I dont know if this is common, but my XDA IIs hard resets itself even when I remove the battery momentarily to change sim card. This happens even when the device has just been removed from the charger after having been there for ages (just in case ;-) ).
This is majorly annoying since it means I cannot swap sim cards away from my PC (since a restore is necessary afterwards). I know I can restore from my phone, dont tell me that, its the useless internal battery that bothers me.
I agree!
If the battery is out for about 6 seconds, it's done!
Or, the unit is ON, and the battery falls out... INSTANTLY!
Terrible!
Dumbest design I have ever seen!
The most annoying thing is that when i was trying to do a hard reset once by removing the battery, it wouldnt go! It lasted its full quoted 20 minutes!
I suppose youve just gotta be prepared with a fresh backup beforehand, grrr.
The internal battery is so that it doesn't do a hard reset and wipe everything off of the volatile memory when you pop the battery out; it's not designed to keep your device on when you pop the battery off.
I know that, but it doesnt even do what you said.. (most of the time)

I haven't had a problem with mine; I can keep it out for a few minutes without issue.
Hi:
When I turn on Flight Mode (the phone is off) and when I close all programs before removing the battery, my PDA2K just does a soft reset, not a hard one.
Hope this helps.

Try to check if the backup battery works right... I had this kind of problem when my backup battery didn't work...
Yes, same thing happens with me. This has one permanent solution, upgrade to WM5.

help replacing backup battery
Hello all, I need help replacing the backup battery, and, what type is it?
moving house again, cant find the book.
Also from my previouse Psion Organiser days it was always better useing NEWS PAPER to clean the battery BUT DONT TOUCH IT! use plastic tweezers if you can, and clean the inner contacts with news paper or similar.

It's a boggo standard lithium cell, maxell 1602 or summat, 3v w/tags costs about 3? Open the unit up, peel back the conductive tape, remove the shielding and it's out.

Hi Guys,
Whenever I remove the battery from my XDA 2S I lose everything and have to set up the OS from scratch.
I have spoken to O2 and they have told me this is normal? But how can this be? It is the most stupid thing I have ever heard.
Please if someone could just tell me if their XDA 2S does this I would be more than grateful!
Thanks in advance.

Go to settings/ Power icon and check the status of both the Main Battery and the backup Battery, the first could be at any charge % the backup Battery should be at 100%, this is used to hold the data on the phone for a short duration, sim card swap or battery swap with the machine selected OFF first. If its loosing data then there is something wrong with it, I can remove the Battery on my IIs for 10 mins if need be without a problem - Mike
Yes the Backup Battery is at 100%
It loses everything as soon as I take the battery out, I can put the battery straight back on, start the phone and OS setup begins.
When you say selected "off". Do you mean quickly pushing the power button once.
I have done this and still it loses everything.
Looking forward to your response.
Jonnycash!
All I can sugest are two options
1, Return the phone as it is clearly faulty, demand O2 repair the unit or try for an Exec as a replacement as re-compense, you might get this easily as they are no longer offering the IIs.
2, install something like Sprite back-up and configure the back-up to re-install everthing hardly ideal, and this is not what I would do.
Mike
Yes, I have just got it back from being "repaired". they said that they replaced the circuit board but it still does it.
I will send it back as suggested and try get a new one.
Thanks
Jonnycash
After taking out the battery, try not to push the tab(the one you pull back and the battery pops up) that holds the battery back into place until you re-insert the battery.

Sounds like a duff backup battery to me ( see pic), changing the mainboard would seem a sledgehammer to crack a nut. I have had this with blueangels after re-assembly, even with the backupstatus at 100%. I leave on a cradle charging overnight then do a hard reset - seems to work for me.
Richard
i have that problem as well before. but maybe this will help you a bit.
because i always do it removing the battery when changing my sim card. how i wish they would put the sim card away from the battery. ( calling the attention of the engineers for future references).
i started on the permanent save check mostly on contacts and appointments (I needed them all the time) (start>settings>system>permanent save). then i usually turn on the flight mode then turn off the pda from the power button.
thats the time i take the battery off and either to swap the sim card of the battery. then it automatically go to soft reset when the battery is back you will notice that after the automatic soft reset, there will be a small window showing appointments and contacts restoring.
i hope this will help.
I've had this, once. I've heard that this is a bug of that little black thingey that holds the battery, because it supposed to switch between backup battery and normal battery. Too bad sometimes it does not do this at all...
finally this happened to me to today. I by mistake took the battery out and when I put it there again, it hard resetted itself. Many of my notes were stored in main memory, which I had taken from my teacher just 30 mins ago

It happened to me again few days ago, under 2003SE (I had to downgrade for something). One thing i love in WM5 that I don't have to worry about this.
It has happened to me many times as well as I am always changing batteries. As somone mentioned above it seems to be a bug with the battery holder (the little black tab you clisk to hold the battery in.) I just keep my contacts backed up each time I add a new one. as for the applications they can usually waite till I restore them.

