This is wayyy offtopic (but nobody checks this thread anymore; noobs and I are exceptions...);

DoomRecovery... Hmm.. If you're planning on flashing stuff that have long filenames, forget about it... It only shows either the first 5 or the last 5 letters in the file name...

I'd recommend you take TWRP recovery... It's way cool, touch.enabled, with a file manager and a system that prevents unwanted flashes... Plus, it's one of the rare recoveries for this phone that doesn't have an error while formatting /cache!

As for the kernel, I'd go for the ForzaFerarriLeo kernel... It overclocks the CPU to 1900 MHz, and as a bonus, it overclocks the GPU! Plus, it adds some extra governors and schedulers... (Also, the boot freq is set from 192-1512MHz, so you can't brick it by underclocking the thing...)

If your friend is a power user and likes benchmarks like Quadrant, take this one... It also does great with games... (underclockage (30 MHz) and over-/undervlotage also available)

:D
[Sony Xperia S, Acro S, Ion] waveboy:
Actually my friend is quite the noob.......wanted a Nokia but i convinced him to get this......just wanted a recovery for backup purposes......i guess ill flash twrp then thanks:)

Also if u could recommend a kernel which is stable (should not have sod) and has good battery life it would be great.
[Sony Xperia S, Acro S, Ion] someone755:
Battery life really doesn't matter, since that 5% really isnt much... You can always set some governors and check that there are no background processes (under settings>development)...

So, as said before, Forzaferrarileo's kernel...

There are others, but as far as I'm concerned, this one packs the most punch while being the same battery friendly as the others :D

need some help. i can only stay in bootloader for 5 seconds? ive tried all drivers in this thread
[Sony Xperia S, Acro S, Ion] someone755:
Do you only hold the vol up button? Or are you holding any others? (happened to me, I held the power button with vol up)

Also, as said before, tell me your PC's OS and if it's 64 bit or not...

You could also try another usb port... Or another cable...

Or, maybe you're too slow. I know that my phone would do the same if I'm not quick enough... If nothing is going on and if I'm not using the connection, it simply shuts off...

[Sony Xperia S, Acro S, Ion] uDroid:
FTF for Xperia P? Or i can use booth FTF?
[Sony Xperia S, Acro S, Ion] someone755:
@chio:

A file does not 'weigh', dear sir. And yes, the space on your disk it takes is correct. That is, if you're talking about the bootloader RElock one... If you're talking about a stock ROM, those are about 400 MB...

@uDroid:

To relock the bootloader of a SXP, kindly PM good sir DoomLord. Those FTFs are under testing, so the relock might fail, or brick your device. (Please don't use the ftfs posted in post no. 2, they aren't intended for your device!)

Use at your own risk... But you probably know that already...

Did you, good sir, not read the first two posts carefully?

60 KBs is about right for the RElock ftf...

[Sony Xperia S, Acro S, Ion] g3ar:
*#*#7378423#*#*
[Sony Xperia S, Acro S, Ion] someone755:
Really, that also tells you about relocks?

Doesn't work here, just says either 'unlockable' or 'unlocked'...

Meh...

Also, I seem to be getting an error about cache in recovery... Something about not being able to mount /cache and that it's missing a log file...

Is this in any way connected to the bootloader being unlocked?

(And yes, my chip isn't fried, I checked... I just can't fix it...)
[Sony Xperia S, Acro S, Ion] MarkMRL:
Do you guys think that they can tell that the bootloader has been relocked, and thus claim your phone is out of warranty? My phone is perfect and I don't think will break anytime soon, but you never know. I have more than one year of warranty left, it would be a waste to put it out of warranty yet.
[Sony Xperia S, Acro S, Ion] someone755:
There's probably a way, but the warranty people don't care.

All they care about is if they're able to flash a stock FW with some sort of an 'Emma' tool for locked bootloaders.

Basically, all you have to do before taking the phone to the repair shop, is relocking the bootloader.
[Sony Xperia S, Acro S, Ion] tOrNadO™:
Hi DooMLoRD, bro i have one doubt? I recently bought Sony Xperia S.. I am willing to root the device and flash custom ROMs. But if i have to root, do i have to unlock the bootloader? This may be a silly question, but since i was a Samsung user before and i happened to see different procedure here to root the phones, so this doubt.. Also is it possible to revert back to the way it was with the touch buttons below the screen?
[Sony Xperia S, Acro S, Ion] someone755:
The procedure to root is always the same! You just need the su binary inside /system/bin or /system/xbin ! Uhhhh, why don't people get this!?

