Factory reset - Problem. - LG Optimus 4X HD

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.

Nexus 6 locked T-Mobile demo

I recently had to replace the motherboard on my Nexus 6. I could only find refurbished ones, and bought one on AliExpress, with item description clearly specifying as unlock. I installed it, and it appears it is actually locked status 2. Looks like demo version used in T-Mobile retail network. Some settings inaccessible u such as developer mode or Apps. Trying to get refund but both AliExpress and the vendor are in denial mode.
I have 7.0, NBD92G installed. Very hard to unlock as I cannot access developer mode to allow usb debug. Pressing build nr several times won't help. I get message "you're already a developer" but actually usb debug does not work.
Anybody can help?
Go download factory image from Google and flash it manually by using the command prompt.
@ShernDog: He can't as his bootloader is locked. He can however download an OTA and sideload it.

Thanks. You are right, bootloader is locked too. Would there be any instructions somewhere on your proposed solution (sorry I am rather inexperienced user).

I think I figured out how to do this but the other question is whether I won't be stuck afterwards being requested to enter the only registered user's login which I do not have (I cannot register a second user, as this setting screen is locked too). Do I need to sideload the OTA corresponding to current version / build or can I sideload an older one?
Download the oldest OTA available, as long as it is a full system OTA (easily detectable by size). You're going to have to bypass Factory Reset Protection to be able to resolve this, and the older the OTA, the better.
If this doesn't work, you're going to have to fight with the place you got the motherboard from, and file a chargeback with your credit card company if need be.
Ultimately I can go for the refund, but there is no place where I can find 64 GB MBs outside China, which means I'll have to wait again for something like 3 weeks with poor backup device, and with no certainty I don't receive again a locked MB.
I tried with 6.0 OTAs (page with instructions I followed: https://developers.google.com/android/ota#shamu) and even with just older versions of 7.0, I got every time abortion after about 45% installation, with the msg that I cannot update with older versions.
I am a bit confused now, I just tried to install same build as what I had installed (https://dl.google.com/dl/android/aosp/shamu-ota-nbd92g-2b65257b.zip), it worked but it looks like absolutely nothing has changed on my phone. I thought it would have erased pretty much everything. Am I missing something?
OTA updates don't wipe system. That's why nothing changed.
Ultimately, I think you're going to have to go for the refund and take the risk that the next motherboard you get is going to be locked. Unless the version of Android you're on can have its FRP bypassed - and I don't think it can - you're stuck.
Thanks, bad news. Would it be worth trying wipe data / factory reset accessible from the recovery mode + power/volume up menu ?
You can try it, but it won't help. Doing a factory reset will cause Factory Reset Protection to kick in, meaning you'd need to know the original owner's account information.
Surprisingly it worked. I could log in with the google account I used before the reset. Everything works, but indeed I was expecting some more difficulties
@FYBRU: This is one of those times where I'm pleased to be wrong. LOL.
Glad you got it resolved.

Phone bricked, won't turn on. Help please!

Hi. So I decided it was time to move to EMUI 9 and after looking at various posts on here I believe the easiest way was to you EMUI Flasher to flash the ROM (coming from 8.1 rooted).
The phone restarted and went to EMUI installer but after 10% or so I got an error. It asked if I wanted to go to erecovery or reboot the device (I think). As far as I was concerned it was only checked that the ROM was OK and hadn't installed anything so I selected reboot. Now the phone won't come on. I've tried holding the power button for an inordinate period of time but it's not happening.
Is there anything I can do?
EDIT - I've tried a different USB port on my PC and can see something in the device manager now ---- Kedacom USB Device > Android Bootloader Interface ---- which gives me a sliver of hope this can be fixed.
EDIT2 - I could send img files through fastboot all day (phone was recognised even though it wouldn't turn on) but couldn't fix this. Gave DC Phoenix a try but no luck there either. Think I've killed it.
EDIT3 - Just in case anyone ever comes across this. I tried below but nothing would work so I contacted someone on Telegram who said the only option was to open the phone up and short it out. No way I was attempting that so I eventually contacted Huawei UK and told them it had died during an update, never let on that it was MY fault! Anyway, they sent out a prepaid envelope to send to a their repair partner. I won't name them here but they have terrible reviews on Yelp so I was a bit apprehensive. I know the phone arrived with them last Friday as I checked the post tracking but I never heard anything from them. Today out of the blue my phone has come back to me in full working order, repaired under warranty! Considering there was only one thing I was really using root for and it was only a slight convenience, I think I'll just leave it as is.
Are you able to flash anything in fastboot?
Are you able to boot to recovery via fastboot? Disconnect the cable after you give the reboot recovery command in fastboot.
You may be able to flash each component of emui, system, vendor, oeminfo, kernel etc. Seems that it's missing most or all of it.
Bootloader sounds like it's intact.
Btw. The easiest way to update to emui would be to wait for an OTA from Huawei.
Personally I don't see a point, pie is not as efficient as Oreo nor does it have any features to merit an upgrade, in fact you would lose features (4k zooming, functional TWRP)

update ASUS TF701T (k00c) android to latest version

Hi All.
I trust you well. I was wondering if I could request your assistance with updating my TF701T to a new version of android. I have tried many methods and none has worked. I am actually more confused now as to where to start and what to download and install. :silly:
If possible maybe direct me where I could get a step by step guide with the links to the correct downloads/procedure.
I imported the pad from USA to South Africa and barely used it.
Kind Regards
Rob
(h-tee-tee-pee-s) androidbiits.com/root-asus-transformer-pad-tf701t-easily/
probably use the versions of magisk + twrp that are linked at the site, as they are tested with that hardware -- the latest versions may not work. i do not own that particular device and am not a programmer -- just trying to help you out. search the web for info if anything is confusing in the instructions -- i can't really walk you through it, but the person at that site may be able to help you out if you get stuck.
you'll need to connect the asus pad to a computer, so you'll need the usb data cable & adb installed on the computer.
you will likely also need open gapps to get the play store + apps working. select processor type, android version, then variant. you can find it here ==> (h-tee-tee-pee-s) opengapps.org <== but i'm not sure how long that will be functional, as hosting is apparently migrating to sourceforge.
please note that there are no w's in either address mentioned previously.
here's an explanation of gapps ==> (h-tee-tee-pee-s + w's) androidfreeapks.com/apk/download-gapps-for-android/
...and there are also download links for various variations at that last address too. cheers!
you will not be able to install *the latest* version of android (it's just plain not out there as a mod for a device this old) but you *can* get something a bit newer than the stock version on it.
best of luck!
one last thing (pertaining to the very first thing you have to do) is unlock the bootloader.
(h...s + w's) asus.com/us/Tablets/The_New_ASUS_Transformer_PadTF701T/HelpDesk_Download/
you will find the utility to do so at the above site. select Android, then under "Utilities"
click "See All Downloads" - therein, the 2nd thing from the bottom in that section is the unlock tool,
which says: Unlock Device App. V1.o (there's only one thing with that name. size is 448.82 kb)
and it will only work from the stock Android version, which i assume is still functional on your device.
Magisk is apparently a newer replacement for SuperSU, which doesn't flag the system as altered...
therefore you *may not* need to install Gapps if using Magisk - that seems logical to me, but i am not certain.
thanks for the assistance Dorkus.........this is killing me....but I will keep the faith and try again
I am trying myself and cannot get the unlock tool to work, performed wipe data reset without google account and still "network error occurred" . Android version 4.4.2

