Rooting Tab Ultra - Page 7

Renate · 12-19-2022, 09:12 AM

Do I have this straight?

ottischwenk & rexbanner own Ultra Tabs, it's Android 11 and are getting ~18 minutes on 26,000?
ottischwenk owns a Leaf2, it's Andorid 11 and gets < 1 second on 26,000?

I still think that there's some variability here because something was getting ~20 seconds.

ext4 never got case sensitivity option until kernel 5.something, which is why that isn't used.

rexbanner finished at 8.000 and my last line shows 8m02.08s at 26.000

no, app 1 second for each additional 1.000 (+- linear)

I got a message from Boox, that I should include time into alpha.sh

Code:

for a in a b c d e f g h i j k l m n o p q r s t u v w x y z
do
date
i=0; while [ $((i)) -lt 1000 ]; do touch $a$i; i=$(($i+1)); done;
time ls -l | wc
done

make the test and deliver the result

This seems similar to the problems I've been having; when I load KOreader on my Nova 2 or Tab Ultra, it takes a huge amount of time to open up the main book folder compared to what it requires on any other device.

The Nova 2 doesn't have this flaw though - it takes 18% of the Tab Ultra time for this test

Sorry, I mean the Nova Air 2. It has the problem, but the Nova Air 1 doesn't.

Its an Android 11 Problem, only Leaf 2 is an exception to this.
Have you already submitted feedback complaints regarding this?

I sent in some feedback mentioning that the device becomes very slow when handling large numbers of files, but I could probably send in a better one if I had a better notion of what to say, just to be sure they're hearing about it from multiple people.

How many books do you have?

That doesn't seem like much to me - besides, mine might be of a different nature.
My file system slows down after a run of Calibre Companion transferring more than 16,000 books

I've been closely following and checking this thread for updates on the ultra on a daily basis, but given the detour(?) into filesystem performance and the silence since, is it reasonable to assume that root is not very likely to be found anytime soon?

If so, it's a shame the graphics performance boost in the ultra over the NA2+ comes at such a high loss of accessability. :/

No, quite the opposite. As mentioned in this thread it can be rooted without a problem. You can easily root it by downloading the boot image in EDL mode and then root it using magisk. I used the loader

Code:

qualcomm/factory/sdm662/0014d0e100000000_d40eee56f3194665_FHPRG.bin

and it worked perfectly fine.
It also works with the newest update which fixes the slow directory loading problem.

GfE · 01-21-2023, 11:33 AM

Yay! That's double good news!
I had not noticed it's actually a success.
Thank you all so much.

Nice, I was worried I'd have to wait for the next firmware release to grab it from the OS.

Would you mind elaborating on the tools and processes used to accomplish this / pointing me toward a primer on that?
