Hi,

I have a Nexus 7 (2013) which shipped with Lollipop 5.1. I tried to build the image from aosp source codes. I downloaded the source 4.3_r2.2, and built the image. I also included the device binaries before the building. All of steps just followed the Google's instruction. But after flash and reboot, it just stuck on the Google's logo screen. The binaries I'm using is Nexus 7 (Wi-Fi) binaries for Android 4.3 (JSS15Q)

I also downloaded the 4.3 factory image from https://developers.google.com/android/nexus/images and flashed it on the device. But still have the same problem. Can anybody give me some hint?

Thanks.

Just for further testing, I downloaded another several different factory images after that, which are 4.4, 4.4.4, 5.0 and 5.1. Finally, I found all images below 5.0 can't work on my device.

The steps I flash the image just following these steps:
1. Reboot the device into recovery mode, wipe the user data and cache;
2. Reboot to the bootloader, unlock the device by "fastboot oem unlock";
3. then running "flash-all.sh".
All of these were successful. But after reboot, it just stuck on the Google's logo screen.

I also noticed there're some error messages if I go to the recovery mode like these:

E: failed to mount /cache (No such file or directory)
E: Can't mount /cache/recovery/log
E: Can't open /cache/recovery/log
E: failed to mount /cache (No such file or directory)
E: Can't mount /cache/recovery/last_log
E: Can't open /cache/recovery/last_log
E: failed to mount /cache (No such file or directory)
E: Can't mount /cache/recovery/last_install

E: failed to mount /cache (No such file or directory)
E: failed to mount /cache (No such file or directory)


I searched quite a lot on the internet, but didn't find the solution so far. I also tried with "fastboot format cache" and "fastboot erase cache", but doesn't work for me.
