Samsung Galaxy S7 bootloop - Samsung Galaxy S7 Edge Questions and Answers

I tried to root my phone using odin to flash TWRP. Through that i installed SuperSU and rebooted the phone. Now it is stuck in a bootloop. What went wrong?
btw i can't wipe dalvik cache via the advanced wipe (it says invalid partition)

First of all, boot into download mode, then install your stock firmware via odin to get out of the bootloop. Then use chainfire's autoroot to get root, then with flashify install twrp.img and you should be good to go.

Thanks. Though i hoped there was another method cause as far as i know installing stock firmware wipes the device and i didn't make a backup beforehand.

Yep, the most important thing is to always make a backup. Because without that, the only way is re-installing the stock firmware. And when you have installed twrp, be sure to format data, so that twrp could decrypt and access your internal storage (that's why you were not able to wipe cache)

If i do a factory reset with TWRP, will it wipe any of the internal data? (pictures, messages etc.)
because the factory reset screen says that it's not included:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

Well, i just tried a factory reset and that fails too. Unable to mount /data.

That's the guide i have been using to root, yes. And yes, i flashed that file along with SuperSU.

I see.. if that file did not fix the bootlooping then I'm afraid the only fix is like the previous poster said
Either flash stock again with Odin
Or format data in twrp

Ok, i somehow made it so the phone booted up and initialized. Now i got the problem that the google play store keeps crashing.
Edit: I also can't download my whatsapp backup data (says insufficient storage, which is not the case)

I also can't download files with the chrome browser (it says no sd-card found). If i use the stock samsung browser it works though.

freedom pop sprint galaxy s4 wont start

I installed an update that automatically downloaded to my sprint samsung galaxy s4 which came with freedom pop "service", it restarted and now goes into a boot loop. With the key combo i can boot to TWRP or a Download option, however, I'm not sure how to proceed. I would like to have it without any freedom pop to use with boost service. mostly i'd like my phone back.
thanks for any help you all can offer.

Yes i would like to know! I would love to be able to run the OTA update without causing issues, and if all i have to do is wipe dalvik n cache on boot after the OTA update that would be awesome!
Sorry should have been more clear, the update does not work. Wrong signing keys. It sends the system into a boot loop. You boot back into the O's but after about 30 seconds it begins applying the update again and send you into twrp and updates fails, reboot, wait 30 apply again twrp, etc. Etc. The way I got out of the loop was wiping dalvik and cache and now I can use the phone again without boot loop. We need to wait until someone creates a twrp zip for the update.
Mine is full wipe >> flash stock 24.49-18-3 >> update 24.49-18-4 via OTA then flash Su 2.62-3 >> Done.

I still dont get you, first you say the update does not work, then you said it worked after you cleared dalvik and cache in twrp after it had been applied making it work?
Not TWRP flashable, but someone posted the full firmware here.
I could not get the OTA to go on my phone, kept failing.
I just fastboot flashed everything in that zip according to the flash script that came with the zip except recovery and didn't wipe userdata. Booted into new system to confirm everything was ok, then TWRP flashed systemless supersu and Frankenclark. All is good. Not as simple as TWRP flashable, but way less disruptive than restoring to bare bones stock to take an OTA.
How long does it usually take on a new twrp zip?
oh someone please get this going! i hate this annoying update notification every day! twrp zip would be awesome!

decryption unsuccessful

Hey everyone,
So I have been using Oreo beta B12 on my A2017U for a few weeks and wanted to check out Lineage and after having some qualms about Oreo and stability, decided to go for Lineage 14.1.
Using TWRP I wiped (standard wipe) and flashed the bootloader, modem, lineage, gapps, and Magisk. In that order. Upon finish and reboot it tells me, Decryption unsuccessful, I must reset my phone. But when it goes to wipe it fails, i see the following:
{
"lightbox_close": "Close",
"lightbox_next": "Next",

}
It seems to be stuck like this, and I don't know what to do to proceed. I could try some things, but I don't want it to get worse because I wiped something crucial.
Thanks in advance.

Flash B12 Beta again and flash 3.2.1-8 and decrypt data (format data )with 3.2.1-8 and flash LOS14.1( bootloader.modem,los,twrp 3.2.2-0 ) you must install twrp before reboot system.

So, would you mind explaining what actually went wrong? Did I just fail to decrypt/format the data before imaging? Should I just be sure to format /data every time I flash a new rom?

This guide is for your twrp to recognize your internal memory and the available memory that is in it since we all face this problem that presents twrp in internal storage.
Warning: This procedure will erase all the data of your device such as google accounts, messages, root, that is to say it will remain factory mode, so you will need to reconfigure the device, I add images of the steps so that it is as comprehensible as possible to understand.
When you install twrp and start it for the first time we will get the following information we just need to confirm the action Swipe to Allow Modifications.
So we visualize the following menu with the options offered by twrp, we will only focus on the option Wipe.
We choose the option Advanced Wipe.
Check the Data box and we choose the option Repair or Change File System
We choose the option Change File System
We choose the option EXT4
We choose the option Swipe to Change, When confirming the action your device will erase all your data stored in the internal storage
Twrp will recognize your internal storage and capacity
Warning: You must re-flash Drm-fix.zip. magisk.zip to be root on your device
Hello,
Thank you for your guide.
I have follow it and it was working, I had the possibility to flash my new ROM.
But as soon I restart again in TWRP, the data partition is again crypted and TWRP can't mount it.
We have to format it again.
Is there a way to decrypt it definitively, so to have the possibility to update a ROM without erase the data partition?
Thank you in advance for your help.

No you have do it again after fresh installation
Thanks for your reply.
OK. So with a ROM like OmniRom for example, on which a new version is released each week, there no way to update our device each week without loosing our data?
If it is the case, I hope that a new version a TRWP will fix this issue soon.

On the Omni ROM, you have an update tool which download the zip file of the ROM, and allow to restart directly in TWRP and launch the flash of the zip file.
But the process is blocked due to this encryption issue.
The only way I have found, is to restart manually on TWRP, format the data partition and then flash manually the zip file to do the update.
But it will say that at each update I loose my data... [emoji17]

Means updating OmniROM is wiping data partition?

Not automatically. But it seems that I don't have the choice to format it manually to have the possibility to flash the new version of the ROM.
Otherwise TWRP generate an error with saying that the data partition is encrypted.
I will try again on the next week when the new version of the OmniIROM is released.

TWRP : Bootloop after restoring SYSTEM on A205F

I was debloating my phone and some deleted wrong file in the system. And now when I restored System using Skyhawk TWRP Recovery my phone got stuck into a bootloop. I had to flash the ROM again and got all the bloatware back.
Is there any way to get this fixed? None of the tutorials have helped me so far.

Use TWRP / OrangeFox in the future. I recommended TWRP but I use OrangeFox because of password protection feature.

I have everything working right now. But the phone goes into a bootloop if I restore the System. I used to just flash the rom again if something goes wrong. This was the first time I tried to restore a system backup.
Recovering Data partition works properly tho.

Yes. Backup's and Restore's work perfectly for me. I highly doubt either one can restore the other's backup data. (Yes, OF is based on TWRP.)
