Cannot Flash anything!

Alright, so, my tablet decided to one day just cease stop working. The recovery for some reason can't flash anything now, is used to be able to flash a backup, but not anymore. It used to be able to boot past the animation, but not anymore. I cannot flash a ROM from recovery because it says that the file is bad (and please, don't tell me to check to see if the md5's are correct, they are, I've triple checked.) I've flashed CWM recovery and TWRP recovery, and TWRP cannot fix permissions, but CWM recovery can, but neither can flash a single ROM. I've tried sideloading a rom but i get this error from the CMD window
Code:
* failed to write data 'protocol fault (no status)' *
. I'm at my wits end here. The bootloader is perfectly fine, it works 100% but I can't flash a single thing from recovery. I've flashed non-corrupted recoveries, and still I cannot flash a thing.

You have flashed the latest TWRP via fastboot and it still wont flash roms? Also, what bootloader are you on?

What tablet do you have?
From where did you download which recovery for which Asus tablet.
Sounds like the recovery version doesn't match the device.

Asus Tf700 32 GB. I got the recovery from the TWRP website. In answer to the boot loader question, I have no idea how to check. All I know is that I can choose between RCK, Cold Boot, Fast boot and Wipe Data.

Have you ever unlocked the bootloader? (If not: do so by searching on Asus' site for the Unlock Bootloader Tool v7) It's a simple apk which you install and then check and let it unlock.
Only then, you can start flashing!
If you already have unlocked, maybe you sent it in (?) Or flashed an official Asus rom (?), you might want to unlock it again.
Let us know if any of these answers above helped

If you have the 4 icons that indicates JB.
Sounds like the custom recovery is not installed if your on the RCK icon and press the up volume rocker and nothing happens.

Unlocking it would require an OS to be installed, but none is installed because I was wiping to install a different ROM. I have unlocked it. In response to the boot loader, yes, it has 4 icons. So I guess it is the JB boot loader. When I go to RCK it does boot recovery but from there on its unable to open any zips besides any backups I have. When I reload a backup it doesn't install the OS, but it restores everything else.

Can you get adb shell access to your recovery?
Which ZIP are you actually trying to flash? What is the exact error message from the recovery? Try running md5sum (inside the adb shell) on the file you want to flash. Check the output of "mount". Check if /cache/recovery/log contains interesting info.

Alright, I'll have to try that when I get home in about 3-4 hours. I'll get back to you on that. Also, I noticed last night that when I was on fast boot, it would stay stuck as waiting for device on the cmd window. I'm not sure if it was my computer that didn't detect it or a new symptom. O hope its just a fluke!

Alright, here's the log from my recovery.

OK, I assumed that you're not using data2sd. 1. Make sure your microsdcard is good (reformat and recopy your backup or rom if needed),2. Boot into twrp and wipe cache, dalvik cache, factory reset, wipe system, wipe internal then finally the most important part, FORMAT SDCARD. Now reflash a new rom or try to restore from backup. I would try step#2 first. Good luck.
EDIT: format sdcard instead of wipe sdcard.

[Q] Only fastboot accessible to flash / restore my TF700

Hello,
My TF700 was on a CleanRom (2.3 i think), for a while, i decided to update.
- I installed the latest CWM (via fastboot) and flashed a Cyanogen 10.2 "stable", but my tablet freezed very quickly after successful boot, i tried some reboots and get same problem.
- I tried to install a stock ODEX root ROM, the tablet freezed at asus logo
- I flashed TWRP instead of CWM, it doesn't helped
- I tried wipe data and cache with TWRP, then my data was not accessible anymore and TWRP was unable to re-create it
- I searched on forums and found on this one that flash a boot.blob file can solve the problem
- It doesn't and now CWM and TWRP refuse to work ....
So i post here before getting my tablet completely brick.
At this point, i get access to fastboot / abd, CWM load but don't work (reboot when trying to do something), TWRP don't load.
Any suggestion to get back to a Stock ODEX rooted rom ?
Excuse my english ...

Sounds like you are on an old bootloader. Flash the stock rom from asus by unzipping the zip you download from their website and placing in the root folder of your micro sd and then go into rck from the bootloader menu (power + volume down whilst booting)
Or you could just flash it from recovery....

lj50036 helped me to flash a new bootloader, recovery, rom and nvflash to make it unbrickable
Not just helped he spent many times to explain me how it works and what he did.
He is very nice and this was a pleasure to talk with him, i'm happy that there's still person like that on this planet
see you !

