kaiser not booting - says battery empty while it isn't

Hello good people,
I've been searching the forums but i don't seem to be able to find a solution for my dead kaiser.
I'll explain the problem:
When i push the power button on my Kaiser, it start's booting the first part, displaying the "smart mobility" slogan by HTC, after a few seconds, some data appears in red, in the right lower corner of the screen, this is what is says:
R 1.27.12.11
G 22.45.88.07H
D 1.56.00.00
After displaying this for a while (about 1 min.) it goes to the Windows Mobile Splash Screen.
After displaying this for a few seconds (5 to 10 secs) it makes the "empty battery" sound and shuts down.
Can someone help me ?
*** And NO, the battery is NOT empty ... i've charged it over night, and the power light was green. ***
I've tried booting with and without SIM and MicroSD cards ... makes no difference.

Will it boot with the phone plugged in to power?
Bill

Yeah, try booting with the charger on. Chances are that your battery' life is out..
Reagdrs,
Carty..

I have had the same thing and wondered if it was the battery... except that sometimes it will stay on for about 2 minutes, sometimes half an hour... but most of the time as soon as it goes to the Today screen, I get the battery dead sound and then it turns off. I am going to try to use another battery to see if that makes a difference.

it's not the battery
I've tried with the power cord on the phone, it does 2 things:
1. The same thing as i said before
2. Doesn't boot at all, it halts on the screen where the red data shows up and stays there until you take the power cord off and the battery out.
It does one of these things, randomly.
I've also tried with another battery from my friends kaiser which works perfectly.
So i guess it's not the battery, anyone another idea what it could be?
Might be something wrong with the firmware or anything? problem is, i can't flash it if it doesn't boot can i ??

any ideas ?
Today i managed to get my hands on a brand new kaiser battery, my uncle has a brand new kaiser and i borrowed his battery.
His battery was full, i put it in my kaiser and tried booting, same problem as above.
I've tried with the power cord plugged into the phone, the charging led went on, and i tried booting, same as above.
Later i've tried with the USB cable connected to the phone and the computer, still the same.
I've also tried soft&hard resetting with the new battery, no succes.
So therefore, i believe it's not a battery or a power problem, it must be firmware corrupted or something of the hardware broke ?
Does anyone has any idea how i can try to re-flash this thing ? to find out if that might be the problem ?

It's not the battery. Could be a bad flash or something. Try to reflash it. Yes, it will reflash even though it won't "boot" as you say. Try to reflash and then report back. Remove the memory card for now.
Also, what Rom and SPL are you using?

Ur going to have to force it into the bootloader to flash it, no biggie. Just hold down the power and camera buttons, and hold the soft reset button with the stylus, untill you get the tri color boot screen. Then flash away! I would flash a stock rom until u can tell weather your problem is hardware related or not. If hardware related keep the stock rom and spl, and try to warrenty return it.

O.k., this just happened to my Brand New kaiser last night too, WTF! Was running fine when the low battery icon came up with half battery life n shut down, now it wont start up at home screen for more than 3 secs before it shuts down and says the battery is dead even while its plugged in! There's no way to reflash or hard reset since it doesn't stay on long enough to do so. Just ordered my replacement, but reading different forums, it seems many people have experienced this with Kaiser and most around the same time, again, WTF!!!

Does it power off while beeing in bootloader? You doesnt have to start the device up to get into bootloader you know. Try checking if it shuts down while beeing in bootloader, if its not just reflash. Another thing, what spl and rom are you guys having this problem using?

It's alive!!!
Finally got it to bootloader mode before it dies and reflashed and it seems to be running just fine now. Using spl ver.1 with schaps 4.30 wm 6 (although users running the stock rom had the same experience). Got the "smart chip not provisioned mm 2" message most likely from at&t killing my sim card from a reorder as they did when I Returned the Iphone which is a rediculous policy(policing); having to constantly contact at&t to update to a new sim. Still, it makes me wonder what caused this defunct in the first place, and if it'll happen again tomorrow or the next day. Reflashing and reinstalling cabs is a Real *****, especially for a pda where people use their device for business and gather a collection of missed calls and lost connections when the Os decides to randomly crash. As much as I dig htc's devices, it's kinda strange how HTC, with such a huge marketshare with pda's, is so quiet about updates or firmware fixes. Anyways, long live the only source for htc fixes, XDA!!

