Had this today.. My middle battery contact was bent so i guess it wasn't contacting properely..
Took battery out, straightened pin and all is ok again....
Hope your is the same as it's easily sorted..
Yea, that basically means the phone can't charge. Be it because the battery has overheated, its a different battery, a contact is bent or dirty, or anything. It is related to not being able to charge the battery though.
i got this last night for the first time. my phone wasn't hot and never dropped or bumped. i just rebooted the phone and it didn't flash anymore...

oh! thats sound scary...
happened to me a few days ago i left it in my car for a bit it got hot so i figured thats what it was
battery got fried? or just dirty battery connection needs a contact cleaner?
This happened to me once, after "playing" a lot with Igo, the battery was extremly hot; so i cooled it down in the car putting my leo directly in front of the A/C exit, as it cooled down it stopped the blinking.
Had this happen to me a few days ago, noticed 2 things.
1) 2 pins on my battery connector were bent - attempted to realign them.
2) CPU was overheating while running multiple apps AND charging at the same time; seems to be a bad combo in the summertime...I could barely touch the back of my phone it was so hot.
I'd suggest that if you're running a lot of apps and/or charging the HD2 that you take off the silicone cover it came with (if you have it on). Even the fastest processor will get completely fried if it overheats, and I certainly don't see a fan running on the HD2
I've yet to have the LED flash at me again, but I can almost guarantee that these LEDs are flashing because of overheating or a bad connection.
Best of luck.

Same with my HD2. Had it twice this week running Navigon, Screen was set to bright, bluetooth on and phone was charging. Weather was hot, above 30 C and sun was shining from the rear directly to the PDA. And not to forget: My car is a convertible.. Phone was very hot and rebooted several times until I recognized the overheating. LED was flashing red and green. Does anybody know an app to control CPU temperatur or to 'underclock' CPU of the HD2?
I had the same issue today!
I believe it was because of the heat too.

Thanks great tool!
if you experience overheating, could you have a look here? I created a new thread to do some temperature monitoring:
http://forum.xda-developers.com/showthread.php?t=716288
I just had the same thing red green blinking. it was due to overheat. was sharing internet to my computer and it got very hot, now I put my phone top of antec twelve hundred's 20cm fan and it stopped blinking and got cool
And thank you for the answer why it was doing that because I got scared when it did that
I think it is battery issue, I experienced this once during USB connection with desktop(and several times with Touch Pro in car). These Li-Ion batteries have a circuit, which prevents charging when temperature rises above certain value. As mentioned in posts above, you can see this in summer, using navigation in car while plugged in to 12V. It is a normal operation of battery, preventing it from destruction from overheating. Simple solution is to have it cool down for a while.
Don't know how CPU usage relates with this(maybe the device takes more power from charger), but at least CPU generates also some temp, which warms the battery from outside...
I can always reproduce this error by uncharging the battery until the phone dies in android and then, start the phone and directly after that insert the charging cable.
I have no idea what this means but this is how I can reproduce it.
(If anyone wonders why I always uncharge it until it dies in android, it is because of some weird reason android doesn't show battery status correctly and dies around 10%)
Htc hd2 blinking red and green?
Hi everyone, a couple of this to possibly cloud the issue:
1/ I'd noticed bent connector pins quite soon after I'd received my HD2 - Figured they were supposed to be that way?!
2/ The LED/ Charging issue has, for me, started only recently. Even when the handset is cool (under 25c), no apps are running and the battery has 85% capacity remaining.
3/ Same issue on both of my batteries.
Stumped!
Even stranger......
If I remove the sim and charge while powered off - no problem. Turn it on? Flashing O&G LED again.

