LTE Loss, Unable to Recover w/o Factory Reset - with Several Protections in Place - Verizon Samsung Galaxy S III

Greetings,
I've been racking my brain and fighting with this for weeks now, but I'll try and keep this short:
GS3 d2vzw
Unofficial Lineage ROM 14.1 (Nougat 7.1.2) and OctOS-N (also 7.1.2)
With, and without, Xposed Framework/XPrivacyLua
AFWall+ (firewall)
When I go into a cell dead zone, I lose LTE and never get back. I'm always stuck on 3G with a little 'x' in the bottom-right corner of my 3G/Signal icon. However, the little 'x' can go away depending on the AFWall settings (i.e. allowing phone services out, or kernel, etc).
The only way I've been able to get LTE back is to backup the ROM, Factory Reset, and then restore the ROM...and even that doesn't always work. It seems to depend on if I do a Factory Reset or Wipe the device including the data partition. Also, this technique seems to only work when I restore an OCTOS Rom. The LineageOS ROM has NEVER recovered LTE. However, the LineageOS ROM still has Xposed installed.
Online, I found a recommendation to "Reset APNs to Default", clear cache, restart. This also has never worked...plus, I don't know what 'cache' they're talking about. I've tried clearing the Phone cache and/or Dalvik/cache from recovery...neither have worked.
I don't believe the problem is with the SIM or HW as a factory reset has always brought back LTE. I also don't believe Xposed is the culprit as I've had the OCTOS ROM without it. This ROM I can factory reset to get LTE back and restore an OCTOS ROM which will then still have the LTE. LineageOS I have yet to try to see if removing Xposed will have any effect.
I was leaning toward the problem being AFWall+ as I block a TON of stuff. However, when I disable AFWall and restart the phone, LTE still does not come back. It's almost as if the radios are somehow dropping to 3G and then unable to recover w/o factory reset...but I have no idea what "factory reset" is doing.
Any and all help would be appreciated as this is my only phone and constantly factory resetting/restoring is not practical simply because I drive through a dead cell zone.
Thanks!

UPDATE: I adjusted the firewall settings a bit and was successful in restoring the LineageOS after Factory Reset to /keep/ the LTE. Still doesn't solve the recovery if LTE is lost though.

Just a suggestion...
Do you have the latest Firmware Modem installed as reflected on the following thread?
https://forum.xda-developers.com/showthread.php?t=3735628
The Firmware Modem updates are specific for devices to Update the Modems Only without having to flash the whole Firmware to update them (typically for devices with Unlocked Bootloaders).
Keep in mind that Custom Firmwares doesn't update the Modems and leaves them alone. Modems has to be updated separately by the user.
Good Luck!

Thank you! Turns out my modem firmware is from 2013! So yes, I would like to flash the latest modems, but these files all point to ODIN. Does anyone know if /heimdall/ under Linux can be used to do this as well??

The ones from that thread are customized with only the Modem Update files.
Those modem updates are only flashed in Odin per the OP instructions.
You don't need to reset, recover, etc... your device stays the way it is with an updated Modem. You just flash it via Odin, it reboots and your all set.
That's my DevDB Thread and I tested all of those Modem files to make sure that they worked.

Bummer. I don't have a Window box for ODIN. I did extract the .tar and found the NON-HLOS.bin file and some research shows Heimdall can flash those to the modem partition. However, I also found this site: https://forum.xda-developers.com/showthread.php?t=2791801
Which says it will lock my bootloader. Now, granted, the file provided is a full modem+ROM flash which is something I don't want to do. However, since the flash name used "VRUDNE1" is the same as the version number listed on your modem list provided by your link, I thought I'd ask and verify: Will flashing just the modem file affect the bootloader in any way? The last thing I want to do is risk locking my bootloader.
Thank again for all your help.
BTW, I downloaded the full 4.4.2 update for the GS3 and figured I'd look for the "modem file". I found this page that shows there are 2 files, one for the LTE modem and one for the 3G modem. Thoughts?
I just want to be extremely cautious about this since I don't have a Windows box and I don't want to lock my bootloader.

