[Q] how to update with unlocked bootloader?

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.

[Q] nAa-r2 recovery CWM + SE TWEAKED v0.7 = Possible?

in the thread of nAa-r2 CWM for mini/pro/active/arc it say you can install stock rom in the recovery, and i searched for stock rom and i bumped into SE tweaked thread and i am confused if this are compatible. is SE TWEAKED really a stock rom? and one thing SE tweaked thread says that the requirement is unlocked bootloader, mine is still locked but i have fastboot and cwm.. what does that mean? enlighten me please.. thanks..
i think i also need a list of tweaked stock roms that can be use from nAa-r2 CWM..
thanks in advance to all who will answer my query.. ^_^

You can use that recovery on custom kernels/ROMs too.

no kidding?
wow.. but it says will only work on unlock bootloader.. mine is locked..
i just want to make sure that it will brick my phone..
this will be an expensive paper weight if that happens..

I've had a locked BL and that CWM recovery installed.
Then I unlocked my BL, flashed a kernel and the recovery and the backups where still there.

my bootloader is still locked.. i want to know if i can flash it even though it is still locked.. i still have no plans of unlocking my bootloader.. maybe i have to wait a little more before i can decide of unlocking it.. i am not worrying about losing my recovery, i am concern of bricking my phone..

Yes, you can flash it even with locked BL.
Look for the program in this thread:

[Q] Unlocking bootloader & flashing new kernel = brick?

Hi everyone,
I've got a quick bootloader unlocking query - if I were to unlock my bootloader and then immediately flash a custom kernel (i.e. no reboot in between), would this cause a hard-brick?
I ask because I'm on my 2nd phone now, having bricked the first one due to impatience! I'd like to unlock the bootloader but I'm too scared of bricking it again :silly:
Cheers

im quite sure you may need to let it settle for a bit
there has been no one who i know of who has done that so id suggest of unlocking and waiting a day or two
Sent from my LT26i using XDA Premium 4 mobile app

I think you'd better read carefully in the furom,unless you are full understanding,you can flash the custom rom
Sent from my Xperia S using XDA Premium 4 mobile app

Yeah I've done a lot of reading & following guides for rooting etc. I've been searching through the bricked devices threads and it has now put me off unlocking the BL :laugh:
I found this post (http://forum.xda-developers.com/showthread.php?p=48773344#post48773344) where someone has successfully unlocked their bootloader and flashed an advanced stock kernel, and then flashed the DooMKernel (same one I tried the first time) and then bricked their phone!! Their symptoms are exactly the same as mine. The annoying thing is that everyone else seems to be able to flash the DooMKernel without issue - the DooMKernel thread is full of satisfied customers! The randomness of bricking isn't worth the risk
Cheers guys

well, this is my person experience, i unlocked and loaded a custom ROM immediately without flashing the kernal and it works fine. I am not sure if flashing a kernel after that will create any issues.

If you flashed a custom rom that required an unlocked bootloader, then I assume it's because it comes with a custom (i.e. non-stock) kernel? After unlocking the bootloader, did you let the phone boot normally before flashing the custom rom?

Yes I did... I asked the custom rom had a custom kernel inside

Ah, so you managed to flash a custom rom/kernel without rebooting after unlocking the bootloader? At least that confirms that something else is responsible for bricking my phone. When I bricked my phone, I didn't wipe cache or dalvik - I started from a fresh stock rom...didn't even root or have a recovery installed.

[Q] How to be sure that Bootloader is Unlocked, still receiving OTA updates

Hi I am a newbie. I had rooted my phone using Towel-root method and am even using xposed framework and am running stock version. After this to Unlock my Bootloader I fallowed procedures as given by sony, but after i entered unlock command in cmd, my xpeira m went into bootloop.
I tried repaing usning pc companion it said that my mobile has been modified and cant repair, and hence using flashtool flashed stock xperia m rom and had to root again.
But the problem is that I still receive OTA updates from Sony for Walkman and album apps. If my booloader is unlocked I shouldn't be recieving those right ? How can I confirm for sure without flashing anything ?
Another question: Now If i flash CWM from here http://forum.xda-developers.com/xpe...ery-philz-touch-6-41-6-xm-dual-t2795778/page2 will that erase my rom ? I mean do I have to flash my stock rom and reroot after flashing CWM for my device to work ?

i think i have an answer

Hi raghu,
see answer to ur first question, i dont think bootloader status will effect ur updates , because at first i tried to install CWM and went into bootloop , before that i unlocked my bootloader using flashtool, so i flashed .ftf file and went back to stock , when i tried to flash CWM i noticed that my bootloader was still unlocked , flashing .ftf didnt change it at all. i dont know whether this happened to me accidentally or it will really doesnt effect ur bootloader status but the answer is bootloader status will not effect ur updats ( as far as i knw).
answer to ur 2nd question is no it wont erase ( i am sure about it :good ur current ROM, if u flash it right. Dont worry i tried that recovery before, its gud and flash carefully, dont end up into bootloop once again ..safe flashing
thnx :good::good:

Your device's bootloader is absolutely locked if you are still receiving the OTA updates (and installing ). And I would suggest you to check the Bootloader status in Flashtool.
No flashing the CWM will not affect your current ROM

https://www.dropbox.com/s/ncyza0776myusll/Capture.PNG?dl=0
connect ur phone in flashmode and click on the BLU icon , then it will automatically get the code for ur IMEI and all u need to do is click Unlock and if u flash CWM on locked bootloader it wont work and u may end up in bootloop ( nt sure abt that coz never tried till nw )
hit thanks if this helps.:good::good::good:
hope this helps ,

As far as I am aware only the OTA firmware updates no longer work when you unlock your bootloader, the OTA application updates should work as intended.
For installing the kernel, all you have to do is put your device into fastboot mode, select the kernel with flashtool and then let flashtool work its magic. It won't wipe your ROM as it doesn't touch the /system partition.
You don't even need flashtool to check your bootloader unlock status either. Type in *#*#7378423#*#*, tap Service info, tap Configuration. You will see a section what says rooting status. Underneath rooting status you will find your bootloader status, it will read one of three things;
1) Bootloader unlock allowed: No (meaning you cannot unlock your bootloader, you shouldn't see this as you have unlocked yours by the sounds of the first post)
2) Bootloader unlock allowed: Yes (meaning you can unlock your bootloader, if it says this and you plan on unlocking the bootloader I hope you make backups of your TA partition cause you have no way of locking your bootloader again else. This goes for anybody reading this)
2) Bootloader unlock: Yes (meaning your bootloader is unlocked).

the bootloader isn't unlocked(ever) we just use a workaround , you need to revert to kitkat first for this to work and you can install twrp by following the instructions HERE

this method requires you to downgrade(only bootloader) and is more dangerous then the regular downgrading approach. just downgrade you could enjoy have enjoyed a rom by now(while you were searching for the correct images
