Network Problem

I bought a W810i off Ebay with a Network problem some it work some it didn't. Put new Aerial and check Sim points fine. it look if the phone has been debranded, because opening page didn't match any I knew. So decided to flash it using XS++, now it doesn't find any network. Tried a T-Mobile sim and O2 sim, both have bar reading in top corner but no network. Tried a SEUS but it doesn't recognize the phone, presumably because it been debranded. So anyone now how to sort my Network problem.:(

ebay phones more turouble than there worth u will have to check the imei hasnt been blocked u can check it here CheckMEND - The Global Second-Hand Stolen Goods Database for Public Trade Checking

Did as you said got it check out and it not on any Block list.

were did u take the iemi from the phone or back off the houseing

Took the Imei from the phone.

are the Aerial pin not bent and touchin the pcb okies

The pins are straight are on the Mother board and the aerial looks good.

what icons are on top top part off ur screen any

The start up page is Reception strength in the top left hand corner with the icon of GPRS and GSM icon above it . Right hand Corner Battery Strength and in the top Middle Network. After had put the phone back together after checking the pins, I put sim card in and got a bar reading in the top corner and the network logo up! lasted about a minute and nothing since. By the way Philzfog I read one of your reply to someone who had put in the wrong GDFS I have done the same think about Two months ago but I had not back up the original so have a mix IMEI so don't know how to fix. Would changing the IMEI to match the one in GDFS work.

Sorry I forgot to mention When I first got the phone there was nothing on start up page except white Block with writing it . That the reason I decided to flash it and put in the W810 R4EA031 main and fs.
