I have the A2017U on LOS. Anyone figured out a way to downgrade back to B29? If so, can you guys direct me to it? Thanks :)
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] shia786:
Hi,

You have to download one of the images from ZTE website which is mentioned in the OP i believe,

And then extract the downloaded zip

Get update.zip and flash that through twrp via an external SD card

You should be good to go

It depends where from, if it's from lineageOS then no, if it's from a ROM on marsgmeow then yes

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] tele_jas:
I believe this is the "official ZTE update", not a full flashable zip...If you try to flash it, you'll get an error or a corrupt system. You have to be on "stock" software to upgrade.

I'd just wait until it's officially listed in the OP, or a separate post.

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] metpolds:
Can any of the experts on this thread help me out of the bottomless pit into which I have fallen?

There is no need to bore you with how I got there, suffice it to say that I am trying to get back to basic B20 and have all the files I need for the upgrade through B20 > B27 > B29 > B15. They are sitting on my SD Card waiting for action but in MiFav recovery as soon as I try to install a zip from the card I get this error message:::::: "Sorry, you can't sdcard upgrade".

My question is simple how the hell can I install the zips. :confused: :(

I have tried fastboot flashing TWRP 3.0.4-1 and then tried to install the zips but the upgrade fails.

Should have said at the start I have the A2017U U.S.A. retail device.

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] metpolds:
[MENTION=421262]lafester[/MENTION] ... Thanks for your reply, can't boot into any system screen (although I suppose you might mean the fastboot oem unlock command not the system developer switch). I honestly don't want to ramble on about my bad steps but for your information my bootloader was successfully unlocked by the B20 method and I subsequently upgraded to B27 and B29 and finally N B15. Lot of wasted words there I could have just told you my MiFav Fastboot screen shows the bootloader as "unlocked". I did do a TWRP backup but when I tried to Restore it yesterday it also failed.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Bolandk:
So, I'm on LOS on a A2017U, rooted with TWRP. Rebooted to recovery, wiped Cache - Dalvik - DATA and System. Flashed the new B15 Stock System zip, follwed by SuperSU v2.79, both of which say they complete successfully. When I go to reboot I get a "no OS installed" message and it hangs at the unlocked bootloader screen. I can boot into TWRP still so I tried it all again but had the same result. Any ideas?

Edit/Update:

So, I got back into TWRP and re-flashed the following in order:

- A2017U_Nougat_Bootloader+ModemFix2.zip

- lineage-14.1-20170203-UNOFFICIAL-axon7.zip

- A2017UV1.1.0B15_systemstock_by_DrakenFX.zip

- SuperSU v2.79

I'm now successfully booted into the welcome screen of B15 and I'm hoping TWRP is still intact.

Looks like we shouldn't wipe 'system' if coming from LOS?:confused: I'll update when I'm in and can check root, TWRP etc.

Update #2

Successfully booted in and restored apps. Checked root using f.lux and it's working fine. People aren't joking in saying that the animations are laggy as ****. I just rebooted into TWRP to clear cache and flash the pixel launcher zip.

Cheers

RESOLVED

I've been sweating golf balls here but at last I am back in the world of working Axon 7's. Thanks again [MENTION=421262]lafester[/MENTION] for your suggestion I honestly don't know why the sdcard was not available to download the required zips but I resolved it like this. I'll keep it as short as possible. The only 2 screens I was able to access were MiFav Recovery and Fastboot, so I used fastboot to flash TWRP 3.0.4-1 and tiptoed round that installation very carefully. I wiped and formatted everything I could then used TWRP to install the full B20 download zip. Then I did the "setup" and in "Settings" did developer options and clicked on oem unlock and also went into Storage (chasing that elusive sdcard) and saw that an option was set by default to "Saving Storage Location Setting" -- "Phone", so I changed that to "SD Card". Now I honestly don't know if that had any bearing on my sdcard errors (I don't think it can of done) but anyway it all went well from there. Long story short ... Now I had a working OS, MiFav Recovery and Fastboot. Used MiFav Recovery to flash the zips on my card. Didn't bother with "Unlock Bootloader Zip", my bootloader was already unlocked, flashed B20 to B27, then B27 to B29, finally B29 to B15. So I'm back to where I was before my troubles except I haven't re-installed TWRP or SuperSU yet, I think I'll wait and see what transpires.

@DrakenFX when you post links to Bootstack updates can you include the actual Baseband version in the zip name or something?

- A2017UV1.1.0B15_bootstack_by_DrakenFX.zip tells me B15 is some version of the U versions bootstack but once I'm on a custom ROM I have no idea what Bxx version includes the baseband I am on. If I had the Baseband version string, however, I'd know if I'm not up to date. Also, when you name the actual zip file for A2017U_N_Modem.zip that doesn't reveal the baseband version I'm downloading. We need to know what is the newest one versus what is a previous one and your naming conventions never tell me what zip is newer than the last zip I used and what baseband version it contains which I could verify in my settings/about screen.

