Dear [MENTION=6608514]Electry[/MENTION] , is there any issue in using the following addon to your CM14.1 build?

I use your CM14.1 build in my daily k920 since it's so nice and my phone is like new even being 2yrs old..And I am scared of breaking something but I need It working. (I experienced so far only a very rare softreboot and a couple hard reboot: soft one started to appear from day I installed Chrome Canary, hard reboot one appear if I am in a zone with very weak and bouncing radio signals between 2-3-4G..All in all, nothing major ever! Great job so far!)

Please can you confirm compatibility?
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] Electry:
Yes, the kernel is maintained by me. There isn't an universal kernel for all devices because each device has its own drivers to work with its hardware. All Snapdragon 801 devices use 3.4.x (except for rare unofficial 3.10 ports), so its not really and indicator of 'version'. But we can still apply suitable patches from other devices into our sources, if it would help :)

The first one is just an app so there is really no harm trying, and it works fine except for the 'Your world, Solar System' wallpaper as stated in the thread, because of lack of libraries for ARM32.

The second one I wouldn't be so sure as it deletes a whole bunch of stock apps. If you want to try, just do a backup in twrp first, in case something goes wrong :)

So did anyone find any major issue in last LineageOS build?
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] pkb_always4u:
Both working fine, though live earth is not working as said from the developer and one minor bug in google pixel dialer is you cant cut the call (as it takes swipe down to cut the call and it is very close to the edge of the screen that doesnt register full swipe motion. I am using only pixel modification and unistalled the live wallpaper.

A major flaw in the CM 14.1 ROM is the battery drain!

With the stock S288 ROW ROM my phone was up without charging 2 to 3 days (with a record of 4 days).

With this ROM the phone would barely reach 22 to 24 hours between charges!

During the night, when everything is turned to off - Wifi, mobile data, bluetooth and GPS the phone loses more than 20% (!) of battery charge - just for stand-by, all for just 6 hours!

With any of my previous stock ROMs it would barely lose between 2% and 3% for the same time! The only time that I remember charging the phone daily was during the first 3 days when I bought it.

I am using the same apps in the same way as on the stock ROM.

This needs a fix!

My present battery is almost brand new original Lenovo K920 one, 6 months since replacement and being used quite adequately.

HI Friends,

New person here. I want the latest CyanogenMod on my K920. Can someone give me few short tutorial?

I used to flash Samsung Notes but now not in touch with new technology.

Sorry and thanks in advance.

regards
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] Electry:
Huh, I barely got one day out of stock rom, but I'll check it out. You can also check with BetterBatteryStats.

1. Backup your device/data/wharever.

2. Update to latest OTA firmware, it's S288 for International K920 if I'm not mistaken.

3. Unlock bootloader: https://xdaforums.com/k920/how-to/guide-unlock-bootloader-lenovo-vibe-z2-t3114307

4. Flash TWRP: https://xdaforums.com/k920/development/recovery-team-win-recovery-project-3-0-t3454739

5. Wipe system + data + cache + art cache in twrp. You don't have to wipe 'internal storage'.

6. Flash CM in twrp

7. Flash gapps from http://opengapps.org/ (ARM 7.1) in twrp

8. Reboot
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] cyprien T:
Electry you should put your tutorial to install a custom rom in the first page ...

It would push new k920 users to install your fun ROM!

Guys. Is there any way of blocking ads on YouTube without Xposed? I seriously want to upgrade to LineageOS but ads on YouTube are holding me back.

---------- Post added at 04:24 AM ---------- Previous post was at 04:15 AM ----------

Nevermind guys. All I have to do is turn off Google Ad services via Lucky patcher (pls dont ban for warez) for YouTube.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] lockhrt999:
I agree. When I tried to install the custom ROM the first time it took me a couple of days literally. Most of the info is separated into different threads and sometimes the instructions don't work the way they are supposed to. Drivers can't be found and I even managed to brick my k920.

How have you been blocking the ads in the CM? BTW have you fixed your Mobile's earpiece?
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] Saamyo:
Ooh... Nice for you to remind me about the earpiece issue. Is it still present? I can't let my phone not be a phone just to enjoy Nougat. And what do you mean by blocking ads in the CM?
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] lockhrt999:
I once opened my phone to unbrick it. I think you can easily change the earpiece by yourself.

About ads, I was asking how did you block the YouTube ads in CyanogenMod without xposed? If you blocked them at all.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] Saamyo:
To block the ads, I used Lucky Patcher (Non Xposed) and put the patch to turn off Google ad services for YouTube.

What is your choice for this screen?
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] nitinule:
You said my words.. At least a Word Doc file which can explain step by step tutorial and things you should do and you shouldn't.

