That Taiwan version is very old firmware. You should download latest Msian firmware. You can use existing ext sdcard n make sure it has 5gb free space. No need to backup but if you need to , you must use CWM . To update firmware you must revert back to stock recovery
You can only use 503l firmware
Try flash back stock recovery
At terminal :
fastboot flash recovery stock_recovery.img
You can get the stock recovery image from XDA
The Mate7 full zip ( for install CWM) has a folder with the stock recovery
Copy this image into same folder where you had the adb/fastboot commands installed
Thanks uncle benny for the guide, i already updated to OTA-7D-501LV100R002C209B_B12.
Thing i have notice is the native keyboard is much more easy to use.
Don't know about battery life.
Contacts/phone/favourite crash 2 times, all white colour screen, need to restart. There is no option to merge/ separate contacts.
The native browser is a turn down, previous version , when zoom in the paragraph will arrange itself to fit the screen, this version cannot, it just enlarge, need to scroll to the left to read whole sentences( any solution?).
I cannot import the google bookmarks into this browser( something wrong?)
