Recovery img flashed to boot partition - hard or soft brick? - Samsung Galaxy S7 Edge Questions and Answers

Hey guys, I have a samsung galaxy s7 edge SM-9350. I was able to get root access and get the TWRP app. I was attempting to flash the TWRP recovery image, but I accidentally flashed the to the boot partition instead of recovery. After rebooting, I cannot boot the phone. When I hold the power/volume up button I get the option to select recovery/fastboot/normal boot modes, but no matter which one I select, the phone doesn't seem to boot. Do I have any options? I'm not sure if this qualifies as a hard or soft brick.
I have also tried to go into download mode, by holding the power/home/volume down, but that just seems to enter a boot loop. The screen illuminates, but remains black for a while, then shuts down.
The furthest I get into any sort of developer/interaction with the phone is being able to select between Recovery, Fastboot, or Normal modes.
I'm looking for the general search terms to start with. I've rooted my nexus/htc devices before and soft bricked, but was always able to get back via Fastboot/Recovery. This is the first time I've not been able to get into either. Is there some method I can use via the micro SD card maybe?

Install PC SmartSwitch app and try the Emergency firmware recovery option
If that doesn't work then you may need a Samsung Repair centre

Ugg... I had installed Smart Switch, but it doesn't recognize that my phone is plugged into the PC.
It looks like in order for it to work my phone has to be in Download mode or Recovery mode, depending on what guide I read.
And I can't get into either mode at all
Thanks for the response!

I assume Odin doesnt recognise the phone in any situations?

That's correct. My windows PC with the Samsung drivers no longer recognizes that a device is plugged in. I just tried a USB jig. Pins 4 and 5 of the microusb joined with a 300k ohm resistor and it still doesn't go into download mode.

Sadly you probably need a samsung repair centre
Please let me know how you get on with a fix

Does Odin not recognise the phone when you put it in to download mode ?? i used Kies to recover the firmware rather than smartswitch although Kies tells you to use smartswitch it still let me use it to doe the firmware recovery.

[HELP] SGH-I337M Boots first into D/L Mode

I have a phone I am fixing for a friend, so I don't have a complete accurate history of what happened, so please bare with me.
Basically, you put the battery in and it boots right to download mode (Factory Mode), no power button required. I can then reboot it using the power, hold down the Vol-Down button and then I am prompted if I want to enter D/L mode, in which you can use Vol-Down to cancel and it boots like normal.
I have tried the following, nothing fixes it!
Factory Wipe
Root using CF-Auto Root
Every Key Combination Possible on Boot
Odin Stock Install
Kies Upgrade (just stalls on that)
It was not rooted when I got it, and now it is. I haven't installed any recovery yet, but am willing too. It has possible water damage, so it ain't going back to the store anytime soon. I can't even get USB Debugging to appear that it is connected, nor will ADB recognize it. But the USB is working and read/writing.
This isn't my first time working with this sort of stuff, I am just at my wits end, plus I'm a Sony/HTC/LG person, so if there is something I am missing with this wonderful(ly crappy) bootloader, let me know.
Thanks in advance!

If you can hold the vol-down and home button when you boot it up and get into Odin mode you should be about to flash the stock MD5 for your phone. Stock Canadian Odin files here:
http://forum.xda-developers.com/showthread.php?t=2269304
Also make sure to use the lastest version of Odin, 3.07 I believe. After you are done flashing with Odin you will have to boot into Recovery (vol-up when booting) and do a factory reset. This has always fixed any boot problems with my phone.

So did you go into settings, more, developer mode to check usb/debug?
USB debugging isn't required to flash the Odin MD5. One thing I did notice is that you should boot into Odin download mode before connecting your USB cable. I was having issues with Odin not detecting my phone and waiting to connect the USB cable solved that.

Duh...
I was referring going to adb fastboot
see the thing is that flashing did work fine, it just didn't fix the problem. I guess in Samsung terms I am stuck in Odin download mode when turning the phone on. This is why I wanted to see of I could push some standard reboot command via adb to see of it would "jig" it into place, but no matter what I try it always boots into download mode first.
and yes, I did turn on usb debugging

Could you have bent pins maybe where you plug it in? Its doing exactly what a jig would do..

Nothing is wrong with the pins, USB is working fine and can be used in any other mode. I got ADB finally, I guess it was just not playing nice with me before. However, still anything I try the bloody thing still insists on booting first into download mode.
Just an update, it is still booting into download mode, tried a couple different stocks and still no good result. Anyone suggest any of the options in Odin might help work? Like F Reset Time or Phone EFS Clear?

