galaxy s6 brick- help! - Galaxy S6 Q&A, Help & Troubleshooting

Hello guys
I wanted to downgrade android from 7 to 6 by using odin. I had downloaded original 6.0.1 firmware from samsung site, which was making some errors in odin.
Later I cannot turn on phone, only option was displayed on screen was about fixing phone by smart switch. I had downloaded that app, done completly restoration and now I cant turn on my phone. Only thing I can do is going into download mode, there is no recovery, also combination of vol. down + power is not helping for me.
Has anybody any advices? It should be kernel problem? Some boot files were deleted?

First of if u downgraded to marshmellow so you can flash mashmellow roms you didnt need to , i can still flash marshmellow roms on nougat , so your best option if u want stock marhsmellow rom is to get back working nougat then flash a stock debloated rom
i know ive probly just repeating what everyone says so if u need somthing else just reply

No OS installed?

After flashing a volume mod, everything went to hell with my phone(stock rom)I for force closes on chrome/andora and i couldnt use my phone since i keep clicking ok to the fc's notification but they kept coming back.
so i decided to do a factory reset but i dont know what went wrong that now in recovery when i click reboot after the reset it says NO OS INSTALLED DO YOU WANT TO REBOOT?
does this mean i need to flash a new rom or what? I was on the stock rom and i kinda want to go back to that but i dont kno what went wrong

So you can get into recovery? if so did you make a backup before sound mod? I know tdunham was one of the gents that made the sound mod, not sure which one your using created by who? Tdunham has a restore file for volume if problems arise. so if your using his awesome mods you should send him message. If all else fails or you are jus lazy just odin the firmware file required for your phone. Everything will be the same as before jus not rooted so reroot with method you have used not sure when you got phone but I heard towel root doesn't trip knox.

i used a volume mod to remove the high volume notification
im thinking of odin the firmware but i dont want to lose my internal storage.
I cant make a backup because in recovery it tries to save to internal and i dont have space, i cant figure out how to make it go to sd card.

I would just restore firmware, http://forum.xda-developers.com/showthread.php?t=2742994, this a great place to have stickied, anything new gets posted here for sprint s5. Check your phone firmware first so you know which one to download, do this by going to settings, about phone, then scoll to bottom you should see one of these three firmwares ncb, nd2, ne5, you will want to find firmware file at top in link, if you cant find your firmware there, then go to sammobile.com, then download odin 3.09 from this link, http://forum.xda-developers.com/gal...08-2013-odin-3-09-odin-1-85-versions-t2189539.

Not tryin to be rude jus curious if u were, i hope u can figure this out, i love my phone to death so i feel ur pain bro. Check firmware settings about phone scroll to bottom to find ur firmware. Oh if u do not have developer options activated while on same screen in settings in about phone click the build section seven times it will make developer options appear, then go into developer options which shows in your settings now and activate usb debugging, you this so u can interface with odin, and oh yeah our phones need to be in download mode to flash firmware, assuming u used towel root since u havent used odin yet?!?! You can get into download mode by pressing and holding volume down, home button and power button. Let me know bro!

well i cant boot phone so i cant check what firmware since recovery says no OS installed.
what is driving me crazy is my pc recognizes the phone but odin doesnt
i plug in phone the driver installs but then i get a message with modem failed intallation WTF?
this is the same pc i used to root
is there a way to do this WITHOUT using pc for example downloading a flashable file and do this all through recovery
also when i am in recovery and i press system boot i get a message that says YOUR DEVICE DOES NOT APPEAR TO BE ROOTED INSTALL SUPER SU SWIEPE TO INSTALL??
wtf happend , all i did was factory reset after a bad volume mod
im coming from an evo 4g and it seemed way simpler than this

Okay so u have no nandroids??? If not check the box your s5 came in they usually have the firmware it comes with printed on box. If you dont have that either, i would to jus download ne5 which the most recent firmware has new modem, still rootable, and it will put os back on your phone. After you do this make nandroid! They are your best friend!!!! Oh yeah odin isnt recognizing your phone because on samsung phones there is a download mode, with phone turned off, press volume down home button, and power all at same time keep holding till download mode iniates. It will say like loading custom os blah blah...press up on volume and presto odin is recognizing your phone.

