Bricked, perchance? - TyTN won't boot

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!

I have the same problem, and new battery didnt help! anyone got solution for this problem? I menage to charge battery with 2 wires, and phone starts, but it wont charge! i mean orange led is on, and it says CHARGING, but battery % is going down down until it reaches 0%!

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.

[SOLVED] Issues after display replacement [LG G2 d802] Red led blinks 8 times + more

I don't know if this is the right section, anyway because it isn't specifically hardware related I posted here... for admins feel free to move in the appropriate thread.
My G2 dropped on the floor and as result I got a complete broken display plus not working touch.
The device, touch apart, worked without issues so as 1st step I made a full backup of sd-like content (music, pictures, etc...) to my laptop.
note: even if touch didn't work I was able to access the device trough adb and a very useful utility (http://marian.schedenig.name/2014/07/03/remote-control-your-android-phone-through-adb/)
Next I ordered a replacement for the display, looked for instructions and changed by myself... and the phone didn't boot or even charge... nothing, the only signal of life was when attached to the wall charger the led blinking in red eight (8) times consecutively then no blink for a second and again blink for 8 times and so on in an infinite loop.
Of course I started to look for solution and tried every kind of combination but none worked.
I started to think that I missed up something during the display replacement or the battery fault or even I fried in some way the motherboard, anyway for what I read it supposed that could be that the battery gone under certain voltage or minimal charge so the motherboard circuit didn't recognize as "good or safe battery", it is simply bypassed by charge circuit.
note: I waited for the new display about 10 days and the device (fully charged) slept (turned off) in a drawer so I don't think it was totally discharged
I disassembled and reassembled again the device but nothing happened so while looking for a solution I saw a video on Youtube (https://www.youtube.com/watch?v=MZwknmWCmOE) solving a issue similar to mine so as instructions I took an old charger (800ma), cut the charger connector and exposed the 2 internal wires (one red and the other gray/black).
Then I opened the device, disconnected the battery and attached directly into the battery connector the two charger wires (in this way mobile motherboard is bypassed).
I used a small piece of tape to stop and make touch laterally the 2 wires to the connector, something like: dark wire -> [ battery connector] <- red wire
Keep in mind that the connector is something very small like (0) where left parenthesis is for dark wire and right parenthesis for the red one.
note: you can't wrong with wires, because the positive (on the battery connector) has a small white triangle.
Of course I found a way to don't move/mess wires before connecting the wall charger... I put another piece of tape at 20cm on the table to keep the cable charger fixed near the phone, then I attached the wall charger...
remember: attach the charger to the wall ONLY when you have finished to place/fix the contacts!
Waited just 1 minute because exposed charger wires was very close and didn't want to fry something... but it was enough!!
Reconnected the battery and voilà the phone turned on!
The phone turned on with almost 80% of charge, all seemed to work... except that I found 2 issues... I suppose because the case didn't match perfectly anymore (I opened the device 4 times and disassembled-reassembled twice)
1st speaker didn't work, so I reopened the device and checked the speaker connector, I discovered that the speaker didn't touch very well so I put a small stripe of tape under the connector (the small vertical green stripe in the lower side of the phone) to lift it and making touch stronger with the speaker module (the black part the come out), here on Youtube for reference: https://www.youtube.com/watch?v=XE2FPmFUrQQ
2nd GPS didn't work very well (discovered after a couple of days) so I reopened the device and applied this solution that worked perfectly: https://www.youtube.com/watch?v=dfS4LpfcLfg
This is my story in the hope to help someone, if you have apparently a total dead phone and the only signal of life is a 8 times blinking red light... now you know what to do!
Regards,
Davide

Thank u for share your story

Congrats on fixing your problem!

You mentioned the alignment of the phone wasn't the same as before....
Did your battery swell or change shape at all during this process?
If so could be a sign its on its way out and needs replacement.
A dying G2 lithium ion battery changes physical shape and completely alters the internal alignment of your components.
May be worth an extra 10.00 to replace your battery at this point with a new one

thank you, I was a bit frustrated because I thought to have broken the motherboard, even if it wasn't very easy I didn't surrend and I won!

I understand what you mean but no I don't think so... it seemed the same size
anyway battery has less than 1 year of life and never showed symptoms or bad behavior, right now is running as before... I can pass easily 24h without recharge

Have you found the source of your alignment being off?

I checked and found nothing in particular... just a bit near the sim "area", but it seems just a sort of plastic adaptation... as mentioned before I opened, disassembled, reassembled and then closed it 4-5 times (in just few days)

Edge 7 freezing, no power, overheat

Hello people,
I have problem with my Samsung Edge 7 and please if you can just tell me what can be a problem and on which way should I go to solve this problem I would appreciate it very much. No need for step by step solution just tell me what can I do except send it to Samsung repair shop or recycle it. I will take it apart by myself if needed but I don't have a clue which part should I look to replace or what.
So... the problem is that I manage to charge the device one day when it don't want to charge and after that I managed to turn it on. Everything was working fine, didn't try anything much just unlock screen and put it to sleep.
After that I turned it off so it don't consume battery while I would be able to backup my data. When I was able to do backup I turned it on and it powered up normal so I proceed to backup my contacts (export to SD card).
When the export finishes phone just froze and I have to turn it off with POWER + VOLUME DOWN button combo.
After that few times when I try to power it on it just froze on boot up logo and I turned it off that few times with the same button combination as before. Until it don't want to power on anymore. So I tried to put it on charger to see if anything will happen, and nothing did.
I just left it to sit on my desk and I noticed that the phone is heating but I got no reaction at all from the phone (powering on or charging)
The day after when the battery was drained obviously I managed to charge it up again but when I power it on after it got to 100% charge it froze again and there goes same procedure as before (button combination restart, no response, heating, battery dead, charging...)
So now I can't even charge it anymore and I took out SD card to check if my contacts are there at least. But nothing, that contacts vcf file is not even saved on SD card even I choose that option when exporting my contacts.
Now I don't know what else to do since my phone wont even charge or power on and I would like to backup my data at least and then I can recycle it if I must.
So please if you have a clue just tell me where can I look at what can I try to do.
Thank you in advance and have a nice day

some of sgs has these problem. The motherboard is broke, i had same problem and sent to samsung service, they changed motherboard. I guess it's related to cpu temp sensor, inside the cpu.

