Can I flash a different rom than the current one if have? - Galaxy S III Q&A, Help & Troubleshooting

Hey, I was wondering if i can flash a different rom than the current one if have. If yes, then what would be the best one to flash because the current one I have gets absolutely no updates and I want to flash one that gets the updates the day they are released or shortly after. Also am I able to flash it without have to do a wipe data/factory reset?? I’m new to this if you can’t already tell so as much help/advice as possible would be greatly appreciated ;p
Current version :
AP : i9300UBBLG2
CP : i9300UBLG2
CSC : i9300UUBBLG2
I was thinking about flashing an XXALE8 or XXBLFB

Check the link above for all the help you need, no need to wipe data if you are flashing to another stock Rom.

Hey
I flashed paranoid android 2.13 and have to say it's awesome and then flashed siyah kernel on it and now my phone is just a pleasure lol! I'm new to this whole thing too but I found it easy to flash the rom and kernel over clockworkmod recovery. Install goo manager and that will give ya the updates which u can flash over without wiping data. Unfortunately initially you will have to wipe to flash a new rom.

[Q] Kernel

Is it ok to flash a custom kernel on top of another custom kernel?
Sent from my GT-I9100 using xda premium
You dont need to revert on the original one before flash another custom. But you need to format dalvik cache and cache in recovery before flashing or you probably have a bootloop.
I suggest to make a backup of the rom in recovery, so If something goes wrong you can enter recovery and have the latest known working rom back in 2 minutes.
Please note flashing kernels always have a very small chance to corrupt your efs partition, its suggested to backup your efs folder before start play with roms and kernels. How to backup the efs, use the search tool of the forum

Thanks for that. I know how to backup efs. Can i just use nitrality instead of ADB? To flash ROMs does it need to be in a specific firmware like sgsl or is it ok to have different firmware from the base of a custom rom?

I know my english sux sry:
Depends on the kernel but usually it is listed in the kernel thread the how to (odin or clockworkmod), clockworkmode is already on your phone if you rooted it with cf-root.
Now, to enter clockworkmod recovery, just push volume up + home + power button until the S2 bootlogo appears, then wait few seconds.
About the kernel type, i always flashed any kernel despite of my baseband, the difference is not so big.
if something is not working, you can always youse the nandroid backup (the backup done with the recovery cwm (up+home+power) and get back to the previous rom with previous kernel.
Im not really in the kernel "how to" someone else can prolly give you more detailed info, but as for me, i flashed ninphetamine 2.05 and 2.1.3 in cwm and it worked.
But.. as always, the kernel developers got a how to install in their kernel thread, so just read those and be sure about if you need odin or clockworkmod, if you are not sure, DONT flash anything until you are sure on how to proceed or wich system to use for flashing, better keep an old kernel with a working phone than have a brick to hold the papers
PS: also almost all the roms on the S2 forum are flashable with the clockworkmod, only few (like the lite'ning) are flashable with odin.
Again, i know im boring, dont proceed if you are not sure, better ask 10 times instead brick your phone

Yes not a problem flash as per the custom kernel instructions .
Kernel can be changed within an individual firmware or custom rom .

Thanks for the reply guys. Coming back to my second question. What if i have KF1 and the rom i want to flash has a base of KI3, should i flash to stock KI3 first before flashing the custom rom or is it ok to flash a KI3 custom rom without flashing first to stock KI3?
Sent from my GT-I9100 using xda premium
The custom rom first, the kernel after.
I got the habbit to boot succesfully at least once the custom rom. If everything is ok i then flash the kernel. Better do 1 task at time.
You can decide to try the rom without change the kernel..and try a different one if you experience battery drain or other problems.

