Funkymum

Hi
Ive just bought my DD a sony w850i white which is locked onto Vodafone but she is on o2. Is it possible to unlock this phone & how would I go about it? I asked at my local market today but they said they couldn't unlock it
Any help really appreciated.

There have been a few threads on this in the last few days. You are in luck, it seems that of all the networks Vodafone is the easiest to unlock.

Send a pm to Jaymarsh2005 he may be unable to unlock it a bit cheaper than vodafone

james-73 should be able to get you a vodacode for £10-£15.

i would also consider debranding the phone to get rid of the vodacrap menus and enable flash themes.

whats the best way to debrand the phone?

gaming_guy

i personally use wotanserver. i have debranded 2 w810i's, the 1st one took 10mins to flash the phone and the second one only took 5mins as the files were already on my comp

a while ago, i wrote a guide on how to debrand SE phones. you can find it here

if you are wondering what flash menus are, if you want i should be able to post some pictures of w810i flash menus

Added patch unlock for db2020: W850(i), K800(i), K790(i), K610(i), K618(i), V630(i), W710(i), W710(c), Z710(i), Z710(c), Z610(i) CID 49 and 51

Unlock works only with cable/box RS232 like Cruiser 4 in 1 or a USB Smart 4 in 1. Before unlock please check if phone's battery is charged at least in 50%.



Procedure of unlock DB2020 CID49, 51:

1. Open KKClient v1.54, it will create directory "SLF_FILES"

2. Download SFL files from HERE and unpack into directory "SFL_Files"

3. Files must be in "SFL_Files" directory like for example X:\path_to_KKClient\SFL_Files\*.sfl where x: is your hard drive letter

4. Now KKClient is ready to work. Before unlock of each phone i strongly recommend to check if unlock of certain phone's firmware is possible or not ( for now it works only with USB cable )

5. If application tells you that your phone's firmware is supported please change cable into RS232 in menu, press SETTINGS and then press DETECT, wait few seconds and select COM port and kind of cable/box, then set speed (i recommend 921600), select option "use RS232 communication" and press ACCEPT.

6. If you unlock it for the first time please check if phone communicates by RS232 - press "READ INFO" and connect phone. If you do not have Autoignition cable press shortly POWER button in phone for ignition.

7. If everything goes without a problem you have to choose option "Simlock CID49, 51" and press button "FLASH PHONE".

8. Wait until program finishes - it can take around 50 seconds.



FAQ:

What should you do in case of errors ?

This method of unlocking requires few tricks and it may look like killing a phone. Do not worry - if you see any error please disconnect phone, remove and insert batter and check if phone powers on. If phone does not power on you have to flash phone only with main file (with the same firmware version, which was in the phone) and everything will be ok.

Phone's firmware version was not supported, but I tried to unlock it.

In this situation phone will be like 'dead', because there is no recovery file. You must flash phone only with main file and then everything will be ok, but it will need 1 credit. Because of it i recommend to always check before unlock if certain firmware is supported or not.

if you have a cid49 (and possibly cid 51) phone, you can easily flash the main for free using XS++ once you have located the right main firmware file for the phone you have. but do not flash the filesytem

also i have never used kulankendi, so i dont know what the service is like

I have a cash back contract with Mobile Outlet.Net which seems to be Ok at the moment. I have just ordered a second cash back contract with them, but noe reading the T&C.s for the third time I notive this:

11.1 It is important that you read and understand this entire clause 11 which sets out how to claim your Line Rental Entitlement (Cashback). The Line Rental Entitlement (Cashback) is a single entitlement towards the cost of your line rental, which is paid on a redemption basis.

I have highlighted "single entitlement". Does anyone know, Is this a very sneaky way of saying that I can only have one contract on cash back?

Sorry, I know this is in the wrong thread but the original one seems top have been closed.
