No signal on MTK A-only SAR with recovery mode Magisk

[S190762]

Magisk installed to recovery partition on a A-Only system as root mediatek device. The device has no signal, and no IMEI number. Wifi works.

Tried all versions including stable/beta/canary/canary debug/ianmacd latest. No modules are installed. Attempting to dial a number says "Mobile network not available"

Dmesg is full of the following error: [33.239513] [1:init] Could not find service hosting interface vendor.mediatek.hardware.radio@3.0::IRadio/imsrild1 [33.240113] [1:init] Received control message from 'interface'start' for 'vendor.mediatek.hardware.radio@3.0::IRadio/imsrild1' from pid: 337 (/system/bin/hwservicemanager)

This seems an awful lot like a ROM issue

Are you on stock? Did you only flash magisk, did you modify ANYTHING else?

Because I've never seen magisk cause this....

And BTW what device?

[S190762]

The rom is completely stock, there are no custom roms for my device or TWRP.

It is a Nokia 1 Plus running Android 9 Go Edition. It came with Android 9 so has A only system-as-root. The boot.img doesn't contain a ramdisk and magisk doesn't work if i try to patch the boot.img

[nebulakl]

Same phone, (possibly) same rom and same issue on magisk 16b40096.

All logs gathered with SysLog app and magisk logs: https://gist.github.com/nebulakl/fe94a607a5188feeae942c384234ae9f

stock firmware package that may help analyze the issue https://drive.google.com/open?id=1ZNEgRw33-4DlLkY6S_DbytOaZpaBprsh

[hasnainbhai77]

Having same issue on infinix smart 3 plus x627 on pie please solve this issue

[bauner]

I have the same issue on Redmi Note 8 pro

I used magisk manager to patch the stock boot.img with the recovery option and dm-verity off and flashed it with fastboot to the recovery partition (any other option caused a bootloop)

[unresolvedsymbol]

Can confirm Magisk v20.1 completely breaks the radio on Essential phone with stock Android 9, strangely it fixed it on some Android Q custom ROMs and stock betas but all of this is paranormal 😂

[osm0sis]

Out of curiosity, while unrooted with radio working can you adb shell into the ROM that Magisk was breaking radio for and give the output of mount ?

Interestingly, despite Magisk Manager shows Magisk is up to date, I was not able to gain root access. Magisk Manager also shows my device requires additional setup but whenever I tap ok I only get setup failed message.

Just keep trying setup, sometimes takes a couple tries. But anyhow that's outside the scope of this issue, open another one if you continue to have issues @nebulakl

[fawazahmed0]

Have you flashed dm-verity disabler anytime? last time I had problem with that. Just incase you flashed dm-verity disabler, I have the fix for it.

[iscle]

Why was this issue closed? I have the same problem on a clean, source-built MediaTek MT6739 system running SAR Android 9!

It might be because the proper init files are not being called when booting from the recovery partition instead of the normal boot partition using system-as-root? Looking into it now.

I've taken a radio logcat with and without magisk, and noticed that NVRAM and RILMUXD, services that are started by the init files, are not logged when running Magisk from the recovery partition.

[ShaDisNX255]

I guess it must be a Mediatek problem Samsung A10s, A-Only, System As Root and Android 9 also experiences this

When you reboot normally, signal returns but you lose Magisk of course When you reboot + Magisk by using recovery hot keys, Magisk works but signal is gone

[buffer1900]

infinix smart 4 x653 same problem.Any fix for this ?

[Axeltherabbit]

Same issue on blackview a60, mediatek chip, the IMEI is null in the recovery and fine with a normal boot. Lineage 19.0, android 12

[arklese1zure]

Hi guys, I think me and some oher people are finding this problem on Galaxy A32 phones (Mediatek MT6769V). What's strange is that the problem persists even after reflashing with stock ROM.

Has anyone found any possible solution?

yeah, my A32 4G with the same MTK Helio G80 (MT6769V) chipset has the same problem, and also, people with a22 and a32 5g are mass reporting this issue

[dronkit]

+1 Same problem with the samsung A325M (a32 4g), no IMEI or baseband a few days after rooting, flashing stock rom doesn't fix it. Updated Magisk up to canary 7cfce9ff, no fix. My dmesg has lots of:

Control message: Could not find 'vendor.samsung.hardware.radio.bridge@2.0::ISehBridge/slot1' for ctl.interface_start from pid: 440 (/system/bin/hwservicemanager)
Control message: Could not find 'android.hardware.radio@1.5::IRadio/slot1' for ctl.interface_start from pid: 440 (/system/bin/hwservicemanager)
Could not find 'vendor.samsung.hardware.radio.channel@2.0::ISehChannel/imsd' for ctl.interface_start from pid: 440 (/system/bin/hwservicemanager)
IDK if related but my magisk log has lots of
626   628 E : unlock mmcblk0p42 failed with 13: Permission denied

for several devices.

Please ask me for any files/logs that can be helpful!

[dronkit]

I was able to fix it on the a32, working so far https://forum.xda-developers.com/t/rooted-a325m-suddenly-no-imei-no-sim.4386753/post-86588571

IDK what is the cause, but mayb this will help the "victims" or the fixing of the issue

[osm0sis]

Could be worth trying with 24305, original init handles a lot more now.