If i am on KH3 and want to flash a custom rom based on KI4 then i would flash stock KI4 and KI4 root first .
Custom rom flashed i will often try a different kernel later .

from my experience
I have found that when i upgraded rom from gingerbread to ics that most custom kernals work with these roms ie now running with xxlpw ics (from gingerbread) with xwlp7 kernal. from what i have read on other posts and threads i could swap kernal to siya or any other as the mega good developers have made them (hotswappable) interchangeable as previous reply said swapping kernal might give you better battery or solve overheat probs.
Eg iwas running darkys rom with siya kernal v?something my phone rocketed temp in short time so i swapped kernal for an up to date one (could have used older one) it solved problem.
Anyone feel free to correct explination im still learning too lol

help flashing roms

Im new to the whole SGS2 so needed a little help ive rooted my Galaxy and its on UK 2.3.5 stock rom my question is can i flash any rom i choose or is it like when rooting it when i had to get a kernel that matched.
The other thing is, is it worth buying Odin Mobile.
Cheers
Once you root your phone and have CWM recovery and not the stock one you can flash any ROM you choose.It has nothing to do with kernels but each ROM is based on a firmware so you should match your firmware to a ROM based on the same to start with and if you choose to stay with the same ROM then there are non-wipe ROMs that can be flashed over top without worries.Just be sure you read properly the install/flash instructions.Some ROMs need Odin to be flashed but most just need to be pasted to your internal-SD and then flashed in recovery mode.Ill leave a link below to my ROM where there is an instruction guide so you can read it to see what I mean.

It depends on how you have rooted ...... if as mentioned above you have CWM (means you have flashed a custom/insecure stock kernel) just flash a ROM with CWM Recovery like any ZIP but i'd advise you to reset the phone before that .... since you are on Stock ROM which is Odexed and all custom ROMs are deodexed you might end up in a bootloop also may i suggest CheckROM as it is simple to install and highly customizable thus i recommend this as your first flash......
checkrom thread:
http://goo.gl/eRCJt
else i use this site it's pretty awesome to keep track of things

Cheers to both of you, i think i will give checkrom ago as theres that many to choose from and im new to the rooted SGS2.

Going from Custom ROM back to Stock ROM SGP 5.0 INTL.

So there has been a lack of relevant threads that explain my topic issue for me so I have decided to make one for myself and for others in the event that this happens. So right now I am using RemICS-UX 4.0.4 but I wanted to use Eng-matts ergybit 2.3 rom, because I am traveling and I need video calling from skype, but when I tried to flash this rom with odin, instal via cwm it goes into a bootloop. I also tried to flash Ruebens Lewa os since it uses gingerbread as a base, then I tried to acquire the ROM again but I git a bootloop. Sadly I didnt back up my stock rom, so I'm trying to find away to get back to the stock rom so I can fladh eng matts rom again.
So if anyone has anyway for me to get to my stock rom please help
My device is the sgp 5.0 international

You need to install rj kernel if you have an intl device and entropy kernel for usa device . After you install the kernel you can flash erygit rom. Just replace the kernel
Sent from my GT-I9000 using xda premium
maybe you should flash the rom again with cwm and if you get a bootloop just reset factory/cache works for me : )
Go into CWM Recovery (if possible) and flash rumirand r14 kernel and flash a new ROM.
Suggestion: Next time flash a ROM via CWM Recovery, ODIN flashing is easier to brick than CWM, CWM is very safe and you can always reset the bootmode if you're stuck somewhere!

[Q] Cyanogenmod 9 install/help

hey guys,
so after reading the CM9 install guide, looks like I need to flash the stock ICS first. I'm currently using MIUI 2.1.7 which is still gingerbread.
I went to the stock ICS firmwares:
http://forum.xda-developers.com/showthread.php?t=1544487
But didn't see any North American or Canada firmwares, does it matter if I get the Argentina one, or can anyone direct me to a North American version.
Another question is, after I flash the stock ICS, will I still have my root and CWM?
Thanks,
eclipse

Incorrect, just flash cm9.
I can go from MIUI gingerbread, straight to the latest CM9?
So just follow the flashing instructions I guess, and skip all the other nonsense?
If you're flashing through CWM there is a long and complex process to flashing such a complicated ROM:
Step 1. Factory reset/ wipe cache/ wipe dalvik cache
Step 2. Flash CM9
EDIT: Remember to keep breathing whilst you do it, sometimes I need to focus so intently on the complex process I forget.
One more question, if I wanted to update CM9 via Rom Manager, to a newer nightly, would any data/apps/contacts be lost or reset, or is it just an update?
Nightlies are just an update, no need for a wipe.

