About rmt_storage patch

[jason-akw]

Hi,

I'm trying to patch rmt_storage for my OP7Pro now.
I tried many rmt_storage files from other phones with SDM855 chipset.
But the modem won't boot.

I also have an OP5T phone, and I used the file that you provided, it works without any issue.
Which device's file you extracted for OP5T?

I think I can try the file from that vendor's SDM855 device.

Thank you.

[denysvitali]

Thank you for opening the issue:
I've extracted my rmt_storage file from a Pixel 2's vendor partition if I recall correctly.

Unfortunately I don't have access to an OP7 Pro: you can probably use the Sony Xperia X1's / Xiaomi Mi 9 vendor partition - it should work.

Give me 10 minutes

rmt_storage is running, but modem doesn't boot up

[denysvitali]

Try to manually crash the modem (go to the dialer pad, write *#800# and click on Crash Modem)

[jason-akw]

Tried, don't work.
I also can not see the version of modem, it shows "unknown" on system settings.

[denysvitali]

Can you try by pkilling the process and starting it again a couple of times (pkill rmt_storage && sleep 1 && /vendor/bin/rmt_storage &)?

[jason-akw]

Tried about 20 times, modem still down.

I also tried Pixel 4's rmt_storage, also don't work.

[denysvitali]

I need to do some reverse engineering on the binary I provided you: maybe it acts like the Oneplus' one and it looks for a similar device (therefore the patch is useless).

In the meantime, you can try with another device's rmt_storage. What version of Android are you using?

[jason-akw]

I'm using Android 10 (OOS Beta 6).

I'll try other binary tomorrow.

[jason-akw]

These days I tried binary from Mi 9T Pro, ASUS Zenfone 6, ROG Phone 2.

Now I got these errors from modem.

What kernel version are you using? Can you post here the original rmt_storage file?

[jason-akw]

stock 4.14 kernel from OP7Pro_O2_BETA_6.

[denysvitali]

Sorry for the late reply, I'll look into it ASAP

[Abyss777]

Hello @denysvitali
Have you had a chance to look at rmt_storage from op7pro ?

[denysvitali]

Unfortunately not yet :(

[ghost]

Hello Denys, do you have any patched rm_storage for snapdragon 845? i need for my Google Pixel 3 that keeps replacing my modded 00028874. Thank you

[jason-akw]

Interesting. The rmt_stroage from Pixel 2 can use on the OP7Pro with OxygenOS 11 :)

Would you mind sharing which specific OTA version you took the rmt_storage from? Thank you!

Just use the file from this repo: https://github.com/denysvitali/ca-combos-editor/blob/master/resources/rmt_storage_patch/op5t/oos/9.0.9/rmt_storage

So strange, works on A11 but not A10.

Hi!

Is file in this repo worked on A11 ?
