[Q] Boot loop, no usb debug, no cmw - Xperia SP Q&A, Help & Troubleshooting

Hi all! like most I have joined with a problem
I Have an xperia SP-C5303
I successfully rooted the device with the Towelroot app, Then used the sony mobile flasher by Androxyde to flash cyanogenmod 10.2 onto my phone. This was all working fine.
I used CMW to install an update downloaded through cyanogenmod. When I rebooted the device it was stuck in a bootloop. The device connects top the computer in flash mode, but will not accept a flash because somehow "USB Debugging" is not enabled. It was obviously enabled before because I had already flashed the device.
ADB drivers are installed but to be honest Im a bit lost now. Does anyone have any ideas how to turn on usb debugging so that I can flash my phone again?
Korbey
I can connect to sony mobile flasher in flash mode but flashing fails at the end with the program saying "For flashtool, Unknown Sources and Debugging must be checked in phone settings" how can I activate these when in a boot loop?

I would like to know if your Xperia SP has its bootloader unlocked?
The error most likely appear because you have no drivers for Xperia SP. Yes you might said that you installed it already but let's try again. Navigate to the Flashtool installation directory, which is C:\Flashtool by default. Then go into drivers folder and run the installer therein. Please tick fastboot drivers and flashmode drivers. Scroll down a bit and find Common drivers for Viskan board. Tick that as well and continue the driver installation.
After everything is completed. Close Flashtool and open in again (in case you've disabled UAC, please run Flashtool as an administrator). Then retry to flash a stock ROM's .ftf file.

SEMC Flash Issue only when flashing

My PC and phone setup works as expected but gives error when booting in flash mode. PC Companion and other tools (Flashtools) can recognize device but holding back button while connecting to usb (when it is already OFF) makes "Device driver failed" error and makes yellow exclamation mark on device manager for "SEMC FLASH ...."
Win7 XP 64 Bit
Sony Experia X8
Latest PC Companion app.
What I tried:
- Disabled antivirus from beginning.
- Gordon's Gate Driver "ggsetup-2.2.0.10" and "ggsetup-2.2.0.11".
- Flashtools/Drivers/ "X8 ADB Driver"
- Another Win7 64 Bit Computer with disabled antivirus
It fails only when detecting the sim lock type with S1Tool. My phone led turns green as expected. I follow this guide http://forum.xda-developers.com/showthread.php?t=1693308
Now I get "Access Denied" error
I' ve copied "X8 ADB drivers" to somewhere and tried to update drivers by "Update Drivers" on device manager by choosing X8 ADB Drivers.
And now "S1 Tool" freezes or says
PLEASE ATTACH TURNED OFF PHONE NOW
llbug:[\\?\USB#VID_0FCE&PID_ADDE#5&30124de0&0&5#{a5dcbf10-6530-11d2-901f-00c04fb951ed}] open error: "Access is denied"

I tried when AV is Off with no luck
I will try flashing in the safe mode as suggested on another post.
How to get X8 ADB Driver: When installing drivers from flashtool it will temporarily copy the driver files to "C:\Users\...\AppData\Local\..." (ass seen on the install screen) . Copy the files from there before installation complete.
SuperOneClick
SuperOneClick was the correct way to unlock my bootloader. But know I can't install custom kernel. Because this time flashtool can't recognize my device in flash screen.
I will try with Flashtool 6.9.1 instead of 0.9

I recomend you to install flashtool and unlock the bootloader with it ("BLU") it is easier and faster,
To install the usb drivers I also got problems, do one thing this is how I got it to work.
connect the phone with fastboot button pressed, the PC will ask for drivers and will open the "new hardware assistant" do not allow it to install them automatically, do it manually and sellect the folder where you downloaded the drivers, in some point the phone will power off as it doesn´t get any response from PC (this is why it was not installing them properly in may case) just before pressing ok connect again in fastboot (and close the new prompt of "new hardware assistant" let the old one install the drivers and will do it properly.
Still have a problem with drivrer installation
I've try to install driver from.exefile in C:/flashtool/drivers

You need to install the drivers after disabling driver signature enforcement in Windows 8. If I remember correctly, I got it working by just installing the Fastboot and TX drivers from Flashtool. I did it about a year ago, so I'm not sure if Flashtool can correctly unlock bootloader already (it couldn't when I did it), so I would suggest just using fastboot.exe the way it is described in the official Sony page.
By the way: are you sure your bootloader can be unlocked?

[Q] Accidentally formatted /system on unlocked BL Xperia T: now it won't boot.

