Hey guyz its very simple to upgrade..change ur product code by NSS.and use this product code 0529835..Download the « NSS » software in order to change the phone’s product code. This is a shareware program that you can download on the site of its author here.Download the attachment file.

NOW WE CAN BEGIN:
Install NSS[/SIZE][/SIZE]
Install NSU
Connect your phone and wait for Windows to install the drivers.
Open NSS and click on “Scan for new device” on the right-upper part of the window
Click on the icon « Phone info »
Click on “Scan”

As you can see, now you can change the product code (on the right of the « phone info » window of NSS). For a Nokia N73, type the product code 0529835 and then mark the case “Enable”.
Now press “Write”, and your phone’s product code will be changed (you might think that nothing happened, because the phone is still in normal mode, and the changing of the product code only takes a couple of seconds, but don’t worry, the product code changed !).
Close NSS and you can proceed now with the NSU flashing!!!

you lie. check this one

u entrd wrong product code..see the product code which i have given..

change ur product code guyz by NSS whic is attached..product code is 0529835..if u dont believe check it out.

Yes if you put 0529835 as the product code you do get the V4.0723 firmware come up but this changes phone to RM132 which is non 3G version

i'm so sory bro,,,,,,

DO NOT use the above mentioned product code to update ur firmware....the code is fr N73 RM-132.....that is the non 3g version....I used the above code to upgrade although the phone got upgraded but now its RM-132 and not RM-133 n there is no 3g support anymore.....i dunno if 'il b able to revert back to the 3g one (rm-133) anytime sooner as the NSU says that v4.0723.2.01 is an older version although its not available yet but it will be older to this one as the last 3 digits are 2.0.1 in rm-133 and 2.1.1 in rm-132.....

I've Updates via NSU with code0529835. My original code is 0529820
now my phone version is
V 4.0723.2.1.1
07-06-2007
RM-132

I've try to updates again with many number code, but NSU say your phone already has the latest supported up. No updates needed.

Please help me to reinstall to

RM-133
Sorry for my bad english

You should wait for newest version or should go to repair centre

Code 0527009 gives version 4.0726.2.0.1. There is very little information on this firmware but I think it's RM-133. I'm still a bit apprehensive about changing my product code though.