Yes, you can root without unlocking the bootloader... I think Binary has a great tutorial... Google it...

But if it's unlockable, I don't see why you wouldn't want to unlock it... Think of CM, AOKP, MIUI!! Think of TWRP recovery!!

And what are you talking about here:

Touch buttons? You mean the capacitive (home, back and menu) keys or do you want nexus-styled onscreen buttons?
[Sony Xperia S, Acro S, Ion] lifesucks:
I tried on acro s and kept getting sin header error. Please help. Thanks very much in advance
[Sony Xperia S, Acro S, Ion] someone755:
Sin header error? Are you sure your phone is unlockable?

Also, did you use this exact method?

Get a recovery for locked bootloaders and format EVERYTHING...

Then flash a stock .FTF via FlashTool and try again...
[Sony Xperia S, Acro S, Ion] Tyseyh:
I have what will seem like a very stupid question.

My bootloader is unlocked, been flashing ROM's etc, easy.

But now i find out that Bravia Engine only works with a locked Bootloader.

So, I am simply considering re-locking my Bootloader to at least test the Bravia Engine.

my question is, Re-locking the bootloader seems easy, just flash the TFT file. but if i want to re unlock it, do i have to go the official way? Btw i unlocked it the official way to start off with.

or am i better off just leaving it?
[Sony Xperia S, Acro S, Ion] someone755:
What are you talking about?

There is a tweak to get BE working on unlocked bootloaders. Search...

And what other method besides the official one is there?

See, EVERY method is based on the official way, so basically, they're all the same... FlashTool, the other flashtool, the Poor man's FlashTool, the official way... You can unlock with every one of them. but you can only relock with a program that allows .FTF file flashing...
[Sony Xperia S, Acro S, Ion] Tyseyh:
I wasn't aware there was a tweak to get BE working on Locked Bootloaders, i had no reason to search seeing as i heard people mentioning it only worked on locked bootloaders.

thank you for clearing that up about the locking and unlocking of bootloaders though.
[Sony Xperia S, Acro S, Ion] -PiLoT-:
i see youre a helpful guy. or you think so. but the reason behind your millions of posts in this thread and your staggering 49 thanks is the cockiness you show. it makesw people want to hunt you down and kill you
[Sony Xperia S, Acro S, Ion] someone755:
I am truly sorry if I sound cocky, but those aren't my intentions.

My knowledge of the English language isn't on par with the average American or UK person...

About the helping people part... Yes, I do think I am mostly helpful, since I am the only one that checks for new posts in this thread daily and replies as soon as he can. If I leave this thread (which I won't), I don't think newbies would get their answers (or at least not as soon as they'd like to get them).

If you want me to stop helping, I will, but I thought XDA was a place for people to help each other... I see now that I was sadly mistaken...
[Sony Xperia S, Acro S, Ion] -PiLoT-:
nono you misread my intentions. it wasnt to stop you from helping. its how we all learn. it was more context and dialect of the written language. in some of your posts you almost seem mad you feel obligated to help. and maybe curbing this would make people more responsive to what you teach them
[Sony Xperia S, Acro S, Ion] someone755:
Well, as I said earlier, my English isn't really good...

It's good for chatting on IRCs, but I really don't know how to explain things... Even in my native language...

Agreed then, I will try and improve my English, so that I will be able to explain things in detail without looking angry :)
[Sony Xperia S, Acro S, Ion] Tyseyh:
You did sound cocky, it was a little off putting, but seeing as English isn't your native language then I do understand somewhat why you sounded as you did.

All's well that ends well eh. :)

Relocking BootLoader after flashing with Emma?

Hello,

I've a little question, I flashed my Xperia S back to stock firmware using the Emma tools from Sony.

If then I flash the FTF file to relock the bootloader, will it boot directly or will I need to flash a stock firmware in FTF format as well?

Also should I uninstall Emma before using FlashTool?

Thanks in advance.
[Sony Xperia S, Acro S, Ion] someone755:
The answer to both is: no.

Emma doesn't interfere with flashtool and the phone boots directly to android...

Though I think it deleted my recovery the last time...

