[Q] How to safely test MIUI and revert? - Galaxy S II Q&A, Help & Troubleshooting

So MIUI is available and I want to try it.
But I will likely want to revert to my phone as it is now.
Right now, I am running 2.3.4, baseband I9100XXKI1, kernel 2.6.35.7-I9100XWKI4, build XWKI4. It is rooted, has Superuser and ClockWorkMod, no Root Manager. I have no physical SD card.
How do I get MIUI on to my phone?
What, if anything, will that process delete?
What should I backup and how to restore?
ie. If I do a backup in ClockworkMod, is that effectively backing up the whole phone or just the kernel and ROM? ie. Is restoring a ClockworkMod backup enough to restore the phone to its pre-MIUI state?

Install rom manager
Backup your current rom. It backs up everything
Download miui from the miui website. You can also download it directly from rom manager.
Boot into recovery using vol up, home and pwr button and flash the rom. You will have to reinstall rom manager in miui.
Play with miui
Restore your previous rom from rom manager.

Just make backup and if you don't like miui, then you just restore. And everything will be back as you had before miui. Don't forget to wipe data and cache before flashing miui. Clear Dalviks cache aswell!

I recall being told on this forum that ROM Manager doesn't work on this handset.
can I clarify...ROM Manager basically just invokes the clockwork mod recovery, right?
So a backup in this way would backup absolutely everything, including the contents of the internal sd card?

Where should I be placing the MIUI .zip? On /sdcard?
Similar question re: backup - does ClockworkMod backup include the contents of /sdcard? Or is that not included because, technically, that is regarded a physical SD card?

Only backup your system, app and setting. Don't backup all your data on sd card
You can copy zip file to sd, go to CWM recovery menu, wipe all then choose flash zip file from sd card

I think what he might be getting at is can he place the zip on the internal storage of the device, and flash it? As it seems he doesn't own a SD card.

Just a heads-up: I tested MIUI on Friday, after making a full Nandroid backup of my VR3.0 with CMW.
When I did a restore of my VR backup afterwards, a lot of apps were force-closing, and even fixing permissions or wiping cache and Dalvik cache did not help.
What did work was a flash of CM7, allowing it to boot once, and then restore VR again (with a full wipe of course). Everything is running fine again now. I suppose this has something to do with the CWM recovery version included in the kernels (my VR had a 4.x version, CM was 5.x).

[Q] CWM does it restore everything?

Hello
Here is my story
I was trying to upgrade to ICS by flashing the latest stock ROM XXLPS that I got from Samfirmware.
1- on the first try I did not perform a full wipe, the ROM was a no wipe ROM so It upgraded and all my apps are kept there,. after a while I start facing errors and restarts so I fall back
2- on the second try I flashed the ROM then I did a full wipe/factory reset. It was working well until I rooted it using CF-root and started to restore my apps using TB. I noticed that the problems are coming from Apps installed on external SD, sometimes it was unmounted automatically
Anyway I did a fall back using a CWM restore, I noticed after restore that CSC and baseband are still the ICS ones ? I thought that CWM backup and restore everything??!!
I have also had the same experience once....
when we select advance restore we can find these:
1) Restore Boot (which include boot image and Kernel)
2) Restore System (complete system files)
3) Restore Data (user data like apps and user data etc..)
4) Restore Cache
5) Restore Sd-ext (if we set a partition for applications in the externel SD card)
Unless the CSC is already integreted in system (2nd item) I believe these 2 items, especially baseband, are not backed up normally from CWM, otherwise there should be a restoring option too .....
Especially if you go from one generation to another (Gingerbread to Icecream e.g.) its more complicated to go back a step. You should flash a base Gingerbread ROM from samfirmware e.g. with ODIN (not a CWM version) and then try to restore your Gingerbread backup.
After you flashed the base you may change CSC before you restore your backup. This is the cleanest way to get back.
CWM nandroid is not what we know as a real image backup of a PC.
Thanks guys for the clarifications
BTW regarding the upgrade to ICS what is the best option to do it and restore back the apps or keep them ?

This you have to do with Titanium back up not with CWM back-up...with Titanium Backup pro you can restore applications from nandroid (CWM) backup.
there should not be any problem while you restore only apps on the ICS, some may not work, just unsinstall such...better you select it individually and install... but dont attempt for any system data restore....
This is exactly what I have done, i tried to restore using TB but from backup taken by TB and not from Nandroid.
It was working fine but later start to hang and restart. I noticed that the issue is coming from applications installed on external SD? Is there any issue with ICS or CF-root kernel and external SD card?

try moving all apps from ext sdcard to phone for a while and check for any issues like hang or restart
I found an open issue related to crash and reboots when a large number of apps are installed on sd card.

thank you so much
Wait so all of my old apps/music are gone now? Do I have to redownload or is there a way to get this stuff back (bear with me, first time)
Actually Music is still there, no apps though
Wipe data will delete all your user apps. Yr music isn't deleted because it is in yr usb storage.
Use something like titanium backup or rom toolbox to back up yr apps before u flash. Then in the new rom, just download titanium backup and restore. U will be able to restore because the backups are in the USB storage

Remember to always factory reset when installing a rom, otherwise this will probably happen.
There is some way you can get your google play apps back i think .

