So if you read full phone you will learn all methods with detail.
MTK AND SPD BOOT REPAIR VIA SHORTING MICRO USB BOOT PIN:
This method is used in some Chinese mobile phones that are based on Spreadtrum and Media Tech CPU. If we brick phone by flash wrong firmware to phone. phone wont boot and anymore and unable to detect via usb cable. So we short boot pin to alive phone again with correct firmware file.
IF Micro USB connectors pinouts are same as below then we need to short pin 4 to GND to then mobile phone will be detected by usb cable if this pin have no connection the we need other methods.
- VCC
- D-
- D+
- NC {Boot pin in most Chinese phones}
- GND
MTK BOOT REPAIR VIA SHORTING KCOLO PIN:
This method is used in MTK based smart phones only. In this method we have to short kcolo point with gnd on board to recover dead boot mtk mobile phones. We need to find kcolo point on cellphones board and the short with ground.
How to connect phone after shorting kcolo point with ground.
After searching correct kcolo point on board we must short it with gnd before connecting usb cable. some time we don’t need to connect battery with phone. but in some cases we must connect battery to flash bricked mtk phone.

We can also modify micro usb cable to recover bricked android mobile phones. Some companies making boot jig to sale their customers and this boot jig can found easily in market in little amount.

The switch is connected to micro usb connector with two copper wire at GND and Pin#4. When we press button on cable it will short pin4 and ground and allow ability to boot bricked android mobile phone via usb cable.

The only way is you need correct firmware from someone or from same phone. Then flash it will be ok. If phone not being detected by Computer then use boot JIG or make your own cable like shown.

Hi,
If you have bricked your MTK phone and now you have not normal connectivity, You can unbrick by shorting KCOLO point or by using JIG or making your own cable all written above. If you have problem regarding firmware mismatched then the only way just search compatible firmware for your phone or read from same phone. I can’t give help regarding this problem remotely because i have not firmware for this model.

Brother You Have? Kindle fir hd stuck in Boot Logo, Solution?
i have recently purchased BlackBerry key2; when i plugged charger it stops working only green lihgt on top is constant. i have get checked from everywhere but no luck on of repairman said its deadboot/loop and wont be repaired unless its detected on computer. can anyone help?
Hello,
thanks for your information. My question is, how can i identify the sprd boot like 6531, 8810 and others? How can i identify the exact boot for the respective phone?
By Matching loader one by one using professional mobile phone flashing software or may be you can get information from official firmware. simply you can google from respective model firmware you should have all information in firmware post page on internet.
My mobile has usb port type C and a chipset Mediatek.
I think that is the same connections of the SPD.
So, for USB type C, how should be the connections?
Press volume up and down and then insert usb cable.
Sir mine is Itel p33.
Flashing process failed with SPD upgrade tool and the phone is totally dead won’t boot, won’t charge and can’t be detected by pc. Is there any solution?
Use jig if failed then JTAG method should be tried.
