Update SU binary failed and phone boot stalled - Android Q&A, Help & Troubleshooting

A couple days ago, I decided to root my unlocked but running on AT&T OnePlus 3.
After a while, I was able to do it, thanks largely to the guide that naman bhalla posted here on XDA.
I tried to start snapchat, but it wouldn't let me login because I had root. Like a complete noob, I just uninstalled supersu instead of hitting "uninstall root" or whatever from inside the supersu app itself.
I then realized that was a horrible idea, and redownloaded supersu from the google play store (noob!). It said "your su binaries are not up to date. restart now?" or something like that and I selected "yes" (like a noob). It then proceeded to take ~ 20 minutes to actually update the su binaries, and then DRAINED THE BATTERY COMPLETELY TRYING TO START UP THE PHONE. The phone got physically warm to the touch while this was happening.
I've tried resetting the dalvik cache once, but the only way I was able to do that is to wait for the phone to die, then boot into recovery mode on startup.
I have two questions:
1. Is there another way to stop the phone from booting up completely? Will just holding down the power button work or something in ADB?
2. Have I significantly screwed up my phone?

Some more research (that I should have done before posting here) revealed that holding down the power button would allow me to boot into recovery again. I also remembered that I backed up my phone using Titanium Backup before doing everything that screwed up my phone. I saved that onto my phone's internal storage. Is there any way to restore this from TWRP?

[Help] Tried to flash SuperSU and now bricked

long story short. I tried to flash a newer updated copy of SuperSU or whatever to get root back after updating to 4.0.4 earlier this week.
Once I did that I was able to get back into the operating system and run Root Checker. Everything passed. I then tried WiFi tether and it kind of locked up on me for a bit. then I was able to stop it and exit out of it. I Force closed the programs. Life was good.
For whatever reason I restarted the tablet. once I did that I was stuck on the Samsung screen for at least 15 minutes.
I then tried to re-run root file and then the new updated SuperSU. Then everything went all to hell.
Then I get a message that says
"Firmware upgrade encountered an issue. Please select recovery mode from Kies & try again."
Now I can not boot into anything but recovery...
I am able to with that message on the screen, connect to Odin and proceed to run the "factory" restore. However it has been sitting at what I would assume is about 5% or so for a long time. at least 20-30 minutes. Should this take this long?
And is there anything else I can do to do a restore? I am fairly new to this tablet and I use it for work and of course I have a super full day of work tomorrow and really got to get this thing back up and going.

HTC Droid DNA Screw Up -Need help-

So, like everyone else, I rooted my phone and decided I dont need all this bloatware and other nonsense system apps.
I was foolish enough not to back up things I were removing, and nothing SEEMED important, but all of the sudden my "Htc dialer": Has stopped working.
My phone will turn on, but I cant turn it off, it just reboots without actually turning the phone off when I hold the power down.
I cant get it into recovery mode ( power vol up) and when it turns on, it goes to the default lock screen the phone comes with, and then I CANT see my home screen at all. The home button doesnt work either.
I cant get to my apps, I have to use my girlfriends DNA to beam whatever app im trying to get to onto my phone.
I can go to settings, but cant factory reset.
I tried killing the battery to get power it off, but then cant get to recovery screen there either.
I'm not sure if anyone has the system apps apk's just laying around so I can attempt to repair my phone, ( my girlfriend wont let me root her phone, but thatll be the next step if no one can help) but any insight as to what I can do would be appreciated.
Try fastboot flashing recovery and then dirty flashing the rom you were on before you started deleting things. This may help you keep your rom setup. If this doesn't work then go to the moonshine thread run the ruu and start from scratch.

Honestly I don't know where to begin with your post. Its all over the place. The phone turns off by holding the power button for 10 seconds and waiting for the capacitive buttons to stop flashing. If your phone turns on its really not possible for this NOT to work. Yes it will reboot this is normal, though once the lights stop blinking you can quickly hold volume down and power to access boot loader and power down fully from there. Recovery is accessed from bootloader too assuming you have one installed. A lot can be done from both bootloader and recovery to solve problems so finding out if you can access them is the first step. I don't understand your statement about the default lock screen showing and you can't see your home screen. Which ROM is it? Which lock screen are you referring to? Why can't you simply unlock the phone? What is stopping you from doing that? Your home button doesn't work and you can't get to your apps...meaning? You can't access the app drawer? I thought you couldn't unlock the device there is conflicting info there. I don't see how you are beaming tasks one at a time through this painful process but I would just avoid that until you've fixed the problem. You can access settings but no factory reset, why? What can you do from settings? And finally you are asking for some apk's "just lying around".....dude your issues seem severe, obviously you are inhibited from using your phone right now but someone giving you some apps won't solve your problem in fact it would probably make it worse. Get into recovery perform a full wipe and flash a different ROM. Also don't mess with deleting apps if your not sure it might screw up your system.

