Guys I'm fairly new to all the flashing and stuff but have come a long way with my several xperiments :victory:. I've a Xperia Neo L and with the stock ROM (locked BL) I had made a Nandroid backup. Today I unlocked my Bootloader and installed MIUI 2.11.30 from MIUI Australia.
1) I'm just curious will my previous backup can be used to restore my old stock ROM considering the BL status is changed now?
2) Stock ROM is backed up with CWM Recovery ver 5.5 and I'm currently running CWM Recovery ver 6.0.1.2. Will this have any impact?
Please forgive me for the noobish questions...
BL unlock status shouldn't make a difference. Different CWM version can give problems afaik, but chances are it works fine because of backward compatibility in restoring.

Thanx mate! Will try restoring.
more important part is to use ICS kernel with ICS ROM, and GB kernel with GB ROM, same goes for backup's.

Hmmm Now I'm running a MIUI ROM based on 4.04 and I'm curious to try Turbo UI r4 based on JB 4.1. For that i need to first flash a JB kernel. Will my nandroid backups still be working as I'm changing kernels?
One more time..
GB kernel GB ROM
ICS kernel ICS ROM
JB kernel JB ROM
Any other combination MAY work, but they are looking for trouble.
Right Thankyou!

I'm currently on GB, do I need to install an ICS rom before I install a ported JB rom? Or can I go straight from GB (with doing a full wipe before hand of course)?

i have not asked him to flash bootloader
i said
ics bootloader is reqd for aokp roms 4.0.4 and jb 4.1.1
there are users who flash jb directly from gb roms and gb roms have gb bootloader so they went into semi brick and had to flash back to stock rom

Again, WTF are you talking about. That's not true you never need to flash bootloaders for ANY reason.

You are probably confusing the OP. DO NOT listen to this guy.
Thanks a lot for the answers guys. Just out of curiosity, why is neerajganga saying an ics boot loader is needed? That doesn't make sense to me because I've gone from GB to ICS without ever having to touch the boot loader.

I think you are confusing bootloaders for kernels. But by calling it a bootloader you will confuse the OP into possibly screwing up their phone. I don't know if you need an ics kernel for jb. I'm just trying to clear up the misnomer.

Being what I just went through with my phone... I assured I was flashing an ICS ROM with a proper kernel. Then move up into JB. I had flashed a wrong kernel and wound up having to back track and redo allot.
May seem like more work yet taking it step by step sometimes in the end is easier. Just a word of thought from a noob who twice thought he bricked his phone. Yet now works great on CM9 thinking of moving up into CM10 soon.
The new versions of siyah and dream kernel are both ics and jb friendly may be more but these are what I use

neerajganga, I think you're in the wrong forum. This is for the ATT SGSII model I777, your sig indicates you've got an I9100 (though that confuses me because even I9100 users never need to flash bootloaders except in softbrick recoveries, just like I777).
Hello all,
I am a super newbee in this field ( please dont laugh ) ! I apologise if i have failed to see the solution for my queries in other threads
I own a Samsung Galaxy S2 I9100 with the following config:
Android version : 4.0.3
Baseband Version : I9100DDLPA
Kernel Version : 3.0.15-I9100XWLP7-CL340913 [email protected]#3
Build number : IML74K.XWLP7
I have already rooted the device with the help of posts on xda. I aspire to put a custom ROM of Jelly Bean in my phone. I have certain questions abt it.
1. Can someone suggest me an apt choice of ROM to suit my current build?
2. will i be able to come back to my stock firmware incase of any problem with the custom ROM. If yes, how ?
3. can i partition my ROM and have to Androids running ? Custom ICS and JellyBean ?
Please help. Thanks in advance.
JB ROMs are still in development stages and need some time to get fully baked.
If you want to try one CM is great.
And you can return back to ICS anytime.
To dual boot JB and ICS you need to flash Siyah kernel.
I would suggest you to flash (install) CM9 for few days. Bcoz its better to be using known stable build for regular use. You will get an idea of what to expect of AOSP ROMS and what are their limitations.
Then you can plunge into exciting world of flashing nightlies (less stable) builds.
You can always go back to default samsung roms if CyanogenMod roms dont suite you. There are lot of custom Samsung rom based roms to choose from with very good customizations.
But before you do any flashing of rom, BACKUP YOUR CURRENT ROM.

Better flash Siyah first...

