[ONE Q&A, Help & Troubleshooting] bwells88:
You bet... Unfortunately I work until 7pm then play hockey at 8pm... So I'll be giving it a push around 10pm my time...

I'm clueless as to what caused it... Flashed a lollipop ROM as I always do and it just wouldn't detect my sim... Then all my nand back ups acted the same... Thought it ended up being a hardware issue with my One...

A quick search brought me right to your front door... 8)). I'll keep you posted...

[ONE Q&A, Help & Troubleshooting] bwells88:
So I successfully flashed the new persist via fastboot and the Baseband is still unknown.. 8( I also downloaded the zip and tried flashing that in recovery as well... No go... I was having trouble even doing a factory reset on the cell but managed to get it done but that was pouched as well... Went into set up and Google apps were f/c all over the place?... Weird... Even after I got a factory reset to stick the baseband was still unknown.

I'm at work again so when I get home I'm going to grab the latest factory image, lock the devices boot loader via adb, unlock it again which should wipe it and push the image... Lots of fun!
[ONE Q&A, Help & Troubleshooting] Negan:
Don't relock it. It's a pita to unlock it again from what i've read. Try the twrp terminal commands in the op

So I went back into recovery because the ROM it was trying to factory reset to is an Asylum ROM for some reason?...

[ONE Q&A, Help & Troubleshooting] Vonnegut:
What the hell are you installing?

Raycaster3?

Those error are quite common with TWRP because TWRP does mount system and userdata before the script does...don't worry about.

I tell you, your problem has nothing to do with the persist partition. I've read what you've done and i've read what you think the problem could be...but believe me, you are in the wrong thread.

AFAIK, you've screwed up the modemst1&2 partitions using the TWRP. Or you've installed a different modem (not 44S) or you've not updated the the rmp+sbl1+oppostanvbk partitions.
[ONE Q&A, Help & Troubleshooting] bwells88:
I was trying to flash Raycaster lollipop... The modem is definitely in trouble and in about phone the Baseband says Unknown, that is part of this threads header so I was hoping... I'll grab the 44s modem and flash that to see if it fixes the partition.

What I don't understand is after a factory reset, it flashed an Asylum build?... You would think it would install a stock One ROM.

Thanks for your input... 8)
[ONE Q&A, Help & Troubleshooting] Vonnegut:
Next time quote me..

If i were you, i would flash each and every partition coming with the 44S official zip http://builds.cyngn.com/factory/bacon/cm-11.0-XNPH44S-bacon-signed-fastboot.zip

Make a backup of your internal storage and data (=apps)
[ONE Q&A, Help & Troubleshooting] bwells88:
Thank you I'll give that a try after work... Thank you... 8)
[ONE Q&A, Help & Troubleshooting] Vonnegut:
Well, i'm flattered but if the modemt1&2 are the culprit i just hope you had a real backup of them.
[ONE Q&A, Help & Troubleshooting] bwells88:
While I was driving home from work I remembered that I have a TWRP nandroid from the latest CM11s build saved on my laptop... Would that have everything saved?
[ONE Q&A, Help & Troubleshooting] Negan:
Hope so. It's your efs that might be the issue. Whole new ball game
[ONE Q&A, Help & Troubleshooting] bwells88:
I tried that back up I had saved, that even had a modem saved, but that didn't work either.... so I got home and downloaded a factory image, had to unlock my bootloader as I guess I did lock it the night before, I downloaded a zip from here... http://xdaforums.com/attachment.php?attachmentid=2859187&d=1405749374 and just flashed it in TWRP... that was easy. Flashed all the files from the factory zip in fastboot mode and it booted up nice... but the Baseband is still unknown... I used a different factory zip than [MENTION=5427631]Vonnegut[/MENTION] linked because that one didn't have the flash-all.bat. So I'm still working on it... 8) fun, fun... haha
[ONE Q&A, Help & Troubleshooting] Icarus47:
I seem to be having a similiar problem to bwells88 - No IMEI/IMEI SV, Baseband unknown, no cell/data or wifi although bluetooth seems to work. Have tried flashing a factory image, various basebands and erasing modemst1 and modemst2, but had no effect. Major headache, the phone came new in this state from Amazon! I guess some reseller made a horrible mess of going from ColorOS to CM11s.
[ONE Q&A, Help & Troubleshooting] Icarus47:
After flashing ColorOS I seem to have Wifi now, mobile and data still eludes me, presumably due to the lack of IMEI
[ONE Q&A, Help & Troubleshooting] Negan:
You may have a different problem than he has. Try the methods in the op if you like. But I'd be returning it if it came like that
[ONE Q&A, Help & Troubleshooting] bwells88:
I would definitely return it if it came like that!... Mine just ended up that way although I have no idea how.

Still monkeying with it... But I'll be starting an RMA later today... 8)
[ONE Q&A, Help & Troubleshooting] Vonnegut:
You shouldn't play with things you don't know what they do just for the sake of flashing. The script you flashed in order to unlock your bootloader can be very dangerous (if you'd like to know why, read the short post exchange here http://xdaforums.com/oneplus-one/de...kit-v1-0-0-t2947627/post56940007#post56940007 )

ColorOS is made for chinese ppl. It does change a lot more then just the system and boot partition. Namely, the ColorOS flashes also the rpm, the sbl1, the reserve4, the bootloader, the modem, the tz, the persist and finally the oppostanvbk.

Who wants to come back to the international ROM (=CM11S) should know that before installing it..and they should also know how to flash back the international partitions.

