Bricked, perchance? - TyTN won't boot - 8525, TyTN, MDA Vario II, JasJam General

Hey all,
Having served me faithfully for 18 months now, my TyTN has finally given up the ghost. It refuses outright to boot.
Not a splash screen, not a backlight, no response at all no matter how long I hold that power button down.
When I plug it into the mains it displays reddish on the right hand LED, having left it plugged in for a while it stops displaying even that until I unplug it and re-plug it.
I've tested the battery with a voltmeter and the power on the phone with a circuit checker, there's not broken circuitry and the battery certainly generates a current.
Though it's not TOO urgent, as I have a backup phone (Nokia 3220, ugh) unlocked and in use, and it's not TOO horrible as I was about to order a Touch Pro anyway, I'd like to keep it strictly unbricked either for sale or for backup.
Any thoughts on either:
1. What the problem is, I'm absolutely baffled.
2. How I might go about fixing it.
Thanks, Forlornity

If its only displaying a red LED when you plug it in that generally means that the power sensor has been confused or the battery isn't touching the contacts properly.
Are you using the supplied charger or a 3rd party one/usb connection. The usb and most 3rd party chargers don't deliver the right charge. If its underpowered it may not trip the charging sensor.
Try pushing the battery tightly against the contacts, I had a problem whereby the contacts had been pushed in so the battery didn't connect properly.
Clean the contacts with a cotton bud and isopropyl alcohol (surgical spirits) to remove any corrosion. DON'T USE METHYLATED SPIRITS!!! It leaves a residue.
Thats all I can think of now.
Cheers...

Isopropyl you say?
It's a pity, I've actually got meths handy.
I'm using the stock charger, I suspect I might be suffering a RLOD, but none of the usual methods are working...
I'm gonna see if I can get hold of a charging dock for the battery from expansys or suchlike (unless anyone knows anywhere better?), see if that does the trick, if not, new battery, then if THAT fails I'll have no idea
Thanks for the tip on the isopropyl!

My is Wizard Dead. Please help

I got a used wizard today,it is a few weeks old I also got a cradle with it.
I pluged in the cradle to the USB port and the charger to power, after playing with it for 1-2 hours I placed the wizard on the cradle to charge and after a few mins i noticed that it was over heating. I removed it from the cradle right away and noticed that the battery was droping 1% every minute or so. After it was down to 27% i removed the charger and left only the usb connection and placed the wizard on the cradle again. it was charging fine, when it was up to 90% removed it from the cradle and again was droping fast.
When it was down to around 25-30% of the battery I did a soft reset and since then I can never get it to start again also the red charging light does not show.
What the heck is wrong with it? I also get a light burning smell from the bottom of the wizard where the connector is located.
Any help?
I need your lights guys.
Don't like the sound of the light burning smell, that sounds like an electrical fault. It looks like your battery has died and the wizard battery setup is well known to do this. You need to plug it into the official mains charger (not the usb one) as this has an output of 1A, enough to kick start the wizard battery into life and start the charging. You need to wait a short while though before the light comes on. If this fails try to get a new battery and try that. Any more light burning smells and it needs to go back to the supplier.
I would suggest that you send it back to replace/repair. The rapid dropping of the battery power suggest that it is using power somewhere (illegally). I've heard cases of battery caught on fire, etc. and I won't suggest you to use it anymore until you sort out the 'burning' smell.
First of all thanks for your replys.
I pluged the charger on it and the red charging light came on after a while.
charged for over 6 hours and its still red? I think after been charged should change to green? right?
anyways after all that still doesnt want to turn on. I got it to start a couple of times but only to the point that shows the splash screen with the rom numbers and then it turns back off.
Should I give it a smash across the room on the wall? done that with some other things and worked just kiding.
Forgot to add that up to the point when i did the soft reset the device was working fine except the charge drop. Soft reset was done while it was working ( turned on)..... if thats any help.

