[TRICK] restore after testing CM7 ( switching ROMs )

Hey guys I noticed people having problems restoring a back-up after testing CM 7
So here it is; switching ROMs with NO data loss
The deal is CM7 has is own kernel and there fore his own recovery.
Back ups made in another kernel ( and this means other CWM ) can not get restored with CM7 kernel.
And of course the other way around.
what you can do to easy test CM 7 and get back
- make nandroid backup with your own CWM, probarbly Doom kernel
- flash and test CM 7
- take the ''boot.img'' from the download of your kernel you had before testing CM7
- place it in your fastboot folder
- connect phone in fastboot
- in fastboot issue the command ''fastboot boot boot.img''
- the phone wil reboot, now dont let it boot but enter recovery
- you are now in the same recovery where you made your back up, so just restore it.
all done
---------- Post added at 05:14 PM ---------- Previous post was at 05:12 PM ----------
you can also do this the other way around :
[ UNTESTED ]
- make nandroid backup with CWM in CM7 kernel
- restore stock as stated above
- take the ''boot.img'' from the download CM7
- place it in your fastboot folder
- connect phone in fastboot
- in fastboot issue the command ''fastboot boot boot.img''
- the phone wil reboot, now dont let it boot, but enter recovery
- you are now in the CM7 recovery so you can restore CM7 back up and go back to testing

hi can u tell me exactly wht are the issues restoring backups when using latest CWM 4.0.1.5?

thatt is not the back up used in CM7 and as far as I know you cant take a back up made with CWM 4.0.1.5 and restore it with CWM included in CM7 right ?
or is it already possible at the moment ( been away for a while )

thanks man if doom can ( no we know he can, if he wants to ) that will be great

Hmm, but where's the advantage? I don't get it, sorry
It saves about ~3 minutes of time because your just booting the image and not flashing?
Or do i miss something?

Well just means ya could restore data from your current rom on top of cm7 and have all your current setup wit no setting up

I dont think that that is going to work but it is worth a shot.
The advantage is : when it is done you can switch roms without the need of a PC ( and a bit faster and easier )

I think i read some where that the arc is missing some partition ,which allows u to flash kernels on the phone
So im not sure it will ever be possibe without fastboot
Edit:

we cant write to boot partition from recovery... so only way to flash custom kernels is via fastboot...

yes but if doomlord and CM7 use the same recovery than we wont have to change the boot.img right?
because you can restore your system from CM7 to stock without flashing boot.img
you just boot it and than restore after that the phone will reboot in boot.img that was already on the phone
not the one you booted this one time to get in CWM

As far as I no cm7 kernel will not work on stock rom and doomkernel will not work wit cm7 rom
So even if we get same cwm on both neither will boot others rom and you will still have to use fastboot to change kernels because kernels are not compatible with both
This is how I understand it to be ,im no expert tho
Can someone confirm this

yes u are partly correct...
CM7 kernel should also work on stock THOUGH some functions may/may not work...
my kernel MIGHT NOT work on CM7 as it requires a diff ramdisk... it will boot but some CM7 features/functions might be broken...

Thanx for clarifying
Is it a case that we will never flash kernels without fastboot or is it something that can be solved in later dev
Thanx again
Ps v10 is running v well for me

That thread is dead (at least for now). What's the point in linking it?

I've read good things about this OS. Sony has recently released a ROM for the Xperia E!
In my opinion the atrix development should be focused in building an ICS kernel :/

i hope that will work someday.

[q]aokp q & a

I figured I'd start a thread for this ROM.
My first question or bug report not sure which...
When turning on 2G networks only, it changes preferred networks to GSM only.
Makes sense.
Only problem is when coming out of 2g only mode, it changes the preferred network to wcdma not LTE.
There a way to change that or that just how its designed?
Thanks.

This thread will be obsolete once i get the official Q & A thread started. It will be kinda like the one i have for the sgs3 here http://forum.xda-developers.com/showthread.php?t=1781242. I'm already working on it.

In the mean time, may I ask if sdxc 64gb cards are supported in exfat? My stock rom had no problems with it but aokp won't mount it saying, "blank or unrecognized card."
Do I need to format to fat32?
TWRP still recognizes and reads files of of the card with no issues.

Thanks task.

Twrp still reads it because it's a 4.2.2 aosp problem (I'm pretty sure at least). I am curious if formatting the card would help but I doubt it b/c it didn't help on 4.2.2 on the s3. It's a minor inconvenience but personally I'm just glad to get TW off this thing. Thanks Task! I didn't think the first build would be really buggy or anything but I did expect some minor issues on the first build. Couldn't have been more wrong though, is so fast and stable it's not even funny.

