[WORK IN PROGRESS] Current state of root / flashing / nvflash (updated May 6th) - Eee Pad Transformer General

As of today 6th May 2011 the Eee Pad is pretty much cracked. We can flash boot and recovery and have a working root and unsecure boot and koush's Clockworkmod recovery.
The one thing we can't do is use nvflash to try custom bootloaders etc. This is because APX has been locked with a SBK and we have currently no method to get around that. Thus nvflash will fail with the error
Code:
rcm version 0X4
Command send failed (usb write failed)
It is interesting to note that the ASUS German blog claims that the bootloader and root privileges are both openly accessible, which (at the moment) is not true.
Here a few key combinations for anyone interested:
VOL_DOWN + POWER (continue holding VOL_DOWN when it starts booting until you get a prompt) = Bootloader which offers two prompted options: (1) Recovery if you press VOL_UP within 5 seconds or (2) Data wipe if you press VOL_UP later. None of these seem to offer any USB devices like fastboot etc.
VOL_UP + POWER or VOL_DOWN + VOL_UP + PLUG IN USB = NVFlash mode. It clearly is the NVFlash APX device that we see appearing, but it barfs as soon as we run any sort of nvflash on it (Many Windows and Linux versions have been tried). Please note that in this mode the screen stays completely blank and the only way to get out of it is the following option:
Hold POWER for ~10s = Forced power off. This always helps if you are stuck in some weird mode and nothing on the screen

I'll repost this in here then, as it adds a bit more info to the post above:
-Volume down button + power button for 5 secs = Life surges into the pad
Eee Pad logo + Asus logo ... keep holding buttons for 1 more sec = New screen with:
Android_WWeeepad-user bootloader < e> released by ww_epad-8.2.2.6.1-20110325".
Checking for android ota recovery
Checking for RCK... Press key <VOLUME_UP> in 5 secs to enter RCK
-Pressing up = next screen below
Booting recovery Kernal Image
Image in middle of screen and some sort of loading bar
(then goes straight to)
Exclamation mark (!) + android logo on screen
-Not touching any other buttons = screen then goes to:
Press <VOL_UP> to execute or <VOL_DOWN> to cancel wiping data (with a pulsing "Wipe data" icon in middle of screen)
-Pressing volume up = well... I didnt do that for obvious reasons.
-Pressing volume down = boots linux... and back into honeycomb normally.
-Volume up + power button dont seem to do anything.
-Power button for 5 secs = normal boot up.
-An 8-9 second hold down of the power button seems to switch it off from any screen.

I was expecting to see an HD link to some video's from spankwire

Maybe a stupid question but we do not need the dock to get an adb shell isnt it?

Great find
Need to learn about Android now, I'll chuck this in the reference thread (When i make one )
Thanks

We cannot activate fastboot on this device until we have the right nvflash tool... Once we have nvflash there shouldn't be any further obstacles.

What NVFlash commands have you tried... can you even run these?
nvflash --bl fastboot.bin --go -w
nvflash --bl fastboot.stock.bin --go -w
You would need those files in your directory... Its like booting image with fastboot without writing....

As I said, nvflash doesn't work. Not a single command.

So it doesn't seem that open after all. Nvflash has not changed this much. Have you only ran those commands in Nvflash mode.
Is the device recognised when you boot in recovery.

yes, it's either locked, or as simple as a new revision of nvflash is required.

Recovery and normal boot both offer ADB. We get the right device in NVFlash mode, it's just the software we have cannot talk to it after the first few bytes...

Will pay to fix my A500

Not sure what happened exactly, but while flashing the newest update for a particular persons JB ROM (he will remain unnamed) everything went fubar. Bad. Wasn't recognizing my sd drive, couldn't flash a back-up, tried one of the solutions here on XDA.....now I am without recovery. The tab will boot up, but it gets to a password screen. I have no clue what the password is.
Though I can't pay a fortune, I am willing to pay someone to fix the tab. It's all based on trust since I will send you the tablet and trust that you will return it. Of course, I will pay for return shipping also. I love my tab, but it's useless to me currently.
Please PM me if you want to take on this task. Thanks.
replied to your 'other' post but i guess it should go here
from this thread here
a hard reset wipe userdata and cache
a manual hard reset will do the same thing if you do not have the unlocked bootloader
fastboot erase if you do have the unlocked bootloader
also a stock acer update.zip but I guess you've tried that, maybe a stock ics update.zip would work
I'd be happy to take a look at your tab for free, but being on the other side of the world doesnt make that feasible unfortunately!!
however I'm sure someone else closer to you will be more than willing to help
good luck with it m8

