Guys, I just got stuck in fastboot mode and I don't know even why. I was re-locking my bootloader, everything went normal, no errors, nothing. I did it via Flashtool, and now I cant boot up the phone. I re-locked the bootloader because I was trying to restore the device with XPeria Companion. When I tried to boot it up disconnected from a pc it will just vibrate and wont boot up. When I try to boot it up connected to the pc it will boot just in fastboot mode, with the green led and that's it. Nothing.
I was running Carbon ROM with the kernel included on it, XPosed and some modules and was rooted with Magisk.
Please help me, I'm in deep **** right now

after lots of reading i decided to try out cyanogenmod 12!
after full backup (even ta-partition) i downgraded my z3 to .93 and then root it succsesfully with giefroot!
everything went fine until i tryd to install the boot.img over fastboot....
i dont know exactly what went wrong but now the normal boot hangs on the sony sign and if i want to boot into flashmode (vol+ & power on button) it just throws me into fastboot mode! so i kinda stuck here and dont know what to do
how can i get out of fastboot mode? what did i wrong?
please help!
a fastboot devices gives me a device back
an adb not
i hope there is some recovery option from fastboot
It sounds like you didn't unlock your bootloader? If so either try to unlock it with flashtool (just search for a tutorial on XDA) or reflash an official fw with flash tool to recover your device.
You should be able to enter flash mode by just pressing volume down (powered off device) while plugging in the USB port.

Not only does it sound like you have not unlocked the bootloader, but you probably have not backed up your TA, as you said you did that before you downgraded and rooted, however, you have to backup the TA partition AFTER rooting and BEFORE unlocking
Hi,
this is what happened.
I unlocked the bootloader of my z5, afterwards I flashed the twrp recovery.
After that I rebooted my phone and it only hangs on the kernel screen, it wont enter recovery neither boot into system.
Then I tried to flash the stock rom with flashtool but it wont go into flashmode either.
Tried it even with fastboot mode and nothing.
Any suggestions?

After unlocking the bootloader you should have flashed a custom kernel like Androplus V36 first before flashing the recovery img.
I had a similar case I think but with my old z1 compact. When you connect your phone via usb, is anything happen? What color is the led?
What I did was just make sure fastboot and flashmode drivers are installed. Kept plugging the phone while pressing volume button up and down and keep playing with it.
Make sure battery is fully charged and maybe try a different cable if you have another one.
If you succeed and manage to get into flashmode then reflash your ftf file and then let it boot.
If all is good and well, then download androplus kernel for example and extract the boot.img
http://forum.xda-developers.com/xperia-z5/development/kernel-andropluskernel-v1-t3246100
Install minimal adb and fastboot and connect into fastboot mode
Place the boot.img file extracted from androplus kernel in your minimal adb folder and type fastboot flash boot boot.img
if it says okay two times u can then flash twrp recovery by using the command fastboot flash recovery twrp.img where twrp.img replaced by the name of your recovery img file.
Sorry if im not clear enough, but I hope this helps you.
Well, the led only flashes shortly in red, after that comes the kernel bootlogo and nothing else.
When the bootlogo shows up the is not flashing in any color.
When I try to connect it to pc it wont recognize it, and the phone starts booting and hangs on the kernel bootlogo again.

Have you tried connecting and opening xperia companion to see if you can do a software repair there?
Or else, I would just leave it connected to a charger for the night and try again, and just keep playing with the volume up and down button while connecting it.
Also you can try installing your drivers another time, and try an older or newer version of Flashtool.... this has helped a couple of times too for me in the past so thats another thing you could try.
Good luckk:good:
Well at this moment my pc just decided to recognize the device so I am flashing now the stock firmware ATM
Thanks for the assistance

Good to hear you revived your phone
Remember if you wanna flash custom kernel:
First unlock bootloader if it isnt ofcourse
Via minimal adb and fastboot flash boot.img from a custom kernel of your choice, I would recommend androplus kernel v36.
Next you could flash a twrp recovery.img via fastboot right after flashing the kernel, but I would first boot the system for a time to see if it boots okay.
Good luck

Hi! I'm kind of new to this so please forgive me (done once before with a few problems).
Basically, I was looking to root my new HomTom HT16 with SuperSU by downloading a custom recovery (TWRP). I rebooted into bootloader with USB Debugging enabled and OEM Unlocking enabled too.
I selected Fastboot mode from the menu in the bootloader and plugged my phone into my computer. I had no problems recognising the device. I followed the bootloader unlocking steps with:
{fastboot oem unlock}
The instructions that I was originally followed told me that I had to use the Fastboot command (with the recovery.img being TWRP):
{fastboot flash recovery recovery.img}
I was told nowhere that I had to clear any cache partitions (still not sure if I had too). Everything I did seemed successful until I was told to take the battery out, put it back in and turn the device on. It brought up the "HOMTOM" text for the boot screen but instead of booting, it repeatedly turned off and on. Because none of this actually worked, it didn't actually flash the recovery, and so I couldn't boot to it. It just got stuck in a boot loop.
I searched up how to fix a bootloop and I could find anywhere a solid solution unless I just wasn't looking properly. I have all the factory ROM files, I just don't know how to use them to replace anything that could be corrupted. I flashed back the original recovery.img but it still will not turn on, it just says on the "HOMTOM" text screen for a very long time. The recovery also doesn't work, it's just an image of broken android with its internals showing.
Does anyone know what to do now?

Do you say you have the original files if yes, then if your device is a Mediatek device use SP Flash Tool to flash the rom. If you still need help contact me here or on [email protected]
Hi, i hope someonecan help me, i was to root my phone, an xperia E, i've done it before with a thread i found here, i did everything ok and it worked but i had to flash the stock room so i could install magisk root but i made the mistake of try flashing the recovery before flashing the Boot.img so now every time i try going into fastmode using thecomand "adb reboot fastboot" the cellphone restarts normaly and by holding volume down and then conecting the usb cable, the led goes red as fastboot and then goes green and the computer does not recongnize the device.
i have all drivers installed, i repeat, i've done it befor and it worked, but this time i forgot to flash the boot image so i think is because of this.
Thank you for your help
I'm sure my drivers are fine cuz i messed this up via fastboot.
so i got android 10 on my op7p. There were some magisk modules that caused a bootloop. But i cant uninstall those modules without twrp. So i decided to flash twrp into a boot slot via fastboot. then, i set the active-slot to that. but then I still don't get twrp idk why. Now, I can get into fastboot but my pc doesnt detect it, I cant boot into the system either. The only thing my pc detects is when i power the phone off and plug it in, it automatically boots into the unlocked bootloader screen and gets stuck in there. PC detectes an "unknown usb mass storage device". HELP!!!

How did you flash twrp? On A/B devices like the OP7P you can't simply fastboot flash twrp since that will cause you bootloops. To install twrp you have to fastboot boot the image and when TWRP is booted you have to flash the installer zip file. Since you are now stuck in a bootloop, you can try to recover your boot image with something like this https://forum.xda-developers.com/on...isk-patched-boot-image-oneplus-7-pro-t3964345 (no guarantees on this).
Fastboot flash this image and see if you can boot again. If that does also not work I believe the best thing you could do is reset everything with the MSMDownloadTool.
Did you use this command: fastboot flash recovery filename.img?
If yes, you'll have to use MSM to restore it
