I'm running Gumbo 1.5c right now.
I've been wanting to upgrade to a 2.1 Rom for some time but I've sort of hesitated until the Sprint Release happens. This, of course, looks like its going to be another month before it comes to fruition. So, I figured I would go ahead and take the leap. I do have one question though;
Do any roms support full Flash yet? I would like to see flash work in my browser.
If our browser will not support flash can we port one over from a phone that does once we load 2.1? The NexusOne has flash, right?

Can I use SetCPU with the ROM? Or do I need to flash another kernel?

Best thing to do is just try it i'm running darchlegendv4-2 and it is fast and in my opinion probably just as good as the 2.1 update
Ah. Rather than make a new thread I'll continue to post in here first:
Can someone link me to the news/weather widget APK that the NexusOne has. I know someone ported it over for 1.5 and I really use it a lot.
Thanks!

Flash works, but streaming is problematic. It works for some sites/applications but for the most part even when it does work it's like watching a slide show. I'm afraid that the Hero just doesn't have enough horsepower to stream flash video via the browser.
i think the current clock speed probably doesnt have enough power but if we can OC it then we'll probably get somewhere

Full flash or just flash lite?
How would I go about adding full flash to my Rom?
Full flash is useless on this phone... Like waiting for a stripper that shows up 2 hours late and then is fat and ugly to boot.
I dont know why people want flash, You get a more robust browsing experience?
Well a slower one too i suppose.
i thought we werent supposed to use SetCPU for the newer ROMS cause it has a built in power manager

That is correct. You beat me to it. I also heard that SetCPU is not compatible with the latest jumbo kernel in these CDMA Hero 2.1 ROMs anyway.
So I assume that flash is something that must be cooked into a rom, not something that can be put in retro actively? Is this correct?

However long it takes you to get an Evo? If you can figure out how to overclock this phone Flash might have a snowball's chance of being usable on the Hero.
My problem with flash is that it is processor intensive and just sucks the battery out of the device. I just turn it off, no matter how feature complete it is. Also, If I have to overclock my device to get it even run "at-par", this will suck my batter down even more.

im looking for the fastest rom to put on my wing i been searching and looking at all the roms but i cant choose and i been reading that there is a windows 6.1 manila rom or something like that but i cant find the download for it anyone willing to help :]
Well the best ROMs I think are Just2Clean and Open Touch 6.5 lite no spb.
I use the Open Touch one cause it is real fast and comes with good programs that I use a lot of and I've been using it for a long time. Those Manilla ROMs suck and are slow even while being overclocked and the TF2D eats RAM especially if you also have S2U2 in the background.

That's based on one of my older ROMs. Just2Clean.
They modified it by adding a few bits of software. ^_^
I happened to run into that video yesterday and a post in a different forum describing it. It was lucky that I found it before you asked.
I'm also working on a more current ROM, JustStable.
I also made a JustMe after Just2Clean.
yes thats the one that i want which one do would you recommend for my wing cause im getting tired of not having enough memory to open the camera and i want to have a fast phone too that works with everything :]

Just try one. JustStable hasn't been released yet, but it's the newest. If you want the ultimate in RAM and storage space, try JustMe. I have NEVER run out of memory while using it. And you also get 70mb of FREE storage space.
I haven't finished JustStable, but there will also be a stripped version.
Any ROM you get from these forums will be 100x better than the tmobile one. The only thing required is that you read up on:
HardSPL for Herald/wing
How to flash through an SD card for Herald/wing
And what a ROM is.

No, it doesn't look like that. He themed it differently. The core itself is my ROM. The speed is my ROM.

I don't overclock my phone. No need to in my ROMs. JustMe is a little more complicated. It's not really meant for newer users. It allows you to create a custom ROM. If you just want a ROM, try JustStable, it's not finished, yet, but it's "release" quality right now.
Search for the "how to flash" guide.
JustMe requires that you CREATE a custom version of my ROM.

