Is your mobile "seen" by computer? If yes it should not be a problem to recoverit even if you have locked bootloader.

1. Download software (twrp_2.7.1.2_recovery_K910SS_4.2 or twrp_2.7.1.2_recovery_K910SS_4.4) from: http://4pda.ru/forum/index.php?showtopic=546814&st=2820; (second spoiler from top website);

2. Start 42_flash_twrp_recovery_K910SS_dd.bat for 4.2.2 or 44_flash_twrp_recovery_K910SS_dd.bat for 4.4.2;

3. Switch of the mobile, press simultaeusly Volume Up and Volume Down and connect mobile to computer;

4. If your mobile is "seen" by computer software do the rest.

[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] Sean09:
Thanks for the suggestion. I can see it in device manager as MTP device when at the lenovo screen (and a generic "H" as well if I recall). In download mode I get the QPST 9008 etc that you're supposed to when the drivers are installed. I tried what you suggested and it doesn't work no matter where in the process I launch the bat file.

That being said, even if I did get TWRP recovery how would that help? I cannot get to the main recovery to restore a QSB (holding vol - and power), and I assume it'd error again even if I installed Vibe 2.0 over OTG?

Is there some sort of recovery master flasher or something? Given I get 4-5 format drive messages when plugging the phone in I suspect the partitions are either damaged or wiped clean. It is times like this that I wish Odin or something existed.

From what I understand the locked bootloader is why the volume down and power wont work? Any other tutorials or ideas?

---------- Post added at 08:55 AM ---------- Previous post was at 08:28 AM ----------

Further to my last post I have also tried the QPST option outlined at HTCMania.

I have pasted the translation and photos below to assist others as it didn't translate or format proper for me.

My confusion and issue seems to be that on both PC's, despite the drivers being properly installed, Step 1 never says enabled - it always has a green progress bar. My phone also shows up as status not ready (as in photo when not in DL mode) and locked if I recall correctly. I will have to try another PC. It also seems as it times out waiting for device on step 7, then reboots to the lenovo logo.

Any ideas are appreciated, and I hope the above somewhat clearer process helps others.

Did you ever get a solution for this? Pretty much on the same boat, same situation, same results.

I have now also tried MiFlash when my phone is in 9006 mode and get the error "Incorrect function. (0x80070001: WriteFile Position 0x00000004000000, size 1048576)" at 5%.

an expert saved mine with win8 x64 pc,

some guys saved in winXP x32

all they used miflash,

in htcmania in recovery rom, the mbn file is old-wrong.

here is the correct rom to use with miflash. ( only mbn file is different actually)

https://yadi.sk/d/OXNfIeJgWyMt2

all you need is windows version and the drivers up to that windows.
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] Sean09:
Thanks very much, I will give this a try when I get home. I found 3 different MBN files floating around and none worked. I assume this one is for the dual sim version of the phone? I hope that works. Seems to be the issue is that it will not mount my phone as writable.

The first good news is that at this stage, you don't need bootloader mode but recovery (there is a slight difference). The second good news is that freejess just posted a link which explains how to use the zip file I posted. Be aware that as far as I know, you first need to execute all the upgrades before being able to use the one from the link.

This ROM is the official one from www.viberom.com but it's the development version (unstable).

Multilanguage is indeed a false information as is the presence of a SD slot and the LTE functionality (although this last one could be activated at some point but this is dependant of Lenovo's will)
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] freejess:
You are saying it is possible that active lenovo LTE by updating rom dual sim model?

[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] csu333:
What I say is that the Snapdragon 8974 which is supposed to equip the K910 supports the LTE. It should then be activable like some people succeed with the Nexus 4 a while back. But between the theory and the reality, there is a giant step...

can anyone share me the ADB driver, as the phone i brought don't have any CD with it.. thanks alot~~
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] csu333:
This means you have the factory version ;)

The CD is emulated. Just plug your phone in an USB port and you'll see the CD with ADB driver appear
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] invisiblelim:
ok.. found the CD and driver.. thanks alot~~

any restriction from getting the factory version? so far i notice i can't add chinese as input keyboard language.

besides, i had downloaded the firmware you mentioned stuck at K901_SS_S_2_040_0039_131101, is an zipped file, but i checked tutorial it need a QSB file, i just rename it will do?
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] csu333:
The QSB file allows you to make a factory reset of your phone. It won't help you in the upgrade process.

To apply the upgrade from the ZIP I uploaded, use the method described in the link provided by freejess. Note that wiping is not needed in your case.

You could alternatively try to download the latest firmware from www.viberom.com but I'm not sure if this is cumulative (worst case, it fails and you downloaded almost a Gb for nothing, best case, it works and you made the upgrade process only once).
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] freejess:
Hi! Can you confirm that this method works with Windows 8.1? Thank you

I bought Vibe Z in Thailand with android 4.3

Can I use this method to root the device???
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] csu333:
I'm pretty surprised that you already have a 4.3.

As I said to other for the single SIM version, the best way is to try. In the worst case, you won't reach the recovery. No chance of bricking your phone up to there ;)

Hi, have you resolved your problem ?
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] csu333:
I'll always be amazed to see how supposedly identical devices (at least, they have the same reference) can behave so differently. I have the same ROM version but I can still boot the custom recovery without any issue !

Have you tried:

fastboot oem unlock

That's the only thing I can think of right now
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] csu333:
I guess that you already enabled all the sync categories you could need in System Settings > Google > your_account@gmail.com so I'll take it to the next step.

