Header says it all... and if the answer is YES, then a link to HOW to accomplish that would be greatly appreciated...
Many thanks...
You would need to root, install cwm recovery, flash a rooted HC ROM.
@basballfanz: how to root the 9.2.2.3 Firmware?
From my experience, once you are on ICS, re-flashing Honeycomb via CWM does NOT solve the reboot issues (you'll have them in Honeycomb too). The ONLY way that I was able to return to a stable version of Honeycom was to NVFLash a stock honeycomb image and go from there. But, since you have a B90, you can't NVFlash, so basically, I think you're screwed at this point....
There is a whole thread about returning to honeycomb via CWM and still having the reboots, etc.. Search it out...

Don't think there's a way right now.
Can't you modify/use an ASUS Ota update package and use the stock recovery to 'Update' to HC. Reboot issues will still be there though.
Edit: as in when downgrading for razorclaw root etc

You can't downgrade on a stock tf.
The trick going from 8.6.5.21 to 8.6.6.19 to use razorclaw is technically an upgrade not downgrade. It was going from 8.6..5.21 to 8.6.6.19
Sorry I wasn't clear, I mean modifying a downgrade ASUS package to trick the Tf into Thinking that it's being updated.
Thanks for the version # clearup though X.x"
a simple rename do not work. Have taste it....
The tf see the update, reboot and start Update. But stoppt...
So what to do? Edit buildprob? Or what read the tf in Thema Update file ?
Get a hc package, unzip the ics package, delete and replace as needed. Probably need to edit build.prop too, and make sure the kernel flashes.
Or is a replace of the blob file the onky we need?
How is the chance of bricked?
Considering the kernel/os differences, higher than you'd want it to be, so I'd only do it as a last resort. Make a nandroid backup before doing any tinkering.
Cant do Backup without root. Thats why i want to downgrade...
Seems like a new method to downgrade from ICS to HC even for the non rooted users.

Can someone lead me or explain to me exactly what the s/n number means in terms of rooting and nvflashing. I have C30.

I think the real question here is why would you want to downgrade to HC from ICS? It's pretty well known that a full system restore fixes most issues.

Why? Because ICS is completely un-stable on ALOT of TF101's (if not all). Honeycomb was rock solid.

First letter:
B=2011 & C=2012 manufacture year.
Second letter/number:
1=Jan 2=Feb ect till Oct which is A(hex)
So your C3O was manufacture in March 2012.
Only different is the SBK
ASUS changed the sbk mid July 2011.

Hey all, just got my TF700 on Friday. So stoked.
I am about to root my tablet, but I want to make sure the current tools with work (sparkym3 and Debugfs) with the newest update. I would rather root the latest release than root what I have and use Voodoo. I have had issues doing that in the past.
My current firmware is IML74K.US_epad-9-4-5.26-20120720
How many update as I away from current? Will the current tools work with the most recent updates? Which method do you guys recommend?
Thanks!
I have not been able to get those two methods to work for me on the newest update. I think I am a rare exception, most seem to have success. I have even returned a tablet becuase of defect and the second would not root either. It wasnt a big deal because i knew i was going to unlock the bootloader and then i could install a custom recovery and rom and achieve root that way. If you are planning on unlocking I suggest you do a little more research in the NVFlash page because if you update from your current firmware that will no longer be an option. Just my 2 cents
(Imo) i would just root what you have now and use voodoo. Checkout the nvflash thread while your at it. ( doesn't work with .30 update, i wish i had noticed that before i upgraded to .30 )
Sent from my ASUS Transformer Pad TF700T using Tapatalk 2
I know it was mentioned but just for good measure... If you plan on unlocking at all make sure you do it before upgrading to .30 so that you can get nvflash setup for your device.
Sent from my Transformer Pad TF700T using Tapatalk 2
Is .30 the next update? How many update am I away from current?
I have some thinking to do, I wasn't planning on unlocking (at least until CM and AOKP officially support the TF700) but if NvFlash won't work on any other updates I may need to rethink.
And to be honest, I don't really see the purpose in unlocking. I ROMed my TF101 but ASUS does such a good job of only altering AOSP with small (and beneficial) changes I may just leave my Infinity as is. Especially if I have to stick with the shipped firmware and once I update NvFlash won't work. I guess I can always just flash ROMs without NvFlash though...
But my two questions above still stand.
One more question as this is the first device I have owned that had NvFlash available. What is the benefit of having NvFlash vs just CWM? Just protection in case I do something really stupid?
Sent from my EPAD using Tapatalk 2
You are one update away from the latest which is .30. (soon to be two) The debugfs root method will root you.
you should check out my thread on root and jellybean: http://forum.xda-developers.com/showthread.php?t=1908304
Nvflash allows you to flash anything even if the bootloader is corrupted or prevents it, it also allows you to downgrade when the bootloader prevents it e.g. .30 to .26. it is also required to flash custom bootloaders which is useful if someone develops a dual-boot bootloader. You can even relock and reunlock your bootloader with nvflash. If you don't plan on using non-stock fw though, stay locked so that you can get your updates and support.
Thanks for the help guys.
So what I'm thinking is just to root, unlock, and NOT flash NvFlash. It isn't terribly dangerous not to use right? I mean as long as I have CWM installed I am pretty safe unless I do something completely stupid right?

