Un"Brick" Xperia Z2 - Xperia Z2 Q&A, Help & Troubleshooting

Hi there,
I might have bricked my Phone. It doesn't start, doesn't go into fastboot, doesn't go into recovery.
The only thing, that seems to work, is Flashmode.
I unplugged the battery already.
For the history:
- It ran on Carbon ROM with TWRP 3.0 (I think)
- I installed newer TWRP via recovery, seemed to install fine
- After TWRP Update it didn't start into recovery mode anymore
- Only Boot in Android was possible
- I flashed "Boot img" from the current Lineage OS *.zip#
--> Current situation, Phone doesn't go into fastboot anymore
If I connect it to the PC, i get following messege in Flashtool:
08/013/2022 08:13:15 - INFO - Device connected in flash mode
Is it possible to save the phone?
I have tried some suggestions via the search, but none worked.
Thanks.
By the way I tried several things now. When I plug it in, sometimes the Sony logo appears when "booting" but it gets stuck there. When I unplug the battery and connect it to my computer while holding Vol+, I get into Fastboot mode and can Flash twrp but when rebooting after, nothing happens (red LED comes on for a second or so)

[Q] [HELP] Have I hard-bricked my brand new Xperia Z2?

Okay, I'm not sure exactly what you'll need to know to help, so I'll just tell you what I think is important....
Current situation:
- If I boot the phone normally it freezes at the SONY screen and goes no further.
- If I attempt to boot into recovery mode, it loads the CWM screen (logo in the middle with instructions at bottom), but no actual menu or options. After about 5 seconds, this screen disappears, the phone reboots and then gets stuck on the SONY screen.
- If I connect the phone to the computer in Flashmode Flashtool recognizes it as being connected, but regardless of what I do, after about 2mins the phone reboots, loses connection with the computer, and freezes on the SONY screen as before mentioned.
- If I connect the phone to the computer normally while stuck on the SONY screen, the PC recognizes it though doesn't allow me to do anything to it, and Flashtool says I need to install drivers (I have installed every driver that comes with Flashtool).
How I got here:
- I've rooted the phone
- I've flashed Z2_DooMLoRD_AdvStkKernel_FW-438-v05
- I've unlocked the bootloader (via Flashtool)
- I've installed [Rom][Unofficial]Slim Rom 4.4.4 based on CM11.0, ROM for the Sony Xperia Z2
The phone was okay up until this point, however I wasn't happy with the ROM so I tried to reboot into recovery mode to wipe and install Carbon. This is when the trouble began.
Now it seems I can't do anything :/
Please help. This phone is literally 3 days and it looks like I've completely screwed it >.<
Thanks!

I did try this but can't find a reliable download.
The link posted in XDA forums (http://forum.xda-developers.com/showthread.php?t=2759934) takes me to MegaUpload and for some reason the download always stalls at 44% (I've tried 3 times).
Just soft brick!!!
Just search for ftf and flashtool anywhere in internet

You're on the wrong forum mate, for the z2 go here:
http://forum.xda-developers.com/xperia-z2
Please don't try to flash any .ftf file you downloaded from the xperia z forum, as this would hard brick your phone. Search for it in the link I posted.
Good luck

I'm very pleased to say that this worked. Thanks!
Now, I think I might just persevere with the stock ROM for now and enjoy my new phone.
Thanks again to everyone who helped.

[Q] Need help restoring back to stock from CM12

Guys I need some help here. I just flashed the 0305 build from the latest CM12 nightly. Unfortunately, after updating to this, I can no longer access the recovery. I've already tried flashing TWRP and Philz fastboot and using the m5 settings and twrp manager but I still cant access the recovery no matter how many times I press the up or down button after the purple led light.
I decided to try and do a factory reset but to no avail. After selecting erase everything, the phone just shuts down and when I restart back it does nothing. So I decided to flash back to stock via flashtool. I already installed all the drivers and Its not the first time I used this tool but I get an error that says:
ERROR - Cannot Identify your device
Tried reinstalling the drivers again but the error persists. But a menu for selecting the device manually pops up and then I manually select the Xperia Z2 D65XX option. But now when I continue to flashing the rom, once I reboot to fastboot, I'm stuck at waiting for device.
Edit 1: I tried erasing userdata and cache via fastboot now I'm on a bootloop and I get a red light before the purple light every reboot. same thing with fastboot, I get a redlight first before the blue one.
Edit 2: It seems I got a softbrick

Yes but the device is unrecognized by flashtool

Bricked H960A after root attempt?

