So folks.
Just reached home with my new phone, an Xperia Arc S LT18a, I believe.
I'm stuck with this firmware 4.0.2.A.0.62 which doesn't seem to have an easy way to get a custom ROM on it yet. Sucks that I didn't read about this before heading out to buy a phone.
I went through one of the guides here and had the bootloader unlocked via Sony's website. However, the rooting instructions didn't work. So searched further and realised the issue.
I've seen people say that they've done it by downgrading to a lower firmware, rooting it and then upgrading the firmware OTA again. Then I read that upgrading firmware OTA with an unlocked bootloader will brick my phone. So I'm not trying that.
Any help on how I could go about this? Simple step by step instructions would be very welcomed, since I don't really know much about flashing various bootloaders and ROMs considering I just bought the phone.
Thanks for reading!
there are many threads relating to this problem....plz read & search before posting....
Well i believe the answer to your questions lie in this Thread ...

Flash the zip I attached to this post through CWM. That's it, you're rooted
Thanks!
I used the above zip file, but from a different thread and got it working. Cheers to both of you!

How can I have CWM on my phone? If I will flash phone I will do it with rooted ROM not stock. For me it's closed circle because I need root'ed device to load CWM on it, and I need CWM to make root.
Can someone explain me it?

With unlocked bootloader, one can easily flash a custom kernel with CWM, then flash the zip file.

I when I rooted my locked bootloader ARC S, I read "The Nutshell Arc Guide" at http://forum.xda-developers.com/showthread.php?t=1304634
Before you start messing with the phone, please see the entire guide first.
Hope I can helped.

Hi all
Ok it's a long story but I think you guys need to know.
Ok I've got a arc s which isn't rooted and bootloader is locked (i think), running the latest stock rom.
I want to get a different rom like CM9 or CM10 because stock rom is almost unusable but I need to unlock my bootloader and root my phone, but everything I try to do those 2 things just fail for some unknown reason.
I have no idea if the latest stock rom is rootable yet, but I've red up that you don't need to be rooted to unlock the bootloader
( I'm not 100% sure on that).
But when I try to unlock my bootloader my phone won't boot into fastboot mode, (I know how to do it but it just goes into the charging screen).
and when I try to root my phone the program i used just gives me a ton of errors and phone isn't rooted when it's finished.
( I used doomloards ICS rooting method )
So I question is
Is there any rom I could flash in my phones current state because I HATE stock rom, I just can't use it without it rebooting all the time.
If so please post a like to the rom
Any help will be appreciated.
Read the stickies, look in the development section.

Install CWM and flash a Rom for locked bootloaders (eg. JJ`s Hybrid Rom )
P.s. : Have you checked if your botloader is unlockable ? Have you tried to unlock it at sony website ?
And if you realy want to unlock BL and root your phone... do some more reading. You will find at sony website all the info you need to know about how to unlock your bootloader. From there it should be very easy to flash custom kernel and Rom (custom kernel comes with CWM integrated).
Ok well I've looked a bit more at sony's website and found the unlocking bootloader page http://unlockbootloader.sonymobile.com/instructions
But when I entered the code in the dialler, nothing happened...
Also I've found this thread http://forum.xda-developers.com/showthread.php?t=1642480 which looks useful enough but I follows the thread to the rooting pages
and I looked at them they where the same methods I tried before, but it doesn't work, I just get errors and no root
I've had this problem before, when I was trying to root my phone, It just kept failing.
I saw some threads on installing CWM but they all seemed to require root access. so at the moment I'm ******.....

But it just gives me errors and not rooting it.
Hi all, im a newbie here, i bought my Xperia PRO a month ago, and rooted it on Android 4, using a great tutorial in this forum and thanks to other members i got it right and rooted it in my 4 first days of use. But, i now want to upgrade to a Custom ROM and use a custom kernel , to get my phone to a new generation.
And my question now is, how can i flash a Custom ROM (i was thinking of CM9 stable when it comes out), and flash a custom Kernel with it (i was thinking of Ultima V1.4) and then keep my old applications, or most of them.
I have CWM Recovery 5.5.0.4 installed using X-Parts , and also Titanium Backup Pro . My Bootloader is still locked and i have flashtool and all drivers for my phone installed on my PC.
I would be very thankful to anyone that is able to help me do all these, or if needed, recommend me a better Custom ROM and Kernel, and then explain how i can O/C my phone too, and keep if possible most of my apps.
Also, please tell me if i have to install anything else, or if im missing anything.
Thanks in advance.
Hi mate,
First of all, I take it that you know that you have to unlock your boot loader to install custom kernels and some custom rom's. Like CM9 and 10.
ROM Install Instructions
There are normally instructions that are in the first or second post that explain how to install. If there aren't any, I've copied the instructions from maxio1998, so all credits go to him:
1. Download .zip file and place it on SD card
2. Download and flash kernel you like (or not, if you have locked bootloader)
3. Download WiFi Modules of chosen kernel and place them on sdcard
4. Go to CWM Recovery.
5. Wipe everything! (This means everything but the SD card, or you'll use all you files)
6. Flash zip with ROM
7. Flash zip with WiFi modules
8. In CWM go to "Advance" and fix permissions.
9. Reboot and enjoy [~xDevilCharged~] and PentaPowerful~ Jelly Sandwich!

