[Q] HELP Needed to recover TWRP backup

Hi,
I have a GSM Galaxy Nexus, I bought it in November 2013. Here is a sequence of events I performed on my galaxy nexus:
1) Used Galaxy Nexus Toolkit V9.1.0 to install Android 4.1.2 (Build JZO54K)
2) Rooted and unlocked my phone (through a friend)
3) Installed Cyanogenmod 10.0 nightly in start of December using TWRP 2.2.2.0.
4) When 4.2.1 ROMs came out tried installing it using TWRP old version but then got to know updated version 2.3.* can directly install 4.1.2 ROM without using Galaxy Nexus Toolkit V10.0 so went for it. Meanwhile I used TWRP backup feature to save my Cyanogenmod and I recovered it later on when I didnt like 4.2.1 ROM.
5) Today, I decided to try 10.1 cyanogenmod a try. Downloaded yesterday's nightly and though it would be good to wipe cache/delvik cache and without even wondering what I am doing wiped internal storage and factory settings as well. After this I installed new nightly but when I restarted my phone the cyanogenmod circle just kept on moving for more than 5 minutes but the ROM didnt load. I knew I was in trouble.
6) I tried installing a rom but couldnt after which I had to used Galaxy Nexus Toolkit V9.1.0 to Flash Google Factory Stock ROM of 4.1.2.
7) I saved my TWRP rom recovery folder to the internal memory (tried putting them in TWRP folder or just main folder but it won't show up when I press recover in TWRP. I tried TWRP 2.2.2.0, 2.3.2.0 and even 2.4.1.0 but none would load the restoring files.
8) I treid the above TWRPs to install the new nightly as well but again after installation, it would just keep circling and the ROM wont load.
PLEASE HELP ME ......
Currently I have updated tp 4.2.2 Factory ROM as I got it as an update while I was on 4.1.2 factory rom.
Can you tell me how to bring the phone back to normal? I think the synchronization of root+unlock+TWRP has been broken.
Thanks.

There is no "synchronization" to break.
Follow one of the stickies in this section on how to properly root your device with adb and fastboot then follow the directions.
Then if possible move the contents of the old TWRP folder into the new one.
Toolkits are seriously the worst thing to happen to XDA. Nobody bothers to learn anything if there's a tool to do it for them then they wind up helpless if something goes wrong.

Can you let me know a useful like for that? I am thinking of installing Galaxy_Nexus_ToolKit_v10.1.0.exe and take a fresh start.

I just explained what you should do. If you're going to insist on using a toolkit then I can't help you any further.

[Q] What will happen when I update to android L?

I am running stock. No ROM but I am rooted, and I use Franco kernel and xposed framework, what will happen to those mods? Im afraid of brick, should I uninstall all of those including root first before updating to L... When it comes out? Please I need answers, I had soft brick before and I don't want it again.

You should only have to wipe, yes you will loose the mods, but they will probably be updated. You will just have to wait a month or 2.

Wipe everything right? Like factory reset or twrp? Will I have to reinstall root/Franco?

Franco will need to create a new kernel, the old one won't work after a version update. Xposed will work if you manually flash the update; if you want ota you'll need to disable it first and revert to stock recovery.

You'd have to try really hard to brick a Nexus device. What's so scary about a soft brick? Learn how to use fastboot and adb and there's absolutely nothing to be scared of.

Actually I was going from cwm to twrp and I didn't know the wipe buttons would get rid our my OS altogether..? my dumb mistake.
But I was saved by nexus 7 toolkit

Yea don't worry about bricking. You will be able to restore thru nexus toolkit as long as your bootloader is unlocked. I wiped the os off my nexus 4 as well.

I just took the plunge and xposed isn't working nor is my showbox.
Android L is really cool and I can live without xposed, but showbox not working is a big hit. I just got it all setup too. Works good. No real problems.
I flashed back to stock and wiped, then upped to L
How do you flash back? Can I just flash a custom 4.4.4 ROM or do I need flash stock?

Just like you would any other ROM in recovery or fastboot. If you want stock, flash stock. If you want a custom ROM, flash a custom ROM.

