root failed (bootloader exception) - Samsung Galaxy S7 Questions and Answers

Hi everyone,
I followed the guide about the root for my S7 ITV. I've done everything step by step and flashed with odin the cf-autoroot.
When rebooted I had a blackscreen and and this error "bootloader exception", with the impossibility to enter in bootloader mode with the botton combination.
Found a way to return to downlaod mode and reflashed the stock rom.
Now my question is how to have root permissions.
I'd like to try again (I always rooted all my android devices and never had an error like that) but I'd like to understand what i did wrong before doing it again.
Thanks

And how did you get back into download mode, as you do not say?
Thank you
UPDATE:- I tried to root my new S7 and ended up with bootloader error.
In order to get back to download mode this was procedure.
When you get lovely green and red writing in error.
Press all 4 buttons, power, vol down, vol up and home, hold all til screen goes black, then straight away, remove JUST your finger off the vol down button.
This will boot you back into recovery mode.
Do not wipe, clear or reset as it will not work, due to your bootloader corrupt which will prevent your phone ever booting correctly.
Press System off and let phone power off,
Leave for approx 30 seconds.
Now Press Vol down, Home and power buttons and phone will boot into download mode.
I am downloading original firmware, the same one which was is currently on phone to save any issues.
I will then be able to freshly install firmware with odin and then read how to root again without trying to get the bootloader error again.
Best wishes

unbrick samsung galaxy s vibrant.

i have a real problem, trying to flash my samsung vibrant with odin, (installing the unofficial update) my phone was bricked, i cant get into download mode, the key combination vol-up + vol-down to get to download mode is not working, i can't get into recovery mode either, (well getting into recovery mode has never worked) i tried using adb reboot recovery with sdk and it comes as device not found.
Am i screwed or there is any way to unbrick?

Take out the battery, wait a full minute. put it back in and the case back together without inadvertantly hitting either the power or up/down keys. Now press the down key. While holding it down, hold down the power key. If that doesn't put you into download mode, you have done the impossible. These phones are (almost) impossible to brick.
I have seemed to have done the something similar as I was trying to reflash with ODIN and the phone went black, I left it alone for several minutes and now when I try to turn the phone on I just have a graphic with a phone and a computer with a little triangle with an exclaimation mark in the middle and nothing else happens.

I really think i have the done impossible, there is no download mode nor recovery mode, (well, this has never worked) i don't know what to do, i'm getting my phone replaced.
I tried using adb on my computer, but the device is not found, my computer doesn't recognize my device.

i beg to differ
nothing is working for me either
So I went to This Site pathikshah. com /blog / install-android-2-2-froyo-galaxy-s/ (sorry about the spaces new user and xda wont let me post links, not spamming honest), I did exactly as it said it was working as planned until it reset after install. First instead of the vibrant screen coming up it now says:
Galaxy S
GT-I9000
Then It goes to:
Android System Recovery <3e>
on that screen it says twards the bottom:
update media please wait
E:Cant mount /dev/block/mmcblk0p1
(Invalid argument)
E:copy_dbdata_media:Cant mount SDCARD:
your storage not prepared yet, please use UI me
nu for format and reboot actions.
copy default media content failed.
so when I try to scroll through the recovery menu I have to push vol Up to scroll down
also it does nothing when i press the ok button (power button), unless I hold it down then it resets and goes back to the same recovery screen
I rooted the samsung galaxy s then added a rom and the rom is crashing my phone I've tried aboslutely everything don't know what else to do.
i also have a problem
i have install ROM manager and make a back up
went i try to recovery my backup it give me first the original recovery mode i know i have to select update.zip to access the clockworkmod recovery (ver 2.5.1.2 last one) i use the option restore and start it
now my phone just reboot in recovery mode
i'm looking if some one have a working ROM backup
tnx for your help
Drago.

Thank you for the video link. I was up to that point unable to get the download/shoveling droid screen. Now I'm in the process of finally getting the phone back to stock after downloading the t-mobile update that cam through and bricked the phone.
no downloading mode
Hi i was hoping this will help me to reenabeling my bricked samsung. But i cant get it in to downloanding mode. the 3 button way isnt working and the way showed in the movie neither. Is there an other way to get the phone back to work?
I have tried all the methods posted here as well as many others from the link posted above. But to no avail.
I did everything successfully up until the reboot. Whereupon, it would not start. No amount of button combination helped me. And taking out the battery pack is no help either. It just won't start. I could use any advice.
Thank you.
I'm in the same boat now, attempted to odin back to stock and now I have a brick. It's just blank, I cant get it into download or recovery mode using any method described.
Is my only shot the jig method I've read about now?
EDIT
Nevermind, I got it. Pulled the battery, replaced it, held down both power buttons, inserted usb (already plugged in comp w/ odin open), boom..entered download mode and flashed..

Remove the battery and insert it again, now keep pressing the volume buttons and connect the USB cable to your phone, the usb cable must be connected to your pc first.
hey, i also experienced bricking my phone. is there a step by step process how to unbrick it? i need urgent help please. by the way im using samsung galaxy s 4g (
after i have gone to download mode. my computer cannot recognize my device. help me please.
to the post above me. Sounds like you have a bad usb data cable. Grab you a new cable online and you should be good to go
I'm assuming you have already downloaded the drivers to your computer. Sasmung.com will have them

[Q] Bootloader Loop. Help.

