[Q] Power reset or Unknown Upload Mode

Hi guys,
I just bought my S4 i9500 and I think that came already as a brick. First time that I turned on the phone, loads in "Factory Mode". All functions were disabled and I can't use it at all. I tried removing the battery, turn on, turn off, with the sim card, without the sim card. Always starts in "Factory Mode".
Then I decided to make a Hardware reset, but when I press (Vol Up, Home, Power) appears "Power reset or Unknown Upload Mode" instead of Recovery Stock. (Attached a photo)

"lightbox_download": "Download",

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Then I thought, "Ok, I will flash with Odin the Firmware Stock of my carrier".
After that, the Factory Mode disappeared, but during the Setup Wizard, appears a pop up with "Unfortunately, the process android.process.acore has stopped." and I can't never finish the wizard.
For my surprise, when I tried to make a Hardware reset, the recovery mode is still failing. Instead of that, appears "Power reset or Unknown Upload Mode".
I don't want to touch so much, because I'll go back the phone to my carrier trying to get a new one, but they don't have stock right now.
Any clue? I'll really appreciate it.
Thanks in advance!

Looks like your phone came with a bad firmware install.
You may should replace it.
Did you not turn it on at the store ?

They sent the phone via post. I flashed the branded firmware, but it's not fixed.

Contact your suppliers.
Dont tell them you flashed anything.
This is obviously a phone that needs to be changed. Let the sellers figure out how to fix it.

My i9500 has this problem too. When I first open the phone from box it was in Safe Mode. Then I restart and it's normal. But everytjme I try to put my phone into recovery mode (Power + Home + Up Volume) I get this screen first, I press the combo again and it goes into recovery. I rooted the phone and install Omega Tom, everything works just fine.

just re install the firmware, it happend to me with a sony x10a, i just plug the phone and choose re install firm, but maybe you should use odin

Which Recovery Stock or Custom (TWRP/CWM) ??? Any Explained Scenario what exactly you did???
Your Device N910F or N910C???
If Your Device doesn't properly start...
First Try through Samsung Kies Recovery if yours Official....
Other Option is to Download & Flash Appropriate Firmware For Your Device....

Ignore that message. Click on firmware initialisation and put in your serial number and whatever else it asks for and let Kies do its thing.

[Q] Help / Stuck [D800] - Can't get computers to see phone in Download Mode

I've probably used the LG Flash Tool 10 times the past week on both my home and work computer with no problems. Last night I flashed the KK bootloader and a stock 5.0.2 ROM (after tot'ing back to 4.4.2, rooting, etc).
It hangs at the LG logo and that's where I'm stuck. I tried going into Download Mode, but suddenly both of my computers won't see the phone and give me an error in Device Manager. I've tried uninstalling / reinstalling the drivers as well. Why in the world would that happen unless somehow Download Mode was corrupted, possibly? But it goes into Download Mode fine, and appears to look right...
I've tried getting into recovery but can't. When it should load up TWRP (after telling the G2's "stock" recovery screen I do want to reset), I get the green spinning Android (not the red exclamation) for a second, then it tries to boot up.

"lightbox_toggle_sidebar": "Toggle sidebar"
}
Any advice would be appreciated as I've never run into this before.

So when the green Android popped up, I tried to hit a combination of the volume and power keys and WAS able to get into recovery. Unfortunately, it appears, somehow, TWRP was overwritten by the stock recovery. I have no idea how that could've happened. Or does stock recovery technically stay in place since this is "loki'd" and not actually unlocked? And if so, is there some way to get back to TWRP that I'm unaware of?

To add to the weirdness, when I plug it in to charge, it doesn't pull up the battery like it usually does when powered off, it just tries to boot up again...
If I could just get the computers to recognize it again...

Installing the LG PC Suite got my drivers to a point where it could recognize it while in Download Mode. MTP still didn't work, but that didn't matter for Download Mode. Not sure what happened, but at least I was able to flash it back again.

Unable to access Download/Recovery Mode after bad flash

So my brother in-law decided to try flashing a ROM onto his Galaxy S7 SM-G930 but somehow managed to flash a ROM meant for the Galaxy S7 Edge SM-G935. Needless to say this resulted in some serious issues. He tasked me with trying to fix his mess, but so far I am at a loss. Here is what I have tried to get the proper firmware back onto the device:
Galaxy S7 Recovery = No worky
* Tried Vol Down + Home + Power
- Results in some kind of diagnostics menu that is in Chinese or something
- Managed to get phone to go to fast boot from here, which has at least aloud the phone to boot and have a useable interface.

Galaxy S7 Edge Recovery = No Worky
* Pressing Vol Up + Home + Power
- Results in option to Select Boot Mode (YAY!!! Right? ....Maybe not)
- I select recovery Mode and it freezes for a couple minutes, then reboots the phone without enter recovery mode.
Basically I am not seeing a way for me to get to the point where Odin is helpful. Does anybody have any other options or suggestions I could try?

Have you tried to see if adb works on any of those modes? If it does try to adb reboot bootloader

adb not working either

I did try adb after making my post yesterday. I was able to connect to it fine, and was able to use adb reboot bootloader which gets me to fastboot. Nearly everything I did there didn't give me good results. Including fastboot reboot emergency which results in the phone restarting normally.
Also doing adb reboot recovery results in normal restart after pausing at all black screen for 1-2 minutes.

Did you try to flash a stock image via Odin after you ran the adb reboot bootloader?

Odin doesn't see the phone :|

Looks like a fake galaxy, I can be wrong

You know, I suspected that when I first saw the diagnostics screen all in a foreign language. After digging into it and checking the firmware and comparing to iFixit's teardown of an S7, I am leaning heavily toward this being a knock off device.

S8 bricked / stuck in recovery mode, what did I do?

Hi,
first of all: I'm a noob and I've got no idea what I did. I appreciate all of your help to get my phone back alive!
My phone (Samsung Galaxy S8, SM-G950F, stock ROM, Android 9.0, not rooted or anything else) is stuck in recovery mode. It doesn't react to any buttons (e.g. very-long-press power button) or connecting a USB cable, also my PC and Odin with all drivers installed won't recognise the device.
What I did: I went into download mode to check if I could find my RMM status (I didn't) and navigated to "view recovery logs". I entered /cache/recovery/last_log and scrolled through it until I reached "back". I confirmed with the power button and - then I can't really remember what was there on the screen - I got into a similar log screen. It took a while and I pressed the Vol-down key quickly numerous times.
Then it happened: there was a screen with some options to choose from (written in blue) but spamming the button I probably entered something. Another log (or whatever) showed up --> see photos. It took about 20-30 minutes to reach 100% and then went back to the Android recovery screen, where it's been stuck for about an hour now. I tried cancelling it numerous times times with long-pressing power button, but nothing happened.

PLEASE help, is there anything I can do besides waiting for the battery to die and reboot?
Big thanks in advance!

Note: the device has been factory reset recently with no data on it, OEM unlocking and USB debugging were checked in developer options as I was about to flash TWRP.

1)Download stock firmware from sammobile or else (exact your device and model)
2) Download Odin
3)See video on youtube if noob(obviously ) to flash stock by going to download mode
After successful installation u will have your cell back
Cheers......

Thanks for the advice, but I found that pressing Power + Volume Down for 20+ sec. could eventually shut down the phone. After that it rebooted into recovery mode, even though it took ages.
Now I'm a happy owner of a LineageOS S8 btw
Entering download mode wouldn't have been possible at the stage I described in my first post, as the device didn't react to anything at all.
