[Samsung Galaxy S23 Ultra] Yun2004:
After removing the avb verification of vbmeta, vbmeta_system, vendor_boot and vendor, I can't enter the system normally after flashing the super partition, and I will keep restarting on the boot interface.

I want to make a rom based on the official rom modification by myself, but I encountered an insurmountable problem in the first step. I want to consult some experienced predecessors.

This is just the first attempt of a rookie. I hope to get some help from experience. Thank you very much🙏
[FYT Android Head Units] soliditalstud:
Hey everyone

I have two FTY android head units. Both run 8581a uis

1 no issues installing Navradio but other one says not compatible

Here are the specs u pulled from CPU-Z

Radio installed on rav4 2011

Any help would be much appreciated. It installs fine it’s once I run auto scan that I get the message
[FYT Android Head Units] surfer63:
No, it is absolutely not a FYT unit. It has a 8581 CPU, but it is a K4811 hardware unit, not a FYT unit. Having the same CPU does not mean it is a FYT. (Do you know how many brands of phone come with a Snapdragon 888 CPU? Not compatible either)

I do not know if the K4811 is compatible with NavRadio, but your best shot for support is to head over to the Ändroid Head Units" sub-forum. There are more K4811, and its bigger brother, users.
[FYT Android Head Units] soliditalstud:
Thank you for the heads up. Will do
[FYT Android Head Units] gordgelin:
for now NavRadio is not compatible with K4811 platform

Hi does anyone have an answer for the following problem.

My Samsung charges fine with mains power adapter cable and wireless...but when I use any power bank i get the water in charging port alert !!!. I have tried the battery power banks in another phone and they are ok!!!.

Thanks for any help... think it's a software problem .

My phone is rooted and uses android 9
[Samsung Galaxy S8 Questions and Answers] ace2nutzer:
Yes, it's more or less a software bug.

I've a solution for you, but it's not for free.

You need to flash A2N kernel and activate the full version.

After that you can check "Disable Moisture Detection" in A2N app.
[Samsung Galaxy S8 Questions and Answers] kam1962:
Thank you..but don't have a clue how to flash or what the A2N kernel is. Is there any simple method ?
[Samsung Galaxy S8 Questions and Answers] ace2nutzer:
If your phone is already rooted with TWRP and magisk, then it's quite simple.

check this:

[CLOSED] [KERNEL] [9] A2N Kernel for Galaxy S8/S8+/Note8 (Exynos) [CPU/GPU OC/UV] [Charger Control] [Thermal Control] [R63] [STABLE]

Revive your Samsung Galaxy S8 / S8 Plus phone in 2024! Fastest custom kernel world-wide with lots of innovative features! Supports all S8 / S8+ Plus / Note8 Exynos Variants Running Android 9 A2N Kernel Special Features Google Play - certified...

xdaforums.com

you only need to download the proper a2n kernel for your device model.

Then you copy the kernel_zip to your phones sdcard and you flash it over TWRP recovery. After that you can flash magisk in a row to restore root which is required to apply the fix. Finally follow the instructions from the red a2n app. You will find the setting that you need in "Power" menu.
[Samsung Galaxy S8 Questions and Answers] kam1962:
Thank you...i do have magisk but not sure about twrp... still unsure that I could brick the phone

@Ryujin96 or @TechNoobForSale

Could you guys please help him to flash a2n kernel on his phone?

Please noob friendly.

@kam1962

what is your phone model? "SM-G950F"?

Those users from the a2n community will help you.

I will look around on YouTube etc and see what can be done, now I know its the moisture detection software. Thanks for all your help
[Samsung Galaxy S8 Questions and Answers] Going1438:
I wonder this detection/alert might be a recent invention, when does this thing first introduced?
[Samsung Galaxy S8 Questions and Answers] kam1962:
It happened walking in the rain. Phone was in my pocket and did get wet. Took about 4 days for the charging port to start working..wireless was ok but power packs have not since that day

[Samsung Galaxy S8 Questions and Answers] Ryujin96:
Welp i saw @TechNoobForSale is volunteer for it🫡
[Samsung Galaxy S8 Questions and Answers] ace2nutzer:
It's a feature from Samsung. But no idea if it started with the S8 or with the S7 or so. But can be found out in kernel source code. I've developed a way to ignore that warning in kernel because there was another user with the same issue ... basically moisture detection even the fact that the port is dry, that's why I allow my users to disable this feature if the port is dry and the warning still appear. ;)
[Samsung Galaxy S8 Questions and Answers] kam1962:
Thank you all for the help. Still a bit worried about flashing but will think about it. Just ordered a wireless power bank (morphie) think it could be an easy work around ..again thank you all

How to revert OnePlus 12r back to oxygen OS 14 after flashing unoffical pixel os rom?
[OnePlus 12R / OnePlus Ace 3] miku404:
To do this you need to re flash the original OS you can find it here OG OS use something like TWRP this is a version for the ace3/12r (yes it does work for both phones) then with TWRP you have to flash the stock OS to both slot A and B and that about it. If you want to re lock the boot loader and make it so its a completely stock phone that you can sell you might want to try this post.

Hi, I desperately need help with this phone. I flashed blank a vbmeta to disable verity and verification, but, The phone is a nice paper weight now as i flashed files on it that were for a HD65 Plus or something like that as they had been marked as "Ultra" files. Anywho, I have searched the web universe best as an old blind guy can (even with Ai) and the firmware or "ROM" for this Unicorn is non-existent. If some kind Soul could hook me up with the "Vortex HD65 Ultra" factory "ROM" or firmware, I would be eternally greatful as I was just trying to fix it up for my new Buddy. Any help would be appreciated as I'm poor AF and I cant afford to buy this dood a new phone. I learned my lesson :(. Please help meh......

I just got the Vortex HD65 Ultra, and was surprised that it came ready to Root out of the box considering mine was a free government issue for today's Obama Phone equivalent.. It's definitely not my Pixel 8 Pro but I will have fun with it anyway..

That being said, I used MTKClient in BRom Mode to make a dump/backup immediately after reading this thread.

I was able to Root the HD65 Ultra through usual means via Magisk 27.0.

However, every time I try to fix DM Verity Corruption by means of any version of these codes my device soft bricks:

fastboot flash vbmeta --disable-verity --disable-verification vbmeta.img
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
fastboot flash vbmeta vbmeta.img --disable-verity --disable-verification

Attached is the vbmeta_a and vbmeta_b, as well as the boot_a and boot_b images.

If anyone is able to fix DM Verity Corruption please post the method, Otherwise I will just continue to hit the power button upon boot.

Also, I have a complete dump/backup (Firmware) file if needed, Download Here. I went ahead and removed the nvram and nvdata image files as flashing these on Mediatek devices tends to have an adverse effect in removing the IMEI and Baseband.

Cheers!!!

[Android Q&A, Help & Troubleshooting] F8L3RR0R:
Well, I thought i was smart enough to finger out the MTK stuff as i have successfully saved my OnePlus 6T. I can only guess i need a samsung EDL cable since it seems to be a clone or I just cant figure out the Konami code to get it to work. I have it in Dev Mngr and meta util "pretends" its doin stuff but not. and MTKclient is just a flatliner cant find it at all. got the 5. w/e drivers universal mtk etc etc. Have the battery out. And Im just guestimating from reading and my other phone, that I hold down all buttons. Anyways, Yall done so much i cant believe it, but sadly I need a favor as to how to get EDL mode poppin on this so I can fix this guys phone and get some cred back. Ty again.
[Android Q&A, Help & Troubleshooting] Justadudeinspace:
Yeah guys, use MTKClient, MTKClient is a Shell based flashtool that operates like Platform-Tools (adb and fastboot) but in BRom mode on Mediatek devices only.

Open the shell in the Platform-Tools folder by usual means of typing CMD in the search bar of the open folder.

Should look like:

C:/platform-tools>

Download Instructions, (I used Windows Install) Download to the Platform-Tools (adb and fastboot) folder.

Repeat opening MTKClient the way you open adb and fastboot. Go to the MTKClient folder and type CMD in the searchbar.

Should look like:

C:/platform-tools/mtkclient>

Next, Enter this code into the shell and press Enter:

python mtk wl <Path to firmware folder>

Once the code is active and searching for the device, follow the next step.

For a single file flash type in this code:

Example:

python mtk w boot_b <Path to boot image>

NEXT STEP:

Once the full Install is complete and the code is entered into the shell, make sure the device is powered off completely. Then press and hold both volume bottons. Then press and hold power also but plug the device into the computer right after pressing and holding power. You should hear a Ding of the connection on the computer but the screen on the phone will stay black. This is BRom mode.

May have to repeat a few times to get a good connection but once you do MTKClient will flash the enter folder or file in BRom mode.

*If In Bootloop*

Try to time pressing all the buttons and plugging in the device when the device powers off. You can achieve a connection this way.

That should fix your issues and bring you back to new.

