[KERNEL] [KEXEC] Kernel EXECution for locked devices [N900V] [WIP]

[ryanbg]

I see. Let me know if you'd like to contribute to this thread. I'll update it soon with more details about the required patches & the preliminary results of my tests ––after releasing a new version of JasmineROM.

Absolutely. The more minds we have on this the merrier. Anything I can do to help.

I was told by a defy dev that we would have better luck contacting hp touch pad kernel devs. I guess their kernel is more like ours I guess. Idk. I never tried contacting dev from their yet

I've taken a peak at quite a few different variants used. The Z1 has a similar chipset and I've been basing most of my work off of that so far. Appreciate the info.

Good luck guys! [emoji106]

Note 3 ?

The effort is greatly appreciated.
Will never buy another phone with locked bootloader.

Update [08/01/2014]:

I've successfully flashed a custom kernel on my device. This trips knox counter & isn't 100% related to kexec, but it has the same objective (loading custom kernel on the locked-bootloader devices). However, the bootloader makes security check & blocks the installed kernel with the "unauthorized software by VZW" warning. Then, I tried to patch the kernel to remove this security check, but my device was HARD BRICKED. Now, I've created a General thread for how to recover from a HARD BRICK. This is definitely a very promising info for testing bootloader exploits.

Holy sh*t hsbadr you are a God. You jumped in so late posting up amazing content stupid fast and now your close to unlocking custom kernels?! It's simply mind blowing. I wish I had half your expertise. I envy you bro.

I for one could give a crap less about tripping Knox.

I'm confident that everyone here feels the same, BIG thanks to all that you have done for us Verizon note 3 owners. You might just make this the hottest phone available.

Thanks!

I for one could give a crap less about tripping Knox. What's the goal to reach from this point? Get custom kernels and not trip Knox? Is that what kexec achieves?

This is JFYI; some users care & I myself have just happily tripped mine for testing more important things, even if it's NOT 100% achievable. I like to use the device I bought as I wish cuz it'll be useless with time if I don't. Then, we trash devices & upgrade to a new one. So, USE YOUR DEVICE NOW BEFORE IT BECOMES TOO OLD !

I'm confident that everyone here feels the same, BIG thanks to all that you have done for us Verizon note 3 owners. You might just make this the hottest phone available.

You're welcome! Glad I could help.

A lot of people care about tripping knox. I'm 50/50 on it. Cause every time I've RMAd a phone, they send me a new phone first, then ask to return the old phone.

Most of the time, hardware fails are not a result of flashing custom software onto the phone anyway.I doubt they will bicker about it most of the time. But who knows. I don't work in the remanufacturing department

I'm getting excited about kexec!

Had anyone read this http://www.droid-life.com/2014/08/07/moto-x-bootloader-unlock-qualcomm/
says the note 3 could also be vulnerable

He said on twitter yesterday that LG and Samsung devices can't be unlocked via TZ.

But maybe it can just need more info or other devs to pitch in

 

[ryanbg]

Might I recommend possibly using the MJ7 bootloader if you are still on the NC2 bootloader and can downgrade. In that MJ7 boot image, I'd recommend using modified the dt.img and tags address and setting it to write over the aboot signature check..

I thought you can only downgrade to MJE!?? Am I wrong?

 

[mjh68]

I thought you can only downgrade to MJE!?? Am I wrong?

I thought so as well, can only go back to MJE as full tar. Can flash any modem though.

If you haven't flashed the NC4 OTA, or still have the NC2 bootloader, you may fully downgrade to MJ7.
