[Q]

so i have rooted xperia arc. noticed that there were new update (4.0.2.A.0.42). so i resetted to default settings cause otherwise it wouldnt let me install that update, then after about 5 mins of updating arc shutdown and now it wont turn on.. so i ask what should i do?

was your arc bootloader unlocked when you did this?

When your BL is locked, just flash it via SEUS.

yes, bootloader was unlocked.
thank you for quick replys

There is a fix in the sticky's
For future only people who unlocked with setool can update via FOTA, SEUS and PC Companion.
Unless you relock your bootloader

that was usefull! thanks, only problem now is that it wont connect to pc cause pc cant install "s1boot download".

You follow the link in the tutorial closely? Needed drivers are in the flashtool directory

found them but dont really know which one i need or where to put..
edit: now that flash started but it tells me to turn debugging and uknown sources on... but how cause i cant turn that even on
edit2: after reading almost full sticky thread tried that xperia play firmware which someone said it worked, now when i try to turn it on green led blinks.. is my phone piece of junk now?

so anyone know what should i do? it wont turn on, green led blinks when i press power button, phone vibrates when i press menu button (to start fastboot).

In Android Developement of Arc is a sticky with a fix for FOTA bricked phones, just do that

[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...

Your wrong using ftf will not relock your bootloader.

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.

HELP!!! Boot Loop - Update Error

Don`t pass of this! And Sony Companion do it the same, error! FlashTool nothing, can`t into recovery. Sorry For My Bad English...

Here, try this. It saved my device from being bricked.
http://developer.sonymobile.com/downloads/tool/flash-tool-for-xperia-devices/

Download a working genuine sony FTF and try again.
Reboot in fastboot and flash it.
I forgot to mention that you must have installed adb and fastboot drivers. Google them.
Flashtool driver pack i think it was.
Install them. If you have problems, disable driver signature verification. There is info on the internet.
After that, try again with the clean FTF.

Emma FlashTool no read it, it need bootloader unlocked. Already tried with many FTF but I have "loader" error

Screw the emma flashtool. It is useless.
Try with sony flashtool.
There is a bit of difference.
http://forum.xda-developers.com/showthread.php?t=920746
Get it from here.
There is info on how to use.

He already said that FlashTool isn't working for him. So I thought he unlocked his bootloader, which is why I posted EMMA.

Xperia Arc S (LT18i) Can't enter fastboot mod, no blue LED and Insert Simcard problem

