Do you have Motorola Device Manager Installed?
If not then Download Here: Click Here

Yes it is installed properly

Ok.
First check this : First open Settings then navigate to Storage and touch the upper-right corner for the USB computer connection options. Make sure Media device (MTP) is selected.
If this doesn't work then well you need to update the driver for your phone which your computer is using. Go to device mangaer on your pc and click on your phone name and update all drivers(left click to see options).

Still not working

It worked for half hour and then gone again

To remove old driver . Goto Device Manager and Connect your phone in META . Preload Device will be displayed . Quickly right click on it uninstall.

Use the installer that automatically installs all the signed and signed drivers automatically. Will do the link when I find it.

I have firmware, but is it the right firmware?

So, a while ago I soft bricked my lg tribute, so I downloaded the firmware for an Lg tribute 2 consisting of a tot file and a dll file, the dll file is called lgupwebdl.dll, so I assume the firmware I have downloaded to my computer isn't the right one for my hardbricked lg tribute 2 (I'm really bad with devices I guess) since now I'm trying to unbrick my device with mediaTek and Sp flash tool. So, will the firmware I have right now cut it for mediaTek? If it won't, could you point me to the place where I could download the proper files to unbrick my device using mediaTek? Thanks!

I can't find the scatter file. Is there a specific kind of rom that has one or what?

No scatter file
I got sp flash and the rom for my phone downloaded, but i can't find any scatter file. Is there specific roms that have them or what?

To flash using SP Flash Tool, you need a firmware package, not a custom rom. Every firmware package contains a scatter file in .txt extension. See attached image.
If you can't find scatter file. Maybe you got wrong firmware.

Ok, where should I get firmware package from? Phone is a Samsung galaxy s3 i9300 Canada. A bricked one. :silly:

k50-t5 soft bricked unknown device

Hello,

How u fixed it bro ?

when you install too much drivers some times it does some sh't. so power off the comp not restart it. if it doesnt fix it, there is a an app for PC called driver booster. it has the option to clean all the drivers for not plugged in usb devices. you disconnect all and run this . it will clear every driver that is not in use by any usb device. then when you plug in your devices it will recognize them and find the correct drivers without having problem.

Blue Light flash

Hey all,
I have Zuk z2pro z2121. I wanted more than stock ROM so I downloaded zui 2.5.344. I unlocked bootloader n rooted my phone as well as installed TWRP. "Tool All in one" PC software helped me to carry out above with ease.
While playing around I clicked "Lock Bootloader" and phone got switched off with indicating continuous blue light. I tried pressing vol down + power + Home button, and several other combination but didn't help. When I pressed power button for long, I got Zuk logo onscreen with a white flash on indicator for 1 sec and then again the blue light indicator.
After a little RnD after pressing power button till I got white flash for 3 times and the blue light got completely off. I don't know what to do further. I have backup of my boot , recovery and ROM. Kindly suggest.
Shoaib

Press and hold volume - and power . Release power, after vibration you can release the volume -. You will be in that menu https://ibb.co/f3vOHm . Go to device manager and check if pc recognize your phone https://ibb.co/bHqZOR . Open CMD in adb folder and write adb devices https://ibb.co/cwCg3R . Then adb reboot edl . You are i EDL https://ibb.co/cvjiHm . Use Qfil to flash stock rom

Didn't work...
Thanks for responding. As said, tried pressing Vol + Power and never got any vibrations. Tried Up vol + power, tried Down vol + power. No vibrations.
When I press power button with any combination, this is what happens,
After Approx 15 secs - 1 white light flash in place of blue along with ZUK pic on d display (stays approx 1 sec)
Still keeping power button pressed
After approx 7-8 secs - same as above
Still keeping power button pressed
After Approx 15 secs - 1 white light flash in place of blue along with ZUK pic on d display (stays approx 1 sec)
But now after this third time of flash, blue light appears and after 4-5 secs disssappears. If I leave the button only at this time, the blue light doesn't comes back.
If I leave the power button before or after this sequence, the blue light doeanon the indicator doesn't goes off at all.

