Yotaphone 2 Frequency and Radio Firmware - AT&T - YotaPhone

Hey guys -
So like many of you, I reflashed my two Yotas to the latest RU Lollipop and was wondering if there was another radio firmware file that might wake up the AT&T US LTE bands. Any thoughts? Has anyone tried flashing the different radios to see if you can get a 4G LTE signal stateside?
Thanks,
Rootdude

what upload/download speed do you have now?

I have HSPA+ on AT&T . Can you help us with US modem firmware for LTE?

HSPA+ can be sometimes very good - 3-15Mb/s - what is your speed at the moment? can you check through speedtest.net ?

At&t firmware
I have around 3.5 mbs to download and 0.6 uploaf. Too small comparing local 4G. So, can you help us?

I do not think you can change that easily, there's a thread talking about changing Radio Bands but the conclusion I got from the reading is that it does not work, at least with current "user" knowledge, YD206 is from China or HongKong, and some of those LTE Bands can work in Europe, not so much on the USA, the bands that USA telephone companies are very different than Europe or Asia, and as such YD206 IS NOT compatible with USA LTE bands. UMTS can have much higher upload speed than the ones you posted, so it might be your network problem, don't know if they are any better in LTE over your region.

Should be possible
Qualcomm 8974 supports all LTE bands. We just need proper modem firmware for US bands. Method in those threads definitely doesn't work since Qualcomm introduced some hidden filters inside firmware

BTW, there is lte_prefferedband file in the modem folder of Yota EFS. Does anyone know how to edit it?
That might be a anti-tampered code against our NV changes

Ok, I found out. For AT&T we need qcn file from Yotaphone 2, model 205. I don't know it such thing exist on the market but this reference says that it might be compatible with At&T.

interesting thing is that YD205 model was never launched, so it doesn't exist at all, unfortunately. The inquiries about future developments of this model were negative...

I can't find Canada Bell S8500M firmware anywhere! Need help ASAP!

Okay here is my situation. I have a Bell Canda S8500M phone that I flashed with S8500XXKF2_Full_SHP_sYCO firmware but now lost my UMTS 850/1900 bands so no more 3g signal =( I only get edge. I looked all over the web and can not find the S8500M bell canada firmware anywhere!! I found the Latin America firmware S8500L S8500LUHJL1 that i flashed and got my 3G back but Kies wont let me log on to Canada Samsung appstore anymore.
1)Is there a way to flash my phone with a European firmware while maintaining my UMTS 850/1900 bands from my now S8500L?
2) Does anyone have the original Canada s8500M firmwares??
3) Can I flash part of another Euro S8500XX firmware but keep my 3G bands?
4) devs can you implement a North South America 3G friendly hybrid firmware?
Any help or suggestions will be highly appreciated.
1)you can use the European firmware and get 3G signal too by flashing the whole European firmware except amss.bin (contains modem config) use the one from S8500LUHJL1
2) Don't know where to find those
3) if you mean by the bands 3G then it is same question as 1 with same answer
4) i am not a developer so i don't know if they can
Best Regards
Thanks for your response I will give it a shot and see if it works to flash the Euro firmware without the amss.bin.

I flashed the modified S8500DDJI2 on my phone without the amss.bin file and it worked! I still have my 3G connection and hacked firmware!! =) thanks a million!
Has anyone had success doing the above (keeping the amss.bin file to retain phone's frequency band) while flashing with a Bada 1.2 firmware?
I too want to keep my phone (8500T) 850/900/1900/2100 compatibility.
I have tried flashing S8500XXJID (Euro 1.2) while maintaining my S8500L amss.bin on my Canada Bell S8500M and no luck. No go on the 3G on 1.2 BADA for 8500mhz/1900mhz devices. Maybe a DEV can help implement this in a Hybrid 1.2 firmware with those bands supported.

