I've searched out and read alot about rooting. I've down loaded the required files. Read and re-read as much as I can about rooting, flashing, recovery etc. I do not claim to understand it all. I'm still in my Buyers Remorse period so I won't root until thats over.
I've read from end to all, all the Custom ROM threads on this forum. EaglesBlood makes the comment...Wipe wipe wipe ....and he lists several things to wipe.
I've gone back into rooting and flashing guides and cannot find anything about Wipe.
I rooted only 1 time in my life....on the Nexus One....but don't recall using any wipe command.
I searched over in the Android forum for any kind of guide that would take me from Root to recovery to flash to update....and answer the wipe question for me.
I've flashed and wiped for years on Windows Phone....and spent the time in advance to understand the process and the steps ...before I attempted it. Want to be as sure with Android...before I step in...because...lord help me....if I brick the device, I'm gonna have to go to a Sensation....because G2x's aren't back on the market yet....and I really don't want to do that....I'll have to take back everything I said about the sensation if I do....
Does anyone know of a guide that goes from root to recovery to backup to flash and includes the tips and tricks like....wipe, when to wipe, etc?
TIA
If you want to root there is a topic in dev section called superoneclick
For clockworkmod(backups, restores, rom and kernel flashing) check out the nvflash topic in dev section
For all roms there is usually instructions as what exactly to do in steps.
Hope this helps. I would post links if I was on my computer sorry.

I will help answer your question. When you root an android phone you are installing files that give you the ability to modify your rom, and recovery. These files are stored in a separate partition on your phone that is hidden from the phone you will not need to wipe when just rooting your phone.
If you want to install a custom rom you will need to first flash a different recovery for the g2x you need to use nvflash. This process once again you will not need to wipe the phone. Whit this recovery you can make backups of you phone and does not require a custom rom.
If you want to then install a custom rom use the new recovery to make a backup first that way you can restore your phone if anything goes wrong.
Now after your back up and after down loading what ever new rom you wish to use it is always suggested to wipe your phone. Wiping clears out all your personal files from you rom partion making it easier for the new rom to install the new files needed for the rom and to modify any old ones.
I hope this helps explain and clears ups your questions.

Moved to proper forum.
There are a couple of options in the recovery menu that let you wipe data. When I boot into clockwork mod recovery you can choose to wipe all user data, cache, dalvik cache, and battery statistics. They're located under different sub menus but they're all there. When your ready to flash a rom make sure you have a backup, then wipe all user data 2 or 3 times (thus the Wipe Wipe Wipe you were referring to), wipe dalvik cache, and then flash. Some people recommend wiping battery statistics too but I don't know if that's necessary every time. Once you've wiped everything sufficiently then flash your rom. Wiping just ensures you're starting with a clean slate.

Thanks All,
Right after I posted this, I found unlockr.com. Not that he looks like 'The' expert, he puts everyones stuff together in the same place. I saw where the WIPE WIPE WIPE comes from.
I had already used this superone click thread on this forum to gather the files...but wanted to see the steps in action....the vids on the unlockr site show me the steps quite nicely.
thanks all for the feedback.!!
"Wipe, wipe, wipe" refers to wipe the data, cache, and Dalvik cache, which is done via CWM.

.. that does the equivalent task29 we used to do in WM6.5 ?
What task 29 used to do, is wipe the whole device, rendering it non-bootable.
So everytime you wrote a new rom on it, it had fresh system files on it.
Is that possible on android, or is it not needed ?
I mean wipe data/wipe cache/wipe dalvin on cwm is enough to wipe the system clean ?
#1 wrong section
#2 do
- factory reset
- wipe cache
- wipe dalvik cache
#3 do #2 3 times

We do #2 multiple times, cuz cwm and amon_ra showed that some times for some roms, on wipe isnt enuf
You don't need to make the phone unbootable; it's not necessary to do that to flash a new rom.
The clockwork wipe/factory reset should be good enough for any phone. That also wipes the cache and dalvik-cache anyways, so the other steps are just being a bit anal, but don't do harm, and some do think they're necessary. (FYI - I do them too. LOL).
IF you ever want to TOTALLY wipe the phone, including all personal data, apps, and sdcard contents, the quickest and easiest way appears to be just run the fastboot oem unlock command on the phone again. Total wipe of everything outside the /system partition.
There is something like a task29. The only place I know I exist is for the G1. It is called superwipe and is flashed from recovery.
It wont work with the nexus s?

Hm i didnt think of that. Last night i did a format of my sdcard and a odin restore into 2.3.1. I had weird behaviour before with all the nightlies and the different kernels and stuff and after 3-5 wipes of cwm i would still find trash in my phone. Everything works fine now after all that hassle, but i loved the task29 back in the days. Heck i got my hd2 out of the drawer just to task29 it.

i looked through the forum and didn't find this exact question so i'm sorry if it's been posted before.
basically what i'm wondering is if i have a ROM installed, let's just say one of the new ICS ones, and a new release of that ROM comes out, is there a way to upgrade to the newer version without having to install all my apps and stuff again through titanium backup? i hope that makes sense. in other words, is installing a new version of a ROM that you are already using going to be the same process as flashing a new ROM entirely? that could get annoying with newer versions of ICS seemingly coming out twice a week.
thanks in advance!
It's recommended to wipe and reflash, but I just flash over top and if there's problems I resort to wiping. Clear cache and dalvik and just flash over top, your apps will still be there. But if you do it this way, you should not report any problems
Sent from my Inspire 4G using Xparent Blue Tapatalk
Probably could have used search to find this. But typically, unless the dev say to full wipe, when an update comes out for the rom you are using you can flash the update over the older version without a full wipe. You are still required to clear cache/dalvik to do this. If anything that was working before does not work anymore after you have flashed the update over the older version, then you should go back and do a full wipe and flash the new version. I personally always full wipe when flashing a newer version.
Sent from my Inspire 4G using xda premium
It all depends on the ROM and what is updated. Seriously you have to go by what the DEV says in his thread. Some you can update without wiping and some you have to wipe. Others will automatically wipe for you. Best advice is to read the DEV's thread. They should all give you this info. And if you looked over the first few posts of his thread you really wouldn't be asking this question here.
Some mods have the cache/dalvik wipe built in, so just make sure you read through the thread for whatever mod you're trying. Wiping it twice won't hurt, but just wastes a little time.

really? man. I'll make this very simple for you.
1. put rom on root of sdcard
2. boot into recovery
3. wipe data, cache, dalvik cache
4. install from sdcard the zip file
5. reboot.
almost all ROMs except for the PD98IMG.zip stock ROMs are flashed with the above method. Not all ROMs require a full wipe (data, cache, dalvik cahce) when upgrading within the same ROM but it is recommended to do so to avoid any issues. If you're switching between different ROMs, it is required to do a full wipe. Search my good man.
All - I recently rooted my phone. I was excited to start experimenting with ROMs and then got completely overwhelmed.
It was hard to figure out the differences among ROMs, and when I tried to learn how to flash them and try different ones I felt that the instructions for flashing ROMs in the individual threads seemed written for people with a lot more experience than I have.
When I started seeing terms I didnt understand, talk of flashing modems, etc. I totally got intimidated and gave up
Can anyone help direct me to the best guide on this site (I have searched around) for a beginner to experiment with ROMs? Easiest to follow instructions? I followed the ROOT instructions on this thread and found them pretty easy to follow step by step.
Also I know we arent supposed to have "best of" conversations, but are there any ROMs that are easier to install than others, where it might be a good starting point to experiment and learn?
I have Titanium backup but I know people talk about things like "nandroid" and while I have found threads that mention these things, I am really struggling to confidently put it all together.
Any advice or guidance? Is this too much of a total n00b question?

Once you have a custom recovery, you are golden.
All you need is an ICS radio for any jelly bean ROM except for the leaks. You need leaked radio for a ROM based on one of the jellybean leaks.
As for flashing instructions you can follow the op as there will always be instructions posted, but personally I wipe data/factory reset, cache, dalvik, format/data, format/system and format/cache all x3. Yes it's excessive, but I've never had a problem.
Normally you will wipe then flash rom-->gapps-->any other tweaks (ie. Audio, GPS patch, etc)
All ROMs are easy to install. Just follow the instructions in the OP and you should be good to go

Awesome. So I create a backup (from what Ive read sounds like only Systems and Data). Its ok to have it on internal storage and compressed?
Then I use TWRP to wipe data, factory reset and clear cache? Is that correct?
And then I will move on to " dalvik, format/data, format/system and format/cache all x3"...not sure what this means yet but reading up on it. Are these all things I do through TWRP?

