Boot phone when battery is detect (like APCI on PC's) - Android Auto General

Hello!
I have a Android phone (SG S4mini) that i put on my car to work with TorqueOBD2 and GMaps apps.
I'm from Salvador, Bahia, Brasil and here is super very hot place. And so, to avoid start a fire on my veichle I remove the phone baterry, put a Buck Converter (12v for 3.7v) and connect on post ignition key, direct on baterry terminals (soldering)
All works perfect for a long time till now. But my only problem is: i need manually turn on the phone every time I turn on the car.
So, I need a way to automatic turn on my phone on when voltage (or current) is detect on baterry.
Just to be clear, is not boot when charging, because I do not use the charge port. Is BOOT WHEN VOLTAGE/CURRENT IS DETECTED ON BATERRY TERMINALS.
Plz I really need help!

HELP!! PHONE WON'T TURN ON

So I upgraded to the latest mr clean rom and did some tweaks with the registry Wizard. I was playing around with it for a while and turned it off to charge overnight. I wake up and try and turn it on and nothing. I've tried soft reset, and hard reset and it doesn't turn on or do anything. When I plug in my charger the light on my phone doesn't even come on. PLEASE HELP. WHAT CAN I DO!!!.

It seems that you bricked you phone mate. I think that you installed MrClean rom in a G4 phone so you irrimediably f*cked up the bootloader (IPL and SPL). Many users have reported that their phones were able to boot (and behaved normally) immediatly after the flashing but were dead after they turned them off for the first time, this is what happened to you.
Only thing you can try is going to bootloader mode (but i think it won't work since you messed the bootloader) and then flash a new rom. To do this, press and keep pressed both the keys on the right side and then insert a pin in the reset hole briefly. If the phone goes to the tri-colors screen then you're safe, if not continue reading.
If your warranty perior is not yet over then you can have a new phone for free (DON'T tell them that you flashed an experimental rom!!! Tell only that it went off suddenly or that you were installing an official rom!).
Service centre can repair your device (i suppose they've some method to reflash the bootloader) but i don't know how much they'll ask you.
Try asking other users on this forum. Sorry!

...did you ry to recharge it with the ----ORIGINAL 1A CHARGER----? looks stupid, but i resuscitated mine just before throwing it in the bin. if it works, i will explain you the rest....
yup, I tried charging it with the home charger and still nothing. My battery reads at 3v and it's supposed to be 3.8 so it's not out of juice, but maybe it's just dead?
...you can try with just a normal 9 VDC battery, in order to boost up the voltage, to connect it for a few seconds to the ppc battery till you reach the 3.8 VDC and see if it's working...
Ok, i did that...and amazingly it turned on so I pluged it into the charger right away. Windows booted and about 20sec later the device turned off and won't charge again. So i tried again and the same thing happened. Do I need a new battery? TIA

This is waht you need:
http://www.thetravelinsider.info/phones/cellphonerecharger.htm
This charger is somehow wired weird... it charges the battery AND feeds juice to the phone at the same time (believe it or not, regular chargers and USB cables do not engage until the OS is loaded), allowing you to turn the phone on and in a few minutes plug it into the regular charger to continue charging. Just make sure you get the RAZR tip.
It has saved my ass more than once.
I fixed it , What I did was zap the battery with a 9v battery in 3 sec intervals, I did this about 5 times, then I pluged my phone into the charger and turned it on, the 9v gave it enough juice to boot up and the usb took over from there. So to everyone out there who is having this same problem, try this but don't over zap, check your battery with a multimeter.
im having the same problem----my MDA went dead last night because i forgot to charge the battery and then i went to plug it in the charger but the phone doesnt turn on no more...the light doesnt turn on like if it would be charging and i left it overnight and it still doesnt work..... do yall think that its the battery or is the phone just messed up and cant use it nomore????
Last time I had my battery completely drained, it wouldn't charge from laptop via USB. I read something about how the device's "smart-charging" function itself needs a bit of power to start-up...
but anyways, I couldn't charge the battery through the phone (software charging) - what I had to do was to take a USB cable, cut out one end, identify the +/- (red/black) wires, and charge them directly to the battery's two poles (metal plates). It took about 10-20 seconds of charging until I had enough power in the battery to place it back in the phone, start WM5 and charge it thru the phone.
It would have been much easier if you have a battery charger.
I had my phone connected to the computer through the usb cable, and I just left it connected for a week and it was completely dead and could not be turned on. I don't know how it drained the battery (probally by leaving the wifi on, but the computer was in use all the time). Anyway, thanks to this thread, I used the ac charger and it turned on.

