I really need to understand how the bootloader or recovery does ROM installs.
It looks like the process is very different from what I'm used to with my
tablets and phones.
Normally I 'fastboot flash recovery recovery.img' from the bootloader
to store a custom recovery, (CWM or TWRP).
use the bootloader to reboot to recovery.
If the rom a factory reset zip the bootloader
looks for a 'magic file name' to install.
if its a normal rom, replacing only boot, system, data and cache
then its done with recovery.
put the rom's zip file on an sdcard formatted fat32.
use recovery to 'wipe' system, data and cache
partitions.
then 'install' the rom's zip file from recovery.
rebooting to system starts initial customization
and device setup.
Here it looks like I create a fat32 sdcard with the
rom zip file, a recovery.img and a housekeeping
file that directs the bootloader to install
system and wipe the data and cache
partitions?
Without a custom recovery, how do I
install the after files, or do I need to?
The rom zip file seems to have a directory with the patches
already there? are the after ones later updates ?
I'd planned on running a restore of my
apps and data from recovery (using the
recovery mode zip that Titanium Backup
creates).
I wondered if I just put the database
on the sdcard and install the 2 apk's
for titanium backup from play store
and point TiBu at that databases
and restore missing apps and their data?
Is the Rom configured to tell Play Store
its a Nexus or is there a separate patch for that?
Thanks
A confused X8-H noobie
