[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?

[Q] GNex will not charge / USB Host not recognised

Hey all
Wonder if anyone can shed any light on what I think is a unique problem - in that I can't find anyone with the exact same issue.
Last weekend I took the SIM card from my GN to place in another phone I was trying out. The GN was powered back on and being used on WIFI as I was doing comparisons, shooting some video of the new phone with it etc.
Popped the GN in a drawer without thinking and left if powered on
(see if you can guess where this is going)
Messed around with the other phone for about 4 days, got my GN out of the drawer and went to put the SIM back in my GN.
1. GN would not turn on initially at all. No recovery, nothing. (solved)
Read some posts on XDA and elsewhere, people with similar issues mentioning a long (5min+) battery pull would wake her up. Dutifully I obliged and the phone did indeed wake up. However, battery was totally dead and phone shut back down.
2. GN will not accept charge from a wall charger when phone is on.
Whilst the phone seems to take a 'trickle' charge whilst powered off (battery charge animation is on), this is exceptionally slow. Took all night to get to about 50% charged to allow me to boot up and have a look around. Whilst the phone is powered on, it will not recharge. tried all sorts of official and other USB and mains cables.
3. When connected to a PC via USB, will accept charge, but error message notes that USB Device not reconised, troubleshoot? etc...
Phone won't mount. Status says it is charging over AC.
So what's up? I assume the battery died big time over the 4 days i left it. A have a new official battery in the post to resolve but... didn't anticipate the issues with USB connection etc. Worried the phone might be partially bricked/borked/knackered.
Phone is GSM 16Gb currently on 4.0.2 and totally stock. So no tinkering to date has caused this. Only event that proceeded the issue was the full battery drain.
Any hints / tips / info / moral support gladly accepted.

Really sounds like you're phone was already borked, just waiting for the right time to tell you. You might've hurt it's feelings.

Sounds like it's emotionally scarred from being abandoned for another phone and left in a cold dark danky drawer for half a week.
Have you tried reinstalling the USB drivers?
Also could try factory reset as well as try unlocking it and relocking. Worst case, send it in repair, just tell them it's heartbroken.

Heartbroken, I like it... Worse still I was testing out a Windows Phone. What a phone philanderer I am.
The drawer was nice and dry though I assure you.
How would I install USB drivers?

Assuming you're on a windows since you called it a PC..
Try and see if windows can install it for you.
Go to Start > Run > Enter "device installation" in the search > select "Change device installation settings" > Select "Install driver software from windows update if it's not found on my device"

Many have seen this type of problems, see http://forum.xda-developers.com/showthread.php?t=1427539
It's a hardware issue, but is fixable if you want to change the USB port yourself

Thanks.
Then post you link to seems to be about 'phantom' charging when no cable is connected. This is the opposite in a way - it won't charge when turned on at all.
New battery arrived today. No change. Device still trickle charges when powered off, but doesn't charge on mains power, and still will not recognise when plugged into an XP or Linux machine.
Gonna try a factory reset and will update.
Let me know of any ideas and or people with the same issue. I'm still of the opinion I haven't seen a thread with this same issue. Would be happy to be corrected.
Cheers

Well, a factory reset did nothing...
Stuck...

If you read the thread, many have had this exact problem, including myself. For me the phantom charging happened a while after it refused to charge.

What the actual ****...
I just tried what can only be described as the 'toothpick trick' : pushing down the connector nub inside the USB port on the phone et voila, now acting as normal.
I can only describe that as a really ****ty example of workmanship from Samsung.
And it would be after I reset the device as well.
Do you think this one's a definite hardware issue / defect? Seems a crazy thing to happen.

I had the same problem and search as I might, I could find no solution and had to send it in for repairs. The good news is, if you send it directly to Samsung (and dont go through your carrier), they were really fast about it and I had my phone back within a week

Lol, I was the one figuring out the toothpick trick I ordered the phone from clove.co.uk the first week it was released, and had this issue haunt me after a few weeks. As I'm in norway, I was not looking forward to sending it in, so tried to fix it myself. I tried "everything", including short circiut some pins in the plug on purpose, but what finally fixed it for me was to buy a OEM USB Charging board on ebay and replace it myself.
I know, really ****ty QA at Samsung.

