Well you should downgrade back to the original firmware or you can try and delete some of the larger files on your system.

My phone loads very slow

Hello latronda, Your phone is slow because its old. Apple stopped selling the IPhone 3G, so they stopped developing softwares for that version . You can update your phone, but Apple somehow it makes it slower because they want to make you buy the new IPhone. Also, if you dont have enough storage pn your phone it will make it slower. I hope this answers your question.

My sony ericssion k750i mobile is automatic restart what will i do

this is a software fault so will need new software flashing to it.

you have a chice, keep as k750i or you can flash to w800 as they are the same phone except for software, the button above the joystick would become the walkman button.

ignore about cid 36 as it can also be done to a cid 49 which i will post links to the software that will need to be flashed to the phone, but in any case get a reading off xs++ before you start then make a gdfs backup.

you will need to register to download the files but its free, also you will need winrar2_bing.gif to unpack the files.

then choose your language from this lot:

of course you can keep it as a k750i if you want but being honest, you loose nothing by flashing to a w800 and gain walkman.

incidently if you want to unlock it aswell see here

same procedure except you will not have to bypass security and will be using the files you downloded not the ones shown, if you have any problems there are plenty of people (including me) on se-nse that will help

It depends what provider the phone is locked too. For example, Vodafone may have installed slightly different software to O2 etc.

Virus removal

Hey Friend, there is no need of using an Antivirus software in SE because virus cannot affect SE os. the prob is due to phone m/m overload or due to s/w corruption

Video recording from my SE k750i

Sony Ericsson Phones have been known for those hanging issues, however, we have issues and we have resolutions. Have you ever upgraded the firmware on this phone? Even if the firmware is the latest one, I would suggest a firmware reflash. Don't forget to backup your data before you go for a upgrade or a reflash. In order to know the existing firmware on your phone, press this: > * < < * < * where < is left, > is right. Then go to the Software Info under Service Info. You may go to the official sony ericsson website; select you country; go to support; select the phone; download the Updater Service. And you would be able to find the latest firmware. Cheers
