"No Sim Card detected" (due to TWRP backup restore) fix through fastboot commands?
Yesterday I had to restore my phone to a previous ROM (stock MM) from RR 5.8.5 Nightly. This was due to my working from home and needing to generate an RSA soft token, which is set up on an app on the backup, yadda yadda... Anyway, my restore worked fine, and I was able to generate my key and work from home.
However... when I went to use my phone, I noticed that the SIM card was no longer detected. I tried restoring my RR rom, and it too would not detect my Sim card.
In my attempts to find a fix, and then my attempt to restore the stock firmware and bootloader (that seems to be the only fix), I managed to royally hose my phone by attempting to flash the Full Stock LL ROM, which failed and must have overwritten the bootloader and recovery partitions. Trying to turn the phone on resulted in a vibration, but only a black screen. I was able to unbrick the phone using various guides I scrounged up and utilizing XFSTK and IntelSOC drivers, which must be installed when Windows 10 is booted with the special option to install unsigned drivers enabled (hold shift when you click restart, then option 7). I can post what I went through when I get home to my files and stuff if anyone requests it. Asus Flash Tool refused to flash the raw firmware (wrong format my ass), so I had to manually run the fastboot options. Everything was hunky dory after this.
Every fix for the SIM card issue pointed to reverting to stock firmware, which is what I did. However, I'm thinking there must be some key partition that I flashed in fastboot that revived the SIM. I performed the below commands from this thread . Does anyone see a command that screams "I'm fixing sim card issues"?
1. fastboot devices ( see if it is recognized: else plug out usb and plugin again)
2. fastboot oem erase_osip_header
3. fastboot oem start_partitioning
4. fastboot flash /tmp/partition.tbl partition.tbl
5. fastboot oem partition /tmp/partition.tbl
6. fastboot erase system
7. fastboot erase cache
8. fastboot erase data
9. fastboot erase APD
10. fastboot erase ADF
11. fastboot oem wipe splashscreen
12. fastboot oem stop_partitioning
13. fastboot flash splashscreen splash_sign.bin
14. fastboot flash token MFG_BOM_Full.bin
15. fastboot flash ifwi ifwi-prod.bin
16. fastboot flash boot boot_sign.bin
17. fastboot flash recovery recovery_sign.bin
18. fastboot flash fastboot droidboot_sign.bin
19. fastboot flash APD APD.img
20. fastboot flash system system.img
21. fastboot reboot

If we can get the fix for an undetected SIM card after TWRP backup down to a few (or single) fastboot command, it'd be a nice convenience for us all.
Alternatively, does anyone know of a proper way to restore TWRP backups without losing SIM card detection?
UPDATE SECTION
I had found this site while searching for a solution yesterday, and it has the following fastboot commands for fixing the sim issue:
adb reboot bootloader
fastboot erase modemst1
fastboot erase modemst2
fastboot reboot
Click to expand...
Click to collapse
So in this case, the modem partition is being erased. But I don't see anything in the unbricking fastboot commands that erases the modem partition. Am I just missing it? I could see my IMEI in Sim Slot 1, so maybe it wasn't a modem partition issue.
-------------------------------------------------------------------------------------------------------------------
Found this thread (How did I miss it before?): https://forum.xda-developers.com/zenfone2/general/guide-how-to-zenfone-t3173314
The minimal boot options he listed are all in TWRP 3.1.1-0. The only thing I was missing before was config... I'm thinking that might be the key to preventing this. Next step is to determine if there's a config partition, and what happens when you do stuff to it (and ultimately how to restore the partition when you don't have a TWRP backup on hand).
So when I got this device I went to root it and found there's not very good documentation on what to do to get root and recovery installed so after many boot loops and reinstall of firmware here is what I did to gain root and TWRP and have a stable environment. You will need to use ADB & Fastboot commands please install either this : https://forum.xda-developers.com/showthread.php?t=2317790 or https://forum.xda-developers.com/showthread.php?t=2588979 or you can install from here: https://developer.android.com/studio/releases/platform-tools. you will also need the Motorola drivers located here: https://support.motorola.com/us/en/solution/MS88481. Once you have obtained these you can proceed with the bootloader unlock. I have the unlocked version of the Motorola G7 Power so I was able to fallow the sets here: https://support.motorola.com/us/en/bootloader/unlockyourdeviceb. If you have a different variant I'm not sure if your able to unlock your bootloader please try and let me know in this thread. I AM NOT RESPONSIBLE IF YOU SCREW YOUR DEVICE UP OR FOR ANY DAMAGE TO YOUR DEVICE
Bootloader unlock steps:
1. On your device go to Settings and to System, Then About phone and click " Build Number " until you unlock developer options.
2. Back out one step and click the Advanced tab and then click " Developer Options ".
3. Once in developer options " OEM Unlocking " turn off " Automatic Updates " and enable "USB Debugging".
4. Once you have done USB Debugging open the start button type "CMD" and open a command prompt.
5. Once in command prompt type " adb devices " make sure you authorize the pc on the phone. then type in command prompt " adb reboot bootloader "
6. Once in bootloader type in command prompt " fastboot oem get_unlock_data " from here fallow the directions on the Motorola Bootloader Unlocking page: https://support.motorola.com/us/en/bootloader/unlockyourdevice
7. Take the number given to you by Motorola and type in command prompt " fastboot oem unlock CODE FROM MOTO " then enter the same command again and your device will be bootloader unlocked.
TWRP & Magisk install:
This is where I found it to be difficult to get things right either I would bootloop or I wouldn't be able to unencrypt my sd card in TWRP so I couldn't read things right all sorts of dumb issues. All the files I used are attached so please let me know if this works as well as it did for me. Please download the TWRP .img file it was too large to attach: https://dl.twrp.me/ocean/ Also make sure that your command prompt is in the directory of your stored files.
Here are a list of commands to get TWRP and install Root please be in bootloader mode to start this process.
1. fastboot boot twrp-3.3.1-2-ocean.img
2. In TWRP go to the wipe option and select the format and type " yes " once it has done that go back to the main TWRP page by hitting the home bottom and select Reboot and select Reboot Bootloader.
3. fastboot boot twrp-3.3.1-2-ocean.img
4. Once in TWRP adb push twrp-installer-3.3.1-2-ocean.zip /tmp/ then click install and navigate to the /tmp folder and install the TWRP .zip file
5. After you install TWRP do this : adb push Magisk-v20.1(20100).zip /tmp/ then navigate to your /tmp folder and install Magisk .zip file
6. After you install magisk you can reboot the system and let it sit it might loop once or twice but it will boot. I did the force encrypt disable with the attached zip file then i rebooted.
Also I found it best to do this with a fresh installed firmware that hasn't been booted yet I downloaded the firmware/ROM from here: https://mirrors.lolinet.com/firmware/moto/ocean/official/RETUS/ here is a list of commands to copy and paste into command prompt please make sure your device is in bootloader/ fastboot mode.

Well i messed it up some how. my phone would boot loop three times and then go back to the twrp screen. after 30 minutes of messing with it i gave up and factory reset it via the adb platform tools.
Got it to work but had to start fresh as said at very bottom using retus version, I did all that then step by step but i booted once just to enable usb debugging of course, already had oem unlock but then right back into recovery flashed magisk and disable dm verity both back to back before reboot and all went fine cant get ota ofc but surely better roms will start showing up soon and I wont give a crap about stock anymore.

I am gonna check one thing I had it all working another method before but after installing something thru magisk it soft bricked I think it was vanced youtube maybe also cant seem to find a way to get vipre to work sadly.
Question
Does this method bypass the screen lock password on the phone? I have this phone that is locked with a passcode, so I can't easily get it into developer mode. Sorry, I'm a total newbie to this but am trying to learn. Thanks in advance!
A tip for linux users. If you are getting "< waiting for any device >" after the "fastboot oem get_unlock_data". Ctrl-c to exit the command. Su to root and then "fastboot oem get_unlock_data".
I give up, SIM stopped working after multiple failed attempts at installing Custom ROMs, even so much as installing Magisk+force encrypt disable brings up Factory data reset screen. Now my SIM doesn't even work on another stock phone for some reason, since the ban that apparently exists, if applied, should be IMEI-only, and somehow it works on a Custom ROM+Magisk device of mine. Going back to stock with locked bootloader I guess
SIM stopped working on G7 Power = neither SIM from two different carriers, one that's never been on a rooted/unlocked bootloader phone, don't even show up as a grey signal icon, tried both slots.
My SIM not working on another stock phone (G7 Play) = not recognized at all, but at least it recognizes there's a SIM card in there, grey signal.
Working fine on G5 with Magisk, Xposed and OmniROM
So maybe I banned both the chip (?) and IMEI, but still for some reason it works on another bootloader unlocked phone

From what I've been able to tell, the SIM cards are locked via IMEI (from MetroPCS I assume?, cause that's what they do), and will appear invalid, but should show the phone number in the settings. It should also say out of service, unless inserted into the phone that it originally belonged to.
I have an E5 Play, and unlocked it using the device unlock app built-in from MetroPCS, after 3 months of service (maybe 6 I forget). After that, I could throw in other SIMs. But the phones those SIMs would come out of, they couldn't read the metro card. They said invalid. But it still recognized it was a card, and showed phone number in settings. Said out of service.
After realizing this, I found out you can change devices in the website real quick, and that should solve the "invalid SIM" issue.
Possibly some custom ROMs lack what restricts all this in the first place, and the Sim must be valid because it's a SIM, in service, and the proper network. No clue there. What carrier are you on?

