I think you have a few options:
- find a flashable zip that installs the stock firmware
- make a flashable zip yourself to install the stock firmware
- use nvflash if you have a low enough serial number
- flash the stock firmware using the staging partition
- there might be a way to use asus-backup, but I haven't tinkered with that.
The first two options usually require the command line and blob tools, although some of the rom cooking tools might work. You could probably mod one of the asus stock roms to flash via recovery.
The nvflash option requires the blob tools and nvflash.
The staging partition option can be done via terminal, but can also screw things up quickly. You'll also lose recovery unless you use the blob tools.
You'll have to mod the stock firmware to be pre-rooted if you want to keep root, which will require slightly more advanced android-fu.
All of these options would start with the EU/WW asus stock firmware. You'll just be modding it to install to your liking. My choice would be a DIY flashable zip or the staging partition, but that is just me.
Do you want to keep root or recovery or just go bone stock? Does nvflash work?
so many questions lol. But that just means alot go look up first. This sounds cool. Thank you.
Why go with nv flash? I only ask because ive always used cwm. But iguess i was rooted too.
Lets say i wanted to go stock on the rom but rooted? With CWM, superuser, maybe an oc kernel.
Or just stick with Prime!
Thanks.
I'm not sure there are any clear advantages to nvflash- it's easier to load the stock firmware with nvflash, but you can also load custom roms/recoveries too, but they have to be converted for nvflash. nvflash isn't available to all TFs because of the SBK issue. We only know the SBK for the low serial numbers, which allows us to use nvflash.
Any of the first four methods can be used to flash a rooted stock rom with oc kernel and cwm. I don't know anything about asus-backup.
Help,
I installed a wrong oc kernal and my tablet is messed up now it keeps rebooting and when it reboots a ton of lines of color i can get it into recovery But THATS it.
I backed it up, but restoring it does nothing...
need help
Wiping everything as well does nothing
if you can get into recovery you could try the superwipe app from revolution rom thread. i just used it yesterday after having problems and i could reflash my backup fresh and revolver rom fresh like brand new. it wipes everything but recovery.
Is your TF101 SBKv1 or SBKv2 ?
Take a look at your serial number, if its below B70 then your TF is SBKv1.
If it is, you can use NVFlash to flash a new ROM, Recovery, kernel and whatever (more info here : http://forum.xda-developers.com/showthread.php?t=1123429)
If it's not, well can you access ClockworkMod Recovery (CWM) ? You can flash an other kernel with that.
If you're SBKv2 and with no need to access CWM Recovery, I think (not sure though) your tablet's done.
it is a b80 and i am ABLE TO GET INTO CWM recovery...

Since you can't boot your TF up, revolver part is not gonna do you any good.
Here's his repository
http://www.gnufabio.com/revolver/dls/
You could try what neofreak01 stated above also
If you can get to recovery, just flash the stock (non-oc) kernel. Reset your oc settings and then reflash the oc kernel.
sent from my cyanogen(mod) vision
So, my brand new Transformer came yesterday (From Amazon) and it has an SBK v2 bootloader (sbk detect under mac, serial is BC0KAS), here is what I understood, and ask for questions, after many reading, can you please confirm or correct?
1- SBK v1 can be rooted, put custom roms, return back to stock, unbrick in case something goes wrong with nvflash. [CONFIRMED]
2- SBK v2 can be rooted? (some say B70 can, or is it just B70 with SBK v1?) [CONFIRMED]
3- SBK v2 can have custom roms? (depends on point 2)? [CONFIRMED]
4- SBK v2 cannot have ClockWorkMod? [Wrong, SBKv2 CAN have ClockWorkMod]
5- SBK v2 does NOT support nvflash, so if you softbrick you cannot recover (I am certain of this one, I guess). [CONFIRMED, if you damage ROM & clockworkmod = BRICK]
What can be done then with an SBK v2 device? wait for developers to find the ways to crack it (as sbkv1), or have an nvflash working?
Is there some petition open to tell Asus to unblock the bootloader as they did with the Transformer Prime?
currently (after 1 day), I am already thinking of returning it back.
I know i might be asking a lot of questions, but information is not easily available in 1 thread.
Update:
New question: with SBKv2 is it possible to return back to stock (Stock ROM, unrooted with stock recovery)?
Thanks in advance...
SBK doesn't keep you from rooting from what I understand, the firmware version does (current 8.6.5.21 has been cracked and can be rooted by nachoroot, or if not can be firmware upgraded to 8.6.6.19 and rooted with razorclaw)
SBK2 simply keeps you from using NVFlash to recover, as far as I know, once you are rooted, you can install CWM recovery on any SBK version.
Just alot of SBK2 owners have not rooted or installed CWM if they did root for fear of losing their recovery (if you bungle the recovery, you may be able to flash your recovery through the ROM, if you mess up your ROM, you can flash another ROM through CWM or stock recovery, BUT if your recovery img is corrupted AND your ROM stops working, SBK1 can flash both via NVFlash, SBK2 is effectively bricked)
EDIT: SBK2 USED to keep you from being able to root when NVFlash was the only method available for rooting and installing superuser and busybox, see here
http://forum.xda-developers.com/archive/index.php/t-1347388.html
I was going to say I will try to NVFlash my device and tell you if it is SBK1 or 2, I assumed it would be SBK2 because it is B70, but lo and behold it was SBK1..I would have been lucky a few months ago before the razorclaw app was developed and SBK2 was rooted, but I didn't get my TF until after that..
So, SBK1 here have gone to stock many times, but cannot confirm the procedure for SBK2 tablets, though I assume it is possible. Thought for sure I was going to be able to come back and say my TF was SBK2 and had been to stock, but nope haha
EDIT: considering you can backup your entire setup via CWM, recovery mage and all, and flash it wthin CWM (like restoring the backup) is evidence to me that you can no doubt unroot an SBK2 as long as you have a working recovery image.
From what I understand, the first thing to do on a new device is to have root (with the tools you mentioned), once you have this (stock ROM with root), you can install CWM, and with CWM you can install custom and stock roms.
but how can I bring back the standard Stock recovery? when I have stock unrooted ROM I can't flash Recovery partition from the Android itself, and nvflash doesn't work on SBK2. can CWM be used to flash a stock recovery over itself?
Is there any chance that Asus will unlock the TF101 when it releases the tool to unlock the Transformer Prime (in February, as promissed)? in case they both use same blocking technology?

