Reboots after I remove the batter

What the heck is going on?
I'm pretty sure this has nothing to do with the ROM, because it did this with the factory ROM, Manila 2d and now WM6.5.
I turned the phone off, unplugged it, removed the battery. I put the battery back in, replace the cover and press the power button. Nothing happens. I plug the phone back in to the wall charger and put power, it turns on....for about 3 seconds then reboots and it would seem that it will do this for as long as I let it go. If I unplug the phone while this is going on, it will die.
The last time this happened, it took it about a day and a half to sort itself out. It almost seems like its a battery issue.
Any thoughts or ideas?

UPDATE!
I took the sim card out of the phone for a few seconds and the phone seems to be working now.... But its been up and running for about 20 minute now with no sings of acting up.

mine started doing that today. went to use the camera and it reset then when it came back on it said battery was drained(this happened around 1pm and i always get a full day out of battery) and reset. have it on a charge right now but will not turn on. took out battery and put it back in with no luck. i will try to fully charge battery and take out sim. if all else fails i will try to hard reset. thanks

tried to charge the pda all night the light stayed orange and never turned green indicating full charge. tried hard reset and when it goes in to prepare rom it shuts off like dead battery. when i plug in the pda to charge battery and then turn on the phone it freezes on splash screen. if i turn on phone then plug in to charge it acts like i havn't pluged in charger. is it the pda or battery?

I am not 100% sure on this, but to me it sounds like the battery.. and that is a MUICH cheaper option to test out... unfortunatly you ahveto wait for shippng typicalyl unless you have a friend who has the same phone.. I got 2 backups and a stand alone charger now... The other option could be your USB port... I have not heard this specific problem with them.... but I am a PC tech and have seen very simmilar problems with laptops... Usually the first think to for is the power port... Just like out phone, if the device is not on a flat surface and such when it is plugging it, it tweaks the port and it eventualyl breaks... on laptops it is not uncommon that when plugged in, the LEF wil light up saying it is getting power to charge, but it enver charges the battery, and even sometimes can;t power up the full system.. .It sort of sounds like this is what you phone is doing as well.. .If that is the problem the stand alone charger would work (my son broke off his usb all together and now syncs via bluetooth and jsut changes batteries.. he has 3 himself as well) If you search online, you can usualyl find a kti with a battery or 2 and a charger/dockign station for under $20US total. Good luck!

tried bootloader and installed official att rom and never shut off. when it was finished with install same issues appeared. help

For anyone facing this issue I would not recommend wasting money on a new battery as this issue has been around with few users since the Kaiser "Tilt" first came out and I've never seen ANY reports that a new battery fixes this. People have bought new batteries, fully charged their battery from a docking station, tried their friends fully charged battery all with the same result. I had this power down issue a Looong time ago my first week in with the Kaiser and managed a fix and am using the same battery now. Although it seems the battery is not being fully charged it's important to leave it charging until you'd assume it's fully charged and get into bootloader mode and flash an official htc Tytn 2 rom. It should flash completely, and the fact that it does not die immediately as on normal boot indicates it is not the battery but the rom. It did take me the whole afternoon of Flashing, recharging and repeating before it finally kicked in. Also, from reading older posts, it seems most if not all users like myself fixed this by flashing the older official htc wm 6.0; worth a shot at least.

Yup, that is what I had to today (I hard reset, actually), with barely enough battery life to do this.
Then the bloody unit came up and was charging - amazing, really!
(Was using the official HTC 6.1 upgraded WindowsMobile OS)

here is my 2 cents....
I owned five Tilts, replaced four of them with warranty issues ... so i have faced this dilemma on at least two of them.
First see if the USB tongue is loose. To do this try to gently tap it with the stylus. If the tongue inside the USB port is loose then you will be facing rebooting and other issues and troubles in the future. The USB tongue gets used and jerked every time you connect your device to your PC or wired headset. If you are still under warranty and the USB connector tongue is loose I recommend returning the phone ( if you still can) and getting a replacement. There is no easy fix for a loose USB connection tongue as i have taken one apart and it is very difficult to repair or replace and very easy to mess it up further.
So, my advice to all Kaiser owners... be careful when plugging and unplugging your phones through the USB. Do it gently as the connectors are very fragile.
For those that have the above issues, I recommend using a separate battery charger tray, avoid plugging the USB as much as you can, and if you must, then administer extra care. The rebooting will stop if you plug the USB cable to the device and move it up and down a hair then holding steady. And most likely you will not get a full charge or even a partial charge. The biggest culprit to this problem is car chargers, and second, is inserting the stylus by mistake (when it is dark and hard to see) in the USB port instead of the Reset hole by accident.

Please Help!!!My phone is not switching on!!!Urgent Attention needed....

Somebody please help me, I was talking on my phone for around 4 hours using SKYPE via WIFI and the phone was charging. The phone went off, and I can only see a RED light on the power button when the phone is in charging state...I cant switch on my phone!!!My phone is under warranty but I have flashed my phone with a custom ROM so now I wont be able to take it to a service center!!! Anyone please provide a solution to Switch on my phone....It was very hot when it went off....Please guys please help me...

