[Q] Custom ROM: Stuck at Sony Logo Screen topic

I am new to Android mod. I was trying to install CyanogenMod for Sony LWW from here: http://download.cyanogenmod.com/?dev...ut&type=stable

I installed CWM Recovery, and took a backup that gave me: cache.yaffs2.img data.yaffs2.img nandroid.md5 system.yaffs2.img
I followed the following steps:

0. Downloaded the ROM and placed it on your SD Card.
1. Booted into CWM Recovery
2. Wiped Cache, Wiped Data and went to "Mounts and Storage", and formatted "/system". Also, went to "Advanced", and wiped "Davlik-Cache"
3. Went to Install zip from SD.
4. Selected the Downloaded ROM zip file.

The installer crashed at assertion:

Code:

---

assert(getprop("ro.product.device") == "WT19a" || getprop("ro.build.product") == "WT19a" ||
      getprop("ro.product.device") == "WT19i" || getprop("ro.build.product") == "WT19i" ||
      getprop("ro.product.device") == "coconut" || getprop("ro.build.product") == "coconut");

---

So, I had to reboot. When I rebooted... it was stuck at welcome screen.

I tried to go to CWM Recovery by holding volume-down key at boot. Nothing happened. Removed/replaced battery, tried again nothing happened.

So, I decided to follow "turning brick into smartphone" article here: http://forum.xda-developers.com/show....php?t=1568792
I installed FlashTool on Ubuntu 13.10 as described here: http://duopetalflower.blogspot.in/20...ntu-linux.html
But Flashtool does not detect the device.

Can someone guide me how to fix this?
