[TWRP] Screenshot while in recovery..

Is this what I have to do to take a screenshot in the recovery? Using adb:
adb pull /dev/graphics/fb0
ffmpeg -vframes 1 -vcodec rawvideo -f rawvideo -pix_fmt rgba -s 720x1280 -i fb0 -f image2 -vcodec mjpeg fb%d.jpg
EDIT: I tried using ddms.bat while in recovery but it doesn't recognize my phone. I don't know what else to do or why it's not recognizing it. Can someone try with their phone and see if it works?
EDIT 2: ddms.bat works fine to take a screenshot when the device is booted up. Just not in the recovery.

yes that is correct, however its device specific on the fbX most all are 0, some can be a different number, just try until you find the correct one,
also note that the colors my be off, and if they are simple change the
rgba around,
for instance my red was blue and blue was red,
just changed the order from
rgba to bgra and problem solved

That's great, however -vframes belongs to the output.
adb pull /dev/graphics/fb0
ffmpeg -vcodec rawvideo -f rawvideo -pix_fmt rgba -s 720x1280 -i fb0 -f image2 -vcodec mjpeg -vframes 1 fb%d.jpg
If the device is in landscape mode you have to invert the resolution:
adb pull /dev/graphics/fb0
ffmpeg -vcodec rawvideo -f rawvideo -pix_fmt rgba -s 1280x720 -i fb0 -f image2 -vcodec mjpeg -vframes 1 fb%d.jpg

Hi Friends!
Is it possible with the same method to take screenshot on normal (not TWRP) LineageOS mode?
Code:
adb pull /dev/graphics/fb0
failed to copy '/dev/graphics/fb0' to './fb0': open failed: Permission denied
What is the correct video device for standard LineageOS mode?
Many thanks!

FFMPEG

Is anyone familiar with ffmpeg? Im trying to get a screenshot of my htc one x in recovery and ddms wont work. So I tried to pull the dev/graphic/fb0 file and I have successfully pulled it but i'm unable to get ffmpeg to convert it to a picture format like png or jpeg. I'm running these commands
adb pull /dev/graphics/fb0
ffmpeg -vframes 1 -vcodec rawvideo -f rawvideo -pix_fmt rgba -s 720x1280 -i fb0 -f image2 -vcodec mjpeg fb%d.jpg
When I run it it says option vframes (set the number of video frames to record) cannot be applied to i
nput file fb0 -- you are trying to apply an input option to an output file or vi
ce versa. Move this option before the file it belongs to.
Error parsing options for input file fb0.
Error opening input files: Error number -22 occurred.
What am I doing wrong?

change splash.img for qualcom use android

hi everyone :fingers-crossed:
This is TUTORIAL
and its my first post on xda,
original post with PC @GokulNC https://forum.xda-developers.com/member.php?u=6319272
with android by rivv (especially for xiaomi)
req :
1.android cmd shell (term emu or etc, :good: play store)
2.file https://m.facebook.com/groups/45000...t_reply&notif_id=1503036517686899&ref=m_notif (download all given link there, include busybox for support cmd and the splash maker)
cause the file in Indonesian languange so I'll translate it
instructions :
1.flash the busybox file using recovery like twrp etc
2.open the flash file and extract lib folder, then copy onto lib folder on your system and copy splash folder to data.
Note : in splash folDer just need copy the header file (this still for xiaomi 2/3) for universal u need edit splash file on lib folder and custom header.img.
Like me cause I'm using ZTE a711 so I must edit splash file like that :
if [ -f splash.png ]; then, into if [ -f /data/pics/logo.PNG ]
if [ -f header.img ]; then, into if [ -f 1080x1920_header.img ]
like I'm say different dir and header IMG u need unpack bfore
then delete this line (optional) :
ffmpeg -i splash2.png -f rawvideo -vcodec rawvideo -pix_fmt bgr24 splash2.raw > /dev/null 2>&1
change header with 1080x1920_header.img and del sec header and splash2.raw (opt) :
cat header.img splash.raw header.img splash2.raw > splash.img
3.open cmd and type :
su
splash
the options : 1. for make custom splash
2. install custom splash
3. backup installed splash
4. restore backupped splash
5 exit cmd
Done

How to edit boot.img for SM-T585?

