hi, first of all, i'd like to tell you i'm quite a noob
i have a tf300tg and i tried to flash the jb 4.2.2 that's only available for the 300t.. i'm dumb, i know.. and now in stead of booting it goes directly to the cwm menu and i can't do anything.. i keep getting the error E:Can't mount /cache/recovery/command , .../log and .../last_log
is there anything i can do or should i just throw it in the trashbin ?

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
Hi together,
I've got a Motorola Photon Q 4g LTE mobile phone and this afternoon I wanted to install CyanogemMod, but whatever I do, I stuck with the following problem:
I can't install any other Custom Recovery. I tried ClockworkMod and OpenRecovery, but I always get the s**t Motorola Bootloader, when I start in Recovery Mode. The Bootloader of my Phone is unlocked via Motorola Website, as told in many other threads.
I know that the users arrrghhh, shabbypenguin and Skrilax_CZ are great experts with firmware and such things, but I'm not allowed to write in developer's forums because I'm new here.
Has anybody got an idea for me, how to geht the Custom Recovery to work?
Btw: I tried to root the phone as well, but that wasn't posible. May be things come together or depend on each other.
Thanks for your help!
When you flash recovery (IE run the fastboot command) is it successful?
With the phone in fastboot/bootloader mode, type "fastboot devices" in the command prompt (where you run the fastboot flash command) and what does it output?
Also, try this.

When I flash recovery, I just flash the Motorola given Recovery by Motoroloa Bootloader. The Phone restarts, a logo with the Android Man is shown (stomach opend with some engeniering tools in it) and after about 5-7 Minuten, the system starts normally.
I also managed it to change the "Unlocked Message" into a Motorola Logo by using fastboot flash logo xxxx.bin and I nearly destroyed the flash by flashing an unlikely file. So the phone was shortly out of order because oder "flash failure" (fastboot mode). After that, I managed to flash the "boot.img" file of an CyanogenMod, so the flash was rebuilt and I could use the phone normally.

It shows the connected devices by showing a 8 or 9 ditigt number. It's almost the same view like I connected the phone without fastboot and use "adb devices".

This one I didn't tried yet, because I was so dissappointed of the mismatch with ClockworkMod & Open Recovery. Do you think, that trying this one will help, after two others failed?!
Thanks for you notice and your time. That's very helpful!
You need to boot to recovery after flashing it. There's a shell script that is re-flashing stock recovery - the dead Android dude with tools sticking out of him is stock recovery....

Ah ja, now I'm one step closer. I did not know, that the dead Android dude is the sign for stock recovery.
I'll give it this afternoon another try and will report. A bunch of thanks to you at this time!
Hi, it's me again. I managed now the reboot to recovery, by holding the volume up button while doing the "fastboot reboot"-command with the command box. That worked and I could start Photon Q Open Recovery 2.06.
Unfortunately, I did something wrong or so and now the script re-flashed stock recovery again. Nevertheless, I now know how to operate and will do the rest by my own (hopefully).
@arrrghhh: Thank you very much for your help!
So, I finally did everyhting the right way (now with ClockworkMod Recovery), because I now have CyanogenMod running on my Motorola Photon Q
:victory:
@arrrghhh: Thank you very very much!
Purchased an Lg Gpad 7 Wifi tablet (v400) 2 weeks ago. Came with preinstalled Lollipop android so i couldnt install a recovery rom to flash any other custom roms. Downgraded to Kitkat version following the instructions on Xda forums and succesfully installed Twrp. When i installed Cyanogenmod 12.1 through Twrp i got stuck in fastboot screen.
Any suggestions and / or solutions would be greatly appreciated.
I had a similar problem.. Only mine was stuck at the bootloader. Go in TWRP and repair /data and other partitions. My data partition gave me an error since F2FS is a little flaky and some ROMs corrupted it (claimed they supported it). I would recommend erasing the system, cache and data partition if you can't get into TWRP.
The problem is i cant get out of fastboot whatever i try. It says start on bootloader but the tablet just restarts on an empty screen doing nothing.

if you have an sd card, try removing that, then reboot.
if that doesnt work, try entering fastboot command, fastboot continue
Tried without sdcard and i get the same fastboot screen.
How can i give any commands? The only options i have are Restart Bootloader / Restart / Power off. Tried restarting bootloader but i get nothing in return tablet just stays on with nothing on screen.

you said it was stuck on fastboot, if thats the case, install any needed drivers on your pc, connect device to it, open a terminal in the fastboot dir (after you go get fastboot), then try those commands i gave. you could also try, fastboot reboot dont think i mentioned that before.

