Hi, I'm from India and have a GT-I9500 which has been running flawlessly for the past 1 year on BSNL service right up to OS version 4.4.2 firmware vers. I9500XXUFNE4. Since then I upgraded the firmware twice to I9500XXUFNG1 and subsequently to I9500XXUFNI2. Midway while using firmware I9500XUFNG1 in rooted version, I started noticing that my phone data would run normally for a while and then suddenly the data connectivity would drop from H+ mode to 3G but would not return to H+ even though I know that I am in an area that has consistently strong H+ signal. The only option to get H+ mode back was to go to Settings/More networks/Mobile networks/Network mode/ and change the setting to WCDMA only mode for two minutes and then switch back to WCDMA/GSM(autoconnect), then the phone would get H+ service back again for a few hours. I thought that it might have been some problem caused by rooting, so when the latest firmware (I9500XXUFNI2) was released this month I upgraded the firmware but since I lost root on upgrade, I did not root the phone, fearing the problem will come back since I thought root was causing it.
Now in stock firmware running on I9500XXUFNI2 I am still getting the same problem of the phone dropping to 3G mode from H+ and not reverting back ( the speed is not even 2G. Just the 3G icon shows it - data packets hardly get transferred) and I can rectify it only by switching to WCDMA mode and back to autoconnect, as previously stated.
I checked online for solutions, but I don't seem to see anyone facing such an issue.
I thought it could be a service provider problem, so I used SIMs from Idea and Airtel as well, but while using those networks also, the same problem persists, so I have deduced it is a problem pertaining to the phone only. Not sure if it is a hardware malfunction or firmware based.
Does anybody else from India running the latest firmware for GT-I9500 have similar problems, and is there a solution?
Thanks.

The problem is with the modem firmware. Change it back to the original or get a kernel.

Thank you, Devilslasher. Could you please link me to a thread where they have listed the original modem firmware? I did a search under the Samsung S4 subsection on xda but could not find any thread where modems/radios for Indian version was hosted.
Thanks in advance.
Hey guys, hopefully you can help me get my S5 back on track.
KLTEUSC G900R4
The story goes:
I've been running CM13. Flashed a nightly, I notice my phone hasn't locked 4G basically all day. 3G only.
So I Odin back to stock using the latest firmware. Phone is still stuck in 3G. Phone does an OTA update to CPF2 baseband version. Still no 4G.
Took the phone to USC store, they provided me with a new SIM. Nothing changed.
I took a trip out of my home area, about 100 miles away I got 4G, but i had no network connection? The phone displayed 4G but i could not connect to any internet. It then dropped down to 3G shortly after and I was able to access data again.
Since then I've flashed back to CM13 (snapshot august 20th release) since if I'm going to be stuck in 3G forever, it might as well be on a ROM that I like.
Please help!
Thanks,
Jeremy.
Bump. Still no LTE.
If I reboot the device, the phone locks LTE for a few seconds, with network connectivity, but then quickly loses it and drops back to 3G. If I leave the phone in LTE preferred, it will run in 3G for most of the time, but occasionally totally lose data (I'm assuming its trying to connect to LTE) then go back to 3G.
Any Ideas?
flash the stock tar.md5 in Odin, reflash TWRP, boot it up fully, boot into recovery, make a NAND, reflash your ROM. Sounds like something got screwed up in the radio firmware
Will that still work even though I can't get 4G when i'm on the stock rom?
$50 reward to whoever can successfully restore 4G LTE to my phone. I've been living on 3G for 6 months and its starting to get to me.
I've been on Lineage OS with the same results. There was a firmware update, so I flashed it through Odin, and ran the stock rom/firmware for about 3 days with the same results. No 4G. Called up the US Cell Tech guys and they were going to check everything over on their end.
The last go round, I repartitioned the phone, did NandEraseAll, and EFS clear.
Any ideas?
Hi all,
Is it possible flash 870DS TWN firmware to my IND 870DS?
If yes, please advise what to do..
Many thanks!!
Update:
Please take your own risk to flash your H870DS
I've solved the problem of flashing HK rom which I following the link as below:
Finally I got VoLTE now and so far working fine

