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.

I just get stuck at waiting for device. Is there a section I am supposed to be in? Or do I do it from the home screen for twrp? I checked device manager and it does have Transformer listed in other devices.

Use the reset pin on the SD card side and then reboot back into TWRP and try with "fastboot devices"

As in the command:
Code:
fastboot devices
Else you could try:
Code:
adb reboot bootloader
from the ADB in TWRP and then try fastboot commands.

It's not finding anything and ADB sideload fails. I'm doing the fastboot commands from the fastboot folder I have been using with other fastboot stuff for the TF300.

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.

TF300T 4.2 TWRP Error

Hi XDA,
I am a complete noob, and this is my first time posting, so bear with me.
Some time ago I rooted and unlocked my TF300 with SuperSu. Recently I wanted to upgrade to 4.4 kitkat. However, my Tablet was stuck at Andriod 4.1 because of the the unlock.
I went to manually update my TF via the Asus website. I installed the 10.6.1.8 using my TWRP 2.5, and Oem 4.1 OS. Installation worked just fine. After install, I booted up and I had 4.2 with everything working correctly.
Next step was to install TWRP 2.7.0.1. I reset my TF and went into RCK to see something went wrong when updating.
My TWRP will not load, and I get the Android on his back with the red triangle when I try to enter RCK.
Thanks in advance!!

I managed to install 10.6.1.27, but it did not change anything with my boot loader.
I downloaded motochopper, but that didn't seem to work, just told me my abt was out of date. SuperSu isn't working now either, "No Binary, There is a problem."
How do I install TWRP 2.7 with no boot loader? Please help.

Most people just install TWRP via fastboot like
Code:
fastboot -i 0x0B05 flash recovery twrp.blob
You could try using other root methods, like Framaroot or Kingo. I think Kingo was reported to work on the latest stock version.

I will look into that, but I am pretty sure I was already rooted, unless losing my boot loader means I am no longer rooted.
Another thing, I can't find a twrp.blob for 2.7, just a zip. I have one for 2.5, but that is useless because I already have 4.2. I also have not been able to find a working link to fastboot.
If anyone could give me a link to the fastboot or a link to a tutorial, that would be amazing. I have done my research, but all the lingo and different methods can be mind bending.
Thanks

You can get the img (which substitutes as a blob) from extracting it from the TWRP 2.7 zip file.
1) You will need ADB and fastboot for this: http://forum.xda-developers.com/showthread.php?p=42407269. I would suggest keeping the tablet at least at 50% battery.
2) Install Naked Drivers. This may be optional for you. If you can proceed to the next step without, you won't need it.
3) Enter fastboot by rebooting and holding down the power button. TF300 enters fastboot automatically since this is 4.2 BL.
4) Next we need to enter a command. In side the ADB folder, hold shift and right click. Then select Open command window here.
first check to make sure the device is connected:
Code:
fastboot devices
The device serial number should be listed.
enter command:
Code:
fastboot flash recovery twrp.img -i 0x0b05
Blue bar on device will fill. Be patient.
5) Reboot the Device back into Android. This is an important step.
6.) Go back into TWRP and install what you want.

You are amazing. I will give it a try tonight and report back!

Installed adb fastboot. However, my device does not automatically go into fastboot, I still have to hold down the volume key.
Once I am in fastboot usb (with the 3 icons), I fastboot successfully and get the serial number, then when I type the 'fastboot flash recovery twrp.img -i 0x0b05' command I get this error: cannot load 'twrp.img' : No error
I am attemping to use the 2.7.0.1 twrp from the 4.4.2 page. I have extracted the recovery.img (tried renaming to twrp and left it the same) and placed it in the root of both my external and internal sd.
I have now tried it with .zips .img .blob and I receive the same error everytime. Not sure what I am doing wrong now.

Put the twrp.img into your ADB folder, where you installed it. Then run the next command.

Awesome! Worked like a charm. twrp 2.7.0.1 installed perfectly.
Then I tried to flash the cyanogenmod. Said it installed fine, but it just gets stuck on the loading screen...

