[Q] MTK-6572 Startup Problem - Android Q&A, Help & Troubleshooting

I have a Symphony W85 MTK-6572...
I recently installed a Custom ROM after which my Phone turns off instantly on the Boot Screen... I can still enter the recovery mode and have tried a lot of ROMs which previously worked on my phone... But now the phone turns off instantly after the boot screen appears...
Finally, I downloaded the correct Stock ROM and tried to flash using SP Flash Tool...
I removed the battery, SD card, sim card, then connected the phone by holding on the vol (+) button, the phone connects and disconnects instantly from the USB port... The MT-65xx Preloader appears and then disappears instantly in the Device Manager... So I cannot install the Stock ROM also...
Please, I am in desperate need help regarding this issue...

[Q] No power to Wiko Darkmoon (MT6582) after Recovery Flash attempt

Hey all,
In an attempt to load the custom ROM from http://forum.xda-developers.com/showthread.php?t=2658343 I kinda broke the phone.
Part of the steps is to flash the custom Recovery screen.
In the steps you use the Scatter file that's provided and load that up with the SP FlashTool.
Problem though is that I started to get the error SP FLASH TOOL ERROR : (8038).
I then read that by using MTK Droid Root & Tools, I could create a new Scatter file that would fix the error...
Created the new scatter file and then when I loaded it, I got the Big Green Circle saying everything was cool.
Rebooted the phone and it wouldn't come back on.
Crap.
Tried loading into the Recovery screen using the volume and power button, but nothing shows up on the screen.
Tried plugging it into my Win7 and WinXP computers but neither recognize the device and nothing shows up on the screen to say that it's charging.
Is this phone completely gone or is there something that can be done?
Old thread but somehow connected brand new experience to be documented:
What I just experienced was, after a cancelled attempt of flashing recovery, the phone was off and didn't go back on. I tried fiddling with the buttons and assumed it was bricked. Fortunately I didn't give up too soon. It was only after pressing the on button for a very extended time (>30secs?) that it came back to life. It didn't boot further than Wiko logo, but the key reactions were back to normal concerning reboot, booting recovery and cold start.

BROM ERROR on sp flash tools, HELP!

i have a tecno f8 device, it has MT6589 processor. The phone hanged one time and i forced restart it holding down the power button for about 10secs, unfortunately when the phone restarts, it kept coming on and off, and here is where i think i bricked the phone, the phone's battery was at 10%..i pulled the battery and loaded the cmw recovery plugged in the charger, and i tried reflashing my custom rom (miui v5).. the rom installed completely.. then i went to 'reboot now' from the cmw menu options, and then my phone refused to come on, its just dead, led light wont even come on if i plug the charger, and i cant boot into recovery.
i have been to a number of android developmental blogs trying to solve this issue, i even download the stock firmware and i tried flashing with sp flash tools, but i keep getting various brom errors, the 3149, 5069 no space errors.
can anyone pls help me get my phone back on?

MT6582 chipset phone dosent boot after flashing with sptool

Hi,
My friends oppo neo 5 went into bootloop and we decided to flash stock rom to solve it. We had done the same previously and it worked without any problems. This time after initially flashing it stayed on the boot screen itself and we decided to flash again but this time instead of download on the sptool, we used firmware upgrade and after flashing, the phone wont boot up. when we try to power it on it vibrates for 2-3 seconds and then continues to vibrate after an interval. The phone is detected in device manager when its plugged in to the pc as mediatek usb port and mediatek da usb vcom. The phone is detected in sptool and we are able to flash and it gives the green tick, but there is no use as the phone wont boot up.
