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

kaiser won't turn on

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.

[Q] Droid 3 bricked

My droid 3 will not boot, if I plug it in to my computer, it will not turn on and it will show no screen, it all happened after I restored my phone on a low battery. It is missing certain files like the bootloader so i can't restore the rom on the phone. What should I do?

Maybe it needs to charge. Plug it into a wall socket.

Well I need to get the phone back up and running and the bootloader as well as the charging program is missing. I have a brand new battery for it. It is fully charged.

I got the phone up and running

The problem was when I originally tried to flash it... it failed due to dead battery... WORST MISTAKE EVER... so I purchased a fastboot cable and tried to get the phone up and running but it was mounting the device in windows as OMAP4430 so I tried again last month and I got it back up and running with the latest version of android... the one that came with the device.

I AM SO ANGRY AT THIS PHONE.. IT WILL NOT EVEN BOOT IN TO ANDROID!

I'm having a similar issue with trying to fix a friend's phone that only displays the "Dual Core" logo when plugged into the computer. The computer itself doesn't appear to register that the phone is connected so doesn't show up in device manager that I can see. Plugging into a wall outlet doesn't light the device screen up, only the computer (Win7 box). I believe he dunked the bootloader, and it's bricked, but I'm trying to fix it anyway. Anyone reading this, I would appreciate any useful pointers or suggestions. Thanks all.

That occurred to me as well, I'm going to first see if the local Verizon store can charge it (or even replace it) for free. My friend actually did manage to score a power cable, but I'm not convinced yet that that is what I need (since I'm getting nowhere with it). I'd like to eliminate the battery as an issue if possible first before spending any money.

Verizon will not replace battery for free, if phone is more than 1 year old
The software that charges the battery is very easily corrupted, can be reflashed with firmware, but need a charged battery.
The TBH factory cable adaptor will power the phone direct from usb port, no battery is even needed, then firmware can be flashed and charging will work again.

I've actually gotten a battery in the past for an obsolete phone, but out of packaging and possibly used. My friend acquired a power cable (not sure from where) which just lights the screen as described above (with or without battery installed), but turns off as soon as I unplug it, so I have my suspicions about the usability of his cable. I struck out with the local Verizon store, so will just order the wall charger and charge the battery next. Crossing fingers... Thanks for supplying that link tho, that's the one I will use.

Follow-up: It took 3 weeks to receive that battery charger from Singapore of all places, but it worked. I didn't charge it up all the way, maybe just to 50%. The phone with battery immediately was able to boot into fastboot. Using rsdlite and motohelper installed, I had the phone back to fully functional within 15 minutes.

Great, thanks for the update.

One thing you should check.
Is the battery bulged on one or both sides?
If you lay on a table, does it spin like a top?
If so battery should be replaced.

No, the battery was/is fine (in fact, fully charged afterwards it lasted 2 days on standby). I think my friend probably was just trying to flash a new ROM and didn't notice he had such a low charge. Still not sure why the cable he bought didn't provide the necessary charge to recover, but that's what you get sometimes with aftermarket equipment I guess. Still, it's good to know that is a possible solution for someone else down the road.

Sudden Death?

I left my phone overnight with low battery, the next morning, the phone can't be turned on with only red led charging, very similar to Xperia Z's sudden death.
First day, I was able to charge it and power it up to the CM boot animation.
Then I wasn't able to charge it, however can enter fastboot mode, but not flash mode.
The first night, somehow I can charge it and I left it charged over night.
Second day, out of nowhere, I can enter flashmode for once, but cannot flash any .ftf because some errors with loader.sin. After I unplugged my phone, I can't enter flashmode back again.
And now, whenever I plugged in my phone to wall charger/laptop usb, my phone red led is blinking for about 3s and then off for about 30s. Can't enter flashmode/fastboot whatever...
Is this the sudden death like other xperia z? But I've left my phone battery went to 0% several times before and I never had this problem until now....
Someone please share your thoughts and help me in this.
Your help is appreciated. Thanks.

I think your phone is totally bricked.

I'd hate to believe that it's hard bricked...
I was still able to enter flashmode, even though only once in many tries..

