Sure it is:

fastboot flash modem <firmware-folder>\radio\NON-HLOS.bin

fastboot flash sbl1 <firmware-folder>\radio\sbl1.mbn

fastboot flash rpm <firmware-folder>\radio\rpm.mbn

fastboot flash tz <firmware-folder>\radio\tz.mbn

<firmware-folder> - specify full path to folder with firmware that contains radio version you'd like to flash

Be careful to specify modem/sbl1/rpm/tz after 'fastboot flash' command.

On the note of flashing different versions to use the phone in different areas, I'm just wondered if anyone here has purchased a 206 from China/HK and tried to use it in the UK? I have received my device today and tried to use it but cannot pick up any network reception at all - wifi seems to work fine.. The SIM card I'm using works fine in my Sony Z3 so I know that's not the issue.

I've tried to flash several different software versions with all kinds of radio combinations but nothing seems to be working.. Maybe I have dodgy hardware or maybe there's something I've missed?

As I understand it, EE use;

800MHz(band 20) for 4G

1800MHz(band 3) for 2G and 4G

2100MHz(band 1) for 3G only

2600MHz(band 7) for 4G
[YotaPhone] borekon:
does it works on 800 mhz LTE?
[YotaPhone] Szilvio84:
Nope..I've tried that way and it doesn't get LTE bandwidth only H+.. (Germany, Provider: 1&1 )

Any other idea maybe?

Greetings
[YotaPhone] kbal:
206 flashed to 201 has no LTE (LTE 800 band 20). H+ is max.

I don't think it's even possible to unlock band 20 on Snapdragon 801.

Mine is working on LTE (the lte label appears on the signal strength). But don't know if it is in 800, 1600 or 2100 Mhz.

LTE Issue

Hi

can you please tell then which from type of FW your Radio folder been flashed?

do you have an yd201 or yd206?

in which country do you have the LTE? EU?

Thanks
[YotaPhone] borekon:
My fault, i only read the specs and not looked into the phone. It's snapdragon 801

I have yd206 and tried that: http://xdaforums.com/showpost.php?p=69408327&postcount=61

The country is Spain, but all the LTE(FDD) frecuencies are supposed to be the same in all EU contries.
[YotaPhone] Szilvio84:
hm..so you also took the 4.4.3-S01-003-CN1.0.3.32a.zip FW..

did you flashed only the Radio folder via fastboot commands?

or did you changed the folders rezipped the data to 5.0.0-EU1.1.124b.zip and then used yotaphone_flasher?

thanks
[YotaPhone] borekon:
The exactly steps described before. Just changed the folders. I didn't zipped nor unzipped anything.

pkease help me. I have a yd 201. The update failed and the phone openwith the logo android. I have trued yp flasher and it is the same problem. Unkknow chunk type.
[YotaPhone] VirtuaLeech:
It's a common problem. Try this:

- Put your phone in download mode. Just keep holding power and volume down, it will get there eventually.

- Use the YotaFlash tool to flash the latest EU or RU firmware, whichever you like.

- After YotaFlash is finished your phone will reboot and still be in a bootloop

- Put your phone in download mode again. Just keep holding power and volume down.

- Now go into the command prompt on your computer and navigate to the YotaFlash folder (for me it is in C:\Program Files (x86)\yotaphone_flasher)

- Now type the following command with your phone still in download mode: fastboot flash -S 512M system firmware/system.img This will flash the failed system.img in multiple parts.

- After the flashing of the system partition is finished reboot your phone with the command: fastboot reboot

After this your phone will restart. It may take around 10 minutes to finish and if everything went right the Android unlock screen should appear.

[YotaPhone] Parmo100:
Maristrat, normally yotaflasher has no problems with basic flashing. Is your flashing complex ? Did you copy new radio folder maybe from Chinese radio yd206 to Europe yd201 ? I had chunk error when I tried that . Just clear everything , download again yotaflasher and try to find out if simple flashing is working.

If you don't copy the radio folder , is there still the same problem of chunksize error ?

If nothing is working, maybe you can try flashing back to the earliest KitKat ROM for Europe ? Or even Hong Kong KitKat (depending on your original ROM). Just to test if basic flashing is working at all .

If simple flashing is working, then you can try flashing your chosen zip file then fastbooting radio files 1 by 1 as described in post above.

