[Q] Rom Manager VS NvFlash

(beware, noob here )
So, I've decided to flash CM7 nightly #127 (which seems to be the latest build) to my O2X...
I am completely new to this, so I am going to follow this tutorial: http://wiki.cyanogenmod.com/wiki/LG_Optimus_2X:_Full_Update_Guide
As of now, I've successfully rooted my device using SuperOneClick (so much easier than the method described in CM tutorial), and I made some backups with Titanium Backup.
On the forums here I read you need to also use NVFlash... That it is better that Rom Manager.... But there is no mentions of it in the official CM tutorial... All I found was this http://forum.xda-developers.com/showthread.php?t=1054492 but I'm not sure of what it does, and if it is necessary to use it when flashing CM...
So, what should I do? I already installed ROM Manager and flashed the recovery thingy... All I need is a external sd card (which I going to get today) to make the Nandroid backup, copy the CM zip on it and Flash it...
Is this procedure risky? Do I absolutely need to do it with NVFlash? Is it ok to do this as I already set up Rom Manager?
Any help will be greatly appreciated!!!
Thanks!!

NVflash is not necessary, in fact not even needed. Just need the cm7 zip file which needs to be renamed to 'update.zip' and put it in the root of the sd card. I think it's possible to flash using the internal sd card but I'm not sure. Once you flash that, you should flash the gapps file using 'install zip from sd card' using clockworkmod. Both of these flashing methods using CWM. I didn't use ROM manager, I just booted into CWM recovery and then flashed it. ALWAYS make a full rom backup before flashing and you should be safe and yes it's very safe.

Nv-flash is only needed when you have to restore your phone from some thing close to a absolute brick (when you have flashed some thing wrong or done some thing really bad, and it don't start by any means). That's when nv-flash is used to restore it as an last option. When nothing else works then you use it.
The metod described in the update guide is more advanced and yea its a bit of pain. But at the same time you do gain some practice on things that might be needed to do later in case you have problem with your phones. Things that people here on this forum almost assume that you know how to do. Also it works on all current known firmware for LGO2X. At least follow the steps until you have the adb set up. It might save you the frustration when you sit there and have problem with the phone.
Flashing is easier and faster with the rom manager app. Just remember to move your backups from titanium to the external sd as well. You don't want to lose those backups, right?
Last but not least.
Welcome to the living hell of always flashing the latest firmwares =D
And constant hunt for the highest ver numbers!
PS: Its safe as long as you remember "BACKUP BACKUP BACKUP"

Thanks for the replies
I have now successfully flashed the latest CM nightly build !!! And it rocks !!! I can't believe how sluggish my phone was with the official firmware... It is just crazy...
I had a few issues though:
- When I flashed CM (after data/cache wipe / factory reset), I couldn't find anything on my external SD card... To access the CM zip, I had to navigate to the internal SD card, and there I had a "_ExternalSD" folder... a bit weird...
- I exported all my contacts' numbers on the SIM card before flashing, but CM did not find anything... Hopefully I had a backup on my desktop, and had to manually re create all contacts (good thing I don't have too many...)
- I flashed the latest google App from http://wiki.cyanogenmod.com/wiki/Latest_Version#Google_Apps but the Market is the old version (2.x)
Other than that, I am now a happy CM user... No way I go back to official LG bloatwares!!!

You can flash (with CWM recovery same procedure that you used to flash CM7) latest Market from here:http://www.mediafire.com/temasek (Go to Misc Folder)

Should I uninstall (somehow) my previous Google apps, or can I just flash the new version on top of the old?

I just saw that a new CyanogenMod nightly build has been released (#146) and I'm eager to update (from #127).
But I am wondering if I need to go through the whole process again (Nandroid backup, clear data/cache, wipe, flash CM, flash google apps)...
Or can I just go to recovery mode (from Rom manager) and flash the latest CM build??
Thanks in advance for your answer!!

NVFlash is used kinda like fastboot for our device (Cyanogen said so in the RC1 forum), a just in case scenario. As if in rom manager gives you an endless bootloop and you can't boot into recovery mode. You can use the NVFlash CWM or rom manager, I actually never use rom manager; I just uninstall it.
As far as the CM Wiki goes, I'm trying to change it to include NVFlash but the wiki people are a bit strict on what gets linked to what...

Yep, that's all you need to do.

[Q] sgs cwm recovery problem

hello .
i am using galaxy s i9000 , with stock ddjv9 , n speedmod kernel .
i flashed speedmod kernel n i was able to reboot into cwm recovery using 3 buttons .
then i installed rommanager from market but it was not recoznising the cwm recovery version , so i flashed cwm recovery again frm rom manager .
but when i select reboot into recovery or back up rom frm rom manager it reboots to stock 3e recovery , n doesnt perform any backup .
i can still boot into cwm recovery 2.5.1.2 using 3 buttons .
plzz help . i want to use rom manager to perform backup .

Forget from manager and you your recovery to perform a backup. It's called a nandroid back up, it saves your whole system in its current configuration.
You restore this backup if something goes wrong and you can't boot up to your home, but you can still use recovery. If you want to backup apps and stuff then use other means such as titanium backup. If you want specific backups then let me know and I will give you a list of what i use.
As far as I know rom manager does the same thing however automates it so you don't have to go to recovery and go through the selections. Another thing you may need to be aware of is if rom manager doesn't recognise your recovery, any backup you attempt to make may be corrupt and un usable. If you want to fix recovery you may need to reflash your kernal. Not just CWM. This should retain all data and settings.
Hop that helps

But i cant do back up frm cwm recovery too . Its reboots into 3e recovery n nothing happens .
I want to use rommanager to flash custom roms after making a backup .
So my main aim is to make cwm recovery working thru rom manager .
My rommangaer can detect cwm recovery . After i selected flash recovery frm rommanager. But cant reboot into it or do other functions.
Plz help. With steps to perform.

Thought you could get into this recovery??
Are you saying when you use the 3-button combo to get to this recovery it works, but then trying to make a backup does not work??

So what your saying is although rom manager detects it (recovery), it is useless as you cannot get into it to make a backup via rom manager
I suggest first go to manage apps and clear data for rom manager>>>open up rom manager>>>make a backup.
*CWM not detected?>>>flash via Rom manager>>>Backup...Remember because you are on stock your device is Galaxy S not Galaxy SMTD. As i believe MTD is for cyanogen based roms (I am 99% sure of this)
*If this still does not work, clear data again>>>do not open Rom manager but turn off phone>>>go to recovery (via 3-button combo)>>>Backup/restore>>>backup
If that does not work then Reflash your kernal as you did before, or any other kernal that you want that is compatible with stock roms. You will probably need Odin flashable kernals as your CWM is not working. You can try flash the kernal via rom manager, not sure what the result of this would be if CWM is not being installed properly. Instructions for installing the kernal will be from where ever you download the kernal.
So all the above should enable you to bypass Rom manager for the backup, or fix the backup/recovery which should fix the rom manager backup/compatibility whatever issues, Hopefully

What do you mean the phone runs fine?? Did it ever boot up properly, as in get you to the home screen??
Have you tried reflashing the rom via recovery as you said it works...
If you use ADB you should be able to transfer back and forth, but there is a fairly long winded process to set it all up! However after this it should be easy..
If that doesn't work restore your backup which you should always make before flashing! (Im guessing your in this situation because you didn't do that? )
So if you don't have a back-up get an odin flashable rom either from stock firmware on sammobile.com or from the general forum where Ramad has made an extensive collection. Also you could flash DarkyROM 10.2 RE Odin ROM which is a custom rom and odin flashable..

I have heard frm sumwhere that we have to apply some update.zip two time to make cwm recovery working on sgs. Is it true ?
N which update .zip?
After reflashing kernel . Should ma rommanager detect recovery automatically or i have to do sum thing?

Have not heard of this... Sometimes you do have to flash roms twice that have kernals to avoid problems which may be what you are talking about. All custom kernals use CWM as it has many extra features. If you follow the instructions of the rom/kernal you should never have any problems.

It should work, possibly its a problem with the kernal I'm not sure. But I can say that every time i have installed and used Rom manager (I dont usually use it, so i uninstall it ) I have had to re-install CWM. What happens is i get a popup telling me to install the latest CWM, I then have to pick my device, I do so and then the pop up just disappears and all downloads are available to me. So in my case it doesn't even look like it installs anything as it doesn't reboot etc.
Soooo the answer is that it will probably tell you that you need to install the latest CWM, so just follow the prompts and if it installs the latest then great. Hopefully it will work after this. If it doesn't you may have to try a more recent kernal. If that still doesn't work, then use Odin to flash a rom.
Odin flashable custom rom that usually never fails for anyone This rom is usually recommended to people with problems. After this you should have CWM and be able to use Rom manager like it should be used

Why are you so attached to rom manager?? You think its safe? Probably agree but you may have to dump it for the first flash and then get back to it once you can get it working.. If changing kernals doesn't work then it may be your stock rom, and to change will either have to be odin or a zip via recovery...
Hopefully all goes well, Good Luck
REALISATION...
This is all because you cannot get a backup... If the above does not work then forget the backup and just flash the rom via rom manager. Because even if you have the backup you wont be able to use it as you don't have a CWM recovery right??
The apps i use for backup
App list backup
Sms backup and restore
titanium backup

