Device doesn't boot up because it needs a password?

Hi,

i already thank you for all answers. There's a big problem with my device.

It's an OnePlus 3 with the MarshROM. Everything worked completely fine until i wanted to install SuperSU via recovery. It showed up that it needs a password. But i never did this password! It's none of my known passwords, so what should i do now?

Thanks for your answers and I apologize for my english.

Can't get file onto HTC One M9 because I don't have adb. How?

I have an answer to this. I had the problem, then I found the solution and now I'm sharing it:

Problem: I tried to put SuperSU on my M9 with CM-13 because I thought I needed root (you don't, under developer options there is the ability to turn on root essentially). So I flashed SuperSU from an apk and then it auto-updated itself then rebooted and got in a start up loop! Now I couldn't access the phone via adb, I'm not sure why. I think USB Debugging was off, but I'm not sure. AND I had not installed SuperSU from a zip so I didn't have that file laying around! So I went and got the latest SuperSU which I heard would work (it did) here: http://download.chainfire.eu/969/SuperSU/ THEN....how do I get it on my phone? I mean, who has a micro-SD reader laying around...not me today.

I DID have fastboot working but not adb. SO....I went into my phone and launched recovery mode then I chose this new thing called "adb sideload." That turns ON MTP so your phone comes up technically on your PC via USB but it doesn't show under my computer. But then I was able to go to my command prompt and type "adb-killserver" then "adb sideload NewSuperSU.zip" and it loaded!!! And I could then boot in!

Now I'm sure I shouldn't have SuperSU running but at least now I can put all the needed binarys (like CM and gApps to get started if I needed to from scratch) on !!!

So it works now.

Strange behavior of phone because of bad battery

Hello all

I dont know the right place to ask about my problem so I apologize in advance.
I own an Leeco Le X600 phone and up until next week it was working fine.
A new marshamallow came out and I updated it gtom lollipop without an issue.

This weekend everything changed.
I wanted to copy some pictures to my computer so I plugged the USB cable and nothing happened.
The phone vibrated but didnt recognize the usb connection nor the computer recognized the phone.
I decided to reboot the phone hoping that would fix the problem when I first encountered the problem

The phone would boot to the logo screen and then reboot again in a continuous loop.
I tried to get into recovery mode thinking that I would reinstall the firmware 15s but the logo would show Recovery but it would just reboot.

I finally figured out that plugging the USB cable to either the computer or charger the phone then reboots normally (in recovery too).

I have since done factory resets, reinstalls of the firmware with no change in behaviour.
The phone was unusually warm all the time and today I charged it to 100% and basically just let it sit unplugged without using it all day and the battery was empty in about 7 hours.
So its safe to say that the battery is busted.

I can order a replacement battery, they are not very expensive but my concern is that while that should fix the battery life would it fix the other problem with the USB connection and booting issue?

When the cable is plugged the phone vibrates which indicates to me that it recognizes it but it just goes into charging mode and doesnt give the options for data like I simply plugged into the charger.
I have tried different cables and different computers.

Anyone has seem anything similar and know if a battery replacement solved the issue?

Mobile Data much too slow, cant unlock phone because mmi codes are invalid

Hi,
following problem to my LG P930:
I got it as a present because my old phone was crashed. First I wanted to do with the P930 is to get root access and flash CM to it. This was difficult enough, but now I have a problem where I coundn´t find any information.
With original firmware (I think it was 2.2.6 or 2.3.6) LTE was working. Now, with the last CM 11 and with CM 10.2 LTE dowesn´t work. I can ping any homepage with the terminal, but the speed for downloading is just at 40k/s, really really slowly.
I found, that maybe LTE must be unlocked by an unlock-code. Therefore I have to open a menu under the number 2945#*930#, but when I call this, just the msg appears, "Connection problem or invalid MMI code". Most of all #* calls do not work at all!
I tried to fix it, but all methods I found are for MTK devices, but the P930 has a snapdragon cip.
The *#06# call works, my IMEI is valid, I can make calls and send sms, the Internet works, but much too slow for daily use. My Sim Card gets access to o2 network in Germany.
I tried 3 CM ROMS and different settings in APN and mobile networks, but nothing works.
I tried to get network access with a Telekom SIM, but there I couldn´t get any access, so I wasn´t able to make calls, neither sms nor Internet.

does anyone have an idea how to solve this issue? Is that correct, thinking that mobile data doesn´t work because the phone is unlocked?

PS: only thing I found is in this thread, is to rename modemfs folder.

But I don´t understand what eduds mean in post 8, and his problem is not exactly the mine, because his mobile data doesn´t work at nothing.

Thanks for response, regards from Germany
