Flashing on 935F

Hi all.
I have the 935F International on it's way to me, delivering in the next day or so
By all accounts the 935F is already unlocked. To prepare, I have already downloaded Odin 3.11.1, CF's root file, TWRP twrp-3.0.2-2-hero2lte tar, and a custom ROM and bootloader/modem files.
I'm not a noob to flashing, just newish to Samsung.
What is the best way to start? Boot into stock, enable bootloader unlock on developer options, run Odin and flash TWRP, then CF's root file? Also, I want to run unencrypted - format data using advanced wipe 'yes' method?
The ROM states it sets root on installation. Do I then need to flash CF's root file?
Further, how are bootloader/modem tar files flashed? Is it as simple as selecting BL for bootloader, although I don't see anything for the modem??
Finally, what is the actual order of all this? I'm thinking: TWRP first, Format internal data second, CF root third, ROM flash from TWRP fourth, reboot to download mode from TWRP and then flash modem/bootloader last. Then reboot all together to set the phone up?
Thanks and any help is appreciated

1. Update to latest firmware
2. CF-Autoroot
3. TWRP
4. Flash no-verity-opt-encrypt.zip, wipe data.
5. Reboot recovery, mount system.
6. Wipe all except internal and external sd.
7. Flash your ROM

Thanks for the info :good:
When you say update to latest firmware this is Bootloader and Modem yes?
Steps 2 & 4 - just having done a little more research, are these outdated now?; as TWRP (latest) now fixes encryption and the ROM will inject (for a better term ) SuperSU when installing it? Or will this still need to be done irrespective of using the latest version of TWRP and ROM?
Cheers and thanks :good:

If you're not new to rooting and custom roms, pretty much all you need is to unlock OEM in Dev Options in Settings, Restart the device and hold Vol Down+Home+Power to get into Download Mode and press Up at the blue screen. Plug in your USB to your phone and run the tool on your PC.
Once Rooted, its business as usual. You don't need a guide to install TWRP, just install the Flashify app and let it do it for you, and then have no-verity-opt-encrypt.zip handy to flash. I know no-verity-opt-encrypt.zip is essential if you flash TWRP through ODIN, but not 100% sure if you should if you flashed TWRP through Flashify, I always flash no-verity-opt-encrypt.zip regardless so I unno.
Also if you find yourself in a semi-bricked situation where you can't figure out your problem, as long as you have Download Mode, you'll always have a way to get back to a working device. Samsung Smart Switch for Windows has an Emergency Mode that will revert your device back to Factory Conditions.

I've been doing things this way since day 1 with no problems. My advice would be to do it the same way. I can assure you a solid install ;]
Yes, firmware is bootloader & modem. Great thread for this is here http://forum.xda-developers.com/s7-edge/how-to/official-stock-firmware-update-odin-t3335065

WiFI doesnt work Show 02:00:00:00:00:00 mac address.

Hello to everybody, the wifi phone of my OP5 woked very well. One day I flashed one ROM, I dont remember what and broked the wifi, now show the typical broken mac address, I saw all the post even fixing nexus wifi phone but didnt work. I lnow that I need to upgrade to Oreo, now Im in Nougat, but the problem is when I flash the oreo stock rom the phone get a bootloop, I tryied everything so I need to forget upgrade. How can resolve this problem. I updated no stock ROM oreo like aiscp but the wifi not repair. I dont know what do. I tried with QPST QXSM but nothing I can repair my phone. Any help?. I tried too modificating all the files about wifi, wifi.bin (I dont remember the names) and didnt worked

If you are using TWRP make sure to update to latest codeworks version and in the wipe section select format data. This is necessary when moving from Nougat to Oreo on the OP5 if you are using a custom recovery. That will erase everything on your phone except TWRP. Plug your phone into a computer and it will show up like a USB drive. Copy and paste the Oreo ROM zip for stock OOS onto your phone. If you want to be rooted also copy the latest Magisk zip. Flash OOS zip within TWRP. If you boot into the system after that you will be 100% stock including recovery. If you want to be rooted and keep TWRP flash Magisk zip as well before booting into system. Given your circumstance I would highly recommend going 100% stock and making sure everything is working right again. You can always install TWRP and root again later.

i remember how i flashed blu spark kernel for custom rom, when i was at stock oos and get this broken wifi. try to look at that

