[APP MOD] Exchange Security Bypass (No PIN) - Android 4.2.x/4.1.x
This zip contains the patched Android email/exchange client which disabled/bypasses the Exchange security requirement, allowing you to set up Exchange accounts without the lockscreen password or PIN requirement. This was built from the Android 4.2.1_r1 source. It will work with any device running Google stock or AOSP-based ROMs (including CM10.1, AOKP, ParanoidAndroid, Evervolv) built from the Android 4.2 source (4.2, 4.2.1_r1, 4.2.1_r1.1, 4.2.1_r1.2 & 4.2.2_r1.1). This may not work on all custom ROMs and may not work with all manufacturer/OEM ROMs (Sense, Touchwiz or Blur).
v2.0 of this mod is built using the CyanogenMod 10.1 (Android 4.2.2) source and has some nice additions and fixes over the AOSP version like LED notification support, blocked attachment extensions selection and some more.
This will ask you to set up your account as a "Device Administrator", but it will not ask you to enter a lock screen pin or password.
1) Download the attached zip file
2) Remove all existing Exchange accounts
3) Make a nandroid backup (Optional)
4) Flash using CWM, TWRP or a similar custom recovery
5) Wipe cache/dalvik-cache
6) Re-setup you Exchange account(s)
You need to have a device with an unlocked bootloader and a custom recovery.
Root is not required unless you wish to apply this patch manually by replacing the files in /system/app.
After you flash this, make sure you don't replace the Email or Exchange apks with themed versions or you will have issues. Also, you need to reflash this every time you update your ROM.
1) This zip contains modified system files. Please use this at your own risk. It is recommended that you create a nandroid backup before flashing this.
2) This bypasses the Exchange security requirement which may not be legal or may be against policies at your workplace or school. Once again, use at your own risk.
3) You may lose additional features, if any, which your custom ROM has added to the Email/Exchange apps which are not part of AOSP.
I don't remember who figured out the necessary changes. I have merely reproduced what I have found trudging through the extensive information made available here and on Rootz. Credits to whoever actually found these mods.
