MSMDownloadTool Custom ROM - OnePlus Nord N10 5G Questions & Answers

Hello,
I was installing different custom ROMS for this phone, then reverted back to Stock ROM. It updated itself, and IMEI got erased somehow.
Is there any way possible to flash a custom ROM, or even custom recovery using MSMDownloadTool? I had a global version N10, so it was sim unlocked and bootloader unlockable, and I do actually have my IMEI on the back of my box, but can't put it into my phone as I have to root it. But I can't root it because the bootloader is now locked, and the bootloader is now locked because there is no IMEI......
This leaves me locked out of fastboot, so the only option is edl, which works just fine. However, only MSMDownloadTool is compatible with this mode, and it only installs Stock ROMs.
I tried extracting the .OPS files, replacing the stock recovery with twrp (and then renaming it to recovery.img), repacking the .ops then installing it. It installs, but then never boots and is just stuck in edl mode until I reflash the normal stock rom with the stock recovery.
What Do I do?
Thanks

If your bootloader was relocked, encryption and partition checking were enabled again.
TWRP would only cause your phone to register as modified and lock itself...and due to streamlining of a lot of functions, you can't even use the dialer to enter the menu needed.
Best you can do is totally wipe everything on your phone and generate a new android ID. (You have to do this from the actual OS instead of recovery though. Recovery format uses predetermined instructions. The format option from the android settings panel has a different set of instructions and one of them is to generate a new android ID, which includes IMEI)

Thanks for the reply, although im kinda confused by your answer. How do I generate a new android ID? (what does that even mean lol). I checked in my settings and I can't find any "format option"

Android ID is what determines your phone is the phone it claims to be when pinging google services.
Move any files you want to keep to somewhere safe. Format your phone, android will push you a new id number. It won't fix your IMEI, but it'll keep your phone from being absolutely useless in the process.

After your phone is formated and has booted back into the OS, you can enable adb. Adb into fastboot, use fastboot to determine if your device is still bootloader unlocked using the fastboot oem device-info command

I tried everything you said, reset everything, still no IMEI, and even if the Android ID is different it hasn't really changed anything. Just to be clear, when I flashed the stock ROM earlier, everything worked as intended apart from the SIM card (which doesnt work at all) and the WiFi (which keeps dropping after 5 seconds of connection). Those problems persist even now.
Guess I'll be messing around with the SMT mode in MSMDownloadTool since I've already lost my IMEI, see what I can do from that. If there's anything I do actually end up finding out, I'll post it on xda.

Update
I installed an update by download a zip, installed update via settings. System rebooted to complete update, and somehow the oem unlock option opened!!
From this point, fixing it will be pretty straight forward I think
Thanks for your help

Nice! If everything is working properly besides the IMEI at this point, there's a couple of PC applications you can use.
I'd recommend write dual imei, not gonna post a link since IMEI fudging is against the rules (even if you're just trying to repair your IMEI)
Use the IMEI that's on your device sticker or on your phone packaging specifically.

Either way, hoping you get your phone back up to 100%.

As it turns out, it's not easy at all. My WiFi has exactly the same issue... keeps dropping, No SIM card, no baseband version. What's crazy is that I have rooted, and even repaired the IMEI via a tool. If I read the IMEI via the tool (and different ones just to be sure), they will all show the IMEI the same as the one that I wrote (which were the original ones).
But for some reason the phone still doesnt recognize it. I reboot it. Same story. The tool recognizes, the phone doesn't. I know for a fact that the issue cannot be hardware, at least for WiFi. If it was, it wouldn't connect to any network, but it does, and then disconnects after a few seconds. I think I have been all over every post on the internet regarding this issue, but still no luck.

Honestly, check with OnePlus if you're under the 1 year warranty window. This sounds like an issue that can really only be fixed with a replacement device.

Hi I have a similar problem.. My phone oneplus 8t is stuck in 'SMT Download failed error' mode. I was tryimg out custom roms which has caused this. My phone says can only be fixed via SMT Download mode. Can you help me out using the SMT download mode? I have tried MSM Tool normally to unbrick my phone but it doesn't work.

hello @nightfury04
If you have a Oneplus 8T you have to download the appropriate MSMDownloadTool (specifically for it) and make sure the version is correct too. Is your phone global/ locked to a carrier?

