Ok the web just glitched on me so this is the second time of me writing this novel and patience has grown very thin. First i would never be asking for this help if i didnt already do my 5 days of research and exhaust all solutions i can see. And since this is my second time writing this im sorry but im going to give the short version. I did the fatal mistake of lg style reset while i was rooted i know its a rookie mistake i thought i was completely unrooted and didnt double check it before i continued. i cant boot into recovery at all or if i can its just a black screen. when i boot normally it goes to the lg logo then to a black screen. i can access emergency mode however i cant get my pc ( running xp sp3 ) to recognize the device. I can get it to be recognized when i boot it normally to the black screen and even gain acces to root through adb, When in emergency i get nothing though and i have attempted recovery and flashing through adb, kdz, romtools, lgmdp and a few more randoms i could find in the forums ( i have done a lot of research ) when i do establish root though i cant seem to push or pull files, flash, mount or anything besides adb shell, the rest is filled with error: 0's and sbin/sh "whatever" not found, etc. since i can establish root it leads me to believe this can be fixed. THANK YOU in advance for any help you can throw my way and I'm sorry if this post is vague, poorly written ( like i said second time going through this ) or gets under your skin i know better that you veterans hate reading these posts and im only asking for help because now i am at my wits end. Thank you again
hey it would be nice if you could tell something about lg style reset and that rooted thing..... I don't have any info. about bricking the device like this.... ;-)
just wanted to know as a word of caution....

I m not aware if lg p500/optimus one clockwork mod recovery will work on optimus v.
If recoveries of both phones are same you can follow http://forum.xda-developers.com/showthread.php?t=1318750 to install custom recovery of lg p500/optimus one from emergency mode.

Rooting is the process of essentially gaining Administrator rights to your phone ( So you can access files and gain privilages you wouldn't normally have ) Think of it like a computer and your signed in as a guest when you root your signed in as the Admin, Hope that helps. LG style reset is the factory reset of the phone from the recovery menu to restore the phone to its original state, Which is a huge no no while rooted or a custom recovery is installed.

I attempted that and its a no go. The main problem being i can not get my phone to be recognized by the computer while it is emergency mode and i can not even select an image or anything. I booted it normally ( into the black screen i get after LG logo ) And i dont recieve a pop up with image and i recieve a error everytime i attempt to backup my nv its doesnt seem to be found, Nothing, but the device does get recognized at least.

Are you able to connect to phone from lgmdp when booted normally ( into the black screen you get after LG logo ).
If yes then
dont back up nv
no need the pop up window, press on "select image" in lgmdp and browse to recovery extracted folder for "image folder"
then press "start or download"
fix-black-screen-custom-recovery-custom-roms
I'd've posted it here on xda, too, but it's quite enough manainance dealing with it in one forum already.
the problem is that lg started shipping the optimus v with cheaper hitachi screens instead of the novatek screen it was released with. so the older custom recoveries and roms use a kernel that isn't configured to use the hitachi screen and you only get to see the backlight with no display.

the p500 kernel is incompatible (different chipset.) so the recovery won't work even it the mtd map is the same.
bummer, as that's be a nice easy fix.
Mak Thank you for the progress i have made so far i did manage to get the phone connected through lgmpd as i have before however this was the first time when connected it went straight to emergency ready ( in the lgmpd screen ) I am going ahead to assume that is good i was never able to get it that far. The problem i face now when i press the "select image" button nothing happens, as long as the button is pushed down the word ready in the bottom left disappears and when released the word reappears, However i dont recieve the option to browse any menu for the image. Is there a specific folder i should have extracted to? I'll continue my research too if i find out the problem i wil post it immediately, Thank you again for your help i'm not there yet but definately making progress.
Squid, I knew about that topic too i remember reading it during my research, It must of slipped my mind before i even though about posting this. I'm Sorry ill be more careful about making these posts in the future
Also Squid since the chipsets are different i assume thats a no go, Would it still hurt to try? i'm running on hopes and dreams at the moment. Also when booted normally to my black screen i can obtain root access via adb leading me to believe if i can do that a fix is present somewhere

yes, a no-go. when I flashed a p500 kernel to my v for experimental purposes, it wouldn't boot right for a day even after putting a working kernel back on it. it had to sit with the battery pulled for a few minutes between boots or it would just freeze on the lg logo.
if you follow the adb instructions to install a compatible recovery (currently, BobZhome IHO recovery is advised) in the thread I linked to, you should be fine.

yes, as long as pressing the "select image" button ready in the bottom left disappears. But when you release button you should get a window poped up to select image folder.
Try again to connect in emergency mode and see.

