Also Confused

There are 2 Bootstacks listed

ZTE_A7LOSv1_UniversalBootStack.zip and

A2017x_LineageOS15.1_UniversalBootstack_v1_by_DrakenFX.zip

Will either work, or is there a specific one to choose depending on current OS?

I am currently on LOS 14.1 on my A2017U

TIA

Disabling the lock screen allows the phone to wake up faster.

If I enable fingerprint with pattern the screen stays black for ~10s...and sometimes wakes up

Does anyone know what it could be?

I have lineage is 15.1 build from October + Oki bootstack + gapps + magisk 17.2 + the m1 a1 navigation fix to show navigation keys. It s a fresh install coming from stock...

I have the same question like merck01
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] rx149:
So after a few screw ups (I did the steps in the OP wrong and flashed TWRP before the bootloader and modem and that made my phone not able to get into recovery, reflashing recovery through fastboot fixed it) that I managed to get myself out of I am now on LOS 15.1 from 14.1 on my Axon 7 (A2017U). However there are a few issues that I am having that are probably related to the screwups I made earlier.

Firstly, when the phone is turned on I get the first "your bootloader is unlocked" screen with the orange link that I was used to seeing before but I am also getting a "your device is corrupted" screen after that one. I am able to continue into LOS (after a screen with Tux in the middle) but having not seen this screen before makes me a little nervous about if I installed everything correctly.

Secondly, and more importantly, my battery seems to only max out at 50%. Attempting to charge it does not push it over 50%. I attempted to recalibrate the battery with the battery recalibrating app on F-Droid (with root enabled) but that didn't clear the issue. I tried reinstalling LOS 15.1 after wiping system, data, and cache but the issue persists. I'm suspecting this all has something to do with the bootloader I installed (which I installed from the OP link) but installing it didn't throw any errors for me.

Has anybody else run into either of these issues? I would appreciate some advice.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] EBeatFLA:
Please read the first few posts after the OP in this thread regarding the penguin.

Others in this thread have complained about the 50% battery bug. Try the thread search function out, it's getting lonely, no one ever uses it anymore.

They both work. I believe a minor edit was made, hence the one uploaded in Sept.

I already attempted to use the search to find my issues. The only thing relevant to the battery issue I found was this post and that didn't yield anything useful in terms of a solution. And I wasn't sure if that "dm-verify" solution was relevant to my issue, but now I know it is and it did seemingly solve it. The battery issue is still what I'm worried about the most.

I'm following [MENTION=319057]Oki[/MENTION] guide from here https://xdaforums.com/showpost.php?p=77731728&postcount=1238

At step 9, at the TWRP restart, screen go to a different animation with a small blue curve with circle going counter clockwise. It's been stuck there for 5 minutes now. What do I do next?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Oki:
Reboot. That happens sometimes with many ROMs.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] janthe6th:
I figured out what I did wrong. I need to keep holding the volup button until I enter twrp again.

Anyway, at step 11, I tap on Expand OS and nothing happens. Then I tried to boot to system. At the very first google set up screen I got the google.media has stop and then google services framework keep stopping keep persisting and I cant proceed with the set up.

Then boot into twrp I installed 8.1 gapps micro and tried to boot to system but same thing happen with google services framework keeps stopping.

Please advise.

Edit: keeping everything else from Oki, I tried installing just the latest Los 15.1 rom and gapps and same errors

edit2: I follow all installation steps from OP and still got the google.process.media and google services framework errors at initial set up. can't proceed.

I also tried installing just the rom without gapps but same error

Also tried ext4 and no luck

[MENTION=319057]Oki[/MENTION] do you know if formatting data or cache as f2fs can cause huge slowness on unlock (pattern pin or fingerprint)

If I remove all the security options for unlock, screen unlocks very fast...
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] captainhase:
Just do the Oki installation process again and install gapps before booting into the rom. Had a similar problem and that fixed it for me.

I have the same exact issue. Works on Stock.. Just sucks cuz I'm a huge fan on lineageos but wifi calling is a deal breaker since my work area just has horrible service.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] tprfd:
I used oki's easy install method step by step after seeing a few people having trouble with other paths. I used mindthegapps for Google services instead of opengapps. I had force closes on Google services and trouble with play store until I did a factory reset from within lineage. Once I did the factory reset everything is perfect. There are no issues with gapps, the ROM works really well, the boot up is fast, unlocking is fast, no issues with battery percentage, no issues with airplane mode, no troubles really.