Others can add inputs if new people do not understand any flashing related words.:good:

By the way I have Bricked my Lenovo K920 last night. Downloaded TWRP latest app from Google Play Store. My Phone was rooted. Now I downloaded some other Lenovo file on it and pressed some option. The Phone is dead.

Now Only Blue Led constant. Tried pressing Volume - plus Power. It Flashes only once with Lenovo Screen and again Blue stable light. :(
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] janforman:
If you see Lenovo logo in boot than your mobile is fine I think. Can you enter into TWRP? By pressing vol up / down together + power up device?.

You can try to flash TWRP by ADB and ROM can be flashed too.

TWRP https://xdaforums.com/k920/development/recovery-team-win-recovery-project-3-0-t3454739

fastboot flash recovery {twrpimagename}.img
fastboot reboot

ROM

adb sideload {romname}.zip

You must have correct drivers in your PC and mobile must be in recovery mode.

Volume Up + Power I think. For complete shutdown you must push power button for minute or long... This helps while phone is completely frozen.

Hello,

I just flashed it couple of hours ago, the Lineage build, it works pretty damn good, the only problem I am having so far is that, when I open battery saver and performance, for the first time it worked and now its giving me: Lineage OS Settings has stopped error.

Otherwise its working well.

Thanks

After our bazillion flashing I think we need to calibrate our batteries so that we could start seeing some standard expected behavior.

How can you calibrate the battery?
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] user700512:
Fine here after re-branding. :)

A nice lossless update, thanks Electry!

No need for any OTA app if all future releases are maintained this way! :D

Tested - wifi/mobile data on SIM1*/GPS/bluetooth (headset)/calls/SMS/browsing...

Both on CM/LA, Lenovo's SYNCit doesn't restore SMS from cloud, although is shows progress and reports success. It restored call register (at least on CM) though.

Bluetooth cannot be turned off through the status-bar tile, on both CM/LA need to tap "more settings" to turn it off. Turning on works fine.

Looks like battery use is a bit better than on CM during the day at normal use. I am at 45% now 14 h after full charge, while with the last CM I would have been below 30% by now**.

*slavislavi, AFAIK this device has no LTE on SIM2, only 2G. Are you sure you're not using your SIM1's LTE?

**Crazy_hatteR, did you have this on the last CM? It will be the 1-st night to test if mine still drains >20% for 6 hours just for standby - I will drop a note on this tomorrow...
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] slavislavi:
I know about factory limitations, and 2nd antenna could be not designed to LTE but it works. On 1st SIM mobile data limit was reached so switched to 2nd. Surprise download speeds are about 25-35Mbps
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] lockhrt999:
I'm sure it only works if you have stock Lenovo messanger app.

It's not a hardware limitation. Second SIM can be enabled for 3G and 4g .

---------- Post added at 10:31 AM ---------- Previous post was at 10:15 AM ----------

There are a few ways, Google can explain it better. I haven't done it myself yet but my mobile needs the calibration now. My mobile drops battery from 30% to 3% very rapidly but for last 2 percentage I get half an hour screen on time.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] Crazy_hatteR:
In last CM 20161225 no drain. The problem start with first Lineage 20170104. 3min in display cost 3% battery. Im go back in CM.

Today my device went into a deep sleep once. Battery after wiping cache behaves better than yesterday but not better CM.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] user700512:
Thanks! For me LA has had a battery performance just as bad as CM during the night - 20% down for 6 hours for standby AND with battery saver turned ON.

I have noticed that in "Use since last full charge" it was always CM/LA system that was earing up times more than anything else in the list.

Another thing I see in "Battery optimization" - Not optimized: Download Manager, Google Play services - these cannot be optimized.

I confirm! I have the same crash in LA. There was no crash in CM though.

I can no longer go to this screen:

Thanks. I thought messengers were using the same SMS storage. Why not, for God's sake… :(

I'm not that much into modems and just thought it's as straight as Lenovo say. I could not imagine a 2G modem perform as 4G. Is there any reliable source to point me to read about it? Thanks!:confused:

But, what I've been told is that LiPOs have no need to be calibrated ever, only cycles count. Furthermore, it is the battery controller that reports values to the outlaying logic. I'm not that deep into batteries either… :confused:
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] user700512:
I've got a silent self power-off. Battery level was 78%. After powering on, the default launcher setting was not remembered - I had to set it again.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] elry567:
Works fine on CM
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] lockhrt999:
When I said calibrating the batteries I really didn't mean changing anything about battery controller chips which is impossible. When we say battery is out of calibration, it means battery has 50%charge but the mobile is reporting only 30%. It's a software bug. My Mobile's battery went out of calibration when I migrated from cm13 to cm14.

[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] user700512:
I had to wipe Dalvik/Art, data & cache, then flash LA again in order to fix the "Battery saver and performance" crash.

So, one still needs to wipe before re-branding CM to LA.

