[Q] Problem with Bootloader - Xperia Arc Q&A, Help & Troubleshooting

I have a problem with my Sony Xperia Arc S (lt18i) and i think it is related to a corrupted bootloader. Since i've installed a CyanogenMod ROM, i can only install CM based Roms and i want to return to the Sony Official ICS but in the Flashtool it gives "failed to verify sin-header" and doesn't complete the flash process. During Sony's Unlock Bootloader Method, it says that my bootloader is already unlocked. But when using S1tool, it says that is locked. I could really use a hand on this :/ thanks anyway.

Did you try using more than one file with Flashtool?
Have you tried Sony's EMMA tool?

Already tried inumerous files, same result ("failed to verify sin-header"). Sony's EMMA doesn't allow me to flash at all, but i can't remember why :/

Try again and tell exactly, what is happening, why you can't.

i guess the pics speaks for themselves. Tried several ways of flashing (no final verification, no TA, no Kernel, no bla bla bla) as i saw in other threads and i get the same error, again and again. Unless i flash CM based roms (9,10,10.1,10.2,11; all of them work fine) i can't flash anything. Any other rom i flash, my phone just keeps stuck in a black screen after the logo and some of the kernels give me a brick pic. I don't know what i can possibly do

I expected information of what happens when you use Sony's EMMA. Why else did I only quote the EMMA part of your post?

What happens in Sony's EMMA is also in the screenshots. I open the program, plug my Arc S in flashmode and that's what happens. I've also uploaded the other screenshots because, in my opinion, there's nothing wrong in giving more information than asked.

However, information that you posted but not used or related is redundant. Sometimes it's better to give what is required and leave it at that.
Back to topic, did you try using fastboot to flash a kernel? You can try using fastboot.exe to flash a kernel.

Yes, i can flash any custom kernel via fastboot, but unless it's a kernel to use with a CM Rom, it's no use. For example: if i flash ICS Doomlord kernel, it gives me a brick pic after the logo, as well as any other ics kernel. The ones i can use is fxp, legacy xperia and others CyanogenMod kernels to use with CyanogenMod roms. Anywho, my objective is to flash the original ICS 4.0.4 ftf through Flashtool, or at least a Sony Xperia custom ROM, not a CM one

Nope. Every stock kernel and custom kernel i've flashed doesn't let me enter the recovery (except, of course, the CM ones). It just shows me Sony/Sony Ericsson logo and a brick pic after that. Tried several buttons (kind of in despair), none of them let me enter the recovery. No tapping, no holding, nothing. Just the brick picture.

Post a screenshot or the log of when you install kernel via fastboot.

[Q] Recovery Problems

Hi, I've got the Xperia Arc S running gingerbread 4.0.2.A.0.42. I've rooted it using Super One Click and installed Rom Manager. But when i try to install the CWM i says that i have already one. Then, i tried to boot into it and I can't! I have a locked bootloader. Please Help! I want CM10
B
u
m
p
for cm10 you need to unlock your bootloader to flash fxp/cm10/aokp kernels.
if u cannot unlock it due to warranty issues try out other ICS custom roms in dev section which support locked bootloader.
many of them have features of ICS-JB combined .
Sony devices have no recovery partition, so you can't install a recovery on the normal way. If you want to stay on gingerbread, install DoomKernel v22, so you automatically get a recovery

Incorrect - flashing a kernel requires a unlocked bootloader end of. Now for the installation of CWM on locked bootloader, it can be installed to the system partition and booted from there, you could use this application to install the required for you http://forum.xda-developers.com/showthread.php?t=1437840.

Thank you, but I know it. I told that CWM maybe will be released in the future for locked bootloaders, so we will be allowed to flash custom kernels, sorry for my poor english

You can install CWM through x-parts, from playstore:
https://play.google.com/store/apps/...1bGwsMSwyLDIxMiwiY29tLnB2eS5DV01pbnN0YWxlciJd
Or using RecoveryX:

Both methods will be deleted if you wipe system partition... which you'll pretty much do when flashing a zip rom.
there are good Roms out there for locked bootloaders... I've tried these 3 and they are great!.

[Q] How does one revert one's Xperia S back to stock ICS from Cyanogenmod 10?

I'm asking because I specifically flashed another boot.img for Cyanogenmod 10.
Now, what are the exact steps I need to take to go back to stock ICS?
Do I need to flash a stock boot.img first, with fastboot or something, and then flash a stock ICS zip from ClockWorkMod?
I'm not really experienced with any of this, I've flashed only about 3 times but none of which required me to install a different boot.img (isn't that the kernel file?).
Any help would be amazing!

