That could have been it, the thing is that in order to get back to ICS i had to use CWM and TWRP wouldnt work lol, now to get on JB used the reverse lol
[Asus  Eee Pad Transformer Prime] jcoleridge:
Worked wonderfully on the latest TWRP and androidroot's bootloader. Very good job, thank you again!

Just to confirm I'm on a Prime sold in the UK, I had hairy bean 1.2 based on TF300 Firmware. I followed instructions 100% and it worked great for me. No problems.

Thank you :)

Recover disapear

Hi,

I just flashed JB coming from a ICS rom using CWM and goes well.

I just realized that I don't have a recovery anymore. Help !!
[Asus  Eee Pad Transformer Prime] JoeyDelp:
Worked perfectly, thanks a million! :)
[Asus  Eee Pad Transformer Prime] casperl:
I did without problems...
[Asus  Eee Pad Transformer Prime] Striatum_bdr:
Read again first post all is here. You must use nvflash to install modified twrp.
[Asus  Eee Pad Transformer Prime] whycali:
Yes, I have done it 5 times to troubleshoot another issue. (of course after the first time the bootloader remains the same)

BENCHMARKS

Craig's [ROM] TF201 JB JRO03C 10.4.2.15 (US) Stock Deodexed default data location

VS.

Craig's [ROM] TF201 JB JRO03C 10.4.2.15 (US) Stock Deodexed with Data2MicroSD Modification

using a SanDisk 64GB Ultra microSD card

Each setup had same apps installed/disabled. For testing purpose I enabled performance mode, turned off WiFi, Bluetooth and sync. I entered Airplane mode. I used no live wallpapers or widgets. Each install had Enable init.d, EXT4 Mount Tweaks and SysCtl And DNS Tweaks modifications applied.

TESTS PERFORMED

Androbench, AnTuTu, SQL RL Benchmark, Vellamo

RESULTS AND SUBJECTIVE ANALYSIS

Please see the attached images for detailed data and results comparisons. I used Photoshop to paste screen caps together for ease of viewing, but used the actual results to do so. Clicking on an image will open it in a larger format for viewing.

The results show a definite speed gain in using the Data2MicroSD mod in data operation specific benchmarks like Androbench and SQL RL, less so of an overall usage advantage in benchmarks such as AnTuTu and Vellamo.

My subjective analysis is that the tablet seems somewhat faster to the same overall. Certain apps like StumbleUpon seemed markedly faster. Dolphin Beta seems faster, though Dolphin HD seems the same. Not sure why. The internal memory, which is supposed to now be seen as a Removable storage is not being seen by the ROM or Windows right now because it is still in ext4 format (Craig will address this in a further update.) I have has zero issues with ANR's but did have a few pauses on app openings when I first installed the MOD which seem to have gone away now as it has settled in.

IN CONCLUSION

I plan on keeping the mod for a while as it does seem to add a bit of speed. YMMV

Hope this helps some of you decide.

One thing one can definitely take away from the benchmark scores is that stuff can vary from minute to minute so real world feel is always more important.

[Asus  Eee Pad Transformer Prime] Tempie007:
overall the benches show a good increase of I/O performance but watch outl I/O bench results vary a lot from time to time.

make sure to turn off running apps and wifi while running it for least amount of hickpus and calculate average of multiple runs.

from user experience perspective: without data2sd i experienced loads of anr message, playstore was slow, huge delays in google reader.

with data2sd ; all gone! (sandisk mobile ultra)

new daily driver!
[Asus  Eee Pad Transformer Prime] Fireplug:
Yup, agree. That is why I did all of that above. :)

Guess what perfomance we could have with the new faster sd cards.. omg asus why you gave us so bad internal storage :(

Tapatalked!
[Asus  Eee Pad Transformer Prime] craigacgomez:
@Fireplug & @Tempie007, theoretically, disabling journaling on the ext4 partitions on you microSD will gain you some more speed... I am working on the modified boot image to fix the issues with the @Fireplug reported (with the Asus storage daemon)... but I have been super busy this week and it's been hard finding time to sit back and get this done...

And @Fireplug, thanks for the comprehensive test results!!

[Asus  Eee Pad Transformer Prime] owenbeals:
It looks like after flshing this Rom I lost Fastboot.

I decided to flash recovery via GooManager then I proceeded to Reboot Recovery.

