[Q] Installing MIUI on CM7

So, I am using CM7 on my i9000 and I want to simply try the MIUI.
I have just wanted to make a nandroid backup, install MIUI zip and then restore back to CM7
Will it work, or MIUI uses the custom Kernel?

Just do a data wipe and flash Miui via cwm.
To go back, wipe data again, install the new cm7 nightly, then restore your nandroid.

But doesn't nandroid backup EVERYTHING, including the rom itself? So, shouldn't I restore, and then update the Nightly?

Can't flash a ROM, or restoring a Nandroid

Hello,
I can't flash any ROM. I have the ClockWorkMod recovery. When Flashing a ROM, for example Cyanogenmod, it flashes it in 10 secons, and when I reboot it gets stuck on the lg splash. When trying to restore my anandroid backup witch I made with the same CWM 4.0.0.5, I get an error: Can't mount /system!
What can i do? Do I need making partitions? Are there HBOOTS in lg optimus 2x?
Thanks

update cmw version to 5... that should fix your problem

Really thanks for your reply, but my problem is that i can't even flash a ROM or restoring my own backup I made. How can i update it?? Thanks very very much!

Flash ext4 converter from the recovery, and then flash the rom http://forum.xda-developers.com/showthread.php?t=1037751
And I am assuming the backup you are trying to restore is from a stock rom, then flash backtoext3 from recovery and then restore.
Both files are available from the same thread.

And also don't forget to update CWM to v5, install rom manager from market and flash the latest recovery

Ok, so really really thanks for your answer. the backup is from the original LG ROM...does that change something??
Thanks!

Yup, the stock rom is ext3 while cm7 is ext4. Its just two different filesystems.
Sent from my Optimus 2X using xda premium

So, the steps I have to follow are:
1. Flash ext4 converter
2. Flash a new ROM
3. Flash CWM 5.x.x.x with Rom Manager
And, whenever I want to restore my backup, I need to flash before the backtoext3 patch.
Is that right? Sorry for being so stupid!

You need to first wipe data, cache & go to advanced and wipe dalvik cache.
You need to flash backtoext3 only if the backup you are trying restore is from a stock rom or a rom which is using ext3 filesystem.
Sent from my Optimus 2X using xda premium

Ok, so finally I have successfully restored my backup. I flashed the ext3 patch and done. Now I have installed CWM 5.0.1.6 Is this recovery ok?
Now, before doing anything, I want to know what steps do I have to follow to install a ROM.
Even having this new recovery, do I have to flash the 4ext flasheable to install roms like Cyanogen, Thanatos, Miui...?
Thanks!

I am having v5.0.2.0, Check the rom manager if there is an update if not than that recovery should be fine.
To install a rom you need to wipe data, cache and dalvik cache. After that just flash the rom.
You don't need to flash ext4 zip, because ext4 based roms will automatically convert the system to ext4.

Thanks, normally, how long does it take to flash a Cyanogenmod nightly? It took me 20s...is that normal??

Just flashed CyanogenMod...AND WORKING!!! So good...Now...The best ROM for you? Thanks!

I think this thread should help you. An all in on place.
- Make sure that you read and understand complete instruction on the particular ROM developer's thread. Pay attention to the possible problems and solutions.
- Nandroid backup. Backup other user data and applications
- Make sure that you wipe/format the /system partition before flashing a ROM. I was not doing this untill recently. Ever since I started formatting /system partion, not getting SODs and BSODs like before
- The CWM you are using now is bit outdated. Look for the latest version - I think it is cwm-5.0.2.7-R2. Check out this link.

brothers and sister..

can i update my p1000 into 4.0.4 ics CM9 nightly build.im using overcome 7 no wipe now i have a CMW recovery.can i flash the cm9 nightly using nowipe instead of using GBstock? pls tell me i want to upgrade my tab..

