[Q] How do I get root back after update to .62 firmware?

I just updated my arc via PC companion software to .62 firmware.
I rooted it earlier by super one click method by DooMLorD from here.
Now after the update I don't have root access and I can't get it back by the same way or by GingerBreak and I can still see superuser icon.
The system apps are reaaally using too much memory.
Any idea how i can solve that please?!

using flash tool and a .42 FTF downgrade from .62 to .42 un check wipe cash and wipe user data and you save everything.
root using flashtool
do an OTA update to .62 and you remain root.
then and only then can you delete system apps you dont want. if you change the system aps befor the OTA update it will fail to update.

What needs to be done in the following ORDER
1 - Get yourself a firmware (whichever one you want) .42
1.1 - Connect your phone to your computer
2 - Using the application called Flashtool which be can be found on the forum (multiple threads) Flash the the rom. You will loose all your contacts, sms etc...
2.2 - Wait for the tool to tell you that it's done flashing
2.3 - Using ZergRush or Flashtool ROOT your phone.
3 - Start your phone and disconnect it from the PC
4 - Press the menu button and go to SETTINGS - ABOUT PHONE - SOFTWARE UPDATE
5 - This will verify and push the OTA for .62 to your phone.
That's pretty much it in the simplest way possible.

it`s not so easy
I did it exactly step by step,
phone shows information about upgrade but what i need is PC Companion to do that. This information is in notification about new firmware.
ok I did it but first I had flashed LT15i_4.0.2.A.0.58_Generic Global HK because only after that I could upgrade withouth PC Companion.
thx for advice.

Yeah that was point 1. Which was to get yourself a firmware version .42... then yeah you can update via OTA...

I can't update .42 OTA it is possible only when i flash .58 first...

How about if I'm already on firmware .42 rooted with locked Bootloader, can I update to .62 OTA and still have root?

I still have a small question about this.
Would I still be able to update OTA (from France) with .42 World or shall I use a .42 France ?

That's what I have done, and worked well.

Question: How can I update via OTA? Is there a site like wotanserver or something? Or is OTA an app I can download somewhere?
I updated my WT19 with PC Companion, it has .62 firmware now, but I need root to delete system apps and clear space on internal memory.
Anyway I always update via wotanserver, because I can't find the .ftf I need to flash it via flashtool. And now I'm having problems with wotanserver, so where can I find those firmware files (ftf) ?? (for my model)

When installing 4.0.2.A.0.62 it says can not install

I have the phone rooted and when I try updating to 4.0.2.A.0.62 it just says can't install. Do I have to flash it all over again, which would mean loosing all apps?

Via OTA?
Better leave it as it is.
Update via computer will remove root.
Data remains with both methods.
Sent from my iPad 2 using Tapatalk

happened to me too! You have to flash .42 again, root before u do anything else and right after root update via OTA! ;-)

And if you don't wanna do it again next time, backup your applications right after OTA update, so you can restore it for the next OTA update (if any)

Is it not possible to unroot, and then update to 4.0.2.A.0.62 ?

Rooting the phone doesn't prevent the OTA update, messing with system apps does. (And you usually mess with system apps when rooted)

Ahh of course.. Iv'e deleted a few system apps and messed with other things (crapware)

When you put them back, you can update your firmware. When you do it OTA, you will keep your root.
Furtermore, this update won't remove any data or apps.

What should I use for backup?

Titanium backup will do, and by the way, if you find your current firmware you can try and restore one by one the bloatware you deleted or restoring any mod you have installed, I did this and I was able to update via OTA again.

It doesn't work. I flashed
LT15i 4.0.2.A.0.42 Generic Global World (EASY ROOT WITH FLASHTOOLS): http://uploaded.to/file/vmfu4czg
Used flashtools to root right away, still says can't update.

You may consider either retrying (some people reported having to flash twice or thrice before it would work) or using another firmware, or using a different flash software (I did updated OTA after flashing .42 with wotanclient).

I experience this. What I did I reflash with rootable firmware then root with flashtool without removing any app then I directly update OTA. Then I successfully install.

I have similar problem and now I have a rooted .62 NAM firmware.
What I did is the following:
Flash your phone to .42 firmware with flashtools
Update your phone to .62 with PC companion
Re-flash your phone back to .42 with flashtools
Root your phone with flashtools
Update your phone to .62 with OTA

No need for step 2, 3 and 4!
Sent from my LT15i using XDA App

Just have a rooted .42 firmware with an locked bootloader ( i seriously doubt that you have a locked boot loader )
Aftet that just update to .62 over the air [OTA]
If this doesn't works then either flash a pre rooted .62 firmware via fastboot or flash a fresh unrooted firmware via flashtool and then root it by recovery method! If you still have a problem then PM me!

