Just read my thread title which makes no sense at all...
Should be something like: BROKEN CWM, CANNOT FASTBOOT, CAN I ADB FLASH RECOVERY?
--
Hello,
I recently changed from a GalaxyTab 10.1 P7510 after our house was burgled and got a TF300 to replace it. I am quite savvy with changing ROMs,kernels and recoveries on the GalaxyTab, but not on the TF300. I used to own an Advent Vega so did some ADBing on it in the past, but not too savvy with ADB.
Anyhow, the problem is, my rabbit ate my charging cable and I got a new one from Ebay. The computer now does not recognise the tablet when in Fastboot mode (which I have heard can be because it is not a genuine Asus one). I can get the computer to recognise the tablet as a storage device and I can ADB to the device when the device is turned on with USB debugging enabled. I cannot get the computer to communicate with the device when in FASTBOOT. It worked with my other cable, but not the new one and I have tried uninstalling and reinstalling the driver but it still doesn't work.
The first thing I did when I got the tablet originally was to unlock and root. I am also running the official Stock Jellybean. Ever since I unlocked the device, ClockworkMod does not work properly. It will not let me make backups as it claims it cannot mount the SD card. From further research this appears to be a common fault, so I am looking to install TRWP to replace it so I can make backups and then can start to install other ROMs. I need to get it backing up before I attempt to install other ROMs as I do not want to brick it. The GT10.1 is very very easy to unbrick, however the TF seems very very difficult to unbrick, so I want to get this right!
So, what I was thinking was, can I ADB a new recovery while the device is running as I can ADB but not Fastboot, and if so what recovery should I use? (A link to one that works with JB would be great too if anyone has one). I would need to know the exact instructions if anyone would be kind enough to share please. I was also wondering if I could not do it via ADB, could I even do it from the terminal on the device?
I have searched XDA and TransformerForums for hours but not really been able to find anything definitive, so I thought I should post here.
I am using:
Windows Vista 32 for the ADBing
CWM version 6.0.2.3
JB Stock UK
On a side note, CWM returns the following errors currently when I try to back up...
BACKUP returns Can't mount SD card
BACKUP TO INTERNAL SD CARD returns SD Card Space Free 18194mb, Backing up boot image... (then it stops - it creates a folder on the internal SD but does not complete backup).
Any help would be greatly appreciated.
Many thanks,
Graham.

post in Q&A sect
i'm not a dev
but, i think you can switch recovery without fastboot
twrp for ex
http://www.teamw.in/project/twrp2/97
via adb or terminal emulator
Download the above file. Save it to the root of your /sdcard directly (internal memory only) and rename it to twrp.blob
Launch terminal emulator or connect to your computer and open an adb shell, then type the following:
su
dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4
Then reboot to complete installation.

Okrasitna,
Thank you for replying... everyone has it in for the rabbit!
I will give that a shot with the terminal. Does that recovery work for Jellybean bootloaders, I have been reading a lot about some recoveries bricking your device if it is for the wrong bootloader?
Funny enough though the rabbit is going to the vet tomorrow to be spayed to stop her destructive habbits so hopefully she will not eat any more cables!
Many thanks,
Graham.
You need to be bootloader unlocked to use custom recoveries.
If you have taken the official Asus Jellybean OTA then be sure to install the '-JB' version of the recovery for your device - and only flash roms that are based on the Asus OTA.
Device Specific Known Issues:
Be sure to choose -ICS if you have not installed the official jellybean OTA, and use the -JB if you have.
TF300
openrecovery-twrp-2.3.3.0-tf300t-JB.blob for jellybean
openrecovery-twrp-2.3.3.0-tf300t-ICS.blob for ics
tf300t or tf300tg ?
ics or jb in your device?
go to the cwm or twrp official thread and ask for a better answer
expert opinion can reassure you

I am using Android Terminal Emulator by Jack Palevich - https://play.google.com/store/apps/details?id=jackpal.androidterm&hl=en
I see from the TWRP page:

Can I install CM10 or what ROMs does this limit me to installing?
Many thanks,
Graham.
The darn thing just started nagging me with an update notice that comes back every ten minutes. I read somewhere that updating is going to stop me from doing certain advanced things, so I finally got the last push to go for either CM10 or CleanRom, depending on which one gives me the most advanced and pleasant experience.
But before doing so, it's recommended to get some kind of flash info file or something from it that doesn't come out when upgraded to the latest firmware but does on the old 4.0.3. What would be the best way to go from now on?

Your tablet will say it is unlocked in the upper left part of the screen when The Asus logo appears at boot.

Hi, if your tablet is still on stock 4.0.3 (ICS bootloader), I recommend doing NVflash first
http://forum.xda-developers.com/showthread.php?t=1894867
If you have already updated to JB bootloader it won't work.
It doesn't say Unlocked, so I guess that's why I don't see the USB option when I try to get into Fastboot?
I'm also not able to get ADB commands recognized on my win7x64... Am I doing it wrong? What's the proper method/order of events here? Isn't there a really n00b-proof version of a guide here, or is it something I should write as soon as I get out of this mess and get it working?

Perhaps I'm not really looking in the right location, but the Asus website says I need to choose an operating system and gives me no option to choose. This way I'm not able to download the apk...
Edit:
Tried clicking the links with the tab and it started the download... Device now has an unlocked bootloader. On to the next one...
Edit2:
Ah, now I get it. Pay attention to where that Android SDK stuff is being installed. Mine got installed in the folder I unpacked the installation files! So somewhere 256 folders deep on the Desktop was the right 'adb.exe' file. Make sure the tf300_nvflashpack files are in the same directory and open the command prompt there. After that I got back to the http://androidroot.mobi/t3_nvflash/ website and entered the commands. One moment please, back in a flash!
Edit3:
Now I have 5 files in /mnt/sdcard/AndroidRoot and I uploaded them to my Dropbox. I'm guessing they are the right files...
blob.bin
blob.log
bootloader.ebt
create.bct
recovery.bct
To be sure I uploaded them all.
Copied these files into the SDK folder, along with the other zipped files for nvflash so the nvflash command works to get the other three backup files.
Edit4:
Went on following the guide and checked the video to see if I was really going the right way. Finally I have all files backed up. Goddamn what a journey, but it makes you grow a pair of balls. Now on to the next hurdle, getting a proper ROM, because stock is really getting on my nerves.
So CleanRom, CM10 or Energy ROM? Should I first upgrade to JB? Without or with the popup I'm constantly getting?
Lex,
You have alot of the same questions I do/did, and I have your original post open in another window to respond to all your questions. I'm working on writing a guide for all this stuff so this is rather helpful. If I respond to a question twice, please forgive me as I'm literally just going down the list and answering em as I read em.
In your first post, the file you're referring to is gathered via NVFlash. I haven't used NVFlash yet, but what I understand is that if you use this tool it basically backs up your ICS (4.0.3) bootloader information. The newest firmware change is to Android Jelly Bean (4.1.1) and that re-locks your bootloader. Once you go to JB, you cannot go back. So this servers as a backup (again, this is just how I interpret the information from their website. I don't know how correct my interpretations are, and have actually opened a thread to ask for clarification about this program).
For the drivers, all I did was download the android SDK and install the 'android tools' and "extra - google drivers' from the list. My laptop was just recently wiped-out so I have no prior drivers installed, nor have I connected my tablet to my computer yet (just got a replacement tablet last weekend). I didn't use the universal driver or any other add-ons. Just use the SDK, it will install drivers, and then it will detect your device. I verified this by typing "adb devices" in command prompt and it detected the serial # of my device.
Within that same post, you had some confusion about ADB. It's just an executable, and you have to use the command prompt window from whichever directory it is installed to. So once you unzip the Android SDK or wherever you installed ADB to, use the command line commands "cd directory/where/adb/is/installed" to navigate to it, or use shift + right click within that folder and it will have an option to "open command prompt here" with admin privileges. That makes life a bit easier. Other people also install their SDK to C:\android\SDK or something similar, so it's less to type.
In order to determine if your bootloader is unlocked, look at your tablet in the top left hand corner when it boots up. It will say "Device is unlocked" and list a bunch of numbers (which if I remember correctly would just be the firmware information). Your device will not be unlocked until you actually download the unlock tool from asus' website and push the file via adb to your tablet and install it. That is, you have to take a very specific, very advanced overt action to unlock it. Nothing else and no one else can do it for you nor can it be done accidentally.
Next post (#8 in the thread): You are correct that fastboot will not show unless you are unlocked. I just verified this on my not-unlocked, not-rooted new tablet, and cannot enter fastboot mode. Your ADB commands wont work if your drivers are not correctly installed.
Post #10: You have to select "Android" under the OS drop-down box to find the unlocker app. As for the location of the ADB.exe, mine was found in this subfolder within the android SDK: <whereveryouunzippedit>\Android SDK x86_64\adt-bundle-windows-x86_64\sdk\platform-tools
That folder contained the correct (and I think only) adb.exe I needed.
For your last part, I think you should try out a number of ROM's to see which you like best. I've tried all the major ones (CM9, CM10, CleanRom, Hydro, Blackbean, and some of the stock rooted/de-odexed) ROMs and used Blackbean for the longest time because of how slick it looks (all black) and how easy it is on my eyes.
Make sure you document the steps you took so you can remember them in the future. I'm working on writing a guide right now and documenting my steps to go from a stock, locked, and not-rooted tablet to a rooted unlocked and custom flash tablet.
I really hope I was able to clarify some things. I am by NO MEANS an expert but I've spent many hours experimenting and think that I wish I had someone to answer my questions when I was first learning, rather than learning by mistake.
Hopefully this helps,

