Fist up when you went to PA I'm guessing you used the downgrade bootloader zip to take you back to 4.1.1 so you can follow the normal instructions for doing nvflash not the ones in here.

Once you have your nvflash backups it doesn't matter what bootloader or recovery you flash. You can always go back to whatever you want including ICS using your backups. http://xdaforums.com/showthread.php?t=1927818&highlight=nvflash

You do not have to stay on their custom bootloader to be able to use your backups. You just need the backups to use wheelie which can reinstall just about anything.

[Asus  Eee Pad Transformer Prime] joshkun:
It worked mate 1000 thanks to you :highfive::highfive:
[Asus  Eee Pad Transformer Prime] riven67:
philow flumpster thanks for the info! I had not known this. I did not have a prime during the first round of nvflash goodness and most developement had stopped by the time I had gotten mine. It has picked up a bit in the last few months or rather the hard work the devs have been doing has come to fruition in that timeframe!! lol

I was pissed that my prime had already been updated when I purchased it because I wanted a pre JB version for this reason. Well now I can still enjoy the nvflash goodness and feel free to experiment with just about anything without fear of bricking my prime. Now to actually install nvflash......thans again I still have some reading to do before I am comfortable with flashing it but will probably go for it by the end of the week.
[Asus  Eee Pad Transformer Prime] flumpster:
If it is any help to you, If your are on the 4.1.1 bootloader already then you can follow my instructions on the last page but instead of downloading "flatline_tf300.img" you would download the flatline_tf201.img instead.

Then on the first part you would type.

fastboot-windows.exe -i 0x0B05 flash recovery flatline_tf201.img

Also don't flash the Hairybean Bootloader and Twrp upgrade right at the end because that it for 2.31 users.
[Asus  Eee Pad Transformer Prime] handtector:
The nvflash process puzzled me.

adb pull /data/media/AndroidRoot doesn't work until I pulled MicroSD and restarted. I think this is an extra step for Data2SD users.

And another thing I encountered is after I flashed back to "Upgrade Hairybean 2.31 (4.2.1) Bootloader & TWRP (2.5).zip" (using CWM install zip function) my tf201 stuck at boot logo unless I pull the MicroSD. I have to reformat the EXT4 partition and reinstall 2.31 rom to get back to 2.31. I hope someone can give some insight of this.

[MENTION=3909556]flumpster[/MENTION]

Thanks for the instruction, now I have nvflash backed up and won't be afraid of testing some funky stuff on my prime.
[Asus  Eee Pad Transformer Prime] GTIM2L8:
Download the following 3 files and place them all in the folder. nvflash-tools-win32.zip , flatline_tf300.img and adb-fastboot.zip.

I downloaded the .zip files and extracted them inside the folder but a few are missing like the blob, bricksafe, bootloader.ebt, create.ebc etc.

how do I get these files?
[Asus  Eee Pad Transformer Prime] flumpster:
You get them files during the install instructions.

It talks you thru each part and what you should get.
[Asus  Eee Pad Transformer Prime] riven67:
Yes this helps actually, I have never used Fastboot and while I understand and have used command line programs going back to DOS days I have not used them often in the android world. So it is more from lack of practice using it that gives me pause. I am itching to do this but I just noticed my cable is pulled out of the connector and if moved the wrong way it disconnects so before I do it I am going to get a new cable.

I do have a related question but not really about nvflash. Once this is done I know you told me specifically not to flash the upgrade bootloader and Twrp (unless I intend to install HairyBean right away) but I can still use the Downgrade bootloader again couldn't I to get back to a regular bootloader and Twrp? I mean if there is no benefit to keeping the nvflash bootloader and no need to I'd like to go back to a standard bootloader.

Thanks Flumpster you always seem to be teaching someone something or other and we all need to give thanks for devs like you.
[Asus  Eee Pad Transformer Prime] flumpster:
Yes, because you are on the old stock bootloader (4.1.1) you can just flash the downgrade zip at the end to give you back your normal bootloader and twrp.
[Asus  Eee Pad Transformer Prime] chris13640:
Hi, worked like a charm for me :) thx flumpster

But i've just got a little question : how can i use these nvflash backuped files in case of emergency?

