You need to make ICS recovery.img manually.

Extract recovery.img.p from OTA zip. Patch it to the 2.3.6 recovery.img

Flash it to your phone & apply OTA.
[Motorola Droid RAZR] evonc:
For the people that are planning to restore to 2.3.6 RetailBR from Chinese ICS .120, I have a good warning for you.

When you are restoring, DO NOT restore your mcmblk1p18 until you have flashed GB or else you will have issues flashing 2.3.6 on to your phone.

If you are already stuck, You need to manually flash every single part of the 2.3.6 fastboot using the adb and moto-fastboot. The commands are in the xml file in the fastboot that is decompressed.

For example to flash system it would be:

moto-fastboot flash system system_signed

You do realize that if your device is bought/sold in Europe, then this official update is not for you, right?
[Motorola Droid RAZR] Ronis_BR:
Just to inform that the update to ICS was done flawlessly!

I have a Vivo RAZR that was updated to Gingerbread 2.3.6.

I followed all the instructions in the OP, but I wiped everything before applying the update. Everything went fine.

Thanks one more time, this is just amazing!
[Motorola Droid RAZR] stangri:
Have you tried steps in this post: http://xdaforums.com/showpost.php?p=27056296&postcount=19 ?

Actually, I'm thinking of trying to restore block18 first (while I'm still on the rooted ICS) by dd'ing gb cdrom and then restoring block18 and only then flashing the required GB/ICS parts in order to apply the LATAM OTA.

I'M VERY ANGRY BECAUSE MY GIRLFRIEND REMOVED THE BATTERY IN A VERY VERY BAD WAY (SHE CUT THE BATTERY FLEX CABLE) LAST WEEK, SO I ORDERED A NEW BATTERY FOR $65 USD IN EBAY, TO REVIVE MY DEAD LESS THAN A MONTH RAZR...

Ohhh... and two years ago, she lost my Cliq XT days before the first complete funtional 2.1 ROMs were released... in that time, i spent $300 USD for the Cliq XT, 8GB microsd, and the InvisibleShield...

You can only flash ics for your region. Flashing this may brick your phone.

Yes, its the final release. We'll have a few updates later but this is the initial ics that will be released ota in a few days. First a 2.3.6 will take place in order to get this one.

If you have a block18 backup, you can flash the patched boot and then the en.eu 2.3.6 base to get to the latest ICS en.eu leak which you can then root (since your CID is not original by now anyways) and wait patiently until someone develops the way to get us onto the official leak. Well, that's what I did.

Okay, let's call it Voice recorder - it doesn't make sense.

[Motorola Droid RAZR] ricardofago:
Works perfectly! I just reflashed v2.3.6 through RSD Lite, rooted with Motofail, protected it with RootKeeper and applied the update as described. Performance is amazing, battery seems great too, no bugs. The only thing I noticed is that my RAZR randomly shutted down once, while not in use.

I guess it's not related to this update, cause it happened before both in v2.3.5 and v2.3.6, but it stopped for a couple of weeks, and now happened again. I tried searching around but got nothing solid, some users said it could be due to Smart Actions, which I really use, but I never really tested it. Does anyone know anything about it?

Oh, actually I have only one doubt. As I cannot downgrade to v2.3.6 through RSD Lite, if I screw my system or something like that, re-applying the update should restore the system? Since I reflashed everything to defaults before updating, I'm not sure if the update is incremental or if it replaces stuff.

Thanks in advance.

:D
[Motorola Droid RAZR] theZest:
I encountered this too. All I had to do was clean installing of 2.3.6 Retail Brazilian, rooting (and saving root via Voodoo app) - and then applying the update. It seems that you shouldn't have CWM installed. This is the core problem.

That is ok. But remember to get root in 2.3.6 so you can backup your mmcblkp18 (CID) - if you can't boot and root in 2.3.6 you will need to erase your cid and will need to boot on BP tools for ever

did you ever installed any ICS (exept the first chinese leak with old cdt secure version)? If you did installed the T-mobile 4.0.4 OTA you won't be able to downgrade (completely) to 2.3.6

Yes, I installed the T-Mobile leak.

once you've isntalled t-mobile's version you replaced cdt with a highly secure version that you not allow you to boot older roms
