I'm running stock Vibrant 2.2 from mini Kies. I have rooted and installed Titanium.
What I want to do is do a backup with Titanium, reset to stock 2.2 for some GPS testing, and then restore to my current state.
How do I do the reset?
Also I'm unclear on the restore. Will I have to root it again before I restore?
hope it helps.
Well first id make sure you have the 3e recovery set up, if you do then install the app Rom Manger off the market. flash the clockwork recovery from the app. then you can do a Nandroid back up. With this back up you can then restore to the moment the back up was made when your ready to. If you reset to full stop and remove root and all that stuff, you will need to add the root and 3e recovery again before your able to do the restore.
the link is to show you how to install the 3e recovery. And you can get a one click root prgm too

As for the reseting to stock, you have 2 choices i can think of. You can either odin back to 2.1 then upgrade to 2.2 again, or you can use a one click root prgm to unroot your phone, then do a factory reset to it. i normally always do the the odin to have a fresh start when i want to make sure everything is in working order but thats me.
information on odin and other basic rooting help.

The main thing to remember is to always read and reread the instructions on what your going to be doing to make sure you understand it fully.
You lost me on the "your on stock 2.2, installed titanium, and now you want to restore to stock 2.2." Your already on stock 2.2...

What I meant by restore to stock 2.2 is put the phone back into the state it would be in if I took a phone straight from the factory and did a mini Kies to 2.2. Presumably that means deleting all apps I added and putting all settings back to the defaults. I would hope I would not have to reload the rom, since as you say I am running the stock 2.2 rom.
In this 'stock' state I can run some tests, and if necessary send it in for service.
However, I want to be able to quickly restore to the apps and setting as they are now.

Thanks for the detailed info. It may come to that, but couldn't I get the effect I described above with a Titanium backup?
clarification
Well with Titanium backup you can back up your apps, but thats all it saves, if you have like a lot of settings changed on your phone or ringtones set for people and stuff it doesn't help with those. But a Nandroid is a full backup of your phone down to settings phones ringtones etc. Normally i use Titanium backup when i'm going from ROM to ROM to quickly reinstall my apps, but if your doing a rest and don't want to go about re setting everything then a Nandroid is th way to go. Hopefully that clarify why i recommended it.
I am pretty much trying to double check and make sure I have done everything needed before installing a custom ROM. I have a LG P509 from T-Mobile. I rooted my phone and backed everything up on my SD card using Titanium Pro. Then I installed a custom recovery (Thunderbird) following instructions from the forums. From recovery I did a Nand backup. I chose Nand+extra+android_secure. (I am unsure if that was the right option to choose, if not can I just delete the nandroid folder from my SD and repeat the process the right way?). I replaced then lost my original boot animation before backing up, does that really matter? I was reading about a custom ROM and it said something about "requiring AMON_RA recovery". I used thunderg and was wondering the difference, if I should install it and how to do so (if its the same process/where to find the files)? From everything I have done I should be able to recover to pretty much my stock phone, correct? One last question, does installing ROM and/or kernals completely erase, reformat my SD card? I have read up a ton but some things haven't been fully clear to me. I know these questions have probably been answered a million times so I thank you for all the help and insite! If I missed or forgot some things please let me know as well, thanks.
You are ready the method to back up also fine now just download rom u like and flash it.
No installing rom doesn't format ur sdcard. But some rom requires u too partition ur sdcard that's where sdcard gets formatted.
The recoverry u install is old I think u should flash new ones like amonra or cloakwork but be aware that the nandroid backup of different recovery is not compatible with each other.

