updated OP with:

Post-installation Notes and Issues

I'm aware that after flashing this, it is difficult to get back into recovery. I'm not sure WHY, but it's fairly consistantly a pain in the rear. However, I have found that following the steps in the following post seems to work (at least for me) 9 out of 10 times. (I was distracted on the 10th try, so not sure if it worked or not): http://xdaforums.com/show...6&postcount=14

Remember above I mentioned that when this package installs, it creates a backup of the old recovery? Well, it does that no matter what recovery was in place. So, if you install this package with a factory recovery, that backup will be of the factory recovery (which is probably what you want.) If you install this package a second time when you already have the CWM Recovery installed, you'll overwrite that factory recovery backup with a backup of the CWM recovery (which makes no sense.) I'd strongly suggest that after you FIRST install this package, you make a copy of that backup recovery image file (and full filename is displayed when it's created), and stick that copy someplace safe. Perhaps just rename it and copy it to your SDcard or computer. A good name might be "p6210_factory_recovery.img"

The Tab 10.1 could be difficult to get into recovery too.

Usually, the following works for me:

Press and hold VolUp

Press and hold Power until the screen turns on (this is slightly different from your instructions)

Release Power but keep holding VolUp until Recovery shows

Garys method of booting into recovery works fine. I'm just going to post it in linear format.

1. Press the power button and select Power Off

2. Press the volume up button (closest to power button) and do not release until the recovery screen is displayed

3. Press (do not hold) the power button

4. The static Galaxy 7.0 Tab Plus screen will display (possibly twice)

5. When the animated Samsung screen displays, press and hold the power button

6. The static Galaxy 7.0 Tab Plus screen will display

7. Release all buttons when the recovery screen displays.

This works every time for me
[Samsung Galaxy Tab Plus] speedrabbit:
Applied the zip using the factory recovery, no problem. Done w/o errors, root works great. However I'm unable to get into recovery, using the instructions in posts #14 or #20 (same thing).

I've tried it a number of times.. the first time through I see the animated Samsung screen, so then I press and hold the power button (already been pressing and holding volume up), and I just keep seeing the Galaxy 7.0 Tab Plus static screen come up, disappear, come up again, disappear, come up again, disappear. I've seen it go through a dozen cycles like that. If I release the power button (but continue holding volume up), it goes to the Samsung animation again and boots up.

Edit: Waiting for the 'low power charging' mode and issuing 'adb reboot recovery' does get me into CWM-based Recovery v5.0.2.7.
[Samsung Galaxy Tab Plus] otamctech:
I also get the same results. Will try the ADB method.................

---------- Post added at 08:42 AM ---------- Previous post was at 08:08 AM ----------

adb reboot recovery worked fine for me. Now to try a restore.
[Samsung Galaxy Tab Plus] garyd9:
Wow, a post that the author deleted all the text from!
[Samsung Galaxy Tab Plus] danomatic:
Just for consistency, I did do a factory reset before applying Garys zip.

I also reviewed the posted recovery method and it just now worked fine 6 times in a row.

I too am baffled at the inconsistency of the procedure.

If I find a better method I'll be sure to post.

EDIT: I've been playing around trying to get into recovery by many "wrong" ways. I did find out that I don't have to do anything other than simultaneously hit and hold the power and volume up button right when the animation screen displays. The static Galaxy screen then shows and then release when recovery pops up. So try this:

1. Power down the tablet

2. Power up the tablet (don't hold any buttons)

3. Right when the animation screen is displayed, press and hold both the power and volume up buttons

4. The static Galaxy screen will display

5. Release both buttons when recovery is displayed.

.I'm uploading a new version of this recovery that SHOULD fix the problems and difficulties getting into recovery. This version has the suffix of 20111209 and can be find on the first post in this thread. It's marked as "UNSTABLE" until someone other than myself confirms that it resolves the recovery difficulties.

Gary
[Samsung Galaxy Tab Plus] speedrabbit:
Bam. Straight into recovery every time. Not even a Samsung logo. Nice work gary, thanks! What was the fix?

(Loaded from 20111206 recovery)
[Samsung Galaxy Tab Plus] otamctech:
getting

cant open /tmp/sideload/package.zip using stock recovery to load.
[Samsung Galaxy Tab Plus] garyd9:
at what point are you getting that? Steps to repeat? Can you try to re-download?

(Just confused because I purposely put mine back to stock recovery just so I could test that it'd flash from there.)
[Samsung Galaxy Tab Plus] otamctech:
The zip is selected,

Recovery says locating update

Then it says opening update

Then i get the failure.

I have downloaded it three times.