The only thing that is of concern is that I encrypted and the twrp version I have can no longer see my storage so I am not sure how I will be able to update (all my fault for not reading first). I think I can flash another version of TWRP to get around this anyway.

Thank you so much devs.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] janthe6th:
Yes I tried doing the Oki process again and used arm64 mindthegapps but still same problem. I have the U model so when I browse I only need to point it to the main folder right?

it is strange but it bootloader screen my version is ailsa_II - same like in this screen

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] captainhase:
Use Oki's guide from this thread. Did it with my A2017G stock. You have to install gapps before booting into the rom. After that you can dirty flash the newer builds in twrp.

Did you install rom from internal memory or external sd? I do not know is gapps realy matters here, becouse I cant even install rom (error 7) :-/
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] runninghamster:
You need a vendor partition for this rom. Download Oki's PARTY tool and choose the options, ( Create Vendor, 512 MB, After, System ) .

After that, flash a twrp capable of seeing vendor partitions. For example, NFound's 3.2.1-8 TREBLE twrp, or Oki's Labs Mod Twrp.

Also you can install rom from anywhere, it doesn't matter. Make sure to mount everything except persist and USB otg before flashing, just in case.

Still no fix?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] jimhark:
The lineage-15.1 Axon7 builds that require vendor partition attempt to create it. It shouldn't be necessary to run Oki's PARTY tool. That said, if the system update is failing to create a vendor partition, using Oki's PARTY tool may be a workaround. If it runs into this problem, the system update writes "Create /vendor partition failed." to the log which can be seen on-screen in TWRP.

As previously reported, I got the "Create /vendor partition failed" message but it went away after I flashed the TWRP from the OP and retried the system update.

Oh, right, thanks for that. I'm actually not 100% correct on LOS 15 because I'm not using it currently. My bad for any wrong information, I was just assuming what would be natural, since I've not gotten a 'Create vendor partition failed message' before.

Just upgraded to the 1008 official release. Seems fine - just one question.

I had noticed before that the signal strength indicator was calibrated so that it showed a weak signal (no bars sometimes), when I was still able to communicate. Now the indicator seems to be calibrated to show a stronger signal - though a 'signal strength meter' app shows the same signal I had before.

But that's not the issue. What I'm wondering about is that the signal indicator seems to bounce around a lot. When I'm sitting in one place in my NYC apartment - with a good signal, the indicator seems to change every few seconds (~ 5 second intervals). It shows everything from a 20% indication up to a 100% indication. Meanwhile that same 'signal strength meter' app shows the meter barely budging. It's almost as if the indicator on the notification bar is showing something other than the current signal (like perhaps cycling through the various cell towers in the vicinity?). My battery life is okay, so I don't think the phone is constantly hunting for a signal - and my reception is comparable to what it was on stock (not great, but not awful). So what's with the indicaor?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] littlenoodles:
Search on settings not working

search settings' seems to only return apps, not items within the various settings pages. For example searching for 'wifi' or 'wifi calling' or 'location' returns nothing. But 'sound' returns the 'apo info' pages for various apps with 'sound' in their names.

Does anyone know where the auto-updater saves the downloaded files? My phone won't install the new update when it reboots to recovery (Using Oki's TWRP Labs). So I tried searching my entire phone to install it manually, but I can't find it.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] tdm:
It's on the data partition, don't know the exact location or filename. If your device is encrypted, the file is decrypted to clear text before booting into recovery, rendering the actual file useless outside of recovery. Look up uncrypt for details.

bootloader. Everything needed is linked in the OP.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] EBeatFLA:
Why the hell are you using the Nougat bootloader now? Two days ago when you said you were using the Universal Bootloader, everyone assumed you meant the one in the OP. Because typically one would try to follow those instructions first.

Not to mention the numerous discussions and repeated questions in this thread regarding said bootstack, because the dev uploaded a second bootstack at that link without mentioning what the changes were. So you'll have two to choose from at the link in the OP, both work, and nobody knows the difference between them. Enjoy.

I still would like to know if there is even a solution to the 50% battery bug, especially since the only reply I got was "hurr search for it" and searching for it turns up nothing. If there isn't a solution I might just go back to 14.1 or even stock.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] sToRm1nG:

14.1 to 15.1. How stable?

