Yes,yes it is. Flash that and root it! and when your ready take the plunge and update to 4.0.4,Since your unlocked! Restore your /EFS if it does get lost
if it locks networks (and i mean if,which again is rare) I know a simple guide you can follow to get 'er back unlocked
EDIT: okay, I read the beginning of the thread. I see where your coming from. Now I understand why you want Root!
Do you need help trying to root it or do you understand that much?
Thanks! (I don't know how to express how much I appreciate your help...)
I think I have "somehow" clear the steps to follow, including initial rooting.. On big steps:
1.- Backup Apps (probably will use Kies)
2.- From the file trwp2.6.1.odin.zip, I'll install Odin on my PC and obtain the recovery.tar.md5 file (TWRP recovery).
3.- Will Flash this .md5 file with Odin on my mobile (need to watch your videos to ensure the Odin options to use, but mainly I think I need to
3.1.- enteri the phone in Download Mode (holding Volume Up key (keep holding it until options screen are shown) and then pressing power key once). On the next screen, pressing Volume Up once to boot into download mode).
3.2.- From Odin, use PDA option to select this file, ans select auto reboot" and "F: Reset" opetions .. leave the rest of hte options blank.
At this point, I'll already have the TWRP recovery on my mobile.
3.- Time to root the phone:From the SGH-I927RUXKJ5_STOCK_ROOTED.tar.bz2 file (290.298.391 bytes) extract SGH-I927RUXKJ5_STOCK_ROOTED.tar (rooted 2.3.5 Rogers ROM), and flash it with Odin (will follow same steps and Odin Options as to flash the recovery file).
At this time, I'll have my mobile rooted.
4.- Backup EFS: I'll execute the tar commands commented in the thread, as well as will use the EFS_Professional_2.1.73 SW
At this time, I can break my mobile (hopefully not) as I'll have every ready to recover. :angel:
5 .- Flash with Odin (again, same steps & options as previous flash performed) the file I927UCLJ3_I927ATTLJ3_ATT (AT&T firmware fom 2012 October). I've see you have many ROMs in your page... I do really need to watch your videos before starting this step... which ROM would you recommend?
6.- If after rebooting the phone I can't enter the phone due to SIM code or mobile does not register in the network, restore the EFS (I might need to unlock the phone again by entering the Network lock control key if requested) (already have it ready)
At this point I'll have the phone updated to the latest version, and rooted (well, not sure if rooted... if not rooted, I'd need to root it again in order to restore the EFS, if needed... so, in that case, back to start..
How do you see these steps? (this week-end can be a great week-end for my mobile...) (hopefully!)
Thanks!
