[RAZR i General] jacbarahona72:
EDIT: I have a unlocked bootloader it's no neccesary for update only for install recovery

Share only how update, using a file KitKat OTA

0 .- Backup your Data (nandroid, copy the internal sd, messages, etc) i use ROM TOOLBOX

UPDATE ONLY

1 .- Install the firmware with rsd lite retail brasil (the more latest JB 4.1.2, Blur_Version.982.50.29.XT890.Brasil.en.BR, WHICH CAN DOWNLOAD HERE http://sbf.droid-developers.org/phone.php?device=13 do not forget to delete the line

<step operation="getvar" var="max-download-size" />

Note: reboot first, and configured, if you choose

2 .- Go and download that file ota to share in communities of google+, unchanged, from my driving in Mega https://mega.co.nz/#!IA0mEbAA!btE6lSxMwOpT1YXbg7W3VoMXAEBfhIOiIJfzjc5aEck

I, in this case rename as update.zip (to shorten the name), i placed in the External SD

3 .- Access recovery (and which will be of stock) update from External SD and search the file have rename update.zip, but will start flashing because there will be a reboot that first update the recovery (relaxed, nothing happens), back to the point of android tummy with up and again have to access the recovery by pressing the button repeatedly volume up and down at the same time, search again update via the sd external and get back to flash the same update.zip, but in this case, not stop until end (takes a little patience).

4 .- Restart your phone and ready

OPTIONAL FOR ROOT (UNLOCKED BOOTLOADER IS NECCESARY)

5 .- May not be surprise, but i just write this post to finish the process, which i explain . . . . . and now i will try to rooting across any way, but first install recovery "TWRP 2.8.0.1". From here http://xdaforums.com/showpost.php?p=55417096&postcount=2 thanks for repack to [MENTION=4507138]KREAT0R[/MENTION]

BACK IN ONE MOMENT..

5.1 .- TWRP 2.8.0.1 install without problems (with the Razr I in fastboot Mode via pc type in cmd window .... fastboot flash recovery *the name has its recovery*.img or install easy, see here http://xdaforums.com/showthread.php?t=2166646)

5.2 .- RazriRoot2.zip install without problems (WITH ZIP FOR ROOT OF JB) See here http://xdaforums.com/showpost.php?p=54497016&postcount=1 THANKS FOR RECOPILATION [MENTION=4479363]Hazou[/MENTION], was not necessary

5.3 .- Install The Last Supersu Zip thanks to[MENTION=631273]Chainfire[/MENTION], Via recovery immediately after RazriRoot2.zip.

OPTIONAL IF YOU CHOOSE

5.4 .- BusyBox FREE the latest version install (if you want)

6 .- Restoring my applications via Rom Toolbox

7 .- Reboot in ART (I imagine if you could tell DALVIK performance, in ART should be much more obvious and of a soft way more) no ... DALVIK is better in this case

LUCK: ok:

Perceived performance with benchmark from the rom toolbox i can measure in a 10% to to 15% better than jb (is much faster). . . . .battery test(12-16 Hours per charge, use to full)

NOTE 1: There is a small, "error" when accessing the recovery, indicated "failure" ulogo briefly in bootloader screen, must be that now there are two images to restart the phone will, the logo of motorola and then the poster warning for those who have the Bootloader Unlocked.

NOTE 2: First . . . . If you had Xposed Installed, and select Runtime "ART", Not Running Never, Reboot ever in Dalvik Runtime

Second if you Had ART runtime and after Install Xposed

Xposed Installation, changes automatically to DALVIK in the reboot (rare but happened to me)

NOTE 3:With Xposed Active

Modules

Gravitybox ok

Unicon ok

Greenify ok

HKthemer (Not working properly) some themes worked

Dalvik Runtime is Better than ART in this case, I mentioned up
