Hi there!
I'm a owner of a TF101 (B50) for month now, and recently I had the need to switch between multiple version of Android (as I'm an Android dev) : back and forth to/from Honeycomb from/to ICS for example, multiple time a day!
So, as I'm used to do with all my "Google's Experience" devices (Nexus S, Galaxy Nexus), I installed CWM on my TF101 to be able to generate nandroid. So far, so good.
I then downgraded my tablet to stock 3.2 using nvflash, installed CWM, and did a nandroid. Great, I now have an Honeycomb backup. Of course, at this point, I'm no more able to upgrade using OTA, so here's my first question :
1- Once CWM installed, how do you upgrade to the latest build ? Asus blobs are not compatible with CWM!
Then, since I needed an ICS nandroid, I reverted to stock 3.2 (using NVFLASH), and I let the OTA did the job for me - before installing CWM. Ok, now, I have both Honeycomb and ICS as backup : let's test that.
I rebooted in recovery, and then restored my 3.2 nandroid (from ICS, remember?). All I had once the job was done, was the android logo with an exclamation mark
After some Googling, I understood why : unlike my Google's devices, on the TF101, it seems CWM can't restore the boot partition. So, the bootloader used was the one for ICS, and the tablet failed to boot.... Here's my 2nd question :
2- Am I right? What guys are you suggesting to be able to switch easily between different nandroid versions ? Should I nvflash the boot partition by hand? If so, where to find a documentation on NVFLASH ? (I'm regretting fastboot )
Thanks for reading.
You can repackage the blobs so that they can be flashed from cwm. I think one roach's 3201 recovery is packaged this way, so you can take it apart to see how it all works. Essentially blobs are flashed through the staging partition. There is a blob tools thread in the dev section that has all the details.
If you want to go back and forth between roms, I think that nvflash will be your best bet. Rayman and bubble bee have the most info. Check out therenwebsite. It's something like androidroot.mobi? There is also a full backup and restore thread in the dev section that explains a lot of the details of nvflash.

I read, somewhere, that we can flash stock Asus firmwares using CWM ('update zip') by first extracting the initial zip (which contains another zip containing the blob). Is it true?

yes but you will loose root and cwm recovery. It's the easy unroot method.
Not a big concern. I can easily recover both root and CWM using the universal root method since I have a B50!
Thanks
Will you lose root/cwm even if you have OTA Rootkeeper installed?
You Shouldn't but no guarentees x)
I am on stock(P3113 rooted+cwm)...I am getting an OTA for 4.0.4 but for that i'll need to go back to stock recovery...Should i :
1) Flash stock rom n then take the OTA
2) Flash 4.0.4 through odin [ http://samsung-updates.com/device/?id=GT-P3113 ]
3) Flash stock recovery n then take the ODA.
I would like to go with option 3 cuz it will require the min. amount of downloading....But for that i need stock recovery...So what should i do n is there any other way??
On my 5113 the only thing that worked for me was to flash with Kies and then reroot. It was well worth it though.
There doesn't seem to be an easy way to get just the recovery and I think (not sure) that only Odin can unlock that partition anyway. There are some stock images in Odin format and I have been meaning to pick through them to see if I can find the stock recovery image, but since no one has posted such, I am guessing you can't.

But the problem is that i can't update vie kies...It keeps on disconnecting, so OTA is my only option n for that i need to get rid of CWM.
I am curious too, I rooted using this method, and have CWM installed.
http://forum.xda-developers.com/showpost.php?p=25480291&postcount=137
I guess I can just flash the stock image and loose root, upgrade, then reroot. Hopefully, someone will drop a stock, rooted and deodexed 4..0.4 rom for the P3113.
Also, I have not used Kies before, so I guess I don't even know how to flash the stock image for this tablet. Can anyone help with that?

To flash stock you'll have to use the stock rom n flash using odin,,, But i was hoping that there is way around it...
I've updated today my rooted P3113 to 4.0.4
This is the only way to upgrade rooted P3113 (with CWM), because the samsung official upgrade scenario doesnt works on CWM
1. Backup with Titanium
2. Wipe/factory reset with CWM
3. Download and unzip stock 4.0.4 firmware from here, then flash it with odin (PDA button)
4. Configure your device (now it's clean stock apps and stock recovery)
5. Restore your apps with Titanium
6. Install CWM and root - If you wish so (just as you installed on 4.0.3)

