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.
Hello,
after having tried to install CWM by using flasify the phone now stucks in a boot loop and I cannot enter the recovery mode. On the other hand I can manage to boot into the fastboot mode but the phone won´t be recognized on the pc i.e. by Minimal ADB and Fastboot: no device. I´ve installed ADB driver but the phone is not shown in the device manager.
I fear I´ve bricked the phone.
Does anybody have an idea how to solve the problem?
Many thanks in advance.
I'm having trouble using ADB with my phone. It is a Galaxy J36, and is stuck in a bootloop. (yes I tried wiping the cache, didn't work ) Every tutorial online is telling me to use adb, so I downloaded the Samsung drivers to my computer. I already have the android sdk. When I plug my phone in to my computer, the command "adb devices" does not recognize my phone. It just shows "list of devices attatched" with nothing under it. I've tried entering odin mode, the system recovery menu, and the boot up screen, but I still get nothing. What do I do? Thanks in advance.
UPDATE: Forget ADB, odin saves the day! https://www.youtube.com/watch?v=BciQSJJsOVc
Hi,
I'm looking for some assistance to unbrick an Allview Viva P8 Pro tablet.
All this mess started from looking after some disk space to install more apps on on the default second partition.
First I've tried some tools like app2sd with no luck and finally decided to try adb/fastboot way, using a linux machine, to root the device.
Before starting the root procedure i was able to boot into recovery mode and while being into recovery mode I could see the tablet as a google device with the proper vendor id 0x18d1. Also "adb devices" command could find the device as expected. Right after issuing "adb restart bootloader", i cannot enter into recovery mode and it hangs with the logo displayed on the screen, i think it's a boot phase before entering into recovery mode.
I can still see it as usb attached device, not with google vendor id but identified as "Onda unverified", with vendor id 0x1f3a. Windows OS finds it as Android Bootloader Interface USB Developer and that's it. I've tried to install some drivers to establish communication but with no luck so far.
Thank you in advance.
Hi !
I am trying to install twrp on my mi pad 4 8", i installed adb drivers but when i turn the tablet into fastboot mode in the device manager it shows the tablet but says it cant find compatible drivers.
I have tryed several drivers but they never work.
When i am not in fastboot mode it opens the tablet perfectly and i am even able to boot to fastboot by using the command adb reboot bootloader.
Thanks for any help,