I always follow 2 steps in CWM
1.Flash advanced stock kernel and reboot.
2.Flash stock zip Rom.

Can this advanced stock kernel be flashed from within CWM as well as the ROM? I used something I believe was called fastboot for it.
And the kernel is indeed the boot.img then?

If you want to go back to stock, dont flash anything..
Now reverting back to stock is much easier as sony has released an official flashtool, just download the tool and latest firmware and flash it using the tool..
Once again dont flash any kernel or any rom if you want to completely go back to
stock.

Yep sure There are 2 versions of advanced stock kernel. One is flashed via fastboot and another one is flashed via CWM.
Then, on CM, Pac, Para which Rom are not based on stock one, boot.img is exactly the kernel

I tried this, but I couldn't get the official flash tool from Sony to work.
I apparently had to have a company when making an account to log in. Very odd.
I assumed this other flashtool made by probably xda developers did the same thing, but that one always gives me an error that I need to install the drivers first. Yet I've used this program before and back then I already went through all the hassle to install the correct drivers.
And now I don't know which drivers to install anymore.

You need to follow the instructions in sony's developer website for installing the flash tool..
Did you install the drivers using the drivers folder in flashtool??
And does your phone get recognized by the flashtool, I mean does it show your android version etc etc..??

Thanks A LOT!
Sony's beta flashtool, Emma, works like a CHARM!
I initially forgot to copy the customisation file from the zip to the installation folder. Thanks for reminding me to check the instructions
The unofficial flashtool couldn't recognise my phone, but Sony's one could.
Thanks so much for answering my questions, I'm starting to learn how it all works! If I could, I'd give you 10 thanks. But I think that's against the rules c:

[Q] Can't flash back to ,62

Hello! I'm having a problem with my xperia arc S, I tried to install a ROM (ULTIMATE HD 3.1) but I didn't have the wifi modules, so my phone got stuck on boot, so I figured that I got a bootloop, and went to flash the kernel (562), root again again and flash the new kernel (587) to try and install the ROM again, but the phone didn't root, but I flashed the .587 kernel and can't flash it back to .562. I can't figure what's the problem the flashtool says it's flashed but in setting the "compilation number" just says that it has the new kernel.
So my problem is how can I flash back to .562 and root the phone? I already tried this a few times ([url]http://forum.xda-developers.com/showthread.php?t=2118343[/url]), but it dosen't work. what else can I do? Try with another kernel?
I also tried this, but it didn't work http://forum.xda-developers.com/showthread.php?t=2219711. I don't know if it helps but i have the bootloader locked.
Sorry if repost, google but didn't find anything related. thanks anyway.

If you cannot repair with Update Service, try PC Companion. It should offer the repair function.

Had a similar problem, caused by wrong kernel (at least i think so). Anyho, there was no "repair" option for me either.
What you should do is:
- Flash back to stock GB firmware (0.62)
- Root (using eRoot, it's a one click procedure.)
- Install CWM using RecoveryX is the simplest way i'd say
- Flash the kernel which Jared proposed (can't remember which one sorry)
- boot into CWM, and follow the instructions to install UltimadeHD rom. I'd suggest Tesla's instructions, they are fail-proof. Remember to click on "unlocked bootloader" if your bootloader is locked.

You have to switch it off first before connecting, then connect while holding back when they ask you to in Flashtool.
Just to be safe, remove the battery and replace it after switching off.

Well first you need a unlocked bootloader.
Then, you have to flash a ICS kernel for an ICS ROM (using fast boot)
LuPuS is a good kernel and is pretty stable too.
After that just install the ROM through CWM.

But i'm sure that Emma (son'ys flashtool for unlocked BL) will work. Here is a link

[Q] I want to reset Xperia S

So I have the Trinity Rom installed, unlocked bootloader, trinity x kernel and a rooted Xperia S. I want to go back to the beginning, to start everything from scratch. Can someone tell me a step by step procedure to revert to the old system because the PC Companion won't repair it because of the custom firmware.
Thanks!
Download and install Emma(the sony developers tool). That can reflash your phone to stock firmware. Or flash an ftf though Flashtool.
Also, there is a sop on the xda website regarding relocking the bootloader if you want to do that.

OMFG, what were you trying to accomplish by those actions? Why relock bootloader? Only thing you had to do is to flash prefered FW via Flashtool.