Did as you said but every command i gave gives me an error message in adb terminal. There are new lines in fastboot menu in tablet now. Bottom two are SECURE BOOT - enabled & LOCK STATE - locked.

hmm, ok, im guessing it would have said that normally, when not broken. all the command does is try to release it past where its stuck. it doesnt actually flash, lock, unlock, or change anything.
imo, this seems good, because now we know fastboot is working.
i own lg devices, but not your specific device. i would hate to give you some bad advice and make your tablet broken more, but if it were me in this situation, i would try to flash the factory KK firmware you used to downgrade with odin or however you did it. hopefully, that will clean everything up and let it boot properly.
if for whatever reason you cant do that, we could try extracting the factory file, and just flashing recovery and system, those should be the only things that got changed putting on twrp and cm normally.
Sorry, I have the serious proplem wtih my LG pad V400, I rooted it and using <LG Flash Tool 2014> with <V40010c_00.kdz> to downgrate the firmware but their is error then my LG pad stuck in fastboot menu as with just turn off, restart and restart bootloader. if i seclect one one them the tablet just logged again the fastboot menu
it stuck on the fastboot menu and i cannot do nay think with it. I can restart with factory restore mode but when select yes to restore, it will restart and log in fastboot menu again.
I downloaded adb and fastboot program and put in one folder <Minimal ADB and Fastboot> in C:\Program Files (x86)\Minimal ADB and Fastboot
I dont have recovery image so i download file <cm-13.0-20160421-NIGHTLY-v400-recovery.img> form your link to download TWRP file
move it to folder of fastboot programe and changed its name to <recovery.img>
I turn on the tablet and it waited at fastboot menu
when i run the command <fasboot flash recovery recovery.img> and they said some thing wrong like in picture
please help me
My question is: Is there any way that i can install any custom recovery now, when I am locked out of my phone, so I can try Method 7 from this post . I have enabled USB debugging, but for some reason, my device is unauthorized from executing adb commands.
I have Xiaomi Redmi Note 3, and have forgotten its password. I have tried Method 2, 5 and 6 from this post, but to no avail.
I tried method 2 and 5 which requires ADB to be installed, but I was not able to access my phone. I have USB debugging enabled and my phone is not rooted. When I tried to run the following code:
Code:
adb devices
adb shell
it showed that my phone is unauthorized and error: device unauthorized This adb server's $ADB_VENDOR_KEYS is not set
Here's the screenshot:
When trying method 6, I had to change the path of ADB driver because the file I downloaded from the post, had its own ADB driver which clashed with my already installed ADB driver, but even after that, it again showed the above error. Here' the screenshot:
Finally I want to try method 7 from the above post, which requires custom recovery to be installed on the phone, is there any way now?
Though it seems now that the I have only one option left and that is to factory reset my phone, but if , there is any other way by which I can bypass my lock screen, please please please inform me.
Of course you can. Just boot your phone into fastboot and do "fastboot flash recovery <recovery image name>.IMG" and you'll flash it. And you can't access the adb because your screen is locked... This is how companies prevent phone hacking
So flash custom recovery, backup the /data , factory reset and after resetting restore the /data backup. And you're good to go. I suggest you using TWRP, because I use it and it never left me hanging Keep me updated.

OK... So first boot into fastboot. When you've done that, connect It to your pc with usb, download fastboot package from somewhere on xda(you'll find it).
Open command prompt "CD" to the directory where your fastboot is located in, put recovery image in the folder where fastboot.exe is and type "fastboot flash recovery <recovery file name>.IMG". I'm gonna update this answer in 2 days, when I get to my pc, so try to do it by these instructions, if something isn't working, comment and we'll resolve the problem. If something isn't clear, just ask. Keep me updated.

Can unlocking my bootloader somehow brick my phone?
Everything can brick your phone. Updating my lenovo phone with official update hardbricked mine... But yeah, it can.
hi guys,
i my shield is stuck on the nvidia logo when booting normally, if it brings up the bootloader, it shows unlocked but hitting continue caused it to freeze on the screen, recovery freezes on nvidia logo and fastboot protocol just brings it back to this screen. i orginally installed twrp and it confirmed successful flash of new os .... on reboot it bricked to its now state, i cant get into twrp or get my pc to see it to install a new copy
anyone got any ideas
thanks
@Fairmax don't click continue, it freezes because there is nothing to continue to, as long as you can enter bootloader your device isn't fully bricked. So, to fix your problem you will have to download official ROM from nvidia's site (https://developer.nvidia.com/shield-open-source find your model and click recovery images).
When you download latest ROM unzip it and follow the textual guide, but, there will be one file missing (i can't remember which one, user data maybe or something like that), don't worry and just continue with the next step. After you flash just reboot to system by holding power button. Good luck !
i cant seem to get it to be recognised by windows all i get is this-- Windows has stopped this device because it has reported problems. (Code 43) A request for the USB device descriptor failed.--
trying to install nvidia usb driver via have disk bring up an error that the file is not usable with x64 system

Well of course adb devices shows no devices because you are not actually in adb mode, you are in the bootloader mode. Just download minimal fastboot and adb, install it and extract recovery image into the folder where you installed minimal adb and fastboot (you don't need any other drivers).After you did this and your device is in bootloader and connected, click on the path in your fastboot & adb folder and delete everything and type cmd. No need to do adb devices, just proceed with fastboot flash ...

Hello I had a similar issue with my k1 tablet and ended up flashing factory images via adb fastboot and all flashed fine. Now my tablet is stuck on the boot screen with the green and white nvidia logo. How long does it take to boot please?
I have same issue too. I can load TWRP and flash the other partitions but TWRP shows un-mountable partitions and even a full stock ROM flash will not allow it to boot. I have a similar issue with a recall tablet. what did you do to fix it?
