Figures, yup it's OF1. Great... Lol, guess I'll be happy with the great deal on phone service, and suffer without root a while.. Let's see how long I last before I sell. I'm not saying it's not a nice phone. I have zero tolerance for bloat and ads.
[Verizon Galaxy Note 4 Q&A, Help & Troubleshooting] mitchell4500:
Cant you disable most of/if not all of the apps that are causing you a problem? Plus if ads are so terrible cant you use adblock? Sorry if it sounds like a sarcastic question - but Im serious. My note comes tomorrow or thursday so im nervous.
[Verizon Galaxy Note 4 Q&A, Help & Troubleshooting] AlbusAngelus:
Yes, well I've had issues in the past using adblock without root. Adguard seems to be doing the trick for now, but I'll have to pay to get rid of app ads. I'm going to play with debloater after work and see what results I get. Maybe there is still hope yet.
[Galaxy S6 Q&A, Help & Troubleshooting] Obagleyfreer:
Could someone please clarify 100% if these 2 models are identical enough to flash ROMs or kernels intended for either device on one another??
[Galaxy S6 Q&A, Help & Troubleshooting] roydok:
They have different radios thus they are not compatible.
[Galaxy S6 Q&A, Help & Troubleshooting] Obagleyfreer:
But customs ROMS don't effect radios......and I'm pretty sure a custom kernel doesn't flash radio either.....
[Galaxy S6 Q&A, Help & Troubleshooting] Dexter_prog:
can't one just flash the radio of 920i onto a 920F rom?
[Galaxy S6 Q&A, Help & Troubleshooting] GuestK0062:
Anyone know can i flash UK BTU firmware with Odin to debrand G920F that is branded on T-Mobile in Croatia, without triping Knox or losing warranty?

Current CSC is CRO, DHR.
[Galaxy S6 Q&A, Help & Troubleshooting] djshotty:
Bit light on the details as to why they're not compatible, don't you think? A properly researched and verbose explanation can help many others, not just one person!

As far as my understanding of the hardwares in both the 920/925F and 920/925I devices, they are indeed identical. Only difference between both variants is firmware, and how the SoC's LTE processor on each device can connect to different mobile service provider network bandwidths (on GPRS, EDGE, UMTS, HSDPA, HSUPA, HSPA+, LTE, LTE-A). According to the spec. sheets on pdadb.net, there is only a small discrepancy with what mobile bandwidths each device can connect to which the other cannot, as follows:

920/925(F) - can connect to LTE800 (B20)

920/925(I) - can connect to UMTS1700/2100 (B4), LTE700 (B28)

BOTH devices are also capable of communicating on the following bandwidths:

GSM850, GSM900, GSM1800, GSM1900, UMTS850 (B5), UMTS900 (B8), UMTS1900 (B2), UMTS2100 (B1), LTE2100 (B1), LTE700 (B17), LTE850 (B5), LTE1700/2100 (B4), LTE1800 (B3), LTE2600 (B7), LTE1900 (B2), LTE800 (B18), LTE900 (B8), LTE700 (B12), LTE800 (B26), LTE800 (B19)

These differences lead me to surmise that the stock OEM firmware for each device has different modem.bin files, ie: the files which tell the LTE chip how to communicate on certain bandwidths. Why would Samsung build two devices that are identical in every way, except for a very small section of the very same Exynos 7420 SoC? This leads me to believe that all a 920/925I user need do to run a ROM cooked with 920/925F base code is flash in a 920/925I modem once they're up and running, and the 'radio' libraries will be updated for your 920/925I to work on the UMTS1700/2100 (B4) and LTE700 (B28) bandwidths. Only way you'll know for sure is to try that solution - which has worked for me on my 920I - because everything about each stock firmware is pretty much the same except for region specific bloatware and Country Sales Codes that control how the device connects to the MSP's in it's home region.

Only thing to be careful of? DO NOT put a 920 ROM on a 925, or vice versa!

