I can try to send you my qcn... But my phone has no phone service... I don't have the original qcn... Lost qcn only the flashed qcn. I have IMEI s but no network connection.
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] hanguyen1589:
You can see imei with * # 06 # if there is still information of MEID, if not, we must ask for a QCN file from a good machine to handle this job.
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] gadfly:
Hello to everyone and thanks for the support . have flashed to Yota3+, looks great, have IMEIs and listed baseband but no network , no choice of perferred service. Have the feeling i have no radio.img on the phone. does anyone know how I can check RADIO and possibly replace it ?

THANKS
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] hanguyen1589:
Can you help me backup your QCN file so I can try to restore imei on my device? If possible, please send me an email: hanguyen1589@gmail.com help me, thank you very much
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] hanguyen1589:
Thanks so much for helping me back up the .QCN file. Currently my device has received sim but no waves, it said: no service.
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] HvMES:
Hi Can you store the QCN file on a google drive so I can use this as well to restore my empty IMEI originals?

Thanks
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] gadfly:
Did you have service BEFORE restoring the qcn file? I always had IMEIs and recognition of my SIM cards but never service after flashing 3+. What can we do? Flash the radio? How?
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] hanguyen1589:
Sorry it is not mine so I can't share it for everyone, you can ask [MENTION=701145]gadfly[/MENTION], if he agrees I will transfer it to google drive for everyone immediately. As for the case of my device, I transferred to the manufacturer to be supported to record imei, according to the store information, about 1 month later I will be able to receive the device again.
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] gadfly:
sure if it helps anyone please share. But I believe this qcn is after the flash. You don’t have network nor do I. I hope we can get this figured out. Who has flashed their Chinese roms and HAVE network service?
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] hanguyen1589:
This is the QCN file of [MENTION=701145]gadfly[/MENTION], can you try it or not? I will upload my QCN as soon as I receive the machine from the manufacturer

[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] gadfly:
Any luck getting you SIMs to work? Did you get your IMEIs set? I have always had my IMEIs and SIM cards recognized, but no service, in *#*#4636#*#* can not select radio service band or keep radio power turned on.

My first flash attempt I feel I inadvertently activated something in TWRP from the back screen. Despite multiple flashing, while system seems in every other way perfect, I have no mobile service. The sellers of the yota3+ in China only offer the the 128GB international model. I bought the Chinese 64GB model. Had anyone with the 64GB model successfully flashed yota3+. Any idea how to fix my noobile service problem? THANKS.
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] gadfly:
One step forward two steps back. I flashed the NON-HLOS.bin from the stock ROM and I have mobile service!!!!!! Yeah! BUT NOW ...... E-Ink screen is locked... unusable ... can open apps front the front screen (chess, sodoku) they open on the E-Ink but screen is frozen. Also, the fingerprint scanner is wanky. Any ideas? Any one have a yota3+ NON-HLOS.bin they can send me?

thanks
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] simonkin:
Hi gadfly, I have exactly same issue, flash my 64g yota3 to 3+ with no issue, everything fine only SIM card not work but reconginized, can not voice call or use mobile data. And when I flash back to yota3 CN rom, everything fine with same SIM card.

I found there are only 2 base band version, ‘8953_GEN_PACK-1.102097.1.104384’ for yota 3 CN, ‘TA.2.3.c1-00684-8953_GEN_PACK-1’ for yota 3+ HK version. I try to flash CN baseband (non-Hilo’s.bin) together with 3+ system, it show signal when insert a SIM card, but soon system hang and doesn’t work; and when try to flash 3+ baseband with yota3 CN system, the baseband version show unknown, totally not work.

Suspect the reason maybe:

1. there are some limitation in HK version, on band frequency? Network operator?

2. Still bug in 0112 image? I noticed not all file are flashed, based on the content in rawprogram0.xml, but need to be very careful because my understand is some file may damage the phone.

