[Q] Q9 wireless charging problem

Hi!
I've just received the Q9 Wireless Charger from a manufacturer in china.
It's Qi-compatible and have been seen working with the Nexus 4.
Mine does not seem to work.
The manual says a led should be shining green when it's ready to charge or when it's charging. It's hard to read the chinese translated manual.
Mine just shines red and blue constantly and nothing is happening with the phone.
Am i doing something wrong? Do i have to activate it in my phone? I've tried putting it in any direction in any place on the pad.
Someone have a clue?
EDIT:

I have the Energizer Qi charger and when I place the phone on the charging plate, a light over the plate shines a steady blue until charging is complete. Flashing multiple colors (especially if one of them is red) probably means there is a problem with the charging system or the power.

That's what i'm afraid of. The thing is that the leads shows blue and red all the time, even when the phone's of the pad. Updating with a picture.

try position it with the centre?

Done that too...

Is the power cord connected securely? Maybe it's not pushed in completely (or shouldn't be pushed in so far).
For what it's worth that's not the Qi symbol on the charge plate.
If possible, send it back for replacement. It seems to me that those two LEDs should light up for no more hen a few seconds after the device is plugged in and then turn off until they nerd to indicate some condition like charge complete or error.

I have the Q9 charger for couple of days.
It's takes many tries of locating Nexus 4 on chargers surface to make it work.
Many times (most of my tries) I unable to make it work at all.
I am wary disappointed with this charger. It was waist of many.
I shouldn't have to be such cheapskate.

Q9 Qi-charger broken
I had mine for about a week now. Used it with my Nexus 4. Charges the Nexus quickly, but when at 100% it stops charging. Only when unplugging charger and re-plugging it, it will charge again. One morning Nexus was at 77% while laying on charger. After a few times unplugging, the connector was pushed into the charger leaving it useless. Do not buy!

Just got one too
I have to place my Nexus towards the top of the charger for it to activate and start charging.
Took me a while to find the correct placement.
My pad is supposed to flash blue when its charging - It starts charging and then seems to stop, then start again, then stop - not sure if this is normal or not.
So far i'm pretty disappointed with it, I assume because I got a cheapy from china that this isn't the normal experience with QI chargers, but I doubt I will be buying another until I see someone else with a much better model.

Nexus 7 Won't Turn On

Hey everyone,
I've tried searching, but no luck, so here's my issue.
My nexus 7 was around 25% battery last night so I plugged it in for the night.
Woke up this morning and the backlight was on, but the screen was off.
When I unplugged my n7 the backlight turned off. Hitting the power button had no effect.
I then tried pushing and holding the power button for roughly a minute, nothing.
I have disconnected the battery and still no response from the unit.
I plugged it back in for roughly a minute as well, still nothing.
Unfortunately I don't have access to a charger right now.
Is it possible the battery is dead even though it was on the charger all night?
Sent from my SAMSUNG-SGH-I747 using Tapatalk 2

Weird.
Just plugged it in to my car charger and it booted up. Battery is completely dead, so I guess with the backlight staying on all night it didn't charge.
Now why would the backlight stay on if the screen is off...

Don't go flashing different roms and kernels now like most of the idiots here, it could just have been your charger being faulty or a bad connection to the tablet overnight. if the problem happens again then you can investigate further.
BTW, were you charging from your PC/Laptop with a USB cable or through a wall adapter? i've had issues in the past charging my Nexus 4 and 7 not charging overnight on my PC

I feel like a broken record but since I've fixed a ton of n7s with loose battery connections, I would recommend checking the internal battery lead to make sure its not loose. Asus didn't do a good job of making sure all n7 batteries were secure and this allowed the battery to shift and pull the power lead out. Some clear scotch tape on the connector and one on the battery (avoid the copper tape areas) will eliminate this problem if that's what you have.

I ran into this problem. Initially, my Nexus 7 didn't start. When I plug in the charger the screen would flicker from time to time but there's no indication of charging. So I decided to open it up to see that the battery cable has loosened. So I managed to fix it and use it happily thinking that it won't happen again.
Since last week, the same issue happened. I thought it was the same issue and opened it up to see that the battery cable is firmly in place. So I got a shock. I removed it and re-inserted it again to see if it fixed it. But nope, it won't turn on. And now it's been a week and I don't know what to do It's nothing wrong with the loose cable cuz now it's firmly in place.
Now when I plug it in to charge, the screen will just flicker (as in the back light will turn on and off in 5 sec intervals). What do you think I should do? I tried holding the power button for 30 secs as well.
I bought this new from eBay and still under warranty. But I live in Sri Lanka. So when I bought it, I had to ship to a friend in the US and had to wait till he came down. So it's not easy for me to ship back and to receive another device. Hopefully I can find a solution to fix this myself.

