Hey there. I've got some problems with my Wizard ...
One of the 6 soldering points of the headphone output was broken (insulate contact). Cause I don't have warranty left I decided to solder this little contact problem on my own, because the soldering point was big enough. I'm very sure that I did not touch anything else than the tin-solder, but now my Wizard freezes sometimes with some weird behavior:
First all LEDs light up, the display lights up to completely white very slowly. After about 20 seconds the flashlight on the back lights up and flickers. At the same time noise comes out of the speakers. After that it reboots.
I cannot reproduce it. It happens when a text message comes in, sometimes it happens when i shut off the speaker through the com menu and sometimes it happens when i enable bluetooth. But not every time ...
FYI, I already did a hard reset, replaced the ROMs with others for this model (Qtek, Mr.Clean, O2 ....). I have checked everything on the PCB very pedantic but I cannot find anything ****ed up.
Somehow I don't believe that my soldering has provoked this problem, but I also don't except this.
Maybe anyone of you had something like this before and solved it? Or has anyone an idea what part could cause this malfunction? Is there some kind of "Error Logging" Tool where I can see the last action (maybe kernel command or something like the event viewer that logs "bluescreens") that is perfomed before it freezes?
Thank you in advance!

Just to check. I had this experience of soldering stuff near a IC chip that the heat actually being transferred from the wires into the chip, with high enough temperature to cause problems. So, is there any IC around the part where you solder? Also, many of the new stuff are surface mounted, and enough heat conducted on the wiring will be enough to get some of the connector loose. Just double check that.
Hey again!
I just want to thank you! You saved my Wizard
What I did was I disassembled the Wizard completely, put it together again and tried to start it up. This failed, cause the battery was completely discharged. After giving it multiple pushes with a 9V block battery the Wizard loaded up and since then i did only have a crash when disconnecting and reconnecting the cable (I think due to the low battery voltage atm).
While cable is connected, I can en-/disable flight mode, receive text messages and enable bluetooth without a crash. Seems something went wrong when I put together the Wizard before (thinking of vibration alarm, because when you receive messages it vibrates, if you turn on flight mode it vibrates ....).
Thank you! XDA-Developers is gr8!

Before anyone jumps on me, I've been going through the Wiki and forums extensively, and found just one similar problem. Which wasn't solved...
My HTC TyTN/Hermes 200 won't boot up anymore. It is totally dead. I even can't get it into bootloader mode. Screen stays blank and the LED is off.
Put the (3 months old) battery in another Hermes to test it, and it's at 100% charge.
My Hermes shows a steady red LED when it's plugged into power without the battery in, and no LED at all when the battery is installed. The red LED turns off when the battery is installed while there's power going into the unit.
I've left the battery out for at least an hour, plugged it back in, same results. Like the other guy I tried the "pull power, pull battery, plug in power, plug in battery, reset" trick http://forum.xda-developers.com/show...6469&p=1077622 - to no avail.
Does anyone have any last resort ideas on how to get it to at least come back up to a boot loader screen ?
check the battery contact points on the phone. the hermes shows a red led when its plugged in but without a battery
... have you ever dismantled your hermes? your screen ribbon cable may have dead tracks or not be connected properly
just a test on the opposite side of the battery connectors with battery removed press firmly without putting pressure on the LCD, this worked for me when i had a white screen on power up.
if this fixes the problem you may need to actually dismantle the back and put some flame retardant electrical tape on the back over the existing tape to add an extra layer of pressure and retension

Yes, I have cleaned the contact too, nothing. And the battery is OK for sure, my colleague's TyTN runs on it without any problem.

In fact I have, I have totally dismantled and reassembled my TyTN yesterday afternoon, nothing.
the only other problem may be that when being dismantled you may have damaged some sensitive components, Electro Static Discharge will fry sensitive CMOS components, they do not like it at all, whenever dismantling you should wear an earth strap, any time i dismantled mine it was on a workbench with a static mat and i was earthed through the mat.
but this is one possibility, the only other idea is to swap main board and displays with another that works, finding someone willing to allow you to do this with a working hemes is the tough part.
thats as much all i can think of for now
R.I.P. my trustful Hermes 200
Thanks all for your assistance. I have come to the conclusion that my sweetheart is no longer among us. May she rest in peace.
I have obtained a (2d hand) replacement yesterday. May this one last longer.
I'll keep the old TyTN for replacement parts.
Oh well...
Hi, wonder if someone else has had this problem.
My HD 2 will only sleep when on mains power. If it on battery when I put into sleep with the on/off button it comes back on after 1.5 seconds. Same if you wait 30 secs for it to go into sleep. To fix it (temporary) I have to put it on the mains for about a minute and then it behaves itself until the battery is about 50% and then it won't sleep again. This obviously drains the battery.
I have 'hard reset' the device and it is still the same. I also updated the rom from Vodafone support site. Still can't fix it.
Can anybody out there help please, it's driving me mad!
I have this happen every so often. fixed by plugging into the usb cable (doesn'tneed to be plugged in). what I understand happens is in the usb port a connection gets wobbled and stops sleep. sometimes I have to plug it in and out a couple of times.
Thanks
Thanks, didn't try it without power. I'll just carry a mini usb connector with me! Thanks again.
that's what I've started doing.
The USB insert actually doesn't work
Hi, tried the fix suggested but it doesn't work for me. I have to have the power supply live to make a difference.
Any other ideas?
sometimes it can take a few attempts. I normally soft reset first to see if that fixed it first. other than that I don't know.
sorry!
mine's started doing this now.. yey! rinses the battery too while its stuck on.
Tried a hard reset, even a different ROM and hasn't fixed it.
I'll try a different radio next
Anyone else got any ideas? is there some software that can monitor inputs to see what it is that's waking it up?
Spike
^ different radio didn't fix
Hey.
I had this, but after a while it didn't only do it on mains.
It started to do it all the time, and as you can imagine that was killing the battery.
I tried everything! took everything back to exactly how I got it and it still did it.
so I took it in for repair, they sent it back to me and it had clearly been opened up, and the screen was brand new.
If yours is still under warenty, take it to get fixed.
I spent a little over a month looking fro a fix and nothing worked at all.
Last 3 days i also have this problem....
Anyone found what is causing it or sending it for repair is the only thing to do..
anyone please?...
Press a button .. fixed
Haha
Mine does this too all of the sudden.
There is a very, very easy fix for this...
press the right lower button (The hang-up button)
Battery life is extended from 1 day max to 2-3 days standby even!
It used to go to sleep automatically tho.
I think I probably 'tweaked' it with the tweaking tools and that's why
it does it. I'm too lazy to turn it off - and - to be honest - it's good if it's on all the time. At least my GPS won't just stop the readings I take all of the sudden.
And after I'm all done playing with Navigation, I can still press the little button.
(It really IS NOT that much of a problem to quickly press it)

You might want to install the S2U2 program, and let it manage your power settings. I've found it to be much steadier and more reliable, without those sudden wake-ups and battery draining issues.
I don't think it has anything to do with software.
It is clearly a hardware issue
I had the same problem. After inspecting the usb close, i found that there is some dirt and/or corrosion at the contacts.
I cleaned them up using some spray for electic contacts and problem has gone for almost 1 week now.
I read somewhere on XDA that an other member tryied the same thing, problem solved but came back after a while...
Anyway the fact that i cleaned the usb and the problem is gone for now shows that is clearly a problem with this part of the phone..
solved
i two have had this problem and have just found out how to sort it out. basically i tried everything new radio, rom, getting rid of CHT
and in the end all it was is the usb connection!!!!
all you have to do when unplugging your usb cable is make it come out on a angle left to right. there are obviously some very delicate contacts that get knocked out of kilter making the phone think its still on mains power when its not hence never turning off
you can confirm this error by unplugging your phone going into backlight settings and seeing if you can adjust you light setting on battery power if when you adjust your light setting nothing happens you got the same prob as me
Well, mine was fixed by a hard reset. Been testing it since, and it hasn't failed to go to sleep now.
Since there's a few different "fixes". might be a couple separate actual causes.
Started facing same problem when was on hols in +40 and quite humid atmosphere. Connecting cable helps but only if the cable is plugged in power socket or computer. And that is actually a problem as I do switch often between Android and WM and after restart HD2 doesn't go to sleep
Did this two months ago with good results ;-)

When I suffered from this problem a couple of months ago, I was flummoxed at first.
But then I decided to use a strong (20 diopter) magnifying glass to look at the ports and buttons of the phone. I could not imagine the amount of gunk I found inside the USB slot.
I cleaned with a very very small cotton swab dabbed in cleaning alcohol and wound around a pin and the problem was solved. Power consumption at rest went down from 30-40 to 4-9 mAh.
I now do this every few weeks.
I try the following, it works :

Weird problem but my phone has a screen that shows a distorted display or sometimes just speckles of random color. It seems the problem mainly occurs when the phone has a SIM in, gets hot, or maybe humid.
I ran stress tests on CPU and GPU for hours with no sim and it worked perfect. Then I put the sim in and later the display went crazy (this is not a touch screen issue). Then I took sim out and it went back to normal. I thought I fixed it by blowing out sim slot, but then the problem reoccurred. I had to take off back of phone (while it was on) and it was immediately rectified. It makes me think that something is getting pressed down too hard. I tried disconnecting the video cable and reconnecting it to see if that will fix it, but this particular phone has not been opened since the factory so it seems weird that it would suddenly get a loose cable.
Any ideas appreciated. I would like to fix it.

Had this issues after replacing my display!
Antenna cable is near the display eletronic parts in the lower part of the phone, near the usb connector, you've to put a tape on the eletronic, or you'll ever have this interferences when you use the antenna! (Antenna is the grey cable), display elettronic parts are a little square, betwen battery and USB connector, and have the grey antenna cable on them beacouse the antenna connector is near in this part of the phone! Sorry for my bad english, hope this help you!