Oreo 8.1 Update T585XXU4CRJ8 problems

Hello all
I installed the latest T585XXU4CRJ8 Oreo 8.1 update over Nougat 7 on the SM-T585. (BTU / UK)
Everything went well using Odin and the Oreo stock rom from the Updato website.
Cleared the cache and factory reset from recovery mode as normal practice. Booted up ok.
The problem is the device doesn't recognise the network sim card anymore (worked perfectly on Marshmallow & Nougat).
I've tried factory reset a few times, no difference.
Removed and reinserted the sim, even tried another sim.
Having checked 'about tablet > software details' , carrier is unknown and the IMEI has dissapeared !
I've tried to reinstall Nougat 7 and Marshmallow 6 back on the SM-T585 and Odin fails every time.
Tried 2 computers and 3 different usb cables.
Even trying to reinstall Oreo 8.1 again Odin fails!
Theres no frp lock activated, and the oem unlock tab is checked, usb debugging enabled too.
I've read somewhere Samsung have done something to Oreos BootLoader file to stop people downgrading back to earlier software.
I know its early days, but if anyone can offer any solutions, it'd be appreciated.:good:
How to change the BL file version, so i can reinstall earlier stock roms back?
The Oreo update seems more hassle than its worth and I didnt expect the sim card to be unrecognised once updated, let alone being faced with the puzzle of how to downgrade the software.
Thanks for reading. :good:

I think the problem was I used all four files (AP, BL,CP & CSC) from the Netherlands rom and that's whats screwed the device up!
As in no SIM card acknowledgement. I ran the IMEI number off the rear casing through a blacklist checking site and it came back clean.
After many attempts trying every Odin program variant possible and even tried mixing and matching files from different stock roms ( MM 6.0.1 , N7 and Oreo 8.1). To try and get the network carrier file installed, Odin refused to install anything.

https://download.chainfire.eu/1069/CF-Root/CF-Auto-Root/CF-Auto-Root-gtaxllte-gtaxlltexx-smt585.zip
https://twrp.me/samsung/samsunggalaxytaba101wifi2016.html
Tried the above routes to root to no avail, but Magisk worked by patching the boot.img file (which worked ok). Then tried Odin to install TWRP recovery, again from the site above, nothing but blue and fuzzy lines on the boot screen. The device wouldn't boot into the OS, had to go straight to download mode. Prior to that, I even installed the TWRP manager apk and connected to wifi to flash the TWRP.img from inside the OS environment and the same happened again with all variants of TWRP! Wouldn't boot, properly, no screen visuals, but lines......
Surely someone else on here has the same device (BTU UK) SM T585 that has a working TWRP recovery?
After many hours, I couldn't get Odin to play ball , so the only option left was to try the route of root, twrp recovery then installing a custom rom from twrp.
(https://forum.xda-developers.com/ga...-ultra-lean-rom-galaxy-tab-10-1-2016-t3467942)
But it's a no go as TWRP wouldn't install properly, I'm totally miffed by the damage the software has done.
Surely just reflashing the CP file should have reinstated the network facility, but it hasn't.
The last resort is for me to wait until Samsung actually release the UK version of Oreo 8.1 and see if I can get the sim card working again.
Moral of the story is wait until a UK version of the update is released, and even then you have to question is it worth it, if Samsung are making bootloader files so no downgrades are possible, nor allowing any modifications.
Hopefully this info may help others out who are thinking of upgrading or having similar issues.

I had the same problem, went from Lineage 14.1 to Oreo stock rom (the flashable one you can find on this site, i flashed also the Bootloader/modem file in the thread). No imei, no baseband. Returned back to lineage and got back imei and baseband, but after my screen was going to sleep (after the regular 1 min) I had only black screen and vertical red lines. I flashed then Resurrection Remix 6.2, Lineage 15, Lineage 16, always the same problem. Then I used Odin and the original firmware of Nougat from SamMobile, at the first attempt i flashed only the AP file. I turned to have the same problem, but this time the lines were white. I flashed all the 4 files again with Odin, problem solved and back to Lineage 14.1 (the only custom rom were everything works)

