S20 5G OneUI 4.0 Android 12 Beta Biometric Security Not Working - Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News

Updated yesterday my phone (S20 5G unlocked) to A12/OneUI 4 beta and fingerprint and face unlock no longer work. Deleting and re-adding fingerprints or face does not do anything. I'm on US unlocked, with Snapdragon 865.

While I don't have the answer for you, were you able to capture the S20 5G snapdragon link to download the beta?

Everything working fine with me.

Dónde descargar la versión beta o usó el banner para miembros de Samsung El hilo no está disponible Descargar Mi modelo es SM-G981U1

SGH I337M

Good morning guys, I have just bought a second-handed Samsung Galaxy S4 Today, and as I always do, I wanted to see the development for it, the problem is the model, there is almost nothing here about it (SHG I337M). I have never owned a Samsung smartphone so I ask someone here for help about it. You could tell me about KNOX, root, Custom ROMS, and stuff like that.:highfive:
Thanks for your attention, have a nice day!:good:
You can lock the phone down using KNOX. Or you can limit what apps one can access if the phone is in KNOX mode. So basically it is just some security stuff from Samsung. KNOX also has some warranty usage, but since the phone is second hand it's pointless.
So you can throw KNOX out the window.
The SGH-I337 is the AT&T version of the GT-I9505 model. So it's just a rebranded phone.
Unfortunately, AT&T like to lock the phone's bootloaders, making rooting and flashing custom recoveries a lot harder.
Not all hope is lost, though. You can still root and/or flash a custom recovery and rom, but it all depends on your firmware version.
You should definitely check your firmware version and then see if there are any ways to root it and flash a custom recovery. Then we talk custom roms.
If the phone is indeed an i337m (the att version does not have the "m" at the end), you are lucky because the bootloader is not locked and you are free to install twrp and customs ROMs based on cm, aosp, and tw.
You might want to check out the att forums for the s4 for ROMs too.

Thanks for your fast reply! As I saw down here, my phone can't be the at&t version because of the "m" and because it comes from the mexican carrier TELCEL. Respect to the firmware to be able to proceed with the root, recovery and that stuff... My S4's firmware could be here (I'm not sure about which of these data is)

The firmware doesn't matter anymore if it is an I337M.
The I337M is a Canadian model.
Now you can root your phone and install a custom recovery
Or
Install a custom recovery first and then flash a custom rom.
I suggest not trying a rom for the s4 with a exynos processor. I have read stories about owners of the Samsung s3 that hard bricked their phone by flashing a non-Qualcomm rom.

Hola, creo que eres de México. La mayor parte del desarrollo está aquí, casi todas las roms que son para el GT-i9505 también son compatibles para SGH-i337M ya que son muy parecidos en hardware. En estos foros está TWRP y si te gusta CM hay dos roms muy buenas Optimized CM 13 y Synergy's ROM.

Mine has Qualcomm's processor, does the GT-i9505 too? So I could install a ROM for that model on my SGH i337m?

I already told you that the I337M is a rebranded I9505.
The i9505 has a Qualcomm so it should be okay.

Sí, también. Si vas a hacer el root en la ROM stock, hazlo desde odin con este paquete https://download.chainfire.eu/811/CF-Root/CF-Auto-Root/CF-Auto-Root-jfltecan-jflteub-sghi337m.zip sino primero tendrías que instalar twrp para una ROM personalizada. Tiene el procesador de qualcomm justo como el i9505, así que no te preocupes
Yes, me too. If you want root on the stock ROM you need to flash this package through Odin, if not, you will need twrp for a custom ROM. It has the Qualcomm chip so don't worry

G900A neither 3g nor lte

Well my problem is the following:
i bought a s5 g900a, im from argentina, and i bought it second hand to a friend of mine, who bought it in usa (the frequencies of this phone are the same we use in argentina, so they're ok), the problem is i cannot get the mobile network to work, the sim works perfectly in other phones but not in this, i wonder what could i do, i tried *#*#4636#*#* change to lte, etc but wont work, the other problem is i cannot root the phone, i tried kingroot, kingoroot, towelroot, etc and none works to me, the android version is 4.4.2 plz give me a hand!!
Hey man just connect it to samsung kies and then just update it to 5.0 which is the latest version for the s5 in south America,
Other thing is just flash a custom recovery ans them proceed to install cm13 i get 2 days with full usage on that rom.

Samsung Pay not working (region locked?)

