PMP5580 rom porting to NX008HD8G_WM

[skyhi]

Hi Shaun,

Can you recommend a good tool for modifying the boot.img file? The ones I've tried seem to error out for this tablet.
I've tried android rom kitchen and others and they seem to have problems because these are not 'standard android' images.

Btw - the 'stock' boot.img file seems to launch the Cyanogen roms but it hangs at the loading image.

Thank you!

Look for CXZ's boot image tools in the Ainol forums at Slatedroid.

Cyanogen based ROM's hang with the stock boot image because the init.rc file in the boot image requires changes to support Cyanogenmod.

You can download the tools to unpack the boot.img and the tools to sign the image after here. http://www.mediafire.com/download/d4...1hrz/tools.zip Unpack the boot.img from the NXM8000NBD_WMN and cm-11.0. Don't close the command window on the NXM8000NBD_WMN yet. Delete the init file and all the *.rc files from the NXM8000NBD_WMN initramfs folder, then copy and paste the init file and the *.rc files from the cm-11.0 initramfs folder and pack the new boot.img. Rename the boot.img.new to boot.img, open the cm-11.0-Next8HD8G_WM-boot.img-*.zip and copy your new boot.img into it over writing the Next8HD8G_WM boot.img. Then you have to sign the cm-11.0-Next8HD8G_WM-boot.img-*.zip before flashing it.

Download the cm-11.0-Next8HD8G_WM-*.zip http://www.mediafire.com/download/kb...M-20140308.zip and open it in 7zip. You are going to need to copy some files from the NXM8000NBD_WMN rom so open it in 7zip also. From system/lib copy libMali.so and libUMP.so, system/lib/egl copy libEGL_mali.so, libGLESv1_CM_mali.so, and libGLESv2_mali.so from the WMN rom to the cm-11.0 rom. Close the zips and sign the cm-11.0-Next8HD8G_WM-*.zip before flashing. If you need more help just ask. I switched out the proprietary files in the roms with the ones from the nextbook so guess it's not a compatibility zip.

You will probably need sensors.amlogic.so and possibly some idc files also.

A senior moment.

Forgot about sensors.amlogic.so. Also you need set_display_mode.sh in system/bin. Plus there is cpufreq_ondemand.ko, dhd.ko and about sixteen other modules to modify if you want to load them. They have to be modified to match the kernel, lot's of fun with a hex editor. I should go back and see if I can get cm-11.0 to boot with the Next8HD8G_WM kernel, last attempt ended with a bootloop.

How did we both forget to mention set_display_mode.sh???

All of the one's I tried, booted with the stock kernel, but I can't remember if I tried CM11 or not...

Honestly, I haven't done much with it lately... Got frustrated because I couldn't get everything working correctly, still having problems both internal and external storage, wifi and audio.

Been focusing on getting CWM, unbrick kits and modified stock based ROMs out for more models instead.

Yeah, I think the is a volume limiter in Cyanogenmod, but these tablets had crappy speakers to begin with...

I had the stock kernel booting but when the modules are loaded it bootloops. Think I'll just forget about using CT's modules and change the governors in the init.rc back to what nextbook used. Time to forget about the PMP5580C port and work on one of my own. Should be easy to get NXM8000ND_WMN tablets working also.

This would be a good thing. I will have it installed quicker than you can say a very long 5.5 minute sentence

I got a chance to install your most recent CM11 port and everything seems to working acceptably (although this is the first time I've had the rotation artifacts appear). Even audio has an acceptable level for this tablet's tiny speaker.

Did you have anything specific I should test while I have it installed? Aside from the rotation issue, it seems to be working as well as the 10.1 version.
