[Q] Upgrading my rom

I got my HTC Sensation 4G last week rooted it and installed Android Revolution HD 3.0.4.
Today I noticed that there is a new version 3.1.0 and I am wondering if there any way to upgrade the rom without losing any installed apps or data.
Thanks and have a nice day.

just check ARHD's thread and see if the latest one needs a full wipe. if so, you'll lose all ur data; if not, just wipe the cache and dalvik cache, then go on flashing it, reboot, done.

If it's a small update then you could just flash it.

It is kinda small but the question is if I have to install all the apps again.

If you just flash it over an existing install then no, you only need to do a fix-permissions if you get crashes and errors. If you wipe then install then yes you will need to reinstall all your downloaded apps.

Hi,
If you are installing new ROM with the same base(ie 3.0.4 to 3.1.1)
Then you will not lose any settings or apps.
You will lose any mods(battery %,crt etc.)
Just go to recovery and wipe cache partition and dalvik(advanced)
and you are good to go.

[Q] Q: Updating a ROM

If I want to update my MIUI rom, can I do it by only removing cache only or do I have to do the factory reset?

Only cache and dalvik cache (advanced-->clear dalvik cache) is needed. If you're running 2.3.3 or 2.3.4 it's a good idea to do a full wipe before upgrading to 2.3.5.
Remember next time that you only need to wipe the caches and simply flash the zip. Easy peasy!
- If you want to flash a new ROM, then you'll need to do a full wipe.
- If you only want to upgrade from 1.x to 2.x you only need to clear cache and dalvik.
- If you want to upgrade, but the upgrade includes jumping to a new version of Android (2.3.3->2.3.4->-2.3.5 etc.) then it's a good idea to do a full wipe. It's not needed, but again, it's a good idea.

i personaly never do a factory reset or full wipe unless its recommended by the DEV. this way all my settings and aps are saved and still in their respective spots when switching over. most of my experiences are trial and error based.
just remember always NAND backup before you do anything. its just a android life saver. this way if something doesnt workout you just go back and start over

[Q] Update or clean install?

Hi! Sorry for the noob question but I'm here to learn.
I recently rooted and flashed my HTC Sensation with this rom using clockwork:
http://forum.xda-developers.com/showthread.php?t=1494373
Now I'm wondering if I can just update it when new releases are available or do I have to wipe it all and do a clean install? Don't want to loose settings and everything.

clean install
i think you should clean install

re:Update or clean install?
its always recommended that u do a full wipe prior to any upgrade unless the developer states its ok to update without full wipe

Usually when new releases of roms are available and you're running a previous version of that rom, you are able to update. Clean installs are recommended though, but since you don't want to lose data, you could follow these steps:
- Make a nandroid backup
- format all partitions
- flash the rom
- advance restore the data (from your previous nandroid)
- clear dalvik cache and reboot
N.B. Only do this if the rom was an update to your previous rom.

It´s better to do a clean install.

If you have the latest paid version of Titanium Backup, you can pull all of your apps and data from the nandroid.

Only have free version but might be worth the money I guess.

Option

If it is updating from same rom to newer version, just wipe catch, dalvik, and battery stats and you'll be fine.

Battery stats doesn't need to be wiped (even if it is a different rom). A user should only wipe it if they are having issues with the battery. Also, the system may need to be wiped for a "cleaner" replacement of updated files.

Flashing a JB ROM

Hey, I'm currently on MIUI ics. I know I have to wipe/factory reset everything. But is it safe to flash on the current CWM? Or do I need to update it or something? Do I just flash the new JB rom like I would switching from MIUI to a stock ics rom? I'm a noob, sorry if this doesn't make sense.

What version of CWM are you running?
You should be fine, but it never hurts to check. You flash a JB rom just like any other. Wipe wipe wipe and flash.

The whole wipe wipe wipe is completely unnecessary. One wipe is sufficient and any additional won't do anything.
It's like saying that unless you wipe exactly 3 times the Android Gods are going to demand a human sacrifice for your phone to boot.

lol i think dvorak meant wipe cache, wipe dalvik cache, wipe data (wipe wipe wipe) but that's my take..
anyway, if you can flash MIUI ICS with whatever CWM version you currently have, you should be able to flash other JB ROM. Nandroid as always.. Goodluck!

This is what I did :
1. Boot into recovery and perform a nandroid backup of my MIUI installation.
2. Wipe.
3. Flash XenonHD 9 JB ROM + marmite 4.2 kernel.
My phone is running really smooth now. Good luck.

Yep, that's it. Of course wiping everything 3 times would be unnecessary.

if you get a cluster f*#@ of problems then clean install. It isn't that hard. Use Titanium Backup and good to go.
In Recovery:
1. wipe data/factory reset (this formats /data, /cache and .android_secure on sd)
2. format /system, /boot
this leaves you with only bootloader, recovery and radio...dalvik-cache resides on /data, so it's gone already.
3. flash rom
4. gapps & custom-kernel (if needed). No need to let the phone boot & settle before flashing them (most custom-kernels have a script that automatically wipes /cache & dalvik during kernel-install)
5. reboot
6. Run TB -- restore missing apps with data --1st option under restore
just updating rom:
1. flash rom-zip
2. wipe /cache and dalvik-cache
3. reboot
Do this before reporting any issues on the thread since the problems are often related to this and not the ROM or kernel.

[Q] What to wipe?

This is probably the wrong place to ask but I wanted to know what I should be wiping in TWRP before I flash a new ROM. It's been a long time since I flashed a fresh ROM (I'm on CM11S for quite some time) and I can't remember what I wipe to give myself a clean start.
Thanks

Depends what you mean by clean start, if you mean you want fresh out of the box experience (no apps, no pictures, no anything etc) goto advanced wipe and select everything apart from USB-OTG.
If you want to retain all of your media (pictures, videos etc) the standard wipe in TWRP should cover you (wipes dalvic, cache and data), you don't need to wipe system as TWRP will wipe it automatically before it installs any custom rom.

Thanks. I do want a out of the box experience but with CM12 nightlies instead of CM11S. It's been too long since I flashed anything to my device...

Wipe system, data, cache, dalvik cache.
