Cannot get past step 1 here

This is where the hard work begin yet with it you might...just might, bring your phone back alive again. :good:

Important Notice:

Like i wrote before, i held no responsibility from now on if your brake your phone for life
If you managed to connect your phone to PC in the proper way (post #4) you're good to go. :cyclops:

Before we go deeper on "Step-by-Step Instructions" we need to configure just a couple of things first.

1. Unpack the Lenovo QST File that you download from 3rd post [K910_1_S_3_2144.1_0040_140219_qpst.7z] with 7-Zip
2. Move the bin folder to PC root [C:\]
3. Inside bin folder you'll find flash_local.xml file. Open it with Notepad++
4. Configure this way
5. 
6. Now you're finally ready :highfive:

1. Step-by-Step Instructions

• Open Device Manager and QPST Software from installation folder
• Connect your phone to PC through USB extention cable
• Check if Device Manager sees your phone properly
  
  
  
  
  and QPST to
  
  
• If everything's ok open eMMC Software Download. Now do the following:
  
  1. On Sahara XML file, put the path where the flash_local.xml file is (the one you edited previously).
  2. In Flash Programmer file name write MPRG8974.mbn
  3. In Boot Image write 8974_msimage.mbn
  4. In Load XML def... choose rawprogram0.xml file from explorer
  5. In Load patch def... choose patch0.xml file from explorer
  6. Uncheck Program MMC device
  7. At this time your PC no longer sees your phone at COM Port but it had changed to Lenovo USB something. Connect your phone to PC through USB extention cable again with the right key combination
  8. Right after you inser USB cable start pressing ENTER key on your PC like a maniac. This is the secret. You had to click it at the right time in order eMMC Software Download starts the download process.
     --- Again. This is the most stressful step of all of this. Try not to brake your PC and in an act of despair don't crash your phone against the wall ---
     In order to do the above i had to wipe all my PC after spend an entire month without results
     If you received any message regarding your disks or format choose NO or CANCEL
     
     Finally you've made it, let's go further
  9. Uncheck Program Boot Loaders
  10. Now check the Program MMC device
  11. Choose your phone from the list of drives
  12. Click Download again
  13. When the process ended remove USB cable from PC and reboot the phone.
      
      Nothing like an image to explain the above steps, right guys? :laugh:
      
      

Hope this help you anyway :good:

IMPORTANT:
If you ended with a phone without vibration, led or anything that means that you "kill" the battery. In that case you have to proceed in another way because your phone will never boot and you won't be able to start nothing.
Check next post if that is your case

Firstly, thanks for such a detailed tutorial for fixing a bricked lenovo k910.
On the other hand, i can't get past step one simply because, it shows my phone as preloader only for a few seconds then it change to: E:
MTP USB Device
it will not stay as a com port no matter what i try so its not visible in qpst.. Any ideas will be much appreciated

lenovo k910l

hi Crowds, please help me. lenovo I k910L stop at the logo. when pressed on, vibrate and then logo, vibrate again and logo. but when in press volume up and volume down my lenovo enter into fastboot mode. please help me, what should I do.

 

[yuganta]

Is flashing of Lenovo K910L is same process as K910

 

[joidiple]

hi sir, i have same problem with my lenovo vibe z K910L, i updatd it via ota but got an error in that update, now phone is stuck in lenovo logo and stock recovery, phone is all stock not root. can i use qpst? i can still boot into stock recovery. i tried adb sideload but got error "wrong footer and signature verification failed"

 

[Crowds]

Hi all

First of all, sorry for beeing away for quite some time but my profissional life its completelly crazy.

Secondly, i don't own my k910 anymore. To be honest im very disapointed with lenovo itself cause since almost a year they don't release a firmware update. I don't think this is a way of doing business. And for the last, i'm algo very disapointed with the quality of the phone as a whole and with the screen in particular.

For all of those with problems using QPST,well... That's another lenovo problem as far as i saw it.
Its a complete nonsense what alll we have been through just to get this s#-*y phone get back alive.
My opinion?
Try, try and try again...you will win sooner or later

Again all of you who expect my help but...that's life

[gerstavros]

Images in the tutorial are no loading, probably are removed from server. Anyone know at least what changes to do in flash_local.xml? The path of file?
Also i dont understand the step 8. Pressing Enter at that step just opens and closes the QFuse window.
