Xperia X10i Won't Turn On. - XPERIA X10 Q&A, Help & Troubleshooting

Hi,
My xperia x10i is not turning on from months. It all started when the phone started to reboot too much like every 2-5 mins so I removed the battery for some time when I putted the battery again it was still booting up but same problem rebooting after 2-4 mins then I reflashed the original firmware (battery was only 7-15%) it successfully flashed and then when I tried to boot the phone, it wont boot and only give me 3x red led flashes, I knew my battery was drained so I ordered a new one as the previous one wont even charge from a wall charger. So when I tried the new battery it still wont boot it only shows 1x green led and vibrates but nothing happens after that, I again tried to re flash the software with seus but it wont work (After downloading of software installation failed) I tried to flash it with latest version of flash tool but it failed to so I downloaded an older version on flash tool and it worked but still the same problem 1x green led and vibrate nothing else on screen.
I am dying to see the Sony Ericsson logo on my phone >.<

Could be hardware issue. Maybe it’s about time to upgrade..

Hi mate -
First you need to make sure your battery is charged
Plug into your charger and if your led light is red just leave it to charge it should change colour from orange to green Charged :good:
Try flashing with flash tools again a FTF rom eg - [ROM]"X10S" |v9 Final released FTF File| 21/07/2012 |xperia s firmware ported to x10
Link - http://forum.xda-developers.com/showthread.php?t=1516960
Download the ftf file open flashtool and drag and drop FTF file into Flashtool
Make sure your tick no final verification box or you will get errors. :good:
It will prompt you to plug in your phone. Hold back key then plug in usb to computer OR you can take your battery out and leave your phone plugged into computer with usb then hold down back key then put your battery in.
Hope this helps

Trying.

I had the same problem. The battery just could not hold the charge. You can try to freeze the battery and put back. If it can turn on, get a new battery. I found one on internet only about $5~6. It works with the new battery.

Maybe you need a new battery

I had a similar problem at one point the battery was completely drained the x10 has a flaw in order to charge the battery there must be enough charge to power on the handset I cut a pkyg off a charger taped the wires to the battery and left it for 30 mins. Its dangerous I know but it did work.
Freezing actually reduces a battery's capacity (while its cold)by as much as 40%

You must charge the phone before flash it. If you cannot charge it, put your phone in flash mode and plug it to your computer. The flash mode lets your phone charging
You can try to flash it : https://docs.google.com/file/d/0B_d8uWGbkaetVUw4bldBVzV1ZTg/edit?pli=1
It's the official 1.6 FTF for X10 and it works on locked and unlocked bootloaders

