Reverting to stock ZUI - Lenovo ZUK Z2 (Plus) Questions & Answers

So I have had this issue since the beginning that I can't restore rom backups I make via twrp. I asked on some threads about it but nothing helped. Now I'm thinking I'll start from scratch and try my luck. But when I used qfil to flash the Z2132_EN_OPEN_USER_Q01080.2_N_ZUI_2.5.104_ST_170418_qpst rom I didn't succeed because of the error saying "Firehose fail". I looked this up and I read somewhere that qfil is mostly for when your device is hard bricked.
Is that right? If not then can somebody guide me through the process?
I basically want to restore stock ZUI with all partitions as they were out of the box. All this to make twrp backups work properly.

[Sprint] CWM - Error while recovering /data!

Hi all,
Sorry in advance if someone else has posted this. I tried searching for this issue within this forum and I cannot find an answer.
When I try to recover from an nandroid backup, I keep getting "error while recovering from /data!". I cannot find an solution. It started with CWM 5.5.0.3 with stock rom. Then I flashed to blazer rom 1.4 using CWM 5.5.0.4 and the issue still exists. I played with the domination theme, didn't like it and tried to nandroid back. I had to redo my entire phone.
I tried recovering multiple times, flashing blazer rom then recover. I tried doing advance recover just the data partition. I tried flashing CWM 5.8.5.7 (or something) from the development thread and recover from that. Nothing works. When I did the backup on stock and blazer, there wasn't an errors. I also tried moving the backup folder between internal and extSdCard.
Any ideas? I'm currently afraid to try an other ROMs or play around with my phone because it takes me at least an hour each time to recover from flashing.

[Q] Please Help LG G3 D850

I tried flashing a rom into my phone.
It didn't work and I wanted to restore from the backup I made from TWRP.
I restored my original OS from TWRP, and it's booting up to it, but once it gets to my lockscreen and after a minute or so, it reboots. This happens every single time. Does anyone have any ideas of what to do?
Something is false with backup I would say.
Flash stock firmware, root it again and then play with custom rom again.
Since, I'm relatively new at flashing. I just want to make sure I am doing this correct.
So I can get the stock firmware from this site:
lgg3root (turns out I can't post the url yet since I'm a new user)
Then I would have to choose the ADB sideload option in TWRP since there would be no other way for me to flash it correct?
Also would flashing the stock firmware delete everything in my internal storage?

Put my original nandroid backup back on, but now issues.

I am just tired of wiping, trying a new rom, setting it up, finding problems too big to live with and repeating the process. So I used TWRP to put my backed up system back on the phone but when it boots up tons of things are missing. Google apps are all gone, no root. Did I do something wrong? I backed up all the tick boxes when I made my backups, yet so much is missing?
Flash th stock through odin. Then flash twrp and this time restore only data from nandroid.

Thanks. I did flash my original firmware just now via odin, but I thought that would resolve my encryption problem. I made a thread about it here, I don't know if you could chime in on that thread if you have any ideas on my new issue?

Can't restore backup through TWRP (bootloop)

Hello. I wanted to try out some custom ROMs for this phone few weeks ago but before flashing anything I did a backup of stock ROM in TWRP on external SD card. I used this backup once back then and it was working but now, after few weeks on custom ROM, I can't restore it properly anymore. Restoring process in TWRP goes as expected, without any errors, but when I want to boot system it goes into bootloop.
Anything can be done to fix it assuming the backup itself isn't corrupted? I don't know what else details might be relevant here.

Question How does restoring work in this phone?

For context, I want to clear up a few things before trying to root so I don't end up bricking the phone.
So after reading a few threads it seems even recovering via twrp is messed up in this phone. Can someone shed some light on this matter?
Can I restore system, data, and boot partitions via twrp in case something goes wrong (while staying on official miui roms everytime, I don't intend to install custom roms) and I have to revert the phone back to the state it was in at the time of a backup?
It feels like at the very least we would be required to re-flash the entire firmware via mi flash tool and then restore whatever is needed via twrp later. Will this work?
Also I hear using twrp to install the official firmware is not a good idea, what's that about?
I know long post and a lot of questions, so please bear with me.
Thanks.
Custom ROMs and Stock ROMs differ in one aspect, which partitions are left untouched. Since stock ROM is a lot more invasive and formats all partitions, official flash method is recommended.
When you mess things up, mi flash tool is safest option. Its safe to experiment, backup, restore on boot+system+data in TWRP across ROM installs but don't mess up recovery partition. Remember to format data between ROM installs unless dirty flashing on same android version