I have a TWRP flashable ZIP of modem NE1.
Get it here: https://www.dropbox.com/s/i15enyq8wm759z9/d2vzw_MF1_firmware_NE1_modem.zip?dl=0
Flashing this file will NOT do anything to the ROM or Bootloader.

Shield Tablet LTE US to RoW Modem Files

I've written a blog post that describes how to flash the RoW factory images on the Shield Tablet US version.
http://jaredmorgs.github.io/2015/01...-US-Version-into-a-Rest-of-World-Version.html
Everything flashes OK, but the one thing that's missing is the Modem files.
It seems that the Modem files are not included in the factory images, and one suggestion was to wait for an OTA to land then you would get them. But that doesn't seem to be the case when installing the 5.0 (OTA 2.0) factory images.
Does anyone know how to get access to the required modem files to flash through ADB to the device? Would I need to pull them from the very first factory image set? Would I need to pull them from a random OTA between 4.4.2 and 5.0.1?
And if so, has someone already extracted the modem files to a side-loadable zip?
It would be great to be able to change the LTE bands.
So if anyone has any solution for this...?
The blog post has an answer from someone who confirms that both modem firmwares are loaded on the device, however a check by the upgrade scripts determines whether the US or RoW modems are flashed.
As yet, I'm unable to confirm how to force the tablet to load the RoW firmware.
there is a thread currently looking at this:

6045i usa latest 5.0.2-01001

hello i am rooted with twrp recovery installed. I was able to unroot and download the latest 5.0.2-01001 ota but im not able to install the update it would just take me to twrp recovery and stop there.?? i found the update zip and tried to flash it in twrp but it says it cant mount and failed to flash any help would be appreciated.
OTA updates will require a stock recovery. I'm in the process of getting an Idol 3 but I used to have an Idol 2 and, to return to a completely stock ROM, I had to use the Alcatel Mobile upgrade too which identified my phone, downloaded the correct firmware, and restored the phone. Prior to restoring back to stock, I had cwm and root.
Thanks for the reply I tried the software update but its not working keep saying I have the latest even when I did a full wipe. Using the latest 4.9.2 version...is there a way to make a twrp flashable ota zip from the downloaded update file in the ota cache..

You cannot be rooted and install a stock update...it's mentioned in several places throughout the forum. Quickest solution is to use the mobile q to restore the whole phone to factory (and in the process it will put the latest version on it). Otherwise you have to fully unroot AND if you have modified any files such as build.prop or other system files it still won't work. You CAN install with TWRP however in the process of the install it will overwrite it with stock recovery. If I had to guess I'd say you did not do the supersu FULL unroot.

mobile Q is horse manure now. I ran into the same problem, whereby it says you're up to date (which it's not), even if you're running 5.0.2.7SMA-UEA1 ! I only know that one because I inadvertently flashed 5.0.2.7SMA-UEA1 today when I meant to flash 5.0.2.7SRA-UEA2.
Speaking of 5.0.2-01001, 5.0.2.7SRA-UEA2 is on longer the latest yeah... anyway we can update the firmware page? http://forum.xda-developers.com/idol-3/general/want-to-able-to-install-ota-updates-t3163745
I just tried to OTA update to 5.0.2-01001, but OTA of course does not work if TWRP is acting recovery; it just reboots to TWRP and then if you reboot system, nothing happens. Although seemingly never mentioned, we must remove TWRP (even read only TWRP) before updating OTA?

The thread is closed. There is also no reason you NEED the most recent posted as you can flash any of them and then do an update. Mobile Q is the recommended method to re-do your phone if you can't manage to make a backup before messing with it. It has apparently worked just fine for people in this forum for every model type mentioned so the burden of proof is on your part if you can't get it to work.