Yes you can flash stock recovery over cwm from within cwm, you have to have the file..i found it and have it on my hard drive, but can't remember where i got it from..the same procedure as going stock on sbk1 tablets
The proof that you can flash recovery while in recovery mode is that you can install higher versions or different developer's versions of recoveries from cwm. Im sure when running cwm it is being read from ram so flashing the recovery partition will only affect your recovery after you reboot (i.e. Can technically go into cwm, flash recovery partition first and then flash stock rom, but i believe packages are available to flash both at once, and there would be no reason to do it in this order, but im pretty sure it could be done)
Somewhere on here is a guide how to return to stock to prepare for the ics update, it should contain the odd bits and links to fill in my sparse knowledge.
Getting back to stock ROM and recovery
http://theunlockr.com/2011/11/28/how-to-unroot-and-remove-cwm-recovery-on-asus-transformer/
That's the one!
8329 recovery.zip.. Btw it should be noted that the recovery image is not region-branded, that should mean it will work with any region, while you will need to make sure to get the region-specific firmware..
And i did the procedure in reverse from that thread, not to confuse, but i:
Placed both files (recovery and firmware) into my sd card root
Booted into cwm and flashed stock recovery, wipe everything before powering down
Rebooted into recovery again and flashed the firmware with stock recovery.
I think it will work either way, i left my rooted rom in place so i could install cwm if the recovery flash failed, i suppose the alternative is leaving your recovery in place in case the stock rom flash fails..i just like knowing on the first reboot whether my first flash was successful and not flashing blind imo.

That thread is full of bad information and garbage. I would forget it exists.
I was under the impression from reading different Asus statements that the sbk for TF-101 was going to be released with ICS the way it was with TF-201, did Asus not keep their word on this?

That would be news to me. If you could find a source for this statement, I would be interested.
From what I understood reading (this forum and other sites), the story is different between TF101 and TF201: the Prime has the bootloader locked/encrypted, and with it locked you can't even install the CWM recovery, while with sbkv2 you can do everything except nvflash, so i doubt that asus will release anything for the sbkv2 transformers.
anyway, i am not following the subject, but does the new Prime unlocker allow something like nvflash to work?

Anyway, yes 'Wheelie!' Nvflash for Sbkv2 devices has been released, and works very well on my b70 Sbkv2
it only works on the tf101 though, not the G or Slider.
I'm about to buy used Eee Pad Transformer TF101, with dock/keyboard. It has serial number starting with B90KAS and latest firmware update (ICS).
What is the current status of bootloader unlocking craft? Would I be able to install Ubuntu/OpenSUSE and/or use custom kernels with latest KatKiss ROMs?
I've heard that there are different versions of the TF and one in particular can't be rooted or something. I plan on rooting this weekend but I want to make sure I have a rootable version. How can I check?
With all the methods out there, It's hard to believe you'll have an unrootable tablet.
This only use to be true before RazorClaw, NachoRoot and ViperMod was avaiable.
Back then you'll have to figure out if you have an SBK v1 or SBK v2 to use NVFlash.

