I have access to fastboot and flash modes, I can lock and unlock bootloader through flashtool, I can do anything... but no matter what i try, SO always crash after "starting apps" or something like this. I've tried differents versions of Cyanogenmod, differents versions of stock ROMs... no success. I've tried it in flashtools, PC Companion and Emma with same results. When SO tries to start and show me the homescreen, it freezes. I dunno what else to do.

My Arc just stopped working without a reason - one moment it just didn't boot up.
I had unlocked bootloader, phone was rooted and had stock firmware LT15i 4.0.2.A.0.42 Generic Global.
Battery was apparently dead, after replacing it i could connect to the phone with flashtool and fastboot. Still i couldn't boot up the system.
So - as i had no better idea, i flashed phone with Xperia 2011 Range_FreeXperia_ALL.ftf and LT15i_3.0.1.A.0.145_Global.ftf - in case radio was damaged or sth.
After that phone manages to boot up from time to time, but in less than minute dies off and reboots. Mostly it reboots before reaching to homescreen.
So i kept trying with flashing with newer firmware, but no success. its even gets worse - with every other firmware it even doesn't try to boot up.
Flashed firmwares:
LT15i_4.0.A.2.368_Generic Global.ftf
LT15i_4.0.1.A.0.283_Generic Global.ftf
LT15i_4.0.2.A.0.42_Generic Global.ftf
LT15i_4.0.2.A.0.62_Generic Global World.ftf
There were no errors during flashing - with any of firmwares.
Any thoughts what i should try to fix my phone? I have ran out of ideas
Try a different kernel and enter cwm. If you can do that then use flashtool, flash .62 firmware, put a custom rom on the sd card like arconium or se tweaked, fastboot dooms kernel v19 and attempt to flash the rom.
What kernel would you recommend?
For 2.3.4(.62) then doomlords kernel.

So i did flash my phone with .62 using Flashtool. Tried both Doomlord kernels -
ARC-DooMKernel-v19-BM-v2-lower_boot.img
ARC-DooMKernel-v19-BM-v2-high_boot.img
In both cases after turning the phone on i can feel a slight vibration like usual, but that's it. Nth shows up on the screen - so i couldn't enter recovery.
I even tried relocking bootloader and "repairing" the phone using PC Companion. Still nth happens during booting.
Would it help to erase boot, recovery, system and try again with newest firmware and DooMKernel? Or might erasing harm sth?
Flashtool shows me that loader version is: R4A066. Maybe i should update that somehow?
Try flashing .62 with flashtool then boot the phone, before using fastboot.
sinkster©
That's how i usually do it. Tried again, didn't solve the problem - won't boot up.
Assuming it's nothing obvious(user data not wiped, etc)as you've done it before. You originally flashed 2.3.3? And if you run that it boots, so could it be the 0% battery issue? I haven't had issues as I've never flashed a previous gb version, but the 0% issue was pretty common but now resolved(somewhere in here)
Yes, always have wiped userdata and it's probably not 0% issue - if i try boot up LT15i_3.0.1.A.0.145_Global Customized.ftf then i sometimes can glimpse homescreen for couple of seconds and it doesn't show battery as empty.
I understand that flashing Xperia 2011 Range_FreeXperia_ALL.ftf and LT15i_3.0.1.A.0.145_Global Customized.ftf won't update everything possible? Maybe i need to extract and flash some components from some newer ftf's or sth?
All I can think of is maybe the boot file is damaged, or corrupted, it seems to be happening to a few posters. Try connecting in fastboot, use 'erase boot', and maybe system too, and start again.
sinkster©
I have tried 'erase boot' too, doesn't help. What puzzles me, is why my phone chooses to boot up (although continiously rebooting) in 2.3.3? I would have given up hope a long time time ago, if it wouldn't boot up at all
Thanks anyway for trying to help, if any new idea pops into your head (others are also welcome to help me), please let me know
Maybe i do sth wrong what is very obvious, although in June '11 i already unbricked once that phone using the same method and it worked:
1) flashing Xperia 2011 Range_FreeXperia_ALL.ftf
2) flashing LT15i_3.0.1.A.0.145_Global Customized.ftf
3) flashing newest firmware..
OK i've been trawling the forums but so far i've not found an answer.
i've got a T-mobile branded arc and its bootloader is unlocked. it is running .62 firmware.
i'm trying to flash the generic uk .42 firmware but i keep getting the following error:
ERR_SEVERITY="MAJOR";ERR_CLASS="SECURITY_CLASS";ERR_STATIC="SIN_HEAD_VER";ERR_DYNAMIC="Failed to verify sin header";
i've tried a couple of different firmwares, and i've definitely got my phone in the right mode with usb debugging enabled.
can anyone help?
Thanks
Me again... I remembered a similar thing with someone's x10 a while ago, it was caused by low battery while flashing. The resolution was to repair the boot, which for the x10 meant a service centre. But you can use fastboot to do it, just connect in fastboot and use the erase command, erase boot, erase userdata, erase system. I'd give that a try.
sinkster©
Thanks for the response. Following something I'd read on the X10 forums I did consider doing a repair via pc companion but I wasn't sure what implications it might have following having my boot loader unlocked.
I'll give this a go and let u know if it works.
Thanks again!
ok could really do with some help now. still has the same problem with the added fact that my phone is now bricked.
Please help!!!!!!
after 'erase boot' have you tried booting a new .img?
D/L a rom that's cwm flashable to your sd card, boot into doomkernel and try flashing the rom(if you haven't already)
thanks for the quick response.
i've tried flashing the cyanogen boot image but sadly that fails. sorry to sound like a noob but i went to the github site to download doomkernel but for the life of me i couldnt find the boot image.
in the latest flashtool need to install the drivers or not? inside drives folder one..
I'm really sorry but i don't understand. I don't have any driver issues if thats what your getting at.
Are you able to boot kernels with fastboot?
hey sinkster.
ok managed to install different boot images (tried a few just to check) and all that happens is that i get the splash screen and it stays there.
still can't install any roms using flashtool. and to be honest i'm not sure how to do it using fastboot
any ideas?
thanks
Once you have installed the kernel, disconnect the phone from the pc and turn it on. When you see the kernel image, press the back button. This should send you into CWM and from there you can install a rom like "update.zip". On my girlfriend's x8 after flashing nAa kernel I was also surprised that it did not boot again to stock rom, but afterwards I pressed the back button which led to CWM and flashed a rom. Try to wipe data, cache, dalvik and battery stats also. The rom should work. If you notice any problems, just reinstall the rom again wiping data, cache, dalvik and battery stats (first time I got wifi issue and battery drain issue - android was taking 46% ) ). All the best. I hope I helped.
For flashtool just d/l a rom file(ftf), put it in the firmware folder, power down phone, run flashtool, click flash, select firmware. When it says connect then connect usb while pressing back(led is green) and rom should flash with a log on screen. this will flash an entire rom and kernel, or a baseband. For fastboot, open fastboot folder, move kernel(s) to folder, shift&right-click and select 'open command window here', power down phone and connect usb while pressing menu(blue led). In cmd window you can type 'fastboot devices'to check the phone is connected, to boot a kernel then type 'fastboot flash boot boot.img', or whatever the kernel file is called(I have 4or5 so name them individually)
so first use flashtool and flash the file here http://forum.xda-developers.com/showthread.php?t=1359303
that gives you stock rom/kernel; if you want a custom rom put it on your sd card to flash with cwm. if you want or need a custom kernel the fastboot doomlords kernel
These are the basics, you probably know all the above but just in case.
Gents thank you for your help. got somewhere finally. managed to flash BLENDMIUI onto phone andd got it working. for some reason SE Tweek does not want to work.
sinkster thank you for the summary.i originally mis-typed. when i said i didnt know how to flash a rom with flashtool i actually meant fastboot. but i'm now fully up to speed using cwm.
and thank you valy_cta, that got it working in the end.
its strange that i still get the same error when flashing any roms with flashtool though. tried about 6 or 7 different ones and i still get the initial error.
if i repair the phone with pc companion, would it lock the bootloader again?
other way round, you need to lock the bootloader before you update. Just unlock again, it'll be the same code.
sinkster©
ah the problem with that was that i had to get jinx13 to unlock it.
really what i want to do if flash a stock rom, which i still can't seem to do.
