Is there a way to update to the latest version 4 with unlocked bootloader? I dont really care if I loose the root or not. The last time I tried to switch to stock from my rooted .145 and update from the phone, my phone "brick" on me. Luckily there is a way to fix the problem.

No, I haven't. I have locked bootloader(yet). But read about it in some threads. Is this just an offer from me... Read the comments.
Ok finally after several research and try I find the following are the easiest method of getting root on the latest version (for people with unlock bootloader).
1. Flash using Flashtool any unrooted version 4 ROM
I used the following: http://forum.xda-developers.com/showthread.php?t=1209237
2. Switch off your phone, and boot into fastboot mode. How? When the phone is off, hold the menu button and connect the USB cable to the PC.
3. Using fastboot command, flash the boot image created by Doomlord. Here is the link: http://forum.xda-developers.com/showthread.php?t=1172885
4. Boot your phone, and enjoy the rooted ARC
Yes kuailan thats the same method I used. Its not just a rooted arc now, with setcpu app you can under/overclock it, and i dunno if any other addons.
Anyway, remind yourself and everyone that once its in that state, never do OTA update as doing that on a bootloader unlocked phone will result in bricked phone. Its recoverable, but requires additional effort. So there's the warning.
Installation Steps (Warranty can be restored whenever you wish)
-------------------------
Before starting your rom flashing journey it is always better to have Flashtool (latest -by androxyde) installed in your PC and your stock rom handy ; incase of any mishappenings.
Type *#*#7378423#*#* in your phone and see if your bootloader status is unlockable under service-->Configuration. Procede with below steps, only if your device is unlockable.
It is important that you follow the steps in order
1) First step for installing a custom rom over a mobile with stock rom is to backup the existing state of bootloader .Usually warranty will get void if any modification is done to bootloader. The below tool ensures that it takes the backup of existing state of bootloader when device is under warranty.
Goto
Backup TA for Sony Xperia (This tool helps you to have a )
http://forum.xda-developers.com/showthread.php?t=2292598.
Download the tool.This tool will backup your DRM Securtiy keys . Successful backup can only be taken after the existing stock rom is rooted (Use towelroot application if your device is not already rooted) .Root it first then follow the process given in above link .
Once this is over , u will have a backup of the existing state of bootloader/TA partition (If you later wish to move back to stock rom from custom rom use the same tool to restore the backup you have just created.This means you will get your Warranty back);
2) Goto this website , follow the steps and get your unlock code via e mail.
Use fastboot mode to unlock your bootloader (Make sure that you have already backuped your existing DRM keys-Step 1).Follow it fully to unlock your bootloader
http://unlockbootloader.sonymobile.com/unlock/step1
3)Download any custom rom zips with recovery, for your mobile from xda developers forum and have fun.Extract boot.img using winrar or winzip .
Flash boot.img via fastboot mode
fastboot flash boot boot.img
fastboot reboot
4)As the device reboots, when you see your LED glow press volume up or down. It will take you to CWM Recovery or TWRP recovery based on the rom that you have downloaded.
5)Just install the custom rom(*.zip ) from within the recovery.
What if that i already have the custom recovery?
So, just wipe data, dalvik, and cache, then flash the zip?
That's it?

Absolutely right. But before installing an custom rom in the first place i hope you have already backed up your DRM keys for warranty purpose(as mentioned in the guide) since if you unlock your bootloader without backing up your DRM keys, DRM keys might be lost forever .

Sure. Easiest way to do it is by using an app called, 'Titanium Backup Pro'.But you have to root your stock rom first for this application to run(Use towelroot if you are yet to root).Except for sony proprietary apps like walkman,Album,etc (will run only on stock rom as they use sony developed system libraries/API'S) other apps will get restored/run fine on a custom rom.

its in the OP....on the phones dialpad, type: *#*#7378423#*#*
then look in > service > configuration
it should show the status as "bootloader locked", "bootloader unlocked", "bootloader unlockable" or "not unlockable" (sorry wording may not be exact, but you'll get the idea)

no.. i mean, how to know if my bootloader is already unlocked or not?
Anyway, what happened if i flash it without unlocking it first?
Sorry, did you type that in the phone and check the status? That's where it will tell you if its already unlocked or if its even unlockable at all.
Do not try to install a custom ROM on your phone if it is not unlocked! Your phone will not boot.

