Just a small reminder: With latest versions you no longer need to manually recompress magisk patched files. App now handles it automatically.

v1.7.0 (https://github.com/Gabriel2392/ErosFlashTool/releases)

This version comes with a new icon to avoid being struck by S4msung (Thanks @ZG089)

Please do not share any older versions that still use the Odin icon, and update to latest version ASAP

Maybe soon? (EUB, aka Exynos EDL) on Eros

New update: version 1.7.5
Get it at: https://github.com/Gabriel2392/ErosFlashTool/releases

Changes:
-> Updated libusb to 1.0.28
-> Introducing EUB mode (Exynos only)

EUB IS EMERGENCY RECOVERY (aka EDL)

Of course this comes with a cost: Limited support.

Devices older than 2016 (including some 2016) was not brickable via software in our tests, thus support was not even added.
Devices released around 2013 and older uses MicroSD booting so is not supported either.
Support will be added from older to newer SoCs. Simply because they are more common to get bricked.

Quick tutorial:
1: Load all 4 slots from your stock rom (BL, AP, CP, CSC)
2: Click start and wait
3: It should now boot into download mode
4: Click start again

I will only add support for SoCs if they were properly tested. So if you have any non-supported SoC but can test, contact me;

Fully supported (v1.7.5):

— Exynos7870
— Exynos7880
— Exynos7885
— Exynos7884B
— Exynos7904
— Exynos8890
— Exynos8895
— Exynos9610
— Exynos9611
— Exynos9810
— Exynos9820

Chipsets and devices they were tested on:
7870 -> J5 2017
7880 -> A5 2017
7885 -> A8 2018
7884B -> A10
7904 -> A40
8890 -> S7 Edge
8895 -> S8
9610 -> A50
9611 -> A51
9810 -> S9+
9820 -> S10e

* Support exists but is disabled. Might be re-enabled in future versions (NOT YET ADDED):

— Exynos 3830 (850)
— Exynos 9830 (990)

* To be added (NOT YET ADDED):

— Exynos 2100
— Exynos 2200
— Exynos 1330
— Exynos 1280
— Exynos 1380

* Yet to check (NOT YET ADDED):

— Exynos 2400
— Exynos 1480
— Exynos 1580

Well, if you want any of the later SoCs to be added faster, you can consider donating to speed up the process. No one with newer SoC is willing to brick their phone just for tests.

Remember, this list is for EUB Only! Normal mode still works in all models

Useful? (device info)

As some requested on the chat, i'm happy to announce:
Eros is now officially available on Linux (amd64/x86_64/x64)

https://github.com/Gabriel2392/ErosFlashTool/releases/tag/180L

How to use:

=> ./eros-amd64 -b BL_xxxxx.tar -a AP_xxxxx.tar -c CP_xxx.tar -s CSC_xxxxx.tar

Or

=> ./eros-amd64 --BL=BL_xxxxx.tar --AP=AP_xxxxx.tar --CP=CP_xxx.tar --CSC=CSC_xxxxx.tar

Example for custom recovery:

=> ./eros-amd64 -a myrecovery.tar

Full help:

Options:
  -b, --bl <file>                  BL (Bootloader) file.
  -a, --ap <file>                  AP (Application Processor) file.
  -c, --cp <file>                  CP (Communication Processor/Modem) file.
  -s, --csc <file>                 CSC (Consumer Software Customization) file.
  -u, --userdata <file>            USERDATA file.
  --slot <A|B>                     Target slot (default: A).
  --no-autoreboot                  Disable automatic reboot after flashing.
  --erase-userdata                 Erase userdata partition.
  --tflash                         Set T-Flash mode.
Note: At least one firmware file (--ap, --bl, etc.) is required.
      Arguments can use '=' separator, e.g., --ap="My file.tar"

Requires: Any distro released after 2020 should work. Tested on Ubuntu 20.04 & Arch Linux 2025.05
If you find any glitches in the commandline, you can ping me on the group chat.

Another little feature planned for next version: Reboot to download

!! AD for new project (PC, NOT MOBILE) !!

Hello everyone,
As you may have noticed, the development for Eros has been inexistent lately.

The reason for this is that... Well android development hasn't been really good lately and i don't want to continue the project on this codebase.
Instead i've been working on a REAL Odin alternative, not something just to help you at the worst time.



So now i introduce Brokkr, the real beast (for PC). A fully open-source rewritten engine.
- First of all, yes it supports multi-device flashing and pretty much everything Odin3 does.

Where it destroys Odin[3-4]:
- Multi-platform (Release currently attaches Win/Linux/MacOS for both x86_64 and arm64, but you can build yourself for 32-bit OS)
- Integrated Wireless flashing (For your Galaxy Watch, cuz NetOdin is shit and legacy anyway)
- But obviously it also supports USB flashing lol.
- Compressed download support — here you'll see up to 2x flashing speed up compared to Odin3

So if you're interested:
!!!!!!!!! THIS IS A PC APPLICATION, NOT MOBILE !!!!!!!!!
Github: https://github.com/Gabriel2392/brokkr-flash
Our community (hope it grows soon): https://t.me/BrokkrCommunity

PS: I remember last year there was a dude who had many tablets of same model. Hopefully you'll find out to this message and help us.

Hi again!
Brokkr is officially replacing Eros on Android now. A fresh new engine with all goodies from desktop version.

First Eros upgrade in almost a year.
The UI is still the one you already know very well. Backend is fully replaced.

Note: For older devices, staying at legacy Eros is recommended as you're not gonna have any benefit from the upgrade and it might introduce problems for these legacy devices.

Initial stable release for Android (and obviously but already stable Windows/MacOS/Linux):
Github Release

This channel will now be renamed and community group will be attached back to it.
