Downgrading to 4.1 - Asus Transformer TF700

I want to downgrade from cromi 4.2 to 4.1. I have the latest twrp and bootloader installed. My question is, if I were to flash 4.1 will it work? I really don't want to end up bricking my tablet

No worries. The 4.2 bootloader works fine with the 4.1 rom.
You should do a clean install though. Wipe everything, don't restore apps from a backup, install them from Play Store, do not restore system apps either, just app data and such.
If you flash the 4.1 stock rom, you will loose TWRP and root though. Why not go back to the last CROMi build?

Ya I just went back to cromi 4.1. I was having issues with Bluetooth which is a known issue with 4.2

Stock rooted and unlocked

Okay so I'm stock rooted and unlocked and your not supposed to apply future otas because it'll brick the device.
Since there are no stable versions of jelly bean that's kinda outta the question for me.
If there is ever updates. Radio. Rom. Etc. Can I just download and directly flash through cwm? Will I have to wipe cache and dalvik? How do I reinact a ota updates through cwm

I'll take a stab at this:
I tried the JB roms but a little buggy for now, I'm sure they'll be stable as soon as the stable version of CM is released. For now I run Bean's custom stock rom build 10.
Root your device, unlock boot-loader and flash CWR 6.0.1 or 2 as you recovery. Now you can flash any roms you want. My method is as follows :
1- make a Nandroid back up, either from CWR menu or rom manager. Then use tit backup to backup all my downloaded apps.
2- go to recovery and wipe cache,data, system, and dalvik
3-pick a zip file from sd card
4- flash bean's rom
5- restore all my downloaded apps
6- profit
Going from Bean ver 9 to 10 I only wiped cache and dalvik. Wipe all if dev is asked for it or going from rom to rom, but only these two if you are going to a different version on the same rom.
+1 for beans.
+2 for beans as well. And don't worry, there will be stable builds of JB wayy before verizon sends out an ota of JB.
I just donno if verizon will make another ota for ics or release radio updates to fix some issues.. All I know is since my phone is like this I can't take any updates haha.

And how, pray tell, are you controlling whether or not you get updated? My understanding is a stock ROM will automatically accept OTA updates without prompt. sounds like a brick waiting to happen.
Stock roms have always prompted me in the past to update. Is it true they no longer prompt and auto install? Idk I really doubt that.

If you have a custom recovery, an ota will fail
And another vote for Beans!
Stock rom will not force ota without me being able to decline though. Right?
That's my main concern...

How Do I Backup the Operating System?

I rooted my S3. I have not unlocked it.
I would like to backup the android operating system, the apps, and the data before I allow the recent OTA update.
Based on my research, I believe I can use titanium to backup everything except the operating system. How do I backup the operating system?
I tried the Volume Up/Power/Home Button restart. It gives me the option to restore but not to backup.
What am I missing??

Thank you for the speedy reply. I did a quick search and found quite a bit written on installing a custom recovery including on the S3.
It appears that I can only back up to a custom ROM such as ClockworkMod Recovery or TWRP Recovery and not the base ROM as it is on the phone now. Is that correct?
I have ROM manager on the phone so I expect the ClockworkMod Recovery would be the way to go.
Nope, CWM and TWRP are custom recoveries. You'll have to install one of those in order to backup. Go onto the app store and search for EZ Recovery. Use that app to install the recoveries(it's the easiest way for someone new). Then you just boot into your recovery and do a backup of your current setup.
Download EZ Recovery and flash CWM then boot into recovery and choose the backup option.

Custom recovery will backup stock rom. You will not be able to install any OTA until untill you Odin back to stock.
Thank you for the replies.
I guess I should have included in the initial post that all I have done is root the phone......I think.
I never unlocked the phone with Ez-Unlocker
I never used Rom-Manager either.
I did install SD Speed Increase and increased the SD cache size from 128kb to 1024 kb.
Thats it.
Does this information change the previous recommendations?
No, just install EZ Recovery and follow the directions listed in one of the guides in the stickies.

Yes, if you have a custom recovery you cannot accept an OTA. The install will fail. You will have to Odin back to stock in order to take the OTA.

