LG ARISTO [LG M210 T mobile]

Hey guys! How ya doing?
Im pretty straightforward so I'll make this fast.(like myself in bed with a 10/10)
I need some help on my LG Aristo (T-Mobile).
The problem is I rooted it via fastboot with twrp and everything went great for the first few days until it started to flash gray and wanted to become an alien.
I wasn't worrying cause im a thug.
So I attempted a re-flash & I erased the recovery then re-flashed it.
Until the blinky gray alien screen started happening again.
For a few days I tried everything and the gray flashing screen wouldn't go away.
So I did the following fastboot commands and it went away.
Fastboot erase cache
Fastboot erase userdata
Fastboot erase system
Fastboot erase recovery
Satisfied that the gray flashing finally went away I reflashed it with the twrp recovery.
Only this time when I booted into twrp to install No-verity and SU all I seen was
Failed to mount :/system
Failed to mount :/userdata
Failed to mount :/recovery
And the phone did a reboot and was acting funny.
I then re-flashed the boot, recovery and the modem imgs that I extracted from the KDZ myself. And it actually booted but stays stuck at the LG Logo.
I couldn't flash the system img as I kept getting a "max target size download of 190840823 bytes" error.
I looked into it and a friend mentioned to forget it and to just flash the KDZ File with a LG flash tool.
I tried this only every flash tool I used did not pick up my device model. (yes I had all correct LG Drivers installed)
Aftering searching online I also tried to replace the fastboot exe with mfastboot. But it did not work as I keep getting the same error but it said target -max-download size of: 250mb and my system.img is about 2GB+..
Also, the mfastboot was made for moto devices (I found a XDA thread that linked it) and not lg. But it didn't work anyway.
I really think everything will be solved once I flash my system img but I keep getting errors about the size limit. (If you know of a way to fix this let me know.)
:good:I've already tried the following so please don't bring them up::good:
*Erasing everything via fastboot ( doesn't do anything)
*Putting phone into DL mode to flash KDZ and TOT file with phone dll via LG flash tools.(2014 and 2016) ( kept getting a (s) failed to load error)
*Re-flashed stock imgs (done it all but system img. I don't know why It keeps giving errors, yes I put it in android sdk platform tools folder)
* Put phone in dl mode and use LGUP/uppercut method. ( Kept getting "No handsets connected" errors". Phone wasn't recognized no matter what drivers I used.)
*Try different ports on pc and latest drivers. ( Yeah, I spent a week searching for all drivers and my pc isnt a virgin anymore as I stuck in the usb in all her holes)
*Relentlessly search XDA and other forums for solutions to no prevail. (This phone is irrelevant and no one cares about it)
:good:What I haven't tried::good:
*Breaking the mother****er and just buying a s5.
Greatly appreciate any help and also can XDA add the LG Aristo to the "my devices"? I had to pick a s8 so I didn't look broke.:silly:
I didn't seen an LG Aristo and There is NO forums for this problem or even for this phone in that matter.

No one has a fix for this?

Dayuuum
Fuuu, that's hardcore.

Where is the dang lg m210 developers section? It's a very popular device and there is a ton of interest in rooting it. I can't seem to find the device thread here on XDA. ..
Sent from my SM-N910T using XDA-Developers Legacy app

Are you trying to root it? I can give you the twrp for the device and such and a rooting method. I rooted mine successfully its just I think I messed it up by stepping on it lmao

I would post a link but I cant. Just google it and look for the getandroidtips website. I rooted it by working with friends on android forums. But that website getandroidtips has a better understanding.

frp lock
i bought this phone from a pawn shop for cheap but i find out im frp locked out.. how can i get passed this?

Use Uppercut with MS210 Firmware Typically, if you can't get LG Bridge to recognize device you should pull the battery out with the cable disconnected, reinstall the batter and then hold the Volume Up button and then plug the USB cable in while it's connected to yuor PC. Welcome to the miserable world of LG

Any solution for frp lg ms210?

Has anyone had any luck unlocking this phone?I would like to switch from T-mobile to Freedompop.