I am trying to do exactly what TallMilk is doing...put Cyanogenmod on my tablet. It is my understanding that I have to unlock my bootloader though? Which I have tried doing a million different ways with the Asus Unlock tool which always gives me an error.
If I follow the instructions posted above I will be able to flash Cyanogenmod without unlocking my bootloader?

Finally got it to work. I had to do a wipe first, read about old roms interfering with new installations.
SilentSpartan, I used SuperSU last year to root and unlock my tablet when it was still a 4.0 android to flash to 4.1. This recent update was from 2.5 TWRP on a rooted device running 4.2. When I installed 4.2, it blew away my TWRP, and I had to flash the new TWRP 2.7.0.1.
That flash from OEM fastboot to TWRP 2.7.0.1 is what I needed help with.

You're going to have to unlock no matter what. Did you try both v7 and v8 of the unlocker and calling Asus Support to tell them to put your serial number back into the database (get a manager)?

If you are able to go to recovery(which you should be able to do), download any custom ROM of your choice like PA, CM, SLIM etc.. flash that rom by following the Installation instructions in the thread. YOu should be able to get the phone back to normal. And if you want the stock ROM, then download the stock files and flash it, you might loose custom recovery, then follow the same things you did to get TWRP in the first place.

I would if I could. The problem is I formatted the whole phone which included the internal storage too. My CM Rom is in the internal storage and it's already deleted. I tried to connect my phone to the pc so that I could transfer a rom into it but failed cause my pc won't recognized my phone as the media transfer devices. It's only recognized my phone as fastboot falcon s. I've installed Motorola Device Manger but it's also failed. I also tried to install using adb sideload but I got device not found error and my phone doesn't listed in the device attached after I typed 'adb devices'. For the OTG and memory card reader method I haven't try yet because I don't have any of it.

What does it say when you try
Code:
adb devices
or
when you reboot to bootloader with phone connected and type
Code:
fastboot devices
If it shows a device for fastboot devices then follow this to flash back to stock. Make sure you download the right stock firmware for your phone.

It seems like you dont have fastboot files. Follow the same link that i posted in the previous one. It has portable adb & fastboot files. Download that and then follow instructions. You should be able to get to fastboot. Once you are there the job is almost done. Hope it helps
Edit: Here is the link to download and install the minimal adb & fatsboot files

I've followed all the instructions but my phone still not rebooting. When I try to reboot it, it only show me the warning of unlocked bootloader screen, black screen, warning of unlocked bootloader screen then dead android screen. What should I do now?

It means your phone is in fastboot mode and recognised by your PC. Next you'll have to "fastboot flash" the necessary files to install a recovery and a system, and you should be good to go.

Few weeks back I ****ed up soft bricked my phone had kindda same issue when I switch my phone on I get a dead android logo. Gave to the service center in India and got a replacement a new xt1033
P.s I was trying to root and my warranty was void still got a new one try your luck bruhhh

Hey, I've done all of the flashing instruction from the xda forum link that you gave me. My problem for now is, why is my phone not rebooting? The only thing that happen after the flashing is my phone only show the 'warning bootloader unlocked' and the dead android with red triangle screen. It won't boot into the stock rom that I've flashed. The stock rom/firmware that I used is correct. Please help me.. I really need to use my phone.

K there's a resolve for this...Provided that you haven't ****ed up your phone by making it hard bricked...
1 - Get a freaking rom and sideload it through TWRP to boot into system...
+ Download a ROM
+ Put it in the same folder as ADB and Fastboot and rename it to something easier that you can type exactly (ex: 1.zip, backup.zip...)
+ Shift + Right Click at a blank field in the window
+ Choose Open Command....
+ On TWRP, go to Advanced => Sideload => Tick the 2 boxes => Swipe to start sideloading
+ Type in adb sideload <yourzipname>.zip on the cmd (on your computer)
+ Wait for the process to finish, then you now have a working phone...
2 - Follow this guide using the proper firmwares that match your original one : http://forum.xda-developers.com/showthread.php?t=2542219

Your PC will not recognize it as media transfer / storage while you are in bootloader / fastboot mode, its perfectly normal. When you type fastboot devices it should show you a number which means it working as intended. This is an old thread but it shows how to transfer your ROM to sdcard via adb push command. http://forum.xda-developers.com/showthread.php?t=1667929

The output of the "fastboot devices" command clearly shows your phone is recognised by your PC. As I said all you need to do now is use the correct "fastboot flash" commands to restore recovery and system. Tutorials can be found in this forum.

