[Tutorial] Installing Cyanogen Mod 7.2.0 on Live With Walkman WT19i

---

This is my first tutorial for installing Cyanogen Mod 7.2.0 on Live With Walkman WT19i. All credit goes to the developers who made all the following and related tools. I simply put together info from various sources. Admins/moderators are welcome to make any changes.

WARNING: Proceed at your own risk! I am not responsible for bricked phones! You might want to do some more research if you're unsure or don't fully understand anything from below

Requirements: ADB drivers:

Fastboot drivers:
win_usb.inf file from http://unlockbootloader.sonymobile.com/instructions
Android SDK(unlocking bootloader):
http://developer.android.com/sdk/
Flashtool(flashing kernel):
http://forum.xda-developers.com/show....php?t=1351309
Zergrush(for rooting):
http://forum.xda-developers.com/atta...1&d=1321435888
Clockworkmod Recovery(flashing ROM):
http://www.mediafire.com/?73xv18tht0e8zt4
WT19i_4.0.2.A.0.58 firmware:


NOTE:Enable "USB DEBUGGING" from Menu -> Settings -> Applications -> Development
>Enable "UNKNOWN SOURCES" from Menu -> Settings -> Applications

1) If you're already on official ICS, downgrade to Gingerbread, root Gingerbread and then install other custom ROMs as follows:
2) Flash any Android 2.3.4 firmware (I've tried this method only with the WT19i_4.0.2.A.0.58 firmware though) using Flashtool
->Select Flashmode, Wipe data, Wipe cache
3) Use Zergrush v3 by DoomLord. Works well with 0.58 version
If Superuser app has been installed, rooting is successful.
4) Install ClockWorkMod Recovery 5.0.2.7-nAa-r2(Ported by nobodyAtall@xda)
5) Make a backup in recovery mode. (see below for howto)
6) Install Android SDK Manager
If Google USB Driver is not visible, install Android SDK Tools Rev 20 first, reopen SDK Manager.
Replace android_winusb.inf-file in extras\google\usb_driver folder with the new one on http://unlockbootloader.sonymobile.com/instructions
7) Unlock bootloader officially from: http://unlockbootloader.sonymobile.com/instructions
Instructions on that page are pretty clear.

NOTE: Unlocking the bootloader the official way will void your phone's warranty and DRM keys will be lost. You may want to use the testpoint method as mentioned here:
http://forum.xda-developers.com/show....php?t=1285285

8) Download Cyanogenmod 7.2 for WT19i (=coconut version) and place it on your SD card.
9) Ensure that the fastboot drivers are installed.
10) Replace stock kernel : Extract boot.img from the Cyanogenmmod 7.2 ZIP file that you downloaded. Now, in Flashtool, select Flash button > Fastboot mode > Select kernel to Flash > Point it to the boot.img file you extracted. Check log in background window for success.
11) Restart the phone into Recovery. Select Wipe data/factory reset followed by Wipe cache partition followed by Advanced>Wipe Dalvik cache.
Then, install zip from sdcard. Select the coconut 7.2.0. ZIP file you placed here earlier.

Wait for about 5-10 minutes. If you're worried, open Command Prompt, navigate to the fastboot folder and run adb logcat to see what's happening!.
And that's it, you're done!

(If the logging process looks like it's repeating itself for more than 10 minutes, remove battery restart phone, and see if Cyanogenmod now boots up(again, will take ~5 minutes). If it does not still boot(rare case), repeat step 10. Make sure you download the CM ZIP package from your computer)

If you get an 'assert' error (Status 7 error) then, edit the file updater-script in your cm7.2.0 ZIP file\META-INF\com\google\android\. Remove only the first line (ending with a . Now repeat step 10 again.

Extra: To use Google services, you need to flash the gapps.zip similar to the way you did CM 7.2. However, do NOT wipe cache do NOT wipe data or anything! To install, simply boot into recovery, install zip from sd card and choose the gapps ZIP file. Later, Restart phone

How to enter recovery mode on the WT19i:
Turn off phone. Turn it on again. As soon as you see Sony Ericsson logo, keep tapping Volume Down button repeatedly. (Once you are familiar, you'll realize that even 1-2 presses can do the trick)

You do not need to root and install Recovery in the first place, I mean skip steps 3, 4 and 5.
Backup can also be made in the same recovery, which is included with kernel, right before wiping and installing the ROM.

I would just install any Android 2.3.4 firmware, then unlock bootloader, install custom kernel, backup, then wipe, then install.

And if you unlock bootloader officially, then do not forget your phone's warranty will be void and DRM keys lost.

If you succeed with official bootloader unlock, then fastboot drivers are already installed, no need to worry about that

And before ppl go crazy - First boot does take a while, as all the caches need to be recreated.


This tutorial can also work for other custom ROMs aswell, because the process is the same, the only different thing is the kernel and the .zip file.

Right I meant that to install CWM!

Right except that I had problems with using Zergrush v2 and v4. That's why I thought I'd mention.

Yes, but that would entail downloading the android_winusb.inf-file from the mentioned official site, wouldn't it?

And before ppl go crazy - First boot does take a while, as all the caches need to be recreated.

Oh, but how common is it for a WT19i to take more than 10 minutes at boot? I did this on two other friends' WT19is; both of them took around 3 minutes. (Obviously i did something wrong the first time on my phone)

Anyhow,thanks for the constructive comments!Editing it accordingly!

You do not need CWM in the first place. You can make the full Nandroid backup AFTER flashing custom kernel and BEFORE wiping and installing the ROM.

You don't need root to be honest.

What's your point? If you unlock the bootloader official way and it succeeds, you do not have to deal with the drivers anymore, as they have been installed properly and they're working

I didn't mention about minutes. Some ppl are not aware of that, so it was just a small note for them.

Right! The custom kernel would provide a recovery (which isn't present on a stock kernel for our phone), right?

I shall edit the title to something like 'Root and install CM...' where I express the opinion that rooting does have advantages too!

Custom kernels already include recovery and stuff needed for root.

Rooting is already included in custom ROMs, if not then custom kernel does the job and roots it automatically. You don't need to root it by yourself

didn anyone tried latest nightly

There is a stable rom for LWW listed on the cyanogen mod downloads page. Is it really stable? I'm asking this because when you select 'all' and 'stable' on left panel on that site, there is no stable rom listed for lww! This is very confusing.

Yes the version of CyanogenMod 7.2.0 listed on their site is stable and indeed the one used in this thread for reference. Click coconut in the left hand pane(that's the codename for LWW) and then selecting stable. (Alternately just go to http://get.cm/?device=coconut&type=stable)

I just installed Cyanogenmod today and it's fantastic!
