[Q] My T989 wont turn on

Never seen or heard about anything like this. I wonder if anyone encountered a similar situation.
I have a good reason to believe my phone is not bricked, although I'm not sure which is worse.
I'm not sure if it's related, but it might be worth mentioning here:
I noticed, since I started using this phone, that the battery level sometimes drops very fast. Normally the phone maintains normal battery level, but while opening "heavy" applications (e.g waze, google earth) or even during a phone call, It drains the battery out rapidly, roughly about one percent per two minutes. Sometimes even while connected to charger the phone shows a slight decrease in battery level. And it gets hot too.
Few hours ago, I turned it off to save some battery for afterwards, and since that moment it wont turn on. I tried several things.
I left it to charge.
I took the battery out and placed it back after a while.
I tried all possible combinations of the three physical buttons on the device.
I took out the sim card and the sd card.
At home I checked the battery, It shows normal voltage of 4.1V. I used several usb cables and measured the voltage between the battery connector inside the phone while the battery is removed. It indicates that the phone keeps charging the battery even while staying in this situation.
While plugging it to the computer, the phone is not even identified by it. It wont react to the computer just as if it's not connected at all.
Getting it to usb mode showed no result.
I have installed new roms on the device several times, yet more than a week has passed since the last time, and the phone worked fine since. except for the battery issue that I mentioned.
It was originally bought from T-mobile without contract, and it has a warranty assuming I would be able to bring it back to stock rom. Anyway, I'm using this phone in Israel and the nearest T-mobile service point is 10,000Km away, so I would do this as a last resort.
Hope for some advice, and may this post be able to help others that got in to similar situation.

Have you tried getting it into download mode? Disconnect from the PC, then keep both volume buttons + power button pressed while connecting the USB cable to the PC.

Phone won't turn on
Just had this same experience. I had just taken mine off the charger in the morning, booted it up and minutes later, it restarted on its own. Never came back to life. No possible combination of buttons, batteries, usb cables, ODIN running/not running would bring my phone to life. I mean I tried everything including the famous usb jig. Nothing. Sent it in to TMo and as it was within 30 days, they sent a new one which is running fine.

The problem is...
The phone is not recognized by any device, while being connected to usb. The only thing it does while plugged is to charge the battery, and that I can tell by measuring the voltage. It gives no visual indication, or respond to any button\connected device. Using that jig is the only thing I got left to do. I know it suppose to reset the counter. What else will it restart? My rom?, internal sd? the recovery partition? Can this physically damage the components on the phone's PCB?
And assuming the phone hardware is unharmed, are there any firmware malfunctions which are impossible to repair? (Generally I know there are, yet I'm asking specifically for these phones that comes with "download mode")

Had a situation where the device wouldn't turn on. Woke up one morning and it was still on the charger yet totally unresponsive.
Pulled the battery, waited 30 seconds and everything was fine.

I wish it was that way for me too, yet it was one of the first things I tried. and yet, Nada. Here are some news: I gave the jig a try, and it didn't seem to work either.
On contrary to most of the fully bricked cases I heard about, my phone wont be recognized by the pc at all while being connected to usb. Not even a "Faild to connect" message. That leads me to believe that it is either a dead Boot-loader or a hardware malfunction.
I made a little research, and found out that it is possible to connect the pc through some kind of adapter directly to phone's processor, using specific pins. It is a simple kind of serial connection called Jtag. Initial factory configuration of electronic devices is only one application of it.
For that process I need to have that device along with it's driver, a boot loader to flash (According to what I've seen the T989 is not yet supported by these softwares).
I need to have some nerves to open up my device and to solder some pins (And I also need that Jtag pinout).
Does anyone know about a better way of doing it other than sending the phone half world to the U.S?

Possibly bricked E4GT. Advice please.

Hi all,
For the last two to three months, I've been running a Universe ROM on my E4GT. Other than an occasional quirk, the phone has been working very well. I noticed that my phone didn't seem to be connecting to my home WiFi, so I put it into Airplane mode, and then took it out of Airplane mode. Instantly, it connected to my WiFi with a MUCH better signal After checking emails on the phone, I set an alarm and went to sleep. I woke up without the alarm since it did not go off. My phone appeared to be off. Holding the power button resulted in the blue LED charge light flashing, but the screen did not come on. I pulled the battery and put it back, thinking that the phone had some odd-ball software glitch that made it turn off in the middle of the night. When I hit power, the blue LED turns on, blinks, and that is all that happens. Once and only once since this started, my screen showed the boot animation, but did not get past that.
Because my screen turned on ONCE, I'm really hoping that I am soft bricked and not hard bricked. It does seem VERY odd for the phone to become bricked after working fine on this ROM for at least a couple months. The only change I made in recent time is to change a governor in ExTweaks from Hyper to Ondemand. I suppose that could have somehow caused this.
I stopped by a Sprint store, but they would not help as I do not have insurance and the phone is out of warranty.
Do you think making a USB jig or buying one may help? There is a Radio Shack close to where I live. And I have an extra USB cable I can take apart.
If that fails, should I send the phone to mobiletechvideos.com for their JTAG repair? It costs $50 plus shipping to them, but that is still cheaper than buying a new phone. If it came to that, I'd certainly hope they could fix it.
The fact that the blue LED light comes on seems like a decent sign of some life. While the battery animation does not come on, the light does.
Thanks for reading and offering any advice/suggestions.