HKG 10C rom

*i flashed my Indian H870DS from 10C_IND_XX to HKG_10C_DS2_YT
Anyone know what's the meaning of DS2_YT?
Thanks a lot
Strange i download the hk version to.H870DS10c_00_OPEN_HK_DS_OP_0426. I dont see DS2?
You have any idea if it got netherlands language? Otherwise it's useless for me to flash
I would like to flash the Hong Kong over the Taiwan version.maybe it get faster upcoming updates.
Failing to flash
Hi,
I think I have bricked my phone. I received a H870DS witn TWN rom and decided to flash a CIS rom, so I followed the guide referred in this thread.
The procedure seems to happen happily but fail at some point with a nice error : LGUP 0x2BC, Invalid command response code = 0x80000202. At this point I can restart the process.
The phone is apparently only able to boot in Firmware Update mode (or am I missing something ?) What are my options to try to resolve the issue...?
Note: the error message is displayed usually after 50% in the upgrade process. It always happens somehow when the phone stops to display the COMXX port in green as well as the blue progress bar (as if it has encountered an error while flashing and restarted, I saw briefly some red text displayed at the bottom)
Any ideas ?
Thank you.
Did you flash the dual sim version? Otherwise you could brick.
For example i got the lg common.dll file and the hk-twn rom in folder that could be flashed with lgup to H870DS..
i once bricked my device with accident to debloat and reflashed twn rom.Afterwards it could start to bootloop and you will have to try to get in recovery to reset and data and afterwards it could start up just fine.

Yes I flashed a DS rom, this is the one I tried to flash : H870DS10d_00_OPEN_CIS_DS_OP_0418.kdz
Anyway, I tried one more time the HK one (same as yours) and this time it completed (I tried first the CIS, it failed, then I tried the HK and it failed, I uninstalled and reinstalled everything on the PC, force restarted the phone, tried the CIS and it failed again, tried the HK and it passed...)
I guess I will stop messing with it, not sure if flashing the CIS rom will give something more appropriate to the actual region the phone will be used : France. The two things I noticed are : country issues with LG Smart World (but who cares) and the phone doesn't pick up my 5GHz ac Wifi (channel 36 used) whereas it sees the 2.4GHz just fine. I have not tried to put a SIM in this baby yet, so maybe there will be some surprise here as well.
Great you could fix it Maybe the cause of a corrupt install is from what i catch up,if you flashed a rom with lgup you should reinstall it again when you would flash a other rom. I did not flash the HK rom because i dont know what will happen with future OTA if it will update or not if it get netherlands language.most of europe got that problem,lg smartworld i debloated because it connect from a korean server.im fine with twn rom
Good luck with it
Did you use Uppercut? I did, and flashing CIS OPEN went flawlessly. Got less bloat, correctly shown ststusbar icons and better battery life. Living in Sweden.

No I have not. Only LGUP with the dll extracted from the kdz file...
I have not tried again to flash it. Where have you downloaded the CIS ROM ?
I'm not sure I'll flash it again. My only concerns was for the Wifi (I can't see my 5GHz Wifi network on the LG whereas every other AC devices can...)
What do you mean with "correctly show statusbar icons" ? The icons for the cellular network (3G 4G etc...) or is it something else ?
I did try CIS rom (v10d-global-com)over my TWN (v10c-twn-xx) and lg bridge was a problem to identify. Instead of h870ds it identify as g6 and udate was v10c only while CIS got v10d also april patch installed. While i try to recover tru bridge it got twn again. So i keept original TWN

5GHz wifi will be enabled after you put in a simcard. I don't know why but that is the way to activate 5GHz.

They're all found here: http://downloads.codefi.re/autoprime/LG/LG_G6/H870DS
I have no issues with 5 GHz networks.
On the HK firmware I had double 4G icons when not connected to WiFi. One on it's own and one inside the signal bar icon. Not a deal breaker, but annoying. On CIS OPEN I'm getting an LTE icon next to the signal bars, and nothing else. The reception itself is also better now.

No, no one does as of yet, as far as I'm concerned. We've yet to get cold, hard evidence that there's an anctual July update rolling out for the H870DS.