I buy a tf700 with cm 11 a few days ago i am really interessted on how this steps works. I really want to make it unbrickeable, But i dont really understand how it works. I can not enter in fastboot. at least i got cwm interface when rebooting with adb into recovery.
Can u explain how you did it?

It invovles flashing a modified bootloader and the flatline recovery and then using Wheelie to generate your nvflash blobs.

Stuck in boot loop, fastboot and recovery accessible
Hello,
I'm having a similar issue and I need help! Initially my tablet was rooted with Cromi-X 5.4. Then I decided to try Crombi-KK.
Here is what happened:
- Updated TWRP recovery
- Did a full wipe as recommended
- Flashing got stuck at the Crombi-KK loading sign
- Tried to reflash but TWRP wasn't detecting data partition anymore
- Instead installed the other recommended recovery CWMR.
- Flashed Crombi-KK, it worked. Played around with it for a few days, it was wonderful, fast and responsive.
- Battery died out and when I turned it back on I got a UIDs system inconsistent error.
- I found online many recommendations to reflash so I tried to do that
- Since then I'm stuck in a boot loop. I see the initial "bios" Asus logo then it restarts over and over.
- I am able to access bootloader and recovery
I've tried reflashing the asus stock blob. I've tried wiping the data through CWMR but it starts working and then it restarts. I don't know what to do anymore, so if anyone can help me, I would really appreciate it!
Thanks

Which recovery and bootloader version do you have now?
A (for KK) outdated bootloader seems the most likely culprit.
You can try save the recovery log when you flash or grab a logcat of the bootloop, but probably it'll only tell you that the recovery cannot mount /data.
Determine that you are on the correct bootloader, if not update it. If you're lucky the tablet will start right up. If it doesn't, formatting /data is the only way I know to get it back. Not just wiping - formatting it. You will loose everything on internal SD, so I hope you have a nandroid you can restore from later.
If you use TWRP 2.7+ be aware that formatting can take more than an hour. Let it finish!
For good measure, download CROMBi-KK again, check the md5 and then flash that file.

I'm on 10.6.1.14.10 bootloader which I think is the latest one
I have 6.0.4.7 CWMR
I'm trying to format data completely but when i do it in CWMR it starts and then the tablet reboots on it's own after a couple of minutes.
How can I retrieve the logs, I never had to do it before.
Thanks for your help

Mhh, getting a little more complicated.
Your BL is ok...
What do you see in CWM when you go into Mounts and Storage? What is mounted?
The recovery logs are under Advanced > show logs.

I'm at work now but from what I remember the only thing mounted was the cache. I'll double check tonight. Do you think there's any hope or I have a brand new paper weight?

Can you fastboot flash twrp?
It's much much better than CWM, has its own terminal and will be easier to offer the correct format command.

So I flashed TWRP and when I go in mount/storage everything is selected except for system. Should I do a format data from the wipe menu before flashing crombi-kk again?

To be in the safe side, yes, that is what I would do. TWTRP 2.7.+ takes a long time to format and it may seem the process got stuck. Give it at least 90 minutes to finish.
Then reflash CROMBi

I'm back up and running !!!
This time installing TWRP, everything was mounted (maybe my previous flash before CWMR wasn't good), did a format data, waited until it was done, flashed latest Crombi-KK and going through setup now. Hopefully won't have the same UID issue on next shutdown. I didn't enable fsync or journaling so hopefully it won't happen again.
Thanks both of you for your help!

Good deal! Happy for you!

No OS, TWRP fails to flash .ZIPs

Hey guys,
I'm having some trouble with flashing a new ROM and now I've soft-bricked my device.
I was trying to flash from CROMi to CM11 so I wiped data, cache, dalvik using TWRP. But when i tried to flash CM11 M9, i would get the "failed" error. I tried flashing other ROMs but same result - "FAILED".
So I thought maybe it was the recovery. I downloaded a CWM recovery (in .zip) and tried to flash it. FAILED!
I tried to restore my device using the "Recover /Downgrade from Jelly Bean to ICS/Clean Factory Restore with custom recovery" method from this post. Since it is basically flashing the stock ROM, naturally it fails.
Now I'm out of ideas. How can I save my tablet?
Thanks for your help guys!
PS: I'm trying to install CMW via fastboot. When I press power + vol down, I get to the screen with "RCK, Android, Data Wipe"; I dont see the USB icon. How do i boot into fastboot?

