LG G2 shuts down during boot at random points - AT&T LG G2

I have an LG G2 D800, with stock everything; I did something either interesting or dumb, and now it won't boot. I never rooted it because all the instructions were for Windows, and I use Linux, and never found anything that explained how to do it with Linux, if possible. But I now have a a usable Windows (Vista) installed in a VM, so maybe I can do something.
Here's what happened; I hope someone can help steer me in the right direction...
I finished my AT&T contract, and decided to move to Project Fi. I got a Nexus 5X, and got an unlock code for my G2, which I wanted to give to my wife's brother in China. So, I needed to get a non-AT&T sim to enter the unlock code. Here's where I went wrong. I was curious about what would happen if I used the Project Fi sim, and since I wasn't rooted, I didn't think it would do anything bad (silly me!). Well, it did. It crashed, so I removed the sim and turned off the phone. Now, it won't boot. It sometimes just shuts down immediately, sometimes after the LG logo, sometimes after the AT&T logo, and a few times, it made it all the way to the login screen before turning off. Never further than that.
I did a factory reset, tried starting in safe mode many times, and sometimes it gets to a screen saying it's updating Android, but has never made it past 20 files before turning off. By the way, if it was reset, how could it update Android - wouldn't the WiFi need to be set up?
So, I'm wondering what might be wrong, and what might fix it. Obviously, I'm willing to try anything at this point, as it can't get much worse. The phone is in perfect shape, and would make a nice gift (or sellable item), so I hate to lose it.
I'm pretty technically inclined, but I don't know much about phone tech. I know Linux pretty well though, so I can follow directions without too much babying. Or, just point me the right direction.
It did go into download mode, but right now, it seems like it doesn't want to do that.
Thanks to anyone that can help.

HTC Touch Pro 2 Brick

Dear Folks at XDA,
I would like to ask for you help with my HTC Touch Pro 2. I recently tried to update it to the new AthineOS CHome TF3D WM6.5 Manila ROM v 1.0 and unfortunately I failed.
The problem is that my phone now freezes at the black startup screen with the Touch Pro 2 logo and the red codes at the bottom.
I've flashed the ROM several times before and never got this issue.
Due to the fact that the phone doesn't finish the boot-up and I thus I can't get ActiveSync I'm afraid I messed up my phone for ever.
Please someone tell me I got a way out of this, I'd appreciate it very much.
Greetz,
SjonSjon
umm.... I don't think you can change the firmware just yet on the CDMA version of the phone... if you used a HardSPL that's available in the Rhodium forums then you probably used a GSM specific ROM on your CDMA phone... not sure what to tell you other than making sure you read the CDMA forum before trying something so risky. Best solution, unless someone knows how fix your phone in it's current state, is to toss it under your car and run it over and try to cash in on the insurance.
Problem solved!
Hey guys,
I got my HTC Touch Pro 2 functioning again. Thought I'd post the solution for other people who might encounter the same issue. I don't exactly know what the problem was. I'm assuming a non-compatible ROM or something, but after opening 30 tabs in my browser and reading my eyes out I found that if you put your phone into bootloader mode and connect it through usb to your computer you can flash the ROM without using activesync.
So I turned my phone off, pressed the power and Volume Down button simultaneously and then used the Stock ROM upgrade software from HTC to restore my phone
This solution beats the hell outta "run it over and try to cash in on the insurance" if I say so myself!

I am glad you have recovered the beautiful device; and thanks for sharing a working solution.

