Kernel Flasher

[benwaffle]

This app allows you to use safestrap on certain devices running 4.4.4 and 5.0.

It basically runs

dd if=kernel.img of=/dev/block/platform/msm_sdcc.1/by-name/boot

I am not responsible for anything that may happen to your device.
Post stack trace/logcat in this thread if it crashes.
If you get errors when updating, uninstall first.

AT&T Note 3 - NC2: this post
AT&T Galaxy S 4 - NC1
AT&T Galaxy S 5 - NCE

If you want to modify for your device, you can edit strings.xml

What exactly does this do?

 

[benwaffle]

Flash the NC2 kernel image without Odin (to access SS). To get back to nj5 or nl1 you still need odin or a flashable zip.

 

[kizzle4]

Is there a flashable zip for us? And does that work via safe strap , flashing a kernel?

 

[corybucher]

Installed this but it force closes everyone I open it

Everytime*

 

[benwaffle]

Can you give me a stack trace? Via 'adb logcat' or if there's a report button, there should be a stack trace section at the very bottom

 

[corybucher]

Never mind it worked somehow

 

[benwaffle]

If safestrap doesn't allow you to flash kernels then this is an even worse idea. Use at your own risk.

 

[kizzle4]

Almost certain it doesn't but mostly just because we've always been stuck with one and never had this kind of option.. But I'm pretty sure we can't flash any non signed kernels with our locked boot loader.

Not safestrap it's bootloader preventing kernel lnstall

no, it's the bootloader preventing custom kernels from actually booting
i can flash them though

we can flash modems with safestrap this. is your app? It would have been nice to have this to boot safestrap, and safestrap to install NJ5 kernel, then we would not need a computer all the time.

I will try and see if adb will install a kernel, if it fails then I would sat the bootloader is blocking any kernel

I can make the app reboot to safestrap on flashing if you tell me how.

@benwaffle you were absolutely right bootloader did not stop kernel install

putting nc2boot.img on internal sdcard then using adb

adb shell
su

dd if=/sdcard/nc2boot.img of=/dev/block/mmcblk0p14

reboot

it installed ns2 kernel and it booted to safestrap

here is the cmd windows readings

your NC2Flasher.apk does FC and then Supersu popped so app has root

rebooted phone and app still FC

let me know what I can do to help

obviously `dd` works, that's what my app does
can you give me a stack trace?

 

[carl1961]

ok how do I grab that "stack trace?"

here is log cat

Got a idea. When you get your app to work I want to try and put nc2 on slot 1 run slot 1 which is nc2 to use your app to install nh1 kernel then hopefully it boots stock slot. If that works then we have a way to do things without odin. I already know that nc2 runs fine on Nl1 firmware except for kernel.


All attempts to install kernel from NC2 running on safestrap failed, and installing NH1 4.4.4 kernel with odin did not ignore safestrap being on slot1, so I had to use safestrap to set phone on stock slot to boot 4.4.4 rom

so even if you did a app to install NH1 successfully ,being in slot1 won't allow 4.4.4 rom to boot

@benwaffle

Awesome app. Thank you so much for creating it for us. One of my biggest problems with 4.4.4 was having to be tied to a computer for anything i wanted to flash. This has made life so much better.

One suggestion I would have is...I wonder if it would be possible to have your reboot method automatically boot into SS instead of having to choose it. I know that @RErick had created an option for the ATTNote 3 that when reboot to recovery was chosen from the Power Options that it automatically went to SS. Maybe you and he can get that together.

 

[TheDriller]

I'll be working on that with my update

 

[benwaffle]

Should be trivial
