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
I have same situation. Did you find any solution for this?

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

On my phone, mine has the same chip as yours, to flash in preloader mode, I do it in this order,
1 connect phone to pc via usb with battery removed,
2 load flashtool with scatterfile and rom to flash,
3 click on download in flashtool,
4 put battery into phone
SPflashtool then searches for the preloader driver, loads it briefly and then loads the DA Usb Vcom port driver and then proceeds with flashing
This will only work if you have the usb vcom preloader drivers installed on your pc
To check if you have preloader driver installed, open device manager on your pc, connect your phone with usb cable and battery removed, put in battery while watching device manager, if driver is installed you should see 'Preloader Usb Vcom port' appear in the ports section,
but it will only be there for a few seconds, and will dissappear again. If you do not see this you need to install the Vcom driver.
Hope this helps
you help me a lot man !!!!!

Do you see the preloader driver in device manager when you connect your phone as I described above?
Which build of SPflashtool are you using? the tool is quite buggy and sometimes helps to try another version

Help for god sake !!
Ok, i think the only way your going to unbrick your phone is to flash the exact correct rom for it, Do you have a copy of the stock rom for your phone suitable for SPflashtool?
The link that you show is for a Feiteng H9500, that is very unlikely that it will work on your phone, the reason your phone is bricked is because you have probably flashed the wrong preloader block, and that is whats causing the trouble, you need to make sure you have the correct rom for your device before you start.
I think the only time you had a little success is when you accidentally entered preloader mode and if it were my phone I would concentrate on getting the preloader driver installed. There are some tutorials on here to install the drivers, it can be a bit tricky, and not all mediatek devices are the same, so a bit of trial and error may be needed
Once you have the Preloader usb vcom drivers installed I would then attempt to flash just the preloader and dsp_bl blocks initially from the correct rom for your phone, and then if successful flash the remainder of the rom, without preloader and dsp_bl
If you flash the wrong preloader/dsp_bl you will almost certainly brick your phone, so it must be either from a backup you have made of your original rom or from the exact stock rom for your phone.

So the preloader vcom driver is installed ok on your pc, but you do not see it when you connect your phone, maybe you need to connect in a different way, on my phone I have to connect switched off phone with the battery removed, and when the battery is put in, then you see preloader driver pop up in device manager, there are many different MTK phones and different ways to connect.
The stock rom you have should be fine as long as it is the correct one for your device.

If your phone now is completely dead, probably your only hope of reviving it is by using the test point, see 'Modes of the virtual COM ports', here.....
http://forum.xda-developers.com/showpost.php?p=38369102&postcount=11
Ive never done this procedure, so cant help much with it, but if you search these threads for mediatek test point or similar, you might find some info on it

As I said, Ive never done this myself, only read about it and have no idea where the test point is on your phone, they all appear to be in different places, on an mt6577 I had previously it was easy to find, just by the sim slot, there was no need to even strip the phone down, but on most other models they all seem to be less accessible. It will be somewhere on the main board I would imagine, usually, but not always, a small round brass dot about 2mm accross, and I noticed while searching that some are marked 'KCOLO' or similar. I believe also from what I've read that the manufacturers use this method to input the factory rom, so it must be there somewhere, its just a question of locating it. The best method to find it apparently is by testing different points with a multimeter to find one that corresponds with your battery output.

The thing is, I am having trouble flashing the Stock ROM to my Lenovo A1000G as it has been dead and it doesn't turn on anymore.
I have installed MTK / MediaTEK drivers (After reading multiple threads and guides over the internet) and I have installed these 3 specifically -
1) MediaTek DA USB VCOM Port
2) MediaTek PreLoader USB VCOM Port
3) MTK USB Port
But the thing is whenever I try to plugin the device to the Computer pressing the Vol (-) button - it shows up in the Ports section as MediaTek DA USB VCOM (Android). Now since it is appearing like that, I cannot flash or do anything in general. Because the device is getting detected by the PC but the one that shows up in the port is showing up as the wrong one. It should have showed up as MediaTek PreLoader USB VCOM Port but it isn't happening like that. I have tried so many variations to install drivers / uninstall it. It just doesn't work.
Can someone please help, since I don't have much knowledge. I do have the Stock ROM ready and the device is probably hard bricked, so can't install drivers using the Pdanet method. So what can I do?
No help? Please someone. Bump

I'm trying to install stock rom to Lenovo a2016a40 (Lenovo B). After I connect phone to my system using volume down key preloder appears in device manager but after few seconds it disconnects from pc. I have tried to install via SP flash tool but it fails and gives error.
I have tried to update all mediatek drivers , changed port and cables but still I'm facing that issue , please help with this issue.
@sangram200
AFAIK Lenovo Vibe B is based on Mediatek chipset, hence SP Flash Tool seems to be the correct one.
It just disappeared from Device manager on PC
It simply disconnects from pc after few seconds ( disappeared from device manager), hense SP tool fails there is no issue with flash tool , its the connectivity issue but I don't understand why it disconnects from PC ,I have tried to update drivers and changed cables and switched ports but still having same issue.
@sangram200
I'm pretty sure you haven't installed the correct USB-drivers as needed, for example the MediaTek MT65xx USB VCOM Driver: this USB Driver will make sure that your MediaTek Android device is properly recognized by your PC, it ensures that there will be no hiccups while you are trying to flash a custom ROM or when you are trying to root your device.
