Hey guys, I got a real big problem.
I've got a Rhodium100, but it won't charge nor it'll boot.
When connected to original charger or pc the phone starts. Then I can see the HTC logo and it dies again. The battery seems to be totally dead
What I've triend so far:
1. Pulled out the battery
2. Multiple cabels for the charger
3. Soft reset
4. Hard reset (won't complete because the battery is dead)
5. Checked the on/off button (on top)
What else can I do to fix this problem? I'd like to try anything before sending the phone to HTC (did that 2 times before, but with other problems).
This is what happens: MOVIE
Thanks in advance

Buy a new battery and see if that helps. There are some cheap ones on ebay.
I just found another cable and it seems to be he's charging again. But after 5 hours of charging it's still on 40%.
When the battery-level is around 45% it goes downwards to around 38% and then to 45 again..
This is circulating..
How can this be?
You shouldn't let the battery completely die in the first place. A deep discharge of any Lithium Ion battery is not recommended because of this. If you've tried to do a hard reset and it did not complete, you may have destroyed the ROM image. If it doesn't turn back on, flash a stock ROM.
Always try to charge the device before it gets to 5% remaining battery. 10% is recommended, but 5% is the lowest the battery should ever be. Having a second battery is always a good idea. I have two of them and an external battery charger. This way, I can always have a battery able to charge without needing the device just in case something goes awry.
Make sure you do not turn the device on. Leave the battery in the device overnight on the charger without turning it on. If it still does not function after this, you might try purchasing another battery and charger.
If you have time left on your warranty, this is covered by it. Simply call your carrier or HTC and they will fix it for you. It's generally faster to go through your carrier if you have the option to do so.
Thanks for the tips. I followed them and it seems to be my phone is fully working again!

I have the same problem since august 2010. I've do the same as you flashing some ROM's also restoring original one(T-Mobile), buying new akku ang external charger- but nothing helps When I place battery in phone it switches on by self(seems like power button abridget but I've checked it with testing device), starting showing T-Mobile logo "Stick together" then shows windows logo then backlight fading then device restarts, so it happen infinite till battery fully goes empty. Now on phone is installed original ROM and I can't install any other- in bootloader I can install only SPL's, but other ROM's not installs (flashing process freezes on 0%). I haven't any ideas, somebody can help me? Thank you all.

It's a dead battery. If it powers on by itself, then you'll either want to get a new battery or an external battery charger. Make sure you're charging from the wall, and not a USB port.

Yes, I do as you suggest - bought new battery and wall charger, but no result. I doubt that new battery or charger is destroyed, but anything is possible... What actually kind of problem if phone couldn't do hard reset, not upgding ROM, also switches on when battery is placed into? 100% fault (discharged) battery?

I mentioned that you may need to charge the battery externally if it is powering on when you insert the battery. You'll either need a friend's phone to charge it, or buy an external charger. With the external charger, let it sit on the charger overnight, pop it in the phone, and then try again. If using an external charger does not work, then you may want to send the device in for repairs/replacement.
Today I had my One X happily connected to my pc, just transferring some files over by USB. Then when I wanted to disconnect it, it showed a lot of 'not getting enough current to charge and operate at the same time' messages. Dismissed them all, though it was time to put it on the wall charger, seen it's critical battery status.
Once I disconnected the phone, it immediately powered off and would not come back to life again. It was, however, greeting me with a flashing red light while on the wall charger. No matter what I tried (bootloader, long hold power button, charge it for some time), it remained completely dead.
Now I did get some new micro usb cables from eBay. Very cheap ones. Now I think these are the culprit. Apparently, while in file transfer mode, these cables were unable to provide sufficient current, causing the phone to drain the battery completely. Once I wanted to charge it, it couldn't boot to charger mode due to the battery being completely empty.
Hooking up with the original HTC cable again, it still showed the red flashing light. Exact same behavior. Until I (for the heck of it) tried to bash the power button quickly. It suddenly came back to life again and started charging again through PC.
If you find yourself in the same situation with bad USB leads (something to do with resistance of the cable?) or a red blinking light, try tapping the power button quickly instead of trying to boot into recovery mode. It might save you a postal return and a week or 3. Or your ass, if you rooted it before it stopped charging.
When I had my sensation I had this every now and then. I had to remove the battery to get it to work.. Nice to know that there appears to be something I can do to sort this out if I get this now

