Possibly Bricked T-Mobile T989

So I flashed the cm7 alpha that came out last night this morning. I wasn't getting calls so i turned it off and tried to reboot it into recovery. The phone never got into recovery (I told it to reboot into recovery from clockwork mod), and now it isnt powering on, at all. I've tried every key combination, recovery, download mode, letting it charge for HOURS, and still nothing.
If anyone has any ideas, please let me know. I'm trying to gather the files I need to see if odin will recognize it and possibly be able to restore it to stock. If I can't get it to work by tomorrow, I'm just going to go to the T-Mobile store.

Would it be possible that you tried so many combinations that the phone's battery has died? Have you tried plugging it in and seeing what happens?

charged for four hours and nothing.
Took it to a tmobile store and they're doing a warranty exchange since they couldn't get it to do anything either, even with a different battery.
Kind of curious as to what'll happen when I send it back since it has cyanogen mod 7 on it and its rooted. Then again, the phone won't boot, go into download mode, or recovery.
edit: I'm thinking the phone won't charge because of the custom kernel in cm7. Don't know how I would flash a kernel if I couldn't get it to boot though.

Dam,, too late
But for reference try!
Take the battery out and let it sit for a few min the put it back in and see if it boots.
If it still will not boot
Take the battery back out
Plug in the USB cable connected to the computer
Hold down the volume up and down then
Put the battery back in.
You should get the option: Volume UP / Volume Down for Reboot
Hit Volume UP and go get some Odin love!

I still have the phone, I'm gonna try this now. Will update with results.

I did not see you mention it, but did you try the "10 second" power button hold? You know it works when the phone vibrates 3 times. Simply hold the power button until it vibrates. It takes about 7-10 seconds (although when you think your phone is bricked, it feels like it is taking 5 minutes). If it vibrates, you are in the clear. You can usually get to recovery or odin from there. Try doing this on battery only first.

no cigar with the hold for ten seconds method on the power button.

It is really, REALLY difficult to brick a phone unless you are changing the radio (for example, flashing a wrong or corrupted radio). A kernel can hose your phone, but not brick it as you don't need a kernel to access recovery. A bad recovery could also brick your phone, but then you have download mode (Odin) to access that bypasses recovery. In other words, there are layers of protection or access points. We have not flashed any new radios for our phones yet, so you know that is not the problem. Having said all that, that does not mean you are not bricked.
To be clear on your position, you are getting no power response at all? Again, try this:
Unplug your phone;
take battery out (wait about a minute before replacing battery);
replace battery;
"10 second" hold until phone vibrates 3 times (or vibrates at all for that matter);
If you see no sign of life, then try the above process with phone plugged in (try plugged into computer and wall socket separately). Odin recognizes when you are plugged into computer and the boot process goes differently.
As for Odin bootup:
Load Odin;
Plug in your USB to computer;
try the volume/power boot up;
if that fails, try the "10 second" hold boot up with Odin running on your system and phone plugged in.
Outside of that, I can not think of any other way to get you to recovery or Odin.
I have flashed my android phones probably 150+ times in the last 2 and a half years and never made a brick. I thought I had, but was always able to get to recovery or bootloader (think Odin for HTC), and recover the phone. The only times I ever saw anyone truly brick the phone was when flashing the wrong or bad radio for their phone (radio is your 4G / cell receiver). So, walk through your processes to recover your phone in a methodical way and if that all fails, then return it. If you can't get it to go trying all these techniques, then T-mobile probably won't be able to as well and see that you rooted it.
Hope this helps.

Slightly off topic but if you send in a rooted phone for warranty (not insurance, warranty) they will charge you a full repair fee.

What happens when you pull your battery, put it back in and attempt to turn your phone on?

