How to Unlock Egypt School Tab A (2016) SM-T585 - Samsung Galaxy Tab A series Questions & Answers

Hi
I Have Tab A (2016) SM-T585, it's a school tablet locked on some specific apps (no play store, no youtube, nothing except school apps)
now the Government cancel this tab and back to old learning way
so i need to use the tab normally
i can't go to download mode, i tried (home+vol down+power) and it restart to system
also, I entered recovery and pressed reboot to bootloader
in all ways, it reboots to system
it seems that the download mode is disabled
so I can't access it to use odin to flash TWRP or even another stock firmware.
the only options I can access
1-recovery mode
2-(Recovery / apply update from ADB), i see it when i connect to pc and type "adb devices", but i don't know what this can do for me
when i enter adb mode and type "adb reboot bootloader", it says "error: closed"
3-(Recovery / apply update from SD card)
Does anyone knows a way to flash TWRP or even a stock rom (from sammobile).
Thanks

How do I unbrick a bricked P9Lite with a locked bootloader and without USB debugging?

Greetings all,
I recently got a P9 Lite but I bricked it trying to install a newer firmware on it (tried to go from 6.0 to 7.0). I've read various unbricking guides over the past two days but to no avail. I'd like to know what my options are at this point and if it is possible to unbrick it and bring it back to a usable state even if on a different rom.
How I got here:
The firmware that came with my phone was L23C605B120. I tried to update it to L23C605B362 and downloaded 2 zips (update.zip and update_data_full_VNS-L23_hw_la.zip). I unzipped update.zip into the dload folder of my sdcard and updated it via the dialer. The update installed and my device rebooted but now to this bootloop state.
What I can do:
If booting up normally, I end up in Huawei's erecovery. I can also boot to recovery mode where I can either "Wipe data/factory reset" or "Wipe cache partition". I can boot to fastboot & rescue mode but it says my phone and frp are locked. When pushing all three buttons I can boot to where the phone will attempt to update with the dload folder in the sd card again.
Stuff I have tried:
In erecovery when I select "download latest version and recovery", I can connect to my wifi but it always fails at "Getting package info failed". In recovery mode the factory reset fails and I don't think wiping the cache partition did anything meaningful. In fastboot & rescue mode it tells me to open HiSuite where there is a recover option but clicking it says "Your device is not supported for system recovery". I can see my device using fastboot on my computer but it seems almost useless here since its useful commands fail with "command not allowed" probably because my bootloader is locked. On my computer I installed the USB drivers adb needs and rebooted but adb cannot see my device presumably because I hadn't enabled USB debugging prior to getting bricked. At this point I'm downloading different roms to my sdcard and trying to flash with the 3 buttons method but pretty much all of them fail at 5% or 7% including the rom with the same version that my phone came with. The only one that doesn't fail at 5% or 7% is the rom I tried to flash that bricked my phone which fails at 99%.
So I cannot flash TWRP because my bootloader is locked, I cannot unlock my bootloader because adb cannot see my device, adb cannot see my device because I probably never enabled USB debugging and I cannot enable USB debugging because I cannot boot to the OS. At this point my only option seems to be trying to flash a working rom with my sdcard but I have yet to find one that works.
Where should I go from here and what are my options at this point? Is there a specific rom I should be looking for? Is there some intermediate downgrade rom I have to flash or is there a way to undo the update I just did? Is there a way to somehow enable USB debugging or to unlock my bootloader without it (perhaps via an exploit)?
Any help would be much appreciated!

T560NU - Weird download mode, boots to recovery automatically

Hello! So I 'm trying to get Lineage on my tab here, and of course you must install TWRP to do so, but after following tutorials and such with ODIN on how to do it, it finally boots back up into stock recovery. I try booting back up into Android but no luck, it just boots back into recovery. I tried going into download mode and flashing again, but it doesn't return with the normal light blue 'Downloading' screen, it shows the initial boot image with text in the corner, similar to normal download mode, says system status / current binary = custom, FRP lock off, etc. I plugged in to ODIN but it doesn't show up, neither when using plain old 'adb devices'. I've had some luck though, i can flash using adb sideload, or from an SD card via recovery mode, but nothing works since they're not signed apparently? Please someone help me if you can, im looking to use this as my daily driver mobile computer, since my laptop has a screen problem. Thanks in advance!

J320V won't enter recovery mode

This is my uncles phone and the wifi stopped working so I figure I'll reboot the phone into recovery and clear the cache. I've tried volume up + home + power and it just boots. I've tried doing this through adb by typing "adb reboot bootloader" and it reboots into odin mode but Odin doesn't see it. I have the latest Samsung drivers installed and plugging the phone in doesn't beep or show any device found. I'm trying to flash factory firmware to fix this but I'm stuck. Can anyone help please?
Never mind, I figured it out. I typed adb reboot download and from there I can use odin.

Download Mode Corrupted

I have a samsung galaxy tab s6 lite and I was going to put TWRP recovery on it but when I gone to download/odin mode it just says "starting fastboot".
Its not the usb drivers or anything because when I do lsusb on my PC it recognized it but not the odin software.
Can someone tell me is there a way to fix it?

Looks like you used 'adb reboot bootloader' for entering download mode?
This works on older samsung devices, but on devices launched with Q samsung has a very limited fastboot in bootloader, so to boot to download mode you have to do 'adb reboot download' instead of bootloader
But keep in mind that if you still need to unlock your bootloader you have to boot to download mode using the method described in TWRP thread (with volume up and down) else the unlock option won't be available

OnePlus5 Data Recovery

Hi,
I'm stuck in a boot loop of my OnePlus 5 (A5000, product name msm8998 - msm UFS) with stock rom. Also stock recovery and bootloader locked, secure boot: yes
Already tried:
- Button combos (Volume up/down while starting, forced restart (vol up+power))
- In Stock Recovery Mode i can sideload. Tried to sideload latest OTA from OP5 website, success, restart, still bootloop (adb devices only shows device in sideload mode)
- Fastboot mode does not list device (adb)
- Tried to wipe cache / reset system settings
The sad thing is that I can see my folders / data if "install from internal storage" is chosen, so I know it's still present.
Any hints?
Is there any possibility to get my data off the phone with OnePlus stock recovery and/or sideload? (adb pull throws "error: closed")
Thank you all for helping!
No ideas? That seems bad news for me as all data will be lost in that case.
Anybody got some hints where you could point me to find additional ways I could try?
