So I'm familiar with flashing, just not with the tablet. What's the accepted method for flashing from 1ROM to the next? With my phone I generally flashed back to stock using ODIN. Is it OK to simply jump from one ROM to the next?
Thanks guys.

The same method for your phone is generally the best way to do it on a tablet as well. You "can" jump from one to another, but you always run the risk of file pieces getting left behind or random little bugs cropping up and such. For that reason, it's always best to do a full wipe, factory reset, wipe cache, wipe dalvik cache, and then flash the new ROM.

Formating /system, /data and /cache is sufficient. Factory reset could compromise your /sdcard and /sd-ext (if any) data, depending on the custom recovery you're using.

I just want to be clear, im to understand that all I really need to do is a fact data reset, and wipe everything from recovery? if thats all there is to it then freaking sweet. flashing to ODIN and going through the motions gets annoying.

I have always done this with the express intent to wipe everything clear and reinstall all apps and data fresh once I'm on the new ROM, but this has never messed up my CWM.

Yeah, I feel your pain. I love my SGSII and my wife has my old Captivate, but the ODIN stuff all the time did get kind of annoying. Luckily ODIN and a homemade jig are a lifesaver if you ever screw anything up though But yes, flashing to a new ROM on the tablet is pretty simple and doesn't have a few of the extra steps you have to do on certain phones. Just back everything up on your PC first, then I generally like to type out a list of all the apps I have on the tablet to redownload afterward, then wipe it all and flash the new ROM, then start downloading stuff from the market again.

Sorry, this might be kind of a noob question, but i see build 23 is out for CM7. If i flash the new build, do i need to totally set up my phone all over again?
My last experience with CM ROMS on my G1 was that if you are upgrading to a new CM version a wipe is recommended but not necessary. However, if you do not wipe and experience problems it will be the first troubleshooting step suggested to you
YMMV on the MT4G builds, but that's how it worked with the G1

Thanks. Ugh, i didn't even think about that when i flashed CM7. Seems like it is a real PITA to wipe every time and have to configure all the settings again.
I had good success on my move from stock -> Ice Glacier (un-crapwared stock) by making a full TitaniumBackup of -everything- and then restoring it app by app (along with settings). They are similarly built ROMs, and it worked well for me with minimal downtime. You may want to consider trying that if you are just changing between CM flavors, as I would presume they are mostly backward compatible with a few fixes/features here and there. At worst it may leave you with just system settings to redo.
When i flash a new CMNightly all i do is wipe the cache and the Dalv/Cache and i've yet to have any problems. If you are worried about wiping and restoring everything. you might want to look into Titanium Backup.
thanks. I flashed without wiping and it seems to be fine. I was worried more about my system settings than apps.

Wiping the Cache and wiping the Dalv Cache will not reset the phone. Only a full wipe will do that.
To my understanding, a "full wipe/factory reset" in Clockwork Recovery will only clear /cache, /data, and Davlik cache. /boot and /system will not be touched. Some users moving from Froyo to Gingerbread have had problems with /system, and a wipe of /system (from within Clockwork Recovery or from adb) has solved some problems for people, beyond what a full wipe can do. Discussions are in the CM7 thread in the Application Development subforum.
I know, most people refuse to search for anything.
i usually wipe the Cache and the Dalv Cache when updating nightlies, but several times i've wiped nothing and just flashed the new one on top and its always worked just fine for me
I always do a full wipe when installing roms. Setting it up each time makes me think its a whole new phone which is cool.
You do NOT need to wipe when upgrading to a new version of the same ROM. I've probably flashed 10 no-wipe updates of cm7 on my phone and it's still perfectly stable, no force closes or anything.
Boot into recovery and wipe cache and dalvik cache before flashing. Give it a few mins to "settle" on the first boot, reboot again and you're good to go.
Worst-case scenario you'll just wipe and reflash anyway, and nothing lost.
Hello,
I flashed CWM and did a full system backup/system wipe/cache wipe then installed xboarders 1.2.2 rom for the first time. I'm rooted! woohoo! I want to install eaglesblood new rom now. My question is when installing a new rom is it recommended to do a full backup or is one time enough? Thank you for any help as I am a newbie at this.
I always keep at least one or 2 backups of setups that I know work. That way if I screw something up while tinkering with my phone I always have a working backup to fall back on.
So yes, its recommended to keep a good backup on hand. You don't necessarily need to backup every time though. I just make sure I backup my texts before I flash anything. I hate losing those.
What you DO NEED to do EVERY TIME you flash between completely different roms is do a full wipe before you flash the new rom. If you're only updating to a new version of the same rom then a full wipe isn't necessary.

Thanks for your help! Also, when doing a full wipe do I need to do a dalvik wipe as well in the advanced settings in CWM?

I always do. It certainly wont hurt anything if you do. Just remember the first boot after clearing dalvik cache usually takes a little longer than normal because the phone has to rebuild the dalvik cache. Don't panic if it takes a few minutes even to boot. After the first time it wont take as long.

Does anyone have a zip that will wipe my phone clean so that I can install a new ROM? I have one for my GS3, but I was unable to find one for my One X. Even with a Google search.

You'll need to find the RUU for the firmware that your phone is currently on. Download the ruu to your computer. Plug in phone and boot into fastboot. Run the ruu on the computer and it will bring your phone back to 100% factory status.
It won't wipe your sdcard though. To get it squeeky clean, you'll need to format the sdcard.

I think he's talking more along the lines of caulkins format all zip.
Try searching for that. It formats system, data and cache.