Thanks
[Samsung Galaxy Tab Plus] danomatic:
Another confim for the the updated zip. It's almost impossible to NOT get into recovery now. As long as both the power button and volume up are simultaneously pressed by the time the animation screen shows, you will get into recovery. Works great.
[Samsung Galaxy Tab Plus] garyd9:
Okay, I'm trying to help you, but I need as much detail as possible, as I'm unable to reproduce the failure on my own tablet. This is on the GT-P6210 (wifi only) or SGH-T869 (tmobile)? What is the filename of the .zip file you are trying to install? Where is it located on your sdcard? You already said you were using the stock recovery - which version of the stock firmware? Is your tablet rooted?

The error you are getting is what I'd expect to see if the .zip file was corrupted. How the stock recovery works (as far as I can tell) is that it copies the selected .zip file to "/tmp/sideload/package.zip" and then attempts to unzip it into another temp directory, and then executes the edify script using update-binary in the same directory as the script. However, it sounds as if your recovery isn't even able to open the zip file - which is odd considering it seems to be working for everyone else.

Would you consider yourself comfortable with a shell prompt and is your device rooted? If so, send me a PM and I'll PM back with instructions on pushing the recovery manually. In the meantime, can you see if you are able to open that .zip file on your PC?

Thanks

Installed the 20111209 version from 20111206 recovery. Goes straight into CWM recovery with the pwr/vol_up buttons. Did a backup & recovery from ext sdcard with no problems. Great Stuff! Oh, btw, I'm using the latest version of the OS, KL1.

Edit: Plus I can boot directly to CWM recovery from Rom Manager!
[Samsung Galaxy Tab Plus] jayrads:
Works for me...

Another confirmation. Today's update (20111209) fixes my problems booting into CWM as well.

Thank you Gary!!
[Samsung Galaxy Tab Plus] otamctech:
Ok Gary. I was thinking hard about what was going on and it came to me that the only thing I was doing differently is what that my NEW 32G sd card cam and I was using that. I copied the file to a different card I had (16g) and it flashed just fine, and BAMM - right into recovery. Thanks again - u da man. Now can you explain to us what were the changes you incorporated to get this to work. Thanks again.

One thing that I did notice is that backing up to external reports cant open backup path. I am doing a backup to internal at this moment.

---------- Post added at 02:00 AM ---------- Previous post was at 01:17 AM ----------

The recovery sees the external card as internal,. So backing up to internal card is actually backing up to the external card. Have successfully (and proven) backed up and restored. Thanks again G.
[Samsung Galaxy Tab Plus] garyd9:
Glad to hear that it works for you, but sad to hear about the issues with your new microSD card. I have a lexar 32GB class 10 that, so far, seems to be working okay.

What I did - or had to do - was basically make a custom kernel for the recovery partition. Unlike most phones, this tablet actually has it's only "private" recovery partition/kernel along with ramdisk. That's going to make me supporting the 3G tab pluses a bit more annoying, as I don't have one to test kernel rebuilds on. On the other hand, I kind of have a free reign modifying the recovery kernel without concern that I might be breaking something in the normal boot process.

As for the internal/external thing - that's a known issue with that version of CWM. I've become used to it with my phone (SGSII), and I think it's better if I leave the bug "intact" as a known issue with that version of CWM. If it gets fixed "upstream", I'll pull in the changes.

I am concerned about the report of not being able to open a backup path when backing to the "built in" RAM (as opposed to the microSD card that's mislabeled as internal.) I'll look into that after I get some sleep.

(I woke up at about 11pm last night after 4 hours of sleep, determined to resolve the recovery boot issues. I did, but now that it's 20 hours later, my body wants a bit of a nap.)

take care (and goodnight)

Very smooth and sweet. No issues so far! TB backing up at present. Great job, Gary.

Hi Gary

I am new to the CWM Recovery, How can i put the factory Recovery image back after installing your CWM Recovery? Is the tab still rooted after loading the factory Recovery back? Just incase I need to turn the Tab back.
[Samsung Galaxy Tab Plus] otamctech:
To put it back to stock use odin3 and one of the stock roms in the development section. There are instructions in the thread. Its easy. The device will not be rooted if you revert to stock. Simple enuf to root again. Good luck.
[Samsung Galaxy Tab Plus] spyz88:
Can't get back into recovery...

I still can't get back into recovery in order to flash the updated version. I've tried Gary's instructions and then whoever's instructions put them into a linear order.

I also tried using Heimdall to flash the .img or the backup recovery .img I have but apparently its not compatible with the GT7P.