I would imagine this is just like the 5113. If you use Keis instead of the OTA update it works. Apparently Keis uses the USB instead of the recovery. However, a lot of people are having trouble getting Keis to stay connected. But I used it with no problems. Just reflashed CWM and rerooted as you say, but did not have to reflash to stock.
Just updated manually from 4.0.3 + Rooted + CWM 5.5.0.4 (GT3113)
Sorry too young to post links
Went very simple (10 minutes)
Returned to Stock Recovery: h://theunlockr.com/2012/06/02/get-samsung-galaxy-tab-2-7-gtp3113-back-stock
REBOOTED
Applied Update (not 4.0.4, not sure what it was)
Downloaded 4.0.4 from Samsung directly: h://samsung-updates.com/device/?id=GT-P3113
Unzipped to Desktop
Updated to 4.0.4 using ODIN (PDA)
REBOOTED
System applied update on startup
Asked me to select language, date, Goodle backup, etc
It loaded all existing Apps, Wi-Fi, etc automatically no TiRestore needed
Up and running, seems faster- smoother, new keyboard (old keyboard was good, this one is as good better for big fingers?)
:laugh:
Back to CWM & Root
h://forum.xda-developers.com/showthread.php?t=1722304
I downloaded the file from the Samsung site, launched Odin and updated. It kept all my apps and settings since I did not wipe. Flashed recovery, then rerooted, did not take long. If it gets yucky, I will do a factory reset.
Very helpful!
Very helpful guide.
On a semi-related note, I really like 4.0.4 it's certainly an improvement over the last and seems to have cured the stupid interface lag.
Ok flashed mine using mobile odin...no need to wipe data..

Your steps are so easy. I wish I could follow you on this, but I can't figure out how to revert back to stock recovery only. The theunlockr.com link shows how to completely revert the entire firmware. How do you revert recovery ONLY?
Hasn't someone made a .zip file that can be flashed with CWM? Why is it different than flashing a 3rd party rom?
I have a Samsung Galaxy Tab 2 7.0 (US Wifi+IR) P3113 [ROM Build Number: IMM76D.P3113UEBLH2] which is still 100% stock. I plan on installing a custom rom, but first I want to make a complete backup of everything.
I know I need to use a custom recovery (I plan on using ClockworkMod) and flash the custom rom. I don't have any problems with that part.
I also have all of my data already backed up. I plan on doing a full factory reset before installing anything anyway.
My main issue is that I want to backup the original stock ROM and all other partitions/images before making any permanent changes.
Since the device doesn't support fastboot I can't just "fastboot boot cwm-recovery.img" to do a temporary boot to backup the stock rom and recovery. All the instructions I've seen indicate I must first flash a new recovery image then boot the device from that. This would cause me to not have a backup of the stock recovery image.
I didn't see any backup options in Heimdall or ODIN either. No luck with Check Fus either.
Is there a way to backup the stock recovery image without flashing anything to the device first?
I have looked at sammobile at the P3113 firmwares, but I can't be sure those apply to my version (US WiFi + *IR blaster*) or would have the stock recovery image. Samsung Kies doesn't seem to have any updates or downloadable firmware for my tablet (it still has the ROM it came with out of the box) that I could extract the stock recovery for my P3113 (US WiFi+IR) from either.
I'd like a backup of everything so I could revert to 100% stock if needed. I also want to be sure I have the original recovery image and not some other version from a "stock rom" downloaded from the Internet.

Excellent way of articulating the issues and questions rbeede.
This is exactly what I have been trying to do too. I have searched the forums and google and haven't been able to figure out how to do this either. I was actually fixing to post the same questions myself and thought I should do one last search before I did, which lead me to this thread
I have the same tab and build (P3113 - ROM Build Number: IMM76D.P3113UEBLH2). As an android newbie I have been reading/researching for hours a day since Christmas and there is still a lot I don't understand. This is the first step I would like to take though and I intend on doing a full factory reset before installing anything too.
Can anyone help us with this please?
A. Want to backup the original stock ROM and all other partitions/images before making any permanent changes. Would like a backup of everything so I can revert to 100% stock.
B. For the same reasons as the OP, I also want to be sure I have the original recovery image and not some other version from a "stock rom" downloaded from the Internet.
I am happy to show proper appreciation for anyone who can help and once I get things sorted out and figured out I am willing to help others too. Thank you in advance
Backup
Howdy
You should find and download the stock rom for your device on the net. I myself do not recommend you to install custom rom as it can brick ur device.
For the backup:-
1. For the backup of your apps download this app (App Backup and Restore) from the play store. It can backup ur apps and then can also restore them back but also dont forget to take the backup of this app itself.
2. Connect your tablet/phone to your pc/laptop and then copy all the files in your SD card and Device and store them to seperate folders on your pc/laptop.
3. Now the backup of all your files is created.
According to my information you cannot backup your current rom you will have to download the stock rom from the net which you need and then fla**** in case of a mishappening or incase you wish to revert back.
Best of luck Happy flashing and a happy new year.

