[Q] New ROM without wiping data & cache - Desire General

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!

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.

that's called a Force Close (FC). It usually happens with an unstable ROM/unstable app but more often it happens when you don't wipe (Cache/Dalvik) before installing a custom ROM.
Backup any important data that's not already on your sdcard, go back into recovery, wiple your cache and dalvik, and flash the ROM again. see if that helps you

even if im coming from the old fresh to the new fresh i still have to wipe
I'm not familiar with Fresh's ROMs, if you read his threads carefully I'm sure he'll tell you which version upgrades require a wipe and which don't. Usually a drastic upgrade will require a wipe. In your case a wipe will most likely fix these FCs
With the learning curve for the EVO still growing, its usually a good idea to wipe data/cache/dalvik when flashing new roms. Even updates. I haven't seen too many "No Wipe Necessary" around this forum. As long as you've got Titanium or MyBackup, wiping isnt as big of a headache as it used to be. Hope you get things figured out. Screwing with these phones can get frustrating. Dont know how many times I wished I hadnt messed with anything.
well i just wiped and reloaded fresh so hopefully this will fix everything

CM7 final bootloop

So I have a rooted (latest unrevoked) EVO with stock ROM. Radio is the current version so I did not need to flash a new radio. I have the rom backed up with rom manager and also a Titanium Backup.
I download Cm7-final with Rom Manager and proceed to flash it. All appears well until it loads and I'm stuck in CM7 splash bootloop and never get into the actual OS/homescreen. I boot to recovery and restore my prior rom backup, luckily all is fine.
My question is what have i done wrong? I read the EVO CM7 Wiki and it looks like I followed the instructions correctly. Do I need to ditch using RomManager and try it manually? Any suggestions on why I got this bootloop?
i had the same problem when i tried to update on the g2. i backed up the phone and wipe data and caches and flashed again the it worked you might have to do it acouple of times

Using the RomManager interface I chose to Wipe Data and Cache and also chose the gapps package to install. I guess I could try it again but I was mystified why it didnt work since I "thought" it was so simple.
If you're coming from a sense rom, wipe cache, data, dalvik, system, boot, basically everything but the sd card. After that, flash cyanogenmod, then gapps, then start the phone.

I'm an android noob, you'll have to forgive me. I thought when I selected "wipe data and cache" prior to flashing CM7 in the RomManager interface that it meant it would wipe all of that.
So I need to manually wipe everything except the card? Also, a secondary question, will any of this jeopardize the ability to restore my currently backed up stock sense rom if **** hits the fan?

No it won't as long as you have a nandroid. Look up the "VR Superwipe," and flash it. I'd recommend booting into recovery manually and doing this. Wipe cache and dalvik after flashing the superwipe for good measure. Finally flash the ROM.

I had the same issue....although mine have been caused by restoring system data.
What I did is manually DL the rom, boot into recover, wiped cache/dalvic, flashed from zip (Both CM7 and the proper GAPPS file) and it worked.

nandroid? So the RomManager rom backup I created isnt sufficient? I also have a full Titanium Backup saved too. Why Nandroid? I was under the impression this was just a similar app to Titanium - wrong?
Thanks for the input guys.

I have no tried since I got all these suggestions. Sorry for the confusion. I suspect manually wiping and manually installing will work.
Alpine:
When I first started flashing stuff I relied on the Clockwork app to do everything. I used it to flash roms and clear/wipe data and cache. However, after running into problems like yours I started doing it manually.
What I started doing was booting into RECOVERY (i know it sounds scary but it really isn't) A little off topic but there is a great app that I think every rooted user should use, it's called: Reboot Control Widget It only costs a measly $1 in the Market but it's well worth it. Basically you put the widget on the desktop and click on it. You are then given the option to Reboot your phone, Hot Boot (fast reboot), boot into Recovery, Bootloader or Shut Down. Best dollar you will ever spend on an app.
So anyway, l strayed from my point. The problem you are experiencing is partially due to not having fully wiped your phones data/cache. I know you think you did it through the Clockwork app but from experience it doesn't work that well. There is a "flashable" file called Calkulin's Format All. It is in the DEV section posted in Calkulin's Rom section. It will clear everything except the contents of your SD card.
1. Boot into RECOVERY
2. find: INSTALL ZIP FROM SDCARD
3. select the Calkulin's Format ALL.zip file (your phone will be totally clean after this)
4. Again, choose INSTALL ZIP FROM SDCARD
5. Select the ROM you want to flash. (If it is a Cyanogen based ROM you will have to flash the appropriate Google Apps file after flashing the ROM. If flashing a Sense ROM the Gapps file is not necessary)
6. Flash Gapps file (Google apps if necessary)
7. Once this is done select REBOOT SYSTEM NOW
I feel confident that if you follow those steps you won't run into any bootloops!
I have added the Format All.zip file that I mentioned in my last post.
Little advice:
- take the time to do a Nandroid before flashing a new rom
- use Titanium to restore only the apps w/o the data. I know it's nice to restore everything the way you had it on the last rom but from my experience this has led to instability in the new rom. Also from my experience when you are on a SENSE rom and use Titanium to backup your files and data when you install a AOSP (like CM) rom and try to restore those files and data it won't even let you. Just something to keep in mind if you are switching between CM to Sense or vice versa.

Yes it should.
Manually wipe you factory/data, cache, dalvik, then flash the rom with the latest gapps and you'll be good.