Mine is still completely in the state in which i got it.
Just the stock HTC Firmware, rom's and loaders
Okay, a little update.
How the hell can i flash this thing if it keeps on bugging me with the "Wrong vender ID" message when i try to flash it ?
I know, install HardSPL ... but how can i ? without a possibility to connect ActiveSync?, you'll have to start the device for that and run activesync, but i can't because it won't even boot.
Is there any other way of getting this device to allow me to flash without needing to boot it up fully.
I have no problems getting in to the Tri-Color bootloader, but no further.
When updating it gets to 1%, then my PC gives the message: "Wrong vender ID, please use your own device's update utility" and the phone stays at 1% till i rip out the battery.

ok guys I have the same problem with two of my kaiser's
I can power them up but in aproximately 1 minut goes off, no matter if the charger is plugged or not, it doesn't make a difference
I can put the phone in tri-color screen and stays there with no problem
and I can flash them with no problem because they are olipro already
but after flash them with anything still the same problem ???
so if anybody has a clue or maybe a rom to fix this would be great
thanks
best regards

One more thing. I have the same problem but mine when starts flashes Blue LED when was good hasn't. I Started few times and it works for 2-3 weeks and again. Best to do is to not use camera. Every time it happends i ise my camera and battery was middle-low. I think its some problem with camera. Many times it don't want to start up or saids that there is no memory for saving photo. Maybe i should flash rom from wersion without cameras.

im having the same problem, has anyone solved this?

Yeah solve . HTC as a kids toy .
Buy Nokia! Or SonyEricsson.
I won't buy smartphone ever again.

Does not boot to the OS
I have the similar problem...... My kaiser is dead not even booting with battery only (not plugged to the PC or external charger).
However when I plugged it to the power source it boots up and continue to the OS and boom (shuts off) in split of second.
I tried different flash and it propelry boots and got windows up and running when plugged to the PC with the old ATT test ROM which I got from the xda threads.
But with the latest roms it wont boot to the windows , it dies before that.
Anyone having idea what could resolve this.

any update on this? i am having the same problem. i tried a hard reset already with no success it goes to the splash screen and says "the device is clearing the storage. please wait" then pings and turns off
r 1.65.21.18
g 25.88.40.05h
d 3.57.00.00
my phone is completely stock and has never been unlocked or messed with. found an updated at&t rom, i ran it and none of the numbers change in the bootup, then goes to the splash screen and says again "the device is clearinng the storage. please wait" and then pings and turns off.
also i have been searching for the oilpro or jockeyw hard spl files on google and on here but have found nothing, the search function doesnt seem to be able to find much.
any help would be appreciative, thanks in advance

Don't mean to hijack but didn't want to make my own thread when this one was here. I'm not having exactly the same problem as everyone else but I am having a battery issue. It works fine and says it's charging when plugged in but when I unplug it the battery goes down fast (like 1-4 % a minute) and when it hits around 70%, it shuts off. Then whenever I turn it on, it immediately shuts down before the Today screen fully shows (like others are mentioning here). I have to plug it back into the charger to get it to turn on again.
Could this be a bad flash too..? I know I did one of the latest HardSPLs and tonight I just now updated to the latest stock AT&T ROM. But it can't be a flash because the night I got it (bought it used on eBay), I was playing with it not plugged in using Skype and it shut off on me. I didn't think much of it and had always had it plugged in since then.
I'm assuming I simply need a new battery.. I've emailed the original owner and she says she never had any problems with it like this.

I've just started having the same problem as you. Very annoying. Mine phone is a year and a half old now, so i'm assuming the battery is coming to an end.
Charge battery, will last a while, but goes down to around 80-70% and then it says plug power in blah blah blah and dies. Then when you charge it, it stays on one or 2 bars for a bit and then jumps to 100% fully charged.
Saw a procedure to "reset" the battery. Supposedly have to take the battery out for a bit then plug in and charge fully over night with the phone OFF. None of this seemed to work for me... I'm due for an upgrade in January, so is it really worth paying for a new battery... hmmm

See if you can help

Mods,
Please spare, if I missed the thread for the problem I'm mentioning here.
Guys,
My USB or say PC is not recognizing ma phone. Also whenever my phone battery dies out i.e totally drained or phone turned off (say in 24 or 48 hrs), next time I put it on charging & boot it up, it goes into tri color screen & only boots up normally when I attached it to USB cable on pc.
if this problem has already been mentioned, someone please direct me there.
I'd really appreciate that.
Thanks
A fan from India

same here from malaysia!
I cannot charge when the phone is on, boot stuck on tri-color screen if no usb cable plugged, can't flash other rom and can't hard reset by normal method!
mine is w37 what about yours?

