[Q] First time charging-question - One (M8) Q&A, Help & Troubleshooting

Hi all m8 users!
I just bought a new htc one m8, it's still in the box and I am super excited. My question regarding the first and also other charging is this: how long should I charge it now? Until it will show that's it's fully charged? Or wait some more? Shall I leave the phone off or can it be turned on? I know it may sound funny to some of you, I just want to make sure I won't destroy the battery. To get the most of it
Thank you for your answers and advices.
Martin

Just plug it in and charge it full. You should be good to go.

Do whatever you like apart from trying to discharge it after its switched itself off or shorting the pins in OTG mode.

After self turn from low battery, Desire wont turn on

Hi to all, last night my desire ran out of battery and i' was nowhere near my charger cause i left it at my office.
i try to turn it on and send txt message but it was automaticaly turned off again before i can get to the homescreen.
without waiting too long i try to turn it on again and still i can't get to write a single letter cause it was automaticaly turned off itself again.
this morning when i get my hands on the charger i quickly plug the charger but the amber light aren't turning on, yes my desire wont turn on either, i try to connect it with adb and when i type adb devices the adb tool shows there are no devices connected.
Please help me how to turn my Desire on again, fyi i already plug the charger for more than half hour without any led on my phone lights on.
Anyone knows any workaround on this problem, maybe experiencing the same issue?
Thank's in advance
If you're using the stock battery which is Li-on, then the problem might be that you killed it by forcing the usage after the shutdown. Li-on batteries should NEVER be juiced out to a true 0%, or it will die. That's why the Desire turns off most of the time between 10-15% to make sure this doesn't happen. (Other mobile phones do this too, but they report it to you as 0% instead of the arbitrary 10-15%) I do hope so that this is not the case with your problem. Sorry if I only gave an explanation instead of a solution, but that's all I can think about right now.

try removing the battery and put it again. then plug the charge. wait for some time. hopefully it should fix it, else you need to try replacing your battery if it was not replaced recently.

Thank's a lot for your respond my friends
My friend help me by trying to manually (connect the - and the + terminal with his blackberry charger) charge my battery for about a minute and then quickly insert the batt and plug the charger.
The orange light lit again but it took about 7 hours to reach 100%, after i unplug, the batt went down faster than Rossi's motoGP bike
2 hours standby and it went off.
I thought it better be charged again with the phone off and so i did.
After about 20 min, my phone vibrates as if there were a call coming in (phone was off) so in a rush i quickly unplug the phone and took the batt off (i'm worried it will damage my phone)
Since then, the batt won't recharge AGAIN, the orange led aren't lit no more.
Sorry for those long letters, one more question, do you guys think i have to get new battery or should i try to do the charging again?
Thank's in advance
My bet is the battery is gone

New battery is about £35.. dunno how much that is in Indonesia. I'd strongly recommend buying an original battery also, not a cheap knock off - bad ones can have very poor battery life, overheat, melt (even "explode" sometimes), and just in general kill your phone.
thank's a lot guys, will be lookin' for the genuine replacement today, tell ya the result later.
Thank's again for answering my worries
edit:
Ok guys, i got my genuine new battery which cost me around 24-26 Euro's
Test the battery at the store to show that it was charging and it was charging ok so i turn off the phone and go home.
Plug the charger as soon as i get home and the orange led didn't lit, to make the story short i presume that something is wrong with my phone, it drains the battery whether the phone was on or off!
Sending to the Collect Point for sure tonite after work.
Thank's a lot for you who read and answer my question.

[Q] Bricked Wildfire cannot power up

Hi
in need of help here....
The phone was happily running CyanogenMod 7.1.0.1 and all was well.
Had the phone plugged into the mains for a recharge and all was as expected.
However the next time that I looked the phone was off without any lights.
I disconnected the charger and tried to reboot the phone, nada
tried rebooting to recovery and again nada.
The phone is completely dead.
tried changing the battery with a known good fully charged battery,
Still cant boot the phone at all and interestingly when connected to PC via USB the PC doesn't see the phone....
Desperately need plenty of help here
TIA
Can you go into HBOOT?
see my post
http://forum.xda-developers.com/showthread.php?t=1401784
It details how to fix a similar issue i had
Doing it this way will totally wipe all your data i'm afraid.
If you cant get into HBOOT i.e. powers on but just a blank screen, let me know, i should have a fix at home (i'm at work at the moment)
Thanks for getting back to me,
But the issue is the phone is bricked ie cannot boot at all...

