Hi
I flashed the phone with invalid firmware using SP_Flash_Tool.
Now SP_Flash_Tool and Windows doesn't see the MT65xx Preloader USB device after disconnecting/reconnecting the battery.
The phone doesn't switch on.
Is possible to recover a preloader on MTK6577 (Zopo ZP 900) using the flex cables or other methods?
Thank you

MTK6577 Tablet
Hey guys .. any solution ?
Lenovo A2107A-H, Dual SIM dead after SP-Flash
I stand in a row with you all, I also have killed my tablet with SP-Flash, It appears as Alcatel Single RNDIS Interface in Win7 control panel's network adaptors and in Win8.1 as "unknown device". I already uninstalled the drivers, the Win7 needed to reboot after that, but re-installed the same sh** after reconnecting. I have heard about another tool, not SP-Flash, which shall be able to "find" the tablet on the USB bus, but I don't remember the name.

I un-bricked my Lenovo P770 yesterday!
How to do this:
1) Download and install "MT6577 USB VCOM drivers" -drivers for your phone
2) Open Device manager in your computer. Then "View" and "Show hidden devices" (do not close Device manager)
3) connect your phone to PC by USB cable (without battery, some phone with battery)
4) In device manager, in Network adapter (in my situation, after few second) shows "Alcatel single rndis interface #. . ." - it can appears and disappears!
5) When "Alcatel single rndis interface #. . ." appears click on this device Update drivers->Browse my computer...->Let me pick.. and here you should see "Mt65xx Preloader" if not you should find your driver.
6) When you update this driver you could use Flashtool v3->loading scatter file (you can find your android on needrom website. for example: P770_ROW_S110_130204_707WOW) -> check only PRELOADER and click Download
then connect your phone again to USB (without or with battery) and wait some seconds.
GoodLuck!!!
You can control on needrom website
I have the same issue. mediatek S8 - mt6577 7inch tab
Hi all, I have a Lenovo P780 4GB that I flashed successfully with SPFT, P780_S125_130529 ROM from needrom.com. from there the phone will not boot but I can see is a red led charging light glowing while connecting it to a computer or charger. The device is not getting recognized by VCOM drivers so no use with flash tool any more. the only thing I see from Device manager is Alcatel Single RNDIS Interface #2. when I plug the phone to the computer I can hear the device connected/disconnected sound, Tried to reboot in to recovery and meta mode but the phone simply does not turn on. Anyone knows how to fix this problem?
Is there any other way I can get the device to change modes or rather a way to get it to be recognized by the PC?
a solution to fix the device will be the best.
Thanx for the help
Hi All! Sorry for my bad english.
I want to upgrade the ROM Lenovo S898T . I remove the battery as instructed , and then connect the USB . It appears in the device manager vcomm preloader for a few seconds and then disappears so that you do not see flashtool .
The Preloader MT65XX Vcom Driver is installed.
Why does the Vcom driver?
My os is Win7.
PS:
Someone can share a multilingual ROM ?
Thank you!

Hi there! First try this:
1. Change USB Cable
2. Change USB Port!
3. Open device manager
4. Look on port tab ... If it have that + click on it...
5. Now and only now plug the phone Powered ON.
6. on this step you should see Lenovo ADB Device/ Lenovo Composite ADB Device
7. This means that your drivers are installed correctly.
8. If you want to flash firmware you need to install another tipe of drivers!
Hei Stympy,
i´ve tried it step by step but there came no notification that there´s a new ADB Device (
any other Ideas?? Maybe it is a USB Port problem of my phone?
