Hello! let's just cut to the chase. I need help..
Couple of days ago I got tired of waiting for the new ota for my phone so I decided to root.. unlocking bootloader went well, installed newest cwm, made a backup of my rom and chose renovate 3.0 as my first rom to try... everything works normal and I update the faux kernel on the rom to version 5b01.. all works normally at this point.. I play games, listen to music, surf the web.. yesterday I then updated the kernel to 5b03.. I went playing dark knigt rises (btw a very good game) and the phone heats up pretty much (which I think is normal as the game is quite heavy and I use wilkyys game booster app). I play about 15minutes and I get the message that the battery is running low, I plug the charger in and continue.. five minutes go and the phone freezes and the screen goes black.. the phone is connected to the charger and the charging light blinks red.. the phone won't start, even when pressing the power key for 10seconds. I can get to the bootloader and recovery _when_ the phone is connected to the charger thou.. if I unplug the charger the phone won't do anything. I search the problem on xda and find some threads about similar problems.. eventually after changing from the wallcharger to the usb charger on my pc (did this many times..) the red light goes solid and I press power and the phone boots normally.. weehee I made it!! or so I thought..
Next day: I woke up and the phone was in charger all night. Battery reads 100%. I load "system tuner" and experiment with undervolting my phone (only -50mv) and run some benchmarks and everything seems working.. I start to download an app from the play store.. the phone freezes and again the same flashing red light is to be seen, I thought it could be because of the undervolt but I'm not sure anymore.. and now I haven't got the phone in working condition.. I have now got the phone in recovery for about three hours and there should be enough juice for it to start but it wont..
I also restored my backup but that didin't help.. with the getvar battery-voltage command it reads about 2500mv which should be enough to atleast power it on?

2500mv is far too low for lithium ion batteries. There are protection mechanisms in most lithium ion batteries that will trigger at 2.7volts or lower putting the battery and its protection circuitry into deep sleep.
From the battery university: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries/
Li-ion should never be discharged too low, and there are several safeguards to prevent this from happening. The equipment cuts off when the battery discharges to about 3.0V/cell, stopping the current flow. If the discharge continues to about 2.70V/cell or lower, the battery’s protection circuit puts the battery into a sleep mode. This renders the pack unserviceable and a recharge with most chargers is not possible. To prevent a battery from falling asleep, apply a partial charge before a long storage period.
If this is the case you may not be able to recover easily. We can only assume something went wrong with the phones firmware that caused it to deeply discharge and now protection measures have kicked in.

hmm.. thanks for the answer.. last night I got the charging light to stay solid when I plugged the phone in and I was so happy.. but I was so stupid and tried immediatly to turn it on.. it even started and got to the quietly brilliant screen, but died pretty soon and the red light started blinking again.. then I realised I should have kept it charging for a while before trying to turn it on... god damn it..

When lithium batteries are deep discharge (below 2.7volt) changes take place which can cause short circuits in the battery, recharging then becomes dangerous, hence the battery goes into a form of safety mode, it's like a fuse blowing. It may never take a charge again, or if it does, the battery life will be less than before.
Hope it recovers okay however if it really did hit 2.5volt it could be permanently damaged now.

mine was doing that for a while. Keep it plugged in, if the wall charger doesnt work hook it up to a computer. it will turn on again...
simple keep the phone on charge for few hours and dont touch it.
Ok back to the problem.. the phone was in charger yesterday for about 12hours.. and still won't show any signs of recovery.. blinking red light continues... I might just have to accept that I have to send it in to repair... sigh.. and I think I have to pay for it..
As I said in my first post I have restored a nandroid backup of which I made as soon as I installed cwm.. so I should be at stock firmware? allthou I can't confirm it as I can't get the phone to boot but cwm said restore was succesful.. next step is to install original recovery and relock the phone, am I correct? so next question is.. is there anyway to do this as everytime I try to flash something with flasboot I end up with "failed: low battery"...?

I've experienced this kind of problem when I drain the battery flat; naturally, I crapped myself like everyone else since there's no easy way to remove the battery like you would for any other phone.
All I did (and still do) when this happens is hold the power button until the main buttons flash white a few times, let go and it should reboot the phone..
two minutes pressing power button, nothing happens

did the buttons even flash??
Try holding vol down + power until you get a response, then try holding the power button again ..
for me the key was to get the buttons to flash white, thats when i knew things were gonna be ok! :highfive:

no response! only response is that when it's in charger I can get to to blootlader and recovery with the vol- power combination..

Tried that :/ won't work.. as my phone doesnt restart with the script.. only way to get a response from it is to press power and vol down when in charger...
Thanks for the suggestion thou.
all right.. quick update.. I have sent the phone in for repair.. so just waiting for the repair bill
Ok... update (don't know if anyones interested..) Today I got at txt message from my carrier that the phone is now ready.. and what do you know.. it was covered by warranty. They changed the motherboard and the screen module (I had one dead pixel) needless to say Im pretty happy now.

Don't you just love it when that happens.
I had a rooted phone and my warranty was probably void. A week ago I dropped the phone screen first onto a concrete floor and I expected the worst. Picked it up and turned it on and to my surprise, the screen hadn't cracked. Used it for 5 minutes and it worked as it normally would. When I got back home and wanted to make a call, the screen wouldn't turn on. The lights for the buttons would light up but the screen would remain blank. Calls and texts would come through so the phone worked, just without the screen. After about 10 minutes of tinkering, the screen turned on and I heaved a sigh of relief thinking all was normal again. But when I locked it and tried unlocking it, the screen refused to turn on again. At this point I assumed there would be a loose connection between the MB and screen.
I took the phone to a few repair shops around here to find out how much they would charge and I got quotes around $200. So I decided to try taking it to the vodafone store to see how much it would cost to get HTC to repair the phone. The guy over the counter inspects the phone and finds no physical damage to the screen and says that they'd be glad to replace the phone right then and there at the price of me losing all my data as that would be unrecoverable. I told him I'd be glad to have a replacement on the spot. So in the end, I guess I got a good deal.
Lucky you !

I had the same problem last night:
phone charging with the HTC wallcharger, alarm set.
the device did not ring: it died during the night.
At first, impossible to boot (rom or hboot) or to charge it. I plugged it on my PC and the red light started to flash. One hour later, it was still flashing, so I tried to turn it ON
It turned ON but repported 2% battery only. (ok, that's why it was refusing to boot)
4 hours later, ON and plugged to the HTC wallcharger (that I verified of course), it was still 2%
After three reboots, plug/unplug several times, suddenly battery displayed 44% instead of 2%
Battery monitor repports that indeed, the device charged for the 1st part of the night, then suddenly and very quickly discharged to 0 while plugged, with no particular app to drain the battery.
During the 4 hours it was plugged and ON, it remained 2%, then a sudden 44% after a reboot.....
What the hell is that???? I've now cleaned cache and battery stats in recovery and I'm letting it charging to see if it goes above these 44%
Weird, I really thought my battery had just died....
EDIT: 2 minutes later, it now repports 46%, so seems to charge correctly. But I need to know what happened, I usually relay on my phone alarm to wake up, and if it happens again, it could be a real problem. Maybe I should flash an other recovery, even if I never had a single problem with it?

I have drained battery, been charging all night with a flashing red LED. No response. Now when I plug it in it still flashes red. When I hold the power button (also power+volume down) the main buttons start flashing white, but no response from the phone whatsoever.
When I let go the power button during the flashing, the lights either go out or stay on..
Any ideas? Thank you!
Hello,
My Xperia S which I bought in August 2012 doesn't boot anymore. A few weeks after I bought it, I unlocked the Bootlader and installed custom Kernels and ROMs and it worked fine all the time. I was on KA 22.1 SSpeed and Advanced Stock 17 and wanted to try something else, so I installed XZXperience 2 and the Elite V2-Kernel.
Well, after that, the phone worked fine but I noticed some heavy battery drain. Charging took waaay longer than usual (full charge about 4 hours with the plug) and the drain was immense. BetterBatteryStats showed me a Deep Sleep of 98 % while I lost about 15 % of battery life in ONE hour, that can't be somehow. The phone however worked still fine.
So I decided to flash the Advanced Stock Kernel again but the drain didn't stop, it was as before. I thought that the Battery Stats are maybe corrupted, so I let the phone discharge itself completely (didn't take long) and wanted to charge it fully. When I plugged in the charging cable, the first unusual thing was, that the red light appeared instantly upon connecting. Normally it would take a second or so. The second thing is, there was no logo, no battery symbol, just nothing but the red light when I plugged the cable in.
I slept a night and after I woke up, I disconnected the cable and wanted to start the phone, but nothing happened. Still, the only thing the phone does, is lighting red, when it's plugged in. Fastboot or Flash-Mode don't work, the computer doesn't recognize anything.
So...what to do? it appeared after I flashed the new ROM and Kernel, but I don't think it has something to do with them...the drain was also there with the Advanced Stock Kernel. Although I must say, that I often had flashing errors, often the device said something like:
format_volume make_extf4fs failed on /dev/block/mmcblk1p2
To me, it looks like the battery has a deep discharge and is dead, but I don't know, what could I probably do before sending it in? If the battery is dead the warranty should still be there, even with the unlocked bootlader, am I right?
Best regards
when you power on your phone what happen?
Ur phone boots while charging,but not charging.If this the case keep ur phone in ur hands for 10-15 min.Enter into recovery while led is pink.Flash other kernel.Else take the battery out charge it,enter into recovery flash other kernel

I can't go into recovery, because the phone does nothing, I can't start it. There's still warranty on the phone, so I'd rather not like to remove the battery...
ok so its no screen at all,
when u pressed power+volume up for 10 seconds does it vibrate?
Already tried, it doesn't...even after holding for minutes.

