I think his fastboot might be corrupted? Or the partition tables are messed up. Maybe he could try the Color OS flash method for hard brick? But that'd require getting to 9006 mode.

I'm new here, so I might be wrong

Ok so here's what seems to be a common theme here:

All users that have reported this are using twrp. And almost all have wiped internal at some point. Not sure if there's a connection but it does seem odd. I do not recommend anyone wiping internal when flashing. Its possible that the recovery is causing issues when wiping internal but I'm not 100% sure.

i cannot find the zip to backup the efs... :( Dam. anyone here have the possibility to help out? Or i can only use commands?
[ONE Q&A, Help & Troubleshooting] Ok_Kaleidoscope5109:
When you did a restore, did TWRP 2.8.0.1 prompt you to try to restore modem_st1? I think that's where I went wrong. I really caution anyone using TWRP 2.8.0.1 as its the one that screwed me over.
[ONE Q&A, Help & Troubleshooting] playya:
Come on man where did you look there are two twrp recovery threads and its not like there are a lot of pages to read. Its really not that hard to find at all if you just read away. I even gave you his name although I spelled it wrong :silly:

Hey its not like the adb commands are difficult though and if something happens you may need to know how to use them

No It didn't ask me to restore modem_st1. TWRP 2.8.0.1 is the culprit almost guaranteed cause I did a full restore using 2.7.0.1 and it was fine. I would also caution anyone using 2.8.0.1. AVOID TWRP 2.8.0.1 LIKE THE PLAGUE

---------- Post added at 06:35 PM ---------- Previous post was at 06:32 PM ----------

When you say wipe internal do you mean wipe internal sd or do you mean wipe system, data, dalvic and cache?
[ONE Q&A, Help & Troubleshooting] Negan:
I briefly looked at your zip. Looks good. You should actually make a thread for this to make it easy to find. Or I can add it to my op if you don't wish to make a thread
[ONE Q&A, Help & Troubleshooting] Negan:
Yes I mean people wiping internal SD when flashing. Its not needed. In a perfect world it wouldn't hurt things. But things aren't perfect and something is wrong which is causing this issue. So for that reason I say don't do it. All that is needed when flashing is to wipe data/factory reset and to wipe system. Caches are automatically wiped in this processes so there's no need to wipe them separately
[ONE Q&A, Help & Troubleshooting] tdamocles:
I never wiped internal sd when my phone encountered corruption. All i did was use the official twrp and it corrupted.

This is one of the many issues I ran in to that same night.

Seems like my EFS is corrupted. I've followed the guide to the T and nothing seems to work for me. Entering the command in TWRP terminal borks my wifi, and the only way to fix it is by flashing colorOS, but that only restores my WiFi capabilities and not my mobile data. I'm at a loss. I've returned completely to stock a couple times, tried flashing the radio/modem files, etc and nothing seems to work for me.

Yes sir. Seems like I have exhausted all software-related fixes so I'm going to try and get a replacement from OnePlus.

* Flash ColorOS from this post: https://forums.oneplus.net/threads/rom-official-4-3-coloros-v-2-0-0_beta.79203/

* Download and install OTA updates for ColorOS

* Flash back TWRP

* Flash 44S (Pre-Rooted)

* Boot up phone without SIM in (at this point I checked the settings and to my joy saw that baseband wasn't unknown

* Power down, insert SIM in, reboot

Could I ask if this fix will work for the OPPO_NV_Backup: The NV partition is invalid! error where you don't have any signal? I went into fastboot, and then successfully did the erase and flash persist.img step, but when I booted my phone up afterwards, it still could not connect to mobile data networks or receive any signal. I've already confirmed its not a SIM card issue either.
[ONE Q&A, Help & Troubleshooting] NikoZBK:
Did you flash ColorOS through recovery, or through fastboot? I had the same issue but flashing every .img manually in fastboot fixed my issue. See my earlier post.

Cant Flash the persist

First of all, thx for your post:D

I follow the steps until (fastboot flash persist persist.img) the command. and it said (error: cannot open' persist.img') can you help me plz?
[ONE Q&A, Help & Troubleshooting] Negan:
Your issue is one of two things: either your drivers are not configured (if so use the search feature in this thread and type in "drivers" and you'll find lots of info)

Or you are not opening a cmd window where the persist.img you're trying to flash is.
[ONE Q&A, Help & Troubleshooting] sg01fc:
No TWRP, not unlocked

OK, so I've tried pretty much everything (I think). My phone works fine on a custom ROM, except I can't return to stock. I did the advanced CMD in TWRP to put in the make_ext4fs /dev/block/mmcblk0p15 command that was step 2. When I go back to bootloader and type fastboot oem-device info, it still shows that my device is locked. So I tried the fastboot oem unlock and it rebooted into recovery. I then rebooted back into bootloader and try the device info again, it still shows as locked.

Let me back up. I unlocked the bootloader and loaded a custom ROM about a month ago. When I tried going back to stock using both fastboot and a toolkit, it said that my phone was not unlocked so nothing could be flashed via the fastboot mode, so I can't flash any of the images.

I am pulling out my hair trying to get it unlocked again and it seems that I can't without TWRP installed. I must be missing something.
[ONE Q&A, Help & Troubleshooting] Negan:
Why are you going back to stock?

And there is a thread for this as well (unlockable bootloaders/ reset tamper bit or something like that.)
[ONE Q&A, Help & Troubleshooting] MarcoSeven:

What driver I need actually? if you can help me, can you link up the name of that driver or the download link? :eek: thx!
[ONE Q&A, Help & Troubleshooting] Negan:
I'm going to ask you to use the search function and search "drivers". You'll easily find what you're looking for
[ONE Q&A, Help & Troubleshooting] sg01fc:
Reasons

I am going back to stock because for the three months that I had it set up to stock, I never had rebooting issues. As soon as I started with new ROMS, I was getting three to four reboots a day. Yes, I did wipe the cache and dalvic every time I flashed a new ROM.

Thank you for pointing me in the right direction. I had tried multiple "return to stock" threads and never saw anything about resetting the tamper bit. I'd never heard anything about tamper bit before, so that was why I had not searched for it. I am still learning the Android systems, so learning will help me in the future.

Thank you for your help. The reset tamper zip fixed my problem.

Signed on only for this

I signed on only for this. I live in Libya, a place where technology is still very new, and devices like the One Plus One don't exist. Even if my device a common one, very few people know anything about android or that kind of thing.

I had the boot loop problem and after a long time (like 2 weeks), I finally figured out how to use the adb bridge and kept flashing roms. Keep in mind, the internet here is horrrrrrrrrrrrrrrible, so each time i download a rom, it takes forever. Just like it took me forever to get on this webiste and sign on.

So basically, I signed on just to say this,

[ONE Q&A, Help & Troubleshooting] Vleiss:
The OnePlus One of my dad has the unknown Baseband/IMEI problem, and I can't get a mobile signal. Wi-fi works though.

This suddenly started (2 days ago now), without any reason at all. It's his first smartphone so he doesn't know anything about modifications. The phone was running on the stock CM version, the way it was shipped.

I have tried about everything I could find (factory reset, flashing ColorOS, deleting modemst1 and modemst2, you name it).

I did NOT make a backup of the EFS partition (who would even think about that, if you are just planning on using it the way it shipped).

Is there anything else I can do?

Also, what would happen if I take the EFS partition from my own OnePlus One (he bought after me ;) ) and use that to restore the one on the bricked phone?

I had tried your method albeit with the 2.8.4.0 and only managed to get wifi going. however, after the clean installation of the rooted 44S. there was no wifi let alone baseband. I will try other colour OS version. Did you do a clean install? or dirty flash over Colour OS?

since i have wifi going on colour os...is it possible to backup that perticular part of the efs? what does modemst1 and modemst2 do?
[ONE Q&A, Help & Troubleshooting] anishz:
I clean flashed 44s, I didn't try other color os so cant advice on that. If baseband is showing in color os then yes you can backup that. Modemst1 and modemst2 are the files that get backed up when you backup from TWRP. Don't exactly know what they do.
[ONE Q&A, Help & Troubleshooting] ROBINGAZI:
Did you backup your EFS whilst in colouros or after you had flashed stock?

Hi Mark,

I hope your well,

So ive had my OPO since september and has been perfect. Kept it stock just a few apps no root or anything, the other day i was listening to spotify, as you do, and it just rebooted. I thought its just normal so i started listening to spotify again and then the misery started to happen.

For the full day it was in a bootloop on the cyanogen mod logo - i was at work so couldnt do anything. i tried to charge it. reboot it, nothing.

so i went home, downloaded a file from Sanam, the offcial oneplus one website and followed the instruction but now it there is no boot loop but just keeps rebooting and flickering once on the set up screen.

So then i found this article and downloaded the full package, all drivers have been installed. in putted the command instructions. (fastboot erase persist and fastboot flash persist persist.img)

But now, everytime i open up an app, for eg. chrome, camera it just reboots.

can you please help me out.

thanks

Please help me

Hello all,

I just got my OPO yesterday and was a little disappointed that it wasn't the international version (it was from my dad who got his friend to bring it from China) and therefore couldn't access Google Play etc. so I decided to change the OS to CyanogenMod. I tried following the easier version of it (without doing the commands through a computer) and succeeded after a few tries. However, I can't use it to call/text/access internet. Wifi is ok though.

I hadn't backed up anything as I thought it didn't need to (I know next to nothing about phones and software etc) and now, after searching online for a while I think I might have permanently deleted the EFS? The IMEI shows up but IMEI SV is 00..

This seems like a very active thread so it'd be great if somebody could help me. I don't want my dad to see I've somehow stuffed it up already...
[ONE Q&A, Help & Troubleshooting] nadiros:
Hey, I don't know what it means, however my IMEI SV is 00 as well and my phone functions normally. I thought I recalled an actual number there at some point like 02 but once again I can't say for sure.
