I rooted my LG recently to get rid of the crapware that was on by default. But, of course, it wasn't enough for me. I tried to flash a new ROM, and everything went to hell. Now the boot screen won't go past the LG logo. Does anyone know how to reset the device back to factory standard?
Hard reset doesn't work (home + volume down / up + power)
Windows/Linux doesn't see the plugged in device.
adb doesn't see the plugged in phone
I tried to put cyanogenmod on, which was probably a bad idea. I've heard that this problem may be irreperable, and I just want to see if there's any way to avoid having to try and deal with Verizon.
Before flashing (using rom manager), I made sure to choose the backup the current rom option. I've heard that I should be able to restore that backup, but there's no way to actually connect to the phone at the moment.
Any help would be appreciated.
EDIT: I've gained access to the SD card by plugging it into an external reader. I can see the recovery image that clockwork made. How can I get the phone to boot into it?

Yes, please do post it. I attempted the LOL 1.4.2 rom for Optimus One and am now in this same situation. I have a working rom on my sd card if I could just get to the recovery screen.
[Solved!]

I read a few posts mentioning that they were able to reset their phone using their ac adapter, but I hadn't any luck trying it that way, until a good friend of mine used some google-fu to determine that the order in which you do things matters! Here's the steps I had to take:
Remove battery from phone
Begin holding power, volume down and home
Plug phone into ac power WITHOUT LETTING GO OF BUTTONS (wasn't easy for me either)
Phone should boot into recovery (in my case the custom recovery)
You can let go of those buttons now
Install battery
Flash your phone and rejoice!
THANK YOU! The part I wasn't getting was the plugging into A/C while holding the buttons down...you're a lifesaver!!!
This did not work for me. I tried putting the phone into recovery mode, but it still just booted up as normal. I'm running out of ideas and patience here...
Please use the Q&A Forum for questions Thanks
Moving to Q&A
Lgtools
estoy en la misma situacion, yo cuento lgtools de Setool Box3, la cual soporta lectura y escritura de sistema de Lg vortex vs660, pero no logro que me lo detecte para cargar firmware completo, mi problema fue que flashe el recovery desde el ROM MANAGER y se queda en el logo.
I recovered my friend's phone using the following procedure
I just fixed a friends phone so I thought I would share in case it helps anyone. This is for the LG Vortex on Verizon. Might work for other carriers.
Download and install the Vortex drivers from LG's mobile support site www dot lg dot com/us/support/mc-support/mobile-phone-support.jsp
Download and install the LG Mobile Update utility www dot lg dot com/us/support/mc-support/mobile-phone-support.jsp
Run the LG Update app and make sure your phone is up to date. You can also try the Recover option if it can't update. This phone's firmware was up to date.
Install the Android SDK from google.
Access backdoor recovery through ADB
Plug phone in to laptop usb
Press and hold down the volume down key, the home key, and the power key at the same time. Keep them pressed until the screen goes black then you can release. If it goes in to some other visible recovery you can simply skip some of these steps
At this point your computer should start to recognize the phone and go through a series of driver installs
Once that is complete you should be able to go to the command line and enter the ADB shell
Follow the procedure at the following link to get the clockworkmod recovery installed
androidforums dot com/getitnowmarketing/330813-all-one-recovery-thread.html
Once you are able to boot in to clockwork, immediately do a backup. Then clear your data, cache and dalvik cache, then reboot. This won't always work, but many times it will allow you to boot a ROM that gets stuck booting (like this phone). If that doesn't work then just go back to recovery and utilize a manual ROM flashing procedure you can find on many forums.
This process worked great on this phone so hopefully someone else may have similar luck.
Sorry for cutting up the links, i'm new to the forum. Just replace the "dot"s with . obviously.
Try this worked for me
Here's a different method of unbricking your vortex V660. With limited support and methods for this device it seems to make everything more complicated in finding a soluttion around certain but complex problems. I tried to use some of the other metheds listed on android central and XDA...such as, taking the battery out, holding home, vol -/+ and power key at the the same time the phone back in while it was connected to the computer. I wasnt able to get anywhere with these methodes,I also thought qbout trying the unbutu method to unbrick it then I thouht that was to much of an effott. I read all the comments and differnt methods and decide it wasn't worth the risk, I re-woked a different method for unbricking, there's prob about a 90% possibility of it working for your LG.This just happenes to be my own solution or workaround if you find yourself screwed like i did with no type of support.
The reason this didn't work was because I didn't have cwm installled nor did the phone have the original firmware installed, my mistake, I wiped that off too, happenes when you have to much to drink lol, the hard reset buttons were a no go as well since they take you into cwm or the orignal firware from verizon {all mine did was take me to a black screen because there was nothing there for it to load.} Some how or another all was wiped clean and I was in a catch 22 while being bricked. I found the vs660 recovery firmware but I knew i really didn't need to install it so i didn'nt.The bricked happened after I installed Titanium Backup then uninstalled launcher pro so then I restarted and got to the point where the ring Fire or boot animation was trying to load ,and it just just hung there. I don't care for the app launcher pro I would rather use awd launcher, if u haven't noticed you have to pay for the pro version of launcher pro just to rezize widets, so im wondering why this app was added to the Rom Cyan7.2 in the first place. So with no cwm, no stock image, and no way to make an sdcard boot into m to unbrick it my hopes and last resort were to pray that.I had usb debugging enabled.