After Flashing Download the Custom Rom.Zip File You Want to Flash..
Boot into ClockworkMod Recovery (Siyah kernel's) Recovery...
Flash the Zip from Here

Yes, of course.
Ok so now that I've played with JB, I wanted to try out xperia ultimate hd for instance.
Problem is, I already had a lot upgrading from stock ICS to JB FXP.
So now the question: What are the steps to be sure there 's no problem at all while I change from
Flykernel+FXP
to
Xperia ultimate hd.
I unzipped the source, but can't find any ICS kernel to flash with flashtool. And I think I can not just reboot in recovery and flash the new rom, am I wrong ?
Searched for a clue on xda, sorry if I missed a post with the answer in it.
You should flash an ics kernel like rage kernel and flash the xperia ultimate HD rom in recovery. Don't forget about the wipes, it should work
What are the issues you are afraid of?

flykernel for ics has recovery just use it. You will want to flash the kernel first and then use the CWM from flykernel ics to flash the rom. Since there was no kernel inside the ROM this probably means it uses the stock kernel.
Ok thanks ! reasons why I want to change is :
-> Google Search is leeching my battery, I tried everything from disabling location or history, still draining do not know why...
-> No OTA on FXP, you guys know if there is any chances there would be on CM10 unoff ? CM10 supposed to bring OTA, do not know if FXP will.
->Still my battery is fine with smartassV2 / Sio, but I miss the auto brightness and I wanted a more stable / Battery friendly rom. Is ultimate HD the right choice ?
3 questions in one thread...:silly:
Hell everyone,
I have a couple of questions regarding the installation of custom roms.
Does anyone know why there is a requirement to first flash stock firmware before flashing a custom rom in sola?
kernel, rom, recovery, all come with the custom rom, so why is that? (my main device is a nexus so this requirement is very odd for me)
On a second note, if you do a nandroid backup say of cm9 FXP205, and go to whatever other rom, do you need to flash stock again before restoring the nandroid, or you just hit recovery and restore?
thanx and forgive my ignorance on this matter

For the first question
We always ask to flash stock ftf for two reasons
Firstly to get modules and certain dependencies from the stock rom ( thats why in cwm first rom is flashed and then system is wiped and not vice versa)
If u dun do that u will get installation aborted in cwm
Second question m nt sure coz I never restored trans rom nandroid
Bt bt bt.... Since we usually have nandroid backups of upto 1gb, I DUN THINK flashing stock would be a requirement
If m wrong plz correct me
Nandroid backup
For your second question, i have used nandroid backup in x10 mini pro to restore custom rom and saw no issues.
But in my xperia P sometimes I noticed that nandroid restore does not restore the custom bootscreen!!! But if you used advanced restore and restored every partition one by one issue seems to have fixed. So am not quite sure about the nandroid restore.
Thanks for the replies. However, any required modules/dependencies could be passed along with the custom rom, as it happens in other phones? What makes Sony phones unique in this aspect?

You are correct that the modules and others can be passed on through but that will increase the size of rom.So stock based roms can use the files already left behind by the stock ftf and hence there would be no need to include these module/dependencies files in the flashable zip.
Also stock based roms do not need to have kernel file as the stock firmware's kernel is already present on the phone,again reducing size.
The presence of locked bootloader makes sony phones special(although there are htc and motorola also).
In brief when u are going to install a rom that uses custom kernel,you need to have bootloader unlocked,so that custom kernel(not signed by sony)
can be installed e.g CM9.On the other hand if you have locked bootloader,you can't use custom kernel based roms and use stock based roms only e.g pulak's ultimate sola rom.
Hope this helps.
Hi all,
I've made all the necessary steps before flashing a new ICS Rom: Unlocked Bootloader, Recovery (CWM), Root, S-OFF, made a backup.
I've tried few ICS roms (MUIU and Cyanogen) and the flashing was ok, but once the new rom boots and I touch a screen, the phone reboots. It happens all the time, regardless of the rom.
The strange thing is, that it happens only with ICS roms, but when I install JB (2.3.4) custom rom everything goes smoothly anf the phone works just fine.
How can I prevent my phone to restart all the time? I want to upgrade my Amaze to the ICS.
Thanks.

2.3.4 isn't JB (Jelly Bean) thats GB (Ginger Bread). Sounds like you have bad downloads. Check your Roms MD5 Sums.

For you to run ics roms you first need to update to ics from a ruu. Ics has different firmware and changes the partitions also. Once you do that then you can install ics based roms.