@PorchSong, I've tried everything you said to no avail. I know its extremely hard to brick an android phone. Having had over 10 devices in the past year, all running custom roms, I've never bricked one either. This is why I find this so unbelievable, I usually don't make posts on XDA, not for lack of caring about the subject matter, but rather because I'd rather learn about it on my own to further my understanding on it.
Again, this is as bricked as I've ever seen something. The phone simply is unresponsive to every method I've tried.
@btyork, how would they know if the phone doesn't boot into recovery, download mode, or into regular android? I'm not saying that they couldn't. I'm just saying, what precautions could I take against them finding out. Trust me, if i could find a way to, I'd restore it to stock before I sent it back to them. (I still have the phone and will until december 6th, when they send me my new one, so we have a little bit of time to work on this)
@ mikeyinid, Nothing at all. Nothing in this thread has made the phone give even the slightest response.
The last thing I did was try to boot into clockwork mod, rather than boot with the key combination like I normally do, i did it directly from rom manager. Except, it never booted into recovery, so I pulled the battery and tried to start it again, from there it hasn't booted, or charged. I could've sworn the phone had at least a 30 percent charge when I was doing all this as well. Not the best for restoring from a backup in clockwork mod but I was in a bind as I was about to leave somewhere for roughly two hours and needed a functioning phone (cm7 did not let me make or receive calls, for whatever reason).

Are you seeing anything on the screen?

Are you sure you flashed cm7 for our phone? Sounds like a boot.img flashed to the wrong partition. I only know that because I bricked my first gs2 using the wrong mount point to flash a kernel. If it doesn't do anything at all, jig might work but idk. I just got a new one
Sent from my SGH-T989 using Tapatalk

Typically with Samsung phones, if you can get ANYTHING at all to show on the screen it is not bricked.
Do you have a G+ account? If I can see what is going on while I walk you through it it would be easier. Could possibly hold an open hangout so others can join in and help or just for informational purposes.
I have had soft bricks on my behold 2, vibrant and SGS2, over 100 times all together. Sometimes it takes a little fiddling, my SGS2 seemed a little more difficult only because of the relative simplicity of it compared to the others.

That depends if they can tell or not.

Okay, well I'm going to try and fix it in Odin one more time tomorrow on my friends computer (I use a mac), so I'll report back on what happens. I'm thinking I didn't put it into download mode the right way when I tried it the other night. I remember having to do it for rooting the phone, but hadn't done it since, and since this is my first samsung phone other than the nexus s, I wasn't all that familiar with it. The google + idea might be a good one. I'm not sure how to go about setting that up, but I should be at my friends around like 12est tomorrow, so if anyone wants to set something up we can do that, or I can just report back. Either way, I'll come back to this thread and give a conclusion on what's happened.

Let me know, G+ is easy. Im out of class at 2est.

Just FYI. I ran into this exact same issue. After charging my phone all night and using it for about 5 minutes, I set it down then picked it up like 30 minutes later and received absolutely no responsiveness from the phone. It wouldn't even recognize the charger when I plugged it in.
I tried all the battery tricks, and reset tricks and nothing worked. So I took it into the T-Mobile store, assuming it was bricked, in an attempt to get it replaced. He simply plugged the phone into the stock charger that came with the phone and it indicated that the battery was just completely dead and needed a charge.
It turns out that the phone really didn't get a full charge after being plugged in all night to my GF's MT4G charger. Apparently this phone is picky about what charger is used. I'm sure you've already attempted this, but just make sure to plug it into the stock charger to see if you can at least get the charging battery image to pop up.

more like it wasn't plugged in properly to begin with
because that happened to me, even though it said "charging"... it was stuck at 43% for like 4+ hours, so i figured something must be wrong
and indeed it was, so i unplugged it, and plugged it back in, then voila! now it starts to charge as it was supposed to.
the phone is not picky by any means, i've used my old BB charges with it, the other HTC charger, the other samsung USB, the generic cheap chargers i get from Deal Extreme, etc
they all charges the phone just fine and fast
you do have to be careful when you plug it in, and make sure it's really charging

[Q] Galaxy Nexus is bricked. Any ideas?

