[Q] Mtk6577 Preloader dead/restarts - Android Q&A, Help & Troubleshooting

Here is my complete problem,
My device is Micromax a110(canvas 2) (AKA Cynus t2 or Qmobile a10) (The board is s9081).
I was in CWM and i flashed the galaxy custom rom(meant for my device) it worked nicely after due to some reasons i rebooted it on factory mode after that the device went to bootloop, the bootscreen shows and then restarts infinitely , so i decided to reflash the stock rom (Stock recovery) so that i removed the battery and connected the phone via usb, now my phone detected as MT65xx preloader and in a second it disappers instantly. i tried testpoint too it doest works ,it is not the driver problem since the device needs to be detected and stay detected for that long to install the drivers(and i do have the drivers), is there any solutions for that? any help is appreciated, thanks in advance.

MT6577 preloader recovery

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

Clone N2 brick after ROM update

Hi Masters,
I just like to inquire if I can still unbrick my clone Note phone. It has same spec as the HDC 5.7 Lord N9588 same box with NeoI brand. The main reason I flashed the ROM is because the accelerometer and GPS is not working so I found this ROM in needrom.com under HDC Lord N9588. as instruction says do not change anything in the setting (includes preloader). It successfully flashed the ROM but after reboot, the display is messed up and showing different color vertical lines. same as in the recovery. I believe that the phone still boots up, only the display messd up as I still can hear a sound every time I press the button and the screen and can hear volume sound when pressed. I still have the original ROM but the problem is it does not connect to SP flash. Last time when I connect to SP flash I can see MTK PReload VCOM USB when connected, now I can only see Preloader VCOM USB and gives errorS_COM PORT OPEN FAIL ERROR (1013) .already tried reinstall usb drivers.I can still access the phone trough adb shell but could not flash using fastboot at it says device not detected.
Thanks for any advice in advance.
Regards,
Ferdie

So, my phone is hard-bricked (doesn't boot at all) and it's no longer responding when connecting it via usb cable. I was about to flash it but couldn't complete the operation, now everything is deleted including the operation system (the ROM), the recovery mode, the preloader etc....
So what to do?
