Hi, please could someone give me an advice? Some days ago the warranty on my S2 ended. So I made root and tried some custom ROMs with kitkat. But I liked no one, so I decided to try MIUI. I had MIUI on my LG 2x and was happy with it. I used the instructions here http://en.miui.com/a-121.html . First I tried to go to the original 4.0.3 - without any problem. Then I installed CWM. and tried to flash MIUI 4.3.28. The installation begun without any problem, but during the install the screen went off and after this I cannot start the phone at all. it doesnt work boot to recovery, boot to download, boot without battery, putting battery during going to recovery ... all instructions from xda or USB jig. Nothing. I tried several USB ports. The phone doesnt react. Doesnt start. Before the installation the battery was on 80%. On xda, http://forum.xda-developers.com/galaxy-s2/general/guide-t2345831 there is info, that when the phone doesnt boot into recovery, into download ... the motherboard is bricked. It is possible in my case return my phone to life? Thanks for your help in advance.
