Thanks does this work with VOLTE in india since I faced issues with 1.70 baseband while 1.76 works fine.?
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] deeppaul589:
This is not a new baseband. This is the baseband from ZUI 2.5.

Screenshot after flashing.

View attachment 4473647

This baseband is already available at https://zukfans.eu/community/threads/zuk-z2-baseband-collection-versions.4565/
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] K001droid:
February's LineageOS 15.1 and April's LineageOS 15.1, the version that is 15.1 is same, but does that mean it is the SAME?

NO, There is a huge difference similarly, Zuk has stopped Changing their baseband versions even though they have updated it on ZUI 3.5 Oreo and now in the latest ZUI OTA of 3.5.337 they had included updated firmware.

Anyways, this Firmware was provided in the latest ZUI OTA UPDATE :)
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] Incrovantilist:
Hey man. Thanks for the zip. I'm in AEX Oreo and running 1.70 Chinese. I had a pretty bad f*ck up with updating to 1.70 (bootloader locked and all). Now, can i dirty flash this file without facing any such issues at all?
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] K001droid:
Yep, you can.

This zip won't lock ya bootloader
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] Incrovantilist:
And Data also left Untouched?

Pretty much what I'm asking is can i just flash this in twrp with no consequences and only updated baseband?
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] K001droid:
Yes
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] Andro Enthusiast:
The purpose of this thread itself is to let users know and update firmware and baseband to latest ZUI Oreo's in a simple TWRP way !
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] Incrovantilist:
Thanks a lot man [MENTION=7174278]kubersharma[/MENTION]

I just updated and no consequences like you said.

I can still see fluctuations in jio signal but it's lesser than before. I would say this is like 20% improvement over my previous baseband. I appreciate even 5% improvements so this is good for me. Thanks again.

Update:-

My gps broke recently (even before i flashed this) and flashing this has not changed that. Do you have any fix for that in mind? Any help is very much appreciated.

---------- Post added at 06:01 AM ---------- Previous post was at 05:58 AM ----------

I don't mind simplicity. Last time I updated my baseband through twrp, my bootloader locked and part of my data gone. I had to make sure I didn't get there again.

I don't use Jio and so I can't comment on it.

But as per [MENTION=7174278]kubersharma[/MENTION] , the zip doesn't break Volte. But its always better to take backup of EFS partition.

Baseband 1.76 was stable and so is Baseband 1.70. I don't see any big improvements with regards to signals as such. But I surely don't have any issues too ! I get the same stable connectivity in both Mobile Data and Wi-Fi like before.

This zip mainly updates the firmware to ZUI Oreo's which makes our device more compatible for Oreo ROMs ! This is definitely an improvement :cool:

[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] Andro Enthusiast:
The Baseband that you have linked (2.0) is a custom baseband made by [MENTION=2823824]davidevinavil[/MENTION]. I have not tried this. But I have seen users reporting it to be good in ROM threads !

The Baseband and Firmware mentioned in this thread is extracted from the latest ZUI Oreo for Zuk Z2 Plus by [MENTION=7174278]kubersharma[/MENTION].

I have flashed ZUI Firmware and Baseband zip and I have no issues with it. This zip mainly updates our firmware along with baseband.

Its upto you to decide which baseband to flash ! Read the OP and 2nd post before you flash !
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] frozenfirevr:
Ah... Didn't know that was custom. I'll try this one then. Thanks ^_^ I must say though, feels weird going to a smaller number to update :P
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] frozenfirevr:
Flashed but no noticeable change, network signal still keeps fluctuating a lot. But still, thanks for the new firmware.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] Andro Enthusiast:
Zuk did not change baseband numbers after ZUI Nougat for China. Hopefully they have made changes for good in ZUI Oreo without changing the number !

There are signal fluctuations in Baseband 1.70 like Indian ZUI Baseband 1.76. But I never had any connectivity issues in both 1.76 and the new 1.70. You won't have too, hopefully !
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] NaXal:
I am with PE (ROM) + AR (Kernel) running baseband 1.70 (from stock ZUI 3.5.xx). Compare to ZUI 2.5 (Indian stock ROM) with baseband 1.76, I am facing Jio reception issues. With present 1.70 (with custom rom / kernel), Jio is unable to stay on 2300 MHz and falls back to lower 1800 or even 850 (what is available in said location). Same place, with stock 2.5 ZUI running baseband 1.76 had no reception issue, stable 2300 MHz connection !!

Beside, with (custom rom / kernel) 1.70, my WiFi link seems to be limited to 72mbps (under 2.4GHz) !! Earlier with stock 2.5 ZUI running baseband 1.76, I had 150mbps link !!

Not sure if it is something to do with ROM+Kernel or baseband only.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] AstroBiswas:
Thank You So Much [MENTION=8786194]Andro Enthusiast[/MENTION] & [MENTION=7174278]kubersharma[/MENTION] Jio Signal Fluctuations are gone now. I'm forwarding This Thread To Threads of Other ROM So That Everybody Knows About This Wonderful Baseband:victory:
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] vuckovic_stefan:
Thank you man.

This baseband seems better. I had signal fluctuations and data connection drop sometimes completely and comes back after 5-10 seconds.

For now look good, better than 243 dev stock ZUI Oreo
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] NaXal:
I am running this baseband but didn't flash via TWRP rather moved to custom from ZUI 3.5 itself.

Jio network fluctuation is still there, but biggest problem is limitation of WiFi link speed. Tried two different ROM (PE and RR), but except stock ZUI, I see the WiFi is limited to 72 mbps !!

Stock ZUI (regardless of 2.5 or 3.5) had 150 mbps link without fuss.

Tested this is at-least 4 routers (2.4GHz) in 3 different places.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] vuckovic_stefan:
I definitely see improvement in signal strength and fluctuation on AEX 4.5 LATEST.

BTW what is your internet speed given by provider?

You have to set 40mhz N mode on wifi router to see that link speed

Or maybe on custom roms it is actually limited but doesn't make any sense
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] NaXal:
Network reception is really tricky to comment on. I myself understand this. It is depended on so many variables, plus I am not expert on this regard either. Only thing that I can do is observe via my network provided app or phone settings itself in few parameters.

I am using Indian network Reliance Jio. Now they have a tool available in playstore called "NetVelocity". It gives detailed information in real time for network reception parameters !! Jio has 3 frequency at my telecom circle. 2300Mhz/1800Mhz/850Mhz.

Now for testing, usually that is either my work place or home (so keeping the place and time same), I tried following. Stock ZUI 2.5 (Indian) with baseband 1.76, Stock ZUI 3.5 (China) 1.70, Custom ROM (both with 1.76/1.70 baseband).

I see any of the ZUI gives much stable 2300MHz Jio reception where as any custom rom with any baseband (1.70/1.76) is unable to sustain 2300MHz and signal drops back to slower 1800 Mhz or even further down to 850 MHz. Switching to ZUI (QFIL flash) instantly solves the issue and phone is able to maintain stable 2300 Mhz link.

Frankly speaking, even with fluctuating network of Custom ROM, there are no call drops and internet speed is acceptable, so it is manageable. Not sure if this fluctuation effects battery life or not.

I am with a 75 mbps wired cable connection. Usually at off peak hours the connection tops at around 80-85 mbps.

As I wrote above, switching to ZUI (QPST Flash) immediately allows my phone to have a 150 mbps link. Where as with any custom ROM the 2.4G WiFi link is limited to 72 mbps only.

I have tried this with 4 different routers (TP-Link / D-Link and couple of Tenda). Same results.

Tried two custom rom and few kernel like AR Beast or Heliox but the results are same with both.

Any of the ZUI, regardless of Indian or Chinese doesn't have this issue.

Pardon me. Didn't notice this earlier. You are on Nougat (7.x) ROM. My entire custom rom experience so fas has been with Oreo (8.x).

May be it has something to do with that ?
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] vuckovic_stefan:
I'm using my phone only on 1800 mhz because my provider is using this and 800mhz (band 20).

So I can speak only for 1800 mhz. It definitely improved, I don't see signal fluctuations as before.

I think you have another problem because you have available 3 frequency ranges. I saw for your network just the 2 (2300 and 1800) BTW.

As you say I also didn't have some big problems, maybe it could cause a little more battery consumption. After latest 5.4 AEX I began to loose data connection from time to time on 10 seconds. With newest baseband I didn't saw that also, I'm using it half day, we will see in future how it will go.

As I can conclude it depends form device to device, don't know why, maybe it's something in manufacturing.

For someone this works and for someone that.

Update!

I just tested wifi and it connects to 150 Mbps without any problem! See the proof.

I see you went few times to stock rom so that didn't help you, don't know what to recommend except to use ZUI Oreo. You have that deodexed version form hendibudi
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] vuckovic_stefan:

[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] NaXal:
[MENTION=6596602]vuckovic_stefan[/MENTION]

Thanks for your reply. I haven't tried AEX yet, so have to try and check if I get 150 mbps WiFi link there.

Regarding VoLTE link, yes, I already wrote, 1800 MHz works fine, but no stable 2300 MHz reception.

Regarding Jio, there are difference frequency available in different telecom circle of India. For my region, we have 3 (2300/1800/850).

Need a newbie type guide for this new treble stuff and how to switch back to stock bootloader locked ZUI 2.5 for warranty purpose. I already know how to do the same with non treble older ROM, like RR or PE but not sure with treble ROM.

I doubt hardware is the issue here. Something I am not doing right with software which I feel causing the issue. Anyway, attempting to switch to AEX to check.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] GNVT:
I can confirm that this is safe to flash over 1.6xxx firmware.

First boot will turn led on with vibration, just force reboot.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] NaXal:
Pardon me, while I was downloading AEX, I noticed that you are on a much older build, infact 4.5 is a Nougat build.

I have never tested this with any Nougat Custom ROM.

Have you seen similar results on LTE/WiFi with Oreo custom build ?
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] vuckovic_stefan:
Sorry 4.5 was typing mistake.

I am using 5.4 latest treble Oreo rom.

https://xdaforums.com/lenovo-zuk-z2/how-to/z2plus-treble-roms-flashing-reverting-t3778287

This is the guide, very simple. For treble rom you need new TWRP and factory2vendor zip (this you flash with old TWRP than you flash new TWRP reboot recovery and install rom)

For reverting you just need to wipe everything, flash vendor2factory and flash whatever non treble rom you like.

If you are familiar with qfil, flash Zui 3.5, activate Volte, flash latest AEX Oreo and you are good to go.

Just follow procedure and everything will be just fine.

Same procedure for stock rom. Flash vendor2factory, wipe everything, flash stock rom via qfil.

I think 2.5 doesn't lock bootloader, 1.9 does.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] NaXal:
[MENTION=6596602]vuckovic_stefan[/MENTION]

Thanks for your time and replies.

I have got the AEX 5.4 latest one installed. WiFi problem is solved with this baseband for sure. Out of three CR I have tried, namely, Pixel ROM, Reconstruction Remix and AEX, it is AEX only where I have a 150 mbps 2.4G WiFi link.

Jio still struggling with 2300 MHz, but it is way to early too make a definitive comment since need to wait a day or two for full picture.

I have one more question with this new treble setup, asked you before, sorry, asking you again too. Just to be double sure before I do anything since there is always a risk of bricking and breaking things.

From this treble AEX, if I wish to return back to full stock, like bootloader locked / stock recovery / stock ROM, simply QFIL Chinese 1.9 would do right? As with previous non treble Custom ROM, the process was to QFIL 1.9 flash and all back to bone stock.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] vuckovic_stefan:
I'm glad you solved your problem with wifi. Hope to be true for mobile signal also!

You have to flash vendor2factory zip and than you can go back to stock rom or any custom non treble build.

Of course whenever you change rom (stock to custom, custom to stock) you need to clean everything (cache, dalvik, system, data).
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] NaXal:
Just asking, with fact2vendor flash, TWRP shows a new partition while wipe, that is vendor. For installation for another Treble ROM, do I need to wipe this vendor partition also along with cache/dalvik/system/data).

Thanks a lot for your comment and help !!
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] vuckovic_stefan:
Vendor partition contains HALs from stock ZUI 337. At least on AEX rom. Oreo is capable of using those hals, so the update can be done much faster and any treble system image can be flashed and everything should work. Really great progress from Google :).

If you ask me for AICP or some other Zuk Z2 rom they they also come with vendor HALs. You can wipe and install but if everything is the same you don't need that.

I wiped, when I was installing latest AEX 5.4 :), probably it was not needed. But I like it that way :).

Nothing man I'm glad I could help somehow.

1. Can i flash this when using AEX NOGUT ? (AEX 4.6)

2. Will it break Volte ? Ie. Do i have to reflash stock to enable volte ?

3. Can i flash using TWRP 3.2?
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] Andro Enthusiast:
1. Yes. You can flash.

2. It doesn't break Volte as per many users who have flashed this. But do take a back up of EFS partition in TWRP. In the worst possible case when volte is broken and restoring EFS doesn't make it work again, you have to flash stock to enable volte.

3. Yes. You can flash using the latest official TWRP 3.2.1 or the Treble TWRP.

[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] NaXal:
Well it's been a full day of use with AEX and 1.70 baseband with my network. That is Jio India.

Facing call drop issues with VoLTE Jio connection.

Earlier with RR ROM and PE, reception issue meant switching down to 1800/850 MHz with weaker reception but after a days use, I see AEX holds to this 2300 MHz much longer, even with poor reception. Not sure if that is causing the call drops.

On contrast, I still feel stock ZUI had much better reception compare to three ROM I have tried. Namely, RR, PE and AEX. Out of this 3, AEX has the stronger WiFi performance. Other 2 were limited to 72 Mbps. Network reception is some what same with all 3. Didn't see considerable improvement with ZUI 3.5.33x baseband compare to ZUI itself.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] sonarkrishna:
Is it safe to upgrade baseband or not..becoz most the people facing call drops on Jio volte...so I feel safe on Indian baseband 1.76...if further developments r done on baseband then I think to upgrade but now it's unsafe
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] NaXal:
There isn't much difference I saw between 1.76 and 1.70.

ZUI is stable regardless of the baseband (1.70/1.76). Custom ROM shows different results for some people here.

I have seen in my case, VoLTE reception issue is present in all custom ROM regardless of baseband. But not much of call drops.

AEX out of three (RR/PE/AEX) I have tried has best WiFi reception. Again, regardless of baseband between 1.70/1.76.

Reading by comments it seems some people have benefited from 1.70. but that is not me for sure.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] sonarkrishna:

[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] Andro Enthusiast:
You can flash it over 2.0 baseband as per [MENTION=7174278]kubersharma[/MENTION] who made this zip. In worst case, if you face issues, you can flash the 2.0 baseband zip again and get back that baseband. Do take a back up of EFS partition in TWRP also.

So its mostly safe to flash in your case and its worth as you get Oreo Firmware for Oreo Custom ROMs along with Oreo Baseband !
