[Q] CM-6.1.0-RC1 ----> CM-7.0.0-RC1 ~ Upgrade Steps

Hi all,
This is probably a pretty basic question for you, so please bear with me, and if it is basic, hopefully there is a straightforward answer .
Having settled on the awesome CM-6.1.0-RC1, I haven't looked to change ROM.
However, with CM-7.0.0-RC1 being released, its time to upgrade .
Can anyone please explain the steps needed to follow in order to go from CM-6.1.0-RC1 to CM-7.0.0-RC1 please?
I appreciate there is a lot of info in ali ba's dev thread [ [ROM] CyanogenMod experimental builds] however, there is approx 235 pages there, and the OP is a little lite.
Would it be possible to have guide here, as I presume many people will be wanting to follow the same upgrade path.
I am wondering how we can 'save' apps, [i.e. Angry Birds status, web browser installation, general settings/config,] during the upgrade... because I am guessing a full wipe is required and therefore a Nandroid backup won't really help...or will it?
Anyone that can help?

I'm also running CM6.1 rooted and I've tried upgrading by downloading Rom manager and then booting into recovery, doing a factory reset/wipe data/wipe cache/wipe dalvik cache - and then flashing the CM7 RC1 zip but I get a boot loop every time.
I've tried removing the SD card and Sim card but same error appears.
Actually it's weird because I've been getting a boot loop with every firmware I've tried to flash except for CM6.1.
Luckily I did a Nandroid backup...

First question should be:
Do we need to wipe when upgrading from CM6.1?
If we need wipe, I suggest you to:
- do a nandroid backup
- backup all apps with titanium backup
- wipe + flash 7.0 RC1
- download and install gapps
- restore apps with titanium backup
If no wipe required:
- do a nandroid backup
- flash 7.0 RC1
Question: does UOT kitchen (for circle mod battery) works with 7.0?

Issues?
Experience issues? Please provide the following info:
If the device was hard reboot, please provide the file "/proc/last_kmsg".
If the device was soft reboot or is "bootlooping", please run a logcat and provide the full ourput.
Please use Pastebin when possible

Yep, true.
Anyone?

Upgrading from earlier version of CyanogenMod 7?
* Perform a NANDroid backup of your current ROM.
* Flash CyanogenMod (your Google Apps will be backed up & restored automatically)

So no, you do not need to wipe before upgrading,
The backup is just for security reasons. You never know what could go wrong, so it's good to have a backup in place.
Just flash the new CM 7 and you should be good to go.

^ Mastacheata - thats if you're upgrading from earlier version of CyanogenMod 7
That question we are asking here is what if you're upgrading from CM6.1.

Oh I'm sorry, I misread that the whole time.
Gonna try it now and report back in a few minutes.

I've not gone 6.1 -> 7rc directly, but I did go from 6.1 to a 7 nightly build a couple weeks ago without wiping and I don't seem to have any problems (except GPS not working).

I'm thinking I may just do a full on Titanium backup, full wipe, then go for CM7.0RC1.

GPS not working in CM7.0 RC1 ??
Do we even have a list of things not working in CM7.0RC1? Again, the OP in the dev thread is a little lite with respect to 'known issue' and similar.

My test was unsuccessful.
I was neither able to install directly over 6.1 nor with prior wipe.
My phone would always end up in a boot loop.
Logcat did tell some Exceptions for unknown permissions.
Detailed explanation will follow in the developer thread.

i accidentally flashed cm7 build 0 over cm6.1 stable before. was able to boot but my phone was laggy & some features were broken, as far as i can remember. so i guess the best path is:
TI backup
complete wipe
flash cm7
TI restore
cliche by now, i know. but it never fails...

As we start the RC phase of CM7, many of you are now taking the leap from CM6 stable to the new RC's.
Some of you may be able to get away with doing this without a wipe; however, most of you will not be that lucky.
Differences in the rom, files system, and even Google Addons will likely throw most of you into boot loops.
Therefore, here is my recommended upgrade path:
1) Nandroid backup your current rom
2) Update your recovery to the latest available (CWR is my choice)
3) Format system via recovery
4) Wipe/Factory reset
5) Flash CM7 then Google addon 1/20
If any of you have data that you must absolutely save, then and only then should you use Titanium backup (or other backup apps) to restore your data. Please be sure not to restore any data to /system using these apps, as this will mostly likely corrupt your ROM and/or Market.