First thing you have to install is called jdk-7u3-windows-i586] the other file called installer_r_windows wont't allow you to install until the install of JDK is complete.It'd ok to lauch the installer-r26-windows first because it ill drnf you directly to the site to downloadthe JDK file. Install these two programs first, (google how to ADB tutoria if needed? So after downloading that you will need to download the right drivers (for the voerex) Software name (Driver_WHQL_ML_Ver_4.9.7_All_Win7_LGEAll)(Google Search It)} There's 1 other thing we to have to do before seeing if your decice is listed in ADB. We need to add a line to the Envioronment Varibles section under System Variables at the bottom. Here's how to get there in Win7, right click on my computer, advanced tab, at the bottom Environmental Variblesm, click itlook down under system variables and scrooldowm until you see something called Path and add this line to end of it, ofcourse clickit edit then copy and past his line including the semicolon ;c:\android-sdk-windows\tools;c:\android-sdk-windows\platform-tools now save it amd exit. The reason this is done is so we won't have to contantly navigate through cmd prompt to the directory and list commands. This is prevent you from have to navigate to the folder evertime u want to run the program or any cmds. Now that were all setup lets connect to you phone's data cable to the pc and the phone, and again make sure abd debugging is enabled. Settings, applications, development, the check in the box for debugging, if it's not enabled you will get the turn on usb feature your phone so not what we want. Now opem the cmd prompt run the cmd cd.. then cd.. now you should C:\>, you can run the cmd adb devices now hit enter and you you see a long 14 to 16 digit # then that means your devices is succesfully connected and talking to your PC.That long # should be your MEID HEX# to your phone if you dont see that and you see somethine else then go back though the guide to see if you missed something during setup. If setep properlly in the cmd prompt type adb devices and your phone will automactically show its long#, after that type the cmd adb reboot at which point through cmd promt the device will reboot itself. Here a little secret just because you don't have youtr verison's orignal firmware nor a working ROM on you phone such as froyo 2.2.1 or 2.2.2 doesn't mean anything, you are still rooted and wont have to downgrade to 2.2.1. Side note ( z4root didn't work for my lg vortex, I tried gingerbreak 1.10 and later gingerbreak 1.2 which both worked just fine, z4root just hung on my phone, sry i bounced off topic but i took me 24 hrs of troubleshooting till I got it back up and running.
This method I would say this only applies to the ones that don't have cwm installed on their internal drive it acccidently wiped the original firware off their phones and don't have anything to boot into. I don't have the orignal verizon stock installed, essentially you hit the same buttons on the phone to do a hard reset or to boot into recovery as you normally would. If you neiher on your phone then ADB is your saving grace. Another tutorial I seen was something about installing ubuntu lunux, it just seemed liked to muck work for me, plus I didn't want linux on my box anyways, not til im ready for building a linux kluster later.
let get started...go and download the Adb software which is called Android-debug-brigde...you will also have a visual demo to guide you through the setup) (ADB file) name installer_16-windows,install this this file last to the root of C:/ once done its location will look like this c:\android-sdk-windows ( this is important to make sure you extract the exe to C:/android-sdk-windows (you can take advantage of youtube's a great resourse for viual walkthroughs} or google it,.i have had to do i know's our there , well if you more of a reader search google or xda it will breakdown the core or the installing of the actual files can't post links here but you have to post a minimum if 8 tines b4 you can post links outside this site.
Once all that's setup you need to confirm that its linked properly. Phone off or on during this process I wouldn't think it matters,my devices were on, so conntect you data cable to you usb port and the other end to your phone where you normally power it. This is the time you better hope USB Degugging is enabled. If it is you will see the little Android character and something that looks like a usb icon in the status bar of your phpne, so if you pull down your status bar is will tell your if you are in use debugging mode,. in the status bar depending on where your bricked. if you are in a booploop all its going to do it make that noise of connecting and disconnting. you may have to find fifferent approach to fix it, only solution I can give you if to try home, vol +, and power down til you get a black screen and hope it hangs there there long enough to so you clear it. So it this aproach words on a bootloop let me know in the comments.
Once everything looks good open up your device manager
Just under your computer mame u should see somethig called ADB Interface
under that from the drop arrow you will see android plactform sooner single ADB Interface, click on that and you will see android plattform sooner single ADB Interface, then under modems you will see LGE Android Platform USB Modem, and last at the bottom your youw will see universal serial bus controllers, select that and you should your see LGE Android Platform Composite USB Device, If you see all that that your 100% convered
Now to get your phone out of that nasty brick and we don't need need any firware or Roms to do it...
Open cmd prompt, type cd.. then cd.. again now your in C:\>
now type cd android/sdk/system (note the CD just means change directories) now were in the folder called c:\android-sdk-windows
From this directory is where were going to run our commands since we can't do it in cwm.
type wipe system and hit enter
wipe system you will see a alot of errors like it didnt do anything but that's ok next step
type wipe data hit enter
once done pull cable reboot phone wait to it to come up to where to you have to touch the andoid like your setting up the phone for the first time again, warming u more that lickly will get an FC during setup and it will brick again on the same screen. Repeat wipe system and wipe data again, the gp though the setup on the phone again, if have have another FC one last time so again wipe system then wipe data, this time there shouldn't be anymmore FCs, I have to go through wipe system and data 3 times b4 the FC's stooped and I will able to to to the activaton screen > My phone is a refurb so if would let me past the activation screen this time as when im loading up in CM7. last issue I faced was the accivation screen, Now I did some reading on this and there are a couple of thing you can one of which worked for me., You can tap the four counrers in the clockwise direction which didn't work for me, or what did, I click activcate then entered *228 then hung up, avtivate again *228 hungup, then activate again,*228 hugnup and this time I was able to skip activation anb and was again to load cwm and flash my phone, so its not longer bricked and I dont have to worry about the avivation all though it will comes up U can stip it and It wont keep me from me phone, I have VIOP setup over my 4g LTE, any questions about this type hack just let me know, ( I have an 18 Page Paper about how it works how to set it up, its free and no download charge for the APK) and I will post it. Forwaring the paper 18 pages long and pretty in depth, I dont explain the backend of how it works but just a little, its mainly the frontend and to set it up and all the routing.

Vortex sux
Okay ... so my vortex is nothing more than a paper weight at the moment. When I turn it on, the LG screen comes on for 3 seconds, then the screen goes blank, then it starts over again. I can't turn it off after it starts its boot loop. I have tried using the recovery keys, and nothing. If I plug it into the computer it will turn on and do the loop over and over again, and i still cant power off. I have a 4gb micro with cwm recovery, but i do not know how to get this phone to boot into the cwm recovery. your help would be appreciated.
Here's what worked for me

I was in a similar situation and was able to get to recovery by taking out the battery, holding down the buttons required to get into recovery and then while holding down the buttons, plugging the phone into the wall charger. Once it was in recovery I put the battery back in and flashed back to a known good rom. Not sure why this worked over just turning it on normally, but it's worth a shot.
LG P500

impossible to go back to the V20F V10h
or from 2.3.3 to 2.2.2 with KDZ and I put everything comes to an end, but when I turn on the LG-P500 on the boot and stay in the boot nemoze to convert to the main screen WHY. my English is desperate
make hard-reset:
a) Turn off the phone. If Power Off not working, remove the battery.
b) Press and hold ‘Home’ key and ‘Volume Down’ key.
c) With these 2 keys pressed, press Power button and hold till phone starts to boot in reset mode.

Thank you a lot of combinations of 3 booton Home, Volume Down, Power solve the problem thank you very much
I would really like to return to Froyo, but... I don't understand what rajko34 did.
Like, the v10 baseband is available but where I can get a stock froyo rom to flash with the LGMDP.exe?
If I flash with KDZ, the baseband is flashed/downgraded too?
Thanks in advance

Hi,
I am replying to this post just want that other should aware about the facts that Downgrading from 2.3.3 (V20) to 2.2.2 (V10) is possible and is successful using KDZ. You just have to take care of some below Points before flashing:
I AM NOT RESPONSIBLE FOR ANYTHING GOES WRONG TO YOUR DEVICE. TRY ON YOUR OWN RISK
1. Always Use latest driver from LG and make sure that your device is disconnected and any previous version of drivers should be uninstalled from "add and remove programs" using Windows XP SP3 system (Including LGE Virtual Modem,etc. etc. ..!!! (The one who already have latest drivers and clean PC won't find "Virtual Modem" in the device manager, So just Chill ) ..Check device manager and uninstall if they still there and also uninstall drivers from other vendors like Nokia, samsung, etc.
2. After uninstalling drivers , restart your system and make sure that your user is an administrator and then install New LG drivers from the LG official website (Just Google== LG P500 drivers ). and Disable LGE Virtual Modem if still its appearing in the device manager.
3. Always make sure that USB Debugging is enabled on the device and your system supports USB 2.0 (High Speed), so notification like "Hi-Speed device is plugged into Non Hi-speed USB" should not appear.!!
3. Extract KDZ_FW_UPD_EN.zip and Install msxml.msi and reboot your system again.!
4. Again you need administrator.!
5. Now Plugged the Device via USB.!, System will install drivers for your device. Wait let the system completes the driver installation .!
6. Unplugged the USB from the phone and Restart the Phone.
7. Wait for the phone to Boot and load completely (Approx 5 minutes).
8. Set Display Brightness timeout to 30 minutes and ensure USB debugging is ON.
9. Plug the device again and keep it at a place where it will not get disturbed. (Also ensure that You have Good working Data Cable, Hope Your Original one is still alive )
10. Open KDZ_FW_UPD.exe, select type "3GQCT" and phonemode "DIAG"
11. Click browse and select "V10E_00.kdz" file from where you have download it, I have used Indian version because I have Indian LG O1. (I recommend V10E_00.kdz because i used it twice and it works lika a charm :victory: )
12. Now the Flashing Part .! :fingers-crossed: ...!!. Click Launch Software Update.!
13. The phone will goes to Emergency Mode (Don't panic).! and the flashing process will start.. ! wait for flashing to complete.! Ensure that your system will not goes on Standby or sleep.! And If you are using a Laptop I suggest you to plug in the power first.!
14. I always make my mouse moving while flashing process is in progress. It make me feel better . So you can also try this
15. The flashing process may take 5-10 minutes to complete. and you phone will restart itself indicating the offline battery charging screen.!
16. Wait until KDZ prompt "FINISHED" in the end of the log.
17. Unplug the USB and wait for 5 seconds and press and hold Home+VolumeUp+Power simultaneously for Hard resetting the phone .
18. When The screen Shows LG Logo leave the buttons and Hard reset will take half a minute to complete.
19. Wait and Let the device Boots ups completely. (First Boot will take 5 minutes to get you to the lock screen)
20. Done.!! Congratulations.! You are now Downgraded to 2.2.2 . :highfive:
Good Luck :good:
IF anything went wrong during the flashing process or KDZ gave you any error in between the process.! Please DONT pull the battery out from the Phone. Else It will HARD BRICK YOUR PHONE.! And u are not even able to get the phone Power on..I mean Dead! Just Find Support on XDA and try and try again.! (Also suggest you to do not unplug the data cable, it may also lead to HARD brick the phone.)
In this situation ensure that you have a right flashing KDZ file. and IF you have the right one use different "phonemode" like Emergency, Emergency_CS, etc and try and try again.!
IF still wont work try to shake your phone and touch the screen again and again and try to launch the software upgrade
If still device is not responding try lgmdp method and try to flash a recovery and Image.
If nothing works restart you system and then again launch the software update in emergency mode.! (This option works for me once but i recommend you to try it as a last choice)
Don't pull the battery out and ask for support on xda.! Might be someone save your phone's life.
If the phone is still stucked you have to get it to the service centre. (If your phone is in warranty they will replace the PCB free of cost)
Yesterday I rooted my LG Optimus L9 using LGpwn tool, after that it worked just fine.
This morning I tried to install ClockworkMod Recovery. Using this post. It explains how to download and install CWM Recovery from app that you downloaded in form of APK.
This method did not work 100%, but I was able to reboot normally, so in post it said that sometimes it does not work and you need to download and use Busybox installer Link to busyboxx.
After this I managed to boot in too CWM using app from mentioned thread.
Then problem occurred. After I saw CWM was working I selected reboot device option.
Except now when it started to boot it stops right after Second LG logo (First is static one second one is animated).
I get white screen with "Encrypting" on top and gray line. And one Reset Phone button. IMG they are Dropbox links.
This is followed with Error : Unfortunately, the process com.android.phone has stopped. IMG
I am able to boot in too CWM and I have tried flashing something like Cyanogenmod but I get error Status 7. Tried removing line that checks model, no use.
Tried clearing every cache and fixing permissions, nothing. Formatted everything still no use.
Dear XDA community That you in advance.
I fixed my phone by going into SW upgrade mode, and using the Upgrade Recovery function of the LG Software Update tool or whatever. Be sure you don't have any http servers open
Sent from my LG-P769 using XDA Premium 4 mobile app
I got the same problem, but when I try to access to SW mode and connect to LG Software Update tool to restore my phone, the phone keep disconnect and the phone screen will turn off, so I fail to restore my phone, I have already re-install the USB driver and changed a several USB cable but the problem still, but I tried to restore my phone with SW upgrade method since last night and is was OK, can anyone help me?
---------------------------------------------------------------------------
The Problem Solve Finally, the solution is I plug the battery back to the phone after access to LGMobile Support Tool, and after finish the restore process, the phone will restart but keep boot loop, then I perform the hard reset (Remove the Battery and insert it after few seconds. And now do the 3 button HARD RESET. First press VOLUMEDOWN and HOMEbutton. Then Press Power button only for 3 seconds and release power button but dont release VolDown and Home button and KEEP BOTH PRESSING until you see a Bigger Green Standing Android and circulating Molecular structure above it. DONE! ), then the phone begin work~~~

Then it will all work, I can't even install a custom rom My bootloader is unlocked, rooted phone, installed recovery, see my thread about the error I get!! please!
help lg p768 encrypting error problem
can someone help me please.
i have the same problem from the starter of this thread..
installed recovery apk and goes to encrypting error.
i dont know what to do and how to begin to solve my phone problem.
thanks
I think this should work for people who cannot get into recovery mode, computer cannot detect the phone or have security error message.
How I bricked my LG-E450b
I thought rooting for this phone was like my Samsung phone, so I installed Kingo-oneClick-root, got root and deleted all of the bloatware.
Little did I know that I could actually brick my phone by deleting some LG apps (Stupid LG).
Symptoms of my bricked phone
Secruity error message
Phone would not be able to go into recovery mode (Volume down + Camera button + Power button). It would restart after 3 seconds or so after the android loading gif.
Phone would not be detected by the computer
LG support tool could not detect phone (since computer cannot detect phone)
LG support tool would stop at 4% when trying "upgrade recovery"
I was basically stuck and thought my phone was hard bricked. So I started playing with the phone hoping for some magic thing to happen and I got lucky!
How I fixed my issues
Remove case and connect the phone into the computer with standard usb cable
Power into recovery mode (Volume down + Camera button + Power button)
Just before the phone displays the security error, remove the battery (phone still connected to computer).
Put battery back in and turn on the phone normally (no recovery mode)
If it worked then there should be a white message on the bottom left of the phone saying "Download mode: "
Optional: If the computer shows that the device attached has an error then you are in the right direction! Go into device manager (run devmgmt.msc) and right-click on the device that is not detected and uninstall
Optional: Hold power button until the device shuts down and repeat from step 2, the next time you get into download mode the computer will detect your device
Open the LG Support Tool (almost done) (attached in this other forum post)
The phone should get detected by by the LG support tool. Try to update the firmware. If the Support tool says that you already have the latest firmware then go in Options->Upgrade Recovery and put the model number or IMEI/ESN/MEID of the phone and click ok; the recovery process will start and your phone should work
Note: If the phone is not detected by the LG Support tool, then it will not work (it will stop at 4% when doing the upgrade recovery). The phone has to be detected for this to work.
Conclusion
These are things that worked for me, but I am no expert. This is not a full proof guide and I am only posting the steps that made the phone work. It might possibly be that you don't have to do all the steps described above to get into download mode, i.e you would just have to remove the battery at the right time to activate the download mode.
I am posting this describing the exact steps I took, so this can hopefully work for someone else.
Good luck!
TL,DR : Remove battery just before the security error message and reboot phone to get into download mode.
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.

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).

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!

Did you use HOME CSC or the non HOME CSC when flashing?

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).

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.