Alright let me try to be a little more descriptive.
So as for the lock screen, I can unlock the screen, but then I see a black screen, no home page/icons. I cant get into the app drawer, when i try to factory reset, it says "rebooting" for a few seconds, screen turns off, right back on to lock screen, sim card says preparing, and then i'm back to where i was, doesnt actually reset. As for the beaming, I can say, open system app remover or file viewer on my girlfriends phone, then beam it, and my phone will open the corresponding app. This is the only way I can get apps to open, since I can't get to drawer or go to home screen.
When I hold down the power button down, the buttons flash, I get a message saying " continue to hold for 3 seconds" it counts down to 1, and then nothing. I can hold it til my arm falls off, nothing at all happens when it hits 1, I also can't power the phone down. If i try to, the screen goes black, capactive buttons turn white, back to lock screen and phone does " preparing sim" and the network/wifi reconnect as if it was just rebooted.
I have the default rom the phone came with, I believe I have a bootloader, I used a guide from this site to perform my root. The folder I have contains distiller, dnashellroot.apk, boot_secure, busybox, su and superuser.apk
dude your issues seem severe, obviously you are inhibited from using your phone right now

The weird part is, other then not being able to turn it off/get into drawer/see home screen, everything else works. If i get a text, i can drag down and select it and it opens. If i open gmail on my GF's phone and beam it, will open Gmail and function 100%. Same goes for any app we both have that I beam.
I just used my rooting method to force bootloader up, which worked, but when i hit recovery, im looking at a picture of a phone laying down with a orange triangle/exclamation point in the center of it.

Ok - fact of the matter is that you might want to try getting into recovery via the bootloader (vol down + power from off). If you can access the recovery module from there, you are then able to click advanced (using TWRP) then click sideload. You will then need to use ADB to sideload a new ROM onto the phone, then install via TWRP. Hopefully you might even still have the old .zip for the current ROM that you're using and just really need to get to recovery.

I can get into bootloader, i tried recovery, i get a verizon screen bootloader but just resets phone after a few minutes.
At my friends suggestion i just got TWIP installed and now i'm just waiting to see what she suggests next. I figured out thanks to my advance app killer I can get to the play store whenever i need to, and then open any apps i've installed through there. Stupid work around, but hey, it works lol.

Well if you just got TWRP installed via fastboot or goo manager you should be pretty well set. Download a new ROM, reboot into recovery and install. I would suggest wiping the davik and cache - possibly even the system just to give you a fresh start.

Absolutely! I first started out on XDA when I got my first android phone; MyTouch 3g (HTC Magic). I then took my tinkering to full fledged modding where I was charging to overclock, root and unlock phones. It used to be fairly profitable, now there's one click steps for everything. Glad you were able to figure it out instead of having to take it to someone! Good work!

[Q] I believe I am bricked, can anybody help? (p769)

Before the incident, I had root, no unlocked bootloader, stock JB, v20h.
What had happened was I was trying the Font Installer app in th Play Store because of the added customization that would have been nice.
I found a cool font, and I backed up my current fonts and then pressed install. SuperSU asked for permissions like normal and then my phone restarted.
Then it was so that my phone was stuck at the T-Mobile boot animation after the LG Logo. For about 15 minutes. This is where I believed something was starting to go very wrong. After contemplating for a few extra minutes, I decided to just take out the battery and restart. Same outcome. I thought of all the things that were on the phone thus far because I had just gotten it recently, and decided that it wouldn't hurt me to just do a hard reset by pressing home + vol down + power. Everything went smoothly. Except for the fact that even after I did that, it was leaving me at the T-Mobile screen.
I decided to look on the forums for development and tried to do the unbrick method, to no avail after about 3 hours now. I used the LG User Support Tool and since I hadn't updated to V20f, I decided to do that to see if it would solve my problem. It still didn't, and I'll be honest, I'm a little upset just typing this right now.
I also tried the Upgrade Recovery option and it warmed my heart to see that the process was actually starting. But right at the screen where it says that it is supposed to be downloading something, it freezes up and nothing happens no matter how long I wait. I saw somewhere that it should be a glowing red bar, but I do not see that anywhere, it is just frozen, saying Time Elapsed: 00:12. And before anyone asks, yes, I ran absolutely everything as an administrator.
Is there any possible way to bring this phone back? Any help would be immensely appreciated. Thank you in advanced.