What version of TWRP have you installed for the T585 and from what site?
Also what root method did you use?
I have tried all available and all seem corrupt i.e don't install properly, no proper boot up with onscreen options. Just fuzzy lines.
Again root i've tried many, but don't work with this Oreo 8.1., even Magisk is problematic.
I think its pretty sad of Samsung sending out poor quality updates for us to use. Their heading the same way as Apple and the way they control customers.
If I could go back to a custom MM or Nougat, I would. But TWRP / ROOT are an issue. i.e no TWRP no custom rom!
If anyones thinking of updating and reading this topic, stay clear of the Oreo 8.1 update for the SM T585. Once installed theres no turning back.....so it seems
Thanks for replying.

just flash the nougat firmware from SamMobile. You have to flash all the 4 files in the zip you are going to download. AP, CSC, etc. Once you have your tablet completely stock you can install again TWRP and flash whatever CUSTOM rom you want.
I easily rooted the phone with odin flashing only the TWRP in AP box (twrp taken from this post https://forum.xda-developers.com/showpost.php?p=78145080&postcount=160) avoid the auto-reboot. You have to put the tab in DL mode, connect it to pc, start odin flash the twrp in AP file e unselect Auto-reboot. As soon as the process is done you have to log in recovery mode at the first boot with home + power + vol up and flash dm-verity. I rooted with Magisk without any problem just flashing the v17.3. Now i' m back to nougat (from Oreo) and i can install whatever custom rom i want. But honestly the only one fully working is Lineage 14.1. Resurrection remix 6.2 has problem with camera and gps don't lock. Same for Oreo version. Tried Pie, same problem.

Domenico F
Thanks for the info.
I tried to install MM 6.01 & Nougat 7 stock rom and they wouldn't install, no matter what I did. ( see Odin pictures )
The last chance was to try Oreo 8.1 again and I did manage to reflash the 'Netherlands stock Oreo 8.1 rom' (after 10 hours!) using all four files (AP,BL,CP,CSC).
I then reset the device a couple of times via stock recovery. Took the OEM lock off, theres no FRP lock either. Enabled developer mode > debug mode (all the usual setting changes prior to rooting / twrp install).
At this point the imei and sim card network ARE recognised and work on the device as normal.
HOWEVER I found once I rooted by any genuine means > Magisk v16 (patched boot img taken from stock rom) and also the CF gtaxlltex sm t585 auto root method.
And when the device booted back up, the 'imei and sim card' WERE NOT usable, nor recognised, no network...........I also noticed BusyBox wouldn't install at all, message about integrity of root.
Adaway and Lucky Patcher recognised root.
I also then tried installing TWRP 3.0.2.0 -3.2.3.0 from many locations and again, none of them worked at all. Just blue lines, fuzzy screen etc. On some occasions Odin wouldn't even process the files.
I include pictures of the files I used.
Its evident to me that I can use the device normally i.e sim card , make calls, data etc if I don't attempt to install root / twrp recovery.
So no root , no twrp , then no custom rom usable or installable. It sounds like Samsung are out to stop custom software on their products.
If the Netherlands stock rom 'BL' (boot loader) file is encrypted with this new binary v3 or v4 to stop OS modifications. I wouldn't recommend using it when flashing the new Oreo 8.1 rom or future new releases.
The best way is to just use the AP file ONLY and overlap Nougat 7 or MM 6. And because you've kept your original BL from earlier stock roms, it may be possible to downgrade back to MM or Nougat if need be.
Once the latest new Oreo / Pie 'BL files' are used in the Odin flashing process, it causes big problems.
Hopefully, maybe someone smart enough can find away to decipher these new BL files and offer a replacement method. which will allow software downgrades and modifications

Honestly i think this run for Oreo it's not really worth. I said you what I did and now i have no problems. I'm not in hurry to use Oreo (as stock rom). I think Lineage 14.1 is the most stable and fastest rom i tried till now, and most of all everything is working. I think i'll give a try via Odin to the official stock rom when it will be available for download (i live in Germany) but sadly I don't use most of the Samsung bloatware installed by default.

WRP Oreo 8.1 on Galaxy Tab 10.1 (T585)
Then I've tried
twrp_3.2.3-1_sm-t585_29918 which gives only stripes when booting into recovery
Do I have to flash the stock boot/recovery before flashing this one,
or this is broken, as well.
Many thanks for a hint,
Helmut

Hope this helps.
So, as I was trying to search for my Galaxy Tab A6 (SM-T585) for Deodexed Stock ROM, I stumbled upon this thread https://forum.xda-developers.com/galaxy-tab-a/themes/mod-twrp-odin-t3650215 just follow the instructions to fully flash Oreo. By the way when flashing Root, I would recommend Magisk Beta https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
it does not damage the IMEI at all(Thread here, read the comment:https: //forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445) . The TWRP, I think we should leave it be, don't flash an update for the TWRP.
Thanks. Hope this helps.

Neither does a custom recovery, so not sure what your point is?

I mean if your having problems using MAGISK use the beta version

TWRP, Rooting and Custom Rom HELP SM-T510 Tablet Tab A 10.1

Hey guys, this is my first post. I just bought a Samsung SM-T510 and would like to unlock all the features. I'm currently trying to follow multiple guides on how to do so. To my understanding, my best bet is lineageOs 16. I've been following https://forum.xda-developers.com/gal...-16-0-t3987317 alongside with https://forum.xda-developers.com/gal...howto-t3989361 and I'm pretty confused on the method order i need to follow. What I mean is do I install rom first, TWRP, Magisk etc.?
More guides ive been following:
https://forum.xda-developers.com/gal...-10-1-t3934805
https://forum.xda-developers.com/app...mless-t3473445
https://topjohnwu.github.io/Magisk/i...system-as-root
I see posts saying I need and don't need Multidisabler so I'm confused on what I actually need: https://forum.xda-developers.com/gal...ption-t3963020
Another one: https://forum.xda-developers.com/gal...ption-t3919714
https://forum.xda-developers.com/gal...eries-t3918699
I have so many tabs open currently; I know I'm missing a few important ones.
So given all that info, i think i have all the software to do this between kernels, rom, twrp, odin, magisk, multi disabler? and i think thats all.
My sm-t510 build number is T510XXU2ASK5, looking through the lineage rom guide, I click the link https://samfrew.com/model/SM-T510/ and i see different versions. I'm honestly completely confused about this file and how I'm going to use it. I understand it to be the stock rom? as in factory software? With TWRP too, the numbers don't match my current build number leaving me very confused.
Do I need to downgrade my build number (i don't know if it's even a thing just asking)?
I think i can do everything relatively easy once I have an understanding of what to do first (order of things) and the specific files for the specific steps. When I'm reading these guides, I honestly have no idea which download goes for what. For ex. going back to https://forum.xda-developers.com/gal...-16-0-t3987317 like what do I need to download, the build number listed in notes regarding kernel or go to the download section right below and use that? Or both and if both, how do I use them separately for there a specific purpose? I cannot find anything that makes me feel comfortable rooting/custom rom on my device. Not comfortable in terms of I don't know what I'm doing exactly. I have put days of reading into this and still, I cannot figure out how to do this. I would really appreciate it if someone could help me. This is stressing me out and I would like to get this done before Monday due to me having some serious surgery. The reason being; I won't be as fresh on everything I've read recently.
I'm sorry if this post is choppy and all over the place. I'm just exhausted and clueless at this point. If I left any info out in order for someone to help me please let me know so I can provide it.
EDIT: The TWRP file ends in build number SK1, the file lineage-16.0-20191019-UNOFFICIAL-T510XXU2ASI4.tar.md5 doesn't match the TWRP file as well as my current build number; which ends in SK5. So nothing is matching the 3 last characters in my build number across all guides besides the samfrew link.
Also, I keep seeing i need a .tar TWRP file for recovery (?) but when I unzip both files are .img (named boot/recovery)

You don’t unzip the .tar files. Keep them as is.

I don't get a .tar file until I unzip the folder; I get a filed with .tar.md5

My recommendation would be to first upgrade to T510XXS2ASK1 of the OEM firmware, since that's the latest version for which Samsung has published kernel source. Use the latest release of Odin and install BL, AP and HOME_CSC. After this, unlock the bootloader and prevent VaultKeeper from relocking it by always enabling Debugger Options while connected to the Internet after a factory wipe.
From there, you could just install TWRP, install the latest MultiDisabler, and live with the Samsung firmware. You could even install Magisk to root. However, I prefer a clean Google OS without all the OEM bloatware, so I'd recommend installing the latest Nexus Stock (which includes TWRP and the custom kernel that disables Knox boot security features). Again, use Odin and install it to AP and do a factory wipe in TWRP because file-based encryption is still unsupported on these custom ROMs.
You could install LineageOS instead, but I haven't yet updated that for T510XXS2ASK1. I've just been busy and Andy hasn't been releasing any new LineageOS 16 GSIs. We're also pretty close to releasing a LineageOS 17 build.

