[Q] SGH-T989 (T-Mobile Galaxy S II) Issue, not sure if bricked.

Hello! I am new to XDA Developers. I have been reading for ages now, but i had never created an account until now.
I have fully searched this issue with my Galaxy S II and i can't find any answers.
First i will describe what my phone is running.
Jedi Mind Trick V9
Faux Kernel 012
pretty much Jedi Mind Trick Stock, no custom kernel or radio etc.
Second i will describe the situation.
I was making a phone call when suddenly the phone cut off, then i went to look at the screen and all the screen would do when i pressed the power button was flicker in a screen with rainbow colors, (my video will explain visually what this is).
I have tried everything from a hard reset to recovery mode and so far i cant find any answers.
I also opened the phone and swapped the LCD display with an exact model and the same thing happened on the other LCD screen which leads me to believe either something fried on the motherboard or something software-wise crapped out.
The phone has not been dropped recently or mistreated, just used normally with a few wear and tear.
Please i hope someone can help me, as i have no way of getting another phone for the moment.
(apparently i can't post videos yet but if you send me a message i will send you the YouTube link)

Warranty to samsung or T-Mobile

It for sure seems like internal or software issues. If you can't flash a ROM then your most likely bricked. You could use ODIN as a last-ditch effort to get your phone to work. Good luck!!

[Q] Note 2 won't Turn On WiFi or Bluetooth Settings

I tried toggling it on after the 4.1.2 update, but it won't let me the upgrade was done through OTA and carrier is Fido. Same thing with Bluetooth. It just toggles back to off on it's own.
Any help or suggestions? I'm thinking of restoring it to factory. I'm enquiring for my mom's boyfriend. He does have SuperSU installed but I don't think it's rooted because I'm pretty sure he won't know how to do that. Could this be causing the program?
He's thinking about going back to the iPhone which in my opinion would be a huge mistake after witnessing the note 2 for power myself haha.
Just tried doing a Factory Reset to no avail. Still toggling from on (for a brief second) back to off.

Yeah that was going to be my next step, but then downloading the Firmware is going to take forever. I am thinking about flashing a Custom ROM so it will remove the bloatware with it. I'll update the thread when I get a chance.
EDIT: I was so smart yesterday that I flashed Stock Restore by accident and now I have to use someone's computer to flash CWM back into it or Unroot the phone...It was such a dumb mistake.........

Very well known to me issue...
1. Never attempt to undervolt Note 2, especially on low clocks. Don't play with RedPill kernel. Use stock, Adam or Perseus.
2. Flash stock 4.1.2
3. Shutdown, remove SIM, battery and SD card.
4. Press and hold the Power button for 30+ seconds (I used a full minute).
5. Insert the battery only, power on and try to enable BT and WiFi.
6. If succeeded - shutdown, insert SIM & SD, reassembly and power on. Verify again.
If not... you may try again or go to servicemen.
7. Later you can flash a custom ROM but beware of kernels and especially undervolt.
P.S. My old trusty Motorola Atrix doesn't like undervolt too. It looses BT...

Thanks man. It is super weird though because I don't think he had it rooted and I checked the Kernel that he had installed it showed it was the stock kernel. I will keep that in mine. I was also wondering and this maybe a newbie question. But n7100 can only flash stock n7100 4.1.2? I just find downloading the firmware will take forever.
Thanks for all your help guys. Will jeep you both updated.

Any update?
My t889 have the exact same problem. Wifi and bluetooth won't switch on.

my galaxy note 2 does the same thing
I just purchased it and went to turn on wi fi to download apps quicker and it goes to on for a second....then just goes off. Same with bluetooth option.

wifi can't turn on as well as bluetooth
hello,
has anyone solved this problem? just came back form work today and try to turn on wifi but failed to do so. Please help...thanks in advance.

Thanks man
Thanks man

Same Problem with WIfi and Bluetooth
I experienced the Same issue sometimes when i removed my battery i can turn on my WiFi and Bluetooth but after a couple of days the Wifi and Bluetooth can't turn on again. Anyone already fixed this issue?

The back cover serves as the Wifi antenna. When you open the back lid, the two gold prongs on the upper right are the connections to the back cover (antenna). Make sure the contacts are clean and the back lid is attached completely. When insufficient contact is established, wifi will not turn on.

This is NFS antenna. Seems having nothing to do with GHz range internal antennas.
Anyway will do no harm to have it properly attached.

