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

Hi All

I installed a custom ROM but it was getting stuck in boot screen ,so i did a auto format flash which deleted all the data in the flash using SP flash tool v3.1312.0.139 . and as I disconnected the phone from PC it got hard-bricked. even if i connect to PC, SP tool is not able to recognize the gionee p2 so I cant do any thing .
can't switch on the phone and not getting recognized in SP tool flash.
Is there a way to fix it or to send the rom data to the phone flash ?

Regards
Arhdna
