Unlock Bootloader without Factory Reset? - Nexus 5 Q&A, Help & Troubleshooting

Is it possible? I've read that it isn't, but there have been methods in the past to unlock Nexus bootloaders without the use of fastboot. I was dumb and didn't unlock it right away.

Unfortunately, I don't think it's possible. Titanium Backup and upload to Drive.

Oops, forgot about that. You're hosed.

the only way this would be possible is if someone found an exploit in 4.4. The last time this was available i believe it was closed on 4.2.2 or 4.3

There's a way to make an adb backup (without being rooted) that backs up everything including app data. Kind of like making a backup image. I can't find the link now, but if you search around, there's a guide. You would then just have to restore from that add backup.
EDIT: Here's the link. I haven't tried this in a while, so I can't guarantee it will work, but its worth a shot. It wont mess anything up.

[SOLVED] Did I brick?

Hey everyone,
So I think I may have done something strange and i'm not sure how to fix it. Long story short, screen cracked, so I bought a new one and I used TWRP to backup my original phone. So now, i'm just trying to unlock and root, you know, the usual. BTW, I tried using ABD/Fastboot, which I never typically do, but I heard it was more efficient and whatnot so I thought I try. I think the unlocking of the bootloader went well. And I even think I flashed recovery properly. But when I tried to access recovery, it prompted me for a password.
I read on the TWRP site I was supposed to let the phone boot as normal before accessing recovery. Oops. So I tried formatting all the data on the phone and no I have no OS or any files to recover from and adb push keeps giving me "Device not found" and now I don't know what to do.
Help?
EDIT: In case anyone has this issue searching threads, I just used Wug Toolkit to flash everything back to stock and then used the same Toolkit to unlock and root. TWRP isn't going to recognize a backup from a different phone. To my understanding, there is a way around that, but I didn't look into it. Oh, and apparently, don't flash the EFS partition lol

Oh, that reminds me, TWRP wasn't able to mount any of the directories, it seems. I think it can, now, but I remember seeing those errors in the log before I wiped everything. Thanks for that suggestion, i'll give it a shot.

I can't seem to find on the internets which odin version is compatible with the Nexus 5. I'm not finding any hits to directly correlate and I don't want to damage further. Which one would you recommend?

Odin is a Samsung thing. Not LG.
What you'll need to do is flash the 4.4.2 factory image. Follow this guide: http://forum.xda-developers.com/showthread.php?t=2513701

OK!
So, I used the Wug toolkit to basically flash everything to stock, and then root it. I installed TWRP using the app and I tried using the app to restore from my earlier back up. So, it boots into recovery but nothing happened. Looking at the log, it says the TWRP isn't able to locate the files. Trying to just restore from recovery isn't helpful because when I hit "Restore" nothing pops up. As if the SDCard partition isn't being accessed. I can't see any of the files in any directory. Anyone have any ideas?
You need to let the phone boot into android before flashing a custom recovery.

Flashing the factory image erases everything. Such as backups stored on your phone.

Did you put the backup on the root of the sdcard? I think it needs to be in the TWRP folder. You should first make a backup of your current rom even if it's stock rooted.

Someone explained to me TWRP won't recognize a backup with a serial number from a different phone. So essentially, I will just have to forego it. I used Wug Toolkit to fix this issue and just flashed everything to stock and had the same toolkit unlock and root. Using ADB was a fail and cost me a whole afternoon lol

[Q] Is the N5 a sensitive phone?

Hi, I'm just about to root root my N5. I had already 2 htc phones and i rooted them without problems. But now I'd like to know whether there is something I have to pay attention about more than on other phone or is the Nexus 5 in general a "easy to root" phone which doesn't brick often? And I'd also like to know whether the warranty restores when gettin the phone back to stock?
Nothing is harder to brick than a Nexus.
There is a flash counter that can be reset if you need to warranty the device.
Sent from my Nexus 5 using Tapatalk
Nexus is easy-street to root compared so other devices. Very hard to brick it unless you load a rom that is not compatible, obviously.
When you go back to stock you can re-lock the bootloader and as the above guy said reset the flash counter.
Hope this helps.

There is an image of a padlock on the splash screen and also the lock status is listed in the bootloader. They change when you lock or unlock it. It's a simple fastboot command. This isn't an HTC. This is a Nexus. Whole different ball of wax.

Rooting my nexus 5 (questions)

So I am waiting for my nexus 5 to arrive (hopefully by end of this week or early next week) and I am pretty sure I want to root it. Coming from a rooted s3, there are just way too many advantages of Rooting that I cannot give up. So I have a few questions:
1) how easy it is to relock the bootloader for warranty purposes? Has anyone had to send back their rooted phone to Google and been successful?
2) has anyone here unrooted their phone successfully and sent it back to Google for warranty?
3) if I root but do not flash a custom rom, will I still be able to do Ota updates?
4) will simply uprooting the device (with stock rom) cause any unstability issues?
Thanks!

1) see the return to stock thread (sticky) in general
2) yes by following the thread in 1)
3) theres a great thread called "ota help-desk" in general that covers this. Its not a sticky but easily located with search
4) uprooting? If you mean unrooting, then no

generally, if its a hardware issue with your device, google will accept rooted devices to fix/replace. if its a software issue, theyll just send it back. ive sent a nexus phone and tablet in for replacement last year, both were still rooted, both still had custom recoveries, custom animations, custom roms, and custom kernels. they gave me no issues about the exchange.
Oh that's great to hear. Then why is known that unlocking your bootloader voids your warranty?
That's my biggest fear. If I unlock the bootloader and then have a hardware issue and cannot relock the bootloader, Will Google refuse to fix it?
Thanks for all the replies! I will check out those topics and videos.

LG will not procede the same way in country`s where you can`t buy the N5 i`am afraid and will say your warranty is voided because of rooting the phone.

if you buy the phone from somewhere else, it will void the warranty, but its easily locked with "fastboot oem lock". but through google, as long as its a hardware issue, they will take care of you.
I ordered the phone from the play store (in canada) so I assume all will be good.
Also to the link to an app to the play store, how exactly does that work? It seems like the perfect solution so why don't more people use it?

You can using CF-AutoRoot, but it's all a bit one-click which removes your learning curve and invariably ends with you bricking your device, so lets go the custom recovery route please

Yup, download the latest TWRP recovery, plave it i the fastboot folder and rename it to twrp.img. Place the superSU.zip file on the phones `s sdcard.
Boot into bootlader and type in cmd: fastboot boot twrp.img, twrp will boot (not install) and you can flash the superSU.zip file and reboot.

i got mine and never did power it on into the os once while unrooted. booted to bootloader very first thing, unlocked, flashed, then powered it in to the os the first time with custom rom/kernel
adb backup was implemented for this exact purpose, though it seems to have mixed results for people. you could try it
As others say learn about your phone. ADB commands save it.
The number of stupid tool kits on the nexus 5 is out of hand. No wonder pple can't do anything. They buy a phone unlock it and flash the wrong thing and cry. Tough learn!

Unroot

I'm RMA my nexus so I tried to flash stock thru wugfresh kit but it gets stuck and won't do it . so I remember I did a back up as soon as I rooted my phone so I restored that . I unrooted thru the superuser app its self , I went thru advance options on the root kit and flashed stock recovery and then relocked my phone.
My question is if that's enough to send it back? Will they be able to tell I rooted ? After I relocked it it said it reset the flag as well so I guess that's good .
The reason I use tool kits because its easier and I'm nervous to try it without a tool kit.

Yes, you can but make sure you don't restore the EFS.. If you do. Then your new phone is SCREWED! That's why I never recommend anyone restoring backups of different phones!

Yes, everything looks peachy!
If you're not sure whether the tamper flag is reset or not.. Head over to bootloader and use this command : fastboot oem device-info
If the tamper flag is set to "true" then you haven't reset it correctly. If it's "false" then it's all good!
BTW, why are you RMA'ing the device?
