[Q] About Darktremor A2SD

I am using the rom which is Darktremor A2SD compatible. Every time I change another rom then all apps will get force close. I need to reinstall those apps.
Is it normal?
Anyone can help me? Thanks!!

When you change ROMs, it's advised to ALWAYS WIPE EVERYTHING. That includes EXT partition.
If you want your programs to run after moving to another ROM - back them up using Titanium, change ROM, and restore them.

Actually I'm not sure wiping EXT is necessary but certainly data, caches etc.. If problems continue, then wipe EXT too.
EXT should just have the APK's on it, they should just work.

If you're wiping /data, then you're left with APKs on EXT and no data structure for them in /data/data. Might be just the reason for force-closes.

most roms detect and "re-install" the ext apps on first boot. All 200+ for me
Wiping ext would be the very last thing I'd do to solve a problem.

I used to do this. But i learned that it breaks some apps, and the built in rom restore function will restore any apps you got from the market. You need to do a full wipe when going to a new rom. upgrade may not need this, but some devs like king dont know how to make upgrades so all of his new versions require a full wipe.

Thanks you all! Seems that full wipe is necessary

[Q] Phone crashes during apps installation

Hi everyone,
Since a month I'm trying some custom ROMs, but I'm experiencing the same behavior with every ROM (but one, CM Build46), the Phone crashes and reboot when I try to install an app.
I tried :
- flashing the kernel to HCDR4.1
- installing the apps using Titanium Backup (installed through Clockwork Recovery)
- ROMs :
- CM 6.1 RC2
- CM 6.1 Stable
- Builds 48,50,52,53,60 (until today)
- Wildpuzzle
- DK Custom Froyo
I'm tired of the Build 46 now ! And I accidentally erased the Original ROM
Please, tell me someone else got the same problem and found a solution !
Thanks
The solution was to wipe the dalvik cache & format the SD Card.
But please, don't make the same mistake as I, save "your" files, but also the Nandroid backups, it's safer

Do you use an ext Partition ? -> >Yes, is the partition full or Corrupted ?
Did you done a full wipe / clear cache and clear dalvik cache before install ?
If all not help. Backup your personal files from your SD-Card and reformat the card. One time , i had a similar problem, which i solved with formating my sd-card. Don´t copy the . Folders . Backup only your Files (Titanium Backup etc.). Try it first without an EXT Parition. Format the Card with Windows to FAT32

I don't use Ext partition and i usually wipe cache partition and factory reset but didn't try the dalvik wipe cache ...
In last ressort i will try the format.
I'll inform you if it works.

Ok! Just try Clearing all the 3 things (Clear Dalvik Cache, Clear Cache, Full WIPE),after that Reflash Custom Rom, then clear Dalvik Cache and normal Cache. Then boot an wait. First boot could take a few minutes. After full first os loading (another cup of coffee later , ~5min) try App Installations again.

Damnit ! Still the same problem after the clear cache etc !
last option : I'll format the SDCard and reflash the rom afterward...
It cost me so much time :-(

OMG, I saved "my" files from the SD Card before formating it...
but I obviously forgot that the Nandroid backup was ALSO on the SD Card...
I'm gonna cry

Lucky !
The format worked perfectly and now the phone does not crash when I install an app !!!
For the moderator : you can close the thread because it's fixed !
Thanks for the help Deep-Knight and Thanks for this answome ROM (v4.2) ;-)

[Q] Wipe issue

I've been learning to edit and make ROMs for couple of months, some of the early works had been uploaded to a Chinese Milestone developers' BBS.
But there is a simple question which still confused me a lot. (- =)
Some senior developers in that Chinese BBS reminded their supporters in their threads to wipe before and AFTER applying the Rom in Open Recovery. But, why should we wipe AFTER applying the Rom? I've viewed some threads here, but none of them require to wipe after applying.
So I wonder if it is really necessary to wipe AFTER applying a new ROM. I'm very appreciate if you guys can answer my question and tell me why. Thx~~~
BTW, Xda is an excellent website. And it's much more professional than the BBS I used to visit. May you have a nice day~

It's a common myth. I'm not sure why it gets repeated over and over again.
One wipe is enough. Dalvik-cache is not populated again until the system is booting for the first time. While you are in recovery, it also doesn't matter if you wipe before or after you apply the update (unless the updater script in some particular update.zip also installs something to /data or /cache partition, which is not very common).
You can read cvpcs's thoughts on this matter here: http://cvpcs.org/blog/2011-06-05/time_to_wipe_data/cache

Thanks a lot~ (I'm looking for some threads which can explain how "wipe" works. Actually I still got some problem about that, like " Why system app still maintain after wipe? Is it because those system app has a backup in Flash Memory, and it will restore after wipe the EEPROM?")

