[Q] Very big problem

Hi xda commuity!
I have searched through your forum and have not found my answer... I am then asking for your help.
I have a Xperia T (LT30a 9.0.9.141 if I recall correctly) and it won't boot. Son logo appears, then vanishes.
I have tried flashing back the bootloader as well as the entire system, but I always get an error from flashtool.
I need your help folks.. Thanks in advance!
P.S. : The reason why my phone is stuck there is that it wasn't apparently rooted the good way..

[Completed] huawei 525 u00 stuck on logo

hello everyone!
im basically new here and i badly need your help. i have the above phone model and i started having problems when it wont allow me to uninstall apps from my phone. but everytime i restart the phone, the apps would still reappear. i tried doing a factory reset, but after rebooting, it didnt erase everything. after trying several times, i decided to stop and just remove the battery and give it a rest. after a while i turned it back on, and its stuck in the huawei logo. tried doing hard reset again but now its giving me a message "update exception EMMC is readonly, you cant update your system." now i dont know whats the next step that i should do. I NEED HELP! Thanks everyone!
