Mine was 0xf1 (insane chip), manufactured date is sept 2012.. started using since Dec 2012 .. my note 2 work flawless without any freeze n auto reboot until now. Was on stock firmware(latest) stock kernel.. n rooted. :D
[Galaxy Note II Q&A, Help & Troubleshooting] adnanhidayat:
note 2 with persues on 4.1.1 and cfw

well....... SDS is really scary. i ve installed perseus and custom recovery in a 4.1.1. m i safe???? have never experienced any restarts or hangs so far. m using it rarely for now. dont like 4.1.2 cz sucks the battery. i wanna b on 4.1.1 but safe from this SDS.
[Galaxy Note II Q&A, Help & Troubleshooting] Simonna:
4.1.1 doesn't have fix to SDS so it's not safe.
[Galaxy Note II Q&A, Help & Troubleshooting] adnanhidayat:
perseus kernel ????/ i guess it has the samsung patch. m i wrong ?????
[Galaxy Note II Q&A, Help & Troubleshooting] madushan92:
Great! I'm on 0xf7 :)
[Galaxy Note II Q&A, Help & Troubleshooting] IT_Fan:
It's not safe, I had been using 4.1.1 and Perseus and CWM recovery before my phone got SDS.
[Galaxy Note II Q&A, Help & Troubleshooting] adnanhidayat:
ok so upgraded to official 4.1.2 dmc 3 + philz+ perseus 36...... how about now. battery is the same. didnt experience any life difference.
[Galaxy Note II Q&A, Help & Troubleshooting] IT_Fan:
not sure, I got mainboard replaced from The Service but still have fx01 chip and I am worrying it will die again in the next few months when I will be out of warranty. Anyway mine has been updated to the latest stock firmware, what only can do now is wait and see.
[Galaxy Note II Q&A, Help & Troubleshooting] Simonna:
To feel a lot safer I would suggest you to use SDS safe kernel and recovery (one of them is Perseus kernel)

And otherwise you can always sell it if you're really afraid of it, so good luck. :)
[Galaxy Note II Q&A, Help & Troubleshooting] adnanhidayat:
thread is dealdy slow. all note 2 died or got safe from sds ? :D
[Galaxy Note II Q&A, Help & Troubleshooting] Bright.Light:
I was under the impression that the latest stock ROM fixed the SDS?

Anyways, my motherboard was replaced and it seems I got the new chip :D
[Galaxy Note II Q&A, Help & Troubleshooting] IT_Fan:
Then you're lucky, I told them I need a different chip to prevent SDS but they didn't believe, not many people believe in SDS in my place.
[Galaxy Note II Q&A, Help & Troubleshooting] joseaugusto1:
May I ask you where did you get your motherboard replaced and how much did it cost you? my note II just died, it just shows like static distortion when I try to boot it up and I would like to repair it. Thanks in advance
[Galaxy Note II Q&A, Help & Troubleshooting] s3ezy:
mine look weird

type: v3w00m

fw: 0x00

n7100

is this ok?
[Galaxy Note II Q&A, Help & Troubleshooting] dlo604:
So I got the SDS 3.5 weeks ago and sent it into repair. They replaced the motherboard no problem. It was interesting though cause I did notice a few things leading up to my particular issue.

1. Battery life was not nearly as good. Yesterday and days leading up to my screen just never turning on again, my battery life was absolute ****. I would only get 3.5 hours max with screen time on. I ran a test yesterday and I was getting my normal battery life of close to 5 hours (screen time on) so that's a huge relief.

2. My phone was going haywire and it would always reboot itself a few days leading up to the SDS. I don't think I'm going to root this phone again at least not using a Mac. Not sure why the support for rooting devices with Mac is really shifty compared to Windows... Hope this changes in the near future... Doubt it will though

I just got my phone back and I will continue to monitor the progress. Oh and it took me 3.5 weeks to finally get my phone back. Does anyone know if my warranty renews itself once I have sent it in once or does it not??

Thanks!

Never got any issue recently after updating v 18 ROM I am having issues like app crashing but not lagging or hanging ..

