i rehoused me xperia play and when i tryed to turn it on i just got the blinking red light, so i bought a new battery that worked for 45 mins when it overheated to 47degress then died so i bought a external battery charger and the battery charges but when i put it in it overheats and dies in an hour and when it charges it gets even hotter and dies faster..... does anyone know how to fix this cause i cant afford to buy a new phone anytime soon
Are you using stock firmware or a custom one?
Stock
well the same thing happened to me..
i rehoused my mobile. but when i was closing up the phone, without putting in the back housing, i tried to switch on the phone so i would check if everything was fine or not. But what i did wrong here was that i just inserted the battery in wrong direction. Negative to the positive and vice versa. Nothing happened at that time, and the phone did not turn on. Upon realizing my mistake, i tried to power on my mobile again with the correct battery connections but this time the phone just wont turn on. There was a weird red light that started blinking and the phone just wont turn on.
so i completed the housing process thinking that maybe that was the problem and there was some sort of a sensor or something but that damn thing just wouldnt turn on. even if i put the mobile on charge it wouldnt turn on. so what i did was, i again opened up the back of my phone, deliberately put the battery in wrong position, tried to switch the phone on, and then i put the battery back again in the right direction and as i press the power button, walla, the phone is alive again.
BUT...
its getting HOT. damn HOT. after only being on for about 5 min, the battery got hot to 54C. upon inspection. i found out that the battery is not getting hot, but its the motherboard that is heating up.
i went to the service center, which opened up the board and found an IC that was damaged (caused by my battery mistake).
Found the IC from china. Ordered it, and TODAY it arrived. I will be going back to the service center, for replacement of the IC. If all is OK, i will let you know.
meanwhile, check out the pic of the IC that got damaged on my mobile during the process of rehousing and my stupidity.
hey thanks that helps cause i think i did the same thing with the battery...do u have a link to buy the new Ic?
FOUND a friend in china, and bought the IC from him ..
STATUS :
just now, after connecting the new IC, the phone has started working again. its NOT heating up. Everything is working fine..
EXCEPT
that now my phone shows no signals. In the settings when i search for other networks, i find many other networks also (MEANING THE TRANSMITTER IS WORKING FINE) but the phone just wont connect to my network and wont give me any signals.
I only get "EMERGENCY CALLS ONLY" status.
I am actually getting fed up of this set. Anyways, i hope u get the IC, and your phone works fine. ( I HOPE )

I did the exact same thing and have the same problem, but the difference is when i try the reverse method it still doesnt come on but cud i get a link to where u found the IC
The problem here is the same IC from the picture. Even though I found the replacement IC from China, I still couldn't get my set to start up normally without overheating. If you remove the IC from the board, the phone will start (even without the IC) but you will get no signals
For me, I was unable to get the phone back to its working condition. So I sold the phone as it was.

By inserting the battery in reversed position you probably caused some sort of short-circuit. You probably didn't burn only IC, but many different parts. When the part is damaged and short-circuit exist in it it heats up very very quickly as the current on this part (any many other parts that are connected with it) is very big (this also causes very quick battery drainage). So it means you had probably burnt the mainboard even if the phone switches on, so getting new mainboard is the only sollution to get the phone fully working (as I think you aren't proffessional who can diagnose and repair it. Neither do I ).
I hope this helped somehow.