Why would the thread be 'closed'. OP's problem is unresolved.
'Worked' is the operative term for. Perhaps you haven't used to Mobile Q tool lately? As OP (and I) said (today), running OTA from 6045 now just reboots to TWRP, no install. Alternately, when attempting to update 6045 from Mobile Q, it just throws a funny English 'update no needed' kinduva message (pic). Incidentally, have you been to their website to find an update to this tool? Holy crap, in that respect, Mobile Q must be a virtual breakthrough for these boys! :laugh:
You're so helpful here famewolf. I've both appreciated and have been comforted by seeing your knowledge all over this subforum, since day 1. Please provide help. You tell me where this 'people' person is, and I'll wank on his boner for you. Then we have a definition of 'working fine' in stead of 'worked fine'. ? :angel:

The thread that is closed is the one YOU mentioned.... not the op. http://forum.xda-developers.com/idol-3/general/want-to-able-to-install-ota-updates-t3163745
I dont use mobile Q as I use Linux and they don't have a linux version. I use 3rd party roms such as AICP with the ARDE non OC rom. TWRP puts a log in /tmp...did you look at what the error message says? OTA updates will NOT apply if you have updated system files such as build.prop. Thats all I can tell you because I can't try what you are using.

I haven't updated the build.prop, I doubt the OP has either.
'There is no greater software version available to upgrade your phone,actual version of your phone is the latest'
Hehe! Only thing that would make this funnier is if they misspelled 'version'. At least I can derive some amusement from that message and their ****ty, convoluted website.
Shame you can't help on that front, but maybe you can at least guide me on what should be normal flow of this procedure.
When one does OTA update unrooted (but with custom recovery), at the point that the phone reboots, it should not (in theory) boot into TWRP right? I would think just continue with update, and maybe that's why I would need to remove TWRP in favor of stock recovery.
It would be easier to attack it from that angle as opposed to their crappy win32 program. which they probably didn't pay the GoDaddy bill on.:laugh:
I don't even know why I'm bothering as it's just a backup phone now. I just find it ridiculous that I can get their last measly update either from Q or from device (ostensibly so long as custom recovery remains). Holy bejebus, updating Shamu is so painless (6.0.1)
---------- Post added at 08:41 PM ---------- Previous post was at 08:22 PM ----------
likely they have not updated their server side to to UEN0 from UEA2 for their craptacular tool which would explain that problem.
Curious, did you lose Band 12 with UEN0. I haven't heard anything positive from this most recent update that is giving me a headache to get to. Perhaps it's for naught. They don't even have a changelog do they. Meh... I'm going to forget about it until something notable comes along or maybe even just sell this thing while I might still get over a hundred.

As I mentioned here: http://forum.xda-developers.com/showpost.php?p=64967202&postcount=4 you CAN install an OTA update with twrp...it will install it just fine however at the completion of the update you will no longer HAVE twrp installed because it will have been overwritten with stock recovery. (it does that at the END) This will be apparent the NEXT time you try to load recovery. Where do you imagine the update is processed? It's processed by the recovery app...it can't be done inside the rom because files would be in use. The last version I ever ran was UER0..was not even aware UEN0 was out. As I indicated, I switched to a rom based on cyanogenmod with some features I wanted...if I was going to switch NOW I'd choose blisspop and it's the one I intend to install the next time I have to do a reinstall. I don't see why you fight on 5.02 when 5.1.1 is available in various flavors and with the ARDE NON OC Kernel is rock steady. If you made full backups of your device (ie dd images of ALL partitions using the Backupall bat file or shell script running around the forum restoring to a previous radio is as simple as reflashing the partition using fastboot commands.
The radio is stored in the "modem" partition fyi.

So where is the latest update to flash with twrp (good dry run for me should a decent upgrade come out that isn't UEN0)? I just went with UER0 posted on yer thread thr with all the megaupload firmwares & flash restored system & boot (after full wipe); as an aside, it took, & I still have TWRP in tact. I'm well aware of your fastboot method & orig backup of ALL partitions. Seemed like a waste of space at the time, still kinda does.
Regarding your rhetorical question, I was referencing Alcatel's w32 Q tool. It seemingly wasn't updated to be keyed in on the latest update either. No wait, it said the same 'no greater version' crap even when I restored the original 6045i US system/boot fw from twrp, lmao

Why are you assuming I should know where the latest and greatest update for stock should be? Updates are customized based on the rom version you are running at the time you submit a request. I've already stated I'm using a 3rd party rom and using an OS that doesn't allow me to run their software. You consider my recommendations a waste of time so I'll quit making them and continue using my perfectly working device on 5.1.1.

