[Help] Stuck in a boot loop, computer won't recognize phone - Xperia Z3 Q&A, Help & Troubleshooting

I have a d6603 Z3 on 5.1.1. I attempted to use flashtool to downgrade my firmware as per this thread: http://forum.xda-developers.com/z3/general/guide-rootrecovery-how-to-root-install-t3017056
After allowing it to flash, the last lines were:
10/058/2015 23:58:25 - INFO - Please unplug and start your phone
10/058/2015 23:58:25 - INFO - For flashtool, Unknown Sources and Debugging must be checked in phone settings
Once I did that, the phone would start and during the boot process it would freeze and restart. Connecting to my computer shows that the battery is at 50% no matter how long it's connected. I've tried holding the power button with volume up, or power with volume down, and doing those two while connecting to computer, and nothing. Pressing the yellow button and getting the vibrations don't help. Trying to use PC Companion Repair, but that's not getting anywhere because when I hold the volume button while connecting the device, it doesn't recognize the device. Sometimes the phone will vibrate once while holding volume down when I do that. Still nothing. I'm at my wits end here.

looks like software brick. If you havent unlocked the bootloader go to service center and get it done. but you will get latest 5.1.1.
dont tell them you used flashtool n all.

Hmm, I'll have to wait til support lines open up. I'll report back sometime in the morning/afternoon.

I've just contacted Sony. They want me to send the device in for repair. I didn't tell them what I was attempting to do, only that I was in a boot loop.

I was in the same case and resolved it that way :
Note : locked bootloader
* installed flashtool on my computer (debian 8) : http://www.flashtool.net
* downloaded stock firmware for my isp (orange, france) : http://forum.xda-developers.com/z3/general/ftf-stock-firmwares-xperia-z3-models-t2886061
* followed http://forum.xda-developers.com/showpost.php?p=45187952&postcount=2 to flash the ftf using flashtool
* got my phone erased and back to stock KK but no more boot loop, and no sending to sony for repair.
Hope this helps and will work for you.

If you use pc companion try going into fix phone and manually select the phone model your fixing and it should force a flash through. Your just going to have to charge it up a bit if possible.
Worked for my boot looping D6616 which I had never hooked up to pc companion before.
Best of luck

Phone will not boot past recovery. Please help, major panic!!

Oh dear.....I hope I haven't destroyed my O3D....
I was attempting to install the V10D update, so used the backup I took right after rooting and installing ROM Manager to restore the phone to its status before installing the performance pack. If I tried installing the update OTA before this I just got an invalid package error.
So the restore went well and it rebooted fine. So I ran the update again, and it downloaded and appeared to install, but when the phone rebooted it just booted straight into the recovery. I tried to get it to reboot again, but again it just booted back into recovery.
Ok, nothing to worry about I thought, I just ran the restore again with the same restore point as before....but after it finished it's still booting back up into the recovery!!! No matter what I do the phone just seems to keep booting into the recovery menu. I've tried booting into emergency mode by powering the phone off, then holding the UP Volume key and holding power, but it doesn't seem to work.
Can anyone help? Please?
Lil update -
When powering off the phone and then connecting it to the USB cable, it automatically boots into recovery mode without me even touching the power button. At this point the LG Mobile Update detects the phone and advises me that there's an update available. I try to apply this, but after entering the SN and IMEI, it just gives me a message "Updating is not possible any longer due to a fatal error while the LG Mobile Phone Software Update". I get the same error if I use the recovery Phone option. This always happens at the download stage, so is it possible that it's just failing to download the update from LG rather than actually do anything with the phone?
Please don't tell me I've ruined my brand new phone!!
Unfortunatly, you've managed to do the same as I have... leave the phone for e a few days and wait for a rom that you can install via clockwork recovery, you'll have your phone up and running again. Dont do as I did and wipe the recovery from the phone, it will result in a total brick (or at least a brick till LG releaase a full rom update (could be months yet...).
Oh man, I'm panicking so much that I might have ruined the phone now.....

I'm not sure what I'm looking for there, I've looked through that thread but it doesn't seem relevant to the problem I'm having.
I have the same problem, if you put it into emergency mode you can update to 10d but then its even worse then you are stuck in the firmware update screen
tomorrow I leave on holiday and was planning for nice 3d pictures and movies but I am screwed...

