Bootloader Options Missing - Help - Transformer TF300T Q&A, Help & Troubleshooting

Hello everybody,
I have a tf300t that I was in the process of unlocking and flashing a new recovery and rom to. Needless to say something went wrong and I had to follow the NVFLASH guide to get the tablet back up and operating. It will start ICS just fine and let me access ADB and I also have access through APX. I do not however have the option when I hold volume down to choose to boot to recovery or fastboot modes. If I hold the volume down button during startup it only says COLD BOOTING LINUX.
During the NVFLASH I installed the blob file for TWRP ICS version 2.5.0.0. I know the recovery is working because if i go into the settings and choose to factory restart the device it will reboot into TWRP and automatically do its thing factory resetting and then the tablet will reboot to a fresh ICS asking me to input my wireless settings and account. Also if I put a stock firmware file from asus on the device it will notice it and tell me there is a update for the device if i want to install. If I say yes it will restart the tablet into TWRP and install the rom automatically. However on reboot the rom fails to start and I have to do the NVFLASH process to get it back to ICS.
Through ADB I used the adb reboot recovery command but it reboots the tablet and never enters TWRP just strait to ICS android, and the same goes for adb reboot bootloader or adb reboot-bootloader. If somebody can help me boot directory to TWRP recovery so I can try to wipe the device and install a custom rom I would greatly appreciate it!!!!!

You have to reboot after the initial nvflash first. Your partitions are laid out different in 4.0, 4.1, and 4.2 so flashing the twrp blob right after your nv restore likely put things in incorrect spots.
Id redo the nvflash, boot it up, set things up properly, THEN reboot to bootloader, reflash recovery using fastboot. That should fix you right up.

These are the commands I used to for NVFLASH posted by tobdaryl. He has you install the twrp recovery image in the 2nd to last command. I also believe I tried flashing the blob.sos as he said this was the stock recovery but that didn't get my bootloader options back either. Is there a command I should be doing different?
wheelie -r --blob blob.bin -created with Nvflash install
nvflash --resume --download 4 blob.EBT -created with blobunpack
nvflash --resume --download 10 blob.APP – created with blobunpack
nvflash --resume --download 6 blob.LNX – created with blobunpack
nvflash --resume --download 5 recovery.img-ICS twrp recovery image name
nvflash --resume --go
then press volume down to enter

Well, he would be the Nvflash expert it seems......
What happens when you only run the first command ? Thats what flashed the bootloader.... Also... you dont type the " -created with blobunpack" part. It should look like this :
nvflash --resume --download 4 blob.EBT
nvflash --resume --download 10 blob.APP
nvflash --resume --download 6 blob.LNX
nvflash --resume --download 5 recovery.img
nvflash --resume --go
then press volume down to enter
The recovery.img would be the twrp / cwm img file

Yes i ran the instructions without the -created by... and they all ran successfully. I tried only writing the first command and it wrote successfully, however there still is no choices when I hold volume down on the tablet and power on, it go's strait to cold boot Linux.
For the heck of it I downloaded a custom ICS rom renamed it to something a stock asus firmware would have and threw it on the tablet. It found the file and asked to update. I let it update which it restarts goes into the TWRP 2.5.0.0 recovery and flashes the file and reboots to the custom ICS rom. So for now the tablet will allow me to install zips if i rename them to a firmware that asus would use.

What I think I'm going to do next is download a 4.2 bootloader & Rom zip file and rename it to a asus stock rom file. Hopefully it reboots to recovery installs it and when it reboots after that have a 4.2 bootloader that works and a 4.2 recovery that allows me to install a custom rom. Fingers crossed!