I haven't replaced the screen on this phone, but when I took off the bottom piece the connector just fell of lower control board. I snapped it back in and we will see. Maybe it simply got loosened somehow by shaking etc... Hopefully that rectifies the issue. Thanks. I was going to swap the lower board (I already swapped upper one) but maybe I can avoid that now.

Can you post a photo taken by other phone (not a screenshot from your G2) showing your G2's current problem?

It was the lower connector like was said earlier in the post. I had already swapped the upper board with the other phone and the problem continued, when I went to mess with the lower board the connector was loose and upon tightening it down it started to work. I have had an instant of glitch two times in the long period since then, but it goes away immediately. It seems the connector need glued down or something who knows. I am happy though it is working well enough to last me until something comes along that makes me want a new phone.
Let me start from the begining.
So the other day I plugged my phone into USB in order to charge it (I had to keep it close to me hence why I didn't plug it into the wall charger). The phone was charging, showing up as a media device on the lappy, etc. I was doing stuff on the computer then I heard it vibrate so I went to see what it was. The blue notification light was on (facebook notification most likely) and when I pressed the Menu button the screen didn't come on. I also tried the Power button but same thing. So I decided to restart the phone. Since then, it hasn't turned back on.
I tested the battery in another device and it's working perfectly fine. Neither recovery nor download mode work. I tried to do some of the tests people recommended for sudden death, like plugging it into usb and leaving it for a while, trying to kick start it (putting battery in while holding the recovery buttons) - you name it, i've done it. I even went to the lengths of taking off the back cover to see if theres any crap that got in there, maybe a loose connector, anything burnt - nothing. Unfortunately, I don't have a multimeter to see if there is a charge running through the board. Looks like sudden death to me, the only thing is - I rooted the phone on the 1st day I got it and I don't live in the country where I bought the phone so sending it over for warranty repairs would be a pain in the ass. What can I do? I would greatly appreciate your help, if you manage to help me fix my baby, I will ENSURE to send you a donation for a nice, big, cold beer (or maybe a few).
Looking forward to any answers! I really need my phone, I use it for work.
It seems like a hardware issue... you need to take it to a local store to scan it's hardware.... maybe something gone wrong while charging which made something be destroyed inside it..... hope its not the motherboard.....
it happens sometimes, when charging current fluctuate, it destroys the charging circuit and in result it damage the whole current circuit, local repair shop can solve the issue.
Hi, my phone with just three weeks of use, my screen stops working suddenly after ending a call. At that moment I see that the screen does not turn on, I press the lock button and I hear the blocking sound, I proceed to remove the battery and turn the phone back on, but the same thing happens. I do not have a boot image (no LG logo, nothing, only backlight for about 2 seconds) when the backlight is turned on the screen, the bottom edge of the screen gets very hot (even faster and much hotter than the CPU) . The phone reacts, I receive calls, notifications, but I have no picture on the screen. Okay, I'm starting to think it's a hardware problem and I disarm the phone to check that the LCD connector is not badly connected, but everything was fine. I assemble the phone and turn it on again and I still have no picture. I leave the phone charging all night and I go to sleep, the next day the screen worked, but only a few minutes, until it became pixelated as in the attached image.
Now the phone does not give image (only backlight) and only sometimes gives me image, but pixelated. I have been investigating, and the only thing I could investigate is that it can be screen (flex ribbon damaged), overheated GPU or CPU, defective GPU. So I do not know what to do (a replacement is not possible). I need to know if the problem is the screen or the motherboard, in case it is the motherboard I can bake the motherboard in the oven to try to perform a reflow of the GPU, just as it happened with the LG G3 when it reheated and this was a solution.
What do you think is the problem? Sometimes when I have pixelated image and I turn off the main screen, the time shows perfectly on the secondary screen without pixelation
I'd first check the ribbon cable and any other cables or connections to make sure that's not an issue. If it is the GPU, please, please take it to a professional who can reflow it correctly. I can not stress this enough -- the risk you are taking by putting your cell phones motherboard into the oven is astronomical. You could essentially take a phone with a GPU issue and turn it into an everything issue. :\ I used to repair Xbox 360s and Playstation 3s for a living and I had a BGA rework station, you have no idea how many times people brought in baked motherboards from attempted home repairs. You can find these services cheap all over the internet. Just make sure you select one with plenty of positive reviews.
Edit: I also don't recommend a heatgun reflow unless you have something to mount the heat gun with so you can attempt to replicate a BGA rework station environment. If you are dead set on repairing this yourself (if it turns out to be GPU that is) -- then I highly recommend doing this instead of the oven. Watch lots of youtube videos first. PM me if you have any questions. I can't promise I'll get back quickly as I have stuff to deal with here hurricane wise.
