[ZTE Axon 7 Questions & Answers] RandomHelplessFool:
Hey there people!

I just registered thus this is my first post here. I read quite a lot in preparation for this fallowing objective of mine and im still really overwhelmed.

Judging from the amount of super useful guides and comments on this forum I figured I could need a little of that xda community power to help me get this done :D.

In the past I had a few encounters with flashing custom roms on the Galaxy S5 and Oneplus One, however I found doing this with the Axon 7 is way more complicated and I dont know where to begin.

My Problem:

Ever since I switched to oreo I had situations where my device just became completely unresponsive and only the volume keys and the standby button worked however the device could't be turned off except via adb using my pc.

I figured there may be a connection to the current kernel or ROM coming with the b03 oreo update on my A2017G.

As I dont want to buy another phone and keep my Axon 7 as long as possible, I figured it would be best to try flashing LOS on it, as I used it myself and flashed it on every of my family members Galaxy S5's.

I ended up choosing this guide https://xdaforums.com/axon-7/development/unofficial-lineageos-15-1-zte-axon-7-t3800214

but realised I got a little overwhelmed by it.

I installed and prepared the Axon 7 EDL tool on my C drive https://xdaforums.com/axon-7/development/axon-7-edl-tool-flash-backup-restore-t3750759

...which mentions I need to install the original Axon 7 drivers. When connecting the phone to my pc I choose the option to install the drivers and an install wizard appeared which i clicked through. With that I figured that part is done, however the EDL tool says inside device Manager my phone should be defined as "Qualcomm HS-USB QDLoader 9008" and "ZTE Handset Diagnostic Interface(DFU), instead it is listed as "ZTE Handset ADB Interface" under Android Device.

That made me suspicious so while being connected via usb to the Pc i ran cmd and checked if fastboot devices would even show me anything which it somehow didn't.

To check for it I used the same commands as shown by LinusTechTips in his Pocofone f1 video https://www.youtube.com/watch?v=BsHtfLh6azw at 04:10.

In the end I stopped the procedure because I did not want to ruin my only phone, being the helpless fool I am.

Do you have any more detailed step by step instructions for me in that regard, or maybe a more detailed guide to another popular ROM?

The first part of it being unlocking the bootloader and installing TWRP is the main thing here. Within TWRP I mostly haven't had any trouble in the past.

As far as I understand with that LOS 15.1 guide, all I have to do within TWRP is flashing the universal bootstack, then the Modem for A2017G, then the ROM and then GAPPS in one setting in that order.

However its kind of confusing that the TWRP step is taking place after doing these steps, as it should be a precondition to do so.

All I'm looking for is at least Oreo and the more stable + customizable the better.

Or maybe you have had a similiar problem with your axon 7 and know where the problem lies here?

Thank you so much for reading,

have a nice day! :)
