May Update Help?

Google Store purchased, currently have root and twrp installed, bootloader unlocked.
I read briefly that to accept the new update and keep root, you have to mess with the bootloader? Is there some sort of simplified guide on this?

Thanks to chainfire, there is a guide for updating to may version and keep may bootloader.
First, you have to flash new factory image or sideload the ota
Let it reboot, now you lost recovery, custom kernel, root etc..
Reboot to bootloader and boot to twrp, flash supersu and the zip provided by chainfire for signing the bootloader
Reboot and you should have root with may update
If you want a custom kernel or twrp you should flash the zips and the verification tool, i didn't understand the right process for this, for me it looped a couple of times but after flashing those files a bunch of times in different orders it succesfully booted with no errors.
I'm currently running stock 7.1.2 may update with supersu 2.79 SR3, TWRP 3.0.1 RC1, franco kernel r15 with no errors, everything running perfectly

Where can we get the May ota download and a refresher on sideloading it? I've done that before but don't do it often enough to get through it quickly... currently running 7.1.2 / NHG47K on my Google bought Pixel which has been unlocked, and rooted. Though I've not installed TWRP, I can bootload into it fine....
My phone app has suddenly started acting all wonky, so I'd really like to update and see if that will help straighten things up.
Thanks for the assistance...

Got the May ota and will now sideload it. Where is this 'guide' that you mentioned Chainfire has setup to assist folks handling the May update?? I'd like, specifically, to get a copy of the zip file that signs the bootloader.
Thanks!!

I am wondering also. Still using NDE63P from October, wasn't aware we could take OTA's at all and keep root. Been having so many Bluetooth issues, it's worth a shot given their focus on it a month or so ago.

Well... up until this recent May ota release, it used to be pretty easy to simply download the latest Superuser zip file and re-install it on your phone, thereby re-establishing root access (assuming your phone is / was unlocked and rooted prior to taking the update). That is not the case going forward.... but I am still researching it.... follow along by looking here: https://forum.xda-developers.com/an...signing-boot-images-android-verified-t3600606

Oh wow, that's super easy. Sweet! Now I need to find out where the past OTA's are so I can flash all of those...
I'm going to give all that a try soon, if anyone following this thread needs help or has questions, feel free to reply here with them.
To dumb down that entire OP into the reason why it's needed: the OTA's being sent out up through April 2017 was just the OTA itself. In May, they started requiring them to be encrypted with a certificate, but didn't provide requirements on from whom the certificate comes from. This means that now, instead of just flashing the ZIP, you first encrypt it with your own certificate and then flash the result of that.
They mention the private keys can be discarded later, given they are generated for the sole purpose of uploading OTA's to the phone, I would think keeping them on the internal SD card of the phone itself would be suitable. Heck, zip those puppies up and email them to yourself, they're not being used for security, why not, right?

Yes, the first link is the ota repositories, download the zip of may, then put it in the adb folder, reboot to recovery, go in advanced menu and start sideload, without wipe cache or dalvik.
Then in cmd just type "adb sideload <name-of-the-ota.zip>"
Let it finish both steps and reboot, then you are ready to boot to twrp and flash supersu and the zip v3 from chainfire's thread for signin the bootloader.
That's it

Agree. Pro tip: after downloading the proper ota update, rename it to something simpler so you can more easily enter that adb sideload ota-filename.zip command!

Expert pro tip: shift+right click the file, "Copy As Path", paste into the terminal.
(I use ConEmu, so right-clicking the terminal itself pastes what's on the clipboard; some Linux distros do this also Command Prompt I think right click is done on the title bar or some obscure thing like that, can't remember).

Expert pro tip: shift+right click the file, "Copy As Path", paste into the terminal. -
I like this one but when I tried it, fyi, it pastes the path with quote marks on either end.... which is burdensome

Quotes are accepted in the adb commands. Without them, each space in the path is interpreted as an argument delimiter.
adb some-command C:\Program Files\Some-Program\Main.exe
passes "C:\Program" and "Files\Some-Program\Main.exe" as two different arguments to adb. Surrounding​ it with quotes instead allows adb to use the full path correctly. Common practice with command-line apps, although not universally supported.
It does work with adb/fastboot though, just did it a couple days ago to upgrade my Huawei Watch with the Wear 2.0 OTA that it kept failing to detect was available.

