[Q] Phone doesnt start

Hello,
I'm using Arconium rom when i tryed to install the CM9 to test, well i just flashed with fastboot the new img from FX and install the rom. The instalation started but returned an error that i don't remember something about lt8i (my phone is lt5i).
I go to flashtool and tryed to get back to stock rom, but without sucess, now my phone show the Sony Ericsson logo and later it stay black.
Thinking i can fix this i relock the bootloader with flashtool files (found on Xperia Arc forum) and still not fix. Now i cannot unlock the bootloader "oem failed" and the phone doesnt start.
Please someone can help-me with a tutorial or something else ?

Take battery out, connect it to pc, press the back button and now plug in the battery again and see if it connects in flashmode then.

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

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!!!!!

Bricked ION.... need help

So, i have update my ion to ICS LT28h, my wife's ion we waited for the official AT&T update. I downloaded PC Companion, connected the phone, started the update process. I did all i was told on every screen. the phone never updated and now does not power on. no lights when plugged in to charge or connect.

1) hold the power + volume down for like 15 secs...(untill you feel a vibrate)
2) download flashtool at http://androxyde.github.com/
-----Install
3) download whatever FTF you want at http://forum.xda-developers.com/showthread.php?t=1752345
----move it to C:\Flashtool\firmwares
make sure drivers are installed(find them in C:\Flashtool\drivers
4) Launch Flashtool
5)select the thunderbold
----select the ftf
6)insert the micro usb end into phone (leaving the regular usb out of computer)
----it will tell you some instructions on how to flash but they are for different xperia phone
7) while holding the volume down button while the phone is off (From step 1)
insert REGULAR usb into computer
it should say flashing, or your comp might say installing driver, or it might just say drivers not installed..
ONLY IF YOU CHOOSE TO INSTALL LT28H FTF--------------repeat this step but now install the file from (FOR LTE)

If it is an AT&T phone do you really want to update to LT28h?

why not install lt28h
all you have to do is just flash the extra ftf
and then just change the APN

No reason to use the LT28h anymore since the LT28i and LT28at both have ICS and root.

In hope that someone's still looking at this thread, here is my situation: I tried flashing a prerooted image via fastboot and landed in a Sony bootloop. Then somehow I was stuck in fastboot-mode (led: static blue) and let the phone drain its battery. Now I'm able to get into flashmode but when flashing the chinese FTF with the Flashtool it stops at 1% with status "Processing .......sin" (sorry don't know the file exactly).
When I'm trying to power it up now the Sony logo comes up followed by an exclamation mark in a triangle... could you tell me what options there are left? I saw these prerooted images (http://forum.xda-developers.com/showthread.php?t=1669906), but there is none for the Ion, so I don't know what could be the next step. If I just had back my normal system... I used to flash my Galaxy S many times so I'm not that unexperienced, but it seems I really have a problem here:crying:
Any help is appreciated!

What model are you working with? And where did you get this prerooted image (the one you tried to flash)? From the link you posted I don't see one for the ion. Anyway, based on my own soft brick experience, you'll prolly need to let the phone battery drain, then charge (process can take a day or so), then try and flash your stock FTF via Flashtool.

Thx for your hints! It is kinda frustrating to wait until it is fully loaded, then try flashing, then load and wait again... but the 1%-bug seemed to be a major bug as it is fixed now in the new version 0.9.8 of the flashtool.IGonna tray again tomorrow and report my status. I already checked popfan's thread to get a point if mydevice really is bricked or not. So again thanks to all of you!
Just out of curiosity: is there a possibility to flash a prerooted ftf-file? I live in Switzerland where I bought the lt28h version. And I haven't found a prerooted. img file for flashing via fastboot. Just want to root it, custom roms etc. later

Alright, I was able to flash the chinese FTF and got my phone back working:laugh:
But I had to install the newest version 0.9.8 of the flashtool to not get the 1%-bug again. After this roooting via bin4ry's script worked well and now I'm happy happy happy. Thank you all!

I also had problems with flashtool 9.7. I used 9.0 with no problems. Didn't know about 9.8.

as the OP of this thread, thought i'd update. After reading a few threads i discovered the power/volume button trick. tried volume down with no luck, but power and volume up worked. PC Companion did not work in upgrading the phone. just kept telling me to disconnect my battery, and that if the batter cannot be disconnected to skip that step. But it wouldn't go to the next step. So I tried SUS. Worked perfectly.
So, My phone is running lt28h and my wife is on lt28at. There are some differences in the way data is downloaded. looking at my AT&T bill, the data downloads, i assume for apps that get updated, seem to be different sources. also my phone has significantly larger downloads even though we have similar apps. I do have a couple of weather apps she doesn't have that might be responsible for that.
I'd like to do some additional comparisons, but think i'll be flashing the AT&T rom on my phone soon.

[Q] Bricked Xperia S??

Hi,
First time poster here. I've done a lot of searching to find people with the same problem but can't. Sorry if it's out there and I've missed it.
Essentially I’m worried that I’ve bricked my Xperia S (running ICS). My problem is this:
First I rooted using this link: http://www.xperiagamer.com/Beginners-Guides/rooting-xperia-s.html
Then I installed CWM Recovery using the RecoverX project: http://forum.xda-developers.com/showthread.php?t=1773227
Then I tried to flash cyanogenmod 9 but failed.
I saw somewhere that it mught help to flash XTXperience so I did that. This failed and my Xperia S boots up to the Sony sign then fails and starts again just cycling through.
I can't get in to fastboot mode via CWM or otherwise. When plugged in to the laptop it is recognised but the computer can’t find the drivers (I've tried to instal manually) and then the phone reboots so the computer can no longer see it.
Can anyone help please??!!
Thanks

Keep pressing Unlock key + Volume Down key until you get 3 vibrates.
The phone is now off and you can connect it into flashmode and reflash your ics firmware.
The other thing you can do is going into CWM and wipe data and cache (that worked once for me when I had a bootloop)
--> you will lose all your data.
For CM you first have to install the kernel via fastboot and then go into CWm and flash the CM.zip file.

Thanks but that doen't seem to work. All i can get it to do is turn off with power and volume up. When it comes back on again it just cycles through again.
Can't get it to communicate with the computer at all - it recognises it but can't find drivers. then the phone disconnects itself in the reboot.

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.
