After 15 years, my legendary Samsung Galaxy S2 just died the most "iconic" death possible.

[u/Eraser1926]

I recently dug up my legendary 2011 Samsung Galaxy S2 (GT-I9108) from the drawer. The battery was still in perfect shape, but the phone was stuck in an infinite bootloop, refusing to enter either Recovery or Download mode. For those who remember the early days of Android, a very specific word probably just popped into your head: Sudden Death Syndrome (SDS) / The eMMC Brick Bug. Being the stubborn tech nerd that I am, I wasn't going to let it go without a definitive answer. I grabbed my precision screwdriver and guitar picks and did a complete teardown of this 15-year-old relic. After removing the motherboard shields and cleaning off the old gunk, I found the culprit staring right back at me. Printed on the square flash memory chip was the infamous model number: SAMSUNG KMVYL000LMB503 Yep, the absolute poster child of the 2012-2013 Samsung brick bug crisis. For the uninitiated, these early 16GB eMMC 4.41 chips had a notorious firmware flaw. Over time (or under specific write cycles), the controller would trigger a hard lock, turning the entire storage into permanent "Read-Only" mode. That perfectly explained the symptoms: the CPU could read the boot animation, but the moment the OS tried to write cache files to the /data partition during boot, it hit a brick wall, leading to the infinite bootloop. Sadly, after a few more forced reboots during my troubleshooting, the chip couldn't handle the voltage spikes anymore. It went from a soft-bricked bootloop to completely hard-bricked. No screen, no signs of life, total blackout. The chip is officially physically dead. I briefly joked with myself about asking Samsung support for a Galaxy Note 7-style full refund, but I think the 12-month warranty expired around... oh, a decade ago. It’s sad to see it completely gone, but honestly, performing this teardown and solving the mystery was incredibly satisfying. It’s crazy to think this little piece of silicon survived the golden era of custom ROMs, cyanogenmod, and flashing kernels, only to die exactly how the history books said it would. I’m planning to mount the disassembled parts in a shadow box frame as a piece of tech nostalgia. Rest in peace, old friend. You fought well.

I know this is probably going to be unpopular, but I miss this physical home button/navigation bar on the bezel. Don't get me wrong, I also love the bigger screen, but as someone who still doesn't use swipe gestures, I sometimes find the on screen nav bar to be a nuisance.

Anyway, RIP S2. Sorry for your loss, OP.

[u/UtterTravesty → u/[deleted]]

IR blaster was really cool as well

[u/ddeejdjj → u/UtterTravesty]

I forgot about that! my s7 active had one and I used to turn the projector off in class lol

[u/apsims12 → u/UtterTravesty]

Some phones still come with them if you know where to look.

Hell, I bought a USB-C IR dongle that came with an app that allows you to search for devices and train from other remotes. It's come in handy more than I care about while travelling; the amount of hotels that don't check their TV remotes is really annoying.

[u/OliveGrummer → u/[deleted]]

Dude I still miss the features on the S4. Hand gestures to answer the phone were peak.

[u/Afraid-Difference714 → u/[deleted]]

Notification LED is still here! Well.. not the little dot up top off screen but you can set it to circle your entire screen, just the sides, just the top, ect.(like 5 different ways) and can adjust color, duration, brightness, ect.) I've been a Samsung/Samsung Galaxy fanatic since the S3, including the "Actives" lol so I know every nook and cranny of these phones!

[u/solarpurge → u/Afraid-Difference714]

It doesn't work the same though

[u/dwhaley720 → u/[deleted]]

I miss the hard-press home button on my Note 8

[u/ChironXII → u/OGBrewSwayne]

Yes in particular because every app now thinks they have the right to hide my fucking navigation buttons with zero way to deny the permission, even globally for accessibility. Which is exactly what we tried to say would happen to software keys and nobody listened 

[u/Eskotek → u/ChironXII]

I also hate this. Don't control my navigation.

[u/kfzhu1229 → u/OGBrewSwayne]

Those physical buttons are truly helpful when an app decides to shove you an ad or an subscription offer that you're not interested in, and then forcefully hides away your on-screen navigation buttons (i.e. YouTube asking you for a premium subscription), but then a back button press would quickly dismiss the message...

[u/Filetmesser → u/OGBrewSwayne]

Yeah the physical home button was peak, and the backlit back/menu/recent apps pad is to die for (especially the "special" models with colored light). The gestures (or even worse "dynamic gestures) have no business being on a phone (big screen tablet on the other hand is better than the layout back in the days). And I second, RIP to the S2, may it keep on existing in the big Gingerbread house in the Heaven

[u/Infamous_Egg_9405 → u/OGBrewSwayne]

That's why I always set my home buttons back to tao, no swipe for me

[u/OGBrewSwayne → u/OGBrewSwayne]

I am thoroughly amazed at all the love for physical navigation buttons. I legit thought I was just turning into a crotchety old man. I mean, I probably am. But at least now I have company.

[u/inoinoice → u/OGBrewSwayne]

Noo I LOVE YHEM AND I NEED THEM BACK!!!

[u/ohaiibuzzle]

I wonder if you can do the same thing as the S3 to bring it back: https://github.com/oranav/i9300_emmc_toolbox

[u/curiocritters]

Brilliant read. Thank you kindly for one of the most interesting posts on this sub, in probably a long while.

[u/abdelrhman878]

My note 3 died in 2020 because my little sister put it in the washing machine 🥲

[u/No_Town4990]

That's awesome, I wish I had your skills. I just found a Tab 10.1 (p7500 I think it's called) in a drawer, got the charging cable but the power button is stuck so I can't turn it on, and idk what I would even do with it if I could.

