Question A52 5G Factory Restore Fail - Samsung Galaxy A52 5G

I upgraded from the A52 5G to the A53, and months later I decided I'd restore my A52 and give it to my kid. Problem. I had a swipe pattern I don't remember, and I had created a generic Google Play account as I always do per device. I did a factory restore but somehow it still wants the swipe pattern to setup the phone again.
How can I fully wipe and restore the device so it no longer needs the pattern?

Remove your device from trusted devices in the mentioned google account and try again.
If this method doesn't work, try re-flashing your device using Odin.

Where do I find the files I'll need to use Odin for the A52 5G?

More specifically, where do I find firmware for a US unlocked version that I'd like to use on AT&T. I can't see to find the right CSC...I believe it should be ATT or XMS. Will any US CSC work?

SM-S327VL Galaxy J3 Luna Pro Frp Bypass?

I got this phone from a friend who also got it from a friend and its FRP locked. I have ODIN and I have not been able to find any firmware for this device. I seen some paid for but it looks risky. Any details on that? I would take it to stores but they will do nothing except a select few that I'm not trying to venture to. Obviously this is newer OS and stuff so I think it may require a bit more than just firmware, I keep hearing about some bootfile that looks different than the .md5 file or whatever it was... any help? Ive been able to get a quick settings app on it and i can get into settings but not developer options, I can't seem to disable google play services to bypass it, no successful root apps, running android marshmallow ?????

Hi bro.
Sorry to hear about the problem. I know the hassles of getting phones from someone else. You're not to clear on your problem. I assume you cant get into settings and therefor you had to download a 3rd party quick settings app. If possible go to settings and then "About". Look for "Software Info". There tap on the build number until you see a notification stating you are now a developer. Go back to main settings screen and developer options should be listed at the bottom. In developer options there should be an option for "OEM Unlock", turn it on and tr flashing again. If this is not possible try searching the settings for "Re-Activation Lock" and turn it off. Insert your password when promted and try again. If all this is not possible or fails then try Samsung Tool Pro. I cant post the link but just google D3X Samsung Tool Pro with loader. This tool is helpful for unlocking and bypassing FRP as well as flashing firmware, recovery's etc.
Feel free to ask for help
I used Nova for a forced launched homescreen and got into the settings that isn't the hard part. The hard part is the OEM Unlock. Been trying that build number a million times hoping something would do different and no sucess. I already have ODIN and Pro Tools but even they don't have the SM-S327VL firmware to fix this. I was thinking about re-partitioning it with odin... I know it's risky but if I brick it I would have to wait for the firmware anyway?. I cant flash a thing without any firmware. So far I haven't been able to find it on the samsung website or any others. I seen some that wanted money for them but I don't trust it. Can anyone confirm any? HhEeLlPp???
Finally disabled all google apps but I can't get rid of Knox
Frp bypass
I unlocked my phone on my own. I used an app called Test DCP and it became a device owner and then I restarted my phone and it was done. Good app????

Chinese Verizon s6e+(sm-g928v) with different firmware(of (sm-g928f))?

I know this phone is very old at this point. But my mom has been using this Verizon s6e+ that was bought from china (not from a official retail store) and it works on other operators! In fact, the phone itself doesn't recognize that it is a Verizon model. The about phone section says that the model number is SM-G928F, so I believed it had a ported firmware(!) and didn't give much thought into it. I didn't know Verizon phones are extra secured until 2 days ago. She upgraded to a s9+ and so I started searching for roms for this phone. I found a TWRP for the sm-928f, and tried to flash it with Odin, but that's when I git confused - the phone still has a locked bootloader. In Odin Download mode, it even says the phone model is SM-G928V.
As far as my understanding goes, it means that the Chinese folks have managed to bypass the Verizon lock, kept the bootloader intact, and installed a unlocked international firmware?
I came here to find someone more experienced on these to work on this case, i can confirm the following:
- Factory reset from phone settings reverts the phone to a new g928f; haven't tried wiping from recovery.
- most of Samsung/Verizon bloats are uninstallable just normally, but they appear again after a factory reset.
- the phone is stuck at Android 6.0.1 with TouchWiz and tapping software update from settings does nothing
Any devs interested in this case? Can this device potentially give us the solution to rooting Verizon phones?

an newbie need your advice and help!

hi all,
I have Samsung SM-G935W8 (in Canada), bought used from someone. recently, try to play with android, and realized the phone PDA was G935UUEU4BRD1, and model was SM-G935U which is different from the model that showing on back cover. think the guy flashed a different rom for this phone.
couple days ago, I did hard factory reset for no reason, and get google account locked. then search online and learning how to fix it. seems like need to flash combination rom --> use tool bypass frp --> flash official rom to solve this issues.
i downloaded many combination firmware and all failed on odin flash. until i use one that allowed me to flash and success to open the phone as Factory Binary. But, I noticed the phone model changed to SM-G935A, which is AT&T firmware. the android version is 6.0.1, when I try to run program to do FRP bypass, no luck, think that because I can't turn on OEM- Unlock option(can't find it on developer option tough)? or bootloader locked?
now, I can only flash official rom that from AT&T, and android 8 that I can find it. if the phone can be fixed FRP issues, model change to G935A is fine, I dont care that model, I dont use the phone for call, only for wifi and camera. and maybe later can play flash to other model of ROM. not sure if possible.
current, the working combination rom I flashed is PDA : G935UUCUBATA1
ADB FRP to bypass FRP (not working)
and flashed to AT&T rom PDA: G935AUCUBCTB1_G935AATTBCTB1_8.0.0
FRP still not bypassed, and stuck on google account validation screen. any advice how and what tools can bypass FRP for this phone now model is SM-G935A? thanks in advance!

Tab S6: Factory Reset with Stock ROM and still getting "protected by Knox Cloud Service"

Recently purchased a used Galaxy Tab S6. I was warned it had a warning about the bootloader being unlocked. No big deal. The seller couldn't remember his Samsung account credentials so we couldn't factory reset at time of purchase via Settings. No big deal. I went into Download Mode and relocked the bootloader. I went into Recovery Mode and Factory Reset.
Then I ran into "This tablet is protected by Know Cloud Service. To continue setup, connect to a wi-fi or mobile network." I've done that (since I can't skip the step) and get the dreaded "Can't create work profile" error and that's as far as the set up will go.
So I used Odin to flash the latest stock ROM and factory reset again and wiped the cache and I'm still having that problem.
In download mode, I've confirmed that Knox has been tripped.
I've googled like mad and I'm not finding a solution. Can anyone help me out? I'd prefer to stay on Stock ROM so there are no hardware issues (particularly with the SPen) as I'm planning to use this device extensively for note-taking (with OneNote). However, I'm open to custom ROM if that's my best/easiest/simplest route.
Thanks in advance!
If you're able, unlock the bootloader again. When you flashed with Odin, did you use the CSC or HOME_CSC file?

I used CSC. As I understand it, that is the "deeper" reset option.

Correct, that wipes user data.
Unlock the bootloader again, which will wipe the device (again), and see if it's removed the FRP. If not, you should be able to flash TWRP, from which you should be able to flash this to disable the FRP.
I can't access the developer options because I can't get through the setup wizard. So I can't flip the OEM Unlocking so the download mode doesn't give me the option to unlock. I can connect to ADB via the Recovery Mode but Fastboot doesn't see it so I can't do "oem unlock." Are there any other methods to unlock it? My friend Google hasn't found any yet.
Seller was able to login to both his Google and Samsung accounts and remove the device from them. That got me through the 100% Know Enrollment Service before it hung up in the "update" portion again. He was also able to send a message to the tablet from the Samsung account to try and release it further but, of course, since I've wiped it, that message can't get through.
I'm getting desperate. I might have bought a paperweight! Any once else have a suggestion?
Checked with the seller. He bought it from Kijiji as well from the original owner. It's always been a personal device, never an institutional one.
Last night's searching of the internet determined that the device is in "prenormal" status so I'm just going to wait 7 days and reboot. That might be sufficient. Nothing to lose at this point.

Question Sm-t227u mdm lock/rooting help

Hello! So I am on a journey to attempt to root a Samsung tab a7 lite sm-t227u. So I want to be extremely transparent as to my reason for rooting:
I was given this tablet by my father whom got it from a previous job. When he left the job they never asked for it back, a long with a good bit of supplies he had that he got to keep.
So, I have this tablet, I can get into it as it doesn't have a passcode. I have wiped it by factory reset as well. However, it has IBM's MAAS360 installed and after factory reset AND a firmware flash using odin I still cannot get rid of this maas360 mdm. It is not Knox locked. I can activate developer mode and change all those settings, but I cannot download any apps through the app store at all or enable unknown source app install as those are under an IT block. I also do not have the OEM unlock option in dev options. I've tried the whole changing the date and connecting to wifi, with and without sim card but I cannot get this option to show, nor can I unlock the bootload through fastboot.
I have read that most of the new samsung phones do not have a bootloader unlock option, but from what I can tell that is specific to the snapdragon phones, and this tablet is running a mediatek chip.
Now, if I can remove mdm restrictions without rooting that's great, but I have a feeling that is the only way to properly flash this thing to completely remove the mdm.
I have tried the recovery tar that is posted in this forum but I cannot get it to flash, likely because I still don't have an unlocked bootloader
Have any of you all faced something similar or know of a solution? I may call the company the mdm is managed by and just see if they will remove it from their system, but I find it highly unlikely.
SM-T227U is an American model wich doesn't have the OEM unlocking option, you could unlock using unofficial ways but those are not pretty "stable".

Hey man! Still got your tab 7? I also have a SM-T227U and have oem unlocked! After doing the usual stuff, you will want to turn off automatically update in developer settings. After that, go to settings>General management>Date and time and select manual time and date, and set it for exactly 10 days before the day you attempt this. OEM unlock will appear in dev settings!!!
Then turn off device and while holding power up + power down, plug into PC. It will show the pre-download mode screen where it asks if you want to continue. Just follow the on screen instructions to unlock bootloader!
*note that the bootloader unlocking results in an unavoidable factory reset**

Sweet! I will absolutely try this when I get home this afternoon, will report back with results!
But just for clarity. Let's say I start with a freshly wiped tablet. Go through set up and connect to wifi, do I need to add a Google and Samsung account? Then in dev settings, enable USB debugging, also enable wifi debugging? Then change the date. Is there any step I am missing?

If it has Mediatek chipset then you can use SP flash tool to format the tablet firmware and reflash it.
I would strongly recommend you to backup the NV DATA and NVRAM files before you format the tablet.

You can follow this guide actually! ( https://forum.xda-developers.com/t/...220-t225-install-lsposed-magisk-mods.4406933/) it recommends just skipping the setup junk
I have found that many times, rooting methods work across different models of the same device unless there are some sort of major differences in chipsets or some sort of random change lol
The only thing that doesn't seem to work for our model is section V of the guide which is for the removal of the "bootloader is unlocked" screen at startup. so you will still need to press the power button on that screen to boot up. It's a tiny hassle, but otherwise no big deal in my personal opinion
Make sure to read all the way to the end of the root section (section 4) and especially remember step 7. I retried probably 4 times and even patched the entire AP file of the firmware for use in odin (doing this gives a second warning on Knox screen that it isn't samsung official fw then boots normally into the bootlogo screen) before realizing everything was going fine.. I recommend just using the patched Magisk boot.img first just because I find it unsightly
Just flash the boot.tar in the AP slot. Don't download any of the boot imgs from the guide because they are for the t220's and t225's. I'll link the one I made according to the guide below. It'll save you some time and you won't need to install zarchiver and Magick just to have it factory reset again lol. Just download the latest Magisk apk (26.1) from the official github (https://github.com/topjohnwu/Magisk/releases) and install it when you have completed the 2nd factory reset/the patched boot img install.
