Hi, I want to share my experience. My device is a YD206 purchased from Aliexpress.

To perform the upgrade:

1 - Download the latest RU firmware;

2 - Download the latest CN (206) firmware;

3 - I copied the files from the radio folder of the CN firmware and the files of the RU firmware except those of the Radio folder in the firmware folder of YotaFlasher;

4 - I applied the flash and waited for the restart.

After several minutes the device started and started downloading a new firmware via OTA (189mb).

After the installation and reboot of the device I realized the Root, after the root I made a factory reset and the mobile started to function perfectly.

Battery - 2 days

Back Screen - Ok in black mode

Camera - Ok

GSM and LTE - Ok (Brazil)

So far everything is working perfectly.

Thank you and sorry for the poor english.

you saved me ...... normal upgrade did not work, and I tried everything.

THIS did the JOB.

Thanks.

This article is really useful. Totally recommended as I have upgraded from YD206 to YD201 using this
[YotaPhone] DTG1498:
Excuse me, where did you download the RU KitKat ROM?

I just bought a YD206 (HK) and I wanna flash it, to be a RU build

If that method is safer, I wanna try it :)

Thanks

Thank you!

Hi there,

I just wanted to thank you for taking the time to create such clear and precise instructions. I just bought a Yotaphone2 and used this post to upgrade successfully. I used the HK ROM and I'm now on Android 5.0.

There were three OTA upgrades, and now the phone is working very well.

Cheers,

Which ADB driver should I use? The one that came with the yotaflasher or the one which is included in the description?

There is a difference, but does it matter?
[YotaPhone] Fads501:
thank you for sharing the experience, I understood everything you mentioned except when you said "I realized the Root", please can you explain what do you mean by that? you mean you rooted your device after upgrading? if yes, is it necessary to root? thanks

gentlemen, I have the latest ME rom installed (build number LRX21M.5.0.0-ME1.1.60), I installed that because basically I live in the ME, this version is working great actually, but seems that latest RU is more enhanced and got more features (I guess), can anybody explain or does anybody knows whats the added value in having the latest RU installed? many thanks!
[YotaPhone] rapa123:
Yes, I think also he is meant rooted. In't not necessary to rooted your device for normal use unless if you need to install some custom fonts, etc.. and if you gonna root your phone later you have to backup everything as it will wipe all your data.

No the firmware HK1.0.3.61a is installed on the phone. The latest firmware HK 5.0.0-HK1.1.66 was extracted in the folder: C:\Program Files (x86)\yotaphone_flasher\Firmware. The "radio" inside the folder.

I've tried to flash my phone following the instructions. but just after the flashing with the YotaphoneFlasher my phone is always shows me the "boot animation looping". It is not switching on anymore. and my pc is not recognizing the adb sideload. I guess I will need to give my phone to a professional or buy another one..

Hard to say what I have done wrong. I've tried to stick to the instructions provided here.

[MENTION=8019839]Antoshka1986[/MENTION],

i have had exact the same Problem, i solved it, by doing this:

- change the USB Cable -> Use a "high quality" Cable!

- run yotaphone_flasher.exe as Administrator.

Maybe this will help you. ;)
[YotaPhone] rapa123:
press "power + volume down" buttons together until the phone is restarting.

for adb sideload "power + volume up"
[YotaPhone] Antoshka1986:
Than you guys! I will try to run the flasher as administrator. The cable is original yotaphone. I think it must be ok.

And the combination of buttons are working, but nothing is happening after that. The phone is not connecting to the computer..

I forgot to mention before that my phone was already YD201 and Android 5. All I wanted was upgrade it to Android 6. And with this instructions I have probably just deleted the system completely. I don't know.

I don't speak the IT language unfortunately and many things seem confusing ))

Thanks guys ??
[YotaPhone] rapa123:
Then what the hell are you doing here? :laugh:

You should follow the instruction as https://xdaforums.com/yotaphone-one/general/marshmellow-6-0-official-yotaphone-2-t3518062

Good luck!
[YotaPhone] Antoshka1986:
I don't know ))) I liked the detailed instructions. On the other forum site is no instructions kinda.. anyway, my phone is now dead. I need to bring it back to live somehow. Now it's just a piece of plastic :rolleyes:

Thanks mate:good:
[YotaPhone] cvzalez:
Your phone is not dead, check if you have enough battery on it.

1- Unninstall all the ADB drivers on Windows.

2-Install YotaFlasher

3-It will install on "C:\Program Files (x86)\yotaphone_flasher" if your Windows is 64 buts or C:\Program Files\yotaphone_flasher if is Windows 32 Bits.

4-Install drivers from C:\Program Files (x86)\yotaphone_flasher\Driver\Google

To do so, go to Device Manager control panel, clicking your "windows key+x", select "Device Manager", then with the right click of your mouse on your ""Computer name"" click "Add Legacy Hardware"

Next -> Install the hardware manually -> Show all devices (Next) -> Have Disk and select the C:\Program Files (x86)\yotaphone_flasher\Driver\Google\android_usb.inf -> "OK" -> "Next" -> "Next"

Now your ADB drivers are correctly installed, a restart of Windows maybe necessary, do it.

Firmware files goes to here

C:\Program Files (x86)\yotaphone_flasher\firmware, if there's no firmware folder, just create a folder with the name "firmware"

Start the YotaFlash App "C:\Program Files (x86)\yotaphone_flasher\yotaphone_flasher.exe", select the option,

1. Flash the cellphone

2. Download new firmware

3. Exit

then on your phone turned off press at the same time the "power" and "volume down" keys, wait until a message "Downloading" appears, then connect the USB cable from your phone to the Windows computer.

It should start installing the firmware. When asked to delete the user partition is better to select yes.

It will take some time, after that the start up of your phone will take some minutes also. that's why is important to have the battery recharged!

Best luck.

I may have bricked my phone

Just over a week ago I did a successful update following these instructions.

To use my Yotaphone as my company phone I had to install Microsoft Intune and select the encryption option.

But after a few days of using the phone I decided to revert back to my S6 Edge and give the Yotaphone to my daughter.

So I repeated the flashing procedure, but this time the phone is looping in the reboot sequence and I've left it there for quite a while (maybe half an hour).

Note that I did not remove the encryption before flashing. I assumed that flashing the phone would clear it, but the Intune encryption is the main thing that's changed since I flashed it originally.

The phone does not ask for the encryption password when it boots (it did before I re-flashed it, of course).

I've tried different USB cables (including the original Yotaphone cable) and running the flasher as admin.

Is there any way back from here? Can I wipe the phone completely and start again somehow?

Cheers,

Geoff

YotaPhone 2 got stuck during OTA update?

Hello,

I received new YotaPhone YD206 (4.4.3-S01-003-CN1.0.3.25a) yesterday,

let it fully charged and then I turned Wi-Fi on, no SIM inserted,

played with it for a while, fall a sleep and when I woke up this morning

it was not connected to Wi-Fi router, around 50% battery life.

So I connect it to Wi-Fi and it offered me system update to 4.4.3-S01-003-CN1.0.3.28a.

I approved it, the phone turned off, turned on again just with "Powered by Android"

and it is like that for an hour or so now.

I am starting to be afraid it will run out of battery before finishing the update.

Will it help to put it on a charger please?

Thank you.
[YotaPhone] rapa123:
Yes you can connect to the charger no issue. I had the same issue and what I did is pushed the power button until turned off then on the phone again then it showed how many apps to be updated and counting.

HK vs RU firmware?

I haven't gone through the whole thread, so I apologize in advance if these questions have been answered:

- I see that you can stop once you have installed the HK Lolipop firmware, and that the RU version is a supplementary step. What would be the advantage of installing the RU version?

- The indication that the Lolipop upgrade (HK or RU) enables 4G (actually LTE on the screen shot), does this mean that band 7 (2600 MHz) is activated?

I ordered the Y2 a few weeks ago and I expect delivery any day now. It would be sweet if the firmware upgrade opens up band 7!

Thank you for the detailed instructions! :good:
[YotaPhone] TheArt.:
RU has a few features that are more polished, not big differences.

No, band 7 is still locked. People are still trying to unlock the bands, but the firmware is not related to this.
[YotaPhone] cvzalez:
I have a YD206 and tested several ROMS, the original HongKong Android KitKat, and HongKong Lollipop and Russian Lollipop, doesn't matter which Lollipop version I have tested none gets even near of the KitKat battery time, the difference is huge, so while Marshmallow isn't stable and the battery time of it still uncertain, I would like to solve some KitKat problems:

- 1) On my KitKat ROM, the EPD screen can only be unlocked with the power button, I hate that, is anyway to make it unlock with swipe on any KitKat version?

- 2) Also on my KitKat ROM, there is no way to disable the vibration on the EPD, is there any KitKat ROM version that is possible to be disabled?

- I know I can system wide disable vibration with Xposed, but if there's a kitkat ROM that has that option I would prefer it.

How's the latest Marshmallow battery time?

Tank you in advance for any answer.
[YotaPhone] pepdavies:
Hi all, my Yotaphone is arriving today and I have the RU firmware ready to flash. If I need to flash the CN radio afterwards to get a signal does that require an unlocked bootloader? I haven't seen any mention of unlocking it. Thanks

---------- Post added at 01:28 PM ---------- Previous post was at 01:16 PM ----------

Thank you for the reply and based on your response, I happily did not try my luck (flashing again to RU Lollipop) and I remained with the HK version of Lollipop. The phone works great, but as you indicated, Band 7 (2600) is still not working. :(

I did some research, and I did notice that the YD201 version of the phone does have band 7 active, whereas for YD206 this is not the case. I find it strange that the new firmware did not open up the band as indicated in the specifications for this version. Is this possibly a hardware limitation?

Anyway, as previously indicated, other than no LTE in Canada, the smartphone works perfectly, and I am lucky not to have had any of the battery of E-paper issues reported by others on this thread, so I will stop while I am ahead. Thank you again for the information. :good:

Question

Hello,

I completed your instructions and was able to successfully upgrade YD206 phone to the latest HK version, did OTA update and then installed the latest RU version, but my build number still says LRX21M.5.0.0-HK1.1.124d and not LRX21M.5.0.0-RU1.1.134 as you suggested it should. Should I redo the latest RU version again? Not that it matters, phone works fine, but just wanted to get the latest updates if there are any available. Thanks!
[YotaPhone] Tippfehler:
You did not install the (latest) RU-ROM.
[YotaPhone] Miroslav1999:
I installed 5.0.0-RU1.1.124.zip as instructions specify. Is there a newer version than that?
[YotaPhone] Tippfehler:
If you install the HK-Rom, you will not see RU-Rom in settings and also not see the RU OTA-Update.
[YotaPhone] manuel.huygen:
I agree with Tippfehler, Miroslav, you did not install the correct rom : it must end with 134 numbers, not 124.

You can use filezilla (or another FTP client) to download it, at the official FTP server ( check the GUIDE : everything you need to know).
[YotaPhone] Miroslav1999:
I used 5.0.0-HK1.1.66 first and did the OTA update on it, about 200 MB. Then I installed 5.0.0-RU1.1.124 from the link in the instrucions as well. If you know the link for the 134, please let me know! Thank you in forward!

i'm sorry.....now I think this is the right file, don't think there is a newer version. Anyone else to help Miroslav ? :(
[YotaPhone] Tippfehler:
Maybe the yotaflasher folder is write protected and in the folder is still the HK-ROM.
[YotaPhone] Miroslav1999:
I run Yotaflasher from the default Program files (x86) folder, and within there I created that "firmware" as instructions say, where I deleted previous HK files and paster RU files.... will try again perhaps.

Also did anyone notice that EPD doesn't work well when trying to send sms... i keep pressing letters, but nothing is getting typed, then I press lock/unlock and then it starts to respond, and then the "Send" button doesn't work, and I have to press "lock/unlock" for it to work again....
[YotaPhone] JavaDroid_:
work fine here
[YotaPhone] Miroslav1999:
I re-flashed it again with the latest RU files, and this time it worked, not sure what happened before and why it kept HK file version.... the latest RU build works much better and many former bugs have been fixed! Thank you for the good work!