Not looking forward to sitting and waiting to see if this is a recurring issue.
How much of a job is replacing the board on the phone?
Sent from my Galaxy Nexus using XDA App

Not that hard. The phone is easy to pick apart, and you can just "plug" in the new card with two simple connectors.

Turns out it is a recurring issue.
Is this the sort of thing that would be classed as due a replacement phone?

I am having a very similar issue that I believe is hardware. Sometimes charges, sometimes won't. BUT it will not be recognized through USB on my PC so I can not flash stock images unroot and lock the bootloader back up. Where you completely stock and unrooted before you sent it in to samsung? I have to find some way to get it back to stock so I can get get this fixed...

Yes, I know there are many topics on this, but mine is a little different, and this appears to be the most current thread.
I have a galaxy nexus that I got from Google IO last summer. It has worked great until last week. It stopped taking a charge. When I would plug it in with the same plug I have used for months, it would show the lightning bolt, but not charge. I tried the toothpick thing but no luck and ended up breaking the usb port. So, I bought a replacment usb board off ebay and installed that. Now, when I plug the phone in, still no charge, but my computer does recognize the phone.
Then after the 4.2.2 update, I no longer see the lighting bolt, but it still does not charge. I have been charging the battery at night. I cut off the end of a usb cable and use electrical tape to tape the two stripped wires to the battery. But that only provides an 80% charge and doesnt last the whole day.
1) Not a usb port issue, but might be a motherboard issue?
2) Not a toothpick fix
3) Maybe a software issue?
4) Maybe time to buy the Nexus 4?

[Q] Charging prob -> replace USB -> phone dead

Hi, I have a 7 months old galaxy nexus (international) which has just turned into a paper weight. I was wondering if anyone here any help.
1) Charging problem:
The problem started when, all of a sudden, the phone restarted while being connected to a computer. I smelled burning and the microUSB connector was burning hot when unplugged. The phone still worked at the time but I couldnt charge the battery. After going through 3 different cables with the same problem, I then discovered online that this has been a common issue with the phone and the only fix seemed to be to replace the microUSB port.
I noticed that the battery might have gone dead also since I was not able to charge it. I went to a T-mobile store and tried on a new battery but the phone wouldn't start!
2) Replace USB:
I bought a new microUSB port connected to a mini circuit board (identical to what's in the phone) and replaced it myself. The only thing I might have missed was that this particular (Samsung galaxy nexus instead of verizon) version has the volume rocker connector soldered onto the motherboard and I had to sort of yank it out. Well, I thought, so I'll be without volume adjustments, so what? And since the connector was still in place, I might still have electrical connection after replacing the motherboard.
Tested another time at the T-mobile store, still nothing.
3) Dead phone:
I followed the online instructions and attempted all kinds of sequences involving charging without battery, waiting for 10 seconds, pressing volume buttons while powering on ... you name it. Still nothing.
Going through Samsung wasnt helpful since I dont have a receipt (the phone is 7 months ago based on its serial number) since I bought it second-hand.
Any idea will be greatly appreciated!!!

additional info
The samsung GNex seems to have some unique quirkiness. When I plugged it in now, the screen, for ~10-15 seconds, will show the battery being charged, before going blank again. And this shows up only sporadically. Another quirk is that if I remove the battery and connect that directly to a PC, the computer will make a sound, indicating the connection, then quickly makes another sound indicating disconnection, before making the sound of connection again and it just cycles continuously until I unplug it. During the entire time, the phone never appeared on the computer screen. If I have the battery in, then the PC wouldn't even make a sound.
I also tried adding some slow-curing conductive epoxy at the solder joints that I had to detach when replacing the microUSB circuit board and that didn't do a thing.

Changing the microUSB port isn't hard at all. There's a good guide over on ifixit.com
Also, the screen turning on for 10-15 seconds is normal for when the phone is off and charging.

Thanks for your reply. I too got information from ifixit.com and replaced the microUSB port successfully (with the exception on the tiny circuit board connected to the volume toggle, which was soldered onto the motherboard and I had to detach it). But the problem is that the phone remained dead afterwards. The only other reason I can think of is that my repeated attempts to charge it while the microUSB port was burnt might have burned something else on the motherboard maybe?
Thanks again!

