I tried to install the October security patch, I think I was all working perfectly fine with the August security patch.
I get an error reflashing in the following stock roms, my signal is dead:
"XT1922-4_ALJETER_OPENMX_9.0_PPPS29.55-25-2_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml" and
"XT1922-4_ALJETER_AMX_9.0_PPPS29.55-25-2_cid50_subsidy-TELMXLA_regulatory-DEFAULT_CFC.xml"
So, the one that actually boots my phone correctly is:
"XT1922-4_ALJETER_OPENMX_9.0_PPPS29.55-35-12-5_cid50_subsidy-DEFAULT_regulatory-XT1922-4_CFC.xml"
And now I noticed in settings shows up that my software channel was amxmx and changed my stock rom to:
"XT1922-4_ALJETER_AMX_9.0_PPPS29.55-35-12-5_cid50_subsidy-DEFAULT_regulatory-XT1922-4_CFC.xml"
According to https:// mirrors.lolinet.com/firmware/moto/aljeter/official/AMXMX/
this was supposed to be the latest firmware updated for me (I guess...?)
I'm scared to root my device now (cause' I really want to) because I can't stop messing my boot.img or something like that, I can backup my data and personal stuff, but my phone wont accept a good firmware, flashing TWRP correctly and installing Magisk.
Everytime I try to follow the guide with different versions of the elements needed, that bootloop shows up with the "80012A99-867FDA48-4E357816-0E549F..." thing.
What am I missing so I can get a "clean root" process?
1. I'm shutting down my moto G6 play.
2. Entering Fastboot mode by clicking volume down and power keys.
In fastboot I get this captions.
AP Fastboot Flash Mode (Secure)
BL: MBM-2.1-aljeter_retail_b1f322d-190926
Baseband: M8937_31.39.05.93Z JETER_LATAM_CUST
Product/Variant: jeter XT1922-4 32GB P4
(some more info as serial number, cpu, emmc, dram, console, tools mode config)
flashin_unlocked
transfer mode: USB Connected
3. Now I boot twrp
fastboot boot twrp.img
TWRP runs and shows
Mount
Decrypt Data (I touch Cancel and then proceed)
**Swipe to allow modifications (I swipe)
4. Try to backup but cmd shows:
"remote object '/dev/block/platform/soc/7824900.sdhci/by-name/boot' not a file or directory
5. Format my data in Wipe Format Data, and typed "yes"
6. Used
adb reboot bootloader to reboot.
7. Now I flashed
fastboot flash recovery twrp.img and not getting any Decrypt Data screen anymore.
8. I allow modifications.
9. I put my archives in sd card.
Disable_Dm-Verity_ForceEncrypt_05.21.2019
Magisk-v19.1(19100)
10. I go to install and install both zips in that same order.
11. Reboot System.
12. Black screen shows up with "Bad key" caption
13. Moto G6 reboots fine, like new.
14. Configuring my device.
15. Checking root with root checker.
16. Root confirmed.
So, I think the solution was to replace the archives in the original guide with:
Disable_Dm-Verity_ForceEncrypt_05.21.2019
Magisk-v19.1(19100)
Hope this helps everyone else. Or me, in a future
