Bricked VKWorld VK6735 - pichouss - 2016-05-21

Hello all!

I've just bricked my Phone (VKWorld vk6735 with mtk6735m) Crying

I was unsuccessfully trying to install TWRP, then I went into bootloop. So I downloaded the original stock ROM.
I flashed it using SP_Flash_Tool.
But then the phone went dead!

Even if I remove battery, press and hold vol_down, then plug the computer, the serial device appears for 5 seconds then disapears!

I tried to tear down the phone to test some test points for hardware META mode... but nothing worked.

Any clue?

Hi pichouss !

Questions :

1) Where do you have found the stock rom for your phone ?
2) Where do you have found the twrp for your phone ?
3) Do you have installed the ADB driver on your pc/notebook ?
4) What version of SP Flash Tool do you have used ?

Try to use the next version of SP Flash Tool :

Try to flash the next stock rom for VKworld MT6735M :

You have earned a +Rep because you are using Linux OS ... and you have provided me accurate informations Cool
I have installed Ubuntu (Wily Werewolf) and Windows 7 on my pc ... and I use both at the same time.
The stock rom that I have posted you is the same of the official site (I have unpacked the "vk6735 ROM update.tar.gz" and I compared it to my stock rom).
The TWRP that you have posted me seems old ... so I have made a new TWRP (3.0.2-0) for your device ... I hope it will works well .... you will find it at the next link :

I suggest you to install the last version (v5.1604.00.100) of SP Flash Tool for Linux ... and try to flash once again the stock rom ... you will find my tutorial about it in the next thread :

Above all, try to flash the TWRP that I have posted here ... and see what happens. Looking forward to your feedback Smiling

Again thanks a lot for your time and help!

Unfortunately it did not work Sad

But I got a little progress, the error is not the same, following your tutorial SP Flash Tool has a little connection with the phone, but ends up with an error:

Hi pichouss !

Do you have already installed OpenJDK on your Linux OS ?
Do you have already installed android-sdk_r24.4.1-linux.tgz on your Linux OS ?

Just out of interest ... which distro and version you have installed on your pc/notebook ?

RE: Bricked VKWorld VK6735 - pichouss - 2016-05-23

I replied to your Linux related questions in PM ;)

Hi pichouss !

If you can't use SP Flash Tool on Linux OS ... I suggest you to use Windows OS ... so you will can try to flash the TWRP (3.0.2-0) that I have made for you.