One more thing, I’m in Singapore, using local operator StarHub and M1, not China or Hong Kong operator. Similar situation as you? Can this be the reason we are getting same issue but other guys are not facing?
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] gadfly:
Thanks for writing. Nice to know I am not alone. In flashing hell at the moment. So frustrating. Also have a chinese ticwatch pro 4g *only available in china got it to work with google but it crashes. About to give it up with the yotaphone ..... unless you have another idea. I have a feeling there is no ROM for the 64gb yota3+....the taobao sellers are only selling the 128GB in international version.

Please write if you have any success. I am in germany but travel regularly to China.
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] simonkin:
Will retry and let you know if any progress, I believe this issue will resolve in case Yota 3+ continue on sale in other country, so we can have more ROM version to test.

My suggestion is: do not buy those made in China if you have other option, even they are cheaper and looks beautiful, because the people in firewall are live in totally different environment and ecosystem, you clearly know that ;)
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] gadfly:
Hello Simonkin, how did you flash BACK too the CN ROM? There was a link here in the thread for the original stock ROM but I could not Flash It... I think it was the latest OTA update and not the original stock ROM. Where did you get yours? Thanks.
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] simonkin:
Hi gadfly, I send you a private message in forum for that few days back, not sure if you received, please check.

Retry today flash to 3+ again with develop mode on, when a SIM card inserted, in setting -> system -> SIM status, the radio for voice and data are off. Still don't get clue, maybe there are mechanism in baseband of 3+ rom to power off the radio when it detect Yota3?

Next step I'll try to flash the 3+ rom with old bandband from Y3, then root and replace RIL(radio interface layer) file from Y3 too, let's see is it works....
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] gadfly:
Got your message. Thanks for the info. Was unable to sign into Baidu ... software still all over my PC but I could not sign up with a German telephone number....drat. Hope that you are more successful at getting a working baseband. So need a new working phone. Yotaphone was always so cool with the e-ink screen, especially with plane tickets that would display even if the battery was dead .....PRICELESS. Debating about getting an international Yota3+ my next Beijing visit. Let me know what you find out. Thanks for sharing your experience. Keeping my fingers crossed. Strange that no one else seems to have this problem.

The company behind the dual-screen YotaPhone is bankrupt

https://www.theverge.com/2019/4/19/18508418/yota-devices-bankrupt-yotaphone

What that means for all we, users of yota 3?

Very bad news! ?
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] Lukhach123:
hi guys, since i updated yota 3 to yota 3+, i don't see the multitasking button anymore (it appears before clicking Recent). How can I run multiple apps on the same screen?
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] simonkin:
Hi Gadfly, I resolved my sim card issue, it's a kind of corrupted baseband information, same as empty SIM / unknown base band issue happen on any android phone. Suspect something done on the phone before and someone fix it not in correct way and make it partially work, as it's a used phone I purchased from taobao. Here is the step what I have done, for your information.

Preparation:

* backup the phone partition modemst1, modemst2 and fsg, so you still have chance to restore in case my solution not work on your phone. better backup qcn file as well, using Qualcomm QPST -> software download -> backup.

Need to root the phone first

adb shell

su

dd if=/dev/block/bootdevice/by-name/fsg of=/sdcard/fsg.img

dd if=/dev/block/bootdevice/by-name/modemst1 of=/sdcard/modemst1.img

dd if=/dev/block/bootdevice/by-name/modemst2 of=/sdcard/modemst2.img

please change the right destination folder on your phone, remember copy the files to external sd card or on you PC

* write down the IMEI (sim1 & sim2), MEID, wlan MAC, for later write back.

Steps:

* enter fastboot mode, clear partition modemst1 and modemst2 using

fastboot erase modemst1

fastboot erase modemst2

I didn't clean fsg, this partition is supposed to keep the golden copy for baseband information

* reboot the phone, it will show no SIM number and empty baseband version.

