Bootloop after install GSI (A750G) - Samsung Galaxy A7 (2018) Guides, News, & Discussio

Hello everyone.
I have decided to install a GSI on my Samsung A7 (2018) SM-A750G cos' with the stock firmware the power button does not work (but when installing a GSI the button works fine, and I have no idea why this happens XD).
The point is that I previously had a GSI installed but due to an error I bricked my phone, which led me to reinstall the stock firmware (https://www.sammobile.com/samsung/galaxy-a7-2018/firmware/#SM -A750G) using Odin, and later a GSI using TWRP. But now when I install the GSI my device remains in bootloop. It should be noted that the stock firmware does boot correctly, but the problem is exactly when installing the GSI (with the no-verity and RMM Bypass patches used).
The guides I tried are these:

Hi, try install GSI from FOX Recovery, then swithch back to TWRP.
The TWRP is older, so it dont support Android 10. I had similar problems with bootloader on bit 4 for android 10.

You can find it on 4 pda, and also I saw it here somewhere.

Have the same issue. Can't make it work, even when flashing with orange fox.

android oreo 8.1 firmware leak for alldocube power m3

android oreo 8.1 firmware leak for alldocube power m3 ,guys who own the pad have a try!and give a bug reply post.
alldocube power me oreo 8.1 firmware(0621)
a offical oreo 8.1 firmware with google play for power m3:http://www.mediafire.com/file/qev79...2B32.Neutral.8.1.V01.01.20190118user.zip/file
The firmware is working. One problem: after installation in TWRP package OpenGapps the system crashes. I couldn't find the replacement option (arm64, 8.1). Energy saving is good. Root access - Magisk.
P.S.: Build OpenGapps UNOFFICIAL is suitable for installation and works after components are updated (for example, with Yalp Store or Aurora App Store, F-Droid & etc.)
P.P.S.: If someone decides to install the firmware - must first make a backup of the NVRAM!!! Because the firmware will have to be installed with formatting and the nvram section will die. After flashing the firmware, it must be restored from the saved backup.
For me I got Problems with the display.. Its kinda over saturated.
If someone can explain the rights step to flash this rom would be nice. I cant install twrp over the Flash tool i used this for flashing twrp:

Take my version TWRP specifically for Oreo (the same in Russian how to install and patched Magisk boot.img to obtain root-rights): hire.
The saturation of the screen is comfortable for me, Occasionally settings of installed programs fly off.

Theoretically, should be suitable all the firmware from this theme and some of this. But we need TWRP support Treble, if I understand correctly (I tried the project on another device, everything was already done).
Treble works. As an experiment, I launched Omni 8.1. Started, but gives error 'com.android.phone has stopped'. The system image installed through fastboot (my TWRP isn't able to install to the system partition). The bootloader must be unlocked.
AOSiP Pizza Alpha [EXPERIMENTAL] - wi-fi, sound work, phone don't.
[9.0.0] ArrowOS (Android 9) - very quite good, but again the phone module. Need a system.img way to rebuild, or looking for a fix. In the firmware theme this is the main question. And in general, I liked the firmware, fast response and fast touch interface.

I already have this version installed. The work of the Treble Project checked on it. Firmware international, Google applications available, fixed some bugs. The installation also requires restoring the nvram partition.
Here's an updated TWRP 3.2.1-0 x64 for Oreo with support for the Treble Project (my port from Infinix X571): AFH

Firmware brings up DualWifi again - 5GHz stopped working in former version.
EngineerMode.apk seems to be removed from priv-app's in this release - restoring manually from old image did not help - app crashes.
No easy way to set IMEI on device without MTK EngineeringMode.

mtk sn write tool did the job. - shows up with correct IMEI and VoLTE 4G.

Hello guys. Any update about Lenovo S5?
I am still using Havoc OS 2.9.
This is the only ROM that I was able to boot so far.
OOS GSI did not boot, and AOSP GSI has many bugs.
So far Havoc is almost bugless, together with the pico version of GApps.
Everything is working, from the camera to the lockscreen fingerprint, to the 4G connection and all.
Hi. I accidentally wipe the persist partition while install gsi. Can some share backup persist.img with me. I can't use any sensor at all

You should install the arm64 A-only version because our phone only supports A partition
A64 or Arm64 is about the bitness of the processor. Our chipset is arm 64 bit.
A/B means that the phone has two partitions to support updating the OS or flashing other os without deleteng previous os so that when new os fails, you can revert back without flashing again.

