first time installing custom rom - Galaxy S III Q&A, Help & Troubleshooting

Hello everybody!
so a while ago i got a sgs3 i9300 with the official rom 4.1 now i wanted to flash marshmallow (CM13).
WHAT I'VE TRIED
- rooting using kingroot (no success on 50% my samsung turned itself off)
- using odin to flash a new ROM: cm-13.0-20160722-NIGHTLY-i9300.zip with the recovery: TWRP - 3.0.2-1-i9300.img.tar
nothing did work
fired odin up with admin rights then i got in download mode using (Vol. down + home button + power button) plugged my usb cable into the phone pressed Vol. up plugged usb into laptop and in odin it should say added or something but that didn't happen so moving on i selected the twrp and then i got this message: all threads completed. (succeed 0 / failed 0). What did i do wrong???
what i used a walkthrough because i really suck at things like this. walkthrough: youtube.com/watch?v=xRHRP5TfOvc
or can you guys point me into a different direction?
thank you already for looking into this.
Good night,
Chaos

Not that im best suited for this, but ill try to help you
NOTE THIS IS ONLY FOR I9300.
ROOT
Step1- Enable USB Debugging, Settings -> Developer Options and enable it.
Step2- Install samsung drivers on pc, so that phone shows up in odin.
Step3- Download CF AUTO ROOT by chainfire
Step4- Put your phone in downlaod Mode.
Step5- Turn on odin and plug your phone (This is what it will look like if your pc recognized phone)
Step6- In odin select CF AUTO ROOT(It shoud look like this, and note i was to lazy to plug my phone so it's not showing up in odin xd)
Step7- Press start in odin, your phone will reset and you are rooted.
RECOVERY
Installing recovery is pretty much same, select in odin recovery and flash it.
ROM
-Download ROM and GAPPS put both files on your phone, put phone in recovery.
- Wipe Dalvik, Cache, Data and System.
-Now go to install and find rom that you downloaded click on it and install, then install gapps.
-Wait for phone to boot up.
And be careful i am maybe wrong in some stuff in guide sooo dont blame me if you brick your phone
And sorry for bad English.

ok i've done what u said it worked! but now i've hit a another wall, now when my phone has booted up and i selected my country when i try to press next a little lock appears left of next and something scrolls down.
any ideas?

[Q] Samsung S2 ICS rom suddenly stuck on load screen.

Please please please could anyone help!
About a month ago I upgraded to Ice cream sandwich (LP7) and then rooted my S2. All worked fine for 3 or 4 days and then suddenly it crashed for no reason. I suspect, but am not sure, that it did an automatic update. On rebooting it just stops at the Samsung S2 screen with a yellow triangle.
For the last few weeks i have been trying to find a fix, but am at my wits end now.
I have gone through the different solutions on your site but to no avail also where mine seems to be different is that I can get into boot mode and odin always says its successful. I have tried different pc and usb cable too just in case that was an issue
I can not get into Volume up mode, but i can get into boot mode with volume down. I have tried re loading a few different rom's and Odin says that the transfer was successful each time, however it is still stuck at the same place on reboot.
Tried reloading kernel and re partitioning, and again Odin said it went OK, but still stuck on start screen.
Tried using a jig and turned phone on, but it the phone just went to the start screen again.
If i could just get into reset mode, i could clear the memory, but this is not working either.
If anyone could help i would be very so grateful.
Thanks

You need to flash a ROM that will wipe your data at once.
Is your phone GT I9100 or GT I9100G?