I need a twrp backup .zip file for this phone. I accidentally wiped my system

One Plus 7 Pro 5G UK - Bricked PLIS HELP.

Yep, thats right, another thread about a bricked OPO
I made the mistake of deciding to unlock bootloader, flash TWRP and run a custom rom, after about 10 minutes of being awake.
Long story short, my device is now stuck in bootloop. I have no recovery on the device anymore, not even stock OPO, and obviously no rom.
I belive this is because i ran the fastboot command, 'fastboot flash boot twrp.img' instead of 'fastboot boot twrp.img' either way....
Device will boot into fastboot, and I THINK, it boots into EDL. The device shows in device manager, and in MSM software, but there is no notice on the screen of the device.
I have tried to get back up and running using both methods below to no joy.

MSM
https://forum.xda-developers.com/oneplus-7-pro/how-to/op7pro-collection-unbrick-tools-t3956595
On the back of my device, there is a sticker, which displays my IMEI number, Serial etc etc, and shows the model of my device being GM1920, a model number I see no where in this forum. So now I'm thinking, "Do I have a device thats not compatable with all this, all i see is GM21AA, GM21AB etc etc.
Some body please give me something to go off, I've had android devices for 10+ years and have never managed to brick a phone into non exsistance. I can provide as much detail as you would like, anything that would help you to help me.

Heya, Ive checked em.
I've managed to fix the issue now, as you probably know, I was being a derp, and just not getting the right varient of fastboot rom for my device, I just didnt have my head screwed on properly lol. Anyway, the device works, I have stock rom, recovery, phone boots into EDL and displays the message as it should, everythings working right. Just need to get TWRP flashed and get a custom rom running now.
Appreciate your reply!! Can I still join in telegram? Would be nice to be in a community with GM1925/GM1920 users.

I have sorted it now bud but still can't flash ROMs first phone I haven't managed it on in years ha.

NV Backup Warning - Dynamic partition invalid. Quite the riddle.

UPDATE: So hopefully this title and OP update take as I don't want to spam the forum with threads. Despite have dozens of Android phones since the original G1 I am stumped by this, but I imagine a guru could solve this puzzle. Here we go:
I messed up my phone partition table when I messed up the last step from the dual boot TWRP thread. I tried fixing my newly bricked phone using MSM tools but it's a converted GM1915 Tmobile OP7P running global firmware. The Tmobile stock MSM recovery pack MEGA link has gone dead, so I tried the Tmo to Int'l conversion files again. The phone booted, but I kept getting "NV Backup warning - dynamiic partition is invalid". I could make calls, but had no orientation sensor, no mobile data, baseband shows blank in fastboot mode, etc. I've tried flashing fastboot ROMs as well but no matter what, the dynamic partition invalid message pops up.
It seems ike this is an EFS issue, so late last night I tried a few more things. IIRC, I was able to flash that persist.img via "fastboot flash persist persist.img", and in any case most everything seems to work now, including the sensors. But, I'm still getting that dynamic partition invalid error and no baseband shows on my bootloader screen. I
'm guessing there's still some corruption in EFS? I'd understood from reading that even with persist.img one good thing was to erase the modem files and persist first, because then they will regenerate, according to this post.
So, I tried these commands with plans to then flash persist.img again....
fastboot erase modemst1
fastboot erase modemst2
fastboot erase persist
It won't let me erase them though, as it says the critical partitions are locked. Do you think this path might fix whatever issue is triggering this message, and if so, does anyone know how to do it? I think I may have use dd, but I'm not sure which partitions I'll be looking to erase and how to do it that way, either.

Maybe try this: https://forum.xda-developers.com/oneplus-7-pro/how-to/rom-stock-fastboot-roms-oneplus-7-pro-t3931424

Thanks, but that's what I've been trying. No joy so far. I need to check because actually it may have hung on params or some other issue that an L2 driver update could fix. Of course me figuring out how to fix that will be the next feat, LOL.

Updated thread title and OP with new info. Phone almost back to 100%, but still getting an error message.