Incredible ! Indeed, I put my SIM card in it, at first nothing came up, but when I disabled and enabled the Wifi, then it found my 5GHz network...
After shutting down the phone, getting out the SIM, once rebooted it still recognize and connects to the 5GHz Wifi network, so really putting the SIM does activate something (some things) regarding Wifi (and who knows else)

Ok I see what you mean. Actually I do like the double network id, this way I always know the kind of cellular network you are connected to.
So I'll leave it on the HK rom, as this is a present for a birthday on august 1, I better not break it . As it is I can't see any differences regarding cell reception or performance with my Samsung. It's really a nice phone (I bought a H870DS only because it is the only way to get a blue one with a black front)

I didn't compare dBm before and after flashing the 10d. It's the overall perception when actually using the phone that tells me that the reception has improved.

I have latest cis firmware over Asian Sea10c...but I can't receive 4g+..only 4g...someone encounter this?
So I've got the TWN model with the latest update where Volte is supposed to be supported however there is nothing in the settings or elsewhere. D/L and install latest CIS and have major issues with reception on SIM 2 (I think it was 2g only) and no volte settings within the menus and it's supposed to have them. Reinstall again from clean boot and still no volte and reception issues. Has anyone got the HK version running on a TWN model with volte etc? Or am I doing something wrong in the process of cross flashing?
Now I have tried cross flashing CIS, HK and SIN and the results are not good. I keep getting the update 10f, 10e with global-com firmware. It does update however each one has the issue of the second sim going to 2G and not 3G and no Volte settings in any of them. I then go back to TWN and its all okay apart from not having the Volte settings. Yes the upgrade is with a clean boot and through LGUP. The strange thing I don't get is the Refurb option but as I led to believe as long as you reset it should be okay to select Upgrade. It appears that the region settings cannot be or altered through this process. One thing I did notice with Global-Com is that there are settings for Mirrorlink so you use LG Drive if you wish however this is not as important as the twin sim and volte for me. Any one any other suggestions on this topic?
I have a stock Verizon G950U (on Selectel prepaid but that shouldn't be an issue) and used the PC software to install the latest update NRD90M.G950USQS2BQL1
Immediately following the reboot I have not have service since. My sim works in other phones, took S8 to Selectel store and they confirmed working Sim and said it was a device issue. I have factory reset and even restored the firmware with the software again. I don't get a ton of service in my rural area but was able to activate an old S3 that I had lying around. The Selectel store is also in a larger city with plenty of service.
The radio is on as it shows bars, scans and shows networks, but absolutely will not register manually or automatically.
My limited knowledge and searching says that I cannot directly downgrade the firmware to an older working version. I've rooted older devices but last I played with it KNOX and the risks of bricking are getting ridiculous unless someone can specifically state otherwise for this device and link me to videos and direct download links.
Thanks in advance, I'm pulling my hair out. Short of rooting or waiting for the next update to hopefully fix it I don't know what to do.

Ok so its not a corrupt EFS issue. have you gone into netwrok and switch to global or anything....
Does it show your phone number in the info as well That will tell if its reading sim or not
It does show my number from sim after booting up without a sim and then inserting. I don't see any global settings. Again from the update no settings changed, since then I've wiped to factory settings numerous times.
I can't find a fricken stock rom file anywhere for crying out loud, just loads of register spam sites.
I think I'm downloading an Oreo 8.0 rom but can I downgrade later and again where's the dam file?

Don't worry about Knox, it's not possible to trip it on a 950u
Tried flashing to BQK5 with moderate success. Passed with Odin (which csc file should I use?) but on reboot it stalled at 32% when installing. Rebooted and after flash screen updated android and showed BQK5 but all my data and apps were there so i likely screwed something up. Installed sim card and momentarily showed 4g and appeared to register but at reboot did the same crap with no service.
Called Samsung prior to flashing and no surprise that was a colossal waste of time. I'm not paying them $200+ to fix an unrelated issue with the back glass that cracked with a case on and phone has never been dropped. They did say that they're partnered with best buy but that's two hours of driving for me...I'd fix the back glass myself and try to get them to give me a new phone if it came to it.
Verizon software shows an update now so I'll let it download (again...takes all night for some stupid reason) and vainly let it flash to current version.
I think I found the Oreo 'final' update so might try that...looks like it installs off an sd card if I can find an old one.