Man, I get it to show up in the device manager but when i try to use mtkclient or other tools, it like resets and the device now has a ! by it. Cant seem to get it to work....
[Android Q&A, Help & Troubleshooting] Justadudeinspace:
Try charging the device and keep trying to connect in BRom mode when the device powers off. This is the only way at this point without sending the device in. Sometimes it's hard to get a connection but make sure you enter the code into the shell first.
[Android Q&A, Help & Troubleshooting] Justadudeinspace:
I'm going to go ahead and warn everyone that the Vortex HD65 Ultra is Garbage. It only has 3GB of RAM, and really it can't take much modding. I have only applied a few mods, and the phone keeps freezing up. I used ZRAM mods to improve the RAM performance and it still freezes up. The phone is basically crap in the modding world. I suggest leaving it like it is "Out of the box."
[Android Q&A, Help & Troubleshooting] Justadudeinspace:
I have not tried it personally. I just used the vbmeta from the device.
[Android Q&A, Help & Troubleshooting] F8L3RR0R:
so for brom mode we hold both volume keys and power key as it is powering down? Also it seems the phone keeps turning off and on every like 10 secs or so. Is that normal?

Ya I was trying to make it run better for my Buddy but I misread and ya its bad lol. Honestly Im starting to wonder if I dont just buy him a new one and we "pretend" I fixed it lol.....
[Android Q&A, Help & Troubleshooting] Justadudeinspace:
BRom mode is "all keys" on the phone pressed while the phone is powered off, and plug the device into the computer-also while powered off. If the device is stuck in a bootloop, you just have to time it to when the phone is powered off. Sometimes I have to unplug and re-plug the device back in immediately after my first try. It can be tricky. Especially if you are not familiar with it.
[Android Q&A, Help & Troubleshooting] Justadudeinspace:
Noble effort my friend but I believe the best thing you could do is put the phone back in it's original state and give it back to your buddy with some rare apps or something. Teach him to use Shizuku or Root it and only use Root Apps that don't require Magisk Mods, because Magisk Mods completely overload the phone.

Steps To Remove DM Verity Corruption

Credit: ShazuxD
[Android Q&A, Help & Troubleshooting] Justadudeinspace:
You know, if you just hold volume up and the power button upon powering up the HD65 Ultra, you should be able to then select between recovery mode, fastboot/bootloader, and system startup. Select fastboot/bootloader, and then flash the normal vbmeta that I provided in my original post to un-brick your HD65 Ultra. That is if the vbmeta.img was the only partition file you flashed over.

It won't fix the DM Verity Corruption but it should fix the brick. I have tried to fix DM Verity Corruption by following the path:

adb reboot bootloader

fastboot devices

fastboot oem cmds

Failed!

So I tried the next step in flashing the vbmeta.img partition file with both the pulled copy from the dump file as well as a blank version following the path:

adb reboot bootloader

fastboot devices

fastboot flash vbmeta --disable-verity --disable-verification vbmeta.img
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
fastboot flash vbmeta vbmeta.img --disable-verity --disable-verification

Failed!

Next I tried to use the adb shell command through the computer by following the path:

adb reboot "dm-verity enforcing"

Both with quotations and without.

Failed!

EDIT: I tried to use the same command through a Rooted Termux terminal:

su

reboot "dm-verity enforcing"

Both with quotations and without.

Failed!

So next, I tried to use these fastboot codes:

fastboot devices

fastboot oem disable_dm_verity
fastboot oem enable_dm_verity

Failed!

I will continue to try new methods until I succeed or run out of methods to try.

Ok, lol old fart.. I'm old as well, and I have definitely had a few dings to the noggin over the years. Why it's amazing that my noob tail understands any of this stuff at all considering the copious amounts of substances I have ingested, I'm sure a few elephants died in the process.

With that being said, EDL mode is to Qualcomm as BRom mode is to Mediatek. So if you're in EDL mode we are having some major other worldly technical difficulties, hahaha.. Does this mean that you actually achieved entering BRom mode? Or have the great Android Gods presented me with a new curve ball that I could not see coming?

You are indeed welcome, the older I get the more helpful, patient, and understanding I try to be. Though I fall short some days. I am the only Android fanatic in my area. I'm considered the expert around here, and I'm like you guys have no idea how green around the ears I still am. With that said, if you have any more questions, I will do my best to answer them.

OK, there's no way I can recommend you going through such an operation as messing with the test points on a device. This is hardware tampering. one false move and you run the risk of destroying the device. Do so at your own risk.

With that being said, this was a level up for me. I can see me testing this. Just need detailed research on phone schematics. Thanks for the share. Definitely do at your own risk with that one.