You are in fastboot mode when you see the three icons. Read the tiny script.
Except for CM11 M9 you did not give us anything to work with.
Give us the version numbers of:
- CROMi-X you were running
- your bootloader
- your recovery
My best guess is you are trying to flash something with an incompatible recovery, but that's just a wild guess.....
And stop flashing willy nilly until you know what's going on. You can brick this tablet if you try hard enough, you know....

Hey bern,
Thanks for the reply.
My tablet got really slow so I decided to flash CM 11 M9, which is what I use on my Note 3.
I'm running TWRP 2.6.1.0. Not sure which CROMi I was running because I can't boot into Android. I did a data wipe prior to (attempting to) flashing CM11 and now it boots straight to recovery.
I read that TWRP is not compatible with CM11 and that I should flash CWM. But TWRP fails when I try to flash anything so I'm thinking I should attempt ADB sodeload or terminal command and load that way?
Thanks again
Edit: I downloaded CM11 M9 for tf700. I also tried various nightlies in case my original download was corrupt. It ends in failure

Hi berndblb!
I'm also having this problem and I see that you're quite active in the TF700 forum that you could help me out. I wouldnt say I'm an expert but I have tinkered with phones (mostly Samsung and Nexus devices) in the past so I am familiar with ADB, terminal commands, flashing ROMs, etc.
I'm running TWRP 2.6.1. I was running CROMi-X (not sure which version) and wanted to flash OmniROM. However, TWRP would show "error flashing zip" and "failed" in red. I tried flashing a few other zips including TWRP 2.7.1.1 and CWM (I readTWRP is not compatible with some ROMs) and I would still get the error and "failed".
So now, I can't boot into the OS to flash a recovery via fastboot or via CWM Rom Manager, nor can I flash anything in TWRP. I also attempted to flash TWRP 2.7.1.1 via terminal command
HTML:
dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4[HTML]. I loads but it doesnt install when i restart my device.
What do you think I should try next? I'm getting pretty desperate at this point. Is my device bricked-bricked or can i salvage it?
Thanks!

Exactly.
I also would like to know how you performed the wipe you mentioned. The tablet booting only and straight to recovery would indicate that you used 'Wipe Data' from the bootloader???
Also, do not use ROM Manager. It does not work well with the Transformers and can cause a lot of problems.
I have a feeling another user is going to benefit from your excellent unbrick guide, Josh...

twrp or CWM saying cant mount any partition TF300T

hELLO,

I already enabled USB debugging and everything else in tablet settings but I am unable to mount anything or format anything from TWRP or CWM.

If your fastboot still works, please try Kang TWRP 2.8.7.2 from here: http://forum.xda-developers.com/transformer-tf300t/development/recovery-twrp-t3046479.

if the other recovery does not work, you would probably need to reflash stock rom from the asus website, this is due to recovery not being able to identify the partitions without a full boot, if you wiped it from bootloader the whole partition table is messed up and you want to reflash that by using the stock rom. If you need any help on that just pm me.

I have the exact same problem. Not sure about fastboot as so far it has not installed anything. I have twrp 2.5.0.0 .... adb does function and have actually installed KK 6.0 and works fine, but on restart it is back to recovery and no OS.Any help appreciated.
using fastboot all I get is waiting on device and a blinkng cursor.
How can I get Kang twrp on the tf300 with adb commands?

Sorry to sort of hi-jack the OP thread, but my problem is very similar. Here is where I am now tablet sitting at Starting fastboot usb download protocol ... 3 icons with RCK blinking. I ran the following From my sdk platform tools folder.
adb reboot bootloader
it was followed by;
" daemon not running. starting it now on port 5037"
"daemon started successfully"
I then ran the following:
fastboot -i 0x0b05 flash recovery twrp_tf300t_kang_2.8.7.2.img
it was followed by:
sending 'recovery' (7126 kb)...
followed by a white blinking cursor and it just sits there,
Same results if I run it all the same except substituting the blob file instead of the img file.any ideas?

Many Thanks
Many Thanks, go out to gs-crash-24-7 as well to the forums here at XDA, I now have my tf 300 back up and running on the stock JB 4.2.1 rom. Still isn't recognizing my Micro SD card, but that is a problem I think should be easier to solve.
Again, many thanks all.
Took forever to get it to be recognized as a fastboot device with windows 10, but once that happened ( I won't lie, I erased everything many times) well that and me switching to a little 3 ft cord (after so many attemps at adb>fastboot flash staging blob) it is going for now.
Good advice below if your TF300T seems bricked.

