No fastboot - Samsung Gear Live

Even though I can enter fastboot mode on the watch, a "fastboot devices" on the PC doesn't show the device.
Nothing has changed on the PC (drivers, USB cable, etc) since it last DID work.
This has happened previously but I could always get around the problem by simply entering recovery mode and then re-entering fastboot mode.
Now (because of a bad flash) my recovery mode has reverted back to the VERY basic one that only has 5 possible selections.
None of the menu entries provide direct reboot to fastboot mode (which if formerly did).
So, my "trick'' mentioned above no longer works.
A separate issue is that the version of software I (accidentally) flashed is known the be unable to pair thru bluetooth to the phone.
I LOVE this watch, but they are getting harder and harder to find a replacement (if I can't get this one recovered). SO PLEASE try to help.
Boowho??

I'm sorry to revive this post, but the issue is pretty much the same as the above issue. It boots up normally, isn't visible in bluetooth, shows up as Gear Live in device manager, shows up as "unauthorized" in Restore Tool, will not reboot into fastboot using either the tool or the command prompt, and doesn't show up when manually put into recovery/reboot. I have read every post I can find (many of them multiple times), did everything I can to my drivers, and bashed my head into the wall too many times to count. Any help and/or advice is greatly appreciated.

[Q] Bootloader Troubles

Last night I was on my nexus before I would go to bed. I opened the franco kernel app and then noticed that r6 was available for download. I downloaded and flashed it and was about to go to sleep when I noticed the notification light that my phone was charging. I thought it was neat then tried to get some sleep, but my promised sleep did not come quick. After a good chunk of time had passed, I thought that my lack of sleep was caused by the green light that was barely noticable. I searched and searched in the app to try and find an option to disable the LED, but could not. I then decided that the best way to get rid of the light, would be to flash the older r5 kernel so I wouldn't have to see the light anymore. I hit flash and my phone rebooted and then brought me to the bootloader. I attempted to reboot but I could not. I've tried using adb and nexus root toolkit to get my device to work again, but they can't seem to find it without the correct drivers. I installed Motorola device manager, nothing. I tried to follow the instructions in the toolkit to get the correct drivers installed but I can't continue with the need to enable debugging, which I cannot do from being stuck at the bootloader.
Under bootloader logs, I have the following messages:
Invalid boot image size!
failed to validate boot image
Fastboot Reason: Fall-through from normal boot mode
Any help would be greatly appreciated.
USB debugging is an android setting. It can only be used when android is running. If you had USB debugging on, it would make absolutely no difference in recovery or bootloader so don't let that step stop you.
From the logs, it sounds like your kernel download is corrupt or didn't flash properly. I had a similar message when I flashed a partially downloaded recovery image today.
Just fastboot flash a complete boot image
I tried that last night by launching adb and doing 'adb devices' but my device is unrecognized and I am unsure of how to go about fixing that.

Tried what exactly? Adb and fastboot are two different things. Adb works in android or recovery only. Fastboot works in boot loader only. Boot to boot loader and do "fastboot devices"
Ah that was my mistake. But the fastboot devices command just returns a new line for a new command to be entered in

That probably means there is a blank line between them - showing that no device is found. Unlike Adb it just gives a blank line instead of "no devices".
Probably means a driver issue or cable issue. Try different USB ports / cables if you can. Check to see if there are any yellow triangles in device manager too.
I'm new to this phone so I don't know where the drivers are if you need them. If I ever find them, I'll port my nexus 5 Adb and fastboot thread over here. Unfortunately i use Linux at home so I don't really have a driver issue.
Oh, so if I were to use Linux I wouldn't have to deal with missing drivers? I'm assuming that's the issue since no matter which port I use, 'Connect USB Data Cable' doesn't change

I can't say for sure. In Linux you may need to add UDEV rules. I didn't though. My bootloader is just recognised.
Please do check your device manager though.
I'm sorry i can't help more right now. I'm going to bed.
Okay, thank you! I'll reply if I encounter any other errors!

