UNBRICK no.1 x2 using original ROM

Thanks for this, i now have access to the ROM, and if you can understand the instructions its possible to install the ROM again.

I just did this today, however its partially rooted, as was my phone when I received the X2.

I need to now try to use kitchen and a bunch of other tools as described here to try and install Su and/or root the rom: en.miui.com/thread-21539-1-1.html

if i am sucessful i will post instructions, for now here are clear instructions on how to (should work as tested on my x2) unbrick X2 with this software.

1. download this: "ht tps: SLASH SLASH drive DOT google DOT com SLASH file SLASH d SLASH 0ByeMRyNUHsNRdGc0Qk1jQlJIb3c SLASH view" (i have less than 10 posts so cannot type full url, replace SLASH SLASH with // and DOT with .)

2. extract the rar (download trial of winrar or similar to extract (noobs))

3. launch the setup.exe from the folder you extracted too. (remember where it is installed)

4. extract the X2.rar to a folder (new folder on desktop or my docs)

5. right click (win 7, 8 10) and run as admin (the installed program from desktop called "QMSCT")

6. open the "setup" menu in QMSCT and click "configuration"

7. make settings look like the picture in: "ht tp s: SLASH SLASH drive . google . com SLASH file SLASH d SLASH 0B2M8OmUI5XS-SGtudHYwS0tLZGc SLASH view?usp=sharing"

all check boxes and fixed options must be identical, i have highlighted red

8. insert (red again) the file names shown in the picture (they will be in the original extracted rar where you launched the setup program or in the directory you installed to).

9. in the bottom field locate the folder where you extracted the x2.rar, this folder location is the folder you must browse to and select in the bottom of the settings screen. Only care about the red markings i made, i will now tell you below how to get the information you cannot change yet in the settings.

10. first SAVE, exit the settings, then exit program.

11. plug in no.1 X2 Mobile, while phone on hold power until options appear, then hit restart, before it turns off and vibrates, hold down both volume buttons and then also press and hold power... do'nt let go until phone vibrates and turns on to a blank screen... sometimes it will restart, just do it over again and again until it boots up blank (screen has lit up back/grey)

12. when screen blank windows will install driver. NB: Unfortunatly i had issues here and it took a windows 10 tech preview install 10041 build x64 to do this, however it did not get fiddly i just had to try xppro, win 10x64 on a laptop and then my desktop to work it out, also I was following chinese instructions that had been translated and were not perfect to begin with. So any win 7, xp or 8 might need to source which driver to install from no.1. Windows 10 tech preview is free and can be put on another partition easily if you search (noob) on xda or google i am sure someone will have covered it.

13. unplug phone, launch QMSCT again as admin, go into settings and click "Start setup process" then click ok on dialogue box. now plug in phone and hold vol buttons again, then power and hold all 3 down until it reboots into the blank screen. if all works a port will be found (1-8 i think i saw in my many attempts) once it has found it and you see the information on the screen look similar to my screen shot, click on save. note your port will maybe differ, and if it does not work, restart application and phone again and repeat. when it saves, exit configuration, exit application and then you need to restart application

14. if all is right, plug in phone, hold the 3 buttons in order again, and the application will start flashing it. DONT UNPLUG UNTIL RED OR GREEN shown in app.

RED=fail - go back through my instructions and the supplied "flash tutorial.docx" in the RAR (you extracted this at the begining - the pictures may help more than the instructions they gave)

GREEN=Woohoo! all done, unplug phone and do the power button combo, it will restart (might need to do combo a few times)

NB: settings stay the same once this application is set up, so you do not need to go through all again in future, just launch app and then plug in phone and do 3 button combo.

I hope this helps, if you are good with CUSTOM ROM creation, feel free to see if you can get this rom rooted and flashed and tell me/readers of this forum... if anyone wants a real challenge, root this rom, make the kernal 64bit and not 32bit and then post here.... this is what I want to do eventually if i can work it out.

good luck any bricked x2 owners
