Custom Kernel for MT6739 Smartwatches

It sounds reasonable, because one of the cameras functions correctly. It probably uses the right driver.

143

Please try if this prebuilt fixes the issue: Prime.zip

I tried it, it works very well. Thank you for your time. How did you fix it?

It mimics the flawed behaviour of the original kernel now, i reverted a patch that was supposed to fix camera detection and added the GC5035 sensor driver.

Wow, that sounds complicated. Thank you very much again!

I noticed the same issue on my optimus pro as well.

Photo taken with the ā€˜correctā€™ driver:

Included kernel camera driver:

gc5025_mipi_raw

Logcat:

CAM_CUS_MSDK GetCameraCalData(MainSensorIdx=5025) Enter

Photo taken with the ā€˜wrongā€™ driver:

Included kernel camera driver:

sp250a_mipi_raw gc5025_mipi_raw gc2385mipi_raw

Logcat:

CAM_CUS_MSDK GetCameraCalData(MainSensorIdx=2385) Enter

Yeah unfortunately they donā€™t invest much time in ā€œcleaning upā€
As you have found :grin:

I got it working with the correct driver now.
Have to say that iā€™m pretty happy so far with the Optimus Pro, the camera quality seems decent as well.

Hello none, very good job but i have message error when i flash the OTA.2.5B

For an OTA update you need to revert back to the default boot.img as the recovery does a integrity check.

Hi there,
please, may you so kind to confirm me if this good job is suitable for use on LEMT, aka TiCWRISā€¦?
Thanks a lot in advance

@none
I donā€™t know if you have included all the drivers needed but right now @JuliĆ”n_Chico the answer is no.

Indeed, there are currently three mainboards that are based on the MT6739 made by the OEM Wiite.
(Please note this is just a rough summary and not a complete list).

C7S (round):

  • Kospet Prime (SE), Kospet Hope, Lemfo LEM8, Lemfo LEM X, Lemfo LEM12, Kronosblade Genesis, Rollme S08, Zeblaze Thor 5 Pro.

C8 (round):

  • Kospet Optimus (Pro), Makibes M3, Lemfo LEM9, Zeblaze Thor 5.

C10 (square):

  • Lemfo LEM9, Lemfo LEM T, TICWRIS MAX.

From those, i currently own the Kospet Optimus Pro and Lemfo LEM12.
I can only test and support devices that are very similar.

If OEM Wiite is the Mainboard manufacturer, it is like the main manufacturer behind all this full android watch thing. Does Wiite have a website? What is ā€œAlpsā€ by the way? It pops up in the apps displaying the smart watch info. I am very curious, who is really behind all this manufacturing. The android smart watches are so smilar that I start to believe that they are really manufactured even at the same plant:-)

Yes, as far as i can tell.
Their website is: http://www.wiiteer.com here is the C7 mainboard for example.

ALPS is associated with Mediatek, iā€™m not exactly sure what they are, the only source i could find says:

Alps is the motherboard solution developed by MediaTek General Outsourcing

Basically it breaks down like this - wiitee is the solution provider.
They make the PCBA and firmware for all the Full Android devices (apart from a few)

The rest of the watch is designed and built around this pcba by several factories.
The factories have customers like Kopset and Lemfo etc etc ā€¦

I have been working with wiitee for 5 years now as a consulting partner - which is why I have direct contact with them and access to all the firmware and so onā€¦
Thatā€™s why they are in my avatar photo from my last visit to their office in Shenzhen.
The owner and manager is on the right in the photo and on the left is the senior engineer.

I talk to them almost every day about various issues and developments .

After the holidays I will open a development section here.
We are hoping that members may be interested in a development reward scheme.
Weā€™ll see how that goes.

Now, the puzzle in understanding the similarities is almost being solved. :slight_smile: If Kospet Prime is designed by Kospet, how come the same watch is also sold under the name Allcall Awatch GT? They are exactly the same. Is Kospet giving the not sold extra watches to Allcall with a good price? Or the watch is fully manufactured in a third party and the third party has an agreement with Kospet to produce and sell the product to others? Too many questions, I know. There is a video in YouTube demostrating the Lemfo factory, it seems like they are assembling parts over there.

Ok, thatā€™s simple.
The factory that made the Prime and the Optimus is KingWear.

KingWear can then sell these models to whoever they want.
The KC10 (Kospet Prime) is sold by various brands.

This happens with other factories too like Ledai who make the Lemfo LEM 12 which also sold by other brandsā€¦

There are basically 3 or 4 factories now and they are responsible for producing all the watches but they donā€™t generally sell their products at any less than 500 - 1000 pieces at a time.

Thatā€™s where the e-commerce brands come in, like Lemfo, Zeblaze, Kospet and othersā€¦

Thatā€™s it reallyā€¦

Solution provider,
Factory
Brandā€¦

In that orderā€¦
