How to PROPERLY Flash a ROM

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.

[SOLVED] HELP!!! Having a problem with my A500 and I may be screwed, PLEASE help....

Ok, so here's the back story as best as I can manage. I recently (like Monday) flashed a new version of Civato's Flexstriker to my A500. The flash went fine and my tab was working great. Last night out of the blue, the internet browser started acting up, locking up, and even rebooting the tablet. I have it overclocked to 1680 using smartassv2 governor. Anyway, I first thought it was because maybe it was getting too hot, so I underclocked it to something like 600MHz to let it cool, but no luck. So then I thought maybe it was because something was wrong with the ROM. I decided to nandroid backup, and re-install the ROM. This is where the fun starts. After attempting a complete wipe, I re-flashed and got stuck in a boot loop. Re-wiped, installed a completely different ROM, boot loop. So I started digging into the wipe and noticed that I was getting a formatting /data error and that the entire /data/app folder is read only.
SO now I'm thinking maybe there is a conflict between my ROMs and the /data/app folder that won't let it boot. I tried mounting the /data/app in adb and it won't let me remove anything because it says it's read only.
How do I clean this thing off completely and start over? I'm stuck with a tablet that doesn't work and that is not acceptable. (PS- I know it's all probably my fault, so I don't need a lecture. I am a complete newb on android/linux.)

Did you Wipe Data (Wipe Menu) or Format Data (Mounts Menu) in CWM?

yes. When I do the wipe data I get a format error. "Error removing...." so I checked the status of the /data/app folder and it's all read only. I tried deleting the files in adb using the rm -r command, but I still get the read only file system.
How do I change the file system to read/write?

This is also new, When I do :su in adb, I get a segmentation fault. what's going on?

Try to do format Data from Mount Menu. That Segmentation Fault I've received when the device was not correctly rooted. Maybe try flashing another kernel.

Still get the error formatting data from that menu.
I've flashed an older ROM, and still get the same thing.
I'll try locating a kernel to flash. So far, I'm stuck with a dead tablet. Anyone got any ideas?

I have several nandroids. the big problem is that I can't wipe the data directory because it's telling me it's a read only file system. And I can't change the file system because I'm not sure how to, and the SU comes back with a segmentation fault.

are you using cwm? if so what version?

If you are using Thor's CWM. And his recovery only;
Here are the steps to completely wipe all internal data. And give it a clean internal system (according to Thor)
Note: Optional Formatting.
If you really want to remove EVERYTHING in Internal Memory, at this point, go to Backup and Restore. Select "Toggle backup and restore of internal storage (/data/media). Enable this setting by selecting it. By default, it is disabled. Then proceed to the formatting steps. This will format the Entire Internal Memory when you proceed.
Note, this will format EVERYTHING in internal memory (not ext sd card)
Select Go Back, Goto Mounts and Storage
1. Format System
2. Format Cache
3. Format Dalvik
4. Format Flexrom
just let it format, and hopefully it will take care of the corrupted data
Then just install the fresh rom.
After you reboot, I believe it resets back to the defaults.
it will wipe your backups tho but that dosent matter if they arent working
im not an expert just passing along info that was given to me

Really, I am glad you got it running, and glad me and Dr Mcknight pitched in to help. He'll be an OC monster before too long
For all you users wanting to overclock. Never run at the max OC speeds. Usually they are unstable.
Yeah, i run at 1600, and I'm stable, but I am just lucky. But I don;t run it all the time. Typically, 1504 is fine.
Anything above 1600, is purely for benchmarks. And if you use it normally, at that speed, you may have reboots, freezes, corrupt data.
I'm lucky as I only had 1 reboot at 1686. Or was it 1748???? I forget.
So people, keep it at a normal level.

CPU'S and overclocking
Computer processors due to the way they are assembled. all have dead transistors.. Some call them simi conductors.. . With this being said .. not all of them can run at the same clock speeds.. In the far past when cpu's were made. they would test them to see the max perfectly stable speed to run at.. stamp them and sell at that level.. Power users and main boards started hitting the market allow you to change voltage and clock speeds . This caused a onslot of people over clocking.. That is what lead to LOCKED MULTIPLIERS ON Boxed cpu's.
Anyway what this all means is ONE Device spun on the same die . might run much faster then the one next to it . OP It does sound like you have taken life of your device . I DO Hope you did not cause to much heat on the embedded ram and rom chips. if so you will always have a unstable to end of life device
Tis the reason to never BUY A USED Gaming computer.. YOU KNOW it was clocked far to high way to many times..
glad you have it fixed and was nothing but corrupt data..

