usb debugging turns on automatically - Sony Xperia XZ2 Questions & Answers

Hello. I use xz2c(H8314), usb debugging turns on automatically after every reboot and it's really annoying.
What I did actually:
Unlock bootloader -> not happen
Install TWRP and not bricked -> not happen
Want stock firmware and do 'something'(can't remember what I did) with flashtool; I think this is the cause of this mess
Flash new firmware by EMMA -> yes
Flash new firmware again by newflasher -> yes
+add
Flash AOSP -> first boot : yes, turn off in developer option and reboot : no
I've already googled much but there's no sharp answer. Things like reset things.
And what I found another is when I connect my offed phone to pc, It automatically connected in flash mode(weak green led). This can be related to this problem.
Help me! or I have to go sony cs:crying:

Holy cow! I wrote in xz2 forum not xz2c. Excuse me with an open heart

[Q] Help with root

Hi,
Just got my new ZR and it came with 10.3.1.A.0.244
I need to root, so I can restore my app's data from my old phone (Xperia SOLA) via Titanium.
I started by following this thread and doing as advised:
- install USB drivers (Z, A, fastboot and flashmode)
- change USB mode to MSC
- activate debug over USB
- install Flashtool (upgrade in my case)
- restart phone in flash mode
- use flashtool to flash XperiaZ_C660X_KernelOnly_10.3.A.0.423_Generic_NL.ftf
- flashtool says it succeeds, to remove cable and start phone
That's where it gets stuck! The phone doesn't wake up. I remove the battery, press the power button for a couple of seconds and it vibrates and ... nothing else. If I hook the phone into FlashTool, it says the phone is in flash mode.
I've tried flashing the XperiaZ_C660X_KernelOnly_10.3.1.A.0.244_BE.ftf, but nothing works.
I bring the phone back alive by using SUS, but I'm back where I started. I've done this 3 times, and redownloaded the FTF 2 times.
What am I doing wrong? I'm still on locked bootloader. The phone has less than 24 hours... hasn't seen water yet :cyclops:
Wanted to test a couple of things, before voiding my warranty!!
If anyone has any ideas/sugestions, I'd love to hear them!
Hajah
Dude, XZR is C550X, you're flashing C660X which is XZ's kernel...
Follow the instruction here for root in 4.1.2 -> http://forum.xda-developers.com/showthread.php?t=2384590
If you're on 4.2, you can try follow here but it seems still buggy -> http://forum.xda-developers.com/showthread.php?t=2387008
Hi,
I see now where I got mislead... (n00b)
As I see it, no valid method to get root on 4.2!
Can I flash 4.1.2 on my locked bootloader? And where do I find the correct ROM image for my C5503?
Thanks again!
------------
Found it! It was hiding behind a spoiler box in the 4.2 thread
Hajah, the C5503 n00b
try
try using doomlord rooting kit download it and connect your phone to your computer install driver if you want start doomlord press any key to continue it will automaticaly restart when it has finished
Yes, you can flash any firmware without unlocking your bootloader.
You can get all 4.1 and 4.2 stock ROM from different region in this thread
http://forum.xda-developers.com/showthread.php?t=2384512
You can try to root your 4.2 using the method, some reported to be successful.
did it work
did it work dude cause it works on all devices:fingers-crossed:
tam Esument
is there a quick and easy method to check if the bootloader is unlocked or not?
See this post.

Manual Software Update without root/keep warranty

Hi all. I'm a long time Samsung user, and been hanging around the forums for a reasonable amount of time but my wife recently got a Z3 compact and I'm clueless when it comes to them.
Basically I'm looking for a way to manually install a software update, as my phone SP hasn't yet released their version of the update out.
Anyone from the Samsung world - I'm essentially looking for the equivalent of DLing a rom from Samsung Firmwares and using Odin to install it.
Is this possible at all on the Z3 Compact? Any help would be great, as Telstra are terrible for updates.
Of course it´s possible only you need Flashtool http://www.flashtool.net/index.php and TFT file(firmware for Z3 Compact) you can check the last release with XperiFirm http://forum.xda-developers.com/cro...xperifirm-xperia-firmware-downloader-t2834142 or you can check here too http://forum.xda-developers.com/z3-compact/general/list-stock-firmwares-d5803-d5833-t2906706

