I was having trouble rooting. Started a couple threads here about a couple different methods I tried. It seems the nvflash method may have worked but it seems the instructions for this were removed and I didn't know I had to put the rom inside the nv flash folder. My failed nvflash showed a bunch of formatting/partioning info on pc screen in a cmd prompt before saying successful and force closing. This left tablet with a entering recovery message stuck on screen. I then went into device manager to update my apx. I had previously gone into w8 advanced settings to uninstall a apx to apply a different one but when I went into device manager my android wan't there. I notice when I hold down power/ down i get a usb sound of dissconecting followed quickly by a sound of connecting but still no sign of device on device manager. In view under device manager I clicked show hidden items. There I saw the android. I then uninstalled them but I don't see a way to install new APX and ever since my fail nvflash tf101 wont boot. Please tell me I didn't brick! And I dont have system restore on my PC. I was thinking to bring back driver:crying:
Best not to keep making new threads for the same issue, keep everything in one thread or people will stop replying / mods will close duplicate threads
well even though I didn't see apx in device manager I was able to run easy flasher and flash stock android so I'm very relieved to have a working tf101. transformer rebooted successfully
Good stuff, so long as you don't try to mess with TWRP recovery again, you shouldn't run into any more issues, you can flash customs ROMs from recovery from now on, just make sure you keep TWRP as your recovery and not CWM

I had rooted/cwm'd my tf101 when I first got it. It was running the 3.1 update at the time. I followed the pure root posts here on XDA.
Sadly I had never tested CWM, and perhaps since it went so easily I didn't really understand/read enough on CWM to understand what is happening. When I ran the 3.2 OTA (OK so I shouldn't have done that, I know now) the TF froze on the initial splash screen.
I've tried many things and read tons of posts here on XDA and other sites, and I'm not getting anywhere, but part of it is I don't know for sure what I'm trouble shooting.
I was using a dual boot laptop in Windows mode when I did the initial update. I had the drivers working and succesfully rooted my system.
What I am trying to do is restore a stock rom for now and I've tried several methods.
1) Asus download SOP - It detects the image on the SD card, checks validity of the firmware, shuts down and reboots and hangs at the first splash screen.
2) CWM recovery, if I understand this right, I Power+ vol_down. I hit the vol_up to enter The screen says
Checking for RCK. press key <Vol_Up> in 5 sec to enter RCK.
I do that and it hangs at:
Booting recovery kernel image
3) I've tried several nvflash posts out there. NVFlash does not seem to be working, I've now done this on two windows boxes. Both the one that used to work, and a clean windows XP machine I had lying around. In both cases, I can get the nvidia APX drivers loaded and the device is seen. However, adb doesn't show any devices, and from pulling apart the batch files and doing some reading, I tried nvflash -r --getpartitiontable myfile.txt and some other commands which always hang. Eventually if I disconnect the tablet - then I get a read error of some sort.
4) quick reboot - every option leads to reboot and freeze at first splash screen.
So questions that I can't seem to find an answer too.
1) If I'm connected in APX mode, should adb show a device? Like I said the PC recognizes it as the APX device and loads the nvidia drivers instead of the normal transformer MTP drivers when I do the power + vol_up.
2) Is there a simple test to use for nvflash? The device shows up, is there anyway I can confirm whether APX mode is working or not?
I'm only starting to piece together the boot process in my own head, and my guess is that niether the stock recovery image or the cwm recovery boot image is working. Would that be a reasonable assumption based on behavior? I will admit I really don't understand the boot loading process in android.
FYI, if I go through Power+Vol_down, wait for rck to skip and then boot without wiping, the TF is fine after that. Meaning as long as I don't try to update, it will work and reboot normally. Root also still seems to be working.
I tend not to suspect a driver issue, since one machine was confirmed working, it's how I got root - and 90% of the time that machine is run as linux. I almost never boot into windows. I'm pretty sure the last time I did was to root the TF.
What happened is you overwrote the cwm when you installed the new update. You can't just randomly install things once you're rooted.
If you have a B7O machine, you need to check that you have the old or new sbk. Go to the general transformer forum, and there's a thread about the new sbk locked bootloader. Follow the test to see if you have one that you can use nvflash with. If that is the case, then go to the dev forum, and look through the nvflash unbricking thread.
