I've been stuck in a weird place for some time with my phone. After I installed clockwork mod, backed up, installed some flavour of FroYo, and made the mistake of trying to flash back my old back up without properly wiping things have been getting weird. I can use ODIN to flash fresh ROMs, but I always get a bunch of FCs at startup, and most apps don't work. I tried to do all kinds of tricks to completely wipe the internal SD, but there is always some remnants of old fun hanging about causing cascading errors and FCs. No matter what I try to do, MyBackupPro and Rommanager is always present, but not working.
How I can completely rid myself of anything not stock ROM?
I've finally gotten back to root ADB, after a long and hard battle. I believe this may hold the key to salvation for my Vibrant.
Any and all suggestions are much appreciated!
Things I've already tried:
EUGENE373_SamsungS_Froyo_PDA -> Stock 2.1 T959UVJFD
EUGENE373_SamsungS_Froyo_PDA -> battery pull -> Stock 2.1 T959UVJFD
Stock 2.1 T959UVJFD -> EUGENE373_SamsungS_Froyo_PDA
Bionix1.9.zip - would not install due to some error I can't recall right now. Will update.
Factory wipe - from Settings menu
Wipe in Clockworkmod menu
Wipe all in adb shell
The weird *2767*3855#* factory wipe
UPDATE:
Strangest thing happened: I flashed an old ROM back onto the phone with Odin 1.52, then the Updated Stock 2.1 also via Odin the usual FC-ing was still there. Then I rebooted into recovery, reinstalled the Clockworkmod recovery menu, installed the root-update.zip in order to have root shell access. Then I pushed VibrantDeodexed1_2.zip and Vibrantfroyo_R3.zip on to the sd card. I tried to apply the VibrantDeodexed1_2.zip, but it aborted due to some catalog not present. However, I did notice that the installation erased /system and deleted some files, and I had the notion to try and install the VibrantFroyo_R3.zip. The installation succeeded, and Lo and Behold!
the phone has returned to the land of the living! Wohoo!!
I do not fully understand how this can be, but there is no Force Closing of programs any longer. What a relief!
Thanks to everybody who contributed ideas!
If you're having problems, back up whatever data you want to keep to your computer. Go download eugenes 2.2 that doesn't brick. Flash that, do a battery pull once it's done (don't reboot). Then go get a stock eclair file, flash that with odin and check repartition. This solved every problem I had from flashing way too many roms.
Yea, when in doubt I thank the deities for Eugene and flash his "Froyo that doesn't brick" followed by the stock JFD firmware.

You clicked the "repartition" option? That should format your internal sd...

Yeah, that's the weird part.. It doesn't really delete anything. Files are still there, and so are the un-wanted system files, too.
Does anyone know if I can manually partition the sdcard?
Had a similar issue, and couldn't fully erase my files. Figured out how to completely erase everything, before you proceed, backup your files and be ready to Odin. In rom manager, enable advanced mode in settings, then use the flash alternate recovery option. That set my current cwm version to 2.5.1.2, now when I reboot to cwm i have a menu that says something similar to "sd and storage" and within that menu are options to completely format all of the internal storage. Be careful in there, you can delete everything, incl the sd ext, but I think this is what you are looking for.
Edited - I rebooted and checked the menus, mounts and storage in cwm is what you are looking for after flashing the alternate recovery, I can confirm this removes remnants that an Odin repartition or factory format still leaves behind, let me reiterate, backup your personal files, cause this does remove everything
After formatting, Odin away

When I boot into recovery, I always have to reinstall packages to get to the CWM recovery menu. I tried to clear everything from the mounts and storage submenu; I cleared system, cache and data, then flashed stock eclair. STILL the same applications and files sit on the internal SD.
When performing the wiping, all looks normal. It does take a little time, and the system reports that all is going according to plan, yet no files are deleted.
What can possibly make the phone act this way? Are there no super secret samsung-technician codes that allow me to completely wipe clean the face of the sdcard?
When you get into the storage and mounts menu, I would format everything given what you're experiencing. Format boot, data, system, cache, and sdcard. Dont format the sd ext, thats the physical card. After formatting all of those your phone should be an odin ready blank slate, mine was. Hope this helps.

this has to be one of the most useful threads. just last night i was messing with rom manager and enabled advanced settings, BEEFORE reading this thread. I've done so much monkeying, but didn't keep a journal or log, so ive got **** from so many hacks and tweaks (mods and themes)...
thanks, im gonna wipe this ****er clean.
Good Info..but moved to Q&A

I was hoping that would help you friend, that process wiped mine clean of all remnants. Good luck in getting her back into a functional state.
After reading som more, contacting Samsung Service, I've decided to send the phone in for service. [sigh]
I've learnt a lot about ADB, pushing and pulling files, rooting, unrooting, swapping ROMS and whatnot. Still, the phone is stuck in that weird place where I cannot delete files.
Hopefully the service team can fix this poor, misguided phone
Hey guys,
Just installed my first rom and my head is spinning at the unanswered questions i have.
my first question is regarding clockworkmod
if i go into "apply update from .zip..." theres an option that says "apply /sdcard/update.zip". That option was there even before i loaded a custom rom. If i clicked on that when I have a custom rom running, what exactly does it do. My understanding is that "update.zip" is from the original rom. Is that correct?
Second question
What is the difference between doing a wipe data/factory reset from CWM when compared to doing it through the settings menu?
I never make a back up because I have no issues starting over but i just realized that some roms require you to install it with a "stock device." If a rom requires a stock start, does that mean you have to odin and wipe it to the stock rom before installing that specific rom?
If a rom doesn't require you to have the stock rom, does that mean you can just flash over custom rom after custom rom?
In those situations, do you move the rom.zip to the root folder THEN go into CWM and wipe dalvik THEN choose "install zip" or is it another order?
Under mounts and storage, what does "format/system" do? is that the same as "wipe data/factory reset"?
maybe i should just go back to iphone. this is just a cluster**** of info.
Update.zip is old stuff, as you suspected its to do with official updates. Cwm works across many devices that's why it's still there.
Your phone is divided into several partitions. They are prefixed with a / because the Linux convention treats partitions exactly the same as directories. Unless you have been living under a rock you probably know android is a fork of Linux.
/boot contains the Linux kernel
/recovery contains the recovery mode software, in your v case cwm.
/system holds the system apps and files.
/cache is similar to the swap file on a Windows pc or the /tmp directory on Linux. Dalvik cache is stored here as well although I'm not 100% site how that works. It's something to do with the java runtime.
/data is all your user settings and apps.
Factory reset wipes /data and /cache thus removing all installed apps and your account settings etc. A factory reset achieves the same thing regardless if you launch it in cwm or from the settings menu.
When changing roms you don't need to go back to stock first, it's just the way some devs have written their instructions. You should however always wipe /cache when changing roms. A full wipe is not usually required unless you are changing to a completely new base e.g. upgrading from an xxalf Rom to xxlfb you shouldn't need full wipe or going from one xxlfb Rom to another shouldn't need wipe. Changing from a Samsung based Rom to something like Cyanogenmod you should always full wipe.
Always wipe before flashing as some roms modify /data.

thank you for taking the time out to write that.
What is the difference between advanced restore and advanced back up against regular restore and back up (in CWM).
Also, which exactly do i have to wipe. Which cache? There are three different options i think.
Lastly, if i made a nandroid backup of the rooted stock rom in its stock form with no mods, do i still have to wipe the cache when i install a new rom?

Advanced backup and restore lets you choose which partitions to backup or restore, vs the standard option which backs up everything.
As I mentioned earlier you only need to wipe the cache. Dalvik cache is a sub directory of /cache so wiping /cache will wipe that also.
You should always wipe /cache when installing a new Rom. It doesn't affect anything from the user perspective except that first boot will be long while android rebuilds the cache. It probably isn't strictly necessary when moving to roms with the same base but can't hurt since it has no negative impact. Even factory updates wipe the cache automatically for you. Some custom roms do as well but better safe than sorry since most don't tell you either way in the description.

hi,
this ROM works very nice for me, thanks all the deveopers!
i have few questions:
(1) since this ROM has OTA updater (it seems, from the changelog), next time when the new version is realeased, can i just update the ROM via OTA updater?
(2) i dont really understand what “Wipe cache/dalvik” and “Wipe data / factory reset” really do. my guess is that “Wipe data / factory reset” repartitions the internal flash memory of the original memory, so we can use all the memory for our purpose. (not like original Nook Tablet, in which they dedicate only 1GB for personal usage)
if i understand all these correctly, this means next time if i flash the new ROM and want to keep the old data, i should not do "Wipe data / factory reset", but only need to do "Wipe cache/dalvik"? is this correct?
thanks so much,
Jun

Wipe data/factory reset is an option in CWM Recovery. Really all it does (from the screen messages) is format both /data and /cache.
Assuming you have CWM Recovery (though I imagine that there are similar entries in TWRP, I've just never used it), to wipe both of the caches you will first need to go to the entry "Wipe Cache Partition", which I believe is directly below Wipe Data/Factory Reset. Do that 3x (that's always been the recommendation, anyway) then go to Advanced and click on Wipe Dalvik Cache (again, 3x).
Again, assuming CWM Recovery, when you're in the recovery Vol Up/Down goes up and down in the list, the 'n' key is for Enter, and the Pwr button goes back.
I don't know about the OTA Updater. I always download and install ROMs (on both my phone and my NT) via Recovery.
Since this is a CM10 based rom you probably don't want to do the ota updater since that is a Cyanogenmod feature. This rom is optimized for the Nook from the CM10 Source I would presume. I personally tried the ota uldater since i get the notifications all the time but i get an error message something like "can't verify the source with a string of numbers". Stick to the recovery based flash installation.

I agree with liquidzoo that you should probably do the wipe cache, wipe dalvik cache and factory reset 3times seems like overkill but you can never be too safe. Also i use twrp recovery and click the system button and wipe system a few times as well.

I'm not picking on you personally, but deleting and/or wiping partitions (in the case of /system) or directories (dalvik-cache) three times as opposed to once is completely unnecessary. You'll gain nothing by running the command three times over running it once, assuming you received no errors the first time.
When wiping the dalvik cache, both CM recovery and TWRP perform an "rm -rf /data/dalvik-cache" command using the shell. It's not Windows, and is unlikely to fail when passed the "-f (force)" option along with the "-r (recursive)" option.
In the case of wiping the /system partition, again both CM and TWRP write out zeros to clear the data on the partition. I would be suprised if CWM acted differently from CM and TWRP when wiping dalvik-cache and /system.
The only reason I bothered to look into what these commands actually do is to prevent a user from thinking there's a corellation between a failure to wipe 3x versus a problem they're having. If a 3x wipe "fixes" something for you, whatever the problem was, it's very unlikely that the second or third wipe was what fixed it but instead it was more likely a result of a clean install of the ROM.

Have fun modding!
No worries, it's just something I've always done as it's been recommended to me in the past (there are some ROM developers that recommend 5x, actually). I'm not saying that 3x over 1x is any better, but I've never had issues. YMMV, but it doesn't take much more time and I like being thorough.

sorry, but can you confirm that when i upgrade to the new ROM (from the same author), it is really necessary to Wipe cache &Dalvik cache?
i am confused because somebody told me that i can just flash the ROM by installing the ZIP file (containing the ROM), and reboot the Nook without having to wipe or clean anything.

I don't know if I am doing it right or wrong but I have flashed numerous ROMs and lately have flashed every version of SGT7+CM10+Cherry Picks,By meghd00t. from 24/09 thru my current installation of 08/10 with only one glitch and that was when I flashed enhancements v2 on top of v1.
I have never had any other issues with the above mentioned ROMs except when I flashed 04/10 with enhancement v2. I didn't have the tablet option.
The way I do it is as follows:
1. format /system
2. format /data
3. Flash ROM
4. Flash CWM emmc
5. Flash GAPPs
6. Reset Factory/format data
7. Remove CWM SD card put in data SD Card with Flash Player (no longer avail on Google Play)
8. Boot from CWM menu
Takes awhile to boot this first time. When booted up I bypass the setup screens.
9. Manually set up wireless (need to access auth web site at work and need wireless to be working to accomplish that)
10. Browse to a web site and get redirected to auth page.
11. Auth
12. Set up Google account and other settings, especially under Security <Install from other locations>
13. Download apps I want from Google.
At this first boot SD card is not mounted.
14. Shut down and do a cold boot.
Now I can see SD Card.
15. Install Flash Player from External SD Card.
16. Install Crackle from Play Store.
Now I check Pandora for Audio, Crackle for Video, other apps I use, utilities, keyboards, launchers, games, etc.
So far since Version 24/09 everything has worked for me with the two exceptions above, tablet mode with 04/10 with enhancement v2 and when I flashed enhancement v2 over enhancement v1.
I am now running 08/10 and am very happy with the performance, battery drain is more than CM7 but that is to be expected from a fairly new ROM but not so bad that it is unacceptable, to me at least.
I have never had a black screen or arbitrary reboot (knock on wood). However I do turn my tablet off when I am finished using it, so don't know about deep sleep. I'm using OnDemand, and three launchers without one being the default....Apex, Nova and Trebucket.
All I can say is these developers really ROCK, way to go guys!

You don't need to re-flash CWM every time you flash a ROM. Also, it doesn't make sense to me why you would do a factory reset/format after flashing the new ROM, I would think it would be done prior to flashing the ROM but maybe it doesn't make a difference, I don't know.
I've got TWRP installed to the emmc so I just download the new ROM to the SD with GooManager, reboot into recovery, do a backup, factory reset, flash new ROM & GApps and reboot. Only takes a few minutes.

Tried it as you mentioned, doing a factory reset before flashing the ROM and got a black screen and wouldn't boot. May have been a fluke but the way I mentioned above gives me a good image and alway boots. Don't know why, but if it works for me, I will continue to do it this way as long as it works for me. I have flashed numerous other ROMs the same way with good results each time.

For an update, yes it is recommended to clear both caches. To be clear, this is only for an update. If it is a new ROM, or if the author recommends it, you should also wipe /data and /system first.
You can just flash without clearing them, but you might run into unexpected issues, so it's not recommended.

I get a black screen for a while on first boot too, but it only last a couple minutes at the most and if you shine a bright light at the screen you can see the CM logo spinning. Are you sure it was hung?

When you clear the Dalvik cache, it clears out data stored in your applications. When you turn on your Nook after clearing the Dalvik, the first thing it does is it rebuilds the Dalvik cache, that's why it seemed like it hung on startup. I believe the long black screen in the beginning is when it rebuilds Dalvik for core Android apps and then when it says "Optimizing Apps", that's for the rest of your applications. The more apps you have, the longer it will take to build the Dalvik. No need to freak out, just a little patience is all you need. Correct me if I'm wrong, however, as I'm still pretty much a noob at this... :laugh:

Well fhe screen was black, no light at all and I waited for over five minutes for the Flash Screen to come up and it never did. Yes I know when you are waiting time drags. But due to the ROMS always taking awhile to boot up the first time I actually pay attention to how long it takes. No more then 2 minutes in my experience. I had to hold the power button in for a long time until it finally booted in B&N Recovery. Used my sequence mentioned in earlier post to flash the ROM again and everything worked as it should, GREAT. The number of APPs shouldn't be an issue as these ROMS only have the very basic apps.
I have read this forum and see the various and asundry errors some are getting, so far I have never gotten a major error, except for when I forgot to do the Wipe Data/Factory Reset after flashing.
I also got the "No Tablet Mode Option" with 04/10 with enhancement v2.
But I consider these minor issues and currently am running 08/10 with no issues, works smoother then any version of Microsoft Windows I have dealt with.
These developers are exceptional.

