Hi Guys,
I'm on a budget so I picked up an android off Craigslist today. Here is my problem -
Samsung S3 Rooted
Phone was working fine until I went into TWRP and wiped everything I could, and formated the phone. Obviously, I don't know exactly what I did.
Immediate problem -
Phone is stuck on boot, and I can't get into Fastboot, or a safe mode.
When I reset the phone, (by holding Power), the phone vibrates, shows a battery cell, then gets stuck on the boot screen. I guess this guy was using KToonsez KT747 - Kernel Dominaton, because that's what it says when I boot up. Then it just gets stuck there.
If I reset the phone and hold VolUp/Home/Pwr, it just gets stuck in a loop where it just vibrates over and over.
If I reset the phone and hold VolDn/Home/Pwr, I get the following -
Warning
A custom OS can cause critical problems ... ...If you want to download a custom OS press the volume up key. Otherwise, press the volume down key to cancel. If I press the VolDn key, it reboots and get stuck at the boot screen where it shows KToonsez KT747 - Kernel Dominaton. If I press the VolUp key, it gets stuck at Downloading... Do not turn off target !!
In the top left it shows the following...
Product name: SGH-T999N
Custom Binary Download: Yes (4 counts)
Current Binary: Custom
System Status: None
Qualcom Secureboot: Enable
Warranty Bit: 1
Bootloader AP SWREV:1
WHAT. DO.
Suggestions anyone?
Thank you,
Nate
If you have a PC you could go back to download mode and restore the stock software and see if that fixes the issue. If it does you could use download mode and Odin to reinstall Twrp and start flashing roms.
Download the latest ROM for the phone from here (it's slow so be patient): http://www.sammobile.com/firmwares/database/SGH-T999N/ . Unzip the file once to get a tar.md5 file.
Download Odin 3.07 from here: https://www.google.ca/url?sa=t&rct=...5QWImOPDJboTA_V3D5S9eA&bvm=bv.131783435,d.amc
Samsung USB drivers: http://www.samsung.com/us/support/owners/product/SGH-T999NBATMB
Install the Samsung drivers.
Open Odin, uncheck everythign except f reset time.
Click on PDA and select the tar.md5 file you unzipped.
Boot phone into download mode by pressing home, volume down, and power, then volume up.
Connect the phone to the computer using the original Samsung USB cable and the phone should show up as a COM port.
Flash the phone by clicking on start.
When you see the word "reset" in the status window, remove the USB cable from the phone, remove the battery, replace the battery, boot into recovery by holding down the home, volume up, and power button.
Perform a factory reset/wipe and reboot.
Hi there. After (an attempt) to unlock the bootloader of my A50 and installing TWRP Recovery (TWRP_A50_Magisk_Prepatched) i find myself in an orange bootstate. I can't get it into recovery, download or fastboot mode. It seems like a full brick. I can't even power off the device. Only Volume up, Volume down and Power button let's the device reboot but then the same boot problems appear. Is there anything i can do to recover my phone?
Text of first screen when booting up:
"The phone's bootloader is unlocked and it's software integrity can't be verified. Andy data on this phone may be vulnerable to attackers. Don't store any important or sensitive information on this phone". Press power key to continue"
Text of second screen when booting up:
"The phone is not running Samsung's official software. You may have problems with features or security and you won't be able to install software updates"
Any ideas!?

Try connecting your phone to your PC with the USB Type C cable, and do VolDown + Power to reboot the phone, and the moment the screen turns black, press VolUp + VolDown. It'll bring you to a different screen where you can press VolUp to go into download mode for flashing the stock firmware via Odin. I got my stock firmware from https://samfrew.com/all/page/2/#t (you'll need to search for your Model Number - SM-A505F/SM-A505FN/SM-A505FM, and select the correct Region. Also, select the correct Modem Version (the last 4 letters/number of the item to download). Then, follow the "Flashing Guide" at the bottom of the Samfrew page where you downloaded your firmware.

I had the same problem and managed to get back to the Download Page.
How do I find out what is the correct region of the correct Modem Version of my phone? It's an S10 (intl unlocked) that I bought in the US from Amazon.

You can find answers in the S10 forum. But I think the steps will be the same (this is A8 device/forum).

No bother. Hope you are sorted by now.
this is the exact same problem that goes for me with my samsung a505gn, i flashed a twrp 3.3.1-2_zvox and im stuck at this state. i found my stock firmware at the link provided above, but there are multiple types of a505gn stock firmware (XTC, SMA, GLB), question is, how do i know the correct type of stock firmware to reinstall to my phone, hence, having a limited information of the phone because of this problem (which is stuck at orange bootstate).

Have you got the a21s? As can't root it, as every twrp source I use soft bricks the phone, or just bootloops, or goes into error at boot up and stops half way. Was thinking trying other custom recovery. Any tips m8?

I HAD the same issue an I resolved it.
There are 2 methods to overcome this problem.
I even wrote a PDF and attached here in this post.
Below is SOME content from the PDF so it could be easy for users to find it on Google. I still strongly recommend you to refer to the PDF attached as it has pictures as well.
Samsung Galaxy M31 / Samsung M31 Screen is stuck on the following error message / error screen:
‘This phone’s bootloader is unlocked and the software integrity can’t be verified. Any data on this phone may be vulnerable to attackers. Don’t store any important or sensitive information on the phone.’
‘The phone is not running Samsung’s official software. You may have problems with features or security. And you won’t be able to install software updates.’ (error screen looks like below):
I was using correct TWRP and I was on Android 11 One UI 3.1.
Just to experiment, I flashed wrong TWRP version which was meant for Android 10 while being on Android 11. And so this problem started. Stuck on the error screen. Phone will not power off or on. Could not even enter the bootloader screen. Nothing works whatever keys I press. The same screen comes up. When the phone goes off and the phone will not accept charging that mean even you it whole night connected to charger, phone will not be charged- the same error screen.
So, the battery was not charging (my battery was at 24% just before this tragedy happened. It was late night and I thought of waking up tomorrow and plug in charger for an hour thinking if its battery is quite charged then I will follow Fix Method 2).
I woke up next morning and the phone was off (Battery drained fully). To this I was happy thinking that I can now hold Volume + and Power key and connect USB cable to enter Bootloader. When I did that phone would enter bootloader and gets switched off automatically (remember the battery was drained completely, charger too failed to charge battery and phone is not drawing enough power from USB port to stay on bootloader. On bootloader screen the phone’s display is fully on so more power usage).
Now I knew that the USB port is not proving enough power so that the phone could remain On while in bootloader when I hold Volume + and Power key and connect USB cable to enter Bootloader. I know for sure that Fix Method 2 will fix this for sure but it’s quite tiring.
So I referred to my PC manual to figure out which USB port provides maximum power. I found the right port (refer pic below):
So now I figured out 5 Volts port and plugged the original white Samsung M31 USB cable into one (refer the pic below):
If you don’t know which USB Port is 5 Volts then I recommend you to try all the ports and try getting to bootloader screen.
So when the phone was off, I pressed and hold the Volume up and Volume down key and with other hand I connected USB cable and now the phone went in bootloader and then I quickly flashed the right TWRP. Disconnected the USB cable and put the phone to charge and now it was accepting charge. Phone was back into life.
So I resolved it by Fix Method 1 below:
Fix Method 1: On my PC, I located the 5 Volts USB port and plugged the original white Samsung M31 USB cable into one (refer the pic below):
Entered Bootloader screen.
How to enter bootloader screen:
Assuming your phone is unlocked and the developers options are on and you have enabled USB debugging in Developer options and you have little knowledge of flashing firmware or TWRP via Odin.
Press and hold Volume Up and Volume down keys together with one hand and using other hand, connect USB cable to phone and release all the keys. Now phone will show bootloader screen which looks like below pic:
I quickly flashed the correct TWRP via Odin:
Flashing TWRP:
· Make sure OEM Unlock is ON in developer settings;
· Turn off the phone;
· Press the volume down + volume up button whilst the phone is connected to a pc to boot in download mode;;
· Long press vol up then confirm you want to unlock bootloader (this is needed one time only);
* Please be aware all your data will be erased including internal storage and phone will reboot!!
· Let the phone boot normally, pass the setup and connect to internet (wireless or mobile data) in order to unlock RMM;
· Make sure OEM Unlock is ON in developer settings;
· Turn off the phone;
· Use Vol up + Power + usb cable plugged to a pc to start the phone in download mode, short press vol up to confirm you want to go to download mode;
* If by any chance you see RMM state=Prenormal or KG state=Prenormal, factory reset data and redo from step 5!
TWRP screen was up. I tapped on Reboot and it did not reboot because the battery was not enough charged however I saw that TWRP Menu this means TWRP was working so the phone will boot up once it is charged.
Now I plugged in charger and was happy to see the correct charging screen (refer below pic):
I would turn power switch Off and On it quicky to know the charging percentage.
When it reached 20% I started phone (obviously by long pressing power key and it booted up just fine).
I loved myself
Fix Method 2:
Remove the phone’s back cover.
Be careful while removing the back case as you could screw the finger print sensor.
Disconnect the battery connector from motherboard and reconnect it.
Do not turn on the phone. As turning On will again get you back to the same error screen.
Put the back cover on.
Connect charger. Do not turn phone On yet. Wait for 5 min.
Do not even touch the phone.
Now you need to know the percentage of charge so do not hit the power button yet instead locate the main switch to which your charger is connected. Quickly turn Off and On and look at phone it shows charging percentage.
Once charging percentage reached around 20% you can touch your phone and power it on and it should boot up fine. It should not take more than 5 min to boot up.

Hi, friend. I have the same problem. But I don't even have a bootloader. When I log in, I just get a black screen.
Couple questions
I just picked up a SM-G960F/DS for experimenting with and am wondering about rooting it. I haven't put a SIM in it yet. Can it be used without a SIM card? I don't plan on using it as a phone just connecting it to Wi-Fi and experimenting with it. I am not sure what firmware to put on it. It came with BUILD R16NW.G960FXXU1BRF8. I live in Canada and I am not sure which firmware to download for it.
As far as rooting goes does it need a SIM in it to do any of this? Can i just add my Google account to get my Apps on it after rooting?
I have not rooted anything since my S6 and searched a bit and think this is the steps to root the S9.
I think that I should first be on latest Firmware before starting this?
Steps as I found info on process to get Root
got Odin3_v3.14.1.zip on PC and USB drivers - my SM-G960W connects okay
1 enable OEM unlock on phone
Downloaded twrp-3.3.1-1-starlte.img for S9 to PC
Use Bixby Key+Volume Down+Power to enter Download Mode and connect the device to PC USB
2 Open Odin and un-tick auto reboot in "options" tab, make sure that device is detected, Put twrp-3.3.1-1-starlte.img file into AP tab, Click Start
3 When Odin shows "PASS", disconnect the usb cable and press simultaneously the "Bixby key" + "Vol. Down" + "Power" buttons until the download mode disappears
At the precise moment the screen becomes black, immediately release the "Vol.Down" button and press the "Bixby key" + "Vol. UP" + "Power" buttons during 10 to 15sec to forcefully enter TWRP recovery
4 in TWRP swipe "Allow modifications"
5 Go into Wipe menu and select "Format data"
6 Reboot into TWRP recovery again, swipe to "Allow modification" connect phone to PC again Put RMM-State_Bypass.zip and no-verity-opt-encrypt-6.1.zip zips into external sdcard (or does this get done all in step 5?)
7 Flash RMM-State_Bypass.zip
8 Flash no-verity-opt-encrypt-6.1 zip
9 Reboot the phone into system Setup Google account.
now it gets confusing as to what to do for root...
So any help?
I imagine that the first thing I need to figure out is what firmware to download for it.
Hi folks
Anyone seen this issue before (see pic) ?
When I try to enter download / bootloader mode I get stuck on red text 'entering fastboot mode... ".
Odin cannot detect the phone connected to PC
The only way out is to press and hold power and volume down for 5 seconds to reboot normally
Tried factory reset and also tried clear data & clear cache partitions in recovery mode.
FYI I'm on O2 UK branded July 2020 stock firmware
With this steps the problem will be solved:
Power Off
Insert cable on pc
Press Vol Up + Vol Down
Insert cable on phone without releasing the buttons
But I agree, the 'old' method does not work anymore, I am getting the same message as the OP.

Amazing worked first time ! Thanks
Is this a very recent change by Samsung? I ran various Google searches but could not find any relevant article on the web or on xda forums
Hello.
Following the Magisk installation guide here (and cross checking with other source), once I have unlocked the Bootloader via OEM unlocking in the developer options, I still need to restart the device in download mode and long hold the volume up key. Looking at some bootloader another Samsung bootloader unlocking guide, it seems that there should be a warning screen where I can press volume up to "Continue" (into download mode), long press volume up for "Device unlock mode" (i.e. unlock bootloader) or volume down to cancel and restart the phone.
However, in my case, there is no long press volume up options, and if I try to long press, it would just register the volume up press and directly send me to download mode.
Perhaps as a result, the OEM unlocking option is never "Greyed out" (it does say Bootloader is already unlocked though).
Is this normal on the Tab S4? Does the VaultKeeper service exist in the Tab S4?
(I am on Android 10, March 2021 security update)
Thanks.
It should be unlocked, I am not sure.
If you flash twrp, PLEASE Disable auto reboot in the Odin options tab.
我也是这种情况。降级时提示bl没有解锁，但我已经解锁了oem并重启提示bl已经解锁。如果你成功了，给我看看