You'll probably "just" need to push GoogleContactsSyncAdapter.apk to your device. To do that:

Download the Gapps zip from the first page

Extract the file I just mentionned

Try "adb push GoogleContactsSyncAdapter.apk /system/app/GoogleContactsSyncAdapter.apk"

It doesn't work because even rooted the system file is not writable

Download custom recovery from first page

fastboot boot recovery-custom.img (I'm not sure of the precise name but all of this is documented on the first page)

adb push GoogleContactsSyncAdapter.apk /system/app/GoogleContactsSyncAdapter.apk

You should have your contacts able to synchronize
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] Sean09:
Unfortunately it is still not writable even with your files. Stuck in 9006 mode and even miflash wont write to it.
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] Sean09:
Finally fixed the %$^%^& bricked phone. Used Windows XP 32bit. I was having the same issues I had been having all week. Ended up getting it going by fluke. I was at the part where you have to hit download really quick. I was trying to power off the phone while holding both volume directions when it kicked me into 9008 and held for some time. Hit download, then flicked on program, and it went all the way. Then I held power and volume down, restored from a OTG usdb key with sdfuse directory!!!

Im new owner of Vibe Z from Tuesday. Im currently runnin on vibeui 2.0 1431, but system gives me updete on 1433. Do you know about any issues on that version?
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] Sean09:
Now that I have VibeUI 2.0 running I cannot seem to install Google Plus (after using GMS Tool). Is there a better way to get google services running since I cannot flash gapps? Also, anyone successfully remove the security app? Uninstalling leads to a watermark, and freezing gets undone every reboot.
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] Sean09:
Fixed both issues. com.google.android.maps.xml was missing from the permissions folder, and I replaced the security apk with an older version that doesn't work from another thread.
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] gimmeluck2:
.

1) i have used the ROM from needrom.com

VIBEUI_V2.0_1431_K910_baralajbi_V4

it was almost perfect.

all my private files deleted inside the phone by factory reset commands in cwm

which i liked.

2) Just because its ST version , i tried this new one:

VIBEUI_V2.0_1433_4_ST_K910_baralajbi_V5

but it looked some strange.

my files havent beeen deleted by factory wiping etc, even it was the same CWM and the same the adb loader, everything the same!

why? how it can react different?

Hello,

I'm currently runnin' on VIBEUI_V2.0_1431_DEV_K910_baralajbi. That ROM was pre-installed from seller. He was very kind that he made ROOT but he forget to install custom Recovery, what a dumbass... but it doesn't matter. System offers me upgrade to V2.0_1433 but if i press apply button, phone reboots into black screen and notification LED lights blue and nothing happen. Same situation is when I try to make Factory reset or if i tried rebbot into recovery (from quick boot aplication).

Do sb had same issue? What is the easiest way to get CWM into my phone (i'm able to boot into default recovery and there is an option to install update.zip, i think).

EDIT: I think that pre-installed (or original) recovery is not compatible with that ROM, so that processes can't be done.

Here is photo of current recovery:
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] newbie_vlc:
You are on 4.4.2 Android version, then the bootloader are locked and In this situation we can't load CWM, there are post on russian forum with a tool that unlock bootloader, but I don't remember read nothing on english or spanish that sure that.

On 4.4.2 Android version actually only works TRWP, there are some tools that executes from an exe with the smartphone powered on and with su feature install the recovery. Read the post and you will find it.

Good luck

Yep, I've allready noticed that. But If I tried to flash TWRP from that tool I was stug in bootloop, fortunetly WIPE from that service menu helped. You know, Lenovo has same conference in Prague today and they going to enter officialy to our market (in Czech republic), so I will wait what kind of support they offer and if VIBE series will not be supported, I will flash it by my own.

But thanx anyway for ur help.

Yes, we need to download to Android 4.3 first, then flash TWRP recovery and then flash the Android 4.4.2 firmware and then SuperSU

BTW, VIBEUI_V2_1427_baralajbi is not really rooted, Root Checker return "Your device is not properly rooted"

Hi! I'm planning to buy this phone, but I have some questions:

- Well, first of all, would you recommend it?

- Battery performance?

- Custom roms. It seems there is very few options to choose. Am I wrong? Do you know if anyone is developing a CyanogenMod, MIUI or some other rom that is not VibeUI? This is what worries me the most. But I really like this phone and I think I will end up buying it.

Thanks in advance.

Better wait for K920 Pro.
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] Dapalm:
Althought the K920 looks amazing, it's very big and probably out of my budget.

Edit: my budget is arround 250€, the other option I've seen is the ZTE Grand S2. It has better specs, but the build quality is worse, and the design is too similar to my current phone (ZTE v987). I can get the Lenovo for 220€.

Another question, my current phone uses a special jack (omtp or something like that, chinese standard) and searching compatible earphones it's a pain in the ass, would I have the same problem with this one?
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] gekkorist:
no, soundjack is normal 3.5mm

... 3 days ago, i recommend the phone, but now, after brick... not.

the support is a pain. Alltime use the google translator.. only russian/china/spain sites with good solution and support.

Battery performance is one Working day without problems.

is in your choice.. i wait now on the zenfone 5/6

Now the post itself :dios:

First of all sorry for the English use instead if Spanish but i can describe my issue in a better way than use the ridiculous google translator :D

Ok.

1. i got a bricked Lenovo K910 without acess to nothing except logo on boot. no download mode, no bootloader unlocked...nothing.

2. i've tried for the last couple of days everything that i could find on the internet, including this threat, this along with some tips from here. Nothing worked :(

Now my difficulty using this threat or the other mentioned from HTCmania:

1. I've installed all the files mentioned in 1st post

2. Try to boot k910 with the key combination [VOL- plus Cable Insert]

the only thing i was able to get is (see pic)

3. i tried to install Qualcomm drivers manualy but no matter what i just got this (see pic)

and i get the same result for 9008, 9006 and the other available 900D
