A210 - Bricks - Help!

Hi.
I have a problem with brick Acer Iconia A210.
It is hang on acer logo and in left top corner is: bootloader version ISC-MR1-b05547a (unlock mode)
I can;'t communicates with tablet via USB (no device found) even I can't get to recover mode by fallow this instruction:
-----------------------------------------------------------------------------------------------------------------------
Start tablet in recovery:
1. Tablet is off
2. Press VOL-(**) and Power and hold them
3. When tablet vibrates, leave Power button
4. Hold Vol- (** untill it vibrates a second time (little bit shorter than first time)
5. Switch from Vol-(**) to Vol+(*) when is vibrating msecond time
6. you see "booting into recovery" on your tablet, if you have done this correct.
-------------------------------------------------------------------------------------------------------------------------
Any point is correct except last one, I don't have "booting into recovery" but this same hanging acer logo with info about bootloader version.
Any help how can I go to recovery mode? Or how un-brick my tablet?
Thanks.