Blur/system only
Pulse/system only

Thanks man!
Just out of curiosity, when you have system images but not the boot images or recovery images... what can you do with the system images and what do they include i.e. apps, widgets, framework, etc? I'm thinking of learning on how to cook and develop roms. Unfortunately my degree is in networking, so I do have some learning to do.
THX!
good job,Drizzy!
waiting for your full blur ROM 4 G1!
yeah i need it !
Isint this useless for rom making without the boot.img? I'm no rom dev...but isin't it?
Any details on custom frameworks that Motorola uses, if any? I'd like to get my hands on the kernel source the Cliq uses as well.
sweeet. Cooking it now.

"should" not be since Blur is not a hero based rom. is still 1.5 based.

let them cook the rom before you start asking questions like that.
I'd think a ROM based from a Motorola phone would be even less compatible than Hero..
Anyway, I'd rather have a Blur/AOSP mix rather than a Blur/Hero mix.

I don't hate you!
Do we just install this through custom recovery then?
OH I see, so what if we dont go back to stock with odin?
I see two different versions here.
Can you tell me what's the difference in two? I know one is over clocked one by the name but I want to know what does other one does..

All you have to if you are on the stock rom is extract the zip and run the bat script and you are good to go. It is very easy to do. And restoring from odin is just as easy. It is what I recommend but it should work without

lol there is a lot of differences. it is faster has better battery life and overclocks to 1.2 ghz. the frameworks have been optimized for more performance and battery. also there is a lot of theming to remove samsungs ugly colors. it is not just a kernel. it is a rom that instead of flashing moves files in place.
Ok first off i want to apologize for the previous post about the Rom.
But here it is a huge leap for getting gingerbread on our g1s
i am not a developer i just simple tried and failed tried and succeeded
Now here for the unbelievable part this rom is fully functioning other than 3d launcher.
steps in flashing:
Wipe all recommended flashing superwipe
Flash the rom
Flash gapps
Done
Now second i realized it was not getting root access to fix this simply download superuser from the market.
this rom was made for the magic aka mytouch 3g
Links
Rom:
http://www.megaupload.com/?d=NKNFC89O
Gapps:
http://goo-inside.me/google-apps/gapps-gb-20110114-signed.zip
Now tht i think of it there is one other bug the browser likes to fc but i am sure you can download a alternative browser from the market. Let me know.
I want to try this but I don't wanna be the first one. :0 After someone else does it and posts on here about it, I'll be flashing this.
So it's a fully functioning stable rom!? And its gingerbread?
*i would be more willing to flash if there was some pictures of the proof of 2.3 and things working!*
If this is for the mt3g shouldn't it be posted in that section..

This is what I call a "high class problem". With so many ROMs to choose from, how does a noob like me decide. Aside from stability, we all probably have different wants and needs.
Can anyone who's checked out the majority of the available ROMs give the rest of us a rundown on the pros and cons of each ROM?
For myself, I'm looking for:
1. Basic
2. Reversible
3. No known issues with wifi, sms, battery drain, ciq, marketplace, etc.
Which one should I pic?

its close. if i have time this weekend you will see something drop. i have a few more tweaks i want to do before i consider it ready. internally, im already up to beta8, lol. i hope to have beta10 release as an RC1 for everyone.
From what I seen so far I seen no reason to try them though somebody has to or they never get fully debugged.
Some of the ROMs are AT&T only ..... sorry got SGH-I727R
Some of them do have Rogers ROMs but I read of Sleep of Death and losing LTE connection..... sorry too buggy and I NEED LTE or I would of got the Galaxy Nexus.
Finally what I really want is ICS and NOT ICS themed ROMs
None of them are for me but I check everyday when a ICS ROM comes out I will try it.
Finally I recommend you NEVER try Roms if you are not sure that you can restore.
I have backuped my ROMs, Apps and Data, APNs I am 95% certain I can recover from anything.
For that other 5% I have Odin and the orginal Rogers ROM
Just to agree with everyone else, you've got to try them out. There's no harm in it as long as you've done your nandroid back up, you're pretty safe when it comes to reverting back to your previous ROM and settings.
Reading the features and change logs for each of them helps alot... but it still doesn't give you a full grasp of what it has to offer until you flash and test it.