[SOLVED] [Q] Bricked LG L9 P769, locked BL, JB, Rooted, LG Bootloop

Hey all,
I have a CWM backup of my current rom and have backups of apps and data but am stuck at a bootloop.
As I have read countless articles, it seems my error is because I have a locked bootloader(not actually sure). Though, I only tried to flash
clockcycle's wiped v20d cwm backup file. It failed part way saying it couldn't write to /system.
Since then, I haven't been able to fully enter CWM. just see the red triangle with the droid guy on his back.
I have read Cmahendra's unbricking guide but it doesn't work as I have installed JB and even the tips to unplug, wait 10s and reopen the program to flash again it still won't work. Still stops at 15% saying error connecting to the phone.
There is a similar thread which had this exact problem which said to
use the online method to recover your phone since I had already installed JB. I edited the hosts file to remove the fake offline server and opened up the b2CAppsetup.exe, clicked on customer support,
entered my model LGP769BK and my S/N and it began to start the process and 'analyze' then crashed and said "updating is not possible any longer due to a fatal error while the LG mobile phone software Update"
I've tried to search this out myself and not waste any space but I'm at loss here. If anyone has any help, it would be much appreciated
as I don't have a phone while this is not working.
I've tried all the ways to to hard reset, master reset and still I get the droid guy on his back. I can get to S/w mode like all the other posts say to do but none of those fixes seem to work for me. Am I missing something?
Do I have any options here? I have kind of read that I should just unlock the bootloader but I don't think that applies in my case as I can't turn on my phone fully.
edit: for the online method(LG support tool), it basically cancels when it goes to the 'downloading' phase --> this is what I've seen as most of the answers but doesn't work
Upon further reading,
many seemed to need to replace their u-boot and x-loader
I did so and installed fastboot using Lelus' script here:
http://forum.xda-developers.com/showpost.php?p=41768774&postcount=1
I used option 6 which allowed me to flash the u-boot and x-loader from p760(works with my 769 and others as it says in the options) for JB
I'm not sure if I needed this as I don't have an unlocked bootloader.
I'm not sure of commands in fastboot but I ran
fastboot devices and it showed something
I also ran: fastboot flash recovery recovery.img
and I put one of my cwm backups in the "yours" folder
After I activate fastboot, it brings me to the C:\fastboot\yours folder
I assume this is for me to put my intended files in but I'm unsure if I should use my cwm backup or something else?
After it flashed the recovery img, I sent a fastboot reboot command
but it still went back to the droid lying down with a red triangle.
As some of you may see, I'm not too great with this but I feel like I'm close. Does anybody have an idea of what I should be doing?
should I flash an update.zip?
I don't know many commands but hopefully this gets me going in the right direction.
PLEASE HELP ME!!!!
I guess your cmw restore formatted your system but couldnt load the new system
the recovery you run with a locked bootloader uses a technique called 2nd init which i think is somewhere stored in the system partition. so when the recovery formatted the system, it lost itself too.
I've had a similar problem. the way out would be booting into the SW upgrade mode--switch off the device, remove the battery, remove the usb cable. press the volume up button and connect the phone to the computer. wait for a couple of seconds and then insert the battery.
you should be in the SW upgrade mode
now use the B2C client. if it gives an option to upgrade, use that otherwise, go to the customer support menu and press recovery phone
I have already done earlier. It may have gotten lost in my frenzy of information. I have put the phone into software mode, as you said, and it won't work either; There's no option to click upgrade because it's JB(V20D) and when I click recovery phone and enter my imei, LG mobile support tool(B2capp.exe) analyzes and then has a 'fatal error'
Since I flashed the new u-boot and x-loader my screens are all backwards/mirrored. Maybe the tool flashed an unlocked u-boot and x-loader if that's possible.
Is a recovery possible by fastboot?
I have a clean and full copy of my cwm recovery as well as apps and data backed up, I just need to get this phone in working order

If you fastboot flash the u-boot and x-loader from p769(ICS) it should go thru with the offline flash detailed in cmahendras guide.
http://forum.xda-developers.com/showthread.php?t=2085344
Use the KDZ_FW_UPD.zip from this thread
Or try this
Remove all of the stuff you have downloaded for this. Download the original B2C client from LG's site and use that