Edit:
Problem solved - phone recovered, and rooted successfully. I think the problem was that I didn't use the most recent version of SuperSU. I was using version 2.46 iirc, but I finally got the root working with version 2.76 (filename UPDATE-SuperSU-v2.76-20160630161323). The TWRP version I used is twrp-3.0.2.0-0-h960a.img. (I used this version of twrp both in the failed root attempt as well as the successful one). After I attempted root with 2.46, the phone just hung at the "your device software can't be checked for corruption". To get my phone back, I booted it and connected to USB (you might have to enter fastboot by holding the down volume button and plugging in the USB cable, keeping the down volume pressed until the phone boots, or you might just boot the phone normally and plug it into the USB cable, even though the phone will "hang" doing this, lgup can detect it and you'll be able to "refurbish" with marshmallow kdz which you should have on your computer. I updated my phone to marshmallow before attempting the root, so I had the kdz already. The one I used is v20a. Anyway, after refurbishing, the phone is recovered and usable again, you still get the "can't check for corruption" screen on boot but it only stays for 5 seconds, and then the phone starts. This is normal for an unlocked bootloader. What I did after recovering the phone was to save SuperSU 2.76 (again, filename is UPDATE-SuperSU-v2.76-20160630161323) onto my phone's SD card. Then I reflashed twrp (boot into fastboot, then from console window "fastboot flash recovery twrp-3.0.2.0-0-h960a.img". Then I had to disconnect from the USB cable, and remove the battery. Apparently some phones will perform a factory reset if you attempt a reboot via the console after installing twrp - this is why I removed the battery - then I put the battery back in and booted into recovery mode. To do this (contrary to most instructions I found online which give the wrong button presses), I held the down volume arrow, and then pressed power until the LG logo showed up. Keeping the down volume pressed, I released only the power button, then tapped the power button until I got to a recovery screen (again, keeping the down volume pressed this whole time). Select "yes" both times and you should be in TWRP. Just follow instructions from there that you can find in rooting guides. When you're ready to restart the phone, you'll get the familiar "can't check for corruption" nag screen, but this will go away after a few seconds - LG logo will briefly appear, then disappear and back to that stupid nag screen. But after a few more seconds, the phone starts up. Confirmed rooted with rootchecker!
Below is my original thread where I describe the problem
So I unlocked bootloader, installed twrp and everything fine so far. I put supersu zip file into download folder, flashed with twrp, cleared cache, and went to system reboot - now the phone just hangs at "your device software can't be checked for corruption"
I should say that instead of pushing the supersu zip to sd card, I just saved it in 'downloads' folder of the phone. I also had to do the trick where I flash twrp, and then remove battery, restart phone to recovery mode, because a reboot of the phone would not allow me to use twrp (it just did factory reset)
I can get back into twrp via recovery boot via down volume + power, and I can get into fastboot via down volume + USB cable, but I can't get anywhere else.
I installed stock recovery image from here: droidviews. com/install-stock-recovery-on-lg-v10-using-fastboot/
Went into recovery boot, the android icon shows up and starts to work, but then goes right back to "your device software can't be checked for corruption"
How can I recover this phone? It's H960A
edit:
Ok, so lgup was not recognizing it, and I couldn't install kdz to recover android. I installed lgbridge, then plugged phone in via fastboot (down arrow + usb). lgup then recognized it, and I refurbished with mm kdz. Seems ok now, but still not rooted, and I still get the "your device software can't be checked for corruption" when I boot up (afaik this is because bootloader is unlocked). Tried to root again, same issue. Except this time lgup would not recognize from fastboot, so I just booted phone normally and connected via USB. Then lgup recognized it and I was able to refurbish again
How can I root this thing? at least I have a working phone again

Stuck in bootloop, can't enter Download or Recovery

Hey there,
so I wanted to update LineageOS to the latest nightly (1st August) coming from an April nightly. I did it OTA, entered TWRP, installed the update and got stuck in TWRP, which is apparently a known issue with TWRP 3.0.2.0. But I didn't know that, and tried to fix it by installing a backup of CM 13 WITHOUT wiping data, because I did not want to lose my data. Stupid, I know.
I then found a fix to leave TWRP and tried booting into CM 13 but now I'm stuck in a bootloop. It shows the CM logo, then prepares apps, shows the logo, prepares apps, logo, and so on...
I can't enter Download mode or Recovery mode using the keys and adb/fastboot commands don't work while the phone is turned off or booting.
Any ideas what I can do?
Some more info:
It only bootloops when plugged into my pc. When it's unplugged (or plugged in to just power) it stays at "preparing to start". Sometimes it even leaves that screen but then the System UI keeps crashing leaving me with nothing to do but hard reboot. I still can't Recovery or Download mode tho. And whenever I plug it into my PC, it reboots
So you can't get into downloadmode with holding [Vol Up (+)] and plugin the cable into your pc at the same time?
[Edit]: Sorry, [Vol Up] is the right key.

