Oh trust ne I searched a lot
Wrll while I was waiting for a reply, I thought of installing drivers once again and there I found that the drivers were unsigned, so I was gonna force unsigned drivers anyway by a guide.
I made this thread because at that time I didnt know that, I tried on xp but there was no cmd by shift+ right click, and on win 7, the 5 sec problem persisted and my phone was like dead and I had to try three button combo to revive it.
Anyways rightnow a download is going on, will ask solutions as and when problem appear
Thanks
On a sidenote hate microsoft for windows 8 hassles and sony for delaying jb further

Xperia S Fastboot problem

So I was about to root my Xperia S and started reading a guide, it said that I would need to load some files into the phone using fastboot. After a while I figured out how to fastboot and managed to get the popup on my computer once, however, I didn't install it that time and now when I try to fastboot again I get the blue LED on my phone, my computer makes some noises indicating that something unusual have been conected, nothing happens and the phone shows the Sony logo.
Does anybody know how to fix the problem and get the popup on the computer to re apear.
I run a 64 bit windows 7 home premium.
Thanks.

Hi HugNikanor..
When I Unlocked The Bootloader and Was Going To Start Root Process.. I had The Same Problem..
If I remember Correctly It Was a Driver Issue..
In FlashTool Folder There Is Another Folder Called Drivers.. Have U Tried Installing The Fastboot Drivers From There..?

I don't have anything from flashTool. The guide I used is this: AddictiveTips . com and searched for Root xperia S (it's the one that doesn't say gingerbread.) if that can help in any way.

Ok.. You Are Trying To Root Using Fastboot Mode..
I Assume You Have Already Unlocked The Bootloader.. Which Firmware Version You Are Using.. Is It Sony ICS 6.1.A.0.452..?

So for Unlocking Bootloader You have to use fastboot mode.. ok
and after that, for rooting it should be done using flashtool in fastboot mode..
so here is the thing.. Download The Flashtool first And After extracting the files You'll Find a Folder Named Drivers.. first Install The Fastboot Drivers Even To Unlock The Bootloader..

Got that part working now, now just to fix to problem with the phone going out of fastboot mode way to fast. But I think I have seen a guide for that somewhere else.
I will report back after future succes or failures with the project.
Got bootloader unlocked!
Thanks alot for the help with Flashtools. All the guides I found just asumed that you just knew a lot of things which kinda complicated it for me.
Again, Thanks!

Hi,
I can't connect my phone in flashmode nor in fastboot mode. Whenever i connect it in flashmode/fastboot mode my PC stucks(hangs) and i have to restart it again i have installed all the drivers for all devices but still the problem exists. Any help in this regards???
Also to mention i'm using Windows XP SP3 and flashtool version is 0.9.1.0.
I have also one more issue when i connect my phone to the charger when it is switched off the phone does not charge at all it simply shows me the sony logo and keeps showing it again and again but never charges. In short when my battery is complete i cannot get it back to life due to this problem but thank god that i have installed CWM on my phone.
Thanks for helping i'll also post this in the development section also.
I have no idea to your problem, but I would guess that it have something to do with you using xp, or maybe some damage on your phone.

Hello I have an Xperia S, with bootloader locked and recently installed a ROOM in order to get the 6.A.1.2.55 with root.
Installed from a ZIP from recovery mode following this post:
http://forum.xda-developers.com/show....php?t=2009672
Now when I try to do step 7 (flash kernel and Baseband) Using Flashtool, Im unable to enter to the mode; when the windows prompts me, I turn off the phone, press and hold Vol up connect the USB but nothing happens, only the Sony Logo and then the icon of charging battery, I also tried to turn off the phone while holding Power button + Vol up (at the same time) and get the 3 vibrations, but the same result when I connect, the logo and the charging animations/icon..( no LED of any color or anything)
Im using the latest Flashtool version (0.9.9.0) with the drivers intalled (even though Windows security constantly pestered me about not being able to identify the source and signture) on Windows 7 64 bits..
Thank you..

