No longer installed, as the phone rmm locked itself and i had to flash the stock rom and recovery. I don’t know how to un-RMM it as i don’t know if odin can flash the firmware to bypass this lock. I may have not understood all the information you gave me unfortunately…
i had understood that you have the intention to just Flash TWRP, then nothing more for the moment, keeping the stockOS as it was awaiting to find a degogoled custom OS …
Probably worth at least to keep it online with preferably SIM and Wi-Fi in the meantime.
Do you know the phone’s history … possible grey import … region lock ??
it is a relatively old stock firmware,
i think desactivate “system auto update” in the developper options, desactivate “autmatic time settings from the network” in clock settings, changing the date to a month older, then connect to the internet and ask for system update manually should work !
That’s what was planned. U’fortunately, after i flashed twrp, the phone was stuck in a boot loop. So i decided to reflash it…
Thanks for your answer @aibd @piero , i’ll try this tomorrow.
Today i went in the developpers settings to do what you told me and i saw oem unlock shown. I booted to download mode and KG state is checking… Looks like the lock has been reset somehow. I’m now going to follow your guide @piero. Firstly i’ll flasj the recovery that worked for me, and then i’ll get into it. I think i’m gonna flash the A14 GSI as the A13 one has not been released yet. If i ever wish to change from this unofficial to a future official, will i have to do eveeything again ? Or just wiping date and flash the new GSI ?
Many thanks
I tried to flash the new recovery 2.3.7 but twrp told me that the size of the image is larger than targeted device. Do I remain on the one I have right one ?
Edit : do not tell me I can’t mount vendor on this old twrp…
Well, I’m now stuck on twrp as I don’t see the mount vendor only and I can’t delete the “overlay” file. Do you know something that could help me ? @piero @aibd
What is the stock OS version currently installed on the phone ?
Also what is the current installed recovery ?
. Samsung Galaxy A8 (Exynos) · phhusson/treble_experimentations Wiki · GitHub
This firmware is installed:
A530FXXULCUK6
I remember it to be a OneUI version 1.0 and android 9.
The current recovery is twrp 3.3.1-0

Thanks !

Many thanks for your patience and for your help.
Unfortunately, I’ve followed the steps, ( [GUIDE][TREBLE][A530F/A530W] Project Treble Guide for Galaxy A8 2018 (18/04/2019)) but TWRP won’t let me mount System, nor Vendor, nor cache. Only Data. What should I do ?
Thanks in advance !
do you use the TWRP 3.3.0 version as indicated in the guide ?
you should be abble to update it after the repartitionning !
Yes, I flashed it as explained just after treble. I’m running it now. But the partition I want to mount won’t tick ! Just a vibration
doesn’t it already mounted as a folder in /system on old devices (non dynamic partions) ?
Do I skip that step then ??
Edit: I can follow the next step, dalvik cache system, cache, etc can be ticked in the wipe menu.
However, what is vendor dumpster.zip the guide tell me to select here ? And what does “select” means ? install ?

- Make Sure You Treble Your Bevice By This Guide here
- Boot into Twrp recovery
- Wipe System, Data, Dalvik and Vendor.
- Select Vendor_Dumpster.zip
(There’s a link for downloading that file far below, but the link no longer work…)
select means choose between several in the intention to flash one of them.
.
the Original Post has not been updated since years did you read the entire thread ?
you are surely not the first in your case !
pay attention in particular to the response from the Original Poster @prashantp01
you could find another link…
another file that do the job
i you see a guy who is still active, ask him…
you could find information that you can use the later android 10 Q based vendor
see also the other thread about android 10 Q based vendor, if you meet the requirements
search other discussions about treble and you phone model…
good luck…
So if I sum up :
- Trebelize your phone using the steps in that forum
- Wipe System, Data, Dalvik and Vendor
- Flash vendor dumpster found here by the way this repo contains all the fix ever created for A8
- Download the desired GSI (it MUST be A-only_arm64 Variant)
- unpack it if it wasn’t in .IMG format
- Go to TWRP , Install , Install IMAGE
- Pick your GSI and select SYSTEM IMAGE
- Reboot to TWRP Recovery (or system if you don’t want to install gapps)
So according to this post, my question is IS /e/ GSI COMPATIBLE WITH A-only ARM64 ???
Please correct me if I’m wrong somwhere. Besides, the post doesn’t tell me to flash the permisiver ??
EDIT : TWRP FAILS TO MOUNT THE PARTITION, RED ERRORS IN THE LOGS. Any help ??
@manoj Can you please change title to something like
“trying to install GSI on a Samsung A8 (2018)”
@VinK3645
my advise is to back to stock samsung firmare
restarting for scratch
then follow the procedure you found
in this right order
