android fastboot指令 的疑問?
 

fastboot -i 0x0489 flash recovery twrp-recovery-v3.0.2.0_infocus-m372.img

為何我這樣寫到recovery 一開機就到 twrp 的畫面 ???

你開機一直按音量鍵?

我都沒按啊

是每次開機都先到twrp？

是的............

是從此一開機就進TWRP?

還是你只是用這指令後會這樣?

原說明
1. Boot to bootloader mode
-> adb reboot bootloader
-> hold the vol down + power key at power off
2. fastboot -i 0x0489 boot twrp-recovery-v3.0.2.0_infocus-m372.img
(just boot to TWRP Recovery, without flash image into device)

3. key-in the below command(by PC) in the TWRP recovery mode
adb push twrp-recovery-v3.0.2.0_infocus-m372.img of=/tmp/rec.img
adb shell dd if=/tmp/rec.img of=/dev/block/mmcblk0p29
(Flash the recovery image into device)
---------------------------------------------------------------
操作如下:
K:\m370>fastboot -i 0x0489 boot twrp-recovery-v3.0.2.0_infocus-m372.img
downloading 'boot.img'...
OKAY [ 0.484s]
booting...
OKAY [ 0.078s]
finished. total time: 0.562s ===> 這裡進入twrp 沒問題
----------------------------------
K:\m370>adb devices
List of devices attached
FOTGLMB5A2404968 recovery ===> 裝置沒問題

---------------------------------------------------------------
K:\m370>adb push twrp-recovery-v3.0.2.0_infocus-m372.img of=/tmp/rec.img
failed to copy 'twrp-recovery-v3.0.2.0_infocus-m372.img' to 'of=/tmp/rec.img': N
o such file or directory

No such file or directory ======>檔名沒錯啊??

不太懂得是
如果可以進入TWRP了 為什麼還要用指令?
都可以在TWRP中刷ROM 刷SU 刷RECOVERY

PS.無此檔名應該指=>of=/tmp/rec.img

把twrp 刷進手機比較方便啊，不用再透過電腦

of=/tmp/rec.img ===> 這是什麼奇怪語法??

dd if=/tmp/rec.img of=/dev/block/mmcblk0p29

這個語法很明顯是在Linux Shell下執行的

由Busybox tools提供的command

絕對不是在Bootloader runtime執行

dd if / of後面都是路徑

應該是在正常開機下USB連接PC Console

進入debug mode

從PC下指令給手機Android來操作