I did follow those instructions previously ( 2 days ago i believe ) When i attempted that i was not able to push the needed files to my sd card unfortunately and i did try multiple times using Xionia recovery. I understand user error so I'll try again with a fresh mind just to be certain and get back to all of you.

I know what rooting is....infact I myself is on CM 6.5.8
what I didn't knew was that factory reset with custom recovery can brick our device..
but I feel this is not true as many people had done factory reset when they had problems after restoring nandroid backup....
I know a corrupted /system partition will cause the 'system/bin/sh not found' with adb if you're booting into the rom, I hadn't seen that booting into recovery.
if you have an older optimus v (2.2.1 froyo original, pv5 baseband) you can
Code:
adb reboot bootloader
to get to the bootloader and use fastboot to flash the recovery or even the whole system.
2.2.2 optimus v with pv7 firmware has the bootloader locked, so trying to reboot into the bootloader just tries to boot to the normal ROM.
My apologies Fundoozzz i was not insulting your intelligence just covering all basis, And from what i understand when you choose lg style reset from recovery it is the same as perform the factory reset from the settings menu which i guess your not suppose to. I by no means am not an expert on any of this obviously, I'm just simply relaying the information i have read on these and android forums as well as my personal experience.
Squid, I purchased this in the beginning of sept. and as i understand the revamped the Optimus in August?? So yes im running the later version and to double back on the posts I tried to push files again and attempted fastboot before still with the sbin/sh not found error....I am still hopeful that this is not a paper wieght however it very well could be thank you both again
have you tried booting into the blacked recovery before using adb?
(hold home+vol down while pressing power until lg logo goes black)
it sounds like your rom was corrupted (so adb is fairly useless there,) and recovery might be working but you just can't see it if you do have a newer OV.
to force reboot to recovery without the button-smashing,
adb reboot recovery
while you're booted normally.
then try adb again.
please cut/paste the errors you're getting with the commands you're using, here in this thread..
Well all be cheese and crackers, Thank you Squid it did the trick to actually push the image to my sd card here are the commands that I used....

Now before i move further just to humor me all i need to do is push the flash_image and reboot to recovery and i should be good from there to flash a new rom. I ask only so i dont mess this up any worse than i have
if you're in the recovery, flash_image is already in the PATH.
Code:

exit
adb reboot recovery
then you should be ready to see your recovery.

install the rom.zip as usual.
THANK YOU VERY MUCH, How I wasn't able to obtain this I'm not too sure lack of knowledge or user errors possibly regardless I am now in CWM recovery and will format and flash my new rom. Any suggestions by the way? I was considering CM7 but i heard mixed reviews about it on the Optimus v. Oh well I'll do some research Thank you again Squid if i can repay this debt let me know, Lets face the facts in reality you just saved me over a hundred dollars and countless more headaches. Thank you again to everyone, much appreciated!

I really enjoy the IHO cm7 flavors, all of them.
I advise giving one a whirl, froyo just doesn't compare to gingerbread for my personal use.
They use more battery than harmonia, but the features! the features!