Hello.
I've searched forums and found some threads like this but my problem is a bit like them and a little bit different at the same time.
Sorry for my ENGRISH
I have Sony Ericsson Arc S, (LT18i). My brother bought it from UK and bringed to me, to Türkiye (Turkey). As you guessed, Turkish simcards didn't work and my brother gave money to a mobile phone seller to unlock it's simlock. After this, we able to use phone with Turkish simcards in Turkey.
The other day, after a couple years, I wanted to install a custom ROM on my Arc S.
This is how everything started.
I searched XDA forums and took notes. How can I do it, which programs needed etc.
Preparing
First, I did a factory reset.
After the phone opened, I changed usb connection to MSC, allowed Unknown sources and opened USB debugging.
I installed Flashtool 0.9.10.0. I readed a couple posts about that, previous versions gives no errors.
Under /drivers folder I found a driver package. Installed it with just Flashmode, Fastboot and Sony Ericsson Arc drivers selected.
Pluged in my phone and checked if it's drivers installed or not. Success. I can see my phone in device manager.
Installing
I readed a few guides and they say I have to Unlock bootloader. So I clicked Bootloader Unlock option in Flashtool. Followed the instructions, gone into flashmode, restart, gone into fastmode with pressing menu button and plugging the usb cable etc. There was a window with my IMEI and I followed the instructions and I get a code (long, including letters and numbers) from official sony website. I entered this code to that window and it said my bootloader is unlocked.
After that, I rooted the device. No errors.
Installed CWM via Flashtool. No errors as far as I remember.
AND THIS: Flashing a ROM. I found an Android 5.0.1 ROM and it said that I had to flash boot.img. So I did. I mean, I tried. I GOT ERROR. And, BUM. Something happened and I couldn't open the phone.
After a search, I found a solution says using Sony Companion may restore the phone. I tried this. Follow the instructions and my phone opened with ICS 4.0.4 instead of old version, 2.3. And now, it says, INSERT THE SIM CARD.
I searched the forums about 2 days and didn't find a solution to this. It ignores my sim card. Then, I saw a secret code about simlock and bootloader status and entered that code *#*#7378423#*#*
Under Simlock option,
They say there must be X's. At least the first one must have X on simlock screen but it hasn't. And there are all 0's. No X's, and zeros. So this is bad i think.
Under Configuration
In configuration section, it says Bootloader Unlock Allowed: No. As far as I learned from XDA forums, that means bootloader is locked again. Because it must be unlocked or unlock allowed: yes.
So i tried to unlock bootloader again. I had no idea what I've done. First, it said go flashmode. Done. And it said go into Fastboot. I couldn't. No Blue LED.
You see the thing? => Flashtools says go Fastboot to run Bootloader unlocker. I can't. Forums says I have to bootlocker unlock to enter fastboot. Bootloader unlock to enter fastboot. But enter fastboot to boot unlock. Wow.
Lastly, I tried flashing custom TFT's to see if it can flash or not. IT FLASHED. I can flash STOCK TFT's, even a KERNEL i downloaded from here. I can Root, install Busybox ( I don't know what is it haha), Install CWM 5.0.
But since it can't see my Sim Card, i didn't try to install custom ROM.
What I have to do? How can I unlock to simcard lock if it's locked? is my bootloader locked?
My brain hurts.
I wrote all things because it's easy to solve a problem with more information. So a few things more:
I use Windows 10.
I didn't use original cable at first. But you know, no errors now. It's not important at this point I think.
I unistalled mobile device from devices manager and delete the driver. I installed inf file from sony website and selected it for ADB driver. It says now Sony sa01102 ADB Interface Driver. If Fastboot needs correct drivers, I installed from it's official site, offical one.
I didn't tried another computer because again; no errors from Flashtool.
THANK YOU ALL.
I maybe copy this to other websites.

About Loader.sin Error
I did get Loader.sin Error a few times. But when I use previous Flashtool version, there was no loader.sin error.

"In configuration section, it says Bootloader Unlock Allowed: No. As far as I learned from XDA forums, that means bootloader is locked again. Because it must be unlocked or unlock allowed: yes." It means you cannot unlock bootloader! Its not possible , your phone is locked , i mean you cant run fastboot mode , its locked , install stock firmware and thats all , you cant install any custom firmwares as Cyanogenmod or custom kernel anymore. If you can't understand it sorry because english is not my main language.

Unknown error unlocking bootloader!

Hi folks,
I have waited more than 788 hours to unlock my Note 5 Pro bootloader. When I have connected connected the device in fastboot, mi unlock tool has not recognised my device. I had to reinstall adb drivers and reboot the device multiple times. Now it is recognised and started the process of unlocking the bootloader. The tool is struck at 99% and after few minutes it says "-1 unknown error unlocking the bootloader"
Using the same account, sim and device. Please help.
Thanks
Update:
Unlocked the bootloader successfully. Issue was with the fastboot drivers.

I have unlocked the bootloader successfully. The issue is with the fastboot drivers. Try rebooting in fastboot mode and connect to computer. Under device manager check if your device is recognised as adb interface or bootloader interface. If it's adb interface then you are good to go. Else click update driver and select the 2nd option to update from computer. Again choose the second option to choose from a list and in the list select adb and click next and proceed. Now your device should be recognised as adb interface. Now try unlocking.

Can't . You have to wait the whole time

Just turn off USB Debugging in the developer setting if it is on and restart the device to bootloader and use the latest version of the MI Unlock tool. Hope it may work. It worked with me.