OMAP flash didn't work?
Just tried using the famous OMAP flash method. I first plugged in the phone, without battery, to a computer. As discussed before, the PC would beep intermittently, indicating a device is connected, disconnected, then connected .... Device manager was flipping constantly as well, as if I am plugging the device in and out. I had to act really fast and double click on the device (during that split second when it's showing that the device is connected) named OMAP 4460. Once the separate window is open, I then click "change driver" and point to the downloaded file.
While I managed to get that part completed, I was unable to proceed from that point. Nothing else seems to have changed. What doesnt make sense is me still is how that should even matter since the problem started with a hardware failure, and why a software change would make any difference.
Any input will be greatly appreciated!

[Q] Charging problem, tried the following...

Ok so a little of background story, if you don't care about it just skip to the next paragraph. I bought my T989 over the internet, it was working perfectly. I wanted to make the most of it, rooted it and tried Swapper 2, which hard bricked my phone. I'm not new to rooting, I've rooted some phones now, but I had never tried swapper, I liked the idea of unoccuping some RAM memory. Apparently I did something to my boot sequence thing and my phone was dead. I still had waranty on the phone (one week left when that happened so it is suspicious to anyone) so I called. After one hour of arguing over the phone and trying to convince them it wasn't my fault, which of course I knew it was, they decided to send me a new one... ahem "new" one.
Ok so here's where the priblem start. My "new" phone was working alright untill it stopped charging, didn't work AT ALL. I took a peek and one of the pins on my phone was bent, it was upwarda and as I tried to get it back to its place it fell off. I took my phone to get the MicroUSB replaced andsure enough they did.
My phone was charging again correctly. It was doing great untill it stated to charge slower and slower. It got to the point where it just shows as charging, but doesn't charge at all.
I've tried everything, I bought a new original Samsung battery, still same issue. I downloaded an app to tell me the amps the cellphone was pulling and it shows 350-450 when I have read it needs minimum 600. I have tried custom roms, kernels and nope, still pulling 400, tried LG chargers, Motorola chargers, a SAMSUNG S3 charger and still no luck. The thing they all have in common is that they're USB chargers so I read if the cellphone detects it as such it would give me a hard time.I've tried making a fast charge USB cable with a video on Youtube but it still only charges 400 mAmps. I've installed custom kernels with the "USB fast charge" and STILL no luck.
The ONLY thing I haven't tried is using and ORIGINAL, Samsung wall charger but at this point, I think it won't fix my problem because of the fact that I remember it worked well in the beggining. I am currently charging both batteries with a Universal Battery charger, but I've read that they wear out batteries throughout time.
So, is there another thing I haven't tried... or is my cellphone doomed now? I believe that it's the phone, as in the mother board if I can call it that, or does anybody have another theory?
Thanks for your time, would love to see anyone suggest

I know this isn't an answer but a general comment. This is a good reason why I will NEVER buy electronics that are used or from a retailer that isn't a big name. I don't care what the seller says there is just really no way to know exactly what you are getting. If you had bought this phone from Amazon (direct) you could have already got another one by now with no arguments. I'd be looking for another phone and call it a loss.

Thanks dude, I know it really matters on where you buy it, but the price was just so handsome to me. I guess that's what I get and as things like this happen you learn more and more on what you buy and what you decide to do with them. I guess I already consider it as a loss but I'm aware that it's not unusable yet. I guess I will continue to charge both my batteries with the charger, but I was just curious to know what really happened to the phone to avoid things like this in the future

What apps do you all have installed on your phone and running while you are charging it? Try making a full backup then do a clean install of your ROM (backup just in case this doesn't fix it). After doing this do NOT install any apps, just test charging. If charging works, it is some app on your phone. I know those "battery saving" apps can eat up a lot of battery if configured wrong. And if you have a lot of background apps running, they can eat your battery without you knowing and reduce charging time.
Go into settings->device and check what is eating up your battery there before charging and during charging.
If you don't want to re-install your ROM, try charging your phone with the screen off (no screensaver (daydream) or nothing, just screen off, charging) and in airplane mode. I recommend doing a clean install to see if it is some apps (you can use TB to back everything up, then do the clean install and test from there).