If you would like to see what bandwidths your exact model variant SM-G920(?) runs on out-of-the-box, then visit SamMobile's thread on the subject here:

Hope that helps...
[Galaxy S6 Q&A, Help & Troubleshooting] Dexter_prog:
so basically what I asked is correct. We, the users of "i" variants, can flash an F rom + and I modem?
[Galaxy S6 Q&A, Help & Troubleshooting] Rekan_:
You can, but do not untick/tick any other options in Odin incase it can damage your knox status. This will not void knox since you are flashing official stock ROM
[Galaxy S6 Q&A, Help & Troubleshooting] GuestK0062:
Thanks, i did it and everything went fine, Knox is still 0x0. :D. I flashed custom ROMs many times but never knew that flashing official FW with Odin wouldn't trip Knox.
[Galaxy S6 Q&A, Help & Troubleshooting] djshotty:
If the bandwidth your mobile network provider broadcasts on is supported by BOTH devices, go right ahead. Thing is, the most important thing to check with putting one variant ROM on another variant is the chipsets. Without jumping around like I did yesterday and comparing all the variants, I can't be too sure if all 920's run the same Exynos 7420 SoC. This means that if Model A and Model B don't have the same chipsets then DON'T flash the other ROM. I already knew that the 920/925F and 920/925I share the same internals, but can't be certain about other models.

As for running ROMs between 'F' and 'I'? Just make sure if you've got an 'F' and want to flash in an 'I' 'ROM, your device may not work on the the LTE800 (B20) band. If you have an 'I' and want to run an 'F' ROM, check to see if your mobile network isn't UMTS1700/2100 (B4) or LTE700 (B28), because you may have difficulty connecting to it.

Don't concern yourself too much with tripping Knox and 'rooting' your phone. The debate has been going for a few years now, so I won't go into it here except to say unless you have the device on a service contract with your provider, Knox isn't exactly needed for the thing to run smoothly. Then, if you don't expressly need the feature for your work or business, you can rid yourself of what is essentially a bottleneck to you getting the best out of your device. I rooted my 920I the very day I bought it outright brand new back in May last year, and haven't had a single hardware related fault with it since. If you look after it, make wise choices about ROMs and do your research before making firmware changes, you should never need warranty repair inside the first 12 months of ownership - therefore making the decision to 'trip' a wise move.

Back to swapping ROMs, there is of course a workaround to any discrepancies with service provider bandwidth support. You will need to extract the modem.bin file from the stock firmware for your exact model variant in order to make your device connect to your provider. Pretty simple task really, and the fastest way to download stock firmwares is with the brilliant SamFirm tool. Visit the awesome zxz0O0's thread for more details…

http://xdaforums.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647

Just be careful doing the modem.bin swap. From what I've read, you have to use the same firmware revision modem.bin as the ROM you've flashed in, ie: 5.1.1 has to go into 5.1.1, something to do with RIL libraries compatibility. Me? I'm hoping to put MM on my 920I but until I find a model that's got an official 6.0.1 stock release which includes support for LTE700(28), I'm reticent to try it as I can't afford to brick my phone if the experiment fails.

I will leave then by asking if anyone out there tries to slot a 5.1.1 modem.bin into a 6.0.1 stock and it works, could they let us over at the Australian 920/925I Help thread know?

Cheers, and I hope I've been of some assistance to you...
[XDA Assist] Tazzypillar:
There doesn't seem to be any sort of thread about this. Maybe there's just extremely few SGH-I257 users but they really seem to be left in the lurch with regards to ROM support.

I saw reports that SGH-I257 (the AT&T variant of the Galaxy S4 Mini) could be flashed with the I9195 variant's ROMS, but I tried doing so and it didn't work.

I just want a solid answer as to where to go next, I'm kind of surprised this isn't something addressed in most Q&A sections for this phone. Is there some big Q&A thread for newbies that I've missed? Can anyone help?

Thank you for your time and sorry for the trouble,

[Moto G 2015 Q&A, Help & Troubleshooting] Rarscaryfrosty:
Can anyone confirm how quickly their phones charge? Using the stock charger that came in the box, I was getting an estimate of 3.5 hours until full from 29%. Granted the stock charger charges at 550mah. Has anyone tried a 2.1amp charger?
[Moto G 2015 Q&A, Help & Troubleshooting] mykenyc:
On my old nexus 6 fast charger it was 2 to 2.3 h/m

(edit) literally the only thing I hate about this phone is the charging. Going to just charge it at night I been tinkering with it to much.
[Moto G 2015 Q&A, Help & Troubleshooting] Rarscaryfrosty:
What h/m stand for? Sorry if it's a silly question, I've just never seen this abbreviation used before when it comes to batteries.

[AT&T LG G4] kazak1911:
I recently got into this green spot issue like everyone else. Planning to install whole bunch of AT&T stuffs to bring it back for replacement. However i found a fix for this. Dont know if this is temporary or permanent. Gotta wait and see. But at least it works on my phone and it may help the others too. Please dont yell if it fails on your device.

I went to Settings --> Apps ---> All ---> Camera ---> clearing data and cache. Reboot the phone and voila!! everything is FINE FINE FINE!!.

My phone is original AT&T H810 10g, flashed to H810PR 10A and rooted.
[AT&T LG G4] a40dayflud818:
I know this has been an ongoing problem so I say good job and keep us posted.
[AT&T LG G4] faizalotai:
Can you test a bit..check white balance, turn to manual and auto..does the green spot occur?
[AT&T LG G4] kazak1911:
REPORTS:

As of now, after 4-5 hrs of use. The green spot seem to come back. I cleared data again, come back to Camera, it's still there for 2 seconds then disappear. Try tweaking the manual modes, it come back on and instantly disappear and never come back again. taking like 10 photos in different settings, angles, corners, lights. I dont see it again. I know it is still there. This is not a 100% fix. But it doesnt hurt to try. At least to me, there is a way to get it working when needed.
[AT&T LG G4] bobimbap:
Updated: the green spot appear everytime i walk outdoor under the sun. Indoor, low lights are fine. So if the light is too bright. It will appear
[AT&T LG G4] faizalotai:
Here's mine now..lol...obviously its a hardware issue.getting new one
[AT&T LG G4] a40dayflud818:
To those having the green spot issue, how long did you have the phone before it started to appear?
[AT&T LG G4] bobimbap:
Mine is after a day or 2. I dont know. Got the phone and flash H810PR right away
[AT&T LG G4] soulysephiroth:
Didn't you switch in international rom too?
[AT&T LG G4] bobimbap:
Yes, i switch to that H810PR
[AT&T LG G4] a40dayflud818:
I just noticed today I'm getting the green spot as well. I am also on the H810PR. Has anyone seen/heard of a fix for this or should I revert back to the original H810e and exchange the phone?
[AT&T LG G4] soulysephiroth:
I don't believe you can revert. If you can let us know how it goes.

---------- Post added at 07:21 PM ---------- Previous post was at 07:20 PM ----------

I believe it's the rom.
[AT&T LG G4] kazak1911:
i'm pretty sure this is the ROM issue. Because my phone worked fine before flashing
[AT&T LG G4] FallingDanger:
Try to restore your phone software. Maybe it will help
[AT&T LG G4] informpage:
I also developed the green issue after going to the PR rooted rom. We likely won't get any further updates along this path - is everyone just living with it?
[AT&T LG G4] faizalotai:
If its related to software issue maybe we gonna have a poll within PR users that whose have and not having these green spot..but before these PR kdz was released, we've already seen some users having the same issue..

I guess its affected mostly in 1st batch devices
[AT&T LG G4] bobimbap:
I got the green issue right after flashing PR. Im travelling out of the country this week. I will have a pro technician check it out whether it is software or hardware related and report to you guys later. If it is a software issue, i will try to upload a stock firmware if i can buy it from them. I talked to a guy earlier this morning, he says he can figure out what the problem is when i bring the phone to him. Worst case scenerio, he will flash it back to stock at&t. Their stores has the official LG tools to do it.
[AT&T LG G4] soulysephiroth:
I replaced out my camera and both the camera flash and sensors and the greenspot was there again.
[AT&T LG G4] bobimbap:
So it is the PR rom that caused it?
[AT&T LG G4] soulysephiroth:
The camera was fine for while. But the moment I started using it again it came back. I had no problems with my ois and flash making noise/humming/vibrating till after I switched.
[AT&T LG G4] hlb3:
Mine just starred doing it now.

Anybody have any issue exchanging their phone with the PR version of the the software on it?
[AT&T LG G4] a40dayflud818:
I'm actually exchanging mine for the Note 4. The AT&T person I spoke to was actually extremely helpful. Since I'm within my 14 days of purchasing the phone, he said it didn't really matter what was wrong with the phone. I figure I'll just put the original H810e back on.
[AT&T LG G4] bobimbap:
Yay so many people share the same problem. It makes me feel better knowing that it is just a software issue.
[AT&T LG G4] :
Has anyone put the original 10e on the device yet?
[AT&T LG G4] a40dayflud818:
I'm about to give it a shot now. Any advice before I do? XD
[AT&T LG G4] :
Pray :p

---------- Post added at 06:06 PM ---------- Previous post was at 06:05 PM ----------

You're ina good spot to test it since your in your 14 try and let us know what happens.
[AT&T LG G4] hlb3:
I'm not in the 14 days unfortunately, I've had mine since June.