Omfg buddy, you said, '... you CAN install an OTA update with twrp' ; all I did was point out that I flashed previous updates (presumably the same way you're talking about), TWRP remained in tact afterward, & asked you to follow through with that point with, you know, the actual update in question here that defies many of your assertions. One of your recommendations is broken (Q), the other is hindsight (full backup) & last (update via TWRP) seemingly not feasible (unless someone were to submit updated /system) . Anyway it's all a moot point now since we're just measuring our junk.
I'm tickled you're running 5.1.1, as you've said repeatedly... I tried it briefly on Shamu & was happy to leave the LP quagmire all together & get to 6.0.1. Sufficed to say, there isn't anything perfect about this device or 5.1.1, which is why I'll leave as is & sell it. :good:
Thanks anyway.

features not working on galaxy S3 after screen/frame swap.

Hello!
I have a SCH-I535PP that has a bad screen and a SPH-L710 that has a good one. I stripped them both down to the "frame" of the screen and replaced all the SPH's innards with the SCH's, besides the front facing cam because the screw is stripped out.
The problem with this is that the pcb is not meant for this "frame" and I have to leave a screw out so that it doesn't sandwich the pcb that connects the upper and lower sections of pcb, possibly un-connecting something as I screw it together. I also had to leave out the black screw as theres no hole in the SPH's frame.
So, the features I'm missing is the camera, vibration, wifi, and the home button. However I'm not sure if the home button worked on this frame so. But if that's the case (which is might be because I can't get into recovery) then I can't clear cache to see if that would fix the said hardware faults.
Worse comes to worse I just need the wifi really, but having the rest of it would be great. Any suggestions?
Thanks so much!

The Digitizer Assembly is compatible between the two models but, not the specific electronic components.
That's pretty much the bottom line...
The ifixit.com website has excellent guides with images if your looking for one too.

Great, so I have a phone that barely works. Least I got my data off it. Still though, there's got to be a way to fix it. I don't care about the vibration and home button but the wifi and the camera are crucial. I still get cell reception and bluetooth, but why don't I get wifi? Doesn't make any sense. It goes to turn on in the settings and turns off. I swapped over the antenna after using the doner phones one, is that what caused it? Using the older phones one? Or is the wifi section directly on the pcb? Maybe it got pinched somewheres or unplugged? No idea.
Thanks for the help!

Alrighty, good thing I have a home button emulator app and terminal emulator I can add su and reboot recovery. However I'm not sure which modem driver I should use? I have the I535PP, not sure where I'd find the file I need to flash in the samsung recovery. Also I got the phone a while ago, it has android 4.4.2. I did a factory reset when I got it, however I've been using a work around to get around the activation screen. I was told if you act like you're going to use the phone with a different sim they'll activate the phone, should I try that? Or should I try and flash a different software to it? Also I've heard of a thing called knox sensor? Will that go off and brick the phone if I try to flash a different version of w/e to it? Also I should add that the phone was rooted with kingroot.
( I've got a sdcard I'll put it onto, it's a .zip right? There anything else I should know about? )
Also, my basebrand version is: I535PPVRUBNF5
Thanks so much!

I believe that the NF5 is the last one released.
I really can't give you much more information than this. I've never had the Prepaid S3.
If you need the Stock Firmware for the I535PP NF5, i do have it on my File Host Account. I uploaded it for another member a while ago and kept it there.

Okay? So should I make a backup and restore it with that firmware? That's basically the same as doing a factory reset right? Should I try to do a factory reset first? I'm new to all this so what should I use to backup? Just the standard android thing (if there is one). Restoring from that backup wont bring my issues back will it? Or is the whole firmware thing just essentially "drivers"? and doesn't reset the phone? I'm confused.
Also could I get the link to said firmware? Again, thanks so much!
I also found this: https://forum.xda-developers.com/ga.../rom-tw-4-4-2-i535ppvrubnf5-deodexed-t3427237
Seems to be a modified version of the OS/firmware. Idk if it'll work for my phone though. I need a modified loader or something? Any suggestions?