if you're financially solvent, I have a donate button in the sidebar... I like to help people out, but my woman really appreciates it when I get more from helping than warm fuzzies.
the thanks are appreciated, though, and if your income is like mine, don't send any money
Well if a promise is worth anything in this day and age, when I am slightly more financially stable I'll send enough for a six pack your way or some flowers so your girl won't mind you helping us for a while longer Thanks again and I'll load up CM7 now
Well easy come and easy go back to a new LG screen. So after managing to get the recovery working i went to flash CM7 on the Optimus using information here http://androidforums.com/optimus-v-all-things-root/366620-cm7-installation-my-optimus-v.html Anyway I am now experiencing this problem, I get stuck back at the lg screen again. I did wipe the cache data system 3 times to be safe before flashing the rom and i only have access to emergency mode and this screen ( regular boot and recovery mode come up and end the exact same way ). I'll explain what i see step by step...
1. The black and silver LG Logo
2. A green Android guy next to a box with arrow coming out and these words come up on the screen. " with out the numbers of course "
(1) Android Recovery
(2) Do Not Pull Battery
(3) Formatting Data:...
(4) Formatting cache:...
(5) Factory Reset...
(6) Rebooting...
3. Then reboots back to the black and silver LG Logo screen.
4. Finally stops and freeze's up on the screen with a pinkish/reddish LG symbol with LG next to it and www.lgmobile.com written underneath it.
Question being is this some sort of recovery boot loop? And if it is what can be done about it? Furthermore many if not all files on the phone so far seem to be " read only " .... well i guess I'm ready for round two!
I picked up this device from walmart for $29.99 with the intentions of learning some new development stuff.I
thought for 30 bucks there's gonna be a lot of these little "duallies" running around why not a cheap candidate?
So far as i can tell there is little info found about this device so I'm looking to collect what little is known about
it in one place in hopes to get a jump on it. First things first, I am responsible for my own actions as you are yours.
If your not sure ask or simply dont do, some of this stuff can brick your device!

finally a dialogue that states sucess.
***ISSUES HAVE BEEN REPORTED OF LOSING RECOVERY OR THE ABILITY TO ENTER IT AFTER
A WIPE AS WELL AS PROBLEMS BACKING UP AND OR RESTORING.
I have "injected" twrp manager into the system using titanium backup (link2sd will work also). This seems to
prevent any issues I have read about previously mentioned. Also I have successfully preformed backups as
well as restores, both before and after wiping. I have not figured out how to enter twrp recovery upon boot
yet, so be careful of what you do!
*SAFE TO REMOVE APPS*
yet to come
I use "titanium backup" from the play store, still trimming.I can get it down to about 230MB
available "free" ram at the moment but not consistently.
Ok had an issue with a task manager improperly reporting free available ram... true availability was
around 150mb free. There are apps that have to be replaced when removed, for example a launcher
for a launcher but some do not. Again I'm still trimming and experimenting, right now my system rom
around 244mb free. Most every thing I have done has been on the phone its self without the need of a P.C.
*STOCK BACK UP*
Yet to come
Any candidates for a true stock rom? Ive hacked the crap out of this one so far without the need of a back up... i know tisk tisk tisk!
I'm going for a debloated deodexed stock rom, hopefully!

The only ones I could find that actually work. The Verizon drivers mentioned for the g2, not surprising since it runs on vz towers!

I've got a few of these that are bootlooping. They show the LG logo, and then TracPhone Wireless splash screen infinitely in a loop.
Two questions.
1 - Is there any way to recover them? I'm hoping for some sort of a dev tool that I could flash a stock image or something (like Odin is for Samsung phones)
2- When these phones started bootlooping, I installed TWRP on the other Fuels that I have, thinking that I didn't want it to happen to them. My understanding of the TWRP that's installed from TWRP manager doesn't flash a modified boot image, so you can't enter TWRP from a powered off (or in my case, bootlooping) phone. Is that correct? I flashed a custom boot image from elsewhere that allows me to tap vol up at the LG logo to boot to TWRP. Any idea if this is enough of a safeguard to in the even of similar boot loops?
Any chance you know how to get it in diag mode? I need to connect it to DFS but can't without diag. Thanks for your help!

