Hi xda,
After changing my phone's system language to French (from English) for a school project, I eventually rebooted my phone and now it is stuck in a boot loop. It keeps getting to a point about 5 seconds in to the blue wave animation, then freezes, and reboots again. I have tried booting it into the USB safe mode (hold Volume Up while plugging it into a computer) and I have tried to boot into recovery using ADB, it says it cannot find the device.
I believe it is running Android 4.4.1, although I cannot check this.
Any help would be greatly appreciated.
Thanks in advance.
Install adb drivers and download flashtool
From Flashtools folder find drivers folder and run exe
Check fastboot and flashmode and xperia z3 compact drlvers. Install and turn off your phone, find your ftf file select it when it asks to connect your phone hold volume down button and insert usb cable and good luck

The problem.
When I boot the device it just stays at the Sony screen and does not progress any further. I am still able to turn off the device by holding the power button and the volume up button, I can reset it by holding the button longer waiting for the vibration, and I can hard reset by waiting till the three vibrations.
What I was doing up to the point it happened.
I was trying to get a custom ROM on my device, I had it previously rooted so I thought I would go further. I installed CWM on my phone I wiped data, cache, and dalvick then I went to install the ROM from SD card. During the attempt at installation I got some symlink errors with a status of 7. Not sure what to do turned off the device when I decided to put back its previous I turned it back on and arrived at the problem.
What I have done to try and fix it.
I have done the soft and hard resets, I tried using the PC companions repair tool. When it asks me to turn the device off hold down the power button then plug in the device nothing happens(I have tried this several times.) I downloaded the flashtool and the correct ftf and tried using that, but it doesn't detect my device when I hold down the volume button and plug it in. So it seems that the flashboot is not working on my phone.
Any suggestions on what to try would be much appreciated and thanks in advanced.

You probably didn't install the ADB drivers. Install them from the Flashtool folder (use the ones for TX) and then try flashing your stock FTF again. Remember to put the device into Flashmode.
Basically what happened was that while flashing your ROM the script that flashes everything deletes everything from the /system partition, then you got an error and the installation was incomplete, therefore there is no proper system to boot into. You could have easily avoided what happened by flashing a different ROM had you not powered off.

Thank you for response, I went and used the Flashtool-driver.exe and installed the Flashmode drivers, Fastboot drivers and the TX drivers. But it does not seem to have changed anything. To enter flash mode on the phone one has to hold down the volume down button while plugging the phone into the usb when it is powered off, right? Flash tool just sits at the instruction animation titled Wait for Flashmode. When I try to enter flashmode I do not get a response from either the program or the phone. Any more suggestions would be welcomed.
Thank you for taking the time to help.

Yes, that is how you enter flashmode. Turn off phone, and keep volume down button pressed while you connect the USB cable; the LED light should turn on with a green light. If you're phone is not entering Flashmode, then you might have a faulty USB cable, or there might be problems with your USB ports, either on your computer or your phone (try with different cables/computers).
Also, check your Device Manager (while phone is connected) to make sure the drivers are properly installed. If you have Windows 8, you should have had to turn of Driver Signature Checking in order for the drivers to install properly.

Yeah I turned off the Driver signature checking on my computer when I did it. I'll go buy a new cable and try a friends windows 7 computer. Hopefully there is nothing wrong with the USB port in my phone. Thank you for your help I'll let you know how it goes.
Thank you everybody for your support. My phone is now working. After my phones battery died I was able to get it charging, when it had enough energy it booted itself to the Sony screen so I turned it off and grabbed my new micro USB cable and was able to get it into flash mode. Everything is now working great. I wish a special thanks to Antiga Prime for taking the time to help me.
Please excuse me if I'm repeating a prior question but it seems far too specific to trawl through pages of related threads to make sure.
I decided I was going to sit down and root my Xperia Z1....
Steps:
1. I installed ADB and Fastboot via the latest windows Android SDK (r23-.0.2), in fact I had to source a sony version of the fastboot driver in order to get it working but once I'd done that all went ahead as planned.
2. Generally followed this guide (wont let me post a link but google "honami cyanogenmod" and it's the 2nd result)
3. All was going swimmingly, I entered fastboot mode absolutely fine, flashed CWM using fastboot which all loaded up absolutely fine.
3. At this stage ADB was not picking up my device at all, tried different cables, ports, all of the usual. What I didn't do was make a backup, and then I wiped all of the things that it's possible to wipe thinking to myself that I was going to get Cyanogenmod on there so all would be fine...
4. Finally I (quite stupidly) restored from memory card (which had already been wiped) from inside CWM, the device restarted and now I am getting no response AT ALL.
5. Sometimes it will load the Sony 'splash' logo that first appears but sometimes not, when plugged in the device is recognised and ADB actually sees the device but lists it as offline... Interestingly at this stage windows device installer actually installs Sony ADB driver for me automatically.
6. All I'm getting at the moment is a red flashing LED although when I plug in via USB the device is again recognised when I type adb devices but again is offline...
If any more information is needed please, I will be more than happy to give a quick reply.
Thank you in advance

