Develop Bugs

Stuck at Sony logo

So, I was using .431 generic global world (GGW) build for my xperia arc till today.
Today, I noticed that .587 GGW came out and decided to update.
I already had unlocked bootlader with no root with .431.
First, I backup everything & factory-wiped my phone.
I tried to enter flash mode with no avail for over 10+ tries.
Then I decided to trick SPC update to force my phone into flash mode.
It put the phone to flash mode as I thought.
I successfully flashed .587.
Then I started to root.
I used the guide at this post:
http://forum.xda-developers.com/showpost.php?p=26805903&postcount=3
After the 2nd step I noticed that I can't enter the flash mode even with SPC trick.
I deleted all previous usb drivers and settings.
I also reinstalled all sony software and drivers from scratch.
I was still unable to enter flash mode.
Then, I noticed I could enter fastmode.
So, I renamed the ftf file to zip and extracted the files.
Then, I used fastboot mode to flash new kernel.
Phone was rooted and working.
I installed CWM and got a full backup.
So, I thought why not try a custom mod after the root.
I decided to try Hybrid MooDeD JB-ICS 100.0.
http://forum.xda-developers.com/showthread.php?t=1526717
I followed all the instructions to the letter and made the install.
The phone asked for reboot and when it rebooted it got stuck at Sony logo.
I checked the thread a little bit more (my fault for not checking all before but in my defence it's 101 pages..) and it seems it's kernel is based for .431 and I was using .587.
So now, I can't enter the flash mode nor fastmode and the phone is stuck at sony logo.
Help please...

can you enter recovery if yes then flash appropriate rom
and also try to remove battery for 30 or more sec and connent phone while holding back button to get in flashmode or search to get in fastboot

OP: How come you can't access flashmode or fastboot mode? Then you are doing something wrong. Besides, problem is that you didn't install proper custom kernel for the ROM.
And previous ROM has nothing to do with it, doesn't matter which ROM you had earlier, new one will install and delete/replace all the files.

I realise that. I put all the info up to OP so that ppl won't waste time by asking me what happened exactly.
Nevertheless, I really can't access flash/fastmode at all. I tried removing the battery and start clicking all the things before putting the battery back on. But nothing happens. I just see the sony logo.

Yes I did read all post but for your kind information if you can boot upto se logo most probably you can get in recovery.... And he cannot go in fast boot so taking off battery is too helpful someTimes
And think before you post

So as soon as you place your battery back in does your phone turn on ?
if it doesnt i think you should be able to access either flashmode or fastboot mode

When I put the battery back, nothing happens. Phone doesn't get powered up. As soon as I try the key-combo for flash/fastmode, phone starts up as if it's going to enter the modes but only sony logo shows up and gets stuck. I really have no idea how this could happen.

Damn !
hmm thats odd isnt it ? Are you sure your holding the specified buttons before pressing the power on button ? Sorry about all the Questions just making sure

if you can boot upto se logo so your semcboot is not broken
so now tell me if you could enter fastboot before you unlocked bl?
and try to unlock it again using test point method (there is also a free one with S1TOOL if you had bl unlock allowed = yes if you could recall) i recommend not to use paid one bcoz you can pay that to sony to recover it and may be after that you could get into fastboot mod
if it didn't helped try to repair semcboot or trim area contact alejandrissimo for that it also follows testpoint method and its free
i think now only way to connect phone to pc is using testpoint!!!!!

nevertheless, I had left my phone at a local repair place. It seems they fixed the phone but downgraded to GB.

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.

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.

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..

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..

[Q] Xperia Arc won't boot after CWM crash

I am new at all this stuff but i think I'm starting to somehow get a hang of it. I rooted my phone this week running .587 by downgrading the kernel etc, you know. Today I wanted to try another rom so I followed this guide: http://forum.xda-developers.com/showthread.php?t=1955248 To install Xperia Ultimate HD on my phone with a locked bootloader.
However during step 8 CWM shut down and started to boot. But it doesn't start and I'm unable to get back into CWM My computer won't recognise the phone so I can't flash the kernel or do a complete reset using SUS. What do I do? is it save:able?

Been doing flashtool ftf recoveries whenever this occured. Do not power on arc s with it stuck. let flashtool self boot to flash mode and you will be back in buisness again.

if you could tell me what to do a bit more precise I'd really love you! like a small guide

I assumed you have flashtool since you mention about kernel downgrade. if no get it installed
the step actually same as flashing the kernel with phone power off.

Mate, press the back button while you connect to PC and flashtool will show "device connected in flashmode" than select a firmware to FLASH and FLASH it. After the process is done disconnect and power it on... =)

I was also stuck at Sony logo and it reboots every time just after sony logo. Then i used flashtool, flashed using "LT15i_4.1.B.0.587_Kernel.ftf".....
Now it boot further, but only to XPERIA logo, and then reboots....but certain times i have seen it getting past the logo, like it shows a display asking for pc companion, even the taskbar too with time and blutooth icon on it....but all of a sudden it reboots. i have tried rebooting more than a 100 times, while taking out battery everytime.
Also, I'm not able to get into recovery mode. I tried this using the combination of power on, and when sony logo appears, pressing and releasing volume down repeatedly. I hope i'm doing right.
So what should I do?? am not able to use this phone for a week...
Please help me out.
Ok got it working. I just unlocked the boot loader from sony bootloader site(sorry couldn't post the link, because of low post count)
So, it booted up but show error as soon as put a sim, that "Unfortunately keypad has stopped working".
I figured out the culprit, it is the build version with i flash it. I reflashed it with LT15i_4.1.B.0.431_kernel.ftf, now it working fine like a charm.
So much relief...!!
Hope this may help someone too...so i shared!!!

or its too bad that no one is understanding
64 views till now
no feedback
is every think ok out there ???

thanks for sharing this, it works as I did the most same way except making everything packed greatly as what you have done
the best of this was you made all files in one, extremely good for ones do not have 4.4.2 and 4.4.3 ftf files in hands
I guess most of guys do not want to try flash-power off-flash...

Maybe what you mean is only kernel,not the entire ftf file,right?

At step 4 you only flash the 4.4.2 kernel, (deselect everything else) not the entire .ftf or you'll end up with 4.4.2 on your phone. Similarly, at step 10 you only need to flash the 4.4.3 kernel, not the entire image.
You forgot to mention that an unlocked bootloader is required to use flashtool.

Also, if you unlock bootloader you lose warranty so backup TA partition before you proceed to keep warranty.

Well written guide. Success here. Rooted now.

Without unlocking your bootloader you cannot use flashtool, I suppose.

HELP Needed - Sony Xperia M Dual on BootLoop after Bootloaded Unlocked

hi guys, need some help here. I'll try to keep this short and precise to describe how i ended up in the problem
i did not have (and do not have) any custom recovery installed before this day, never needed to go in recovery mode.
1. Root using TowelRoot app (no problem so far)
2. Installed SuperSu app (no problem so far)
3. Unlocked bootloader using Fastboot and followed official sony guides
---after unlocking the bootloader, phone went in bootloop. It can go in Fastboot mode. It can go in FlashTool Mode, but when I tried flashing FTF file, it ended up in boot again. instead of Sony logo + colourful animation. now it's stuck at sony logo only.
I tried using Sony PCC, to repair it but it says there's any error, can't proceed - it's a dead end.
Do you think it's cause I actioned in incorrect order i.e. should have unlocked bootloader first before rooting?
Thanks for all the help/advices/direct links.
