Z3 in bootloop - Xperia Z3 Q&A, Help & Troubleshooting

The device just keeps rebooting endlessly, I flashed moonbreaker rom and when rebooting the device this happened.
No idea what to do to resolve it, please can someone assist me, the device is completley unsuable. Only option is to return it and hope for a new one I'm guessing?

It would be better if you asked in respective ROM thread ,not opening a new one, just sayin..
You can either :
- enter recovery,flash disable exposed zip,you can find in moonbreaker thread,and see if it solved it.
- clean flash prerooted rom ,you can find one in general section
If all fails,you can enter fastboot mode and flash ftf via flashtool or even try with PC Companion if everything else fails.There should be a repair option within PC companion,haven't used it though,but you should find it easily.

I went into twrp and factory reset the phone and it is still broken! i really need someone to help me im very stuck here!!!

Can you report the exact steps you took prior to this happening? Which files you flashed and in what order? Also which version of the Z3 do you own?
Have you tried restoring a nandroid if you made one?

If your boot loader is locked you can just repair with pc companion.

[Q] Xperia Ray st18i booting prob ..

Guys , I was on Jelly Sandwich with sirikay's kernel. I had some speed problems with wifi. So I thought of flashing stock ICS Rom ST18i_4.1.B.0.587_Kernel.ftf using uniflash.exe and did it. After flashing it didnt restart. So I clicked the power button to restart manually but just got a vibration sound and nothing else .. just the blank screen. So I searched for stuff about unbricking my device since I thought it's bricked. I downloaded this package "FlashTool_0.2.9.1_FOTAUnbrick.exe" and started flashing the firmwares. So I held down my volumedown button and connected it to the usb port. It says error and that I have to select usb debugging mode and connect again but I can't even start my mobile.
Plz help .. Thanks in Advance
Try using flash tool!
and flash stock ftf through that.....

Hi
I confirm, just had the same problem while updating a custom ROM.
Get the Stock ftf file for your phone/model then use Flashtool to flash it.
Search the forum for the proper links there are likely to be all there somewhere
Hopefully, your phone will be back to life on a stock version.
And yes, if you want to re-install a custom ROM you need to re-do all the process: root, (optional) unlock Bootloader etc.
Good luck.
PS: I saw a thread saying to use the SEUS to restore the phone to stock. Worth a try but for me it didn't work since SEUS was telling my phone already had the latest version. Fix hard bricked ray

[Completed] Asus Padfone X - soft-bricked

Hello,
thank you for taking the time to read and try to help.
I got an Asus Padfone X from At&t and the refused to unlock it
Asus didnt help either.
not to bore you with details
but here is my noobish mistake tool form, i flashed the asus kernel .zip file to the bootloader using twrp.
now phone wont boot into recovery or bootloader
got the minimal tool which as you know include fastboot and ADB
but it wont detect the device ( it detected it before when i rooted the phone )
I made a backup before i flashed , but the problem i cant flash it to a device that wont go to bootloader or recovery
and wont be detected by ADB.
please guide this lost noob.
Hello Ultimician,
If your device cannot boot into recovery or bootloader it's a hardbrick. Flashing the wrong kernel will cause your device to hardbrick.
You probably still have a warranty, I'd go to your service provider and play dumb: "One day my phone just didn't turn on, I've tried everything even charging it."
If you know of someone that could JTAG your device you could go to them that might work, what the manufacture usually do is they replace the whole motherboard. ( What Samsung did when I bricked my device in any case.. )
Otherwise you could refer to these threads, be careful though they are not necessarily for your device. ( But they might be of help )

thanksfor the swift assistance
thank you kindly
amazon offered me a refund
i will take my chances
Carefully when they send a device back to the maker they can often pull information.like last install and all of that. If you had a back up. I would try to flash the stock firmware. They are ways to do this with jig and other tools. I would try to flash stock every way I could before I take it back. I had s3 and bricked it long time ago.after many hours of reading I fixed it. Please always when flashing make sure it's for your device. Wish you luck2

Any way, everything was going perfect (i have flash like 5 Android phones with no problems at all)
but when I was finally flashing the room I copy the worng file in the device, It was an error grabbing a file that was for the Galaxy s4 gt9500, so while un TWRP, I started flashing this file, a few moments after the program started, it asked again if I wanted to continue and I notice at that time that I was about to flash a totally different room, so I click cancel.
ok, so right now The phone wont start, I am following this guide
http://forum.xda-developers.com/showthread.php?t=1849170

I tried to flash the stock firmware and the kernel for my LT26ii but short after the process starts, I get an Error message
I hope that someone can help with my case, I dont know if it is posible to transfer the correct .zip file to the phone in TWRP mode
Thanks in advance!!

Try to fix Softbrick? with wrong flashed Firmware Xperia Z3

Hello XDA Team,
so to get exactly to the thing I try since 5 hours of searching and trying. I had Cyanogenmod installed on a Z3 (D6603) and wanted to flash is back to an original pre rooted Firmware. Stupid as I am flashed it with the ZIP for Z1 (C6603) because I didn't though about it much and overread it and then Wiped the Cache. After the "reboot" nothing showed up. Now I'm getting nothing, literally nothing. Screen doesn't show anything, no LED, and my PC cant find the phone. Already tried to reinstall the drivers from Flashtool.
To summarize: I cant get into Fastboot nor Flashmode but I can turn it "on" and shutdown with the Yellow Button.
I really just need to get into Flashmode to flash it with Flashtool.
Hope someone can help me, send a link to a thread I overlooked or say that I got a hardbrick.
If it doesn't belong in here pls say me where I should post it instead. :silly:
Have you solve your problem?
Thats is a Hardbrick

Softbricked Xperia Z3 - locked bootloader, disabled USB debugging, no recovery access
Hey, I'm in big need for help in reanimation of my Xperia Z3. I've been trying to install CM 12.1 on rooted Lollipop 5.0.2. In TWRP, after doing a full wipe I've checked ROM on sdcard and started installation. After some time, phone prompted sth like: "there's no root acces, click ok to install SU". Guided by intuition rather than by wisdom I've clicked it, and here started my problems. After reboot phone was stuck on Sony logo screen. So, I've do some research and started to apply solutions one by another.
- After trying to manually access recovery mode, there's only a short flash of green LED and that's all, black screen. Propably there's no more TWRP aboard. Other ways to access it are blocked: I can't use any apk because of softbrick, and can't use ADB commands because USB debugging is disabled after wipe.
- I can access fastboot mode visible for Flashtool; when phone is in this mode, blue LED lights permemently. I've tried to unlock bootloader: program gives message, that there's no possibility of it on my phone. By the way, I would prefer to stay with blocked bootloader. I was trying to flash custom kernel, but there was an error. I don't remember exactly what it was, but it was about lack of permissions, i think that it's also because of USB debugging disabled. The same error shows when I'm trying to flash any other ROM - stock 5.0.2, prerooted 6.0.1 or Paranoid Android.
Most of solutions in similar topics around the web tells to use recovery mode, Flashtool or ADB commands. All af that failed for me and I'm stuck with no ideas what to do next. Now I'm trying to repair or recover stock, unrooted ROM with Xperia Companion, but I'm really afraid of this process because I can't check battery or load it normally while stuck in boot loop. Maybe it will help, then I'll edit or delete this post. I hope you can help me somehow.
Thank you in advance and best regards,
BW