So you never tried doing the stuff without step 2,3 and 4?? It will work for sure....cause there are only two ways (till now)to have a rooted .62 as stated in my previous post!
But you can guide someone with your method if the original two doesnt work!

I havent gone through all the posts of this thread but i think that the guy aint asking how to have a rooted .62 (incase he is then plenty of threads for it and me and my fellow members have also posted about it here)
Hes just having problem in updating via pc companion.....and the only solution i have is relocking the bootloader, i know i keep asking to lock the bootloader but thats the key to it!
If i missed any point here and please feel free to let me know! ;-)

Since you are using fastboot i assume you got an unlocked boot loader. So here is a easy way to root .62
And in case you are done with it and want to have recovry on stock kernel then you should install CWM AUTO INSTALLER from market/play store. Just follow the instructions after running the app! If you have any problem you can drop a question here or in the thread i suggested you!

Since you dont want to unlock your bootloader...you got to follow the OTA stuff.
Here is what you gonna need...
A fresh .42 firmware, flashtools. You can get the stuff from here http://forum.xda-developers.com/showthread.php?t=1330314
Now,
1. Flash the .42 firmware with flashtools
2. Root it with flashtools (the above thread tells you how to)
3. Update your phone over the air.
F.A.Q.
Q. I already have a rooted .42, why should i flash it again and then have root acess?
A. Most of the users uninstall the bloatware or other stock based stuff and then they face problems during updating the phone OTA. Hence to be on the safer side...its advised to flash the .42 firmware and root it again.

Thanks, ArcMan09. I have only rooted the Arc and have not installed any other firmware - it still has the existing manufacturer's firmware. I have also not unlocked the bootloader. Will it not accept an "official" update again ?

The updates do some checks on your current system, if it seems modified it will not update. Just do a restore in pcc it will install the latest version on your phone for you.

Just flash 4.1.A.0.562 ftf files with FlashTool.
FlashTool do not require unlocked bootloader.
After that you can root easily.

I just updated my Arc to ICS. Connected through the Sony Companion which detected the SW update and it downloaded and updated it. The downside of this is that my existing root has been 'patched', ie, it has been unrooted with the update. Waiting for Doomlord to work his magic now

Yes - but what we really need is a 1-click rather than flash 'down', root and then flash. Am too lazy for these you know...basically a zergrush exploit or an emulator trick for the latest firmare...

There is no easy root method at the moment. If you want root then you will need to downgrade the kernel then root then update kernel.
Sent from my LT15i using xda premium

The only easy way is an unlocked bootloader, other you'll either have to use the downgrade or wait for an exploit.

Step 4. Root using http://forum.xda-developers.com/showthread.php?t=1601038
Step 5. Download the .431 kernel
Step 6. Flash .431 kernel and reboot phone

I don't see why you need to go check on the talk.sonymobile.com site as those very same instructions have been posted here.
You do realise that everything that happens there is just a rehash of what happens here at XDA. :cyclops:

True...just that I had several links bookmarked on this rooting thing and I followed one of them. Btw, the .562 & .431 kernel links were about 5 MB each, whereas the ones I found on XDA were ~250MB - guess they included the entire stuff...or, I wasn't searching properly here:crying:

Righto...just wondering why you need to download the whole ftf's when kernel flash would do...

Probably because they couldn't find the kernel alone. In that case, the only option would be to download the entire ftf.

Deny that update, and wait for OTA update, OTA updates doesn't affect root.
It was like that with my old arc, with my wife's xperia S, and its like that with my Ion too.

Thank you very much for your help
So i have to wait till Bin4ry will update his root tool so that i can use it with my Sony Xperia S locked bootlader 6.1.A.2.55

if som1 would new if this tool comes out and can root 6.1.A.2.55 i would be very nice if he/she could tell me that

AFAIK the only method to root .55 was just bin4ry method done before updating..
so, you won't loose your root (as far as you don't wipe data/system)

I have not lost root anytime I did an OTA update. If you have made system file changes though OTA won't work.

SUS will remove root.
The backup & restore app will only put back apps and app data. You can always use flashtools to restore to .50
