Issues with Recovery

I have a Transformer B70 and I used the Pure root 8.4.4.11 method
Shown here (http://forum.xda-developers.com/showthread.php?t=1185104)
and I can't seem to get into recovery after following all the steps.
it seems to hang at "Booting recovery kernel image"

I'm having the same issue too.
And what is really weird is that it was working the very first time I did it, but after trying to root the 3.2 update, I can't get it to work anymore. Nor can I get the tablet to see the 3.2 OTA... I wonder if I borked it up somehow with NVFlash. Anyone got any ideas?

Did you read the note about recovery in first post?

my guess is no.

Yeah, I completely missed that. I need to sleep more instead of hacking tablets...
I still don't understand why it worked the first time I did it manually, but after restoring to stock via NVFlash, I can't get the exact same recovery.img file to boot on the same tablet.
Is there a way to wipe the whole flash and start fresh? I had this kind of issue on the GTablet and the full wipe clean and re-install to stock fixed it. Maybe I can look at the commands to do it in the GTab and adapt it for myself.

I just installed clockworkmod recovery though a nvflash method with a rooted 8.4.4.5

[Q] Having SBK2 device, what can and can't be done?

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.

Bump.
This post suggest new Transformers can be nvflashed too.

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?

What can I do with brick? Only waiting for some solution?
Did Asus could repair it for a fee?

RMA
Thinking about calling ASUS to ***** about this tablet being locked and demanding the opportunity to either downgrade to sbk1 or upgrade to a prime. I'll let y'all know my findings.

Until a solution is found, you can use a bricked device as a very nice door stop.

android root .mobi has a released a a solution, i am going to try it, will post results when done

The revival of the thread from the dead! -dun dun dun-!
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?

[Q] Cant install new kernels

Hi guys, I'm using the CM9 ICS with my transformer and I was trying to install a different kernels without any success at all. I've booted into CWM (V5) and installed from sd card but when I restart the machine, It's always with the same kernel. Can someone suggest how to make it work?

How long does the install take? That should give some insight onto what it is doing

Just to be sure, CWM v5 will not read external uSD card, only the internal storage /sdcard. May I know the kernel you are installing?

It takes about a minute to install.
I've tried a few:
TesteyMeh ICS 0.7
Blades
Others...
All of them seem to install fine but when rebooting I see the same kernel version and I cant OC.

have u tried wiping the cache and dalvik before flashing them?

A minute is way too long. Kernels only take like 3 seconds cuz they are small.
Try mount /system under mounts and storage before flashing the kernel.

Flashing a new kernel takes a few seconds. After reboot please pay attention to the blue indicator below the Android figure. It this not appears something went wrong with the first stage of the flashing process, invalid image/zip file etc.
Please use the customized CWM version, just not the flashed one from the Rom manager. I'v good experiences with the R2 (internal sdcard only) as well with the R1 (external micro-sdcard only). I preferred the R1 version.
Btw I'v have the best experiences with my TF101G with the CM9 build of March 29 combined with the quevor-test8 (just NOT from the guevor thread but ONLY from the thread of Richard because it's compiled for CM9) kernel, no reboots and no deep sleeps anymore while 3G and Wifi is working fine. Please do not wipe or clear something before flashing the new kernel to prevent Wifi problems. And I'v the best experiences not using the reboot system now from CWM but using power down and switch on the TF manually.

antond57:
i too have been having trouble getting kernels to allow overclocking...i flash one, all looks ok but when i get to tablettop the kernel info appears unchanged and setcpu wont clock past 1000.
could you maybe please post links to the rom and kernel you used? im having trouble locating the Richards R1 and R2 versions. i would like to see if i can repeat your success w/ these versions.
much appreciated.

I have same issue except worse yesterday. I'm on latest CM9. I tried to flash guevro test 9 and I did wipe both cache. Using roach 2 recovery. Just stayed on Asus screen. Blue bar did pop up and take a second or so but nothing. Checked md5 and all was good.
I had to totally flash ROM again after a full wipe because even a restore from recovery wouldn't go past very first Asus screen. I'm not sure what happened but I'm definitely now worried about trying a new kernel again

Yap, I have the same problem. Nandroid restore did not restore to the previous state. For me, re-flash the ROM fixed the problem (no full-wipe).

Try Using clockwork recovery
I have just flashed guevor kernel as well with no problems. I'm using clockwork mod recovery. Have you tried it?

[Q] CWM recovery bootloop

I'm pissed that I installed CWM recovery... I wanted a factory reset, so I did it. Now everytime I turn on my TF101, I get directed to ClockworkMod Recovery v5.5.0.4. My computer doesn't recognize my transformer now, and IDK how to let CWM use my microsd. I don't know what to do... My serial number is b80, and it's ICS. Latest firmware. I rooted this device with ViperMod Prime, since it can also root TF101. Please help me? I want to get rid of CWM and unroot, so I can sell this.

TF300T BootLoop

Sorry for my english...
Today i unlock the tf300t bootloader and i root it... I flash the Custom Rom JB Hydro 4.1 (i did the ota jb) ... After i want try the cm10... i flash it but it doesn't work... The tab don't work.. i see the bootlogo ... The cmw work, so i tried to restore to jb hydro... but it doesn't work... Now how can i resolve?

hi !
In the recovery mod, try to wipe dalvik, cache and data after that flash your rom again...
if you can try CWM or TWRP recovery ...

I'm having the same Problem
Today i went to CyanogenMOD site and downloaded the most resent Nightly build of Cm10, flashed it into my TF300T and now im stuck in Boot Loop. I used CWM to make a full rom backup before than, but when i do restore from backup everythign goes well, until i reboot it, then it hangs in boot loop again. What can i do? (I followed more than 3 tutorials step by step so i dont know what went wrong. It was OTA JB 4.1.1 , then i unlocked bootloader and rooted, then i did stock rom backup with cwm and then i flashed cm10 nightly and issues started. =(

There is no way of flashing Cyanogen JBs if you are on stock JB. Only Rom available for you is Hydro JB. All otheres are not flashable until the Cyanao Crew get the new Kernel and bootloader to run.

Did you do a full-wipe (wipe data, cache, dalvik-cache, and system) if you did, try TWRP recovery 2.2.2.0 it might say it wiped, but it might be leaving some data behind or you can try a double wipe. I usually wipe front to back, but some people wipe back to front.

The only reason i tried CM10 was to overclock using ezoverclock (if thats possible) because it failed to OC on Stock JB due kernel changes.
Can I overclock using ezoverclock on Hydro JB?
Why didn't my Stock rom backup work either?

Ok then, im going to download stock JB from Asus site , and after it boot ur and start running smooth im goign to restore backup, and hope it all return normal, thanks for the help, i let ya'all know if it worked.
Edit: I downloaded stock firmware from Asus site and extracted the blob file, moved blob file to c:\Fastboot, then put tablet in fastboot mode via recovery, and flashed blob following this instructions to make it work again.
"U could reflash your unit with stock ROM using fastboot. I just unbricked my unit doing that after 5 days of fighting.
This is what I did, I downloaded job update from Asus then moved the blob to c/fast boot, loaded unit to fast boot then typed
fastboot -i 0x0B05 flash system blob
But make sure our boot loader is 10.4 or it will signature mismatch, so down load the appropriate boot loader .
That's what I did at least and my unit is working again. "
So i'm happy again, thanks for support xda-developers !!! (the instructions in the quote are also from xda-developers)