EDIT: since flashtool doesn't seem to work for me I found out from one of DooMLords threads that you can extract the ftf files and flash with fastboot. job sorted.
So it looks like I have some real trouble here. My phone will no-longer boot up, the only thing I can do is go into clockworck mod recovery, I can't flash a custom rom, and I can't go back.
The only way to connect my phone to the PC so that fastboot will recognize it's there is fastboot mode, but that does me no good. I can't install a stock ftf via flashtool anymore, it keeps saying it fails.
PC companion won't restore or fix my phone's original software, because it detects customs software and states it can't be updated.
Anyone know anything I can do?
Edit:
I figured it out myself, I used Sony's own Flashtool EMMA, I was confused due to the existance of the other Flashtool, but yeah, this is fantastic:

Hey all,
Haven't touched this phone in years, but was inspired to pick it up again yesterday. I can't for the life of me remember all the crap I did to it back in the day, but there was some "minimal" thing installed to it that made it play PS games better or something, and there was some LuPuS wolf thingy that came up when it booted.
Half the stuff I tried to do within the phone was crashing, so in my infinite wisdom I decided, "Hey! Why not just flash back to stock firmware!?"
And so the genius that I am, attempted to do just that.
So I found Flashtool and a nice stock rom and pretty much it did something, but then eventually fails every time as "Failed to verify sin header" and aborts the flash.
Now the phone is stuck in a loop, either the Sony Ericsson logo comes up, then a exclamation point in a triangle, or it goes into Flash mode.
I've tried several different stock roms:
R800i_4.0.2.A.0.58_Enhanced
R800i_4.0.2.A.0.62
And I've tried several versions of Flashtool:
flashtool_0.9.24.4
flashtool-0.6.8.0-windows
flashtool-0.9.11.0-windows
But no combination of any of those gets me past the error during flash.
I also tried the Xperia Companion, but it only complains my phone is locked and won't let me do anything. Of course it's not locked, and I can't even unlock it because it doesn't boot into anything.
I also tried the SEUS but it crashes upon launch (Windows 10).
Anything else I can do? Or is this phone toast?
Thank you in advance!
EDIT:
Alright, time for some extra silliness... and maybe I just don't understand what I'm reading here. So the sticker on the phone under the battery reports R800x, indicating the Verizon version.
The old Flashtool actually let me flash a stock Verizon ftf on there, but then it returns to the looping between Sony Ericsson/Exclamation point and Flash mode.
I ran the 9.24.4 version of Flashtool and attempted the same Verizon stock ftf. And here's what it said....
Current device : R800i
Also, the newer versions of Flashtool report this:
Bootloader status : UNROOTABLE
But the older copy of Flashtool reports I'm rooted.
I did try to get SUS working on another PC, but has same issues, seems to crash/die reaching out to a server that no longer exists.
EDIT 2:
Woohoo! Fixed! Continued to research all the info out there, and seems I just had to relock bootloader.
My phone isn't rooted, I ran the update from Xiaomi from the settings menu and after a bit of time my phone was stuck on the splash screen for miui. I tried rebooting multiple times but I couldn't get my phone to boot up.
Did some searching over the web and tried to recover my phone using the MIFLASH tool, which showed my phone but would say its locked. I tried the unlock tool and the phone still wouldn't unlock due to asking for auth.
The last thing I tried was the EDL method, when I plug my phone into my PC it's listed in the device manager as Android BootLoader and not a com port.
I did install the drivers from MIFlash, there were no error messages, but I did see some Chinese text listed.
Is there anything I can do or have I been going about it wrong?
Did you managed to fix your phone my friend?

Click to expand...
Click to collapse
.... you have to unlock your bootloader first.