Just rename the file cutting off the .md5.

is it possible to downgrade from sk5 to sk1? you cannot upgrade to a later version, and I know downgrading can have reverse effects on the tablet. I have same tablet I would like to know. if I flash sk1 is there a way to fix it if it bricks?

My sm-t510 build number is T510XXU2ASK5, looking through the lineage rom guide, I click the link https://samfrew.com/model/SM-T510/ and i see different versions. I'm honestly completely confused about this file and how I'm going to use it. I understand it to be the stock rom? as in factory software? With TWRP too, the numbers don't match my current build number leaving me very confused.
Do I need to downgrade my build number (i don't know if it's even a thing just asking)?
I think i can do everything relatively easy once I have an understanding of what to do first (order of things) and the specific files for the specific steps. When I'm reading these guides, I honestly have no idea which download goes for what. For ex. going back to https://forum.xda-developers.com/gal...-16-0-t3987317 like what do I need to download, the build number listed in notes regarding kernel or go to the download section right below and use that? Or both and if both, how do I use them separately for there a specific purpose? I cannot find anything that makes me feel comfortable rooting/custom rom on my device. Not comfortable in terms of I don't know what I'm doing exactly. I have put days of reading into this and still, I cannot figure out how to do this. I would really appreciate it if someone could help me. This is stressing me out and I would like to get this done before Monday due to me having some serious surgery. The reason being; I won't be as fresh on everything I've read recently.
I'm sorry if this post is choppy and all over the place. I'm just exhausted and clueless at this point. If I left any info out in order for someone to help me please let me know so I can provide it.
EDIT: The TWRP file ends in build number SK1, the file lineage-16.0-20191019-UNOFFICIAL-T510XXU2ASI4.tar.md5 doesn't match the TWRP file as well as my current build number; which ends in SK5. So nothing is matching the 3 last characters in my build number across all guides besides the samfrew link.
Also, I keep seeing i need a .tar TWRP file for recovery (?) but when I unzip both files are .img (named boot/recovery)

without reading answers i can say that im with YOU! Im almost 3 days to root my T510! We must RAMDISK YES in Magisk but to do that we need to extract recovery.img (https://www.droidwin.com/install-magisk-in-recovery-root-android/) from stock original ROM T510OXM5CUJ1 and Im stucked at the part NORAMDISK trying to patch recovery.img with Magisk Manager (with recovery mode checked) but i only get the "waiting for device in ADB" and I conect disconect USB C and nothing...Still NO RAMDISK...
I used 3 different ROMS but no lucky and tried with firmware CUJ1 but no lucky again. Without "NORAMDISK: YES" no root...stucked. But i saw a T510 with OrangeFOX!

I just finished flashing the latest Nexus ROM and rooted it with Magisk merely by flashing the Magisk zip file. You can flash the Nexus ROM without first flashing anything else but the latest CUL1 (not CUJ1) stock ROM. Nexus includes both TWRP and gapps. The only time you have to patch things to get Magisk installed is when you are trying to root a stock ROM instead of a custom ROM. Custom ROMs always to the patching for you.

UPDATE: So...flashed with T510XXU5CUL1...
From OEM stock firmware:

Hold Vol Up & Vol Down buttons during restart to enter Download mode
Install TWRP to AP with Odin --> twrp-3.6.0_11-2-T510XXU5CUL1-20220218.tar ---> this put the tablet into emergency mode... had to do again "Hold Vol Up & Vol Down buttons during restart to enter Download mode" and reflash it again. stucked at this point. cant flash TWRP with that!

You don't need to flash TWRP if you flash https://forum.xda-developers.com/t/...k-for-2019-galaxy-tab-a-10-1-sm-t510.4234889/ TWRP is built into this ROM. After installing stock CUL1, did you boot it, connect to wifi, skip the rest of setup and then enable Dev mode before rebooting to download and flashing from Odin?
edit: Don't attempt to download from the regular download link. Use the link under Build archives that says Android File Host and scroll down till you find the CUL1 md5 file.

You must connect wifi and enable Dev mode before flashing. If, after flashing CUL1, you went through the regular setup routine and put in a Google Account, you must also enable OEM in Dev options.

USB cables are notorious for being flaky. Sometimes it helps to just turn the cable over and plug it back in. I always keep several on hand so that if I have connection problems I can try another cable.

