[Q] Stuck in FTM Mode?

Hi folks,
My wife dropped her 2-week old Nexus 4 which caused part of the front glass to crack and portions of the touchscreen to be dead, so we had to send it into LG for repairs (at quite a price tag). Fine.
So we get it back, I turn it on, and it's in something called "FTM Mode" (file transfer mode, I think)? I can't seem to get it out of it.
Things I've tried:
Rebooting (have to hold the power button down for 5-10 sec).
Factory data reset (the settings are available through the notification menu in FTM Mode).
In recovery mode:
[*]Start (goes right back to FTM Mode)
[*]Power off (duh)
[*]Restart bootloader (gets me right back to the same screen)
[*]Recovery mode (gives me a little android with its stomach open, a red exclamation point, and says "No command.")​
I attempted LG support, but they asked me to do a few of these (after asking me to hit the "home" button...), then told me to mail it back to them because they probably have to flash it.
So, the obvious question: how the hell can I get out of FTM Mode?
Secondary question: if none of the above worked and I do have to flash the OS, can I flash it myself to default Jellybean? Any idiot-friendly step-by-step guides out there?

Here you are! (I was the one talking to you on Reddit)
Since you can get to fastboot you can just flash the stock image files and you should be fine! The toolkit is in the original dev section but you cannot download the images from it anymore. A few people here have the images though so hopefully someone will pop up with them shortly

I have located an image... just need to figure out the fastboot stuff. I'm not a terribly adventurous user, you see.

No worries! You can use the toolkit without knowing fastboot, I just recommended learning it in case you ever need to flash without it. I believe after you download the toolkit there will be a folder you can place the stock image into then you can use the toolkit to flash the image from that folder. I'm not 100% what folder that is though but I believe the name makes it fairly obvious if you look for it

Unfortunately, I haven't even been able to install the bloody USB driver, so fastboot/adb can't even see the device. I've described by problem here. I think the source issue is what LG did during repairs... the device is named "Full JellyBean on Mako" instead of something like "Nexus 4", so the drivers in that post aren't being recognized by Windows as valid for the device. At least that's my guess.

OK, got it all fixed.
This post was incredibly useful. Once I got the USB drivers installed and fastboot recognizing the device (oddly, adb wasn't able to), it was extremely smooth unlocking the bootloader and flashing the image.
Thanks!

For future reference ADB only works in recovery and when booted into android, never in boot loader. Bit glad you got it working

【Help!】Failed to unlock Bootloader of Nexus 4

I just got my Nexus 4 and installed SDK and drivers on PC. OK, so now I boots my phone into fastboot mode, I connected it to my PC, entered"fastboot devices" in command line, no problem, I can see the device with the ID.
But when I entered"fastboot oem unlock", the command line it says" FAILED <command write failed <Unknown error>>". And the phone stays in fastboot mode without any pop-up.
I use USB 2.0 ports on the backside of the computer. Also USB 2.0 on my laptop. None of them work.
I tried to factory set the phone, restart computer and phone, change to another computer, none of them worked. Maybe I should contact Google to ask for an exchange because mine can not be unlocked?
Any help is deeply appreciated.

Yeah, GOOGLE will be happy to replace your phone because you cannot unlock your bootloader!? Are u serious? Make sure USB debugging is enabled under developer options...

Only applies to ADB, not fastboot

Have you got the latest SDK files? Have you got the latest bootloader?

Hy There i finally got my nexus 4 two days ago, i tried to search Google about bootloader limitation if there is any? Im pretty freaked cause i previously used xperia S with bootloader impossible to unlock, due to a carrier lock.
So is there a metod to check if bootloader of my N4 is possible to unlock like in hidden menu *#*#4636#*#* wich i cheked but i dont know to what i should pay attention? or is there the other way to chek .
I know that unlocking and rooting should be possible in N4 but i hope u understand my concern cause i bought N4 trough carrier contract and a negative expirience with xperia s, thanx

No, a Nexus device will ALWAYS have an unlockable bootloader.

I don't know if anyone has said this yet, but are you sure you're in fastboot mode when you type: fastboot oem unlock?
that command only works from the bootloader, not from inside recovery or when your system is booted up.

I just rebooted into the bootloader mode, hooked it up to my computer. Typed
fastboot oem unlock
There was a warning just after, accepted it.
then I downloaded the latest TWRP (2.5.0.0) for mako (Nexus 4)
fastboot flash recovery name-of-recovery.img
booted into recovery, made a backup of my Stock rom, wiped /system /data /cache, used the following while in recovery
adb push name-of-my-rom.zip /sdcard
adb push name-of-google-apps.zip /sdcard
then installed both via recovery and rebooted into the fresh new custom rom.
If I had not installed a custom rom, and I were to leave TWRP into a non-rooted stock:
TWRP would instead warn me that it doesn't appear to be rooted, and if I would like it to place SuperSu on it, it would do so, and I would reboot into the stock system, launch SuperSu where it will ask me if I would like it to reboot into recovery and install the su binary. Which it does automatically, so stock-wise that was the cleanest way for me to get rooted on stock (with an unlocked bootloader)

By the way just as a recap.
fastboot works in the bootloader mode.
adb works in recovery and in normal system (with usb debugging enabled).

Nexus 7 2012 grouper Can't unlock bootloader

I have the afore mentioned Nexus 7. Have all the toolkits and proficient in adb. Get to the unlock prompt for the bootloader and press power over the yes option. It comes back up in bootloader locked every time.
I am in an endless loop otherwise. I can load to safe mode also.
Have the 4.23 bootloader and was trying to take the ota to 4.4.3.
Used two different aio toolboxes both with no luck. Tried to force load a stock rom. No luck. It just keeps booting back to how the tablet was before the update then reboots before you can do anything.

If you are proficient in adb like you state,then drop the toolkits.
What commands are you using? Does adb recognize your device?

Toolkits or cmd prompt the result is the same. Bootloader acts like it is going to unlock but doesn't.

I too have this same issue.....
Once I get the unlock screen (using tool kit) and select yes.... it goes to reboot, but the tablet never comes back on...
Once I turn it back on, I never get passed the "Google" screen....
The tool kit ADB see's the tablet and runs through the "unlock" yet it never takes....
I assume that USB debugging is not turned on... but I can't get the tablet to start it up to turn it on...
Been trying SKIPSOFT ANDROID TOOLKIT.
Can anyone help?

Try the other toolkit.

Yes... I have attempted to unlock the device 3 times...
I have used 2 different tool kits and adb fast boot....
They attempt to unlock the device.... but as the unit goes to unlock, it goes to reboot and the unit doesn't come back on... If I manually turn it on, it still shows the unit as locked...
When using abd, the unit does try and unlock and then when it reboots it shows that it unlocked the device yet the device still shows locked..
I'm at a loss right now as to what I should do....

That's a problem. (Not being able to unlock with fastboot can be a sign of corrupted bootloader/partition/emmc)
Have you tried to factory reset your N7?

[Q] Bricked and gone?

Pretty sure I know the answer to this, but before I finally through in the towel or rather my Nexus 4 against the wall... I will defer to the resident experts. So, I attempt to install Liquid Smooth 4.0 and after going into TWRP I did a wipe and installed it. I was running the previous official build of Liquid Smooth. I also install gapps for Lollipop. Everything began to boot and then the phone said something to the like apps are starting and it stayed on that screen for a full 8 hours. I went back into recovery and tried to restore from my previous Liquid Smooth. Exact same thing happened. After several attempts I did the unmentionable. I did a full wipe. I know it was a dumb*ss move now. My phone does NOT connect to ANY PC. Every time the PC says device not recognized. Now I have now OS. Only TWRP. I tried sideload, but computer does not recognize device. I bought usb-otg adapter, but found out that usb-otg does not work with Nexus 4. So.... should I throw in the towel? My phone now a fancy paperweight?
Many thanks!

Unknown Device... It is worth noting that I have used Wugs Toolkit and followed every set of directions to a T. This includes a PC that that has never had my phone in it before. Followed all the steps before I even tried to connect. Also, both PC machine indicate that I have installed the most update driver.

I have zero experience with that toolkit, but have you tired every usb port on your computer and possibly another computer? Your phone is far from gone, this just sounds like a driver issue to me. Is your phone recognizable in bootloader?
I don't actually have this phone but my wife does, as well as my brother. Just the other night my wife's was showing up unrecognized, all I had to do was swap usb ports on the computer.

I do if I understand the term correctly. I am at the android "start" screen and underneath the android it says
Fastboot Mode
Product_Name - mako
lock state - unlocked
Now what?

Connect it to your computer, and I assume you have fastboot and adb set up correctly. In command prompt type fastboot devices and see if your phone is listed, should give the serial and say fastboot next to that

Not sure if I know how to set up adb correctly... as far as fastboot goes.. I assume that is set up correctly. Would adb work if the PC doesn't recognize my phone?

