MDOB rom messed up S4 (full wipe doesn't wipe everything?)

System Specs: Galaxy S4 Canadian i337m OTA 4.3 (jfltecan), carrier is Bell, stock Samsung firmware, stock kernel (use wicked rom 9.1 sometimes too)
WARNING:
lot's of reading so go grab a coffee and have a cigarette before you sit down to read this, you'll probly be here for awhile
The rom/fix in question: MDOB rom/i337m fix - here's a link to both.
http://forum.xda-developers.com/showthread.php?t=2280556
first off i'd like to mention this phone was 100% perfect on stock Samsung rom 4.2.2 using Ktoonsez KT-SGS4 kernel for many months, until the day I installed this dreaded MDOB 4.2.2 rom and the "fix" that came with it
everything went bad on me back while I was running 4.2.2 stock unlocked boot loader and could never get it back to normal so this isn't a issue caused by 4.3 knox or 4.3 itself that i'm currently using. (i'm stuck on 4.3 roms but had this issue way before 4.3 existed)
i'm having an extreme amount of issues AFTER installing the MDOB rom, even after changing rom back to stock (flashed back to stock rom with ktoonsez kernel which is what I was using before I installed MDOB rom and phone has been royaly screwed ever since that day) more specifically I think it happened from the "i337M fix" that's included with the rom, either way after installing this rom I've never been able to get my phone back to normal.
everything runs fine except until I install a custom kernel (Ktoonsez KT-SGS4 kernel) then all hell breaks loose.
I don't blame the kernels or my current rom since I've ran this before for many months until the day i installed MDOB rom on my phone my phone was a dream machine.
issues since this rom has been installed include:
Issues:
A. RANDOM SLEEPS OF DEATH (phone shuts off or freezes)
B. random freezing while trying to turn on phone or enter recovery
C. some kernels won't work proper (specifically ktoonsez KT-SGS4 kernel) example gpu stuck at max while idle and downclocking when screen is touched with this kernel
D. wifi won't work with custom kernel on stock 4.3 rom without build prop edit to ro.securestorage.support, although it should
E. weak wifi and mobile signals
F. bad battery life
G. bad call quality
H. More that I can't remember off the top of my head
here's my flashing process, in attempts to remove as much as possible:
I know a few of these steps are probly pointless but hey can't blame me for trying.
step 1. enable usb debugging & unknown sources
step 2. install root & recovery
step 3. fresh boot phone let files settle so they can save (5mins or more) then plug into computer while turned on and delete everything
step 4. reboot into TWRP recovery (version 2.6.3.1) and clear everything, full advanced wipe, factory reset, format data than clear cache/dalvik afterwards just to be sure
step 5. remove SD card plug into computer and format to make sure there's nothing
step 6. install rom
step 7. (sometimes) clear cache/dalvik/permissions after rom install, although fix permissions seems to break my permissions rather than fix them or maby my permissions just break during flashing and I just can't fix them (haven't tested enough to be 100% sure)
i'm SOOO temped to try a full nand erase since i noticed there ARE still lot's files on my phone directory even after wiping, but i know that isn't a good idea;(
once stock kernel is back on my phone these issues are all gone.
Ktoonsez says it's not his kernel (used to work before, so i have no reason not to believe him), he says it's the rom well i'm on 100% stock Samsung rom (exception of kernel) and the rom was built to act the way it does so you can't really blame the rom so who do i blame??
until i went to go try wicked rom and flash back to stock I didn't realize these things were still on here, but now they emerge! wicked rom was giving me some (unrealated?) issue so i decided ima go back to stock so i flashed stock rom via odin (pc) and right away i noticed the 4G symbol, Samsung wallet, desktop not setup proper (no shortcuts) this ONLY happens when switching from wicked rom to stock rom on the first flash, i flash again everything looks how it should, and in order to get it to do this again i have to flash back to wicked rom and flash stock rom again and BAM it happens.
i knew my issue started on the same day that i installed this MDOB rom but after doing a full wipe and MANY "fresh" stock rom installs later i stopped questioning the rom and just lived with a crap phone that reboots itself all the time and has bad battery life, AS SOON AS I SEEN THE SAMSUNG WALLET bam it hit me like a truck, IT WAS THE MDOB ROM INSTALL.
UNLESS stock Samsung rom comes with wallet preinstalled and hidden on stock/wicked roms than the ONLY other way it coulda got on my phone is from the MDOB rom.
I can wipe/delete/factory reset/flash with twrp & odin on pc all I want, my roms are still messed up after FRESH installs. I believe there is still left over files from this rom/fix, I didn't think there would be anything until I noticed when i'm flashing from wicked rom back to complete stock rom using odin on pc I experience things from MDOB rom (while It should be 100% stock after odin (pc) flash, but it's not)
after the first flash from going from wicked rom back to stock I always experience the following "bug" i'll call it a bug since these things ALL HAPPEN AT THE SAME TIME: once I flash AGAIN all these symptoms go away until I go back to wicked rom and flash back to stock rom than right there after this first flash going from wicked rom BACK TO stock ALL these symptoms come back until I flash stock firmware AGAIN, a second time (even though I just flashed it)
Symptoms:
1. Samsung wallet appears in my apps (this was only EVER on my phone once, when I had the MDOB rom on my phone), this thing shoulda never somehow appeared back on my phone in any way shape or form after ditching the MDOB rom, but again is comes back after the first flash going from wicked rom to stock rom.
2. I get the 4G icon from MDOB rom (not the LTE icon I SHOULD have while on stock, when on wicked rom I have a little LTE icon with a tiny 4G above it, the only time I've ever had just a 4G icon (without LTE) like this is when I had MDOB rom on my phone (which is the only other rom I've run other than wicked rom and stock rom).
3. this icon ONLY shows up after the FIRST flash from wicked rom back to stock, once I install stock AGAIN than it returns to it's normal LTE icon.
4. now i'm not just *****in about an icon here, this is just a part of my problem (indicator if you will), when my rom is "bugged" after first install from wicked rom to stock rom my wifi works normal how It used too. but once corrected (flashing again) AND using custom kernel on STOCK firmware it breaks my wifi 100% broken until I use this little build prop edit fix, set ro.securestorage.support = true to false, bam wifi now working but the rest of my problems are still there (wifi used to work 100% on custom kernels and everything until MDOB rom touched my phone and left this "bug" behind)
5. when this 4G icon appears after this "first" flash back from wicked rom to stock rom I also experience something else, my wifi button works during first boot setup and auto enables itself and I have no issues with my wifi connecting (as soon as I see this toggle on I already know once my phone locks onto the network it's gonna give me a 4G icon and not an LTE icon like it should and sure as shiznit it does, as soon as I get my icon back to how it's supposed to be (LTE icon) all of a sudden wifi won't auto connect on a first boot anymore, never, 100% never. (back before installing MDOB rom I used to auto connect 100% of the time on first boot) like it does now only when it's "bugged" out.
6. apps are missing, when this "bug" appears there's no app shortcuts on the desktop of my phone by default after fresh flash like there should be, sometimes they appear on first flash once in awhile (some apps might not even be installed? or just shortcuts missing, have yet to verify)
7. it feels like the phone flashes way too fast (second flash takes longer, I think?) and more/all? apps get installed on second flash, and Samsung wallet get's REMOVED (how'd it even get there? other than bein left behind from MDOB rom, same with the 4G icon, that icon isn't in either of the two roms I use so how does it get there? and ONLY at the same time the wallet magically appears and the rest of this stuff)
8. when this 4G icon appears my phone seems to be great except for the fact that I know my rom didn't install properly since i'm still missing apps ect, once I flash again, apps appear, Samsung wallet DISappears, 4G icon gets replaced with LTE icon and everything is A-OK until custom kernel is installed, remember this is NOT the kernels fault as it ran 100% perfect for many months ON THIS PHONE until the day this MDOB rom was installed, and it's had these issues ever since.
some of the things I've tried:
- Countless wipes, including full advanced wipe, restore to factory, data wipes
- Ton's of fresh installs of BOTH versions of 4.2.2 - now doing same with 4.3 and wicked rom 9.1
- Tried wiping using TWRP and odin mobile (flashed mobile odin via TWRP, it works incase anyone didn't know)
- Tried flashing roms using odin (pc) v1.85, v3.07, v3.09
- Downloaded new copys of roms from new sources to make sure my roms weren't corrupted in anyway
i'll hopefully edit this post and get some pics up soon and simplify my text to help you guys better understand my situation and i'll also add a list of things I've tried to fix this problem when i have time.
any thought would really be welcome, there's sooo many of us s4 users with random sleeps of death, i'm sure if we could fix this it would help out a lot of S4 users.
thanks, dustin