Don't use rom manager, I've been hearing bad things about it. Just use cwm recovery. And no data would be lost, just don't data wipe / factory reset in cwm recovery

How do i get back to original rom

hi guys,
i have a samsung galaxy s2 (GT-i9100 - NFC), which i got from orange end of 2011. I the in jan 2012 got help from this forum to root my phone and change the rom from the original to:-
Rom & Build No: VillianROM 3.0
And' ver: 2.3.5
Baseband: i9100XXki1
Kernel: 2.6.35.11-ninphetamine-2.0.5+ninpo @ titan #20
Although the phone works okay, i'm beginning to notice a lot of slowdowns and regular reboots, so i want to go back to whatever latest google android OS the S2 can handle (rooted). I've forgotten what to do and would be most grateful if someone could please help me with the following:-
1. Whats the best software/method to backup everything?
2. What is the latest rom (original, but should not have a provider's bloatware) i can use on the S2?
3. Once backed up, how do i change from VillianRom to the latest/best OS currently available?
4. How can i root the original rom?
Thanks once again

For official stock rom, check
www.sammobile.com
And search latest stock rom for your region.
If you like custom rom, then there are so many roms on xda. I like omega and alliance roms. Choice varies from person to person

1. Depends. You can do a backup in CWM to image your device or you can use Titanium Backup Pro to just backup your apps/appdata and restore to new rom.
2. http://www.sammobile.com/firmware/ < Check your device/model here.
3. Well just so you're clear, There is no "best" its subjective. Also "latest" depends on what type of rom you want to flash like Sammy/AOSP/AOKP/CM/MIUI etc. To flash latest samsung do it via ODIN, to flash any other do it via CWM. All info you need is already on forum.
4. By flashing custom kernel via ODIN.
All your questions have already been answered countless times.
Thanks very much guys. I simply want a fast lean rom as some seem to be slow running.
Doesn't get better than this.
sendign the phone for warranty?
you will need to flash back the original rom and unroot your phone.
if they found your phone is rooted the warranty void, experience it before so be aware of this.
Let me thank you guys for advicing me. I am most grateful. I read your posts a bit late and in the meantime, I think i have bricked my phone as i've flashed Samsung's original FW (I9100PBVLP8_I9100PORALP8_ORA) from sammobile.com. I used Odin v3 and successfully flashed the phone, but it's simply stuck on the boot logo. I have even done the following:-
I've managed to wipe the cache partition, but the recovery menu has No advanced options. It says:-
ANDROID SYSTEM RECOVERY <3a>
reboot system now
apply update from ext' storage
wipe data/factory reset
wipe cache partition
apply update from cache
test redband fota[FS]
But i still cannot get it to boot. I have also tried to use an old nandroid.md5 backup i made, but odin reports the file as invalid.
I'm desperate guys, please could someone help me.
Download Mode and re flash.
Are you sure you are flashing the right ROM right? Check under the battery to see the Device Model.
If it's i9100, then make sure you are downloading a i9100 ROM.
Thanks very much for your advice gastonw - i have managed to fix the problem now by going into system recovery and doing a factory reset, so thank you.
Although everything seems to be working fine, i would have preferred a more newer 4.2 jelly bean rather than 4.0.3. Oh well beggars can't be choosers and all that, lol! I guess i'll have to re-root it again.
gastonw mate ur a star! I've installed the latest JB rom u posted earlier and i'm very happy with it.
Now before i damage it beyond repair, how do i root it safely?

Hi You could try this method http://forum.xda-developers.com/showthread.php?t=1501719 its quite safe so ether should work or wont, if don't no harm done as it doesn't need a insecure kernel.
I'm quite new myself @ this so plz use caution when trying it out.

Good to know man, enjoy it
About root, I've seen a couple of methods laying around the threads, I'm sure they're safe.
I still think that ExynosAbuse app is the fastest way to Root now (one-click).
Here's a vid. I never tried it tho.
Thanks very much for the links AnubuRe and Gastonw.
Gastonw mate, i have been playing with the rom you posted a link to. Don't get me wrong, it's great and very fast, but the downside is that it doesn't have a huge number of options to tweak etc. Now someone mentioned a rom called Neatrom, but i'm wondering what you can recommend? I don't want a bloated rom...i want a fast rom, but with some options to allow me more greater control over the phone.
Also, i know this is a bit off-topic, but can you recommend me a widget app, where i can quickly dial phone numbers i.e. by touching a person's photo?