So another update as I learn. Now that I've gotten TWRP and Magisk back on it, I realized there is another odd thing with the phone now. Just before the bootloader unlocked warning screen, for a fraction of a second there's a message that says SMT Download Failed. More reading seems to suggest that using an SMT recovery in conjunction with MSM tool can fix the SMT Download Failed message. Most of these say you need to have an EFS backup, which some suggest that you can wipe EFS (as indicated in OP) and it will regenerate.
I've taken a TWRP backup of EFS, but I'm not sure whether I should proceed with the wipe processes with so many saying you should have an EFS backup (lesson learned, yes you should - and don't delete/misplace it like I did). Anyway, I'm wondering if going through that process might resolve that, as it could be a flag that didn't get set right, or whether or not there's some issue with my EFS that means my backup from the current state is worthless.
Maybe my EFS isn't corrupt after all, maybe it was the persist.img that needed to fix the sensores and now I'm good except for some flag that's triggering the SMT Download Failed message and the subesquent dynamic partition invalid message?

Maybe you could do that on twrp by terminal commands, some fastboot command dont work on Bootloader but in twrp work

That's actually an idea I was kicking around for my next move. I was hoping that before I do that, though, I could get a sense from one of the gurus as to whether I'll be able to recover my IMEI and such afterwards.

The phone shows IMEI right now, and calls and mobile data work, so except for the weird " SMT download failed!!! please check your download flow is right" message at boot start and the NV Backup UI warning Dynamic partiton invalid messages the phone otherwise seems just fine. I'm pretty comfortable with system, boot, and data partition stuff from all my time at this, but I'm just being extra cautious that by erasing my modems via some sort of commands or SMT flash that I can at least get it back to where it is now even if I can't get back to an error-free state.

Have you tried flashing QCN file?

I had heard about and used QPST before, but QCN is new to me. I did a quick search and it sounds like on some phones like ASUS ROG, you REALLY need to have one to recover from erasing your modems. Oneplus phones recreate those if they are erased, don't they?

Create a QCN backup from QPST of your phone and flash it again, maybe that will fix your problem.

Hey man I know I posted the other one up with the issue too but thanks for this after seeing you flashing the persist fixed your sensors I tried and walla they are good now! I still have the same SMT failed and NV Backup warning but at least the phone can auto rotate.

I went and installed QPST again and I can get it to see the phone in EDL mode, but I don't believe I have the drivers to get it into diagostnic mode. If I try it shows GM1915 with unknown USB drivers, but I've downloaded some and they don't seem to be able to get the device recognized properly. Until I figure that out, I can't pull QCN, I don't think.

I did go ahead and try a SMT flash. Unfortunately, while I've gotten it to start, it ultimately gets to "Param preload" then I see the Status of Connection change to N/A and then it just hangs....grrrr...

So if we're both choosing WWAN-DHCP for the driver mode, I'm not sure why it wouldn't work. Right now everything is working and I told the NV Backup UI notification to Never Show so it will probably be a few days before I get around to trying to get the whole thing to flash properly. My OCD is really the only thing that would drive me to do it

Question Is unbricking possible?

Good morning all, I tried relocking my bootloader using the command "fastboot oem asus-csc lk" and at first, it seemed to be a success. However I restarted my device and was met with this error message. "Your device is corrupt. It can't be trusted and will not boot." I've tried searching high and low and it seems that I'm royally screwed, just wanted to confirm that I was though. Thanks for reading my post and any input is appreciated.

If your boot.img is not stock before locking you will get this error. Try flashing stock boot.img. I had a similar experience with realme phone but not encountered this issue with ROG 5
Edit: Sorry since you locked the bootloader i think you cant flash it unless you unlock it again. Give a try with EDL firmware

This is becoming a pretty common issue. I think it's time we make a WARNING thread.

That's likely because the bootloader is locked. It was possible that EDL mode could still allow a full restore, but also quite possible it wasn't going to work because of that.

You may still want to contact Asus and tell them you don't know what happened. They may be able to restore it. I wouldn't tell them you unlocked the bootloader, since it's locked if they ask.