Have you tried to flash the stock firmware in Odin. You can get it off the Samsung Updates site.
The guy who puts MDOB together generally makes great rom's. If everyone had the same issues then no one would use it... you really could have gotten a bad download, user error somewhere or one of many other problems.
With apps' just "appearing" are you certain once you log into your google account that it not set up to automatically start downloading apps ?

don't get me wrong, i'm sure it's a great rom but my battery drain was worse than stock so I went back to stock, I REALLY appreciate his hard work towards our community. I just dislike what it possibly did to my phone is all.
and I don't have issues with the MDOB rom itself, it's AFTER that rom has been on my phone EVERY other rom ever since then now has issues in some way shape or form, no matter what I do.
if it's user error I put down the steps on how I flash in OP, I dunno what's going wrong
i'm gathering screenshot's to better show my situation.
I am 100% positive GAPPS is NOT installing anything after rom installs (I don't connect to wifi until after setup is done spacificlly to prevent this from happening, my rom just flashes this way (only on first flash from wicked rom going to stock rom) once I flash again a second time my symptoms part goes away and I get the issues part of my OP
if i'm on wicked rom and flash to stock = symptoms listed above
if i'm on stock rom and flash to stock = issues listed above
I can replicate this problem all day long.

I've flashed his rom on and off. Never had the issue. The rom doesn't invade anything a full wipe wouldn't cure. If it doesn't full wipe then it's the recovery. It helps once in awhile if you Odin back to stock or even copy your sdcard contents and format your sdcard to make it fresh. read up on it first.

Also I recommend doing 9 wipes when swapping roms. It sound ridiculous I know but I do it and have never had issues.

Just odin back to stock and set if that clears things up. It should solve any odd problems. The thing with flashing rom's is that someone's issues cannot always be replicated.
Going back to Odined stock will take it back to factory stock then do a factory reset in stock 3e recovery and you should be fine

Problems CM based roms

Hi I got problems with my lux on every cm based rom. On every cm rom I get no reception of my carrier. I don't know if it's a device tree issue or just apn trouble. Since there are no aosp roms, I'm a little hung up. Stock rom works fine. I own the xt1562 operating on German carrier o2. Sometimes I get a few seconds of reception on cm roms, but it's leading just to no signal after a few seconds again. I nearly tired everything, flashed a different firmware etc. When I've flashed a rom I get the information that no sim card was found. After I restart the device he's asking for a pin. Also tried another sim card with the same result. Really could need some help.

flash the original fimrware from ur carrier or region
flash twrp
install cm and see if works
if not,flash only the radio modem from original firmware

Already did. Didn't work. Flashed the new cm12.1 from h2o64. This one is working.