Also, the kernel is reverted to stock of course...
[Sony Xperia S, Acro S, Ion] DrKrFfXx:
I'm having some troubles relocking the bootloader of my Xperia S.

You see, I have the mic of my Xperia S not working as it should, and I have to send it for repairs under warranty, but I must lock the bootloader back to normal. Everytime I try to boot into flashmode on flashtool, I get a blue screen on Windows 8 x64. I think it is complaining about a driver. I unlocked the phone's bootloader on Windows 7 like three month ago, and updated to W8 recently so I have no access to W7 right now .

Do I need anything else aside from flashtools to make it work under W8? Does it work at all under W8?
[Sony Xperia S, Acro S, Ion] someone755:
It works on w8,but you need drivers... Do you have them installed correctly?
[Sony Xperia S, Acro S, Ion] linnx88:
So let me get this straight as a noob, after I go through this procedure and unlock my bootloader, do I get root automatically? Because I'm on the latest 2.55 fw which didn't allow me to root using BinAry's method. Or will an unlocked bootloader only allow me to install an unofficial ROM that's already been rooted? :silly:

Thanks!

PS

I have successfully unlocked the bootloader. What's the easiest way to root my ICS 2.55 fw?
[Sony Xperia S, Acro S, Ion] someone755:
Get the fastboot zip from the link in my signature...

Once done, find a kernel with recovery on xda (Google helps). Make sure the kernel is in the .elf file format.

Then just flash it through recovery.

Then, Google 'su zip' and find and download a zip file and place it on your phone.

Boot into the recovery and flash that zip.

And there you have root, just like it was meant to be done.

Also, the bootloader is only there to prevent you making changes to the kernel. Once unlocked, u can swap kernels, but that also makes it possible to flash ROMS with custom kernels (note the awesomeness of AOSP here...).

The bootloader thus has nothing to do with root.

Also the firmware you have installed doesn't change this root method, so can use it on any phone with any android version. You just need a recovery...

(if your phone is a Xperia S, I recommend twrp recovery. You can Google 'twrp' and find your device, then flash that kernel...)
[Sony Xperia S, Acro S, Ion] linnx88:
Ok cool, I was able to flash Advanced ICS Stock kernel that is pre-rooted. CMW working!! Thanks a lot!!

Finally I'm back to my Titanium Backup and actual working Ad block app!! Hooray!
[Sony Xperia S, Acro S, Ion] someone755:
(I can read what you wrote before you edited, here are short answers):

kernels are on the boot partition. Every kernel. So, that basically tells you how to flash a file:

fastboot flash boot [path to file]

to explain: the program 'fastboot' (in the directory you are in now) will flash the [path to file] file on the 'boot' partition of your phone.

That goes for kernels and recoveries (elf, img and sin).

What do you mean with 'CWM recovery in the zip file'?

You were going to flash a kernel with a recovery, why would you want to flash a recovery on top? :eek:

My tutorial requires you to download and install the program BootloaderUnlock (the other zip file attachment). Fastboot by itself won't give you instructions on how to flash files, though the 'help' feature always 'helps' :P
[Sony Xperia S, Acro S, Ion] linnx88:
Yes yes you're right. Was a bit confused before I went through it. Everything's working now, and you're right, it wasn't necessary to flash CWM, it's included in the kernel as well as root.
[Sony Xperia S, Acro S, Ion] rahilsayed:
Please tell me how should i know if i have unlocked the bootloader or not,Xperia SL??
[Sony Xperia S, Acro S, Ion] DooMLoRD:
Just flash only loader.sin using flashtool and see output in flashtool log window. Incase the bootloader is UNLOCKED then you will see "bootloader status: ROOTED"
[Sony Xperia S, Acro S, Ion] jaxzkeren:

Hi.. I want to know what exactly wil happen if i unlock bootloader? I know Sony OTA won't work, TrackID will be lost(I use it barely, so no prob wit tat). But i have a doubt tat i think i read somewhere about it that we lose our touch capacitive buttons below the screen permanently if we unlock the bootloader? Pls correct me if i am mistaken.. Also can anyone tel me tat wt exactly is lost if we unlock the bootloader? Thanks in advance.. :)
[Sony Xperia S, Acro S, Ion] someone755:
Unlocking the bootloader removes drm... TrackID will work, Sony had an update to make it work... There's still some debate whether it disables bravia engine...

