Quick question on ROMs - Android Software Development

So im pretty much an idiot when it comes to this, but ive rooted since i had my google g1. Im a little more serious about it on my vibrant and I recently flashed the blackhole 1.1 ROM. When i backed up my stock rom in rom manager it disappeared when i flashed my phone. This wasn't because of a wipe because all of my other files remained and i had a titanium backup set up. Now my first question is can i still flash back to stock? and if so, how? Also can i flash to other roms through rom manager without consequence or could it result in a brick? Do i need to flash back to stock before flashing a new ROM? sorry if I posted this in the wrong area I havent posted much on XDA, any help would be appreciated.

[Q] To flash or not to flash?

I've had my Fascinate for a few days now and absolutely love it.
So far I've been running stock. I've replaced TW with launcher Pro, hidden Verizon bloatware and rooted my phone. Bing isn't an issue because my homepage is set to Google. Should I stay on stock hoping that I'll get the 2.2 OTA soon or should I dive in and install custom ROMS?
What would be my primary benefits if I install custom ROMS? Any disadvantages?
I apologize if this question has been asked before. I tried searching the first few pages but couldn't find anything.
no replies?
I recommend you install clockworkmod, download rom manager,and buy the premium license, and use it to make a backup of your stock rom, then in rom manager you can download many roms, kernels and themes, and if you have any problem you can always use your backups to gwt back to where you want, just stay away drom vodoo, anyways when we get feoyo, we will get a costumized froyo rom from our fine developers here at Xda

AOSP Questions

Bear with me guys......haven't posted much on here, more of a lurker.
I have been following the AOSP Rom for the Fascinate for the last two weeks and now with the MMS working I would love to give it a shot. I have a couple of questions before I get started.
I am currently running ComRom 2.1 with the PBJ-50 Kernel. No themes or anything like that.
1. Is it safe to just do a data wipe and factory reset then just install the Rom over top of what I have?
2. Is there a Kernel and a Modem with the ROM?
3. Anything special I need to know if I decide to go back to another Rom (from what I have read just ODIN back to stock and Rom away)?
Sorry if these have been answered already.....I searched and did not find my answers. Thank you for your time.

1. I couldn't answer this with certainty as I haven't flashed it myself and haven't yet dug through the CM7 thread in development to put together correct steps
2. yes there is, but you can flash a custom kernel like OTB or the gingerbread leaks' (ec09) modem as I've seen these work though not for everyone
3. as far as I know all you need to do to go back is just odin back to eclair/froyo with the 2.2 atlas pit file and proceed from there
don't have any experience with CM7 other than what I've read so someone who's done it could probably shed more light on this

I just flashed cm7 today...
1. Data wipe, cache and factory reset should be enough. You need to download and install the 7/04 build, let it boot up and reboot back into recovery and then install the 7/13 build and then the gapps. There is also a modified cwm that you can flash to your phone that's been edited for cm7 not everyone uses it but I did and it works perfectly.
2. There is a kernel included but alot of people have better audio quality with one of the otb kernels.
There isn't a modem. But it seems like most of the newer modems are fine so your current one with comrom is probably good.
3. To do back to stock youll have to use a full odin package. But you probably won't want to anyway.

Thank you for the answers. Now I am more comfortable. Thanks.
Not sure how important it is, but I would wipe cache and dalvik as well. I used ED04 modem for a while, and switched to EC09 modem after everyone seemed to recommend it for the MTD roms. TBH, I havent noticed much difference between the 2 radios, they both worked well for me. As far as flashing back to a TW rom, check the sticky in the dev section:
http://forum.xda-developers.com/showthread.php?t=1124391
I am already running the EC09 modem. Have been for about a week or so. I watched as others have had good luck with it so I made the jump. I probably will stick with the EC09 as it seems to work fine with AOSP MIUI Rom that I want to try. I tried the EC09 on my wife's fascinate and it ran like crap.....kind of funny how two different build dates run to differently.

[Q] Reverting to stock ROM issue

Just bought new Atrix phone and unlocked/rooted flashed CM7.
Before flashing CM i backed up stock ROm which came with phone since i kinda liked it so i can use it later on maybe.
I tried to restore it now and in ClockworkRecovery it started to restore it but somewhere in the process it got stuck saying "cannot restore /system" and leave me no choice but to use custom ROM.
What can be the problem and how to solve it?
thanks
There's no way to answer this question accurately without knowing more information about your setup. Like for example what version of cwm are you using, what version of android were you using....

Currently i run latest CM7 (2.3.7) for Atrix and latest romracer's CW 5, all latest software.
about about loading a blur type rom? like alien? its essentially the same as stock with some upgrades and changes... maybe look into that as well?
nah, i'd stick with stock for a while..
Can anyone point me to stock flashable SBF for International/Europe devices?

