Thank you so much for your work :D

I have just moved to the Snapdragon world from MediaTek with the Z2 Plus being my first Qualcomm device. I was always fascinated by the level of development that happens to Snapdragon devices. MediaTek is just too shy to be open I guess. But now i am really nervous as it has just been a week with my new device and I am already unlocking my bootloader to load Jaguar as many have suggested (thanks to all of them for their time as well). i just don't know how to handle this new environment in case something goes wrong. But seeing this community being so active, I could find courage to proceed, knowing deep down that i will get help as I very much stick to the instructions and check my steps at least twice before proceeding but I can be stupid sometimes to misunderstand instructions and often land in the "problem" territory. I just wish to be getting a hand in case i land there again. :)

Once again, a lot of thanks for your hard work :D

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Battery calibration doesn't do anything, but delete battery stats, which happens anyway when the phone is fully charged and removed from charger or when you clear battery stats manually. You probably did battery calibration when your phone was discharged, so the system is totally confused. Just charge the phone to 100% and remove it from charger...

My Z2 plus was on stock (Indian) . on the purchase date itself it was hanged by showing black screen and led light, it was happened more than 4-5 times.

On next day I unlocked boot loader and flashed aex 5 ROM, then 2 days went without freezing issue .

But yesterday when I woke up my z2 was fezzed with same dark screen sand when I rebooted the battery drained from 65 to 3%.

So I want to know is it software issue or hardware? And of anyone has the solution please share it ASAP

If you're using uc browser why are you using Jaguar? Jaguar is security based, do you not know what uc is?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] doveman:
Thanks, that worked and saved me having to cut up a cable or mess with QFIL. It did automatically boot to TWRP and wipe my data though (it said something like "wiping data without wiping data/media") but that doesn't really matter.

EDIT: Actually, after booting it seems all my files are still there, so I don't know what that process did.

I really need to wipe all the files (on "internal" I guess) though, as I'm giving this phone to my Mum and there's a load of junk on it. I could just delete all the folders manually but there's one "Android" with data, media and obb subfolders that I'm not sure it's safe to delete. The data subfolder has a load of folders for apps that were installed but aren't now that I've wiped and changed ROM, so there's no point those being there but in amongst them I think there will be folders for apps that are installed by default in Jaguar.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] function06:
Ya i just was accustomed to the features of uc which are pretty good, mainly the download manager which is better than any other browser.

But have just uninstalled it yesterday and started using yu browser.:svetius:
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
You should be ok deleting that folder, as it should be regenerated on boot. To be safe, just save it on PC.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] MtBlackstar:
For download manager use ADM works great with resume features and more .

For browser I would suggest xbrowser dosent have ads and has ad block and mark ad features so no white space ( ad left over space ) and instant translation

Mainly the size is 700KB only so its easy on ram and storage

Or go with Firefox
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] doveman:
OK, thanks. After backing up the Android folder, to make sure I'd erased everything off the storage (presumably what is labelled internal), I encrypted it and then did a Factory reset, as this should make any data unrecoverable but it rebooted into TWRP, asked for my encryption password and then did the "Wiping data excluding data/media" thing again, which left all the files on the storage intact.

So it seems that TWRP is intercepting the Factory Reset, which I think would normally just delete the encryption key to make the storage unreadable, or maybe format the partition but the result is the same either way. How can I (safely) force it to do that, so that I can start with a clean storage/internal?

Incidentally I noticed that when I encrypted storage it had to reboot and took about 10-15 minutes, which has been my experience with other phones but with my new Redmi Note 4 when I encrypted it, it didn't need to reboot and it finished almost instantly. Does this mean that the Z2 doesn't have hardware encryption/decryption and the Note 4 does or is there some other reason for this difference?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
You should never do factory reset on the phone. Only in TWRP. You can boot into twrp and when presented with a password prompt, select cancel and then do factory reset. This way everything will be formatted. Or you can mount data with the password and then do factory reset, as opposed to advanced wipe.

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] doveman:
OK cool, I did the factory reset in TWRP and it's all clear now.

I've flashed Magisk and it shows v12 installed in Magisk Manager but it also says "Not rooted" and so I can't run/configure Afwall+ (I've installed it) and Magisk Manager says "No internet" when checking for updates, presumably because Afwall isn't allowing it through.

I used a guide for Z2 pro, which stated it's the same for Z2.

No sahara errors, but it says the device is no longer on port 8. I have an old laptop with windows 7 and all my other PCs have linux. Flashing doesn't work with virtual machine

I didn't flash the 3.5 rom, but rather made a separate firmware zip, as I have done with other releases.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] user.system:
Perhaps try a different USB port and or cable if you haven't already. Maybe power management suspending a usb port; try updating windows, drivers etc. -- unlikely to help; Shorten the filepath for the qpst files as much as much as possible (e.g. c:/rom); might be that it only flashes the short files (which are listed first in rawprogrammers.xml e.g. xbl.elf, tz.mbn etc .. and then the ones with longer name e.g. system_1.img. And if you are right at the threshold of file path length where qfil bales out, ... well.

--

Did you forget to reboot to bootloader after flashing the firmware to check lockstate? I.e. is it bricked or might it just have been relocked (was just about to build and flash that firmware myself)? Since at some point I still managed to boot into bootloader mode on a locked device with a key kombination, plugging/unplugging the cable and what not; not sure which. Anyways might be worth a try in that case.

OK, I just reinstalled Magisk from TWRP and it's OK now.

I noticed when doing a backup that there's a partition "System Image (3072MB)". What's that? I'm just wondering if it's wasting space? The actual System partition is only 2049MB.

When I connect to WiFi it says "Connected, no Internet" but all my apps can connect to the Internet, so any ideas about that?

I'm thinking that it might be because something is blocked in AFWall+ that needs access, although I can't recall having this problem on other phones. I won't type out all the apps, just the things that are more system related which I've allowed WiFi access for:

(kernel) - Linux kernel

(ntp) - Internet time servers

(shell) - Linux shell

(tethering) - DHCP+DNS services

(vpn) - VPN networking

AfWall+

Calendar

Calendar Storage (not sure if this is needed or if just Calendar is enough)

CaptivePortalLogin (I think this is needed when logging into public WiFi)

Google Contacts Sync

Google Partner Set Up

Google Play services, Google Services Framework, Google Account Manager, Google Backup Transport

Market Feedback Agent

Media Storage, Download Manager, Downloads, MTP Host

Things I haven't allowed yet which maybe I need to (I don't really know what most of these are/do):

(drm) - Digital Rights Management service

(gps) - GPS

(root) - Apps running as root

ConfigUpdater

Device Health Services

Intent Filter Verification Service

PacProcessor

ProxyHandler

Setup Wizard

Work profile setup

ZukDoze, ZukPocketMode, Android System, TimeKeepReceiver, Settings Storage, Input Devices, Slim Settings Storage, slim, Call Management, Key Chain, ANT HAL Service, Setttings, SlimSettings, com.android.wallpaperbackup, Fused Location

I want to change the encryption password so it's different from my unlock code.

I've tried this cryptfs app which I've used before https://play.google.com/store/apps/details?id=org.nick.cryptfs.passwdmanager but it doesn't seem to work with Magisk, as it says "Cannot get superuser access, exiting". I'd rather not have to install SuperSU just to do this as I'll probably end up breaking the phone again!

I've also tried this method https://www.xda-developers.com/how-to-manually-change-your-android-encryption-password/ using "adb shell", then "vdc cryptfs changepw password <yournewpass>" but it says "error connecting to cryptd: Permission denied".
