***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!
I have unlocked my phone, hoping to find a fix to USB external camera not being recognized. As a consequence, I am not able to update my system through OTA. Moreover, I am no longer able to enter fastboot mode. Whatever key combination I tried, my phone will do a normal boot. When I power up or I press volume - I only end up doing a normal boot or powering off. If I press all 3 keys together I get into the e-recovery boot, which fails. I have only been able to boot into TWRP after downloading a system update and choosing to install it. With this procedure, the update will not be installed, but I will boot into TWRP. From here, if I choose recovery, I do boot into fastboot, but my fastboot is not recognized by my computer, as it was before. Running either ADB or Fastboot will not reveal any device connected.

When you use key combinations, you must shutdown your phone first, not reboot or you can boot into system, make sure that usb debugging is turned on, open adb and type "adb reboot bootloader".

Thanks, I followed your instructions but with no success. As soon as I plug into USB it will power on and go on with a normal system boot, no matter how quick I am in typing the command "adb reboot bootloader", which invariably returns "no devices/emulators found", or whether I press the volume - button or not. This also happens when I am in the charging screen (not sure whether this also equals power off).

No, you need to boot to Android to use adb.
Is your device bricked or stuck in a bootloop or something?

I wouldn’t call it properly bricked, inasmuch as it is actually doing its job. However, It does some strange things: it gets the OTA updates, but when I click on Download and Install, it restarts in the TWRP menu (which I cannot otherwise access. I have 2 TWRP apps installed, which don’t seem to be of any use: official TWRP App and TWRP Manager). When I am in the TWRP menu, I can choose to restart in the bootloader. However, once there, with the green window telling me that my phone is flashed, the phone is still not detected by ADB or Fastboot commands. I don’t know when the bootloader started to be unaccessible because I left the tinkering a couple of months ago, when I realized that nobody so far has had any success in getting a P10 Lite to work with a USB Endoscope.

Thats normal behaviour, when you have a custom recovery installed and do anything in the stock recovery then it boots you into the custom recovery, it should also boot to TWRP when you do factory reset in the stock recovery. And when your phone isn't detected by fastboot then its probably a adb and fastboot installation issue on your PC, type "fastboot devices" to see if it detects your device. And what do you even want to do in fastboot?
Also are you in Nougat or Oreo?

I am not too sure to have any working recovery at all, right now. If I press all 3 buttons, I get into the Huawei recovery mode, which fails. I am on EMUI 5.1.1 (Nougat) and would like to install a stock recovery to Oreo. If I am able to get to a working bootloader mode, I would like to install this file which seems to be a stock recovery with Oreo (WARSAW L21C432B182_EU_SERVICE_ANDROIDHOST.RU.RAR). Otherwise, I will buy a MicroSD card reader and try copying this installation to the card, which, according to this video (https://www.youtube.com/watch?v=0vDgDXePAR4&feature=youtu.be) should be the last resort, if everything else fails. I would be perfectly happy to return to a working and updated standard EMUI. I'm told that if I installed the OTA version this would not be working correctly on my my phone. According to an app called Rootchecker, my phone is not properly rooted either, but there are a lot of crappy apps out there, so I don't know what to believe.
BTW: I don't believe there is any problem with my adb fastboot installation (on MacOS). It was working earlier on. When I type "fastboot devices", it returns: "waiting for any device"

I still can't uderstand you. Can you boot into Android or not? And Does TWRP work? When you device is softbricked, what did you do to brick it?
At one point you say that you can access fastboot by choosing reboot to bootloader in TWRP and then you say that you have no working recovery at all.
Anyway I can't help you with the fastboot thing then and that file isn't Oreo it's an old version of Nougat, B360 and up is Oreo and also B321 witch is Oreo Beta. You can only flash image files in fastboot anyway as that file needs to be unpacked and put on the dload folder on your sd card.
When you want to get to Oreo you can either use service roms from this thread https://forum.xda-developers.com/p10-lite/development/service-rom-b362-c432-upgrade-o-o-n-o-t3813946, you need to copy the two zip files into the dload folder in your SD card. You can also use HWOTA but that wouldn't work since fastboot isn't working for whatever reason. Or when your custom recovery is working you can use HuRUpdater. But you need to be on the newest version of Nougat B210 or B209 to update as otherwise you may brick your phone.
Hello,
Today I got a prompt to update Android to 8.0.0. Not sure why this came for the first time only now, I've been on version 6 for over a year.
After updating I got a notice that data was corrupt, and I must either retry recovery mode boot or factory reset.
Needless to say I don't want to reset and lose all data.
I have downloaded ADB and rebooted into Bootloader but cannot get the device to show up in my PC in order to backup data.
while in bootloader adb devices returns no results
fastboot devices returns my devices serial ## fastboot
however, when I try to enter recovery mode I just get the data corrupt loop again and ADP can't see anything.
d I'm not sure what the correct fastboot command is to backup or create an image that will allow device to boot.
If I use fastboot to load a flash will it wipe my user and app data? are there any other options to make a backup?
Thanks!
UPDATE:
After holding down power button for 15-20 seconds got a longer boot cycle. then going into boot loader and selecting Recovery Mode twice in a row I was able to get into normal recovery mode with full options. now trying to wipe cache and sideload using ADB but no resolution yet.
Note ADB NEVER showed my device when queried, even though it showed up in fastboot, but if I unplugged and plugged the USB and then just ran the ADB sideload command it is working.

OPR6.170623.019 does not work
OPR5.170623.014 does not work
Tried OPM6.171019.030.E1 based on above link. IT WORKED!!
suggestion: go with latest build not your current which is causing issues.
Last week i received a notification the 8.1 Oreo update was available for my Moto g4 Plus.
Downloaded the package and hit the install button. My moto restarted in order to perform the installation.
However, since i had TWRP installed and thus bootloader unlocked, the phone restarted in recovery mode.
Downloaded a TWRP 8.1 rom and installed it without a problem.
Unfotunately everytime I restart my Moto it starts up in fastboot mode.
Bootloader log shows: Fastboot Reason: reboot mode set to fastboot
From bootloader I can start the Android OS, but i wan't to get rid of this reboot mode
I tried tools like "Android Multi Tool" and "Free ReiBoot for Android" but this reboot mode can not be cleared.
Anyone encountered this problem and how did you fix it.
Thanks in advance
Try this:
Reboot your device to the bootloader.
Connect your device to your computer and open an ADB terminal on your computer.
In the ADB terminal, type 'fastboot devices' without quotes. Press Enter - your device should respond with its serial number.
If so, then type 'fastboot oem fb_mode_clear' without quotes. Press Enter, then reboot your device.
That fb_mode_clear command seems to clear a flag that keeps your device booting into fastboot (usually for OTA updates).
I have Tried that option as i found it as one of the possible solutions for this issue.
the clear_fb unfortunately does not remove the fastboot mode on my moto.

Alright, though this is for solving TWRP bootloops, might be useful for you https://forum.xda-developers.com/moto-g4/help/troubleshooting-twrp-boot-loop-ota-t3714325

echo92. Thanks. Works like a charm. Issue fixed.
Several months back I encountered the error "E:[liblp]Logical partition metadata has invalid geometry magic signature." when trying to apply updates. I've been unable to apply updates since that time, which has concerned me.
Yesterday I noticed the release notes for a multiple month old release of Lineage Recovery stated the "Logical partition metadata has invalid geometry magic signature." error had been fixed. It made reference to returning to stock to upgrade.
Last evening I downloaded the stock rom for this device and installed it using ODIN. All is well.
I would like to put both LineageOS and Lineage Recovery back on the device. Unfortunately, I can't enter Fastboot. When I use either the key combinations or "adb reboot bootloader" I see the text "Entering Fastboot..." on the display of the device, but nothing more. I've let the device sit for about five minutes without any change. It's definitely not in fastboot because "fastboot devices" shows nothing. "adb devices" shows the device when it's in recovery, I just can't enter fastboot.
Has anyone seen this problem? I've tried wiping cache and system using the Samsung Recovery (which overwrote LineageOS Recovery when I installed the stock rom) without any improvement.
Thanks,
Bob
I've got the same issue. Anyone can help here.?
You are NOT supposed to ever use adb reboot fastboot. EVER! Always use ODIN mode.
If I remember correctly, do Samsung devices even have fastboot?
They don't but Samsung added a what's basically a dummy version of fastboot that does nothing.
Try using the key combowith the tablet connected to your PC. That got me in recovery mode and from there you should be able to go into fastboot.
The whole point is not to use fastboot LMAO, because fastboot on modern Sammy devices is just a dummy version.
