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.

Thanks
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.

That's not how I read the original post:

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)

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.
Hi,
After many years of enjoying this magnificent phone the disaster came.
The phone discharged overnight and switched off. In the morning I had to send some texts, so plugged the wall charger into USB socked (a weak one ~500mA), after few moments a charging icon appeared and stated that battery has 1%. Ok, I really had to send those messages: I've pressed the power button and phone started to boot.
Sony logo: OK, purple wave, OK...
After 10-20 seconds it suddenly switched of, red LED started to blink.
I thought: OK, system startup needs a lot of power, maybe a charger is too week to keep up.
So I left phone for few more minutes to charge, but without success.
That was the last time I saw screen was on.
Phone is a C6903, running on a stock, rooted 14.6.A.1.236 with the recent XZRecovery.
Bootloader has been unlocked.
For the moment I've tried everything but opening back and doing the testport-trick.
When I connect the power only red led blinks (I left the phone charging overnight, no change).
When I try to enter flash mode: nothing happens but red blinking light.
When I try to start phone nothing happens at all.
But there is still hope:
I connected the phone to 2A charger using a magnetic cable.
Then I've connected normal USB cable to my PC, strange thing started to happen:
When I pressed volume Up (even after few minutes of connecting power+usb) the phone suddenly jumped to fastboot mode (blue led, it was discovered by PC, fastboot terminal was functional)
When I press power button, phone vibrates for a second, then the led pattern changes to: 1s red followed by 0.1s green, then long red, then it repeats...
I'm still unable to enter any recovery nor flashmode...
I'd really appreciate any help, have you got any ideas left how can I revive my phone?

Hi, this just happened to me, my phone has been dead for over 4 weeks with just the red led blinking. i tried the test point thing with no success at that point I gave up but last week i decided to get a new genuine battery and it worked it booted up. Your battery is just completely dead thats why it won't boot up!

Thanks for the info! I've ordered a replacement battery already.
I'll open my phone today and measure all voltages. I'll keep you updated.
Good luck

Yup! That was it (at least I think so, I don't have new battery yet)
The Al part of positive battery terminal was broken: I have no idea why, maybe because of age, oxidation and high currents that were drained from this LiPo cell...
Anyway I've managed to temporarily join two broken Al parts, kernel and recovery booted successfully.
Now I need to wait for a replacement battery.
Phone is alive again, thanks tilakpatel for help!
But the magnetic cable trick might be useful in other hardbrick cases: just connect magnetic charger, connect normal USB cable to PC and hold volUp. Phone should be able to enter fastboot even with completely drained battery...

Essentially, been using LineageOS ROMs since I got this phone two years ago, everything had been working just fine and generally happy with this phone.
The story starts that I had just charged my phone overnight, had woken up, unplugged it and was looking at my notifications.
Opened a WhatsApp notification, instantly the launcher seemed to crash and was unresponsive, although the notification tray was functioning still. Tried to turn off the phone via the power menu, device did not shutdown. Forced power off on the phone, phone turned off.
Immediately I was unable to turn the phone back on. Tried recovery, fastboot boot methods and the device would not turn on at all. The screen is black and the device not responding to anything power related button combinations. When I plug the device into power, no charging light appears on the phone, the screen doesn't turn on at all with the typical charging animation when it's in the off state. When I plug the device into my Ubuntu machine, no USB device is detected by the kernel - as though nothing is plugged in at all. When I plugged it into my battery pack however, it did appear that it detected a device and flashed it's LED as though it was charging a device that was plugged into it.
I had not wet the device, or *recently* dropped it. It lives in a pretty reasonable case and has stood the couple years of my use with essentially no scratches other than some very minor abrasions on the screen.
I have a little phone electronics tool kit and a hair dryer, and as the battery was fully charged before this had occurred, I decided to pull the phone apart and disconnect the battery from the mainboard behind the NFC assembly. I also tried disconnecting the power charging circuitry in case something was shorting in that area - still nothing. Left the device with the battery unplugged from the mainboard for 5 days, and just tried it again - still no dice.
I'm just wondering if anyone knows what the cause might be. At this stage, I'm suspecting a mainboard failure, in which case data recovery seems unlikely. I have had over two years out of the device, it's far from the end of the world. I'm reluctant to spend any money trying to repair it particularly if it's the mainboard, I'll lose my data anyway. If I were able to retrieve the data from the device that would be of some benefit to me, about a weeks worth of photos and some chat history with my GF; so some questions I have:
1. Should I be able to power on the device with a USB C cable plugged in but the battery unplugged?
2. Apart from what happened above, does anyone have any suggestions about the cause remembering that it doesn't turn on into any boot mode at all?
Do you have any windows device?

No I don't sorry. I also bought a new battery for the Mi 8, the device still didn't turn on or charge. I think I can safely say the phone is cactus.

Hi, I have the same problem, but with the latest Xiaomi eu stable. I just put my phone in my pocket after a full charge and when pulled it out just a black screen and now it's exactly like yours
Did you solved the problem?
Hi I have an issue with Redmi 9T. It is hard to complexly describe issue, but I will try. Suddenly phone stopped taking charge and turned off. Then it sometines take charge and sometimes not. I have completely cleaned charging port, took phone apart and changed battery. As soon as phone starts it works absolutely fine (charges everytime cabel is plugged in, power button works correctly etc.) until I turn it off for some time. Then issue appear again. I am only able to get is started, when taken apart and disconnect battery and then connect again. In this case it is also weird, because it needst phone to be on charger for some little time, then it lets me turn on phone. It looks like phone "thinks" it is completely discharded, but when suddenly works and it boots into phone, battery has normal charge. When phone is in state, that it does not respond to anything, when charger is plugged in, it takes 0.05A and do nothing. I have quite enough experience, but I have never come across issue like this. Do you have any ideas, how to solve this? Or any hint what should I try?
The same started happening to mine not long ago. I don't know the reason nor the fix. I got my battery changed but didn't seem to do much as it started happening again some weeks after.
I have exactly the same problem. Couldn't it be software?