You could open the phone and disconnect the battery, or let the phone sit long enough for it the battery to die.
This will reset the phone.
Only problem is how long to let the battery die, as there is no way to tell.
Once the phone resets make flashtool ready to flash just the kernel, and use a rubber band to hold the volume down button in.
With flashtool waiting and button pressed plug in to PC.
It should give red led for about 10 minutes then flash.

Well, the incident happened a few weeks ago and after I charged it over night and it didn't work, I left it there for nearly two weeks and nothing has changed so far. In your post, you said, that you had to wait for 51 hours until your battery died but two weeks is quite long I think...
What do you suggest? I think, I'll send it in, if the battery is broken, the warranty should cover it.

Simple fix I think. This has worked for Xperia S and Xperia U. Both phone i brought as "DAMAGED". LOL. Battery is toooooo dead for the phone to detect it..... Use a wall charger to charge the battery up . I used a charger off ebay ($2 including post) that was for a Galaxy I9000 battery (old phone) and used wires and taped them to the battery..... Didn't even need to fully charge it! just like a jump start sort of thing...
Came up with the idea as at work we have to "jumpstart" car batteries to trick the charger into charging them
If you have a DC power source that puts out 4.2v at 350mA +/- 50mA then TRY IT and please let me know.

Well, I have a lithium charger for round-type-batteries, but we're talking about lithium here and if the battery is really damaged, it could be quite dangerous to charge it. The output of the charger is 1A, too, quite a bit higher.
I tried a last thing and took the battery out but it still only shows a red light while charging, so I'm going to try to send it in.
R: Xperia S dead?
IT happened The same for Me...
I was very worried..
I plugged to charge for 21h... Unplugged but Nothing!!
So i replugged iT and watched for 1H.. Suddenly IT Booted(But opened only logo Sony And Crashed!) So i Tried to unplugg and power on the phone but nothing.. No booted!!
So after 25m iT rebooted and like a furet i dropped my phone from The table and like a crazy tried to go in recovery.. So it Gone in Recovery i've Wiped ALL And Reinstalled Fw-Kernel.
So now i'm using The Xperia S

Thank u sooooo much buddy..
i got enough knowledge by this link, but i tried different tweak method to get my phone back with help of this link which you suggested..
I was watching some tv and wanted to check the clock on the phone.. No problems turned it off again .. Then 5 mins later i wanted to check facebook but this time nothing happened when i pressed the power button. I tried holding it down for 10 seconds.. Nothing.. Holding down volume down + power button for 10 secs.. Still nothing.. Then i plugged in the charger which also gave me nothing at all, not even LED's lid up! Plugging the device into my computer yields nothing either not even a "USB device attached" sound from the pc..
Is there anything i can do or did the phone just kill it self? I would also like to point out that the battery was around 50% when this happened..
Took the device apart and measured the voltage on the battery. 3.9 volts, so its not the batterys fault it seems. I've let the device aside without the battery plugged into it. Later today i will see if it gets back to life when i plug the battery back in, but im not gonna get my hopes up..
I had JUST replaced the screen on the device 5 days prior to this.... Why couldnt this have happend before i had changed the screen
Alright after placing the battery back into the device today and it still doesnt do anything my conclusion is that the device is simply dead unless someone else has suggestions.. What a shame
dude go to service and see what they have to say..100% is motherboard.

I ended up buying another cheap One X with a faulty battery and cracked lcd.. Took its motherboard, and used my lcd and battery and now the device is working again so yeah you were right.. It was the motherboard.. But i noticed that the motherboard i got was blue where the one that was not working was green.. Does this mean anything?
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.

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....

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....

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?

can you tell me a bit more? i've got the same problem, you didn't download any drivers and just left the phone alone?
So, the other day I accidentally dropped my Zenfone. When I picked it up, it had been shut down. I couldn't boot it up anymore after the drop. After like maybe 1 hour I opened the phone up and reattached the battery wire. Then I got it working. But then the problem was that the phone got really hot, even when I wasn't using it.
I waited until the battery was completely dead and then tried to recharge. And now the problem is that the phone won't charge at all. It still gets really hot. When I plug the charging cable in, it just vibrates, shows that it is charging, but then just after 20seconds it stops.
And now I'm asking, what should I do? I also tried to disassemble everything and then assemble everything back again, but with no luck.

inspect motherboard for physical damage with a magnifying glass. go for reflow if no physical damage.