did you hard reset? then turn off your phone disconnect the battery, connect to the pc holding the volume up button? then try the Update Recovery?
i would just go through that process over and over until it works, theres not really a way to brick this phone i've heard...

Thank you for your reply! I have tried hard resetting multiple times, but I had removed some bloatware apps (I will quarantine them next time instead because I don't wanna go through this ever again) and I have tried the kdz method to only be stuck at 15% every time when I followed instructions to the pixel. I have tried to do it on windows 7 and windows 8. I have also tried the fastboot method by lelus, and that manages to "work" but I am still stuck at the tmobile boot screen afterwards. I have gotten the hang of the process of getting into the fastboot, but what do I do from there? I chose to flash ics xloader and uboot, but the process goes by so fast, I'm not even sure it is doing anything. The LG Tool has really gotten me nowhere, it just gives me a lovely error and then cannot continue the upgrade recovery process.
It said somewhere that after I flash through the fastboot I then have to try the kdz method, so I am going to do that now and see if it works. I don't know if there would be a difference between flashing a jb kdz or an ics kdz, but I will just do ics to be on the safe side.
I am quite happy to say that flashing the ics kdz was successful, and my phone is now up and running.
My p769BK is stuck on the LG screen. /: months
Sent from my LG-MS770 using xda app-developers app
im terrible with fastboot, i used the unlock the bootloader for noobs with an offline flash.
heres what i did to get out of bootloops....
alright, this is all from memory but the offline flash didnt work as well for me when stuck in weird bootloops.
Step one-going back to online flash---->
A---
the easiest way i found was to go to C:/windows/system32/drivers/ect/hosts
right click>open with notepad
there should be two lines at the bottom
"127.0.0.1 csmg.lgmobile.com
127.0.0.1 csmgdl.lgmobile.com"
i would cut them out and paste them in a text doc in the same folder for reference later...
but either way you should remove them from the hosts file and save
B----
Make sure your small server is closed! once you minimize it it should go down to your status bar (shttps)
Step two-LGMS---->
make sure you have LG mobile support installed or install it.
open lg mobile support
install needed drivers for your phone
power your phone off/remove the battery
put battery back in
connect it to your computer holding down the volume up button
S/W UPDATE mode should pop up, if it doesn't preform and hardreset and try again til it works (it will)
then in the top right corner there should be a button or two click them both until you see
"restore update" or Update restore or something to that effect
select that
and let it ride man
i got my phone ****ed many times and just had to keep redoing this until it worked. if your bootloader is truely unlocked you can probably go through all that again and get CM10 working, i did but im still working through kinks.....
GOOD LUCK feel free to ask any more Q's about this process if you run into any problems

[Q] Phone keeps rebooting, unable to enter the recovery

Hello,
I've had my S3 for over a year now and it has been mostly running great. Whenever I've had issues I tried to solve them by myself, but this time I was unable to fix my phone, so I must ask for help.
Here's what happened. I left my phone on my desk today and one of my co-workers fiddled with it. He opened SuperSU and then a message popped up saying that SU binary needs to be updated. He then choose to update it via CWM. The phone then restarted and upon starting shows the startup screen then it tries to enter the recovery, but instead it just shows it for a brief moment and then it restarts again. It keeps doing that over and over again. If I remove the battery and then insert it back again, the phone will turn on by itself and continue to reboot after failing to open CWM.
I tried to enter the recovery, but had no success. The phone did enter the Download Mode though, but flasing a ROM via ODIN will remove all of the data stored on the phone and I really need it. The phone is currently running Android Revolution HD 40.
Is there a way to get my phone operational again without loosing the data stored on it?
Thanks in advance.