I just experienced the very same when my HD2 died while running Android:
I was checking the battery level - 13% - and suddenly the screen went black and I couldn't swich the device on again.
I plugged the cable in and it began to charge. I immediately switched the device on to see if it's ok and while booting and even inside WM the indicator was blinking orange and green until Android was running again - then it was only glowing orange and charging fine.
After 3(!) Hard resets the problem disappeared?
These were over a week so battery or software issue I can't say.
This was my question before I converted it into a tutorial:
Sorry if this question was posted before (I did ask this in the NOOB-FRIENDLY thread, but didn't get a constructive answer)
My Xperia Neo V dropped into water.
Dried it with rice for a whole day and turned it on. Success! Was able to even play games.
Then I sent it for charging. (Battery was 8%)
5 mins later, it died.
Responds by entering flashmode after blinking red LEDs (3 I think), so I flashed stock.
Still couldn't start, so I sent it for charging (No response either after some hours)
I abandoned it and switched to a Galaxy Ace...until now....
Connected it to PC a month later.
It blinks red LED continuously, unplugged it and plugged it to a charger. No LED response whatsoever.
Plugged to PC again and POOF! Magic.
Detected by PC as my old MT11i :'D
LED is green, can do file exploration. Buttons are lit, vibrates when I press shutter button. No sound with the volume buttons
So the verdict...
CAN I STILL REVIVE MY NEO V?
IS MY DISPLAY DAMAGED?
This tutorial was made possible by @xange and @georgeiulian89. Thanks!
Usually when you drop your phone, you would be doomed. Or so you thought. With this tutorial, you can save A LOT of money buying a new phone or repairing the wet phone!
HOWEVER, I CANNOT GUARANTEE THAT YOUR PHONE CAN REVIVE. THIS WORKED FOR ME (SHALLOW DIP IN WATER). YOU MIGHT ALSO NEED A NEW BATTERY (IF YOU THINK YOU CAN REVIVE IT)
Steps(suggested by xange, proved):
1. Remove your phone from the water source IMMEDIATELY! (duh) DO NOT ATTEMPT TO SWITCH IT ON OR PRESS ANY BUTTON.
2.Remove the battery, SIM and micro SD cards.
3.Dry the body with a dry cloth. Try not to use tissue paper as it will leave residue.
4.Disassemble the phone, all the way to the motherboard. I used a small slotted screwdriver (the one with only one edge)as there are screws shaped like stars. If you have that type of screwdriver you can use it. Similar disassembly video here: www.youtube.com/watch?v=ginuDIeNCs8
WARNING: INTERNAL PARTS ARE VERY SENSITIVE TO STATIC, METAL,ETC. BE CAREFUL. ALSO REMOVE THE CONNECTIONS TO THE FRONT COVER AND DIGITIZER (display) BEFORE REMOVING THEM.
5.Direct a blowing fan to all the internal parts to dry them. Keep the screws and parts in an accessible area. Leave it for 30 minutes. DO NOT DRY IT WITH A HAIRDRYER. YOU ARE JUST TRYING TO SCREW YOUR PHONE.
6.Reassemble the phone and insert the battery ONLY. NOTE: Make sure the ribbon connector is clean before connected, if dust (or any tiny electric conductor) sticks on the connector while connecting them, you will have high chancesof damaging the phone. Then, switch on the phone. If not,
A) CHARGE IT: Your phone battery might be 100% dead(until normal charging can't power it on). For me I pressed and held the Back button while plugging the charger into the phone (Flashmode). The LED should blink red and eventually, green. This is when normal charging starts.
B) REPLACE THE BATTERY: You'll need to do so especially when the (once)white area near the connectors of the battery has turned red, indicating battery damage.
C) SEND IT TO A (optional: AUTHORIZED) SERVICE CENTER: Out of luck. This is the furthest I can help.
ALTERNATIVE DRYING METHODS:
A)PUT IT IN RICE FOR A DAY: NO, Asians won't come to repair your phone. Rice acts like silica, which absorbs moisture like sponge. I suggest you disassemble the phone first as rice might get into the small holes around your phone.
B)SOAK IN ALCOHOL, THEN PUT IT OUT: Disassemble it first, too. Though I haven't tried this method, there are those who have proved it to work.
C) RADIATOR DRYING (suggested by georgeiulian89): I've turned it off,i've removed the back cover, took out the battery, sim card and sd card, and i've put the phone on the radiator (i've put a towel between the phone and the radiator and i've placed the phone on the towel). I've left the phone about two hours to dry, and then i've inserted back the sim, sd card and the battery and turned it on.
C)DRY IT WITH A HAIRDRYER: NO. RISKY METHOD. Water will evaporate, then condense back somewhere once you've done hairdrying your phone it will condense back. I tried it and it condensed on my phone's camera lens. (It's a hairdryer, not a phonedryer!)