Problem

Hey guys,
I am facing this prob. for quite some time. Whenever I use flashtool and connect my Xperia Arc in flash mode, the computer hangs without any warning and I jus have to restart it. FlashTool says that drivers for the device is not correctly installed.
Pl. help me with regard to this.
I am presently running CyanogenMod 9 Nightly version.
Flashtool: 0.9.8.0
Awaiting your reply
Epic Fail, Wrong Forum............................................................................................................Reportet.
reinstall driver , format your computer ??
And please note that here Development Forum
pls post it to right place -____-
Don't be so mean. Have you ever got into despair when having a problem? Have you though that the forum name is not the most relevant one? By the way, where should a question like this be posted?!
TO answer the question... it is not easy so solve. You will need to clean your PC of all possible traces of old drivers. To do that, with the phone disconnected, go to Device Manager on PC (google if you don't know how). Then, remove any possible references to your phone using the information from here: http://technet.microsoft.com/en-us/magazine/ff184583.aspx
After that, install Sony PC Sync software. Follow the steps. At the end, it should tell you that you should connect phone.
Everything should work now (your phone will be finally re-discovered).
Before you do that, also try to disable Debugging on the phone and set the PC connection to MTP.
Good Luck!

[Q] xperia ion lt28at Please Help

I have read through the other threads and from what I understand I may have a "soft brick" it also mentioned to ask first before I do anything, so I apologize in advance. I tried to update to JellyBean 2 days ago and had a game that froze I did a hard reset not knowing that it could potentially cause problems, I have done it in the past with no issues. PC companion downloaded the update and I followed the instructions as usual held volume key down plugged the usb in and it initially recognized my device but only for about 3 seconds. Now everytime I plug my phone into the PC it either says "unknown device" or it doesn't do anything other than start charging it. I have tried usb debugging mode switched between MTP and MSC modes all with the same result. Also I was reading the thread for "RECOVER SOFT-brick" and it provided the link for the flash tool and my device was not listed. Thank you in advace for your time and patience.

I am not sure what the update service is that you mentioned, I tried the repair option with pc companion but the computer wont recognize my phone when i plug it in. Tried while it was off held the volume down and plugged the usb in, the device looks like it is doing what it normally would when I am updating but then it just goes to the charge screen. So I assume that is not the repair that you were talking about, unless I am doing something wrong. I don't have the option of bringing it to sony right now because I am working overseas right now. Unless maybe I mailed it in I didn't want to go that route because it is my main source of communication for while I am out here.
Thank you again for your time.

I already have that update service I used it when they released the update before JB it was a new build#, the program worked great unfortunately it doesn't do me any good now because it still doesn't recognize my phone and I tried several times with all the diffirent modes and options combinations I could think of. I am not near a Sony store and will not be for some time, I may have to try something more drastic or just purchase a new phone. Thank you again for your assistance

Settle down dude, dont do anything drastic. First read up on soft bricks. Now i need to know does your device boot? you dont exactly describe the condition of your phone. If possible try flashing it with flashtool and the latest JB ftf (to enter flash mode on our lt28at ion you connect the phone to the usb cable, hold vol down and connect the usb cable to the pc when flashtool tells you to).

My apologies, yes I believe my phone does boot so far the only issue I can see as of right now is that I cannot connect to my laptop or anyone else's. I have tried holding the volume key down and plugging in the usb numerous times with no luck it only charges when I do this. I have read up on soft bricks and it seems simple enough but I didn't know for sure what the problem is with my device, other users had mentioned that along with usb issues I could have messaging and phone call issues. I have been using wifi and the tango app for communication for the past four months because of where I am located there is no service and also the reason I have not brought it in to a store. But back to flashing the device I have never attempted it on this device or any other so I was a little nervous about permanently bricking it, I looked at one link in another thread that had the latest JB ftf and my device was not listed. Also is there a specific flashtool you recommend? Thank you for your help

That was exactly what I thought initially as well so I did a back up on my computer and installed win7 ultimate after it was installed I made sure all of my drivers were working and up to date, I also tried it out on several other computers just to make sure it was the phone. Also just to be sure my computer was working properly I had one of the other guys here plug his phone into my computer and it came up instantly.
I think I may have misunderstood the fast boot question I thought the question was if the phone would boot from being off.

