Modem crashes on vanilla T-Mobile 7T Pro - OnePlus 7T Pro 5G McLaren Questions & Answers

Hello here.
I recently (1-2 weeks ago) bought a new OnePlus 7T Pro McLaren from T-Mobile and I'm really happy with it. It came with Android 10, but then I installed Android 11 via OTA.
I did no roots, no flashes, no other modifications.
it worked with Verizon SIM-card but then I switched to T-Mobile.
Starting a day or two after I switched to T-Mobile, I start receiving modem crashes, 5-6 crashes per day. Crashes happen while the phone is idling. I just come and see the crash dump.
It says:
Qualcomm CrashDump Mode
------
Code:
ssr:return:MPSS:qmi_oem_svc.c:1310:oem:go_to_error_fata
SDX5x esoc0
modem crash
mdm_get_restart_reason
I can restart after it using Vol Up + Power button, and it loads fine.
I found the following commands to reset modem data partitions:
Code:
fastboot erase modemst1
fastboot erase modemst2
Is it safe to wipe modemst1/2 partitions for 7T Pro? I know that some devices keep their IMEI (for 2nd SIM for example) inside those partitions.
Is it a known problem? Is there another solution for that? Are there other modems I can flash and hope they won't crash?
Thank you so much.
Build number: 11.0.1.7.HD61CB,
Model: HD1925
Baseband version: HI.2.0.c9-00145-SDX55_RMTEFS_PACK-1.367946.27
Kernel version: 4.14.190-perf+
Android security update: 2022-02-01

Disabled 5G, it didn't help. Disabled Wifi calling - no crashes for the last 24h.

Make sure to backup and then erase the two modem data partitions as well. You can find the fastboot commands in the XML of the firmware packages.
Without behaviour might be not what you are looking for...
I worked for me thanks
Modem file for dual sim
Can anyone please share modem file for dual sim model as I've accidentally selected radio band as USA and hence won't get the network in sim slot 1. Also, if possible, please share link to a step by step tutorial as I'm a novice. Also plz tell me if flashing is possible without using a pc and will the warranty of the phone get void. A prompt response will be highly appreciated.
Thanks
I think Flashify can flash without an external device BUT having the OS (Android) running with all the options for locks and alarms would scare me.
I do _think_ that flashing original Motorola signed binaries will not void anything, to be more precise: With a locked bootloader such procedure should be impossible.
Before you flash a baseband (modem; for which we'd need your current version - see "my phone"), I would recommend just erasing modem setttings. I suspect this is where the modem config is permanently stored so erasing it should set this to default.
fastboot erase modemst1
fastboot erase modemst2
I would assume that after you boot, your device crashes once - so it does for me after flashing the modem. Happens when I make the first call. So just try calling your mailbox or something.
Again, I can't and I won't gurantee anything. You warranty is void!
Here's the version of baseband my phone has got.
tinypic.com/r/2ntb49c/9
I strongly suggest you try the fix above before going after this. This reflashes your modem which might be unnecessary.
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
The modem files are in the download, the ones you are looking for are in:

Thanks a lot, erasing the modems did it for me.
Many thanks mate.
Great. You can hit the "Thanks" button if you appreciate it.
I could fix my phone by erasing modems, after doing that I performed a factory reset, but now I've another problem. Installing apk files takes longer time than it would take earlier, does it have to do anything with the problem I was facing earlier?
That does not make sense - it just takes longer on the Moto X; I've experienced the same...
But it was pretty fast before doing the reset, I tried further resets, both hardware as well as software, but to no avail. The installation process is very slow, it took Facebook app atleast 5 minutes to install from apk file. Even installs from market take time and it's annoying.
See my other thread just posted. Assume this is because installs need to be converted from Dalvik to ART.
I know it was a lot faster under e.g. 4.4.2. But you sure it was also for any device with 5+?
I used this device for 2 days before messing up with radio band, i didn't face this problem during those 2 days and i used a Moto g3 for three months, didn't face this problem with that either. And it's dead slow, like currently my fb app is updating in background, it already has taken 12 minutes and is asking for another 3 minutes for a 45mb update.
I guess getting this phone replaced is the safest bet for me, as i have witnessed one more problem. When i keep the phone aside and pick it up after some time i see some strange coloured vertical lines on display at the right with rest of the screen being black. It gets right only when i lock and unlock the screen with power key. Any idea what it could be?
Hardware issue?! I would try and see what happens when you reflash it to full factory but that's of course only what I would do.

