Hi all,

As the above guide might not be detailed enough, here's a new guide for flashing the B1-710 firmware with SPFT (based on the Flash Full ROM guide (for unbricking) for A1-81x thread):

Download and unpack drivers: http://bit.ly/1hujx8o

Run "install_driver.exe" AS ADMINISTRATOR and wait about 2 minutes. After

this you will see a popup window (Driver for xxx installed), close it and

reboot your PC.

Turn your tablet off and connect it to PC. You will see a popup message

"New device detected". Wait until drivers will be installed OR until tab

will disconnect from PC.

Download the firmware for your device. Unpack the "firmware" archive to

your folder.

Download the SP Flash Tool for your B1-710:

http://bit.ly/1XNEp8U. Unpack the "SPFT" archive to your folder.

TROUBLESHOOTING AND SPFT ERRORS:

SPFT Error "??(2)": Reboot your PC and retry.

SPFT Error #10*3: Reinstall driver, try another USB port.

SPFT Error #1021 (#8045): Your tab is completely dead. Nothing can revive

it.

SPFT Error #2004: The most dangerous and common error. See "Fixing reconnecting" below.

SPFT Error #3144: This error may be on B1 tablets. For fixing it you need to remove back cover.

When red bar will reach 100%, wait about 1 second and disconnect the battery. But if it will not help, you need to use testpoint.

SPFT Error #4001: Disconnect tab's battery and retry without it.

SPFT Error #4010 (#4032): The problem is on PC side. Try to reinstall driver, use another USB port and cable. The most users who got this problem has solved it by using another PC. Try to Disable signature enforcement if you're on Windows 8 / 8.1

SPFT Error #61**: You will get this error when you have unlocked your bootloader and trying to flash.

Solution: in SPFT UNcheck all blocks except PRELOADER, flash it using

"Download" button.

Then flash ALL blocks EXCEPT PRELOADER using "Download" button.

SPFT Error #8038: Flash using "Download" button.

Fixing reconnecting:

When you connect your tab to PC, it recognizes tab. But after few seconds

tab starts to reconnect every 3-5 seconds. Only two solutions are available

at the moment:

1. Disconnect tab from PC, press Reset button (located in the small hole)

THREE TIMES and try to flash again.

2. Try to flash without battery. Stuck on "Searching..." in SPFT:

See SPFT Error #4032.

Stuck on Acer logo: Press "Reset" and turn tab on again.
