Thanks

Thanks for you quick response. But Im trying to flash lineage OS onto my phone and the installaion guide requires fastboot. My Device is not being found by fastboot so I thought this step is required.

This only installs on the us version. But that's okay, it is not required. Just proceed with TWRP.

not unlocking

I've tried both this and the Tuliptool method multiple times but, when I boot to bootloader it still says device locked at the bottom. What do I do?

locked

"After some testing, it appears that the Axon 7 Mini is not locked in any way. In other words, apparently neither this package nor tuliptool's unlock are required to flash custom ROMs. The only apparent advantage to flashing this is to get access to fastboot, which provides a way to flash a custom boot and recovery (among other things)."

My axon 7 mini is still locked. I can't take a screenshot of it, but the bootloader is locked.

So, let's say I have used the file "axon_mini_unlock.zip" to update the bootloader .... all I have available now is the fast boot bootloader. It does not reboot into recovery, and it does not boot into the ROM. How do I get back to the previous bootloader or recovery. I have tried flashing one or the other, but still the phone is unable to do anything.

Did you ever find a solution? Here's my situation: (US version P852A12)
1. Flashed axon_mini_unlock.zip
2. Device boots, saids "Device software can't be checked for corruption." (I assume this is verity)
3. fastboot oem unlocked

So I now have bootloader unlocked, fastboot flash recovery tulip-twrp-7.1-3.2.3-r2.img or r1 OKAY and finishes, but cannot boot into recovery.
fastboot flash boot tulip-us-7.1.1-b12-boot-noverity.img also OKAY, but neither b12 or b14 allows it to boot. (Still stuck on 5 secs bootloop)

fastboot boot tulip-twrp-7.1-3.2.3-r2.img FAILED (Too many links)
Cannot boot into EDL.

Been at it for past 4 hours, probably read everything on these forums that's related.
fastboot rom b13_fastboot.zip will not flash through fastboot because size is too big.

Any idea why twrp refuses to boot?

Edit:
So for those interested, I got TWRP installed and flashed Lineage. Here's what I did:

Followed instructions from tdm (post #51)

Warning: Do not reboot until all flashes are done/stated otherwise.

1. Unzip B2017G-US-v1.2.0-b14-bootstack.zip to a folder with fastboot& adb
fastboot flash ddr ddr.mbn (this will fail, but here for completeness)
fastboot flash dsp adspso.bin
fastboot flash splash splash.img
fastboot flash rpm rpm.mbn
fastboot flash modem NON-HLOS.bin
fastboot flash tz tz.mbn
fastboot flash hyp hyp.mbn
fastboot flash sbl1 sbl1.mbn
fastboot flash aboot emmc_appsboot.mbn
fastboot flash keymaster keymaster.mbn
fastboot flash cmnlib cmnlib.mbn

2. After the above, you should be on b14 firmware
Now:
fastboot flash recovery tulip-twrp-7.1-3.2.3-r2.img
fastboot flash boot tulip-us-7.1.1-b14-boot-noverity.img

If either recovery or boot flash fails, reflash aboot emmc.appsboot.mbn from axon_mini_unlock.zip so you are not SOL and atleast still have fastboot. (I did not personally test this because my flashes worked).

3. Reboot, boot into TWRP. Then I sideloaded lineage-14.1-20181225-nightly & gapps. I got an "adb: failed to read command: No error" @47%(lineage) & 55%(gapps) on the host side on both flashes, that's fine.
Before you reboot, do a factory reset followed by advance > wipe data; (to remove any passwords even if there is none).
Reboot into Lineage, gratz, you now have TWRP & Lineage 14.1 installed.

Lesson learnt:
a.) OTA to b14 before flashing axon_mini_unlock.zip or twrp
b.) fastboot flash recovery TWRP does not work on b12, only b14

Hopefully this saves you the 8 hours of headache that it caused me. I originally thought my device was on b14 but apparently not.

Sadly, no. I never got it working. Being I did not find enough information at the time. That phone was returned as it was unusable for me.

Hi,
I use tuliptool to write recovery tulip-twrp-7.1-r1.img , it say success no error.

@dora123 First you have to update your phone to stock Android Version 7.1 using an update package which you have to download and update manually yourself - read the thread !!!!!

Then it will work