Thanks for the reply
First off, you're right and I should have known better. Almost nothing I own runs it's stock firmware, and I just got dumb and didn't do the full research excited for HC 3.2 goodness.
I have a B50 machine, or at least the my serial number indicates that.
I've already tried several nvflash debricking instructions, but it seems that nvflash is not working either. I have several copies of prime and the .11 release from asus. But since nvflash is not behaving as expected, all of those threads are not helping.
I do have the nvidia USB recovery device show up in device manager, but every nvflash command fails hangs at
nvflash started
[resume mode]
ADB devices shows a serial when I'm normally connected, but it doesn't show up when I'm in APX mode. I'm just not sure if the device is in a functional APX mode, since nothing actually runs, despite it showing up in device manager. I've tried googling that situation, but I can only find posts that tell me how to get it to show up in dev manager... It seems like when that happens everyone else has been fine.
WHILE GOOGLING FOR MORE INFO ON b70 - I managed to get NVFLASH working, and now I get what the first command and -r do.
3.2 Update Problem SOLVED
So look at the original post for the strange condition I had gotten into.
Somewhere along the line, the transformer had stopped responding to adb even not in APX mode.
I uninstalled PC Suite and Asus Sync. Then reinstalled only ASUS sync. ADB started working when TF was connected normally
I did not reboot my PC, win7 64 bit. Shutdown transformer, it hung at the splash screen. WHILE HUNG, I held power and vol_up until device manager showed nvidia USB recovery device
I used the stock rom replacement from tabletroms. Sorry I can't include the link as I am too new to XDA.
Got the transformer back up, set up my account, restored data. However OTA from there was not working.
So I went to ASUS, grabbed the .11 image and updates via SDCARD following the SOP instructions.
After reboot, checked for updates, and there was one. Let it do the OTA for 3.2 and now I'm back at having stock 3.2 updated TF.
I will probably root, but may not CMW this time.
Right, I searched on numerous pages on these wonderful forums, but couldn't quite find what I was looking for. So I'll try my luck here. I'll describe my problem.
My TF101 was rooted using the CWM recovery. After doing more research I found out I shouldn't be doing this. But, unfortunately the damage has already been done. After several succesful ROM installations I wasn't quite happy with, I tried one last CM10 install. That's when it all went to ****. My TF101 has been stuck on the Eee Pad splash screen for nearly 2 months now.
Normally when going into the recovery mode I can simply select install from SD card and install a new rom. Now it can't seem to mount and displays E:Can't mount \SD card or whatever.
Further on, I tried using the ADB tools to manually restore system files. Without luck. After which I tried to install the naked USB drivers using http://forum.xda-developers.com/showthread.php?t=1426502. Without luck as well. I simply ran out of ideas.
The thing is, in Device manager I do see a device called Android. But, for some reason I can't seem to install any drivers for it. I guesse this would be the first step towards getting it back to work? Or perhaps I should just get it fixed at the computer store?
Any sugestions would be more than welcome!
Easy Flasher will get you back to stock as long as you can access APX. You will lose all data however.
1st mistake read forum before you do something, coz you would have learnt abt CWM issues, anyway thatsvan old story
You got Two options, find an flash able twrp.zip and flash it using current recovery if its still working otherwise as the other guy says easyflasher
To use easy flash you need
Easy flash software from forum
Universal naked driver installed
Asus firmware and PATIENCE
Follow the steps given in the forum and you should get back a tablet running stock rom, then if you want then use easy flash to root your device again but this time use TWRP recovery.....

Right, so far I've done everything I could find. I have installed the naked ADB files and thus was able to make a connection through USB. However, I wasn't able to push any files onto the tablet through ADB commands.
I entered the (what I assumed to be) APX mode and tried to use EasyFlasher. It seemed to have worked, because a DOS screen asked me whether or not I wanted to overwrite several files. After ending the procedure I rebooted my tablet. And guesse what: CWM is still there and the tab is still stuck on the Splash screen. Also the internal SD still can't be mounted.
What am I doing wrong. I'm slowly but surely going mad here....
hmmm, easyflasher should not prompt you to overwrite anything, it should just wipe it clean. The only prompt is when you select SBK1 or SBK2.
