Restoring to stock ROM (N1 ATT) - Nexus One Q&A, Help & Troubleshooting

I have been testing the N1 for a few days, and just making sure there aren't any hardware issues before I void the warranty (possibly) through unlocking the bootloader and flashing a ROM. I would like to know if it is possible to revert to a factory settings ROM with exactly the "out of the box" settings and OS.
Backup: Unlock, install a RA-nexus recovery, save current ROM to SD, save settings with a backup app.
Restore: Start RA-nexus, recover ROM from SD, do factory settings wipe.
Is this correct?

Currently you can't relock the bootloader, you can revert everything apart from this. It does void your warranty but apparently HTC have been decent about fixing rooted N1s with hardware defects anyhow.

As @nDrg said, you can't relock the bootloader, but you can restore the phone completely to the stock ROM... download the EPE54B stock ROM, rename it to PASSIMG.zip, copy it to the SD card, enter bootloader mode. The phone will find the zip and ask you if you want to apply the update... this will restore everything to the stock EPE54B ROM

Didn't work for me, please help...
Hello,
I tried to place the above listed file on my SD (tried the one from the link on your sig, and one from another source) and could not get it to recognize the file from bootloader, nor could I flash it from zip (via recovery).
I have been searching for a way to revert to stock ROM for days now (and I have been researching) and I can't seem to find a way that I can get to work. (I am running both cyanogenmod 5.06, and modaco's sense - switch back and forth with the RA revovery screen). I can't connect reliably to wifi on either, and want the option to go back to stock.
I'm very much new to Android (and the Nexus) thus I'm probably just missing some things that are obvious to more advanced users.
I was hoping that you might be willing to post a step by step guide to reverting to stock for newbies? (Explain each step, eg. I barely know what fastboot is). Or, do you know of a guide that you could point me (and others I'm sure) to?
One might ask why I rooted and modded my device when I did not understand enough of what I was undertaking to reverse the process. One would be absolutely correct in such a question! That being said, if anyone is willing to help, it would be much appreciated.
Thanks so much,
Randy

Just curious why you'd want to go back to stock?

@prettyboy85712:
I do love both cyanogenmod and modaco's sense rom, but I haven't been able to connect via wifi on either for quite awhile (though normal network connection works fine). To be more specific, if I have been able to connect via wifi without the sim card in the phone, but not with it inserted.
As well, it seems like a good idea to be able to revert to stock if I did need to (stock updates, etc.) and I'd like to try wifi with stock, to see if it's the phone or the ROM. (My fault for not figuring out how to do this before I modded )
Thanks so much,
Randy

if u want to go completely back where u still receive ota (minus the locked bootloader that u can't change that its unlocked) u can download the signed secure nexus 1 Rom from modaco and then flash the boot,system,and recovery.img though fast boot go to nexus one forum and search rolling back to stock Rom it gives detailed instructions on how to do it I did it to make sure it works and was simple it is and u even get ota updates from Google hope this helps if u need any help just send me a pm good luck let us know how it goes

[Q] rooting nexus one

hey guys i just got my nexus one 2.3.3
im confused what 2 do first
root, unlock bootloader
what 2 do first?
and i preffer to do all these things WITHOUT adb, bcoz adb never works with me
You can't unlock bootloader without ADB (or actually without fastboot, but if you can't get ADB to work, then you probably won't be able to get fastboot to work - since they work the same way).
My suggestion is - do nothing. At least until you'll be able to follow one of the guides and get ADB and fastboot to work. Then you can decide yourself, whether you want the bootloader unlocked or not, and how will rooting benefit you.
what are the benefits of unlocked bootloader?
i just wanted it to get it rooted and flash CM7 on it
It has been discussed a lot, please search to get A LOT of answers.
In a very short version, the benefits are:
Safe radio updates (using fastboot)
Ability to flash whatever you want whenever you want - which is, permanent ability to have root access, regardless of the currently used OS.
but is it possible to flash CM7 rom without unlocking bootloader?
whenever i boot my nexus one, there is this little lock icon on the bottem that is "unlocked"
is my bootloader unlocked?