First of all, here's the link for the stock Firmware (it's zipped up so all you need to do is unzip it).
https://www.androidfilehost.com/?fid=745425885120750115
That other link is a modified stock Firmware. It's basically the stock Firmware that's debloated and other modifications that's outlined by the developer.
Since the device cannot be unlocked for a custom firmware, that is basically the stock Firmware that's modified and only has what's needed for the devices recovery to think it's the real deal.
I have an S4 that can't be unlocked but, it's got the stang5litre firmware that's modified the same way.
I hope i explained it okay via text...

Well with you saying it's not unlocked, when I first boot the phone it says custom with an unlock padlock? Is that what you mean? So am I set to try and flash that de-bloated version and try it out? It says there that I need safestrap. No idea what that is but I looked into it some, should I try and use it to flash that version or use the standard samsung recovery? Or will it not work that way, probably not.
Also the link you sent me I got a "504 Gateway Time-out"
EDIT: I rooted it with kingroot and I'm fairly certain that it made the custom bit appear. Did it disable the knox sensor or something, and make it to where I can flash custom roms or w/e?
EDIT2: The site was temp down, got it now.
Alright, I downloaded the file you sent me. Going to copy it to my sdcard. Is there something specific I should name the file? Also I want to extract it so it's .MD5 not .zip like you said? Also what option do I select in the recovery mode? Apply update from external storage?
Thanks so much!
Well I can't even connect my device to my PC. It wont show up. I had this problem before and I can't remember what I did to fix it... Keeps showing up as a modem. I've installed the correct drivers though. wtf... Then tried samsung keis, didn't work. Tried samsung smart switch which said my device was supported but when I went to connect it, it decided it wasn't..... I'm trying USB driver version 1.5.14.0, but when I connect my device windows update installs more ****. Is that the problem? It keeps installing the wrong driver? Idfk starting to get annoyed now lol, going to take a break from it and see what you say tomorrow.
(it's not the cable either, I'm using the data/charge cable from my logitech g700s)
Thanks again.
Edit: I'm on windows 7 x64, and in the devices menu it's showing as a modem.
I've been looking into it a little more. I found a loader called TWRP. However I can't find the specific I535PP version, again, or is it this one?
https://twrp.me/samsung/samsunggalaxys3verizon.html
So if I installed that, I should be able to install that custom rom? A de-bloated version would be great, it runs a little slow, and gets pretty hot playing games. Plus a little change too, but I still need to backup all my data and some game saves. I just need to be able to access it from my pc >_< I've format'd my pc since I had it working last
Edit: The rom install instructions say to use either safestrap or flashfire. I'm not sure which one to use, or if I should try to use the TWRP. Or if I should try neither of them because I might brick my device? Idk, can't wait to hear from you. Or should I just forget about all this and try and flash the original firmware you sent me?
Edit2: I also made a thread here asking the same questions.
Thanks!
Unfortunately I still can't get it to connect to my pc. There's a bunch of other threads I've looked at but trying different things haven't made it work.
Any suggestions?
Thanks.
wtf, even booting into download mode does nothing when plugging it to my pc. I have no idea what's up with this phone... It says the following up at the top left:
ODIN MODE
PRODUCT NAME: SCH-I535PP
CURRENT BINARY: Samsung Official
QUALCOMM SECUREBOOT: ENABLE
BOOTLOADER RP SWREV: 2
It's also stuck in download mode now, and just says "Downloading... Do not turn off target !!" Wtf is it downloading???
It's great that I have an overcomplicated flash light essentially, or if I restart the device possibly a paper-weight. I'll give it a little longer and see if it'll shut off by the button, if not I'll pull the battery.
Edit: It was fine, but still an overcomplicated flashlight. I guess you normally get out of DL mode by holding home which doesn't work for me, but removing the battery was fine.
Another unfortunate thing is that I can't enable mtp mode because of the weird way I have to get into the phone. My notification bar doesn't exist at the top, when I was first using the phone it would randomly pop up and work out of the blue, but if I restarted the phone or hit the home button it would send me back the activation screen, therefore having me to go into settings and enable standard home screen mode and a couple seconds later it pops to the home screen or lock screen if I don't type my code.
Any idea what the number is I have to dial specifically for the I535PP? By VZW? I've tried them all
Hope you haven't forgotten about me @Ibuprophen xD Sorry for all the questions.
Thanks and look forward to hearing from you!
Also I just found this video
https://youtu.be/9LLOmoE-tp0
So from what this vid says do I just click AP on odin while my phones in download mode, click the file you sent me and let it go? I don't think the same would apply to the other flash install, as it isn't compiled into a .md5 format.
But again I still haven't been able to back some files up off my phone. Only if my pc had bluetooth, because that surprisingly works on the phone. Might just get a usb bluetooth adapter if I have to... So annoying, idk what I did last time to fix it...
I really do apologize @Sokoloft for not responding to you lately...
I've just been getting a bit swamped with various items regarding my current developments, unreleased developments, various other XDA responsibilities and my personal responsibilities at home.
After a quick review of your posts here, i am not sure exactly where you are at now and even what your trying to do now exactly.
I did notice a question or two on other posts and, though their not bad questions in itself but, they are actually reflecting (to myself and others) that your not really reading the OP's nor are even searching the threads themselves for previously answered questions from other members that match/are similar to your question.
I'm not trying to nor is it my place to lecture any member but, I'm just providing you with a reflection of what I, personally, am viewing/understanding.
I just want to quickly add that if you're that lost in what you're doing, i can only recommend/suggest (in a friendly way) to do your homework by looking into and understanding what you want to do, is it possible to do and how those actions affect your device.
With that stated...
I just want to remind you of 2 things that I've stated on a previous post(s).
1) I don't have/never had the Prepaid S3.
2) There's no way to unlock the bootloader of your specific prepaid device.
The post regarding that customized version of the stock ROM is a good alternative as well as (i think it's available for the S3 Prepaid) the stang5litre that's also a customized version of the stock ROM.
If you can respond to my other questions (above), I'll try to provide you with some help the best way i can.
Thank you very much for your time, patience and understanding with this!

