Can't see in Fastboot Mode the Tablet listed in Fastboot devices. - Samsung Galaxy Tab A series Questions & Answers

Sry, can you help me?
I've got the Samsung Galaxy Tab A 8 (2019) and I wanted to flash TWRP on it.
When It's on System, it's easy to Code: "adb devices", but after "adb reboot bootloader" i can't show it listen in by typing Code "fastboot devices".

That is because Samsung devices don't support fastboot. There are some custom recovery modules that add it, but you need to use Odin or Heimdall to flash from download mode on stock devices.

Can somebody help me to flash twrp with this guide?
TWRP - ROOT - WETAmod for SM-T295 (Tab A 8.0 2019)[Updated 22 February 2022]
THIS THREAD IS DISCONTINUED - AM GETTING TOO OLD TO CONTINUE WETAmod FOR T295 I see people still trying to patch files to get root. If you flash the TWRP posted by @Talich52, with reboot unchecked you can install Magisk from TWRP. Tested on...

It could be your fastboot isn't the newest. It's been a while but I had the same problem, once you get the correct fastboot files it should work.

I have been putting customs ROMs on Samsung devices for close to ten years. I currently have a T500 and an S6 Lite. The S6 has fastboot but only because of the custom recovery. There might be some of the very latest ones that Samsung included fastboot in order to support GSI, but I haven't seen one. And the SM-T295 isn't one of them

I know, but some Samsung devices have fastboot along with download mode, so saying "no Samsung devices have fastboot" would be wrong. And no, it's also with some A series devices as well, I don't know why, it's very weird as well

I can only go by what I've experienced and don't think it is wrong. Of all of the threads in the Tab A, XDA forums, I've never heard of a single mention of the use of fastboot. ADB, yes, but fastboot, no. If you think that is wrong, link to a thread that says otherwise.
edit: I just googled "Do any Samsung Android devices support fastboot?" and every response I see says NO, except for some of the very latest models. No Tab A devices. BTW, there is a difference between the Galaxy Tab A and the Galaxy Axx models. This thread is for the Tab As. Tab As are tablets/phablets and not plain phones.

Yes, as I said, only some devices (mostly Galaxy Axx and M) have fastboot. Therefore the statement "Samsung devices don't support fastboot" is misinformation.

[Q] Is fastboot possible?

I know fastboot isn't possible on the SG3, but the posts i found give the suggestion that it's not impossible. just not implemented yet. so my questions are:
1: is fastboot possible at all?
2: how hard would it be to implement it?
3: can i expect it to happen sometime?
thanks in advance.

some Samsung devices have fastboot, so it's not just HTC only..
and with fastboot you can do some stuff you can't with other methods, like change the boot splash (default it's the screen that says "GT-I5800 SAMSUNG")..
After some searching, it looks like very few people were able to get into Fastboot/Forced upload mode on Galaxy S. Other than that, only couple of older Samsung phones could do that. You could call your provider support and ask for directions on how to get into fastboot, but I dont think they would share that information.

unlocked bootloader?

That's called "Odin" mode or "Download" mode. No, at the moment and (probably not in the future either) it will not unlock bootloader.
This device is quite different from previous Samsung tablets, as I can't find the key combination nor the adb command to boot it in bootloader mode.
Any devs can shed some light on this issue?

Heimdall should find the device if you the latest drivers installed.
You can root the device from recovery and yes the boot loader here is "unlocked " .

Samsung devices do not have "fastboot" mode.
They have "download" mode. Which you can flash firmwares, kernels, modems and such with Odin and heimdall.
Also Every since the SGS2 the "bootloaders" have not been locked.
thanks to the both of you.
ive installed heimdall 1.3.1 tried both the gui and cli mode no luck finding my device. i dont have a windows machine so no odin for me
is there anything that needs to be done inside honeycomb to unlock something?

