[ONE Q&A, Help & Troubleshooting] bogdan_p:
Hi,

I bought my OnePlus One (64 GB Sandstone Black) in September 2014. Since I got the phone, everything was running very quickly & smoothly. I did not have any problems with it, so I was very pleased with my brand new phone.

I did not tamper at all with my OnePlus One phone and every time there was a new OTA update, I updated it with the latest version. Currently my OPO has the latest Cyanogen OS 12 OTA updates (CM12S).

Last Friday I used my phone and everything was running very good, as usual. I shut down my phone and went to bed. The next day, on Saturday morning when I turned on the phone, it started showing the OnePlus One logo (with the text "powered by android"). Then CYANOGEN logo appeared on the screen and nothing happened. I waited near my phone for half an hour and nothing happened, it kept showing the CYANOGEN logo. It's like a cycle that never ends. So now I am facing a huge problem with my OPO: every time I press the power button, my OnePlus One gets stuck while booting, showing only the CYANOGEN logo. :crying:

Please see picture "OPO stuck on booting - shows only CYANOGEN logo.JPG".

As I said before, I did not tampered with my OPO, I did not flash it, I did not installed any ROM, I did not installed a custom recovery. Also, I did not drop my phone, so it is in good hardware condition. Every time there were new updates, I updated it with the latest OTA updates. I did not have any issues after the updates, so I don't understand why now it gets stuck on booting (especially since before this problem appeared, everything was working great, as usual).

I read through the forums, the internet and tried to find several solutions, without wiping my data. Any solution that I found did not work and I could not fix this problem (OPO stuck on booting, while showing the CYANOGEN logo). After two days in which I could not use my phone, I removed my SIM from the OPO and now I am using a normal phone (only for calls and SMS).

After my OPO gets stuck while booting, showing only the CYANOGEN logo, I connect it to my laptop using the USB cable (the same one used for charging), but I cannot access my files. Before this huge problem appeared, I could easily connect my OPO to my laptop. Please see pictures: "Connecting my OPO via USB - Installing device driver software - Step 1.JPG" and "Connecting my OPO via USB - Installing device driver software - Step 2 - Failed.JPG". I updated the drivers, but it did not work.

Ever since I got my phone, I have never unlocked the bootloader or rooted or anything of that sort.

I have never even touched any fastboot/adb commands since I got the OPO, until now, when I have this major problem with it.

After reading the forums, I started my OPO in Fastboot Mode and used 2 commands with fastboot.exe (Please see picture named "OPO Fastboot Mode.JPG")

Results below:

******************************

F:\OnePlus One tools>fastboot.exe devices

b01c5f88 fastboot

F:\OnePlus One tools>fastboot oem device-info

...

(bootloader) Device tampered: true

(bootloader) Device unlocked: false

(bootloader) Charger screen enabled: false

(bootloader) Display panel:

OKAY [ 0.006s]

finished. total time: 0.006s

******************************

I do not understand why "Device tampered: true", since I have never unlocked the bootloader or rooted or flashed or anything of that sort ever since I got my OPO. I did not tamper my OPO, so "Device tampered" should have been false.

I also tried to use ADB, but it does not work. Please see below:

******************************

F:\OnePlus One tools>adb devices

List of devices attached <--- THIS LIST IS EMPTY, IT DOES NOT SHOW MY DEVICE, SO ADB DOES NOT WORK AT ALL

******************************

I want to save my media files (pictures, recordings, clips, audio files), my documents and messages.

For other suggestions found on the forums, I did not use at all, because I do not want to erase all data of the phone.

My OPO can boot into recovery mode (Please see picture named "OPO Cyanogen Recovery.JPG"), so I can see the Cyanogen Recovery menu, but I do not want to wipe all my data and do a factory reset. I want to first save my data and afterwards I can erase all data and reset my OPO.

Problem: my OPO gets stuck while booting, showing only the CYANOGEN logo. I wait and wait and nothing happens (today I waited for two hours, the logo is still there and the phone does not start).

I want to:

1) Save to my computer my files (media files, documents) and messages (SMS and chat messages, like viber and so on)

2) Solve this boot logo issue (OPO stuck on booting, while showing only the CYANOGEN logo)

Any help regarding this problem is enormously appreciated.

Thanks in advance,

Bogdan
