[Asus  Eee Pad Transformer Prime] sturm314:
Hello,

It looks like something when wrong while following the procedure to upgrade my tf201 to Nougat ( like in the step-by-step tutorial from djibe ).

Fortunately, I had created all the img and wheelie blobs before I bricked my tab. The problem now is that I can only get the tablet into APX mode (otherwise it won't boot at all). Thus, I'm trying to recover it to factory settings and normal status with nvflash.

However, I couldn't find anywhere how to use the blobs and img files to recover the tab with nvflash, since the names of the files don't match with the nvflash tutorial (and I really don't understand much what I'm doing). Besides this, I've tried to download the zip files (TF201-JB-10.4.2.15-Unblobed.zip or TF201-ICS-9.4.2.28-Unblobed.zip), but none of both links seem to work. Could you please help me on this?

Many thanks in advance,

Sturm

A huge thank you to OP for the help reviving my old, old.. TF201 from bootloop after at least 5 years sitting around as a paperweight.
[Asus  Eee Pad Transformer Prime] georgecoat:
Hi guys,

My tf201 keeps shutting down.

I was using it when suddenly if just shut down and went black dead.

I started it, in several seconds it goes off again.

When started to recovery or to system, or even get into nvflash recovery mode it just goes off in several seconds.

The same for adb or fastboot, i cannot do anything, it just shut off in a second as soon as I get into any mode.

I have got all the files and backups ready, but my problem is that tf201 keeps shutting down and I cannot push any files to it.

I wonder if any of the experts here have seen something like this I would really appreciate any suggestions.

There's a little hole on the left side which is a reset switch. Press it for a few seconds and see if it fixes stuff. For me it fixed the weird audio and lag issues I had a few years back, even after disconnecting the battery which was weird...
[Asus  Eee Pad Transformer Prime] andrewjt19:
Does anyone have the original un-blobbed ICS and JB ROM's they could share? They links in the OP are dead. Thanks
[Asus  Eee Pad Transformer Prime] georgecoat:
Thank you very much.

I tried, unfortunately it didn't help :(

Thanks again for suggestion.
[Asus  Eee Pad Transformer Prime] andrewjt19:
Or does anyone have a TWRP flashable zip of the original ICS ROM?
[Asus  Eee Pad Transformer Prime] georgecoat:
I think this might be a hardware issue? Maybe the battery fried?

:(
[Asus  Eee Pad Transformer Prime] georgecoat:
I got it back to life!

It was the battery issue!

Just to recapitulate:

It started by shutting down the tablet one day while showing 100% battery.

Would not boot into anything (system, recovery, adb, fastbook even nvflash mode) because it would shut off after several seconds.

I tried to reinstall everything, but I could not finish any process, tablet would shut down in the middle.

I left it connected on the dock hoping it will recharge.

After 2-3 days I tried to start it, it would show red battery screen and shut down immediately. That was something new I have not seen before.

I looked around and have find out that battery is or completely fried or need to get reset.

There is two methods to try.

1. open the tablet and unplug the battery cable, then after a while plug it back and charge.

2. reset by applying paper clip in the little hole on the left side of the tablet below the Micro SD card slot and charge at the same time.

I decided to start with the second method first, since I didn't want to open the tablet.

I plugged the paper clip into the hole and taped it on the body of the tablet with the tape in a way that would apply constant pressure on the clip. I plugged it through the USB into the computer and let charging for about 5-7 hours.

Then I tried to start it into recovery.

Miraculously it worked and battery was showing 35%.

After that point everything wen smooth, I formatted and reinstalled new N 7.1.2] [ KatKiss - Nougatella #036 ] by timduru and it works like new again.

Battery is charging normally and instead of constant 100% is now showing real number that goes down when I use the tablet and up when I charge it.

Looks like the battery needed to be reset by complete discharging and then starting it up by disabling all the controls using the paper clip trick while charging on computer. That started the battery again into a new life.

Hopefully this post will help someone in similar troubles.

Thanks for support guys!

Sincerely

georgecoat

You can unblob it yourself.

Get the stock firmware here.

Get the blob tools here.

unpack blobtools and blob from downloaded zipped stock firmware in the same folder. Then start the cmd window in that folder and run

you will get

blob.LNX - boot.img

blob.SOS - recovery.img

blob.EBT - bootloader.bin

blob.APP - system.img

blob.PT- partition info

nvFlash binary/executable for linux

Hello,

Apparently the androidroot.mobi website is offline, where can I find the nvFlash binary / executable for linux (ubuntu).

Thank you in advance
[Asus  Eee Pad Transformer Prime] FlyingTaco:
Sorry for necro bumping but I found them on github:

androidroot.github.io/download at master · AndroidRoot/androidroot.github.io

wheelie in the linux tarball gave me errors but the one I compiled from source worked:

nvflash may complain about file creation, AndroidRoot generated by the CWM recovery is owned by root.

