hi guys
doing this for a few friends at work, so i want to get it right tha'ts all
we get LT18As and i'd like to root it.
i've read about this:
http://forum.xda-developers.com/showthread.php?t=1683189
would this work for LT18A?
i can't tell since i thought that you can only flash kernel in tft format if you have unlocked the bootloader..
anyway sorry to be a pain
thanks
arc and arc s are almost same . so the method in whe post will work for you also get the firmware for arc s from the general section and follow the rest steps in the thread you have give .
1) get a stock .562 firmware for arc s ftf flash it to your mobile and use this thread
http://forum.xda-developers.com/showthread.php?t=1601038 ( thanks to doomlord )
2) install x'parts from market and install CWM
3) get any custom rom from dev section which can flashed on locked bootloaders also and flash them from cwm.
all you need is to take a bit more PAIN to find them :laugh:
unlocking bootloader breaks sony warranty , i hope you know this. also unlocking bootloader is neded only if you intend to flash kernel and not custom rom.
also mostly firmwares are in tft or zip format and kernels in img or sin types
Follow these steps for a rooted ICS arc s
1. flash a rootable ftf like this one
2. download and extract the files from this
3. put your phone on debugging mode and plug into your pc and run the Runme.bat file from the extracted file
4. phone will be rooted
PS - works for locked bootloader :highfive:
Thanks for the advice guys,
I actually managed to down grade to gingerbread and then I tried flashing jelly sandwich from the recovery. But I got into a boot loop.
Is it the way I did it? Or is it jelly sandwich?
What rom do you guys use?

If you are thinking of flashing jelly sandwhich, here are the steps (which the original post doesn't actually say). Also flash ics first just for safety measures.
make sure in cwm before installation
1. Wipe data/factory reset
2. wipe cache partition
3. go to mounts and storage menu and\
4. format /system
5. format/data
6. format cache
7. exit mounts and storage menu
6. go to advance
7. wipe dalvik cache
8. wipe battery stats
9. exit advance
10. install Jelly sandwich from sd card without rebooting

last version of ICS is not rootable without unlocked bootloader so you need to downgrade it then root and you should use the recommend kernel also, custom kernel might caused that.
Using Ultimate HD v1 /2 or Jelly Sandwich both good

well you need...

Toggle Asserts ICS (Whatever ROM made for ARC/ARC S)
I also want to know!!!!!! I have been trying to install CM7 on my Arc Lt15i phone for a long time but was never able to due t the dreaded status 7 error. I toggled the script asserts but it still did not help me at all. Then I tried CM9 and it was the same damn disaster! Please let me know if you are able to install it. I hate the fact that I have the ARC S and the ARC Lt15i problem always colliding together. I hope this will not be a problem when JB comes around!

It's simple, flash the kernel, install the ROM, done.
The kernel is in the .zip file(boot.img). You have to extract it. Place the zip file on your arc. Flash the kernel with fastboot or flashtool. Then enter cwm. Wipe Cache, wipe dalvik cache and factory reset. Then install the rom.

Simple like that
just follow the instructions provided exactly 100% and you should be fine.
however,
last time i tried to install fxp cm9.0 by flashing the kernel 1st i almost killed my phone and it scared the **** outta me. i cant even enter recovery or fastboot and i had to reflash a stock ftf in flashmode to try it again. i think that flashing the zip file together with a full wipe then only the kernel works better..any ideas?
So, i want to try Jelly Sandwitch 5.0. It seems nice to me and everybody tells that this is a very fast ROM.
I have unlocked bootloader.
This is how i tryied to instal JS 5:
- root my phone with DoomLord method (downgrade kernel, root then replace the kernel with the .587 one).
- install cwm with x-parts
- reboot and enter the recovery menu
- wipe cache, data, dalvik
- install from zip
Jellybean have an installer that let me choose different option like the launcher, keyboard, some apps and some other options.
I've tryied 3 times using different option like install link2sd, wipe data, and so on, but everytime it ends up just showing me the sony logo, then i have to reinstall everything, root, cwm, etc.
I can't post in the Jelly Sandwich thread on the developer forum so i ask here if i'm doing something wrong.
Also, can you suggest me a rom good as JS5?
Thank you in advance (and sorry for my english)

Try flashing doom kernel ver.5 . Many users have the boot loop issue with stock kernel.
With doom kernel it works (for me too).
First flash doomkernel, than wipe cache, dalvik cache, data, and format /system
Reflash the rom and it will works.
The only kernel that works on my Arc with Jelly Sandwich 5 is XArc.
I tried other kernels but always get bootloops or crash just after typing my pin number.
XArc is great but don't provide HDMI.
JS 5 is probably the worst JS version. Maybe you should try an older version.

if you have an unlocked bootloader and installed a custom kernel, I don't think you need x-parts to install CMW as the kernel contains it?

I have an unlocked bootloader but not a custom kernel with cwm in it. Do you have a link for a guide about installing cwm without x-parts?
I tried it also and i got bootloop. Then i repaired phone and gave up...
After unlocking bootloader, find a custom kernel for your version of android ie: Ginger bread/ICS, DoomLord is a popular choice.
Keep in mind there is a version that can't be rooted, from memory its .62, in this case you have to down grade to .42
Flash the kernel:
fastboot flash boot boot.img
You will have root and custom recovery installed.

hello, I have an Arc S LT18i with official 4.1.B.0.587 rom and locked bootloader.
I would like to switch to a custom ROM (e.g. Jelly Sandwich), that is supposed to be pre-rooted and doesn't require an unlocked bootloader.
Which is the fastest way to do the switch? Do I have to root my current rom first or this is not necessary?
It is my undestanding that to install a custom rom I need to install a recovery (CWM) first. If this is true, are there ftf files that include a recovery?
thank you very much
Slow, but fast
FTF files with included cwm aren't existing, forget it
To get CWM on your stock rom in order to install jellysandwich you have to get root access
To get root access you have to flash .562 kernel, you need flashtool for this, and then root with doomlords ics rooting toolkit
After you have CWM installed via x-parts, an app you can find in play store, you can put jellysandwich on your sdcard and install it from there
I recommend for a locked bootlocker this way in CWM:
wipe data/factory reset
wipe cache partition
format cache + data + system (in mounts and storage)
wipe dalvik cache
then install rom
If you've got problems, write it in the thread
wow, that was a quick answer!
I'll try to do that and tell you how it goes. Just for information, would it be easier if I unlock the bootloader first? I'm going to unlock it eventually anyway.
I've no xperience with unlocking bootloader, so i can't tell you advantages of a bl unlocked rooting process, excuse me...
I really appreciate your help, but unfortunately I couldn't manage to make any rom work, I tried jelly sandwich and ultimate hd and always got stuck in a bootloop.
The biggest problem is that every time I had to reinstall full .587 fw, then .562 kernel, then re-root, then restore .587 kernel, then re-install x-parts... it took hours just to get back to "normal".
I surrended and unlocked the bootloader. This opened a whole new world.
In a fraction of the time I was able to install a kernel with cwm, and succesfully test several custom rom afterwards... not only they worked, but I could flash a new one in minutes, without worrying about root etc.
Just to share my experience...
there's a specific thread in sony official forums about this and its really easy
Hello everyone ,
I have rooted my phone and install recovery many times on it, for put a new custom rom. But when I flash a rom my phone reboot and just stuck at sony logo. I can put only the original ftf with flashtool for boot .
My bootloader is locked but many roms says "for locked bootloader", but on my phone they doesn't works.
I'm lost.

4. format /system
5. format/data
6. format cache
7. exit mounts and storage menu
6. go to advance
7. wipe dalvik cache
8. wipe battery stats
9. exit advance
10. install custom rom from sd card without rebooting
It's sad to say that... but it's what i've do :/.
Hum thank you i will retry :/ may be can you tell me a perfect rom ? I love jelly bean i had it on my old HD2.

Nooooooo o: I do that since 2 weeks and nothing works but with you yes
Thank you very much you are the best my phone boot :laugh::silly:
adjust the rom and kernel
Hi,
Hopefully someone can help. First off, when I try to unlock bootloader, It says it's unlocked. I can root my phone through flashtools with no problems also. I tried the ICS and JB roms with a lupus kernel as described on Youtube. I follows the instructions to a T and when I install the rom from the sd card, it never installs,...well it does install as in it goes through the installation procedure. It just reboots to the recovery mode after the installion instead of the rom etc to ( the lupus or doomlord recov mode depending on the rom). I have tried different roms and downgraded to ginger 2.3.2 ( I am currently on 2.3.4) but there is no change. Any help would be great thanks ...

Hi,
I bought the phone second hand. When I tried to unlock bootloader, it says its unlocked already...must have been done by previous owner
Did you follow all the instructions for instlling a ROM???
1. Factory reset
2. Format-wipe /cache (it says formattting /cache when doing factory reset, but do it anyway)
3. Format /system (its on mounts and storage menu)
4. Wipe dalvik cache (its on advanced menu)
5. Fix battery/wipe battery stats. This depends on the recovery, but is the same thing...
6. Fix permissions. I think this is what you are doing wrong of missed out.
Btw, if you can enter fastboot mode and flash custom kernels, you have unolocked bootloader

How are you flashing your kernels... via Flashtool in fastboot mode, or using the windows (if you're using windows) CMD and the fastboot command on Android SDK??? 'Cause maybe something's wrong with the kernel or the rom Zip you're using...
Which Roms are doing this???

have you checked what kernel you have flashed? lupus kernel has 3 different versions one solely made for gingerbread and for ICS which is now very updated to work on any stock based ICS rom he also has a CM10 based rom which will work on any CM based roms as well as. have checked the roms recommended kernel to use?
