i messed up my a50 badly and now i cant get out of the download mode. - Samsung Galaxy A50s Guides, News, & Discussion

hey
i assumed the process of rooting and getting magisk was the same for the a50 as it is for my old a3 2016. i didnt even research to make sure the process is the same.. so i downloaded the a50 version for twrp, used odin, pressed on AP and just selected on the recovery.tar.md5 and started it. everything went fine until i tried to restart the phone. it keeps coming back to the download mode screen with some errors in red.
what can i do to fix this?

let's try it

Just flash the ROM to make it works again...

you have RMM Prenormal Mode. thats normal cuz the vaultkeeper mess it up.
connect both your device and pc, hold volume up and down and flash stock rom.
to solve the rmm, use my trick for this: check your update.
when it start to download, press stop and you can use it normal.

Phone wont start up, has anyone had this problem?

So I decided to flash a rom. I haven't done so on this galaxy s6 edge. I've always done it on my previous galaxy phones. The phone already had all the pre-reqs for EXTREME SYNDICATE. Once the phone rebooted to download, I used odin to push out the new OE2 FLASH ME. After that was done the phone just went into a boot loop. I double checked and made sure all the files were correct.
Now I am at a point where even using odin with stock image just goes to samsung splash screen and song then just gives me a Startup Failed - Please connect verizon repair etc.
Is there anything I can do on my end or am I screwed with this phone now. I can still go to download mode and the recovery mode that lets me wipe, reboot etc. But nothing seems to work. Unless I am missing something here.
All help is appreciated, thanks!
Mods can close this thread. I tried everything. Eventually flashing different OE2 and OF1 finally got it working even though I flashed the stock ....

Sprint Note 5 Boot-looping trouble!?

This is my first post and I'm in need of some help that I can't seem to find anywhere when searching the internet. I'm not a developer nor am I close lol I just have tons of fun learning the development process - it's seriously one of my favorite things to do. Anyways I've messed up royally with my Galaxy Note 5 N910P and I'm stumped on what I should do next! So here's the issue: My Note 5 will not stop boot looping!!! I've flashed stock, almost every version that I'm able to and nothing has worked. The last thing I remember doing before it started this b.s is rooting with CF Auto root. I've always used twrp then flashed Supersu and the dm verity and never had issue! But after flashing the CF Auto root I kept getting kernel is not seandroid enforcing and then the dreadful boot loop issue that has been going on for three days now! Is there something i'm missing? or not doing right? Please message me and let me know, and if this is the wrong place to post about this, I dont mind if my post is taken down just at least help with my question some how! Thank you, XDA is my favorite place - you guys are awesome, I don't trust any other source!!!

First of all you have entered wrong model no here note 5 model no should be SM-N920xx
1)Have you enabled Oem unlocking from developers option before flashing twrp and cf-autoroot using odin? If not then you done a mistake!!
2) Have you tried to flash latest stock firmware using odin with latest usb drivers installed on you pc and proper odin flashing guide?(Flash latest 6.0.1 for your device with latest usb drivers installed on pc and connect phone to main usb port using original usb cable) After flashing stock rom if your facing bootloop then you can try reset through stock recovery (Press volume down+power button to switch off your phone..When screen shuts off immediately press volume up+power+home key simultaneously untill you see Samsung galaxy note 5 logo, release keys..You are now in stock recovery from there choose wipe data/factory reset..After reset complete reboot your device)
3)If you can boot into twrp recovery normally then flash any custom rom suitable for your device i.e. for sm-n920p..Custom roms are pre-rooted so no need to flash cf-autoroot..Flash custom rom, if you successfully boot up the rom( It's difficult to boot custom rom though if you haven't enabled oem unlocking you will face custom binary is blocked by frp protection),then enable oem unlocking from developers option and try flashing stock rom again
4) Next option for you is download Samsung smart switch for pc, install latest usb drivers on your pc, connect your phone to pc in download mode(Press volume down+power+home button simultaneously),in smartswitch select emergency software recovery, it will ask you imei,model no and serial no which you can find either on box or back panel of your phone,smartswitch will detect latest stock firmware for your device, hit update now,give some time until update complete..Your device will be automatically reboot..If even you face bootlopp, then goto stock recovery(Press volume down+power button to switch off your phone..When screen shuts off immediately press volume up+power+home key simultaneously untill you see Samsung galaxy note 5 logo, release keys..You are now in stock recovery from there choose wipe data/factory reset..After reset complete reboot your device)
**IF SUGGESTION IN SECOND POST HELPS YOU THEN ITS DONE, AVOID NEXT SUGGESTIONS**
Are you sure you can't install cf auto root again to solve it? IF not...
I did a search and got hits for twrp for N910P. Get it loaded, get it wiped and have another shot at success. Next way to get rid of the persistent rooter gone rogue, load up a factory BL + AP. If that doesn't work download another version and try again.
I've enabled OEM unlocking, flashed latest stock AP...BL.. And so on, factory reset in both factory and TWRP. I have also tried flashing CF Auto root again to see if that would fix it also custom ROMs bootloop except for CM13 and Lineage OS- Which is weird because the ROMs are for the SM N920C model and I'm and Sprint model, So I don't understand that. Weird!! Everything recognizes me as SM N920C except when I am in download mode. Also, having no imei or any back ups make its even harder since my computer completely crashed on me because I am unable to use Samsung smart switch due to the wrong model and null imei. So I'm completely stumped with this issue. Not sure if its a corrupted partition or folders not being in the correct folder locations along with wrong permissions, I've literally stressed everything to my knowledge about this and I'm all out of what issues this could be related to

"Bricked" Note 8, can't boot into TWRP

So I tried to mod my phone (with this, if you're interested https://forum.xda-developers.com/gal...creen-t3759567) but I did something stupid. I thought TWRP was working properly but I'd installed Oreo and didn't wipe data. Well I installed the zip anyway. At the end, an error showed up (could not mount /data or something similar) and my phone will now not boot.
If I try to boot the phone, it just vibrates and stays black. Volume Down + Power + Bixby gets the phone out of this state and the charging screen shows again. I can't boot into TWRP at all. I can boot into download mode but Odin keeps failing when I try to reflash the XEF Oreo firmware (screenshot is in the attachment, it says passed but doesn't attempt to flash the files). I managed to flash TWRP which worked but since I can't boot into it it didn't help. Anthing else I can flash with Odin, or can anybody tell me what's going on / if it's unrecoverable? (I've tried a couple of different versions, they all exhibit the same behaviour)

There is a newer version of odin, are you using that? You will need that to flash Oreo. Can get it in the link below. Odin v3.13.1

Doh! Had it already, was the only one I didn't try. It's flashing now. Many thanks

How to recover from Verification Failed, Bootloops, and Android/Carrier logo freeze.

In this tutorial I will inform you on three different soft bricks, and how to fix them.
You must be able to boot into TWRP and/or Odin/Download mode!​
1.) Verification Failed.
Method #1
This method will work with people whom can't reset their device, due to an unmountable /data partition, and those whom experience this error, who can reset but have valuable items, applications, videos, or photos that they don't want to lose. Must be able to boot into Odin/Download mode. (Volume Down+Home+Power)
The solution is actually pretty simple. Boot into Odin/Download mode. This has to be done correctly, not from TWRP recovery. When the prompt for "Volume Up = Continue" and "Volume Down = Cancel (Restart)" press volume down. You should no longer see verification failed, but instead be sitting on the T-Mobile logo. This is normal, and could take 30 seconds to 10 minutes, depending on the amount of data.
This method works all because of Knox. Knox is what Samsung uses to void your warranty. Companies are not allowed to void a warranty when rooting, installing roms, or recovery, unless they have direct evidence. Knox will trigger this when it isn't sure. It will try forcing you to bring it to Samsung, and they can directly find out why it was caused. This happens when it thinks that you cancelled.
Method #2
This one will require you to lose all your data, but is mainly intended for those whom cannot reset their device. Download the stock firmware from the links below. Open Odin (Jodin3 will not work! It is not fully functioning, do not try it.) and boot device into Download/Odin mode. On your computer, you should see 'Added' in the logs. If this does not show up download the Samsung USB Drivers. Select AP and then select the stock firmware. Now flash it. This can also be done through TWRP
For bootloop and frozen Android/Carrier logo just do Method 2. You usually will keep all your data.
FOR 'VERIFICATION FAILED' YOU CANNOT RESTORE FROM A BACKUP!
FOR BOOTLOOPS AND FROZEN STARTUP SCREEN, YOU CAN!​

One weird error I'm getting all of a sudden is "Custom binary blocked by FRP Lock" when I tried to reboot my phone. Any ideas?

Please describe this issue in further detail. Has this been happening out of nowhere, or did you just try flashing something via Odin/Download mode or TWRP.
Also, before flashing did you enable OEM unlock
This also happens when something flashed via Odin/Download mode is incompatible.
Are you still able to boot into the default system partition? If not safe mode?

I should have updated my post, I'm not sure what happened but I flashed stock through Odin and the problem went away, after that I was able to flash twrp and root/install other roms.
It's still weird that the problem happened out of nowhere, not sure what triggered it.
It goes away when u log in to google with the last account that is associated with the phone

Probs OTA. It happened to me my first 3 tries. Ended up factory reseting, and installing fresh via Odin, didn't fix it.
I just turned off auto reboot on Odin, and then pulled my battery on my J7. Booted up straight to Recovery from there.

Hi, I tried to root my phone and I got this error, I don't mind restarting the phone, but isn't there a way for me to backup my data (photos mainly) first?

Sorry I didnt respond.
Looks like you didnt flash encryption breaker. Keep this on your SD Card as its a great way to recover from these errors, and you will need it when you flash ROMS.
Just boot in recovery, flash ashix no verity no encrypt, then reboot into system. You shouldnt have this error.

He's referring to the encryption breaker file ("no-verity-no-encrypt_ashyx.zip") in his first sentence. That is assuming you already had it and should be keeping it on your SD card all the time for flashing ROMs

I have a samsung j700t ud that had the 7.1.1 update installed from tmobile or samsung and it caused the to remain in a continual reboot loop until the battery of the phone dies. Will the methods above repair the issue?
Stuff I've tried:
1. Wipe cache
2. Called samsung and tmobile
3. Used samfirm to download firmware to use with odin that was successfully done but the reboot loop still remains.

Was the update sent out to you, or did you download it from SamMobile?
If the update was sent out to you I'm afraid I cannot help, but if you flashed it from SamMobile use an older version like Marshmallow or Lolipop.
EDIT: Make sure you factory reset device and wipe cache after installing from SamMobile.

How to recover from Verification Failed without losing data ?​Does installing TWRP via Oddin Works and does it able me to transfer my data after installing TWRP ? I dare not try doing it as i have never did it b4

TWRP soft brick?

After months of deliberation I finally decided to root my Note 9. It was the first time I've ever tried rooting and it seems to have gone horribly wrong. To root the phone, I followed the guide in the video titled 'How to Root Galaxy Note 9! [EASIEST METHOD]' on youtube which has an instruction link in the description. As a new user here, the forum doesn't allow me to post links yet, so please just type the title on youtube and it'll come up as the first result.
What I did was:
- unlocking bootloader
- Flash AP file with TWRP version 3.4.0
- Wipe data
- Since I was worried about using a software from an unknown source, I then flashed the official magisk v20.4 instead of the 'N9-S9_root_for_oem_issue_devices_v3' file recommended in the video.
After doing so, the note 9 restarted and showed the error message "Verification Failed, Unable to restart your device. The Integrity verification has failed. You need to reset your device to factory default settings. This will erase all your data.". I allowed the phone to reset.
Following this, the phone restarted and showed exactly the same message of 'verification failed' and no amount of going through the rebooting process resolved the issue. I googled the issue and was advised to flash the phone with Odin by going into download mode. I then tried to go into download mode, but the phone will simply not go into it and tries to restart the normal way. I also tried to connect to my laptop to see if I can flash with odin but the phone was not recognised at all by the computer.
I then tried to reboot using the twrp key combo and this worked. I then decided to try flashing with the 'N9-S9_root_for_oem_issue_devices_v3' file in the tutorial. Yet, this led to the same issue as with the official magisk file.
Looking at some rooting tutorials, I see that some of them recommend flashing CSC, AP, BL and CP instead of just the AP in the tutorial I followed. I then thought that perhaps the issue is I need to install a ROM on the device. I therefore tried to load the lineage 17.1 ROM in the micro SD card and installed it (top left option on twrp 'install') as well as the magisk and disable_dm_verify_forceencrypt zip files.
In hindsight, this was a stupid move from me - I did so I was in full panic mode at that point and desperate for a solution.
After doing so, the phone rebooted and showed a booting animation of a single blue curved line stuck with a circle rolling from right to left on it.
I left it for a while, hoping that it meant the new ROM was booting. 30 min later it was still stuck on the animation!
I then tried to reboot the phone. Pressing power button did nothing. I then tried different combinations and eventually power + volume up + bixby allowed it to restart in TWRP mode.
As of now, the phone is still in TWRP mode. The phone is still not recognised by my laptop and will not enter download mode if I press volume down + bixby when restarting.
I am fully aware that I've screwed up the rooting process and feel awful about it. It was the first time I've ever tried rooting and I really hope it is only a 'soft brick' and that my phone can be saved. I would really appreciate if anyone here could advise what I can do to complete the root process correctly from here?
Many thanks,
Sam
Is there a "download" or "bootloader" option when you press the reboot button in TWRP? My Note9 is on stock, so I'm not 100% certain myself. However if there is, that should take you to Samsung's download screen. This way you can send yourself back to stock if you give up on rooting your device.
BTW, I do recommend following a note9 rooting guide on XDA (it's not too hard to find) over a youtube video, since YouTube videos can often be out of date or a little sketchy.
