V40 is it possible to change NT Code without Root? - LG V40 Questions & Answers

I have read through many posts here in the forum, where I got some tips that I have tried, but nothing that totally applied to my problem, only parts of it. I have upgraded my phone with every firmware of the Open_EU since January 2020 without any problem using LGUP. Last time I upgraded to Android 10 in August, it was also successful but then check nt-code: 222201: ff started to appear everytime I turned on the phone. It's annoying, but not a big problem since the phone works perfect. However I tried to upgrade to Android 10 v405ebw30c recently, and now LGUP can't make the upgrade, it says can't cross-DL, with a strange message judypn_lao_eea ->judypn_lao_com. Could the NT-code be the cause of this? I also tried to enter the hidden menu, *#546368#*405# and I can see the nt code, but I can't change it. Nothing happens. Will I have to root my phone to make this work? or are there other options?
Some history, this phone doesn't officially exist in Sweden, where I live. However, it's possible to buy it anyway. It was sold as brand new and unlocked. The first week I discovered that I couldn't make the officially update . Then I found out it's originally italian (TIM), and probably someone that unlocked afterwards. But maybe not properly made since it was problem to make upgrades with LG Bridge. And when I succefully managed to make the upgrade with LGUP I decided to keep the phone anyway, because I liked it too much. But since this NT code started to appear after the Android 10 upgrade, I wondered if maybe there's some "leftovers" from TIM italy. So is rooting the only option for me? Except for the upgrade problems it works perfect every day.

Thank you for your reply. Yes, I have read many instructions even on this page how to edit, cust_path_mapping.cfg, and that it's surely easy once the phone is rooted. But that's why I first wanted to see the possibilities to do this without that I have to root the phone.

So, u have 2 problems right? u want to upgrade to v405ebw30c, but can't, and you also have the nt-code error right?
First, no, they aren't related. I think that's highly unlikely. That's not something lgup checks for. I'd bet you're using the 1.14 version dll and should be using the 1.16 dll and should be doing a refurbish.
As far as the nt-code error. It's a pain, lots and lots of info about fixing it, most of them need root. But here's what worked for me, no root needed: I switched from att pie to Korean open Q (first time had the nt-error and no editing anything would fix it), so went back to att and then did the korean 409N again, first with partition DL. Let that finish, it has to reboot the phone completely to finish. Then, don't change the phone in anyway, just shut it off. Back to LGUP and do a Refurbish with the same kdz.
No more nt-error code. It *seems* that nt-error code info gets propagated to various partitions as a part of refurbish. I verified that the ftm partition, where that information lives, was completely spaces (blank) after the refurbish... it's odd, I know. But for whatever reason, I no longer have the nt-error code problem.
cheers

Thank you for your reply. No I don't know if they're related either, it was just a guess since the problems started at the same time. Well, I always had a kind of "problem" since I never have been able to upgrade from LG Bridge. And that I guess is from the NT-code. But the sign in the start appeared after the Android 10 upgrade. However, I'm using LGUP 1.16.0.3 and I have used it everytime, with DLL version 1.9.39.7.
And actually it wouldn't bother me too much having this sign in the start anyway, I only restart the phone like once per week. But of course it bothers me that I can't make the upgrade like before. And I can also mention that I have never tried to refurbish with LGUP, only upgrades, because I have some bank apps etc. that are a bit complicated to reinstall. Of course it's possible, but I have to be mentally prepared for it. So I'll only do that when I know there's no other option. And the phone work good today, so I'm not in a rush, but in a couple of months I should be doing an upgrade of course.
And thanks for telling me the other option too, I will surely try it one day but since it also requires refurbish I will try after I fail to make the normal refurbish.
I don't have any experience of rooting, if I root my phone, will I keep all the data or is it comparable to refurbish? Are the any other risks rooting the phone? I'll lose the warranty, but I don't really have the warranty anyway since it's not an official product in my country.

