[Q] TF 700 only boots into TWRP - please advise this NOOB!

Greetings -
I have an unlocked TF700 (twrp v 2.5.0.0) and I was running cromi-x. it began to crash a lot so i tried to flash a new rom and i must've done something wrong because now the tablet will not boot up. I can get into twrp and perform the options listed (install, backup, restore, wipe, mount, settings, advanced, reboot) but nothing seems to help. I haven't played with this in probably 6 months so i'm not sure where to start. Navigating these forums is like reading latin to me. I'm sure there is an explanation for this but I can't find it. Can some one link me to an existing thread if this has been discusses previously or help me out? I can't seem to get anything working on this and it's driving me crazy. I know I need to provide extra information to help identify this issue but i'm not sure what that info that is. Any help would be appreciated!
Also, I've tried a factory reset from twrp as well and it gives me the following messages
E:unable to mount '/external_sdcard
Updating partition details...
E:Mount: Unable to find partition, for path '/'
When I reboot following this, it takes me directly to TWRP.
I'm guessing my tablet can't find my SD card? Maybe that's an easy fix?
Thanks everyone for looking at this and thanks for anyone that takes some time to educate me.

Most if all: Do not do anything desperate anymore. Your tablet is savable at this point but close to being bricked! Wait for help, I have to go to work now, but will be back tonight.
In the meantime write up a list of things you did as good as you can remember, find your bootloader version and post that.

Thank you for the reply. My bootloader is "<1.00 e> released by 10.6.1.14.8-20130514"
It also says "key driver not found" immediately before the bootloader data upon turn on

Ok, good start. Now - what's you situation exactly? Can you boot into the bootloader or is recovery the only thing accessible right now?

I can enter the bootloader (hold power on and volume down correct?) and it displays RCK, android and wipe data options. It only takes me to recovery tho.

Please try to be very specific. When you enter the bootloader, does it stay there or does it automatically, without your interaction, boot into TWRP?
Did you use the Wipe Data option from the bootloader or do a Factory Reset from the Settings menu?
Do you have fastboot setup on your PC?
If not, find the instructions to setup fastboot here: http://forum.xda-developers.com/showthread.php?t=2688891
You will need it.

When i enter the bootloader, it stays on the screen. If i reboot without entering the bootloader, it goes directly into TWRP. I am not sure if i used the wipe data option or the factory reset (it has been probably 6 months). I will install fastboot on my PC now.

Interesting.
I assume you do not have any data on the tablet you need to preserve, right?
Once you got fastboot setup and "fastboot devices" returns the serial number we'll clear your misc partition (just in case) and fastboot erase your data partition. I think after that you should be able to boot the rom.
Actually, remind me, what was the last thing you flashed? Did you update TWRP already or are you still on 2.5.0?

Correct, i don't need any data on this tablet; i can wipe it clean. I think the last thing i flashed was Cromi-X (not sure the number; was back in August probably. My TWRP is 2.5.0.0; i haven't updated that one. I will try to do the fast stuff tomorrow morning; too late tonight. Thanks for all your help.

Cool. I need to sleep too
Yeah we're going to have to update your TWRP version. 2.5.0 is too old to flash anything recent. And while we're at it we'll update your bootloader too. All in good time. See ya tomorrow

Ok, here's my thinking:
I don't know why the tablet reboots to recovery if you try to boot Android - never seen that before.
That it refuses to boot the rom - seen that plenty
That it only boots to recovery and not even to the bootloader - seen that quite a few times if the user used Wipe Data or factory reset from settings.
You seem to a have a mix of both which makes it unique.
So my advice is:
to clear the misc partition (where a "format data" request may still be lurking) in fastboot
wipe the data partition in fastboot - just general housekeeping
flash a new bootloader and recovery using your current recovery
Use the new recovery to flash the rom of your choice - which one do you have in mind?
So let's start. First make sure you have a fastboot connection:
Code:
fastboot devices
Then erase misc and user data
Code:
fastboot erase misc
fastboot erase userdata
You are still in the bootloader menu, push the Vol Up button on the flashing RCK to enter recovery
Flash the 10.6.1.14.10 bootloader, packaged with TWRP 2.8.4.0 from this post (2nd zip from the bottom)
http://forum.xda-developers.com/showpost.php?p=55238386&postcount=3
You have to reboot after this step for the bootloader and recovery to install.
You'll see a brief blue progress bar, then the tablet will reboot again. At this point hold Vol Down to enter the bootloader and then enter recovery which should be 2.8.4.0 at this point.
Flash the rom
Good luck!

