What's the best way to recover from a bad flash. I am currently rooted and on a bloat free stock rom. If I try to load another rom and it does not work out, can I come back to my present ROM state? Any instructions on how to do that?
Thanks

All this info is found by searching. Look into nandroid backup. This is done from recovery.

So like most of us here I enjoy testing out the custom ROMs, but also like to go back to stock when I`m done testing.
Can NVFLASH be used to (without root, I am B40 anyway) make a FULL backup of system, boot, recovery, so once I am done playing with a custom ROM I can get back to exactly where I am now with my stock ROM ?
If that is possible, is there a .bat file I can stick in the NVFLASH folder to do this? Or any other way ?
Reason for this is to avoid having to root or flash CWM, and to make sure 100% my OTA updates will work again when I flash back.
You might want to look into this, http://forum.xda-developers.com/showthread.php?t=1123429. I've used this tool to get back to stock, with B60 series.
Yea I know how to get back to stock thanks, I want to make a full backup of my own stock ROM I am running now using NVFLASH to back it up
I know NVFLASH can flash back to stock
I want to use it the opposite way, and backup my current system, same as CWM can do

Thanks, looks a little hit and miss as to if it works or not due to encrypting.
Hi,
I have followed everything in this thread http://forum.xda-developers.com/showthread.php?t=1837863
I have backups nandroid ready and wasn't too sure, if I dont like this build then i could restore back to stock using CWM? or Odin.
I felt that I need to wait for reply to comfirm before flashing this cyanogenMOD 10.
Thanks!

IF my memory serves me right, with an unlocked bootloader, you can recover to a TW rom but I think its needs to either have the kernel built into it OR you need to somehow flash to a TW kernel. I say this because I think that if your kernel is still an AOSP one, then the device will not boot up.
some roms already come with a kernel for their rom so I think in most cases, with CWM 6.0.1.x, you could restore a TW nandroid.
If you want to restore a backup of a TouchWiz rom you have then just use the EZ Recovery app to flash the hybrid (CWM/Kexec) recovery...reboot to recovery and restore your nandroid. Simple process!
Once the Dev's building TW roms start using the non-kexec flashing method then you will be able to restore using the normal CWM recovery. Just like you said, you can also use ODIN to restore to stock but it's a pain because you have to root all over again. Just know you have a few options.
Ok thanks everyone!
So good
Fwiw... I've been switching back and forth between Synergy and CM for a couple days now (flashing multiple times) and cwm touch works for synergy but u need new cwm for CM10.

you can try backing up your stuff with titanium backup and then doing a factory reset and start from scratch or you can look for the stock rom zip online and flash that...

How did you try to flash the RUU? You can not flash it like a normal ROM
Also if you are looking for the RUU try HERE
I see what you're trying to do, that won't work...you can't flash a recovery to get to stock because stock phone won't flash from recovery, which is why once you get root the first thing you do is flash a custom recovery. Use the RUU to flash it back to shipped state stock, or if you are trying to keep root and just want to use a different ROM. More clarification on what you are trying to accomplish would be nice.
If you did a Nandroid prior to flashing CM10 I would wipe all partitions except SD and restore the Nandroid, if all you want to do is get CM10 off your phone. Remember Nandroid Backups are your friend do them before flashing anything and save them to your PC if you don't want the SD space taken. Doing this has made flashing pain free and hassle free. If I don't like how my phone is running after a flash I can always get it right back to how it was when I was happy with it. Lastly there was a time when I had a Nandroid backup of a Sense ROM and was on AOSP and wanted to flash back to Sense, well my Backup wouldn't flash. After spending hours raising hell I did a clean install of the ROM booted once, then rebooted into recovery and flashed the Nandroid backup that had the settings I was using (when I was on Sense, it won't restore data and apps used on AOSP)...sorry if its not much help but more details are needed. But you have a starting point.

i have installed CM10 without backing up any image, therefore i cannot restore the orifginal vendor's rom. Nandroid back would have prevented this situation. the second problem is that I couldnt find any RUU for this phone. indeed the link you attached seems to have it bu unfortunately it is in chineese and after pushing all the buttons i couldn't download the file. so my options are
1- to pray that someone will be kind enough to publish it in a manner that it is accessible
2- I have a friend with a simillar phone , can i somehow back up hus rom and restore it in mine ????
thank

Hey all,
So I have been reading around a bit now and was wondering if someone could help me understand some general concepts.
my goal: I am trying to remove all the bloatware from a Huawei y300 (no carrier) and put stock android on it.
From what I have been reading, it sounds like I need to first unlock the device, then root it to get access to superuser. Then what? Can I just use the superuser to remove the bloatware? Or do I need to flash it all and install a custom ROM?
Also, I should prob back the whole device up first so that if I mess it all up I can still restore the phone to the way it was when I got it from the distributor. Is that easily possible, or are there risks associated with that? If I mess up the phone real bad is there a big chance I will not be able to get back to its original state?
Now the details of how to do all this are burried in the forums, and I will figure all that out. I am just confused about the order of things a bit. So if anyone could give a high level explanation on the order of steps and the need for each that would be awesome!
Much appreciated, and thanks
The basic process is unlock the device, root the device, flash a custom recovery, flash a custom rom. Flashing a new rom is what will remove the bloatware for you, and you can find a stock android rom that will literally be the barebones version of android. Rooting the device allows you access to flash the custom recovery, which is needed to flash custom roms.
Everything as said above, with a nandroid backup added as soon as u flash the custom recovery is recommended.
BTW there are chances that u can brick ur phone if u don't follow the custom rom flashing instructions properly.
Anyway the nandroid backup will help u in this case.
In case if the nandroid backup even fails, which means there is a heavy mistake also there are very less chances of it to happen, u can try flashing the stock firmware.
Hit thanks rather than typing it
Got it thanks!

OK so I unlocked, rooted, installed TRWP recovery, and then used that to back up my phone. From what I read online it looks like backing up with TRWP is the same as backing up with Nandroid. I'm prob just not getting it, so wanted to ask what is the significance of Nandroid? Why do both TRWP and Nandroid?