[Asus  Eee Pad Transformer Prime] BlackDave:
Is it normal when I flashed the Kernel Installer for it to wipe my tablet completely? I now have to restore everything. Kinda annoying.
[Asus  Eee Pad Transformer Prime] flumpster:
It definitely doesn't but I will download it again now to make 100 percent sure.

Did you install a data2sd kernel as that would look like a new setup?
[Asus  Eee Pad Transformer Prime] electorn:
NVflash question

Hello all, I have been following Flumpsters post on page 75 religiously for the NVflash files, and have run in to a little issue.

I am stuck where you enter apx mode and type: "wheelie --blob blob.bin"

the message: "waiting for device in apx mode..." , or something like that, is displayed but nothing happens, and I cannot type anything into the command window.

Am I missing a driver, or have I made a mistake somewhere? I am using a Non original cable-not sure if that might cause it?
[Asus  Eee Pad Transformer Prime] flumpster:
Update.. I just checked the kernel installer and there is no wipes included in that so it is 100 percent not that.

One thing I did notice tho was one of the mirrors was giving incomplete files so I have removed those mirrors for now so you should check the md5 of the files.

If you did a data2sd kernel tho that will explain it looking like a new machine. Install a normal kernel and you will get it all back.
[Asus  Eee Pad Transformer Prime] flumpster:
Do you have any driver conflicts in your device manager on PC when you are in APX mode? The yellow exclamation mark.

If you do then install the drivers for it from the naked drivers thread.
[Asus  Eee Pad Transformer Prime] chris13640:
if you are running win7, you have to install APX drivers manually. I had this issue too. This is due to that the APX driver isnt signed.

I was on 2.31 using the Regular kernel with data2sd. I used the kernel installer to switch to the kernel with data2sd and now everything is wiped. I can't seem to find any of my file. all gone. even my backup.
[Asus  Eee Pad Transformer Prime] flumpster:
You said the same thing twice there. Do you mean you was on a regular kernel WITHOUT data2sd and then switched to one WITH data2sd?
[Asus  Eee Pad Transformer Prime] ratman6161:
I'm getting the same symptoms except I am coming from 2.2. I'm pretty sure I'm doing everything correctly since I have successfully installed each version as it comes out going back to 1.51 - never had any problems before now. Before any one asks, yes I did flash the new boot loader per the instructions. Also before anyone asks, it is my standard practice to wipe everything - i.e. do every wipe TWRP offers before flashing a new ROM. No, I'm not trying to flash anything else at the same time or restore any apps etc. I typically wipe everything, clean install the new ROM, sign in to my google account and just let the market restore everything. Yes, I have tried again...three more times.

Anyway, to get up an running again, I wiped once more and re-installed 2.2 which is now up and running fine.

Flashing from the micro SD which is a Sandisk Ultra 64 GB. All previous versions have flashed from this same card without issues.

What I have not tried is installing using the stock kernal. I saw someone else post that that worked for them. If I do that is it likely to help? Will I lose anything other than overclocking - which it turns out I don't use much anyway?

Thanks!
[Asus  Eee Pad Transformer Prime] mathsz:
I'm copying my restore folder (titanium) I'll restore, reboot, let it sit for a while, (2-3 h), report back.

[EDIT] Still working[/EDIT]
[Asus  Eee Pad Transformer Prime] flumpster:
For people with problems can you please try the stock kernel.

Also can you inform me if you ever used hunds kernel on 2.2 in the past and if it worked.

Stock kernel goes to 1.4 max. Hunds goes to 1.7.

Stock has fsync on which is more secure with data and hunds has it off which is faster but less secure if you have a random reboot
[Asus  Eee Pad Transformer Prime] mathsz:
Ok, it just stopped working. Need a logcat?
[Asus  Eee Pad Transformer Prime] flumpster:
If I caused it it can only be framework-res or launcher2.

I have put complete stock framework on my device at moment and if that doesn't fix it I will try stock launcher.

If it sill does it after that it is an Asus bug. Let me test throughout the day but if you can grab me a logcat I will look at that also.
[Asus  Eee Pad Transformer Prime] ratman6161:
OK, thanks. I'm about to go try it again using the stock kernel. FYI, I have experimented with various test versions of the Hunds kernel on 2.2 and did not have any problems. If it seems to work on the stock kernel, I'll do a backup and then try flashing hunds over it. Can I do that by re-flashing over the 2.3 with stock kernel or should I find and flash the hunds kernel separately...or maybe its better to stay with stock kernel and wait for the dust to settle?
[Asus  Eee Pad Transformer Prime] flumpster:
There is a kernel installer in post 2 that will let you flash just the kernels.

