RED LED of Death - Guide to get phone back up and running

Hey all,
Surely at some point we have all gone to pick up our x10's and seen nothing on the screen and a blinking red led when you try to turn it on.
Immediatly thoughts of Phone Death and End of the World will undoubtably echo through our minds. Fear not!
Well, this happened to me on the weekend again (a few times now) so i thought i'd try a few different ways of getting it back up again and i think i nailed it first go
1. Yank battery out
2. connect charger and wait for green charging led
3. insert battery and wait for charging icon to appear in screen* (SE logo first, then Charging screen)
4. power phone on with cable still connected. Phone will boot as normal and continue charging.
5. celebrate avoidance of mobile technology isolation with a few cold ones
Hope that helps someone!
* For what its worth, i am running Zdzihu's 2.2 Beta4, but i think this should work on most. Only thing that might be different would be the charging icon does not appear on some ROMS. That i cannot answer but is probably worth a shot anyway

Hasn't happened to me yet. Do you let your battery get fully drained?

did happen that way once, was not anywhere near anything remotely power generating (camping) but this last time was still on 70% charge and on charge via USB at the time. weird!

Ok that sounds alarming. I'll keep an eye out for this on my x10

Hi,
I am facing the same issue as mentioned above but unable to resolve it.
I tried the steps mentioned:
1. Yanked battery out
2. connected charger and waited for green charging led
But for me the green charging led does not come up!!
What could be the issue?

I don't quite understand. Are you saying that X10's are just suddenly and mysteriously dying? I've never heard of this or had it happen to me on stock firmware. The way you described it sounds like you always leave your screen on. Maybe that's the problem, or it's because 2.2 custom ROMs are completely stable yet? :Confused?

sumtimes strange things happens
i charged the battery completly 100% den wipeout the battery
rubb it in my palmm ...insert it back
turn on the phone it says 3 % charged RED led starts blinking
ahahahahahahaha..
wipe out battery rub again placing it back it says 100%

Or it could be that your USB port is broken.

same issue...
i don't think usb is broken...coz the phone went dead when i was playing a game...there was no issue with the usb port then...
when i charge the RED light blinks...
if i remove the battery and place it back and swith it on RED light blinks again but for 3 times....and no display....
i've been searchin solution for this issue on sonyericsson support forums and xda support forums but no solution that i came across works...
does this mean that xperia x10 dies just by playing games? phone freezes and dies....weird!!

this was some time ago for me, and has not happened since, but i was thinking about it recently and i was actually thinking it was heat related. i was charging (at the time it died last time) via usb-pc connection, and that always gets really hot. maybe its a thermal heat saving thing?

You should avoid charging via usb on PC...it never charges battery properly and is recommended when you only want to charge your phone to do it via charger, not PC usb.

Where is the data on this?
I just discovered as of yesterday, that my Lenovo (IBM) Thinkpad T400 only has one good USB port as far as my X10a is concerned. The other 2 ports appear to connect, but the charge still falls down.
My best port is on the left side, further back of the two.
I am using rendeiro2005's [MOD/ROM)scamble_v01[CM6.1.3][30MAR]
http://forum.xda-developers.com/showthread.php?t=1015765
I am attempting a portion of the cycle of power as noted here:
http://forum.xda-developers.com/showthread.php?t=1010070
# Unplug Charger and do not plug back in until your phone dies
# Reboot into recovery once it is dead by connecting charger
# Wipe battery stats
# Charge to 100% and repeat the discharging, wiping, and charging process about 3-5 times
In attempt to make sure my battery was drained, I kept turning my phone on.
This led to my flashing red LED of death.
I attempted this workaround, but it didn't work exactly, but close enough.
I had to pop the battery out and in and disconnect usb a few times and back in until it started charging.....

yep, i generally do, but i was away on a trip and only had access to a pc/usb for charging (forgot my AC charger!)

