A problem currently exists with newer Xooms when attempts are made to flash ClockworkMod 3.2.0.0 (R4c) (CMW) into the Recovery partition. This issue has been mentioned in several threads with no resolution to date.
This is what the problem seems to be:
- Fact: There was no problem flashing ClockWorkMod (CWM) to older (earlier versions than 3.2.1).
- Fact: The problem occurred with attempts to flash later versions of Android, e.g., 3.2.1 following update via OTA.
- Fact: The OTA has an incompatibility with CWM. Joe Ferreira identified the problem as one of the following files being present that will prevent CWM from working:
/system/recovery-from-boot.p
/system/etc/install-recovery.sh
- Fact: The proposed fix involves reverting to an earlier version, i.e., 3.0 and updating to 3.2.1 via OTA. This fix is yet unproven.
- Fact: Owners of newer Xooms are being prevented from achieving root because of this problem (including myself)
To summarize:
1) Recent OTAs which bring the Xoom to 3.2.1 are incompatible with the ClockworkMod 3.2.0.0 (R4c) image (CWM)
2) Once flashed CWM is inaccessible.
This is the problem that needs to be resolved.
Note: Epic118 has suggested reverting to 3.0; updating via OTA to 3.2.1; and rerunning Xoot. I don't understand this since attempting to flash CWM on 3.2.1 updated via OTA will repeat the same issue. Perhaps EPIC118 can provide clarification.
Does anyone have a solution/fix to this problem?

How about reverting to stock 3.0.1, then OTA updating to 3.2 and then rooting/flashing recovery and custom rom/kernel. I would think the issue is with the 3.2.1 OTA update itself.
I'm not completely sure I understand but if u can try this,
Download the universal root update zip and put it on your xoom
Flash clockwork through fastboot and then reboot into recovery, don't let it boot or the install recovery.sh will delete clockwork!
Flash the universal root.zip and boot up and use a root file manager to delete those two file and clockwork should stick through a reboot

Hi
I have a UK Xoom and I am interested in putting a custom ICS on it. I have read through all of the pages of the excellent guide to unlocking and rooting etc started by okantomi. Fair play to all involved, its a great source of information.
My Xoom is showing 3.2 as the current version. When I bought it a few months ago it had 3.0 installed. I updated OTA to 3.1 and more recently to 3.2. I then got a small update a few weeks back but Android version is still showing as 3.2. Am I good to go ahead?

I'm not sure what update (after the 3.2 update) added the security "fix" that seems to cause the problem, but you might as well try to root. If it doesn't work, at least you have a potential work-around, but hopefully it will be fine.
Good luck.

Cheers, I went ahead with it and it worked out no problems, unlocked, rooted and I can access recovery. Ill post the details in the guide thread to keep everything in the one place.
Superchilpil,
Thank you for your reply.
There are a few points I don't fully understand.
You indicate,
Flash clockwork through fastboot and then reboot into recovery, don't let it boot or the install recovery.sh will delete clockwork!
Click to expand...

1) Should I reboot into recovery using fastboot or simply reboot the Xoom using "Vol+ and Power"?
2) You indicate, "Don't let it boot". I don't understand; if I initiate a 'reboot', it reboots. How can I prevent it from rebooting???
This is the code I will use to flash Clockwork:
adb reboot bootloader
fastboot flash recovery recovery-Tiamat-R4c-100611-1150-cwm.img
Click to expand...
Click to collapse
What code should I use to effect your suggested approach?
One last question. The objective of this question is to understand if I can simply flash the "Universal Root Update Zip" to obtain root using the stock Recovery Mode, then install ClockworkMod Recovery; then remove one or the other of two problematic security files which are currently causing a problem. This will theoretically resolve the "Green Bot of !" issue Xoom users with 3.2.1 are currently experiencing.
After unlocking the bootloader, is it possible to:
1) Flash Update.zip (from the MicroSD card) using the stock Recovery Mode
2) Flash ClockworkMod Recovery through fastboot
3) Obtain root from this procedure
Thank you in advance.

by not letting it boot I mean don't let it boot into the rom, and both of those methods u stated will work just fine to reboot
And flash it using whatever method you desire, but I forgot to mention that you may need to flash clockwork again after you boot and delete those files because the install recovery.sh obviously flashes the stock recovery and the point of my method is to keep a custom recovery on your device
I know for a fact that the stock recovery mode won't flash anything you will find here in the forums that I know of

Correct, the stock recovery requires that the zip files be signed with keys that only the manufacturers have access to. This is the whole reason why we have to flash a third party recovery to begin with.

I'm getting more and more confused the more times I read this.!!
I have done the update then unlocked to find I now have the green bot!!!!!
Someone please send a simple step by step with some file links to revert back to stock 3.2!
Thanks
I was HC stock, locked, unrooted, had accepted all OTA's - and therefore had the problem with the 2 files mentioned in the OP. I updated to ICS just fine. In order to root, I did the following (the differences from the standard instructions are underlined)
unlock
flash recovery
boot into recovery
root
then while still in CWM, no reboot, but instead:
adb remount
adb shell rm /system/recovery-from-boot.p
adb shell rm /system/etc/install-recovery.sh
reboot with CWM
Only had to flash CWM once.

Thanks. This makes a lot of sense. I would like to edit my rooting guide and give this procedure as the preferred approach. Is there anything you would want to add to it?
Just as a Fyi, these files are on all Android os, not something new. You can also flash an insecure boot image, and it will stop these from running.

Hi,
First - thanks for your rooting guide - I used it with the exception of my underlined steps which were a synthesis of what I saw in a few other places.
Nothing to add - except perhaps really emphasize to keep the USB cable connected, and after rooting, do not reboot, stay in CWM, and use adb to run the 3 commands. You wrote a very detailed guide, so know you'll do a great job writing the expanded version of my short underlined additions. As you obviously know, many of the less technical users need a more detailed explanation of my underlined changes.
Thanks again for the help your guide gave me!

Yes, I saw them mentioned re several devices as I googled.
But - are you saying they were present in stock Xoom HC? Everything I've read says they were added in the 3.2 OTA, since people who are on 3.1 don't have these files to deal with.

These are a _function_ of the OTA process. When there are kernel or recovery updates required, the stock recovery partition requires patching, hence these files.

Thanks, that helps explain what they are. So, if an OTA (like 3.2 apparently) wants to patch/replace stock recovery, those are the files that do it on next boot. Would be nice if they deleted themselves when done (from a hacker's POV), but for people running stock, I guess it makes sense for the OS to check the recovery partition at each boot and overwrite it with stock recovery if needed.

Sure - glad to.
Yes these files were on the stock Xoom. Infact it helped us get some of the dumps. We would flash cwm, then dump, then let the OS rebuild the recovery. We then flashed cwm to boot and dumped the stock recovery.

If using the wrong version of custom recovery vs bootloader can brick your device. The best way to approache this is, first upgrade your device to the latest JB .25, then unlock your device, then use fastboot to push your latest twrp recovery (2.3.3.0), then flash custom rom. Pretty much straiht forward without risk.

do i still need twrp installed or do i use fastboot for that?.. also i had to downgrade to 9.4.5.30 to root it first, should i need some kind of root protection before upgrading back to JB?

You don't need to root if you're unlocked because all custom roms are pre-rooted. Maybe this will be clearer;
Let pretend you're on JB, if you are on ICS, just use OTA upgrade to JB.
1. use Asus unlock tool to unlock (the tool will work with ICS or JB and very safe to use)
2. Use fastboot to push TWRPcustom recovery to your device
3. Boot into TWRP to flash custom rom (now have custom rom and rooted).
Done.

Yes, "fastboot flash recovery ... " installs a recovery.
I rooted mine when I had ICS and used OTA rootkeeper to OTA to JB to keep root. Unlocked it then used Goomananger (required root) app from the market to install TWRP. I like goomanager as you dont need to hook it up to your pc and was pretty easy. If you're already rooted I would go this route to install custom recovery.

