My Xoom learned a new trick...

...Play dead.
We all know how brilliant a design the charge cord adapter is, I myself am on to my third one in almost two years. Well, the tablet stopped charging today and no matter which wall outlet I used or how much I wiggled the lead I could not make the light come on. Seeing that my Verizon contract is all but done at the end of this month and rather than buy another charge cord I decided to buy a new tab. I just picked up the new Asus Transformer Infinity, not too bad so far. Anyways, about 20 minutes after getting home with neither tablet charged to a useable level, the power goes out for a couple hours- just my luck too. When the power came back on suddenly the light on the Xoom came on. I hadn't touched it since I gave up on trying to get it to charge. Now here I am with two tablets and a $500 hole in my pocket. I know I was bound to get a new one eventually so I'm going to hang on to it but I never saw it happening like this.
Has anyone else had any issues regarding their chargers? Or anything unusual occur in general? I'm sure I'm not alone.

Ouch I would hate to folk out another $500 dollars for a new tablet even though my old one still works. I don't use my tablet for any intensive apps like games, so a new one would be pretty pointless for me. I never had any issues with my charger, well one time one of my charger did blow up, but that's because the battery was faulty for my jump charger for my car. Other than that, you might have some dust in the charger pin hole? Just a guess really.

I'm on my third charger since March. Original Motorola one died, second one (off eBay) burnt out, current one (off eBay) still working but I can't use the touchscreen while unit is charging.
I live remote using an off-grid power supply so this may have something to do with it.

Huh. I have four of them, from the original back in Feb '11 to one I was given a few months back, and they all work perfectly- and most of 'em are used every week (two at home, one in the office, one for travel).

agreed with kcrudup, ive been through 2, the only reason being i snapped the connector on the first one when i pulled it out at a bad angle

The charger that came with my refurbished Xoom lasted almost through the first charge. I thought I was going to have to send the whole thing back until I took it into the Verizon store and verified that it charged with a different charger. I've since got one off eBay and another with the standard dock. Both have been holding out so far.
Oh and my Xoom touch screen doesn't respond while charging either. Somewhere I read that a factory reset will fix that... but I'm waiting until my 90 day warantee is up to put EOS on it since my BT mouse works while it is charging.

My original charger is still working and I got my tablet 8 months back. I think the charger has lasted pretty well. How long did peoples original ones seem to last?

That's an electrical problem (noise and/or grounding issues with the charger raise the "noise floor" so the touchscreen controller has trouble determining what's a valid touch) and can't be cured by any reset, factory or full or ...
Your issue is your charger- try another.

Just a quick note.. I've had the ebay sourced chargers fail on my xoom ( and other devices). I found that the power ratings on some of them are rather optimistic... they simply are running at the outer limits to charge the tablet and failure can be internal to the power unit...best case.. or worst case failure dumps overvoltage or raw AC power to the tablet.
Fortunately my failed units were of the internal power supply version.. and aside from bad smells no real damage was done.
I have successfully built charger/power units after scavenging the connector from my failed power supplies and using a minimum 1.5 amp 12v dc supply... they seem to work fine.. and keeping one handy is much more convenient than wondering where I last used it :fingers-crossed:
as always.. your mileage may vary

Hmm, that's interesting. Unfortunately this charger is from Verizon and i would surely hope that their stuff work to the correct specs. I wonder sometimes that maybe the problem could be with the contact inside the tablet. Could that have something to so with it?

I think the Motorola/Verizon chargrs are good. I think the earthing issue is with the cheap chargers from China.

When I lost my cellphone charger I had to buy a Chinese one, well, when charging it looked like possessed by the Devil itself lol! The screen started acting strange and I wasn't able to control it... Then I found my original charger and the exorcism was complete lol^2! BTW, a guy on X10 mini pro community (one of the best developers I ever met - my favorite one ) lost a cellphone with a Chinese charger, so what can I say - be careful with it!

[Q] Motherboard replacement

Yesterday I picked up a used Nexus 7 with a bootloop issue.. spent $10 so I figured worst case I bought an expensive charger for my phone. Either way, it looks like the bootloader is locked and I can't unlock it. Everything I've read seems to point to a bad emmc chip. Would replacing the motherboard solve this issue (assuming the new motherboard doesn't have the same defect). Also could I replace this one (an 8gb) with a 16 or 32 gb board?

I changed my motherboard from 16 to 32gb. All went without a hitch. I got this one...

Did you just want to upgrade or was there an issue with the original 16GB? If it's good (and you still have it) would you want to sell it?

I assume my motherboard is zapped. I can charge my Grouper while it's unplugged but no device will recognize it. I made the mistake of upgrading my partition with this issue, now I have a fancy paperweight. Thoughts?

I just ordered an 8GB replacement motherboard from eBay, cost $16.99. I'm figuring I'll be into this thing for a bit under $30 if all works out so worth the gamble I guess. I'll update once it comes in.

My new 32 gb motherboard arrived, and I installed it right away- I felt like it was Christmas morning. Fast forward to closing the case, and I get no power. Not even a weak attempt. I went through everything, it's all properly attached. Still nothing. It's currently charging with no LED light on. I am not optimistic. Anyone have any suggestions?

I replaced my boards also.... Bought a used unit that came from a Nexus that someone had broken the screen on.... So, I received the frame with camera/speaker and boards attached.... only thing missing was the usb/headphone piece which I just took from my old frame....
Put everything together.... sealed it up..... plugged it in..... Nothing...... mild heart attack..... But then, I let it charge for 10 minutes... returned to the unit and pressed and held the power button.... and it fired up....
So, as I don't have a suggestion on if there is something internally wrong.... But sure, that the battery is plugged in securely and give that power button another shot after charging for a little while...

Motherboard came in yesterday, couldn't have been easier to install just have to watch the plastic clips on the ribbon cable connectors, I broke one on the old motherboard, if they are anything like the PS3 if they break you're SOL. The new MB was on 4.2 so I went through the upgrade procedure to 5.0.2 and wow it runs lollipop nicely. Also I ended up getting a 16gb MB so that worked out well.
Try and use a regular tablet charger, which I think is 1.3 or 2.3 amps and not one of the generic chargers which are lower - you will notice a huge difference in charging time. I'm using the tablet charger on my S4 and it goes from 10% to 100% in around an hour.

New Battery problem :/

Hello
So i bought a new battery and replaced the old one.
I then had the flashing red led, i got it to download mode, plugged it into my pc and then the red flashing stopped and now it looks like its hardbricked :/ does anyone have a solution or have an exprience like it?
It is a nexus 4 rooted with cm 12.1 and twrp (can't remember which)

The flashing red LED probably means that the battery is completely drained.
Plug it into a 2.0 amp charger for a few hours and see what happens.

If you give it enough time to charge, and it is an aftermarket battery, especially from Ebay, there are a ton of garbage worthless batteries out there. I picked an Ebay battery, but one with good reviews here on XDA.

Can you give us a link? I was thinking about replacing my battery as well.
I did the charger port/mic/LED replacement last week and it was super-easy, so I may as well give the battery a try as well.

First thing, if you can get the real LG battery, just get it from LG. Unfortunately in the US, you have to send the phone in for repair.
So, here is the thread I went by:
http://forum.xda-developers.com/nexus-4/accessories/to-buy-original-battery-t3110029
From that thread I bought this battery and it works OK:

charging port board replacement

Hi, has anyone replaced their usb c charging port board?
I've searched some on Amazon but they are not OEM. I am wondering if the replacement will fast charge or not?
Right now my port is kinda loose and I have to position the cable a certain way for it to charge. And the slightest and smallest touch will knock the cable out. And it doesn't fast charge.

Yes, a few people have changed the daughterboard with complete success, however I remember one guy reported fast charging not working afterwards. Bottom line seems to be "beware" and shop carefully.... just like with batteries there are some faulty replacement parts out there. At this point it sounds like you don't really have a choice in the matter. No sense taking a chance damaging your phone (further) with a loose charging port.

I bought mine used, so within a month I bought myself a new charging daughter card and a replacement battery. I ended up buying two. The first didn't work for me, the second replacement I did a couple weeks later with the new battery. This time it worked better. I recommend you try to find an oem part or as close to it. For me the first part was slightly different than the original piece, but the second one I ordered looked identical to the original I took out. If you have not opened up the device yet, then watch some videos of tear downs and watch closely for the daughter card so you can compare against which one you order.

Device temperature too low, can't charge oneplus 5

I own an OnePlus 5 that I have used for a couple of months with stock OOS and locked bootloader and unrooted. I have always used an original dash charger and cable. However, few days ago the phone became unresponsive to the charger and after the battery died. When I reconnect the charger now, it gives a message that device temperature too low, can not charge and when I turn it on the battery shows 50% charge when I remove the charger it turns off after a short while. The phone didn't suffer any drop or water damage or any other kind of accident. The phone is not under warranty so, I need to find a way to charge the phone. I have searched for the problem on many forums and some point out to a faulty temperature sensor on the battery and others point to the daughter charging board while some say there's an issue with the motherboard. Is there anyone who could troubleshoot the problem precisely.
Or, Is there a way, to flash a custom kernel which could turn off the temperature sensor on the battery, if it's there.
Also, needed to know that will the problem go away after a battery replacement?
I have wiped cache and data, downgraded the phone from Pie to Oreo and nothing seemed to work. Some people suggested putting it to rest for 24 hours, I also did that, but to no avail.

seems like the thermistor in the battery died ,i suggest to swap the battery with a new one

Are you sure that the temperature sensor is located on the battery or inside the battery? Because, if I buy a new battery that would mean I can not get it replaced if the issue is not with the battery.
I have to order it online as the battery is not available in the local market.

Sorry for being overly cautious about the issue. I have searched some forums where people couldn't get the issue resolved even after changing the battery.
Still, I am thankful regarding your input and replies.
But is there, a custom kernel available where the battery sensor could be bypassed for the cell to charge?

Before buying anything or opening the phone yourself contact OnePlus. If the phone is under warranty probably they will take care of it. (even if, many times, the battery doesn't have the same warranty as the rest of the phone)

i haven't faced this issue on the op5 ,but in the past i have faced it in other phones (not charging with battery is too cold message)either way a replacement is pretty cheap i would go for it ..(i don't think it's a good idea trying to dissable it ,the same sensor is responsible for the current that the battery is receiving so i don't think you can dissable it at all because the phone will not know at what amps to charge the battery,i bet it won't charge or extremely it will become galaxy note 7 bomb :silly: )

Dear the problem is that the phone is not covered under any warranty. I purchased it locally from a shop that doesn't provide warranty for any phone. I live in Pakistan, I tried contacting OnePlus but seems like they don't have any official stores in Pakistan. I guess, there's a service centre with whom they have partnership for services.
I guess, I have to contact them.

Hi, just curious about the update on this one? I've also encountered the same issue on my OP5 and still waiting for the battery replacement I ordered hoping that it is a faulty battery.

I didn't have the low temperature issue but my charging port did start to fail so I replaced it and the battery last month. The hardest part is getting the back off. The screen snaps in much tighter than most phones I've worked on which were glued shut.
I got my parts from E-Trade supply but I never will again. The charging port I got for an iPhone 6 I'm repairing was defective and they would only credit the part and not the $22 in shipping I paid them. They eventually did, but only because I bought several items over the past few years and I started putting up bad reviews on them. Never again.
The parts for the OnePlus 5 were okay although the brand new battery is only at 91% health. The original 16 month old one was 83% still a gain.

Hey brother, did the battery replacement fix the issue?? I have been having the same problem since today morning.

[Update] Was able to bring my OP5 to a local tech who is trusted to fix OnePlus devices but unfortunately the problem on my phone is with the motherboard. Tech already tried replacing the battery as well as the charging port to no avail, so I may have to stick with my OnePlus 5 permanently connected to a power source while I wait for the upgrade(OnePlus 7) to be released.

The same thing with me, I trying now to fix this, but... I can,t

Mobo issue
After almost a month with the local tech, he was able to order a spare part for the issue with my OP5 motherboard. Fingers crossed hoping that it will be fixed within this week, it already cost me $100 :crying: I'll update on which part needs to be replaced if the issue is with the motherboard itself.

[UPDATE] A Battery replacement by OnePlus solved my problem. It also fixed certain other issues I was having like 3hr SOT, random shutdowns before reaching 0% etc. Cost me ₹1600 (around $22.5)

Good luck. I hope your issue gets fixed soon

Man I paid about the same for the battery and replaced it myself. But at least I didn't have to send it away. Unfortunately my only other phone (HTC one M8) doesn't work on my carrier.

[Update] My OP5's alive and kicking again. It cost me $40 for the board to be fixed, $60 for the front glass replacement.

Here's the pic of what was replaced on the motherboard

Sad to hear this is still going on with OnePlus phones. I had this problem with my 3T. Replaced everything, except the motherboard. I'm figuring it's that, but at this point I don't care. A replacement is anywhere from $80 to $150. You could buy a new 3T outright for that price.
