UMI Z dead... only red light flashing slowly - UMi Z Questions & Answers

As stated in the title, my UMI Z is completely dead after 1 and a half year of usage. Nothing happens if I try to power it up, only, if I plug it in, the notification light flashes red slowly. I already opened it and checked all connectors as well as the battery voltage etc. Everything seems to be correct. The only thing I could think of causing the Problem is, that I dropped the phone the day before, but after it, it did work normally. It isnt recognized by my Computer anymore, neither can I flash a new ROM; and yes Ive got the Drivers installed and followed the instructions word by word… Does anyone of you know a solution? And please dont care about grammatics and spelling too much as I am no native Speaker UPDATE: If I push vol up and power and then insert charger the red light stops blinking until replugging. Also my Computer is now recognizing my phone as unknown USB-Device altough ive got the Drivers installed

It's duplicated thread.

[Q] Xperia X10 won't turn on.

Hi. The phone application was not functioning well and the F/C dialog showed up. I powered off the phone and from that point, the phone won't turn on.
The battery was fully charged before this happened.
When I press the power button, the phone vibrates for half a second, the screen brightens up but does not show anything but a black screen.
I removed SIM and SD cards, removed the battery and performed the above steps but nothing happened.
I also tried to put on the charger to see what's going on. Once I plug the charger, the phone's screen brightens but shows only blank (even without pressing the power button)
When connected to the charger, the green light for charging is on for some minutes, then goes off automatically.
I tried to connect it to the PC, and PC Companion finds the device as usually. It even shows the dialog on the pc screen to mount the device.
I tried a hard reset, but does not work
On some point, the sony logo appeared and then a dialog saying: "sorry process system is not responding". The first time I pressed Force Close and the phone turned off. Immediately after that, the phone turned on and showed the exact message. I pressed "Wait" but nothing happened in the next 15 minutes.
I called Sony's support center and they suggested a software update. Did the process exactly as it should, but again, even after the software update the screen shows nothing but black. It is all the time brightened for some reason.
I tried to turn off the phone for some time by removing the battery, but as soon as I put the battery back on, the phone's screen brightens and stays that way forever.
The phone was functioning perfectly up until this issue. The only application I had installed apart from some games, was AWDLauncher. On the screen I had only a TASK widget and a battery status widget.
The phone is 3 months old and has been always in perfect condition.
ANY help would be appreciated!!!!
Many Thanks
Try to format phone with this method hope it should work as it seems the issue is with OS only ..

I tried the steps found in the link you gave me, but I couldn't go any further after step no (5) from the tutorial, as it would require to enable Debugging mode and I cannot access the OS (since the device won't turn on).
Is there a way to format all the contents of the device and have them replaced by running SEUS (as it always says that my device is up to date now)?
Was it this:
http://www.sonyericsson.com/cws/sup.../detailed/updateservice/xperiax10?cc=gb&lc=en
That Sony Ericsson told you to do?
If not, use that.
Download it, follow the steps when it says you have the latest version, press "Install Anyway".
Hope this works.
Hi itTim. thanks for the response
this is what i did but no improvement at all ((
Sounds like you broke your LCD screen somehow.
That would suck because I broke mine and it cost me $200 to fix.
Hi Hypercore.
Yes that could be the problem. The thing is that I always took rally good care of the phone, always carried in a leather pouch and never droped it. How sensitive is this lcd anyway?? Did you notice any cracks on your lcd or was the problem simillar to mine?
Thanks
When you turn on the phone does the lcd backlight turn on?
If so, look for any faint lines of color (usually a hairline size). If you see any of those then your screen is cracked.
the backlight is on, but there are no lines of colour on the lcd screen.
another weird thing is that the green light on the top blinks one or two times every time i put on the battery. even if the phone is off, once I insert the battery turns on automatically after a couple of seconds.
If all else fails you could try to flash back to your original fw with the tools here:

That won't do anything.
I had almost the same issue. Nothing worked. But, when I removed the battery and left it for a day (24h) without it, it just started working again. Still working without issues..
Good luck!

Phones are very wierd pieces of technology. I once bricked my k610i and that's a phone that's supposed to be impossible to un-brick, but out of nowhere a month or so later i picked it up, hit power and it turned on perfectly. Made no sense at all, but it worked.
Taking the battery out for a long time probably took all the electrical charges from it (kind of like how a computer power supply / monitor can hold power charges) and reset your handset.

Indeed. It could be a frozen chip, memory fault, power-regulator and so on.

if you have done this and did not worked , then it is the LCD.
send it to workshop and check it there.
Guys i Really need the solve of this problem , my xperia has blank screen now without backlight and the phone completely doesn't work . when i put the battery and prees the switch botton it gives me 3 red signals , i've updated and hard reset but it didn't work , and btw the LCD is fine , any idea. did removing the battery worked???? . please answer
After a looooot of time since my latest post, finally my Xperia came back to life. There was a battery failure which means the phone was ok all the time. Weird thing is that the led light showed that the battery was charging ok. I removed the battery and after a lot of time it is working ok again. This was really really odd.
FYI for anyone else that gets this issue.
I just had this for the past hour after trying to change my baseband....could not get it back for anything.
What I did finally try was run another baseband via flash tool, connected to usb and it started flashing....after flash phone powered on again...yeah I agree with everyone, that is freaking scary when it happens.

Big uh-oh...

I have a problem with my x10i.
I was trying to use the flash tool for 2.1 from binary's thread but I failed and it was still 1.6. It got to the point where it said [finish] and then error message in the cmd. After that I tried using SEUS to update it again, the 2.1 update was available so I tried installing it.
Here is the current situation.
After installing 2.1 from SEUS, I followed the instruction to turn the phone off/take out the usb. After turning it back on, it's been half a hour and I'm still stuck at the blank screen before the SE logo shows up. I tried taking out the battery to boot into Flash Mode but that didn't work either. I was wondering if it was because the battery is near empty, but that's not the case since I was using the wallcharger for another hour on it earlier whlie it's in the blank screen state.
Can anyone point me in a direction for fixing it?
Forgot to mention, holding the power button doesn't turn it off either. I would have to remove the battery to turn it off.
Try a re-flash... use the repair function on PC Suite
the usb cable isnt turning on the phone by connecting to it while its off. i can't boot in flash mode either .
had somewhat a prob yesterday like it, my phone did turn on again. i got an other pc installed companion suite there and repaired the firmware(said it was up to date) and then after the boot i'am @ 2.1
was the other pc a 32bit? because the first time i tried using seus was on a 32bit then i bought 64 bit computer.
I'll try running it on a 32bit computer today.
Okay, so I borrowed a PC and installed PC Companion and tried to connect the phone to the computer. However the computer didn't recognize my phone at all. Perhaps this is a problem with window 7?
I also noticed that when i take the battery out and put the usb in then the battery back in, the green LED light stays on. It stays on until the phone trys to boot itself on then the LED turns off but the screen turns on. Only thing is that the screen is still blank and never went to any of the logo screens. And while the USB is plugged in, I can't turn it on by holding power. However if the usb is not plugged in, and I take the battery out and put it back in, I can hold power and it'll blink really fast for the green LED and then the phone viberates for a quick second (like it usually does when you turn your x10 on) and then blank screen and nothing else. The reason i can tell it's on w/ a blank screen and not a screen issue is because I put the phone under the table (very little light) and I can see the screen dimly lit by the back light. These are the only 2 indication I have that the hardware is working.
My biggest guess right now is that the firmware was F'D during the flash or the loader is now a goner since I can't boot into safemode or flashmode. My other conclusion so far is that while the phone is on (confirming it being on via the backlit blank screen) the usb connection goes off. Perhaps its stuck in a loop? Can anyone tell me how I can fix this?
I did searches as well.
I came across people who said their phone was stuck so they let it drain out the battery on it's own and it unstucks. Some say they waited 4-5 minutes and it worked.
So far the longest I waited was:
3 Hours(And counting) *usb & battery is plugged in but charging green LED light is not on*
or tried to leave it alone for 8 hours without battery or usb plugged in.
I'm hoping someone has come across the same problem and had a fix or one of the DEVS might've experianced this problem while trying to test their loaders/etc?
Nothing to do with Windows 7, I and others have no issues on Windows 7 x64. Run the attached file and delete anything to do with SE and try reconnecting in flash mode whilst running SEUS. Post a screen shot of the program if you're unsure what to delete.
Okay right now I am on the 2nd computer with the 32bit OS that I tried to connect to earlier. However i was unable to find a DEVID that was registered on Nov 1. which should be the case since I have never connected my phone with this computer ever before.
I was unsuccessful at booting into flash mode as well. I would put the battery in. then hold the back button and plug the usb. However the phone would not auto boot like it does normally when you plug in the usb so I held on till it did because I thought it might be lagging, however it still didnt boot into flash mode.
I have a baddddd feeling now
Did you read my post?
this is the screen shot of the program you told me to run. It was ran on the computer that I borrowed today, it was never connected with my phone before.
Thanks for helping me ^___^

No worries, but you'll have to post a better screenshot than that, can hardly see it.
Sorry about that, this is my first time uploading a image on xda.

Yeah as you've not connected it before there is nothing there to remove, and seems like you've already tried everything. Not sure what to suggest, are you on a contract with insurance?
Nope, I got my phone in USA before it came out in NA. I had it imported via a dealer.