It just hangs on the ASUS splash screen with "unlocked bootloader" message in upper left corner.

I can not access fastboot at all

Am I PermaBricked or is there a way out of this?!
[Asus  Eee Pad Transformer Prime] biggem001:
first off, l2read. op says flash only his twrp and thats it.

try getting into nvflash, power + vol up, use wheeling and then nvflash the .img given in OP. pray.
[Asus  Eee Pad Transformer Prime] craigacgomez:
If your have nvFlash enabled... you will be able to recover... otherwise, chances are slim unless you can somehow get into fastboot mod... it's not the ROM that resulted in the fastboot issue, it the incompatible recovery you flashed... I have mentioned this in BIG BOLD RED letters in the OP...
[Asus  Eee Pad Transformer Prime] owenbeals:
No nvflash so looks like I'm screwed

I read op all the way to where it said "want custom recovery"

If I had only read a little bit further.

Smh

Edit:

Looks like this will be a $100 mistake. Broken TPrimes go for about $150 on Ebay, then It looks like I can grab a used working one for about $250.. not the worst outcome. Let this be a lesson for the rest of you. Read the ENTIRE OP not just the first 3 quarters of it!
[Asus  Eee Pad Transformer Prime] biggem001:
try the options in the brick-fix thread in the dev forum. try all key combos... i feel as if nvflash should work as i've seen people who've done your error and nvflashed out of it
[Asus  Eee Pad Transformer Prime] Striatum_bdr:
Man, he said he doesn't have fastboot access and didn't install nvflash so he can't unbrick. ...
[Asus  Eee Pad Transformer Prime] frusso:
I am in the same situation. Before flash this rom i was on cm10 nightly with TWRP 2.2.2.0 and the AndroidRoot bootloader. After flashed i have seen the bootloader is came back to stock (see "This Device is UnLocked" on lboot).

Really I don't know if I have nvflash installed. I think yes, I have all nvflash files saved and also I have extracted the blob.bin files (and other files and saved it in three copies !!)

I have flashed latest TWRP via GooManager and now when i start the device hang in ASUS splash screen.

I have also problem (on ubuntu) with wheelie, I think that the device starts in APX mode but can't be sure because wheelie doesn't works on my ubuntu.

Each time i try to start wheelie, i receive the error message:

./wheelie: 1: ./wheelie: Syntax error: word unexpected (expecting ")")

Suggestion ? (Sorry for my bad english)
[Asus  Eee Pad Transformer Prime] biggem001:
what actual wheelie command are you using. to flash the twrp, use:

wheelie --blob blob.bin

nvflash -r --download 5 twrp-2.2.2-jb.img
[Asus  Eee Pad Transformer Prime] YoMarK:
Reason enough for everyone to just stop flashing ROM's, and make your Prime NVFlash ready FIRST.

It's pretty simple, and in the future it will save your ass, there is no excuse to not do it.
[Asus  Eee Pad Transformer Prime] Hawke84:
is it not possible to use someone elses NV flash files? im guessing that there might be issues with serial number etc?
[Asus  Eee Pad Transformer Prime] craigacgomez:
Yes, the files generated when enabling nvFlash are very device specific... no chance it will work across the board...
[Asus  Eee Pad Transformer Prime] GreginNH:
Process

Morning ,

Just so I understand the steps and process. I am currently running the Virtuous ROM off the .28 build.

Please tell me if the steps I think I need to take are correct. I want to gain NVFlash, a correct recovery and this ROM.

So, first run through the steps to obtain nvflash by Androidroot.mobi. So once that is done I am now on that custom bootloader.

So if I then want to install this ROM, do I need to do the steps to install the custom TWRP recovery listed in the OP, first, then install install this ROM, or install the ROM and then do the steps to install the custom TWRP, via nvflash or the other 2 methods listed?

I am comfortable doing any and all of these steps, just want to make sure I am doing them in the correct order :)

Thanks!

Greg
[Asus  Eee Pad Transformer Prime] craigacgomez:
Note to everyone using this ROM... eyeballer has updated the official TWRP recovery and it now has a JB compatible version... I recommend moving to this version... it can even backup boot partitions...

