if you have lenovo yoga2 1050L please send this backup of your important factory partitions to me:o
with this method (IntelAndroid-FBRL-07-24-2015)in xda forum http://ift.tt/1FT18Nt
you can backup from important section of tablet that i think!
in "IntelAndroid-FBRL-07-24-2015" after you type ACCEPT to begin then select "1"(twrp_hdpi_landscape.zip)then if on kitkat select "T3" and when install is complet go to recovery>>>swipe to allow modification>>backup>>and you see "select partitions to backup" just select this partitions: ESP-BOOT-RECOVERY-FASTBOOT-FACTORY-CONFIG and another again back up of ESP-FACTORY-CONFIG
please send backup files to my email for my try and test.
