Magisk Canary enables root access on A705F firmware

So this is to confirm gained root access on A705F.

Flashed magisk_patched.tar / following TopJohnWu's installation guide. Everything went smooth. At least for this one.

No TWRP though.

Next step here would be trying A705FN firmware. Since this is the one Grarak, you and the polish user (forgot his name?) seem to use to get Magisk & TWRP working together.

Btw. - just a thought - what did you mean by ASL4 + Jan. security updates ? Sammobile shows A705FN last Pie 9.0 firmware release dated 30.12.19, so what about that Jan. security update? Maybe this is the one that screws up your setup ? Android 10 bootloops many A70s so the rumor goes...
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] fizzingbees:
Nice

Can you link his guide and the exact steps you followed to get root. You can PM me if you want. Also enlist the files you used

For twrp I have been reading, is to follow grarak guide given in OP from step 3 where you flash vbmeta >factory reset in stock recovery > flash twrp > patch recovery.img in magisk manager and then flash it back in twrp under boot.

This was posted a few pages back.

Regarding ASL4 and January security updates, see the screenshot attached.. This is the exact firmware I am running on my phone currently.

It's not android 10.. It's android 9, but with this update the bootloader got updated and now I can downgrade firmware.

Maybe you are right, my firmware is the problem in which case I am royally screwed and can't seem to keep magisk root

In my last attempt, I managed to get magisk running, but the moment I install any module, say activation magisk build in unified host name... Then reboot... I loose magisk
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] ikkanomyoju:
just to be sure

Sent you the installation link for Magisk Root in pm - for others reading this: it can be found in OP or below.

Just to be sure: when you reboot and you say you loose magisk, did you try the key combo as described in topjohnwu's guide ?
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] fizzingbees:
No i haven't

I have been rebooting the normal way

Curiously I can reboot the standard way and magisk would still work fine along with root checking apps.

The moment I install any module, that's when all the problems appear.

Can you clarify this key combo.

I have red the guide and it says to press volume + and power till bootloader splash screen and then release keys to power system with magisk.

Does bootloader splash screen refer to the screen where the devyve bootloader is unlocked appears and it ask user to press power key to continue or is it that A70 powered by Android with this device is not running official firmware screen?
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] MarvinMod:
Just wanted to touch base.

Ive working on a twrp port for android 10 but so far it fails to build. dm_vertify seems to be the issue. I also updated to stock android 10, I flashed twrp 3.3.1-6 and vbmeta, got stuck at twrp splash screen. I was able to pull out of it by extracting recovery.img and vbmeta.img from stock rom, repacking them in .tar and flash with odin. I didn't loose anything and did not have to reflash entire stock nor wipe anything. I will keep working on a port for 10 but don't hold your breath, im not as intelligent as [MENTION=4443334]Grarak[/MENTION]
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] fizzingbees:
Maybe if you and [MENTION=4443334]Grarak[/MENTION] can collaborate. You can work out the bugs and provide us with more reliable root and twrp.

Cuz currently the rooting magisk posted by grarak seems to be proving quite a bit of hassel for certain A70 users. No disrespect intended btw

[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] fizzingbees:
How are you rooted then? Which method
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] MarvinMod:
I haven't tried the root process yet as it requires a wipe. Grarak is pretty busy so he don't have time for this atm but with twrp for 10 not even out yet... :fingers-crossed:
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] ikkanomyoju:
(pm) for others to follow, the question asked was which Odin version & magisk-file were used to get root :

1. Odin 3.14.1

2. magisk-install used to patch AP & flash it. (without TWRP)

Yes, bootloader splash means the first screen you see for a few secs. powering up, the one where you get a vibration & are asked to press power to continue.

hope this helps
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] fizzingbees:
Thanks for helpful reply.

Can you confirm that you can keep magisk root with any module installed and on reboot, say you install viper4android v2. 7 from xda labs. Do you still have magisk root working when viper4android reboots device?

Off topic, since I had so many problems with magisk, I reverted back to stock with bootloader still unlocked and today I received software notification for Android 10 with one UI 2.0 . Firmware version is BTC9 and is with Feb security patch
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] ikkanomyoju:
Go ahead & put the installation link here. A description of what it's supposed to do might also be helpful. I'll use my phone as a guinea pig:D.
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] fizzingbees:
It's a sound driver like Dolby atmos thsr offer very granular control. I'll post link for you.

Just install like normal apk. Grant root, let it install driver and then it will reboot phone.

On boot complete turn on master switch and press this chip button to see if audio is being processed or not.

