i was using some jelly bean sony rom by divaksh (it had cwm touch) and i wanted to try the new cm10.2 rom by munjeni
i downloaded the cm10.2, put it on my external sd card through a usb micro-sd reader and then put the µsd back in the phone
i selected "reboot to recovery" from the phone's power menu (i had an xposed module for more power menu options)
then i noticed that the phone didn't reboot, but it had turned off completely
i held the power button and the phone vibrated but didn't power on
it powered on on the second try, i then went to the cwm recovery by tapping the volume down key
(i was going to make a backup of the current system, but i forgot it lol)
i flashed the cm10.2 zip (cm10.2_pepper-ota-eng.root_Build.1.zip) without doing any wipes, because i wanted to get to the correct version of cwm recovery
(i would've properly done the wipes/formats from the cwm recovery that is in the cm10.2 kernel)
it finished flashing the zip and i rebooted my phone, but then it didn't power on anymore
now when i hold down the power button, the phone makes a short vibration but nothing else
.
if i plug the phone to a charger, the led lights up (red) for approximately a second and then turns off
if i hold down "volume-down" and the power button, the phone vibrates once and flashes the led (green)
i've tried going into flashmode and fastboot mode but the light doesn't stay on for long and sony mobile flasher doesn't even notice the phone even though the drivers are installed
the "hold down power button and vol-up"-thing also works but it doesn't seem to do anything else than vibrate
what should i do?
Is your bootloader unlocked?
If yes then flahs

what?
Is it unlocked?
When I bricked my xperia p I flashed a custom kernel which allowed me to enter Cwm and then flashed the stock rom. I am new to this flashing thing so I recommend that you ask someone experienced what to do. I just shared my experience of recovering from a softbrick. Don't flash new things blindly but ask someone experienced before doing so.

the bootloader is unlocked, and i'm not new to this "flashing thing"
anyone? the phone still hasn't woken up
download firmware for your p and flash using flashtool...

Have you used flashtool to flash firmware before on that PC?
Have you installed flashtool and it's drivers (sola, flash & fastboot mode).?
Make sure the phobe is off, press power + volume up untill you feel 1 + 3 vibrations and see if it stay in flash mode longer.
Just Flash stock
i have nearly the same problem
my xperia u was running with 4.1 then i restored my ta backup its mine not for someone else then i pressed reboot instead of power off then my phone is dead no vibration no led except the one when i plug it to charger just one red led then nothing

how? the phone doesn't boot and flashtool doesn't recognize it
Same problem here, I think that Munjeni's post is bad written.
Ok, I fixed it, follow my instructions as they goes. You have to flash the .img kernel that CM10.2.zip comes from.
For flashing it, go as follows...
First try to install the following drivers, with Flashtool. The executable is in C:\\Flashtool\drivers
Run as adminsitrator and follow screen instructions, allow any driver install.
When it's ready, try to plug in the phone in fastboot mode (turn off, hold power and vol up and release power button, led has to turn blue/violet/pink, whatever, a color like that)
Run flashtool.
Flashtool will recognize the phone as the log says, if its not try to install drivers mannually.
If it's recognized then click the black lightning button and select fast boot mode.
At the right side click "Select kernel to flash" and browse the kernel that comes in the .zip. (in the file you've downloaded you have to extract a boot.ini because is the main kernel to make the ROM work, so you have to put somewhere else, I prefer desktop)
When selected, log writes all the procedure until it show an "OKAY[time]" message.
Finally click "Reboot device into system" in the center side and wait until boots.
It should be working now, I spent a lot of hours investigating, but finally I fixed, hope it works for you too!
If there's an error or some question, feel free to post.

That was "the long run" for windows-guys.
For Linux - no drivers needed anyways - just download fastboot from anywhere and look for kernel. Put them in a personal directory. Open and run in a terminal (some have to be login as su) "fastboot flash boot kernel.img" (or whatever kernel is called...), plug phone in usb, while press and hold power and volume-up buttons. Blue LED comes shining and terminal tell you the flashing.
Unplug or type "fastboot reboot" to re-start phone.
Sure, you also can use FlashTool, too. But for only flashing a kernel it is not needed. Only for flashing stockrom ftf. But this is another story.
i happens to me yesterday
Hi ! Dont worry u r not the first to face this problem i also face this problem yesterday.. my phone was on JB 4.1.2 i download custom ICS rom and install it through CWM Recovery mode, when my new custom Rom starts it stucks on Boot screen and then nothing happens i tried but my phone was in danger... i was worried then i install flash tool and downlaod ICS Rom for Flastool and install that after severals trys i was now ion ICS v4.0.4..