Hunds remade this kernel not long ago to fix the advanced menu power bug. I am wondering if he messed something up when making it that only effects certain devices. Possibly voltage settings.

All the testing team have been running it fine so we can't tell what is causing it for certain people but I will let Hunds know.

If it works with stock kernel then try installing hunds again from the kernel installer and if that then fails I will make you a test zip with his old version in it to try. That will not have advanced power menu tho.
[Asus  Eee Pad Transformer Prime] Hundsbuah:
Does it reboot at the asus logo? or what problem do you have?

can you provide a last_kmsg (its located at: /proc/last_kmsg)

if it doesnt help ill make a tf201 kernel from my new beta kernel for the tf700t devices. ill give it to flumpster and he can provide it to you
[Asus  Eee Pad Transformer Prime] DarkMenTH:
I'm saying that with the external memory formatted ntfs or exfat, the device freezes and restarts always, with kernel hunds, while in fat32 row smoothly. (sd card samsung 32gb)
[Asus  Eee Pad Transformer Prime] ratman6161:
OK, here is the sequence of events:

1. Booted into TWRP and flashed Flumpter's new boot loader per post #1.

2. Just to be sure, after flashing the boot loader, I let it boot all the way back into the OS - which was still HB 2.2 at this point.

3. Back into TWRP where I wiped everything (i.e. all wipes offered in TWRP - wanting to do a completely clean install - my standard practice even when not really required). Flashed 2.3 and selected my options including the recommended Hunds kernel. No data to SD or anything like that. Just the default/recommended offered in the 2.3 install packaged.

4. Get the usual messages and finally an "installation successful" - don't remember the exact words but whatever it tells you when it worked.

5. Reboot to start 2.3 for the first time.

6. Blue line followed by Asus logo followed by the spinning wheel (the dots) under the Asus logo followed by spontaneous reboot.

7. At the next reboot it gets to the same place but this time an "upgrading android" message appears with a 1 of 7, 2 of 7, etc until it completes all 7 and then it says finishing boot....followed by another spontaneous reboot.

8. Gets back to where it was in step 6 with the Asus logo and the spinning wheel animation under it. Then it just sits there.

9. Repeated this process three times. The last time I tried it last night, I had other work to do so I plugged it into the charger and just let it run. I came back an hour and a half later and the wheel was still there spinning. At that point I force rebooted it (power and down volume) and flashed back to 2.2 wthe the surdu kernel - where it is running fine.

I'm going to try 2.3 again but this time with the stock kernel to see what happens though I may not get to it for a while.

[Asus  Eee Pad Transformer Prime] Laurentwb:
Hello,

I've installed AndroWook 2.3. It is absolutely great and I would like first to congratulate and thank the authors. Without them, our TFs would be dead since a long ago !

In fact, I moved to v2.3 from v1.51 because I've met a strange issue with the internal memory : It seems that the TF has a kind of hard time to follow what this memory is doing. For example, it seems not able to calculate the space used by the different types of files in settings>storage. A notification saying "calculating ..." remains for ever.

I had the issue in v1.51before installing v2.3. V2.3 started well but, soon after, the same issue showed up. I have to say that when istalling v2.3, I did a full wipe and formated the data space with the bootloader tool. This apparently gave a benefit but not for long.

Does anyone knowwhat it is about and how to cure ?

Thank you.

Laurent

Woah, launching google play restores the wallpaper functionality.

I was trying to download log cat. Cat logging as soon as possible.
[Asus  Eee Pad Transformer Prime] flumpster:
I would like you to try with Stock Kernel and if that works fine Hunds has just given me a new version of the Kernel for you to test.

