Hi folks,
First things first: I know there are a lot of threads concerning the "red light of death" for Huawei and other devices. I already read so many of them that my head is spinning xD However, I have some questions left and I need to distract myself from getting crazy due to the possible loss of data on my phone (and I have to wait at least until Tuesday for any news regarding the phone...)
What happend?
- Phone restarted while surfing
- Went into a bootloop
- Tried a soft reset
- Tried eRecovery --> Not succesfull
At this point I had to leave the train and the phone had turned off anyway. Wanted to charge the phone at the airport and back up recent data. Removed the protective cover and noticed that the battery was bloated. Since I was afraid I unplugged the phone and came to the conclusion that the phone doesn't work due to the defective battery. Back at home I ordered a new battery - didn't help. Phone won't turn on, softboot doesn't work. I only see a solid red LED when I try to charge it. Bought another battery - nothing. Went to a repair shop: This is the point where I start to have questions
They are all very nice at this place and maybe everything will turn out fine but I just can't wrap my head around certain things.
At first they also wanted to check for a defective battery and possible repairing errors since I replaced it myself. Today they called and let me know that the new battery is alright and they now want to order a new screen module. Later today I went to their shop to ask how much everything will cost and also to ask them about the procedure. I asked them why they want to change the display. Answer: Since the battery is fine, we believe the screen cable got damaged when taking out the old battery - its a common issue because the cable is underneath the glued battery. Once the new screen module is ordered there is a good change that it'll work and we can save your data. Note that I don't have to pay for the new screen, since I said that I only want the data back and that I don't need the phone back fully working. So I don't think they suggested it for the sake of making money.
I have indicated that I suspect a hardware problem, but the guy said the motherboard is fine. He continued to explain, that since the red LED is on and the mainboard as well as the battery are fine they assume a problem with the screen.
My questions:
How can they check if the logicboard "is ok" (I asked if they can do micro soldering and since they can't I doubt they can measure the components). Are there easy ways to exclude an hardware error on the board?
Is it possible that the phone doesn't start, vibrate, is not detected by the PC all because of a faulty screen? Any ideas why the LED is visible then?
Doesn't the red solid LED indicate charging? So how come I "charge" while not being plugged in? (LED stays red all the time)
My initial problem wasn't a possibly ruined screen cable/connection but a bloated battery. It just cracked the backcover open but nothing happened to the screen --> Is it possible at all that the bloated battery killed the display module?
If anyone has read this far: It would help me if you speculate with me about the problem, share your experiences or help me in any other way. Somehow I have to pass the time until next week and I'm going insane xD
Thank you so much!

Hi all,
I've spent hours researching and nothing so just looking for new ideas.
The last few days I've been running official SE 2.1 and today it started force-closing many apps. I restarted the phone a few times and that didn't fix it. So I restarted again to go into recovery and switch ROM. The phone switched off and won't turn on. It said it had low battery life if that's a part of it. The phone will not switch on, it will not charge with any combination of with/without SD card, SIM card etc.
1. SEUS and PC Companion will not repair it, they don't see it.
2. Laptop/PS3 don't see the phone.
3. I left the phone connected via the wall-charger for over 2 hours at two seperate occasions uninterrupted an nothing.
4. The phone shows no LED. Not even the quick-flashing red LED when the battery is extremely low.
I searched every SE site where this is discussed and no help, I've tried everything. I emailed SE and they said it would be better to send it away. I note that they charge a fee if they can't fix it. (It's within warranty though) and my phone is unlocked, debranded and shows various mods typical of users' phones from this site and the warranty says if SE find user mods they phone will void warranty. It may not switch on and neither the network or SE may find the mods which may mean I get past OK, but besides that, is there anything I can do myself? Thanks.
REPAIRED MYSELF
After hours and hours of research and effort, 5 minutes after posting this thread I fixed my phone myself. I hope though that this will help others out there. As with everything like this, especially on this site, these are user mods and frequently delicate or dangerous - you do them at your own risk, and could destroy your device or warranty. If you haven't rooted/flashed many times or don't know what they are, you do not know enough to do this. I say this to protect you, trust me.
If you take off the back cover, above and to the left there are two RUBBER coverings. I used a pin to remove the LEFT cover. You see the power connector of the phone to the battery. Use the pin, carefully and at your own risk, to remove the white part by gently pulling back and up. It's stiff so try a few times. You see 3 wires connected to the white tab. I clean the white tab and metal connector with my finger, re-attached the white tab, you must do that firmly or it won't connect, try again and again. Try the power button on the phone when you have it connected to laptop/pc/etc. and you should see the the red LED gently indicating it's slowly returning to power.
That was a hardware issue it seems?
I really don't know...I've seen other's recommend giving your phone a jump-start with a battery and connector but I couldn't find a connector, and just tried cleaning it with my thumb (no obvious cleaning needed, but I tried) and it did the job...strange. I'm sure this info. will help the next person who gets lost. It'll save time and perhaps money. And us guys around here like to fix things ourselves anyway...

Thank you very much!!!!My SE x10 mini now works properly!!!!great fix!!!!
You're welcome buddy! It's nice to be able to share advice with others!
i think,there is no need to remove back pin...
if you press home button simultaneously along with power button for few seconds phone restarts...i used to get same problem.
I've always been a huge sucker for good-looking phones, and the Luster White Xperia X10 has a great, unique look that isn't really matched or surpassed by any of the new Xperias, or any new phone at that.
So I got one... going by the eBay listing description, the USB charging wouldn't work because the USB port is messed up (which I prepared for by buying a AC charger)... but that aside it was supposed to work flawlessly.
Thing is, it doesn't.
As soon as I put a freshly charged battery in, I held down power and it vibrated like it was gonna turn on... and never did. Screen stayed black and I ultimately never got it to a functioning state. Been trying all kinds of desperate measures such as trial and error with USB insert angles to see if it was just "touchy"... and even trying to see if I could just get SOME form of response via recovery mode. And nothing worked so far. Sometimes trying to power it on makes it vibrate for a half second before it does nothing, and sometimes trying to power it on will just make it start vibrating endlessly unless I yank out the battery... but not once have I seen this damn thing power on normally.
The seller says he's quite surprised at this because, even when the USB charging officially stopped working, he was able to power it on and make a test call before the battery died (he did dodge my question about how long ago this was, which seemed a bit mysterious). The closest thing I can get to this phone showing "life" is that the LED indicator does blink red when the battery is completely depleted.
At any rate... he's offering me a refund... but I kinda just want to see this work.
What do you guys think? Any more tricks I could try to do to make this respond/test it, or should I just abandon all hope?
I would disassemlethe phone, unsolder the damaged portfirst -it might cause some power shortcut or even in betterlight ofbiewit takes the phone into some strange mode (eg. some resistance between pins can do this).
Or in the best way use the logic analyser connected on data links,but expectyou dont have one
Hello,
I have an unrooted Z2. With around 30% battery left, I put it in the charging dock on my desktop yesterday evening. After 1 or 2 hours, I noticed that the phone is completely dead - no LEDs are blinking, no vibration, nothing. I tried pressing the power button alone, in combination with VolumeDown, VolumeUp, CameraButton, for more than 30 seconds each. I tried pressing down the tiny red button next to the SIM slot for awhile. Nothing. Phone is dead like a brick.
The only result I'm getting is when I plug it into my computer (ubuntu 14.10) - the LED bar on top is showing a constant red color in this case. Doing the button presses outlined above in this situation is also pointless.
I'm installing flashtool for Linux right now, the connection is pretty slow and it will take awhile. I hope to find out more afterwards. I'm a newbie when it comes to flashing sony phones, only found out now about flashtool. Any advice/tip on how to proceed, or if it even makes sense to dig into this, is highly appreciated.
Thanks in advance!
Hello,
are you perfectly sure your dock was connected properly and it hasn't discharged your phone? Maybe there was something wrong with it.
I had similar situation while I was low on battery and I was creating backup in recovery. Then I fell asleep and I have found my phone completely 'dead'. I connected it to the wall charger and nothing. No led, no nothing. I have even connected it to my pc and also nothing happened. Then I connected my Z2 to the wall charger and I left it like that. And after few hours, out of the blue, just turned itself on, just like my old Nokia n95.
I'm sorry it's not quite solution you looked for, but give it a try. Essential is to charge it via wall charger.
Good luck!
Do what @amon87 says OP. Charge it on a wall charger for a minimum of 3-4 hours; If that doesn't work, can you specify whether you were using a legitimate Sony dock or a third party dock? If it was third party, it could possibly have caused a hardware problem with your device via the magnetic charge pins (not extremely likely but not unheard of). Worst case scenario, send it back to Sony in the next few days. The warranty will cover it if you haven't caused water damage or anything like that.
Thanks for your replies! I also hoped for a sudden discharge, so I removed the device from the dock, plugged the USB in directly, and left it overnight - still nothing. Also, I have the original Sony dock, and have never exposed the device to any water.
