Not rebooting into recovery mode? - Nexus One General

On step three of the AndroidandMe.com tutorial once I have to enter "adb reboot recovery" in command prompt it reboots the phone but does not goto the menu and whatnot. It just has a /!\ with a android under it. What does that mean and how do I fix it?

Reflash the recovery image.

GUIDE
now unlock bootloader.
and go for step 4(which flash twrp recovery)
now flash the recovery which is provided by me using code.
and now go can go into recovery
****************************************************************************************************
i suggest you this guide this method do for me
Disable update CM recovery option in developer options... Then flash custom recovery.... it will work.
once flashing twrp recovery, you will need to use
Code:
fastboot -i 0x1ebf reboot
command.
remove battery after install recovery before restarting phone
then insert battery and start in custom recovery
install Custom Recovery
1) enable developer options
2)enable advance reboot and usb debugging
3)disable Update CM recovery option
4)reboot to bootloader and flash recovery
" fastboot -i 0x1ebf flash recovery recovery_twrpyulolli.img "
5) directly disconnect phone (phone displaying FASTBOOT MODE)
6) remove battery and start phone in recovery mode using volume UP+DOWN and power key
7) And YOUR are IN TWRP RECOVERY ......
THIS method work for me perfectly .....i m also having same problem of flashing custom recovery and again showing CM RECOVERY
:laugh::laugh:
Thank You...!
Which is best for yureka cwm or twrp recovery
I'm facing the same problem but this trick didn't work for me.

Wiped recovery partition and bricked my galaxy s4

I wiped recovery partition by issuing following command in adb console.
Code:
dd if=/data/cm-11-20160320-NIGHTLY-jflte-recovery.img of=/dev/block/mmcblk0p10
reboot recovery
now my phone stucked up in the boot-up screen. I guess the image i flashed into recovery partition was invalid and because i issued 'reboot recovery' command it tries to boot from recovery image which is invalid. Is there a way to delete bcb (bootloader control block) in order to delete that 'reboot recovery' command ?

Is your phone rooted? If it is, then install quick reboot from playstore, grant it root permissions and you can enter TWRP.. but if it is not rooted, probably you can't.

Connect your phone to pc, enable usb debugging, if you donot have minimal adb and fastboot in your pc, download them, then open command window in that folder by shift+right click and then selecting 'open command window here'..
New cmd window should open and now type 'adb devices'
Then if your phone asks for authentication, grant it.
Now you should see your device number in the list of devices attached.
Enter 'adb reboot recovery'. Done.
Type the commands without punctutations.

It means, you lost twrp recovery. Stock recovery replaces it if you donot delete recoveryfromboot.p file from --root/system/
If your phone is rooted try to delete that file from any third-party file managers which can have root folder access.( Es file explorer or root explorer). Now install TWRP again with adb commands. I hope you could now enter TWRP without any issues. Good luck:good:
Or
After connecting phone to pc, in the command window opened in minimal adb and fastboot folder, type 'adb reboot fastboot' Now the phone enters directly into fastboot.
Flash recovery with the command
'fastboot flash recovery name.img'
(replace 'name' with the name of the recovery image') and boot into recovery as soon as you flash(must).
Now in TWRP goto advanced, file manager, goto system folder and you could see recoveryfromboot.p file. Select it, delete it. And now you can enter TWRP without any issues
try this for TWRP recovery..
1. Enable USB debugging and OEM unlocking from developer options and connect your AD (Android Device) to PC ,say yes to your phn settings
2.you need custom recovery image(******.img) of TWRP and it should be copied to the adb tools folder
3.open "unlock recovey " from adb tools and as AD goes to fastboot mode ,allow your phone to do so
4.press (shift+right click) on adb tools select "open command window here"
5.type in "adb devices" make sure it says all listed devices are connected and type in "fastboot flash recovery ******.img"
6.everything will be done afterthat unplug your devices and google your recovery key combination then you will directed to twrp recovery
i had the same problem.. repair your volume down button and do the rest before that key stops working again.

I'm not sure how you installed a Custom Recovery on your phone without Rooting it first. Rooting isn't required for the same, but it does interfere with the flashing process most of the times.
Anyhow, if your device is entering the Stock Recovery instead of the Custom Recovery, then you have simply not flashed the Custom Recovery onto your phone in the first place. A Custom recovery, when flashed, should overwrite the Stock Recovery on your device. This means that you won't have both the Custom Recovery and the Stock Recovery on your phone at the same time.
You'll have to flash the Recovery again and this time, try flashing the Recovery with a Rooted phone. You'll be able to enter your custom Recovery then.

[Need help]Rooting moto g4 plus in stock june security patch level.

I want to root my moto g4 plus(unlocked bootloader and twrp flashed). Anyone knows how to root moto g4 plus. And i also want to know that how to increase battery backup after rooting(is it a myth).
@ADITYA_KUMAR this has been asked and explained many times and once more.
- Take Backup
- get Elemental-X kernel (see development section and download correct one )
- flash with TWRP
- get latest SuperSU : SuperSU
- now you can follow same guide of MM from step 5 : Guide

What happens if you select Recovery from Bootloader ? Is it booting in Stock Recovery ?
In TWRP go to Backup and make backup of /system /data /boot.
If anything bad happens while flashing/Rooting then you can restore it.
The first time, you must open TWRP from the bootloader directly or the recovery gets overwritten.
For rooting, you can flash Magisk instead of flashing SuperSu. Other steps remain exactly the same.

Commands used:
Fastboot flash recovery name.img
It gives output as image not signed or corrupt.
After that i typed command fastboot reboot bootloader.
I open recovery mode. It opens twrp. But after i restart my phone. It automatically removes the twrp.

This is your problem. You must open recovery from the bootloader menu the very first time. Or TWRP is overwritten with stock recovery. I don't know why that is. But that is how it is...

Reboot into bootloader.
Flash recovery - fastboot flash recovery twrp-xxx.img
Open recovery from bootloader menu (by using the volume and power buttons)
From there you can reboot and your recovery will work normally after this, most probably.

It didn't work. I flashed twrp. I opened recovery mode by using volume down to scroll to recovery mode and power button to select it. I booted in twrp mode and rebooted system from there. After that i power off my phone and tried to open twrp again, but it is showing no commands only. I didn't boot into twrp again.

Try commands,
fastboot oem fb_mode_set
fastboot flash recovery name.img
Fastboot oem fb_mode_clear
Then directly boot into recovery,
Then again boot into recovery through twrp itself (there is option for it in reboot) or try anything.
Thank you guys i successfully rooted my moto g4 plus(xt1643)

flashing oneplus one

howto flash the one without working volume controls??
is this possible?
Yes, it is possible. LineageOS has an option to boot to recovery or fastboot via the standard reboot dialogue.
You can also use adb commands "adb reboot recovery" or "adb reboot fastboot".

thanks for the reply. is there any manual to do so?
for im´m an absolute newbie on this. adb and faastboot are installed on my ubuntu machine.
Depends on what you are trying to accomplish.
Flash TWRP recovery? You may also use LineageOS recovery instead of TWRP if you want. Follow their instructions https://twrp.me/oneplus/oneplusone.html
Flash LineageOS? Follow the wiki instructions https://wiki.lineageos.org/devices/bacon/install
Beware that unlocking the bootloader will erase all data on the phone.

While in fastboot mode, you may boot into recovery using "fastboot reboot recovery". Almost there, good luck!

doesn't work on my ubuntu machine. "unkown rebbot target recvery..
i tried .guess i check it on my win machine.
You can also reboot to recovery from within the OS by using "adb reboot recovery". It should work if you were able to reboot to fastboot using this method.
unfortunately it does not work while being in fastboot mode.
adb says device 'null'not found..
Yes, you are supposed to use adb from whatever OS you have installed, CM, CyanogenOS, LOS, ...
but?
is flashing possible without being in fastboot mode? just using adb?
I understood that you had already flashed the recovery. Now you need to boot into the recovery to flash an OS.
Fastboot is used to flash the recovery.
Recovery is used to flash the OS.
yes i think that's it and therefore i had to reboot to recovery without working controls..

You have a working operating system installed? Cyanogenmod, LineageOS or something similar?
Use the power button to boot into the operating system. Then connect the phone to your PC and "adb reboot recovery".
