I wanted to upgrade my Android phone (Acer Liquid Ferrari) from 2.2 to 2.3 but it crashed => I can't turn on my phone,
When I do a clean boot (power + vol up + vol down) there are no problem but my phone doesn't reboot
When I want to go into Recovery (power + vol up + cam) there are an error on the checksum
Partition: checksum splash: chsum =00000000 OK boot:chcksum=8fa17e51 != 0021fde4 **fail** recovery:chsum =00000000 OK system:chsum =00000000 OK ===== <<FAIL>>
So when I want to do
adb devices I have
error device not found. The driver is correctly installed on my computer
How can I launch the recovery mode ?
