After rooting my phone I tried to reboot in recovery mode but got stuck with fastboot mode started udc_start().
I have been reading all the guides out there but got more confused. Some of them didn't work, some skip steps, some are outdated etc.
What I did:
I wanted to root my phone because I had only 30 MB free internal space.
I used SuperOneClick to root the phone. At some point it said that I was missing a file and asked to install it.
Without thinking too much I clicked No. Then the root finished successfully.
I had SuperUser installed and also used Root Checker to see if the phone was really rooted. It was OK.
After that I installed ROM Manager and Titanium Backup. I backed app most of the files with the Titanium.
Downloaded CM 7 in my SD card in order to do a clean install and free some space.
Then installed CWM with ROM Manager. Finally in ROM Manager I clicked Reboot in Recovery mode.
When it did, I got the fastboot error thing, and I'm stuck since then.
Some facts:
When I got my LG P500 it had Android 2.2. It was my first Android phone. After a while it said a new version was available, I think V 20b.
I clicked download and install. After downloading the phone rebooted and I was waiting for 7-8 minutes and it didn't boot.
At that time I didn't know that an upgrade can take time, so I thought that the phone was stuck so I turned it off.
After that I turned it on again and found out that I had Android 2.3.3. And the phone worked without any problems.
The only problem was that I had only 30 MB free internal space.
Can somebody please help?

Hello everyone, this is my first post on your web site. I have spent the past 6 hours nosing around xda's web site trying to find a simple straight forward answer. Heres my situation, I unlocked the boot loader and installed tenfar cwm. I re-booted my phone and everything was fine. I then continued to download the gingerblur .zip file and copied it from my pc to my atrix on the internal sd card. I shut my phone down and went into android recovery and created a backup of my current oem rom right after I gained superuser access. I assumed it created the entire back up since it was date and time stamped as this website said it would. I then re-booted my phone and went back into recovery and installed the .zip gingerblur file from the recovery program. Once I did that it installed through the recovery program and gave me an option at the top of the recovery program to install from internal sd, install from external sd, or back. I selected back and kept clicking back until I got to reboot the device. Once I clicked reboot the device from android recovery mode my phone went to the dual core screen and stayed there for approximatly 45 minutes before I pulled the battery. After that I can not get past the dual core screen. I have "unlocked" still displayed at the top left corner of my screen and I used the automatic unlock script to re-install tenfor cwm. I cleared all of the cache, data and tried to restore my phone from the backup I performed earlier... it says it successfully loaded the boot load image but all of the other images it gives errors. Needless to say I have a phone with essentially no operating system. I read a thread on XDA's website stating it could be a problem with the version of cwm I am using and with that there is a link to another thread stating to download a recovery.img file and flash it through fastboot. I can not find out how to flash it through fastboot. Any help from anyone would be greatly appreciated. I am sorry this is so long, but I would rather someone trying to help me have the whole story then just a portion of it. Please help me!!!!!! Thank you for taking the time to read this. My question is simple, how do I get my atrix back to the state it was in before I decided to try to install a gingerblur rom.
I've fixed this problem by wiping everything and installing a fresh copy of gingerbread 4.5 beta. Up and running again!!!