edit:
and this from here
For anyone still having this problem, I don't see a fix on this page and I managed to figure it out for myself despite being a total noob to this stuff. To be clear, this is what happened to me: I wanted to roll back to 3.0.1 and needed to start by doing a factory reset. To do that, I followed some instructions in the A500 forum that said to do the following:
1. Power Down
2. Make sure the Screen orientation is off (slide to left while landscape mode)
3. Hold down the right volume key (Volume up (+)).
4. Hold down the Power Button.
5. When it buzzes let go of the power but keep hold of the volume up button (+)
rock the screen orientation switch quickly back and forth once.
6. Should say :
Erasing Userdata....
Erasing Cache...
After doing those steps, after I got the Erasing Userdata message I then got an error about an invalid boot file. Then when it powered back up it asked me for a password and it wasn't taking the password I previously had on the device. I was freaked out that I bricked my tablet in my very first attempt at moving to a custom ROM so I frantically searched the Internet to no avail. But then I stumbled into a help topic on the Acer UK website when doing a Google search. When I watched the video in the help topic (click here to see it) I found that this may have happened because the steps are slightly different in the video than what I was given. I used the steps below instead and successfully performed the factory reset (differences bolded):
1. Power Down
2. Make sure the Screen orientation is ON (slide to right in landscape mode so orange is showing)
3. Hold down the right volume key (Volume up (+)).
4. Hold down the Power Button.
5. When it buzzes let go of the power but keep hold of the volume up button (+)
rock the screen orientation switch quickly to the off position and leave it off (don't toggle it like the instructions above say to do).
6. Should say :
Erasing Userdata....
Erasing Cache...
This worked for me anyway; I got the Erasing Userdata then Erasing Cache instead of the error message and then a password request. I just wanted to document the solution in case anyone ever needs it again.
No luck. Doing any of these things always brings me to Skrilax's bootmenu mode, but selecting Boot Recovery just brings up Android with an exclamation point in it.

Have faith grasshopper!!!! Its just like running adb commands
Boot to fastboot mode
connect yr cable to PC
open cmd prompt from fastboot.exe folder (which is included in the sdk with adb.exe)
type in "fastboot devices"
it should return a ? - this means you're all good!
type in:
fastboot erase userdata
fastboot erase cache
fastboot reboot
to flash a recovery - u will need a recovery.img - I just used one out of civs nvFlash package
fastboot erase recovery
fastboot flash recovery recovery.img
fastboot reboot
so now you should be fully wiped and have a recovery installed...if you get the dead android again, we'll head to the next step....and we'll need to know what rom you're actually running!!

You should have it if you have flashed the patched bootloader if not then see attachment:
extract the zip to say, C:\android (good idea to keep all yr flashing stuff in a folder like this)
dont actually open the folder where fastboot.exe is located, you want to press down
"shift" & right click on the folder itself to open cmd prompt -

Can't unlock bootloader on my Nexus 7

After command "fastboot oem unlock", I get the error:

How to solve this problem? Thanks in advance.
What bootloader version?
Try this:
- Power off
- Power on into bootloader/fastboot mode
- on the PC: fastboot reboot-bootloader
- now try again
this usually fixes those kinds of problems for me.

Bootloader version 3.34.
fastboot reboot-bootloader did not help(( displays the same error.
I haven a friend with a new N7 delivered with 4.1.2 on that same bootloader, 3.34. He cannot update to 4.2 OTA. I even tried to sideload it for him with no luck. All I can deduce from this is that that JB version should not exist with that version of bootloader. Something seems borked.

Sorry for my english, I don't ynderstand you.
I did so:
Connected my device to PC.
Booted into fastboot by pressing all keys.
Selected recovery mode. Displayed "android with !".
I holded "volume up" and "power" button for 15 seconds. And then apx mode booted
Don't hold the buttons like forever.
Press them and release them again, also try some other combinations if that one doesn't work.
If you keep torturing the powerbutton, of course the device eventually reboots.
Be creative.
Use common sense.

Thanks... but when I'm using "wipe data/factory reset" - my device freezes, and when I restart him there is no changes, and I also can not unlock my bootloader.
I think that to unlock bootloader needs debugging mode. In recovery mode there is menu item "apply update from ADB". So I can enable adb. How to unlock bootloader or flash by this way?

[Q] Tablet with unknown password, how to reset or wipe data?

