Sorry a little bit out of topic, is anyone know the most safest way to extend the system partition for A530F ?? ( firmware upgrade/ odin/twrp/ or should we manually extend partition table using adb)

most of the issue is on newer Android versions, the system occupies more of the system partition and with GAPPS upgrades, larger GAPPS packages (such as stock and mini) cannot fit on the system partition

hey man, I already try all GSI rom that based on Android 11. but, there's no one GSI rom that NFC works. anyone can tell me why? of course on Android 10, NFC works
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] shalannn:
Does this ROM work on Galaxy A8 2018, Exynos 7885 processor?

Does the ROM have any problems or is there an updated ROM?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] KeenShayan:
Gsi's are fairly stable, however I had an issue where my phone would boot up and go back to the boot logo and get stuck there, so I decided revert to the stock rom.

Can i get some screenshot from this rom?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] Daan31:
I've used this Vendor Quack 2.6 on my A530F in combination with Lineage 12 which works just perfectly. The only thing is that I would like to secure my phone a bit more before really starting to us it as my main phone.

Has anybody been able to turn on SELinux in the kernel? I've found a patch but it ain't working :-( My old S5 SM-G900F is running on lineage 18.1 with SELinux turned on.v I would like to have it enabled on my A8 and tried different options like different A8 Vendor options, patches and Magisk but I'm unable to enable it.

Does anyone have some suggestions to enable it or improve security on the phone?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] Daan31:
No you can't; this is a vendor part not a system rom. You need to choose and install a GSI on top of the vendor quack. GSI's can be found here: https://github.com/phhusson/treble_experimentations/wiki/Generic-System-Image-(GSI)-list

Good luck!
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] Kaczka.:
that is, I understand that after installing Pixel Experience 12 (or something else from the GSI list), it additionally installs Vendor Quack so that everything works properly

(and sorry for my english)
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] Daan31:
No you first treblize your phone, install Vendor quack and lastly install the GSI. Pls refer to the main message of this thread where @prashantp01 explained it quite clearly.
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] Kaczka.:
so I understand that after installing Vendor Quack and then GSI, the device will become more stable than without Vendor Quack.
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] Daan31:
If you have a A530F/A530W/A730F your device becomes usable not more stable; without the vendor you can't boot as the vendor contains the hardware specific software and kernel which is your base. On top of the base you can install a GSI; without a proper base you can't use and start a GSI. You should have a look at the picture and documentation mentioned here which quite easily explains: https://xdaforums.com/t/guide-trebl...-guide-for-galaxy-a8-2018-18-04-2019.3894881/

Thanks
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] W33ddo:
Hello,

first of all thank you prashantp01 for your good work!

I would like to ask if Vendor-Quack officially support Android 12 GSIs and if anyone who successfully tried 12/12L GSIs found any problem, especially with fingerprints and/or bootloop after first power off.

Just wondering if it's me making mistakes or it's a Vendor partition known problem.

Thank you all!
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] Catscratch:
Did you make any progress? Do you have a running 12 GSI on top of vendor quack?

I'm especially interested to hear if fingerprint and nfc (Google pay) is working?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] Daan31:
Are you running the kernel still permisive or did you made it more secure? If so how did you do that? It seems the kernel isn't configurable for setting it to enforced mode correct?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] W33ddo:
@Catscratch I'm now using this device with Vendor Quack 2.6 and Caos GSI (Android 11), fingerprint is working perfectly, did not try NFC. I'm satisfied with this GSI.

@Daan31 I did not edit any "pro" setting, just flashed Caos and it worked like a charm.
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] Daan31:
Yes it works like a charm but by default SELINUX runs permissive in a unsecure mode.
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] Catscratch:
Could you try nfc? Much appreciated!
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] W33ddo:
I tried NFC with NFC Tools by wakdev and it sucessfully read a NFC tag
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] Catscratch:
Thanks m8.
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] Daan31:
I've tested NFC on Android 12 (Corvus) and just now on Android 11 (CAOS V316). Both worked just out of the box without any tools. Only with CAOS I needed to enable NFC first (in bluetooth menu).

@Catscratch how did you exactly enabled SElinux enforced mode? If I install Vendor Quack 2.6 and CAOS v316 the kernel is set to permissive state out of the box. When I've installed Magisk and HKTools in order to change the kernel the SELINUX state I get the message:
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] Catscratch:
Sorry m8.

I'm not using any alternativ kernel or rom yet. I'm still on stock.
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] W33ddo:
Wow that sounds like exciting news for me and @Catscratch, did you manage to install Corvus Android 12 GSI ontop of VendorQuack 2.6 without any problem?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] Daan31:
Yes, didn't had any issues except that VendorQuack 2.6 doesn't support SELINUX enforced. Oxygenkernel (https://xdaforums.com/t/kernel-oneui-gsi-oxygen-kernel-v1-0-for-galaxy-a8.3944239/) does support it but isn't available anymore. Also the developer doesn't have the files anymore. The Quantum kernel (https://xdaforums.com/t/kernel-oneu...antum-kernel-v4-0-updated-03-08-2019.3920972/) should support it according to some people but with Android 11/12 it won't boot (at least I haven't been able to).
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] W33ddo:
Does it support OTA updates?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] AlphaMaster08:
Bro Thanks for keeping A8+ alive . Android 11 GSIs works like a charm with just some unnoticeable things .

