(06-11-2014, 02:48 PM)hovatek This guide will come in handy for Mediatek (MTK) and Spreadtrum (SPD) Android device users who suddenly end up with a totally dead device that won't power up or respond to buttons (but makes a sound when connected to a PC) as a result of intentionally or unintentionally interrupting the flash or backup process. Interruption could be triggered by shaking / unplugging the USB cord or even an error popup / prompt in the tool you're using. On rare occasions, its triggered just after a successful backup / flash using a Mediatek flash / backup tool

Tips to speed up reviving your phone


  1. Take out and re-insert the battery then try powering on (this is the quickest approach)
  2. Disconnect / take out the battery > Connect the phone to a charger without battery inside > Slot in the battery while the phone is still connected to the charger  > Press the power button
  3. You could keep pressing the Volume up + Power button while charging
  4. If your device has an inbuilt battery then hold down the power button, connect the device to a power source (charger) and wait till the phone comes up
  5. You could remove and boost the battery using a desktop / external charger then resume internal charging.
  6. Uninstall then re-install MTK preloader vcom drivers or SCI drivers for SPD

I thought this might help people who are stuck with hanged/bricked device due to interrupted flashing and dont want to wait too long for battery discharge.
Recently I was trying to backup firmware on my infinix X690 mtk device which got interrupted.. later device was not detected in the PC . shows unknown device . nothing works and only solution was to disconnect the battery by opening the device or wait for the battery to discharge completely . it might take weeks before it drains completely as its consuming very less power in this state . also who wants to open their new handsets .. right ?
I waited for a week . charging continuously to check if its restarted but it never happened . I also read in this forum that one guy waited 21 days but battery didn't drain . we have 6000mah battery phones these days . I got impatient .. how can I drain the battery quickly when its bricked ?

all We have is usb port to access the damn battery .. why not check if there is a power in any four points of the micro-usb port of the device ?
Bingo! in this bricked state its data pin which is third pin in the micro-usb port was oosing power .
now get a spare micro-usb cable .. they are pretty cheap these days . cut it in the middle . we only need green wire which has power and black which is ground .
attach two small leds to it . I could attach only two . as we have a limited current and more load will cause break the circuit .
This is our power drain circuit . connect micro-usb to the device . if leds are glowing you are done . this might still take take one or two or three days depending on the battery power state. but now you know that its draining faster. you don't even need to touch the device as long as leds are glowing . after some time you will see leds are fading and soon they will switch off . battery drained successfully !
connect the charger . it will start charging from 0% .
we are done .
this method is safe and doesn't require any special tools or things . for leds we can use leds from led bulbs as well if not available .
at least you have the idea now .
Cheers !!
WHEN BACKING PRELOADER SELECT REGION EMMC_USER AND NOT EBOOT IN SPFLASH TOOL .. IT WILL CAUSE BRICK IN LATEST MTK SECUREBOOT DEVICES .
LATEST WWR MTK TOOL CAN EXTRACT PRELOAER.BIN FROM EMMC_USER REGION PRELOADER DUMP SAFELY .

disconnect / reconnect the battery then you can reflash

disassemble the device, disconnect / reconnect the battery of the device then reflash your device
OR you wait till the battery drains then charge a bit and reflash
