SM-J120G screen blacks out while flashing stock firmware - General Questions and Answers

Hello, my phone was rooted with Magisk for about a year now. Today, the battery died while I was watching a video on youtube, and the phone shut down. When I tried to charge it, the screen woke up with red text on top saying "Custom binary blocked by FRP lock" and it kept showing this in a loop. The screen wakes up with the text, and blacks out. then again wakes up.
I tried Googling, and the solution I saw everywhere was to flash the stock firmware. I had done this once before, so
I downloaded ODIN, and then firmware from here (https://updato.com/download-samsung.../sl/sm-j120g/06975F2714E911E7963AFA163EE8F90B).
It was one .md5 file, so I put it in the AP slot and started.
Halfway through, the phone's screen blacked out and quickly came back in, but Odin said the process Failed, and the phone showed the following message.
"An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software"

Now, it is stuck on the above message. It is not like the normal download mode, but I can still flash the firmware through Odin. But always, halfway through, it gives the same error. The screen blackens, then quickly wakes up (takes like one second). Also, the phone doesn't seem to be charging, as when I disconnect it from the PC, it turns off completely.
My guess is, as the phone doesn't charge, it is an issue with the battery being dead.
I tried the smart switch app, but it doesn't recognize the phone.
The device is Samsung Galaxy J1 (2016) SM-J120G.
It has TWRP installed, but I can't access it now.
Rooted with Magisk.
Please help, I am a complete noob on this subject.

try it with a different cable, fresh download of the firmware, different computer or just try it several times in a row. itll likely work with a combination of some of those aforementioned methods. also could be the batt is too dead

Hello, I tried everything except downloading the firmware again, coz my internet is too slow. Also, I think the issue is with the phone.
First I connected the phone to the charger and left it to charge for more than 4 hours, but it still turns black randomly. So, either it is not being charged, or it's not a battery issue. Also, I tried with my brother's PC, and with another cable but the same result.
I think the device automatically reboots. When the screen goes black, it disconnects from the PC which results in failure. This happens even when not connected to a PC.
So basically, I am stuck on that error message. Once in a while, the screen turns black. Because it turns black before the flashing process is finished, it always fails.
Can you guess why the screen turns black randomly?
Thanks.

You get the Android's Black Screen Of Death because Android OS couldn't get loaded properly.
My recommendation: Re-flash Stock ROM.

But.. that's what I am trying to do. Odin fails to flash the ROM because the screen turns black.

you very well might have a corrupted DL of the FW. Get Samfirm and download the FW with that. Its literally 4 to 5x faster than directly from sammobile.com/firmwares

phone bricked i think

ok so out of no where my phone started flashing the boot screen i tried to odin it but it failed and it is now flashing a phone and a computer with a yellow warning sign in the middle how do i fix it if i can
also i cant get into recovery or download mode
You can still odin from the screen with the Yellow triangle on it. Try odin again, make sure that you put in the pit file, and that the odin package goes into the pda slot.
i cant odin it because the yellow triangle screen flashes so the phone is rebooting like every 5 seconds
The phone shouldn't reboot with the yellow triangle, are you sure you're holding down the trackpad and down vol buttons when turning on the phone (download mode)?
i cant turn the phone on as soon as i put the battery in the phone shows that screen and then 5 seconds later it goes off then 5 seconds comes back on ao so forth
Is this the screen you're seeing?

So by reading this, I assuming that Odin did recognize it before and then failed during the flash. You didn't unplug it before it was finished, right? It can take a while sometimes (and seem longer when something is kinda broken).
SD- Do you think his bootloader might have been corrupted somehow?
Try the Heimdell like SD suggests. Adam's stuff is great. If it fails, do it again, I have had to do it multiple times to get a phone right again (Guy I know flashed a wrong rom onto a different model phone with the wrong bootloaders-- hence using the heimell to load the correct ones onto it).
can i get a new bootloader then

There should be an option in Heimdall that you check for bootloaders. IF it is diminshed at first, run heimdall normally, and when it fails, it should be selectable. If this doesn't work out, there is a possibility of a hardware issue. If it works, make sure you hit thanks for Adam and SD for helping out...
my phone wont stay connected
any other help guys
If it won't stay connected long enough to flash in odin or heimdall then no, you have no other options.
thanks for trying guys
ok just found out my phone is hardware locked if it helps any of you guys