Hi, I use Energy rom which I find pretty good, you will need to update to JB first as Energy, CM10 & Clean rom are all JB bootloader compliant. My tab came with JB pre installed so not sure what the best way to update is but would assume since you still have stock recovery would be with OTA update (popup notice). Here is a guide to update to JB but I think this is if you have already installed a custom recovery as it looks like you flash back to stock recovery first, thats why I think if your getting update notice and still have stock recovery, go with that.
http://forum.xda-developers.com/showthread.php?t=1845377
Once you have updated to JB stock here is a guide to install custom recovery (CWM or TWRP), root & install custom roms.
http://forum.xda-developers.com/showthread.php?t=2041627
Here is link to TWRP recovery (I had issues with CWM).

Same goes for you! Tomorrow I will be trying as much ROMS as I can to see which one suits me best. Also repeating this process is the best way to learn something and since I'm unbrickable, I am going to flash the hell out of it for a few days. I'll try to post my steps and findings here so I (and perhaps others with the same trouble) can benefit from it in the future.
Also I think when you update to JB your bootloader will be locked again (new bootloader), the above guide on root, customs roms also has info and links on unlocking JB bootloader. Glad I could help, have fun :good:

It's upgrading now. Of course I forgot I lost root with the last OTA update and I forgot to make sure I rooted the thing so it was able to use the rootkeeper after upgrading to JB. I hope there is some documentation on rooting JB, because at the time this all happened root was not possible yet. It's past 1 AM over here, so I guess it's best to save this quest for later when I had some sleep.
Edit:
Just for kicks I tried 'Root Checker' and it said 'no root'. Then I saw 'Rootkeeper' was installed. Opened it up, tapped the restore button... Device rooted! Guess my memory is really failing big time... One down, # to go.
Edit2:
Installed TWRP:
Just downloaded the .blob from their website and
put it in the platform-tools folder.
Then renamed it to TWRP.blob.
Turned off tablet,
plugged in USB cable in the tablet ONLY,
hold volumeDown button,
plug into laptop holding button,
waiting...
choose USB logo,
open cmd-line in the platform-tools folder,
run command: "fastboot -i 0x0B05 flash recovery twrp.blob"
waiting...
Done. Let's see if it works...
Edit3:
At first I didn't understand how to get into TWRP (DOH!),
Hold volDown, power on, choose RCK.
Edit4:
Been having a fight with TWRP when I try to install CM10.1 (latest nightly: 20130121). Gives me an error status 7 or something...
Code:
Verifying update package...
assert failed: getprop("ro.product.device") == "tf300t" ||
getprop("ro.build.product") == "tf300t"
E:Error in /external_sdcard/CROMS/****.zip
(Status 7)
Error flashing zip ' /external_sdcard/CROMS/****.zip'
Of course, ****.zip is a long filename I didn't want to type completely here.
Will try to figure out whats wrong later today, first I'm going to try restoring the backup I made earlier, just to see how a complete backup works when the tablet is wiped back to factory settings.
Edit5:
The backup stuff is really cool! My tablet is back the way it was even though I wiped it completely!
Back to the ROM rumble... baked_tf300t_blackbean-6_jb-bl_b6.zip gives me the same error. Starting to get annoyed again... Let's try something different, CleanROM. Download is taking ages... I'm restoring again, so I can use the tablet for the rest of the day. As soon as I feel like it I will try again, for now I'm giving it 'the finger'.
Edit6:
Cleanrom is installing now. I guess CM (baked is CM based right?) was causing some trouble...
Done installing...
Wipe Cache/Dalvik...
Reboot...
Android is upgrading...
Might need to choose the small font, my screen is really clogged up with stuff. Didn't expect to keep my settings etc., thought it would be completely wiped. I'm going to restore and then reinstall with the highest DPI setting first, then I'll wander around the rom to check if I like it.
Edit7:
I think I'll stick with this one for a few days, runs fine if you ask me, maybe take the time to finally update my Galaxy Nexus to CM...
So here I am wanting to break the installed version of ICS on my tablet... I followed the general guidelines on how to root and install the new OS (Revolution). I get myself to this point where I have the zip file on my MSD card and I go to the Power up and - volume to enter into the set up and I have 2 options, one is to boot from the current version I believe that it is a linux version) and the second is the ASUS Recovery image.
I think that I have the one that I can not be changed, is this true? Am I doing something wrong (should I have the TF101 attached by USB to the computer while I am doing this)? Is it possible to change the OS by expanding the zip file into the respective folders and attempt a reboot or will this process create a brick? I am interested in playing with the Ubuntu OS on my tablet too, just to get some experience, I am the computer guy in my area and I have a lot of people that I have talked into the TF101 since it came out and they have been asking if I can figure out this.
Thank you very much for any assistance.

You need to root and flash a custom recovery before you can flash a custom ROM
Once you have done that, you can then do what you just did, only this time you will enter a recovery capable of flashing custom ROMs, the stock ASUS Recovery can not
Use this to root and flash recovery - this can flash both SBK1 & 2 version of the TF101 so no need to worry about that
http://forum.xda-developers.com/showthread.php?t=1688012
Then follow the ROMs instructions to flash inside of recovery
Also look at the serial number of your TF101, Does it start with B60 or lower (sbkv1) or b70 or higher or a c? (Sbkv2).
Is it 3G? (NvFlash won't work Sbkv3/???)
Is it a slider? (Also won't work)
Afaik it's only those 3 variants for the TF101
You can also use my PERI tool for an easy recovery install, then place the Rom zipfile you want to install on the sdcard and use the new recovery to flash it.
Dl peri (Link in my signature) then run and plug in tablet, will install recovery, then place rom zip and flash in recovery... Easy peasy.
Okay, i already rooted my tablet so i am that far, I am going to create a custom recovery now (I didn't know that, so thank you). My tablet starts with b70 so it is one of those crossover ones. I am not famillar enough with Perl to be effective with it but if all else fails I will follow your instructions and thank you, too (if i need help with that can I PM you?
I had to work the past couple of days and i have off tomorrow so I will be attempting it Wednesday and I will keep you all posted.
Now any suggestions on which OS I should start with? I was thinking about Revolution, however I am a little partial to Ubuntu since I have it a my second OS on my laptop.
thanks again for your help, again.
Hey Everyone, it took a couple of days but I finally got it to work... I used the One-Touch program for windows and it was a piece of cake. I actually had it up and running a few weeks ago and I have been running Revolution. I need to back up this edition and I am going to try out Tubuntu next week just to get some experience with the different OS's.
thanks again for your help.