[Q] Brick GT-i9000, Can't flash rom using CWM

Hi all,
I've searched most forums and google and nothing found that I can use to revive my GT-I9000.
For background, I just rooted my galaxy using
* SuperOneClick and install TB, etc
* Install CWM by using CF-Root (I prev. have Android System Recovery (3e) and so need to follow addictivetips how-to-install-clockworkmod-recovery-on-samsung-galaxy-s-i9000)
* Take Nandroid backup of original firmware
* Flashed CM7 and CM9 back and forth with no issue.
My problem started when I thought I could just use the nandroid backup of original firmware and remove the bloatware, because CM9 is not on stable version yet.
The nandroid backup can’t boot up, so I goto recovery mode and try to reflash CM7 and CM9. The CWM from CF-Root can’t mount the SD card anymore, thus can’t flash the ROM.
I flash the “hardcore-speedmod.tar” from Full_Update_Guide using ODIN and got to the CWM 2.5.1.0 and can see the SD card, but when I try to flash CM7 or CM9, it says “assert failed: getprop (“ro.product.device”) == “galaxys” and a whole bunch of getprop with Status 7 and installation aborted at the end.
This is the same CM7 and CM9 that I used many times before and still in my internal SD card.
I've tried wipe data and cache but doesn't work. Going to Download mode or Recovery mode is not and issue though
I could try restore all from the nandroid backup but it says be carefull, so i hesitate as not want to make it worse. This nandroid backup is also created from diffrerent recovery (created using 3e and now CWM 2.5.1.0 that's running) - Update: took my chance but didn't work as can't mount
I’m not sure how I can copy other files into the internal SD card as well (in Windows).
I’m at my wits end and have search a lot and tried many things.
Please help
Cheers.

Try flashing some older stock android version over ODIN first, than root etc all over again. I had a similar problem just weeks ago and it did work for me, after screwing with it for 3 hours... Will search for some links and post them here, if I find them..

Go look in ask me anything I have the answer, there's a basic guide to save your phone, I have used it a few times and I have saved my phone from the situation u are in.
If you like my posts hit thanks

Last post before I go to sleep with a smile on my face.
For those who might have the same problem, below is what I did.
Did the "[ROM][ODIN]noobfriendly stock jvt firmware (root included)" thread to the T and works the 2nd time. 1st try almost killed the phone with BSOD appearring though.
Thanks for the tip jerdms.
IT'S ALIVEEEE.

cynogen not showin on external SD!!

Hey I have an optimus 2x.
i was running stock gingerbread on my rooted device. the other night i installed rom manger and downloaded CWM straight from there for my phone. it was version 6. something. i booted into recovery. made a nandroid backup(into the external memory of the phone) . then awhile later for some small reason i restored that same backup, which restored but it sent my phone into boot loop. the lg logo just flashes on and off.
i then heard that i may have installed the wrong CWM so i put another version of recovery onto an sd card and flashed it onto my phone.
cwm-based recovery v5.0.2.7
Now i have this recovery but when i try to restore that same backup it restores it really quickly and says it cant find a bunch of stuff.
i tried to put cynogenmod on the sd card but my phone doesnt give me the option anymore to install zip from external sd.
i have been reading and reading. currently i am on your thread called full brick repair.
i just dont know which way to go. i cant even find a stock ROM. the links i found are broken. I am in canada. its a fido phone.
i have tried A lot.
ANY HELP IS APPRECIATED . Thank you.

Now you have older version, when backup have been made by newer version. You have to flash newer version of CWM and then wipe data,system and restore backup. It will work
If you want to back to stock, use nvflash toolkits that are floating around here.

The reason i installed the older CWM is because my phone kept bootlooping after restoring the backups
ANYWAYS, i manged to flash the latest cm10 andGapps on my phone. its a bit laggy
what i am trying to do tho is use setDNS an app. to change my dns settings in order to get the american content from netflix.
setdns has superuser permisions and all but i still get the canadian version of netflix.
i think its because of CM10, what should i do?

[Q] CWM can't find my Recovery Touch

My device is a P990h, wich is the same P990 but fabricated here in Brazil
I installed the LG v28G Stock ROM this weekend on my app, coming from a CM7.2. At that time I had CWM 5.5.1.5 and CWM Recovery Touch 6.0.1.5 (payed with paypal) with plenty of backups.
But now CWM doesn't detect the Recovery, prompting me to install it. When I chose to do so, it doesn't detect my device saying that it is not supported:
LG-P990 does not have an officially supported ClockworkMod Recovery yet. Have you installed a ClockworkMod based recovery manually?

As I was concerned with a possible irregular functioning, I said that I did have it and chosed the second option (v3 and higher). Now I have CWM Recovery v5.0.2.8d on my phone and can't find the old backups and stuff anymore!
What should I do? Is it happenning because CWM really doesn't support P990's ICS? How can I upgrade the recovery tool to the newest one?
I'm thinking of installing a v30a stock ROM on my device, since v28G isn't matching my expectations, but I can't put it on with this issue bugging me