Can you post screenshots? It'd help us understand what exactly is going on...

Right. Apparently I didn't put it in APX mode correctly. Windows asked me to install APX drivers. Which I now did. I then (I assume) was able to install the new recovery. The screen says !!!!phone update succes!!!!!. As we speak I am trying to install the stock ROM. Fingers crossed.....

I'll just sum up what I've been doing so far, because it still ain't working for me....
1) Put the TF101 in APX mode using POWER + VOLUME UP
2) Started up EasyFlasher 0.8.3 and selected "Flash Asus stock zip / Unbrick"
3) When prompted "file ..\temp\META-INF\MANIFEST.MF" already exists I selected "A(u)to rename all"
4) And then starts doing it's thing
5) Stuck at creating and formatting 15 partitions with several three letter codes.
I've ran the program three times now, but without luck. Any sugestions?~
[EDIT]Alright, managed to get it to work! Ended the tasks in through task manager about 4 times, but the 5th time was a charm. Exactly work as said. All thanks to EasyFlasher![/EDIT]
Alright, I hate being that guy. You know, the one who posts the same question as 50 other people because he is too lazy to search. But in my defense, I have spent the last three days pouring over thread after thread and still can't find the answer, so please be patient and gimme a break!
So, I'm stuck in CWM 5.8.3.4 loop after flashing Katkiss and not knowing I couldn't use the "boot to recovery" option. I've got no access to my micro SD card and my x64 Win 7 won't recognize the TF101 so I can't put my own recover zip on. Cold boot goes to the screen that lets me boot Android or Wipe. If I pick Android, it hangs (for hours). I've wiped everything and reinstalled Katkiss, Revolver, Revolution, but I have the same problems.
Is there a thread that starts from the BEGINNING of the fix and sees it through? I've found dozens of threads that say, "Just input (code), flash, and you're done!", but I guess I'm not that far along. I've bricked Dinc/Dinc2, Razrs, etc., but never had trouble fixing them like this TF101.
I've got ADB, JDK, Ubuntu, etc. since I've tried numerous times. Also, I've had no luck with the one-touch fixes. I know I'm missing something easy, I just can't figure it out.
Thank you.
Incidentally, I've tried ***http://www.transformerforums.com/fo...ry-bootloop-fix-tested-my-c10-windows.html*** , but the SDK files come in a zip, not exe and none of the files execute/install in such a way that will let me input commands. I know I'm missing something because a soft brick isn't that big of a deal.
Huh. I don't know what happened, but it involved me cleaning the screen, accidentally pushing buttons, and rebooting, and now it works. No clue, but as long as I never shut it off again, I'm set!
You're gonna need to get the PC to recognise it to fix it I'd say
Easiest way would be using Easyflasher to get TWRP recovery installed, it sounds like you have stock recovery installed at the minute
http://forum.xda-developers.com/showthread.php?t=1688012
Few people have needed new cables to get the PC to recognise the TF again, might just be needing the correct drivers though which are also linked on that page
Basically install the drivers, put the TF into APX mode,
(Vol Up & Power from powered off state while plugged into the PC)
Then run Easyflasher as admin and choose to flash TWRP (CWM is probably the reason for the bootloop, it doesn't play nice with JB ROMs)
Once you have TWRP installed, flash whichever ROM you want from new recovery and you should be good to go
I appreciate the suggestion, but that isn't doing it. I have the tab booted up and recognized by Windows, but when I try to update to a different CWM or TWRP, nothing happens. I can reboot into CWM 5.8.3.4 all day, but it won't say anything about any different recoveries I've tried to install, though the recoveries appear to be installing correctly according to the dialog given on the tablet.
I've also tried running NVflash, but nothing happens (apx drivers installed). The BAT file briefly says USB not recognized and closes.
Further, I've tried Easyflasher / one click root+recovery and I just get messages saying "ADB server out of date. Killing." The tab still reboots, but upon rebooting, it gets stuck in CWM 5.8.3.4 unless I force cold boot.
I guess the best way to describe this is to say that no matter what I do with the tab or different recoveries, I can't get rid of CWM 5.8.3.4 and no matter what I do, it default boots into CWM.
It default boots into CWM.... I think that is the key here
I remember something about that from a while ago, having to hold Power & Volume Down to boot normally, as if the OS and Recovery partitions were reversed
Unfortunately I can't remember the solution atm, but if you head over to transformerforums.com or give frederuco a PM from here or over there, Im pretty sure I remember him having a solution some time back
I shot him a message. Thanks for the suggestion.
I swear all I did was root, install Katkiss, and reboot into recovery. Is this a common problem to have THIS much trouble with such a simple process? I know now that booting into recovery can cause a loop, but this seems like way too much.
It's having CWM as your recovery when you flash a JB ROM that causes the problems
CWM & JB = Problems
TWRP is the recovery to use once you get out of this mess, good luck
I'm going to try and encapsulate everything that's going on into this initial thread but I'm sure I'll miss something.
Basically, I undertook to root my phone last night. I followed all the steps in the root thread, and I thought it worked, but then when I went to the root checker to see if I was successful. The test couldn't get a result the first time, and then failed the second time. I've known my phone to be a little temperamental when it comes to stuff like that, so I shrugged it off. Then, everything started running with so much lag that my only option was a reboot. It came back up just fine, but then, apps wouldn't open anymore. Since a reboot fixes everything, I rebooted AGAIN... except no I didn't, because I couldn't move past the white splash screen.
After some time hacking around with TWRP, system restoring my phone and the like, I finally managed to actually load the OS again. I think the phone was rooted at that time, but I don't know for sure, because this was the drawback: I couldn't install ANYTHING. My idea is that the system was rebooted into read-only mode. I tried everything I could think of to revert the system to rewriteable again, but nothing ever panned out. There was just one thing that stood out to me: "Your phone worked properly when it wasn't rooted." So, I got the brilliant idea to use SuperSU to unroot my phone. Stupid, stupid move, because now my phone can't boot past the white splash screen again. As a last ditch effort, I decided that it was time to flash the stock system to the phone. Except I probably did it wrong.
Code:
fastboot flash recovery recovery.img
Code:
fastboot flash recovery system.img
Code:
fastboot flash recovery boot.img
And where I stand now is that my phone will not boot past the white splash screen, and I can no longer access either TWRP or Fastboot.
Is my phone fooked, or can anyone save this?
#1 You can't flash system image via fastboot - it's semi-locked.
#2 You can't use 'flash recovery' command for boot and system images.
#3 For restoring your phone use SP Flash Tool - there's a thread in the General section called 'How to unbrick'.
Try it and let us know.
Cheers
Yeah, I realized afterward that if I were trying to flash the image of the system, I should not have used the "flash recovery" command because I disabled access to the other recoveries, lol. I have tried to use the SP Flash Tool in the past few days, but I could never get any download progress. I think my computer isn't making the VCOM drivers accessible to be able to flash those things to my phone. Do you have any advice on that end? Because I have seen that thread and tried those steps but I'm just not successful.
You should also read all replies to this thread - there are people who solved their problems with SPFT in their own way, that's how I've revived my phone from hardbrick.
Make sure you're phone is disconnected when you start the flash. AFTER you hit the download button in SPFT... then connect your phone...
Fantastic advice from both of you. I'm ready to revive my phone!
Okay, I think I'm making good progress on recovering my phone. I have managed to get back the stock recovery onto my phone, which I then used to install TWRP. But I'm not out of the woods yet. I used fastboot to flash the boot image onto my phone also, but when it came to the system image, I'm having a lot of trouble. The only ROM I can find for the Blu Pure XL is a 7z file. Now, I know how those work, I have 7zip and I extracted it for the system image. When fastboot was available to me, I couldn't push the system image to the phone. Now that I have TWRP and I have no more access to fastboot, I've tried to load the system file onto my phone through my SD card in four different ways:
As a .img file
As a .7z file
As a .zip file that I created by zipping up the image file
As a .zip file that was .7z, but I changed the extension
None of those methods worked. The Blu development thread doesn't point me to a zipped ROM file. One person there said that they had a backup of their files and provided a link, but those images seem to have been removed.
