Please help!
I tried to update the bootloader to v9 but after installing the zip file thru cwm, rebooted it said flashing failed and black screen.
I can only get to APX mode.
When I use the blackthund3r_A500_APX_Flash_Tool to flash, it did not detect the APX mode but I can see the APX device from windows. The process hang in EBT stage 2 - uploading image.
So I tried to nvflash. I can enter the nvflash mode ok:
C:\Android\A500\V8-UNL-ICS-HC-bootloader-MULTI-cwm>nvflash --bct bct.bct --setbct --sbk xxxxx xxxxx xxxxx xxxxx--configfile flash.cfg --bl bootloader_apx.bin --go

Succesfully updated partition table information to ptable.txt

When I try to format partition 4, it failed:
