Although I said in my previous post that this mod was working for me, my SM-T800 was unstable.
So, I decompiled android.policy.jar from my rom, and recompiled with your GlobalActions$99$1.smali, GlobalActions$99$2.smali, GlobalActions$99.smali and GlobalActions$SinglePressAction.smali.
(I edited GlobalActions.smali by changing $8 to $99 in two positions, too)
Now, the device is very stable, and it boots into Recovery without any problem, but when I choose Download/Odin, it does not go into Download mode but it just reboots, as before.
I have a Note 2 with 4.4.2 with extended reboot menu, which does reboot into download mode. As I thought the secret is in GlobalActions$99.smali, I compared the files from the two devices, but I don't understand much.
Can you help me to solve the issue? I am attaching my android.policy.jar and public.xml from framework-res.apk (If I understand well, public..xml is useful to check ids...)
The attached android.policy.jar is from and works with T800XXU1ANH1_T800OXA1ANH1_XEF( (rooted, deodexed and deknoxed with Archi Kitchen. Thank you), but rebooting into download//Odin does not work.
I would really appreciate any help.