Try stock first and repost back and I will upload something for you to try if that works.
[Asus  Eee Pad Transformer Prime] DarkMenTH:
yes, still great rom, congratulations!!
[Asus  Eee Pad Transformer Prime] kayusumi222:
Thank you, flash hund's data2sd again and works fine, the boot time is about 40s

so far so good
[Asus  Eee Pad Transformer Prime] flumpster:
me I think he is saying if he uses an sdcard which is formatted to exfat or ntfs it will work on stock kernel but crash on yours

me if he uses a fat32 sdcard then yours works

Hunds hm that can be

Hunds some kernel changes need to recompile the modules

Hunds but i don't have the source code of ntfs and exfat modules

Hunds so the modules will not work longer

Hunds I'll test it
[Asus  Eee Pad Transformer Prime] flumpster:
Just make sure you don't have files doing the same thing with different numbers in system/etc/init.d

Check for duplicate 90datasdmount with a diff number and 80blocklayoutdriver with a diff number.
[Asus  Eee Pad Transformer Prime] rege0039:
The OP mentions an app to build own profiles, but I can't see anything. Am I being like my teenage kids who can't see milk in the fridge door ?????

Thanks for 2.3 flump, running great now - hunds data2sd, dock all ok and wallpapers all good. Had one random reboot in plume widget set up but that's all.

NVflash

Hi flumpster, when I checked the device manager there were no yellow exclamation marks, and I think it said something about an apx device being connected. Sorry I am a bit vague about what the actual messages were. I did re-install the naked drivers but it made no difference.
[Asus  Eee Pad Transformer Prime] flumpster:
Try this instead.

wheelie.exe -r --blob blob.bin
[Asus  Eee Pad Transformer Prime] BlackDave:
I was on the regular kernel WITH data2sd (when I installed 2.31 i picked that one) and then i decided to switch to the Hundsbuah WITH data2sd. So this whole time I was on data2sd I just wanted to switch to Hundsbuah.

I want to note that along with the device being wiped, I no longer see the internal SD folder in the root explorer, so maybe data2sd is completely gone?

I'm going to reinstall the whole rom but I have to wait for the download to finish.
[Asus  Eee Pad Transformer Prime] flumpster:
The first thing I would try is to reflash the stock kernel with data2sd from the kernel installer to take you back to what you was on before and see if that works.
[Asus  Eee Pad Transformer Prime] electorn:
Sorted

Thanks to flumpster and chris13640 I now have my backup files. I believe chris was correct. I had to manual install the apx driver again(Yes it was windows 7)
[Asus  Eee Pad Transformer Prime] Thomasba:
Yet another :good: and thanks to Flumpster for writing the instructions and enabling Raymans hard work to give us late comers a chance to save our Primes with NVFLASH.

As others have pointed out the drivers issue can be a pain but once resolved this really is only a few minutes work.
[Asus  Eee Pad Transformer Prime] mightywhites29111971:
Does anyone have any issues with Wifi? For some reason about every 15 mins the Wifi turns itself off. Also sometimes the Wifi is on but the Prime will not connect, like the Wifi has been switched off. Is this just me or something that conflicts with the OS. Cheers.
[Asus  Eee Pad Transformer Prime] joshkun:
Check your power saver and battery settings
[Asus  Eee Pad Transformer Prime] GTIM2L8:
Found answer

I've been out for quite a while but from what I remember you had to install NvFlash before going to a JB bootloader.

I never had NvFlash before.

Will this still work on my TP and install NvFlash now?

Sorry, but it has been a long while since I have had a chance to try the new ROM and features.
[Asus  Eee Pad Transformer Prime] philow:
I just got a 64gig card and decided to play with data2sd. I have been running the Hundsbuah WITHOUT data2sd. I gparted my card with fat32 and ext4. I then used the kernel installer from the OP to install the Hundsbuah kernel WITH data2sd. I rebooted and it booted just like all other times. I expected it to boot to the setup wizard. Next I installed the Stock kernel WITH data2sd and it did show the setup wizard. Just seems that the Hundsbuah data2sd in the kernel installer may not be working right and that is why [MENTION=2794644]BlackDave[/MENTION] ended up with the setup wizard and it looked like everything was gone for him.

[MENTION=3909556]flumpster[/MENTION] I know you do not support data2sd but it seems that the Hundsbuah kernel WITH data2sd is not installing properly with the kernel installer. I have not tried to use the ROM installer but I would assume that works or there would be a ton of reports here. I am guessing most people install data2sd when they install the ROM and I am trying to add it after.

Thanks
[Asus  Eee Pad Transformer Prime] flumpster:
I just tested it and something is wrong.. I think I know what it is straight away.. Back in 5.

edit. I had missed out a permission needed for Hunds data2sd in the kernel installer but I had it in the full rom installer.