As far as making your computer fully recognize and through ODIN(hope u pressed up button once in download mode makes odin recognize!) I would uninstall those old drivers, type into google s5 samsung drivers, prob doesnt mean a hoot but to just to be extra precise, download install new ones. Maybe try different odin 3.07 ....and when u run odin make sure u are extracting package if zip and right click program once extracted and run a administrator. No need to touch any settings once in ODIN besides loading firmware. Fell asleeo sorry for late response.
Download and install cnexus stock rom from the dev section. That should get you running again.
Do you have twrp? Sounds like you wiped the system instead of doing a factory reset.

well i couldnt get odin to recognize phone in download mode. I deleted drivers and rebooted but i always get samsung usb modem failed. and When i do manage to get in to install, it still doesnt show up in odin(.09 and 3.07) and in device manager there is a yellow triangle in samsung modem.
I will try to uninstall everything and delete samsung registry keys as i saw something in google that it might help.

Hit thanks by accident. Yes it should work although I haven't done it on the S5. Once you get a computer working you can use odin 3.09 and flash my full tar no data file. This will get you up to full NE5 without wiping data.

It depends on where you are now. If you are ND2 now then by flashing the Rom (system) you are only bringing your system up to NE5. To get all of the other firmware up to NE5 you need to do it with Odin on a computer. Because some of the firmware won't update using Mobile Odin.
If you are already on NE5 then you don't need to do anything else after installing the rom from recovery.

This may sound stupid, but at the expense of stating the obvious, are you using the original usb charger cable that came with your phone to connect to your pc. If not, you should. I had this problem 2 phone generations ago, I thought I had bricked my phone. Use the original cable. All other usb cables are a Crap shoot.

[Q] Signature Verification Failed when trying to flash to stock firmware with ODIN

Hello guys, first time making thread here. Hope there are some dev or users who can help me with this very old phone.
So, I previously tried to use Custom Rom [MAK-DROID] but when I get to home screen, it always reboot itself when I press any button on the first step of setting up the phone (I believe it's because the BAND version is incompatible with my phone). I decided to install a stock ROM in order to get it works wi​th ODIN and download mode of course, but when the ODIN say RESET, it will boot my phone directly to [BLUE] Recovery mode, and will say Signature Verification Failed, Installation aborted. When I try to reboot the phone it will always stuck on the Galaxy [email protected] GT-B5530 logo (the one before samsung logo). Tried many possible solutions on internet but still stuck.
If you know any possible solutions, PLEASE tell me about it, for this phone is very important for me currently.

Have you found the solution to your problem?
I think it is the problem with your stock rom, try downloading the Stock Rom again and then flash it. It should work.

Urgent! help needed.

Everything was fine, i was rooted and had custom rom installed on marshmallow.
Then i decided i wanted to try nugat. I went to install the new firmware, but i've hit the wrong section in odin (done it through ap (on old version)) and now my phone sticks at boot screen, cant access recovery where my back up is.
can anyone help me recover where i was? or even start again? thank you.

Hi
Can you get into download?
Some times you have to keep trying multiple times , seen it in other threads , just keep trying to get into recovery or download ....something gets mess up and to get into recovery or download is a matter of trying several times
yea i can get into download mode okay. But i cant access recovery mode which is how i need to get my backup. I have now found the guide to get back to stock basically. but i'd rather figure out why it isn't booting.
I flashed the firmware through the ap button and dont know if thats wrong or right. i've forgotten lol
---edit --- i have managed to install the full android nugat selection. many thanks please close this if needed.

The attempt to flash 6.0 didn't work because of the anti rollback version in the roms for this phone. the furthest you can go back at the moment is to a 20A rom which stays in ARB (Anti-RollBack) 01. To get your phone functioning again, flash this rom using the uppercut method - https://forum.xda-developers.com/tm...ock-h830-20a-rom-flashable-zips-imgs-t3511294.
If you are trying to gain root, you will have to use the "recowvery" against that firmware.

I have this same issue. Can anyone help?
I can get into fastboot but I can't boot the OS normally. As soon as it boots up Settings keeps stopping so I can't get into ADB. I can't seem to boot into recovery with any key combo known to man.
Help? Bueller? Anybody?

Help! Attempting to flash the latest ROM with the latest Odin!

Hi guys,
Over the weekend I attempted to root my girlfriend's Samsung Galaxy S8+
As you can probably imagine, it didn't go well.
Right now I have a phone that'll boot into download mode and I have tried two different (official) firmware flashes using the latest Odin.
Unfortunately, upon flashing, it says installing updates, gets to about 35% and then shuts off.
Any ideas how to get this thing back up and running? All help is greatly appreciated! Thanks!

You can try to flash TWRP in Odin, after that to enter in TWRP with key combination Bixbi + volume up and power pressed in the same time until you in, to flash custom ROM . You can upload the ROM to phone through recovery.
