Hi everyone,
I hope my question is posted in the right forum...
I have Samsung Galaxy S4 i9515 LTE and I have installed that firmware update to Android 5 - sammobile.com/firmwares/database/GT-I9515/ , but now it turned out that the update is appropriate for that model, but without LTE support... so my phone now connect with 3G only, no LTE connection support is there.
I know it was my mistake. Now I'd like to go back to Android 4.4.2, but I heard some time that reversing Android versions can damage the device. How to do that properly?
Thank you for any help!
Please post the following information:
1. Model Number
2. Android Version, found by going to Settings > More > About device.
3. Firmware Version (AP, CP, CSC), found by dialing *#1234# in the dialer or by installing Phone Info from the Play Store and running it.
4. Service Provider
5. Country
6. Is the phone rooted? (Yes/No)
7. Is a custom ROM installed? (Yes/No, and the name of the ROM)
Eh, actually in the evening LTE started to be there.... . Sorry guys, I was sure it was by the software that LTE is not working. Maybe it was some network operator problems.
Only difference I see now in Android 5 is that I have "LTE" sign instead of '4G" like it was in Android 4.4.2.
Sorry for confusing post .
Glad to see you got things resolved.

Hey man,
I did not find the android version 5 lollipop from the link you provided (sammobile.com/firmwares/database/GT-I9515).
There is only 4.4.2 for alll countries. Is ur rom a custom rom?
Tnks, sorry bad english.
You didn't look hard enough. It's there on the page. Just NOT at the top, like you would expect.

Hello
I ordered a Yotaphone 2 YD201 from china not long ago, and after recieving it I decided to check the phone's details to make sure I'd received the right version.
Unfortunately, I had received a YD206, which won't work well with 4G networks in the UK.
I contacted the seller, and he assured me that the phone I have received is in fact a YD201, stating the following:
"a few yotaphone YD201 was reflashed to YD206 before sending , pls check the phone after delivery . If your phone is YD206 system , don't worry ,it just softwareproblem , the hardware is original YD201 , we can give you reflash rom and tutorial to reflash it back to original YD201 . It will be YD201 system and work with B3/B7/B20 4G net"
My question is; is there a way I can find whether the phone was originally a YD201, or if the version I have been sent is actually just a YD206?
Attached are some screenshots containing my device's info.
Any help would be much appreciated
Thank you

Imei = 356... -> yd201
imei = 359... -> yd206
The difference between 206 and 201 are the radio bands supported.
To flash radio only:
fastboot flash modem radio\NON-HLOS.bin
fastboot flash sbl1 radio\sbl1.mbn
fastboot flash rpm radio\rpm.mbn
fastboot flash tz radio\tz.mbn
The chinese model is compatible with 1800Mhz LTE band, that is used in some contries in Europe also,
On the phone dialer if you insert *#06# it will show the phone IMEI.
The I.M.E.I. stands for International Mobile Equipment Identity and is specific for each country,
IMEI numbers starting with 359 will be Chinese YD206, if this is your case, then you must flash the Chinese Radio even if you use other location ROM, the correct installed radio will give you better battery life and network speed.
Keep in mind that the Information on Android -> About the phone -> Model: YD201 or YD206 is not accurate because it gets its information from the ROM and not from the hardware.
Thanks for the help

Hi. I'm sitting with the same dilemma... I received the same explanation from Geeks Planet Store, word for word.
I do not even understand why they would even consider re-fashing something with a higher value (YD201) with the software that would make it look like something of lower value (YD206).
Anyway in your screenshot it says Baseband version ..._CN1_M05. Does this mean it uses the CN radio firmware?
I also downloaded their suggested firmware from the link they sent. In that there are no files under the radio folder. Does that mean the radio firmware is supposed to stay unchanged in this case? If so and if baseband _CN1_ means it is currently running CN radio firmware, does this mean the hardware is really YD206?
One more question: how reliable is the imei number check?
To me the best approach seems to be the suggestion by cvzalez to really test the radio with different firmware and see what works.

I'm confused too as to why they would re-flash a YD201 to a YD206. It doesn't make any sense.
According to this guide, the 'S01_003_3034_CN1_M05' baseband that we have is the one used by YD201s that's supposed to work with all available frequency bands. The reason for the radio folder being empty is so that flashing the phone leaves this baseband as it is.
As for the imei number, after a bit of research I've found that changing this number is relatively easy (even without root), so it's possible that Geeks Planet have just changed the imei number to make our phones seem like YD201s. However, it wouldn't make sense for them to do this and to not also flash the firmware to YD201 as well.
Have you tried flashing the phone to the YD201 using the instructions they've given you? I'm wondering whether or not to try this myself.

I have not received the phone yet. Even though I ordered it a very long time ago, it was only sent after the Chinese new year holiday.
I am seriously considering not accepting the delivery...

I might be wrong or blind, but when I look it says: "YD206 users have to change their modem components to CN version, in order to have all the available bands working. The modem version is written in "About Phone", under "baseband version". You must have the S01_003_3034_CN1_M05 version. "

I've asked the supplier if they can give me any assurance that they would help me out should I follow their flashing instructions and the phone be damaged as a result.
If they can give me this assurance, then I'll give it a go and give you the results.
Reading the comments on the youtube video Geeks Planet have sent me, it seems like this problem isn't exclusive to just Geeks Planet and is rather an issue with the main supplier of these YD201s. The comments state that both coolicool and e-fox have sold people phones with the same issue and have been linked to this same video.

The wording of this section is a little difficult to interpret. It's not really clear if baseband 'S01_003_3034_CN1_M05' is the original baseband or the international baseband.

It really looks like _RU1_ is for RU, APC, HK, EU, ME
and
_CN1_ is only for CN
(So YD206 needs _CN1_ ?)
Guys, you're lucky! You've a YD201, it doesn't matter if the firmware inside is from YD206, it can be easily changed looking at the guide you already linked.
The fact that they flashed a firmware for 206 to a 201 is because their phones are suited for Chinese market.
All you have to do is to flash the RU version (including its radio folder) and see that all LTE bands will be working as expected on a YD201!
Changing IMEI is possible, but not simple. And if your IMEI in "About phone" is the same on that written on the package of YotaPhone, you're good to go.
IMEI checking is the most reliable way to understand if it's a YD201 or YD206.

The one on Yota ftp site are official. I don't know if the firmware the seller sent to you is modified or they just downloaded it via ftp, repacked and sent to you. The firmware version is invisible looking at the files, first you have to flash it and them you will see which version it is.
Personally I would flash only official firmwares.

At least the baseband changed... which I guess is a good sign. For me now the big question is: Does LTE B20 work? (That is what I need where I live.)
Hi!
I just got SM-G9500 (bought in Taiwan), and internet is not working, I believe have tried everything in the settings. Phone unlocked, LTE sign next to carrier on top is there, everything else is ok, except data network. SIM on other phone (S7) works fine. Yep, me located in Europe (Vodafone HU).
Is it possible to get 3G/4G with this phone with my operator? If yes, can one point me to the direction how to achieve this?
Baseband G9500SQU1AQC9, Kernel 3.18.30-10318693, Build version SEPF_SM_G9500_5.0.2_0008
Please help!

Well, I just posted a link where you can see that there are only two countries listed ... or differences in S8 models (and processor) does not matter, so I can take any S8 file? ... I am aware of this principle, but dont see anybody did it in similar case as mine (or with G9500).
Still waiting for opinion/ideas...

Yeah it will make a difference, that phone is only for far-east markets, hence the firmware, you can try the Hong Kong version, but I wouldn't hold my breath. Far east models run very different frequencies on their modem I believe, could be wrong though
you don't need to flash anything.
you have a Galaxy S8 (SM-G9500)
your phone "speaks" all known wireless frequencies (from the factory) & it can be used anywhere in the world.
The LTE icon just means your phone is registered on the LTE network.
It doesn't (yet) mean you have internet access.
you're 1/2 way there.
at least your LTE works.
You need to contact Vodafone HU helpdesk & ask them to give you the "Access Point" details for their network.
** Normally network providers send you these details in a text message - the first time the phone connects to their network - but maybe you didn't accept the settings / deleted the text message?
Once you have the settings:
Go to: Settings / Connections / Mobile Networks / Access Point Names <--- select "ADD" & then enter the details provided by Vodafone HU & save the access point details.
Your internet access will work after a couple of seconds.

Hy, I'm hungarian too,and i'm just writing in english because of forum. I bought also an SM-G9500,and i still didn't get Oreo. Or any softwer updates since january. If you want, search me on facebook, Gyarmati János István.

A co-worker of mine just had their office moved and no longer gets cell phone reception in their new office. I tried to help them enable calling/sms over wifi but it looks like they have the samsung firmware on their phone and are on verizons network, and she'll need the verizon firmware installed to enable calling and sms over wifi. I tried to flash the verizon firmware to her phone with Odin but the flash failed. The firmware currently on her phone is G950u1UEU5CRH3, which leads me to believe that she currently has a version 5 bootloader installed, and the VZW firmware I tried to use was for bootloader V2. Is there a stock verizon firmware I can download that will work with the bootloader version she currently has?

yes, but that's the fact, on the pcb it says g950u, and the chipset is detected on PC qualcom, but the cellphone information says g950f and when dial * # 1234 # shows the results like this
but if I use the dial code * # 12580 * 369 # it will address the results like this
then when I use the 'phone info' application the results are like this
So its a950 u. With 950f stuff on it. Probably unlocked and setup to run on a international carrier. The bootloader version of the important one. And what i would go off of
and this test results from 'miracle thunder' addressed the results as shown below
like this
I blinked using the G950u and G950u1 all failed, luckily my cellphone didn't bootloop,
