GSIs on A60/M40

Proof of concept - I've successfully booted my own LineageOS GSI on A60 (which is identical to M40 in terms of hardware); other PHH-based GSIs should work as well.
Procedure? Just pack your favorite ARM64 AB GSI image into a .tar and flash via Odin. It's that simple (to at least make it boot).
As far as I've discovered, bugs are 1) bad manual brightness behaviour (can be fixed similarly to this - the command to use here is "setprop persist.sys.phh.samsung_backlight 2"), 2) calls are always in speaker mode, 3) MTP is broken (can be fixed with a modified stock kernel in the future) and 4) no VoLTE as with all GSIs.
If you install one now, there's no navbar on boot, and statusbar doesn't account for the hole-punch either, but I've already submitted a device overlay to PHH, which should fit both A60 and M40. GSIs built afterwards should look better (like in the screenshot, where I already applied the overlay).
With no TWRP available, setup can be tough, but overall it's pretty refreshing to see AOSP-based stuff running on this device.

As a m40 user it sounds me great and left hope for my device.. looking foreword to it

dear AndyYan, could you provide links(to twrp and GSI themselves) or something?
sorry. no need of providing. I misunderstood

Great!
Great Work buddy. Hope you make progress and soon have a smooth GSI on your device :good:

Hey, when im trying to flash with odin (AP), the app has just shutted down. What's the correct way to install?
Even tho, app for checking treble says me, that i have A-only while you say youve flashed AB

My bad, I forgot to mention that the image has to be renamed to system.img.ext4 before packaging.
We're A-only but system-as-root. Images for system-as-root are named AB for historical reasons.

Then probably dm-verity kicking in (weird, how come when we've unlocked BL already).
I installed Magisk beforehand (patch AP), try it yourself.

Can you make please more detailed guide how to flash it
Because when I try, it gives me error

So slightly more details:
1) Make sure Magisk is properly installed (patch AP) and running on your device first, likely because we need it to disable dm-verity
2) Download any ARM64 AB GSI and rename the image (*.img) to system.img.ext4
3) Pack it into tar format (e.g. 7-zip)
4) Flash via Odin
5) Enter stock recovery and wipe data
I'm not too keen on showing the way because an official Android 10 update is around the corner (being intensively beta-tested in China), which could potentially fix the bunch of bugs in running GSIs (most critical being call audio).

im noob bro can you give me your facebook or instagram please :<

@deadinside322 I see you're from 4PDA, greetings. The flashing process does not involve TWRP (we don't have one), which is admittedly unorthodox. What error did you encounter anyway?
BTW I've tried a few ways to port TWRP with no success. I wish you luck there, and don't forget to open-source if you do succeed.

Hello, I also tried to port TWRP three times already, it didn’t work out in any way.
The problem was that the firmware in Odin was infinitely loaded, and some simply did not want to boot.

Android 10 has released for both A60 (A6060ZCU1BTC9) and M40. I've switched to using it as base for GSIs, and it fixes the call speaker problem; other mentioned issues remain. The flashing process stays the same as well.

Changing firmware galaxy m40 to galaxy a60 open china
Hi, im using galaxy m40, if i flash the galaxy a60 firmware, my phone work or brick, has any one try that?

have anyone tried flasing android 12 gsi to m40?