Tried to Flash stock, now no wifi or Sim

The ROM I was using wasn't working so I decided to flash stock to my phone again. Now when it boots it has no wifi and doesn't recognise the (single sim model) Sim Card.
It also reboots periodically.
I can't find a fix for this, but I think it might be because I flashed the Europe Stock while my phone is from Vodafone australia.
Restore your nandroid backup or flash appropriate firmware for your region.

What region would the Australian Vodafone version be?
I don't know that..Try Asian firmware..if nothing works restore nandroid backup you'll find those here on other threads.
Flashed the latest EU stock I could find and it does boot. About 80% of the time it boots it doesn't connect to wifi or mobile and reboots. Looked at it in log cat and can't find anything I think could cause it to not work.
When it does work there is no mobile data even though I set up the APN as Vodafone instructed on Vodafone's site
Was looking around in logcat looking for why 3g isn't working found this

Reset it and and booted with no wifi, ran logcat and towards the end got this chunk.
Have rebooted about 20 times and gotten no boots with wifi or sim
Found out the australian version is the EU firmware from the Vodafone website
When you flashing the stock firmware are you flashing the modems and radios correctly?
Try this thread
http://forum.xda-developers.com/moto-x-play/general/how-to-flash-stock-marshmallow-firmware-t3277657
I'm fairly sure that I'm flashing the modems and radios correctly, but I will reflash using this guide anyway.
Is there a way to flash those two without reseting the phone?
Okay reflashed the phone using the commands from the Forum post. In the select wifi network menu it has no wifi and MAC 02:00:00:00:00:00 and occasinonally says "Turning Wi-Fi on..." with nothing much happening
Okay got it past the start scren and basically got it back to square one with still no 3g and it only boots with Wifi and Sim one 3rd of the time
Tried just flashing the Modem with
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase customize
fastboot erase clogo

Cm13 is stable now. I haven't used it..try Cm13 or resurrection remix.
Installed CM-13, wifi works but no Sim is detected (My Phone is Single Sim btw)
Okay in CM13 Sim started working but no 3g

Motorola G4 Play - X1607 Consumer Cellular edition - Fix SIM Lock (6/2018 SW update)

I originally bought an X1607 because it was SIM unlocked (or at least wasn't enforced) in 1/2017.
As of an Android update to 7.1.1 in 6/2018, the newest radio firmware either enables SIM locking to Consumer Cellular SIM cards only, or at least enforces it if previously enabled.
My phone essentially became a brick, as I wasn't able to use it as a phone or an LTE device.
First I tried to just buy an unlock code from eBay. Nobody at the time of this posting was able to generate the unlock code. Consumer Cellular was of NO HELP at all, I'd rather bang my head against a wall than talk to them again.
Luckily for me, BOTH of my parents also had this phone, so I had a few phones to work with and try to get it working.
NOTE: Do NOT just unlock the bootloader and install Lineage, that will not make it work.
It took some doing, but this is how I fixed the issue. It works with a stock phone with a locked bootloader.
1) Download the official image for "harpia" at the link. [mirrors.lolinet.com/firmware/moto/harpia/official/]
2) I used the "Consumer Cellular" version, but I hope that it will work with the others. The "CCAWS" version was the one that I used. (NOTE: If this is not in fact the "Consumer Cellular" version, it did work with my phone version).
3) Copy the following 2 files out of this zip file.
NON-HLOS.bin
fsg fsg.mbn
4) Perform the following commands from your command line.
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
5) Reboot, and you should have it working now.
6) Turn off all Automatic Updates, you don't want to do this again.
Please let me know if you have any issues and I'll do my best to help you out.
Great timing, a friend just ran into this issue and I will now be able to help them out...hopefully
Thx

If you have any issues, PM me and if I am needing to add or improve the OP, I'll edit it in there.
Worked great, thx.
Have you tried flashing other carrier firmware, like maybe the unlocked version? Or do you have to unlock bootloader to do that?