What I did was to flash first to a newer KitKat version and then update to lollipop by OTA. But I bought a yd206.
[YotaPhone] Maristrat:

[YotaPhone] Parmo100:
If you bought your Yotaphone from China or HK, the initial firmware has been modified by the retailer, usually you cannot do an OTA. You say that you did an OTA and Then tries flashing? But I only know yd206. If you used the standard yotaflasher without changing radio directory, there are usually no problems. The only known error is the chunk size that virtuall leech mentioned, caused by not enough disk space or memory.

How to install these drivers?

Hi, can you please explain to a complete idiot how to install these drivers?

I'm trying to go the yotaphoneflasher route from a CN 206 to a RU 201 if that makes sense...

My PC is an ancient 386 so I assume that I should install the files in the i386 folder in /yotaphone_flasher/Driver/Google/i386

But I dont comprehend how this is done...

So far the flasher is prompting <waiting for device> and phone is showing "downloading..." but plugging in the USB cable has no effect.

I manually downloaded the 4.4.3-S01-003-RU1.0.3.61a.zip, should I place this in the /yotaphone_flasher folder or where?

Also I read on these forums that keeping the 206 Radio folder files will be better, would it make sense to replace the Radio folder within the 4.4.3-S01-003-RU1.0.3.61a.zip with the Radio folder contents from the 4.4.3-S01-003-CN1.0.3.32a.zip and then flash the modified zip?

Thanks in advance for any time you can spare for this advice!
[YotaPhone] VirtuaLeech:
You can install the drivers by going to the \yotaphone_flasher\Driver\Google folder and rightclick on the INF file and then choose install. This is a silent install so nothing will be visible on screen. You don't have to download the zip yourself, this is done by the yota flasher when you choose which firmware you want. If you want to have the original Chinese radio then you have to abort the yota flasher after it has downloaded the firmware you want and then replace the radio folder with de desired one. After that restart yota flasher.
[YotaPhone] nutsoboy:
Since I already manually downloaded the zip, where in the yotaflasher directory structure should I place it for the software to load it correctly?
[YotaPhone] nutsoboy:
I followed these instructions to install the drivers but I’m still stuck with waiting/downloading...

How/where can I check if the drivers are installed??
[YotaPhone] nutsoboy:
To update my situation I have checked by following instructions on other threads here and the drivers included with yotaphone_flasher are simply not installing. I also tried installing ADB and fastboot and they also fail to install on my old PC running Windows XP SP3.

So it seems I will never get yotaphone_flasher to connect with the phone. After days of frustration I need to choose between continuing my quest TOWARDS MADNESS or giving up and throwing the phone AND the PC out the window.

1 Can anyone with infinite patience advise if there is a way to manually install these #+@&_)?× drivers???

Thanks in advance!
[YotaPhone] VirtuaLeech:
You can try to install the universal ADB drivers. This seems to work for some people on the forum. They can be found here http://adbdriver.com/
[YotaPhone] nutsoboy:
Thanks I already attempted to run this installer and get [Error] Device not found

In the APK Installer window nothing is listed under Manufacturer/Description etc. Should there be?

Do I need to have the phone plugged in to install?

"Help" is clear as mud, the screenshots show some newer OS, mine is XP SP3 [x86]

Where do I find Troubleshoot/Advanced Options/Startup Settings to disable driver signature enforcement?

Any help appreciated!
[YotaPhone] Electropherogram:
One thing that helped me when flashing my Yota was disconnecting the computer from internet before connecting it to the phone. That's because as soon as the Yota was plugged, wrong drivers started to download and install automaticly, causing problems. In the end I had a correct connection with the Google driver according to the device manager. I added the driver by "adding a legacy hardware".

How do you have killed the phone? I have the same problem, but I can not any more activate the download mode :(
[YotaPhone] 10basetom:
Hi guys, sorry for this silly question, but where exactly does yotaphone_flasher download the firmware? I have downloaded the latest RU firmware (but have not flashed yet) and the screen reads "Your current firmware is: 5.0.0-RU1.1.124.zip", but for the life of me I cannot find 5.0.0-RU1.1.124.zip anywhere on my PC or the phone. The reason I don't want to flash right now is because I want to replace the RADIO folder with the one from the latest CN firmware, but right now I can't even locate the firmware folder.

Do I need to root the YP2 and install Root Explorer to find the zip?

UPDATE: Never mind, I can see the firmware folder now -- I had to use WS_FTP. Does anyone know why Windows 10 cannot see this folder? Very strange...

UPDATE 2: After downloading the CN firmware from the FTP server to the yotaphone_flasher folder, I realized that I also cannot see the zip I just downloaded. Only after moving the zip outside the yotaphone_flasher folder was I finally able to see it! Very strange indeed.
[YotaPhone] VirtuaLeech:
Keep holding Volume Down and power. It may take two or three reboots but most of the time it will go into download mode eventually.
[YotaPhone] victro:
The "yotaphone_flasher" downloading firmware zip and decompressed it to the "firmware" folder in self root folder (C:\Program Files (x86)\yotaphone_flasher). You wont see zip file, it deleted by programs itself.

Hi,

did you ever tried to connect your phone to a different USB port? Sometimes the drivers are going corrupt during the installation and then you phone can't be recognized on this port, but it works on port 2, port 3 and so on. Sometimes it helps to connect a USB Hub to this USB port and then connect the device to the hub.

With a USBDeview tool you can monitor your USB ports, see when a device is going connected and disable or remove faulty ones.

As a junior member I can't paste a link for this tool but you can google for it.

Here are a few things to know.

Factory delivered YD206 version came with custom software HK 4.4.3. and CN Radio where no system update is available.

This combination is best with CN radio because it has best signal, and EDGE is wotking in CN Radio. I think all oder Radio versions have no EDGE, and bad Signal.

There is no problem flashing YD206 to 5.0 with yotaflasher and the officially packaged od Yota FTP. But once you have flashed YD206 to YD201 5.0 then this was it.

You wont be able to gat back to the YD206 version. Once you have Android 5.0. you wont be able to flash again on 5.0.

You have to Flash 4.4.3 with radio pack as you wish, then software update is available. But since the phone will automaticly update to andoid 5.0 your CN radio signal will get lost and be replaced with RU radio with no edge !

I tried to flash every version available on Yota FTP. No matter which 4.4

Android 5.0. on Yota is superiour, but signal is bad because no CN radio.

---------- Post added at 09:12 AM ---------- Previous post was at 09:11 AM ----------

IS it possible to flash just Radio afterwards on the yotaphone ?

I get all 2g, 3g, 4g with good signal.

For 2g, only band 1800mhz is available.

So if ur provider use 900mhz, so bad news.

For flashing radio only.

- download firmware

- copy radio folder to related folder

- enable developer mode

- turn off phone

- press vol down and power button, both

- now "downloading" mode

- plug in usb to pc (make sure all driver are properly install)

- do fastboot

fastboot flash modem d:\NON-HLOS.bin

fastboot flash sbl1 d:\sbl1.mbn

fastboot flash rpm d:\rpm.mbn

fastboot flash tz d:\tz.mbn

Fastboot reboot

Do mind that drive "d:" above just example. Only you know where you place it.

Already knew this. Actually, the yd206 specs says that the phone works on LTE B1 (2100) and LTE B3 (1800). Where it doesn't work is in the LTE B20 (800). The yd201 works on LTE B20 (better signal strength than B3). Source
[YotaPhone] cvzalez:
Better signal IS NOT faster speed.

True, but while 800MHz has better signal for long distances also it has less data speed than higher frequency, also truth that it uses less battery, this is truth for all the radio signals. For the same frequency LTE uses more battery LTE>UMTS>GSM, so if you don't need the speed LTE>UMTS>GSM, UMTS can be a good balance, also depends of what kind of Phone Towers you have near your location.

Vodafone Portugal uses this:

GSM: 900MHz / 1800MHz

UMTS: 900MHz / 2100MHz

LTE: 800MHz / 1800MHz / 2600MHz
[YotaPhone] borekon:
Good to know. Portugal and Spain uses the same LTE frequencies ;)

Hello, thanks for all your replies.

I have just bought a YD206 after having owned a YD201 for over 1,5 year.

My YD201 does not have a working front screen anymore, so I do everything with the backscreen. For me this is a blessing in disguise, as I really grown in enjoying the comfort of the EPD screen for my eyes and the tactile joy of swiping the backscreen.

As for updating: am I right with the understanding that it seems the easiest to flash 4.3 and update from there? From reading most of the thread, that is what looks like the easiest, most reliable option to me. It would be great if someone can let me in on this.

Best, Tom
[YotaPhone] Parmo100:
I recommend that method, it is the safest NOT the easiest. You will have a monster 1GB OTA after the flash and you will have a 5-10 minute wait for OTA to install correctly. But I think that is the safest way, yes. Only EPD? Great, you will save lots of battery too
