[Q]Unrooting (the safest way) - LG Optimus Black

I would like to know what is the safest way to unroot because I want to root my phone but I want to have the best chances in case I need to send my phone to warranty.
Can you please show me the best way to do that?
(sorry if this question has been asked before but I needed to be completely sure)
Best regards.

if you flash your original rom via smartflash or kdz update it will be unrooted.
Trolling in the deep

I am no expert, but I think there is no "safest" way. I recommend you know how to unbrick your phone if something goes wrong. Once your phone is rooted and you have a harware failure, there will be no way to unroot it or to flash it, so LG will know it has been rooted. Now, if they will care that you rooted the phone but sent it in because their battery started leaking: I don't know.

If there is a hardware failure, they wont know, that you rooted it. Cause then you probably wont get further, as to the LG screen. They wont be able to boot any further, except he is unable to unbrick it... Otherwise, if you flash the stock ROM and do a factory reset, they will never know

Thank you all for the help you gave me.

[Q] rooting the phone

Hello.
I'm noob with this phone stuff,
I hope you guys can help me.
I have an LG p970. at first it was ok with all the apps that come with it, but now I just want to remove then.
I thinking about root the phone, but
I dont want to lose my warranty, cause my GPS is not working at all.
Is it safe to just root the phone? I mean, there are any risk of brick or something like this?
How can I unroot to send to warranty? Is it easy and safe?
thank you all.
Hey.
- nothing is riskless
- rooting makes losing warranty, but safe
- unrooting is possible but the safest way is to flash a firmware

[Q] Can't update

Hi everyone.
I have an Optimus 2x, and when i updated it to 2.3.4 i could not use superoneclick to root my phone instead i found an answer on how to root it.
I needed to install cwm 5 and after that busybox and so on, and it worked, it was rooted.
Now i have a other problem, i have an update on my phone and when i click on installing it starts to reebot then it comes to cwm screen, there i'm stuck.
I have tryed everything there trying to update it but nothing works.
So now i am wondering if any of you can help me?
Got any idea what i can do to update or what i am doing wrong?
//Szander.
Ok, so now i did a recover so i get back my phone as it was before i installed cwm and tryed to update, it did work fine.
Until the update was done, then it stopped, and nothing i did worked the little android just stand there and looked at me.
So what now, i removed the battery and hoped for the best, now the phone would not bot at all.
After a few tears and a few swear words, i thougt about something, maybe i could use nvflash to get it all back as it was ???
I tryed closed my eyes and after a few minutes i could restart my phone and it loaded as useall, but the update was gone, ofcourse.
So now back to square one again.
Sigh (
Hi Szander,
So just to be completely clear, you're back at a perfectly stock 2.3.4 unrooted ROM and you want to root it, right?
Why not trying to follow cyanogen wiki to root it?

No.
I have cwm, and its still rooted.
What i want is to get rid of cwm so i can update to the latest update wich is v20q.
I have tryed this with recover but its only working on froyo, i belive i read it somewhere.
And when i recovered my phone then the problem really started, but thats fine now.
And as an plus is that now when i run LGMobileupdate tool its saying that i have v20q but in the phone it says that i still have v20I.
Weird.
I have read alittle more and (if i got it right) found out that i might just need to use smartflash on the phone via my computer to get rid of cwm and get a perfectly stocked phone again.
So can you help me please, hoping that you understand my problem.
Yup, as far as I know you are correct. To get your phone back to stock you need to flash a stock ROM using either smartflash or nvflash. I haven't done it so I can't guide you through it personally, but search this forum you should find the relevant threads easily enough.
If you have trouble finding it let me know I'll help you searching.
EDIT: By the way, thanks for Meshuggah, one of the best bands ever I should visit Sweden sometime

Unrooting for warranty.

