Upgrade android L and nexus7android in the second generation of nexus7

After a long time, I found it was actually very simple...

1. Install the gdb and bootloader drivers in windows. Enable usb debug and press the power key and volume reduction key to start the bootloader. As for unlocking this, I will say more.

2. Download the android L image (the nexus5 and nexus7 are different. Be sure to separate the download. Otherwise, the flash bootloader signature is inconsistent)

3. When running flash-all, be sure to enter the relevant directory, otherwise there will be printing such as no error,

4. By the way, the fastboot and gdb gadgets are really easy to use. You can simply click on them in the command line.

Will the next generation of nexus7 be upgraded to Android 44?

All of Google's N series products will be pushed first. If it is 4.4, it is estimated that it will not be ready until the end of the year! However, I usually don't wait for the push, just wait for them to refresh and check the situation again!
 
I bought nexus7 generation II update android43 yesterday. One cannot be updated.

Updating the system will not erase your device data. You have never seen this happen before.
The simplest method is: 1. Restore the factory settings and connect to wifi at startup. The system is automatically updated.
If the value is always stopped at 524, it indicates a network problem. You can download the value after you connect to the vpn.