Backup with Titanium and restore w/ data for necessary apps. I do w/ data for things such as Apex launcher and other apps that have data I want to keep. If you do this then your icons for your launcher that was backed up will come back after the restore. Any widgets will need to be manually placed back on homescreens

Yeah not too smooth. I got caught up googling around for helpful links and reading on XDA that I ended up following a thread on how to flash, rather than realizing it was for a different device.
Thanks for the patience.
Just to double check...on Titanium Backup I want to choose Back Up all Apps + System Data....then post flash, I restore with the System Data...correct?
I searched quite a bit but was left unsatisfied with the answers provided.
1. How to fresh install roms (cleanrom in my case)? Just factory reset in recovery before flashing (TWRP 2.4)? Wipe Cache, dalvik before or after?
2. What's the proper order for wipe cache\dalvik\data? Is it before rom installation, after or both ?
Lets say im using stock rom and want to do a clean install. I just want what comes with clean rom. No leftovers from the old installation. What steps should i take?

I consider what I want and what is suggested as the proper install for the particular rom (see the op as roms vary).
You don't want anything left so I'd do spring cleaning. In twrp ( update your twrp to 2.4.1.0 ) if I wanted clean as you say I'd wipe cache, dalvik, data, and system (no formatting just wipe). Before you do this make sure you have one known good backup on your internal sdcard and on your external sdcard. You should also have a flashable zip on each. Insure you can see these files on both cards (with twrp) before you wipe. If you practice this method you will always have an out if there is a problem. If you don't then with what has been wiped you are assured a brick at sometime in the future. I do this before to clear my unit; when you are told to do some wipes afterwards this is to clear something in the rom you are flashing.
Sorry but I was required to say that as you never know who might see this in the future and not know to protect themselves.
Make sure you are unlocked. Install TWRP 2.4.1.0 over fast boot from a PC or too manager if you are already rooted.
You can install CROMI straight over stock with a dalvik cache and cache wipe but if you want a clean system just wipe data via the factory reset option inside TWRP (not the boot loader) and then flash the CROMI file. Recommend odex if you are just starting out.

That sucks. There's software out there that can probably help you recover what was on your card.
As for a clean install, you'll probably want to throw a ROM image/zip onto another SD (if you plan on recovering from your current one) and then get into recovery to flash it.
It's a pretty general set of instructions, but as sbdags said though, you may find better advice in the right forum.
What exactly does this do? Every time I'm flashing a new ROM and I wipe/fix permissons I seem to hang at the boot screen. Am I hurting myself not doing this?

You shouldn't have to fix permissions on a new ROM flash. In fact, running the fix permissions command is rarely needed. I would never make it a routine thing to do.

Some more info would be much appreciated here; I realize there is info out there but I'm still not 100% sure *what* I'm actually doing besides following instructions when doing wipes to flash anything. Not hijacking the thread but I'll rephrase the Q and hopefully someone can help clear things up:
When I read thru various guides for flashing various updates including ROMs, Gapps, kernels, system MODs etc, it seems that the order of the wipe and the extent of the wipe differ even between the same ROM (different model phone, ports, etc).
Is there a "standard" wipe procedure/ order of steps for;
(a) flashing a ROM update (assuming same kernel, and gapps flash needed ontop)
(b) flashing a new ROM (from a different build and/or kernel)
(c) flashing a system MOD (ex: crossbreeder)
(d) flashing a kernel (update or new)
I know there are those who feel that OCD urge to wipe wipe rinse repeat for every little thing but I'm hoping someone can clear us n00bs up on *why* we are doing what we are doing. The *essential* wipes and the order of each, and what files/partitions is that wipe effecting.
One more to expand on OP's question;
When then *should* we fix permissions?

There is no standard wiping procedure. At the bare minimum you should factory reset, wipe cache, and wipe dalvik cache for a ROM. In some instances a dirty flash may be recommended for an update, but not always. Others like to add steps to the reset, such as formatting system. I always clean flash for any rom by factory reset, wipe cache, wipe dalvik cache, format system, then flash rom. I usually flash a kernel without wiping anything.
Different developers have different opinions on what you should do and how efficiently it works. In my opinion, I think a lot of the multiple wiping procedures some developers recommend is unnecessary. However, if I'm running their ROM I will follow the instructions exactly so I can accurately report bugs to them if something comes up.
Fixing permissions is usually unnecessary, it has to do with rewriting app permissions to the kernel and will often fix issues involved with force closing. I really don't think it helps too much, but some devs like to recommend it. The reason it takes a long time to boot is because after you fix permissions, every app has to ask the kernel to run again. Which can take a while depending on how many you have installed.