I'm an at home overclocker. So I guess I'm aware of the risks involved. And like I said, I normally don't OC this tablet for any kind of time. I just managed to forget about it this time. It didn't ever get hot to the touch, not even really warm, and I know the aluminum case is a link in the cooling chain on this device. So I'm pretty confident it wasn't baked too bad. BUT, you're right it still has the risk there. Hey if it becomes too unstable, I'll pass it down to the kids and get a new one.....

My Wiping Problems

Gentlemen,
I am having great difficult when I wipe prior to installing a new ROM. I obviously am doing to much and on both occasions that I have done this on my N7 have lost everything including my backups and operating system. I am left with just TWRP which worked great for me on my KF so I am not blaming it.
Would someone please be kind enough to tell me exactly which areas to wipe because I like to experiment with different ROMs but can't stand the stress involved of wiping out the complete device again. I am 70 years old and my heart can't take it!
Thanks in advance.

wipe data, factory reset. thats all. dont wipe anything on the sd. you only need to wipe data when flashing 2 different roms, not when updating your current rom.
damn, youre older than me. and i though that i was the old man here. guess not :silly:

The Most Clean Installation Possible.

Hi guys,
"Do I need to make a full wipe?", I see this question asked over and over on development thread. And the developers patiently answer all the time. Well you can stop asking, here is the answer.
There is a lot of reason why you should do a full wipe.
1-) It prevents FC's, bootloops, gives better battery life and reduce other unexpected problems.
2-) By trying to save a little time you might end up with problems, loose a lot of time try to fix them, and finally making a wipe anyway to solve your problems.
3-) Some people just flash over their old ROM and then complain that the new ROM is buggy or Android plainly sucks. I don't think it's fair to blame hard working people(who gives you FREE products) for your own lazyness.
So why not do it right from the begining and save some time to everybody. Here is the procedure that I use(Thanks to Memnoc and DarkAdrien.) and is the most clean installation possible.
Memnoc and DarkAdrien's original post was created for battery optimization, I only re-wrote the steps that involve flashing a new ROM.
This will work with every Rom but some ROM's might ask for extra steps (fix permission, etc..), read instructions first.
1- Make backup of your current ROM. (no need to do this everytime, I keep one backup of my favorite ROM)
2- In recovery go to "mount & format" and format system.
3- Format data.
4- Format cache.
5- Go to Main menu and do "Wipe data/ Restore"
6- Wipe cache partition.
7- Go to Advance and wipe calvik cache.
8- Flash your new ROM ONLY. (IMPORTANT: Wait after #10 before flashing anything else)
9- Reboot
10- (This step might not work between ICS/JB or between AOKP/AOSP/Samsung)
Go back to recovery and in Backup choose "Advance restore" and then choose "restore Data". -Reboot again
(if you have problem with some apps, you might want to uninstall them before the backup and reinstall them the normal way after #10, or you can use Titanium Backup to test if they work well in the new ROM)
# 2-3-4 are not doing the same thing as #6, Read original post bellow for explanation.
This whole process from 1 to 10 should take you 15 minutes. From 2 to 7 should take less than 1 minute.
Your phone will have a very clean ROM and all your apps, contacts, SMS, games, etc... will be exactly like they were before.
I've flashed over 50 roms using this procedure and it always work fine.

Then, by your own admission it is not always necessary. "better" ≠ "necessary"
If posters were clear that it is only recommended, not necessary, then no one would need to ask the question in the first place.
I've seen posts telling people to do a wipe when upgrading from official stock to another official stock. There is absolutely no need for that except in the rarest of circumstances.

full wipe is only required if there are major changes in the new rom to be flashed or the user is facing any trouble in his previous roms. Unless otherwise its a waste of time.

