[Q] Can I get back to 2.2.? from 2.3.3?

So, I am thinking about putting custom ROM to my SGS i9000. Its currently with Android version 2.3.3.
I've been reading through this forum and most of custom ROMs are for Froyo? I mean many of instructions say that you have to be on Froyo if you want to use this ROM.
My question is must I get back to Froyo somehow or is it possible to put custom ROM for my current Android version?
Sorry about my noobishm. And I hope my english is good enough for you to understand.
Many thanks

Wrong, most of the custom roms are based on gingerbread. Stay as you are mate more excitement to come

You can always switch between 2.2. and 2.3.x. The only thing you need to pay attention to is that you need to flash the proper bootloader.
Flashing a bootloader is risky insofar as if the bootloader is not flashed properly, your device is thoroughly bricked and can only be revived by Samsung (or someone with the proper hardware). Furthermore with Froyo you may erroneously flash a locked bootloader which would make you stuck with that one ROM for the rest of your device's life, so make sure you only flash unlocked ones.
This said, there are actually few ROMs out there that still rely on Froyo (Insanity comes to my mind as an example). So you probably won't need flash Froyo just because of custom ROMs. Simply follow DonVito2020's link and choose a Gingerbread one.

Look at the fifth comment. Nice instruction, but is it safe one?
I'm gonna try it if it is.

It looks like a good how-to. Whether it is safe or not I cannot tell without looking into the files, however since the post links to Gingerbread ROMS, not Froyo ROMs, it is most certainly safe, as far as the bootloader is concerned (at least I have never heard of locked Gingerbread bootloaders for the Galaxy S).
Though since you are already on stock Gingerbread, take a look under at the Baseband Version under Settings - About Phone. The last three letters will tell you which release of Gingerbread you have. In my case the baseband is I9000XXJVR, so I have JVR.
If you already have JVQ or JVP, you can flash the kernel and then Darky's Rom directly. Just don't forget to backup everything.

Couple of questions...

New to android world and looking for first rom. On stock Froyo 2.2, rooted, clockwork installed. Which rom can be installed without Odin? Do kernels have to be installed separate, if so, is it before or after rom install? Looking for sense-like ui.
Thanks!!

If you want sense go buy a HTC lol. Odin is going to be your bread and butter since its the easiest way to flash to stock and flash kernels. Most roms can be installed without odin though. Go to the dev page and look around at the roms and make your choice. Remember Gingerbread needs new bootloaders (except Cyanogenmod and Miui) and as always read read read.

[Q] newbie questions about custom roms (bionic)

For droid bionic: custom rom such as Eclipse and Liberty, are they based on the stock moto rom or based on CM7?

wow this is a premature and unneccary thread go to adroid development stickied rom/scripts/hacks etc.. it has a line up if they are 902 based 901 896 etc... click on the link it will probably bring you to rootz wiki and the rom will tell you if it is stock etc.. kinex is stock based eclipse has customized but has parts of blur still in it but is mainly aosp.
search button is your friend

Sorry, if you feel this as unnecessary thread. I did mention the question as newbie question. I did look/search & couldn't find the answer I was looking for. The reason I asked is that whichever custom rom I look, it REQUIRES some specific version from moto original rom such as 902, 901, 893 version to be compatible with that particular rom. That's why I though those custom rom are based on moto rom. I just want to understand why can't we just flash to custom rom like CM7 on bionic. If you can give me a clear answer it will be great.
Thanks in advance.

The reason that you can't flash CM7 over top of stock is this:
Think of CM7 as an "update", since we are on a locked bootloader.
Now, we can't change the kernel, which is the core of the Android OS.
So, with CM7 we can't have everything that CM7 has to offer.
So devs port the CM7 code so it will work with our kernel.
This means that whatever kernel version the dev uses to write CM7 must be installed before you flash CM7. Otherwise you have a ROM with a kernel that is not compatible with it (and that is not good). It would be the same as flashing a ROM meant for an HTC phone to a Motorola phone like ours. It just wouldn't work.

Thanks, Priddyma, for explaining .....
So, basically, custom roms for bionic such as Eclipse & Liberty are built based on particular moto locked kernel, right? Is it also the case with new bionic roms with ICS features, are they built around the .902 kernel with ICS features?
Another question, when we do OTA official updates, for instant update from .893 to .902, the official updates (from Motorola) are capable of flashing to different kernel? In other words, is it possible to flash kernel (If you are Motorola dev & have the unlock code)?
What I want to know is that in the future, if Motorola is nice enough & could release the unlock code so that we can flash bootloader/kernel to whatever we want.

It's already been stated by verizon that it's them locking the bootloader, and not moto.

[Q] STOCK VS custom ROM for D3 XT862

HELLO ...i am new to the Android world but an expert in the windows world...... i do also love linux
i have a Droid 3 XT862 running Android 2.3 and i want to experience the freedom of rooting my D3
i had hoped my first Android phone would be high spec running the latest OS (or almost) but i am not ready to risk using a touch-screen only phone because i hav had some bad experiences with touchscreen keyboards....thats pretty much why i got the D3 instead of the RAZR or the DROID BIONIC
QUES #1:
how difficult is it to revert back to my original Android 2.3 OS if i find it difficult to use a custom ROMS?? i really want to use my camera so a chance to revert bak to my original V2.3 wud be nice
QUES #2:
is the phones ability to install apps affected in any way by upgrading the Android version ( FOTA) or rooting?? for example..... i am going to test run my V2.3 os for a while and install many apps, will these same apps be able to install on the custom ROMS?? ...... wat are some of the advantages or disadvantages for installing apps on stock V2.3 and then try to install the same apps on any of the below custom roms:
OFFICIAL CyanogenMod 10.1 (Android 4.2.2): [NIGHTLIES]
[ROM][JB] [4.2.2] Avatar ROM for Motorola Droid 3 (solana)
[ROM][4.2.2][OFFICIAL] LiquidSmooth v2.1 - solana -
[ROM] Official PACman Droid 3
[ICS AOSP ROM] "AOKP" (Android Open KANG Project)
[ROM STEEL DROID]
[Closed]RemICS-UX v1.3.1 - Galaxy S3 on Your Droid 3
.....ETC
QUES#3 :
BBM Messenger will be available for phones running Android 4.0 or higher this summer, I am interested in trying it out and i want to know if these custom ROMS will allow me to install it without much difficulty......
QUES#4:
I am assuming that once i root my phone and install a custom ROM using safe strap or a similar tool, this is the same as dual booting, in which i can switch between stock os and custom ROMS at will.......am i right ??
QUES #5:
How may Custom ROMS am i able to install while making sure my phone is stable ??
THANKS MUCH !!!!!.....

Reverting to stock is as simple as plugging the phone into your computer and flashing stock firmware with a utility. Custom roms and rooting shouldn't affect app installation, with the caveat of some video rental apps won't work on rooted devices(piracy prevention). BBM should install on any custom rom ics and up, but until it's released we won't know for sure. All that being said, sometimes a particular app may have issues with custom roms but it's the exception, not the rule. Yes you can switch roms similar to a dual boot, although data from one rom isn't visible to another, like app data, text messages, call log. Sdcard contents are though. Safestrap creates img files for custom rom slots, you can have up to 4(in addition to stock) I believe, although I no longer use safestrap so I'm not totally sure. The more you have the less Sdcard space available and the custom roms can be pretty buggy sometimes. Personally I just flash over the stock rom since its so easy to return to stock if needed. I also only run gb roms since I need the camera

Cant thank you enough bro.... just glad that i can run ICS apps on the custom roms and revert back to Stock when i need it ..... and i think it will be a good idea for me to install a GB ROM as well .......
you said "The more you have the less Sdcard space available"......... does that mean these custom roms are supposed to STAY on the SD-card ??
i thought after u installed the custom roms, you could do watever you want to the SD card

Flashing future official ROMs after unlock -

Hey guys! My apologies if this is a redundant question, but I just wanted to be sure:
If ASUS decides to actually put out an official KitKat update for this thing eventually, would I still be able to try it out / install it normally *after* I've unlocked?
If so, what exactly would be my procedure? Will I be blocked from getting or installing the OTA, or would the process be no different?
There's been some great progress it seems on custom ROMs for this thing. I'm a bit gun shy admittedly, as running custom ROMs on previous devices led to a lot of instability. I guess I want to ensure I'll still have the option to try out a future official build if I choose. Thanks in advance!

Yes you will definitely be able to update to KitKat once released. However you won't be able to get the OTA update automatically sent to ur tab once u unlock it. But its pretty simple to get it. After Asus has pushed the ota to devices, the also upload the firmware to their website. U would simple download that and place it in the root of ur internal SD, and reboot. Tab will recognize the update, and give u notification for installing it. And u continue with that. Very simple.
And as for the Roms , the cromix ROM is by far very stable ROM. I have tried it for very long time, and has no issues at all, and the plus side is u can do a lot of customizations yet the ROM still runs faster than stock. I strongly recommend cromix ROM.

This is not 100% true. The current official ROM will only flash with the stock recovery installed and not a custom one, so I would assume the same for any update.
It's not an issue to flash the stock recovery back but it will be an extra step.
Also if and when an official KitKat comes out you will more than likely have to wait until a new recovery is made that is compatible for a custom ROM after that.

I never understand why people are pining for the stock rom - no matter which version or update....
I would feel helpless and lost with only the stock recovery! Lately I've been trying to help several people on stock firmware with corrupted data, no custom recovery, no root, locked bootloader.... You're toast!
All you can do is send it in to Asus and pay a bundle! Whereas unlocked you just fire up fastboot or custom recovery and start to fix it!
Besides - once Asus releases a KK version for this tablet you can bet your.... house that sbdags will have a custom version of it out in no time. And it's going to be better than Asus firmware, receive frequent updates, can be flashed with a custom recovery....
A no-brainer IMHO
