(10-09-2021, 02:27 PM)iammclovin804 Yeah I've already tried that. I'm having the exact same issue as OP was so I was hoping to get the preloader they used to try.

check their profile, you can try sending the OP an email pointing out the post here, who knows maybe maybe he might still have the file(s)

Hey guys! And sorry for being so difficult to get in contact with. And another sorry for not posting the correct preloaded and documenting my findings. I've just been somewhat busy but now you have my full attention.

So here goes...

The common preloader posted here and on many websites was not the one for my device. The common one uses Samsung memory chips but it seems that later on they switched to Hynix memory chips, which my device has.

Here's an EMI readout from the common preloader file:

Quote: EMI : DEV : MT6765
EMI : SRC : preloader_k62v1_64_bsp.bin
EMI : CNT : 0004
EMI : [00] : eMMC : DDR3 : ID : 150100474436424D42 : VEN : SAMSUNG | DEV : GD6BMB : RAM : [ 3.00 GB ]
EMI : [01] : eMMC : DDR3 : ID : 150100524436344D42 : VEN : SAMSUNG | DEV : RD64MB : RAM : [ 4.00 GB ]
EMI : [02] : eMMC : DDR3 : ID : 150100524836344142 : VEN : SAMSUNG | DEV : RH64AB : RAM : [ 4.00 GB ]
EMI : [03] : eMMC : DDR3 : ID : 150100514536334D42 : VEN : SAMSUNG | DEV : QE63MB : RAM : [ 2.00 GB ]

And here's mine:

Quote: EMI : DEV : MT6765
EMI : SRC : preloader_k62v1_64_bsp.bin
EMI : CNT : 0005
EMI : [00] : eMMC : DDR3 : ID : 150100474436424D42 : VEN : SAMSUNG | DEV : GD6BMB : RAM : [ 3.00 GB ]
EMI : [01] : eMMC : DDR3 : ID : 150100524436344D42 : VEN : SAMSUNG | DEV : RD64MB : RAM : [ 4.00 GB ]
EMI : [02] : eMMC : DDR3 : ID : 150100524836344142 : VEN : SAMSUNG | DEV : RH64AB : RAM : [ 4.00 GB ]
EMI : [03] : eMMC : DDR3 : ID : 150100514536334D42 : VEN : SAMSUNG | DEV : QE63MB : RAM : [ 2.00 GB ]
EMI : [04] : eMMC : DDR3 : ID : 90014A484247346132 : VEN : HYNIX | DEV : HBG4a2 : RAM : [ 3.00 GB ]

As you can see, my phone has an extra EMI setting for the Hynix memory chips. I'll attach my preloader below. And lastly to keep track of things, here are some file hashes:

Quote:[Samsung Only Preloader]: SHA-1: 73b0d9ff7c9aee9af0853cbfd76b7992ec6258aa
[Samsung+Hynix Preloader]: SHA-1: 4126c81d98d6d03a4bb7eb6c1b2422dc9a05aba4

Thank you so much for posting this! Finally got my preloader flashed back with your file so I can work on getting the phone back up and running.

I'm glad to hear you got it working! And I'm here if you need help with anything else. @X3non can you please add this preloader to the thread with the original one. And also indicate that this one is for the Hynix chips while the original is for Samsung chips. And thanks.

Thanks for sharing the preloader

curious, is the device able to boot to homescreen using preloader @haku shared and the rest of the firmware from the firmware you downloaded here?