I have seen this elsewhere, one guy suggested, using Keis, and it took him 2-3 times to get the stock to stick.
As far as checking those items in odin, could brick the phone. he also said, he got nowhere using odin in this situation.
Have you tried maybe flashing a recovery via odin? could be the recovery is corrupt.
what does this mean: in which you can use Vol-Down to cancel and it boots like normal. <<< Can you boot to the OS?
I can imagine your frustration here...good luck.
I did try Kies and it would keep getting stuck at 10% (I let it sit overnight) so I had no luck with that...

Yes, I have gone from stock recovery to CMW and back to Stock and still nothing. As for you other question, yes, I can boot into Android. The downside is I can't turn the phone off unless the battery is pulled out. This is why I bought an HTC One and not an S4 lol .. thank god this isn't my phone, but it is frustrating because of all the things I've tried to do to fix it.

The only way I could get it to work was the following; however there is one thing to try before you try my way because mine did this also - after the wipe and flash with flashtool etc. The only way I found to get out the bootloop was to do a factory restore after when its looping. So from the boot screen loop hold the power button until it goes off then on then off again.
Then do the process to get into the recovery so hold down and power then release power as soon as the lg logo appears (first one) then press it again immediately that SHOULD get ya to the grey factory reset screen. Press the power button 3 x and it should do a factory restore and boot up this time. First boot may take a minute it should eventually start up.
Failing that try this - Open the lg mobile support tool and connect the phone in download mode (volume up and power with plugged in usb on mine) then go to options and upgrade recovery. it will download a file usually about 2GB then install it, the phone will reboot at 100% on the phone and 80ish% on the lg tool it will then start into the setup feature,
DO NOT disconnect the phone until it gets to 100% and finishes. This way you shouldn't need to do an extra factory reset.
I understand for this the phone needs to be seen on com 4 (it shows on the phone screen) so if necessary go into device manager with the phone still plugged in in download mode and select com ports then select the phone com port then right click >properties> advanced and change the com port to 4. It may tell u its already being used but don't worry it is fine. Save and exit device manager.
please bare in mind these are just my experiences on MY LG D802 however its worked every single time for me without fail and ive done it a good few lol.

[Q] process.com.android.systemui has stopped

i recently tried to edit my build.prop file on my LG G2 (LS980). i changed
Code:
ro.build.product=G2
to
Code:
ro.build.product=g2
(using root explorer, and mounted r/w) because i read that they should be lower case, and since my phone wouldn't update i decided to see if it would work. rebooted and got the error. the error is so bad that i cant even use my phone. the front touch buttons are missing and i cant tap anything except for the power off/reeboot/enter airplane mode. Also, 9 times out of 10 when i power off, the sprint spark logo appears then screen goes black, then reappears and turns the phone back on. furthermore, when i plug it in to my pc i cannot change it from MTP mode, and im not sure if i still have usb debugging checked. the lg mobile support tool wont recognize that a device is connected even with the latest drivers. ALSO, i cannot enter stock recovery! last night when i first got the error i entered it once, but i decided to look for other options as to how to fix the error rather than wiping. but now I WISH i wiped my phone then, because no matter what i do now, the phone wont go into recovery mode. i don't have TWRP or CWM, and i am rooted. I'm a noob and i don't know what to do at this point, can anyone help me?
i have tred looking for some sort of software that can let me access the phones settings directly through usb, but no luck. i dont even know if such a thing exists.
can you battle your way to settings/apps? hit options, reset defaults
otherwise you may have to boot into download mode and flash complete tot/kdz

[EDIT] i can enter download mode, im in it now. should i just run KDZ or what do i have to do in order to make this work?
you need to download the correct rom for your phone and flash using this... http://forum.xda-developers.com/showthread.php?t=2797190
Same happened to meee!!!
What can i do??

Odin flash failed, stuck in Emergency Recovery screen, cannot turn off.

I was going along ok until I made the fatal error of transferring the Magisk patched file to PC via MTP instead of taking the time to re-learn adb, which must have corrupted it. Thus predictably Odin hung and I am in trouble.
Where I am stuck is being unable to turn the phone off to come back in download mode to start over with stock firmware. I have been unable to find any secret button presses, and the battery doesn't seem to want to die leaving me with an $800 paperweight.
I did search around for this first and didn't find any real answers. Has anyone found an effective solution to this problem? Thanks.

If Odin recognizes you device, you can flash firmware in emergency recovery.

Thank you, but the PC won't recognize the device. What does happen is the emergency recorevy screen tries to come up. I tried starting in download mode with bixby+vol down then USB. I did get the battery low enough where I don't get the teal screen of death anymore, perhaps it is too low for USB to work? What I was hoping for was the charging animation but no luck. Surely this is just a software problem and there is a way out.