Switched ROMS (Evolution X -> Nusantara) -> NOW Bootloop

Hi Community,
I read some posts how to fix my Problem, but i cant go to a service Point.
So I was using the Evolution X for a long Time (Installed with TWRP 3.1.0).
And now i wanted to change to the Nusantara Project (Vanilla), I did a clean Flash, everything worked i could access the System.
Than i had problems installing Play Store, so i rebooted into Recovery via the System. But now im Stuck in the Loop.
Can i Somehow connect my Phone to the PC and Reset?
Can someone tell me if i Hard/soft bricked my phone ?
Just a little advice, would be really appreciated.
Thanks a lot
Go to TWRP, wipe system, cache, data and dalvik. Now flash nusantra and whichever GApps are recommended for it (if there are no recommendations then use OpenGApps, make sure the architecture is correct). Now wipe dalvik and restart. Sometimes, certain roms begin to bootloop if you boot into the rom first, then try to install gapps later.
If you still have issues, just reflash the stock rom.
I cant access the TWRP anymore, im just stuck on the Bootloader, no matter how i turn on The Phone (Volume Up + Power ON ), (Volume Down + Power), (All 3 Buttons)
Nothing works anymore i dont understand ....
Im searching the net but i cant go to fastboot or something else, its just keeps on rebooting ...
So it's bootlooping, but you cant access recovery?
When the screen turns off, press the key combo and it should go to recovery.
Your best bet is to take it to a service centre, but if that really isn't possible for you, then wait for its battery to drain completely, then when you plug in the charger, instead of turning the phone on, press the key combo to enter the recovery. From there, wipe and flash some other OS.
I've also heard that certain versions of TWRP don't support some roms, leading to a bootloop. In that case, you'll have to use orangefox recovery to flash the rom (orangefox is flashable via twrp)
Yes its Bootlooping.
When i turn it on, on the Left Corner "Recovery Mode" blinks for one second. Than the usual Text appears:
"Orange State
Your Device has been unlocked and cant be trusted
Your Device will boot in 5 Seconds".
So after a couple of seconds (around 10-20 sec)
It turns off and immediately on again. I Just can turn it OFF when i hold all 3 Buttons.
Than i try starting it with Volume up + Power / Volume down + Power, But i cant access Recovery or TWRP.
So i should wait til the battery gets low and try it again ?
Like i said, my custom Rom (Evolutionx) and TWRP just worked fine. I dont know man ...
Well since your bootloader is unlocked, try flashing the stock rom again. Look for a tutorial and follow it.
Hi I managed to unbrick my device with this guide, and im back on a stock rom
Unbrick
i ran following commands to get to my custom rom:
I run adb reboot bootloader,
add executed following commands.
(Pitch Black recovery 3.1)
- adb reboot bootloader
- fastboot flash recovery recovery.img
-fasboot reboot recovery
It just hang up and booted after a while into the normal system.
But im not able to get to the recovery menu ?
When I restart and hold Volume up + Power, i go in a loop and the phone keeps restarting over and over again.
what have i Fu**ed up ?
Do i need another recovery tool ?
sorry guys, i appreciate your help a lot tho !
EDIT: Is my bootloader unlocked ?
I can access via "adb reboot bootloader" the phone
and on the blackscreen on the phone it is written:
oppo verfiy pass
fastboot_unlock_verify ok
Update:
So i tried some Stuff and i got Red State. No Problem i Unbricked it once again and now im on Stock Android 10.
Now im Trying to enable the bootloader again.
I downloaded the In Depth Test_Realme_6.apk but i keep getting the Error that i should update the system.
So should i update the system ?
I cant find a CURRENT Tutorial to make this work, please help...
If you cant find a tutorial for your version, why not downgrade back to a previous one if possible.