[Q] Help With JB Energy™ Rom

Just recently flashed a friend's phone with Energy Rom. The rom looks amazing and is very well designed. There are just a few issues that he is having and I have not seen anyone else experience these problems in the tread. (Too few posts to post there)
Her camera is not working and I guess her Hotspot gave her a "timed out" message. . . . If anyone else has experienced this, please let me know if you were able to resolve this and how.
Thanks!

Are you on the 4.1.2 update? If so you will need to flash back down to 4.1.1 kernel because the new kernel is not compatible with the 4.1.1 camera

Energy ROM is based off of the the 4.1.1 build, the latest update has the XT907 at 4.1.2. So if her phone was previously on 4.1.2, then flashing this ROM could cause problems as the previous poster mentioned due to the new kernel. Not sure if the developer will update his ROM any time soon (which I loved by the way, and keep checking his thread for any updates),
also, Energy ROM can only be installed via SS right now, and given that the bootloader has been unlocked, I believe that all ROMs will be flashable via TWRP/CWM going forward - thus making SS obsolete for the XT907.
Here's what I suggest though:
unlock bootloader
install TWRP recovery
try out the DeadRage ROM, which is based on the 4.1.2 build: http://www.droidrzr.com/index.php/topic/17778-romretail-deadrage-v12a-05092013-412-base/
if you really want to stick with Energy ROM with working camera, then you still can:
flash back to stock (4.1.1)
root
install SS
unlock bootloader
install TWRP
install Energy ROM on Slot 1
backup Energy ROM via SS
move Energy ROM to stock slot via SS
backup Energy ROM via TWRP (basically making a nandroid, and this can be installed going forward as a backup)
uninstall SS
Thanks!

I will give the first suggestion a reply, if that does not work, the second. I will keep you all posted on results. Thank you!
Kernel?
Any clue of where I can find just the kernel I need to download and flash?
Sorry for coming across as a newbie, but I am used to other phones that have a bit larger of a community. Thanks again.

no worries - we all were newbies at some point in time.
I have not seen a thread dedicated to the stock 4.1.1 kernel, but I did find this:
http://forum.xda-developers.com/showthread.php?t=2017200
my advice at this point is to backup your apps/data via TiBu (and then copy that backup folder to your mnt/external1 directory).
so that way, after you pick your ROM, you can re-download your apps from the market (I always recommend doing this as opposed to letting TiBu restore them), then you can use TiBu to restore data ONLY from your apps. I do NOT recommend restore system data though when switching ROMs (however, I do restore WiFi settings and bluetooth pairings).
hope this helps.
All worked out great! I appreciate the help. I ended going with Energy 4.1.1 I have that stupid grateful dead image stuck on first power up due to rage. -Annoying!!

[Q] Can't get custom rom to load after install, keeps loading stock image

Thanks in advance to anyone who can help. I am new to this custom ROM stuff and am trying my best to follow all the guides, but I have no idea what I'm doing wrong.
I have a Samsung Galaxy S4. Android version 4.4.2 and Build version KOT49H.I337UCUFNC1, so I've been following the NC1 guides. I was able to successfully root using towelroot and verified that it worked using a root checker app. I then installed SafeStrap, backed up my stock image, and put two different custom ROMs on my external microSD card, Graviton (http://forum.xda-developers.com/showthread.php?t=2372742) and PurifieD (http://forum.xda-developers.com/showthread.php?t=2454205). After creating another ROM slot, and performing a factory wipe using SafeStrap, I installed Graviton and it went through and told me to reboot. However, when the phone loaded again, it looked just like the stock ROM again. So I wiped everything again and did the same with PurifieD. It gave me all the installation options of what bloatware I wanna get rid of, etc and also seemed to install successfully. But once again, when I rebooted after installation, it looked just like stock again.
Am i doing something wrong? I really want to use these nice looking ROMs!!
And if I can get that to work, it seems like I have no 4G connection, even though WiFi works. I'm assuming http://forum.xda-developers.com/showpost.php?p=50965837 is the guide I will want to be looking at to make it work?
Thanks for the help
I assume they are based on GNG8 AND GNG1 and you are running FNC1.
The rom based on stockrom is important too.
I suppose you downloaded Purified HD's v3.3? Because it is based on FNC1.
Try roms made specifically for your device to avoid problems and bricking. Experimenting without knowledge is also not supported here. Plus people are not responsible here for bricked devices or any weird thing that happens.
Towelroot worked for your phone as it is a universal app, made for S5 by the great @geohot, but works for many devices.
EDIT : Well I totally missed the i337 part. Thank you @Lennyz1988.

You need to read more carefully.
You have a I337 model. NOT an I9505 or an I9500. You can't flash other roms to your device. Stick to your model only the AT&T. Try what DeepankarS tells you.From what I remember your stock rom needs to be the same as the rom you are trying to flash.
Thanks for the assistance fellas. And yeah, knowing that I was looking in the wrong threads would have been a better start and I'm lucky I didn't permanently damage my phone. Thanks again for the heads up.

Anytime. But you can always port roms to your phone. There are a lot many ways to port a rom for your phone
*A bit of perfect copy paste skills required for that