[Help] I can no longer access wifi after flashing TWRP

So i've exhausted almost every xda thread I can find, and finally decided to make a post myself. This is maybe the 6th or 7th time I've had to MSM tool my phone because I softbricked and could only access bootloader. I'm a newbie so you may need to go in detail in what I should do. All help is very appreciated.
I'm trying to flash a new ROM to my phone, the one in question is the latest nightly build of LineageOS: lineage-17.1-20200806-nightly-fajita-signed.zip, the ROM itself works fine, however, flashing TWRP after flashing this rom (even if I wipe dalvik/cache) I no longer am able to access wifi). I've flashed stock and started over about 5-6 times (from the very very beginning, including unlocking the bootloader) and I'll always end up with a wifi issue or a bootloop.
I've tried multiple different versions of twrp, including the unofficial 3.3.1-32 Q unofficial builds from this guide and both 3.4.0-0 and 3.4.0-1 from the official website, both leading me to the same results. (the unofficial build wouldn't decrypt, so I failed with that one).
I'll go through the steps I do in detail, and if anyone sees an issue with my process, please correct me.
1- enabled developer options
2- enabled usb debugging and oem unlocking in developer options
3- booted into bootloader with
Code:
adb reboot bootloader
4- checked to see if phone is connected and unlocked the bootloader with
Code:
fastboot oem unlock
5- set up my phone again, enabled dev options, and enabled usb debugging again.
6- booted into bootloader again
7- typed this into the terminal to temporarily boot TWRP
Code:
fastboot boot <recovery_twrp>.img
7.5- flash copy-partitions.zip from the LineageOS install guide
8- went to advanced>adb sideload>swiped then went on adb terminal to sideload TWRP installer
Code:
adb sideload <twrp-installer>.zip
9- went to menu>reboot>recovery
10- after rebooting went to wipe>factory reset slide>swiped slider
11- went back to menu>advanced>adb sideload>swiped then went on adb terminal to sideload (while checking wipe cache/dalvik)
Code:
adb sideload <lineageOS-rom-nightly>.zip
12- tapped reboot system
this is where things begin to go wrong:
- i notice that I can't boot into lineageOS, lineageOS claims android data is corrupted and needs to factory reset
- factory reset phone
- boots up fine, go through set up process (wifi works right now, only problem I notice is that within build settings, it shows a completely different phone number on my SIM card rather than the phone number I actually have, but it doesn't look broken or corrupted), enable usb debugging again, boot into bootloader
- type
Code:
fastboot boot <recovery-twrp>.img
- twrp loads up fine
- go to menu>advanced>adb sideload>swipe to begin sideload then type
Code:
adb sideload <twrp_installer>.zip
- reboot system
- boot process takes forever, (restarts 3-4 times) phone feels sluggish, and wifi will no longer work (data works fine)
- i give up and I MSM tool my phone.
I genuinely think this is because of TWRP, I read through a few xda threads claiming that the official 3.4.x builds had many issues, and therefore would reccomend using 3.3.x builds. I tried both from the official website and the unofficial TWRP by mauronofrio, where i get decryption problems on both of them. only 3.4.0-x TWRP builds would get me as far as flashing the rom. I've tried this process on both android 10.3.0 and 10.3.5
I genuinely would like some help. this phone is my daily driver and not being able to use TWRP (let alone properly flash a ROM) is a big problem that destroys what I loved about my phone in the first place. Thanks in advance.

I'm assuming this is not a TMobile 6T. With that assumption.
Try my LOS install guide. Note I couldn't get the 10.3.5. fastboot ROM to work. However if you are already on 10.3.5 stock, you are fine, just go with it. I updated manually to 10.3.5 using TWRP, and then used the latest weekly build and everything has been fine. Just go straight to the TWRP step. Other wise use the 10.3.4 fastboot rom. Cliff notes version in the second post.

Follow this thread. If you're losing WiFi in stock from flashing twrp, there's way to prevent it

this worked!! thank you so much for such a great guide!
I did one thing differently though, instead of using the fastboot rom or running it through scripts, I used the copy-partitions.zip file available on LineageOS' fajita install guide to make both partitions appear the same. I realized my mistake when I didn't flash the rom twice, as that's mandatory when it comes to A/B partitioned phones
Everything works smoothly! thanks!
