adb reboot recovery not opening recovery - LG Optimus 4X HD

I can not go to recovery (stock or custom) with "adb reboot recovery" command (adb is otherwise working). It just reboots the phone.
Third party apps to reboot in recovery not working also, except ROM Manager. I recently installed AOSP (by MoltenMotherBoard) it is not rooted. Now I can not reboot in recovery with ROM Manager.
My phone buttons are dead, only software solution is needed.
How to fix this?
Need in immediate help.

IMHO, this xda post is closest theory on "setup-recovery" p880 trick : https://forum.xda-developers.com/showpost.php?p=22212494&postcount=22
Also , only twrp is handling specific stuff : https://github.com/omnirom/android_bootable_recovery/search?utf8=✓&q=rebootrecovery.sh&type=Code
Thx to twrp300/multirom sources , looks latest Multirom Trampolinev27 (slightly modified) with both reboot options
- regular reboot to bootloader/fastboot OK
- modified/warm reboot to recovery with f2fs OK: press/power only straight to recovery, or no-press straight to primary AND 1st reboot from aosp6/7 straight to recovery; both with f2fs !
Finally there are many ways to run "setup-recovery",without PCadb & within aosp6/7, 3Ctoolsboxfree(+su) or even Kadiutor via init.d section: copy system/bin/setup-recovery to etc/init.d/ then use KAdiutor/init.d section to trigger the script + 3dots reboot...
Attached is a very old 2013 asian transcription for in-tech view (UNCONFIRMED! caution); if some have info on mmcblk0p14, let us know.

[Q] nandroid via adb or fastboot

hi to all!! i have a doubt....
can i do a nandroid backup of my current rom using adb or fastboot parameters??
anyone can write or leave it here?
thank´s in advance!!
No. Custom recover does it. You can issue the adb reboot recover command to get into it etc....
Sent from my Nexus One using XDA App
Yea...maybe its the reason that i dont know this parameter lol
sent from my amstrad CPC powered by LOL..(premium xda)
You sure can do it from adb. I had to find this out when I cracked my AMOLED screen and had to try and back everything up without being able to use the screen of my phone.
You need to be in recovery for it (you might be able to backup with fastboot as well, but I didn't have my bootloader unlocked at the time), so if you are full booted up, reboot into recovery and follow these commands.
Code:
adb reboot recovery
adb shell
nandroid backup
Nice and simple, right?

At what point is this failing? I assume you actually have an sdcard loaded in the phone?

shell shows me this when i put my device into recovery and enter the code that was provided to my above...sd card is in my device... but i think that the problem is that i don´t know what´s exactly the status that the phone need to stay.. into recovery with sd card usb mounted?(i think that not)
with the phone booted and in usb debugging mode & only chargue?
If you are booted into the phone (ie. fully loaded and able to use your phone), you need to issue the adb reboot recovery command. If the phone is off, hold down the volume down button as you are booting up. This will load the bootloader. From there, it will do a little check, and then you can use the volume keys to go to Recovery. Hit the Power button to select it. The phone will load the 'X' screen and eventually be in recovery (the text should be green or orange).
Once you are in recovery, you don't need to do anything else on the phone. Just issue
Code:
adb shell
nandroid backup
(You might have to issue the 'su' command if it shows a $ instead of a # before you run the backup.)

Should I just flash the CW2xxx over the CW3xxx and then proceed with the nandroid backup? I can't use my screen at all, so will that be a problem?

[REQ]Dump of initial rom on N5 (Instructions inside)

Progress:
KFS78N: not needed
KQS81M: not needed
Click to expand...
Click to collapse
Introduction:
I would like to request users to dump KFS78N and KQS81M.
(The roms that were initially installed on the N5 at release)
As there is already an ota to KRT16M, the only way to get it is from a device that has never past the welcome screen when you turn the device on for the first time
Click to expand...
Click to collapse
Eligibility:
You have a desired rom if the following are true
You have not installed the ota that is required during setup
Your bootloader is either HHZ10x or HHZ11a (specifically any that isnt HHZ11d) in fastboot
Instructions to enter fastboot are below
Click to expand...
Click to collapse
Requirements:
Adb and fastboot set up
basic understanding of the command line/shell
A custom recovery (such as TWRP)
There are many guides on how to set up fastboot for a device and tutorials on using the command line on the internet.
You will need the newest android sdk to set up adb/fastboot easily for this device.
Beyond that there are no additional/unique steps to it.
Click to expand...
Click to collapse
Instructions:
Unpack N5 from box
Charge it to ~60% (recommended, may not be required)
Enter fastboot mode:
Make sure device is off
Hold down volume up + volume down + power until you reach the fastboot screen
If you accidently turned it on normally: just turn it off and try again, it is not an issue as long as you dont finish the initial welcome/setup
open up fastboot and enter: "fastboot oem unlock"
follow onscreen instructions to unlock
enter "fastboot boot <path to custom recovery>"
Follow onscreen instructions and make a nandroid
Let it finish and go back to the recovery top most menu
Make sure /sdcard is mounted
Go to mounts (or it's equivilent)
Check that /sdcard is a mounted partition
enter "adb shell"
Dump the radio
"dd if=/dev/block/platform/msm_sdcc.1/by-name/modem of=/sdcard/radio.img
Dump the bootloader
"dd if=/dev/block/platform/msm_sdcc.1/by-name/aboot of=/sdcard/bootloader.aboot.img
"dd if=/dev/block/platform/msm_sdcc.1/by-name/imgdata of=/sdcard/bootloader.imgdata.img