Red flash of death:
For me it was because the connector on my phone(!), was broken.
So I send it back for repair.
A friend of mine had exact the same.
Vodafone is currently repairing mine, and made a photo of what was broken. ;p

i tried using these steps but nothing happened. the green led lights up but after a minute is goes out and then nothing happened.
what else can i do to turn my x10 on? i'm really losing hope for this phone. really disappointed. and i don't wanna say these but i'm starting to hate sony ericsson for not responding to these issue. i've read from different forums from different sites that a lot of same issue is happening to same brand and model yet all of these haven't responded even a single solution and that's really frustrating.

i have the same issue phone turns on on some point but battery keeps on 0% even if i charge it for more than 2 hours it doesnot goes past 0%..............I tried the genuine charger and everything

i am in the same boat. had more than 70% when mine died... now all it does is the flashing light thing...
i kno the usb port works b/c ONE time out of probably about a 100 that i've tried, it actually worked and brought me to the charging battery screen then immediately died again...
i can't seem to get the phone to go to xRecovery OR boot into flash mode...
this is all very upsetting... what to do?

Is this topic still alive.i v the same issue like other frends told.my x10 is dead.when i press power button it vibrates for less than a sec and then ..... no life.

[Q] Weird battery behaviour makes my X5 unuseable.. HELP!

Hi Guys,
Since a few weeks I have a weird problem with my u8800. The first thing I noticed was that the phone didn't charge properly; after a night of charging it would still not be fully charged. I thought it would be the battery that died (tho that would be a bit quick after half a year) so I replaced it with a replacement battery. This battery showed the same behaviour within a few days. Then I replaced the charger for another one; this kept things working for some time but eventually the problem returned. I also tried Wipe Battery Stats to no avail.
What's wrong? I dont't get it. If the phone's on the charger now, the red light is blinking. It doesn't charge beyond 3% so I can never take it off the charger.
I have Aurora ICS since a few months, keeping in pace with updates.
Any help would be very welcome cause this thing makes it impossible to use the phone as a mobile phone..

Install the official android 2.2 and see if the problem persists

Wipe the battery stats (in recovery). Afterwards try to fully reload the battery (even if it keeps blinking red) and keep it on the charger for 1-2 more hours. Then disconnect the charger and do not reload the battery until the phone turns itself off. Charge it fully one more time.
After following this procedure your battery should be fine. If wiping the battery stats in recovery does not work, there should be a program on the market which does the same.
If the procedure does not resolve the problem please send the device in for repair. If the battery charge does not go up to 100% after following the procedure please do the same. This is a hardware error.

Hi,
I wiped battery stats but charging won't go beyond 5%. What is the name of the app you talk about?

FORGET wipe battery stats, everyone knows that is placebo!!

I would do that, but it seems risky on a battery with only 5% accu left. AFAIK you cant do these operations with the usb connection as power source right?

Plug your phone to the charger (not usb) and you shouldn't have problems...

But how do I flash 2.2 without usb connection?

Format sdcard and put update on it with some adapter or go CWM > mounts and storage > USB mount.

Put update file into the sdcard/internal card, plug the phone to the charger, and start the update by simply press Vol+, Vol- and Power.
Simple

Sorry for asking, but is there any clear reason why you guys expect flashing 2.2 might help? I ask because I expect this will cost me quite some time and I am trying to see what my succes chance is.
And, do you think I would be able to go back to Aurora ICS after flashing 2.2? I wouldn't want te be stuck on 2.2..
Thanks!

Because 2.2 is the most stable rom/kernel. This way you can see if the problem is with your actual Aurora, or it's an hardware problem.
And yes, if you flash 2.2 you can go again to 2.3 and then flash Aurora ICS.
And please, read/search a little bit on the forum before placing those questions. Those questions have been answered a million times!

Not everyone knows that, at least I did not. I thought that maybe the ROM just wasn't showing the information correctly and therefore suggested wiping the stats. But if it does not work, forget it.
In this case flashing a different ROM won't help. A battery that cannot be loaded is a hardware defect - there has not been a single report that switching to Android 3 or 4 leads to this problem. The charging of the battery is only hardware-related (if it was software-related you would not be able to charge your phone when it is turned off!) and therefore the only possibility is that the device is defect.