Won't fix it as I've used both Jedi Master and Jedi X ROMs before reverting to rooted stock (which I'm still using) and the issue persists.I think this is a hardware issue.

Same problem over here
My problem has been on going since I bought thee damn thing
I bought it from someone for $500 back in April. The guy I bought it from must have been some sort of genius or something because every freaking repair place and computer places, in Tulsa, OK, have absolutely no idea what the guy that I bought it from did! I remember it had a custom ROM I think it was Jedix..sorry I am a noob and a girl at that :/
I have spent countless hours reading forum after forum to no avail.
So the guy that I bought it from asked me if I wanted regular 3g/4g speeds and wifi or fast internet speeds everywhere and no wifi. I, assuming that I could easily just turn wifi back on with the flip on the button, told him that I wanted fast internet and no wifi. I get home and try to flip wifi back on and nothing! Also no bluetooth. I was in contact with the guy that I bought it from and he did try to walk me through turning the wifi/bluetooth back on. He said it was simple..He had me wipe the cache, wipe the kernel, something to do with qual comm settings..blah blah I do not remember because it was months ago and so many things have been done to it since then. I shortly lost contact with him. If I am within 2 feet away from my router I can pick up great wifi but 3 feet away or further I am s.o.l. I can pick up a real weak connection in public places like my college or a hospital. I have paid every phone repair place and computer store here in Tulsa to try to fix it. They all do the same thing, just restore it with the exception of the last place that I took it to..they tried to but an older version on it thinking wifi/bluetooth had something to do with version it was on.
Please do not tell me that this is a hardware issue!- I have read countless forums and have read that I am not alone with this issue. It does however not look promising because I have never read of anyone fixing this issue. I have read things about it being the radio etc etc. I firmly believe that this is a software/programming issue however the people that I have seen this happen to never got it fixed..they eventually just gave up and bought new motherboards or new phones entirely. With that being said a motherboard could be a possibility..any ideas on how much a new motherboard cost? Sorry for being sooo long I am just so frustrated. This is such a beautiful phone and I have never gotten to fully take advantage of all of its capabilities because of this.

WIFI Bluetooth fix
Hello, I´ve also tried everything software related to no avail. So I finally disassembled the device as shown in videos found on youtube or elsewhere.
Google it!!
Reconnected the wifi chip. Turned the the device on and....wifi and bluetooth worked strongly!!! That fixed it for me!!
To be clear: I just took the screws and the plastic piece that covers the motherboard (Bee careful and patient and use the right tools!!). Then disconnected and reconnected the connector of the wifi chip, which is located right next to the lower volume button, on the board. It´s the only cable showing.
I´ve seen this problem on laptops, because of overheatin issues related to bad mainboard design, but I cannot be sure in this case without further testing.
I´ll see how long this fix lasts and I´ll keep posting.

It worked for a day and now it´s back to the same....To my understanding this is a hardware problem with the wifi/bluetooh chip.. I´m looking for the brand and model of the chip to see if I find it on Amazon so I can replace it.

[Q] my galaxy note 2 wont start (urgent please help)

Dear all,
I am in deep trouble , my phone was working fine yesterday night but some how today in the morning when I was trying to switch it on the phone wont respond no startup logo nothing I tried to remove the battery/ sim/ memory card but still nothing happening I tried to plug the phone to laptop but it is not responding even I connected my phone with the charger no signs is it really charging or not, but still I tried to charge the phone for atleast 7-8 hours , only thing which I am getting is the red identification light keeps blinking when I try to switch on the phone , otherwise phone seems to be completely dead.
I am rooted & I have jelly bean 4.1.1, any help in this regard will be appreciated ... because I already have void the warranty by rooting although I have set the binary counter to zero through triangle away app.
thank you very much.

I think that your phone have SDS. But in your case i would check battery and charger - if that wont help just send it to warranty (if this is SDS its hard to check that you have root

I must say you should flash ur note2

thanks for the reply, I have tried 3-4 different chargers but no work for my phone for battery I have to check it, I heard that same crazy stuff were happening with SG-S3 but I is not the case with note 2, SDS means they have to replace some hardware components will it going to effect my data in phone also.
thanks again.

Dear member, thanks for the advise but it is not possible as my phone is not detectable by PC, so flashing is not possible until you tell me some other way.

