Switching ROMs in EXT4 - Epic 4G Q&A, Help & Troubleshooting

Once I have converted over to EXT4, can I flash any EXT4 friendly ROM directly? What CWM version do I need to use to flash it?
Sent from my Epic 4G using XDA App

Yes, you can flash any ext4 compatible rom.
If it has been updated to use an edify script, then it is compatible with 2.5.1.2 and 3.0.0.whatever.
If it still uses an old amend script, then it is only compatible with 2.5.1.2.

Yes, once you convert to ext4 that stays intact until you odin.

Thank you for your help

Sorry, even newer it seems.
Sorry guys, I'm even newer than airbag84 at this. By flashing you guys mean to put the zip file on the root of the sd-card, and run the .zip file from recovery mode, using either version of CWM? I'm already on a ext4 rom, no more final kernel or clearing data, etc, etc?

Yes flashing = installing zip in recovery mode.
When going from ROM to ROM, its a good idea to do a full wipe. However, unless you brick your phone and re-Odin, you will not need to worry about running one click ext4 again, just wipe and flash just like you would any other ROM.
Hope that answered your question.

& Ryno, how is it that the full wipe thingy works? Sorry for my newness(if that's a word)

do I wipe data or cache partition? or both? how many times?

Both. Wipe data, cache partition, and dalvik cache (under "advanced" in clockworkmod" 3 times to be safe. The reason for this is to ensure your not mixing files from two different roms, which could cause a ton of problems.
And don't sweat it, I was new at one point too. Hell, I am still learning lol.

[Q] Best Way to get Super Wiped?

I tried a ROM update today (Magnolia) and my phone is now seriously slow (including SpeedTest which shows about 50Kbps download speed). I attempted to reinstall the same ROM and to restore a Nandroid (neither of which has helped). I did every wipe present in CWM v2.5.1.2 (I know v3.x.x.x is not a good wiper) and in HBOOT, also all to no avail.
It is possible that the ROM is focused on carefully updating itself rather than completely overwriting.
Does anyone have a recommendation as to the best way to really ensure that no old runaway processes are surviving the flashes (ROM or Nandroid)? I am wondering if flashing another ROM would do it (it wouldn't try to update), but am very open to suggestions.
Thanks!
I had the same problem when I would install a rom with the CW 3.0.0.8 and it will just update the current rom, and not do a full wipe like I just to get before with the CW 2.x.x.x what I have done to get a clean install is this...
- I dont use the Rom Manager no more to update...
- Boot into Recovery and do the Following before you install a new Rom..
1-) Wipe Data/ Factory Reset
2-) Wipe Cache Partition
3-) Install the Rom .Zip with CW
Thats how I have done it before hope it helps...
Dont use rom manager to install go into recovery. Do a factory reset twice, then goto mounts and storage and format manually, data, cache, system, boot. Do that twice or more and youre super wiped as you put it. But as far as magnolia goes...did you make sure that you dl'd the flashover and not the whole rom?

Pete - Thanks. I never use RomManager to do ANYTHING (and remain surprised that people do). I do factory reset and wipe in CWM but never formatted system; which I just posted in the Magnolia forum as being what I thought is causing all the trouble. At least this lets me know how to manually do it. Thanks

Building on this- I do EVERYTHING from recovery. In addition to the steps listed I also go to "mounts and storage" and wipe /system, /data, /cache, and /boot. Eradicate!

[Q] Flashing from CM7 nightlies to a different ROM?

Hi everybody....Ive been flashing ROMs from ROM Manager and never had problems...until I tried to flash from CM7 nightlies #66 to a leaked G2 ROM][04/28/11] TMOUS G2 Gingerbread 2.13.531.5.
I did the usual wipe cache and dalvik and proceeded, it seemed like it was downloaded but got stuck on the reboot, it was stuck on the HTC logo for a long time. I thought I bricked it but managed to get it to work by taking the batterie out and going into recovery by clockworkmod.
Is there any special way to flash ROMs from the nightlies on a G2?
You said you wiped cache and dalvik, but did you wipe data too(factory reset)? Pretty sure you need to do that if coming from cm to the stock tmo leak. Could be wrong but sounds about right

that is right anytime change roms that are not linear to the same dev, it is best to wipe all, data/factory/cache then flash rom

Hmm, I checked everything that ROM Manager suggested, cache/ dalvik, the only thing I didnt check is to back up current ROM.
If you wanna wipe all that data/factory/cache do yo have to flash it manually?
Flashing other roms I think messed up my phone lol. I just stay with cm7 now lol
Nonsense!

even if you did say to wipe /system and /data in addition to /cache, CWM is notorious for not actually formatting the partition. go into the dev section and find SuperwipeG2 and if you are switching from aosp<->sense or, as earlier mentioned, from one dev's rom to another, run superwipe before doing so.

