[Q] Wipe help needed. - Galaxy Y GT-S5360 and Duos 6102 Q&A, Help & Troubl

Is it necessary to wipe cache and data after flashing a Custom ROM?

well if the developer of the rom said so,
then do it,
since sometimes it causes bootloops if you dont,
in short,
just follow the instructions

Yes, as some system apps contain data and cache which would not link to the newly signed system apps. This may lead to several force closes obviously, and as deathnotice01 said, bootloops might be encountered too. That's why this step is always there in the installation of custom roms.
Code:
System.out.println("Sent from my SGY");

In short Yes... Its Good to do so...
Peace
Hit Thanks & It will Disappear

Help with Cyanogensmod 2.3.5 nightly

I have cyanogen mod 7.1.0 RC 1-vision installed on G2 already. Can somebody explain to me how I get to v 2.3.5? I know it has something to do with nightly builds and xboarder56. Im just a little confused on how and what order to flash things. Do I have to install every Nightly update or will the newest one be fine? And exactly what it xboarder56? Is that a modification of Cyanogensmod?
Thanks Sean.....
just install the newest nightly and youll have 2.3.5
xboarder56 is a guy that made a thread on how to install the stock launcher over the ADWlauncher
but you can alternately download a gingerbread launcher from the market and install it
Wipe, and flash the newest nightly just how you flashed RC1
Sent from my T-mobile G2 using Tapatalk
download the latest nightly, put on your SDcard
1) enter recovery (power button -> reboot -> 'recovery')
2) 'backup and restore' -> backup current ROM
3) wipe cache, advanced -> wipe dalvik cache
4) 'Install zip from SDcard' -> Flash nightly.zip
5) reboot
6) fix permissions (ROM manager -> 'fix permissions'
7) reboot again
xboarder56 is a dev on here. he makes several different mods for CM7. The main one that people use is to put the stock GB launcher on CM7. CM7 by default has ADW launcher, but some prefer the stock one. Xboarder56 isn't the only one that has a stock launcher.zip available.
If you want the stock launcher, check the post in my sig. follow the directions carefully if you intend to re-flash nightlies and want to keep your screen placement.
Do I have to download each nightly build? Or can I skip builds from time to time? Are these beta builds? and if so any idea on a final version?
Thanks... Sean...

You can download and install every nightly. But you dont HAVE to. There is a group that only flashes one every few weeks. Either way you will be fine but if you want to be on the cutting edge of new features i would recommend installing it every day. For our phone specifically they come out between 115 am and 130 am. Like said above, wipe cache wipe dalvik install nightly fix permissions reboot with each nightly

Dalvik cache is under advanced. I believe if you're not running Apps2SD you can go without it.

Apps2SD has nothing to do with the Dalvik cache. Wipe it regardless of whether or not you use Apps2SD (which is unneeded unless ur still on a G1).

They are effectively beta builds. They're not official and not necessarily meant for the general flashing community, as they often contain bugs and untested changes.

like I said above, its under advanced -> wipe dalvik cache.
It has nothing to do with Apps2SD. On a related note, there's no need to run Apps2SD unless you have several gigantic games or something filling up internal memory. You should have more than enough internal memory to keep all apps on the phone itself.
When I wipe my Dalvik Cache, CWM says it cannot find the drive/partition for it. Its never caused a problem for me. I assumed it was due to sdcard partitions, which I used to use for Swap and Apps2SD only. Is it an internal memory partition for performance related caching? If so somethings messed up with my partitions.

What exactly is it saying? usually it will throw an error about SD-EXT. disregard the error.
For me when I flash new ROMs I use Superwipe+ to do all my wiping in one step. Its quick and effective.
Check it out:
http://forum.xda-developers.com/showthread.php?t=1044992
Each and every morning, I make it my habit to launch Rom Manager (paid version), and select 'Check for updateds'. After it tells me there's an update available, I approve it and select to download (via wifi) gapps. Once it done downloading it then prompts me to choose wipe data & cashed, backup existing rom, or wipe dalvik cashe. I always select wipe Dalvik cashe, then I approve it to power off.
Bamb! easy sneesy .. My nightly rom gets updated!

I had the same question as the OP. I've been running CM v.7.1 RC1 for a while now and I love it. But I would like to check out the nightlies. Just so I am clear, to go from my current ROM to the latest nightly, I only need to to wipe cache and dalvik cache - and that's it? Somehow I thought the process was more difficult. I thought I'd have to restore my apps with TB and reconfigure all my settings...
And one last quick question. I've never needed to run 'fix permissions.' The sole FC I get is with LauncherPro, but only when I reboot. It doesn't bother me, and it seems like I've read about users who have problems after running the 'fix permissions' in RM. Can anyone elaborate on why that might be?
Thanks so much, guys.

upgrading from an older version of CM7 to a Nightly you don't have to wipe data. Just cache/dalvik and flash the nightly.

Fixing permissions is just a good rule of thumb to follow after flashing a new ROM so all your apps are setup properly. I haven't heard of Fix Permissions breaking anything.

[Q] Changing kernel after rom installation

Hello, although I've installed some rom's till now i'm still not sure:
I've installed Dorimanx latest rom (3.0.6) with his kernel, and I really liked it. But for some reason got a wifi Error, seen on forum it's a knows issue and that changing kernel might solve the problem.
downloaded hierOS kernel and now i'd like to install it. could I install it from cwm without reinstalling my rom? according to some threads it's possible but it just doesn't make any sense to me because it's on a lower layer.. thanks
please?
no one knows? or maybe i got it all wrong?
Just follow the instructions in the kernel thread. You may have to replace the initrd.gz file but there is no need to fresh install.

Sure, read it. but it won't guide for installing after rom is already running, but only for normal mode. And I'd like to go to cwm and run zip of the new kernel, [again, rom is already installed, not coz im lazy to reinstall rom, mostly out of curiocity]. thanks again
HierOS kernel is supposed to be for SENSE builds, so I don´t recommend using it with CM build. There are better options. Tytung, older DM kernels, new 2.6.35 bases etc. You just download zip, copy initrd.gz of your ROM if needed and flash via recovery as ROM. It won´t overwrite your data. You should wipe cache and dalvik too

Thanks, I'll go on tytung. according to his instructions I should just delete initrd.gz b4 installing. and I will also wipe cache and Dalvik. But shall I "format system" as i saw on other thread? or wipe data?

Just wiping cache and Dalvik cache will suffice, unless you need to wipe your current rom....Wiping system or data clears all files from those partitions, resulting in a loss of files the rom needs to function.
Well I think I've succeded, thanks. But I still have that Wi-Fi Error. so i guese changing kernel just won't do.. or shall i try DM older Kernel?

[Q] Updating paranoidandroud rom guide

I know there's a lot of info on this subject, but im still confused about a few things related to simply updating to a new version of same rom.
some says i have to wipe all, clear cache and dalvik cache every time, others talk about dirty updating which i guess is without wipe, but do i still need to clear cache and dalvik, or just dalvik cache?, and do i have to flash gapps every time i just upgrade same rom?
like going from 2.50 > the latest 2.52, what i did was:
1. downloaded both pa_grouper-2.52-27OCT2012-190304.zip, and gapps-jb-20121011-signed.zip and put them in root of my nexus 7
2. went to goomanager and clicked "flash ROMs", where i selected my grouper-2.52-27OCT2012-190304.zip, clicked "Order and flash selected" and on next screen checkmarked "Wipe cache/dalvik cache partition"
3. clicked flash, and waited..
4. did same procedure (step 2 and 3) with the gapps-jb-20121011-signed.zip and now im not sure if that all i needed to do, or if there's something i don't have to do next time there a minor update.. or can i skip wipe cache?, or skip flashing gapps (unless there's a newer version of gapps)?
thanks for any answers

but i still wonder if it's needed to wipe cache/dalvik because it seems to remove some login info fx. in gmail, wallpaper and such, and if it's not needed, then i might as well not do that

If you dont wipe them, it can cause troubles.
Also, it shouldnt affect anything, doesnt for me
Edit: Gapps must be flashed everytime for PA. Forgot to mention that

Found this thread by searching.
I have a question. When you upgrade the ROM, and do all the steps listed above, does this also save the installed apps on the device?

Yes. Flashing the rom, then gapps, wiping cache and dalvik doesnt wipe any apps or apps data

CM10.1 RC2 update question

This is my first android phone and therefore cm10.1 is the first ROM I've ever had so I've never updated my ROM before. Goo manager sent me a notification saying that Cm10.1 rc2 is now available but in order to download it do I have to wipe my phone to factory default or can I just install it over my old cm10.1 and keep my apps and stuff?? Thanks

The whole point of the CM updater is that you don't have to wipe anything - not data, not cache. Just start the download, click OK to install when it finishes downloading, and it'll flash itself over your previous installation. The same applies to downgrading to an earlier release - no wipe needed.
Yes, you can keep your apps and system settings. No need to backup and restore - they'll be exactly the way they were before you downloaded the update.
However, if you are migrating to an entirely different ROM (i.e. not the official CM), then yes, you probably need to wipe. Going back and forth between different updates of the same ROM doesn't need wiping though.
You can just flash it normally using CWM. It's called Dirty Flashing. DO clear Cache and Dalvik before flashing

Wipe Cache and Dalvik -> Flash ROM -> Flash GApps -> Reboot.
And don't forget custom kernels

No need to flash Gapps again on CM, unless data is wiped because of the b/u scripts.
The updater script in the ROM also wipes the Dalvik for you.

Actually you don't have to do any of that except flash the rom and reboot. All the rest is automatic.
I reverted to my backup that I made before flashing. Franco kernel didn't work and I had all the crappy apps I uninstalled from cm10.1 like Apollo and stuff .. What's new is rc2 anyways?
updating cm10.1
Hi all
I am currently using cmw6.0.2.3 and rom cm10.1.20130411-EXPERIMENTAL-p3100-M3 and would like to switch to using cm10.1 nightly. Reason to switch is because pie control in M3 is not working and I saw in some video that it is working in nightly. May i know how to update usingmanual mode please? And also will it deketenall my installed apps and data?
Thanking you all in advance
People,
1) Nandroid Backup.
2) Dirty Flash, if something doesn't work or it starts to fails, restore nandroid, backup everything (needed) with Titanium backup or similar, wipe everything, flash, restore, win.

Stuck on logo screen when installing any Lineage based rom

So yesterday I'm trying to flash Pixel Experience custom rom on my Galaxy S7 Edge Exynos and I'm using floyd rom v4, so i flashed it and it's successful but i can't get passed google logo screen and it stuck for way too long. Then i tried to flash lineage os 17.1 and this time it got to Lineage logo but then it boot back to recovery. I tried adb sideload to install it that also didn't work, in the end i tried flashing floyd rom v5 and that worked beautifully. Can anyone help me as i really want to experience the Pixel experience. Oh and I'm using TWRP 3.4.0.

Yep, you format both, especially going from one ROM to another.
Data is your personal settings, app stuff etc,
System is the operating system (To put it simply).
If you have old ROM files leftover in the system folder, when you flash a new one they will conflict with each other.
It needs to be a clean install

folders to format when swapping from one rom to another (oneui samsung rom to aosp, or different aosp to aosp):
dalvik
cache
data
system
when you are on an aosp rom, and are updating the same rom to a newer version, you can normally get away without wiping data
