worse and worse with time... the card was some more expensive available in the store: ADATA 16gb some 16class or sth (in the working tablet at the moment)
Not expecting some iphone or top notch todays device performance but something closer to single core android phone like for example my GF's xperia mini proDid anyone try swap partition if it works on gen8 or makes noticable difference ?
something liek this maybe:http://forum.xda-developers.com/showthread.php?t=1659231
