My cousin has an xperia z3 dual d6633 we wanted to root it so what we did was :
1- we unlocked the bootloader using sony's official guide that was a success
2-we flashed twrp using
Code:
fastboot flash recovery TWRP.img
That appeared to be a success but we failed to boot to recovery i tried everything to boot to recovery from pressing power buttons with each volume buttons or both to even using
Code:
adb reboot recovery
and even that didnt work it always booted to android
3- when that didnt work one guide on the internet said to boot directly from the twrp image i had on the pc using
Code:
fastboot boot twrp.img
and thats where things went south it still booted into android but this time it was stuck in a bootloop it would boot into the screen thats right after the sony logo (the one that looks like the ps4 booting screen) and it would keep doing the animation non-stopping
4-we tried using xperia companion to fix it but it always said bootloader was unlocked
5-we tried relocking the bootloader using both
Code:
fastboot oem lock
and
Code:
fastboot -i 0x0fce oem lock 0x<unlock key>
mimicking the unlock bootloader command from sony's website but the lock bootloader keeps going on forever nothing happening until we take out the usb cable then it says failed
now i have two questions
1-can this be a hardware problem? Basically can the steps i made damage hardware?
2- is there a way to either relock the bootloader to fix it using companion app or fix it using any other program at all?
Thank you for answering

I've android PumpKinx 10.1 tablet with 5.1 Lollipop android os.
I did take backup of its stock recovery image.
Since there is no custom recovery image for this device I tried to flash it with twrp recovery image. But after running below command, device goes into bootloop. I've tried many methods but no success.
fastboot flash:raw boot twrp.img
Any help would be highly appreciated. Thanks in advance.
maybe u have locked bootloader. First turn on oem unlock in developer options, then reboot in bootloader and type
Code:
fastboot oem unlock
Then confirm acion in the tablet whit volume up, then the bootloader now is unlocked.
Note: The tablet get soft reset. Make backup first.
Then try flash the recovery

Do you understand boot loop or not? First of all fastboot is already unlocked otherwise how I will be able to run above command and since my device is in boot loop then how can I go to developer option?

Just send them an email asking for stock firmware with flash tool, along with the purchase bill..
Or if it still has warranty, just go to the service center and say something like you over-charged the phone a complete night & since then it's not working and claim warranty..
Have you tried to wipe the cache partition or even factory reset???
Ive been asked by a friend of mine to fix his nexus 5 that is stuck on a Bootloop, I've opened it up to have a look at the power button and that wasn't the problem, the device has not been rooted, the Bootloader is locked, there is no emergency mode and there is no recovery. I am however able to access fastboot and when I try unlocking via fast boot it does unlock but then requires a full reboot and as I've said before this cannot happen because of the Bootloop.
Any suggestions!?!?!?!
After unlocking the bootloader, does the bootloader relock itself? If it does, the memory chip is damaged and requires a replacement motherboard.
I've had this problem when I corrupted my recovery by using FlashFire and my bootloader was locked. Though I was able to restore my device using Fastboot. I had unlocked my device and instead of flashing the stock recovery when unlocking the bootloader I had flashed the Team Win Recovery Project recovery and when I tried to boot up to TWRP recovery it would stay for a couple of second displaying that it couldn't wipe the data partition and then reboot me back into bootloader mode. I fixed that when trying out the following steps:
1= Download the latest firmware of the device found Here .
2= Boot the device to Fastboot mode (aka Bootloader mode) plug the device in and unlock the bootloader (of coarse confirm when asked by the device).
3= After seeing that the device has stopped wiping data indicated the text "wiping..." in the very bottom of the specifications in the Fastboot Bootloader REBOOT THE DEVICE IN FASTBOOT BOOTLOADER MODE by navigating using Volume buttons to scroll down and highlight the option "Reboot Bootloader" and then pressing the Power button.
4= Using the provided scripts for Windows , Mac and Linux flash the device with the firmware.
VERY IMPORTANT: WHEN YOU SEE THAT IT IS FLASHING "userdata" and after that "cache" HOLD DOWN THE VOLUME DOWN BUTTON THIS WILL FORCE THE DEVICE INTO FASTBOOT BOOTLOADER MODE.
5= When you see that the device is in the Fastboot Bootloader mode scroll down (again using volume buttons) and highlight "Recovery Mode" then boot into Recovery and it should automatically start wiping the ("userdata" partition) Data once more that the bootloader said when it displayed the "wiping..." message after being unlocked.
If not wipe data factory reset the device manually by using the recovery and reboot to the system.
Optional: 6= IF the device has successfully booted up power it back down and lock the bootloader again using the fastboot tool additionally before locking the bootloader you can reset the warranty tamper flags.
This tutorial explains in detail how to flash a firmware to the Nexus 5 and shows how to restore the tamper flags.
I hope that I helped in some way.

