Hey all, I figured it was time to make a post and see if anyone could help figure out what I'm missing.
So I recently got my G2 and rooted it, then I installed Team Win Recovery Mod (on accident, actually. Was intending to install Clockwork, but figured it wouldn't hurt anything and it was working fine). Anyway, moved on to install Cyanogen Mod and gapps following the usual factory reset -> flash from /sdcard/ approach. Unfortunately on reboot, it went into fastboot mode.
Since then I've read a ton of stuff about fastboot, and I've reflashed recovery, boot, and system a dozen times, but I'm still stuck in fastboot mode. I've grabbed the CWM for LG G2 (AT&T) from http://www.clockworkmod.com/rommanager and the latest stable Cyanogen Mod from http://wiki.cyanogenmod.org/w/D802_Info. Sadly everything I've seen just tells me to do what I did - reflash recovery and tell it to reboot. I've also tried the "volume down + power until logo, then release and re-hit" method of getting into recovery mode, but the logo is present for literally less than a second, so I just end up back in fastboot.
Perhaps I need to find an flash a stock OS first? The thread on returning to stock firmware scares me :/ http://forum.xda-developers.com/showthread.php?t=2432476 Edit: I gave in and tried playing with this anyway. No good, I can't get the phone to enter "download mode", no matter what I do, it reboots into fastboot.
Any ideas?
Edit: The flash method I used for TWRM: http://forum.xda-developers.com/showthread.php?t=2449670
Edit2: This seems possibly relevant. When I do "fastboot devices", I get "? fastboot". So something is wonky in terms of its detection. But all the commands seem to be getting executed fine...
Edit3: Finally a potentially useful piece of info: If I flash the boot image extracted from the Cyanogen mod zip, then run "fastboot continue" I get "ERROR: Getting device tree address failed". Which is the same message I get when trying to remotely run a boot image without flashing it. Possibly related to the "?" in the "fastboot devices" listing above? I switched to Koush's Universal Adb Drivers, but no change.
Pretty please?
I find it hard to believe I could manage to brick a 2 week old phone just by following the guides posted here
Well, I still have no clue what went wrong, but I was finally able to make use of the reset to stock thread. It was strange and scary and at no point did I really have any idea I was hitting the right buttons, and at the end it said it failed... BUT it rebooted me into a fresh install, apparently even unrooted! My problems along the way appear to have entirely been related to actually getting the phone *into* download mode since I couldn't get it to actually turn off. Once it ran itself out of battery and turned off, I was able to enter download mode while reconnecting it to power.
No to decide if I want to try installing a custom ROM again, or take this as a sign...
Who am I kidding. *re-roots phone and pulls up the mod threads*
Seriously need help.
Didn't do anything unusual that I normally don't do, I flashed a different kernel because PAEK was eating too much battery and now all of a sudden my g2 will only boot into fastboot. Can't boot into recovery or anything, won't recognize adb commands, nothing. It sits at
[640]Fastboot mode started
[690]udc_start()
and won't move. I gotta have this phone up and running soon. Please help
Thanks
EDIT---MANAGED TO GET INTO RECOVERY....somehow.... and restored a recovery image. Fixed for the time being... mods can delete this thread
I have the exact same problem.
How have you managed to get into recovery?
Please give me a hint!

================================
Hello,
This afternoon, I was preparing to flash Oxygen OS 2.1 through twrp but I wanted to make a backup first. Attempting to load up twrp by holding Vol- and Power, my OPT flashed the starting frame of the boot animation for half a second before turning off. This repeated every 5 seconds. I could still boot OOS normally at this stage.
I decided to reflash twrp so as to make the backups, but on attempting to flash it, I saw that my bootloader was locked. So into fastboot mode I went, but trying to unlock it, it did the same as trying to get into recovery. As soon as I sent the command, "fastboot oem unlock", the screen went dark, flashed the starting frame for the boot animation, and promptly when dark again.
I now can't boot up normally, nor can I enter recovery. I can access fastboot mode, but I can't seem to make any changes.
I've attempted to use this solution as well as several other similar ones with no success.
I've had my OPT since 17th of August with absolutely no signs of trouble until this afternoon.
To me, it seems like it could be a hardware issue, but I'd hope it would last more than 40 days.
Any suggestions?
Thanks.

What were you doing before it occurred? Perhaps we can work out the cause.

I'm not sure what I was doing, I was going to flash different ak kernel as my wifi didn't work.
HOWEVER
I read someone suggesting if you still have bootloop after trying the qualcomm recovery tool, try booting to fastboot and use: fastboot continue
my opt booted nicely to hydrogen os and after I shut it down it no longer bootlooped and I was able to get to recovery.
I'll post this to your reddit thread too, maybe it might help somebody one day, hopefully this works for you too

Mate! that worked for me too!
However... It only seems to skip the bootloop for that power on. After power off, it returns to the boot loop. I also still can't unlock the bootloader and can't access recovery.
But at least it can boot into OS with fastboot continue!
Thank you.
Weird, after the first successful boot I rebooted and a chinese menu prompted me if I wanted to unlock the bootloader, and I did.
Maybe you should try different recovery packages.
But I'm glad to hear you at least got past the boot loop

Can't flash a new one since the bootloader won't unlock :/
I guess the phone is in working order at the moment, I just can't let it get turned off without my computer next to me...

