[Q] Soft bricked after CWM installation / SOLVED

Hi all,
I have a TF300T with stock 4.2.1 android.
As i also own a nexus 7 with cyanogenmod, i decided to also give it a try on my TF300T
Unfortunately it ended in a endless loop of CWM recovery :crying:
This is what i did :
- i started with this thread http://forum.xda-developers.com/showthread.php?t=2055430
- it reference to another thread that describes how to install CWM recovery - > http://forum.xda-developers.com/showthread.php?t=1668173
I followed all 9 point in the CWM installation guide.
After that i wanted to flash the root zip and recognized that the CWM is not able to mount the sdcard and internal memory.
So i was not able to root the device and also not able to flash any custom rom.
After reading in the forum i was able with "adb reboot fastboot" to boot again into the stock ROM.
- Reading more in the forum i learned that TWRP should have been used . So i tried with fastboot to overwrite the existing recovery , but with no success.
- Reading even more in the forum i saw that there is a way to remove the CWM by restoring the orginal stock ROM with the folloing command.
"fastboot -i 0x0B05 flash staging blob" with blob coming from TW_epad-user-10.6.2.6.zip from asus web page.
After that i can not even reboot to the stock android ROM.
I still have CWM after booting of the device.
I can still open adb shell. But su is not working as i do not have root.
What is the best way now to get back to a working android on my TF300T?
Many thanks in advance for any good hints.
/BR

Is that the firmware that was already on it? I'd try installing 10.6.1.15.3 which is the newest firmware via fastboot. Should erase the recovery. I wouldn't do the 27.3 firmware, not all ROMs support it

as i do not have fastboot anymore , how to flash the stock ROM?
Can this be done with adb?
Or is there a way to get fastboot again?
I currently have endloess boot loop into CWM.
And as i can not access in CWM the sdcard and internal memory i am not able to flash anything.
I just saw this thread here - > http://forum.xda-developers.com/showthread.php?t=2236885
They had similar problems and also no fastboot
Other point is , do i need root access to fix it?
Even with adb i can not push files as the partitions are not mounted.
What about using sideload feature in CWM? will this allow to send a custom rom zip?

I finally got back my fast boot.
I made an hard reset (with hole below sdcard)
After that I could start the tablet with volume down and got back to fastboot
By that I am now able to start again the stock android that was already installed. So as long as I do not shutdown the tablet I at least can use it.
I see quiet a lot of discussions in the forum about soft brick tf300 after 4.2.1 ubdates.
I will now follow these and see if there will be a proper solution for my issue.
Thx

Good to get you back to flashing happy. Not sure if it works with the 10.6.1.27. update though.

Finally have reached my goal...

Asus TF300T issues with CWM 6.0.2.3
I bought an Asus TF300T for Christmas 2014. It had JellyBean 4.2.1 on it.
I decided to try to update the device to Lollipop CM12 and admittantly I am a noob when it comes to Android tablets.
So, I installed the ClockworkMod (which installed correctly), but it has my tablet stuck in a loop. It won't mount the /sdcard
and when I open a Command Prompt with Administrator Privileges and attach the usb cable to the device, it won't find it.
I've downloaded the stock rom from Asus for the device and placed it on a 2 GB MicroSD Card that the device will not find or see.
After reading through this thread, I am feeling a bit out of my league on how to recover the device.
Any assistance would be greatly appreciated.