Hi guys,
I accidentally formatted /system on my T with UB.
Now it won't start (it says "Sony", then nothing happens). It now has no recovery and if I connect the phone in fastboot or flashmode, the usual PC I use to flash says me that "Sony ADB interface" is connected, but it can't find any driver.
What can I do now?
Thanks in advance for the reply.

If it says "Sony ADB interface" when you connect it, then you don't need a driver, it's already installed (you can confirm this if you open Device Manager in Windows and check if it's listed as an "ADB interface" and there are no "Unknown Devices" and/or devices named in relation to your phone that have a yellow exclamation mark.
Just flash a stock FTF, or download one of the kernels for T that have a recovery, and flash any ROM you like.
First of all, thanks for the reply.
The strange thing about this time brick is that my pc doesn't recognize the phone. Other times, infact, I used it with the same phone to relive the Xperia T, after strange things happened.
Instead, this time the phone is recognized as "Sony ADB interface" and the pc says there's no driver in it. And it can't find in the system (I'm using an old laptop with Windows XP on it).
That's the reason why the system (and Flashtool, too: it says, in red, that I need to install the drivers for my phone) doesn't recognize the phone.
Now I'm trying the T into another Windows XP old laptop system...I hope it works (and I hope USB 1.1 will be fine, too...).
EDIT: this "new" pc see my phone, connected in fastboot mode, as "SEMC Flash Device" and it is installing the drivers. I've already installed fastboot/flashmode drivers from Flashtool Drivers folder.
RE-EDIT: PC can see the Xperia T, but Flashtool always says that it is connected in "flash mode", even if I connect it in fastboot mode. What should I do, now?
RE-RE-EDIT: The phone is recognized only in flashmode, even if I installed all the drivers. I'm trying to flash .141 and it seems to work. Let's see what happens.

Ok, well, no idea about it being stuck in flash mode, but, isn't that exactly what you want? To flash a stock FTF you need to be in flash mode. As a matter of fact, you can even flash only the kernel of an FTF in flash mode, it wouldn't have a recovery, since it would be a stock kernel, but at least you could get a working kernel, if that were the issue, which it is not.
What are you doing to put your phone into fastboot mode?
I wanted to use fastboot to flash a kernel with recovery and then flash the backup of my old ROM.
However, it doesn't worked. Only flashmode worked. So I flashed (really slowly, because of USB 1.1 ports of this old IBM laptop!) .141 and now the phone is living again.
Dunno why fastboot didn't work. Maybe because there wasn't any firmware on?

No because the whole point of fastboot mode is to be able to flash firmware related files. Fastboot mode, just as Flash mode, starts before the Android OS starts. If they depended on there being an OS installed it would defeat the whole point.
So I really dunno why it didn't work. Later I'll try to see if now fastboot is working again.

When you don't have a ROM installed,stock kernels recovery won't work. Flash CM 11s Kernel, you'll have recovery then restore you're backup

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.....

[HELP] Unable to flash firmware on Xperia SP C5303 using flashtool

So, the problem is that Xperia SP was working nice on Carbon 4.4.4 but then I flashed a kernel with bad WiFi module. That had a builtin TWRP (I previously had CWM and backed up everything using CWM)... then I did a really bad thing. I renamed boot.img from CWM backup to boot.emmc.win (TWRP compatible) which subsequently flashed CWM and old kernel. I forgot to restore my SYSTEM as some kernel parts are there (I knew it wouldn't work but I had plan to restore it via CWM)
Then I rebooted into recovery but it didn't reboot. Instead it showed me Sony logo and red LED. Then black screen and repeats same. I learnt how to hard reboot and it did no good. I have unlocked bootloader and I'm trying the flashtool but it won't recognize my phone (I have installed C:\Flashtool\drivers\*) on Windows 10 but it didn't do any good either.. Now when I reboot into fastboot mode it shows me blue LED but isn't detected by flashtool;
Same is with the Flash Mode. Green LED but no connection. On the notifs panel on PC It shows that device not recognized. On Device manager it shows: Unknown USB device (Device descriptor request failed)
I wanna install the drivers but they're already done. I reinstalled them twice just for surety's sake... Any suggestions to install drivers and flash the firmware? I don't know much about Sony as this is not mine, this is a free device that no one uses in my family. I own jfltexx
Edit: Whatever mode I put it in it bumps (reboots) out
Try letting the phone in flash mode and wait a bit till windows install driver automatically, or go to device manager and update unknown device driver, if this don't works, i don't know what more to do
