[Q] 7.7 Initial Charge Concern/Question

Hi all, I've seen that some of you seem fairly knowledgeable about the initial charge process of the 7.7 and I have a quick worry.
When I received my new Tab, I pulled it out of the box and plugged it into my computer to charge. (I had not yet had a chance to go out and get an American adapter as my WiFi only version was the Euro Model). The battery icon came up for a few minutes and showed as charging but then disappeared.
Concerned that it would not come back on, I went ahead and hit the power button. What happens now is that I will see a brief flash of the Samsung logo then the screen will go dark, and I will here the boot up chimes as well as feel a little capacitive buzz. I've been able (I think) to turn it back off but I still get no charging image (I've since gone out and picked up a newer travel charger). Is this standard during the first charge? I'm hoping I didn't manage to get myself a defective unit...
Thank you in advance!

I didn't charge mine before turning it on; they usually ship with the battery around half charged or a little less. In theory, they don't charge over USB--though this isn't entirely true as I have had my tab's battery charge a very little bit after being plugged into my computer for a while. I haven't tried that while the tab was off though so I don't know what to expect in that case.
I don't quite understand from what you wrote whether it actually booted properly though. It should boot just fine--glowing samsung logo, boot animation, welcome to android screen. If it didn't work, I'd try booting while unplugged from the computer. If you manage to charge from an A/C adapter and it still won't boot, try getting into recovery or download mode (hold vol up or down, respectively, while holding power to turn it on). If you can't get to boot into anything with it plugged into A/C, you're screwed.

Yeah, I have a feeling you may be right, on the 'Screwed' bit. . That's what I get for buying an import I suppose.

How long has it been since you plugged it in to the wall charger? Give it an hour or so...

It's been a few, that's why I was concerned.

Quick update, I saw the briefest flash of a 100% on a blue charge bar. So I'm going to have to assume I have a bad unit. Thank you all for the advice and suggestion!

That sucks. Where did you buy from? Negri or expansys should replace it, though I have no idea about ebay sellers. :/ Good luck!

It was a Negri buy- so hopefully they'll be cool about it. 48 hours though before I'll know for sure.

Heh. I think Negri crawls XDA searching for mentions so they probably already know about it. Hope you get it fixed.

Sleep of Death hard brick

I've been running Revolver 4 beta for a few weeks, and experiencing the random reboot/sleep of death that ICS seems to bring. It's obnoxious, but I can live with it.
Today, though, I got home from work, and the thing will not boot at all. I mean, nothing. No Asus logo, no recovery, no screen on at all.
I have a replacement plan from Best Buy, so I'm probably just going to get it replaced tomorrow, but I'm curious if I'm the only one to have this issue.
Also, I imagine that short of replacing it, I'm boned, right?
Edit: I'm a complete moron. My charger is plugged in behind the couch, and apparently came unplugged sometime over the past few days. I apologize. Please laugh at me, and delete this thread, if possible.

Try connecting to the usb port on PC and let it sit 8-10 hrs off. It may have woken up and run down the battery. If the bat is too low the standard charger will not charge it. Getting the bat level up a little may let it charge again.

dropped my nexus now it only charges while off

well as I'm sure you all did.... the first thing I did when you got your N7 was to unlock and root it so you could load up all the games that you worked hard at on your phone... everything was great until it slipped off of my car seat when I got home and now it will not recognise the USB port while its powered on... my computer will not recognize the device at all to transfer data either... luckily I have already unlocked/ rooted and loaded team win recovery...
so here is my question... where can I look to see if something got broken when I dropped it... I took off the back cover and and everything looks ok...
my other question is will google replace it if I send it back saying that the cable does not charge while powered on... I can not relock/ return to stock without usb/adb connection
the length of turn around time that I hear about with the 16gb models I might wait it out to see if I can deal with it... I have a wifi web sharing app that I can use even though its very slow compared to a direct cable

If you can get back to the stock rom ...I'd sent it back if it's all possible.The Rma is quick and painless if your tablet was bought on Google Play.
- The turn around time for me on a 8gb and 16 gb tablets from Google play was just a few days. (Under a week from the time I called until the time I got my tablets in my hands. )

Well I let it charge off for the night and it is charged 100%... I guess I'll just rely on wifi connectivity for a while and see if I can manage before I try and return it

That really sucks man typically they won't replace a device that has been unlocked. Have you tried a factory reset yet? I I know it sounds unlikely but I have had accelerometers go to "sleep" from being dropped and or a faulty rom and a factory reset brought it back. Its really weird since you do get a charge when its off.. if it was broken hardware I would think you wouldn't get a charge at all. Make sure you do a nandroid backup before so you can get your apps back if it doesn't fix your problem.
Also about the RMA for the 16gb I believe now they are actually out of that model at the time. They may have a stash just for returns but if you decide to try a return I would make sure to find out what the estimated wait time would be.

Yea that's the weird part... But I did flash it back to stock ROM but nothing worked... If I could get USB to work I could flash it back to stock and lock it... Its a loose wire somewhere inside I'm thinking

My N7 16gb charged properly on the first charge. Now on the second charge, it will only charge while powered off. My device is stock and has not been dropped.
I plugged it in last night, while powered on, and woke up to find the battery in about the same state that it was in 8 hours earlier. That was with it plugged into a 2.5 amp HP Touchpad charger. I tried plugging it into a 1 amp charger and got no indication that it e was charging, until i turned it off. Then it put up the charging indicator. I will try using the N7 charger and see if that makes any difference.
It is possible, but very unlikely, that the device is doing a handshake with the charger when the device is powered on, and if it fails then refuses to charge. If that were happening i would expect to see a warning pop up on the device.
UPDATE: My device will charge properly off the asus charger that came with it. It totally sucks that the N7 appears to do a handshake with the charger. My advice to the OP is to make sure you only use the original charger.

Does ADB wireless work? Might not help you with fastboot, but you could push/pull files...

Yes all wireless connections work fine... But I guess I'm just going to have to live with this issue since it was my fault but at least I am already rooted with custom recovery so I might get lucky and have a kernel that might be able to fix it...

Based on the post about the charger "handshake," maybe it's the charger that's gone bad, and not the device?

I dropped it cracked screen and can't unlock the screen, UK Repairs
Hi, hope someone can help :-0
I dropped my Nexus (oh dear!) and the screen's cracked. It powers OK, just I can't unlock as the touchscreen is not responding.
Asus UK can repair it, but can't quote me a price (because they've had so few repairs in yet)
Questions:
1. Anyone dealt with Asus UK repairs? Or any ideas of the costs of replacing a broken screen?
2. Can I reset the device by just using the on/off and volume keys as the touchscreen is dead
Thanks

As long as you have adb connection you can reset it to stock... I've got no USB connection so I cant... wugfresh toolkit has all the proper files to flash the stock image...
I've been doing OK with no USB... I charge it at night and I last me all day easily

(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.

How hard is it to remove the back panel and remove the battery?

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?

What really sucks...if you call and exchange it with them. They will want to hold the purchase amount on your card til they get the old one back.

Unfortunately I purchased this from ebay - just my luck it comes back in the play store the week I finally get one at a decent price! I'm going to leave it charging overnight, but I don't have high hopes. I'm really bummed out.

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

I noticed my Belkin car charger started wheezing and the phone displayed the charging icon on and off. But disconnected before anything happened..

I have nothing with which to separate the back and that would invalidate any hope I have of receiving a refund from the seller.

If you have paid with paypal check if you have buyers protection.
Then first contact the seller and if he ignores you then contact paypal about the issue.

If you take your time there is no way anyone can tell you've taken the back off.

I'll have a try.

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.

Think my phone is dead. Won't boot. any ideas?

I've been having a few issues with my Nexus 4 on 5.1.1.
Twice in the past month I've had random Force closures of all aps. Facebook was the worst. But then it goes on to all other apps including the launcher.
First time that happened I did a factory reset and things went well. Yesterday it happened again while it was on another charger and I can get my phone to boot.
The screen backlight looks like is on when it's plugged into the charger and will go out if I hold the power button down for 5 to 10 seconds.
If I hold the power button down for 10 seconds when the charger is connected the LED flashes red till I take my finger of the Power button.
I've let it charge overnight (12 hours) and I've tried holding both volume buttons with the power button.
As well as Volume up and Volume down separately with the power button.
Is the phone dead? anyone got any ideas on how to bring it back to life
I've got a screwdriver set on order as I don't have fine enough star screwdriver to remove the internal battery connection. Which is my next step..

I think you are right to try replacing your old battery. Be careful while scraping it out where it is glued in not to tear it up too bad because it can 'splode. Might want to use a plastic card for that. I used a metal shim, an iOpener, and am much better now...

I'm going to try just unplugging the battery from the board first before I attempt to replace it.
Think it's time for an upgrade anyway.
Got my eye on the "OnePlus-X" as my next phone.

Removed the battery and stuck my multimeter into it.
It's got V output of 3.61 volts but amps drop off a cliff to zero as soon as I touch the contacts.
New battery arriving tomorrow.

i have the same problem with my nexus 4 dude. it boots when it is connected to the charger. basically it works like a desktop. I went into recovery mode and did a fectory data reset and wiped all the cache. Pliz help me proceeed. I kind have a hunch that its a software thing. did yours start working ater change of battery? Thanks ..

yes dude. i can go to recovery without it even being plugged in. I m pretty frustrated. I plan on giving it to the repair centre but he will charge me a bit high. Doesnt matter will let you guys know if I do find a solution.

Well my "new" battery arrived yesterday.
And it's getting sent back today!!
Got it through Amazon and when the battery arrived it looked ok but would not charge. I took it out to check the contacts and the ribbon came away form the battery! Looks like it was not soldered to the battery properly (if it ever was!) Just glad it didn't cause a short and kill the phone or myself.
Getting one from a different supplier tomorrow. Hopefully this one will work!

Please let me know! I've ordered a third battery just now. The first one was an aftermarket one, the second one was apparently a knock-off, this one was smaller than the original one.
The third one is hopefully a genuine LG one since the reseller is listed on LG their site.

Dam!!
Replacement battery arrived today. Looks good.
Installed it and the same thing is happening!
Screen backlight goes on. does not seem to be charging!
Now thinking the motherboard is buggered!
But I'll keep the phone on charge overnight just in case...

Damn that sucks to hear man. Hope it works tomorrow!

Now just searching freebe sites and eBay for any damaged cracked nexus4's I could scavenge from