Thank you.
I would like to say thank you to all peoples who help me solving my lost os problem. Thanks for all the informations. My moto G is working perfectly normal right now.

Recover data from my phone that is stuck in boot loop

Hi,'
I think I disabled google app on my nexus 5 (stock android) and since then my phone is stuck in boot loop. (My phone does not go past logo of marshmallow rolls or message saying starting apps 10 of 10). I have very important data that is not yet backed up and I need them to be recovered.
From various threads, I did following in recovery mode
1. Wipe cache option under recovery menu - as it was mentioned, that it would not delete any user data on my sdcard. (No help, still stuck with boot loop)
2. In recovery mode - there was an option to mount phone memory and I did that. My phone shows a message at the bottom of the screen that it is successfully mounted. But I am not familiar how to proceed further or to recover data from my phone.
My phone is running stock android and I think I have not disabled USB debugging. I am not familiar about ADB, but can follow your guidelines and execute them. When I connect my phone to windows laptop, I see my laptop trying to install the MTP device driver, but fails saying unable to find the driver.
I need to recover my data and Any help is greatly appreciated.

Is your bootloader unlocked? I'm guessing not.
Sent from my Nexus 5X using XDA Free mobile app

If the bootloader is unlocked, you could flash twrp and then mount the data partition from twrp. If the bootloader is not unlocked, you could try pulling the data from the phone using adb commands. Was debugging enabled in the rom?

I have not unlocked my boot loader. Is there a guide to use adb with stock android?

Only if you enabled debugging in developer options.

Today, I installed 15sec ADB installer and booted my device in to recovery mode by pressing power and volume keys.
Then under recovery menu there was an option called - Mount / System. I selected it by pressing power key and from ADB ran adb devices.
No devices was listed, when I ran ADB devices.
But I saw another option in my phone recovery screen - Apply update from ADB.
I got a message in phone - "Now send the pacakge you want to apply to the device with adb sideload filename".
Now, when I execute ADB devices in my PC cmd prompt, I see my device with its serial number.
then I tried to use ADB Pull /sdcard/ to recover files from PC command prompt. But I got a message - saying error closed.
Am I doing the right things? Can you guys guide me to recover files from this point.

My bootloader version is HHZ20h. Product - Hammerhead.

I noticed from below link a user has had luck with sideloading a launcher. Has anyone here tried it ? will it affect my data on phone?

Any guide to sideload google search app in recovery mode?

Have you considered side loading the OTA from Google? https://developers.google.com/android/nexus/ota Directions are on the site.
When you get to this point
(But I saw another option in my phone recovery screen - Apply update from ADB.
I got a message in phone - "Now send the package you want to apply to the device with adb sideload filename".), you send the ota zip. (Adb sideload <name of zip> ). You have to make sure the zip file is in the folder with adb files.

I tried to install OTA update and did the reboot. But it did not help.
Can anyone provide me a launcher that I can sideload in recovery mode? Reading from various threads, I think my phone is in this state because I disabled the google app, which is also the launcher.
Thank you

How to perform this flash without wiping my user data? Any guide for it?

Download the stock image from Google that matches the rom currently installed on the phone, extract system.img, boot phone into fastboot mode, and type fastboot flash system system.img at the command prompt, and reboot.

Let me try it. so far I have been able to execute only adb sideload commands, after choosing Apply update from ADB.
Let me try this - fastboot flash system system.img.