[Q] Weird bug while flashing ROM's

Having trouble flashing rom's
example:
after wiping data, cache, system etc., I go ahead and flash the rom and reboot. Phone sits at triangle boot screen for 10+ minutes with no activity. Have to do nand restore to make phone usable again.
Ive had this problem with all roms that require a SYSTEM wipe too. The issue is anytime I format system, it does something to phone that wont allow it to boot up again normally.
Any ideas why and what I can do to fix it?
Are you WIPING the system or FORMATTING the system? You've got to FORMAT over here, unlike just wiping on HTC devices. It should be under "mounts and storage" (or whatever it is), iirc.
Or head over to the thread for Calk's ROM and pick up his Format All zip file[/url].
sorry about my phrasing. I am FORMATTING the system through cwm mounts ans storage menu. Also I have tried that zip without success.
Whenever I go through the wiping/format process and load up a fresh rom, it never boots into it and just sits at triangle screen. To recover, I have to do a nand restore.
Really want to try the new roms coming out but im stuck w starburst
Which ROMs are you failing to flash correctly? Are you using official CWM that you boot to via ROM Manager or are you using a version packaged with the kernel?

Im using the one that comes with root. So Im guessing the one packed with the kernel.
Also this has been with the starburts and calks roms.
I have posted my question in their forums and they have said it can be related to a bad rom dl. So re dl again but I still experience the same problem

[Guide] CWM Touch JB Backup/ Restore and Flash new ROM

Thanks to Hobby31 (http://forum.xda-developers.com/member.php?u=2360932) for figuring this out. I have taken his post, and rewritten for ease of reading. Tested and working on (at least) 2 phones so far.
How to restore a Nandroid or flash new ROM with CWM Touch
In CWM Touch Recovery
1. Go to mounts and storage and unmount cache.
2. Make a nandroid. (Going back to mounts and storage, you will see data is mounted and will not unmount.)
3. Go to "advanced" and select reboot recovery.
4. Once phone reboots into recovery, go back to mounts and storage and see that data is unmounted. You may now wipe data, system, and cache.
5. You may now restore a nandroid or flash a new rom.
Recommendation : As noted below, proper wiping matters when switching between roms, particularly from ICS to JB. Use superwipe from Mike (android revolution HD) when moving between roms. http://api.viglink.com/api/click?fo...="0" alt="">&jsonp=vglnk_jsonp_13416929577832

EDIT 7-19-12 If you say "I've had no issues doing backups and restores with CWM," please ask yourself the following questions:
1. Are you using CWM Touch or non-touch? This is a Touch issue. If you are using the non-touch... you need not read further or report "I have no problems" because this is specifically related to Touch. (Please note I have not flashed the new 6.0 CWR Touch as some people are reporting problems with it also.)
2. Did you do multiple operations in the same recovery session? Meaning did you wipe data/factory reset, wipe cache, wipe delvik? Then did you try to flash a new ROM or restore a backup without restarting recovery? The reason this matters is because this issue of data not unmounting seems to happen in Touch CWM after a wipe is performed. You might be able to do one action per recovery session, but doing multiple actions that require data to be unmounted are what borks the operation and leaves some people hanging at the glowing X of "Oh crap I need to boot back into recovery."
Let me know if there are any problems, need for further clarification.
I flashed an older version of CWM (5.5.0.4) Non Touch version so I could flash JB but my SD card would not mount after I did a full wipe. Had to use the Toolkit to flash stock image. Do you know what would cause that to happen? People are saying to use the older version to flash JB and I want to try VanirBEAN ROM but don't want to run into the same SD mount issues.
I have not had any difficulty restoring cwm nandroid backups of other ROMs, or flashing other ROMs coming from V3. Have not had to resort to any of these steps. But I have seen a lot of threads about others having a lot of problems. Just curious if anyone has any theories about why this is?

After talking with others, I think my issue was after flashing the older CWM I did not reboot before moving forward with the wipe. Too chicken to try it again
I think it has to do with the coding in vicious and some of the initial releases of JB roms. Coupled with the data not unmounting at the proper time. A couple people also have mentioned that they didn't do as full of a wipe as is done with the super wipe script, hence why a lot of devs suggest using it to clean out old ics code.
Has nothing to do with Viscious. Same on JellyBelly 3.x Even when moving between JB roms, Data won't unmount when performing multiple operations.
I have flashed all three versions of Vicious' JB with CWM Touch and have not had a single problem. My process is as follows:
-Backup
-format /cache
-format /data
-format /system
-Wipe Dalvik cache
-Flash ROM
-Wipe Dalvik cache
-Reboot
-????????
-Profit
Team win recovery aka twrp. Everyone done says "use non touch recovery" it doesn't matter. Haven't had a single issue using twrp on this phone or any of my previous phones. It works great. Especially with super wipe scripts.

Bingo. That's what superwipe does.
Added link to Mike's superwipe.
Sorry for the dumb question, but ive done a search and found conflicting answers. When you wipe data and cache do you want them to be mounted or unmounted?

I have Touch CWM and I have no problems flashing back and forth between JB and ICS roms and nandroids.
You just have to flash a Super Wipe in between.
I just did this yesterday to test out my MHL adapter. Backed up my JB rom, super wiped, restored my ICS Liquid Rom, tested, super wiped, restored my JB rom.
I think super wipe is key in going between different rom builds. But I've had absolutely no problem using CWM at all. If Super wipe is the answer, then perhaps CWM's Factory Reset option isn't wiping as well as it should.
Flashing a SuperWipe is much easier then having to restart the phone a few times.
I think it may be related to Viscious old versions. Not Sure. Using Jelly Belly now. If you are not having problems, that's great. I used superwipe script. No problems. But, if people want the manual solution without getting errors, then at least we know the above method works. It might not be neccesary now with the newer releases, maybe data will unmount ok.
If anyone wants to test and see if they can restore old backups from ICS w/out doing the above steps (IE the rebooting) and report back, it'd be appreciated. I will be uber busy the next couple days or I'd take the time to backup to my computer before trying.
Would you mind sending me the super wipe script to flash? Or point me to the thread?

Are you using Touch Based CWMR? Or Standard.
I can confirm even with Jelly 3.6, that after I wipe data, cache, and delvik that the data will then remain mounted and not unmount unless I restart recovery.
This can/does cause problems and messes up operations when people are doing multiple actions in recovery at the same time. You might be able to do one action, such as making a backup just fine. But if you are using CWMR Touch, you might have issues with doing multiple operations in the same recovery session, like, backup, wiping, then restoring if the action you are doing requires data to unmount.
So, if you say "I have no problems..." please confirm that you are using touch recovery... not just standard.
CWM Touch was updated to 6.0.0.5 this week, is this issue still present? I haven't experienced any problems yet using CWM Touch, I'm just curious.
My steps are 1. Backup 2. Wipe data/factory reset 3. Wipe cache partition 4. Wipe Dalvik cache 5. Flash ROM 6. Flash GApps if needed 7. Reboot

Making an wipe script flashable zip

Hello there,
I was thinking to make a flashable CWM script that eliminates the necessary steps before changing a Rom. He script should have this content:
/format data
/format cache
/format system
/format Dalvik cache
Would it work? If yes has anyone such a similar script and share it please?
Thanks
First of all, wiping dalvik and system is redundant.
Wiping data wipes dalvik (/data/dalvik)
Also, when you flash a tom, it automatically wipes /system unless you're flashing an incremental update.
So why do you want this script when you have to push like 2 buttons anyway (factory reset/wipe data and cache)? The red be more trouble migrating to the flash able to wipe stuff than going to the wipe menu.

no. the rom you're flashing has to have the script to wipe system (most do, but there are some that do not)

If it doesn't wipe system to install the rom, then I don't know what you think it would be installing....I would question that 'dev ' that does that.

If the ROM doesn't wipe /system, then most likely you're flashing an incremental upgrade, or the dev doesn't know what in the world he's doing and you should probably steer clear of said ROM.
Also, AFAIK, all the gnex ROMs here at xda, rootzwiki, and cyanogenmod wipe /system.

I understand the knowledge shared here but better be safe and follow all four steps then be not sure? Or not?
Can someone help by providing such script please?
Search for the Android Revolution ROM in the dev section. IIRC they have some kind of script in the OP
Anyone can pass Wipe Script Flashable ZIP me to flash (for Baked ROM)?
Thanks!!
There's no need to wipe until after you're done