The thing is, "stopped working" literally, it doesn't have out of service, phone number, no signal, not even the "emergency calls only", heck I can't even find my IMEI in settings nor *#0606#, I think that's what's causing the problem. This SIM also came from that Custom ROM device (originally inserted there, but bought as a standalone data plan)

If you're talking about how it showed up like that on the G7 Play it used to work just fine in there, and no, that's not the original phone, it's just a phone I used to test if my SIM was still working

In this phone, G7 Power, it doesn't even recognize a card is in the tray anymore (unlike the G7 Play which at least knows there's one and G5+Custom ROM, in which it works)

Not that it's gonna help much but OI (Brazil), and if that's on Motorola support page my G7 Power is main phone already.
Is the force encrypt disable necessary? And what does it do?
So, I have successfully rooted my Moto G7 Power by using the method above, but i tried not doing the "format data" and fortunately, I have rooted my phone. For the 1st attempt, I kinda soft-bricked my device by doing the steps briefly, my phone would always bootloop back to recovery mode, but after not doing the "format data" step, it led to a success. So for anyone who are currently experiencing bootloop, flash the stock firmware to your phone and root it again by using the method above but don't do the "format data" step. (flashing the stock firmware would not re-lock the bootloader, so you can try to root your phone again easily.)

If it's same thing as always then you're still using "adb push magisk adb push Magisk-v20.1(20100).zip /tmp/". There's no "but I'm not", if it's indeed the same error as before you're messing up on the syntax. Make sure you've put Magisk inside Minimal ADB folder, rename it to magisk.zip and run "adb push magisk.zip /tmp/"
why is magisk pushed to tmp and not to internal storage . Why not just push magisk to internal sotrage and just install that way through twrp or that wont work. just wondering.
Anyone tried this on XT1955-4?

I LOVE IT!!! :good:
I flashed my redmi note 8 pro indian version with miflash, and downgraded to android 9 from 11 to install Ubuntu touch.
Ubports installer still didnt recognize my phone I am guessing cause it was Begoniain(india) as opposed to Begonia(Global) that is supported.
But my problem is I want to go back to Android, and I dont know how to go back, I didn't have any recovery tool installed before installing Ubuntu Touch, now Ubuntu is very buggy, and I can't seem to install TWRP. I have no other recovery tools installed, just fastboot. I guess I should hvae installed twrp before installing Ubuntu Touch. I want to know how I can go back to android or to any other supported custom rom.
Thank you.
whats wrong with fastboot?
Hey, thanks for replying. I followed the steps in this video
which is a very accurate video i found after searching for many videos.
basically he asked to download the right TRWP, then ADB platform tools, then the ADB driver found here

this seemed to work for many people and everything went well. but I just can't boot to twrp it just takes me to the ubuntu touch screen and i log back in to UT

yes i think so, i think i should've installed twrp before that was the mistake, but i'll have to format this somehow
Did you try flash by mi flash the rom that you used to downgrade?
yes this is the first thing i tried, the same procedure i used to downgrade to 9 with mi flash, but when i do that it flashses in just 1 second, and gives success message, i was like it can't be that fast, but that happens everytime, so i figured somethings wrong. I turn on my phone and it's not flashed, it boots to ubuntu touch, but now even that's not happening, now it just keeps restarting after xiomi unlcoked screen.
i want to install a custom rom that goes best with my phone, i dont really want andriod to be honest, but need to have something installed to boot atleast, and I dont really mind if the phone goes dead, so i am not worried about experimenting on it

I believe that error message is misleading. It should mean
FAILED (remote: 'No such partition.')
you probably meant 'userdata' partition. however, I do not recommend fastboot erase cmd.
you should be able to enter fastboot mode with Volume Down button. instead of flashing TWRP into recovery partition (where it belongs) you could cheat bootloader and flash TWRP into boot partition instead. this will boot into TWRP recovery without Volume Up Button.
Code:
fastboot flash boot twrp.img
once in TWRP you can format Data, flash boot partition and install TWRP recovery.
probably easiest way is, create backup of boot + recovery from TWRP backup menu. that will create two files, boot.emmc.win + recovery.emmc.win in TWRP/Backups/<serialno>/<date> directory. just create another directory TWRP/Backups/<serialno>/my_files and place your files in there (rename boot.img = boot.emmc.win and twrp.img = recovery.emmc.win) then restore 'my_files' backup from menu.
then you can install any ROM from TWRP via System Image. Note that's android device, you can only install android. even ubports Ubuntu touch is not linux, it is just some gui build on top of android kernel to give you linux-like feelings.
