No boot

Hello,
I've a B1-730HD with Intel.
It doesn't boot.
If I connect it to charger or try to press Power button it only flashes the USB logo with the white bar for about 1/2 second.
If I connect it to USB port it will show up the same USB logo but after a while the bar changes to red.
If I try to press Power button + volume up, it freezes with Intel inside logo.
It must got some software problem as it was only updating apps from playstore but I think it run out of storage.
I'm now downloading the firmware from acer website but I'm sure as I can't open the android reset menu I'll not be able to load the firmware from mSD.
So I'm hopping the V1.0 or 2.1 Acer B1-730HD Repair Tool can help, but I'm not being able to download it from anyware.
Can you provide a new link and comment some procedure to correct recover the firmware?
Regards.

When I get home at my PC I can upload all of it.
Are you home yet? 😥 I tried looking for repair tool but all links are dead, tried temporary recovery from here and it keeps saying DEVICE STATUS: UNKNOWN. It's stuck to intel inside logo and does nothing else, no acer logo, no recovery. I need any possible method to repair, be it safe or not, it cannot get much worse than this. I really want to use this tablet again because of a x86 cpu.
It might also help if you have a flash.xml or flash.json of any intel device (I cannot even find those), then I could maybe make my own...

I don't even have a motor in my truck yet to go home, resealing and putting a lower miles one in it at a friend's house in another town. Did you try to do this in Linux yet? Almost always will work. What does lsusb say? If you are in Windows and refuse to use Linux, what does Device Manager pick up? I did forget to check last time I was at my house though, sorry about that.

I'm not very familiar with linux but I quickly booted up linux mint in virtualbox and the tablet shows up for about 3 seconds as "Intel Corp. CLOVERVIEW", from when I plug it in until intel inside logo shows up (similar behavior to what happens in intel platform flash tool on windows). But now I have no idea what to do next. Thank you for your help, I will be patient no matter how long it takes.

Here is a folder with the files you should need. I compressed it with .tar.xz so you will have to use 7-zip to uncompress on Windows.

Sorry for late reply, I didn't have the tablet with me for a while. I have a problem, intel flash tool says system.img is missing from what you gave me, but the update file I got from acer doesn't have system.img either, system is simply a folder (image 1 - root of update.zip, image 2 - system folder).

What I have tried: I edited flash.xml to not include system.img (thinking I could simply go to recovery and update from there).
Attempting to both boot and go into recovery has the same result: intel logo then a flashing empty battery icon (there is some progress!!!!). Battery does hold charge so I doubt the battery itself is a problem, but I have no way of confirming that.

So it boils down to one of these:
1. How do I get system.img file? Is it possible to create one out of update.zip?
2. Can I just flash update.zip through intel flash tool?
3. Is it all just a faulty battery?

Edit:
I left tablet to charge for around a hour and it finally somewhat booted up. Flash failed to complete, but I got to the droidboot screen and from there tablet wouldnt boot into recovery or accept fastboot commands. So I installed fastboot drivers, tried to flash again and now all I see is a usb logo 😥. Flashing makes it turn into intel logo and then it just gets stuck there, force rebooting makes it go back to usb icon. None of this makes any sense 😥😥😥, even uninstalling fastboot drivers keeps it the same. Why it cannot even boot to droidboot anymore????

    Today I had some time and I decided to create a small application for a screenshot. Always makes me annoyed press power and vol + and etc., to make a screenshot, because I made an application that make screensot when shaking up&down the device, and when I want a screenshot simple just shaking ;). Maybe someone will be needed so I decided to share it.*

    Application to work need android 4.0+, ROOT and BUSYBOX!!!
    Screenshot will be saved on /sdcard/Shakeshot .
    For all questions, download and others stuff please contact me and follow on www.android-tech.rocks thanks.

    3g dongles / umts modem / internet surfsticks.... Work!! USB OTG (directly!)

    after some failed attempts with ppp widget 2, involving different 3g dongles and a powered hub i finally got 3g working!

    i used PPP WIDGET 1 with the classic 3g dongle: an old Huawei E160, and a newer model : E173u
    (most newer Huawei should work too! ) no hub was needed!

    the Huawei modems have a built in emulated driver cd for Windows and that's why the need additional software to be switched from cd mode to modem mode, our tablet / Android however doesn't recognize the cd filesystem and says "damaged usb storage"... which is no problem, it's normal!

    the automatic recognition of the new ppp widget 2 failed, but the older widget 1 has a manual mode: select manually choose device!

    how to set up ppp widget 1 on B1-730hd :

    1. get ppp widget1 from playstore (free)
    2. put the widget on a startscreen (necessary before plugging the dongle!)
    3. plug the modem in... wait for the "damaged usb storage notification"
    4. the system asks which app to use as a standard.... select ppp widget1
    5. disconnect device
    6. go to configuration button (of widget)
    7. enter apn, username & password
    7b. depending on your sim & carrier : enter pin code if you use that and enter ip and port of needed (if it failes to connect with "connect script error" you need it) (i had also to enter ip adress : port to get it running)
    8. select manual device selection (tap on icon mode)
    9. close settings and plug in device
    10. tap on the icon (left ppp symbol on the widget) and chose your modem: Huawei xyz...
    11. see if the status led changes blinking color (from green to blue) = pin unlocked, network ready
    12. the connect button is not longer greyed out... click it.... and wait

    if the led stops blinking dark blue and turns light blue (permanently) you made it!
    if not : open configuration and see LOG, most likely your apn, name, pwd, ip etc are wrong....

    have fun with direct access to 3g on the tablet - no need to wifi or Bluetooth tether anymore if you own am old Huawei E160 (more modems should work, but i haven't tried) (no powered hub needed, but use one of you want to save battery...)
    working devices :

    Huawei E173u (7Mbit max., Dual antennas, balanced against interferences) i recommend this, good signal and fast...
    Huawei E160, (3,6Mbit, single antenna and sometimes bad signal) use it if you own one, but buy the E173u instead (signal boost, interference minimization, good signal)
    4
    calm down people, we don't need this to live or make money... but sometimes we need some help to help, Happy 2015 to everybody!
    Very thanks to @vampir74 & @social-design-concepts, happy new year to you guys!
