Root for Note Air 2? - Page 6

Renate · 03-05-2022, 02:58 PM

Yeah, what you're showing me in UsbView is the normal mode of MTP/ADB.
We're only interested in th QUSB_BULK, but I can see that's working.
Just start fresh and fix the /llauncher.bin

I tried this with two "ll" at the beginning even though the filename is launcher.bin:

Ok, the way that it knows how much to load is from loading the ELF header. Are you sure that you have a good ELF file there (launcher.bin)? Use a hex editor and look for <7f>ELF as the first 4 characters.

Code:

elfview sdm636.bin /p
 #  Type     Flags     Size  Offset  Address
--  -------  -----  -------  ------  --------
 0  null                792  000000  00000000
 1  null               6856  001000  85e28000
 2  load     RX      356508  003000  14015000

 9  load     RWX     100568  06F730  14098000
10  load     RWZ          0  088010  146b2000
11  load     RWZ          0  088010  14680000
12  load     RX       77248  088010  14699000

(Sorry that's my own tool there. I don't know what else can show it.)

Here's the file. I didn't find any mention of <7f>ELF in there.
launcher.bin

Renate · 03-05-2022, 03:27 PM

That's garbage. It's all HTML. Somebody copied a web page instead of the destination of a link or something.

Try this:

https://github.com/bkerler/Loaders/r...4665_FHPRG.bin

I checked it, it's 660,620 big and it is an ELF.

That's the loader Cascade94 posted for the Note Air 2 here

Unless the filename is the issue. I copied the launcher file over again from github and tired again:

No, the issue is the file you posted is not a valid file.
Do you have a file that's 660,620 big now?

Yeah, I copied that one over again and tried again. Result is the error message from my previous comment.

Renate · 03-05-2022, 03:51 PM

You keep trying to load "auncher.bin".
You have to do a full reset when you mess up.

If the loader doesn't load don't bother trying things that need the loader.

There is a bug report already here (for the bin) https://github.com/bkerler/edl/issues/200

I've tried again and now I get a different error, but it seems to have worked at least half way.

No Firehose detected, wrong loader?

Renate · 03-05-2022, 04:31 PM

Well, that's what I would expect. A generally valid loader, but not the one that will make this work.

Somebody mentions a patched loader in the last msg of the github link. I looked for it but got bored by websites with a dozen "Download" buttons.

Try to find the one they mention. Start fresh every time you fail. The Qcom protocol (Sahara) itself is the problem, it's so stupid and fragile.

Ok that helped. I now have no errors:

Sending prog_firehose_life_ddr_patched.elf................ .................................................. .................................................. .................................................. .. Ok
Firehose detected

but now what? It didn't give a file or anything.

Just for fun I also tried:

C:\Users\David\edl>edl.exe /u text 0 10
Found EDL 9008
Wrote config... Ok
Wrote request... Ok
Receiving text.. Ok

On my Mac I tried

Code:

python3 edl printgpt --loader=prog_firehose_life_ddr_patched.elf --memory=ufs

and got this (lot's of output):

Renate · 03-05-2022, 05:43 PM

You did get a file. Didn't you notice that you have one called "text".

So, it all works, now you just have to get the boot image.

Start fresh.

Code:

edl.exe /lprog_firehose_life_ddr_patched.elf /u boot.img 65414

(Copy this carefully.)

This should produce a file called boot.img somewhere around 15-20 megs.
Does it?

Ok, this just pulls the boot.img off the device and does NOT write anything on the device. That's what I understood from the tool. Better to be safe than sorry

Renate · 03-05-2022, 06:02 PM

It does not alter anything on the device.
Did you do it?
