STILL IN THE BOOT ANIMATION "POWERED BY ANDROID" for the PAST 1 HOUR

Can we directly flash from HK kitkat to RU lolipop without flashing into HK lolipop?

How much time it will take after flashing to boot up to the home screen?

Shall we detach the usb cable just after closing the yota flasher prompt or shall we keep the mobile attached to the computer until it boots up to the home screen and then detach from the computer?

Kindly answer my questions... its a new piece i bought 3 days ago... I got stuck in the boot animation:(:crying::(:crying::(:crying:

Phone frozen on "Powered on Android" start up screen. PLS help

So I bought a Yotaphone 2 (YD206) and after reading several threads on how to upgrade it I decided to give it a try as it seemed pretty straight forward even for me who know very little about computers and especially PCs as I am an MAC user.

I tried to put 5.0.0-EU1.124b.zip on the phone. I used a pretty beaten up PC running Win 10. Now my phone is stuck on powered on Android start up screen after a couple attempts. I know I made a mistake right in the start as I did not put my Yota in "developer mode and enable debugging mode" (this was not mention in a few other threads). So I figured that this might be my problem. But as I am stuck in splash screen, how do I "factory reset" it back to the HK1.0.3.61.a version it came with? Holding power + vol down and choosing option factory reset does not work.

In Android system recovery it says:

LRX21M.5.0.0-EU1.1.124b

When wiping cache or data/factory reset it says E:Cannot load volume /misc!
[YotaPhone] binu2389:
Same for me bro:(:crying::(:crying::(:crying:

Dont know what to do now... I tried all the ways i can but stil... :crying::crying:

Somebody please help us...
[YotaPhone] Ogge666:
So I managed to get mine started. I deleted yotaflasher folder. Re installed the Qualcomm drivers, restarted the (old) PC which had a massive windows update. Re installed yotaflasher and downloaded my old firmware (HK1.0.3.61.a), unpacked it to "firmware" folder in the yotaflasher folder put the phone in downloading mode by power button + volume up, and flashed it to phone. The phone started and it gave me the option to update to Android 5.0 with build nr 5.0.0-HK1.1.24d. Most is working OK now, but the E-ink screen is behaving completely weird and does not seem to react all the time... When I change the page its like it is refreshing from right to left of screen with a white band moving across..? Anyone experiencing anything like this? Is there any chance to make this go away from installing the EU 5.0 version?
[YotaPhone] binu2389:
Bro... I successfully updated the RU version... All went smoothly...

What i did was... I entered the recovery mode by pressing the power button followed by the volume + up button. And deleted the cache partition and the dev partition too... after this i just put the mobile into power off mode from the same screen. And kept it idle for some time like half an hour or 1 hour. and i restarted my PC too.

After this, i did our normal procedure as usual. Copied the firmware folder containing RU version to yota flasher as normal. Then i tried... and it worked bro...:victory::victory::victory::good::good::good:

Got an update also after the Installation completes as said in the article. Now running RU 1.134 successfully:victory::victory::victory::good::good::good:

Hello all. I received my YD-206 one week ago, sporting a HK KitKat version. So far everything seems really nice and I have not spotted any problem at all. Seeing problems several have detected with radio (seems related to using the proper radio instead RU or EU ones) and the problem with the EPD (for me it is quite important) I am not sure if the upgrade to Lollipop is mandatory.

Could you please xplain benefits to go to 5.0? Performance? Battery duration? Also, of those who have migrated the yd-206 to 5.0, any problem?

Thanks!!!
[YotaPhone] sekall12:
My first feedback after 3 weeks with a YD206 (gearbest.com) reflashed to RU (1.1.134) without additional tweaks:

Well as for the performance: I used stock chinese 4.4.3 for a day. It was OK but it didn't feel that smooth to me.

3 weeks ago I flashed to RU 1.1.124 (yotaflasher) and OTA updated to RU 1.1.134. I was baffled by the performance. I came from a Galaxy S4 with a very fast ROM but the yotaphone with 5.0 is way smoother and faster in every way with every App now. I felt that original yotaphone CN 4.4.3 was not thaaat smooth...

EPD works great for me (and it got some improvement in 5.0 as far as I know).

Now for the disadvantages [solved!! see below]:

- WiFi and bluetooth don't like each other. I need to deactivate bluetooth manually to get full WiFi speed (otherwise just 20 kb/s)

- since deactivating bluetooth most of the time I feel like having WAY better battery life especially in idle

- "NFC Agent"-app drained alot of my battery: I don't use it -> deactivated it, as well as NFC

[ EDIT: solved] Do a factory reset after flashing!! I remembered that I had a 6 hour "preparing apps" screen after flashing. It wouldn't end, so i forced a reboot. Now after factory reset everything is fine and even better battery life in idle. I love this phone right now.