I'm sorry I dint recognize W37. What are you referring to ?

[Q] BA not starting after unsuccessful flash

Hello,
I have tried to flash my BA from WM2003SE to WM6.x following the instructions in
http :// forum.xda-developers.com/showpost.php?p=5456317&postcount=6 but it got hung on the very beginning of the flash process. My BA would got frozen in bootloader (USB/SERIAL and 2.06 on screen). As it was late night I decided to continue the next day, leaving the BA off craddle. In the morning, the screen was completely black and off (it had 100% of battery when I flashed it). I put the device into the cradle and plugged USB to my PC (Win XP) but no USB device appeared in the system, the BA screen is still off and black, the top right LED of BA is still on, red color (switches off when BA is off cradle).
I have tried soft reset, hard reset, several times, holded down the buttons for approx. 30sec while reseting, nothing helped. I have tried to charge the device for about three hours on the craddle, tried to reset again, but no success, the device would not come back to life (nor to the bootloader).
anybody has a suggestion?
thanks
Sileng
PS: Futile to say I have been through this forum to search if somebody had a similar problem.

When you the BA let into bootloader will the battery complete empty load it and follow my installation in the PDF's!!! You have Win7 right or Vista so you must replace the standard driver with the driver from PDF!!!!!!!!!!!!!
PS: BA will load battery when LED is Red or Orange!

Hi d-two, thanks for your fast response. I am not sure if I understand it right though. You mean that it is just my batt that is empty, which obstructs the bootloader to star? By now it has been about 4 hours it is being charged (the red LED shining still, not flashing) and so far no way to bring it back to life. Do you think I should charge it for much longer or it is another problem?
thanks a lot, have a nice day
Sileng

Finally got it working after hours of trying. The key was just to keep repeating the flashing process and after several failures it finally worked. Now I have d-two's WM6.5 on my BA working as a charm. Thanks d-two! It is really impressive!

[Q] HTC TYTN II starts but only charges when shut off..HELP

Hi guys..
I have had my Tilt now for about 2months and recently tried downloading a 200Meg file off the web with it. It drained the power even though the charger was plugged in and so I was clever enough to fool around with chargers...Bleh.. Anyway, so what had happened is that after me switching the phone off etc. I tried charging again without downloading and when I plug the charger in, NOTHING happens..the green light flashes like normal, no light changes and no blips or notifications come up or anything. If I switch the phone off and then plug the charger in, the red light appears and stays there (and I presume it charges). So now I can´t find a fix..Seen MANY other threads regarding similar problems but 90% result in getting a replacement from the supplier which is not possible for me since I don't work off contract and neither is the warranty still valid and neither do I live even NEAR a HTC dealer. I've tried soft resets, hard resets, restarting phone with charger and battery in, without battery in etcetc. The battery is fine.
So it seems my last resort would be opening up the phone and looking if by luck I can see or measure something. Any help at all will be greatly appreciated
Brian

I have same problem, My HTC only charge when power off, No active sync... but i could up rom because in bootloader 3.56 only show USB without serieal . Yesterday i uprom ship end restore SPL. Then my HTC Kaiser can't uprom. It only sirieal when conect USB.
I think it cause by software without hardware. So everyone help us...help me too

Yeah, mine doens't get recognised by my computer at all. Which means no backups or syncs somehow I think my friend's broken TYTN II is gonna come in handy...hmm....
And just for more info, I am as I'm speaking, charging my phone (with it being off) and the red light has been on around an hour long.. Gonna see if it goes off or changes.. Will report back once something happens
Brian
Edit: I just switched my phone on (after around 2 hours charging with it being shut down) even though the light was still red, battery is now 100%.. so.. I'm now downloading the next 200meg file and another 39 files to go
Update: Just something weird.. The tilt was charging(in its shut down mode) and then suddenly switched on by itself.............. uhm..yeah.. so once it came on, i looked and everything was still the same.. pulled out the charger, switched off, put charger back in(cause the battery was about 30%) and boom, green light and switches on again bleh.. so now I fiddled with the battery and charger, and got it to charge in its off state again with the red LED.