It was mentioned that the flashing red (or orange?) meant that the temp was too high.
Just let it cool down, and it will come back.
It definitely wasn't hot. Also, it wasn't flashing orange. Just slowly red.

flashing orange - low battery
flashing red - very low battery
It could well be the battery level is considered too low to operate. So to protect the circuit and the battery, the device is not allowed to turn on until it is sufficiently charged.
This is currently (no pun intended) happening to my one x, left it plugged into my pc via the htc usb and got flashing red light after a couple of minutes, after a couple of minutes more it stopped flashing and became a solid red light (a sign it is charging from v low battery from m experience) pressed the power button and voilà its come back on. I can't believe htc would let the device get to such a critical state of battery before powering down, can anyone enlighten me as to why it would do this?
(thinking about it i was showcasing the handset to my apple touting buddy and had 3 pretty heavy apps running, it was a couple of hours after i noticed it had killed itself so i'm guessing they were still draining away the power from the background??)
I'm having the same problem. My phone was off when i got home and it wouldn't turn on (I assume the battery was dead). When I put it on the wall charger the red the red light didn't turn on and my phone wouldn't boot. I tried several chargers and cables and also tried to connect it to my pc. After leaving the phone for a few hours (unplugged) i tried to connect it to my pc again and i got the blinking red light. A few minutes later I decided to plug it into the wall and the red light turned on and now it is working normally.
anyone got an idea why it didn't charge at first?
agree chaging cable fixed my flashing red light problem
Poor quality charging/data cable
A poor quality charging/data cable will also impact the ability to charge the HOX in your car. I have two cars, in one I was using an old Blackberry cable and Griffin charge adapter (1amp output) to charge the phone whilst using Car Dock and navigation software. After trial and error I got the screen brightness correct and the phone charged satisfactorily. I say satisfactorily because I still think any electronic device which is connected to an external power supply of sufficient electrical current should operate and charge at full spec. In my other car (1996 Land Rover Discovery) I was using a cheap ebay charging/data cable. Using the same apps and screen brightness the HOX would lose all charge over about a two hour period. With the same Blackberry cable used in my other car, no problem. Hence the cheap ebay cables are now in the bin.

The HTC-cable isn't that good too. I use a Nokia-charger to charge my HOX. Charging is much quicker. Maybe the HTC--charger (and cable) was crappy but i never touch them, i use the Nokia charger and dito USB cable.
Thank you!