I have the updated kdz fw upd .zip from the unbrick and root thread as well as downloaded a new, official B2C client but they all still hang at the download part during phone recovery.
Tablechair, that did the trick.
Is this because the tool we use to flash for the offline method doesn't recognize the x and u-boot loaderse of JB?
After I installed the ICS boot loaders, my software upgrade mode wasn't mirrored anymore.
I did as tablechair and flashed the V20D.
Does anyone understand why this problem happened in the firstplace? Maybe I didn't get a full copy of clockcycle's backup cwm
or should I have not flashed his recovery in the first place since I didn't have an unlocked bootloader?
Again thank you for all your help and if anyone can provide answers to my other supplemental questions, that'd be great.
Off to root and probably unlock bootloader to be sure.
edit: I can't find the thanks button. but thank you very much tablechair. much appreciated. Hope this can help someone else
p.s. also big thanks to those who made the fastboot program for p769(Artas182x and sguerrini97). really an invaluable tool as I now know.

Things don't always go according to plan, maybe his Clockworkmod backup was made from the touch version and he didn't have artas182x second init recovery installed. So when the cwm failed the first time, did you try to restore your cwm backup?

Not yet. having problems flashing a kdz again. I've tried the 2 different software modes, as well as setting emerg and diag but still getting stuck at 15% again.
Do i have to replace my uboot and xloader with the ICS ones every time I want to use the offline flash method?
edit: yup, after replacing with ICS loaders again i'm able to flash using software upgrade. will update on whether I can restore cwm

I realized I misread your question. When I flashed before the incident, it failed to write to system and I didn't restore my other folder. I rebooted and it was all missed up. Anyway, now that I've got everything back and now with an unlocked bootloader, i was able to recover my old image. However, data isn't working so I have to find the radio to flash as I recall reading in other threads.
Can someone explain in laymen terms why this is? recap, i was on unlocked bl rooted jb and I flashed my old cwm backup when I was rooted but had a locked bl. My apps and messages were all there but the radio was different. I'd understand if I was going from ICS to JB but I was on JB both times. The only difference being a locked BL. It's got to be something about the Radio from p760 or V20B that didn't work on my earlier backup or something like that because the layout status bar is different with a "data" button and showing H instead of 4g(which are the same afaik).
Since, I restored to my backup from after my bootloader unlock and root so data is working showing 'H' with the different layout
Also, I had problems backing up and restoring until I noticed that it works better when I power off the phone and do the manual commands to enter recovery as opposed to using the app to send me to recovery(where I incurred /system backup errors).
My last question is which cwm recovery should I use? I currently have the one for a locked bootloader installed as per Artas182x's website. On that post he has a link for an unlocked bootloader recovery on the xda forums but that thread was updated to not working. Are there any disadvantages to me using a locked bootloader cwm recovery?
I don't think I have any option but to try it as I want to flash CM10.1 for p769. I also read that if your bootloader is unlocked, you can download the cwm from the googleplay. If this is true, can I just install over or should I uninstall the Artas182x locked bootloader one????
update: have to remove l9 recovery by deleting the appropriate system folders and then flash the appropriate .img through adb commands
Help.

Although I might be late, I have the same problem and the same phone and I really need help. I have a soft bricked phone lg optimus l9 and I had the same problems that you had exactly... Which is weird exept I don't have Clock Work Mod or anything ... If you get this I would really appreciate some help. Thanks
yup me too
I finally got software upgrade to work with my lg p769 that was security error cuz i still haven't unlocked the bootloader, if i knew what a good job lg and T-Mobile did in locking it i would have waited and got a g3 that my buddy rooted in like 5 min and unlocked the boot....
What worked for me is this LG FLASH TOOL 2014 THREAD ON XDA
http://forum.xda-developers.com/showthread.php?t=2797190
flashed both the 20H and 20D successfully i uninstalled everything lg in the control panel first though.
Hope this works for you cuz i was struggling on and off for a month to get this far lol
the 2014 tool ultimately worked for me too, once I fixed a couple things. I had rooted and forgotten to unlock, so it was at Security Error, and it would also disconnect at 15% .. in the 2014 tool, I had to install all the updates even though I'm in windows 7 or it would keep doing it. All good now.
I have been trying all these methods and I am still not able to get in the S/W upgrade mode. The only thing I am getting from the device is being able to put it fastboot mode (The inverted one). I really want to revive this phone
Thanks in advance for any help given