so no power to the phone at all? what happens when you connect to PC? does the charge LED come on?
No nothing at all, as I mentioned earlier no lights and the PC does not see it at all..any thoughts? TIA
Mmmmm seems like its a gonna mate.
Last attempt I'd try removing battery and leave it out for about 20mins,then replace and without turning it on or pressing any buttons plug charger in and leave for as long as you can. Try at LEAST 10 hours then try turning it on. Sorry can't think of anything else more to try.
" once its gone,its GONE."
Thanks for that I'll give it a try overnight and post back

yeah try that and ive just remembered something too but not sure if it was wildfire related but i think it might be worth a mention.
sometimes the chargers have faults and need replacing so lets throw that into the pot too. if the over night power down charge doesnt work maybe try a different charger as a final last resort. really hope its as simple as that for you cos to be honest its not a bad little phone to have.
regards slymobi.
Tried as you suggested, same result. Will try and borrow a known working charger but won't be able to organize it until the weekend. Will post back then.
Thanks for now and best regards Arfer
Ah gutted. Lets hope its the charger then mate. Could try a USB charge whilst you wait for mains charger. Just try off power charge from USB this time.

That's a good positive way to look at it ! Shame my wallet is now fully into it's own post Xmas "economic downturn"
I know this sounds like a noobish trick but I was in a similar boat today.
I ran out of juice today during school, so when I got home I plugged my phone in. Nada from it. Cut to the chase, I run CM7.1.0.1_buzz like you with CWM(2.5.0.7 I think).
Took the battery out, and pushed the white button in on it (assuming it's a reset button for the battery controller). Threw the battery back in the phone and plugged it in. I then had a red flashing light, which from what I've seen myself, just means the phone is completely flat (I've seen it twice and my battery still works, no replacement). So I'm leaving it to charge since last time I had it, a full charge got rid of the red flashing light to a solid red light (the normal charging one). I thought I had a brick too since I OC'd it since I rooted a long time ago.
Good luck!
EDIT: Forgot to add, I couldn't get in to HBOOT
Thanks for the battery button tip. Didn't work for me, have also tried putting in my mate's fully charged battery and it won't boot...the phone is no more

[Q] Need help

So I'm currently using the Suarom ROM, and for the most part it's been working fine. Suddenly I have a problem. Last night I plug my phone in to charge and suddenly it won't charge. I tried with two separate chargers.
It's still a new phone, so I can bring it in for warranty work. I just want to make sure I take all the steps necessary to "un void" the warranty. I'm a Rogers customer. If anyone can help I'd appreciate it.
Theres a thread in the DEV section that provides instructions of how to completely un-root and restore your device to factory before you turn it in for services.
The only problem is, my battery is at ten percent with no way to charge. The strange thing is that when I plug the phone in, the charging symbol appears. Just doesn't charge. Any idea why that would be ?

Tried different chargers? maybe plug it up to your PC see if you can get some juice that way? i can see the cable/charger going bad before the usb port on the phone ( but **** happens ) 10 percent should be good enough to get your phone back to stock though, i did it at 7 percent not to long ago, you just cant play around you have to click and run and get it done so it does not die. then if it dies after at least you are stock and can just turn it back in. but to be honest for a charger problem i VERY SERIOUSLY doubt they will be looking at Software and roms. thast a defect, and i think they will just do a clean swap----JUST LET IT DIE so they can not turn it back on in the store..lol
Ya could have a derpy battery and the phones fine.

Yeah, I have tried three chargers with no luck. Haven't tried a PC yet but will after work.
So if I'm getting the lightning bolt charging symbol, odds are it'llbe the battery rather than the port?
take it to best buy or an at&t store....and just say, hey i think i may have a bad battery do you have one i can use to see if my phone will power on and recognize the charger after it is plugged in. then you will know, unless you have an extra battery just laying around.
I had a similar problem like this before. Try charging with the phone off.
OR
If you want to troubleshoot and isolate the problem, try getting an external battery charger and a spare battery.
If you charge your stock battery and it charges with the external charger, your phone may be the problem. If not, then it's the stock battery.
And with the spare battery, try charging it via phone charger.
These are the possible ways I can think of at the moment. Hope this helps!

[Q] How to Repair a Dead HTC One X?

Hi All,
About a year ago, I bought an HTC One X from Three UK. I recently came to China on holiday and bought an external battery pack from a market stall. Everything seemed to be going well until one day I plugged my phone into the external battery pack and it suddenly died even though it was on ~50% charge, it wouldn't boot and it wouldn't charge when plugged into a power supply (no red LED shining). No combination of pressing buttons would work, so I decided to get it fixed.
I went to a repair guy in China who said that he would charge me if he could repair my phone, but no charge if he couldn't. He disassembled my phone but was unable to fix my phone. He said the problem was that the motherboard was 'burnt' (I'm not sure if the literal translation is correct), and that it would cost 70% of the original phone's value to repair (although he could be wrong about my motherboard being dead)
Now my dilemma is this: I'm not sure if I should send it to Three UK or ask another cheap repair shop in the UK. The problem with sending it to Three UK is I'm not sure whether they will repair it or not - my phone is completely dead and I don't know whether they will count that as improper usage. Also, now that my phone has been opened, will the repair center be able to tell that my phone has been opened before (I'm pretty sure I'm not allowed to open up the HTC One X) and then deny my warranty?
Thanks for any help that you guys can give me!

I haven't but I probably let it charge a while after my HTC One X died. Out of curiosity, why one day? It seems an awfully long time.
I'll plug it in now, and when should I take if off the wall charger? Also, what signs should I be looking for?

I'm hoping for a blast of life. I once thought I hardbricked mine, I left it in the wall charger and it booted up in the bootloader after being in the charger for a day. Reflashed my rom and boot.img and never have i had problems. I suggest trying to boot the phone up after a day or so, if this will not work try and charge it again and acces the bootloader right away. If you can access the bootloader you can flash custom software. Does the red LED show if you charge it? Can't you acces the bootloader at all?
Oh ok, so am I hoping for it to suddenly turn on or am I hoping that after a day or so I will be able to boot into bootloader?
I have not really used it or charged it since my phone died, but the red LED doesn't show if I charge it and I cannot access bootloader

Yes just leave it be, it's all the advice I can give to you right now.. Try it and if it doesn't work you can always get a replacement. This is a weird issue though, I also had a HTC sensation which behaved the same. Left it overnight on charger and it booted to bootloader, then I used a battery script to charge it up while it's restarting to bootloader.
Just leave it on the charger for a day or overnight, see if it turns on
The same thing happened to my previous One XL. In my case I flashed a recovery, had to reboot and the phone just "died". It wouldn't charge or turn on. Not even after charging overnight. It took a JTAG repair to bring it back to life.

Possible fix
Okay, so a while back I had this same problem. My phone turned off, and whenever I plugged it in to charge it did not seem to be charging, odd. The red light was not coming on either. I was told to do 2 things, i cant remember which order so try both.
Option 1:
Plug your phone into your turned on computer with the USB cable and leave it there to charge until the red light comes on (leave for 1-2 hours, more if you feel it necessary), then quickly put it on charge using the wall charger.
Option 2 (not likely to work):
Plug your phone into your wall socket with the USB cable and wall charger and leave it there to charge until the red light comes on (leave for 1-2 hours, more if you feel it necessary), then quickly put it on charge through your turned on computer using the USB cable.
If neither of these work (as dumb as this may sound)turn off your phone and put your phone in the freezer for 15-30 minutes (This is done to discharge the battery, wont break your phone). When you've left it there for your chosen time, try option 1 again. If that doesn't work, turn the phone off again and put it back in the freezer for the same time and try option 2. If they don't work, i'm sorry I don't know how to help you.

Thanks, when you say it booted to bootloader, do you mean you had to press some button combination and it went into bootloader mode or did you wake up and your phone just happened to be in bootloader mode?
Also, would opening up the phone void the warranty? Because, if so, I'm not sure I will be able to get a replacement.

Sorry I meant charging. I found it hard to believe that your motherboard was the problem, but if you're sure that's the issue then don't bother trying my suggestion. That really sucks man, how'd it happen?

I think everyone is kinda missing the point here, the OP made reference to an external battery pack from a market stall which seems to be what killed the handset. Coupled with the fact that a seemingly reasonable repair shop, they didn't charge any money, said the board was dead I think it's safe to assume that the external battery pack was the wrong voltage/amperage or it was faulty. And just in case you do try to charge it, on the slim chance the shop was wrong about the board, it's no good charging on your laptop, you need to plug it into wall charger.

