Rom: Stock
Rooted with KFU 0.9.5
TWRP 2.1
fff 1.4a
The problem I'm having is that when I boot my KF up it goes to fff. I get 3 options to boot from (this is whenever I power down the KF). When I choose to boot to recovery, the power light turns orange for two secs and then it boots; but back to the fff screen. I did this about four times in a row and it still boots back to the ffa screen.
If I choose ~normal boot~, It boots up fine. When I try to use KFU to boot to recovery or fast boot, it says that it is waiting for device. I tried this several times but no luck.
I want to get into recovery. That's my goal. I'm guessing that the KF is not booting in fastboot for it to go into recovery. I tried to reinstall TWRP 2.1 with KFU and it gets to the point where it's waiting for the device and nothing happens.
I'm not very advanced in this stuff. Please be patient with me. Thank you for all your help.
what command are you using to install recovery?
ok
download twrp 2.1.1.img onto pc
turn off kindle (20 second hold) with the usb cable unplugged from the kindle
open terminal where you have fastboot located.
type the following:
fastboot flash recovery </enter/path/to/recovery.img/here>
press enter
you should see waiting for device
then plug in your usb to kindle
this should power up the kindle and fastboot flash a new recovery.
then type
fastboot reboot
note:
(there is a space between recovery & /
i also find it easier to put a space after "recovery" then drag & drop recovery.img into terminal)
ok...
I did everything you said and the cmd console was still <waiting for device> after I plugged in the KF.
I checked in device manager and that's ok for the adb (it says: android composite adb interface).
Still looking to get into twrp recovery.

There's probably something wrong in KFU's process. Could you at least show us its log or a screenshot?
reflash twrp using smirkit. than try to get into recovery again
Sent from my Galaxy Nexus using xda premium
if its waiting for device your pc is issuing fastboot command. so as you say its your kindle.
one of the above methods should work.
imho smikis's smirkit is nice to use
edit: can you copy and paste your commands after you try to flash new recovery
***FIXED***
Update:
I was able to resolve this, here is what I've done in case others happen to have the same issue:
Turn on computer volume, reason being I had mine off and even though it appeared to skip over fastboot with the OTG method, it in fact was enabling for a sec or 2 then moving on as I could hear the USB connection chime.
NOTE: I had to press and hold to the LEFT of the Nvidia symbol until I heard the USB pick up chime, once I heard the chime I released my finger.
Prior to plugging in the power cord, I ran "fastboot boot <yourfilename.img>" and it sits at waiting for device...
Device took it and booted me into TWRP, I then flashed the Unofficial TWRP for the SATV, by choosing Image, then finding the .img that I already had on the internal storage
Rooted with SU, rebooted system and everything is now good to go.
Root, custom recovery and also Fastboot stock menu is back.
---------------------------------------------------------------------------------------------FIXED------------------------------------------------------------------------------------------------------------------
Hello All,
Long time lurker, now reaching out.
Just looking for a little help with my SATV Pro 500gb.
Here is the background:
Out of the box today, booted up and enabled ADB and jumped into fastboot for the bootloader unlock
Process took about 2 hours as the info said it would. Device rebooted, perfect working order.
Decided to flash TWRP for SU install along with possible custom roms, etc.
used this tool:
http://forum.xda-developers.com/shi...l-windroid-universal-android-toolkit-t3291266
Device said "please wait...." in fastboot screen, appeared finished and device rebooted into the the OS.
Here is the problem:
I go into command and adb reboot-bootloader, device reboots, I see the Nvidia logo and it boots into the OS, skips right over Fastboot
Shut it down, attempt the OTG, power cord ~3 secs over and over, hangs at logo and then boots in to the OS.
I reset the device, hoping the recovery OS would reflash the fastboot image, appears not to be the case.
Currently I am stuck with no fastboot access, device boots to OS no problems, but as far as fastboot is concerned I cannot access. Appears something went wrong with using that 1 click tool for flashing recovery.
Now before anyone chimes in, adb reboot-bootloader will not boot into fastboot and I've attempted the HW method listed on Nvidias dev site. Its 100% nogo.
Current State of device:
No fastboot
OS boots no problems
ADB works
No Root
Thanks for everyones look and help!
Hi,
Today I wanted change my recovery. I had the Lineage OS recovery, but i was trying to install the twrp recovery.
So, the guide of twrp says that you should boot the twrp via fastboot boot twrp.img and install via the booted twrp. But I mistaken the command and I wrote fastboot flash boot twrp.img, I tried to reboot and the device booted himself in fastboot with the enter reason "error boot prepare" and I can't boot into the system or recovery.
I tried to flash the official image downloaded from the Google Developers website, but when i run ./flash-all.sh, console get stuck. I waited for about 15 minutes but nothing. I tried even the official Android Flash Tool but after 10 seconds it says "Your device stopped responding. You may have to select restart in the bootloader menu in order for it to be recognised again."
Does anyone know how to help me? Thanks in advance.

Yes, I wrote in the post, I tried both the command line tool and the chrome version. Btw i'm on linux
Okay so, I fixed.
For anyone who will have this problem you just need to flash official Android 9 and next Android 10. Only with Android 10 you can use fastboot flash boot recovery.img (you can't use twrp in android 10 with the Pixel 3a)

It depends if your pc were authorized, if it was, you can use fastboot to flash the stock version of Android 9, just running the flash-all(.bat) script.

I'm not certain I understand what you mean by PC authorized? I'm using a Windows 10 tablet. When the phone is attached to the computer it sees it as a device that can be disconnected through USB.

I just had an encounter with this. I was rooting my device (Pixel 3A) and messed up my partitions through accidentally attempting a downgrade which broke all my ****. I was unable to easily reset this device to factory, so it took me several days to figure out and root. I'm getting better though as a hacker, because a year ago this would have taken me a month.
I was able to enter recovery mode (lying down Android, NO COMMAND). From this recovery mode, adb devices -l recognized my device, although I was unable to get a shell.
At first, ADB was telling me the device was authorized, but I messed with a bunch of other stuff (tried to flash a bunch of different partitions and monkey around in general trying to install Magisk) and then ADB started telling me it wasn't authorized when I used devices -l.
Once it said unauthorized, I was unable to issue the device any commands with ADB, so I just used hardware keys to get into recovery mode. From there, I selected OTA update, and it got into sideload mode. At that point, I used adb sideload with the OTA package that I downloaded here https://developers.google.com/android/ota
^^^ That operation did successfully restore my device to factory
This following guide here describes the details of how to use hard keys to enter recovery on this phone (don't download anything from there tho, and make sure your adblock is on)
How to Hard Reset your new Google Pixel 3a [Tutorial]
In this article, you will learn how to start your Google Pixel 3a up into the Recovery Mode and perform the Hard Reset to make it work perfectly again.
thedroidguy.com
I just wanted to say, I've been wrestling this hardbrick for a couple of days with my Pixel 3a.
I've finally overcome it by sideloading the most recent OTA update after using a hard key combo to get into recovery mode. The hard key combo is hold Power Button, tap Volume Up, then release both. Then, all you need is to use the command:
adb sideload <OTA.zip>
^^^OTA wasn't the actual filename though, you can download OTA packages for Pixel 3A here: https://developers.google.com/android/ota
the OTA binaries are NOT the same as the factory images, which is here
Factory Images for Nexus and Pixel Devices | Google Play services | Google for Developers
developers.google.com
Sideloading the OTA package brought my phone back from only having fastboot and recovery mode, even when flash-all.sh from the official downloaded firmware failed. Now I know how to undo damage that I cause by rooting this thing. Since I sideloaded newest firmware, it was also like applying an update. I easily got root after that, and I've logged the process. I'll make it into a guide soon
I'll just note that if you accidentally flashed the TWRP boot image instead of simply booting into it, I believe all you have to do is flash the stock boot.img to fix the problem. Obviously you can sideload the entire rom image, but that shouldn't be necessary.
Using the Windows computer (or whatever computer you are sending ADB commands from), download the full stock image directly from Google. Unzip it and then upzip the folder inside. You should find the boot.img file inside that folder. Take that file and then flash it to the phone using the normal ADB command: fastboot flash boot boot.img
While I haven't tried this myself recently, it should work in theory. The command "fastboot flash boot twrp.img" flashes the boot partition with a non-working twrp image, so replacing the faulty image with the stock boot.img should fix the problem.
If I did the same I would first attempt to manually put device in bootloader/aka fastboot mode then fastboot flash the stock boot.img , sudo fastboot flash boot boot.img --slot all
I only read the op (first post here);but I betcha that would have worked. Then sudo ./flash-all.sh and let it do it's thing.
Recently, I purchased a TicWatch Pro 2020 (saw that Kali Nethunter now seems to work on it and I thought it could be a cool device to add).