Many thanks for the information!
My TF has an SBK v2 because the serial number starts with BB0. My TF was upgraded to stock ICS downloaded from the Asus website (US build version US_epad-9.xx....). My questions:
1) Could you recommend a rooting approach about my situation? How can I check whether the TF is rooted or not?
2) If I flash the full version of ICS using Plan B of ICS - CWM flashable here (http://forum.xda-developers.com/showthread.php?t=1514658), my TF will be rooted, correct?
3) To be able to flash using Plan B, is the following the appropriate CWM I need to install first (note: my TF is not rooted yet)?

Sorry for these basic questions. I've never done any tablet flashing before. Really appreciate any guide and pointers.

You have to be rooted first. Being rooted allows you to install CWM. CWM enables you to flash ROMs.
(NvFlash lets you flash roms without rooting and without CWM, but it doesn't work with sbk2 so you can forget about it.)
1) You root with this http://forum.xda-developers.com/showthread.php?t=1516639 Make sure you read the post completely. The option you need to use for TF101 ICS is OPTION 1.
2) Supposedly the root kit also flashes CWM to your TF at the same time but people are reporting it doesn't work. In that case, use http://forum.xda-developers.com/showthread.php?t=1346180 confirmed to work on TF101 ICS rooted with vipermod.
3) Now you have rooted ICS with CWM. Read up on CWM and how to flash ROMs if you want to.

Hi, I unlocked my TF300T sotck ICS 4.0.3 with the Asus app, I flashed CWM and the root_signed thingy without a problem. I then did a data wipe, cache and dalvik wipe and flashed CM10 stable build for TF300T and the Gapps zip. I reboot and it's stuck on ASUS screen. I'm currently doing a restore of the "nandroid". Will this restore my tablet to ICS? What did I do wrong? How do I get either Cm10 to work or return to the ICS? Also, if I need to flash something else, how do I do it? Does the CWM recognize msd cards? Because all I have on the internal memory is the CM10 which currently did not work for me. I'm a little desperate right now. Thanks.
EDIT: DAMN IT, I just got an error restoring data. What the hell do I do? Please!
i tried restoring again and reflashing cm10 and the gapps and still nothing changes. I did wipe again the caches and still nothing. Also I can't download other roms to the tablet because my computer doesn't recognize the tablet because it hasn't booted and the cwm won't recognize micro sd cards. So I think flashing something else isn't an option. Did I break my tablet completely? I'm almost in tears
I tried several things due to some searches on different forums but nohitng works. I tried wiping caches and reflashing Cm10, didn't work. I tried pluggin my tablet to my computer and sending the asus stock rom via ADB and flashing that, but CWM gives me an "installacion aborted" error. I just don't know what to do nor I understand what went wrong. I did everything according to multiple tutorials. Unlocking, flashing CWM and rooting went just fine. But installing CM10 ended up pretty much destroying my tablet. I wanna kill myself.
I think you have a brick??!! :'( cm10 is jellybean and you where on ics and you probably didn't flash the jellybean bootloader did you?
Sent from my ASUS Transformer Pad TF300T
Not a single tutorial said that I had to do that. Every tutorial says "unlock bootloader, flash cwm, flash root_signed, flash cmrom". I did just that. Are you telling me that my tablet is lost forever?
in most cm threads (except cm9) their is stated that you atleast need android 4.1.1 with it's bootloader or 4.2 with it's bootloader, what i suggest you try is to flash a bootloader and upgrade staight to 4.1.1 you can download the firmware from asus the links are on this guide: http://forum.xda-developers.com/showthread.php?p=39272826 FOLLOW THIS GUIDE CORRECTLLY OR YOU MIGHT PERMANENTLY BRICK YOUR TABLET!!!!
EDIT: if you get an error during flash it's probably the drivers or a fastboot flash brick wich is only fixable by replacing the motherboard!!
Sent from my ASUS Transformer Pad TF300T
If what you say is true, then you can't flash CM10 on a stock ICS tablet, and that goes against every freaking tutorial I've read before messing with my tablet.
What exactly is your bootloader version?
Sent from my ASUS Transformer Pad TF300T
I'm not sure what my answer is. The "bootloader" was unlocked by the Asus app from their website. I did that by downloading (I believe it was V7) the apk from their website and installing that and unlocking the tablet. From there on, I just followed did fastboot flashing CWM and rooting. I never read a tutorial that said "you should flash JB bootloader before installing cm10". In fact I thought that just by unlocking the tablet, rooting and flashing the custom recovery one could just install a custom rom regardless of wether it's JB or not. It's funny because I didn't want to upgrade to stock JB because it seemed buggy from a lot of reviewers, and CM10 was the classic option to have JB and a lot of great features and speed. So I google time and time again how to flash CM10 on a ICS stock ASUS. I just followed the tutorials for that.
is my tablet unrecoverably bricked? I also tried fastbooting and "flash system blob" with the blob for the ICS 4.0.3 firmware, after a while of "sending" the file in the command prompt, I got a blue progress bar in the fastboot screen on the tablet and then "FAILED". So I guess that doesn't work either.
Nothing will work?
Try entering fastboot reboot: does your tablet reboot or does it hang?
cm10 is android 4.1 it seems logical that it only runs on a 4.1 bootloader and not on an ics one! most posts must have said that you atleast need jelllybean 4.1.1
I was confused in the beginning aswell because my phone accepts any rom no matter what bootloader version!
Sent from my ASUS Transformer Pad TF300T
If it makes so much sense that CM10 with JB 4.1 only boots with the JB bootloader, then how the hell one can go from ICS to CM10?! Google tutorial flash cm10 on asus tf300t stock ics and you'll find a thousand tutorials not one of which says you need JB bootloader. I mean, I assume one could upgrade to the official JB rom and then unlock bootloader, etc, but I'm telling you, every tutorial that said "stock ics to cm10" did no mention the bootloader version issue. I'm not trying toblame anyone other than myself for "bricking" my tablet, but I read so many tutorials to ensure I wouldn't mess it up that I'm very upset about this.
I can use fastboot and adb commands. But I haven't been able to flash the ICS stock rom so far. First of all, it's not on the Asus website anymore, and the one I got from the web gave me this error on CWM "instaling update.. installation aborted". I also tried flashing the .blob via fastboot and it also failed. It seems nothing works. Any thoughts, anyone?