The TWRP does a backup of the modemst1 and modemst2 partition (the so-called EFS). I don't know what TWRP version you have installed (official? unofficial? version number?) and i don't know if the EFS backup function works (because i made the backup myself a while ago and i don't need a new one).

TWRP just run a dd command in order to backup everything except the EXT4 partitions, but (in the past) i read that someone had his EFS corrupted after a restore (that could be the problem). We don't need to restore it every time we flash a new ROM or restore a nandroid backup...we actyally don't need to restore it at all...unless needed.

As far as i can see you manged to erase them both...and you don't a have working backup.

You've been doing a mess with your OPO. You aren't entitled for an RMA anymore: the warranty doesn't cover ppl deliberately screwing up the partitions . I'm sorry but that's the truth.

All i can do now is helping you to restore everything back to the stock..except for the modemst1&2 partition because AFAIK they are unique for every OPO out there.

If that'll work, well we are done. If not, you'll have to find an old EFS backup inside an old nandroid backup and we'll try to flash it in fastboot mode.

In order to do that, you have to learn how to use fastboot through the windows command line (i.e the Prompt).
[ONE Q&A, Help & Troubleshooting] bwells88:
Good afternoon... I never flashed anything to do with ColorOS so I'm not sure how that could be an issue... I flashed a factory image via fastboot and all is back to bone stock although the Baseband is still unknown so my problem is still there. I have some experience in adb and fastboot although I'm no expert, we all make mistakes and generally those are fixable in one way or another. I did send you a private message asking about fastboot commands but I've also been doing more research..(which is always a good thing!)... And have learned a lot. If I have screwed that unique partition that is used for the modem I'll just try an RMA and see what happens.

Flashing that "unlock" script didn't seem to be that bad of a deal as everything is OK in the recovery/boot loader area...

I've always used the latest TWRP and have never had a single issue with back ups or flashes. So I'm a little baffled as to how the problem came about, I simply did a clean flash of CM12 and lollipop gapps and the problem started. I've done that a hundred+ times. What struck me as odd is my back ups restored fine but had the same Baseband Unknown issue. So I haven't done anything haphazardly or with out knowledge of what I was doing.

Again... Thank you for your help. 8)

Chinese version of oneplus one

So i have read few pages of your instructions and i would like to ask which is the easiest way fixing this.

So I've switched sim cards with my friend and my oneplus one works few minutes just find. (full signal, mostly h+ and full wifi) After few mins phone loses everything, no cellular signal or wifi either.

It came flashed by market to cyanogenmod, previously it was colorOS. I was not able to update the cyanogenmod because it rebooted and said update failed or aborted.

Need to reflash cyanogen mod and those radio/modem settings etc?

Could someone give me straight "manual" what i do after every step if i need to start from a scratch?

I posted this question http://xdaforums.com/showthread.php?t=2964475.

Could you help me please ?

Edit : I do what it says on the OP :

* download the lite ZIP,

* flash persit.img with fastboot,

* reboot the phone, it has XNPH44S CM11s from [MENTION=1188493]Calkulin[/MENTION]. It starts, loads the configuration wizard (yes i did a factory reset) and then reboots, again and again.

I tried flash stock rom with fastboot from http://builds.cyngn.com/factory/bacon/cm-11.0-XNPH44S-bacon-signed-fastboot.zip

Not works.

I asked OnePlus support, and I'm waiting their answer.

I saw this thred on the OnePlus forum : https://forums.oneplus.net/threads/lost-signal-and-wifi-and-now-after-factory-reset-i-am-in-a-pseudo-bootloop.158344/page-2

I make

, reboot, reboot bootloader, flash TWRP 2.8.1.0 unofficial with fastboot, reboot and go to recovery, restore boot, system and data from my last TWRP backup, and that's all folks !!!

It seems that the phone has rebuilt the modemst*.

I made a backup of these files, as said in the OP.

Hi I an on 5.0 lollipo and persist backup is not to be found anywhere? I flashed with TWRP? Can you share path of the created backup?
[ONE Q&A, Help & Troubleshooting] Vonnegut:
Lollipop is quite different from Kitkat. I guess there must be something that prevents to move the file from the /tmp to the /sdcard folder.

I'm not going to investigate tho, because the problem has been fixed and Lollipop isn't mature enough yet.

If you want to backup the persist partition, just open a terminal, and write:

su (RETURN)

dd if=/dev/block/mmcblk0p15 of=/sdcard/persist.img (RETURN)

That will dump the persist.img backup to the root of your internal storage...if needed, you'll be able to restore it in fastboot mode.

You need to be rooted (of course).
[ONE Q&A, Help & Troubleshooting] nedooo:
Thanks for fast reply, i did a backup of mmcblk0p10 and mmc blk0p11 (modem efs) manually is persist.img needed?

[ONE Q&A, Help & Troubleshooting] bwells88:
Hey I thought mine was a hopeless case as well until I deleted my modems in fastboot mode... I'm not sure if not having a back up could be a bigger issue. I always keep the latest back up on my computer! Did you factory reset and have stock recovery?... If so find TWRP 2.8.1.0 unofficial because it supports efs back up. I can't seem to find a link.... Install that recovery for later.

Then try this...

Put your cell in fastboot mode and connect it to your CPU,

Open a command line in your platform-tools folder of your SDK kit,

fastboot devices

Press enter

Hopefully you will see your devices serial number

fastboot erase modemst1

Press enter

fastboot erase modemst2

Press enter

That should erase your modems...

fastboot reboot

Press enter to reboot your device

My device rebuilt the modems after that procedure and I was good to go.

If it works do a full back up with the efs folder and also make separate back ups of your modem as done in this threads OP...

Hope this works for you!