I was given an a500 tablet that has a password it on that is unknown. The person that gave it to me said that there was a nag stating that an update was available and to reboot. Before the update there was not a password to his knowledge. After rebooting, the OS loads to a point where a password is required to continue.
The tablet is not rooted and usb debugging is not enabled.
I have tried downloading several full rom packages from this thread
http://forum.xda-developers.com/showthread.php?t=1816560
After downloading the rom package i rename to update.zip and transfer to a sd card and boot up the tablet holding volume up and power. When the tablet boots it displays
Erasing Cache Before SD Update....
SD update cme:recovery
--update_package=sdcard: update.zip
secure boot: image SOS checksum fail!
I then searched some more forums and was able to get my CPUID and SKB from within Ubuntu and those are
CPUID=288424342c0a217
SKB=0xDF1A0000 0x83A50301 0xBB86E703 0x7C302103
I tried using that with an EUU from above link but that does not work either.
Ultimately I would like to have root, custom recovery and custom ROM. But for right now if someone can just help me reset this to factory defaults so i can use the tablet that would be much appreciate.

did you try a factory reset...volume - plus power?
The password can only be removed by wiping your tab.
To do this manually using the buttons:
1) Turn off your tablet,
2) Rotation lock to your left;
3) Press Vol+ (which is closest to the rotation lock) and power on simultaneously
4) As soon as the tablet vibrates you can release the power button and you should start to switch rotation lock left and right till you see
Erasing Userdata...
Erasing Cache...
Vol+ is still pressed;
5) The tablet starts to format
6) Your tablet will be as clean as it can be.
Hi gears177 and dibb_nz, thanks for responding.
gears177 before i had read dibb_nz response i would have said yes i tried a factory reset but after reading it I now know I was not doing it correctly.
That being said, I tried doing a factory reset and still have not had any luck.
This is what I see doing a normal boot of pressing the power button until the unit vibrates. The screen turns on and says 'acer' in the middle for three minutes and 18 seconds. After that it says 'android' with like a scrolling light across it for an additional 40 seconds (is this the bootanimation?) and then pops up the password screen that I cannot get past.
I then turned the unit off and attempted a factory reset. I held down the Vol+ button and the power button until the unit vibrated. I let go of the power button and continued to hold the Vol+ button while toggling the screen lock switch. The unit displayed 'acer' in the center of the screen again and then in the upper right corner said 'erasing user data' followed by 'erasing cache' I continued holding the Vol+ key the entire time. After 3 minutes and 18 seconds the word 'android' came on again and after another 40 seconds i was back at the password screen.
I then tried holding the power button with the Vol+ button until the unit vibrates. I then let go of the pwr button and began to toggle the screen lock switch until 'erasing user data' followed by 'erasing cache' was displayed. I then let go of all buttons to see what would happen and it sat on the screen with 'acer' in the middle and 'erasing user data' followed by 'erasing cache' in the upper right hand corner for well over an hour until I turned the tablet off.
Am i still not doing something correctly? Thanks again for taking the time to help.
Weird....you did everything right, not sure what the problem might be.
Think best bet may be to use the unbrick tools to reset the tab
The simplest one to start with is an update.zip. put on yr ext sd
and flash. There's one in the root guide in my sig along with lots of other
useful info.
The other way is an EUU...this requires your cupid, which you probably
don't have...it can be retrieved but involves a fair bit of detective work!
If you have any other questions about the process then ask away.
Edit: just reread thread. ...what part of the EUU failed??
The other option is to flash the unlocked bootloader, civato has a sticky
in the dev forum
In regards to the EUU method, I have downloaded this file from the Acer Stock Firmwares thread: EUUs_SBK_Acer_A500_1.016.05_COM_GEN1.
I extracted the file and then ran the PBJ20upgrade.exe file. Because I cannot turn on USB debugging I let the program time out and then when the window stating the program cannot detect an Iconia Tab Imanually put the tablet in APX mode with a paperclip pressing the reset button and power button. When the power button on the tablet lights up white i plug in the usb cable click yes to continue and enter my CPUID on the next screen. I click next and see upgrade is underway displayed. The tablet then vibrates, displays 'acer' in the center of the screen and 'entering acer download mode' in the upper right hand corner of the screen. When this happens the program immediatly displays We are Sorry! The upgrade process failed. Please follow the instructions for recovery. I have tried following the steps and clicking retry but the outcome is always the same.
I have not had time to the try the upgrade.zip you mentioned or flashing the unlocked bootloader. When I do I will report back.
The only other thing I could suggest is to run the nvflash unlocked bootloader, see sticky in dev. Try running via ubuntu, this has been known to work when windows throws a tantrum..sometimes it's a matter of perseverance with all the methods until finally it will just 'work'

Have you tried using a paper clip or something small to factory reset the Tablet? I know there is a small hole somewhere which should work. Good Luck!
THANKS
Thanks. This was exactly what i needed. I appreciate it.

the password can only be removed by wiping your tab.
To do this manually using the buttons:
1) turn off your tablet,
2) rotation lock to your left;
3) press vol+ (which is closest to the rotation lock) and power on simultaneously
4) as soon as the tablet vibrates you can release the power button and you should start to switch rotation lock left and right till you see
erasing userdata...
Erasing cache...
Vol+ is still pressed;
5) the tablet starts to format
6) your tablet will be as clean as it can be.

