Can I flash stock recovery back? - Samsung Galaxy S7 Edge Questions and Answers

Hi Guys,
Hoping someone can help and tell me that Ive not bricked my brand new S7 edge
I have experience in rooting / flashing a number of android devices so I was quite confident in what I was doing.
So I was trying to root my stock rom, I flashed TWRP using Odin which worked fine then I flashed the Super SU. When I booted it then asked for a PIN to boot, it definitely wasn't what I set and would have only set it to 1 thing. So I did some googling and found that I could clear data or remove the pin key files but in TWRP it couldnt mount data and I tried re-formatting but it sat there for over half an hour and I had to hard reboot. TWRP now just freezes at the splash screen during boot which confuses me cause even if I switched off during re-formatting, I was only on the userdata so surely that shouldnt affect TWRP? I then got to the stage where I thought entering the max PIN attempts would just wipe data but no it tried to boot into TWRP which is useless cause it doesnt get past the splash screen.
I can still get into Odin mode, is there something else I can try flash? I had tried reflashing TWRP before but it was still freezing at the splash screen
I thought of maybe wiping data over adb but I dont think I can do that unless the phone boots or gets fully into TWRP?
Any help much appreciated.
Thanks

Need Help Reviving my S7 Edge (SM-G935A)

So I went through the rooting of my S7 Edge through a swapped ROM. This hasn't gone well for me at all. Once a week, all of my apps crash so I use SmartSwitch to backup, factory reset, then restore just to have a functional phone again. I tried using ODIN to flash what I think is the stock rom, only for it to fail on me. I was told on a thread here, that if I encrypted my phone through the settings, then I would be able to just reboot, decrypt and problem solved instead of having to restore. A normal reboot only put the phone into a fixable bootloop, so I figured I would try the encryption method. Once I rebooted, the phone took me to the decryption screen, and after entering the password, the phone won't do anything. stuck with an unlocked lock, and a spinning set of half circles. I can restart the phone but it wont seem to boot into download or recovery which could be due to the encryption. I would love some help so I'm not sitting on a $900 paper weight. Please lend any assistance and ask any questions, I just want a working phone again.
If you ever get this fixed Please message me. I have pretty much the same exact problem.

TWRP Issues after Flashing new ROM

Hello all
I am having a little bit of trouble with my TWRP recovery after flashing an updated version of a custom ROM, i have been using for a while.
I am using the latest version of the Pure Nexus ROM, and am currently un-rooted. I earlier want to try and clear my davlik cache as i was having a few little issues with some things, and wiping this has previously fixed the issue, i rebooted into the TWRP, and was asked for a password, which i thought would have been the PIN i use to unlock my phone. This then failed, and it proceeded to try and decrypt the partition. I left it doing this for about 20 mins, but nothing happened.
After reading up a little more, and trying a few different potential passwords to no avail, i read up that the password that TWRP was asking me for was related to the fact i had my phone set to ask for password on boot.
I removed this, and tried again. This time, TWRP just got stuck on the splash screen when trying to boot. Nothing happened for a good 10 minutes.
After putting the PIN settings back on, it goes back to asking for a password, that it wont take.
Whats my next option here, im kinda stuck. I really dont want to have to wipe the phone as i have just spent the best part of a week after flashing my new ROM getting it all back to how it was after flashing the new custom ROM i am using..
All help, much appreciated, thanks in advance
What version of TWRP are you using ?

S4 hung on boot

I restarted my S4 this evening and now it won't boot past the SAMSUNG logo. I have tried a variety of things to get it going but none have worked.
1) Soft boot
2) Pulled battery and let it sit awhile
3) Tried to boot into Safe Mode (stuck on the same spot with no indication of going into safe mode)
4) Wipe cache from CWM recovery mode
5) Reboot from CWM recovery mode
Everything is pretty well backed up but after looking at my sdcard it appears that my camera reverted to internal memory about a month ago so I am after any ideas to get those images.
My phone is rooted and running an old 4.2.2 stock Android OS with USB debugging enabled. I was wondering if by re-flashing the OS it might fix the boot issue and be able to recover the images. Or maybe even flash CM. Or maybe some other thing. I found something about adb but I don't want to do anything else yet until someone more savvy than me weighs in.
Unless it's a hardware issue, then flashing a ROM might work.
The other option is to try a reflow. Reflow means heating your phone up so that the solder becomes liquid and any cracks in the solder (which can cause a bad contact), or any piece that isn't seated right, will be remedied.
did u tried to flash stock firmware using odin?
Deleted
I got it going. I first spent a number of hours getting to know adb which was a dead end because I couldn't get it to see beyond the base directory. I then just flashed the stock rom and everything was there including things that shouldn't be like apps, contacts and texts. The phone is back exactly where it was before it boot locked without having to mess with a single thing. I am grateful but a bit confused.

Black screen after factory reset

so... my phone suddenly wouldn't accept my password anymore to unlock. i tried a couple of things, like deleting the files lockscreen files using TWRP to bypass that... but then it got stuck in a "android is booting" screen and everytime i tried to change my PIN, it would crash.
So i went to TWRP and wanted to reflash my ROM (I was using Resurrection Remix), but then I couldn't decrypt the data because ... the password again wouldn't work. so I finally decided to use sideload to try to flash everything again and it works, but the problem is that even after the factory reset, the phone will boot up but there won't be any images. You can hear the jingle play when you first turn on any android phone... but it's all black.
edit: I've tried flashing two different roms: RR & Lineage OS, both will boot up, but same problem.
I haven't been able to back anything up because... well the OS wouldn't boot up and my TWRP was being wonky and I can't restore anything...
Anyone have any ideas of how to fix this? I feel like i could use the format data and start from scratch... and make it work but then I assume that would wipe my titanium backups, which I haven't been able to extract out. so if anyone has any guidance on how to do that, that would be great. I've tried to use adb to extract stuff out but it hasn't worked and now I can't even do it anymore because I don't have usb debugging on.

have you try to re-flash your TWRP? maybe re-flasing your TWRP will work, also maybe installing the original rom will work, and then you can try to flash whatever rom you desire
as i know doing a factory reset from the TWRP delete all of your files, i mean everything. so i don't think that you still have the backup files
Flash the Official recovery of the oneplus 5 and then install OOS by adb into thé recovery.

S7 Edge just run in download mode/ twrp stuck at first screen

Hi guys, I was trying to restore the stock firmware on s7 edge but I don't know exactly went wrong but right now I'm able only to put the phone in downloade mode and anything else.
And sorry for my bad, bad english.
First of all, I flashed the black peark about 6 months ago and I was just trying to remove by flashing the stock oreo firmware via odin but i was stuck at “SetupConnection” so (after that i saw the black pearl has been updated so i try to install it again) I tried booting into twrp and wipe all the partition but I was getting the error “Unable to mount partition”, what I think just broke my twrp is that to get rid of that message I tried to change the partition file system of data to ext2 (in this way I thought i could have got back in ext4). The last 2 lines were ”formattin…” and “done” but nothing happened and when my phone rebooted i was unable to do anything except going in download mode.
Please Help, I need to get my phone back to life.
Re-flash
You might need to re-flash a ROM to your device using ODIN and if you're going to root then make sure that you use the Samsung AntiRoot Removal Kit. It seems that you messed up somewhere along the line and need to start from scratch. If you get stuck and require help, just let me know. I am no expert but I'm here to help others.
