[Asus  Eee Pad Transformer Prime] Restorer:
Thanks mate - sounds a breeze the way you put it :D.. Pretty sure I know the answers but 2 more questions just to get it straight in my head:

1. If I decide to go straight from finishing off NVFlash to installing HB 2.31, then will I just go for your "Upgrade Hairybean 2.31 (4.2.1) Bootloader & TWRP (2.5).zip"? It won't be put off by the patched Android.mobi bootloader and custom CWM?

2. If I want a rest and go for the downgrade route first, your " Downgrade Hairybean 4.1.1 Bootloader & Recovery.zip" is all I will need, right? In other words I can ignore the part about flashing another 4.1.1 ROM?
[Asus  Eee Pad Transformer Prime] flumpster:
Yea, both correct.
[Asus  Eee Pad Transformer Prime] Restorer:
Many thanks. Still just a bit worried that the 10.4.2.15 version of the bootloader will be there at the end with the 10.4.2.18 ROM. However, I'm guessing since they are both 4.1.1 there is no real danger. I'm not even sure how or even if bootloaders change over minor Asus upgrades - all I know is 90% of all those bricked primes I've been reading about over the last two years have resulted from mismatched bootloader/ROM with CWM also somewhere there in the mix of culprits :D:laugh:
[Asus  Eee Pad Transformer Prime] flumpster:
A mismatched bootloader and rom wont cause a brick. It might not boot but it wont harm it.

A mismatched bootloader and recovery can cause a brick.

The downgrade zip in hairybean thread installs the 10.4.2.18 bootloader and at the same time installs the correct TWRP to go with that bootloader so there is nothing you can break unless you decide to go and flash your own recovery afterwards.

The same goes for the 2.31 bootloader and TWRP upgrade. That flashes the 4.2.2 bootloader and the correct TWRP for it.
[Asus  Eee Pad Transformer Prime] Restorer:
Ah OK, so even though Flatline bootloader and my ROM are different versions, the custom version of CWM they are using ensures no problem? What about all this "CWM is just not compatible with JB bootloader so you must use TWRP" that we have been hearing over these last several months? Is it just that the Android.mobi team has made it so it is compatible and the CWM devs have for some reason been reluctant to do so?
[Asus  Eee Pad Transformer Prime] flumpster:
Yes, It is not hard to make a compatible version of CWM for the different bootloaders but there was never official releases after ICS.
[Asus  Eee Pad Transformer Prime] Restorer:
OK, thanks a lot for all that. I think I got it all straight in my head now :good:.

for the moment brickable

I have received zero replies or suggestions to my post http://xdaforums.com/showpost.php?p=45998409&postcount=47 so have continued in the blind. Now I know that I have to use wheelie/nvflash adequate to the bootloader (ICS/JB) and the "-r" option is already present in the newest builds of wheelie, so there is no "v0.2"

I still remained bricked (only APX) and I get:

E:\>wheelie.exe -r --blob blob.bin
Wheelie 0.1 - Preflight for nvflash.

and it hangs there. Both under Win32 and Linux.

Info for the developers: trying to restore stock I accidentally flashed the bootloader partition with my bootloader dump (--read) rather then a bootloader from unblobbed stock firmware.

Again any hints would be welcome.

I have taken this tutorial straight from NvFlash

1. If I decide to go straight from finishing off NVFlash to installing HB 2.31, then will I just go for your "Upgrade Hairybean 2.31 (4.2.1) Bootloader & TWRP (2.5).zip"? It won't be put off by the patched Android.mobi bootloader and custom CWM?

Copied ROM and TWPR loader into internal memory and flashed Upgrade Hairybean 2.31 (4.2.1) Bootloader first. Then went into Recovery to flash ROM but it looks like I can not find rom file anylonger ! Device even doesn't recognise external SD card mounted into dock. How do I flash rom now ? Please help.
[Asus  Eee Pad Transformer Prime] flumpster:
The device wont recognize an SDcard in the dock when in recovery and your internal got wiped during the bootloader upgrade which it says in the hairybean instructions and that is why your rom is missing.

