Hello to all, I made the procedure to get my Xperia X10 mini from 2.0. to 2.1. firmware as described here : http://www.xperiablog.net/forum/resources/xperia-x10-mini_e10_2-1-1-a-0-6_global_generic.72/ I had Sony Updae and Companion installed so i guess i had drivers insatlled. Debug was checked. all went as described, except that my phone just doesn't start anymore :-( No way to recover from Sony Update nor Companion since the phone refuses to start. I retried to flash the firmware, but it now says that the USB debug is unchecked -and no possibility to check it again :-( I disconnected the battery, no result. Note : the phone seems to start though, the screen get dark lighted (the dark screen gets slightly lighted) during few seconds (4 or 5 seconds) then the phone seems off again, for around 20-30 seconds, then it starts again same way, and doesn't stop this on-off-on-off... until i get the battery disconnected again. No way to have it stop with the on/off button. This is the log of the Flash Tool procedure : 21/039/2013 18:39:37 - INFO - <- This level is successfully initialized 21/039/2013 18:39:38 - INFO - Flashtool Version 0.9.13.0 built on 2013-06-04 22:50:00 21/039/2013 18:39:44 - INFO - Device disconnected 21/040/2013 18:40:21 - INFO - Selected E10i / 2.1.1.A.0.6 / Sony Ericsson 21/040/2013 18:40:21 - INFO - Preparing files for flashing 21/040/2013 18:40:42 - INFO - Please connect your device into flashmode. 21/042/2013 18:42:00 - INFO - Device connected in flash mode 21/042/2013 18:42:01 - INFO - Opening device for R/W 21/042/2013 18:42:01 - INFO - Device connected in flash mode 21/042/2013 18:42:01 - INFO - Reading device information 21/042/2013 18:42:01 - INFO - Phone ready for flashmode operations. 21/042/2013 18:42:02 - INFO - Current device : E15i - CB511KM1VR - 1242-7327_R3B - 1236-9291_2.0.1.A.0.47 - WORLD-1-8_2.0.1.A.0.47 21/042/2013 18:42:02 - INFO - Start Flashing 21/042/2013 18:42:02 - INFO - Processing loader.sin 21/042/2013 18:42:02 - INFO - Checking header 21/042/2013 18:42:02 - INFO - Flashing data 21/042/2013 18:42:04 - INFO - Loader : S1_Loader_Root_8e35 - Version : R4A045 / Boot version : R8A027 / Bootloader status : UNROOTABLE 21/042/2013 18:42:04 - INFO - Processing kernel.sin 21/042/2013 18:42:04 - INFO - Checking header 21/042/2013 18:42:04 - INFO - Flashing data 21/042/2013 18:42:07 - INFO - Processing fota0.sin 21/042/2013 18:42:07 - INFO - Checking header 21/042/2013 18:42:07 - INFO - Flashing data 21/042/2013 18:42:08 - INFO - Processing fota1.sin 21/042/2013 18:42:08 - INFO - Checking header 21/042/2013 18:42:08 - INFO - Flashing data 21/042/2013 18:42:08 - INFO - Processing amss_fs.sin 21/042/2013 18:42:08 - INFO - Checking header 21/042/2013 18:42:08 - INFO - Flashing data 21/042/2013 18:42:09 - INFO - Processing amss.sin 21/042/2013 18:42:09 - INFO - Checking header 21/042/2013 18:42:09 - INFO - Flashing data 21/042/2013 18:42:21 - INFO - Processing cache.sin 21/042/2013 18:42:21 - INFO - Checking header 21/042/2013 18:42:21 - INFO - Flashing data 21/042/2013 18:42:21 - INFO - Processing system.sin 21/042/2013 18:42:21 - INFO - Checking header 21/042/2013 18:42:21 - INFO - Flashing data 21/044/2013 18:44:08 - INFO - Processing userdata.sin 21/044/2013 18:44:08 - INFO - Checking header 21/044/2013 18:44:08 - INFO - Flashing data 21/044/2013 18:44:17 - WARN - This file is ignored : simlock.ta 21/044/2013 18:44:17 - INFO - Ending flash session 21/044/2013 18:44:18 - INFO - Flashing finished. 21/044/2013 18:44:18 - INFO - Please unplug and start your phone 21/044/2013 18:44:18 - INFO - For flashtool, Unknown Sources and Debugging must be checked in phone settings 21/044/2013 18:44:18 - INFO - Device connected in flash mode Thank you very very much for your help.