I'm planning to switch from 14.1 to 15.1, but I want to know how stable this rom is now that it is official. When I was on 15.1 (idk which build, probably a late July or August build), one of the two major issues for me was that the camera and video recording would have problems. When I would record video, once I stopped the recording the frame would freeze and I'd have to exit the camera app without a saved video. I think it'd only work when I restarted the phone and even then, that wouldn't always fix it. The same problem occured with other camera apps like open camera. The other problem with the camera was specifically with snapchat. When I took a photo with flash on Snapchat, it'd use the flash, but the photo would be captured a second later. Has anyone else ever had these issues on previous builds of 15.1 and are they fixed now? Also, are there any other problems on current 15.1?

Battery percentage 'stuck' at 32?

Has anybody ever seen something like this? My battery drained more or less normally today, and then flatlined at 32%. Attached is a screenshot of the battery history graph.

I'm on the latest 1008 official release. I did install magisk (17.2) today, following instructions posted in this thread to get Dolby working - and it does work. Could Magisk be messing with my battery meter?

Tried rebooting, and it's still stuck at 32%.

Well, it's about an hour later, and it's started going down again. So, did the battery meter just get out ahead of itself - reporting less charge than it really had until it really dropped to 32 and caught up?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] JKSurf:
A few of us have a 50% battery bug on LOS base roms. You are the first 32 I've heard. We know it isn't a hardware issue because the battery gauge is accurate on stock and nfound's roms. I am desperately looking for a fix for this and am considering a bounty. My current workaround is to reboot to nfound's twrp to check battery level. Also the notification light turns from red to green when fully charged.

What does your battery read in twrp?

I'm stuck in the (unlocked) bootloader and can't boot into recovery. It just keeps booting back into the bootloader every time. I've tried re-flashing the latest twrp image through fastboot, but without any success. Any idea's on how to fix this? Can I fix it with fastboot? Or is my only option to try to get into EDL mode by method 3 or 4?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Snaptraks:
I was in the same boat. You will need to boot to EDL mode and flash something (I flashed Oki's LOS 15.1 package). If you are not able to boot to EDL mode through the button combo and your phone shows up in DFU mode, you will indeed need to use the wire on pin 2 of a USB cable method, which worked for me to get to EDL mode.

Thanks for the fast response! I'm able to boot into DFU mode, but I guess that doesn't get me anywhere. A few questions:

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Snaptraks:
I used a normal USB C cable, in which I put a tiny wire on pin 2 (https://www.youtube.com/watch?v=xFeNSj3ngXY&feature=youtu.be) to get it working. It got me to EDL mode on the first try, but it might take more. And yes after flasshing the LOS 15.1 package I have a fully working phone.

I'm having an issue with dual sims (I want to use sim 2 data):

When I reboot, both sims show data enabled, but neither actually work.

If I go into settings and disable/enable data for sim 2, it works as intended, but eventually it will go back to neither sim providing data until data is disabled/enabled.

The quick settings icon only enables/disables data for sim 1, so it is essentially useless.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] littlenoodles:
I followed your procedure (using Magisk 17.2), and it all seems to work. Wondering, though, what happens the next time I want to dirty-flash an LOS update? I take it I'd need to re-flash Magisk from the same zip that's already on my phone. But since you stress that the order of operations matters, would I need to re-flash the Dolby zip too? And would I have to reboot between flashing the LOS and Magisk zips and flashing the Dolby zip? I assume you've been through at least one LOS upgrade since you wrote this, so would you mind commenting on what you needed to do to keep Dolby working. Thanks.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] roisuke:
So far every dirty flash I've done I'd reflash magisk as the last step and after reboot all the modules are still intact. If Dolby's not working then I'd just reflash the modules all over again. Also I've found that flashing in a particular order isn't necessary as long as audio mod library is the final module that's flashed. Hope this helps :svetius:
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Dodgexander:
This is probably related to the reason why you lose network connectivity when toggling airplane mode on a single SIM, a bug I mentioned previously. The ROM also has strange issues when choosing between different network modes in the mobile data section. You can try manually selecting the network types here that may help you according to your provider. eg calling SIM GSM only and data SIM 4g only. Maybe that helps you with switching.

On an unrelated note to the above, I wish this thread was full more of bug reports than people reporting on failed installations or questions about upgrading. It would make it easier for the Devs to read and fix if there weren't countless numbers of these posts.

There's other sections on the forum to ask questions and get help.