Good job!
big thanks for solution.
You just saved my life!!!
Don't get our hopes up! This is the wrong forum. CDMA TP2s can't be flashed at all yet.
This was a life saver post so a quick bump for anyone that needs it.
I unlocked my CDMA phone, installed a few roms -- decided to go back to my stock rom default (which was Telus) -- reinstalled and bam -- bricked.
Well, technically it's not a brick if you can get back into the bootloader to reflash. So no worries everyone. If everyone reads instructions well enough we should hopefully see zero "real" bricks. Or at most, just enough to only build bbq pit rather than a house.
I think my phone is truly bricked
I was unlocking my phone (the HTC Touch Pro 2 <Verizon>) and I was using a Diamond unlocker (I thought it would be fine), but during the process there was a connection error and now my phone seems to be bricked. I can't get it to even turn on, get to a bootloader screen, or anything even remotely close.
The one odd thing that it does though, is when I connect it to my computer, it pops up and my computer recognizes there is a device there. In my Device Manager there is an unknown device called: Qualcomm CDMA Technologies MSM. I have tried every combination of two buttons, including holding down the reset button with all of them, but nothing gets me anywhere.
If anyone could help, I would really appreciate it. Let me know if you need any more information.
my cdma is rebooting endlessley i reflashed stock rom and evorything. it seriously dosnt want to work. its most sadness... i am cashing in on the insurence. but they are going to send me a refurb..
spend 600$ on a phone got inurnce i hope the used one dosnt fail me.

I did the same exact thing to mt TP2. Same outcome.
We have to learn somehow....
That stinks man. If you did, then your phone is truly bricked. You are going to have to get a replacement or switch to another phone because there is nothing you can do to get it going again. I tried everything possible and eventually just ordered a replacement. I have it now and it's working beautifully, but needless to say I am a little scared away from any more unlocking or flashing for a while.
If you read carefully you dont have to be scared of flashing
I was a noob some time ago but before doing anything I took care of reading and understanding before doing nothing.
lesson learned
By now I have flashed more than 60 times on 3 diferent HTC devices and all were a succes
Hope you get your TP2 working again!
I hope I can get there
Someday I hope to be a flashing expert, but until then I will take it slow and read carefully. Thanks for your encouragement. When I actually get money to pay for the unlock for my TP2, I will let you know how flashing goes.
How do you keep the phone in bootloader? Mine goes right to the press volume instuction screen. Other than that I'm stuck on the black name screen,also my usb will not register in device manager. This was my first try at flashing.

Holy hell, you're not lying. Thanks for coming back to post your solution!
This post saved me at least a few hours of frustration and ever worsening decision making.
So it's totally true???
this situation hasn't solution;
I was unlocking my phone (the HTC Touch Pro 2 <SPRINT>) and I was using a Diamond unlocker (I thought it would be fine), but during the process there was a connection error and now my phone seems to be bricked. I can't get it to even turn on, get to a bootloader screen, or anything even remotely close.

If anyone could help, AND PLEASE somebody tell me , that it can be save it

[Q] What Have I Done?!!?

Hi. This is my first time posting. I apologize in advance, im going to come across as a noob.
I got tired of waiting for google to get 2.3 to the N1 users. I decided it was time to unlock and root my phone, after all thats what it was designed for. Up until this point the phone was stock with all updates. I thought one touch root no longer worked. I dont know why i thought this. I used a guide to work through it. I cannot post links otherwise i would. ilikemygooglephone . com is where it came from
Everything worked according to this guide until I completed it and powered my phone on for the first time. I thought I was going to see a stock wiped nexus one...Instead I got shafted.
The phone reboots randomly. It happens quickly and unpredictably.
Notification bar will never slide down. If i try to the phone lags but never shows notifications.
No 3g
No wifi
The phone says I have no service (selected network tmobile unavailable) although I can still make and receive calls.
The sd card will not mount. I cannot access it on the phone. When pluggen into my laptop the phone will charge but wont give me the option to access the sd card.
At times the graphics are buggy and dont operate properly
There are probably other problems that i am forgetting but I think this says enough. Since i cannot access the SDcard I really dont know what to do.
Im sorry if this thread is in the wrong place or happens to be a previously answered question. I just really like my phone and I hope its not wasted. Can someone tell me what I did wrong or how i can get this right.
YEAH i noobed it.
I freaked out on the above issue for about 5 hours. Now I believe i have everything back to normal. My problem was i didnt load the proper superboot. Once i found the FRG83 one and redid the process using that instead it worked fine. Either i was using the wrong superboot or i had a corrupted download somehow.
Feels good to figure it out on my own though....i feel...less noob.....NAH