I have the exact same problem with my XT1562 I bought from Germany through Moto Maker.
I installed h2o64's CM build from 10-10 after a full wipe (everything except internal data), and never got any proper signal. I tried squid2's CM build 10-12 as well, to no avail. Installing the XT1562 EU stock firmware following the linked explanation in the stock firmwares thread I had good, working signal, but then installing h2o64's CM build 10-14 with a factory reset rather than a full wipe resulted in the same issues described in this thread again.
I've read about these issues in different threads, mostly resolved somehow by installing the stock firmware, sometimes by selecting LTE as the preferred network type. I've tried these suggestions, but haven't had any success, and I don't know how to proceed.
Did I install the right stock firmware? (I would think so as it worked while it was installed.)
Did I forget to do something (like wipe, fix permissions, reboot the phone three times, howl at the moon,...)?
I use OpenGApps rather than tkruzze's since they're available in x64 as well so I can use them on all my devices. But that surely can't be it?
I'm at a complete loss at the moment, which is rather frustrating. Can anyone provide any help?
Gesendet von meinem Nexus 9 mit Hilfe von XDA Forums Pro.

I managed to install h2o64's CM build 10-14 and getting proper signal now.
I flashed the RETASIA firmware from XMoDuLeSx's Official stock firmwares added for xt1562,xt1563 thread following the instructions linked in the first post, and then after a wipe of system, data, cache, dalvik-cache I installed [ROM][lux][5.1.1] Cyanogenmod 12.1 - 2015-10-14 [UNIFIED].
Keep in mind that I have ordered my Moto X Play from Germany, so it shouldn't require a RETASIA firmware. I'm not advising to install this, as it was nothing but a shot in the dark that surprisingly didn't brick my phone. Still, I wanted to share that I got it working after all, simply to follow up my previous post properly. Should the signal break again, I'll update this thread; if I haven't, assume that it's still working.
Either way, though: If you decide to go down this road and install a firmware that isn't right for your phone and brick it, don't come to me. I'm advising against doing this.

Seems i'm having the same issue...
I did all the wipes and clean installs but I can't connect to my carrier.
Although my phone only supports one sim card, settings shows two. The first one is the one i'm using and it is displayed correctly. The quick settings tile though tells me that there is no sim card inserted.
I came from stock, unlocked, flashed TWRP from squid2's kernel page, rooted, flashed CM(squid2), kernel(squid2) and OpenGApps.
Did I do something wrong?
Is there any news on how to fix this problem or do I have to try again and again an hope to hit the spot?

You need two more posts before you can post this in the CM thread from squid2. Squid2 is always fast with bugfixes. So make 2 other post and then explain your problem to him.

Thanks for your reply!
I will do that
Meanwhile I managed to get a connection to my carrier by flashing h2o64's CM build 10-14 and then squid2's on top without wiping anything...

OP2 kernel problems, considering H2OS?

Hi all, I am new here. I was referred by a friend who knows more about this than I do. I think I understand how to get fastboot and TWRP, so that is taken care of already. Now the problem with my OP2 running OxygenOS latest version, everything stock, is that it freezes up after unlocking, and the whole phone is just terribly throttled at this slow speed for a long time. All inputs are extremely delayed, and touchscreen is nearly unusable after the lag begins. There are so far two temporary fixes I found: 1) reboot phone 2)wait it out/keep unlocking until it doesn't lag. I also have been unable to make a copy of my internal storage via USB, as it gives unspecified error during copying. And lastly, the screen dims on its own sometimes at random while anything related to auto-brightness should be off. Fortunately, I was able to make a hard copy of my internal storage thru some wifi file manager apps. Now my friend pointed out that my phone's issues could be related to a bad kernel. To remedy this, he told me it would be good to flash a new kernel onto my phone. I considered changing roms to CM, but apparently a lot of functionality is lost when doing this. He told me that I could retain Oxygen OS while flashing a new kernel, but I am not sure how to do this. I came across a post in the android dev section regarding hydrogen os, and I read that it performs better than Oxygen OS, but has minor issues of its own. I am interested in flashing this rom/kernel (I am not sure which is which). Here is the link in that section of the forum I found http://forum.xda-developers.com/oneplus-2/development/rom-h2os-hydrogen-os-ota-clean-stable-t3195636. I see it says that it is working on Indian OP2, and running stock rom and stock kernel. Does this mean that my north american OP2 won't be able to get this rom? Also if it is the stock kernel, does that mean it is the same kernel as the one currently installed on my phone? Anyways, if anyone knows about my phone's problems, or has a way to fix it let me hear it please. Thank you!

I had the same issue with O2. I changed kernels and the problems persisted. A also word the device and started from scratch through fastboot and the issues persisted. I ended up on hydrogen and I've never looked back. There is a flashable zip in that thread for the newest full version .11. Follow the steps wipe everything besides internal storage, flash the full v11 zip and boot the phone. After this reboot to recovery (power and volume down). Flash the gapps and super su zip if you want root. After this you should be able to add your Google account and be good to go. One thing I did was remove all Chinese apps and the stock launcher. I use trebuchet launcher from cm 12.1. Phone runs incredibly smooth now. I recently started running AK kernel as well. The oxygen version works with hydrogen. I have been averaging between 5 and 7 hours of SOT for battery with up to 8 if I'm just watching videos. Hope this helps. The ROM is a little simpler and the notifications settings are different. But you can set apps to have priority notifications and they function similar to oxygens notifications at that point. Everything is in the thread if you have any questions I'll try to help you.

No keyboard after custom ROM install (bounty!)

I just moved from Pure Nexus 7.1 to SuperXE 8.1. I think I forgot to flash vendor image but otherwise did full clean flash. ROM boots but when trying to connect to WiFi there is voice input but no keyboard. Haven't ever seen something like this before... Added vendor image and redid full/clean flash multiple times with same result. Unfortunately, activity on that ROM thread is a bit slow and I'm down without my phone so decided to ask for help here.

Adding $20 bounty for help fixing. Serious withdrawal mode without my phone. I have a backup phone but it is nearly unusable...

Solution here https://forum.xda-developers.com/showpost.php?p=76126862&postcount=263

Since you are coming from Nougat to Oreo i would suggest you first flash the full oreo factory image before flashing the oreo custom rom. Its not usually a must but solves a lot of minor problems

Need help getting LineageOS to be stable (15.1 UNOFFICIAL, hltevzw, TWRP 3.3.0)

I have an SM-N900V (Note 3, Verizon variant, hltevzw).
Detailed timeline:
- I flashed it back to firmware OB6 using Odin 3.09.
- I rooted it using ArabicToolApp.
- I used this tool to unlock the bootloader
- I installed a build of LineageOS 14.1 for hlte
- It didn't recognize the SIM so I did a dirty flash of this build of LineageOS 15.1 for hltetmo on top (hltetmo actually has different hardware than hlte, and the correct one for SM-N900V)
- Messed around with the APNs until it recognized and connected to Verizon's network. I DO have functioning SMS and LTE data, but I have not tested phone calls yet
- Messed around some with SuperSU in system- and systemless-mode. Bricked my device more times than I could count, then unbricked over and over using SuperSU's impeccable installer. Messed around with this quite a bit
- Also messed around with Xposed some. The OS is too unstable to run Xposed Installer correctly, so I uninstalled it
- Removed SuperSU, installed Magisk. Phone now passes SafetyNet
So, my phone now runs 8.1 and a Lineage build from 9 days ago. Cool. But, if I was satisfied I wouldn't be making this post. There are multiple instances of the same kind of "app freeze" - App screen freezes, sometimes it'll go completely black. Interactivity doesn't work, obviously, the app is completely frozen. Hold Back to kill doesn't work (Application Killed toast shows, but nothing happens). ANR (when it comes up) Close doesn't work. Home button works and brings me away from the app, but it's still there. Swipe away in Overview doesn't actually kill the app. Even in App Info, Force Stop doesn't work. The app is forever frozen. Tapping the icon from the launcher no longer does anything, it doesn't even bring up the app. The app is permanently crashed and inaccessible until a reboot.
Issues:
- Sometimes when booting the phone will not recognize the SIM until a reboot. As in, "No SIM" message and everything
- Sometimes it will get stuck at boot, I have foxy-boot installed, so I can see the logs. I don't remember what it was all about, if it comes up again I'll update the post
- Google Chrome sometimes crashes when trying to download a file. I've gotten my phone to self-host before, but this issue always seems to come back, and when it does Google Chrome ALWAYS crashes when trying to download a file. App Freeze
- Netflix installs and logs in but freezes at the "can't connect to service (-9)" message. App Freeze
- Certain apps like NativeScript Playground get stuck at the splash screen. App Freeze
- Xposed Installer did this when opening the Settings, whether Xposed was installed or not. App Freeze
- F-Droid also sometimes crashes, although it's somewhat arbitrary, I can't reproduce it reliably. App Freeze
I have tried reflashing the ROM, flashing Xposed uninstaller, reinstalling Magisk, none of it seems to work. I have TWRP 3.3.0 so I can do pretty much anything that doesn't involve the SD card (the SD card is probably broken in hardware, it's so read-only that Android and TWRP both can't write to it at all, but they can both read the same half-broken filesystem).
I fear that this OS is just too unstable for the phone and there's nothing I can do. I sincerely hope this is not the case.

Try other ROMs or perform a clean installation.
Make sure you are on PL1 bootloader/modem.
Currently using Resurrection Remix v5.8.5 Nougat because it was the last Android version for this device with working Bluetooth calls but if you don't use that feature you could use their Pie version as well.
RR ROMs are solid and work extremely well.
Do a clean installation via TWRP if you go this route.

I did a clean installation of RR 6.0.0 (Android 8.1) and it works a lot better than LineageOS did, with even more configuration options. I really really hate Pie and its gesture-based gimmicks (Screw you Google for copying more of Apple's bad design decisions), so I assumed Oreo would be more stable, but the ROM I installed still has crashing apps. Google Chrome still won't download most things (I've gotten it to download before), trying to change the accent color crashes the 'LineageOS Settings' app, and F-Droid is seriously messed up, but most other things are stable, including the Verizon network which required no pesky APN setup.
I'm on the OB6 bootloader/modem, is that a problem? I doubt that would be an issue, but I can always back up and reflash via Odin. The cool thing is that I installed a patch to TWRP which backs up /data/media along with everything else, after installing the custom ROM. So, really, I can do anything and be perfectly fine. There's, AFAIK, no way to ruin the phone unless something exploits the eMMC brick bug.
If there's another ROM you'd recommend me install, I'd be happy to try it out. I would really like to have a stable OS on here, where Chrome will work and download files. I'd also love Camera2 API since the phone has the chip for it (Snapdragon 800), but none of the ROMs I have support it and there's been no discussion online other than some years-old threads with no answers. I know there have been some articles online listing Note 3 as a phone that'd support Camera2 API with a software update. Would updating the bootloader/modem do anything on that front?

I would upgrade to PL1 bootloader/modem for your device. This is what I have and have had 0 issues. I'd recommend you trying the Samsung Internet browser over Google Chrome; it's much better in my opinion.
You can find the modem here:

As far as ROMs are concerned you can either try the Nougat version of RR which is what I am currently using as my daily driver with no issues at all including Bluetooth calls:

See here to check whether or not your phone has the Camera2 API capabilities; if not use OpenCamera.

Excuse me but custom ROMs don't have "the Samsung Internet browser". Additionally the modem shouldn't cause app crashes (if it does, correct me please).
I might try the Nougat ROM. Bluetooth calls don't matter to me, but stability does. I just kinda really like Oreo and all its customization options but it may be too new for this old phone from 2013. It still works as a phone though, Messages and phone calls work fine, so I may just deal with it.
I use Open Camera, and I've tried multiple Camera2 API enablers. The phone has a Qualcomm Snapdragon 800 and the necessary links (in hardware, between the camera/other things) to support Camera2, but nobody seems to have tried it. Probably because the Verizon Note 3 is really locked down, and can only be rooted on a special version of the samsung ROM, and can only be bootloader-unlocked via the eMMC brick bug... There are Magisk modules for Camera2 on Exynos-based devices, but none for the Verizon Note 3 AFAIK.