Maybe worth a try ? Never been on ICS myself - just thought I'd mention this source...sorry for wasting your time if this is what you already tried.
Yeah, I tried flashing the ICS 9.4.3.30 (my stock rom) and it didn't fly (said installation aborted) and also tried to flash it as a blob and it failed. I guess I deserve this, but I just can't bellieve this isn't fixable.

We would like to know what bootloader you now have. You use the bootloader menu to get to cwm. Tell us how many ICONS you have and what they are. This way we will have more info to consider options if any.
It's ICS. I have the Wipe Data and the Coldboot option. If I'm connecte with the usb cable, there's also the usb icon.
Currently I don't have the tablet, because I send it to a tech support place and they should give me a repair budget (if they deem it repairable, I guess) by tomorrow, but I'm not confident that they'll be able to fix it. So I'm still open to suggestions. Thanks!

I reread the thread and I believe I would make a blob with just stock recovery (4.03) to match your bootloader. I know fastboot is failing on a complete blob but may process something as small as recovery. The blob could also be pushed to your tablet with adb and flash with that.
I made these choices as a place to begin since we need to match your bootloader.
Once stock recovery was in place we could use adb to push a once unzipped stock firmware (4.03) and get stock recovery to install it for us.
Thanks a lot man. When I get the tablet back and you make me that blob I'll definitely give it a try. Although I have a question, I already have the once unzipped stock ICS on my tablet (pushed it with ADB), how do I install it with stock recovery should flashing that blob work?

With stock recovery in place go into bootloader and pretend you are going into cwm that activates stock recovery now. If android lays down we'll rename the zip to EP201_768_SDUPDATE.zip and try again.
I'll download 4.03 and make the recovery blob tomorrow so we'll be ready.
Sorry about that. I read "I would make" as "I will make", lol. Is there a stock recovery 4.0.3 blob on the internet for download? I'll get some sleep now, but I'll try to prepare everythng for when I get the tablet back, assuming I don't have fixed for me by tech support (although I'd love not to have to pay forit, right)

No, there is the full blob in the factory firmware and that is what I'll use. It only takes a couple of minutes to extract the recovery image file which might flash and then re-blob just the recovery partition.
Downloading takes longer than everything else.
Update:
This zip contains stock 4.03 recovery as a blob and as an image file.
Unzip and try flashing the blob - if it fails try flashing twice more or until success. If it still fails try flashing the image file - three times if it fails.
Note:
These are to be flashed with fastboot or adb, not cwm.
Great, thanks man. Unfortunately, I won't have my tablet until at least wednesday because of the holiday on my country (independence day and such). But I'll give it a try and get back to you.
