Hi all,
Sorry I cannot post in ARHD thread due to insufficient post count...so here are my newbie questions:
- I had ARHD 12 installed, now I want to update to 12.1. I know you can flash over 12 without wiping data but the question is do I have to wipe cache in TWRP before flashing 12.1 over 12?
- on ARHD blog, the author said "It is highly recommended that you back up your SD card content to your PC before flashing this ROM. When you are done flashing the ROM, remove the content of SD card and copy back all files from PC". Does it mean I should connect phone to laptop, copy everything inside, flash the ROM, then delete everything? And why is it necessary?
Apologies for bad English.
Erase cache if you want - it's not a requirement. Although I usually do it anyway..
Copying files to your PC thing your talking about was probably from the ROM moving from 4.1.2 to 4.2.2. Nothing for you to worry about since you're already on 4.2.2.
Just flash it..

thanks for your answer. I would probably wipe cache and dalvik cache just incase. However would I lose anything by wiping these? phone settings, accounts, app settings...?

You wouldn't lose anything of importance - just your caches. They will re-appear on reboot.
i flashed 12.1 on 12 and everything is great, i did't wipe cache or anything else. U can backup your files just in case

So every single rom for any phone I've seen says to clear the dalvik and the cache (or maybe its just the "dalvik cache") but when I went from stock to Thriller, I forgot to, and nothing went wrong. In fact, all my settings and apps were all intact from the previous stock rom.
I've considered that the only other phone I'd done any flashing on was a backflip, without Apps2SD and maybe that's why all my apps and settings were intact, so that still leaves me with the question: why clear it?
This may be a noob-ish question, and I apologize. Thanks for any help!

If there are any compatibility issues between the apk dalvik cache of your previous rom and the apks on the new rom wiping dalvik clears the previous apks stored dalvik cache. In most cases you can flash without a problem. But I recommend wiping between rom flashes just to eliminate any potential problems. Flashing something like Thriller over the stock rom you can probably get away with not wiping anything since all the apks are essentially the same. Flashing kernels you don't need to wipe anything. When flashing a rom with a completely different firmware I recommend a full data wipe. Restoring recovery backups such as nandroid require no wiping at all.
Also, wiping dalvik shouldn't affect any of your settings.

When switching ROM with different base apps, it is generally better to wipe caches than to get stuck in a boot loop, or having your apps and launcher FC on you. You never lose anything as the cache rebuilds itself on the next reboot, except maybe a few minutes

If you followed the instructions you did a full data wipe. When you do this the dalvik gets wiped as well. To just wipe dalvik look under the Advanced menu in cwm recovery.

clearing cache
i am using a nand rom in my HD2, and i also want to install another rom via SD in Magldr, but because of kernel issues i cannot load the Rom from SD unless i use the kernal i am advised to use. I am instructed to clear the dalvik and cache, but does this mean that i would lose anything from my current NAND rom? I still want to be able to use that of coarse so i just want to make sure there are no major risks when clearing cache.

Clearing dalvik and cache wont make you lose anything, used to do it with my shift because I'd flash about 10 zips a day sometimes...
Also when it comes to flashing any ROM I format system data cache wipe dalvik cache and do a factory reset just to be sure nothing from a previous ROM is left over also wipe my SD ext partition when running an a2sd ROM, my question is can I safely manually format the emmc partition of the thrill from the mounts and storage option of cwm

quick question, if you do a factory reset with odin and start from scratch, should you delete everything that is on your internal SD? Would that be a full complete wipe?
That is a FULL wipe but thats not what im talking about. Just the internal phone stuff.
what is formatted when you click to format /boot? for some reason I always thought that formatted the boot loader so I dared not touch that, but now I'm realizing how stupid it would be to even put that option there and how many more phones would have been bricked at this point. anyway when I install a new rom I pretty much wipe everything (including dalvik) except for /boot and /emmc ( I even formated the external recently but moved back images, efs backup, and avatar), then mount /sdcard, insert rom then flash, fix permissions.
formats the boot animation?
or after the VIBRANT logo
it's a ritual for me whenever i install a new rom to go through this installation method. I also notice that i tend to experience far less "bugs" then others.

