Different Firmware- can I still root?

I would like to root My LT18i Xperia Arc S, just so I can get rid of the bloatware, although if I could upgrade to ICS as well then that would be cool. I've found loads of instructions on how to root, but none for my firmware version, which is 4.0.2.C.0.5. The phone is locked to Three (a UK network operator). A lot of the instructions talk of downgrading the firmware from various versions to 4.0.2.A.0.42, and then rooting from there, although none list my particular firmware. Is this method possible for my firmware version? If it's not and I try anyway will I wreck my phone? I'd like to be as sure as possible before I start. My boot loader is locked.
Thank you.

Have you run SEUS or PC Companion at all? There's been 5 FW releases since then according to Wotan Server.

From what I have heard, the regular root method for GB, 4.0.2.A.0.58 and lower, should work also on 4.0.2.C.0.5 firmware. Give it a try, you got nothing to lose there.

OK, so I really am a total numpty, I was assuming that all updates could come OTA, and because I didn't have any updates available when I checked on the phone I must have the latest version, I hadn't realised that updating it from a PC did a full update. :silly:
So I'm now updated to ICS, although in a way my original question remains... Now my build number is 4.1.L.0.8, so can I follow the root guides for 4.1.A.0.562, for example the guide here: androidauthority.com/xperia-arc-s-lt18i-root-android-4-0-ics-80266 ? And equally importantly, if I try to follow the guide and it doesn't work on my firmware will it simply do nothing, or will it wreck the phone?
Thank you guys, I thought I had done a lot of reading up on rooting and flashing and unlocking boot loaders, but missed the obvious and a simple comment like "Have you tried SEUS" can make all the difference!

If it doesnt work, your phone should be fine. But that also means that you've been doing something wrong. Give it a go
Sent from Xperia Arc S

I followed the instructions here for rooting:
http://forum.xda-developers.com/showthread.php?t=1601038&nocache=1
It seemed to go through all the stages, the phone rebooted several times and it came up "All done" at the end. The good news is that the phone still works fine, the bad news is that it doesn't seem to be rooted. I've installed Titanium Backup and it comes up with "could not acquire root privileges, please check that your phone is rooted", so I assume this means it hasn't worked? Is there any other way to see if it's rooted? This is the output from running the rooting batch script:

There's four links to root threads now in my guide, give them a read.

Thanks, that guide was very useful. I've actually used a combination of the techniques, and it seems to have worked Here's what I did, might be useful to someone, also please if anyone who knows better than me can see any problems then please let me know if I'm going to have problems in the future
1. Backed up my firmware using the instructions from 100rabh791 here:
http://talk.sonymobile.com/message/178992
2. Flashed back to 4.1.A.0.562 Kernel using Nabeel's instructions here:
http://talk.sonymobile.com/thread/41119?start=0&tstart=0
3. Rooted using DooMLoRD's root kit here:
http://forum.xda-developers.com/showthread.php?t=1601038
At this point I seemed to have a fully working and rooted phone, however I thought it was best to go back to my original build version (4.1.L.0.8), so I re-flashed my backed up firmware, However this lost my root privileges, so I was back to the start. So I re-did steps 1-3 and then:
4. Re-flashed back to my original firmware, but checked the options "Exclude system", "Exclude baseband", "Exclude Fota" and "Exclude TA" (in other words just left Kernel unchecked).
So as I understand it (which I possibly don't), I should be back on my original, most up to date build version, but now have root access, please correct me if there's anything wrong with what I've done.

Nice one, doesn't look like you'll have any issues, but the main thing is you've got root. What does it say in your Settings/About Phone/Build Number?

4.1.L.0.8 which is what it was on after the official upgrades before I started the rooting process.

i have a question when i press Volume Up, Power, Menu buttons

it takes me to android recovery, i noticed theres a option that says apply update from sd card,
if i put the super user zip to my sd card will it root it? i dont want to brick it though! any suggestions?
please help!

well i just tried installing superuser zip that i got from here http://galaxys3root.com/galaxy-s3-root/how-to-root-galaxy-s3-on-mac-osx/
and it said signature verification failed. hmmm

Need custom recovery to flash that.

damn i got all happy for a seconds thinking i can root my s3 without using my mac!!!
:crying: still unable to root! damn you jellybean! hahaha
is downgrading to ics to root s3 troublesome?