Make sure that the cables between the battery and the connector are intact and not broken. One or two people reported a broken cable.
Does it boot while plugged in to the charger with the battery disconnected ? You could simply have a bad battery.

I checked again. The cables aren't broken. They are all in good shape.
It doesn't boot when I plug in. Actually it doesn't show anything on the screen. If I look closely I can see static flicker on the screen from time to time. Just like the static in TV but much much less. Like only a few of those in certain places.
When this happened the first time I opened it up to see the loose cable. So fixing that helped it then. But now I dunno what's causing it.

Might have to try a different charger, maybe something stronger. I JUST had that problem with my GF Nexus 7. It wouldn't boot with her normal charger and the screen would flicker like a TV. I used my Nexus 4 charger and it worked.
She had left the battery fully drain for over two weeks and I think the battery didn't appreciate it.

Completely bricked

Yesterday I updated my ROM using the goo.im manager. It seemed like everything was working fine, though this morning I tried to wake the tablet and it did nothing.
I can't get into recovery or the bootloader or anything. The screen is consistently black. I've tried holding down the power button, holding down the power button with volume buttons, pressing various buttons in rapid succession, but to no avail.
Any ideas for what I can do to fix this?
Thanks.

Could it have somehow discharged overnight? Plug it in and let it charge a little and see if it comes on?

It's been plugged in for a while now, and it's still not turning on.

In a dark room plug it in to the charger, see if the screen shows static, if so your battery may be unplugged.

Just tried this and didn't get anything. I don't think that's likely anyways, since I haven't opened up the tablet or messed around with the battery.

When you plugged the charger in did the screen show static? If so when you removed the cover did you make sure it was plugged in, or just look at it? The reason I ask is the plug will look plugged in, but the plug will not be fully seated.
And as nespid stated how long did you hold the buttons? It can take 30 seconds or so before it performs a hard reset or enters recovery.

I sometimes wonder about the craftsmanship of the power button. From day one, bone stock,I sometimes have to sit and fuss with the power button if its powered off.

I had exactly the same issue. Black screen, nothing from the power button. So I took the back off ( which comes off really easy.....just used my nails!) And pulled out the power to the battery reinserted, put the back on powered up and all was ok...........strange one....but it got mine up and running.

This, sometimes my N7 takes about 10 seconds to turn on, other times I'm pressing it for a minute or so.

More likely this is related to the sleep of death, where when you shut off your N7 it does not power down correctly and requires a hard reset by holding the power button down for 20-30 seconds.

This is what I would be trying at this point. And again, it can look like the plug is securely fastened when it's not if you have the battery that does not take up then entire space as shown in the pictures I posted.

Alright, so I opened up the cover and unplugged the battery and plugged it back in. Still not working :/

Odd, these are hard to brick. you would essentially have to start by wiping recovery/bootloader. It sounds like the battery is completely dead. what happens when you plug it in? I assume you see no indication of it charging? Again, in a dim/dark room can you see what looks like static when you plug it in?

Okay. So this happened to me a few months ago. It died from me not charging it for a few days ( love the battery life) so I plugged it in before I went to sleep. When I wore up and tried to turn it on, I was having the same issue. It would not boot or anything. It was dead as a doorknob and I thought. "No way....I bricked a device in my sleep....(next flashaholics anonymous meeting on Wednesday)"
So I thought maybe the charger broke and it didn't charge. Well I tried different chargers and outlets and everything. Nothing worked.
Then I plugged it into my computer to see if I could get the wugfresh toolkit to connect. (It didn't) but after like an hour messing with wugfresh while my nexus was plugged in I went to try to boot to fast boot (for the 100th time) and it worked (that or it showed the charging symbol by itself) either way the screen only remained on for a few seconds. After trying this again an hour later. Watching it closely, as soon as the screen turned on I ran it to my Asus charger and plugged it in.. Then it charged normally and was fine.
Tl;Dr
These batteries should never reach 0% mine probably became z little too close to 0% took a lot of time and methods to make the battery take the charge.
Moral: don't let the nexus 7 reach 0%

If it doesn't turn on and...
You reconnected your battery (dismounting the back),
You pushed the button for 5 minutes! or more (i tried all of em, all possible combinations)
You plugged/unplugged it from your PC then tried to turn it on
...and nothing happened.... Plug it to your PC, go to device manager and if it is recognized as APX
Welcome to the "BRICK CLUB"
Your only hope is to get in the bootloader

Yep mine did the same thing, my battery connecter was visibly wonky though, only slightly.
It does seem to me to be a small design problem that the battery can move a little and pull on the connecter, either the wire needs a bit more slack or the battery needs securing. I used some tape to hold it and hopefully this won't happen again.

