got an SDA with no prior knowledge of its history other than "it wouldn't power on" well when I got it the battery was completely dead "0 volts". Since I didn't have an external charger I did a little work to my external MPx220 charger "uses a 3.6v LiIbattery" to fully charge the SDA battery. I put it in and tried the key sequence to get the bootloader to appear.. no go. Tried camera button while I plugged in USB with and without battery.. nothing. So I left it plugged in while I was searching the forums last night for more information the screen turned white and all the keys lit for about a minute then it turned off again.. and I haven't been able to get it to repeat this since.. is there any hope at this point? Thanks!
now I'm confused.. I've seen yet another method for entering bootloader on the Tornado's http://wiki.xda-developers.com/index.php?pagename=HTC_Tornado the camera + botton on opposite side and power.. this doesn't seem to work for me either.. but which one is right? does the battery need to be in or out? usb plugged or unplugged.. I can't believe this device would be so "dead" as to not do anything at all.. will T-Mobile honor the year warranty of these new phones?
Is this model just so new that not much is known about it? I'm surprised that I haven't gotten any type of input yet.
the same problem
hallo
i have the same problem, please if you have found the solution, tell me or send me an E-mail [email protected]
To me it seems like the battery is not charging at all. I've seen this with Motorola Li-Ion batteries. Unless there is enough amperage in the charger, the battery won't charge, regardless of what it looks like. If you really want to go forward with this, one idea may be to get an actual SDA charger, or replacement battery.

Or maybe a Motorola charger? USB cable is 5v, Motorola charger w/USB connector is 5.9v. Motorola phones can charge from PC USB port/hub, but only if the phone is turned on. If phone cannot be turned on because the battery is dead, you need the wall charger...
To whom it might concern,
I have been struggling here in Egypt to fix my Nexus S phone, I purchased the phone from T-Mobile USA and It’s not anymore under warranty. I sent my phone to a couple different Samsung service providers here in Egypt, but the problem is that the Nexus S not a popular phone in the Egyptian Market and they couldn’t fix it for me.
The problem started when I first left my phone over the night charging and I went to sleep. I woke up in the morning and the phone is only at %30, I can’t charge the phone whether by using a USB or wall adapter. My phone is currently dead and one last thing to be mentioned is that when I connect the charger I only can see the power bolt symbol but if I go to the settings of the battery it does show “Discharging”.
Thanks in advance, any help will be very much appreciated.
Well I'm no expert but I had the same problem but with my battery for my laptop. Even plugged in it said Discharging so it might be the battery. Sounds plausible since you see the bolt or it could be something with the hardware with a bad connection between the battery pins and the NS pins on the phone.
But as I said I'm no expert.
Maybe it's the usb charger port of the phone, having the same issue here! Though not as extreme as you, I ordered a new charger port but I have yet to put it in, think I will bring it to an expert in soldering. Also, you can buy a battery charger on ebay so you can at least charge your battery.
I also would like to mention something extra, I did buy a new battery like a week ago. I install the battery, the phone finally turns on, battery shows around %60 i try again to connect different chargers or even my usb cable and again the battery status is "Discharging" and i see the bolt symbol. I try to turn off the phone and take out the battery and turn it on back, again the battery drained so fast to around %50.
how possible can i check if its a faulty usb port?? and where can i find it online since this phone is not in the egyptian market!!!

Well I don't think it's the battery, sometimes when you pull the battery and turn it back on there will be a jump, don't know what causes this, not an expert. You can check wether it's a faulty usb port by trying different/new cables. If you wiggle the cable around a bit do you see any change in status? If it's not the cables, did you do anything software related? I've found that coming from ICS rom to jelly bean it got a bit more responive to my cables (maybe plasebo).