Thank you for the input.
There is a lot of information on this topic but its not easy to determine which of it applies to my situation. I feel pretty good about being able to Odin back to stock but I'm not sure I want to take the risk of doing that (probably not much risk) just to get the latest update.
I expect the best thing for me to do is decide to either 1) go ahead and install CM10 (I think that's the one I would want) or 2) go back to stock and stick with the Verizon software. I'd like to get Jelly Bean now, but I'm not sure its worth the risk. We'll see.
Thanks again!
If u use ez recovery and flash back the stock recovery u can then accept the ota just fine. As long as u haven't messed with any system files you are good. Then just re root it once ota is done.

Thanks for the info.
I have installed EZRecovery and it seems pretty straightforward. I'm still trying to decide if I want to go for a Jelly Bean ROM now or just wait.
I'll just keep reading until I'm comfortable that first, Jelly Bean will give me improvements worth the risk, and second, I won't brick the phone.
I have been fooling with computers since the 70s but Android is somewhat different and it will take a while to learn something about the architecture.
Thanks again.

If new I would flash an ICS rom first and get you a stable daily driver setup and backed up. Regardless of what you read all JB builds are buggy to an extent since they are all ports. The advantage of Android is as long as you have a stable Nandroid you can experiment with more advanced ports. Backup IEMI also and be careful jumping back and forth between AOSP and TW based roms. This is where the most problems come up. From what I've seen if flashed AOSP base it is best to Odin back to stock before going back to Touchwiz.

Or Twrp
I prefer twrp as it will allow you to name the backup from within recovery as well as some things cwm doesnt do.

Return to Stock

I'm sure this is discussed already but I can't seem to find it so if someone can help me or point me in the right direction.
I have a VZW GS3 that I have rooted, unlocked the boot loader and flashed CWM recovery. I then made a nandroid.
The main reason I did this was because I wanted Jelly Bean, and since Verizon is the slowest, I didn't want to wait so I installed custom ROMs.
Now that Verizon has released JB, I want to go back to my nandroid and then use the OTA firmware update service to upgrade.
Am I missing anything along the way that's essential for this to work?
Will the updated software re-root and/or relock my bootloader?
Will this automatically update the Baseband from my current VRLG7 to whatever the new one is?
One other thing, Will I still have CWM recovery after this happens? or will it revert back to stock recovery? or do I need to manually do anything to the recovery?
You're doing this to ultimately stay stock? Do you intend on flashing roms again or no? If you did a nandroid just after ONLY rooting and unlocking bootloader then restore it. Here's a step by step:
1) boot into CWM, restore your rooted, stock nandroid
2) Download EZ recovery, flash stock recovery
3) Wait for OTA
The OTA will relock your bootloader and unroot your phone. The JB OTA will also update your modem, and everything else, to VRBLK3.
One other thing, Will I still have CWM recovery after this happens? or will it revert back to stock recovery? or do I need to manually do anything to the recovery?

No, you will lose CWM if you do what I detail above. The OTA will fail if you still have CWM installed.

For the time being I intend on remaining stock, but I still want to root. Maybe once CM10.1 becomes stable, I'll go back to it, as of now I've had too many bugs with 10 nightlys and stable and 10.1 nightlys.

Nah I was just verifying to see if you modified any system settings or apps while on ICS TW. You should be in the clear as long as you reset CWM to stock recovery if all you did was root, unlock, then perform a nandroid.

No you do not, the nan will overwrite everything anyways. If you feel better then factory reset and clear caches, but it's not necessary.

I followed the instructions above and I'm back on my rooted TW.
When i try and update i get the following message:
Service Unavailable
To check for system updates, go to Settings > About device when service is available
What's wrong, how do i fix that?
searched around on google and a lot of people had the same warning error, multiple solutions were offered but none of them worked.
in the end, I ended up installing from odin completely stock unrooted, locked bootloader etc 4.0.4 (as f i want to return my phone to verizon) and once i did that it automatically updated to 4.1.1

Razr maxx hd os upgrade issue

I have a rooted razr maxx hd, and I received an upgrade notification last week. I used OTA rootkeeper to secure my root, and then upgraded to the latest OS. Once it upgraded, I used OTA rootkeeper to reinstate root.
I have had nothing but problems with the latest update. My phone freezes at least twice a day.
What can I do to fix this?

