I have a Orange Intel Inside aka Orange San Diego from the French provider Orange.
Currently, it's running the original stock firmware:
Android version: 2.3.7
Version IFWI: 05.52
BaseBand version: SUNRISE_SMB_REV30_V2_B1202_1208.K
Kernel version; 18.104.22.168+ svnadmin@nataku09 #1
Build number: AZ210B_GB.01.04
The phone is unlocked but not rooted.
There is an OTA update available, which I haven't done yet, of 261 MB.
I don't know what it does exactly (ICS maybe?)
Here is my question:
I'd like to upgrade the firmware to some version (unknown yet, this is the purpose of my question) which would allow me to:
1) root the phone, so I can install the Xposed framework which I use on another phone
2) enable the USB OTG
3) maybe (not mandatory) enable the internal micro-SIM slot for further use.
As I'm going to give this phone to my parents, who know nothing about Android, the upgrade has to be safe (i.e. when a new upgrade will be available via OTA, it must not brick the phone or do anything bad)
From reading the forum, I understand that people installed via USB the X900 (ICS?) update, which allowed rooting but with which some problems occured (wifi, 3G...), then people went back to "Orange ICS" but I'm not sure why and whether it could be rooted for Xposed.
So... as you can see, I'm a bit confused, and I'd like some knowledgable persons to help me in choosing the good decision/firmware, and direct me to the relevant URLs for tutorials.
Hope this is not asking too much!