[Q] ADB, Fastboot, and Mount

Hello Comunity,
i would like to install costum Rom on TF300. So i do unlocked my device, put TWRP on it, got a rom on it. I flashed the rom and everything seems to be allright. After Installation my device stuck on the ASUS Logo. So I decid to do another Wipe...
Now i do a bad Mistake. I Format all Data on Tablet. After reboot the tablet it stucks on ASUS logo again. I ll start TWRP and want to install the rom again....and it is erased.
I look the whole forum for solutions and want to push the rom via adb from pc to tablet. but if i do this i get "no device" failure.
So i look to TWRP what i can eventuelly do and there it is: sdcard is not mounted. and i dont get it mounted.
so my question is: what can i do now?
for all who are interested
-i came from JB 4.2.1 Stock Rom
-i ve unlocked with asus app
-i use this blob for twrp: openrecovery-twrp-2.5.0.0-tf300t-4.2.blob (got twrp v 2.5.0.0 on tab)
-i do wipe all data
the rom i wanna flash is CROMi Xenogenesis.
So i would be very thankfull when somebody has an idea, how to get the rom from pc to my tablet.
Greetings and thanks
Cirdan
*EDIT: Thread can be deletet. Has solved the Problem. I ve startet the sideload option in TWRP and Sideload the ROM via ADB.*

[Q] asus transformer tf700 wont start up

please help it says it has no os installed when i go to recovery mode is there a way i can install it with an sd card? where can i download it from please help

Friend - how are we supposed to help if you give us NO information????
How did you get yourself into this pickle?
I used the coffee grounds from my afternoon latte to guess this:
You have a custom recovery installed and can boot into it - which one?
You wiped from recovery and included your system partition. Not a good idea if you're not prepared to flash the rom right afterwards....
You ran some custom rom - which one?
What bootloader do you have installed?
Fastboot access working or ADB in recovery?
If you're really lucky all you have to do is copy your favorite custom rom on a fat32 formatted microSD, stick it in the tablet, boot to recovery and flash the rom.
That is if you have the correct bootloader and recovery installed, but how would I know?

[Completed] Help with reinstalling bootloader

Hi.
I am relatively experienced user who has rooted and installed custom roms on samsung galaxy and HTC desire phones before.
I have now attempted to root my alcatel onetouch pixi 4 (4034X) using instructions from this thread :- https://forum.xda-developers.com/android/general/alcatel-one-touch-pixi-4-t3376597
I got as far as flashing twrp recovery and now the phone is stuck in constant reboot. I downloaded alcatels mobile upgrade tool in hopes of reflashing the stock rom but it seems to be looking for a later rom than the one I have installed and keeps telling me I have the lastest and so wont flash.
So can I recover from this at all or have I just bricked my phone? Is there a way to FORCE the mobile upgrade tool to reflash the current rom rather than looking for an upgrade?
It seems that everything except the bootloader is intact so is there another tool I can use to restore the bootloader?
Any help would be greatly appreciated.

Looks like I managed to unbrick using a combination of SP Flash tool and an SPFT rom for the 4034X I found on the internet. will now try reflashing a different recovery tool.

O.K. so I think what is happening is an issue when unlocking the bootloader and not when flashing recovery.
This is what I did:-
1. Enabled developer mode.
2. Turned on usb debugging and unlocked bootloader oem
3. Rebooted phone, plugged in cable and accepted connection authorisation.
4. From windows typed adb reboot bootloader. Went into to fastboot.
5. Typed fastboot oem unlock, Pressed volume up on phone.
At this point I was put back in fastboot but none of the buttons worked and the phone looked like it had frozen. Was It wiping data at this point? There was no indication that it was doing anything.
I removed the battery and reinserted but when I restarted I got the same boot loop problem. Had to restore stock firmware AGAIN.
Am I doing something wrong?

Update: I managed to install caliv touch recovery without unlocking the bootloader by using the same sp flash tool I used to restore the stock rom. However, I cant install root. The recovery will only let me sideload and I could only find the chainfire SU binaries for sideload (SuperSU 2.78-SR1 and superSU 2.46). Both of these seem to flash ok using adb sideload with ctr recovery but the phone hangs at the boot logo. I also had superuser-r197 (ph's sueruser) but that wouldn't sideload.
So I now have a custom recovery but still can't root
Has anyone succesfully rooted the 4034X (UK)? If so, how?