Hi,
About 1,5 months ago I received my first Android phone, a Galaxy Nexus.
I have unlocked the bootloader, rooted it en eventually installed Clockwork Mod Recovery following guides on this excellent forum! Everything went perfectly and it ran very smoothly in that state for about half a month up until yesterday.
I didn't have any custom roms installed, so I received the notification for the Android 4.0.2 update, it failed because of Clockwork Mod which I later found out. So I set about to manually install it, I downloaded the image from the google site and placed it in my home directory on my Phone, when I then wanted to restart to start in recovery mode it didn't do anything.
I tried getting the battery out and in, sim card out and in, recharging it,...
It does nothing, not even a small vibration signaling the phone is trying to start.
Anyone has any ideas to fix it, or might it be possible to send it back to the shop ( even though it is rooted etc. ?)
Thanks in advance,
Exatto

You need to get the stock images and flash using Odin or the ADB/Fastboot method. After which the phone will return to stock. Then you can root and do what you like. Lots of guieds on here on how to do it. Good luck.

By the way if you send back a rooted phone they will tell you to take a jump. Rooting voids the warranty.

No response at all? A real brick?

Can you get into download mode? If you can you can use any of the methods above to sort it.

I don't think there is a real brick. There are restore images. Extremely hard to brick a nexus...borderline impossible.

Yeah I have never heard of a "real" bricked Nexus.

No, that's the point. I can't get in any modes. It does't react at all. I think it might be a hardware fault, a friend suggested it might be due to a short circuit battery.
I just followed this guide (http://forum.xda-developers.com/showthread.php?t=1419170) to update, using method 1, having clockwork mod installed. And when I shut it down to restart in recovery mode it suddenly stopped reacting. I have had this before, but then taking the battery in and out fixed everything. Now it doesn't anymore.

Cool, well if removing the battery for a few minutes doesnt sort it then you should be able to return it because the carrier won't be able to tell if it is rooted if they can't turn it on.
When you charge it do you get the charging battery icon when you press the power button?

No, not a charging sign. I hope I can return it, but what if the battery is faulty and they just pop a new one in and then see that it is rooted?
Thanks for the help.

Could well be a dead battery dude, if you have a mate with a Nexus you could try yourself first. I know what you mean about the guy in the shop seeing the unlocked bootloader if he tried a different battery but you may be lucky in that he might not know what it is or you could just grab the phone and leg it ha ha
I hope it gets sorted and be sure to post here what happens. Take it easy.

Will post the outcome.

As promised the followup:
Luckily they didn't notice my GN was rooted etc. as today I received a brand new one after I sent the broken one in to an official Samsung repair center
I did test some things before I sent it in though, a friend just bought a new one and we tested if my battery worked in his phone (it didn't) and we tested his working battery in my phone (it didn't work either), so something was definitely very screwed up.
Haven't got any idea of what went wrong eventually as the repair service didn't offer any details, although I am off course glad I got a brand new one.

hard bricked

well.. i guess from what I've been reading once in hard brick its toast... last night i tried to install the 1% bat mod, and failed. causing my phone to not power back up. at all... I've tried to boot into download mode, and recovery mode, the screen doesn't even turn on. nothing happens. from what I've read on here it sounds like its done. any suggestions? today after work I'm going to best buy and try and play stupid and see if by chance they will set me up with a new phone. I've only had it for 3 months, and I'm hoping since it cant boot at all they will just swap me out. otherwise ill have to pick one up from eBay...

Ok i called and talked to Samsung. told them my "problem" and they emailed me a shipping label, i need to send them the phone and the battery, and they will look into my problem and send the phone back once they fix it. i also told them my battery felt warmer than normal. on a side not, this is a real problem. my phone had been off for 2 days, while on the phone with Samsung they asked me to take out the battery, and i noticed the battery was actually quite warm, struck me as odd considering the phone has been off for days... i told them that too.. anyone else have that problem?

It's obviously doing something... Try to force download mode like this:
Hook up the phone with no battery inserted
Hold Vol Down + Home only
Insert battery

Ya if the battery is still warm, it is doing something. I'd try every absolute way to boot to download or recovery before sending it in.

