📢 Z3X SamSTool EUB Update – Full Story in Simple Words (Real Talk Version)
Hello brothers,
Many people ask same thing —
“Why Z3X update is slow?”
“Why EUB tool is not working in all phones?”
“Why they release early if it not complete?”
Let me explain.
I work with tools, and I see what happen from beginning till now.
I tell you everything in simple way — like we talk face to face in repair shop.

✅ Z3X Team – Who They Are?
Z3X is old and trusted team.
They not steal tools.
They not buy solution from other team.
They always do own research, own testing.
That’s why their updates take time, but when tool come, it work good and no headache.
💡 What is EUB Mode?
EUB = Emergency Upload Mode
It is new Samsung mode like Download Mode, but more protected.
In new phones, flashing or unlocking need this mode.
Tools like Z3X, Chimera, Pandora use EUB to:
- Remove FRP
- Flash firmware
- Repair boot
- Unlock device
But problem started after Samsung change security...
📅 Story Start in October 2024
From October 2024, Z3X start making solution for EUB mode.
Plan was: release update in January 2025.
But it not happen. Why?
Because:
- Small team — most developer working on Pandora
- EUB mode very hard — need real testing and deep work
- They want stable tool, not buggy one
So they delay... and keep working.
🔒 May–June 2025 – Samsung Changed Game
In May 2025, many phones stop responding in EUB.
Some connect, but nothing happen. Some not connect at all.
Then in June 2025, Samsung lock EUB mode 100%.
Tool connect but cannot do any operation.
❓ What is Lock? What is Efuse?
Lock: Samsung block access through software
Efuse: Permanent hardware fuse. If blown = no tool can fix.
👉 Good news: Samsung not use efuse yet
So maybe tools can still enter by other method
💥 Why Z3X Released Early?
Because they know…
If they wait more time, most phones will get June update — then tool not work at all.
So they release early — even if update not support all models.
Some phones worked, some not. But better than nothing.
🤔 Why Not Inside Pandora?
That part is confusing, yes.
They released as separate tool, not inside Pandora.
Many users got confused. But maybe they did it quick to save time.
Also maybe because Pandora code was not ready to add this function.
Still, they should add in same tool in future.
🔨 What Happen Now?
Now many teams working on this:
🔹 Octoplus — maybe next 1 month they release EUB update
🔹 CPT Tool, FRT Tool — already support boot repair, FRP coming soon
🔹 My tool — coming in November 2025, boot repair ready ✅, FRP and unlock still testing
We not want to copy other tools.
We want something better. More stable. More features.
💬 Real Talk from Me to You
Brother, we are all same.
We spend credits. We wait. We test. Sometimes tool work. Sometimes phone dead.
Z3X maybe delay, but they honest.
They don’t fake anything.
They don’t sell stolen work.
They release what they test properly.
Yes, it slow…
But also real.
🔚 Final Summary
- Z3X working since Oct 2024
- EUB update delayed due to small team, Pandora busy
- Samsung lock EUB mode in June 2025
- Z3X release tool early to help users before EUB gone
- No efuse used = still hope for future
- More tools coming soon with full support
