please change your recovery to twrp 2.6.3.3 as mentioned below:
A) Having Problems? Rule #1: check MD5 on all your downloads; one single corrupt download can keep you trying for hours on end for nothing!
https://www.google.com/#q=MD5 ; Basically (in our context), MD5 checksums are to verify that the file you downloaded isn't corrupt
on Mac, Linux, and Android terminals it's already built in:
Mac: in terminal, just type md5 <name of file>
----> MD5 (<name of file>) = 12345678901234567890123456789012
Linux: in terminal, just type md5sum <name of file>
----> 12345678901234567890123456789012 <name of file>
Android: in "adb shell", just type md5sum <name of file>
----> 12345678901234567890123456789012 <name of file>
Windows (seems not built-in!?!?): you can use programs such as http://winmd5.com/ , http://implbits.com/hashtab.aspx , http://www.pc-tools.net/win32/md5sums/ or any other one of your choosing.
C) Problems installing a ROM (in particular 4.4+ versions, and getting permission/set_metadata errors)
for M7_U/UL models, get TWRP from:
2.6.3.3: http://techerrata.com/browse/twrp2/m7
or 2.6.3.4: http://techerrata.com/browse/twrp2/m7ul
(make sure MD5 is correct, that site does not play nice with download managers)
Note: at the time of this writing these are the most reliable versions, even the 2.7.x.x series seem to still have problems
in bootloader/FASTBOOT USB:
fastboot flash recovery openrecovery-twrp-2.6.3.3-m7.img
fastboot erase cache
fastboot reboot-bootloader
-> enter RECOVERY and install the ROM

ADB doesn't work so I can't use fastboot. It is not showing up.