If there's lock icon at the bottom of boot splash screen, it means the bootloader is already unlocked. Is it used one?
yes its used, i guess that guy alrdy unlocked it for me
another problem
i have serius wifi issue, its different from the other wifi problem
if i connect to my wifi its authenticating, then disabled
i dont even go to sleep its just says disabled after authenticating, i tried reconecctint but same things happens again...
i installed wifi fixer but that doesnt work either
also, my 3g drops after 4 sec and i cant get it to work afterwards
Flash a new ROM, wipe your data, and try.
Repeat.
If the problems will still persist - they're in HW and you can't do anything about them.
i tried factory reset but didnt work...
This is exactly the reason why I suggest not touching your phone.
You either don't understand what exactly I'm guiding you to do, or don't understand the difference between various maintenance/repair operations. Flashing a new ROM and wiping user data from custom recovery ISN'T the same as doing "factory reset" from within already-installed ROM. Flashing 2 ROMs with different base (for example, lightly modified stock and CM7, or CM7 and MIUI, etc) introduces enough difference on the SW size to (almost) make sure that any problem which persists in both new ROMs, is coming from HW.
In any case, I suggest either waiting for someone with much more patience than myself (which isn't hard - patience isn't one of my strengths) to explain you some basics that you're not willing to learn yourself by reading, reading and some more reading, or to give your phone to someone who knows what he's doing.
dude....
i rooted and flashed many roms b4, this isnt my first android phone
i just got confused data wipe with factory reset....
Ok well now I need to know if you have a custom recovery, if so then just 5X wipe plus 3X system wipe and flash a new ROM, if not then do you have root access if not I'll walk you through the process.
shiyou
You are in good hands with Dude
Couple points:
Don't use Clockwork Mod 3.+ as recovery--which seems to be your next step--get a lower version
I prefer Amon_Ra 2.2.1 for my recovery
BACKUP phone (NANDROID) as soon as you get the recovery
Look thru Cyanogen thread from OP page and last few dozen pages
Cyanogen flashes a little differnet with having to flash gapps separate and flashing Dark Tremor's a2sd after each Nightly flash
i know how 2 root,flash,wipe, nandroid and all
i did it many times b4
i think i wont use nightly builds, but a stable? or RC?
which should i take?
How about cm7.1 RC1 that is the latest version of cyanogen mod.

why not clockwork recovery 3? the cyanogenmod rc1 states that i need that?
should i use gingerbeak? im on 2.2.3 and install the recovery afterwards?
ok i rooted it with gingerbreak and flashed clockworkmod recovery on it
after that i went into recovery and couldnt find nandroid backup so i rebooted again
i tried to make a backup via rom manager and it ended up with a "!" icon
i tried to go into recovery again and again i got the "!" icon
I don't know anything about Gingerbreak
But, on CWMod 3.+, it has been unstable for a lot of people--I don't recommend it
If you have Rom Manager--flash something like 2.5.1.4??
Still recommend Amon_Ra
I am not sure, but if you get the exclamation, you may not be rooted
If you are experienced at flashing, I would as another poster suggested--get to know your phone and study hard info from the Rom threads you want to try before trying.
What color was recovery--did it say ClockWork
I don't think you will see the name Nandroid in Clockwork--just Clockwork backups
A couple more suggestions, if you want
Back up sd card regularly--you will lose it on occasion--if you need to reformat it, use sdformatter outside of phone
Partition sdcard with zero swap
Wipe all (data/caches) multiple times before flashing new rom, including System

[Q] Nexus One stock GRJ22 (rooted) with apps2ext?

I'm currently running with a rooted version of the latest stock firmware on my N1, and I love the stability and all, except Google's apps2sd implementation is really dumb.
With only a dozen or so apps I am already getting low storage errors.
I've tried flashing in DT's apps2sd but unfortunately it didn't seem to work at all. Are there any other options for me to get apps2ext support without switching to a custom rom?
Try Link2sd in the Market.
It may be better, it may not, but it's worth a try...
Hey SmallWalrus,
I am running stock 2.3.4 unrooted Nexus one. (yes, that is GRJ22)
I have never rooted a phone. Can you please point me somewhere which shows how to unlock and root the N1 with my specs. My phone is pretty old. I am only rooting it because this is a spare one and I now have moved to SGS2.
PS: using a mac and Linux machine. If not then please show me a windows one. i'll try dual booting my macbook pro.

Have you unlocked your bootloader? That was how I did it though, there is no other way to root 2.3.4 without doing this at the moment.
That is what i want to know. How do i do that safely?
Well there is a way to safely root your phone without unlocking the bootloader, I did those steps recently and they worked fine for me.
1. You need to downgrade your phone to Froyo. Get the FRG83 image from here: http://forum.xda-developers.com/wiki/index.php?title=Nexus_One/Roms
Rename it to PASSIMG.zip and copy it to the root folder of your SD Card. Boot your phone into the bootloader and flash the image. This will wipe your device, so be sure to make a backup of your data and apps first.
2. Use SuperOneClick to root your phone. http://forum.xda-developers.com/showthread.php?t=803682
3. Now you need to flash a custom recovery. I used the Clockworkmod one, because flashing it is very simple: install the Rom Manager app from the market, it has an option to flash the recovery.
4. Now you are set to flash custom ROMs, either through Rom Manager or the Recovery. You should however do a Nandroid Backup first, in case anything goes wrong in flashing the ROM. Boot into Recovery and you should see a menu item saying Backup or something.
It's really not a big deal as it sounds, I can't guarantee that this will work for you. You should know what you are doing and if you feel unsafe about any of these steps, make sure to search the forums or the web about it, before you execute it.

Sorry, I didn't see your question until now
Actually, it IS very easy to do this, you can find the instructions here:
http://android.modaco.com/topic/299078-how-to-unlock-the-bootloader-on-your-nexus-one/
It does have some warranty implications though, but since I am already using an import set I don't care. According to some, HTC usually shuts one eye and fix your phone's hardware failures even if it has an unlocked bootloader, but YMMV.

[Q] Help with root and custom ROM.

Hello guys,
I've been looking around hier for a while, and I spotted a Custom ROM that I'd like to try, it's this one: http://forum.xda-developers.com/showthread.php?t=1424260
I've never rooted my phone before so I don't have experience with it.
I found a couple of threads that can help me but, I don't know in wich order I have to follow them.
First of all, I'd like to make a complete back-up of my current ROM, so in case something goes wrong, I can restore it. How do I do this? I read something about ClockWorkMod and a nandroid back-up, can somebody clear this out?
I have an unrooted HTC Incredible S with S-ON. So first, I think that I have to get S-OFF? I found a tutorial with the Revolutionary tool, but it doesn't support my HBoot, so I think that's not an option?
So then, I found this tutorial: http://forum.xda-developers.com/showthread.php?t=1337105
The tutorial is easy to follow, but can I create a full back-up before I start the tutorial?
And to get S-OFF, do I need a rooted device?
I hope somebody can help me. If you need more information, just ask.
Here is some information about my device:
- Android 2.3.5
- HTC Sense 3.0
- S-ON
- Not rooted
- HBoot 2.00.0000
- No SIM-lock
If more information is needed, please ask.
Unfortunately having your current h-boot the method available to you to root and install custom ROMs does not let you back up your phone prior to flashing. As the method used is flashing a new ROM that allows root access to your phone. Prior H-boots (1.13.0000) allowed you to root your phone without flashing a custom ROM thus unlocking boot loader to be flashed CWM as a custom recovery and allowing you to create a nandroid backup of your current state before flashing a new rom. However[/] the process you are going to need to complete might contain a back-up function included in the flashing process, I don't know for sure as I flashed from 1.13.0000, but it doesn't really matter as your going to have to complete the process anyways. I say just go for it and follow the instructions to the "T". If you follow everything properly and take your time you shouldn't encounter any problems.
In the tutorial I posted, step 10 is
10. Using volume up/down and power to select, go down to Backup/Restore. Select it, then hit Backup. ClockWorkMod will backup your stock ROM in case there are any dramas and you want to go back to it.

