[L5] How do I completely unroot and reset to factory? - Optimus L3, L5, L7 Q&A, Help & Troubleshooting

Hey, I'm pretty lost here.
I'm not much of a genius when it comes to android, but I tried to root my L5 anyway because I'm an idiot lol...Yes I did read countless websites and I did understand the risks involved etc whatever. Anyway, today I tried flashing cyanogenmod 10 on the L5 and pretty much ****ed up. Now I think i've lost root access, I can't uninstall superSU and pretty much my phone is ****ed up i guess. So the question is: how do I completely unroot and restore to factory settings?
I want to do this because I wanna give rooting and flashing a second chance. Is it completely necessary to restore to factory or is there a simpler way to just get it back to normal?
Thank you very much and sorry for the nooby/annoying question.
P.S. I did some searches on the forums and there's some similar questions but none that solve my issue so pls don't hate XD

To completely get it back to factory, try this..

is it safe to restore rooted gingerblur atrix?

i just got my atrix which happened top be rooted and aparently has gingerblur which i dont like to much
can i do a master restore and not worry about it getting bricked?
sorry if this is a newb question but this is my first android device
Short answer is Yes it is safe.
you can flash a sbf file and be back to stock, there is a lot of info on this board on how to flash an sbf so you should be able to find it pretty easily.
So you wont brick your phone if you follow the directions but you will lose root and sideloading, if you want those you can look into GingerBreak and GladEnable, also on this board to re do those after flashing back to stock
check out this thread for the sbf file you will need

Root Question

Okay so I just have a few questions about rooting my phone before I do it, since I saw the root here that works for the most recent OTA update.
1) If someone happens with my phone (either bricking it from rooting or something inconsequential) will they not replace my phone due to it being rooted?
2) If they won't replace it due to being rooted (if it wasn't bricking), is there an easy way to unroot the phone?
3) I can't tell from the instructions, but I'm pretty sure some others have said that it might require you to restore factory settings, does this one require that?
4) The thread says that it is now impossible to unlock the bootloader, does this also mean that you can't use a custom ROM? How exactly do you add a ROM?
Sorry for all the questions, I've never rooted an android device before, and I don't have the time or energy to go running around Google/forums trying to find these answers.
Thanks in advance!
EDIT: yes I know i've already asked 2 of these questions, but I'm a stupid poop who needs validation.

first, rooting your voids the warranty, so technically, they (either VZW or Motorola) are not obligated to replace it. that being said, you can always play dumb and say that you accepted some OTA install, and now the phone won't boot up. usually, VZW will try to restore the phone, and if not, they'll replace it - no worries.
2.) I believe there is an unroot method, but I have not explored this. try doing a search on this forum for "unroot razr m"
3.) restore factory settings could unroot - check the threads
4.) you can still install a custom ROM, but you'll need to install Safestrap first. however, the custom ROMs available for SS are out-dated, and I don't think that any devs will be providing any going forward. however, I would not be too discouraged by this, as the phone is very solid stock. so rooting is the key to remove the bloatware to help increase battery life, increase performance, and reduce excess data usage.
hope this helps.

[Q] Removing root. Unable to upgrade

Hello folks. Unsure weather or not i post this in the correct place. So i rooted my SM-N9005 the other day just because well i"had" to. Ofcourse the next day the 4.4 update got released and i couldn't upgrade since my by now unfriendly phone told me i had tampered with it. I tried to restore it without really knowing what the hell i did and feeling a bit stupid for not getting it. I managed to remove root but it still says it's tampered with. Reckon i triggered the flash counter somehow. I could really use your help removing root and get my little phone back to "original" shape. Talk to me like a 3 year old since i apparently couldn't figure it out on my own. Cheers!
(And yes I have been reading so much about this my head spins now. I tried different ways to recover but i cant get it to work. I intentionally left out all the different apps i used here from the forum since that will probably confuse you guys aswell.)
how did you root?
download the kitkat firmware from sammobile then flash it using odin (so you don't need to upgrade via ota) then re-root

Ok, it started when i tried to root it by following an online gtuide. However it didnt work so I tried another one and "semi-bricked" it. Using odin. I tried readiing up on it as much as i could but the more i read the more different ways i found. Long story short, i rooted it. It worked fine. But removing root didnt seem to do the trick. I would just like to return it to stock without ruining anything. And be able to upgrade OTA if possible.I love fiddling with these things but since i pay so much for this damn phone I rather not do anything more that can destroy warranty etc. As i understood it rooting it wouldnt leave a trace and should be easy to undo. Now I understand that wasnt the case. I know I am the one to blame but would love if anyone could just try to explain what to do in a simple step by step way. If you need any info on what i did I can try to explain but i ended up with like 12 different webpages open with different solutions and to be honest I am not sure I can explain everything i tried...

