[Q] [H850] Cannot boot into fastboot (no command) - LG G5 Questions & Answers

After flashing my phone back to stock using TWRP and LG-H85030a-Flashable.COMPLETE.zip, I tried to install magisk. Unfortunately TWRP crashed at that moment.
Since then every time I do ADB reboot recovery from my phone, I get the No command screen with the android on its back.
I tried to following things to solve this:
- Press the volume up (15 sec) + power in recovery
- Press the power 3 sec + volume up in recovery
- Reflash the phone using LGUP and multiple KDZ using upgrade with multiple versions (6.0 - 7.0 -8.0)
- hard resetting phone (clear all user data)
Unfortunately LGUP does not let me choose the refurbish option. I checked my phones IMEI and I'm supposed to have ITA region, but even with the the ITA 6.0 rom H85010i_00_OPEN_EU_OP_0923.kdz I cannot choose refurbish.
I tried LGUP 1.11 with the dlls and LGUP1.14 with UPPERCUT.
I would really like to root this phone but without fast boot this seems now impossible. Does anybody have any suggestion on how to resolve this issue?

Hey guys,
Not sure how I can delete this message, I found a way around my problem.
Turn off device.
Press volume down, put USB cable into power plug.
And it booted in fastboot. From there I could install TWRP.

[Q] Bootloader Encrypting Error | L9 P760

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

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~~~

[SOLVED] Need to flash System partition through fastboot

Hello.
I recently sold this phone and went to factory reset. no problem. However, i forget i deleted the STOCK home app. THere is no launcher on the device so LG Setup Wizard simply crashes when finished setting it up. There is NO ADB since the setting has been erased. I need to re-enable it in settings but can't get that far since LG Setup Wizard keeps crashing..
I think i'm screwed.. what a stupid way to brick..
Device is: LG Optimus L9 P769 T-Mobile variant. Thanks guys!
you should be able to put your device on download/emergency mode and flash a kdz file with lg tool, you tried it?
if don't try yet, take out your battery, hold + volumen botton and put your battery again holding even + volumen key, and conect your to your computer, it must show the yellow screen with the legend download/emergency mode, and in your computer must be install the drivers, to exit the download/emergency mode just take out the battery or hold the power button, and for flash a kdz file, search a tuto, there are many, and many videos to make it easy . All this process let your device as new, all applications and configurations
I am aware of that mode but when attempting to flash that way before, after upgrading to jellybean, it would never flash for me. So I didn't even try it. I'll give it a shot though. I also was able to download one of the cwm backup zips posted in the other thread and extracted the system partition then created a .img image out of it and will try both your method and flashing that img file when I get home from work. Thank you for your post!

SOLUTION
Installed the ICS uboot.
Booted to SW Upgrade mode via plug USB, hold volume up button, place battery into device
Launched KDZ update tool and it connected and went smoothly!
If you have the JellyBean uboot, it won't connect in SW Upgrade mode if booted manually.

Bootloop and no way to enter in recovery or download mode

Hi guys! Yesterday I decided to unlock the bootloader, flash recovery (twrp 2.8.6) and the cyanogen 11 nightly. Everything went good until I tried to install the gapps, I noticed that the physical shortcut to enter in recovery (after the turning off, of course) didn't worked: the phone restarted or boot up the rom, but I was able to enter in recovery from the advanced restart menu from the rom. Going into the info of the phone where it says kernel there was written "unknown" and no way to overclock. So I decided to reinstall the kernel (the cyanogen11extended) from twrp, everything went good except that I couldn't restart into recovery, it stuck on rebooting until shutdown. So I tought let's use fastboot to erase ad flash the recovery partition and the kernel, but it didn't do anything even if on the cmd said okey and finished in something about a second, but when i tried to enter in recovery I always get stucked on rebooting. So I tought"well if I have the system image I could flash it with fastboot and restore the stock kernel", so I erased the system partition and tried to flash the system.img and I get the message that it is too big for the destination device. Now I don't have a system installed tye hotkeys don't work and I'm stuck on LG screen logo.
There is a solution or do you suggest to send the device in warranty, instead?
Pull the battery and try to enter download mode.
Hi vagelis! You mean without the battery? The hotkey is vol up+power, right?
Edit: i tried without the battery pressing the vol up + power (also tried with vol down + power) and it doesn't work, on the screen I have an image which says to put the battery in, and holding the keys has as only result to reboot the phone showing the image... I guess there's no hope right?
Edit2: I entered download mode using the g2 method, now I have to downoad the kdz rom and the lg flash tool to unbrick, right? But where I can download it since the lg site for the firmware is apparently down?

Ok guys, I was able to unbrick entering in emergency mode e doing the flash tool stuff. The strange thing is that when I start the flash tool putting the file kdz and going forward in the next window, when I click on read phone info the program stops working, if I click directly on stuff then the lg mobile support tool is opened. Now when it starts to write on the phone, the tool says that an error occurred (something like "the server is offline) but on the phone it says the port com and start to download the rom. If I say ok to the error of the lg mobile support tool it stops the firmware update and stops the program, if I don't click ok the firmware update end is work unbricking the phone.
Now I noticed that with the stock rom from the version v10h until the last one towelroot is not working, so I downloaded the v10g germany version (since the italy version was offline) and flashed with the same procedure as I have done with the unbrick, so I could run towelroot and flash the twrp and the cyanogenmod11. Thank you so much for your time!!
The topic is quite old, but I've just solved that problem. You should just do it:
1) hold power and vol down till you see LG logo -- immediately release these buttons and 
2) immediately hold power and vol up button to enter into factory reset menu. 
Then click "yes" and next "yes", too.
That's all.

honor 5X update freeze/loop - no TWRP recovery possible

Hello everybody,
since saturday I have a really big problem. Until now I tried to find a similar problem from an other person in the internet in order to fix mine but that was not possible.
So in my last hope I am now writing it down here. Hopefully someone can help me:
The phone was/is rooted and has TWRP as recovery installed (v3.21). The software is still the original EMUI.
On saturday my Huawei Honor 5x (Model KIW-L21) gave me the notification that there is an software update avaible. So I backuped everything with TWRP to my sd-card and copied it to the computer. After this I ran th eupdate. The update downloaded the new software, then rebootet to the recovery, installed the update.zip automaticly and rebootet again. Then there was written on the screen "Huawei software installing ... DO NOT unplug usb or press any key!". Also there was "0%" all the time. It did nothing. also the phone was not connected with usb.
After an hour I long pressed the power button. after two seconds there was the text "Warning: The powerkey is long pressed, please release powerkey to avoid system crash" displayed. I pressed it longer and the phone turned off.
Now I have the following problem. When the phone is turned off, I can:
press the power button: the phone starts, the "honor ... android" logo is shown but nothing more happens. ("fastboot devices" -> no devices found, "adb devices" -> device found but no permission to enter commands)
press the power button and the volume up button and the volume down button at the same time: normally this should take me in the recovery mode, mut it doesn't anymore. Instead the "EMUI" update screen is shown (see above "huawei software installing ..." with "0%") ("fastboot devices" -> no devices found, "adb devices" -> no devices found)
press the power button and the volume up button at the same time: I get a huawei menu with three buttons: "reboot", "wipe user cache" and "factory reset". I tried both (wipe and reset) wich both finished without an error. But nothing changes ("fastboot devices" -> no devices found, "adb devices" -> no devices found)
press the power button and the volume down button at the same time: I get an "eRecovery" menu from huawei with three buttons: "Reboot", "power off" and "Recover with latest software". The last button lets me connect to my wifi and then "searching for packages", with failes all the time. ("fastboot devices" -> no devices found, "adb devices" -> no devices found)
This problem occures with and also without the sd-card. Also there is no "update.zip" or "update.app" on the sd-card.
I really hope somebody can help me. I only need to get into the recovery. If I am there I can recover the backup or install a new ROM. That would be no problem for me. But at the moment I get nothing :crying:
Or maybe a tool to reset the phone completly? to start over from the beginning?
greetings,
Christopher
PS.: Thanks for your efford.
PSS.: Sorry for my bad english, I really try my best and hope that you understand what I am trying to say.
Same problem here... Please help us :'(

to enter fastboot mode
1. Place the device in fastboot mode:
Turn off the device. (then wait for at least 2 seconds) For a mobile phone, press and hold the volume down and power keys simultaneously for at least 10 seconds (for a tablet, press and hold the volume up and power keys).
2. If the above operations do not switch the device to fastboot mode, please try the following steps:
Turn off the device. (then wait for at least 2 seconds) Then insert the USB cable and press and hold the volume down and power keys simultaneously for at least 10 seconds.
Step 2 worked for me every time

AGAIN AND AGAIN, when you receive an update notification you MUST first flash back to stock recovery or it won't update with TWRP !!!
- To recover a stock recovery you need to boot onto download mode/your bootloader mode (Power+Volume Down) : plug your phone to your computer and type "fastboot flash recovery recovery.img".
From there you will loose your connexion with your computer. So unplug your phone and reboot manually holding down the Power button for some seconds.
If the system ever update your phone, BE VERY PATIENT !
The above note should probably part of a sticky !!!
If you don't get back to your Home screen and if you need TWRP back, reboot again onto download mode/your bootloader mode (Power+Volume Down) : plug your phone to your computer and type "fastboot flash recovery twrp.img" (or whatever the custom recovery name).

The problem a lot of people were having is TWRP flashed enough of the update that they lost custom recovery and had no way to get to the bootloader / fastboot ... that's why I posted the instructions above and in about 4 other threads.
Did you ever get your phone updated ?

"fastboot & rescue mode" with a working usb connection.
What is the next step? If I now flash the stock recovery, does the phone manages to finish the system update?
Or should I flash the twrp recovery and not the stock revocery?
greetings,
Christopher
EDIT:
I flashed the stock recovery and also the twrp recovery. both times i startet the phone and hoped the installation of the new software will go on. But it didn't.
So my problem is still resistant. so what can I do? How do I stop the update from blocking my recovery? I do not need the update. maybe I can reset my device with the fastboot access somehow?

All the full updates are in the file depot
Use stock recovery plus the full update for your version.
You have to hold volup + voldown + power to start the update
Refresh TWRP / Root and your good to go

I found the stock recovery at https://www.androidfilehost.com/?w=files&flid=51004 but I have no idea what update I must use and how to use it.
Could you please give me a concrete link with a little introduction? Do I have to copy the update file to my sd-card? or do I have to use the "fastboot update *" command?
(Most of the files are for "KIW-L24" but I have a "KIW-L21" ... is there a significant difference? Od do I can use also the other files?)
Also, don't I have to stop the wrong update first?

both did not work. I copied them into the "dload" folder in the root of the sd-card and started the phone with volup+coldown+power.
The only thing the phone said was "Software install failed! ... Press powerkey to conrifm ... Shutdown system now".

The only way I know to flash a ROM, is to go over TWRP.
So I now did the following:
Phone power off
connect to pc
voldown+power
in the fastboot flash the recovery from twrp
shutdown
copy the "customromtemplate-5x-plk21-b130-r3.zip" to the sd-card
volup+coldown+power what normally starts twrp, but only the huawei update manager is shown
I only need twrp, no update and nothing else.
What options do I have left, because "flash a ROM" is not working ...
How can I stop this terrible update that is blocking my twrp?

I flashed TWRP using "kiwi_twrp_3-21_recovery.img". I also used this one last time (one month ago) and it worked then and also now.
Flashing was successful, but when I press volup+power I get a huawei menu.
At the top there is the "EMUI" circle and below there are three buttons:
Reboot system now
Wipe data/factory reset
Wipe cache partition
I can move around in this little menu by using the volume keys.
But this is not TWRP.
And normally I enter the recovery by using volup+voldown+power. But this is currently blocked by the update progress from huawei.

http://forum.android.com.pl/topic/205126-instalacjaodzyskiwanie-systemu-rom-za-pomoca-fastboot/
This is the polish version of manual, I will write you how to do it:
1. Download ADB and Fastboot
2. Extract to c:/adb
3. Download from this thread firmware for you (extracted version!) http://forum.xda-developers.com/honor-5x/development/stock-kiw-l24-l21-t3312684 If you have problem what firmware you have to install, take look at the back side of phone, at the down you will se KIW-L21 or 24 (or another). Copy all files to adb folder
4. Rund adb program
5. Write in the command line: cd c:/adb
6. Connect phone to usb to download mode (power and vol- combination)
7. Write in fastboot command: fastboot flash recovery recover.img (or recovrey .img, see the file and type it name) - wait for install
8. And now: If the flash is succesfull, reboot the phone to recovery (power and volume+) and wipe all data. Phone have to work.
But if flash is not succesfull, plug again usb with download mode
9. Write this commands: fastboot flash cust cust.img -wait for install
and: fastboot flash system system.img -also wait, system.img can took a while
10. Now you will enter recovery and wipe all data
11. Again plug usb cable and install firmware with those commands:
fastboot flash boot boot.img
fastboot flash cust cust.img
fastboot flash cache cache.img
fastboot flash userdata userdata.img
fastboot flash system system.img

With this I am not able to start my phone again. It will boot normally and I have a clean android. No userdata and no root.
So I now did the same like last month:
Unlock OEM -> not necessary, because it is already unlocked
install twrp with fastboot
reboot to twrp and there it is again
I did exactly what you said and also I did exactly the same thing I did last month but both times there is the same result: TWRP will not show up.
The "stock recovery" is blocking twrp in some sort of way. I can do whatever I whant ... volup+power out of the fastbook mode, or with "adb reboot recovery", or other ways ... twrp will not show up.
How is this possible? I also tried different twrp images. (The "kiwi_twrp_2-27_recovery.img" and "kiwi_twrp_3-21_recovery.img" out of your repository, and also the "twrp-3.0.0-0-kiwi.img" and "twrp-3.0.2-0-kiwi.img" from the twrp website itself ... always the same result: no twrp)
I am really at the end of my knollage

First off thanks for the very informative post.
Without actually having the phone in my hands I'm also stumped at what to try next.
After flashing TWRP and still in the boot loader unplug the USB before you reboot with power and volume up.
That's all I can think of right now

I must thank you for all your help
So I now read some more articles and tried some things. So there are old problems solved, but also new problems came up:
For me it is no longer possible to flash a recovery that is permanent. I have no idea why but I am ignoring it, because I can start the phone with voldown+power into bootloader and then use a usb-connection to enter the following command:
fastboot boot twrp-3.0.2-0-kiwi.img
Click to expand...
Click to collapse
So i can enter twrp temporary and because I do not need TWRP this often, that is ok for me.
BUT:
with the extracted "UPDATE.APP" and flashing some "*.img" files manually (see my last post), I have a more or less working "L21C432B130" version of android.
So now there is everything original (recovery, system, ...).
The update to "L21C432B140" is still not working. But that is also something I can live with.
So now I whant to restore my old system in order to have my old data/apps/... .
So I enter my temporary TWRP, go to Restore and select my old backup. Then the restore starts. Restoring EFS, Restoring efs2, Restoring Recovery, Wiping System and Formatting System using make_ext4fs. All of this in this order are successful. But the last operation "Restoring Data" failes with the following error message:
extractTarFork() process ended with error 255
Click to expand...
Click to collapse
So I searched on xda and found out, that this could be ANYTHING. I tried five or six different methods in order to fix it. In the end I am not sure what really fixxed it, but now I can restore my old update without any error. The phone now runs and I have all my old data.
There are four main differences on my phone to the time before I tried that damn update:
1. I have less internal storage
2. I have no TWRP permanently avaible
3. I can not Factory-Reset
4. I can not use a "UPDATE.APP" inside a "dload" folder on the sdcard
(the last two things always failes)
But as long as the android system now runs smooth again I can live with these things.
Is there maybe anything else I should be careful? maybe a known bug/problem that I have not seen yet?
The reason why I wanted to update in the first place was, that I have problems with my sd-card.
Some Apps do not allow to use the external storage. Easy Voice Recorder is the main problem. But also the Call Recorder has problems with it.
Is this a well known bug? Does a update helps? And if so, how do I update? (Now I know how to rescue my phone, so I could try it again xD )
Or does this problem gets solved with an custom ROM? If so, what good custom ROMs are out there for the honor 5x?
Or is this a problem that is not possible to fix on the honor 5x? Because these apps does not have this problem on my HTC One M9 ...
And thanks again so much for all your help

from your current state you can try flash recovery with TWRP by choosing install / image / your version of TWRP / choose recovery / swipe to flash
Now choose reboot / recovery
As for the sdcard try the sdcard fix for kit Kat in the play store. It works for some older apps.

But I did try with KIW-L24 B151 with the result I already mentioned previously : almost bricked... ^^
But I always managed to get into Bootloader/Fastboot to flash back any kind of recovery...

All the full updates are in the file depot
Use stock recovery plus the full update for your version.
You have to hold volup + voldown + power to start the update
Refresh TWRP / Root and your good to go

So i have this issue too. im so stupid for doing this. I can go into fastboot mode and i flashed stock recovery and when i rebooted into recovery it still said that it was updating the firmware. I flashed twrp after that and it had the same message. am i doing something wrong or is it my phone? I tried rebooting into bootloader using adb but only fastboot will reconize my phone so adb also wont work. could you guys maybe help me?
Edit: Yessss. i got it using the temporary command. Thank you guys all for your help. it was so stupid of me to flash it with twrp still on it. Thank you all very much

Tab S6 stuck in bootloop, can't get to recovery 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.

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).

Why flashing only the bootloader first? At the moment I'm trying to recover my s20 fe from a bootloop without losing my data

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).

Any tips in recovering my stock s20 fe from a bootloop without losing data? already tried Odin but without success the first try

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.