[Q] Titanium backup folder missing after root and install ROM

Helped a friend to root and install custom rom.
Basically the step i used
1) Root it with odin and cf-root
2) Root working, so i get titanium backup and run the backup
3) Factory reset and install Omega rom v37
4) failed to install, seem like i get the older version of cf-root. So i re install the cf-root
5) Install omega rom v37 and it worked
6) Install titanium backup. However, when i want to restore, seem all file missing. I scanned through whole device, cant find it too. The sdcard/titaniumbackup is an empty folder
Question
1) Could the backup file in sdcard0/titaniumbackup?
2) Why the backup will disappear by itself?
3) Factory reset/wipe cache/wipe ...cache will delete the backup, right?
4) Watapps backup disappear too?
5) Instagram pictures folder disappear too?
5) Any idea to get the backup back? Feel really sorry as lost my friend's data, please help me if there is a way to get the data back.
Thank you.
how did you do the factory reset? from the settings menu?
Yes, from the cwm menu.
And i did it just like what i did for the last 50 times

Yes, you factory reset, which wiped your internal sd, and you really should set titanium to save to external sd if you have one to avoid this happening again, and backup to pc before you start messing around
I never understand making backup on internal sd - think it would be good to advise user of TB after installing to change the folder at first. (If ext SD is present)
Do anybody backup PC on c:\ ??? Must be more complicated on a phone...

Question regarding TWRP

first thing is i hope this is in the right forum? before i do a backup of my stock rooted unlocked phone, i was wondering if i could change the backup store location to external storage, and if i should select to backup cache and recovery along with the 4 items that are checked when i open up backup? if i dont check recovery will i have a problem when i go to restore that backup without recovery? thank you for any advice
Yep right spot. When you go to the recovery tab there is an option for external sd card. I don't worry about recovery. For my stock rooted I did system, data, boot, efs and you could they're in modern. This way you could almost save restore out of any thing

[Q] how to delete all files that have accumulated from flashing custom roms

I want to remove files that have accumulated from other roms. In others words like stock, but with custom rom. I like Beanstown106 with SD swap.
Thats a little tricky with sd swap but you will have to painstakingly go file by file and see if it's something you have deleted to something that you are still using. If you have any apps that created a folder and are gone for good then you are safe to delete. But avoid any system app folders and anything that you are still using like pictures, music and so on avoid.
M.A.D.NoTe.||
thx for help
I'm installing cleanrom ace 4.9 my goto rom next to beanstown106. No SD swap and I was thinking of formating SD card. Now how do I erase what a factory reset won't delete.
I usually wipe EVErYTahING wenever i flash something new sd card and all just to start from scratch but all i got on sd card is pix and music so its easyily backed up

from recovery, format internal and external sd. that will wipe everything out completely.
I did consider formating from recovery. I'm just scare of deleting the OS and my phone ending up being useless. I did research and what I read it won't. Any advise is welcome THX to everyone.

How would it end up being useless? Its no different than a pc...your reformatting and installing the OS on a clean slate.
I was thinking if I formated the internal it would delete recovery as well. And had no way of installing a new rom. Thx again really help full.

I want to clean up my directory structure. If I format the internal and external sd using recovery (TWRP) to wipe everything, what rom will boot? Will my custom rom boot or will the original verizon rom boot? Will I have to unlock the bootloader again? Thanks.

you will lose all data and need to reflash the rom in recovery...no you will not have to unlock again, nothing performed from recovery will overwrite the boot.img.
I was scared of the losing my OS as well, but it's not that hard. Treat it as two steps. Formatting your sDCard, and then prepping your SdCard by doing a Nandroid backup to your SdCard, and copying a flashable ROM (and kernel if your ROM does not flash a kernel) to your SdCard. Before formatting your SdCard copy anything you want to keep to your computer. I just copy the whole card to my computer.
Reboot and do your data resets and wipes, including internal storage (format data in twrp) Then flash your ROM that you put on your ext SdCard. Your nandroid backup is your insurance. Worst case you boot into recovery and restore your backup.
(But you should still have a working toolkit or ADB on your computer and you can recover from any screw up)
As long as you have what you need on your (ext) SdCard before wiping internal storage, and you only do a data reset and cache wipes and only do 'format data' you will be fine.
