[HELP] Prototype EK-GC100 bricked...

So I got an interesting device online - a prototype Galaxy Camera (EK-GC100). Only 2 hours ago I received this baby which looks very different from the production model, and more importantly, has a software build that's pre-production: GC100ZCALH1 (Android 4.1.1). All existing ROMs on the web dates back to LJ5 and LH1 is even earlier than that.
Problem is, I recklessly thought that this prototype should be able to use a firmware from a production model, and without second thought flashed a later firmware on it (XXBMC3 - Android 4.1.2). The device boots up, but the screen immediately goes wild at the "Galaxy Camera EK-GC100" splash screen for some brief seconds, and then the screen blacks out. I can hear booting sounds. On very rare occasions the screen would light up saying "Encrytion unsuccessful", asking me to do a factory reset, but clicking on the button simply reboots the device.
I attempted to boot into recovery (both stock and CWM), but after the screen goes wild and shuts down, I can see nothing so I can't operate even if the recovery actually works.
I am currently experimenting with different firmwares in Odin but I doubt that would help. What can I do as of now? Thanks for any tips. I don't want it to be a $60 paperweight...

System Software not authorized by AT&T has been found on your phone...

My husband's phone has this message on it and he has not downloaded any software. He owns the Samsung Galaxy S5. He went to the AT&T store where we purchased it and they said he had to go to a Samsung dealer - Best Buy. He went there and the dealer had never heard of the problem. He reinstalled the operating system, but we still have the same message.
Husband took it to Best Buy and they did the reset - it did not help. He went into the AT&T Device Support Center on Barbur Blvd. in Portland - they took it in the back, brought it back, it showed a screen and they were able to do a little. He got home and you have to hold both the volume key and the start key in order to get it to open. It then freezes and you can't do anything. I have tried the factory reset, started to do the set-up, and it is freezing again.
The last thing I tried was to try and get KIES to recognize his phone. After that, he was able to turn it on - it goes through the Samsung opening. Then it freezes. Sometimes it opens to the apps and he is able to try to make a phone call, but it freezes.
Help!!

I would file a request/complaint with AT&T customer service and ask them to replace the phone w/o charge since Samsung couldnt solve the problem and from the sounds of it made it worse than before.

The only time i have heard of that message coming up is if a custom recovery was flashed to the phone. Since the bootloader is locked, it will freak out like that. Could maybe try using odin to flash the original firmware and recovery? Not sure where this file would be available for download right off hand.

Self Restart

I have got my Asus ROG Phone II for about 8 months and I have recently got some problems with the software. The phone suddenly turns off on it's own, when I am using it and stucks at the restarting process with Asus Logo and the loading bar on the lower side but doesn't open, even if I wait for a full whole hour. I have to press volume down + power off button to make it work again. I wanted to ask if any of you guys have got the same problem, or any clues how to solve it?
Well I had rooted my phone after a month of it's use and unrooted it. For about 2 Months before, my charging port stopped working and Asus Service Center fixed it, and I guess they somehow flashed my Phone, as I not don't have to download and install the new firmware. It was good in a way but I feel it is getting some lag during the use of certain apps and the problem which I mentioned earlier. I would be thankful and grateful for your replies.

Don't know what the problem is, but you've posted this in the wrong section!

I think I am in a similar situation. My phone's problem is that it kind of crash while booting up (stange lines shows on the screen like some glitch) , it doesnt boot up normally and it loops 3 to 4 times until it's left on a black screen. I am not sure of its status at this point for it is not responsive even to force restart (Vol down + Power) but it does work only once in a couple of minutes and proceeds to bootloop and back again to the black screen. I haven't rooted it but i did flash it from CN to WW which was successful and was using it perfectly for 4 months up until this situation. I dont know what exactly is the problem. Can anyone help me?

Same with me bro... Mines already bricked because of flashing it to the original version

Samsung GT-N7000 - The screen goes black after the startup logo

Hi,
A few days ago, I replaced a USB socket on friend's old Samsung Note 1 (GT-N7000). Soldering may not be very professional, but it does the job - the phone is charging and it can connect to the computer.
Today (3 days after replacing the USB) he came back to me with another problem -
after turning on the phone, only the white brand name and model appear at the start and then nothing, a black screen. I think it's turning off. He says he had some problems with the battery in the meantime and the screen was flickering strangely.
He had a custom ROM loaded for a long time that worked normally and worked well on this phone.
Today, despite not starting the system, I was able to enter TWRP recovery and DL mode. However, if I wanted to do anything in recovery (backup, factory reset, etc), the screen turned off. After a few attempts, it stopped going into recovery.
I have restored the original software using Odin and N7000XXLSZ_OXELS7_4.1.2_Repair_Firmware
- still after the white inscriptions at the start, the screen goes black and nothing
- trying to enter recovery, overturned android appears for a moment and the screen goes black
- DL mode works
Maybe someone knows what could have happened and most importantly how to get this phone work? Preferably on some "custom ROM" to have at least Android 7.

I was thinking, I was looking, I was tearing my hair out of my head. I searched half the internet and suddenly stumbled upon this - https://forum.xda-developers.com/t/...bricked-only-download-mode-available.3096409/
The phone is the same, the problem is the same - the battery is to blame. I immediately called the owner to give all the batteries he has.
OH, OF COURSE! The one I got along with the phone and its problems was the only one that caused all the restarts and errors. After inserting a different battery, the problems were resolved.
All that's left is to clean up Android and the case is closed.
By the way - I have collected in one place the files and information (Polish language only) on how to install NightOwl LineageOS 14.1 Android 7.1.
2 on this phone. If anyone needs this information, please visit here - https://drive.google.com/drive/folders/1libYpWC4qJbjGJRE1Szf8L3eTdoHPTpE?usp=sharing

S20FE TMobile black screen

Got up this morning to a black screen. At first power + down volume would show the Samsung boot screen, but it would never fully boot. One time it did make it to the the home screen but froze almost immediately. After that it has only showed the Samsung boot screen a few times while holding down power + down volume. I have tried tried power + down volume or up volume several times now and can never get it to show anything any more. The phone should also have power as it has been charging all day. After doing some reading I was going to flash it with Odin, but it only shows up as QUSB_BULK_CID... and Odin doesn't see it. This is after installing Samsung USB drivers v1.7.59. Is there anything else I can do?

hello colleague
Reading this post makes me think about making periodic backups.
since I also have an S20 FE 5g TMO.
I hope I have a solution to the problem.
but apparently I think it will be hardware problems.
I have investigated and there is also a publication of an s20 with the same problem.
greetings

Can you point me to the S20 with the same problem? I really hope it isn't a design issue with the hardware as I have 3 other S20FE's. All bought at the same time. The phones are only a few months past 1yr old. Would be nice if it is a software issue. Since I couldn't figure anything out with it, I dropped it off at a replace called ubreakifix by asurion. They were listed as a repair center on Samsung's website.

I got the phone back today. At first the shop said they couldn't reproduce the problem after I left it there. It was just slow to start up. Gave it back and didn't charge me anything. After I left I just started open and closing stuff. And the UI would freeze some, plus I would get System UI not responding and Process system isn't responding errors. I took it right back with the error. They were able to scan it again. This time there Samsung software said it had corrupt memory. They said the board would need to be replaced and that would cost what a new phone would cost. So, I just ordered a refurb S20FE from Back Market. I am still going to try and wipe and flash it. But, I don't know if I trust it now.

Just looked in the software update menu and noticed it updated the system on 2/7 at 12:10pm. The phone had the black screen on the morning uf 2/8. The alarm didn't go off at 6:00AM. So, it started acting up less than a day after the update. Coincidence?