thank you! Thank you! That cheap usb was totally the problem!
Small update.
This problem just happened to me. 1 cord gave me flashing red while plugged into the wall and pc. I switched to my other cable and its charging and functioning normally. Cord was the problem.
I had a similar issue with my one x.
It discharged completely, then when I went to charge it I just got the red blinking light for ages. I left it charging overnight thinking the battery was so low it needed a while to charge enough to be able to switch on.
But in the morning it was still flashing and the phone was very hot, so I thought the battery was blown.
So I came on here and saw a suggestion about holding the power button and the volume down button. It went to the boot menu and said there was not enough power for a factory reset or something, so I selected recovery. I then got a warning icon and the phone switched off again, but this time with a solid red light. A
After a while I was able to turn it back on again.
Hope this helps.
Wellllll
I have the HTC One VX. I know this isn't in the same topic, but since I found the thing that helped/worked here, I thought I should share my experience. So I bought my new phone on Sunday, so it is roughly 5 days old...not even a full week. I charged the phone before I went to bed to roughly 80%. I made sure all apps and what not were turned off and pressed the lock button. I woke up in the morning and checked my phone to see what time it was. Had 78% battery left. I left it on my dresser for roughly 2 hours and when I got back from class, I grabbed my phone to check if I had any messages.
The phone didn't turn on and I didn't even get the flashing orange/red light. So I tried charging it and nothing. I changed wires and nothing. I frantically searched the internet and stumbled upon this forum/thread. I tapped the power button at least 15 times consecutively and the phone barely flashed orange. I tried to plug it in again and rapidly pressed the power button 10 more times and the screen finally turned on. It started charging and I checked the battery life. Somehow, in 2 hours my phone drained itself of 78% battery life when it was on the lock screen (its also set to lock after 15 seconds of inactivity) to the point where it couldn't even turn on.
The phone/battery was not even warm/hot or w/e. It had not touched any water. No idea what caused the immense power drain, but glad it is working. Thank you so much for this help
woops, wrong thread
It happens to me allso in this morning, in my opinion is like this: The phone is turning off when basicly you have a little bit batt (lets say something around 5% max) and its turning off to protect data and is showing to you batt empty. Then it cames a user with a charger connected to a power supply (house charger,car charger or directly to pc's usb). You must use a good usb to micro-usb charger (the original ones are't good usb cables) try to use a Nokia usb to micro-usb cable, This was the first problem most usualy. The second one is to pay a HUGE attention to UC, don't uc'it so much because then the charger board will not charge your batt so well. Keep yours HOX safe and anjoy it. Have a nice day boys and girls.
A few hours ago my phone started emitting beeps as if some notification was turned on (I have all such off). I have not paid much attention, as the beeps eventually stopped (!!), except for when noticing, a while later, that the phone - albeit plugged in and with the battery indicator showing "charging" - the percentage was decreasing. I watched it for a while, and the batter was discharging while plugged in. Did the followings:
- replaced the battery with a new/charged one (my spare) - same behavior
- replaced the cable with the original samsung - still the same problem
- tried wall outlet charge, laptop charge (via USB), etc - same problem
The questions for those having experienced such:
- would the beeps be indicative of a problem, or just coincidental???
- the phone is definitely the culprit here - the question is if there is something that could be done for some sort of cleanup of the port, or improving the connection (seem to recall some such from a site - maybe this, maybe another forum - could not find the article by searching), or further tests I could carry out, before I take the phone into the repair shop (which I am not sure if there is such in my area)
TIA,
Stefan
can your phone charge with the phone off? Turn off the phone and then plug it in, do you see a big battery icon charging? Also is your phone rooted?

Upon turning the phone off and first plugging it in, it depicts a grey battery with a non-spinning wheel in the center. After approx. 10sec the screens starts showing a semi-filled with green battery, with a scrolling bar of dots underneath it (active this time, unlike the wheel described before).
I am sure that everyone knows what I am talking about, having seen it many times before, even if my description is not that good. The issue is that I have never paid attention to this part - mostly because I almost never had the phone plugged into power and not immediately turned on.
Observation after doing the above: after having left the phone off for almost an hour, the battery charge decreased (84% -> 80%) while the phone was plugged in.
NOTE: When the charge was 100%, by using a battery I charged with an external samsung charger, I also re-calibrated the battery using the app (phone is rooted, but always using the stock ROM). Just FYI - if that matters.
Thanks for any [ongoing] assistance.
ok if your phone was off and plugged in, and was still losing charge then I'm not sure what to do, sorry, hopefully someone else who has experienced and solved this can help you out.
my issue was similar to you where i couldn't charge my phone while it was on, i could only do it while it was off...it was a software issue, so i flashed the stock ROM, started from scratch and everything was fine from then on.
if you havent already, make a back up of all your important data (msgs, apps, etc.) download a stock rom (http://forum.xda-developers.com/showthread.php?t=2276645) and flash it, maybe that might solve the issue
The beeps may have been the phone detecting the charger on then off multiple times. Check the charge port on the phone for any breaks or debris.
Otherwise I dont know what to tell you aside from try another cable and charger. Sorry.