What is happening when you connect phone with pc ? Is there any reaction ?

No reaction from PC.
I tried connecting to PC, earlier Tool all in one immediately use to detect, n now there is no response from the PC or the software after making USB connection.

Sir,
As I said earlier, I clicked lock bootloader, n when the screen went off, I disconnected the phone from PC. There is a possibility of the boot partition getting damaged or so. Kindly assist.

There aren't any ways to enter in fastboot or recovery , even in service menu . I think you should try deep flash cable to enter in EDL .

Will do as u say. Just one last thing, when I checked device manager in my PC, it showed the phone as other devicez "QUSB XXXX". Question is,
1. Any possibilities of recovery without going for a deep flash, as I got to learn it first.
2. Other part is, my phones battery seems to be drained now. So, it won't be a problem for a deep flash.

Could you give some print screen ?

The matter is that you must switch your phone to edl . Try this yet . Your phone must be turn off .
Press only volume up button for 10 sec and while keeping it pressed,connect phone to PC . Hold volume up until your PC finds a new hardware . It should be android phone - ShenQi composite adb interface . If it doesn't work I have no more ideas apart from df cable . This cable works on Zuk z2 and I think it should works on our Zuk z2 pro

Sir,
I managed to connect the phone via USB as 9008. Miflash not supporting my ROM. Will download Stock ROM n then try with QFIL and MiFlash as well. Thanks for all your support. Will keep u posted about the progres. XML file is not found in any ROMs I have. Miflash some error also but detecting the device. Is there any other tool similar to Miflash, which I can try..
Rgds

First use QPST/Qfil . Follow this guide https://zukfans.eu/community/threads/howto-flash-a-stock-zui-rom-zuk-z2-pro-z2121-only.57/
Do all steps .

Good day.
I tried QFIL as well as Mi flash tool. Both showing errors. QFIL displaying Qualcomm HS USB QLoader 9008. But when downloading content , it shows Sahara error with even initiating the installation. After browsing a bit, started eMMC software download, and found displaying COM20 No phone connected. Can u assist me to fix this. I mean the phone must be in download mode. But how ?
Miflash, on the other hand shows Hello packet error. Don't know how to fix.
Things I did to fix above errors,
1. Copied ROM to Qualcomm/ bin file
2. Copied ROM to C:/
3. Tried using different USB ports
4. Tried different USB cables
5. Uninstalled n reinstalled USB driver, adb n fastboot, qpst, n miflash many a times along with restarting my PC.
None of the above helped.
I think, if eMMC software download starts displaying COM20 Phone connected, then the issue might be sorted out.
Kindly assist.

Kindly assist.

U need ufs flash not emmc. Change programmer in qfil.

I have a some experience with miflash but I use it for xiaomi . I've never flashed my zuk z2 pro by miflash . If you want to use miflash use 2016.03.30 and run it on PC with win 64 . Create a folder on c: for example "zuk" and copy to that all contents of unrar Qpst/Qfil zui rom . If you have Qualcomm hs usb 9008 that means your phone is in edl ( download mode ) . Good luck

I appreciate all ur support....
As suggested, tried Miflash 30.03.2016 also. This ones showing class not registered.
No of things i did to overcome this errors.
1. Changed my PC to developer mode. Allowed portable device connections n stuff.
2. Visual studio C++ 2010 was installed along with Qualcomm driver, i believe thats sufficient.
3. Disabled my Firewall.
4. Downloaded n copied some atl70.dll file to my syswow64 folder as well as sys32 folder.
Tried all flash tools again after these changes....Same negative results.
Any further advices !!!
Regards

It's fault of drivers . Go to device manager and chose qualcomm hs usb 9800 and update driver automaticly . The second matter concerning of flashing by qpst/qfil - why did you put rom in qpst location ? . It must be for example on desktop in one folder . The simplest path is better . Don't use spacebar . Load content you must chose from that rom . Don't use other location . It's not necessary . Could you give some screenshots with qfil errors
