[General Questions and Answers] Xerora:
I scoured the internet for the last few hours trying to determine if there is still a way to use an app, or some other method to essentially hotspot my phone, without a hotspot plan. My phone is network unlocked from OnePlus directly, and I have unlimited everything (not even cap throttling) through US Mobile, but they changed their hotspot services (afaik) after they moved to "WARP 5G." Last year I switched to them from Google Fi SPECIFICALLY because of the hotspot capability, and I don't want to start paying for it now, especially considering the Warp 5G capability is on their SUPER LTE (Verizon) specific sim, while I can only use their GSM (T-Mobile) sim.

I digress. Is there an app or ROM/Root method that will let me share my phones data with say, an iPad, or other phone? PDAnet and Foxfi only repeat whatever Wi-Fi signal my phone is connected to, and this is not what I'm looking for. (Woe 2012 3g pdanet)

Edit: it appears im a fool and just didnt figure out how to tether via BT to an ipad. In the mean time, if any of you have some decent ideas, im still all ears for if/when i need a back up plan

I noticed an unlocked US 3G Diamond at Best Buy today. I'm sure this has been asked before, but I can't seem to find the answer.

What makes the US version work on AT&T with 3G over the imported version? I have not seen a radio upgrade that allows it yet. The handsets actually looked quite similar with the exception of the back and battery.

I'm just curious whether to pick up the new one in order to get 3G service, or is there a radio update expected?

Thanks to anyone that can shed some light on it for me.
[Touch Diamond, MDA Compact IV ROM Development] mpf54:
I have a US 3G version and the freq. that at&t uses here has been enabled.
[Touch Diamond, MDA Compact IV ROM Development] The Juggler:
Sure, it would be the 850 and 1900 Bands. But there are Quad-Band radios available for the EU Diamond. I wonder if it's a question about the device not having specific hardware or just being able to enable those bands to work properly.
[Touch Diamond, MDA Compact IV ROM Development] calito:
Sorry for my english

he American Diamond has quad band in GSM and only two band in HSDPA, The people here says that is a har problem not the radio, the people put the american radio (08) in European version and dont work.

The American version came with the 1340 mh battery and without the front camera. Carlos

[Touch Diamond, MDA Compact IV ROM Development] Pumpiron579:
I have a Touch Diamond I bought last week from new Egg, just like the ones from best buy. For some reason, I can pick up the 3G signal and it will hold on to it for just a second, then x..{disconnects}..then immediatly picks up Edge and then Hsdpa?

I get 25% Edge and 75% Hdspa. I guess if you read the box, it says it picks up a 3.5G internet Broadband Connection....Anything over 3.5mbps is Hsdpa.
[Touch Diamond, MDA Compact IV ROM Development] The Juggler:
I notcied that the US version had the 1350 mAh battery instead of the 900 mAh like the EU version. Was there any documentation on why they did this? Has anyone checked if putting the smaller battery and slimmer back on the US version causes any problems?

I also find it odd that HTC briefly listed the Diamond as a Quad-Band phone on their website, and have since changed it back to a Tri-Band phone.
[Touch Diamond, MDA Compact IV ROM Development] charly_mx:
I still have hope that our European Diamond will work with US 3G with somefirm ware flash or something

Hey, I'm looking for a custom recovery for my phone which is NX669J.

I have to mention that it's a A/B partition phone.
[Samsung Galaxy S21 FE] kirbyNx:
Very good, you have successfully rooted your S21 FE device? any problem unlocking the bootloader like breaking the camera like Galaxy A52s?
[Samsung Galaxy S21 FE] Williamtung:
In fact, I don't own this device. I have heard the problem of A52s and S21 is Samsung's S series. It is known S series is top set. So, I don't think there will be problem like that. All Samsung devices can be rooted using this way. Only except USA locked Snapdragon model
[Samsung Galaxy S21 FE] Doghan13:
My S21 FE is rooted and camera still awesome. Don't know what you mean by broken but all I need is working like it should (pictures, vidéo, zoom, effects, pro...). To me, you can root without fear :)
[Samsung Galaxy S21 FE] Williamtung:
It’s great to hear that. Thanks for letting me know it works:)
[Samsung Galaxy S21 FE] kirbyNx:
Good to know, Galaxy A52s camera stops working when bootloader is opened.
[Samsung Galaxy S21 FE] Williamtung:
Fortunately, it doesn't happened with S21
[Samsung Galaxy S21 FE] wazer1337:
Is there any possible way to root temporary, and if so will it trigger knox? and if so can I untrigger knox again after root is removed?

I need to add some 2fa auth keys to an app which requires root since I got them backed up from my old phone.
[Samsung Galaxy S21 FE] Williamtung:
Once you have unlock your bootloader, you will trip knox forever
[Samsung Galaxy S21 FE] wazer1337:
I got eu version with snapdragon I got the possibility to unlock with OEM unlock via developer options. That would trigger knox?
[Samsung Galaxy S21 FE] Williamtung:
Once you have unlock your bootloader(unlock OEM unlock & unlock bootloader in download mode), you will trip knox forever
[Samsung Galaxy S21 FE] wazer1337:
I guess there will soon be some bypasses without the need to unlock bootloader?

Samsung allegedly hacked by the same group as NVIDIA, first data leaked - VideoCardz.com

Hacking group LAPSUS$ claims to have accessed Samsung confidential data Extortion group released a teaser with the first information exfiltrated from Samsung servers. The same hacking group that managed to infiltrate NVIDIA servers 2 weeks ago has now begun leaking Samsung confidential data...

videocardz.com

source code for every Trusted Applet (TA) installed in Samsung’s TrustZone environment used for sensitive operations (e.g. hardware cryptography, binary encryption, access control)

algorithms for all biometric unlock operations

bootloader source code for all recent Samsung devices

confidential source code from Qualcomm

source code for Samsung’s activation servers

full source code for technology used for authorizing and authenticating Samsung accounts, including APIs and services
[Samsung Galaxy S21 FE] Williamtung:
are you sure it is not spamming?
[Samsung Galaxy S21 FE] Badger50:
Let's put it this way, I certainly hope NOT!!

Cheers: Badger50 FSM
[Samsung Galaxy S21 FE] Williamtung:
So, is Samsung's bootloader really got "hacked"?
[Samsung Galaxy S21 FE] Badger50:
That remains to be seen. There was a lot of proprietary information released in this hack which could lead to what you stated. However, XDA wants nothing to do with this if it comes

to fruition since it was acquired by nefarious means.
[Samsung Galaxy S21 FE] Williamtung:
Thanks for your reply. I wish the bootloader business will be fixed soon by Samsung and no harm has been done. Also, UNLOCK ALL THE BOOTLOADER FOR ALL MODELS, SAMSUNG!
[Samsung Galaxy S21 FE] wazer1337:
Nobody can stop experience and know how when it comes to hacks and exploits, even if XDA does not want it here, you will never be able to stop the learning from it which will lead to exploits, which none of you can ban/deny because a) it will not include stolen gods b) you will never know how the exploit was obtained.

Don't forget XDA would never exist if it was not for expoits and hacks/mods from the community.
[Samsung Galaxy S21 FE] Williamtung:
Well, you are right. However, XDA will not allow the illegal stuff in it. Samsung confidential data, for instance
[Samsung Galaxy S21 FE] zeechia:
Thanks for this awesome resource btw. I have a S21 FE (sm-990B) (snapdragon 888 ver) European version. Its running on Android 11 and I want to update it to the Android 12. The problem is I am in South Africa and want Samsung Pay to work as well. Right now it says - no service provider set... when I run Samsung Pay. I see there is a firmware available for South Africa but with a sm-990E firmware (probably enynoss). https://www.sammobile.com/samsung/galaxy-s21-fe/firmware/SM-G990E/XFE/#SM-G990E

Question is can I flash this firmware on the sm-990B or can I try using the EUY version of the sm-990B firmware....

or what is your suggestion...

Thanks to whoever responds...
[Samsung Galaxy S21 FE] Williamtung:
You can flash the firmware of the same model definitely(SM-G990B) However, I don't suggest flashing the firmware of another model. Like what you have said, it is probably Exynos and you cannot flash it. If you are quite sure your model is simular to another model, you can use the patched Odin to flash the firmware
[Samsung Galaxy S21 FE] zeechia:
Thanks Will... nice to meet you. I am currently running the EUX version of the SM-990B, but the android 11 variant. What you suggest I flash the EUY or the EUX variant of android 12, to get samsung pay working. You see I am kinda of thinking that Samsung pay for android 12 may pick up that I am in South Africa and authorise the app. Probably won't but there is a possibility. However if I flash EUY, its could be closer to a global version, rather than the European Union version... all guessing but maybe someone here has tried this... bear in mind I don't want to void my current warentee...
[Samsung Galaxy S21 FE] OseiSB:
Is there any way to get the OEM Unlock option on the SM-G990U or is it just impossible?

Would flashing an SM-G990B firmware work since it's also snapdragon?
[Samsung Galaxy S21 FE] Williamtung:
There are no way to unlock the bootloader of the US model. I think the way they lock the bootloader is using two bootloaders. One of them permanently US model’s bootloader. Another one is firmware’s bootloader. I think they use this way to prevent users to unlock the bootloader.
[Samsung Galaxy S21 FE] joke19:
This don't work? fastboot oem unlock. I've 990b with the unlock option.
[Samsung Galaxy S21 FE] KlemenC:
How is this possible. S21 FE was released on Android 12 OneUI 4.0?
[Samsung Galaxy S21 FE] Williamtung:
I think you haven’t use Samsung device before. Samsung don’t have fastboot mode, you see. The only way to have fastboot is by the way of using some AOSP roms with proper fastboot support, like PHH’s
[Samsung Galaxy S21 FE] Williamtung:
Well, Samsung has released Android 12 for Galaxy S21 FE (for some model)

[Samsung Galaxy S21 FE] bigPAL:
I just installed Bifrost and Malwarebytes gave me a warning it contains a backdoor trojan called Backdoor.Bifrose? What the hell?