That ain't gonna do jack sh1t to it. If it can't start to get into bootloader, it can't flash....and it's not a flash issue.
Usually the red light means power but not charging - happens to my qtek 9100 when I let it get too flat and I have to remove and insert the battery while the mains adaptor is attached - others have to 'jump start' the battery by directly connecting to a PSU - I wouldn't do this with yours.
From what you have said it sounds like a short somewhere. Any signs of water damage? Warranty? What Wizard do you have and what country are you in?
Richard
I got the wiza 200 O2 xda mini S from a guy in UK from ebay. The idiot sold me a cradle for it with an adaptor that says 12V on it (Like an idiot that I am i just noticed that) but then again how am I supposed to think that he gave me an adaptor that its not made for it when it says on the back of it "for Imate - Kjam". Do you guys think thats what burned the **** out of the unit ?
dont forget that some times turns on shows the ROMS numbers and turns off.
No water damage... I think its on warranty... I live in Greece.
Might not be the cradle - it could be it steps down internally to 5v. Use a meter and check what it outputs to the phone. Warranty with XDA's are 2 years to the *original* purchaser. As they are only supplied with an airtime agreement then that isn't you.
Richard
have you tried changing batteries to a new one? Seriously, thats the easiest thing you could do right now and you could actually get results.
Ok this is what I did.
Removed the baterry from the device,
got a 12V 1 Amp power supply that I had lying around and give it a few shots connecting it to the battery giving it an electro shock.
(If you're going to try this be very carefull.<<<< DONT LEAVE the power supply connected to the battery>>>> just give it a few shots 1 second on and off.
That was it.
It started working, device turned on and now its charging (I think) yellow light is on.
I'm going to leave it on for a few hours and see what happens.
Wish me good luck. I'll let you know soon.
ok... this is what happend.
Battery is drained and its not charging due to a blown fust on the main board.
I open the phone and placed and solder a little wire over the fuse.
Still does not charge. ^%$#%$#$^%$*
Before I replaced the fuse or should i say short it the yellow light would come on for a few min and then red again. Now when I charge the battery with another external power supply the pda comes on for a few mins and then dies again. ( no charging light whatsoever).
Does anyone know where to get a mainboard for it and about how much it costs?
Asking for help again.

Hey man, sorry to hear about that.
The best you can do is to claim your money from ebay.
You probably killed it when you pluged in the 12V PSU. That's 230% of the normal Volts! Otherwise sell it for parts.
I'm in the process of claiming the money back from the IDIOT that sold it to me.
Lets see if that part of Ebay works as good.

Doubt it. Did you ask the seller for help before opening the phone and voiding the original warranty on the device?

Not a good idea IMO as now the blame is on you as previously he may have been able to get warranty service from the original vendor.
Richard
I did ask.
He is not the original buyer.
what was I suposed to do.... track back 2-3 buyers to find the original... send it to him so he can have it repaired? Anyway it was out of warranty because of the burned fuse that says that some other charger was used with it.
I had a similar thing happen but fortunately not as bad as yours. Twice now my battery has mysteriously drained completely. The last time when I tried to turn the unit on, it flashed the boot screen for a couple of seconds then poof, no more juice. When I plugged it into the USB port, nothing, no lights, no charge, no recognition from Activesync, I thought the unit was fried. I use Tmobile and got to admit they did send me a replacement fairly quickly. Before I packed up my unit I thought maybe I should plug it in using the wall charger and presto, it came on and is working fine. I have no idea what causes this but do know that if the battery is completely discharged the USB port can not over come this to put a charge on.
Same thing happened to me, kind of strange though. The charge was perhaps 70% to the best of my knowledge. I flashed it with Mr. Clean ROM and booted it up.. it came in fine into WM5, then it started the installation of the 3 progs or whatever comes with Mr. Clean.. after the second finished the unit just died *poff*. Screen blank, no responce to power buttons or any other buttons for that matter.
I've tried taking out the battery for different intervals of time, no luck. I've tried using the AC charger, no luck. No lights, sounds, telepathy or matrix ****.. it just lies there like a dummy phone.. hmm what to do. Bought it from a guy in UK (im in sweden) on eBay, don't think I will have much luck there.. even though it's brand new...
Any thouhgts?
I have had this problem - I bought a replacement battery and all is now fine. Another thread in this group states that the battery cannot charge without the OS up - so if the battery is completely discharged then it is impossible to charge through the phone. The only solution seems to be somehow to charge the battery directly - as appears to have been done earlier in this thread.

p.s. if anyone knows of another way to do it I'd be interested to hear as I'd like to revive my old battery and keep it as a spare

Hermes bricked? Toasted? Need assistance urgently!

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...

Think I found a bad flaw in the design of the HD2.

Okay so I got my phone about a month ago, I had kept it stock for a week, went to a custom rom, and put it back to stock today.
Reasoning I went back to stock:
So I had been having an issue of not charging when I plug in the charger, the phone would recongized that it had been plugged in by bumping the battery meter to 100% instead of a charging icon. The LED light was blinking orange & green so I knew something wasn't right. I then proceeded to unplug the charger and saw that the 100% knocked down to 6% which it was at 8% when I plugged it in. After I saw that I removed the battery and tried a different battery ( brother has the same phone) and his was at 70% and I plugged in the charger and still the same thing happened.
So after this I have found out that it was the phone that had the issue as it was not charging the battery at all so I then returned to stock rom using my brothers battery and it still had the same issue.
I then saw the middle contact of the three golden contact on the back of the phone was sticking between the phone and the battery so I pulled out the battery and pushed the contact toward the phone and then I insert the battery back into the phone and then place the charger on it and then it started charging.
So now I need to confirm that this was the actual fix. Can anyone confirm that the middle contact is the actual one that charges the phone or was this just luck of the draw?
sorry for the long post but I thought this would be a big deal based on the design of the contacts aren't the best.

On most cell phone battery packs the center contact(s) are a data or temp sensor connection, the power is input during charging and drawn during use from the outer contacts.
It depends on how "smart" the battery pack is that determines exactly what those center contact(s) do. In sophisticated packs there is actually circuity inside the battery back that monitors voltage, current draw and temp on the battery to determine the battery's charge status and communicates this back to the phone over a serial data bus with those contacts. on simple battery packs the center contacts are simply connections to a thermistor to monitor the battery's temp during the charging cycle, so the phone can cut off charging power if the battery starts to overheat.
In the end, yes, if the phone cant get a connection to those center contacts, it likely will not initiate a charge cycle. Attempting to charge a lithium ion with no way to monitor it is just asking for fire or explosion
d0ug's point above is backed up by the fact that several users have had issues with charging and/or booting the HD2 when that one middle pin gets bent (which seems like a fairly common occurance in this phone).
Ok, so i have been having the same issue and couldnt find any information till now.
Custom rom or not, if the middle term gets bent it will not charge right, also if the battery gets warm to a certain point it will shut off on you. I have also noticed, if your battery is below 50% and your using it intensively it will also stop charging the battery. When the status gets bumped up to 100% the led's will flash between red and green, this usually means there is an issue between the battery being over save charging temp, or a malfunction of the data sensor circuit in the battery. This is built into the hardware of the phone and is a safety measure.
This is from HTC Tech support this morning.
If any one elst can find out anything, im sure there would be people glad to hear.
Too bad the terminal being bent is from having to pull out the battery all the time

I've never had to pull the battery when it freezes. I just hit the red reset button. Is that not working for people?