I also tried using various widgets from the market and rebooting to recovery through adb. Anyone have any other ideas?
[Samsung Galaxy Tab Plus] Brightxda:
Thank you. I want to know how to put the factory Recovery image back, not the ROM.
[Samsung Galaxy Tab Plus] mike216:
I think he meant by flashing the odin rom will put your stock recovery back but I'm not sure about this an interested to know the sure answer

I have a question, if we flash this recovery can we still update in kies as it seems there's an update every other day
[Samsung Galaxy Tab Plus] garyd9:
If you want to put the factory recovery back "just incase I need to turn the Tab back", then the ODIN method already described to you is your best choice, as it will restore the ENTIRE tablet back to factory new state.

Restoring the factory recovery will not "unroot" the tablet. Using the ODIN method will.

If you have something else in mind, please share. If you aren't comfortable with rooting, changing recoveries, using ODIN, etc - then the "DEVELOPMENT" subforum probably isn't the best place for you. I'm not trying to give you a hard time, but just being honest.

Take care

Gary
[Samsung Galaxy Tab Plus] garyd9:
<sarcasm> If you look on your keyboard, between the "M" and right-hand SHIFT key, there are (usually) two keys. The one with the little dot on it is a period. Please use it. I'm an older guy, and I can't read your mind. Without that little period to seperate two thoughts, I'm not sure where one ends and the other starts. (If you are posting with your android device, perhaps upgrade your keyboard to one that auto-inserts periods?)</sarcasm>

The way to use the backup generated with the installer package is with the following command (replacing <backup_image> with the name of the file of the backup recovery image.)

dd if=<backup_image> of=/dev/block/mmcblk0p6 bs=4096

I'm not mentioning what prep you might need for performing that command (such as getting shell prompts, permissions to write to the block device, etc) as if you don't already know these things, then using that command is VERY, VERY, VERY DANGEROUS. (I know what I'm doing, and I've shot myself in the foot a few times with it. For example, I can tell you for a fact that the kernel partition for a samsung galaxy S II phone doesn't work very well on the 7+ tablet.)

dd is a command that directly writes to a device. It doesn't play nicely, doesn't do any paranoia checks, and doesn't ask questions like "Are you sure you want to overwrite aimlessly and recklessly?"

Oh, and I can confirm that the KIES update doesn't seem to work very well with CWM installed. It doesn't break anything, but it just doesn't work. Instead, you get a dialog popup (in kies) with an oriental appearing langauge. Considering that samsung doesn't seem to be documenting their changes, I'd be paranoid about applying them anyway.

take care

Gary
[Samsung Galaxy Tab Plus] garyd9:
Coming changes:

1. fix backup to built-in memory

2. remove the .zip installer feature that deletes all existing backups. This will allow people to make a backup, ODIN back to factory for the purpose of doing a KIES update, put the CWM back in and restore that last backup.

3. remove the .zip installer feature that was making a backup image of the existing recovery partition. With the ODIN image existing, this really isn't needed anymore as a rescue.

Take care

Gary
[Samsung Galaxy Tab Plus] otamctech:
Um......... That was what i told you. Look for the thread for the factory images. There are not many threads to look for. Pick your device, download it, download odin3, and follow the odin instructions there.
[Samsung Galaxy Tab Plus] garyd9:
Assuming you have 'adb': plug your tab into your computer that has adb installed. Don't run KIES. Turn _off_ your tablet. (Press the power button for a couple seconds while it's on, and select the option to turn OFF the tablet from the menu that pops up. Confirm when prompted, and wait about 10 seconds for it to shutdown.) After it powers down, assuming your actually plugged into your computer's USB port, you'll see a battery icon/image on your tablet's screen. From there, you should be able to use "adb" to run "adb reboot recovery." This has worked with 100% success for anyone who hasn't been able to get into recovery any other way.

take care

Updated:

Changes for 20111210:

* A backup of the existing recovery image is no longer being made. I feel this is no longer needed, as an ODIN package is now confirmed to be working that people can use to restore their tablets to a factory state.

* Old clockworkmod recovery backups are no longer being deleted when installing this. If you are installing this or newer from my CWM recovery previous to Dec 9th, 2011, please manually delete all those old backups. If you attempt to restore them, please be prepared to download ODIN and a factory ODIN image, as you'll need it in order to get your tablet working again. You've been warned...

* The issue that was causing backups to the tablet's built-in storage to fail has been corrected.
[Samsung Galaxy Tab Plus] otamctech:
Good stuff Gary, i can confirm that backing up to the internal storage is workimg. Thanks
[Samsung Galaxy Tab Plus] danomatic:

[Samsung Galaxy Tab Plus] kodfish:
fantastic work! this thread right here has made me pick the plus over the 10.1, glad to see the beginning of what is sure to be a long and exciting community of dedicated hackers making use of the xyneos processor! good night tegra2, you will be remembered by many but missed by few. i will be getting my tablet from santa but as soon as it is unwrapped i will try and throw any mental resources i have to spare at rom hacking and maybe we will even see the start of ics since many people will be getting these!

keep up the hard work!
[Samsung Galaxy Tab Plus] speedrabbit:
Hmm. Just saw the note about the recovery not being compatible with firmware updates. I had 20111209 installed, and then applied the KL1 update via Kies. As far as I can tell, the firmware upgrade was applied successfully and I can see the new features of KL1 (like the Quick Launch). Booting into recovery takes me back to the stock recovery.

Do I need to be concerned? Seems like everything went fine, but the warning seemed pretty specific..
[Samsung Galaxy Tab Plus] garyd9:
Well, that's interesting! When I tried to do the update to KL1 via Kies, it popped up a few dialogs in some non-English language (korean, probably) and no update was done. I re-stocked the tablet and the upgrade went perfectly. Very interesting!

Did you use Kies to update?

To answer the question: no, you shouldn't be worried. You've made ME confused, but that's not a bad thing (and more common than I'd like to admit.) You can download the latest recovery if you'd like and flash it in.. it will no longer delete older backups, but if you restore one of those older backups, it'll revert the firmware update (or at least most of it.)

Take care

Gary
[Samsung Galaxy Tab Plus] garyd9:
Well, there's quite a bit more development working going on with the 10.1 (which is a much more popular tablet.) I did the recovery as I simply couldn't exist without it. I spend too much time tinkering with my devices to not have good and frequent backups.

the superior cpu will bring in developers within the next few months, 10.1 is simply obselete now which is a shame because i would prefer a larger screen that 7 inches... sometimes it is hard to be a geek, ignorance is bliss but knowledge is power! root and cwm guarantee an active community, especially once ics drops. if cm9 is not officially supported on this device i will maintain it myself. until then all i want is an oc kernel and i saw you said source is available! i wish i had device in hand so i could get going on this myself but come dec 31 its on and cracking!

cheers gary, know that your work is invaluable to me and others. i would have been upset and settled on a device i do not want in order to have the freedom to tinker had i not seen the doors already wide open here :)
[Samsung Galaxy Tab Plus] speedrabbit:
Yes, I used Kies to update, and only received normal english dialogues. I applied the Dec 10 recovery and will make a fresh backup.
[Samsung Galaxy Tab Plus] Entropy512:
The 10.1 has simply been out a LOT longer than the 7 Plus has been too...

The honest truth is that due to not having carrier mangling (at least on the wifi-only tablets), the stock experience of most Honeycomb tablets is quite good on its own. I ran stock HC 3.1 on my Tab 10.1 for ages until I ran into a media playback issue that caused me to go to Touchwiz (and I decided to go for a custom ROM then.)

I think long term, while the Tab 7 Plus isn't as popular as the 10.1, the fact that Heimdall will talk to the 7Plus is going to be very beneficial for you. Some developers (including myself) just don't bother with the 10.1 because it's quite usable stock and it's a bit of a pain to develop for due to no Heimdall.
[Samsung Galaxy Tab Plus] kodfish:
i think the price to performance ratio on the device is excellent and weither or not it ever gets OMGLOL levels of popularity like the galaxy nexus is unimportant. by this time next year i expect to see multiple mature ics roms on this tablet including cm9, and i expect it will perform near the top of the pack with overclocking and optimizations.

Thanks Gary,I certainly hope someone with some dev skills like you creates a bad ass rom for us one of these days.I thought the 7" tab would have a flood of people coming to get it considering the size and price not to mention its one of the fastest out there. Maybe I just need to be patient and grateful for what we have already but there is so much potential and room for improvement
[Samsung Galaxy Tab Plus] mike216:
Man I hope your rite! I love it but like I said there is so much more room for improvement. At least we have the first two obstacles out of the way 1-root,2-recovery (thanks Gary) and now CM9 would be a dream. I run it on my Nexus S, I would be more than willing to donate to that dev

Quick question. I installed the most recent version of gary's cwm version (thanks Gary!), but i got a couple errors when i created my backup. I got an error that said something along the lines of "no sd ext partition found" and something about the lack of another partition and that it could not backup the apps? Any idea what i may need to do to resolve this?
[Samsung Galaxy Tab Plus] garyd9:
Quick answer: don't panic.

Long answer: CWM Recovery, when doing a backup, looks for partitions and areas that not all devices make use of. A good example is the "sd-ext" partition I think you are referring to. Without knowing what the other message is/was, it's hard for me to answer, but I'm willing to guess that the other one was "android_secure" which is another location that isn't used on this device. When I ported this, I tried to do so making as few changes as possible to the "standard" CWM Recovery, and even left intact a "known issue" ("internal sdcard" referring to the external microSD card.)

Did CWM Recovery tell you that it completed? If so, it did. If not, it didn't. :)

Take care

Gary