Okay, so where I am at is that I cannot connect the phone to my pc. It registers itself as a modem still no matter what driver I've tried. I can't transfer files from it that I need, plus I can't get that md5 file on the sdcard if that's what I have to do to flash the file you sent me. Or do I have to use ODIN? Regardless I'm not even sure if ODIN recognizes the device. At one point when I had tried samsung keis it almost established connection with the software, but nothing in windows explorer.
I'll get back to you more on this later tonight.
Thanks again.
EDIT: I had this problem when I initially got the damn phone, and I can't remember wtf I did to fix it. This is immensely frustrating...
EDIT2: I also need the number to dial for VZW I535PP to enable MTP mode as I can't get to my notification bar. That might help? Every one that I've tried doesn't go into that menu. Could it be because my phone isn't activated?
Essentially @Ibuprophen once I can connect to the device I'm going to back some game data up and some photo's and then flash the file you sent to me. Do I use ODIN to do that or put it on my sdcard and use the standard recovery? Or can I not because I have a locked boot-loader? Or can I because it's modified to look like the original? I'm confused...
Currently contacted samsung support, I'll see what they say about it not connecting. This is crazy though, it should just plug up and work without all this bs.
Thanks again, hope to hear from you soon.
I haven't forgotten about you @Sokoloft...
I plan to provide you with a brief tutorial on restoring the Stock Firmware using Odin for your device.
In the meantime, i just uploaded the Stock PIT files for your device. PIT is short for "Partition Information Table" and is used with the firmware file in Odin to tell it how and where to re-partition the internal memory for the factory firmware installation. The PIT file isn't typically needed but, in some cases, it is needed.
The following link is to the PIT files but, be sure to grab the one that matches the amount of internal memory of your device.
The Verizon Samsung Galaxy S3 Prepaid devices were released with 16, 32 & 64 GB of internal memory.

