TCL A509DL NO FASTBOOT-ABILITY??

[JansenLove]

Hey there guys and girls. I just bought a cheap TCL A509DL to experiment with and immediately hit a roadblock of megalithic proportions...no fastboot mode available on this cracker-jack prize equivalent phone. Seriously...no way to boot into fastboot mode.
All the usual processes have been eliminated...enabled Developer options, enabled OEM Unlock for Bootloader, enabled Usb debugging, etc...all ready, set, don't go.
I powered off the phone, restarted while holding the power+vol dwn, pwr+vol up, pwr+vol up and down, pwr+assistant key, pwr+vol up+assistant key and every combo thereof including every combon with the battery removed and USB connected while keys pressed. I gotta get to this fastboot or I'll go nuts...PLEASE!! Somebody help!!

Check whether Fastboot is supported or not via ADB

adb devices
adb reboot fastboot
fastboot devices

If a connection with bootloader got successfully established don't forget to end it

fastboot reboot

TCL is never known to have offered BL unlock for any of its device. On top of that, US carriers tend to enforce non-unlockable BL, Straight Talk / Tracfone (implied by the DL suffix) the worst among them.

Hi I have tried all of the above commands and about a dozen more. I'm tempted to believe what
I was recently told, that US Phone maker enforce the no Unlock bootloader policy. There would still need to be some window or method available for flashing in the event of a software failure, right? In the Developers menu it says the bootloader is already unlocked and the toggle is grayed out. When I reboot from ADB using adb reboot fastboot my phone reboots back to startup with no fastboot connection??

I also happened on one of these TCL A3's (A509DL), and I confirm that there is no fastboot mode, and only 3 options in recovery, no adb or sdcard or log access, strictly factory wipe and cache wipe.

Hopefully mtkclient will crack this baby open a little bit, I left my laptop in a friend's truck, but when I get it back here in a few days ill hack the crap out of it!

Hey bro. Thanks for responding. Let me know how it goes. I can't even find Stock Firmware for this little pain. Mine is branded TCL A509DL a friend has the exact device thru Cricket branded Alcatel with a different model number but same deal zero fastboot or bootloader for fastboot. Now I HAVE to crack this pain.

Try with python mtkclient , not responsible, you got to know what you're doing, very easy to brick

I just got a tcl a3 (a509dl), dumping the firmware right now with mtkclient. I had driver problems with Windows (ghostspectre 11).. used the 're_livedvdv3' bootable iso. So far so good

Woo thank you for the info ! Unlocked and magisk rooted. Do we have twrp for this device on xda?

I'll even teamview with somebody and use unlocktool to make the backup.

Following . Still need the stock firmware or dumps

 

[iamx51]

Bahh... lame, I'm still in need of firmware/dump. Bout to go buy another one just to get it. lol .. they did have this phone at dollar general, I think its like 39$ .and the chick that's usually working gave me a discount, so the last one for $20. I think I have myself sufficiently talked into it now. If i do buy another, I will upload it for you guys.

Man, if you get another one I would love a backup from it.

I have succeeded in getting the one I have already to allow me to do another dump, but it only boots to the bootloader says the dm-verity corruption crap, then reboots itself.c

If I remember correctly, this began after flashing a Magisk patched boot.img .. it is possible I did something else, but pretty sure that's what happened. messing with it now, will start the dumps before I pass out

I'm pretty sure that's what screwed mine up too. But mine won't even come on now but I'm still able to connect to the chip to flash.

For clarification, are you stating that you have unlocked the bootloader and rooted the TCL A3 (A509DL) branded by TracFone Wireless. If so, as far as I know, there is a $1,700 cash bounty up for the first person to OEM unlock and/or root the A509DL.
