Deleted my phones OS, could use some help. - Samsung Galaxy J7 Questions & Answers

Yeah I messed up, bad. So I'll give as much info as I can. First off I am incredibly newbie at all this. I have a samsung galaxy j7 sm-j700p (j7ltespr) through virgin mobile. I originally had my phone rooted with the most recent version of magisk, and twrp. I attempted flashing smalipatcher and got stuck in a bootloop. I first tried recovering my backup, but was still stuck in a bootloop. My dumbass then went into twrp and did an advanced wipe ticking all boxes, thinking this would fix my issue. Whole OS gone. So I tried using Odin to flash stock firmware and everyone I tried failed. After that I tried flashing lineage but got a kernel is not seandroid enforcing error or something like that. So I'm lost at this point, I've been up and down the web, these forums, anywhere i could find, And everything I tried has failed. Can anyone possibly help me out, or point me in the right direction?

Do you still have accesss to twrp? If yes, wipe internal storage and system, dont wipe RECOVERY, that is twrp, then flash a custom rom, later if you want, you can install a official rom with odin
Edit: system means OS,sorry.

[Q] Stuck on bootanimation. HELP

Tried looking everywhere, but couldn't really find anything. Any help is appreciated!
Alright some background info
I rooted my phone and unlocked the bootloader successfully. I wanted to do more, so I flashed TWRP onto my phone using JRummy's ROM Installer. I followed all the steps and successfully booted into TWRP recovery. I created a Nandroid backup and when I tried rebooting my phone it gets stuck on the 4G LTE boot animation.
I then tried wiping the cache etc. and restoring the backup I had just created. To no avail, the phone kept getting stuck on the boot animation. I've tried restoring the backup multiple times with no success.
On my last attempt I checked another box on the TWRP restore page, I think it was the VG5 verification or something. Halfway through what I though was going to be a successful restore, my phone reset and got stuck in the boot animation again. Now when I boot into recovery it's the stock recovery, not the custom TWRP as before. Tried clearing everything/factory reset and it still stuck on boot animation.
As a college student I'd like to get this figured out as soon as possible (hopefully before midweek, Friday at latest). If I can figure this out with your help I'll be very grateful.
If I can't find any other way, I'm willing to flash stock back using ODIN and seeing how that turns out. Also my home button is a little sticky so I doubt the Verizon worker would be able to boot into recovery or download mode.
Any suggestions?
For those of you TL;DR
1) Rooted phone / unlocked bootloader
2) Flashed custom TWRP recovery onto phone
3) Created a Nandroid backup from recovery
4) Tried rebooting and gets stuck on 4G LTE boot animation screen
5)Wiped cache etc. and retried multiple times. Doesn't work
EDIT: I flashed stock through ODIN and everything seems to be in order. I'll be trying to root and recover everything through TWRP again and if it doesn't work oh well. My end goal is to have a custom ROM
Maybe this will help you
Okay for your problem, if you can go to Download Mode and your recovery back to its stock form, your last option will be flashing it through Odin. There are several method and guides How to Flash via Odin. I will link to you all the guide and try it so your phone will be back to normal. Choose only 1 method
1.) [HOW-TO] Unbrick your soft bricked Galaxy S III (+ bootloader brick)
2.) Verizon Offcial VRBMB1 Odin Files, VRBMF1 Odin Files, and VRBMF1 Update Files
Must read first the guide and download all the necessary.
If your phone gets revived, you can try this method and choose TWRP recovery and update the recovery.

Thanks for replying
I've got everything back in order now. I'll try installing AOKP or something

That's good to hear

Rooting mistake! Can't reinstall stock firmware, no root, no recovery.

I desperately need help! let me start off by saying that I'm usually decent at figuring problems out myself I've lurked on XDA for awhile and have had many a phone that I was able to root or fix myself.
However this issue is impossible. I've made a mistake and tried to root my phone without upgrading to the version the root was originally intended for. I was using the CF auto root that I've found here at XDA. Now I am stuck on the "Recovery is not seandroid enforcing" error whenever my phone reboots. Everywhere I've searched says to boot into recovery but this is the message I get when I try to go into recovery?
Also how can I flash the stock firmware when my phone was not successfully rooted? CWRM or TWRP won't work without root access. So that leaves me as follows, I can't flash firmware without root access, I can't get root access or stock firmware without booting into recovery, and I can't boot into recovery without un-corrupted firmware? Do you see this giant loop of impossible I've roped myself into? I've tried using Odin to flash the firmware and I always get the "FAIL! (Auth) message right away. And as far as rooting goes I know of no other way other than with my original firmware.
Sometimes I am able to boot into my phone if I am lucky but I can never get into recovery or factory reset. This is all so frustrating as I had an old phone exactly like this one that I was able to root correctly not before finding out it wasn't unlocked and had to send it back! Is my phone screwed?
My phone is a Galaxy s5 SM-900w8 4.4.2

TWRP doesn't actually require root, it can do what it wants without it. It needs root to use adb while booted into TWRP but that isn't because TWRP requires root to do it, it is because adb requires root.
Root is sometimes used to flash TWRP via an app.
Have you tried flashing TWRP via Odin then seeing if you can boot to recovery?
Also, if you get lucky and the device boots into system, try going to system settings>backup and reset then find the factory reset setting, try factory reseting it that way and then see if you can flash TWRP or your stock firmware via Odin.
Are you booted into download mode when you are flashing stock firmware in Odin?