Cannot install CWM recovery on 8.4.4.11

Hi,
I have been trying to install CMW recovery using the brks guide (http://forum.xda-developers.com/showthread.php?t=1185104). The problem is I did successfully rooted the device and even installed titantium backup after the installation but when trying to boot into CWM recovery I get stuck on "Booting recovery kernel image" and nothing happens. I have tried to swith the recovery.img with recovery_failsafe.img and have tried both versions v4 and v5 beta 2 and had the same results.
Could some one please advise me what am I doing wrong?
Thank You.
Same problem here,
I didn't backup my old recovery so now I can return to my stock one.
Installing the supplied stock recovery gives the same result.
Same problem. Subscribed to thread
I've restored my transformer to stock using this:
http://tabletroms.com/forums/showthread.php?1071-Asus-Transformer-NVFlash-Stock-3.1-Recovery-Roms
And waiting till Asus will publish the 3.2 on their site.
Same problem for me...
Running stock 8.4.4.11
Rooted just fine.
Cannot get CWM to work
Same problem here...
I used v6 and can't get into stock recovery or CWM recovery...
I kindda remember I have 8.4.4.5 bootloader b4 and my CWM recovery works.
I am on 8.4.4.11 bootloader now and the CWM recovery doesn't work.
Can someone here having the same problem verify their bootloader version?
The bootloader version should be on the top of the screen when you are stuck at "Booting recovery kernel image"
Thanks everyone.
If you have a stock rooted US 8.4.4.11 and you rooted from 8.4.4.11, then this recovery will probably work.

You'll have to adjust the batch script to flash it or put it in the right folder, or just get funky with the command line
Code:
nvflash.exe --bct transformer.bct --setbct --configfile flash.cfg --bl bootloader.bin --odmdata 0x300d8011 --sbk 0x1682CCD8 0x8A1A43EA 0xA532EEB6 0xECFE1D98 --sync
nvflash.exe -r --download 5 \path\to\cwm-solarnz-84411.img
Edit: I updated the partition in the nvflash code!! It should be 5!

brk's version is for 8.6.5.6. With these stock roms, I think the kernels have to match the bootloader. The actual CWM recovery is the same, just with the kernel from 8.4.4.11.

Oh, so the recovery have kernel too? Learn something everyday.
So, should I not try the recovery from solarnz's post? http://forum.xda-developers.com/showthread.php?t=1093818
Thanks,
What I posted is the recovery from his post, but with the kernel for 8.4.4.11. He didn't update the version numbers in the file, so 1908 is the same as 1902, or whatever shows in the actual recovery.
You can flash it if you want, but it will be broken again.

That solved my problem.
Nice to have a clean 8.4.4.11 Transformer with root and cwm both working
I rooted & installed cwm without any problem but when I booted into cwm to perform a backup or flash a file, it keeps saying "can't mount /sdcard" and cwm is not working! Any idea what went wrong? Please help, thanks!
Hello, you must have a microSD card plugged in your TF.
I had the same problem as you and I solved it by removing and inserting the card again while in CWM.
Then I successfully mounted /sdcard in CWM menu "mounts and storage"
Hope it helps

Will this work for WW ?
I have WW and seem to have the same problem. Recovery doesn't work.
EDIT: Doesn't work. "adb reboot recovery" just makes the transformer boot normally. =( I guess I'm out of luck....
I don't know if it will work because I don't know what differences there are, if any, between the US and WW kernels.

nvflash on TF300T, is it unbrickable?

Simply put, I flashed system over my boot partition. I can boot in Fastboot and APX. I dont have the option to go into recovery anymore and I used to have three selection in the boot menu, now I have two, wipe data and fastboot (USB icon). Could I recover my unbrickable TF300T?
I have my unbrickable files
I flashed TWRP
I made a backup in that
System was good
I extracted CM10
I typed: "fastboot -i 0x0B05 flash system boot.blob" from the CM10 files
The tablet was stuck on the AndroidRoot screen
I restarted the tab with vol down and power
I entered TWRP
I restored my backup
I played with the tab
I tried installing CM10 again
I connected with the Fastboot protocol
I typed: "fastboot -i 0x0B05 flash boot boot.blob"
On restart, when I press down arrow + power, I immediately goes into Fastboot USB download protocol. I cant even get the system to show me the RCK screen, which would allow me into TWRP. I can only immediately go into fastboot mode, restart in APX mode, or restart the tab and stare at the AndroidRoot 9.4.3.30r01 with the ASUS logo in the middle.
So what is this, a soft brick? and more importantly, how can I restore my system with nvflash? Is this the way: http://forum.xda-developers.com/showthread.php?t=1757077 ???
And yes, I am very new to this. I took my time pouring over every instruction and document except on how to get CM10 running, I guess you cant just "wing" it.
I will be running this command tomorrow:
nvflash --bct create.bct --setbct --bl blob.bin --configfile factory-config.img --create --verifypart -1 –go
Is this the proper syntax for restoration using the unbrickable nvflash files? I want to restore my partitions, will this do it? Please, if you have tried this command, let me know how it turned out for you, Thank you.

