I tried it on windows and Linux both and then again in windows and Linux running in virtual box and then tried to test point into brom for like 4 hours and nothing lol I also tried 4 different mediatek boot mode tools it's looking hopeless
Hmmm, before updating I was able to get my A21 to BROM mode using a Debian distro by first running a command in mtkclient, then plugging in the powered off phone and letting mtkclient crash the preloader in order to get to BROM mode. After that then the command will execute, ex: "python mtk printgpt" would get me the partition layout of the phone. I was able to make a full dump of the phone and even ran the bootloader unlock command on it, which didn't unlock the bootloader unfortunately lol.
For somebody who has been out of the rooting game for years, can you explain to me this BROM mode?? I have to remove the back of these nonremovable battery phones? I remember when the backs and batteries of Androids could be removed like old radios. Idk how to remove the back of my Galaxy A12 (A125U). Can you point me to a guide as to how to do the BROM mode? I've never heard of it
I do mean A21 as I own one, it was only sold in the USA and Canada. It has the same CPU as the A12.
You didn't think to mention or refer to a guide on how to boot into BROM mode? Which involves opening the back and unscrewing ridiculously small screws? Why does no one mention these things? Root guides are **** compared to 2012 root guides and people should feel bad for failing to specify detailed instructions.
Probably, but you would need a binary 2 BL from binary 2 A125W firmware to try

Flashing the preloader back to the phone may fix the brick, give me some time to figure out a processIn reference to the SM-A125U on A125USQS3BVA2 , after spending several days and every piece of unlocking /mtk / Samsung tool known to mankind I think it's safe to say that this phone can NOT be downgraded using combination file, test point, or any other method I've found online at the moment but I did find this software (which I have no idea about whether it's safe or not, but I'm about to try it so I will let you all know) but the information it has listed might be useful to someone that understands it better than me , it goes into detail about what changes were made and why we can't unlock with other methods and how to do it a new way , So I will try it, but if anyone else understands the instructions, I'm more than glad to help if you need it with testing , etc.

**Update **.. even though this tool works and says it's for our specific device and even has dedicated buttons for it ...for some reason I can't get out of brom mode now , phone is completely bricked won't boot at all and won't respond to anything other than just showing up as brom mode. Do NOT use this unless you know what you're doing .
thats exactly what the issue is lol when i was flashing things it wanted a preloader and theres 2 different ones inside the stock firmware one is like titan rat and then theres another one and i guess i flashed the wrong one but i have no idea how to flash a preloader being that it cant even be detected , what i really dont understand is am i using sp flash tool to flash since its mediatek or am i using odin...
contained within the official firmware there is preloader.img and also preloader_k65v1_64_bsp_titan_rat.bin im assuming i flashed the wrong one but i cant remember which ..i cant get sp flash tool to work at all no matter what i try even tho my drivers are right also so i have no clue at this point lol. ***Edit*** finally got it fixed it, just needed the right preloader and it's working again but back to square one with the root lol
What is the right preloader??? Please link it to me this phone been dead for at least 2 weeks
its just preloader.img inside the stock firmware just download the firmware and extract it
I want the one you used. I've already extracted the one in the preloader image too but it doesn't work. If yours was for bit 3 can you please upload it for me I'd appreciate it very much buddy
Thanks for helping. I rooted 4 note 4s and they all finally give out so I am going to try a newer phone