The simplest way to do this is just to put the rom onto a micro sdcard and put it straight into the tablet (not the dock) and flash it.

The harder way to do it (if you don't know what your doing) is to adb push the rom to internal sdcard.
[Asus  Eee Pad Transformer Prime] dzikusk:
I have tried to insert SD card with rom file into dock but TWRP doesn't allow me to select it (red dot) only Internal Memory can be browsed.

Perhaps I'll try with different SD card (I tried 8 GB SDHC). Can you tell me adb push command if SD card will not work ?
[Asus  Eee Pad Transformer Prime] flumpster:
I just said above you cannot put a card into keyboard dock.. It has to go into the prime itself.

If you are already doing this and just saying dock but not meaning keyboard dock then let me know.
[Asus  Eee Pad Transformer Prime] dzikusk:
By dock I mean keyboard slot for SD. My TF201 doesn't have SD slot. Or is there a way to open it's case and insert it somehow ?
[Asus  Eee Pad Transformer Prime] flumpster:
Your TF201 has a micro sd slot on the middle left hand side. Underneath the volume buttons and the micro hdmi port.

edit.. I made a mistake and said right originally.
[Asus  Eee Pad Transformer Prime] dzikusk:
Found it :) but tablet still doesn't recognize it.

There is a message "E:Unable to mount '/external_sdcard'

and E:Unable to mount '/sd-ext'
[Asus  Eee Pad Transformer Prime] flumpster:
Make sure the card is formatted to fat32 and put the rom on it.

Then put the card into the prime before you boot into TWRP.
[Asus  Eee Pad Transformer Prime] dzikusk:
Tried with 2 different micro SD cards with no luck. Formatted both to FAT32. Still device doesn't recognizes cards. Any advise ?
[Asus  Eee Pad Transformer Prime] flumpster:
Go into TWRP and make sure you have adb drivers installed and try.

adb push romname.zip /sdcard/
[Asus  Eee Pad Transformer Prime] dzikusk:
I've formatted my SD card again, this time did not use quick format mode and put rom onto it again. Started recovery and supprising device successuflly detected my card. I'm installing rom at this moment. It is taking 1 hour already. Is that normal ?
[Asus  Eee Pad Transformer Prime] flumpster:
No, that is not normal.

Aroma can get "stuck" now and again tho and if you hit the bottom left of the screen where the back button would have been it would free it.
[Asus  Eee Pad Transformer Prime] dzikusk:
I pressed power button and suppriselly ut showed that installation process has finished correctly. Now i'm loading OS :)
[Asus  Eee Pad Transformer Prime] manning33:
Hey guys,

Real quick. My tf201 is hard bricked. Never had blob files backup because I was on JB when I finally decided to root my prime. Am I still screwed or will these forum get er back online?

no fastboot. stuck at asus logo. device unlocked.

Thanks people
[Asus  Eee Pad Transformer Prime] McJesus15:
If it's already bricked then no. This utility backs up device specific images/blobs from a working device to restore at a later point
[Asus  Eee Pad Transformer Prime] manning33:
Dang. back to shedding some tears. IF I would have waited 1 more month..... I could have snagged my blob files.

You think there will ever be a way to unbrick these things with no blob files or should I just sell it for parts and move on?
[Asus  Eee Pad Transformer Prime] manning33:
You know I had twrp on it. Went to install clockwork from rom manager. Never booted again.
[Asus  Eee Pad Transformer Prime] HORiZUN:
You could sell it for parts, or buy a motherboard and swap it out.

I was in the same boat. Sold the bricked prime on ebay, bought a refurbished unit from Newegg.
[Asus  Eee Pad Transformer Prime] kornball:
Finally had the free time (and cajones) to work through this. About an hour later, I have my blob, bricksafe, factory-config, and unlock-token! Thanks for the awesome work! Now to flash some ROMs without fear... Thanks so much for the hard work! :highfive:
[Asus  Eee Pad Transformer Prime] Restorer:
Many thanks to the AndroidRoot team for this. The method worked for me just fine in the end :good:.

