Is my Kaiser dead?

Hi, recently my extUSB broke down, so I was unable to coonect anything. My friend changed the connector in proffesional way with IR gun. But now Kaiser won´t even boot up, no vibration on startup, only green LED is lit up.
I bought D2, but I am curious if there is any way to fix it.
Thanks in advance

What does your friend say?
What happens if, while holding down the camera button (on the same side as the power button but further down), you press the power button to power it on - do you get a stripy screen? If you do, you can poke the stylus into the reset hole to reset the device out of the bootloader screen. What did the friend have to say about it - personally I'd much rather have a TyTN II which boots and works fine except for a broken USB port (I presume it was working fine before the 'repair'), than one with a shiny new port that won't work at all.

Nothing happens it looks like it is absoluttely dead.
The USB port was faulty, that was reason, why I let it change.
Well, it is strange, but actually I am very satisfied with with D2, even more than with Kaiser...

Well I suppose you could always get an expert to look at it but if its motherboard is damaged (or there's other hardware damage), it may be more expensive to repair than it's worth. You could see what your local HTC people have to say about it.

Or you could sell it in the market section, plenty of people that would like to get a crack at fixing it or use it for parts.

Hi, I just encountered the very same issue. I know I'm ressurecting a very old thread, but I rather do this than creating a new one
I flashed my Kaiser with Android about two months back. Everything was quite stable, no hardware issues. Suddenly, it won't turn on.
When I plug a charger in the extUSB, the orange LED won't show up. And if I try to turn on the phone, the green LED shows up and stays solid. However, the short familiar vibration isn't there and also the screen remains black. Nothing was wrong with the USB port. I tried multiple chargers...

Have you tried to reflash or hard reset?. Also maybe your battery is gone..try another one.

Some things to try

I realise you cant flash if it's not booting but if your battery has sufficient charge remaining (won't work if it's flat) it'd be worth trying a hard reset using the D pad key + stylus in the hole method (can be done at switch on time without needing a full boot).

How do you know that a fault hasn't now developed with it - I wouldn't rule that out at this stage. Have you tried a known good battery that is fully charged in the phone also is it the original charger you are trying (not all chargers with the same plug are compatible)? Are you able to get the bootloader screen to show and if so, what does it display?

No bootloader, no nothing - just black screen (there's not even a hint of backlight). I'll try a different battery today.
I tried using my old AC charger, my colleague's AC charger (for TouchPRO2), USB cable... the orange LED still doesn't come up.
What's the hardreset using Dpad key? I tried holding the power button + camera and also holding the two "context" keys (above explorer and messages buttons) and touching the reset button with the stylus.
I'll see whether a different battery will do the trick.
Thanks a lot for all your suggestions, guys! Much appreciated!

The context key one you mentioned is what I refer to as a D Pad hard reset. The one where you press the power button while already holding down the camera button is how to get into the boot loader - it's all explained in the Kaiser wiki. Sounds like another battery is definitely worth a shot - especially if you only have one (I have 3 for my Kaiser and on some days with heavy GPS use, I need all of them). What happened between it working and not working - what were you installing or doing with it?

I tried another (fully charged) battery from my gf's Kaiser today. No change. When I press the power button, the green LED shows up and stays solid (no blinking/flashing). Screen is black, no short vibration. I tried all sorts of hardresets and also tried to get into the bootloader. No luck.
Also, I took my multimeter and measured voltages on the charger, the battery and the pins in the phone where battery resides. Everything seemed to give a correct voltage. So it's really not a power issue
Thanks for all your help, but I'm afraid I have a total brick in my hand.

