Little Guide :

What is it ?
in MTK Android there is many Partitions in your phone. like Preloader, Recovery, Bootimg etc..... if somehow Preloader get Corrupted then you phone will not able to DETECT WITH PC !!! in other words you will have phone with BOOT DEAD.

How Preloader get corrupted ?
There could be few reasons but main reason could be that someone or you Flash your complete phone (include Preloader) with wrong files or with wrong ver. Also there could be reason someone Delete Preloader or you Deleted.

How could i know my phone have preloader dead ?

Preloader can be dead if some one Flash it wrong and after flash your mobile will not detect with pc any more. for confirm
open device manager
take battery out from phone
insert usb
insert battery
and check is computer detecting any device
If it's not detect then you have phone which Preloader is dead AKA Boot Dead

How can i repair it ?

you have to disassemble your phone and take pcb out. check there should be some Golden points. check these points there should be written on them Rx,Tx,GND,Vcc,Vcharge etc... check there should be written "COLO" or "KOLO" or "KCOLO" you have to Sold that point with GND After Sold Attach usb now your phone will detect with USB !! and now ready to Flash.
In some phones "COLO" or "KOLO" or "KCOLO" not written for those type of phones you have to test all points one by one Short Golden point with GND and attach usb cable which point short with gnd can able to detect your phone by pc is Force Preloader Mode Test Point !! Keep in mind Don't Short Vcc,Vcharge or any other pin which have 4.x Volts also i had tested "Colo" or "Kolo" or "KCOLO" don't have any kind of volts..

So Please share your Researched Force Preloader mode TestPoint Picture with Model name

hy bro i have I9060 MTK 6572 clone i flashed with one file the phone is dead now i try with alot of files not working even the back up not writing . plz help me
Now phone only taking info woth volcano box nothing doing more

[Proacc]

Hie One thing you can do is to open up your phone. Remove the shell covers. On the PC board look for GRV Golden point and also KCold golden point. Get a soldering gun and solder copper wire to connect the two points. If you can flashed without the battery, then run SP Flash Tool and load the backup scatter file. Click download on the SP flashtool and connect usb cable to your phone and it should start the flash process. Once down load process finishes remove usb cable, de-solder the wire you connected two golden points. re-assembled all shell covers and put back the battery. Your phone should start up.

I have a Micromax A110 that uses :

H/W Ver. : V1.0
S/W Ver. : V1.11

I think there is a matter of unstable COM port in this phone, As per Faisal_Computer told, I disassembled my phone and sought "COLO" or "KOLO" or "KCOLO" and ended up with DP, DM, TX, RX, OE, VCHG (nearby the camera) and G, V (nearby Battery Connector).

I find out somewhere in a forum that I can flash it if I short or solder DP, DM to RX, TX, is it an alternate method to make a stable COM Port as soldering KCOLO/KOLO to GND is.
If not, Please tell me which points should I suppose to short.



Thank you.