may have bricked

i decided to try out some ROMS (my first time trying any of this stuff)
yesterday my tablet was locked, stock and rooted, 4.0.3
1. i unlocked the bootloader successfully
2. today i did the NVflash and got through it alright
went through the whole process backedup all the files i was supposed to
3. then i put TWRP on it, that went alright too
4. i messed up putting this ROM on it: Asu-Ics_R-2 TF300 HYDROPONIC
5. tried an NVflash restore http://forum.xda-developers.com/showthread.php?p=40432730#post40432730
wheelie -r --blob blob.bin -created with Nvflash install
nvflash --resume --download 4 blob.EBT -created with blobunpack
nvflash --resume --download 10 blob.APP – created with blobunpack
nvflash --resume --download 6 blob.LNX – created with blobunpack
nvflash --resume --download 5 recovery.img-ICS twrp recovery image name
nvflash --resume --go
got all of that except the last step:ICS twrp recovery image
i didnt make a TWRP recovery image
now the screen is always black until i run the wheelie command (step 1 above)
so luckily my windows computer does recognize the tablet with the apx driver installed
i can not get into TWRP, cause the screen is black
i didnt even think it was turning on until i connected via USB and Wndows made the connection sound

Fresh restart with NVFlash help

My TF300T can be brought back to life by:
APX mode
Wheelie
Nvf restore of original files
Nvf blob restore
Reboot
Goes to fastboot
Follow fastboot wipe sequence
Try to push blob (will fail for size error)
Restart
Back to APX
Wheelie
Nvflash files again with stock recovery (won't work with custom)
Boots into android like a fresh tablet
Any attempt to get to recovery gives dead android.
At the same point, any attempt to fastboot flash a recovery fails.
Any ideas how to get recovery back so I can get back to customizing?
Anyone willing to use NVF to pull a stock ICS partition table and rawread all their partitions just to see if I can manhandle it all back into place with NVF?
TIA,
Dean

For new recovery, did you try
Code:
fastboot -i 0x0b05 erase recovery [enter]
fastboot -i 0x0b05 flash recovery /path/to/recovery.img [enter]
fastboot -i 0x0b05 reboot [enter]
I tried that to flash a recovery in fastboot. I got no error, but any attempt to enter recovery will either lock the tablet in the case of TWRP (tried many versions. focused on 2.5.5.0), or the dead android in the case of stock recovery. I'm beginning to think there's something wrong with my recovery partition. I'm also concerned with the size error failure if I try to flash a system blob from fastboot.

bootloader error 0x00000000

Well, what happened is :
that i was trying to root my Transformer tf300t
and i got as far as unlocking the bootloader
so i was having trouble flashing the twrp recovery image
and i think i accidentally erased the stock recovery image
so now my tablet it's not (full bricked) still boots up but doesn't have a recovery image
and now when i boot it into bootloader mode and try to go into RCK it just gives me this
error bootloader unrecoverable 0x0000000 (in red)
how can i flash the stock ROM again if this error ?
anybody ?HELLP

Please try this:
Go to Asus and dl the latest Stock. Unzipp it 2 times. You should have a blob file now in the extracted folder. Put this blob in your fastboot folder.
Open cmd and type:
fastboot -i 0x0B05 flash staging blob
Let it run. It seems that nothing is happening for about 5 Minutes. The whole thing can take up to 20 Minutes, so just stay calm and wait till it’s finished.
Now you should be back to full Stock with Stock recovery. Good luck!
THanks !

Thank you ... it worked i think
but i used a little different command line i used :
fastboot -i 0x0B05 flash system c:\adb\recovery.blob
now i'm still having problems trying to flash custom recovery i want to root the Tablet
what the problem seems to be for me is that i boot the the tablet (tf330t transformer 4.2.1 JB )
to fastboot mode then i get the 3 choices (RCK, Android,Wipe Data)
but when i try to flash the TWRP recovery img with Fastboot it always gives me an error saying (error cannot load img file)
is there anyway to fix this ? and does this root the tablet?
Dear daveSAPIEN can you give us more information about the file used during the flash , actually am facing the same problem as you but nothing seems to work
thank you