Report back if the sound driver along with magisk are both working

[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] ikkanomyoju:
does this help you ?
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] fizzingbees:
its not working ,says abnormal driver status

thanks for trying

1st reboot device

2nd reopen app and turn on master switch . its the 1st toggle you see

3rd start playing some music and reopen the app and press that chip icon to see if its working now or not

try with headphones too

question:- did you flashed home CSC or simple CSC along with magisk_patched.tar , BL and CP in Odin?

the magisk you PM is a zip file.

i need your exact magisk manager apk that you used to patch stock AP
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] ikkanomyoju:
1. It works

2. home_CSC as suggested in topjohnwu's guide

3. https://github.com/topjohnwu/magisk_files/blob/canary/app-release.apk
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] fizzingbees:
followed topjohnwu guide . got magisk root succesfully:good:

then i installed viper4android 2.7.1.6 from xda labs. let it reboot device and pressed the volume up+ power combo till booloader splash screen

i again powered down and rebooted with key combo. Now magisk root has lost again and viper4android works.

root apps say partial root.

the same drama repeats itself:crying:

Q)in magisk manager canary , do you tinker with AVM 2.0/Dm-verity, force encrytion and recovery mode toggles ( when you press install and are going to select AP file to patch)?

Update 1= I seem to have partial root. I rebooted the standard way and with the combo key. No change. Magisk still says not installed

On the other hand I uninstalled viper4android, rebooted

Installed old version. And it just worked! No root prompt, no driver installation, just works fine.
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] ikkanomyoju:
no, but same problems with root here also - to me it looks like it's a problem caused by Viper.
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] fizzingbees:
That what I thought. But install any magisk module and root get lost.

Try it yourself

Enable magisk build in unified hosts for ad blocking, reboot and see if magisk still work Cuz it didn't fir me

Am I to to assume you lost root to?
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] ikkanomyoju:
Confirming that after install of Viper4Android, Titanium Backup stops working. Using Root checker throws "super user denied".

Obviously, even with this method - without TWRP - Magisk Root is broken.

As a suggestion, maybe look for a thread that discusses XDA apps & Magisk ?
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] fizzingbees:
I guess we should check Los 17 rom and see if it works for us in retaining root.

IF IT doesn't then I guess it's firmware related issue with our phones.

Cuz nobody else seems to be reporting such a issue both here and on magisk AP patch thread for A70

I kinda miss supersu days when things were simpler :(

I don't think it's xda apps issue.

I installed busybox from magisk repo ( to install very old version of Viper4Android 2.3.3.0 that required busybox back in the days). Rebooting to activate module again breaks root.

Strangely once an app is given superuser access in magisk say to es file Explorer or root checker basic app.

Even with broken magisk afterwards, I get toast notification that said app has been granted supersu access.

This makes me believe that we still have partial root. But somehow magisk fails to run properly.

I am going to check magisk 19.4 and give it a try, if eve that gets broken then I'll try lineage OS 17.

Or go back to stock.
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] Grarak:

I did something wrong and messed up everyting. So, I really need an urgent help to rescue my phone. I did whatever I could but nothing changed. So please, help me.

After flashing the ap with odin, it failed and I wanted to try again. But I couldn't enter the Download mode. It says "An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software."

After that, I opened the smart switch but that didnt work, and as I researched on web, I think samsung removed that function.

Some people were saying that even if it doesn't look like Download mode, it is. So the next thing I did was downloading the official firmware to my computer and unzipping it. Then I connected my phone to odin by doing every step to connect it in download mode (it was still saying an error occurred etc.). I tried to flash every partition. But it stucked at <ID:0/004> system.img.ext4. I downloaded another official firmware from another country but stucked in the same spot. It stucked for 1.5 hour.

I cannot even turn my phone off. It shows error screen. I am really ** up. Please, contact me.

my phone's model is sm-a705fn. If any other information is needed, please ask. I will be online almost all the day for my problem.
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] naruba:
What version of firmware was there? Which one are you trying to flash now? Maybe their bootloaders are different?
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] J.midian:
It says SM-A705FN_1_20190722220140_mqkmaf6ln9_fac. And I don't think their bootloaders are different.

I tried to flash ap only, all of them, each of them one by one. there is no problem about flashing bl csc cp, but it stucks at about %75 when I try to flash ap. I left it for 3 hours (and slept) but nothing changed.
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] FriendlyNeighborhoodShane:
Reboot to download mode by holding all three buttons and do this. Blame vaultkeeper.

