Try to use 360root, I rooted before so when I update fw still remain rooted, no sure 1.3.8 can or not...
If use kingroot i know how to change the supersu...and also install xposed without custom recovery...for 5.1.1 also can...i will update once i get it rooted...
Xposed can use to block ads from youtube...
For other free iptv with ads can use adaway apk...
Will write a post on all the details with picture to help everyone here and also else where...too many help on the mibox...
Also if theres anything to share please let me know so i can write a huge post on mitv...i already have one on xiaomi forum...but i never update...till now...
Apks or iptv which are stable will help alot...
And google play...im still waiting for someone...only my youtube leanback apk and google play games apk can log in to account...
@pspeter in settings can use the option to install all apks in flashdrive...im using usb 3.0 128gb type so its faster...and the internal will not be full..
@pspeter i can't seem to update...keep going into recovery...is the flashdrive format important?
I used fat32

The stupid thing i did was rename the zip to update.zip
Cause i was trying it on exfat and ntfs and tried to adb sideload update.zip...then after i format my flashdrive to fat32 i didn't rename it back...
Make myself look stupid...
@pspeter sorry bro...hahaha...anyway can update your video in description to add that flashdrive format to fat32...so people won't make my mistake
The unlock ADB my wife found out about it...she press anyhow then get...hahahaha
I think I rooted my Mi TV 2 55 before. But how to check?
Do let me know if can root, if can I found a way to watch China contents from our mitv directly, pretty awesome~but must rooted...
you can changed the DNS of the mitv to bypass china geo block contents without rooting..
tks for your 55" firmware and awesome youtube vids..