Kernel Install instructions
To keep it simple, heres a program that doomed151 made. It flashes the .img without having to use command prompt: http://forum.xda-developers.com/showthread.php?t=1551073
Right, onto keeping your apps. As you need to wipe everything to install a new ROM, you can't keep your apps without backing them up. Titanium backup is the best option, and you've bought it, even better :victory: The wipe will not delete the backups from the SD Card so just place them somewhere on there.
You can use any overclocking app from the market as long as you let it use superuser or supersu. Don't recommend passing 1.3, it gets very hot and the cpu will burn out quicker. (Yeah, I know i've overclocked mine to 1.5, but it gets very hot and runs out of battery quickly)
As you've already got CWM installed, you'd be better doing a full nandroid backup, just in case you decide to revert back to stock, you have all your apps installed
Unfortunately, I'm using the arc, so I can't recommend any kernels or ROM's to you. Sorry.
If I've missed anything you need to know, just let me know. I'll try to help
Awesome! Thank you very much my friend, very detailed and nice guide. I'll wait for CM9 stable to be released for my phone an then ill try it out.
Thanks again.
Also, I've searched enough, to believe that cyanogen mods, are the best and most recommended custom ROMs, about the kernel, I aint so sure but ill see what other user's might say.

If i remember right, CM9.1 (stable) has not yet been released for iyokan (MK16i). So that means i have to wait. Also, i can flash a ROM and use a kernel other than the ROM's default one, right? (i want CM9.1 with Ultima V1.4 Kernel)
And one more thing, i have moved all apps to the SD, what will happen to the files there? Will they remain?

I think that you have to use the cm kernel (fxp kernel). Could be wrong though, not really looked into it.
Any apps that you have installed on your phone will be deleted. You have to back them up and then restore them. It doesn't matter where they are installed

so, how can i be sure if it is possible to flash CM9 with Ultima Kernel?
Also, do i have to do anything with google apps? And flash another baseband or something like it?
And last but not least, i have installed CWM using X-Parts, will this affect anything?

Sorry for late reply, just look up the thread again.
Best thing you could do is ask a question the Ultima Kernel thread and hope you get a response. But I think that it will be for stock only, (I think they need different things in them....) but im not a dev, I don't have the patience..... :laugh:
You might have to flash google apps. Just use CWM in the custom kernel you choose. They will be a link in the bottom of the first post to the google apps download.
No need to flash another baseband or owt like that. When you flash the full zip of CM9 in CWM it will add and edit everything you need.
CWM from X-Parts will not have any effect on anything after you flash a different kernel. It will disappear like it was never there.
Hope I'm able to help again Need anything else, just post again, I will pick it up
Good work Jon565G
Not just good, excellent work!
I did it, and flahsed the kernel and all that stuff, now i reinstalled all my apps , and O/Ced at 1.2Ghz , and everything is nice.
But, working on android stuff, makes you want more and more, and as you learn better, that makes you want even more, and now i want to mod another phone.!
I've learned a lot from your help and the help of other members of this forum, and i think i am now ready to "mod" more phone, just for fun.
I already managed to flash an x10 mini with miniCM7 and flash a nAa Kernel, and also flash another x10 mini pro with miniCM7, and probably today ill mod another friend's x10 mini. And later two x8.
Learning, is great, thank you all.
EDIT: I also found out that everything you need is Flashtool, its the best tool out there, it flashes, it installs Busybox, recoveries, it unlocks bootloaders, it roots, it flashes kernels, everything. .Ok you might also need s1tool to check about the semc lock and if you unlocked the bootloader.

