No luck. I tried in 4 different pc's with windows xp, 8 snd 8.1 but every time emmc download freezesband after ehile phone restarts… i will sent it back in merimobiles, maybe they can fix it…

Thank you anyway…
[Lenovo Vibe Z Guides, News, & Discussion] camalon!:
Hello camaew: I tried something may be useful, if you hold vol- then plug usb you will see flashing red led or solid red led (don't worry - still holding until the mobile vibrate) if it takes 5 minutes don't worry, then the logo appears leave vol- & any keys, leave the mobile about 15 minutes plugged (like charging) & then try to unplug it & then you can get blue led for 10 minutes, try & tell me:o

QPST recovery for Lenovo k910e

Hi ,

I managed to partially brick my Lenovo K910e by wrongly installing TWRP for 4.4.2 on a 4.2.2 operating system.

My only option left is to use the dreaded QPST recovery tools.

After many hours I think I am on the verge of recovering the phone , except for one last frustrating step.

In eMMC Recovery tool after following all the steps , with every thing displayed as should be , I cannot get the "download" button ( at the bottom left of the screen ) to highlight , so I cannot start the download.

I have supplied the screen shots , is there anything I have missed ?.View attachment 3046662

Did you check load XML and load patch files first?

If you did and still didn't get that, try unchecked program mmc and check program boot... And choose files

[Lenovo Vibe Z Guides, News, & Discussion] buzzbuzz1:
lenovo k910e

Thanks for your advice.

Yes I did check the "load XML"_option first .

I have tried it with your second suggestion by unchecking mmc and check program boot files and the download button did work but not a lot happened the download process didnt really kick off.

Have I loaded the bin file in C:\ the correct way?.

I created a new folder , named it " bin" , unpacked with 7 zip the K910 qpst file , opened it cut and paste all the contents to the bin file.

Then I opened the flash local xml file with note++ and changed the bin directory to C:\bin\MPRG8974.mbn. then clicked the save .

Is this correct , the instructions were a little vague when it came to this step.

My phone is in a semi bricked state with blue LED so I am only trying to recover from step #9 (#5 post)
[Lenovo Vibe Z Guides, News, & Discussion] Crowds:
If the path is c:\bin\ than yes.

You should put the path where the file is.

If you got a blue LED and a 9006 you should be able to restore it from 9th step. If you couldn't try from 1st.

But the hardest step is between 8th and 9th steps.

I have just tried installing from the first step but the phone remains recognised on com port and does not drop down to being recognised as a USB connection ( phone does not loose a connection ).

I have a corrupted TWRP recovery for 4.4.2 on a 4.2.2 phone , do you think this could be causing problems.

Hey man, this is also my main problem, as you see (not writable), what can we do, some help, i tried (disk genius) but can't also format "sbl" partition, whats up crowds?!

Not writable or not ready ?.

I tried MiFlash from post #96 (page 10 of this thread ) and seemed to actually getting some where until I hit error 0x800700021 ...... 0x000000004000000.

If we can figure this out it may lead to a result.

I have been chasing my tail in eMMC for days now without luck , nearly 45 hours this week on this damn phone.

I'm using Windows 8.1 , 32 bit system.
[Lenovo Vibe Z Guides, News, & Discussion] camalon!:
i tried to use MiFlash under xp 32, successful but nothing happens, i tried qpst at "7-32, 7-64, xp-32, 8.1-64" no news.

i think there were a mistake or another tool to flash it, but it's not yet :o, waiting & trying.
[Lenovo Vibe Z Guides, News, & Discussion] buzzbuzz1:
Has anyone figured out the error code in MiFlash 080070002.

I actually started to get a download happening until the error notification.

My specific details are ,

TWRP worked for several reboot's then somehow become corrupted and is now stuck on TeamWin splash screen ( flashes on and off every 4 seconds )

Partial unbrick

Hello! I succeeded to revive my Lenovo K910 dual sim WCDMA, with QPST method, but now I have 2 big problems.

I lost both 1st IMEI and MAC address. (I think as a consequence of this) my phone keeps rebooting every few minutes (or seconds). How could I solve???

P.S.: I can recover the IMEI number on the phone box, but... Where could I find the MAC address?

P.P.S.: I saw that IMEI are saved inside a folder called EFS. And there are several apps that backup and restore these folder, not to lose these precious data. Now: for who (as me) has lost these data, is there a possibility to take an efs folder from another K910, change the IMEI inside the files, and put these files on the broken phone? Thank you.

Here an extract from logcat:

E/MSimSignalClusterView( 9492): main data = 0

E/MSimSignalClusterView( 9492): subscription = 0, mMobileVisible = true, mDataVisible = false, mIsAirplaneMode = true

E/MSimSignalClusterView( 9492): mMobileActivityId=0

[Lenovo Vibe Z Guides, News, & Discussion] buzzbuzz1:
lenovo k910

I'm as frustrated as you are .

Three computers later and still the same error messages.

Makes me think it could be the way I'm installing the drivers.

Could someone make clear the exact steps to install the drivers . When the drivers file is opened which of the files should be installed and in any particular order.

In the XP & Win 7 file there are two sub folders "checked & free" with installation files.

