I am trying to update my e71 firmware to the 400 version.
I bought the unlocked phone from Amazon in the US, and changed to the product code 0567045, so that I can go for the newer version firmware.
But when i tried to update using the NSU, it said the service provider hasn't approved yet, which mine is T-Mobile.
I believe that error is caused by using a product code for a different item type (RM-346). You need to find a code that is compatible with your RM-357.
Not to hijack, but on a related note 0569371 is showing version 400 yet again. Being they've pulled it at least twice previously, I'm a little nervous to update in case it has more bugs.