zenpad 3s 10 Z500M recovery bootloop

I was fiddling with my device (not rooted) and I gave the wrong command in fastboot:
Code:
fastboot erase cache
.
I then gave
Code:
fastboot continue
This was surely a **** up but I don't understand why erasing the cache partition seems to have broken the recovery/fastboot mechanism (I understand why it probably broke android though).
My device is now stuck, whenever I turn it on it goes directly in the recovery 'splash screen' showing 'no command'.
My understanding is that from the recovery 'splash screen' I'm supposed to press some keys combination to get to the recovery menu, but none seem to work.
Pressing both volume up and down for like 10 second reboots the device, so I assume it's not an hardware button problem.
Pressing power + volume up with the device powered off does not go to fastboot (but I'm quite sure it did before).
Neither adb devices or fastboot devices detect the device when connect to my linux pc by usb.
Any suggestion?
Any solution?
I have done exactly the same as you, and am now stuck on the 'no command' screen with the dead android icon flashing every 5 or so seconds. Did you manage to find anyway out of this. I have tried numerous button combinations and I cannot get to either fastboot or recovery, so my tablet is basically bricked. Any help would be immensely welcome.

Sadly, no
I never managed to solve this. I tried everything without luck. I even contacted Asus, and they confirmed me that the right button combination for this device is the following: press and keep pressing the power button with volume up for 3 seconds, then let the volume button go and keep pressing the power one. A recovery menu should appear at that point, but never did for me.
I still don't understand how deleting that partition could break the recovery mechanism, but this seems to be the case.
If you (or anyone else for that matter) ever manage to solve this, I would appreciate if you could write about it here: my device is currently gathering dust in its box
Thanks
Thanks for that. I'll let you know, if I have any luck.
Did you try using the SP Flash tool at all? I have tried this, but it claims the scatter file is invalid and I can't find a way around that.

I will have to look into it, since I'm not familiar with this tool. Where did you get the scatter file?
Sadly right now I don't have the tablet with me, and I won't for several days. When I will, I'll give this a try and report back.

You can get this tool here https://spflashtool.com/
As I understand, the scatter file is in the zip of a ton. So, I downloaded this: ASUS ZenPad 3S 10 (Z500M) FOTA WW_V14.0210.1806.33, unzipped it and used the scatter file from that, but it comes up as invalid. This may be because this isn't the right sort of Ron file, I'm not sure. So, at the moment, I'm stuck.
Still trying
I've used information from the following sites, but have still not solved. Let me know if you have any luck.

Stuck in Boot Loop

Have searched the forum but came up empty.
Hoping someone can help.
Purchased the phone used back in December and have been using it as-is. Two OTA updates came through fine. The latest OTA update has it stuck in a boot loop.
- I can get to fastboot with power and volume down buttons but all of the options either turn it off or stick it back in the loop again (Essential logo with powered by Android, NO dot animation)
- Can't see it via "adb devices" since developer mode was likely not enabled
- "fastboot devices" can see the phone but can't change slots or do anything else
I saw two other people who've posted something similar but no solution. Is my phone garbage?
Any help is appreciated.

Damn, that's a bit unlucky, this March update said it would make recovery from a loop after OTA update easier to recover from, which might just have helped you. Sorry not sure how to help fix at present.
you can try flashing one of these https://forum.xda-developers.com/essential-phone/development/stock-7-1-1-nmj20d-t3701681
be sure to pick one with the fastboot images

A couple of questions:
- Is your BL unlocked (or is OEM Unlocking enabled)?
What happens if you try executing "fastboot flashing unlock"? NOTE: this would WIPE your data if successful.
- Can you get to the Recovery mode? It's when you pick "Recovery" option from fastboot mode, see the lying android with an exclamation sign, then hold Power and press VolumeUp to get to the Recovery menu.

Thanks for your response.
- I dont belive OEM unlocking is enabled.
- I can get to the fastboot menu, but the recovery mode option just takes me back to the 'powered by android' logo, not the green dead robot.
- When I try fastboot flashing unlock, I get the below error:
=============
FAILED (remote: Flashing Unlock is not allowed
)
finished. total time: 0.013s

Will this work even though I cannot see the device via adb? AND the device state is "locked".

Dang... :\ Yeah, the last error means you don't have OEM unlock enabled. So, you can't flash the bts image via fastboot. One last thing I could think of is trying to get to recovery by the button combo. Although, if you are correct in saying you don't have USB debug enabled, it won't do much good, i.e. you won't be able to flash an OTA... :\
While device is OFF, press and hold Volume-Up button while pushing Power button to boot.
Your device will now be in Recovery mode. An Android logo with red exclamation mark should appear on screen. Hold the Power button, then press the Volume-Up button one time to see the recovery menu.
can you try this command on bootloader:
fastboot OEM unlock