I thiink, it can "fix in booting safe mode". But I can set it to safe mode
You can try it, follow step in the link, then re tell to me!
every oen, who can help us?!

hey, I took a look there and I tried those things but it didn't work. Apparently there is no "Safe mode" for these phones unless you have a third-party software. So just to confirm, I took a look through the user manual and found nothing, Googled "HTC TyTN II Safe Mode" and found random stuff but not much related besides third-party Apps. So then I just tried randomly fooling around with my TyTN II by holding and pressing random sets of keys while pressing the soft reset button. No luck.

[Q] [PLEASE HELP] HTC One M7 not charging when on.

Device: HTC One (M7) Stock ROM
A few days ago, my never rooted, stock firmware, no unlocked boot loader, no custom ROM, never dropped HTC One (M7)'s battery died. Plugging in the charger had no effect, absolutely NOTHING. Tried 6 different cables and 9 different locations to charge it, nothing. Waited a while, dying in desperation. Then after so much of panic, I plugged it again, and randomly it started charging. But the charging had a loop - showed a bright orange LED with the power symbol on a battery for about 5 seconds, then a dim orange LED with the green battery charging, and a number, for about 10 seconds. The loop kept repeating. Eventually I could turn it on till the (incredibly low capacity) battery could live. So I did about 10 resets to it, and the situation would not improve.
Since my phone just decided to do this to me just before a long journey of mine, I was quite upset, and eventually infuriated to the limits. I decided to take it along and try different things to it - tried, tried, cleaned the ports, searched the net, nothing.
One fine day it decided to break the loop - now it charged, but only when off.
And today again its started the loop.
And here I am, begging for some help. I'm starting to hate this device now. Please help me.. :crying:
P.S. : I played a lot of Clash of Clans on the phone - it heated up a lot. Hope the info helps (Possible corrupted overheating charge instructions of the phone,etc.)

please help i love this phone cant lose this at all

I am having the same exact problem right now. its very annoying. I have to drain the whole battery to charge it again. and its in that loop that you mentioned. plus it does not charge when you put it on charge when its on. it doesnt even have that charging light. it only charges itself if its off and if there is no battery left, i have to put it on charge by draining the whole battery by using apps and stuff and i am so pissed right now i cant find a solution to this. Did you find a solution on how to get this fixed?

I am currently having a similar problem where I can only charge my phone if off. Hopefully someone can help!

I have found a solution to this. I am really happy since i am able to use my phone again.
Let me state what exactly i was going through.
I had to use the phone till it actually turned off completely consuming the whole battery and it was very frustrating because i had to deliberately use the phone till the phone shuts down and charge it. And once it started charging, it has a weird stupid way of charging. It shows that its charging and it goes off, comes back on and shows its charging, then it goes off... When it goes off the red light goes away...then comes back on.
I've read other threads and forums about people having the same issue. Others say they're not even able to connect their phones to the computer. You all should try connecting your phone to a computer and check if its able to transfer data.
If that happens, then you're saved. Because this really worked out for me.
Now, i'm not really sure what kind of bug this is, but here's how you fix this.
If you're able to transfer data to your phone, you must browse your phone on the computer and copy a file (or a couple of files - in my case i transferred a movie folder that had a couple files in it)
And guess what..i put it on charge and started charging like normal oh my god i was happy as hell
Thanks. I hope the same works for you all, people have been saying you have to clean the charging port but not really

I'm not sure how are you NOT able to get it connected to your computer. Since i connected it to the computer, it didn't start charging but it allowed me to transfer files. And so i did. You might wanna change the cable and check if its letting you connect to your PC.
So far its working perfectly alright. I don't have a problem as such. And wait, you could install a file manager and move a couple files around. Maybe delete some files or download some files and try.
I Hope it works for everyone who's getting this problem. I know its not a hardware problem and HTC support sucks BIG time. i don't even have htc headquarters so i couldn't get it replaced, bad. but if your phone is under warranty you must get it replaced :laugh:

Hi! so you are saying that if i move some files from the computer to the phone it might get fixed? Well, i cant plug it to the computer, it just doesnt recognize the phone, if i plug it when the phone is on the pc doesnt show anything and the phone doesnt charge or anything, just like when trying to charge it with the ac charger, if i plug it with to the pc with the phone off then it shows a message that doesnt recognize the device, and the phone doesnt even charge aswell...
Right now the only fix i have found is to solve the problem of having to drain the battery in order to charge the phone, now i fixed it unticking the fastboot option in energy, now i can charge with any % but the phone must be off. Btw it gets a lot of heat while charging it this way... idk if its normal, i heard that because the aliminium case it gets more heat than normal plastic cases.
Thanks for your reply, ill try to connect the phone to the pc a few more times.

Hello guys , , I have the same problem , charging the M7 (On stock rom), I have tried many things ,roms and kernels , currently I managed to make it charge with the screen on with some conditions..
I installed SLIM ROM from their site (4.4.4) . To charge the phone with screen on I have to check "screen on while charging" (because if the screen goes off it stops charging /same thing if somebody is calling me )
To Charge my phone I just need to Reboot normally and charge it ( if you install this rom Activate the sound for the ac plug/unplug so you can know if it is charging well or not )
Eaven if i have to do these things its better then the OFF mode .
Hope It helps .

HTC M7 Only charges when it's off and the laptop can't recognize the device.
Hello, I've had this HTC M7 since last year. It's worked perfectly until a couple days ago.
The phone will not charge when it's on. It only charges when it's off. Also, my laptop won't recognize the device. I've tried with a couple different AC chargers, but no luck.
Sometimes my phone says "CAN'T CHARGE WHILE IN USB HOST MODE," and I don't know how to take it out of USB Host mode? I'm guessing this is a problem with the software. Before this happened the phone worked flawlessly.
Any help, please??!!

Hello, I've had this HTC M7 since last year. It's worked perfectly until a couple days ago.
The phone will not charge when it's on. It only charges when it's off. Also, my laptop won't recognize the device. I've tried with a couple different AC chargers, but no luck.
Sometimes my phone says "CAN'T CHARGE WHILE IN USB HOST MODE," and I don't know how to take it out of USB Host mode? I'm guessing this is a problem with the software. Before this happened the phone worked flawlessly.
Any help, please??!!

It can sometimes be caused by a defective usb port on the phone, does your port looks damaged? Boot your phone in safe mode and check if its doing the same thing.

I've already done that and it doesn't work.
I really don't know what the issue is? I mean this is a perfectly working unlocked HTC M7.
I've turned if off multiple times and even wiped it clean twice. I don't know what else it could be.
I mean it's been working perfectly since I got it.
But as I mentioned earlier it will only charge while the phone is off. And my laptop can't recognized it either.
It only appears and "Unknown Device."
But even when it is off it charges for a bit and then it completely stops.
Then you see the battery logo and then it starts charging again. But it repeat that same process throughout the whole time. So, it can never reach to 100%.
As I've mentioned before I've never really had this problem.
I've been looking for hours on the internet and so far nothing seems to work. There was an app I saw on to access engineer mode or something, but for some reason I can't use that app because it says that I'm missing another application.
Any thoughts??

I have the same problem, it can't charge, PC don't recognize when the phone is on android, but when i boot into recovery everything work fine (charge or data move to PC), so far i could't find any way better.

Hi,
had same problem.
Clearing system cache helped in my case.
Related cause for the trouble seem to be a couple of OTA upgrades I did recently.
(I was on a pretty old version.)
I noticed that there was something wrong while upgrading.
Even though the phone was connected to the charger while the whole upgrade process,
battery level went down...
The following procedure is your own risk!
Be careful not to choose any options that wipe all your data or factory reset your device.
This is how I cleared the system cache :
Boot into recovery (hold both volume-down and power buttons for ~30 seconds until menu shows - )
Press volume-down to choose RECOVERY and press power button.
Be patient ~60 seconds until menu appears.
Choose wipe cache partition and press power button.
Choose reboot system and press power button.
I hope this helps you.
Thanks
