Fastboot : HOW TOs

____________________________________________________________________________________________________________________________________________________

i want to write the topic as "FASTBOOT" but someone was reserved it before ! ____________________________________________________________________________________________________________________________________________________

before anything i want say that my English is not as good as the others so sorry because of my mistakes and if any one edit them I'll really appreciate it _____________________________________________________________________________________________________________________________________________________

i found that for entering into fastboot from android you should go to terminal(termux or terminal emulator or ....) and type : reboot bootloader or from pc with adb on: adb reboot bootloader or adb shell reboot bootloader after that the device will reboot and stuck on its bootlogo(manufacturer logo) it means that fastboot mode enabled or in some cases in will show a red fastboot text on black screen for using fastboot on many sunxi devices you shoud use fastboot -i {vid(vendor id)}  i think sunxi vendor id is 0x1f3a so you shoud write: fastboot -i 0x1f3a 

example : fastboot -i 0x1f3a reboot __________________________________________________________________________________________________________________________________________________

now some useful commands:

for continuing default boot(and exiting fastboot): fastboot -i 0x1f3a continue for rebooting the device into default mode: fastboot -i 0x1f3a reboot for rebooting the device into bootloader(in this case fastboot!): fastboot -i 0x1f3a reboot-bootloader or fastboot -i 0x1f3a reboot bootloader for entering efex mode(i think is SUNXIs flash mode! and flashing the dvice using PhoenixSuit or ...): fastboot -i 0x1f3a oem efex for formating whole storage: fastboot -i 0x1f3a oem format ___________________________________________________________________________________________________________________________________________________

you can find other command by typing fastboot 0x1f3a help remember that fastboot(and adb)should be installed on the device that connect the tablet or phone or developing boards ____________________________________________________________________________________________________________________________________________________ WARNING:never reboot the device into fastboot if you don't have a pc or laptop or .... because you can't exit from fastboot with out a pc or ...