oh, so you always reset factory every time you upgrade the ROM? that way will delete all the old data/apps you installed, so you need to install all the apps again?
this is my concern, because i dont want to reinstall apps, or lose my data. so i think i just need flash the new ROM, then Wipe cache/Dalvik cache, and hopefully all the old apps and data are still intact.
thanks.

i have some questions on the "Enhancements":
(1) the correct way to install them is to flash version 1 first, then immediately flash version 2 right after version 1 (without having to reboot first)?
(2) i am not sure what i will get with this "enhancements". they will make video/audio playing more smoothly? is the quality improvement really noticable? anything else, like they make the battery last longer, for example?
thanks,

If you're running 08/10, the enhancements are not needed. That's my understanding at least. I had problems with V2 so I decided to not install them while on 04/10.

If you flash enhancement v2 on top of version 1 you will have problems, UI will stop. If you only flash v2 you will not have the Tablet Mode Option. So my understanding is that you can use either v1 or v2 but not both.
ROM 08/10 does not need either enhancement as indicated by the developer. ROM 08/10 works great by itself is my experience.
If I'm installing a ROM, backup the existing ROM and wipe everything.
If I'm installing a .zip package like GApps or an enhancement, backup the existing ROM, wipe Data/Dalvik.
Folks, these are development ROMS. Thar be bugs in thet thar code. It's going to take you longer than the time you think you're going to save by doing a dirty flash, and then having to restore the thing to stock (worse case) only to start all over.
Don't ask how I know.

so it is possible to back up the existing data/apps, then restore them back after the new ROM is flashed? could you please confirm this?
if so, how & what is the right steps to do the backup? can we still use CWM, or use ROM Manager, or other tools?
thanks
I noticed that after wiping data & cache and installing a new rom using CWM recovery, my device still knows my name. I have a US SGP5 (YP-G70) and I'm running the latest BeanStalk ROM. Is there a user friendly way to COMPLETELY wipe the device of all user data prior to installing a new or updated ROM ?
Thanks in advance for any suggestions/replies.
Why does it matter if it still knows your name?
Inquiring minds want to know

Not sure that it does matter, but being a student and having the desire to learn about this stuff prompted me to ask the question. Also, I think it is counter intuitive that the device owners name and other user data (e.g. old alarm clock data) would still remain after instructing CWM to "wipe data".
The funny thing is that right after I posted this question, a newer release of BeanStalk came out, and I don't think my name was displayed upon initial boot after install, like it had been in previous versions of the ROM. I believe that data is still on the device, but just not shown.
So I think I figured out the answer...Wiping data/factory reset in CWM does NOT clear internal storage, and some user data is stored there.
So to rephrase the question, is there an easy way to clear internal storage? Is clearing internal storage an option in TWRP or PHILZ ?
In cwm, go to mounts and storage, and you can format everything from there
In TWRP, go to Wipe > Advanced Wipe, and select every everything
Hi, I'm not exactly new to XDA, however my Note is my first real Android phone. My question is this: If I want to make a backup of the entire phone, so that I can install a new ROM, then restore the phone to exactly the way it was before I installed said ROM, what do I need to select to back up in TWRP? I'm wanting to play with the Lolipop build for i717. I already have a good EFS backup stored separately just in case, so I need to select System, Data, and Boot, and this will save the kernel and the ROM contents, correct? ...and when I restore this backup it will be just like I left it, right?
Also, what do I need to select to Wipe to perform a 'Full Wipe' as is recommended before install?
Thanks for your time.

Use gimmeitorilltell's version of twrp as some specifics have not made it to official version. I've had great results using 2.8.0.0 though I believe some newer versions are working now as well. I backup android secure as well. Not sure if this is necessary, it was the default setting. Wipe is generally accepted as factory reset usually followed by going to advanced wipe and checking cache, and dalvik cache and wiping these again. Then install your new rom zip, gapps zip if required, wipe cache and dalvik cache and reboot. First boot will take a long time. Possibly as long as 5 minutes or more. Once booted let rom settle for at least 10 minutes before adjusting any settings. Good luck.
Edit: Your backed up rom system will restore everything back to the way it was if you desire to go back (installed apps and settings as well).
