[Q] Brick - Can't get cold boot / broken cwm - Asus Transformer TF700

NB/EDIT : I am pretty sure this is due to cmupdater requiring "next boot" to recovery. Is there any way to get through this?
NB/ EDIT : Now, I can cold boot. But the flash (DD/ fastboot seems not be working. hope better news next hours).
Dear all,
I've googled this unsuccessfully and haven't found any reference in the forum to that combination of two issues...
I have flashed through CWM on my TF700T the 10.6.1.14.4 bootloader. I was previously on CM10.0 stable.
Then, don't ask me why, I tried directly from cmupdater to update to the CM10.1 nightly.
But it seems that my CWM is broken saying
"E:Can't mount /cache/recovery/command"
"E:Can't mount /cache/recovery/log"
etc...
And I can't even get a cold boot since it seems cmupdater will always point to recovery...
Do you have any ideas or reference?
Thank you a lot...

Are you using the button method or the power menu to access recovery? Read the above, may help.

Thank you elfaure, but I'm not really sure understanding.
I had a fully functional CM10.0 on my tablet. Then I used CWM to flash the newer boot loader and reboot.
Once I was in the system, through parameter, i requested an update of CM to 10.1 nightly.
It rebooted my tablet, and then, entered the CWM, but with the error messages I printed above.
Now, if I try a hard stop (power + volume up) and then a cold boot (power + volume down) then it doens't propose me the options, but directly goes to CWM. And in CWM, I can't move up and down in the menu, neither with my volume keys nor my finger. The only I can do is use power to reboot and then it come again and again to that broken cwm... Please tell me I don't need to return the tablet...

Please take what I say here with a grain of salt as I have no experience with custom ROMs or custom recoveries. But your one saving grace I think would be if you left ADB enabled on your device and have already upgraded your SDK for privileged ADB connections [required for 4.2 only] (if not then you can still do this from the PC end).
If you can get into ADB then I would think you can fix it. If not, then I think you are bricked. From ADB you can push a new ROM or recovery.

It seems I can't connect ADB as ClockWorkMod is running. But... I can't get anything else running...
I arrived to control with the physical keyboard the CWM, but can't do anything, since neither external nor internal sdcard is recognized...

At least with TWRP, a connection via adb shell is possible - either on Linux, or on Windows using the correct driver. I don't know about CWM though.

This looks like a hard brick. But I have one more idea that you can try:
Download this file and unzip it: View attachment bootit.zip
Then push it to your device:
Code:
adb push bootit.ko /
and run insmod on it:
Code:
adb shell
insmod /bootit.ko
If you are very lucky, your tablet should instantly reboot into Android.

Thank you a lot, but i was not very lucky.
It rebooted to the cwm once again.
I wanted also to share that strange point : my adb device name is 0123456789ABCDEF ...
Other ideas ? Way to try flashing a full system?

The funny serial number is normal for the recovery.
Try the procedure again and hold down volume-left immediately after pressing "Enter" in adb shell on the insmod command. Maybe you can get to the bootloader menu. If not, I'll try to build another kernel module.

That's so kind of you...
even holding the button volume left didn't worked.
I will send to you my jabber through MP if you do aggree to get this easyer. I promise if this works to make the full summary here.

I don't use Jabber or Google Talk, but I have only one idea left anyway... try this module:
View attachment bootit-bootloader.zip
Same procedure as above (unzip, adb push, insmod). It should reboot into the bootloader, from which you can use fastboot if it worked. If not, I declare your tablet finally bricked.

You're a genius, I can now fastboot and / or cold boot. When I cold boot I have my fully functional previous android. But unfortunately, with flashing with dd on block 4 the cwm, at reboot, i have exactly the same as before...
do you have a link to another bootloader ? or a way to directly flash something else ?
How can I deactivate once booted to android the fact that it boot first to bootloader?

Unless you can go into fastboot (Power + volume down) there isn't much to do but to sign a petition & wait...