But Android 12 GSIs have just one common problem , if you try to set a password or fingerprint , it crashes and if you restart after that your phone will go into bootloop (Same Issue on PixelExperience (12&13) and Lineage Os 18.1

Can you please update it so it can support Android 12 or new versions .

Did you find any solution to flash an android 12/13 GSI?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] KeenShayan:
Hey all, I'm trying to fix up the a8 for roms, kernels, all that, however I currently do not have access to my a8 as it will still be stock and daily driven for a few weeks, however I have used it before and am confident enough to write for the device, I just currently am not able to test it directly on the device. I'm currently working on a kernel that can support SELINUX enforced, and make it compatible with a12/13. I have made version 3.7.0-9-0 of twrp with the vendor partition and have attached it to this message, so that's that so far. Long live the a8!
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] rybarillos:
Is it possible, and when you're free, that you may do something like this for the A730F too (the bigger variant of A8 2018)?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] Catscratch:
Is the kernel integrated into the vendor partition? Or how is the procedure of flashing? First your twrp and another kernel on top? Or any GSI directly afterwards?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] KeenShayan:
If that’s the a8 plus, it would definitely be possible and it would need a little bit of tweaking, if any at all.

I’m currently very busy with school but I’ll be using the tree ui kernel as a base, so it’s likely to be vendor image, but it may need a custom boot.img or the likes.

[Android Head-Units] ExtremeMOD:
Very good information here. I've been reading a lot on these forums and it is safe to say that majority of people accidentally bricked their devices without having a backup but also Windows not installing MediaTek drivers properly.
[Android Head-Units] threadreaper:
I'm a Linux user, so I'm not really a good person to ask about the Windows drivers... the best solution I can offer is, "Throw it out, install Linux," lol. Unfortunately a lot of useful and arguably required utilities for working with these units are Windows-only, so I'm working on developing a suite of cross-platform applications to replace them.
[Android Head-Units] ExtremeMOD:
So I dismantled my bricked 8227L unit (accidentally formatted the Flash ROM with SP FLash Tools, but reckon the factory preloader is still there?) and before soldering the test points I wanted to ask couple of n00b questions:

1. When my unit is completely shut down (power disconnected), I insert the 4-pin USB cable and then connect it with my Win10 laptop through USB 2.0 but nothing happens. Nothing pops up, no new hardware detected. I have the latest MediaTek drivers installed. I also tried to insert a USB stick to the head unit just to see if there is any power or reading going on when the unit is on, and there is absolutely nothing. Can this mean my USB on the head unit is faulty?

2. Tried to look at pictures and look online how you actually "short" the test points. Some suggest just to put some solder on the golden plates, you say to connect one wire - but what do you do with the wire when connecting laptop to head unit through USB? Is that wire supposed to touch any other "golden plates"?

Thanks
[Android Head-Units] amit_coolcampus:
I am so delighted to see someone hitting on the hot iron. Looking forward to the detailed tutorial to take backup, unlock bootloader, customize my radio.

I do have the scatter file to flash twrp but as I mentioned on other post that my radio is not detected in Sp flash tools when its off.

When I reboot it, it then gets detected for 2 seconds. I remember I did not remove the power cable may be this is why it's not fully powered off?

I'll try to remove the cable and check if it's get detected.

And then I will firstly start with the backup to stock rom just to be on safe side.

Just a noob question. Is stock backup possible before unlocking the bootloader?

Hi,

I think I have bricked my alps FF-5000 8227L device :(

I did the following steps before this happened:

1. I flashed the HU with this firmware: 8227L_8_UI04-国外11_v1_20210421 UPDATE.zip link

2. The process was successful, everything worked fine, but the screen resolution was much bigger than the device native resolution.

3. I found a possible solution in another forum, according to that I uploaded the attaced files in the zip to the system.

4. This process was also successful but after that the system didn't boot anymore. I can see only black screen with backlit.

I'm not sure what and why happened but I would like to know if there is any solution to fix this or the only one possible way is the test point method recovery.

And yeah, I don't have any dump from the rom. No backups.

Also attached a screen from the stock fw version.

Hi,

I've recently got the HTC Diamond as an upgrade and I'm loving the phone. However I've noticed that regularly I'm having problems making and recieving calls.

The phone dials out as normal but I don't get any sound of the rings, and then once the call is connected I can't hear the other person. This also happens when recieving calls.

The only way I've found to resolve is to put the phone on loud speaker

The phone is only 6 days old and already issues :mad: spoke to someone @ t-mobile who said that they will send out a replacement on monday, I did request if they can send it tmrw as I work during the week, dude said "we don't deliver on saturday" then I said "do you mind checking when I got this phone delivered" yeap saturday!

He said ok i'll have it out for you first thing saturday, I took is name and and team #. Then I called back 2hr later and spoke to someone else and asked when my phone will be delivered, I was then told "MONDAY"!

The guy I spoke to ealier did not even made any note on the account, team # didn't exist....but hey what the hell.

I guess I have to return my handset with everything that it can with included:rolleyes:

Has anyone else had this problem, or know how to fix it, the sound thing that is ?:D