X10 bricked Help Please

Hi friends,
I think I have bricked my X10i B'cuz the phone is struck at the Sony Ericsson logo.
What I tried to do?
I was in tripndoid MIUI, so I wanted to upgrade the rom to black edition, so I tried to unlock the boot-loader, I had successfully downgraded the firmware and unlocked the boot-loader and also updated to custom kernel (doomloard)
After that I got in CWM recovery mode and installed the .zip file after cleaning the system cache and dalviks cache, Now the phone refuses to start nor get into flash mode.
I tried removing the battery and reinstalling the battery, but as soon as I put the battery back on the phone lights up at the Sony logo.
Even If it try to charge the phone from the electrical socket, the led of the phone does not turn on, it still gets into the Sony logo and stops there.
The phone gets recognized in the flash tool, its tells the phone is in ADB mode. I cannot put the phone on flash mode anymore.
I tried looking in various threads, but could not get a concrete answer, please help. I have limited access to internet, So i do not have PC companion to try and repair my phone. Is there any way that I can get back my phone alive.
Edit: I just plugged it in, I can get into flash mode.. Anyone please help me how can I flash back to any rom..
Did you flash the upgrade firmware after downgrading and unlocking firmware? Sometimes the Kernel doesn't support certain ROMs as well and it can't boot into the system.
The easy method of flashing the stock SE firmware is by using the X10 Flashtool. Simply download and install it (you might have to turn off anti-virus software as it's listed as a virus of some kind) and install the stock SE 2.3.3 firmware and press flash. Instructions will pop up and your phone will be as good as new. It does mean that you lose everything like ck, recovery, unlocked bootloader, etc.
You can find the Flashtool and the stock firmwares here:
http://forum.xda-developers.com/showthread.php?t=920746
EDIT: To do flashing, you will have to turn the phone off. The X10 may turn on when you reinsert the battery too soon, like you have described. Generally, you should take the battery out for about 5 seconds before reinserting it so the phone actually turns off and doesn't turn back on.
Good luck and don't forget to hit thanks if this helped in some way
@ Panzerfaust101 - I have already hit thanks
I figured it out myself.. here is how I made it through..
Problem - was in the Kernel, just out of some instinct I downloaded Doom's kernel v.006 and some how got the phone into flash mode and flashed the kernel.
After that I was able to navigate into recovery and install the new ROM, but my problem did not stop. Now the phone got struck in the new RoM's startup screen.
So again I downloaded the right version of Doom's kernel for the RoM and flashed it again. So I got the problem solved, but I realized the phone radio was not working, So I again downgraded the firmware and ran the bootunlocker and then updated the phone back to the right kernel.
Now I am able to enjoy the new ROM.
Yeah, it should be your ck. I flashed a ck before (can't remember which one), but for one reason or another, I couldn't get cwm-based recovery working, so I tried another one which couldn't boot anything up properly, so I'm back on stock 2.3.3 (was on the MIUI-based BlackHD Edition. Brilliant ROM btw) waiting for beta+ CM9 ROM for X10 to be released
Btw, for future reference, can you link me the exact Doom ck that you used? I'm probably going to install a custom ROM on mine again and I need to know one that will be guaranteed to work without a problem. Thanks
Cool, you will need Doom's kernal - X10_FXP_DooMKernel-v05a-BootManager-v1.3
Also hope you have the bootlocker unlocked, if not you need to use X10_aZuZu_Kernel_Downgrade_Generic firmware and unlock the boot loader after that you can directly upgrade the firmware to Doom's kernel and install the RoM.
Thanks to DooM and aZuZu for the files.

i've your same problem...how i can plug-in in flash mode?
Try this trick!!!
Remove the battery.
Connect your phone to system with the battery still out.
Now hold the back button and put the battery on, green led will glow.
Now you are on flash mode and this would stay for not more than 5-10 secs
You should have quick fingers, so that you should select the firmware or any update within those ten sec's. Keep trying this will work... BTW its was the only way I could revive my phone.
but pc don't recognize my x10...

Is that the method you use to flashing? I've seen it quite a lot on these forums, but I haven't personally used it before and I've been curious as to what they did. Generally, don't you prepare to flash by pressing the flash button on Flashtool and following the instructions that pop up? i.e. disconnect and turn off phone, hold back button, reconnect phone. I've always used this method for flashing. Doesn't it work properly for some devices?
Also, if the battery's out and the flashing takes 10+ seconds, what happens? does it stay on once it's detected a device flashing the firmware?

The ten seconds isnt a standard just a rough idea. Yeah the flashtool way is proper way to enter flashmode it just that the USB socket on this model isn't the best, many people had problems and basically just found their own way around it.

Pleeease, I need help.
My x10 enters in flash mode with the green led, but it still only 10 seconds on, after that change to SE logo and that's it...I think that it's because it ran out of battery...any solution for this!?!?
After that I can leave it connected by USB but still being with the SE logo and it doesn't seem that the battery is charging.
Even if I take off the battery, put in again and simply connect it by USB the SE logo shows again...I don't know what else to do...

Kind of a late reply, apologies for that. Yes I followed the same method as listed. Some times your method works but not always!!!
If the battery is below 5% i believe the system will not get you into the flash mode. Since flashing hardly takes few seconds, I suppose the available battery will hold on.
BTW my trick starts only after I get into the flash tool

I don't think its cuz of a battery issue, It cuz of kernel issue. Kindly give a backdrop of what you are trying to do? Might be helpful to correlate the actions.