And no, the capacitive buttons always work... I have no idea why somebody would make a stupid statement like that...

What you lose are the drm keys and, for some reason, oems say that /data must be formatted due to 'security reasons'... So it wipes your /data partition...

Might I add, this is a perfect example for using titanium backup... :)

P.S.

Also, Ota updates shouldn't be installed... Some of them CAN be downloaded, but in most cases, they'll brick your phone...

And no, warranty, in most cases, is not lost, as long as you relock the bootloader before handing the phone in...

[Sony Xperia S, Acro S, Ion] someone755:
If you have root and unlocked bootloader, get goo.im manager from play store and install a recovery from in there... It's TWRP recovery...

[Sony Xperia S, Acro S, Ion] rahilsayed:
Thank you for the help but i don't know how to install it via goo.im manager

i am seeing .tar .img .zip files of twrp recovery when i searched it in goo.im manager?
[Sony Xperia S, Acro S, Ion] someone755:
There should be an option to install a recovery or something like that...

If you want to explore the wonderful world of fastboot, get the file from twrp's official site and flash it through fastboot... It's easier once you figure out how it works, but it'll save your life in the long run...
[Sony Xperia S, Acro S, Ion] someone755:
what if you just cd to the directory where you have fastboot?

Then why not just copy and paste the EXACT command that you got in the first post?

Why in the world would you put '<' and '>' and '[' and ']'s there?

The command below doesn't have these, why would you use them?

fastboot -i 0x0fce getvar version

I don't want to be mean, but seriously, why?
[Sony Xperia S, Acro S, Ion] takuhii:

[Sony Xperia S, Acro S, Ion] someone755:
Flash a stock ROM...

If you've had a custom ROM installed before, it probably had its own kernel.

When you relocked the bootloader, you flashed the stock kernel with that, thus the custom ROM cannot boot... (thats why you need an unlocked bootloader to flash custom ROMs (with custom kernels)).

So, either flash a stock-based ROM or flash a stock ROM FTF with FlashTool...

---------- Post added at 09:48 AM ---------- Previous post was at 09:47 AM ----------

I can't ever flash the stock FTF with an unlocked bootloader...

I always get an error...

Either my phone is weird or you're wrong here :P
[Sony Xperia S, Acro S, Ion] DooMLoRD:
just use the correct FlashTool and loader.sin

i have been using Flashtool since the X10 and i even work on developing it... so i am pretty sure that u can flash stock FTF irrespective of bootloader status...

Hi guys. I've been trying to unlock my bootloader for a while now. But when I want to enter fastboot mode, the blue light only turns on for a couple of seconds then reboots by itself. Windows recognized the device as a fastboot device only within that few seconds time frame. Is there any fixes/workarounds?

Thanks..
[Sony Xperia S, Acro S, Ion] someone755:
PC OS and version, please

Also, what (if any) drivers do you have installed (that is, do you have FlashTool drivers or did you install them from a folder (like the classic Windows way?))?

Also, what cable are you using? I myself have found that some old Nokia cables don't work... (Old Nokia products mean quality. So that must mean there's a TON of other manufacturers out there who make incompatible hardware... Just a guess)...

Please supply us with the information needed to help you. As already discussed a million times before, nobody can help if we don't have info. (for a guy with 3 excellent phones and an awesome Android tablet that hangs around XDA since 2008, I'd really expect you to know that...)

How do i relock my bootloader when running a custom ROM?

[Sony Xperia S, Acro S, Ion] kubekpop:
Hi. So does it mean if I relock bootloader, then warranty service still keeps my IMEI and they refuse warranty service? Or only if they detect custom rom?
[Sony Xperia S, Acro S, Ion] someone755:
@Tyseyh:

I'd recommend first locking the bootloader, then flashing your 'ROM of choice' on top.

@kubekpop:

They detect if you [quote from Doom] '**** up your device' with doing things that require an unlocked bootloader (or root).

The warranty people only check if your phone can be flashed with a special version of 'EMMA' (like normal EMMA, but only for locked bootloaders)...

If that's fine, they'll fix it.

OR, if the phone won't boot at all, they'll check what you were doing with the phone before it crashed. If they see, for example, that the CPU was overclocked, or that you changed the kernel, they'll say; 'We can't help, your warranty is void'...
