Help! twrp not loading!

I just used this method
""Enter the following commands to flash TWRP Recovery on your tablet:
adb reboot bootloader
fastboot flash recovery openrecovery-twrp-2.2.1-grouper.img
TWRP Recovery will then be flashed on your Nexus 7.
You will also get a “Finish/Okay” message at the command prompt. Type this command to reboot your tablet:
fastboot reboot
To enter TWRP Recovery, switch off your tablet. Press and hold the Volume Up, Volume Down, and Power buttons together.""
to install twrp on my nexus 7(rooted and unlocked with stock ROM).
It went well but when i try to boot it into recovery mode from bootloader, its just stuck a the google symbol screen.
I tried an alternative, using goo manager. when i reboot it using goomanager, it goes into twrp but not when i manually reboot the device and go into bootloader mode... Please help!!!!!

There's a bug in the boot loader that requires you to be plugged into a computer to access recovery.

as previously mentioned, there is a bug.
I can boot into TWRP via hold Power button -> Reboot -> Recovery, if your ROM [stock rom?] does not have this, download ROM Toolbox on Play Store, and select "Rebooter" on the bottom, and "Reboot recovery"
Or I think you can use Terminal Emulator, and type
# su
# reboot recovery
that should work too..
or you can just plug it into a computer

Thanks a butt load!!!!!!!!!!

I also think goomanager or rom manager has a bug that it wont let me power on my tablet unless i hold the power button down for 10 seconds. I remove those apps then all is fine.

Trouble flashing 5.0.0! Help needed!!!

Need help here!
My Nexus 10 was with stock 4.4.4, rooted with TWRP. I decided to flash the factory image files by removing the -w in flash-all.sh. However it ended up with being stuck with the rotating balls. After about 45 minutes, I decided to go to the fastboot mode (pwr+both volumes), then select recovery (I planned to do factory reset and clear cache). After trying to reboot into recovery mode (pwr + one volume button), it now shows an open bootloader with following message below the bootloader (the bootloader seems still unlocked):
Dowloading...
Do not turn off target!!
What does it mean? What is it exactly downloading? And what should I do? Should I lock the bootloader? Also it does not respond now if I push the volume buttons. It's not recognized on my Mac with the with the following command:
fastboot devices
I also notice the following line:
Reboot Mode Flag: NONE
Now I just booted into recovery, but it shows the bootloader with the exclamation mark! After a few minutes, it automatically switched to the never-ending rotating balls. What can I do?

When you get the Downloading...message you're in the Recovery screen. Don't worry about the message. Press vol up and power to get into the recovery menu - there you can wipe cache and system. As you're in recovery, Fastboot devices will not recognise your tablet, only adb commands.
If I was you and this didn't work, I'd just reboot into fastboot and flash the image files manually. You'll lose root, data and twrp but these can easily be gotten back through fastboot.

Fastboot Screen & no reboot into Recovery from System

Hy,
after install some CM13 builds i see that the Fastboot Screen thats normaly only Black screen with Fastboot OEM now changed into CM Menue.
First question how i can bring back into original Fastboot Black screen.?
The second problem is that i cant boot into recovery or bootloader from Android System. I press/hold Power then i can choose recovery or bootloader, after restart automatically system restarts....
As Recovery i flashed TWRP.
When i start the Phone by pressing Vol + and Power i can go into recovery, ( this way works )
at the moment i use the original Stock ROM because the CM Builds seems not working fine with my Bluetooth in Skoda/ VW Radio.

When in fastboot do
" fastboot boot twrp-xxxx-kipper-xxxx.img "
it should boot to twrp. instead of writing filename, write fastboot boot (SPACE) and drag the TWRP file to command window. After pressing ENTER you will get twrp. Do a factory reset and flash COS 12.1.1 zip file. If you need i can give you link to it

When my phone is in fastboot I don't see it on cmd "adb devices".

