I have successfully rooted my Galaxy SII i9100T with Jelly Bean 4.1.2 (using ironass's most useful Guide), and then removed the yellow triangle with Triangle Away. I then attempted to install CyanogenMod CM11 M10 Android 4.4.4 KitKat firmware, but a problem with the file aborted the installation with Status 7. Since then booting the phone always goes straight to Recovery mode.
I have tried:
* wiping cache, dalvik cache and data in Recovery mode and then re-booting;
* powering it down and restarting the phone, including removing the battery to power it down;
* entering download mode and exiting from there using VolUp + Power;
* Re-rooting the phone (with Odin307) - which I think was successful because I received the "PASS" message, and the yellow triangle has returned.
None of these actions have made any difference: The phone is always re-entering Recovery mode.
I would appreciate any advice on next steps to get my phone back into use.
