I relocked my phone. Can I unlock again to install ICS beta? - Xperia Arc General

Would I go through the same procedure as if I was stock?
I was previous running a rom, used flashtool to relock and put the stock rom on my phone. Can I just go through the steps again since I'm stock again or will something screw up?

Exact same process. Even the same code...

Sure , u can

I'm not sure I understand entirely what you're asking, but from what I've read you would need a bootloader that was not locked and had been signed with a key that your current bootloader will accept. Do you have one?
I think he means the following:
IF our bootloader wasn't locked and he would flash a custom ROM but wanted to return to the stock one, if he can flash his stock bootloader back to prevent bricks in the future.

Manually flashing latest verizon 2.3.3?

Hi all
Just unlocked my bl and rooted this awesome phone. I notice I am on 2.3.2 right now but would like to update to 2.3.3.
I have heard there is a method to manually flash this update without losing my unlock/root.
Could anyone point me in the right direction?

I've heard of people flashing it OTA and then doing Flashtool to recover it, because your Play will be bricked afterwards... I still don't know if you would still have unlock and root after that though... I'm thinking of jumping ship to CM7.
Would someone mind referring me to the steps of ota and then unbricking with flashtool please?

Wotanclient 3.4 Update after unlock, doomkernel etc.....

Could I upgrade my phone with this utility? I've unlocked bootloader. Also I've installed Doomkernel and flashed a custom rom. Now I want to restore the original firmware and I don't want to brick my phone.
Use that or the flashtool.

You won't lose the lock but you will the root.

Downgrade to 4.1.2 possible for nonrooted ?

Hi everyone I was just wondering if its possible to downgrade my nexus from 4.2.1 to 4.1.2 if I'm not rooted. I'm currently not interested in rooting my device so is there a way to do it without rooting/unlocking?

I can't flash things because I'm unrooted. So I don't think this method will work. Correct me if I'm wrong.

Anyone know?

I do not know for sure but I quite doubt it.
I am curious as to why you want to though. Not that there's anything wrong with wanting to downgrade, of course.
Have you tried one the took kits available? Check around in the Nexus 7 original development section. Look for Wuggs.

I looked at his toolkit but it basically says that I have to root in order to even use the toolkit so is there a way to downgrade without having to go through that rooting process? For now, I don't want to root my nexus

Don't try to root it you'll only manage unlocking the boot loader then when you try and root it it will get stuck in fast boot mode I tried about every rooting program but it could be because my Comp is running windows xp lol

It's so easy to just reflash stock and relock the bootloader that you really have nothing to worry about. If you want unrooted stock 4.1.2 just unlock the bootloader, then flash the stock image of 4.1.2, then relock the bootloader after. It's a really simple process.

If i'm not mistaken, as long as you flash back to 4.2.1(which is the os it came with when u got it out of the box), and then re-lock the bootloader, unroot, then your warranty wont be voided mate. hope I helped.

Yeah, I've done this plenty of times with my Nexus 7 and even the Verizon Galaxy Nexus. As long as you're on a stock image with a locked bootloader, they won't give you any trouble or claim you voided your warranty, as there's really no way to tell. I've gotten into the habit of unlocking and rooting my device as soon as I get it, and if I find a problem I just revert back to a stock image, relock the bootloader, then send it back in. I have yet to have a single issue.

You don't need to worry about saving your stock image. The person above you is talking about saving the stock image to return to after flashing a custom ROM.
There is no way to revert back to 4.1.2 without root access. Doing a factory reset, about the only thing you can do without root, will only return you back to stock 4.2.1
My advice just stay on 4.2.1 whatever your issue is with it.
Otherwise use a toolkit. You will need a PC and the 4.1.2 image. Wugfresh has a website. I would start there.

I actually was just referring to the stock images you can get directly from Google or from goo.im. It's easy enough to just use the 4.2.1 stock image from Google to just restore back to how it shipped, and then relock the bootloader.

Completely agree with this... I have, on several occasions, reflashed stock, switching between 4.1.2 and 4.2.1 - (for me, it was more of an exercise in learning about fastboot and adb... and making sure I had TRIED AND TESTED factory images on my laptop as contingencies should anything go wrong when I came to start flashing custom ROMs).
-----
You don't need root to flash a factory image... everything is done with fastboot; with the Nexus 7 in FASTBOOT/BOOTLOADER mode (from complete shutdown, press and hold Volume Down button... whilst holding, press the Power Button).
(Root is meaningless anyway, here in FASTBOOT/BOOTLOADER mode, since /dev/block/mmcblk0p3, the SYSTEM partition, hasn't even been mounted yet - so no SU binary available... whether or not it exists, it's sort of irrelevant).
- here, for example, is the flash-all script from 4.1.2 (nakasi-jzo54k)... (Nexus 7, WiFi model only).
Code:
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot flash bootloader bootloader-grouper-3.41.img
fastboot reboot bootloader
sleep 10
fastboot -w update image-nakasi-jzo54k.zip
After running this script (flash-all.bat if in Windows, or flash-all.sh if an Apple user) you can optionally choose to lock the bootloader with... (if you're concerned about warranty issues).
Code:
fastboot oem lock
-----
If it was the case you needed root to run...
Code:
fastboot flash [partition to be flashed] [IMG file to flash]
...you wouldn't be able to flash a CUSTOM RECOVERY like CWM or TWRP... and thus, you wouldn't be able to flash Chainfire's UPDATE-SuperSU-v1.00.zip (http://download.chainfire.eu/310/SuperSU/UPDATE-SuperSU-v1.04.zip) in order to gain root in the first place!... (you see the paradox!).

No you're fine. I just got mine yesterday and naturally the first thing I did was update. The steps to unlock the bootloader and flash a recovery (or SuperSU, if you want root on stock ROM) are the same regardless of Android version.
EDIT: Also you DON'T NEED TO ROOT to use ROMs—all ROMs come with root already built in. Skip everything to do with rooting, unless you're trying to root and stay on the stock ROM.
All you need is to unlock the bootloader (ridiculously easy) and flash a custom recovery (also super easy). Then, without root, use the custom recovery to wipe and flash your ROM (which has root built in) and gapps.