To be clear, you don't "need" any such zip in order to install a custom ROM. Some people believe such "Superwipe" zips are a cleaner way of doing it (and may also be useful if you are experiencing bugs after a ROM flash). But I've never used anything of the sort, and never had any issues.
Just wipe cache and Dalvik, then factory reset in recovery (do not factory reset in bootloader, as this corrupts the SD). Then flash the ROM. No need to format system, as this is done automatically when you flash the ROM.
By that logic, no need to wipe cache or dalvik either since factory reset does that. I find wiping system provides peace of mind and one thing to cross off when troubleshooting buggyness within a Rom.

Yeah plus I'm sure I've seen ROMs that don't wipe system during the install script. I always wipe system, for peace of mind, seeing as it only takes a second.

Not sure, but I don't think that is true. I thought all factory reset did was format the /data partition (delete user data).
Also, wiping cache and Dalvik is completely harmless. They will just rebuild themselves when you reboot. There is literally no reason not to wipe them, in any number of circumstances. Wiping system . . . not so much.

I've seen this on another device, but haven't seen or heard of it on this device. Although, of course I haven't flashed every ROM available.
Sure, it typically doesn't hurt to do wipe system. Although I've seen the all-too-common instance of the n00b randomly wiping things (including system) and then asking "why won't the phone boot" (umm. . .because you wiped the OS). Thus, I normally refrain for recommending to wipe system (at least without making it clear what that actually does).
In any case, my main point is that all the required wipes are available in recovery, and no special wipe "zip" is explicitly needed (although might help in certain instances, as I've already mentioned).
Isn't dalvik kept in /cache or /data?

I'll be honest, I did use one for a while back when I used twrp. While it is kinda pointless, it is a lot faster adding it to the zip install list than going through every wipe/format option.
OT: I feel like I'm the only one using philz touch recovery. Anyone else using it? It's got a lot of nifty features.

I had to look it up, but apparently it is on /data. So Factory Reset should in fact wipe it.
I've probably always though of Dalvik as something that should be wiped separately, since you should (at a minimum) wipe cache and Dalvik when doing a "dirty flash". Than I just do it by habit when doing a "clean" flash.
As I already mentioned, most of us will likely agree that there is no harm in wiping things that are going to be wiped anyways "just in case".
As long as you aren't one of these folks that wipes /system, then asks why his OS is gone.
Flashed several ROMS in my life and have not always wiped all data. Mainly i do dalvik and cache. My phones have always work. Now i have a Razr HD with an unlocked BL with TWRP loaded. I cant seem to get past the initial bootup screen no matter what ROM i flash. What am i missing here guys? Do i need to check the "factory reset" in TWRP along with Dalvik, system and cache?

"By golly that worked! It booted up fast as well. It must lie with the formatting your internal storage before flashing the 4.3 rom. I tried something similiar to this but I was already on a 4.3 rom that wouldn't boot and I formatted the sd card then tried flashing it again and it booted again for the first time but wouldn't the second. So if your having trouble do this:
Restored stock 4.1.2 using Matt's utility
Rooted with Matt's utility
Put 4.3 rom and GAPPS on external SD
Fastboot flash CWM 6.0.3.5 (or install via Matt's utility if you like)
Wipe data/factory reset
Wipe Cache/Dalvik
Go to mounts/storage and format /data and /data/media (/sdcard) **Back up anything in your internal SD you want to keep before doing this!**
Flash 4.3 rom

Flash GAPPS

Boot up and setup rom

Please explain this further to me. My problem is with 4.2.2 ROMS. The fix above is for folks having issues with 4.3 ROMS. Are you suggesting that doing this will also fix my 4.2.2 problems? This is also CWM while i run TWRP. I did a quick look and the two are setup a little difference. I played around with those highlighted instructions and almost accidentally wiped my only backup of my previous state. I actually thought i was toast but somehow i reloaded and went back to my old backup state.

i could be wrong, but in my opinion having the exact same issue even though its a different version, one of the 2 fixes in that thread should work.
the first fix likely doesn't directly apply although i suggest you ensure you have the latest version of your recovery of choice found here http://www.mediafire.com/download/tt7cwwua49n24uv/Razr_HD_Recovery_Flasher_V7.rar
second fix (backup ALL data you don't want to loose first as noted above), then do a full wipe as listed above, not just a fdr that doesn't wipe everything on the internal card.
the problem at this point is, you are assuming it wont work because of version differences, i am assuming it will. until you try it, i don't see any point in exploring other options, if there are any.
Dirty flashing when you go to different ROMs is generally not a good idea. Even on 4.2.2, it leaves residual data behind. There's a reason that the devs talk about doing complete wipes in their ROM threads, and there's a reason that they tell you not to talk about bugs unless you use their install directions.

I used to flash things like Liquidsmooth and my phone would fly. Now when I flash GPE or a CM based ROM, it hangs and lags sometimes. Anyone have any similar problems?
Would also be a good time to ask, will wiping internal storage in TWRP delete recovery so I can't flash ROMs?

No issues here... To answer your question... no It will remove your backups if you stored any there. Once you have installed twrp it will always be there unless you change it.

That's your whole problem right there.
You are reluctant to wipe /data? You HAVE to do it if you go from one rom to another. Also called a clean install.
If you go to the Wipe menu in TWRP and just swipe the button it will wipe cache, Dalvik and /data except /data/media/ which is where your personal files live. It will wipe you apps and their settings, but you can backup those in TiBu and restore them afterwards. Do not restore system settings from TiBu though!
Give your phone a break. Do that factory wipe I described above, then re-flash your current rom and I can pretty much guarantee it'll be night and day.
This phone is so fast - a shame to gum it up