Just being curious because some say it isn't cleared in the Factory Reset. Some ROM and kernel devs do suggest clearing Dalvik Cache after doing a Factory Reset because it prevents some apps giving FCs after flashing a new ROM.
Side note: I wipe dalvik about once every two weeks whether I am flashing or not. Helps with cleaning up corpses and getting better RAM usage. Thanks for the info Alan.
extra post :/
Nice find!
..now bend over.
One question Alan.
Can I Odin to stock from ICS passion just like we go from gingerbread or froyo from? Or is there a special way to get back to stock jfd? I want to try out jcc from but I don't know if I could just Odin to stock from passion. Thanks

What you using to reinstall apps and/or app data? Everytime I install a new ROM, I lose all my data connected to an app. For example, I play Drag Racing and you have to create a new login name everytime I install a new ROM. I would like to at least save the data related to that app.

Hi guys,
I believe this question has been asked multiple times, and i myself tried searching for answers from many various source to clarify my doubts, only to get more confused due to conflicting information.
Let's say now i am on a custom ROM. Before flashing the custom ROM, i made a backup of my stock touchwiz rom using cwm. However i want to revert back to the exact same state before flashing the custom ROM. What are the steps i need to do to restore the backup file?
1) Some sources mentioned just booting into cwm recovery, selecting "backup and restore" option, select "restore" and choosing the desired backup file will allow the phone to restore to the state prior to flashing.
2) Some other sources mentioned needing to wipe cache/wipe delvik cache/format system/format cache etc. first before i can restore the backup file.
So which is it?
Thank you!
Personally, I always choose option 2 if going to another rom. If restoring an earlier backup within the same rom i use option 1.
Don't know excact what the right thing to do is, but it never hurt to wipe cache / dalvik cache / system because you have it all backed up anyway. At least if you backup regulary. I back up regulary and delete the backups i don't want.

Thanks for the tip!
Is wiping cache/delvik cache sufficient in most cases?
Cos i saw a youtube video, where the guy did not wipe cache/delvik cache. instead, he formatted cache, data and system.

Wipe /
If problems format .

Any other things i should look out for or preventive measures i should take for restoring backup from cwm?
i have been reading of cases where restoration through cwm fails and they have to go through the whole process of re-rooting and flashing before being able to restore it
there is no need for wiping, the recovery does it on its own prior to restoring.
got stuck

When applying an update to a ROM, is a data wipe always required, or can I simply flash boot.img and the .zip over top of the existing installation?
More specific to my situation, I'm using Albinoman's CM11 ROM; if anyone has flashed the December 10 update without wiping data, did it fix the black browser issue or would I need to do a wipe? I'd post this on the ROM's thread, but I don't have ten posts yet.
EDIT: Wiped only Dalvik and flashed the update, works smoothly and the black browser bug is fixed.

I have found clean wipes the best but use the recovery option to reload certain data etc or back up apps and reinstall clean.
Basically, i back up contacts, calendars, sms etc anyway these days. Makes for an easy transfer of data when needed.

If you are updating the same ROM... Usually you don't need to wipe... Anything more than dalvik cache and cache
However... EVERYONE will ask you and then suggest a full wipe if you have any issues...

Hi all. I was able to flash a custom rom to my htc one m7 a long time ago.
I am currently using ARHD 91.0 and I am planning to try the new one 93.0
My recovery is TWRP.
I have a few questions and I hope you can help a newbie here.
1. What are the steps I need to follow in changing my previous ROM to a new one?
2. Will I be able to restore all my data (pics, contacts, apps, etc)? If yes, how and what do I need to do?
Thank you in advance!

1. Best thing to do is a clean flash. That means you need to wipe everything except internal storage from TWRP, and then flash ARHD 93.0.zip. You can also do a dirty flash - wipe cache and dalvik cache only in recovery and flash ARHD 93.0.zip, but that could cause various issues.
2. Save your contacts to google account, and you will have them no matter what you do with your phone. Your pics will be saved on your internal memory because you don't need to wipe internal memory. As for apps and data, that will be erased with clean flash for sure. I don't know about dirty flash because I always do a clean flash, but there is Titanium backup app in playstore that allows you to save your app data and transfer it onto a new ROM.
Wow, this must be the longest post I ever made [emoji4]