Hey, it's been ages since I have done any of this but IIRC, if you can get into fastbood mode u can still get into software mode,
- turn phone into fastboot mode
- open the software upgrader thing as you normally do
- maybe switch emerg to diag or something like that
- this part is where it's slightly different than the normal way(same program but u select a different option than the default 1st option on
I think if yoiu look through the tutorials it does mention an alternative method for getting into software mode
in one instance in my past, i had to reflash the ICS boot drivers so the software installer would recognize that
the flashing of the ICS boot drivers is done through fastboot. Should be a post in my history where I asked a question regarding this.
Sorry for the chaos but maybe this will help you get in the right direction since I don't know any of your phone history and what you've done etc
best of luck mate

Hey, I have been trying it with the fastboot but it keeps timing out and not allowing me to finish. One thing I should let you know is that, ever since I had put the device in fastboot, I am not able to get back the S/W upgrade mode. Dont know if that will help in seeing what my problem is or if you want me to explain everything from the beginning again, I am more than happy to.
Have you followed the steps that I linked to in the first 3 posts of this thread?
Follow the steps to flash the ICS bootloaders in fastboot and then you can do the fastboot trick for getting the software to recognize your device.
Right now your phone has the JB boot loader on it and is thus not recognized by the software.
recap:
step 1: flash the ICS bootloaders in fastboot (look at the linked thread in post 2)
step 2: use the software in emerg or diag mode but sitll follow the same steps as the tutorial. I think my earlier posts should explain precisely.
if you dont flash the ICS bootloaders, it won't be recognized by the KDZ installer

Dump contents of entire device (partitions), then convert to KDZ/TOT firmware image?