Were you trying to root your phone or install cyanogenmod? You followed a guide to install cyanogenmod on xperia Z1.

I was trying to end up with a rooted device running Cyanogenmod, I've been putting it off and off looking into the whole rooting scene and mistakenly dived in a little too quick without knowing what I was doing.
after that you move cm-11-20141112-SNAPSHOT-M12-honami.zip to your sd card. Now you have flashed boot.img you can't move zip to your sd card using z1 you had to do that before using fastboot. use some sd card adapter and do it. then put the sd card back in your phone. turn it on then enter the cwm recovery pressing Vol+ for a few seconds when the sony logo shows up. select full wipe data. then install from zip. choose cm-11-20141112-SNAPSHOT-M12-honami.zip. reboot. ADB won't work until you have installed cyanogenmod zip. You have only installed cyanogenmod kernel and custom recovery when you flashed the boot.img.

Firstly AkiraProject thank you for your time on this.
I do realise that in my stupidity I could have loaded the cm-11-20141112-SNAPSHOT-M12-honami.zip to my SD card (if I'd had one or waited and gotten one).
What I did however was wipe everything I possibly could, and then hit restore from sdcard/0/ I believe - it may have been a different directory.
I believe what I have done is restored to a blank image......
WHen not plugged into usb I get a red blinking LED when just pressing the power button once.
When holding volume-up + Power the phone vibrates as if it is trying to boot but is unable to
If I leave it plugged into USB AND then press , the device shows the sony Logo and then proceeds to display a backlit but plain black screen, Sony PC Companion recognises the device as connected but is unable to interact with it. The output of "adb devices" shows my device but says "unauthorized" and windows is attempting to install MTB driver....
The behaviour doesnt seem to be quite the same every time.
I believe the device is soft bricked.... is this likely to be a case of a wiped partition table? Or at least loss of the boot partition?
If I leave the device plugged in via USB it periodically reboots itself, shows the Sony logo, remains on a bank screen then shuts itself down.
Shows in device manager as "USB Input Device" on win 7 x64 pro
Thanks in advance
Pretty certain it's not hard bricked, there will be instructions here you can follow:

I have done quite a lot of reading etc on the subject....
according to This thread, Sony Xperias have the bootloader in non-writable mask ROM... so you should always be able to access Fastboot or Flash Mode?
The problem I am having is that I don't seem to be able to activate EITHER Fastboot OR Flash mode in order to flash some new firmware onto my device....
My device is recognized as a "USB Input Device" on Device Manager and windows tries to install MTP driver. I'm going to have a go at the process with a fresh install of windows 7 x64 and 'windows auto-install drivers' turned off.
What is the maximum damage I could have done here?
Thanks
Update
Hard reset (red button inside of the sim-card slot) resets the phone with three vibrates and it restarts.
The phone powers on and displays Sony splash screen and then displays a back-lit black screen.
The phone gets much hotter than normal and powers on to the blank back-lit screen when on charge.
I have NO ACCESS to flash mode or fast boot. Any combination of buttons leads to the same outcome: single vibrate, red LED and the phone shows the Sony splash screen then blank screen, as if the button combinations are just ignored...
Flashtool DOES NOT recognize the device, although it is recognized as C6903 in device manager (I have Sony adb driver installed and have disabled the MTP driver that windows recommends).
Flashtool gives me the red error text about making sure drivers are installed and making sure the device isn't in MTP mode.
I'm at an absolute loss as to what to try next, can somebody shed any light on this? There are plenty of guides but they all seem to rely on EITHER fastboot or flash mode and I can access neither although the phone powers on!
Thanks in advance!
Maybe the partition was corrupted when you flash "blank" image..........
So....JTAG....or send to Sony service....
Shutdown with power+vol up (will vibrate thrice) and see if it doesn't turn on automatically.
If it didn't turn on now check your task manager on windows, go to process tab, kill adb.exe (every adb.exe)
Back on phone connect usb holding down the vol down button (phone have to be off before you connect usb), if green led turns on and doesn't turn off you are on flashmode.
Check on flashtool or flashtool64 (for 64bits) and see if flashtool detects your device. If it detects and recognizes your phone flash the FTF for your device and let it do its job.
As you messed the phone Sony will charge for repairs.
Lately my phone cant go into boot, it just show sony logo, then the logo blured, and it back to sony logo.
I had just done install cwm with this method

It happened to me too, the only way is to flash a stock based rom through flashtool, then flash cm11 and then cm12. I suggest you to flash CrystalPA though and wait for a more stable cm12 release. CrystalPA is just the smoothest 4.4.4 rom out there, especially if you love mobile gaming, it has the best ram management!
Hi everyone! I have a xperia sp locked BL, recoveries installed. Last night I installed a rom and get bootloop. The phone automatically reboots but I can't see flashlight to get into recoveries and stucks at Sony logo. I pressed the OFF button at the back, the phone reboots and stucks at sony logo again. i cant connect it to flastool also. please help me what to do next
I read something on google but i forgot how to do it exactly :s Tried reinstall with pc companion? Though I don't know if that would work and I don't want to be responsible for bricking ur phone :/ So i guess google "Xperia SP bootloop" :s

Have you tried to connect to pc, and type adb reboot recovery (with adb installed on pc)?
Firstly download and install minimal adb
Download doomlord's adb drivers..
Then if on windows 8
Disable driver signature enforcement and then install the adb drivers in doomlord's thread.
(Fast boot drivers, flashmode drivers and viskan drivers)
Then extract boot.img of your favourite ROM (which has a recovery) and copy paste it in the folder where you installed minimal adb.
First connect the USB cable to the PC.
Restart your phone by hard reset and as soon as it shows Sony logo, keep pressing power button plus volume down.
Now a blue light will be coming.
Then
Hold shift and right click there and open command promt here..
Make sure the blue light is still there in the illumination bar and type in
fastboot flash boot boot.img
This will install a new boot.img which has a recovery
And then restart
Then go into recovery and flash your favourite ROM...
Hope I helped..
This method worked for me many times...
Hello everybody, :cyclops:__ sorry for my bad English __ :cyclops:
I have a big problem in my huawei p9 after soft update, i leave it for a night to complete the process of download, is updated but stay reboot again and again, i tired to install another firmware but nothing happened :crying: :crying: , so i googled for howa to install firmware via pc, i found by adb fastboot, and i flashed, but (Developer options, Screen lock & password, Camera, torch ...) Not working, i downloaded many firmware nothing works fine, i don't have a Box to repair this big problem.
Any help please please, any tool to update from pc

Been there before, but recovering it is rather easy, first of all you have to install TWRP, you can do this by connecting the USB to your phone and PC and holding volume down to get to the white download mode screen, next use ADB, put the TWRP image in the ADB folder and type this: "fastboot flash recovery <twrp image name>.img" (without the "") from there remove the USB cable and reboot holding power and volume up until the Huawei logo appears, boot into TWRP and connect the USB cable back again. On your PC download a firmware for the phone and use Huawei Update Extractor to unzip it, find UPDATE.APP and keep it on the desktop. With your phone connected to your PC make a folder on the phone named "dload" and copy the UPDATE.APP file into it.
Shut the phone down and disconnect the USB cable, next hold volume up, down and power (yes, all three) and the phone should automatically force install the firmware and it should be fine from then on.
Hope this helps.

Nop a tried all of the solution, i flashed recovery,system,boot (.img) through adb fast boot, nothing works fine, after turning up the phone ( Bluetooth not working, camera not found, security& password not woking, i cant access to Developer options)...., I think i flashed a bad firmware
just signed up to try to fix this problem myself, never used a forum before haha but i was a idiot.
im hoping that im just being an idiot and putting the wrong update in the dload folder, but ive also tried to do all of the steps above. then tried to upload a custom rom but none of them seem to want to work either. been trying to fix this for the last 2 days with no luck.