I followed the instructions from both of the threads, but I keep running into the same problem. My device is not listed among the drivers to install, I scrolled to the right on each one just to make sure it was not part of a group. Before I got this reply I followed the tutorial basically the flashtool for dummies like myself and down loaded the correct firmware for my device. I followed the instructions to run the flashtool selected my firmware started the flash tool, it told me to hold volume down while plugging in the phone just like I would with pc companion and probably 3 secs after plugging it in the only thing that would happen is I would get the usual windows prompt that "the device is not recognized" I thought for sure this was the solution, perhaps I am missing a step? I am officially at a loss now lol I even went to the threads specific to the ion lt28at and it was all quite simple right up until plugging in, any more insight would be greatly appreciated.

I appreciate the link but that was basically instructions on how to start the flash tool properly it seems, I still can't get the flash tool to recognize it is plugged in. I believe the issue is with the device driver, problem is the ION lt28 is not in the list of drivers. Is there another one that I am supposed to use that is compatible? I thought it had to be specifically for my device, again I appreciate all the help you all are giving me this is becoming a frustrating process for what seems so simple

Try Flashtool-drivers [ do a googole search ] download it and see if you can find the drivers there.
I know this is over a month old, so i'm sure the info is no longer helpful...but this 'driver' issue has plagued Ion owners since the phone released...
in reality...its not a problem...but just 50 members all sort of saying the same thing in different words...
the Lt28 series of devices does NOT need any model specific driver from that install_drivers.exe app in flashtool's directory...You ONLY have to install the flash mode driver (for an Ion with a locked boot loader) or flash mode and fast boot drivers for unlocked bootloaders, if you play on using fastboot with flashtool for various services...
you DO NOT need to install that entire list of drivers for an Ion...they have nothing to do with this series of phone...all other necessary device drivers are automatically installed when setting up PC companion, or simply plugging in the phone (if you skip pc companion)...
any issue with flash tool and it saying 'device drivers not found'...you're missing the flash mode driver...and nothing else...

[Q] Xperia Arc Disaster! Help please!

Hi everybody,
I own Sony Ericsson Xperia Arc (LT15i) which no longer lives under the warranty time period. It became extremely slow, so I decided to flash a new ROM on it in attempt to see if that made it any faster. I rooted it and installed ClockworkMod Recovery on the phone and attempted to flash Xperia Ultimate HD 5.01 through CWM. The installation went perfectly fine, however after I did the reboot my phone doesn't get past the Sony Ericsson logo.
I've looked up all sorts of ways to fix soft bricked and bootlooped Arc's but none seem to work. When I try to use flashtool, I can't seem to be able to connect the phone to the computer and Windows comes up with "USB Device not recognized" and flashtool automatically aborts flashing. When I try to use PC Companion to repair the device, Windows doesn't recognize the device and neither does PC Companion. The same thing happens with Update Service.
I cannot enter flashmode, cannot get anywhere past the Sony Ericsson logo (including trying to access ClockworkMod Recovery) and cannot seem to get Windows to recognize the device. All drivers are installed both from Sony and flashtool.
Is there any other way I can recover my device? Thanks in advance for all help!

