Nokia N9 downgrade...
 

I got my N9 3 months ago and it came with PR1.0, Austria, 059J200.
Then I did a software update to PR1.1 but there was a call bug and I flashed it with PR1.1.1 (UAE):

It was a good update, no call bug and I was happy with it.
But now, when I saw PR1.2, I knew that I have a to wait a lot of time to get to it.

I used to have Symbian Phones (N8, E7...) and I always did software downgrade, but only with one software version. If I had f.e. Belle and I wanted to go back to Anna, I was able to downgrade flashing it with Scandinavia 11.005, and then I was able to flash it with Anna.

Since yesterday I checked for update but nothing. Then today I realised to try to downgrade with what I call a base software version of N9. I found Central Europe Black 16 GB 30.2012 - 001 version which I think has that **** inside than can allow me to do a downgrade, and I think that's is the only one that can allow us to do a software downgrade.

I flashed with it and now my phone says I have PR1.2 30.2012...001.


This is how I did it:

Enjoy!

wait wat? i think u got a bit confuse, u are NOT DOWNGRADING, in fact you are UPGRADING the software, and last time i check YOU CANNOT DOWNGRADE n9

Re: Nokia N9 downgrade...
 

Do you see the last 3 numbers there? 335...
Going from Legacy 335 to Legacy 001 is a downgrade.

Re: Nokia N9 downgrade...
 

But from 1.1.1 335, to 1.2 001 IS an Upgrade.

Re: Nokia N9 downgrade...
 

On N9 the flasher will check complete string, and if it detects a bigger number then it will give you an error - downgrade disallowed.

@ENNINE: You may want to remove your IMEI from the snapshot. Cheers!

Re: Nokia N9 downgrade...
 

From

22.2011.44-2.335.4.PR_335

to

30.2012.07-1_PR_LEGACY_001

IS an upgrade

Re: Nokia N9 downgrade...
 

Second part of the string.

Re: Nokia N9 downgrade...
 

If the first part of the string is greater, the second part is ignored and flashing is allowed.
That's the way it works.
Upgrade.
Case closed.