Good luck flashing the 10e, let us know the results.
[AT&T LG G4] a40dayflud818:
Should I still use the PR .kdz file? I am basically starting from scratch.
[AT&T LG G4] faizalotai:
Already replaced with new one...flashing 10b with PR seek and count, goes to bootloop..than blame OTA...

Doesn't know what'll come if stock image been flashed with stock seek and count
[AT&T LG G4] a40dayflud818:
LOL. Yeah I used the original H810e img and it is now stuck at the LG Bootup screen. Ah well. I took one for the team. :)
[AT&T LG G4] hlb3:
Well it was worth a shot.
[AT&T LG G4] bobimbap:
Is it possible to flash rooted H810 10g .img on PR since they are very familiar to each other? I'm too scared to try, has anyone tried yet?
[AT&T LG G4] faizalotai:
It will comes to bootloop..but you can try as long as PR image is in your internal storage for recovery

Means you keep both image stock 10g and PR..just make sure which one to flash

and you're using which flashing code??
[AT&T LG G4] CAG-man:
This is definitely software related. I noticed that when I got my images on my computer the JPG images had the green spot and the counterpart raw (DNG) files did not and were perfect. This is definitely an issue with the image processor. I'm going to try to take the camera and libraries from the AT&T version and try them on the PR image. Assuming I can located all the files.
[AT&T LG G4] bobimbap:
At last, someone with knowledge stood up and save us. Please keep us informed
[AT&T LG G4] keeper22:
Count me in as someone with the green spot issue on the PR Image. I tried using another camera app (Cameringo+) and same results.
[AT&T LG G4] :
Sheesh If you can find them let me know....I'm about to brick my devices to send it in for repair LOL and i just saw that post.
[AT&T LG G4] bobloadmire:
I'm on the PR rom for about a week now, with no camera issues, just as a data point.
[AT&T LG G4] informpage:
I only see it in sunlight. Indoors I don't see it. Try taking pictures outside.
[AT&T LG G4] CAG-man:
I've tried the various libraries from the AT&T rom. I'm wondering if a setting gets messed up in a data file for the camera... Any thoughts where to find those?

Edit: Thinking of the fact the issue is noticed in other camera apps makes me realize it is elsewhere in the firmware. Unless there are basic image processing libraries I am unaware of.

Remember, the green spot is not present in the raw (DNG) files. So not a hardware issue. Just in the image processing. Possibly a JPG library somewhere.
[AT&T LG G4] :
I honestly have no idea wheere they would be. I don't even have my G4 its on way to the warehouse for "repairs." I'm curious if anyone's ATT phone will get it without being on PR.
[AT&T LG G4] keeper22:
Just ran a few tests and Cameringo+ shows the green spot significantly less than the stock app. Had anyone else had luck with any other apps (at least until we find a fix)?
[AT&T LG G4] faizalotai:
Stock kdz is coming...thanks to @bobimbap

It will fix these green issue in our camera
[AT&T LG G4] :
Your ****ting me... Well to late to get my phone back now. How did he get the stock kdz?
[AT&T LG G4] bobimbap:
I am having a trouble trying to upload. To hell with google drive. Don't know what's going on. I don't know it's my internet connection or the server having a problem. We don't have a stable connection in this country.

Well, LG service center in VN has it. And it's not hard to buy it from them. Nothing you can't buy in vietnam

[AT&T LG G4] keeper22:

[AT&T LG G4] hyelton:
I have offered you ftp access to upload it to my server. Bad connection or not you should be able to upload it via ftp.

Also it cannot be a kdz. There's never been an AT&T kdz. Only TOT
[AT&T LG G4] CAG-man:
What does that have to do with the green spot?
[AT&T LG G4] hyelton:
Was just quoting the post.
[AT&T LG G4] keeper22:
With out the KDZ are we out of luck fixing the green spot?
[AT&T LG G4] CAG-man:
I'm still experimenting. But I will admit it is a slow go based on whatever time I have from day to day. I'm working on several projects.

What I have done was try the camera apk and libraries from the AT&T rom. I have since been looking through every nook and cranny trying to find possible related libraries to try.

Worse case I may attempt to decompile and see what code differences exist. Attempt to decompile.... Is it possible with LG apps? I'm still learning the LG ecosystem and somethings could be harder. I had came from Samsung which was very easy to decompile and make adjustments.
[AT&T LG G4] bobloadmire:
i don't get it indoors or outdoors
[AT&T LG G4] diedemus:
I notice it more in high contrast shots, like with a dark subject and a light background.
[AT&T LG G4] :
You can do what I did, either wait for some miracle software file to come up, cag to fix, or brick the device and send it in for a repair.
[AT&T LG G4] CAG-man:
So far the outlook isn't so good for me. I'm not giving up. But I'm running out of options.
[AT&T LG G4] joshuadjohnson22:
what if you use this with a stock image and see if it will let you flash. Naturally you will have to get the image file from someone with stock or maybe extract it yourself. Wait would it work with the rooted file from here?
[AT&T LG G4] hlb3:
That's what I ended up doing. I'm not even going to attempt to root this one until there is a way to restore it to ATT firmware if something goes wrong, or until a safer root method comes along.
[AT&T LG G4] faizalotai:
can you try this out with build.prop

ro.hwui.texture_cache_size=72

by default PR cache was set to 144
[AT&T LG G4] joshuadjohnson22:
root was easy, as long as you follow the guide you wont brick. But to be sure make sure you just do a system.img backup and leave it on your internal storage. If you do brick somehow all you have to do is boot to download mode and ADB that system image back and you will be back up and working. Most people forget this step and if they bootloop they are screwed and end up with PR

Make sure you have the stock rooted image for your software version and you are good to go. For example my is 81010e
[AT&T LG G4] phineous:
For some reason the hwui settings all appear twice. I made that change so both are 72, but still get the green spot in bright light.
[AT&T LG G4] faizalotai:
It doesn't work eh..:eek:
[AT&T LG G4] phineous:
After clearing the cache it wasn't there for a moment, but it came back.
[AT&T LG G4] faizalotai:
If someone can up recovery from att stock from E or G and flash to PR rom based via flash fire..that would save a lot of time..lol

either way this is just try and error... as long as PR kdz available if something wrong happened
[AT&T LG G4] joshuadjohnson22:
It will fail to flash the recovery because it is a locked bootloader. You will brick for sure. If we could do that we would be able to mod it for twrp but it doesn't work

Edit: Btw I mean hard brick that you probably won't be able to recover from

This is how I bricked my phone tonight so heed the warning and wait for a better option.
[AT&T LG G4] phineous:
Here's something interesting I just noticed; I was taking pictures with the LG camera app and of course was dealing with the green spot. I cleared data on the app, but this time it didn't help. I saw camscanner pro installed and thought to open it. Guess what, the green spot went away in camscanner! It was there for a second, but then disappeared.

Camscanner seems to take a pretty good photo. There's some extra steps to get it saved so it isn't the best solution.
[AT&T LG G4] :
LG sent out my repaired device yesterday, lets hope they replaced mine.
[AT&T LG G4] phineous:
I just tried camScanner in bright sunlight and the green spot comes back. So it seems the green spot appears less often in camScanner indoors but outside is the same as the LG camera.

---------- Post added at 06:26 PM ---------- Previous post was at 06:22 PM ----------

Just to be clear, let me sum up what I think you've done. You have an AT&T H 810 that was flashed to the Puerto Rican rom. You bricked it and sent it in for repair. Is that right?

Please let us know what rom and version you get back from LG.

Thanks!
[AT&T LG G4] :
Oh forsure will do.

I had a rooted 810 Rom, I messed up my messaging and tried to factory reset, it made me go into an setup loop, so I flashed PR. After that my camera tanked, and I then flashed the rooted 810 image onto my 810pr rom. So that bootloop bricked. Heres hoping I get a full different device back.
[AT&T LG G4] user787:
Will try that before trying the new PR version H1010A_04
[AT&T LG G4] joshuadjohnson22:
I hope someone on PR can try this out and report if this fixes the green spot issue and the touch issue. If it does it would be worth flashing.
[AT&T LG G4] kazak1911:
if you are currently on PR 02, keep it the way it is. Its not worth updating. Nothing new or change. Save you the hassle of setting your phone up over again

[AT&T LG G4] joshuadjohnson22:
Yes but as I also stated in that thread we won't know unless someone without the green issue flashed it. We do not have an example of someone who flashed their phone back to stock to confirm it will remove the green issue. It has been said that it could be that the pr software may have caused a hardware issue. So if the first PR created hardware damage a software update won't fix it, you would need to replace the hardware. One user said he replaced the hardware and the green spot went away for a bit but eventually returned. So next person who bricks there device should flash this new one and report to us if it has been resolved. ☺
