[Samsung Galaxy Z Fold 4] blackhawk:
I've used SmartSwitch's predecessor, Kies. It was worse. It only takes one screw up by either to make a huge time consuming mess to clean up. Worse critical data may end up being lost.

It may be an incompatibility with that OS version.

Make sure the app is updated. Sometimes clearing its cache and if necessary data can resolve issues.

It's always best to do a clean load. I don't upgrade or update my firmware as that can easily screw up an otherwise good load. With a major firmware upgrade you should do a factory reset.

This stock N10+ is still running on Pie, last update was over 3 years ago. The current load will be 3yo in June, still fast and very stable with minimal maintenance. Security simply is not an issue; no malware in that time frame. This is what Android is capable of, it can be a very robust OS.

There a few things I do to mitigate the chances of existing security holes. Wifi is always disable, I run a firewall, use only Gmail and most importantly I'm very careful with any apps I install. Any side loaded ones are scanned with online Virustotal; any doubts they don't get loaded. All apps the absolutely don't need internet are firewall blocked. I don't allow apps to update either as that's a known payload upload strategy that's happened more than once.

Brave browser* is my primary browser as it's near bulletproof. I also use this DNS setting to globally block app adware and some blacklisted sites.

View attachment 5834925

*I'll back out of bad sites if that fails I'll close the browser, reopen and try to close that tab. If that fails I clear the browser cache and if all that fails I'll clear the browser data as a last resort. I had to do that only once with the Samsung browser.

I also police the download folder daily for anything I didn't authorize. All files are vetted before being moved into the database. At the minimum I'll open jpegs to make sure they are clean. I've encountered a scripted jpeg on Android; damage was minimal as it was caught in the download folder. Had it made it

Into a larger folder of files it would have made a mess. Best to store files in a folder as it acts as a firewall to this type of malware. That's how I handle media files like mpegs.

My backups are complete and time staggered on separate hdds and flash drives so even if one gets compromised I don't lose all my data. All critical data is redundantly backed up multiple times and stored in different locations, off line.

Develope a plan, think it though and implement it. Digital data can be very fragile...

My device is bricked with no fastboot. The only thing working is edl. But xiaomi has put an edl authentication for flashing. The authentication is put into prog_ufs_firehose_sdm855_ddr.elf.

Is there anyone has the firehose programming patch for MI 9?
[Samsung Galaxy S8+ Questions & Answers] zeroturnpete:
I have an S8 that I want to run some services on. The problem is this phone has a completely broken screen. I currently have it connected to a tv with a keyboard and mouse. (Notably the touch sensitive part of the display still works). Is there any way to root and install Linux based OS with this handicap?
[Samsung Galaxy S8+ Questions & Answers] _allaie_:
Possibly yes. If you manage to install custom recovery that's it. Then you can proceed with any custom OS

Hope it helps
[MTCD Android Head Units General] esmeraldo18:
hello. I recently changed my car's 4 speakers and I measured the polarity of them while wiring and it turned out that rear speakers output is the opposite. I confirmed it by removing the head unit and measured it with a multimeter and both rear left and right + is - fronts are ok. did they do it on purpose or it is a factory fault? I'm planning to crosswire the extension cable. did you notice something like this?
[MTCD Android Head Units General] Renate:
Huh? How did you measure with a multimeter?

Did you play a low frequency tone and check the voltage between the FL+ and RL+ on the AC range?
[MTCD Android Head Units General] esmeraldo18:
I turned up the volume and checked the dc voltage between RL + RL - and RR+ RR- multimeter showed - signal. for fronts it didn't show - .
[MTCD Android Head Units General] Renate:
No, that's not really a test. There might always be a little residual DC (at least as measured by a DC multimeter on a complex signal).

There are a zillion ways to check stuff, some just the electrical out of the HU, some the acoustic polarity out of the speaker.

If you put a signal into your HU you can compare the phase of the input signal vs that of a microphone sequentially in front of each speaker.

A low frequency assymetric wave can allow you to visually see which way the speaker cone is moving.

So that I wouldn't be caught out, I just checked my computer setup.

Channel ID came first, making sure that left is left.

Then I put 440 Hz tone out the computer.

Instead of locking to the PC output, I used a precision test oscillator which was certainly close enough to stay locked for a minute.

I used a microphone and compared the phase of the two signals.

I switched the microphone from in front of the two speakers alternately.

I could see that they both had the same phase.

The top trace is the microphone, the bottom the reference.

Ok, back to reality. You can check for electrical phase out of the HU by adjusting the channels evenly and connecting a speaker temporarily between FL+ and RL+. You should hear practically nothing out of the speaker.
[MTCD Android Head Units General] esmeraldo18:
so if I connect a speaker between FL+ and RL+ and hear nothing, does this mean polarity is correct. because I always measure the same polarity with multimeter for rears and same for fronts. I was completely sure that something is weird.

I tested this because when I turn up the volume for fronts only it has deep bass and good sound but when I start to turn up rears at balanced stage I hear no bass and when I turn up rears completely with turning down fronts I hear also deep bass. when the volume is balanced rear and front speakers cancel each other, that's why I tried to measure them, because I thought I connected speakers wrong but they were right so I removed the head unit and measured it also.

I used this video as a guide;
[MTCD Android Head Units General] Renate:
Well, it does sound like a phase problem.

If it is, then switching things anywhere will fix it.

But if you want to treat this as a research problem you can look into exactly where this problem is.

Are the front and read speakers the exact same model?

It could be the HU, the wiring, the speakers.

Yow! That's just wrong!

You cannot tune in your radio station and measure DC on speaker cables!

It's like a blind man measuring the size of an elephant by touching somewhere.

Your multimeter is taking a signal that changes thousands of times a second and trying to represent it with a number!

Yes, what he did with the little battery and the speaker is fine.

If you have a spare little speaker, hook it up between the FL+ and the RL+ with the F/R balance at zero.

It should get loud at all front or all rear and be quiet in the middle.

You can also check FR+ and RR+.

Then FL+ and FR+ (using normal L/R balance).

This just tells you that the HU is correct.
[MTCD Android Head Units General] esmeraldo18:
I got you. All I'm saying is I'm not trying to read some values or catch something with multimeter, it does not show a static number though. But it always shows same polarity no matter what radio plays. Isn't it something worth relying? And I'm pretty sure that hu is faulty because I'm measuring directly over the pins inside sockets and at the top there is a diagram that shows which pin is positive and multimeter gives negative results for rears. Fronts are ok. These units are mass production so I'm afraid many users have phase problems they don't aware yet.
[MTCD Android Head Units General] esmeraldo18:
I tested this, speaker was very quite when balanced at zero and loud all front or all rear. So what does it mean? Both cable is + and it shouldn't play anything right? But it plays when I change the balance?
[MTCD Android Head Units General] Renate:
It's showing nothing.

Moreover, since this is switch mode (class D) amplifier the signal is actually switching at 200-400 kHz.

This means that the phase out of the HU is correct.

It's what I'd expect. It's pretty easy to get the design correct once.

Then they can make a million units and the phase will always be correct.

As I asked, are the rear speakers and the front speakers the exact same model, wired the same?

You can shrug your shoulders if you like and just switch the wiring so that the base is reinforced.
[MTCD Android Head Units General] esmeraldo18:
No, front and rear are different, because the diameter is different but I double checked the polarity before changing them and I'm pretty sure they were ok.

Update: Renate you were right, changing polarity made things worse, I believe lack of bass is related to another problem, probably different type of speakers causing this. Fronts are 16cm jbl stage 3 627f and rears 13cm sony xs-fb131e. I understand that using multimeter is wrong, thank you.

[General Questions and Answers] Captain_21:
So I have a Samsung Galaxy s10+, I recently noticed that my SD card is not recognized by my phone as encrypted. All files are there just can't open anything. I've tried restarting the phone wiping cache partition, and a few free recovery software. I can see the files and file paths I just can’t Open them. I also notice that on the sd card there is no .metaEcsFile I'm not sure if I deleted that file but I do remember deleting a .metasomething file. But it was in my recent files and I'm pretty sure it was recently created date and time wise to when I deleted it. I'm not certain if that was the cause of the problem or not as I didn't check my SD card till some time after that file had been deleted. There are 2 things I haven't done that people have said work and I'm worried they will mess up the SD card and make any data recovery impossible. One of the things is to "encrypt" the SD card which would work if there was one key per device. But I'm not sure. The other thing is to copy data to a PC, format the SD card, encrypt the empty SD card, and put the files back on the SD card.

Many people said that updating to the October patch would fix the issue I was on march of 2021 security patch when this happened and updated to October of 2022 patch. There is another update however it says you can’t downgrade so I haven’t done it Incase I need to downgrade.

Any help would be appreciated very much.

Thank you.
[General Questions and Answers] blackhawk:
Never encrypt SD cards... or backup data drives.

Personally I would reformat the card and start over, unencrypted. If you don't have the data backed up you're boned to a greater or lesser extent.

Sounds like you lost the folder encryption key. They may be able to be decrypted but it will be a pain. I think each folder uses a different encryption key although I may be mistaken.

Firmware upgrades and updates can and do break Samsung's. If you insist on doing either it's imperative to have all critical data redundantly backed up first, as it always should be anyway.
[General Questions and Answers] alecxs:
get a card reader for PC, use testdisk or runtime GetDataBack for (ex)fat and try to undelete .metaEcsFile

I ha some trouble after flashing Universal GMS Doze. The easiest way was to flash they full system.

So, there are two things which i noticed, and one one of them is very annoying.

1. In the Settings -> Connections -> More connections settings -> "Nearby device scanning" is now gone. But now there is a option in Settings -> Connections -> "Ultra-wideband (UWB)"

Is that new? Are these two the same?

2. It seems, that ether the app "Threema" (Messenger) or the System is using the wrong volume for the notifications. If I set the Notification volume to the max or mute, the incoming notification do not change the volume. Instead its the System volume.... WTF?

How is that possible? In the app settings, there is the right notification sound active.

I am sorry to tell you that in Chinese version it is not possible to have android auto, nearby or any other google service because they need to have all the elements of the company installed in system.

The only way to use it is in two ways:

- With root: installing Gapps

- Switch to US ROM: I have the Chinese version (without NFC), but I could move it to US version without problem, this one has Android Auto and all google services.

[Realme GT Neo 3] TuLy2702:
I realized that updating version to Android 13 realme ui 4.0 using image flash method will cause brick even hardbrick, downgrading ota to Android 12 version really isn't safe anymore . The main cause is due to the bootloader version of android 13. In this post I will show everyone how to downgrade to Android 12 and make rom transfer from rmx3560 to india version rmx3561

The article I have detailed and easy to understand is pinned by my group

How to downgrade Android 13 (realme ui 4.0) to Android 12 (realme ui 3.0):

STEP 1

1. Download app OPLU see link (I am not authorized to post links here. Instead the app name OPLocalUpdate_For_Android 12)

2. Download the roll back package in your phone and remember the location (leave it out of main memory, not contained in any directory)

3. Open app OPLU - select the setting icon in the top right corner - You will see the downgrade file there - Click select package and click update (it will say wipe all data after update)

4. After restarting the phone, the phone is set up normally, but please download the OPLU application again and download the update package (usually I download the downgrade package, I usually copy it to my computer).

5. Repeat the downgrade operation but still use the downgrade package you just used - Wait for 100% progress and the phone will factory reset one more time.

STEP 2:

Advanced downgrade: required unlocked Bootloader

1. After doing the 5 steps I mentioned above, find the OTA file (zip file that contains payload.bin) of your device and download it to your computer and remember the location.

