Just wondering if i flash from 4.2.1 official back down to 4.1 official will i have to format my phone or will I lose anything on my phone if i am already rooted with my bootloader unlocked??
Thanks in advance for answers
Yes, data lost
To memory, a downgrade does require a wipe and if it's back to official, you will loose your root access. It isn't too difficult to get it back though. I recommend using Titanium Backup to backup your app+data and memorize/write down your settings so you can put them back into the phone later.

Is it okay to restore system data when using a new ROM?
I usually only restore the apps, but I have never restored the system data.
Also, I know that it isn't possible to receive OTA's after root and unlocking the bootloader. If I re-lock the bootloader and go back to the factory version, the way the Galaxy Nexus came in the box, is it possible to receive OTA's?
Good day! My wife has her phone rooted with the stock 4.54 ROM that was in her phone when I rooted it. Has anyone come up with a way to update her phone to the current 4.67 version without losing root?
I know that I can just get a rooted, stock 4.67 ROM and flash it, but that is going to freak her out...starting over, so to speak. I guess like a few others I'm waiting for a rooted 4.67 update for a 4.54 ROM. If anyone knows of anything that can help, it would be great. If I could just let her upgrade and then re-root it using revolutionary, I certainly would.
Thank you for your time.
Only option is to back everything up in titanium backup, mybackup root, ultimate backup pro or something similar flash a stock rooted rom and restore all the apps and data for contacts just sync to Google and SMS use SMS backup/restore from market

You could just do a nandroid, then wipe just cache & dalvik cache (I'd probably wipe boot and system too), then flash one of the stock rooted ROMs. That would preserve all the data, though it might cause some instability. But if it doesn't, you're golden. I might play around with actually putting together a rooted OTA zip, though I personally don't see a need for it. But that's a project for tomorrow.....
Thanks for the input, folks. I guess I'm going to go with the full backup of everything and flash the rooted stock. She'll just have to deal with it.
Have a great day!
Get Titanium or My Backup. She will lose call log and SMS. If this is an issue the get SMS backup. I flash a different ROM atleast twice per week and it is simple with Titanium. It usually puts every app back before I even open titanium. If something is missing you just go in and click restore.

So, per my post above, I was able to put together a rooted version of the OTA, but there are some restrictions on its use, unfortunately. It'll only work if you are currently rooted, and haven't removed any system apps. The OTA looks for each file that needs to be patched and if one is missing, it'll error out.
If you want to try it, let me know. All you have to do is flash it in recovery, actually. It's just like any other zip.
If my S3 is stock rom but rooted with cwm recovery loaded, will I be able to get the AT&T OTA JB update once it rolls out with no issues? I understand I might lose root, but is that it? I know it will be a couple more months, just want to be sure the phone will be able to get this with no issues when the time comes.

From what I understand, you need the stock recovery in place for OTA updates, otherwise they will fail. Which makes sense.
Ok that makes since, so closer to go time I can just put the stock recovery.img on there right?? Is it that simple?

flash to stock via Odin, so yes...
-Ryan
Or you could just wait until the update drops and somebody posts a stock rooted version and update it through Odin.
Ok so have to flash the stock rom itself and not just the recovery. I have only really used an older Galaxy S1 to mess with flashing and stuff and never cared about the apps and everything, just would put a rom on there and when needed put it back to stock(borrowed it for a couple months). So if I do a titanium backup of apps+system data I can flash the stock rom, I assume root again and then restore the apps? let it update and Im done, or assuming the stock At&T JB rom is available on XDA I can just flash it on there, root and restore from titanium? Those are the 2 options if I want to stick with stock right?

Right, but it's not usually recommended that you install apps+data with TiBu; better to just install apps only.
-Ryan
Got ya, I do a backup with apps and data to be safe, but you can just restore apps only from that right?

You can. Though could also just let the Play Store redownload your apps for you.
Hi, i hope i am in the right place, sorry if not.
I want to root my One X on stock ROM. I currently have 4.1.1, CID HTC_001.
Is it possible to get it rooted while keeping certain things? These things are:
Being able to receive OTA
Keeping all files when rooting
Easy to revert back if i am not able to receive OTA.
Help will be very much appreciated thanks
If you unlock the bootloader with htcdev.com and flash a cwm custom recovery you can make a nandroid backup of the current non rooted rom and keep it in a safe place. You can restore that backup anytime if you want to go back stock.
After that you are able to flash custom roms or just root the one you are running currently ......
You might void some warranty with blocking the bootloader !!!
Tip : ALWAYS DO A NANDROID BACKUP FROM THE STOCK ROM !!!
Thank you

Thanks a lot. Just what i was looking for. I will certainly be doing this at some point. Shame you can't just root it but at least you are able to back it all up safely.
When following any guides
Don't flash the recovery. Just use fastboot boot recovery.img
Instead of fastboot flash recovery recovery.img
This way will leave the stock recovery on your device which is needed to apply any otaupdates

Yes with the taken nandroid you can go back anytime....the only thing you have to remember is that when you took a nandroid backup the recovery of that backup is not stock, so after the restore you have to flash back the stock recovery before you can apply a official HTC update. But you can find that easily.....i have them also :thumbup:
That's great. OTA was something i really wanted, thanks. 4.2 is coming very soon and a possibility of 5. Just one more thing. Do you lose items on the virtual SD or does this not affect them at all?
Well do a full backup of the sd before you unlock the bootloader, it's sets the phone to its factory state and some say it wiped the sd but others say it didn't so that's a grey area for me !
Its probably the safest option, i will do that. Is using the stock recovery just as easy as using the custom recovery too? I read stock recovery and this insecure boot thing and it has a chance of bricking. Also i know a lot of articles are with 4.0.3 and 4.0.4 and 4.1 are different. I think 4.1 is the same as 4.0.4 though.
Well to be honest i'm not a big fan of rooting the stock rom ! I always flash a custom already rooted rom to have benefits of all the hard work that developers has.put into a rom. In my opinion a custom rom is always better than a stock rooted rom. So i don't much about the insecure root things !
What i do is : flash the custom recovery and backup the stock rom (keep that in a vault ) and flash a custom rom to play with !
Stock recovery has no use at all for me, i only need it when i want to update the phone with official HTC releases .....like they did to update to JB
ow and yes rooting and flashing on JB 4.1 are the same as on ICS 4.04 :thumbup:
Is it easy enough to go back to the stock recovery though if you have used the Clockwork one?
Yes it will take 3 fastboot commands while the phone is in fastboot USB menu
Fastboot erase cache
Fastboot flash recovery nameofrecovery.img
Fastboot erase cache
And the stock recovery is restored !
That's all !
Ofcourse the nandroid has to be restored before that.....you copy the nandroid backup to the phone and flash the boot.img from that nandroid (its inside the nandroid folder) after that you do a full wipe in the custom recovery and restore the nandroid, then you boot it up to see if it runs and after that you flash the stock kernel ! Easy and simple.......and you don't have to re-lock and unlock the bootloader anymore, it can stay unlocked the whole process
That doesn't sound too bad... Thank you very much for the help, i will certainly be having a go. Sorry for some of the stupid questions, i am quite new to all this. Bricking is the only worry for me, if i can avoid that, i'm happy . Thanks again.
No problem mate ! I was already helping somebody else tonight.....multitasking it is !
Hahaha. Well i won't be starting until i can get my hands on another laptop as my current is in a poor state. Damaged hard drive. can run very slow at times. I tried transferring SD to memory stick. But it was running at a painful speed so i stopped it Tomorrow i should be able to get another one to backup my things onto.
Hey,
Xperia M dual user here. Recently got the update to 4.3 Jelly Bean. I updated and of course lost the root. Now, I took a backup TA when I was rooted in 4.2.2. I am going to install CWM and try some custom roms. So can I still use the same BackupTA or do I have to create a new one after I upgraded to 4.3?
Thanks!

If you have taken a backup in 4.2.2 then restore it in 4.2.2 only to relock the bootloader and then upgrade to 4.3. Then take backup of ta again then do whatever you to do with your mobile.

Just for clarification, so I can only relock my bootloader in 4.2.2 because I took my BackupTA on 4.2.2. I will not be able to relock my bootloader in 4.3 with the BackupTA took in 4.2.2. Did I get it right?
Also, the problem is 4.3 doesn't have any rooting method without unlocking bootloader. I have to take a backupTA before unlocking for which I need root. So kind of in a catch 22 situation here.

Well that's what I had read somewhere. Not sure where exactly. Its always preferable to restore TA Backup on the same version which it was backed up.

You are wrong mate. There is a working method to root 4.3 without unlocking Bootloader but that requires you to be in 4.2.2 + Fully rooted + locked Bootloader + Access to Windows PC along with USB Cables and Drivers.

Although not recommended, you can restore your TA backup in any firmware version. Sometimes when you restore a backup taken in an old firmware version you get a bootloop that can be easily fixed by flashing the stock kernel again with FlashTool...
I'm saying that because I did something similar: before developing Nicki Root, I took a TA backup in rooted 4.2.2, unlocked bootloader, flashed 4.3 and rooted it by using CWM and then I restored TA backup I took in 4.2.2 and everything worked fine. I already did this procedure at least 5 times and it worked all of them, the only attempt I got a bootloop was after restoring TA backup while running a custom kernel, fixed by flashing stock kernel again
Another tip: create a TA backup with bootloader already unlocked too, if you ever need to unlock it again you can simply restore that backup, without needing to use fastboot and without wiping data partition

Hey that's a great idea! The phone will not reset at all.
You can restore your TA backup in any firmware as long as it is stock rom

Ah, I see. Thanks a lot guys!
You can restore it in any stock rom with stock kernel. I have restore ta 4.1 to 4.3 many times without problems