Multiple choices. If you made a backup/nandroid before flashing L you should be able to restore your backup without any issues, For one thing the bootloader didn't change. You can fastboot flash the system and boot images after extracting them from the factory image then wipe cache and dalvik. Flash the whole factory image either with or without modifying the flash_all.bat (open the flash_all.bat in notepad and remove the -w which will prevent the storage from being wiped). Or... flash a custom or stock ROM. Piece of cake!

Good to know. I'm trying to hang on but we'll see

Updating Nexus 7 (2013) while rooted?

I have a Nexus 7 (2013) running Kit Kat (4.4.4) and recently got the the OTA update to 5.0.1, but haven't installed it yet. I rooted it using the WugFresh Nexus Root Toolkit sometime some the last OTA update.
So how do I update to Lollipop? Do I need to unroot with the toolkit first? Will I need to backup my apps first and restore after the update?
Also, for some unknown reason, I no longer have the OTA update although I was notified that it had been downloaded. Odd! Guess I'll have to manually download it and side load it.
Thanks in advance...

In order to run the stock OTA you need to put your system back to stock. That means stock recovery, remove ALL modifications to the system partition (root, ad blocks, etc...) then you can run it. If that sounds like too much work - just back up and flash the factory image then restore.

I was rooted with the Wugfresh toolkit. I downloaded the 5.0 (and later 5.0.1) factory image from Motorola and unpacked it. I edited the flash-all.bat batch file (right click, Edit -or- right click, Open With, select notepad/wordpad) and removed the -w flag from the end of the file. It's not the very end, but very close. Just delete the -w and any excess spaces and save the file. The -w flag is what tells it to do a wipe of all data, removing it will prevent that. Put your Nexus into bootloader mode and double click the batch file.
Once it finishes flashing, it will boot up and say "optimizing apps" or "Android is updating" or something like that. Mine took about 15 minutes. After that, run the Chainfire Auto Root (CFAR) script to get root access back, and you're back in business.
Note: flashing Factory Images and running CFAR require an unlocked bootloader. CFAR will unlock the bootloader AUTOMATICALLY as part of the script. This WILL RESULT IN A LOSS OF DATA. If you are already unlocked, you're fine, as long as you remove the -w flag from the batch file.
Also, you do not need to go from 4.4.4 to 5.0 to 5.0.1, you can jump straight from 4.4.4 to 5.0.1.

At least a few of us have used that with no issues. I was running stock rooted 4.4.4 with TWRP, so I updated my bootloader, rebooted into recovery, wiped cache and Dalvik (probably not necessary before flashing), flashed the ROM, wiped cache and Dalvik again, and rebooted, and it's working great with no loss of data.

^I am going to do this, after reading similar reports of success.
However, to OP I want to stress that it is important that you update your bootloader before flashing the ROM. The patch is attached to the linked post.

While I am definitely tech savvy, I am not that comfortable with the WugFresh toolkit. For example, I just updated it to v1.9.9 and connected my device. While I know I previously unlocked the boot loader and rooted my device, the toolkit itself does NOT tell me if my device is unlocked or rooted.
Is there a tutorial somewhere describing how to update to Lollipop with the WugFresh toolkit? Thanks to @fury683 for the comment about editing the batch file. But I don't know what that means with respect to the toolkit user interface, that is what buttons are clicked in what order. I need a step by step list of instructions before starting.
@OrBy, by flash the stock image, do you mean the 4.4.4 image or the new 5.0.1 image? And how do I flash the image? WugFresh toolkit?
I used the WugFresh toolkit a few months ago, but have forgotten the steps I took. Should have written it down. I'll try to stick with the WugFresh toolkit.
Thanks for all the comments

Factory images and Wugfresh are not used together. Wugfresh is a collection of things while factory images return the device to 100% factory stock out of the box. If you modify the batch file as detailed above, no user data/apps are removed, just the system, recovery, etc partitions.
Factory images are a one click method that has a very similar end result as Wugfresh does to return to stock. I would go with factory images as it is the easiest and most straight forward method. Run batch, confirm, wait about 1-2 minutes, done.

Well if your hung up on running the OTA then the 4.4.4 but if I were you I would just flash the 5.0.1 and skip the who OTA.