Okay so this is what happened. I had CM10.1 installed on my sgs3 (verizon). I followed this guys method to make my phone like i just picked it up from the store. Then i update to the latest version of android. After that i figured i would root it. The thing is that i somehow mest up while rooting it and my recovery mode didnt work so i used this method again
and now my phone is stuck on the inital boot sequence. Help me please. I didnt realize that your phone had to be rooted to use that method. the first time it worked fine. then the second time i forgot that that process unrooted my phone and did that method anyways.
Pull Battery.
Wait 30s
Leaving device Off,
Enter into Recovery mode by -
Holding 3 buttons at one time:
Power, Menu and Volume Up.
Do a Full Restore/Wipe
honk if you think captcha is dweeb paranoia!

What I did was the same as above followed by vol down.. otherwise it went back to bootloader odin mode (stuck). I also deleted odin for whatever effect that could have had. Then I flashed a new rom with twrp.
Power, Home & Vol up gets you into Recovery mode.
Power, Home & Vol down gets you into Bootloader.
Glad you got it working

need help to my s8 plus

After a stupid attemt to root the phone it got stuck booting. I left the phone in the charger booting for 5 - 6 days now.... nothing. Frosen stuck. So i try recovery. Same boot error... i try download mode. . Yes.. but odin will not flash the phone it says "nand write error" and i have tried different pit files and different stock files from sammobile, and files from xda root and stock and more.. But still same result. Hard working and no progress in any direction. ??
Can anyone please give me some advices how i can try to fix this problem? Other then what i have tryed before
Have you tried the following ?
You don't have to do the timing trick with the odin firmware at all! all you have to do is:
1, load into download mode (bixby volume down, power button)
2, click cancel (volume down)
3, load into download mode again
4, click continue (volume up)
5, flash, no error now! No need to flash another bootloader or etc, just every time you want to flash anything use this trick.
I read the above on a Youtube video last Fall, don't recall which. It got me past repeated Odin fails.

bricked s7 edge HELP!

hello
i fear i may have f##cked my phone and am panicking!
i installed a custom rom and the installation seemed to go well but aftetr when i rebooted it seemed to stay on the loading screen for ever even after multiple reboot attempts. anyway i messed around with it (not remembering what i done) and everytime i boot after it shows the s7 edge text it immediately loads a red screen. i have tried to get into recovery by holding home, power and vol up but again boots to red screen. i can boot into downloading mode by holding home, power, vol down.
so ive done some searching on google and it points to i need to flash stock rom with odin whilst in download mode. i got the stock rom for my model and attempting to flash but after sboot.img it fails. (screenshot attached).

That error means it's the wrong firmware. Flash the stock that was on it before you messed about with custom ROM.
Also please read ALL instructions when flashing custom ROMs, some take 15 minutes on first boot.
UPDATE
the error only happened as i wasnt flashing the very latest stock rom. downloaded from samsung website and now is working fine
phew

I Flashed My Note 20 Ultra With Recovery.img And Now Its Stuck On Orange State "Bootloader Unlocked" Warning Message!

Ok Guys So I Shouldn't Have Done This But I Used Fastboot To Flash Recovery And I think I Did It Wrong. It Said "ok" And Finished And I Rebooted Phone It Resetted And Then Stuck On The Orange State Bootloader Message. I Do The Recovery Mode And Goes Black And Nothing Is Responsive For a While, Sometimes Longer Than Others. This Happens If I Start Phone Normal Or Try Fastboot Or Download.
Because Of My Mistake I Cannot Connect To Pc Software And Im Not Sure Of What I Can Do. I Feel Like Im Not Going To Like The Answer For This But I Got To Take The Blame For This.
Btw i Have A Samsung galaxy Note 20 Ultra Sm-N986u
I think your phone is hard bricked
so you can't get fastboot using volume up+power or via adb?
rescue from manufacturer site pos or just device not being recognised?
It isn't hard bricked it's just way of Samsung trying to make life of simple people more difficult, people who paid for Samsung phones lots of money.
To sort that screen issues what you can surely do is,
Simply press volup + voldown buttons at the same time, no matter if you're on that orange screen or whatever just press those those two buttons at the same time and keep pressing them while you connect your phone to pc. you will boot into download mode. Then flash stock firmware for your phone. After stock of flashed Reboot and start your phone, go to developer options see if oem unlock option is there if it is then oem unlock it if it is not then go back to settings manually change date to year ago, then go to updates disable auto update, connect to WiFi, and press on update several times untill window shows up saying no updates, then go to developer options you should see oem unlock, unlock it.
Then boot into download mode and make sure you have working copy of recovery.
And make sure you follow instructions of whoever recovery you installed on how to boot into recovery. I have S20 plus and too had troubles with it, and the only working recovery for my phone is twrp customised. To boot into it after flashing recovery from odin auto reboot disabled I pressed voldown and power, USB cable connected, then after screen goes off I changed from voldown to volup while kept pressing power button and cable connected. Orange screen with warning showed up for 5 sec I kept pressing and it bottled to twrp and then I was able to install custom rom beyond rom and while installing in aroma I was able ti choose option to remove orange screen.
That's it.
I ran into the same error. I mistakenly loaded twrp's recovery into userdata instead of ap section. The phone was stuck at the orange screen and nothing was happening whatever i pressed. I waited till the battery to dry out and with 0% battery, i directly connected to pc and was able to get into download mode. Then i flashed stock and everything is now back to normal.
