i have a dell venue 10 5050 and i was messing around in the bootloader and now i cant boot back up to lolipop
i found a solution but i need adb and i cant get adb to detect the tablet. every time i do adb devices, i get:
"List of devices attatched
"
any ideas on how to get adb to detect the tablet? I have all of the latest intel drivers and android sdk
also, my bootloader is locked and the device is set to MTP, but i cant change it because i cant boot up to the OS
UPDATE: Im still unrooted with a locked bootloader, but i was able to boot into TWRP. I cant get ADB to authorize my device becuase the RSA Fingerprint window wont show up in TWRP... any ideas on how i cant get adb to authorize my device. I can get "adb devices" to say my device is offline or unauthorized.
also, im trying to unlock the bootloader and im doing "fastboot flashing unlock" and on my venue it says "RESULT: FAIL(unknown command)"
any ideas?

Should I be able to find my adb device while my phone is only booting to HBOOT 0.93.0001?
Been stuck on this for days...and it's killing me!
PS. When I plug my phone in to
PC it says "Android ADB interface installed" "Ready to use"
But when I cmd the adb to find devices "adb devices" it shows blank
P.S. Phone: HTC Desire
Unrooted
S-ON
Unable to boot, can only get to HBOOT.(so cant turn debugging on)
Trying to get a goldcard to flash a new rom and see if i can unbrick
Reason for unable to boot is - It had been rebooting itself for weeks, slowly getting worse, until now, when I cant get it booted at all.

adb won't work when you are in bootloader (It won't work until Linux is up). "fastboot" will work over USB in bootloader->Fastboot.
I believe RUU will work on fastboot mode.
I boot my Acer Iconia Tab A200 into fastboot mode (robot lying down and RED exclamation mark over it). I plug it into my Windows 7 (64bit) desktop computer with SDK installed, and from the directory with fastboot.exe I type FASTBOOT DEVICES but the device is not being seen, it just goes back to the prompt, like the command executed but didn't do anything. I assume this is because the drivers aren't installed. But I don't know how to install the "adb drivers". How is this done?
Go to Acer support page, you'll get the drivers there.
This device will not fully boot. It gets stuck at an "encryption unsuccessful" message. I'm trying to flash a rom image from my desktop computer using fastboot, but when my tablet is in fastboot mode, my desktop computer won't recognize it. ie adb devices command doesn't show that there is any device connected, and I think it's because the drivers aren't installed. I think those Acer drivers only work if the tablet can be fully booted.
Installed the Google USB Drivers from the SDK Manager already. Don't know what's wrong.
Alright I figured out how to get fastboot to interface with my Android tablet. The problem was that I wasn't getting the tablet into fastboot mode to recieve commands.
But now it's working. However, I'm trying to unlock the bootloader and it gives me an errors that says:
SetUnlockedMode: Error occured while unlock the device ...
Fastboot: Failed to set unlock mode
I have to unlock the bootloader before I flash an image to the tablet, right ?
Yep, surely.
I have a Zeki TBQC1063B Tablet with Android 4.1.1 on it. I am trying to see if I can unlock the bootloader so that I can try to put Ubuntu for mobile on it. This thing has been nothing but the bane of my existence all night tonight. I have made sure that while the device is on, the USB Debugger IS on, and I am using the correct USB drivers. In my SDK tools, I run the command adb devices and I get the following result:
List of devices attached
??????????????? device
For curiosity, I ran the command fastboot devices and nothing comes up. When I try to boot into "fastboot mode" it just comes up with a recovery screen with no mention of Fastboot. I am lost, confused, and very frustrated. Any thoughts?
I want to unlock my cousin's tab who recently passed away and no one knows the passcode so after some googling i found that you can do it via ADB.
(https://forum.xda-developers.com/showthread.php?t=2620456)
The device successfully connects with my pc but when I execute "adb devices" it shows;
.......................... unauthorized
and running adb shell shows;
This adbd's $ADB_VENDOR_KEYS is not set; try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.
With the device locked Im unable to authorize my computer so I decided to search something for that too and found this article where it tells u to pull keys from another device and push it into your locked one while in recovery mode and this is where Im stuck. Whenever Im in recovery mode, adb devices shows nothing so if someone of you could help me would be awesome.
Hello,
USB Debugging is on
Bootloader is unlocked
HiSuite is up to date
Correct ADB Drivers are installed
and my device is recognized in both "adb devices" and "fastboot devices"
The problem: I'm trying to flash a TWRP recovery, but I keep getting the error "Failed (remote: Command not allowed)".
I don't know what's wrong, and I don't see any other way how I'd be able to flash a custom recovery. I'm trying to get my phone rooted ASAP.
I also get the same error when I type "fastboot oem device-info" for example, it's so weird I get so frustrated by phones sometimes :silly:
Hope anyone can help me out
Oh and I own a Huawei Honor 7 (PLK-L01 aka plank)
*BUMP*
Anyone who can help me out, please?
