Sero 7 Pro Modifying ROM for ad hoc Wi-Fi

[bardell3600]

I am posting here asking for help, assistance, coaching.

It seems to me that I have all the pieces to properly modify the Sero 7 Pro ROM to accept ad hoc Wi-Fi connections. I've spent several days trying to find a simple step-by-step guide for applying github patches to existing kernels and flashable ROM. I have come to believe that no such simple guide/aid exists because the process itself appears to be complex.

The Nexus 7 CyanogenMod has been successfully modified for ad hoc Wi-Fi. My research indicates that the Sero 7 and the Nexus 7 are similar enough that the same patches should be able to be applied to the Sero 7 ROM. The Nexus 7 and Sero 7 both:

• Use Android Jelly Bean 4.2.X
• Have the same processor, 1.3GHz NVIDIA Tegra 3
• Use the same Wi-Fi Chip, Broadcom BCM4330
• Kernels use the same Driver, Broadcom bcmdhd Version 5.90.195.104

What I have is the kernel source

The full Stock ROM, latest version

Patches applied to Nexus 7 CyanogenMod ROM with detailed discussion
http://www.thinktube.com/android-tech/46-android-wifi-ibss
Briefly summarizing the discussion and code contained in the above Thinktube webpage:

• The Kernel is patched making changes to the bcmdhd Wi-Fi driver
• The ROM is patched making changes
  1. to the wpa_supplicant
  2. a few additions to the Android framework and
  3. some changes to the Settings App

So in concept it seems pretty straightforward. Where I am struggling is the whole github process of applying the patch to the Kernel source. Then compiling the modified Kernel source. And applying the remaining patches to the ROM with the newly modified Kernel.

I need someone willing to work with me on the github piece. Or alternately coach me through that process.

So the resounding lack of response tells me either I've posted on the wrong forum or it is indeed as complex and cumbersome as I suspected.

But I may have figured out how to accomplish it myself. I have NOT figured out the github process. But I do know a little Linux and do run a virtual Ubuntu machine.

So I :
1. manually modified the Broadcom bcmdhd in the kernel source line by line.
2. swapped the wpa_supplicant file in the Sero7 stock ROM with the one from the Nexus 7 CyanogenMod ROM.
3. extracted the needed sero7_defconfig and initramfs.cpio.gz files
4. compiled the modified kernel source code and created a new boot.img
5. inserted the new boot.img to complete the modification of the Stock ROM

And if this all works, I’ll post my fix in a new thread, perhaps “Sero 7 Pro hoc Wi-Fi Fix”

Oh boy! I've been waiting to hear if someone got the ad-hoc going on the Sero 7 Pro. I've posted asking for help doing this too but never seemed to get a working answer. Did you get yours working and if so could you please post the wpa_supplicant file for the Sero? I would sure like to wifi tether to the Sero. It's the only device I have that doesn't see my phone's wifi.

Thanks a bunch!
