[ZTE Axon 7 Questions & Answers] Cyrus D.:
No problem. I threw in an edit to my last post to clarify point 2 in case you thought I meant you can flash the EDL package from Fastboot mode, I meant TWRP in general. In case you forgot the command to use in the ADB shell it's "fastboot flash recovery FileName.img" (twrp-3.0.4-1-ailsa_ii.img in my case).

If you already had the "reboot disemmcwp"/"SU reboot disemmcwp" step done you don't need to do it again.

And just some general information for you regarding my experience with Nougat so far:

1 - When I started it I selected Canadian English as my language. This apparently disables ZTE voice functions, or Nougat is missing it in general. It's missing from the menus and when I hold the back key it said "Only English and Spanish supported". Piss poorly done as usual, ZTE, since the pronunciation of Canadian and American English is nearly identical with very few exceptions, might as well have left American English enabled for voice commands. So I went into the menu and selected just "English" as my system language, and now the option to set Canadian English is missing entirely, and voice functions are still missing. Holding the back key just results in nothing now instead of the "Only English and Spanish supported" message. So I'm saying I don't know if ZTE voice functions are still there, someone else can answer this, or I guess you'll find out.

2 - Google's Timely alarm app (and possibly other alarms) still don't work properly and will be off by several minutes, so I'm stuck using the default sucky clock app until I find something else that works.

3 - The default apps are all still the exact same trash. If you really want to use the AKM "32 bit" (truncated to 16 bit output) Hi-Fi DAC and amp you're still stuck with the garbage laggy default music app, which now has some sort of bonus lag/stutter. People claiming that you can use the DAC with something like PowerAmp are sadly mistaken, that sounds so different and lower quality than when using the stock music app and even says it's using the SD 820's 24 bit DAC when set to Hi-Fi output. There's even a ridiculous rumour going around that the Axon 7 doesn't have the SD 820's DAC which is retarded, ZTE can't pick and choose components of SoCs supplied by Qualcomm, they just buy some of their stock of what's already made. It's definitely in there, whether or not it's enabled is another story.

4 - Battery life is worse, this is at least partly because there is no Xposed support for Nougat yet so I can't enable the Greenify module to allow really aggressive dozing and dozing on the go (which I thought Nougat was supposed to support?). It could also be partly due to my battery being rapidly degraded from Daydream mode being a firey hell inferno. It heated my battery up to 48C and over 42C in other cases even with my best efforts to keep it cool by enabling Ultra Power Saving Mode (which Daydream may be overriding) and shoving in aluminium foil to act as a heatsink. All phones from reports so far overheat horribly when using Daydream, especially the Pixel XL. It's not surprising that the Axon 7 rapidly overheats as well considering it literally uses the battery as a heatsink; a heatpipe carries heat from the SoC to the battery. I would have not bought the A7 if I knew this.

Edit: I forgot -

5 - ZTE locker no longer allows browsing all of their past content, only what they allow per day, which so far for me has only been the same crap and never anything new. Too bad, I liked some of their old content, though it was all 1080p and not 1440p. Oh well.
