Hi,

The project this question is about:

Miracast on "Older" Device:
(Project can be found here: [nourl]https://github.com/kensuke/How-to-Miracast-on-AOSP/wiki[/nourl])
I'm very thankful for the work of Kensuke and his project to bring Miracast to the Nexus 7 2012 Model. I've been constantly watching it and finally its out for 4.4.2!

My problem is:

I unlocked + rooted my Nexus 7 via the Nexus Root Toolkit 1.8.0 with my current Android 4.3 Jelly Bean. I installed the "Team Win Recovery Project" but now I'm stuck on how to proceed to get the ROM from Kensuke.
Do I have to install 4.4.2 stock first or can I somehow install directly the .zip File for the "grouper" Wifi Nexus 7. A few instructions or a guide on how to install from 4.3 to 4.4.2 miracast rom would be awesome

I'm relatively new to the whole rooting scene so please be patient with me
Any help is very much appreciated!



Best regards

Halcyon

Not really an error.
I just need to know how to get from rooted stock 4.3 with TWRP to 4.4.2 miracast ROM from you.

Do I have to install 4.4.2 stock first or can I just straight go to 4.4.2 miracast from your ROM?
And how can I install your rom? I put it on my device and then?
Looking for kind of a short/quick guide.

Thanks for replying so quickly and your great work, kensuke

OK
my device N7 2012 3G "tilapia" example. if your device is grouper, substitute tilapia/grouper .

Files
1) stock 4.3 - nakasig-jwr66y-factory-bdbb7bd7.tgz
2) recovery - openrecovery-twrp-2.6.3.1-tilapia.img
3) 4.4 ROM - 20131222_mira01_aosp442r1_tilapia-ota-eng.zip

latest Miracast ROM links
http://forum.xda-developers.com/show....php?t=2515833


How to flash 4.3 to 4.4
1) put 4.4 ROM on sdcard
Quote:

$ adb push 20131222_mira01_aosp442r1_tilapia-ota-eng.zip /sdcard/

2) goto recovery
Quote:

$ adb reboot recovery

3) recovery operate
wipe Data / Cache / Dalvik, Flash 4.4 ROM, reboot

Only this. Stock 4.3 to Custom 4.4 directly.
If reboot-loop happen, Full Wipe needed.


Warning!
My ROM didn't contain gapps and SuperUser.
Your data should back up before flashing.

I redownloaded the file and checked md5 before, it didn't work because on mac it automatically first extracts your zip file. I downloaded it now without extraction and it worked! Thank you so much for your help.
Installed all google apps after that, worked like a charm!!