I want to edit the boot.img for SM-T585, but I can't edit initrd.img. I'm using abootimg and I tested that it works by unpacking and repacking the boot.img without doing any thing to the initrd.img:
Code:
abootimg -x boot.img
abootimg --create newboot.img -k zImage -r initrd.img -f bootimg.cng
and this image can be flashed and the device boot normally, but when I try to modify the initrd.img:
Code:
mkdir initrd_folder && cd initrd_folder
# extract the [B]initrd.img[/B]
zcat ../initrd.img | cpio -idmv
# pack it again
find . | cpio --create --format='newc' | gzip -9 > ../newinitrd.img
From: How To Modify initrd.img
and then create the new boot.img with the new initrd.img
Code:
abootimg --create newboot.img -k zImage -r newinitrd.img -f bootimg.cfg
This new boot.img doesn't make the device boot and it only shows the Samsung logo and then reboots

How To Guide Guide to flash images in Linux

as we known, there's a famous tool called Tiny Script Tool to flash our custom systems. but i hate windows, is there a way to flash images in linux? at lease in linux there's no driver needs to all adb devices, thats perfect!
this guid will led you to do it in linux.
as Moto edge s is a dynamic partition device, these options suite to all devices with super block.
maybe YOU HAVE TO USE ROOT OR SUDO TO ACCESS YOUR DEVICE. change to root user if you can't access your device in linux.
# automatic tool:
i've wrote it as a script tool, see https://github.com/superiums/TrinyFlashScript
# manually steps:
## 刷机步骤
1. 备份app
Bash:
#!/bin/bash
backdirs='/dev/shm/app_backup/'
if [ ! -d "$backdirs" ]; then
mkdir $backdirs
fi
# user 0
backdir='/dev/shm/app_backup/0/'
if [ ! -d "$backdir" ]; then
mkdir $backdir
fi
adb shell pm list packages --user 0 -3 -f |awk '{ORS="\n";sub(/package:/,"adb pull ");sub(/apk=/,"apk '$backdir'");print($0".apk;");print("")}' >$backdir'dolist.sh'
sh $backdir'dolist.sh'
# ----------back app for user 10, if you have insular installed in your phone, this is needed!!! ********otherwise, skip.*******
backdir='/dev/shm/app_backup/10/'
if [ ! -d "$backdir" ]; then
mkdir $backdir
fi
adb shell pm list packages --user 10 -3 -f |awk '{ORS="\n";sub(/package:/,"adb pull ");sub(/apk=/,"apk '$backdir'");print($0".apk;");print("")}' >$backdir'dolist.sh'
sh $backdir'dolist.sh'
# ---------------------------------------------------------------------------------------------------------------------
2. 备份数据
Bash:
adb pull /sdcard/Downlad .
3. 重启到fastboot模式,刷写非动态分区
> **非动态分区包括**:
>
> - vbmeta
> - vbmeta_system
> - boot
> - vendor_boot
> - dtbo
Bash:
adb reboot bootloader
# 或 volumne- & power 开机
# 验证是否fastbootd模式
fastboot getvar is-userspace
# 应返回 no
fastboot flash [partition][_slot] [image]
# clear userdata and meta
fastboot -w
4. 重启到fastbootd模式,刷新动态分区
> **super分区包括**:
>
> - system
> - system_ext
> - vendor
> - product
Bash:
fastboot reboot fastboot
# 验证是否fastbootd模式
fastboot getvar is-userspace
# 应返回 yes
fastboot flash [partition][_slot] [image]
6. 双清
Bash:
fastboot erase userdata
#或
fastboot -w
#完成,重启到新系统
fastboot reboot
7. 设置系统
Bash:
#-------------for chinese users only, because they are blocked by the GFW and not able to connect to google.--------------
#Android 7及之后的版本输入如下两个命令,设置网络检测地址:
adb shell settings put global captive_portal_http_url http://www.google.cn/generate_204
adb shell settings put global captive_portal_https_url https://www.google.cn/generate_204
#可以输入如下命令, 禁止检测网络连接状态.
adb shell settings put global captive_portal_detection_enabled 0
#---------------------------------
#---------- if you are concern to your private data, this is usefull.
#强制开启分区存储
adb shell sm set-isolated-storage on
9. 恢复软件及数据
Bash:
cd 0
ls -1 *.apk | xargs -ti -n 1 adb install --user 0 {}
#------------- after install insular--------------------
cd 10
ls -1 *.apk | xargs -ti -n 1 adb install --user 10 {}
adb push ./Downloads/* /sdcard/Downloads/
hopes this help.

the insular mentioned above is this package: com.oasisfeng.island.fdroid.apk
which will create sperate user space for your storage , called "work profile".
if you bricked your device, try these options:
(Every flash lover should backup a stock image for future!)
RSA solution, flash back to stock firmware. follow Skip to content for windows, follow these commands for Linux:
Bash:
command
