Hello.
As same as in thread name.
Is it possible somehow to restore my phone to the original state with locked bootloader when USB in it is quite not working correctly?

Hello there, I posted a while ago because I wasn't able to update my HTC One nor connecting it to usb in any way.
Finally, now I was able to update it over OTA (wifi) and... well it still won't connect to USB.
Right now the phone is sitting at :
Android 5.0.2 Sense 6.0 software 7.19.771.21 and it's a HTC one 3
Strangely enough it's not sim locked cause I tried a vodafone sim earlier and it worked.
So, the main change here is that I was able to boot it into recovery mode but I wouldn't know what to do there.
Any advices on how to proceed to unlock bootloader, s-off and all that wonderfull stuff?
I reiterate that the phone WON'T connect in usb mode, not even in fastboot, looks like.
Thank you very much in advance

Already told you the last time that there is nothing useful in stock recovery, only factory reset.

Fix your usb port first. You must at least be able to use fastboot commands when in bootloader which requires usb connection.

I need help! I unlocked my bootloader and rooted my phone. But "Rooting stat Unknown"
Well now I know that I made a big mistake. I guess that sony made a hard brick in my phone. I am not sure if i will be able to unlock my bootloader again and I need information about it. I lost my DRM Keys and I can't take pictures, so It's driving me crazy.
Can I use a back up of DRM Keys from another locked Z3+?

You can't use drm keys from another phone. Plus you need root to backup your keys. And you cannot root z3+ without unlocking the bootloader first. Ive unlocked my bootloader. I have zero issues. Everything works great. What exactly did you do?

Not is my case. I rooted and later I touched "My xperia protection" and the phone didn't respond any more. Later I understood that it was a big mistake. I had to restore my phone with sony companion and now I don't have unlocked my phone and I can't root it , again. And also I lost all my DRM keys, so my camera is a disaster. I'm not sure about if I could restore the original state of the phone, locked but with the posiblity of unlocked again. My rooting status is Unknown.
I am completely new in the world of custom ROMs but experienced in the Linux world. I want to replace the original Android firmware of my mobile phone with LineageOS. Now I am looking for a way to be able to return to Android in case I am not satisfied with LineageOS or anything goes wrong. My idea is to plug the phone to my desktop computer (using Linux) like any other external device and mount the phone's filesystem so I can make a backup of it with the dd command. This way I could simply use that backup to overwrite LineageOS with the original Android. I have not found a howto for this procedure on the web, so I guess, my approach is not possible.
I found a few howtos that recommend ADB for this task, but the phone has to be rooted to apply ADB, so making a backup of my rooted phone would not let me return to the unrooted state, in which case the phone's warranty would be lost.
My question is: Is there an alternative way to completely backup my phone without rooting it? And if not, what would be the most simple but safe solution without depending on Windows-only software? Any advice pointing me to a solution is appreciated. Thank you.
Do you still have warranty on Xperia SP?!
1- You can Root and Unroot your phone again anytime.
2- You can Unlock and Relock your bootloader anytime.
3- The most important and the only thing you need to backup is the TA partition that has all DRM keys of your phone.
4- You have to Unlock your bootloader if you want to install Lineage OS ROM.
5- You have to backup DRM keys before unlocking your bootloader.
6- Here you are step bay step what you need to do before flashing Lineage OS ROM:
a- Root your phone using twolroot app from here
b- Backup DRM keys ( follow this guide for Linux ).
c- Download Flashtool version (0.9.18.6) for Linux from here.
d- Finally follow this old video tut to unlock your bootloader official way.
P.S: Read carefully the instructions in these links before doing anything, I am not responsible if you brick your devices.
Yes, I just bought a brand new SP with a valid warranty.
So, the only partition that is modified by the custom ROM is the TA partition?
I just noticed that my device does not allow me to unlock the bootloader. I have to find a way to achieve
Bootloader unlock allowed: Yes
Edit: Trying to boot into fastboot mode (holding volume up; connecting device to PC by USB) does not turn the LED to blue but to green, and in my PC's file manager the device does show up, but cannot be mounted
My phone is not SIM locked, so no network carrier, no contract involved. Bought it from a hardware online shop.

No, not only the TA partition but you can restore everything by re-flashing the stock rom except the DRM keys must be restored from backup.

if you have "Bootloader unlock allowed: No" then I don't think you'll be able to flash LOs Rom.. And I don't know if there's any way to make it "yes".. Sorry [emoji120]
But there's some old ROMs for locked bootloader devices here on xda just search for it if you want kitkat or lollipop or even stock based ROM.

So, these ROMs can be flashed without fastboot? How is that possible?
I managed to unbrick my Iphone now I lost the identification by fingerprint, and I do not know how to recover a restore by hisuite is possible, is it possible to reblock the bootloader?
I need to send in my Xperia 10 dual sim for repair (probably need new battery), it's still on warranty.
Now I had lineageOS on it, and hoped to resolve the battery charging problems by re-flashing the original firmware. I don't have a Winodws computer, so I used XperiFirm and Newflasher on Linux to do that. Everything looks original now, But of course I still have the "your device can't be checked for corruption" effin message popping up, and I don't know if the retailer will service my phone for free if they can see I had the bootloader unlocked.
Now I read that re-locking the bootlaoder will
1) also reset the whole thing to factory settings, delete all data.
2) break the camera?
1.) Is not a problem, they want you to do that before service anyways, and I backed everything up.
2.) Is a problem, because they might yet deduce that I unlocked the bootloader, or give me some other trouble.
However I also saw it hinted in this forum that re-locking the bootloader should be fine if it is done on the original firmware, which would be the case.
...=> If I re -lock, do you think I'll be safe sending it back, regarding signs of the BL being previously unlocked?