I just found out that RR 7 officially supports `hltetmo`, but RR 6 doesn't. That's kinda sad, I hate Pie, but I might try it...

I've had the SEPL stuff before, that's the one that can't be rooted. I suppose I didn't consider upgrading again after I unlocked my bootloader. I'll try SEPL1 firmware again, but with a custom ROM...

You can install the Samsung browser from the Play Store. Again, highly recommended.
As far as SEPL1 just update the modem to it; that shouldn't cause any issues but it will ensure your SIM is recognized and data works with the latest ROMs. That is one requirement you will see listed on all of these ROMs.
Not sure which one you are trying to install but here are all the Resurrection Remix versions:
Nougat:

Oreo:

Pie:
https://forum.xda-developers.com/galaxy-note-3/development/rom-resurrectionremix-v7-0-0-t3894244
If you don't care about Bluetooth audio during calls then you can safely use Oreo and Pie options.

Yeah but, data and calling worked fine on the LineageOS and RR roms, so there's no reason to update the modem.
Besides, I flashed SEPL1 6 times using Odin (multiple times by flashing, rebooting directly into download mode and flashing it once more) and it doesn't want to update. Still on OB6. On the latest (official Pie) RR rom, data worked on first boot but doesn't work anymore (I'm going to mess around with the data settings until it works), but I have no reason to believe that my phone needs a modem update to function.
I did, many times, make calls to various phone numbers and they all worked flawlessly. SEPL1 is therefore not needed if that's all it does.
And I do know about all the Resurrection Remix versions: One is Nougat from their archive, one is the Oreo version I had installed just yesterday before flashing Pie, and the other one is Pie which is now officially supported.
I am currently working on getting RR7 to work, it's only crashed a few times, and I don't even remember what those times were (I think it was using the Back button in Overview/Recents at the same time as the Overview button?)

When updating modem via Odin you have to pull the battery and don't let it reboot the phone for it to stick (disable that option in Odin) and flash it again and then reboot. If you look at the ROM threads for anything newer than Android v5 they all recommend updating to the latest bootloader & modem for your device which in this case is PL1. This can be to prevent crashes/no signal /no SIM, etc...
Are you dirty flashing these ROMs? I have never experienced any crashes with any of the RRs on my phone but I always do a clean install and make sure to also delete the "Android" folder on my SD Card via TWRP after doing the "Advanced" wipe and deleting everything listed there except for the External SD Card.

"pull the battery and don't let it reboot the phone for it to stick (disable that option in Odin) and flash it again and then reboot"
So...
- Reboot phone into Download mode
- Pull battery while in Download mode
- Flash thingy
- Reboot back into Download mode
- Flash thingy again
? That will be very difficult to do with my dodgy charging cable that doesn't like being repositioned...
I do that without pulling the battery, but I could try it with.
I'm downloading the full SEPL stock image to flash. Once that's done, I'll flash it, reflash TWRP, restore my backup, and see if the baseband has updated.
And no, never dirty flashed the ROM. Always completely wiped data, system, cache and everything. I always backup first. I currently have 3 backups: Lineage OS (before installing RR), RR6 (Oreo), and RR7 (right now before that stock image I'm going to flash).
My external SD card is nonfunctional and read-only with some trash files from the previous phone.

I flashed the stock SEPL ROM. Baseband still didn't change. Restored from backup, SIM now works. Network is detected, SMS and data both work reliably on all reboots.
I will mention that I did brick my phone by using Odin to erase the eMMC, but I fixed that from TWRP, and now everything works flawlessly. There are still some app crashes, but most things are very stable. Camera2 API still nonexistent, which is sad because I got used to it on my old phone, but I shouldn't hope for it.