(FIX) Red Blinking Light of Death

This may or may now help anyone.
I was using my phone and it just **** off on me. I wasn't flashing a rom or "tinkering" with it. I am rooted but was stock. No kernel. Connecting wall charger or connected to PC would just result in blinking red light.
I removed back cover (be careful doing this) and disconnected battery from mother board. Connected it back up and BAM...all is well. No loss of data...turned back on on the state I had left it.
Maybe this will help someone....

I'm 80% sure this has to be cuz of stock charger

did you try first just holding down the power button for like 10+ seconds? I get the red blink of death a lot in my car, I believe it is related somehow with thw wireless charging and it is shorting out or something with another component of my car. Anyway holding down the power button for a while reboots it.

And then the other 1000 that weren't charging or did use a different charger.
I don't believe it's the stock charger

I tried 5 different wall chargers (including stock charger). Three different USB cables on three different PC's. No change in results. Red blinking LED remained. I tried all combination of powering it on...Red blinking LED remained. I literally tired everything for 4hrs straight without any results.
Removing the back, disconnecting battery and reconnecting did the trick. It has been working perfectly for 6hrs now. Charges fine, no issues.

Very easy. Took about 3 minutes. I also had access to cell phone tools...basically a plastic separator tool (wont scratch or brake anything). You could also use a guitar pick or a plastic silverware knife.

I just received a Nexus and it is doing this exact thing.
I plug it in with my Samsung Tablet charger (2.0a so plenty of power) and get a SOLID red LED. After about 5 minutes, the Red LED turns off. If I try to power it on (power, vol down and power, all 3 buttons) with AC attached the Red LED just comes back on solid. Unplugged, nothing happens - no matter how long I hold down the buttons. Nothing is working!
Did I get stiffed with a crap device?

you gotta carefully take the back off and disconnected/reconnect the battery. that's your only hope.

Did anyone tried to not panic and just put the phone for a couple of hours into charger?
if the battery is completly discharged, connecting it to charger for 10 mins will not make the device run, trust me it works the same on Nexus 7.
Put the device to charger for at least half of day (6h) and then check if the problem still appear, if yes then RMA the device (openning it up may break the warranty).

This isn't the problem in a lot of the cases. I've had it happen to me now 10+ times. Sometimes the battery is almost full-charge. I can't RMA the device because I bought it at home (Wisconsin) and now I'm living in Germany.
For anybody wondering, you can buy a nexus from somebody else (as in the e-bay case) and transfer the warranty to your name.

This a "lot" of cases, are simply people who panicked and cant think straight (this is most common issue at Xda developers, especially when rooting phone ). The long charging test is the first thing you should check, if this will not help then its battery fault and need to be RMA'ead. But in most cases i'v readed , it was simply that battery was discharged fully, and phone needed time to charge it back to run device...
You still can RMA your device, it will just cost u more to send/recieve it from Google/LG.
And yes, if you bought a N4 purchased at google play and sold to you, the device ID must be transfered to new owner (old owner can simply send an email to google play). In case it will not be transfered and you will try to RMA te device, the original buyer will get it , not you.

Phone Dead (even more than a brick)

(fixed)I let my phone die because I wasn't near a charger. Now my phone is completely dead. I try to charge and nothing happens. It won't boot with lit black screen....nothing. It's like having the battery taken out.....
any known fix?
edit: (fixed) I waited and nothing happened so a bit after that I held the power button for 40 seconds then unplugged the charge and while still holding the power button plugged it back and the red/orange light came on. I then let it charge for a bit until the light turned off then I powered it on and worked. I experienced the problem once before but it did the red/orange light problem. It had never fully died like that before which freaked me out.

let it charge for atleast 30 minutes

nothing so far :/

i've had the same problem before.. the best method for make sure that n4 works again is simple, just dissasembly the back case and replace batery connector port and replace it back.
just follow Nexus 4 Teardown from iFixit.com
just remove the battery connector port. you don't need to remove all the battery.