Can you go into settings->Battery and post a screenshot of it? I'm curious as to what is eating up most of your battery.
After, I would still try doing a nandroid and flash your rom cleanly and install 0 apps and try charging on this clean install. I know my friend ended up getting some battery optimization app installed (which she claims she never installed, but it is on her phone) and her charging times were horrid. It also made the phone quite laggy. I imagine if you got 2 or so of these types of apps on your phone, it could eat your battery instead of charging it.
Also, when you charge it, it is a strict charging cable not a MHL adapter right? I know when I have my MHL cable hooked up to my phone it claims it is charging, but it actually drains the battery slowly. (MHL is micro USB -> HDMI).
Since you have tried multiple chargers and cables, I would be looking at the phone as being the problem. Also, look at the contacts on the bottom of the phone and look for any bent pins. I wouldn't try to fix that yourself, but if they are bent, I'd take it in for repair. those pins are very fragile once bent and can break off if not handled very carefully after they are bent.
If you can get into adb from your phone to PC, then the pins on your phone should be good and the USB cable should be good. Does it charge if you put it in fast charge and plug it into your PC?

The pins are alright. As I stated, I recently changed the MicroUSB port, well I paid somebody to do it and it was working fine at first but then stopped charging, well, not stopped charging actually. At first it started to charge slower and slower untill it got to the point that it just says it's charging but it doesn't charge. It COULD be to the fact that I flashed new ROMs, downloaded games and all but I doubt it since now I have a brand new ROM with no games (or not that many) and you can see from the screenshots I uploaded that nothing's eating my battery
Well except for my screen, I had it at 80% brightness lol. Usually I set the brightness at the lowest (no Auto brightness to save battery) and my wall paper is color black since I heard Samsung phones do save up battery with black since it doesn't light the LEDs or something like that.
And yes, it's strictly USB cable. When I activate "Fast charge" and if I connect the phone to the computer it just shows the notification "USB connected" for a second and then disapears.

The pins are alright. As I stated, I recently changed the MicroUSB port, well I paid somebody to do it and it was working fine at first but then stopped charging, well, not stopped charging actually.

the screenshots attached were helpful. I don't see anything in that list that looks like a huge battery sucker and since you say your rom is fairly fresh and clean, it likely isn't the apps. Are you sure the guy who swapped the microUSB port did it correctly? Improperly soldered pins (especially those tiny ones on a microUSB port) can be tricky to solder correctly if you don't have the correct tips. It could also be that something else got damaged while putting that on (if the capacitors were not properly discharged before replacing the microUSB port, they could have gotten damaged).
I think that your assessment that it is one of the boards (likely the charging circuit) got damaged. I'd go back to the guy who replaced the port and get him to check the charging board (specifically the capacitors) to see if there is any signs of damage or wear. Capacitors can get damaged really easily if the heat on the iron was set too high. I know I've damaged capacitors while soldering things before. Or it could be that the port didn't get a solid solder connection or ended up briding some pins. If fast charge is on, your PC shouldn't see a USB device being plugged in. If you have a multimeter, you could check the resistance on the 4 USB pins and see if any of the pins are bridged.

Well I took it to the guy from before and he couldn't find a problem with the phone's soldering, but even he wasn't sure what the problem was as if it's not his specialty. I do not have a multimeter :/
I was thinking taking it somewhere else and have them change my microUSB port to see if that other person might now a bit more. I'm sorry but I'm more of a software type of person, I clearly have no clue what the problem might be
THANK YOU for really helping me and taking your time to analyze my question, I really appreciate it thanks man
So if what you say is true, do you think it can still be fixed?

It definitly can still be fixed, it'll just be tricky. If they are surface mount capacitors, which they likely are, it is hard to tell when they go.

So what I should tell them to do is to change the capacitors? I can leave the same miniUSB port right?

I would tell them the symptoms and let them tell you what they think should be fixed. In my mind it is likely the capacitors on the charging board that need replacing, but without having the hardware physically in front of me and hooked up to a multimeter, I cannot say for certain. It could be a faulty microUSB port or a bad pin (bridged or microfractured), could be damaged PCB trace, could be gremlins
I would bring it in somewhere or give it to somebody and tell them that the phone doesn't seem to be taking a charge and ask them if they can look at it. If it is still in warranty, send it to Samsung to get fixed. If it is outside of warranty, take it to somebody who knows their stuff (likely a professional repair shop OR somebody who does cell phone or PCB repair for a living... hobbyists may be able to fix it, but to me this sounds like something that somebody with training should likely look at).
Since you have tested different AC adapters (including known-good ones) and different cables (including known good ones) and charged the battery outside of the phone, that narrows the problem down to being something with the phone. You narrowed down it is likely not software related, so that leaves hardware. I know from experience soldering very small components can cause bridges quite easily; even when done by the pros. Some bridges don't matter, but it is better to avoid solder bridges whenever possible. I know I had to replace my nintendo DS slot-1 due to a busted pin and soldering that thing with a large iron was a pain in the behind. Got it all fixed, but it was not an easy task.

