I read through many threads and have followed the official Sony bootloader unlocking instructions. I have requested and received the unlock code from Sony via email. I have downloaded the inf file and placed it in the correct folder in Android SDK (which I also updated). But I am cannot access fastboot mode, I hold down Vol + and plug in the USB cable but the device shows a red led and goes into charging mode. Also the PC never prompts me to install fastboot driver it simply loads the SP as Sony mass storage device (in device manager).
I have read that some people seem to think that the SIM lock affects the ability to access fastboot but this SP is SIM unlocked. Sony's official guide to unlocking the bootloader says I need to access fastboot mode to enter the unlock code but how can I unlock the bootloader if I can't get into fastboot mode?
hmmm... don't know really... i once entered fastboot mode by mistake, while trying to root stock rom. wasn't reading instructions and put device in a fsatboot mode instead of debugging... was on stock rom so don't know if custom rom would let me do that. should check myself... if anything i know it is possible to get me that blue light shining.
To enter fastboot mode in Xperia SP just power down the phone and hold down the volume up key while pluging your phone into your pc
If you need flashmode do the same thing but with the volume DOWN button held down.
I´ve got the same problem. I can´t enter in flashmode neither in fastboot mode. I´m on windows 8 32bits and I installed the .245 Deodexed ROM with a problem on root and without CWM. I don´t know what to do now, please help me.
As I explained in the first post, I understand how to access fastboot mode (and flash mode). I got root and backed up the TA partition, the stock apps (from 1.257) and backed up the stock ROM. Then, after I wasn't able to get into fastboot, I have installed CWM for LB and flashed a custom ROM based on 2.245. I am able to enter flash mode but not fastboot. As I said before, the phone is SIM unlocked but is acting like it came from a carrier, with locked bootloader and fastboot disabled. How can Sony disable fastboot? I don't get it. Any one want to take a guess how long I will have to wait until some clever dev finds an exploit?

Sorry for that i dont think that it is your computers fault because you enter fastboot (and flashmode) using your mobile phone NOT your PC
So i would roughly assume that this is a Rom bug or something in the flashing proccess went wrong.

Thanks for trying to help, but I understand that flashmode and fastboot are accessed using the phone. Actually the phone needs a piece of software like flashtool to keep it in flashmode otherwise it drops into charging mode. I didn't mention my computer so I don't know where you got that from.
As I explained, I am unable to access fastboot with stock ROM (1.257) and a custom ROM (based on 2.245) so it can't be a ROM bug or the flashing process having gone wrong.
if it's not too much of a trouble for you, go and flash .245 stock, than .257 stock kernel only. like you are trying to root it for the first time, complete rooting procedure, and than proceed on to installing CWM, but instead of connecting device in debugging mode to install CWM, try and see if you can put it in a fastboot. this was exactly the moment when i accidentally put mine SP in fastboot. of course, i'm not saying to go ahead and install anything if you score, but only to confirm if you can put your device into a fastboot mode since installing anything without CWM will likely soft brick your device.
Same problem here, i can't do anything using flashtool after flashed 2.245. I did with SUS, maybe is some flashtool issue.

It may be a flashtool problem you are right because 2 incidents with different Roms that both use flashtool to flash those roms.....
its pretty much self explenatory.

Interesting. Ok, I've read up on the process. So I use the various stock .ftf files and flashtool with the phone in flash mode? Bear in mind that kernel didn't allow fastboot when I used it with the stock .257 ROM the device came with. If I do it, I will nandroid backup first, of course, but I think I remember reading in one thread that someone managed to soft brick their XSP doing this very thing.

that's why you need to complete rooting procedure. root stock 1.257 kernel, than back to stock 2.245 with root preserved, and before you would install CWM try to put device in a fastboot mode, this assuming you still have a UB.

have you tried to boot into android, open a root terminal and type
exec reboot bootloader
that should bring you straight into fastboot

All that happens is that the terminal session ends and closes (not FC) the terminal app. Using the same command via adb just does a standard reboot.
i just placed my in a fastboot mode, no problems whatsoever. do you have drivers for the device installed? you will find these in flashtool installation folder.

Yes. The fastboot_with_android_usb_file.rar package specified on DooMLoRD's bootloader unlocking/relocking appears to have been removed and there are no new links in that thread. So, I found and installed the drivers included with the flashtool. But it seems to be the device that is the problem. It is acting like a carrier locked model. I am rapidly starting to believe that this one has a locked bootloader.

I said before, it's new firmware (maybe RU) with a Windows Flashtool issue. Today i did flash kernel to my SP using Linux client.
Same issues

Hi, I have some similar issues. I've also been flashing some stuff and whenever I try to go to fastboot it just boots into CWM. Very annoying to say the least. The dark blue light goes on when i hold down volume up and for a short moment I see the fastboot driver installing on my computer. But before it completes it's already in CWM.
Not sure what to do from here on wards, maybe some advice on which kernel to flash? I am pretty sure the latest kernel I flashed is the .254 root kernel from doomlord.
Ps. I really would like to flash CM when it becomes available as nightly :angel:
Thanks in advance!

