Partially bricked Mi4c mi-globe 7.2.9

[DeAntman]

Good day gents and ladies

Well let me start from the beginning.

I'm was using mi-globe 6.12.22

Last week Friday evening downloaded 7.2.9 mi-globe,read around the mi-globe forum.Didn't see anything funny so flashed via twrp on Saturday morning.Hmmmmmmmm this is when all my problems started.

Basically what I should of done is download 7.2.9,new 3.0.3 twrp for norgat,go into recovery flash new recovery, restart recovery,flash 7.2.9 and then have happy days.But it wasn't to be and now I'm basically sitting with a useless mi4c device.

The device works but warms up and I only get about 4 hours battery life.

If I try boot into recovery I just get black screen.

If I connect device to PC it is not recognized, have tried 3 x different laptop/PC's and different cables.

So fastboot,mi-flash,mi-unlock are all not possible as device is not recognized.

I have been trying different solutions without any success.

I think if it would be possible to root device directly without PC then maybe it will be possible to get flashfire working and I can flash new norgat recovery?

Any suggestions would be greatly appreciated?

NB.I have tried loading Qualcomm drivers ,google drivers etc etc.no luck can't connect my device too PC,either get device not recognized or the PC doesn't even see the device.Enable USB debugging etc etc nothing works.Been fiddling for 4 days!!!!!!!

Tried to root with kingoroot,framaroot directly on device etc nothing works?

Please help,else device is a nice piece of plastic that holds paper down on my table.lol

Is usb charging via pc working and have you tried miui updater? , This seems weird state you have ... If none working might be tried deep flash cable flashing ... Or go to nearest service center. Hope that help. Best luck.

Hi,yes USB chargers device via PC but that's all.
How does one deep flash,could you post link please?
I bought the device in China about 18 months ago,Xiaomi never sold mi4c in my country so doubt they could help me locally.

Seems I have soft bricked the device?Tried every thing no solution.

If it would possible to root without USB cable I could maybe try flash new twrp via flash fire?Then could wipe all and try start again?

You havent answered the miui updater part, have you tried flash miui rom.zip, using miui updater apps ?

Does fastboot mode boot on your phone ? i mean the bunny sceen showed up ?

For dfc here the link http://xiaomitips.com/guide/miui-deep-flash-engineering-cable-solution-to-non-edl-device/

Please take dfc as last resort. And do research more on this... Do with your own risk. Good luck

Hi,

Yes sorry I have tried updater, I download rom start updater it starts but after about 2 minutes stops and phones shuts down.

I then have to restart phone with long press of power button. It restarts but nothing has changed.

Wrt fastboot it goes into fastboot but this is useless cause no Pc can see my device and if it sees it it sees unknown device, spent countless hours trying different things without any success.

Seems have soft bricked the device, phone works but gets hot and battery life maybe 4 hours if I'm lucky?

Not sure what more today?

Before this has your pc able to use the miflash ? Try to follow this guide to setup it correctly http://en.miui.com/thread-136188-1-1.html ... I follow this guide and the adb n fastboot even works on an old pentium 4, 512mb ram, win xp laptop.

Ps: I think, its only a matter of incorrect driver setup on your side, best luck.
