[Xoom General] HinotoriBR:
Whoever has MZ608 RETAIL (retail is not Vivo, Tim, Claro, retail, like, the version uploaded in droid-developers: http://sbf.droid-developers.org/xoom2/list.php, 1.6.0M-272.12_MZ608_p2HW_BlurRegion02_CFC1FF_fastboot_signed_latam.xml.zip), a friend from a Google Groups list has received the OTA and after I bugged him to get the OTA file (as he was not able to apply the update initially, it was failing), he uploaded it to Google Drive:

https://docs.google.com/folder/d/0B1j_akDAebUUNk4wSTNwcXlTTkU/edit

So, compliments to Sergio Gamero for sharing the OTA for MZ608 retail.

Also, while we tried to find out why his update was failing, it was due to the MD5 of one of the APKs (in his case, accuweather widget) not matching. It seems that somehow, RSD Lite failed to flash it properly or the SBF file he use to flash his MZ608 was corrupted only in this specific file. Some people that got the error to apply the OTA update reported that downloading the SBF from droid-developers and flashing it again and then doing the OTA worked fine, I was lucky that I did not need to do this, I've just entered recovery and everything worked fine and kept my files/settings/etc...

What to do with the OTA files (put all of them in the same folder):

- Copy both files to the root of internal SDCARD/Memory and external SDCARD (probably one of them is not needed, but as Xoom 2 is slow like hell to reboot, I did not want to figure out which one is not needed)

- Turn it off

- Keep pressed both vol+ and vol-, and with both pressed, press and keep pressed power as well untill a screen looking like a personal computer from the 80's appear

- Choose recovery (vol- navigates through options, vol+ choose the highlighted option)

- When the android picture apears, press vol- and vol+, use vol- to navigate and highlight Update from sdcard (or something like that), then choose it (to choose the highlighted option in recovery, press power)

- I've choosen the zip file like explained before (vol- and pwr), it took a while to finish (remember to have plenty of battery juice before trying to do this), when it finished, I've choosen the reboot option and presto...

If it fails to apply the update and you're sure that you have Brazil Retail ROM, you could try to apply the SBF from droid-developer using RSDLITE (if you already have the SBF file, download it again, as the file itself might be corrupt), it has worked for a lot of people (but if I'm not mistaken, this will wipe your device, so, have a Titanium backup prepared).

Notice that doing an OTA update kills your root, be smart, use Vodoo OTA Root Keeper before doing the OTA, save your root, after everything is done, use Vodoo again to restore root, it is easy and work like a charm.

If you need further instructions, I am sorry, but I'm not confortable giving them, it is already detailed, step by step, if you don't understand it, just wait the official OTA notification appear to you, it should appear soon, as the update work fine and soon Motorola will release it for every device.

Usual "I'm not responsible if hell freezes over or kittens get killed in the proccess" disclaimer apply. This has worked for me and a few friend, but I have no way to guarantee it will work for everyone.