Why no Odin for you? I have Odin on my Win 7 64x machine and Odin works fine. Make sure you are using odin 1.85. To my knowledge was the latest release.
Here is it attached so you do not have to search for it. Just unzip and use it Make sure you have drivers installed of course.
thanks for the link but no odin for me because i dont have a windows machine. only osx
Odin/Heimdal download mode is the be all-end all preventer for borkage for Samsung phones/devices. (I've had a Captivate & Infuse)
Heimdal should only show recognition when trying to flash something. Hmm. May need to look into other things if it doesn't work. :/

I believe only some of the original 7" Tabs had truly locked bootloaders.
The closest newer devices have is the "custom binary counter" - It trips a flag/warning if you flash something unsigned, but does not prevent it from executing.
Note that some newer Samsung devices changed the download mode protocol and broke Heimdall, although it seems to more typically be "non-Hummingbird/Exynos devices" that have issues. Heimdall won't talk to anything Tegra or Snapdragon based, but will talk to the new Tab 7 Plus. Don't know about the 7.7.
Note that some newer devices are "middle" cases where Heimdall will sort-of work but won't actually flash anything - the Galaxy Player 5.0 (and maybe 4.0 too?) are examples of this.
i havent been able to get heimdall to recognize the device... but i may be doing something silly as ive never used odin before.
I have flashed my 7.7 with odin 1.85 already and it has worked... just a heads up..

You have to be in download mode - if it still doesn't recognize the device in cases where Odin works, I guess that the 7.7 uses one of the newer protocols.

Actually this is not correct. The original 7" Tab was never in the wild with locked bootloaders. Only some leaked test firmwares had locked bootloaders - that is what all the fuss was about back then, because once you had them installed, flashing a newer or older official firmware did not remove the lock. There has never been a P1000 firmware on device in-store or an official KIES upgrade with locked bootloaders. All official firmwares have completely unlocked bootloaders.
The 8.9" and 10.1" Tab family do have unlockable bootloaders, most of them unlockable with fastboot, but on the 10.1v specifically that is only possible with some bootloader versions. There is firmware update to unlockable bootloaders, but still the device comes locked by default.
Interestingly, the Samsung-built Nexus family has an unlockable bootloader, but any use of Odin automatically unlocks the bootloader (same as fastboot oem unlock would). This is something the 8.9" and 10.1" Tab family does not do, you need to unlock first (if I'm not mistaken).
The 7.7" is based on the SGS2/SGNote family of device, which is a completely different heritage from the 8.9 and 10.1 family. The other Exynos based devices are completely unlocked out of the box - I assume the same is true for the 7.7 ?
(Note the subtle differences in this comment between: (a) locked bootloader (b) unlockable bootloader and (c) unlocked bootloader)
OK, I had my history wrong on the original Tabs.
I haven't seen any way to unlock the 10.1 once you got SBK-locked - but the SBK lock only affects flashing with nvflash. So maybe that would be a "locked flasher?" I have never seen the 10.1 perform any enforcement of code signing when booting stuff that has already been flashed.

Exactly that is what has happened to my 10.1v, it seems, just yesterday as luck would have it.

Maybe - as I understand it the v is quite different from the stock 10.1.
The 10.1 non-v has its own set of annoying variants though - Wifi, 3G, Verizon LTE, and one other one. Plus the Google I/O versions had some slight differences from the Wifi (I think they have a slightly different .pit, which is why fastboot can't easily be flashed on non-I/O wifi units.)
For the non-v - You can get SBK-locked if you're not careful. What's annoying is that SBK-locking actually makes Samsung MORE likely to have to offer warranty service - if a device isn't SBK-locked, it's completely unbrickable, as nvflash capability is built into the CPU itself (Just like GalaxyS phones with Unbrickable Mod, and the 5 inch Galaxy Player/Galaxy S Wifi units). If it's SBK-locked - well, if you corrupt the bootloaders and disable Odin mode you're toast, since nvflash won't work. Somewhere around 50% of the initial 10.1 wifi units shipped without SBK locks, but all of them shipped locked eventually and then if you weren't careful, various OTA updates would burn the eFuses for SBK locking if they weren't already burned.

Xiaomi Redmi Note 5.5 2Gb ram 2014 dual sim 3 G. Bricked with no excuse: xposed

It happened long ago in a foggy noon....leaving xiaomi, uncle tools. Miui to an hour of persistence.
Never mastered any Chinese phone. Visited Xiaomi foruns but never solve the brick. Today tried a method involving a "fastboot flash recovery recovery.img" wich should allow twrp img to unbrick by installing a file uninstalling any remains of xposed framework. and recovering. Pdanet involved could not conect with one end...:crying: Last but not the least, it was a solution directed towards a redmi 1 S, not a redmi Note. When decided to photograph for parts, it appeared a menu at the top. Stock recovery? Miui? Sorry for the inconvenience. Xiaomi are great devices. Any suggestions, a qualified opinion, is there a path to recover functionality, considering the level of complexity...
Thank you. Compliments and sorry for the inconvenience
The photo is a typical MTK chipset Engineering mode, nothing useful for you there.
Follow the instructions in the following page: http://en.miui.com/thread-64425-1-1.html
Except download the latest fastboot rom for your device from here: http://en.miui.com/thread-262691-1-1.html
http://en.miui.com/thread-64425-1-1.htmlhttp://en.miui.com/thread-262691-1-1.html Both should answer the question, and I believe they did, Flashtool scattered the FastbootRom and all, except the driver question, went well. Using the tool developed at xda foruns, connecting the phone, one item remained_usb debugging. And that, considering the existence of a flashtool for Linux, is another tour. http://en.miui.com/thread-262691-1-1.html The fact of legacy drivers in Windows 10 were not certified, lead to another path...Options it must exist for a device that turns on, just? does not boot...

