I'm new to this business so I might not know everything.
I wanted to install Lolipop on my xperia sp using cyanogenmod 12.1. I rooted it with towelroot, got superuser and installed Rashr to get a recovery mode program. It asked me to make a back up first, so I did. Then I went on an selected TWPR img and it flashed a partition but didn't reboot as it asked me to, I then realized I missed some steps in the installation process.
So I went on and used the backup Rashr made and it also cleaned a partition. Then I rebooted. Since then, it's stuck in bootloop, the screen flashes on and off just pure black and never reaches the logo just solid black. I tried turning it off from the back, going into recovery mode but I couldn't(I held the buttons for at least 2 min and it wouldn't work), it would just light the blue led for a little and then resume to the loop.
PC, Sony companion doesn't recognize it. It only sees it when I try to go into recovery mode(power + volume up) while it is plugged in and appears in device manager as "S1boot Fastboot", I left it for a good 10 min to install the driver, but it wouldn't.
I don't have bootloader unlocked. Right now I left it on so it could drain the battery, but it should take a long time for that to happen. Please help me!!
FIXED
After looking for other fixes, I found this guide and it worked just great.
I've a problem:
My phone is unlocked, UBL, with original 205 firmware. Sometimes it's turned off, the boot was problem: few bootloot before load the system. I installed twrp and cwm, but reinstall twrp, from twrp, and it's the problem. If I power on in flash mode, the phone exit from flash mode after 43 sec. and light is red. After 63 sec go to back to flash mode. I don't flash my phone. Help please! Sorry my english.

Hi, I sorry to bother anyone, but I need help because my phone is not responding and I don't know what to do.
C6603, rooted, dual recovery installed, bootloader unlocked (I think)
So here's what happened. I very successfully installed the existenz ultimate rom on my phone. It was a wonderful rom and everything was going well. However, I accidentally dropped my phone and needed to send it for repair. Before sending it to the shop, I decided to do a factory reset using the option in recovery mode.
When I got the phone back from the repair shop, I wanted to install the same rom. What I did was download the rom installer and then install the zip file using the recovery mode. I went through the AROMA installer and everything, So I thought everything was going fine. When the phone rebooted, it showed the SONY logo, followed by a permanent black screen. The screen is on, it is just black.
I scoured the xda forums and I tried several things, to no avail:
I cannot enter recovery mode.
My PC cannot recognize my phone.
Flashtool cannot recognize the phone. My phone can't seem to enter flashmode, either.
I tried holding the power button and the vol. up button, and the phone does indeed restart (no vibrations), showing the SONY logo, and then I'm stuck with the black screen again.
I hope somebody can help me!
EDIT: I managed to somehow get flashmode working, so I think my phone is fine now! What a false alarm! In case this ever happens to anyone, what I did was to unplug the phone from any source of charging, then proceed to hold on the power button and vol. up button for REALLY long, I think almost 20 seconds. This managed to switch my phone off (it would keep restarting if I didn't hold in down long enough).
download stock firmware and open flashtool & ready to flash,dont connect until it say.connect your usb cable to ur phone,then reboot ur phone when display goes to black connect ur phone to pc whith pressing vol down ,then flash tool detect ur phone and it flash,sorry foe my bad english
So I was about to move from CrystalPA back to the latest FXP CM11 build, i backed things up, went into clockworkmod, did all the needed wipes and was about to flash when I realized I downloaded the honami version instead. So I was downloading the right version but the download took about an hour, i left my phone in CWM while the download was going and by the time it was finished, my phone died. Now I left it on charge overnight so it should have been fully charged but I dont think it did much charging. I got to being able to switch it on and seeing the sony logo but because I'd already done all the wipes (system, data, cache, dalvik) it couldnt boot. I then used the button on the back to switch off and tried to enter recovery by holding vol + when i switched on, then i tried vol -, then i tried the camera button. Nothing happened, just sony logo then a black screen. After a few attempts, the phone is now flashing red when I try to turn it on, and when I plug it into charge, its just a constant red light (brighter than normal charge light).
Does anyone have any suggestions on how to revive my phone?
Thanks
Did you try to push vol -/+ buttons a few times instead of holding them?

Click to expand...
Click to collapse
I didnt, and i cant now because its just doing red lights only, Ive managed to get it into flashmode so im going to just restore it back to full factory with flashtool and just start again. Hope it works, the flashtool log is saying "device: unknown"
Edit: So the flashing worked, got back to 254 firmware with the old FTF file I still had, I then had to make my own 205 firmware FTF with XperiaFirm and Flashtool, I then flashed the new 205 firmware because Sony PC Companion wouldn't update my phone as its unlocked (i think?). Now all I have to do is install CWM, root and then get CM reinstalled.
I warn everyone - do not leave your phone in recovery when its running low on battery! youll have to start from square 1 if it dies!
Don't need to reflash ftf, just extract boot.img from cm zip and flash on flashtool, then just enter recovery and install cm
Use Lucas's method in the future.
Flashing a recovery-ready kernel is easier you know Anyhow, glad to know your SP worked again.
edit: fixed it, just flashed a stock FTF, i'll dot the whole process again later on and hope this time it works out
You can close teh thread (i've tried to delete it but can't find the option)
I've just checked that I can boot my phone and recovery works. But for instance when i try to put service mode it gives an error with IMEI
edit: i've booted to the other recovery (using volume up) and installed the pre-rooted FW again. Shut down and tried again the flashmode process but still no luck, red and quick green light. After booting the phone, it seems to work basically, but wifi not working, it doesn't turn on.
What should the next step be?
The computer does not recognize the phone when my connect it to the USB port, not even charge. The only thing that happens is a flash of red light then green light. Same thing if phone is shut down when i connect the usb cable, red flash, then sony screen appears, then green light, and finally it vibrates two times before showing the level of battery, but without actually charging it.
Anf if i try a Vol Down+Power when in standby and connect with usb cable, it shows a quick red then green flash, and then nothing.
Ok i fixed that problem apparently the USB cable decided to stop working...
Now i have another problem as I decided to install the deodexed ROM and now my phone gets stuck at the sony screen and i can't even boot to recovery.
What i did to install:
Boot to recovery using Volume Up (PhilZ)
Prepare to install new rom (which formats Data, cache, etc)
Install ROM form SDcard1
Everything went fine but at the end it says "root lost or something" I put yes, then rebooted to system, and got stuck on sony screen....
What did i do wrong and how to fix it??
Thanks for the help!
Hey there,
I followed the guide on XDA to root my Xperia SP with the Towelroot app. The guide is here:
http://forum.xda-developers.com/showthread.php?t=2783885
I then rebooted my phone into recovery, and flashed the latest build.
I rebooted the phone and downloaded the latest Cynagonenmod 12.1 nightly build for the Xperia SP. Once downloaded I wiped my phone and installed the ROM using the TWRP recovery that I'd installed before. At that point I powered off the phone whilst I downloaded the Gapps package on my PC.
When I returned to my phone to try and turn it on nothing happens. It won't turn on or even load the splash screen when I press the power button.
When I hold the power button , the phone vibrates and nothing more! The reset button on the back of the phone does nothing either unless the phone is plugged into a PC. Even then, the phone vibrates 3 times but still won't turn on properly.
I have gone through the Flashroot tutorials over the last 3 hours trying to solve this problem but I've had no success.
I have found that if I hold the volume key down and connect the phone to the PC then the green light appears on the bottom bar of the phone for a period of about 40 seconds before turning off again. It then turns back on and repeats the process.
I am unsure what to do next. Sorry for the long post.
Any help is much appreciated!!
Flashtool progresss
Sorry for the bump but if this helps anyone that could potentially help me. Here is what happens when I try to use Flashtools to flash a stock ROM onto the Xperia SP.
EDIT: Don't worry I solved the problem. I instead used the PC Companion tool to recover my phone and it worked a charm!
I realised the mistake I made. I tried to install Cyanogen Mod 12.1 without an unlocked bootloader which is what likely caused the brick.
I really need help.
I've got my phone bricked and I can't even boot to flash mode or to recovery mode.
The last thing I've done is boot to twrp and clear data because I am going to change rom. But there is a certain error that pops up. and forgot what was it. After that, I try to flash the rom. But the same error pops up. If I remember correctly. e:ex4ts is not found? Something like that? And now. When I turn on my phone. The xperia logo still pops up. Then after that its only black screen. I tried going to recovery (power + Vol up + vol down) and also tried flash mode but nothing really happens. Its like not being detected. And when I try to charge it. The xperia logo pops up and black screen appears. The charging icon/animation is not popping up. Is there anyway to fix this? Please help. Any help would be much appreciated. Thank you.
Your phone is now bricked and won't boot into recovery.You need to flash stock rom via flashtool to recover your phone.Is that your phone's bootloader Lock?Unable to boot into recovery always happen in locked bootloader phone.
Use Flashtool to flash stock rom. But be careful to connect phone only when prompted. It should boot after that, then you can root phone again and try to install recovery again.
I have unlocked bootloader already. I think there is something wrong with the phone. I can't boot to flash mode and recovery mode. The screen continues to go black light. I've tried for more than 20 times already. But still. I can't go to flash mode. Can I go to flash mode by only connecting my phone to my pc?

use recovery img to flash via flashtool.you'll get your recovery back
Thank you so much for answering my query. I figured it out before reading this. Yes, I forgot how to use flashtool. I forgot how to boot into flash mode. I used the method in Samsung devices (All buttons must be pressed) which technically my mistake. Thanks again.
