Ok, so I have a X210CM, cricket wireless. everything goes well until i flash recovery. it says it flashes in less than 1 second, which may be normal, been a long time since i had a rootable phone, but when i go to reboot recovery it lists the help commands in terminal. Nothing accesses recovery.

So I rebooted phone, touchscreen didn't work... kinda expected that, usb mouse... got phone set up and reenabled debugging, noticed touch worked... adb reboot recovery... phone rebooted to broke droid with "no command" under him. Ok recovery was wiped and not reflashed?

So the phone is working, gives me the warning boot is unlocked at reboots, but no TWRP. Any help is greatly appreciated.

EDIT: the phone is from cricket, came factory 7.1.2, and has gotten no updates yet. Fastboot says flashing unlocked.
[Miscellaneous Android Development] JHell:
I had the same issue, what worked for me (still have no recovery because don't wanna take a chance on brickin it because it's my only phone) is to keep updating til u get to Oreo update. It may lock u out a few times, just keep tryin to unlock til it factory resets then keep udating. It will relock ur bootloader. Once u get to Oreo, try the method again then post results.
[Miscellaneous Android Development] JHell:
Just tried after the Oreo update...... it disabled fastboot
[Miscellaneous Android Development] jonrobertd:
Weird thing is... I have no update showing, it keeps saying latest software installed (no sim installed so that may be it), I have had the phone for 3 months now, it is not used as a line, just a tinker phone.

But i see the oreo update kills fastboot, so not doing it. Also the cricket owned version x210cm is (as is cricket) owned by At&T... not friendly to root at all on anything.

I guess my next move is gonna be either attempting to flash a pre rooted rom via pc, or a shady one click root apk...? I have 2 of these not used so I kinda don't mind possibly bricking one in the name of science.

might you have a twrp for lg tribute empire, any ideas would be great, thanks
[Miscellaneous Android Development] noidodroid:
I have two or three of these x210 models I'm building one out of all three and I will have the other two left for parts if anyone here is interested in possibly trading or would want to get on the proper channels to buy these as I know we cannot openly sell on XDA anymore. If so just let me know.
[Miscellaneous Android Development] jabu:
I assume you are referring to the U.s. Cellular X210ULM, that's the irritant I've been battling. Mine came with 20c. Flashing to 10c gave me fastboot, but i got the skewed screen with no touch reaponse. Turns out the trick to downgrade LM-X210ULM20c is X210ULM11k_00_UCL_US_OP_1029.kdz

Worked perfect first flash. Went into fastboot and unlocked the bootloader, wiped cache. I'm dumping it with LGUP before root, I'll let you know if I hit a snag.

P.S. I had this happen with my Nexus 5x before. From flashing 8.1 straight back to 6.

i have an lmx210ulma that i cant get to fastboot mode on but have root access to. i was wondering if there was any way i could dd a recovery or boot img into place to fix it or unhide fastboot mode by removing the laf.img
[Miscellaneous Android Development] RJamesS:
Please correct me if i'm wrong but as of right now people who have an AT&T Phoenix 4 210APM that came out of the box with Oreo there is no file for us to downgrade to Nougat to unlock bootloader and install TWRP?
[Miscellaneous Android Development] Duhjoker:
Hello there

Can someone please help me figure out a way to unlock my bootloader on my lmx210ulma.its the mtk variant that uses the 6750 board and 6755 chipset. I made a copy of the partitions and i am temp rooted using mtk-su. Im looking to see what my options are on either replacing the bootloader, temporarily removing the laf partition or compiling the bootloader and replacing it that way.

Custom recovery download
[Miscellaneous Android Development] Duhjoker:
Im sorry? What do you mean custom recovery download? There isnt one for this device that i know of. There is one for the ulm but its a qcom and mine is mtk
[Miscellaneous Android Development] derverOR:
is there some way to put TWRP and for example GSI on PHOENIX 4 (X210AMP)? Android 8.1.0
[Miscellaneous Android Development] noidodroid:
Built 4 of these devices from parts and have customized a few of them. Put a Plasti Dip Bass with white over that with a metal flake and then clear coat and swapped in a blue button and blue ring on the back and so forth. All of these models seem to match up quite well when it comes to parts. Same body, board excetera. Now when I get the time I will dig into these and start unlocking bootloader, TW RP, root, custom ROM Etc. And then see how they run! Thanks to OP for bringing some of this to my attention otherwise I would have never noticed I had these devices here in inventory.
[Miscellaneous Android Development] noidodroid:
Came across this by the Yemen teams. Looks like it could be useful for these. It's an application. I can't say much more about it I guess since that would be advertising and I'm not for supporting cracked industry software. This team guys go hard and everything they do especially lately. But if you Google around I guess you could find what I just posted and give it a try out. It may be a free app it may be a paid-up I'm not too certain I haven't talked to anybody on the team that created it in a little while. Any who have fun

