Hi! This is my first post in the xda, and I've learnt alot of things (from rooting, unlocking, to adb) in the forum and I really appreciated it.
But then I've ran into some problem trying to unroot my device(You know, 5.0.2). At first I tried the "Universal Unroot" apps on Playstore, which claimed to unroot a device in one key, but doesn't seem to work. Then I tried SuperSU, which told me that my device isn't rooted, and told me to press a key to root it, so I played along. Then after reboot I tried to unroot using SuperSU but it took forever (20mins min) and I cancelled it by closing the apps. Then I tried using the "Repair using PC Companion" method and it said there's a problem with my connection and repairing can't be completed. So I tried to turn on my device then and, boot loop happened and I can't even enter recovery mode. The flash key still works though because I tried it again with the PC Companion but it just tells me that there's a problem with my connection.
I have an unlocked C6903 ;boot loop can be stopped by using the hard reset button or power button + volume up key; it's chargable with green LED light with the usual charging screen; no red LED of death; I have TWRP installed;
Please help me Xperts!!!
EDIT: I've succeeded in repairing/updating with 4.4.4 and now I'm stuck at bootscreen where 2 wavy thing waving

I rooted my Xperia Z (via http://forum.xda-developers.com/showthread.php?t=2186368) and it was working perfectly fine for quite some time... now it gets stuck in a bootloop every time I try and restart it.
So, the information that I have:
The device has a locked bootloader, I rooted it using DooMLoRD's thread, linked above.
It worked for a while. I installed Titanium Backup.
When I turn the device on, it gets stuck in a bootloop.
When I plug it into my computer and hold the vol +, I get a blue LED and nothing else.
When I plug it into my computer and hold the vol -, it flashes red then green very quickly, then the LED turns off.
Nothing happens if I tap the vol+ during boot.
I'm trying to piece things together from other threads on the forum, but to no avail.
I found a thread started by someone with a similar problem (http://forum.xda-developers.com/showthread.php?p=38669779), but he doesn't say how he eventually fixed it.
Could anyone give me some advice or step-by-step guidance on how I should proceed?
Thanks!
I am having the same Issue:
Locked bootloader (Three UK network - bootloader unlock allowed:NO)
Rooted, Then installed "recovery for locked bootloaders"
Tried to flash rom, gave error code 7 for the zip, flash failed.
Now bootlooping, Cant get green LED with volume DOWN, But can get blue LED....
I think the blue LED is for fastboot, and apparently that only works with unlocked bootloaders.... Is that correct ?

Never mind, now solved
It seemed, that when stuck on the Sony logo loop, If I held volume UP and power button (to force a restart) it would vibrate once, then immediately switch my finger to the volume down key (AND HOLD) the flashtool program would recognize the device in flash mode
(even though there was no green LED on the device indicating it was in this mode, IN FACT, the phone just looked like it was completely dead whilst i flashed it with Stock unbranded firmware... but it worked)
Moral of the story .. persevere !
Hope you sort your issue too

You can recover using flash tool. Use my guide to get your ftf if you don't have one and then you can reflash it in fast tool
Sent from my C6603 using xda premium
I finally found solution! Bootloader on my phone isn't nearly same as usual one, no white screen, just a few lines which designate modes. 4 are present:
-normal boot
-fastboot
-recovery
-UART boot
I accessed it by pressing and holding power button and volume up button at the same time during device boot.
I hope someone with a same problem will find this helpful!
I managed to boot to system but I still can't get in bootloader. No combos and neither adb works.
I got my HTC One from second hand several days ago and I instantly noticed that something wasn't right. System was naked, no bloatware, no usual settings, no proper identification so I decided to install custom rom. I tried to boot to bootloader which I wanted to unlock(I guessed it's locked 'cause recovery is stock) with key combos, adb but it simply didn't boot to bootloader nor it rebooted or sometimes it went to factory mode which is on chinese. Again, I tried to find which version of phone I own but I can't figure it out. Moreover, I downloaded and put stock rom on virtual sd card and booted to recovery, opened menu with power button and selected to install package from zip just like it's said in thread but it outputted 'Install /sdcard...' and nothing else for past couple hours. Recovery isn't frozen, It shows\hides menu when power button is pressed. I tried to force shut down it by holding only\in combination with power button\volume buttons but nothing happens. I don't know what else to do...
Any help would be appreciated.
EDIT: It eventually discharged but when I turn it on with charger in it I get blinking white screen on every 3 seconds and when long pressing power button phone just vibrates. In combination with volume down it keeps blinking on every 3 secs and with volume up on every 5 seconds. To me, it looks like it's trying to boot but bootloader can't find anything installed. Computer is recognizing usb device on the moments when I connect it with usb just like when device is rebooting.

You have a fake phone
I agree, you've probably got a counterfeit One, but you can't flash custom roms from stock recovery anyway.
Firstly, thank you for any answer. How do you mean 'fake'?! I got it in original box and IMEI's are same(on box and device) What can I do with it then?
I tried to flash stock rom designed for stock recovery, at least that's how I understood.
MIDN07100 (Europe, a guy from which I got device claimed that it's from England so this should fit)
IMEI:354436053103493(same on device and on box, checked with IMEI checker it appears as valid HTC One device)
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
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'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.