Hello all,
I'm at my wits end to put it lightly... I have the P-605, I was trying to flash ng1 official firmware through Odin v3.09, which the file in question, I have used a few times before so it isn't a bad download.
It got about half way through and died. The tablet still boots to the 'firmware upgrade has encountered an issue screen', I can still enter download mode. One major issue I can't charge it and i have no recovery [emoji22] its now dead flat.
Even with my 2.1Amp tablet charger it boots for a few seconds and dies. I've tried multiple cables and USB wall chargers as I thought that may be the issue all to no avail! I am completely lost. Any help would be muchly appreciated
What was the firmware before you flahed the stock ng1? cm11?
Have you try to flash recovery with Odin, don't let it boot up and see if you can boot into recovery.
Did you try to flash with low battery juice??
The prior firmware version is unknown :-/ but it was X KAT v3. I did try to flash recovery but it resets before it gets it done, if I hold the PWR, VOL+, HOME the screen seems to light up stay black a little longer than if it was going to the firmware issues screen then go to 'firmware upgrade has encountered issues' screen. It seems the longer I keep it off charge the longer it takes for it to reset next time its plugged in, so I will leave it for a hour and try to flash recovery. I didn't know what the battery was at 'probably very low' as I haven't used it in yonks and it was already in a bootloop from flashing X Kat v4.0 incorectly otherwise I would have charged it
I'm thinking about taking the battery out and manually charging it with a old USB cable. From pictures on the internet the battery has 2 red 'positive' 2 black 'negative' and 2 green. I'm unsure of what the green cables are. Is there anyone that can shed some light on this?

Hi,
have a look here for the USB pinout !
The original cable uses only four of the micro usb pins. The second ground pin is missing. This can be used to put the device into certain modes. I used different cables, all with five pins, no problems, but it does not mean, that the fifth pin was wired in these cables. Batteries have an internal security circuit which cuts power vis a polyfuse, if the voltage drops too low. The fuse should be re-armed when connecting the device to the charger, although the device may not recognize its own battery. Let it charge for a while, that the fuse doesn't blow again when disconnecting. Plug in again to charge fully. Some devices have a design fault which makes them unable to recover with a discharged battery. Charging Voltage is not 5, but 3.7v! The additional cables at the bsttery are either for a dumb temp probe, or a bus to communicate with the security circuit. The latter maybe impossible to charge externally. Otherwise you probably need some professional charging station, which can handle all sorts of Nimh and LiOn batteries AND have to make an adapter for the custom battery plug. Too much hassle, right?

Get one of this usb filter charging adaptor and use your pc to charge it. This also allow you to charge your tablet using any power source like PC, car charger etc... you will not see the X mark when using your pc to charge.
http://www.amazon.com/gp/product/B007IXBTCK/ref=oh_details_o02_s00_i00
This adaptor adds Apple signaling for charging currents above 0,5A. If the current charger won't support Apple stuff.
And yes, I suspect that the Note expects the Apple signal for 2A iPad charging.
I don't know whether there are any supported charge modes in between, like 900mA, but it charges from a standard 500mA usb port, but only in soft-off and idle deep sleep, and ultimatively slow.
But then, since the KK update, some people's Notes charge only during active state.

I have the same issue.........!!!
I'm lost at this point and dont know what to do.
Any attempts at flashing appear to be useless as there is now zero battery and it wont charge.
It boots straight to 'Firmware encountered a problem screen'. I can get it to the download screen.
It also made it 47% of the way through a recovery via kies, but i think the battery issue caused the failure.
If the cable is pulled out while in the firmware encountered a problem screen it instantly dies and wont start. It wont start unless the plug is in........
Anyone??? Please???
With zero battery, you can't perform any maintenance requiring a usb connection.
Without OS and/or custom recovery, i don't know any advice.
ADB and probably Fastboot operations can be performed via wifi, while the thing is at the charger, but in brick state this won't help.

Maybe the Note froze and drained the battery till it's safety circuit kicked in.
Then you should leave the Note charging for a while(hopefully), to reset the circuit's fuse and get enough juice to not trigger it again immediately. Normally, after unplugging and replugging, the battery should get recognized again and charge normally till full. Monitoring charge in Off-State requires(only) a working kernel, i think.
It also could be a defunct usb jack or just the connection with the main pcb is loose, which is typical for the Note, like loose display and backlight cables.

