Phone stuck at SONY logo - Xperia Z2 Q&A, Help & Troubleshooting

Hi there, I have a problem. I flashed a ROM and i guess it also flashed a kernel, while im on a locked bootloader... uh oh. The phone can still charge the battery and I get to the SONY logo but nothing after that.
I have tried plugging in a USB cable with VOL - but then windows tells me it cannot recognize the device. I have installed the flashtool drivers and PC companion drivers but no go. Any help would be appreciated.

Here is a recovery guide

I have tried this method. My problem happens when connecting the device after setting up flashtool. Windows tells me the device could not be recognized (device descriptor request failed), the phone flashes a red led when i plug in the USB cable and then green for a split second right after. then blank nothing, and the error shows up on my desktop.

I have done all of these steps now and still have the same issue. The drivers installed with no problem when I enabled test signing, but the phone still will not recognize on my computer.

Im busy right now, try messaging a dev or posting somewhere.
(yay college. Teacher is wondering why im staring at the floor )

Bump. I have a dead phone here, I've tried another computer and I am still getting these errors. I might have to replace the mainboard

we need more info to understand what happened and possible fix... what rom where you using before flash? lb or ub? what rom and kernel did you try to install and how?

It's hard to remember, my phone was in for repair for an entire month, but because of one chip on the back plate they deemed the issue a physical problem and didn't cover it under warranty.
I think I was trying to flash back to eXistenz but I believe I flashed a kernel by accident, slip of the hand I guess. I went to restart the phone and it became frozen on the SONY logo. The phone is LB. I just need a fix!

i think Envious_Data is right, flashing a stock .ftf with flashtool should fix your problems as flashing wrong kernel shouldn't hard-brick your phone, only soft-brick.
But since you can't get your phone properly recognized on the pc you either have a bricked motherboard (i don't think that's the case) or you are having driver issues on the pc (most likely). maybe try flashing on windows xp?

I agree with the above

Flashtool Taking Forever to Flash?? Help

My Xperia X10 is currently not working (see previous thread http://forum.xda-developers.com/showthread.php?t=993785) and I still haven't been able to fix it.
I'm trying to use Flashtool to flash the generic X10 Firmware to my phone although
it's taking up to 4+ hours and then my phone battery dies and the flash is unsuccessful.
Why is Flashtool taking so long to flash a firmware to my X10? I've tried a few different computers and still the same problem.
Please Help. Thank you.

I cannot access my phone as of now, it's pretty much a brick. Holding the on button brings only a vibrate and thats it.
what about flashing a rom that you know worked on your phone, making sure you flash the right Baseband for that particular rom first.
EDIT: Sorry just read through you posts and you have probably tried this if you have flashed a rom to it!

Is it possible to turn USB Debugging on without accessing the device??
not assuming you're silly. but you are making sure you have your finger firmly on the back button when you plug in the phone when flashing yeah? the simplest are often the ones that get you.

Read previous thread in original post.
The phone has crashed for some reason whilst using the FreeX10 Beta4 Rom and I cannot access the phone. It charges fine although I cannot turn on/access my phone.
not sure why the flash is taking so long. attempt to flash a different firmware possibly? Also do you have the latest flashtool?
Impossible to brick so you're not out of luck yet. Try flashing with latest flashtool 2.9.1
I'll attempt now with the Flashtool 2.9.1 beta. It's a shame that as soon as they unlock the bootloader my X10 decides to stop working.
EDIT:
'turn on Unknown Sources and Debugging' - It's impossible to access my phone to turn on USB debugging and unknown sources. What do I do now?
bump, anyone??
Attempt repairing your phone via Sony Ericsson Update Service. If that fails put a compatible basebrand and firmware on your phone. Make sure user data is wiped

Sony Ericsson Update Service does not recognise the product.
Not that I haven't attempted this but I put a compatible baseband and firmware and it took 7 hours in which it only flashed 4 items and then the rest flashed instantly which the phone displays blinking red light.
It's not working. Whats wrong???

Try to use SEUS to repair phone if you can't boot your phone. Do not use PC Companion cause' it will try to detect your phone everytime you use it but your phone can't boot so PC Companion now useless. If you can't repair your phone, you have to bring it to SE service.

