[Q] How do you Remove CyanogenMod7 nightly. - LG Optimus 2x

Hi guys, first of all I'm a total noob.. first android phone first time rooting, and installing a mod... I should of done more research before installing the CyanogenMod on my phone because now its all buggy and i feel it worked better before. If some one can help me get my phone back to 2.2 that would great.
-Do i fist install a stock rom from http://forum.xda-developers.com/showthread.php?p=12890619#post12890619
-I'm located in the philippines and I dont see any rom for my country all i remember is that I had v10b.
-im not sure if my phone is using ext3/or ext4 but i think its ext4 since im using cyanogenmod. do i need to set it back to ext3 first?
I backed up my phone using nvflash and nandflash.
-first thing i tried before was: wipe data/factory rest, wipe cache partition, wipe dalvik cache and then hit restore. afterwards i booted my phone and it was stuck at the loading bar. so tried the same steps again but nothing so i loaded cm7 zip again my my phone booted up. how do i take this off can someone help please.

it will restore your phone back to stock

after nvflashing v10b back on your phone, you can restore your backup if you like to. root and clockworkmod must be installed first though. To install clockworkmod you can also download the clockworkmod recovery img and replace recovery.img in the nvflash files. this will install cwm directly and you don't need to root your device.
You don't need to convert back to ext3. I'm not even sure if cm7 uses ext4...
The reason why you are not able to restore your backup is because of some bug in cwm with restoring boot.img I think..

[Q] Plz help! Screwd up my Captivate while re-installing Latest CM7 nightly Build181

Help Needed.Looks like i screwed by Samsung Captivate.
here is what i did :
My captivate was running cyanogen mod 7 (nightly build cm_captivatemtd_full-181)
I wanted to re-install CM7 and did the following:
1)Phone already had the copy of the same build in root directory which i used for cm7 install for the first time
2)I kept the phone in download mode and Used ODIN to flash the Kernel.It went through successfully.
3)I used the three button technique and tried to install the Build which has failed with 'assert failed:getprop (" some blah blah) saying finally installation aborted.
Not sure if i should have recopied the build to the phone instead of using the same existing build in the phone
4)Though the installation failed...my phone is not booting up and when i reboot.. the phone is hung with a message 'galaxy S scg-i897 Samsung' and doesnt boot up.
Please help on how to recover my phone to a normal state.
4)
This should be in CM7 thread. Did you try going back in to recovery? Try to get in recovery and factory reset+wipe cache and wipe dalvik and reflash?
I did all the steps you have mentioned in recovery . May i please know what do you mean by reflash?
you mean again i have flash kernal and install CM7 ?
Also as you know the i cannot copy any build to the phone as phone is booting up . Do u mean i have to use fresh build instead of the one which is there since my first cm7 install..
please suggest.Thanks for you reply.
If you can get in to cwm and you have a cm7 rom in your sd card, then you can attempt to reflash the rom. IF that's not possible ODIN back to a "stock" and start all over.
^Or...If you can get to cwm...you can mount the sdcard, in mounts and storages, and transfer what the hell ever you want over from your PC to your phone. Like a fresh download of cm7 for example...
sorry i know i am taking your time .
i am very new to these techincal words..
1)can you please help me how i can go into cwm ?
2)How to ODIN back to 'Stock'?
Thanks.

CWM= ClockWorkMod its the modified recovery used to do a whole bunch of things one being flashing roms.
If you don't know how to use ODIN then you shouldn't be messing with AOSP's or flashing for that matter.
Read First thread
Captivatte Directory thread <- lots of guides there.
How to Gingerbread thread
All of these are stickied and you should understand most of them to flash "safely"

LG optimus 2x bootloop after failed cyanogen mod

Hello!
Today, i decided to install cyanogemmod on my 2x. So i downloaded ROM manager and downloaded cyanogenmod. everything went fine until i was going to boot for the first time. I got into a bootloop. so i tried taking out the battery and all that stuff but it still would't work. So i tried to recover the phone. I recovered it to a month old backup (I could not find the one i made in ROM manager before i installed cyanogenmod) The recovery went fine. But, when i rebooted it got into a loop on the lg logo! (the one without the loading bar) it would just load the lg logo, be there for like 10sec, then it would do the same. I tried recovering one more time, but it didn't work. The same thing happend. What should i do? :S Should i wipe data/factory reset?
EDIT: My phone was on android 2.3.4 before i download cyanogenmod.
BTW before i installed cyanogenmod, i forgot to clear cache and data. I was in a hurry so i did't notice the screen popping up, I automatically pressed "ok" without selecting anything.
Thanks for the help

Different partitions... Look for something called backtoext3 in the dev section (or somewhere else) The problem is that when you flash a custom rom like CM you convert your filesystem to EXT4, while stock is EXT3.
So basically what you have to do is:
1) Reboot into recovery
2) Wipe everything
3) Flash Backtoext3 zip
4) Restore Nandroid.
This should work. this will take you back to stock.
So i have to restart the phone, Choose wipe data/factory reset, then flash backtoext3 (how do i do it? lol) then restore nandroid (the backup i just tried to restore twice?)

