Thanks for this.

I tried it with Android Q https://xdaforums.com/project-trebl...ment/rom-android-p-developer-preview-t3816659

Was able to boot fine.

But couldn't get calls, wifi or bluetooth to work.

Mobile data worked fine though.

Does anyone know how to get the calls and wifi to work?
[Samsung Galaxy A8+ (2018) ROMs, Kernels, Recoverie] prashantp01:
Those bugs are unfixable, untill official Android Q sources ain't released :)

[MENTION=7487830]prashantp01[/MENTION] Hey, since Android 10 is out, can this vendor be used for an Android 10 GSI with minimal bugs or is there a need for an Android 10 vendor?

Really?what about fingerprint?
[Samsung Galaxy A8+ (2018) ROMs, Kernels, Recoverie] Sindrom:
I don't know what to say... I downloaded android 10 aosp phh v202. I flashed it with vendor 1.1 it booted successfully and I went to settings to enable gesture navigation. System froze in gesture settings.

Then I went to flash gapps it said incompatible android rom . Android version 8.1!

anyway wifi worked? I forgot to test fingerprint but I think it won't work until a android 10 vendor.

PS I downloaded vanilla version.
[Samsung Galaxy A8+ (2018) ROMs, Kernels, Recoverie] hackuletz16:
Flashed AOSP 10.0 v202 (including gapps) with Vendor Dumpster 1.1

Can't make it past the initial setup.

Without gapps I have tested the the following is working:

wifi

bluetooth

mobile data

fingerprint

what doesn't work

camera

calls

i have installed a web browser but i can't make it work. so i don't really know if WiFi and data works. I think there is a problem with the WebView but it is a ROM problem. You can just turn data and wifi on or off.
[Samsung Galaxy A8+ (2018) ROMs, Kernels, Recoverie] Sindrom:

Hey,

I tried flashing the PixelExperience P you recommended on my A8+ and - for the most part - it works fine... until I realised there's no "phone" app. I can't make any phone call. I asked my wife to call my number and she can hear dial tones on her phone, but nothing on my side. it just showed missed call notification afterwards. Does anyone know how to fix this?
[Samsung Galaxy A8+ (2018) ROMs, Kernels, Recoverie] hackuletz16:
V206

What I tested

Mobile data - 3G LTE is working for me, check pic

Camera - see picture, check for signal

Wifi working- see picture, check for signal

Audio working

This is all that I need. For me, it's usable. Will test it as daily driver.
[Samsung Galaxy A8+ (2018) ROMs, Kernels, Recoverie] hackuletz16:
Fingerprint not working. Tested with Vendor Dumpster 1.0 and 1.1, with and without the fix.
[Samsung Galaxy A8+ (2018) ROMs, Kernels, Recoverie] Sindrom:
Hi guys.

I have tested evolution x 3.5 and AOSP Android 10 v208 (gapps included) none of them work. They both froze in first setup.

I wanted to ask has anyone used lineage os 16 or 17 in this phone?
[Samsung Galaxy A8+ (2018) ROMs, Kernels, Recoverie] amrazing33:
Same experience with AOSP Android 10 v208.

As for LineageOS, I tried LineageOS 16 before. It was working, but I think there were some bugs I can't remember what (I think one of them was the fingerprint sensor; I couldn't get it to work even with the patch zip).
[Samsung Galaxy A8+ (2018) ROMs, Kernels, Recoverie] Sindrom:
Thanks for answer.

Maybe I'll try lineage os 17.
[Samsung Galaxy A8+ (2018) ROMs, Kernels, Recoverie] Sindrom:
Lineage os 17 boots.

But no fingerprints (reset after restart)

No mobile data

WiFi working

Camera working

Gesture navigation not working.

I thing we need an Android 10 vendor to have this thing work.

Or at least a port of one UI 2.0 from other Samsung phones.

Does any of the GSIs work with ADB. Also if your go to the Phh-treble Settings, you can find the fingerprint workaround there,

-do not flash the fingerprint flash when installing the GSI, just boot into it, avoid setting any fingerprint

-go to the Phh-treble settings

-click on Samsung settings

-Under workarounds, tick the broken fingerprint option

-Restart the device and set up fingerprint
[Samsung Galaxy A8+ (2018) ROMs, Kernels, Recoverie] Kaduah13:
For the system images that do not work

I have tried installing the Evolution X 4.20, as expected it didn't boot until I installed a selinux patch which was supposed to be for an unofficial CRdroid. I have placed it there but it worked when I did a clean flash with nothing in there.

Anyone else's Google app using way too much battery ?

Sync & location always turned off, so I don't know what else could be using that much battery.
[Samsung Galaxy A70 Questions & Answers] GavCity:
That is an unusually high amount. Google App has used 12.8% over 14 hours on my phone with sync and location on and using assistant and other features throughout the day. Still seems a lot for me but not too worried as the phone is making it easily through the day with a lot of use. Yours does seem problematic though. Give it a reboot, it shouldn't be that bad even with stuff turned on.
[Samsung Galaxy A70 Questions & Answers] Sufyan3D:
Too much battery drain. Clear app data/cache and restart phone. Put the app in optimized mode so it goes to sleep when not in use, or turn on restrict background activity for the app.

Hello, i have ZTE Axon 7 Gold model and i bought silver one which i bricked. I flashed Unlock bootloader for Nougat instead of Marshmallow in ZTE Axon 7 toolkit. I can't boot to EDL mode, when i try to hold all buttons for 5 seconds, it shortly powers off and it shows red dot again. I have only QUSB_BULK when connected in device manager and i can't flash anything with it. Please help.

I can't access EDL, ADB, fastboot and DFU mode. No boot screen, nothing, it just stays black. I will try to discharge it.
[ZTE Axon 7 Questions & Answers] SkaboXD:
Hello guys again, i solved my problem. It was a driver issue. I installed every driver, including the driver raysteff66 provided and it took time while cleaning old drivers. It didn't worked. What worked for me is using driver navigator (you can use similar driver installers). I don't use these program for daily use (they're not recommended for it), but when drivers simply refuses to install, they come to the rescue. It found that i have missing ZTE DFU driver. I downloaded it and program force installed it. After that i rebooted the system and Voila! it detects my device as DFU. After that i used DFU MultiDL tool and it switched it to Qualcomm 9008 EDL mode. I flashed EDL Rom and celebrated my success.

Read this if you have QUSB_BULK as your only driver displayed in device manager.
[Android Q&A, Help & Troubleshooting] specialdo:
Hi everyone!

I'm trying to modding an android app for the first time.

Before, this app worked on Android TV but with the last update, after the splash screen, it closes.

I decompiled the app and I found the points where to intervene to allow the app to start on android tv (skipper technicolor).

UiModeManager uiModeManager = (UiModeManager) getContext().getSystemService("uimode");
if (VERSION.SDK_INT < 8 || uiModeManager.getCurrentModeType() != 4) {
return false;
}
NexLog.m15032d("NexVideoRenderer", "Running on a TV Device");
return true;

But I don't know how to compile and sign the app to be able to try. I tried with android multitool but when I try to decompile the app I have many errors.

Can anyone help me?

thank you so much!
[Android Q&A, Help & Troubleshooting] RealWelder:
I just use regular old apktool, myself, but really in order to help I'd need to see the particular errors being thrown.

Also for signing, Venkat Kamesh has a really nice and easy to use tool for Windows called signapk.

Hi RealWelder, thanks for reply.

I tried with Android multitool (the new version of apk tool) but the errors are on the framework.res.apk. Where I can find it?
