Can I revert back to stock without a computer?

Can I revert back to stock without a computer (just like it was when I first bought it, locked bootloader and all)? I don't have access to my computer at this time and want to revert back to factory stock all from my phone. Is this possible? Any links to assist with this?
Thanks.

to get to a stock rom yes it's possible. you will not be able to lock the bootloader as far as i know.

I see. So I would need a computer to lock the bootloader?

as far as i know you need a computer to lock the bootloader, yes

as far as i know, yes

A couple of people have posted similar threads and no, there is no way to lock the bootloader without a computer.
One user who was trying to send his phone in with a broken USB port actually tore his phone down and ghetto rigged his USB port to work...lol.

Heh... I'm in a very similar situation. Could you actually send me a link to post? I'd really like to lock the bootloader before I sent the phone in. Desperation is seeping in!

Unrooting Nexus Without USB

Hi Guys!
Now that i got that error with the USB Plug not working I need to unroot my phone and send it back to samsung (I already figured that relocking the bootloader isnt possible but i guess ill let it come to that).
All the tutorials i found where using fastbood and not the recovery, right now I'm on a rooted JB Rom, after ich had several Custom Roms installed (i.e. CM9)
Is there any way to get back to stock just using the recovery and not having to use the USB port?
Thanks in Advance

It's possible to relock the bootloader if you have root.
There is a guide on how to go back to complete stock + locked bootloader w/o USB cable.
Maybe i should drill myself a few times with it, let me dig out the link.:good:

I need to try everything with my Black screen of death in order to repair it
So, I have seen this thread: http://forum.xda-developers.com/showthread.php?t=1923943
but in order to follow it I need to unlock bootloader, and with the BSOD I cant see anything even in fastboot mode, so how can I unlock it?
Please help :S!!

Why don't you just take the warranty repair while you still can?

I cant sent to warranty because I open it to change the battery 2 month ago, everything works fine but now...
OK, I have unlocked already the bootloader thanks kskendsup , but now, I cant flash a ROM because it isnt in the list of adb devices, because I cant enable (turn on) the USB Debuggin option as I cant see anything :S

The most dumbest thing ever, you should have send it for warranty .....like they know what happend with the battery, everything was 100% stock and they had to give warranty !!! My humble opinion ......
You are screwed !

[Q] Some Rooting Questions About The Nexus 7 Flo

Hi,
Sorry for the silly questions. I just want to quickly check some things about the Nexus 7 Flo.
QUESTION 1: I'm constantly scared of bricking my device when rooting it. If I brick it when rooting, will ASUS repair it? If not, is there a tool I can use to unbrick?
QUESTION 2: If I use the All-In-One toolkit, how likely is a soft brick/hard brick? Can I un-everything (unroot + lock + install stock ROM + stock recovery) using the All-In-One toolkit if I need to?
QUESTION 3: If something happens with the hardware (e.g. port broken, screen cracked) and I am everything'ed (root + unlock + ROM installed + custom recovery), will ASUS repair it?
QUESTION 4: Can we get ParanoidAndroid 3+ for Nexus 7 Flo yet?
Thank you, and sorry for the noob questions!

As far as I know, you don't have to unlock the bootloader to root. If you do, and need a repair, see question 2.

I would say unlikely to soft brick, and very unlikely to hard brick. And yes, you should be able to undo everything with a toolkit / fastboot commands.

If the USB port breaks you might have a problem, since you need USB connection to issue fastboot commands, which are used to restore the device to locked, stock state. If the firmware is altered and/or the bootloader is unlocked, the warranty is void.

@ameinild, will ASUS still repair it for me (but for a fee), or will they refuse to repair it at all? I don't understand warranties

Honestly I have no idea. I'm not too sure about how vendor repairs work either.
But as long as you don't erase or corrupt your bootloader (which would be an amazingly stupid thing to do) or smash your USB port, you should be good.

@ameinild, I have another question: Will ASUS know my device has been previously rooted or unlocked? Is there a triangle or something? Thanks!

I'm pretty sure they can't know that in any way - I don't believe Nexus devices have a counter...

Not entirely true. Ordered mine from B&H, rooted, etc., and woke the next morning with a hard brick. Even restoring through fastboot did not work. So I wiped system, recovery, and boot, relocked the bootloader, and sent the device back for a refund. Just received the refund today without question. Simply told the customer service dude the device wouldn't boot when I received it. I know, a little dishonest, but I followed all instructions to a T, I believe it was a hardware issue anyway, though I only overclocked to 1800 or so.

But you still managed to relock your bootloader, meaning fastboot worked which is the important thing.

Did I brick my device? :(

I was on 8.1 with Flash Kernel installed using images...I wanted to get back to stock...so unchecked OEM Unlocking in Developer Options, went to bootloader and locked bootloader using fastoboot flashing lock..and now I am getting "Can't find valid operating system. The device will not start". I can't unlock the bootloader now as I unchecked OEM unlocking in Developer Options and can't flash factory images also as it says Flashing is not allowed in Lock State, Did I brick the device?
Update: I have returned my device to Google and they processed a replacement

i am just curious, how were planning on flashing a rom with locked bootloader?

Yea, I think you may have turned it into a fancy paperweight. Been there, done that. You should have waited to uncheck OEM unlocking until after you locked the bootloader, which wiped your phone. About the only thing I can suggest is to try and run Deuces script to see if you can rescue your device. Best of luck to you.

Sorry for your loss, but you indeed have a fancy paperweight.
However I wonder if there isnt the QCom USB mode or something like that that exist on older devices, where you can access the phone partitions at a lower level and then restore whatever partitions is broken.

Yeah at that point... Not sure what is Google saying about that. Maybe RMA it ?
Saying something like that should work.

since your phone is now essentially a brick, you can try just about anything without worry of bricking your phone.

You cannot flash full images, but you can still flash OTAs... download the full OTA instead, and install (sideload) it from the stock recovery. Be sure to select the SAME build number you were on to begin with- eg. If you were on 8.1, use the 8.1 OTA. There will be a mode there for "Apply update from ADB". You put the phone into "sideload mode" and then send the OTA to the phone via adb. This will work regardless whether you have usb debugging enabled or not. Follow the directions given on the included link.

I didn't. They are still paperweights sitting in a drawer!

I got the same message yesterday after doing... God knows what. I can't even remember what went wrong.
My first thought was to flash a factory image. But it didn't helped at first. Probably, because i was trying to flash another factory image and not the one that came as stock on my phone.
So if you don't remember, which image it was, try all of them Hopefully, you'll get your phone booted again.

My first reaction was, is this april fools day? Is this an xda style joke? unchecked oem unlock?

Meh...you know how it is bro....**it happens!

Call google and just tell them your device wont boot all of a sudden; they will probably ask you to factory restore in the recovery, say the phone wont get past the google image. They will RMA that boy for you. You totally bricked. For future reference if you unlock the bootloader, dont waste your time trying to lock it again. Should have just fastboot flashed a factory image in the bootloader and called it a day. Having a unlocked bootloader doesn't effect you in anyway negatively.

Why is this Google's problem? This guy is at fault. Google shouldn't have to pay for it.
This is part of the reason these phones are so expensive.

Well I never said it was the moral thing to do haha; but this guys best bet is to call Google and see if they will RMA it. They RMA'ed my Nexus 6p after the Android 7 twrp brick; and I told them my pone wouldn't boot anymore; they asked me to go to recovery and factory restore, I told them I couldn't boot into recovery and they RMA'ed it. It was my fault for the brick but they didn't care.

I told them I had an unlocked boot-loader and installed twrp. I had to send them back my old phone and they put a $500 hold on my account, once they received the device and determined the issue was real, they released the hold on my account. In that period of time they could have determined "Oh he bricked the device with twrp" lets charge him $500 for a new one, but they didn't. I mean whats wrong with calling Google and seeing if they will RMA it; sure the OP made a bad mistake but you have not because you ask not.
