Last time what I do is not use fastboot,

How about wait untail some one who explain some more details.

You have to use ADB.
[Nokia N1] C_Karhu:
I managed with adb, but is there a way to do a clean install? I have only flashed system.img. I'd like a clean wipe and flash boot, recovery and system. Can I do that with adb?
[Nokia N1] wodz69:
I'm not sure whether there's any value in flashing boot and/or recovery as there is a chance they're the same on both models. I'd say if it works with just system, leave it as it is
[Nokia N1] F_eLiX:
It looks like a lot of you made it. Could someone please explain it a little more detailed for the newbies (like me) out there? I will receive my N1 this week and I'd like to update it instantly to the Taiwanese version. I already rooted my oneplus one so you won't have to start with the total basics.

[Nokia N1] taoist1:
thx, I have successfully transformed from the build A5CN51C to A5FM51C . But I met a disastrous problem that the alert "process com.google.process.gapps has stopped" appeared all the time. I guess maybe it is because I have installed gapps in the custom release, but i'm not sure. How can I solve this problem?

I get factory data reset and the problem solved.
[Nokia N1] wodz69:
You have also tested that the factory reset works after flashing TW system partition which was not something that could be taken for granted. Great that it worked, enjoy your fully functional TW version of N1!
[Nokia N1] jujudeshighlands:
Thanks it woorked well except for the 2 steps above.

It rebooted in recovery with the robot and the red triangle with the message "no command".

I rebooted in a normal way and it updated normally.

So it's great.

In fact as a Linux user I didn't think to use dd command and it's finally brilliant!

Thanks to wodz69 for the dump too :)
[Nokia N1] Zidong:
Same, I also failed with that two steps and it works fine now after I rebooted it in a normal way.

Anyway, Thanks to wodz69 for the img and others' effort on this.
[Nokia N1] yahyah206:

the stock recovery lost after flashing taiwan version system.img
[Nokia N1] soondin:
N1 have custom recovery? my N1 is okay to boot and work stock recovery.
[Nokia N1] taoist1:
I messed up with these two conceptions. I mean the stock recovery cannot appear after pressing volume and power buttons together. and I have to press the power button to reboot it.
[Nokia N1] soondin:
When you on recovery. Shotly wait and press volume up + power. You can see some menu.

I googled the error,it shows due to the size of system.img too big:laugh:

did you fastboot flash system system.img successfully?:confused:
[Nokia N1] taoist1:
thx, you are right. I successfully get into the stock recovery(A5CN51C version).
[Nokia N1] palmaholic:
Thanks to wodz69 and soondin. I'm finally able to get Google Play running in my Nokia N1. However, it seems that my recovery crashed. It used to be CMW. I wonder which recovery I should install. The original one?

Pls advise. Thanks!
[Nokia N1] wodz69:
Not sure, I'm on stock recovery but I don't know if there's any difference between cn and tw versions.

You can try to flash the one from tw version - it's in the dropbox folder linked earlier in this thread
[Nokia N1] Ahbrosha:
Stock recovery

Could someone please upload the stock recovery for the N1? It seems that my recovery is broken...
[Nokia N1] soondin:
Same like system.img file from wodz69.

But this will work only for rooted.

1. Move recovery.img (use wodz69's upload) to N1's internal storage

2. ADB shell (enabled debug mode first)

3. SU (need accept at your N1)

4. dd if=/sdcard/recovery.img of=/dev/block/pci/pci0000:00/0000:00:01.0/by-name/recovery

5. wait some second. until done shell command.

6. exit su and adb shell

7. reboot to recovery (adb reboot recovery)

8. you can see taiwan ID recovery.
[Nokia N1] wodz69:
You can find the dump of my recovery partition (which should is a vanilla TW recovery) here.

https://www.dropbox.com/sh/drmfv30k54jgb35/AABc9uPxpOSUNHsV1lSD-k_1a?dl=0

PS. where do I find CWM that works on N1?
[Nokia N1] soondin:
After you boot to recovery,

Wait some second and push vol. up + pwr.

Maybe you can see this screen.
[Nokia N1] Ahbrosha:
I've flashed the recovery image with: fastboot flash recovery recovery.img but my device reboots to the bootloader when try to start the recovery mode...

Any ideas?
[Nokia N1] soondin:
If you have rooted N1, please try with ADB.

Does the tablet need to be rooted or unlocked before you perform these commands in ADB?
[Nokia N1] bebubanche:

[Nokia N1] Jimi555:
Does this work in build A5CN315?
[Nokia N1] wodz69:
Sounds like a corrupted download. I would suggest downloading again. Folks before you have successfully downloaded & flashed from this link

---------- Post added at 02:21 PM ---------- Previous post was at 02:12 PM ----------

Yes it should work.