What i believe is you've broken your battery and i didn't get anything what you asking about the display. It doesn't light up or what???

I dropped my Xperia Neo into water for 3 times, yet still operable, i mean, it survived 3 times of dropped into a pail of water, NO JOKES! .
What you should do is, the moment you dropped your phone into water, pick it out of water immediately, open the back cover and take out the battery immediately to prevent further electric short circuit. You will need some small tool to open every single screw to get the mother board come out (careful when unplug those ribbon sockets, if it breaks, you may have to pay to replace it) and dry (using hair dryer?) every single spot in the phone, except the screen, the screen should be tightly seal and should have no water enter into it. maybe the rubber physical buttons you have to take out and dry it too. (DON'T open the screen no matter what happen, unless water really enters the screen, or else the dust enter and stick at the screen you will have a REALLY HARD TIME { i mean it } to clean those dust out of the screen) confirm everything is dried and then assemble it. (from here onwards, it is a luck test whether you still able to save your phone or not, a line between hell and heaven) Put in your battery, It is normal you may not able to turn on your phone at first, give it a charge about 20 minutes and leave it there (red LED may blink repeat-ly for a while and you will not able to turn it on, just leave it) then switch it on, If you still can't turn it on, try change the battery. If symptom persist, god bless you, i tried my best helping you. ( it means it may not 100% probability to save your phone, but it is a way i did to save my phone)
Eventhough my phone survived dropping into water for 3 times, but it has some problems now, a random one, the phones get really really hot for no reasons for a short period (about 1 hour to 2 days) the heat comes from the motherboard after my inspection, maybe some water droplet enter into the chips and causing electric short circuit?
Good luck.

I followed a disassembly video for the Neo, but unfortunately the Neo V has a slightly different assembly, so I could not remove the screen to get access to the motherboard. Also, before I put it in rice, I tried to turn it on (Sony said it was water-resistant) after 12 hours in rice. The screen went all weird but I could hint the LegacyXperia kernel logo. That was before my phone booted up normally, and died upon charging.
For your heat problem, perhaps rust? Water should have evaporated from the heat and condensed everywhere in the motherboard.
Would soaking it in alcohol help?

I guess that it's a problem with the battery, not with the display (probably the battery has been short-circuited). I dropped my phone (Xperia Neo) in water 3 days ago. I've took it out after about 10-15 seconds (this was the time until i've realised that it dropped). The phone was still working fine, it didn't shut down by itself. What i did: I've turned it off,i've removed the back cover, took out the battery, sim card and sd card, and i've put the phone on the radiator (i've put a towel between the phone and the radiator and i've placed the phone on the towel). I've left the phone about two hours to dry, and then i've inserted back the sim, sd card and the battery and turned it on. Gues what: it works without any problem, just like before the incident. You should check the water damage indicator on the battery (it's a white strip near the connectors of the battery). If it's white, the phone don't have any problem, but if it's pink or red, the phone was damaged by the water. Mine it's white, with some very little pink on the edge (before it was completely white).

Thanks for the tip but in all-summer Singapore we don't have radiators.
UPDATE: After following steps by @xange to reassemble and charge my Neo V, it BEAUTIFULLY WORKED!
The catch: Battery calibration problem, stuck at 100%. I'll figure a way out. Thanks a lot devs!

To get rid of 100% battery issue, you might just want to flash stock ftf in the first place, give it a full charge and then flash your desired driver.

