I have a kernel that i found that i want to flash. When you flash a kernel, does it replace a flashed ROM or do they combine?
Also, when you flash anything (ROM or kernel) does it replace the stock ROM or does it take a spot next to it? Can you make several spots so there can be more than one ROM? What is wiping out a ROM? If you leave a ROM, can you save your setting so when you go back you don't have to start over again? Can you back up contacts,messages, and apps from stock ROM and extract the data to the new ROM?
I AM CONFUSED

1. No, they "combine"
2. It replaces it when you flash
3. Yes, but its more complicated than just flashing multiple roms. There is an app but it doesn't support Sensation.
4. Wiping a ROM is just that, wiping your phone of the ROM along with all your app,data and anything else on the phone(SD card not effected).
5. Umm. I don't understand your question completely but yes flashing a new ROM over an old ROM will preserve your data but you can flash a different rom and expect it to work. For example ARHD-->ARHD(updated) is OK but ARHD --> Insertcoin wont work.
6. Yes, its called titanium backup. Look it up.
thanks. after reading this, I stumbled on radios. what are radios?

Radio is what gives your phone signal. which version works best for you will depend on your location and carrier so you will just have to experiment. its generally advised that you flash the latest recommended version stated on the rom your using

The only thing I'd add is that for:
o If you leave a ROM, can you save your setting so when you go back you don't have to start over again?
You can do a Nandroid backup from CWM recovery, it takes a snapshot of the ROM, Kernel, Data,.. You can then play with other ROMs. Then at a later date restore the Nandroid backup from CWM and you're back at the earlier ROM.
It's extremely important that when you play with ROMs you backup a working version. It saves a lot of swearing when you lose a nice working system unintentionally. It's happened a couple of times to me and it's a bugger.

ok since we getting more roms and have hellraiser over there opening the door. i have ALOT of nandroid back ups.
now having never had to actually use one of these i wanted to know somethings.
is a nandroid like a Rom, i just have to flash over another rom, or from stock and boom i have that Rom back with all my apps and info.
or do i need to load up the rom then nandroid on top of that for it work??
just have never had a use, but i would like to go back to some of my prior setups.
A nandroid is a system restore basically. If you fubar something and can get into recovery you can restore that nandroid to exactly where the phone was before. You don't need to flash anything just be able to get into recovery.

A nandroid will reflash system, data, cache - everything. The only thing a Nandroid won't flash is a kernel if you're doing a major change (e.g. Froyo to Gingerbread or either of those to CM7 - while it's also GB, it requires special kernels.)

ok with that said, you should flash the Kernel before the nandroid to make sure there is a compatible kernel there for the nandroid to use??
basically match up froyo roms and kernels and visa versa for BG before i decide to flash a Nandroid?

Yup, that would be a good idea - since if you restore the nandroid on an incompatible kernel, you'll have the phone be very unhappy. (Will refuse to boot.)
Much thanks E.........appreciate the time bruh.
this can be closed.
I completely failed here E, i tried to restore a nandroid. i loaded the Infusion GB Kernel then proceeded to restore the nandroid and just get boot loops no matter how i do it.
any thoughts??
Hmm I think I need to look at this later in the week. Starting to sound like Nandroid might be broken in red CWM.
i got it, but i had to load the Kernel - Rom - then do the nandroid. but that kinda of defeats the purpose in my eyes....lol
but yea, if you find something that would be cool to know E.
Hello,
I recently installed custom Jellywiz rom on my Verizon S3.
My question is if I have new custom rom versions or if I want to switch to a different rom, do I always have to go back to stock firmware and then install the custom rom or can I directly flash over my existing custom rom ?

New custom rom versions: Unless otherwise stated by the developer you can go ahead and just dirty flash right on top of the current one, but if you experience issues then i'd wipe data and cache and do a clean install.
Switching to a different rom: ALWAYS do a clean install (wipe data, and cache), i can't urge how important that is, while you may not have any issues whatsoever, you definitely could encounter issues because each developer may have different changes, and you don't want stuff to mix and match.

Thanks. So just flashing over existing rom after wiping data and cache will work. Will do that. I do not want to go back to stock rom always as that is time consuming.

You can flash stock roms in CWM, but be careful if they don't include a kernel. If you go from AOSP to Stock, you might get a boot loop unless you also flash a stock compatible kernel, and vice versa. Boot loop is easily recoverable of course, but it will scare new users

Finally was able to succesfully root my phone last night, and now I am wondering how to actually flash a custom ROM. I figured I'd start with Cyanogen since its the most popular and seems like a good starting point. So, I have a few questions.
1. How do I install the custom ROM? (Cyanogen in this case) Also, is this process the same regardless of what android version I have? (I'm currently on the stock 4.1.1 OTA)
2. Should I install a custom kernel? If so, is it the same process? Also, is my data wiped just the same as with flashing a custom ROM?
3. If I make a backup with Titanium Backup, will I simply be able to access/redownload my app data it if I redownload Titanium after I flash the ROM?
Any and all help is appreciated!