Yes after unlocking Bootloader and restarting the device into the Bootloader it relocks and I'm back at square one
The motherboard needs to be changed. I recommend looking for a used Nexus 5 with a smashed screen and a working motherboard as this may easier than trying to find a new motherboard.

Thanks for the suggestion but I've tried this already and it doesn't work because when I unlock the bootloader and reboot into the Bootloader it locks itself again making impossible to flash the system image
Hello, I have problem with my softbricked Nexus 5.
phone is full stock
bootloader is locked
USB debugging is not enabled
Android 6.0.1
all buttons are working
USB socket is fine
Factory reset from recovery mode is not working - still bootlooping
My purpose is to bring it to live, but I am stuck. Due to locked bootloader I have to use LG Flash Tool. Some time ago I used it with my other Nexus 5 and it was fine - worked excellent. Now I want to do it again with other phone but I am stuck on start: Can't enter download mode (volume up+usb cable). When I am trying to enter to download mode,charging battery icon appears and after few seconds my phone is being recognized as MTP USB device in device manager. I thought it is a problem with the phone, but tried with another working Nexus and there is no difference - it looks like problem with phone-pc connection to me. I tried few cables (original samsung and nokia) and two pc's - no difference. Tried all USB ports etc. Clean reinstall (with registry keys delete) doesn't help, updated version 4.2 neither. Do you have any ideas how to fix it?
Download mode? Never heard of that on the Nexus 5. There is a fastboot mode for flashing stock ROMs and to unlock the bootloader.
I recommend unlocking the bootloader and using NRT to flash a stock ROM.

I have NRT but problem is that to unlock bootloader I have to enable USB debugging - I can't do it with bootlooping phone.
Bootloader can be unlocked without enabling debugging as you are not running adb commands, you need to run fastboot commands.

Thanks! Can I do it with NRT also?
Easiest way to unlock the bootloader on a windows machine is to do this:
make sure that the necessary fast boot drivers are installed;
boot phone into fast boot mode by holding down volume up, volume down, and power;
connect the phone to the computer;
type "fastboot oem unlock" without the quotation marks and press enter key.
Unlocking will wipe the phone.
Once unlocked, you can flash a stock ROM using fastboot commands.

Ok I did it. Do I have to proceed "fastboot reboot" command? when I am doing it it reboots and still bootlooping. When I enter bootloader it is locked again
If the bootloader relocks itself when the phone is rebooted, the memory chip is damaged and will need a motherboard replacement.

I believe that relock is impossible and but to make the device recovery to installed status of stock rom keeping with unlock bootloader.
Please see my post. May make it help or not.
When I try to burn rom with TWRP, img burns but it doesn't start and zip gives an error and cannot burn.
When I first burned custom ROM (unofficial AEX), it did not start, so when I deleted the data from TWRP, it seems that I deleted things that should not be erased, so even if I burn it from the zip file, with the error message in the image below I...

I've recently bricked my device trying to install LineageOS, long story short I had to use MSM Tool in order to flash a new, stock ROM. Since I did that I am unable to unlock the bootloader: everytime I do the phone bricks with this following Yellow message on the screen: "upgrade download failed please check your download flow is right". After that I have to use the MSM Tool again to unbrick the Yellow text.
Any ideata how I might unlock the bootloader? Aside from that, the phone works fine.
EDIT: I managed to fix this by OEM updating my device to Android 11 and *then* unlocking the bootloader. Another issue has arisen now, though: whenever I try to boot TWRP from fastboot, the phone reboots and gets stuck in the "Fastboot Mode" OnePlus logo screen. Would anyone know how to fix this, or maybe is there a way to root your phone without using a custom recovery?

Yes you can ,,install thru boot loader with ADB and fastboot CMD. First you need to extract the boot.img from your oos rom, patch it in magisk app, then put it in your adb folder and run the cmd " fastboot flash boot boot.img .