Thanx for the reply, so it means our phone can be brick in wrong flashing because it doesn't have two partitions. The arm 64 Aonly then i have to choose to flash to our device.

Yes. It works for me, but you have to take it at your own risk.
Anyway. This rom is bugless, but the latest google camera doesn't work.

[PATCH] Post-install patch for GSI ROMs 2.0.0

Hello XDA, this patch is intended to fix issues that arise from using phh-based Treble GSIs. This patch aims to make
life bearable on these ROMs and to add the functions that are missing from EMUI 8 and the OpenKirin ROMs. With
this patch you can use any working Pie or 10 GSI and have a complete experience, having to do as few manual tweaks as
possible.
What this patch does:
- Restores offline charging functionality
- Fixes crash on Bluetooth/NFC section in settings
- Fixes headphone jack detection
- Fixes the missing apps in Play Store
- Fixes battery stats behavior by supplying a correct power profile
- Fixes the lack of Night Light in AOSP-based ROMs
Tested P GSI ROMs:
- AOSP 9
- LineageOS 16.0 (AndyYan)
Tested Q GSI ROMs:
- AOSP 10
- LineageOS 17.1 (AndyYan)
Tested R GSI ROMs:
none
Installation:
1 - Flash eva_amend_x.y.z.zip on TWRP
2 - Wipe cache
3 - Reboot
Download:
here
Source:
You can analyze the patch to see the source code.
Credits:
lo_ol, hi6250 community, Wattsensi
Changelog
Code:
2.0.0
- Removed redundant fixes
- NFC is now responsibility of the GSI. This NFC fix was wrong on so many levels I can't even begin to describe.
- All prior versions removed from Google Drive
1.1.0
- Add HWComposer fixes
1.0.0
- Initial release
This looks really promissing - thanks a lot! How about fixing the issue with wifi hotspot for P9? Would that be doable as well?
@Wattsensi Hi. I'm the new owner of an old P9 (EVA-L09) and I would like to install an Android 10 GSI ROM. The only problem is it feels much more complicated than on my other phone. On my (much newer) Nubia RM3, I unlocked the bootloader, flashed recovery, flashed the GSI and tadaaa.
On the P9, I managed to unlock the BL, flashed TWRP and I'm contemplating what GSI should I flash. The treble checker app said the phone is not Treble compatible. It also shows as A-only ARM64.
Can you please guide me on what to install or point me towards a guide?
Thank you

Basically you shall first rebrand and upgrade to Oreo to get treble support, here is how:

@xaweryp Thanks a lot for the input, now I'm downloading the files necessary to rebrand and update to Oreo.

Can I just flash an A only Arm64 GSI, or are there another steps? I have that new recovery (Pretorianos80 v4), but I think it cannot access the internal storage...

Hello. This device is abandoned, we're pretty much 1 or 2 developers working here. Yeah, I agree about the phone being complicated. It has so many quirks compared to my Galaxy S7 where everything just works out of the box.
This phone is not newcomer friendly, but with effort you can get through.
You can indeed install an Android 10 GSI but it's a poor user experience. Your choices are limited with this device, right now we have no working camera or NFC on 10. If you don't care running an older version of Android but still secure you can try @MSe1969's LineageOS 16.0 builds which incorporate the latest security patches and are updated monthly.
That ROM is designed to be used without GApps so keep that in mind.

First of all, do you have your unlock code in hand? You will need it when you perform the needed rebranding procedure. This will reflash your phone with a Chinese ROM so you can OTA-update to Oreo, which introduces Treble functionality into the device. Rebrand, update to Oreo and flash the latest (as of 09/2020) 8.0.0.550 firmware. Then flash the needed network patches to make your radio work, and then decrypt and install TWRP.
First, go there:
https://forum.xda-developers.com/p9/development/rebrand-update-tool-hwota7-p9-eva-t3820849
The second post contains upgrade instructions and be careful. Cheers!
Updated the patch. Now NFC functionality is responsibility of the GSI and removed useless stuff.

How do you install TWRP forever even after flashing OTA and magiks? On Andorid 10?

I already know how to install the unofficail TWRP firmware for my Pixel 4a but it goes back to the custom roms recovery or stock recovery almost every time even after installing ramdisk. What's going on?
Since you are on Android 10, I don't think there will be anymore OTA updates because I think they are only for android 11 at the moment.
To get TWRP to "stick", you probably need to install a custom kernel that has ramdisk built into it as shown in this guide:

Hello, I'm posting this guide for those (like me) who can't do without TWRP on their device. I'm providing only a step-by-step explanation. Credits to @nikamura for his kernel and TWRP...