Did you try getting into recovery and perform a data factory reset and then see what happens?
Just load the stock firmware BL, Ap, cp and home csc into Odin if you see emergency teal screen. The emergency screen will start loading
Black screen ....Perhaps your battery is dead?
Thank you all for the replies. I had let the battery get low in a misguided attempt (based on advice elsewhere) to get it to shut off. I had to let it charge a while for it to wake up enough for PC to see it. Then I was able to flash in Emergency Recovery mode.
Thank you for the help.

Glad you got your device up and running ?
Maybe someone can help me. I seemed to have borked my phone. I kept getting "Google is Stopping" with no way to fix it, so I tried reflashing my firmware in odin. After I loaded all the files and hit start, I realized I didn't untick auto reboot, so I tried aborting the installation and ended up with screen (I've had it before and got out of it by still flashing in Odin, but now, if I try to reflash firmware while in this screen, it's stuck on SYSTEM in odin.
Any help appreciated!
Try this
That is where I got stuck. Are you trying to flash stock or patched firmware? I had to start over with stock as I copied the patched via MTP instead of adb and it got corrupted.
I think what I did was unplug and reset Odin. Wait for screen to turn off, then make sure it is at least 80% charged. Then Bixby + Vol Down + plug in and you will go back to this screen. Then I was able to flash stock. I had to go so far as to re-lock bootloader and flash stock again since my "OEM Unlocking" was not just greyed out but missing. Since then I've had no time to try again, but at least I have a working phone.
This is my anecdotal procedure, can't say if it is the right or best one.
Hi All,
I was trying to flash the latest firmware for my device (G9750ZCU2ASG4) and during the odin process, my computer restarted which failed the update halfway through. I rebooted the computer, tried again, and it was trying to establish a connection for a really long time, so I disconnected my phone from the USB port on my computer, and held Power and Volume Down to try and force reboot the phone. I was going to try and go back into download mode to restart the process. My phone mentioned something about needing to do an emergency recovery, but I continued to hold down the power and volume down keys and then everything went black on the phone.
I've tried multiple USB cords, all of the button commands known for the device, and have even tried to perform the emergency mode recovery on my device, but it seems like it's in some sort of locked state; What I mean is the phone is stuck on a black screen. I can't "boot" into recovery or into download mode. The phone doesn't even vibrate when I hold the power button or power and down to try and force reboot it. Odin doesn't recognize the phone when I plug it into the computer nor does the device manager on my windows computer.
Does anyone have any experience with this sort of issue or any idea of what else I can do to try and get into download mode to flash my firmware again? All help, suggestions, or comments regarding this are much appreciated.
Sounds like the battery is dead
Hi Dude, I am struggling with the same problem, read this post and it came to me, had to come back and give you the solution.
Press bixby+volume down, IMMEDIATELY after the screen goes off, hold volume up and down while connecting the USB cable super fast.
You have got like 10ms to do it
Otherwise it just goes back to the AVB FAIL screen
Ran into this issue, none of the above worked for me.
This is how I resolved:
1) Placed phone on wireless charging mat and let it boot to emergency recovery screen
2) Load TWRP into AP slot of Odin and leave the window open on your computer ready to flash
3) Connect phone to computer whilst it's on the mat and press start in Odin as soon as your device appears
It may fail a few times but if your quick you can install TWRP.
4) Now boot into recovery and let your phone charge to a reasonable level (above 20%)
5) Boot into Download mode and flash your desired rim via Odin

Samsung sm-t580 infinity boot problem

I'm having this problem on my samsung tab sm-t580, it's in an infinite loop as you can see in the video. I can only enter donwload mode if I have the tablet connected to the computer and if I disconnect the cable the tablet shuts down, every time I tried to install twrp through odin it always gave me an error and I couldn't. Someone can help me?

Well it looks to me like you've destroyed your partitions or partition info, probably when trying to flash TWRP. It was probably for a different model. If you can get to download mode you have a chance. If you cant get to download mode:
Press and hold “Home + Power + Volume down” buttons for a few seconds until you see a warning screen.
Press Volume Up on the warning screen to accept it and boot into Download mode.
Also, I'd stop trying to flash TWRP. I think that's your problem. Since it seems you can get to download mode while connected to the computer, stay there and flash your stock ROM first. Be sure to use the Odin Re-Partition option since I believe your partitons are messed up (see the attached picture), it wont hurt anything as you're going to re-flash your OEM firmware. That should restore your booting to normal. Then, as I mentioned, find the correct TWRP, one that has been confirmed by more than one person to work with your T-580. Make sure that you can reboot several times to the stock ROM and then try get to recovery from the buttons or adp.
I am building some 30 pin JIGs that are designed to force download mode immediately after power is turned on. These are widely available, or used to be, for the micro USB port on other Samsung Android devices, but I haven't found any for the 30 pin connector so I am making my own. These will be available by the end of October 2021 on eBay once I confirm they are working as expected.
Good luck!
