[help] phone stuck in bootloop - Galaxy S6 Q&A, Help & Troubleshooting

Okay so some of you might know that there is a ram management fix for the Samsung S6 by editing the build.prop file. I tried doing it and my phone went into a boot loop(it just repeatedly show the white text of SAMSUNG GALAXY S6). My phone is rooted by the ping pong method which doesn't trip knox. The last 2 things I want to do is go to a samsung store or flash a stock rom which wipes my data.
I saw a video that you can fix it by using adb. However, when i plug my phone in my pc while my phone was in recovery mode, the pc doesn't detect. But if my phone is in Download or just its boot loop mode, the pc detects but it often says "Your last device is not recognised or malfunctioned" or something like that. Yes I do have drivers installed including Kies3.
All I want to do is just to fix my s6 build.prop file without
1. Tripping the knox,
2.Not visiting the samsung store
3.Factory resetting my phone and flashing a new rom.
Please help. Thanks

I found out that you can flash a zip file that restores the build prop file here:

But I'm an odin noob so... how do you flash it???
***********EDIT AGAIN*********************
Okay... soooo I'm stuck now. I can't even get my s6 to connect to my pc. It just says usb device not recognised.
I already tried:
-Redownloading samsung usb drivers.
-Installing Kies3
-Installing Smart Switch then clicking more and reinstalling usb drivers.
-Using different port.
-Using different wire.
-Blowing into port and phone port to clear debris.
Help :/

N8010 Problems

Hi,
Figured id start off by explaining the history on my Samsung Note N8010
A while back i installed Hyperdrive Rom RS8 (i think), no problems, flawless. However it did change my device id to an N8013, not sure why.
Recently i wanted to use SkyGo Tablet app, however root cloak and Voodoo does not cloak SkyGo Tablet app on this specific rom so i figured id revert back to the original 4.1.2 stock.
I used Mobile Odin, grabbed the zip/tar from the Sam-mobile and hit go.
On reboot, it would not load in, stuck on the Samsung Note 10.1 splash. I do have access to download mode and recovery mode, but it's labelled Android System Reocvery <3e>.
It is worth noting that USB debug did not work on Hyperdrive, so currently no matter what computer i connect this tablet to Odin, Kies or anything will not see it.
When trying to "apply update from sd card" i get E:\ mount problems, it pretty much fails every time.
Any suggestions?

The original issue is probably one of two things. If you downloaded the rom directly to your device its Likely a bad download. DID YOU CHECK MD5 Before flashing. There are also limitations to Mobile odin.
What i would suggest is to uninstall Kies . Make sure you have no other android devices installed on your computer .Download the older version again from Samsung website. Install on your computer. Download odin again i think you want the one a version back as well NOT Latest.
Reboot into download mode. Run odin. if it still does not see your device check Device manager and see if its showing up with a yellow mark. Look for a post i made last week explaining how to correct usb driver for windows.. Download mode should work with out usb debug on if i remember correctly..

Hi, cheers for the response,
I have tried all of what you have said but unfortunately no PC will see my device, not even an "unrecognized device". I have access to android system reocvery <e3> and Download mode (Odin) but the pc just won't recognized, tried new leads and so forth, nothing.

Flash TWRP in Download-Mode and then connect it to your pc. After doing that, you can use adb and restore your old build.prop

Accidentally deleted my OS on Samsung Galaxy S7. Nothing works!

I have a rooted S7 with TWRP recovery on it and i recently deleted my OS by accident as i was just trying to reset my phone to factory settings. Now the only thing i can do is boot into recovery mode and download mode, or i can just get stuck at a boot loop.
I have googled and googled and seen so many ways to try and fix this issue but nothing has worked for me. Heres a list of the issues i have and what i've tried so far. [Using Windows 10]
Installing Odin (3.12.3) and stock Samsung firmware from here.
Installing the necessary USB drivers from here.
My PC wont recognize my samsung device in either modes (recovery/download) and Odin wont recognize my phone either, as well as i cant find anything under "Device Manager".
Tried using ADB to transfer files to my S7 but when i activate ADB in recovery mode it just loads for a couple of seconds until it displays an error with no explanation.
I even tried downloading ADB drivers and necessary tools i got from this guide.
I also tried wiping Dalvik cache and cache.
I have tried three different USB cables on all available USB slots on my desktop PC and the one USB slot in my Surface and nothing works.
I have tried rooting previous phones but I'm still new to this rooting thing and there's a lot i don*t understand. Perhaps i downloaded the wrong USB drivers, or maybe I'm just unlucky. I just really need some help to understand how to fix this. If it can't be fixed is it possible to remove all traces of rooting on my phone?
The phone needs to be in Download Mode to use ODIN
The only sign it is connected is a COM port lit up at the top of the ODIN window
Add the .MD5 ROM to AP and hit start

SM-G920F stuck in bootloop with stock recovery, computer cannot recognize device

Hi everyone, I ran into a serious problem today with my S6 G920F. I was running stock android 7 with Magisk and TWRP installed, I flashed the firmware using Flashfire from the Google Play store.
This morning the phone decided it would stop charging, a problem I faced with Android M. Anyway I reflashed the firmware package but this time i chose NOT to select the options to inject supersu and save my custom recovery, thinking that I could get it back to stock and re root it from there.
The phone previously would not boot if either Magisk or SuperSu was not installed (after i rooted it), it would just endlessly loop. Unfortunately this was the case after i flashed the firmware .
I assumed it would be a quick fix as I could just use Odin to flash the stock firmware . Unfortunately I was wrong again: my computer gives me an error message "USB Device Not Recognized" no matter how many times I uninstall and reinstall the Samsung Driver, Odin wont detect the phone either. Even Smart Switch is at a loss. The phone is currently plugged into my PC and is charging normally, I CAN boot into stock recovery and download modes.
SOMEBODY PLEASE HELP!! :crying::crying::crying:
Seems very obvious now but I found the solution I found the original cable that came with the phone; plugged it into the PC and just like that the computer registered that it was a Samsung devices and started installing drivers right away, seems like the P8 Lite cable I was using isnt a data cable?
I was able to flash TWRP using Odin and flashed Magisk using TWRP. All is well

(SOLVED) Custom binary blocked by FRP lock message when i try to boot my phone

Edit: It seemed as it solved itself, look in the replies for details
So i have had my gs7 rooted for a year or longer. Yesterday i rebooted my phone and got the error message "Custom binary blocked by FRP lock". Sadly, when i enter download mode and plug it into a pc with odin installed, it is not recognised. Odin does not say anything about a phone plugged in, and windows says the usb is not recognized.
What i think have caused this:
I downloaded an app that allowed me to record internal audio
I turned off developer options, and my stupid ass did not realize that is where oem unlock is located.
What i have tried:
Resetting to factory settings (from recovery mode)
Deleting cache (from recovery mode)
Using odin, but odin does not even recognize my phone
Tried using another computer with odin
tbh, looking at the other posts, i think i messed up. I dont want to send it in for repairing because i will have to pay a lot of money. I have tried sending it in for repairing a while ago. Then my problem was that i could not call with it, but they wanted me to pay the price for a new phone to repair my old phone, since i had rooted it. I did not accept it so i got my phone back, and managed to fix the issue myself. I hope i manage to fix the issue this time aswell.

I have samsung usb drivers installed, and download mode has always been working and has always been recognized by odin ever since this happened. And online all i find is that i should boot into download mode and try using odin, but odin does not recognize my phone, nor does my computer.

Please pay attention to guides when messing about with your phone, OEM and Debugg are critical to being able to modify.

SOLVED!
The issue fixed itself, im not sure what i did. I was suddenly able to connect my phone to odin. Just incase someone reads this with the same problem. This is what i did: installed smart switch and rebooted my computer. Uninstalled and reinstalled samsung usb drivers.
Before i did those things the issue was still there, i was ready to use smart switch, but i tried odin one last time and it worked. Now samsung pass tells me my phone is rooted, even though it is not (my root dissapeared after resetting my phone), its not that big of an issue, just thought id let you know