* enable the diag port on phone:

adb shell

setprop sys.usb.config diag,adb

* restore the attached qcn using Qualcomm QPST -> software download -> restore. (I'm not sure is this step necessary but I did)

* open QualcommTool-eMMC tool, write back the IMEI, MEID and wlan MAC. Double check before you click write button, this tool seems can only write when the value is empty, you may need back to step 1 in case do wrongly.

the eMMC version I found is V3.2, it may show fail when write, but still success because when you read again the value show correctly.

* reboot the phone, if baseband version still empty, try flash the baseband file NON-HLOS.bin again.

My phone signal appears and radio is active now after all these things done, now the voice call and 4G works fine. For your reference, and good luck to you too :laugh:
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] gadfly:
WONDERFUL. Great work! If I can unbrick mine I will try.

Do you think the Samsung phones from China are easier or harder to get to international ROM? Thanks again!

---------- Post added at 08:15 AM ---------- Previous post was at 07:33 AM ----------

Question: Did you do these steps with the original stock ROM or after flashing the 3+?
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] simonkin:
I do it after flash to 3+, but need root for 3+ using Magisk, to enable diag mode for eMMC.

For Y3 CN stock version, that will be easy, just enable in menu of factory test mode by dial *#*#9738#*#*

Samsung phones will be easier, more resource and rom to choose, just don't buy those model made for China user only. Unlock the boot loader, then you can flash the baseband and rom you want.

hard bricked Yota3

Succesfully hard bricked my Yota3. While it was easy enough to open it up, 2 screws and snap connectors, no adhesive, disconnecting the battery, and try to short the jtag pins wont get me out of 900E and back into QDLoader 9008 mode. :confused: but c'est la vie.
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] Colognese:
A big THANK YOU to all contributors in this thread. I was a newbie when it came to android modding, but I learned enough about ADB, fastboot, EDL, bricking & unbricking... to finally upgrade my Yota 3 (128) to 3+.

Some tips I want to share:

- use the latest (original) ADB/fastboot package from google when on Windows 10. The "15 seconds installer ADB & fastboot 1.43" package is not enough!

- use QPST 2.7 build 474, not less

- there is a BIG difference between commands such as "fastboot flash boot rec.img" and "fastboot boot rec.img"! One can lead to soft bricking when using the wrong image

The Y3+ is now workking flawlessly, except the camera. Has Yota use a different camera on the physical 3+ so that the new firmware cannot use the camera of a stock Yota3? When using YotaCamera app, it just tells me that no connection to camera is possible. I even tried different camera apps, but to no avail.
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] cabvey:
On the standard (not flashed from Y3) Y3 + with the camera, the same story. This is, unfortunately, an error in the latest update. The camera is the same on both Y3 and Y3 +. No one yet knows what to do, as the developer is bankrupt, and no further technical support is expected.
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] Colognese:
Thanks. Yes, I was aware of the bankrupty. Anyway, the upgrade still make it much more usable...!
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] lokin:
is it the OTA service stopped due to bankrupty??
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] eReader Fan:
I was about to buy a yota 3+ when I devided to enter here to read some opinions, and now I know it is bankrupt.

If it was working ok it will be enough for mr, but the camera problem you all seem to mention, the impossibility of not seeing videos on landscape mode in EPD screen and also the situation where you dont see incoming calls on EPD screen completlly discorages me to buy it.

Is the ROM free to be modded for the programming magicians of this forum? Maybe this is the only thing it could make me buy the yota 3+
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] :
I think yes.
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] valeryhugo:
Hey Gadfly, sorry for your brick :(

but since you opened it already, would you mind recording a video of how to dissasemble your yotaphone ?

It could help the community understand better how it's build and how to repair (I'm thinking about the battery in particular)

I'll be willing to send you a tip if it can help.

Thanks!

Hey guys,

I had issues with my battery suddenly not lasting more then 6-7h and found out about the possiblity to upgrade to yota+ firmware.

So I upgraded my yota to yota+ 8.1 but I still have the battery issues.

According to CPU Spy my phone never goes into Deep Sleep (or just for a few seconds after booting), I have minial apps installed, and tried a wipe of the cache in recovery mode.

Also checked with wakelock and theres no apps really stopping the phone from going into deepsleep.

