New to rooting, looking for help rooting STOCK D41520C LG-90 - LG Optimus L90

Hi, I have never rooted any of my android devices before, and was hoping that I could get some help here as I have yet to find anything online. I have Stock D41520C Firmware on my device and I want to be able to install games directly to my SD card, as my internal memory has reached it's maximum. I'm not looking to install any custom ROM unless absolutely necessary for the process. Any help or walk through would be greatly appreciated as I am a beginner. Thanks

Hi, do you find any solution?

If you don't want to mess with custom recovery, etc, how can use KingRoot. It's a one click apk that roots 20c firmware.
The only problem: it constantly connects some servers (Chinese) and it's not clear why it does it. But there is a script that must be run on command line that actually removes and replace it with SuperSU, but it's not the easiest or safest procedure. To be safe, always backup. You can go back to stock flashing the kdz files (rct tool should report that the phone was rooted though).

Rooting with Goldcard

Hello all,
I have been searching for a few answers on here but I seem to have come up short. Basically, I have a non sprint hero and would like to root it. I am not sure if I am ready to load a custom rom just yet. I mainly would like to have root to do some modification to the current version I have like getting rid of the junk I dont need (peep, footprints, ect). So far, I have successfully created a goldcard with no issue.But this is where I am getting lost. From what I gather, before i can root at this point it seems I must load some sort of basic or custom RUU to even be able to get root. Is this correct? I would like to avoid this if possible at least until I can do a nand backup. I have also attempted to root using the SDK and shell on both vista and ubuntu karmic with no luck. I guess what I am looking for is a way to root without getting rid of my current 1.5 if that is possible.
Thanks for your help in advance..
Try rooting one of these ways....

I did it the second way. No need to flash a ROM, but I would flash the recovery so you can backup your system in it's original state just incase you mess with something you shoudn't
AFAIK Theres is no way to root exactly what your running or return back to stock software after root on non sprint heros. You should be able to return to your carriers software if they release a 2.1 RUU update and your willing to lose root.
Next step for you is running the sprint RUU in this guide. Step 4
Worked flawlessly on my App Wireless phone. Good Luck if you decide to go for it.

[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] Upgrading unlocked/rooted STOCK ROM Telus phone

Hey all,
So my HTC One is my first android and to take full advantage of it I rooted the phone when I got it. That is my only experience so far and I have never tried a custom ROM. I just wanted access to some of the apps that used root. Now I want to update my phone to the newest 4.3 that was just released and am not entirely sure how to go about doing it and what I need to do. I am hoping it is possible without data loss ideally. I currently have TWRP on it and am guessing that needs to be replaced to proceed. Can I somehow just take the OTA if I do something? I tried to do it but it fails in TWRP giving me:
"Updating partition details...
Processing AOSP recovery commands...
Unable to locate zip file '/data/media/[email protected]
E:Error installing zip file '/data/media/[email protected]
Done processing script file"
I am having a hard time finding the proper guide I need to help me out so any direction would be greatly appreciated. Also I have S-On if that matters
First, you must be stock recovery and stock ROM for the update to work. If I were you I would forgo the update since you will lose root.

Well I don't really want to skip out on 4.3 and stay on 4.1.2 forever. I have never flashed a custom ROM so I assume that all I need to do is restore the stock recovery to do this? Or is there more to it? The loss of root would only be temporary though right as I could just re-root right after the update
Any one able to help me? I'd love to get to 4.3 and not lose my data. What do I need to do?

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

Complete Recovery and ROM installation issues

Hi everyone. Please bear with me, I did my best to search for the solution to my problem but I've run into dead ends apparently and need help!
I tried to flash an update to my stock sm-g900a, it was a while ago so I don't remember exactly what I was flashing... Basically now it says "Firmware Upgrade Encountered" and that's where I'm stuck.
All I wish to do is install a fresh ROM, whether it be stock or custom, and a recovery if needed. Every ROM and the SafeStrap that I saw seemed to require the phone be rooted, which it is not. I would prefer if it was rooted though. I simply need someone to point me in the right direction as to which ROM and recovery (if needed) to flash in Odin (I do not have an SD card) and to tell me in which order they must be flashed. I honestly thought this would have been a straight forward thing, by no matter how much I searched on here and on Google by no luck. I'm not picky as to features in the ROM etc. but would prefer root if possible.
Thank you for all your help, sometimes you just need a hand from a person with experience!