I have successfully completed the steps preceeding the above suggestions; I am not sure how to flash the bootloader. I am trying to follow the guide posted here (http://forum.xda-developers.com/showthread.php?t=2688891) by using the command code
fastboot -i 0x0B05 flash recovery twrp.blob
however, i cannot rename my blob file (contained in the 10.6.1.14.10 bootloader "second zip from the bottom" that you linked me to) to twrp.blob. it is simply called blob. am I doing this wrong? i tried using the above command with just blob and it didn't do anything.
on another thread (http://forum.xda-developers.com/showthread.php?t=2688891) you recommend visiting (http://techerrata.com/browse/twrp2/tf700t) and downloading the latest version of twrp. Should I download this file (openrecovery-twrp-2.8.5.0-tf700t.blob) and rename this to twrp.blob?
Also I am not sure on a new custom rom; i've been out of the game for a while; any suggestions?

No the zip is a flashable package. You install just like a rom zip:
Choose Install in TWRP, navigate to the zip, check the box for signature verification and swipe the button.
This will write the bootloader and recovery to the staging partition. When you reboot the bootloader writes them to their proper partitions, then it reboots the tablet again. That's when you can "catch" the boot process to go straight back into recovery and flash the rom.
Maybe you want to try CROMI-X first. Still a very good rom and very stable. Or check the dev section, many to choose from...

Unbrickable tf300t

Hello everyone. I am new around here and totally new with android devices. I got my tf300t, installed twrp and flashed to the newest android version. Then my dad suddendly pressed something like restore to the manufactory setting and after that it rebooted and just keep booting with teamwin logo. I can not access twrp recovery mod, it is just in boot loop. I managed to get adb to work, but no fastboot since it does not boot into recovery mode. When I am in adb I can browse the device but the adb reboot bootloader does not work at all. It just hangs there. I can not power off the device because it does not let me, I can not boot into recovery mode with powerbutton and volume down button. After a long power button press it only reboots. I even tried with hard reset button but still the same. Could You please help me somehow? I really need that device for school and I would like to get back into the stock android. Thank you so much for any help.
//edit : I also forget to mention, when I execute adb deviced it shows:
List of devices attached
0123456789ABCDEF recovery
Also the device is unlocked.

Did you tried: adb reboot recovery ?
Did you tried to flash recovery again?
Be sure to use the right recovery for your bootloader. Did you upgraded bootloader to latest ASUS one? One then you're able to flash current recoveries like TWRP like 2.8.5.0 oder 2.8.7.0.
Edit: Also take a look here -> http://droidmodderx.com/prime/?page_id=74

Hello sir. Thank you for answering. I tried adb reboot recovery and it just hangs to be executed... But the tablet is still flashing the teamwin logo. I have the same bootloop as the guy on youtube called Francis Domingo and video called Samsung s5 stuck at TWRP Recovery boot loop (unfortunately I can not add link here).
//edit: Thank you for the link. It look like I have to use option 1a. Is it safe to use that command and I will not make it even more bricked? Thank you so much
//edit2: Now I just realized how to turn off the device to stop from rebooting. I just long pressed power button and up volume button and after the screen went black I kept holding the up volume button. I didn't work with down volume button or if I stopped holding the up volume button after black screen it rebooted again.
//edit3 : Let's say if I get to the twrp mode with option 1a from the link, what do I have to do next to get back to the stock rom (I think it was something like 4.0.3) ? Thank you