How to fully unroot + recover device into factory default

I've rooted with King Root. Since I have got troubles with GPS and need to send phone for repair, I need to completely unroot with no trace that phone was rooted. Do you know hot to do it...? I've found that after unroot via King root RW is still mentioned while booting, so it's not clean unroot... Please explain if you can step by step.
Thank you very much.

Can you just do a factory reset from the recovery menu? Before I bought mine on Ebay I asked the seller about rooting and what if it bricks, he just said I can send it back within a month with no questions asked more or less.

Didn't try yet, in the meantime rather asking. Now did Nandroid backup and trying to find out if I can flash it without root in COS recovery or need to root again, install Nadroid backup and restore vie this app.
Also in Nandroid backup is missing script for Lenovo ZUk Z1 and no chance to find it, so I will cross fingers that it will not cause additional problem during recovering from backup...

Tried factory reset and full wipe and still not updatable, OTA update ends with same log "system was RW mounted" so it seems it's irreversible if you root. Very bad news, so you can't then apply warranty.
Do you have anybody advice how to reset into facotry default without any trace device was rooted..?????
You could try this toolkit, but you will need stock rom. http://forum.xda-developers.com/zuk-z1/development/win-zuk-z1-toolkit-0-1-alpha-t3235964
So it seems, it's not possible to make safe root and unroot on ZUk Z1 device as far as I know. Maybe somehow very difficult. That's not great news indeed. It's my first phone ever not possible root / unroot safely. And it's giving me feeling that Z1 despite it's great device in terms of hardware is not good choice. Also quite surprised how far away from well tuned OS is current release. I can't understand, why just CM didn't develop OS with possible root right or didn't incorporate full device backup. Honestly I don't care so much and probably neither other users about root, if natively in OS is complete backup / recovery. And... If I can do root without possibility go back (reclaiming warranty or not functional OTA update), then it makes me think, if really Z1 via CM is good choice or not. Despite really nice HW and materials... Pitty

No you should have read how to do it before you touched the phone. XDA is not a spoon feeding centre. It's for people who want to help themselves. If you had done the reading and had an issue with getting a part of the process to work, yes, but to blindly rush in and want it sorted out because of your own +++++ I must sound like a #### but you learn then act. Everyone has 4 posts and a screwed up phone wanting help. Errr there is a link between the two.
1.Flash a clean COS image via Twrp
2.Flash a clean COS recovery via twrp or adb sideload
3.Lock the bootloader

Couple of rooting clarifications needed

I've had my S5 for two and a half years now without ever resetting or anything. My phone has become crazy slow lately and I'm looking to do a complete wipe on it and seeing as the warranty is no more, I figured I'd give rooting a go. I have some questions about that though:
1. Is factory resetting a phone like re-installing windows for example? Clear it of all junk and we're back to square one?
2. Is rooting the phone going to automatically factory reset it? If not, do I factory reset -> root or first root then reset?
3. Once rooted, I understand some apps like Android Pay may stop working, is that correct?
4. Is rooting invertible? If I decide I need some of the apps that no longer work, can I go back to normal state?
5. After a root I can install a different version of Android, right? Would that make it possible for me to get closer to native Android and be able to remove all the excessive irritating stuff added by Samsung?
Thanks for you help.

I'll answer your questions in order:
1. Yes
2. No root doesn't factory reset the phone, and you don't need to factory reset before rooting. if you need help rooting I'll help you
3. Yes that's correct
4. Yes you can unroot and go back to a regular unrooted s5
5. Yes, these are called custom ROMs. I can help you pick a custom rom if you'd like
Thanks for the answers. You say factory reset is not needed, but isn't installing a new rom gonna wipe what's currently present? If not, do you think it would be enough to speed things up or a reset would be in order?
I am somewhat busy the upcoming couple of days but I think I'd try to root next weekend or so, so I'd love the help with choosing a rom beforehand yes. Is there a list of the available ones and which one is stable, etc?

Installing a suitable ROM will definitely speed up your phone, it always did for me. And yes, this will delete everything currently present on your device. So be sure to have backupped stuff you want to keep.
