Portrait Keyboard Types gone from 4.3 MJ5
After noticing that the SamsungIME Portrait type keyboards were gone from 4.3 MJ5 I was wondering how I was going to go back to the 4.2.2 keyboard as it was the main one I used. Downgrading to an earlier rom isn't an option because of the new bootloader, so then I was thinking I could simply download the 4.2.2 SamsungIME apk and install it by rooting the phone and copy it into the SYSTEM/APPS folder, change the permissions and reboot after clearing the cache/dalvik cache. All of the versions of SamsungIME I can find either cause the system to crash ("We're sorry but the Samsung keyboard has stopped working" message). My questions, if anybody could help me, are
1) Does anybody have a step by step guide to changing the Samsung keyboard? Is it just a case of putting the apk files in the Apps folder and changing the permissions, clearing cache and rebooting? I've also tried using CWM zip files to load but these fail also.
2) Are Samsung keyboards rom specific i.e. will an MH8 keyboard work in the standard MJ5 rooted rom, or are they also not downgradeable?
3) Would anybody be able to provide me apk and odex file for the 4.2.2 i9505 MH8 Samsung keyboard (if it's useable in the MJ5 rooted rom).
4) This is a long shot, but is there a rooted/custom rom in existence that I can load to my MJ5 S4 that includes the 4.2.2 keyboard and so, still offers the Portrait Keyboard Types?
I would be really grateful for help with this.