Hello everyone,
Welcome to a series of unfortunate noob events;
All I wanted was to set my default storage to SD, since my Samsung Note 8 GT-N5120 only had 16 gb of internal memory.
I am aware that with my device, I can move apps to SD, but only a part of it gets moved, a huge chunk still stays in the internal memory (i.e 60 mb of an app goes to sd and 100mb of an app stays in memory).
So I searched online and all signs lead to rooting, in order to tweak my device to its fullest ;therefore, making the feature I want available at my disposal. And so I did, I followed tutorials correctly, from usb debugging mode to using odin. SuperSU was there and I downloaded Root Checker just to verify.
My device was working perfectly, but during bootup instead of a screen that shows the android with a pirate patch, it shows a static white screen before going into the samsung logo screen. I've searched through the forums and found out that other GT-N5120 owners had the same problem as well. It was no big deal and I didn't mind.
After that I searched online on things to do after rooting my device. It says install a CWM for better recovery options than what the stock recovery offers, so I did I used this tutorial: droidviews.com/root-and-install-cwm-on-samsung-galaxy-note-8-0-gt-n5100-gt-n5110-gt-n5120-all-models/
Everything was fine and I thought I was getting the hang of this thing, so I moved on to the next step and downloaded ROM Manager, to use a Custom ROM, I used this tutorial: androidtipsz.com/how-to-install-a-custom-rom-on-your-android-phone-using-rom-manager
This part got hazy,
ROM Manager asked me what version of CWM I am using and the options were: 2.0 or 5.x+, I picked the latter
and I was all set,I just needed a Custom ROM to use I picked Paranoid Android. Went to their site downloaded the .zip file that corresponds to my device and used ROM Manager to flash Paranoid Android, but it got to a screen that says my .zip file is for GT-N5120 your device is GT-N5110, which was weird because anywhere I checked on the device (including ROM manager, except when it gets to the said screen) says my device is GT-N5120.
This where the unorthodox noob of myself comes in:
Without hesitation I downloaded the Paranoid Android .zip for GT-N5110 and flashed it with ROM Manager. It worked, the tab still boots and Paranoid Android is running, but the tab got laggy and Google Store stopped running and Email stopped running and because of that, no games would work. SuperSU and ROM Manger didn't open too, I forgot the message tho. Keep in mind I did all this WITHOUT BACKING UP MY FILES igotrektnub :crying:
I looked everywhere for a solution to revert without deleting all my files, Ive decided to download the Stock Rom for GT-N5120, the only problem was there were GT-N5120 Stock Roms from different regions, I think that my tablet was from the Sweden Region so I went ahead and downloaded that.
Question#1
Should the Stock Rom I use be region specific? If so how would I check which region my device came from?
So I went to Odin Mode again and flashed this MD5 file:N5120XXDNE4_N5120AUTDNF1_N5120XXDNE4_HOME.tar
it was ok but it got stuck on system.img for a good 2 hours or so? So I did the unthinkable, turn off the device...
After that every time I turn on my device it just boots to the white static screen and never gets past it, I can still go to download mode and recovery mode, but thats about it. I think my recovery mode went back to stock. I tried flashing the root files CF_Auto but it didnt do anything, the same for the CWM, I went into recovery mode factory reset and data wipe and cache wipe, but it still wont get pass the static white screen.
Please help, Ive read somewhere that as long as it still boots download mode, it can still be fixed. :fingers-crossed:
Sincerely,

Hi all. I have been trying to update my VS980 to Lollipop for a week now; I've tried absolutely everything I can think of / find in the forums, and nothing works.
The basic problem is this: I have a rooted (via Stump Root) Verizon G2 running stock 4.4.2. I wanted to upgrade it to Lollipop, so I unrooted with SuperSU and tried to OTA update it, but somehow it still knows it was once rooted, so the OTA fails. I have tried MANY things to fix/work around this, but here are the highlights:
Hard reset. The hard reset procedure completed ok, but when I try to then install the OTA update, it fails with "Err: 1117008." Settings -> About Phone still shows "Status: Rooted," even though I don't actually have root control anymore.
Use LG FLash Tool to flash back to factory stock: VS980011A_01.tot. Tried two different computers, using both Vista and Windows 10. Failed because the proper LGE Mobile USB Serial Port driver was never found/installed by Windows (despite it clearly working in the video).
Copied a text file called RCT_security containing "forel.lee" onto the SD card, b/c somehow that's supposed to reset the status to "unrooted." It didn't.
Re-rooted with Stump Root, manually installed TWRP to try to flash a ROM that way. Phone is now rooted again, but attempts to boot into recovery result in "secure boot error," and no TWRP.
Installed Quick Boot to boot directly into recovery. Fails with same "secure boot error."
Installed FreeGee and TWRP Manager, b/c now I'm just grasping at straws. FreeGee hangs on a black screen and does nothing. TWRP Manager tells me that TWRP is already installed; haven't tried using it to flash a new ROM from here, b/c that feels brickish.
Use AutoRec to fix the "secure boot error." Fails b/c running AutoRec results in it hanging at "checking for loki....installing," When I backed out after many minutes, I got an error that said "Tried to install Loki Tool, no luck."
I am out of ideas. I am pulling my hair out. The phone is working fine, except that it's stuck on 4.4.2. When I started, all I wanted was a working version of Lollipop, even if it was stock/unrooted. At this point, I'm so mad at Verizon/LG/Android for making this process so painful that I really just want to flash the latest CyanogenMod just for spite. But really -- I'll take anything.
Help?

