Fastboot isn't working right - Zuk Z1 Q&A, Help & Troubleshooting

Hello,
my phone has the problem that when i enter fastboot and try to unlock it with "fastboot -i 0x2b4c flashing unlock" it only says "..." and doesn't do anything - for hours.
so is there a way to reset the fastboot mode? (i have the correct driver on the pc and it finds it under devices with "fastboot -i 0x2b4c devices")

The right command is fastboot -i 0x2b4c oem unlock-go
You could also use one of the toolboxes.

Thank you, problem solved!

[HELP] Device starts direct on Fastboot

I believe this happened after the various modifications I made, I am currently in stock 7.0, whenever I switch off the phone and start again it sends me directly to the Fastboot screen, as if I was calling it with Power + Volume Down, I would like To know what I can do to solve this

Usually happens when you don't give the clear fb mode command while flashing a stock ROM via fastboot.
I dunno if you need to reflash, but you need to give that command to your phone so it doesn't boot to FB mode.

This is maybe due to corrupted rom. Do a factory reset. If you still face any problems install rom via fastboot

Would you help me? First I installed the MPJ24.139-63 (6.0.1) build and used the following command line:
Fastboot flash partition gpt.bin
Fastboot flash bootloader bootloader.img
Fastboot flash logo logobin
Fastboot flash boot boot.img
Fastboot flash recovery recovery.img
Fastboot flash dsp adspso.bin
Fastboot flash oem oem.img
Fastboot flash system system.img_sparsechunk.0
Fastboot flash system system.img_sparsechunk.1
Fastboot flash system system.img_sparsechunk.2
Fastboot flash system system.img_sparsechunk.3
Fastboot flash system system.img_sparsechunk.4
Fastboot flash system system.img_sparsechunk.5
Fastboot flash system system.img_sparsechunk.6
Fastboot flash system system.img_sparsechunk.7
Fastboot flash modem NON-HLOS.bin
Fastboot erase modemst1
Fastboot erase modemst2
Fastboot flash fsg fsg.mbn
Fastboot erase cache
Fastboot erase userdata
Fastboot erase customize
Fastboot erase clogo
Fastboot reboot
What command line should I add to resolve this problem? I will reinstall that same build and then put the Nougat build.

fastboot oem fb_mode_clear
This isn't my script - it's from the run.bat file elsewhere on XDA, note the fastboot oem fb_mode_clear at the bottom. I'll try to find the source to that run.bat and link it, I've used that to reflash MM 139-63/64 and use that same system to upgrade to Nougat with no problems.

Fastboot oem fb_mode_set and Fastboot oem fb_mode_clear they worked for me, thanks a lot.

You connect to PC, mount sdcard with twrp and copy a rom from pc to your sdcard. Then install the rom within twrp.

Helloo. I don't have sdcard neither otg. is there any other option? I've tried using adb sideload but still only boot to TWRP.
Go to twrp> Reboot> Bootloader
You'll then reboot into the fastboot mode.
Connect your USB-C Type cable and make sure that the device is connected.
Make sure that you have the stock COS 12.1 ROM in your adb folder and use these commands-
fastboot -i 0x2b4c flash modem NON-HLOS.bin
fastboot -i 0x2b4c flash sbl1 sbl1.mbn
fastboot -i 0x2b4c flash dbi sdi.mbn
fastboot -i 0x2b4c flash aboot emmc_appsboot.mbn
fastboot -i 0x2b4c flash rpm rpm.mbn
fastboot -i 0x2b4c flash splash splash.img
fastboot -i 0x2b4c flash tz tz.mbn
fastboot -i 0x2b4c flash boot boot.img
fastboot -i 0x2b4c flash recovery recovery.img
fastboot -i 0x2b4c flash cache cache.img

fastboot -i 0x2b4c flash persist persist.img
fastboot -i 0x2b4c flash system system.img -S 1G
fastboot -i 0x2b4c reboot
Take a otg and copy ROM and select file from twrp

ZTE Blade S7 impossible to unlock ("fastboot oem unlock" is an unknown command)...

ZTE Blade S7 impossible to unlock ("fastboot oem unlock" is an unknown command)...
Hi all,
I tried to unlock the bootloader of my ZTE Blade S7, but had no luck.
Followed some similar guides in Internet basically.
When I reboot into the bootloader, I issue "fastboot devices" and I can get the correct information below.
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot devices
bd9bc873 fastboot
Instead when I try to issue the "fastboot oem unlock" command I get the error message below.
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem unlock
...
FAILED (remote: unknown command)
finished. total time: 0.000s
I tried also with "fastboot oem unlock-go" and "fastboot oem device-info", but they did not work too.
I allowed the "OEM Unlock" option of course.
Any ideas?
Thanks in advance.
Emanuele
same
I'd look through the source code to see what commands it has.