Found out the model number in the meantime, it's D5303, if it's of any help. Flashtool does not see the device, unfortunately. I just found out that Sony describes an option to restore your device through the official PC companion app - I'll give that a try when I'm home, and will report back tomorrow.
Otherwise I guess my only option is the warranty.
There's also an option to quickly plug in and out charging wire to kick-start the battery. Unfortunatelly i have no further ideas to help you out.
Don't give your hopes up, try again. There's been a thread of a guy whose Z2 turned itself off and it seemed dead, but after a day or two it just turned on.
So, of course it's also not detected by Sony's "Bridge for Mac" app. Plugging it in and out brought also no results.
As the device is still covered by warranty, and I have yet not tampered with it, I've sent it in for repair! My pocket feels so empty now, i wonder how life is going to be without a phone. Apparently they need 5 - 10 working days.
Thanks for your kind support, guys!
Sorry to hear that. Hope it will get fixed!
all key combinations have failed to produce boot and screen but the vibration responds quickly to the sequenced key combinations. no password issue always seemed to need a reset and extra attention but worked fine until left in partial sun through draped window and was powered on without a cool down. I heard a hiss and though the battery was discharging itself, tried when cool nothing so I put new battery in got a battery icon with low level and would not progress in power from there would not accept the charge . I charged with a new cube led usb charger and data cable overnight got the right results noted above but this time no icon just black screen I dont know what the power level is. I have tried three days charging nothing computer and wall. Tried to make phone vibrate and plug back in no. Windows phone one after mango, have lumia 710 zero problems removed battery twice to reboot phone twice in three years no biggie. Mango 7.5 on 710. want to use 800 as a data phone only would not trust it (mine anyway) for communication. Paid good price for it would like it to work again. Should I try powering it up for a few days? Oh phone always put on a surge protector as all my phones are. I once put phone under my pillow and a few hours later it booted screen came on. Have read people putting hair dryers on them I dont think thats the way to go got me here in the first place. very wonky phone it will and then it wont. I thought maybe usb connection damaged but obviously it is accepting some power and phone responding normally and readily to various key combo prompts but no boot and screen. How might this phone be repaired I would like to know what specifically could be the problem a base power or temp for reboot, what parts I could purchase (out of warranty) all parts inside were connected and looked pristine. No evidence of any heat damage. Used another Nokia battery for this phone new. This phone was let to totally power drain and what I have read that is not good for this phone. Maybe it is only accepting minimal power as before dont know but will try to charge another day to see if any activity occurs but would appreciate any help in zeroing in on what the problem or problems maybe, no software updates if no boot and it should do that if anything.
Sir,

Changed battery. Nothing changed.
Before I started this process, I was able to turn the phone on, hear the startup sounds, and charge it, no problem.
Yesterday I changed my cracked LCD (and digitizer) with one of these witrigs .com/oem-lcd-with-digitizer-for-sony-xperia-z2 (I'm not allowed to post links)
Followed the instructions provided by witrigs.
However, after having put it together again, when I try to turn it on all I get is 3 red blinks. (This would indicate low / empty battery, right?)
So I connected it to the charger (tried both wallsocket, and USB from two different computer, and different cables.) and all it gives me is a red light.
Normally, this would mean that it's charging, as far as I know, but it stays like that for hours, without any changes. So I was puzzled by this, googled to no avail.
I can not get it in flashmode, nor fastboot mode. However, here is the interesting part. When I disconnect the battery from the back and connect the phone to a charger (or USB from PC) the screen lights up, and shows me the charging animation.
In addition to this, when the battery is disconnected, I can get it into fastboot (Blue led, if I've read correct, I can not get into this with the battery connected.)
With this information, and my lack of real knowledge about how this technology works, I assumed the battery was broken, so to test that a bit further, I checked it with a multimeter.
It's currently showing 4.2v. I don't have another battery I can try with as of now, nor do I have other readings from other batteries. Maybe some of you do.
Anyway, have any of you encountered anything like this before? and or have any suggestions as to what I can / should test or try next? - I'm running out of ideas. (I will buy a new battery when I have money, but it probably will not be here in 5-8 weeks, due to when I get money and shippingtime.)
Thanks in advance for your time, and I'm terribly sorry if this has been talked about before. I searched, but maybe my searching skills are bad, as I could not find anything like this.
Please help
please help guys i dont know what is that
I have read some similar tread, not involving the screen replacement though, try to change the battery and it'll be up and running again. Keep us updated.
or if you have a multimeter, try to test the battery voltage and see if it's dead.
4.2 V means it's fully charged.It's either that your battery was severely damaged and the safety circuits inside don't let you charge/use it further or some other part of the phone is damaged.