PS. Don't try converting your Chinese N1 to a TW version after upgrading to 5.1.1 as it would definitely not work. In such case please downgrade to 5.0.x first (see this post: http://xdaforums.com/showpost.php?p=62770204&postcount=29)
[Nokia N1] Jimi555:
When entering recovery mode no option to wipe data or cache. There shows only this picture.

[Nokia N1] soondin:
When you on recovery. Shortly wait and press volume up + power. You can see some menu for wipe.
[Nokia N1] anssi80:
I have downloaded it too many times and every time sama thing. Mega says that file is 582MB, is that correct size? I don't know is this just a coincidence, but the when I checked file MD5 sum and googled with it, it gave me result where some MD5 sum wan on 1+1 phones rom. :)

EDIT: Ok, I downloaded with N1 and mega client and unrarred it with some software from play store ==> worked. Downloading with Mac (chrome or firefox) just didn't work for me. Strange, but anyway, taiwan image installed easily with soondin instructions.
[Nokia N1] Jimi555:
Thanks soondin and wodz69! I managed to change to taiwan version. :good:
[Nokia N1] xellosez:
I got CN N1 yesterday, today it is A5FM51C, thanks to soondin and wodz69.

I cant help complaining how much time "device offline" had cost me, adb really sucks!

At first I dont understand why bother rooting the device, but "fastboot flash system system.img" only gets "cannot load system.img", I have no choice but trying soondin's approach. Regarding this failure, can any one explain why flashing system.img doesn't work, i remember someone from NOKIA claimed we can flash whatever we want to.

I didn't update to A5CN51C before flashing system, it seems flashing TW boot.img and recovery.img got device ID changed, adb update A5CN51C doesnt work anymore, it pop up some dismatch message like A5CN51C doesnt apply to A5FM51C.

Please be patient on "dd if=/sdcard/system.img of=/dev/block/pci/pci0000:00/0000:00:01.0/by-name/system ", it cost some time without any notice or process bar, you will find you N1 screen turn to black(backlight still on), shortly after that command line come to life, and you can reboot to recovery in command line.

In recovery menu, I choose to wipe everything.

Now i would like to remove root, I prefer official firmware untouched.
[Nokia N1] mrfomoco:
Recently bought a Nokia N1 from Expansys USA; I believe they stock the Taiwanese part. In fact, I asked in advance and rec'd. confirmation that it had full Google services installed.:

http://xdaforums.com/showpost.php?p=62621372&postcount=4

Assuming I'm correct (that it's the Taiwan model), then I can confirm it appears to have a full complement of languages pre-installed, as you'd expect from most Android tablets.

At first boot, you are given 3 choices -- Chinese (Simplified); Chinese (Traditional) and Japanese (Kanji). But once in Settings, I could choose from any of several dozen languages.

Hope this helps!

[Nokia N1] xellosez:
My N1 is down, install TW rom cautiously

After I installed TW rom, the right edge very easily become hot, at first I did not take it seriously, but last night the screen flashed several times and my N1 seems to be broken from that moment.

It can still boot into system, but screen keeps flashing and after 5 seconds the screen goes black, the system is still running I believe, because if I push power bottom two times the screen will be back on for another 5 seconds and it resume where it was left off. During this process, the device's right edge also becomes hot.

Then I restored factory settings, nothing changed. I have submitted replacement ticket to the retailer.

No one can be sure if the failure has anything to do with forcing TW rom to a CN device. But due to I wiped everything after installing TW rom, it can only be firmware's incompatibility or hardware's defect. So I want to remind everyone that doing this could bring unexpected result.
[Nokia N1] aliablow:
Can you please give the steps needed to follow to flash the TW firmware in a clearer way? The steps given by [MENTION=3338760]soondin[/MENTION] is very vague and hard for me to follow, unfortunately. If someone can detail the steps, I would very much appreciate it. I can see that some people over here have successfully done the firmware swap, so I hope someone can post a detailed step by step guide.

Thanks in advance.
[Nokia N1] SlickRick94:
Nokia N1

Hey guys, I was wondering something. I want to buy the Taiwan N1 with google play already installed, as I dont like necessarily rooting. I found the N1 on 2 websites(eGlobalcentral, and expansys-usa). Both sites say they sell the N1 with google play, but eglobalcentral(even a employee) says that the google play apps will be deleted once the device is factory reset, and that they sell the China version.