Hello,
I can pretty much understand your situation, but this is where we start to have a better understanding of our own device and learn from our mistake.
In fact if you want to use flash tool, you will need to prepare your PC to recognize your mobile, by means of installing appropriate drivers, commonly known as Google SDK drivers.
I shall resume somehow here and try to find a good link for you to read :cyclops:
1. Your PC need to have latest version of JAVA
2. Install Google SDK, choose appropriate drivers and apps to be installed
3.Install flashtool and appropriate devices drivers.
Try to follow this link :
1. Installation of ADB drivers and SDK : http://forum.xda-developers.com/showthread.php?t=1830108
2. Flashing Kernel and Rom. Be careful with compatibility and other issues, you always have surprises here
http://forum.xda-developers.com/showthread.php?t=1996665
The above link is for HTC if im not wrong, try searching for ARC you will find it, there are loads of tutorial posted on XDA..
Here you go : http://forum.xda-developers.com/showthread.php?t=1508585
Dont forget read and read until you understand every single terms.
See Ya . .

The problem is that you have GB kernel, but using ICS ROM. These 2 do not work together.
Try another USB cable and/or USB port and try Flashtool/PC Companion again.

Tried that. Still no results. I've also tried using fastboot, and yes I did install all the drivers as well as the Android SDK along with the Java DK. When I enter
fastboot devices​
I get no response... When I try to flash a kernel using
fastboot flash boot bootARC.img​
It says waiting for device forever. The phone is plugged in and the blue light is on. The screen is still off though. When I connect it in fastboot mode to Flashtool it has the same problem (doesn't recognize the device).
Would Sony be able to fix it for me if I handed it in? Even though my warranty has been void for over a year I could probably just pay for the repair. At this rate I doubt it's possible for me to fix it...

Well that might be the issue,W8.I have W7 and XP never had a problem.
Did you try to run flashtool and connect the phone via usb(turn it off and just connect it don't hold any buttons,if that doesn't woek try turning it on and then connect it)-so that way flashtool might detect the device.Hope you'll get it to work.If nothing helps than try searching on google about these issues for win8.

Did you increase your system and data partition into 419 MB and 440 MB? Because if you haven't you'll get a bootloop with Xperia Ultimate HD 5.01 since this rom needs that space. I read that you have to flash Arc S kernel to achieve this but im stuck at this point because the partitions won't change for me :/
To use fastboot, install the drivers by this method.
The only working method to install fastboot on Windows 8.

P8000 brick

Hi guys
This is my first thread here, so I hope that it is in right place.
Yesterday I received my elephone p8000 but I noticed a problem which I tried to resolved by myself. When I tried to switch on the phone, there was only a dark screen with booting sound. Recovery mode doesn't work so I thought that sp flash tool help when I use format and root phone and go in some way to recovery mode. I put on memory of phone a supersu, a then I format my phone by sp flash tool. I want to upgrade it by sp flash tool but I can't because I have got some problems with usb drivers, I see some errors during processing upgrade.
I have read the topic bbs.elephone hk viewthread&tid=6616&page=5&authorid=12774#.VfDLzZfLJ6I ( I can't post a full link here as a new guy ) and I had a hope that when I install these drivers it will help me, but it doesn't work.
Probably I made a mistake because I don't know too much about android enviroment, but I have the feeling that I'm close to repair my phone by myself, I would like to try some mtk 6753 usb drivers and MediaTek PreLoader USB VCOM (Android) but I can't find any on windows 7. Is there anybody who could help me? I'm sorry for my english, I tried to explain everything as good as I can.
Regards.

Hi,
so you basically flashed your phone even though you knew that your USB driver is unstable? Don't do that!
Does your phone still boot (in any mode)?
Check if you can at least get into the bootloader. Hold volume up and power at the same time. If you can't, you probably screwed your device. Oh, and fix your Windows setup! The driver needs to be stable in order to flash the phone again!
Same problem!
you have to instal the package you have download with the tool.
i tried it on my laptop and i had all errors with the drivers. i tried my desktop (win 10 ) and it worked very wel.
i hoop i helped you!:good:
use PDAnet driver!!! And use spflash-tool to reinstall the stock rom!