Go the the TWRP recovery thread and download the version of the recovery compatible with the new Jelly Bean bootloader. IMPORTANT: Make sure you get the Jelly Bean version or you may brick your device... As of writing this, the version of TWRP compatible with the JB bootloader is openrecovery-twrp-2.2.2.1-tf201-JB.blob

First nvFlash, the ICS version of TWRP or CWM... then flash the ROM, then flash the JB version of TWRP...
[Asus  Eee Pad Transformer Prime] GreginNH:
ok, that makes sense. Thank you!!
[Asus  Eee Pad Transformer Prime] Fireplug:
You are very welcome, @Craig! Thanks for giving me a reason to make them.

Just a small update.

While using MTP to transfer large amounts of files from my Windows 7 64bit laptop I found that the Prime became pretty unresponsive to doing anything else at the same time.

However, not sure if it is partially because I just added the modified JB build.prop from Demandarin's thread to go along with my previous setup from my benchmark post but, I just started a Google play update of a bunch of files and while that was going on I was streaming using Dolphin to stream music using a Flash plugin and there was absolutely no lag or slowdowns. That was previously unthinkable on my Prime before I stated all this with this ROM. :)
[Asus  Eee Pad Transformer Prime] Theshawty:
Is the JB recovery blob from eyeballer's thread broken? it cannot be loaded when trying to flash it w/ fastboot.

Fastboot -i 0x0b05 flash recovery openrecovery-twrp-2.2.2.1-tf201-JB.blob

error: cannot load 'openrecovery-twrp-2.2.2.1-tf201-JB.blob'
[Asus  Eee Pad Transformer Prime] Hawke84:
dont blob files have to be flashed from the staging partition? i thought fastboot recovery flash had to be an unpacked (unblobed) img image file?
[Asus  Eee Pad Transformer Prime] joeyddr:
yeah i flashed mine with the dd command from a terminal window and it worked fine.
[Asus  Eee Pad Transformer Prime] craigacgomez:
No it works well... make sure the blob is in the directory you are running the command from...

It is a blob file and can be flashed via fastboot... in fact, you cannot flash anything unblobed via staging...
[Asus  Eee Pad Transformer Prime] Theshawty:
I am, yet it still fails to open said blob file, and I have tried re-downloading like 10 times...
[Asus  Eee Pad Transformer Prime] Hawke84:
Would odexed version be faster to boot or does it not make much difference?
[Asus  Eee Pad Transformer Prime] wwjoshdew:
I just updated (and made a video) to Jelly Bean 100% Stock. Thinking about doing that downgrade because I have ran NVFLash (made a video on that too) and it would just be fun to do it, and get it on video. If you were to install the OFFICIAL update from the asus website, could you flash the supersu or superuser zip and have root when it boots into Jelly Bean?

More detail: If you're on an ICS rom with TWRP recovery, you can flash the official update from Asus, and be 100% stock. But for the BRIEF moment when you still have custom recovery and a custom bootloader, could you flash the supersu or superuser zip BEFORE rebooting to Jelly Bean, which overwrites custom recovery and bootloader.

Also... Say you were to super wipe and install that official update from asus in twrp recovery... Where would the root backup stuff from OTA RootKeeper be? A full wipe and installing the official rom would erase the backup, right?
[Asus  Eee Pad Transformer Prime] flewpastu:
ok so im not complaining or *****ing at anyone as i have updated to this ROM and it is installed and very smooth running but i didn't have a lot of time and or misread the OP but regardless i installed the ROM and rebooted to flash the updated SU and TWRP ... uhhh not happening i lost root and again my own fault so now its too late untill a work around is available ... now before ianyone says it ill let ya know now i did not NVFlash so let this be a lesson to those nvflash it or read carefully ... the good news is its running and very smooth at that just dont have root and not sure how to get it back at this point but again i dont have time lately but i do want to say thanks for all the hardwork that goes into this and all the awesome Roms
[Asus  Eee Pad Transformer Prime] GreginNH:
D/L

Anyone try downloading this ROM ...It never starts...maybe there are 8000 of us trying at the same time!~~ lol

And THANK YOU craig for putting this together as well as all the folks who spent time setting up and explaining the nvflash procedure...this is awesome!!

** Got the file, just a little slow today ! ***
[Asus  Eee Pad Transformer Prime] craigacgomez:
If you upgraded to JB using the Asus full stock ROM, you would need to flash TWRP for JB via fastboot and then you can flash Superuser via TWRP...