But they say they are brand new. Are they mistaking about the factory reset deleting google play, and actually selling the Taiwan version? Or did some 3rd party company root the devices installing google play? Id really like to know if both companies only sell the Taiwan Version(especially since they deliver them to the US), or not. I just dont want to install a update, have it crash constantly needing a reboot that would cause me to lose Google play apps.
[Nokia N1] Msonata:
I got mine from eGlobalCentral. The tablet is the Chinese variant. The package had been opened before and somebody had installed Google Play and rooted the device. Gapps and root will be lost if you update the firmware - I'm not so sure about factory reset.
[Nokia N1] SlickRick94:
Thanks for the reply. And that sucks. Wonder if its the same for expasys usa. Im not really a fan of rooted device, i can root them, but prefer not to as warranties are voided, and any number of errors can occur and harm the device.

But thank you for the reply.
[Nokia N1] wodz69:
That's weird. I got mine from eGlobalCentral (somewhere around July) too but it is a TW version. They must be sourcing their tablets from different places then...

[Nokia N1] wodz69:
Not sure about that - on my device I can select from google accounts defined on the device. Possibly it's a porting issue from CN to TW. Maybe a factory reset would solve this? (try at your own risk)

[Nokia N1] Msonata:
There's a new update available for the Taiwanese N1. The version is A5FM91E. I haven't installed it yet, though.

It seems that you can also download the full image instead of a patch. I mean, I don't know but the file size is 848 Mt.

Here: ota-service.oss.fc811.com/upload/Nokia/moorefield/Nokia_N1/N1-tw2015/A5FM91E_update.zip
[Nokia N1] wodz69:
Yeah it popped up today, however I can't upgrade unless I know that there is a working root method... If anyone installs it, could you please check if the root method for 5.0 works on TW 5.1.x?
[Nokia N1] intercontinental:
Does the Taiwan version contain Google Play? I don't care about the root, I just want Google Play. Now I'm stuck in Chinese 5.1.1 (A5CN701) without Google Play. Could I install Taiwan version over this?
[Nokia N1] Msonata:
The Taiwanese version does have Google Play out of the box.

In other news, I fear that I might have bricked my N1 by trying to install the latest update.

I tried to install the full image via TWRP but it wouldn't install since I was running a CN build with a TW system partition.

I edited the updater script and eventually managed to install the zip.

After rebooting, I was greeted by a message that said something like "something something altered, press POWER to x and VOL to y". Probably because the bootloader is unlocked. The device wouldn't boot, so I booted to fastboot mode and relocked the bootloader.

Right now the device is stuck in the "Powered by Android" logo. I can't even boot to fastboot mode or turn off the tablet. It can't be recognized via adb.

All in all, 0/5, would not recommend doing what I did if your device came with Chinese firmware.
[Nokia N1] intercontinental:
Thanks for the info. Do you know what happens if I try to install this taiwan version over chinese version? When I first got this tablet it had rooted 5.0.1 and I accepted the update that it started to offer (A5CN701) and it was a big mistake because I lost the Google Play and cannot even revert to older version
[Nokia N1] Msonata:
Well, that's the thing I just tried to do. My tablet originally came with Chinese 5.02. I foolishly upgraded to 5.1.1. I then downgraded to 5.0.2 and flashed the Taiwanese system partition. I just tried to flash the latest TW update and now my tablet is bricked.

So no, I think it wouldn't work - at least not the way I tried.
[Nokia N1] Neegola:
:confused: So what's your next move concerning this bricked N1 ? I'm in the same situation : )
[Nokia N1] Msonata:
Since I can't enter fastboot mode, there's nothing I can do :/

The tablet is recognized in the Intel Phone Flash Tool Lite though. We just don't have the correct files to flash.
[Nokia N1] intercontinental:
How did you downgrade to 5.0.2?
[Nokia N1] Neegola:
Even if we got all the img files of an precedent version of system ?
[Nokia N1] Msonata:
Basically you just unlock the bootloader, boot to fastboot and flash some images from a previous version, boot to TWRP with FTRL and flash the 5.0.2 image. Although I've read that some people have bricked their devices by doing that.

I tried flashing some images but it wouldn't work.
[Nokia N1] dazeri:
I tried to update the new version to my N1, but it says after some time that it's for Taiwanese version. (This package is for FM, this version is a A5CN507)

When I reboot device after that, and check settings for version it says I have A5FM51C. So what to do?

My N1 originally came with Taiwanese version, but I did something (updated/factory reseted) and it installed Chinese version - then after that, I flashed Taiwanese version back.

When you converted the system partition from CN to TW, did you flash other IMG files ?
