[P8lite General] catalinutzz:
when i type the string : fastboot flash recovery.img it says cannot determine image filename for 'recovery.img' i don't understand what's wrong..

i figured it out it was adb fastboot,not just fastboot.

it worked and that's the log... :

C:\adb>adb fastboot flash recovery.img

Android Debug Bridge version 1.0.32

Revision eac51f2bb6a8-android

-a - directs adb to listen on all interfaces for a c

onnection

-d - directs command to the only connected USB devic

e

returns an error if more than one USB device is

present.

-e - directs command to the only running emulator.

returns an error if more than one emulator is r

unning.

-s <specific device> - directs command to the device or emulator with

the given

serial number or qualifier. Overrides ANDROID_S

ERIAL

environment variable.

-p <product name or path> - simple product name like 'sooner', or

a relative/absolute path to a product

out directory like 'out/target/product/sooner'.

If -p is not specified, the ANDROID_PRODUCT_OUT

environment variable is used, which must

be an absolute path.

-H - Name of adb server host (default: localhost)

-P - Port of adb server (default: 5037)

devices [-l] - list all connected devices

('-l' will also list device qualifiers)

connect <host>[:<port>] - connect to a device via TCP/IP

Port 5555 is used by default if no port number

is specified.

disconnect [<host>[:<port>]] - disconnect from a TCP/IP device.

Port 5555 is used by default if no port number

is specified.

Using this command with no additional arguments

will disconnect from all connected TCP/IP devic

es.

device commands:

adb push [-p] <local> <remote>

- copy file/dir to device

('-p' to display the transfer progress)

adb pull [-p] [-a] <remote> [<local>]

- copy file/dir from device

('-p' to display the transfer progress)

('-a' means copy timestamp and mode)

adb sync [ <directory> ] - copy host->device only if changed

(-l means list but don't copy)

(see 'adb help all')

the format is a list of lines with the followin

g format:

adb forward <local> <remote> - forward socket connections

forward specs are one of:

tcp:<port>

localabstract:<unix domain socket name>

localreserved:<unix domain socket name>

localfilesystem:<unix domain socket name>

s

if <local> is already forwarded

adb forward --remove <local> - remove a specific forward socket connection

adb forward --remove-all - remove all forward socket connections

adb reverse --list - list all reverse socket connections from device

adb reverse <remote> <local> - reverse socket connections

reverse specs are one of:

tcp:<port>

localabstract:<unix domain socket name>

localreserved:<unix domain socket name>

localfilesystem:<unix domain socket name>

adb reverse --norebind <remote> <local>

- same as 'adb reverse <remote> <local>' but fail

s

if <remote> is already reversed.

adb reverse --remove <remote>

- remove a specific reversed socket connection

adb reverse --remove-all - remove all reversed socket connections from dev

ice

adb jdwp - list PIDs of processes hosting a JDWP transport

adb install [-lrtsdg] <file>

- push this package file to the device and instal

l it

(-l: forward lock application)

(-r: replace existing application)

(-t: allow test packages)

(-s: install application on sdcard)

(-d: allow version code downgrade)

(-g: grant all runtime permissions)

adb install-multiple [-lrtsdpg] <file...>

- push this package file to the device and instal

l it

(-l: forward lock application)

(-r: replace existing application)

(-t: allow test packages)

(-s: install application on sdcard)

(-d: allow version code downgrade)

(-p: partial application install)

(-g: grant all runtime permissions)

adb uninstall [-k] <package> - remove this app package from the device

('-k' means keep the data and cache directories

)

adb bugreport - return all information from the device

that should be included in a bug report.

adb backup [-f <file>] [-apk|-noapk] [-obb|-noobb] [-shared|-noshared] [-all]

[-system|-nosystem] [<packages...>]

- write an archive of the device's data to <file>

.

If no -f option is supplied then the data is wr

itten

to "backup.ab" in the current directory.

(-apk|-noapk enable/disable backup of the .apks

themselves

in the archive; the default is noapk.)

(-obb|-noobb enable/disable backup of any insta

lled apk expansion

(aka .obb) files associated with each applic

ation; the default

is noobb.)

(-shared|-noshared enable/disable backup of the

device's

shared storage / SD card contents; the defau

lt is noshared.)

(-all means to back up all installed applicatio

ns)

(-system|-nosystem toggles whether -all automat

ically includes

system applications; the default is to inclu

de system apps)

(<packages...> is the list of applications to b

e backed up. If

the -all or -shared flags are passed, then t

he package

list is optional. Applications explicitly g

iven on the

command line will be included even if -nosys

tem would

ordinarily cause them to be omitted.)

adb sync notes: adb sync [ <directory> ]

<localdir> can be interpreted in several ways:

- If <directory> is not specified, /system, /vendor (if present), /oem (if pre
