[Q] New ROM without wiping data & cache

I have upgraded from my rooted 2.1 to the rooted official HTC 2.2. However to avoid having to reinstall things and setup my phone I did not wipe the data & cache before flashing the ROM.
Is this a particularly bad idea for some reason? Everything seems to work OK... so far!

hm, did you do nandroid backup + titanium backup all data etc?

yes I have a full nandroid backup of my original ROM should anything go wrong. I didn't do a titanium backup though because I thought that not wiping the data & cache would be easier.
If it doesn't work out then I can revert to my nandroid backup and start again, this time WITH a titanium backup.
I'm wondering what sort of problems I should expect?

The problem issue of not wiping data is kinda random... Sometimes when you flash a different ROM despite not wiping data it would work and sometimes it wouldnt.
When upgrade your ROM and flash the same ROM but with different version, you can do it without wiping. The impact should be minimum.
When you flash a different ROM that the currently using, there is a chance that not wiping might result in a boot-loop or the ROM not working as it should be.
The main guideline should be to flash any ROM and do a full wipe if you get a boot-loop or find any issue with the ROM. Doing a full wipe when flashing different ROMs is also recomended.

OK, thanks. Since I have all the backups to go back if needs be I think I'll carry on and see if I have any issues.

Personally, I think it's a risky.
However, wait until you get problems, then do a full wipe, including Davlik cache and do NOT restore apps from a backup after.

How would i go about changing too CM 7.1.0?

Hello i am currently on CM 7.03 and am wanting to change to CM 7.1.0.
Is there any way of updating the software without flashing the new ROM?
Also to update by flashing the new ROM do i just have to wipe cache and reset factory settings then run the zip from CWM?
Thank you for your time.

u only need to wipe cache and dalvik cache (only to be sure) and flash the update..thats all
no factory reset or other wipes are needed

So am i right in thinking that too change between ROMS thats all that you have to do? (obviously having made a nand backup)

yes and u will not lost any setting

Ah that's good. I will still do a back up of all my messages and contacts regardless.
I thought i would lose everything again, considering that the first time that i flashed a ROM i came from stock and rooted with Revolutionary.

you lose everything when u do a factory reset/wipe user data from the recovery
the factory reset/wipe user data is necessary when u change the rom (like going from a sense rom to cm7)
but when u just upgrading (cm7.0.3 to cm7.1) u dont have to factory reset/wipe user data..only wipe cache and dalvik
btw always do a nandroid backup before upgrading

NAND backup, flash the rom, flash the gapps. You might want to clear cache and dalvik-cache too. It shouldn't be necessary to wipe your data.

and what if I also want to flash a new hboot and don't want to lose all my data? can I first update to 7.1 (from 7.0) then do another nandroid backup then flash a new hboot (which require wiping everything, I understand) then restore from nandroid backup? Is that possible or there is another easier way to do it? thanks

That should be possible if you are flashing the CM7 hboot and have not modified any system files as the partitions should still fit after the hboot update. However I recommend you do some more research or back up your data with titanium backup (in case it fails).

nice! thanks!

Installed CM 7.1.0 by just wiping the cache and dalvik and it all worked perfectly.

phone will not wipe!

Phone is rooted and s off and has been for a long time running a custom ROM, I've installed this ROM many many times using the same zip and flashed cwm recovery. But now I want to return the phone to a fresh install with no user data I can't! It's probably me not doing something right but I'm sure it's not. When I wipe and install the ROM the old data and installed apps are still there! How can this be?
The phone boots and takes you through first start up pages: uk, google account, wifi etc but when getting to the phone it's how it was before I wiped!
Help?

Probably it syncs most of that data with your Google account.

That's the thing I haven't entered the google account

Try to format your sdcard all over again if you are using Ext partition. What recovery are u using anyway? Might as well reflash the recovery too.

Wipe
WIPE (wipe data/factory reset + wipe cache partition+Darvik Cache) before you start with installing new ROM. Might help ...

Thanks^. Yep New recovery worked

Oh well sorted now

Be careful guys

Guys be very careful
I flashed Vdt 2.1 and after that flashed provided patch for F180 k. All went fine Boot loader remained locked and rom booted up fine. Previously i was on Philz touch recovery but that patch flashed another recovery. I booted phone in recovery and wanted to restore nandroid backup , once i selected wipe data it wiped my complete phone all data gone :crying: and phone was clean like a factory piece .
Advise is please be very careful using korean rom , patches etc , keep updating your backup data in computer before flashing new rom . I ve just lost over 15 gig data and dont want any one else to go through this .

Thanks for the Info Brother.

After Factory Reset, Phone is Slow as Hell - HELP!!

I'm rooted on my Galaxy S3. Last month I made a backup through TWRP recovery. Yesterday when I restored to the backup, the restore wasnt complete. I tried to restore again and I encountered the same incomplete restore. My customized settings in the apps were gone and some of the apps I had backed up weren't included in the restore. Looks like something got messed up.
I then wiped cache, Dalvik, data and system. I even formatted the phone. I also did a factory reset. This messed up my phone so I installed a new rooted stock rom. So now, the phone is slow as hell and apps arent very responsive. Everything is laggy and slow. And the play store and youtube have slow connection speeds.
What should I do to fix this stupidity??

Did you try restoring a stock ROM via Odin?

I had the same thing happen before. Odin with a stock rom is all that fixed it for me.

Yes I did. But Playstore downloading speed and wifi speed are slow as hell. What do you suggest?

Are you downloading over WiFi or cellular data network? The phone is running the latest rom without root? After flashing, you you immediately go to b recovery and do a full wipe?

Yes I'm downloading over wifi and its slow. The phone is laggy too. Its running JB with root. I tried a full wipe of dalvik, cache and data or system. It doesnt help.

This is really strange because a factory reset usually does the trick.
This may be a redundant question but was the phone flashed with the correct ROM? I see different variations of the T999 on sammobile.com's website.

Hi audit.. Its not a dumb question at all. The rom was the correct one for my phone. Everything was working fine up until a week ago. Its possible that my phone fell and maybe that caused damage maybe.
Not only that but restoring bsckups through TWRP doesnt yield perfect restores. All my restores have not been complete. Customized settings all returned to default and apps were rearramged differently.
Anyeay, just to make sure, how can I do a proper wipe without wiping out my custom settings and apps? Do I just wipe dalvik, cache and system?

You would wipe dalvik and cache only.
Wiping data wipes apps.
Wiping system wipes the rom.

Thanks for a speedy reply. Can you explain why my backuo restores through TWRP dont yield perfect restores? Custom settings return to default and apps are arranged differently.

I am not sure why that happens but I have used twrp on several phones, including the lg g2, nexus 4, note 3, htc one x, and Samsung tab without issue. Maybe you need to do a full wipe before restoring? Does the phone have the latest twrp?

Hi audit. Yes the phone has the latest TWRP. I downloaded it from the play store yesterday.
I got an important question. I backed up my rom a few days through TWRP as I said. Is it possible to open up the backup on my laptop and search for specific pics? I dont want to restore the rom, since as I stated, I have problems doing so. I just need to get those pics. Is this possible?

I am not sure but it is worth a try.
Humour me but is the twrp 2.8.7?

Thats right, current version is 2.8.7.0.

I don't know why it doesn't restore properly. Maybe try re-flashing twrp from Odin? Can't really think of anything else.

How do I reflask TWRP through odin? In doing so, would I risk losing my data, apps, etc? Is it safe?

You download the tar file for d2att, open Odin, put phone into download mode, put the tar file in the pda box, and flash.

Wait, when you say the tar file for d2att you mean the TWRP file, right? Hope thats what you mean because the way you describe it, it sounds like instructions on flashing the whole rom.
Where do I get the tar file for the TWRP app?

Thanks audit. Now, I'd like to know what app do you recommend to find out which apps are causing the phone to get so hot. Thanks.
