It's dead Jim.

OK, never had any auto resets, just had to manually restart often to cure various ills. Then yesterday it was stuck on the dimmest backlight setting. This morning picked it up from charging overnight and it's 100% dead. Switched batteries, plugged it into various computers and USB power sources. Dead.
Anyone brought a G2x back to life?

Have you tried a wall charger? If your battery discharges completely, like deader than dead, then sometimes you have to plug it into a wall charger and leave it there for several minutes before the phone will even show its connected to a charger.

I guess the real question to ask first is, what did you have it plugged in to? What kind of charger? Was it plugged into a surge protector?

It was plugged into the LG wall charger it came with overnight. I tried a iGo USB wall -> USB power supply and a USB port on my desktop windows PC.

It depends on how dead it is, if its a hardware defect of some sort then you're probably SOL. But, you don't have to be able to turn it on per se to use NVFlash, so if I were you I would try to see if you can get the device to be recognized using the APX drivers. If you can, then you might have a chance.

My G2x died after freaking up during one of the Davlik cache clears....
It originally would boot up and get stuck at "LG", but after a while it was completely unresponsive (not even a Boot Logo) and wouldn't even turn on. I thought it was fried. Luckily we have NVFlash that you can use without booting the phone up.
Take the battery out and press and hold the VOL keys, then plug it in. Your PC should "ping" letting you know something was connected. Then just reflash a recovery.
I did this a ton of times and it didn't work at first. I kept flashing stock then CWM, then stock, then CWM (different versions too). Eventually it displayed the LG logo and allowed me to boot into CWM where I flashed a new rom.
Been solid ever since.
I also read about this in the Asus Transformer forums (cause I just picked one up) and read about a guy experiencing the same thing.
Worth a shot. The NVFlash method will at least let you know if it is DEAD or just not working. If NVFlash doesn't connect then it is hosed. If NVFlash connects and accepts a new recovery, then something just got corrupted.

All good now! I unplugged, removed battery, let sit a while. Put the battery back in and it booted! Yet more strange behaviour from the G2x, but as usually I get it working again and stick with this phone.
But today I got a second from craigslist to play with alternate ROMs. Trying CM7.1 RC1 first, it's working pretty good on my Nook.

[Q] Shuts down completely when not charging

I posted this to another similar thread but they have solved their problem but mine is not solved.
A little background:
It was most recently upgraded to the the newest OTA and been stable since then. The unit is nearly 1 year old B50. So I know all about holding the power button down for different lengths for different purposes. It is NOT that. Until two days ago, everything was working fine.
First, I couldn't turn it on. I thought since I was travelling and using it a lot, it just ran the battery down. So when I got to the hotel room, I plugged it into the wall charger and it turned on. I was relieved for a while. Then I checked the battery (dual battery widget) and it shows 86%. When I was leaving the room, i pulled it off the wall and bam...it shuts down completely. Curious, I plugged in the charger and it boots back up (asus logo and whirling circle). I decided to leave it plugged in all night.
The next morning, I pulled it off the wall and bam, complete shut down. I plugged it back in and check the battery status. Still showing 86% and I notice it is not charging. I check the battery summary and it shows, battery = unknown error.
I did the hard reset (with it plugged in) VolDown/Power sequence. No luck. I decided to wait until i get home to test further.
At home, I plugged it into the dock. Widget shows the base battery is charging but the tablet is not charging. (it turns on when plugged into the base). It stays on even after I unplugged the base from the charger but the moment i remove the tablet from the base, it shuts of completely.
At that time, I decided to do a complete factory reset. After the reset, it is still having the same problem and dual battery widget is reporting the same unknown error problem.
In summary:
1) The unit will not turn on if I don't have the power cable plugged in.
2) When the cable is pulled out, the unit turns off and will not turn back on
3) When the cable is plugged in, it turns on and work just fine
4) When I put it on the keyboard dock, it turns on and work just fine
5) When I pull it out of the keyboard, it turns off and will not turn back on
6) I have soft reset, hard reset and factory reset (all with power plugged in) because nothing will happen without the power plugged in
7) Battery status shows 86% but not charging:
--When plugged into the wall
8) Battery status shows 86% but not charging while in the dock.
--The dock battery shows that it is charging and the light on the dock is green
I have tested and knows the charger works and the dock battery works.
The main unit battery will not deplete and will not charge and will not keep the unit running.
What do I need to do? Any thoughts? I would greatly appreciate some help.

Are you rooted? and did you try to clear the battery stats?
https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en
you can use that to clear your previous battery stats, and may help with getting a better reading on whats wrong. a messed up battery stat maybe messing with the charging process.

No, it is not rooted. I have just reset to factory settings again. But I might take that route soon if I don't hear from Asus. Is there an good detailed instructions for rooting my TF101?

you can start there. i got rooted when it was in HC didnt like the stock feel, so went to Prime Rom( honeycomb builds) the dev kept it close to stock but with some tweaks to the kernel. was a bit afraid to root at first, but just read through the tutorials, and just did it.
anyways Good luck!!

OK, nothing else seems to work. So, I am trying to go down this rooting road and using the battery calliberation tool.
As I was reading through the instructions, I find the build version supported is much older than mine (9.2.1.21) so, unless i am reading something wrong, this will not work.
Anyone has any other thoughts? Thanks in advance.

[Q] Sleep of Death - Phone does not wake up/power on

Hello,
I have a HTC myTouch 4G Slide that I have ordered used off of eBay. The phone was in excellent condition, the software seemed to be unmodified (factory ROM, Locked, S-ON).
It worked fine for a few days, but then it did not wake up, I had to remove the battery and then put it back to be able to power it up.
I have not really made a notice, but as I recall it must have been on USB charge for most of the time. Now I suppose this to be the reason why this issue did not came up earlier.
I started to suspect that it might be a power/battery issue, so I ordered a new battery (2450mAh Gold), but it did not help, the issue remained with the new battery.
I have also tried powering it off for the night, but most of the times I could not turn it on in the morning, even if it must have been at almost full charge.
Sometimes if I power it off (the nice way, from the OS) and try to power it on immediately, then it fails. Only a battery remove/replace will help to make it work again.
I have tried using it without a microsd card, and also without the SIM card. None of these helped.
It is still S-ON, but is now unlocked, plus I installed CwM Recovery (5.0.2.7).
The Bootloader is still 1.45.0013, but I have tried many different ROMs (scverhagen CM9.1+bat drain; SilverL AOKP and CM10; a few ones by WeekendsR2Short, and now it runs miui v4. 1.2). No help, the phone behaves the same.
I'm in Hungary, Europe, if it might make any effect (different frequency, whatever)
If it could be a hardware issue, do you have a hint on what it can be, or a suggestion on a tool to help monitor/track it down?
If it could be something that can be solved by using a special ROM, or special settings, I'd also appreciate.
Thanks. Solt

Hi,
I've bought the same phone as you yesterday, and I have similar issues.
I couldn't power it on. I supposed it came with a very-drained battery, so I plugged in. Pluggin it on the wall charger did nothing. Pluggin it on the usb connector produces the usb-sound on my pc, the charging led on the phone bliks twice, then it stays off.
I removed the battery, try other plug on my house, other usb cable... then, finally, conneting again to my usb get my phone with a solid orange led on. After a few hours (still orange) unplugged it and turned it on and it turned on! (40% battery level)
Buy my joy was short; the phone rebooted itself several times. I've used it (configuring, installing apps), then when it warned me about the battery going to 10%, I plug it on the wall charger. I left it over the table for a few hours, with the orange led. Then, I had to use it, and as I was about to pick it up, i've noticed the orange led was off. I picked it up and tried to turn on the screen... nothing happened.
Well, the same process again; tried different plugs, different usb cables, different usb ports... then, at last, again, blinking orange led, unplugged and replugged it several times until the led stays on.
I'll try my device a few days but i'm feeling very dissapointed, i think i will return it.
Regards,

Charging problem

Hello! I have my OnePlus One running one of the latest CM nightly build (20150827), and a few days ago I realised that there was a problem when I charge my phone. It seems to work well (the led puts red, the battery circle icon starts spining) but it's not charging at all. In fact when I left it alone for some hours, it has less battery than when I plugged it.
Today I reached 0% and when I plugged it the battery circle shows the lightning but it blinks between all red and all grey very fast, like if a was pluggin and unplugging it very fast. After several minutes it doesn't overtake 0%. If I disconnect it, it powers off inmediatly.
While I was writing this it suddenly got to 30%
I have tried several sources (official charger, Xiaomi power bank) and different usb cables. I've also experienced this with other nightly from a month ago (I flashed the newer to see if that works to solve it) and the problem only shows sometimes. Thank you for reading!

Sounds like a faulty usb port on the phone to me. If you're able to charge it at all you should try flashing the stock images to go back to stock, but only do this if you're able to get it to charge above 30% because of the phone powers off during the process it could brick the device.

I was just wishing it not to be a hardware problem... But if stock CM doesn't work I guess I'm opening a ticket. Let's see what happens

Battery completely dead or other hardware issue? [semi-resolved]

Hi All, my wifes s6 (using xtrestolite rom) has stopped taking a charge. Im trying to figure out what the issue is. Unfortunately im travelling for the next month so have limited trouble shooting options.
Background
- wife has been complaining that her phone battery dies quickly. I kind of dimissed her assuming it was in her head. she said it loses 10percent in standby mode in 1hr roughly. Shes been complaining about this for a week.
- yesterday at the airport her battery was at 12% and when we plugged it in to charge it wouldnt take a charge. Bolt icon did not come up and still said "connect charger" on the screen. Normally when connected the red Led comes on, but now it doesnt.
-our normal chsrging method is using and aukey 3port charger as fast charging mode.
Troubleshooting/diagnosis
- i have an s6 as well so i tested all the cables and chargers on my phone and it works. We even had the official samsung charger and cable but same issue.
- after the phone was completely dead, if you plug in the charging cable the charging bolt icon comes on for a few sec, the top left says "kernel is on seandroid enforcing" for a sec and then everything goes blank. Red charging led doesnt come on. So it seems like it detects the cable but wont charge enough to boot up.
- i was able to boot into twrp recovery but where its supposed to have a battery level its completely blank. Originally i was able to do this without any canles but then it wouldnt. My guess is that i orginally had a bit of juice and then it was completely dead.
-after leaving it plugged in for a sec, im able to turn it on where it boots and i can see it says 0% battery. It stays on for 5sec before turning off itself.
- i also tried plugging it into laptop, but laptop does not detect it. The phone does detect the power though and does the same as above but this time bolt charging icon stayes on for 1-2min before going off and seeing the "kernel is on seandroid icon". Once the seanadroid goes away nothing seems to happen. After doing this i was able to turn it on and it showed 1%. I thought this was promising but after trying this a few times ive never been able to get to 1percent again.
- with the brief charge thst i guess its getting, i was able to go i to twrp recovery and do a factory reset. This was with cable plugged in the whole time. Without cable in i dont think it would complete the action.
That about summarizes whats happened.
Ive concluded the following:
- charger and cables are ok and not the issue
- it is not the charging port since the phone does seem to be getting some juice bacause charging icon comes on for 2sec whenever cable is plugged in.
- its not a software/app issue since it wont charge even in recovery mode. Also factory reset was done and no luck.
My best guess is that the battery can only hold a 0-1% charge which is enough to register it being plugged in but not enough to do anything else. But if everything else is ok shouldnt it work when if the cable is just left in. This makes me think theres something else going on.
Any suggestions or theories would be much appreciated trying to decide if i should pay to get battery replaced.
Sorry for the long post. Figured it is best to give all info.
Thanks in advance!
Update June 3:
Hey everyone, just a correction on the above. It looks like it is able to charge in recovery (slowly). I realized that although there is no battery level during recovery, no charging led, and not booting up after being charged for a bit, maybe its just going slowly.
So i went into recovery and left it overnight on the non-fast charging and woke up after 8hrs and it was at 78percent!!!
Im not sure why it didnt go to 100% in 8hrs.
The phone still doesnt charge regularly when plugged in, so still need to fix that.
Do you guys think its a rom issue (only factory reset done before) ? I will see if i can get a rom for flashing.
Update 2:
Reflashed xtrestolite rom but still no luck. It wont charge.

Seems like a dead battery.

Battery.

Bump.
Went to the phone store and they said its probably not the battery but the ic chip for charging? This will cost 150, but doesnt include the screen if they break it...
Does this make sense since i can charge in recovery.
Thanks. Any direction or input is much appreciated.

Go on the local store and change your battery (if isn't in warranty)

Hi all, just wanted to update the post that the issue is semi-fixed.
I brought it into a repair shop who offered to diagnose the problem for free before paying to replace the battery.
He told me there was nothing wrong with it and not sure what my issue was. Plugs in the charger and lo and behold it was charging. He said he didnt do anytning to it except blow some compressed air on the port.
Im guessing the comporessed air cleaned out a short? So now it charges properly.
The issue remaining is that the pc doesnt detect the phone. It shows as charging on the phone but no conmection. Tried to install the latest samung driver (1.5.4xxx?) but no luck. On occation sometimes it says "usb port has malfunctioned" but other times nothing.
My s6 does actually connect, so definitely my wife's s6 itself and not comp. Im tempted to buy some comlressed air and give it ankther blow, but dont want to risk messing it up again. im pretty happy that it at least charges up.
Hope this helps others that might have similar issue.
