Waiting for some reviews
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] Saiyajin:
So has Lenovo already released a final KitKat Rom for the K910 (dualsim)? Want to upgrade, because my 1403 build is a bit buggy.
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] tedulus:
Yes, u can download it on vibeui.com
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] Saiyajin:
So the 1420 build is an official, stable rom? Can I root the ROM and install GApps?

If so, can somone give me an installation guide on how to upgrade to the 1420 Build? I'm coming from 1403 rooted with gapps.
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] tedulus:
I am waiting myself for some review about 1420
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] zbisz41:
Colleague installed today a new soft 1420.

ROM 1420 GAAPS and ROOT enters through ADB sideload. .As in the version of the 1419.
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] tedulus:
So, the bootloader its unlocked ? Or it works by flashing 1226 then 1420 then su then gapps ?
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] PanNet:
It is rather not possible in that way at the moment. In 1420 version bootloader is locked so you can use adb sideload but SU and GAPPS can not be installed.

Regards
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] zbisz41:
dear friend In 1419 version also bootloader is locked .

To install GAAPS and Su , we do this by returning in 4.2.2.

in CWM after installing the rom 4.4.2, enter the Sideload and ADB sideload .

4.4.2 Installation of gaaps and su:

1) first install 4.2.2 ROM to your phone

- extract the files

- copy to SD/sdfuse folder the K910_SS_S_2_040_0109_131226.qsb file

- switch off the phone

- push together the power and volume down button

- if the phone switched on, choose the 4. SD Update and follow the instruction

- reboot

- Now go to install the 4.4.2

Install 4.4.2 ROM :

- Download all files

- boot into bootloader (adb reboot-bootloader)

- boot into CWM recovery (fastboot boot cwm_recovery_custom.img)

- flash the rom with recovery (adb sideload filename, or from SD)

- If you want to root, then flash the UPDATE-SuperSU-v1.94.zip

- Reboot

Hi there,

Show as the pictures! It DOES NOT work like in 1416 or 1419. You should have read Russian Forum more accurate. Personally I did it a few times and without success. I never ever leave information before has been checked.

Regards
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] zbisz41:
I do not see the Russian forum no instruction,how to write it in 1420 Su.I wrote what he did mate from another forum.

I'm waiting for confirmation.

Russians confirm ROOT as in 1419-thank them very much.

Bulgarians apparently also.

Polish user also.
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] _mfm_:
Surprisingly, it does work perfectly for me:

Exact commands used:

Confirmed, working for me too
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] madkhaz:
just need to do the command as above? no need to reboot into cwm?
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] tedulus:
reboot into cwm, install zip, install zip sideload
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] madkhaz:
flash the rom 1420 zip, then gapps and supersu in sideload?
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] tedulus:
Sideload from cwm
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] Saiyajin:
I'm coming directly from 4.2.2. Unfortunately it said "bad" when i tried to install superSU or GAPPS. So i just rebooted the device and wanted to restart into cwm, but now adb tells me Failed (remote: "locked"). I assume i have to reinstall 4.2.2 with the QSB.

But where can i find the QSB for download?

K910_SS_S_2_040_0109_131226.qsb
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] tedulus:
search google for K910_SS_S_2_040_0109_131226.qsb u will find it
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] Saiyajin:
Yeah thanks for the advice - after 40 min searching i found a working download.

Anyway: i reverted to 4.2.2 and repeated the steps to update to 1420 - but again, i wasn't able to sideload the files, because my laptop and pc don't recognize the phone, as soon as it's in CWM. Tried reinstalling the Drivers several times but no luck...

I was again able to install the 1420 Zip, but got again errors when trying to install gapps and superSU.

Do i need some special drivers for adb sideload?
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] madkhaz:
can you tell the proper step to do this update 1420? i'm coming from 1407
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] tedulus:
It must be a driver problem...
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] madkhaz:
i got stuck at waiting for device, after enter the command fastboot boot recovery.img.

why is this happening? @.@
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] tedulus:
With phone closed keep vol + and vol- and insert the data cable, it should be in adb mode
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] Saiyajin:
Well, that's obvious. That's why I'm asking if I need additional drivers, or if the Lenovo USB Driver is enough. I've removed and reinstalled the Lenovo drivers several times already.
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] _mfm_:
1420 works fine for me so far, but I had the same battery calibration issue as someone else had with 1419 earlier (it stayed on 40% for a long time even after an hour of 3D gaming, no it's not THAT efficient... Before upgrading I had 80% or 90% too, so 40% was obviously wrong). Discharged it and it charging now, so it should be OK after that.

By the way, in the 1416 DEV you could use "nightvision goggles" from power manager so be able to set the display brigtness very low for night usage, did anyone find it in 1420?