Info For U Model Bootloader Unlocking Can Be Found
[Android][UNSAMLOCK] Bootloader Unlock for Samsung US/Canada Devices
This thread is @svetius approved Important notice: Do not update to April 2023 security update (XXXXXXXXXXWCX) or later. Examples: G998USQS6EWCA, N986USQU4HWD1. Samsung has patched the bootloader unlock again on those updates. NOTE: The OneUI...
forum.xda-developers.com
Below US snapdragon devices can be bootloader unlocked with above service as long as bootloader version meets below criteria. Bootloader version can be determined from the 5th character from the right on the baseband version or build number, in some cases from kernel version
Below Method is no longer supported if you choose to use the unstable method below you do so on your own
This method is brought to you entirely by @elliwigy He is the reason for this exploit and method.
With that being said, Extreme Syndicate Root is now available!
Before Starting This Process Get A USB2 Mini Hub You Are Most Likely Going Too Need It​
EXTREME SYNDICATE ROOT METHOD
​OEM Toggle Does Nothing On US Model Phones
This root method breaks things and most likely will not be able to be used as a daily driver
You can be on any version bootloader. This will update you to V9 bootloader
This method will work if you are on Android 10 or Android 9 Pie but will put you on Android 8 Oreo. There is no root for Android 10 or Android 9 Pie
You will not be able to use magisk
You will not be able to flash full custom rom like Lineage or any other AOSP roms however GSI system images can be used
You cannot flash custom boot images or recovery images such as regular TWRP
Odin does not work on some later computers with USB 3.1 chip controllers the only work around is using a USB 2.0 mini hub
It is your responsibility to make sure you can use adb properly
Root will break things such as safetynet so deal with it
Disclaimer:
The Extreme Syndicate team and it's affiliates are not responsible for your actions or your device if any issues are to arise. You flash this and utilize these files at your own risk. You have been warned!
Notes:
- Safestrap recovery is now available with working MTP while in Safestrap
- This does NOT trip KNOX so don't ask.
- Bootloader is of course still locked.
- This uses some partitions from combo firmware which means 80% battery.
- Each variant will have its own post in its own download section. Download the right stuff!
* Variants this should work on are: N960U/U1/W, G965U/U1/W, G960U/U1/W. If you do not have one of these variants then this forum is not for you!
- Initial files/method will leave you on Oreo stock root.
- It works on latest rev's from rev1 up to the most recent revs.
- As of the initial first release, all variants have an issue with MTP not working except while in Safestrap
- S9 and S9+ also might have some issues with the selfie cam.

Anything here with a .7z extension will get unzipped before using
Anything here with a .zip extension will get flashed as a zip in safestrap
Anything here with a .tar or .md5 gets flashed in odin
Anything here with a .img extension gets flashed as image in safestrap
Downloads S9 Files:
Safestrap_S9_Cmd_Line.7z
Download S9+ Files:
Safestrap_S9_Plus_Cmd_Line.7z
Download Note9 Files: -- Only For Bit 8 Or Lower
Safestrap_N9_Cmd_Line_Bit8.7z
Instructions to Inject Safestrap:
1. Download and unzip Safestrap_S9__Cmd_Line.7z for your device
2. Plug phone into computer and run Safestrap.exe
3. Follow instructions on screen to enable USB Debugging
4. Then from there the process will be mostly automatic just follow prompts on screen
5. When done flashing BootSwap file you need to hold the buttons to boot to recovery but since we swapped boot and recovery images it will boot system.
Instructions For Flash Rom:
1. Download below files and copy files for rom to phone system img and vendor img and odm zip
Downloads S9 Files:
Stock_Rom_G960.7z
GSI_Rom_G960.7z
Download S9+ Files:
Stock_Rom_G965.7z
GSI_Rom_G965.7z
2. In safestrap flash system img then vendor img and odm zip .
3. Choose data wipe and advance and check data
4.. Now reboot system you will have to hold buttons to reboot to recovery until you see safestrap splash then click continue. You must do this on every reboot. If you do not it will reboot to stock recovery. If it reboots to stock recovery just reboot system and hold buttons to reboot to recovery again.
5. When rom is booted up your computer will not recognize the phone for mtp file transfer. Adb does still work so you can transfer stuff that way (you need to switch to ptp transfer method in the dropdown) or use USB adapter and use a thumb drive.
6. Biometrics do not work so don’t try to setup fingerprint or face recognition.
The GSI rom mtp works GSI rom is rooted already just flash phhsupersu.apk found in GSI_Rom zip
If using other GSI roms you have too choose A_Only ones and will probably need to flash the Sh_Remover.zip found in the GSI_Rom zip

As of right now it's still detecting su binaries. So Samsung Pay probably may not work.

On my G965/U1 I do not even see a "/system/etc/init/init.lab.rc" file on my device, is this because I am updated to the latest Android 9 December 1st security patch?

Don't worry about it. It will work on it, it's been proven to work exactly on Android 9, Dec 2019 security patch.

Wow! that's exciting, I can't wait until this releases. Looks like I'm not updating my phone anymore until then. Especially exciting if it works on Android 9 December 2019 security patch

the question is how likely this will be patched in Samsung's next update and how much time this may cause them to delay their next security patch.

how to root , flash custom recovery and custom ROM on galaxy S10 5G (G977N)

