Problem with FastBoot

Hello, i have just registered to the forums, but i already follow xda for a long time. So here is my problem, i have already installed "ICS JJ's Hybrid Rom" on my Xperia Arc S without trouble at all, but now that i want to try a new rom i'm facing a big problem with fastboot.. I have tried to go FastBoot pressing Menu/Back button and plug in the phone, i tried to reboot in fastboot by X-Parts/Rom Manager and so on, but no luck untill now, and i dont know what is the problem since i don't even get blue light when i try to do it.
Yes i have installed flashtool drivers for the phone, basically green light appears instead of blue, the phone goes on black screen and after 5-10 seconds it disconnects.
I don't know if you guys need more information or not but i think im doing everything correctly, because i have tried countless guides and videos.
I would really appreciate some help if possible, thanks.

Have you actually unlocked your bootloader?

as i said, i have [ICS]JJ's Hybrid Rom on my Xperia Arc right now, so yes i had to unlock bootloader to install it.

JJ's hybrid works on locked bootloaders too. Have you flashed any custom kernel

If you get green light, you are turning your phone into flashmode and not fastboot. Hold down Menu button and then connect the cable.

I know that i enter fastboot with holding menu button but it just doesnt work, the only way it works is with Emma (Sony FlashTools) and it appears green light as well when i do it.

[Q] Phone in not starting after installing custom rom

I have installed CyanogenMod 11 custom rom to my Xperia Arc S. After flashing boot.img through flashtool, device got shutdown. Till now everything was fine. But after this the tutorial said to start the phone and after the phone vibrates, start pressing the volume down button. I did the same. But after vibration, phone is not showing anything. It shows dim light on screen but its not showing either the logo nor its starting. The LED light on side turns to purple but nothing happens after that. I did this with every button but its not starting. Pls halp me out....
Thanks...

Tell more about this. How did you do it, what happened, what buttons did you press etc etc.

Yes. I have installed kernel for it via flashtool. Initially after doing this it was not going to recovery mode and also it was not getting connected to flashtool. But now it is getting connected to flashtool in fastboot mode. So tried to flashing with 10.2 version, it showing finished but again the same problem. Its not going to recovery mod.

as in, HOW did you flash the kernel exactly. Dont just say you used flashtool, how did you use it? What combination did you use to get into fastboot? Any errors in flashtool? How did you boot into recovery (I.e. which keys did you press) and does the LX kernel logo even appear on boot?

First check does that kernel has built in recovery...If nothing works,to get your phobe to work flash stock .ftf file with flashtool.
Do you have unlocked bootloader?
And try one more thing,when you turn on the phone start pressing volume down (-).)!

I think i have the same problem as OP.
I decided to try out LegacyXperia CM11 and installed it yesterday. It went well, but it is still kinda buggy so i decided to go back to besttt's Slim Bean. I copied rom files on SD card and went to flash kernel (darkanzuEOL). I flashed it through Flashtool like every other time and it went without errors so i proceeded to boot into recovery so i can flash the rom. This is where everything stopped working normally. After i power on the phone and press voldown to enter cwm it just gets stuck on cwm loading screen. If i dont try to get into recovery it just bootloops. I tried several kernels i have on my HDD and always the same result.
I'm downloading stock img to flash and see if that will help. will let you know what happens.
EDIT:
Stock img worked, now i'm back on slim. Only other thing i changed ( which i think is the cause) is i used original sony usb cabel instead of my Nexus 7's i used originaly

This phone doesnt have any Volume +/- power button trick. It ONLY has the yellow reset button. Its a pain in the A*S!
Try a few things first.
1) When you hold down the yellow reset button, are you ONLY holding it down for a few seconds, and it vibrates ONCE?
Have you tried holding it down for 10 seconds, until it vibrates TWICE, indicating it has powered off completely, and THEN try connecting it?
2) If step 1 got your phone to power off completely try:
-Connecting your phone to your PC via USB with the volume DOWN button held and see if you get a GREEN L.E.D. If you do you have
successfully entered flash mode, in which case you can simply flash an FTF file with flashtool.
-Connecting your phone to your PC via USB with the volume UP button held and see if you get a BLUE L.E.D. If you do you have
successfully entered fastboot. From here, as long as you have ADB and your devices drivers installed on your computer, you can flash
a boot.img or "Kernel" with a fastboot command in a command window (fastboot flash boot boot.img). The easiest way to get a kernel or
boot.img with a baked in recovery is to download the latest Cyanogenmod, unzip and extract the boot.img, and flash it via fastboot.
Since you have an unlocked bootloader already, your device should be able to use an AOSP kernel.
From there you should be able to at least boot into recovery, and flash something from your SD card.
Id recommend just flashing the latest Cyanogenmod just to get your device up and running. From there you should be able to follow steps
get back to stock if thats what your looking for.
I hope at least one of these options work.
If not, like that last guy said, take it to a service center and get it checked out.
GOOOOD LUUUUCK!!

