First time flashing ROM....help? - Verizon Samsung Galaxy S III

So Im ready to go through and flash a ROM finally but I just want to make sure I do things right. I have clockwork mod and have made a backup already. After I download the ROM do they come with different kernels or can I use stock? Also what is a good stable ROM to start with? Id like to get a jellybean one but I have seen one with a lot of bugs still. Any help would be great

9Start with clean rom + clean kernel . This is a good dose to start.
Once you feel comfortable and would like a higher dose
Then move to beans or synergy ..here you can mix and match kernels and roms
Beans comes with imos kernel
Synergy comes with ziggys kernel
Mix and match kernels for your perfect combination
By now you are probably craving a rom with daily updates
Cm10 paranoidandroid AOKP are 3 roms with daily updates
Here youll find imos aosp kernel and kt kernel that go hand in hand with aosp.
By now the first leak of VZW touchwiz jellybean should be hitting the interwebs to take care of any addiction that may ensue. Happy flashing.

Thanks for the help. Now if I were to cwm back to my backup of stock does that reinstall my stock kernel?
Tap'n

yep

So do I flash the .zip of the ROM first then the kernel then reboot? Cause I tried beans but you can use stock kernel with it cause my bootloader isn't unlocked

Just download ezunlock from the market to unlock your bootloader. No reason to keep it locked.

Well I heard if its unlocked then it can brick you if you OTA. Or does the lock button actually re-lock it?

yeah it can, just never accept and OTA and you'll be good. Plus since you want to install custom roms, your going to need custom recovery. These block otas from happening even if it was automatically pushed to your phone.
The lock button does relock it.

If you're going into custom roms there's not really much reason to accept OTA anyway.

almost all custom roms dont allow the pop up about a OTA anyways so you should be clear

Ive used Synergy v1.7, and CleanRom 2.0/CleanKernel 1.0 is way better and smoother than Synergy. Im thinking about upgrading to Beans..but im not sure I want to do that yet till all the bugs are worked out of the different Roms to choose from now.

if you mean any custom roms that are based of the tmous stock rom? then not yet.
if you have a custom rom on and need to flash to original you can always do a nandroid restore of that rom
if you need the RUU for whatever reason get it here http://forum.xda-developers.com/showthread.php?t=1074559 the latest tmous is the 8th one down

what rom did you flash that this occured?
i havent flashed any roms yet since im waiting to see if there is one created based on the sensation4g stock rom. plus the stock with no bloat has been wonderful for me so far.
i'm gonna wait another week as the devs should have their roms/kernels updated a few times with bug fixes then im gonna try and flash then.
best bet is to ruu back to stock with the link posted above. gives you stock tmo rom with the original bootloader only s-off. from there you can root and run stock rooted and debloat yourself.
I'm about to get the sensation. Is the stock rom pretty good with a simple debloat?

[ROGERS] I finally decided to install TWRP and the CM9 alpha

Do i just unlock my bootloader, then fastboot install recovery and start installing custom roms?
Or do i need to change my CID, update to the latest ATT RUU (1.85?) then unlock the bootloader again, then install a recovery and rom?
i'm still on stock Rogers 1.73
The first one.
awesome
so people were only updating to 1.85 becuase there weren't any custom roms yet right?
when custom roms came at first we had to update to whatever base the rom was using.
Now we can install kernels along with the roms so there's no need to do that anymore

So we need to install the roms, along with a kernel update.zip?
Or does it all come packaged like it does for other phones.

Former Droid X User Needs Help Transitioning

I'm making the transition from my old Droid X to the VZW Galaxy S3, and I have a few questions. The flashing process between these two phones are quite different and perhaps another ex-Droid X user (or just an all around knowledgeable person) could help me out.
1. To my knowledge, we were never able to flash Kernels on the Droid X because of its locked bootloader. So how does Kernel flashing work? Are there certain kernels that only pair with certain roms, or can you flash any kernel you like with any rom? I have a feeling it's the former, as I've already seen kernels categorized i.e. Touchwiz Kernels or CM10 based kernels.
2. With the Droid X, all roms were flashed using CWM. But with this phone that's not always the case right? Some may require a kexec method or even a custom recovery image, correct?
3. I've seen a few roms recommend backing up IMEI / MEID / EFS data before flashing. Is something I should consider doing whenever I flash, just as one would do a nandroid backup?
4. I've seen a few threads mentioning flash count, resetting flash count, etc. Should I be concerned with flash count? If so, why?
5. With the Droid X, before you could flash a rom, you had to make sure the firmware you were on was compatible with whatever rom you were trying out. For example, if you wanted to try cm7 you had to flash over the stock froyo kernel. If you wanted to try miui you had to flash over a stock gingerbread kernel. However, it would seem, with the S3 you can flash any rom (whether it be an ics rom or a jb rom) over stock 4.0.4. Is this correct? Can you flash an ics rom over the top of a jb rom? Or do you always have to revert back to ics stock?
6. Is Odin the Samsung equivalent of rsd lite?