2. Download Fastboot enhance from github source

3. Plug your phone into the computer - Boot the phone into fastbootd with the command: adb reboot fastboot

4. You will see an interface with China language - you choose English and it must be Fastbootd

5. From the computer screen open Fastboot enhance - you will see on it display the serial number of devices

6. Extract the downloaded OTA file and on the Fastboot enhance screen select flash payload.bin.

–> Wait for the green progress bar to run to 100% then success.

8. On the phone screen we select "wipe data" - Enter the wipe code - Select yes

9. Wait for the phone to reboot => Successful downgrade 🤗

(You can use this to flash other firmware)

[Samsung Galaxy S23 Ultra] therealashish:
Hi everyone.

I've pre-ordered an S23 Ultra and have also purchased a 2 year Samsung Care + plan. I've been using a OnePlus 5 from 5+ years now and the last Samsung device I used was Galaxy S2.

Since Samsung's warranty becomes void if the Knox is tripped, my question is, in case there is a screen/ hardware damage to a rooted device, can it be claimed for repair/ replacement under Samsung Care+?

Because in case a rooted device will not be considered under Samsung Care+ plan too, I think I would prefer to cancel the plan. I'm looking for your suggestions on this. I am located in Canada.

P.s. I see the following exception point mentioned in the T&C's of Samsung Care+, "Device malfunction or damage due to improper installation on, or improper equipment modification to the device."
[Samsung Galaxy S23 Ultra] blackhawk:
It's up to Samsung. They may charge you for a new mobo as part of the repair. I would use abd edits to optimize it instead.

Drops will likely be it's biggest enemy; use a good case. These are heavy, corner hitting, face planting happy phones when dropped. With no case a 3 foot drop onto concrete will likely damage it.
[Samsung Galaxy S23 Ultra] peacey8:
You can't trip Knox or root your phone on the Canadian or US S23U. And Samsung Care+ in Canada is only for Canadian phones. So I'm not sure why you're even worrying about this problem?
[Samsung Galaxy S23 Ultra] amirage:
How can you not trip Knox when rooting? Isn't it an electric fuse that trips when the bootloader is unlocked and rooted?
[Samsung Galaxy S23 Ultra] Joloxx9:
I guess they can't unlock bootloader so no chance for knox trip.
[Samsung Galaxy S23 Ultra] amirage:
I

Isn't necessary to unlock the bootloader to root the device?
[Samsung Galaxy S23 Ultra] Joloxx9:
It is necessary and unlocking bootloader trips knox
[Samsung Galaxy S23 Ultra] amirage:
So, this goes back to @peacey8. How is it possible to not trip Knox when unlocking the bootloader unless there's a country regulation stipulating this?
[Samsung Galaxy S23 Ultra] EtherealRemnant:
There currently is no way to unlock the bootloader in the US and Canada. Additionally there is no working root exploit for these phones. It should be near impossible to trip Knox in the locked state. So it's nothing to worry about.
[Samsung Galaxy S23 Ultra] blackhawk:
Unlocking the bootloader doesn't trip the Knox efuse, loading an unauthorized bootloader does.

Apparently paid services have been able to unlock the N10+'s and maybe other Snaps. I'm not that interested so haven't followed this too closely. The remote service could potentially install malware and I refuse to risk bricking a valuable device.
[Samsung Galaxy S23 Ultra] marvi0:
Hi what's abd edits?
[Samsung Galaxy S23 Ultra] Abaddon:
It's up to the person checking. Some may take it in for warranty even if the knox is tripped but some won't. I've had that experience before.
[Samsung Galaxy S23 Ultra] jcsww:
Using ADB commands to remove bloatware is probably the most common example.
[Samsung Galaxy S23 Ultra] peacey8:
You cannot unlock the bootloader on North American variants. Only European. So my point is this question is moot, not that Knox won't be tripped if you unlock bootloader.
