[Q] Xperia T, cannot access phone through USB - Sony Xperia T, TL, TX, V

Hi guys,
I got an unlocked, rooted Xperia T with CyanogenMod 12 and the Cyanogen recovery on it. Because i could not install any new roms through this recovery I tried some other thing and did something quite stupid: I think i deleted some USB-OTG software from my phone. Now i cannot access recovery anymore, cannot get my phone to factory default and i'm not able to link my phone to my computer, the computer only responds in fastboot. Any suggestions how i could get my phone working properly again.
Thanks!

[Q] HELP: Stuck in bootloader or no USB

Hi All,
from one moment to another my X1 decided to boot into bootloader mode.
The strange thing is however, that when I connect it to the USB of my PC and reset the X1, it boots normally. Well, almost normal as the USB doesn't seem to be working.
I flashed the rom to APP-SW_X1_GENERIC_UK_1213-6450_R3AA010__KOVS using the SDCard and that worked without a problem. But still the X1 boots into bootloader mode (except when connected to the PC).
I tried a hardreset, pressed the volume down button several times (to make sure it isn't stuck), tried to use MTTY (but that doesn't show a prompt), but nothing seems to help.
Is there anyone who can help me with this, because I'm out of ideas....
Update:
I managed to boot the OS (USB connected) and install HSPL using Xperia-SSPL-Manual. This succeeded and I now have SPL-0.78.OliNext. I flashed the phone to a new ROM (826x_KOVSKY_29017_2021), and that succeeded as well. It didn't solve my problem however. I still get the bootloader screen when I start the phone and can only start the OS by starting with USB connected...
Update2:
Yesterday evening I took the whole phone apart to make sure no buttons are/were stuck. Didn't find anything, put it back together and it still boots into bootloader.
I also managed to get a connection to the phone using NueTTY. I executed command Set 14 0, restarted the phone...and still it boots into bootloader.
If there is any one who knows of something that I haven't tried yet, PLEASE let me know....
same problem,,if there's a way to flash recovery from sd card in fastboot mode,,that'd be great

Flashing the ROM is no problem, I can put every ROM on it that I like. But even after flashing the ROM the phone still starts in bootloader....
You can try to go into the bootloader on ur pc and use recovery.bat with fastboot.

hi, I'm kind of having the same issue as you do..can you please be of help and tell me how did you manage to HSPL it to 0.78.OliNex?
Correct me If I am wrong, but you must copy Xpera_SSPL_Manual. exe on X1, run it from file explorer and then run X1_HardSPL.exe on your PC, whlie X1 is connected via usb (although mine also doesn't recognize the X1) ?
i would really apreciate it... thnx
i have the same problem guys, did anyone of you found any solution for this?

Have you tried to do a task29 with KovskyAdvancedRUU?

Problem install CM on Xperia SP

Hello guys, this is my first post, I am writing to ask for any kind of help for a problem I'm having with an Xperia SP, I describe everything.
The mobile stock has started to have problems with the SIM, turned off all the time, how to Fix PC Companion is not served at all. I wanted to try to install the CM to see if the problem disappeared, but since I could not access the phone I could not turn on USB debugging. Following the guide to install the CM11 get to the point where I access the Recovery where I have to choose how to transfer the MOD on the phone, but the problem comes here, after reboot the phone is no longer seen, the reason is for USB debugging disabled? Or for other reasons? Can I get around this?
I tried to load the MOD on the SD Card and start it from Recovery but the experiment failed. Tell me something wrong, how do I proceed?
Thanks in advance.

Is this a hard brick you're trying to explain? You can try to reflash stock FTF by using Flashtool. Please refer to this thread and report your findings here

[Q] Brick flashed with m8 rom? - Cannot fastboot/adb and TWRP wont mount my USB

Hey Guys,
you are my last resort of hope as i have given up to fix this problem by myself.
I have an HTC One M7 that i have done a bigger repair on (=new camera, battery, display, backcover). Phone had worked fine so no hardware issues.
After that i decided to set up a new rom to also have a 'clean' system, but after i wiped via TWRP as usual (only data and sdcard...) i accidentally flash an M8 ROM which i had stored on the internal SD card after the wipe.
Of course the installation failed and i was not able to mount my USB-OTG or connect the device by fastboot-USB or ADB. Windows only lists my phone as "Unknown Device".
I am still able to acces TWRP and bootloader, but i cant connect anything to the device to set up a new rom.
Drivers are not the problem in this case, as the HTC One of my friend will enter fastboot-USB and will be found by fastboot just fine. Mine will always show just "Fastboot" and wont be recognized.
After that i have tried several 'fixes' found in other threads, but i think i messed up even harder, as now windows wont recognize anything at all. Also have no luck with linux.
Herei is my data:
*HTC One m7 Unlocked + S-OFF
*CID-02__102
*HBOOT-1.44.0000
*RADIO-4A.14.3250.13 *OpenDSP-v26.120.274.0202
*TWRP 2.8.5.0
*Rom was the lastest Venom Rom
Any idea on how to solve this problem? I run out of ideas and think i am stuck with a bricked phone...
Would be so easy if TWRP would just let me boot my USB
Thanks in advance to everyone willing to give me a hint!
Greetings to you all!
Dont you have a nandroid backup?

My pc don't recongnize the phone.

GIONEE ELIFE S5.1 / Kazam Tornado 348 / Allview X2 Soul mini etc.
Hello Guys! . I've got an issue on my hands, and I'm not really sure how can I solve it. I installed a ROM, through TWRP recovery. After flashing, I tried to access the recovery, but the the phone started to bootloop, and sometimes it showed a greenish welcome screen. After a few bootloops, the phone started normally, entering the system. So, no recovery on it. Right now, after I tried to access the recovery a few times, the phone is blocked on bootloop . No access to files, no access to system, and no access to recovery also. Can you please advise what can I do furthermore?
Also, very important to mention is that the computer doesn;t seem to see the phone, I tried to another PC, the same thing. It says (in both computer cases) " USB device not recognised".
Is there any way to force somehow fastboot mode on the phone? ...
I really need some helping ideas, since I'm out....

Softbrick with USB Debugging disabled HELP!

Hi to all!
I have a Cherry Mobile One G1, pure stock (Android N, not rooted, no recovery and USB Debugging DISABLED), been with me for almost 2 years bought brand new. What happened was I was going to download a movie then suddenly the phone restarted and its stuck on bootloop. The only thing I can do with it is boot it to fastboot. It can be detected by my pc's device manager as Android Bootloader Interface but ADB terminal cant seem to detect it. Is there anything I can do to revive it? If there is, can any genius mind help me out?
My dilemma now is trying to turn USB debugging via fastboot which is not possible since adb could not even detect my device. If only I can have it enabled, I would know how to fix the rest.
Any help would be very much appreciated. Thank you and God Bless!
This happened to me before. factory reset via stock recovery fixed it. If you can't boot to recovery try removing the sd card first. It will take a while to reset, don't take the battery off while it does and make sure it's charged.