Perfect, I shoud've found that myself .
Now its just a question as to whether to go to CM7.0RC2 - lots of people still reporting bugs...

Newbie needs help/info

I have a T-Mo G2 and want to keep my Froyo image to reinstall later if I cannot get theGingerbread to work right. I want to make an image file that will restore the phone to exactly how it is now. I have tried all kinds of stuff, but am not able to make the "img" file so that I ca do a restore when booting...
Can someone point me to what I need to install to do this, and if possible some directions on what/how to create the "img" or restore file ?
I would be most appreciative, as I had to reverse everything from the OTA of Gingerbread, since too many apps didn't work, ESPECIALLY the GPS!
My current Froyo is a temp-root system.
Thank you all!
Aloha. .

I would do full root via the wiki, and then install 4EXT (the full one that's like $2) - it will keep your old stuff straight

Ditto on previous reply
Root your G2
Backup all your apps with using Titanium backup
Get Clockwork mod ROM manger or 4ext ( I prefer 4ext) and backup your stock rom. You can download new ROM CM7 for first ROM.
If you don't like the ROM you can restore your stock ROM with CWM or 4ext at anytime.

I have a theory that Ti Backup or any backing up of apps is a bad plan. I know you can do it no problem, and that it is a great time saver, but I have a strong feeling that this ultimately results in an unstable phone with mysterious force closes etc.
Even though it's a real pain, I think you are always better off reinstalling your apps from scratch after changing to a new ROM and wiping caches.

1. I have had zero problems with TB personally.
2. Without it your app data is gone.
3. Triple wipe, takes a few extra minutes and makes a world of a difference.
4. Do not restore system data!
5. Check md5 sums BEFORE doing anything!!!!
6. Make sure you have a recent nandroid backup and you'll be fine either way.
7. triple wipe before flashing anything including nandroids. Preferably with different wipes aka factory reset, superwipe+ ext4, then recovery wipe!
Just my 2 cents, it's saved my a$$ more then a few times...

Formatted /System, Help!

Hey all,
I was trying to get OTA2 installed while retaining my root and long story short I ended up formatting my /system in CWM thinking it would rebuild the factory image. Now of coarse my system won't boot. For some reason I am also unable to mount /sdcard. Is there anyway I could restore my system?
Thanks for any help!

restore \system of your CWM backup

I don't have a CWM backup . I know, a real bonehead move. If anyone could help me out with a clean CWM backup I'd be willing to compensate.
Edit: BTW I have a 16gb US version of the TPT.

Is it even possible to flash someone else's CWM backup?
Could I use the full image that Lenovo took down, found here?
I don't suppose there's an nvflash image for this device...

While I'm not sure, it might be possible to use that full image. Certainly worth a try. You might try asking on that forum, if you haven't already.

Yes, It is possible to restore from someone else's backup. I, in the past have copied my backups to my pc when they were too much and If i needed them, I just copied them back to external_sd/clockworkmod/backup/ and voila, it would appear for restoration in CWM.
I may be wrong, I do not believe that region should have any effect but to be safe (since you already made one mistake ) restore your US version with a US backup. I have a UK version and I would have uploaded a backup for you if you couldn't find a US one but unfortunately, my tablet is at the lenovo repair centre, being treated for the dreaded micro usb port failure. Hope someone here can help with a backup.

Thanks for the advice!
I downloaded that full image, but I could not get it to flash in the traditional sense. I extracted it and copied the system directory to my system partition and the tablet actually boots now. However, wifi does not work, whenever I press any of the menu keys a red frame flashes around the screen, and I cannot go to the About section of the settings to try to download updates or anything, it just crashes. I am also unable to update to OTA1 via zip in CWM, it gives me:
Code:
assert failed: file_getprop("/system/build.prop", "ro.buildfingerprint") == "Lenovo/ThinkPadTablet/Indigo:3.1/ThinkPadTablet_A310_02/0024_0065_US:user/releasekeys" || file_getprop("/system/build.prop","ro.build.fingerprint") == "Lenovo/ThinkPadTablet/Indigo:3.1/ThinkPadTablet_A310_02/0037_0075_US:user/release-keys"

Since you still need a lot of help anyway why don't you try manually installing all of the updates up to OTA 0076. You have to have all the updates before it flashed first. Link here:
http://download.lenovo.com/slates/think/tablet1

The nandroid backup would have to be of a factory restore, correct? Otherwise, all accounts/settings, etc would be within the backup as well.
I wasn't planning on doing a factory restore any time soon, but if the CM9 ICS port releases is soon, I can make one then as I have the same model and region as you.
I'm just really busy at the moment due to school and I rely on my tablet for school!

