What is the proper way to rom hop? - EVO 4G Q&A, Help & Troubleshooting

Greetings,
I want to be able to seamlessly switch from CM7 to MIUI to Sense, etc., keeping all of my settings, apps, etc for each setup. I assumed that I can do this by simply configuring each and doing Nandroid backups. But, when I try to restore my Myn's backup, I get an error.
Anyone know the proper procedure rom-hopping like this?
Thanks!

1. Backup current apps and data in titanium backup
2. In recovery, backup current rom
3. Full wipe [factory/data, cache, dalvik]
4. Flash rom, reboot.
5. When booted into new rom, restore apps and data, NOT system settings.
6.
And if you want to switch back, go to recovery, backup current rom, then restore the backup you want; no need to wipe.
Also you'll get restore errors if you renamed the folder using invalid characters, or its corrupted.

Yes, you can just keep nandroid backups of each ROM you like after you get them set up and running how you want. Then you can restore whatever setup you feel like that day.
You can also back up your apps w/ titanium, that way if you install any new apps, when you restore another ROM, you can use ti to restore any missing apps that you've installed since the backup was made.

To the OP, your post is incomplete without the error message
Your steps seem like the proper way to go between roms. What you need to be aware of is, some apps store their data on the sdcard. Depending what is stored, you may get issues. Beautiful wigets comes to mind. It stores the skins on the sd card.
Are you getting error messages restoring from the backup image itself? What error. Are your image files intact?

Might be your version of recovery. I had a problem going from CM7 to anything else. I switched the recovery version in Rom Manager and fixed it

Sorry, I overlooked that. What error are you getting?
1. What % was your battery at? If it's below 30-40%, it won't restore or backup.
2. Have you renamed the backup? You can only use certain punctuation in the names or it won't work.

Good advice. One thing I'm curious about though. When you do a rom backup, it saves your apps/data etc. anyway, right? When you "restore" a ROM everything is exactly like you had it. So why is it necessary to do a Titanium Backup of all your apps/data (other than prudent good practice obviously) when your ROM backup will have the same. Is there another reason I'm missing?
Second, when you say backup "apps + data" but NOT system settings, what exactly do you mean? When you do a batch backup w/ Titanium Backup you can choose to do Apps or Apps + all system data. How can you quickly and easily backup apps + app data without all system settings? Manually go in and select certain (green) system data?

I do it in case I download any new apps while on one ROM that may not be included in my nand backup.
I don't restore app data, but theoretically you could restore the newer app data as well.

The reason for backing up your apps and data is because when you install a new rom, like going from CM7 > MIUI, you should always do a full wipe, which will erase your user apps; erases all phone content. When you boot into the new rom, the titanium backup data is on the sdcard, and can be restored from there; that's why. And doing a full wipe when flashing a new rom kills off a lot of problems, like random fcs, ect.
No, you do the batch operation for backup user apps + system data, just to be safe that you get the data for the apps. That makes it easiest. When you RESTORE, you go into batch, there's an option for restore only user apps and data, right above apps + system data.

Question about Titanium Backup

Hi,
I was curious, when you install a rom & do a Titanium Backup restore of your data, are you possibly overwriting any system data?
Is it safe to use Titanium Backup to backup your apps, switch roms, restore, etc? Will that cause some sort of problem when trying roms?
Thanks,
Rich
I have limited knowledge about this, so take my thoughts with a grain of salt.
in my experience, doing a FULL back up and FULL restore resulted in errors. in my experiments with roms, i would back up only user apps with titanium then use an app for call log backups and another app for sms backups.
i really wish there was a way to backup everything BUT system data, that way when i relead a rom, all my icons will come back in the same order, my bookmarks will be intact and my settings would be the same. i'm not sure how to do that yet though.
I backup all user apps and then select the system data I want (desktop/messages/dictionary/boomarks). I too ran into errors if I backed up/restored everything.
Once I make the backups though I order the list by date backed up so all the stuff I skipped is at the bottom of the list; makes it somewhat easier to restore.