[h910] rooted Oreo stock-based - get fingerprints AND radio working (if one isnt)

Hello everyone, I'm a total noob but I solved a problem which I couldn't find the answer to, so I thought I'd share. Please take care following my noob advice, I'm not responsible for anything which goes wrong with your phone (and if it gets complex, I probably don't have the skills to help)!!
What was my problem?
When I went from Nougat to Oreo, my radio broke (no cell reception). However I had the files from LGUP, so I could flash "fsg" "modem" "modemst1" and "modemst2" in fastboot (as explained here) which did indeed fix my modem problem, giving me back radio and data. However, this also made the fingerprint scanner disappear from my phone's settings menu. As far as I could tell, this wasn't a problem related to encryption (as discussed in AO ROM thread a lot, which is what I'm now running), rather 'twas a problem with the firmware! So I was loving Alpha Omega, but left without fingerprint scanner since radio isn't really optional on a phone.
Solution?
Please remember, I'm a noob and have only done this for my own phone, a h910, I don't know if i will work for you or on other models!!
Basically, I mish-mashed the two modem files from Oreo and Nougat, to get both things working!
Steps I took:
1) Use Linux - I couldn't get the files to open properly in windows, and didn't find a way to write to the image files.
2) Find a stock "modem.img" file from Oreo (i searched on google "stock oreo h910 modem and it came straight up) - I think I am too new on this forum to post outside links so you'll have to search for it.
3) Find a stock modem file from nougat (I used my original LGUP dump file from nougat, renamed to .img) I'm not sure if it is important that this came from your phone or not, if you followed all the instructions on the dirtysanta root guide, you'll have this as part of your LGUP backup.
NOTE: both of these files were 86 Mb (helped me feel confident I'd found the right thing on google)
4) Create backup copies of both, and append ".img" to your LGUP "modem" file. Call the backup of your OREO modem (the one you got off of google) "MyModem.img", just to keep it clear for later.
5) Mount the NOUGAT img first in a terminal (might have to make a mount point first), for me this was like this:
Code:
sudo mkdir /mnt/modemfiles
mount -o loop /path/to/your/nougat-modem-file.img /mnt/modemfiles
You obviously have to put the file path to where you saved your NOUGAT modem image - the one from LGUP!
6) You should now be able to see the nougat modem .img mounted as a disk in "places" on your file explorer. Go there, and copy the contents into a new folder somewhere easy to find (make a folder on your desktop called NougatModem.) There are two folders iniside, one called "image" and one called "verinfo".
7) Now you can un-mount, as we have what we need from it, easiest to do by just right-clicking it in file explorer and select unmount.
8) Next we will mount the image which will become your new (hopefully working!) modem, but it has to be writeable, so using the same mount point we would do
Code:
sudo mount -o loop,rw /path/to/MyModem.img /mnt/modemfiles
Remember that "MyModem.img" should be your backup OREO image - where all the firmware works but you don't get radio.
9) Now basically comes replacing a few files in the OREO modem (which we have mounted) with ones from your original NOUGAT backup (which are in that folder on your desktop). I couldn't remember if cp command replaced things with the same name, so I used rm to remove files, and then cp to replace them once they were gone.
a) first it is the folder called modem_pr, inside image
Code:
sudo rm -R /mnt/modemfiles/image/modem_pr/
b)next were all the files in the image directory which were modem.SOMETHING
Code:
sudo rm /mnt/modemfiles/image/modem.*
10) Finally we have to replace those files and the folder with the same things from our NOUGAT folder which is on our desktop, using the copy command. I will put the commands as if you did name that folder NougatModem
a) so first the folder which we removed
Code:
sudo cp -r ~/Desktop/NougatModem/image/modem_pr/ /mnt/modemfiles/image/
b) now all the files again, using the wildcard for the different extensions
Code:
sudo cp ~/Desktop/NougatModem/image/modem.* /mnt/modemfiles/image/
So if all went to plan, you now have an image (which you can unmount), called MyModem.img, which you can flash in fastboot to the modem parition (fastboot flash modem /path/to/MyModem.img) and if it works for you like it did for me, you have cell reception, data (after putting in APN if it's needed) and fingerprint scanner all working on OREO. Again, I'm on Alpha Omega, loving the rom and now going to go play a bit.
I've not been on the forum long, but have just gained a HUGE insight into how much time people put into making guides and helping others learn (this has taken me ages haha). Thanks to everyone for your hard work and community spirit, please let me know if this works for you or if it provides any interesting insight as I really did it blind (I had no idea if it would work, and was just making some slightly educated guesses - I got lucky!). Also, if the instructions are hard to follow and you have a hint, I'm happy to edit them to make them clearer.
ENJOY!!
PS - I know the linux commands could be better haha, using more than one mount point too might have been easier, but I figured that I'd just keep it exactly the same as how I did it since I'm a noob and would be more likely to screw something up in the instructions, if I changed it without trying at the same time!
EDIT: I could also upload my "patched" modem image, but not sure if it will work for other people's phones, or if it has "personal" or unique info in it (basically if it would be safe to do so) - If someone who knows tells me it'd be good to go, I'm happy to share it if it would save people from having to go through the whole process. I guess I hope posting all this will be a learning thing for others too Gotta have some justification haha!!