You said you reinstated root no? Update your super su binaries then install safestrap app and recovery. You can't go back to anything on the latest ota. what I'm suggesting is starting over with a fresh install of a new rom or a stock rom using safestrap. Your original install would remain untouched.

I tried to use Safestrap and tried two different roms, but they failed to install. Now my phone won't restart at all, seems bricked. What can I do?
I have tried using safe strap with multiple roms. One of them installed but wouldn't recognize my sd card. Another just made my phone freeze.
The one I really want to install is is just 4.1.1 with root, but every version of that I've tried to install immediately fails. Don't know if I'm just finding flawed files, or if it's something I'm doing.
What are my options at this point?

4.1.1 is not a rom, it is an ota... Im not sure what you are trying to do, but if you are on 4.1.2 OTA and kept root(restored root) and have safestrap installed you are good. There is no way to go back or downgrade to ICS with this latest OTA(4.1.2) yet. Once you are in safestrap I would create a back up of you stock slot, just hit boot options and make sure stock Rom is highlighted(it will also say Rom Slot: stock in red on top). Once that is done create a rom slot by going through boot options, rom-slot-1 and choose the size partition you want and then create rom slot. You can then restore the back up of stock slot you made before, just make sure you are on rom slot 1. Then wipe cache/dalvik/system/data, which are the top 4 options. Now you can install any rom which should be on your external sd card. There are some that are not daily drivers yet with things that are broken, but there are also fully functional ones. There are a couple other forums which have several roms that are only posted on those respective forums. You just have to look around.

I have done all of the above. I have 4.1.2 and saved and restored root. I have also installed safestrap. The problem I'm having is that every ROM I've tried to install is flawed (e.g. doesn't recognize my SD card, won't boot past splash screen). I really just want to go back to 4.1.1 OTA + root, which I found in the XDA development folder. But when I try to load it in safestrap using one of the rom slots, I just get an error. I've tried multiple versions, same result.

Like I said 4.1.1 is not a rom, it is a firmware and the file you are trying to install is a firmware upgrade. That post was for the jb leak, so you can download it when on ICS and upgrade to it while keeping root. To keep root you follow the steps in that post. Since you are rooted and on 4.1.2 now, you cannot go back to 4.1.1 on your stock slot. And there is no reason to try to flash a rom slot with a firmware upgrade because it will not work. So your phones main firmware is now 4.1.2 which can not be changed back to 4.1.1. If you need to sbf you will have to use the sbf file for 4.1.2 and that will restore your phone to stock 4.1.2 only and you will loose root for good. Or at least until there is a way to root on this latest ota which may not be for a while.
If you want a rom, it will say [Rom] in that title. Batakang, Inflicted HD and wWidow HD which are posted on this forum all work with no problems. Most of the others have either mounting(sd card), camera or something not working. And like I said there are some more out there on other forums that are fully functional as well, search... All of these roms are based off either ICS, or JB 4.1.1 and will work in safestrap on any rom slot except stock even though you have 4.1.2 on stock slot. Now if you are saying that even flashing roms which are listed as fully functional gives you an error then you are either doing something wrong, or have done something wrong when rooting.
Also if you created any rom slots, just delete them so you can start over. Create rom slot 1 and restore your back up of stock slot to it and wipe all 4 i listed above before installing the rom.

I'm on ota 4.1.2 + root with no problem at all, no longer lag with the stock launcher also.
At first the ota upgrade from 4.1.1 to 4.1.2 was failed, so i used the utility 1.1 to go back to stock 4.0.4, root, install voodoo ota, temp unroot, upgrade, restore root..
Hope it helps

You need to update to 4.1.2 using that factory fastboot files and then root again. I did the same and it made a noticeable difference in how my phone ran. I'll get you the windows link to the files. If you run Linux I'll have to upload what I've put together. Its based on mattlgroff HD utility but updates you to 4.1.2 and roots it.