That would be the only safe way to let someone have a backup.

toenail_flicker, Thanks for the suggestion, I'll start from the top of the list and work my way down.
obscure.detour, being a student also, I completely understand. Luckily I just bought a Livescribe pen to offset my need for my TPT for the moment .
In the mean time, in case anyone else would be willing, you could also take a backup of your current system, do a factory restore, take a backup of the clean rom, and than restore your original image.
Thanks!

LOL You make it sound easy, but for a CWM noob it's a dicey thing. Never restored anything. Perhaps someone with more confidence in CWM than me can pull it off for you.

I know letting someone have a backup that contains personal info my be tricky, but if you've got time (couple of hours) on your hands you can backup your current system, do a factory reset, and since a factory reset only affects data, it wont wipe your root or CWM. you can then make a CWM backup of the newly reset rom, copy it off the sd card and restore your earlier system which you backed up.
This would save the OP having to start installing the OTA updates one by one.
Like I said, my tablet is away for repairs, otherwise I would have helped him. Or, maybe that's a good thing cos its certain that my tablet's main board will be changed, thus its going to be a fresh android installation on it. when I receive it in a couple of days, if you're still in need, I'll try to reroot and install CWM so I can send you a backup.

Much appreciated darkhandsome18! Installing the OTA's failed . It looks like the image I found is actually a test build. Even the earliest patches do not recognize it as a viable base to install on.

Did you ever get someone's backup? If not I can make one for you today. I am on OTA2 though, were you updated before you wiped system?

Here is a CWM backup from my 32GB US TpT.
Extract the file onto your external sd card in the folder /clockworkmod/backup/
Reboot into CWR
Select Restore Backup and select my backup (You can use advanced backup to restore individual parts or just the normal restore to restore everything, which will be factory reset US OTA2 with root)
Hopefully everything will work properly and you will never format your system partition without a nandroid backup again.
I have it on my Dropbox for now but will delete it in a couple of days because it takes up a lot of space. Let me know once you have downloaded it.
If you don't have a Dropbox account then sign up here and we'll both get an extra 250MB of storage space.

jhankinson, thanks! I was not on OTA2, would that be a problem? Also, I'm having issues backing up my current setup, I got ICS running. CWR gives me "Error while backing up boot image". Any ideas?
I'd like to backup my current (semi-working) setup before attempting to restore yours. Thanks again for uploading that!

I finally got it to work by remounting my sdcard in rw using ADB in clockwork recovery. That backup seems to have worked flawlessly jhankinson, I can't thank you enough!

This is great news! I knew I couldn't help you, but so glad GodfatherIP was able to help you. He helped me a great deal, too, recently.

[Q] From custom to stock again

So I haven't really used any custom ROMs due to the huge work needed after flashing one, I have too many apps installed and save games that I don't wish to lose.
Well I've decided to check out a few of the ROMs today and see which one I will like best, but I would first like to ask how I would back up my stock ROM is the first place. Now as far as I know you can do a nandroid backup using CWM and so I did that, it made a backup of my stock ROM along with data files off all the apps.
Now let's say I've been with this custom ROM for a few weeks and I'm sick of it, and I would like to return to the stock one. Can I restore stock by flashing CWM again, going to the backup menu and choose restore and then browse to the backup I made? Will it restore my stock ROM + data without problems?
Another thing I'm curious to know is, what's the best way to backup all of my apps along with their save games so that I can restore them to the custom ROM once I've flashed it? I've read about Titanium Backup but I do not see a "Select all" option, backup one after another would be a pain.
I hope I didnt confuse anyone with all these questions.