I think that is a feature. You can choose animations when changing / scrolling EPD screens.
[YotaPhone] Ogge666:
Yes, I figured this out, but thanks! If I would not have figured it out it would have been driving me crazy!

A few question.

As mentioned before I ended up with the HK version 1.1.124d.

My phone seems to be working better and better. I don´t know if I would get any better better experience flashing it to RU or EU? Any ideas??

I read in a earlier post that a few users had problems with charging, today I had the same problem. I left the Yota for charge overnight and it had not charged in the morning, all I had to do was to restart the phone and it would immediately start to charge. anyone figured this problem out??

Guide update

Sorry for my English, as it is an edited translation of Google.

It is necessary to make adjustments to instruction, which is set out at the beginning of the topic.

YD206 and YD201 have different radios. For the correct and stable operation of your phone in GSM networks (and possibly in other cases) the Chinese version of the radio module firmware is required. RU, EU, HK versions contain Russian version of the radio module firmware. I did not compare the possibilities of different versions, the choice is yours.

You need to download Yotaflasher, the selected firmware version and Chinese firmware 4.4.3-S01-003-CN1.0.3.32a. Be sure to check the integrity of downloaded files (eg, by 7-zip). The phone must be fully charged.

1) Install Yotaflasher.

2) In the folder, where you installed Yotaflasher, create a new folder and name it firmware.

3) From the Chinese firmware file 4.4.3-S01-003-CN1.0.3.32a.zip unzip the folder Radio to the folder firmware.

4) From the archives to the chosen version of the firmware unzip to the folder firmware all the files except the Radio folder.

5) Turn off Yotaphone 2. Hold down Vol - button, press the power button. "Downloading ..." in small font will appear on the screen.

6) Run Yotaflasher, select 1. You will see "waiting device". Close absolutely all the programs that you can close, including running in the background. This will avoid problems during flashing that are caused by lack of memory.

7) Connect your phone to your computer. If ADB driver has been installed, the process of flashing will start. If not, a message appears that the driver is not found for the device. Open the Device Manager. There will be an Android device with a yellow exclamation mark next to. Right click on it and select Update Driver -> Search for driver on my computer. Select the folder in which you installed Yotaflasher, select the "Search subfolders", click "Next". ADB driver will be installed and flashing will start. Close Device Manager.

8) In the course of the flashing you will be prompted to delete the user data. Select "y".

9) After the flashing phone will reboot. Unplug it from the computer. In Yotaflasher window select 3.

10) The first launch can be lengthy. Don't worry.

11) Update your phone to the latest firmware version via OTA.
[YotaPhone] hmedevil:
[MENTION=7909062]knk.ua[/MENTION] are you sure that Hk version also has Russian radio module (yd201??). The current one I have is a YD206 purchased on Aliexpress, with firmware HK1.0.3.61a and baseband S01_003_3034_CN1_M05....so far working OK but in KK 4.4.3...

I have seen this recommendation you suggest in other posts. Any one can verify problems if not using that radio FW?

Thanks!
[YotaPhone] knk.ua:
Chinese vendors are doing what I described apparently. The name of the device is changed in build.prop. The original firmware HK1.0.3.61a from Yotadevice ftp server is designed for YD201 and contains Russian radio. I checked. I can not post a screenshot, as already set up my phone and it is a pity to waste time again.
[YotaPhone] hmedevil:
Thanks [MENTION=7909062]knk.ua[/MENTION] , just wanted to confirmar that. Si, changing radio module, It seems worth to go to Lollipop. Any other can confirm or report his/her experience?

Yes. This process has no difference for EU version. Everything is very simple. To do something wrong is almost impossible.

How did you go back from RU to HK?

I also wanted to downgrade, but the method I tried wasn't successful
[YotaPhone] bionicbee2000:
Maybe not helpful but thanks. Worked like a charm. Got my 206 today. Yotaflasher and the adb stuff installed. Extracted the RU-Version into the folder and started the upgrade.

Was through in about 10 min. Even my initial user settings were restored. Autoupdate for the correct ADB driver was also included.

Thanks again. Now I need root and then Linux :)

I tried installing the RU firmware and I am getting an error message saying "Cannot load firmware/system.img", but I checked the folder and the file is present. Any ideas why this is happening?
[YotaPhone] sekall12:
I have a YD206 and directly rushed to 1.1.124 without special treatment. I'm using vodafone and my radio works great. I even have better qualits / signal than with my galaxy S4.