In my case, I just never have anything pointy enough to press the reset button, at least not as handy as just sliding the batt up and out by an inch or so. I think out of all the soft-resets I've done on my HD2, maybe 2 were by pushing the little button (yellow in my case)
hmm, i just checked my center pin, its still good. Like someone said above, i also reset my phone by just poping the battery out.
Also in the same situation that i usually don't have anything around to poke the reset button. I don't think ive ever actually used the reset button yet. All my previous WinMo phones had a stylus and the reset button was on the outside of the device, no battery cover removal, so the reset button was convenient to use. Battery removal seems like the simplest thing to do, if you're already removing the battery cover, just pop out the battery
How often are you guys having to reset your phones that way that you are damaging the pin, are you rocking the battery into it, or kind of just pushing it in? i noticed that the contacts seem to only fold down, they don't fold up or push in.
Ill definitely keep in mind now to put the battery in with a slightly downward motion to make sure the pins fold down, and don't get mashed in, which is where im guessing the bending is happening for you guys
My left pin got bent from all the battery pulls I've been doing. I think it happens when you don't slide it in at the right angle as d0ug has suggested. Now every time I do it, I make sure that all the pins are contacting correctly. If my left pin gets bent outward, the phone does not power up at all. (which made me freak out thinkin I broke it) Both stock and cooked ROMs have required battery pulls occasionally. Overall, I think I have to do battery pulls WAY WAY WAY more than I did with my previous MT3G. So far I have tried Kumars and Elegancia ROMs. I wish I could find a stable ROM that requires zero battery pulls. =T
yupp had the same problem with the connectors under the battery
I went in for a refurb and used it for a day and that pin was already bent so i went back in and this one seems to be in good working condition.
I think they should have done better job with the pins as I have never had these issues with any other phone.
WOW!! that fixed my problem.
*sniff* I love you guys! Thnx for the fix!
I'm trying out a couple of HD2s that an acquaintance had no business getting and is now looking to unload. The one is practically right out the box, the other looks like it has been around the DC loop a few times. I'm testing the well travelled one out when it looked like it needed charging, so I plug it in and start looking at the nice one. After 2hrs, I hear the tramp vibrate. When I go to see why it vibrated, it won't turn on again! It's after midnight, I haven't purchased it yet, haven't loaded a cooked ROM, haven't even run a stock update and it's already screwing up!?!? Since I had two I did some battery swaping then both went into boot loops. Many hours and a few gray hairs later, I got them both working again. I left them essentially alone until today. When the spouse went to sync the well-used of the HD2s, he noticed it needed charging. After almost an hour, he noticed that it had less charge than when he plugged it in. I noticed the charge light wasn't steady, it's flipping between red, green and nuttin'. My spouse, who had already laid claim to this HD2, did as he always does and jumped to the worst conclusion. I said make no inferences until we get home and check this forum. I knew you'd have the answer and you did not fail me! Best yet, it cost me nuttin' to fix!! Now do I point this out as a flaw for potentially lowering the sale price?
Thanks again!!
My take on this is that the flaw is in the way the battery wants to come out. When you lift using the tab on the left side, it tries to come out at an angle, angling from top left to bottom right, which means the connectors come away unevenly, and since the connector plates on the battery are inset, the plastic of the battery casing catches the pins as the battery rotates on its way up.
I keep my thumb on the battery just above the sim card until the battery is out about 45 degrees both top left and top right, and then pull it towards the top of the phone so the connectors all come away evenly, rather than being dragged up and over the pins.

[Q] Red Light - Charging without back?

So, I plugged my Nexus 4 into a generic car charger and it went black instantly. The battery was at about 92%. With the hope that a proper AC or computer USB charge connection would bring up the white battery icon and fix things, I stopped by an out of town T-mobile. The manager tried the button battery-reset (up volume + power for 60sec) and I googled alternatives and tried the - enter recovery by pressing those buttons for 15sec off the charger and connecting while still holding down the buttons - trick. Neither worked.
The manger seemed familiar with that and the other button pressing tricks, and said that really, my only real hope would be to reset/replace the battery, but that would void my warranty. However, although the T-mobile site claims my Google bought phone is under warranty (and I've been paying for it each month), technically, it isn't. Under them or Google (any more). So, I purchased the tools to open the phone, as well as a replacement battery. In the interim, I tried to use all the button combos and various charging connections to get it to come back to life. I *did* manage to get it charging the old battery. I know because the blinking red light turned constant for an hour or two, and the battery got warm. I can only guess that the battery was too damaged to keep the charge however, because I could never get it to turn on during or after. My best guess is that the software battery reset allowed the phone to send a charge to the battery - at least once.
After getting my tools and replacement battery, I managed to get the phone open (with great effort - I think there must be a difference between batches there). I removed the old battery connection and looked to see if I could get the charge icon with it unattached and on the charger. I couldn't. Reconnecting the old battery didn't seem to make any difference.
I was about to go through the process of prying up the old battery when I realized that you can actually connect the new battery to the board connector without getting the old one out. So I did that. Leaving it charging like that for awhile didn't do anything, so I decided to do another software battery reset and I'm letting it sit on the charger overnight. All of this has been without reattaching the back.
So my major question is - does anyone know for sure if the phone actually charges the battery with the back off? I know there are important circuits there - which seem to shut down the phone after the battery or google image when not detected (at least that's my deducement after reading posts). But are those connections also used in charging? The Qi goes though the back to the charger function, so perhaps that connection has to be there? I would like to try and find out though beforehand. It took 2 hours and two mangled guitar picks to get it open the first time, and the second may be just as trying. (And believe me, towards the end, I was not concerned with being gentle.)
I am also curious about the four prong battery connection. I've seen the post about charging the battery using external sources by connecting to the two outer pins. Does that mean the two inner pins constitute a second circuit between the charged battery and the phone? And if I find another 3.8v battery fully charged, I could perhaps connect that to the phone instead by wires and get it booted into recovery? As to why I'd want to do that, I don't recall the last dated CM version I had installed, so finding that in their folder plus pulling off everything from /data... assuming I replaced this with another Nexus 4, I might be able to save myself a lot of setup hassle.
In terms of the red light... it actually seems to be an error code. When triggered, it blinks 7 times, and on the eighth stays lit for a bit before repeating.

