Please let me know if it works for you!

Currently I'm almost done with the custom rom MIUI.
I am planning to release it next week. I want to know if the recovery works fine for everyone
so I can release it next week and everybody can install it without any problems.
So it's important if you installed it to let me know it worked.
Step 1. download the recovery.img below
Step 2. install mobile uncle tools from the playstore.
Step 3. Make sure you've rooted your ISA A19Q. Not? Check my root tutorial!
Step 4. Connect your sd card to your pc and drag the recovery.img to the root of the sd (so not in any folder).
Step 5. Open mobile uncle tools and select Recovery Update.
Step 6. You should see the recovery you placed in your SD card. Select it and click on OK. Finally, choose reboot to Recovery. If all was done correctly, your phone should boot into your new cwm recovery.
GOOD LUCK. If something strange happens (very unlikely just reinstall the rom. Check my root tutorial for the rom)