Going to try this now. And if this works, you will be the most loved person by me ever.

Well, didn't work but thanks

I successfully flashed the file you showed, but it stucked again when I flashed the official firmware's ap. and still show an error has occurred...
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] FriendlyNeighborhoodShane:
If Odin always freezes at the exact spot then your firmware file is probably corrupted. Try with a new one.

Make sure this is the official signed tar. Only time my Odin freezes is when I try to flash a custom system image
[Samsung Galaxy A70 ROMs, Kernels, Recoveries, & Ot] J.midian:
I already tried 3 differential official firmware but it froze at the same point for all of them.

And then, I couldnt waste anymore time cuz I had to use my phone. So I took it to a Samsung service. They were using a more professional looking software than odin and it too only 10 minutes to fix my phone. They also said that the warrant was still void.

Another annoying day ends btw.

As I understand, it is currently advised against using chainroot supersu. It's not even owned by chainroot any more.

But, yes you are right, things were definitely a lot easier and more robust. Magisk has to use different method because of changed security in Android and that makes everything a lot more difficult and complicated.

Also have that suspicion it might be related to the firmware - but haven't had the time to try the A-705FN yet.

Personally would not want to switch to lineage as it is said to have screen flickering with fingerprint checking - not a good sign.

Curious about how it turns out for you. Let us know.:good:

I have twrp working with android 10!!

Update: seems twrp only works on first boot, after that Twrp hangs. May not be today as im working out the bugs but at least were much closer then before. seems to be an issue with userdata.img. however, apon doing some work with magisk to get twrp working, I found a way to root the device without patching using magisk canary method and you keep root on every normal reboot. it requires using twrp and stock recovery. Ill write instructions on that possibly is a new thread unless you all want me to keep it here. This method DOES work with android 10.

Update 2- apparently I can install los 17.1 with this method as well on android 10 bootloader/baseband update.

update... okay, I can get twrp,magisk and los 17.1 to work with the android 10 update. I can get magisk to work with stock android 10 using a different method that keeps magisk and root upon reboot ( no keys required, no magisk patch, fully functional) but not twrp. I have family stuff to attend to but I will write instructions for both and post tonight. I need to know if you all think I should open a new thred or to keep it here in this one as its not my thred.

Not really a problem.

The screen on the whole kinda flashes when you press on the Fp area, instead of only flashing at the FP portion of screen. And honestly for someone photophobic like me, it's not an issue.

Thing is the rom booted up quite nicely and magisk+ viper4android both works flawlessly.

There is mention of calls issue that I am still looking into.

And I haven't checked the rom fully, but atleast now I can confirm it's Samsung stock firmware issue that caused magisk to break on installing any modules.

Kinda missing one UI and the camera. But Google camera helps, no wide lens photo btw

Yes please

You instructions on Los 17.1 were literal blessing to help me install Los + gapps and magisk on my A70.

If you can make a new thread to root twrp and keep them working on reboot for samsung stock Android 10 or even Android 9 then please do.

Cuz currently the magisk patching AP or recovery img is both failing us.

im not seeing this screen flicker other then the flickering dot in the status bar which is actually the proximity sensor location and is flickering due to some misalignments but otherwise does not effect performance. fingerprint is working as it should for my device and setup. can you post catlogs while reproducing the bug you speak of?

stock rom

Can't give you that, sorry. Not on lineage and not planning to install it - yet, at least. My next move will be A-705F -> A-705FN.

As I use the camera quite a lot and prefer to have full features on it, stock still looks like best option in my case.

you can still pull catlogs on stock. also, my guide walks you through rooting stock android 10. you keep stock android but it will be rooted and root stays after reboot and modules work.

Yeah camera is one department where Los is short off.

Even Google camera can't use wide lens or TOF lens.

8mp photos aren't bad, but they aren't the same as full resolution 32mp ones.

I might go back to stock too. Yes magisk modules break magisk root, but then I have few ideas how to make the most of root access I can get before installing any magisk module and have the root broken. It's quite sad

All you hardwork and time spend fixing bugs is highly appreciated and respected

---------- Post added at 02:15 AM ---------- Previous post was at 02:11 AM ----------

You at on which rom?

How are you rooted? Which method

And by loosing root, you. Mean magisk manager shows magisk N/A?

Which reboot app are you using?

Can you install any magisk module > reboot via the reboot app > recheck magisk for integrity after boot-up.

When you say root is lost, can you at that time open any root app, say root checking app, that was previously granted root access, and check if you get a small toast notification that root has been granted/denied to that app!

Report back with your findings