Hello all.
FIrst, I am not new to this. Just let me get that out in the open. I've done custom ROMs and recoveries on four devices including two HTCs. However I'm new to Asus and this is my first tablet.
So, what is going on is that I have an Asus Memo Pad ME301T. It is rooted, bootloader is unlocked (confirmation appears in upper left corner at boot). However, it will not install the TWRP recovery when I try to push it from my PC. I try to choose the recovery icon on the bootloader, and it shows the fallen android with an error message when it tries to open. I have followed the directions and executed the proper commands from the platform-tools folder in the Android SDK. I thought maybe I could try downloading the BLOB file directly to the device's emulated sdcard and installing it via a terminal command, however I do not know what commands I should use from a terminal emulator. I'm sure it's something simple I'm missing. I am trying to install the TWRP 2.5.0 recovery because it seems to have the highest success rate, and I am currently on the 10.6.1.15.ww stock ROM.
If someone familiar with these tablets could go through the process with me, step by step, one more time (don't just link me to a thread unless it's clear, concise, and exactly what you would do in this situation) or provide the commands so I can try it from the terminal within the tablet, I would appreciate it. When I've had problems in the past it's been something simple most of the time or an extra step I need to do so hopefully one of you can tell me what I'm missing.
Thanks!

So, what is going on is that I have an Asus Memo Pad ME301T. It is rooted, bootloader is unlocked (confirmation appears in upper left corner at boot). However, it will not install the TWRP recovery when I try to push it from my PC. I try to choose the recovery icon on the bootloader, and it shows the fallen android with an error message when it tries to open. I have followed the directions and executed the proper commands from the platform-tools folder in the Android SDK. I thought maybe I could try downloading the BLOB file directly to the device's emulated sdcard and installing it via a terminal command, however I do not know what commands I should use from a terminal emulator. I'm sure it's something simple I'm missing. I am trying to install the TWRP 2.5.0 recovery because it seems to have the highest success rate, and I am currently on the 10.6.1.15.ww stock ROM.
If someone familiar with these tablets could go through the process with me, step by step, one more time (don't just link me to a thread unless it's clear, concise, and exactly what you would do in this situation) or provide the commands so I can try it from the terminal within the tablet, I would appreciate it. When I've had problems in the past it's been something simple most of the time or an extra step I need to do so hopefully one of you can tell me what I'm missing.
Thanks!

So you are trying to install twrp from fastboot ?
What command are you using ?
Thx Josh

Exactly. I open a command line on the folder, renamed the file to twrp.blob, and then I I am using the following:
ADB devices
fastboot -i 0x0B05 flash recovery twrp.blob
fastboot -i 0x0B05 reboot
I think the problem is really simple though. I think for some reason, the tablet and the computer are not communicating via fastboot. I.e. the info is not actually getting through the USB cable to the tablet when in fastboot. I have android debugging enabled and all that good stuff. So my assumption is this is a driver issue or an extra step needs done on the tablet to get the communication working. All drivers did install properly according to the PC. Maybe it's even the USB port on the tablet itself and I need to exchange it. But I can transfer files like it's a media device, so I doubt that's it.
Any thoughts?
***UPDATE***I checked settings in SuperuserSU and it turns out I did not have root enabled at boot. Enabled it and it connected to the PC as "fastboot". Commands are still not getting sent to the device. Whenever I try to send the blob, it always says "0 KB" and the device just freezes. Perhaps I need a different command or fastboot on the PC isn't initializing correctly? Or maybe there is a setting on my device that needs tweaked yet?
Thoughts?
I think I know what the problem is. Someone using the TF300T tablet had the exact same problem I'm having. Turned out it was their rooting method. I used KingoROOT despite a few murmurs of it causing issues because I was looking for results quickly not a quality job like I should have been. SuperuserSU has been behaving weirdly, as well as my USB android keyboard and a few other quirks in the OS since I did the root, so it makes sense. I will have to use the KingoROOT app and undo the root, and retry with motochopper. KingoROOT must not have rooted all directories. If that doesn't work, I will probably have to do a full restore to stock settings by re-installing a stock Asus ROM and start fresh.

Did more work and research. I did actually have the improper drivers installed. I installed them from Asus, so that is fixed. But the problem remained. After further research, it came down to version builds and numbers. I am using a version of Asus' firmware that isn't compatible with the operations I'm trying to perform. I am using version 10.6.1.15. TWRP 2.5.0.0 and newer can NOT be installed on any Asus tablet running anything less than 10.6.1.27. There is something about the bootloader, encryption or a security setting that prevents data from being pushed via a fastboot command. So I now have a Christmas project, which is update to a newer version of Asus firmware.
I found my solution here, in a thread filled with people having the exact same issue:

And directions for the fix here:

Hope my work helps someone else.
I sold my tf700 to a friend, and let him know: Do not factory reset through the Android settings. Well, He passed it on to someone else, and forgot to mention this. So, that whole TWRP bootloop scenario exists. Dug through forums, found a post where someone had made some file that resets the boot process to not go immediately to TWRP or something, IIRC, but regardless, I've got a custom-made solution, and even wrote a batch file to automate the thing (given the amount of time you have the TWRP screen before it reboots) much like the OP had.
Here's the problem: my desktop doesn't recognize the usb device when I plug in to windows. IIRC, I'd always had some kinda issue with that version of TWRP, but I never addressed that, and that fell by the wayside apparently. I don't have time to sanitize my PC and re-establish the ASUS driver environment or other advanced trickery or whatever, and I just sold my laptop prior to trying on that. My question to you fine folks is this: If I were to install Ubuntu or some other Linux-based environment, would my odds increase in terms of being able to coax TWRP to be recognized so I can flash this tiny little file over and get the thing back running? Apparently windows just doesn't want to, and short of being able to put a newer TWRP on the device, I've got to establish a usb connection somehow.
TIA :good:

Well yes and no.
Linux works much better with adb/fastboot, but if it it easier to install Linux and get it working if you have never used it compared to getting Windows drivers working - idk....

I figured that would probably be the case. Now, it's been several years since I've used Linux (Ubuntu Feisty Fawn was the last time I used Linux, and that was just to hack a first gen Xbox), but i'm a command-line based OS guy from the days of old, so I oughta be okay. I'm sure one of the various and sundry tutorials here on xda will help should I get stuck.
So, that being said, I guess I just need to install a distro and grab some adb/fastboot drivers for Linux? Or is that all built in? Is the command line interface sufficient, or will I need some GUI like xwindows (sorry if my info is horribly dated, lol.)
I'd probably better do some reading.
Nobody has any more expertise to proffer?

I cam across this live distro recently and the dev included the tools needed for adb fastboot. It works great! https://forum.xda-developers.com/an.../live-iso-adb-fastboot-driver-issues-t3526755
There also several Puppy Linux distros out there which may be interesting since they offer persistent mode already but afaik you have to download the adb fastboot binaries yourself. But that's it - no drivers needed.
With those installed you just need as terminal window. No other gui necessary