thanks for infos
I'm going to give this a go; a Crossbow ROM flash went horribly wrong last night and in my attempts to repair it (I also must have flashed at least 9 times) the phone went dead. It won't charge either, but battery voltage is 3.7 volts, and I'm sat here wishing it was 3
Will get back to you all!
To update: no... it didn't work! I hooked the battery up to a computer power supply (nearest thing to hand) on 5v and 12v and the voltage increased to about 3.81V... I guess the battery is not the problem with my phone, though the symptoms were the same :-(
Any buttons I can press (i.e. like the voice command button for bootloader) to wake the damned thing up? It's probably fried.

My phone has a hardware problem with the on / off button (doesn´t work at all), at the beggining I thought it was a software problem and I tried all sort of tricks, then I gave up and recognized that was a hardware issue and I found 2 ways to turn the phone on 1) When is totally off (This happens when I have to remove the battery to change SIM card) I connect to the USB cable to my PC or to the car or wall charger and I make a soft reset. 2) When I see the phone signal led blinking I remove the memory card and wakes the phone up (not a good idea since I know that the card is going to get damaged sooner or later).
I just got a G3 wizard from a friend a couple days ago. On Thursday I upgraded it to XDA Mobile 6 and left it on the 2.25.11 (I think) T-Mobile Radio that the T-Mobile 2.26 firmware flash put on it. I used it all day on Friday and then I held the power button and shut the phone completely off for 25 hours, but left it plugged in to a usb to 110V AC adapter that came with my Dell Axim X50V. On Saturday night I went to turn it on and it would not come on no matter what I tried. I found this thread and checked the voltage on the battery directly with a multimeter, 3.13V. I cut the head off a usb cable and then held the black and red wires to the positive and negative terminals on the battery for 2 minutes with the head plugged into a front USB port on my PC. The multimeter then read 3.7V. I put it back into the MDA and it turned on, booted and informed me that the battery was completely drained. I plugged it into the USB to AC charger and it read 10% battery on BatteryStatus. I have left it to charge and it is currently at 60%.
I guess the lesson here is to not totally shut the phone off and let it sit, or the battery won't charge, even plugged into my charger. I guess the OS needs to be running in suspend mode for the charging circuit to run. I know I won't turn it all the way off ever again unless I have my little plug thing and my laptop with me.
(old) Nokia phones have a state called "Acting dead" (from service manuals) which takes place when phone is turned off and battery inserted. It means that the energy is flowing around the board so that the responsible hardware keeps waiting for a 'HIGH' signal ordering to turn ON the phone.
When batteries go bellow the 2.x volts they stop being charged by the phones. This is why i protect the battery terminals with tape when the phone is stored for some time and the reason why a lot of people thinks the phones are broken when not used for months. I usually use the 'freezer trick' where i leave the batteries inside the freezer all night and charge them next day.
just 2 cents...
My Wizard XDA got discharged over the weekend and wouldn't start up - after 12 hours on USB it still wouldn't start.
The charge tips saved my bacon - I modified a USB cable as per the instructions above, and used it to charge up the XDA battery - it only needed five seconds and the phone now boots!
Thanks All, great information!
My 2 cents...
If you're going to try the same, connect red usb to the +ve terminal of your battery and black USB to the -ve terminal of the battery. I'd suggest having a voltmeter to hand to check battery and supply voltage.
Disclaimer - the ablve worked for me, but I'm not responsible for anyone damaging themselves, their PC,their phone or anything else by using the above info!
BUMP! thought my phone was dead, hacked a USB cable and i'm back in business!!!!
TYTN II won't turn on
i left it plugged in all day and when i tried to turn it on it didn't respond. i have a second battery that was fully charged and that didn't work either. i tried a hard reset with it unplugged and with it plugged into the charger. nothing works. i'm on the standard at&t rom with lots of programs. i got it unlocked so i can't go to at&t.

Urgent help about the battery

I posted this question before, but no one answered. But this problem drives me crazy!
My Kaiser turned off when the battery was running out.
When I connect wall power to charge it, the orange LED indicates it was charging, but just few seconds later it automatically boot, and the orange LED was off.
The problem is, it can't boot into OS due to low battery(it only shows "Smart Mobility", but can't even enter bootloader mode) And only if it boots into OS successfully, it can be charged.
Anyone met this problem on any other devices before?
How can I stop auto boot when charging?
What can I do?
That must be something specific to the rom on yours... mine does not automatically boot when when power is applied (assuming it is off, not just in sleep mode), and it charges fine when powered off.

I use the ROM from this forum
RUU_Kaiser_HTC_WWE_1.56.405.5_radio_sign_22.45.88.07_1.27.12.11_Ship
What is yours?
I'm just using the stock AT&T Tilt rom.
Here's the fix!
Yes, I've had the same problem a few times on my Vario (Wizard). Very annoying.
Here's what to do:
- Take a mini-usb cable (the one you use for sync and charging from a PC) and cut off the mini-USB connector
- Strip the wires
- Take the battery out of your TyTN
- Carefully connect the ground wire (black) with the ground connector (-) on the battery. Fix it with clear tape.
- Now do the same with the (+) (red wire).
- Attach the USB cable to a running PC and let the battery charge for about an hour. After that, put it back in your phone, you'll be able to boot it up and charge it the regular way.
Yes, it costs you a cable, but it solves the problem.

I think you misunderstood. The problem is that the phone only charges when the OS has loaded completely. So if you really run your battery out completely and there is not enough power in your battery to boot up the phone (read: it turns off again before the boot has completed) you won't be able to charge it the regular way. SOMETIMES a heavier charger (2A) does seem to be able to charge the battery even with the OS shut down, but most of the times it won't work anymore... see below for fix.

Based on this, it sounds like it is starting to charge without the phone booted (orange LED on), but for some reason it then automatically boots up, then crashes because there's not enough power(??)
But if the problem IS that the phone only charges when the OS has loaded, that is also not how my phone operates. In fact, that even goes against the manual, which tells you to plug the phone in (without turning on the phone) and let it charge fully for the initial charge before turning on the phone and allowing it to boot.
Sorry if I misunderstand, but neither way is how my phone operates... it can charge without the OS loaded, and the phone does not automatically boot once power is applied.
Not sure I fully understand what's going on here but, I am wondering if the power on/off button is stuck in (i.e the micro-switch is clicked in and not releasing). I cannot think of any other reason the device would turn on when connecting the charger if the device is powered completely off. ( Except perhaps shorted connections in the Usb port)
Mike
To SteRo:
Thx a lot for the solution, I tried, but still doesn't work.(I charge it more than 2 hours, and still can't boot into OS)
To mikechannon:
yes, it happened. :-( the power on/off button is NOT stucked. And the device is powered off completely.
To All:
Thx for your reply. What I mean is almost what dscline said:
It starts to charge without the phone booted (orange LED on), but for some reason it then automatically boots up(around 15 sec after I plugin power), meanwhile orange LED is off. But it can't load into OS, just re-boot again and again because there's no enough battery. That makes it's impossible to charge, 'coz it's only charged when the OS has loaded completely.
Anyway, I called customer service to ask them replace the battery. I may try to use different ROM and see what will happen. I'll post the result here.
It's also possible that it has nothing to do with the battery or charging at all. I just checked mine, and the charging indicator is lit with the unit off, but it does go out for a bit during the boot processes, then comes back on again. So what you're seeing with the charging light is normal. It may simply be that there's something corrupted, or some other failure with the device, that is causing it to not boot properly, and get stuck in a reboot loop. If so, it will probably do the same thing with a completely charged battery. You may have just been assuming that it was related to a low charge.
That's what I'm worry about,, Coz I can't boot it by SteRo's solution.
okay... they say trouble comes in three's...
Yesterday I flew to Asia, 20-hours with a full charge. No suprises during the trip. Checked email from Narita during the layover, no prob. But after I arrived in Taipei I received the low battery warning. Plugged in my usb-to-usb (notebook to kaiser) cable and "no charge light"!
This morning I plugged it into a ac battery charger and waited for >10 minutes, still no charge light.
Now, at the risk of a battery, I'm attempting to charge the battery removed from the kaiser using the previous mentioned method. In an hour I'll test it.
This afternoon I'll pick up a new battery charger and spare battery.
In 14-months with my trusty TyTN (cht9000) I never once had a problem like this... I'm a little bummed right now...
[update]
okay -- battery is okay and can be charged externally (using the two wire method or an external battery charger). BUT... the device still won't take a charge using either a direct AC adapter or a USB cord. This was also retested after performing a hard-reset. Not a good sign folks.
The charger works (connected to a Trinity), so it's not the problem. They battery works (charged to 45% after 45-minutes connected to an external battery charger). The HTC OS after a clean hard-reset used to work but now doesn't, so it's unlikely it's software related.
I've made no other modifications to the bootloader or SSPL... everything is original stock. Wish I had my TyTN with me right about now...
Sounds like something I had on my previous TyTN:
The power connector was a bit flaky on my charger at home. So when I'd hookup the powerlead it would charge to 10 secs or so and then no longer charge. I had to put some pressure on the connector to have it continue to charge. So I put a ballpen on the powerlead, just under the phone, when charging.
It's a long shot - hope of use. When you've connected the phone to power, and the orange light goes off, try wiggeling the connector a bit - see if that helps.
Hope of use.
Re
OK,
I've got excactly the same problems... I dont want to make you illusions, but you cant solve it and you need to send it back for repair. Your usb connecter on your tytn is broken...
first i will tell my story...
My tytn did excactly the same, shows the led, powers on automatically (normally it don't do that, so it;s not a rom issue) and then powered down in the smart mobility screen. I tried 4 chargers, and 2 battery's. with a full battery it will power on and load windows, but unable to charge. with the empty battery it will power down in the smart mobility screen. soft reset, hard reset, it won't work.
You can check if it's the same problem, by attaching it to your usb on your computer and call up the bootscreen by pressing the camera button and stick your stylus in the soft reset hole. If it comes up with serial instead of usb, then your device usb connector is broken.
BUT, you can charge your battery in a very strange way i figured out. since i am on a buisness trip i need my phone and don't send it back!!!!!
ok, this is what you have to do, plug in the powercable, call the hard reset screen BUT DON'T APPLY!!!! you will notice it will not power down, so just leave it on this screen for a night with the cable connected. you don't see the charging light, but actually it is charging. for me this temporarely solution works fine... but when i'm back in about seven weeks i send it in for repair.
Hope this will help you!
Swiftgs:
Many thanks for your insight -- you are correct, in bootloader mode the Serial shows instead of USB. I just purchased a spare battery (1100mAh, made in Taiwan) and battery charger for US$17. It'll get me through my business trip, but this is disappointing. As I mentioned in my earlier post, I used a TyTN for 14-months (July 2006 to Sept 2007) as my primary phone, recharging it daily via the USB connector and on a desk charger in my office. I can only conclude that if the USB is physically damaged (not evident visually), then it is not as robust as the USB port used in the original TyTN. The strangest part of all is it worked perfectly until the battery level fell below 10%...
FWIW: I purchased the phone through R&D Marketing. Ron Webber quickly responded to my note and gave me a contact at HTC America. I'll follow-up
after I return and report my experience.
Cheers
well, thanks for all of your replies/infomation.
I tried evey possible methods mentioned above, unfortunatelly none of them works :-(
and the most depressed thing is I filnally get a new battery, but it still doesn't work!
So I sent it back to repair, cross figure...
It works
I would like to thanx 2 SteRo for his advice. I am using Qtek 9000 and had the same problem. Battery was empty, and I tried many times to turn on my PPC, but without success. All the time when red light appeared after 10-15 sec display become black and tried to restart from boot again, and it's happened many times. Finally I thought that I just can trow my Qtek, but seeing your recommendation decided to try. I took USB cable cut it and strap the wires. Connecting red on (+) and black on (-) after 1 hour charging I was able to start my PPC, to recharge battery by 100% and it is working now OK. I must check duration of the battery tomorrow, because reason why I discharged battery was automatic turn off of my PPC when it was on around 45-50% battery capacity. Tomorrow I will check how it's working when I recharge battery again.
Dear SteRo you are the king.