Hello all I too have an xperia r800i play with the same problem or better the battery under the battery becomes very hot in a few minutes, and drain the battery quickly. Moreover, even when you plug in the charger not charging? only shows the loading icon but then not charged and only the LED flashing red?
And you can not start the phone FASTBOOT? because the LED flashes blue and then turns on a second phone in the normal
how can I do to fix?
thanks
Hey,
i have the same problem.
i tried isolating a pin from battery (the midle one) and i got it to work without heating, i thought it was fixed but then i took the battery back out and overheated again maybe theres something wrong with the pins any alternatives?
i did the same thing my phone is in the fridge now i boosted the battery by usb with bare wires got it started up hoping to get to 50% charge then try a reflash see if that works
So I woke up this morning to find my Tab drained. I plugged it in for half an hour, then when I picked it up I noticed there was no charging indicator (the green liquid battery thing). So I thought maybe I didn't plug it in right. I reattached everything, tested the charger on another device, then plugged it back into the tab for about 2 hours...still no juice. I tried powering on and doing the reset thing. still nothing. I brought it to a Samsung service center and they said I have a faulty motherboard. Now I'm wondering how the hell that happened when I've been using this device for about 6 months (only 6 months) without any issues, no overheating or strange reboots or anything, and now just like that I have a motherboard issue? The kicker here is that they're charging 75% of the tablet price to fix it! What gives?! I purchased it from a non-samsung mall store so they said I can't claim warranty. I popped the back off and did the battery pull thing and tried to charge - still nothing. Did I buy a device that decided it was a lemon after 6 months light-moderate use?
Anyone else have this happen? It's never been dropped or anything and I was on stock firmware with nothing but root.
In the UK, If your tablet goes faulty in 12months your guarantee is with the place you bought it from, not Samsung.
John.
It's ALIVE! I thought I'd get a 2nd opinion on my Tab since the guys at the Samsung service center popped it open anyway. Went to a generic phone repair store, all they did was hook it up to this box thing, and it came back to life! The guy said something got corrupted and just re flashed everything to stock rooted. He charged me less than $20 and I have a working Tab again. Obviously the very first thing I did with my resurrected device was to call Samsung's hotline and report how this one service center was trying to scam me into buying a motherboard that cost nearly as much as what I paid for the thing brand new.
Some li-poly battery have an protection circuit built in, if the voltage falls below a certain level say 2.5volts per cell, it disables the battery, if you connect an meter to the battery you will get 0volts , you need an li-ion charger that passes an higher voltage that resets the battery and allows it to work again, I wonder if this is what happened.

John.
Did they connect via USB or to the motherboard?
@tinderbox could be...must have over-drained itself for some reason.
@ashyx I couldn't really see what he was doing since his work table was obstructed by a bunch of stuff and he had his back towards me, I just saw him grab this small black box, then minutes later he showed me that the tab was already powering on though couldn't get past samsung logo, then he went ahead and flashed to stock.
Reason I ask is I wonder if he used a jtag box to ressurect it by reflashing the bootloader.
If he did there must be jtag points on the board as it can't usually be done via USB.
Pity you didn't ask what he actually did as I'm intrigued now.
Did the box look like this: riff box

Exactly the same or just similar?
yeah i think so... it had similar ports, though not sure about the outer shell of it... i think it was smooth all around with no ridges or anything, just a little black rectangular box.
Sorry to revive an old topic, but i thought i'd do an update instead of start a new one. Tab S died again and I'm now convinced it's over-discharge, as I left it at about 20% and forgot to plug it in before going to bed. Woke up with the tab drained, not responding to any button combinations, not charging with any of my chargers that tested ok with other devices.
Instead of bringing it back to the technician, I thought I'd try mcguyvering the damn thing. I opened up the back, pried the battery terminals up off the board, lifted the battery out, and with a spliced USB cord hooked up to a powerbank, I gave the battery terminals a direct zap, inserting the exposed USB wires into the battery terminals. This took some trial and error as, I didn't know which wire was supposed to go where, but finally I saw the powerbank leds blink, indicating it was discharging into something. I held the wires in place for about 5-10 minutes, noticing some heat on the battery by then. I reinstalled the battery back into the tablet, closed everything up and tried charging again and...hey presto! the tab started charging. :victory: Let it charge for 2 hours and powered on like nothing happened.
disclaimer:
I don't recommend you defibrillate your device's battery unless you know exactly what you're doing and are fully aware of the risks. (I didn't know what I was doing at the time but I was so frustrated at that point I didn't mind if the battery blew up in my face.)
Mine just dead last night while CHARGING (turned off at 13%).....
And refused to turn on till now (still charging and both warm (charger + tab)...
I even plugged an ampere meter to really know if its drawing any or not (it is, at 5.2V 1.7A for 15mins)...
And still no luck
Samsung's device become more ****ty each generations..... Esp the battery...
This one is the replacement batt they gave me after 2mos of usage for infamous Tab S battery issue...
I saw a video on youtube, a guy had a dead 10.5" T1 he took the back off and connected an 1amp microusb charger pcb to connections directly to the battery under a piece a tape, I bought a couple of the microusb charger pcb`s from ebay for 0.42p each in case mine goes dead.
EDIT: I found the video.