Help! my sm-n915t bricked

Hello all,
I have flashed ROMs via recovery and Odin plenty of times. I would say I generally know what I am doing and I flash ROMs on the regular. This is my third Samsung device and have been rooting/flashing for almost 3 years, so not a noob. And this is the first time I encounter problem with my phone while flashing ROM.
I was stuck in a bootloop on my Note and it wouldn't even let me boot into recovery, so I decided to Odin and back to stock and try again... I got the one-click, phone recognized, yellow COM box popped up, hit start, walked away for 10-15 minutes. Come back and there has barely been any progress at all... I could barely see the green progress bar. I figured something is wrong because I've done this before and it only takes a minute at most. What I did next is what I think messed me up...I pulled my phone and closed the Odin dialogue box and tried to redo it. Problem is, nothing I could do would get me the Yellow COM box. The phone goes into download mode but Odin doesn't seem to want to recognize it. I've tried EVERYTHING. When I boot the phone normally, I get the Samsung error screen saying there was an issue with a firmware upgrade and I should try Kies. I download Kies and attempt to upgrade firmware but my phone still not recognized. I already tried it to other PC still the same result.
I can't post the pic of my phone.
Is there nothing I can do to restore it?:crying::crying:

You sound like you have a problem similar to what I had.
I was downloading 6.01 to install using KIES 3 and got no recognition from my Windows 7 based computer when I connected up and ran KIES.
I had the Sammy 1.55.5 USB drivers installed.
What I did it was use KIES,not KIES 3.
Samsung says KIES 3 but that turned out to be wrong in my case,although I'm not sure why?
I'm now running M/M and happily gutting the bloat out of it.
It feels better than new now!
Solved
Anyway, I already solved it!

Help with apparently hard-bricked phone?

Tried 3 different versions of Odin, it always fails after boot.img ("complete write operation failed")
My phone model is G920I.
I'm stuck in the exclamation mark screen. Only thing I can do pressing buttons is reach the download screen. Can't access recovery.
Can I flash TWRP through odin and try installing a firmware stored in my ssd? Or that wouldn't even work seeing as I can't get pass the ! blue (green?) screen anyway?
Worst part is, I don't even know how this all started. I got a notification that a new update was released, but my battery was low, the phone died, I left ir charging and it wouldn't turn on the other day. I probably ****ed something up in the recovery screen (it was accessible in the beginning) and now I can only access the !/download screen.
Does anyone have any idea what I can do? Thanks in advance.

Charge you battery a bit anyway, to be sure there is minimum 30%. Then flash latest 7.0 firmware correctly for your model via Odin3 with latest drivers: https://forum.xda-developers.com/ga...official-stock-firmware-t3086387/post73935393 here you found all.

Made a new thread because my problem seems slightly different and I explain about it. Don't see how it could be prejudicial to the forum but thanks for the hint.
My phone is only on when connected with cable, either to the computer or charger, When I still had access to recovery mode, it said 99% battery. Now I don't even think I can check the battery? All I know is when the phone is not connected, it stays off.
I've tried using a couple of supposedly stock firmware from my model but the error is always the same. Gonna try downloading one from where you linked me to, but do you really thing it could make a difference, considering everything I've said?
Thanks in advance.

