[philzfog]

i think in all fairness ur goning to end up buying a nother problem and waisting ur monine as if u try to take the ribbon and key pad off that phone u are watching u may break it if it was me i would just change the 2 parts i said to do and as long as there put back on prply and u dont break the lcd all will be fine

Hi again,
Well I got the parts and stuck them all back in but no luck. It started blinking a white screen which may have been some problem from when I played around with the firmware before I started this thread. Anyways I tried playing around with the firmware again and I think I may have finally bricked the phone. It won't even turn on now or connect to SEUS or XS++. This is the final part of the XS++ log before it stopped working (I updated the GDFS with one from the downloads section of this website and XS++ says it worked fine????). Any ideas??? thanks

I just read on a forum that you might know how to fix it (I Killed My W850i with Wrong Gdfs...dead W850i....repair Gdfs.. - SE-NSE Forums - Sony Ericsson Forum and Community). Ok so I didn't know the GDFS was unique to my phone but at least I made a backup of it right!!!!!

So could you please give me some instructions on how to get my backed up GDFS back onto the phone eventhough it won't turn on and won't connect to XS++. I think after that I need to get the firmware sorted out (how do I pick which to use and what does the filesystem mean)?

Thank you so much for your help so far - I wish I knew as much as you.

show as a k700 isnt any firm were p[roblem just u havent fited the parts right thats all and now if u have wrote a gdfs that wasnt urs uv killed it and if u dont have a back up u will have to use D-Ultimate Unlocker to fix it

[philzfog]

add ur gdfs back up to the mics box on se tool lite then press wright gdfs and con holding the 2 and 5 buttons on ur phone then it will right it back

after I put the new parts in it turned on and just blinked a white screen on and off every few seconds and I couldn't turn it off without pulling the battery out. Does this suggest a hardware or software problem?

I did backup my GDFS so will try this when I get home from work. What do you mean by con? Will it write to my W850i even if it won't turn on be recognised by SEUS or xs++?? When I plug it in to charge nothing seems to happen? thanks

[philzfog]

con/ means conect ur better to wright it back with se tool buddie as xs wont work

[jchong]

ok I will give that a go after work. Can you tell me what you think the problem was when it would turn on and blink white on and off? Is that software or hardware problem?

[philzfog]

after u wright back the gdfs thats for that phone if it still shows as a k700 its a hardwere fault double check the ribbon is on was it used parts or new ?
