Hey, quick question,

Added by charles mosa 6 months ago

What do I need to download for flashing the galaxy note 2 N7100?

I tried following your options, to check the checksum but it says no public key available...

is that normal?

Oh and also, I am curious to know how to connect it to wifi when 6.0 comes out.

and last thing, will it support a 256gb micro sd card or even 128gb micro sd card?

Yes, it is. As long as you don't have the release public key in your local GPG keyring.
You need to download the public key, in order to be able to verify that the signature on the contents you download is correct.
Further instructions on how public key cryptography works are available here
While practical instructions on GPG are here

In order to verify Replicant's images you first need to download the release key(s).
At present, only Replicant 4.2 is distributed and signed officially by the Replicant project.
You can find the public key ID and fingerprint here

You can import the key into your local keyring by doing:

gpg --recv-keys <ID-of-the-key>

It is essential that you check the key's fingerprint, after receiving the key!
To do so, type:

gpg --fingerprint <ID-of-the-key>

and then manually verify that the fingerprint of your locally imported key matches the one on this webpage

This is a way to ensure you received the right public key, and that it is still intact.
After you do so, you can redo the verification steps you already tried, and if everything is correct, then you should see that the signature verifies correctly.

The same thing applies to Replican 6.0, but for the moment you need to use Wolfgang's public key, because there isn't currently any officially signed image (but it's going to be release very very soon).

Oh and also, I am curious to know how to connect it to wifi when 6.0 comes out.

You will be able to use RepWifiApp, which is a convenient way to connect to wifi using an external adapter.
Or, you can use some shell scripts, which do quite the same thing.
Instructions to do so are here

Keep in mind that when Replicant 6.0 gets officially released, it will contain RepWifi by default, so there won't be no need to download the "unofficial" apk.

Happy hacking!

Thanks for the info but one other question, why does the key say it is valid but untrusted?

The key looks as it says it should but I still wonder the above question.

I am assuming by the way this is easy to install through debian 8 or in my case debian 9 right?

This exactly expected behaviour.
When you import a public key in your local GPG keyring, by default it has no trust level.
In synthesis, the trust level is an attribute that you yourself give to the keys in your keyring.
This means that you can tell GPG what different levels of "trust" you have in each key it holds.
For a correct usage of the feature, I strongly suggest you follow the GPG guidelines I linked in my previous post.

In short, it is normal that once you download a key, before you edit it giving a desired level of trust, the key is marked with no trust level.
In general, this is not an issue, as it only means that you haven't yet assigned a specific trust level to that particular key. But this doesn't affect the validity or the correctness of the signature verification in itself.
What GPG is telling you, is that the signature you just verified is cryptographically valid, but that you haven't told GPG if you trust the public key in the first place.

For more info, I strongly suggest once again that you check out how public key crypto and "the web of trust" work, and how GPG handles them.

I am assuming by the way this is easy to install through debian 8 or in my case debian 9 right?

Yes, as long as you read instructions carefully and you understand what you are doing, as always :)
If you have any doubt, I encourage you to ask on this forum or in the mailing list, and you will get help!

Happy hacking,

Thanks for the info, but tell me, will it support a 256gb micro sd card?

and also, will the battery life be more on replicant then say, android?

Those be my final questions. Or at least I hope they would be. heh.

RE: Hey, quick question, - Added by Kurtis Hanna 5 months ago

The battery life will likely be worse on Replicant since 3D graphics acceleration isn't availalbe with free software, which causes the CPU to work harder than on other android ROMs.

I'm not sure if 256GB is supported. I think that Samsung recommends a maximum of 64GB, but I also saw that someone modded their Note II to have it run with a 256GB SD card with a microSD to SD card converter. http://www.phonearena.com/news/Samsung-Galaxy-Note-II-mod-adds-256GB-storage-much-more-battery-life_id45007

Please let us know if you test out a microSD car larger than 64GB or if you do this mod.

Usually a phone manufacturer will list as the maximum, whatever the highest capacity on the market was at the time the phone was released. I guess this is due to concerns about false advertising accusations, since consumers might not realize that the phone's maximum SD capacity is much larger than the capacity of SD cards that can actually be purchased.

I believe 64 GiB and 256 GiB SD cards both follow the SDXC spec; assuming that this is true, they should both work in exactly the same set of phones (except in cases where phones intentionally limit the SD card size in software, or don't follow the spec properly; both of these cases are quite rare).

Of course, it'd be better if someone can test this rather than trust logical intuition, but I'd be very surprised if 64 GiB is actually the maximum.
