Captivate Hardware Reset Button

Hey, Just thought I should post this... To reset the Captivate without removing the battery, there is a connection on the board called "TP". It is right below the MMC card and you can barely see it with the phone's case on it. Here is a picture of the rear case removed. The TP is the white dot. It is covered with white paint to avoid accidental connection.

You can stick a needle through and ground "TP" to the side of the SDCard. Your phone will reset.
It's a signal line. and it's separated from bat+ by 1000ohms.

Thats very useful. Thanks!

Will this reset work on "soft" bricks and/or paperweight states?

It will work on soft bricks. I'd like to see how a hard brick would react to UART communications. I've got one comming, so I will be able to tell you more soon.

This is a great find for flashing addicts. Thanks so much for sharing this. When I get to my PC I will hit the thanks button.

I've found it quite useful... but I've been doing some non-standard things with my phone...

That looks sick! Someone's been having fun. Has your phone orbited the Earth yet?

Haha not quite... I've been researching non-invasive methods of recovering bricks, and it requires invasive techniques for analysis. Its amazing how many people brick their phones and how expensive jtag methods are.

Doesn't work on Hard Bricks. Tested.

So is it possible to fix a soft brick using this method instead of making a jig?
On my way home right now, guess I will find out soon enough, thank you

Wasn't quite sure what it was gonna do, and hoping it would magically get me into download mode, where the usb or power wouldn't. big down side, it botch'd something in my hardware, and my battery will no longer charge, can not run the phone without being pluged into the wall or pc. unbricked using a standard ol jig, flashed to 2.1 via 1 click, dunno if it just fried battery or did something else. Any ideas what to trouble shoot first? i've tried reflashing, few different roms, tried reseting battery stats, tried factory reset via settings, and via 1 click with no luck, wont be able to test another battery till tomorrow

You did something else....
I used this method about 50 times consecutively. No ideas for you on your issue.
This reboots the phone and that's it. Its easy for bench testing purposes. How long did you hold it?

Just until the screen shut off, then released, not really what sure happened. Is there something rom side that controls the charging of the battery or is it strictly hardware?
Just hoping battery just decided to die, needed excuse to get a bigger one anyways.
Edit-Yeah definetly thinking battery is bad now, it showed 100% charge this morning finally, but as soon as i unplugged from wall it died, plugged it back in and was showing it dead again. Soo hmm, dunno sound like bad battery? fixin to make the 30min trip to ATT store to see if they can check it or swap it.

just wanted to say, i wasn't trying to imply the reset you pointed out had killed the phone, i just wasn't quite sure what happened, and this had been one of the last things i had done.
I just didn't realize a battery could go that quickly, had it tested today, and the guy at store said i was the first person he could tell without a shadow of a doubt there battery was dead.
1500mAH battery, and it read dead at first then full charge on tester at 28mAH.

This looks very interesting and I would like to try it out. Before I try it, I was wondering if you could explain it more in depth like if the battery should be in the phone, if it is necessary for the battery to be fully charged and if this method will work on all Captivates. I also noticed a number on your sd card slot that is different than mine but I assume all phones have a different one. Thanks in advance

[Q] HTC Sensation XE Dead while charging.

My trusty HTC Sensation XE running ViperS 2.0.2 (S-Off) just died on me.
Last thing i did was charge the battery and it suddenly died. The phone did not come into contact with water and didn't fall. The led light doesn't even turn on when the charger is connected. Luckily my wife has the exact same phone so i could test some things. The charger works fine on her phone. Swapped the batteries and her battery does not work in my phone. My battery works fine in hers. So it must be something with the phone itself.
I've read a lot of stuff on the internet today, but nothing has helped so far. Things i tried:
Booting to recovery (Vol down + Power) does nothing.
Connected the phone to my PC, Doesn't even get detected.
Remove SIM, SD and try to boot (normally and recovery), nothing
If anyone has any ideas i would be grateful to hear them.

I would try this http://forum.xda-developers.com/showthread.php?t=1522351

Hi Shantur. Thanks for the quick reply. I will try this when i get home. Seems promissing.

Hi Shantur, just tried the guide to unbrick my phone. Unfortunantly my phone does not get detected. I tried 2 different PC's and even tried disabling automount like the guide states, but nothing. (See screenshot) I used the Latest Ubuntu 14.04 btw.
Any other thoughts ?

try this
remove simcard,sdcard and battery
charge the device as it is for 4-5 hours and put them back
switch on the device and see if you have results

Hi rzr86, I will try that. So the phone just needs to be attached to the power? It won't be charging if there's no battery. Just making sure...

it charges the device somewhere internally
i don't remember what exactly

I removed the battery, sim and sd card earlier yesterday morning. It had been lying around for hours without power. I connected it to the power supply and left it there for about 9 hrs. After putting everything back, the phone is still dead. Unless anyone has another idea, I'm afraid it's just paperweight...

what about jtag?