The same thing happened to me. I tried to install the insert coin revolution rom with muti window support. (unable to resist) and then my phone suddenly turned off. I got happy and thought it worked then a couple minutes later I tried everything but it won't turn on. So I gave it to Telus and said that I did a factory reset and then suddenly it turned off and won't turn back on. so they sent it for repair and said it would take 2-3 weeks. Right now is week 2 of 3. good luck.

well my phone was completely dead so I could use triangle away...I'm not worried about it. if they find out it just means they wont fix it for free...
thanks I need the luck, I'm completely phone free... its a funny feeling not having one... no worries though...

Crazy how dependent we are on these things. Too bad a jig doesn't work like on the GS2. That thing saved me when I had to send it in for warranty repair.

[Q] My SG3 won't charge now

Got a new rom yesterday. Was working fine, phone was charging fine. Today After using the phone for about 10 hours it just died. I didn't do anything new such as download any new apks or flash any thing. But it just died. When I hold power it can go to the samsung screen and just die, when I hold power vol down and home it goes to the download screen for like 5 sec and dies, when I go to cwm it dies in a short time as well.
Now I have it wall charging and I'm getting no LED light, so I'm worried!!!
Any recommendations?

Depending on what rom. Some don't play well with the led. Also you have to make sure it's checked in the settings.
Have you tried turning it on while it's charging?

Some times it turns on while charging, but will just turn back off.
I'm using This Rom
Edit* the led normally turns on while charging...im not that much of a newb, i'm just thinking I might have bricked my phone.. It's strange that it happened a whole day after I flashed the rom though..

If it's turning on its not bricked at all. It's a charging issue, take the back cover off make sure the battery is making good contact with its connection points. Close it back up and plug it in and let it charge for 30 tp 40 minutes check if it comes on. Sometimes when the battery dies completely it takes some time to get some charge into it. The booting up process uses a ton of power, once on make sure you leave it plugged in and charge fully.

Ok because the one time it actually came on it said it was at 70%, which I'm assuming is totally incorrect. So I will now plug it into the wall and let it charge for quite a while, I jsut think it's weird that the light never comes on (which it normally does).....
thanks for the tips dudes!

I had the same issue as you, the phone will turn on and then most of the time it will turn off during the boot process. If I turn it on in Download or Recovery mode it'll stay on for a couple seconds and then turn off. At best, it'll turn on, get to the home screen and then after a couple seconds of usage it'll turn right back off. Also, did you notice that before the phone turned off it would lock itself and unlock itself possibly showing the power menu to like reboot or turn off and such? That made me think it might've been the power button but I'm not positive.
I could not get a fix for this at all, I attempted everything I could think of. I ran the phone in safe mode, it still did it. I ran a different rom, still had the issue. Ran stock rooted, same problem. Ran stock non-rooted, problem still there. In fact, I talked to Samsung yesterday and I sent it in for the warranty as I didn't have carrier insurance. One thing happened was that while I was in stock rooted, I decided to underclock the phone to see if anything would occur and I noticed something interesting. The phone still had the problem but it would stay on for longer periods of time. This made me think maybe the phone was overheating or the CPU was shutting itself off for some reason. As far as I know from my testing I can say that the problem was hardware related. I should also note that this thing happened to me once a couple months ago but I flashed the stock tar through Odin and the problem disappeared for a short while but it came back and continually did so.
Oh, I also figured out how to get it on for a short period of time. To get it to work temporarily, first make sure the phone is charged a good amount. Plug it in for a couple hours. Next, take the battery out of the phone for a couple hours and remove the phone from the charger, the longer you keep the battery out the better. Now, put the battery back in, and attempt to turn on the phone, if it doesn't work try again a couple times. The phone should eventually turn on and stay on for a short period of time (anywhere between 1 or 2 min and 30 minutes). From here just back up anything you need to and if you are rooted and want to turn it in for warranty or whatnot you'll need to clear the evidence that the phone was rooted.
First off, if you are rooted you'll want to clear your flash counter. Download the Triangle Away apk and put it in the microSD so you can access it easily when the phone turns on. Follow the instructions on how to turn the phone on from above. After it turns on, quickly Run Triangle away and click on the option that says something along the lines of "reset flash counter". Once that is done, turn off the phone and take out the battery so that you can turn it on for the next step.
Next, you will need to download Odin (I believe it is Windows only, if you don't have Windows I'm not sure what you can do as I haven't had to unroot on anything other than my PC) and the stock tar file so that you can return the phone to complete stock. Once you have done this, run Odin and click on the PDA tab and browse for the stock tar. Let Odin do it's thing and once you see it's ready to flash the file, put the battery back in and turn the phone back on in download mode. Plug the phone in and let it sit there for a couple seconds to make sure it won't turn off during the flashing process. If it does turn off try again. When you can get it to stay on for over 30 seconds click on the Start in Odin and start the flash. If it stays on for a while but turns off while flashing, the boot will be corrupt and you will have to try again til you can get it to stay on long enough. Note that if the boot is corrupt you won't be able to turn the phone on to anything other than Download mode and possibly recovery. Once you complete the flashing process the phone should auto-boot and it SHOULD work. That means that the phone should turn on with no problems but it may or may not turn itself off. If it doesn't turn itself off go ahead and use it for a while, but if your situation is like mine the problem will come back eventually. But at least now you can turn it in to Samsung for warranty or whatnot.
And if worst comes to worst you can completely f up the phone while it's flashing in Odin, have a corrupt boot img and then call in saying it doesn't work.
Of course all of this is only if you're having a similar problem to me. Like I said, I sent it in yesterday so I'll post updates as I get them. Hopefully they'll fix it for me!