As to why I'd want to do that, I don't recall the last dated CM version I had installed, so finding that in their folder plus pulling off everything from /data... assuming I replaced this with another Nexus 4, I might be able to save myself a lot of setup hassle.
In terms of the red light... it actually seems to be an error code. When triggered, it blinks 7 times, and on the eighth stays lit for a bit before repeating.

I RAN INTO A SIMILAR PROBLEM
I found that holding the power button for a while allowed my nexus 4 running stock Lollipop 5.1 to boot back up.
Have considered that you may have a faulty USB port ?
Just pop the old battery out install the new one plug in the charger and it will charge. You can boot up without the back on. The back contains the antennia.... and the NFC circuit board.
Good luck

Well, still no luck. I ended up putting the new battery in and closing it up to try the Qi charger, but all I can get is either 7 or 10 red blinks followed by a short solid light. No white battery charging symbol or anything else.
When you say a faulty USB port, what are you referring to? The cable works (though I've also tried my Nexus 7 one too) and even though it won't boot, my computer does recognize that something is there when I plug my phone into it (it just can't figure out what's plugged in - which is normal). I want to say that it's trying and failing to charge the new battery. At this point, I think the charger messed up more than just the battery.

Battery died and now its not charging

My battery just did and no blinking lights. Now my phone won't charge. Can someone help?
Could be manufacturer defect. Your only option might be to contact BlackBerry and have them swap it under warranty. I would just to be safe.

This happened to my Nexus 6 last year, ended up having to get a replacement from Google.
Problem with Battery
If your handset is a new one, then a replacement or you may visit to store & get it checked with a professional.
If It is new smartphone, then you can replace it. Other wise I do suggest you to do that first remove your battery and clean with soft cloth and put after some time then check it. It happens some time it will not showing charging. Sop always remember that charge your mobile, then battery percentage gone below 10%
Priv is crap

The battery does not come out of the priv. Thanks for suggesting something we can't do. Good going.
replace the battery
it could be the battery NOT a defect
Hopefully by now you found the same advice on CrackBerry as I did last night - just hold the power button on the left of the phone until it comes on.
Mine has adopted the habit of not appearing to charge or do anything once the battery hits '0%' and dies - it can lay dormant for a few days even - my advice is hook it up to a micro USB cable charging with at least 2 Amps, then hold the power button until it starts. This can take 30 seconds or more.
And for those helpful people guessing you can swap out the battery - they obviously never went near a Priv.
I've had this issue multiple times. Solved (note, not trivial, skills and tool required!) by plugging it into a decent charger for an hour or so (might not show its charging) and thereafter removing the back cover, unscrewing the battery connector, and removing it with a pair of tweezers. Amazing that the phone comes back to life when you plug it back in. I didn't replace the screws on the battery connector so its easy to do in future.
Try using a high voltage charger, such as the one in the car...It works for me
