Extract it in some folder.
Download only Patch, drivers and twrp install from here : https://drive.google.com/drive/folde...VUtT3A2UVFtS2M
Than install coolpad assistant from the very first one it has a lot of chines words and its and .exe fail u cant miss, and coolpad setup from the driver folder. After that go to "C: \ Program Files (x86) \ yulong" and install everything that is installable. After that start phone in fastboot mode which is when turn off phone and connect it to pc with usb cable while holding volume and volume down, after that red LED will blink. Or u can go to fastboot trough twrp recovery and find option bootloader confirm it with volume up and there u are. Start coolpad assistant that u installed, browse init.cpb and click check after that and installation will start, w8 it to finish. After that u need to install twrp which u download, start phone again in fastboot, but now using volume up and volume down option cos u dont have twrp anymore( its because JUI needs another one). start MIflash and browse folder TWRP, click refresh and tap on ur phone, its the only option u cant miss click flash. After it is done go to twrp standardly by pressing power button and volume up. Set english language. Go to install folder and Zip file from patch folder. Of course before that u need to transfer it to ur phone.. This patch is important. If u dont install it, it wont boot second time when u reboot phone.
After that download gapps from here : http://opengapps.org/ arm64, 7.1 and aroma check. Go to twrp install and select gapps click flash, Click "Next" - "Customized installation". Uncheck "Load choices". Select "Include" and tick application u want. After clicking finish Click the Home button, go to "wipe" - "advanced wipe", highlight "Dalvik / ART Cache", "Cache", "Data" and wipe. Click "Restart in OS".
After that go to twrp again, and install this chine bloat remover that u firstly transfered to ur phone (this step is not nescessery but I advise u to do it), to delete unnescessery apps. Unrar ROOT file and transfer superuser and apk file to ur phone. Go to twrp again and install superuser. click go to system and install that apk that u transerfed. ROOT STEP IS ONLY FOR THOSE WHO WANT TO ROOT THEIR PHONE. IF U DONT U DONT NEED THIS. I hope that i helpped someone.
Here is my short reviewe. Defenetly uprade eui to this, better interface, less bugs, less heating issues, still some messages dont come, but its around same as eui, even s7 in a very low rate of times have that issue. Battery optimization is much better too.Who didnt upgrade it, do it as soon as possible, cos of lower heating issues which later do damage to your phone and battery of course.
If anyone need help i am here
