[Q] FW .431 upgrade to .587 and keeping root

My phone info:
Model no: LT18i (rooted with CWM installed but with locked boot-loader)
Android v: 4.0.4
Baseband: 2.6.32.9-Perf [email protected] #1
Version: 4.1.B.0.431
I wonder if there's a way to upgrade to the new version .587 without loosing root. From what I understand I will loose root if I update with Pc companion.
In OTA it says PC Companion is required and OTA won't work.
Is there a way to flash some file in CWM or flash-tool even though my bootloader is locked?

http://forum.xda-developers.com/showthread.php?t=1653188

@ExperienceD:
Thanks but I still don't know if my root will be gone or not. The only guide for firmware change was with PC Companion or SEUS what I could find, which I believe removes root. It's so much job to root it again.

do you know why you cant update with OTA?
Its because you have cwm, you must delete cmw recovery and try again with OTA and no if you have rooted 431 and you do the OTA, you dont lose the root
try to install the CWM Recovery and then uninstall maybe that works, but i never tried it

That was indeed real helpful! :good: Now I see, so thanks a lot! But don't think I havn't searched for answers for hours.
Good though that I wrote about having CWM installed, since I almost missed that particular detail.
I'm not quite sure about one thing though; the part with installing and then uninstalling. Since I have CWM installed I figure I'd rather try to uninstall it first then upgrade with OTA and then reinstall it once again. (hope that's what you ment.)
Uninstalling X-parts won't be a problem but I've always thought that X-parts worked similar to "Busy-Box Installer" which can be uninstalled without loosing the "Busy-Box"-installation. But I'll try uninstalling "X-parts" first then look for uninstallation-script in the very CWM-menu if CWM still remains.
I have choosen "Survival-mode" in SuperSU to make the root survive the OTA (didn't think it would "survive" otherwise)

I've realised that the greatest challange is to uninstall CWM. Uninstalling X-parts didn't change a thing unfortunately and there's nothing from within CWM either.
I've almost given up the idea of keeping root, it seems almost impossible! But still I believe there has to be a way to uninstall CWM without wiping everything.

Back up with Titanium Backup or similar and just start from scratch.

I guess there's nothing else to do; I have found that the only known way to get rid of CWM is to install stock recovery and even if I managed to uninstall it all removed system-apps could be an obstacle for OTA to work so I would have to reinstall all systemapps I have removed earlier.

Verizon LG G Pad 8.3 system update

I rooted this tablet last week (just rooted, I left it stock) and this morning I notice there is a system update waiting to be installed. I am reading Lollipop is starting to roll out in Asia somewhere now but I am in the US lol. I thought it wasn't possible to get OTA updates once you root? If I allow this to update will I get unrooted, would it even work?
I foolishly allowed it to update after checking in Supersu to not allow the root to be lost and now I keep booting directly into TWRP lol. How do I wipe this tablet from TWRP so that it is fully stock again (NO ROOT)? I see a factory reset option in TWRP do I need to include all the partitions in the advanced wipe or is just the normal wipe method enough? Or will this not work at all? I already tried to restore the phone using TWRP to my backup and that didn't seem to work.

Simply rooting a device doesn't keep it from TRYing to update via OTA. Rooting can prevent an OTA from succeeding, plus can hard or soft brick if you try to take an OTA, although usually only if you've gone beyond just rooting by installing a custom recovery or changing the contents of any partition besides Data by, fire example, downgrading your bootloader (aboot.img) or modem, running a custom kernel, debloating system apps, etc.
There are at least three variants of the G Pad 8.3. I have the VK810.4G, which do you have?
I know on the VK810.4G, Verizon just released a very, very minor update from LG build #23A to 24A. Still KitKat.
I foolishly allowed it to update after checking in Supersu to not allow the root to be lost and now I keep booting directly into TWRP lol.

There's the main problem, you had a custom recovery installed. OTAs are applied with the stock recovery, that's why it (probably soft) bricked it.
How do I wipe this tablet from TWRP so that it is fully stock again (NO ROOT)?

You might not be able to fix it from TWRP. You could try @autoprime 's fix recovery zip available the same page his flash2 scripts are. You'll have to Google:
autoprime flash2

.
Otherwise, you'll have to restore to 100% stock unrooted and start from scratch. Two methods.
One is using LG's official Mobile Tool, which will download the latest official ROM in KDZ format (takes 20+ minutes to download) and flash it with your tablet in Download mode (probably with the tablet off, hold both up and down volume buttons in and while holding them, turn the tablet on.
I've got to go do something so hopefully someone else will help further or I can get back to you later, dont know when though.
Good luck!