Second post now has an updated kernel installer version 2.
[Asus  Eee Pad Transformer Prime] philow:
I can confirm your change worked (Not that confirmation is needed). Also, because it is the same kernel it solves another issue I had. Encryption errors when trying to boot without the card to the old data partition :)
[Asus  Eee Pad Transformer Prime] flumpster:
Only Hunds kernel can do that with data2sd at the moment where you can have the card in and it will boot to data2sd or take it out and it will boot to internal.

I meant to make the stock kernel do it also but ran out of time before release. I will make the stock kernel behave the same for next release tho.
[Asus  Eee Pad Transformer Prime] Thomasba:
Excellent this would explain why my attempt at installing Data2sd via the kernel installer didn't work then.
[Asus  Eee Pad Transformer Prime] bklm1234:
Is it easy to switch between kernels? I want to test stock and hunds kernel to see which one does better in terms of battery life. I'm running stock now. I want to be able to flip flop between it and hunds. How do I do that? Thanks.
[Asus  Eee Pad Transformer Prime] philow:
Just use the Kernel installer in the second post. Works great!
[Asus  Eee Pad Transformer Prime] dzikusk:
How long doest it take to install this rom? I selected optional addons and pressed Instal button. Status has gone all the way to 100 % but now it tells me to me "Please wait" for more than one hour already. Is that normal that is takes so much time to get installed ? Or perhaps I should hard reset my Prime and try boot os now ?
[Asus  Eee Pad Transformer Prime] Coempi:
I haven't faced such an issue. Try to reboot manually. If your Prime doesn't boot, reflash ROM. Good luck.

Best regards, Coempi
[Asus  Eee Pad Transformer Prime] dzikusk:
I pressed power button once and then i showed that it's completed. Loading Os now :)

ROM looks great, but how can I install this on a stock tf201 running 4.1.1?
[Asus  Eee Pad Transformer Prime] McJesus15:
By reading the OP in its entirety :p
[Asus  Eee Pad Transformer Prime] dzikusk:
You have to unlock bootloader first by using Unlock App from Asus Support site.

Battery concern

Using Hundsbuah kernel for a while, everything seems butter smooth and performance of the rom is quite good compare to stock 4.1. However there is one thing bothered me a little and several other users mentioned earlier but I didn't see any direct answers (or maybe I missed it).

The battery performance is comparable worse than the 4.1 roms I was using. My prime is plugged in the dock all the time, and what I noticed is the battery of the dock will drain to almost empty over night (the prime is standing by all the time), which is only 7-8 hours. If I plug in the power, the tablet battery will never be fully charged, it sits around 94% and says charging from dock. Anyone else has similar issue? Shall I try the stock kernel?

P.S. currently running Hundsbuah kernel without data2sd,

Thanks and nice work
[Asus  Eee Pad Transformer Prime] bklm1234:
hundsbuah kernel app apk

Can anyone post the hunds kernel app apk? I installed HB2.31 with the stock kernel option. Now I have installed hunds kernel. I need the kernel app apk so I can play around with the various options. Thanks
[Asus  Eee Pad Transformer Prime] Dasdranamin:
It's impossible.

Use Kerner Installer from 2-nd post of this thread.
[Asus  Eee Pad Transformer Prime] handtector:
just unpack the rom package, all apks are inside.
[Asus  Eee Pad Transformer Prime] flumpster:
The app should have installed when he installed hunds kernel from the installer.
[Asus  Eee Pad Transformer Prime] bklm1234:
yes. I overlooked it. Thanks so much

I was floored when I came across the option "Install reverse axis fix" (think that's what it was called). Just out fokkin standing!! :good:
[Asus  Eee Pad Transformer Prime] McJesus15:
Flump tends to do stuff like that :D
[Asus  Eee Pad Transformer Prime] Nightpath:
I haven't read through the threads...but it is common when installed for Asus to do an update to the firmware?? Never saw this before on any custom rom
[Asus  Eee Pad Transformer Prime] flumpster:
It is not Asus doing it. There is firmware updates built into the rom that will prompt you to upgrade them if you are not on them.

They are very old now tho so you either came from a very old stock rom or you skipped them originally.
[Asus  Eee Pad Transformer Prime] mathsz:
Man, I'll just say it again, because I like it so much : this is a fantastic rom. and with data2sd, it's even more fantastic. can't believe how sweetly smooth the tf201 becomes.

thank you for your efforts.