Hi All,
Before I ask my question, I just wanted to clear up that I've searched the forums (both on the s3 i9300 and i9305 sub forums,) and there's so much info that I got a little more confused and lost my confidence, which is why I'm asking here before I start the procedure.
I've just realized that my power button is starting to wear causing a 'bootloop' when I press it 7 times out of 10, and I have the opportunity to get it fixed under warranty.
Now, I've been running custom software since June 2013 and my phone is an Australian Telstra i9305T, and I have made a backup on the ROM pre-rooted when I installed CWM (although I'm not sure that it may work, as the bootloop have corrupted my SD card, there's a few backups that didn't have the same MD5 and can't be run.)
I wanted to make sure that the steps I unroot and reset counter to 0 for warranty would be:
1) Go to CWM
2) Wipe the cache/memory.(factory reset.)
3) Install the rom I backed up in May 2013
4) Triangle Away to set counter to 0.
5) Use the Unified Android tookit's unroot function.
Does that sound right? Or have I missed any steps.
FYI I had the phone inspected at the Samsung Experience store but the lady had threw a tantrum as she noticed I was running custom software, and pretty much refused to talk to me, (she wasn't even a tech, but I guess got upset on tampering principle,) so I want to make sure when it goes back to the techs it's ok to get fixed.
Any help I can get here would be appreciated.
Thanks in advance folks.

the steps are quite in good order. you dont have the new bootloader with knox i guess.. cause that would be a problem if the knox counter is triggered you cant set it back to 0, there is still no way found to restore knox counter for devices with new bootloader. everyone who has void knox warranty status can forget about sending device to samsung for repair for any reason!
if you havent flashed recently a new 4.3 firmware from sammobile or samsung-updates.com, you probably have the old bootloader which is good.
if you were not rooted when you made the backup in may 2013, then you will automatically be unrooted when restoring backup otherwise you would need to unroot after the backup restore. the backup will restore it to its state exactly how it was in may 2013. after the restore of backup go in odin downloadmode and check what info does it give in the left upper corner about system and binary status, should be both showing official and for the flash counter use triangle away indeed but keep in mind that it does not always restore to 0, sometimes it restores to 1 and thats no good.

Yeah.. I think I rooted the phone before the knox bootloader came out for my phone, although I can't remember as it was a year ago.
So I guess at this stage the steps I'd take here would be:
1) Triangle away to reset counter to 0
2) Go into CWM clear the memory, and put in the unrooted image.
I've now got another question on the steps:
1) Currently using Triangle away, the counter only stays at 1, and every time I boots it shows the red '!' on the top left corner. That's not knox is it? And if it isn't, when I flash the unrooted image, will it get rid of it?
2) How do to revert to the regular stock recovery, as I've installed CWM. Or will the unrooted image handle that... if I recall the steps to rooting is installing custom recovery (CWM in my case) then taking the image with CWM then rooting then installing custom software.....
Again thanks for you help, I hope you can see where I get confused, I love this forums it's got so much help but sometimes it's hard to work out what to filter to make things go smoother.

1. i dont know about the ''red !'' but it seems like you have done something wrong, it shouldnt show something like that..
the backup img might solve it, but dont now for sure
2. to revert back to stock recovery you could do this: flash official firmware with odin OR find a flashable stock recovery .img or .tar md5 file to flash in recovery. easiest way is to flash official firmware, that will restore everything to ''out of the box state'' and for the counter using triangle away (only thing is it restore's it to 1 instead of 0 )
if you ask me how i would make this whole thing ready and steady for sending to samsung, i would do this:
assuming here that i have old bootloader without knox, the steps would be for me in this order:
- put every personal stuff in internal or external sd to my pc temporary
- reset flash counter with triangle away
- go in cwm recovery and wipe everything, i mean really EVERYTHING. after that put phone off and go in downloadmode
- download the official firmware that my phone came with (for me that was android 4.1.2 no KNOX!) when first bought, and flash that with odin. now i have installed official firmware with stock recovery and device status is official and counter reset to 0 or 1
everything restored back to normal except the counter that stays on 1 unfortunately ready to send for repair, but i doubt they will accept it
i do understand your confusion about what to do, as in many threads people telling their own way of handling and taking steps to get things done and that can be very confusing as there are many things one could do. when trying to help people, i always try to provide the most common solutions and most easy one, but no matter how i tell and explain if you are someone who does not know much about android development kind of things, you will have always difficulties. the key for understanding is lots of READING and RESEARCH followed finally by executing what you have learned with proper tools. im just a member for couple of months now but i have followed these forums for many years and im glad i did..

Okay, so now what you're telling me, which is contrary to what I've been reading previous to this is that there is no way to get the phone back to stock for warranty repair as they won't accept it due to the counter being at 1.
(Would this be knox?)
Thanks for your answers tho', I really appreciate them usually my posts get ignored, prolly filed under the "another noob" section.
The thing is I'm not that much of a noob, I just have a hard time trying to put all the info together so I can take the most optimal and risk adverse solution. As for reading and research, xda is a great forum but I can keep reading 8 hours a day for 3 months and keep going because as you said everyone has their own way of doing things and explaining things.
Maybe it's not worth for me to send my phone under warranty if they're going to reject it anywaysy... *sigh*
Despite not being able to help a lot, I would just like to chime in that I have the little red exclamation mark aswell, and I have never installed the Oficcial 4.3 with Knox. So at least its not related to that.
I do have a custom Recovery and I am running a Rooted stock image.
The exclamation mark has not caused me any issues though..

Well it definitely does help, so thanks.
Can I ask if you've sent your phone in for warranty repairs?
I think it has to do with having custom recovery.

Unfortunately not (for you, fortunately for me).. My first i9305 actually had a defective power button which died the day after I got it. I had rooted it already, but was able to roll the original image back on the phone before handing it in. The store swapped it right away for a new one though, so it never turned into a repair case.

[Q] need help with flashing custom roms on xperia z3

my phone isnt rooted but that part i can do alone. the thing is that these processes scare me u know , losing all your data and all that .
can someone please explain to me what will exactly happen and how to flash a rom because my phone isnt compatable with the easy methods such as using clockwork mod
or rom manager. i guess that im gonna need to flash a custom recovery image which i still dont get .
please help
Hi, thank you for using XDA Assist. The first time you flash a Rom can be scary. The best thing you can do is do your homework before flashing and make sure you know how to return to stock in case something goes wrong. The best place to get help is here http://forum.xda-developers.com/z3/help and I'm going to ask a moderator to move your question there
Good luck and happy flashing

Like the other guy said, the first time flashing a rom does sound scary, but mostly anything you do can be reverted and you can get back to stock safetly
as long as you do know how to get back to stock before you flash you should be good
Also you should get to know the key's to get to certain modes I.E: flashmode, fastboot and a hard restart

I have a problem with my phone wanting to update to ZV6

So about 3 months ago when i got my phone i used titanium backup to freeze my system update app, and i then rooted my phone. Today i wake up and my phone tells me it wants to update to ZV6 from ZV5, now i know that if i update my phone being rooted that i risk bricking it. So my question is can i use the ZV5 restore to reset my phone even though if i reboot the phone it might update or how should i go about reseting my phone to stock before updating it, or how should i go about unrooting so that it does not update on me and brick my phone. Any help will be much appreciated
just an update really quick
So going through my system i have found the update.zip file that matches the size the update screen is telling me about, what i wanted to also know is can i just cut the update.zip to my external sd card and that way i have a backup and then when i get home reboot my phone into recovery so that i can restore it to stock, and not risk it updating on me if i dont press the button fast enough. I really need some advice here cause i do not know what i can and can't do with this phone. i used to mess around with an s4 alot before so i have a really good understanding of how to find things in the system, so any advice is good advice. so just let me know thanks a bunch
