Why you thinking that you did something wrong with instalation. Is something wrong with your device after installation.
You can go to settings - backup and reset - factory data reset and system should be completely clean.
If your phone not responding you need use SPFT and flash whole ROM using only firmware upgrade. But if you brick your phone you need use format all + download. Here is link for latest ROM Android 7.0, SPFT and driver http://community.umidigi.com/thread-5751-1-1.html
And here is basic instruction for using SPFT http://community.umidigi.com/thread-11-1-1.html
After this process you probably loose your IMEI no and you need use SN writer tool to restore your IMEI no. Here is link for SN writer tool http://community.umidigi.com/thread-1375-1-1.html
I deleted your other thread as that was nearly the same question.
Preloader and other partitions needs to be checked when you changing Firmware from one to other version.
Preloader is contents usb driver for preloader mode , partition table and low level boot command.
If you uncheck preloader some partitions could be not overwrite and there could be complications between new firmware and some partitions.

Please go to settings - about phone - status - IMEI informations.
If you have no IMEI numbers (incorrect only one's or two's) please use link from last post and restore IMEI numbers with SN writing tool
Please send me link with information about preloader unchecked for umi plus.
Only we suggested uncheck preloader for umi max and super as at some time of production there was two screens types available and ROM wasn't including correct tp driver.
Hi
This is basic information for all types of phones. As we have full ROM file available you no need to be worry about preloader especially on umi plus device as in this ROM is everything fine.
We always recommending check all boxes as then you getting full upgrade.
All partitions are compatible and you will not get any complications between systems.
If you uncheck preloader some partitions will be not overwrite and new drivers (if are available) will be not added.