---------- Post added at 09:27 AM ---------- Previous post was at 09:25 AM ----------

You probably don't need additional drivers, but you need to remove the current drivers from Device Manager and install another driver. I had to do that to get ADB sideload working from CWM.
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] tedulus:
I cannot find anything better than 1416, same problems for me, location innacurate, sms font size keeps changing on its own, it does not recognize contacts whos nimber comes with country code, antutu score is even lower than 1416, and some other things
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] _mfm_:
Did you have working network location on 1415? I'm sure they use Baidu network location and not the one from google... Doesn't work so good for me now either.
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] tedulus:
I had only 1416 and it had problems from the start. Maybe someone will modify the rom, or maybe lenovo will make a row rom
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] Saiyajin:
I did it - i just had to force-install the Lenovo drivers via the "have disk" option in the driver installation GUI.
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] tedulus:
Very well, and what is your experience with 1420 ?
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] _mfm_:
If I "kickstart" the location access by enabling all location options, enabling "battery heavy location" and get AGPS-data by GPS Status & Toolbox then network location seems to work, I get weather location immediately without it starting GPS or anything (and it updates too).

It still seems that it's using less battery and less RAM than 1416, so that's good.

Lenovo has no big reason to fix the phone number match, the network location (which seems to work now for me though) or the Chinese city in the weather app / smart cover display since it all works for their customers on China Unicom in China. You can have weather for foreign cities in the weather app without using VibeXpert though, but you have to enter the name in Chinese.

You can have working SMS function by changing to Hangouts.
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] csu333:
Same here. By pushing a bit the location options, I've been able to get it as before.

As for sms, I can now use Go SMS Pro as I did before since under Kit Kat, I can finally send messages from the second SIM. I still have issues with the notifications though.

My bootloader is locked now so I'll need to unlock it before trying to update CWM (my firsts attempts didn't work)

[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] madkhaz:
so, 1420 is quite stable kitkat version for k910?

by the way, i'm from 1407. do i need to update to ss2 rom before upgrading to 1420?

i'm always got stuck at waiting for device after enter the fastboot command.

i have the latest driver i think

thanks in advanced :D
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] sektopod:
got a HUGE problem guys

Bought this terminal from Etotalk, arrived yesterday. Today I used it while in car, well everytime Im in car and the road is not perfect ( holes and stuffs like that ) , my phone sound gets horrible , i can barely hear other voice, and Ive to hang up to fix the problem.

Any help ? I work so this is a common problem =(

thanks
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] _mfm_:
You don't need SS2 ROM, I updated from 1415. Waiting for device means you have the wrong drivers.

Overall 1420 is the best version so far for me (even if I may miss some small details from other versions). This in everyday-performance and usage, I'm not considering synthetic benchmarks.
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] Saiyajin:
So, i've been using it for the past days and I'm happy so far. Battery Life is pretty good - I'm on 12 % now, after 60 hours (=2,5 days). It feels more responsive and the menus are partially reorganized (but in my opinion better). I didn't have the chance to test GPS or to run benchmarks, but at least I don't see an obvious difference. I think RAM usage is less. Other than that, it feels the same way, it did with Android 4.2.2.

Edit: Oh I forgot - i might already have discoverd a bug. After using WiFi for a while and going from place to place whil WiFi is switched on, it didn't show and/or connect to access points today. I disabled and re-enabled WiFi serveral times, but it wouldn't see any APs. So i had to restart it. Don't know if it's a "one-time-anomaly" but maybe someone will experience it as well.
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] DalSegno:
Hi guys,

After I get into bootloader mode, "fastboot boot recovery.img" returns a "FAILED: (remote: Locked)" when trying to boot CWM. Any ideas? Just OTA'd up to 1420.

If that doesn't work, any other way I can get into CWM?
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] tedulus:
U have to downgrade to 1226 and then upgrade again, read the post it is explained for at least 10 times
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] DalSegno:
I've downgraded already, installed GAPPS and SuperSU now and it's all working. How do I now upgrade to KitKat? Won't I just end up right back where I was, with 1420 installed but not be able to boot into CWM?
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] _mfm_:
There is an instruction on the Chinese K910 forum but I didn't try it myself: http://bbs.lenovo.com/vibez/t372914/

1421 DEV was released two days ago, did anyone try it?
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] madkhaz:
how to know that we get the right driver?
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] DalSegno:
edit: maybe don't do this yet, after GAPPS is fully installed and working, you do a reboot then it bootloops after loading up.. seems to be a conflict between google launcher and the built-in one.

edit 2: ok well I went into CWM and formatted /cache and things seem to be working.. not sure if this bootloop will return.

Oh,

and then once you're all up to date... I recommend flashing the 1421 modified ROM from the Lenovo BBS here: http://bbs.lenovo.com/vibez/t377123/

As I understand it there's 4 variations, I chose the last one which appears to be the most slimmed down one. You flash it right over top of your rooted 1420 w/ CWM already installed. It says many times DO NOT wipe anything, simply flash over top, then follow up with SuperSU immediately, then you'll have to do GAPPS again. It has some weird resets when you first get going again so don't panic.