Officially, SDS doesn't exist. Samsung just doesn't want to acknowledge the problem.
[Galaxy Note II Q&A, Help & Troubleshooting] joseaugusto1:
May I know where you got your phone repaired? mine died a week ago...
[Galaxy Note II Q&A, Help & Troubleshooting] Bright.Light:
It didn't cost me anything - still under warranty. And, if the warranty was out, I would be complaining so much in the store that they just had to give it to me :P

This is a mailfunction of the device, there is not anything that I can do to prevent it. This means it is a well known mailfunction from the factory, meaning an extended warranty under European law.

I bought the device with Alternate in Barendrecht (The Netherlands) and they had to mail the phone to Samsung repair, I believe somewhere in Limburg.

What you notice has nothing to do with SDS. When SDS, the device won't boot, won't even try to boot.

Have you tried all those other possibilities, like booting to download mode, or to CWM/TWRP?
[Galaxy Note II Q&A, Help & Troubleshooting] Fokas.:
I spoke to soon. It doesn't freeze still, but now is unable to make calls or use data in any way.
[Galaxy Note II Q&A, Help & Troubleshooting] azki21:
Hey all I recently lost my Note 2 to SDS I bought it not long after release and died almost 200 days later while charging. I sent it in as it was under warranty with a description of SDS and entailing what needed to be done to fix the issue. It took almost a month but after accusing me for damaging the phone (the phone was physically in mint cond.) And saying the phone was unrepairable because of miss treatment it was sent to Samsung afaik. Which gave me no problems they actually replaced the phone with a new one instead of switching motherboards. I had to wait a few days extra as the nearest Samsung shop had run put of stock for note 2s but I got a new one. Now with my last phone using emmc brick bug check it said the dreaded " Insane chip " aswel as the 0xf7 revision. This phone has the " Sane chip " but still the 0fx7 revision. Im worried because it says the revision is all that matters. Not the chip. I called up a Samsung technician and asked about SDS I was put on to a guy that's repaired several SDS S3s aswel as Note 2s he told me the insane chip is considered faulty and explained the writing to memory and complete death of the chip for possibly several reasons but said he couldn't pinpoint a specific cause. I told him about my phone and the emmc chip being the Sane chip instead and he said i will be fine as so far every SDS he has delt wit h was devices with the Insane chip and he replaces boards with the sane chip as a fix even though the revision is the same and assured me I should be fine.

However because of what I've read on XDa I don't believe that and im dead worried yeah my phones chip isn't the insane chip but the same revision so I'm asking will my replacement phone suffer SDS? Its non rooted and only a week old fresh stock too but still I worry 0xf7 revision ):but not the insane chip. .. should i be worried ??
[Galaxy Note II Q&A, Help & Troubleshooting] .NetRolller 3D:
AFAIK the insane chip is rev. 0xF1, not 0xF7. The bug checker uses this to determine if the chip is sane or not. So, you shouldn't see a 0xF7 chip showing Insane.
[Galaxy Note II Q&A, Help & Troubleshooting] Optimistic Pessimist:
Does that apply to N7105 with the Type: MAG4FB
[Galaxy Note II Q&A, Help & Troubleshooting] Itseden123:
Is N7100 4.1.2 SDS protected?and can SDS pop out of nowhere or it happens only to rooted device or ones with custom rom?

Edit: my chip is 0xf7 and it says i have the sane chip,so i'm fine right?
[Galaxy Note II Q&A, Help & Troubleshooting] Colinn789:
Yes, you're safe!

Hello i have the insane chip. Started to have some lags and freezes one month ago. I decided to reset phone but still had problems. Now is 3 days since i dont have this problems. Anyone has an idea if there is some kind of application or setting that could be cause problems or i have a damaged phone and is just a case that is not freezing?
[Galaxy Note II Q&A, Help & Troubleshooting] Colinn789:
Just install the eMMC checker from Play and check if you have an insane chip...if you don't maybe it's just an app. But if you have an insane chip that's probably the cause...
[Galaxy Note II Q&A, Help & Troubleshooting] Docci77:
I checked and i am sure i have the insane chip. Now the question is....why is three days since i dont have freezes and lags? Just luck?
[Galaxy Note II Q&A, Help & Troubleshooting] Colinn789:
yep... I would say just "luck" (if you can call it that)! If the problem started already it means your memory blocks are being "destroyed" and that is not a thing that will fix itself or it will get better, sorry...