first if u want amonra orelse clockwork which can be found here http://forum.xda-developers.com/showthread.php?t=1024838 just place the file in ur sd card root and flash from recovery then reboot. DONE! u can find the latest amonra recovery here http://forum.xda-developers.com/showthread.php?t=1065197.
now when u install a new rom and wipe ur sd card then obvious that it wipes ur sd completely as some rom require to create ext partition so keep all your backup safe in pc too.
Boot animation is not an issue at all.
as for the backup nand we normally choose nand+android secure (in case no ext partition) and nand +android secure+ext (in case of ext parttion) i am not sure about the exact lines as different recovery might have differnt option type but moreorless they are same.
note:if u flash any other recovery like amonra or clockwork it is better to create a new backup using the latest recovery
I'm about to flash my first rom too. After reading alot and trying to undestand all those procedure is hard, as english is not my primary language. Recently I have install root and install costum recovery 1.2 from terminal emulator and did some nandroid backups. Also did a stock recovery backup.
My phone is stock and my provider is Telus. Do I have to unlock the phone or anything similar before flashing a new rom?
Not sure if it works on a locked phone, guess it will.
Just give it a shot, you can restore your nandbackup any time if it fails.
Hi
I would like to install mik's cm7 ROM but there are some things which I did not understand (never installed custom ROMs before, so I'm a noob):
- which recovery should I use? Amonra or Clockwork? (some explanations here contradict others, so it's not clear to me: should I copy in my SD card root both recovery.img and signed_recovery files? Because in the clockworkmod recovery topic I only found the archive containing the recovery.img file, no signed_recovery anywhere. Also in the ROM Manager app there is the option Flash ClockworkMod Recovery - can I flash a custom recovery just by pressing this option?)
- do I need to partition my SD card for this ROM? If it's necessary, how should I do it best? I mean, I was thinking at 32mb cache, 1mb ext2 or 4 and the rest fat32. And what is the real use of this partitioning?
Sorry for asking a lot of silly questions, but there is no real full tutorial for noobs here, and reading all the explanations spread around the forum is kinda confusing.
Thanks in advance
Thanks. I went ahead and flashed to the new recovery, worked perfect, and made new backups. Just waiting to get to a computer to backup to PC.

I'm not going to just give a try as my knowledge about the whole thing about flashing is new to me. I don't want to brick another O1 So many user here and no straight answer, wow!
I just want the right tools to proceed to flash as smooth as it can be.
Again do I have to unlocked the phone or do anything else before flashing a first custom rom? The phone is stock, beside root and custom recovery.

From what I've read here it works only with P509 ROMs; P500 ROMs don't work.
wrong please delete it.
Okay. Couple days ago, i got my new Samsung Galaxy S II. Fell in love with it. I previously had a Vibrant, but that met an unfortunate and violent demise. On the vibrant I hadn't been doing anything involving roms and such because i'd tried once, and completely fried the phone. LOL.
I managed to root my phone, and from what I've read, I didn't do the best method. What I did was get an unsecure kernel, and flashed that, then used a 1-click root type thing to root it. So one of my questions is, my clockwork mod isn't working, what's wrong with it? I downloaded ROM Manager, and flashed CWM. But when i reboot into recovery, i get the stock Samsung recovery screen. How can I get this to work?
And another question, is about roms such as Cyanogen mod. I really wanna get it. (I wont until I get CWM working, though.) And I'm just wondering. If I were to just go to ROM Manager, and flash cyanogen, would it work, or do i need to do more to my phone to be able to put on custom roms? I've never understood the concept of roms vs kernels vs firmware vs whatever else.
And if it matters, Samsung Galaxy S II, Android 2.3.3, rooted using SuperOneClick.
P.S Anything else that I should considering doing/putting onto my phone? And thanks in advance for halping.

Okay, don't take this the wrong way, but it seems you're a bit lacking regarding knowledge about this phone... It'd pay to do your research beforehand in the SGS2 forum, read the FAQs, etc.
Okay, first off, all I can say is, go back to stock. Go flash a stock Samsung ROM for the device. Then, go into Chainfire's CF-Root Kernel thread, and download the appropriate kernel, and flash it using ODIN. After you've done that, you'll have ClockworkMod, and you'll be rooted. It is recommended that you flash another kernel though, after gaining root, as all the CF-Root kernel does it install ClockworkMod, and root the device. Personally, I recommend SiyahKernel.
If you need more detail or have any more questions, feel free to send me a PM.
Thanks,

Alright, I did what you said. I went to stock 2.3.4, used CF-root. And now about SiyahKernel, what are the advantages of it? And is there something wrong with just staying with the CF-Root kernel?
And as of where I am now, with just root and CWM, would i be able to switch ROMs and such?

With a rooted device you'll be able to flash trough Odin or CMW recovery any rom you like.
Siyah kernel gives you a faster and more battery efficient phone and lets you set your own Voltage/ speed the processor has to use see this for the latest info

SiyahKernel has a lot of advantages and improvements of CF-Root, which provides null, if I'm correct. Go check out the SiyahKernel thread in Original Development for details.
Yes, as stated, you can use CWM by itself to switch ROMs. Just remember that if you're switching ROMs (as opposed to performing a flash to a newer version of the same ROM), to perform a factor reset / wipe data, wipe cache, and wipe Dalvik cache (Advanced > wipe Dalvik cache) in ClockworkMod first.

For a beginninger, I can't recommend MIUI highly enough. You could go with GalnetMIUI, which is a variant, but I personally prefer the official MIUI build. If you're looking for a more, 'pure' experience, go with CyanogenMod 7.1 stable.

Alright, one more question, sorry for the nooby-ness. Haha.
So going from my phone to for example Cyanogen, I'd backup in CWM, and Titanium backup (Or does CWM backup like, EVERYTHING?) and then factory reset, flash the rom using odin, and then use titanium backup to get my apps and settings back? orwhat.

CWM backup (called a NANDroid backup), backs up everything. If you perform a NANDroid back, there's no need to perform a backup in Titanium Backup - it creates a full image of your system (the advantage to TB though, is that you can backup all your download apps and settings, then install the new ROM, and restore the backed up apps - If you restore a NANDdroid backup, it'll restore the old ROM, exactly as it was when the backup was made).
So yes, the installation process is, for CWM: copy the ROM.zip to your phone, then boot into CWM recovery. Hit the 'factory reset / wipe data' option, the 'wipe cache' option, and then go to Advanced, and hit the 'wipe Dalvik cache' option. After that, choose 'install ZIP from SDCARD', and choose your ROM.zip. After it finishes installing, just hit 'reboot system now', and you're good to go!
Usually, it's not required to use ODIN to flash a new ROM, unless there's a problem with the recovery.
All that said, it pays to read the thread for the ROM beforehand, as sometimes when moving from ROM to ROM (especially from stock), there's a few small things that may be required, like flashing the ROM twice, or whatever

Alright, i got that done. I've tried both MIUI and Cyanogen, and both are working and lookin wonderful. But the problem is I dont get data on either one. I've tried reflashing, rebooting, factory reset. Idunno what else to try. Do you know what could be causing this?

Check your APN settings (should be somewhere in Settings under mobile network or whatever). Look your's up online ('APN settings carrier y, country z), and if they're not correct, add them in.

You're more than welcome
If you've got any other questions, feel free to PM me
With CyanogenMod, there's a bit of a story to it, but basically, they're not allowed to package Market, Gmail, Maps, etc. with the ROM, so you need to download a zip file called Gapps and flash it in CWM Recovery, you can find it here. You don't need to wipe anything when flashing this.
Also, build #115 isn't the latest, build #117 is (in fact, there's another, even more current one, but there's really nothing to it), but I don't believe there's any major changes.

Hey, I was having troubles messaging you, since it didn't show anything in the sent box, i assumed it didnt go through. So i guess ill be still asking you on here.
So about Cyanogen, which build is the best? And if i'm going from one build to another, like from 115, to 116, would i still have to do a complete wipe? And any other roms besides MIUI and Cyanogen you recommend? cause MIUI is giving me and couldn't generate md5 errors, and i cant restore to it, and i hate starting off without it set up how i like it. D: and yeah, thanks.

I only just the message 12 hours ago, if that helps?
Usually, your best bet is to go with the latest build, which you can get here. If it's stability you're looking for, go with the stable build, instead of nightlies.
Personally, out of all ROMs I've tried, I could only ever stand MIUI and CyanogenMod - but even then, MIUI started to annoy me with little things here and there. I think I'll be sticking with CyanogenMod for awhile. So, I'm not really the best authority on that. Just try some different ones, and see what appeals to you the most
Recently my phone has bricked, every time I connect it to a power supply unit, it boots, but the boot process stop right before the actual loading of the UI (stuck on the second part of bootanimation). Well, I think I could fix this by restoring the stock /system/fonts/ folder content (because I alterated it right before bricking). So, how could I push those files into the phone without being able to load the UI?
Stock S3 ROM JB 4.3 build MK6. Stock recovery. Can get to recovery and download mode. Tried with adb, but there's no way (installed drivers, java SE, kies, Android SDK, Google drivers, uninstalled all, reinstalled all, uninstalled kies and so on..). I would prefer not to lose my data, because I don't have a recent backup. Actually I thought to install a custom recovery and hence move the files I want to the location I want, but installing a custom recovery could make me lose my data.
Thank you.

I have been flashing roms for years and never lost any data by flashing a recovery just make sure you read the guides and you will be ok.Make sure if you do flash a recovery to backup your data before attempting anything else..But remember to backup just your data not the rom because you will be backing up a faulty rom (because you altered/deleted the system fonts)

My point is your are in a bootloop because you messed with system files! I was stating that your chances of losing data because of flashing a custom recovery are low and by doing so you can back up your data in recovery and get yourself out of a bootloop.
I suggest you do a lot more reading or you will mess up your phone even more this is a easy fix if you read the stickies and tutorials..

Oh ok, now I got what you intended. However I really didn't any massive modifying to the file system, I just wanted to change the fonts, I didn't think I would have needed a guide to follow and warnings about that.
I have a Samsung Galaxy Tab S LTE (SM-T805). When I do "adb recovery" or when I do "power+vol up" it boots into a "revovery" which says
Android system recovery <3e>
LRX22G.T805XXU1B0D1
etc
I would like to know,
1) is this part of the original/stock Samsung firmware/software, or is it something that was downloaded on the tablet by the previous owner? (I bought the tablet second hand)
2) do I need to install another bootloader if I wanted to install another ROM or is this good enough?
3) could someone please tell me how to install another bootloader?
Many thanks
1) 3e is the stock recovery.
2) You should not need a new bootloader if you are using roms based on the same firmware - LRX22G or similar
a) If you need a new bootloader, it will be mentioned by the developer of the rom you are using.
3) I believe what you are actually looking for is a custom recovery - this is needed to install roms that are not signed directly by Samsung.

2) I have also installed and tried different ROMs, like liquid-something, ice-something, ironman-somethhing. Does this mean that my tablet now "remembers" that it has been hacked somehow?
3) I forgot to backup the stock ROM, before I installed other custom ones. Where could I get the stock ROM from? I have looked for it but I cannot really get my hands on it.
Many thanks

1) Sometimes developers will provide a link to the stock recovery, but I did not see one when glancing around the forums. If you use the method mentioned in step 3, then you will be back on the stock recovery.
2) No. As long as you wipe /system, /data, /cache, and /dalvik cache then nothing important will be left from any previous rom flash. (Some roms will leave folders on your internal SD card that you can delete manually).
3) You'll find the stock rom here. This would need to be done in Download Mode with Odin. This will overwrite everything on the tablet and be like it was brand new. http://forum.xda-developers.com/galaxy-tab-s/general/samsung-lollipop-range-tab-s-t3021612

Again, many thanks.
The link you provided further directs you to some weird paid-for download sites, could not get anywhere with them. I would not mind paying say 10p for a one-off file download, but they want you to pay monthly etc, seriously...
However, for UK generic ROM, I got this file "SEE-T805XXU1BOD1-20150511102748.zip" which I got off some Russian or something web site, it was uploaded to Google Drive, so it was easy to download.
A serious issue I have discovered, and am not sure what the right steps are, is when installing TWRP, the installation seems not to "catch", so after the upload you still have the old bootloader. The way I got that to work was to uncheck the "reboot" flag in Odin, waited until the download was complete, and then after a while manually switched the phone off (I think it is menu+vol down+power) and then switched on again using menu+vol up+power and that got me into TWRP at last.
Anyway now it seems I am back to the stock ROM, and stock bootloader, and as you said, if I ever returned the tablet for a service they would not be able to tell that I had flashed other ROMs?