Cheers guys. Do I need an unlocked bootloader for this? Does that void the warranty? If not, how do I unlock the bootloader?
Sorry for the noob questions, really have no idea how to do this stuff with Sony, just know my i9XX series Samsungs!
Grr I downloaded everything, but I can't get the device to boot into flash mode.
I've installed Sony PC Companion previously, and tried to download a fastboot driver (which is just an inf), then with the phone off, I hold down volume down and plug it in. I see SOMC Flash Device, but the second that I let go of vol down the device reboots into normal mode and I never get the green LED.
The fastboot driver I have is this: http://developer.sonymobile.com/downloads/drivers/fastboot-driver/
But when I download that, if I try to update either SOMC Flash Device OR Xperia Z3 Compact drivers with it, but say that the folder has no compatible software driver for my hardware...Any ideas? I can' t believe I'm having so many issues just getting this thing into download/flash mode!
EDIT: Just realised that I was trying to install the fastboot driver, instead of flashmode.
So what do I do to get the phone to stay in Flashmode?
EDIT2: So I've found the driver install in the flashtool director, and ran that, installed the drivers, but still I can't get a green LED...
I can get it into fastboot mode (and the blue LED stays on, PLUS Flashtool detects the phone. Can I flash from fastboot mode?

You don't need to unlock the BL, you only do that when you want to use a different kernel. If you're planning on using a different kernel, please back up your TA partition first (after you're rooted) after that you can unlock the BL.
Backing up your TA-partition makes sure you don't lose your DRM keys. (Losing your DRM keys will void warranty)
No idea about the fastboot driver, I think Flashtool also gives you the option to install the drivers, so I'd say install it through Flashtool.
This is driving me batty!
I can get the phone into fastboot mode, but to flash in fastboot mode, I'd have to flash the .sin files one at a time - which I don't want to do! But I jsut can't get fastboot to recognise the device in flashmode to flast the ftf file whole!!
Are you using Flashtool to install a new FW or something else?
Yeah, to install a new firmware...I ended up doing it in a very unorthodox way...
I noticed when I plugged the phone up holding vol down flashtool would detect the phone to start with, before it either turned off or restarted itself. So I tried to flash the ftf, and said I need to attach the phone in flash mode, so I tried unplugging it, and holding down and plugging it back in, and it started flashing. I had to hold down volume down for the duration of the flash though, as I was scared it was drop out of flash mode mid way through

Enable USB debugging. To do this, spam the build number, after dev options are on, go to them from settings and find USB debugging.

Z3 Compact stuck on bootloop no recovery

Hi guys,
So I'll tell you the whole story here. I was on Lollipop, fully rooted with working XZDR recovery but phone seemed laggy so I decided to give it a full format with the newer firmware. So I backed up everything. Booted into recovery. Formatted the whole phone, then took out the SD card to load on the zip file from the PC. On inserting it, it wouldn't be detected so I tried to reboot into recovery using the inbuilt option but forgot that recovery too would have been deleted. Since then its just stuck on the Sony logo. It reboots by keeping the Power button and Volume Up pressed, but to no avail. I tried to flash the image using Flashtool but it doesn't recognize the phone when I try to connect it in Fastboot using the Volume Down during Reboot method. Nor do I get a blue LED on the phone. I guess it isn't entering Fast boot.
Please help out since its my daily driver. Help appreciated. Thanks
Oh hey guys managed to restore using Flashtool. Tried booting phone into Flash Mode again and idk how it worked this time. Breathing a sigh of relief.
Could you please explain in detail how did you managed to get out of bootllop....it seems i sucked exactly like you & now clueless....
First of all, try repair it with Pc Companion. If that doesn't work, try with flashtool.
Keep in mind, to enter flash mode, press volume down button and insert usb cable.
tried PC companion & got error 2003 (Unlocked Bootloader & rooted wont work it seems)
Flashtool, will give a try again....
As of now, i am able to go to the fastboot & can open files on my PC when connect phone via USB cable....
Phone not booting up normal/recovery mode....It just stucked with boot loops
Tried flashtool---Ended up with errors as attached pic
As i cant bootup my phone...USB Debugging option cant be ticked
I was running SlimLP (unofficial) while bricked my phone....
Anything on that please....