1. Flashing kernels has been made as simple as flashing ROMs
2. kexec is outdated since the bootloader got unlocked. You can also still use CWM on this or there's another recovery that people like called TWRP (Download an app called EZ-Recovery from the play store, youll need it to flash any recovery)
3. Losing IMEI is a royal paiin in the arse, but it's rare. Either way you want to back it up. I believe the guide on how to do so is in the Development Forum.
4. I haven't tripped the flash count. Basically all it is is a way for Verizon to tell if you been f'in with your phone. I Believe that only AOSP/AOKP ROMs can trip it, not stock ROMS
5. It's a bit simpler flashing between ROMs on this phone. Just wipe data/factory reset and flash away. For the most part.
6. Yes it is basically.
Check the guide out in my sig, it'll explain how to do most everything in detail.

To Elaborate on this just a bit, yes it is as easy as flashing roms but you were correct in saying that there are aosp kernels and there are tw kernels. just make sure the os version (ICS, JB) and the framework (TW, AOSP) match your rom and you are good to go!

Thanks Brian and Relentless. Going to cut my teeth on an easy TW rom for starters, probably Synergy.

If you are just getting your feet wet with tw roms, you might consider giving Bean's a try. I've been using Build 9 since it dropped and it's smooth.
imo, it's themed just enough to not look like a straight tw rom, the performance is great and the battery life is fantastic as well.
I've tried synergy once or twice and was never quite completely satisfied with it.

I haven't run CM or MIUI or any other AOSP ROM on this phone so take this with a grain of salt;
If you want cool stuff and constant bugs/lack of normal features go with the AOSP....
If you want some cool stuff and a nice stable daily driver... go with the TW ROMs. I've been running Synergy since 1.2(or 3 I cant remember lol) and I love it. Everything works on it, it's stable, and it's currently being ported to Jelly Bean so I can't wait for that shtuff. Eschelon and the rest of his team are good about listening to feature suggestions/requests too when they got time so more and more will be added.

The moral of the story...Try out a few different roms What is amazing for one person might not be for the next. I'm flashing new roms every few days because I always want to see what else is out there.

Yea I had beans for a little while... I honestly cant remember why I switched. I was just suggesting he stick with the TW ROMs period cuz I dont feel the AOSP ROMs are anywhere near stable enough yet.
Don't want to hijack OP's thread, but do any of you know how to check flash counter?
I will be getting my FOURTH sg3 this week, and this is the first time I will be returning a phone that I had rooted/unlocked/rommed. I'm all back to stock, just want to make sure I don't get a bill for $600.

How "rare" is it to lose the IMEI after flashing? And is losing your IMEI a possibility flashing any ROM or just certain ones like CM10 or AOSP, or are TW and Stock roms susceptible to this as well?

I honestly don't know. One of the devs for Synergy ROM said something to the effect its "a weird Samsung reboot code and so the phone automatically restores a bad backup of your IMEI. It's a fluke thing"
It's 100% random when flashing anything I believe.
If u use the synergy Rom to flash it automatically has a script to back up your meid number and stuff. I've flashed synergy official cm10 nightlies without a hitch. Just make sure that u obtain root and unlock the bootloader and flash recovery. Thus far I've had no problems. Btw synergy Rom is the best one out there. Jellywiz is a jb Rom it is awesome but only thing that doesn't work is sms at the present time. If u want to back up ur meid best tool to use is qpst just Google it. Also all in one tool that has been great for me unlocking obtaining root and stuff is Verizon gs3 casual tool. In order to use that tool u mist have java se framework which u can find at the java website. Any questions feel free to shoot me a message! Good luck!