According to system battery info, first it showed bluetooth using up all battery (disabled that), then it was just the system.

I thought about swapping the battery, but the device not going into deep sleep doesnt sound like a battery issue to me.

Any help is appreciated!

Thanks
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] Spleeno:
yeah, the battery life on the yota 3 is a ****ing ****show compared to the yota 2. even with no running apps and in airplane mode (and with a pure white lockscreen on the epd) it can go from 100% to 50% in like 8 hours and as you've already mentioned: it's because it never goes into deep sleep. if you check with any wakelock app that can display kernel wakelocks (like wakelock detector) you can see that epd_pmic runs like 200 times per hour, even when the epd doesnt need to display anything (white lockscreen...)

my yota 2 lasted like a ****ing week with my usecase and the yota 3 can barely make it to 2 or 3 days, depending on how much gets lost doing nothing overnight...
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] Wrik:
Cheers for the reply.

The battery was lasting through a day for me which is all I need, but now it barely last 6h even when left untouched. Also the battery drains even when turned off. (not always)
[YotaPhone 3 ROMs, Kernels, Recoveries, & Other Dev] simonkin:
Hi Colognese,

The Y3+ OTA is not avalaible, but the upgrade files are still there on Amazon cloud server, here is the link of upgrade file list in xml:

http://s3.ap-northeast-2.amazonaws.com/ydfiles

In xml you can found the zip or tar file named from Y3-50 to Y3-54, what I know is the Y3 to Y3+ rom pack is based on version 52, so only 53 and 54 will helpfully on phone upgrade. To download these 2 files, you need to append the file name after above URL, ie.

http://s3.ap-northeast-2.amazonaws.com/ydfiles/ota_update-Y3-54.zip

Y3-53 is a very small fix package, only recovery.img is valuable, but don't know why the recovery screen became a falling down robert after frash, so no use also. The Y3-54 upgrade a 1.3G big package, with full image of boot, system and vendor, which contain the latest official upgrade. But unfortunately, there is no place in Yota3+ updater to choose local download file, also installation fail using recovery, so the only way is to manually extract the image and flash, step as below:

1. unzip file ota_update-Y3-54.zip, there is boot.img, which can directly flash via fastboot. Also there are compressed system and vendor partition,

system.new.dat.br

system.patch.dat

system.transfer.list

vendor.new.dat.br

vendor.patch.dat

vendor.transfer.list​

2. unpack the file, you will need Brotli to convert .br file to .dat, then using sdat2img to conver .new.dat and transfer.list to .img file.

3. inally you will have system.img and vendor.img file you can flash via fastboot or flash via 9008 by replace same file in pacakge.

you can try by yourself, or download the file what I done at https://www.mediafire.com/folder/ii6qj1svoclv0/ , good luck :)

Hi YotaPhone comunity.

For sure some of you remember the beautifull tower clock cover of yotaphone2.

I loved that, but I dont know a way to do an adaptation for put it in some way on the back of Yota3+ (as live wallpaper of epd lockscreen or as widget on the panels or I don't know).

Please I know all of you are so good on this or you know where to look for answers.

Thank you all!

Hi!

I had the same problem too.

I uncheked all the background check (developer option - > backgroung chek) and now the battery long last for all day, it stops to drain during screen off (i also replaced nackgroumd clock widget with android widget and not using anymore weather widget). Also, I unchecked almost all google accounts sincronisations and activity controls (like location history etc.).

Some time I restart the phone if it seems to drain battery faster than normal, but not sure it is really necessary.

It is just a workaround, but I didn't feel any malus in using the phone.

Which version of android will flashed on this update? Can I use it in Indian networks

I have plan to buy yota 3 and flash yota 3+ firmware into it. I am living in India I have not verified either yota 3 or yota 3+ will support Indian LTE network. There is a significant price difference between yota 3 and 3+ in aliexpress. As per my understanding the only difference between yota 3 and 3+ is the firmware. I hope this rom is the latest one too. Please clear my concerns. :)