If I wrote for Windows 8 there will be more than that, believe me. Managing Android with Linux is a lot easier, from flashing to programming.
But, face it, Windows is the standard here.

My Tab S6 tried to auto-install an update yesterday (it is rarely connected to Wifi/internet). It then rebooted. Since then, it's been stuck in a boot loop.
It will display the "Samsung Galaxy Tab S6 | Secured By Knox" logo screen for a few seconds, then switch to the blue "Installing System Update" screen (with the android logo). Installing System Update gets to 28% and stops. Then the rotating icon on the android freezes. Then the device reboots and starts all over again.
Edit: the tablet is 100% stock. It's not been rooted or had any custom ROMs loaded.
I have tried getting to recovery mode, by holding power+volup while it boots. This doesn't seem to change the behavior at all. Any advice is much appreciated.

can you shut it down? try volume down and power button ? if it don't shut down, do this soon as it reboots, hold volume up and down and plug in usb cable to desktop/laptop usb port! it will boot into download mode!

I can't actually shut it down. If I start holding power+voldown right after it boots, the tablet does reboot before getting stuck at 28%. But it reboots--it doesn't power off.
I tried download mode and that actually seemed to work! Specifically, I left the tablet overnight in the reboot loop until the battery drained. Just now, I held down volup+voldown and plugged it into my laptop. I got the green "Warning/Custom OS" screen and then pressed volup to continue. The tablet rebooted pretty quickly after that (I'm guessing due to low battery) so I didn't get a good look at the download mode options.
Once I'm in download mode, can I factory reset the tablet? I don't need to preserve any data/apps/settings.

You cannot reset the tablet from Download mode afaik- You need to enter Recovery Mode to do that.
You can however, flash stock from Download mode using Odin (3.13.3 is best). If you're not confident with doing that, your best option is Factory Reset in Recovery Mode. Hold Volume Up and Power when the Tablet is booting, let go when you see the Samsung logo. The timing can be tricky, but you should be able to do it. Also, you can force a reboot with Volume Down and Power.
Alternatively, if factory reset doesn't work, since you're completely stock, you will still be covered under warrenty.

Thanks for the suggestion. I have tried this many many times. I've tried letting go of the buttons at different times. I've tried holding volup while letting go of power. I've tried this a ton of different ways, and no matter what, the tablet always shows the "Installing system update" screen. Some googling has led me to believe that sometimes, when performing a factory reset, the "Installing system update" screen shows up right before the normal recovery screen. Is it possible that the tablet is trying to get to recovery mode, but can't get past this first step?

Honestly, I don't know - I'm not an expert but I guess it's possible that the update failed and corrupted both System and Recovery.
You'll be covered under warrenty, so maybe just return the Tablet from where you purchased or direct to Samsung, could take a while given the current situation though I guess. If you have a PC, then I think the best option would be to just flash stock yourself, since that's probably all Samsung will do. Even if that doesn't work you'd still be covered under warrenty, as far as I'm aware attempting to flash stock doesn't trip Knox.
Here is solution to unbrick your device!!!

Despair not...I have just come from resolving this exact situation not 30 minutes ago. I'd been trying to flash (using Odin as I decided to stay on Stock and not root this device, for a change) the latest OneUI2.1 releases for my device (SM-T865 - LTE version) and boom in the middle of the Odin update, the flash just failed...I then couldn't reboot and get into neither Recovery, nor Download Mode because it appears my bootloader and recovery both got corrupted.
Here's what you need....
1. Odin app for PC (am on Windows)
2. Your device's Stock firmware (sammobile firmware archive)
3. You will need someone to help you boot the device directly into Download mode (and this is the tricky part because for most of us we are used to get into Bootloader by using the key combination (from Powered Off device) Vol+ and Power On at the same time to get into stock recovery and then scrolling down to option 2 in this menu, "Reboot to Bootloader". Well now you are going to boot directly into Bootloader mode. Here's how you do it...
4. Get your friend to line up the USB-C cable into the port of the device, but DO NOT press it in...yet
5. Press Power off and Vol- buttons at the same time to turn off the device
6. And now you have to to be super fast: if device starts to turn on on its own, YOU press and hold Vol+ and Vol- both at the same time while YOUR FRIEND pushes the USB cable fully into the port - you should now have booted directly into Download mode. (if not repeat this, and remember to be super fast and sync with your friend pushing in the USB cable)...
7. When you get into Download mode, then you are home and dry...
8. Select ONLY the Bootloader file (BL...XX...) in Odin, make sure only "reset time" and "reboot" are ticked, and flash
9. When device reboots, press Vol+ and Power combo to get back into Bootloader mode again...but I think device will reboot into Download mode on its own
10. Now select all the files from your Stock file into the various tabs (BL, CP, CSC, AP...) do not select HOME_CSC as we want to flush this device clean...
11. Flash, and voila...success - you will have lost all your data but rather that than losing the device...
12. Feedback here and let us know if this works? For reference for others in the future...
FYI, I got in this situation, and the previous post did work for me, just takes good timing! Thanks!!!!
Same issue today for me. My tablet showed different screen with green and red text, it allowed me to delete app data, then booted into safe mode, then i had to do factory reset and now i am screwed, as it is refusing to restore any apps and their settings. I will try to flash it back to Android 9, maybe then it will do the restore. I forgot to do any manual backup to SD or so.
Edit: the device upgraded to 10, but reset itself after about 10 minutes of use.
Edit2: i found what caused it. It is caused by Nova Launcher, if i try to set wallpaper.
Just found a news article that there is a RGB/sRGB problem with wallpapers. It might be the problem i had.
I am adding a screenshot of the result.
Yeah, I had that kind of reboot loop from a wallpaper that I downloaded

Hi,
Really need your help, after I updated my firmware using Odin, updated BL, AP, CP, CSC, my tab cannot boot up stuck in logo. Doing the Power + volume up leads me to different screen now. I cannot access recovery mode or download page anymore,
What must I do? Pleasssee help. Added the pic, after doing hard reset (power + vol up)
I cannot connect back to Odin also. Always setup connection failed.
Please help. Really messed up big time
Just a thought... Can this be restored from service center?
Thank you in advance.
I have the same problem with a Tab S6 Lite, it is in bootloop and does not let me enter the recovery mode, I can go into download mode and I flashed the latest original firmware Android11, Android10 etc., . I tried them all but always goes in bootloop, and also the bootloop occurs only if I connect the usb cable to the PC, without any sign of life. Do I still have hopes or have I compromised the motherboard?
The reason for all this is because I had followed a guide to give root permissions with magisk, I did everything right, only that the guide was with Android10, while I had Android11 and I was deceived by the fact that in the title of the guide there was written "guide 2021"
, so I did not check the compatibility of operating systems, I was a fool, I know, I hope so much that I did nothing irretrievable, it's my son's tablet!

Download the android 11 last rooted rom from there. You install it with odin as as a normal original rom.
Disable in odin auto reboot. After rom install, restart manually and press the correct buttons immediately to boot in Twrp and not to system. Format (not wipe) data from there and reboot to system. If you are lucky it will work..
(I hope you unlocked bootloader before try to root. If you haven't unlocked bootloader this won't work also).

Download the android 11 last rooted rom from there. You install it with odin as as a normal original rom.
Disable in odin auto reboot. After rom install, restart manually and press the correct buttons immediately to boot in Twrp and not to system. Format (not wipe) data from there and reboot to system. If you are lucky it will work..
(I hope you unlocked bootloader before try to root. If you haven't unlocked bootloader this won't work also).

Same issue today for me. My tablet showed different screen with green and red text, it allowed me to delete app data, then booted into safe mode, then i had to do factory reset and now i am screwed, as it is refusing to restore any apps and their settings. I will try to flash it back to Android 9, maybe then it will do the restore. I forgot to do any manual backup to SD or so.
Edit: the device upgraded to 10, but reset itself after about 10 minutes of use.
Edit2: i found what caused it. It is caused by Nova Launcher, if i try to set wallpaper.

Wiping cache partition in Recovery and reflashing the firmware are basically your only 2 options

Flash in odin the same rom you had. There are 2 csc files in rom, which you use 1 in odin one. Try use the "home csc". Home csc keep KEEPS your data. If you're lucky it may work. (It would work in keeping your data 100% if your rom was ok. Because it isn't you have some changes to work.).
You must try with same rom or newer.
CSC – If you flash the CSC file, it’ll perform a factory reset of your Galaxy device and wipe all data while installing a new firmware to bring your device to the same state as it was when you purchased it. Go with CSC if you want a clean installation.
HOME_CSC – On the other hand, if you want to keep your Samsung phone’s data and settings even flashing the stock firmware, you can select the HOME_CSC file.