Just check this blog and I think you will understand better how the problem works... http://www.roytanck.com/2013/06/04/note-2-update-sudden-death-syndrome/

My dual SIm Note2 just died on me

Hi all, my Dual SIm GT-N7102 just died on me can't power on or do recovery.....whats my next course of action?
[Galaxy Note II Q&A, Help & Troubleshooting] bravomike67:
SDS seemed to have been solved.

Had never heard of the sds phenomenon on note 2 until it started to happen in mine. I had just changed to a flip cover when I noticed my gt-n7100 freeze for the first time since I got it in October 2012. I quickly forced it off and restarted as I wasnt in d mood not to have my only smart fone working fine. It repeated 2x more and by the time I got to this forum, i was losing hope. I downloaded the eMMC checker and after rooting my fone, saw the dreaded fx01 REV from the VTU00M type called the insane chip.

I downloaded and installed the Dummy File Generator app and ran it a couple of times but the problem didnt go away immediately. However, since yesterday, I am pleased to report that the sudden deaths have ceased as I havent had even a single one for about 36hours now.

Whether its an after effect of the fix or its just a bug working out its time, I want to appreciate the guys here who put this little discussion together to enlighten us lay folks.

Spotify prevents sudden death.

I have the problem of Sudden Death with my Note 2: it dies with seconds when it is not in use (idle). A strange solution I happen to hit upon is leaving Spotify in play mode--muted of course. Just for info: music offline data of my Spotify are stored on an exteral sd-card.

Got my Note 2 back from Samsung

After two long weeks I received my Note 2 back from Samsung...it says: "Software Update"

Two weeks for Software Update...these guys must be kidding me...

My phone is for sale now, going back to iPhone, their technical support is light-years away from Samsung. If I pay 600 euros for a phone, it will never be for a Samsung again!
[Galaxy Note II Q&A, Help & Troubleshooting] Docci77:
That is a problem! I think i have the SDS issue but so far i am not having troubles in more then a week...so if i claim for warranty and samsung says my phone is ok i will waste 2 weeks without phone..
[Galaxy Note II Q&A, Help & Troubleshooting] Colinn789:
Exactly!

Let me just tell you a (real) story...I had an iPhone 4 32Gb and the microphone and speaker stop working. As it was under warranty I complain via internet and the next day a courier from UPS came with its own package prepare to take my iPhone and the very next day I had delivered a new iPhone. The best was that my warranty was extended another year!

By the end of the extra warranty year, I did the same complaining about the battery life and again just ONE day without phone and the battery was replaced...and didn't have to go to any store and wait in any line...

I really liked my Note 2 but I also really value the after-sell service and if you pay for 600 euros for a plastic phone with faulty chip and on top of that you got a ****ty after-sell service, so what's the point? For that Samsung could sell it for half and still got huge profit...

Whatever...just leaving my (frustrated) testimonial!
[Galaxy Note II Q&A, Help & Troubleshooting] estugarda:
If it really is sds, than it will get worse and die soon. There is a way to speed that up; use the memory chip as much as possible. Copy. Paste. Delete. Use memory error checks. The eMMC checking app from the market (the one that has Sane/Insane chip check) also has memory check. Run it for few times and see what happens. You're not voiding the warranty for using the phone a lot. And it might speed up the SDS if you got it.
[Galaxy Note II Q&A, Help & Troubleshooting] Docci77:
I read that next month note 2 will be updated to 4.3...will upgrade kernel too? Maybe will solve the issue
[Galaxy Note II Q&A, Help & Troubleshooting] estugarda:
We heard thah song long time ago. They also announced the 4.2.2. for May, and we know how that turned out.

If if they do update the kernel, they will not admit the sds, if they didn't until now. So we will never really know.

Either way, if the emmc is already damaged, new kernel won't help.