You are to be commended on your well presented write up. But I'm sure there is an easier way to get data and fingerprint working without going through all of that.
I don't have an original H910 device but I did flash H910 oreo kdz on my device and data did not work at all. Didn't test fingerprint. All I did was flash modem using lgup patched from another variant and that solved it.

Thank you for the commendation haha! What a mission!
So I'm guessing you flashed a different version's KDZ?? As far as I'm aware from lots of reading here on xda, there are no KDZ files for the h910. For me the kdz from h915 worked perfectly for example, apart from data. And that was the story with a few things I flashed, KDZ or ZIPs, they would break data, I'd flash the modem, and that would break the fingerprint scanner. Hence this long-winded solution lol.
If you have an original h910 kdz that people don't know about that'd be interesting in itself!!

No, I flashed a H910 ZIP that someone kindly uploaded here somewhere. Then I flashed back the modem from a Verizon kdz.

You are the best, I have been trying to solve this for a long time, I tried flashing many things it thanks to you I now have a working fingerprint and data. Although I am a complete noob for using linux I just used it for the first time using live boot. This is a challenge for noobs but worth it at the end and big thanks.

Why not just cross flash to us996 and walk away? 0_o You get a newer modem this way. I think you have to enable bands on some devices but on h910 I don't think even this matters. You are just downgrading the modem and keeping the new bootstrap. Still from what I read this is encryption issue. There was a supposedly a rsa key change during the update... without them matching the bootstrap will not will not load fingerprint software as it's not trusted unless it matches.

So should I flash the whole ROM or just the modem of us996 to have both working?

Just wanted to say that made my day when I read that the original post had helped you out Cheers for letting me know

Awesome!! Thanks for this. Where did you get the idea of what files to change? Just curious.
I am still tinkering. I have an LGUP dump from:
ATT Stock
A-O Nougat install
A-O Oreo install
I was mix and matching the modem files with various modemst1 and modemst2 files. I did this because it seemed that I got better signal strength with the A-O Nougat install... but I got the kernel panic/modem crash whenever I lost signal on the phone. But with this hand made modem file - no crash. But now I am going to continue mix/match and see what crashes and what gives the best signal strength.
Anyway thanks a bunch!!

Please give me the patched modem file, please send it to [email protected]

I would root then try activity launcher or some sort if hidden menu launcher to get band menu. Alternatively get Network signal guru and lock bands. That how i did it in los 17.1 not sure if it would work on stock. I went from hspa to lte doing it in h915(it's a Canadian h910). I even crossflashed to us996 and left it that way. Says it even says band 66 was unlocked in the app but it has not been tested yet. Either way I got band 4 and 12 once I did this.

Will the current root method used on C432e7r1p8(patch03) allow install font apps?