Make sense?

I'm trying to start a list here which shows all of the relevant info of a new version because I cannot discern which is the most recent baseband in what Bxx update for which model based on your info. Doesn't this tell you more about what the latest bits and pieces are?

Example:

A2017U

build: A2017UV1.1.0B15

build date: Sat, Jan 28 05:25:52 CST 2017

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] rczrider:
I'm in the same boat as others regarding root: SuperSU seems to install (systemless, according the the output) just fine, but I'm not actually rooted when I boot up. Here is exactly what I did:

1.) flash [MENTION=540283]tenfar[/MENTION]'s TWRP (keep system read only when entering TWRP for the first time)

2.) wipe cache/dalvik/data/system

3.) flash your bootstack

4.) flash your system

5.) flash SuperSU 2.65

6.) reboot

It booted up just fine (though it flashed the ZTE logo once and rebooted itself for some reason), but no root.

Turned it off and booted into recovery (TWRP was still intact) and via terminal disabled system write protection (reboot disemmcwp) and it booted up fine. Turned it off and booted into recovery to discover that stock recovery had been restored. So I flashed TWRP via [MENTION=540283]tenfar[/MENTION]'s method again and then installed the SuperSU zip in TWRP. Tried to reboot the phone, but all it would do is flash the ZTE logo then go black and the red LED would flash once.

I could still boot into TWRP, though, so I started over starting with step 2 above and everything is back to normal (B27, no root). Two things to note that were different this time:

1.) When I installed SuperSU the last time, it specifically said it was installing in system mode (NOT systemless). I assume this is because I disabled system write protection via the terminal in TWRP?

2.) When I reinstalled TWRP (because stock recovery had been restored) and went into it the first time, it didn't ask if I wanted to keep the system read-only (again, because of disemmcwp?).
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] DrakenFX:
1.- believe that's the reason why SuperSU. When. System instead of Systemless , as far as i know SuperSU zip checks for system before deciding if go Systemless or not.

2.- this may not be the case but you had TWRP and TWRP creates a folder/data of settings. In internal storage like any other app out there. (don't quote me there hehe),

I been notice this is when users AREN'T UNLOCK BOOTLOADER and just use Tenfar tool to flash TWRP...

My best bet is if users go for not unlocking bootloader should flash the Modded B27 boot then wipe data and just install SuperSU from play store as per Tenfar guide.

I'll be updating every post with this info. Later today

I have unlock bootloader didn't have any issues whatsoever.

I may try just locking bootloader and proceed with some testing , but been honest best and easy way to go here will Tenfar Modded Boot.img

EDIT : When you boot back to system is there SuperSU install?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] AllAboutAndroids:
Basically being locked and flashing SuperSU. It doesn't boot up. Without SuperSU, it boots and I'm on the B27 update just fine.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] rczrider:
A locked bootloader requires using PHH, which is systemless, correct? So things like AdAway and TiBu won't work?

Do you have to downgrade to B20 in order to unlock the bootloader?

No, SuperSU doesn't show up in the app drawer. Using a root checker app says I'm not rooted.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] DrakenFX:
I really don't know the answer to this , sorry....

No you don't, just need to either dd the fbop.img (unlock) or flash the zip file I'll be uploading later today.

Have you try installing SuperSU from play store reboot? And run root checker after that?

This assuming you already flash SuperSU btw.

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] DrakenFX:
After flashing SuperSU....
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] rczrider:
No dice. Should SuperSU install as systemless? Because it keeps installing in system mode and I've made sure that my system is set to read only.

---------- Post added at 14:45 ---------- Previous post was at 14:19 ----------

There have got to be some residual files / settings sitting around after all the flashing and re-flashing I've been doing because it took a while to get me back to stock (using your files, actually). I had wiped cache/dalvik/data/system and restored a TWRP backup of my system, but it wouldn't boot (ZTE logo pops up, black screen, red LED blinks once). I tried using [MENTION=540283]tenfar[/MENTION]'s tool to flash stock boot and recovery and boot the phone. It wouldn't boot, just hung forever on the ZTE logo, so went into stock recovery and did a factory data reset, then flashed [MENTION=540283]tenfar[/MENTION]'s TWRP and followed your steps using your files (SuperSU flashed in system, by the way, despite the fact that I specifically told TWRP to keep system as read only). That got me back to stock, but still without root.

I tried as you suggested and installed SuperSU from the Play Store, but it says "There is no SU binary installed".