Hello guys!
So today while partying my Z2 fell in pool and well it wasn't really water proof as one of the side cover was removed, also the back cover wasn't very tight although I had a back cover on.
So when I took out the phone, It was dead. I removed the back cover, put it under sun and let it dry for a long time. Came home after like 5-6 hours, used a dryer on it and then put it on charging. The red light shows up and also the flashlight automatically turns on and it's constantly on so Idk what to do really. Any help? I'm thinking to leave it on charge for the night now

Possibly the flash light is short-circuited, so it's on indefinitely, and red blink is another signal telling you some hardware is malfunctioning.
Hi,
My friend gave me his Honor 9 which was damaged by water (snow).
Phone was dead but after cleaning it and drying and connecting to USB I can see blue LED lit where the earpiece is. The battery is dead. Now: is there any hope for the phone, maybe connecting new battery could bring it to life? I'm not sure if I should spend more time playing with it.
Some additional info: when connected to USB it draws 180 mA, trying to power it through battery connector doesn't do anything. When power button is pressed for ~8 seconds current slightly increases (0,5 s) then goes back to 180 mA - I suspect the reset circuitry or even CPU is alive. LCD is not showing anything. Telephone is not detected on USB port.
Thanks for any tips.

No hope!
Unfortunately no

Hi,
I had a Sony Z5 compact in a drawer for about 2 years, where the battery already was weak. I'd like to use it as a smarthome button panel where the bad battery won't matter, but I can't get it to turn on anymore.
When I first plugged it, the status LED switched to constant red. I unplugged it a couple hours later, just to find, that the LED stayed on even when unplugged. The device still was cold, so I don't think, that it really charged.
Since there was no reaction on the power button, I tried the "OFF"-button in the SIM slot. After reading on the internet, I held that button for 2 minutes. The phone vibrated every 15s, so it seemed alive. I then plugged in the charger, again the status LED turned constant red. This time the device got warm, seemingly charging.
After a couple of hours I tried starting it, but still, theres no reaction on the Power button. I again tried the OFF button, with no reaction whatsoever, not even vibrating anymore. Also the status LED shows no more reaction on plugging it in.
Is the device dead now? Anything I can try to get it working again? I don't need the battery anymore, Its supposed to spend its second life permanently plugged in.
best regards,
RockNLol
The usual advice is to make sure it is off (Hold power and vol-downup until it vibrates 3x / if really dead, just wait ~20s), and then leave it on a charger for a few hours. If that doesn't do it, your battery is toast.
Even if it is revivable, there is a chance that it is so weak that it will make the phone crash - the battery is used like a buffer even when on the charger, and if the phone needs high peak current, it will try to take it from the battery. If the battery is too weak, voltage will drop and the phone will crash.
In any way, I would not want a battery that is potentially damaged to be at the charger 24/7. If you deep-discharge a battery, it can form tiny little short circuits, and if you charge it, it can become a fire hazard. As in, burn your house down and release lots of toxic fumes while doing so.
If you are familiar with soldering, the best solution would be to open the phone, remove the battery, and replace it with a fake battery circuit. Obviously, don't do this if you aren't comfortable doing this kind of stuff, and always have a plan for what to do if the battery decides to light on fire.
For that, after you removed the battery, try to pry off the yellow tape on it, and get to the battery protection PCB near the connector. Carefully cut the leads to the actual battery and remove it (this is the most dangerous part). Then, solder a large capacitor across the battery leads and a connector for a power supply that can provide around 4V at, idk, 2-3A. There aren't many 4V power supplies, but a 5V one and a (silicon) diode in series work well (make sure the diode can survive a couple amps). Then, plug the fake battery back into the mainboard, fix everything in place using tape or glue, and see if it boots.

The usual advice is to make sure it is off (Hold power and vol-down until it vibrates 3x / if really dead, just wait ~20s),

Power and Volume-Up?
Sure, one of the two
Power + Volume-down starts TWRP when the device is not running.
When the device is running, it takes a screenshot.