Anyone here got your Note 2 died again after replacing mainboard ?
[Galaxy Note II Q&A, Help & Troubleshooting] njfpolyr6:
mine was dead on monday, September 23, 2013. I called samsung mobile USA next day, and they asked me to send back to them to fix it. The rep was very nice, and hopefully i will get my phone back soon. Mine is T-mobile Samsung Galaxy note 2.
[Galaxy Note II Q&A, Help & Troubleshooting] dvn2008:
My Galaxy Note 2 died last month, same symptoms as SDS. I took it to Samsung Service Center but they rejected as the IMEI shows it's not intended for sale in my country. It did not occur to me when I bought the phone that it is a parallel import ones. So I took the phone back to the store and ask them for repair and told them about SDS. After arguing a lot they accepted the phone, but now it has been three weeks still no news about the phone repair.

Any advice what should I do next?

The phone seemed to be from Europe because on the box there are many two letters country code (AT, MT, DE, GB, etc) and there is a sticker "Samsung SmartCare 24 months warranty" whereas Samsung told me the warranty for my country is only 12 months.

I am very disappointed, Samsung should do a mass recall of this faulty product.
[Galaxy Note II Q&A, Help & Troubleshooting] estugarda:
That will never happen. They don't even acknowledge the problem.

The point is, not all note2 devices with bad revision chip will die within warranty period. I'm using mine for 10 months now, and it still runs just fine...They know that, and will not acknowledge the problem before the warranty period on most devices has passed...

The moment Asus Fonepad Note fhd6 becomes available, i'm getting it. I'm not putting up with Samsung BS anymore. Hopefully Note2 survives until then.

As a understand the part of kernel code which "fixed" the SDS (actually preventing certain accesses) not every insane chip is really insane.

Only 0xF1 chips of a certain production date are affected.

The fixing code had been discussed in a parallel S3/N2 thread.

mine too but that doesn't mean anything. in android reboots and freezes are quite common. i remember my old galaxy ace what reboots every day or so and freezes constantly...

if your are safe thats all, maybe try to make a full wipe and it will work better (i do it like every 3 months or so and there's a difference)
[Galaxy Note II Q&A, Help & Troubleshooting] sms2000:
I'm pretty sure the most of stability problems of S3/N2 is in their poorly developed power manager.

To stabilize mine at maximum I have to raise voltages all over the list of clocks. My 200MHz voltage is the same as 1300MHz. WiFi and BT is stable more or less, GPS less so...

Reboots, locks etc. are common when the hardware pushed too much.
[Galaxy Note II Q&A, Help & Troubleshooting] lee yun khong:
Freezes and random reboot was the sds signal for sure.

My phone come with 4.12 when I bought it and also flash secure / fixed patch kernel.

But sds still happened.

My phone binary count was 1, samsung refuse to change chip with foc.

I paid usd 200 and fixed within 3 hours and ready for collection.

And now my phone was sane chips f7.

i was thinking to buy a new note 2 on sale, could it still be affected from this problem?

if it has that chip on board but latest firmware can i have trouble?
[Galaxy Note II Q&A, Help & Troubleshooting] xlost:
A solution, maybe.

I solved the issue by installing Wake Lock - PowerManager by darken and setting it to PARTIAL_WAKE_LOCK. The app also has an auto-start option. Surprisingly, battery drain is bearable. Never had SDS since. Give it a try, and if it works, maybe you could also buy the donate version of the same app.

Interestingly I have a 32G N2. over the last 2-3 weeks it has died on me. from random freezes. Middle of use to have to hard reboot.

I tried re flashing with the latest wanamlite rom... and I can get to the type your google account name details and then it just gets stuck. sometimes the screen is viewable other times it locks hard .

not sure if its the same issue as these ...
[Galaxy Note II Q&A, Help & Troubleshooting] Colinn789:
Yes it could be affected...and if it is the 16GB model there's still no firmware that fix that. There are some software that delay but sooner or later the problem comes back.

Hi,

My Note 2 was also "FwRev: 0xf1". Main problem was not freezes but lost internal memory. After reset everything looked good for a few weeks. Then internal memory started to shrink. And finally I get error about no internal memory. After two resets I went to Samsung technical centre. It was yesterday. Today I got my Note 2 back. They changed mainboard and something more. Now I got "eMMC chip Type:V3WM, FwRev: 0x00". So it seems that not in every country Samsung is stupid :).