Oddest Brick Ever - Kindle Fire (Tate)

History of the issue at hand:
I was running a new rom that was marshmallow based. It was running fine but lost root privileges so I attempted to boot into recovery and install the stable version of SuperSU for the device. I wiped the dalvik and cache and rebooted through TWRP recovery and the system went into a bootloop. Solution: Read XDA forums to find a way to fix the device. Went on ebay and bought a fastboot cable, waited 3 weeks, cable comes in and gets me to fastboot mode, but I am running Windows 10, creating a new problem. Solution: Partition the HDD on my computer and install Windows 7 Professional. This now fixed the driver issue. Plugged in the cable, with the new drivers installed and voila - Fastboot mode.
Seems pretty easy right? Wrong. After trying several utilites, I still cannot seem to get the Kindle to get out of the current situation it is in.
The device was rooted with the 2nd bootloader added over 2 years ago. Every ROM I have ran has been successful. Every time a new ROM was used or tried a backup was done and the device wiped properly before install. I made sure that every ROM was for my specific device (Tate).
Here is what I can do:
If I power on the Kindle, it briefly shows the logo, then the fastboot logo and goes blank
If I power on the Kindle by plugging in the factory cable and quickly entering any command (it is already typed) like "fastboot erase cache" the system will remain in fastboot with the fastboot logo on the screen. My sdk does recognize the device and states it is in fastboot.
From here I have no idea where to go. I can type any command I like, such as erase cache, recovery, system or any multitude of things and the command prompt takes it time to show the device is working on the command. However, the device remains unresponsive and has the same issues when attempting to reboot. When flashing anything the target size of the device remains unchanged at 1006632960 bytes, which seems to tell me that device is receiving the command but not writing anything to the device. This probably also means that anything that is on the device causing it to continuously bootloop or fail is not being erased or properly formatted.
All I have is fastboot and time. Time to scratch my head and wonder if the device is truly and totally bricked. i am under the assumption that if I have a working fastboot that I should be able to at least accomplish something. Even if it means reverting it to bare bones stock and starting the whole process over. I will be happy to answer any questions you all have regarding the system via here or PM.
Please assist this old man and thank you in advance for your time.
Give it a try
While I wasn't in the same weird brick scenario as you. My device would show up on my pc as fastboot and or regular adb. But, I would get no video. The solution which I have no idea why worked was to pop the back cover off. Then disconnect the battery from the mobo. Wait a few seconds. Connect it back to the mobo. After that video showed back up. Then proceeded on my way.
Not sure if what I did will help you. But. Then again I didn't think simply disconnecting the battery and reconnecting it would solve video issues.
You definitely do have a weird brick scenario. Good Luck!

Solved: Can't pass fastboot commands to bootloader

Hi guys,
I've got a real head-scratcher over here. I followed every guide to a T, but I can't get my computer to detect my device in fastboot.
I installed the Xperia companion. I tried to manually install the Google USB drivers, and the sony OEM drivers. Still, no matter what, when I enter, what is supposedly fastboot, it never shows up. When the phone is on ADB devices shows it just fine. I am at a total loss!
To enter fastboot, I am shutting down the phone, pressing the volume up button, and plugging it in, then I get a black screen and a blue LED, which supposedly is correct? I've personally never seen anything like this before. Device manager does detect it as an unknown Android device, however, if I try to apply any drivers to it Windows simply informs me I already have the latest ones installed.
Thanks
SOLUTION: It was a driver issue after all. Windows 10 would not detect any drivers, nor let me install any drivers manually from files, however, it did let me select built-in drivers from my computer. YMMV, but If you are running into this issue try this:
1) Put your phone into bootloader mode.
2) Open device manager.
3) Right-click the device called "Android" with the yellow question mark, and select "update driver."
4) Click the "Browse my computer" option.
5) Click "Let me pick."
Note: There are several categories here, I suggest you try them all: portable devices, android devices, and in my case, Samsung devices. In one of the categories, you will find Google listed as a manufacturer.
6) In one of the categories, you will find Google listed as a manufacturer (in my case it was under the "Samsung Devices" category).
7) Select Google and then select the newest fastboot driver listed (in my case it was dated 2016), and install that driver.
8) Go back to PowerShell and run "fastboot devices." With a little luck, it will work!
Previous steps:
Edit: I had the thought of trying
Code:
adb reboot fastboot
and that got me into fastbootd, and then my PC detected it, however, the phone did not accept the unlock command.
Code:
FAILED (remote: 'Unable to open fastboot HAL')
fastboot: error: Command failed
I rebooted into the bootloader from here, got the same black screen, blue LED as above, and my phone is still not detected by fastboot.
Make sure you open cmd window in fastboot folder...i hope this is help
Sony fastboot mode is different I think. It was odd to me but doesn't show anything on screen when I went to fastboot to flash US firmware