Nice write-up :good:
@OP If you can't get the unroot process to work (like the guy above me said) just flash a rom made for the international S3, thats a sure-fire way to brick you phone

It was quite a nice wall of text. And oh yes, bricking your phone is a great idea! Say it was an OTA or something haha

Ok so SG3 should have a warranty even though I don't have carrier insurance?
And did you try replacing the battery?

Correct, there is a 1 year warranty on the phone and 6 months on the battery and charger. And yes I switched with another OEM battery and the issue persisted. However, the S3 I switched the batteries with continued to work so I believe it is the phone itself and not the battery or charger. It might be the connector points but my phone did strange things before turning off. It may be a combination of many things as well.

Where exactly did you take your phone to return it? The samsung people are giving me a hard time it seems.

I requested a Repair Service. You can contact them at 1-888-987-4357 and request the service there. They'll send you a UPS label and give you an RMA number. I tried to do it through the site but it didn't work so your best bet is to call them there. It's very simple to do it if your phone is already registered. Otherwise you'll have to give them the HEX number I believe. It's under your battery so just have that ready.

Well if it does happen again, don't brick it unless you can't get it to turn on for long enough to flash stock. Hopefully it'll still be under warranty if it does happen again. And no problem! Good luck!:good:

If think you need to take a deep breath and relax. Try doing some more reading, it sounds like your missing a step somewhere. There's something which may be insignificant but your missing it.

Galaxy Tab 3 in Bootloop

Hello everyone,
I'm trying to fix a Galaxy Tab 3 (p5220) for someone. The problem is that the tablet, when turned on, goes into a bootloop.
First of all I see the "Samsung Galaxy Tab" screen, then it jumps to the android robot standing (I believe this is the screen you see when you boot into recovery mode). The problem is that I can't do anything when I see this screen, it immediately jumps to the android robot laying on its back with a big red exclamation mark above him. Within one second this screen also goes away and the tablet reboots and starts doing the same thing.
I have already tried using the button combination to boot into recovery mode, when I do that the tablet reboots directly after the Samsung screen. So then I don't even see the android robot at all.
Then I tried booting into download mode, and this does work. I tried putting the stock firmware on it using Odin (not 100% sure if I used the right firmware though.). Anyways, this seemed to go as its supposed to go, but after Odin gave the "Pass" notification it rebooted, and started doing the exact same thing.
Does anyone have any idea if this is a hardware problem or can I still fix this?
ps. The person that I'm trying to fix this tablet for borrowed it to someone, and when it returned it did this. The person doesn't have any idea what has been done with the device. But we can be pretty sure that the person who borrowed the device tried to do something with it, but failed hard.
Thanks in advance for any kind of help!