I was just as hesitant as you are. Took the leap yesterday and I am VERY happy I did. CROMI turns this baby into a whole new experience!
Just follow the instructions in this thread:
http://forum.xda-developers.com/showthread.php?t=1833212
Read it, follow all the links, read it again and when you feel you really understand the process, follow it step by step.
The whole process turned out to be a breeze - especially compared to the trepidation I had about this

Best rom is CleanRom version 3.2.1.
ok.. well it seems i have twrp installed just fine now, used the fastboot method... im going to try cleanrom a bit, and try out the ubuntu LXDE rom as well, ill try cleanrom first
it looks as if everything was successful, and i made it past the stage that caused a brick before, so i would say im in the clear now, tried clean rom, pretty cool you can choose your stock launcher but i really want to experiment with ubuntu on it as well with a mouse and keyboard, see if i can replace my netbook with this
I had my phone bootloader unlocked, CWM loaded, and rooted. I decided I didn't really need root and was messing around so I took the VZW update which, of course, required me to flash the stock recovery.
Well, I wanted to play with the new CM 10.2 so I went to flash CWM back on using mattlgroff's utility and while I don't receive any errors and it reboots the phone, the stock recovery is still there.
Any way to flash a recovery or am I hosed? I thought it was only motochopper I couldn't use on the new VZW firmware.

Flash recovery manually.
Turn on USB debugging
Open the folder that has the tool files. Find the one that had adb, fastboot and aapt. Go up one folder. Hold the shift key and right click the folder that has adb etc. There is a option in the right click menu that says something to the effect of 'open in command prompt', select it. in the command prompt type: adb reboot bootloader Hit enter.
Copy the cwm img file into the folder with adb and fastboot. Go back to the command prompt. Then type fastboot flash recovery <name of recovery>.img Hit enter. If it doesnt reboot type: fastboot reboot Hit enter.
Enjoy.
Tip: when typing the name of the cwm image type the first few letters then hit tab to autocomplete the name.
Unfortunately, while the commands went through without error, it still has the stock recovery.

When you go into the bootloader it does, in fact, say you are unlocked?

I was using mattlgroff's utility and the first time I tried CWM it failed. I didn't have my phone rooted, but I had the bootloaded unlocked. So, I just rooted the phone and reflashed CWM and it was fine. I think that same utility has the old software on it, so if nothing else, just flash the old software, root, and then install your recovery.

You can flash back to the last version then root. Then you can try flashing CWM or TWRP.

You shouldn't but these phones are a bit wonky when it comes to that sort of stuff. For example you dont need root to unlock the bootloader on any other phone except this one.
What does the stock recovery even look like? Ive never been there. After flashing the recovery how are you getting to recovery? Are you using the terminal or command prompt on your computer or are you holding the up/down/power combo the arrowing down to recovery and then arrowing up?

Ive found the solution to this if you still haven't...
You need to have root. How you get that is up to you. I flashed back to the last rootable OTA, rooted, used voodoo root keeper to backup root, then took the OTA and restored root with voodoo. Once I had root again i used Root Explorer to rename the file called recovery-from-boot.p in /system . Then I booted into fastboot mode and flashed the recovery like normal. That was it.
Hi guys,
I'm a total noob regarding ROMs, root, etc..
My Infinity is getting really laggy, and I really need to bring it to a new life..
I was looking for an ideal CMInstaller situation like i used on my Galaxy Note N7000.. This little app is great cuz it does everything for us and noob users like myself don't need to be afraid to brick their devices..
Is there any really easy solution like this so I can safely flash my TF700?
TIA.
I think the answer is yes and no
I run CROMI-X on this tablet, but recently I download the latest CM and the link provided kept bouncing me to the Playstore to dl an installer app. I prefer to use my recovery, so I did not use it. But that's probably what you are looking for.
The thing is, on this device first you need to unlock the bootloader and push a custom recovery to it before you can even use an installer app. You also need to make sure that you have the correct bootloader installed before you flash the CM rom.
Check out the CM thread in the Development section.
CMInstaller so far is only compatible to most common Galaxy and nexus devices, and htc one.
http://wiki.cyanogenmod.org/w/CyanogenMod_Installer#Supported_Devices
I am honestly afraid to flash my device without assistance because there are so many things to do and none of it seems easy.. I'm bootloader unlocked running stock 4.1.2, and the steps needed to take scare me..
1 - update to stock 4.2.1 (according to what I've read..)
2 - Root
3 - NVFlash
4 - Custom recovery
5 - Custom ROM
I don't even know if these steps are in proper order, but seems that so many things could go wrong.. Could you help me doing this easily and problem free? I need to do something to take full advantage of my TF700.. It clearly isn't working properly on stock.
Thanks.

Hi, I read the tutorial and I already have some questions even before i start..

- Where's NVFlash? If NVFlash avoids bricking my device I believe this is a MUST have if I intend to grow and experiment different recoveries, kernels and ROMs.
- My device FW ver. is 10.4.4.18, do I need to update to 10.6.1.14.10 in order to continue, or can i do it from 10.4.4.18 and still take advantage of the loophole Motochopper exploited to gain root on this device?

You don't need to be rooted to flash a custom ROM. You can root from 14.8 as you don't need to go to 14.10. If you are on 10.4.4.18 you are on a really old boot loader for 4.1 and will need to upgrade if you want to unlock and flash the latest ROMs.

- My device FW ver. is 10.4.4.18, do I need to update to 10.6.1.14.10 in order to continue, or can i do it from 10.4.4.18 and still take advantage of the loophole Motochopper exploited to gain root on this device?
Thanks.

Jeez - where did you dig up this version? I believe that was one of the first JB versions? Yes, Motochopper should work, but: Why root if you can't use Goo Manager to get a custom recovery installed? If that is your goal....
Yes, you can just root the stock ROM, but it does not give you that many options to improve the performance of this tablet. And any custom rom is rooted - so why bother?
To have NVflash is great and a wonderful reassurance and I do flash with greater abandon since I got them, but generating the blobs was the most stressful procedure in my limited flashing experience.
I don't know how comfortable you are with using cmd and fastboot - but I sure was glad to have some experience with flashing recoveries and such before I started it!
Generating the NVflash blobs involves flashing a bootloader and recovery build just for that procedure, so you need to know how to flash those in the first place (and how to flash back to your daily driver recovery/bootloader afterrwards).
There's nowhere for you to go without a custom recovery. Start with that.
I have no idea if the recovery most of us use (TWRP 2.6.1 or 2.6.3.1 - both are fine) works with the BL you currently have.
So I would update to the latest firmware, fastboot TWRP and then install CROMi-X.
You can dive into getting your NVflash blobs as soon as you have TWRP installed - that's up to you.
Edit: sbdags was faster - as usual
So there you have it: You have to update your stock firmware before you install TWRP
Wow guys.. This is why i never flash anything since bada on my Wave..
It's all so technical, confusing and intimidating.. God!!
Ok. I really need to start understanding this, so, if I got it right, I don't need to root because the custom ROM is already rooted.. Good!
Now the hard part. Please be patient and gentle, explain me like I'm 5 yo child.
- If I understood correctly first thing is upgrade FW, but to which FW should i upgrade? 10.6.1.14.10 or 10.6.1.14.8? If custom ROM is rooted, does the FW matter or not?
- Next comes recovery. Again, which one should I choose? (sdbags your opinion would be really important for me here, considering CROMi-X 5.2.2 is developed by you and the ROM i chose)
- I think I'll leave any ROM questions for later, after i finally understand these first 2 steps.
Also, regarding NVFlash, what the bleep is blobs? I'm comfortable with cmd but never used fastboot.
Thanks again!

It does not matter. As long as you upgrade to a 10.6.1.x version, your bootloader will be compatible with TWRP 2.6.1 or 2.6.3.1 - see below.

sbdags is currently recommending TWRP 2.6.1. That is the version he included in the bootloader/TWRP package he provides in the OP (Original Post) of the CROMi-X thread.
To elaborate: In flashing custom roms the most important aspect is that you always have a compatible bootloader/recovery combination. You use your recovery to flash roms, bootloaders, kernels, wipe all or part of your SD card - the works.
If your recovery gets corrupted but you can still boot into the bootloader, you can install a new recovery using the fastboot protocol (which provides low level access from your computer). If your bootloader gets corrupted (and the most common cause is the wrong recovery) and you cannot boot into recovery, NVflash is your last chance to recover the tablet because: no bootloader = no fastboot access.
The easiest way to get a current bootloader in your situation would be to upgrade your stock firmware. The risk for something to go wrong is close to negative 1
Then you would download TWRP 2.6.1 for the TF700 from the Teamwin website and use the fastboot protocol to install it to it's proper partition.
Risk level is very low if you can follow the instructions in my little tutorial or in the Minimal ADB Fastboot Tool thread.
Once you have TWRP installed (and you tested that it's working) you could - and this is totally optional - flash the bootloader/TWRP package from sbdags OP. Just to make 100% sure you are on the correct combo.....
Also, regarding NVFlash, what the bleep is blobs? I'm comfortable with cmd but never used fast boot.

A blob is a file - better: an image. Binary Large Object is the origin, I believe. For a technical explanation don't ask me! Go here:
http://en.m.wikipedia.org/wiki/Binary_large_object
If you look into the Asus firmware zip file, inside is a blob and a meta data file (if memory serves me right). The blob is the system image.
What if while you are flashing a firmware and your power supply is reaching 0%, could it be a high risk? :silly:

The Asus blob actually contains the system image, kernel, recovery, bootloader and partition table.
Ok so I just recently got my hands on a Nexus 5 which I rooted with CF Auto Root and relocked the bootloader with Bootunlocker for security (I'm guessing I should unlock before the update). I see reports surfacing of a possible 4.4.3 update in the near future. So before that happens I want to figure out the best practice for updating a N5 with CF Auto Root. It stands to reason I'll do a full backup so that's a given.
I'm not new to rooting. Done it a few times. Just haven't had a device that gets regular OTAs in my country so it hasn't come up.
Is there a way to update so that root is preserved? Obviously I'd like to keep the process as simple as possible but if I have to work from scratch it's not the end of the world.
As I understand it, you can do normal OTA as long as it's stock but you lose root. In that case, does the OTA relock the bootloader or will it stay unlocked? Which then basically means a new root which wipes the device.
Or perhaps it's better to ask what the best procedure for updating a stock Nexus 5 with CF Auto Root.
Everything that you have ever wanted to know about OTA can be found here http://forum.xda-developers.com/google-nexus-5/general/info-nexus-5-ota-help-desk-t2523217
Ah thanks. Appreciate it.
generally no, after ota you lose root. but there are apps that will save your root so that you keep root after an update.
I've been looking at Survival Mode in Super SU and RootKeeper but there seems to be some question as to their success.

ive never used any since i dont ota, i update my custom rom as soon as its updated, but ive heard of success with rootkeeper. but it doesnt matter, it literally takes 3 minutes to root a nexus the right way(via fastboot).
Yea, I should use fastboot in future.

The stock Android OS update will not relock the bootloader. So, once you apply the OTA.zip file in recovery, all you will need to do is reflash the SuperSU, and you are done.
(Note that depending on your system status, you may not be able to apply the OTA.zip directly - for instance, if you have updated/deleted system files etc, in which case, you will first need to go back to stock - refer to the link that @mistahseller provided for details about how to go back to stock)

you would need to flash a custom recovery first, then supersu in your custom recovery.
Thanks everyone for the responses.You've made everything much clearer.

Good point. I assumed that op had installed a custom recovery when he rooted, but that is not always the case.
Ok so I'm going to sideload myself. Been a while so I just want to confirm the process so I don't screw up.
I'm using TWRP
Obviously I'll do a NANdroid and probably Titanium as well.
1) Unlock bootloader with Bootunlocker
2) Connect device to PC
3) Boot into TWRP recovery and go to Advanced > ADB Sideload
4) type adb sideload update.zip (or whatever I call the file)
5) reboot device and check if it's working
6) reboot to recovery and reflash superuser.zip
I think that's it. Is there anything else I need to be aware of? If I'm right it should then be updated, rooted and in the same state before I updated.
I am in the same situation. I am currently rooted with a unlocked boot loader. When 4.4.3 comes along I plan to upgrade it. I have only rooted and have CWM no custom ROM. I know o cannot perform a OTA update. So do I copy the update zip (4.4.3) and just flash in CWM? Is this correct, and if so do I lose root/ boot loader. Thanks. I have read the thread above but do not understand

Flash stock system.img and flash recovery.img and then do the update.zip from the stock recovery..
If you don't want to flash, then make sure you have removed all the modifications you have done to system apps. If you don't remember then I would certainly recommend flashing stock images...