For someone to come up with a solution, Like a NVflash utility for Tf300...
Yeah, but if you want add NVflash support to your tablet, it can't be bricked I'm not quite sure, but you try unpack blob from offical update, and flash all files from unpacked blob (LNX etc.).

The USB icon is gone. I sugguest downloading the correct firmware and flashing it with fastboot.
fastboot flash system blob
Download the correct system firmware, open the zip, open the zip, extract the blob to the same directory as fast boot.

4.2 bootloader does not have USB icon, just plug in USB..
i can get to the bootloader menu but only after typing adb reboot bootloader. and then i tryed flashing the blob using adb fastboot -i 0x0b05 flash system blob and then i get "sending 'system' <799764 KB>..." and it's stuck there.. i left it over 30 mins and still nothing
edit: i somehow managed to flash teh system blob (i tried with te 4.1.1 and the 4.2.2) but after flashing it did the exact same thing.. went to CWM ! i even managed to flash the TWRP.blob, and still the CWM showed up.. i can't figure out how is this even possible :| and from the bootloader menu if i go to boot the android firmware, it almost boots (it goes to the lockscreen for about 2 secs) and then reboots again.. am i wasting my time or should i throw it in the garbage ?
thanks again for trying to help me on this one i really appreciate it !

OK. The bootloader menu you now are seeing is the new 4.2 version. RCK - Android - Wipe Data(do not use wipe data).
When you get into this menu if you leave everything alone your tablet should auto into fastboot - watch the screen - upper left.
With fastboot flash the latest (proper) JB blob for your unit.
Good Luck!

You can't flash anything using adb commands. You need to use fastboot. Look in the forum for the proper procedure and follow the instructions.
Nowhere does it say type "adb fastboot ... anything...."

Here is an example of an adb command that does work to flash twrp with slight modification it will flash stock blob as well.
adb shell
su
dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4 Then reboot to complete installation.
adb reboot
I don't know where you are getting your information but you need a new source.
No one said type adb fastboot they are two different things and each has a specific structure to follow.
If the op can get either fastboot or adb to work I'll gladly provide the proper commands.
then you have the same problem as me and a bunch of other people. The bootloader freezes on the flash command, even though it will show success and stuff. It never flashes.
I can push files with ADB and on reboot the files on gone. Since we can't flash with fastboot. We have to send it in to asus at this point. I got quoted $87 + shipping.
sorry, i meant to say just fastboot. i didn't write adb fastboot.. i've tried everything you guys said, but with no success my last resort is to send it to asus for re-softing. It costs about $80 + shipping. It doesn't sound like a lot of money, but it's a price to pay for stupidness or noobness i just hope they can repair it or otherwise i'll have a very expensive thing on whch to chop onions
thanks again guys for helping me

[Q] Bricked TF300T - ADB semi ok, no fastboot, some (strange) options left

I made a really stupid mistake...
The Good Part:
...I flashed my bootloader/blob via fastboot with the latest update from ASUS (TF300T-US_epad-10_6_1_27_5-UpdateLauncher.zip), and at that point no problems. Messed around with the thread that mentioned CWM (regular and JB). Found that I couldn't access the SD Cards with CWM JB, so I tried flashing TWRP.
The Bad Part:
I read everything closely, ..... except the darn file name on the TWRP site, so I ended up flashing the TF300TG by accident, instead of the TF300T recovery.
Here's the sum of what I have left:
- no fastboot (Power + VOL DOWN won't work)
- I read about APX mode (Power + VOL UP???) but no dice there if that is supposed to work
- after i realized I lost fastboot I think I panicked and managed to erase the current firmware, so no OS currently on the device
- I think that I may have killed busybox on the device, and any chance of fully using ADB the normal way to restore ROOT/anything else
- I can get into TWRP recovery
- I can use the ADB connection, but none of the commands that would normally use busybox actually work
- under NORMAL circumstances I can't access the internal memory (/SDCard/ mount) nor can I access the external memory
- I CAN select the option to mount SYSTEM, but the contents of SYSTEM are actually my external SD Card (so I can put files on my device)
Through my hours of googling (and searching XDA) i found a thread for another device that mentioned fixing the mount points. I can't seem to find that thread, but again it was for another device, so the commands would probably be different for all the mount points anyways.
So in a nutshell:
- I can use the basic linux commands (like LS and CD), on ADB and in TWRP command line mode, but no mount or push/pull commands
- I can mount "SYSTEM" from TWRP GUI but the contents of SYSTEM are actually my external SD Card, so I can put files on the device
- I can still use TWRP to CHMOD stuff
--->>> Remaining mounts that seem in tact: (all entries are folders unless specified / anything not specified such as ROOT or SDCARD exists but is blank)

