[ROM] [7.1.2] Mik-el Android for Takee 1

Ignore this post (Previous and failed porting attempt)

First Porting Attempts and Bootloops (Novemeber 2019)

After many Roms that refused to install, I finally got a Rom that can install, and that almost booted (damned bootloop!).
Maybe someone that has experience can quickly spot my error;

Base Rom used:
A Custom Rom, Android 4.4 Kitkat + 3.4.67 Kernel

(Download here )

Port Rom used:
Android 7.1.2 Rom with 3.4.67 Kernel. (ViperOS )

(Download here)

Porting Guide used:
Nougat Porting Guide For MTK 6592 KK Kernel 3.4.67

+ mount points adjustments made by me

Check My Ported Rom:
If you have experience with Android portings you can help me, giving a look to the Rom here.

Don't install this Rom if you're not a developer Otherwise you'll only get an unfinished Rom.

Updater-Script file of my ported rom
Initially the Rom didn't install at all for some stupid syntax error in the updater-script file. Now it's fixed.
Read it on Pastebin

Other Infos
--- A cache unmount from TWRP is required to install the Rom (I don't know why but it's not a problem!)
--- During the boot(loop) the screen is distorted (maybe it's the classic horizontal-vertical problems of custom roms, we can quickly solve it after the first effective boot)

Thanks! This ROM will bring a fresh air and new lease of life to EStar TAKEE 1, the first ever Holographic 3D smartphone launched in 2015 at an affordable price ($100-150). Nobody will need to buy an extremely expensive RED Hydrogen One at $1200.
The 3D community will rejoice!

The amazing resources of PHEREO are available to all lovers of 3D Stereo Images and Photos.

Select an image and click Wiggle... if you do not have a smartphone with 3D display.

My advice is to install the PhereoRoll3D app too!

NewPipe - to download 3D videos from YouTube

INVIDIOUS - to download 3D videos from YouTube, VEVO, etc.

Plenty of resources for 3D lovers that justify buying a device with 3D display.

interesting. this phone is still good.....

Anyone with ViperOS development experience?

More than ViperOS developers we need someone that has experience with rom porting.
I made more than 7 releases for this ROM and @io2345 tested them all!
We solved the failed installation problem, now we just need to solve the bootloop.
The porting process is OK, the updater-script file is OK, file permissions are OK...
I don't know where the problem could be!

Next time I'll use another porting guide. (there are only 2 guides and one didn't work since now)
Instead of ViperOS I'll also use a LineageOS rom as port rom.
Let's see what I can get.

(Stay tuned subscribing to this thread and collaborating with us, cheers)

My suggestion is to try other 3.4.67 ports for EStar Takee 1.

Have you acquired knowledge enough for including specific drivers of EStar Takee 1 into this Android 4.4.2 KitKat kernel of BQ Aquaris E5 FHD?

You will get a much better kernel (3.4.67) than luckasfb.

I hope there is a solution for camera bugs introduced by luckasfb in his latest kernel of EStar Takee 1.
Some KitKat kernels share both cameras (Sony imx135_mipi_raw and OmniVision ov5645_mipi_yuv) with EStar Takee 1.
However, it may be down to GPIO pin numbers in the Circuit Board. That is why I want to know the Circuit Board ID number, the physical address number of each component and GPIO pin numbers of camera sensors of those devices.
That info is included in the kernel source code of BQ Aquaris E5 FHD.

@giotogo can you find this information inside your EStar Takee 1 device, please?
Circuit Board ID number
GPIO pin numbers of camera sensors in the Circuit Board
Take detailed photos of internal components
Take detailed photos of internal numbers printed in the motherboard.

This information may help find other devices that share an identical Circuit Board ID number. This list of most compatible devices is useful. Hopefully, It will enable to choose the easiest Android 7.1.2 Nougat ROM to port into EStar Takee 1.

It also provides crucial information for changing the GPIO pin numbers of both cameras in the KitKat kernel source code of EStar Takee 1.

The video below shows how to open a device and find the Circuit Board ID number.

However, my guess is that it boils down to the physical address number of each component and GPIO pin numbers in the motherboard. This enables to direct each camera driver (front and back cameras) to a specific address in the Circuit Board (GPIO pin number). This is the info that luckasfb tried so hard to find, trying by hand hundreds of combinations for GPIO pins. He did not open the case of his EStar Takee 1 device.

@io2345 how are you doing? It has been a long time since we last talked.
I may have found a solution for the bootloop of the Viper ROM ported by @Mik-el.
Can you test this method, please?

Have you watched this video by the clever german guy, Christoph Zahradnik ?
His Viper ROM is used in this explanation... Viper SC2_5.2.1.zip 😃