Is there a way to Turn ON/OFF the Wireless Tethering function from the Power Menu, Desktop Shortcut or Notification Bar Icon?, thanks

No you won't lose them unless you delete them yourself. But you won't be able to use them unless you flash back to the recovery that they were made from.

If he needs a step by step video of how to install the ROM then I would suggest him to not flash anything to his device until he reads up on these things more. Otherwise I see him bricking his phone in the near future.

How is that even possible? The instructions are simple and slapped right in your face. 1, make sure you have OUDHS, 2, full wipe then flash. Couldn't possibly get any easier and if people can't figure that out then they should not be modding hardware :angel:

Easy as Pie to flash task roms it already has the kernel in it. it's full proof!

Does it takes some time for the Task650 ROM to fully leverage and use the battery to its maximun potential?, with the Stock TW ROM I was getting around 0.5[%/hr] battery usage/drainage with the phone fully idle, measured by BetterBatteryStats, right now I am getting around 3.5[%/hr] battery usage/drainage with Task650 AOKP ROM, comments are welcome, thanks
NOTE: I've been measuring Deep Sleep with CPU Spy and with BOTH ROMs Deep Sleep will be around 93% to 97%

[4.0.4 Rom] CyanogenMod 9 [Built From Source] - Alpha Stage - Flash with Caution

Hello! This is a CM9 I built from source some days ago using CM9 device & vendor tree made by Ivan/qiwu (big thanks to him for this)
This ROM is in really early stage.
IT CAN BRICK YOUR DEVICE !!! FLASH CAREFULLY !!! YOU HAVE BEEN WARNED !!!
What works:
I think everything works apart from camera !
I have tested this rom on my phone before uploading. When I rebooted in recovery through the reboot menu of the ROM my device was hard-bricked. That means I sent it to service in order to repair it!
In this rom I intergrated a fix for camera and also for recovery I think.
Still you are NOT encouraged to reboot into recovery from within the ROM unless you want to test how lucky you are.
You can flash this rom and tell me what other things may not work correctly and also try to make your own fixes for the problems mentioned above.
Flash via CWM 5.0.2.7
1) Wipe data/factory reset
2) Advanced-> Wipe Dalvik Cache
3) Instal from .zip in sdcard
Notes:
1)Installation will get a lot of time. No other rom took me so much ever. Just wait patiently and it will eventually end
2)If you have no baseband/imei=null try using the amss.mbn from gingerbread pinkscreen image folder -> aka the gingerbread baseband file
Download link: https://sourceforge.net/projects/moidroid/files/CM9_U8800Pro_Alpha.zip/download
AGAIN I'M NOT RESPONSIBLE FOR ANY DAMANGE TO YOUR DEVICE !!! NO ONE FORCED YOU TO FLASH THIS ROM !

Thank you Moihack! I can't believe how much Qiwu Huang has helped us... Good luck with this project

of course not. ivan also made device & vendor tree for cm9 for u8800pro
it isn't available at his github anymore , but the lewa os team (ioz9 at github) had made a fork
@ svteam : I didn't try any other cameras but I think you 'll get the same errors. Some libraries and maybe some bin files may need to be changed in order for camera to work.
@ rittik : thanks! hope you can fix the non-working camera or/& the recovery issue
be careful with the recovery fix though! it may brick your device.

[Q] Switching back and forth between nandroid backups

Is it ok to frequently switch between backed up nandroids? For example... switching between 2 different ROMS (CM10.1 and a TW Rom)?
Is this a totally safe practice?
Thanks

yes..that is the whole point of backups and restores
just make sure you wipe before it and not do dirty flashes

Is that even if your backups are for ROMs both on different versions of Android?

Make sure you back up the boot partition also since different versions of Android use different kernels. It would be wise to keep a zip file of the kernels on you sdcard so you can flash them easily if the phone doesn't boot up after a backup.

Search for "noobdev dual boot" on this forum. I believe it is a much more convenient solution than using backups and a lot of roms are supported

Which Kernels? How do I get a zip of them? excuse my ignorance but I've never really got involved with them so the above means nothing to me. Any useful links would be gratefully received!

The great thing about the dual boot is that you can switch between roms in a matter of 2 minutes (install excluded)
Typically I use it so I have my daily driver and one or two roms I want to give a try. Once I am happy with one of the try-outs I upgrade the primary.
Bottom line is the dual boot is very easy to work with, doesn't require (although it can be preferable to have one once every now and then) backups and allow for easy flashing of new roms without affecting your daily driver.
It damn well looks like you could use such convenience because if your ready to do what you listed above then I'd say you're likely to want to try new roms fairly often