Another brick in the Wall... :-( Needing help with Wizard

Shortly: I flashed a new rom (not so new... Mameli 2.0 with WM6.1) and the upgrade process stuck on 99%, computer saying "All Done"
No so... trying to reboot the Wizard gets up the bootloader screen... no problem, will you say BUT... I was in a hurry so I leave the USB cable connected and go away for a few hours (I suppose the USB cable may keep powered the device but now I guess no... )
So, when I came back, the Wizard was turned off.
First try was soft resetting the device with no success: screen remains black.
Then I try to connect the power supply and nothing happened...
Then I pull off the battery and keep it off for a few seconds... I was googling with the device in this state when the bootloader screen pops up for not more then 15 seconds then blank again...
No way to enter bootloader mode or to hard reset the device...
I suppose the battery goes almost flat... and I've not a cradle... is there any way to charge the battery? or a way to build up a cradle-substitute?
May be the issue due to battery flat?
Thanks, Pino
Try plugging in to the original charger, not a USB cable, with the power off.
After about a minute you should see the orange LED turn on.
At least that has worked for me when my battery has been dead.
Nothing... It was already done... I suppose the charging doesn't happen if the OS didn't load... even if I read about some stating that if the charger supplies 1.0A the charge happens...
Now I'm trying to charge the battery with "alternatives" methods...
Thank you for your interest
and so?!?!?
So much lurking... noone writing?
Ideas welcome....
I've done something similar to this too, i.e., where battery gets so low that phone cannot start charging cycle.
Here is what I have done. Take note on the battery of the positive and negative terminals (clearly marked on battery). Use a regular 9V battery and some wire (or 9V connector) and connect the 9V to the phone battery (+ to + and - to -). Allow the phone battery to recharge some from the 9V. I suggest connecting for about 1 minute or so and then disconnecting again for 1 minute or so, and repeat this cycle a dozen times or (or more) using this 50% duty cycle charging. (not sure about charging current, nor heating of battery and don't want to overheat or damage the phone battery).
After giving the phone battery some (re)charging, then try plugging phone in to see if charging cycle comes on. (try first without trying to turn on the phone. If no response then try turning phone on while plugged in to USB). Generally makes no difference whether using USB plugged into computer, original charger or after market, ... phone does not, nor cannot discriminate between different 5V 'USB' sources.
If this doesn't work then the next step is to carefully touch the 9 V to the battery while in the phone and connected to USB (and to play this safe use charger, and not computer USB ... don't want to risk damage to computer). I would only try this if you feel extremely comfortable with electronics and voltages (albeit this is very low voltage) and as a last resort. KEEP IN MIND YOU WILL BE DOING THIS AT YOUR OWN RISK, and I don't want to be blamed for anything that may go wrong with the phone or otherwise by you trying this. This has worked for me on several occassions, but I am an engineer who has experimented with electronic ciruits off and on for 16 + years and so feel comfortable doing stuff like this. (again remember + to + and - to -, battery to battery).
Good Luck
First of all... Thanks for replying...
The problem isn't due to battery too much empty (it's a frequent issue, with mobile phones too...)
I suppose the Wizard needs be correctly initialized to start charging the battery and mine was in bootloader mode.
Sometimes I am able to power up the system for a little while and the bootloader screen appears but the battery doesn't charges so I cannot disconnect the power supply... this is why I suppose I'd get better times if I got a cradle.
Now I'm trying to arrange a flying connection between the battery and my kaiser's desktop charger to give the battery a bit of charge and verify my ipotesys (uh-oh... it's correctly spelled? sorry for my bad english....)
OK, wish me luck
stay tuned...
OK, no more bricked
The issue, as I supposed, was due to a flat battery!!!
I tried unsuccessfully to charge it back using the external charger for my Kaiser, probably the unsuccess was due to difficult to obtain a stable contact between charger pins and battery leads...
After that I remembered I had another battery. It wasn't used for a bit of months (I use the wizard just as backup, when the Kaiser is out of order) but luckily I stored it full charged so the battery was able to make my wizard power up (strange thing, I needed to keep the power button pressed as the device powers down as soon as I release the button!!!)
I tried to update the rom again but it failed at 99% so now I reverted to an old rom but the device is still alive...
Maybe I'll try again the update but not before having fully charged both batteries
See You and thanks to everyone tried to help...

Tablet won't charge when on (android and Windows)

Hi everyone! Today a very strange thing happened... I was using my tablet with Windows, with a usb hub attached to use a simple mouse. This hub has a micro usb output, so that I can charge the tablet while plugging in usb devices (that's exactly the one techtablets uses in one of his videos about this tablet). All of a sudden it stopped charging, so I tried rebooting: NOTHING. Then I switched to Android, but still no luck!
I'm happy I see that it charges if it's completely off, but I don't think it's normal!
What do you suggest me? This tablet is fundamental for me, as I study with it!
Anyone who could kindly help?
Same here and notice this after your post here. Windows notice that i plug in the charger (screen brightness was different with pluged in charger) but doenst charge.
I'm thinking that it might be BIOS related... Unfortunately I can't update it (I have 2.02 version already), or at least sort of reflashing it, cause I don't have a usb keyboard... Can you make a try? Cause it's weird it happens on both Windows and Android! I also noticed that if I have it off, charging, right when I trigger the power button and the teclast logo appears, right before the choice of the OS, it stops charging..
i have same problem, do you resolve it for present? how do you use your tablet?
Mine was a bit temperamental and as described above for the 1st 6 months but now it will not charge even when off unless it is left for days. Then no where near full charge.
I had very similar problem on my old teclast c6j6 tablet a year ago .
It seems my usb connector in tablet was too loose after few months .
I opened and pressed ( squeezed ) usb connector and was work again fine .
For the time being I connect and disconnect usb cable very gentle on all my teclast tablet and is fine .
I have the same problem. The tablet will not charge while powered on and starts charging right away as soon as it powers off. I do not have to wiggle the cable or anything. ON = not charging, OFF = charging. It's very unlikely that this is caused by a bad connector.
Be careful when you use Android. If Android shuts down because the battery is low, the tablet will start as soon as you connect a power cable. The tablet starts up, stops charging because of this, shuts down because the battery is low, starts charging as soon as the tablet is powered down, starts up, stops charging, shuts down, starts charging, starts up, stops charging and s on. Viola: you have a boot loop.
I wrote about it here: http://forum.xda-developers.com/x98-air/help/dead-battery-bootloop-t3243993
There is a fix which requires some soldering. This is a YouTube video which describes the procedure:

Phone Display shows empty battery and wont boot

Hi Guys - after some help if you please! My Z3 C has decided to refuse to power up. Without the charger plugged in nothing happens, even when I use all the usual vol up and power etc.
When I plug the phone into the charger the screen just shows the empty battery screen and turns off/on/off/on etc cycling like that.
Just cant get it to start.
I can manage to get it to reload the software through pc companion and it gives the successful message. But after trying a reboot, nothing happens.
Now because it does the software rebuild, I assume the phones not bricked. So could it just be a goosed battery?
Cheers
Terry
Hello,
I have similar priblem few years ago.
I figured out in this "overdischarged" state when i try to charge, and appear the battery screen, if the battery reach a critical charge level, the phone will try to boot. But its fail, because te voltage still too low, so thats why its reboot. I did this: (i dont take any responsibility)
Put the phone in a plastic bag, hermeticaly close it to minimize the vapor, then put it in the freezer.
Wait.
When its cold, connect to charger, now you able to charge more, before phone is start to boot. Charge it till start to boot, and Turn it off immidiatelly with the little button next to the sim card.
Now, you haveto warm it up, i do it with a hairdryer, use it at least 10 mins, not jost the cover, but the battery must have warm too. 50 celsius is fine.
Now connect the charger, and try to boot. Hopefuly, you can able to boot, and the phone will start charge.
