^ Putting these images on MEGA and similar uploaders is helpful, but not in the long run. They tend to disappear. If you really want to preserve them, they have to go up on archive.org.

(Or, if you're 100% sure your server will still be up in 10 years, you can upload them there too.)

A question, I have the chance to buy a locked N9, it's not chinese. To flash I must unlock? or I can flash asap?

You would need to "Zeroize device" as here but expect process to take a long time:

so, it's not for newbies? It's this?

eroize device (destroys user data)

The following commands will securely erase your phone such that no data can be recovered later, then restore the operating system and provided content.

Warning: The secure erase feature has not been audited by a 3rd party. Do not rely on it to protect all traces of highly sensitive information from a well-funded attacker. The first part will take a very long time - let it run overnight.

Code:

flasher -f -F main.bin --erase-user-data=secure
flasher -f -F main.bin -F emmc.bin --flash-only=mmc

The code must be written in that way? In main bin and emmc bin have to change something? Once made the zeroize I have to reflash the firmware? which firmware must reflash?

If this pre-owned N9 has not been re-housed and has original SIM card holder the product code (seven character alphanumeric) will be on label on underside. Trouble is that as Nokia's servers long since dead, compromises have to be made on flashing firmware bearing in mind that downgrading firmware is not allowed.

Whilst I posted this "Sticky" three years ago, it is not worth my while updating to 2021 as spare batteries and screws for disassembly much harder to source. Unfortunately flash memory chip is increasingly failing and battery discharges by itself if device left unused, requiring Harmattan flasher to re-charge it sufficiently to boot:

The only picture I had was of the number of system version

This is the only image I have

Whilst I don't recognise PR1.2(30.2012.07-1.367.01.1_PR_367) if I had to guess might be Telcel Mexico. However it will be easy to utilise any PR1.3 firmware as will be an upgrade.

Do not use any firmware but use the PR1.3 global one 001!

Well, again with chance to buy. A locked by carrier N9 seems to be the only option here in Argentina. What is the thing now? Basically the company have a page to unlock phones through IMEI. I get it, and have the unlock code (20 digits). The company says in the web that you only have to put another SIM and write the code and you're done. It's a no go? A risk? Go for it?