Eeerrrr. how about ' replace the battery' - they are standard cells...
Richard
Mabey its not clear what seems to be happening here
When you drop the unit and /or when you open the little black clip that holds the battery in place. Somtimes the phone looses all stored information and goes to hard reset. There seems to be 2 bugs in action here.
1) The batterys seem to get into a strange state where they dont work properly. (I have found that putting the battery into the rear slot of the charger reconditions it to fix this problem.)
2) Some units seem to have a bug with the battery latch when you open the latch accidently or somtimes even just when changing the battery intentionaly it seems not to switch to back up battery corectly. My theory is that there is a dead zone in the latch that does not make the correct transfer if it isn't fully engaged in either direction. It is a really poorly devised way to handle battery changes but hey its too late for them to redesign it. I can not say how many ppl have this issue or if it is everyone or just some people but I do know this is the case on mines and many of the forums I've read.
Solutions:
1) Back up your unit whenever you add data to it. you can just do a contact list back up which only takes 1 min for me and my sx66 has over 2k contacts. Do full back up once a week that should cover your apps and data.
2) Keep your battery reconditioned at least once a week use the rear charging slot for the battery. If you only have one battery this is not an option so I suggeest if you are going to keep your sx66 for any length of time buy a spare battery.
3) Recently I have begun using a small peice of duck tape to secure my battery latch. It is a pain in the rear but I have droped my unit once in this configuration and the battery and latch stayed in place.
Additionaly:
To make restores easier you can include some of your favorite applications in your ext roms. Just snoop around in the forums and you will see directions for manipulating ext rom.
Also look into changing the directorys where you store information. IE your mem card and the onboard storage directory seem to never get nuked unless it is done by the user.
Anything short of the above listed or replacing the hardware is not viable, because these are HARDWARE bugs. Version 5 avoids this issue because it does not hard reset your data like all previous versions of ppc. However the hard ware issue is still there it just doesnt effect you. But if you upgrade your rom be carefull because you are trading the bugs you know for the ones you don't know...lol
thanks for advice ........

If it's needing a soft reset after it restarts, that sounds like the battery is loosing it's connection to the phone.
Check the contacts and the battery. Also make sure the contacts are sticking out and making good contact.
Worst case, the battery connector is breaking loose from the mainboard.
Best case, the battery is just not making very good contact to the phone.
and sure to check the condition of your battery.
some substandard/used/aged batteries fluctuates, from 100% to 70% or maybe even lower, that's what i've experienced when i bought my first "Xth" hand BA.. ahaha... i dont know how many times it passed hands.
Cool thanks,
well after having this problem for couple of months I finally took the battery out juggaled it around cleaned the contacts with my finger and not for 3 days already i experience no restarts

If u tries to take off your battery when your device if on.. then u put it again n press the "power" button.. you will see that the radio is "0"/"Zero"..
which means even your device can boot into the today screen it will not receive any Phone Signal.. then after u do a soft reset the radio will appear again..
which means the "signal loss" or problem is caused by the phone's power lost beacuse of the battery malfunctioning..!!
u done a good joob throwing out your battery.. I've battery problem too, but it's more annoying beacuse it cuse my device reset too.. this is realt bad!!
Try tightening up the screws
Try tightening up the screws behind the battery. I had same problem and now its fixed.
I have P3300 with meschle's 4.02 Vanilla ROM. One One, Quicken, TomTom and Stowaway drivers. 8GB Sandisk SDHC. Nothing else. I have A LOT of e-mails and contacts and music.
It has been working pretty good for me, but lately the Artemis hangs WAY too often. I tried to see any pattern, but it seams that it does it totally random. Sometimes it just hangs on the screen, sometimes the screen goes off. Sometimes the soft reset works, sometimes I have to remove the battery and restarts. I think that I have tried everything, but cannot find a problem. I made sure that the card, SIM and battery are all seated and cleaned contacts.
I used to use Battery Status 0.05 and ran at 247, but lately I removed it (and fresh installed ROM) and still hangs. It is my primary phone, so I need to fix it, because it hangs often on my belt and I have no idea that the phone is not working. Help!!!
Even if you clean the battery contact & other visible contacts, there are some wires inside, which need to be cleaned. It may happen if the contacts inside the phone is not cleaned. You can give it to repair shop and clean all contacts inside the phone with electronic device cleaning solution. Internal battery contact, display to mainboard contact is most critical contacts need to be clean.