I have the LG v10 from T-Mobile. I bought the phone a few weeks ago and it had Marshmallow installed. Somehow I managed to install TWRP/SuperSU, but then had issues and flashed the official/stock MM image with LGUP. Afterwards I discovered that MM for this device is not currently rootable, and TWRP cant be flashed via fastboot because MM blocks it. So I returned the device to T-Mo store, lied and said it force-upgrade to MM and had began freezing up. They did an in-store trade for an identical model that had 5.1.1 Lollipop.
The device is currently still in factory condition in every way, with the exceptions that I unlocked the bootloader via fastboot and installed TWRP. Nothing else is modified yet and no custom ROMs have been flashed.
I recently became aware that there is no stock LP image for the T-Mo v10, only MM images are available. After all the issues I've had, I'm now paranoid and want to have a complete dump of the phone's entire contents (partitions, bootloader, system, etc) that is in KDZ or TOT format, and can be reflashed with the standard tools available. Since there is nothing official then I would have to do this myself. This would be useful in the event that I run into lots of issues and need to do a emergency stock restore.
I found a thread by XDA user @tungkick, in which he created a modified dump of the device while it was running LP. However, because it was unofficial and he didn't disclose this upfront, his thread was shut down. His file bricked multiple MM users. I assume it would work if one was still on LP and hadn't upgraded to MM. Not to mention that I cant seem to find his file anywhere. So I figure the safest way is to do this myself. I would be willing to make this file available to the community when finished, with full disclosure that it is unofficial. But the problem is, I don't know how.
I know that the Linux dd command can be used to dump images of various things, and I have read that this can be done on PC by connecting to the device via ADB or fastboot. This would hopefully result in an image file that contained the contents of all the device's partitions.
But another issue would be converting it to KDZ or TOT. And it would have to be done in such a way that it would be flashable with the standard tools.
Can someone please give me a technical understanding of the tools and knowledge I would need to undertake this? Would it be too complicated for someone like myself that has little Android/Linux experience (but is generally competent with computers/technology)?
Thanks for any advice!
Noone can help me with this?
To the mods/admins: I think maybe I posted this in an area where it is unlikely to get any useful answers. Can someone move the thread to the Help& Troubleshooting area of the general LG v10 forum (not here in the T-Mobile subforum)? Thanks!
I think it's just that if that could. have been done someone would have done it already. Even tungkick didn't make one for tmobile for some reason. I think because he made his root injected files from official lg files and lg has not released a kdz or tot for tmobile LP.
Just my observation... I could be wrong.
Sent from my pretty nifty brand new LG V10
@ planetbeen: I don't see why it wouldn't be possible. Linux's dd program can dump almost any connected device that it can see. But then it needs to be converted into a standard TOT/KDZ that can be flashed with any standard software. Which is why I want to create an unofficial backup of the entire phone before modifying it further, so I can do an emergency restore if necessary. I just need the right instructions from people who have the technical expertise.
I had trouble with my old LG v10, I had used LG's LGUP program to flash it to Marshmallow from my PC, only to realize that it couldn't be rooted or have a custom recovery. And I also discovered that I couldn't downgrade to Lollipop. So I returned the phone to the store and exchanged it for an identical model that still had LP. I just told them it had auto-upgraded to MM and started crashing. They exchanged, no questions. Before this I had various issues, like GPS crashing randomly when turning it on, Bluetooth also doing the same thing, and the Settings app also crashed sometimes when accessing the Security menu. I had flashed multiple ROMs, but stock-based and CM/AOSP-based, but kept running into issues, oftentimes the same ones. So I figured that something in the phone had become corrupt and figured that flashing stock MM would fix everything. Big mistake. I'll never let this phone upgrade again until MM is solidly hacked, which from what I've read may be a long time away. I paid enough for this phone and I really value hackability. I'm not the average Joe that just uses my phone for Facebook, etc. To me, if a phone cant be hacked, then buying/owning it is a waste of time/money. Same thing with every computer/electronics device I've ever owned.
Thanks again!
It looks like I'm going to have problems getting answers from knowledgable people, so instead of waiting, I'm going to take a little initiative and at least try to do the dump with dd. I found a post by @tungkick that says to enable USB debugging and make a backup file via dd with the 'adb shell' and 'su' commands. Is the following syntax correct?
dd if=/dev/block/mmcblk0 of=/sdcard/H901.bin bs=1024 count=6291456
Do I run these commands from a PC via command line while connected via USB? Or directly on the device in a terminal emulator? Or do I need to run the command while in fastboot/bootloader mode, while Android is powered down?
Thanks again!
Stock use tool extract kdz then choose file dz (use lgup)
remember can not flash if phone update 6.0
Never downgrade because phone brick now.
version 5.1.1
https://drive.google.com/file/d/0B_Hol5T47S-bQkJVemgzMDV0Nzg/view?usp=sharing
@ tungkick: Thanks for the info. I had used the dd command to dump my phone to external SD before, but the file was 6GB! I was unable to use Tool KDZ Extract to extract the *.dz from the *.kdz file you provided. I was able to flash your KDZ with LGUP, but it boots me into TWRP recovery near the end.
Do you mind if I publicly distribute a mirror copy of your file on my Dropbox, so that it will be available to others that need the stock LP firmware for this device?
Thanks again!
I just wanted to say that flashing your KDZ has possibly screwed up my device permanently. Your image has TWRP, not the stock recovery, and is pre-rooted with SuperSU. Normally this would be good but...............
Near the end of LGUP, the device boots into TWRP. System and MicroSD are mounted, but nothing else (data, cache, dalvik, etc). I was able to obtain a stock recovery *.img, then copied it over to my MicroSD while in recovery. Then I flashed it, booted the phone into stock recovery, and performed a factory reset. Afterwards I booted into system, and all looked good, until it got to the "Checking connection" screen, then a lot of apps started force-closing repeatedly. Because of this I can't get to the Home screen, and no amount of factory reset is working. It just keeps happening over and over again.
How to get out of this mess, anyone?
Help please!!!
Still looking for a solution and would really appreciate any help!
My theory is that the /cache and /data partitions somehow got corrupted during the flash. So I tried booting into FastBoot mode and issueing the commands:
fastboot erase cache
fastboot format cache
fastboot erase userdata
fastboot format userdata
It just says something something along the lines of "remote: cant format/erase in an unlocked state". If I relock the bootloader, it says that it cant erase/format in a locked state.
TWRP still cant read those partitions (they won't mount and cant be mounted), and the apps still start force-closing almost immediately after rebooting into system, before I can complete the setup, preventing me from getting to the home screen.
@ tungkick: Is there any possibility we can arrange a TeamViewer meeting to fix this?
Thanks!

