[Q] Can't boot into Recovery, how to restore original one? - Eee Pad Transformer Q&A, Help & Troubleshooting

I'm trying to access recovery by power + vol down, it starts booting but gives me an error (the android with a "!" signal) and I just can't access it anymore.
My device is not rooted yet, I'm with stock HC 3.2 US 8.6.5.9, is there a way to restore only the original recovery?

There is no original recovery

I'm also having the same problem on my B40 model. Also, can never go into APX mode as I need to root my TF101.

Mine is hard to put into APX, sometimes I have to try a few times, but I got it because it display the usb icon beside the windows taskbar clock and it says "APX device", but it won't work.

I thought the original Recovery restored the internal flash back to factory settings. Before flashing CWM Recovery I remember using it a few times. Am I thinking about the wrong thing?

Place the update.zip on your external sd card.
Wasnt working, got it tho. Installed CWM, flashed it. (After it took me awhile to figure out the CWM Recovery buttons :-/ ) Thanks for the help anyway.

You installed CWM before you flashed it?
Used fastboot to flash the CWM recovery.img then flashed the ICS leak update.zip from the sdcard, I couldn't get it to flash the update.zip without CWM for some reason

So that means the process for unlocking the bootloader for ICS works on HC. Great find (although you almost ended up with a paperweight ).
i did the same as the OP and I've tried the reset button and it doesn't seem to want to work.
Any help would be appreciated.

I can get into APX mode but no fastboot. And as you know you need the CPU ID to get through EUUs, I'm not sure how to get the CPU ID number.
Hello, I have a similar problem, I can enter in APX mode, I have CPUID and I have SBK key but I can not do anything because give me a error like...:can not write to usb....

Can I ask how you got the SBK? That's not available for the A100. The method used for the A500 doesn't work on the A100 bootloader either. If the device is stuck in APX mode then it's bricked and will need to be sent to Acer for repair or a motherboard replacement will need done by yourself or someone you take it to.

Semi-Bricked my TF101

Just picked up a TF101 and it had the Cryo (whatever it is called) OS with ClockworkMod Recovery v5.8.3.4. The OS didn't pick up wifi on the apps but it is on and logged into the router so I did a reset. Once I reset the TF101, i am stuck at CWM. It won't boot into any OS or anything else. I tried almost everything I found googling (this site and others) but nothing works. I did, however, got the TF drivers for my laptop so I can connect to it but I can't get the USB debug option on (of course).
So what are my options? how do I "unbrick" this thing? is this what some people call it soft-brick as it does boot but there just isn't any OS in there? I tried to put the OS zip file from Asus on a MicroSD but when I went to install zip from sdcard, it i can't get to the microSD to install it. it doesn't find it at all.
what can I do? what are the steps in unbricking this thing? I got this for my dad for father's day (chinese father's day which is TODAY...) and would like to get it to him.
Thanks in advance!
Is it in a CWM boot loop? Meaning when you reboot the tablet it keep going back to CWM?
Try this to see if you can boot OS.
Turn off tablet
Push and hold Vol down plus Power button
Wait till you see a screen that give you two options
Wipe data or Cold boot Linux
Choose Cold boot to boot into OS.

still stuck in CWM. I held it down and no options came up except to push vol +. tried both and regardless of what i do, it just goes right back into the CWM menu. it seems there's no OS to this tablet anymore?
Is there something I can do via USB cable to flash a ROM in there?

If you have ADB working, you can push a ROM file to internal memory and flash it.
Alternatively you can NVFlash a compatible ROM.

Sorry to sound ignorant but what's ad and what command (extra code after the .exe) do I add afterwards?
I'd try to flash a ROM via NVFLASH.
You may download it from here, but you must know if your TF101 is WW version, US version or any other. You must also know if your device is SBK1 or SBK2. That depends on the serial number. For example, mine starts by B50 and it's SBK1. If yours is SBK2 then you'll have to take a look at wheelie. If not, take a look here.

