MT6571 Nand Write Flash.

MT6571 Nand Write Flash.

Hi there.

I have a Swipe konnect 4E V2 phone.

It was hanging a lot, So i tried formatting it with Cm2.

I Readed the Flash from it and formatted it.

Now after format it got stuck on startup. So i tried to search for its factory firmware and found out that there was no similar version available anywhere.

As i had a backup with Cm2 i tried restoring it and i get the following.

Quote:

Unsupported Yet( or bad ) file selected!

Now i had no other options so i tried flashing the phone with other available firmware.

After flashing other version now The phone is Dead

And the info in Cm2 after flash is the following.

By inspecting the above log i can see that the preloader is erased due to wrong firmware.

Now im stuck in a weird situation. I dont have original firmware for this phone. But i have a readed backup, But writing Nand is still not supported.

I even tried Flashing the backup with Sp flash tool but the phone only makes MTK usb port.

Is there any way out of this mess ?

Thanks.