Nono I mean different qualcomm recovery packages, the ones with MSM8994DownloadTool, I also replaced the stock recovery in the qualcomm package with twrp just in case if that matters

Ahh, do you mind linking me to the one you used?
I think I used this: https://mega.nz/#!EsNQHKab!ifATzg4rxxBniPad0iyxANqlN8cZpUx2MVWaZgEhrD4
but it might have also been this: https://drive.google.com/file/d/0B14IjYN3PtxcSlJ5aGQxX3JERHM/view?usp=sharing
It's also worth mentioning I flashed both a few times before I tried the fastboot continue command so try both a few times and see if that helps, also I replaced the stock recovery with twrp in both recovery packages before flashing.
Edit: And best of luck, I'm rather confident your OPT is going to work properly again.
Boot Loop
I got the same problem.
Phone is rooted and i can't unlock it in cmd, just reboot itself when i try it.
The only way for me to even start the OPT is to (volume+ and power), to get to fastboot mode, then run "fastboot continue" twice in cmd.
If i reboot the phone it get cought in a boot loop where i can see the logo, reboots about every 2 sec.
Is there a solution for this? I've been searching 2 for two days now.
I don't care if i have to reset the entire phone.

And I'm guessing you have tried the qualcomm recovery tool?

I got TWRP installed but its unreachable, volume- and power ends in boot loop.
I can´t install anything when the phone is locked.
I even tried a Factory reset, boot loop and no change when i got it up again.

Yeah but the qualcomm recovery tool that we discussed on the first page?

I finally got my OPT working again, tried Qualcomm recovery tool, wasn't able to complete the "MSM8994DownloadTool"
So i downloaded "A2001_14_A.03_150805" in a guide from technobuzz.net/unbrick-oneplus-2/
A similar but it does a entire wipe of the phone, nothing left at all. WARNING!
But i was okey with it.
Well the phone was in Chinese when it was all done but to change language was no problem.
I finally managed to solve it on mine. I had been cautious over the past weeks to not let it run out of battery or get turned off while away from my computer as
Code:
fastboot continue
was the only way I could get past the boot loop.
My core issue to solve was that I couldn't get it recognised as the USB Diagnostic 9006 under Ports in Device Manager. I installed the driver from here manually by right clicking the /qcser/x64/qcser.inf file and selecting install from the context menu. Then, I powered off my OP2. While only holding Vol+ (not power or Vol-), I plugged in my OP2 to the computer and it was finally recognised as the 9006. Then using the recovery tool from the prior link, it installed and rebooted my OP2. The moment of truth was when it rebooted and didn't enter a boot loop!
Then with the Chinese recovery prompt, I selected the top/first option and it brought me to the welcome/first setup screen of OOS.
It wiped the internal memory, and installed OSS 2.0.2 (don't know if coincidence or not as that was my prior OS as well). Now to install twrp and update to the latest OOS hopefully without a hitch.
Happy to finally know it wasn't a hardware issue like a failed eeprom or a dud nand controller as my prior phone (Samsung Note 10.1) died to a failed nand controller as well.
Will update with news of twrp and OOS, but I feel that should go smoothly now. Thanks to the others that helped in this thread too!
Yeap, all good!
Flashed official twrp through fastboot and batch installed OOS2 through 2.1.1 patches and SuperSU. Everything working like new!
Phew.

Is it recognised as a USB Diagnostic 9006 in your device manager?
Hi GusGold No its 9008
Hi!
The exact reference of my phone is this.
Please guys i need some help with this one. I was trying to get a custom ROM for my phone, so I started following this guide link. I got to flash TWRP via SP Flash Tool and then I rooted. Then, I got the MIUI ROM, and flashed via TWRP, wiped dalvik and everything as usual. Then it got stuck on boot, but it reboots too fast I mean, almost like the power button was being pressed all the time. So, I can't enter to TWRP, if I try to enter fastboot it reboots and I don't have enough time to detect it on my computer.
What could I do? Please I appreciate your help, I don't know what else to do, I have heard about some J-tag connection or something like that?
Thanks in advance.
Were you ever able to figure it out and root the ZTE blade a510 properly?

Sounds like we're in a similar situation, although I can access Bootloader and Factory Recovery, I can't load ADB or Fastboot commands. I was trying to load a 9.0 ROM as well (StatixOS). Hope you find a solution.

I decided to just go out and purchase a Galaxy S8+. I am planning on opening up this phone and see whats up with the volume down button. If I can fix whatever is wrong with that I will try to flash a stock image and use the bootloop fix. i'll keep you updated :good:
