Just tried getting the Pixel nav buttons, phone is messed up now - Lenovo ZUK Z2 (Plus) Questions & Answers

I tried downloading the Pixel nav buttons just for kicks, now the system UI stopped working and I don't know how to remove the Pixel nav buttons. I have TWRP recovery installed so I could wipe, but I'm not sure what to wipe. Phone is rooted with LineageOS nougat.

It should have wiped any apps installed as a user. Was it installed as a system app?
Download the rom and start over with a clean install.

I am not sure if I installed as a system app, I went to downloads and i flashed the zip.though I would assume it installed itself as one since it is code the system UI uses.
So I wipe the internal storage or system?

If you did any flashing then yes it definitely installed to the system.
Download the rom and reflash should restore your system.

[Q] Backup in Recovery

I've done a fresh install of a ROM, done all my settings, installed my apps/ringtones and removed some system apps.
If I do a backup now in recovery mode, will this do a full restore including all above changes?

Have heard a few things about needing an Odin firmware downgrade. Is that necessary with my firmware? And should I use Odin, or ADB?
Really appreciate the info. I want to tinker, but without working recovery, I'm a bit Leary.

You need to wipe cache, davik cache and data, then flash the rom.

Hi,
This post saved me, I installed TWRP 2.8 and my system froze, I couldn't get past the Samsung 10.1 screen.
But found this post and flashed 2.6.3.3 via Odin and it all went smoothly.
PS Goo.img.com dosen't have the files anymore

I currently have no recovery. I tried flashing 2.8 originally.
How would i clear cache, data, and all before trying to flash 2631?

No, you flash TWRP 2631, then boot into the twrp then select advance then put a check for cache, davik cache and data, then swipe. Once done just flash your rom. I would copy the rom to the download folder on the internal storage (/sdcard/download/) before flash your new twrp.
Is 2.6.3.3 more reliable / stable in terms of making / restoring nandroids? I just got my new Note last week (p607t) and flashed xKat with TWRP at one point, restoring apps from (some with data to avoid re-entering account info or redoing complex settings...) I have had one problem however, when I was almost done restoring, I noticed that I was getting fc's, particularly with games that required an internet connection. I wiped dalvik and cache in TWRP, then hit fix permissions, which I think screwed everything up (maybe due to the bootloader / firmware base mismatch). Anyway, my most recent nandroid was with the fresh xKat install, but fixing permissions caused this weird "hot"-bootloop where it skipped the boot animation but start loading immediately after rebooting, but then freezing before all boot tasks had completed (ex. some optimizations on boot with Android Tuner Pro, FolderMount mounting folders, loading xposed modules...)
Not wanting to re-restore, I first just tried dirty-flashing the ROM again (only wiped dalvik and cache, but did something I hadn't tried before: in the wipe menu I hit "repair partition" for system and data, pre-flash). Luckily it worked and set everything straight... but just want to make sure, 2.6.3.3 is still recommended as the most stable version (in my experience, fixing permissions in recovery can be very hit or miss on any version)?
2 questions before I roll back my recovery, I think these "killer features" (totally serious, #2 has been huge since I got a couple of the newish flash drives with micro usb on one side and regular usb on the other) of TWRP were implemented in 2.6.3.3, but just want to make sure: can you 1) compress nandroids and 2) mount a USB OTG drive and flash from or backup to it? Thanks all, really loving my new Note (massive upgrade from my Note 8!)

I HAVE flashed 2631 for the qualcomm lte.
I've done or several times since you told me that's the best version.
IT WILL NOT BOOT INTO TWRP. it's a scrambled screen. That's all. No touch options. No check boxes. After a minute, tablet reboots itself. I am on stock firmware still. Rooted.
Maybe I should just try CWM. never had this much problems with twrp on any other device.

How about wipe cache/davikcache/data with your stock recovery (just reflash your stock recovery). After that let it boot up, then power down and flash twrp. Once done, don't boot up, boot back to twrp . Let me know how it goes.
Cool. I can try that when I get home. Do you have a link handy for the stock recovery?