I'm fairly reluctant to root the phone. I have had an excellent resource on here pretty much warn me against that.
I really want to put a different font on the phone. That's really the only reason I interest in rooting. I'm not wanting it just to be more decorative...I find the bold font hard to read in whatever app may be presenting bold text.
So anyway, l'd hate to do the root (which I understand is not really a full root), and then find it doesn't allow me to install the new fonts anyway.

Rooting is 'full', just that technology (Android 9/10) is changing.
For AdAway app you must enable Systemless hosts (option/module in Magisk Manager), for modules Magisc automatically handles symlinking to the read-only System
So, even from root explorer (sugested MiXPlorer), you see as if AdAway wrote directly to the file system/etc/hosts, or that BusyBox tools are applied directly to system/xbin
Since EMUI 8, Huawei replaced Boot with Ramdisk, and since EMUI 9.1 Ramdisk is also read-only, hence Magisk must patch to Recovery instead
Because of that, you cannot have TWRP if you go for root (don't consider an alternative solution to flash TWRP over erecovery). But formally speaking, TWRP is not part of root (on the old systems, you could have TWRP without root, vice versa, or both). Even with TWRP, TWRP could not change read-only System, and it cannot see dynamical linking active only when system is running (Magisk running). Plus, because of new encryption since EMUI 8, TWRP cannot handle Internal storage (don't consider alternative solution to completely wipe Internal storage and format it without encryption)
All together, from system, systemless works fully seemlessly (as 'full' root). Just you don't use TWRP
To root:
- Install Huawei UpdateExtractor (PC), download update.zip for your 9.1.0.252 c432 from FirmwareFinder, unzip and extract Recovery_Ramdisk.img
- Copy Recovery_Ramdisk.img to the phone, install Magisk Manager, choose Install and then Patch a file, check all three options Preserve AVB, Preserve encryption, Recovery file
- Copy patched_boot.img (rename to patched_recovery.img or so) to PC and flash from Fastboot to Recovery (similar like flashing TWRP) - of course, Bootloader must be unlocked (you have code) and OEM/FRP must be unlocked
- You must boot to system through recovery (because Magisk was patched to recovery), if Magisk Manager shows rooted, you are done
To unroot:
- In case of bootloop or anything: just flash stock Recovery_Ramdisk.img back to Recovery, and you are back to stock
- Regular unrooting: take Uninstall from Magisk (and later, optionally, flash stock recovery_ramdisk.img)
- In case of OTA: unroot (regularly, as above), accept OTA, root again
Btw, you could update your sig now (no more EMUI 5)

Thanks for all the info.
One thing I did not understand from that: will rooting then allow me to add different fonts?
Thanks for the reminder on the sig. I've been thinking of it but procrastinating...which means I would ultimately forget.

Font size can be changed in Settings /Display
I never changed system fonts but there are Magisk modules to do so, search by Google, eg:

Maybe I just am having a mental block...I can't find the firmware in FF. I searched on each of these as criteria:
MHA-L129C432
MHA-L129C432E7R1P8
9.1.0.252
9.1.0.252 c432
MHAJ-L129C432 9.1.0.252
None of those searches found a FW for L129 for the 9.1.0.252 version. I did see a lot for MHA-LGRP2.
I used FF on the phone. I downloaded FF for the PC, and can't figure out how to use it. I put a model in on the Main Page, nothing happens. I see no way to put a model in on the Search Firmwares page.
Of course, I was updated to 9.1 via OTA, so all the work I did getting to 9.1 did not involve downloading the firmware to my PC, so I don't have it from all that work.

Look for MHA-LGRP2-OVS - see screenshots.
You can also find through Web:
https://pro-teammt.ru/firmware-database/?firmware_model=MHA-LGRP2-OVS
Btw, there are several b252 packages there, all the same size (and probably all ok) but I was told that package number #279403
is the one that is distributed by OTA

Thanks.
I saw the MHA-LGRP2-OVS ones, but I thought I needed to find one with identical name to the one I'm on.
This stuff doesn't make much sense...at least not logical. Only experience and/or help makes it possible to get it done.
Appreciate y our help.

