Question about installing roms/backups - LG V20 Questions & Answers

Hey guys -
This may be a dumb question but i want an answer before i start going nuts flashing. I just installed Tildes rom the other day and i'm enjoying it. i want to try a few others now. Can we do normal backup/recoveries in TWRP now? As in, can i do a full system/nand backup and wipe everything and install CMRemix from scratch, and then if dont like it, i can wipe system/date/everything and just restore my backup?
I remember there being some issues with doing a full wipe when we started because no one had a copy of the original rom. Is that still the case? If so, any tips or advice ?

anyone, buuueelller?

Question, How To Flash Second Time Around???

Hello everyone,
I tried search the answer but only found something in a different phone section and it was not clear.
My question...I have already flashed with the Ice rom and it works fine...when I decide to change roms and flash a NEW one...what are the steps I must do for it to work correctly?
Thanks in advance for any help,
Brian K
If you're staying with the same rom (i.e. upgrading to a newer version of the same rom) - back up, wipe cache/dalvik cache, then flash
If you're changing rom but staying with Sense-based roms - do the same and see if you have any issues. If you do run into issues - wipe data/cache/dalvik cache, reboot.
If you're going from AOSP to Sense or Sense to AOSP - back up, wipe data/cache/dalvik cache, flash.
Its just do the same thing you did the first time. Make sure to do a full wipe and flash

Might be a lil off topic but I think it might be related.....you said 'do the same thing you did the first time'....so i'm guessing first time means the first time i flash a custom rom?? And if so, does that mean for the first time i flash a custom rom should i do a full wipe???
Thanks!

Yes you are correct. The post above mine is way more detailed. You should also do a nandroid backup of the rom you're on now in case you wanna go back.

The best way to move between ROMs is to make a nandroid + Titanium backup. Fully wipe. Flash your new ROM. Carefully re-import settings from Titanium if all seems to be working well. In the event of a failure, roll back to your nandroid copy.
Im really sorry but I still dont understand...I mean I kinda do but dont want to mess up and because of that, I'm trying to have a clear pic in my head.
Example...when you flash for the first time you have to:
flash recovery
wipe data/cach/etc
drop the rom onto the sd card
select the rom from sd card
reboot phone
Do you have to do ALL the same steps again, if you want to try a NEW rom...or no?
If no...what steps do you do differently?
Also...as for the Nandroid backup...do you do this everytime also, or just once?
Again, Im really sorry to be such a newb...but I am trying...I have just about every guide...its just that most guide are not for newbs and alot of times they are outdate. Dont get me wrong I appreciate the guides...I TRULY Do, I just dont want to mess this phone up.
Thanks in advance for any help

Repeat everything as you listed it except for flashing a new recovery (unless moving to/from a Froyo/Gingerbread; as recovery differs between Froyo and GB). I usually only make nandroid backups once I have found a ROM that I like and have it working well. It's a system restore! Then if I want to tinker with the "shiny new ROM" that just came out I can load it up and play with it. If it doesn't work well or at all, just roll back to your faithful fully working nandroid copy you made.