Blade A3 Prime (Visible)

Doing anything listed here will void your warranty. I don't know the laws where you are so assume it makes you a criminal. These things are posted here for educational purposes only. Never follow any guide if you don't understand the commands.
Enough BS, let's jump in.
For windows users. Installing drivers:
1. Plug USB cable into PC.
2. On the A3 prime, instead of using USB as charging, select use USB as Updating Firmware (i forget actual wording)
3. A prompt will come up on Windows, install those drivers.
4. Reboot.
Install adb and fastboot on your PC, it is up to you to do this.
Enable developer options on your phone, and enable USB debugging and OEM Unlocking.
In your CMD/Shell/Whatever you have.
adb reboot bootloader
fastboot flashing unlock (use volume up to confirm)
fastboot flashing unlock_critical (use volume up to confirm)
Congrats you've unlocked the bootloader.
Use 'fastboot reboot' to reboot if you haven't done so already.
-----
this is where the progress on this device comes to a halt.
The kernel source is available from opensource.ztedevices.com
The device codename is Z5157V, the Kernel they have is listed under Z5157V Q(10) Kernel(4.4.185)
What needs to happen next? Someone needs to compile the kernel from source.
Once that is done, they can extract the boot.img from it, use Magisk, and make a modified boot.img
Whoila, they will now have root. Once this person has root, they can extract recovery.img from the device, and we can begin making a custom TWRP, or who knows, maybe Team Win will pick it up (unlikely).
Once we have a custom recovery and working Magisk, it's just a matter of time before we start seeing custom ROMS.
If someone will sign up to be a guinea pig, or has an extra A3 Prime laying around I will continue development. I bricked mine because I was impulsive and honestly, kinda stupid. (browse through thread to see my idiocy)
Until such a time that I come to possess another A3 Prime OR someone steps up to provide a firmware dump, I am unable to help.
Good luck developing!
Only managed to unlock the bootloader but can't seem to find any information on rooting it.
The structure is indeed different than what you would normally expect to find. 'recovery' isn't a valid partition when trying to flash under fastboot for example.
The only reason I'm interested in trying to root this device is because The mtk engineering mode app doesn't work on this phone, at least not the visible version, so band locking doesn't seem possible without root and a different rom.
Yeah, I bricked my device by flashing a universal MTK TWRP.
Came here to say this, do not flash universal MTK.
It is a soft brick, bootloops with no access to stock or TWRP recovery.
The phone's model number is Z5157V and the stock firmware is Z5157VV1.0.0B17 for google indexing reasons. Only place that MAY have it is behind a $40 pay wall.
Managed to get the kernel from opensource.ztedevices.com, just beginning to work on it now (not sure how I'm gonna get my phone out of bootloop mode, but I'll solve it later)
I have never compiled a kernel from source, but I'm eager to learn, I have two days in the wilderness planned ahead of me. If anyone would compile the kernel, that is great. If not? I'll get it done when I get back.
Been playing around with the phone and key combinations, I think I have found a way to use SP Flash Tool in it's current soft brick state.
If I am successful in compiling the kernel, I will share it.
If I am able to unbrick this phone, I will write a guide.
If those two things happen, I'll be moving forward to make an AOSP based custom ROM for this phone. Maybe a first for a $100 device, but I like root.
If anyone else knows HOW to compile the kernel, you'd put me a few steps ahead when I get back.
Either way, nearly 200 lurkers on this thread, I hope to have answers soon.

dude, in order to avoid fuqqing confusion you ought not abbreviate a shell command like you do.
Anyhow, since we two guys have different phones, it makes sense only for me to generally discuss the rooting strategy on a ZTE Spreadtrum phone, as the specifics will differ too much.