VICTORY IS MINE. Here's what I did:
I decided to focus on the LG Flash Tool as my best potential for a successful outcome, and I further decided to focus on the LG drivers, which didn't seem be installing properly. So:
Nuked my computer and installed a fresh version of Windows 10, to ensure no errant drivers were present.
Installed LG United drivers from the top of this page: [link deleted b/c xda won't let me post it] (LG VZW_United_WHQL_v2.16.1.exe)
Connected the phone in Media Sync mode and waited while Windows installed some more drivers.
Connected the phone in Internet Connection -> Ethernet mode and waited while Windows installed yet more Drivers. (I think this may be the step I missed in all previous attempts; once this was done, the correct LG driver appeared in Device Manager.)
Installed LG Flash Tool 2014 (download link in the description of the below video).
Followed the instructions in this video: [link deleted b/c xda won't let me post it] ...
... to install VS98027A_05.kdz, which I found somewhere, but now can't remember where. But it's around.
Once all those elements were in place, it worked perfectly. Got a completely stock phone, just like the day I bought it. Immediately installed 3 software updates and am now on Lollipop.
I'm still not sure which parts of this puzzle mattered and which didn't, but I *think* the key was installing those specific drivers (and not the many other versions of the same that I came across while researching), and THEN connecting the phone in MTP mode (ethernet) -- because that's when I finally had the correct drivers appear in Device Manager. Once I got there, the LG Flash Tool worked the first time.
Right. I hope this helps someone. I lost two weeks of my life to this (and a perfectly good CentOS box).
Last thing: download mode for me doesn't work quite the way anyone describes it. I have to turn it off, hold the UP volume button, plug it in, then let go of the UP button briefly and then hold it down AGAIN. No one mentions that last part.
Hey guys, so I rooted my honor 6x without a hitch. Everything went smooth with the help of the XDA community of course. I wouldn't say I'm a noob but I don't know it all either.
So after about a week of playing around with my rooted device, I decided to go out and buy a micro SD card so i can have some more storage and be able to move files around easier. I inserted the card while I was booted into TWRP. I then immediatly loaded a copy of my backup on to the SD card. Nothing failed. When it finished I rebooted like normal except this time my phone did a hard reset. I was never prompted or asked to do this. So that was a little wierd. After it booted up everything was gone. SuperSU. Everything. So I try to boot into TWRP and I'm no longer able to do that. I'm only able to boot into recovery where it gives you the option to recover via WiFi I believe, reboot or shutdown. I tried the recovery thing while connected to WiFi and it failed. When I go into file explorer all my files are gone as far as I can tell, but the wierd thing is that all the space is still taken up just like it was when it was rooted. I only have about 12 gigs of internal storage just like I did when I had TWRP, and SuperSU loaded except it's all gone. What happened? And how do I get my rooted phone back?
I am running stock ROM and have bootloader unlocked and TWRP already installed. The phone was rooted without problems. I was getting an error from Super SU, so I looked up how to fix it online and the suggestion was to install an older version and then try to upgrade it. It was hard to find a zip from a legitimate source but once I found it, TWRP did not show the directory I was looking for (this was previously available when I rooted it). This is where I did something stupid and looked around in the settings and found the Slot A / Slot B option. I switched from B to A and the phone got stuck on the boot animation for several minutes after rebooting. I decided to reboot into TWRP and switched the slot back to B. This brought the phone back but WiFi is off by default and whenever I try to turn it on, it doesn't change.
I have seen a couple of other people mention similar issues about losing wifi after a root or changing the slot. What's the fix? I am wondering if there is anything else "broken" after the slot change and if I should do a factory reset (I would hate to do that as I was almost finished setting up this device). I have also received the error message saying "Process System isn't responding" in the settings menu a few times. It also seems like the finger print scanner isn't recognizing fingerprints any more and face unlock isn't working
One possibility is, that SuperSU isn't that compatible anymore. Magisk does a wonderful job and no problems so far. Maybe you should give it a try and switch from using SuperSU to Magisk.

I had the same issue when I first got my 6 when I was playing around with the slots. Also my original TWRP install for some reason would crash and reboot whenever I plugged in the data cable while in TWRP. I ended up flashing back to stock OOS 5.1.5 through fastboot (used the flash-all command) and then reinstalled TWRP and everything has been working great since then.

The instructions I followed already installed Magisk to the phone. I wanted Super SU because some of the other chainfire apps like Liveboot and rooted apps like Titanium backup said Super SU is needed (Titanium said Magisk will work but may not be reliable for some newer versions of the ROM). I can live without liveboot but really need Titanium to reliably transfer data from my older phone.
To be honest I didn't know they did the same thing (magisk and Super SU). I am curious now, what if I factory reset my phone and attempted to install Super SU instead of Magisk this time?
If I do a factory reset (let's say I want it just like it was out of the box and I format the data partition as well), will I need to root the phone again? I am asking because I don't know which part of the instructions I should ignore. I am sure TWRP will already be installed after the reset so I would only need to install the extra apps...
You don't have to format data. Just factory reset it. Then use "fastboot boot twrp.img", don't allow modifications, flash a kernel you want (if you want one - I really recommend ElementalX) and then the latest version of Magisk (16.4 BETA currently). Did so - all fine. And yes: Even Titanium Backup works without any issue with Magisk.
We had similar problems with TWRP on the Razer Phone when it was new. We solved the problem by using the TWRP boot image to flash the stock boot image and then flashing a TWRP zip. I just got the OnePlus 6 yesterday and haven't really messed with it yet but everything sounds the same to me so far.
I read more about TWRP and realized what I was doing wrong when the directory with zip files wasn't showing up. When TWRP showed up I was supposed type in my regular unlock password to decrypt storage. When I did that the folder I was looking for showed up. I made a backup through recovery (which took like an hour, may be because the external flash drive I attached was really slow - and the size of the backup was about 12GB). After that I installed the zip file for Super SU, just to see if it worked - it showed the installation was successful but the app was still missing from the app drawer. Now I wanted to factory reset the device and start over.
I went into wipe and there was nothing listed under the wipe screen. I went into Advanced wipe and wiped whatever was selected by default. The selected items were Dalvik / ART Cache, System, Data. There was also "Internal Storage and USB Storage" that wasn't selected.
I swiped to wipe, it wiped everything. Then asked reboot, I rebooted, got a blank screen with white LED for a long time. When I plugged it into the computer it recognized the device as Qualcomm HS-USB Diagnostics 900E (COM4). I rebooted it by holding Power + Volume Up + Volume Down. I tried to boot into boot loader next. This brought me to another blank screen. The computer still makes a noise when it reboots but screen stays black. The only message that shows up is the one saying boot loader is unlocked. Did I brick my phone? This keeps getting progressively worse.

OK good news! I tried one more time and fast boot showed up. I was able to get into recovery. I have the backup so I will try to restore that. I don't know what to do after that. I am thinking wiping without getting into advanced mode.

When your phone booted straight into that mode with black screen and the led, then you bricked it. Same happened to me 2 days ago. The solution was to use the Msmtool from another thread and it worked great. Just follow the guide. But it will wipe your device. And you have to install oxygenos manually via "local upgrade". If you have a question, just ask
What I ended up doing was restoring from the backup I had. This was the "bad backup" without WiFi and broken finger print and facial recognition. After the restore, I did a normal wipe (not advanced). This reset the phone to factory settings. Once I configured WiFi and signed into my Google account, Google offered to recover from a cloud backup of my One Plus - I didn't know Google made these backups. It downloaded all the apps automatically. I don't know yet if I have sign into all of them all over again.
The bad back up saved my ass, I wasn't even planning on making it. I was just testing the backup feature. That's why you should always do a backup, even if the device isn't in ideal configuration.

I rooted my phone with Magisk and installed the 5.1.6 via OTA (and reroot via installed Magisk Manager). So no need to install TWRP so far.
Titanium Backup runs flawlessly with Magisk (already on my OP 3T and my OP 5).
So give Magisk a try, I never had such an easy and reliable update as the one from 5.1.5 to 5.1.6
Helium is a great alternative to titanium.