I9505 on T-Mobile USA

Hello
I'm thinking of buying the international Galaxy S4 i9505 and use it on T-Mobile here in the USA (rather than the T-Mobile m919 variant) ...I am aware that i9505 doesn't have HSPA on AWS band and that's fine because most of my area has T-Mobile LTE which works on the 1700/2100 MHz band (band 4)...
Does anyone from the USA use i9505 on T-Mobile and get LTE ?
Another thing, is it possible to flash m919 radio on the international i9505 to have the lacking LTE bands if any ?
A note : according to gsm arena,i9505 has APQ8064T but couldn't find what chipset the T-Mobile m919 has...If they use the same chipset it would be likely possible to interchange radios between the 2 I suppose...
Any ideas are welcomed..
Thanks
I am in same situation.
We need answer about this From the user or developer who has Experience with this case.
Best Regard to all
any help???
I9500 is the international version, i9505 is the US version

Recovery, go get the modem you want from tmo forum. and flash it, I do not think it is a good idea, but if you feel it is needed. So be it.
Thanks for the Thanks.
DO NOT flash modems. Flashing modems to enable frequencies has NOT worked on S3, Note2, S4 i337. Don't do it.
"You don't think" doesn't mean "it's not possible" or "a disaster will happen"
I used my skyrocket on T-Mobile after flashing a T-Mobile radio from Hercules (very closely related device to skyrocket... both are s2 variants)....
So please stop the useless advice of not recommended, or not advisor or such... It's xda not Facebook..
If 2 devices has the same chipset and/or the same hardware platform it could be very likely that the only difference between then is the radio software and the commercial name,. Unfortunately I couldn't find enough detailed (deep hardware details) info on the T-Mobile S4...
The main purpose here from this thread is that did anybody here try it and connected to T-Mobile LTE in USA successfully ?
Any update??
Sent from my Nexus 4 using Tapatalk 4 Beta
I would also like to know if the i9505 can connect to T-Mobile's LTE in refarmed areas. I'm holding out on the purchase right now but if it does work then I'll go ahead and buy 1.
As I understand it, I don't believe that the I9505 can connect to Tmo's LTE frequencies but it should probably get unto the refarmed (1900 mhz) 3g areas if you're in one of the big cities (ie; NYC, LA).
It looks from the specification that out of the box it will not work..It doesn't have the 1700mhz LTE band(which T-Mobile USA uses for the LTE uplink)..
For sure it'll need some"modding" or radio flash to work...
We need a guinea pig big-time here lol..Probably somebody buys it, flash the S4 M919 radio on it and report back...If it doesn't, ship it back to seller for a refund...
PS: it is useless if it won't connect to T-Mobile LTE(i.e. just 3G)..Pretty much everywhere will get LTE eventually...
We are still waiting for real Solution.............
so is it mainly coming down to the radio thats built into the chipset and not the software side of things, I wanted to flash the modem but I dont know if it will brick, blow up, or turn into optimus prime.... any ideas lads,
cheers

You have I9505 ? Are you on t mobile ? Do you have a good return policy for the device ? And in the return period ?
If so and you're brave enough, look for a flashable m919(T-Mobile S4) radio zip and flash it using any custom recovery ...Beware that this action might corrupt its imei or might cause a big problem that can't be corrected easily... So you're responsible for that ... But if successful you'll be able to use T-Mobile LTE and do the community a great service...,
Please let us know if you have any updates.

4G on D802 HKG version

I have a D802 Hong Kong version. In the secret menu (3845#*802#) i have found this: LGD802AT-00-V10C-HKG-XX-NOV-30-2013
Now, I would like to use the 4g connection in my country (Italy, carrier TIM) but the 4g option is not avaible in "network mode". After a test with another G2 (italian version and same carrier), I can say that the connection don't switch automatically on 4g but keeps the H+ one. So i think is necessary a modification.
Solutions?
Is it necessary to flash an europe radio? or something else? I'd like to keep the stock rom Lg but is not a fundamental.
Baseband: M8974A - AAAANAZM - 1.0.190036
Kernel: 3.4.0
Build: JDQ39B
I have the g2 for two days. I know it very little. I do not have much knowledge about it. Some good soul can explain to me how to do?
I need your help!
Did you verify that the device has the correct radio bands for the lte on that carrier?

I don't know how to check! On the box of g2: gsm 850/900/1800/1900; wcdma 850/900/1900/2100; LTE 2100(B1)/1800(B3)/2600(B7)/900(B8)/800(B20).
My carrier is Tim but i don't kwow which band uses.
In secret menu/LTE Band section: avaible band 1,2,3,4,5,7,8,17,20,40. No one is selected.
Can i flash V10E firmware for Italy on V10C firmware for honk kong (actually on my device)?
Flashing different firmware wont help. Its either your apn is wrong or you didnt enable lte correctly. I checked and TIM uses 1800 (band 3) lte which your phone should work with.