Do it all again from the start. Maybe even on a different PC. Sometimes there are tiny mistakes that mess up everything.

Someone here wrote her had problems with winRAR not unpacking properly.
[YotaPhone] ttttmax:
Thank you so very much. You sir are a genius. I took the biggest gamble ever I used VirtualBox on a Mac to do the upgrade. As crazy as that sounds it worked like a Charm. The anxiety I felt during the Boot animation. :laugh:
[YotaPhone] jjt2mey:
Yes, and successfully.

I got this error when installing yotaphone2_flasher:

"The program can't start because MSVCR100.dll is missing from your computer. Try reinstalling the program to fix this problem."​

Re-installing didn't fix the problem, so I found this thread:

http://xdaforums.com/lg-g3/general/guide-root-lg-firmwares-kitkat-lollipop-t3056951

which said

"If you got "MSVCR100.dll is missing" error, install Visual C++ Redistributable.

(64 bit users, also install this file and not the 64bit version)"​

Even though I have Windows 10 64-bit, I followed those instructions and installed the linked x86 Visual C++ Redistributable, and not the 64-bit one.

Re-ran yotaphone2_flasher and exited ("3"). This worked, and I have successfully gone through the OP's steps and installed the HK firmware (with the CN radio per knk.ua's post #36 on page 4). Will probably install the RU firmware, just a little scared from other posts that the EPD screen might be negatively affected.
[YotaPhone] knk.ua:
This topic discusses "In what order to do the firmware?" or "Is it possible to flash after flashing A firmware B?" It does not matter. Partitions are erased completely by the flashing process and are wrote by new from the new firmware.

And do not use WinRAR for unzipping firmware. There is 7-zip which allows you to check the integrity of the downloaded archive. This should definitely be done before flashing.
[YotaPhone] Jube91:
Edit.

I updated it like in the guide and then tried to put the RU version, but after flashing it with the RU version, I didnt received any OTA and the kernel is like the HK version :S

I got my Chinese version YD206. As I do not have access to a PC right now, is there anyway I can do this through mobile itself?
[YotaPhone] Parmo100:
All the (unsigned) ROMs are available at ftp://fw.ydevices.com/YotaPhone2/Firmwares/

The fastboot flashing commands are on here somewhere.

However This is only for very experienced flashers

But the answer to your question is "yes"

---------- Post added at 02:18 AM ---------- Previous post was at 02:02 AM ----------

Best to look into settings to see what version you have, go to "about phone" at bottom of settings, then look at "build number" again right at the bottom. If there is a "HK" in the build (which I suspect) then you are still using same firmware, nothing was flashed.

Did you notice any error messages during the flashing, the most obvious one is "device not found" which means you haven't got the necessary drivers on your windows machine to communicate with your Yotaphone. Have you also set developer mode and "allow debugging" on your Yotaphone?
[YotaPhone] virtuanemo:
The answer is NO. You need YotaFlasher and PC to do it since YD206 is based on 4.4.4
[YotaPhone] A2X:
Hello folks,

I successfully flashed the HK ROM and updated it to the latest version via OTA. Unfortunately the RU ROM won't flash. No matter how often I try the phone info says it still hast the HK ROM flashed.

I did enable the usb debugging mode and I even cleared the cache partition. The flashing process via the yota flasher is way faster when flashing the RU ROM than it was when I flashed the HK ROM. The boot screen loop takes some time though.

I also tried to download the RU rom again, still won't flash.

Any Ideas?

How long did it take after flashing till boot? Mine is stuck at 'powered by android' for about an hour. I flashed the RU version and followed the steps as given.
[YotaPhone] bharathreddyt:
Ok, so here's what I did.

1. I tried the RU version 5.0.0-RU1.1.124.

Flashing it was too quick to believe. And that failed at the 'Powered by android' after reboot.

Tried the recovery mode - Power + vol up. Cleared the user data and cache. Rebooted. Still stuck at the 'Powered by android' message.

2. So this time I cleared the cache and user data again and flashed 5.0.0-APC.1.65 (I live in India currently btw).

Flashing took some time, about a minute, and then asked to clear user data. did that.

Reboot went to the splash screen this time. Stayed on the splash screen for about 15 minutes and then asked me to setup Android 5.

And btw, like others said, I did not get an OTA update after I was online. When I checked for updates, it said I already have the latest. The build is LRX21M.5.0.0-APC.1.65.

So that's it, all is well.

Has anyone used the APC version? Any issues? The only one I found was that the back screen doesn't unlock when I swipe up on its unlock icon. I've to use the power button to wake it up. It's probably just me, I've barely had this phone for 3 days.