TF300TG after flash nougat 7.1 not boot

Goodmorning everyone
I have a problem on my TF300TG which I picked up from my drawer after a while
I upgraded to 7.1 nougat following the instructions given in the letter (very clear) but now my tablet does not start the system, I explain better:
it turns on and the writing unlock remains The device is unlocked with the ASUS logo in the Center but does not start.
I can go back to recover twrp at any time and reflect what I have repeated several times even with different versions but I always have the same problem.
I can also re-revise the original flash blob and start again

First of all format data through Kang TWRP recovery. It may take until one hour. Be patient. Let it run. After that install rom, SUSuperuser and pico Gapps in one run.

Not boot again

I just finished the procedure that you suggested that it did not return me errors but does not boot.
just restarted of the recovery mode updates the twrp restarts and remains nailed on the Asus screen if I want I can restart in recovery.
Any other suggestions?

Yes, you should do carefully a Buster99: https://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
This procedure brings you back on a clean stock rom Android 4.2 Jelly Bean. Then you have to flash Kang TWRP firstly.
PS: Attention! If you restart in recovery with the 3 icons, never touch the third one in order to "Wipe Data". It bricks your device!

The factory reset has been done correctly the system has restarted correctly after reinserting the nougant yet the system does not boot the only thing that has changed and that now reboots into the loop by returning to the asus screen repeatedly

It seems there has been a big misunderstanding by you. I advised to format data through Kang TWRP, but you did a factory reset, didn't you?.
Too many people mix up wipes and formats. Format only data means, not factory reset, not wipe - you format it ext4, then convert it to f2fs. Formatting in Kang TWRP takes until 1 hour. If it went faster you did not format. Kang TWRP does a deep format that rewrites everything in the partition. No moldy leftovers.
Now your device is in a boot loop, but not bricked. So doing a Buster99 is the only way to solve the problem. If you need help with fastboot, head over to the General section. Download and install "Minimal ADB and Fastboot" on your PC.

Excuse me surely I did not understand here now I follow your advice step by step.
Now I'm running a buster99 but I don't need ADB, I already have a fastboot working.
PS that is I'm starting fastboot not from adb but from a folder on my pc that is executing the buster commands
Then what do I reinsert the right Kang bootloader?
Excuse my ignorance

I have already inserted this twrp tf300t kang 2.8.7.2.img, through fastboot do I have to do it with the linux procedure?
the system now has boot recovery and starts normally with the old system.
Now that I do I have to delete the given partition or do I flash the three roms?

I'm sorry, but it is not easy to understand what you did. As far as I know your device is on stock rom Android 4.2 Jelly Bean. Correct?
The next step should be to flash (not insert!) "twrp_tf300t_kang_2.8.7.2_signed.zip" via fastboot. The command is: "fastboot -i 0x0B05 flash recovery foo.img". Replace foo.img with the recovery image name! Did you?
If yes, you may start the device into recovery. Kang TWRP should start. After that install through TWRP Nougatella #39, pico Gapps and Super SU from the external memory of your device in one run. That's it!
Please pay attention you did download the newest versions in post #1: https://forum.xda-developers.com/transformer-tf300t/development/rom-t3453702 !

Sorry I'm using google translate
So far I have flashed the recovery twrp_tf300t_kang_2.8.7.2.img.
I restarted in recovery mod TWRP and I installed the 3 zip in sequence through sd card
KatKiss-7.1_TF300T_039.zip, open_gapps-arm-7.1-pico-20200325.zip, SuperSU-v2.82-201705271822.zip all OK
I ran Wipe cache / dalvik
I restarted
performed a first start where the bar under ASUS quickly colored blue
It has restarted
but later stuck on ASUS. I don't know where I'm wrong

From the fact that you have not replied to my last message, I think we have given up.
Just one thing I'm curious to know are there versions of this Tablet with different hardware or different firmware (bios) you can update? I don't know I thought even if I had to have a rom already cooked and functioning on an equal tablet I could shoot it in a single flash

I'm sorry, but I also don't know where have been wrong? How should I reply after so less information about the situation. There are many different possibilities.
Hopefully you have a backup of the system through TWRP after finishing the Buster99. If so, please start the TWRP recovery and restore the backup.

Sorry but once done the Buster99 procedure I don't need to do a restore of the Backup since the tablet restarts regularly with the original system I didn't perform any backup I didn't need it
