[Samsung Galaxy S24 Ultra] Hurt Copain:
Hello,

I am curious if there has been any reports maybe on previous s22,23, or even s24 ultra devices where the unlockable bootloader versions aka international (B ending models) ie S928B or previous model iterations have been used in the US and if the US only band 71 which kmovil states is missing has been enabled by flashing the US models CSC..

This is something I am considering in buying and there have been whispers that previous devices the inactive bands can be activated should the correct csc be flashed. Any insight into this would be appreciated.

Thank you in advance
[Samsung Galaxy S24 Ultra] zeroktal:
It wasn't the correct CSC. There is a band unlock for the s23U, but the s23B already has them all unlocked(that exist in the modem) at least near as I can tell.
[Samsung Galaxy S24 Ultra] Hurt Copain:
Great, thank you. That was my understanding as well.

[Samsung Galaxy S21 Questions] Win_7:
this is incorrect if you want to downgrade then you spefifically do not want to update since that can block you from downgrading

and also you do not need to unlock bootloader or trip knox just to downgrade if the bootloader version allows you to

[Android Q&A, Help & Troubleshooting] h1ermis:
I know it used to be a thing back in the day, like about a decade ago. And it was lovely. Having two ROMs was awesome. Now, with how fast and capable phones are, I would expect them to be able to run even more ROMs. If this is no longer a thing, why is that the case? Did the demand for this just disappear? If it does exist, which current phones have multi ROM available? Thanks in advance. https://9apps.ooo/
[Android Q&A, Help & Troubleshooting] Revontheus:
The differences between custom ROMs are down to the features they have. Nowadays, most custom ROMs have similar base features with minor differences between each other. Also, the complexity and space requirements of implementing multi-boot is not worth it.
[Android Q&A, Help & Troubleshooting] IT_Architect:
We used to be able to multi-boot and select the ROM we wanted from one of multiple ROM slots. I don't know the answer to that but that is what he is referring to.
[Android Q&A, Help & Troubleshooting] Revontheus:
Yes, I was around back when that was the fad. As I've mentioned, it has lost popularity because it is more challenging to implement such a setup, and the need to do so when the differences between custom ROMs remain minimal.

Case in point, this thread has barely gotten any attention since the time it was written. Clearly it hasn't been the most missed by most members here.

I think my device got banned by Snapchat for switching between accounts. I tried spoofing fingerprint and device model but don't work. I tried imei spoofing but it seems that the modules even they act normal, they don't actually change the imei. Any suggestions either a tested module that spoofs imei or another way? I'm not even sure that imei spoofing would work so if anyone has a suggestion..
[General Questions and Answers] Revontheus:
Verify if it's the device or your account that got banned. Try logging in on another device.
[General Questions and Answers] Aserar:
Yes I did verify that it's the device
[General Questions and Answers] xXx yYy:
What you can try:

Use a VPN or proxy server.

Snapchat bans devices based on their IP addresses, so you can try to bypass the ban by using a VPN or proxy server.

Change your phone's MAC address.

Each device has a unique MAC address that Snapchat can use to identify it. Take note that changing your device's MAC address on Android requires root access. You may use a root-enabled app such as ChangeMyMAC.

EDIT:

Android devices do not have the ability to directly modify the MAC address of their Wi-Fi adapters. This is because the MAC address is a hardware-based identifier and cannot be changed without modifying the device's firmware. But there is a workaround that can be used to simulate a different MAC address:

Use a virtual Wi-Fi adapter. A virtual Wi-Fi adapter is a software program that emulates a physical Wi-Fi adapter. These adapters can be configured with a different MAC address, which can then be used to connect to Wi-Fi networks.

So if your phone is rooted and you have knowledge of Android shell scripting then to periodically change device's MAC address you can create a script as this one

View attachment 6061406

and run it via a third-party app such as

SH Script Runner - Apps on Google Play

Bash script runner and shell command executor with superuser functionality.

play.google.com
[General Questions and Answers] Aserar:
Thank you for your response. Honestly my knowledge of android shell is executing commands and following instructions but it's an opportunity to research and learn a new thing. I tried the Change My MAC app but it didn't work. I'm not yet sure if this is bc Snapchat identifies the phone using something something than the MAC address or bc the app is not effective on A13.

How positive are you that Snapchat using MAC as an identifier? I did lots of tests to rule out everything that is not device related (ROM, network, IP, accounts, etc)

Hi any luck?
[General Questions and Answers] IT_Architect:
How can I prevent Verizon from changing my Samsung phone from U1 firmware to U with their carrier firmware? You buy an unlocked phone because you travel a lot. A firmware update comes along and the carrier forces a firmware update on you that installs all of their proprietary firmware automatically. There is no place in settings where that can be turned off. The area in settings to not automatically install updates only controls U1 firmware updates. If connected to Verizon or their pre-pay division, ViSion, you cannot prevent their update from taking over your phone. The only action that can prevent that that I have found is before it gets a chance to install their firmware update, add my not-currently-active Claro nano-SIM from Colombia to force dual-SIM. The instant I do that, the Verizon firmware update immediately disappears from notifications and is replaced by a notification that there is an update available, which is the Samsung U1 update, that I can then go into settings and tell it to go ahead and install it if I choose. This situation has existed since at least the Note 9 where I had to jump through many hoops in ODIN which I don't know if I can do anymore and would like a more elegant solutions if one exists.