Cheers to the initiator of this post!! :good:
[YotaPhone] Parmo100:
I've never used Asia Pacific ROM. The best updated ROMs are 1. RU and next best 2. EU.

I guess there is no OTA for your lollipop APC.

The fact that your first attempt at flashing to RU failed is worrying, but others have had the same problem. Read up on xda here. It's something to do with lack of memory and diskspace on your PC/laptop I think.

BUT I always try to do things the easiest way, I first flashed from original retailer Kitkat 4.4.3 HK ROM to last RU KitKat ROM, and then did an OTA. This method is safer and still involves only 1 flash and 1 OTA. There is a long 5 plus minute wait at Yotaphone splash screen video.
[YotaPhone] L.Batista:
How long did take to first boot loolipop using method?

How long did it take to boot after the RU Android 5.0 134 OTA update using this method? Was there any problem? I mean.... How long did take to first boot loolipop using this method? Thanks
[YotaPhone] Parmo100:
During the OTA, all apps must be converted from kitkat to lollipop, so the answer is depends on how many apps you have. The blue yotaphone video will play for 5-10 minutes plus during this conversion. Must be patient!
[YotaPhone] L.Batista:
Pin this other method

Since many people have had problems with the first's page method I think it would be better to pin this other one on the first page. Besides it seems pretty simpler than the first. Also It would be amazing if one make a video showing it on youtube. There's nothing there explaning the process. And lots of people are interested in knowing that, at least here in Brazil I think so.:D

I didn't try yet. Mine is still coming.

GSM signal lost after upgrade from HK to RU firmware

Hi!

I have made the upgrade using this method, but now the phone only works with WCDMA network and above. I live in Portugal and most of the time it only exists GSM signal. Have anyone experienced this problem? What can i do to solve this problem? I have reinstaled the firmware but it still the same. Can anyone help me?

Thanks
[YotaPhone] Parmo100:
You now have a yd206 handset flashed to be like a yd201, i.e a phone configured to use HK/Chinese LTE bands but on a Portuguese network that uses different LTE bands. But for most countries, at least one of the yd206 LTE bands usually DOES work, there is an overlap of LTE bands, mine included. In your case there are no overlapping LTE bands. Maybe you can test this with another SIM from your country and check LTE band compatability on Internet.

If they are not compatible, You have to now flash the "radio" from your original firmware (HK) into the RU or EU firmware. The method is on xda here.
[YotaPhone] L.Batista:
Can Flash twice with Yotaflasher?

Do you think I can flash to RU 1.1.124 using Yotaflasher again after flashing from HK1.0.3.61a to RU1.0.3.61a? Or could that lead to any problem?

I ask that because the update from RU1.0.3.61a kitkat to RU 1.1.134 loolipop is about 1GB. So I could take a nice shortcut if use Yotaflasher twice, you know. And it seems that some guys have had problems to make the update of such a big file via OTA.

Any thoughts on it? Please, waiting for answer. Thanks.
[YotaPhone] TheArt.:
Sure you can flash directly 124 starting from your initial firmware and then by OTA of 189MB go to 134 RU. Many people flashed like this and didn't have problems. (Change the radio accordingly).

The fact is that the system.img file of 124 is big for some old PCs or these PCs can't handle it well. Hence it's suggested to flash 4.4.3 which is less heavy. If you properly installed the drivers&yotaflasher you can do it! If it gives ERROR try to flash system by 512 steps, you will find here on xda the right fastboot command.

Hello,

I've got a YD206 (HK) and the 1&1-SIM (vodafone.de, 3G, 900/1800/2100) does not work (sim not found). I have upgraded to Android 5 and 6 (YD201), no difference. My provider gave me a new SIM and it is working now, but the signal is very weak (mostly no signal). I have tried RU-Radio-ROM, EU-Radio-ROM and HK-Radio-ROM without any difference. Is there a known problem with gsm900?

Do I need a special Radio-ROM for vodafone.de (3G)?

Frequencies in Germany:

If I insert a Netzclub-SIM (E-Plus, 1800/2100), the signal is good.

You need CN radio, in fact every YD206 need a CN radio to maximum signal.
[YotaPhone] Tippfehler:
Many thanks, I thought HK-Radio and CN-Radio are similar. With CN-Radio, the YD206 has a strong signal now.
[YotaPhone] TheArt.:
Exactly, the only concern with a RU firmware and CN radio is that the promixity sensor stay always active (go in a dark room and look on the left of front camera). I still don't know how to solve it, because some people on 4pda reported that their YD206 with this configuration doesn't blink. :confused:

What do you mean?

Does it mean that even for people who doesnt have problem with poor signal can achieve better quality by using CN radio? Do I need it in Brazil?:confused:
