A5CN51C is a patch with 19.9M,you should download full version A5CN507.

http://ota-service.oss.fc811.com/upload/Nokia/moorefield/Nokia_N1/N1-china2015/A5CN507_update.zip

run command prompt in the adb tools path,such as:

then N1 reboot to recovery mode

select the adb sideload mode

C:\platform-tools\adb sideload\A5CN507_update.zip(copy A5CN507_update.zip to platform-tools folders)

then begin to flash.

Still waiting for a way to unlock the bootloader, so that i can root and install Google Play. Or root then wait for the update 5.1.1 for the Taiwanese version then flash it! :)
[Nokia N1] kokkok:
Thank a lot, I will try now. Hope everything will fine :)
[Nokia N1] aquaminh:
DO NOT update to 5.1.1 if you want to keep the bootloader unlocked. I've been trying so many times to unlock it but it still doesn't work.
[Nokia N1] kokkok:
Finally, you are an expert or noob about rooting and unlocking firmware? Are you successfully rollback to previous firmware and reroot N1 which updated to 5.1.1????
[Nokia N1] aquaminh:
No it doesn't work. Every previous tricks for rooting N1 were written while its bootloader is open. Now it's locked with the new update so maybe we have to wait for the new trick from the developers.
[Nokia N1] kokkok:
Bad news. Don't know why Nokia relock the bootloader. :(
[Nokia N1] kourcomp:
You can unlock the bootloader using "fastboot oem unlock".

but It doesn't like to boot into stock rom with that unlocked.

I'm guessing you can unlock, load what you need to load, and lock it. Have not tried it.

Waiting for the 5.1.1 update for the Taiwan version.
[Nokia N1] LineArc:
Dear a. Complete guide will be appreciated.. Kindly post the complete guide to roll back to the previous version.. As I need root and play services

[Nokia N1] bermik:
the download links dont work :( Is there a way to flash the Taiwanese rom to a Chinese N1? Please help! My N1 is on 5.1.1 right now without google play.
[Nokia N1] intercontinental:
I'm in the same boat as you and trying to find a solution to get Google Play to this device :mad:
[Nokia N1] intercontinental:
Those wo are stuck with Chinese 5.1.1 without Google Play could try this. Keep in mind that there is a possibility that you can brick your N1.
[Nokia N1] ayziaa:
I have googled "Gapps without root" apparently it seems that installing apks without root works and the playstore is available. As I do not own a n1 I can't confirm it. Does anyone ever tried it?

edit: for example this methode https://www.youtube.com/watch?v=MgeXdR92Sx0

edit2: Apparently it only works with amazon fire devices. But There is a possibility to flash .ZIP with gapps with a custom recovery is someone had the knowlege to make such a zip, it has been done for the android nokia X smartphones . I know I don't.

edit3: an example with a chinese tablet https://www.androidpit.com/forum/589877/how-to-install-google-play-store-if-it-is-not-pre-installed . I think it's worth trying.

[Nokia N1] AndyBurns:

Am I imagining it, or is the rubbish bin icon when using the Recents app switcher a new addition?
[Nokia N1] kokkok:
How can you add A5CNB19 to N1 before update without adb?
[Nokia N1] intercontinental:
AFAIK there is no way to put Google Play for 5.1.1 Chinese N1.
[Nokia N1] sasha2910:
Now that's a real problem( at least throw it out...
[Nokia N1] intercontinental:
Kind of sad really because N1 is such a great device.

You can try to downgrade to 5.0.1 version because it can be rooted and then you can install Google Play but there is a big chance that you will brick your N1.
[Nokia N1] sasha2910:
is there a manual how to do downgrade the firmware to 5.0.1?

A5CN19B images

I've tried downloading the OTA files using the format suggested above but every time the download starts then fails at around the 6 Mb download point. The download is very slow saying up to 10 hours at some points then eventually failing a few minutes into the download. We have a good internet connection. The 400 or so Mb shouldn't take long normally.

Can anyone please provide me with the boot, recovery, and system image files for A5CN19B ROM.

Thank you.

Have locked your device? If so, you should unlock it first.
[Nokia N1] intercontinental:
https://github.com/jemyzhang/iovyroot/tree/nokia-n1
[Nokia N1] aquaminh:

[Nokia N1] intercontinental:
I don't know. I haven't tested.
[Nokia N1] ArtDo:
I tried to root the device using the following http://xdaforums.com/nokia-n1/help/nokia-n1-root-t3125771

But I was stuck T4 or fastboot flash fastboot droidboot.img wasn't flashing with error:

FAILED (remote: not allowed to flash this partition)

Short note, if you unlocked Chinese device, you won't be able to run it, till you will lock it again. So this device is actually not bricked yet

I took device to service, and took it back in state that of bootloader, even if it was locked back.

So, since I had no more access to adb, and the only option I had is Bootloader (my drivers were correctly configured and the device was visible from fastboot devices)

to unbrick my device I provided next steps:

1. PC: I downloaded and flashed the

fastboot flash recovery recovery.img

2. PC: fastboot oem lock

3. N1: Using Vol buttons select "Recovery mode" and reboot

4. N1: After entering the recovery press Power + Vol Up, and you will enter recovery menu

5. N1: Wipe to factory

6. N1: Select adb sideload in recovery

7. PC: Download and copy firmware to folder that contains adb.exe. I used full A5FMB19_update.zip

8. PC: Using command "adb sideload A5FMB19_update.zip"

If you failed on 50% pay attention on the top of screen in the "adb sideload" there is Firmware recovery version. Mine was A5FMB19, and adb wasn't accepting any other firmware

9. N1: Wait for update to apply and Wipe to factory again

10. N1: Restart the device

P.S. First start can take up to 10 minutes, so let it start.

I hope this will help some one to make his "bricked" N1 work with Google services.
[Nokia N1] kvalvik:
Looks great, works just fine, EXCEPT: half way through the sidloading, it aborts the process and says, this devices for A5FCN19, not FM - what can I do? tx
[Nokia N1] ArtDo:
Have downloaded the recovery.img I attached. And flashed it?
[Nokia N1] kvalvik:
THANKS A LOT, NOW IT WORKED, I HAD THE WRONG recovery.img!!!

This was done from 5.1.1
[Nokia N1] michael147:
The same here, can not access to recovery mode "No command"
[Nokia N1] ArtDo:
You need to have a bootloader on N1 running. And it should be visible in fastboot devices on PC.

So on pc you should flash recovery first. And and only after that you will be able to enter recovery mode
[Nokia N1] michael147:
Sr my bad, in step 4 i hold power+Vol up for a long time :p

did you install Intel IntelAndroid-FBRL?
[Nokia N1] tertaipa:
This is great info for N1 owners, but I'm newbie with rooting and playing around with Android as i just yesterday received my N1 chinese version. Unfortunately i already did the update to 5.1.1 version and now i would like to have missing Google services to my device. I have tried to follow guides in many threads here but no succes so far. How to flash the recovery.img? with fastboot my computer just says "waiting for device" and nothing happens.. It would be really helpful someone could write detailed how-to with needed files and commands used.
[Nokia N1] ArtDo:
When device is loaded normally to Z-Launcher, it is available(unless you have incorrect drivers). If you reboot to bootloader (using adb tool and command "adb fastboot"), you will be able to see your device in fastboot devices. And again if you don't see it, you have invalid drivers, and you should reinstall drivers using this guide http://xdaforums.com/showthread.php?t=2588979

There is a guide with pictures you can find there http://xdaforums.com/attachment.php?attachmentid=2480396&d=1388281089
[Nokia N1] N1 Owner:
This worked for me. I had trouble initially getting the recovery menu, that is covered in a later post.

I was able to swap from the Chinese ROM to the latest Taiwanese ROM and unbrick my device. :)
[Nokia N1] tertaipa:
Hi thanks for quick replies. I have been trying this without success so far. Could you share the details for step 1 "PC: I downloaded and flashed the

fastboot flash recovery recovery.img" as so far i have not been able to do this. Im going to try this also with another computer with Windows 7, because im suspecting some driver issues with my Win 10 computer... Thanks in advance!
[Nokia N1] ArtDo:
Hurrah :)

What kind of troubles?

Did you install ADB Installer from instruction ?

If you did, connect devices, and in the Device manager update driver of your N1 according to guide
[Nokia N1] tertaipa:
I cannot flash the recovery.img and without that sideloading Taiwan image end to 50% because wrong Chinese SW in the device. I'm really newbie in playing around with android struggling with basics but i would really like to get Taiwan image flashed to China device. What state the device should be when flashing the recovery.img? Recovery mode, where droid is hood open? When i try to flash the recovery.img with "fastboot flash recovery recovery.img" it stay in waiting for device state and nothing happens. I have tried to instal fastboot and drivers several times and with 2 different computers and same thing with both computer. I am now missing something...
[Nokia N1] N1 Owner:
You need to get to the recovery menu. If you don't see the options mentioned in the instructions, e.g. Wipe to factory or Factory Reset, and ADB sideload then you're not in the Recovery Menu. There are several other menu options as well.

Getting into Recovery Menu isn't obvious. In step 4 of the instructions provided by ArtDo the the Power and Vol Up button need to be held for several seconds before the Recovery Menu is displayed.

My N1 is Chinese one which I had attempted to flash a Taiwanese ROM onto several months ago. I ended up with the tablet only booting to the bootloader (I think that's the correct name) screen.

The instructions provided by ArtDo worked perfectly. I did initially have problems getting to the Recovery Menu. Unfortunately I don't have a screen shot to show you what you should see on the Recovery Menu page. Perhaps someone else has a picture of the Recovery Menu page.

Follow all of ArtDo's instructions including the bit above the instructions about locking the bootloader, assuming you have unlocked it to start with.
[Nokia N1] tertaipa:
I can get in recovery menu with several options (sideload, boot options etc) available, but i cannot get recovery.img flashed to the devide.

And in recovery menu sideloading the actual SW is not working without first flashing the recovery.img. Damn I suck in these... :eek:
[Nokia N1] ArtDo:
Your N1 should be in Bootloader mode

And on PC when you run fastboot devices you should see your device in the list.
[Nokia N1] tertaipa:
i see the device in the list with fastboot devices. when trying to flash the recovery image i get following error message:

C:\NokiaN1>fastboot flash boot recovery.img

[Nokia N1] N1 Owner:
Is your bootloader locked or unlocked
[Nokia N1] tertaipa:
Help is really needed! now i managed to flash the recovery.img and now my device is not booting and i cannot get to recovery mode. Device boots only to the state, where i can choose normal boot, restart boot loader and recovery mode or power off. Which ever i choose i end up to the same menu.. fastboot finds my device but i cannot get further

I was going to give this device for a xmas present to my wife with google services and now i have only the bricked device....

PS: Actually I failed in step 1 when it said FAILED (remote: command not allowed in this device state).
[Nokia N1] tertaipa:
Hooray!! I finally made it and transferred China device to Taiwan device!! Big big thanks everyone here in XDA who has contibuted toN1 threads. After all, im not sure how i managed to do it as it was some kind of combination of all these guides regarding N1. One thing i remember that i had to update ADB to sideload the firmware to the device. I did it with this: http://xdaforums.com/htc-one/general/tool-updated-adb-version-1-0-32-fastboot-t2932160

Fastboot unlock

Then step 1

PS: When using "fastboot flashing unlock" command, three dots appears and nothing happens.

[Nokia N1] N1 Owner:
Most definitely
[Nokia N1] defendos:
You're my fricking hero lol, i had deleted my system partition without making a backup, and my recovery looped back to my bootloader, so i only had access to fastboot, and when i followed your intructions i couldn't get past this issue either but then i fiddles around with the steps and done it with guidance from your steps:

if device is in locked state or cannot boot to recovery i did this:

step 1: open cmd and type: fastboot oem verified, select yes

step 2: flash the recovery according to step 1 from your post

step 3: fastboot reboot bootloader

step 4: follow your guide at step 3, after my step 3

Thank you so much, i gonna post this with my own solution in the nokia forums and hope to unbrick a lot of devices.

it just says powered by android and go's to an android lying down with a red triangle with an exclamation mark
[Nokia N1] Kiryu144:
Did you found any workaround that error? (FAILED (remote: not allowed to flash this partition))

I'm also on 5.1.1, but I always get that error. The "fastboot window" on the tablet says DEVICE STATE - unlocked. :confused:
[Nokia N1] ArtDo:
Nope, for Chinese firmware it didn't work. So the only option I see, is to flash Taiwan recovery, and using recovery mode flash Taiwan firmware

---------- Post added at 10:42 AM ---------- Previous post was at 10:36 AM ----------

If you see red triangle with exclamation mark - you are in recovery mode! Press Power and then VolUp, and the menu will appear
[Nokia N1] Kiryu144:
And there isn't any save way to do it, am I right?
[Nokia N1] t1xs:
I tried to follow the route above but I am now stuck:

My Nokia N1 is a A5CN51C, i.e. its Android 5.0.2. It does not have a "OEM unlocking" option in the Developer Options section. The command "fastboot unlock" or "fastboot oem unlock" result in the message "Fail". It was rooted some time ago with the method described elsewhere in this forum but I now wanted to switch to the FM-version which seemd to have worked for others here.

I flashed the recovery.img from above with command on PC: "fastboot flash boot recovery.img" which was confirmed with "Okay".

But when I now try to start into "Recovery Mode" it just restarts the Bootloader Menu. The same happens if start from the Bootloader menu to "Normal Boot" (or if I power off the device and start it manually) - I always end up (again) in the Bootloader menu. The command "fastboot oem lock" results in the message "Fail".

The command "fastboot devices" shows the device but the command "adb devices" does not, i.e. I have no access via adb.

What can I do?
[Nokia N1] t1xs:
One addition:

I also tried the command "fastboot oem verified" which was recommended for this situation earlier in this thread. But I only get error "FAIL(unknown command).
[Nokia N1] Skyfiend:
My pc recognizes the device. But for all adb commands 'cept reboot to bootloader, recovery I used. The only thing got is waiting for device and nothing happened on my device.
