Help with xperia arc s LT18i downgrade to android 2.3.7 - Android Q&A, Help & Troubleshooting

Hi to everybody, well i bought an xperia arc s 2 weeks ago, and i update it to android 4.0.4, but i dont like it, its to slow and has a lot of lag, ive been asking in yahoo that someone give me the generic rom to downgrade it, this is my last hope, please, could anyone give me the generic rom to downgrade my xperia arc s, please,
The number of the model is: LT18i
Android version: 4.0.4
baseband version: 8x55A-AAABQOAZM-203028G-77
kernel version: 2.6.32.9-perf
[email protected]#1
build number:4.1.B.0.587
Please help me, give me all the stuff that ill need to downgrade my phone please

Hello, my name is Andrew.
I recently got an xperia lt18i phone.
For free.
this is my first touchscreen smart phone thingy.
I would like to install a nice ROM on it, as currently it has problems connecting to WiFi.
Known issue i was told.
Currently it says:
Android version:
4.0.4
kernel is:
2.6..32.9-perf
[email protected]#1
Build number
4.1.b.0.587
My main problem is that i can not find FTF files that i could flash to it, to enable root hacking and unlocking and so on.
Mostly every link is dead i find.
Could someone help me where could i obtain a root-hackable FTF file i could flash ?
I can use the flashtool app, no problem there.
I managed to allmost brick this device as i found only 1 FTF file i was able to download,
sxperia_arc_s_lt18_4.1.a.0.562_nordic.FTF
afterwards the thing was unable to start.
So i searched and after a few attempts i managed to find
LT18i_4-1-b-0-587_Generic Global World.FTF
file, i managed to flash it, the device works, but WiFi problem remains.
What i would need is a working link for an older FTF file that can be root hacked by flashtool. Then i will need to unlock the bootloader, i found the tutorial for that.
The other thing i would need to obtain is a custom FTF file that has WiFi fixed.
I can find download links for files like that, but they are dead links.
So please, if anyone has proper and working links for downloading:
root hackable FTF file
worthy custom FTF file
I would be thankfull.
Thank You for reading.

the last miniCM7 requires a custom kernel& unlocked bootloader.
you can't use it with stock SE kernel, sorry
repaire with SEUS or if your phone has an unlocked bootloader, flash nAa's kernel
first i am sorry for the position of the thread, i didn't post, i asked a friend to do it
second i really appreciate your help friends and thank you alot
from your help i understand that i must first unlock the bootloader, then flash the kernel and finally install cyanogenmod 7, am i right??

the (best) way :
unlock your bootloader
install miniCM7 2.0.7 (to maximise the compatibility/minimise problems ) it works with stock kernel and a little with custom...
flash the nAa_kernel04
Install miniCM7 2.1.2
read my FAQ, and the dedicated thread about miniCM7 and the kernel before trying anything
you will find 2.0.7 here

if you are installing older version of MiniCM then try going to recovery mode and wipe battery stats then reinstall it will work hopefully
and then you can crack bootloader and install Custom kernel as matmutant said

[Q] GT-I9100P (orange UK) firmware/rom/kernel ?

Hi all,
I have the following device:
Baseband version I9100PBVKI2
Kernel Version 2.6.35.7-I9100PBVKI3-CL608158 [email protected] #2
Build number GINGERBREAD.BVKI3
It looks like there aren't that many discussions on the P variant, and i haven't been able to track down the official stock rom/kernel for this model, can anyone point me in the right direction please? I have checked the official rom page but there isn't anything for PBVKI2
I have used Odin to put on clockworkmod 4.0.1.5 as i was doing some experimenting, i'd like to put the device back to the way it was if possible.
Many thanks!
Try CHECK FUS post .
jje
Sorry, forgive me, i dont understand, what does that mean?
Thanks
Search XDA for the post entitled CHECK FUS and read it .
Or check Samfirmware.com
If you want to find firmware that is not in the stock or provider roms posts .

Hi jje, i follow now, sorry about that!
I've checked Fus (windows) and fus (market) both are identifying my device but aren't able to find the I9100P UK Orange firmware to download, only I9100P France . I've mailed the developer but i'm guessing its not there as noone has it yet? Or something? i'm a bit lost
sammobile oinly has the french one too
Update:
Developer has kindly added the UK Orange I9100P firmware to Check Fus

Hey Spoonflames,
have you been able to find the original kernel for this? I've get the FW but the kernel would be nice to have...

Thanks! I didn't know you could "dump out" your own kernel, is that difficult to do?
So your original kernel that you have extracted and now shared, is that in french or specific in someway or something or are these kernels generic for all GT-I9100P?
I'm about to root mine and as such I need to put a insecure kernel in first but then I would like to put a stock kernel in again, can I use your or should I try and extract my own. My GT-I9100P is on Orange but here in UK.
Thanks for your help!
You can use that one you have now..
also u can use HC-KTOOL from market to dump ur own kernel

Hi,
You're welcome
i've use HC-KTOOL (as Nyssa1104 say), but it doesn't work on ours GT-I9100P.
You need to edit your ro.product.model=GT-I9100P to ro.product.model=GT-I9100 , so without "P", reboot, and now HC-KTOOL work
Also, you can use my dump to flash yours , as you have the same original kernel.
Hey guys,
I have the Orange UK 9100P also. Can you list the steps you've taken/will take to root it? What custom ROM are you planning on putting on it or are you just after ROOT on stock atm? I've spent the past 18 month playing with HTC's and this just seems foreign to me atm...
Model Number: GT-I9100P
Android version: 2.3.4
Baseband Version: I9100PBVKI2
Kernel Version: [email protected] #2
Build number: GINGERBREAD.BVKI3
Thanks and sorry to be such a pain!

I'm being such a paranoid moron today - sorry guys
Just starting to get my head around the 101 different kernels. The Desire was sooo much simpler to root and S-Off
So in short - if I download the 9100PBVKI3_insecure kernel and follow Odin's rooting guide I will get my stock ROM, rooted, with busy box/SU and a yellow triangle on start-up... correct?
I can then take the Kernel listed above and replace the insecure one and the triangle goes away but the root persists?
Can I then use ClockworkMod to install ROM via recovery as I did on my Desire?
So many stupid questions I apologise... I will give the knowledge back to the community I swear
Also, which ROm on FUS is the UK one... there are several French ones and several that say (Made by user)... I presume the made by user would be the one requested earlier in this thread? I could then use this stock ROM to return the unit to "normal" for say warranty returns etc?

Looking for exactly the same information , and also coming from a Desire , which was simples ! and sharing a small amout of paranoia ! lol
Hi guys. I am new on forum and I own a new GT-I9100P Orange France. I have it for a couple of days and I think of a root method. This is my first Smartphone, so I am a beginner. I found this thread from google, I managed to learn something about rooting, but I still have problems. Let me explain what I understood and correct me if iI mistake.
So, GT-I9100P's kernel can't be rooted. I found on a thread here a page that talks about kernels and I managed to find an insecure kernel and a quick root .cmd file, thanks to Nyssa1104. If I falsh with Odin that kernel and then I run the rooting proccess, it should end successfully. But, besides the stability problems, a red triangle appears on boot. So, I understood that, after I root the device on a insecure kernel, than I must change back to the original (you named this "stock" I think) and it will be alright.
I have some questions too: can I find exactly the stock kernel??? If I change it, will the phone remain rooted??? Before I launch the root.cmd, the phone must be in downloading mode??? And this change will affect it's performance and stability???
Thanks a lot for attention and sorry for my bag english!
Please help me! Anyone here..?

Yes to root turn fone off once off press volume down(-) home & power buttons all together. look for your stock kernal and reflash and you be ok and yes root will remain.
original http://www.filesonic.com/file/4305715615/GT-I9100P_BVKI2_original.zip just make sure double check ok main link here http://forum.xda-developers.com/showthread.php?t=1101671
So, to run the automatic root procedure (root.cmd), the phone must be turned off and in download mode, thanks for answer. After it finishes, it will restart, won't it....
And after root I need to return to the original kernel. Just 2 questions:
1) How long does it takes to reflash wih Odin and I must wait some time before reflashing it?
2) This change will generate stability problems? What are the risks?
Hi again guys! I read about the CF-Root Kernel, which comes with root preinstalled. I think that I will flash this kernel because it's easy for me, a beginner, to root the phone. But on another forum I heard that GT-I9100P can't accept much kernels because it will lose it's NFC capabilities. Can you recommend me a kernel which is safe for my phone? Please, help me!!!

Something else: my phone kernel is BVki3, not BVKI2. So this means that the phone will not work with this kernel?

Hi, a long time ago I installed CyanogenMod 6.1.3 v06 on my Xperia X10i
Android 2.2.1

Help X10i [Re flashing information required]

Hello,
Sorry for starting a new thread, but i didnt find the information i'm looking for in another thread.
Recently i've got a Sony Ericsson Xperia X10, well i don't kow anything about flashing this phone i've really use a Samsung, but i find it very usefull as a Camera and maybe if it works ok i could give it to a friend or family.
When booting i ve got the SE screen, then the following message:
"Goroh Customized SPL.
Booting Custom Kernel...
Bye!"
After this the XPERIA screen apears an after that one other saying "XPERIA Wolfbreak edition".
I think its rooted because it have super user but i havent tryed to change anything till i'm sure of what i'm doing.:fingers-crossed:
I really want to fix the phone the original owner (my father) told me he stopped using the phone because sometimes it rebbots by itself and some contacts get erased. (i believe this could be a problem of the rom or maybe the memory, not sure).
So i want to test changing the phone ROM and see if it solves the problem, the thing for me is that all the tutorials take for granted a phone without modifications, but this one already is. So i need to know the how to do it and change the ROM for a newer one.
In the specifications tab i have the following:
Model: X10i
Android Version: 2.3.6
Core: 2.6.29-modFXP-DoomKernel-V04b [email protected]))
Cmpilation: RRQ I LOVE BMG
Thanks for the replies,
Any Help is Welcome.
:highfive:
You could try updating through Sony's Update Service...http://www.sonymobile.com/global-en/tools/update-service/