Hi,
I've a similar question and I hope someone could help me: I've a G2 phone using the D80210e-ESA-XX firmware.
In the product specifications, supported LTE frequency bands are 900/1800/2100/2600/850. I know that in Italy working frequency bands are 800/1800/2600. Now, my phone does not support 800 MHz: do you think is possible to upload a different firmware (IT or EUR ones) on my phone? With one of these firmware, does the device will work at 800 MHz?
Thank you so much.
I also had the D802 with Korean firmware!
Even though the phone itself supports LTE the Korean firmware doesn't!
I flashed the EU version and everything worked fine afterwards!!!

@popsi, @zacharias99 did you follow a specific procedure to upload the european firmware. I'm not so sure to perform it cause some month ago I've bricked an old Motorola (I don't remember the exact model) using simply a firmware of a different country. The result was a brick cause two firmware did not use the same way to allocate the memory...

My friend i don't really know where in this forum the instructions for flashing a new stock firmware are... (I am also new in this community)
And i flashed it with Greek instructions so my link won't help you and i don't want to post some link i haven't tested by myself...
Sorry i hope you can understand!
At moment i have no time, but if I would be you I would search in the G2 Section for instructions!
They must definitely be somewhere!

@zacharias99, I've checked that 4G can be enabled using the secret menu
1. Go to LTE-Only
2. Modem Settings
3. RAT Selection
4. Select GSM / WCDMA / LTE auto
as in the post http://forum.xda-developers.com/showthread.php?t=2494751
At the moment it doesn't seem to work for me, probably because my sim still has not been enabled for 4g.
Have you ever enabled this option (with the previous korean firmware, I mean)?
@zacharias99, @popsi: the new european firmware allows to navigate over the 800MHz frequency band for you?

EXPERIMENT: Flashing the WW LTE firmware onto the US LTE variant

Recently with the delay on 5.0 for the US LTE variant, because of AT&T, I have lost my patience with them. I am looking for a way to rid myself of this BS while maintaining full stock software. I have heard that the variants of the tablet are actually not different, and the firmwares may work on either model. Has anyone tried this? I'm well aware the cell bands supported may change (but my carrier only requires one band, and the WW variant supports one of my carrier's bands). I would love to know if it works, and if I can dirty flash the package to keep my data, since the rom is basically identical.
I flashed OTA posted in general forum for LTE and using it in ATT. Unlocked bootloader, CWM, and root afterwards. I'm not quite sure what you're looking for?

Bricks.
No what i'm asking is if i could convert my device to the WW variant with a firmware flash, and thus avoid needing to manually flash OTA files becauze of delays. I know this isn't going to be the last update delayed on the US variant so i'm wondering if i can just switch the installed software from the US LTE version to the WW LTE version, without bricking.
Yeah.. I am thinking the same thing as well.
If it was possible without bricking the device, I would love to flash the "Rest of the World" firmware on the AT&T set too.

You're welcome to try it with the factory images. If it does brick, you can always restore through the same process. I plan on attempting it soon, but i am waiting on a microsd card.

Theoretically, the only thing that would be changed between builds is the GSM stack. However the OTA between the WW and the US version would not work by default. You'd need to go into the OTA zip and mess around with some of the build.prop info. Which then may cause MD5 mismatches when it is parsed, and would definitely affect subsequent OTA updates because of MD5 mismatches.
If there are Android 5.0 factory images available for the WW ROM you feel would be suitable for your geography, then this would be the safer way to proceed.
I remember when I owned a Samsung Galaxy S2, there was an XDA thread with flashable modems you could push to your device to get better reception in your area. Essentially the differences between the WW and US/CAN versions should only be the GSM stack, and perhaps some carrier-specific bundled app (like the AT&T app for example).
Just a quick update for those who are interested:
Well ... I just did it. Successfully flashed the RoW recovery image on the Shield Tablet LTE set which I purchased from US via Ebay. I'm still in the process of restoring but so far everything seems to be working fine.
Confirmed 2 things during the flashing of recovery image,
Quote:
1) Issues of Cellular/Sim Card on the US LTE set is almost certainly Lollipop firmware related. No problems on FW 4.4.2
2) Problem of Wi-Fi authentication error after sharing files via Super Beam ( Wi-Fi direct ) is also resolved after revert to 4.4.2
I think I will be sticking with 4.4.2 for now with the added bonus of file managers working on Kit Kat.

Thanks for the update. I am interested in this also.
So i'm assuming from your post you got LTE working? Which country are you in? Where do you get the factory images from?
I live in Australia and have the US LTE version. HSPA+ is good but it would be nice to have LTE working on my network (Telstra).

Actually, I don't have a 4G LTE micro sim card with me so I can't verify that at the moment. I am trying to test it out using my friend's sim card and will report back with the results. In my opinion, it's not a good idea to be trying my nano sim on this.
I'm from Singapore and the network I'm on supports LTE Band 3 & 7 and my AT&T Moto X which supports Band 7 works out of the box.
Got them from Nvidia developers website but you have to register for a free account first.

Yep I need LTE band 3 for my network which is not supported out of the box by my US LTE shield. If your network supports LTE Band 7 then your shield should also be able to access your LTE network as BOTH the US and RoW LTE shields support LTE Band 7.
So I don't think your experiment will help me. Is there any way finding out which LTE Bands your shield supports now that you have flashed the RoW recovery image?

I am not really an expert on such matters but let me try and if it's possible to find out the information you are looking for.
Why not try flashing it and give it a go ? There's the bonus perk of removing the AT&T app from the device.

Hi, I am currently using US LTE NVIDIA Shield Tablet in Singapore as well. I have successfully flashed the RoW recovery image to my tablet (since I'm downgrading from Lollipop as well, so I thought I might as well try), but I noticed that there is no baseband file in the recovery image package. I proceeded to flash anyway.
One thing I noticed after flashing is that I still am not getting LTE (half of Singapore is band 3, and my home is under its coverage). So, it's pretty safe to say that the baseband is not affected by the factory image.
However, it might also be that the latest recovery image doesn't cover the baseband, and it might be included in the previous updates. So, I'm trying to download the previous recovery images and see whether there are baseband images are there.
EDIT: baseband image is not in there. The baseband version is definitely still for North America (e1729-nala.4.05_0.6.3 @786934, notice the 'na' part?).

Sorry I don't really understand ... the RoW software cover for both Band 3 and 7 since the UK edition supports these LTE bands as specified in Nvidia FAQ.
You should still be able to get Band 7 coverage which the NA edition supports as well, right ?
Am I missing something ?

Thank you. That is exactly the information I was looking for. Unfortunately there is no point flashing the RoW recovery image if you wish to change your baseband (and then use different LTE bands like I want to).
Is there anywhere I can download the RoW baseband images? I remember they were readily available for my nexus 4.

Sorry I don't really understand ... the RoW software cover for both Band 3 and 7 since the UK edition supports these LTE bands as specified in Nvidia FAQ.
You should still be able to get Band 7 coverage which the NA edition supports as well, right ?
Am I missing something ?

As I said, the image doesn't include the baseband image. So, no matter what you flash on the rom side, it won't matter.
Also, about band coverage in Singapore, it's not a full overlap. Some areas are band 3 (south and west), while some band 7 (North and East). I know this from an M1 engineer friend. So, yeah, no LTE band 3 in this factory image here.
But not all hope is lost. If one day Nvidia decides to update baseband, it will then definitely include the baseband in the OTA or factory image. So, possibility of switching is still there.
Was there a baseband update with the latest software update (2.0)?
The factory images for 2.0 have still not been released.
In another strange twist when i turned on my tablet this morning I was surprised to see my US shield had LTE here in Australia. Which means only one thing - Telstra are expanding their LTE spectrum in my area!

I downloaded the OTA manually and checked the content. It doesn't have any baseband update. Also, just to confirm again, I actually re-installed Lollipop. The baseband is still unchanged (only the suffix @ part changed, but I think it's just some marker).
I checked wikipedia, and it seems that Telstra has band 3 and 28. There's a good chance that they switched your area's band to 3, or they simply add band 7 (the latter is, of course, ideal).
I read that Nvidia is preparing an update to the existing Lollipop system. Hopefully they will include a baseband update, then we can probably make the jump to the RoW ROM. For now, I'm sticking with the US ROM first.

Okay ... I see that you are not able to get Band 3 coverage. But just to confirm, you are still able to get band 7 4G LTE coverage on the ROW Rom right ?
My phone 4G LTE is on Singtel, getting pretty good coverage island wide on Band 7. Unfortunately, it's a nano sim and I'm hesitant to test it on the tablet in case in gets jammed inside the slot.
So long everything works fine, I'm sticking with ROW Rom as it will probably not have none of the nonsense whereby it require AT&T approval before release.
Sorry to trouble you on another matter, I have reported this 2 issues to Nvidia customer support but just want to check if it's just my set or an common problem.
1) Cellular data connectivity will not return after enable aeroplane mode. SIM card is subsequently not detected.
2) After sharing files using Wi-Fi direct ( SuperBeam app ), Wi-Fi connection doesn't auto reconnect due to failed authentication. Require manual intervention.
What I can say is this 2 issues no longer occur once I downgraded the software from Android 5.0 back to Kit Kat 4.4.2

According to Nvidia faq, the North American version that works on AT&T, T-Mobile and Rogers on LTE bands 2, 4, 5, 7, and 17 and HSPA bands 1, 2, 4, 5.
I see that this article ( http://www.cnet.com/au/news/telstra-expands-its-4g-services-including-the-700mhz-band-trials/ ) states that Telstra is conducting trials for 700mhz (Band 17) in your area. Maybe this is why you have begun receiving 4G LTE reception in your area ?

I initially thought it may have been the planned 700mHz expansion by Telstra in my area HOWEVER Telstra's 700mHz expansion is actually Band 28 (not Band 17) and my US shield does not work on Band 28 out of the box. Although LTE Band 17 and 28 both use the 700mHz spectrum they both use different parts of that spectrum so are not compatible.
What I think has happened is there is some LTE Band 7 coverage in the middle of town here which is where I was when I got LTE coverage today. As I understand it Telstra has some limited LTE Band 7 coverage with most of the LTE network being Band 3........ so I'll still have to wait until I can flash a RoW baseband which will hopefully give me Band 3.....

Cross Flash From VS995/Verizon Unlocked to US996/US Unlocked?

I've been looking for a good, inexpensive phone my partner can use on AT&T, T-Mobile and Verizon and I was able to snatch an unlocked VS995 in excellent condition for $70--it just needs the battery replaced soon which I also ordered. The main downside to this model if you're using it on AT&T and T-Mobile is that it doesn't support Band 12 and 17, but I know the US Unlocked variant does. I just received the phone today. I've been searching on the forum for an answer into if this is possible with the VS995 variant and I've seen people say it is using an LG V20 version of LGUP, but haven't found anyone that's confirmed they've been able to do it on the Verizon and not the AT&T variant and the steps they took to do so.
I want to stay on the stock ROM so I'm not looking to root and install a custom one. Is it possible to convert from the VS995 firmware to US996 so I can gain band 12 and 17 while removing the Verizon bloatware and staying on the stock ROM/OS? If so, would anyone one of y'all be kind enough to post the link to a guide or article that details how to do so? I reset the phone to factory settings so thankfully don't have to do a backup. After doing this, is it still possible to receive OTA updates and, if so, are they gonna mess anything up like reverting the phone to stock firmware or the phone's unlocked status?
Thank y'all so much in advance.
I have a vs995 and I flashed it with US996_usa and working great. You need to download the us996 usa version (2.3GB KDZ) at lg-firmwares dot com and flash it with LGUP PATCHED. There is video on Youtube giving detailed instructions. You will be able to find all these easily via google. I don't know how any of this works with the various US carriers or bands as I'm in europe.

As far as I'm aware, cross-flashing firmware on the V20 won't give you any additional frequency bands unlike some other phones, so you're still limited to what the VS995 has from the beginning. From what I've read, US996 firmware works fine on Verizon except for a few features such as WiFi calling and video calling.
As for AT&T and T-Mobile, you won't get VoLTE or WiFi calling along with the missing LTE bands, so, depending on where you live, overall coverage could be significantly worse than having the H910 (AT&T) and H918 (T-Mobile) models, respectively. Not having VoLTE would be a problem if you were in an LTE-only area without roaming because then you'd have no way to make or receive phone calls.

Thank you for the info. Are you referring to this video? I'd watched it before but it's for flashing the stock ROM on a US996 variant and the links in the description don't work.

Hmm, where did you read that? From what I've read the hardware/modem in the VS995 and US996 version is the same and therefore the difference only comes down to the carrier firmware artificially disabling bands the device supports just like it is on many other smartphones. I could be wrong, but one way to find out would be to do it myself and then try to connect to a Band 12 or 17 tower.
WiFi calling and video calling I'm totally fine with not having. Never used or needed them. With AT&T and Cricket I've never not had service and with Metro the couple times I haven't had T-Mobile service roaming has kicked in and saved the day. Thank you for the info.

