Hi guys,

I'm in a rather odd predicament. I've got a completely stock exynoss S20 ultra that has never been rooted. It has recently got itself stuck in a boot loop where it will start up and then sits on the lock screen. It can be like that all day until I unlock it and it has the starting up scroll bar on. After a little while it will then fall into a boot loop. I don't believe I turned USB debugging on as I've never felt the need to root the phone.

I'm currently unable to get the photo's and videos off my phone. Everything else is backed up. Im pretty sure a factory reset will fix my boot loop issues but I'd like to recover my data first.

I was wondering if I could use odin to flash the twrp recovery. Then connect my phone to get my data off and then flash back to the stock recovery and do a factory reset.

As I can't get into my phone due to it boot looping right after unlocking I can't turn on USB debugging nor can I enable OEM unlock.

What would be the implications of doing so, will it trip Knox even if I dont boot into the OS?

All I want to do use Odin to flash TWRP, grab data and then flash back to stock.

Thoughts?

Cheers,

Coddeh
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] GeeAyeZee:
flash a vbmeta file by itself in odin in userdata slot
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] Coddeh:
Thanks for the help GeeAyeZee. vbmeta would be a verified boot file right?

Are you thinking that would fix the bootloop issues?

Or are you suggesting that would be a step to do before flashing TWRP?

Sorry I need more elaboration on what you are suggesting.

Cheers.

i install twrp with s20, ui 3.0 is okay.

but when i load android 11, UI 3.1 , its bootloop when installed Twrp :((

Pls, some one else help me? My device is S20+ 5G
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] GeeAyeZee:
Sometimes when my phone doesn't boot up properly I flash the vbmetadisabled file from in the S20 how to root guide here on XDA. Just put the file in the user data section of Odin and flash it either with your firmware or just by itself works too

[Galaxy EXYNOS S20 S20+ S20 Ultra Development] Coddeh:
Ah that's interesting I assume if it doesn't work for me I could then flash a vbmeta file enabled to bring it back to stock?
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] Coddeh:
Well I tried the vbmeta flash in the user data slot but got an RQT close error due to OEM not being unlocked. I imagine this would cause issues for flashing TWRP as well?
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] GeeAyeZee:
yes you need to unlock your bootloader
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] Coddeh:
Yeah that's what I was thinking and unlocking my bootloader would wipe my data anyway which is what I'm trying to prevent.

Looking more and more likely that my data is gone for good it seems?
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] GeeAyeZee:
most of it will download because its backed up to your google account anyway
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] Coddeh:
Everything is backed up other then my pictures and videos as I use my phone for work and cannot have any work pictures on the cloud. That's the data I was trying to save but seems I may be able to get it back after a factory reset with some clever software on windows or disk digger etc...but something that doesn't require root access.

Follow the instructions on the rom you are using. Use the attached vbmeta.zip and TWRP file from IMcd. Both these files must be packed together according to this instruction into a .tar file.

I do not attach the file because I do not have this option, but the implementation is simple. I did it for the first time and it worked.

Edit.

TWRP is in post #1

[Galaxy EXYNOS S20 S20+ S20 Ultra Development] skysurfer1111:
You can install twrp with odin, but you can't backup your data without wiping, cause the partition is encrypted.

Yes, it still works. Take this TWRP from ian. The .tar includes also the vbmeta.

Flash the tar with odin in the AP field and reboot immediately in TWRP holding pwr + vol up (takes a while, don't release until you see twrp). DONT BOOT INTO SYSTEM!

Why not? Did you flash the latest TWRP +vbmeta like mentioned in the guide?

I uploaded the latest IAN-twrp-z3s-3.5.2_10-A11_6+vbmeta_DUB5.tar here

Additional points are extremely important:

Before flashing TWRP disable ‘Auto Reboot’ in Odin.

When flashing is finished, hold the Volume Down and Power keys to force exit Download Mode. (Important!)

As soon as the screen turns off, QUICKLY hold the Volume Up and Power keys - keep holding the keys and release them once you see TWRP boot screen.

Note: This part is extremely delicate and if done wrong, you might have to restore the stock firmware and re-attempt the TWRP installation again.

Hello my friends,

are you searching for a working recovery to install zip files, but TWRP is still down and outdated?

For now you can use Lineage Recovery from this Thread: https://xdaforums.com/t/rom-unoffic...s-18-1-for-samsung-galaxy-s20-series.4225013/

To install it I did:

1. rename lineage-18.1-20210521-recovery-y2s.img to recovery.img

2. compress it using lz4 so it is now called recovery.img.lz4

3. tar it up to recovery.img.tar

4. install via odin in the AP slot
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] kemick:
I'm looking for install TWRP on a newer Rom than *DUB5, sorry i'm not very interested by lineage recovery but i even will take a look.
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] loxub:
Dear sir, how can i compress something into lz4?
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] DonRichie:
On Windows:

1. Download lz4 win64 zip from here: https://github.com/lz4/lz4/releases

2. unzip into your favourite directory

2. Then Press Windows + R -> type "cmd" and press Enter

3. type "cd <directory where you extracted>

4. type "lz4.exe -B6 --content-size imagefile.img outfile.img.lz4"

On Linux:

1. Install lz4 using your package manager

2. type "lz4.exe -B6 --content-size imagefile.img outfile.img.lz4"
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] loxub:
I did as you said, but when I try to flash it with Odin, it says the compression is invalid.

I found this argument and it worked with Odin: "lz4.exe -B6 --content-size recovery.img recovery.img.lz4"

But once I get to the recovery, when I tap "Install update", it gives me an error saying "error opening /storage/emulated: permission denied".

I think it is due to encryption, but I don't know how to proceed
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] DonRichie:
Yes you are right, I also used those options. I edited my previous answer accordingly.

Unfortunately I can't give you an answer directly out of my knowledge what you need to do now, but for TWRP I also found out that it is possibly an encryption issue.

Possible Solutions:

- Use an external microsd card to read the zip from there

- Wipe Data in recovery

- use "adb sideload" in recovery

Wiping data of course erases all of your data.
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] loxub:
I will see what I can do and follow your tips.

Sorry to jump in on this thread like this but it seemed like the most relevant one for the problem I'm having..

Basically I've got an S20 Ultra and I believe I have used Odin successfully to install TWRP because Odin stated it was passed.

I am moving onto the next step of what I want to do and that is get into TWRP recovery mode so I can flash some ROMs.

I have followed the steps of required key presses as stated in this attachment below, but it just doesn't work for me:

This is sceengrabbed off a youtube video and I followed the visual steps of key presses on there too. I have tried with phone plugged in and out - but no luck.

Does anyone know if this is the correct method? Is there a way of me checking if TWRP actually is installed even?

Incidently, I have no clue about adb/fastboot/powershell, and I'm trying to do all this via the phone and TWRP. But I am open to learning.
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] jaccydan:
Managed to do the key presses to get into TWRP. I flashed Lineage and Magisk, now can't get the phone off of this screen - but can get back into TWRP.

Does anyone know what I need to do to fix this? Thanks.
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] paul c:
I'm not sure if twrp works with Lineage. I thought you had to use the lineage recovery to flash lineage builds.

I know twrp works for eg BeyondROM
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] jaccydan:
Thanks for the info Paul. I have no idea how lineage recovery works so will have to look that up.

However, I have managed to soft brick my phone now and can't turn off the phone (in order to key press into standard recovery mode), and it looks like TWRP has gone as I can't get into TWRP recovery.

I have the stock firmware downloaded. I know I probably shouldn't but, I am currently trying to flash this via Odin on this screen and not on the Download/Odin screen - hence the progess bar at the bottom of the phone. The problem now is the installation has been stuck in this position for about half an hour and I need to find a way of terminating the process (can't see a way to do this in Odin).

I have no idea what to do now to fix this phone.

Any suggestions? Thanks.

Note how the ROM I tried flashing before has now given me an 'OEM Lock' of ON - when it was actually Unlocked and grayed out in Samsung Settings before. Don't know why that happened and if that is the reason why I'm stuck on this screen. This is why I feel I need to try and find a way of installing stock ROM and starting over again from scratch.

I can do a hard turn off via Pwr Key +Vol Down, but it just reboots back onto this screen and doesn't actually turn the phone off.

I will probably just kill Odin in task manager and see what happens - can't get any worse! :(

Hasn't helped that this phone is a Hong Kong variant.

Any help much appreciated.
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] jaccydan:
Well cancelling that process didn't help much. I now have this screen:

My log files are on the right and the youtube video is left. He has it on SYSTEM, whereas mine is on SUPER. I have been stuck where it is on halfway for the last hour. Going to give it a a while longer.

When I watched this video he got his to work. Perhaps because my OEM is locked (as previously displayed)?

I previously tried to install the Smart Switch software (as it says on the screen) and it totally wrecked my Windows, to the point where system restore could even sort it out.

I am running my PC now with little care as I will have to reset it anyway at some point - so I will probably try that Smart Switch route again if this process fails/continues stuck. The only thing is that with the Smart Switch route you need the phone serial number and I don't have that because I got this phone 2nd hand with no box and obviously didn't think to note down the serial number from within the phone settings before playing around with it.

Basically I have a brick right now, and can't think of any other ways to try to sort this out.

Any suggestions most welcome.
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] jaccydan:
Perseverance paid off. I followed the procedure outlined in the previous post and actually used the correct flash files this time. My phone is now back to factory settings.

I would still like to de-google my phone however.

paul c commented earlier:

I will ditch Lineage in this case and look up BeyondROM because I like using TWRP. I have to reset and rebuild my PC's apps, files and folders first (due to that bad Smart Switch program messing the whole setup).

I would welcome anyone to give me any tips and/or links in my attempt to mod my phone - (s20 Ultra SM-G9880 Hong Kong)

Thanks.

Please, does anyone know if there will be an update soon to install TWRP on roms newer than *DUB5 ?
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] paul c:
Good to hear!

I would prefer Lineage too in principle, but there are Samsung-specific hardware questions which for me at least mean that a ROM based on Samsung's is the most appropriate. For example, Samsung's camera app uses a lot of wizardry with which a 3rd party camera app cannot compete.

Anyway, another good reason for using BeyondROM with Twrp is the fact that Twrp will take a backup of our Super partition (afaik, the Lineage recovery can't do that). I always like to have a fresh backup before flashing, just in case things don't work out.

That said, the downside of using a Samsung-based ROM is the limited customisation available
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] jaccydan:
That's good info paul, I'm very interested to use BeyondROM - I think I need to look at some potential youtube vids on it first to familiarize.

I have reached out on this forum thread, to see if anyone can give any advice/links:

https://xdaforums.com/t/rom-beyondr...g981b-g985f-g986b-g988b.4203109/post-85193895
