This is driving me nuts but when you and [MENTION=3044858]DrakenFX[/MENTION] refer to or name baseband files can you name and refer to them by their version strings? Eventually ZTE will push out some new baseband and if you're calling them A2017G_modem_n or whatever no one will be able to tell it's newer than the last one they flashed unless we keep track of the dates of when you make the zips.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Unjustified Dev:
We'll do that when a proper firmware is out. For U it could be b15 Modem but there's only one N for U. That's why I have firmware as B15 when there is a way for users to distinguish I'll do so, but I won't call it by modem version. I'll call it by the firmware is came from. You can easily get the version by mounting the vfat image and open verinfo and get the goods from the text file.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] jawz101:
Thanks!

btw, I'm trying to document these versions in another thread here:

I don't know how I'll be able to find all of the old ones. Probably start sifting through old posts in the forum I suppose.:)
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Unjustified Dev:
You'll have to grab them from each zip and mount them and read that file lol. The stock firmware is pretty huge. Also build date should be in the modem as well. Here's the info for U, G, and China

I've just been having people send screenshots of the About screen so I could get the Bxx number, build date and modem version since that's what us users see.

If I want to flash this can I just start with flashing TWRP? I don't need the N modem etc. right?

Also is there any info about Magicdisk with this ROM? I've never used it but other ROMs make it sound really useful I guess? I don't really know what it is lol but thought I'd ask.

Definitely bearable. If you didn't purchase this phone exclusively for the front speakers it is not bad at all.

I bought it for the Hi-Fi DAC :)
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] aPexalpha:
I bought it because my other one got stolen and the O+3 wasn't out yet, lol.

I rarely use the front speakers. Sometimes for a YT video but never for longer periods of listening to music or anything. Idk about other areas but playing music through your phone speakers is considered pretty rude thing to do in public . And at home you've obviously got better speakers anyway.

I noticed with the unofficial and again now with the official. The default gallery app will not update pictures saved from sources that are not the camera after the first boot. It has permission to storage. I have even tried retoggling the permission. Cleared data and cache on the app to, same result. Photos I download from apps or screenshots will not show up in the app. Camera photos will.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Ogre6473:
I gave that a shot and it wouldn't let me select the folder. Instead it scans the folder, sees all of the backup files, but won't let me do anything other than cancel or go back. I noticed the "This folder is not writable" bit. Couldn't get permissions changed through Rom Toolbox. If permissions are the issue, any recommendation on a better app for changing them?

Copy those backup files that TB says it cannot write to from (extSDCard)/TitaniumBackup to (extSdCard)/Android/data/com.keramidas.TitaniumBackup

Let TB rediscover your backups and select this file location.

I think you will find all will be well.

Good luck
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] bullet25:
Tap the Click to change on the document storage. Choose Document Provider (NOT Filesystem) Choose the root of the SD Card. From the TB Menu again tab the backup folder and you will be good.

I've always had that issue with Filesystem, never with DocumentProvider.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] borijess:
You need to select the storage provider. Then select document provider storage.

I'm up and running, LTE works, Wifi connects... I don't have on screen keys tho.. Was a bit weird when i missclicked and couldn't go back when going through the Google initial setup process..

EDIT: and after a reboot I got out of the 'add another email' part that I miss clicked on and when I clicked 'set up later' I was able to exit the setup app and enable my navigation keys in setup!

So far, everything seems to work flawlessly, however, the onscreen keys should be enabled for the models without physical keys.

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] aPexalpha:
You can get throught the setup process because the keyboard has an Enter button and there is usually a Next button in the setup app as well. However, there is no back button.

Also; can't find SuperSU... maybe just have to flash that again though.

edit: oh dear god, how many Google apps do they ship with Stock OpenGapps?!

edit2: SuperSU works now. Better to first boot, then go back to recovery and flash SuperSU. I tried flashing everything at once, went okay except for SuperSU

So people,please help, i think i screwed it...I need urgent use ma phone...