[Q] Best way to back up your phone when switching roms?

What are you guys using to back up your phones when switching Roms? I want to back up contacts, wifi settings, APPs etc.
If I'm switching ROMs I set them up from scratch again, after doing a Nandroid of the current one
Titanium Backup works really well. It's on the market. Probably on here somewhere also.
Will Titanium restore your screens? Its a bit tiring getting them alls setup and then starting from scratch on my droid incredible I never really set up the phone because I switched Roms so often.

Alright, so for backing up your system you're going to want to use CWM and make a NANDROID backup. After you're done with that you will probably want to back up your apps. To back up app as well as data (such as angry birds scores) you will want to use Titanium Backup. Just remember not to restore system data, just apps/app data after flashing your ROM/Kernel.
For contacts (assuming you are on verizon) you had the option to chose where you store your contacts. Those options were either in your Gmail account or in "Backup manger" if you cant figure out where they are you can always make a file with all your contacts and place it on your SD card by going to the People App>menu>import/export>Export to storage.
As far as wifi settings go i am not aware of a way to do so.
And if you wanted to keep the launcher as it is (like where your apps are, folder, widgets, etc.) you will have to be on a custom launcher such as ADW or GoLauncher. This happens because the launcher is an app and when the app data is restored (from titanium backup) the placement of things are exactly how they were when you made the backup!
1) Nandroid. Always nanroid just to be safe - if something breaks, you need to have a working build to fall back on .
2) Contacts - I don't worry about it - they should all be synced with your Google account anyhoo.
3) Wifi settings - should also be synced with your Google account, and will be automatically restored when you set up the new ROM (assuming you tick the "restore data to my device" option in the google account setup screen).
4) Apps - TitaniumBackup for apps and data - not for system data though.
5) Launcher - some launchers will have an option built-in for backing up and restoring your screen layouts, folders, etc. Widgets will rarely be able to be restored no matter what method you use. You can also use Titanium to explicitly back up and restore your launcher's data - if you're still on the stock launcher, filter for System apps and look for an entry that starts out "[DESKTOP] Launcher ..." (it'll be in green) and backup/restore the data for that.
When you boot after first wipe it asks you for Google account details, then it will pull down your contacts, wifi settings etc. which we want.
But it also starts re-downloading all your Market apps, which we don't want because we've got them in Titanium Backup and we want to restore them with data (save games) and be linked to the Market for updates.
What's the correct way to handle this?
I've created issues before where some apps don't list in 'My apps' in the Market, and don't auto-update unless I search for them at which point it says 'Installed'.
I usually enable airplane mode immediately after the Google account setup, reboot, restore from titanium, reboot, and then turn the radios back on.
ClockworkMod Rom Manager. Its the best tool there is. yu can flash roms by pressing a simple button.
make sure you understand the difference between clockworkmod and titanium backup before you start modding your device. CWM will restore your phone exactly to how it was when you made the backup, everything from your screens, apps, setting, contacts, call and text logs. When you restore with CWM it will erase everything that was done after the backup point. Another thing to keep in mind is that you cant choose to restore specific things in CWM like you can with TB, you have to restore it all in one shot.
TB will restore apps, system apps and data associated with those apps. TB can also be used to backup settings, wifi access points and bluetooth pairings.
So if you get a bootloop or softbrick you have to use CWM. You need to do a factory reset/wipe before you flash a new rom, this is when you would use TB. Use TB to restore the apps, data and settings.
SMSbackup and calllogbackup in the market is also good for backing up or texts and call logs if you want to keep them. google will backup your contacts if you allow google to do this but you can always just save your contacts on your sim card
never ever restore system apps and data.
Especially if it was meant to be a full wipe.
Even then, clean start is always best so wipe and stop reporting bugs if you didn't do a wipe.

On that note, some data for system apps can be safely restored - just never do it as a batch process. If I'm going to try restoring any system data, I do another full nandroid first (just in case) and then restore data one at a time.
I'm shocked no one has mentioned this app yet. Appextractor let's you restore things from your nandroid, Obviously some things shouldn't be restored, but many things can be safely restored.

