[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!

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.

[Q] How to install extra RCMixHD v3.0

Hi, I have installed RCMix HD, now how must I do to install extras?
Thank you.

Just like the ROM. Flashing the .zip files.

and this doesn't cause any damage to the installation, is it right?

No, it does not.
Sent from my customized HTC Desire using TTP

Thanks a lot. And the kernel? is it important to install?
For install extras and kernel, must I even do:
wipe data/factory reset
wipe cache partition
wipe dalvik cache
?

DO NOT WIPE a thing... you'll have to Re-flash everything then.
Just Flash it as normally would. (However it depends on the extras - some people said that for the Power notification extra you need to wipe dalvik if it is NOT Working).
Kernel? If you are not satisfied with the stock RCMixHD kernel, then you can flash others, just as the ROM, no wipe.

and if would I delete extras after installing?
I'd wand delete Customizable personalize button...

Make a NAND backup before you install something.
If you don`t like it, you can go back to the NAND backup.

I have installed it without NAND backup...how can i delete it?
how do I do NAND backup? with ROM Manager?

Nandroid backup can be done via custom recovery (CWM or AMONRA).
Now you can't delete it, just if you do a full wipe and re-flash the whole ROM AFAIK.

help im stuck on htc evo screen logo and i cant restore

i was on Calkulin's_EViO_2_ROM_v1.8 and i rebooted to recovery to restore back to cm7 rc4 but it gives me error error while flashing image. so i try to wipe and reinstall another rom and works but it still stuck in htc logo.

Are you performing a full wipe, factory/data, cache, and dalvik?

yes i performing full wipe and everything im uisng clockworkmod recovery 3.0.0.5. did those and install a rom but still stuck in logo screen and i cant restore i made few backup and none them work!?

Have you tried going into the bootloader, select clear storage [factory reset], then flash the rom? Also are you flashing a kernel?

im just flashing regular rom on using clockworkmod. ived done this flashing roms many times and never happen like this before.

Well at this point, it seems like your old backup may be corrupted. Make a new backup, and then try to restore it.

how i do backup when i already delet wipe already so i jsut need to install another rom and do backup and restore it?

Correct, make a backup of your current, flash a new rom, then try and restore.

ok i install Calkulin's_EViO_2_ROM_v1.8 agian backup and try restore but it gives me boot image error same thing.

i had a similar issue. my phone wouldnt even boot past the splash screen but i was able to correct that by flashing the stock evo ruu in hboot from my sd card then reflashing a custom rom over that. im not sure if you have to re-root but in my case i had to run unrevoked again. i had to reflash at least 4 times before my issue resolved but havent had any issues since

can you show me the steps and what i need?

1. Go into recovery, select backup, backup current rom
2. Wipe factory/data, cache, dalvik cache under advanced
3. Flash a new rom, let it boot up, go back to recovery, backup that rom
4. Restore previous backup just made

You can install the official RUU upddate from sprint then download the newest HTC SYNC to your computer then plug in the phone thru the usb and run the RUU file as if you are running an app. Remember this will delete everything includidn your root but you can easily re-root with unrevoked. Hope that helps? I had that problem on my incredible and I did this and it fixed it.

That's a separate partition, that is okay, since you don't have it, no ened to worry about it.

to unroot do i need 2.2 version to unroot?

If you're on hboot 2.10, you'll need a 3.70 ruu.

im sorry please show me how to unroot my phone since i cant boot up im on bootloader.

Use Sprint Lovers ROM the PC36IMG.zip version put on root of sdcard go into bootloader, update, reboot there you go. No re-root needed. I ALWAYS keep this on my sdcard root just in case. Trust me it saved my EVO more than once. You will lose everything but better lost info than lost phone. Try RA Recovery...better than any IMHO

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 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,