I recently bought an S10+ dual SIM model on Amazon and brought it back to South Africa.
I am now having problems getting Samsung Pay to work. Does someone know how Samsung Pay does a region check?
It says "Samsung Pay is Almost Here"
"You'll receive a notification when Samsung Pay becomes available on your phone"
Samsung Pay is available in South Africa and working on my Watch and on my Note 8 that I bought locally.
My CSC seems to be correct (as can be seen in the attached screenshots)
Any ideas?
I managed to get it working on my imported S10+
I had to get the apks from my local Note 8 on which spay was working fine, and then simply copied them over and installed them on my s10+.
Both the spay and the spayfw (samsung pay framework) apk needs to be installed.
Note that my csc already seemed to be correct, so that also needs to match I assume.

Lenovo Z6 Pro L78051 4g connection problems

Hi.
Sorry for my bad English, it's not my native language.
Ask for their help to know more about the 3G and 4G connection bands.
Buy a lenovo z6 pro, the 8gb / 128gb version, bring the bands B1, B3, B5 and B7. In my country (Mexico) the operators use the B2 and B4, but in some regions they are testing the B7. I decided to buy it because where I live my Xiaomi connects to the B7 but now that I have the Lenovo it seems as if it could only connect to the 3G. An operator (At & t) also uses the B5 for 4G but does not connect to it, only 3G.
There have also been many problems with the roms of the Lenovo team since they sell a version as global but it is not, it is only a hybrid version with deleted Chinese applications. Therefore it follows that there is no global version. I don't know if these problems have to do with connections.
Annex two images where I show the Xiaomi that connects to the B7 and what an application of the Lenovo tells me.

My phone is with CN 11.0.575 and parched with the ZaZz version (The .bat 00_flashrom.bat anywhere), i already have TWRP Recovery and now is rooted with Magisk. I CAN HELP WITH AL THE PROBLEMS OF YOUR SOFTWARE, But, now i want to install the ROW Secure 11.0.284 version, i cant, i dont know if is the version of my QFIL, the drivers, but the process just arribe to system_3.img and stay every time that ypu want. I dont know, but i want to try with that ROM. I just can with the CN 11.0.575 ROM, i areally want to try with ROW, im using QFIL 2.0.1.9 .
Hello
I have very similar problem in fact the same I believe
When I start or recieve a call my current 4G full signal strength connection drops immediately 3G and the signal strenght become very poor. On the other hand while surfing on the internet there is no quality drop.
I have run a diagnistic test to my sim card and I get an error. I hope you have any information about it.
I am currently using 11.0.325 ST Global ROW. But on official stock rom the situation was the same.
It seem you have the Volte option not activated.
Check in your setting or maybe not activated by your operator ( turkcell by your mcc)
But i cant read turkey , i let you check that.
It's not a band issu, because you have 4g before call.

I've got the same problem in Russia. If the 4g is strong enough, then, the incoming call is OK. If the 4g signal is poor, or there is 3G or 2G signal, then when I answer phone the other side does not hear me, because my phone's microphone doesn't work. The problem is in the proximity sensor. To solve the problem you need to use to install Truephone app, and switch off the pre-installed google phone. Truephone does not switch off the screen. Another solution is to install 575 CN firmware.
Hi. Do you have the VoLTE function active? You can see it with the menu on call (*#*#4636#*#*). What ROM are they using?
I am from Mexico and in the network provider I am only receiving H+ (It is 3G but faster). My problem is about the bands. Because if my previous cell phone connected to the
Band 7 in 4G, this does not.
And I haven't had the problems they mention. If I have little signal, the call fails me; but if I am with 3 or more signal intent stripes, it works perfectly. I have the ROM 11.0.325 ST

4g problems and sound
I also have problems with 4g connection (it always stays at two bars of H+, Vodafone network,EU), can anyone post a tutorial how to solve this ?!? Also the person I'm talking to WITHOUT headphones hears me really bad.
Device info:
Lenovo z6 pro
Miui 11.0.325
Unlocked, twrp recovery and magisk.
Change the global one it's useless.
Unlock bootloader and flash Zazza Rom Base on China 1.1.080. you'll no notifications problem.

Hello everyone.
I bought a chip that uses band 2 for 4G and I bring 2 chips. Since I have one of them when it warms up, an x ​​begins to appear in the signal and does not recover until I get into airplane mode or restart it. But the strangest thing is that when I play and the cell warms up, they both start to fail, as well as Wi-Fi, they turn off and turn on, until it appears to me in the bar as if I didn't have a SIM and the Wi-Fi also turns off. when I had a chip that never happened to me.
Do you have any idea why it is? And why when the cell phone heats up does that happen or will it be the other SIM Does anyone else happen to this?

I applied your solution it helped thank you. But it is not fully solved. I tried all roms ( official, Zaza version, global version) but the problem always exist. Can we fix this sensor or the problem is about the antenna?

Yes, we (4PDA Russian community) are close to solve it. We found that the problem is in EFS partition. That partition contains the info about all kinds of phone's networks and IMEI also, and we have an opinion that only 575 CN firmware is totally ok for the sensors and antennas. So it is a great idea, but it has not been tested yet. For the first you need to install 575 CN via QFIL, 2nd - to install TWRP, 3rd - to backup the EFS partition via TWRP. To save that backup on SD-card. Then install the global firmware (the latest 375, for example)? TWRP again to restore the EFS from backup. It has not been tested yet.

A515U and A515U1 Firmware Links and Flashing Discussion Here

For those who aren't already aware, A515U is the model number of all of the US carrier versions of the Galaxy A51. The A515U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100% interchangeable among these models (as it is with any U and U1 models): any U or U1 firmware version can be flashed to any U or U1 device at any time, assuming that you're not trying to downgrade the bootloader. Also, U firmware is identical for the 4 base files (AP, BL, CP, CSC) for each individual build, no matter which carrier it comes from. So if you download 2 different carrier versions of the exact same build, the 4 base files will be identical. Where the firmware differs is in the USERDATA file - that's where the carrier bloatware and customizations reside.
Manual Odin flashing is designed for those who:
- want to manually update to a newer version of U firmware on their U device, either because they don't want to wait for their carrier's OTA or because OTAs aren't working on their device, or a different carrier got a new feature/patch before they did
- want to flash U1 firmware to their U device
- want to convert from U1 firmware to carrier U firmware
- want to convert from one carrier's U firmware (with all apps and bloatware) to a different carrier's U firmware (with all apps and bloatware)
For those who aren't already aware, anyone can now download firmware for almost any Samsung device any time that they want, via SamFirm or Frija. There are threads and info about them here on XDA so I won't waste time explaining - do a search if you're not already familiar with these tools. But they only provide whatever the latest/newest/current version is - nothing older. I pay for a subscription to a site that gets the official releases (usually) before they hit SamFirm/Frija, so that's where my files come from. However, I don't have unlimited bandwidth on the site, and it's also quite time consuming to download the files, zip them up, and upload them to AFH. And, I do threads like this for every single Ax, Sx, and Note x model - so I won't be uploading every single version. The only full builds that I upload are ones where I get access to a new bootloader and/or Android version early, before they hit SamFirm/Frija. Also, since AT&T doesn't allow their firmware to be publicly available (for any of their devices), I'll try to always upload at least one USERDATA per bootloader increment for AT&T (and Cricket, if they get this model). I'll also upload any full builds if AT&T is the only carrier to get that specific build, because you won't be able to find the files anywhere else.
This is not a "beginner's guide to Odin flashing" -type post/thread, so I won't list basic, step-by-step flashing instructions. My threads are geared towards those who already know what they're doing. If you're new to manually flashing Samsung firmware, I recommend you consult one of those "beginner's" guides- there are tons of them here on XDA.
Happy flashing!
U firmware: https://www.androidfilehost.com/?w=files&flid=310014
U1 firmware: https://www.androidfilehost.com/?w=files&flid=310015
Notes:
- DON'T QUOTE THE OP WHEN YOU REPLY, kthx
- I have lots of threads just like this one for other Samsung devices (mostly the flagships), if that interests you. For those who have already made use of my previous threads for a different device and are upgrading or changing devices, welcome back
- My zips are compressed extra small for space and bandwidth savings. The default Windows extractor can't handle it, so you'll need a 3rd party tool like 7zip, WinRAR, etc
- My naming method for folders on AFH is: build - bootloader - Android version
So "SAT - 1 - 9.0" means the full build number ends in SAT, it's bootloader version 1, and it's Android 9.0. When bootloader and Android versions increment, the first build to have those changes will have its folder notated appropriately.
- Flashing the HOME CSC file keeps data intact; using the other CSC will wipe data. Flashing USERDATA will also wipe data
- For identifying USERDATAS, and to know what region/CSC to use if you're looking to get firmware from SamFirm/Frija:
AIO = Cricket (not available via SamFirm/Frija)
ATT = AT&T (not available via SamFirm/Frija)
BST = Boost Mobile
CCT = Xfinity Mobile (Comcast)
CHA = Spectrum Mobile (Charter)
SPR = Sprint
TMB = T-Mobile
TMK = Metro PCS
USC = US Cellular
VZW = Verizon (available via SamFirm/Frija, but Manual Entry is required - Auto will not work)
XAA = U1 firmware
- As some or most of you may know, starting with the S8, Samsung has included a feature in U firmware where it automatically changes the bloatware to match the SIM card of the carrier that you insert. So that means that if you have an AT&T device that's been SIM unlocked, and you insert a SIM from T-Mobile, you'll get a popup message prompting you to restart to apply new carrier settings. After the phone reboots from doing that, it will have converted itself to look like a model that was originally sold by T-Mobile, complete with all of their apps and bloatware. If you insert a SIM from a carrier that does not have its own firmware (a prepaid MVNO for example), then the phone might adopt the bloatware of the network whose towers the SIM runs on, or it might just keep the existing bloatware and not change it at all.
If you do not get that popup prompt when inserting a different SIM, and want/need to do the conversion manually, the correct procedure for switching from one carrier's U firmware (with all bloatware and apps) to another carrier's U firmware is:
1. Flash full U1 firmware package including non HOME CSC
2. Upon boot, insert a SIM of the carrier whose firmware you want
3. Watch for the popup that says "reboot to apply new carrier settings" etc, and do it
4. After that restart completes, reboot back to Download mode and flash the full U firmware package, with the USERDATA file of the carrier whose firmware you want
1. As of today's date, neither U nor U1 firmware appears to be live on SamFirm/Frija. Once I notice that it is live, I'll post about it (unless someone else beats me to it)
2. This is the latest patched Odin which will probably be required for flashing files - https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
I do not have an A51 and probably never will - I'm only providing the files for the benefit and use of XDA users. So I don't have any personal experience with this particular model

