Maybe you need to update platform tools. I just went from 8.0 to 8.1 and i couldn't flash the flash-all for some odd reason but i got it to work by sideload the ota zip.

[Q] Point me in the right direction?

I recently got the Xperia S {No SD Card Slot, 32gb internal Storage}
I know it may sound silly, but could someone point me in the right direction for Flashing and Rooting this, what what's the best Rom/Kernal/Recovery Menu for this awesome device?
Just want to say, I do have experience on flashing stuff, installing roms ect
Just wondering what tools are needed to Root and Flash this thing
Thanks All!
this is the xS index for tutorials and guides and everything in between
regarding the part about best rom, you're always gonna receive a biased opinion on that coz that pretty much boils down to user preference

Check first: *#*#SERVICE#*#* >>service info>>configuration
if it says Bootloader unlocked allowed=yes then try as explained below ! It will definitely works !
I suggest you to first unlock your bootloader via the easy tool described at here http://forum.xda-developers.com/show....php?t=1560613
then flash the Doomkernel with the flashtool booting at fastboot mode. Before doing that never forget to install the necessary drivers.
The kernel is preloaded with custom recovery CWM and TWRP. While booting when you see doom logo pressing at 'vol +' you'll get CWM and pressing at camera button you'll get TWRP.
And flash the su and busybox package via recovery (CWM or TWRP)
for flashtool http://androxyde.github.io/
for kernel and su & busybox package: http://forum.xda-developers.com/show....php?t=2305591
& then enjoy Rooted jelly bean
ALL THE BEST !

You can root it, but you can't flash custom ROM's.

Install RootCecker and see if it is rooted. After that you can also try this SuperSU-1.25-Busybox-1.20.2-UPDATE.

Solved my problem by flashing the FULL firmware and not only the boot.img !
Could a mod delete the thread please ? Thanks !

How did you accomplish this? I can't get RSD Lite to detect my phone (although fastboot devices shows it listed) and I can't flash the full firmware via adb because I keep getting "Image not signed or corrupt". I'm really confused.

Please don't ask mods to delete threads because of successful outcomes - post your solution instead. Leave the threads up as they are a useful resource for others (at least those who search before posting! )

I kept getting the "Image not signed or corrupt" whenever I had to flash the boot.img but I ignored the error once to try and see if it had any positive outcome, and it worked fine !
Can't flash stock ROM, can you do a detail installation log?

Is ur bootloader unlocked or not??
If not try unlock ur bootloader than try it ll work
From what I can tell you will always get the "Image not signed or corrupt" error, but it works anyways. Idk why but it doesnt matter as long as it works . Motorola(Lenovo) has the instructions to flash stock firmware on your device, just download the firmware for your device and follow those instructions.

Did you only flash the stock rom or did you try to flash everything? If you didnt try to flash everything I would try that and make sure you have the correct stock firmware for your device before you do that. Theres not really much else you can do other than try flashing in twrp, but idk if twrp supports space chunks, but it does support images. If it really comes down to it, you can force flash the system partition in twrp, but you would need the whole system image and not space chunks.

Phone stopped working for no reason - can only get as far as the bootloader now

Tried looking through threads and have spent all day trying to fix it.
Phone was working fine a couple days ago until it ran out of battery. Since then nothing.
If I try to turn on normally I get stuck on the Google screen. Only other thing I can do is boot into fastboot/bootloader but from there, if I try Recovery mode it sticks in a bootloop
I think you have a hardbrick bootloop, There is fortunately a kernel and recovery developed by developers to overcome this problem, but you'll need a unlocked bootloader as it involves flashing recovery and boot.img. If you have boot loader unlocked, go to general section where you'll find a thread regarding the same. All the best
I tried that - flashed the recovery but when I try to launch recovery mode I just get a bootloop again.

Have you unlocked the bootloader yet? Do you get a success/failure when you try to flash using fastboot? Do you have twrp.img in the same folder as fastboot.exe?

Sounds like you need to update the fastboot drivers. While the device is in fastboot, go to device manager and look for an unknown device that is probably your phone. You'll need to update the drivers to have it show Android Bootloader Interface.

Applying back stock rom via fastboot should fix however you have not answered what you were applying via adb sideload so we can figure why you are in a bootloop in the first place.

Just sideload the ota but don't try to downgrade. You don't need an unlocked bootloader to adb sideload