My Kaiser
Hi I have a HTC Kaiser I bought the first week it came out and it was f=ine for quite a while but 6 months ago it stopped working. It'll go to bootloader but won't flash. When trying to turn it on it'll go and just get stuck on the splash screen. I figured it was a battery because I'm very hard on my phones but I just got a replacement battery last week and all 3 of my batteries act the same way. I may have been trying to flsh went it went down it was a few months ago so I can't remember.
--- Other things to note
My Kaiser got wet and I had to have the usb port replaced and the dpad replaced. The usb acts fine but the middle dpad button does not work
The charging light will stay orange or green after I unplug the charger
After reading for the last week I think its either bricked or maybe has a bad hardspl on it?!?
Thanks in Advance for any help you guys may give.

Time for it to visit the same phone repair shop (or HTC) again for an assesment/possible repair if economically viable. If it's only recently got wet, you may be able to catch it before corrosion sets in and causes any damage but if it's not dryed out/cleaned quickly, the damage (from the resulting corrosion) will eventually show up (possibly in all the ways you've described).

[Q] Xperia Z Wont turn un unless usb connected

Hello
Recently i've bought an broken screen Xperia Z, for repair it (i got it like $300 bucks cheaper) and i was ready to buy the screen, but i battery was drained and i could not test it right, when i connected to the charger, it started red light, vibrate, then 3 continuous vibes, read on the internet, OK BATTERY DRAINED, i left it charge THE WHOLE NIGHT, and when i woke up in the morning it was orange (charging), later in the day it was green (charged) but when i disconnect it, it wont turn on anyways, when i connect it to a pc, it goes blue light (wich later i read it was fastboot mode). i read for making a repair with PCC, but it didnt fixed it, then i flashed it with Flashtool, with the latest software (wich had the Sudden death issue fixed) no luck. it wont boot. for it to boot, i have to connect it to PC and with fastboot run "fastboot continue", but most of the time, it reboots and goes redlight and vibrate 3 times then reboot, so i press the power button and it enters fastboot mode (if connected to PC) or loads charging if connected to wall charger, but it reboots again and goes to redlight vibrate reboot, sometimes it stay charging or in fastboot mode, but only "works" if connected in the USB.
when it stays in fastboot, i do "fastboot continue" and it loads the OS, and it works (well, the things i can do with a broken LCD/Touchscreen, i put my sim card and could call it, and it works, but i cant pick up the call). i can explore the phone memory etc. but if it reboots or if i disconnect the USB, it will almost always turn off. i havn't found a solution (or idea) of what can happen, i dont know if its normal since it has broken lcd/touchscreen or it definitely have a huge problem,
any ideas?
thanks in advance!

Maybe the battery is damaged, and the phone knows it and boots into some sort of safe mode to spare internal damage? When the is has booted you can take screenshots with adb if you have usb debugging enabled. Maybe try see if the os says the battery is damaged?

Well, actually it doesnt seem the battery is damaged, fisically looks ok and it holds charge, i cant debug because usb debugging comes off by default when flash stock software.

Correct me if i am wrong but does the xperia z not support usg-otg and mhl? You could rig the phone up to the tv with a mhl-hdmi cable and maybe use a usb mouse to select things, and enable usb debugging?

Nice idea, now i need to find who in this country (DR) have that adapter

i ordered the LCD screen assembly for repair it myself, but im still concerned about this, as i dont know if it will boot up anyways
my phone right now isnt booting. but as i cant see images i dont know what is it showing.
i noticed the touch screen is working indeed. (when booted, it plays sounds when tapping)
i will wait till the lcd assembly arrives. any ways, any other ideas on what may happen?
the ex-owner of the phone said it started like that when it fell and broke the lcd.

OK now, i've installed the LCD, the phone works, its ON, BUT the Volume Up button and the Power Button does not work when the phone is ON,
the Vol UP button seems always be pressed cause when i press the power button for some seconds, the Phone restarts and not power off or lock/unlock
Service tests: None of these buttons where recognized.
any ideas on any hardware fixes i could try?

I FIXED IT!!
dissasembled the phone, took out the side button flex cable and the volume up button on the flex was dirty, so it was having a false contact. (wich made the button always be pressed)
I took out the yellow tape and cleaned with alcohol and a needle (its so freakin small) and put the tape again and assembled the phone and voila! IT WORKS OK!!

Yes the vol up button pressed means u get fastboot. Now that you fixed the problem and repaired the phone enjoy. Btw nice job getting it up and running.

X98 Air III no longer turns on

Hi all,
My teclast X98 Air III suddenly turned off (black screen) in the middle of watching a movie.
I had no hints it was going to shut down, ie, it had not started to flicker, it hadnt shut down on me before, everything was working as it should do
- except for one thing - about a month ago the sd card just suddenly stopped working, was not recognised. But apart from that, it has been working fine.
Android only - not dual boot. wasnt getting too hot.
Now I am unable to do anything to it - It does not power on, only a black screen, it cannot boot to anything, there is no logo coming up and it seems totally dead.
Is there any trouble shooting I can do to see if it is cactus or not?
I have connected to Laptop with data cable, and nothing
I have connected to charger, nothing
I have held the power button down for 30 secs, alone, with down vol and with up vol and with both.
There are no other buttons or combinations I can try.
So any help appreciated.
many thanks
Siggy

same problem and me...any news , suggestions what to do???

no update. I have a brick instead of a tablet...

Same here. So far I could not find any technical spec or troubleshooting guide.

Is my note dead?

Hello all, something weird happened to my phone today and I would please like some help to get it back working.
So as I was in the ebay application when the phone suddenly froze. I left it for a minute hoping that it will unfreeze but it didn't. So I long pressed the power button in order to do a hard reset. The phone shut down and then its started booting but it got stuck at the Samsung logo with the yellow triangle. I thought that was weird as it never did this before, so I long pressed the power button in order to do another hard reset. But since then, the phone is dead.
It cannot start, when I plug it in the charger the battery icon doesn't show, and I cannot get into recovery or download mode
I have tried removing the battery/simcard/sd card but nothing seemed to work. The phone was running Nightowl's Marshmallow rom.
About a month ago I changed the charging port flex cable with a cheap one off ebay. Could that be the culprit? It seemed to work fine though.
Does this mean the end of the long life of my device or is there any hope of reviving it back?
Thanks a lot in advance

Hello. It is probably a hardware problem. Take it to service center to check the usb micro port, pmc or emmc. Or just leave it alone for some time and try to boot it again.

Screen is dead after disconnecting/reconnecting battery.

My phone went to an endless bootloop after a botched attempt to install TWRP. I tried hard pressing the power button to no avail, and I can't access fastboot either. That's why I removed the back cover and disconnected the flex cable from the battery on the phone's motherboard.
Later on, I reconnected my phone's battery after my shift ended, then I tried to flash my stock rom through SP Flash Tool + bypass tool python script and it went through with a success. However, this time, my screen seems to be completely dead but my phone is still showing some signs of life (short vibration when pressing the power button, but since then it seems that it takes a few seconds more from pressing the power button to turn it on. ) I reconnected and disconnected everything to see whether or not I missed out something but the issue still persists.
The computer reads the device as "Android ADB interface" and the adb console reads it as *device id* unauthorized when I ran adb devices command. There's no notification light whenever I plug it into the charger.
Is my screen dead, or is my motherboard toast? I need to know as I don't want to spend money to buy a replacement LCD only to know that the motherboard's dead. I don't really care about the IMEI as I'm just going to use it as an authorization device for work. I can just always connect to Wi-Fi. Please advise.

One problem after another, so it seems.
Turns out I already unbricked the phone, but the thing is that my display's backlight got busted for some reason. Unless I shine a flashlight through it, I won't know what's in the screen. I'm currently on the way to get a replacement screen, and a new battery cover.
I guess this will be the last Xiaomi device that I'll ever get. This is the only time that I experienced such flimsy build quality since the LG G4.

Maybe you have destroyed a lil cable or something.
