Hello all

I have purchased a chinese MCU recently, it works fine but the sound is low comparing to the original MCU.

i searched a lot on the internet to try and find if there is maybe an update to the firmware or android version but its really confusing and i though maybe someone here will be able to help maybe finding firmware and android update to the MCU, or maybe a way to boost audio output With an app or something.

i have the latest version 7.3, now it has a separate application for the equalizer, but the audio output strength depends on the audio chip, I am a manufacturer and there is an option to manufacture with DSP (digital sound processor) this one does sound much louder than the original
[Android Head-Units] ZaKzOuKer:
Hello @Darkhack3r77

When you say Latest Version 7.3 do you mean android version?

and is it possible to change this one audio chip ? os should i purchase a new one that supports DSP?

FAQ

Q: Can i use this recovery with other firmware then mentioned in compatibility?

A: Only with same Android version or Rollback protection might kick in and you won't be able to pass the lockscreen.

Q: Where do i get vbmeta.img?

A: From here, download the one you need according to install instructions.

Q: TWRP can't mount data partition, what to do?

A: Make sure you formatted data partition.

Q: Phone is not booting even after 20 minutes

A: Try to reboot. If still not booting, make sure you flashed multidisabler zip / formatted data partition.

Q: How to format data partition?

A:

Q: Phone is showing only Samsung logo

A: Try to reboot. If still not booting, consider installing an older TWRP build or a more recent firmware. If you still don't succeed, post here some details about your device and previous firmware and we might be able to help.

Q: Why do i need to format data partition?

A: Because old firmware encrypted your data partition and new rom can't decrypt and use that content / root needs access to data partition to place misc files / phone not booting after flashing root until data partition gets formatted.

Hello,

When flashing the multi disabler 3.2 there's a log message :

"Disabling restoration of stock recovery... Found /vendor/recovery-from-boot.p. Disabling... Failed."

Is it normal ?

EDIT : I rebooted and lost TWRP, when I went back into recovery it was the Android one.
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] corsicanu:
I'm still trying to find the issue, for whatever reason multidisabler needs a second flash to work as far as i seen on my device. So for now please flash multidisabler 2 times in a row, until i find a better solution to this.

I did this with my S10e and S10 without a hitch. They were SM-G970F and SM-G973F. Now I have an S20, SM-G9810. I flashed Hong Kong firmware (CRC TGY), Android 11, G9810ZHS3DUL3 (because I am trying to use microG in place of play store, which I was able to do on both the previous S10 models).

This is not working. After I flash the magisk patched AP (with CP and CSC and BL), reboot to download, then TWRP (x1s) in AP and vbmeta_disabled in CP successfully, but when I hold Vol + and Bixby, this is the error I receive:

I have USB debugging enabled. I have root access. But, I cannot use Odin to flash TWRP. I tried adb sideload also, even after granting ADB root permission in the magisk manager (but I don't know if that includes recovery ADB sideload). The recovery was the stock recovery as I cannot flash TWRP.

i have the problem that i cant boot into system anymore after flashing twrp. it always boots to recovery.

factory restet or wipe date after flashing twrp didnt help.

btw ill try to install it to Android 11. shouldnt that work too? cant find any other working guide for twrp on S20 for Android 11
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] corsicanu:
What if you try multidisabler this time?

oh of course i installed that too. forgot to mention.. still no success
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] corsicanu:
Unfortunately i don't know what to tell you, specially since you're on Android 11. Is there any particular reason for using that version?
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] J0KER!:
i dont like some feature of Android 12. the battery drain is higher too.

i nailed the problem down to the Wipe data step.

before i do that i can boot into system without problems. after wiping its broken. but without wiping i cant use internal storage with twrp. so i'm really confused what to do here

Edit. Its the same when i do the factory reset via system (not via TWRP). i cant boot back into system after.

Hello i have simcard problems no signal etc. Is there anyway to flash back to stock firmware ?
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] xbt-:
Of course. Just download the stock firmware and flash it in ODIN. If your data is backed up you can use CSC instead of HOME_CSC and it will repartition for you too to resolve any errors.
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] xbt-:
I wanted to confirm that when I did everything all from stock,

1. All this https://xdaforums.com/t/how-to-exynos-snapdragon-root-s20-series-and-upgrade-firmware.4079353/

2. All this thread, with the final step being Wipe, and I am on y2s with Android 12 / OneUI 4.1 on a G985F/DS Exynos (S20+),

Then I personally did not experience any issues.

It will however require you to re-setup your phone and reinstall Magisk Manager. Since wiping the data will factory reset your phone.

However, I did not have to root again. I only needed to install the Magisk Manager again.

It is probably because this is for Android 12 and you are on Android 11.

Hi guys

Trying to install TWRP on my S20+ on Windows but I can´t pass the FILE ANALSYS! :(

I´ve tryed several cables and several Odin versions.

I´ve installed Samsung Drivers, the OEM it´s ON and so the USB Debugging.

I´m on android 13

What could be happening?
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] dope77:
Still not working? Just upgraded to android 13 and it's working without issues.

Put the recovery in AP and vbmeta.tar in CP, disable auto reboot then flash from Odin.

After flashing is done, hold power + volume down till the device restarts then quickly press power and volume up to boot recovery. Format data then reboot recovery then Flash the multi disabler followed by magisk then reboot
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] dope77:
You can download the rom then extract it, copy the AP file to your device then patch it with magisk. After that copy it again to your laptop then flash your firmware as usual but use the patched AP and HOME_CSC instead of CSC to keep your data. And don't forget to baxk up your data in case something happens
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] altojd:
thanks for your reply which doesn't answer my question. i knew how to install new rom with odin and how to root it. my question was if i can flash new adndroid 13 WITH TWRP already installed on my phone. As fpr now i managed, installed A13 with odin, then i flashed twrp 3.7.0 + vmeta and after flashing magisk zip i have rooted phone again

Mine didn't work with an S20 and TWRP 3.7.0 either. Finally figured out it was from using the wrong version of vbmeta.tar. I used the one called vbmeta_disabled from this thread instead: https://xdaforums.com/t/how-to-exynos-snapdragon-root-s20-series-and-upgrade-firmware.4079353/

sm-g985f on android 13 (wb1) and rooted with magisk manager 26.4 and patched my boot.img and vbmeta.img

used odin to flash that firmware.

do i need that multidisabler file?

what does it do?

also from here if i want to install twrp what are the steps

does zygisk need enabled? i uninstalled or disabled everything that i could from the ui.

everything.

trying to make it as much like a raspberry pi as possible.

wish there was a debloat script for that

finally to my main question.

how do i install twrp at this point?

is multidisabler for twrp?

i would like to update to the latest android update i can do but still have twrp work fully and magisk too.

right now i havent had anything tell me im not rooted and google play does work still
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] en11gma:
anyone jump in on the question above? i ask in this separate reply because i keep editing the post above and i dont think anyone has read that yet
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] xbt-:
multidisabler is recommended

it does a few things including I think bypass rmm state and vbmeta, look it up just do a search what's in there. But yes you should use it.

zygisk had nothing to do with recovery so no you don't need to enable zygisk in magisk before flashing twrp

look up exact instructions for installing twrp for your device

multidisabler can be flashed inside twrp

if you have magisk installed then you are rooted
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] en11gma:
i installed stock rom Android 13 (WI7) Security patch level 10-01-2023.

i then rooted by magisk manager patching boot.img and vbmeta.img out of my stock AP file from the tar.md5 i got from samfw.

i made a tar file of those 2 files with 7zip and put in odin AP slot.

rebooted to the stock recovery and factory data reset.

im rooted and everything work ok.

i mean the filesystem is encrypted and selinux is enforcing but i guess thats normal with stock

ok what are instructions for flashing twrp in this scenario?
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] xbt-:
flash multidisabler too

twrp can be installed if your bootloader is unlocked.

to remove encryption see here, it might help

[FIXED] How to remove data encryption in TWRP

Users of TWRP 3.1 on Doogee Mix (including myself) faced the mammoth problem of an encrypted storage after unlocking the bootloader and flashing the custom recovery. This problem is not peculiar to the Doogee Mix, any other device with TWRP 3.1+...

[Galaxy EXYNOS S20 S20+ S20 Ultra Development] en11gma:
instead of using magisk or twrp (they both fight for patching boot).

for vbmeta.img shouldnt we just need to do:

'fastboot flash --disable-verity --disable-verification vbmeta vbmeta.img' and be done with it?

than magisk patches boot.img and ramdisk while twrp patches boot.img and uses multidisabler?

when using these two together there is one going over the other. i found a good thread where it is explained alot better.

pst number 57,767

#57,772 is how he did it.

its more complicated than what is being said.

i still think the 'fastboot flash --disable-verity --disable-verification vbmeta vbmeta.img' should be used as its our own vbmeta.img

its not that simple. they are definitely fighting over control.
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] en11gma:
right now on the sm-g985f/ds with Android 13 stock WI7 but rooted with magisk 26.4

everything is working great.

i debloated 237 apk files. 227 uninstalled and 10 disabled.

if i download twrp apk will it install correctly?

if so at one point to install multidisabler?

will i lose all my /data

will FS be decrypted?

ok so i just flashed stock WKD

i then installed magisk manager v26.4 (but only to patch the AP file out of the stock firmware) in case i want to use it. im not flashing that patched file (just for backup).

im now ready to install twrp for my y2s device.

i got both the 3.7 img and tar file from twrp.me

i think i have to find a vbmeta because from what i read the one in the OP does not work???

Good morning all,

I'm writing you because I need information about custom roms for Galaxy S20.

now I own a G980F/DS model and i'm searching for a ROM that manages the multi user login (what i mean is that I want to login to my phone with different users the same way I do in a computer): does the custom ROM do that?
