Re: [Problem]Flashing Nokia N9 - downgrade disallowed
 

I have the same issue with my N9. The version I'm trying to install is 20.2011.40-4.339.2 and the model is 059L7S2.

Which other versions can I install?

Re: [Problem]Flashing Nokia N9 - downgrade disallowed
 

I've changed the Slovenian code to Balkan, but update via Nokia Software Update fails. It shows the updating progress bar for a second and the it turns off. If i try to flash it i get the error code 10.
The only firmware that it let's me flash its the one is already installed.

Re: [Problem]Flashing Nokia N9 - downgrade disallowed
 

Hi, while flashing my N9, after a "apt-get autoremove" of death which left my phone bricked, I am seeing "Downgrade disallowed" but to my knowledge the versions are ok.

Basically it's a N9 coded 059L4L3, Argentina. I try to flash the firmware:
DFL61_HARMATTAN_20.2011.40-4.348.1_PR_LEGACY_348_ARM_RM-696_PRD_signed.bin

obtained from navifirm (I've tried both production-external and nokia-care)

and I am getting the following error:


desktop:/float/download/n9/firmware/image_20_nokia_care$ sudo flasher -f -F DFL61_HARMATTAN_20.2011.40-4.348.1_PR_LEGACY_348_ARM_RM-696_PRD_signed.bin -F DFL61_HARMATTAN_20.2011.40-4.NOMAPS_EMMC_NOMAPS.bin -R

ERROR: Failed to flash images


From what I can tell it's the same version already in the device, DFL61_HARMATTAN_20.2011.40-4.348.1_PR_348, could anybody help me understand why am I seeing "Downgrade disallowed", and more important how to fix it?

The same error is shown when I don't use the eMMC image. For the record I am using Linux Ubuntu 2.6.38-8-generic 64 bits, and the phone isn't booting.

Thanks,
Sebastian.

Re: [Problem]Flashing Nokia N9 - downgrade disallowed
 

HI i have the same problem my code is 059J217 and when trying to reflash with pr 1.3 sw 40.2012.21-3 it always says downgrade disallowed error status 10 and the code of the country is 006 ... please Help

Re: [Problem]Flashing Nokia N9 - downgrade disallowed
 

Most likely you have updated your phone with SSU, and timestamp in over the air variant update is never that on full flash image, so you will always get downgrade disallowed message (this has been explained in multiple posts before), but luckly for you, you can just upgrade to pr1.2 or pr1.3 instead of pr1.1.

Re: [Problem]Flashing Nokia N9 - downgrade disallowed
 

i have a cyan N9 16 GB , forgot the security code so i had to flash my phone so i zeroize the device with this command
"flasher -f -F main.bin --erase-user-data=secure
flasher -f -F main.bin -F emmc.bin --flash-only=mmc"

this appeared " erasing this may take a while " but when i entered second command it replied with "error code 10 security failue"
" downgrade disallowed "
product code is 059K0Z8

HELP !!
Thanks

Re: [Problem]Flashing Nokia N9 - downgrade disallowed
 

@Danishgr8: without knowing which version+variant you were flashing and what version+variant you had on your phone, it's not easy to help you.
Post some details, please.

Re: [Problem]Flashing Nokia N9 - downgrade disallowed
 

i was installing 40.2012.21.3 release variant -

DFL61_HARMATTAN_40.2012.21-3_PR_LEGACY_001-OEM1-958_ARM.bin

DFL61_HARMATTAN_40.2012.13-7.EURASIA_EMMC_EURASIA.bin


i guess these are the latest version available for my phone from navifirm ..

Re: [Problem]Flashing Nokia N9 - downgrade disallowed
 

So are you sure that your device *currently* has also that version & variant ?
Because if you currently have *any* other variant for PR 1.3, that would explain the 'downgrade disallowed' message.
You should be able to get the current version with "flasher -i" (if that value hasn't been already overwritten with your latest attempts).

Re: [Problem]Flashing Nokia N9 - downgrade disallowed