Hi everyone,
My first post as I haven't been able to find an answer. My Photon Q was probably about 30% charge when I last checked with it on. An hour or 2 later it was a little warm and was off. So I went to charge it using the car charger with 500mah charge rate. I came back about an hour later and the phone was really hot and no charging screen so I unplugged it. The green led light is lit when the phone is plugged in.
I tried holding the power button and volume down button, but it won't boot. If I have the usb charging cable plugged in from a PC or charger adapter when pressing those buttons, the green light will flicker off for a fraction of a second.
I then proceeded to dismantling the phone as I suspect a battery issue and the one in this phone is stupidly non-removable. After taking the back cover off, I tested the battery posts and received 0 volts. I still don't know if the battery caused the drain or if there's a short in the phone. I then took off the inside cover that holds the battery in. A few T5 screws later and the battery was removed. I connected the battery to some AA batteries in series to see if I could get a charge. A few hours later I got it up to 3 volts which held for several hours. So I connected it to a few more AA batteries in series to try and raise the voltage. I got it up to 3.67 volts and the battery is listed at 3.7 volts.
A day later and the voltage is still at 3.67 volts so I put the battery in the phone. I went to try and power it on, but nothing. I then connected it to a usb cord and received the slow flashing red led light a couple times before switching to green. The battery started getting warm again connected to the usb charger. After 20 minutes it was approaching hot so I unplugged the USB. The battery read 3.54 volts. 30 minutes later, 0 volts again.
Does anyone know what the actual voltage range is for this phone, as my old Samsung M320 is also 3.7 volts, but when testing the battery I get 4.10 volts? I heard it's pretty specific on minimum voltage. Any ideas for a temporary battery or way to boot the phone before spending $50 on a replacement battery and then find out there's a short in the phone. Is there another key combination to boot the phone, I'm trying to boot it to at least get my pictures and other data off it.
Thanks a lot in advance
Matt
Not the battery, seems to be an electrical short but where
I bought a new battery for the phone which had a 0 volt charge when I received it. I tried putting it in the phone as is to use the phone charger to charge it, but got nothing. So I charged it using 2, then 3 and then 4 AA batteries in series to get it up to 3.7 volts. I then put the battery in the phone and noticed the 2 large chips and the chip centered above them located by the camera get a little hot. I tried with the charger connected and not connected, but same thing. Power button doesn't turn the phone on. Just the green led lit when the USB power cable is attached. So now it seems there must be a short in the phone. Anyone know where I can look to check for a short, blown resistor or something in this phone? Or at least where the rom chip is located so maybe I can turn it into a usb drive to get my data at the least.
Anyone? I still haven't been able to find a solution. I don't see pins touching, but if some pins are touching in the usb port, would that cause the heat issues when I put a battery in that I charged externally? I do get the green led light when I plug the phone in to charge so figure that means the usb is ok?

did you try a other charger ? do you have oryginal photon charger ? for me its not a reason of battery
regards
(in situation like that charging with normal usb cable when you plug phone to pc dont charging battery, you need motorola usb service cable to make it work)

Yep used the motorola cable that came with the phone (plugged in the wall and just the cable in multiple computers, another motorola house charger (the same as the one that came with the phone), a motorola car charger, and a samsung house charger.
When you say motorola usb service cable, I assume you're not talking about the motorola cable that comes with the phone? What usb service cable are you referring to?

factory / sevice cable ( i make my own from below tutorial)
http://forum.xda-developers.com/showthread.php?t=1077414
if you buy / make this cable , you will be have posibility to use RDS lite and flesh firmware this also make help (if you have low battery flesh with normal usb cable is not possible )
and second thing... maybe try some car charger ?
Hello guys, i am hoping that you can help me because i don't know where else to turn. I purchased a Verizon note pro 12.2. I was using it and on for about two weeks until i got my surface 3. Two days ago i went to use it and it wouldnt turn on. I assumed it was the battery so i put it on the original charger for about an hour and attempted to turn it on. It booted to the Verizon logo then flickered off. I put it back on the charger overnight thinking that would fix the problem. When i attempted to turn it back on it loaded to the Samsung splash screen and then turned off again. When i plugged in the charger once again the grey battery icon came up saying the battery was 100%. Even with the battery saying it was 100% it still wont turn past the splash screen. This only happens when it connect to the charger. it doesn't do anything at all if it is not plugged in. I have taken the battery out and reconnected it... still nothing. Looking at other post i assumed it was a software issue so i tried to sideload a stock version (Cant use odin because the tablet cant even boot into odin mode) of P905VVRUANK1 which is what the tablet was running. I got the error footer is wrong security authentication failure. I dont know what to do. Please help!!
correction i did not sideload (wrong terminology) i tried to flash through recovery mode.

Probably you have a loose or cracked battery connector. Try this, power on while pressing hard on the back near the center ( location of battery connector ). If it can boot this way, you need to re solder the battery connector.

I have tried this but still nothing. I also switched out the battery with another note pro and that tablet powered on with no power. when i tried to use that battery in mine i still got the same result.

I have seen this problem in many Tab Pro or Note Pro: it cannot turn on even with full battery. When battery connector's pins are open or cracked, your tablet won't be able to turn on. There are too many unknowns such as USB charging port, battery connector, or battery. You need this tool to find out where is the problem:
http://www.ebay.com/sch/i.html?_fro....TRS1&_nkw=usb+voltage+current+meter&_sacat=0
When charging, current should be 1.7 Amps.
It sounds silly but I see many users cannot figure out the problem which simply comes from bad USB cable or charger or USB charging port. This tool will eliminate guessing.
Since checking battery connector requires experiences to know the solder joints are good or bad. My recommendation for your problem: Re solder the battery connector if everything else: USB cable, charger, USB port, battery are in good working condition.
Use another battery you won't see the difference if battery connector on main board is cracked or loose.
Cracked battery connector is very common in this tablet but most average users won't see it or don't understand why it's the source of problem.

I do not believe that is the issue. the charger i used after the fact was a samsungng 5.3v charger thats belongs to the other note pro. im assuming if it was a issue with the amp that the other note pro would have the same issue... could it have something to do with the bootloader maybe.... or maybe theres a file i could flash that im just not aware of...

Beut was right all along...
Hi, I am a novice in phone repairs though I have successfuly replaced the screen and charging ports on a samsung s6 and note 4.
I am requiring some expert advice on this problem, I was given an XZ from my friend with a cracked screen and charging problem, the charging port became temperamental and failing (at least I think it was that) and eventually wouldn't charge at all. The charging port was handled a bit harshly toward the end, for example the charging cable lifted up and down to try to get a charging response.
Anyway I ordered a screen/digitizer and charging port flex for it, and fitted them, following a guide. Before this, the phone had around 2% charge. After the repair, I switched it back on and conncted the charger, the screen was fine, however there was no response from the charger. The phone then ran flat and eventually ran flat enough to not be able to show the "low charge" symbol when the phone is off. Then after plugging and unplugging the cable (via USB in the pc) it would charge for what seemed a second then stop, the red charging notification light was lighting up. The same happened with a wall charger. I then stripped it back down and back together again. This time there was no response if I remember right, then I connected it to the wall charger and left it for 3 hours or so. I went back to it and it had charged up to 15%.
Now i'm at the point where the phone is working, it's on 90% now, but it charges very slowly, around 60-350 mA per hour on Ampere app. So a full charge is around 12+ hours. This is in the wall socket with a fast charger. Additionally, it takes 10 seconds for the phone to recognise the charger after is is plugged in and that is consistent each time I plug it in. The phone now isn't recognised by my PC via USB, and also won't charge that way also, it just doesn't do anything if I plug it in there. Other than that, the phone works and it holds its charge well.
Any ideas? Thank you.

pick up an original sony charging cable - no idea why it makes such a difference, but.........
Hi, thanks for the reply, I bought a sony charger but it's still the same, drawing about 50-300 milliamps from wall charger, not recognised by PC and takes 10 secs exactly for the phone to recognise it's being charged. It's just odd how it stopped charging before the "fix", now the new flex lets it charge slowly. Can a battery problem cause this? It still holds its charge well. Maybe this problem is recognisable by some phone repair experts around here? any ideas?
Thanks
Noticed the phone only draws charge from a 3amp charger, anything less isn't recognized. And the power drawn from a 3amp can be 30-1000ma but averages around 300 ma. Can anybody point me to a hardware forum maybe? I can't find any, i guess it need taking to a phone expert but it's gonna end up costing more than its worth with the stuff i have done already.
Aukey Quickcharge 3.0 is working fine. It is cheap too.
I have just purchased a aukey charger, but my XZ seems to be taking longer to charge than the UH20 charger that came with my XZ. Any suggestions guys?

Buy a UCH20
Sent from my F5321 using XDA-Developers Legacy app
Have you tried cleaning/replacing the charging port itself? As i see, you replaced only the flex cable.
There's probably extremely weak contact somewhere in the charging hardware i think, because you need 3.0 A charger to get any kind of charging response. Weaker current probably gets lost at that 'weak contact'.
Buying new chargers won't fix that if you ask me
I have exactly same problem with you
I am about to buy a new charger, yet I saw your post
At first I thought it was the cable. Then my cable work normal with other phone. So does my charger, it connect perfectly with other phone (xperia xz premium and xiaomi mi5)
It seems that our phoneis the only one who can'y charge normally.
I am quite depressed, also looking for solution. Mind if you share if you have succedeed? Thanks before

Try plug in and plug out. My phone sometimes charge a normaxl. But need a lot of effort
Solved
Use the the detect usb in the notification keys before connecting the charger,, this will solve the fast recharging issues
Did you solved problem? I have same issue. Changed battery, usb-flex, no luck
Hi,
I have bought an used XZ.
The owner sold me this phone because he need new battery. I have replaced the old one after a week of test. The old battery works only for 6/10h and drain totally during night even if the phone is turned off. The new one have the same problem. I try to solve with an other battery, and nothing same problem. 12h of standby, after is totally drained. The strange thing is that I have the same battery life even when the phone is turned off, but not only this. If the phone is in 0% he charge without problem. If we have any % of battery I need to connect and disconnect the charger from a wall plug many and many times before he start charging. Phone give me the charge icon for a second and after nothing until I disconnect the charger from a wall plug(I have tested different charger and cable). During my investigation I have found that this phone results every time a little bit hot even if turned off. I have try to disconnect all is possibile, but the heat is from CPU! Now I know that this is the cause of fast discharging in all conditions.
Now I need to know if anyone with a "normal" unit feel the phone heat while turned off and while is on wich temperature have. Mine is every time on 34/35° in standby. Let me know,
thanks
i have same problem . sony xperia xz and sony corp is very very Rubbish
Hi Guys,
I found a way to charge my Xperia XZ with the same loop problem.
Try to push upper volume pad together with power button and plug in the charging cable.
Hold the buttons for 3-5 minutes - you will feel vibrating signals like 3 short and 1 long.
so hold it and then simply leave it for a several minutes and it should start to accept the charge.
Alex Kutikhin
Yes - I had this problem...fixed it by holding in POWER UP and OFF button for 120 seconds.
Do not let go...you will feel vibration (1 short, 3 short). Keep holding for 120 seconds.
Device should now be powered down. Plug in charger cable and leave device off until 100% charged.
Still no fix for the original post’s problem? Having the exact issue with my xzs right now.

Thanks for the hint...
Old Thread, I know, but I encountered this issue today on an Sony X compact - F5321. Fixed it and want to report back for the next guy.
Same symptoms, noticed first a slow charge, phone was drawing low current and only responding to cable after 10 seconds of plugging in. I than checked for data connection, couldn’t get any. Opened it changed the USB port - BINGO - that fixed the issue, everything working nice.
TLTR: no Solution in Software, it’s a faulty USB-port. change it.
Have a nice day.