The only problem I had with app extractor is the amount of SD storage space it uses - and doesn't automatically clean up. My nandroids are already ~2.7GB - I don't really want the whole thing also stored uncompressed. I quickly run out of storage space that way.
Oh, and it's painfully slow.
AppExtractor is useful if there's an important app you forgot to back up in Titanium, but doesn't really make sense to me as your primary restore method.
Isn't the Titanium data wiped when a new ROM is flashed? I assume that before flashing anything, copy the /sdcard directory to another computer?
And after flashing a new ROM, I assume that Ti has to be downloaded first in order to restore the other apps

Unless you're using the factory recovery, the Titanium data will remain intact. You will have to reinstall Titanium from the market - or use the tool built-in to Titanium to create a flashable *.zip. Just flash that *.zip before you boot your ROM the first time and you'll have Titanium pre-loaded.

Thanks for this. I had seen adb backup alluded to elsewhere but not a concise post detailing the usage. I'd rather not have to use my computer to handle backups, but it sounds like a pretty cool option.
Try MyBackup PRO. It does exactly what you need. I have used it before and it is good.

Poor Performance on Sense 3.5 ROMs

Hey guys,
i used good old InsertCoin ROM most time, but i'd like to use new Sense 3.5 now.
I tried Runnymedia AIO and Runny ROM. Both perform ok at first, but then i restore my apps using Titanium Backup. Now the device performs extremely slow after i use the market (play store).
Increasing CPU Frequency doesn't help either. How can i find out, whats slowing my device down?
Using STOCK HBOOT with 1GB Ext4 Partition.
Radio: 32.49.00.32U_5.11.05.27
Instead of Restoring apps, why not try re-downloading them from the Play Store. My Phone is super smooth. No problems yet.
It seems that you're right. App-restoring might be the problem. I removed most apps which i restored with TB and now its smooth again.
But of course i want to keep my App-Data (/data) from my InsertCoin installation.
I'll try installing BackupEverything on IC, backup my apps with this app and then restore to Runny ROM.
Any idea why that might be?
I also have a slow RunnyMod after restoring via Titanium to restore my apps, but most of them have no other way to backup...
Slow, after restoring with BackupEverything too. And BE doesn't even backup /data/data
Somebody knows a tool which actually works?

I backup my apps using AppMonster PRO. Have done since I got my Desire 2 years ago.
It allows for plain name backup of .apks and using its newer backup method, allows for batch reinstall of apps. Also can specifiy how many versions of an apk to keep / as2d notification and automatic backup of .apk when installed.
Doesn't do cache backup and user customizations that can be carried over from one install to another in way that Titanium Backup does, but works fab for me, I just reinstall wot I want!
In this way I dont get any mess up's when switching roms were I restore a TB backup and it puts the data in the wrong place.
I always backup and restore with ic_backup_apps.zip and ic_restore_apps.zip. I can't find the original links (there was a link in the Insertcoin thread) and I don't know if I'm allowed to post mirrors here. But a google search should help you get those files I think.
ic_backup_apps stores all the apks in a .tar file on you sd card and also wipes your system, be careful
ic_restore_apps unpacks this file and puts them back
To install another ROM I always do the following:
backup apps with titanium (only user apps+data, no system data)
backup sms, call log and "some" system settings with Mybackup root
power off, reboot in recovery
a nandroid backup is advised, you should do this regulary anyway imo
flash ic_backup_apps.zip as you would flash any other zip. But be careful, this also wipes everything
full wipe (data+system+boot+sd-ext+cache+dalvik) + battery stats, so everything except sd card
flash the rom.zip
flash ic_restore_apps.zip
power off, (remove sim, to prevent incoming sms while restoring), reboot
switch off automatic backup (it's not needed now)
restore with mybackup root
restore (some) user app data with titanium
I've wiped and flashed multiple sense 3.5 ROMs this way and never had problems with slowness or FCs.
Your SD card could also be a bottleneck.

What do you recommand as backup strategy when playing with custom ROM?

Hi,
I begin timidly to try flashing some custom ROMs. Each time it is quite time consuming to restore system settings. So far each time I flash a new ROM, I re-enter all the system settings, then re-install Titanium Backup and restore user apps (that I backed up previously). I didn't try the batch job "Backup all user apps + system data" Titanium Backup. Because I am concerned that restoring the system data from one ROM over another ROM may freeze the device.
Question: What are the best practices to backup & restore user apps + system settings ?
Thanks in advance for any help.
when changing roms:
best practice of all: don't restore anything
good practice: restore user apps
normal practice: restore user apps+data
bad practice: restore system apps
really bad practice: restore system apps+data

restoring user apps if just as fine as not restoring anything, unless you are the roms you are changing between have different ui's or android os's like going from ics to jelly bean. But for the most part its fine. The reason you shouldn't restoring certain things is risky is because one rom may have a certain data structure with some features built-in as apps, which are incompatible with another rom without that structure. Its just a matter of the way the developers code their roms
restoring the app also restores its cache i believe, which may cause issues because caches are hash signed by each rom flash, thus switching to a new rom and restoring may cause the app to fail (it expects a different hash sig, from the previous rom), until you clear dalvik cache/cache. not risky, just makes you loose time as well, since you'll have to boot again to recovery and wipe cache again after restoring.
anyways, restoring user apps is a good practice, and apps shouldn't have anything to do with system ui. system apps and definitions is another thing.
i often fresh-start flash. i only use 4 or 5 apps, so.. not that big of a deal. i used to install any junk on my pc's, a long time ago. furthermore, i rather have a clean rom with few apps than a rom full of apps which makes it way harder for me to control whats going on.
Oh cool thanks for the explanation. I "Wipe data/factory reset" + "Wipe cache partition" before flashing the ROM. I hope that it should be safe enough to restore the user apps + data. Just did that yesterday and so far it seems like it's working OK.

Don't forget to wipe dalvik cache as well.
Allons-y
Great question and useful information for those new to this. I for one would say you CAN successfully restore SOME system data if you do so carefully. I for one always backup and restore Phone / Messaging Storage via Titanium Backup as this will copy over my SMS and MMS archive, as well as APN settings. Note this is only recommended when switching between Jelly Bean roms.

This is what I personally do when I play around with custom ROMs...
Backup:
-Backup user app using App2zip (Zips all user apk), you can also backup system apk, but not recommended
-Backup user app+some system data (includes data usage, sms history, etc..) using Titanium Backup
Restore:7
-After flashing ROM and mods, flash the zip file made by App2zip
-Restore ONLY the data of user apps and system apps
-Reboot to recovery, and clear cache and dalvik
-Reboot
Successful all the time for me

Thanks for suggesting App2Zip, can you please clarify:
Q1. What is the difference between "App2zip" and "Titanium Backup"? I suppose App2Zip doesn't save at all the user data?
Q2. How do you use Titanium Backup to backup data only? The closest I see is the backup batch job named "backup all user apps + system data". Is it overkill b/c I just want "All user data + SOME system data".
Q3. Where in Titanium can I select "some system data" and what does "some" exactly mean in this context? Providing a wrong system data restore would bring troubles. Can you please give an exact list of the system data which is safe to restore? I am interested in Wireless pwd, and settings related to Sound, Display, Language Input, Lock screen. So far I have no idea how to backup these settings.

A1: App2zip takes all the user apk and puts it into a zip file. So after you flash your ROM, you can just flash that zip file too in the recovery. It's faster for me, because I don't need to press "install" everytime
A2: You can't do data only... You can restore only the data after you backed up. Also you get to choose which system data you want to backup.
A3: I don't 100% know either, but here's things that I backup:
-data usage
-accounts
-SMS (For the SMS history, but you can also use SMS backup+)
-clock (For alarms)
-country,language,timezone
-email
-exchange services
-gmail
-phone/messaging storage
-wifi access points

Yeah that's true, this Install button in Titanium appearing at each app is really annoying. Does App2Zip also save and restore the user apps data/settings? I hope yes, b/c otherwise I can't really remember exactly what I have changed on each app over time.