You're welcome. Glad to have helped.
Good question on flashing to another carrier.
Just took a look, and didn't see anything that is obviously looking like it is T-Mobile. They might not even have a G4 Play version. I was just irked that it had worked for so long that they just now decided to lock it, and then were completely unwilling to unlock it now that I'm well outside of the return window.
Thanks for posting the guide! Worked great!
Might want to post this to the Moto G4 Play forum, because this forum is for the OG Moto G.
But otherwise, nice guide!
Many Thanks
I haven't tried this unlock yet but regardless...A big thankyou for your listing
did not work for me

Hello, I have two Consumer cellular in android 6.0.1 and followed the steps you provided, downloaded the ccaws version but it keeps on prompting the unlock code, I wonder why you used CCAWS if phone is consumer cellular and that is the firmware presumed to be the carriers, it wouldn't make sense to use the same model's modem to unlock it. Any other suggestions?
Goodnight. update the phone that was unlocked did not request sim code. Now on reboot I am left with network blocking. What would be the solution?

Bunch of XT1962-1 questions / Can MVNOs see if you are rooted?

So I have a ton of questions, and maybe some answers for someone having similar issues. I *have* RTFMs, but I am not positive things are still the same in the real world. Maybe they are, and I am just doing something wrong. I have been a paint by numbers copy/paste Android person for years, and I work with unix (mostly AIX7 these days) in the real world, so I have some familiarity with technology and unix in general, but Linux and Android are very different animals. I am not a complete clown, but it is probably safest to treat me as one when it comes to Android phones, and the Motorola ecosystem is pretty much brand new to me.
I have a rooted, unlocked bootloader Moto G7, a XT1962-1. The file I happen to be flashing to recover is named: river-user 9 PPO29.114-134 fee207 release-keysM632_26.100.01.120.01R. I am using RSDLite 6.2.4 to flash it.
I have Total Wireless, and after uninstalling/reinstalling Magisk, I cannot keep a cell signal. I tried a trial SIM from Mint Mobile, and it also would not work. The Total Wireless SIM, which I had been using without issue for months, keeps getting a full, strong signal, then completely dropping to zero, in cycles that last about 10 seconds. Connect, great signal, nothing, great signal, nothing etc. I am stationary in a location that ordinarily has excellent service, so this isn't a signal issue. The indicator shows SIM Locked/No Signal/5 bars back and forth, in those ~10 second intervals. Very f'ing frustrating, to say the least. Total Wireless support is a joke, they couldn't help at all. (I spoke to someone for literally several hours, he eventually tansferred me to a supervisor. I had told the first guy "My signal is FLUCTUATING" - when the "supervisor" got on the line, she said "I understand your signal has been FLATULATING" - Correcting her English would have been like telling Costello that "Who" isn't a proper noun, so my gassy phone and I let it...go). They told me my SIM was bad, so I ordered another and it just flat out wouldn't activate at all. The Mint Mobile SIM just wouldn't get a signal at all, and when I called their (terrible) support, they told me the phone was locked (it isn't). So I restored the phone to full stock, relocked the bootloader and tried again, and both SIMs work fine, perfect signal. As soon as I start flashing or tinkering with anything, the cell signal starts going up and down again. I have found that a fresh flash from RSDLite will get the SIM to connect and behave properly, relocking the phone bootloader is not necessary.
What I have been doing is flash fresh with RSDLite, then push TWRP to RAM Recovery and installing, then boot and patch a boot.img with Magisk Manager, then fastboot install that image to install Magisk and get root. Sometimes this works, sometimes it bootloops.
So I have been tinkering for the past week trying to get this phone back up and running properly with root, and trying to track down exactly what breaks it. So this brings me to a short list of questions that would really, really help a lot if anyone knows the answers and would be willing to take a moment to post. In no particular order:
Can MVNOs detect root or unlocked bootloader? If so, is there a way to hide? I have tried many different ways, so far to no avail, after I start modding, I lose cellular. What apps should be hidden to avoid this?
When you do a TWRP Restore from a backup, what boxes do you check (What partitions do you recover)? When I restore an old TWRP backup, I hit a bootloop every time. Multiple backups do this.
What is the best way to install Magisk? Do you still patch a boot.img from within Magisk Manager? Can the patched boot.img be installed using Install Image from within TWRP?
I did a SHA512 of the magisk_patched.img file between two different installs, and it is different. Unless I screwed up and used 19.3 instead of 19.4, it should be the same, unless there is a random number involved in each installation. Is there?
What is the newest version of TWRP for river? I am running twrp-3.3.1-0-river.img. I *assume* this is the newest for river, but ASSume, right?
Thanks for any thoughts or guidance, I am kinda at wit's end. If this were my only phone, I'd be hosed. It is, however, my current favorite, and I'd love to get it chugging along again.
Ah, firstly, I was applying an old firmware. XT1962-1_RIVER_RETUS_9.0_PPOS29.114-134-2_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml is the August update. That doesn't fix my problem, but it helps...