Yes
Flashing backtoext3 is just flashing the zip file you put on the sd card. (and then install zip from SD ) an then restore your nandroid stock backup and you're back on stock.
But you said you wanted to try CM right? In that case, wipe everything (factory reset/data + cache + dalvik) and then flash the CM7 rom and you have CM! Don't worry about backtoext3, your partitions are already on EXT4, because of your prior CM flash.
Ohh! Thanks Can you send the files for cm (2.3.4)? I've found some, but im not sure if my phone is compitable with them :S im really afraid to mess something up again
My. Signature. (CM7 temasek's KANG = the best CM7 at the moment )
I did everything and i got into a bootloop at the skating andriod screen again
OK, restored my phone back... Now it wont connect to the network and the battery has a question mark inside it. It also says the battery level is 999% heelp
Nvm, got my phone back to normal still dont understand why cm wont work...
You need cwm5 to flash cm.
I have a G2x, which is basically the same phone. But anyway, I would recommend nvflashing CWM and not getting it from ROM Manager.
CWM 5.0.2.0 will do just fine, but it is indeed old...
Anyway, are you sure you waited long enough on the CM boot screen? The first boot might take a couple of minutes. (4 or 5)

Major help please

Yes - that happened to me also. My first "bad" experience with flashing
from what i read CM7 running ext4, stock runing ext3 right?
so now i'm back with stock running froyo, i still have my backup files on with sd card. Do i root and install rom manager then install Back2Ext3, and final running restore? will this restore back to my original state since i backup using cwm to backup.
thank guy
yes, cm7 uses ext4 system mount. i just use a zip file which i flash from recovery if i need to get back to ext3.
here it is btw if you are on stock froyo and want to restore stock gingerbread (if i understood you right) you dont need to use back to ext3 again, just restore your back up.

Restore stock backup from CM needs to flash an ext4-backto-ext3 zip with cwm, what a pity you overwrite cwm with stock recovery.
Now you should try to rescue your phone with SmartFlash, finally consider nvflash method.

Download a Stock Rom from sammobile.com or one of the prerooted Roms (I always use a GB LC1 from bodivas for this) and install it with the PC version of Odin.
tried that, Odin stops at "NAND write start!!"
AW: Softbrick N7000 Need Help
What Rom did you have and what did you do before this happened?
Sent from my GT-N7000 using xda premium
Now I used a regular Android 4.0.4. ROM
Before that I tried with a 2.3.1 ROM. This is probably the reason for the trouble, isn´t it?

And what Rom exactly?
And what did you do before stopping at boot logo?

I was already downloading the 4.0.4. ROM. Because I read somewhere it´s not possible to go from ICS to Gingerbread.
The download just finished right after you answered and I tried. I am 100% sure i got the right ROM.
Before getting all these Problems, I wanted to get a CustomROM on my phone. Android 4.0.4 was installed at that point of time.
I rooted my phone and did a backup with CWM. Then i chose wipe data, while doing that I started to charge my phone (I don´t know if that matters). I didn´t see what happen exactly because i wasn´t looking at my phone all the time, but when i looked at it again there was only the charging sign shown. Then I tried to get into recoverymode again. This wouldn´t work. I tried to flash CWM with Odin which worked after some time. Then I tried to Wipe data and cache again. wipe data wouldn´t work. Wipe cache worked. I tried to install the backup. After waiting for more then 1 hour it looked like nothing happend and the installation was stuck. But the regular recovery of Android was installed.
Because flashing a ROM through CWM wouldn´t work, I tried to flash it through Odin. First time I tried with a Gingerbread Version. I was thinking, I don´t care which version as long as it works and try again to install a CustomROM from there on. Odin stopped at NAND Write Start!!. Tried it with the ICS Stock version. Same thing.
This is where I am at now
Did you use cwm.zip?
To use with Odin? No
When I started it from the regular Android Recoverymode? Yes
Don´t you think this might be exactly the problem I have?