[Q] Unkniwn issue rooting HTC Aria

Hi guys, I'm having a problem rooting an HTC Aria that I recently acquired, and I'm not sure how to search for my answer. I guess Ill try to explain what happen as best as I know, since some things happened so fast I have no idea exactly what happened. Its also worth mentioning that I have no experience rooting android phones, but I'm not an idiot, so please don't be afraid to help because you think Im gonna be waste of your time.
I used the tool unRevoked with Reflash to inflict the damage. Things seemed to be going great, in fact at one point it even said this was a triumph. Somewhere towards the very end, it looked as if it complained about not finding a file on the sd. It was so fast I couldn't read it because I was looking at the computer at that time. Im not surprised it didn't find the file it was looking for since I had no sd card installed. The tutorial/procedure that I read was very detailed, so detailed that he sometimes took a minute to make sure the reader knew to double click the file to open it, yet there was no mention of absolutely needing an sd card for it to work.
Now when I re-run reflash, when I get to the point where you have to choose HBoot USB, it wont ever let me pick it. It just forces me to pick Fastboot or one of the other ones, spits out several lines of green text that is way too fast to read, then gives you the option to pick HBoot again. It never leaves this menu now, not by way of reflash anyway. I can still unplug and reboot my phone , and operate it like normal, but reflash wont go past that recovery menu. I did a factory reset, that didn't help. I also picked recovery on that menu. I browsed the options, but Im afraid to make another move at this point without some input. If someone could please maybe tell me what happened and how to proceed I would be very grateful.
Thank you

Sprint galaxy note 5 us

Hi guys. Ive been a long time subscriber and lover of these forums never really posted though. I need some help at the moment however, without sounding like an absolute complete noob. Here is my scenario... Bought a note 5 from my friend which he said wasnt working, noticed that some idiot (above mentioned friend im sure) tried to root it without knowing what they were doing jence tripping the bootloader and knox. I started playing around, with sprint sim and also with metro pcs sim inserted. At one point i got to the iot menu and i took a strp back and had to stop. Now i have never seen this menu even though i have been programming and coding since high school. Also, i am an avid drinker amongst other things and sometimes i will get so into coding or research and be surrounded by computers and tablets and phones all firing on different levels that i. Am not as focused on one particular thing enough. Sell this was one of those moments and after a quick overlook of what the menu had to offer i realized i should back off for the time being until i was sure. I did not use any dialer or #* or anything like that. My best guess is that it was something i did during the restart. Ive seen the pic if the menu im talking about online but no way to get to it. Someone help me out please. Im all about anonymity also so if you would like to contact me anonymously i can you can reach me on the bleeding eye site [email protected] or email me or even text me thank you.
Shut it off, then hold volume down, home, and power button to let it boot into odin mode/download mode. It will tell what type of phone it is, and u can flash the right stock from sammobile. And be sure to select the nand erase all option once your sure you got the right vsrision of the phone. Thats how my phone came back to life through many things, and after its back up you can try rooting again. I rooted via odin and thats how i installed my twrp also

Phone went back into boot loop, what should I do now?

Last week it started and I was able to fix it but with a different stock rom. I also couldn't restart it or else it would go back into the loop. It is a Metro PCS G930T. I had to flash it with T-Mobile firmware as the only Metro firmware was for the G930T1. Now I downloaded that G930T1 firmware, but I'm not sure if I would be able to do it as it is a different model. I just don't like the UI of the T-Mobile one and want my old one back. This is only the second time it restarted by itself since the first boot loop but this time it's stuck again. I really don't want to have to wipe data every single week. Even though most of my stuff is synced I still have to go through settings every time and set it up again. I don't know how Samsung gets away with this either. They purposely engineer their products to stop working after 1-2 years. Straight up consumer fraud especially when they refuse to fix it while still under warranty.
Do you have solid proof of this allegations?
what are you talking about? I am just trying to get advice on what to do, not get into an ethical debate.
You said: consumer fraud.
That's asking for help?
Stick to the point.
yes. stick to the point. stick to answering the main question. don't mind the rant if you don't understand it.
Are you an Apple fan boy?
Edit what you said about Samsung, and I'll answer you.
And go drink your milk and go to sleep. You must be a ten-year-old.
You come here to seek help, not to rant.
Rant in your own home.
Are you using any sd card? I had a bootloop issue due to corrupted sd and when i ejected it and reboot phone worked like nothing had ever happened