Try installing Flashtool ver 0.9.10.2beta4 - you can see in this tutorial section #5: Device connected with USB Debugging off, ergo you dont have to have USB Debugging on: http://forum.xda-developers.com/xperia-z/general/tutorial-how-to-flash-stock-roms-t2240614

Not sure what you mean....... all I can say is, Flashtool 0.9.10.2beta4 does not require USB Debugging to be turned on to work and I definitely didnt turn USB Debugging on before starting the root process. Later yes but not before.
Try it or not, thats up to you.....

[Q] Sony Logo Bootloop !?

Hi all,
So I got this Sony Xperia SP C5303 from a friend of mine which is stuck on a boot loop (SONY logo => XPERIA logo => Orange logo, then screen dims and reboot )
I tried to flash it with FlashTool but nothing, I downloaded the ftf for it and I have installed all the drivers from the flashtool driver folder but nothing, I always get an error on Flasgtool indicating that I must install the drivers
As I said, the phone cannot be booted and I have never connected it to my computer so there were no previous drivers, so what should I do ? (I have Win 7 btw)

Don't know what you mean by all but the three necessary ones are fast boot, flash mode & viskan board drivers. Use the latest version of Flashtool, install those drivers, prepare the firmware and connect the phone pressing the volume down button.

I do have FlashTool the latest version (0.9.18.6) and what I meant by "all" is that when I run the "FlashTool drivers" that comes with the software, it gives me a checklist of the available drivers, I ticked every single one of those drivers, and they're all installed, but still, FlashTool shows an error that the driver must be installed !

You don't need to install all of them, just the three I mentioned. Could possibly be causing detection issues.
Go download USBDeview and see what you got installed. I'd advise you to remove everything Android and Xperia related and start from scratch to avoid conflicts. If you have installed things properly, you phone should show up as something like this in USBDeview -
Normal mode
Xperia SP - USB Composite Device
Fastboot mode
S1Boot - Fastboot Android ADB Interface or ADB Bootloader Interface or something similar.
Edit : Just as I finished posting, my SP wasn't getting detected in adb. Why? Because I had connected my brother's Xperia ZR and for some reason my phone doesn't like other phones being connection on my machine It was showing up as Linux storage unit or something. Reinstalled drivers via FlashTool and everything's good again. Drivers are finicky things man.

LOL, well I've got a little update
I flashed the phone first with Sony PC Companion, after it finished, I plugged out the phone and started it, it took some while to boot, the screen showed up but it wasn't responsive, after a couple of seconds, it dimmed and it rebooted and now it's back to the same old issue (SONY > XPERIA > Orange > Reboot).
Right afterwards, I flashed it using FlashTool (This time it worked perfectly, which is weird) but still nothing, after finishing the flash and plugging out the phone, it's stuck on the SONY, XPERIA and the colorful waves bootanimation ....
I've no idea what is wrong with this thing now

Well the fact that it's getting there means there isn't anything significantly wrong with it.
Have you tried rebooting it using the off button at the back? Sometimes it does that the first time booting into the ROM. Just press and hold the button for a few seconds with a pen or a toothpick to reboot the device.
You could also boot back into recovery and do a factory reset just to see if it helps the cause.
You can also try different firmware versions. Maybe 4.1.2 instead of 4.3.
BTW is the boot loader unlocked on the phone?

I did try the tiny yellow OFF button in the back several times through the flashing process and whatnot, but nothing .
I tried getting into recovery mode but it just won't it just keeps on doing the same bootloop as before
I dunno if trying a different firmware would help, I highly doubt it but I will try it as I got nothing to lose
I've no idea what that boot loader is but I DID try to unlock it using FlashTool's BLU and I got this in the log "07/029/2015 21:29:05 - INFO - Your phone bootloader cannot be officially unlocked"

You need to press either the volume up or down button a few times when you're booting up to get to the recovery. If you have done it right then after the Sony splash screen you should go into the recovery.
Boot loaders need to be unlocked to be able to flash custom recoveries & ROMs but forget about unlocking the boot loader for now since you do not know what it is and without your phone working there's no way of knowing for sure of it can be done or not.
Like I said try doing a factory reset in the recovery or a different firmware to see if it helps.