Hmmmm, I guess you are right. It is just the cost I am wondering. I am not even sure if there is a place who would take it apart. I am thinking maybe using air to blow it? I can take it apart and blow it with clean air. Gosh, scary idea if something flies away. ;-)
If it is a dirty or corroded contact problem you should be able to generate the fault at will by shaking tapping or rattling your phone. Has it been dropped or do you work in a dusty or corrosive environment?

OK, after about a day, it only restarted once (before it used to ten times or so) so it helped. I bought a dust spray for electronics (just clean air) and I will try it maybe again. It seems so far that it is the case.

OK, I blew the air all over it and if there was something it has been gone. It still hangs sometimes. Now about 2-3 times a day. I since re-installed the 4.02 ROM but it still hangs once in a while. The bad thing is that it usually does that in the pocket, so I have no idea that the phone is not working. Any suggestions?
i had the very same problem.. hang on pocket, on the midlle of a call..all random.
tryed to update rom after rom and no go.
Sent it to HTC , they exchanged the board and now it runs fine for weeks.
My guess is that it started to fail after charging the battery with a motorola charger (mini usb 5v type)
but is just a guess

How much did they charge for the motherboard replacement? Isn't it cheaper just to buy another one (since it is an older model I saw them around $300). I thought about getting Kaiser instead. Got one, but to my surprise, it is actually slower than the Artemis (even with HTC ROM or cooked ROMs). Plus it's camera really sucks.
Let me know how much you paid.

Hi mates. I have a weird problem. Just last night I am restoring a Nandroid Backup of VANIR ROM for geehrc, which DONT have a problem with my phone. When suddenly after booting and showing the lockscreen, the phone becomes unresponsive and after a few seconds, turns off. After that, It wont boot, even fastboot or recovery wont show up. Even tried the hard reset combo, but to no avail. Download mode works, but I have not tried to flash KDZ yet. Also when I plug in the charger, LG logo shows up then a blank grayish screen, then a battery icon with charging animation, plus a label that says 0% charging. I leave it for about 4 hours, thinking that the phone might just depleted the battery. But still it wont turn on. When I turn it on while plugged in, the LED blinks in red color. The blinking is continuous. What seems to be the problem? Is it hardware or software issue? Please help me guys! :crying:
Any help mates?
Im really loosing my hope reviving my device. Tried different methods from the web. I just flashed KDZ, but the phone keeps flashing the LG logo when plugged in. When I unplug the charger, and power on the phone, nothing happens! Damn. Can anyone give an insight on what might cause the problem? Thanks in advance!
Sorry to hear about your troubles! Honestly, I have no idea what could have caused this, but if I had the same issue, and nothing worked as you described, I would probably crack the phone open, disconnect the battery and just let it sit for a day or so. Then reconnect it, and try powering up again (might need to charge it first). Who knows whether it helps or not, but it definitely wouldn't hurt, and you don't seem to have a lot of options right now...
It's interesting that the download mode still works. The common wisdom says that you should be good after flashing stock KDZ, but your experience shows otherwise...
i've experienced it before. It happen due to your battery is out of charge. What i do is, i open the case, pullout battery and install back.
After that i charge the phone. And voila...charge is on..and my hp on too. :good:

Thanks for your feedback! It's really weird. I have flashed 3 KDZ's already. From Original F180K to E975. Nothing. Other option I have aside cracking it open is returning it to the seller fro check up. But that's the last resort. I suspect something got "unglued" while I am using it. Since the device got really hot before it happened.

Should you go ahead with it, and in case you've never opened an OG before, just a little advice... It's not difficult, but you need to watch for a couple of things:
1. Make sure you remove the SIM tray BEFORE removing the back cover.
2. Start opening it from the bottom (after removing two screws), and work your way along the sides to the top. When putting it back together, go in reverse (top to bottom).
3. Be careful around the SIM slot and the buttons when prying the cover open -- it's easy to break a thin "bridge" on the side of the cover. Just don't push on those areas.
4. When putting the cover back on, it might be a bit tricky to hold power and volume buttons in position. The easy trick is to use a piece of scotch tape on the outside, so they don't fall in.
Good luck!

I wouldn't suggest actually removing the battery, unless you absolutely have to. It's mounted by a double-sided adhesive tape, so taking it out is a bit tricky. My idea was just to disconnect it. You need to undo two screws that secure the power connector, right below the camera flash. The screws are under the plastic tape, just peel it off. When you remove those screws, carefully pull the connector up. That's it. Check the contacts for any signs of damage or corrosion, and clean up as needed. When reconnecting it, push firmly to make sure it sits properly.

hi, same problem... but i must search at home if i can find a tool to open the screw... i only have - and + in this size and didnt work i miss my phone ((
ok. worked for me fine! Thanks!
now 80% battery instead of 0% very cool
and now i know how it looks into the phone very good working LG...
No more charge stuck on 0% sulation
when I plug in the charger, LG logo shows up then a blank grayish screen, then a battery icon with charging animation, plus a label that says 0% charging. I leave it for about 4 hours, thinking that the phone might just depleted the battery. But still it wont turn on.
SOLUTIONS:
1st take battery out of cell.
Leave in direct sun light for 1 hrs.
Clean battery pin with soft brush.
Charge battry manualy by Desktop charger about 2 to 3 hrs.
Put battery back in phone and start charging.
It will done Insha ALLAH.
Hi all,
I have a general hardware problem with my Samsung Galaxy Tab S4. Maybe someone here has an idea or tip for me.
I still used the factory software without any rooting or unlocking the bootloader. So everything original and up to date.
A few month ago the tablet began to restart in the middle of using it. At the beginning it happened seldom, but then more and more often. Also during the restart new restarts happened more and more often, so that it took several retries, until it started again. Now it is not usable anymore, because it is not running longer than a few seconds before the next restart if it happens to boot completely at all.
I was able to make a factory reset but this didn’t solve the problem.
My first theory is, that this could be a problem with the battery, that it is slowly dying and had more and more problems to hold the voltage. But the problem also exists when the power supply is connected. So I am not sure if this rules out the possibility, that this could be cause by the battery? Does somebody know how this is internally wired, if a broken battery could still have a negative effect when the power supply is connected?
Do you have other ideas/advices, what could be the problem or would could be helpful to do?
Thanks in advance for any help.
Best
The USB power input can't sink enough current to boot it or even run it without the battery acting as a reserve during peak usage spikes.
Replace the battery and go from there.
Thanks, then I will try this.

Hi Vertex, have you tried this already? I have pretty much the same problem and the battery was also my first intuition, but I don't know if buying a new one is worth it. Thanks!
Hi,
unfortunately I didn't had time to do it yet. I want to change the battery myself and for that I will need time and somebody to borrow me a hot air gun, because everything is glued together.
I will report, when I have done it but it will be at least a few weeks.
Alright, so I'll probably try it sooner, I'll update after replacing the battery. Also, if you haven't tried it yet, you might want to try just disconnecting the battery from the motherboard and connecting again after like 20s, I've read that it sometimes resolves this problem, but it didn't work for me. Fortunately removing the back lid of tab s4 is pretty easy, I used hairdryer, so with heatgun it should be even easier.
Thanks for the tips. I am currently on vacation but when I am back I will also try with a hairdryer.
Any additional tips for removing the back lid to somebody doing it the first time beyond what you can see in the youtube videos? How do you glue it back together?
Hi, sorry for the late reply.
I have eventually replaced the battery, and nothing changed unfortunately… I did a factory reset, etc. However I also had an issue that you didn't describe in your original post, which is that USB connection is not working, it only charges the battery, when connected to the PC while booted it's just not visible at all (tried with several cables, two computers, on windows and linux), when in download mode it kind of shows up, but it's not recognized and no drivers or any solution that I've found are working, so I don't know if it's still hardware problem something with the USB related parts or something in the system on lower level. Well, I'll be trying.
About the back lid. Beyond YT videos only thing that comes to my mind is patience. About the glue, you have few options and it depends a bit on how removing the cover goes. 1) glue stays in the more or less same condition as before removing the cover - that's how it went for me - in that case you can just reuse it, just by closing the cover and pressing it down for some time, it's probably not as strong as new but for me it worked just fine, especially if you use a book cover for the tablet there won't be a problem.
But if the glue came off, wrinkled a lot, or just doesn't stick anymore, 2) you can either use a special epoxide glue often with signature like T-7000 or T-800 but if you just look for a glue for smarphones you'll easily find it. Or 3) Buy a special sticker for this exact device which has a specific shape, it's pretty much the same thing as is used by manufacturer.
