Hi, i have a samsung galaxy ace, my network is now doing ota updates to receive 4g, I want to try it so..
I need to go back to my stock ROM (after flashing a custom one) I did a nandroid back up before flashing so exactly how do I do this, do I need to wipe cache etc? In fact instructions would be appreciated,
Also, can I receive ota updates on a rooted device? If not, how do I unroot?
Thanks xx

Galaxy Ace can't use 4G networks due to the hardware it has
Restore your backup:
1. Wipe data/factory reset
2. Wipe cache partition
3. Wipe dalvik-cache
4. Restore your nand
To unroot you need to flash unroot.zip file

Hello i successfully rooted my galaxy note and overclocked it im running darkynote rom but want to change to a new, But firstly i want to do a fresh install delete everything apart from the kernal and root, Do i simply just go into
Privacy, Factory data reset ?
First of all, you want to do a backup of your existing system and data in case something goes wrong. The way to do this is
1. reboot into CWM Recovery
2. choose Backup and Restore option
3. Backup
and CWMR will backup everything. Restoring is just as easy (if something goes pearshape with your new install).
Usual steps when flashing new Roms are
1. reboot into CWM Recovery
2. wipe cache (2 times)
3. advanced/wipe Davlik cache (2 times)
4. factory reset (2 times)
5. install zip from sd card (this is your new Rom)
However, bear in mind that some Roms have different flashing procedures, so you'd do well to follow closely flashing instructions in their respective threads. Those can be usually found in 2nd or 3rd post.
Hope this helps.

Refer this lucid guide for all your need for flashing a new ROM on your rooted Gnote: http://forum.xda-developers.com/showthread.php?t=1424997
I hope u are aware with every custom rom flash, you change your binary counters and that this will hamper your warranty claims, in case of needful. Nevertheless, its always useful to be enterprising... so good luck!!

From my understanding if you are running an ICS rom you can upgrade without wipe if it's an update to the same family ROM. Otherwise, i would recommend performing a wipe first since you'll have remnants of the previous Rom installed still and have no way of knowing if any elements are interfering with your new install.
I use App Backup and Restore for my apps and SMS Backup and Restore for messages. Doing this means wiping isn't half as laborious as without at least these items backed up.
Maybe it's a bit overkill but i always backup what i need. Wipe, Install, Reboot. Let the phone do what it needs to. Reboot into recovery and factory / wipe / clear cache and fix permissions. I rarely get any problems this way.
Maybe this is helpful to you.
Thanks for sharing.
As per you above comments i can directly flash the ICS dark Knight rom from the current SGS RC4.2 rom by just flashing from the recovery mode?

ya you can.. but its always better to do a backup of your apps/ data and do a factory reset and then install a new rom through recovery.. a fresh install would prevent any problems... also in every rom's op the install instructions are given.. better to follow those as you'll be able to get better help in case of any problems..
Thank You..Point Taken !!
Hi all, last night I flashed this ROM to my phone I9000XXJVU_I9000OXAJVU_OXA and then flashed ICS_4.0.3_MR1-RC4.2_I9000 over the top. This all appeared to go well and booted up ok.
I then used TB to restore the backup of apps etc to use in ICS. TB ran as expected and the progress bar showed that all the apps had been restored.
From here I went to the launcher page > applications to check the icons were there and guess what ----- no piffing icons.
Searching the file system I could not find any reference to ANY of the restored apps from TB.
So !!!!!, what would be the correct way to restore a TB backup in ICS 4.0.3. Things like the sdcard seem to be in different locations also.
If some kind soul could work with me to resolve the problem that would be great. On or off list.........
If your TB backup was made with Gingerbread then you can't use it for restoring in Ice Cream Sandwich.

You could restore apps only, not data. There are several tutorials in the development section, for each custom I9000 custom ICS ROM, check them out.
Try another install, wiping again cache and factory reset and try to restore only apps, not apps data.

This applies for CM9 ICS, but is pretty general for other ROM's as well, unless they have specific requirements:
- First time flashing ICS to your Galaxy S (or coming from another ROM)?
Root your device and install ClockworkMod Recovery.
Reboot into Recovery using 3-button-combo
Do a Nandroid backup!
WIPE (wipe data/factory reset + wipe cache partition)
Install the ROM from internal sdcard using ClockworkMod Recovery
Optionally install the Google Addon
WIPE again or Calendar Sync will not work.
- Upgrading from CM7?
Do a Nandroid Backup!
WIPE (wipe data/factory reset + wipe cache partition)
Install the ROM from internal sdcard using ClockworkMod Recovery
Optionally install the Google Addon
- Upgrading from another CM9 (or teamhacksung) Build?
Do a Nandroid Backup!
Install the ROM from internal sdcard using ClockworkMod Recovery
Optionally install the Google Addon
Note: The upgrade process from CM7 to ICS is automatic, but downgrading from ICS to CM7 (or restoring Nandroid) requires flashing twice. Once from ICS and again from CM7's recovery.