Well, I don't know what's going on. I downloaded the FW from the link you provided, as well as from FF on the phone.
The one from the phone, once I transferred it to the PC, wouldn't extract anything from the zip.
The one from the link extracted, but when I loaded the Update.app into Update EXtractor, I got this error:
So, I then downloaded a different version from the web site (282444), and got this in Update Extracter:
Maybe it's warning me to not root:silly:
I am going through the thread about the extracter tool now to see if I find anything helpful. First blush looks like I'd need to make a profile file that is outside the limits of my knowledge. We'll see.

OMG - I think Im writing you THIRD or FOURTH time that the same unlock code you obtained will still work!!!
Because the code is bound to the serial number of your phone and will work for unlocking/relocking for the lifetime of your phone
Huawei is just making harder and harder to obtain the code (in the old days Huawei was giving the codes immediately and for free through their own page, now with the new EMUI versions it is needed to physically open the phone and use Testpoints and code providers charge you 30 Euros or more) but once you have a code (no matter when and how you obtained) , you can use the code the same way as always (fastboot oem unlock/relock ...)

OMG, yes, you have. BUT the site that provided the method to do it says it won't, per the quote I put in my post. I'm inclined to believe you, you have been a very good source and patient. But, I was wondering why would they say it won't work? That is their exact words, about their tool.
That being said, I guess as that I had the code before upgrading to 9, then just following the fastboot commands with that code will work, and in fact doesn't even use their tool. . So, I'll continue with that then. The information out here can sure be confusing.
Thanks...
[EDIT]
I figured that likely it would be the ramdisk.img file, and through Google search I found a thread that verified that. So, I'm continuing on.
Thanks...

Here's an interesting thing.
After patching the file, and seeing the instructions here, I find that the file they referenced in Downloads is a different size from the one I selected to patch, which was the RECOVERY_RAMDIS.img.
Do you think that indicates a problem? I presume I should use the one I selected, which was your instructions, but wonder if maybe something went wrong with the patch.
Again, just being cautious.
Thanks for your help.

So, are you the same as previously, @ewingr?
If so, have you successfully unlocked Bootloader with that old code
OpenKirin instruct to patch Ramdisk and that was correct for EMUI 8.
(If) yu are on EMUI 9.1, hence you need to patch and flash Recovery Ramdisk
When patching from Magisk Manager (MM), you have to check all three options: Preserve AVB 2.0 DM-Verity, Preserve Force Encryption and Recovery Mode.
Does MM report any error while flashing or success/ok?
You can rename patched_boot.img to like patched_recovery.img, doesn't matter, but you must flash it to Recovery (like flashing TWRP to Recovery).
Right after flashing, boot by key combo to that patched Recovery (like booting to TWRP by key combo, after flashing TWRP).
Of course, you will not flash/use TWRP here

I don't imagine you'll find this hard to believe, but I got an error on the flash attempt
I renamed the patched file to: Patched_RECOVERY_RAMDIS.img

Again, if you are on EMUI 9.1, forget Open Kirin instructions (for EMUI 8).
You must patch Recovery Ramdisk and flash to Recovery Ramdisk, so:
fastboot flash recovery_ramdisk Patched_RECOVERY_RAMDIS.img

I did in fact not use anything from the OpenKirin. But I apparently used wrong syntax for the command. But you providing that will help.
.......
It didn't work at first pass. I think this is why.
You will recall that in the discussion I had about the OpenKirin instructions that I mentioned they referenced a patched file in Downloads. Well, stepping through it again, and reading the small print, it says "Patched file is in downloads". So, it did not update the file I had put there, it used that to create a new patched file that was saved in downloads.
So, I will not go ahead and download that one and continue with the instructions. I bet it works this time.

I think I have success. But of course, a couple interesting things:
So, you indicated I need to "boot through recovery". So I expected to hold power, and vol-up to boot into recover. But it booted to the phone.
I got a request to grant Superuser to Tasker, which I did.
I loaded Magisk, and it says it is installed, but doesn't have any indication if it is rooted. I presume it is, given the request for Superuser for Tasker.
Just now had it pop up with a notice that there is an important system update patch. I don't know if I can stop it, or if I should care about it. I did say "later" so for now, it is not installing.
One other question: Is the method to have root accomplished in the future by booting with Power+Vol-UP? If not done that way, it boots non-rooted? (I ask because it did get booted up w/o holding pwer+vol-up, and it did not show Magisk installed. After that was when I booted with the key sequence.