I'm sure everyone has their own advice, but I would say first thing you'll need is ROM Manager
Download the ROM you want and place it on your sdcard. Use Titanium Backup to backup your applications, and then restart your phone in Recovery Mode. When in recovery mode, make a backup by going to "Backup and Restore" > backup. Then do a factory reset and wipe your cache. Install the new rom and enjoy the addiction
Also...be careful making sure that any kernel flashed is compatible with the ROM you are flashing. If not you can brick your phone.

Hi.
I want to switch to ViperS 3.1.2 but have few questions before I do so. I've never done it before so I'm new to this.
Does it come rooted (or do all ROMs come rooted)?
Is there any instruction on how to do it or just flash it from .zip via the recovery mode (I have CWM 5.x.x installed already)?
And are there any bugs with it such as Wi-Fi problems/tethering, or calls (speaker)?
Also, what if something goes wrong? I've got a backup of my current ROM (stock), so do I just flash that one back or try ViperS' in case it was a mistake on my side?
Lastly, I've heard some people mentioning OTA updates. I'm assuming it's done in the same way as stock ROMs, so you just need Wi-Fi/working internet and the new update will install on its own, or do I have to download the update from here and then do it myself?
Thanks!

Are you S-Off or S-On? If S-Off then you can flash the zip directly from recovery and if you're S-On then you gotta flash 4EXT recovery first and enable smart flash feature and then flash the zip file.
There are no major bugs in the Rom except the ones listed on the OP of the official thread. Enjoy flashing.

I'm S-Off. I've had root earlier but I've installed SuperSU and accidentally pressed Clean SU which has pretty much wiped it. :|
Post your bootloader details to make things more clearer. Flashing a custom Rom doesn't need root access. You can flash it as you're s-off.
What Rom you're using currently? What firmware?

I apologise for not posting, although it may be a bit too late now since I'm already installing the ROM.
So, just wanna know now - do ROMs come rooted, and if I can always go back to stock ROM as long as I have the boot.img/download stock ROM from HTC site?

Most roms come rooted, and the rest provide root tools so you have a choice while flashing.
To return to stock look up ruu. An ruu + s on = your device as it came.
If you had flashed Firmware-3.33 before the ROM - you would have had no "bootloops" at all! The most important thing is to have Firmware-3.33

If you made a backup before flashing you should restore it, or else flash the ROM you had before flashing.
Then use "Titanium Backup" and back up your messages (your contacts are automatically synced with your google account, unless you saved them on the phone, but you can change that with the "people" app.
after you backed your phone up, make a full wipe, and flash the new ROM. Install Titanium Backup and restore your messages backup.
Good luck.

Get a download of the ROM you had before, and you can flash it normally. If you had stock, find a download of stock ROM (although Sense 3.6 custom ROMs might actually work too).

Oh no, I thought you wanted to flash viperS. Flash the ROM you had before flashing, whichever ROM that was (but flash that specific ROM, not a different one. My advice from the previous comment was if you came from stock ROM). If you flash the same ROM you don't have to wipe, and then you can back up your phone.

I hope you can operate adb, because the solution I found requires it.
Go to recovery, and use adbto pull the contacts database with the following command:
adb pull data/data/com.android.providers.contacts/databases/contacts.db
It might give an error for a protected directory (but I don't know since it's going to be done in recovery), if that happens, use 'adb shell' and then 'su'. then exit, and you have root access to the device (do it only if required).
Once you obtained the file, it should be on your adb folder. you need to open it with a database app which supports SQLite3 (I won't reccomend anyrhing since I've never used them. but from a quick search I found a few. and searching in the context of reading android databases would give some recommendations.).
Good luck
p.s - It's hard for me to believe this is the simplest solution. It might work, but it's not easy. So others might give better solutions.

tnx , if i try i can do it. i can operate adb easily . but a person said me to backup /data partition with recovery and then perform a full wipe and install viperS again then restore /data . do you have any idea abou it? can it help?
If i clean flash a new Rom but restore the data part from a backup i did earlier from another rom from recovery will it work? Im using TWRP recovery.
ive always had mixed results on this. if youre going from a TW ROM to an AOSP or AOKP rom, likely not. If you use TiB and backup your apps and their respective data, and restore them via the same method, that 99.9999% of the time works