Do these need to be installed ( I'm using 32 bit computer ) or just the QC_Dload_driver file.

Thanks for any advice.

Hello i have the same problem with my k920 no boot no screen only blue led light when i connect the usb.In device manager is found as qualcomm hs-usb diagnostics 9006 (com13) everytime i connect it to usb.Is there any chance to bring it back to life with qpst tool?I cant not flash it as the qpst tool dosnt recognise the phone inside the com list.I checked the progamm mmc and checked the phone on the driver list but the download button is grayed out.Is there any way to roll back the phone and get recognised as hs-usb qdloader 9008 so i can flash it again?
[Lenovo Vibe Z Guides, News, & Discussion] buzzbuzz1:
Agggggghhh!..... I've tried every way for a month now to unbrick this brick from its blue light 9006 apparently easy to recover from state.

Different drivers , different computers , complete system reformat , QPST , MiFlash , remove the battery but no luck.

I get close on a windows XP 32 bit computer but no cigar.

I've tried standing on my head , holding my tongue left and right but still no luck.

The words "from the 9th step 5th post" are burned into my memory and starting to give me psychological episodes

I'm flying an African witch doctor in next week so he can dance around my phone and cast some serious magic over it.

But ! If any one out there has any suggestions ....any! , please let us all know.

I have left the phone connected to the computer for some time hoping it may auto boot , but no luck.

I've tried the to reboot with the phone disconnected from the computer but no luck there also.

Is there something I have missed , any help is really appreciated.

Have you managed to figure it out.

[Lenovo Vibe Z Guides, News, & Discussion] buzzbuzz1:
miflash

I have succeeded to finally get miflash to run the file to the end . But it still doesn't boot into recovery.

The only way I have managed to get it to run past the error you are encountering was to use Windows XP running service pack 2 with zero updates. Download miflash and run , and I found only the Qualcomm 2006 drivers worked ( not 2012 drivers ) , no others.

Tried several computers running 8.1 and Windows 7 but only XP worked.

The bug I'm encountering with miflash is , once closed then reopened it will not work and returns the same error you encounter.

Simply uninstall miflash then reinstall and it works as it should once more.

Try your best to get your hands on a fresh reimage XP computer and good luck.

Just to repeat , in my instance anyway , even though miflash completed the download and returned a successful, task completed message it did not do anything. My Vibe Z K910e is still bricked in blue light download mode.

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:

a) http://xdaforums.com/showpost.php?p=55796909&postcount=2

b) http://xdaforums.com/showpost.php?p=55796912&postcount=3

c) http://xdaforums.com/showpost.php?p=55796917&postcount=4​

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

Bricked Lenovo A6000

Hello I have bricked my 30 Days old lenovo A6000

Please help me to unbrick it
[Lenovo Vibe Z Guides, News, & Discussion] DreamsKnight:
successfully restored! and only few hours of work :D

as always, at the end is everything more simple.

1-install a fresh win 7 x64, this is important for right drivers

2-download all the files provided by the thread starter

3-download also this one of two post before CLICK

4-click start, write cmd in the search field, rightclick, run as administrator. in the console write

bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS

press enter

bcdedit.exe -set TESTSIGNING ON

press enter

reboot. now you have permanently the driver signature check disabled.

5-install the first qpst, provided by the thread starter. after this install the second one in the same folder. reboot.

6-

unzip the driver.zip provided by the thread starter.

power on the phone holding down together vol+/vol-/power. you will see black screen and blue led. connect to pc. you have in device manager the exclamation mark and a device QHSUSB_DLOAD or QHSUSB_BULK

force the installation of this driver (my os is italian, i try to translate the concept): right click, update the driver, search the driver in the computer, choose manually, all hardware, disc driver ...

now point to the folder previously unzipped: driver/Win7_64位/qcser.inf

choose qualcomm HS-USB QDownloader 9008

ignore the incompatibility messagge, press ok.

now the driver must be installed. reboot, check if the phone is recognized as " qualcomm HS-USB QDownloader 9008 (COM X)" (x= a number)

let the phone connected in this way.

7-

Unpack the Lenovo QST File that you download from 3rd post [K910_1_S_3_2144.1_0040_140219_qpst.7z] with 7-Zip

rename the folder bin.

move the folder to c:\

now you must have c:\bin\ all the files inside

Inside bin folder you'll find flash_local.xml file. Open it with Notepad++

modify the image_path field as c:\bin\MPRG8974.mbn and save.

8-

run QFil (is part of qpst program)

the com port must be qualcomm HS-USB QDownloader 9008 (COM X), if not choose this one.

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

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

unplug the phone, power off the phone.

obviously, now the com field is not recognized

9- now: you need three hands, call someone. this is not a joke.

one people must be ready to see the com field. when he will see qualcomm HS-USB QDownloader 9008 (COM X) he will have less than one second to press the download button.

the second people must plug the phone to pc holding vol+ (THIS IS NOT AS BEFORE!!!!!)

as said, only one second to see qualcomm HS-USB QDownloader 9008 (COM X), press download. wait until you'll have the langauge choice in the phone. :fingers-crossed:
