Happened to me too, but as night king has already said you need to format internal storage , also i formated data a using the option on side of advanced wipe option in twtp / wipe

Since then when ever I change ROM or update jaguar , i copy the files to other folder and delete the obb folder

Also the files are neither accessible through mtp in twrp or visible in twrp file manager if you copied them through any files manager on ROM and if you copy them to obb folder from twrp then they are not visible from file manager in ROM ?

Go to TWRP -> Advanced -> File Manager. From there you should delete the obb contents.

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] MtBlackstar:
Bro

If you are from any other ROM including zui ( make sure you turned on volte on that rom , of not then flash stock and turn it on )

First flash the r11 ( clean flash by wiping data cache system ..)

Let it Boot and use it for a minute or two

Then flash the latest version ( dirty flash , no need to wipe anything )

You will have no problems

Your current problem is due to

1 Your flashing procedure

2 you have not booted the r11

3 the ROM you came from didn't had the volte turned on

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
You need to flash stock rom and enable volte there. This is because volte modem can only be selected on stock.

And remember: every time you upgrade baseband or do factory reset, your volte modem is unselected. So, you need to flash stock again.

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Ashish9:
I'm on r18

1. Long pressing the volume keys does work but I can't change volume by tapping which used to work in my previous rom (mokee).

2. In QS, the hotspot doesn't say how many clients are connected.

3. I feel the battery performance is quite bad in this rom as compared to my previous one. I would charge only once per day or two earlier (even in stock).

4. Some apps and gapps are still force closing even when accessibility isn't active for any app (9gag, Google camera, keep, play games).

5. Saferynet approved initially but then suddenly stopped.

1- yap, known bug on r18

3- not me, excellent battery

4- not me either... no service enable? strange indeed

5- it happens... my theory about this is when you flash gapps... you have to wait to the play services (silently) updates... and then flash magisk... anyway, if you already got this problem i use to clean cache and data from google play app, restart phone then recheck safetynet. (got it working with magisk 14.0 , and 14.3, probably all editions in between but i didn't check those)

I gave my Mum her nice new Z2 present today, only to run into a rather serious and embarrassing problem. When I put her 3 SIM in it, it doesn't work. Nor does my 3 SIM which I was using in this phone with the stock ROM only recently. I don't have any other network SIMs to try but we need to use 3, as it's the most affordable PAYG option.

I've attached two screenshots showing the problem. When I put the SIM in (I've tried both slots) it pops up "Select SIM card" but there's nothing to select and I can only back out of this screen. In Settings - SIM cards, everything is grayed out, although it recognises that it's a 3 SIM under the Preferred SIM settings. As you can see at the top, it shows a signal and LTE but the signal is constantly switching from 50% or 25% to 0% and if I try and make a call, nothing happens, it just drops straight back to the dialler as soon as I press dial.

I'd be grateful if you could help me urgently as I had to break my Mum's SIM down from a full-sized one to a Nano SIM to fit in the Z2, so I can't just put it back in the old phone and she'll be without a phone at all until I can fix this.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Your sim must be in when you boot on r11. That's the purpose of running it for a minute, so that you can register on the network. Then you should flash dirty r18.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Ayush Kumar Tarun:
For all SoT lovers; this is it with gapps, 4g, 50-60 mins of intensive games(real racing 3, GTA sa, ppsspp etc) and no kernel tweaks.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] doveman:
Ah OK but why can only r11 register the SIM on the network?

Does this mean that if my Mum wanted to change SIM to a different network sometime or even just add a second SIM, I'd have to flash back to r11 to register the new SIM? The main reason she might use a second SIM is if she's on holiday, so she won't get the SIM until she's there and I won't be able to do any flashing for her, so that would be a problem.

Before I flash r11 can I make a TWRP backup of the current system and data, then flash them back after running r11 with the SIM? I assume flashing dirty r18 overwrites everything on system at least, so nothing from r11 will survive on that partition after dirty flash, so restoring the TWRP backup of system should be OK but I'm not sure about data.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
No. Once the sim card is registered on r11, you can do whatever you want (change, remove, etc.) on any later release. Sim is only required, when flashing and booting r11. After that, you should only update by flashing the new release dirty + gapps + magisk.

Don't save data now, because you won't be able to make calls. Once you have done everything properly and on the latest release, then you can save that data for future...

That's weird because the author says it needs the SIM in when booting r11 or it won't work.

Did you flash the Indian firmware and then the Chinese one (without baseband, etc.)?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] The.Night.King:
You can reset counter yourself there's an option in battery tab to do it. Battery wear can be measured with AccuBattery.

That may not work, Jaguar kernel is already there.

Not mandatory to have root. I've never experienced force closes, check if you've give accessibility permission to any app, remove it. The problem with backup restore happens with all ROM, so remove password before backup.

Jaguar O 8.1 will be based either on Omni or Slim. I have tried all O custom roms, and am 100% sure the more useless features a rom has, the less snappy it is and the more battery it uses. That is true even in Jaguar N. I have tried Jaguar earlier releases and they are better on battery. Features, especially related to sensors, as well as wake blocker, alarm blocker and even doze take the most. System is on all the time waiting for gesture input.

Hey dude no worries if u have twrp installed do onething get transferred all your zip files in your computer and wipe off all the internal storage as it is good to go for a neat flash to overcome any glitch.U just then connect your data cable to your PC and transfer the files to your mobile while in twrp recovery and flash wtevr rom u have.But if u don't want to wipe off internal storage u just simply wipe off system ,cache (the top 4 columns and leave the last 2).Thank you.

---------- Post added at 12:45 AM ---------- Previous post was at 12:14 AM ----------

So just a few more things I need to check before this phone is ready for my dear old Mum.

1. When I connect it to USB it defaults to Charging mode. Is there a way to make it default to Transfer files mode to make it simpler?

2. I don't think SafetyNet Check in Magisk is passing completely, as it says Success but underneath it shows a red X next to each of the two options.

3. As I recall, setting the U-Touch button up under the stock ROM was quite straighforward. In Jaguar, under Settings - Navigation - Hardware Buttons it has sections labelled Tap, Home key, Swipe right, Long tap, Swipe left. Each of these has Normal press and Double tap under them (Home key also has Long press), which can be set to various actions. Under "Tap" I have "Normal press" set to Back and "Double tap" set to Recents and they work fine. The rest is a bit confusing though, as there's only one button, so I think "Tap" should have "Single tap" and "Double tap" under it, "Home key" should instead be labelled "Press" and should have "Normal press", "Long press" and "Double press" under it, "Long tap" should only have one setting under it named "Single long tap" (I don't see how you can have a double long tap). Swipe left and right don't seem to work at all but even if I'm just doing something wrong, the "Normal press" and "Double tap" settings under them don't make much sense.

Just using single tap for back, double tap for recents, press for home and double press for camera (or something else) is enough really so I can ignore/disable the other options, it just seems a bit confusing setting it up how it is at the moment.

4. After I got the SIM working I tried to restore some app backups with Titanium Backup. Most worked OK but Apex Launcher and ES File Explorer both had the Install button grayed out and when I clicked cancel it when back but got stuck on the popup saying installing for ages (I think I had to FC it actually). I was able to download these two apps using YALP and the install button wasn't grayed out doing it that way. I had USB Debugging and Install from Unknown Sources enabled.

Incidentally my favourite (and no longer maintained sadly) WiFi Widget is working now. It wasn't before, when the SIM wasn't working but since reflashing it is, which is great as it's really useful to have a widget on the home screen where you can enable/disable WiFi and which shows which WiFi spot you're connected to and the connection speed.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Applications that require special permissions will have install button greyed. You need to press power button twice and after that you can install them. That's Google's security feature. The apps from Yalp had google binaries removed, that's why they installed straight. F-droid doesn't allow closed source things in apps...
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
I didn't calculate anything. These are traditional Qualcomm's values that are used in most roms. If 1500 frequency is not available, then the processor will use the next available one. There is nothing you can do on kernel side to save battery. If you increase delays for switching to higher frequencies, you will have lags. It is simple like that. The cause of excessive battery drain is Gapps and facebook/what'sup type.