No, to root, you loose all data and have to start again. Part of rooting is to flash dm-verity which turns off encryption. But, that allows you to do a backup of the data partition once you've reinstalled everything. The positive side there is that in the future, you could back up that partition (data), make any other changes, then flash data back, and your apps would be back as they were.
Other risks? Well, maybe, if the phone was stolen I guess, it would be easier for someone to steal your data. Your situation, with serious banking apps, it **may be** you don't want that risk...
Maybe for just trying a refurb to lose nt-code, look at LG's 'restore' from previous device ability, use it to save off the apps somewhere, then restore after refurb? no root needed.
cheers

LG 4xHD not registered

I have just managed to root my old LG P880/4xHD using advice from this forum. Thought I would try on an old phone first. One reason I tried is because I cannot update Android via the usual About phone, Software updates, Check now for updates. The Android version installed is 4.0.3. I am in Australia and it is possible the phone is an overseas model (got it from a friend in LG). Has "Not for Resale" stamped inside the back cover. When I try to update Android, I get an error message "Registered Error - Your device is not registered yet." I had hoped rooting would get around this but it hasn't. Have looked up old forum posts and there is talk of using .kdz files and all sorts of other things. Can anyone help me get around this registration issue but please be aware I am a novice and most of the older posts I read, I couldn't understand so simple explanations please. Thanks.
What you have is developer or test device and it is a bit different from normal ones. Try googling more but you will have hard time....

Could it be that it has overseas firmware, I read in a two or three year old post that this can happen but there was a way to get around this.

Its a year old phone, its not like its the nexus one or samsng galaxy s2...
Try flashing 4.12 with kdz. Google is your friend, try kdz flash 4.1.2 Optimus 4x hd.
Funny thing, when I bought my phone, only google asked me to register the phone, the usual Google Play thing. SO what do you exactly mean with REGISTER?
i think the whole phone isn't registred by LG for consumers, like dimi89 said it has to be a dev device. they aren't registred and cannot be updated/used the normal way. the serial number of this phone isn't present in the LG databases i think. Just flash kdz and everything is fine. You know that you don't get any support or warranty on that phone but you should know that.

Factory reset - Problem.

Greetings everyone!
Few weeks ago, I gave my device to a friend of mine to manually update it. Something went wrong so he decided not to go any further. Yday i tried to "Factory reset", after reset some error pop'd in the left upper corner of the phone.It says:
[LGE_SECURITY] ERROR: boot image signature
Critical failure: Unable to start kernel.
Unrecoverable bootloader error (0x00000002).
Anyone had any similiar or even the same problem as i am facing right now? Thanks in advance.
best regards, Milan
Guy didn't know what he was doing apparently. Your handset is still locked and he apparently tried installing a 3rd party ROM, lemme guess, you wanted a newer version of Android than 4.1., which is a reasonable enough thing. Problem is that out of the box you can't do that because it only boots images signed by LG and they abandoned development after releasing 4.1 and a couple of minor point releases. You aren't totally screwed but if you were having somebody else do it for you, you might need to get some help. You can find the details elsewhere here, or more likely point a more skilled friend at it, but here it is in a nutshell.
You need to get LG's official updating software (from the LG website) and you need to fiddle with it a bit until you get it to do a rescue because it expects to have already paired up with the phone while it was still working. If you already had it installed, great because it will make it easier. Anyway, you will probably have to manually pick your model and input the IMEI since it won't already know those things and it will go out and fetch the most recent image. You will push VOL Down and insert the USB cable from a powered down state, it will then do the rest. Good chance you will even retain your data unless that 'factory reset' you mention actually succeeded.
Of course that will only get you back to stock 4.1. Read around for the official way and several un-official ways to unlock your boot loader. Once that is done you can install a better recovery and then a newer version of Android. But the first step is to restore the stock software since you have to have a running phone to be able to unlock it.
And no, nobody has ever been able to explain WHY they lock them, but every single manufacturer seems determined to do it, chipmakers put a lot of work and ad copy into how extensive and unbreakable the locks on their newest chip is, etc. And then they either bow to customer demand and add an unlock feature or we here at xda do it for them... as a courtesy of course. Truly we do live in the asylum. Wonko the Sane was onto something.

