Entering fastboot mode...

Hey guys,

I am trying to reboot to Bootloader. OEM unlocking is enabled. I am holding the Power button and Volume Up to switch to Android Recovery. Then I have selected Reboot to bootloader, but the device is switching to Entering fastboot mode... What has been changed?

Using the Exynos version.

Thanks.

UPD:

I have used the USB method to launch Download mode. Hold Volume Up and Volume Down buttons and then connect USB cable (which is already connected to my PC).

YES! wasnt thinking straight, everything was just in front of me. Big thanks to dr Ketan!

I got to fastboot mode too, but just entered adb reboot recovery, it should work

Good day [MENTION=3931450]dr.ketan[/MENTION]

Is included Patched Kernel optional or a must?

Would patching the AP file be enough if I do not have problem with using combination key to boot to root?

Thanks,
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] brixkoehh:
My phone just doesn’t feel right without being rooted. Pls help :(

My problem is, It won't "pass" in Odin and gave me this error on the screen of my phone " SW REV. Check FAIL (VBMETA) DEVICE: 0x1, BINARY: 0x0 "

I followed the instructions again and able to get the kernel for my device (boot.img) from the magisk_patched. Maybe this time is different.

Could you please have a check and run it again? Here you can download the kernel for my device

Thank you! [MENTION=3931450]dr.ketan[/MENTION]

What is your devices? You mean you are getting error of vbmeta when you flashing Magisk patched AP file?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] inningsdefeat500:
So just to be sure, for N9860 - I start from Unlocking Bootloader? or everything what it says from the beginning like Preparing Root file
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] brixkoehh:
Yes, I think so. My device is Samsung Galaxy note 20, and the model is SM-N980F. (I attached my device software information below)

Also, is there a way to flash your rom without getting through these steps?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] interestingkid:
Is there any hope of rooting for snapdragon variant?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] inningsdefeat500:
For now, the HK Version - N9860

For North American one - maybe in 2-3 years
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dr.ketan:
Exactly. Only difference is you need to use kernel for your device
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dr.ketan:
If you getting error in flashing Magisk patched file that you have sent patched AP file with magisk then it means bootloader is not correctly unlocked. Read OP and see what you have missed

My rom is for N986B
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dr.ketan:
If time permits, later today I will re write instruction about flashing twrp and patching kernel yourself.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] brixkoehh:
I'm sure I did everything right. It's just couldn't pass through

Okay, thanks.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] interestingkid:
what about for the Korean variant?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] inningsdefeat500:
So I can never install Magisk then?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dr.ketan:
Guys,

OP is updated for Rooting guide for any N20 variants (with unlocked bootloader) with self patching Kernel

Also updated how to properly install TWRP (In case of it is available for your device) with detail steps.

Now there won't require to wait for patched kernel but you can do it yourself.

Thanks
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] crazy4everX:
Works great for the HK Version - N9860 version, a bit of confusion the way it was written and missed the remove "auto boot" after patching but it works now.

After installing the magisk manager i can confirm magisk was installed and granting permissions. Tested "Adaway", seems to be blocking the ads.

Thanks for the work!
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] inningsdefeat500:
Thanks Ketna, so no more special instructions for N9860 - i.e, downloaing this http://www.mediafire.com/file/8u1c2i3iyu96fxe/file

BTW, my N9560 says its	N9860ZSU1ATH2 but all the N9860 firmware out there is	N9860ZSU1ATH1, there is no TH2 - will this be an issue

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dr.ketan:
You don't need to download any kernel as said on older guide. New guide showing how to prepare yourself. Only magisk/twrp (if available) and stock firmware you needs to download
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] inningsdefeat500:
B.Preparing TWRP :

Download TWRP for your device from Here. - The link says TWRP is not for Snapdragon ( including HK Version which is N9860 ) - https://xdaforums.com/galaxy-note-20-ultra/development/recovery-twrp-galaxy-note-20-note-20-t4152335

So what do I do here?

How abt TWRp?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] inningsdefeat500:
Please HELP

So ODIN failed for me, I tried to reboot device from there

Now I got

An error occured while updating the device software
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] brixkoehh:
I tried both with and without TWRP. It's still not working for me. This is honestly so tiring and frustrating

:crying:
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] inningsdefeat500:
What Firmware did you download ?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dr.ketan:
If twrp not available then you needs to root without twrp as shown in OP

Request twrp developer to add support for your device.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] inningsdefeat500:
Thats fine but I cant get out out of this, as ODIN as FAIL'd

Can I bring it back to factory default?

Am I screwed?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dr.ketan:
Nothing I can read in img you posted
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] inningsdefeat500:
Ketan, so I followed instructions and ODIN failed

I am now stuck at An error occured while updating the device software

I can however reupload via ODIN but then it fails again

I cannot reboot device as it comes back to that error

Can you please help? can I put orginal back? if yes, what steps or any other help please

JUST FYI - Mine is SM-N9860 and I had posted earlier but got no response - My model says N9860ZSU1ATH2 but all the N9860 firmware out there is N9860ZSU1ATH1, there is no TH2 - will this be an issue

I downlaoded from https://www.sammobile.com/samsung/g...e/SM-N9860/TGY/download/N9860ZSU1ATH1/362419/

Please help - else I am down $1800
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dr.ketan:
What stage odin fails? Show me clearly picture of odin/screenshot

Possible you may have received OTA for TH2 and yet not available as full firmware. Sometimes Samsung put restriction about downgrading and that may lead to fail. Usually in modem. In that cause you need to to wait till TH2 out
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] brixkoehh:
Like I said the magisk_patched is giving me vbmeta errors. So what I did instead was, I only flashed the patched_kernel, and It worked. My phone is now rooted.

But the problem is, when using Titanium backup, I can't uninstall bloatware/system apps. Any idea why? [MENTION=3931450]dr.ketan[/MENTION]
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] inningsdefeat500:
While I was waiting for you reply, I tried to install the original N9860OZS1ATH1 and THANK GOD it PASSED

So coming back to your reply above - I wish I had taken the screenshot but it was right at the end - I mean I would have to perform a risky try again for that screenshot

As for the s/w, you are probably right about the OTA - actually the phone was completely updated when I got it but how did it remain in TH2? when I just uploaded downloaded Firmware from SAMMOBILE which is TH1? I didn't take any OTA update now?

So, I checked again, here is a screenshot - I was always looking at Baseband but now reading the s.w it says N9860OZS1ATH1 - unsure if this changed now? or was it like before?

Another thing is I don't have OEM Unlock option in Developer mode anymore but I did before I tried to root and it was greyd out after that too?

I checked in download mode now, is it unlocked?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dr.ketan:
It is pre normal and it don't allow to flash custom binary

Search xda for 7 days trick to enable oem. Once it appear and greed you can try rooting again
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] inningsdefeat500:
OK, how about this?

Everytime I do a factory reset or even a normal boot - I get https://streamable.com/s31jm9

I was wondering i I could go to recovery and fix the above? anyidea
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] inningsdefeat500:
So this is interesting, I couldnt tell what that error was in Chinese? and it seems when I installed the stock f/w from ODIN, I only uploaded AP file ( the big tar file ) but not anything else

So I thought of going back to do it properly in Download Mode and this time - the phone asked me "You sure you want to LOCK the bootloader " ? I said YES and now I go back and see OEM Unlocking is there?

WOW - what the hell is going on

Now should I give this a try?

Please confirm this is correct? - https://www.sammobile.com/samsung/g...e/SM-N9860/TGY/download/N9860ZSU1ATH1/362419/

Thank you, doctor Ketan! You are the man. Please, answer 2 questions.

A. How/what to use to backup EFS IMEI?

I don't have the device yet so I don't know if you mean TWRP to do that.

B. Is TWRP capable of making proper backup and restore? If yes, then which partitions must be selected in TWRP backup for a full backup?

We appreciate your constant work here!
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dr.ketan:
Really never tried twrp

I do prefer to make it myself and use that's only.

I have added support for N20/s20 too. But my app is paid app on play store. I am using it and tested and working as it should.

In case if some one looking for free, try twrp or look on play store.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] inningsdefeat500:
Didnt realize you had your own store, will surely buy from there

Any opinion on my post about Baseband and Software, should I root for wait for ATH2 as when I try to see software info - it says I have latest
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dr.ketan:
If you flash only AP then modem won't update

Try flashing only patched kernel (patch kernel as shown in op) with ap tab

My app as of now only supports exynos
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] inningsdefeat500:
So just the patched kernel ( which I patch via Magisk ) in Odin's AP tab - and Auto reboot off?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dr.ketan:
Yes. And then reboot to recovery & format data
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] inningsdefeat500:
I found my error, my boot.img was there as boot.img.img

Now, I tried the complete setup from OP and it passed without issues

Just 1 thing, if Magisk says installed - why do I have INSTALL option next to it?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Brava27:
So let me get this straight... I can root the N9860 (Snapdragon) but cannot install a ROM or twrp on it. Correct? I have the choice of N9856B OR N9860.

Mostly interested in viper4android, titanium backup, fonts, magisk etc... Thanks for the info!
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] inningsdefeat500:
Correct - but worth it sine it can be rooted and TWRP can be available in future maybe
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] matlear:
Followed instructions in OP, all seems to be working well, purchased your EFS backup app and did a backup to gdrive.

Second boot in TWRP its best to have Magisk and Encryption disabler on a OTG, as sideload doesn't seem to work for me.

As I am running Samsung firmware (not your custom rom) , can you share how you enabled call recording, also looking to get samsung blockchain installed if you have any ideas how to bypass region restrictions?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dandingello:
definitely yes, sorry for the late response brother. Just follow dr.ketan's instructions. worked smoothly :good::good::good:
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] fkofilee:
Dr... Just a quick question. Sept Patch etc is out.

With the Kernel you supplied - It cant be flash due to change of base?

How does one flash the latest release with Magisk? Or just go standard (Patch the AP with Magisk etc)?

[Redmi Note 8 Pro Questions & Answers] vruhag:
Hello there,

I have bought a Redmi Note 8 Pro in Europe. My goal is to get a custom rom on it up and running.

The bootloader is successfully unlocked, and I tried to flash TWRP and Orange Fox recovery. To do so I followed the instructions on the TWRP home page to the letter, namely flashing vbmeta.img (fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img) first and then the recovery image (

Sadly the TWRP and Orange Fox recovery never starts; the system just seems to be stuck in a boot loop for recovery, until I power it off and start it in a way that the stock ROM provided on it re-installs itself.

I have tried so far all suggestions I was able to find in this forum, but sadly no result.

What might I still do in order to get a recovery finally up and running on this device?

Thanks in advance!
[Redmi Note 8 Pro Questions & Answers] kekesed97:
Are your flash sequence vbmeta>TWRP>reboot?

Try to flash vbmeta once more.

Also, for recovery, choose one of it.

Disclaimer: I am not responsible for any bricks/ issues you may encounter following this guide. Although, I will do my best to try to help you if something were to go wrong.

MAKE SURE OEM UNLOCK IS ENABLED UNDER DEV SETTINGS BEFORE YOU DO ANYTHING BELOW

Update 2: 3/11/2021 : I see maybe deleting the .ta files may help avoid soft bricking, feel free to try it I have not personally tested yet to see if it works.

Update#3 3/13/2021 : If you are following this guide recently make sure you update to Android 11 first! Do not do any updates after the first one to Android 11! Then the flashing should work just fine. Tested and verified this on Taiwan XQ-AT52 to 51 firmware

Hello, I've managed to successfully flash AT51 firmware on my AT52 without issue using Newflasher.

Step 1 download = the US firmware/ whatever region is needed for you and new flasher/ the sony xperia drivers needed to flash the firmware to your device. Extract it to your desktop. Install the Xperia driver from newflasher if you need to/ haven't yet. Newflasher needs to be extracted into the same folder where the firmware files are that you downloaded from Xperifirm. This step is crucial!

Step 2 : Power off your Xperia and put it in flash mode by pressing down on the volume and connecting it to your PC via usb. (Do not use the USB C cable that came with the phone use a different one if you have one) You'll know it is in flashmode if the notification LED turned green and the screen remains off.

Step 3 : Open newflasher.exe

Step 4: type n then press enter

Step 5: type n again and press enter

Step 6 : This is when you should get to the flashing stage. Press Y and enter to everything you are prompted to. type y for yes to. This for me resulted in a successful conversion over to AT51.

Step 7: Once everything is done and it says you are safe to disconnect your phone please do so and then press and hold your power button until the phone boots up.

At this point you should have a fully working AT51 firmware! :)

Bare with me as I"m working on getting developer access for androidfilehost and will upload the files asap. In the meantime you can download newflasher and the firmware files yourself using Xperifirm if you don't wanna wait for me to upload.

Hi, I didn't find this thread until after I made an attempt at flashing the device. I followed the instructions from the link below and ended up with the device saying it's corrupted.

https://www.xperiablog.net/2018/01/...-firmware-for-xperia-xz-premium-xz1-and-more/

I tried redownloading newflasher as well as redownloading the firmware I wanted as well as a new cable and that did not help. I reflashed it with this procedure listed above and it did not help.

Xperia companion won't let me do anything because it says the device is locked even though the device was not locked and there doesn't appear to be a way to unlock it. edited to add that I did get xperia companion to repair it successfully

edit again to advise I succeeded only after doing n and enter a third time then hitting y and enter for the final flashing step and that was successful in getting it updated correctly

Would it work to unlock my phone

Thanks for the guide!

Can I ask few questions please?

First is do I need to have my bootloader unlocked? I enabled OEM unlock setting in developer settings but that is only one thing I did.

And the second one is could this flash unlock my phone?

I am in this situation where my AT51 won't work with other sims except for Vodafone. UK.

I stayed with them for 30 days, (required time frame to get your phone unlocked) requested unlock code and it has been more than 10 working days but still have not received the code.

So today I did some searching online and found the service code to check if my phone is locked to a network and to my surprise it says it's not. So I am guessing that they have limited my phone to using only their sim through some other means andnot buy locking my modem. But this is ofc just a guess.

I kept chatting with the customer support and he keeps saying wait for the code which I do not believe is going to come, they have to unlock it on their end. But I am not sure about that. I don't think they are sure either..

Basically I'll wait fem more days maybe they will unlock it but if they won't when I am thinking maybe my modem is not locked and I could unlock it by flashing different ROM?

Or do you think this won't work?

Sorry for a rambling post. Looking forward to your reply. Thanks!

Anyone know if you can flash a XQ-AT52 to a XQ-AT51 and then back to the XQ-AT52 firmware?
[Sony Xperia 1 II Guides, News, & Discussion] ProjectBlitz:
I know this thread is a few months old at this point but I'm really struggling to flash to XQ-AT51. I've successfully flashed from XQ-AT52 Hong Kong (my original firmware) to the Taiwan version which is slightly better because of the messaging compatibility but I really want to get the US version. I have tried at least 20 times over the course of a full day and I have not been able to flash the US firmware without getting an error saying "Your device is corrupt It can't be trusted and will not boot" every time. I have repaired it back to the Hong Kong firmware (back when that was the one I had) and to the Taiwan version once I had that installed. But I have never gotten the US firmware to take without the "Device is corrupt" error.

My phone is the Sony xperia 1 mark 2 running the then default XQ-AT52 Hong Kong, and now running the default XQ-AT52 Taiwan. I've been trying to flash to XQ-AT51 US. I've been using newflasher v39 and the US firmware downloaded for xperifirm v 5.5.0.
[Sony Xperia 1 II Guides, News, & Discussion] ProjectBlitz:
So I was able to flash from the hong kong version to the Taiwan version and back with no issues at all.

Can someone make me a favor and can upload the latest ftf of Android 10 for the Xperia 1ii Single SIM?
[Sony Xperia 1 II Guides, News, & Discussion] Ambroos:
The 1 II has downgrade protection, so as long as the firmware version of the US version isn't the same or newer than the highest version you've ever used you're gonna get the corruption error.

What you could try is flashing the newer EU version and then flashing only the older US customisation image. That's what I did for a while since US firmware was older than EU firmware, and it worked. Not sure if it'll work with Android 11.
[Sony Xperia 1 II Guides, News, & Discussion] GreeleyXda:

[Sony Xperia 1 II Guides, News, & Discussion] THISISINSANE:
It's for better coverage and for VoLTE and Wi-Fi calling support. Also if you get a HK one with Android 11 you will be unable to flash the US firmware, because it is still on Android 10; and the phone has anti-rollback protection.