If you have .26 and are going to unlock, you may as well create your nvflash files. It isn't so much as flashing nvflash. Nvflash is already hardcoded in the tegra chip. You would just be creating the encrypted files needed to utilize it on your device. You save these in triplicate in case the worst happens. Unlocking is necessary for generating the nvflash files, but it voids your warranty and leaves you unable to recieve OTAs (you can still update manually using methods listed in the development forums).
I'm not explicitly recommending that you unlock, but if you do, it's best to do it on the .26 update, so you can get those nvflash files from your device.
So if I do install NvFlash can I still waiting install official updates from Asus by downloading them from Asus website?
I really want to try Asus's stock Jelly Bean ROM, so anything that removes that as an option is not for me.
Thanks for the clarification.
Sent from my DROID SPYDER using Tapatalk 2
you don't install nvflash. you use it to interface with the device's apx mode.
as for the official firmwares, you can still install those even if you are unlocked. you just have to do it manually.
Yup, you can just download the firmware zip from asus's website:
http://www.asus.com/Tablet/Transformer_Pad/ASUS_Transformer_Pad_Infinity_TF700T/#download
Unzip it once(it'l be another zip) and flash that in TWRP. (not sure if it works in cwm. I am biased but I definately recommend twrp:angel Make sure you uncheck flash recovery. reinstall recovery using fastboot because the update deletes it.

No, you need to unlock to take a bootloader backup, which you will not able to take OTA Jelly Been, however, you can download the new Jelly Bean from Asus website and manually flash it.
OK I feel like I understand now. There really aren't any downsides to setting up NvFlash (Asus warranty not an issue, I have Best Buy's super program where I can return the tablet even if I just scratch the screen if I want to).
My initial impression was that if I unlocked I would not be able to update any stock firmware period, and that if I set up NvFlash I could not move from .26.
If I understand correctly I just have to be on .26 to set up NvFlash, and can manually install official Asus firmware after unlocking.
Thanks for the help all! I am not new to flashing ROMs etc. but have never had the ability to use NvFlash.
Have a great night all!
Hey all, you guys have helped me understand things so many times in the past I figured I would pose this question. I just picked up my TF700 a few days ago, coming from the TF101.
So I have this bad boy rooted already and am about to unlock, I just want to make sure I understand everything perfectly before I void my warranty. I am looking to install TWRP but I see that it does not work with the JB update, would I be able to flash JB with it and then wait for a new version to come out?
So my process would be:
- Unlock
- Set up NvFlash
- Install TWRP
- Flash JB manually
- Chill on stock JB and wait for new TWRP version to come out.
Does anyone see an issue with this? My confusion stems from the massive amount of confusion others seem to have, and the fact that TWRP does not work with JB. Just want to make sure it makes sense to upgrade prior to a new version coming out.
Yes, I see that there is a new unofficial CWM version that is compatible with JB; however it is not a touch version and backing up does not work. I like TWRP much more and don't really see the point in using CWM if a new TWRP version will be coming out soon.
Thanks in advance all, you have no idea how many headaches you guys have prevented and cured.

Right on, seems like you have everything covered!
Don't forget to root while on ICS and save root with OTA Rootkeeper before upgrading to Jelly Bean. Then, after on Jelly Bean, re-install OTA rootkeeper and restore root.
I think there is a way to root even while on Jelly Bean now as well...

Yeah,this step is no longer needed for unlocked devices,he can flash the stock JB rom from Asus site and then follow this for rooting.
BTW @jtrosky,your device is 64GB or 32GB?I'm asking because you said once that you never had issues restoring a nandroid backup while i always had (64GB here).

Forgive my noobish question but your answer will help me out too,
I have just got my Asus a couple of days ago so, i have rooted my device, i don't understand how to do NvFlash that's why i keep my bootloader locked, no Jelly Bean support from TWRP yet another reason for not unlocking my bootloader.
So if there is no support for TWRP in Jelly Bean why do you flash it in the first place? Because i have read in your post that after you set up NvFlash (God knows how you do it, to my newbie eyes seems impossible) you install TWRP. Is there a spesific reason for doing it? What does it help you with?
Thank you in advance,
I looked at the NvFlash instructions and I am a bit confused as well. I am going to have a developer buddy from DroidRzr.com help me through it tonight, and once I get it installed I will help walk you through it.
As far as TWRP support goes, there will be a new release soon. They knew JB was going to break their current build (even putting a warning in the thread) but needed the source code for JB to fix it. The source code just came out yesterday (maybe the day before) so a new version will be coming soon. But you can always just use CWM if you want, I just like TWRP way more.
And you need to have either TWRP or CWM installed to flash JB, from your question it sounded like you are not aware of that.
Cheers!

Thank you for your reply mate, i am waiting for NvFlash walkthrough with anxiety. I hope you won't forget to post the guide in this thread when the right time comes, for all of us who have doubts about the NvFlash installation.:good:
As for the other matter i didn't know that TWRP or CWRM recovery is needed in order to manually update to the next firmware update.
Does what you said apply to any firmware installation, in order to manually update the Asus? (Since OTA doesn't work with bootloader unlocked).
And i am asking you that because i have read in a thread about this way of updating your firmware without the use of custom recovery, here it comes...
Alternative Firmware update Method
1. Decompress downloaded .zip file (it will be another .zip)
2. Rename it to EP201_768_SDUPDATE.zip
3. Format FAT32 the MicroSD card that you will be using for the update process
4. Copy the file to (the root directory of) your MicroSD
5. Insert it into the tablet
6. Shutdown (power off) the tablet
7. Power it on by pressing and holding VOLUME DOWN and POWER buttons simultaneously
8. When you see white text in the top left corner of the screen, release the buttons ^^ and press VOLUME UP button until you see Android logo and process bar
9. Wait patiently for 10 minutes or so
10. Enjoy!
Could you please tell me how to do an update with the use of TWRP or CWRM or tell me where you have read it because i am interested in
learning a new method of updating my tablet and also what is the benefit of using custom recovery in order to update firmware?
Thank you in advance and i am waiting for Nvflash guide,much obliged for your help
Of course . A lot of times when people write guides they forget that sometimes saying things like "execute this" can be confusing for some; execute in a command prompt or in a terminal emulator on the device?
Those instructions were for updating to JB via a workaround using the OTA update package before Asus released the official JB firmware. Now that we have the actual firmware (downloadable from the Asus support site) those instructions are uneccesary.
Now all you have to do is boot into CWM or TWRP then flash the update just as any other ROM:
- Wipe Data / Factory Reset
- Wipe Cache
- Wipe Dalvik Cache
- Format /system
- Install From SD Card (flash JB)
Someone please correct me if I have made a egregious mistake here .
Nevermind

For me I didn't do any wipes or formats at all and it worked fine. Kept all my data which was a massive bonus.
is such a thing possible at all with the tf700? i'm hesitant to root/unlock/flash roms until there is an unbrickable option out...
NVFlash works fine - it doesn't matter what version of Android your tablet is currently on. The only pre-requisite is that you have saved your TF700 "blobs" while you were on the .26 firmware or earlier. Once you have the saved the files, NVFlash will *always* work, regardless of the Android version.
If you've already upgraded to .30 or JB *before* saving your blobs with NVFlash, then you are stuck, there is currently no way to obtain the "blobs" needed to use NVFlash if you are past the .26 firmware before saving your blobs.
Hope that makes sense...

NO, the nvflash backup is for your device only.
I wonder whether the guys from Asus service use nvflash to rewrite everything in case the bootloader gets messed up as many users did with TWRP 2.2.2.0 or CWM 6.0.1.3?
I read somewhere in the forums that they actually have to replace the entire motherboard in this kind of a situation. Any truth to this?
Yep. All hard bricks with the TF201 got new main boards. No one can unlock either after they get their tablets back from RMA after this. There's a big thread about not being able to unlock on the prime forum.

So let me get this right...if the motherboard is changed than you can no longer unlock the device and port other OSs? Are they putting in a superboard of some sort that cannot be unlocked?
I find this hard to believe especially when you can get the unlocking tool from the Asus website. At least let's hope it's not like this, otherwise my tablet would lose some of its appeal.

No, but the problem is that after a motherboard exchange, the CPU ID doesn't match the serial number anymore. The unlock tool must contact ASUS to get the unlocking token (unique for each motherboard), and it fails if the CPU ID doesn't match in their database anymore. It simply can't get the right token anymore.
Ok....this makes a lot of sense actually. Let's see if the same thing applies to TF700. I'll keep you posted to whether I'll be able to unlock my tablet once it gets returned.
This is my second day at this, I just need something recent and relevant to follow, most tutorials start with having to install device drivers, which Iv done, and then installing Android SDK and fastboot, which is were the problems start, because even though some guides seem recent, once it gets to the SDK installation part, it redirects to a separate, older tutorial, that looks different from what I'm trying to do. I rooted my tf300t last year and it was was so much easier then this. I can get my tablet to boot with the RCK , Android, USB, Wipe option, but after that I'm lost, some tutorials mention unlocking the bootloader, some don't. I keep telling myself its not worth the headache, but as soon as I use my tablet, and see all the ads, pop ups, and bloated apps, I'm back online trying to figure this out.
Iv checked http://forum.xda-developers.com/showthread.php?t=1845377 and http://forum.xda-developers.com/showthread.php?t=2105949 but don't know if I'm on the right track, some assistance would be greatly appreciated.
If you are running jb then you have to unlock the bootloader first. You can download the apk from the Asus site. Once you do that, you can use the rooting guide in the general section to flash recovery, then flash root. Part 3 of this guide will help you. Its what I used and I've never looked back -

It shouldn't no. Every time Asus releases an update, I flash it with twrp. I lose root and recovery, but I simply put it right back on. The data you speak of is unaffected during this process.
