[Q] Miracast installation how-to (Project from Kensuke) - Nexus 7 Q&A, Help & Troubleshooting

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

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!!

Phone not booting after attempt to update 4.4

So I got the OTA update to 4.4 on my Nexus 4 4.3. I clicked it and it rebooted, took a few minutes to run some files via dos prompt...Afterwards I ended up at my TWRP screen. I selected "reboot" at the main screen then "system" thinking that the stuff happening at the beginning was the install update to 4.4. Afterwards my phone is no longer booting, like it has no OS. Hindsight, I think I should have done some research before continuing. Need some help? What are my options? Download fresh 4.4 and reinstall or ?

Transfer zip to a pc Open up the zip file with winrar or 7zip there is a meta inf folder find the updater script file open with notepad erase the first line it will say something like asset get prop ect...... save the file transfer back to tablet it will now flash. Or use cwm to flash. I can do it for you if u send me the updater script file.
Even I have the same problem and if you flash a modded zip, TWRP and CWM give an error with no specified status number. I even tried signing the zip
EDIT: Install CWM and toggle signature verification. Simple right?
Press thanks if I helped.?

Thanks for the help. Unfortunately I got a tad frustrated and accidentally deleted EVERYTHING!!! So I have blank tablet now. I'm trying to download the Google Factory Images from their site but it only downloads this .tgz file instead of a zip with 4 files. I even tried extracting the .tgz and it give me a single file. Anyone have any ideas as to why this is?
I'm trying to restore this tablet based on following this page (can't post outside links on this site until after 10 posts?.......really?)
But as you can imagine I'm stuck because I can't download the aforementioned zip file.
My tablet is soon becoming destined to be a rifle target.
BAM!!! Never mind got it all squared away. Now if we can get that ROM set up so that it will work properly.

I used CWM to load the ROM no problem. Thanks for the heads up.
So far I''m loving this PACMan ROM, smooth and tons of options. For me KitKat ruined my tablet, completely breaking the auto-rotate (making is stick in portrait mode), chrome crashed all the time and it was just generally laggy and slow.
Thanks to all that replied.

Kitkat should work with no issues. i use slimkat 4.4.2 and i love it. Just make sure you wipe before the kitkat install and your tablet will fly.

[Q] I9505G OTA Upgrade Fails

I rooted my I9505G running 4.4.2 bit did not replace the boot loader or the ROM. I just installed Supet-SU.
I've had two 4.4.3 OTA downloads but they fail an assert for build.prop. I've checked \system\build.prop and it if unaltered and contains the string the assert is linking for.
Do I need to unroot before upgrading? I just assumed that I would have to reroot after upgrading. I didn't expect a fail as I haven't altered the boot loader.
Yes you'll need to flash original FireWire with Odin but before proceeding with the flash run triangle away it should be ok then

FireWire? What's that? I don't think I flashed anything like that.

That page has some problems. Power+VolUp is needed to boot into recovery, not Power+VolDown. I can get into recovery and select install from external memory. I copied the update onto my sdcard but it still fails with the same assert fail

assert failed: get.prop("ro.product.device")== "jgedlte" || [...]
checking \system\build.prop I see the line

It's not my problem if you don't know read.
I followed Method 2. I see what you're saying now.
None of these upgrade methods worked. I still had assert failures. I removed SuperSU after restoring all changes I made to /etc.
Somehow this morning the phone failed to connect to data services. Several apps failed when they tried to access the network.
I eventually reflashed a 4.4.3 rooted image from here http://forum.xda-developers.com/showthread.php?t=2772043 and restored my Titanium Backup.
OTA upgrade to 4.4.4 succeeded after turning of SuperSU and reverting my change to \etc\permissions

Error executing updater binary in zip (TWRP)

I'm getting this error when trying to flash lollipop roms. I can flash Kitkat roms fine as I'm currently running xdabbeb VS982.5 1.0.0 (G3 rom), but it won't let me flash any lollipop rom. I installed twrp via the autorec program which installs 2.7.0.0 then I updated twrp within twrp with the flashable zip.
Please help
Thank you
Anyone?
Seriously no one knows? What is everyone else using that is flashing the latest 5.0.2 roms?
What am I getting this error?
Please help
Possible Fix
I've also had this problem. The only way I can seem to fix it is to also download the .md5 along with the rom itself. Just make sure its in the same folder as the rom. Everytime I have that problem with TWRP this seems to fix it. Let me know if it works for you!
Edit: Also I forgot to mention, if one isn't available to download I can help with that.
Thanks for the suggestion. I'll give it a try. If there is no. Md5 what do I do then?
All you need to do if it comes to that is download an md5 checker on your computer. Just curious, what rom are you trying to flash?
I tried resurrection remix and liquid lollipop roms. I had no issues with the initial 5.0 lollipop roms so I'm not sure what changed with 5.0.2.
So the md5 checker generates the .Md5 then you just put that on the SD card with the rom?
Resurrection remix should have an md5 on the download page right below the rom itself.

Can you point me to the program to use on my computer? Do I just load the .zip file in the program to generate the .md5sum file then put both the zip and the .md5sum file on the sdcard before flashing?
Thanks

Nope, I downloaded the md5 file along with the zip and I'm still getting the same "error executing updater binary in zip".
Any other suggestion? How is no one else having this same issue? I'm using the latest version of TWRP 2.8.3.1 probably like most people. I don't understand.

Try to reflash the TWRP.. or maybe is something wrong with the zip file
Use the TWRP compiled by blastagator
Nope, still getting same error with latest twrp.
Finally got it working. I downgraded TWRP to 2.7.0.0 and the lollipop roms are flashing fine now.

@[email protected] i think kk aosp room need jb bootleader
Hello everyone,
I am running a D802 on stock Lollipop and installed TWRP 2.8.6.0 via AutoRec. Now I booted into recovery, wiped System and Cache and got the Error message when installing CrDroid (Marshmallow 6.0.1). Now I tried installing TWRP 3.0.2.0, which succeeded and then downloaded the twrp 2.7.0.0 zip to try that as the ROM still wouldnt install. But it wont install the older TWRP. So I am asking for help to either
1) Install TWRP 2.7.0.0
or
2) Delete the getprop lines from updater-script (after I removed them I get an error 6 so i probably removed too much?)
Thank you in advance
(Guide for Error 7: http://forum.xda-developers.com/showthread.php?t=2522762)
EDIT: Someone said installing another Kernel might allow installation of the ROMs. Which Kernel could work for my phone?
EDIT 2: When flashing TWRP 2.7.0.0 it says "assert failed: run_program("/tmp/loki.sh")==0". So what exactly am I missing on my phone? Is Loki the MM Bootloader?
EDIT 3: Could it be that the build.prop was deleted when I wiped system? Would be weird if that was the cause, but I simply dont know..
Edit: Booted in Downloa Mode and flashed v30D KDZ with the 2014 LG Flashtool. Works with Stock ROM for now