@kunalthakur - There isn't an official Samsung download source that one can use. Most of the other downloads I've seen have had the recovery.img modified to enable the backup in the first place. We want a trustworthy (verified no malicious software added) stock OEM rom/recovery with no modifications.
I have had some initial success getting the Samsung Kies software to attempt to download the current official ROM from official Samsung servers. I guess Samsung wants people to only download via Kies instead of offering it on their website to reduce the load on their servers and prevent end-users from flashing the wrong ROM because they didn't know what they were doing.
I will update if I have success getting a clean download.
If u are successful in flashing the original rom then notify me too as i dnt know of any such method. Oh by the way here is a site where you can download original roms.
downloadandroidrom.com
And by original I dont mean official.
Sent from my GT-P3100
That site didn't have a ROM for the US (Wifi+IR) GT-P3113
I did however notice that an official ROM update has just become available in Samsung Kies.
Version ending in LK7 (update from LH2).
I'm going to try to save a copy of the download for backup purposes.

Hello,
I'm using Galaxy Note 10.1 (N8013, UEALI3).
As our hardware and software are almost identical, I'll assume things will be the same for you and me.
How to create a full backup of your device, without touching anything?
There must be a way, but I also couldn't find it.
So, I found a way that just works as we expect.
To create a full stock device backup, with all images and partitions, without rooting, you'll have to....
Flash CWM! No, please, wait, let me finish...
When you flash a custom Recovery, it is actually not something permanent.
Once you boot your stock rom with stock kernel, your custom recovery is overwritten with the default one.
So, you can flash your CWM, and reboot your device immediately to it.
If you let your stock ROM boots, you are going back to stock recovery.
EXCEPTION:
- When you boot to CWM, choose "Reboot", you'll be given the following option: "ROM may flash stock recovery on boot. Fix? This can not be undone.". If you choose "Yes", you'll never get to stock again, even while booting stock rom.
So, flashing a custom recovery is actually very similar to "fastboot boot recovery recovery.img", as no permanent damages are made.
Finally, that's what you'll have to do:
1) Use Oding to Flash CWM. DO NOT Restart your device from ODIN.
2) Force turn off your device (press power button for > 8 seconds)
3) Boot to recovery (power button + volume up)
4) Make a full backup! In this backup, you'll have the CWM recovery.
5) Reboot your device.
6) Boot normally, and copy your backup from SDCard to your computer.
How to restore the stock I just saved?
1) Flash CWM again if needed.
1.1) If you want to get rid of the binary count, you'll have to make CWM permanent.. for a while.
1.2) Boot into CWM, go to Reboot Device, and choose "Yes - Make it permanent".
1.3) Boot your rooted ROM, download and execute TriangleAway.
1.4) Ok, your download count is zero.2) Now, go back to CWM and restore your backup.
3) This time, you have your stock rom + stock kernel, but still have the CWM recovery.
4) Boot your stock rom
5) Now, you have your stock rom + stock kernel + stock recovery.
I know this is not what you REALLY wanted (extract stock images, including stock recovery image), I wanted that to..
But this just works.
Let me know if I was able to help you.
Good luck!
So this is basically not possible then?
Hi guys,
Looking for some advice.
I previously had my phone rooted on 4.2 and everything was working great. For some reason I decided to install the OTA 4.3 update before reading here what it did. Before that though, I did a full backup through CWM.
Anyway, I'm now having trouble re-installing CWM to get back into recovery mode and go back to my backup.
When I try flashing it through Odin, it says Failed, and it seems like the phone blocked it because it is a recovery system.
Currently, when I boot up, I get the Custom logo, and when I try to go into recovery mode, it gets blocked and says it's unauthorized software, so I don't think I really installed the update right.
So, is there anyway to get CWM back on the phone to revert to my backup, or is there a way to flash the whole backup from a PC? The file is still intact on my SD card.
Thanks!

There is currently no way for you to flash CWM onto your S3 now that you have TW 4.3 VRUMCL1 update. If you want root, you will need to use Saferoot. If you wish to flash custom roms, you are currently only able to flash custom TW 4.3 roms via the use of SafeStrap. With Safestrap installed, you will be using a customized version of TWRP. Any and all of your CWM backups are incompatible and wasting storage space. Links to everything I just mentioned are contained in our TW 4.3 discussion thread.
Note that when you use Saferoot to gain root access, the tool is in the S4 section however it states that there is nothing in the tool itself that is S4 specific and that it should work on other 4.3 devices. It does work. Search in the discussion thread or in Saferoot thread to see confirmation.
Edit: to work around the Yellow triangle issue, you'll want to use ThePagel's soft brick thread.
Edit #2: Also, being that you are on TW 4.3 update, you absolutely can not downgrade your firmware using pre-existing Odin stock images. You can only use the official, VRUCML1 tar that is about 1 GB.