No. You will lose all your data.
Backup using Titanium Backup and then flash cm9 and gapps.
In fact, you better wipe everything.
Sent from my GT-P1000 using XDA

but can i use overcome 7 no wipe after i backup all of may data

I have replied to you previously in detailed steps. Overcome wipe or no wipe is the same stuff.
Yes. No need to restock. Backup and copy your internal SD content to somewhere safe, in the PC or something.
Boot to cwm and do all wipes.
Then flash cm9 then gapps.
Sent from my GT-P1000 using XDA

what do you mean about gapps im confusing about gapps? sory im noob about using cmw...sorry

A collection of Google apps, such as Play store , Google finance, etc.
Just download it and put in sdcard

Sent from my GT-P1000 using XDA

Gapps stand for google apps gmail, play store, etc when you flash cm9, the first thing you notice will be there is no gmail or play store if you do not flash the gapps

overcome 7 is on ext4 file system, therefore you can flash mtd file system ICS roms without restocking. when installing ICS ROM through flashing and loops occur, just press the volume up button until you are back on the cmw menu,then flash ICS ROM again.

brother tnxs for helping me....god bless u

perhaps hitting the thanks button will do!
oh and do keep me posted wheter you've flashed it successfully.

Brother do you a theme for. Nightly build cm9 ics..?

[Q] Nandroid Restore CM10 --> ICS

Hi All,
Is it OK or Possible to Nandroid restore my old Stock ICS ROM from CM10 CWM ROM(Recovery) ?
Thanks.

Yes. Done it many times.

You're on a safe kernel, so it will be fine, be aware when back on ics if on stock kernel you need to be careful or install safe kernel.
Sent from my GT-N7000 using xda premium

yeah I guess if he made a nandroid backup of a stock rom.. 99% it has a safe kernel in it.

Thanks for the help guys ... :highfive:
& I hope the other way is also OK (Restore CM10 Nand backup from ICS CWM recovery) ?

ya

Sorry if I am asking/saying something wrong..will the Nandroid restore work if currently using a different kernel than the backed up one? Read somewhere that current kernel & backed up kernel should be the same for the restore to happen properly..

no.. u can restore the nandroid made on any kernel. just that when the nandroid restore completes the kernel will be that inlcuded in the nandroid

Thanks guys :good:

You may well face bootloop after restore, just clear cache and dalvik from recovery, should clear it fine.
Sent from my GT-N7000 using xda premium

clear cache and dalvik from recovery + format /system
then restore from recovery
(recomended) restore using recovery & kernel you using for backup
works great for me

[Q] how to downgrade from CM7.1 to stock rom 2.3.4?

Hi,
I used CWM to backup stock rom(2.3.4), then I used CWM to try CM7.1 nightly. Now, I would like to go back to 2.3.4. I restored the backup rom. The step i took was:
full wipe
format /system
install http://nigella.modaco.com/files/r2-backtoext3-2x-unsigned.zip
restore backup rom
reboot
After that, I rebooted. There is bootloop. Just wonder if anyone know why and how to solve this? thanks in advance!

When you get back to stock lg from cm you must format all ext3 before restoring. Search for Dr4go tools.

Thanks for your reply.
I tried to use r2-backtoext3-2x-unsigned.zip to restore it.
Can you tell me the correct procedure?
1. enter CWM mode.
2. install r2-backtoext3-2x-unsigned.zip
3. full wipe
4. format /system (i think i dont need this step, right??)
5. restore 2.3.4 backup
6. reboot
Is this correct?
Maybe i should try to use Dr4go instead ofr2- backtoext3-2x-unsigned? thanks

Very simple:
1. Cwm install ext3 zip file from Dr4go
2. Cwm restore your stock backup
3. Restart

Get the "old" file which means for the old bootloader.

thanks a lot for your detail reply, a bit busy this week, I will test it in this weekend.
In fact, I dont get the idea of old and new bootloader. I am confused if this refers to different file system ext3 vs ext4?
thanks

The bootloader is the first program which starts the phone (or any computer), ext3 and ext4 are different data mgmt systems.
Your case is old bootloader, the new bootloader was introduced by LG with ICS roms. But this is another story.