Sorry, for clarity if on Linux type su and your root password, or use sudo to escalate your permissions if you don't have permission to use fastboot as a regular user.
If you're on windows, consider a free upgrade, but also leave out sudo and once in fastboot mode on a3 prime, type
1. (sudo) fastboot flashing unlock
2. (sudo) fastboot flashing unlock_critical
Press volume up when prompted and congrats your warranty is now void, bootloader unlocked. I'm not responsible for your choices.

this "orange state unlock bootloader" has - however - nothing or little to do with "Developer Menu option UNLOCK BOOTLOADER"
do you know more about this?
on my Lumigon these 2 unlockings are independent of each other, never mind the identical name "unlock bootloader".

Keep checking for updates, once I'm back in town that's exactly what I'll be working on.
Sorry to anyone following this thread, I will continue working on building the kernel, extracting boot, and getting this phone rooted. I will need a volunteer to test the root solution once it is built, and then if possible follow a few steps and extract recovery.img on your newly rooted device and send that to me.
I just don't have the time today even though I said I would be doing it. If there are any volunteers with an A3 prime let me know!

SM-P613. Error vbmeta image.

Hello!
I was recently gifted a Samsung Galaxy Tab S6 SM-P13. I only use my tablet to watch chess videos on Youtube, so I was happy to get a tablet to mess around a bit with it. I did not know much about rooting, but I thought installing Lineage OS and learning from it would be exciting.
I'm good at following instructions, but with some overenthusiasm, I realized that Lineage OS did not support my model a bit too late. So I reached step 5 of "Installing a custom recovery using heimdall" in the official instructions (https://wiki.lineageos.org/devices/gta4xlwifi/install).
But I could not do step 6 as it could not boot into recovery mode. It will stay in download mode with the following message:
<!>
_partition recovery
Reason recovery: Error verifying vbmeta image: invalid vbmeta header(6)
CUSTOM recovery
VBMETA P613XXU1AVG5, 54410278R
I have looked around to see fixes, but I have felt slightly overwhelmed. So I have installed Odin, and at this moment, as Lineage OS is not an option, I don't care which ROM to install (stock, lite, etc...).
Can someone guide me on what to do now so I won't worsen things?
Thank you for your help in advance!

Hi. Liked I said, I feel a bit overwhelmed and risk-averse at the moment. I have Odin installed and a the stock lite version downloaded. Was hoping for a "Try Odin with stock first" before making any further mistakes.

I don't fully understand whether or not you are wanting to return it to normal or not here, but I do know about the S6 lite. I have my own S6 lite, and I noticed no one has been updating the patched files for it. A recent update forces it to have the file it was talking about, and unless someone makes a specific twrp for that device specifically, we won't be able to use a custom recovery to flash a rom.
If your issue is getting it into recovery mode however, you aren't alone. The Samsung tablet's usually have the same method for launching, but this one specifically was weird.
You have to:
1.Unplug it
2.Hold power and volume down
3. As soon as it turns off plug it back in and begin holding the recovery key buttons
4.If it isn't in recovery you may have just missed the small window you had to do it, which is fine just start from step one until it works.
If you did flash your own recovery and expected it to show the stock Samsung recovery menu, that won't happen since you overwrote it by flashing a recovery. You should be able to find your device model on https://sfirmware.com/
In odin "AP" is where you flash your recovery files. If the device isn't working you may have to also flash the "BL" or binaries for your device. I usually do anyway just to make sure it is going to work correctly. Make sure you have adb, and any Android drivers needed for it to work. Let me know if you need more help! Thanks.

Perfect!!! Thanks a lot. I didn't have much expectation apart from "not bricking it". I just wanted to make sure I did not do anything stupid. Follow your instructions. And it worked perfectly! Thanks a lot for the help! I truly appreciated. I am usually alright at a lot of these things, but I ended up being a bit lost, and just wanted to make sure I stopped doing stupid stuff!
Million thanks!!!!
I am facing a similar issue, but I can't seem to find a recovery image, so can you please help with that? I went to the sfirmware website, but can't locate the recovery image for sm-p613, though I did find it for other models such as p610. At this point, I'm fine with going stock os if it means I haven't bricked the tablet.

I softbricked mine with Snapdragon last night. See the fix and link to a working recovery image here. Developer says there's no hope for Snapdragon support for the S6 Lite Wifi now or in the future. Samsung doesn't even support the firmware reload for this device in their own Smart Switch Windows app.
