Hey friends,
I attempted to flash a new ROM, but obviously things went wrong.
Here's what is happening now.
- I cannot turn on the tablet with any key combination - only by plugging into the wall and waiting a while - eventually it powers on
- Once powered on it remains with the Acer logo and lists the bootloader at the top (ICS), no fastboot at this stage, but do have ADB
- Can get to fastboot by "adb reboot-bootloader"
- Once in fastboot, have flashed new recovery, and rebooted
- When rebooting - no menu is presented for getting into recovery, and key combinations won't get me to recovery either.
- I then tried flashing a new boot.img - now adb says
error: device unauthorized.
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.
Any ideas on what I could try next? Thanks for any help you can give...

Still trying to decipher a bit of the lingo/tools but...
I did an "adb reboot bootloader" and it just hangs at the "G'zone" bootup screen.
And an "adb reboot recovery" gives me the exclamation point with the android.
Where do I go about getting/enabling the bootloader or recovery console?
(Also did several variations on the power up and pushing volume down, picture button etc with no change in the default boot behavior.)
Fastboot Disabled
Looks like the source of my troubles is due to fastboot being disabled.
Doing "adb reboot fastboot" just causes it to reboot normally.
Attempting to find a way to enable fastboot mode.
Hey All,
My Dad's Xoom died over the weekend - 13months after purchase so is not covered by the warranty. He was browsing a site, it came up with a "Internet is not responding - do you want to continue to wait" message and he clicked Wait - after a second the tablet knocked off. It will not come on by pressing Power and only turns on by pressing Power and Vol +
It gets past the Motorolo logo screen and the device starts the boot animation, about 20 seconds into this it freezes and reboots - this continues in a loop. It's been GEDified and was running the last OTA update 4.1.2 - no root etc.
I can get into the stock recovery and performed a factory reset - but the same thing happens. I've also tried Update From USB with an OTG cable but the screen just shows Choose a package to install and under it has /sdcard but nothing else. I have a dummy zip on both the Flash disk and SD card so it's not reading either.
I've also tried to perform update via ADB - when I select it and connect to a PC (Win 7 32bit) it tries to install drivers but I see In Computer Management that it shows under Unknown. ADB Devices returns List of devices message but nothing under it.
I've also selected the fastboot command at boot, tried fastboot devices and the command does see the Xoom.
So my questions
1) Anyone seen anything like this issue before and know how to fix it?
2) Is it best to try to reinstall the ROM? If so, how do you suggest I can see it with ADB?
3) As I have Fastboot command, could I try to install CWM and see if that sees a ZIP on the sdcard - so I can install a new ROM.
Any help much appreciated :good:
so...I've just done a fastboot oem unlock
and then tried to flash the CWM recovery using the fastboot commands - no errors, press reboot and go into Recovery but still getting Android system recovery 3e :crying:

So just to add to this, I found the stock recovery.img, boot.img, userdata.img and system.img and used the fastboot commands to send all to the motorola - all succeeded without error....still the same problem though.
I installed RSD lite and tried a few SBF files but I'm getting an INI error - off to google possible solutions to that now
I just got this phone, and was told to unlock the bootloader and flash custom recovery as the first step, so I'm following this guide: forums.oneplus.net/threads/full-guide-setting-drivers-up-unlocking-bootloader-flashing-recovery-roms-kernels-rooting.291274/
I've been following it to a T and everything was working well. Once I got up to #3 and type in cmd "fastboot reboot" and it boots back to normal mode (so I can disable Cyanogen Recovery), typing "adb reboot bootloader" in cmd returns "error: device not found." If I'm in fastboot mode and enter "fastboot oem device-info" it returns true for tampered and unlocked so I know I have the bootloader unlocked. If I'm in normal mode, the phone shows up in device manager under portable devices. If I uninstall it, it disappears from the list. Once I unplug it and plug it back in, it pops back up in the same place, saying device installed correctly. If I try to update the drivers, most of the options from the Manufacturer list (see in the gifs from the guide) are gone, including the google ones.
How do I move from here? should I just wipe the whole thing and try again? What's the best way to do that? If I use the the USBDeview thing and remove the A0001 driver, will that allow me to put the android ADB Interface on the phone (Basically starting over)?
Thanks friends. Really excited to get going on Android!