It will not detect your phone dude. You must select your phone from the list supported. It will tell you to plug your phone in while holding BACK key and after searching for update, you will have a notice about update or repairing.

x10i wont start up

Hey guys,
I have an x10i that just went dead one day, I thought it needed a software re-install so I did it. Now it wont turn on and I just get a quick green blink and a vibrate when I turn it on. Ive flashed it 10 times via sony update too and pc companion and flash tools. I dont know what to do, any help would me much appreciated.
Download SEUS from Sony and flash. Make sure it is fully charged and make sure you are using the right USB cable and try using several different USB ports on your computer if the first one doesn't work.

Thanks for the response, I have a fully charged battery and just re-flashed with still no luck. What did you mean about the "right usb cord" ?
Thanks again.
I mean reflashed with SEUS (not PC Companion) and by right USB cord, I mean the one that came with the phone. Or if you have the possibility, try another one.
Tried with 2 different usb cords and on 2 different cpus. I think Im S.O.L
One more question, after a flash how long does it take for the xperia to boot up?
During a flash with SEUS it tells you when the phone is rebooting....same with the Flashtool.
Screen turns on...still black...then Sony logo, then your bootlogo followed by desktop.
http://www.youtube.com/watch?v=HmX-IYNYqL8
Is it successfully flashing using SEUS or flashtool? Does it actually flash and then not boot? What does it say when you flahs using the flashtool?
But again, if the flashtool isn't working, you are going to have to use SEUS to get back to scratch. Run it as Admin...let it boot up and do nothing to the phone for at least 2 minutes. Do not swipe or move a thing....let it settle down.
Some of you people who ask for help really don't provide much information at all.
To me it looks like a wrong firmware problem... version you have installed isn't the same as kernel.
I would flashtool....root....turn off phone....SEUS full reflash....

When the flash finishes up it says to turn on the device and the start up may take some time, Ive let it sit for hours and still nothing. IDK what the hell is wrong with it.
K well I give up. Ive tried 3 more times using a cpu with xp and still the same thing.
If any one else has had this problem please let me know.
looks like the faulty motherboard issue to me, some users are experiencing this problem, if you have warranty get a new phone if don't then i don't know what else can you do :/
Great. I have no warenty so looks like I'm screwed.

[Q] Stuck on Bootloop

Hello all.
My Xperia X10 Mini Pro is stuck on bootloop as you can see on this video
http://youtu.be/EhaBn0uuSvE
It just got like that from one moment to the other..I was using stock ROM
I tried to flash with Flashtool with these ROMs
U20a_2.1udpt1_Generic
ST17i-Active_4.1.B.0.431-1254-6360_SONY
On the first ROM it gets 100% successfull but still cant boot !
This phone was bought on Portugal, so I dont know if the ROM makes any difference..
Need some advice please !
I've read somewhere that Gordon's Gate (part of Flashtool) can still access a phone even when it bootloops.
Could you document what steps you already took? Perhaps link to the article you followed? (Below is a list of certain steps one usually takes when installing custom ROMS, but they are by no means always necessary, could you perhaps indicate what you already did?)
Rooted Yes/No/Not Sure
ClockWorkMod installed Yes/No/Not Sure
Unlocked bootloader Yes/No/Not Sure
Custom kernel Yes/No/Not Sure
The location of where the phone was bought will not make a lot of difference for the ROM. It might affect things like hardware keyboard layouts, but there are fixes available for those. But things like specific baseband and firmware are still important. By carefully reading the description, you can usually check if your phone can be used.
To be honest, I only have used Flashtool to flash new kernels to my X10 Mini Pro, for just installing another ROM I use ClockWorkMod.
What you can try:
Unbrick through SEUS: here (video)
I've read about people unbricking their devices with PC Companion, here.
If you should be able to regain access to the phone and still want to tinker:
This ROM works nice with the stock kernel
Later, you could unlock the bootloader, flash custom kernels (nAa ICS 04) and install ROMS needing such custom kernels (the U20 ICS ROMS, like MiniCM9)
Should you feel the need to ever unlock the bootloader, use this tool
Cheers and thanks for your post !
I used SEUS and updated to latest firmware but still no success on booting. It stills the same...
Rooted No
ClockWorkMod installed No
Unlocked bootloader No
Custom kernel Not Sure
Any chance that you can point me a stock rom and stock kernel to see if it boots that way?