1. It's not called "jailbreaking", it's called "flashing".
2. You need to make sure you're using Patched Odin 3.14

You will never have that option under Developer Settings, no matter what you flash. USA models are not capable of having the bootloader unlocked

Nope. That's how all U and U1 models have been, ever since the S8

You think that flashing a file designed for a model that came out 4 years ago will work on this model?
HAHAHAHAHAHAHAHA
Im sorry for my ignorance i thought maybe something similar could be done
**CONFIRM Root Option**
So far I've found one site that claims to offer a root option for A515U:
//androidbiits.com/root-sprint-samsung-galaxy-a51-sm-a515u-easily/
I'm new and the forum won't allow me to officially post a link until after 10 posts so to visit the site add the HyperTextTransferProtocol (http) before the domain above
Has anyone been able to successfully try or implement this? For me the steps aren't totally clear.

"if you have managed to unlock the bootloader" - and I guarantee that you haven't managed that, nor is there any way to do that at this time. There are 1000 similar sites out there, all written in poor English and all claiming that you can root this device and that device - IF the bootloader is unlocked. All they do is copy/paste and edit the model number when a new model comes out and create a new page, all trying to get clicks - or something
Samsung galaxy a 51 bloqué sur écran de démarrage malgré flash
Bonjour à tous et à toutes,:cow-boy:
j'ai un samsung a51 non flashéet depuis jeudi dernier l'écran s'est bloqué pendant que je jouais à un jeu. J'ai alors éteint le téléphone et lorsque j'ai tenté de le rallumer, il s' est bloqué sur l'écran de démarrage où il est écris samsung galaxy a51 et ne veut pas aller plus loin. J'ai tenté de hard reset et j'ai remis les valeurs d'usines mais rien n'y fait. j'ai téléchargé la dernière version de ROM officielle Samsung pour le flasher avec la dernière version de odin3.14.4 et les derniers drivers usb samsung. L'installation s 'est faite mais toujours le même problème. le téléphone bloque au redémarrage sur l'écran samsung galaxy a51. J'ai remarqué que lorsque je passe en mode download il y a les informations suivantes :
product name : SM-A515F

KG STATE : Prenormal
FRP LOCK : ON
OEW LOCK : ON(L)

J'ai vue plusieurs tutos dans lesquels on flashait des samsung a51 et lorsque les personnes passent en mode download, il n'y a pas autant de messages écrits. S'il vous plaît aidez moi car cela fait déjà 1 semaine que j'essaie mais je n'y comprend rien je débute..
Merci infiniment de vos réponses. :doigts croisés: :doigts croisés:
Anyone know if this firmware is the same for the 5G version of the A51? ???