Well, I just did some research and I found out that Sony phones do not have a stock recovery mode . . . So there's no recovery mode for me (I did try but nothing)
I'm going to try to unlock the boot loader using SDK and if nothing happens, I'll try to flash it with a different firmware

Oh damn I forgot you had flashed stock firmware...yeah Sony phones ship w/o a recovery. Even if it had one, it wouldn't be much use other than wiping cache & dalvik, factory reset and installing official signed updates. A big reason why people unlock their boot loaders to install a custom recovery.
Before you proceed try to understand as much as you can about what you are doing. Don't go in half cocked and create more problems for yourself. The main problem you face is that you don't have a working system so
a) you don't know whether you bootloader can be unlocked to begin with and
b) even if it can be, you can't take a TA backup to save your warranty cause your phone's not working. If you don't take the backup before the first time you unlock, your warranty's pretty much gone forever.
If you still wanna proceed, check out the link below. Another poster wanted to unlock recently so the thread below contains boot loader unlocking instructions. There are four I have listed. Read carefully before you proceed.

Xperia SP almost dead after flashing. Need help.

I flashed my Xperia SP with from Jellybeam to CM13 rom. I didn't create any backup, wiped clean everything including cache using twrp recovery. While the setup installed CM13 without any error but I downloaded the wrong gapps and the setup didn't accept those. So I chose to reboot the cell and since then it just stopped responding. Although it is showing the green led while plugged in via USB, it won't start in neither fastboot nor recovery mode.
I'm stuck here and have no idea what to do.
I tried installing PC companion, flashtools, SP flashtools, emma, everything. None of these detect my cell. I'm using Windows 10 (64 bit) and am at a dead end.
Any help would be appreciated.
UPDATE:
I managed to flash it with errors and now it's stuck in a SONY logo bootloop. Its starts, shows SONY logo for a while and then turns off again. Again it's not getting recognised by any flash tool, sony companion etc.
Help please.

Whether I try to flash it or unlock, phone boots up before the process is completed. I'm completely stumped here.
Hi! Still have the problem? I faced the same two days ago when I tried to change the on on my SP. But finally I could save the Phone by searching a bit on the net. Pls tell me if matter is still on and I try to translate the steps to english.

Hey!
Sad to hear, but maybe (I hope) this method will help you. Basically what you will get is an original Xperia SP with 4.1 android as it came from the factory.
You will need:
1. Sony Mobile Flasher by Androxyde" version 0.9.18.6. Don't know if newer version came or better. You can find it here in forums. http://forum.xda-developers.com/showthread.php?t=2489955
2. The basic ROM "12.0.A.2.254".
The method that helped me:
SP turned off. Cable not connected.
Start Sony Mobile Flasher (Flashtool) , give administrator rights.
Top left cornet click on the bolt and choose flashmode, then in firmware selector you can find and select the downloaded ROMs and kernels. Choose the official 4.1 (12.0.A.2.254). Click falsh so it starts to proceed.
Then a windows appears called "wait for flashmode".
Now. Grab your turned off SP press volume down and connect the usb to pc. Keep holding volume down button till flashtool starts to upload the system. (Hopefully it will be fast enough, and phone will not turn on. For me it was)
After flashtool is finished you will see:
09:50:53 - INFO - Flashing finished.
09:50:53 - INFO - Please unplug and start your phone
09:50:53 - INFO - For flashtool, Unknown Sources and Debugging must be checked in phone settings
09:50:54 - INFO - Device connected in flash mode
Unplug and start the SP
If everything went as planned you have your phone back with stock 4.1 and 12.0.A.2.254 kernel.

Thanks a lot brother. At first it didn't work when I flashed it with the latest version of Flasher. Then I installed the exact version you mentioned (0.9.18.6) and phone didn't boot during the flashing and now it's back to normal with the default 4.1 stock.
Thanks a bunch, you're a life saver for me. :highfive:
