At last I finally have a working build! I have no idea what was causing me so many problems as I never could get an error that pointed at anything being wrong. Thank you for your help and all the info you have shared with me, but after the last make clean && make clobber everything seems smooth. Yall have a good weekend.
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] :
confirmed.

updating from Lineage 14.1 to 15.1

1: format system, cache.

2: install lineage 15.1 and oreo gapps.

and everything works fine I do not see any error.

Cool

I just found these betas for K88. I see that they are almost 2 months old. Are there any newer betas out (or is stable due out soon)?
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] tdm:
I've been very busy. I'll get selinux done when I get a free day. Sorry for the delay.
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] dclou:
Which version of Gapps should I download?

For Android 8.0 or 8.1?

Please guide and thank you for the help :)
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] :
8.1 gapps
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] jd45321:
When you add the selinux will this be out of beta and stable?
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] tdm:
Yes I think so.
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] jd45321:
Great, Thanks. Looking forward to the update.

Any hope of getting call function working on next build?
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] tdm:
Unfortunately, I haven't figured that out yet. I did try a few months ago but never succeeded.
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] dgmustard:
Been running the LineageOS beta (10/17) for a few days now. I did a clean install with stock gApps. I had an issue where no keyboard was installed (only option was voice keyboard) when trying to use mini gApps but that was probably something I did on my end. I originally tried doing an upgrade from LineageOS Nougat but also had the issue of all apps crashing that was mentioned in this thread earlier.

Everything runs very smooth!

I'm not sure if you have a list of issues that aren't in the first post but the only issues I've discovered so far are:

* 64GB SD Card is detected as corrupted (already mentioned in this thread). TWRP (3.2.3) has no issues reading from the card

* LiveDisplay does not work - The setting is always set to disabled when trying to change it
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] :
And ambient display? Right

[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] dgmustard:
Correct. When searching for "Ambient Display" in Settings, there are results but clicking on them doesn't return anything (similar to when searching for hotspot on a phone when your data plan doesn't include hotspot)

tdm had mentioned it's on his list of things to fix in an earlier post so I didn't include it in my list
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] :
hotspot works well for me
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] :

Good day to everyone in here, sorry in advance if I may sound offensive to the developers in here about my question. May I ask about latest progress in regard to Oreo stable build. [MENTION=4126377]tdm[/MENTION], [MENTION=6064227]juniorgerman[/MENTION].

Thank you
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] tdm:
I'll get it done soon. Just too busy with other things at the moment.

Oh and by the way, pie is a very easy jump from oreo. So that should come very quickly after oreo is done.

[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] acdcbeatles1980:
Thanks to you, Trek2 is being used very usefully.

I have a question.

There is a product ZTE primetime K92 which is a successor of a ZTE Trek2.

Do you plan to support LineageOS in ZTE Primetime K92?
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] :
1.donate to [MENTION=4126377]tdm[/MENTION] to buy the zte k92

2 find zte k92 firehouse to create the EDL flashing tool

for k88, something like that was achieved.firehouse for the k88 I found it and it came up asked what it is and the answer is the programmer's firehouse

quickly tdm developed the edl flash tool

later we contributed in donations and tdm got his K88 and the development advanced

but I do not know if he is willing to continue with another device because he is very busy in his life

edit.

I missed something?
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] tdm:
[MENTION=9714050]acdcbeatles1980[/MENTION] i've found the K92 firehose, if you want to test to see if it works I'll be happy to do that in PM. If we can get it working, I'll build Lineage and AOKP for it.
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] kitboot88:
I am a K92 user.

I do not know "firehose", but if you let me know how to test it, I'll try it.

Well this is good news. I've been looking for info on rooting my K92 for a while. I honestly thought it was hopeless at this point, but maybe that's not the case.

Definitely update when there's progress with this. I'd use the tablet a lot more if it was rooted.
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] :
I think I'm going to buy ZTE K92 and sell Trek 2

I'm just saying why the AT&T Primetime chipset MSM8953 is good for ROM development

Although I am 3 years old using Trek 2 and in development it is a bit slow

I borked my K88 (just keeps blinking on/off att / android 1st screen but I can get to TWRP) and need to reload. Thought I'd try this, but says need to update TWRP. But TWRP link (Prerequisite is not working)

Prerequisites

All oreo builds require an updated TWRP to flash:

jasmine-twrp-7.1-3.2.3-r1.img
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] :
the service of [MENTION=4126377]tdm[/MENTION] is broken
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] jd45321:
Is jasmine-twrp-7.1-3.2.3-r1.img needed to install Dotos 2.5 or Resurrection Remix v6.2.1?
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] jd45321:
Also, is new twrp available anywhere else?
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] suhridkhan:
I don't have the latest twrp version.

But I have 'jasmine-twrp-7.1-r3.img' version installed and it works with DotOS, but doesn't work with Resurrection Remix.

Hopefully somebody saved a download of the latest twrp.
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] jd45321:
Looks like tdm's site is back up. Link in 1st post worked for me. Now I need to figure out how to update TWRP.
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] RaVeNV1:
Download the newest TWRP image -> boot into TWRP -> go to "Install" -> choose "Install Image" -> navigate to the place where you downloaded the image -> press it -> check "Recovery" -> swipe.

That's it.

Edit: Btw, I didn't realize that I had an outdated TWRP version. I was still on 3.1.1-0. So thank you for the "reminder"!
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] jd45321:
Just installed this. Can't figure out how to add a new APN (Access Point Name). Can't find the new or add button.
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] ativi:
I never have to worry about configuring APN, as it's automatically done during setup screen, without it I will be locked out, as I always have to go through GOOGLE FRP verification process. But did you do a clean flash? I have never experienced your issue here before, I don't know about others here having same issue.

---------- Post added at 09:03 PM ---------- Previous post was at 09:02 PM ----------

Can you check if your SIM card is detected by the tablet?,
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] jd45321:
Yes it seems to be recognizing it. I use a service on tablet that uses att network but have to enter a different APN to use it. But there is not an add or new button. This was AOKP, I'm going to try some of the other Oreos (Lineage, RR or DOToS) if neither of these have an add, I guess I'm stuck with nougart

[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] ativi:
All are good builds to try or use, it's based on your personal choice or flavour. No harm in trying the two and choosing one which meet your expectation.
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] lihhtrell2x:
Thanks for the help, i didnt know the difference bewtween each name, i thought maybe that aokp and linageos ROMs had different android version requirements or something, but which one did you like best?
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] ativi:
I like the aokp best as it already have have lots of customisation options built in to it, no need for use of xposed and modules such as gravitybox to flavour it.

LineageOs on the other side has little customisation options and you will need add-ons or modules to add flavour to it according to how you want your tab to look and function.

ZTE K92 users no longer have hope for Lineage OS.

Hey, can someone help me with a weird issue i have been having on my K88? the issue i am having is that when i decrypt my K88 wifi doesn't work but other stuff works, and if i encrypt the tablet wifi works but after 2 or 3 reboots it comes up with "to start android enter your password" i never even set a password but it keeps doing this. default_password worked only once but then after that it doesn't work anymore. btw. this only happens on custom roms. but i never seen anyone else but me have this problem.
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] :
Surely you installed mods like xposed that caused him trouble.
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] ItzBluestone:

I had the same problem. I was putting on oreo image, gapps, and magisk su. If you put the magisk on later, another reboot, the wifi config error goes away

Ive been having issues with screen dimming very quickly, regardless of the setting in the rom. 30 seconds or less. Ive played with all the settings i can find, no luck. Anyone else having this problem? I went back to stock briefly to try and set it there. Under stock it didnt happen. On the custom roms it does. Thanks for the nice work on these roms though

Edit: I timed it, the screen fades to black in time varying from 2-3 seconds to 12 seconds. Anyone else?

Edit 2: Ok got it all figured out, its working great. Having google recover the apps also recovered some settings that were causing it to blank out quickly and randomly. Do a clean install, no recovery, I think it says for a fresh look

Here's what I did:

Advanced Wipe everything but MicroSD and USB OTG

Flash Oreo

Flash Gapps

Wipe Cache/Dalvik

Boot system (wifi works)

Go through startup panels.

Do not restore any google backups

Reboot recovery

Flash Magisk

Reboot (btw I never installed the TWRP app from the last page since its an orphaned TWRP, doesnt really do anything)

Presto! An awesome working Oreo build for a great tablet. Nice and fast.

Thanks tdm and all! Trek 2 lives on and without the weird OEM lockscreen. I hated that thing
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] fabiop10:
Installed the Oreo firmware in my tablet this week. It seems to be working fine.
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] virucyde:
Installed the Lineage OS variant today over the Lineage OS 14.1 that I had on there. One of my kid's games wouldn't work without Oreo or above, and I tried the dotOS 2.5 ROM with Oreo, but the game would install, but get stuck on loading screens with that one, and all of the Endless kids games would crash when starting them.

Set up with Nano GApps 8.1.

One thing I noticed that's different from the 14.1 build is this build seems to have fixed the starting asking you for Wifi AFTER asking about transferring from another device, this one did it up front, which is good, I had to say "fresh install", set up Wifi, then go back to transfer data on the other one during startup.

It still seems I'm not allowed to say "No Thanks" to Google Assistant, if I do it just tries again until I agree.

I'm a bit weirded out why the notification sound is using an Alarm by default..

Got everything installed, confirmed the Endless games don't crash, and confirmed that the other game that required 8.1+ was able to download and start games!

Thank you so much, this breathed additional life into this tablet, and I'm sure my 3yo will be very happy to have it working on his device!
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] Wiesshund:
Maybe no one is using these tablets any more but

I successfully installed TWRP

I got magisk installed and i flashed to the official 7.1

Ok all of that worked fine

Using files form here by the way

Index of /android/k88/

Anyways that worked fine except for all the AT&T bloated junk etc.

So i did a full wipe and then loaded

aokp_jasmine_oreo_UNOFFICIAL_2018-10-17.zip

and open_gapps-arm64-8.1-micro-20211112

Reboot, it starts to go through the setup, and then the google apps keep

stopping

Wiped all 3 times, and reinstalled, same result

lineage_jasmine_oreo_UNOFFICIAL_2018-10-17.zip

this one works,sort of, i can at least get set up and to the home screen

then google services keeps stopping

Can run other apps, but nothing google related, they just crash loop

Can reflash back to factory 7.1 and all is good.

Others seem to run the orea versions fine though, so i am wondering, what am i missing?
[ZTE Trek 2 ROMs, Kernels, Recoveries, & Other Deve] thejaredhuang:
Can anyone check if their FM radio works on this ROM? Just flashed and it didn't work, also didn't work on my Nougat ROM. It will open and even detect for headphones but won't play anything or seek to stations.
[Google Pixel 2 XL Guides, News, & Discussion] Danne9900:
Hello!

So... i have looked all over the internet to find what the difference is between these phones and all i can find is that they have the same camera setup at the rear.

But.. the pixel 3 takes marginally better pictures then the pixel 2.

How can it? Is it depending on the software? The camera app?

If it software then it should be able to get? ( Already seen some ports)

The question: whats the difference that we cant get or can get?
[Google Pixel 2 XL Guides, News, & Discussion] SinisterXReaper:
I'd say it's a mixture of both software, and an updated chip inside the 3.
[Google Pixel 2 XL Guides, News, & Discussion] Phazonclash:
I suspect it's software, more than anything else
[Google Pixel 2 XL Guides, News, & Discussion] Danne9900:
Okey,

But what chip makes it possible to take better pictures due to the same optics?

I havent seen any spec of a new chip? Beside the SD 845
[Google Pixel 2 XL Guides, News, & Discussion] reawo:
The Camera Sensor itself received an upgrade - it's not the same as in the pixel 2.
[Google Pixel 2 XL Guides, News, & Discussion] SinisterXReaper:
It's the pixel visual core (PVC) chip. The Pixel 2/XL has this chip as well, however, they made improvements to the chip in the new Pixel 3/XL, along with really focusing on the software aspect of the phone. Sticking with a single rear camera is Google's way of giving other companies the bird saying "we can do better than you with only a single rear camera" IMO.
[Google Pixel 2 XL Guides, News, & Discussion] pemz82:
The headline specs are the same

12.2 MP, f/1.8, 28mm (wide), 1/2.55", 1.4µm, OIS, dual pixel

But it is apparently a different(newer) sensor. That combined with upgraded Pixel Visual Core chip for processing lead to slightly improved images
