[Q] Can I install MIUI-XJ over stock MIUI on Bravo (Without data wipe)

I'm not sure if this is supposed to go here, but I want to install MIUI-XJ on my HTC Desire GSM
http://forum.xda-developers.com/showthread.php?t=957291
I really know nothing about when wiping is necessary, I know it's good to wipe cache to speed up the phone but I'm always advised to wipe my data/factory reset when installing a new rom.
I'm wondering, when installing MIUI-XJ over stock MIUI without flashing, do I really need to factory reset?
I don't have many apps installed, just I want to know when and why it is really necessary.
Thanks for any feedback <3

I'll have a look around

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.

Help... CyanogenMod 10 Jellybean 4.1.2

Hi everyone, I tried the rom on this link http://forum.xda-developers.com/showthread.php?t=1782009 and so far everything is great, I installed GAPPS... I think... I'm kind of a noob :/
Anyway everytime I open the Play Store it just closes in a nano second! And when I open the internet browser or other apps like that it says [Unfortunately, the process android.process.acore has stopped]
I used the HTC Sensation 4G AIO kit by Hasoon 2000 v2.0 for everything.
Can anyone please help me

you haven't done full wipe ..before flashing the ROM i think
go to recovery ...and do full wipe
if CWM recovery -> wipe->factory reset + wipe cache + wipe dalvik
if 4EXT recovery ->wipe/format->format everything except sdcard
then flash the ROm and then gaaps
that will do
btw when you do full wipe ..you lose all data of the phone ..apps/messages/call logs etc etc

What to wipe when flashing custom rom?

Hello all. I know this is a noob question and Im sorry, but I need to ask.
When Im flashing a custom rom (going to try EOS again) what exactly do I need to wipe?
Im using TWRP. I know that I need to wipe the Cache, Dalvik Cache and system. Do I also choose the Factory Reset option? How about Internal Storage? Then there is the Format Data option. Which of these should I do?

If you do a factory reset, you don't have to worry about wiping anything else.
As for what to wipe for installing a custom ROM, it depends. EOS recommends a factory reset when you are flashing their ROMs going from any other type of ROM, including stock. If your on ICS, to jellybean, factory reset. 4.1 to 4.2, factory reset. One nightly to the newer one, you don't have too.
Internal storage is not something you want to wipe... that is any pictures, files, music etc. etc. that you have on the tablet, it will be the same as when you unlock the bootloader, you lose EVERYTHING!! Factory reset, you won't lose anything that isn't on the system partition.
Make sure you are on the latest version of the recommended recoveries

Perfect. The information you gave is exactly what I needed. Thanks Draxin.

You do not need to format Data. This is rare. When flashing a different flavor of ROM, use the top 4 wipe buttons (cache, Davlik, factory, system)
When flashing between different versions of the same ROM, wipe Cache, Davlik and System (not Data).
Then flash the ROM, GAPPs and optional Kernel.