Edit: Probably a false positive due to name similarity.
[Samsung Galaxy S21 FE] ish4d0w123:
No. You can undo most of the process, including flashing back stock firmware and recovery, but you cannot revert bootloader to the factory locked state, relocked at best. They will know.

Yes, rooting WILL trip/blow the KNoX fuse. It doesn't "trigger knox" but the fuse itself.

NO. Once again, knox is not what you think. It is a complex system consisting of BOTH software and hardware components. Among many components, it has a physical FUSE inside the SoC (ie. the snapdragon or exynos chip) which will be tripped/blown once knox detects such an intrusion. There is absolutely no way to undo this, and there never will be, as such a trip operation physically changes ("damages") your chip. It of course doesn't damage it really but leave a permament mark and from that point on, warranty is void and many security features that depend on knox will not work. You can even see this change with a powerful microscope. (Just google it)

That is absolutely not worth it in my opinion. Just do it on an emulator or on an old phone and harvest the keys. Many 2FA auth gen apps now offer migration methods, and even if it doesn't, there is always a way.

But that is not rooting and ruining this beautiful phone just because you couldn't migrate your data in a different way. You can.

Just my opinion.
[Samsung Galaxy S21 FE] ish4d0w123:
NB. OEM unlock and bootloader unlocking are two very different things. Perhaps the first one is already done/not needed if you can't find it.

For unlocking bootloader see the first post.
[Samsung Galaxy S21 FE] quasimodoz:
Reading thru these posts I'm a little bit confused. All my previous Samsung phones were rooted, the last S7 without tripping Knox. Know I also want to have my S21FE rooted without killing Knox. The whole purpose is to have full access to all files, no special firmware etc.

Is there any way to establish that?
[Samsung Galaxy S21 FE] joke19:
I search for the answer, too. My is 990b Vodafone and want use eux or euy
[Samsung Galaxy S21 FE] kirbyNx:
If you root, install custom recovery or any unofficial samsung software you will break knox.
[Samsung Galaxy S21 FE] quasimodoz:
Earlier versions of Towelroot claimed to root Galaxy phones without tripping Knox. What about (current?) version 5?
[Samsung Galaxy S21 FE] ShaDisNX255:
Towelroot probably used an exploit that is probably patched in today's more current fw.

Unless someone can find an exploit, which I doubt, the only way to root will be to trip knox.
[Samsung Galaxy S21 FE] MemurBey:
Hi, thanks for post but I have a question.

good morning,

i want modding my phone just for recording all call by bluetooth samsung buds.

I have some questions:

1) before modding i have to reset phone and make a backup of all data and app?

2) I have installed also samsung pay, about security will remain same or is better to not use phone as credit card anymore?

3) I have Kaspersky antivirus, will protect phone as before and will work well also after modding?

4) I write from italy, the language after modding will remain italian?

5) My phone is still in warranty, after modding it is possible to go back on original software?

Many thanks in advance.

Kind regards

Hello everyone, I have s21 fe G990BXXU1CVC3 (SD 888) blocked by the operator. Can I somehow reflash it to unlock it? The phone cannot be used due to the lock. I also wanted to clarify, as I understand it, the bootloader on 888 cannot be unlocked and set the root accordingly, right?
[Samsung Galaxy S21 FE] RixTrix:
How do I identify this?

"USA locked Snapdragon model"

Is this locked to US or locked as in "all your phone are mine"
[Samsung Galaxy S21 FE] spamtrash:
Personally I do not think that you'd obtain any support there. Phone locked by operator (apart from the SIM lock preventing the phone from using other network providers, what can be easily bypassed by obtaining the code) is set on the device (e.g. IMEI lock) as result of not fully paid back phone credit or reported phone being stolen.

In both cases unlocking it would be illegal.

OK so after unlocking bootloader and getting root - you lost connection to Cameras on Samsung firmware!

Plus some of samsung apps using knox security don't work like Samsung Health which is using for Galaxy Wear smartwtches. (is bypass i know)

I don't recommend to doing for now this because i don't get to working camera app on rooted with magisk phone on samsung firmware, and any other GSI roms have more likely support for one main camera (on OpenCamera in GSI ultrawide works but like 1 time on 4 atteps )

Hi guys, I would like to know how you proceed ususally with OTA's. Is it possible to re-root without losing any data?