Will this create a complete back-up? So when I restore it, will everything be back the way it is right now?

Exactly. Stay safe.
So if I just follow that tutorial, I will have a Custom ROM with root? And do I still have to get S-OFF?
You don't need to go S-OFF to flash a custom rom. There is actually no need whatsoever to go S-OFF, unless you want to go and flashing other radios. But the lastest sense 3.0 and android 2.3.5 update included the lastest radio, so keep S-ON. Better for warranty.
First go to htcdev.com and follow the instructions to unlock bootloader. BE AWARE THAT THIS WILL WIPE YOUR PHONE TO FACTORY DEFAULTS for security reasons, sdcard remains untouched.
After bootloader unlocked you can flash the clockwork recovery (you're still S-ON). Once you flashed that you can go into recovery with volumebutton down and power on. Take a backup with clockwork (=nandroid = full image of the phone in its current state) of your original rom and start flashing custom ones.
They're is probably a time where you gonna think you bricked your phone, I have. But I always got through it by searching the forum. Always, in any circomstance, manually push the boot.img of the associated rom from a PC to your phone. So never flash a ROM from your sdcard if you don't have a PC in hand. Otherwise it will probably not boot or get hardware not working (not broken in anyway, just not properly loaded).
Before changing roms, I always do the ARHD wipe script. Just to be sure every trace of the previous rom is gone. There are multiple partitions on your phone (system, data, boot). It wipes all of them to start clean.
The ROMs you are going to flash are rooted by default.
So now, of you go and be a ICS beta tester
Thanks fot the explenation.
But, because I can't root my phone because it's HBoot 2.00.0000; I can't make a back-up of it? Not even with Titanium Back-up.
Is there any way I can back-up my app's? So I don't lose all the saved data in the app's?

As far as I know the answer is "no".
You need clockwork for a nandroidbackup, you need bootloader unlocked for clockwork, unlocking bootloader wipes your phone.
I accidently wipe mine with the unlocking of the bootloader. It seems harder than it is to start over. Just link contacts and calendar with gmail, backup sms on sdcard in messaging. That's all you need. Starting over is good to get the crappy apps gone
Hmm, okay, then I'll have to do it without making a back-up.
And is there an easy way to switch between ROM's? Without using a computer.

It is very easy to change roms. They are stored in zip-format on your sdcard which you can browse to with clockwork. Also the nandroidbackups are stored on your sdcard and can also be chosen with clockwork.
Experience tells me that you still need to flash the boot.img of the rom manually after you flashed the rom (something to do with clockwork not able to write in boot partition while in recovery-mode, you have to be in fastboot-mode). Flashing the boot.img litterly takes 2 secs to upload, done, and reboot.
So it is no big deal to swich:
- boot in recovery
- browse to the desired rom/backup
- start and wait 5 mins
- boot in fastboot
- connect to pc and flash boot.img
- wait 2 secs and reboot
Do not flash when you need the phone and there is no pc around. If it goes wrong, you need your usb pc to fix things.
I heard something about Rommanager, can I use this and what does it do excactly?

ROM Manager is an app that works with ClockworkMod recovery to keep it up to date and allows you to make and manage CWM nandroid backups and manage partitions on your SD card. The paid version also allows you to download custom ROMs and flash them.
It requires root access in order to run.
But it's not a necessary application?