This is just the tip I needed. Big thanks!
Well, i assembled the troops- universal naked driver and minimal adb/fastboot on a fresh win 8.1 install. Bootit.ko file in my adb folder. Opened adb, plugged in tablet. Twrp starts. Hear the USB plug in noise, so adb is ready. Adb devices command, shows up recovery like it should. I then run a batch command to automate:
adb push bootit.ko /sdcard/
adb shell insmod /sdcard/bootit.ko
... as per the directions. I get this in response:
adb: error: connect failed: protocol fault <couldn't read status>: no error
on the first command, and 'no device found' on the second.
Now what?
Edit: nevermind. Added 'adb devices' to the batch file and it did it fast as anything. Lol.
New kink: adb command succeeded and i got fastboot access. Formatted 'misc' partition and rebooted-- still with the bootloop. I can still access fastboot, but that's it. Twrp always restarts. So, did SWIM bork the recovery partition too? Wondering if I should try re-flashing twrp, or downloading the original ASUS blob file and restarting from square one?
Edit:
Got impatient, started trying things. Links found thru the forums pointing to original ASUS rom blob are all broken, so i settled for starting with twrp. Downloaded freshest version from twrp.me compatible with the device and flashed it-- same result upon attempting to open twrp.
Took a break. Thought about it, and decided to fastboot erase recovery, and try flashing twrp again. Probably not a great idea... Now I get
Sending 'staging' <7210 kb>...
FAILED <data transfer failure (unknown error)>
So I guess there's a step after erasing to re-init the partition or something?
Just a note to anyone lurking - don't do stuff if you're only half-informed. You can be stupid and impatient like me and have broken stuff.
Impatience is a very bad advisor...
As long as you have fastboot you should be ok. Asus seems to have messed with their website again or they finally took the support pages down permanently.
I have a copy on my server and can upload it tonight.
Patience my friend, patience

This is too true. That's why I threw in that little blurb. :good:
I'll await your link with bated breath.
Ok here's the 10.6.1.14.10 firmware:
https://www.androidfilehost.com/?fid=817550096634791660
Don't forget to check the md5 once downloaded
You may de-bate your breath again

Debate my breath? Well, my breath reeks of Marijuana... I think it's a liberal.
Lol
Just a question: since I'll be repopulating all the partitions with the stock blob, does that affect my unlocked bootloader, or is it gonna be straight up manufacturer reset? I'm sure that's covered in the threads that address the 'buster99' process, but I need to go locate the thread. I didn't fully digest the thread as i'd yet to find the blob I could d/l, until you hooked it up. ?
No, you cannot relocate the bootloader. Flash away

Ugh, corrupt archive. ? trying to download from a different server this time.
Edit: same results w/new download. Repairing the archive didn't help either.
Asus, ya'll are killing me! Every link on the interweb linking to a TF700 firmware is broken, and all that can be found are for the 700kl.
Final update:
Found a valid download link for 10.6.1.14.8. Had some difficulties with it (revived the post on the buster99 process) -- followed as written, and had a fail on the last process <invalid state>. Being super impatient (mentioned *that* before, lol), I decided to try and reestablish twrp, as that was the original issue. That took! Flashed 3.0.0-1 (iirc), was able to open twrp, but couldn't mount system or anything. So I formatted the crap out of all partitions, converted /data to f2fs, and was able to successfully flash katkiss nougatella. Wiped the caches, rebooted, and I'm golden! 3 months later, and it finally works.
Moral of the story: don't sell rooted devices to ppl who don't understand what that entails. You can tell a person till ur blue in the face, NO FACTORY WIPE VIA ANDROID -- Odds are, they'll forget. Worked out for me in the long run (took back the 700 and gave a 201 as replacement), but i was never sure I'd come out clean on the other end.
I have similar problem, i can't even go to bootloader.
Just keep bootlooping. Is there any chance of reviving my tf700t?
If yes please advice me step by step process to do that.
Thanks
Not enough information. What can you get to?
What's your ROM, bootloader, recovery?

Thanks you already help on other thread.
It's a long story how this happened.
By the way I was running nougtell version don't remember as it happened in January.
I wanted to transfer some video files on my usb 2tb hard drive, so I did usb otg connection to my tab, i did this thing before and I use es file explorer to do the transfer, few occasions es file hang or whole tablet hang so I have to restart. But in January when this thing happened it just went into bootlooping i can go to fastboot but not recovery or android.
Then I search on many thread i couldn't find any working solution.
My cable was not detecting tab so I couldn't able to push recovery., But the same cable was ok for charging.
Then I bought new cable from eBay it took around a month to arrive.
But in mean time being impatient i tried data wipe from bootloader.
Then even i couldn't able to bootloader after that.
I know being impatient with doing something like this is not good you have to suffer.
Bootloader was latest version .14 at the end and recovery was 3.0.1
Using nogtella rom
Thanks