If you use a full wipe script (which I do not recommend since it messes up things), you would lose any ability to recover root using Vodoo or any OTA root keeper...

You could flash TWRP for JB using fastboot and then flash Superuser...
[Asus  Eee Pad Transformer Prime] flewpastu:
i tried but all i see are a few icons one that says RKC i think then androiid, a usb icon and a wipe data icon when i try the RKC it starts an update then errors out android icon cold boots i havent tried the usb and didnt trust the wipe data any help with this would be great only asking no pressure at all as i know you guys are all very busy people
[Asus  Eee Pad Transformer Prime] promiseofcake:
Thank you. Anyone else still getting notifications for the ICS update? I froze the updater apk to prevent them.
[Asus  Eee Pad Transformer Prime] Fireplug:
Hmm,

Seem to have found a glitch that might be related to the data2microsd mod... at least it never did this before I did the mod.

In Dolphin Browser, if I go to a site with a large jpg picture that extends down larger than the screen when I try to swipe up to reveal the bottom of the picture it often just shows white background instead of the part that was initially hidden. I have deleted, reinstalled, restored any number of different ways and it is still doing it. Also in Dolphin Beta when i did a Google image search the thumbnail results will show up for a brief second then they disappear and just leave white background.

I may try to start all over again from scratch and re flash everything to see if I can fix it and then will report back here.
[Asus  Eee Pad Transformer Prime] whycali:
It is doing that because you dont have a recovery to load from the rkc button. You are in the right place. go back there, push vol down until the usb icon is highlighted then pus vol up to select. this puts you in fastboot mode. connect to your pc, put the file where fastboot is and enter the command to push it A reboot should install
[Asus  Eee Pad Transformer Prime] frusso:
Ok, now i am in nvflash. Running the first command my tf201 goes in nvflah but now what i do ?

First of all i don't know where to get the file twrp-2.2.2-jb.img and also i think the this command will flash a recovery and not my bootloader. It's right ?

I have seen that on twrp site there is a new recovery ( http://teamw.in/project/twrp2/93 ) but the istruction referred to .blob file to flash via fastboot, but i am on nvsflash not fastboot. What i do ?

many thanks in advance
[Asus  Eee Pad Transformer Prime] Fireplug:
The usb logo one is the choice that puts you into fastboot mode.

please read up on how to use fastboot mode before doing anything though
[Asus  Eee Pad Transformer Prime] craigacgomez:
Do not flash the blob via nvFlash.... in fact, you don't need nvFlash to flash the recovery... boot into fastboot and flash the blob from the twrp website
[Asus  Eee Pad Transformer Prime] frusso:
The device don't boot in fastboot, the only thing that works is the nvflash.

I was confusing by the file extension, i thought that the .blob file was a nvflash image of partitions.

So i have done many test flashing image tf201-jb-bootloader.blob on partiotion 4 and tf201-jb-twrp-recovery.blob and tf201-jb-stock-recovery.blob in partition 5, but nothing works. ( I have taken the file from your another post)

So finally i think that i need a bootimage and recovery image flashable through nvflash (and the right partion table number), but i am unable to find it.
[Asus  Eee Pad Transformer Prime] craigacgomez:
You need to unblob the blob to get the image or get the img file from my nandroid post...
[Asus  Eee Pad Transformer Prime] frusso:
Oh yes, i have nvflashed the file twrp-2.2.2-jb.img (The un-blob'd modified TWRP recovery) but i am not sure that i have flashed in the right partition. (i have used partition 4 for bootloader and 5 for recovery).

But this file flash also the bootloader or only the recovery ?. In the second case, how i can restore the bootloader ?

