I recently upgraded to the latest firmware. Since then, I cannot turn on WiFi or Bluetooth. Tried software repair through the Sony Companion program for Windows, tried factory reset. Nothing helped. How could I solve this?

[9001] Wifi and Bluetooth issues

hello everyone, I just registered here for a couple issues with my girlfriend's i9001, it basically can't find Wifi connections, once you click the button to activate the wifi, it shows a green check for few mins while looking for connections and suddenly it deactivates by itself...
I read around about a file to remove via terminal emulator, the bcm_supp.conf one, but I can't find that file...
does anyone have any idea/solution for it? currently she uses internet via 3g (monthly charges) but it would be cool to be able to use the home wifi...
about bluetooth instead, it just can't find other bluetooth devices and vice versa, my nokia 5800 can't find it even if the "visible" option is activated.
ideas?
I'm going crazy about it, I already tried several hard resets and flashed the phone first with 2.3.5 and then with 2.3.6 firmwares... nothing fixed the issues...
thanks in advance for any response
ps: sorry for my english, I'm italian >_<
i had exactly the same wifi issue but flashing a new rom solved the problem. reset and reflashing the same rom didn't help. you tried several 2.3.6 versions?
you might try flashing another modem.

it had the official 2.3.5 (italy), I flashed it with the same firmware and nothing happened, re-flashed it with 2.3.6 (Baltic 13th June 2012) and nothing happened...
noone knows?

wifi problem wiht xperia t and sw2

Hi guys, i have sw2 and xperia t running stock rom 4.3, when my phone and sw2 are connected wifi on my phone doesnt work, when i turn off bluetooth wifi works again, how can i fix it i even did factory reset, i would like to stay on this rom, any solution?
There's no solution for this, I had the same problem like you and I tried everything to fix that problem. Nothing helped so I moved to 4.4 and now I'm on 5.0.2, no such problems
What did you try? 4.3 is running decent so i wouldnt like to change it i was thinking about downgrading to 4.1 but its kinda mehh, what rom did you install, was it buggy?

My T reboots upon mobile data connection

Hi! I have an Xperia T running stock 4.3 and unlocked bootloader and I have a weird issue with it. My phone just powers off every time I connect to mobile data if it's not plugged into the charger or my laptop. It works perfectly on wifi, no problem at all but I don't know what's with the poweroff... I tried factory reset and still the same. Should I reflash 4.3 or another rom and see if the problem fixes? Has anyone encountered the issue too?
Thank you!