/bin (but it is empty, when I actually mount SYSTEM, it is then replaced with the contents of my external SD Card)
- /TMP/
/recovery.log (file) ... I think this was an attempt to use TWRP command button to "Copy Log to SD"
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
I know recovering from this is a major long shot, but the good news is, I have all the data backed up, so nothing is actually lost. Granted I have brick, but it's a brick that I can actually play with, and ADB still partially works. I was wondering about manually installing busybox, fixing mount points, etc, so that I could get back to a state of flashing the proper recovery and/or reflashing the bootloader to an older version.
Of course I'm noob enough to not know exactly where to start, with manually reviving busybox, fixing mount points, and using all this to actually push a bootloader or recovery without fastboot ... and I'm hoping desperately that someone will take a little pity (at least enough to see me squirm???)
I'll appreciate any advice at all to help me recover from my stupidity. I know this is a major long shot. Of course, I'm not above paying ASUS a pretty penny to fix it either, but I'd rather learn and better myself before I shell out money.
I've read a few things about letting the battery completely run out when trying to fix some cases of BRICK ... and supposedly that may get you fastboot back, but I'm holding off on that for the time being while it seems that I may still have a shot since I don't exactly have a 100% brick. My device won't stay on, I can shut it off... (i also read that device staying on all the time = brick??)

I know recovering from this is a major long shot, but the good news is, I have all the data backed up, so nothing is actually lost. Granted I have brick, but it's a brick that I can actually play with, and ADB still partially works. I was wondering about manually installing busybox, fixing mount points, etc, so that I could get back to a state of flashing the proper recovery and/or reflashing the bootloader to an older version.
Of course I'm noob enough to not know exactly where to start, with manually reviving busybox, fixing mount points, and using all this to actually push a bootloader or recovery without fastboot ... and I'm hoping desperately that someone will take a little pity (at least enough to see me squirm???)
I'll appreciate any advice at all to help me recover from my stupidity. I know this is a major long shot. Of course, I'm not above paying ASUS a pretty penny to fix it either, but I'd rather learn and better myself before I shell out money.
I've read a few things about letting the battery completely run out when trying to fix some cases of BRICK ... and supposedly that may get you fastboot back, but I'm holding off on that for the time being while it seems that I may still have a shot since I don't exactly have a 100% brick. My device won't stay on, I can shut it off... (i also read that device staying on all the time = brick??)

Hi there.
Buster99 kind of had the same problem, and he managed to unbrick it.
All credit goes to Buster99.

I have the same on my TF300t and A700 - but it seems i just managed to get my TF300t back
i tried all fastboot (reflashing recovery, boot, system etc) no dice - especially since writing system was done after 3 secs all the time.
Here how i restored my TF300T JB
download your appropriate lates firmware from Asus (WW, US etc.) and extract the zip twice so you have your blob file
install your device drivers if needed (i used Google SDK ones) (and as a Tip Win8 sucks for Fastboot stuff so try to get Win7 Vista XP for this)
Reset your device with a paperclip/needle (about 2 cm down of your sdcard slot) and hold vol-down to enter fastboot
(the folowing i did at least 10 times already but didn't erase misc)
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 flash system c:\adb\TF300t\blob (this is my path - your's may vary depending where you stored your blob) ((also this was the first time i saw the loading bar while flashing)*
fastboot -i 0x0B05 reboot
* it also took a lot longer as it should:
C:\>fastboot -i 0x0B05 flash system c:\adb\TF300t\blob

im now setting my tab up to get back to CM (which initially caused this sh1theap due to autoupdate error, same as my A700 got bricked )
hope i could help you out!