Can you get into recovery or odin mode?

Nope. When I try either, I get the blue LED light, it blinks once, and then stays on. Nothing happens on-screen.

Charge your battery. Use an external charger if need be.

I thought that it could be the battery. My original got bloated about a month or two ago, so I bought an Anker battery from Amazon. It's been working great since I got it.
I had my Anker battery tested yesterday at a "Batteries Plus" store. The clerk put a new battery in the phone to see if it would help the phone, but it did the same blue LED thing. He used a multimeter to test my battery and the new one the store was selling. He said mine had more power in it than the one on the shelf and indicated that either battery has more than enough power to start the phone. While this still could be caused by my battery, it does seem strange for a new battery that has charge in it to not allow the phone to start. I don't have an external charger, but I could always visit my parents as they each have an E4GT.

Just went thru that and you have the same EXACT symptoms as my emmc brick. Jtag will not help so don't waste the money. Plenty to read on the emmc bug in the E4GT and SGS2 forums.
I hate to be a downer but, I can guarantee you that you will not get any more than the dreaded blue light no matter what you do.
Take it to Sprint and let them go thru the entire process of trying to get it to boot and they may even give you some kind of excuse like "well I'm gonna take it to the back and disassemble it and see if the screen connection came loose".
They will never get it to boot and it is a hardware problem!!
Free replacement and may be backordered because this problem is happening to quite a few of the first run Galaxies.
I spent hours on the phone with "supposed techs" and went to 2 stores because my home store "child" said I must have gotten it wet and handed me a card with Asurion and said to contact them and I'd have to pay my deductible. BS, i wasn't paying for a hardware issue and YOU NEED TO TELL THEM THAT!!!
I spent a week and a half checking components (after they had taken it apart already at the store) while I waited on my replacement because I wanted what was on my internal memory and nothing. I know enough about electronic repair doing it my entire life since I was 12, that you will not get it back.
Sorry but like I'd said "i just went thru this 2 months ago" and plenty to read here on that situation.
They won't see any mod or even any display so you're safe with the Sprint techs. Just tell them when you woke up after setting your alarm, it was dead.
One good thing, is your replacement should be pretty safe from the emmc problem and download Chainfires app to see what chipset you get. (GotBrickBug)!!
I will say that everything was working fantastic on the Rom I was using and it wasnt due to a botched flash. I was taking a couple pictures and when I plugged it into my laptop, I'd noticed it must have shut down never to boot again. It could happen at anytime I'm noticing.

Thank you very much for the reply. My phone was having a strange issue with connecting to my home WiFi before I put it on the charger for the last time. I wonder if that was a tell-tale sign that something was up.
I went to the Sprint store closer to where I live and explained what happened. They didn't give me any argument at all. Their tech checked out my phone, but couldn't get it to power up at all. They ordered a replacement E4GT (might be new; might be refurbished) for me for $35. I should have it by Friday. I was surprised by how helpful they were. Apparently, they have see this issue occur on some other Android phones as well.
What is the Chainfires app? Does it identify if you have the "older" chipset which can cause the brick issue? That must be what you mean by "GotBrickBug," right?
Since I'm eligible for an upgrade in June, I think I'll just use the stock ROM to avoid any possible issues. I wonder if the GS4 will be out then. It's always interesting to see what the hot new phone is going to be when you're ready for an upgrade.
Again, thank you to everyone for the helpful replies!

Surprised they even had you pay but I'd have paid $35 also if they'd asked me too.
You should get either new or new board at least.
Here's Chainfire's thread and app in OP. By the looks of it, my chips firmware is updated and as much as I've tested and flashed in the last couple weeks, it's holding up great. http://forum.xda-developers.com/showthread.php?t=1693704
My first clue was that my phone was having problems being read by my PC. Couldn't see either the onboard usb or my external usb. It was intermittent and within a week it was gone.
Sprint has been seeing this problem for sure and in Chainfire's thread, Samsung is well aware.

Sounds like the h/w took a dump on you - the phone replacement was probably the only route left. By any chance did you leave it charging and/or in a location that allowed it to store heat? (Like a blanket, foam cushion, etc)

That's disturbing. I always thought that bug occurred when attempting to reset to defaults in the wrong way. I didn't think it could happen out of the blue.
In my case, which is awfully similar to the OP, my battery was running low, somewhere between 10 and 15%, and since I couldn't charge at the time, I powered down the phone. Next morning, I plugged it in to the usual wall charger and saw the battery charging symbol come up on screen as expected.
Instead of simply waiting for that screen to go off, I hit the power button to turn it off right away, but I might have inadvertently also pressed Vol Up with power or Vol Down with power, since I was doing it casually with one hand.
I didn't notice what might have happened right then, but a little later I saw that there was no charging LED. So I tried all the button combinations I knew to get it to come back to life, with and without the battery and power.
A couple times I got the blue light and then the battery charging screen, before it disappeared. Once I saw, in small print, "Battery low!! Can't Download," which makes me think that it's stuck in ODIN mode, which AFAIK doesn't support charging.
Right now I'm in the midst of looking for another battery or an external charger. I hope this is not what you're talking about.
Update the next day: I found this thread, which is essentially a match for what I was experiencing. That one ended with a wait-it-out approach, and I basically did the same. I left it plugged in overnight, even though it appeared not to be charging at all (stone cold, no red light). In the morning, it was still all but dead, but I popped out the battery again (I had done this many times before), replugged it into power, and then it charged normally and completely for the first time since the incident. Moral: don't let the phone go below 15%, and if you do, plug it in ASAP. Don't ignore it overnight, even if it's powered off (maybe especially).

You're right - folks, this is not the eMMC bug. Let's just clear that up. If you need further information on that you can refer to the discussion thread on that bug and all the research that several folks have put into it.
When I first got my E4GT there was talk of a BLOD or "sleep of death" where the phone would not come back on. Wasn't the eMMC bug. Most people had a low battery so it was thought the batteries were too low and that it booted and messed up the bootloader. Others thought they overheated. Problem is without any way to diagnose the problem it's hard to come up with a "true" answer.
Perhaps a JTAG could revive the phones. Odd that even if plugged in that nothing is happening. But sometimes h/w really can just go south and trash a phone.

I highly suggest backing up your internal usb drive as frequently as possible because I lost a lot of photos that I never transfered, thanks to Samsung and my hardware taking a crap. Emmc blue light bug really sucks, believe me...

Doesn't sound like emmc at all. All you will have is a blue light and that's it. If you saw ANY display, it's probably a battery and charging issue. You'll know the bug when you don't see anything but blue and no display at all.

anindrew, how did it all turn out?

Not charging, screen flickering

I bought a note 10.1 2014 Ed a couple of weeks ago on eBay. Not refurb and sealed in the box.
Devastated to find tonight, after completely discharged and shut down, that it seemed not to charge at all.
It becomes stuck on either the battery symbol, where nothing happens, arrow doesn't spin and no animation, or goes to the device model name. All the while the brightness flickers.
Have tried various chargers, I've taken all the cards out but nothing is working
I think it may be a loose connection with the battery (but open to other theories).
If anyone has had this problem, how have you fixed it? Is it worth disassembling and trying to fix it myself (as I'm sure you can tell I don't have a lot of knowledge about this)? Being an eBay purchase is it still under warranty with Samsung? How much would a fix be if it was a loose battery?
Thanks in advance

As far as I am aware items from ebay are not covered under warrenty.
Even with the screen off and nothing happening, leave it on charge for few hours then unplug and try to put it on.
Also have a look into the charger port of the tablet at the bottom to make sure nothing looks bent or out of the ordinary.

samsung sm-p605 dead not starting
havig the same error mentioned above.. got the device new from amazon, shipped to chile where i live.. recieved it and tried switching on and didnt switch on.. tried connecting wall charger for couple of hours no progress not even battery symbol coming up.. tried usb to laptop battery image comes up with no animation.. and screen flickers... boots in odin mode... when tried booting in recovery mode stucks in screen where the model name appears...
plz help since i have 0 hrs of usage completely new.. chile samsung doesn't accept becos its purchased in usa.. any email of samsung will also help
shame i always liked samsung over apple.. and bought a product with no support.. apple atleast accepts product bought anywhere in the world and even replaced battery for my frnds iphone 5s when in warranty...

I have not had this issue with my Note, but my Nook did the same thing once. I disconnected the battery for a few minutes and everything reset. No idea if this will help, or if you are adventurous enough to try it.
Here are some pictures of the Note tear down. http://forum.xda-developers.com/showthread.php?p=49595697

samsung sm-p605 dead not starting, screen flickers
i am going to try removing the battery as u said.. lets see..
anyother ideas plz let me know..
but shld i do this quite often?? is this an known error of note???.. do we have this problem when complety drained????

samsung sm-p605 dead not starting, screen flickers
no luck.. i removed the battery from the board, then plugged in back after couple of minutes..
still in same state..
the screen flickers a lot.. is that normal when the note is completely drained..???

It is very bad for the battery to go completely down. I don't let it happen on my devices, so I cannot say if the flicker is normal.
My experience with the Nook was actually a friend's device. He had let it run down, and it was not charging. He left it on the charger for a few days, and it was still not showing a charge. He gave it to me to check out. I disconnected and reconnected the battery. It was probably half an hour or so, because I was interrupted. When I reconnected the battery, the Nook popped on and reported a full battery. Apparently it was charging but not registering anything, and the disconnect allowed things to reset.
If you do not any other ideas, I would suggest leaving on the charger overnight (or longer) and trying the disconnect again. Maybe leave it disconnected longer too.

I have the same exact issue right now! But mine is a refurbished unit. I tried the battery unplug, tried leaving it charging overnight, letting it discharge, flashing new roms, new kernels, etc. Nothing. THe only thing that did work a little bit was changing the kernel. Other than that, even flashing stock ODIN roms wasn't working.
When you charge yours, does it charge up to 75% but won't go any further? And does it take an extremely long time to get there? Because mine does. Reading about other devices that have the same issue, it seems to be the battery. But the other devices were phones. This is a tablet. The battery costs $65 :/

I know this is a very late reply and you have probably solved your problem by now, but for future readers with this problem:
I currently have the exact same problem, and just found out what it was. Either my charging cable (official Samsung cable) is faulty. I plugged it into another microUSB cable, and it is now charging again. No more battery symbol that doesn't have the spinning animation or flickering, and now it turns on.

Thanks for this information. Exactly this was the issue. Great!

Charging works and screen stops flickering with Samsung charger if you let it charge in Recovery mode. Mine is still charging as of now, so I don't have any news further yet, but it went from 0% -> 3% after around 30min.
Other than that, I only managed to get charging working with a Motorola's turbo charger.

Help with dead M8. (No forum for m8?)

Hi - i hope its ok i place it here.
So, i got my friends m8 for free, since its completely dead.
This is what he told me.
He started doing system reset thru the pc software, the software or phone crashed and he couldnt start the phone, he started it to recovery and pressed factory reset, the screen went black (screen where on but it was black, nothing on it) and he couldnt do ****. after a while it eventually died from no battery and since then its been in his drawer, this was in dec.
today i got it, put it in the charger, at first it randomly showed that it loaded with yellow light going like yellow like 2 seconds, no light 1 second, yellow light 6 seconds, no light 3 seconds on and on for 2-3 hours completely random, never stable yellow light that its charging.
now its not showing anything at all eventho the charger is in, the phone obv wont start, and best of all when i was at my mate i lost my xperia z3 compact somwhere in swedish town stockholm, we ate at a fancy resturant ant went to alot of places so thats gone.
what can i do? i run a small pc support business so i cant be without phone and having bought 2 new computers today im totally on zero money, no friends or family that has some old crap either.
please give me any advice.

i just put the usb into the computer and on a dead phone not showing its charing and not on and not able to start it, my computer goes "installing drivers qhsusb_bulk". gives me a bit of hope.
btw my friend said the he tried to recover it by the phone, not the pc software, and then the phone hang up

You are so very much opening yourself up to a load of piling on here.
The M8 is a very popular device and has loads of support from a strong base of users. Post your question in their Q&A forum to get help from them.

NOTE7 N930V and N930F Problem with ROM.

Hey.
At the beginning, I would like to apologize for my English language, but I am using a Google translator. I have several pieces of Samsung Galaxy Note7. I'm having two problems.
One copy is the N930V, with software from the American Verizon network. The problem is that there is no software in Polish. In addition, there is a message to return the phone, even though it charges up to 100 percent. Can anyone help me find TWRP to N930V, and find some Custom Rom? I am a layman.
2 copy is N930F.
The phone sometimes turns on, but only under the charger. The battery only charges up to 50%. When the screen goes off and I try to use the phone to wake up from sleep mode, vertical green bars appear on the screen, or enter normal mode, but it immediately shows a message about returning the item to the point of purchase and replacement of the device.
The message starts with the words "Important Note: The Samsung Galaxy Note7 ..."
The software version number: MMB29K.N930FXXU3BPL5,
Unfortunately, the picture is quite rare.
The phone disconnects automatically after disconnecting from the charger. Without a charger, I do not want to start.
When I connect it to a computer with a USB cable, it has not even started correctly once. They are always green bars on the screen.
Can anyone help me with software repairs on these two phones?
