A. Yes... coz DEV is for testing & ST is for stable version...
I dun wan to test coz dun have an extra hp for testing... So I prefer stable version...
B. No idea coz yet to try
C. Yes
D. No coz ur recovery still custom.
I think people are confusing on OTA / ROOT / GAPPS
For stock rom (DEV & ST)
- if u want OTA, u will not be able to install GAPPS & ROOT.
Why ? Bcoz stock ROM doesn't coming with GAPPS & ROOT. So to have it, u need to install via recovery.
But ? U're unable to install GAPSS & ROOT via stock recovery coz stock recovery didn't recognize the zip format
So ? To solve this, u need to flash custom recovery (cwm/twrp) via flashtool
Then ? Once cwm/twrp installed, then u can install GAPPS & ROOTS
OTA ? OTA can be dloaded into the hp but when u wanna install, it'll detect that u don't have stock recovery. Hence, failed to install.
Solution ? If u wanna latest ST rom, u need to dload the whole rom (8++mb) and flash via cwm/twrp. Then flash GAPPS & ROOT again. Once ur hp booted, u need to restore all ur app via Titanium Backup.
Thanks sitescope for the clarification. Understanded liao
BTW, can we install GAPPS and ROM even without the use of the SDCard as mentioned in your guide?