Actually switching between Froyo and GB has been made even easier by the new ClockWorkMod Recovery... TrueBlue's method works amazingly... Find it here http://forum.xda-developers.com/showthread.php?t=944681... Flash it like you would a ROM via CWM... His zip also INCLUDES the STOCK RECOVERY so if you ever want to recalibrate the battery you can do so by going into Rom Manager and selecting 2.5.1.4 as your recovery, when done just switch back by selecting 3.0.0.5 and that will load up 3.0.0.6..
To answer OP's Question...
Step 1) NANDroid backup (Backup and Restore > Backup > press trackball)
Step 2) wipe data/cache/dalvik (I always do each of them twice for safe measures); Like someone here already said, if upgrading to a new version of THE SAME ROM BUT ITS BEEN UPDATED, just wipe CACHE AND DALVIK. Otherwise, wipe all 3.
Step 3) Install zip from sdcard > choose zip from sdcard > select the ROM you want to install.
P.S. FYI I WOULD DO THIS FIRST!!!!! For flashing TrueBlue's 3.0.0.6 to be able to flash both froyo and gingerbread roms without changing the recovery each time (which is a pain in the ass btw) FOLLOW STEP 3 EXACTLY. The only difference is you will choose GlacierRecovery_to_RomManager.zip instead of whatever Rom you want. Reboot, go into RomManager, scroll to the bottom and select All ClockWorkMod Recoveries, choose 3.0.0.5 and it should say successfully flashed. Reboot into recovery and make sure at the bottom it says CWM 3.0.0.6. If it does, congrats, if not, reboot and reflash it, and continue to do this until you see CWM 3.0.0.6 at the bottom of the recovery screen.
PM me if you can't get it to work and want some more help with anything!
Hello,
I want to say it again, that the people in the Android forums are so much more helpful then back when I had a iphone and needed help. The people over in the iphone forums would sometomes help, but most of all, they would be rude.
Android forum techs are the BEST!
As for the Nandroid backup...this part also is a bit confusing, cause a few guides/videos show them doing the nandroid after they do the 3 wipes. However, I thought it made sense to do it first like you said.
Last night at around 4am I flashed CM7 with no problem and it is truly amazing. I am started to make sense just a little bit of all this but right now...I still cant wrap my head around the whole flashing recovery process.
Please understand I.m not just asking for answers, I am also reading as much as possible...I am making an effort.
Thanks so much everyone,
Brian K
No problem. If you have any questions I'd be glad to answer them for you or direct you in the direction for your answer. Just pm me like I said.
Just continue to read read read.. That's why I did and this is the first phone I've rooted or done anything with and I've become knowledgeable with some of the easier concepts and I'm trying to learn more complicated concepts as I go along.. Everyone had to start somewhere, and most of us here on xda realize this which is why we are so happy to help as long as these questions aren't asked and answered 4000 times.
P.S. Where ever you read/watched to wipe before NANDroiding I would advise to not go back to that because that is COMPLETELY the wrong thing to do!!

No prob Brian I know I wasn't as detailed as other ppl who helped but if you have any questions just pm me.

I know I keep saying this but so far everyone here is sooo freakn helpful. Im shocked cause when I had a iphone and did the whole jailbreak thing...the people over there where very rude.
dont worry dnguyen1988...u were nice enough to help out and I promise to take you up on the offer for help
Amac1222...just to be clear...your saying to do a Nandroid backup before wiping ANYTHING...yes?
Thanks again for everything,
Brian
Yes, even when updating your rom, you can always move the nandroid off your sd to an external hd. Or you can delete them as you move up updates, (i.e. Build 41 to 42 to 43 delete 41 once you know 42 is good to backup to if needed). When I flash kernels I tend to not nandroid each time although I should. As a super noob I would and I used to until you are comfortable.
The basic thing is you always want something to fall back on in case you get stick in a boot loop or stuck on the mytouch screen.

Advice for full wipe and clean install

Hi all, i am sure that somewhere there is a post which can help me, but i have searched not only here but in other forums and did not fined exactly what i was looking for.
Here is the topic: i want to wipe the entire data on my nexus 7, yes all , was playing with different roms and now i want ot settle with only one. And want to do it absolutely clean. I found some scripts (small apps) that can do it for me, but they wipe even the recovery. Now i dont want to wipe that part, i have latest TWRP and there is a option inside to wipe data , no media, no sdcard .. all gone. As we have an emulated SDcard, the Rom i want to install will be gone too. How , and is this really possible, to wipe all and send a Rom.zip file afterwards somewhere so i can install it.
I see that WugFresh's Tool-kit have an option to install a zip from the PC to the device , but will this work after a full wipe of the device ? I really don't want to clear recovery and install it again , just wipe data and install clean.
Will be very happy to hear a solution or a confirmation that it will be ok to do it, and how is the easiest way
Really Thanks in advance !

[Q] Different backups, superusers, and flashing kernels

Hi all,
I have learned a lot about Android customization in the last week since my Nexus 4 finally arrived at my door, and I have become reasonably comfortable with the processes of flashing ROMs/kernels, and backing up my phone to make sure I have something stable to return to if something happens to go wrong. However, I am still dealing with a few points of confusion that I was hoping someone could clarify for me:
1. I have CWM installed on my phone and I can use it to backup/restore images of my phone for safety. However, I have heard about other methods like Nandroid, Carbon/Helium, and Titanium Backup while browsing the forums, and have tried them only to become confused as to how they are different from using CWM backup. Could someone please explain this to me and clarify which is the best for keeping a backup of my phone stored on my computer?
2. I have noticed that when I "wipe date/factory reset" in CWM, not everything on my phone is wiped. There are still plenty of files left over from previous ROM installs when I browse my phone with Android File Transfer, and obviously the .zip files you need to flash new ROM's/kernels are left too. What exactly is deleted when do a CWM factory reset?
3. Is it necessary to wipe everything when installing a custom kernel? I have CyanogenMod 10.2 installed because it is quick and relatively bloat-free, but allows for enough customization that I can make the my phone feel the way I want it to. I want to give Matr1x/Hells-core a try, but I am tired of factory reseting everything when install a new kernel. Can I get away with just wiping Cache/Dalvik and flashing the new kernels? If not, what is the best way to avoid losing app data between ROM and kernel flashes?
4. What is the difference between the default Android superuser, CWM superuser, and SuperSU? They all seem like the same thing and it makes me nervous installing different ones.
Any information you guys can offer would be great. Thank you so much for your time !