Thanks Lecorbruiser.
I have had the unit aprt a few times to verify battery connections and all ribbon connections on the boards are ok.
Im note sure of the safety circuitry uou mention though.
I have also power the device up with out the battery plugged in at all. So i know the supply is there. Maybe i have run the battery too low to recover?
Sent from my SM-G900I using Tapatalk
The safety circuit is in the battery or attached to it. Once its fuse has been triggered(normally at 2,5v), the battery shows zero voltage & open circuit. Current from a charger should reset the fuse and the battery will charge unless it had been discharged below 1,5v.
Normally devices with 3,7v batteries are shut down by the system at 3,5-3,0 volts, mostly 3,5 like the Note.
Well the device started to flicker and couldn't keep the screen back light on when it go low.... I'd say I have trashed the battery then if it got below 1.5?!
I have left it on charge for over 10 hours a couple of times and achieved nothing
Android shuts down at 3,5v, in case of a freeze(which could go unnoticed if it happens in standby) the circuit at 2,5v. Then it's a matter of self discharge, till the battery reaches the critical point of 1,5v.
The flickering backlight denotes one of the other cables running across the battery, like that for usb.
I think the connections loose by holding the note in your hands, pressing on the backside. A case with a stiff back will stabilize the Note, like mine. Otherwise all pressure goes thru the flimsy back and is applied on the battery, the metallic shields or some spacers. And the cables get bent very slightly during pressure. Should be harmless, but seemingly isn't.
I have done some testing... here it goes:
Battery Voltage disconnected 2.69V
Battery Connected and USB connected 2.8V
Battery not connected or ( after accidently) shorted 1.5V
From my reading android min voltage is about 3v?
Normal voltage from 3.7v to 3.2V and Charging voltage at a max of 4.4V
I also see some talk of 2.7V figure as a minimum cutoff point, this maybe why it will not give 4.4V to charge as below 2.7v maybe considered a write off?
Thanks for your info lecorbusier
With some custom roms, but none i know for the Note, you can modify the shutdown voltage, to squeeze out a couple of minutes battery life, though the voltage goes down rapidly after having reached 3,5v.

Thanks for all your help.
I purchased a new battery and did a normal kies recovery and it's back from the dead... Thanks again

Hey folks,
I did not use my tab for several months (it was working before), now when I plug it into the charger (either usb or wall socket) it either hangs in a flashing screen sensation of the Samsung galaxy tab pro screen or at the battery screen while this one is just with a loading icon, it does not really charge.
As soon as I unplug the cable it shuts off. I cannot boot into recovery mode, it just hangs there. I can boot into download mode however and I re-installed root and twrp recovery via Odin, however this did not help.
Any other suggestions please?
Appreciate the help.
Plug it into the wall. Leave it plugged into the charger. Hold the power button down for up to 2 minutes. See how it goes!
No change, just keeps rebooting.

When you didn't use the tablet for those several months did you keep it running or did you use the power off option, if you left it running then it probably shut it-self down when battery got low, then the extra time left probably completely depleted the battery causing irreversible damage to the battery (lithium-ion batterys aren't made to deplete to 0 volts it will ruin them), the proper way to store a battery device is to fully charge it then power off the device and it should store for up to a year fine.
sometimes you can give the battery a boost, or maybe the samsung charger blew out, first try another 2+ amp charger and a new cable.
or you can even try your pc usb port connect it for about 10-15 minutes (sometimes the low 500mA current is good to revive completely dead batteries though keep the screen off), see if you can get any voltage back into the battery and if it starts holding a charge, then switch to a proper charger.
if the battery is under 3v the tablet is designed to shut off to protect the battery so if the voltage is less then that it might take some tinkering to get the voltage above that threshold to keep the tablet running.

I'd guess it was left off without powering it down.
When I plug it into the PC via USB or into a power socket I just see the 'Samsung Galaxy Tab Pro SM-T320' log and it is flashing continuously.
RMA? I can get into download mode, but how does that help me? Knox warranty void shows 0x1 - it's voided, correct?
Anyone?
hello
your battery is hs
look here to change it: "https://www.newpower99.com/"
when you leave back your tablet use these: "repair battery life" & "L speed"
regard
thanks
can anyone vouch for this shop? I'll order a battery there and try to repair it myself.
that worked, easy installation and extended battery life
