Heres is the link to thread http://forum.xda-developers.com/zte-...de-l3-t3203223

I also quote the actiones I've been taking in Stock Rom rooted with KingRoot

Hi, this is my first post. I'm a self-experienced using Android. For year I had no problems with my devices. I had a Motorola G 1st generation who worked fine, but I waste it. Now, I bought ZTE Blade L3. Such as Moto G, Miracast feature is not enable (at least in my stock rom). I want to know if this device is compatible with that technology (read that works in every phone since 4.2.x). This phone has Android KK 4.4.4. Tried to first connect trough WiFi Direct a Miracast Dongle (easycast), but the phone doesn't connect. Then, I tried whith screen cast option, and the same. Finally, I looked forums how to unlock modifying bootloader.ini, just as I had to do Moto G. I added the lines with BuildProp editor after rooting with Kingo Root: persist.sys.wfd.virtual=0 persis.debug.wfd.enable=1 AAAAAND nothing happens :( I need some help, first to know compatibility (wifi drect certification page is down, unfortunately), if there is a ROM that solve this problem (CM maybe?) and if there are other lines that I must add to buildprop. Thank you very much for your asnwers, and sorry for the bad english (I'm from Chile). If you need any further information, please ask!!! :laugh: UPDATE: use #MirrorEnabeler and the message is "Your Rom is lacking the audio_submix file. You must contact your device mantainer and ask them NICELY no imlement it. Please refer to the red part of the original post on XDA-Developers" This going to take long time, so decided to install stock ROM from other country using SP Flash tool, to see if it has the same problem. UPDATE 2: Stock ROM from other country, same problem. Rooted the phone to make changes using KingRoot. Followed instructions from this thread http://forum.xda-developers.com/hard...evice-t2812193 The thread was closed, and will create another thread for dongles (no chromecast) It says, or those STILL having issues, Check /system/lib/hw directory for the file "audio.r_submix.default.so". If it doesn't exist, ask your device maintainer to add audio.r_submix.default to the product_packages in the device.mk file. (You may not know what it means, but they will.) So, Asked my mobile company to do the changes, they said "the manufacter must". Contacted ZTE to do what is being said, and ther is still no answer. Will ask in thread posted after, to see if they can help me. Please let me know if somebody can run Miracasr in his Blade (also did't found another ROM that's not a Stock one)

I´ve trying to contact manufacter to enable the feature, but It is probable that the stock ROM (from my country) is blocking the feature, just for buying an more expensive phone.
There is NO custom Rom yet stable for my rom (MTK device)

PLEASE HELP ME!!!
Regards and SFMBE.