Use batch operation in TBackup
It allows u to backup n restore all apps+data
You can restore ur backup
sent using repencis 3.5 wid a2sd

Stupid me, how could I have not noticed that option. Thanks I have just started backing everything up, I suppose the correct option is "Backup all user apps + system data"?
As for the stock ROM backup, will it work as I said? I've read that CWM has bugs when it comes to restoring such nandroid backups. Also do I need to wipe cache and data before I can restore my stock nandroid backup?

1) Yes, its the correct option. It even backups save games and the entire data
2) It doesnt matter if you wipe data or not. But its fine if you dont do that. I dont wipe data at every nandroid restore and had no problems. Either way its the same, no need to worry about this. CWM backups wont restore or give some problems only when you restore a backup with different kernel. For restoring to work perfectly , the present kernel(before restore) and to be restored kernel must be the same.

Great, thank you.
For now I have transfered all the files from my TitaniumBackup folder to my computer. I am planning on transferring them back to my SD card once the ROM flashing is complete. After I put the TitaniumBackup folder on my SD card, I install Titanium Backup again and it will read the backups right? Then all I do is choose the option to restore them all and it will work with no problems?
Sorry again for too much questions but I always like to be on the safe side when doing such things, :angel: I crapped my pants when I ended up with a bootloop on my old phone :laugh:

[Q] Different backups, superusers, and flashing kernels

Hi all,
I have learned a lot about Android customization in the last week since my Nexus 4 finally arrived at my door, and I have become reasonably comfortable with the processes of flashing ROMs/kernels, and backing up my phone to make sure I have something stable to return to if something happens to go wrong. However, I am still dealing with a few points of confusion that I was hoping someone could clarify for me:
1. I have CWM installed on my phone and I can use it to backup/restore images of my phone for safety. However, I have heard about other methods like Nandroid, Carbon/Helium, and Titanium Backup while browsing the forums, and have tried them only to become confused as to how they are different from using CWM backup. Could someone please explain this to me and clarify which is the best for keeping a backup of my phone stored on my computer?
2. I have noticed that when I "wipe date/factory reset" in CWM, not everything on my phone is wiped. There are still plenty of files left over from previous ROM installs when I browse my phone with Android File Transfer, and obviously the .zip files you need to flash new ROM's/kernels are left too. What exactly is deleted when do a CWM factory reset?
3. Is it necessary to wipe everything when installing a custom kernel? I have CyanogenMod 10.2 installed because it is quick and relatively bloat-free, but allows for enough customization that I can make the my phone feel the way I want it to. I want to give Matr1x/Hells-core a try, but I am tired of factory reseting everything when install a new kernel. Can I get away with just wiping Cache/Dalvik and flashing the new kernels? If not, what is the best way to avoid losing app data between ROM and kernel flashes?
4. What is the difference between the default Android superuser, CWM superuser, and SuperSU? They all seem like the same thing and it makes me nervous installing different ones.
Any information you guys can offer would be great. Thank you so much for your time !

A backup in CWM is the same as a nandroid backup. It basically take a "snapshot" of your ROM and restore it exactly as it was when backing up.
Titanium Backup is an app that backup your apps and app's data. It's recommend you only restore user's apps and data. Let Google restore any system app's data.
2. I have noticed that when I "wipe date/factory reset" in CWM, not everything on my phone is wiped. There are still plenty of files left over from previous ROM installs when I browse my phone with Android File Transfer, and obviously the .zip files you need to flash new ROM's/kernels are left too. What exactly is deleted when do a CWM factory reset?
Wiping data/factory reset only wipe the data. Wiping system will wipe your ROM (system partition) Of course you don't want to wipe all the files such as the ROM you're going to flash.
There's an option to format internal sd, that will wipe EVERYTHING so unless you know how to ADB push files or sideload a ROM, DO NOT touch that.
3. Is it necessary to wipe everything when installing a custom kernel? I have CyanogenMod 10.2 installed because it is quick and relatively bloat-free, but allows for enough customization that I can make the my phone feel the way I want it to.

If not, what is the best way to avoid losing app data between ROM and kernel flashes?
No, just flash kernel. Some recommend wipe cache and dalvik cache after kernel flash before reboot.
4. What is the difference between the default Android superuser, CWM superuser, and SuperSU? They all seem like the same thing and it makes me nervous installing different ones.
Different app that does the same thing. Usually go with what is recommend by the ROM's dev. I ususally just leave what's included with the ROM.
Any information you guys can offer would be great. Thank you so much for your time !