[SOLVED] updating unlocked\rooted\s-off htc one to 4.3

Hi everyone,
im a newbie android user, have my device for barely 2 weeks.
i have a couple of questions on my mind, questions i tried googeling answers to for days now,
as i didnt find clear cut answers, im asking for your help.
i know i can flash a the stock 4.3 rom using custom recovery (i use TWRP) but that will result in wiping my data.
im interested in updating my AT&T HTC One to 4.3 without losing my data.
note that i currently have an unlocked bootloader, root (supersu) and im S-OFF (used Revone)
i already figured that i need to unroot my device and re-lock the bootloader in order to receive the OTA update properly.
my questions are as follows:
1) do i need to flash back to stock recovery in order to update or is unrooting and relocking bootloader good enough?
2) since im S-OFF, updating to 4.3 will update my hboot but will keep me S-OFF? or will it turn it on? or maybe it wont even update and stay on 1.44?
3) after i update to 4.3, re-unlocking my bootloader will once again wipe all data?
4) after updating to 4.3, in order to re-root my device i follow the same procedure i did on 4.1.2?
5) since im not using an AT&T sim card, i had to flash some wifi files in order to bypass carrier check and turn on wifi tethering, i imagine im gonna have to do that again on 4.3, will the same files work or will i need to wait for a new hack\workaround to come out? (i used: http://forum.xda-developers.com/showthread.php?t=2285047)
i have a few more questions that i cant recall right now, too much google digging for info got me confused.
will add them if\when i remember.
Thanks in Advance.
You don't need to relock bootloader or remove root, you do need stock recovery and stock ROM. Hboot will be updated, S-Off will remain. Your data will not be lost. Follow same procedure for root.

Thank you for the quick reply.
a few followup questions if u dont mind.
1) where do i get the stock recovery files?
2) how can i identify the correct ROM associated with htc one 4.3? i know i need to use Cingular as my HTC is an AT&T one, but the roms versions are listed by AT&T firmware.
3) do i flash stock recovery and then do a regular OTA update?

Just a quick question: why do you want to go through all that hassle to receive the OTA? Since you're S-Off you're able to flash unsigned firmware. The only reason I can think of using OTA, is if someone is S-On and therefore cannot update firmware; an unlocked bootloader allows you to flash ROM, kernel, and radio, but not firmware. with S-Off you CAN do that.
One piece of advice, in either case, DO NOT GO S-ON EVER!
Or did I misunderstand you?

There are files in the firmware.zip that wipe the phone, removing those files means it won't wipe. Often boot.img and recovery.img are also removed from the firmware you download from here.

What do you mean by data? your internal storage/sdcard with pictures, music, etc. or your apps?
When flashing a new ROM with different base (eg 4.2.2 to 4.3) a wipe is recommended (that would wipe your apps and their data, not sdcard), but you could use Titanium Backup, Helium, etc. to back those up and restore.
You can do a dirty flash, which would not wipe your apps, but could lead to some potential problems with some apps; in which case you would need to reflash with wipe.
Anyhow, be careful with going back to stock first, because when you flash the stock recovery, it will/could wipe your phone completely including sdcard. Happened to me while I was testing a few things, and just flashing stock recovery and accessing it, wiped my apps and sdcard.
Hit us with some more details, what ROM (etc.) are you on now, and where do you want to go.
This is where I am now (attached pics)
I would simply like to upgrade my HTC to 4.3
I would like to do that without the hassle of wiping my phone and restoring apps data.
But if it's necessary I'm willing to backup and restore the apps data.
As u said, my SD CARD contents will no be deleted? ie photos, music etc.
From what u guys told me, I gather that doing an OTA is not as simple as I thought.
Can u please tell me the easiest way to upgrade?
or even better, what my options are?
2nd pic attached, for some reason it let me attach only 1 pic.