This gives me new hope, I really don't mind charging my phone this way, but I'd rather have a complete phone with the ability to charge from a wall outlet
Thanks so much, I hope I can count on you if I run to anything else. And hey, you learn something new every day, ALL of this has been really helpful

Glad I can help. I used to work professionally soldering tiny components before moving into IT. Done some hardware mod to a few cameras, repaired a ps2 controller, have an old tube amp going fix soon too. I've seen a lot of weird things happen with bad solder joints or faulty capacitors.

SM-P607T Charging Issue

I've got a Samsung Galaxy Note 10.1 (2014 edition) SM-P607T tablet. It has not been activated on the T-Mobile network, just used as a WiFi device. Stock Android version 5.1.1. Never been rooted
About a month ago, it stopped charging. It's a couple years old now, and I purchased it factory refurbished (a couple years ago), so I assumed it was the battery. Took it in and they replaced the battery (which was a fiasco in it's own right, but I won't go into that here). But, that did not fix the issue. If I've got the tablet on, it will show that it is charging for about 30 seconds, then the battery shows not charging (either no indicator on the battery or a red "x"). If the tablet is OFF, it seems to be charging just fine.
What I've done:
--Replaced the charging port ribbon--the USB connector was actually broke in one corner, so I thought that was the issue.
--Reset the battery-- a couple of times
--Factory Reset the tablet--a couple of times
--Called Samsung Technical Support. They think it's a software issue, and had me call T-Mobile (since it's a T-Mobile tablet)
--Called T-Mobile. The guy walked me through the power/volume down reboot thing. I get the "Custom ROM install" thing. (Sorry, don't have the exact wording in front of me...) The "this may have been rooted" thing. Which *I* have not done. T-Mobile can't help me anymore.
--Did some more searching and got information to download KEIS. Downloaded it to my Windows 10 laptop, followed the instructions, plug tablet into the USB port and....
-- Get the "the USB device malfunctioned, Windows doesn't recognize" blather. Researched THAT, updated USB drivers on my computer and STILL get the same notice. Powered the computer down, unplugged it, took the battery out, put battery in, plugged it back in, powered up and, still...no go. Still doesn't recognize it.
So, now what? Is there a way "unroot" a tablet without hooking the tablet up to a computer, ie, via MicroSD? I suspect that if I could get it back to an "unrooted" state, I might be able to get T-Mobile's help proper. Any other suggestions as to what to do to get this silly thing running properly again?
I've got someone on another forum saying my battery connector is broke and needs soldering, but it charges fine powered off...
I miss my tablet. I've been using my son's old one and it's screen is too small and it doesn't use the S-Pen and...

Have you gone into the device manager on your computer and told it where to manually locate the drivers?

I think so.
Anyway, I had ordered a replacement tablet and it came yesterday and it has the option to be activated on Verizon, should I so choose, so I am going to get rid of this tablet and not worry anymore about it.

Mine does the exact same thing.
I think the actual problem is that the tablet and charger need to be able to "talk" to each other, and if the USB port is fubar'ed, they can't talk.
This tablet has some VERY strict charging requirements; every thread I've been able to dig up all but DEMANDS you use the charger that came with the tablet. The battery is SO F-ING HUGE that most chargers just can't keep up. (Look around at the battery mAH ratings on any other tablet; they're usually in the 5000-6000 range; the P607T is nearly 9000.)
(you mention that you bought another tablet; I'm posting this so that others might keep up...)

I had this problem even after changing out the USB port, unfortunately. (Actually, it wouldn't charge at all with the broken USB port, but would with the new one...just only when off.)

I had it work just fine for nearly 2 years using a Samsung charging cord and appropriate plugs...they have to be 5 Volt plugs, not 2.x Volt plugs. Not-Samsung charging cords were a hit or miss...with all of our devices...so it was just easier to buy Samsung cords.
Oh, and I replaced it with another 2014 Note, just a Verizon one instead of a T-Mobile. (Not that THAT matters too much as I don't currently have it activated...and will probably activate it on ...gasp... Tracfone!