I've tried doing a factory reset if I get lucky and it takes me into the main screen but immediately it gives me the "seandroid" error message the same as if I press volume up, menu, and power. I am able to boot onto download mode ive tried this to flash firmware but Odin gives me a Fail (Auth) message each time. I'm not even sure if TWRP has a version for my phone yet I'm not sure much about TWRP. If there's a way I can break this chain I'll try anything.
TWRP working so far
I found a custom version of TWRP and thankfully was able to flash it on my phone using odin. I was also able to get the Root working with TWRP as well. I'm going to play around with the phone awhile longer to see if everything is fine. I no longer get the "seandroid" error message while booting up the phone however it does briefly appear upon loading into the recovery but so far TWRP takes its place after a few seconds. It worried me at first but as long as TWRP kicks in each time it's a good sign. I'll leave the thread as unresolved for a while longer in case anyone has any further suggestions or in case something goes wrong but all my thanks goes out to Droidriven!

Good to good, glad you made progress, hopefully that's all you'll need to do.
I don't see how I was much help though. All I did was explain TWRP not needing root.

Understandable, however I never would of thought to try TWRP without your suggestion. It seems when you are stumped the answer is right there all it needs is someone else to chime in and point it out. Like trying to beat a hard level over and over sometimes just give the controller to someone else and they will get it their first try lol.

By the way, when flashing stock firmware via Odin, root is not required. The only time root is required to flash stock ROM is when flashing a stock firmware that has been converted into a custom recovery stock flashable.zip. It is not uncommon for someone in this community to convert stock firmware into a recovery flashable .zip. This is used so that the device doesn't lose root or custom recovery. When flashing stock the normal way via PC, it removes root and reverts the device back to stock recovery. Then the device has to be rooted and flash recovery again. The stock flashable .zip avoids all of that because it gets flashed in custom recovery, this way, recovery is not lost and root is not lost.
This only applies "IF" someone converts the firmware to flashable .zip. Not all devices have a stock flashable .zip available though.

I accidently deleted my OS with TWRP because my phone was bricked

So, i tried to flash a supersu on my phone with twrp, then my phone got bricked (it was stuck on the samsung boot logo). And then i took my SD Card out and saw that all my images was on that. So i thought i could just wipe my device. I went to the twrp, and selected wipe, went to advanced and selected everything. And i had no idea "Internal Storage" was my OS. I dont have any backups sadly. But i have TWRP and my sd card. The only problem is that ive tried to install samsung galaxy s7 stock firmware, but twrp says they are all corrupt. Where to i get a stock firmware that is not corrupt?

You don't use TWRP for stock firmware you use it for custom ROMs
ODIN 3.12.3 or newer is for stock firmware
Really should have done a lot more learning and reading before playing around

Stuck on Boot screen after flashing TWRP

Hello,
I just flashed the latest ROM for the S8+ (AQL5) and that went well.
Afterwards I tried to flash TWRP, but now the phone is stuck on the Samsung screen.
I then followed the guide I found here to use the BL file of AQF7 in Odin and spam the Start button so I managed to get into TWRP.
Question is, what do I do next? I restart the system it's the same problem all over again.
No one explains anywhere what to do in TWRP to save the phone.
Can I remove TWRP or somehow save the phone (without wiping my data)
Please help
Can you get to download mode? Then go to ODIN and redo your flashing of the OS and then TWRP. After the flash of TWRP, immediately boot into TWRP, and do Verity if you want that, and your root, if not already done. Clear Dalvik/cache and reboot to system.
It is not uncommon for folks, following TWRP flash, to get stuck in boot loop, unfortunately. Can take a little time, but you will get through it and finally to System.
But I thought all new firmware versions are incompatible with TWRP and cause this error.
I might try to install TWRP again if I flash the latest compatible version (I think it's the F7 one).
Does "Verify" in TWRP make that annoying "Your phone is not verified" message go away? The only option is to Reset phone when that thing comes up and I don't want to do that.
I managed to get out of that by reflashing the AQL5 version and just not installing TWPR.
Kind of scared to retry because everything goes wrong when I try to follow the guides on here or youtube

Swiped right on NO OS INSTALLED

Hi there,
I was trying to install Lightheart 1.0 OS in my SM-G930F after having LineageOS 17.1 installed for some time. I flashed the ROM and also Magisk (although I couldnt flash Gapps as Error 20 appeared). Both the ROM and Magisk seemed to flash ok. After doing all of that, I went on and, although I saw the message of NO OS INSTALLED, I swiped right as for some reason I though that it was gonna be installed anyway (or smth, idk too much about this :silly:.
Now the phone is stuck on the initial loading SAMSUNG GALAXY S7 page, without TWRP access nor download mode access (prior to flashing, I erased DALVIK, CACHE, DATA and SYSTEM). I have tried to flash TWRP with odin, but as there is no download mode access, I had no luck.
I´m reading more about what could I do, however right now I´m a bit lost and I dont know what are my options.
I would greatly appreciate any help or advice. Thanks.
EDIT: no need of help anymore.
