OK I have figured it out and have had system.img in hand. Its 1.5GB in size, almost double kitkat!
[General Questions and Answers] ash2k5:
Uncompressed system.img of KitKat is also 1.5gb, i think its actually total size of system partition (1.5 Gb).

This is the largest one i have seen, my phone has ~600mb system partition.

If you remove bloatware 500 mb would be enough even for lollipop.

I thought of decreasing system partition size, but am afraid that i may brick.

Help please...

Hello,

First, deep respect for the ease of tool developed....

I tried to flash my Acer, currently on Kitkat, and I try to root to make use of the external SD-Card....

With the tablet connected via USB (in developer mode), with the system image on the external SD-Card (FAT), I start the PC-Tool.

However, it starts building, though the progress is stucked at 5%.

Any hint/tip please ?

Regards, Frewald

You install orig USB drivers from Acer!?

[General Questions and Answers] frewald:
My tablet screen just showed the normal homescreen.

Upon USB connection it gives a push-message that it's connected (and of course it starts charging), that's all....

(normal tablet USB connection MTP, so not Camera PTP, not in developer mode)

I de-installed all USB drivers, re-installed default per Windows (Windows 8.1 64b drivers), same non-behaveour....

Now I try to install the default Acer USB package, which does not allow to install automatically as all unsigned....

When using the Windows manual driver install menu, using the official Acer USB package for this tablet,

the three choices I get are Android ADB Interface, Bootloader Interface or Compisite ADB Interface.

I've no idea what to do, have the feeling I'm on a dead track......

Please help.... Tx

Go in developer option and turn on USB debugging

Sent from my B1-730HD
[General Questions and Answers] frewald:
Ok, tried it, below some results (device messages translated from Dutch into English, so not 100% accurate)

1. de-installed all (hidden) devices from Windows Device Manager

2. put Android in USB Developer Mode, than enabled USB debug tracking

3. connected USB cable between Android and PC

4. Android tells connected as media-device

5. Windows device manager shows both the B1-730HD under portable device AND a MTP device under Other-devices

6. Now I start your repair tool (this starts showing 1% progress, than a message about daemon tools starting up, instanteneous jump to 5%, and than it remains there for over 15 minutes, till I give up).

I'll perform a factory reset to the device, maybe that helps, than restart the complete sequence.... Ok ?

[General Questions and Answers] frewald:
We did it !! Thanks for the contineous quick support.

I had to de-install the ADB drivers, and re-install it. I did it both per Google SDK Adb drivers and per Acer's. Perhaps a bit overdone, though it seems one out of them was the key-ingredient. It rebooted, and after a few seconds I saw both the tablet re-booting and the Windows progress indicator increasing....

I'm really glad, now I can use the potential of the external SD-Card (again)......

It seems to be having an issue whenever I turn off the device and connect it. It's trying to install a driver for a device just called 'Android' and it won't accept the drivers from Acer's site in any way I try, .inf, running the drvinstall.exe or anything.