Upgrade path from B123

I'm running a P7 with the firmware it shipped with and I'd really like to get it up to date, but every package I've tried so far has failed during package verification. There seems to be very little info on how to update your phone from such an old build. Can anyone please help because I'm at my wit's end here. I have a limited date cap so can't just keep downloading updates in the hopes that one of them will work.
I would be greatly indebted to anyone who could help me. This issue is making me want to cry.
Do you have a phone with a provider/network lock? Which roms did you try so far? You may give B133 a shot, if that doesn't work you'd have to go the way over a custom rom and then getting back to the stock one. I can describe the process more detailed in case it's necessary.
Thanks for the response!
I think the issue is that it is a network locked ROM. I got the phone from a provider called Vodacom and get their splash screen and everything. I went to speak to them and they told me I'm not supposed to be able to update my firmware because that requires rooting the phone, which voids my warranty. Sales people being sales people, I'm not sure how truthful this is. I can't imagine a provider refusing to let you update your phone.
So far I've tried B133, B609, B617 and B853, none of which works, sadly. Someone suggested I unlock the bootloader and I got the unlock code through the Huawei site, but when I try to boot using the three-button method it tells me that no update.app file was found, so I'm not sure how to get to where I enter the unlock code.
Hm, you might search around a bit and find an easier way, but if not, unlock the bootloader, flash twrp and any emui 2.3 based custom rom. Then flash the stock recovery and make a forced update (3 buttons) with B133.
To access the bootloader you have to press volume- and power until a white screen with some text appears.
Anyway, to update would definitely be worth it.
Yeah, I did precisely that last night and ended up soft-bricking my phone. It wouldn't even work when I flashed the original firmware. It's currently in at a repair shop and I hope they can fix it. Lesson learned though.
Thanks for the help anyway.
It's not that easy to hardbrick the P7, it's very likely that he will be able to fix it! With some time for trying, you probably would have been able to do it by yourself, too.
Your very welcome
Yeah, the thing is I was up all night trying to fix it. Flashing it back the original software should theoretically have done it, so I have no idea why it didn't.

VIE-L09 seems to be totally screwed!

Hey,
So i used the SRK tool to try and root my VIE-L09C40 (P9 Plus)
Something seemed to happended during the rooting procedure and when i entered e-recovery it said it had to Download a new version, but couldnt connect to internet via wifi.
Any ways it seemed to work after a while but now i have no keyboard at all, so i cant literally start my phone.
it starts, boots the EMUI 5.0 logo and goes through the information a terms, i click the ok button and thats fine.
Next it tells me to sign in to my wifi, i select my wifi and when i go to type the password all i have is google voice as a keyboard, ive searched and searched but cannot find a way around it, also the frp has tripped on phone so i cannot log in to my google account without a keyboard.
How can i get around this?
do i have to flash parts of firmware?
any help would be great, i sent it away to hauwei and they say warranty void due to software!, can only assume something wrong was flashed?
Waiting for phone to be returned now, please help
I had the exact same issue last night as well. No keyboard and only an option to enter details with voice.
Ended up with an essentially bricked phone. Couldn't find any info on the problem online, so I have to improvise.
I'm starting from scratch after formatting etc. using stock oeminfo, recovery and rolling back to Marshmallow. (fingers crossed ADB will let me, because it was giving me errors before)
Will let you know if I'm successful and the steps I took.

Good luck, i did read that it might be possible to install the base firmware back to it and then update again.
Im sure we are not the only people this has happened to and if you succesfully do this, maybe consider making a full step by step guide so to help others.
Fingers crossed
:good:
Will do my best.. So far it's been a major. I've managed to flash a working stock ROM and boot up. But there are a few things to smooth out. Such as, I have no IMEI number now and the build is C900, also the bootloader is modified.
To get it to boot I had to use DC- Phoenix to flash a factory firmware(Chinese) which I had to pay for. Then I flashed a stock vie-l09c432b181 ROM over the top.
To repair the IMEI I'll have to use HCU, which I'll have to pay for as well. But that's ok. If I can get my original IMEI back, I can use the original unlock code I got earlier this year, otherwise I'll have to get a new one based on a new IMEI.
I can repair the bootloader and region code using twrp etc. so that's not a problem.
I'm actually using the phone to write his reply, so I can at least use it.
Once I have it all 100% working I'll try to put together a full step by step.
Cheers.
Well, I have a working phone. But, it'snot stable. Having trouble with mobile connection, sms, mms, 4g etc not staying connected. So wont be doing any write-ups just yet.
Not until it's stable.
I'm wanting to return it to complete stock now. And that requires trying to find an oeminfo file for C706 (New Zealand).
Will add more as I get there. Sorry.
I had the same problems. All I did is updated the phone with the firmware you want via Twrp . Be warned that it will replace the recovery back to stock. Also clear the cache and etc.
I had a similar issue with SRK tool, bootlooping, won't flash new firmwares, lost all the stock apps and diagnostic tools.
I'm now stuck on a TEST-KEYS build with no NFC or Bluetooth.
My solution was to throw the piece of junk in a drawer, forget about it and I went and bought a Pixel XL instead - a phone that is properly supported and gets updates quickly.
After much messing and a headache I finally got to c432b370
And everything back to normal

How did you succeed?
I am stuck on TEST-KEYS but I am not able to flash other roms on it. When I go to recovery, the update process stops after a while

How To Guide FYI: NE2217 T-mobile (Carrier locked, BL locked) <== Dont Flash Any Other Region w/o reading.