That list is a little excessive and needs to be tuned down. When you flash a rom it already formats everything except for "system"

Question.
I've been using LI5 for quite sometime without any problems, and a couple of days ago suddenly the phone started showing signs of sluggishness.
Even moving between the screens of Apex launcher seemed to be quite jerky. I tried uninstalling some apps etc (thinking they might have caused some memory leak or something), to no avail.
Just wanted to ask, will a full wipe and reinstall solve this problem? I'm planning to restore all my apps back.

I upgraded from stock ICS to stock JB, then through three more JB revisions.
I have yet to perform a wipe and everything is running great!

I have a 16GB phone and an 8GB card and, as of yesterday, they were full to the brim.
So- yes! People can have that much data.

Just one question................. Do I need to do a full wipe?
I'm sorry I just had to, but pretty much the rule is if the Android version is the same a full wipe is not needed, if it's an upgrade to the same android version ex 4.0.1 to 4.0.2 there is a chance you will need a full wipe, if the android version completly different ex 2.3.6 to 4.0.1 or 4.0.4 to 4.1.1 there is a good chance you will need a full wipe.
The exception is stock ROMs are usually designed as no wipe, therefore they have been designed so you shouldn't need a full wipe, but if there are any problems, like lag, or bootloops you should wipe, but it is not always needed.

Aughhhhh.
I've been quiet for a while and nice and peaceful.

every time i flashing a rom it going to be too laggy even after a full wipe !
even after changing the recovery the proplem not resolved !!

No solutions. All of us have this lag problem. Maybe it has something to do with our device from production.

Try wiping the whole device 3-4 times without -rf option enabled. It works. If it isn't working the use dreamstar's recovery and wipe the device

I m sorry I mean TWRP recovery and yes after going to advanced wipe I wiped everything excluding external sd card and flashed stock rom
Tried this many times but getting huge lags
Any suggestions????

You have to format data buddy. Instead of going to advanced wipe choose "wipe data"
Then flash Stock and then you can flash any rom afterwards. No lags guaranteed

There are only three options in twrp i.e. advanced wipe, format data and swipe to factory reset
Which one to choose

My mistake I meant format data there. Choose format data. It'll take a while but does the job

Use 3.0.1 from dreamstar..
And format data for 2-3 times and format system for 20+ times???.. keep a stopwatch and measure the time it takes to finish one wipe of system. once all the **** is removed it should be like 10mins some said that it goes like 14mins.. easiest way is wipe for more than 20 times and reflash ROM download A1 SD bench app. Do a benchmark of internal storage. If Write speed is 20MB/s or more then your problem is fixed if not go back to wiping ???

One of the easiest solution
Hello Everyone,
As all of us (G360H users) know, no matter what we do, lagness comes back after few days of smoothness. I am going to share what I do as a fix.
After flashing any ROM cleanly, lagness bothers after few days. So what to do?
>After you feel your phone is lagging, restart your phone to Recovery (TWRP 3.0.0 and above)
>Backup your system only (to internal storage or SD card doesn't matter, it's normally 600 to 700 MB)
>After Backup is completed, go to wipe section and then advanced wipe then wipe only system (at least 4 times without -rf option enabled, wiping takes some time)
>After wiping system few times, restore the system Backup from 2nd step, once completed restart your phone to system.
>Smoothness can be felt again but it's gonna come back again after few days (normally in around 15 days) REPEAT above steps again.
There's nothing new but this saves time in backing up and wiping up everything or the hassle of setting up a newly installed ROM. All your installed apps and data will stay safe and as they were.
Regards,
S

Well you just have to do that for a little longer . When we use a storage we write and delete data continuously.. So our eMMC acts like a SSD when we write data they store in blocks and when we delete them usually the indexes are deleted ad data remains. so when we write something again those data in blocks are replaced by new data. So when lot of I/O precesses are going on it eventually remains filled blocks and they acts like fragments in HHDs, o remove them we need the process called trimming. Due to our eMMC's bug that wouldn't finish completely. So we have to wipe the storage manually until all blocks are completely wiped out and clean. Unless R/W speed will get low like 8mbps and that causes lags. Be patient and wipe until it's all gone
