Z2 plus doesn't respond in fastboot - Lenovo ZUK Z2 (Plus) Questions & Answers

I have a z2 plus with aicp rom flashed on it. I wanted to flash a different rom so I went into twrp to wipe data but I don't know what I did but it ended up not booting up into twrp at all. Choosing recovery mode boots into fastboot and fastboot doesn't respond in my computer ( Although the phone does boot back into aicp and responds to adb commands ). Tried installing a bunch of drivers from different sites, nothing works. Any help will be appreciated.

I can flash a rom and gapps, but it still boots to TWRP 3.0.1 recovery. Any ideas?

I was given a bad kindle fire hd 8.9 that failed a factory update and was stuck in a factory boot loop with restore options that didn't work. I have done a lot of work on it and have gotten it to the point where I have TWRP 3.0.1 on it and I think I have the drivers working correctly. It shows up in device manager, fastboot works, and I can transfer files via windows explorer over to it. I can flash a rom via twrp after dragging files to it in windows explorer, but after flashing ResurrectionRemix-M-v5.6.9-20160528-jem.zip and open_gapps-arm-6.0-nano-20160605.zip it just reboots back into TWRP. I have tried to use the 2nd bootloader thread and did the following:
fastboot -i 0x1949 flash bootloader kfhd8-u-boot-prod-8.1.4.bin
fastboot -i 0x1949 flash boot kfhd8-freedom-boot-8.4.6.img
and I already have TWRP 3.0.1, so I didn't re-flash that. After that, within TWRP, I flash the resurrection remix rom and gapps, but it boots back to TWRP when I reboot it after a successfull rom install. Any ideas? Thanks!
Never mind. It booted successfully after several reboots with it going to recovery. Not sure why it took that many reboots or power cycles to boot.

My OP3 won´t boot into recovery even after flashing stock image via fastboot

Hello everyone,
i think my OP3 is bricked, cuz after i wanted to install new custom ROM with TWRP it went south. When I swiped to install the ROM it showed, it´s corrupt so i wanted so i wanted to push some other .zip to the phone through adb, but no device showed after adb devices or fastboot devices in fastboot. So I tried restore phone from backup i had via TWRP and the phone just wouldnt boot. Oneplus logo showed for a few seconds then it disappears and phone goes dark. Have to hold start button for 10 sec for hard restart phone and then i can go only to fastboot (now it will show fastboot devices in command line). Recovery won´t boot. Tried flashing stock recovery, some versions of TWRP and still just OP logo and dark.
Thanks for every help.
I think for:
fastboot -w
fastboot flash recovery recovery_of_ur_choice.img
on flashboot mode obviously ^^
With that, u must have access to twrp

Help me please :( LineageOS bricked my phone :(

Hello guys
I have a problem
Description:
I have ZUK Z2 and its great phone. I installed latest LineageOS ROM which have OTA updates and yesterday prompt a comunicate that I can update my phone so i clicked to upgrade. But then system is not launching and there is only twrp mode so it's bricked i tried to restore my phone with method described here but it did't work :/ QFIL says" Download Fail: Sahara Fail: QSahara Server Fail: Name of directory is invaid (last one I translated because it was written in my native language). I checked FAQ and i restarted my computer and phone, i changed name of directory to ZUK and it still doesn't work :/ Then I found that ulocked bootloader may be a problem so I tried to lock it but it doesn't work either :/ i wrote adb reboot bootloader and my phone runs fastboot mode but command "fastboot oem lock" don't work, it says only "waiting for device" and nothing happenes :/
Could you help me to unbrick my phone? i'm very desperate
Since you can enter the recovery mode go to mainscreen of twrp, wipe system, data, dalvik etc (but do not wipe internal storage!!!) and then install again lineage, google apps, and addon superuser (in case you want root)...
Regarding QFIL method. I have flashed twice the ZUK orginal software with unlocked bootlader and the bootlader remains unlocked also after the flash. I guess you cannot flash with QFIL and you get the Sahara notice because it is either:
+ you have installed the wrong ZUK drivers or
+ the rom folder name is too long or it is something else.
QFIL method will wipe your entire phone though. So i would try first to wipe with twrp and if it does not work then try QFIL.

I tried to flash ROMs via twrp like you wrote but still only TWRP starts and nothing else happens :/
Hi, what if I cannot get the the phone connected to CFIL? It always starts into twrp as soon as the phone is connected to the PC and it doesnt matter what buttons I keeped pressed.....
You wrote it wrong, when you try fastboot you need to use "fastboot -i 0x2b4c" otherwise it judt wont work and will always showing "waiting for device" hope you can get futher now.
Sorry, I dont got your point...
Hi
Head for zukfans.eu
Theres a thread and plenty of guides
Yes, there are guides but no one works for me so I came here for help :/ i'm desperate and i don't know what to do now :/
Are you able to boot into twrp? If yes, then wipe system, data, cache and flash rom again. If not, then boot into fastboot mode by holding down both volume button and connect your phone to PC. Once you're in the fastboot mode you have to flash recovery using the
Code:
fastboot -i 0x2b4c flash recovery <recoveryname.img>
, after flashing boot into recovery and allow for system modifications if a dialogue pops up and flash any custom rom with latest gapps (but you still need to wipe system and data) .
This worked for me on the advice of one of the users at zukfans:
Go to TWRP recovery terminal commands, and enter the following:
dd if=/dev/zero of=/dev/block/platform/soc/7464900.sdhci/by-name/misc

Unable to flash TWRP via fastboot

Hello, I have a huuuuge problem.
Every time I try to flash TWRP through cmd, nothing happenes. I have all needed files, my phone is being recognized in adb devices, reboots on command, is on fastboot devices list, reboots on fastboot reboot command, but it totally do nothing when I use fastboot flash recovery twrp.img command. Maybe it's my drivers fault, because last time i uninstalled my device through Device Manager, somehow it worked and I flashed TWRP. But then I switched to MIUI and as expected TWRP was removed. And I cannot flash it, please help
Did you update to latest MIUI?
Yes, right now I'm on Global Stable.
Turn your pc into a new one then you will.
Why turn your PC into a new one? resetting?
Isn´t there another solution?
Removes old data such as adb,platformtool, twrp.then can do it.I've come across and solved this way Do not know why
xx
Posted another tread:
I struggled a lot installing TWRP. I did not succeed flashing TWRP from my PC. My solution was:
Starting up TWRP: fastboot boot twrp.img / boot command only boot and does not flash.
Thereafter installed Magisk 17.1 from TWRP for rooting
Thereafter flashed TWRP / I tested flashing both by using Flashify and TWTP Manager and both worked.
Maybe by using Flashify I had to use an older version of TWRP. Think TWRP Manager let me install 3.2.3-0 direct without problems.

Question I messed up my android recovery

Yesterday i was trying to flash a pixel experience rom on my poco f3 but i was stupid enough to flash it while still in my custom rom. When i tried to flash the pixel recovery it didn't work so i tried doing it again and my phone didn't boot.
It was completely dead , i tried numerous ways but all of them failed .But when i tried holding down both power volume and power button it somehow turned on straight to arrow os. But now when i try booting into recovery mode it straight up boots into the system .I figured that my recovery was messed up so i tried installing twrp through fast boot mode. My phone goes into fastboot mode fine but it doesnot get recognized by my pc .
Get Mi Flash, and install the USB drivers in there.
Then you should be able to do "fastboot boot twrp.img" or the equivalent for OrangeFox.
Make sure to use TWRP or OrangeFox that support Android 12/13 !!!
If you use Windows PowerShell instead of CMD, do "./fastboot boot twrp.img" so basically add "/." before command.
Once in Custom Recovery, install the RamDisk.
Get Full MIUI Recovery ZIP from xiaomifirmwareupdater.com and flash it in Recovery, and then wipe data.
Boot system, then boot back into TWRP/OF and flash your Custom ROM of choice and wipe data afterwards.
Thanks seems like i had some drivers missing i installed twrp and it is working great. Thank you for your time