I was in stock MM (2017G Model).I reboot to TWRP (official 3.0.3.1),then go to wipe, advanced wipe and wiped:cashe,dalvik,data and system.

Then flashed an A2017G_Nougat_Bootloader+ModemFix2.zip from DrakenFX, then lineage-14.1-20170213-nightly-axon7-signed.zip and open_gapps-arm64-7.1-pico-20170217.zip and SR2-SuperSU-v2.79-SR2-20170103215521.zip

I choose reboot system, then i short see an message about unlocked bootloader (as always on booting),then black screen, red led blinkt 3 time and phone is shooted out.

Not started,but as power off.If i powered on it again,the same story, i see first screen with the message about BL, then black screen, 3 time LED blinkt red, and power off...

What i doing here wrong?How i can correct it (to use LOS)?

Thank you all in advance!!!

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] jawz101:
Yes to the first part. The reason for the modem flash is for people who aren't already on stock Nougat because it's a low level piece of the stock upgrade. DrakenFX and UD pulled it out of the stock upgrade to make a tinier zip install of it for us not coming from stock Nougat.

Well, you lose one of two audio channels, so that's 50% of the information, and the too high audio levels can blow your speakers overtime. So pretty bad for a phone advertised as an audio beast
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] jawz101:
It's the dang cmsetupwizard. For some reason they have it set up to assume you use Google so the workflow forces you through a Google setup even if you don't install gapps. The back and next buttons and stuff force you through a Google setup. If the setup isn't what you're used to or you want to go without gapps you have to delete the cmsetupwizard apk from TWRP advanced file manager prior to your boot... But I know what you're talking about.

Use the Aroma opengapps package, pico, or you can use a script to debloat.

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] p_shad0w:
Qualcomm will not give that tool out without a signed NDA. The other tool is probably QPST as they work in conjunction.

It sounds like way too much work for very little benefit even if someone DID get access to the tools....I don't blame ZTE for not bothering to do it to be quite honest since it sounds like a pretty involved process

Nope he has the tool. Your forgetting the other portion of the team is from cyanogen inc which signed with qualcomm. They also worked on the first device codenamed chowder before it was named ailsa_ii . What he's missing is a configuration file to base from of course ZTE can't provide it but they can take his input and apply it since it's not his first time bringing up a device.

Found time to update from 20170202 unofficial. Ran TitaniumBackup and copied data from device. Booted to recovery (TWRP 3.0.4-0), did backup and copied from device.

Factory reset.

Flashed 20170213-experimental build. Rebooted to black screen, red led blinked few times and device went off. So I booted to recovery.

Flashed 20170213-nightly build. Rebooted to black screen, red led blinked few times and device went off. So I booted to recovery.

Now I wonder wtf is wrong.

Now my phone boot looks like that:

1. red led ON, ZTE logo

2. unlocked bootloader info

3. black screen, two long flashes of red led, one short and device goes black.

Revert from Lineage OS to Stock N (Unlocked) - A2017U

Hi,

Sorry if posted in wrong forum section but just wanted a quick ans. I'm currently on stock N B15

If I need to revert from LOS to Stock N B15 with unlock, can I simply TWRP (3.0.4) flash A2017UV110B15.zip (OTA update) ? Do I need to fully unroot as well?

I know about B29 rollback mod but just wondering about reverting directly to B15.

Need to maintain Unlock.

I installed Lineage, and then installed GAPPS stock. But when I reboot, I see the nice lineage OS logo while it boots, but once it boots, I get a white error dialogue box that says "systemui has stopped" and "dialer has stopped" and then the screen just turns black.

I had done the following steps:

1. unlocked BL

2. installed twrp (didn't swipe to allow system mod per instructions for twrp)

3. wiped system, cache, data

4. installed lineage and then gapps stock (had tried with mini, but then I don't have a keyboard to type in my pin)

5. aforementioned error.

I tried this about 3 separate times, same issue. I checked the md5 of the lineage os download and it checks out fine.