Please note that this might not apply for your specific ROM and you might brick your phone if things go wrong.
Ideally try to find the specific instructions for your ROM.

Thanks agian dsecareanu, i'll investigate some more.
Hi there,
I recently rooted and flashed a custom ROM onto my Samsung Galaxy S3 Mini. I'm very new to this thing and find everything quite overwhelming, but I want to learn.
I flashed this ROM - http://forum.xda-developers.com/showthread.php?t=2119219 (the v6 No Wipe version because I was petrified about losing my data if I factory reset), but the phone is now extremely laggy and buggy, so I want to go back to the stock ROM (so I can do a nandroid backup) and then try a different custom ROM like Dmod.
So, my question is, do I have to factory reset my phone to go back to stock? Or can I just flash this file (http://hotfile.com/dl/189271016/833...T-I8190N-BTU-I8190NXXALL6-1356151513.zip.html) using the CWN recovery menu without wiping? I'm asking because my phone keeps giving me an error everytime I try to backup using the CWM Recovery menu.
Thanks and if you need me to explain something in further detail, let me know.

That firmware is a zipped odin-file. Can't be flashed in CWM.
Make a cwm nandroid backup of your "/data" to your external sd (that's your installed apps)
You can also backup your apps and appdata using titanium backup or similar, for later restore.
Just remember to never backup/restore systemapps.
Backup internal sd to computer just to be sure, if you in any situation have to make a factory reset. Make sure any kind of backup is on your external sd before you make factory reset, or it will be lost forever

Backup your data in CWM, flash my ROM and restore your data with CWM.

CWM has NO choice to backup/restore only parts of the device. Only a full backup is possible.
This is only in TWRP. Pity! I only use CWM because TWRP makes corrupted backups (three times) for me.
Or is it possible to pick out only DATA from the backup? And what is happen with the dalvik cache, which
consists of the byte-code for all installed apps, optimized for the ROM which created it?
"advanced restore and restore only /data". Is this the way in CWM that you mean @benz?
JackoMJ
Yes that's exactly what I meant, "advanced restore and restore only /data"
You don't have to worry about cache and dalvik because it's automatically created on the initial start.
thx for the information Benz (usefull in the future perhaps),
but i´ve decided to use Titanium Backup.

Hi OP!
Thanks for this article, it really is helpful,but I have 2 questions about it:
if I want to use the linked "ROM: Original stock ROM, UNROOT and UNMODIFIED." on my rooted, TWRP recovery 815 device , I will have to unroot my device also have to install stock recovery beforehand, am I right? Because if I try to install it via Odin it will brick my Tab S2.
I am asking it, because it was more than half a year since I updated my Tab S2, because it has stock ROM on it, with TWRP and root and I didn't wanted to deal with everything before update (unroot, stock recovery, ROM install via odin, twrp install again, root again etc.), since there is not stock update that I could istall via TWRP unfortunately.
My other question is what is Chinese special version ROM(T815c)? Why is it special? I am European so I don't speak Chinese either, not to mention my device is the basic 815, not 815c.
Thanks.

Hi, if you want to update your system to the latest version, I'm afraid in most of the cases you'll need to unroot at least unless your supersu has a recover OTA option in it, otherwise if you want to flash ROMs that I listed or other ROMs need to be flashed with Odin, you'll need to clear all the data in your device and flash, of course you can directly flash it without any wipe, but possibly something will go wrong. In your case if you only want to upgrade your system, you can find other ROMs here in xda and flash it with recovery, but even if you use recovery, there's no guarantee that nothing will go wrong without wiping anything. My suggestion is to backup your data first, and maybe find a recovery update package and directly flash it with recovery, no need to unroot or wipe other than Cache, but in case anything went wrong, you can use ROMs provided here and flash them with Odin to recovery your device, of course, if something went wrong, you'll have to wipe everything to do that.
About the Chinese version, if you don't use the T815c version, thedn you don't need to care about that, it's for Chinese buyers who bought the Chinese version.
Let me know if you have further questions.

Could you send me a description how to unroot? After that I should flash the stock recovery via Odin and flash the ROM via Odin as well, am I right?

Actually what you should do is to wipe all the data in the phone and then flash the ROM, no need to unroot or flash recovery separately, wipe can do all that for you, of course if you don't want to wipe all the data, you can try and directly flash the ROM(it's risky but sometimes it also works perfectly), then if something went wrong, you can wipe the data and flash again to recover.

I did not know it should be that simple, I owned a HTC, LG and Huawei phones but in all of them I have to unroot and install the stock recovery.
Oh, ok. I should do a full Wipe with Odin? I know there's an opinion in TWRP too.