Same here. I tried to contact Asus but no hope... We're completely blocked unless they do something? No other way to unlock?
greetings all, it is i, dorkus, of the house of mallorcus. haha. my name is actually reni.
xda keeps locking me out for some reason. i've now created 2 accounts (3 including the one from which this comment is posted) one even with a dedicated e-mail address just for this, but if i try to log in with either one, i get some "invalid" whatever message. admins: what have i said that was grossly incorrect? those links may not be presented in absolutely the most coherent way, but they're the best reasonable explanations of the procedure involved that i could find with about an hour or 2 of research, which i did because of intending to get one of these devices myself (which has now occurred! yay). besides that, who else with greater experience has chimed in on this thread? yes, i've reset my password, on both accounts. after i do so, both times: same "invalid" message. it's wasted over an hour of my time, when i'm just trying to help these people. it's highly annoying & if it continues, well, they'll just have to go it on their own.
to the point:
as luck would have it,
i was able to acquire one of these devices, still in superb condition, for a great deal from ebay. i have been in contact with Asus support & the word is: it's an EOL product, so the unlock servers have been shut down & there is currently no recourse end users have for unlocking their devices. i feel it's doubtful that they'll fire up a server again, but maybe we can pester them enough to develop a fastboot unlock tool? it sure would have been nice if it worked like that in the first place, but oh well, like the song says:
you can't always get what you want.
i will surely let you all know if am able to make any progress on unlocking my TF701T.
footnote: i also have a TF700 model which is in fact unlocked, has TWRP installed, and is running Android 5.1.1 {zombie-pop} which works a bit better than the Cyanogen mod flavor that it came to me with: somewhat improved user experience, maybe a little snappier too, but speed improvement is fairly minimal. most importantly, almost all of my apps work on it - a few don't even have an installer for Android 4 at the Play Store. the 701 is noticeably more responsive than the 700 model, even running 4.2.2 - the main issue with it for me is not being able to run all of my apps, some of which are purchased. i'd probably sell the 700 if i could get everything on the 701. oh well. it's an excellent reader + portable video viewing device even at stock. it's definitely worth what i paid in the condition received, but it'd be even better if i could unlock the bootloader & get a newer version of Android on it! i could possibly even be so happy that i'd float a couple bux Tim Duru's way, the guy primarily responsible for porting Android 6+7 (the latter of which apparently does not have a working camera) to this device.
footnote #2: the first day i got the 701, i tried to do a firmware update (proper region, latest available. full battery charge. the battery in the one i picked up is in fantastic condition, the thing is practically brand new + functions nicely... but now Asus won't let me unlock it, even though it's well out of warranty! grrrrr) which crashed mid-way & then it proceeded to get into an update / crash boot loop. i was pretty sad for a while, but did not give up & found a way to restore the original firmware (which turned out to be a very minor upgrade) from the SD card, thanks to information in a post here in the xda forums. that post is the link which follows. my thing would still go into fastboot (albeit slightly corrupted) + recovery mode, which enabled an SD card firmware flash to happen {...and lo, my little slab of Jelly Bean was resurrected...} so i did not require the NvFlash tool at all... but it's still there at the provided links in that thread.
to summarize the procedure:
1) format an SD card to fat32
2) download the appropriate firmware from Asus [**please note the region: if you flash the firmware from a wrong region onto your device, you will -hard- brick it + will then be required to use the NvFlash tool**]
3) un-zip the firmware (not completely, just remove nesting - so you have only one zip file)
4) rename the one remaining zip file: t4_sdupdate.zip
5) put that file on the root directory of SD card, then into the tablet (while turned off)
6) invoke recovery mode (power + vol down) & choose the recover [RCK] box (hit volume up, while it's the selected of the 3 choices) and from there the firmware update happens automatically. you can apparently upgrade to any official firmware by this method, but **cannot** downgrade... so i'd suggest leaving it at 4.2.2 until we are 100% sure that there are zero bootloader unlock options, because apparently the unlock tool, from what i understand, only works from the original 4.2.2
without further ado:
https://forum.xda-developers.com/transformer-tf701/tf701t-nvflash-unbrick-solutiontested-t3742848
it's now a few hours later from my original post, near bedtime for me, and the xda gods let me log into this account to make this edit... and it's even allowing URLs now! will wonders never cease? not sure what the problem was earlier, but it was quite annoying. anyway, if it lets me log into the account with the dedicated xda e-mail address, that's the one i'll use in future. username is renigade.

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!
deleted

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