[YotaPhone] Parmo100:
1. normally you buy a yd206 phone that has a retailer CN or HK ROM. You are unable to do an OTA from this ROM. So to update the firmware , you use yotaflasher to flash whichever official ROM version you want, so yes you can flash an official CN version if you want, but most people here are not Chinese so they flash RU or EU ROM.

What most people here have done is flash the RU ROM .

2. You can flash the RU lollipop directly or the last RU KitKat ROM. Then use OTA to get to the latest version. You only need to make 1 flash in all cases followed by OTA to get to latest version .

So if you want the HK version, make 1 flash to official HK. Only 1.

3. Use yotaflasher to download target ROM but replace the downloaded radio directory with the CN or HK radio directory. This can be problematic, this is a moderately difficult technical task, you can brick your new phone . If you live in Asia (and most of Europe) updating radio is not necessary. This is all described in document mentioned in above post.

[YotaPhone] Parmo100:
You can see all the versions in yotaflasher EXCEPT the OTA update. I only know RU and EU , when I flashed to RU 124 and did the OTA to get RU 134 , the RU was the only 134 version. In general RU will always get the latest version first and will be supported the longest. Best if you look at yotaflasher yourself to see all the possible versions for your choice of ROM.
[YotaPhone] M. Baqir:
Last thing for the confirmation bro

Are the steps as follows? I have CN yd206

1. Flash latest CN

2. Update to L when OTA update comes

3. Download and flash RU

4. Update when RU lollipop update comes

Now i am in .134 RU at yd201 from CN kitkat at yd206

Secondly

YP2 hardware according to gsmarena aupports 3G bandsHSDPA 850 / 900 / 1900 / 21004G bandsLTE band 3(1800), 7(2600), 20(800). I saw that Russia does not use LTE band that is used here in my country Pakistan LTE Band3 1800MHz. So if i flash RU means i will not be able to use LTE here. Is it so?

Thanks for the patience
[YotaPhone] Parmo100:
You only need to do 1 flash direct from your new phone and then do OTA. ONLY 1 FLASH.

1. Download yotaflasher (on PC/laptop)

2. Download RU ROM with yotaflasher

3. Flash the RU ROM with yotaflasher

4. OTA to get latest 134 RU version (on yotaphone)

After the RU flash it will say you have yd201 but your hardware is really a yd206 still with Chinese LTE bands. I am sure your phone will work after this flash without changing the radio . I don't recommend you change the radio (LTE band) , just download RU ROM and flash it. There will be at least 1 overlapping LTE band between China and your country.

If you have problems flashing, please read the above guide.
[YotaPhone] M. Baqir:
So nice of you bro. Now it is really crystal clear for me. Yes, China, Hong Kong and Pakistan have LTE Band 3 1800MHZ as overlapping, So I do not need to change Radio. So so so nice of you. stay blessed. This is amazing community with amazing and friendly members who guide promptly, patiently and sincerely.

Just read through this thread.. I'm having the same problem as some others did.. I made it successfully through step 7 and ended up finally with build # LRX21M.5.0.0-HK1.1.124d .

Next>>

I deleted the HK firmware files from the firmware folder and downloaded the 5.0.0-RU1.1.124.zip and extracted to the firmware folder of yotaflasher.

This time when I run the flasher it runs through the files too fast.. I don't see any errors either but it's too quick to have installed the firmware.. the phone reboots and I'm still with hk1.1.124d . I tried it several times with the same result.

Anyone else have this issue.. any workarounds? I'd like to get the RU 1.1.134 version to automatically receive the OTA updates

For anyone else that runs into the same problem try a different computer.

For some unknown reason on my desktop pc I was able to update my firmware once from kitkat 4.4.3 to the hk1.1.124b lollipop.. but had problems right after that doing everything correctly to the 'T' .

Try ignoring the instructions about downloading HK ROM, just download the RU ROM then flash it with yotaflasher. You also don't have to unpack anything. Just use the yotaflasher. In nearly all cases, the HK/CN radio directory does not need to be updated. This makes things much much easier for newbies.
