If this was useful in anyway just click "thanks" button and "Rate" this thread.

I won't held any responsibility if you broke your phone for good! This is based on research and on my own experience. This is just a guide who exists to help you.

Ok, after i bricked (?!) my Lenovo K910 and recover it from dead only after 1 month(!!!) and after receive a few messages i left you with my Step-by-Step Guide of how to use QPST Tools to recover your dead phone.

Important Information

History
To make it short i bought this in August 26th and on 27th i completely broke my K910. I was only able to recover it by September 26th!!!
It was so broken that i ended up with no vibration, no LED, no nothing. It's seams that i send my money to trash or at least a hugely expensive paperweight :laugh:

After searching for a solution in web sites as diverse as Chinese, Romanians, Indians, Russians, Spanish, etc. etc. i've found one in particular in HTC Mania Spain written by corion witch i thought...that could be it!!! :highfive:

Wrong...I've follow all the provided steps one-by-one but nothing.
I had tried virtualize Windows since XP version. Nothing seams to work until...on a rare and brilliant occasion ... :angel:


So...Let's cut the crack and let's go with it.

The following steps where the ones i've followed. This was based mostly on corion's tread in HTC Mania as described above plus my own experience witch i think make some difference and lead me to recover my phone.

Finally there's one thing that's hugely important and that is lots and lots of patience :D

Pré-Requisites

Based in my experience and after i try this on my Win8.1 without success i try all the following steps. All of them unsuccessful.

  1. Virtualize Win XP 32-bits & 64-bits
  2. Virtualize Win7 32-bits & 64-bits

You can imagine my patience and hours i've spend installing all those Windows OS and all Microsoft patches :eek: most of all because my laptop is my professional one so i couldn't just install a new copy :(

After all those frustrations, in a act of despair, i decided to clean completely my laptop and pray that i could recover my work lately. This was the most wisely decision i've made after 1 month!!! So...


  1. Pre-Requisites*
  • Format your PC;
  • Install your OS from scratch;
  • Apply all the patches from Microsoft;
  • Buy or get a old USB cable extention** from someone.


Notes:
* Again, this is based on my experience, you may try all the steps without format your PC. You had nothing to loos atm.
** In our days USB cables transfer data in a very high rate so the idea of using an USB extension is to slow down a little bit transfer data between Phone/PC. Older the better. We going to need this as you see ahead in post #5

Kind Regards

1. In order to recover your Lenovo K910 you must follow this steps one by one so read carefully and please don fill this thread with questions already answered here.

2. Like me, if you take 1 month...take it. If you take 20 minutes...great but please don't ask over and over the same questions. :highfive:

3. If you had any questions regarding tech common sense use my dearest friend here

4. If by any chance you really broke your phone, it's your fault! You're the one who lead to this, not me!


Installation Procedure

  2. Reboot your PC with "Disable signature verification of digital controllers" checked
    Read point 3 from above hidden text
  3. Open Device Manager
  4. Connect your phone to PC through a USB cable pressing VOL-
    This is where you going to use the USB extension cable written above. Try another key combination if this one doesn't work
  5. By this time your PC began searching for the correct drivers. If everything went ok, device manager will see android phone as QHSUSB_DLOAD or QHSUSB_BULK with an exclamation mark. If not try again,
    --- If VOL- doesn't work try several combinations, like VOL+/USB cable or VOL-/VOL+/USB ---
  6. Install the drivers (not Lenovo ones) manually from the drivers folder you've just downloaded (Install accordly to your OS version)
  7. Your Device Manager should see you phone as:
    jbkzNKKi8QqhuM_xs.jpg

    Doesn't matter if it is COM10 or another
  8. Reboot your PC with "Disable signature verification of digital controllers" checked
    Read point 3 from above hidden text
  9. Install Lenovo drivers
  10. Reboot your PC with "Disable signature verification of digital controllers" checked
    Read point 3 from above hidden text

Now continue to the next step on post #5

[Guide]How To Recover With QPST

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. jbvpzvkaiUn1iw_xs.jpg
  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
    jbkzNKKi8QqhuM_xs.jpg


    and QPST to
    jbdRBiYwCzG57L_xs.jpg
  • 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:
      jVDGa0kFv6tgt_xs.jpg

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 ;)

No Vibration, No LED, No Nothing? Don't Worry, Here's a Solution

Isn't Android Mobile Phones wonderful?!?!

