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.

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.
Ok guys, I bought a Droid 4 with a "battery problem" the battery flex cable was ripped so I tought just a new battery and the phone would be ready to go, without battery I connected the phone to the usb port of my PC and a green led appears, that was good news, a sign of life of the phone.
I received the battery today, i connected it and the problem was worse, I have no video, no sound, neither the led light, the digitizer keys and the keyboard doesnt turn on, I tought the battery came DOA, but when I connected the phone to the PC was recognized by the PC because the Motocast partition appeared, the somehow i just managed to boot on fastboot, and is working too... but, then, what exactly is the problem?
I dont have:
No Lights (led, keyboard, digitizer)
No Screen
No Sound
No vibration
No touch feedback
I have:
Power
Can enter Fastboot
Maybe its bricked and just flashing ICS would resolve the problem?? I have no warranty, so i don't have nothing to lose (only money from the phone and the battery lol), the phone doesn't have water damage, its in excellent condition, the phone doesn't have signal to be opened before, but still is a probability because the battery was originally rippered... and maybe that is a signal that the previous owner was someone like us and the flashed GB when he was on ICS and maybe the bricked the phone? I don't know... I'm going to flash the fastboot ICS to see if maybe can come to life, but i need to work now... maybe later.
UPDATE:
OK, ITS BRICKED, I dont know how, but Its bricked, since i can't see nothing i booted in fastboot and then tried to flash the stock .217 ICS firmware with RSD Lite, but i'm getting errors... and I have low-battery, and tried to flash using The Project's Eternity EPRJ_Fla****RZR_Windows, but still with the low-battery issue, i removed the battery and plugged to a universal charger to gain some charge and try later... maybe I can rescue this phone.
Have you tried using a fastboot cable? If the battery is low and you are using a normal cable, it won't (sometimes) charge and definitely won't let you flash anything in fastboot.
VZW recently sent me a replacement D4 with a very low battery, and when I plugged it in it would not charge (!). Hooked it up with a fastboot cable and it started right now, charged it, and good to go.
The problem is not the battery, I thinked about getting a fastboot cable, but instead of spending $10, y just unplugged the battery and putted on a universal charger, it worked, i entered to fastboot mode, i flashed .217 firmware, and also used the Droid 4 ICS Utility to flash .217 firmware again and WIPE all data. But again i tell that I have NO DISPLAY, NO VIBRATION and NO LIGHTS, the led lights works sometimes, but no display, vibration and keyboard lights is weird, i connect the phone to the PC and can access to MOTOCAST... but why??? maybe I need a HDMI cable to see outside the display, maybe the LCD and digitizer are broken, but no, they are on excellent condition and the ribbon cable between the two bodies are intact... nothing is loose inside.
Hello everyone,
I installed a JB rom a few weeks ago on my TP (can't remember which one)...it worked for a little while, then i wanted to flash something additional and it seems to be bricked ever since and has been laying around...which is why I can't remember what exactly I wanted to flash
Anywho, if i connect it to the PC the notification LED on the home button is blinking..but that's it. no combination of power/voldownup/home button seems to be working and when I try to run webos doctor it doesn't recognise my device.
can anyone please help me?
When you say bricked. Do you mean stuck in a boot loop wouldn't turn on etc.
Have you had it connected to the stock charger or better still on a touchstone and if so for how long.
The more information you can give the better.
No it doesn't turn on at all, screen stays black.
It's been connected to what i think is the stock cable to my pc (there are too many Micro-USB cables laying around here ) for about an hour now and i just put it on the touchstone (LEDs are still flashing)..
Leave on the Touchstone for at least a few hours preferably overnight then hold the power and volume up buttons for at least 30 seconds if nothing happens do the same with power and home buttons and post any progress or lack of, but the first thing is to try and put some charge into it and the best for that imo is the Touchstone.

The stock cable for the touchpad has a silver dot at each end. I have two touchpads ad the connection is very loose and unreliable. It often won't charge. I bought new Micro USB charge/sync cables and charging is no longer an issue.
The USB port on your computer is not powerful enough for anything it trickle charge. You need a stock touchpad charger.
Well i charged on the touchstone and then after a few hours i was able to boot into recovery and flash a new rom problem solved, thanks anyway!
Hello
I've got my Mi 9T Pro since one month.
Since one week, I can't enable MTP USB mode while connecting my phone on the PC.
The phone is charging, but no transfer mode available in the notification panel, tried developer mode, USB debogging, tried multiples cables, same problem. I can't transfer files by cable.
Also, charging is quite erratic, If I move the phone, charging can connect/disconnect.
At first I thought it was hardware issue, a problem on the USB-C connector. This disapoints me because I take care of my phones and I never had a problem like this.
But what just happened make me doubt. My phone was charging normally (it was around 50%) then stopped charging. Tried to plug/unplug, changing the cable, same problem, no charging.
I thought the USB-C connector was dead and that I could never charge the phone again.
But I tried to restart the phone and... it works. Still no MTP mode, but charging is working, while 10 minutes ago it was not working at all.
Do you think it could be a software issue ? Or battery issue ? Does anyone had the same problem ?
Thanks.
Yes
Did it solve ? And if yes , how did you managed to fix it ?
Because i m facing same problem as yours? Pls help me
Same. Weird issue. I guess the cable has become faulty. Or there's lint collected inside the charging port.
Have you fixed this issue? I have the exact same issue you described, I own a Mi 9T, installed Havoc OS

It is clearly USB-C issue (hardware).
That's mainly caused by instable current ,bad powerbanks, Powerful/weak chargers (not the original one) , or damaged/low quality cables, and also use/gaming while charging (the heat causes damage).
Use High quality cable , Original Adapter , you will never have this problem.
bottomline , you need to get your USB-C cleaned or fixed (in case of damage).
Hi,
I've been having issues with my unit (6/128gb) for the past month, and for the life of me I cannot figure it out. My phone reboots multiple times when fast/turbo charging, sometimes even when I'm charging it with my PC. I did not damage my USB port nor the original cable.
I've swapped multiple ROMs, AOSP and MUIU, still no changes. Different charging bricks, and cables (Samsung original and few cheaper) - no changes.
What I have noticed is that if I keep the display on, it will not reboot. I've even made a python script to write down the battery temperature each minute (thought there might be a spike), and if the script is running, then the phone will not reboot, even pushing the maximum 33W and display off.
Also, my PC does not recognize the phone, displays an error, and the phone reboots even if I try charging it while off and while in fastboot.
Does anybody have any suggestions? I thought even swapping the USB board, but I do not think it is the culprit.