Atrix Wont Turn On

So I'm having a really strange problem, and it seems like the phone is completely dead. This may be unrelated, but about 5 or so days ago, my camera stopped working, and in the week before the failure, it would make a clicking noise whenever I used it. Last night however, I woke up to my phone rebooting itself over and over. I didn't know what the problem was, and didn't want to deal with it, so I pulled the battery out (not while it was booting). This morning, when I woke up I could not get the phone to turn back on. I tried two different batteries, tried each alone, and each plugged in to AC as well. No response from the power button at all, nothing on the screen, no green LED flash, nothing. Heres the odd part: If I take the battery out, and plug it in to my PC, the green LED turns on, yet, the power button still does nothing.

Phone going dead after a large Outlook e-mail synchronization

Hi guys,
I'm repasting what I wrote in my previous thread hoping you can have a clearer view of my issue.
My phone has the standard ROM, WP 6.5, nothing changed
I never flushed the phone, never formatted it, etc, everything is legit!
My TG01 has died many months ago and now I'm looking into ways of having it re-activated. I will explain to you my possible theories why it died, so maybe some of you will have an idea how to fix it
- For the first 4-5 months I only used PC USB (synchronization) charging, as I had a UK mains which obviously does not work in Europe. I noticed that the battery indicator was never really accurate, showing me the battery levels very vaguely.
- I often synchronized my Outlook e-mails with my mobile phone, one day my phone died when I chose to synchronize all e-mails. It died to an extent that the battery was completely empty. My PC wouldn't recognize it and it would only start for 5 seconds (the red led lamp would shine) and then die...
I somehow managed to revive it with my normal charger but afterwards it used to overheat quite a lot...
- One day I left it to synchronize again and the battery died on me again (at least that's what I think had happened)... the difference that USB PC charging did not work anymore as well mains charging. I was desperate enough to buy a replacement battery from eBay and I still have the same story. When I connect the phone to the charger I don't even see the diode lighting up anymore.. NOTHING. Any tips?
Could it be that the replacement battery is also so empty that even a mains can't charge it anymore? I heard someone mention something with cutting a wire etc, ... would that help me? IF so.. how do you exactly do that?
Thanks!
Hi guys,
So far no luck in getting updates from you, but I've got an update for myself:
I somehow managed to get the LED diode turn red when I connected it to the computer, which should be indicating the fact that the phone is charging, right? When I try to power it up the device manager recognizes a device called TOSHIBA DL... does this mean my phone is in some sort of emergency state?
The screen lights up a bit as well, but remains black.
yess this means your tg01 is NOT bricked. try take your battery out and put it back in so its totaly switched off then press n hold CAMERA, VOL UP, POWER keys to perform a master reset. if that doesnt work try this,
use the short pin method, put a .tsw in a PRG folder at the root off your sd card and short pins 1 and 3
if not,
download a tg01 rom in a .bin and flashh the .bin via tgdownloader
if you dont know these methods please tell me and i will link and help you.
Hi!
Thanks for your reply. If you could guide me a bit with the pins method, that would be great.
Also, when I plug in the mobile phone to charge now the red light is now flashing, instead of remaining constant, what could that indicate?
Phone never turns on now
hi there, it sounds like your battery has gone flat try leaving it on charge via USB for a few hours see if that will kickstart it and for the pin method
http://forum.xda-developers.com/showthread.php?t=654674
try to charge your battery first as it may just be a flat battery but if not you may need to reflash your rom via the pin method
if there are any problems or you are unsure message me back

[Q] Xperia X10i Bricked !