I did have a couple of problems worth watching out for:

1. I thought at first the blob generating hadn't worked since it took only a few seconds and not the fair amount of time suggested in the guide.

2. Also the upload failed.and adb could not get access to the AndroidRoot folder. But the folder was right there in /data/media and I was able to copy the files over manually.

3. I just couldn't get the device to boot into apx mode - turned out I was just trying too hard with the key presses. Worth concentrating on more precision button pressing :D.

4. Windows 8 is a real pain trying to re-install drivers properly. I was pretty sure I already had the proper ones installed already but it wasn't until I put it into test mode that the drivers deleted properly so I could reinstall correctly.

5. Couldn't figure out how to get out of nvflash when the line nvflash --resume --go did nothing - in the end I pulled the plug on it and held down the power button - no harm done thankfully :D.

Looking forward to flashing Hairy Bean tomorrow - I'd forgotten how exciting all this stuff can be :laugh:.

request advice about this NV FLASH

Hello I have a TF201 running black baked bean rom 4.2 on a unofficial JB Bootloader can I use this program to to nvflash? I have tried to nv flash before but couldn't because I was told I had changed my bootloader to JB, so is it possible to do this now and how do I make this Blob file , im not sure about this and dont want to brick my tablet , thank you all in advance

NVflash JB vs TWRP

Im on TWRP atm.

Is it recommended to go to NVflash JB? Or will both things do the same?

Flashed this the other night. I hard bricked a prime about a year ago (post jellybean update) and its nice to have the safety net on the replacement I bought.
[Asus  Eee Pad Transformer Prime] riven67:
Just finished uploading my backup files to a bunch of cloud accounts, I also have it on 2 hard drives and will keep a set on a usb thumb drive. I know overkill but I have read to many stories about people with nvflash (the original one) that could not find their back up files when they needed them! This way I am covered, LOL, but anyway thanks for all the hard work it went smooth and I had not a single problem. It is nice to feel safe flashing on this device for the first time since I unlocked it! Going to try out all those roms I was to scared to try before. :good:
[Asus  Eee Pad Transformer Prime] ThiaiZ:
I can confirm it works on Windows 8 64 bits. Needed some extra but it works. Send me a PM if you are having trouble, I can maybe help you.
[Asus  Eee Pad Transformer Prime] thenrz:
I picked a super time to pick my Prime up again for some flashing fun... :D

Will report back with sure success.

EDIT: Didn't run into a single issue except for the --resume --go not working. Been waiting on this for a long, long time.

Seeing the bootloader spring forth from apx was poetic indeed!

EDIT2: Lost the ability to access the micro-sd. I think was mentioned previously and it's late so...

Flashed the 2.5.0.0 twrp blob through fastboot. Rebooted and let it get to Android after the blue bar finishes in the bootloader screen. From there, no issue accessing the micro-sd slot.

Feels awesome to be brick proof. Can't wait to see what's up with Linux :)
[Asus  Eee Pad Transformer Prime] Tenzo_O:

Thank you so much!!

I was on the 10.4.2.18 Bootloader version and I followed all the steps and it worked like a charm!

Thank you so much!!

Was there ever a solution for the "Error 3 receiving response from command" issue? I'm having that too and I've come up with zero answers.

---------- Post added at 09:32 PM ---------- Previous post was at 08:34 PM ----------

I'm having the same "Error 3 receiving response from command" issue as jynlude. I'd love to follow your advice. What are the right versions, and where might I find them?

---------- Post added at 10:26 PM ---------- Previous post was at 09:32 PM ----------

Okay, I've done everything I can think of. Uninstalled and reinstalled drivers. Rebooted everything that can be rebooted. Disconnected from the internet, turned off firewall and anti-virus. Tried it a second time and got an entirely new error, but they always run in sequence. First try, I get Error 3. Second try, I get -

[=] Chip UID: 0xfffffd20

[-] Unknown error or incorrect RCM protocol version. nverror: 0x1.

