Hello, I have a problem and I need advice. I have Sony xperia Sola. I have a new version of CyanogenMod and last week I download this new firmware from XDA forum http://xdaforums.com/xperia-u/sola-development/rom-unofficial-cyanogenmod-11-0-t2627210.
I have downloaded this firmware and I recorded into the phone via fastboot file boot.img. I disconnected my phone and I started it.
I press the volume - button.

I move by this manual:
1 Download the zip(s).
2 Extract boot.img and flash via Fastboot
3 Boot into recovery
4 Perform a NANDroid backup of your current ROM.
5 Full wipe[data, cache, format system].
6 Flash CyanogenMod Rom Zip.
7 Optional: Install the Google Apps addon package.
8 Reboot.
but I finish at number 3, the recovery mode didn't go (I didnť get into recovery menu)

I tried to record the old boot.img into the phone but it did not respond. However much I try to start it, does not respond. It is not charged on the charger or turn on...The biggest problem is, that my phone did not connected with PC and it is impossible activate fastboot mode. Please advice how to start and fix my phone! I'm apologize for my english! Thank you for your advice!

First make sure the phone is turned off, press power + volume up untill you feel (1+) 3 vibrations, then try fastoot.
Before fastboot, try to power up, and spam the power every secong or so to enter recovery, if that doesn't work, turn it off again and flash former kernel.

Thanks for your advice, but my phone is 100% turned off. I have a problem with turned on. The phone does not respond. I have a problem charging my phone. I don't get into recovery menu and fastboot mode don't start. If I try connect my phone with PC (hold volume up) the LED should be light violet, but the LED constantly lit red and the phone can not connect with PC. The phone is absolutely dead. Thanks for some othe advice.

Try connecting in flash mode to check if the phone charges in this mode.

When trying fastboot or flash mode keep the buttons pressed longer. I haven't seen a violet led notification before. What should it mean?

Thanks for your advice! My phone is OK, now! I start it by Flashtool. Over and over I tried to connect it to flashmode and I was eventually succeed. I succeed to upload there old official firmware version through which I managed to charge the phone and run it again. I think, that problem was in the phone's battery. It was empty and not charged. So it was problem to get the phone to flashmode. I do not know how I succeed to finally connect the phone to PC when the battery is empty, but the phone works.

Phone charges in this mode, but very very slowly and after about a few minutes, the phone turns to the splash screen and then turn off and stopped charging. :/ So I think that the flash mode did not go to start due to low battery.

It did not work even when I trying the buttons pressed longer. Violet led notificaiton is only in fastmode (phone is connect with Pc). Led notification is the right of the logo Sony above the display. I saw the violet led notification many times!