Edit:

Starting all over again from scratch, I'm pissed! :(

Apart from the annoyance of:

- Developer options not enabled;

- Root not enabled;

- USB debug not enabled;

- Unknown sources not enabled;

+ There is NO cell data AGAIN as in CM. It is an outstanding chaos in mobile networking in these 2 ROMs. "Cellular data" switch cannot be made to stay ON by no means. Turned ON then <Done>, then check - it is OFF! @#$%@! Also, there is a blank "Cellular data usage" screen for quite a while. Also, there is a random mixture of Operator 1/Operator 2 label displayed below the status bar tile icon, although cellular data is enabled ONLY for Operator 1.

I'm going back to my "hybrid" CM-non-wiped-LA backup... :( ...for now.

BTW, there is something I don't remember seeing before in "Settings"/"Accounts"/"Add an account" - it shows a list of:"Default Eighteenth"/"Default Eighth"/"Defult Elevnth"/"Default Fifth"/... (that way alphabetically) ..."Default Twelfth"/"Default Twentith" above the list of the "real" account providers.

I'm still on CM from 14.01.2017 but last days I'm facing huge battery draining and phone is most of time hot. I'm on 50% now after ~3 hours. Could somebody post again link to download battery app from xda? I forgot the exact name of this app. I would like to check if it's the hw issue of battery. Phone is almost 2 years old. I tried wipe dalwik and cache but it seems to be ineffective.

yep, that's right.

Most likely caused by FB/Messenger app, as many people (also with different devices) are reporting the same issue. According to FB's VP they have already fixed it.

http://www.androidauthority.com/facebook-messenger-battery-drain-issue-742402/

Yesterday after 2hrs screen-on time I had only 12% left, today it looks much better.

If it still drains, reinstall FB/Messenger.

None of you have ever had problems with the cellular data management on these 2 ROMs?

How do you set your cellular data on/off to the desired SIM operator?

How come that I set cellular data enabled only for my primary SIM operator, but the damn stupid status bar cellular data tile icon shows my secondary SIM operator's name and then its statistics, and turns the cellular data on/off for it, instead of my primary SIM operator?

(For a better understanding of the screenshots, "Mtel" is my primary SIM operator (SIM1), "BG GLOBUL|Telenor BG" is the secondary(SIM2)).

How do I hard-link the damn stupid status bar cellular data tile icon to my desired SIM operator, for God's sake?

Guys, MX player on my phone can play HEVC (h265) files in hardware mode. How's that happening? Have we added hardware acceleration to HEVC on our ROMS? I know it's a hardware function and our 801 does not support that so how's that happening?

Edit: I searched on the net and found h265 video playback is supported at the hardware level on 801. Maybe it wasn't working on OEM ROM due to some limitation but now in our ROMs it's working fine. Yaaaeee. Another reason this mobile is good.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] Electry:
Yep, hardware based HEVC/H265 decoding is supported on S801, but only up to 1080p. (S800 doesn't support it at all and the S805 supports resolutions up to 4k)

Yesterday Lineage has disabled SU (root) by default.

Should I keep it as it is now, or would you rather I made a build with no root? (maybe for apps that don't work on rooted devices, e.g. Pokemon GO), and then those who want root would have to flash SU addon separately.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] Kurbatos:
I think if there are other positive changes, it can be done. And so, if the judge, that on January 4, the assembly is almost perfect. Who will start the discussion on pages 10 root. I foresee this)))

[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] lockhrt999:
I don't have any preference in this. I do use root sometimes and do not use a single app which doesn't like root. That said I wouldn't mind flashing SU if non SU ROM brings any features to our ROM.

I think currently our ROM is at its most stable state. I wouldn't want to trade that stability. We may try to make this ROM more perfect by say adding remaining features like working power saving mode, ultra power saving mode, different ringtones for different SIM, 4k shooting at 30fps, somebody had problem with DLNA or Chromecast back then, there are a couple of small bugs. It's my personal opinion that if new updates coming from lineage team don't add anything to already existing feature list (apart from changing the version numbers in about phone) it's may not be worth the hassle to update the ROM with each new iteration. I don't know how much work goes into going thru the source code, getting the right sources and compiling but if I have to guess, the work must be quite some. If my lazy bum was developing this I would have tried to add above mentioned functionality however much I could and called it a day. :D
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] janforman:
I am using root access sometimes, but no problem if it's not included in the build.

But what would make me happy is "default sharpness 0" in the camera settings, or less than 12 (which is default value).

DJI GO and many other applications use the default value and it is too strong even in 4K. It can't be changed because there is no custom settings in many apps so default is used.

Everyone in editing tool can raise sharpness itself, but undoing this if picture is oversharpened in source can't be done.

I believe this is set somewhere in Qualcomm camera settings, but I cannot find where.

But it's little thing, not that important. Anyway everything is cool :laugh: no real problems.
