Hi, I have Moto G7 Power xt1955-4 with Android 10 Q, unlocked for any GSM carrier, used on T-Mobile network. I unlocked the bootloader and i'm trying to install TWRP recovery image into it. Mostly I follow this guide https://www.androidinfotech.com/root-moto-g7-power-ocean-android-10 . I got the latest available for my phone TWRP -3.5.2-10-ocean from https://dl.twrp.me/ocean/twrp-3.5.2_10-0-ocean.img.html, switched my phone into fastboot mode so it's visible to 'fastboot devices" command, then i run "fastboot boot twrp-3.5.2_10-0-ocean.img" Phone reboots to temporary TWRP now, shows "Enter password for User [0] - ... Data successfully decrypted".
Now, when I try to permanently install TWRP, I got a problem, even though everything looks ok, no error messages: first I installed Disable_Dm-Verity_ForceEncrypt.zip file, with Success. Then I installed twrp-installer-3.5.2_10-0-ocean.zip via TWRP itself: it shows "######## TWRP installer for A/B devices ######## Running image patcher on boot_a... Running image patcher on boot_b... Image patcher complete! Done installing TWRP ***Note: You are now unrooted!*** Updating partition details... Success!" - note no errors here.
BUT when I reboot into recovery mode again, I see only TWRP logo, then phone beeps for 1 sec, and nothing happens after that, no menu shows up, no prompt to "Enter password for user" as before. No response from screen touches. Only reboot helps.
So I understand that TWRP was not installed correctly. What did I do wrong?
Any suggestions will be appreciated.

You should join and follow the G7P (Ocean) telegram group if you haven't already done so. Any questions can be asked there or are already answered in the #notes section. As far as twrp goes because the device is a/b type I never install the zip. I connect to pc and fast boot twrp image to flash ROMs.

Thank you Skippy12359, I found just "Moto G7 Power Ocean/River Channel" on Telegram, with 10 subscribers - is it the one you mentioned?
My goal is to install Magisk-v23 on my phone, to complete rooting procedure. I was going to use TWRP for this, and install it via zip file. But if I use temporary TWRP and just install Magisk-v23.0_renamed_apk.zip, after reboot Magisk app shows "Installed" status as N/A! Apparently it doesn't work as intended... So I thought that permanently installed TWRP would give better result.
UPD: Also I see "Moto G⁷ Power | Builds™" channel with 445 subscribers, and "Moto G⁷ Power | Discussion™" with 379 members. Signed up for those!

There's a Moto g7 power discussion group and a Moto g7 power builds group. If you're new to flashing ROMs put all your ROMs, magisk, gapp files on your sdcard. Then fastboot twrp and flash ROMs, magisk from there. You can install the twrp zip if you want just found it easier not to because it gets overwritten anyway because the device has no separate partition for recovery like an A- only has for example.

Actually this method (fastboot to temporary TWRP, then install magisk.zip file from sd card) works! I was able to install Magisk this way, and first time it boots normally, Magisk shows Install status v23, CheckRoot app shows that everything is ok. But on second reboot i'm getting into bootloop :( After Warning message and 5 sec wait my phone beeps and reboots.

Magisk has an uninstall zip file if you have boot problems. Once magisk is uninstalled from recovery it should boot up fine. There is also a magisk canary version on github which should fix any boot issues after flashing. You need both the magisk zip and the magisk app installed to have full root

I try Magisk-Canary (after uninstalling Magisk v23 by renaming zip file to uninstall.zip and run it via TWRP) from https://github.com/topjohnwu/Magisk, the result is the same- first boot is Ok, Magisk app shows that it's installed (Magisk status 5d6d2417 (23015) version installed), but second boot gives me bootloop...

I haven't used stock for over a year and I don't recall having any problems rooting or ever had a boot loop on rooted stock Q. Also I've never needed to patch a boot image to get root. I just reflashed stock firmware, installed all the apps I wanted and fast boot to recovery. Flash copy partitions zip and then flash Magisk. After reboot to system I install Magisk app and I'm done. Always worked for me. Rooted and no reboots.

I assume that you have Moto xt1955-4, correct? Which ROM you have installed then? At the time of Magisk installation , was it custom ROM or original stock ROM on your phone?

I have the usa model of the same phone xt1955-5 and have always had it rooted whatever custom ROM or stock firmware used at the time. I'm currently on AICP 11 official custom ROM but switch frequently from Arrow, Colt and other ROMs.

Hey Skippy, When I originally got the phone, I bought it outright from Cricket. A Supra, but still the same as G7 Power.. No payments. No years agreements. Now that it is no longer supported, I want to unlock the bootloader and install a custom rom. Setup ADB and went to Motorola's website for the unlock code. I get "Does not qualify for unlocking." For the above two reasons, I'm a bit miffed. Has anyone found a work-a-round for this? I got up at 6 AM. All day studying and learning how to do this. Only to get the message. "No you can't. Sorry. Notta". And with Motorola's piss poor support policy, it grinds my gears.

I have the TMobile variant codenamed Ocean, so I'm not going to be much help on your question. I suggest you ask in the Moto g7 power discussion group on telegram. I'm sure someone there can let you know if the cricket variant is unlockable or not. Good luck

Thanks for the quick response! I don't use Telegram, but I guess I better get signed up. I wish there was a repository of, an HCL of sorts, where people can refer to before buying phones to avoid these issues.