I'm using the files provided in this guide - https://www.androidroot.mobi/pages/g...ash-jellybean/ - as well as the instructions. Everything works fine until the wheelie command, and then I got nothing. Google has no real results other than here and one other page where it's just me and the same guy who posted here that have the problem. I *really* hope someone posts with a solution or potential solution. Just recreated the blob files, still no go, same error. I'm kinda at wits end here. I already hard bricked this thing once and lucked out on getting a new motherboard put in it for $40 total. I'd love to play around with custom ROMs, but I want some recovery ability in case I screw something up. I really REALLY want to get this working, where do I go or who do I talk to for help? There's nothing on the page with the official guide, and the OP said not to message him in any way shape or form. So.. now what? Does anyone here have enough knowledge to help me get this to work?

[Asus  Eee Pad Transformer Prime] haimn:
I know it wipes the apps and system settings, I just asked if it delete the internal memory too. but it's not relevant anymore because I flashed TWRP so thanks.
[Asus  Eee Pad Transformer Prime] Arfyness:
Whooops. I started from the wrong place!!

Awww crap. I flashed the Flatline AND BOOTLOADER described as "Transformer Prime TF201: 10.4.2.15 (INCOMPATIBLE WITH HAIRY BEAN)" but I was not aware it is also incompatible with the stock rom 10.4.2.18 which was my starting point.

My TF201 will boot normally, and the bootloader shows 10.4.2.15, but like prana22, my mounts won't work in flatline. So I never got my blobs.

I don't want to "try" anything else without asking for what to do next !!!

Chronology of my mistakes:

- OTA to 10.4.2.18 (a year ago?)

- Unlock bootloader (today)

- flash Flatline (I'm using naked drivers and the minimal adb/fastboot)

- full boot to android, power off

- boot recovery, do wheelie step 1

- full boot to android, power off

- boot recovery, do wheelie step 2

- write this post before messing up something worse

When step two happened RIGHT AWAY I suspected something was up. The androidroot guide says go make some tea while this does it's thing, cause it's gonna take a while.

I'm sure it's not disastrous (yet) because the OS will boot, and I can access ADB and Fastboot like usual. But I really would like to get my blobs in case I make a more grave mistake in the future. (I plan on trying out a few new roms, since I finally got the balls to unlock the bootloader)

One more thing ... I still get this message at the top of the screen: "The Device is UnLocked"

I am pretty sure it's supposed to change at some point? Maybe only ICS?

Given all the above, I have these questions, and don't want to guess what order they should go:

How do I get back to the original stock bootloader?

How do I get a working recovery?

How do I downgrade to 10.4.2.15 in order to make nvflash blobs?

THANK YOU COMMUNITY - I have faith in you. :o)
[Asus  Eee Pad Transformer Prime] Restorer:
First of all, from your desciption, you have not done anything wrong!

You did this correctly. The bootloader 10.4.2.15 is completely compatible with the stock ROM and is indeed the one you should be using.

This is just a mistake in the guide. It takes only a few seconds. This also had me panicking :).

I think you may well will find you do have your blobs already. Take a look in /data/media on your tablet before you do anything else. Like you, I did this coming straight from a locked 10.4.2.18 and quite a few unexpected things happened, which I just put down at first to user error. Not only does the upload not work but for me I couldn't access the Androidroot folder on the tabletand had to find and copy over the files manually. If you search for my username in this thread you will see my experience and initial reaction was similar to yours. In particular look at THIS POST.

Incidentally, the "Device is Unlocked" message will remain for the rest of its days.
[Asus  Eee Pad Transformer Prime] Arfyness:
Wheeewwww

Wheeewwww!!! Thank you for confirming this. I had found this thread which gave me the idea that the bootloaders were not incompatible. I didn't find it again though till just now.

This is exactly what happened to me. When adb couldn't find it, I naturally assumed it is not there. But also I am not rooted (the .18 OTA killed root) so I also don't see anything in /data from inside android.