Noticeably faster since it doesn't have the security suite on it. I had to clear cache on google keyboard at least twice before it would work.
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] _mfm_:
You should flash the GAPPS without the google launcher.
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] PanNet:

I am now on 1421, the version made on the Lenovo BBS. There are some new custom ROMs out (CSROMV 1.7) on that BBS as well that look pretty good.

So right now I'm in the 1421 slim version, and I run it with Google Now launcher and AcDisplay, and it's running great. You'll have to go into MIUI Express and disable its lockscreen though.

I've also been using it at 320 DPI which looks pretty great:

[MENTION=1065032]DalSegno[/MENTION]

is the CSROMV 1.7 ROM multilanguage? And do I see correctly, that it has Google Apps working without that annoying Secure IT tool?
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] DalSegno:
I think all ROMs from Lenovo BBS will be chinese/English only, no other language that I can see. If you flash CSROM 1.7, you need to flash the other file in the same post that disables Secure IT and flash it after. You will still get it show up once, but then when you reboot it's gone.

What is the file that removes secureit ? It works ok without it ?
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] Rigardi:
It would be a pretty neat move if you could make the ROMs you download from Lenovo BBS available by uploading them at some filehoster. Would be way easier than requiring everyone who would be interested to register at the Lenovo BBS. So rather than having 10 people create 10 accounts for a forum they are not going to use for anything else but getting those ROMs, it would be a far easier solution to make use of the one account that already exists :)

how to backup the current rom that i use before upgrading to 1420 or 1421? i use 1407 right now
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] Rigardi:
yes, they do that, because actual Chinese user joining the BBS would make sense to them. This is why they ask that. there is no harm in sharing the ROM with other users who would not participate in the Lenovo forums anyway. Therefore Id like to ask you again, to upload the CSROM somewhere and provide us with the link (or provide us with the link to the actual download source and the password).
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] DalSegno:
No. The developers have explicitly asked not to share it on other forums. Just because it's inconvenient to you doesn't make it right to ignore their wishes. Development will likely ONLY progress on the Chinese forums since this phone is Chinese. So just install Chrome, turn on auto-translate, join the forum, and get all the ROMs you want.

I have flashed it via Flashify and instead of those multicolour strips now it boots into android, no recovery...
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] DalSegno:
Typically you would flash a recovery with the following commands:

adb reboot bootloader

fastboot flash recovery recovery.img

of course replacing "recovery.img" with your recovery file naeme.

Hi,

I can't see any way to flash TRWP Recovery v2.7.0.0 if I am at 4.4 ROM unless somebody finds the way to unlock the bootloader. I tried to flash from 4.2.2 and 4.4.2 rom. But I can't see it in action.

Is there any possible button combination to show that recovery as in some 4.4 ROM's?

Inside the update script we can see:

package_extract_file("twrp-recovery-20140528.img", "/dev/block/platform/msm_sdcc.1/by-name/recovery");

I am not sure, but it seems it doesn't change anything. I also wrote on the chinese forum for any directions on how to use it.
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] DalSegno:
In the 1421 DEV package, the one with the 4.2 recovery and 4.4 recovery, you could try replacing the included recovery.img with the TWRP one then run the batch file.. no idea if that would work. I tried it with an english CWM and it did NOT work. But then I put the chinese CWM back in ran the batch file again and it restored it just fine.

---------- Post added at 02:40 AM ---------- Previous post was at 02:06 AM ----------

No luck at this point, I tried to modify 1423 CSROM but I am facing two issues:

- GAPPS addition: I can't install google apps. Maybe there are major changes on the framework that make impossible to work.

- TWRP: after adding it to CSROM.zip it installs, but original recovery appears when I try to boot from recovery. Tried chinese and english version.

I am also trying to develop a MIUI version for Lenovo K910 based on 4.2.2 ROM but after solving every problem to install it, we see the MIUI logo but the device get stuck on it. We see that PC recognises it as a non-ADB device in that point, but I am not able to debug what is going wrong ... hope somebody can show me any way to debug it. It could be useful to find out which drivers are not ok.

How would one be able to get the file for you? A quick search doesn't turn anything up.

---------- Post added at 09:14 PM ---------- Previous post was at 09:11 PM ----------

CSROM already suppresses SecureIT (assuming that's what you mean by Safe Center), but it only does it after you boot up once, accept all the SuperSU requests and reboot (then it's gone forever). I think somewhere along the line the phone requires it to install anything. If you just freeze SecureIT with Titanium for example, you can't install anything from the Play Store. My recommendation is just to leave it in for now.
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] ertioct:
That's good, I am just trying to install gapps and unfortunatelly I haven't the chance to check if it is gone. I always revert back to 4.2.2 backup because I need my phone to work.

Anyone has tried GMS.apk ( e.g. http://www.androidfilehost.com/?fid=23329332407592296) to install GAPPS in CSROM?
[Lenovo Vibe Z ROMs, Kernels, Recoveries, & Other D] DalSegno:
I can't remember if I tried GAPPS on 4.2.2.. you'd have to use a Jelly Bean GAPPS right? I know that paranoid android GAPPS for kitkat works great on 4.4.2 (and CSROM).
