For all "bricked phone guys": I have here a K910 Mainboard left over from experiments. Probably I changed all main parts until I found out my battery was defect *lol*. So I'd buy the Mainboard and don't need it.

Root, unlocked, okay, actual with 4.4.2 System. If you want, I can put the board into your phone and update it to Lollypop 5.1.1. - my phone is working perfect with it. ;)

I am from Switzerland, price will be 70CHF + shipping + a cold beer for changing the board (if you want to have it done).

Admin: if this (selling) is not allowed here, delete it. I only want to offer this here for board members who need one, before I put it into an public auction.

Hi there ,

I brick my phone when i execute the bootloader unlock file. Can I get some guides over here? I have been searching all around the internet, yet i still stuck here.

The QPST configurations on the state showing a green bar. I left it for the whole night , It still showing the green bar. It doesn't move at all.

=( i am out of idea. '

FYI :

My device manager is showing HS-USB QDLoader 9008

Hello,

I brick my phone two day ago trying to install Team Superluminal cyanogenmod 12.1 ROM for Lenovo K910 and TS TWRP recovery. My phone was dead no OS and no recovery (when I turn on phone only the logo appears)...

Then I found Crowds solution for Lenovo k910. I managed to unbrick my phone with QFIL.

Thank you
[Lenovo Vibe Z Guides, News, & Discussion] CCCPPP:
Hello,

I just revived my K910. So, my advice is:

1) Disable driver signature blablabla

2) Install QPST

3) Plug the K910

4) If you see the mode "9006 or 9008" just uninstall

5) Now, install the drivers provided in the tutorial manually

NOTE: IF WINDOWS SAYS THAT the driver could not be installed, disable the driver sign..blablabla again and try to install the driver

BTW, I used the ones in the folder "QC_Dload_driver".

At this point, you should see the mode 9006

6) Proceed with the tutorial

Note 2: I didn't do any crazy hitting button step. I got my k910 in the third day of trying, so keep trying! :laugh:

If you succeed, you be stacked in the Lenovo logo, then use the sdfuse method to install a new rom.

Can you please help on this. I was trying to flash the K910 with both known methods over eMMC software download tool and MiFlash. Thing is i successfully finishing the flashing process but in the end when i try to start the phone it shows Lenovo logo and starts bootloop. It vibrates turn off, turn on to lenovo logo and in 2-3 seconds same thing, infinity times. Same thing happening after truing the procedure with both flashing tools. I do not know why the phone cannot start normally after the successful flash procedure.

Things i've done so far.

- Add port to configuration tool (device manager detects as 9008 mode)

- download MPRG8974.mbn file to phone

- After that phone is recognized in 9006 mode

- After successful flashing all files in the end (i don't know probably it should be like that) it opens 5-6 removable partitions, only one is accessible and for the rest it gives me format now. Im canceling that.

- Unplugging the phone and when i want to turn on usually is blocked so im removing the connector from the battery. After that phone turns on but still same bootloop.

- Same thing is with MiFlash tool just in the end did not gives me that removable partitions but it says Operation completed successfully. But again bootloop. Please tell me what is going on here. Why my phone won't start after completing the procedure.

last step

Hi everyone,

i'm in the last step of this never ending tragedy! :D

I' can't explain myself why k910 power off after one seconds in download mode with cable pluged in.

I read the entire thread and Crowds is right. You have to make every single step with calm and so I was able to reach the last step.

But now i'm stopped too.

Does anyone has ideas?

good news guys!!! :D:D:D:D

k910 reborn!!!

Here is (hope to help someone): unlpluged battery connector, pluged in cable with volume+ pressed, after vibration repluged battery connector.

Revived.

I have no words for this.

Maybe problem with battery :rolleyes:

any advice ?

i try to follow those steps, and my pc is finding vibe z as a Qualcomm HS-USB... and it load com in QPST, but only for while, my vibe z is switching itself into MTP USB device.

How to connect to have the Qualcomm driver stable?

How it should look? should i be able to enter adb commands in fastboot mode? they are enable only when phone is in recovery mode.

Thanks for reply.

Hi Crowds! this post is very informative.

My question is where or how to obtain QCN files? ( those files needed for eMMC Download Tool.)

I bricked my Sony XL and its already detected as hsqdload in my pc. I just need the mprg and mbn file.

Please enlighten me with your great wisdom.

K910 Bricked

I hope someone is able to help me.

I bricked a K910 while trying to change it's ROM. I used Crowds tutorial but I forgot to unlock the bootloader and executed flashrec.exe directly after rooting. It's already out of battery, so this is the current phone behaviour:

- Any key combination + USB to PC = Vibrates, No LED, No Image on screen. Can't go to recovery. It isn't recognized either by adb or fastboot in any Operating System.

- PC (Windows) - detects it as Qualcomm HS-USB Diagnostics 9006. Several drives/partitions show up. Most are not supported by Windows, so it asks to Format them., only one is accessible.

- PC (Ubunty 14.04) - running the command lsusb returns the device: ID 05c6:9006 Qualcomm, Inc.

5 Partitions are accessible (4 of which are EXT4, and one is msdos format, the same one accessible in Windows)

Now the weird part:

- MiFlash - Apparently flashes the ROM correctly, no errors. Produces no change on the phone.

- QPST Configuration - The green bar, in the State, only goes about halfway.

- eMMC Software Download - Phone restarts constantly, in a loop. Can't get it to Download Mode. Can't Program Bootloaders or MMC Device. The Qualcomm device, though detected, is not writable. It times out after a short while.

- Tried other tools like: EMMC_DownLoad_V1.2.4.exe - Similar behaviour to Miflash. No errors. Flashes but the phone stays bricked.

Tried to check for partition issues. Parted Magic didn't find any. What bothers me is, since I have full access to the phones storage in Windows, wouldn't be possible just to save the correct files in there, just by copying them, or am I tripping?

Can anyone shed a light, please?

Thanks guys. :)

Cannot get past step 1 here

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 Vibe Z Guides, News, & Discussion] 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 :D

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