[Request] A7 2017 Edit Stock Rom

[msoaresantos]

Hi,


I have an A720F that uses the A720FXXU2AQFA ROM (ZTO). I need to use the old ROM A720FXXU1APLI (ZTO). For Odin it is not possible to downgrade, it gives error.
I can only upgrade to Odin, not to CWM or TRWP.
I need a solution and I can make a donation through Paypal to those who can help me.

Thanks! Sorry for my bad english!

I have a sales application that makes bluetooth connection with a card reader and marks the placement. The only version that works is the A720FXXU1APLI, then upgrade, does not work 100%. Sometimes it does not connect to BT and it also stops geolocation. I have little knowledge and every time I try to go back to the original ROM it gives an error, I researched and I saw that the problem is that the version on the phone is bigger than the one on the binary. I only know how to use Odin.
I need to be able to install an older binary on my cell phone, downgrade but odin will not let me.

In short, I need to install an older official stock rom but Odin does not allow it.
System Rev. Check fail Device: 1 Binary: 0

I do not know how to do it, I have little knowledge.

Not possible unless you modify the .tar.md5 by removing the .bin files in it, then tar it up and flash in odin.
The secure bootloader (sboot.bin) won't allow the downgrade of itself. Needs to be left at U3.
Modem (modem.bin) must also be left at U3, because downgrade modem to U2 while keeping the U3 bootloader will leave you with unknown network or IMEI loss untill upgraded again.
Same with cm.bin. It needs to be left at U3 afaik.
