[Q] Root Flash then Revert Without a PC? - Nexus 5 Q&A, Help & Troubleshooting

Just wanted to know if its possible to root (towel root) flash custom recovery and custom roms and then if I decide to later revert totally back to stock unrooted nexus without a PC. Ive attempted to read up on this but I'm a little confused that ill need to use SDK and ADB which i can't have access to at the moment or have the skills to use.
I've seen apps on google play to unlock boot loader once towel rooted but I'm just unsure if i can revert totally back to an unrooted nexus 5 with original recovery, without a pc as I'm using an iMac and having really unreliability with it :/
Id greatly appreciate any help :good:

You may need a computer to return to stock but otherwise you shouldn't need a pc

The nexus devices are the easiest devices to get back to stock because Google supplies the stock images

There are a couple different options.
I'm not sure if flashify requires a unlocked bootloader. Root, flash custom recovery with flashify, make a backup. When you are done either restore backup or if stock already use flashify to flash stock recovery, delete root apps, unroot via supersu.
Boot unlocker I have heard will work to lock and unlock boot loader but I'm not sure about resetting the tamper flag.
Using fastboot and adb is always going to be the surest and safest way to root etc. Unless you are going to be submitting your phone for RMA there should be no reason to unroot. You can always flash a stock rooted ROM and just leave it.

Steps are;
-Download boot unlocker fr on play
-Download flashify from play (just in case)
-Download vomers stock ROM (number 6 in resources section in the link in my signature)
-Download stock recovery (number 7 in resources section in the link in my signature)
Firstly, flash the recovery zip via your current recovery and reboot
Then, reset The tamper flag and lock the boot loader
Finally, open SuperSU and use the full indoor option to remove Root
Good as new.

Adb push

I know how to use adb and I'm not too inexperienced with it. Is there a way that I could push files to the system partition without having root on the device? I'm on stock ROM and I do not want to unlock the boot loader or root it, I just need to push a file to the system partition.
Sent from my Nexus 5 using XDA Premium 4 mobile app
I am pretty sure you can only push files to the SD card without root. Rooting/ unlocking doesn't hurt. Try helium for a backup.
I know it doesn't hurt, I just came back to the stock ROM after using my own compiled ROM. I just didn't want to mod it except that one file, thanks though

Not without unlocking your bootloader.

Okay, if I decide to unlock, I can use adb to backup my data partition before the unlock and then restore it after I unlock right?

Hmmm. Not sure if you can access /data without root via adb. Helium backs everything up so maybe it can. Try it. Im never unrooted enough to know

Here's a good guide to use when performing an adb backup. No you do not need root.

Stock recovery?

If I root (towel root) install custom recovery then unroot and factory reset will I have stock recovery back?
Sent from my Nexus 5 using XDA Free mobile app
Sent from my Nexus 5 using XDA Free mobile app
no, factory resets only wipe your user data, they dont magically reinstall software. but you will after you.. a. flash the factory img, or b. flash the stock recovery via fastboot.
all info and guides are linked in my signature. Lots of reading but lots to learn.

You could extract the recovery.img from the stock rom and flash it

Help with in call issue

Im having an issue with my calling. When I go to make a phone call to anyone the screen is completely black and I can not access my dialer or anything else while I'm on the phone but if I turn on my Bluetooth lg tones and make a phone call the screen will turn on and let me navagate threw my phone and I don't know how to fix this issue I was running android l from the Google website. Then I went to slim ROM weekly with Franco kernel and posted about my issue was told to flash factory image so I did and still broken. So I decided to completely unroot to 4.4.2 and lock my bootloader and take the 4.4.4 ota to see if that would fix the issue and it is still broken I'm curious if anyone has heard of this problem and has a solution to the fix? I also tried to just flash the 4.4.4 kernel and that didn't work either. Thank you for any help in advance

Most likely a hardware issue with the location sensor. If you're still under warranty I'd consider using it.
Edit, if you have a case on take that off first, it could be interfering with the sensor

Download the 4.4.4 firmware and flash that in fastboot. Google nexus 5 factory image. Extract it and double click on the flash-all.bat. If you don't have fastboot, Google 15 second adb install xda. That'll set it up

Installing with fastboot didn't work, or it did, but same problem? An important clarification.
I flashed a stock factory image with fastboot and it didn't work then I unrooted the phone to stock 4.4.2 took the update to 4.4.4 then tried and it was still broken then I rooted and tried again and its still broken

If it's the same after a fresh stock install, then it's likely hardware. Tho honestly, I've never heard of this particular issue.
Thanks for your help on this that's just whatbi don't understand because it was all fine until I rand dev preview of android l let's hope the 5.0 ota fixes this issue if not then o well
Sent from my Nexus 5 using XDA Free mobile app
Wait. You need to solve your fastboot issue and flash stock. What you've done won't change anything. You need a clean install .
---------- Post added at 08:20 PM ---------- Previous post was at 08:18 PM ----------
Ota"s are not clean installs. Figure out the fastboot issue and flash 4.4.4.

Proper upgrade path

Sorry for the noobish question that I should know, but it's been a while since I've used an HD.
I picked up a used HD on 9.18.94. Can I simply sideload 183.46.10 and run the bootloader unlock? My first goal is the bootloader then I can flash root and unlock the radios so my wife can use it on ATT

Yep, just upgrade straight to .10, unlock, root, and you'll be good.
