[SOLVED] Problem with fastboot/recovery with TF300TG

There is some similiar threads about this, but I still haven't found solution to my problem. I also tried to post this same problem on general: (TF300TG)For All Your Jelly Bean discussions-problems, but I thought if this was better on troubleshooting.
I got problem with recovery/fastboot on tf300tg..
Background: I haven't root my tf300tg, I got 4.2.1 (10.6.2.11) and I have unlocked bootloader from Asus support and installed APX drivers to windows 7 which works with tf300tg. (even when it's not so needed?) Also I got USB debugging on.
Problem: When I press (Vol Down + Start) to get in bootloader and try to start RCK it gives me error ("Virhe" means error in finnish).

Second Problem: If I can't use recovery I could try to use fastboot. I downloaded ADB and tried to follow instructions but there is one problem with this. I can use fastboot only when my tf300tg is on normal mode. So I can't use fastboot in recovery or in bootloader mode. I'm not sure if I should use fastboot in normal mode (don't know if it's safe?) to install TWRP 2.6.0 (for tf300tg)
Normal mode:
APX mode/Bootloader mode:
EDIT: After 5 hours of finding, I found that reason was ADB version. Fixing this problem was download: minimal adb and fastboot program to windows.

HELP! Nexus 5 won't boot

Hi, updating my Nexus 5 to marshmellow has left it stuck at the boot animation. I can get into recovery and have flashed factory 5.1.1 and 4.4.4 images but all that changes is the device loops with older boot animations. Kwongger's NEXUS 5 Toolkit v2.2 completed successfully but didn't improve anything. Trying to flash Cyanogenmod I run into adb "unauthorised". The device had usb debugging enabled and the RSA key of the PC was accepted but after multiple factory resets it appears to be gone.
Is there anyone out there with the experience to help me fix my phone? THANKS!!

How did you flash the image!! the google site for factory images isnt giving me all the files just one file once extracted...missing all the flash scripts...and win bat file...i downloaded lmw48b and 48m both the same sceanario....what file did you flash??

Are you grabbing the images from here?
https://developers.google.com/android/nexus/images?hl=en
After unzipping e.g. 6.0.0 (MRA58K) I have the following: (check your AV if you have missing files)

Does no one have any advice for my bootloop issue???

Unbrick LG f70 d315

Good evening at all!
Sorry for the trouble but after long hours of research and attempts without solving the problem I thought to try to ask with a thread.
I'll explain what's my problem: I have a lg f70 d315 that no longer wants to start.
It has not been used for a long time and I can not tell you what was done to it last time.
The phone stays locked in the boot screen with the LG logo.
I tried to perform a factory reset from the stock recovery but the situation is not changed. (it stays stucked on "performing factory rest")
I tried to start the device in download mode pressing Vol UP while booting but instead of showing the download mode screen, the fastboot commands are shown (as in picture)
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The bootloader is locked so I can not flash a modified recovery (which I find here https://forum.xda-developers.com/chef-central/android/recovery-twrp-2-8-7-0-lg-f70-d315-t3278742) or flash the file laf.img necessary to access the download mode.
any attempt I do to flash shows these errors
Even when testing with "fastboot boot recovery.img" commands, the phone loads the TWRP recovery but remains locked in the twrp logo screen, without continuing or allowing other operations.
is the device unrecoverable?
Connecting it to the PC is only recognized when it is in fastboot, in all other cases (with mobile phone off, during startup) is not shown by windows.
Thank you very much for your help or just having read the post,
Enrico

Stuck in bootloop Blu Advance 5.0 HD

So I tried to install TWRP to a Blu Advance 5.0 HD (seems there's not much info on these phones too) and after some bootloops with TWRP (for a failure in the recovery script), I was able to get back into fastboot and flash the stock image from bluroms info website, however now it simply goes to the BLU screen and restarts all the time. I've tried every possible combination with buttons but can't get anywhere, any ideas?
Edit: Upon further searches and realizing I screwed up and flashed boot.img instead of the recovery image from bluroms website, I have also found that I have no way of recovering the device with adb/fastboot, but that I could have a possibility if I use SPFlash tool (Yes, it detects it when plugging it in and whilst it is doing the bootloop) to try and flash the correct file to the device (which currently fails with an error message that doesn't have many details [I do the following things to get the error:
1 - Load the scatter file.
2 - Select recovery to be flashed.
3 - Click download
4 - Plug phone into computer
5 - Wait for download
6 - Error message pops up:

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
]).
If there are any ideas on recovering a device from this state without having to buy anything, it'd be appreciated. (And hopefully a good list of instructions on how to use SPFlash tool to recover the device).

Question Block in boot after fresh install with LMSA

Hi,
I am fairly new to flashing and rooting android devices. I managed to root my tablet a few months ago using the following sc00ter98 procedure:
Pad 11 (TB-J606F) Unlock! Magisk! RoooooT !!!
https://4pda.to/forum/index.php?showtopic=1014576&view=findpost&p=107199725 Translator from Russian: https://www.deepl.com/translator 😁🙃(y)
forum.xda-developers.com
But after that I noticed that my tablet no longer received Android updates, I wanted to manually update Android using the LMSA utility. I made a backup of my data before that so I could afford to lose everything. But once the process was finished my system won't boot anymore. In fact I am stuck on a menu at startup not knowing what to do.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
This is the only menu I have access to. I can change the "START" with volume buttons and there are :
Restart bootloader
Recovery Mode
Power off
Boot to FFBM
Boot to QMMI
But watherver I choose, this only reboot the tablet and then go back to this menu.
I would then very much need your know-how if you please!
Thans by advance,
Jiddu