What the guy does in 1a is wiping mmcblk0p3.
Afaik mmcblk0p3 is the staging partition. That would be my guess anyway if you had access to fastboot. Usally when you can't boot into recovery, something is wrong in staging. I got the same problem 2 days ago. In this case you usually wipe staging partition via fastboot.
Since you got no fastboot access, you have to try with adb.
After cleaning the staging partition you can flash any recovery you want back again.
The recovery must be flashed to mmcblk0p4 <- 4!!! is the recovery partition. (but you should wipe mmcblk0p3 (3!!!) before)
So I would say, try what solution 1a suggests.
Edit: You can go back to stock android if you want, but there is no reason for this. My advice would be to unlock and root your device, upgrade to latest boot loader (which is done by upgrading to latest stock rom), then flash TWRP 2.8.5.0 and then a useful ROM on top. I'm using the one from timduru which is very nice. You can find it here: http://forum.xda-developers.com/transformer-tf300t/development/rom-t2932783

Thank you for the answer. Could you please write a step by step to get out of brick and to get the stock version, because the newer one I installed was many times slower. The reason why I would like to have step by step is because I don't wanna mess it even more than it is. Thank you so much.
//the stock rom was much more faster than the one I have installed, I mean... the boot time wad unbelievable slow, same with responses and wifi problem. If there is any other faster rom than stock I would be happy but I don't wanna mess with any bugs or slow boot speed and I can not wait minutes until it boots.

Hm, try the Option 1a from the link.
If done, boot into current recovery. Tell me which version and which recovery do you have.
Top on this we can decide what to do to flash a good ROM.

I had the exact same thing happen to me yesterday. Option #1 worked for me.
I did the steps from option #1 and powered down using the volume up + power. I then tried to boot into TWRP recovery, which only reproduced the same issue.
I redid the option #1 steps, and this time powered down using the power + volume down. I powered back up normally, and it rebooted normally into the ROM.
The tablet now works normally, and I can also boot back into TWRP recovery with no issues.
Thanks for the thread and the link.

Thank you so much Catscratch! After I executed both command from option 1a I can get into the screen, where it shows three options: RCK, Android, Wipe Data
In the top left corner, there is written:
Key driver not found.. Booting OS
Android cardhu-user bootloader <1.00 e> released by "WW_epad-10.6.1.27.5-20130902" A03
Starting Fastboot USB download protocol
The tablet can boot into the last ROM but as I said, I would like to have the faster and less buggy rom than this. When I open the settings and click about button there is written: CyanongenMod: 12.1-20150814-NIGHTLY-tf300t and Android version 5.1.1.
If I start RCK it just brings me back to the loop, but now I have fastboot available as it said above and I can list the fastboot devices on computer, which I couldn't before. Should I just execute this command from the computer "fastboot -i 0x0B05 flash system blob" and then "fastboot reboot" or should I download ROM from asus.com/Tablets/ASUS_Transformer_Pad_TF300T/HelpDesk_Download/ -> OS Android -> Firmware and now I don't know which should I choose: If JP or CN or WW or US or TW (Probably US right?). After that should I execute "fastboot -i 0x0B05 flash recovery firmware.img" and then "fastboot reboot" ? Or which ROM should I download to make it even faster and less buggy than stock ROM? Thank you so much again, You saved my tablet
//After I unzipped downloaded US ROM there is no img file. If I remember right the img file is only recovery to reflash the actual one and then when I start the twrp recovery I will select zip file with rom right?