[Q] Recovery writing problems

I've installed CM12 on my Xperia Z and with this Rom CM Recovery was also installed, to finish the installation I tried to flash gapps, but CM recovery said: "Cannot load volume/misc" so I tried to install another Recovery and got the error: " sending 'recovery' (4876 KB)...
OKAY [ 1.131s]
writing 'recovery'...
FAILED (remote: not allowed)
finished. total time: 1.458s
Rom manager says that CWM is already installed, but there's only CM recovery. I can use another recovery when I flash CWM as boot. So how can I get CWM or TWRP back?
Thanks in advance

which CM12 have you installed, you may want to install TWRP Recovery. If you prefer
http://teamw.in/project/twrp2/187
download openrecovery-twrp-2.8.5.0-yuga.img from the above link.
then do this
adb push openrecovery-twrp-2.8.5.0-yuga.img /sdcard/
adb shell
su
dd if=/sdcard/openrecovery-twrp-2.8.5.0-yuga.img of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel

exit again
adb reboot recovery

I've followed this, and it's solved all my recovery problems, I've got just one question. (I'm on Latest CM12 Validus build), when flashing newer builds, will I need to do this again or will recovery remain?

as long as you are on any of the CM12 builds even custom builds based on CM you do not need to reflash, unless you want to update TWRP itself.

Hi there.If you have root access and unlocked bootloader,you can install TWRP even without pc connection.
first you should download a terminal emulator app from google play.
then you should download the latest version of TWRP image file from here https://dl.twrp.me/yuga/.
Place it in the root of your /sdcard folder and rename it to twrp.img
Run the following commands in terminal app
Code:
su
and then we write recovery image file to FOTA with dd command.
Code:
dd if=/sdcard/twrp.img of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel
and it's done.
press thanks if it was helpful.
i installed hk lollipop zip from my custom twrp recovery. and when rom istall has finished ; recovery gone.

Below are 2 solutions to get a properly working recovery
Preperation:
1. Download Dual recovery installer: XZ-lockeddualrecovery2.8.23-RELEASE.combined.zip
2. Install NDRUtils
Next up we will test if the TWRP you installed works or not
-open NDRUtils and choose to boot into TWRP recovery.
Now unhide the result that you got to continue with the installation:
OK: I am now in TWRP
flash XZ-lockeddualrecovery2.8.23-RELEASE.combined.zip and reboot.
Everything will work normally now.
Not OK: I am not in TWRP
Reboot the phone if you have to (hold power until you feel 3 vibrations and then turn the phone back on)
You need to download this: http://nut.xperia-files.com/path/XZDualRecovery/Kernel_Builder
To get the right file make sure to selec the xperia z c6603 and select the rom version you are using, you can view what you have in settings, about phone, build number.
it will be much easier for you if you install this: X-plore File Manager The reason i recommend this application is that it automatically makes sure the file rights are correct.
Go into the settings and enable superuser +mount root mode
Now you can browse to the folder where you downloaded the zip in the left pane.
go into the zip and and then into tmp
Select the boot.img
now move to the right pane and browse to the root of your SD card like the comment above
go back to the left pane and with boot.img still checked click copy.
Now follow the original instructions mrp1375 gave you, but notice the different filename
Open terminal
Type : su
Type: dd if=/sdcard/boot.img of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel
Now you can reboot and if it worked the phone will vibrate twice and show a green led meaning you can press the down button to enter TWRP recovery.
Go into the recovery and now flash XZ-lockeddualrecovery2.8.23-RELEASE.combined.zip so you get a proper installation
Now remember this very important fact:
Whenever you flash or wipe anything you MUST reinstall recovery and root again.
This is a failsafe strategy you can NEVER ignore becaus of your usb issues.
Keep SuperSu installer and XZ-lockeddualrecovery installer on your device at all times!
thank you

Well, just tried it.. When i used the adb reboot bootloader command, the phone turned off and the screen where it says "Phone is locked" poped out. I freaked out, plugged the phone out, and restarted it . Is that supposed to happen?
Everything worked up until the step :
- Now you must delete the SetImmutable.list from System on P7!

I'm still not able to delete this file as it's protected. I would assume SU would ask me to confirm the rights to allow the filemanager to do it but it doesn't.
Any ideas?
Other than that, great instructions on installing the recovery and SU! :good:
EDIT:
Found the right post:
Here are instructions for installing VIPER4Android on P7
1) have your phone ROOTED
2) install BUSYBOX from PLAYSTORE
3) install terminal emulator from PLAYSTORE
4)open Terminal Emulator and type in the following commands exactly:
su
mount -o rw,remount /system
cd system
lsattr
chattr -R -i *
rm –f /system/set_immutable.list
lsattr
After this set_immutable.list should be removed and you should have full access. Now you can install VIPER4Android
Work on my P7-L10