Yes, thank you so much, you are the first person to pick up on that!
I did leave my phone plugged into my laptop for a few hours, but no red charging LED. I also left my phone plugged into the wall charger overnight, but also no red charging LED. Does this confirm my fear that my motherboard is completely dead?
The guy I went to seemed reasonable, but he didn't seem 100% reliable. He didn't have a manual of the HTC One X up on his computer screen or anywhere, he just went straight in, although it might just be me being the skeptical one. I would say I don't completely trust him, so should I go to another cheap repair shop in the UK or just send it to Three and hope they don't notice the phone has already been opened?
Thanks,
~DarkEddy
Anything is worth a try if it isn't going to cost you money, although I must say I have seen a number of cases of external battery packs frying boards. I would say three would be your best option if it's still under warranty, but the there is a screw inside that has a seal over it and if that screw was removed then they will notice the broken seal, unless they are blind. They look for things like that so they can get out of repairing handsets free of charge. If the phone is dead you don't really have anything to lose. The only other option is sell it for parts

When you say you've seen a number of similar cases, do you often repair mobile phones or as a job?

This is your second thread on this issue, why not continue in the other thread...I reference http://forum.xda-developers.com/showthread.php?p=44370602#post44370602
To answer you dilemma directly, send it to Three and play dumb as a post. You have no idea what they're talking about...did they sell you a refurbished phone? You're outraged, blah blah.
Or you might try going to HTC directly.
With either or, I would simply leave out the details. You plugged it in to charge, which you did, and it just died. Poof. Gone.

I suppose I should have continued in the other thread, I just thought my post was a bit cumbersome and overloaded with excess information.
Three did send me a refurbished phone when they weren't able to repair my previous HTC One X, but I'm pretty sure they would have tidied up the internals as well (adding their seals)??? They even sent it to me with some blue plastic tape covering the back and sides of the phone.
I could try going to HTC directly, but I suppose it would be more complicated than just asking Three, so I'll do what you said and hope for the best

Xperia Play red light

Hi,
yesterday I bought a used R800i, the seller said I just need to charge the Battery. So back at home i plugged it to a charger an the LED near the power button startet blinking. First I thought it´s not a big deal but after a couple of hours it was clear that this is not alrigt. Even if i remove the battery the red light keeps blinking continuous (not 3 times or something similar, just every second once). I don´t know if it´s a software or hardware bug but could you help me to get it fixed?
best Regards
Lukas
It could be empty battery (but voltage level is not high enough to start charging).
Check with flashtool can you enter flash mode or fastboot mode (if you can, then it's probably empty battery)
If you can, check voltage level of battery with voltmeter.
It can be that motherboard is dead, but to be sure, you must know what is voltage level of battery.
For now, try leaving it charging, it might take some time (few hours or more) to actually start charging...

If battery have 0 volts then it's dead and (most likely) can't be charged anymore. You need new battery, so you can know is motherboard is working or not.
But that is just my opinion, and i could be wrong...
Maybe to try and charge battery from external source of 5V power , easiest way is cut some usb cable or take two wires from PC's molex connector (red is +5V, black is GND) and charge it for shortly (about 30sec-1min) and measure does it have at least 3.2V. Repeat short charging untill it does. If it stay on 0V then is dead for sure.
I was really able to charge the battery over a cut USB cable. I got it to boot until lookscreen (digitizer does not response) but then the battery turned hot and the Xperia shut down. I ordered now a new battery then it should work again

Digitizer not working could be faulty slider-flex cable or simply software error due overheating. You'll know with new battery...
Flex Cable looks like this, should I get a new one?

Yes, that's slider flex cable.
But wait untill you get new battery. Then you'll know does it have more problems or it is working normally
Sad News, today I got the new battery and i was even able to boot up the phone, but like the last time i was able to boot it up the battery and the mainboard got hot. I think the loading circuit is broken. So there are two options 1. buy a external charger for the batterie or 2. sell the phone as rarely used on ebay
No really I´m selling it, even if i get a charger theres also the problem with the not working digitzer. Thanks for your Help but this is ways to big for me.
Regards Lukas

Sorry to hear that. Obviously problem is much bigger and hard to tell what is wrong without some proffesional look into it (lot of reasons for phone to get hot by itself - there is short circuit somewhere and that's why it's draing battery fast and causing overheating). I don't think external charger will solve problems.
Anyway, good luck :good:
