[Motorola Droid RAZR] koreanoc:
A little tutorial for the Razr LATAM

Hi,

Right now I'm running the T-Mobile ICS in my LATAM Razr (Telcel Mexico), I've been reading that some people are having trouble getting it to work, so I will explain what I did.

First, I was running GB retail from Brasil (6.5.1-167_SLC-M37_SIGNLATAM_USASPYDRETBRB1B2B5B8B8LA030.0R_USASPYRETBRLA_P021_b8cb72a7e2_HWp2b_CFC_fastboot.xml.zip). You have to be rooted, of course, if you aren't use motofail.

BEFORE YOU DO ANYTHING:

* Take in mind that your phone will have to boot always using the bp tools option located in the bootloader. If that doesn't bother you, go ahead and enjoy ICS as I am right now.

* In this tutorial, when I refer to Recovery mode, I'm referring to stock recovery mode.

* With this method you CAN go back to GB if you wan't and take away the customerID error by changing back the mmcblk1p18.

1.- I did the mmcblk1p18 trick from the Chinese leak. You have to download the file mmcblk1p18-go.rar, unpack it to your sd card. Open Terminal Emulator and type: su

After that type the following:

cat /dev/block/mmcblk1p18> /sdcard-ext/mmcblk1p18-back

This will backup your original file to your sd card.

After that, you have to type the following command: cat /sdcard-ext/mmcblk1p18-go> /dev/block/mmcblk1p18

This will copy the file you downloaded to the phone.

2.- Flash the chinese ICS 4.0.4 (fastboot-p2b_spyder-umts_spyder-user-4.0.4-6.7.2_gc-120-175-release-keys-chinaretail-cn_chn.tar). You have to extract the folder contained in order to RSD lite detects the xml file contained within. Open RSD lite and select default_flash.xml, and click on the start button.

After it flashes, it will reboot the phone, and it won't, but don't worry, power down the phone (power+both volume keys until you see a flash on the screen), turn it back on using the same method, which will bring you to the bootloader menu, then you have to select recovery. In recovery it will start automatically flashing a radio.img. When it's done, select reboot to system. You'll see a CustomerID error, this is caused by the modification made in step 1, but don't worry, turn the phone off, and turn it on with the 3 keys combo, in the bootloader menu, you will have to select bp tools (and as uncomfortable as it will sound, this will have to be done EVERYTIME you reboot your phone).

Your phone will boot into the chinese ICS leak.

3.- After you boot into the chinese ICS, reboot into recovery, and do a wipe / factory reset (This is very important!!).

Then boot into FASTBOOT. When in fastboot, go to RSD lite and flash the GB from T-mobile (Remember, everytime the phone reboots, you have to turn it off and turn it on with the 3 key combo and select bp tools, otherwise you'll be stucked with the customerID error).

When you boot into the german GB, root it with motofail, and then download Voodoo's OTARootkeepr from the market and open it, tap on the preserve root button, and then on the temp un root button.

Unzip the files contained in the German ICS (672.152.43.en.EU.zip), and put them in your sd card. There is a .zip, a .crc and an .apk.

4.- Now that you have the files needed in your sd card, boot into recovery, and select apply update from sdcard (NO WIPE THIS TIME!) and select Blur_Version.651.167.21.XT910.T-Mobile.en.EU.zip

Wait until finished, and reboot with the same bp tools method I've been mentioning before.

5.- To restore your root, open OTARootkeeper and tap on restore root, and that will be it. Enjoy ICS. If your phone freezes on the first boot, when it says it is initializing apps, just turn it off with the 3 key method and turn it back on with the bp tools method, then you'll boot just fine.

I hope this help you.

Cheers and thanks to the people from this forum and grupoandroid.com, whom made this tutorial possible.