Try flashing a stock/custom kernel IMG through fastboot, charge it up, see what happens. If necessary, flash a whole ROM - try the AOSP Lollipop yuga port we have, it's meant to be flashed via fastboot.

I flashed my previous working nightly kernel via fastboot before, and the device still failed to bootup.
I didn't flash ROM because the device can't even bootup (ought to be kernel fault or some other unknown problems)

Hmm. Try replacing the battery, maybe? Highly unlikely to work, but I got nothing else. I brick my phone on an almost weekly basis, and I've never come across a problem like yours. ?

I think so too. may be battery has past its life. or could be kernel issue. If you able to flash stock kernel or any other then are you not able to power on keeping the phone connected to charger instead of powering up on battery?

Currently I kept plugging in my phone, hoping for that just one time that it might be connected in flash mode, then I can flash a stock kernel+ROM to try out.
On another note, from what I see, it might not be battery issue because I can't boot up the phone on charger without battery. I'm supposed to be able to do that right?

See if your battery's shape is changed or not i.e it is curved.
Normally battery is flat and you cannot spin it on a smooth flat surface. This is a good sign and your battery is in good condition
But if you battery is spinning then it is little bit curved so chemicals inside are not able to create reaction need to power the battery. It won't even last 10 mins even After 3 hrs of charging.
What I think is, your battery is damaged, when you go into fastboot or flashmode your battery dies!
Typical condition in humid climate!
Just another suggestion

Yes, the battery is curved. I can't really remember how it was, but I remember it was slightly curved a while ago.
Now I am having problem to find the spare battery to test it out.
Btw, I am supposed to be able to boot up the phone on charger without battery right?

Battery sides should be flat if you keep on a table or a flat surface. If you try to spin the battery and it spins then there is a swollen bulge in the middle which suggests that battery has gone bad. The chemicals inside are leaking. You must change the battery before it explodes while charging and totally damage phone circuit and might do some harm to you to.
I removed the battery and tried to power up the phone while connected to wall charger but I couldnt which means ZR cant be powered up without battery.
Check online for original battery or replacements available. :good:

Thanks for confirming that ZR can't be powered up without battery, makes me more confident that it is battery issue.
Will look for battery replacement and come back here with results.
Thanks.

Dear All,
Thank you for all the thoughts, suggestions and solutions.
I managed to find a replacement battery for my ZR and it can be powered up again. Hence all my described issues are due to bad battery.
However my ZR now experiences weird issues after back from grave, like WiFi downlink shoots to max for unknown reasons and random reboots (especially on WiFi, random reboots even happens while charging power off). Prime suspects are: 1. I didn't charge my new battery up to 8 hours before use; 2. I kinda broke my kernel or ROM in my previous attempt to revive my phone.
I'm going to reflash my kernel and ROM, and charge my phone overnight. Will let you guys know if everything is fine.
Thank you so much.

I think its a ROM/Kernel issue coz you won't need to charge a Li-ion battery for long time before first use..it should be done for Nickel Cadmium batteries and not for li-ion..so that might not be the issue

Now I can't even boot into my ROM, because the first thing I see before my homescreen is "Powering Down".

Any known cause for auto shutdown?

Z1 Sudden Death!

