To Update E81 you need the 3GSwup for E81 and as cable DCA-140.

Strange. E81 is not more supported by BenQ:

My chinese Language is bad... So I can't find it anymore.

Here you can find few Versions:

elibom

The latest I know is SVN 52.

Again. Normally BenQ Taiwan offered official E81 Firmware. But they removed.

WARNING!
You have to identify FK or PK before you update.

1.
*#06#

SW Build to identify Firmware:
Example: MerB1A_0.52 is SVN 52

2.
*#0606#

Shows if Net Locks are set... If process failure

3.
I have only seen Prototype/Sample E81. NEVER the Retail Version...

Samples have only Samsung NAND (64 MB).
I have no infos. What Retail Version has...

4.
For Fieldtest Key Firmware. The highest Version I have is SVN 47.
But I think all Samples are with unfrozen OTP. So Root Key could be overwrite.

5.
Dead?
How dead is dead?

The deadest dead I know. Is wrong Boot... Bootloader wrong.
Then you need JTAG.

Example EF81

I search JTAG TPs for E81 Sample and Retail.
Maybe someone has the schematics or any Documents about E81.