Use the methods that are stickied. Can HARDLY ever go wrong there. I say hardly cause some forums for older phones are not up to date, these are.

I don't have a mac so I don't have the issues obviously but did you do what it said to do? Go to play store and install Super SU just to test? also, can you not use ODIN? Since no one else is helping I figured I would jump in and spit ball ideas.

ADB not working

Hi, I just got my replacement S3 and I am attempting to root it. I've tried doing it on my own and with toolkits but nothing seems to work.
When putting the phone in debugging mode it technically won't go in. The little jellybean guy no longer shows up on the top and it says connected as a media device but 5 times out of 10 it will show up in ./adb devices.
I am attempting to transfer the root files but every time it gives me permission denied, what can I do?

Try uninstalling your Samung USB drivers and installing the most up to date ones instead. If they are up to date try doing that anyway. Also make sure your using your factory cable. And lastly try another USB port on or PC or another PC all together

I'm using a mac. Everything worked with the old device

I had trouble with this also. My replacement phone had Jelly Bean.
I just put it into Download mode and flashed a rooted stock ROM instead.

Just tried that but the device doesn't show up in adb in download mode. Why is this so hard? My first phone was a 1-2 thing.

Why are you using ADB in download mode?
Use Odin.

I'm trying everything I can.
I have a windows/mac machine. The device doesn't show up on the PC (drivers/kies both installed) but it does in my mac but I get the permission denied errors for everything as mentioned in OP.

Sounds like ADB is requesting super user permissions from or Mac. Or best bet would be Odin on a PC. See if it sees the device. If it doesn't try it with debugging on and off

[Q] Rooting problems - Please help!

Hello everyone,
I've had my LG Nitro HD for about a year and a half. I've recently been disappointed with it's performance and battery live. I read rooting and adding a new rom really helps free up the phone's natural performance. I've unlocked a few phones in the past. This one seems to be giving me a lot of fits.
I downloaded a zip file called 'P930_v20e_ROOT". I do not want to share any external linking as it's usually frowned upon. Nevertheless I unzipped the folder and copied the file "LG_SystemBackupTest" to the root of my sd card. I downloaded a file manager app to execute the file. Once installed I enabled the option for unverified sources, and the option for USB under development mode. I also installed the OEM LG driver off of their website for the P930 model phone. I then ran the LG_SystemBackupTest file that was in my applications. While it ran it simply states "hello world". I powered off/restarted the phone as instructed.
Once the phone booted up I plugged in the usb cable to my Windows 8 PC. I then ran the "root_p880" file. Below is the error I get repeatedly.
DON'T TOUCH THE DEVICE OR UNPLUG WHILE ROOTING!

I've tried every possible combination I can think of. I even booted up one of my old Windows XP machines, performed all the steps above, and still the same. Just now I finally reset the phone to it's factory defaults. Only to get the same results. Can anyone provide any guidance?
Kind regards,
Jeremy

Just getting root isn't going to allow you to flash a new or custom rom. You need to install cwm using the P930 unbricking guide.

Thank you for the prompt reply. I do have another guide I was following to install a custom rom. However it states I first need to root. It provided no instructions and stated to google how to do it.

You need to go into root admin.
Use the command "Su" to get into root shell

Hi, thanks I've tried that and get the same issues?

After su command was sent through ADB, have you granted access on the pop up screen that appears at first use?
- Reset (unplug and plug back in) unit
- let it boot into main menue
- connect through ABD
- at adb shell prompt type su
- enter
- A pop up screen should appear on your TV asking you to grant access for su
- using your FireTV remote select yes and press OK.
- see if issue is solved

so you used this guide http://www.aftvnews.com/how-to-root...covery-and-a-pre-rooted-rom-all-without-a-pc/ with your rooted Fire Tv2?

i used this guide http://www.aftvnews.com/how-to-root-the-fire-tv-2-using-kingroot-no-usb-cable-required/. but at the time if i remember i updated my box to stock update 5.0.5 from 5.0.4 then rooted again.

Hi, the trick is to use this Guide http://www.aftvnews.com/how-to-root-the-amazon-fire-tv-2/
Worked perfectly

I know this is an old thread but I'll post what worked for me just in case...
On ADBLink, select Root → Mount /system RW. This will make /system writable.
Not sure if this is necessary, but I switch back to RO (read only) once I was done with my changes.