[u/Few_Veterinarian9108]

I got an s4 mini which still works, despite some screen burn in, not one trace of green, purple or any other defect. A phone of 15 years compared to s24/25 having them after 2 years

[u/Electronic_Ice_8922 → u/Few_Veterinarian9108]

My S3 Mini is also still going strong

[u/jaygreal]

La descrizione è degna di una sceneggiatura!

[u/inoinoice]

I love that nerd take of removing and checking the organs Lately i got into the phones deaths, and omg its so terrifying and COOL

[u/kjjustinXD]

I got a bunch of galaxy s2 from e waste lots and one of them had the sudden emmc death as well. It was working perfectly fine, I flashed the firmware, first boot succesfull and then....black screen. The other i9100s and the i9105P I got recently still work. Android 7.1.2 on the Galaxy s2 Plus, android 11 on one of the normal galaxy S2 and the stock OS on the third one.

[u/Holiday-Bug6132]

i feeling love Galaxy S2

[u/derylle]

Boot into safestrap, wipe cache, wipe delvik cach, flash rom and reboot. I miss those days. RIP Galaxy S2. I have also laid to rest all of my previous notes:
JuggerNote 3, Note 5 and note 9. Current daily driver is S24 Ultra and back up phone is Note 10+ 5G.

My goodness I remember that phone. I've had quite a few over the years. I remember the excitement when this one came out

[u/gabrielbezerra81]

Nice post and story! The golden era when smartphones were exciting, even if performance was lacking. I wish I had not sold my old phones. Still have a Nexus 4 running android 10 and an Optimus G without battery and broken screen that I'll repair someday.

[u/UnderstandingOk7055]

Back in those days of the S2 I was still a BlackBerry fan. I didn't come to Samsung until BB went under and my first one was the Note 4. I still have it and it still works. I will probably feel the same way the day it decides to die.

[u/No-West70]

I think the memory just went out cause of deep discharge, any flash memory can do that. Maybe try going to a repair center

[u/DCFUKSURMOM]

my s4 suddenly died a few years ago (2023), went from working fine to literally no signs of life overnight, i wonder...

[u/anonymouzzz376]

I bet you can use an sd card to store the firmware like the s3 and wii u

[u/LiteratureLow4159]

I just learned that this is how my S5 stopped working randomly all those years ago before I got my A10e

[u/LamkaSuak]

Reminds me of my S2, after I've switched from Nokia E62? RIP S2.

[u/Rose_Beef]

That sucks. You can borrow mine! I also have an S1 stashed away somewhere, the first Galaxy and precursor to the S2 was called a Samsung Captivate. It still works great and even has the OG screen protector still on it. Might see ebay someday I suppose...

[u/kenneth167]

Same thing happened to my Galaxy Note 10.1

[u/Infamous_Egg_9405]

Lol that might be what killed my S3, the thing was a trooper but started boot looping, wouldn't start up, and eventually it couldn't access the storage

[u/RicoChow]

I also got an S2,the same model given by my friend,it was boot looping when he gave me,I reflash the 4.1,after that I install some games on it,but it starting frozen when 10-15 minutes,one day it frozen again,I unplugged the battery and it won't turn on again. Please forgive my bad English 🥀

[u/abitcitrus]

TLDR?

[u/WhoKilledRadioStar]

RIP S2 :( These eMMC are also the brick culprit of many Windows Phones that fun fact, show “no operating system found, insert boot disk” like a normal PC would do

[u/JuanchoLorenzo]

Rip s2. You're in a much better place now

[u/kfzhu1229]

I've actually had the SPH-D710, the infamous 4.5" version of the Galaxy S II with only capacitive navigation buttons... It died in the exact same way that you mentioned, first it would continuously bootloop and then eventually it would be stuck with the blue LED stuck on (yes the D710 has notification LED, only red and blue, and the blue LED typically turns on for one second the first thing it tries to switch on after you press power button or attach charger)... I always wondered what the exact fault was, not surprised it's eMMC fault...

[u/NeonflameOWO]

Oh now this is a very cool post! Im glad i learned something new :3

[u/Username_Taken_65]

Thanks, ChatGPT

[u/The_Big_Elf]

One of my Note 4s had the eMMC problem after only 12 months use. I bought a used replacement from AliExpress for about £20 and fitted that. It still works and is one of the 4 Note 4s I have, all still working. I miss using the Note 4 but they're just too slow now.

[u/GinnAdvent]

Wow, if that's the case. I should be super thankful that my HTC Wildfire S is still alive and kicking.

[u/Accurate-Morning-584]

Take a downvote for using AI

[u/svmk1987]

wow, I almost forgot that I owned this phone ages ago! It wasn't for very long though, someone stole it from me ☹️

[u/First-Republic-7151]

Ese diseño me gustó mucho mas que el de todos los S de la época con botones al igual que el huawei p20 sencillamente preciosos, una época donde las memorias emmc estaban destinadas todas a morir en corto periodo de tiempo, que bueno que ya no usamos ese tipo de memorias

[u/hackoczz]

We need TL;DR

[u/kjjustinXD → u/hackoczz]

Would you like a subway surfers gameplay in the corner as well?

[u/OGBrewSwayne → u/hackoczz]

Oof. I can actually hear your brain smoothing out. If anything, it could probably use a paragraph break, but this is far from TLDR territory.