Hello!
Yes, it's right. I guess it's my turn to get the sudden death of my beloved Xperia Z1.
It's dead, but I don't think it's completely dead and I'm hoping for some help from tech navy's around here and from other people who got the sudden death issue so here's what happened:
I woke up early in the morning at around 8 am and the battery was at 9% and I had no time to put it on charger because I'm in a hurry, so I said I'll put it on charger in car same as always. I use the magnetic cable that I removed from the dock (cuz my sis lost my charging cable, I have to use my magnetic one every time) and I almost always charge my phone in the car with that cable. The phone was working perfectly so I locked the screen and connected the magnetic charger and the charging light didn't come on so I wanted to check if it's charging.... and found out that it's dead (no charging LED, not turning on, no Power + Volume up vibration, no nothing) so I went back to the house and put it on my mother's charger (Micro USB) and got a red LED light as if it's charging, but it's not. still doesn't power up and everything and yes, I've tried the reset button near the SIM card, nothing wants to work.
I took it to Sony service center later that day and they said it will take 3 days because of the traffic they're having, and I have no warranty because I bought it on release which is more than a year ago. After 3 days, they told me that it's a motherboard problem and it got water damaged (while the last time I put it in water was about 2 weeks before that day, and he saw that the white thing is red) and it can't be fixed pay some money and take a new one (just phone no boxing no nothing) and I said no thanks and took the phone to another shop and he checked it and told me that he can't fix it.
I cracked open my phone and I can't see any water damage in it, everything seems to be perfectly fine. I've tried everything I could think of, everything I read on the internet, but nothing seems to work, and the pc doesn't even notice that I connected my phone, I've tried connecting it in fast boot, and flash mode, but nothing works it just keeps the red LED light on. Disconnecting the batter didn't help at all.
I called Sony service center and asked them if I can buy a motherboard from them and they said that they don't even have replacement parts for any Z series phone because they're not authorized by Sony to repair the waterproof/resistant Z series phones (The service center here isn't Sony, but it's an authorized service center by Sony) so at that point I lost hope to get it repaired.
All that happened back in January, but now that summer is here, I want to fix it somehow. But I have no clue where to start, and I'm not sure how to confirm that it's the motherboard that's damaged. is there a way to find exactly where the problem is? I have a soldering iron and everything needed to repair the phone, all I need is to know where's the problem! I can buy parts off of internet, and I will if I need to, but I'm not gonna buy a whole motherboard from ebay because I simply can't trust that motherboard.
Sorry for the lengthy post, and thanks for any help you'll give.
Regards,
~J2C

leave your phone for a weed and try to charge it . if your phone still led light I think your battery die not your phone .

Your battery is dead, if you have taken it apart already just buy a new battery or buy a micro usb lithium battery charger from ebay and hook it up to your battery (by itself) I posted about my experience here http://forum.xda-developers.com/xperia-z1/help/red-led-flashes-charging-solution-t3141345 If you have access to voltmeter you can check the battery voltage, it is like 2.6v or there abouts. Your phone will not charge a battery this far gone.

I don't think that the battery is dead, because:
1- I get a STABLE red light when I put it on charger or connect it to PC.
2- I've tried a method that's said to revive a dead battery on a Z1 (or Z series) and it didn't work.
3- If it was really the battery, then this should've worked! But no, When I connect the motherboard with test point properly connected, the PC just doesn't recognize the phone.

I followed all those methods as well and none worked for me either. Measure your battery voltage with a voltmeter, it is the cheapest way to verify if the issue is battery or something else.

Hello!
I finally got access to a multimeter today and checked my battery's voltage and it was about 3V so I can confirm that the problem is not the battery.
It must be some kind of hardware problem, and I don't think that you really did try the test point fix and you just said yea yea bla bla YOUR BATTERY IS THE PROBLEM! No, it's not.
Any other suggestions?
Thanks!

3v is still to low in my opinion

I've charged it, and still not working.

Bumping cuz I want my good ol' Z1 back

I've experienced a "sudden death" once, it was really scary to me.
I've flashed a custom rom, rebooted and went to bed directly without waiting "android is upgrading" or whatever.
The next day I saw that my phone was not opening. There was no red led to indicate low battery, I plugged to charger for some seconds and didn't see a red light to indicate "charging" so it was weird to me. The solution was to charge it for more than 30 minutes and afterwards it went to 1%! Maybe you should try to charge with the cable like normally and wait for a while

Hope it works! 30 minutes was so long and worrying though :silly:

Nope!
You obviously had a dead battery, and I've already left it on charger for 2 continuous days.
I clearly have a hardware problem. Probably a dead chip as the phone died the moment I connected the magnetic charger.

If u disasassembled your phone then simply disconnect battery, connect phone to pc (with disconected battery) with pressed volume button down, if phone working u should see blue led light (flashmode)-if this happen then your battery is fault (maybe not, try to flash stock rom if u see flashmode), if not then it is mainboard.

