Asus zenpad10 tablet stuck in fastboot mode


KEEP HOLDING THE POWER BUTTON UNTIL YOUR PHONES SWITCHES OFF OR PULL OUT THE BATTERY DIRECTLY(If Required) to exit the FAST BOOT MODE and then start your phone normally by pressing only the power button.

Also in case you were trying to enter the recovery mode to wipe cache or hard reset then keep holding the power button and volume DOWN button until you get vibration and release the power button and keep holding the volume DOWN button to enter RECOVERY.

Rca tablet how do i get out of fastboot mode


You will be stuck in fastboot if you have failed to flash an img file. You will have to boot a boot.img file using fastboot then download the last update to get your tablet back to normal.
Download the following file onto your computer...
K1_A301_03_03_110829_US.zip
Then unzip on the computer. You will see a file named "boot.img". Make sure your tablet is connected to the computer and you have the fastboot binary. Then run the following command in the directory you just unzipped the file
fastboot boot boot.img
This will allow you to boot up your tablet but the bootloader will STILL be stuck in fastboot. Therefore you will have to update your system. Download the same file above into the Download directory of your tablet. Rename it to update.zip. Dowload the following XML file...
K1_A301_03_03_110829_US.xml
and rename it to update.xml (NOTE: the system file manager won't let you change the extension so just rename to "update". Power off the tablet. Then hold down the Volume + key and hold down power button until it comes on. That will boot the system into recovery and install the update. In a few minutes you will be restored and your tablet will work normally. NOTE: YOU MAY LOSE YOUR DATA and may have to reinstall your apps.
If your boot partition isn't a mess like mine was, you may be able to just flash the system partition from the above zip file by using...
fastboot flash system system.img
fastboot reboot
The key is that a fastboot flash must be successful in order for your device to boot normally.

I got a lenovo Tablet 3 months ago went to switch it on today and the button is stuck and can't do anything with it


First of all, just try pressing On/Off button gently from center. If it does not help, please press On/Off button gently from each corner once and check if that buttons comes to its normal position and work.
If issue persists, it is recommended to contact your tablet manufacturer Lenovo Support Center to replace the tablet or repair the On/Off button.

What is Fastboot for?

While in fastboot, you can modify the file system images from a computer over a USB connection. Fastboot mode can start on your device even before Android loads, even under the circumstance when Android isn't installed at all. And because of that, fastboot mode is useful for quick-updating the firmware, without having to use a recovery mode. In fact, it's the preferred way to initially install the recovery image. Once you set up, you boot to your phone to fastboot and you can flash image files to the internal memory. Flashing a custom recovery like ClockworkMod is a popular use case. The images you flash don't need to be signed with a particular key, and thus you should use care when flashing. It can also be used for developer operations. Things like erasing partitions and overriding kernel command line options can be done. And all this features make the tool very useful for developing hardware and software solutions, like unlocking the Bootloader of Google' Nexus.
