[ROM] OUKITEL U7 PLUS - STOCK ROMS & TWRP

[Hazuki]

Ok, I will do that, can you upload somewhere the drivers that you have installed in your computer for this phone to use them instead of the drivers that I have found on the internet. It's the only thing that I haven't tried.

Install the next driver on your Windows 7 Ultimate :

Then, flash the stock firmware with the next version of SP Flash Tool :

Ok I have reflashed with firmware upgrade now, I didn't use the drivers that you have uploaded because I have already the latest. Windows said that there is newer version installed in my system, so I used those.

Now, the flash completed succesfully (like the all the rest that I have done). I powered the device, I saw the oukitel log and animation but it froze after the animation showing the logo. It rebooted several times always showing the oukitel logo only and not playing the animation. After five minutes it rebooted again it shows up the oukitel logo and start the animated logo also but freezes without completing the animation. I think it is dead, I give up, if you have a stock and signed rom to flash it would be the last thing that I can try.
Also if I use the following will be able to boot my device avoiding the bootloader, unlocking oem?

fastboot boot boot.img

Tried, doesn't work with locked device.

@Hazuki :

I do not know what to tell you.
I have had NO problem to flash the Nougat stock firmware.

I have flashed it with success (Firmware Upgrade) on Linux OS ... look :



I have flashed it with success (Firmware Upgrade) on Windows OS ... look :



I have done a downgrade with success from Nougat to Marshmallow ... look :



Many people have had serious problems to flash it.
Why do NOT I have any problem to flash it ?
Can somebody please explain to me why do NOT I have any problem ?


Please, do me the next big favor :

Flash the Marshmallow firmware and never update your U7 Plus to Nougat.

I am exhausted

Well I don't blame you just Oukitel for releasing a firmware without testing.
For the heck of it I flashed the twrp for the nougat firmware that you suggested.
It installs fine and I can boot to it, I even installed the supersu and the busybox packages. Also no errors during the installation of those packages.

Rebooted the device, left it for three hours on but again nothing.

When booting to twrp asks for a password to mount /data partition. What is this password needed for or do you know?

I will try to erase the data and cache partition just in case that might fix the bootloop issue. Any ideas are welcomed. Also which mode in sp flash tool do I use to downgrade from nougat?

Can you make a backup of your rom with enabled the usb debugging and oem unlock plus root and twrp using sp flash tool and to try flash this image to my phone. This would be very helpfull thank you for your time.

@Hazuki :

Do not blame the Oukitel for your issue to flash the firmware.
I am able to flash the stock firmware.
I showed you with my screenshots.

Please download the V20 Marshmallow stock firmware :

And flash it with SP Flash Tool (Firmware Upgrade option).

Your Windows OS version ? (seven, eight or ten).
Do you have disabled driver signature enforcement ?
Do you have installed the VCOM driver ?
