This device is a Huawei mediatek

Your approach now to solving this problem is totally BOOT REPAIR VIA MEDIATEK TEST POINT
the test point for detection are kcolo and colo....

If you are familiar with mediatek dead flashing, you may proceed to find the test point if not you may have to send the device to a service Centre for repair..

***First you need to disassemble complete and take out the PCB (board)


***The test points are mostly with no VOLTS when you test their power

***Short the test point (TP) to any GND and insert BATTERY, thereafter connect USB

***Load factory files in any suitable software and flash


****Huawei TP are found in the archives of supported GSM boxes for repair

Take complete pics of pcb for further help

Seems you might have to follow the fix outlined by @droidmobitech
Seems like a dead preloader.
Does the phone still get detected in device manager when you connect?
If yes, what does it get detected as.

It seems like the thread starter has left the building. Will it be acceptable if I revive the conversation?

If so, I will go on and answer your question @basim (assuming his/her issue is the same as mine): no detection at all. Looks like a hard brick.

@droidmobitech will you still help me out if I could provide the PCD photos?

Well, it did not take me too long to fine the "[Tutorial] How to revive a totally dead Mediatek Android phone by joining the Board Mount Points" thread. This should be enough to get me started. To be continued...

Yes, your device has the Mt6592 cpu,

It will be appropriate if you could send pictures of the pcb for help

You may try and identify the test point, usually Colo are kcolo should be written on pcb , they are test points. ....

I assume you can go ahead, after disassemble. ..
If not, using a voltmeter, test all other unlabeled points with GND

The test point has no such volts on pcb

Short that point to gnd


Hopefullly, it should detect


If this does not work then an emmc replacement is the final solution

These are the images I just took.

Hope they help? I currently do not have a multi-meter present, should I hold off, or can you guide me through this with only the images?
I could not spot Colo nor kcolo on the PCB.

Thanks


RE: Huawei G750-u10 completely dead after flash ??? - barthodian - 03-31-2017

Am I doing something wrong guys? I was hoping that tutorial was going to help me out, but none of the labeling such as colo or kcolo was found on the pcb. I do see the "w" shaped dots right next to the full size sim slot. Could one of this be it?