Hi,
well with wrong twrp it only means your mount points are wrong - so as long as you dont wipe/erase anything within twrp your PITs should be ok.
and with twrp loading you still be able to issue adb commands - have you tried "adb reboot bootloader" while in twrp?
you said you can't boot into fastboot with pressing the keys but using the adb command it should boot into something. Also have you tried getting to fastboot using the reset button?
Whatever you do - do not issue any erase/wipe command while in the wrong recovery.
plaese check if you can get to fastboot either via adb command or reset button. if yes - first flash the correct recovery then i would suggest to see if you can flash stock rom blob to make sure all PITs are ok. from then you can go and flash a custom rom.
and don't try fixing the mount points manually - since they have been changed around a bit by asus from every which version. only if someone has a solution for your FW version you were running you could try it - but i haven't seen one yet for the newer FWs. (i think i remember one for 4.0.4 but that would likly result in a more severe brick than now)

Successfully unbricked!!!
I can't thank you guys enough!
At the moment I'm able to run the stock 4.2.1. TWRP (the right one) is installed, and all seems to be working. When I did a backup of the stock ROM on TWRP it said FAILED up top, but everything else seemed to go ok. There were 2 other error messages too:
Code:
E:Unable to find partition size for '/recovery'
E:Unable to find partition size for '/boot'
I know usually the recovery and boot aren't messed with when running a custom recovery, so I didn't really worry about it, but I figured I'd post it here just in case.
Now I'm messing around with a few versions of CyanogenMod. I guess I'll try the "failed" backup if neither version of CM wants to work. Since I have fastboot back I can of course re-load the blob from the 4.2.1 stock update.
Seems like the latest stable CM (10.0.0) doesn't work so well on the 4.2.1 bootloader? Or should it matter? Now I'm trying the nightly (10.2) and it loaded up much quicker than CM 10.0
Thanks again guys!

Buster,
Looking around you are the master with these tablets. I have a question. I am on CM 10.2 I flashed TWRP 2.6.3.0 In my hast I flashed the TF300TG recovery. My tablet always boots straight to recovery but I can't mount anything. I discovered that I can use ADB commands and have it boot to the bootloader. From there I can select the android operating system and the tablet boots and runs as normal. I then tried to flash the correct recovery the same way through terminal emulator on the tablet. It says that it pushed the recovery fine but no change was made. I then tried booting into fastboot and flashing through the computer. As soon as I hit enter the green flashing box around RCK stops flashing and the computer says it was successful but it just sits there. I have to force the tablet to reboot. Reboots right to recovery with no change and I have to use ADB to get back to the bootloader in order to boot the tablet.
Is there another way to get recovery on the tablet? Do you think I'm going to have to redo the whole thing in order to get it working again? Not sure if it matters but in fastboot it says Key driver not found.. Booting OS

try fastboot erase recovery then reflash scannos latest twrp for kitkat from his omnirom thread. (also i think that 2.6.3.0 and above are kitkat recoveries)
this way you are at least sure that your recovery partition is clean.
also I use @scanno omni rom as my daily driver try it. (but bear in mind that without a jb backup you will have to do some work getting jb running again)

