Hi, first of all, may thanks to jerpelea for http://forum.xda-developers.com/showthread.php?t=1126358.
I have try to upgrade my arc from 2.3.2 (unlocked bootloader) to 2.3.3 using the phone and I have brick the phone, now is with 2.3.3 running very well.
Now i'am looking for a way to root the phone, and i do not find anyware the way, but in few posts, some people talk about it, I do not know if it would be with locked bootloader.
If this question is on the forum, i don't find it.
Thanks
Flash a rooted .img if you are on unlocked device or flash a generic .181 ftf and root + OTA to get 2.3.3. Got it?
Its all in the forum under Android Dev section. Lookie lookie!

Bad idea mate, with the unlocked bootloader
hi, but if a do a downgrade to rom 2.3.2 (rooted), and update to 2.3.3 using OTA, my phone will brick, and i will need to make a flash using the http://forum.xda-developers.com/showthread.php?t=1126358, won't i ?
Yes, so it is advisable not to try the OTA updates AT ALL!
Like datagubben said, just flash an already rooted ROM.
Cheers!

Currently is not possible to re-lock your unlocked phone.
here is the quot from website:
"Please note that there is no turning back when unlocking the boot loader. You will not be able to revert the phone to a locked or original state if you unlock it. Also, if you brick the phone, it is your own responsibility."

if ur already having ur 2.3.3, just flashing recovery kernel made by either doomlord or bin4ry to have access to recovery mode, then, you can flash superuser package (aka root) to have ur fone completely rooted.
here's link of bin4ry recovery image (ps: this is just a live boot, so do exactly as what it said)

@smokada,
I'm not sure if an OTA update will work for you even if you relock your bootloader (after flashing 2.3.2) as the DRM files have been wiped but it's possible to update via SEUS, which would make you lose your root.
@silverwind,
You're a bit behind the times mate. We've been able to lock the bootloader for quite some time now i.e. from the end of June. You can follow that thread here.
[The DRM files which were wiped while unlocking the bootloader can't be retrieved by locking the bootloader again.]
EDIT: LOL! I didn't realise that so many people posted before me with the answer.
It has been a while since I flashed the stock FTF file for 2.3.3 R800x... and I cannot remember if I have to relock my bootloader prior to doing so. Do I need to re-lock it before I reflash the FTF or is it safe to just flash away?
Flash away. You can't relock the bootloader on the testpoint unlock, anyway.
I can relock my bootloader just fine. Done it before. So its okay to flash on unlock bootloader..... good. Thank you.

Hello,
You mayby think, aigen someone who ask for relock bootloader. I have try different tut's, bus it doesn't work.
I can't find an stock kernel and rom. Anyone help please.
Thanx,
Harypjotr
Hey,
Did you have to unlock your bootloader using setools or omnius, or the 'test point' method?
If so, you can't relock the bootloader.
Otherwise, flash the ftf from this thread using flashtools: http://forum.xda-developers.com/showthread.php?t=1134335
I can relock my bootloader, but I can't get the normal kernal and firmwire from Sony.
When I try to update, I get a sign, you alreddy get the newest version of software....
(Sorry about my terrible English)
I fount my orriginal .tft
Flashed, flashed the relock, and it works
Would it at all be possible to go back to stock kernel without having to flash an .FTF? It would lose the unlocked bootloader if I were to flash an .FTF, right? CDMA, so it's a pain to unlock it again. (Would I have to pay again? Hrm...)
Edit:
Or is it unlocked forever, regardless of what I do, once it's unlocked?
Once you unlock, it's unlocked until you choose to relock when using flashtool.
You may use flashtool and an SE .ftf firmware to "un-flash" back to stock kernel.
While at the same time keeping the unlock state.
As you will only relock your phone when you press the relock button before you start flashing.
So NO Worries; just flash it. And also, to save time, you can choose to flash only the kernel when using the tool.
If you unlocked your bootloader via a paid testpoint method then it cannot be relocked, regardless of whether you flash an FTF via fashtool.
To my understanding it is possible to extract the just the kenel.sin from an FTF file and flash it via fastboot or flashtool.
I will look it up for you then let you know.
Edit: Stock Kernels can be flashed, with the command: fastboot flash boot kernel.sin
Make sure you place the kernel.sin in the fastboot directory of your AndroidSDK

Sure, you can use flashtool
No, you can't. If you take a TA backup, unlock bootloader, flash CWM and then relock the bootloader with the backup you took earlier your phone will be soft bricked until you flash stock kernel again. The reason is that with locked bootloader, only kernels oficially signed by Sony can be booted, if you relock the bootloader while you have CWM the phone will refuse to boot because it'll see you're using CWM, not a signed kernel from Sony...