Unable To Properly Install Pure Nexus Nougat & Nandroid Not Working

Hi! I went into the latest TWRP recovery with unlocked bootloader, and I wiped system, cache, dalvik and data. Then I flashed the proper vendor image, the ROM zip, Gapps and then Elemental X kernel. However, when I reboot, it just boots me into TWRP recovery. I have tried wiping dalvik cache and cache. I then tried restoring a nandroid, but it just got stuck on the Google screen. Didn't even get to the colored dots screen. I ended up flashing factory image, but I would like to get my Nandroids working and this ROM. Please help! Thanks
I'm no expert but I think it might be happening because of encryption. Did you disable encryption before doing all this stuff?

Encryption in stock Android? As far as I know, I can't turn it off. It says that the device is encrypted in settings. I think nougat forces encryption.
Unless maybe there's a patched kernel that can do that?

I dont think is your problem , im encrypted and never have issues with twrp! Never!! What version of twrp you running? Theres an unofficial kicking around that is much better than official! Maybe you got a bad download! I would redownload all, find and download unofficial twrp 3.0.2.3 I believe. Let your phone boot before you flash custom kernel, thats always worked great for me. The latest official twrps 3022 and 3021 both have nandroid restore issues as well efs restore issues that could ruin your day

What's the difference between wipe and format? On TWRP there is only WIPE for all partitions, but a format data button.

Wipe just deletes all data on the partition. Format makes the partition again, therefore it removes encryption, repairs potential problems etc. Format data has dedicated button in TWRP, for formatting System go to Advanced Wipe, check system, tap on Partition details, check EXT4 and perform format.

A Thought
Dunno if this will help, but whenever I flash a ROM/kernel combo, I always flash the ROM/gapps, boot up with whatever kernel is included in ROM to make sure it boots properly, and then after successful boot flash EX kernel through TWRP.
OK, so I formatted DATA and SYSTEM, and I wiped CACHE and DALVIK. I then flashed the proper vendor image, pushing it to the device with adb push, and then adb sideload for the pure nexus ROM. It's currently installing. Then, I will adb sideload the gapps ZIP file. Then I'll reboot and see if it worked
EDIT: It just said "No OS installed"
EDIT 2: Just flashed the ROM again, and it is showing the boot animation. This time I did not do Gapps. I also wiped and formatted everything again. Hope all goes well.
EDIT 3: The ROM booted fine. Glad all is working now

So I had flashed the ROM with no Google Apps or anything, just the ROM. But when I add a Google Account, I can't because it says Google Play Services has stopped. I just noticed that the build number is one of a Nexus 6P, and the vendor image is different, the one I manually flashed.

H815 Bootloop after battery died

Hey,
So im currently on holiday and dont get back home until the 13th aug.
I was on my phone last night until i ran out of battery and the phone inevitably died. I charge it this morning and the phone is stuck on the boot animation and has a slowly flashing blue led. I do get past the lg bootloader unlocked screen too and the android boot animation runs fine, just never completes. My phone is running bootloader unlocked, twrp recovery and the imperium rom. My model is h815 and s/n is 512 prefix. The battery was running pretty bad so it might be that. Either way it is stuck in bootloop and i am not sure how to approach it. I also have some internal storage that would need backing up if possible.
Cheers for any help
That's a common issue with Imperium ROM, check post #3341 in this thread for example. Just do a clean flash and your system is back again, but sadly you will lose the apps and settings.

Thats interesting, never thought of that. I should be able to backup any files etc from the internal storage using adb right?
Simply dont wipe internal storage, only wipe data, cache, dalvik and system. THe files on your Internal storages not gonna' deleted, just reinstall the apps you had.

Another problem is that i cant boot into twrp recovery using the buttons. It brings me to the stock recovery asking to factory reset. I guess i could just wait until im home and use adb to boot into the twrp recovery.

Yep. That's what it looks like for me too. When you select factory reset, the phone actually restarts into TWRP.
Make sure you actually do have TWRP installed otherwise it will wipe your phone.
You have a custom ROM installed so I assume competence, but there's always a chance

You need to remove all Substratum themes/overlays or you'll likely have problems. Completely uninstall the overlays if you haven't already and do so I'm the future. It's easy to forget but you need to get into the habit of doing so before you update your OS.
Doesn't happen all the time in my experience but can cause problems like yours often enough.

It's always a good idea to start from scratch if you have problems but if for whatever reason that's not ideal then in TWRP tap install and scroll down to the substratum folder and select "SubstratumRescue.zip". Flash that and it will allow to to boot up again.