I tried with different drivers etc. but its just don't work, i downloaded TOOL ALL IN ONE, but this said that device was found but not said what or which device, only when phone is normally started i see it on the list of "adb devices" and in TOOL ALL IN ONE. Please help thanks in advance =)

Fastboot is an entirely different mode from adb, and as such it requires a different tool. In the console there is a command "fastboot", which is what you need to use to interact with the phone in fastboot mode. You can boot into fastboot mode from power off with the USB to computer plugged in by holding Volume Down, or it might be possible with TOOL ALL IN ONE, I haven't used it much.
Some basic commands:
fastboot flash unlock path/to/unlock.bin # This will flash the unlock bin
fastboot getvar unlocked # This will check if the device is unlocked
fastboot reboot # This will reboot the phone into normal mode, since powering off by holding the power button is a pain
To flash TWRP, there's a more advanced process with some specific requirements, but I'd be happy to share those if wanted.

Yeah, so I wanted to flash TWRP but it doesen't seem to work i did what was said in many guides but maybe if you tell me how to do it, it will work =) Thanks
So i tried to flash TWRP with the TOOL ALL IN ONE, everything was okey but then error happened called "Unknown device"

First of all, which version of G6 do you have? The US997 one, or the H870?

H870

For H870 I'm not entirely sure, but I know that for the US997 you have to do a special procedure to make it permanent. Make sure you back up everything first, too.
With the phone in fastboot mode and a computer connected with fastboot installed and the twrp zip downloaded as "twrp.zip" (or whatever you want):
Make sure the bootloader is unlocked: fastboot getvar unlocked (should return "yes" or "true").
Flash the recovery: fastboot flash recovery twrp.zip (replace twrp.zip with the relative or absolute filepath/name).
Unplug the phone from the computer and reboot into recovery by holding Power and Volume Down. When the logo appears, lift your finger off the power button briefly and then continue pressing.
When you get to the factory reset menu hit yes twice, then the phone should boot into twrp (it may flash the LG logo, I've had different behavior on different phones. You won't need to hold the Power-Volume Down combo any more).
In twrp, swipe to allow modification, then in the Wipe menu select Format Data (and enter yes). This will wipe the phone, so make sure everything was backed up beforehand.
From the main menu go to the Reboot menu and select Recovery.
Here it might vary from the US997. Below are suggestions which I think are needed to have it work.
Download the no-verity-opt-encrypt zip, and connect the phone to the computer.
Once it's rebooted into recovery mode: adb push path/to/no-verity.zip /sdcard/
Then from the install menu in twrp install the zip.
Reboot into System from the reboot menu on the homescreen of twrp.
That should do it all.

my huawei p8 lite reboot in logo continuously and black screen

I've tried everything I've found in this forum and other forums, but nothing has worked
I flashed many systems with fastboot, the factory firmware, upgraded versions and many more.
erased all data, all combinations of buttons, update by recovery, nothing worked, I do not know what to do.
I have seen dozens of logo loop tutorials, none of them have worked for me.
Any idea, or my phone is dead? thx. (my mobile is huawei p8 lite ale-L21 CE0197)

If you can boot into fastboot then we can "revive" your phone.
Follow these steps:
1. Boot into bootloader aka fastboot - Hold vol- and plug the usb cable in.
2. Download this recovery.
3. Type "fastboot flash recovery <path>.img" (without quotes)
4. Type fastboot reboot, then immidiately unplug the usb cable and hold Vol+ to boot into TWRP.
5. Download B896_update.
6. In TWRP, choose Wipe -> Swipe to Factory Reset
7. Now, choose Wipe -> Format Data, and confirm
8. Advanced -> ADB Sideload -> Swipe to Start Sideload
9. In cmd (I assume you are using Windows OS) type adb sideload <path_to_b896_update>.zip
10. Once finished, in TWRP choose Reboot -> System (if the phone didn't reboot itself)
Let me know if it worked!