Just to clarify. Synergy is a stock tw based rom and CM10 is well a cm based rom. Two different monsters and roms entirely.

I found this thread which looks like the Synergy guys made a script to backup IMEI. I gave it a go and was succesful in backing it up. Seemed much easier than the QPST method. Don't know if it will actually restore, but hopefully I'll never have to find out.

[Q] CleanROM ULE Question

I have tried to use CleanKernel 1.2 & Lean Kernel .10 on this ROM. After installing both kernels I seem to get a huge "non responsive" delay after the screen shuts off and the lock screen appears. Is this because the base has been updated to VZW G7 OTA and Kernels are for an older base? Or is there a fix that I am missing? I have ran both kernels with no problems on older based ROMS.

Rule of thumb: Never flash a Rom made for one base on a different base. You have to wait until dev makes one for the new base. Many things could go wrong. Consider you're lucky.

Actually, most of the times, you can flash a kernel that's based off of a different source base on a different base ROM as long as they are the same Android version (same framework). VRALG7 did not change much other than some of the apps and on the kernel side, I don't believe anything has changed. That should go true for radio too. For the OP, did you come from wipe everything and flash clean? Also, I am not sure what kind of modification the ULE went through but it may be lacking some libs or ramdisk since the rom is so damn light. Go and pull the boot.img from original ULE and see if the original kernel causes the same issue.
I installed the KT747 kernel. It runs GREAT with this ROM! No lag, super smooth & fast. Thx for the replies! KTweaker app is Awesome! The unresponsive / frozen lock screen is gone! CleanROM ULE + KT747 = Winner!

I agree! Scott updated Clean ROM yesterday to 2.5 which is based off of the new G7 baseband. As Scrosler states in the OP, a new clean kernel is not available yet, so when you flash the new 2.5 you will be on stock. It's worth updating though! I'm sure an updated/upgraded kernel and mods will be out soon enough.
I had that same issue

SO what I did, made surei have no cpu apps runnung to be set on boot ( major problem when using titanium as a restore agent )
Then I flashed scotts clean kernel ( whatever the lastest edition is ).
Then right then and there wiped cache, and dalvik and then fixed permission.
THEN HERE IS WHERE ITS VERY IMP. I LET THE PHONE SIT FOR 10 MINS BEFORE TOUCHING IT AGAIN.
Now i am running smooth .
This is on .lk 0.9 which is essentially the same as lk .10

[Q] COming from Bionic, to S3....confused ?

Hey guys, I have had a Bionic for the past 18 months or so....forgive me if my questions sound silly....
Recently, I was given a S3 to use. Before I take the plunge and get it activated, I was tryign to learn about the ROMS etc out there.
- I see there are TouchWiz ROMS and AOSP roms. I'm assuming the TouchWiz ROMS are based on stock rom just tweaked and debloated and teh AOSP ROMS are the ones built from scratch?
- I see there are kernels around....same, AOSP and TW. Is it safe to assume if I use AOSP, I need to get an AOSP kernel? If I install for example the latest Liquidsmooth....do I have to do the kernel 1st? or does the ROM have the kernel built in?
- Do I have to unlock the bootloader? Or is that what the kernel does?
Again, sorry for the dumb questions....my Bionic was simpler to do...with less options....
Thanks in advance

1. AOSP is the original Android OS untouched by any company. Touchwiz is Samsung's version Android.
2. You don't need a custom kernel but it can optimize your phone for increase in battery life.
3. All ROMs have kernels built-in they have to or else it won't work .
4. You must unlock the boot loader in order to flash anything.
Gotcha..!
Thank you!
So is it safe to assume, you flash ROM 1st, then you flash kernel? At 1st glance, I like the Liguidsmooth ROM, but people are also raving about the KT747 kernel. SO I would have to flash his AOSP version...
I have seen some radios also...Is that advisable to do?

Yes that is correct but you must first root your phone. The bionic had a larger margin of error when it came to rooting.
Yes, 1st thing I'm going to do is root and unlock the bootloader....
One last Q...
I see people are having GPS lock issues on some ROMs (eg Liquidsmooth), compared to stock. Would that be a kernel type off issue? Would updating the kernel to the KT747 fix this?

It is a ROM issue so the devs have to make a fix for it.