!!! This is a HIGH RISK method of performing any form of modification, if you are on a T-Mobile ne2217 !!!
There are unidentified files that your device might have conflict with, and cause a bootloop!
Proceed at your own risk! You have been warned!​
OK, first lemme explain. The NE2217 (10 pro) itself does not have any special restrictions on it, unlike the CPH 2419 (10T) which is an exclusive T-Mobile variant. My guide on region swapping the CPH2419 (10T, link below) is still valid for the NE2217 (US- NA) . But there are conditions required or you will enter an infinite bootloop which becomes un-recoverable, without an edl flash. I do not have the specifics as to exactly which partitions cause this, but basically the bottom line is, IF YOU HAVE NOT UNLOCKED YOUR BOOTLOADER, EVEN IF YOU ARE SIM UNLOCKED, do not attempt to region swap.
There are a couple of partitions that are specially locked, that ONLY become write capable using the fastboot command, "Unlock Critical". Without a Bootloader unlock, the Oxygen Updater/Local Update programs, CANNOT make the needed changes to the Kernel, as well as these other important partitions, which have instructions that implicitly block changing to other regions. I cannot confirm if this exists in other countries with carrier locks, but i do know for a fact that T-Mobile has this enforced on all of the 10 Pro (ne2217) purchased through them.
As mentioned in previous threads that ive replied in, I suspected that the apps Oxygen Updater and Local Update, do not have the permissions capable to make direct changes to the boot.img, or recovery.img directly, primarily because those partitons cannot be altered while the system is currently running. These images can only be altered through Fastboot, or EDL thus the need for an MSM Tool if you cannot unlock your bootloader via conventional methods. So what happens is upon "Pre-boot" those special instructions i spoke of, take authority and put the carrier specific files, into an untouchable state that are locked behind the USERDATA partition, so these applications just copy the updated files to the inactive partition and performs the changes during the next boot, and even a hard wipe factory reset does not have the authority to erase the carrier instructions. The only way they are removed is by Unlocking your Bootloader! When you do that, the Qualcomm Processor has an embedded command, which is required to ERASE the entire Userdata partition, to protect the encrypted files protected by the bootloader lock! You can read about that by googling "Qualcomm Bootloader Unlocking".
Hope that makes sense to the majority of you. So again, the ONLY requirement for you to be able to go from 'ne2217', to any other fw is YOUR BOOTLOADER MUST BE UNLOCKED!
Failure to follow that one requirement will indeed force your device into an unusable, infinite bootloop, which can be resolved only by an EDL flash, which as of right now we do not have the tools that can perform this on CONSUMER level. You will have to RMA, your device, or go thru third party channels, which in itself is very risky, and puts you at risk of viruses/malware/wormholes/zombie-apocalypse because you must give someone full access to your computer remotely, and pray that the person only does what you requested. (NOT IDEAL).
Now if you're on a T-Mobile locked device, you are NOT hopeless... as I am on a T-Mobile locked device, and i am now bootloader unlocked as well! These two conditions are independent of each other, but trust me when i tell you that YOU DO NOT WANT TO GO THRU WHAT I HAVE EXPERIENCED, IN ORDER TO REACH THIS GOAL!
In so I will not publicly disclose how i was able to enter the real Fastboot Mode, so that i could pull the unlock code needed to request the unlock token from T-mobile.
(If you are so inclined to do this that you are willing to forgo ALL precautions and risk the possibility of bricking your device, or you have already landed yourself in an unrecoverable bootloop state, and are willing to try ANYTHING, you can join Bootloopers Anonymous, by clickiing it, and drop a message. This is a brand new telegram channel, and i will try to watch it for your requests. And again i strongly advise that you DO NOT embark on MY adventure, but if Unlocked Bootloader by Any Means Necessary is your ultimate goal, and nothing less is acceptable, i will try to help you achieve it... *** YOUR DEVICE WILL ENTER A COMPLETELY UNUSABLE STATE FOR A MINIMUM OF 7 DAYS!! *** but bear in mind that EVEN IF you have to use my method, you will be still subject to the 7-day waiting period outlined by OnePlus company policy. No one can overcome that, as the unlock token comes thru a separate division of Oppo/Oneplus that only generates the token through an automated request which is pushed after the expiration of 7 full days (1-week) has passed. YOU HAVE BEEN WARNED!)
The 10-Pro doesn't require the "In-Depth Testing" app to get your BL unlocked. That said, it also does not mean that OPPO has not designed one for this device because indeed they have. That application is individually encoded with device specifications so that only devices and regions EXPRESSLY AUTHORIZED by Oppo, can submit a request to unlock. DO NOT TRY sideloading any "In Depth Testing" apk floating around on the internet, as these can be altered to contain malware or worse, and then if your device becomes corrupted by it, Oppo can deny you an RMA on your device, thus charging you for the repair as there are warnings that you must acknowledge to even run the app, and attempting to circumvent the safeguards that this app already has in place is considered a violation of ToS.
If OPPO adds your device/region to the list of allowed devices, you will be able to download this application through OFFICIAL channels, and it will be made known to the public.
Once you are completely knowledgeable that your BL has indeed been fully unlocked, you can proceed to follow the instructions in the link to my guide below. The guide is for the CPH2419 (10T), but the instructions are completely compatible with the 10 Pro entire series, assuming your BL is unlocked. On the 10T this is not a requirement, and i honestly do not understand why this enforcement was put into our 10 Pro model, released almost a year earlier. Probably just an oversight by T-Mobile which might be corrected in future builds.