All ZL's are like that. Hold down till 1 vibration for reboot. Hold down till 3 vibrations for power off. The yellow reset button will not power on the device however. I figured I'd check just incase my power button decided to go for a sh*t.

[Q] My Xperia S won't start up. (Expected to Have Bricked) Full story inside

Hello everyone. This is my first post here but I have been lingering around XDA particularly in Xperia S android development forum.
Today, I'm having a problem with my XS that it won't start up after i've done a few things related to installing new ROM in it. I'm not sure if it's bricked or anything but here's the full story and please tell me after reading:
My phone is as follows:
Xperia S
Unlocked Bootloader
Rooted
1) I was in my Recovery Mode (not TWRP as I was using a 4.1.2 JB ROM before) with a ROM installed.
2) Wiped Cache
3) Install ROM from SD Card
4) Successfully went through the ROM install wizard and installed it perfectly. I could've just used the ROM as usual but suddenly..
5) Then I went into Settings, I decided to do a Factory Reset (With wiping the internal storage too) <--- I thought doing this would only reset the current recently installed ROM and not wipe the ROM itself)
6) It reboots and bring me to the Recovery Mode page
7) I chose reboot my phone now option
8) It rebooted with the SONY logo on for a while
9) And then the triangle settings logo with a spanner and screwdriver logo show up. The screen stayed for a while like 20 seconds
10) And then it goes black..... and I can't get it start ever again (yet)
I don't know what on earth was I thinking doing a factory reset... that was dumb of me
That's how the story went... what should I do?
I've tried:
Holding the power button for 20 seconds(or longer), no vibrations, led or anything
Holding the vol up button for 20 seconds(or longer), no vibrations, led or anything
Holding both power+vol up button for 20 seconds(or longer), no vibrations, led or anything
Connecting the phone to laptop using USB to see if it is detected by my laptop but no nothing happened though (I did not press any button while connected)
Enter FLASHMODE using the proper way (using flashtool and everything) but fruitless
Charging so that the Red LED comes out when phone runs out battery and resetted. But so far still nothing (6 hours+ charging)
So at this point what has happened to my phone? Is this considered 'bricked'? Is it over for my phone now? Can I do anything to get it back running? Please help.
Thank you so much in advance for reading and helping me out.

chill dude, dont panic, this was happened with me too a month ago, here what i did, i downlaod the .96 ftf file and flashed it in fastboot mode, in my situation, phone was on bootloop and your phone is turnning off so you can get into the fastboot easily,

have u tried sony update service? i broke my hp too... then i realised that i can actually use sony update service and press the volume down button and plug in my hp and update my fw to the original sony fw. hope this method helps for u.

Chill.
Alright dude, so chill. I recommend you to download Sony PC companion software and click on "Repair my device" from there. Then, you just have to follow the instructions and it should work. Tell me if it hasn't, I will help you

Would this work with a unlocked bootloader and rooted SXS?? Having problems with my data partition because I think it's corrupted. But I can still use my phone if it doesn't shut down the normal way.

I have the same issue with my Xperia SL.I wrongly install cwm recovery 6.0.4.4 by recover mode through option update.zip. Its done all the damage to my XSL. No Fastboot Mode, No Flash mode, No vibration nothing...Plz Help me guys...Plz

Yeah.
Yep. It should work.

Bricked - Help Needed!

So I got my brand new Z1C today and as you would do I rooted, backed up my TA and unlocked the bootloader. I also flashed on fastboot DooMLoRD kernel to get cwm.
I saw a new stock update for for 4.4.4 so I decided to try update via Sony PC Companion. Update downloaded but I was prompted that I could continue due to 'modified software'. So I decided to restore my TA to bring it back to stock and phone doesn' turn on
When I press the power button it vibrates but there is no display. If I wait a few seconds and press the power button it does the same. I can also still boot into fastboot mode. I attempted to flash a .ftf but I can't seem to get it into flashmode :crying:
Would anyone be able to help please?

Ha, that happened to me as well when I tried to restore the dreaded TA. But if fastboot is working, flashmode should too. Turn off the phone, press volume down and plugin usb. Iirc there's no LED confirmation in flashmode, but you'll see it in flashtool.

Flashmode managed to work! Phone seems operational now.
Deary me that was a bit worrying. Is it quite normal for you to have to flash a .ftf after restoring the TA or something? Nearly crapped myself...

There is an LED confirmation for flashmode, a shortly powered green LED. Fastboot is indicated by a solid blue LED.

You've done correctly, but you've missed one step, before flashing your locked TA and rebooting you have to flash a stock kernel, otherwise the "modified software" test in the locked bootloader will be triggered (by the unsigned kernel).
You have not bricked your phone, this thread is incorrectly titled as I'm sure you knew when you posted it.