However, I'm not responsible for any damage your device might suffer.
Take a look at that and tell me
here's the endall- easyflash version 0.8.3b whitekidneys just updated it and saved my brick. it'll save yours too. just install it on your computer, along with naked drivers 0.7, put the tf in apx, and flash. literally that easy.
Follow the link to easy flash / nvflash and follow the steps...

need help with nvflash

ive used easyflash and the flash completes 100% but doesnot boot up just stays on the nv screen or it shows battery empty sign?
anyone? i have problems getting it into apx mode, been trying for half an hour and still cant get it in to apx. would the bootloaders be a reason why i cant restore via nvflash?
Could it have gone flat during a flash? and it wont go into apx mode after the failed flash? Someone can correct me if im wrong but im sure partitions doesn't effect nvflash. what screens are you stuck at currently?

There is option right... as far as i remember, when yo flash stock using nvflash it removes root access... so you need to root and flash cwm again using nvflash right... so best option is removing root n going back to stock using easy flash.... boot it normally... let it settle and then root it again and install rogue recovery
That what I did when I had issues with my tablet...

ok got it. easyflasher 0.8.3b fixed it. whitekidneys has it working great now. the problem was getting easyflasher to finish the recovery kernel. something stopped or failed to transfer to the tablet while flashing the recovery. that means no recovery. that means i get stuck in apx mode. he updated it to 0.8.3b and it worked right away.

Hey there,
I had exactly the same problem , I had a boot loop tried easyflasher and after that only apx worked.
Now I have tried the new version and it boots again but the bootloop remains...

You flashed a recovery and reflashed the os? When you say new version you mean 0.8.3b right? Cause 0.8.3 doesnt work. You have the newest system update zip from the asus site in the asusupdate folder? When you say bootloop do you mean you can only get to your recovery or do you mean a real bootloop- it just keeps rebooting on the eee pad or asus screen?

I used the option Flash stock/unbrick at first but this didn't help so i tried flashing a recovery and then reflash the os from my external sd card but this result in an error code 7.
Yes I used 0.8.3b ( at least the zip I downloaded says so, program itself says 0.8.3)
With bootloop I mean that I can access recovery/apx but if the system trys to boot it gets stuck at the "Asus Inpiring inovation..." screen.
And yes I copied the latest zip from the asus site to the update folder.
I also tired putting the DE_epaduser9_2_1_21UpdateLauncher.zip from the asus site because I'm from germany and thought it may help...
But none of that worked for me

Helpppp, I brick my TF700 and JB

after JB update i install TWRP then i remember that i shouldn't use it until a new update. I wanted to do a factory reset but having a custom recovery would not let me do it. I was looking for a guide to restore stock bootloader, it didn't work completly cause i still had TWRP has recovery. After that i notice that i did get 4 icons, RCK-android -usb - data wipe. after factory reset wasn't still working, i press data wipe to see if that works and now i don't get anything more than TWRP recovery (which doesn't work with JB) but when i reboot my tablet holding volume down i don't get any message at all. Goes straight to recovery.
I somehow managed to do the EXACT same thing!! All I get now is TWRP, no matter what button combination I press at startup. I can't seem to get it to recognise my external SDCard either.
Anyone have any ideas? Our tablets are dead in the water!!! :crying:

once you in recovery (see 4 icons), use volume down to switch to USB icon, then use volume up hit it twice, now your device is in fastboot mode. Connect your usb cable (make sure usb debugging and unknow source are checked in settings). From your pc now you can flash using script or manuall push it.

i dont think so i cant toggle down or up in cwm, is there some other way to flash it?
There used to be a flash binary that worked with adb (I.e. via recovery). I've not seen or heard of it for a while, but the fact that recovery can still be flashed from booted Android tells me it's still available. ROM Manager and GooManager both allow you to install recovery, so I would start with decompiling those...
First you need to access you tablet (while it's booted in CWM) via adb shell.
Second, you need to verify that the recovery can access the internal eMMC - "ls /dev/block/mmcblk0*" should list at least 8 partitions.
Then, you can put a flashable zip into and the installation command onto the cache partition - the procedure is exactly the same as the method to manually install incremental dlpkgfile updates.