Hello community,
I was given the device last year and had been fairly satisfied with the performance of it. However, it has gotten laggy over the past couple weeks and a friend suggested to root and flash a rom on it. So, without any prior knowledge, I have been doing some research and browsing through the threads on this forum. I can see that there are guides but was very unsure if the methods would still work because I have noticed that most of them were last updated/edit a while ago. I know I shouldn't use the word 'latest' for doing this to a tablet that is fairly old in the market. However, it would be very helpful if someone can point me to some 'proven to work' or 'trust-worthy' guides of rooting, flashing recovery, and rom.
Also, just out of curiosity, please recommend which recovery and rom a first-timer should use if possible
try these roms.

I was looking in the forum and someone said that I would also need to unlock the bootloader? If so, how do I do that?
Also, is there a difference between kingroot and towelroot? I saw a post in the forum here saying towelroot is fast and easy to root the tablet.
Not much difference.
Actually there is not much difference between kings root and towel root....towel root doesn't need a PC...but I have never used it so I can't assure you that it is safe.
And coming to the boot loader I don't know much about it but I didn't do anything like that before flashing a rom or rooting my tab2....
If you want further assistance about the boot loader I can help you with that..

it is not necessary to unloack bootloader for tab 2 as it comes with a unlocked bootloader from stock.

Hey, it's been a while. Honestly speaking, when I first posted this thread, I didn't really have enough time to do the things so now I am finally back and trying to do it. So far, I know what recovery and rom I'm going to use with all the files downloaded and ready. Though, currently, I am still at the pre-root stage. I have read up things about kingoroot and not sure if I wanted to use it. So I looked around on the forum and wonder if Odin is still a working solution. Reading on the steps and guides, I was wondering if I need to have Kies installed?

Kies is not needed as it never helped.
You can depend on odin it is your only saviour when you are in trouble.
I think rooting with kingroot is easy as it is just connecting to your PC and cick the start button.
So just notice me when your ready.
And there is also one good news...?
Tab 2 has got marshmallow.

I have rooted the tablet. I did it with odin and twrp with flashing the updatedSuperSU zip folder.
I have tried flashing the CM12.1 rom yesterday but resulted in a boot loop. So for now, I'm just rooted and on stock rom until I or someone can find out what was the problem. I have read about the discussion with marshmallow but it seems to me that the project isn't really stable yet. From what I have researched lately, can I assume there's issue with the p51xx line of tablets? Because I saw many people having problems with p51xx and most people with the other tablets aren't having any.

You first must update your tab to jelly bean bootloader, before trying out newer roms.
Or perhaps flash stock jb firmware with odin
Whatever you choose, both is ok.

The first thing you do, is take a nandroid backup, it's very important at every step, unless you are really ready to risk. It's better to have it.
Next Read through the rom threads, clear your mind and your tab too. You must format data.
Stay on twrp 2.8.7.2. Don't go to the latest one yet.
Flash rom, wait, it will boot up.
Every tab behave differently with every rom, sure you are going to face soft reboots, on some roms it will be a lot, on some it will be less. I would suggest you try both LP and kk first.
Remember, it's better to keep this tab updated than to stay on stock. This tab 2 series has a emmc bug and staying on stock or jumping back is a risk too. I have been on kk and lp. They both have kept this tab running great and away from that bug.

Do I have to unroot first? Do you have a link to making a nandroid backup?
Edit: Oh, I looked at the link you included and it said that if I am on stock jb (4.2.2), I can skip the update bootloader part..
When you flashed the new rom, did you do a factory reset (wipe data)?

Yes, that's what I meant too, if you're on jb already, you are fine. You don't have to unroot. For making a nandroid backup, use twrp recovery, there is an option for backup, select and backup all from there, if you get into bootloop or any other problem, as long as you can get back to recovery, you can restore from there. Most rom comes pre rooted.

Did you clear dalvik cache in recovery before flashing rom?

Yes, I cleared the top four options in recovery, and formatted data before flashing.

That's what I did. Let me just briefly summarize what I have done:
used odin with twrp
booted into recovery and made back up
cleared dalvik, cache, system, and data, formatted data
flashed update supersu, booted into system and checked root with root checker
rebooted into recovery, cleared dalvik, cache, system, and data, formatted data again
flashed cm12.1 and gapps, rebooted but ran into bootloop at splash screen
rebooted into recovery and restored back up
So I'm rooted and on stock 4.2.2 currently.