I'm so close, I can see this phone working again in the near future, I just need your help to get me there. Please! :'(
Edit: Also, keep in mind, I'm dumb. I don't think I really did anything super wrong, but I may be missing something ultra obvious. So if you could just keep your answers dumb for me, it would help even more.
I would stop trying to use all of the methods you are using I believe you are slightly confused by them at this time..
At this point what you have done with the random image flashing is get damaged partitions..
Get SPFT. Turn off you phone completely.
Download the full Scatter file for you phone. (put it aside).
Download a file called ALL MTK driver install. ( or something to that effect). Search for it on Google. You will find it. Run it and then reboot your PC completely.. (if you have windows 8 or higher look online on how to install unsigned drivers) --THIS IS THR BIGGEST PROBLEM PEOPLE HAVE--
Extract your full downloaded scatter image to a directory.. (you can download the Gionee E8 image if you want) it is what I am running on my Blu..
Run SPFD read the thread that they pointed out to you. Find the scatter and point SPFD.. Once it is loaded on the program UNCHECK the PRELOADER check box.. (if not you can cause problems) ..
click download and after 10 seconds or so plug in (you completely powered off) phone into the computer..
.Then wait..... and wait... It will tell you it's progress..
Keep trying it, it WILL work.. and ALWAYS unchecked preloaded when flashing with spdf...
I did follow all the steps in the original guide, and I followed the steps that you gave me too, down to using the advanced device manager to remove any MediaTek drivers from the computer and restarting the computer with disabling the driver signature verification, but when I click download, wait, and plug my phone into the computer, just nothing happens. The computer says it's an unrecognized device, and the download never progresses.
I see also that you said keep trying, but every time I try the SPFT, it never sends anything to my phone. And I don't even know how to tell if I'm missing some important step.
OK this happens sometimes. plug the phone in with device manager open.. plug the phone in when it is off..
When it says unrecognized device double click on it really fast( it will disappear fast, try it a couple of times if you don't get it the first time) then hit update driver.. point it to the MTK drivers folder (unzip the MTK drivers folder). It will pick the proper driver. on some computers it loads up so fast it has no time to recognize the driver..
After you load the drivers power off your phone again and follow the instruction I gave.. After you do this once it will load the drivers right after this..
When I double click on the unrecognized device button, it just brings up a notification that my device wasn't recognized because it malfunctioned. I don't have an option to install any drivers.
My problem is finally solved. After starting up SPFT and clicking download, I held Vol - and Power and then connected it, and that pushed the download forward. I got to the Blu animation screen, and it stayed up FOREVER, but then the next time I looked over, it was on the initial setup screen. Good as new.
Thank you guys for all your help. This forum really is an amazing place.
I am trying to resurrect my tf101. This is my starting point. Some time ago I installed cm10-20130929-NIGHTLY-tf101 into my tf101 using twrp. That installed fine but in the process something happened and I cannot boot into twrp I can now only boot into CM by holding the power button and volume up. I was not able to install gapps . Also I think my bootloader is corrupted because if I try to boot into it I just get a blank screen. I was able to install the Official TWRP App and can run it but it crashes every time "Unfortunately the app has stopped".
I am about ready to throw this laptop out because I have tried many options on this board and nothing worked. I can connect the tf101 to my computer and I can see it in device manager and I can open the laptop in file manager. I would even be willing to wipe the entire laptop and start from scratch but I don't know enough how to do this.
Any help or suggestions would be welcome.
Hi. First, I'll explain to you that for 10 years I had no contact with flashing phones. I didn't have any problems with the previous models. So I stopped somewhere at the level of the Samsung Galaxy S3-S4. Some time ago I decided that I would bring two Asus tf101s back to life and install a new KitKiss ROM on them. I set to work confidently. Turns out it's not that simple. I can do nothing. Some of the links have expired and the tips seem outdated. I can not upload a new recovery or even root the device. Strange things are happening. First of all, after turning on the device in recovery mode, after some time it goes into system boot and exits recovery. I've tried many ways and I don't understand any of it anymore. In the command line (CMD) it seems to see the device but does not want to respond to any commands, even to "adb reboot fastboot". I can do like this :
1. Ask for simple instructions for a "boy" and current links to the necessary files.
2. Look for someone who will perform a miracle and install the required Android for me.
Will someone help me?
