我的N7-2013幾天前剛OTA刷5.0.1, 沒有root, 沒有解鎖.
前天晚上充電時自動重啟, 但一直停留在GOOGLE界面.

嘗試跟https://developers.google.com/android/nexus/images刷官方5.0.1 rom
我的N7-2013 還可以進bootloader mode, 去到了UNLOCK (fastboot oem unlock), 一直卡在erasing userdata. 一個小時都沒反應. 爬文說因為沒有開USB DEBUG, 所以不能UNLOCK.

找舊POST 看到這個:-
http://www.mobile01.com/topicdetail.php?f=565&t=3552595

嘗試用Nexus Root Toolkit > Flash Stock + Unroot 重刷官方5.0.1, 但失敗. 是否因為未UNLOCK?

現在開不了機 > 沒有辦法開USB DEBUG > 無法unlock > 無法刷rom

現在可以怎麼做??

先unlock, 再erase all , 若Device只能開到fastboot, 就選Nexus Root Toolkit > Flash Stock + Unroot, 然後選soft-bricked/bootloop這個

若成功後, 記得再lock, 就能開機了.

試看看吧

run完之後，N7沒有改變任何東西。
我重啟到bootloader, lock state仍然是locked

方法二樓有說了，
如果還是一樣的話試著刷別的版本看看，
因為我前天也是這樣。

已經試了好幾個版本了 4.4.4, 5.0.0 及 5.0.1
都是一樣, N7都是沒有醒過來, 有點想放棄醫治~
下面是flash stock 的log

Booting up your freshly flashed stock device...
------------------------------------------------------------------

Wait for your device to finish booting up...

- It may appear to be boot looping; just wait...

- It could take 5-10 minutes; please be patient...

When its finally booted back up, please remember
to re-enable USB debugging if you plan on using
the toolkit to perform other operations.

NOTE: If this process was too quick and your device
is still in bootloader mode, then flashing stock may
have failed or been incomplete. Simply check the
log above: if you notice it skipped steps because it
didn't meet certain requirements, like the bootloader
or baseband version, then consider enabling 'Force Flash'
mode in the toolkits options menu and trying the
'Flash Stock + Unroot' processs again. Cheers.

Press any key to exit...

Unlock 只需一次，但是那是資料會全消失，以後就不用管他了.....
因為你要刷 Firmware & Root 前都要先 Unlock