[Q] Help me understand whats going on.

okay, first of all i will say that im sorry if what im writing is full on faulty language. enlgish isnt my best. aaaanuslut i got my brothers old gt n7000 with a broken touchpad and screen for free. i repaired that with 160€ and my brother said that the phone was rooted. i found out he had allso overclocked the device. But after a few restarts to the phone it just said something what i think was in spanish or something "bla bla bla dos sistema". After that came not your old samsung logo, but purple blueish circles just circling. Ant thats it, it would not start. So i read about bricked devices, and as much as i understood i had a soft brick. so i was looking aroun the forum for some easy fixes becasue im totally stranger to this kind of hacking. i finaly found this http://www.youtube.com/watch?v=F97qo1moAR4 and i downloaded custom jb N7000XXLSZ_N7000OPSLS6_N7000XXLSO_HOME.tar. it did work but again after i tried to restart the phone it was stuck.
So since i dont want any custom stuff i think to my self why not stock rom. so i found this http://forum.xda-developers.com/showthread.php?t=1424997. But since i dont like JB as much as ICS i will try ICS. Her is the question: i allready did the factory reset and cache wipe but this instruction says not to FROM ICS.
Warning :
Don't wipe anything from stock ICS recovery
Don't factory reset/Hard reset on stock ICS.
Don't flash any Wipe version of ICS ROM
Does that mean that i have allready gone wrong or does that mean that you have to have ICS on youre phone and then you cant do any of those things? its really confusing and i dont want to fk up my phone.

flash via recovery phils kernel, (a newer one) reboot in recovery and perform the wipe for new rom option.
That should clean your device good.
Then flash what you want. After that download an emmc check app and check. Shouldnt be needed, but its nice to check.

Allright, thankyou, since i am new to all this stuff i will try to locate a tutorial. i dont have any idea for instance, what is recovery phils kernel.
at own risk, here http://forum.xda-developers.com/showthread.php?t=1901191. Download zip, keep zipped and put on external sd. Reboot recovery and flash via install from sd option.
Since we are going to wipe latest version will do fine. However if you plan to reflash the original Samsung rom one that is same or likewise version is best to quickly root after flashing rom, so you can flash speedmod kernel (better battery life) after. Find in original dev thread of this forum.
Remember, via factory format on phills kernel recovery(reboot in recovery) you have the option to do a wipe for new rom.
Otherwise on Phills kernel recovery do factory, cache wipe. In advanced dalvik cache, in mounts all(warning take out external sd before so you dont wipe that)
Then your phone is clean, you shouldnt have to wipe efs anyway, so dont tick that option ever in pc odin when flashing rom with odin.
This is the cleanest way to get rid of All leftovers and generally the way to go before flashing any new rom. However risk of loosing photos and whatever you have not backed up. In general backing up is bad as old files/db/etc are put back (risk of unforeseen stuff happening) Check one of my 5 threads for what backups there are. Via my profile you find them
Enjoy!

Okay, im thankful for all this information, useful stuff, got the PhilZ-cwm6-XXLT6-XSA-5.06.1-signed.zip.
let us know how it went, ok?
OOOKAY! so i finaly did what baz77 described. and rooted with another phils kernel witch i chose after my downloaded rom. Did root it, and after powering down and waiting about 3-5 sec. i started it, and it worked, no more getting stuck on gt n7000 screen and so on. and i also downloaded emmc check app, but unfortunatley it said. Brick bug: YES. Insane Chip.
sorry for double post, how do i delete? all i can do is use edit/delete button but it only edits the post, how can i delte it?
You cant but thats ok.
all n7000 have the brickbug to my knowledge, the test should state if the bug has been triggered, if not then super, if it has, best to secure the broken emmc sectors. Tricky.
I think having it clean now should eliminate earlier issues Enjoy your n7000
Thank you, i will, lately my n7000 has been rebooting randomly, any fix or know issue why this occures?

not sure how that is happening. Maybe a logcat (logfiles) shows whats happening when it happens. Could be app. Maybe rom issue. Method of elimination counts here.
On safe kernel, try dalvik cache, cache wipes and fix permissions in recovery, reboot and check if reoccurs.
Otherwise, updated versions, clean install I would recommend.
You can check also before with that emmc app if there are bad sectors. I dont expect it but you never know
Okay, its been a long time since i did that stuff. And it worked allirght. i got my phone working and rooted. Great stuff here
Sorry for updating old topic. Since people who have helped me with my phone allready are familiar with my case. I was wisiting a friend of mine in england and after i returned home my phone is f**ked. Everything works okay, but when i turn on mobile data or wifi it instantly freezes. Takes about 15-20 sec. and then phone does an automatic restart which restarting gets into boot loop. I have to hold down bower button to reboot again. When it asks me for sim unlock code, i have to be quick when im inserting it because i need to turn off mobiledata/wifi as soon as ia get my phone running again, otherwise it will freeze and crash again. Can it be somekind of virus or something? Is it most likely that i have to again format and install philz kernel and all that stuff? Thanks in advance.
that would be the best way to start..IMO
I really dont have the time or opportunity to format and reflash, but i guess its really difficult, near imbossible to tell whats wrong with my samsung. Bust still, any other suggestions?
