How to install Android with LB

Hi guys,
I think I messed up my phone big time. I had problems with turning on wlan, so I tried Rebooting and Factory Reset but without success. Next I wanted to reinstall android via TWRP like I would do it with my PC. Now I have a Phone with an empty internal SD Card, locked bootloader and no idea how to fix it.
The PC Companion or any other program does not recognize my phone.
Is there any way to install Android again with a locked bootloader or can I unlock the bootloader without android?
Hopefully anyone knows a solution and I do not need to buy a new phone.
Thanks in advance!

thanks a lot but so far did i get myself before even posting here ...
i cannot enter flashmode via android obviously and via the volume button is not working, the led does not flash and flashtool is not recognizing the phone when i try it
Plug it into a wall charger for 24 hours and then try again.
Also, sone information from your device manager in your pc may help and what scaly you flashed in recovery to get into this situation. Its very difgicult to offer advice on such limited information.
Problem is fixed, i got a new mainboard ...

Partially bricked Mi4c mi-globe 7.2.9

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?

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.

is a gift, but i know is from gearbest but if i can resolve the problem here is better than send the phone to chine and all the process.
Rommco05 said:
hm another bad situation. For your model isn't (or I don't know where) full firmware which can be useful. Try this, install HiSuite to PC and here is one section to repair phone, follow instruction in this program.
edit: try reset your wifi setting, setup for short without possword and try again download via eRecovery latest version

i have try the two methods but don´t work. via wifi fails everytime. via hisuite the recovey said the phone is not supported

Are you able to flash twrp?
Unfortunately, I can not get in any way to restart with recovery from SDcard but it does not recognize any firmware stops at 5% with the following message (software install failed).
thank you!

No! I have already explained it does not enter fastboot and is not recognized by the PC, the only way is sd card but I tried various firmware stops at 5% even seza sd card.
When it enters sdcard recovery mode and connects to the PC it is reconnected in this way as a CDROM (linux file-cd gadget usb device).
Thank you!

I know I just have to try to give it back, hoping it's a guarantee with the Chinese people, I've already made a complaint that after two days the smartphone gave me problems, but the support office opens on 28/8.
Thanks for everything!
