Samsung Galaxy A20 October Security Update - Android Q&A, Help & Troubleshooting

Hi Guys
I've rooted and installed TWRP On my A20(A205F) successfully.
Yesterday I decided to check for updates and I found that the A20 now has an October Security Update.
[I'd also like to state that I haven't been able to patch my boot.img in Magisk, It failed to download the Magisk v20 Zip all the time, so I got it from somewhere else and tried to get it to work. Eventually it worked and managed to download the zip and patch my boot.img for october update but once I tried it again it keeps failing to download the installer zip.]
So I downloaded the whole firmware and did a full on backup of all my stuff then I proceeded to flash via odin the updated firmware. I've managed to get Root via Magisk working 100% but then I went on to flash TWRP and came out with a bootloop, actually I've tried multiple ways to install TWRP and Magisk without a successful outcome I've now come back to the June Update so I got Magisk and TWRP back.
Some links on the Github page of Magisk isn't working??? Whats up with that? I couldn't download anything from there.
So is there anyway someone could help with getting the update and having TWRP and Magisk working again?

Is is possible to update with TWRP?

Hello,
I have received last week a notification about the new update (from 31th May). Once the file was downloaded, my device has rebooted and arrived in the TWRP recovery. Nothing happened. I checked where the zip file was and I tried to install with TWRP but without success. TWRP said me that META-INFO is missing in the zip file. Is there a way to update with TWRP or have I to wait a new complete ROM with this update?
Thanks
Worked for me,
Which version of TWRP do you have?
It is the 3.0.2.1.
The exact message is "Could not find 'META-INF/com/google/android/update-binary' in the zip file.
Not working take a look at TWRP site I also tried with 3.0.2.1 and after error update is automatically erased.

Thank you Mr. Claude... effectively, with this FAQ on the TWRP site I understand now why it is impossible to apply an OTA update with TWRP.
Have a nice day
You're Welcome. Also on my LeTv x600 worked with TWRP but is not identical update system like P9000.

For me OTA update worked just fine on the P9000 with TWRP 3.0.2-1
only had to flash SuperSU again after the update.
Hello sundawn,
Can you just explain how you made your update? Have you a link to download the update.zip with the META-INF missing ?
Thanks.

Are you sure there was OTA update (with stock ROMs and from Update menu) not regular ROM download .zip made for TWRP and update through TWRP?(in this case you need an TWRP update zip).
There is 4 methods of update of ROMs:
1. OTA (On The Air) in this case updates is downloaded automatically or no (depending you're settings) direct on phone.
2. Download update.zip and flashing from stock recovery.
3. Download ROM.... update.zip for TWRP and flashed from TWRP.
4. Full new update ROM.zip and flashing with SpFlashTools.
Edit: Today successfully managed to update latest OTA 31.05 (but only this because seems there isn't a full update) via TWRP 3.0.2.1.

Same here.
After getting the update notification, I just taped apply and TWRP actually started the update.
Could be you have to remove the sd card, move your SIM from tray 2 to tray 1, and then try updating with the OTA again. That worked for me, after getting errors trying to update with the sd card inserted.
Hi, please, I installed some OTA update and forgot that I have TWRP. And now phone will always boot TWRP. Does somebody know where update is downloaded so I can install it?
Thank you
why make something so difficult? i would just give up on otas if i were you, ive never received any of them, just update manually.. download the file, grab a cup of coffee, and install it
I have the same issue, would like to know how what to flash to recover from this, TWRP for me is working well, but I can not boot to anything else.

Full factory flash with SP Flash Tools was the only way I was able to recover, at least I became very practised at it.

S9+ no boot

I flashed twrp and installed magisk successfully. However I entered magisk and it asked me to update via direct method which I did. Then the phone restarted I got this error... I can boot into download mode but not twrp. What should I do ? Thanks
I fixed it..just reflash firmware using Odin. Bummer now I have to wait 14 days again basically

Root oneplus 7t Pro

I wanted to update my one plus 7t pro but I don't know why even if I used the incremental update I don't have anymore the root. Now I have the following build: Oxygen OS 10.0.8.HD01BA (Europe).
The problem is that I didn't find any patched bootable .img for the version 10.0.8HD01BA.
Is it possible to root my phone with version 10.0.8 or I need to go back to version 10.0.7, root it and then again made the incremental update?.
Thank you in advance.

You don't need to revert 10.0.7 to root, you can use this guide to root 10.0.8 -> https://forum.xda-developers.com/7t-pro/how-to/10-0-3-patched-boot-image-oneplus-7t-pro-t3986351

Also, after downloading the update, don't press reboot.
Go to magisk manager and select install and pick install to inactive slot wait till it's done then reboot.
Always remember to disable modules that could make your device boot loop and restart your device before doing the update process
If you do it this way you don't have to keep making or asking others for patched images and have to use your computer

Question OTA Update for rooted Nord2 5G without TWRP ?

Hello,
Is it possibly to OTA Update a rooted Nord2 5G (DN2103) without TWRP without data loss ?
I rooted it with patched magisk boot image with DN2103_11_A.14 found here on XDA.
Tried OTA update for SN2103_11.A.16 from the phone menu, but got error from updater:
"Could not update: Verification problem" (translated by me, the original english message may be different)
I reverted to stock boot.img but the update fail again with the same error.
Now I am back with the magisk's patched one with root.
Which scenarios I have to update to the A.19 without lost data and without need to install TWRP.
Thanks.

Perhaps I am a bit late to respond, but for future users running into this issue (including myself lol), you first need to install TWRP, otherwise the following instruction won't work. Since you're rooted, you can install TWRP as well (and its really not hard to do)
for DN2103 you have to download the OTA update zip, boot image and vbmeta, see:
[STOCK][DN2103][EU] Incremental update packages & Boot images
Hi All, Below you can find a couple of incremental update packages that you can use for updating from various versions of your device. Incremental update packages These can be installed using TWRP by following this tutorial...
forum.xda-developers.com
After you downloaded the correct files, do the following:
boot into TWRP and flash the boot image corresponding to your update.
(optional) by flashing the boot image, you lose root. to prevent that, you can patch the boot image first with the magisk app. you can always do this step after updating, in case you forget it.
!!! some updates do not have boot image.
flash the <ota_update>.zip
flash the vb.meta image
reboot phone normally
Also, before doing all this, i recommend (temporarily) turning lockscreen security off, in case something goes wrong, you can always recover data then since the phone won't be encrypted.
Thank you, for the answer.
This is the correct way to do update.
Best,

Honor 10 Magic COL-L29

Good afternoon. I ran into a problem that I can not install magic on the device. This requires installing TWRP, which has not been officially released. There is an article on this forum that you can install TWRP, but if I do this, the phone goes into an endless TWRP download - https://forum.xda-developers.com/t/recovery-bkl-emui-8-x-unofficial -twrp-3-2-1-0-working-recovery-from-view-10.3798751/
Version - 3.2.1-0 does not work. I tried iterating through the versions and found 1 which opens TWRP but it doesn't work properly - https://forum.xda-developers.com/t/root-emui-9-0.3883991/. It doesn't clean up, it doesn't install. Some errors in the logs.
I also tried through this instruction - https://4pda.to/forum/index.php?showtopic=904618&st=6220#entry89786439
Next, I tried to find the firmware for this phone, which is extremely difficult. Android version - 9.1.0.xxx
I need this in order to pull out the boot file from there and patch it through the magic. I found the firmware from Colombia. I'm trying to install via HuUpdater. He tries to install 3.2.1-0 TWRP, which does not work, and install the firmware through it, which also does not work. I installed another TRWP where it runs but nothing works. Through it does not want to be installed. My bootloader is unlocked.
I no longer know how to get root rights.
Several times I was able to get root rights, but I could not do a factory reset and the magic did not work properly. It's critical for me. I need to be able to do a factory reset.
Help me please.
Hi! You tried to get the boot.img from your rom, and patched it with magisk, and flashed it to the phone?

I can't do this because this requires a TRWP which is not in working order.