You probably don't have ADB enabled on your OPO, but you don't even need it for this. "adb reboot bootloader" is just a handy way of rebooting to fastboot without shutting down and holding the up volume button while turning it on. Once you get into fastboot by doing that, continue on as the guide says! (i.e. "fastboot flash recovery xxxx.img")
Hi,
i'm facing the problem that my phone only starts in "FastBoot Mode" at least i guess that's the mode.
OnePlus 6 with root.
It happened after i rebooted after installing an OTA Update and installing a Magisk Manager Update.
I used the method described here. The last few times it worked perfectly.
But now the only thing that happens when i try to boot the phone is a screen that says
FastBoot Mode
PRODUCT_NAME - sdm845
VARIANT - SDM UFS
BOOTLOADER VERSION -
BASEBAND VERSION -
SERIAL NUMBER - d8a34971
SECURE BOOT - yes
DEVICE STATE - unlocked
with the volume button i can select "START, Restart bootloader, Recovery Mode and Power off"
but nothing happens when i select e.g. Recovery Mode, or simply START.
The phone shows the boot logo for a second, then I'm back at the screen with "FastBoot Mode"
I installed the USB-drivers for the device and can find it with my PC when i type "fastboot devices" in the command prompt.
But that's pretty much all. I don't know how to continue.
I would be very glad if i could keep my data, is there a way to save my phone and if not how do i install the normal OS again?
I really hope someone can help me here.
Edit:
When I type "adb devices" it says "List of devices attached" but there is no entry.
USB-Debugging is on, since the Root-process i didn't touch the developer options
So should be the USB mode for file transfer (MTP)
I'm not sure if i checked the "always allow from this computer" setting
So following this guide the only thing i can't do is checking the prompt for USB-debugging since i can't boot the OS.
Is there anoter way to get a adb connection?
[ROM][STOCK][FASTBOOT][OP6] Stock Fastboot ROMs for OnePlus 6
Things are changing with the advent of project treble and seamless updates. OnePlus will no longer release ROMs flashable via stock recovery (with twrp is possible but not recommended). The updates will be done on the slot not used for example...
forum.xda-developers.com
For everyone that can't connect to the device via ADB but fastboot, this does the trick.
Thank you guys!
Hello everybody,
I have a LG K520EMW with Android 10 Stock ROM,
According to Treble Check I have a system supporting system-as-root and a system partition A/B
So I downloaded a GSI from the phhusson's Treble Experimentations
But here are my problems :
- the phone won't boot at all on Fastboot mode (tried adb reboot bootloader, adb reboot-bootloader, both from sideload mode and normal mode, tried plugging the phone when it's off holding vol + or Vol - keys, and using QuickBoot, obviously didn't help because the phone is not rooted)
- the phone won't boot either on Recovery mode, it displays "No Command", i've tried all possible key combinations with vol +, vol -, power, camera, nothing happens and it stays on "No Command",
- Can't root with any tool, I tried KingRoot, KingoRoot, mtk-su
The only door open for me right now is sideload, I know I can type "adb sideload rom.zip" but the issue is I haven't unlocked bootloader, so I don't know what happens if I do this...
I've found nothing on the web about this phone, so if anyone have some informations or knows any procedure on another phone which would be applicable on this model, it would be great
Well, some news, i've figured out a dirty vay to access Fastboot mode, very very dirty :
I've tried, just to see what it does, adb sideload lineageOS-18.1-etc.img, and like a rabbit getting out of a hat, a recovery menu appeared and I could access Fastboot,
Now, I still have to find out why when I try fastboot oem unlock or fastboot oem device-id ( LG official procedure )
I have enabled OEM unlock in debugging options of course
On the Fastboot screen, Bootloader version is unknown,
When I try fastboot boot twrp.img, it answers "Download is not allowed on locked devices"
So, if anyone has an idea, I'd be very grateful