In my humble opinion, you should do a full back up of everything (nandroid, apps+data AND sdcard) and copy all that to your PC.
Whichever way you proceed, you're going to be moving from Android 4.1.2 to 4.2.2+, that will change the file structure on your phone: in 4.1.2 sdcard points to /data/media/ but as of 4.2.2+ it now points to /data/media/0/ (this is due to multiuser support in 4.2.2+).
For some, whether OTA or flashing a custom ROM, three things have happened:
1- the sdcard (pictures, music, etc) files were moved correctly to /data/media/0
2- the files were duplicated in /data/media AND /data/media/0, so they had to manually delete the duplicates (root enabled file explorer needed)
3- the files were not moved at all, and had to be manually moved from /data/media/ to /data/media/0/ (root enabled file explorer needed)
Note: that once you're on 4.2.2+ /data/media/ will no longer show up when you connect to your PC, only /data/media/0, hence why you need a root enabled file explorer to access /data/media/
If it was me (and I like a clean phone ), I would flash the new custom ROM in recovery, then while still in recovery format the /data/media/ (/sdcard/), boot up and let the ROM setup the sdcard as brand new.
And then setup the device from scratch. Copying all pictures, music, etc. back using your PC.
For backup/restore of USER apps & data, I would take a look at these:
* Titanium Backup
* Helium
* SMS Backup & Restore
* Call Log Backup & Restore
and possibly the built in HTC Backup.
Titanium can back up the data of system apps, but it's not recommended to restore these especially between the large gap from 4.1.2 to 4.3; usually you could restore WiFi, Bluetooth and a few more settings, but there have been reports that due to the changes in all of these, the restore of system data could/was causing problems.
Finally, if you want to upgrade your firmware, use vomer's guide here: http://forum.xda-developers.com/showthread.php?t=2365506. The firmwares there have boot.img (so no need to reflash RIM), recovery.img (so no need to reflash custom recovery) removed as well as the files that would wipe the sdcard. So you can flash the firmware without any negative effects.
Of course you could just do all the backups, and try dirty flashing (without wipe), and see how that works out for you. In case you run into problems (eg apps force closing, missing widgets, bad Wifi, bluetooth, or mobile data), you can then reflash with full wipe.
This is all my personal opinion, so don't know if anybody disagrees with my thoughts.
EDIT: if you use CWM recovery, you should also take a look at this after upgrading: http://forum.xda-developers.com/showthread.php?t=1991657
Hit the thanks button if I helped
Sounds good. Tyvm!!!
I'd like a clean phone as well.
So lets me know if I get it straight:
1) flash Rom in recovery (after backing up media and/or non-system apps)
2) wiping SD CARD clean
3) flash firmware in recovery
4) flash radio in recovery
Did I get it right?
Again thanks on advance

Yes pretty much, the most important part is the backup, I would do:
1- a nandroid backup in recovery (just in case you want to come back to that)
2- perform a Titanium Backup/Helium of everything (you don't need to restore system apps/data, but it's good to have them anyway)
3- perform HTC Backup (I do it, but have never restored from it yet)
4- copy everything from the sdcard (which would include above) to PC
firmware (modified versions by vomer) and/or radio can be flashed at any time without any risk of loosing apps or sdcard.
You should be good to go.
PS: In case you format sdcard and /system/ and find yourself without an OS (by accident), you will have to use 1 of 3 methods to get the ROM you want to flash on the phone:
1- adb sideload
2- adb push
3- OTG cable
Which firmware and radio version I need?
Whats the modification done in vomer's firmwares? Just removed files to prevent data wipe?

Firmware and radio are pretty much up to you; especially radio, where newer doesn't always mean better, it's very user specific, but you can flash them so easily in recovery back and forth. (I have them on my phone all the time and experiment depending on my location)
Also, just remember once you go to 2.x firmware or above the touchscreen drivers will no longer work with a 4.1.2 ROM, but then again why would you want to go back
The files in vomer's firmware that are removed are:
1- stock kernel (boot.img), otherwise you'd have to reflash ROM.zip after updating firmware
2- stock recovery (recovery.img), otherwise you'd have to reflash custom recovery after updating firmware
3- I don't recall, but some firmware package had a files in them that would wipe the sdcard (but haven't seen those for a while)
Firmware and radios are all available in vomer's guide: http://forum.xda-developers.com/showthread.php?t=2365506

