Hey everyone,
After I did the radio update (after doing the full root) my 4g was really messed up. The 4g would just not stay on and kept going out and then coming back every few secs. I tried reflashing the radio and yes I also formatted the cache right after and going back to the old radio. Then I tired going back to stock and it was fixed but when I did the full root again without the radio update after, well the 4g was back to crap. I even tried a custom rom after the root and still no go. So after doing many tests I found out that the firmware for the wifi is different from stock and full root. I found this out by going to ##DEBUG# then WiMAX Engineering...The full root had 20100401 (im guessing its the date of the firmware) and the stock had 20100423. So after more testing this is what worked for me.
1. I took the image file from the first part of the root (PC36IMG.zip)
2. Then I extracted android-info.txt and wimax_25043_R04.img
3. After that I made a new zip file with those two file from above and named the zip "PC36IMG" (without the quotes).
4. Then I put the PC36IMG.zip on the root of the SD card of the evo.
5. Then I booted up to the bootloader (u know the screen with the androids skating). Then I did the update and reboot.
After that my 4g was working without getting droped every 5 secs
If someone else tries this please let me know so I know that I didn't just get lucky.
P.S. IM NOT RESPONSIBLE IF ANYTHING BAD HAPPENS (it shouldn't but hey **** happens lol)
Enjoy your 4G back!

I have the same problem, but...this is a hell of a first post. Anybody wanna test this out.
If someone can post the files, I can test it. I'm at work right now and can't download files that big w/o being flagged.
you mind posting the update zip you created?

I don't think it has anything to do with the ROM.
If when you are connected to 4G you can access the internet, only suddenly 4G it drops for no reason and switch to 3G and then reconnects to 4G and goes on and on, below is the solution. if when you are connected to 4G you can not access the internet at all, the below wont fix it for you and it is probably a problem with your rom.
You will need your msl code to fix this, loop up in the forums to to obtain your msl code from Sprint:
hit ##DATA# > Edit mode.
Put in your msl code
Chose WIMAX
Scroll down to Wimax_Idle_Sleep
Change the value from 10 to 300.
Click menu, commit changes and restart the phone.
This fixed it for me and i never drop 4g (when in good coverage) again.
Basically Sprint has some STUPID setting that tells 4g to go into "sleep mode" of no data is passed on the 4g connection after 10 seconds which is essentially disconnecting 4g.
The problem is it goes into sleep mode (disconnecting), but then rescans and look for a 4G signal > reconnects to 4g and if no data will be passed in 10sec it will do the same again in an endless loop.
10sec to put a connection into sleep mode is really low so change it to 300sec.

This sounds like the same issue. I wonder if that file sets the sleep time? Just a guess. I had the same problem and this fixed it.
Here is the thread where I found it.
http://forum.xda-developers.com/showthread.php?t=704845&highlight=4g+sleep
Oh for me the wimax idle sleep time was always 10 even with the 20100401 firmware. The only thing that seemed different was the wimax scan attempt time. In 20100401 firmware it was 120 and in 20100423 firmware it was 1. So when I tried to change it in the older firmware it said I can only do 5 - 300. So I tried 5 and still no fix. The 4g still drops in and out. Here is file I used.
Tried your .zip. Not good. 4G is stuck on scanning and won't connect. I'll see if going back to the stock radio will fix it.
Oh that didn't even happen to me but I was already on the old radio. Try the old radio and remember to clear the cache. If it gets stuck then go to ##DATA# and check your wimax settings. Let me know how it goes.
Ran back through the Simpleroot process and got 4G back. Whew.
Nice! I wish I knew exactly what causes this problem but hey if it gets fixed then I don't care so much lol
is this zip already modified??
All that zip has is the wimax radio file to flash it but the file is old now. If your already on the latest radio then i would not use it because it may cause problems.
im stuck in "scanning"
You may need to reflash the radios and wimix. Are you on 2.2?
im on original 2.1 update1
I have the newest baseband tho... 2.12.00.07.28
I flashed this zip and phone is acting a little goofy
3G is in and out also!!
is it possible i may have to reflash the original RUU and start from there??
Why don't you try 2.2 maybe it will work after that.
after i just installed that zip im now getting DATA call failures error code 67.
Yea that should fix it or see if there is 2.2 RUU file out. Sorry I'm not home so my responds are very slow lol.
Hi everyone, I made something funny that worked today
Scenario is the phone has no IMEI, no BASEBAND, cant enter the service code *#*#197328640#*#*, can’t call and gives force close, and in short the phone is useless. HAHAHA lol.
The history of the phone is HARD BRICKED after my big brother flashed a kernel onto this phone after upgrading to 4.0.4. he wiped user data and along with the EMMC file, it became unresponsive and doesn’t turn on anymore.
I had it recovered using MEDUSA box and after I got the BOOT/DOWNLOAD mode. I flashed a firmware with DXxx.xxx baseband. im so glad that the phone was completely working again, ALMOST hahaha. When I inserted my stupid SIM, it doesn’t want to pick up signal an found out that there is no BASEBAND version as I checked it on about phone, or dialing *#1234#
I have done some research and I knew that I is gonna be the RIFF box again that will fix this thing. What am I gonna do to a phone that doesn’t pick up signal at all. I flashed it over and over again even the MODEM alone but still no luck.
Things that I have done to have it work though with a wrong IMEI
1. Root the phone
2. Installed SGII repair
3. Backed up the efs folder (either using ROOTexplorer/the SGSII repair app)
4. Downloaded the EFS pro
5. Downloaded the .NET framework 4.0
I tried repairing the EFS using the GSII repair but still no good after reboot, and used the the EFS pro to repair it but still no good. After rebooting couple of times I don’t have signal.
Imma make this short now
1. Root your device using whatever method u can use
2. Install root explorer and copy EFS folder to your internal SD card then paste it somewhere on your computer. (name it as ORIGINAL EFS)
3. Now use the SGSII repair (download it in app market)
4. Use the repair method then back up the repaired EFS folder on save/restore option (REPAIRED by SGSII repair app)
5. Paste the .tar file to your PC/Laptop and extract it and name the EFS folder as repaired EFS folder
6. Use the EFS pro and click on format the EFS folder. (make sure before doing this, you have repaired the EFS and BACKED UP the repaired EFS using the SGSII app)
7. Connect your phone to your pc and mount the storage to your PC/Laptop
8. Copy the extracted file you have backed up on number 5 (using winrar)
9. Copy the content of the extracted repaired EFS by the SGSII repair app to the ROOT EFS folder of your phone.
10. Then click the Repair NV data / Attempt NV recovery
11. If that did not work just reboot the phone first and do the number 10
12. Reboot again the phone
13. Once rebooted the phone will then have the icon of w/out sim, has baseband, and once you inserted the sim it will then have coverage to your carrier
14. Do it with a little bit of luck
Enjoy your phone with wrong IMEI and the screenshots I have put on this thread are, after I have done everything but previously it doesn’t show the BASEBAND version and everything. but after i have done THESE steps, it suddenly displayed the baseband version and i had signal
I tried doing this but it has just gone with the no baseband version again
http://forum.xda-developers.com/showthread.php?t=1264021
These steps worked for me and I have a working phone with wrong IMEI.
Worked for me :highfive:
Any helpfull steps / posts / links that would completely recover the ORIGINAL IMEI would be gladly appreciated