That's not a problem. I was looking for an advice about backup/restore not for how to save money. When I used Titanium to restore it stops at every app and asking to click on Install and when the app has been restored, it asks for another click on "Done". I am just reporting what I am seeing. Now that you said, I have checked the description of Titanium Backup Pro and may be what you said is the "0-click batch restore" feature which is available in the Pro version. I will give App2Zip a run and will see which one I like better.

Can you nandroid restore for apps & settings on new ROM or new version of same ROM?

Can you nandroid restore for apps & settings on new ROM or new version of same ROM?
Many people (myself included) are "flash-happy" and install new ROMs or ROM updates very frequently. While I love flashing new stuff, I hate the process of getting my phone set up all over again. Titanium Backup is currently my go-to app for backing up apps and restoring them after a flash. Nova Launcher has been super-helpful in keeping my widgets. However, many apps don't work until you open them after a restore (1Weather, Adfree, LightFlow, Lux, etc). So generally, the following is my tedious process for flashing:
1. Assign labels in TiBU to the apps I want to restore and run "backup all apps + data"
2. Wipe Data, Cache, Dalvik, Battery Stats
3. Flash ROM, GApps, Kernel, etc. Fix permissions
4. Install TiBU and then painstakingly restore apps (only non-system), then restore data for those apps.
5. Open each app and configure where necessary
6. Go through all the ROM settings and set them the way I like (nav bar icon size, clock posiiton, battery icon, etc etc etc).
Just the thought of going through this whole process makes me hold off on flashing too often, and I usually end up saving flashes for when I have a big chunk of time. Some people, I've noticed, flash new ROMs like they've got nothing better to do. It makes me wonder... do they have some trick for quickly restoring their phones after each flash? Is there some way to condense or streamline steps 4-6 in my process?
A Nandroid backup saves the System and Data partitions. What info does each partition contain? I realize that each ROM is different and it might be problematic to restore settings of one ROM to another, but what if you're simply upgrading to a newer version of the same ROM? I'm wondering if I can make a nandroid backup of CNA 3.6.6 and then restore only the Data partition after flashing CNA 3.8.0 so that the new ROM is in place but all the apps and settings are restored from the previous setup. If this does work, is it stable and smooth?
Or if I'm completely off about using Nandroid for this purpose, does anyone have any methods for getting back up to speed quickly after flashing new ROMs?
In titanium backup you can go to settings > create update.zip so next time you flash a new rom gapps etc you can install the update.zip as well and have TiBu off the back. If you have the pro key it will be more beneficial to you. You do have to log into you google account if you have the pro key before opening TiBu. I use Paranoid Android and I can backup my rom settings idk how CNA does it. That one you might have to manually do.
Between ROM updates you don't have to wipe data. Just Cache and dalvik.
I have recovered my data partition between wipes before but stopped because everytime I update or flash a new rom I usually go for a new look.
Here is my process between flashing new roms
1. Backup everything in TiBu (I already have the update.zip so I skip that. You only need to do it once or if the app gets updated)
2. Go into recovery wipe data, system, cache, dalvik
3. Install rom, gapps, kernel, TiBu
4. Restart
5. Load up sign into google account
6. Open TiBu and restore everything
Some apps naturally won't restore everything like Adfree for example will put the hosts file in your system for you, when you back that app up your only backing up the settings. When you back it up it only backs up the settings. Dropbox and Skydrive I have to manually sign back in. I never had lightflow so I don't know how that works. Its a little tedious but I usually give a rom a few hours before I actually go through all that.
Hope it helps
If you don't want to have to log in to your Google account before using the full version of Titanium Backup, just use App2Zip to make a flashable zip of TiBu and its Pro key. Then just flash it last, boot, and batch restore the rest of your apps and data.