Samsung tablets only have issue with battery connectors. The white connector with 6 wires has loose connection, the black connector soldered to mainboard has cracked solder joints. New battery won't solve problem if you don't fix these two flaws. Resolder the battery connector will fix most of problems: not charging, reboot, flickering, auto shutdown.
I posted more details in the threat: flickering screen.
so the problem is Samdung's QC....
anyway no more somedung, I switched to Xiaomi Mi Mix, still preordering from China.....
You have to watch these chinies owened tablet and phone manufactues, they have been found to come with built in spyware, sending copys of all your texts ect back to china, it`s been in the news that last few day`s
Lenovo notebooks had a spyware app and Lenovo had to issue insturctions on hot to remove it once it was found.

That's OK, I can scan and remove all those spyware.
Still its better to have it properly supported with actual updates (older phone still got all UI + android update, hello MIUI 8).
Rather than using phone without proper software support....
Tab S - buggy and prolly the last MM update
Note 3 - useless LL update, very unstable, consider alpha
Note 8.0 - buggy last KK update, switched to CM13 and happy with it
I have a Zenfone 2 551, 2GB/16GB. Bought it 45 days ago. I bought an Asus Fast Charger later on. The first time I wanted to use the new fast charger the phone turned off.
I change to a regular charger and the led turned on (I had 40% battery at the time). Left the phone charging (standard original Asus Charger) and the battery instead of charging is loosing charge. Even with the led turned on.
Eventually the battery died. I tried other chargers. 1 out 10, maybe a got the led back on, but the battery stayed on 0% and wasn't enough to even turn on the phone
I've read several people having this same issue.

In one of the post someone wrote this tip
Thanks for the reply. But after a long day of stressing, it worked by itself. I read from an article about another android with quick charging that the USB could have not been all the way in in the adapter which, in my opinion, it was but regardless I repeatedly unplug and plug(15 mins -30 mins interval)... did the same with the phone plug and unplug till I saw the battery level going up
It didn't worked for me!
I've already tried:
a. Changing chargers and cables
b. Pressing power for 20 seconds
c. Pressing volume up + power
d. Plugging and unplugging the phone every 15 minutes
I bought the phone while visiting the US (I don't live there).
Has anyone else had this kind of problem, and was able to fix it?
Thanks
Can you confirm if the ASUS adapters/USB cables work with other USB devices? Have you tried charging from a PC? If so, unfortunately this issue sounds like a hardware related issue and will require sending on for warranty service. Please feel free to contact me direct at [email protected] if you have any questions or concerns.
Sincerely,

my phone died yesterday like that. i connect my phone to my computer with Asus usb cable the one comes with phone. my phone screen cracked about 1 month ago but it was not disturbing me so i didn't repaired it. right now nothing works on the phone.. at the moment i connect my phone it turned off and for 1 sec battery screen appaired then nothing. can't see my phone when i connect to pc with adb or something like that too so i think problem is more then screen but any idea ? @Asus_USA @Asus

The guy uses a metal tip pin to release the battery connector? seems that is risky and may short something out. These asus phones have so many issues, that's for sure.

So my zenfone 2 is rooted and today it ran out of battery. I put it on charger, there is no LED indicator lighting but ok, i thought it´s charging, so in few minutes i tried to power my device on, but i got only that low battery screen and it turn off after few seconds. I can get to this low battery screen even without charger, but it´s same. When i press power button in this low battery screen i get that bolt there, like it´s charging for a second but then it turn off. I also can´t get to recovery mode, even when i try it on that screen, it shows white battery with question mark. When i try it from turned off mobile, nothing happens. Please help me. Sorry for my bad english. Im sure that charger is OK because it works with other stuff and when i plug the mobile into pc, it´s just same, nothing. I have TWRP recovery btw.
Seems that you are having my same problem (http://forum.xda-developers.com/zenfone2/help/phone-wont-charge-tries-to-t3426130), but you can see the charging screen. Does your phone get hot while charging? Mine doesn't (so it is not charging) I bought the usb chargning module, hoping that it will arrive soon if that is the problem.