Hi Rzr86, I had a quick google for jtag, and it looks like it requires special hardware. I don't know if this is something worth doing myself or if there are any phoneshops here in the Netherlands that could do that.

if you don't have knowledge do not attempt it
just search a local shop which has the jtag machine
but know this
it may cost you a lot

Hi Rzr86,
Thanks for the info. I'm afraid the phone just isn't worth the costs any more to get it fixed.
I already had a backup plan.. It's my wife's birthday today and she really wants an iPhone. So i'm getting her one so i can get her Senation XE
Seemed like a better investment than fixing my own phone and getting her a crappy gift...
Thanks for all the help !!

[Q] Android 5+ Unresponsive/Battery Drain

Having a very strange issue since upgrading to Android L -- thought I solved it switching to franco kernel -- but after 2 days it seems to have popped back up.
Randomly phone will be completely unresponsive via power button or any other means -- I can tell it is still doing things because the battery gets drained (incredibly quickly) and I see notification LED flashing when there are notifications. Only way to fix this is hard rebooting (power+vol down)
Oddly, when I look at the battery AFTER reboot this is how it looks (the empty area is during the lock up)

I initially thought this may be the sensor issue, but with the battery drain I am starting to think its something else (maybe memory leak?).
Anyone else facing this issue or have any insight on how to fix this?

have tried that a few times with no success. Problem only occurs in 5.0+ -- do not have this issue on 4.4 when i switch back over.

I have a similar problem with the phone turning off randomly and then in restart I've lost approx 50% or more battery life. If I turn the phone on and leave it alone for a few hours the battery slowly increases back to where it should be as if the phone can't read the stats right. I was going to sell up and buy a new phone but I love my Nexus and then remembered that Playstore Nexus devices have 2 yra warranty, even if you side load OTA updates.
I'm RMAing my phone with a replacement coming next week. Google confirmed that it was faulty but I suspect it's software and not hardware. To be fair the problem started with 5.0 and got worse with 5.0.1 and a cache delete and hard reset has not fixed it.
Can't wait for 5.1 in Feb but I'm sure there will be other bugs!

I called Google about something similar happening and they told me that if it was related to battery, the battery was only warratied for a year and they couldn't help me as it was out of warranty. Maybe I'll emphasize the restarting part.

It seems to definitely be a software issue -- if i downgrade to 4.4 the problem doesn't exist.

This is what people are complaining about with the "memory leak".
Reboot your phone nightly (while it's charging perhaps) and these issues will not appear. Otherwise, it might reboot on its own eventually anyways.
As you suspected, it's a software issue and nothing to do with the battery. The battery level changing drastically like that is common anytime the phone crashes or reboots itself and will calibrate itself eventually.
Google will RMA for software issues like this just to keep the customer happy but that won't help you in the long run, better to keep your non-refurbished device.

Lines across screen nothing else

So I recently was on stock 4.4.2. Sometimes my screen would freeze, lines would go across the screen vertically & horizontally but I could still see some of the screen I was on. I would simply Hold Pwr VolUp VolDown and reboot and screen proceeded to work. Then i decided to goto Android L. I already had the 4.4.4 firmware but updated to the 5.0 firmware. I then installed the liquid smooth rom. This kept happening and eventually got scared and went back to the backup I had made of stock rom. Then I went to CM12. I liked it alot almost no bugs. But this kept happening. I later began to experience something different. Only vertical lines. Each time they are different. I once waited for it to boot and messed with the volume rockers and heard it go down and then vibrate. So im guessing system still works. I dont know where to go from here. Heres a pic of what Im getting when I try to startup.

