This xperia zl phone is not mine phone, I would like to revive the phone. I did try to update few different FTF firmwares using FlashTool and sony pc companion.All this tools looks like working ,only Flash tool at the end was giving me the warning that to be able to use flashTool require to unable option in settings that makes me wondering.
After updating the TFT firmware the phone reacts exactly same way as before updating a firmware :after pressing power no vibration only red light blinks 3 times.I'm able go access download mode and by pressing volume up I can access as well fastmode (blue solid light) .When the phone is plug to charger it will show xperia logo for 2sec and infinity bootloops .When I press reset button located inside close to card slots and plug the charger the pfone vibrates once , space 2 sec and vibrates 3 times .
I m wondering if its possible the battery could be bad or hardware or software issue.The phone was not modify just happen to be dead.
Any help, idea how to revive the phone very much appreciate.
I had this problem a few days ago just let it charge and bootloop eventually it will boot up and you will be able to flash stock firmware

Hmm... first of all... just to be on the safe side, please update Flashtool to the latest version (0.9.19.10) and try once more. Please report back once you tried and let me know if it still fails or that it actually worked fine that attempt.

I have the same problem...
I have installed the XZ-lockeddualrecovery2.8.26-release.combined from my PC...
everythig worked fine, I did a back-up on the SD card.
after that I copied on another sd card the cm-13.0-20160507-unofficial-uga.zip, the z.5.1.1 ramdisk replacer for cm13.0, open gapps arm 6.0 nano and the xz.zip...
I started again recovery from the PC, I think that was the mistake, and tried to install everything in one move...
I think there was not enough space on the ram for all this...
the phone bootes until the xperia logo and then freezes.
I tried a lot of thigs with no success.
thxs in advance for your help!

flash log afterwards:

This xperia zl phone is not mine phone, I would like to revive the phone. I did try to update few different FTF firmwares using FlashTool and sony pc companion.All this tools looks like working ,only Flash tool at the end was giving me the warning that to be able to use flashTool require to unable option in settings that makes me wondering.
After updating the TFT firmware the phone reacts exactly same way as before updating a firmware :after pressing power no vibration only red light blinks 3 times.I'm able go access download mode and by pressing volume up I can access as well fastmode (blue solid light) .When the phone is plug to charger it will show xperia logo for 2sec and infinity bootloops .When I press reset button located inside close to card slots and plug the charger the pfone vibrates once , space 2 sec and vibrates 3 times .
I m wondering if its possible the battery could be bad or hardware or software issue.The phone was not modify just happen to be dead.
Any help, idea how to revive the phone very much appreciate.
Just happened to me, after normal using RR latest build 5.8.2 on my Xperia Z, after a reboot, i only got xperia logo and then bootloop. I was able to access only fastboot. I thought battery died, although it was 50% charged at the time of reboot,because it looked like it couldn't charge. So i ordered a new one and in the meanwhile i opened the back cover just to be ready to replace the battery. Then i tried to disconnect the battery, put charger in and while charging reconnected the battery. Phone came back to life and now its charging (waiting to charge at least 50% before i try to boot, battery was completely drained), so maybe that's the case with you. Battery can die even though it looks like its not fully drained.

Bootstall

Hi, I'd never heard of a bootstall but that's what I had. Followed the instructions (I would never found a ROM that old) and it works perfectly again. Thank you all.

Flashmode

Problem with Xperia Z after a serious mistake i made. I had Android 5.1.1 and TWRP 3.0.2.0 recovery.
The wrong was that i flashed within Recovery newer TWRP version, 3.1.0.0 img file. It gave me only one option to be flashed into BOOT section, and i made the mistake to accept that, but i sould not proceed because did not gave me option to flash on FOTA .After that phone fall to Bootstall. The flash mode stop work, led blink red and green once. Fastboot mode works and i flash many Kernels. I try to flash many other versions of Android 5.1.1 but no one worked. I flash Android KitKat 4.4.2 and the phone worked with errors. I flash Resurrection Remix N v.5.8.3 and phone works perfectly! but the problem remain. Does any one know how can i make flash mode (Power key + Volume down) work again? Boot loader is unlocked. Thank you.

My phone starts with SONY logo (during 12 seconds), then turns to black (with back-light) and automatically reboots after 18 seconds.

fastboot mode is OK (POWER + VOL DOWN)
flashmode is OK (POWER + VOL UP)

Try to unlock (as I used to do it before) but :
- always ends with COMMAND FAILED ERROR with command line
- seems to be unlocked using flashtool BLU function but doesn't unlock it for real

I don't know what to do more. It seems like the kernel partition is corrupted and cannot be written.
I tried a lot of flashtool versions, FTF files, kernel / boot images, as well as PC companion, EMMA, SUS, ...

I cannot charge my phone correctly since it reboots every 30 seconds

Any help / advice will be appreciated.

Thanks.
Seb

Hi!

I have unbricked my phone successfully by using xflasher and flashing this ROM (https://forum.xda-developers.com/xperia-z/general/stock-rom-xperia-z-c6603-10-6-0-454-t3127499) 1 file by 1 file in a specific order.
(pre-requisite : installed flashtool 0.9.13 drivers and ADB and fastboot drivers 1.4.3)
Thanks

Seb

Hello guys, my ZL C6503 is dead, I have tried everything and did not worked. It was working fine one day and was dead in the other, I think maybe some water got inside, I already used the hair dryer and did't work either.
When I try to turn it on it vibrate once, rests for about 2 seconds and then vibrates 3 times repeatedly. I does the same thing connected to the power cable. Cannot connect to the pc for fastboot, it just keep on with the vibration.
Dou you guys think that replacing the battery will work?

Any help at all will be much appreciated. Thank you.