So I went into fastboot and and erase recovery. Did it. Then I tried to flash recovery and again it locks up. Rebooted and it went straight to CM 10.2 Tried flashing recovery with terminal emulator. Said it was copied. Rebooted went back to CM. Rebooted again to recovery but it went back to CM. Booted to fastboot again and selected RCK. now it says
Booting Recovery kernel image
Booting failed
Unrecoverable bootloader error (0x00000000)
It does boot to CM but now I have no recovery. OmniRom was the one I wanted to flash but at this point I'm thinking im going to have to start from square one. I just don't understand why it doesn't want to flash a recovery
Thank you for your help, you are the man

Still a no go. The only recover on there was a flashable zip file. That's why I was trying to get anything on it so I could flash that. I'm at the end of my knowledge. I've always had Samsung so I got use to odin. Never had to use fastboot. I really appreciate your help. Guess its going to have to run CM10.2 and hope it doesn't have a problem

Hi Buster,
I have a similar problem, but I cant reach the fastboot. I tried to reset and push volume down, connect tablet to PC with volume down pushed, turn off and start the tablet with the volume down pushed, but nothing. My recovery is corrupted, because it doesnt recognize any file in the SD. I tried to type adb reboot bootloader from the pc, but it says "erro: device not found".
Do you have any idea?

TF300t constantly booting into recovery

I have a TF300t that I have been doing custom ROMs on for over a year now. Not to long ago it messed up and I ended up doing a ADB side load of the the current software from ASUS to recover it. I wanted to try CM11 so I followed the directions to get the right version of TWRP installed. I noticed that it was really slow at stuff like wiping cache and dalvik, so I decided to reflash TWRP through ADB instead of a zip file.
All went well and I got into android and went into TWRP to see if everything went okay. I'm in TWRP, but I cannot do anything. Only system will mount and it says I am not rooted and wants to install supersu. If I reboot or power off it just goes back into recovery. Doing the power + vol down will not get me into the bootloader and will instead just power cycle at the ASUS logo.
Any idea on how to fix this, or did I just royally brick my tablet?

When you first reboot back into TWRP, try running fastboot commands. You may be able to reflash your recovery, or follow Buster's recovery method from there on.

hmm idk. Im guessing you flashed the wrong version of TWRP, which has ended up in a brick for most users, but they had fastboot access and could later recover it using this: http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12. You dont seem to have either ADB or fastboot, and TWRP is in a non working state. You could try reinstalling your fastboot and ADB drivers with the universal naked drivers, and then retrying ADB reboot bootloader and fastboot.
All fixed!
Here is what I did.
1.) Installed naked drivers following the guide at the link provided above. This allowed me to get into the bootloader, but I was unable to successfully flash anything.
2.) So, I followed this guide: http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
Probably lost all my user data, but worth it for a working tablet.
HUGE thanks to cmendonc2 for the help and ultimately leading me to the correct solution.

[Q] Unable to boot out of TWRP

I was attempting to install a ROM on my Transformer TF300T and I've apparently done something severe to it.
Right now I have TWRP 2.6.3.0 on it. I've apparently broken the /data, /cache, and internal storage, they're all unable to mount now. I cannot user the PWR and VOL DOWN buttons to get to fastboot anymore, it just ignores the fact that i'm holding those buttons down and only boots into TWRP. I can't choose the ADB Sideload option in TWP, it fails because of the broken partitions. I am able to connect to it in adb from my desktop, and I can push files to it, but I haven't been able to find anything that lets me fix the partitions or fastboot.
I can provide any other info necessary, but I have no idea what further to do with it.

I tried this, fastboot doesn't seem to see it.
I also tried pushing an earlier blob of TWRP, 2.5, just to see if the if it would do that much. It doesn't seem to work. It still has 2.6.3.0 installed, even though it looked like it was responding properly.
Code:

That worked. I just need to, presumably, rebuild the /data and /cache partitions, I assume?
Well, I think I've completely killed it now. I think I had originally put the wrong TWRP onto it. I tried pushing the correct one to it with fastboot, and now it will either 1) do an infinite boot loop, or 2) boot to the fastboot screen but 'fastboot devices' does not see it. I can't see what else I can do with it at this point.