Just make sure the adaptor is plugged into the wall and let it charge for a while (say 15-30 mins) without touching it. It sounds like the battery is almost fully discharged.

I think so, but when the it went off, it was connected to the charger and I was talking on the phone simultaneously. I didnt get any warning sound or message when the phone went off...

Are the charging lights flashing on the phone?
if they are not and the plug has not come loose you might have a faulty charger or USB cable. You should be able to buy both pretty cheaply if its not in warrenty still
Other rhings to try after lettting it sit charging for a bit try a soft reset or remove and replace the battery, it just might of crashed. Or failing that if your really concerned try a hard reset.

Thank god, finally the phone powered up after a few minutes of charging,but when I switched on the phone and checked the battery status it shows 66% charged...How come that happen??I think it wasn't a battery issue...Is that because of overheating???because my phone was very hot when it went off...
Thanks for your Reply man...

No problem glad your phone is working again. You might be right there might be overheat prevention mechanisims or software in the battery, if so its a good bonus, just watch those long skype chats lol.

Thanks hungry...I will take up your suggestion,usually I dont use my phone for long chat sessions but unfortunately my PC broke up and I had to rely on my phone...I wont repeat it again, my xperia is a precious thing for me right now and I cannot afford to lose it...If there is an overheat prevention mechanism it's really good because there wont be much damage to the motherboard or circuits due to overheating....Thanks for your assistance mate..

Battery isn't charging?

So i messed up my phone...and it won't get past the motorola screen when you turn it on...i figured out how to fix it however my battery is too low to do it...so i plug it into the wall and again it just turns on to the motorola screen and thats it and it doesn't seem like its charging....does it not charge when its at this point?

Your battery is too low to flash, but you can't charge because it can't get to the screen. Trust me, was there two nights ago.
Check that thread, find an old USB cable (I used a USB to USB A mini, worked fine). Took a couple times to strip it, lost about 4 inches in it because of it. Worked like a charm. The issue you'll find is you'll need to strip about 1/4 of an inch of cable (exposed wire). from there, you'll need some tape. Take it and follow (red to +, black ground to -). You'll fail about 6-7 times where one wire slips out. Then from there, jam that sucker into the back and try to get it so it'll rest right under the camera area. That should be enough force for them to connect and then you can get into fastboot since you'll have +5V direct flow.

Not sure about the bionic...but when i fked up my DroidX like this, it would charge when i left it off and plugged in. Don't even turn it on, leave it off and plug it in and wait a min to see what it does (my X came up with a battery screen). I left it for a lil bit to charge, then ran an sbf through it.

My understanding is you can apply more than the max the phone was designed for, 5V at 850mA, to the USB connection. I am just a little weary of what I apply directly to phone innards. There isn't really documentation on what the circuit can handle.
I have a connection I could use that pushes a bit more current.
What is the maximum current you can apply directly to the phone's battery connection terminals? Will 4.5V at 1.5A be okay? Do I have to find an old USB wire and run the standard old 5.1V at 500mA from my computer?
/*Edit: If the 1.5A is too much, and I ran that in series with the battery, (IE, stuffed the wires into the battery terminals, and jammed it into the phone) would that be okay? */

How to unbrick a "dead" Milestone.

After an unfortunate rooting session with my Motorola Milestone, the phone now returns into an "dead" mode. It refuses to start at all. I tried charging it and see if it starts by itself, but it doesn't budge and the little while led doesn't lit. The only time when it lit is when I connect it to the PC. I tried putting in it a new battery, taking out the SD card and SIM, but to no avail. I remember seeing a video where a guy used a dissected USB cable to spark the phone into turning on again, so I take it I'll have to use a "hardware approach"? Please help.

I tried following this guide, though without success. The phone still has that white LED lit when it's connected to the PC.

After a reply on this thread I also made, it might be possible that the battery is charged, but the phone refuses to boot at all. Is there any way to unbrick the phone in this state?

Do you think your device is really BRICKED?
If so, you can try to flash your original sbf file into your phone. Guide here: http://forum.xda-developers.com/showthread.php?t=696845
If you are using a Linux, google for "sbf_flash".

I agree with my front floor..ermm, u dont need to worry about its 'dead'. just flash original sbf can rescure your phone.

I had the same problem too, but good news is I tried to revive my phone successfully recently, btw your phone is not 'dead', it's just staying in limbo state, the solution is to pull out the battery and don't connect to any usb, don't try to power it up, it must be completely out of power wait about 12 hours, and then try to power your phone, I think there is some capacitors in the phone which retain the phone state, to make it out of power will wipe out it's state, good luck

"My phone is in limbo state... "
That's a pretty cool statement.
From technical view, it might have happened that something caused a kind of deadloop when reading scratchpad SRAM inside OMAP processor.
This SRAM, as well as the internal RTC is powered by a small battery soldered on the mainboard, while the phone is shut down and the battery is taken out.
What you did was, to wait untill this battery became uncharged.
All SRAM and RTC setting as well then gets erased.
Afterwards the CPU will start up with empty scratch SRAM, might be called a "real" cold boot
Normally the phone should not behave like this. Even if SRAM is not valid the phone should boot up...
...but anyway as you observed it like this, it might happen.
@andoruB:
Apart from that, the Milestone is hard to brick in general.
Might happen though, if you do evil things while flashing new firmware.
Especially while flashing bootloaders...
If you got some more information about the things you did, would be helpful!
Good luck anyway!

how did u root it? can u give a more detailed description? and hows ur phone? sometimes, the milestone would just shut off and wont come up if the battery is gone. Try charging it for maybe 2-3 hours, untouched, and see what happens.

Have this exact problem. Was doing a nandroid recover when the phone got stuck. Pulled the battery out. Placed it back in, pressed the power button. Nothing.
Led lights up only when connected to the computer's USB. Battery was charged before Nandroid recover. Used nandroid a lot of times but for some reason, my stone stopped playing nice.
I just removed the battery. Hoping this works. Can someone please post if you got this same issue resolved? I like this phone no matter how slow it goes sometimes. Thanks!

I completely forgot about this thread, sorry guys!
I don't remember exactly what happened, it's been so long... but I do remember I left the phone "inactive" (it's not like i had much of a choice! XD ) for 1 or 2 months, with the battery out. After I got hold of a wall charger, I plugged in the battery, after I plugged in the charger, and what do you know? It worked! It started charging (was 60% charged, fully charged, I unplugged it, but after putting it to charge again just to make sure it was fully loaded before I would flash a new ROM, it was charged up to about 80%, weirdly, so I guess it was a weird battery problem)
I do remember I didn't do anything to it, so I'm not sure what to tell you guys to do, except leave out the battery for a month or so ^^;

Xperia T - stock, not rooted potentially reversed USB connection, now won't switch on

Hi
I’m wondering if anybody has any advice regarding my problem. I have looked here and tried what has been suggested.
My stock, never rooted, never flashed, Xperia T (think it was Android 4.3 but can’t now check, the latest Sony rolled out) was working fine until yesterday. I was on a plane and noticed it had 20% battery life left so I plugged it into the onboard USB port. The problem is I think I hay have plugged the cable into the port the work way round – not the connection on the phone, but the actual USB socket. This should be impossible but somebody obviously had broken the port and it turned out the cable could be plugged in both ways! (I don’t know if it was plugged in the wrong way round but is the only thing that could possible explain the sudden death.)
Could this have bricked it? I suddenly couldn’t get a red light to show charging and holding down power on and volume up or down does nothing. I tried charging overnight via a wall socket when I got home but the result is still the same. Just a black screen and no sign of life. I have also tried plugging it into a computer with Sony’s PC Companion but as the phone is not ‘on’, it can’t be found.
Does anybody have any advice where to go from here? I’m more concerned about some recent data from holiday on the phone than the actual handset itself. If the phone is dead, is there any way to read the internal memory?
Thanks

Try this: Unplug the charger, press the power button. The phone won’t power up because there is no charge left in the battery. But press the power button along and while doing so, connect the charger without releasing the button. Now, you will probably see the red light. Please don’t take off your finger from the power button for around 1 to 2 minutes when the red light for charging will glow continuously. If you feel tired holding it, you can try sticking a tape on it in it’s pressed mode. Once you are sure that the phone is now charging the battery again(red light keeps glowing even after the power button is released) kindly wait for 5 to 10 minutes or may be more before you press the power button again to power the phone up. Now the phone will be up and running
If that doesnt work maybe ur battery is dead or usb port broken

Thanks for the advice. I gave that a go after trying a 24h wall charge and not touching it (which did nothing).
So, I held the power down, plugged it in but nothing. I held it down for around 5 minutes both manually and then repeated the process using the rubber band trick to keep the button held down but no red light ever came on. I think I’m going to try a new battery as I genuinely see that I have nothing to lose as I doubt it will be possible for anybody to recovery data given as the phone can’t be switched on so if I break it further I’m in no worse position!
Thanks again for trying to help though!:good:

When I got my xperia t it was in described condition. I also tried everything (rubberband trick and so on) but the only thing working was to open it and pull and put in again the plug of the battery. After that it booted immediately and I got this sleep-of-death-thing nearly every day... Since I soldered the battery as described in this Topic it happens only ~once a week. Good luck!

SOLVED! In preparation for the new battery arriving, I decided to take the back cover off. I unhooked the top battery connector and decided to connect it back up again, just to see if it did anything. Plugged in the charger and a red light came on straight away! I let it charge for a good couple of hours and switched it on – not as easy without the case attached – and it worked. I’m so frustrated with it being such a simple issue as needing to disconnect the battery but even more frustrated with the design that it is meant to be a ‘sealed’ unit with a non-removable battery. I used to often need to disconnect my old Omnia II battery to restart it but that was a simple case of cover off, remove battery, replace battery , put cover back on, not the creaky, back cover fear of cracking exercise of yesterday. Still it’s working now and hopefully life in the old phone yet!