That is a special .tar edition. You simply flash it just like a single file firmware (as PDA).
Good luck

You need to special .pit file. I'll post you the link (for the .pit file and instructions) very soon

Try this I did and it worked to get mine booting after a bad update.
I messed around with it using several methods of getting it to boot into download mode until I finally got it to do it. I think I left it plugged into the USB, powered it down until I saw the charging screen, then I proceeded to play with the different ways to hold the buttons to get it to download mode. If you are persistent enough and read a little on booting methods to get bricked phone into download mode you will succed if not then your not for the world of trial and error... the main thing is do the first steps I said before until it works
1. Get into Download Mode (WITH THE PHONE PLUGGED IN) by following the steps below
*Turn off the phone until you get to the charging battery screen (keep in mind, your phone is currently PLUGGED IN)
*Press volume up and down, and power all at once.
*As soon as the screen turns black, release your power button.
2. Unplug phone from USB
or try
2. Remove everything from your phone (SD card, sim, battery).
3. Plug your phone into your computer WITHOUT the battery, as you have already taken it out in the last step.
4. Press and HOLD vol. up and vol. down.
5. As you are HOLDING these buttons, reattach your battery.
6. You should be in Download Mode.
7. Unplug phone from USB
any how try try try until it works
Once in download mode
Get your files together for your phone, and use Odin 1.85.
Plug into Odin and make sure it shows yellow and its added!
1. Now if your files have like 3 files and the exact .pit file for your phone if available.
I found mine here (Find yous stock firmware for your phone)
CLICK HERE
2. Click the PIT button and browse to your exact .pit file for your phone *It should now have added a check in the re-partition box under the options area of the Odin window. If not CHECK IT!
***If you don't have your .pit don't worry about this unless you suspect, or have a bad partition
3. If you have just 1 file just click the PDA button and load the file. If you have 3 then you will load the PDA file in PDA, the Modem file into PHONE, and the CSC file into CSC, there are way too many phones to link all the files so get you stuff together!
4. Now hit start.
5. When done and the phone shows the first sign of starting up IE Logo or whatever... immediately unplug the battery from the phone to shut it down.
6. Now put it back in and start it in Upload mode by pressing Vol Up, Home at the same time then the Power button.
7. As soon as the phone shows the first sign of starting up IE Logo or whatever let go of all buttons and using the Vol Up down Choose the Clear Cache option and go through and make sure you factory reset it if you can just for good measure.
8. Reboot
9. Now when the phone shows the first sign of starting up IE Logo or whatever take out battery again to power off
10. Now put it back in and start it in Download mode by pressing Vol Down, Home at the same time then the Power button.
11. Once in download mode Hook up to Odin again and flash it with a root kernel for your phone. Do not ask me just find it. I did it took time but I got all the files together over several days of reading and collecting the correct ones.
12. When done and the phone shows the first sign of starting up IE Logo or whatever... immediately unplug the battery from the phone to shut it down.
13. Now put it back in and start it in Upload mode by pressing Vol Up, Home at the same time then the Power button.
14. In most roots you will now have a advanced or mounting options and more options to use.
15. I cleared the Cache again, Cleared the Davilik Cache, Went into a option and actually mounted the cache formatted the Cache.
16. Use the option now to restart the phone...
And mine started up installed the apps and I am up and running, nice and smooth and no issues so far
I hope this helps out someone whos just about to go off the deep end, as I was there and patience and trial and error came up with this step by step way to recover mine. Thank me by hitting the little thumbs up THANKS button below this post.
And if your so happy your phone is up show your appreciation by buying me a Pepsi

[Q] Galaxy S II GT-9100 shows: Firmware upgrade encountered an issue after unrooting.

Hello everybody,
About 2 months ago I rooted my Galaxy S II and flashed the Resurrection Remix Jelly Bean ROM v3.0.6 for Galaxy S2 i9100 with a Siyah kernel. (As I am new to this forum I can't post links, but I got it from Galaxys2root . com
But yesterday I encountered an issue and my phone was shutting down constantly, so I decided to unroot it/flash back to stock ICS firmware.
I used galaxys2root . com(galaxy s2 unroot) too to try unrooting it .
I used Odin3 v1.85 to flash the stock firmware but it just stopped at about 75% (stupid as I am I forgot to write down the error.)
CWM was installed with the root but I don't have it anymore so I can't use recovery to use a backup (which I had made) and when I got in download mode in the top left it says Product Name:GT-9100
Custom Binary Download: Yes (2 counts)
Current Binary: SAMSUNG OFFICIAL
Also my PC doesn't recognize my phone in Odin, even when reinstalling Samsung Kies.
When I boot my phone it now says: "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again."
But as Kies doesn't work, it won't even start on my PC, I don't know how to fix my phone,
The main problem is that Odin does not recognize the phone even when reinstalling drivers and Kies, with Odin working I could flash the CF-Root or would that be dumb to do?
Now the question: How can I get my phone back to work?
Thanks.
click on volume up + home key + power to boot into recovery and then do a factory reset, after reset cleck go back, then reboot phone.
If it is a software issue, your phone should work.

Well, I tried that but the message keeps showing up, I can only reach download mode. It looks like the root is gone?
Also, do you mean recovery like CWM Recovery or is there a standard recovery on the S II?
there is a standard recovery on the phone which is replaced when rooted to a newer version.
If something has happen to the root, it should default back to recovery 3e that comes with the phone.
okay I am going to try the following: Removing battery, put it back in, Volume up+Home button+Power button and I'll see what happens.

Still getting the same error message..
Would it work if I use a .PIT file and check re-partition in Odin? (if i get Odin to recognize the phone, maybe on another pc)
You might want to try all pc's usb ports, the usb cable and also download an older/newer Odin version.
If non of the above works, it's time for you to try another PC.
PS: you did read this, right?
ok just got back from school, I would try it now if my telephone would work.
problems seem to have got worse, I charged it the whole night, atleast, I thought i did. I just put it in download mode when it gives me the message:
"Load Battery!! Can't download!!" do you know how I can make this work?
So at this point my main problem ,besides the battery, is that I can't get Odin to detect my phone but I will try it on another computer.
take bat off and reinsert it.
I don't know what to put here...any ideas?
well, I don't know if it matters but my phone doesn't display the charging screen. Is that a problem?
hum....yeah.
I don't know what to put here...any ideas?
and it doesn't say "load battery" it says "low battery" But that is almost the same
I don't think so....never heard that expression before.
I don't know what to put here...any ideas?
---------- Post added at 02:40 PM ---------- Previous post was at 02:39 PM ----------
charge your bat in another device, or manually.
I don't know what to put here...any ideas?
I will charge it first, and use another phone, and then try the guide you linked to and then report to you.
tried it on another pc and it still doesn't work, Odin3-v1.85 does not detect my phone. If it would I could get it back to work but without Odin the only option I can think of is sending it back to Samsung, without warranty, and paying it myself. Or are there more ways to get Odin to detect it, or are there other tools like odin?
Do all Checklist:
Reinstall PC drivers
Charge your phone, just plug it in a charger atleast 5 hours.
Boot to recovery.
Flash using this guide
http://androidforums.com/galaxy-s2-...t/482994-rooting-galaxy-s2-dummies-guide.html
and go to Jelly bean!!! leave ICS...
That Tut worked for me...
Check Odin version aswell is that the latest?
ok I will try that, I'm going to charge it now. Btw how do you reinstall PC-drivers? Reinstalling Kies or the Samsung Drivers?

Should I do this while it is in download mode?
I will try to explain what happened: I was flashing the stock ICS firmware, it was doing the FACTORYFS (don't know if it is a file) when it suddenly failed, but Odin still detected my phone. I retried it and that probably made it worse because after that Odin didn't detect my phone anymore. And that is the main problem

Unable to use phones recovery mode

Hi
Sorry my first post is a cry for help.
So I'm trying to install CyanogenMod Android for Samsung Galaxy S II ("i9100") using the following guide http://wiki.cyanogenmod.org/w/Install_CM_for_i9100. But each time I put the phone into recovery mode I get the following:
Odin Mode
Product Name: GT-i9100
Custom Binary Download: Yes (2 counts)
Currently Binary: Samsung Official
So I'm unable to install ClockworkMod
My Kernel Version is 3.0.31 - 1069234 [email protected] #3 SMP PREEMPT Tue Mar 19 19:18:54 KST 2013
I've previously rooted by using this guide http://forum.xda-developers.com/showthread.php?t=1125282 and its worked fine I was even able to install another ROM something a little closer to the Stock.
Odin is able to see my phone when its in normal mode but unable to see it in recovery mode.
So currently I'm extremely stuck and have exhausted all my googling skills.
To get to recovery its holed vol up home button and then power holed all three till it boots to recovery. Download mode it vol down home and power. Odin doesn't see recovery

Andrew is correct, you're in download when you think you're in recovery. It says Odin mode... That's download.
As already stated, use the volume up key, not down to get recovery mode.

I can see him starting a new thread soon. Its gonna be either "help iv bricked my phone" or "help I cant make calls" op you really need to read more. Lots and lots of reading.

Hi
Thank you for the replies already, I can get my phone into recovery mode but Odin and heimdall are unable to see the phone (tried this on multiple computers). I can also get my phone into download mode (Vol up + home + power) but each time I try to install the ROM it fails, but this is not using Clockwork to install. I've tried to get it into fastboot (vol up + vol down + power) but the phone just boots up, I was hoping I could revert my recovery mode.
So currently the phone is stuck with this ROM unable to flash Clockwork and unable to install CM.
Any ideas?
Thank you
Edit: It appears in my haze of typing this last night I got mixed up between recovery and download. So Odin and heimdall are unable to see the phone in download mode (I press vol down + home + power)
Look at @Hopper8 topics and read trouble shooting with odin. Btw what firmware/rom are you on. So you dont have stock or custom recovery? What method did you use to root?

Hi
I'm on Jelly Bean 4.1.2 and the Rom is http://forum.xda-developers.com/showthread.php?t=1544487 Samsung Galaxy S II GT-I9100 Stock Official Firmwares. Build Number: JZ054K.I9100XWLSN.
I will try @Hopper8 guide:
If Odin won't recognise the phone ...if it does, continue to 'Preliminary Steps'
Firstly, keep trying. Many users will find that Odin will recognise the phone in download mode eventually, but this will take perseverance. Note that if you do get Odin to recognise your phone in download mode, attempt to flash a stock ROM then. Don't unplug it thinking 'you'll try again later'.
Things to try if the phone isn't recognised by Odin:
Open Odin without the phone plugged in. Enter Download mode without the phone plugged in. Now, plug the phone in and wait a few seconds.
Didn't work? Try again in a different USB port. Still didn't work? Try all the USB ports, and then a different computer. If that doesn't work:
Uninstall the USB drivers using Revo Uninstaller. This program can remove the registry edits from the drivers, giving you a completely clean install of the drivers. Reinstall the USB drivers: Samsung USB drivers. If you are using Windows 8, I strongly recommend you try Windows 7/XP. These drivers don’t usually work with Windows 8. (See here if you’re on Windows 8.) Otherwise, use the linked file to the Samsung USB drivers.
If you're still not having any luck, then follow these steps: (Credits to 4-2ndtwin)
1. Turn off both the computer and phone. Fully shut down.
2. Disconnect phone from computer: the USB cable from both the computer and phone.
3. Boot up the computer. Log in and let it settle.
4. Start up Odin and let it settle.
5. Put phone in download mode.
6. Connect phone to a USB port.
If that doesn't work, keep repeating those steps, with different USB ports on your PC/laptop. Change the USB cable you're using, multiple times (preferably use the cable that came with the phone). If all that doesn't work, start again at 'If Odin won't recognise the phone' on a different computer. Keep persevering

And get back to you. Thank you for the information.
Make sure usb debugging in on in phone settings. When you have it working with odin flash philz tar not zip kernel as that will give you root and custom cwm recovery.

Well I feel a little silly right now,
I did original find @Hopper8 guide and tried different USB's till 1am but nothing worked. Just tried again and hey presto it work and CyanogenMod is now installed along with Clockwork.
Once again thank you for the info and for taking pity on this noob, I will endeavor to learn more and try to help out on the forums when I can.
Thank you
Them late nights can make you miss the simple things. No pity mate. Just happy you're sorted.

Sorry for being late to the party. OP, glad you got it sorted and I hope my guide was of some use
Great work as always andrew :good:

Tutorial - Root for US Cellular Galaxy Mega

So I have some great news for all you US Cellular owners out there. I have found a way to root the Mega. To my knowledge this is THE FIRST ROOT FOR THE US CELLULAR MEGA. This will only work for the 4.4.2 version so make sure you have updated or flashed it in odin.
I hope this tutorial isn't too confusing. Sorry I'm not a good teach but I want to get this out to the people who are having trouble getting rooted.
Things you will need:
1. SCH-R960 Device (US Cellular Galaxy Mega)
2. A good micro usb cable. Preferable the cable that came in the box.
3. A PC
4. Odin 3.09 http://odindownload.com/
5. CWM Recovery http://fs1.d-h.st/download/00066/7VS/i9200-cwm-recovery(201362118259).tar
6.And the actual root file http://download.chainfire.eu/446/SuperSU/UPDATE-SuperSU-v1.99r3.zip?retrieve_file=1
Note:The CWM and root files say they are for the i9200 version. They work fine for the SCH-R960
Ok first you need open Odin and plug your device into your PC. If the connection is successful then the box at the top left corner will turn light blue.
Put your device into download mode put hold volume down+home+power until a screen appears, then press volume up.
Click on the AP button and browse to the folder you placed CWM in and choose the file.
Make sure you dont change any settings in odin or check or uncheck any boxes, Click Start
Odin will do its thing and the phone will reboot.
After it passes the Samsung Galaxy Mega screen it is safe to unplug the device from the PC
Let the phone boot.
After it boots you need to close odin plug your usb cable back into the phone.
Find the SuperSUUPDATE.zip file and place it onto the root of either the internal storage or external SD card. (I used the internal storage)
Now you can unplug the usb cable from the phone and power it off.
Boot into Recovery by using the volume up+home+power keys until you see the first screen pop and the release.
You should now be in recovery mode.
Using the volume rockers and power button, choose intsall zip update package
Choose zip from sdcard
Then navigate to where the .zip file is located
When you find it, click on it and choose yes
Then choose Go Back
Reboot System Now
Then you should see a screen that says at the top "ROM may flash stock recovery on boot. THIS CANNOT BE UNDONE.
(These next 2 steps are very important)
Choose "Yes - Disable revocery flash"
Then choose 'Yes - Fix Root"
The device will restart
After reboot, you will see an icon in your app tray called SUPER SU
Don't open it yet.
Open the Play Store and search Super SU
You should see that it is installed but needs an update.
Go ahead and click update.
When you open the app most likely you will get a message that says Binary needs updated. Choose yes.
For the next pop-up choose normal (This step can take a few mins)
After it is completed it will say "Samsung Knox has been detected" choose OK to disable
This step also can take some time if you are on the screen for more than 1-2 minutes close the app and uninstall from the play store and repeat these steps.
Now you should be rooted. You can check this by install an app called Root Checker Basic
I hope this helps everyone in getting rooted.
Anyway to..
Is there anyway I could use TWRP instead of CWM for the custom recovery in this process?? Thanks!

I've only done these steps and CWM isn't my recovery even though it says it passed,I'm still on stock recovery.
Do I continue with flashing SU?
I have the SCH-R960.
Any speedy replies most appreciated.

i tried everything is fine but the SU cannot be updated since my phone wifi is not functional ...
Can't get it to work
I have tried this but to no avail, the update fails to verify every time even following the directions given to the T.
straight talk will not work with u s cellular phone. And there are no roms for the mega that I am aware of.
This method work with other galaxy mega 4.4.2 different carrier ?
Question this work for mega i527 4.4.2
I was told that for Galaxy Mega Sprint L600, root and SIM unlock is only possible if Android version is 4.2.2. Now my question is, does this method work for L600 that's on Android 4.4.2 too?

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).

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...

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.