I have the same scenario here as well. I have a friends Galaxy Tab 3 (SM-T310) and it seems to sit at the splash screen and never goes anywhere. I am unable to boot into recovery. I've tried Power+Vol Up, and Power+Vol Up+Home and nothing seems to be working. I am able to get into Download Mode. I have tried flashing TWRP 2.8.3.0 and TWRP 3.1.0 via ODIN, but I am still unable to get it to boot into Recovery.
I have also downloaded the Stock ROM from SAMMobile (I didn't see a US version, so I went with Canada? I figured, why not?) Flashed that via ODIN and I am still stuck at the splash screen.
I even took the back off and unplugged the battery and left it off for a few hours, since that is what the internet told me to do, and it still does the same thing.
I did just stumble across this thread: https://forum.xda-developers.com/showthread.php?t=2618798 so I am going to try CMW and see if anything changes. I figure once I can get into the recovery I'll be golden, but I haven't gotten that far yet. Any assistance would be greatly appreciated as well.

Someone with the exact same problem as me, with the exact same tablet, told that he fixed it by replacing the battery. To me it makes absolutely no sense that the battery would cause this, but I've literally tried everything software related to get this fixed. So I figured, why not give it a try! I'll post here as soon as I get the battery here.
Thanks for your reply, and let me know if you get it fixed!

I have seen people pull the battery connector out, and leave it be for a few hours, and I tried that first, but that didn't appear to work for me. Maybe you can try that first before ordering the battery, but if you do get a new battery and that resolves the issue, let me know! You rock!

I had the battery out for multiple days already, so I tried what you said just now. Still did the same thing.. I'm hoping to get the battery today or tomorrow! I'll let you know.

You Sir (or Ma'am, I don't want to assume gender) are amazing! I hope that works, and if so, I'll have the guy order a battery and then I'll throw it in for him as well. Hopefully we can figure this thing out!

I identify as an attack helicopter
Anyways, got the battery and unfortunately it didn't solve the problem
I'm going to see if I can fix it any other way, but I wouldnt know where to start...
You got any luck yet?

I haven't really tried anything else yet, I was waiting to hear back from the battery. I had high hopes for that. Does your battery ever look like it is charging? The one I have here just kind of sits there and doesn't appear to display the "Charging Screen" it just has a battery symbol with a circle on it, but nothing moves. It isn't mine so I don't know if that is "normal" behavior. The stock battery doesn't look swollen or anything, and even though it doesn't appear to charge, it still holds a charge. I will start posting links to things I try. Maybe we can figure this thing out?

My tablet doesn't even show a battery icon.. I think yours has more chance of getting repaired than mine hehe.
Yours sounds very likely to be the battery btw. You flashed a custom recovery right? How did you do that?

I can get into Download Mode, and Odin will tell me it is flashing things, I even get the little progress bar along the bottom and it will reboot the device once finished...it just never boots into the OS, and I can't get it to boot into the recovery once flashed...so I have no idea what is going on. It makes me angry, like a clown! (Also, clowns are angry.)
I haven't played around with anything today since I'm a little bummed out since they shorted me about 96 hours from my last 3 paychecks at work, so I'm kind of on strike. Anyway, I will play around with it on Monday and post everything I try, and get back to you. Maybe I'll even pull the battery out again and let it sit all weekend before I duck out 2 hours early.

So, I just pulled off the back, undid the battery, and plugged a USB cable into the device for power. Do you happen to know if these will boot without a battery? I ask because it appears to be doing the same thing, so it may well be the battery, but the battery doesn't look swollen or anything, so idk? Thought?

I'm sure you've probably tried this but just wanna be sure... I've been watching this thread to see what things were tried.
When you boot to recovery it is by holding power, vol+, and home...but once the splash screen shows up let off of power but keep vol+ and home pressed...if not it will just reboot. Hope this helps, though I know it is unlikely.