Magisk by default means you have root. You can install and disable modules in Magisk Manager, but you cannot disable root - for that you must Unistall Magisk (an option in Magisk Manager).
In MM you have a tab/menu showing all apps that were granted root - you can suspend or even revoke to some
Check in Settings/About, does it show you have b252 or b252 Patch03. I think that it thinks you are on b252 without Patch03, and it wants to install that patch.
But I don't know would you loose Magisk if you accept (or even get bootloop), so better disable authomatic OTA updates for now.
Believe me, similar 'Important' patches were receiving users (starting at the same time) with various Huawei phones running EMUI 9.1, discussing on XDA what it was, but there was never an answer, nobody detected any change for something better or worse.
So you don't loose anything if About showing b252 without Patch03
To boot to Magisk you must boot with Vol+ pressed - with USB discinnected.
If connected by USB to charger or PC, booting with Vol+ pressed will boot to eRecovery.
Normal booting (without Vol+ pressed) boots to the system (Android), but with Magisk disabled (MM will say that Magisk is not installed), so no root.
Reboot again with Vol+ and you are again rooted
If it ever comes an OTA for higher than b252, you will have to Uninstall Magisk from Magisk Manager and then accept OTA (and root by yhe same procedure one more time, with recovery_ramdisk.img from the new firmware).

Anomoly with root...
Root is working, albeit with anomalies.
If I boot w/o going through the recovery/Magisk, the phone boots up w/o root, and all works fine. When I go through recovery/Magisk, it comes up rooted, but with the following untenable anomalies: Dialer/Phone does not load; Contacts are not available; As result calls I receive do not show who is calling, and I cannot make calls out.
Given that changing fonts do not give me the fix I was chasing (see this thread), I may, unroot. But given that I can boot up w/o root and it works fine, I'll hold off un-rooting for a bit.

[GUIDE] Enabling LTE on China Telecom (and others) on Pixel 3 XL (Android 10)