Worst case scenario ****up, need help badly :(

After 8 years of tinkering with Android phones I have no clue how this happened.
PIXEL 2 (Walleye, non-xl)
Tried getting TWRP and ElementalX working but either one or both weren't doing there thing, though I could at least boot and use my phone normally. Finally ended in a situation where I couldn't boot passed fastboot with an error at the bottom "ERROR: LoadImageAndAuth Failed: Load Error". Found a fix that said to change the active partition. Set it to b and that worked and surprise it loads TWRP...so somehow TWRP was installed, but I can't actually load Android.
Grabbed the latest factory image and manually flashed all the files in the zip-within-the-zip. Everything flashed with no hiccups so I rebooted to bootloader with the intention to then reboot the system, and now this is happening:
TLDR Phone won't turn on. Holding PWR+VolDown SEEMS to do nothing, but it actually flashes a line on the screen like it's trying to load something for a milisecond, then does nothing. Holding PWR+VolUp does nothing. Holding PWR+VolUp+VolDown does the same screen flash followed by the notification LED blinking red 2 or 3 times. Please help!
EDIT: if it matters, the phone is about 50% battery and currently still on judging purely by the fact that it's been warm for about an hour.
sorry for your troubles, i have yet to see this with our phones. Just to get some more information, what happens when you try and charge it? If you plug your phone in to a computer via USB, does it show up in devices? If it shows in devices, can you run platform-tools and see if it shows up via fastboot devices with an ID? If you can connect to fastboot, you could attempt to flash images that way.

Nothing happens if I plug into the computer, no sound and not listed in devices. Plugging it in to the charger does nothing except possibly charges it, but I wouldn't know because the screen doesn't seem to be able to turn on for more than a milisecond of a flash.
I had this same problem when I flashed Elemental X kernel over top of the flash kernel and all I did was use the flash-all script that is included with the system image from google. This got me back to my OS where I flashed elemental and magisk. Do you have insurance through your provider?

How to fix bootloop (can't boot into recovery or system)?

My Galaxy S7 (SM-G930R4) has decided to not want to boot. I can't boot normally or into recovery. I can only boot into Odin mode.
I've tried to flash stock rom, but it doesn't seem to work. I've heard that I should use the ROM from samsmobile, so I'll try that next.
This all started to happen after I accidentally turned on the phone right before I took the battery out. I put that battery back in and it booted fine, but after a few minutes it rebooted and started to reboot over and over again. It won't even show the charging screen when it is turned off and plugged in.
OK, I tried to flash the stock rom with Odin, but it still is in a boot loop. I've flashed it 3 times. I've firmware files from different sites. It seems that this S7 is dead. Please help!
Try to flash another rom and keep in mind that it sometimes takes up to 10-15 minutes at the first boot.
You could also just flash TWRP...

TWRP for the Samsung Galaxy S7 (SM-G930R4)???
Also, now I've been greeted with the screen that says "An error has occurred while updating the device software." It says to use the Samsung Smart Switch PC software to fix it. Hopefully that works.
Where are you?
What firmware are you using? Branded or unbranded?
Have you looked on Sammobile for the correct firmware?
Are you able to boot into system recovery? Home+VOLUME UP+Power (Not Download)?
Oh you have got the G930R4. I thought G930F.
Then I don't know if there is a TWRP you could flash.
But if there is one you could just flash it and enter recovery mode and install a new ROM from within the TWRP environment.
Check this out.

Sounds like your device is currently bricked anyways, so just give it a try.
Maybe you can get a working TWRP recovery mode again.

I am in the US.
I'm on Android 8.0 (Oreo)
I have a US Cellular Branded phone.
As soon as the phone is turned on, it tries to boot into recovery, but it can't so it keeps on trying over and over again. I've tried the firmware from SamMobile, but nothing seems to work.
When I flash to Stock ROM, and I turn the phone on, it stays in a bootloop of the "Recovery Booting..." screen.
When I flash the rooted Engineering rom, and I turn the phone on, it stays in a bootloop of the Samsung S7 logo. I can't boot into safe mode.
I tried to use Samsung Kies... didn't work... I tried to use Samsung Smart Switch... didn't work... I've tried 3 or 4 different ROMs from different websites.... didn't work.
i have the same problem. was able to enter download mode several times, but at some point it died completely (not charging anymore). how do you manage to take the battery out? does the SM-G930R4 the possibility to easily remove it?

The glass panel on the back is glued onto the phone. If you remove the glass, there are screws and from there, it's easy. I broke the glass in the process... so yay me.
Mine won't charge either. It is completely dead, but it will still turn on when I plug it into my computer.
Really strange. Mine is not turning on, even tried several locations, charger, etc. Once I had download mode while having a black screen. Keep an eye on odin and instantly flash firmware if it got recognized. I press all three buttons while plugging in; that's how it worked the first time for me....