This is wrong as I just explained. The charging process does not depend on Android or any software the OP could modify/change.

As I said, it is one of two: it could be a problem with Aurora installation or an hardware problem.
Install 2.2. If it is a rom problem, it should work right with 2.2 (it could be some kind of problem during the installation that have corrupted some files.)
If it is an hardware problem, it'll continue to have the problem. Simple

Please read once more; I stated why the Aurora installation has nothing to do with this. I cannot explain this better than I already did, but I'll try again if there is something confusing.

I don't have this problem with X5, but I've tried to fix it on a friend's other android model.
The behaviour was similar, the battery never goes to 100 % and can show from 80% 1% after minutes, and phone deactivated.
First I thought that was rom' s problem(had a CM7 custom rom), so I made a full wipe.
Problem doesn' t solved. After I changed the rom with another one(Ligux), but problem still there. Then I tried to charge it with another cable and without to power on. No difference.
So, I've flash the official rom. After that I managed to charge it normally until 100%. And seems that working fine now. The official roms change more things on the device than any custom, and seems that this problem caused from another part of the software which doesn't belong to system or boot.img(these are the parts which custom roms usually replace).

If you read the official PDF file that comes with stock roms it actually specifies that you should REMOVE THE BATTERY and connect it directly via USB while flashing the ROM So 5% charge is not even needed, just remove the battery and flash a stock rom!

OK, somehow the problem spontaneously solved itself and my phone worked fine for some time. But now it's back unfortunately. This time however I saw how it started. I think this is what happens: the battery goes too empty. So the phone crashes because of that (no proper shutdown). Then when putting it on the charger it sees the battery that is too empty as a faulty battery (indicated by the red blinking led, no charging animation visible). The phone won't power on.
There's a trick to get it to turn on though: remove the battery, plug in the power cable and it turns on. As soon as the Huawei logo appears put the battery back in (or a boot loop will happen). Then, there's a chance it will start charging again (though sometimes that only happens after many attempts).
Now the question is, why does it go too empty and is it possible to prevent this?

Phone wont lasted 10 seconds without plugging in ,But not battery problem.

Hello guys, this is my first time posting up in XDA and I am encountering a very weird problem with my N4
Disclaimer, the following is a long write but please bear with me and give a read.
Here's my problem after flashing the simple asop 29/5 build for mako. I come from same rom build 21/5 but i did a clean flash for the latest build. As soon as success flashing the latest build with gapps, then as usual will proceed reboot the system. Just right before the boot animation, the phone immediately went dead. I am sure that the phone is still left with 50%+ of battery at the moment.
Anyhow, I decided to plug it into charger. And voila, the phone now able to go through the boot animation and everything just fine. After setting up and restoring backups, I unplugged the charger, its 75%+ on the battery. Within 10-15 seconds, the phone immediately go dead again. I hit the power button and tried to boot up. Again, right after the Google logo screen, the phone went dead.
Commonly this indicate a problem with the battery. Yeah, but I went into recovery twrp and disabled the screen timeout & max the brightness. Guess what, surprisingly it lasted more than an hour which proves that this wasn't battery fault.
What had I tried so far, is just switched off the phone and plugged into charge for 2 hours. And obviously it doesnt solve the problem. I am backing up all the data at the moment and plans to drain the battery all the way down just leaving it screen on at recovery.
Anyone who know what happening with my n4 or encounter similar experience, please feel free to share the solution. Many thanks

Have you tried making a clean wipe and trying either stock or another ROM, to see if it works then?

Your test doesn't prove it's not the battery's fault. Flash back to stock, see if the problem persists and if it does then you know you have a hardware problem. Could be the battery.

Hello, much appreciate your reply. I flashed back to stock 5.1.1 now and yet this problem is still persisting. Thus pretty obvious thats an hardware faulty.
In another forum, a guy with Nexus 7 had similar situation as me, and he suggests that its the battery or the circuit board at the charging port went kaput.
Guess nothing else I could do right now, gonna send in the phone for repair and hope the bill wont cost as much as a used nexus 4

Bizarre battery behavior after replacing LCD, it's time to replace it?

I've read some similar threads about this problem. Most of them keep it inconclusive or ends with "replace the battery". Unless one damaged the battery itself, I find this rather strange.
In my, and most of the other cases, the phone will shutdown immediately: no warnings, no 'Shutting down...' message, nothing. Just like if the battery was plugged out from the phone. Then it reboots and can't get through the second boot screen: it shows the [Google] screen then shutdowns again. And starts to reboot again, endless loop until the battery is totally drained (which will take some hours). If I plug in the power cable it will boot the phone normally.
There are some confirmed actions that trigger the shutdown (always not plugged in the power):
- turn on WiFi (100% of the times)
- turn on Cellular Data
- sometimes when making a telephone call
- sometimes only by using the phone anywhere
When plugged to the power, the phone won't ever shutdowns like that.
Another symptom is the Cellular Network. Seems like every X seconds (around 10) the phone loses the signal, then 5 secs later it comes back - this is even with the power plugged in. I found it when people tried to call me, they said they try around 5x to call me, 4 first times the phone can`t be reached, suddenly it can. When the call is made I can talk for hours, the call never shuts down or anything.
Any clues on that? Anything I can test in here? It's really a faulty battery?
Just for info:
- 3yr old Nexus 4 using Chroma (Android 6.0.1), rooted. Battery worked 100% before the LCD replacement.
- I've already wiped Dalvik+Cache dozens of times, no difference.
- Wiped batterystats.bin, no change.
- At TWRP Recovery, sometimes the battery indicator also behaves in a weird way.
Some screenshots showing some bizarre behavior while charging:

I suggest flashing back to a complete stock LP ROM, use it for a while and see if the problem continues to occur. If it does, and since the phone is 3 years old (assuming you're using the original battery) this leads me to conclude that the battery is the likely culprit.

Hi there!
I know it's strange, but it's battery related I'm sure because I'v been there too.
I replaced my lcd first. Everything were fine for at least 2-3 days after that I've recongized some issue with my phone. For example the drained battery. Those symptoms were the same as you described in your post. (no connection, drops connection, sim missing, draining from full, etc)
One thing, i knew i fck'd my battery when I replaced the lcd and I had to remove the sticky-hardglued battery from my phone. I knew I've damaged the foil of the battery. Smell your battery! (if it has a phys problem you will know it by smelling it, damaged battery smells sweet-like)
Then I've ordered a battery as well and replaced it, but it has problems too. Phone didn't get charged and I was like crazy. The problem was with screws on the battery cable which is connected to the motherboard. I had to remove the screws from it and with some adhesive tape it just works fine now.
Good luck bro! :fingers-crossed:

Ok, you've practically described what happened with me when replacing my LCD too. That dreadful glue on the battery... I'm pretty sure I f*ed it up too. I was only after some confirmation, THANK YOU very much for telling your story. I'll replace the batt in here (and post the after story too, sure).
Thanks again! :good:

I have a similar issue:
1. Sudden battery drain, no particular pattern
2. Frequent Signal Loss (WiFi as well as Cellular) [My network provider usually displays a msg when I switch from Data to Wifi or Switch off Data, and I get around 1 such message every 2 minutes, even when I am connected to WiFi]
3. Excessive heating (No fixed pattern)
4. Yellowish marks towards bottom left on screen when Phone heats up

Hi, first of all sorry - I said I would post some feedback here after the battery replacement and never did. Ended up being completely solved by the replacement indeed. In my case, like I said before, must have been while replacing the LCD and then I damaged the battery somehow. If I was you I'd save some headache and go for a new battery, I tried to find answers for this everywhere (at the time I was really short on $) before finally accepting it. Today my phone works normally again.
(Note: about 4. Yellowish marks towards bottom left on screen when Phone heats up I really never heard/read about it.)

Phone not charging, stuck at 1% after factory reset

Hi everyone,
My Axon 7 is not charging at all after I did a factory reset. The phone is almost 2 years old and battery was degrading a lot so I went and decided to do a factory reset. It was at 50% and charging fine before I hit reset, but once I reset and came to the setup screen, I noticed the battery showed 1% which was weird. I then unplugged the charger and it immediately died. Turning it on without charger will automatically turn off.
The phone does show the red led light and charging icon but no matter what it will stay at 1%.
Here's what I've tried so far:
-Change cable/charger
-Left overnight charging with phone on
-Left overnight charging with phone off
-Reset phone/wipe cache many times
I have always been on stock A2017U and wondering if flashing another ROM may help?
If anyone have tips on how I can revive my Axon 7 that would be appreciated. I really don't want to retire it yet.

Two years? Consider replacing the battery? The degradation on this thing is horrendous.

Uh no.Even with degraded battery,it should not stick to 1%.

if i were you, i'd ignore this predatorhaze guy...
Whatever you do, I'd say go for it, buy a new battery. It won't be for nothing.
But on the matter at hand: This comes down to charging mechanics. Your battery will charge with a set voltage (usually 4.4V) after the fastest stretch which is constant-current fast charge. If your phone stays on, you should check a couple of things to be sure that the phone is trying to charge at least.
First of all download Ampere, it'll show you the charge rate and battery voltage. You should leave it charging for a minute with the app open, and check how much current goes through. The battery voltage should be reported below as well. Then disconnect the charger, and see if you can see what the voltage says. If it is below 3.3 V then BCL (Software that controls some battery-related functions, one of which is this brown-out protection that turns the phone off after a certain voltage) will shut down the phone. Degraded batteries have certain physical properties that make them heat more and have serious voltage dips when a sizable current is demanded, something which Predatorhaze here doesn't seem to understand.
Now, you could try to disable BCL completely by simply adding root to the mix and running some commands that Infy_AsiX posted in the BCL degradation thread, this is obviously temporary if your battery is past the point of charging but it's possible. no need to switch ROMs although that might not be as bad.

This happens to me too, sometimes. Shockingly enough, once I charge it via USB cable from my laptop (I have an ASUS ROG G750JS, if that matters) , the charging picks up. Moment it crosses 36%, I can now charge it via the wall charger again; I'm careful now not to let my phone die down anymore.
I should change the battery, but I'm planning on selling this thing by February anyway and want to give the buyer a new battery altogether, by then.

Here's readout from Ampere at 4.4v but the mA is very low. I couldn't get a proper readout after unplugging the phone as it dies immediately before it could measure.
Thanks for the post, will try to root and perform the BCL methods, if doesn't work ill try to flash LOS.
Just wanted to exhaust my options before replacing battery, seems tough to do and could be the motherboard or something else at fault.

Unfortunately this doesn't work for me either, I left it for a whole day while at work charging through pc, same symptoms

well, if anything, the battery swap is extremely easy on this phone
You don't even need to use heat on the grilles, just use something very sharp like a craft knife on the right corners of the grilles, pry upwards, then very carefully use a flat screwdriver or something like that. if you have the gold one, the grilles are very flexible, unlikely that you'll do any damage. If you have the gray model you'll need to be extremely careful with the top grille where you have the hole because it'll probably snap there.
Then take the screws off (6), open just slightly, take the fp cable sensor off carefully, take one more screw off, pry the battery, insert new one
You can watch JerryRigEverything's disassembly video to know every step of the process, it's useful for that

Finally I've managed to get the phone charging.
Flashed LOS but didn't remediate the issue, although TWRP does show 73%, phone dies after booting up.
So I attempted to go back to stock again. Voila this time turning on the phone, battery started to go up, unplugging holds.
However, issue remain is that charging now is significantly slower even though it is showing fast charging, and once it hits 75% it takes roughly an hour and a half to 2 hours to get to 100%.
I guess I will see how it goes for the next week or so and if battery performs poorly I will go ahead and buy a replacement battery.