Wow, great post. Very informative and detailed, thanks a lot.
So why is creating a nandroid backup better than the ROM backup function in RomManager? I restored that rom once and it worked flawlessly. How does nandroid differ from the rom backup created in RomManager?
when you use clockwordmod recovery to wipe your phone the dalvik doesn't wipe with the wipe option you see on the main screen, i belive you will see the option to wipe it in the advanced menu

They are the same. ROM Manager boots you into recovery and nandroids for you. People have mixed experiences with ROM Manager. From my experience it is best just to boot manually into recovery and take care of all your flashing and wiping there.

[Q] Frozen Bootscreen - attempted change from LeeDrOiD V3.0.2 GB to RCMix S v1.3

Hi all,
Would really appreciate your help! I'm a nOOb and may have bricked my phone. I rooted and installed a LeeDroid Froyo Rom last year, updated this recently to LeeDrOiD V3.0.2 GB. I got brave today and attempted to change this to RCMix S v1.3 (Sense 2.1+3.0mix) but now my phone is stuck on the HTC Bootscreen.
The process I followed was the same as when installing LeeDroids ROMs:
I backed up my apps
Re-partioned my SD card - 512md using ROM Manager
Used ROM Manager to boot to recovery
Factory re-set
Re-installed ROM Manager
Copied the new ROM zip file to the SD Card
Used ROM Manager to boot to recovery
Installed the new ROM which installed correctly ("Congrats, successful installation, re-boot and enjoy ..." or similar word to that effect)
Re-booted
But now it's frozen on a permanent HTC logo bootscreen.
I would greatly appreciate any help you can offer, or a link to the solution if there is one that may have been requested and solved before, I've spent an age searching the forums but can not find a solution.
Thanks in advance,
Karl
sounds like you didnt wipe the dalvik cache.
I would drop the battery out, replace and boot into recover, wipe data factory reset, wipe dalvik and go for another install.
Can you confirm if you did the above?
edit: oh and i dont know if its made a differance but when i install a new rom, i transfer to the SD card then, wipedata, wipe cache and then install as opposed to booting the phone after wiping data
Before flashing you always have to do a full wipe.
Your systemdata and apps can backed up by Titanium Backup. The backup don't get deleted by the wipe. After flashing the new rom (and eventually re-downloading/re-installing Titanium Backup you can restore all systemdata and apps by "Menu>Batch>Restore missing systemdata and apps".
First tip for the future: Always make a complete nandroid before every flash. If there are problems with your new system, you a running system anyway.
Second: When go from sense-rom to a non-sense-rom (or reversed), you must not restore system data, only the apps. Otherwise there can be heavy problems with your system.

Cheers Vis-tec,
Yeah, it was the dalvik cache, I did exactly what you suggested and it worked perfectly. Never heard of dalvik cache before but wiping it did the job.
Thanks again,

Thanks MatDroid,
Good tip about the system data when moving between sense and non-sense roms - I would have found that out the hard way for sure!
I know nothing about nandroid so I'll start reading up on it!

Another good tip, I assumed that the wipe would delete the back-up, or to be more precise, I was unsure where it backed up the data/apps to. So I uploaded to Dropbox using the Dropbox feature in Titanium Backup ... this takes an age so it's good to know that the backup doesn't get deleted by the wipe for future rom changes!
Thanks again,

Try using RaRecovery http://forum.xda-developers.com/showthread.php?t=839621
It's the recommended recovery for RCMix S. I got stuck in splash because of CWM.

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).

[Q] How to upgrade rom without data wipe

Hello,
I have an Amazon Kindle Fire with gedeROM v1.7. I love the updates because it makes my device better and better.
But can i update my device without data wipe so i don't have to reinstall and reconfigure the entire device every time. And if I can can someone please tell me how.
My usual procedure is download file, data wipe, clear davlik and cache, flash, wipe cache restart and wonderfull a better device. But all the data and apps go with the wipe so any help would be awesome!
Thnx for all the help!!

If you're not switching to a different ROM (ie, from CM7 to CM9, or from hashcode to energy...) then you can optionally skip the data wipe (factory reset), which will retain your data and applications...
Alternatively, you may want to take a look at Titanium Backup.
Thnx for the info.
I have been hearing a lot about Titanium Backup, can you give more info about the program.
With TB you can back up any apps on your device. Then when you update a rom just download TB again and then you can restore your apps that you backed up. I love TB and use it on every device that I have rooted. It is a lifesaver!! Ok maybe a time saver anyway!! LOL!!!!
I had a REALLY bad experience from not wiping everything completely. I'd definitely do a backup, like Titanium or MyBackupPro, and wipe it all just to be safe. To many goofy things can happen if you don't.
It really depends on what ROM your flashing. There are rare occasions you can cross flash without issue. Not recommended. Just updating the same ROM so wipe is necessary, unless mentioned by the dev.
If you do wipe than BUYING titanium backup is the way to go. The free version doesn't auto install apps, each needs confirmation.
I can get any ROM on the kf or my gnex but up and running in less than 15 minutes.
this is what I have been doing and I am not sure if it's bad to do or not. I make a backup of just my data using twrp, then I wipe the caches and do a factory reset. Then I install the rom, and then restore my data using twrp

Restoring your backed up data is akin to not having done "factory reset" in the first place.
You shouldn't encounter any major issues so long as you're flashing newer versions of the same ROM and there hasn't been a large change (for example, switching to linaro).