I have installed nethunter onto several other devices already (Nexus, OnePlus, etc.) and of course ran into issues. Usually I spend a long time on them and it is fun to do it. But I seem to have run into a wall recently with the watch.
When I was first trying to set up the watch, I could send commands with adb to get it into the bootloader menu but then it would not recognize it. I did eventually get the right drivers installed and had my VM recognize the watch with the ADB drivers.
I did manage to complete Step 1 of the tutorial https://www.kali.org/docs/nethunter...-on-the-ticwatch-pro/#1-unlock-the-bootloader
(unlocking it).
I went through to step 2, put it into bootloader again and flashed the vendor and twrp .img files. Once I did this, I tried to switch the device into recovery mode (after it went back to the bootloader menu on its own) as per instructions. But the weird thing is when I initialized recovery mode, it just sent me back to the bootloader menu, all while also not recognizing it on my VM/PC at all. When I tried to start the watch, it just sent the device into a permanent loading loop (after showing the logo and cycling the 4 different colored Google dots around the watch). I can get it back into the bootloader menu by holding both buttons down but I can't get my device to be recognized with a data connection (so it seems effectively bricked).
Normally I look this up myself but since there is not much information regarding this device and this specific rom out there just quite yet, I can't locate anything (compared to troubleshooting the OnePlus 7 Pro). Any ideas or input is appreciated!
Edit: will just let it run over night (drain battery to see if it may or may not help).
Thought I would leave a quick update in case you may be running into this issue yourself.
I let it run over night and run out of power to see if it would do anything. It now seems to be recognized by my pc, but it would not connect. I am installing everything through a VM but it appears that the PC could not recognize the device (I only had drivers installed on my VM, not my main device). When I installed the drivers on my main desktop it began to recognize it again on my VM. Not sure why this was an issue or how it became one or if it was a combination between everything but now at least I can send adb and fastboot commands to my watch again. Will try to flash a stock rom for it and try again to get out of the boot process (still confused as to why it will not go into recovery mode but it instead goes back into boot loader mode when I select it)...
Another update: I managed to find a stock image and some simple instructions. Credit to @sonnettie as it looks like it is working atm (going through setup).
Link: https://forum.xda-developers.com/t/ticwatch-pro-2020-stock-image.4107539/
Going through to try installing nethunter again if it appears to be fully functioning.
Edit: Using the stock image seems to let me now use my watch again. But whenever I try to install Nethunter, I install the vendor and recovery image. Once I do this and try to go into recovery mode, it just seems to bring me back to the boot loader menu. Anyone have solutions or know what is wrong?
i got nethunter and twrp working on the ticwatch 2020, it was a pain finding the right files to use and i soft bricked my watch many times in the process.
https://forum.xda-developers.com/t/...shark-4g-ticwatch-c2-skipjack-9aug20.3821013/ this post has the right vendor.img and twrp recovery image, in particular this mega folder https://mega.nz/folder/cVVBRaxL
1-Vendor-Images-22-Jun-2020.zip unzip this file it is located in TicWatch-Pro-2020(Catfish-ext)/Custom-ROM/ROM/22-Jun-2020 it contains the vendor.img you'll need
tic-watch-pro-2020-twrp.img in TicWatch-Pro-2020(Catfish-ext)/Custom-ROM/TWRP this is the TWRP Recovery.img you'll need
Magisk-v21.0.zip and nethunter-2022.2b-ticwatchpro-wearos-kalifs-nano.zip are both needed from the TicWatch_Pro_NetHunter_files.zip at https://build.nethunter.com/contributors/re4son/catfish/
1) Enable ADB and unlock bootloader then enter these fastboot commands on pc
fastboot flash vendor.img
fastboot format userdata
fastboot format cache
fastboot flash recovery tic-watch-pro-2020-twrp.img
2) Reboot into WearOS and Setup Watch
3) Enable ADB again and reboot into recovery
adb reboot recovery
4) move Magisk-v21.0.zip into the TWRP folder on the watch
install Magisk-v21.0.zip from TWRP recovery (it'll patch the boot.img itself)
5) Enable ADB Sideload from the Install menu in TWRP
adb sideload nethunter-2022.2b-ticwatchpro-wearos-kalifs-nano.zip
6) Reboot into wearOS with kali splash screen, you will have to open the magisk app after you open the nethunter app to give it root as there isn't a proper pop-up screen to give root access
**circle screen does semi cut off a few buttons in the nethunter and magisk apps, touch your watchface close to the "corner" where it is to select it
I hope this all helps! Cheers mate

i just realized i typed all the above and didn't reply to your message, it was a mixture of two install methods with leaving out the flashing of the rom file itself
Hey guys, I know this isn't super active anymore, but I tried looking and tried posting elsewhere, and I can't find the answer I need. I'm sure it's something super simple I've overlooked.