again, what most ppl are failing to do is follow my guide exactly as i defined. The VERY 1st thing you MUST DO... prior to unlocking the Bootloader... Prior to even downloading ANY rollback packages is, you MUST go and Download ANY of the Android 13 beta updates that are available in Oxygen updater. Turn on advanced mode, and select the whichever model you prefer... Its actually best to choose the region you plan on swapping to, for easier transition with the rollback package. IMHO i would always pick the EU model whenever attempting this, simply because that one usually has more bands available. But the main idea behind this is to make the phone, first BREAK the connection it has with T-Mobile's custom kernel, and modem... which is done just by upgrading to an Android 13 beta, as T-Mobile does not EVER release any beta builds, so by doing an actual OS upgrade, your phone must load the OS kernel, and several other partitions/files which i am sure that T-Mobile has branded in the 2217. Upgrading to a newer OS will without a doubt overwrite the carrier locked files, because the Upgrade comes from a higher authority in the chain of trust. Until TMO releases an update, then this is a requirement so that the rollback package of that region can safely downgrade the files, in their correct partitions. If you download a beta 13 thru oxygen updater, you can local update flash it, without problem. I did it myself to several demo devices at Tmobile stores here in Texas to test the technique, after i bricked mine by using a rollback package first!
Remember the 2217 is a T-Mobile EXCLUSIVE! No other carrier may sell this same model... but ALL of the internals are the exact same, and as im sure we are all well aware of, T-Mobile doesnt have the fastest adaptations when it comes to OS updates.
But there are several key identifiers which point to a custom made BL, Kernel, and Modem: 1. The build for all T-Mobile versions is on a revision that no other model has released... This alone could cause BL because if you flash a build that is older than the one you have currently, several files have anti-downgrade measures built into them. This is why we need the signed rollback packages to downgrade. But even if OPPO signed a rollback, unless they released one with T-Mobiles file specs, then anything you flash can create a conflict with an existing file... BL! But i know of about 13 ppl who have attempted my method, plus i just did another one myself last night for someone who contacted me and offered to compensate me royally if i would meet them since we were local logistically. 2. AFAIK, when installing a different rom to a device, you cannot downgrade the modem version. I know this is apparent with Samsung... as if you try to flash a rom with a lower modem version, it usually bricks, and you have to use odin to flash the newer modem back, in order to boot. Again this is taken care of by installing the NEWEST beta for Android 13, unless you had my situation which is, my phone CAME WITH updated security, and build already installed for October 2022. I havent heard of anyone who has said they even have the option to update theirs past August. So new purchases have to be careful. T-mobile sold mine with a blocked Fastboot, that doesnt respond to the button combo. Which clearly identifies they modified the recovery partition. 3. E-fuses have become a staple in Android devices for the past 5+ years.
Sure we have not heard of anything being in the T-mobile fw... but also who here can say that they have a FULL BUILD of the Tmo fw to examine? No one.... there is a generic 2217 build floating around that claims to be official, yet it is the ONLY build that does not have an OTA formatted file structure. All the 10 Pro OTA have been in payload.bin format, yet this happens to come only as a decrypted OFP, or a compressed OFP. *** OPPO is not directly supporting the 10 Pro 2217 or 10 T 2419 ! As these are proprietary T-Mobile builds. This is why you cannot find either of those models fw in the Oppo repository. So if OPPO doesnt release builds for TMO, then how exactly did an "Official 'OFP' for 2217" get released? *** OFP is an Official OPPO format for all the OPPO model phones. 10 Pro is still branded Oneplus, thus just about any OFP file you find in the wild, is almost 100% guaranteed NOT to be an official released build for our phones. Every package for this and the 10T that they have OFFICIALLY released, has been in Payload.bin format, because they havent released any full images yet! So in theory, who's to say that TMO didnt place an efuse into their specific model? Its only code, and if set, then it could have been burned during the initial release, or a later update, like AMAZON did with updates to the Firestick/FireTV devices, which would ONLY allow newer updates to certain files in THEIR build. That would totally explain a bootloop, because the rollback packages all push you back to 11_A.013 .... that build is from Feb-March 2022. Rolling back would almost guarantee that some files are overwritten with older components, which would cause a brick by e-fuse standards. We had to be lucky enough to catch it early in the FIrestick forum, to stop ppl from installing the update. Everyone who did, had their ability to unlock/load custom fw to their devices blocked, and there is still today no way to circumvent it. Sure new methods to mod became available, but only minimal changes, cuz the e-fuse blocked downgrading to exploitable builds. Since TMO has gone this far to stop us from modifying this phone, you can bet solidly on the fact that they have several safeguards in place to protect their investment.
Now im not trying to discourage anyone or discredit anything anyone has said or experienced regarding this phone, but look at the NUMEROUS unanswered replies to handfuls of problems that only happen to 1 or 2 ppl... they all have the same final result, but its astounding how many different scenarios ppl have found, that no one else has experienced, yet it leads to another bricked device. If this problem was rampant among a significant number of users, and it was triggered by the exact same scenario, then TMO would have to address it with an update... But all we know for sure is that there is some file(s) that is not compatible with any other model except the 2217. Til we have an EXACT culprit identified, all we can do is speculate, which is why I am going to re-label this as HIGH RISK in the OP. It has about a 40-50% chance of causing a bootloop, and about a 10% chance to leave your device unresponsive! There have been several released guides for other devices that have close to the same success rate / risk factor. All i can do is share what I have done, and what i know from personal exp.
Im sorry if anyone lands themselves on the wrong side of that equation, but it is a risk that only you can decide if its worth taking. For me, that answer is and always will be YES because i will not own a device that i do not OWN! For others this may be a touch more out of their league, and if thats true they should steer clear, until I or another user can get hold of an official TMO OTA, to examine the diff files in each.
****** Now all of that being said.... if ANYONE wishes to contribute to finding a solution to this dumpster fire, I am not asking for donations.... What i am asking, is for SOMEONE who might have a T-Mobile 10Pro on the release build, or any build PRIOR to 11_A.13 and is looking to help, we NEED an exact copy of an OTA update that might be sitting in your notifications. All updates download to the /sdcard/ partition of your phone in a folder that is accessible without root permissions. If you accept the download for the update, and DONT begin the install immediately, you can locate and pull that OTA to your computer, then delete the file from your phone, and it will cancel the update on reboot. No loss to you, but EXTREMELY HELPFUL to us, because we will have something from TMO to work with, which may give us a clue as to what we need to remove from the updater script ! *******
and FYI the signatures used to sign some of the OTA we already have, are already deciphered and as such can be used to create new signatures after making some changes to the respective regions package. But to make having these be of any value, we need to know what to take out or change in the manifest, that will prevent alterations of the files causing bootloops. If anyone can help with an upload of a TMO-OTA please share publicly or dm myself or one of the other devs who have expressed interest in this issue.
Thanks
I can probably pull the update from my wifes phone. She never updates anything. I did get my 10 pro to boot to android 13 but everything just says its disabled. This is only the 3rd phone ive done this with so ill warranty another one if i have to lol.