Bootloop when starting android or RCK

I tried to flash a custom rom (KatKiss), and it seems that I did something wrong along the way because the tablet is stuck in a bootloop.
So I rebooted my tablet and access the bootloader ("fastboot devices" recognize my device) and try to go to the recovery (with the TWRP splash screen, "adb devices" recognize my device). Unfortunately after 20 seconds on the splash screen, the tablet reboots (tries to load my katkiss android but bootloop everytime).
Bootloader : 10.6.1.14.10
TWRP : 3.1.1.0
Since the fastboot recognize my device while in bootloader, I think that I should try to flash twrp since it seems to be corrupted somehow.
Every time I flashed a rom nothing went wrong but now that I have a problem I don't want to worsen it and would like some help on the issue.
Did you flash the rom in your current TWRP?
Something is off... Did you possibly flash the TF201 rom version??
Whatever you do - do not use Wipe Data from the bootloader!!
Reflash TWRP, format data, then reflash the rom
And report in more detail what you did
Sent from my Nexus 5X using Tapatalk
Thank you for the fast reply!
I did flash the rom with my current TWRP and only downloaded the rom version for the TF700. Below is what I tried from your suggestion:
I check that my device is recognized:
fastboot device
So I tried flashing TWRP:
fastboot flash recovery twrp-3.1.1-0-tf700t
After it succeeded, I reboot the tablet:
fastboot reboot
And as a result... nothing changes, I don't know if I should try with older version of TWRP. Seems like I only have access to the tablet with the fastboot.
That is very strange indeed. Yes, try a 3.0.2 version of TWRP and see if that works.
If not, I would flash the Asus stock blob in fastboot and start from scratch....

Not sure if this will help but I had a reboot problem with trying to load into TWRP. I posted my solution into a different thread but will toss it out here..
I just had this problem with a Transformer 201Prime. The cycle went something like this..
Power on.... get ASUS logo in middle, Tegra3 logo on lower right, and bootloader unlocked in upper left....
then a buzz... then reboot.....
So I would try the power button and hold the volume down... that got me into the bootloader but when I hit the volume up button it would give me the TWRP logo... then buzz and reboot...
After much monkeying around... I realized I would have to re install everything. Fortunately I had the original NVFLASH bloob files backed up so I was able to get into the NVFLASH commands.
Here is a great tutorial, it is for the 201 so be sure to download the correct files but the steps are basically the same.
https://forum.xda-developers.com/tra...prime-t3486237
The other problems is I had to download a bloob tool to 'unpack' the necessary .bin and .ebt files that are mentioned in the commands... I used the following link to download the tool.
https://github.com/AndroidRoot/BlobTools
I hope this helps shake loose a few answers.
Once I was able to get a working recovery I could flash an updated ROM. (KatKiss is my current favorite)
I tried to flash version 3.0.2 of TWRP and the problem is still the same.
@Unidave199 the link you put in your post points to a post that doesn't seems to exist anymore, has it been moved?
@berndblb how do I do for flashing a rom with the fastboot? any stock rom to recommend?
double post

Unidave's link would only help you if you generated your device specific nvflash blobs when the tablet was still functioning. Did you:
flash a specifically modded recovery - flash the moddded bootloader, use wheelie to generate and save your blobs, return everything to factory specs?
I highly doubt it since you would have mentioned...
To flash the stock blob in fastboot you download the Asus firmware from here: https://www.asus.com/my/support/Download/28/1/0/11/29/8/
Extract the zip twice until you see a blob and a meta-inf file.
Move the blob into your fastboot folder, discard the rest of the file
Issue these commands one by one, letting each one finish before starting the next. Some will finish quick, others may take up to 3 minutes:
Code:
fastboot erase system
fastboot erase boot
fastboot erase recovery
fastboot erase misc
fastboot erase cache
fastboot erase userdata
fastboot flash system blob
fastboot reboot
The first boot will take a while, but that should put you back on a stock JB 4.2 system.
Trash all the files you used in your last attempt and redownload the rom, gapps and supersu
Fastboot flash TWRP
Reboot
Format /data in TWRP (this will take up to 1 hour - let it finish!!), then convert /data to f2fs
Flash the rom, gapps, supersu
If you flash Nougatella remember that you have to turn on wifi right after the language selection during setup or Google framework will crash.
Spend the end of the day doing it, but it worked flawlessly! Thanks a lot @berndblb, now I can use my tablet again!

