There are many partition in ZTE open. Normally you only overwrite 4 partition with fastboot: boot, system, userdata and recovery partition. And the phone goes to bootloop etc. And only these 4 partition need to be restored to get things working again. Warning:The default recovery mode update via one zip file is user-friendly and is able to overwrite more that the 4 partition describe above at the same time. So be carefully when you download a non-official 'firmware.zip' file. You may not be able to unbrick it if too many partition is modified/change.
