settings > apps > all > camera > clear everything > restart your phone

i already tried this and other possible by disabling camera restarting phone and clearing everything of camera and restarting but as usual when open the camera immediatly it say error camera not available

Are you using Flashtool to upgrade and downgrade and if so have you got USB debugging enabled and unkown sources ticked - Also in Flashtool are you ticking the box to wipe data and cache plus after your 1st boot go into backup and reset and do a Factory data reset - I don't know why if at all this factory reset helps but many say to do it

for upgrading i am using pc companion and for downgrading i used flash tool with us debugging on and unknown source ticked .rest the options in flash tool remains as they are default

Ok after you have upgraded via PCC you may need to do a factory reset which will make your phone think it's a fresh install like ICS when you downgraded - A lot of members on here are experiencing issues of a simalar nature, My son only has one issue which is bugging him and thats when he takes photo's close up of an object and the auto flash deems it is needed then any reflective surfaces turns the photo a purple colour turning the flash off fixes it or moving a little furthur away fixes it also

ok now i will update again and after update i will do factory reset and post results then

I'm not saying it will work or fix your issue but it more often than not does help and fix issues

thats bad it means i cant install update

also i heared sony released fixed update for jelly bean

the first one has version 6.2.b.200 and the one with update is 6.2.b.201 or some thing like that but i am still getting 200 one is this true sony release any such update?

Did it fix your issue and there is another firmware .211 that I know of but honestly i've tried both and they are both the same in my opinion if you want to try the .211 firmware using flashtool then
