Edit
Solved for HD
links from tech Rocks working, firewall bloks google drive

But, stucked @ 11%, no go further

Edit 2:

OEM partinioning failure.

Yeah, the locked bootloader and the rest of the design is kinda a problem. I have the HD version, which is vespa, I'm not sure what the product name is on the non-HD version. I just do every reflashing step manually using fastboot, Although I use Linux, so your results may vary, But I noticed some wierd behavior after restoring my tablet last time: The accellerometer does not work, Xposed does not work (No Module effects after reboot), And the tablet sometimes quickly goes down to 0% battery while sleeping. I'm a geek at this stumped, but I am still stumped, maybe I'm trying too hard to try to unlock the bootloader. :laugh:

Thank you
Rom from Tech Rocks and Vespa are different. You want to say that they are both for HD ver? Is there any special way to flash that service rom?
I also manually flash boot parts via fastboot (recovery, boot, system, from TechRockn rom), but it solves nothing. After restart, just stuck at logo...

Try flashing IFWI and DNX.

 

[Boki_Srb]

Try flashing IFWI and DNX.

I tried all combinations...IFWI, DNX, DOM parts....independent and combined

Hmmm, make a video of the situation and put it on youtube, I'm kinda stumped here......

Sorry for late reply
No need for video
I started IPFT in advanced mode, then you can flash separate sections. Bootloader, recovery...or only rom image, or... I tried several combos, always same problem. I find it very suspicious that what I try do ordinary factory reset, can not. Some errors about partition.
I definitely think that the chip is defective.
If anyone know some magic...suggestions welcome.

Open up the tablet, take a good photo of the PCB, We'll see if there is a UART port. (Usually just pads)

 

[Boki_Srb]

Uh, I put it deeply in defective electronic box
PCB is. .. ridiculous. Small, almost nothing on it, chipset is fully shielded. No place to connect anything to it, no reset button, nothing.

Definitely the main chip is problem, because I can not format it or do anything with it.
Communication is ok, software send command to tablet, but can not be executed. Default try timeout is 180sec, and after that, procedure is abandoned.
Thanks for everyone's effort

Oh wait, I thought I was on the generic Intel device thread, but since you have the B1-730HD too, I know where the serial port is. Do you have a USB to TTL serial adapter?

 

[Boki_Srb]

... Do you have a USB to TTL serial adapter?

No, unfortunately

Recently, my B1-730HD started to act like Boki_Srb says, so i was thinking i you could tell me what can i do with a USB to TTL serial adapter, or direct me to a tuto how to use it and give me directions about the procedure on the tablet. Thank you.

That tablet isn't even closely related to the Acer Iconia One 7 B1-730/B1-730HD tablet, which this thread is about, that B1-790 has a Mediatek garbage chipset, whereas the B1-730/B1-730HD tablet has an Intel chipset. The Mediatek chipsets are a pain to develop for anyways, so you're out of luck.

You have to use the serial console to fix it. I should make a thread about it.

I'll be waiting for your thread, hope you can help me. It looks like a nice tab if it is working.

I may have to buy a new one because on my current one, the kickback protection diode went bad and let current flow both ways, so it short circuited the backlight driver and now the backlight doesn't work.