Being a huge fan of the Pixel series and living in China is not easy. Just upgraded my XL to 3 XL and naturally I had to enable the LTE to work in China. Regardless what you may see on the Chinese forums (gfan), all the files you need are already present on the phone.
Files you need:
1) The ADB bridge for Windows
2) The most recent factory image
3) Magisk Manager
4) Chinese-Carrier-Pixel-3-xl-LTE-VoLTE-Enabler (Magisk Manager module) - Github direct: https://github.com/wangdaning/Chinese-Carrier-Pixel-3-xl-LTE-VoLTE-Enabler (big thank you to wangdaning for allowing me to publish it.) Also attached as a zip file to this post.
If you don't understand what these files are for or where to find them, perhaps you should ask a friend to help you. Flashing anything wrong could result in an expensive brick. Always backup your data, never blindly trust a post, and do your research. This post is in good faith and I am not liable for your actions.
Now, I don't have any of the variants of 3 (Pixel 3, 3a, 3a XL) but I would assume it would work in a similar fashion; however, see above and do your research. Check file structures, read some posts, backup data, etc. If someone does try it, please report both success and failure to build the knowledge.
1) We need to ensure our phone has an unlocked bootloader. If your bootloader is locked, you WILL lose all your data. Ensure you backup everything you want to keep. There is no getting around this step. We need to be a developer first. Go to Setting->About Phone->Build number (tap it until it says you are a developer). Then go to System-> Developer options -> OEM unlocking: turn it on. Next we need to reboot to the bootloader by resetting the phone and hold the down volume key as it reboots. In the bootloader, first use the volume keys to find and select the unlock the bootloader command with the power key. Then, we need to send the following command:
Code:
fastboot flashing unlock
You will receive a wipe and security warning. Accept and reboot the phone. It will wipe and reset your phone to factory.
2) I started from a stock image (May update; QQ2A.200501.001.B2). I suggest you start from there.
3) While we have the May update in front of us, we need to extract the boot.img so it can be patched to root the phone. TWRP doesn't support us at the time of writing on Android 10. (Hope that new baby is healthy!) The boot image can be found in the zip image-crosshatch-*release code*.zip/boot.img. Transfer this boot.img to the phone to be modded to enable root.
4) Next the phone needs to be rooted. You need to download the most recent version of Magisk Manager. Once installed, open up Magisk Manager. It will report no Magisk and that's ok, we are installing it now.
5) Tap install on Magisk and it will ask if you want to install, so install. Then you need to select the method. We will choose "Select and patch a file." Tell it where you saved your boot.img and it will patch it to allow us to root the phone. The output file we need is called magisk_patched.img is on the phone. Move it back to your directory with your ADB bridge.
6) Next we need to flash this patched boot file to our phone to complete the rooting process. Reboot to the bootloader and send the two commands:
Code:
fastboot flash boot_a magisk_patched.img
fastboot flash boot_b magisk_patched.img
Reboot the phone and congrats, you are rooted with an unlocked bootloader.
7) To prepare for the install of the mock files that will point to the files on the phone, we need to delete a few checking files. Using your file explorer of choice that can gain root access delete the following:
/data/vendor/modem_fdr/fdr_check
everything in /data/vendor/radio/ (make the target folder empty)
8) Download the LTE_enabler from Github or the zip file here. Open Magisk Manager and open the menu -> Modules -> "Yellow Plus" to add. Point it to the zip file.
9) Reboot and enjoy using your phone as intended.
I tried to be as detailed as I could but not be over verbose either. If any step is unclear, there are more detailed guides on this forum concerning bootloader unlocking and Magisk rooting on Android 10. As a bonus tip, does the "x" showing no data bother you and stop some services from working? If so, this can be fixed by re-pointing your captive portal to something inside the firewall. This can be accomplished with one line of code:
Code:
adb shell "settings put global captive_portal_https_url https://developers.google.cn/generate_204"
Enjoy and if you have questions about Pixel and China, feel free to post them. Support right to repair!

I downloaded the zip file but it tells me it's not a module.

Could use more details, otherwise it is hard to help. It definitely is a module and installs fine. Something else is going on.

is this for china only? I have a Canadian 3 XL and moved to Bucharest, need to enable VOLTE on Orange Romania. I'm also on Android 11

It should work, but you would have to slightly modify the files. Instead of pointing to the Chinese carrier modem file you would want to point to the orange Romania file. I looked and there is an mbn file for orange Romania, it is just not included in the mbn_sw.txt. Then again, have you made sure Orange has activated VOLTE for your device?

I contacted Orange and they say VOLTE should be working, that the issue is my device not being compatible with their network. I also bought a Samsung watch 3 with LTE and can't activate LTE through my phone, i assume it's due to the same issue.
I'll follow your guide and report back.
Should be no issue if i am using Android 11 instead of 10 right?

Should be fine, you just need to make sure that you modify the mbn_sw.txt file to include the location of the Orange Romania mbn file. You might just try this first:

If that does not work then you need to modify the module to include the romania mbn.

Dude i love you! worked perfectly. I followed the guide to root Pixel 3 on Android 11 and then your steps, didn't modify anything and now i have VOLTE enabled!
thank you so much!

ok i spoke too fast, while VOLTE is enabled now in the settings, when i make a call, it switches to H+ which means its not using VOLTE. any idea? I modified the .txt file to include the location of the romania .mbn file, i modified the file directly on the phone though, after installing the module with magisk manager

Not sure, to many variables at play. I mean it could be that orange Romania only has VoLTE in certain areas/cases. Try using *#*#4636#*#* and phone information, see what it says.

I did that, both VOLTE and Wifi calling say provisioned. I guess it might be something on Orange's end.
I saw a reddit post for a Pixel 3 having the same issue and the carrier ended up doing something on their side.

Confirmed working on Pixel 3 w/ Android 11!

