I've been trying to use flashtool to flash the 290 ftf, but I can't. All I can do is flash the system.sin and userdata.sin in fastboot mode. I can't get to flashmode. When I plugin my usb cord and hold the Volume Down button, the LED just flashes from green to red and then turns off. The Flashtool acts like it got into flashmode, but then halts. It never gets passed 0%. It looks like I can't get into flashmode. I've tried everything. Any ideas?
The second solution worked for me. However, I did wipe data or else cm10.2 won't boot.
1. Be on 290 with UL bootoader.
2. Flash boot.img from cm10.2
3. Enter recovery and factory reset.
4. flash cm10.2 and gapps.
5. Boot in to cm10.2 and ignore initial setup process. Just skip skip skip.
6. When in home screen, open phone and dial *#06#. If you see IMEI lots of zeros, your OK.
7. Now turn off phone and ftf .257 but exclude system and kernel. Uncheck wipe data.
Yes with 4.3 or 4.4.2 stock i have IMEI, and also with cm11-nightly!

Flashing using flashtool
Flash EVERYTHING in the above ftf by @[NUT]
Flash EVERYTHING in this ftf, (use the defaults) it will do the downgrade below so you will end up on .532 with a working IMEI ready to root with bin4ry's tool http://forum.xda-developers.com/devd...ct/dl/?id=3442
You will end up with a device that thinks it is a C6833 but when you flash 4.3 or newer (.290 or .136) just use the one for your real model and the model number will be restored.
It is quick and simple then just flash the newest 4.2 FTF if you want to use CM 10.2. If you are happy with CM 11 just stay as you are