Yes mate I tried the same tool that you have posted. Yeas I did upgrade the firmware to custom kernel and then went ahead with the installation.
Try this link : http://www.mediafire.com/?3ol6gpykaa5acwo
Thank 7hr08ik for this link. Please use the FXp kernal, not DooM.
Major update is that DooM kernel version that I had installed was completely a phone crasher, So I had to update the kernal and the RoM for a newer version.
Right now I am using FXP kernal with v3 of the blackedition HD v1.3 RoM, So far So good

charging in flash mode?

Hello everyone:
I just updated my rom to CyanogenMod and everything was great.
after a while my x10 stucked and I removed the battery and put it in again.
Unfortunately, (and don't ask me how it happened) the phone became a brick Which is usually not so bad because I can always flash it and put the Generic firmware (As I did before).
But this time it's a little bit more complicated. This time my battery is dry.
And now I cannot charge it (because it's a brick)
When I try to flash it anyway it says:
ERROR - ERR_SEVERITY="MAJOR";ERR_CLASS="SECURITY_CLASS";ERR_DYNAMIC="SIN header verification failed"
Click to expand...
Click to collapse
And now I don't know what to do.
Is there anyway to charging my phone when it's a brick... maybe in FlashMode?
Thanks,
Asyagasy
Oh, P.S:
When I say it became a brick I mean that it vibrates when I press on the Power button but the screen black.
As I've already said it happened before - and I could fix it by flashing it to the Generic rom.
sorry. i don't know how to charge battery in flash mode.
but there are lot of cheap external charger for x10 battery.
!!
The error which you get is because you are trying to flash a kernel which requires an unlocked boot loader. I believe yours is not unlocked.. Unlock the BL and you'll be fine...
Well you can flash in flash mode.. load a new kernel, that should allow it to enter its charge state

Xperia U won't boot. Help needed

Hello.
I have rooted the xperia U using the flashtool by following a guide available on xda. Everything worked fine. I wanted to install a custom rom for which I had unlock my bootloader and flash a custom recovery for flashing the rom. I downloaded and flashed cwm. So I unlocked the bootloader using the official method, i flashed the boot.img of the custom rom(in fastboot) and tried to go to recovery, but my phone wouldn't switch ON now.
I was able to make it reach flashboot mode(green) and tried flashing ftf.. Even that's not working.
The service update software is not even detecting my phone.
Please help.:crying:
When you say, not switching on, can you feel it vibrate when you push the power button?
Also whats the error you receive on flashtool?
Yes, i do
But the screen is blank and I can only see the red notification light

May be you flashed wrong kernel, which is not for your phone.
Try to charge the phone for a few hours and after thats try flashmode again to flash stock rom...
same problem
Actually I am facing the same issue u had with your Sony xperia u. Please help.
Charge the battery, seems gone flat. Leave it on charge for half an hour or so. If that doesn't work maybe the software is corrupted to the point it doesn't cold boot to charge, so charge battery separately using external charger for half an hour or so. It should be able to boot at least to flash mode (Vol Down + Power).

Sony Xperia Z2 OS Deleted, Stuck on Sony Logo

I deleted my OS in TWRP recovery, I've tried doing many things but none of them have worked. I tried flashing a stock kernel using fastboot, flashtool, using sony's flashtool Emma but all of them gave an error. My bootloader was unlocked and i think USB debugging was on but i can't be completely certain. And I'm not sure if the phone is charging or not because it's just stuck on the sony logo.The model is D6503. I'm pretty new to this stuff so i don't know what to do, if you need any more information i'll try to provide it as fast as i can. Thanks in advance.
Do you still have access tp TWRP? If you do, just go into the recovery flash a custom rom from XDA then try to return to stock if you want.
Are you have done a flash thing before?