Thank you Ganjax for your reply. That was the thing I was afraid of. So all my data goes away with motherboard?
I will wait few more days with some replies even I find your very useful and accurate since you had the same problem.

hey I also have the same issue, putting the phone in the freezer and letting it freeze makes it so that it can turn on for only 5minutes or till when it drops back to room temperature hopefully this will be enough to get your photos back.

millkyway4 thank you for you reply.
I am not in a possibility to try your method because I disassemble my phone and striped down battery for research purposes.
Neither I think that those 5 minutes will be enough to transfer all my data but if I ever reassemble my phone I will give it a shot.
So... Considering my research and striping down the battery the things goes like this (if someone is interested in this topic):
I disassemble the phone and remove the battery. Battery is connected on motherboard by some connector that I don't know the name or type, so if someone knows I would like to know too.
Since I couldn't find positive and negative lead on that connector (because of microscopic leads) little bit down on flat cable, near the battery, I removed coating and manage to find leads and measure voltage of the battery to confirm positive and negative lead.
By the measurements I assume that battery voltage is fine (~3.7V), but when I connect it to external charger which have built in ampere meter the battery doesn't charge as other batteries and ampere meter readings vary by 100mA +/- I set up to be initial charge. In normal case when I charge batteries amperes only goes down by the time the battery charges so I find this event an anomaly.
Since that is the case I removed the chip (from which the flat cable is coming out) that is on the battery assuming that it is causing that anomaly. Leaving the battery with only positive and negative lead that I connected and also measure and put on my external charger. But the same thing happens as with chip, or what is called, on the battery.
Going further with my research I cut down flat cable from battery chip (electronics) and connect positive and negative lead, I found before, directly on my charger on which I adjust voltage on ~3.75 volts and connect the connector with flat cable back to motherboard. So you probably see what I did here but if you don't the research I want to conduct is that my external charger acts as battery for the phone and I try to power it on like that.
In this case ampere meter shows 0 since the current which is flowing trough the phone is none. After I am sure that this is the case I tried to power on my phone with connected external charger like that and my ampere meter shown a current draw of 100-200mA on the POWER button pressed but the phone doesn't turn on.
So now I need someone with a little bit better knowledge of the phone, batteries, working order and type of connections like this to tell me what did I do right and wrong so I can prove that Ganjax statement, and my assumption, that motherboard is dead is really correct.
Ganjax don't mean I don't believe you or something, I appreciate your reply, this is just for research purposes because I would like to play with this stuff and that is the things that interest me.
And if there is some "fanatic" like that to tell me what can I do next and try or point out what should I do and don't make next please leave a comment and we can discuss this matter together and find out something about this case.
Thank you all and have a nice day

Signal drops after battery change.

I have a problem with my Axon 7 (global). Ive decided to change battery on my own one week ago. I was super carefoul with every step i did, no cracks, no damage. I assembled everything togeather and suddenly no signal. Wifi worked perfectly. Now i have this often signal looses which persists even after reboot. Sometimes when I finally catch signal it shows me almost full 4g+, but on the other hand everythig works very sluggish. Super slow internet speeds, even for messeging via whats app for example. I tried to check if this is maybe some software issue. I was on global B03. I could not update to B04 via ota so i decided to downgrade, then install b04. I did, and this solved nothing. Problem persists and phone without wifi is unusable :/ Any ideas how to solve this?:crying:

Connector not seated properly inside it?
I also replaced my battery. The battery behaviour is now normal again but seen no differences in how it runs.

I think that it's not that, I've payed extra attention to this second time that I opened phone. All the connectors I've unplugged, then plugged it again, checked antenna as well. No visable damage to the cable or the connectors.

Thinking about my experience doing the battery, the two most difficult or potentially damaging things were separating the rear cover from it and getting the battery out. Once the cover separated it came off well. It was a hard job getting down under it. The battery was hard to start lifting but with isopropyl alcohol under it, It came up easier the more it was lifted. Maybe something around the battery has been compromised.

Thank you for your response. I did not use alcohol to remove battery, i used hairdryer, and i began to remove battery from other side (the one with antenna). Maybe i burned antenna? Is it possible? Sryly no visible damage, nothing! Everything else works. BT, Wifi, all functions - only signal problem. Any idea what part should i change? I also founded some info in iOS forum somewhere, supposedly iPhone 6 or 7 had similar issue when someone changed battery. They suggested to unplug battery and hold every button for 30-60 seconds, one after another, to "discharge components" or something. I dunno :/

You change the charger board too?

I ordered from Ali only antenna, should i order charging board as well? Anyway, why charging board? Is there some important components that i could have damage? Why not motherboard as well? Antenna is connecting charging and motherboard together. Just wanna know why do you think that i should change charging board as well, maybe Ill learn something new