I did notice at the time some messages about mounting in Flatline. Namely, I noticed the first "attempting to mount /data" has a "Done" after it. There were subsequent other "attempting to unmount" or "attempting to mount" lines and NONE of them had "Done" after them. I guess it doesn't need to be a fully working recovery. It's clear that it's purpose driven to enable nvflash.

I can't help asking ... what is the precision way to press the buttons, as opposed to trying too hard?

Huh, ok. It must have been something else I saw (on wwjoshdew's youtube channel) where that text is replaced (or drawn over top of). Whatever it was, he was pretty excited about it. Thought it was this tho.

Restorer, thank you. :o)
[Asus  Eee Pad Transformer Prime] Restorer:
Haha. That part was most defintely user error! By this time the combination of pressing too hard through the sides of a folio case combined with hours of panic, sweat and failure just started to take their toll :laugh:. In the end I took the damned thing out of the case and clicked and held the buttons as gently as I could and it finally worked :D.

Anyway, glad you got there in the end :good:. It's hard to even think about criticising the Androidroot team when their great work has been such a life-saver but there are a couple of steps in their guide which are just a bit misleading ;).
[Asus  Eee Pad Transformer Prime] Arfyness:
Hey, there it is

:laugh: Hahahaha! I didn't picture that at all!! "Panic, Sweat, and Failure!" I'm stealing that. :laugh:

You were right, I did find my AndroidRoot folder. Mine landed in the root of my internal storage. Which ... oh. Which is mounted at /data/media, ha! so that part makes sense. It seems like some people don't have those inconsistencies, from reading through these forums. Odd, that.

I've got the thing to the point I have pulled out all data which I wish to save from oblivion, so looks like time to continue the nvflash process to gather the rest of those files from wheelie.

Then I'll try to figure out which TWRP file to flash. I imagine it would be the JB file .img format. But I'm not sure enough just yet. They don't have anything to say about the flatline-installed bootloader, though. They only mention A) "AndroidRoot.mobi custom EBT (ICS only)" though there are .img files for ICS and JB -- and B) the stock bootloaders ICS and JB which have .blob files ... that's on this page. It looks like any given one is flashed with the exact same fastboot command, just .img or .blob depends what BL I have. :confused: I sure don't feel like putting the wrong one on.

I don't imagine you flashed twrp after you got a nice fuzzy feeling from having all those nvflash backup files safely tucked away?

Or anyone?

Thanks again :D

EDIT: Got APX, Naked Driver installed, Got files from nvflash commands. Copied files zealously to Drive, Box, Dropbox, Mega. =o)
[Asus  Eee Pad Transformer Prime] Restorer:
I have replied to your post in the Q&A section on how to install TWRP. Yes, I would say your first "next step" should be to get JB TRWP flashed.

Now you have your backups, you should be good to go choosing a custom ROM. Needless to say I would personally recommend you start with HairyBean 2.31 before getting too adventurous. The thread is long but the instructions in the first few posts are still 100% relevant and easy to follow and you will still get plenty of support there.
[Asus  Eee Pad Transformer Prime] Arfyness:
Yes, I saw that. Thanks so much! I know which one to get now.

Yes! reading about HairyBean is the entire reason I unlocked. :cool: I also want to try CM10 and eventually CM11 after they have a release candidate. So having an easy way to restore *everything*on*there* is important.

Any thought for further reading on APX / nvFlash? I've been going through forums for different nVidia devices here, and I'm getting fascinated on how it works.

Stay Awesome,

[Asus  Eee Pad Transformer Prime] Restorer:
Not sure if there is actually that much info around on this. Beyond knowing it is a mode which, thanks to androidroot's modified bootloader, provides us with access to the Tegra's own low-level command set, I've never looked any further into it - not that I'd understand any of it if I did :laugh:.

ISTR there is a bit of technical stuff on the inner workings of NVflash on the anroidroot.mobi website - you could make that your first port of call but I doubt you will find any details of how they set about cracking the actual encryption ;).