Just leaving these notes here in case someone else stubs their toe on an old tf201 they had laying around and was today years old when they found out you could get nvflash even after the JB bootloader.
[Asus  Eee Pad Transformer Prime] EpicLPer:
I don't even know if this is of any use these days? Does modern Ubuntu run on it still?

Even the optimized and ported Android versions with that Merkat or whatever it was isn't running smoothly at all anymore sadly since that hardware is just too old these days. Is it even worth trying?
[Asus  Eee Pad Transformer Prime] FlyingTaco:
Apparently postmarketOS works pretty well on these which gives it a 5.14 mainline kernel (as of this date), the only two reasons I stopped using this thing is it stopped getting security updates and the weird disk performance halting on the emmc. running pmOS off an SD card may bring life back into this tablet but I was in bootloader limbo after installing hairybean, which lead me down the nvflash rabbit hole. It's been quite an adventure but I think it will be worth it.
[Asus  Eee Pad Transformer Prime] jonafun:
I've an almost bricked TF 201 here. last known working state was in a properly running KatKiss 7.1 v39. Part of the guide involved extracting blobs in case of bricking. So I have those blobs, but I've no idea what to do with them.

Currently:

- APX mode available

- Fastboot unavailable

- Bootloader: 10.6.1.27.1

- TWRP Recovery Kang 3.2.3-0 is stuck in a loop

Last thing I tried doing with it was to convert the data partition from f2fs back to ext4. But when I executed the command, the process continued for a long time (maybe 30 mins?). I wasn't sure if I wanted to wait until the battery drained, but it seemed clear to me that TWRP was stuck at this step with no error codes in sight. I regret powering off and on again because now TWRP cannot mount the data partition, and it keeps trying to format it to ext4 on a recovery script and keeps getting stuck there. Hence, only APX mode is available.

Fastboot gets skipped every time I hold down POWER and VOL DOWN to try entering into it. But it jumps straight into recovery and that looping script on formatting a data partition that it can't even mount.

So here I am, with just these blobs created right before upgrading to KatKiss 7.1. But I don't know how to use them. I have zero familiarity with compiling stuff. I don't know what to do with the master Github page for the blob tools. But I can follow instructions step-by-step if someone could write them out for me. I can use Powershell or CMD only when someone writes out the codes for me.

Please help!

I understand those files rescue call from my TF201. I could use from another tablet? Only thus remains not enter fast boot with volume down + power. What to do?
[Asus  Eee Pad Transformer Prime] Danny-B-:
So your unlocked, but havnt ran through the NVFlash setup ? did you update to JB ? If you cant access fastboot, i'm not sure youll be able to recover really, but your better off asking in the thread i linked to above.

But to answer the question about obtaining files from another device ... No, its impossible as the files are created by your tablet using the tools and you cant use someone elses files, their useless!

[Asus  Eee Pad Transformer Prime] craigacgomez:
Yes, you can use fastboot or nvFlash to flash TWRP...

I'm no expert on this... but since the nvflash.exe is way outdated (it works great with Tegra 2 devices), it cannot do what the Linux nvFlash can do with Tegra 3 devices...

If's impossible to use someone else's nvFlash backup files since they have very specific device information like the device Chip UID, which is different for different devices... and nvFlash access can ONLY be enabled on an unbricked Prime with the ICS 9.4.2.28 bootloader...

[Asus  Eee Pad Transformer Prime] tedr108:
I'm not super knowledgible on this stuff, but I think this is correct:

These are the files that you should have created after you installed nvflash on your Prime. At least some, if not all, are device specific. If you have not installed nvflash or neglected to create these files (as recommended after installing nvflash), I do not think you will be able to unbrick. If you followed all of the nvflash install instructions earlier, you probably stored these files somewhere.

Edit: Sheesh, I was little late on this post. :o) Guess I left this thread up during lunch.

Quick question:

I ended up bricking (boot looping) my TFP by flashing the wrong TWRP image (by flashing JB TWRP, instead of ICS TWRP) and am in the process of restoring my device from nvflash.

I have downloaded the JB ROM (unblobbed) from the OP, and I wish to upgrade to TWRP 2.3.0.0 as long as I am at it. I am not sure if this will give me the JB or ICS bootloader.

So, which TWRP blob file do I rename to blob.SOS, the JB or ICS version? If I should just use the ICS ROM (unblobbed) to be safe I am fine with that.
[Asus  Eee Pad Transformer Prime] craigacgomez:
Right you are... here's some more details:

factory-config.img ==> device specific factory configurations

unlock-token.img => device specific unlock token you get when you unlock your device

blob.bin => device specific file needed by wheelie to bootstrap the device

create.bct => boot config table... I'm not sure if this is device specific...
[Asus  Eee Pad Transformer Prime] tedr108:
I posted about an nvflash recovery that I am attempting a post or two back (it appended to another post of mine, which is unfortunate). My device is bricked because of flashing JB TWRP, instead of ICS TWRP. Rather than go thru the entire install process, I'm wondering if there is some simple way to just flash the proper TWRP thru nvflash?
[Asus  Eee Pad Transformer Prime] craigacgomez:
Yes... replace blob.SOS with the TWRP recovery file (the nvFlash img version)... and if your are using the full recovery process, just renamed twrp.img to blob.SOS, replace blob.SOS and continue...
[Asus  Eee Pad Transformer Prime] tedr108:
Thanks, Craig. Still a little confused here...

Assuming I do a full recovery and use the OP's JB ROM, I would replace blob.SOS with the twrp-JB.img, right? Or, since my device had an ICS bootloader before it was bricked, would it be better to use the OP's ICS ROM instead? I was running CM10 at the time, mind you.

I'm still not quite getting if there is an abbreviated process (NOT full recovery) to simply flash the twrp-ics.img. Maybe I am beyond that possibility since my device is currently boot looping. Sorry to bother you with this stuff.

Follow up: The following command (thanks to RaYmAn) was a quick and easy nvflash fix for my invalid recovery: nvflash -r --download 5 compatible-recovery.img ... no nvflash full recovery required. My TFP was back up and running in about 30 secs!
[Asus  Eee Pad Transformer Prime] Striatum_bdr:
If you nvflash a JB ROM you nvflash a JB TWRP recovery.

Please put this file, generated by nvflash it to study!

[Asus  Eee Pad Transformer Prime] Fireplug:
If you have all the drivers installed and downloaded all the files into the same folder on your windows computer you can then open a command prompt window from that directory (one way to do this is to right click on the folder while holding down the shift key and one of the choices should be "open a command prompt here" or something like that. (Sorry not in front of my computer right now) and it is in that window that the fastboot command is typed.

Are likely in the future to develop a tool to recover and new tablets with boot problems?
[Asus  Eee Pad Transformer Prime] craigacgomez:
It's unlikely... what this tool does is amazing, but it requires flashing a specially created bootloader to create the files needed for nvflash access... without that, it's nearly impossible...
[Asus  Eee Pad Transformer Prime] 6thfloor:
I am stuck in a boot loop. I was having some serious system troubles i.e, would not mount internal sd as w/r. I could write to internal sd from my computer, but strangely enough I could not delete any files from my computer or with root explorer. I could install apps just fine though. (I think I messed something up when trying to flash cwm touch from terminal emulator).

Ok I missed a step. Doing the wipe fixed it. Great thread. My tablet seems to work again Yay.

[Asus  Eee Pad Transformer Prime] philow:
Craig, Excellent write up!!!

When doing nvFlash it is not very forgiving :)

I flashed the TWRP recovery into the bootloader partition (4) and from that point I rebooted to get to TWRP but could not.

Using wheelie --blob blob.bin would send the file 100% and get stuck. I remembered that I saw a post from Rayman to someone.

If this happens to you use (note the -r I think it fixes the bct):

wheelie -r --blob blob.bin

This worked for me. However, I could not get into fastboot after. I had to flash the bricksafe.img created in the nvFlash process using this command:

nvflash --r --rawdevicewrite 0 2944 bricksafe.img

This flashes partitions 2, 3, and 4 and will put things right for ICS again :)

Then I could reflash TWRP in fastboot or with nvFlash and get things back.

Hi guys

I just tried to do my first steps of this tutorial.. but if I put wheelie.exe --blob blob.bin in it.. there comes the message "failed to open blob file blob.bin.. why this.. I`m in the APX state on my prime which is plugged @ the pc correctly.. :mad::confused:
[Asus  Eee Pad Transformer Prime] csrabear:
Hi PipoXtreme....are all your files (wheelie, nvflash, blob.bin, etc) in the same directory? They must be for this to work. To make it easy on myself I put them in the platform-tools directory since adb and fastboot are already there. When you get them all in the same place launch a command window from there by holding down the "shift" key and right clicking. In the popup list there will be an item "Open Command Window Here". Left click this and run your commands in this window. I hope this helps you.

Hello, I just tried flashing the new JB bootloader because I wanted the JB TWRP, but when i went to flash the blob in fastboot, i flashed it to the bootloader partition it seemed to work fine but then my device froze and so i powered off and when i tried to power back on nothing happened. the screen stayed blank but the device does vibrate. I've tried all possible combinations of turning it on. including holding down all three buttons. I havent checked if i still have access to apx mode as it is not set up on my mac, but I did set up nvflash before I bricked it so will it be possible for me to unbrick from this point?

the blob "labeled tf201-jb-bootloader.blob (Blobpack of the new JB bootloader)" is the one I flashed

I flashed it in linux by booting into fastboot (volume down + power then choose usb option) and then I flashed with:

"sudo fastboot -i 0x0b05 flash bootloader tf201-jb-bootloader.blob"

terminal said it transfered 100% but then when i tried flashing twrp using

"sudo fastboot -i 0x0b05 flash bootloader twrp.blob"

the same way it kept saying "waiting for device" so i held down the power button till it shut off and now im stuck