I know, I'm the same. I'll want to go and buy about 10 different android devices just to have a play around and mod them. It's always nice to play around with 2 android devices (Please come back in stock Nexus 7 )
Anyway... I'm just glad that I was able to help to introduce you to the world of android modding.
Have fun, that's what it's all about :victory:
(I had to use multiple programs, my bootloader could only be unlocked my test point. Was locked to T-Mobile. Best use of flashtool is when you've bricked it and need to get it back to stock )
I hope you get back your Nexus 7 then
Yeah, i unlocked my Bootloader using testpoint method too, so i wouldnt get any bricks with FOTA updates. And, i also used to be into such electronic stuff.
And, you didnt just introduced me into Android Modding World, you made me a fanatic Android Modder
Anyway, thank you once more, and yeah, thats the point, the fun about all these stuff

well, from what I've read, in ur Xperia u can simply find out the bootloader status by dialing *#*#7378423#*#* service info> configuration
rooting status
bootloader unlock allow:Yes(if locked)
bootloader unlock:yes(if unlocked)
m havin locked bootloader, so do reply with ur status and confirm this to me and evryone else

I am not sure, but i believe, that either you have locked or unlocked bootlader, it will always say "Bootloader Unlock Allowed: Yes , or No if its not allowed).
I aint sure, because in CM9.1 i dial it, and i cant get to the Service Settings, so i cannot be sure.
And, as i've found out, you can be sure if you have locked or unlocked bootloader, by running S1tool, and pressing "IDENTIFY" , which will tell you to connect your phone in flashmode (phone off, connect USB while pressing back) , and it will give something like "loader version xXXXXXX" , where the capital X , are numbers, and the small x, is either "R" or "r". If it is a small "r" , that means its unlocked, if its a capital "R" its locked.
If you want to unlock your bootloader in the Xperia Pro, just tell me , and im sure i'll help you out, with a detailed tutorial, without having any problems.
Hope i helped.

Great, if you need anything else, ill be happy to assist you.
Hello, I was posting here because I've been having a great deal of difficulty really getting anything done with it. What I'd like to do is either unlock the bootloader, or at least root it to my computer to flash on a new ROM.
In order to root it, I was told to put it in MSC mode, allow unknown sources, and enable USB debuggin, all of which I've done. However, when I go to root it using either SuperOneClick, Doom method, or flashtool, I continually get errors, either saying ADB server is out of date, killing..., or in the case of the doom method that it cannot write any files because they are read only. Somebody mentioned you an overwrite your r800at with an r800i rom to make this work, but the link in that thread lead to some virus (I assume it was taken down a while ago). I put it to a stock AT&T ftf, and still no luck.
My problem lies in the fact that some of the threads I'm looking at are YEARS old at this point, most of the links are dead, and some of the advice is contradictory. I figured then that I could just get somebody to unlock it for money, but all the threads point to alejandrissimo, who I believe is now inactive.
All I would like is to root my phone and put on a new rom, preferably of ICS, with minimal difficulty. I've sunk something like 10 hours into it at this point, and now am the proud owner of a phone with the exact same firmware I started with. I've wiped my contacts like 8 times, and to be honest I'm just getting frustrated with the whole thing. I hate the idea of having bloatware all over my phone though.
So if anybody knows a good way either to root the r800at (and if possible could provide active links to the software), or somebody I could pay to unlock it and skip all this work, I'd really appreciate it.
Thanks for reading, have a good one.
I can't help you with unlocking bootloader (i have r800i with unlocked bootloader), but maybe i can help you with root
You didn't say what firmware are you using, but in general use Doomlord's zergrush method v4 for firmware .42 and below or Eroot on newer firmware (it's on chinese but it have one big button with word "ROOT" on it :silly: )
That is only for rooting and with that you can debloat stock firmware or use ROMs for locked bootloader.
SWM_installer V5 , should work on locked bootloader (once you get root) so you can flash custom GB roms.
To be able to install ICS/JB/CM/MIUI ROMS you must unlock your bootloader because they all don't work on stock GB kernel, and you need unlocked bootloader to be able to flash custom kernels
Here is some links, but i hope R800a users can help you more with unlocking bootloader

First, thank you for the very informative response. Here's some additional info, I am not sure if it will be helpful to you
My current Android version is the stock AT&T 2.3.3 and my build number is 3.0.1.b.0.285. I'm honestly not sure which of these things is helpful, but I'll try that Chinese rooting method. Got a long work shift tonight, but I'll report back later.
Thank you so much, I really do appreciate it!