A backup in CWM is the same as a nandroid backup. It basically take a "snapshot" of your ROM and restore it exactly as it was when backing up.
Titanium Backup is an app that backup your apps and app's data. It's recommend you only restore user's apps and data. Let Google restore any system app's data.
2. I have noticed that when I "wipe date/factory reset" in CWM, not everything on my phone is wiped. There are still plenty of files left over from previous ROM installs when I browse my phone with Android File Transfer, and obviously the .zip files you need to flash new ROM's/kernels are left too. What exactly is deleted when do a CWM factory reset?
Wiping data/factory reset only wipe the data. Wiping system will wipe your ROM (system partition) Of course you don't want to wipe all the files such as the ROM you're going to flash.
There's an option to format internal sd, that will wipe EVERYTHING so unless you know how to ADB push files or sideload a ROM, DO NOT touch that.
3. Is it necessary to wipe everything when installing a custom kernel? I have CyanogenMod 10.2 installed because it is quick and relatively bloat-free, but allows for enough customization that I can make the my phone feel the way I want it to. I want to give Matr1x/Hells-core a try, but I am tired of factory reseting everything when install a new kernel. Can I get away with just wiping Cache/Dalvik and flashing the new kernels? If not, what is the best way to avoid losing app data between ROM and kernel flashes?
No, just flash kernel. Some recommend wipe cache and dalvik cache after kernel flash before reboot.
4. What is the difference between the default Android superuser, CWM superuser, and SuperSU? They all seem like the same thing and it makes me nervous installing different ones.
Different app that does the same thing. Usually go with what is recommend by the ROM's dev. I ususally just leave what's included with the ROM.
Any information you guys can offer would be great. Thank you so much for your time !

[Q&Help]Updating roms.

I have a question? I'm using PA rom the last version.So when they have a new update I need to Full Wipe&Flash&Cache my device for install the update ? Or just install it and done.
and other question, someone can give me a full tutorial for full wipe&cache&flash when I want to install a new rom?
I will really appreciate if someone will help me. Thanks
(Sorry for my english..)​
Honestly those choices are your own. If you want to start fresh by all means and if you want to flash over current setup its also your choice. Just note the latter would mean no complain or bug reports should be made.
OP will have all your information on how to flash a rom its a simple step, TWRP has the option for wiping and it will wipe data cache and davlik all in one shot.

ROM decision

Hi guys,
I'm looking to install one one of these two ROM's:
http://forum.xda-developers.com/galaxy-s4/i9506-develop/truongtan-s6-edge-rom-t3207809
or
http://forum.xda-developers.com/galaxy-s4/i9506-develop/rom-t3014552
Has anyone tried both ROMs long enough to give a good verdict on functionality, stability, performance and battery life etc.?
If no one has tried both, then I am willing to trial both, however I have never actually switch a ROM on my phones before. I have always found an outstanding ROM and stuck with it. What would be the correct and safest steps to switch between these two ROM's?
Thanks guys!
1. Install the first ROM and have it completely set up as you like it, with all your apps.
2. Make a nandroid backup of that ROM.
3. Install the second ROM and set it up as you like it.
4. Make a nandroid backup of that ROM.
Now you can switch back and forth at will.
Wow! You can tell how long it long it has been since I last got into the modding! I completely forgot about that! Cheers man! When installing each of these ROMs or changing to another nandroid backup would you recommend that I do every possible wipe or just stick with data and cache wipes?
Just the cache wipe. Data will be restored when you restore the nandroid. Of course, there's nothing preventing you from doing all the wipes if you want. Case in point, usually when I flip-flop between Albe95's S6 port and the non-Touchwiz ROMs I'll wipe everything first. I don't have to, but it doesn't hurt either.