Boot ur phone in fastboot mode (From power off to vol down + power), then connect it to the pc and install latest_google_drivers for nexus devices, ull need to manually install them, after that ur fastboot will recognize ur device.
From that type fastboot devices, if u see ur device connected u simply need to get into the commands that the other user gave to you, i u are lucky ur device will boot.
if u had unlocked bootloader the thing was easy as installing twrp 3.0.2.0 and backup all ur data via MTP

Help! Deleted EVERYTHING on ZTE N817

Okay, so when trying to flash CM ROM, I stupidly ended up wiping EVERYTHING in the "wipe" option. Trying to recover it, I tried sideloading the file through ADB, but TWRP would disconnect off the PC and say failed (TWRP version 3.0.2-0). Pushing a ROM zip won't work, as the phone only connects to the PC as ADB Sideload mode ('error: closed' is what it would say), and nothing else would work except sideload. I no longer have a working OTG cable, as my last one broke on me a week ago. The PC will not connect to phone on the 'Mount USB' option from TWRP. Plz help! I'm running out of ideas. I did make a backup (using Online Nandroid Backup, no it wasn't a zip) on the SD card, but TWRP will not read the SD card on my device. Note that the only thing I have is TWRP; no bootloader, no Fastboot, no nothing. Just TWRP.

You can connect to ADB but the adb push command isn't working when you try to move the ROM.zip to the device?
Get a new OTG cable.
The nandroid backup you made should have been done in TWRP and stored on extsdcard instead of the online backup, online backup is crap because it only works in certain conditions, it's useless when the device can't connect to a network.

Yes. ADB commands other than sideload will say 'error:closed', and ADB Sideload will just end up making the phone disconnect. At this point, I may HAVE to end up getting a new OTG Cable.
Yes, I was trying to do the backup on TWRP, but as it couldn't read the SD Card, I used Online Nandroid Backup. Then I realized that everything I was doing was completely stupid while I wiped EVERYTHING....

Yeah, new cable seems to be your only option.

Try rooting the device and then use the Stick Mount app, if your device has the hardware to support OTG, that should enable it, but if your device does not have the hardware to support OTG then it doesn't matter what you do softwarewise or what you modify, it has to have the hardware or it can't do it at all.
Things like this are why I'd never buy or own a ZTE device of any kind. Relatively soeakibg, they are all junk.
I DO NOT PROVIDE HELP IN PM, KEEP IT IN THE THREADS WHERE EVERYONE CAN SHARE

Only thing is, I dont HAVE any system to boot in order to check that. I guess I'm out of luck, no wonder why others said this phone was crap.

If you can use adb shell or fastboot, you can try getting a copy of system.img from someone with your exact device and dd or fastboot flash the img.

Any ADB commands other than Sideload will just respond as error:closed, as the computer only reads the system when in ADB Sideload mode. However, when trying to sideload a ROM, the phone will disconnect and say failed, while the computer stays on xfer: 0.00. Maybe I could get some instructions to fix that? Maybe a bad TWRP version? If so, I'm ****ed...

After reading other pols forums, it seems that I didn't have to delete the internal storage........

Sideloading a ROM won't work.
Try
adb reboot bootloader
If you can boot to bootloader or fastboot you can try finding the firmware for another device that has all of the exact same hardware components that your device has then try fastboot flashing it or extract the separate .imgs from the firmware and use the fastboot commands to flash the boot.img and system.img.

can't get into fastboot, ADB command says error: closed, while doing the command in terminal in the TWRP menu keeps me on ZTE screen (only reboot recovery works, not as ADB command but in terminal).

Did you ever get the TWRP for this? I have it in my dropbox pm me.
The issue were running into is that the TWRP on this model can't see the ext sd. The backup is 1.5 or 2gb which is usually too large to fit on the internal SD
Slacker is working hard at modding the Fstab file to make TWRP see that storage. Any ideas please let him or I know([email protected] or here )
I'm also working on an EquiMods custom ROM for this. Bare bones battery saver, switchable to performance when needed.
Anyone know if and how these can be overclocked?

I have a deodex rom done for this phone and also should have the working twrp recovery by morning. The cm11.0 ive been working on is almost done. I hope Everytime i flash it to phone i get white screen. Also im going to install xposed on it in the morning. I think i found the fix for that to work

Any news on this? I can't find anything that works with this phone. I have adb sideload working, but that's pretty useless from what I understand.

They obviously got something to work since there are members in this thread that have TWRP installed on their devices, that means they can at least root the device but I doubt there are any ROMs for this device.

I've rooted my N817 but never made an Nandroid backup. I still have TWRP up and working but I've tried to flash the 2 roms I know of....they both "install" but when I try to boot It stays in the ZTE screen...Help!