As long as bootloader mode works, You can flash a RAW file to boot the phone back.
Ensure the phone has enough battery power left for a 20 min+ flash,
USB Cable to be connected on the side port, (not bottom charging port - fastboot doesn't work there)
and to use the exact raw firmware file which matches the device model and variant.

Hopefully this time is different, but every report so far has been that it fails. I believe we still need the firehose to use any programs that override the bootloader security on fastboot.

Can confirm it one hundred percent works. Mine was the American variant purchased directly from Asus' website. I don't think that had anything to do with it but my phone is up and running with a locked bootloader now. I really appreciate the help fellas

Glad to hear it. Apparently, the issue was people not following instructions...

OnePlus 8 TMO Missing IMEI and can't unlock bootloader

Hey yall, I really need some help.
So some back story:
I started using a oneplus 8 TMO version and wanted to unlock the bootloader to get android 12 and root the phone. So I went through the process of getting an unlock token and when I finally got it, unlocked my bootloader, flashed the global version of oxygen os, and got it updated to android 12. Everything was working great. So then I wanted to root the phone so I downloaded twrp, booted into fastboot, and tried flashing it. The phone then booted into the system even though I told it to boot into recovery. After about a minute or so it froze and rebooted into a kernal panic. I unfortunately do not have what it said and cant repeat the process, but it booted into recovery and I clicked reason for boot and it said something about the kernal. So after a reboot it then went into crash dump mode. So I had to use the msm download tool (unfortunately I only had the tmo msm version and thought I could just repeat the process because I had slow internet and didnt want to download the global msm tool) to get the phone working again. So booted into edl mode, reflashed the phone, and it booted up. The problem now is that I do not have an IMEI number. I have a wifi address, bt address, and everything else that makes me assume that the efs partition is still ok (but I dont know enough to debate that) but it does not recognize my sim card. The phone also freezed and restarts approximately every 30 seconds.
And now my problem and what I have tried:
Because I have no IMEI I cannot enable oem unlocking in developer settings, cant flash anything in the bootloader - including the unlock token - and can barely do anything in the system because it only stays on for small amounts of time. I have tried many imei write tools such as qualcomm smartphone write imei, readnwrite tool, fastboot imei writer, miracle box, and I think some others but none of them recognize my phone. Ive also tried the oneplus debloat and oem unlock script to try and bypass the setting but it didnt do anything. I have dialed *#801# and was able to enable engineering mode and diag toggle but it still didnt do anything for me. So I really dont know what to do any more. When in the bootloader or recovery the phone does not reboot, so I can stay there as long as I need. Any help on this would be greatly, greatly, greatly appreciated.

Have you tried using the MSMTool again?

Yeah unfortunately that hasn't worked... I've done it miltiple times with the T-Mobile one and can't use any other one because I don't have an unlocked bootloader... If I had a way to bypass the oem unlocking option in the settings then I might have a chance to fix it but don't know how to do that...

try using this version of msmtool(i use MsmDownloadTool V4.0_Win7 on windows 10). it's a bit newer version(5.2.89) i extracted from OP9Pro file. replace the version from whichever unbrick file you download. worked for me. but don't upgrade to android 12 again, the same issue will happen

Thanks for the response! And I am so sorry but what do you mean by unbrick file? I just had to download the tmobile version of the msm tool. I mean to be fair it was uploaded by someone so they probably pre programmed it but I unfortunately dont have the knowledge for that. I am also using msmdownloadtool v4.0. Do you happen to have the links to what you are referring to?
Heres the link to the one that I have downloaded: https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4093043/
Thanks!
EDIT: so once you said that I actually went to the link and there were various versions. So I tried another one and it didn't work but then tried one more and my IMEI was back! I have no idea why that happened but thanks for the idea! I was so happy.

yeah, that's it. it's related to version of msmdownloadtool. some of them must have a newer version. i had the idea from someone else on this forum too. glad it helps. be careful not upgrade to android 12 for now. i think it's because of the way oos12 detects phone varient causing the modem to go crazy. not sure tho. would love to see someone figures it out

Yeah, OOS 12 messed up my phone for a bit until I was able to get OOS 11 back on both slots.