My apologies for the delayed response. I have a lot going on in life.
As for recovering them, use the device you have closest to stock to make a backup. Do this before you attach your account or put any thing in to it after a "fresh wipe". To the best of my knowledge there isnt a tool like odin available, i could be wrong though. You can push a back up to the looping devices via adb. in order to do this you must have previously enabled usb debugging. The instructions are available on the web, i my self dont know how to do this. If you can establish an adb connection im sure you can command it to boot into twrp. For setup and testing use one of the devices that doesnt have a problem to establish adb. There is a little info on another thread i created about investigating the boot process the link is in my signature for the defy. Please be patient with me as i have two jobs and a single father, im not a hacker or developer. just a normal guy that is fascinated by my little robot willing to learn any thing. now that I know this thread is becoming active Ill monitor a little closer. Also if there is any thing i can help with ill be glad to do so. Im wanting to get a second fuel just for dev and learning purposes.
Recovery
Is there a way to access recovery on the lg fuel? I am stuck in a boot loop because I disabled the home screen service as well as other things that I did not pay attention to. I do not have a custom recovery installed.
I've never been able to boot to recovery by way of button press. Seems like there's a way to get into boot loader mode though. Just can't remember off the top of my head, I'm at work now and don't have the fuel with me. I'll see what I can figure out in a few hours when I get home. In the mean time you can try button combos upon boot to include the home button. If we can get ADB talking to it there's a chance I can send you copies of the files needed. Give me more details of what you have done just before the boot looping.
Sent from my ALCATEL A564C using XDA Free mobile app
I bought the optimus fuel a few months ago and i've been using it primarily for a music player/run keeping devices during my jogs. I turned off mobile data and i've noticed that i still see signal bars on the top notification area - does this mean that the radios are still on?
I was wondering if there was some way to completely disable the cellular radios so that i could conserve battery life inbetween days where I don't run?
Thanks!
This is a pretty cool app....
https://play.google.com/store/apps/details?id=com.latedroid.juicedefender
Airplane mode and then turn WiFi back on does the trick. "Radios off" = ton more juice
Has anyone found out anything else for this little phone? I have the LG Optimus Fuel. Had it for a few months now. I rooted it as soon as I got it and uninstalled a few system apps like the LG keyboard, the default SMS app and Chrome along with 2 or 3 other Google apps. It's still running fine.
I installed TWRP recovery and a custom boot image so I could boot into recovery by pressing the up volume button. Works great. I made a full system backup and saved it to my external SD card and saved it to my Debian laptop.
Right now I'm just looking for a custom ROM for this little phone but can't find one. I'd love to get Cyanogenmod on this phone but there are none. I'd port it myself but I'm not able to at the moment.

I'll expand on the above link because no one can view all of the info in that thread w/o registering for that site [PITA].
Load towelroot (www.towelroot.com). Upon running towelroot, press "welcome to towelroot v3" 3-times (quickly). Change 1337 0 1 0 4 0 to 1337 0 0 0 4 0 (change only the ONE to a ZERO), click "make it ra1n" and you're rooted. :good:
This was verified on an L34C running Android 4.4, Kernel 3.4.0+, build KRT16S.L34CV10c, Sw ver L34CV10c.
YMMV; IANAL
My apologies for the inconvenience, I was unaware for the need to register.
What I would like to do with the L34C is find a ROM with all the phone functionality removed, and few to no Google Apps (let me just add the ones I need). I am not planning on using it as a phone (I still have my old Casio flip-phone, need nothing else). My intention was to experiment with creating a PalmPDA "replacement", something small to carry around for addresses, notes/memos, calendar (you know, the stuff you used to do on PalmOS), and in addition figure out how to do record-level synchronization **locally** (as in I don't need to send my data to some dirt-floor shack in Bangalore just to have it sent back to a device 2 feet away from my computer). Additionally, would line to use it as a basic portable media player. Essentially, trying to re-create the Palm LifeDrive on Android.
To my knowledge there are no roms available for this device. Your best bet in my opinion is to remove apps 1 by 1 after rooting. Google each and find out what the risk and severity of removing them are. I have donated my device to a less fortunate fellow employee. So as of now I'm unable to help with testing. This method is what I do for all of my devices until I'm finally happy with its performance and functionality. Think of Android as the swiss army knife of the computer world, you can do just about any thing with it, you just gotta figure out what tools are useful to you and the ones you can do with out, then you gotta ask Google witch ones Android can function with out. I hope you find what your looking for in the little robot, its a really neat world inside there!
I hate to bump an old thread but, I also don't it necessary to start a new one, at least not yet anyway but, I too am looking for a way to flash stock ROM. I have LG34Cs to use as a reference..
Where is the link to exposed framework at for this phone?

