Hey,
I have been years just reading these forums but never made any posts, so thats why I cannot post to development section anyways. I happened to totally brick my phone by flashing wrong preloader into it. However this morning i succesfully reflashed it and now I have somehow working phone (just need to find new rom now) but anyways. This thread is to help other people who has semi bricked their phones as well.
Current situation.
-Phone doesn't charge,
-Phone doesn't turn on (nothing happens)
-Computer sees phone for few secs, so you have "META mode" access. If your computer doesn't see your phone at all make modified USB connect the 4pin to ground. This is what I did actually. If that doesn't work you can google for test points.
My device:
MTK6575 (Fake mt6589)
512MT RAM (fake 2GB)
800x460 resolution (fake 1920x1080)
4GB internal memory (fake 8gb)
5" screen
2200mah battery (fake 3000mah)
OK this is the prodecure that got my phone back to live!
Install windows XP (Yes, windows 8 didn't work for me. most likely drivers are not ready for it. I will not write steps how to install windows xp)
Install USB deview
-Google it, download it, extract package and run it
-Remove all drivers related to Mediatek, android, usb vcom etc.
Download and install VCOM USB Drivers
-Download these drivers http://www.mediafire.com/download/31nddwqdot5ajp2/MT6575+USB+VCOM+drivers.zip
-Put your phone battery in (50% charge) required. wait 10s. Take battery off and connect your phone to PC as meta mode ( modified USB cable, VOL+/- while connecting, you can read more about this from here: http://forum.xda-developers.com/showthread.php?t=1943442
-When your phone is connected it will disconnect after ~3-5seconds. Now you have to wait in device manager connect the phone right click the device when it shows up. Install driver from the location where you unpacked your VCOM USB drivers/2K_XP_COM/ dont automaticly install them but manually. After windows have found drivers UNTICK show compatible devices. And MANUALLY select preloader driver. Now it will install it the next time the device connects. OK now we have Preloader driver in place. Notice that we will install one more driver later needed in flashing procedure. Disconnect phone.
Now download compatible rom. for me My backup was not working, but this rom worked out perfectly:
http://search.4shared.com/postDownload/wILsUT7J/MTK6575_S4_FLASH_TOOLS_YEDEK.html
Download SP Flash Tool v3.1222.00, extract it.
Ok lets recap what we have now:
-preloader drivers
-phone disconnected
-SP Flash Tool v3.1222.00
-back up we can use to flash
Open flash tool, enter scatter file and go to Format
-Select Format whole flash except bootloader and nvram bin region. -> connect phone -> succeed
-Select Format NVRAM bin region ONLY -> connect phone -> succeed
-Select Format whole flash -> connect phone -> succeed
Ok. Next we need to flash compatible rom this part is tricky. Read before doing anything.
-Disconnect your phone, enter battery (50% charge required)
-wait atlaest 15seconds, and remove battery
-(I dont know why those steps were required, but didn't work without it)
-Open SP Flash tool select scatter file and select all checkboxes
-press download
-connect your phone in META mode with Preloader drivers we installed before.
-Now red prograss bar will start going and phone will disconnect After it reconnect We want ANOTHER drivers are located in the same place but now we need to select Mediatek DA Vcom USB drivers. If everything went fine you get yellow progress bar and it will reflash your phone! :victory:
In the last part if you got Error 5054, This is good. It means your phone is still alive! but your current preloader does not match the data you are going to flash. So you need to go back to google and download other rom try flashing everything (thats what I did, before hitting jack pot, eventually you will find compatible rom)
If you got ERROR 3002 switch back to SP Flash Tool v3.1222.00 newer one doesn't work!
I got some other errors as well when flashing and I solved them but didn't write down the errors so I cant remember them sorry
Remember before connect phone as META mode. Plug in battery with atlaest 50% power wait 15s. remove it. and connect the phone to PC. This was the mysterious step I was missing when struggling with this 5 days!
By the time of writing this article I got my phone working rom, everything works.
GOOD LUCK
ps. Sorry for typos.

Sir,
I port rom cm 12.1 on my MT6582 Lenovo A328 device. As i power it off, it takes time to open and few seconds TWRP appears and i reboot the system and suddenly stucks on the cm logo and i removed the battery and open again and try and try again and it does not open. I thought that my phone is hard bricked so i connect the device without a battery to the computer via usb cable. Open the sp flash tool and open my scatter file and download....but sp flash tool download progress is color red which means connection on port problem. I open device manager and saw ports....MTK USB Port appears to be the kind of my driver's device and I think that it should be MTK Preloader VCom to be able to flash the stock rom.......Hope you understand and thank you so much for your time.....
I TRIED TO REPAIR IT MYSELF AT HOME BUT YGDP FAILS AT 98%... AND SP FLASH TOOL GIVES BACK "S_BROM_CMD_JUMP_DA_FAIL( 2035)" found no solution on internet... it can still boot to fastboot mode... and when i turn it on it stucks at mmx logo.
please help...:crying::crying::crying:

( Solved )
1) switch off mobile and then connect it to pc
2) open device manager when shows your device then click shows hidden driver in device manager right click on all your device drivers and uninstall it
3)then disconnect phone and disable driver signature verification from windows setting
4)connect phone to pc pressing volume up button
5) in device manager you will see there unknown device or mt65xx preloader just right click on only unknown device and update driver manually ( the driver name mtk usb port) dont install mt65xx preloader driver
6) open sp flash tool select scatter file connect phone to pc when it shows mtk usb port in device manager click on download button
YOUR PROBLEM SOLVED if not work i am not responsible for your device bricked
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.