Can this patch work on Pixel 4 as well? Thank you

You would have to find the location of the files on the Pixel 4 as I am not sure where they are. Then modify the module to point to the correct location.

Question I can receive text messages, I cannot send them

**SOLVED - I restared the phone and everything works as it should. Follow trouble shooting lesson #1 - Unplug and plug it back in**
I'm looking for help to troubleshoot my text messaging after using ADB to uninstall some packages.
The phone is a Oneplus 9 from Tmobile, and I have a verizon account/SIM card. My original intention was to completely delete the bloatware / unused applications from my phone but the script I was running (Tomatot's script) is not updated for Android 11 and I ended up abandoning that route and instead just used the ADB commands to uninstall. As such, I did unlock the bootloader, installed TWRP, and used TWRP to run a version of the Tomatot script. I noted nothing changed, and did not try to revert or undo the Tomatot script.
I then went to ADB commands and uninstalled the below list of packages:
package:com.oneplus.calculatorpackage:com.android.cts.priv.ctsshimpackage:com.oneplus.gamespacepackage:com.sprint.ecidpackage:com.google.android.cellbroadcastservicepackage:com.sprint.w.installerpackage:cn.oneplus.photospackage:com.tmobile.m1package:com.qualcomm.uimremoteclientpackage:com.oneplus.brickmodepackage:com.netflix.partner.activationpackage:com.tmobile.pr.mytmobilepackage:com.oneplus.factorymode.specialtestpackage:com.google.ar.corepackage:com.oneplus.android.cellbroadcast.overlaypackage:com.google.android.marvin.talkbackpackage:com.oneplus.factorymodepackage:com.android.eggpackage:com.google.android.apps.tachyonpackage:com.sprint.ms.cdmpackage:net.oneplus.pushpackage:com.android.dreams.basicpackage:com.google.android.apps.wellbeingpackage:com.tmobile.pr.adaptpackage:com.android.bipspackage:com.android.cellbroadcastreceiverpackage:cn.oneplus.oemtcmapackage:com.oneplus.filemanagerpackage:com.google.android.ttspackage:com.sprint.ce.updaterpackage:com.google.android.videospackage:com.oneplus.faceunlockpackage:com.google.android.feedbackpackage:com.oneplus.opbugreportlitepackage:com.tmobile.rsuadapter.qualcommpackage:com.oneplus.screenrecordpackage:com.android.providers.partnerbookmarkspackage:com.android.wallpaper.livepickerpackage:com.oneplus.bttestmodepackage:net.oneplus.commonlogtoolpackage:com.android.bookmarkproviderpackage:com.android.cts.ctsshimpackage:com.android.wallpaperbackuppackage:com.sprint.ms.smf.servicespackage:com.google.android.apps.youtube.musicpackage:com.android.traceurpackage:com.google.android.cellbroadcastreceiverpackage:com.tmobile.rsuapppackage:com.tmobile.rsusrvpackage:com.android.cellbroadcastreceiver.overlay.common
Can anyone here take a look at my uninstalled packages and easily tell which one is related to text messaging? I would hope to easily find the one or two from this list instead of re-enabling each one and see if texting is restored.
At this point my options are - start enabling packages via ADB commands to see if texting is fixed, or factory reset -> verify texting and other functionality works -> use ADB to uninstall packages and test texting/other functions after each package.
Thanks for any help in advance!
(I did find a thread about using Magisk Debloater to remove bloat and will look into that method since the Tomatot script with TWRP did not work for me. First I need to fix texting or my wife will kill me)

You def removed brickmode and unsure if you can still connect through edl to msm tool. Btw this would be your only option is to restore everything with msm tool for your variant. Or fastboot flash whatever build your on back to device.

Thank you for the response. Brickmode, as far as I can tell from internet searching, is related to Oneplus's 'Zen Mode' which I do not need or want. If I am mistaken please point me to a discussion about this particular package so I can reinstall it if its required for recovering from bricking a phone. I think its a deceptively named package.
I started re-enabling the packages above and after a phone restart all my texts came back. I then un-installed the packages one by one and none of them affect texting. Soooo I think it was the phone restart that fixed it. As always, turn it off and back on first to see if that fixes the problem.