Charge the battery in another phone first. Battery iS dead
[Miscellaneous Android Development] lexcin:
use download mode ??
[Miscellaneous Android Development] Duhjoker:
The battery was dead up until he charged it. The thing is i have an aristo 2 a fortune 2 and a k8+ qc and they all show the same signs as his. Battery dead = charger activity. Battery full=nothing at all. I have tested these on linux and windows and they will not even show as a device being registered in deviceanager or by usibg lsusb. More over i have collected all the appropriate files from the firehose/sahara protocols to use qdl or qfil and still nothing. I have tried every program and every app and trick i can find online and nothing has worked but the sdcard trick does produce some kind of life as long as the battery isnt charged.

Unlocked bootloader or not fastboot or download mode do not appear under the trick. The fortune 2 and the aristo 2 are both bl unlocked. The k8+ nada.

Now one thing i did notice if any one has any experience with tty is that the mtk version of these will show up as a modem under ttyACM0 in ubuntu 18.

There is a way to flash using python on the mtk variant but i cant figure it out and the man who knows how wont divulge any information

[Miscellaneous Android Development] Duhjoker:
The twrp will work for the fortune 2 as long as it hasnt updated to oreo. The best thing you can do is go ahead and unlock the bootloader now and root it quickly. When it updates the arb value to 3. You will not be able downgrade it from there or do anythibg with it at all.
[Miscellaneous Android Development] derverOR:
how to install on Phoenix 4? Android 8.1.0 does not go into bootloader, reboot in system and only. someone wrote that on 7.1 it is possible to make, and how on 8.1?
[Miscellaneous Android Development] Duhjoker:
Best guess is to install terminal emulator on your device and type getprop. Look for ro.lge.swversion_arb. If the value is 0, Download the firmware for the stock 7.1.2 version and flash using lgup. Once done unlock the bootloader and install twrp and magisk.

After that if you still want oreo on your device then you can lgup partition download to flash every partition but aboot. That will leave yout bootloadet unlocked and available for flashing so all you have to is flash a twrp for your device and a new patched boot image.
[Miscellaneous Android Development] noidodroid:
I would look for an edl. Actually you know what I have a dump of this phone I think if it is the same model as yours tell me again what model it is and I will look between the four songs that I have and I will make you a the dump of it he will just have to create your a XML and pray to God that you can get it to work with a Qualcomm loader for firmware such as cheap ill which I can never seem to ever get we're probably I have more luck with emmc. Sorry for bothering me messed up missing ovulated weird words above I'm using voice to text right now space creature tell me where your phone is and I'll see what I can do. Laughing my ass off. I just saw what I texted but I need to go now so I don't have the time dated

---------- Post added at 12:04 AM ---------- Previous post was at 12:01 AM ----------

What models is at 1? I am working on a l m - x 221 Zone 4 I believe it is and there is no options on Mac for unlocking the bootloader but you don't necessarily always need these as well I don't believe. I have read some tutorial some really good ones with smart ideas that I've used in combination with my ideas and I'm going to look into running streams against it and some other stuff a boot record that is anything when I'm going to be able to find and what did know Ian commands there is.

---------- Post added at 12:08 AM ---------- Previous post was at 12:04 AM ----------

I think I already replied to this but my model is the Zone For or which I believe is the LM - X210VPP

I am trying to find a way to unlock the boot loader but I'm not getting any response from any fast food commands with this device at all yet. So I don't see how it's possible to unlock this specific C V-1 device
[Miscellaneous Android Development] Duhjoker:
Does the device boot into fastboot mode? I dont think it does.
[Miscellaneous Android Development] noidodroid:
Edit: Run strings on aboot and boot images is what will probably result in some leads as usual