I have had the cellular signal fluctuation problem several times. The error messages are very deceiving and point to a bad SIM card. I had the signal fluctuation problem a few days ago. My device is a XT1962-1 (river) running PPOS29.114-134-2, my service provider is Google Fi. My device is bootloader unlocked and rooted with Magisk. TWRP is installed.
If you look at the fastboot commands in the flashfile.xml file included with Motorola ROM you will see two commands to erase the modemst1 and modemst2 partitions.
fastboot erase modemst1
fastboot erase modemst2
I booted my device to bootloader mode, connected with USB to my PC and in a command prompt window I executed these two commands. I rebooted my device and my cellular signal was strong and stable.
You can google "fastboot erase modemst1" and find many references to the exact issues you are having. I have not been able to determine why my device does this, but I now know the steps to fix it.
Good luck.

Thank you so much for responding, I will try that. I have been trying every different combination of things, rooting and installing TWRP in different ways and different orders, and with different versions - so many permutations. I was almost at the point of noting what compass point I was facing while flashing things, wearing different colored shirts, and maybe pressing the Enter key with my left hand instead of right.
I do have it working now, but as soon as it reboots, it will likely go back to fluctuating. At that point the first thing I will try is "fastboot erase modemst1".
There are some posts about people booting BP Tools mode and fixing this issue, but that didn't work for me. There were apparently some changes made in response to CVE-2016-10277 that may have broken that fix with Broadband Processing mode (I *think* that is what BP stands for...)
Anyway thanks mate, i am grateful, and will post what happens. The Location spoof Search option in xPrivacylua Pro breaks sometimes and requires a reboot to fix, and mine just did that, so a reboot is in the near future.

For posterity, I wanted to follow up that this worked! Thank you again, this is just awesome!!
The Mobile Data button actually still says No Internet like it has since this issue began, but I have a steady four bars, and everything works perfectly, so the indicator is just wrong.
This is why I love XDA - people like you who take a moment out of your day to share your knowledge with those of us who bit off more than we could chew. Thanks again mate!

Kernel Crash - Modem Crash

So teach me about modem modemst1 and modemst2 partitions and kernel panic -modem crashes. I have a H910 and recently dirty santa'd and unlocked. I have tried a handful of roms and a couple of kernels but have been unable to pinpoint the occasional modem crashes.
I have been fastboot flashing different combinations of modem files with different sets of modemst1 and modemst2 files over trying to find the best setup. I have an "elevator test" where I take my phone in the elevator to the sub basement parking area of our apartment. Some combinations crash immediately and others not so much. Some have no coverage in the basement and only 2 bars in the house. Others seem to have great coverage and even some coverage in the basement.
I built my own Oreo modem based on #Koodz work here and using my OEM files from my Nougat LGUP dump (before I started everything). I even built an Android Q based modem from the Lineage 17.1 base modem using the same steps. I have the modem and modemst1/2 files from stock Nougat, Alpha Omega Oreo, Alpha Omega Nougat and Lineage 17.1 So I have been trialing different combinations of modem files with modemst1/2 sets trying to find best coverage without crashing. But basically it seems that everything seems to eventually crash.
So is there another thing in this mix? Does the kernel play a part in this? I ran this thing on stock Nougat for years without a single crash? All the different ROM's seem to also crash. Resolution Remix crashed all the time - but it was early on and I did no other modem testing at that point.
Any tips on what to test or how to further diagnose would be appreciated.
Thanks
Hello , same problem, do yopu resolve it ?
Wow - That was May and I got no help. I just kept trying different combos.
I can't really say it was solved. I never got to where I wanted to go - Lineage working.
I am running AlphaOmega Oreo and I think - I am using the Oreo Modemst1 and 2 files from the ROM along with my stock modem file from my LGUP backup of stock ATT Nougat.
But - if you do something like this you have to test everything:
GPS lock works
Fingerprint works
No crash when moving from 4g coverage to 3g.
No crash when moving from to no service.
If you don't test all of those - it might crash when you least expect it.
Sorry that I can't be more help. Look at my link above if you need more help on installing the Modem files etc.
Good Luck!
So are you saying that Lineage kept crashing but the AlphaOmega Oreo rom isn't with your current kernel and modem configuration?
Cheers