I'll be back with some more information for you.

Efs file problems with my S7 edge.

I recently tried to backup my phone through dr. fone, during the backup, i believe it flashed a download through odin. At that moment my phone turned off. When i turned it back on i found it in a bootloop. Through odin i was able to flash sammobile firmware allowing me to start the phone back up. Weeeellll, according to my phone, i have no iemi, no baseband, no sim card, no ip address. I rooted my phone and found that my efs folder is intact and i have files within it. Im not aware if i have retained all the necessary files to allow it to work, or if the system itself isn't accepting my efs files in general. I rooted it with twrp supersu, used a root browser and am able to see all my efs file, manipulate them and i have plenty of backups to spare, unfortunately i only have backups of whatever happened after my phones info got all f'd up. Here's me hoping that i don't have the worlds most expensive ipod. Please anyone who can help id greatly appreciate it. I need it for work and my constant travel.
There isn't a single thing wrong with this phone, other than the fact i cant access internet, or my network data.

AT&T LG V20 H91020l Flashable Stock Roms

Flash with TWRP, choose one or the other.
H91020i_rooted.zip
You probably want this one. It is stock with the following modifications:
engineering bootloader (aboot)
TWRP 3.5.2_9-0 (recovery)
mk2000 kernel, Magisk v23.0 patched (boot)
hidden bootloader warning (raw_resources)
H91020i_stock.zip
Lose root, revert to stock. After installing, shut the phone off and then do a factory reset.
Lol, thanks for the package. It works just like h91020h, only slightly newer, but i don't have to do the kernel, twrp, or the fixed boot graphic. I can just install this, and debloat.
Works great, installed it with latest TWRP on nougat firmware (initially rooted using dirtysanta)
twrp-3.6.1_9-0-h910.img
H91020i_rooted.zip
Auto_Debloat 2.1
mk2000 2.3 beta 1 kernel
Magisk-v24.3 - Rename .apk to .zip or not, worked both ways in TWRP
Loving it, flashing other mods now like gps, high imp., quad dac mod, etc...
See updates here
Howdy!
Sorry to be asking, but I'm trying this after having been on LOS for ages since I need VoLTE access. After flashing this, I get no service of any sort. Keeps trying to connect, never actually connects. My IMEI is still correct, I've sent my old modem files through fastboot, I've flashed 910 Oreo modem images, no dice.
Any ideas as to what I'm missing in this process? 910 on AT&T, USA, thanks much for your time!

I really appreciate the super comprehensive reply, thanks so much! It was on the carrier's end, it was just a strange case of timing, a worsening of the AT&T nonsense that got me to switch back to Oreo in the first place.
Thank you!
I flashed the rooted zip from this thread after fallowing this guide https://forum.xda-developers.com/t/...irtysanta-most-variants-noobfriendly.3722278/ now the phone only boots the Fastboot. Oddly it even goes to fast mode when I try to enter TWRP it even still makes you choose yes twice like normal but instead of twrp I get fastboot.
Anyone care to point me in the right direction?
Something went wrong, you need to verify you can go into download mode and flash stock kdz and start from there....
[ROOT] HOWTO: AT&T H910 up to v20g (FULLY TESTED)
***WARNING*** This is ONLY for the H910. If you flash H915 firmware on an H918 -- you WILL brick it. If you are currently on Oreo, you can root your phone, but you CAN NOT keep Oreo - for now. This will downgrade you back to Nougat, which is...
forum.xda-developers.com
I formatted data/ and flashed H91020i_rooted.zip onto my H910 (rooted with DirtySanta and flashed to H91020h_Oreo_full_rooted.zip approximately 2.5 years ago). It appeared to work, but it looks like I lost root... whenever I try to do something that requires root, I get "Unfortunately, Magisk has stopped" as soon as the app tries to become root.
Any ideas what to try next?
so could this be used after the root procedure here https://forum.xda-developers.com/t/root-howto-at-t-h910-up-to-v20g-fully-tested.3664500/ ? Because the full stock 910r package used there is no longer available
