[Q] Can't flash my xperia arc

hello
im trying to flash my xperia arc to ics but it wont flash
it always stuck on vendor.sin or system.sin
plz help

use the latest flashtool and make sure verification is unticked before flashing

it still stuck on system.sin

when the flashing starts its all good until it reaches to flashing vendor
then the percentage is still the same 10%

The most common cause locked bootloader, have you have it unlocked?

how can i know if its locked?
i cant use my phone
i have the logo of sony and then i see a phone under a caution sign

here http://unlockbootloader.sonymobile.com/instructions
knowing that you can't use your phone, just follow instruction to unlock it (don't read step 1-2, just jump to step 3)
cmiiw

have u ever tried to unlock it?or atleast do u remember? C'mon dig up the memories

well its like a digital fingerprint of a device..they are unique..no two fingerprints are same..they are 15 digits code.. Just key in *#06# on your mobile phone and it will display its IMEI number..just follow the instruction to unlock the bootloader man..

or you can find your IMEI in your phone box if i'm not mistaken

You can find the IMEI underneath the battery as well.

Can. Turn-off phone, then press and hold "Menu" button. Connect phone to computer. The LED will turn to blue color. Now, it is in fastboot mode.

Then your bootloader isn't unlocked.

Keypad, type in *#*#7378423#*#*, Service Info, Configuration
If you see this
Code:
Bootloader unlocked: Yes
or this
Code:
Bootloader unlock allowed: Yes
then you can enter fastboot mode.
If you see this
Code:
Bootloader unlock allowed: No
then you can not enter fastboot.
Anymore questions?

hello,
i m using xperia arc s and having Bootloader unlock allowed: Yes
in flashtool 0.9.10.1 i flash my device completely, then i attach a phone for fastboot,
everything going right, but when i click Lighting ICON => fastboot => OK nothing happen
need your help urgent
thanks in advance

You have to make sure that your phone has unlocked bootloader, if it says "bootloader unlock allowed: yes" it doesn't mean your phone is unlocked, it only tells you that it can be unlocked.
If you have TrackID, try to play it, if it can be played, then the bootloader is still locked.
For unlocking, try the link below. And don't forget to thank them.

Put your phone into fastboot mode first (turn off your phone, hold down menu button and then connect the USB cable, blue LED shall light on).

Just DON'T install it. My Xperia Arc s is locked bootloader and i tried to install Ultimate HD Rom twice, but no hope after installation Sony logo stucks!
first time i solved it by using Update Service.
second time (NOW) still on Sony logo and Update Service isn't working, it says "You already have the latest software installed"
so for now I'm searching for a way to fix it

Just SOLVED IT! :laugh:
I flashed stock firmware using flash tool
stock firmware link by a member in the forum: http://www.mediafire.com/?rhr59r4o6oarnfx
then::
1. rooted the device
2. installed CWM
3. wiped everything
4. installed UHD and choosing just one app to install
5. unticked reboot
6. wiped Dalvik Cache ONLY
7. reboot device from CWM
8. Enjoyed UHD

UHD is stock based so it will work on locked boot loader, if it doesnt then you're doing something wrongly.

Not necessarily! choosing to install all the apps in the AROMA Installer causes sticking on Sony logo in locked bootloaders.

[Q] r800x - OTA after unlocked bootloader can't get back into fastboot

Successfully unlocked my bootloader this afternoon on my Verizon r800x. :good:
After rebooting, I stupidly accepted the OTA update, apparently didn't pay attention to the warnings from the Sony website. :silly:
Now I've got a nice brick.
My phone won't boot.
I can't get back into fastboot by holding the search button.
I CAN get into flashtool, but reflashing the stock FTF doesn't seem to help the situation
Any suggestions?

try unlocking again/downloading fastboot drivers? Sorry if this doesn't help, I don't know too much.

I appreciate the suggestion, but like I said, can't get in to fastboot mode on the phone itself. Don't get the blue LED. Wouldn't think that would have anything to do with drivers; Windows doesn't even acknowledge a device being plugged in while I hold the search button, but as soon as I let go, I get the GREEN LED and I can use flashtool.

Edit* Typing mistake
It doesnt matter if the xperia play drivers are installed on your pc. If the blue light doesnt turn on when your powering your R800x your fastboot is disabled. That means your bootloader is still locked.

I appreciate the suggestions, really, I do, but I think you're kinda missing my point here. Whether the bootloader remains locked or not is not the issue at the moment.
The official sony instructions I followed when I unlocked it had me put the device into fastboot mode. It worked great. But now, specifically, step 12 no longer works.
ALSO, my phone won't boot, which is the actual problem I'm having at the moment.
So, my phone won't boot, AND my phone can't connect to fastboot in order to flash a new kernel or whatever else I might need to do to unbrick my phone. The ONLY thing that works right now is flashtool. Flashing the stock Verizon FTF with flashtool did not remedy the situation.
Does anyone know how I can get my phone back up and running?