Thanks to @ foomanjackel for answering your questions.Regarding your 2nd question, 'Experience is the mother of invention'.Why don't you try and see what happens...just kidding.Couldn't resist it. Practically speaking of you install a custom rom with an custom kernel on a locked bootloader you will hard brick it.It will not boot and chances are that you might not be able to goto flashmode or fastbootmode anymoreto repair it.Reason this happens is that both your recovery and bootloader resides in the same partition in your mobile.If you try to install custom kernel on a locked bootloader in every probability, it not only corrupts your existing stocks kernel but also might corrupt your recovery leaving u helpless.
Theoretically, You should be able to install any custom-stock based rom on a locked bootloader (which runs exactly on ur stock kernel).In other words a custom rom which doesn't come up with a custom kernel but based on your existing stock kernel should be able to run on a locked bootloader.But my advice is you do not risk it.

If you get this message "Bootloader unlockable: yes" then your bootloader is still locked.

if you're returning it to Google they don't really care if it's locked or not. I've sent them back for an RMA both ways never had any problems
Agree, relocking shouldn't be needed for a RMA...
Just make sure your device is completely stock at the very least.
Personally, I'd flash the factory images to both slots and lock the bootloader. However, if others have suggested they don't have any issues sending it back with the bootloader unlocked, then just flash the factory images.
Although, it is just one command to lock it (just be absolutely sure you're completely stock before locking, if you go that route).
thank you All! but i need to get the stock recovery... how can i install the Stock recovery without an pc and without twrp? because i have the twrp edition with the encryption problem on Android pie... ??

You could download the OTA zip and move it to your data folder with a root explorer type app, then flash it with twrp. Will twrp not decrypt without screen lock security?

That's exactly why I never unlock the bootloader, root, install custom ROMs, etc. I don't want to be in the situation where I can't use my warranty or insurance.

My bootloader was unlocked and it was not an issue. I sent my phone back and got a new phone in 6 days. I guess it would also depend on where you live. I live on the east coast and sent my phone to Texas and they sent me a new one from Illinois.
Hello, I am wondering if I can flash the stock boot.img again to de-root my device in case I want to go back. Is it also possible to reflash the entire stock rom again from fastboot? If not how would I go about doing that.

Yes flashing the original unpatched boot.img will unroot.
If you made any changes while rooted, they will remain and may cause issues,

Thank you for your quick response.
unrelated question, but I also plan on porting TWRP onto this phone too. Is there any chance of bricking my phone if I were to boot up a custom recovery from fastboot, not flash, but BOOT it? If its incompatible would it just default back into fastboot or something like that?

Arobase40 said:
I experimented this no touch TWRP but it is mostly buggy excluding the non touch issue there is a bigger issue which is that once installed you can't get out from it as it bootloops into this recovery mode. Flashing a stock recovery won't change anything.
You will have to totally restock your phone from scratch and then re root it and restore all your apps and data !!! ^^
I found out the twrp tree for A52 4G and was able to build a TWRP but obviously I can't test it.
I'm not able to build a twrp for A52S 5G for now as there are missing many kernel modules and other stuffs so I have to build them from kernel source code. So for now I'm working on the device and vendor config files...

Unfortunately, I have tried to reinstall stock firmware, but it failed. Looks like my bootloader became locked. Odin software showed "FAIL". There was a message that I could barely read, so that was the reason it failed to reinstall the firmware.

So you got stuck in a bootloop after installing twrp. Have you tried just extracting the stock boot.img from firmware AP file and flashing it with odin? I really don't get it why you had to reinstall everything to stock. It's not necessary to reflash every partition if you only messed up one

While the phone is completely off, press vol up and vol down buttons at the same time and then plug in the usb cable to the computer. I had that happen too, when the device fails to boot it automatically puts you into download mode and it says that the OEM LOCK is on. You just have to reboot to download mode manually.

You don't need to unlock bootloader to flash stock fw with Odin.
Your problem is most likely related to something else.
Where did you download your fw?
Have you tried different cables?
What Odin version are you trying?

A Locked bootloader will prevent you from installing any custom things, like recovery or custom roms. It will allow you to install stock firmware via odin. Use Odin 3.14 to install firmware downloaded from here. Use the AP, Bl, Cp, and CSC_OXM files. That will get you started from scratch, all previous data and stuff will be deleted.