I don't think that you actually read the first post, but no problem.
The computer doesn't recognize the phone at all, with or without battery. And I've posted a link a couple of posts back that leads to a "hard brick fix" thread and even that didn't work for me.
Anyways, I just tried what you told me to try, but no. No flashmode, no fastboot, no nothing.

[Q] Sony Xperia Z1 - Completely dead (no led/no nothing)

Hello.
Please take your time to read this message.. It contains detailed information about this case...
I have a broken Z1 phone which I'm trying to fix. It all started with the phone turning off randomly, and wasn't possible to turn it back on. Not using the power button/red reset button or using power + volume up together (this worked previous times).
When the screen died, I could see white blocks of pixels moving around a few seconds before it completely shut down. There were no signs of life after that, the LED was completely dead as well. The computer didn't notice the device if I connected it with a USB cable. If I tried to charge the phone, the LED wouldn't turn red.
I decided to wait for a week in order to see if the battery could run out of charge. So after a week I took the USB cable and started to charge it. The LED turned back on, with a red color, which is correct when it is charging.
I thought it would work to boot - but nope, it did not work at all. Now is the time I decided to open up my device. I used a heat gun to heat the back edges of the phone. I then used some palastic tool to open the back cover from the phone. It all went very smooth and I disconnected the battery from the phone (removed the cable from the motherboard).
I let it be for about 10 minutes. After that I inserted the cable back to the motherboard, and tried to boot. This time, nothing happend again.. So I started to charge it, and a screen came up saying 1% battery... So I let it charge the battery for a few hours until it rached 100%.
The battery is now 100% charged. The phone still refuses to boot up the first time. The second time I tried, it worked. I was able to connect my phone to my computer, so I took a backup of all files. I downloaded Sony PC Companion, and made a factory reset. This went very smooth as well.
I thought everything was fixed after this - but nope. The phone randomly shuts down a few times, and each and every time, I'm just starting it again (it did crash both when I was using it, and when I did not). I was speaking on the phone with it yesterday for 1 hour (used a bluetooth device), without the back cover connected to the phone. The call went very good and the phone didn't crash anymore that evening.
I thought everything was good, once again. So I was letting my phone be powered on during the night when I was sleeping. When I woke up, I went to check the phone - and it was: dead.
Since this, I have not been able to power it on again. No matter what I do. I have tried to disconnect the battery, check for cables that aren't fixed and so on.. But everything seems to be OK.
My thought was that the battery was bad, so I went to a store in order to check if the battery is OK or not. They tested the battery with some kind of device, and said it has about 40% charge left.. And they didn't see any issues with it.
So... now I'm wondering, what kind of parts do I need in order to fix my phone? Is it just a new battery, or is it the whole motherboard that is gone? What do you think? I know you guys are very experienced, so I have high hopes of help from you.
Regards

Hello!
Sorry to hear about what happened to your Z1, I'm currently in the state that my phone has a red LED when connected to anything and stays like that, PC doesn't even recognize it.
I see your problem is different, I'd suggest you to start here and hope for the best. Unfortunately I can't do that to my phone because PC is not recognizing my device.
Good luck
Regards,
~J2C

Thanks for your reply. I have already tried that, however, my PC is not recognizing the phone either - so I'm not really sure how to proceed.

Well, thank you...
I decided to take apart the device even more, and I found something on my motherboard, which probably is rust.

Hello.
Have you tried Volume up + power button pressed together for about 10-15 seconds? Do you feel any vibrations, how many?

Download Sony PC Companion, plug in your phone and follow the instructions in order to reset your phone. If that doesn't work, then you have probably had water or some other hardware failure.

Is this problem will cost me a lot of money if I'll bring it back to Sony for them to repair?

Not if you repair via Sony PC Companion. It will re-install the system on the phone, so in case it is a software error, it will be fixed.
However, if that doesn't help, then you need to check if you have any warranty valid on your phone. Even if you have warranty, it is not sure that Sony will cover costs for repairing your device. For example water damages will most likely be refused, and you'll have to pay for it yourself. I don't know how much it would cost though.