I was gifted a 2015 Nvidia Shield TV Pro that was never used, so when I turn it on it gets stuck forever asking for my google login and won't proceed (like this thread here).
I can access the fastboot menu on the unit, and I've installed the PC drivers - BUT
When I open command and type "adb devices" it shows no devices connected.
I'm TOLD this is because I need to activate USB debugging on the unit, but how can I toggle on the USB debugging if I can't get past the google sign-in for a first-time set up?
Am I approaching this wrong?
PLEASE help!
Hello, I have exactly the same issue.
I would be really grateful if someone could help us.
i think you must set your SHIELD in FASTBOOT mode and after flash the stock firmware from https://developer.nvidia.com/gameworksdownload (you can't set FASTBOOT mode from ADB because of the wrong login)
to set fastboot mode look here : https://nvidia.custhelp.com/app/ans...invoke-the-android-fastboot-menu-on-shield-tv
Thanks conduisant! It helped.
I have spent some time to flash new recovery:
How far I was able to proceed:
I downloaded ADB Fastboot drivers
I downloaded recovery image (nv-recovery-image-shield-2017-atv-8.2.3)
I connected Nvidia Shield 2017 (model: P2897) with USB-A-to-USB-A cable to the PC
I was able to see "unknown device" so I installed ADB drivers (SHIELD_Family_WHQL_USB_driver_201801)
In device manager I can see my shield (as a Android Bootloader Interface)
I can access fastboot (pressing A+B on controller during turn on of shield)
I opened CMD and type "fastboot devices" - press enter - I can see my device is listed "03xxxxxxx fastboot"
I am able to execute "fastboot oem unlock", so bootloader is unlocked
I am able to write recovery image by using following commands written in instructions:
fastboot flash staging blob
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash vendor vendor.img
fastboot oem lock
fastboot reboot
(no errors, everything was "OKAY")
But after the device restart , I can post only until the nvidia logo and that is it. Unfortunately I do not even know which was the original (stock) version of system in nvidia shield pre-installed. I tried to flash several versions of recovery images, but nothing helped. I can still see only nvidia logo :-(
But what I noticed, my Fastboot looks pretty different. I do not see my bootloader version, also some options are missing (lock bootloader, unlock bootloader etc.)
I also tried another options - boot recovery kernel, safe mode, but only nvidia logo every time.What is strange, when I turn-on the device, the Fastboot is automatically booted (I do not even hold A+B to initiate fastboot) I need to select continue.
So now I am not even able to try login into the shield anymore. I guess I already bricked the device :-(
what you have done is pretty correct !
Shield seems to be hard bricked, you can also try to flash TWRP + lineage OS ROM only to see if the SHIELD still not boot...i've no other idea
Thank conduisant for your effort!
Unfortunately, I am not able to boot into the TWRP.
I tried to flash TWRP what I have found here on forum:
UNOFFICIAL-twrp-3.0.2-ALL-Shields-build2.zip
But no success.
I tried to also flash official TWRP:
twrp-3.2.3-0-foster.img
But also no success.
I do not know which offical recovery to flash before LineageOS ROM (or it does not matter?)
Unfortunately, for some reason my gamepad in Fastboot stopped working (gamepad is connectied via USB to the shield, closest to HDMI port)
It just rumble when Fastboot booted and blinks blue led. I tried to charge gamepad - or - another nvidia shield gamepad but it does not work.
Also USB keyboard does not work. Looks like the USB port does not work properly anymore, so I am not able to click "Continue" in fastboot anymore to post at least until nvidia logo.
Luckily, the bootloader is still unlocked, so I am able to flash anything but I have already lost my mind.
I need another coffee and one full-day of meditaion.
i've got 2017 SHIELD, and i've flashed this TWRP last days + this LINEAGE OS : and all working good
TWRP = https://eu.dl.twrp.me/foster/twrp-3.7.0_9-0-foster.img.html
LINEAGE OS = https://download.lineageos.org/foster
when USB debugging is ON, only one USB port is activate for USB devices (keyboard for example) : it's the port near HDMI, the other port (near fan grid) is for ADB connection for the PC
