@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 😃

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.

Yurim, I'll try my best to get it done the next weeks. Currently time is a rare factor...
As far as I know, the device of Mik-el is working now (more or less). So it might be a good idea to let him try this method himself.

Found the time today and tried the method via fastboot. Sadly to say, it doesn't change anything. Phone keeps bootlooping.

@io2345 @giotogo
I'm chatting with @blacklisted.rock on telegram. He said he'll send me a better porting guide.
Me and @YuriRM have already chosen a new and better rom to use as port rom.
The failed installation/ updater-binary errors were already solved in my last viperOS port.
Hopefully this time we'll get a booting Android 7 rom.
Regards

Hi everyone, I am also the owner of takee1.
I haven't used it for a long time, but when I saw that someone was doing something to bring it back to life, it gave me hope.
I would be interested in updating it with a more current rom, since 4.2 is no longer compatible with anything!
I hope it will be possible soon.
These Chinese continually churn out new models, but never firmware updates!....shamefull!

Arrow June 2020 Updates: Rom ported! Now we need a recovery!
June 2020 Updates: Rom ported! Now we need a recovery!

Guys, I've really faced a lot of problems when trying to port this rom:
1) I had to wait 5 months to receive a working battery from China, thank you Corona Virus...
2) university... XD
3) porting guides on the web suck, I had to contact many people and study many articles and video guides... until I had to make my own porting guide...
4) some tools to extract boot.img files extract .img files, but with a wrong structure!! (and I discovered this just recently!)
5) I had to change the port rom, now I'm not using a ViperOS rom, but a RidonOS rom from a Micromax device much more similar to Takee 1 (more than 90%of the hardware is identical)
6) I want to thank you @io2345 for helping me to test over 10 roms!! We had to exchange almost 100 mails to bring you a new and updated Rom!!

Anyway after all this FREE effort I think that I finally got a working Rom !! (correctly ported!!)
But we dhave another problem now...
We discovered that the custom recovery we use on Takee 1 (twrp 2.8.0.0. developed by @luckasfb ) is too old to support Android 7! We need a new custom recovery, probably a twrp 3.0 or above.

I've already researched new material and guides on the web. I found a guide that seems to clearly explain how to port a custom recovery to any device.
The process is simple, it consist in the extraction of the recovery from an Android kitchen in Linux, the rest is about replacing files.

Is this the end, or not?
Anyway the process is long and boring...
I'm quite busy with exams, life a few other projects...
I don't know if continuing this project is convenient for me at this point...
If someone wants to help me and @io2345 please leave a message hereunder, I'll leave you links and infos about the recovery porting.

Cheers!
