Development of Android 8 ROM

[RobbotCC]

Hey all you Sharp 306sh users!

I love this phone and decided to start a ROM port to Oreo 8.0.0!

To date here's what i got

1. Device tree built
2. ASOP stock rom built successfully

Here's what I need to get done next
1. Access bootloader to flash images
2. Test for vendor blobs needed so I can make the vendor tree (if required)

Your help on this would be greatly appreciated as I am just getting my feet we in this process, this is a great phone and I would love to see it updated.

Please let me know if you are interested in helping with this project!

Edit 8/6/2018: Device tree is on Github,
https://github.com/RobertCC18/sharp-306sh-rom

More to come once kernel is built!

Edit 10/12/2018:

I am uploading the first test build so I can get some help with the debug. THIS ROM IS GETS STUCK AT THE SHARP BOOT LOGO AND IS NOT READY FOR PRODUCTION DEVICES!!!!

That being said, any help and logs that you can send are greatly appreciated.

This zip can be flashed through TWRP, check the downloads section

Great! I´ve got a 306SH model, i can be a tester... waiting for your first zip :highfive:

Awesome.

I tried this exact same thing before, but gave up soon after I couldn't diagnose what stopped my device from booting with my custom ROMs, as I could never find the logs.

It looks like you're making more headway than me, so I'd love to test it, or even just help out.

Keep on going! A GitHub would be great progress.

Update 7-4-18

Update - 7/24/2018

Recompiling Kernel with debug drivers included - current compiled kernel missing RAM Console support

Github repo coming soon!

Great! Always wanted a custom room on this phone. I can test it and try it out too

 

[Rhioun]

Good progress.

Make sure to keep us updated, once you have a GitHub repo, development should speed up.
I'm sure there are a few techies with this phone that would love to contribute to your ROM, myself included.

By the way, you said ASOP instead of AOSP in the original post.

Thanks, whoops on the typo!

Been busy with work but hoping to upload device tree, kernel base and current build, waiting for kernel to finish building with RAM console drivers.

Github Created

Device tree is added, kernel coming soon!

About accessing the bootloader to flash images, I believe we've done this before.

Tewilove, the man behind rooting the 306SH managed to access it, and made a custom one to flash, if I do remember correctly.

Worth a look.

No development in a while. We all hope you're still there.

I visited the Github and just found it to be text files and folders. Could you possibly post the WIP kernel or other vendor blobs on there,
so we have at least a basis to begin work on?

Thanks,

This is an amazing idea. My 306SH is rooted and ready for action.

Yes I am still here and working on this, just haven't had much time lately. I will try to get the kernel and vendor blobs up within the next few days

Been waiting for a custom ROM for this phone. I'm ready to test it

 

[ndasarathy]

Any update on the development of the ROM??????

 

[dzvxo]

Any progress?

Status Update

Any progress?

Hey everyone,

Sorry for the delay in development but I hit a major snag with the kernel build and am still working on overcoming it. The needed defconfig is missing so I found one that should get us close, at the very least it should allow us to see the RAM debug messages on boot failure.

Also, my internet has been to slow to upload the kernel to github but I have an upgrade and should be able to get it uploaded within the next couple days.

Please share any information that you find regarding this phone here on XDA and beyond, any info you can provide will help me get this up and running faster!

 

[dzvxo]

Hey, how's everything going? Any luck?

 

[nima0003]

What's up with it?

 

[RobbotCC]

Hey All,

Sorry for the delayed responses, this phone seems to be a lost cause. But I am not a quitter lol!

I am hopeing to get back into the swing if things here in the next few weeks and will post more updates and files here shortly

Current problems:
No debugging enabled
Kernel needs patched to support Android 6+

 

[dzvxo]

We wish you the best of luck!
