2.1 Update caused WiFi problem, Restore?

I recently updated my X10 Mini Pro to 2.1(O2 UK) and since my WiFi connects to my router and works initially, but after a few mins it will stop downloading data although the WiFi is still connected so in theory it should still work. My wife has the exact same phone, but still running 1.6 and she does not have any WiFi problems, in fact it is much faster than mine when it is working. I have seen this problem posted up here and other forums, but as yet no solutions. What does the update alter to stop the WiFi working properly?
I have tried root, WiFi apps, factory reset(still on 2.1) etc, but it is still the same.
Could I create a backup of my wifes phone(root & xrecovery) then copy this to mine and restore it? Would this return my phone to 1.6 software?
My other option is to flash the generic UK software. Is this reversible? Also does the UK firmware still come loaded with the Nordic keyboard layout?
I'm pretty new to playing with android, but so far I've had a play with adb and root programs so I'm willing to give anything a go.
Any help is much appreciated as I've already spent a bundle using my 3g
FW Version 2.1 Update 1
Kernel 2.6.29 [email protected] #1
Build No. 2.0.A.0.504
Well I flashed it using the UK FW, but it's still causing the same problems. Does this sound like a software issue or a phone issue? It worked fine on 1.6 FW.
My other option is to flash it to 2.0.2.A.0.24 and see if the issue remains, but if it is a phone issue I want to be able to return it.
Could I take a backup from another phone(wifes) and restore this to mine?
I had the same problem with 1.6, then i disappeared upgrading to 2.1, 504, and came back with the 0.24 update.. it sucks :/

Anyone else experiencing an issue where TrackID is no longer working because of the following error message?
"Could not authenticate on TrackID server. For further instructions, please contact Sony Ericsson."
I have the latest stock SE .435 firmware on my X10a.
I've tried wiping the cache and data of the app but the problem still persists.

Update Center not working

Hi my problem is that after upgrading my Z2 to firmware 17.1.2.A.0.314 the update center has stopped working. I am unable to receive any new updates to sony programs like Walkman,Album,Movies etc. Is there any solution to this problem? My phone is not rooted. Thanks.
Temporary solution is to update apps manually. Go here and download APKs and update.

problem with firm ware version 17.1.2.A.0.314

So some time back I made a thread regarding a problem I was facing. My phone would randomly freeze up and restart on its own. I tried hard resettig, repairing using PC companion, flashing using Flashtools , changing SIMs etc. but nothing seemed to fix it. Then I had to arrive to the dreadful conclusion that it was a hardware fault. But 2 days ago I got the bright idea of flashing an older firm ware version (17.1.1.A.0.438) using flash tools without wiping internal data and now the problem is 100% fixed. the phone hasn't restarted even once after a 3 full days of heavy use. So with this I can safely say that the probem is with the 17.1.2.A.0.314 firmware. Has anyone else had this issue? because my friend also owns a z2 and his phone works just fine with the 17.1.2.A.0.314 firmware. Any ideas how to fix it?

[Q] Z2 Home and Recent Apps Keys laggy

hi i got a z2 this week and everything works fine just this one annoying issue. The home and recent apps on screen keys are laggy. Sometimes they work good, most times they lag. The back key is fine.
The phone shipped with 4.4.2 .314 and had the issue right out the box. I updated to 4.4.4 the same night and no change. I downgraded back to 4.4.2 and same issue. Did factory resets etc.
Is there any official word on what is causing this? I live in the Caribbean so sending this to a repair centre is out of the question. Just hoping it's a software issue that can be fixed.
Any help?
Repair via sony PC companion
I found the 4.4.4 update can bug a tiny bit and will slow down heavily, repairing should fix this
if i repair via pcc will i stay with 4.4.2?
i dont want it to update to 4.4.4
Downgrade via flashtool buddy then this problem will be solved
i already downgraded using flashtool.
i was on 4.4.4 and downgraded to 4.4.2. The issue is there on both firmwares.
should i try another version of 4.4.2? if yes, which build number??
okay so here's what i did
initially when i first got the phone it had 4.4.2 .317
i had done the ota update to 4.4.4 and i got all the
popular bugs; camera lag, low notification tones, call problems etc
downgraded bk to 4.4.2, keep in mind the lag has been here thru all this, no matter the firmware
so today i thought id try doing the software repair via pcc. This updated the phone again to 4.4.4. Just this time none of the previous bugs are there and i am happy to report the home key lag is completely gone. The recent apps key had a verrryy tiny lag sometimes but nothing as noticeable as to how it was.
After this i am convinced it is a software issue and hopefully another update in the future would fix it completely. But for now im satisfied.
