How do I sign an MD5 file for Odin? - Android Q&A, Help & Troubleshooting

Hello,
I have been trying to install Android 11 on my phone (Galaxy S9 SM-G960U1) for a while. I have realized that in order to flash new firmware onto my phone, it must be signed or the bootloader won't accept it. When I flash non-signed custom firmware, Odin returns an error about authorization.

Only OEMs/Carriers sign Stock ROMs / OTAs provided by them. ODIN works with Stock ROMs only.
To flash a Custom ROM you need TWRP or similar.

I cannot use TWRP without rooting my phone, which will take some time. I will use the Extreme Syndicate method (https://forum.xda-developers.com/ga...pment/root-t4041815/post81608559#post81608559) to root my phone, then install TWRP.

I tried using TWRP, but I got the error:
Security Error: This phone has been flashed with unauthorized software & is locked. Call your mobile operator for additional support. Please note that repair/return for this issue may have additional cost.

ROM options after bootloader unlock & custom recovery installation

I have a Mate 10 Pro BLA-L29 C605, that is stuck on 9.0.0.254 and I'm seriously considering paying $40 to Ministry of Solutions for their bootloader unlock service. After unlocking, I would be installing a custom recovery.
I'm not interested in root, and I would like to stick with the official firmware, so I was wondering if, after a bootloader unlock and installation of custom recovery, I would be able to install a firmware downloaded via the Firmware Finder windows application? It's been a long time since I've flashed ROMs via a custom recovery, so excuse my ignorance if the process has changed, but I'm hoping I can simply download a newer official firmware and flash it via recovery.
Thanks for the help.

root Android Q on s9+

Hello, I updated to Q and can't get it rooted.
It bootlooped.
How can I root Android Q?
visit: h t t p s : / / twrp.me/site/update/2019/10/23/twrp-and-android-10.html
As, if now you cannot. For Android Q, it's still in research.

Never tried but: ClockworkMod Recovery – a past alternative to TWRP custom recovery.

I would recommend you flashing custom firmware, like the one in my signature. Everything is working, including Security Folder.

Which TWRP version you used and how did you install TWRP on a non-rooted phone? Do you not have to use Magisk to root the phone first?

I just used the 3.3.1.1 from the TWRP site.
Flash TWRP is to root, so I did it b4 root.
1. OEM unlock
2. Flash TWRP with odin then boot to TWRP, samsung will restore if u normal boot.
3. Backup EFS
4. Format data wipe all
5. Dm verity, search newest from dr ketan
6. Flash custom ROM.
Magisk usually comes with the custom ROM.

This isn't true I flashed Twrp 3.5.091 via Odin, S9+ exynos android 10, then flashed Magisk 21.4.
When I got phone it was android 10 June 2020 security update. It then updated again to 21/02/2021 ota.. I was able to flash recovery twrp and root/debloat. Only problem I did find is that I cannot flash lineage 18.1 or any custom roms.

hey ,
1.install magisk manager on your phone
2.download the firmware from samfirmware for your model of phone to pc
3.download 7zip with lz4
4. use 7zip lz4 to extract boot img from AP(firmware)
5. send the xtracted boot.img to phone sdcard and use magisk manager to patch said image .
6. send the patched img to pc and use 7zip to create archive as boot.tar file
7. one you install the firmware as normal via odin (disable auto reboot ) go back and disconnect/reconnect usb from phone so it appears as added in odin once more.
8. add the boot.tar file to AP in odin and flash the phone , reboot system and install magisk manager again , go into magisk and it will reboot again to fix the root.
there is a video somwhere on youtube showing you better than ive tried to here.
this is by far he best way as you can still take ota updates because stock recovery is still present .
regards

Unistall TWRP and make ONE Plus 6t like factory-made to claim warranty.

So i was trying to root my Oneplus 6t that was running OXynogen 10.3.4 Android 10 using TWRP & MagicSk.I read a tutorial somewhere explaining how to install TWRP recovery & then flash Magicsk.I successfully installed TWRP recovery on my phone using cmd with the help of fastboot.However, when i tried flashing Magicsk using TWRP,i got an error "KEY VERIFICATION FAILED".Now, i don't plant to proceed with rooting my phone any further.Can someone please tell me how can i undo all of my actions and get my phone back in original condition as it was when i purvhased.Like pure stock android with no TWRP,No unlocked bootloader...Just like a phone's software looks when purchased new.
TWRP can't get uninstalled. You've to flash Stock ROM to get rid off of it.

How do u suggest i flash the custom ROM? Will i have to do it using TWRP? Oneplus gives a .zip file of stock ROM on its website.Also will doing this lock my bootloader again?
@Illicit_Lokesh
I thought I made it clear.
FYI: Recovery and ROM are two completely independent different things.
No one needs a custom recovery as TWRP to flash Stock ROM: This can be done with Android SDK tools like ADB and Fastboot.

TWRP on Mi Pad 4

Hello,
I am a newbie into this.
I want to root the Pad to run some apps that require root access. The bootloader is already unlocked via the miflash unlock tool.
Next I tried to install TWRP 3.4.0.0 via using the guide from twrp.me
https://twrp.me/xiaomi/xiaomimipad4.html
I am able to load the image into recovery section and I am also able to boot into recovery straight after that in order to enter TWRP (using Vol up plus power button as the guide mentioned). But once the Android system is booted up the TWRP bootloader in the recovery section is gone/wiped whatever because the Mi boot menu appears again.
What do I miss out?
It is also recommend to perform a backup in TWRP before rooting (magisk) or flashing a custom rom. The backup fails with a couple of red line "unable to mount...".
Any help is appreciated. Thanks.
You are using the stock MIUI right? MIUI will automatically revert recovery back to the stock one. You have to install a custom rom to retain TWRP.

Correct still using stock MIUI. Sadly, that means root and stock MIUI won't work at the same time.

Although I never use stock MIUI, I think you can root normally. You don't need TWRP to maintain root.

Do I need to flash stock firmware for S7 Edge SM-G935F first, or can I just flash TWRP?

Basically, I've searched for this question but no concrete answer to be found. I am following a rooting tutorial and it says to flash stock firmware through Odin and then flash TWRP.
I have found the stock firmware for my country (Android 8), but other cell carrier than mine, and the phone is currently running Android 9.
Can I just flash TWRP without flashing a stock firmware beforehand, or is it necessary to flash a stock firmware first, and if so, what about the different carrier and a previous Android version?

Before flashing TWRP, it is a good idea to flash the latest firmware to get the latest version of the modem, which will be useful for use with custom ROM.
Carefully read the TWRP flashing instructions so there are no surprises.
If you don't want to change the original firmware, then flash TWRP.
beware, latest firmware may bring new security updates such as vaultkeeper or RMM protection to your device.
you can flash different CSC with modded Odin (not recommended) but you can't downgrade bootloader.
use Samloader or Bifrost to download from official Samsung server for your region.