I managed to update to 5.0.1 without wiping the device using WugFresh. I went to the WugFresh site, read the FAQ, and found how to update without wiping clean. Turns out there is an option to disable wipe without editing the batch file. I was able to do the while procedure leaving the device unlocked.
I did have an unexpected issue. I had to reinstall in the USB drivers on my PC before I could re-root it. WugFresh made this part easy too, though I'm surprised a reinstall was even required. Once that was done, USB connection was restored and I could complete the rooting process.
I always stress out whenever updating Android in any way. The rules are different with each device and OS version.
One change I've noticed I'd that my Nexus 7 brightness I'd dimmer and I have to turn to setting higher. Hope the update is worth the trouble.

Follow up: after all the work upgrading to 5.0.1, I decided I didn't like the new version. I did the upgrade without a clean wipe. But I did the downgrade with a clean wipe.
The WugFresh toolkit is quite capable utility. I couldn't imagine doing it the hard way with the adb command line interface. At least know how to recover and rebuild my system should the need ever occur in the future. And Titanium Backup is indispensable too.
I found Lollipop to be a battery hog. Perhaps I'll try it again when some of the issues are worked out. There is no compelling reason change from Kit Kat at this time, IMHO.

This is NOT true. I upgraded while rooted and it went fine. Just beware of xposed and other tools that mess up with /system and thus the upgrade scripts.

While I was able to update from KK (4.4.4) to LP (5.0.1) without wiping the data, it didn't work out for me. The battery life was terrible. It drained at least twice as fast compared to before the update. I was trying to avoid the pain of a clean install. But in the end, it wasn't worth with it.
I ended up going back to KK, and then to LP again but with a clean install. When installing LP the second time, I wiped the data and let Google reinstall all of the apps. There were a small number of apps, that I later restored the data from Titanium Backup, for example games with previous scores.
This made a huge difference in battery life. Plus the look and feel of many apps changed to the new Material design.
I'm not entirely sure I like the look of LP. I'd prefer LP under the hood, but the look of KK. Oh well!
Bottom line: don't do OTA updates with a major new release.

How to update from 5.0 to 5.0.1 with TWRP?

I am on 100% stock 5.0, just with TWRP and rooted.
I already got my Nexus 5 updated to 5.0.1 with a stock rom but from looking around here I can't find any stock flashable roms, they're all modded ones requiring a wipe which I don't want.
I honestly feel bad posting something like this and maybe I'm missing something right in front of my face but in tons of searching I haven't found anything to simply update stock without completely wiping my device or installing a custom rom. Neither of which I want to do.
Thanks in advance.

Umm, yeah. If it was a snake, it would have bit you. LOL
Anyway, here's the link to Scrolser's stock, rooted 5.0.1 rom you need: http://forum.xda-developers.com/nex.../rom-factory-stock-rooted-rom-lrx22c-t2960745 . I used Wugfresh's NRT 1.9.9 to update the bootloader listed in Scrolser's post, then dirty flashed (no wipe) the rom using TWRP. I wiped Dalvik and Cache just because... Worked great for me and no loss of data!

[Q] Bought used rooted LG G3, how to tell if it has custom recovery?

Hello all,
I recently bought a LG G3 used as a Christmas present to myself. I've just set it up and noticed that SU installed fine from my playstore account, and after verifying I see that it's already rooted. Is there some way to tell if it's also been set up with a custom recovery as well? I have pending system updates and would like to go ahead and install, but not if it's going to soft brick the phone.
Or is there no way to safely install system updates with just root, and I need to completely wipe to stock anyway?

Download an app from Play store that let's you reboot in recovery mode like Quick Boot (Reboot) and check for yourself.
As for the updates you must be completely stock and unrooted if you want to install OTA Official system updates.

Download 4 way reboot app from the playstore and then use it to reboot into recovery. If it goes into TWRP you've got twrp

You might also install "root checker". Then you'll know for sure if its rooted or not.

Thanks everyone for the quick knowledge. Downloaded root checker which confirmed I'm rooted, and downloaded 4 way boot which shows I have stock recovery.
Since I need to be completely stock to install OTA's, what's the recommended way to go back to stock? I would prefer not to have to do a complete wipe, but it’s not the end of the world if it’s needed.

Download your desired firmware and flash with LG Flash Tools 2014.
Follow the guide in this post : http://forum.xda-developers.com/showthread.php?t=2785089
It has options for normal flash without losing data and a CSE Flash for a fresh format. Although I strongly recommend doing the full wipe CSE Flash Option and a factory reset from stock recovery after flash so you won't have any problems - best experience. Good Luck.