Device Xperia X10i, Unlocked Boot Loader, Rooted, Installed Jelly bean Rom of Feralab. Device worked perfectly on it. Since yesterday, after waking up, found my device bricked. Symptoms displayed after device got bricked :
a) If connected to wall charger with battery present, device only displays green light for 15 to 20 seconds max and then green light goes off. Then no activity in the whole device.
b) If connected to wall charger with battery absent, device again shows green light (with battery absent that is).
c) Tried SEUS, Answer : After the complete successful operation : Nada Nothing !
d) Tried Flash Tool, Still Nada. Tried flashing Xperia Stock Rom : Replaced System.sin , Header.sin and what not etc. "Even checked No Final Matchup" while flashing. Answer : Nada. !
e) Stock Used is "X10i_3.0.1.G.0.75_CUST-IN_GENERIC_1237-0692.ftf" flashed it. Still Nada ! However, no errors occurred while flashing.
f) Device when trying to switch on, displays green light blinked once, then vibrates and then just goes simply Naaadaa !!!
Nothing at all. Please help. If this helps, I am attaching log file of flashing device via flash tool. Man, device is just bricked. Answer and help appreciated . Thanks in advance.
Since I can't attach link to external log file on paste bin : here's I have uploaded the log file.
Update : Since I was on Fera Lab's Jb earlier, I want to notify that my "Unknown Sources and Debugging" was not checked in phone settings. It wasn't on and now that its bricked, I dunno whether it will make any difference or not ? In bricked state, with "Unknown Sources and Debugging" not checked. Can't get device to on, blinks one time green signal and then vibrates and nothing afterwards !
Update Number 2 : Hey, after completely keeping aside the battery for more than 24 hours, I connected the device to external wall DC supply (while battery was removed and never inserted after the 24 hours interval that is). After connecting the device to DC wall supply, it gave me the same response, flicked and showed green light and then vibrated and then nothing ! F1 anyone. !!!
Update Number 3 : http://talk.sonymobile.com/t5/Xperi...on-Flash-mode-even-when-plugin-to/td-p/273134
Just Googled my problem and came to this link. I can very much relate to the link although, His device was water locked, (there was this small white rectangle, if it is water damaged then it will be red) Surprisingly, his device which was water damaged shows the same symptom as mine. So, i checked mine, but the sticker or white rectangle for moist / humidity checker is white totally. So I guess it can't be water damaged, although, it showed the same symptoms !
Update Number 4: Since green Light was always On, I thought what if its in flash mode and much to my surprise, the device is in Flash Mode when I switch it on, how I found out : While flashing via SEUS, I didnt press the back key and the device got connected in flash mode by default, So i narrowed down the problem to something that : My device boots to Flash mode and not as it normally should ? Is it a mother board problem ? Can it be cured ? (god no please not mother board problem) So ? Any thoughts anyone to make it come out f the flash mode. ?
C] Tried SEUS, Answer : After the complete successful operation : Nada Nothing !
after the Successful Operation did you unplug the phone and tried to turn it on?
After the Successful SE Update Services was successful my phone didn't start, then i removed battery and reconnected, power on and works fine.
search in forums for Dr Goodvibes his suggestions did help me.

Your phone indicates an unlocked bootloader, just for your information.
What's the thoughts on the battery? Was it in a good service state?
Take the battery out of the phone for 48 hours and then put it back in the phone and power the phone on.
The green light for a few seconds indicates the phone is attempting, or in a recovery state.
Your phone may have just had a 'moment' and has a "locked instruction", that just needs to be cleared with no power applied to the chipset.
This has worked for others and is more voodoo than science, but worth a try.

Oh thanks for the update about the boot loader state. i definitely be keeping it apart for 48 hours and will update you regarding the same. thanks for the reply, you know i love this set of mine and your precious replies gives me hope.
Regarding the battery state, i guess it was okay, gave me a 1 day backup on the phone. So i guess it was in a kinda okay service state. though am not sure whether its fully charged or not. i don't actually know the power state / current charge level of the battery though coz i found the device bricked. if there's anything you can suggest, will be really helpful. though thanks for the information.
So I waited and waited for some more time, couldn't wait any longer for the 48 hours duration. Does t has to be 2 days ? I just wanted to bring my device back to life. Though, after giving up shortly after 12 + hours, I flashed it again, it did successfully, although, nothing even now, green light followed by a vibration and then boom. nothing ! f1 help needed ? btw, does it has to be 2 days?
I would have placed the battery back in the phone and pressed the power button and see if it booted, or allowed you to get to CWM Recovery with blue light or xRecovery(if installed).
One day, one week. How long does residual power remain in a circuit board to hold the current date/time before resetting?
Maybe buy a cheap BST-41 1500mAh battery for the XPERIA X10 and try that. Could be just a bad battery.
You could check the battery with a multimeter and see if it still has a charge.
My knowledge base stops at this point as I have no experience beyond this.
Good luck.

Thanks Dr. Goodvibes, I definitely will keep you posted. Though, when I plugged the battery in, first I did check, nuthing ! green light + vibration. and then it goes blank. I installed my feralab jb rom via xRecovery so, yes it is there (installed) but afterwards I have flashed the stock via SEUS so i guess even xRecovery is gone now. I am not for sure. Though it was installed earlier. Right now I am thinking of keeping it apart till the time i found a new battery, it can be even 2 + days. Even 1 week. I will wait for a week now. Thanks for letting me know all about this. Keep me posted.

Update Number 4: Since green Light was always On, I thought what if its in flash mode and much to my surprise, the device is in Flash Mode when I switch it on, how I found out : While flashing via SEUS, I didnt press the back key and the device got connected in flash mode by default, So i narrowed down the problem to something that : My device boots to Flash mode and not as it normally should ? Is it a mother board problem ? Can it be cured ? (god no please not mother board problem) So ? Any thoughts anyone to make it come out f the flash mode. ?