I live in Boston and got the the XQ-AT51 (despite the fact that B&H was originally selling the 52... so in a few months I'm going to have to flip this phone ), do I have to reflash a stock firmware before I can unlock the bootloader? I do have it from XperiFirm.
Edit: This was dumb of me as you can't flash anything onto the phone unless the bootloader is already unlocked.
Edit: I don't want to double post, but I managed to solve the problem, and added the solution to the OP.
THANK YOU VERY MUCH FOR THIS GUIDE. I was struggling for hours on end with the "Unable to open fastboot HAL" error message, but followed the steps outlined in your guide a little differently than you, since I'm on windows 7. I believe that the root cause of my issue was that I actually used the down volume button instead of the volume up, believing that it was weird for the screen to show nothing except for the blue notification LED.
Here is what I did just in case for people who might encounter the same issue in the future. Be warned though that I'm not an english native so the options won't be accurately translated but I'll try to do my best nonetheless.
1) Put your phone into bootloader mode (volume UP + power button, not down.) Don't be afraid if nothing shows up, it's actually normal
2) Open device manager
3) Right-click the device called "Android" with the yellow question mark, and select "update driver."
4)ISelect "Look for drivers on my computer (manual install option)
5)Select "Choose from a list of drivers installed on this computer"
6)Scroll down through the manufacturers and such until you find "sony sa0200"
7)Install it
Normally everything should be working fine with fastboot. What a relief
I have a similar problem, but my device manager does not show any android device from the bootloader. I've tried multiple cables and everything works fine in adb mode.
EDIT: Nevermind. It ended up being multiple bad cables. They all worked in ADB/booted but not in Fastboot/bootloader. Tried one more it it worked completely
I have same issue with my Poco X3 Pro, the device working fine and is recognized as ADB composite when i'm under MIUI, but when i launch the device in fastboot mode, the ADB composite disappear and a generic "android" device appear and i'm not able to install any drivers, no qualcomm, no xiami, no generic google usb, nothing.
Following the tips above, nothing work. I'm under windows 7.
Any tips?
Thx everyone for pointing me to the right direction. Flashing latest twrp was the final step. Recovery is back to now .

Alcatel 1C suddenly says "can't load Android system"

I've ran into the following problem:
came home and try to open my phone, code doesn't work to unlock screen. Unless I'm going insane was sure the code was correct twice.
Restart phone, stuck on enjoy.now for a long time, goes to alcatel logo, then goes into an Android Recovery message saying "can't load Android system. Your data may be corrupt."
Then 2 options: try again or Factory data reset.
I've managed to find the following possible solution: https://glebovdev.medium.com/how-to-fix-cant-load-android-system-issue-8a5b0ead5a15
..but I can't even get to recovery screen with more than 2 options. It would be a huge pain if I have to factory reset.. should it be possible to get to recovery mode on my phone as well?
Is there any possible way to get the data off the phone (mainly Google Authenticator to which I'm not sure I have the codes anymore)?
Thanks

It could be that your device is trying to boot to the inactive slot, verify in fastboot mode which slot is marked as active and try to boot either in A and/or in B slot.
Idk if I'm doing something wrong but holding volume up or down as it restarts, the only boot screen I get is:
Android Recovery
TCL/5003d_EEEA/Curie
8.1.0/OPM2.171019.012/5003d_ALWE_EEA_V3
user/release-keys
(aforementioned error)
Try again
Factory data reset
fastboot mode should show other options right?

Well, fastboot is to interact through fastboot commands and you can check from there the slot that is active with
Code:
fastboot getvar all
and you see something like slot_active xx
When I run adb devices in powershell it does not show any devices connected (although the device does show as connected in Windows device management).
In device management it does show as "MTP USB device".
Is this likely to be a driver issue?

Device has to be power on to respond to adb commands and from what you were telling your device is bricked..
It's technically powered on but yes still does nothing but bootloop and try again/factory reset screen. There's no possible other way to get to Android recovery mode when the volume down+power option doesn't seem to be working?

