Even I am not able to understand.. I would suggest use BBS.. And check if the deep is working.. Check gsam home page and match held awake time against phone up time..held up time should be minimum or equal to sot time.. Then check app sucker view.. Times held awake..

All this info is more clearly visible in BBS..

Better still try clean flash once.. Wipe cache, sys, data, vendor and delete android folder in twrp before flashing ROM.

Thanks again for this rom, I was intrigued to flash it cuz I liked Nougat Viper very much.

Ok this is the first version needs more polishing, some small thing are not working that work on Carbon rom, when comparing these two Carbon is more smooth, but uses more battery... It has standby drain of 7% for one night (8h sleep) but this one is much better, and percentage goes down very slowly when u use phone.

This could be the best non treble rom.

Please don't go for Pie directly, please make few more Oreo stable versions, Pie is great and beautiful system but it uses much more power. I'm used to get 7-8h of sot from this device, and with Pie roms max I can get is 5h of sot (I'm a light user, don't play games). Ok Pie is more responsive, but for a big cost.

If u can get this battery life to Carbon rom that would be perfect.

Thanks for ur work and good luck with the exams.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] sanjay.2704:
I agree with u 100%... Rom is very smooth..no issues at all while using the rom.. just needs a bit more finishing touches with some more customization as was present in viper nougat and then it would be complete..I would say best Oreo ever..

[MENTION=393300]yash[/MENTION] is great Dev and I am sure once his exams are done. We would have an update on this.. new year's gift I suppose:victory::fingers-crossed::fingers-crossed::highfive:..

One question dev? Did u block some wifi Wakelocks? I have delayed push notifications on wifi, disabled battery optimisation and locked in ram those apps...

Edit: now it works fine with my home router, I was on a trip so it must be something with friends router.

Rom is great, battery is awesome.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] yash_karande:
Yes. There will be a viper oreo build again 5.1(don't ask ETA tho). I've messaged the main devs for all the additional features y'all are asking. I hope they implement it.

If I'm right you're saying that carbon ain't giving good battery life as viper. For next build I'll give link for boot.img or kernel zip with a little bit of UC. It won't affect the performance but surely increase screen on time.

List any other things y'all want. I'll try to bring it for you.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] STARK0711:
Ur one of the good devs we ever have ...

Thanks for ur efforts buddy :svetius:
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] vuckovic_stefan:
Thank u mate!

For me Carbon is super rom, it more snappy and better performance. But standby battery drain is a little bit higher than on Viper, and generally battery is weaker. We can lower freq with KA, i think i did it but performance was decreased, scrolling in FB, Insta etc very a little bit choppy. Anyway its hard to achieve both goals, super performance and super battery :).

Thank you for everything. I'll donate as soon as im passing bank so i can put euros on account. I looked now u didnt post PayPal link, how can we contribute?

Can please some tell me where I can "Select to Speak" feature

Is it safe to increase the sound in Karnal Auditor to +20 because ViperOs 5.1 has really very low voice.

Phone calls are perfect even in crowd, but the speaker sound is very less. Have flashed the BFR kernel to get good battery backup but the battery is same that was on Jaguar may8 build or may be less. But it is more responsive and don't have those bugs I faced on jag. Performance wise both are super.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Priyanshu02:
Can you please give the link of original keral that came with this rom, it was Heliox or something, I don't remember as I flashed BFR after checking the stability of rom.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] sanjay.2704:
If u have the ROM zip with u just extract boot.img and flash that .. that's the kernel file
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Priyanshu02:
I don't know that it is only me or other are facing it too, when I play the music the sound fluctuates and seems to get lowered and higher at different phases of song. It is happening in every song.

It's not happening in earphone but the sound is very low also in the earphone as compared to Jaguar.

Please don't take me wrong. I'm not saying this rom is bad. In aspect of response and little in performance ,this rom is better. But it really require work on sound.

It may be because I flashed the BFR in greed of getting more battery life, but now I understood it's all my usage on which depends the battery backup. Will update my words after flashing the original Heliox keral which came with this rom.

---------- Post added at 04:02 PM ---------- Previous post was at 03:54 PM ----------

Can you please tell me how can I flash it. I extracted the boot.img from rom file but in twrp it was not showing in the folder as it was not a zip file.

Do I have to make it a zip file or can change its extension from boot.img to boot.zip.

Please reply quickly as my sound on this rom is very much low .

Update :- I flashed the original kernel of this rom and now I am feeling that battery backup is just awesome.

Thank for answer in advance.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] yash_karande:
The speaker issue is from the h/w itself. Z2 has weak speakers. The distortion happens when you use sound gain. And afaik bfr has sound gain. Either use kernel adiutor and lower the sound gain. Or lower the volume while using speaker.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Priyanshu02:
I have flashed the original Heliox kernel now and everything is working fine. Yes this phone has low sound but with BFR I found myself losing more sound instead of gaining. Maybe the BFR kernel is not good for this rom. As in original kernel I found my sound slightly higher with more clearance.

While in BFR kernel my songs voice was going up down on speaker .

Thank you for this rom

[OnePlus 6T  Questions & Answers] Somehowko:
Hello guys! Ever since I got my new oneplus 6T, I was struggling to get volte on the phone (and still failed.)

Now, I gave up. Really I cannot find an answer for the problem (as Korean carriers including KT requires specific way to mass around twrp)

and I am worried if TWRP files that I modified, deleted or changed will affect the phone in anyway.

Would there be anyway to factory-reset TWRP files?

Before you say anything I am really sorry for asking this question. I don't really know that much about TWRP and how the whole things is supposed to work,

I just wanted to activate VoLTE not to have a horrible call quality.

If this can be fixed with just a factory reset, I already tried and few files that I added are still remaining in TWRP folder, so I guess this is not the solution.

And for those who think I am stupid for not making back-up files before doing anything, yes, I am for deleting the back up by an accident...

I don't know if anyone out there can help me with this or this is something that will cost my three old phone, but I do appreciate any efforts put into this.

Thanks.

And what exactly is the problem you are trying to fix? Did you do an EFS backup before messing with the Modem?
[OnePlus 6T  Questions & Answers] Blueblob:
He can't. No TWRP for 6t (only a workaround with TWRP from 6)

Btw : VoLTE profile files are not in efs partition but in some firmware files. So flashing stock should restore factory profiles.