Thanks!
[General Questions and Answers] xXx yYy:
To permanently prevent Verizon from changing your firmware, you need to root your phone and install a custom ROM.
[General Questions and Answers] IT_Architect:
That would definitely do it of course but then I couldn't use my Samsung phone for credit cards or use it for travel anymore because it would kill credit card apps and probably passport apps and future travel apps.

From a practical perspective that still leaves me with maintaining an expired nano-SIM and requiring ViSion/Verizon to use an eSIM slot, or use my ODIN hack method that works so well on the Note 9 to determine if it will work on the S24 Ultra.
[General Questions and Answers] IT_Architect:
Here is something I noticed with the new phones that was not the same as my Note 9 on 8.1:

1. I can leave my foreign/CLARO nano-SIM in and active along with my active Verizon/ViSion SIM and it will remain U1.

2. If I simply disable the the CLARO nano-SIM, it will immediately tell me I need to reboot with no options to change anything and configure itself for Verizon U.

3. If you then re-enable the CLARO nano-SIM it will again force you to reboot to re-configure itself back to U1. There will be no Verizon apps.

*Thoughts: This is not nearly the mess it used to be. My thoughts are to make the Samsung apps the defaults, then enable the Verizon/Vision, which hopefully makes it so nothing changes in userland between domestic and foreign. Why would I want to disable the expired CLARO SIM? So it doesn't waste battery trying to find it.

I'll update this for the benefit of others as I learn more.
[Vivo X90 Pro Plus] Paulalikestech:
I'm looking for good screen protectors for the device, especially tempered glass ones if possible.

I also have another question, do tempered glass screen protectors stop the fingerprint scanner from working well? I've heard ultrasonic sensors struggle a lot more than optical ones...
[Vivo X90 Pro Plus] virtualknowledge:
Do not use tempered glass. I've been dealing with curved displays nearly 8 years and tempered glasses never ends up well.

Why? Because they curved edges are always the weakest point and even if u use a good case with elevated edges, the chance of it being broken is quite high and follows up the rest of the display. Does it protect? Yes. But in the long term and not a cheap option..

Also producers are not making a fully glued curved tempered glass due to the QC issues that the glass doesn't sit fully in the edges. That leaves you with tempered glasses to be applied with uv glue which is a pita process. Installing it without remaining bubbles is wo damn tricky even though you follow the instructions. Also if it goes bad, good luck dealing with the cleaning of that ****ty uv glue.

Let's say you managed to install with uv glue. Nice. Then there's a chance that the glue will lose its tight integrity in the edges in time leaving the space between glass and display making it more fragile. Let's say it broke and you want to remove it. There's also very high chance that you'll remove the glass but the uv glue will be stuck on the display. Good luck removing that sht without scratching your display.

Despite above there are tempered glasses that stick only around the edges and fingerprint area that barely read your fingerprint. There are also ridiculous tempered glasses that has a hole in the middle of the glass for fingerprint as they su.k at transferring ultrasonic waves so they leave that part empty.

Long story short use film. They don't protect as good as glasses but using the phone with a good case elevated around the display edges, protects it enough.

Don't use hydrogel ones, they're easy to apply, seems nice at first glance but very soft and you can easily leave marks on it by pressing with the nails.

I use the following. Idk how many times I ordered. After applying, you use uv light to harden the sticky material. That makes it harder than regular hydrogen films. Even I'd say it's like the original that comes with the device.

https://a.aliexpress.com/_EItCccN

I see some idiots ordered it without knowing how to apply. One said no camera hole. Why hole needed genius... One said uv light doesn't work. Well it's tricky to make them work but they work. If you follow up the installation smoothly it sits so damn well.
[Vivo X90 Pro Plus] Paullebricoleur:
Thanks for the answer!! I'm happy to have feedback from someone actively experiencing it first-hand. I assume the fingerprint sensor works perfectly fine even with the film you're using? (Don't mind the different account, I just managed to find the password for my main one)
[Vivo X90 Pro Plus] virtualknowledge:
It works perfectly fine. I have used about 6-7 of them so far. I change after the oleophobic coating wears out amd there are enough scratches to piss me. If you're not a heavy user like me, it should last even longer for you. :)
[Vivo X90 Pro Plus] Paullebricoleur:
I'm glad to hear it works fine! Last question since I forgot to ask-, how is it to the touch? I've hada few plastic screen protectors that really felt pretty ****ty to use so I'm a bit worried about that also...

Thanks for the link also! Finding direct recommendations is hard
[Vivo X90 Pro Plus] virtualknowledge:
I'd say it's pretty much close to the one that comes on the phone after installed in the factory.