There's a solution for almost everything :laugh::laugh:

Description
You've ended with a complete dead phone because you've spend to much time playing with it on previous post.
The good thing is that your battery is just in a 0% stage so what should we do in this case? Lenovo sell this like a non-removal battery, how the heck i solve this tricky situation?!

Solution
You must be thinking "how stupid i am for spending money on a non-removal battery phone" well... it is removable!!! Check how to do it here. At this video it's only shown how to get to the battery. You must disconnect it.

Now you can go back to post #5 and follow the provided steps :silly:

Kind Regards
Crowds

Hi Crowds,

when I install the QPST driver the phone is seen in device manager same as your picture. I can then see the COM port in QPST configuration but it says 'No Phone'. Once I install the Lenovo drivers and reboot the phone is no longer available in the QPST configuration at all. (Sorry to take more of your time, I did try to Google this but have not found anything.)

Hi RASTAS12 ;)

That's a very, very common question
You're at this stage of post #5
[*]Uncheck Program MMC device
[*]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
[*]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 ---
Like i wrote, you had to have very patience atm and when you loose COM Port you should disconnect USB cable and try again
[*]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.

    I had tried virtualize Windows since XP version. Nothing seams to work until...on a rare and brilliant occasion ... :angel:

      --- If VOL- doesn't work try several combinations, like VOL+/USB cable or VOL-/VOL+/USB ---
    6. Install the drivers (not Lenovo ones) manually from the drivers folder you've just downloaded (Install accordly to your OS version)
    7. Your Device Manager should see you phone as:

    [Guide]How To Recover With QPST

    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. jbvpzvkaiUn1iw_xs.jpg
    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
      jbkzNKKi8QqhuM_xs.jpg


      and QPST to
      jbdRBiYwCzG57L_xs.jpg
    • 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:
        jVDGa0kFv6tgt_xs.jpg

    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 ;)

    Hi,

    It is solution from polish forum: http://forum.android.com.pl/topic/222097-lenono-k910-how-to-unbrick-hard-bricked-solution/

    I am not an author of this, but i hope darek9009 will be not angry that I share this. Using this solution I unbrick my K910.

    This way of fixing is mix of solutions provided by Crowds, from some russian forums and polish forum.android.com

    I hope it help many persons who have problem with appearing Qualcom device for only 3 sek, so many person are unable to use QPST for unbrick.

    Solution:

    1. You have to make three instructions provided by Crowds:




    2. Now we have to download this file : https://cloud.mail.ru/public/bf8965b252e2/QPST_2.7.422.7z

    3. We have to install now new version of QPST in the same folder where we have older version of QPST

    4. We have to run QFil

    5. To Programer Path we have to choose: prog_emmc_firehose_8974.mbn (we should have this in QPST folder if we prepare everything properly)

    6. Next we click Load XML and choose: rawprogram0.xml and next we choose patch0

    7. Lenovo have to be turned off.

    8. Please put vol + and connect Lenovo to PC

    9. When Lenovo appear in PC (like a Qualcomm) you have to fast click Download

    10. PC should start flashing Lenovo and load new firmware.

    11. Please wait until Lenovo restart. And now:
    a) If your battery was disconnected beacuse was discharged you have to diconnect Lenovo from PC, put vol+ and connect again. In logs in QFil you should see Finish download. Now connect your battery and connect charger. Please wait when you will be able to turn on your phone. (when battery will have some power)
    b) If your battery was ok and connected Lenovo should restart and start working properly.



    I hope it help someone with unbricking his phones.

    I won't held any responsibility if you broke your phone. This is based on research and on my own experience. This is just a guide to help you.

    Regards,
    Bart
