***This is what we know so far***
Version/Builds so far:- MI1 (4.3) ⇔ MI9 (4.3) ⇒ MJ5 (4.3) ⇔ MLG (4.4.2) ⇒ Future (4.4.2, OTA)
To downgrade back to MJ5..and still have Knox 0x0.
Follow this guide
No ART support on Official or Leaked TW 4.4.2
Unofficial S-View covers don't work anymore. (Workaround for it here
.. But it requires ROOT & Xposed Framework
Google Wallet still doesn't do Tap and Pay and host card emulation seems to be disabled entirely.
If you Sim-Unlocked before (on MJ5, MI9 or MI1) using RegionAway... You will still be Sim-Unlocked after flashing this 4.4.2.
Here are the APN settings that you might have to add in manually after flashing this (For people who can get Mobile data to work). Look here.
From reading International N3 thread about 4.4.2.....Leaving out 4.4.2 BL causes bootloop...and the only way to get around that is by flashing 4.4.2 BL
Flashing through OneClickBin.exe doesn't trip any flags...but it does upgrade your BL.
Flashing 4.4.2 via OneClickBin.exe or via Odin *both* method will completely wipe off your phone. (So make backup first).
Exploit that Safestrap Recovery used
doesn't work on 4.4.2 anymore. @Hashcode
would have to update the SS.
Currently No Root for 4.4.2 (Universal RDLV and Kingoroot don't work).
Possible but requires jumping through few hoops. Look here for details
Once you upgrade BL to 4.4.2,
you wont be able to downgrade back to 4.3
. (You should be able to roll back to MJ5 but not to MI9. (Look above for "Version/Builds so far" for more details)
Why does #9 matter? Well because ..let's say someone in future discovers an exploit in 4.3 bootloader (MI9) that allows us to flash custom kernel/recoveries...people who upgrade now wont be able to downgrade back to 4.3 and they won't be able to use that exploit.
But let's say someone in future discovers an exploit for 4.4.2 BL then people who decide to stay on MI9 right now will still be able to use that exploit since we can upgrade but not downgrade.
So people who decide to upgrade right now are really taking a chance. And also keep in mind that with each update Knox/BL security gets more and more refined/harder to exploit.
are currently working on getting MI9 BL unlocked or find an exploit that allows us to flash custom recoveries/kernels.. And @ryanbg
has made some pretty good progress so far.
And finally don't forget to Thank @designgears
for this awesome leak.