I havent found a way yet either. When I get time and if I do I'm going to look into manually unlocking through anything I can find.
[Miscellaneous Android Development] Duhjoker:
Ok so turn your device off. Then hold the volume down button. Then plug the usb cable from any pc thats turned on and running. The device needs to have input and output from a pc to register but if it can boot into fastboot it will using this method. Otherwise your adb reboot to fastboot comnands were disabled by lge. The only way to enable would be to flash a rom that had them enabled or jtag
[Miscellaneous Android Development] noidodroid:
Actually you're going to need proper SDK platform tools with a fastboot that has all the commands and then also you will need to be on the right from where within bootloader that has the capability to be unlocked otherwise you're going to have to find a way to unlock that is the problem with our model that we were talking about
[Miscellaneous Android Development] Duhjoker:
No you dont. The interface reads io from the pc wether its a pc running linux windows a mac or an android device. no sdk or ndk required. I know the phone you have i bought one and quickly resold it after contacting lg. Like alot of lg phones that have come out the past few years the fastboot commands have been disabled.

In fact on the oreo roms the fastboot flash commands have been compketely disabled. I have up graded a few lg phones to oreo and quickly regretted it. My fortune didbt give me a chance. My k8+ and aristo 2 were able to be downgraded. Google the problem. Have you talked to teknight? He says so up front.

my oppinion is that you should download and extract the source code and grep fastboot. There are some interesting bits about using a jtag to flash firmware using a send action command which believe it or not can be used in terminal emulator
[Miscellaneous Android Development] noidodroid:
Yes the fastboot commands are watered down but not always are they completely removed. You can run strings.exe (google it) on aboot and boot images for devices and search for "oem" and "bootloader" etc and you will sometimes results. Have not spoke with teknight in a while. I will get ahold of him and see what we cant figure out about these x220, x210 variants etc regarding unlocking the bootloader.

Shouldn't need source kernel or rest really IMO unless you are wanting to really break it down. We could run it on the dumped firm or the firm from firmware repositories here on the web or use strings and other tools i have for investigating bootloaders. I have like 4 of these phones x210-x220 and such. Cricket, Metro, Verizon PP, and not sure on the other. So i have plenty to test on for this.

The test points always work for the most part but its mainly the chinese overseas phones that you see using EDL mode with test points the most. That send command can be sent without getting into EDL or using test points .. id just have to research it for a bit sometime. I have rootkits for various LG over the past years using send and I use to run with an LG team some years back on a few different.. We used a similar approach that this send command uses.

Here i will attach some info and files when i get to my other machines. Keep me updated!
[Miscellaneous Android Development] Duhjoker:
What i mean is that fastboot flash partition partition.img has been compketely didabled in the oreo rom.

The kernel source has the commands and arguments for using the send command feature which is the alternate way of flashing partition images. It works similar to laf. You hace to talk to the boot loader using those commands. Ive been studying it for a while but i dont get it.

I have gotten my firtune 2 to send back some data a few months ago but i couldnt decipher it.

Any i think it would be worth a look if you are really looking to root it. Using a magisk flashed boot image you could flash it that way. (
[Miscellaneous Android Development] noidodroid:
Oh okay I see what you are saying now. If you want some help with it and are on Telegram private message me your telegram name and I'll get ahold of you and we can take a look at it sometime

[Miscellaneous Android Development] f10945yt:
I was trying to get root on my LG fortune 2 (aka lm-x210cm) and I did not find a version for the specific model number. Can you please say whether or not I should try another device's root profile for TWRP?
[Miscellaneous Android Development] NonStickAtom785:
Hope I'm not too late. The first thing you should ask yourself is what carrier it has. All of the x210 phones have the same hardware but if you do not have a carrier that enables OEM unlocking then you won't be able to flash TWRP at all. Otherwise it will work. Make a backup using LG-UP to be sure you can revert if something goes wrong.
[Miscellaneous Android Development] jonboyandbailey:
Twrp and xda are awesome. Joining there team has been the best decision I've ever made.

Sorry to kinda necro this thread.

I ordered a phone upgrade from my old P4, but found out my "infotainment" unit in my car only really supports Android 7. 8 Works, but 10 was a total no go for the app support...

I sent that back and picked up a new ATT Pheonix 4 in box with 7.1.2. It doesnt come for a few days but...

I would love to have this unlocked, rooted, twrp. No custom roms needed because I can just debloat. I cant seem to garner whether this is possible from this thread.