OK now that I am up and running fine the system update message keeps popping up. This time I KNOW not to try and upgrade while rooted. Is there any way I can stop the tablet from constantly giving me the upgrade message? Can I do anything from TWRP to stop this?

Can I uninstall TWRP, keep root , do the update and then reinstall TWRP? If so how? Is there any other way around this issue, any way of not having the tablet continue to ask me to upgrade? Thanks BTW...

Yes, you can do that, but I don't know the steps. Others here do.
Why do you want TWRP? I thought the usual reason was to install custom ROMs (in which case you won't receive any OTA updates). If you just want to root, it's an unnecessary complication (as you have discovered).

Thanks Dean, and yes I do agree with you about it being a complication. I was always under the assumption if I rooted a phone that I needed to also use some sort of recovery god forbid I had an issue with the phone not booting up or something so I could possibly fix the issue, make a backup/install a backup etc. Maybe I will ****can it if someone will tell me how to do so without losing my data or root.

ota update rooted d855

hi, I got ota update today and my g3 is rooted.
I tried updating rooted and it failed, so I checked online to find a solution and I tried to do the "restore upgrade errors" from lg pc suite and it didnt find problems to fix.
so I tried "full unroot" from superSU so now I dont have root and update is failing from phone with 0x1117008 error and doesnt work from pc suite.
how can I do the update? (prefer without backup everything and then wipe...)

Hi you have to go into lg pc suite and wake phone choose reconnect then from mobile tab choose restore upgrade errors....

Remember you will lose root and I have not been able to re-root using the script method after installing the update via PC Suite this morning.
If root is important to you may be worth waiting a bit.

so if I will wait there will be a method to update? All I want is a rooted stock, and a new update has come out. how can I update?

I have a hard time understanding when people want the elevated permissions on their phone, but do not want a means to restore it when they eventually mess it up.
The best method for running a rooted stock is:
Root your device
Unlock your bootloader (if available)
Install a custom recovery
Wipe caches and make a backup
Flash a rooted stock image or a stock-based ROM.
Backup regularly and before any significant change to System.
Enjoy!

I have a stock that I rooted, and there is an update from LG and I want to update but it won't let me because I'm rooted.
the question is: how can I update my phone without backing up and then wipe?

I think I do understand. You are running a rooted stock, want to take an OTA to a new stock, and have it be rooted as well. Correct?

yes, if it can not be rooted at this moment but will be it's fine too

There is never a guarantee that it will be and it may take months. Many times the update is just to fix the exploit that allowed you to root! What I think that you are missing is that you should never accept an OTA if you are looking to run rooted stock. Rooting is something that is typically done ONCE. And once you do, it is advisable to never accept an OTA again.
If you want to run a newer version of stock and have it be rooted, you flash a pre-rooted version via your custom recovery or flash SuperSU via your custom recovery.
Accepting an OTA with a custom recovery is usually disastrous, too.

Flashed faulty [System] from recovery

What happened:
1. Used TWRP to flash an earlier System backup
2. Boots but two system apps force close and phone reboots
3. This goes on indefinitely
4. Can no longer go to either recovery
I'm thinking I should use FlashTool and flash a default System for 14.5.A.0.270 but I can't seem to find any firmware image for it. Does anybody have this/better idea to get me out of the boot loop?
Edit: found the file, will report back.

I wasn't sure from the first post. Does the phone stay on if you don't do anything or does it automatically reboot? I was thinking a good first try might be NUT dual recovery installer, but won't work if phone won't stay on. Check back after your flash attempt - note that you will likely wipe all of your data if flashing with FT.

If you can't boot, you might be able to save data through adb. If you give up on saving data, either Emma or PC Companion can repair phone if you can't get FT to work. Since they're both official Sony programs, they may be easier to get working with Win10.

Which fw did you flash? If it's 5.1, (368 at least, not sure about 216), I've read that Kingroot method is working now.

I got everything back to 270 now. Currently at the optimizing apps part. This all began because I upgraded SD cards and while everything was carried over through a plain copy-paste, my Walkman playlists and favorites didn't make it. I somehow equated the System portion as a possible fix.
Anyway are you on 5.1? Does NFC unlock works? Thanks for pointing me at the right direction.

Use 'installer' option from Z1c downloads on NUT's download page. It's never failed for me. Just watch phone screen and grant 'OK' for adb access and for root. Besides that, if you have unlocked bl, use fastboot or Rashr.

Unrooting help URGENT

Hi I want to unroot my G3 so I can get marshmallow without the fuss and stuff. The thing is flashing a stock lollipop will delete my data, which to me is very important. So I really have no idea of how to backup fully(except rom) other than taking a nandroid. Are there any other ways of unrooting which will undo my mods and stuff, keeping in mind I'm on a stock rom which is rooted, or any simple way to do a backup and restore from a rooted rom to a stock rom.

If I'm not wrong, when you flash the .KDZ it will un-root automatically your device. But just download Titanium Backup and backup all your apps, then install the bumped version of the MM (if you don't have TWRP installed, it is very easy to do it in LL).
I don't remember if Titanium can install all your apps back with theirs respectives datas without root, but you can root the device again if you install the .zip via the custom recovery. You can do it as well if you flash the KDZ, but as I have installed the bumped Marshmallow, I'll let someone else explain it to you.
Of course, if you still want to unroot, as you are in lollipop you probably used Kingroot or some app like that. Just open the app and try to find an option to unroot, most of them have it right when you open it.
Sorry for any typo or broken english, I'm in kind of a hurry

You can always root it again and restore your data using Titanium =P. The recovery is only needed to flash custom roms ou .zip files, like Viper4Android (although you can download the non-official one from Play Store), mods and etc.
I know there are some apps that don't need neither root nor custom recoverys, but I haven't used any of them, so I will let someone with more experience in that area explain it to you.
Just one more thing: I saw that there are ways of downgrading back to lollipop if you flash the official KDZ, but they're a little bit tricky, so I still recommend you to flash the .zip through TWRP (upgrade it to the 2.8.7.1 version if you haven't done it already). If you need more help, or if I wasn't clear enough, just mention or quote me and I'll se if I can help

There are 2 ways to get stock marshmallow running on d855s now:
1. Flash via TWRP 2.8.7.0 by following instructions from here.
2. Downloading KDZ file from here and flashing using LG Flash Tool 2014 or LGUP tool.
I would recommend that you use method 1 since you are rooted. You can use TiBackup to backup your apps+data and after flashing you will still have root and you can restore apps+data using TiBackup.
Also, method 1 is better than method 2 because if you use method 2, you will lock your bootloader and lose root. You MAY not be able to downgrade to Lollipop, and I don't think there's a reliable way to root stock marshmallow just yet.

I think you're misunderstanding me, I'd like to go back to an unrooted version of lollipop and eventually get the official marshmallow update. I don't want to get involved in flashing and stuff, it's just time consuming. So to sum it up - go to unrooted lollipop with all my data(no root mods) and wait for official update.

I don't want to get involved in flashing and stuff, it's just time consuming. So to sum it up - go to unrooted lollipop with all my data(no root mods) and wait for official update.

i think you can use an app called Helium. Then go back to stock using LG Flash Tool 2014 and lollipop kdz

Doesn't helium just do rooted devices? (I had that problem on Xperia devices)
Plus any recommendations for apps to backup everything else?

He wants to unroot the phone and keep all his data, so the only way he could flash the LL kdz and keep his apps would be rooting again and installing the backup using Titanium.
@OP, what root metod did you use? Helium propably will work, but I haven't used it yet. Try opening your SuperSU app and selecting the option to unroot in the settings. Most of 'em have it.

I used http://forum.xda-developers.com/lg-g3/general/guide-root-method-lg-devices-t3129197? to root. I'd use the unroot on my SuperSU but I'm not sure if it'd get me to a state where I can use OTA again. Would I unroot automatically if I updated my phone via a PC?

If you flash the KDZ using the CSE_Flash option, yes, it will unroot the phone. If you just dirty flash it, I don't know, maybe.
If you unroot by using the option in SuperSU, you'll be able to update using OTA, you will only have some issues (aka bootloops) if you have a custom recovery installed. If you have, don't EVER try to install ANY OTA.

I used autorec to get twrp(fairly sure I don't have the latest version of twrp either) would I be fine for ota if I use autorec to go back to stock recovery and then unroot via supersu?

If you manage to install the stock recovery and then unroot, you are good to go!

By repairing, you mean just unroot and install the stock recovery back? I don't think so, the .KDZ file is a full OS. If you flash it you will have your stock recovery and will unroot, but your phone will be factory reseted

Oh so that's a dead end. Anyways for some reason autorec can't restore stock recovery, are there other ways of doing that?

I don't think there is any option besides restoring the stock recovery. I've seen a way of doing in somewhere in a Brazilian forum, but you would have to have a backup of it, which I don't think you do. Anyway, your best chance is to use titanium backup to backup your data (and move your photos and videos to the sd card), restore the system by flashing it using the flash tool, root it again, restore everything using titanium, and unroot. But I highly recommend you to keep your device the way it is, and update just when there is a deodexed Rom or a custom stock Rom available. After you get used to having root and a custom recovery, there is no turning back.