Well adb is of no use here so I wouldn't worry about it. Is fastboot recognized?

Once you finish the adb fastboot setup, while your phone is in the boot loader screen you should be able to type into a command prompt "fastboot devices" and your device should be listed.

I'm fairly certain this is just a simple fix on the drivers on your computer, you have access to recovery and boot loader, your phone is far from gone. I'm out atm so I'll check in with ya a little later.

Open up device manager, look for the phone, right click and hit update driver, then hit let !e choose driver, then select from list, you shpuld see something along the lines of ADB interface. Select that and install and try fastboot devices in command prompt again.

I am pretty certain I have the proper drivers installed on 3 computers. Not a single one recognizes the device. I suppose it is possible that it is a hardware issue? If I can figure a way to the computer to recognize the phone I am certain I can save it. Right NOTHING has worked.

Stuck in Boot, fastboot locked, no adb sideload

Hello,
I have a Nexus 6P stuck during boot on the white google logo. Apparently it happened during an update to N.
I have attempted a few solutions I have found either on xda or on other pages but the gist of what I’ve attempted so far is thus:
I have tried to reflash android stock after obtaining it from google : https://developers.google.com/android/images (MTC19T) but the oem option was unchecked so “fastboot flashing unlock” returns with an error.
I have tried to apply an OTA update, again I obtained the file from google (MTC19T) , via the recovery > apply update from adb . But it fails. The error from the phone is:
Code:
E: failed to verify whole file signature
E: signature verification failed
And on the pc side I believe that the failure comes from the fact that my pc has never been connected to the phone via ADB, so it’s unrecognized.
- I have also tried to bypass the adb pc signature issue by connecting a usb flashdrive to my phone via a usb-c adapter but the mount /sdcard command doesn’t work.
I’ve tried a few more esoteric solutions, like booting into Emergency Download (EDL) but my phone just boots into the google logo and stays there.
A few informations on my device (according to the fastboot/recovery screen)
Code:
BL: angler-03.51
Baseband: angler-03.61
Product/Variant: ANGLER-ROW-WN1
6.0.1/MTC19T/2741993
Current Build Number: MTC19T
So, to summarize: Fastboot is locked and won’t work, ADB is unrecognized and using a usb drive pretending to be an sdcard doesn’t work and I’m working with a stock recovery.
I'm looking for a way to bypass the fastbook lock or the adb verification. Or (even better) for anyone here to tell me that I've been going the wrong way all this time and that the solutions involves three easy steps...
Thank you!

Try again but you have to use an OTA that is newer than MTC19T. You still may be able to sideload when recovery is in ADB Sideload mode. There is no way to unlock your bootloader. Make sure you are using a recent, known working copy of ADB/Fastboot. The problem many people can't overcome is that they never set up ADB before or used it on a few occasions, so now the phone is dead they can't get it set up correctly. When the phone is connected in recovery>>ADB sideload update, what returns when you run "adb devices"? Do you have another phone you can use to confirm your ADB/fastboot setup is installed correctly?

Download the Nexus toolkit and then boot into recovery and select on the toolkit "softbrick" , good luck. Private message if you need any help

Hi,
Thank you for your answers.
@v12xke For the OTA after trying MTC19T I downloaded and tried half a dozen images from Google. Previous versions, next version of marshmallow, a few of the nougat versions. The results were exactly the same.
As for adb I just updated my Android studio, and it's not the first time I've used these tools. The process of sideloading the zip always stops at 47% but I can see that adb and the recovery are communicating.
Fastboot devices also detects my device, but I don't have my computer on me right now.
@DavidSantos I already tried the toolkit but it just launched my phone on the Google logo and got stuck there.

Yes, I did that. The soft just makes my nexus reboot to the Google logo.

@v12xke: Looks like there are also more and more of those bootloader + recovery access bootloop. With sideload OTA fails...
@Hipstronaute: I have already seen one or two users with the same kind of problem and if I remember, nothing fixed the problem.
Good luck...

Might be a special edition Nexus 6P , oh well. Mine had the same problem and it worked just fine

That's too bad. Sounds like the storage memory going bad and the write process is interrupted when it hits that area. Thing is, I've heard the same OTA write failure occurring several times at 47%. Wonder what that means? Anyway sounds like @Hipstronaute is looking at a replacement phone, under warranty or otherwise.
