[Vibrant Q&A, Help & Troubleshooting] noah1017:
Those are both great 2.2 roms and they got me through many months of vibrant useage, I have nothing but respect for the devs but they are a little bit outdated simply due to the fact that the teams are working on other projects currently.

Like I said they are good but here is my breakdown (my preferences are to have to to as little as possible on the spot fixes, in a perfect world no fixes would be cool but it would take so so so much work and the Devs that make these roms are

already awesome enough to do this in their spare time for us vibrant users

. But I do prefer when fixes or tweaks are in the op that are known to be compatible)

NONE OF THIS IS OUT OF ANY DISRESPECT TO ANY DEV, I JUST WANT TO HELP PEOPLE FIND A GOOD ROM FOR THEM.

For 2.2 :

I would say Toxic Crazy 8, They are very fast but as with many 2.2 roms it has a bug where there's no voice mail notification icon. This may be no big deal to you as there are many workarounds including the use of aps like visual voicemail.

Zendroid does not have the voicemail issue but does freeze up and get laggy during heavy use (for me at least).

2.2.1. :

For 2.2.1 Bi-Winning is a solid rom. It hasnt been updated for a while so it may not have all the tweaks of newer roms but it is fast and stable. I personally missed having any skin or smiley's in my sms. This is something that can be altered by a user but I am reviewing based on an out of the flash experience.

Jrafaels Port of Ultimate is awesome! The only thing I had to do was download launcher pro and I was set and stable. Very Fast! super quick on aplication loading!

Froyo Kernels :

For speed and battery life combined, my favorite was immortality 2.2.

The dev has switched to GB now so no more updates but its great and stable as is.

For all out battery and a small sacrifice in multitasking speed Bali, I forget which specific version but its the one that will come with Toxic Crazy 8.

Gingerbread:

I have never flashed a Samsung made rom (JVS, JVR, the upcoming JVT etc..) This is partly due to complication of installation for me as well as being scared off by reading about some difficult bugs in the forum. If I was not planning on buying Tmobiles sgs2 asap I would be playing with them. I really liked explodingboys froyo roms (simply galaxy) as well as EDT's members roms but as I stated I'm apprehensions to attempt a flash. (once i bricked because I missed some op instructions on simply honey)

CM7.1 and Nightlies :

These are less intimidating to try than they seem when first reading the op. Cyanogenmod is really cool and impressive, instead of rebuilding a samsung (or any brands) rom they made their own. Its really high caliber work and I will not be at all surprised if I see Cyanogen mod powering one or more future STOCK Samsung devices.

However, with nightlies you cant dial 911 for an emergency. this is an experimental build so DONT GET MAD AT THE DEV, but it still freaks me out enough to not use it as a daily driver.

my Number 1 ROM is ::::::::: MIUI stock version

I must add that every current version of MIUI is pretty stable and amazing. The reason I want to be stock MIUI for now is because the PowerMod System Enhancer (currently MIUI exclusive) will litterally make your phone about twice as fast and better battery of around 10 to 14 hours depending on usage, some may get more.

I have tried MIUI 3 times and the first two were in june and august of this year. Since then it has become stable enough for use as a daily driver. Play with the themes app for a bit and understand what customization really is :)

Tweaked kernel V2 is great for speed as well as battery on MIUI.

GPS : It is important to know that many (myself included, ive had it in three vibrants) have a hardware defect that makes GPS not work. From what I can remember from some old forum that i couldnt find today, the GPS chip is touching something else on the inside and it screws it up. There are hardware fixes but much like adding a FFC I am WAYYYY to scared to try that stuff hahah :)

****

BIGGEST THING : READ EVERY OP CAREFULLY, THEY ARE NOT ALWAYS THE SAME INSTRUCTIONS AND I WOULD RECOMMEND TAKING NOTES WHILE READING BECAUSE YOU DONT WANT TO BE LOOKING AT A RECOVERY SCREEN TRYING TO DECIDE WHAT TO DO NEXT

I may post this in another section if I see people with similar questions so please dont get mad at me xda :) as I said I just want to help, you can let me know if I did with the Thanks Button.