Hello folks !
I just bought a galaxy S10 5G G977N and I found it difficult to work my way through all the changes made in rooting/custom roming smartphones (I had a galaxy S7 before that, it was pretty easy).
What I read for now :
How to root with magisk : https://topjohnwu.github.io/Magisk/install.html#samsung-system-as-root
How to install TWRP : https://twrp.me/samsung/samsunggalaxys105G.html
What I learned :
Rooting device is far more complicated than it was before. If I do so, I won't be able to update stock rom OTA, I'll have to reflash a patched recovery (AP file) for every update. This bothers me because its not convenient, and because messing with odin is way riskier than flashing zip from custom recovery and may brick my phone, so the less I use it, the better I think.
Plus,booting the phone will be a pain in the ass, having to do the right key combination
Installing TWRP will not change that.
What I'm wondering :
I'm a bit confused on how I will be able to update stock ROM (The way I understand it, I'll have to reinstall TWRP after each update)
And I'm even more confused about how all of this will work with custom ROMs.
Let's say I root my phone and install TWRP. If I want a custom ROM and keep it rooted, how will it work ? I'll have to unzip the ROM, patch the AP file with magisk, rezip it, flash it with twrp and voilà ? And I'll have the same key combination issue where I'll have to boot a certain way to access the rooted ROM, and if I don't, I'll boot on an unrooted ROM ?
Thank you a lot for helping. I'm really used to rooted and unbloated ROM (God I've forgotten how bloated stock ROMs are !) but the complexity of the operation stops me for now. I don't want to brick my phone and I'm not sure I'll have the courage to do all of this every 3 month for each update.

Hello!
This thread is a bit old. But since I had to dig the forum to find what I was looking for (and update my knowledge), maybe my answer will be useful for somebody else.

I agree! Thankfully, somebody smarter than me took care of that. You can thank ianmacd for his multidisabler (GitHub project's page; xda thread).
One of its functionality is to disable "Stock recovery auto-restoration".
If you want to see a guide for how to use it (for S10 5G Snapdragon only, but same principle apply for the others), afaneh92 wrote one! Same thing by corsicanu, but with official links to download TWRP (and his repository for the other stuff), and it works with other versions of the S10 too. corsicanu got his tools here if needed.
Be careful, you must format /data after disabling encryption with multidisabler. Back up your data first!
I won't be able to update stock rom OTA
Click to expand...
Click to collapse
No OTA if you root.
You can still upgrade the stock kernel/firmware to a newer Android version manually. Afterwards, flash TWRP, then flash multidisabler again, then run multidisabler in terminal. And, all good!
(Reflashing stock firmware disables "multidisabler")
Check for firmware updates on Samsung's changelog page.
Replace your S10 model number and CSC code in the link below:
doc.samsungmobile.com/YourModelNumber/YourCscCode/doc.html
To know which CSC you have:
Go to Settings > About phone > Software information > Service provider software version
The last line should show the current CSC (three characters), e.g. mine is KTC for Korean KTC devices.
doc.samsungmobile.com/sm-g977b/ftm/doc.html
corsicanu makes it easier for us, here is his github page for the S10.
I'm a bit confused on how I will be able to update stock ROM (The way I understand it, I'll have to reinstall TWRP after each update)
Click to expand...
Click to collapse
To flash the ROM the first time:
Flash the ROM with TWRP (adb sideload), Format data/factory reset. Formating everything will reenable encryption if you had multidisabler installed first. I think. So I guess flash it afterwards, and format data again?
For example, you can follow Lineage OS's guide. But they don't take care of vbmeta, encryption, and other issues. I'm not sure why.
To update the ROM, it's easier: no need to reinstall multidisabler after a dirty flash. (Lineage guide to update their ROM)
I'm dropping some links you might need:
To download the last version of Odin (odin3-v3-14-1_3b_patched-zip as of date): realbbb's XDA thread.
All the versions of TWRP for the beyondx (G977B and N, maybe other letters too )
Ok. That's all for now. Good luck!

the quick answer is yes it can.
basic summary of the process
activate developer options and toggle OEM unlocking
boot into download mode (might need to plug the phone into a PC not sure) and follow the prompts at the bottom of the screen to complete the unlock.
this WIPES YOUR PHONE COMPLETELY!! back up any files or photos elsewhere.
download the magisk app
download your current firmware or a whole newer update.
copy the AP archive from the firmware to your phone... 6GBs ish
open the magisk app and select to patch a file
patch your AP archive and then copy the newer patched version back to your PC
flash the patched AP along with BL CP and CSC (just to be in not mixing firmware files together).
boot phone and open the magisk app and follow it's prompts to complete the process and that's it.
we have telegram groups for the FE where guys will help you and I'll share a video someone made on rooting the Exynos FE... it might differ from what I've just described if it goes on mention flashing twrp (you can skip that if you want).