Hi & welcome to xda-assist,
you can try to force the installation of supersu systemless by this step, chances are good that this will make it boot properly.
boot into twrp >go to the terminal > and type:
echo SYSTEMLESS=false>>/data/.supersu
Don't know if the recovery you use has this terminal option but it's very likely.
You can do additional a Google search on "force SuperSU systemless" to get more information / background information..
Good luck

Thanks for your reply Sam.
I only read that after I had found a copy of a CM13 Rom that worked with The 4034X. I basically flashed superSU first then did a wipe, then installed the custom rom and google apps nano before downloading the supersu apk from google play and reinstalling. Now I have a rooted phone with a custom rom and am somewhat happier. The reason I wanted to root was to remove the bloatware that was taking up 1.5 GB of my already measly 2GB internal memory and this new ROM only takes up .5 GB.
I still have some pain. For example many of the Rom Toolbox Pro functions don't work and I think its because the system image seems protected and refuses to mount rw no matter what I do. Even issuing a remount command using the device name from cat /proc/mounts tells me the block device is read only. I also seem to be unable to verify if I have busybox or install it due to the same reason.
It also took me some time to work out that the boot animations weren't stored in /data/local or /system/media but to /data/system/theme.
This used to be so much easier in the days of ice cream sandwich and lollipop. Ah well!

Update:- Managed to flash busybox 1.26 using a flashable zip via adb sideload in Caliv Recovery (Caliv can't see my adopted storage for some reason).
I'm happy now! Would still like to have a rw system so I can remove some system apps I don't use but its no biggie.

[Q] Kind of bricked tablet but works oO : no gapps and restricted by Family Link

Hi,
[first post here]
I just flashed Omnirom 7.1 on a Nexus 10 because it was lagging with Omnirom 6.1 using the TWRP recovery that was present.
[NOTE : I don't think the ROM or the tablet are relevant to my issues]
I made a mistake and tried to flash the nano gapps (instead of pico) and it failed. I thought I'll do that later, wiped cache and rebooted.
It rebooted OK. The system works much better.
Unfortunately, the tablet is supervised by Family Link (and I did not allow my son to get into developper mode).
Now are the issues...
I'm no longer root (as I can not enter any parental code) and I can not enter developer mode (forbidden by Family link), so no USB debugging.
Family Link app crashes (I guess because of gapps is not installed properly).
Recovery got dead in the process (no more TWRP recovery or any recovery).
Bootloader is 'waiting for download' only (download what ?).
I have the official TWRP app and sometimes I can run it without crash but as the user is not root (the system is rooted, though) it seems like a dead end.
I have a Termux app but, again, it does not run as root so I can not edit the system file that would enable me to flash a new recovery...
I tried to activate adb over TCIP on the tablet but it needs 'UDB debugging enabled' oO.
I understand that I made a few mistakes (gapps, not allowing to enter developper mode in Family Link,...)...
If someone has an idea to allow me to flash anything (ROM, TWRP, gapps,...), I'd be quite grateful... as I feel I now have a soft brick...
Thanks,
Z

have you tried flashing a custom rom or a stock rom trough odin?

Thanks for taking the time to answer.
Since my post, I've read that, in bootloader mode, the device does not need to be 'USB debugging enabled' (that's a relief).
With the device in bootloader mode ('Downloading' and no choice other than 'start'), I'm now trying various tools (adb/fastboot/Nexus Root Toolkit, but not Odin yet) to flash something and I suspect that I don't have the correct USB drivers for it. My PC does detect the USB device but the flashing tools don't (yet).
At least, I now have a lead I can follow...
Thanks for your help and sugestion.
I'll report back when I get something interesting...

Hi Again,
I managed to flash TWRP via Odin... Pretty straightforward tool (despite a cryptic interface)... Thanks a lot for suggesting it.
I was then able to get into TWRP (from the boatloader, that proposes other options than just 'start')...
I then flashed the gapps. The tablet rebooted during the flashing (?)...
I'll have another try... There's hope !
Thanks again !

Hi,
I retried flashing gapps thru TWRP and it now works...
Thanks
