Nexus 4 updata4.4 疑問

我用 Nexus toolkit 1.7.6 想刷原廠 Android 4.4
可是現在卡在一個點就是:
他會說找不到某幾個檔案，我去 XDA 爬文也有人有這問題，他們是說重新安裝 adb and fastboot 就可以了，所以我就重裝 Nexus toolkit 1.7.6 就可以了吧 ?可是我還是不行 ...
日誌檔內容為下，希望有人可以救救我 ..

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.