you'll have to do it manually, I'm using CWM, so I have to go to "mounts and storage" and then "format /data and /data/media (/sdcard)"
hmm, on that thought after formatting and booting up your ROM, check if all the apps are there, some get installed to /data/app, and I wonder if the above would delete those.
Wouldn't be a big deal, you would just copy the ROM back to your sdcard using your PC and reflash it. (Maybe do that anyway)
At least you know you'll have a clean sdcard without any possibility of duplicates or other files you no longer need (eg temporary files from some apps)
Alright, I've done it!!!
Upgraded to 4.3 stock Rom, which came with 3.17 firmware.
(used: http://forum.xda-developers.com/showthread.php?t=2476204)
Flashed AT&T OTA radio.
Even found a new tether hack for 4.3 that will allow me to activate tethering while not on AT&T network
Thanks a lot for all the help,
Much appreciated.
One more question tho if that's ok,
Are there any downsides to upgrading my firmware from 3.17 to the latest 3.62?

Congratz.
As for firmware, I can't think of any downsides to upgrading it. Since you're S-Off you can always downgrade it back to 3.17 if you find any incompatibilities, though I dont think there will be any.
Alright ty.
The current firmware I have is 3.17.502...
Which came with the Rom.zip I flashed
I only found 3.17.402... on xda
Would u happen to know where I could get 3.17.502... ??
As I wouldn't want any problems or incompatibilities with the 402 one.
Also should I bother updating my hboot (if it's even possible)??
Thanks again.

Are you sure the ROM.ZIP contained firmware?? Usually, ROM.ZIP only contains the ROM and firmware is separate; also because the two have different flashing methods:
1- custom ROM is flashed using custom recovery
2- firmware is flashed in fastboot RUU mode
can you post a "fastboot getvar all" (remove IMEI and s/n before posting) to see the details.

Help a newbie; LG Optimus L90; learning to flash

Current situation: pretty much complete newbie. I broke my factory OS after rooting it, I think I deleted something Settings needs, so anytime it needs to access settings I get "Unfortunately, Settings has stopped." I factory reset it hoping that would help, but now after loading it gets stuck on a cycling white screen reporting that error (I think it's trying to set up the phone.) The error message prevents me from doing the touch-four-screen-corners trick I've read about and bypass set up. So, stuck on phone setup errors as near as I can tell.
I do have my user apps backed up with TiBu, but couldn't get the recovery zip from TiBu to work. I downloaded CWM but didn't figure it out yet. Also unfortunately I can't get the USB drivers to work (the LGE Android MTP Device won't install), so I think my only way of getting files to my phone now is using the microSD cards.
I'd love some help! I think my factory OS is FUBAR, so I'm not trying to fix that, instead I'd rather just get a cool ROM loaded so I can continue learning with a working device with said cool ROM. I don't fully understand terms that I know I need to like "bootloader" or what CWM / TWRP actually does or how to use them (I need to make a custom recovery ROM?). Or where to get a cool ROM or which to pick, some step by step basics on from some experienced users would be fantastic! Thank you so much!
So you were on stock, rooted, backed up and then messed the ROM? Flash stock ROM again using LG Flash tool (there is a thread in the main section), it should not wipe your data but you'll lose root. Hard to fix if you're not sure about the problem and have no easy access to files. Just make sure you flash the correct version for your model (D405, D410hn, etc), preferably the same version you have now so you won't need a factory reset after flashing...

Thank you, this put me in the right direction. I ended up discovering that even though the " LGE Android MTP Device won't install," the flashing process worked with this program via USB anyway. I'm going to lick my wounds a bit before trying to flash a custom ROM. Thank you!
For the rom installation, after unlocking your bootloader and rooting, download the app Flashify from Google Play, then install TWRP or CWM zip file as recovery image. Then, from there, you can install custom ROMs or make backups of your phone, etc. A cool custom ROM I recommend is CyanogenMod, it ports newer versions for older devices. So, you can have Android 6.0.1 in your phone