Broken as in doesn't boot into recovery. The phone will still boot into android, assuming you have a working system, and within android with root you can flash a working recovery image over a broken flash with the dd command on the twrp device info page (twrp.me/lg/lgoptimusfuel.html). So no real risk of brick, just possible inconvenience that might require a battery pull.
I built twrp 3.2.1 with same sources but I have not tested it since my battery seems to have completely died and the phone won't boot with usb power alone.
Here is link anyway in case anyone is interested:

You need to wait 40 days to be T-mobile user if the phone financed or lease, but you can unlock it right away if you purchased the phone out right without contract. I did it and use it on ATT network with no problem. Thanks to my buddy @markbencze that confirmed it in HERE and @Warrior1975 that also confirmed it in HERE

[SIZE=+1]Q8: Am I required to backup my ROM before flashing anything else?[/SIZE]
No you're not, but it is definitely a good idea and always recommended because if you don't do a backup and then something goes wrong, it means that you'll lose all your apps, data etc. It just saves a lot of hassle.
[SIZE=+1]Q9: How to get a logcat if I'm asked for it?[/SIZE]
Here is a link for learning how to make a Logcat[UNIVERSAL][LOGCAT]How to get & read a logcat/ Troubleshoot your own issues!
[SIZE=+1]Q10: What does MD5 checksum mean??[/SIZE]
MD5 digests have been widely used in the software world to provide some assurance that a transferred file has arrived intact. For example, file servers often provide a pre-computed MD5 (known as Md5sum) checksum for the files, so that a user can compare the checksum of the downloaded file to it. So this tool are to make sure that you would get same file as the developer uploaded file. Download MD5 TOOL CHECKER
[SIZE=+1]Q11: What is the best ROM/kernel/modem??[/SIZE]
Honestly, there is no "best". It's all based on personal choice. For example; I may like heavily customizing my ROMs where as you may like it to look at stock as possible. The best thing you can do is to just test out different ROMs/kernels/modems and see which you prefer.
[SIZE=+1]Q12: How do I restore a Nandroid Backup?[/SIZE]
Enter TWRP recovery mode again and look for the ‘backup and restore’. Select restore and everything should go back to normal in a few minutes.If you choose the ‘Advanced Restore’ option, you can select which component of the backup to restore – like the boot, system, data or cache .... Reboot to system. Your system is now restored and is exactly same as the time when the backup was made.

I've noticed that Google Now opens kind of slowly on this phone. You may start typing in the search bar, then it will reload and the keyboard will disappear, then you'll have to tap twice to get it back. Finally then you can type and search. I'm just wondering if this is the app or is it only on this phone that it does that..
I haven't flashed a ROM, just rooted the odexed stock ROM.

Been having some bluetooth issues lately. A device will pair then suddenly music will stop playing through bluetooth and play through speakers instead usually after a few minutes, even though the device and phone are still paired. I have seen this occur with multiple bluetooth devices and across 3 different roms. Any ideas?

I've tried stock, EYG Kernel, and the mods by warbeard_Actual. Same issues with all. Usually the issue shows up after a few weeks of usage in each rom, so I doubt it's hardware failure.
Edit: I've figured out the case. When my data connection drops, my bluetooth seems to flip out too. Which brings me to another issue. I've been having data drops close to every 30 minutes now, sometimes more than that. My family who is also on tmobile are not having these issues, so it's no issue with the towers. Not sure what's causing my data drops.

Have not experienced this issue or seen any other posts about it. Are other people getting double texts from you or just her? Have you tried another messaging app to test and see if that also replicates this issue? I always tell people to use Textra for messaging. Maybe try that or any of the other countless text apps.

