A few things. First I appreciate you're trying to contribute but you're actually clogging up the thread. Quoting my entire op is actually not very helpful and takes a up a lot of real estate on the page. Also the link you posted is a copy and paste of my fix that someone posted on the OnePlus forums. Not he end of the world and not a big deal. I'm just a bit confused as to what your post and link were for.

Anyway hopefully I was able to help you unbrick your phone here at some point

[ONE Q&A, Help & Troubleshooting] oppakis:
Hello Markbencze,

Thank you for your every helpful stuff you gave us but I'm one of the persistant :).

I tried everything but now i'm asking myself if I have the same issue as your thread speaks off.

From the beginning, my OPO reboots when I have my SIM card in it. After some tries, I realized it rebooted only when my cellular data was ON.

So I used it a few weeks with no data connection (really sad...:crying:) and then I found your post.

The only way I can avoid reboot is to go with the erase modems, but my problem is not entirely gone because even if my data is ON, the APN is not selected (checked), so no data... and when I do activate the APN, reboots again.

Is this the same problem as you mention on your post? Because I can't find anyone who's having the problem only when DATA is activated? (or maybe no one had noticed that)

Thanks in advance for your help !

yeah very odd. Not a lot of common denominators yet except perhaps twrp. Not saying it's the issue because I don't exactly know right now but I saw a very similar problem with twrp with the note 3 where people were having an issue closely resembling this from restoring a nandroid.

But if enough people keep giving details we can connect the dots eventually

Never had problem with twrp on any phone.

Could be new functionality where twrp backup efs partition.
[ONE Q&A, Help & Troubleshooting] Negan:
Neither have I. But with the note 3 it was a major issue. Efs bu and restore was eventually removed as a feature. It doesn't show it as an option in the official twrp or multirom twrp for opo so who knows. Our phone is still relatively new so for biw it's still a guessing game
[ONE Q&A, Help & Troubleshooting] playya:
this is why I am always a little leery about upgrading recoveries when the one I am using is working flawlessly. It seems that 2.8.0.1 has cause a few problems with restoring nandroids. Hopefully everyone will note there recovery when coming her to try and fix their problems.

Personally I don't restore nandroids ever. I always keep one on hand from when I first get a phone. I just do a clean flash and restore my apps and data via tibu. Works just fine for me
[ONE Q&A, Help & Troubleshooting] B4kken:
You are my favorite person in the whole world right now!

I started having these issues around noon after flashing the latest Franco Kernel(first time kernel-flashing) onto my opo with Paranoid Android(wasn't happy about the battery life). With custom kernels I started seeing "artifacts" like the cpu/gpu couldn't keep up. I dirty flashed PA again to restore the kernel and decided to switch to CrDroid.

This left me with reboots just seconds into the startup process until I restored my PA backup in TWRP(seems like a pattern). that didn't work either and I proceeded to reflash cm 11s 100% stock.

Until now I've been stressed out like never before(my first "brick experience too). Thank you so much! I followed the instructions and it worked right away :) Safe to say, you are my favorite person right now!
[ONE Q&A, Help & Troubleshooting] Vonnegut:
Luckily enough, it happened to me a few hours ago so i could finally see with my own eyes what's wrong.

I've been using TWRP 2.7.1.1 for a long time now and i had only strange partial freezing lately after changing some minor settings..but i'm not sure if that is related. Anyway today, i was jumping between my 3 ROMs as usuals (in order to keep'em up to date). When i finally flashed back my main ROM sometime weird happened. Restoring the ROM didn't end with the usual vibration and the screen turning on with the swipe bar...this time TWRP just rebooted the phone automatically. I was quite surprised and i was even more surprised when the boot ended...

My clock said the i was in march 1970. My radio was dead and wi-fi too. All of the sensors were dead either.

Of course i knew what could be the reason behind all that, so i quickly checked the persist partition...and it was empty. No more setting for the the sensors/wi-fi/radio/bluetooth/gps.

The persist partition comes right after the system partition. The only way to corrupt it is to flash a system bigger than about 1.3 GB. Since my system occupy an half of the space and i was doing nothing unusual, my only other explanation is that a bug occurred during the restore.

I've seen other affected by this but now i can witeness that the only corrupted partion was the persist.

Since i had a backup, i flashed it back and everything came back to normal.

My guts say that there must be a vicious bug inside the code. Facts speak clearly and maybe this bug is not only exclusive of the 2.7.1.1 release. For experience, i can tell that i've seen ppl losing their IMEI (and more) after flashing an innocuous ROM (i mean a ROM touching only the boot and system sectors and with no oversize problems whatsoever) even when i had my old MTK phone.

BTW, markbencze, ColorOS is not something i would recommend to flash. All they need is to flash the persist.

Is there a way to backup efs?
[ONE Q&A, Help & Troubleshooting] LNKNPRKFN:
Well i had the "nightmare" for the last 4 hrs...i did an update to my PA rom and after rebooting i had no wifi and no cell (thought it was kernel issue). so i restored my backup that i made jsut befor flashing (as i always do)

and same crap, so i looked and looked, flashed the revert to stock and got the AUDIOFX FC loop.

So after searching i found this thread and to my amazement WEEE ARRREE BAACCCKKK

[ONE Q&A, Help & Troubleshooting] LNKNPRKFN:
I originally was using TWRP 2.7.0.1 which was the highest version available when rooting my opo, I did backups as usual and even did a couple restores with it. And those were flawless. I updated to TWRP 2.8.0.1 when they released it. And did a backup before flashing pa 4.6-Beta2. After I flashed 4.6—BETA2 I had no cell or WiFi so I thought it was kernel issues... Not flashed properly so I did a full wipe, restore, update rinse repeat. And still no luck. So thank goodness for this thread that saved my phone...hope this helps

Take the newest one

To push it simply reboot into twrp, go to advanced adb side load. Connect device to PC.

Open a command window in the directory where the zip is and do "adb push name_of_zip.zip/sdcard/"

The zip might get automatically renamed to sideload.zip. that's ok. Just flash it

[ONE Q&A, Help & Troubleshooting] Negan:
Ok then you're having a driver issue. You need to check on your drivers. Do you have the ADT SDK? If not you need to get it and then go into the platform tools folder and you will see adb and fastboot.exe files. Copy the cm nightly there.

Open a command window in that folder. Go back into twrp, adb shell and try "adb devices" it should give an output recognizing your device.

Alternatively if you have a USB otg you can copy the zip to it and flash it from there in twrp

Hey guys,

So At first i check the battery, the battery is OK and have 3,8 Volt. So then i tried to search the phone on my computer.

I found this guide: http:// xdaforums.com/oneplus-one/help/wrong-kernel-black-screen-fastboot-adb-t2835696/page16#post55129486.

I downloaded all and try to start the MSM Tool but the tool do not flash the phone. In the attachement i send some photos what the phone is found in the drivers.