OK, first of all to continue...I assume you got root access. (I think you should have, because you already got CM installed)
Next. Downloads.
Download: https://twrp.me/devices/asusTF300T.html
Also Download ROM+SuperSU: http://forum.xda-developers.com/transformer-tf300t/development/rom-t2932783
And GApps: http://forum.xda-developers.com/android/software/app-minimal-gapps-gapps-lp-20150107-1-t2997368
Push all files to sdcard with "adp push" or in CM. Like you want.
Flash TWRP. (you can skip this step if you already got TWRP 2.8.5.0 or higher version). You don't need latest one.
fastboot -i 0x0b05 flash recovery twrp.img
fastboot reboot
- or -
adb reboot recovery
Now, go into recovery and wipe everything:
- cache
- dalvik
- system
- data
After that flash ZIPs from sdcard. (use "add more zips" option)
1. ROM
2. Gapps
3. SuperSU
Next: Wipe cache and dalvik again (only these two).
Reboot and wait. First boot can take some minutes.

Thank you so much again. Everything work perfectly The rom looks a lot faster than the older one I had there. No issues yet at all. Just awesome. Thank you so much. Really appreciate your kindness and help. You have a nice day !

Thanks. Have fun with your tf300.

Getting a mistake when I try to flash the recovery via fastboot on my Nexus 4

Hey. I just flashed a stock rom and re-locked the bootloader, in order to unlock it, get twrp, get a custom rom (likely lineage) and root with magisk (it seems better than superSU, no?) without any toolkit, because i want to get some knowledge about android.
I downloaded adb and fastboot, enabled USB debugging, booted my nexus 4 on bootloader mode, and I used 3 commands after opening the command prompt from the folder containing fastboot. I also downloaded the latest img of TWRP for nexus 4 and renamed it "twrp" and put it on the folder.
The 3 commands I used are : "fastboot OEM unlock", "fastboot erase recovery", "fastboot flash recovery twrp.img"
But when the phone tries to boot the recovery, I get this : puu.sh/wWTjC/6cf11a9a32.jpg
and it doesnt work ofc.
Furthermore, I can't boot the ROM, I can only boot the recovery and the bootloader. When I try to boot the Rom, i get the recovery.
can someone help me please?
thanks

Hello,
The problem is that the recovery is unable to mount the /data partition, what you need to do is repair it by the following steps
1.Go to TWRP main screen
2.Press wipe
3.press advanced wipe
4.tick data
5.press repair and change file system
6.press repair
7.wipe the arrow
NOTE: this will format the data partition
now reboot to recovery again and check if the problem is fixed

Hello, the problem is I cant reach the main menu of TWRP, after getting what I screened, my phone reboots on TWRP again, and again...
I also tried the command "fastboot boot twrp.img" and i get the same result.

where did you get the twrp from ?
i would in such case as twrp is having troubles first try to find a working version of it, and it it didn't work i would reflash to stock stock and start from scratch

I got twrp there : dl.twrp.me/mako/
i took the latest version.

Get the cwm recovery for your device, wipe data , then try reflashing the twrp recovery

It's ok, thanks

did that help ? hopefully?

hmm, I thought it did, but i actually get the same problem, and I can't launch neither cwm nor twrp..

Once yo reinstall twrp
Go to wipe the format data to remove encryption
You can also use cwm to flash the ROM

Pixel 2 Magisk Bug won't take pin

Pixel 2 XL is soft bricked at the moment and I can't for the life of me think of what I need to do to recover it. I unlocked my bootloader and rooted when I switched to Pie, (I saw people we're already able to use Android pay on a rooted device again and I just couldn't help myself.) I installed twrp accidentally tried to flash TWRP not realizing I needed to temporary boot it and pushing the zip over erasing the recovery I proceeded to just fastboot it and carry on with the normal procedure with my phone. after getting Magisk installed I had my phone all set up until the next time I turned it on and back off again It said I forgot my PIN which I know I didn't I think this was because a glitch with smartlock I just setup so I go to my recovery and wipe the Dalvik cache, cache, Internal storage, and data and low and behold my phone bootloops never making past the final stage before it gets to the lockscreen. I go to Fastboot screen on my phone and my mac can't list my phone as a device in adb and now I am having issues getting back into recovery which I think might be because I am on the stock kernel my Fastboot screen on my phone says Product Name - Taimen, Variant - MSM USF:SAMSUNG(64gig) DDR:SAMSUNG, Bootloader version - TM220j, Baseband version - g899800253-1805232234, my Serial number, Serure boot - Yes, Device status - Unlocked, Vart console - Disabled, HW version - rev_10
I can't get it to stop bootlooping and just turn off.

