[Nexus 7 Q&A, Help & Troubleshooting] nexus7_usr:
5.1.1 (LMY47V) flash failed

Hi,

I have tried to flash my Nexus 7 2012 from 5.1.0 (LMY47D) to 5.1.1 (LMY47V) using Nexus Root Tool Kit v2.0.5. Everything goes good upto "sending system" command after that I got error Data transfer failed (Too many links).

That factory image downloaded from Google site.

I can't flash it completely. Please suggest me.

Below is the running log (serial number removed)

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, or you

encountered the 'missing system.img' error then enable

'Force Flash Mode' and repeat the 'Flash Stock + Unroot'

processs again. Cheers.