Device has to be strongly and consistently on so adb commands can work, they can't work while in bootloop so forget it this way.
What you can try is tipically pwr + vol. up and pwr + vol. dwn, one of them will take you to fastboot mode where you can give it a try to what I pointed out in previous outputs.
OK some progress.. apparently you have to let go of power button and volume up right as the alcatel logo appears, the timing seems to matter. I'm now able to see Android recovery with more options at least so will try from there.
Thanks again for taking time to reply.
I've tried
Code:
fastboot getvar all
this results in <waiting for any device>
adb devices still shows no list of devices even though in Device Manager it shows as "Fastboot gadget" under other devices
I've downloaded drivers from Alcatel website in case it's a driver issue but on the list of model numbers during setup mine (5003D_EEA according to recovery screen) doesn't show.
I do see a bunch of websites allegedly offering these specific drivers but assume it's risky to download from anywhere other than Alcatel official site.

It seems to be a reliable site https://www.androidusbdrivers.com/alcatel-1-usb-drivers/ it offers the 4 different drivers needed covering all the modes that your device can enter to.
I would recommend mainly two things:
- Uninstall/remove firstly all the drivers that you don't use, it could be something for an old android/tablet that you don't use anymore.
- Don't swap the cable data from/for other device, any of them have its own type of connection, use the same proper cable data for only one device.
From there the typical first step in fastboot is just typing
Code:
fastboot devices
], if the message is "waiting for device" then it's not working.
hi im having the exact same problem, but cant get out of this. Could somebody maybe help me? How did you eventually fixed it? kindregards

Question Stuck in bootloader by attempt to install lineage os. How ****ed am I?

Hey, dear community,
First of all: I'm using Linux. The Version of Fastboot is 33.0.3p1-android-tools. The device I thought I'm experienced enough to install Lineage OS on is the Asus Zenfone 8. Yes, I asked google - for hours. And I think I am really ****ed now.
Cause the Smartphone (Asus Zenfone 8) was not cheap. And it does not boot anymore. I don't get in Recovery mode anymore. And I'm not able to connect via Fastboot anymore.
But let's start at the beginning.
I was pissed, cause my smartphone forced me to use google. Even if I skipped the Google-Part in the setup, it forced me to agree to send Google information. And I read it. They (quote: may) send Google **a lot** of data. Data I don't want to share - and I don't need to share IMHO! I didn't like to use such a intransparent Device anyway - but this convinced me to try this thing named LineageOS.
I thought about myself I am not a bloody beginner. I mean, I use Linux as my daily driver - for years. And my phone (Asus Zenfone 8) was in the list of supported devices - so I had to try it. I thought if I just install these tools, adb and fastboot, and do these things in the wiki carefully, step by step, what could happen?
And it worked. It worked to unlock device, to connect via adb, to connect via fastboot. It worked to flash the vendor_boot image, It worked to flash the recovery image. But then, just before I wanted to start with the "Installing LineageOS"-part, and therefore boot into recovery mode - it didn't work. I was stuck in the bootloader. I am. still.
There are the options "START", "Restart bootloader", "Recovery mode" and "Power off". No matter what I try to enter, the device restarts (at least it looks like) - It shows "Powered by android", and then the bootmenu again. And again. And again.
When fastboot was still connected, I tried to flash the images again. I even tried to boot directly into the recovery image using `fastboot boot image.img`. But it did not work. And then, the device even stopped showing up when I ran `fastboot devices` - it disconnected.
"Power off" is the only option, wich still appears to work (when not plugged in).
What should I do? Is it even still possible to do something? Please help me.
PS: It would be nice if you tell me, wether the tools or guides you recommend to me work on Linux, in a Windows VM or only Windows Bare Metal. I will do everything to bring my phone back, but it safes a lot of time, not to try using a tool in Windows VM if it only works bare metal anyway.
May be this thread could help you

Thanks, but my phone does not get into fastboot mode anymore, therefore I cannot connect to my phone via fastboot to flash new images.

I had the same problem. Only bootloader with no device showing with "fastboot devices".
Luckily I tried another cable. An Apple USB C cable behind a hub (screen) got fastboot working. Then I flashed android 13 beta.
And I am sure the other cable worked before with ADB and fastboot.
Try other cables and USB ports... Good luck!