Try flashing the stock boot.img with Fastboot. That might get you out of it. Since you did all the wiping I can't say for sure. However, when you were at the point where it wouldn't take your password, that's all that needed to be done. I ran into the same thing. It's a Magisk bug. Magisk gets flashed to the boot partition so flashing the factory boot.img will fix it. TWRP also gets flashed to the boot partition so if you flashed it too, flashing a factory boot image will get rid of that too. ADB won't see the phone while it's in fastboot mode. You need to use "fastboot devices". You can download a factory image if you don't have one and extract the boot.img from it. Put it in the folder your fastboot is in, and then open a command prompt (terminal? I'm not a MAC person) from that folder and type "fastboot flash boot boot.img" (without the quotes). Make sure you use download the factory image that's the same as what you currently have installed on the phone.

I stopped my endless bootloop! Now it says my device is corrupt and cannot be trusted and may not work properly when I tried to start it I couldn't get past the google screen. When I plug it into charge now it doesn't automatically going into a bootloop that can only be stoped by going into the fastboot mode or running out of battery, but the the charging symbol on the screen won't go away. I might have wiped system when I was in TWRP when I couldn't boot back after the first wipe. And I accidentally tried fastbooting Telstra img first. Anyway to get past this white Google screen? Also when I trey to go to recovery now it's the android laying on it's back with a red triangle and it says no command. Should I execute the flash-all script?

Downloaded the stock img files and ran the flash all .sh and now I am back in Android ready to mess something up again I could not thank you enough for your help I am so happy right now

Glad to hear you got it working again. As for the recovery screen that say no command, that't the way it works with the stock recovery. When you see that screen, press and hold power and volume up. That will get you into recovery. If you happen to try rooting again and get stuck in a bootloop or some such thing, just flash the stock boot image.. That should get you going again.

[HELP] bootloop when trying to update rom

Hello, i have tried to update to the latest crdroid "april 23" zip and it has made my phone unbootable. After i have finished flashing rom and recovery flasher, i have not been able to decrypt my phone after the reboot to recovery to try and install gapps and magisk. I've also tried to boot to the rom and it has only showed a black screen, and after that it reboot to recovery. The decryption message has appeared again when i did that and after i decrypted and flashed the other stuff i have not been successful to boot to the rom. I have then once again tried wiping and flashing rom and recovery and reboot to recovery again, and again the decryption promt did not appear. After that i've tried booting to system once again and it appeared and after flasshing the stuff again it still has not booted. I've tried downgrading to the previous version when i wiped instead of the newest one and reboot to recovery again and then it didnt show the prompt. I tried rebooting to system again to get the prompt to decrypt but now it doesn't appear even then. I've also tried using the command "twrp decrypt (my pin)" and it gave me an error. I am now in school and cannot do anything untill i get home but even then my computer monitor has been hit and now doesnt function so i cant even do anything via ADB. I have another computer and monitor and im thinking about using it instead. Can i get a step by step on how i can get my phone to boot once again? Even if i lose all my data im fine with it but i prefer not to since i have alot of pictures that i really wanna keep. All help is appreciated. Now that i cant boot to the rom i cant use telegram on the web either so im completely ****ed. Cheers!

An update .zip is always installed to the inactive slot. Start TWRP and open the reboot menu. Change the slot back to your running system. From there you can try to find the reason why your update fails. You don't need a decrypted TWRP for this.
You can also change the boot slot via fastboot command