(This message is only for testing whether it is reply to the original poster or the people who answer it....)

System apps are installed into a different partition (/system), which also holds the OS files. Wiping data and cache only wipes the /data and /cache partitions and leaves /system alone. Otherwise the phone wouldn't work at all.

Updating CM7

Hi all
I would like to know all about updating CM7. Currently I have 7.1.5 installed, I Have an ext3 (or ext2) partition for A2SD.
How now would I go about updating to a more recent release? On MIUI it was simply just wiping the cache & the dalvik cache.
Please can someone assist with a slightly detailed answer (I don't find very consistent results).
Also, let's say I'd like to do a clean flash of CyanogenMod (assuming that's not what's required in the first place), but I don't want to format my ext3 partition but simply keep the apps on the fresh rom - how would I do that? Or should I ask what I should be backing up and restoring? If it's not too "clean" to do it like this, please let me know.
Any and all information is welcome. I'd just like to have a clear picture on what I'm dealing with.
Thanks.

Upgrades: Just erase dalvik and cache and apply update
Clean Install: Erase everything. Ext partitions are not affected by the format. Only thing is that it will erase your app data (games saves, etc). The actual apps will be left in tact though.
Definitely recommend a clean install if your coming from 7.1.5. Good luck!

[Q]Wiped clean to install rom, now can't access sdcard

Hello.
first I want to apologize for my, sometimes, bad English!
Second, i want to apologize for my novice touch in this topic!
The story:
I've been using SweetRom for a while, but tonight i wanted to try another rom.
I loaded up SuperBean(not really relevant to this story) on a microSD.
Rebooted my phone into recovery
Philz Touch 5
I choose "Wipe Data/Factory Reset" and then "Clean to install a new rom"
Then i tried to "install zip"
"Choose zip from sdcard"
But then i get: E:Can't Mount /sdcard/
I've tried to format the sdcard, exfat, fat, fat32, ntsf but nothing worked, still the same error.
I can access the internal storage and i can boot into download.
I thought that maybe i'll try to install the newest Philz but when in download mode
my computer wont recognize my phone (i'm using Windows 8)
i'm stuck! please help me out!
I've searched everywhere for answers but i can't find any!
What are my options?

Boot into Philz recovery again and go to mounts and storage and mount USB. Then connect it to pc. Check if the any drive shows up. Then move the new rom to the internal storage.

what DOES the "clean to install a new rom" option do anyway?

It does a full wipe. Basically it formats: cache, /system, /preload, /data

is /preload equivalent to /dalvik-cache? but then what's the point of format /data/factory restore if "clean to install new rom" is present?

No. It's different. Preload is a separate partition and dalvik-cache is in data partition.
The option you mentioned only exists in Philz recovery not in standard cwms

So, to be clear, is it necessary or advisable to do any of 'Wipe Data/Factory Reset', 'Wipe Cache Partition' and 'Wipe Dalvik Cache'? Or is 'Clean to Install a New ROM' merely an amalgam of the above (plus added formats?)?
Thanks

It's usually not necessary but it is ALWAYS advised to format /data /preload /system and cache before flashing a new ROM. If you don't do those wipes then you can sometimes end in a bootloop, random force closes, battery and performance issues et cetera. Basically if yoou want to flash a new ROM (unless it is an update to your current ROM) then always do a full wipe,
If you are just updating your ROM (ex. updating one nightly to another) then you just have to flash the ROM in recovery and wipe cache, dalvik cache (in advanced)
.

Thanks very much for that - much appreciated.
I've read elsewhere that many seem to recommend wiping cache and dalvik after they've flashed a ROM? Is this something you'd advise and, if so, why (or not!)?
Many thanks

If you're updating then yes, it's enough that you flash the ROM and then wipe cache and dalvik cache.
If you're reflashing from start then you should first do a full wipe, flash the ROM, gapps, su and that is all. No need to wipe the cache or dalvik cache again

Ah right. So if you're flashing a new ROM - then clean install is all that's necessary. If upgrading to a newer version of existing ROM, then it's better to wipe cache and dalvik post-install? Why? What does it do and how does it help?

reset before installing zip, now no super su ... cannot mount usb
Hi,
The title says it all. I have been reading and searching. Many similar stories. I apologise if this is in the wrong place but this is very similar to my problem.
I have a galaxy i9505 trying to install a DjeMBeY ROM from TWRP.
I factory reset and wiped cache's BEFORE I flashed the .zip file so then had no .zip file to flash!
Also have erased my system backup and the USB WILL NOT SEEM TO MOUNT to copy it back onto the card.
I have read and read I am very struck.
I am not familiar with all the processes yet. Please help.

i recommend going to here

You can go with the download mode and install a stock ROM or use the 'adb sideload " feature of cwm recovery to install the zip of your ROM if you have it saved on your PC.