Because uv light hardens the sticky layer under, it becomes harder like slightly glassy. Very similar to the foldable phone's big screen. I used to hydrogel ones but they're softer.
[Vivo X90 Pro Plus] andrejd1:
I have this. It worked best for me. It is basically like a stock screen protector. No issues with fingerprint reader.
[Vivo X90 Pro Plus] Bl3s:
Andrejd1 and virtualknowledge - do screen protectors you recommend cover curved sides of the screen as well? I got one 'ceramic' from aliexpress but I'm reluctant to try it so I still use the stock one, but if you say these films are good I'm gonna get one in case the 'ceramic' does not prove to be worthy.
[Vivo X90 Pro Plus] virtualknowledge:
It covers of course.

I don't recommend the hydrogel soft ones.

Smb might purchase both and try.

[Galaxy S 4 Mini Q&A, Help & Troubleshooting] steve8x8:
Can you connect it in normal mode (with Android running, and Developer mode activated / ADB allowed)?

Try to use a USB2.0 hub between your computer and the phone
[Galaxy S 4 Mini Q&A, Help & Troubleshooting] Kalupyamusa:
Hi. I happen to have the same device. Hopefully this work around works. I rooted mine using Kingroot apk. Before you start the root process unlock developer mode by tapping on the build number several times in settings.

Connect your device to WiFi, open king root and tap root. If it fails the first time try again. Once rooted use a Firefox browser compatible with 4.4.2 as its the only one that supports a lot more updated sites on that Android version. Use it to download TWRP from official site and install it. Run it with root and restart your device.

You should now have TWRP recovery installed. Head back to forum once device rebooted, open Firefox, navigate to supported thread for S4 mini custom ROM and download Lineage OS zip and Gapps zip.

Flash them both using TWRP. Make sure to follow provided steps on forum.

once new ROM installed and wish to root the device again.

Installing Magisk

Download magisk.apk from official site but don't install.

Reboot into TWRP recovery and flash the magisk.apk file.

Once done, reboot to system.

Then install the magisk.apk from file manager. It should prompt as an update.

Open once installed. It should prompt that magisk is not properly installed so follow simple step on setup. Please do not dismiss prompt on setup.

Once magisk flashes magisk, reboot Device, install root checker and device should be rooted successfully

Hi all I've just installed package disabler pro and on the app it says root yes I hope I haven't tripped knox I've taken a picture in download mode and help please thanks
[Samsung Galaxy S24 Ultra] Rapier:
You're safe, a tripped Knox will show Waranty void: 0x1 yours say 0x0

Also there's no way you could root the phone and trip Knox just by installing an app. The fact it says "root" either means root is required for it to function properly or some of it's functions need it.
[Samsung Galaxy S24 Ultra] brockyneo:
OK great thanks for your help I'm assuming I cannot trip knox unless I unlock the bootloader which I will never do lol

[Samsung Galaxy S24 Ultra] aslg:
I just unboxed my S24 Ultra Titanium Gray, and I noticed light scratches on the left side and the top of the titanium frame (see pictures). They are visible only if the light hits the frame at a certain specific angle. Is this a common problem?

I have doubts whether asking a replacement or not. Could I get a worse one?

I remember there was a plastic film around the frame of the S23 Ultra to protect it during the shipment. There was none for my S24 Ultra.
[Samsung Galaxy S24 Ultra] Rapier:
Can't really tell due to the reflecting light in the photo but is that the "black" color (that is actually a dark/graphite gray)? It looks like it is scratched, I checked now on my Titanium Violet (that has the light frame color) and doesn't have the slightest scratch or sign. I would ask for a replacement if I were you...considering it's price, should be perfect (at least when it's new)
[Samsung Galaxy S24 Ultra] Craig_D:
It may only be "scratches", seen only in certain light, but, if you did request a replacement, how much worse could it be? For the amount of money you're paying I think that's terrible! I'd definitely be sending that back if mine arrived like that in a few days!
[Samsung Galaxy S24 Ultra] aslg:
It is the Titanium Gray color. The frame is also gray.
[Samsung Galaxy S24 Ultra] Rapier:
The frame is like mine then...and I have no scratch on it after almost a week of using it without a case. Send it for replacement of if that is not possible you could return it. Thing is, preorder is ending soon, only 2 days left and the double storage deal is better.

I remember there were some "pencils" on Amazon or AliExpress to remove scratches and they did a good job on metal, especially on brushed one like this titanium frame. If you can't get a replacement maybe you could try one of those or with a very mild polish paste. But if it doesn't bother you so much, I'll leave it like this, probably you'll put a case on it anyways and won't be visible

MUST-READ BACKGROUND - "Light" vs. TD-based:

TD-based, as its name implies, is built upon the full TrebleDroid patchset, and has better compatibility with legacy devices, Samsung, etc.

"Light" includes much fewer patches that are known useful first and foremost for my own devices (and modern devices in general), so that I understand and maintain it slightly better. It's also my daily driver and test field.

For more background info, read respective sections of LOS20 "Light" and TD-based threads, where this differentiation started.

No flashing instructions will be offered. If you're here in this forum, you should know what you're doing.

No guarantees that everything would work. This is a GSI, bugs are bound to happen.

The selfish nature of the "Light" approach means I can and will ignore certain bugs as I see fit. Deal with it or kindly go try something else.