Hello to all,
Respected members I have a LG v10 T-Mobile version with MM 6.0 stock version. I bought the phone today only. I have rooted many phones without any issues or trouble. Today when I used the method described in this thread [ http://forum.xda-developers.com/tmobile-lg-v10/development/tool-t3283944 ]. Now the problem is that I followed all the instructions up to the letter & everything was going ok.
I clicked the install.bat file the phone rebooted in download mode then it displayed that welcome to fastboot & there were a few options. On pc it in the CMD window which opened when I clicked install.bat file
which was present in the zip file I downloaded from the post it was displaying that waiting for device for I think may be 2 or 3 minutes. The it closed after 5minutes & I was seeing a black screen with 2 options with fast boot heading on top. The first option is to press the power button for 10 seconds to restart the phone or press fast reboot from adb. The problem is that I clicked both up & down volume keys after keeping the power key pressed for 10 seconds or more but nothing happened. The screen stayed for atleast 40 mimutes. Now the problem is that When I took the battery out of the phone to restart it booted & then after
lg mobile logo it displays that software not Recognize or Recognition failed. Can anyone please tell me what to do or that it is bricked or not. At the moment there is no bootloop or anything else. The phone is still connected to the pc with usb cable & is in firmware update mode. One more thing I wanted to respected members is that can I remove the phone or not. The phone is connected since 3 hours. I am at the moment download original stock firmware for T-Mobile v10 which MM 6.0. Any help or suggestion is greatly appreciated.
The phone booted to main screen & everything works fine. I also did a hard factory reset. It starts now but the only thing is that it displays that Phone software cannot be checked for corruption. It displays this for atleast 7 seconds & then the boots normally. What should I do. Should I flash the stock tmobile MM6.0 again through LG flash tool. PLease any suggestions r greatly appreciated.

Looks like the thread you used was for lollipop rather than Marshmallow? Sounds like you got it booting up now tho, so if you wanna root, jjst make sure to use a guide for rooting Marshmallow 6.0 [emoji106]

I've got a fun one.
I'm not sure what happened exactly, but after failing to install a kernel for 6.0 MM for my V10, I've lost a bunch... But still have a perfectly working phone?
fast charge, Fastboot, ADB... LG Up and LG Bridge don't recognize my phone anymore, and Windows 10 reports it as "Unknown USB Device (Device Descriptor Request Failed)" in the Device Manager.
I've tried multiple PCs, multiple cables, tried it on my Raspberry Pi and MacBook Pro too... No dice.
I still have TWRP working, I've still got my root going, and I do have xposed framework installed...
The heck did I do that I can't seem to undo?! Help!
Can someone please help me? I just got a T-Mobile LG V10 off eBay. It said the phone would just reboot and apps were crashing. His wife was due for a upgrade so she just got a SGS7. Will I got there's phone working I unlocked the bootloader but am still having some trouble flashing TWRP. But my real problem is that the phone has no sound and the mic isn't working. Everything else works great. Even vibration.
Any help would be much appreciated!
Thank you!
Any Way Out of Brick?
Hello guys I really need your help please. My LG v10 h901 bricked and it was on Tizen v5 custom rom, prior to that it never gave a problem - not even once.
I just received a call with my phone while driving and after a while? I realize no activity. I check & see that it is stuck on the "your device software can't be checked for corruption"
If I remove the battery, put it back & connect the charger, it charges & shows charge progress.
I can get into the factory reset using hardware keys but I can't get to TWRP.
I removed the sdcard and everything seems to be intact without corruption.
There was this one time it got in for some few minutes then restarted to verification stage.
I can get into download mode but in the device manager I see LGE AndroidNet USB Serial Port, It also shows up as LGE AndroidNet USB Modem. I've tried many things including flashtool, lgup and uppercut to no avail.
It doesn't overheat.
Bootloop or just maybe os/recovery failure??
I've tried everything here and on several websites to no avail. I thought of any modification I made to the phone prior to the problem & realize the evening before the bootloop, I installed "Swipe" & "All in One Gestures" to get full immersive look.
On the swipe, there was a time I got a warning & cos I was driving I believe I selected Ok.
Today, I was doing the same setup on my G3 then the warning came up and I read it carefully & selected cancel. I have a feeling that's my problem (it isn't the expected LG bootloop).
It is still stuck on the verification stage . When I checked on flashtool, I realized is no IMEI.
Tried to use fastboot to flash recovery.img boot.img aboot.img and laf.img I got from the tot I flashed TWRP with but it isn't seeing the phone.
Thanks Guys!!!
NB:
Got fastboot to work, see device and reboot command works but all other commands to erase or write images (boot & recovery) had error FAILED(recovery: unknown command)

I no longer have this device and cannot be much help but i do wish you luck
This was 6 devices ago for me, aside from switching to Samsung devices and now the Google Pixel XL, I have no idea how to fix that issue. Sorry.

Hey all,
I've never rooted a phone before so since I have a spare model, I figured I'd give it a go.
Hearing about this forum, I checked it out and was sent to the Sony site. I understand I needed to unlock the bootloader first, which I did and can confirm I get that alert as my phone starts about it not being safe.
Hint for future readers: don't do this in a virtual environment, I had issues doing this until I used an actual computer and not a VM (mods and folks with more experience: feel free to correct me on this or shed some light). To be clear, I have a separate host running Proxmox (Type I hypervisor) and was able to forward my USB connection to test with ADB and such. I do most things in a virtual environment to not mess up my physical computer.
This was all done last week. Well today, Monday, I decided to continue with my rooting excursion, only to run into the issue I am currently facing.
After many, many Google attempts and following whatever links in this, I finally found this link. Well, I was within a VM, downloaded the linked flashing tool, and ran the first two commands:
- adb devices
- adb reboot bootloader
After doing this, my phone turned off and I wasn't sure what to expect, so I pressed the Power button to see what would happen - nothing. So then I remembered that Friday I was having issues communicating with my mobile phone in the VM to unlock the bootloader in the first place, so I figured I'd try to move it to my physical computer....then I was stuck on a reboot cycle!
To be clear, my issue is that I am stuck on a boot loop. It prompts the error of the device being unsafe, waits 5 seconds, then displays the Sony splash screen. Rinse, wash, repeat; same thing.
I have a Sony Xperia XA1 (G3123) model.
Can anyone shed some light?
Am I screwed?
Please halp!
I dug around a bit more, found this link but the issue is that I cannot boot into anything, at least not that I'm aware of.

Hey @keifus.rahn for following up.
I did find that thread after continued poking, which I am still checking now. And I eventually made a post on there just now discussing my current dilemma.
I downloaded the Flashtool but didn't understand how it worked, nor do I still yet. I tried debugging it and the issue is that the "java -version" call doesn't work within the directory's own structure. I do have java installed on my test Linux VM though.
Past that, I tried with the latest boot.img as well as the recovery.img that I found. I think that the build numbers are off, or maybe I am just not understanding where I am lacking.
You can look at the bottom of the last page for a breakdown of what I did:

I've been getting help on this over at Hovatek, but it's extremely slow going; I first posted there on December 11 and it's still not resolved. This phone is a former Lifeline phone, and I've been trying to get it rooted so that I can use the Tello SIM I obtained. The problem the phone was having is that it refused to do any updates, so Tello's troubleshooting as to why it wasn't detecting the SIM was completely halted.
I did finally get to the point of rooting it. The major problem I have now is that it will only boot to fastboot mode. I can get it into recovery mode, but I get the dead android with "no connection" under it, and I've tried everything the internet has suggested to get past that, and it won't. Additionally, any fastboot command (apart from "fastboot devices") I try in ADB returns "FAILED (remote: 'unknown command'). I don't know how to get it into EDL mode from fastboot. I've tried every button combo possible, and the only one that does anything different is power + volume up, which changes it to a bright white screen. At this point I just want to do a hard reset so I can take another go at the rooting process, but the phone doesn't seem to want to allow me to. I would appreciate any help with this; I don't have a working phone at the moment because of these issues.
https://forum.xda-developers.com/t/trouble-rooting-umx-u683cl.4518007
Yes, that's my original post from back in November. That post is no longer my problem, though I will set your response there aside for when I hopefully get the phone to do anything besides fastboot.
it's clearly same topic, you must not open new thread. add your second post to previous one so mods can delete this thread.
It's clearly not. It's the same phone, but a different problem. The old post was seeking help with rooting it (and got no action, you may note), this one is about getting it out of fastboot mode so I can reset the damn thing and try again.
you bricked that device as a result of trouble with rooting. all info belongs to the previous thread, so others can read the history that caused this situation. I am not arguing any further here. answer in other thread and close this one.