Yup, this happened to me as well. Setup wizard crashes before I even get very far in it, and I've wiped multiple times trying to complete it somehow.

Ive tried to convert multiple different ways. Upgrading to 13 basically screws you with the disabled apps BS, Downgrading just crashes the device. Either way its broken. I've went through 3 devices now messing around.
So I guess it's time to replace it, then? Crap.

Start a RMA on OnePlus website, don't go through T-Mobile. They will have you send in phone and then either reflash your phone and send it back or just send you a new phone which is what they did when I had to do it. All that bs about voiding warranty when unlocking bootloader is just that, bs. They fix or replace without any issues but you have to go through OnePlus.
FML.
I've gotten it working for the most part, but what's most concerning is that there's no IMEI. And it doesn't charge or even acknowledge the cable. Fantastic.

I can't even request an RMA as I don't have an IMEI to provide. It's blank in the phone. I think I'm screwed. Or try T-Mobile. Dunno. This sucks.

The T-Mobile version has your IMEI sketched into the back cover of your phone. You should be able to use that.

Oh. Uh.... completely forgotten about that.
I just updated to Android 13 on the TMO NE2217, device not unlocked, still financed. And now have the option to unlock the BL.

Is this still useful, with the NE2217_11_C.26 update? And either way, how can I delete it? I couldn't find anything big in /sdcard. Thanks!

THIS Please my phone ignored my saying no and next reboot the damn thing will go off on me ... so frustrating that even when you set the darn thing to OFF on auto update and such it STILL does this BS...
Damn TMobile and their special lock junk UGH ...
anyway ... please can one direct with a screen shot and file manager they used to find this file so I can delete the thing? ... I have tried to find it and struck out ... but having got the notification today and the Oxygen app is showing 'REBOOT' instead of 'resume' when I ignored the update previously has me thinking if I reboot I will see android 13 pop up and in this case means I will lose my whoop as something with it breaks pairing my wearable ... whoop has offered no timetable for a fix