Need help with root for Galaxy SM-J320VPP / android 6.0.1

i know this is a newer phone but i'm still pretty surprised i haven't been able to find anyone that's rooted it yet. i've been all over the internet it seems. this is the :
Samsung Galaxy J3(6)
SM-J320VPP
Android 6.0.1 Marshamllow
Verizon pre-paid plan/network
i see lots of videos and guides for other j320f or j320p (close but no cigar) and nothing works. what i've tried so far:
- Dev mode enabled, USB debugging and OEM unlocked.
- any/all 1 click root apps. none worked, and i'd like to avoid these anyway unless you know it works 100% for my version. at this point i'll try anything.
- recovery / flash superSU. only i haven't even gotten past flashing a recovery. i've tried several different versions of Odin with several different versions of recovery .tar's and for each combination i've tried Odin simply fails. big red FAIL button in upper left corner. sadness. this seems like what i need help with. i have SuperSU downloaded so if i can just get a custom recovery working for my phone i'm hoping it's a simple process from there of booting into the custom recovery and then installing the SuperSU. presto.
is there no hope? is there no tested, confirmed working recovery that i can flash to my phone using Odin? i've tried Odins 3.07, 3.09, and 3.11.1. various custom recovery .tars but the only one i know for sure is the J2 version official from TWRP's website (yes i know it says J2 but someone on another thread said it's similar enough to someone ELSE's model "j320f" or something so i gave it a shot) the other recovery .tars i tried are suspect since they had generic names "recovery.tar" and were downloaded from links provided in many different "guides" that i've googled.
internet, you have failed me. thus do i issue this challenge to all those mighty phone hackers of the land. come forth and slay the evil giant that is my phone's ludicrous security (seriosuly how is this even a thing still in 2016. my phone can do so much more, so much better but for these shenanigans).
thanks so much in advance!
EDIT: not sure about the bootloader. i may be a complete idiot. yes. ok. i'm onto something. gonna post this anyway for any other poor soul that has this version phone, but i think Odin's probably failing because the bootloader is still locked. and Samsung doesn't make this easy like motorola or HTC. T_T. once more into the fray! i'll see if i can't track down a method for unlocking the bootloader on my phone. should i return victorious i'll go ahead and share my steps with the rest of the class.
EDIT2: there is no waking from this nightmare. i dig and dig and dig and can find no root. *sigh*
-- i've got android studio installed. and the java SDK platform-tools which contains the adb.exe, fastboot.exe, etc.
-- something i should explain here: in all these guides whenever there's a step that requires the phone to be connected to the PC, it simply says to, you know...connect your phone. but MY phone by default only uses the cable for battery charging. i have to (on my phone) swipe down from the top, select the "connected for charging" message bringing up "Use USB For" options, then select "Transferring media files" option. THEN my phone shows up both in my windows explorer and displays as a device when i run "adb devices".
--when i run "adb reboot bootloader" this does the same thing as holding down pwr/home/vol down - phone boots up into a blue (teal?) background with a large down arrow in center, below that it says "downloading...do not turn off target". in the upper left are several lines of system font style text:
ODIN MODE
PRODUCT NAME: SM-J320VPP
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Official
FRP LOCK: OFF*
QUALCOMM SECUREBOOT: ENABLE (CSB)
RP SWREV: S1, T1, H1, R1, A1, P1*
SECURE DOWNLOAD: ENABLE
*the R's above may be A's or vice versa...hard to read font. sorry
--but as soon as i've rebooted into this mode, my phone disappears from adb devices' list of devices attached. regardless when i run the "fastboot oem unlock" command from the adb shell on my PC at this point i get the infamous "waiting for any device" message and then, of course, nothing....forever. i've also installed PDAnet but i think it's hitting the same road block where my phone is only using the cable for battery charging and i can't toggle that option from ODIN MODE. there's also a "USB Configuration" choice under development options on the phone that has the same options as "Use USB for" but this doesn't stick when booting into ODIN MODE. sadness. i need to retire my brain thoughts at this point. will post TL;DR. you're a saint of geeks if you've made it through my WoT to here.
EDIT3: just an observation - the only thing (so far) that will detect my phone in ODIN MODE is ODIN itself. is there a way to use ODIN to unlock the bootloader?
TL;DR: i think odin is failing when attempting to flash because of locked bootloader. need help with unlocking bootloader first? phone defaults to use USB cable for charging only so i CAN change that to MTP while phone is on normal and then run "adb reboot bootloader" but then phone vanishes from adb devices list once it reboots (and cable is then only charging). thus, cannot run "adb fastboot oem unlock" cuz it hangs displaying "waiting for any device" -- can i unlock the bootloader on this phone? or did i buy a phone that's IMPOSSIBLE TO ROOT!?!?
I have the same problem! I need to root it to install the Patch to change from CDMA to GSM! Because I tried without root and it tells me "E: Signature verification failed"
Thanks
Still nothing?
This is starting to look hopeless
we need the stock recovery.img to be able to mod it and flash it through odin. the recovery for the verizon version does not match so odin wont allow it. i asked on sammobile and they said verizon only releases ota on the device. so idk what to do. perhaps someone with knowledge on this will help.
so far what ive figured out our situation is:
we need root to get root.
more specifically we need root to pull the recovery and then mod that recovery with twrp and use twrp to gain root. The root methods that worked for the other variant SM-J320P dont appear to work for ours, probably due to having android 6.0.1
till we get root we are stuck. the rest is easyish
News?
There is nowbody that had been rooted his J3 Verizon yet?? We need help with this trouble!
In this forum (http://forum.xda-developers.com/android/help/galaxy-j3-sm-j320vpp-configuring-cdma-t3414049) Sergio said:
" try root with this root is only for Snapdragon 410 MSM8916
http://forum.gsmhosting.com/vbb/f723...t1994-1946985/ "
The J320VPP has a "1.2 GHz, Quad-Core". There is no place that sais it's a "Qualcomm Snapdragon 410 Msm:8916" processor. You think this suggestion could work?