Don't panic, I managed to totally brick my phone today and LG told me to send it back for DOA but I managed to recover it in the end.
My phone wouldn't show anything on the screen, it remained black so I can say your position sounds much better than mine.
What you will need:
USB Drivers - Download from here (Check note)
LG Mobile Support Tool (LGMST) - Download from here
Before you start: Disconnect the phone from the computer and totally remove the battery.
So here we go:
!!!REMOVE ALL THE LG USB DRIVERS FROM THE SYSTEM BEFORE YOU CONTINUE!!! Go to add remove programs, select the LG United entry and then uninstall it.
First install the USB Driver from the link above and wait until it has finished with the setup.
Then run the LGMST. When it starts and it says "Disconnected." then put the battery back to the phone and connect the phone to the computer.
Press ONLY the Power button and wait until something happens. If you see that the phones boots and the LGMST starts it by itself then wait till it stops with all the information gathering stuff.
Then regardless of what the program says of you having an update or not, DON'T START THAT UPDATE!
Click on alt on the keyboard and the from the menus at the top select Customer and then emergency(the last option).
Type in the phones IMEI (located at the box of the phone or on a sticker under the battery) without dashes, just numbers.
Finally click on Check and follow the instructions on the screen.
You should be ready as new after 10-15 minutes with the standard V10B firmware and you should not even lose data.
Tell me if that helped so if it didn't we can still fix it I'm sure
Note: I'm aware that 3.3.0 is the latest USB driver that it ships with the phone but for some reason I had only success to flash the phone using the older 3.2.1
That does not work for our problem, just a blank screen is better than stuck in firmware update mode :s

I'm afraid that didn't work (I think I'm gonna cry soon)
When I go to the Customer Support option, the last option isn't called Emergency it's called "Recovery Phone" and seems to launch exactly the same thing as it does if I click the big "Start Updating" button. There is no option named Emergency at all. Does that mean my phone isn't/wont/can't boot into Emergency mode?
I don't even hold down the power button for my phone to switch on, the second I insert the battery it boots into Clockwork Recovery. If I power off the phone and connect the USB, I don't get the battery charging animation or anything, the screen just remains completely blank. Then if I press the power button (alone or with anything else) it just boots to Clockwork recovery.
The LG Mobile Support Tool seems to detect the phone in this state, but as I said, when it tries to do the download, I just get an error saying "Updating is not possible any longer due to a fatal error while the LG Mobile Phone Software Update". The version of the Mobile Support Tool that it's installing is 1.5.1.8 after downloading from your provided link, just incase you need to know that. It seems the tool automatically updates itself on every launch.
Someone also seems to have posted the actual ROM in this thread, http://forum.xda-developers.com/showthread.php?t=1155874 would installing this perhaps assist? Is it even possible to install this when my phone wont boot up past the recovery manager? If it is possible can someone perhaps advise me how?

Unfortunately the phone wont boot into Emergency mode. The clockwork Recovery mod seems to have taken over all of the boot options. If I hold the volume up key and press the power button, nothing happens. If I hold the volume down key and the power button, it boots to clockwork recovery. If I just press power, boots to clockwork recovery.
Is there any way to strip off Clockwork recovery and restore the original/stock recovery onto the phone? Or even just remove Clockwork recovery so that it just hangs on the LG boot screen? (See reasoning for this below)
I can still select the USB mount option in Clockwork recovery and the PC still picks it up as a storage device and I can browse around.
The phone is only 7 days old, so I'm almost tempted to just delete the internal memory so that clockwork doesn't show up, then take the phone back to the store and say it wont boot up and try to get it replaced.
Or what would happen if I renamed the clockworkmod folder on the phone's hard drive?
(Just another note, I don't have an external SD card in the phone, just the internal memory)

How else can I put it into Recovery Mode? How can I tell if I've done it right?
I managed to hold the up volume key and hold down the power button, and the LG Mobile Update detected the phone whilst the screen was blank. I thought that meant I was in recovery mode?
I should point out that the LG Logo wasn't flashing up however. I only ever see the LG Logo before it boots into Clockwork RecoveryMod
I also got that fatal error thing when i bricked my phone. For me the phone would start flashing but it got stuck at 17% and then an error followed saying that there was a communication problem between the phone and the pc. My solution was to switch from my desktop computer to my laptop and the procedure ran smoothly after.
You said that the phone powers up directly after you connect it to the pc and while having the support tool running?
You can try to shut it down so it shows a black screen as you said and then try to boot into emergency mode with the vol.up+power button.
The windows sounds might help you on that. you can listen from the computer when the phone connects/powers up or not.
EDIT: Just read your post, if the phone remains black is a good thing.
if your update fails or goes into clockwork recovery etc you will need LG mobile update on your pc and install the lg p920 drivers
turn your phone off take the battery out leave it for 10 sec, connect battery and usb cable hold power and volume up hold it for 10 sec let go then do it again for 10 sec
now run LG mobile update click customer support > recover type your imei let it update once finished power up phone now you will get a screen on the phone that says updating let it update
Well I'm not sure what I did differently. Not sure if I wasn't pressing the button hard enough or my finger was slipping off, or if I've just somehow tricked the phone, but the LG Phone Update from the Phone Recovery option is now running.
I've been doing the same thing I was doing before (or at least thought I was doing) and I'm not sure what I did differently....but....fingers crossed..... the download will finish in 40 minutes (on a crappy connection at the moment) so I'll be able to see what happens then....
UPDATE -
Progress, though not quite yet success.
The LG Mobile Support tool downloaded the software and applied the update succesfully, though my phone didn't automatically restart. I pressed the power button however and it loaded up and not into Clockwork Recovery Mod. It's not however sitting on an "Updating Firmware" screen and the progress bar doesn't seem to be filling at all.
How long does this part of the process normally take?
Does the phone need to be connected to USB for this part of the process? The LG Mobile Support Tool says the phone is disconnected so I'm guessing there's no active data connection between the PC and phone, just power.
Does this normally take a while? Or should I perhaps try the recovery again?

This is only supposed to happen when you apply the OTA update. Try to reapply the stock firmware in emergency mode. After the program applies the firmware, it should boot up the phone by itself in android and give you a success or finish message on the computer.

Is applying the Stock Firmware not what I did with the LG Mobile Support Tool when it downloaded that huge 300MB+ file?
I have contacted the customer services for Carphone Warehouse, and the guy advised that if the phone seemed to have developed a fault and wouldn't start, then since it's within 28 days of purcahse I can get a like for like replacement. Might have to go ahead and do that this evening.

[Q] Root a Bricked SE Xperia Active? (only USB working)

My phone has turned itself of without any clear reason, and will not turn back on. (Only green light flashing + little buzz) SE Helpdesk advised me to reïnstall te SE software, which did not give any erros. But the screen stayed black after rebooting. After being on the mains over night the phone seemed to work this morning, shortly, but now it is dead again.
Because of the phone not starting I cannot use any of the noob-proof toolkits. Nor could I find guides on handeling this without the phone being able to switch on. The only thing that is working is the USB connection, whilst holding down the volume - button.
Anybody with suggestions?
The good thing is that the service mode works. I think that you should be able to reflash firmware using Flashtool.
First of all, download the FlashTool from here:
http://androxyde.github.com/Flashtool/
After installing FlashTool, place .ftf firmware file (download link is below) in the firmwares folder in FlashTool installation directory. After that, run the FlashTool, and click the little button with the black lightning on it (first button from the left), then the dialog box will pop up. In the dialog box choose the flashmode option. Click ok. Then connect your phone to computer via USB. While plugging in your usb hold the down volume key. Flashing process should start. Wait a few minutes, and hopefully, you will have your SE Active Working again.
If you have any questions or problems, feel free to ask me.

Xperia Active (ST17i)
!4.0.2.A.0.42 - http://www.mediafire.com/?3zm7iss0sid94wr
---------------------------------------------------------
Flashing went ok, thanks for the help. Al least, the Flashtool did not give any errors. However the phone still won't boot, the screen does not come on.
Maybe it's a hardware problem, but I didn't drop it or something like that... And it should be an very robust phone
I suggest you to contact the manufacturer for the possible hardware error.
Use Odin or SuperOneClick

Miro bricked after flashing wrong bootloader

Hi,
I don't know what can I do now, perhaps noting. I accidentialy flashed wrong bootloader (from other xperia, not Miro). Now phone seems to be completly bricked, I can't turn it on and my PC does not see any new device after connecting phone to usb. I also tried to remove and insert battery, after this when trying to power on, there is short vibration and nothing more.
Do you have any ideas? Or I simply should to use it as brick, not as phone or put it to my toilet and wash? Thanks.
Can you get in flashmode? Power button down + connect to pc. Flash proper ftf for your phone.
Sent from Xperia M2 D2303
Don't worry, Your phone is not hard bricked. As you mentioned that on starting , phone is vibrating that means there are chances to recover your phone.
1.First go through this guide :Using Flashtool for Xperia devices
2.Download your current stock firmware . Visit this: Miro all official firmwares
3.Install proper drivers as mentioned in the above 1.flashtool guide.
4.Flash the firmware for your phone , according to the above 1. Flastool guide.
5.Wait untill flashing completes. start your device when you are told to do so.
Good luck :good:

You should see green light. Try this :
Pull out battery, hold power button for 10 seconds without battery. Reinstall battery, hold volume button - and connect to usb. Then follow steps that prateek.invasion gave you.
The point is you can flash ftf and restore your phone.
Good luck.

Thanks, I will try. Batteery is not charging, so I need to do this quick, it was not fully charged.
Unfortunatly, I can't do anything. I tried to connect while Volume down + power pressed. But nothing happens, only led flashing with red color. PC can't see any new device after I connect to usb.
Any ideas?

I had the same issue with my xperia e after I unlocked the bootloader and installed CWM, the phone just rebooted itself at boot up. If you have installed CWM I suggest you to install a custom rom and a new kernel. That worked for me . Or ofc, if you have warranty you can send it to them. They won't be able to tell if you installed another rom since the pc doesn't recognize the phone.
I don't have cwm... trying to connect to computer with volume down pressed. After this led starts flashing red and computer can't see any device connected
Seems there is no any recovery or I can't put it to recovery mode.

Xperia Z5 E6683 dual - Boot looping

Hi all,
i have been attempting to root my Z5 dual, i have unlocked the bootloader no issues.
but when i got to the stage of trying to flash TWRP.img thats where i ran into issues, it flashed ok - but now my phone won't boot - it is just stuck on the white sony screen.
the only way to turn it off is to hard reset ( hold power button and the volume buttons until it vibrates 3 times ) - then it will power on if i hold down the volume key and press the power button - or plug it into a wall charger..
when it does turn on it gets to the sony screen - the LED goes white, then amber for a second or two then the LED turns off..
im not too sure what to do now guys - my laptop wont pick up my device any more so it seems as though i have soft bricked it. i have also tried the P.c companion thing also but it says i have modded software so it can't do it lol.
help me pls
Hi,
If you already have installed the z5 drivers on you laptop (i assume this is the case because pc companion is installed and detect your phone), guess you can try to flash a stock Rom of your contry using flastool, your laptop will normally detect your z5 cause you connect it thanks to a special manipulation (vol - + connexion while button is maintained) .
Try this if everything goes great, it will fix the bootloop issue.
I got the same prob and eveb worse (battery 0% and wasnt charging) i hard rest it ( vol up+ power) and left it for 10 seconds then i pluged into my laptop while holding vol down and suprisly my laptop detected my phone and i was saved ! But i was scared about the flashig procsess as my battery was 0% lol

You dont need put your phone in fastboot mode than flashmode.
Sent from my Sony Xperia Z5
flashmode not fastboot mode . make sure u install flashtool drivers and fastboot drivers and ur devices drivers as well. dont skip this just cause u think u did it. if you are on a windows pc windows 8 - windows 10 , you have to disable signature verification in order to install the drivers. if you dont know about that , tell me to explain . apart from that , what commmand did you use to flash twrp? fastboot flash boot twrp.img or fastboot flash recovery twrp.img? if you did the first , thats why it doesnt boot. and apart from that , can you at least enter the recovery ?

Tried relocking bootloader and now cannot enter bootloader

Hi, I just flashed my stock rom (oos10) and it was working, but then I tried to relock the bootloader for banking apps to work without root.
As soon as I did, I got a message saying "Your device is corrupt. It can't be trusted and will not boot."
It shows this message as soon as I power on the device and no boot animation. When I tried holding down power+volume up and then immediately power+volume down to get to bootloader, it still showed the message and didn't do anything. Is there any way to get out of this loop?
Cheers!
Edit: My device is the original nord from india on indian firmware.
I had the same issue. Use the msn tool.
Follow these steps:
1. Turn off your device
2. Connect it to your pc
3.Hold down volume up+volume down+power (you should hear the windows new device connected sound). The screen will NOT turn on but MSN should detect the device now. (if it`s not detected make sure you follow the msn tool guide to have the right drivers)

If exclusive service center is nearby ..go and ask to flash sw..they will not take charges as it's free