My apologies for the problem with my link, looks like you resolved it, but wanted to post a correct working link to take someone else into the full conversation and context...

Broken link ? that post isn't very old, either. ??
berndblb said:
Did you flash the rom in your current TWRP?
Something is off... Did you possibly flash the TF201 rom version??
Whatever you do - do not use Wipe Data from the bootloader!!
Reflash TWRP, format data, then reflash the rom
And report in more detail what you did

You'll need to refer to post #8. However, the link to the tf700 stock blob is broken. You'll have to search Google for one. They're out there, but it does require digging .Make sure the one you get is for the proper SKU of your tablet (US, Worldwide, JP, etc.). I completed the process myself maybe a month ago. Good luck!

I got the stock blob ww version.
Just tab doesn't stay on fastboot mode keeps rebooting.
Don't know how to do it.
Is it possible to get stable fastboot screen some how? Or just flash the bootloader to get fastboot working.
May be this noob question but I don't know how to do.
Thanks

There is one more piece to the puzzle- hold short while I dig it up.
Here it is: http://www.transformerforums.com/forum/transformer-pad-infinity-tf700-tegra-3-development/46302-guide-help-my-transformer-tf700-boots-only-recovery.html
Do be *very* careful. Read thrice, do it once. Especially if you're feeling noob-y.

Thanks for this information.
One more question,
My tab is keep bootlooping neither it stays on twrp nor bootloader.
It has blue screen of recovery that is twrp after 5 to 10 seconds it boots again.
Is this enough time to execute the commands while it is on blue screen?
Thanks

Well, that depends on several things. What I did was write a short little DOS batch file to process all the fastboot commands. So, with your batch file ready, open your command prompt (change directory to your adb/fastboot directory if it's not set in system's 'path=' environment variable) and have the batch command typed in, ready to hit enter. Tether to pc via USB, proceed to boot to adb. The second you hear windows make the USB notification sound, slap that enter key. It should just process and reset the tab and get you out of TWRP bootloop. Which is just step one.
If you aren't familiar with writing bat files for DOS, let me know.

You mean a batch file with the adb commands right? Once he can boot into fastboot he has all the time in the world to run the commands for the buster99 (description in post #8). Depending on what situation he came from before, it might be a good idea to start all fresh...
The tricky thing are the adb push bootit.ko and the insmod command. Those have to be timed just right to get executed, so a batch file might come in handy. Both commands only take a second or two to execute, so your window of 5 seconds could work. Maybe not in the same session, but they should work.
If the insmod command does not kick the tablet into the bootloader, there are 2 possible reasoons:
adb push bootit.ko did not work
the insmod command did not work
To find out if the file push worked you could add a simple list command for the contents of /sdcard/. Again - tricky, I know since you still are working with the 5 sec window, but that's what you got to work with...
That would look something like in the attached picture. So after pushing bootit.ko you issue:
Code:
adb shell ls /sdcard/
Try it with the batch file, try it with single commands... Don't give up. As long as you have any kind of adb access you should be able to solve it.
Good luck!

Again, mistake in my terminology. What I meant to say is, batch commands for the process involving the Bootit.ko- the adb portion.
Thanks for clearing that up.
@ketulharini
Anyhow, I was unable to get the process to take without having automated *every last step* of the process. Literally open the cmd window, have the command for your batch file typed in ready to go, and plug in. Hear the noise from windows and slap enter asap. That's the only way I could get it in time, and I'm a ridiculously fast typist.
