Alcatel TCL A502DL/A501DL root/custom recovery/custom roms?

[lmgnsa]

Is there any way to get root/custom recovery/custom roms on the A502DL or A501DL? If so, how?

 

[PizzaG]

sweet, i got a few a501dls to test it out once youre ready

not going good, I'm getting secureboot failure and nothing boots but twrp. mtkclient doesn't write vendor or system. Nor dumps system. Confused, bootloader says unlocked, unsure how to proceed

Update: Somehow booting again and got rid of encryption in the process

nice, looks like youre making good progress, was gonna ask if you had flashed an empty vbmeta

there is no vbmeta on this device. if you would like to continue helping me test stuff, please contact me on Telegram since it's live and much quicker to post test stuff and talk easier.

as a side note, to my recollection, there is no dev in this thread doing anything with this device except me, so I fail to see how your quote to rule 5 pertains to this thread. Seems to me this is just a random thread about a random device. What you are essentially doing is cutting off everyone from test releases and general info about this device in favor of forcing people to stay on your site. I get it but I feel that goes against the whole dev community. But that's fine anyways, it is not worth my time to try and fight XDA mods over outdated rules and regulations and sharing my time and energy, I'm scrapping this project... My personal dev routine is to hop on XDA and see what's available for a device, I contact all threads related and drop some info and a link to my TG group. Once I get a tester I usually put out several test releases/bug fixes and then at that point, I will go ahead and make my own xda post for said device with mostly tested releases. I honestly can't be bothered with the slow trickle of info and chat that you find with a forum as my personal time is important to me and I don't have alot of it to sit around waiting for responses and feedback and such. Again, I understand you XDA Mods are trying to keep people on your site but I seriously can't relate and at what point does this not become Bullying?

ya, it has a few fstab issues I need to fix for mounting external sd and usb-otg. I'm working on Custom Stock now that kills encryption and other security to get ready for GSI Roms

Testing Custom Stock Rom now

I built for this one a while back and I think everything works. I will post asap.

I have one that's almost functional, it boots if I 'reboot to bootloader', but I locked up the normal boot process by trying factory reset from settings instead of twrp, so now force boots to recovery.

Does anyone know which file to delete in order to stop the factory reset when invoked from settings menu? I've googled it and can't find anything, but I know there's a file that either needs to be modified or deleted and it will no longer try to boot to recovery/factory-reset

Thanks!

Yes, I had already tried that, to no avail. Also, I flashed the lk image found in the a501dl.zip package, and now I might be bricked pretty hard, but I'll use mtk-tools and see if I can restore the factory lk.img, if anyone has it, or if lk2.img is the same kind of like the old bootloader backup partitions

there is an lk2 you can backup and restore to your lk partition

Like most TracFone branded mobile devices, this TCL A3 variant is not supported for bootloader unlocking. To date, no exploit has been discovered to circumvent the perma-locked bootloader. Therefore, root is not possible, since Magisk systemless root would require flashing the /boot partition with a Magisk patched boot image. With the bootloader locked, the /boot partition is fully.write protected.

 

[PizzaG]

Fastboot is crippled on these devices so please, everyone stop talking about fastboot. Move on, the way to unlock bootloader is to use MTK Client. I have unlocked bootloader on both of these devices and made twrp for A501DL

You have no clue what you are talking about good sir, I suggest some research

Perhaps, good sir, I am incorrect on this point. If that is the case, I have no problem admitting I'm wrong and apologizing for the misinformation. So, for what i have been able to gather, device owners are using an MTK-based utility to dump the partition images. In turn, the boot image can be patched for Magisk systemless root and flashed back to the /boot partition using the same MTK tool. I'm also hearing about a Hydra tool that can unlock the bootloader. @PizzaG does this sound accurate? After all, good sir, since you called me out for being wrong, please clarify these points. Thanks

You are correct good sir on MTK Client. Hydra is a Paid solution people usually use to network unlock their devices and I know little to nothing about that aspect. I know for a fact that MTK Client will Bootloader Unlock Both the A501DL(device I own) as well as the A502DL(a user in my telegram group had one).

The process looks like this for MTK Client.
-Make a dump of the whole device
-Magisk Patch the boot.img(boot.bin)
-Use MTK Clienbt to Flash patched boot.img
-Enjoy!!

I have twrp and custom stock for A501DL. Since I don't have the A502DL, I personally have done nothing with it.

here is the github link for MTK Client

@PizzaG thank you much for the information and the link. This is splendid news that a TracFone branded TCL device can at last be exploited..I look forward to unlocking mine.
Again, I stand corrected for my misstatement and truly appreciate your guidance.

no worries bud, happy to help whenever I can. I can also dump and build twrp. If you need a hand, join my Telegram and I'll see what I can do. Best of luck on your journey