Sometimes it is a bit of blue on the side. I know my screen isnt fully dead because sometimes when it starts to decrease in brightness after I booted I touch it and brightness goes back up for a little. Also when I turn it off its black and when I turn it on its the vertical lines. They arent the same each time and sometimes when I boot they become just 4 or 5 fat vertical bars. I am S-off & rooted. I have ADB and fastboot but I never had plugged it into my computer on this rom so i never had time to allow it, but I did turn on usb debugging. I once made it to hbot, the top was a white color and I hit power, then VolDown three or two times and power again and it looked like it rebooted. I bought it from Amazon and their customer support is great. Anyway to get a new one without them knowing I messed with it? Did installing the custom rom trip anything? Last time I was in hboot it was Official and Unlocked. I didnt but it unlocked, it happened when I used firewater. Also if I smash my screen and sent it to HTC(Ive had it for only like ~40 days)would they go digging and find I had a custom rom and flip out on me? All help is appreciated. Also as stated above I believe I never tripped the tampered flag and do have a working nandroid backup. Thanks for your help

Just booted it again it was the lines again but it was red then went to black borders and some distinct purple lines

That happened to me on my LG G2 but thank god it was under warranty. My replacement was the M8 I'm using now and I haven't a problem yet..fingers crossed.
What happened with my G2 is it started to get really warm then the screen went bright bright white. Rebooted and I had permanent white vertical lines on my screen. After a couple days the few white lines became my whole screen.
I was also running a custom ROM when this happened so I'm not sure if it was something in the ROM that got it going or if it was the device itself. But our phones are different makers and brands with different ROMs.
Mine never recovered so thank god for the warranty. Wish you luck

Honestly I doubt it. If the screen is shot there's really no way for them to even see it unless they want to be bothered to hook it up to adb. I had to take mine back in person to BestBuy...unlocked and everything...they saw the screen, tried a couple reboots and a battery pull (like I didn't lol), then checked for water and external damages but there were none so now I own an M8

Random shutdowns to 0% battery

Hello all
I have a G-930F running stock 7.0 Nougat and am not rooted. Recently my phone randomly shuts down and when restarted manually says the phone as 0% battery, despite the phone being on 60% before turning off. I got a 64gb micro SD card for Christmas which is the only major change I have made to my phone. Does anyone know what could be causing this/do I need to fit a new battery?
Please find attached a screenshot of my battery usage.

Could be the battery has failed, not uncommon amongst the S7's from the number of people I see complaining about the same thing
Could try clearing cache from recovery, and even a factory reset just to be sure it's not firmware related
Maybe even flash stock again with ODIN

Thanks for your response
Ive wiped the cache, if it continues will factory reset/flash stock
Might just be easier to get a new battery tbh

Probably, but would suck if you went through the whole process of heatgun removing the back of the phone, killing the IP68 waterproofing, warranty etc, just to find it still did it because of firmware
Probably is the battery though

Where are you (and your phone) when this happens?
It might be related to cold temperatures.
I had a similar issue anytime I use my phone out in the cold, the battery drops almost instantly.

I'm in London and it is quite cold, I'll take note of the temperature when/if it happens again, maybe even turn up the heating hahah
It happened today afternoon and it was very cold, and this morning where it also was quite cold so this could play a part, weird tho as I'm also in Sheffield where it is also quite cold and this problem didn't occur

I'm right on the coast of the North East UK and it's snowing and icy outside, very cold in the mornings in the house before heating comes on, and no issue with the S7 battery (My iPad screen is so cold it needs wiping before I can use it, like condensation over the screen)
Although if the battery was on it's last legs anyway, it's possible the cold could affect it in ways it wouldn't to a healthy battery

I don't know how accurate AccuBattery is in telling the health of the battery, but it is in very poor condition, I've also reformatted my sd card, and the phone has not yet restarted (fingers crossed), will probably replace the battery in the new year

I've been getting the same experience .. I live in NL and it's not that cold .. the last time it happen was just now, and it's 12 degree outside ..
I think it got something to do with the last update (that was the last major change I had) ..

So yesterday it happened again so I removed the SD card however about 2 minutes ago it happened again, so I think it is due to the battery itself, will have to replace in the new year since I made my warranty invalid by getting my screen replaced and they removed the gold sticker on the inside

I have now replaced the battery, turns out the original had swollen quite considerably, as you can hopefully see in the pictures. The battery should be as thick as the black section and the grey part entirely on the bottom face.
Will report back if random restarts/switching off still occurs

Yea that's when it starts filling with gas, the plastic casing is airtight, but the gas is flammable if it leaked, I've had an MP3 player do that and the battery swole up so much it popped the front off the MP3 player, it was almost rounded
Hopefully your problems are solved

been two days no issues so the new battery seems to have done the trick
i did tweet samsung about the swollen battery, they gave me a call but since i did the repair myself they obviously won't look into it, but didnt answer my question about whether or not this was a known issue/could it happen to other people etc

You solved it allready. ...

yesterday I received a software update for the phone ... so last night I let my phone run through the battery ... this morning I woke up and it still on with batt level around 39 percent ... before, I could never reach 50 percent .. It would go from 60 something percent than suddenly died ..