Here's some frequency band info for both the VS995 and US996:
VS995
US996
I'm pretty sure this is a hardware difference, and no firmware change will be able to add more band support unlike some other phones you may have heard about (such as recent U.S. models of Samsung phones). Otherwise, there would have been plenty of discussions and guides around here regarding this (and FWIW, I happen to own a US996, LS997, and H918).
As for LTE Band 12 on the T-Mobile network, only phones that are certified by T-Mobile will be able to access it (more info on compatible phones here). So even though a US996 has the hardware for connecting to Band 12, you wouldn't be able to use it since T-Mobile has blocked access to it and only allows it for the H918 model.
Based on all this, I would expect a VS995 to get LTE Bands 2, 4, and 5 on AT&T and T-Mobile. Of course, since you already have the phone, there's only one way to find out. Just make sure you carefully read the guides/procedures about using LGUP for cross-flashing, and absolutely stay away from any H918 firmware (it will instantly kill any V20 that is not an actual H918). Not sure if there even is a separate guide around here as it is usually mentioned in the initial steps of different rooting guides for each V20 model, but you can find the patched LGUP that ezzony mentioned in this thread (you may have to move the DLL file to a specific folder location for it to work properly).

Yes, but the Frequency Check website only looks at firmware differences, not the internal hardware. I decided to do some further digging and went to the source that tests these (the FCC) and found that the VS995 and US996 have the same ZNFVS995 FCC ID meaning they share the same internal hardware. Verizon just decided they wanted to be arseholes and cripple the phone's band support in their firmware so it wouldn't work to the best of its abilities on T-Mobile's and AT&T's network. Similarly, T-Mobile decided to also be arseholes by artificially limiting Band 12/VoLTE support to their own H918 model only. I hate that carriers are able to get away with this BS. It is incredibly anti-consumer and infuriating. If the hardware supports XYZ then it should be enabled and capable of taking advantage of it. The FCC tested Band 12/17 to work properly on these and says regarding the device's capabilities:
This device contains the following capabilities: 850/1900 CDMA (BC0, BC1), 850/1900 GSM/GPRS/EDGE, 850/1700/1900 WCDMA/HSPA, Multi-band LTE, 802.11b/g/n/ac WLAN, 802.11a/n/ac UNII, Bluetooth (1x, EDR, LE), NFC LTE Band 12 (698 - 716 MHz) overlaps the entire frequency range of LTE Band 17 (704 - 716 MHz). Therefore, test data provided in this report covers Band 17 as well as Band 12. LTE Band 25 (1850 - 1915 MHz) overlaps the entire frequency range of LTE Band 2 (1850 - 1910 MHz). Therefore, test data provided in this report covers Band 2 as well as Band 25. LTE Band 66 (1710 - 1780 MHz) overlaps the entire frequency range of LTE Band 4 (1710 - 1755 MHz). Therefore, test data provided in this report covers Band 4 as well as Band 66.

Seriously, f*ck both Verizon and T-Mobile. Thankfully I'm starting my Cricket/AT&T service in a week so I'll be able to test if it can pick up and use Band 12/17. You happen to know of any app or way to force/limit the device to only using one specific LTE band? Thank you so much for linking to that thread for flashing these using LGUP. I'll make sure to follow it and to download the US996 (US Unlocked, not US Cellular) firmware and post a small update on my findings. Thank you so much for all the info. Really appreciate it.

While I've never tried this, have a look at this old thread on LTE band selection from a hidden menu. The dialer code differs by model, so for a VS995 it would be *#546368#*995# and for a US996 *#546368#*996#. The code works for my US996 and H918 on Oreo but not for my LS997 on Nougat (for which there is a separate APK file to access the hidden menu). There are lots of submenus and items in there, so be sure not to accidentally change settings that you're not supposed to.

Hello
You crossflash with which android version 9 or 8
If android 9 whats the battery backup (good/bad)
Does the android 9 has a darkmode
Does it brings back or activate the FM radio ?
Thanks

Android 8.
I know Android 9 does not have FM radio because Android 9 is only available for the Korean variant (F800) and it never had FM in the first place.