Will the TWRP image work on LMX210LMW (LG W10 Alpha)?
[Miscellaneous Android Development] Paperweight Master:
Thanks much for the info. I've ripped several LG Devices And The Lg K20+ Was The Most Similar To This one, but quite a bit simpler. Also, the LG K20+ had custom recoveries up the wahoo, along with several custom ROMs. Anyhooo, thanks!
[Miscellaneous Android Development] Paperweight Master:
P.S. the link for the USB drivers spits back a 404 error code
[Miscellaneous Android Development] NonStickAtom785:
Ah thanks for letting me know. I'll look into it and update the links. Sorry for the hassle.
[Miscellaneous Android Development] NonStickAtom785:
Good question. Are you able to OEM Unlock it from the Developer Settings? You go to Settings > About Phone and then click the Build Number line until it says Developer Settings unlocked. If OEM Unlocking is enabled in that menu then there is a possibility you could unlock the bootloader of that phone. Nobodies tested it yet.

Please excuse my late reply. An old friend of mine had the same phone as you and was able to root it by flashing the non stock firmware onto it. Which means he flashed the LG Aristo 2 firmware on it without causing too many issues. I still don't know whether it's safe to try this but the hardware is exactly the same. Nothing is different about these 2 phone, the LG Aristo 2 and the LG Phoenix 4. I'm sorry if I'm not of much help. I really wish I had the phone myself so I could gamble for you.
[Miscellaneous Android Development] anan265:
Yes. OEM Unlocking option is available in developer mode settings. But I tried flashing it via fastboot and it failed saying that bootloader is locked. Then after some Googling I found that LG W10 Alpha (LMX210LMW - India) doesn't support bootloader unlocking. Which means eventhough I unlock it via settings app, the phone's bootloader can't be unlocked.
[Miscellaneous Android Development] Cinephile 74:
Sorry to ask such a noob question but its been a few years since I installed #SU and a ROM without somehow settling my system. Could you possibly walk an old man through it, please?
[Miscellaneous Android Development] Cinephile 74:
Cricket wireless has that distinction, sir.
[Miscellaneous Android Development] Cinephile 74:
I'm beginning to believe I've taken too much time off from this endeavor... because I can't for the life of me remember the procedure to flash this modded boot.img. I can't put it in my device's internal storage, because, well, I obliterated it. Should I follow the same protocol for flashing the recovery.img? i.e. place it in the ADB/fastboot folder and go from there?
[Miscellaneous Android Development] NonStickAtom785:
Well you have to pull the boot.img. Then patch it with the latest Magisk root zip. Assuming that your device is already bootloader unlocked and able to be flashed all you have to do is:

fastboot flash boot <patched-boot.img>

It's been a while for me on the Aristo 2 because I've switched to developing for the Raspberry Pi 4b. So sorry if that one doesn't work. I don't even remember half of the things I did for the Aristo 2.
[Miscellaneous Android Development] Cinephile 74:
Yes, I tried installing LMX210APM Nougat And Oreo but now, instead of boring to TWRP every time I'm now stuck in a bootloop at the loading screen. Aaaarrrggghhhh!

I've tired Adb, fastboot LG Bridge.... nothing seems to work! Grrrrrr
[Miscellaneous Android Development] NonStickAtom785:
Well that means you have to go into EDL now.
[Miscellaneous Android Development] Cinephile 74:
Actually, my perseverance paid off? I just not got it back in fastboot and I'm looking for a fresh copy of TWRP and a custom Rom if I can find one. Any thoughts?
[Miscellaneous Android Development] NonStickAtom785:
Well you could use Pitch Black Recovery Project that uses the pi kernel. I didn't compile it but it's hosted as a zip on my Android File Host. As far as Roms go, if you use Stock Oreo you can remove most of the bloat yourself with Adb and or root tools, and add your own tweakable apps.

As far as compiling a twrp image or other recovery image, or even a Lineage OS ROM you need the device vendor blobs. I don't believe Tecknight ever added support for Project Treble, but there are some universal tutorials based upon Porting Project treble support for non treble devices. As well you should check out these things:

Substrantum: for theming

Osmosis Scripts (Here on XDA): For pulling device vendor blobs. I believe what used to be hard isn't as hard anymore. You just need to have the right tools. I don't thing the old CV1 vendor blobs branch was ever completely finished but you should still be able to use some of what's there. This is all assuming that you have the motivation and effort to wait for a large lineage repos to sync to your local storage. And also the compile time.

Sorry for the lack of links. I'm on mobile and in a hurry.