Yes I have used flashtool before. It gets stuck while flashing data and doesn't move on any further. I left it running at night and when i came back to it 10 hours later it was still stuck on the same step. Maybe it's a battery problem and it runs out during the procedure, but i can't check the batterly level because whenever i try to charge it i get the sony logo and it stays stuck like that. I tried the red button at the side next to the SD card slot but it just vibrates 3 times and then turns itself back on when i plug it back into the charger and gets stuck on the sony logo again.

My battery life is pretty bad overall it especially drains really fast after reaching 15-30%. Yes I can still connect to fastboot and flashmode. I've tried using both to flash a stock rom/kernel but both of them gave errors.
When I try to use flashtool it gets stuck at some point and doesn't go any further. When i try to flash using fastboot i get an unknown error within seconds and it doesnt work.

Strange... It can be the battery because if you can connect to flashmode/fastboot mode this means phone is still alive. I also had a battery isue too which didn't let me boot the phone at all. Anyway you should leave your phone on charge for overnight then try to flash something next day ornif you can someone open the backcover of your phone you can try to dissconect the battery and boot the phone while connected to charge but if you don't know how to open it please don't do it.

Hmm strange... I am sure that you can't get into flash mode without the battery. But I am kinda sure the problem is the battery becuase when my old battery died my phone just kept blinking on Sony XPERIA logo. Anyway I think you should get other's idea as well.

Help! Xperia Z2 (D6502) Phone not booting. (Battery Problem)

My device is not powering on because it shows that the battery level is low even though it's not.
A couple days ago my device just powered off without a prompt or anything. I was using my browser and all of a sudden it powered off. I tried to turn it on but got nothing. Then I connected it to the charger and the display showed the battery icon and the LED showed red. I tried powering on then but it wouldn't start. The Sony logo would come up and then go off again. This happened a couple times and I connected and disconnected it from the charger a couple times and after a moment it started normally. It happened again later but started back up after connecting it to a charger. The next day it happened again with the Sony logo showing and turning off again continuously and all the while the LED is red. Blinking red twice, showing the battery icon, then the Sony logo and turning off again. But now its not showing anything. I connect it to a charger which shows a red battery icon for a few seconds and then black screen but with red LED. I had LineageOS rom installed so I thought to flash stock ROM again which might solve the problem but now I can't get the device in flashmode to flash the ftf.
(IDK if this is relevant or no but a year and maybe half ago I had a problem with the battery. The phone took about 5-6 hrs of charging and discharged in 4-5 minutes. I went to the service centre and they told me it was a software problem which they fixed.)
Can anyone suggest on what to do? Any help will be appreciated.

this might seem irrelevant but trust it isn't, if you have the TA partition already backed up you should restore it, when you do your problem would be solved, I had same issues, and it turns out that the TA partition contains everything the phone should do to boot up, and what to do, its like a blueprint that the phone follows, I restored the phones TA partition and everything was fine again, flash advanced kernel TWRP via fastboot in flashtool, and instal a stock firmware from there and as soon as you can boot the phone in the system restore the TA partition and flash stock ROM via the Xperia Companion, Thats exactly how I solved my issue

Well, thanks for the response. I'll be without WiFi for a couple days and will try your method then. I'll let you know if it works out.
Thanks again!

Okay. I restored the TA Backup, flashed stock firmware but now the device won't boot up. It's stuck on that blue wavy screen. I waited for about half an hour but no change.

1. hold the off button and the volume button for atleast a minute. (ignore any vibration)
2. charge your phone until the green light turns on. (make sure phone is off, don't charge while its on the blue screen)
3. turn on your phone

are you rooted or on pure stock ? if you installed the ROM using flashtool please go to Xperia Companion and try, if not unlock your bootloader again flash Advanced Kernel, and flash a Custom ROM lets say (RR 7.1.2) and see if the phone boots up

Flashed RR 7.1.2 but its stuck on bootloop. Same with Carbon Rom. Only lineage seems to work.
Any ideas?
Edit: Installed RR again.. it booted up