Don't update, repair... leave your phone unplugged when SEUS searches for updates, it can't recognise your phone when it's not connected and will give you a repair option. choose that, and make sure you select your phone from the list presented. it will then flash original kernel and firmware to your phone.
Don't know which kernel you flashed before you got this bootloop, but the second rom you mentioned in your opening post isn't even for your phone, so i guess you got confused with what goes for your phone. You don't even get a kernel logo, so i guess you flashed a kernel for a different model altogether, or your stock kernel got corrupted. a repair should fix it.
I'm now updating on PC Companion like belgianguy said
If unsuccessfull I'll follow your instructions, thanks a lot in advance !
Same on PC Companion..no boot !
SmG67, I dont see any repair option on SEUS. It detects the phone and says thar it's updated. If I remove the battery while is searching my phone it keeps saying that it's updated. What am I doing wrong ?
On PC Companion I got the Repair option, it repaired, but...surprise...still can't boot !

That's a shame... because you now have all official sony ericsson firmware on your phone, kernel and rom... If it's still not booting the kernel, there's nothing you can do about it, maybe a repair-shop might be able to fix it.
Well, a repair-shop isnt able to fix it because the mini-usb port has bad contact and they consider this phone out of warranty because of that ! It almost never happens that bad contact..

Well if it's that far gone it might very well be a hardware issue. But just to be sure, could you start Flashtool and see if it still recognizes the device (see screenshot of what I see).
If it isn't able to, an older version of s1tool had an IDENTIFY option that required you plug the USB cable into the computer (but not in the phone), to shut down the phone, then push the BACK button and then plug the usb cable into the phone.
The bad contact you mentioned might be causing troubke as well, are you sure it isn't the cable that is at fault? Perhaps try to attach the USB cable in such a way that its not stressed and so that the phone cannot move (to prevent it from disconnecting due to a bad contact). Your flashes very well might have gone faulty because of that. But then again, the SEUS/PC Companion flashes seem to have succeeded, so hopefully Flashtool can shed some light here.

No connections

Murphy's law is with me tonight. Tomorrow, I'm meeting someone who wants to buy my xperia P so tonight I plugged out my sim-card, deleted my stuff on the sd-card and did a factory reset. When I rebooted the device to check if indeed everything was deleted, my pc didn't recognise the device. I tried on an other pc but no reaction. I hear the connecting sound and get a notification on the pc that says "usb device not recognised". I tried installing the drivers via SUS but that didn't change anything. I then tried if my sim-card worked but the device gives a notification: the simcard could not be recognised. My simcard is working correctly as it works in an other cellphone. I then thought I could install titanium backup to search for an old backup but I can't even get the wifi going. I also installed other roms but I can't mount /system. The device I have is rooted and unlocked.
Could you help me solve this issue?
Can't understand the problem exactly, is the device booting? If it is what does it mean you cannot mount system?
You also say you have installed other roms, that require mounting of system.
What FW is installed?

The device was booting but now it's stuck on the Sony image (before the loading image)
The problem is: the device doesn't recognise any simcard. I can't turn on wifi nor does the pc recognise my phone.
When in CWM (when I try installing a new rom that was already on the phone's sd-card beforehand) I can't mount /system.
I can pick a ftf from my sd-card to install a rom but afterwards the problems stay the same: no sim, no wifi, no usb connection possible.

After a lot of cursing and sweating I managed to get it in fastboot, install an ics ftf and now it's updating via pc companion (wifi and pc connection work as before). The only problem that still exists now is the fact that the device doesn't recognise my sim-card. I checked if I didn't put it in the other way around but it's in the right position. I'm sure the sim works because I tested it in another cellphone.
Thanks a lot for helping me
I have never flashed FW with fastboot only kernels.
Maybe it have flashed, TA partition which is normaly not flashed?
Lets see after the update.

I'm sorry it was in FlashMode The update gives me an error but somehow after I rebooted, the sim is now recognised :s
The only problem now is that I'm stuck in JB but I'm doubting to try anything else.
This cellphone has been nothing but random misery to me for the past 6 months The problem with the randomness is that I can't show it to the service centers (they keep on telling me they can't reproduce the problem).

Phone won't charge and isn't recognized by PC

Hello,
i just updated my z5c to android nougat(using flashtool).
A bit later it did'nt charge any more. I tried to reflash the ftf file,
but the flashing process stopped in the first 2 seconds. Now the phone
isn't recognized by the PC any more(in device manager I can see it, but the PC
does'nt recognize it as z5c. Device manager shows me error 10).
Bootloader is locked, do you think there is any way to fix it by myself?
Or should I send it to Sony? Problem is the backside is broken(happened a month earlier), so most
likely they'll say I have to pay it.

can it bootup completely and work properly?
wipe through recovery and try to reflash can be helpful
however if you are not comfortable with it take to official service center