It is not possible to relock your bootloader in most cases, but this may be worth trying. http://forum.xda-developers.com/showthread.php?t=1134334 There is a link to an ftf file you can possibly flash to relock the bootloader then reflash back to stock.
If that fails, chances are you have a damaged bootloader and/or TA (trim area) due to the failed update. This link may help you. http://forum.xda-developers.com/showthread.php?t=1252019
Here is another link as well by wedgess, I think he uses the same method as in the link above. They will both most likely log into your computer using team viewer to resolve your suspected TA/bootloader issue. Read the entire thread, but wedgess's post is #27 http://forum.xda-developers.com/showthread.php?t=1957328&page=3 . Good Luck...

Did you back up your trim area? Because you have damaged it and will need a repair contact allejandrissimo about a bootloader and trim area repair... you can contact him at http://unlock-bootloader.com/

Have you tried flashing a different ftf? I have the R800at, and I couldn't unlock my bootloader until I flashed a generic R800a ftf. I reflashed to the AT&T R800at after the bootloader was unlocked - no problems. Think you could flash an R800i ftf just to get back to a bootable state and then flash the Verizon R800x ftf?

Yeah, I posted it more for reference than a solution...hoping it may let him know why flashtool can't fix the problem. The problem is most certainly the TA which is why I posted the other links.

Fixed.
I flashed "Xperia 2011 Range_FreeXperial_ALL.ftf" upon the suggestion of alejandrissimo. Rebooted, and in fastboot as I type this.
Thanks to everyone for their input, but the real thanks go to alejandrissimo for the solution.

[Q] Rooted, unlocked and on CM - how to return to locked, unrooted stock?

Hi all
I need to send my ZL to the Sony repair centre, as it has a serious fault.
I have a rooted phone, with an unlocked bootloader and am currently running CM10.2. Can anyone tell me how to relock? To do that, I need stock firmware, but I don't know how to flash it as I've seen warnings that I can't flash this while unlocked. The official Sony software doesn't let me update, as it recognises I'm running "modified software."
I've downloaded the latest flashtool, but that's it so far. All help appreciated and yes, I have looked but couldn't find anything that wasn't conflicting information.
Thanks guys.

After flashing the .ftf you can also use flashtool to relock your BL.
If you're in EU, you can send your device to service center even if you previously unlocked the BL.
According to European Union law, Sony has to prove that your problem occured as a result of the unlocked BL..
And even if you're not in EU, just try and send it in. Depending on the problem, they often don't check BL and DRM status..

MY PHONE IS FIXED! It took a couple of weeks, but the repair centre did a great job.
My phone is working and I love my ZL again. Thank you Sony repair!

Is there any way to relock the BL?

I want to return the device to stock and read on the sony dev website you have to flash a firmware but I do not see the Z5P, is there any other way?
thanks,
AC

Is there a reason why you need to relock the BL? According to Sony, there is no way to restore an unlocked BL.
Q: If I change my mind later on, is there any way to restore my device?
A: No. Once you have unlocked the boot loader, you will not be able to revert the device back to a locked or original state or restore the DRM security keys. You can however use the Flash tool for Xperia™ devices to flash a generic Sony ROM, although it will not receive automatic software upgrades.

You can relock it using flashtool. Just choose Xperia Z5 when the device window appears. I've already tried it, works like a charm.

Not sure if you can relock it without the back up drm keys. Since there isn't a backup program yet I would assume you've already lost the drm keys. I'm afraid you won't be to revert back to the same. Camera quality and x reality will be affected.

Some important things before you attempt the relock:
The DRM keys will not be restored after the relock.
You have to reflash the entire firmware or just flash the stock kernel before relocking the bootloader.
The phone should be on stock kernel, if you try to relock it with custom kernel the phone might brick.
Click BLU in flashtool and follow the instructions.

Turn off the mobile.
Press the BLU button in flashtool.
Press the volume down button of your mobile and connect it to the PC.
A pop up window will open, select Xperia Z5 (Z5P is not listed yet).
Another window will open, if you see Relock, press it, the bootloader will be relocked.
Let the process be over, then restart the mobile.

Relocking Bootloader
I had to unlock my device's bootloader to downgrade it to marshmallow because of the WiFi issue in Nougat, so i did it and didn't backed up the DRM keys(i didn't knew i am supposed to do it. It wasn't mentioned in the tutorial i was following or i missed it). Anyways now i am on marshmallow and i am unable to update it VIA xperia companion. It complains that bootloader is unlocked. Now if i lock the bootloader will xperia companion will work ? What is the affect of the lost DRM keys ? And if anyone knows the WiFi issue is sovled or not ?

Can confirm I did the same thing and forgot the keys (new to Sony devices vs. Google). IF you use the XDA FlashTool, you can re-lock the bootloader and Xperia Companion will recognize for a Factory reset of your device.

Did you restore the DRM keys from Xperia Companion or at least retrieve all the functions that DRM related (Xreality, Bravia engine ... )
