Since I have seen alot of individuals within ROM threads stating things such as, "Your ROM bricked my phone." or "I can't get your new ROM to install." decided to make this guide. Hopefully it will solve this issue and help educate people.
What not flasing correctly can do:
1. Cause your phone not to boot
2. Cause Force closes and issues
3. POSSIBLY Brick your phone (though I have not seen an Eris Brick yet)
We must also remember that:
1. The devs of these ROMs are NOT responsible for any damage to your phone
2. The devs spend alot of time with testing to make sure the ROM works.
3. A ROM will NOT always flash over a previous ROM
OK.. So onto the main topic..
assuming you are rooted and using AMON's Recovery. I suggest AMON's because Clockwork has had recent issues. Big thanks to AMON for this!
How to install a ROM properly:
1. Boot into recovery ( with either reboot to recovery option or powerdown and then holding volume up and power )
2. Goto Backup/Restore and do a NAND Back-Up
3. Do a data/factory wipe ( NOTE: if the dev says you can flash over an old version you dont NEED to do this, but if you don't do this and the ROM is not booting then I suggest you restart this process [minus the back-up] and do a data/factory wipe)
4. Do a Dalvik Wipe... 3 times (ALWAYS ALWAYS ALWAYS do this)
5. Flash ROM
6. Reboot and Wait ( after a Dalvik wipe and flashing ROMs first boot can take 3+ minutes to load... BE PATIENT )
More to Come...
If you could, please explain what a Dalvik flash does. Thanks in adavnce, and thanks for this thread. I've never had any issues flashing, but it's nice to see someone explain the basics....

"Dalvik cache is a program cache area for the program Dalvik. Dalvik is a java based virtual machine that is the bases for running your programs (the ones that have the .apk extension). In order to make access times faster (because there's not JIT (just in time) compiler installed by default), the Dalvik-cache is the result of Dalvik doing a optimization of the running program." - Taken From Android forums
Basically it analyzes the phone before it boots. Then it sees what apps you have and will use and assigns cache to them. This way they will load quickly and properly.
When you flash a new ROM apps can change, or if you do a data/factory reset those apps are gone. SO wiping the Dalvik allows it to rebuild itself for what YOU are using.
This is also good to do after cleaning out or removing many unused apps from the phone. I usually do it once a week AT LEAST.
With the exception of a 2.1 ROM running apps2sd on an ext partition, is there really any point to wipe Dalvik if you have just done a wipe data/factory reset (which also wipes Dalvik cache)? And what exactly is the point of wiping Dalvik three times - why is once not enough? Is there something wrong with Amon Recovery which prevents a full Dalvik wipe unless you do it more than once?
It certainly doesn't hurt to wipe Dalvik after a wipe data/factory reset, but it should be already wiped.
I'm still fairly new, but I've flashed quite a bit. I didn't know to wipe dalvik x3. that's an interesting bit of info. Any reason why? Thanks

I believe the reason is that sometimes even after a wipe people have reported residual data in the cache, I personally don't do it three times but I do a wipe, dalvik, dalvik, wipe.
Its not going to hurt anything and it gives me piece of mind.

cool. Thanks for the good info.
x3? I do once before and once after. Frankly once before has been enough for me... though I suppose being safe has never hurt.
If the dalvik cache still won't clear after 3 times you can piss on your phone. That seems to really help.
in most cases once is enough but like I said, it's not likely to hurt anything to give it a couple of wipes to make sure all the junk data is cleared.
Let me put it this way...
I wont use a public toilet just by seeing it is clean... ill clean it like twice ...
This is why I dalvik 3 times lol

It would be interesting for someone like Amon to comment on the need to wipe data or recovery more than one time. In my opinion, once is enough. I'm 100% confident than wipes #2, #3, and so on are wiping blank space...

I personally and others have experienced residual data... so is three too much... maybe... but its safe... two might be a better choice... this guide was made to make sure you have no issues... therefore I said three times for safety... if you want to just do it once... be my guest

At the risk sounding like an idiot, I must ask this:
You mention wiping the Dalvik once a week. When you do this wipe, do you replace it (flash) something over it? Or can you simply wipe then reboot.