First of all what are co workers doing messing with your phone I would seriously not be happy!! screen lock comes to mind!
As the above post said flash another recovery in odin I recommend Philz recovery,backup your data in recovery then factory reset if that does not work flash another rom via recovery or return to stock with odin. You can also boot into recovery with adb but I would try above first.
Then charge your co-worker for all the time wasted trying to fix phone
Thank you so much for the idea, I just tried this and it worked! After flashing new recovery via ODIN, I'm now able to access my phone. There was no need to flash the ROM again, as it was fine, the only problem was with the recovery.
And I still have my data!
Thank you very much again, cheers :laugh:

He's actually a good guy and I'm sure he didn't do it on purpose. He told me that he was playing a game and he tried to add more coins using GameCIH. Then the prompt to allow root access to the app came up along with a notification to update the SU binary. He said he pressed that button by mistake. I wasn't mad at the guy, I was only upset that I may lose my data.

LG K7 (MS3302): Swapping Kingroot for SuperSU caused bootloop?

Well, I just got this phone this week. It was actually a gift in fact since I broke my last phone a week before this.
As soon as I got used to the new phone. I started playing with it's guts. I rooted it with Kingroot, since it has never failed me before. Installed Xposed Framework, and flashed the 5.1.1 stuff for it to run. I had to flash TWRP to flash the Xposed Framework stuff (for some reason I couldn't get the sideload to work). Got a few modules for it. Got all my usual apps such as Facebook, ES FM, Instagram, etc. Got a few games. Spent some hours playing the games. You know, all the stuff you do when you get a new phone.
Then, I decided it was time to switch from Kingroot to SuperSU, as I do with every phone I root with Kingroot (and there were a few). I did it the same way as I have before, using w0lfdroid's method (I can't post links yet). The Kingroot app didn't automatically uninstall, but SuperSU was working. So, I uninstalled Kingroot manually with ES FM. That caused a lot of "unfortunately, com.kingroot.kinguser has stopped" dialogs that never stopped coming, and I decided a reboot might fix it.
I was wrong, the reboot did NOT fix it. It turns on, goes to the LG logo screen, goes to the Metro PCS screen, dims the background, [all of that within a minute and then] vibrates once, and then no sign of anything else. However, the phone does seem to be alive. When I plug it into USB the MTP starts working. It's also listed in adb's devices list. I can even use adb. I used adb to boot it into bootloader/fastboot, and it's even listed in fastboot's devices. It does still charge.
That damned Kingroot, I'll never use it again to shortcut through rooting. It has always worked, and I've been able to swap it with SuperSU everytime before this one. I just don't want to risk this happening again.
I'm lost on what I should do about this. What would you fella's do?
_____________________
I do have a warranty on it, but I've obviously voided that above. I could lock the bootloader back with fastboot (using "fastboot oem lock") so they don't see anything significant right away, but they could always dig in to see that I've done a lot of changing. Hell, all they would have to do is boot into recovery and see TWRP... xD
Well, I just locked it back ("fastboot oem lock" ) and I think my phone is actually coming back on, it's currently on the "Android is starting" screen optimizing app 12 of 151.
I'm just hoping the lock command doesn't reset my device like the unlock command obviously does... I guess I'll edit this with my results in like an hour when this is done (not literally an hour)!
EDIT 1: 10 minutes later, it seems to be stuck on "Starting apps." after it finished optimizing.
EDIT 2: 10 more minutes later, I'm pretty sure it was indeed frozen on "Starting apps.", so I took the battery out. I turned it back on only to see it still freezing on the Metro PCS screen... Well damn.
EDIT 3: Yet another 10 minutes later, still stuck on the Metro PCS screen...
EDIT 4: I no longer have USB debugging access, since I re locked the bootloader (which seems to have reset it, again). So now I also do not have access to fastboot. I think I screwed myself...

Click to expand...
Click to collapse
do you still have adb? if you do i can send a twrp backup
its been listed kingroot will brick you, currently the oneclick is compatible with our devices. you should have done some searchign before tinkering with your device in my opinion, if youre smart enough to unlock your bootloader .. you should be smarter in researching root methods.
youll have to reflash your device, contact goitalone - as noone that he's helped will help you with getting those files.
as for it being an ms3302 device.. i havent seen that device under our series.