I had already installed cm10.1 jb for my xperia ion.
Now i tried to install cm11 kitkat for my xperia ion.
Every thing is gone good.
But now got stuck up with a problem.
fast boot mode is active only for 5 seconds while connecting my xperia ion to System with flash tool.
help me to do the need ful.
Guide me to download compatible drivers and flash tool for fast booting process.
If you have UNLOCKABLE bootloader, then you dont have a FASTBOOT mode on your phone. Its just pure luck. some phones dont have it... kind of a sony crap... I also happen to be one of those LUCKY ppl. no unlock, so stuck with Stock kernel forever.
When you connect your phone to Flashtools in FLASHMODE...
See for a string BOOTLOADER: NOT_ROOTABLE.... it means you belong in the lucky group...
If it says rootable, then you're doing something wrong.
Pardon me if i read something incorrect. i skimmed through all the posts before posting.
I recently got a z3c and decided to try to get a slim rom on it.
I have done the following:
I unlocked the bootloader.
This was done successfully to the best of my knowledge
The next thing I did was flash a cwm image to by z3c using fastboot. The problem was that I flashed the z3 version on my z3c.
The device would boot but the screen would be blank.
Later I flashed the z3c boot loader named : Z3c_DooMLoRD_AdvStkKernel_v01_FW-105
After this the device goes in a boot loop. I am able to access CWM.
I have tried to root the phone as well as flash the slim rom in an attempt to fix it....
Wiping disk / cache doesn't help.
Also for some reason even though adb drivers are installed I cannot use it so I can't get the twrp install to work.
I have no idea what to do can someone please help?
Thanks,
stp
I have same issue....Phone is ib bootloop...i can still go to fastboot mode....
Anything can be done here????
Flash an factory image with flashtool then you will have original recovery. Then reinstall CWM, maybe smth went wrong.
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....
I managed to recover my phone. I don't think you need usb debugging for flash tool. What I did was turn the phone off (power and volume up seem to be the buttons that force shutdown and break the reboot loop).
flashtool will prompt you to connect when you flash the ftf file and you hold power up and volume down when you connect the usb cable. If you have issues flashing (it hanged on me on system.bin) try restarting your computer.
Resolution and Problem Exp
Right after flashing the device recovery through fastboot the USB cable is plugged and that seems to loop the boot loader, so you need to force shutdown while looping by pressing POWER + VOLUME UP, and after that unplug the USB cable. You will notice that on boot now the light is no longer red.

Hi everyone
Since I restarted my phone last night, my phone has been in a endless bootloop and I can't even enter recovery, without it rebooting again and going into the same endless bootloop again, around 2 seconds after showing the "Teamwin" logo.
I'm using ARHD, and if I remember correctly it's version 71.1. TWRP is "openrecovery-twrp-2.6.3.3-m7" and running ElementalX kernel.
I expect my partition is somehow corrupted, but I'm at a loss of ideas as to how I can recover my phone again. I would apreciate if I could somehow manage to make a backup of my data, but it that's totaly hopeless, I'm thinking of going for the ArtMOD ROM instead and starting fresh.
Is there a helpfull soul out there, that could maybe give me some insights as to what I can do from here? Thanks in advance!
I was hoping I could install a stock ROM and start from scratch again, but I somehow suspect having used a modified ROM has gotten me in trouble now and the ROM Upgrade utility sees this as a downgrade. I've not been able to find a newer ROM for the .401. series than "RUU_M7_UL_K44_SENSE55_MR_HTC_Europe_4.19.401.9_R_Radio_4A.23.3263.28_10.38r.1157.04L_release_353069_signed_2-1.exe". Although the updater believes I'm updating from 4.19.401.11 (the ARHD ROM).
I can get into FASTBOOT USB and the phone goes to the black HTC logo screen when trying to update, but quickly fails on the PC during the process at "Updating 1/5". When unplugging the USB cable the phone shows:"
RUU
Security fail!
Update Fail!
I've attached two screenshots, to better explain
Can some kind soul out there please help me getting a working phone again? What ROM I'll end up with doesn't really matter
Since you're using unlocked bootloader, why don't you try RUU to get back on Stock ROM.
Here is the collection of ROMS
Download your ROM.
from Windows Command prompt
adb reboot bootloader #
If it didn't work, Press and Hold Power button along with Volume down of your phone,
When you reach to bootloader, get into fastboot mode.
Now follow the following commands to restore the STOCK Rom. (make sure your downloaded ROM are in the same directory where you have fastboot.exe, abd, and abdwin.api etc)
1) fastboot erase cache
2) fastboot oem rebootRUU
3) fastboot flash zip RUU.zip (RUU.zip is of course your downloaded Stock ROM). If it says Failed, try again.
4) fastboot erase cache
5) fastboot reboot-bootloader
6) fastboot reboot
Good Luck
Hope that helps.
Thank you so much for helping out!
After several tries, tries and retries, I finally managed to get the phone back up and running with the stock ROM. I believe what finaly did the trick, was to use "fastboot oem lock" to get the stock ROM installed. From here, I'm now able to unlock it again and install a custom recovery (TWRP) and ROM (I went for ARTMOD). Thanks again!!!
I tried flashing back to MIUI 13, but my brain thinks that the flashing takes long, so I stopped it, restarted it and then the fastboot logo appears, means that I completely bricked the phone, I tried flashing to recovery, TWRP comes in and it won't load, any help on how to get it working again?

Flash again twrp via fastboot from PC.
Then go on with a recovery ROM via twrp....
Or flash complete stock fastboot image via PC
It's not a good idea to stop ROM flashing. If you can get to fastboot, you can flash again.