Yep, just wipe and boot. After wiping dalvik, it will redo your app tree or configuration if you will, just clears all the current info and rebuilds it fresh.
Great thread, people still need it I guess

I have tried to flash my nook several times. First with deeperblues honeycomb and then with cm7. On the honeycomb flash it just hangs on the android_ screen and with the CM7 it hangs on the cyanogen splash screen.
Have tried with different versions of CWR and different SD cards. have tried formatting boot and without for the Honeycomb. Always formatting cache, data and system for both cm7 and honeycomb.
Each time, i flash back to 1.0.1 stock, then root, then try to flash the mod again.
It always works returning to the stock 1.0.1 using the cwr complete restore found on the nook color portal. And the autonooter always works as well.
This is frustrating me as im not amble to install any cool mod on the nook. Does anyone have any ideas as to why my NC is resisting any change i make to it other than root stock 1.0.1?
It sounds like a symptom of not wiping data, but you said you're doing that...
Just to be clear, before flashing, you're doing "wipe data/factory reset", then "wipe cache", then "wipe dalvik cache"? Formatting /system shouldn't be necessary but I guess it wouldn't hurt.

I have tried the wife data/factory reset option once when trying to flash honey comb. Still gave me the same issue. All of the how to's i read had me formatting the data, cache and system, and depending on the how to sometimes the boot partition as well. Have been following those to the letters. This is the first time i have heard of wiping the dalvik cache, is that different than wiping cache under the mounts and storage?
Was there a color sticker on the box of your Nook?
Also, have you tried doing an SD only install rather than flashing the internal?

Not sure about the color sticker on the box when i bought it. It was right after it came out so going on a year ago. I have tried the SD only install, that works with honeycomb at least, thats the only one i have tried, all be it laggy because i only have a class 2 card at best.

I did some searching and i think what your eluding to is maybe my partition is the new style(although like i said i bought it within about a week or two of it originally being released)? would running the repartition in CWR make a difference do you think?
The option to wipe dalvik cache is under "advanced" in CWR. Try that in conjunction with a data and cache wipe.
As for the partitions, I don't think it should make a difference. It also sounds like you're on the old partitioning scheme which is the better one to have. You could try flashing the repartition/reformat zips just for the hell of it. Personally I went with the custom 2/4 setup.

Will try once with wiping the delvik cache, data, and cache. I wont wipe the system or the boot. If that doesnt work, il try the repartition and start from scratch. If anyone can think of anything else please let me know.
Hi
I just flashed my phone with coredroid 8. I wanted to get rid off all the aps and make it virtually new as I bought this from a previous owner and it had their data on it.
But all the apps remain? Why?

Did you just flashed the ROM on top of the other one or you've done a full format?
Hi I did wipe clean and cache in cwm. It installed fresh however all apps are there.
Shall I format my SD card and flash again?

Hi what ROM do you use? I am using coredroid 8 but waiting for 7.6..
Need to know how to do a clean install. Radio is flashed fine.
Can you please copy and paste instructions here thank you.
Sent from my HTC Desire HD
Did you factory reset/reset data, and system? Wiping your SD card won't get rid of apps.
1. format system
2. format data
3. format cache
4. wipe dalvik cache
5. wipe cache partition
6. wipe data/factory reset
7. DON'T REBOOT flash rom
8. reboot and wait (first boot may take long)
If you do it like this you will have a 100% clean system. After setup your Gmail account all your apps should get restored by Android Market (may take a couple of minutes). If you don't want your apps to be restored open the market go to "my apps" and cancel the download.

Okay great. The apps came back because of my gmail account.
Erm, can I format my SD card or will that mess up my rooting, clock work recovery and ROM manager etc?
There's alot of junk left from previous user. Id like to have a complete clean start.

Sure you can but make a backup of your card before you do it. Maybe you need your fotos, music aso.
There is no problem with root or recovery because its on the phone not on the card.

Hai all, I'm new to iconia. I've been flashing a custom ROM, a Taboonay ROM, great ROM.
I'm curious about get the original setup like a brand new iconia, without any trash folder after I restored my stock ROM. Tried with hitting the reset button, but it didn't work at all, still got the titanium backup folder and documents..is there anyway i could do to make it clean like i bought from the shop?
Thank you for your response..
hhmmmm
I may be missing a step here, but...
Boot into cwm
Clear user data, cache, dalvik, battery cache
Flash stock rom using cwm
Clear user data, cache, dalvik, battery cache
Someone please correct me if I am missing something here
Works for me. Have done so a few times.

There is a thread in the Dec section that talks about during entering recovery switching the orientation rocker.and also a thread of putting a blank file landed something then flashing that as well.both of these or one might be related to your issue.
Good luck.I just remember reading those threads.have not tried either as no need to.

Hmm, pretty sure the orientation rocker startup is just for clearing cache - I could be wrong. Took me like 20 times to get it to work, remember using it a few times when i thought I had bricked my a500

follow these steps and your device will be just like new ( no leftovers )
Especially step #5 where it formatted the boot, system, and data:
It's like you formatted the hard drive on your desktop before installing the OS
wiping the cache & factory reset is not enough !!

I think i'll try it, because only wipe & factory reset still keep all folder like gameloft, titanium, etc..even all downloaded files remain exsist...so it's not enough...
If you did Soft-Brick your new Nexus 7 2013 and you cannot access your Nexus 7 from your computer or a Factory Reset does not help please follow this guide. :crying:
(This is way different than the 0 Internal Storage bug. Go here: http://forum.xda-developers.com/showthread.php?t=2380913 )
Step 1: Download and install Wugs toolkit from here: http://www.wugfresh.com/nrt/
Step 2: Let it download the files it needs and choose what device your have EXACTLY what you have.
Step 3: Install the universal drivers by finding the Initial Setup part which is the big bar at the top. Go to the Step 2 tab and install the Universal Drivers and then let that install. It installs ADB so you can access ADB even in recovery if you could not before.
Step 4: Launch the Advanced Utilities in the bottom left and you will need a new ROM. Go here to get one: http://forum.xda-developers.com/forumdisplay.php?f=2411
gApps: http://goo.im/gapps
Step 5: Once you have those two things go to Flash Zips at the top right and tell it that the file is on the computer. Go to add files and add the ROM then GAPPS and enable to the left that it is a ROM but disable the nandroid backup because you really don't need it at the moment. Also have Wipe Dalvik, Cache, and Data on at the bottom.
Step 6: Confirm it and let it flash. Done! It will take about 5 minutes. Go eat or do something while waiting. It might take less but if you want to be on the safe side just let it run until your device powers on. :victory:

I never meant for it to be a "magical" fix. It is just a fix for a soft-bricked Nexus which had a rogue ROM and a Factory Reset would not fix nor was ADB working. Maybe someone has this happen and if you have a Backup from lets say Titanium Backup you kind of don't want to Format Data. So if you could just appreciate if I made a tutorial for the less fortunate in Android I am sorry. Skip the thread next time please

And here not to format data. Though wipe and format are not the same, the end result to the user is still that the data is gone. So I'm not sure whether you mean for the data gone or not.

1. Usually, the better option is to find the most similar ROM to the one that the data partition was populated with, so there will be a smaller likelihood of problems. For example, an older working nightly of the same ROM. Dirty flashing a random ROM is less likely to be problem-free.
2. Out of curiosity, why a toolkit, especially when flashing a ROM zip from recovery (not even ADB or fastboot) would work just as well?

Alright Formatting Data wipes the whole device usually. Wiping the data gets rid of the users apps. Lets say you have a backup in storage/emulated/legacy. It will still be there after you wipe the data.
1. Yes but that is the users choice. I couldn't find a definite stock ROM to the device so I will just let them pick.
2. If you want me too I could make a tutorial using ADB if you really want me too. This was just a 5 minute tutorial on a toolkit and I understand that most people here do not like toolkits but it is a really easy way. Just tell me if you do want me to add ADB tutorial as well and I will. :silly:

I don't think formatting data wipes the whole device...just the data partition. Same as wiping data. The kernel and ROM in the boot and system partitions respectively stay. Wiping data wipes all user data as well, not just apps. In either case, I don't think sdcard gets wiped.
Since I won't be using it, I personally don't mind what you do with the toolkit, but users need to be aware that it's not the most problem-free method.

Does it now...how odd. Has it always worked like that on every device? On my Galaxy Nexus, TWRP specifically ignores the sdcard mount point.
EDIT: okay, I think I understand the confusion. I meant that wiping data/factory resetting from recovery doesn't wipe sdcard. I know that doing so from Android does.
