if you're receiving !"sahara xml file path not valid" it' s because you didn't put the correct path on flash_local.xml file (point 4 f 5th post) or if you had changed, did you work with Notepad++?

Try change port, don't know.

My tutorial reflects my own experience. I've tryed several things along one month and nothing work except, like i wrote, after a complete fresh OS installation. Why?! Don't have a clue

sir correction done
[Lenovo Vibe Z Guides, News, & Discussion] jhonmer:
I will do that. I kept it as my last resort. I have tried all the methods, even with MIflash on a Windows XP and I succedded to finish successfully but without success :((. I read that a user from Indonesia was in the same situation as me and you didn't know what to answer him. ( please don't take it as judgement about you - I thank you for all the help that you given to me.)

Please tell me what OS do you use ? Are there any other methods left ?(without QPST or MIflah?
[Lenovo Vibe Z Guides, News, & Discussion] Crowds:
Like I've wrote I've tried all OS versions and also MiFlash.

The only way I was able to be succeeded was only after a fresh and clean OS install. In my case I was able to flash on Win8.1
[Lenovo Vibe Z Guides, News, & Discussion] cellbuster21:
sir reinstalled the os

done every thing

dont know what to do now

is there any other method besides qpst
[Lenovo Vibe Z Guides, News, & Discussion] Crowds:
plain and simple?

No, unfortunately no.

Keep OS clean and continue trying that't the only thing you could do atm :( sorry

I know that's frustating but...
[Lenovo Vibe Z Guides, News, & Discussion] RASTAS12:
Hi Crowds, I have tried XP, Win 7 and Win 8.1. I always manage to get the 9008 driver installed but QPST will not see any phone. Do you have any idea why? (I have tried to press all possible key sequences when starting the phone too.)
[Lenovo Vibe Z Guides, News, & Discussion] Crowds:
Hi;)

By the time Device Manager sees the phone as Qualcoom, QPST as to see as well. You should see a green bar in state column.

The key sequence is exactly the same as device manager sees it. If device manager see it as qualcoom QPST has to see.

If you still struglin' with that, witch i think its strange, try to remove lenovo drivers (not the ones provided in the drivers folder by me), reboot and try again.
[Lenovo Vibe Z Guides, News, & Discussion] cellbuster21:
in emmc

i am getting this

device mode =sahara on port 10000

is it normal???????
[Lenovo Vibe Z Guides, News, & Discussion] cellbuster21:
urgent
[Lenovo Vibe Z Guides, News, & Discussion] Crowds:
Like i said. The only thing you could have is patience :D

Ofnyou dont have that theres only other 2 solutions:

1. Send it to warranty

2. Buy another phone

Unfortunately with bootloader locked this is the only solution.

Make sure you follow everything as i wrote and...there's no need to write how, why or what.

There's no other way.

[Lenovo Vibe Z Guides, News, & Discussion] Crowds:
I assume that you've unchecked "Program Boot Loaders", select correct drive...did you put all files in the correct place (flash local.xml and so on?)?

If you correctly put everything in the right place maybe qst files are corrupted (?) try dw again
[Lenovo Vibe Z Guides, News, & Discussion] dmarghe:
i try all solution, i select correct file, i correct with pad the correct driver. Only one solution i don't test: reinstall the os in my pc....because i try in 3 pc and i have the same effect: when i put my phone in recovery mode, the led blue is on, the qpst config start and find the phone, the green line start, i open emmc program, select the correct file and i start download, but i have the same message and after 30sec when the green line is full, the phone restart with lenovo logo and stop here. pc stop when write patch for select com port ""
[Lenovo Vibe Z Guides, News, & Discussion] Crowds:
That's one of the tricky part :)

You're making everything alright just had to find a way to install com drivers right after bulk appear.

Try uninstall lenovo drivers in order PC takes time to search for those drivers in particular. That should give you more time to install com driver
[Lenovo Vibe Z Guides, News, & Discussion] Dubster93:
It happens exactly the same. I appear like 5 or 6 disk and asks me if I want to reformat and I give NO. I have read and done the tutorial about 10 times, as it says, and nothing. Also probe with MiFlash (Seergio method, HTCMania) and not spend more than 4 seconds. I'll keep trying I 32bit Windows XP, I tell them to see how I was.

Please help me...

Hi bro, I'm new user from Indonesia, I got my phone brick.. it can't boot on to TWRP bootloader neither use fastboot (even i can't recover it by using USB OTG cable) .. the only think i can do is install firmware (ROM) from command prompt via adb sideload, i've download many ROM but it always fail on signature verification.. (my device is K910L Single Sim no card slot)

I've been searching official ROM for my device,, i wonder if you can please to help me to share ROM which name is K910L_S216_140704-qsb_user_1407041641

ps. i've been trying K910L_S129_140402, K910L_S214_140523 but they fail on signature verification..

sorry for my bad english.. I'm very thankful for your help..
[Lenovo Vibe Z Guides, News, & Discussion] Crowds:
Here you can dw S216 firmware.

Download and extract

Create "sdfuse" folder (without quotes and ")

Copy qst file into sdfuse folder and put it on usb drive

Connect through OTG cable

Enter in recovery mode by pressing Power & VOL- at the same time

Release Power button when feel vibration keeping VOL- pressed

Release VOL- button when Lenovo Logo appear

Select "Update SD"

Wait till finish then reboot

Hope this helps ;)

God luck
[Lenovo Vibe Z Guides, News, & Discussion] donnyadhi:
I have tried to download this ROM on the link from firedrive before, but always fail and only pop-up ads kept out.

My apologize for not explaining the condition of my phone before, I do not know why when failed updating my ROM, I can not get into recovery mode menu (by pressing the Power & vol-). I can only go to the "android system recovery <3e>". Therefore I can only use the ADB sideload to copy the ROM into my phone.

I really need help and assistance from you. I am very grateful for your help, I hope I can return the favor for all you have done for me ..
[Lenovo Vibe Z Guides, News, & Discussion] Crowds:
If you have access through adb try the following:

Copy TWRP recovery.img into device through adb

adb push xxxxxxx.img /sdcard/ (where xxxxxx is the img file name)

then

adb reboot-bootloader

then

fastboot flash recovery

By this time you should be able to enter in recovery mode again and install any zip file

Regarding other qst files i don't have a clue where to get it...sorry and good luck ;)
[Lenovo Vibe Z Guides, News, & Discussion] donnyadhi:
That's the problem, i can only use sideload parameter while using ADB on command prompt, via "apply update from ADB" menu in Android System Recovery, eg. adb sideload xxxxx.zip|qsb|7z|img

until i found the very official ROM for my phone, i always stuck with "E:signature verification failed" message :crying:
[Lenovo Vibe Z Guides, News, & Discussion] Crowds:
Did you unzip were the qst file was?

You should heve a bunch of files inside a single folder unziped
[Lenovo Vibe Z Guides, News, & Discussion] donnyadhi:
Yes, I did, i've tried uploading via adb some zipped ROM, single qst file too, but always failed in signature verification..

I have install custom fw/rooted some android device before, but i've never stuck like this before.. :(
[Lenovo Vibe Z Guides, News, & Discussion] Crowds:
Then I don't really know since I won't have that phone.

I don't wanna lead you to take a bad choice and then you blame me but if I was in your place I follow this same guide with the difference that I would use your QST instead the one I've posted.

But that was me ;)
[Lenovo Vibe Z Guides, News, & Discussion] _mfm_:
I tried the "Install TWRP Easy & Clean - Simple but effective way to install TWRP with just one click" but it was easy one one-click insta-brick.

Now I try to fix the phone but if I go into QPST configuration and att the port it keeps rebooting the phone (but it doesn't reboot it if I don't use QPST). It does the same if I go into eMMC download (but at one time it may have been able to flash the bootloader, however it said status "error" after that and didn't want to download the image).

If the included drivers in "XP & win7_32位" would have actually been for 32-bit I would have tried on my other computer (but they're not)
[Lenovo Vibe Z Guides, News, & Discussion] dmarghe:

How's your battery at the moment you were trying that?!

If you needed up with nothing at all, probably was almost nothing.

Leave it for a couple of hours plugged to charger and see if you get something.

If not, check my thread regarding qpst tool and check post #6.

hi Crowds,

I bricked my phone ,The phone is being detected as an HID compatible device on windows,Whenever plugged into the charger or laptop's USB, it keeps vibrating for 13-15 seconds with the status LED blinking in red color.

can you help me.

hello again crowds , i removed all drivers and reboot more times but its the same issue, my dell laptop recognize k910 as HID compatible device.

I tried with all windows vertions 8.1 , 7 , xp all the same .and all usb cable lenghs 5 , 3 , 1 m.

withot battery windows not recognize k910 :confused:

with battery and once i plug usb cable the status LED in red color continuous for more than 5 minutes and dissaper.

there is any way to unbrick this phone.

how can i know battery is dead or not
[Lenovo Vibe Z Guides, News, & Discussion] Crowds:
[MENTION=5162673]mbaha[/MENTION]

Unfortunately there's no other way to unbrick this phone. At least as far as i'm aware of.

You''ll know when you're run out of battery. It just won't do nothing.

Now.

Try everything described on my guide but this time without installing LenovoDriver (the one witch make your phone be seen as HDI driver). Install just the COM port drivers.
[Lenovo Vibe Z Guides, News, & Discussion] mbaha:
thanks,

you mean virtual com port

I bricked my phone. I can not get it to download. What am I missing?

[IMG="k910 stuck"]https://c4.staticflickr.com/8/7474/15662508337_52d84c4bca_b.jpg[/IMG]

I think my problem starts with the QPST not fully recognizing the phone. The state is never "Enabled". It keeps trying and popping out a ton of messages to format the extra drives and then it eventually just shows no phone connected to the port.

Please someone help me. This is crazy how poorly supported this phone is. If I get my phone fixed, I promised I will rewrite a clearer tutorial for all to use. Thanks.
[Lenovo Vibe Z Guides, News, & Discussion] Crowds:
9006 is a "semi-brick" state.

To recover from that follow the guide on 5th post from 9th step.

Make sure blue LED is on phone when try the procedure, then its just straightforward

[Lenovo Vibe Z Guides, News, & Discussion] n1tro:
Sorry Crowds but your steps will NOT work for users in the same scenario as me. The scenario is that I partially bricked my phone using "1 click recovery" which turned out to "1 click sh|t" because I was on the original 4.2.2 firmware. Following your steps only results in the phone constantly vibrating and if you have the QPST program open, constant pop ups about formatting the partitions in the phone. To get even this far, there are lots of different steps I had to do because the instructions here are not clear at all.

First important step is to get the phone to show up under Device Manager. Pressing the volume buttons (any combinations) and plugging in usb cable did not work and only resulted in the phone eventually coming up as Unrecognized device under USB devices. I had to press and hold the power button until the phone vibrated and then it would show up under the ports settings.

Once the phone shows up I followed the following steps on post #841 pg. 85 of http://xdaforums.com/showthread.php?t=2597590&page=85

If the EMMC not work properly - you can use MiFlash ( I use it )

This the link :

http://bigota.d.miui.com/tools/MiPhone2.11.6.exe

This the steps:

Open the qpst configuration also to use the MiFlash

Note: If MiFlash ask for install drivers ( click on don't allow " don't change") Because the drivers not work properly with Vibe z

As you can see above, the data to be entered are:

1: The XML file flash with the corrected route (see Statute of corium)

2: The file in the same folder with the image of qualcomm mbn for the device: MPRG8974.mbn

((Remember put your X path: path \ MPRG8974.mbn))

3: the other image file mbn: 8974_msimage.mbn

4: The file to program the device rawprogram0.xml

5: Patch file: patch0.xml

Finally, press OK , refresh the list and select the device and then press flash. After the flash, if the phone doesn't turn on, charge it up for a bit since the battery has been drained from doing the above steps over and over again for hours. After a bit of time, press and hold the power button until it vibrates and the phone will boot up with the new 4.4.2 rom downloaded in the earlier steps.

Hope this helps anyone else in a similar situation as me.
[Lenovo Vibe Z Guides, News, & Discussion] Crowds:
1st I'm glad you make it

2nd my guide work perfectly on 9006 as on 9008. The difference will be from step 1 or 9.

3rd from the moment qpst saw your phone as 9006 that's because it sees drivers correctly and not as you described as "don't work"

4th MiFlash work? Great! That only proves that qpst will do the job as well.

Cheers