If download mode not work in my opinion there is no way to bring it to life at home. Only replace motherboard can help.
Yes the same bug is in SGS3 (same eMMC chip on board). This is happening on 16 GB variant of sgs3 and note2. To avoid this next time use android 4.1.2 (Samsung propably fix this, - risk of SDS on newest roms are lower).
Try to check voltage on battery.

Have you ever flashed it before.. if not then you can claim warranty
If you have flashed it once or more the counter will raise and samsung might be a b*tch about it and charge you for it (like they did with me)
The thing you should not do at all if its the SDS is flash it because it will not write NAND and will always fail then

Guys just today I have seen this thread...
http://forum.xda-developers.com/showthread.php?t=2093599
SDS chances are high on my device also, as the symptoms seems to be the same for me, I didn`t have the chance to check my phone chip but I did buy the phone on 20th Oct 2012, so fingers cross, I will recommend to go through the above thread, to safe yourself from any unpredictable hassle.
Wish me a best of luck, I will going to visit service center today.

Good luck :angel:

Hi guys,
The update is my mother board was effected & replaced also, I lost all my data from sd card, board is replaced by service center at their cost as it was in the warranty so luckyly rooting my device did not make any issue, they have installed the latest firmware jelly bean 4.1.2 which they told me will make sure not to happen again

[Q] How to flash empty logic board?

Hi to everyone!
Well first at all sorry for my lame english, I don't usually use this language for posting, and also I'm new to posting things, generally I read all post but in this case I don't find anyone that could help me this time, and there's my case explanation:
Well, a few weeks ago (a month or so...) I was repairing a SGNote II N7100, the main problem is that it was submerged in a pool by her owner for 30 min. and then (when the owner was aware that he weared it, but anyway) he hung out to dry, after a couple of days he tested it again and detected two main problems:
The SIM Card readere wasn't working out properly, won't detect any SIM Card putted on it,
When the Note goes through deep sleep it dies, doesn't wake up anymore, so you need to remove the battery and turn it on again.
So for the repairing I buy a brand new logic board hoping for it came with a working OS but It doesn't have one, after a wait of 3 weeks (and yes from asia, it's a pain their delivery services), came totally empty, and when I say empty it's that totally EMPTY, I just turn on the phone but nothing goes beyond of the boot screen, I can't go though the factory recovery, but actually I can go to Download mode, a little ray of hope keeps me fighting on, and using ODIN for keep on, the things tha I'm trying now are:
First: Find a working LATAM stock ROM, (Telcel, Movistar, Claro, or any company on LATAM)
Second: IDK if I must find phone, csc, and bootloader for flashing.
Third: I need to find a working PIT for the rom that could help me, the logic board have 16gb and also IDK if it's a defective sudden death chip.
So please, please!! could you community of XDA help me for repair this phone from zero?
I have the new logic board, and the dried out logic board, I think that the dried out could help me for EFS backup and load that backup on the new empty board.... so I'm yours and thanks for help me

[Q] Bricked Note 2

I've been having power issues with my AT&T Note 2 (draining battery when completely off, wouldn't start after changing batteries without first plugging into USB). I swapped the USB charging port with no luck. Reverted to old backup I took which didn't solve the problem either. And lastly, I started to wipe it and revert to a factory image. Aftering wiping data, system, cache, etc. my phone is stuck on the battery logo screen (no animation). It won't boot into download or recovery. I tried a homemade jig which isn't working.
I have about a year left on contract. It was refurbished and has no warranty left. I have a couple questions:
1. Should I try a jig from amazon? I'm not seeing any specifically stating they'll work with the Note 2.
2. If I've hosed bootloader or have a hardware issue, what's the chance a new mainboard will fix it? (is the internal memory part of the mainboard?)
3. Should I see if I can find a repair shop that will use jtag or something similar to salvage it?
4. Do I sell it for parts (hoping I'd get ~$200 since the display and glass are in good condition) and buy a nexus 5?
5. Any other suggestions?

There is hope, you can take the shoot.bin from the update and put it in a tar file with the files from the old stock tar and flash it. I had the same problem and did this for the sprint version and completely downgraded, boot loader and all. You can find the info on the sprint version. You can email me at keithgordon66 @gmail.com and I'll give you my number so you can call me and I can talk you through it, its easy.

I was finally able to get it into download mode by removing the battery, plugging it into my laptop via USB, and doing the normal 3 button combo. Flashed the stock ROM with these instructions: http://forum.xda-developers.com/showthread.php?t=2275844 (what I was trying to do when it apparently died on me).