im gonna try and do a reflash with kies and grab that file myself, ill work a bit on it because i love this phone but no basic root is driving me insane. if you can beat me to posting tell me how you got the file, otherwise ill post here once i find out. I'm not a top of the line developer but i can work my way around and try my best since nobody else is offering to help.
wish me luck.
sorry for the double post but got the files via the verizon software assistant no problem. it ended up in C:\Users\YOURNAME\AppData\Roaming\Verizon_AR\SM-J320VPP_J320VPPVRU1APC3_FACTORY for me, and even decrypted and unzipped itself for me, now we just need to mod a custom thingy into those files and we can work towards rooting. so as i sit here and watch my phone finish flashing back to factory i will look into how we can mod the recovery. if someone is capable of doing it faster i can upload the files very quickly as its only 1.4 gb
well turns out verizon locks the flashing with signature verfication. so unless verizon changes or root is found for marshmellow there will be zero possible root for this phone.

verizon blocks flashing of modified recoveries. so unless someone finds a root exploit for marshmallow we will have no luck.
Has the kingroot method worked for root on your device ??

Hi to all, im new here and i am having the exact same problem! You say that there has to be a root specifically for the 6.0.. So i found that in the Chainfire page they have this https://download.chainfire.eu/986/CF-Root/CF-Auto-Root/CF-Auto-Root-j3lteusc-j3lteusc-smj320r4.zip already (i dont know if i can post links, so if i cant, sorry), it is marshmallow but the model is J320R4, so i was wondering if this could be the solution. i'll be waiting here for a response, i seriously love this phone :c

No, this is not the solution. When using a utlity like CF Auto Root, it must be specific to your model / carrier. Trying to install that will do 1 of 2 things.
1) Just fail in Odin
or
2) Soft brick your device
Since VZW doesn't bother to put out the full firmware files to reflash the device, it's not worth attempting without having the backup plan of the original firmware to flash via Odin.
an twrp is already available for j320p u can try to root your device using it

Bootloader locked. Can't flash roms. Stuck on oneplus logo

Something really weird happened while I was installing roms. Someone how my OEM got locked and I flashed and voila stuck on the oneplus logo. I have my fastboot working properly also got twrp installed. The thing is that my bootloader is locked so i cant flash and I cant unlock bootloader because I cant flash and set oem unlock. I know this is ****ed up and also my volume up key is not working so we have to work without that. . Whenevr i turn on the device the powered by android quickly disappears and i am in the fastboot. If I do oem unlock it sends me to the recovery. I am not sure why i can't OEM unlock in fastboot. I don't care about data and stuff. Just want the phone working. The unbrick guide wants me to press the volume up key to get to the qualcomm flashing. Unfortunately i can't do that. Need of dire help please ;_;
I kind of have the same problem as of 2 days (see https://forum.xda-developers.com/android/help/bricked-oneplus-x-unlock-bootloader-t3816387), which is kind of strange, as I haven't read anywhere else about it on the internet.
I'll be following this topic.

I've solved it bud. IF you have a working recovery and bootloader. Flash the stock OS. It'll flash even though the bootloader is locked and then your can oem unlock and do whatever.

Thank you. I've tried it, but the problem is that I'm stuck with the Oneplus recovery, as I've mentioned in my post. From there, I have 2 options to flash:
1) from internal memory. When I click this, nothing happens (no new screen or anything, nothing)
2) from USB (adb sideload). When I try to sideload the ROM using this option, it starts promising, but after a few seconds, it just says 'Installation failed' without any reason why. Just like for all other ROMS.
So... No progress here. I've also tried to flash the stock recovery (even though it should be on my phone already, maybe another version) using fastboot, but my OPX won't take it because the bootloader is still locked.
Last resort: I'll try the Oneplus live chat tomorrow, but I do not expect any useful information from that...

Well guess what, they could solve it.
Or at least partly. It appears that Oneplus has an updated version of the tool used in the mega unbrick guide: MSMDownloadTool V2.1 instead of V2.0. This tool did it's job perfectly, OOS was also installed, in contrast to V2.0 of the tool. I ****ed it up again after that (oops), but found the tool V2.1 online here (https://github.com/finlayacourt/Oneplus-X-Recovery). Some files are missing here like the system.img, but I just copied them from the folder of tool V2.0 found in the mega unbrick guide. It didn't work as perfectly as Oneplus's tool, but at least I was able to install OOS from the Oneplus bootloader, which I wasn't able to before. So knowing that, in the end, the result is the same as for their tool. A working OS again, perfect! So now I can unlock the bootloader again and continue the adventure.
Now, what I've found is that the mainboard I have on my OPX is a newer version (if you search on Google for 'oneplus E1003_15', you'll find some things about it, not much though). I'm 99% positive that this caused all the problems I've encountered. It is why TWRP couldn't see any storage, why the stock Oneplus recovery couldn't see any storage, why the tool V2.0 didn't work and why V2.1 did work. If I wanted a working TWRP, I had to install a modified version of TWRP which is compatible with the newer version, from here: https://www.android-hilfe.de/forum/...-1-oreo-rom-unofficial-onyx-8-1-x.867374.html (yes, once you're relying on German sites, you know you went very deep). After that, I could install LineageOS 14.1 again. I was unable to install the unofficial LineageOS 15.1 however, but knowing where I came from, what I've gone through and how much time I've lost on all of this, I think I'll just stick with LineageOS 14.1 until this baby can retire...
Got to say I only have very positive experiences with Oneplus and it's customer support, and this only adds to it!

WiFi - cant turn it on anymore - software switch returnes to "off" position

Hey guys:
I did unlock bootloader unload/root according to this guide.
First Wifi worked.
Then I did try to figure out OTA issues, could not uninstall Magisk, so temporary flashed stock image back.
From here on out - no matter, if stock, or Magisk_patched image: No chance to turn WiFi on.
In the WiFi-Menu, if I touch "turn on", it will show for one second: Turning Wi-Fi on", and then just return to the WiFi off-setting...
I did do factory reset from recovery - no success, flashed again (stock and patched) - no success.
I can't figure it out! Anybody an idea?
Are you sure that you are using correct boot.img version? It must be the same version as your system - build number and EU/GB variant must match.
Yes. I did, unless I had an older Version on a different slot and somehow did change slots and started messing around there. Could be an explanation.
Got tired of messing with it. Did download the whole stock rom, flashed it and will stay "unrooted" for now. Not worth the hassle to me.
BUT: What a mess that these manufacturers make it so hard to have working and rooted phone.
My guess would be that you flashed incorrect stock boot image.
Also how come that you couldn't uninstall Magisk?
Rooting is pretty straightforward, even if Mi A3 has a slight complication with missing "fastboot boot" command support, but otherwise it's nothing special. Take the correct boot.img, patch it, flash it and you're done.
First take your phone into fastboot mode. write fastboot set_active a .unzip stock rom and you will see flash_all.bat click it and you will succesfully have brand new rom with no issue. Note:If anything bad happens or goes wrong im not responsible. Its all your decision to do it

Yeah, you need to create first backup manually. The guide works perfectly, I tested all methods (otherwise I wouldn't mention them ). What issues did you have?
The system is probably installed in b partition, you need to set partition a as active and reinstall rom via mi flashtool