I had 7% battery and was on call, phone had shutdown suddenly and won't turn on or CHARGE.
When I press power button it just vibrates Twice. I had connected charger but it won't charge.
Besides it vibrates continuously every few (2-3) minutes (even without doing anything.).
I tried the following.
1). Charged overnight and tried on....Didnt work.
2). Opened the back panel and removed battery to mother board connection few times and connected back......it just vibrates . that's it
Pls help! Its out of warranty.

Let me know hoe it goes, because Im having the exact issue. I tried the steps from sukhwant717, but getting stopped at the step when it goes to the OS. Will keep my phone to charge for a few hours. I observe, that there is no heating up (battery), but will keep it for charging anyways.
Cheers

Thanks man....I did actually fix the phone...your awesome.....
It went something like this...
First phone refused to turn on....no charging light notification..it keeps vibrating.
Even @sukhwant717 method stopped at "os" thing.
After exhausting all option taken to a local service person who did something and told phones dead.
After coming home I have checked He RIPPED /SNAPPED ANTENNA cable.
I didn't bother much as phone was prononced dead!
After 30 to 40 days was casually reading @sukhwant717 thread and thought of trying again. I coonected charger and SUDDENLY I SAW ASUS BOOT SCREEN and phone was showing BATTERY WITH QUESTION MARK. I let it charge for sometime suddenly bootloader screen appeared but was not entering into recovery.(perhaps damaged bootloader , recovery).
Then I followed sukhwant717 method flashed bootloader and RAW image using ADB.
and phone RESURRECTED but with very low siganl.
It's due to RIPPED antenna cable.
And was getting good reception on 2nd SIM (perhaps uses different antenna/cable)
So I decided to order new Antenna Flex Cable but it's not available in India. So I went to ASUS SERVICE CENTER (near Brandfactory) in Hyderabad
and asked them the cost of Flex Cable, they said they won't sell spares...I have to RMA.
So I did and after two days I have received a call from them that "ITS FAULTY MOTHERBOARD" and will cost 11000 INR (USD 170, seriously ASUS),I said I rather want my phone in previous condition. I even told them to fix antenna cable ...I will manage.
They said their "TESTING SOFTWARE " failing device test even after connecting antenna cable.so they can't sell a part for a TEST FAILED device.
I told them it's because I had unlocked bootloader..the test is failing.they didn't have a clue abt bootloader unlcoking.
So again went to local market for the cable found A cable (though lil longer) and got it fixed for about 300INR ($5).
and got back the reception and typing with LTE connection on ZF2.
Thanks again @sukhwant717 ...
My observations: the issue could be due to
1) it's battery related issue (completely drained bir failed battery)
2) damaged bootloader
The people who have similar problem should leave the phone uncharged for 30 to 40 days even more and connect the charger and see if u see battery with ? Mark.
Or if new battery is available change battery and check....

The people who have similar problem should leave the phone uncharged for 30 to 40 days even more and connect the charger and see if u see battery with ? Mark.
Or if new battery is available change battery and check....

if you need antenna cable i can send you. but before that. send me pics of motherboard where antenna connector sits. don't ever believe local and service center guys. they are dumb enough to ruin things.

I had 7% battery and was on call, phone had shutdown suddenly and won't turn on or CHARGE.
When I press power button it just vibrates Twice. I had connected charger but it won't charge.
Besides it vibrates continuously every few (2-3) minutes (even without doing anything.).
I tried the following.
1). Charged overnight and tried on....Didnt work.
2). Opened the back panel and removed battery to mother board connection few times and connected back......it just vibrates . that's it
Pls help! Its out of warranty.

I had a similar problem, phone suddenly powered itself off and started vibrating. With the phone off and connecting the charger it started to charge, but after a while it started vibrating and overheating. I did a factory reset but the problem persisted. I flashed the raw firmware and it behaved properly for a while, but a few days ago the phone died. It does not turn on, does not charge, screen never turns on, no notification light, no vibration. But if connected to the charger it gets hot.
Left the mobile alone and tried to plug in after 35 days, IT WORKED. At first nothing happened but left it in charge for few hours. Later the mobile came back to life when I tried to turn it on..... 3 days in and still working just like it used to.... will have to take care not to let the battery drain below 20%
I am having same issue .. did you get it resolved ? Any luck ?
hello i'm having the same problem
will this method ensure that my data won't be lost?