What's mean for unblob an i i can do that ?
[Asus  Eee Pad Transformer Prime] blaxican25:
the easy way to flash twrp recovery on jellybean if you have root access is to use android terminal emulator first download it then the twrp jb blob http://techerrata.com/file/twrp2/tf201/openrecovery-twrp-2.2.2.1-tf201-JB.imgdownload to the root of sd card then open android terminal emulator and type the following commands

su

dd if=/sdcard/openrecovery-twrp-2.2.2.1-tf201-JB.blob of=/dev/block/mmcblk0p4

then reboot

then i downloaded goo manager and from goo's settings rebooted into recovery and backed up my prime.
[Asus  Eee Pad Transformer Prime] eyeballer:
We've added an .img version of the -JB TWRP to our website so you can use that for flashing via nvflash.
[Asus  Eee Pad Transformer Prime] mnlmnv:
thank you so much!
[Asus  Eee Pad Transformer Prime] frusso:
Thanks, but i am unable to go in shell to run this commands, The only thing that works is wheelie and i can go in nvflash

I have downloaded the file openrecovery-twrp-2.2.2.1-tf201-JB.blob but

1) I don't know the exact commet to flash it (i have try with nvflash -r --download 5 openrecovery-twrp-2.2.2.1-tf201-JB.blob )

2) The device don't boot in recovery (don't boot at all) so i think is necessary a nvflashable cersion of bootloader

thanks
[Asus  Eee Pad Transformer Prime] promiseofcake:
You need the version that ends in .img not .blob
[Asus  Eee Pad Transformer Prime] Theshawty:
How come fastboot only flashes blobs on the Prime? Why not .img's?
[Asus  Eee Pad Transformer Prime] craigacgomez:
It's the way the Transformer series is built (it's not only the Prime, but all Transformer devices)... fastboot for the Prime actually stages the blob rather than directly writing to the partition... the AndroidRoot bootloader worked around this...
[Asus  Eee Pad Transformer Prime] Kashban:
Quick heads up: I flashed this version over the CM10 I was running before (CraigGomez version 2012-09-18) and even if CM10 has some more features I'm glad to be back to stock OS on the Prime. I missed the "ding" when attaching the dock and I missed the Asus notification add ons to quickly access sd cards and certain settings. I also achieved higher FPS with Nenamark 2 than with CM10 nevertheless how far I OC'ed the Prime with CM10. Also the deep sleep freezes seem to be gone, something that bugged me big time... I do not want to restart the tablet everytime I'm going to pick it up after some time.

So far everything went fine, the process of flashing is described in good detail and right after that I had one unexpected reboot with JB (probably because of a root app misbehaving). A welcome addition is the firmware update to the dock which came just after flashing (and connecting to the internet), something custom roms seem to miss already. Do OTA updates from Asus for the tablet work too with this ROM?

I'm going to test HDMI today, including 3D and sound, which were missing with CM10.

Asus did a good job with this firmware. Much appreciated and thanks to you guys making it happen for Custom ROM users too. Getting nvflash access in the process helps too... now I know my Prime is good until something phyically breaks it.

Your happy prime owner :)

Is it like that for you as well? Google Now rarely speaks back to me. I'm Swedish, but the system language is set to English (US), the Google Now language is set to English (US), I've set it to always speak, and not disregard bad words (foul language), and to search the web in Google.com instead of what my country uses.

Yet, she rarely speaks back. She speaks back every now and then on direct questions. If I say a random statement like: "I can count to potato", it searches the web for "I can count to potato", instead of giving a clever response like: "oh, how nice", or whatever.
[Asus  Eee Pad Transformer Prime] RonH54:
I just being sure about a few things before I Flash. I am presently on a Rooted Stock .28 ICS Prime with a NVFlash created backup,a Nandroid Backup created by TWRP2.2 and a Titanium Backup of all my Apps. I have Download from Goo Manager App the Stock deodexed ROM itself and then I downloaded the new SuperUser mentioned in the 1st Post and they are showing in my Goo Manager Folder. Now I go to Flash ROMs in Goo Manager set the Order so I am sure to Flash ROM first then new SU be sure to Wipe and reset everything and then Flash and Goo Manager does the rest? Now if anything goes wrong or I need to get back to my Original Stock .28 ICS I assume I can't use the Nandroid backup I made because of new JB Bootloaders that come with new ROM. So since I have a NVFlash backup that was created on my Windows 7 PC I would have to get Linux OS going to use NVFlash Recovery process? Is all this correct?

Thanks so much for help

A few days ago I partitioned my sdcard to NTFS rather than using the exFAT filesystem that was on it upon deliver and it seems android doesn't recognize it as an sdcard. It seems it's mounted to /removable rather than /storage/sdcard1, but I guess that's because of NTFS? Still, it feels much better than FAT32 and I've yet to come across a "this file is too big to transfer yada yada yada" message.