A phone with wrong IMEI will be blocked in 2 days in my country
I accidentaly flashed in a i9100G ROM on my i9100 (regular one, no NFC and nothing extra), not even an unlocked one, and i lost all my phone thingys.
But i am a bit nerdie, so i searched for my problem here, and discovered that flashing an 9100G modem is a really bad idea, so i decided to flash an LP7 MODEM/RIL back and evrything went to normal (at least in my case)

better backing up your EFS folder to your SD card cause it contains a very important file...
I have this strange problem where sometimes my modem does not work after a clean flash. Usually just making sure the data network preference is set to LTE solves the issue, and after 10 min or less the phone picks up the band. But I've just done a clean flash teamUB 1/11 and its been 24 hours with no data connection. This same build worked fine for this same phone a week ago, but the 1/19 broke the phone so I had to do a clean wipe and go back to 1/11.
I've played with data roaming options in CDMA roaming mode, set to domestic roaming, national roaming. Still no data
Any advice?
This is for a 900P (sprint) - Note that I am on CREDO (uses Sprint network)
EDIT - FIXED YAY!!! FULL LTE WORKING GREAT!

The issue started when I was forced to wipe my system data and do a clean install in order to get the phone functional after boot loop from 1/19 update. so yes, I would assume that the modem built into the 1/11 update I rolled back to (clean install) contained the modem. But, as stated, the 1/11 build was working fine for me before, and not now.
Is there a way to just update the modem itself on this build/phone? I've been wondering about that and wanted to try it if possible.

There is no modem included in TeamUB's roms.
First thing's first, what model are you using? Go to signature settings and write your model there, this way whoever is helping you they will know what they're dealing with.

No need to say sorry man, just mean it makes it easier. Haha you're signature says 900O lol.
1 Install Samsung USB driver for mobile phones
2 Download the NE5 modem one click flasher here
3 Put your phone into download mode (Turn off the device, press Volume Down, Home and Power Buttons simultaneously, Once you see the warning message, release all buttons, Press Volume Up to enter download mode, Now your device should be in download mode)
4 Run the file from #2 and flash modem (if NE5 doesn't help try the other ones).
I don't think it's a modem problem though. IMO it's either the rom or the operator..

The NE5 throws a <OSM> MD5 hash value is invalid error. I flashed the ND2 version and no immediate data connection, but from past experience it can take a little while for the modem to sync. No idea what causes the delay, but everytime i flash a new rom it can take sometimes up to 30min before it gets a data connection. Been 15min no connection yet.
Couldnt find a mirror anywhere of that NE5 one click flasher. Know of any other hosts? i googled to no avail.

Update:
I have restored a old backup to kitkat, modem working fine, instant connection. Then I did a system wipe, clean flash to cyanogenmod 1/20 update released yesterday.....no modem. Restored backup again to kitkat, then did a dirty flash to 1/20 cyanogenmod.....no modem.
I think the issue is 5.0 itself. The issue is so random, I do not know how to troubleshoot it. I've installed maybe a dozen CM's so far, and its been a coin toss whether the modem works after install. Sometimes it syncs up after a few min, and sometimes never. its really strange because I had the modem working fine on TeamUB from late december, through 3 or 4 updates until 1/19 boot looped it. Now after that nothing has gotten the data back on other than restoring to kitkat.
When i did the clean install to cyanogenmod, on the startup process where it says 'waiting to activate cellular service' it gets stuck there and never activates the data.
Also, when trying to flash the NE5 tar md5 you linked to, I get md5 error! Binary is invalid. Im supposed to use AP, yes?
EDIT - Changed preferred network type to 3G and after a few reboots got data! Going to change back to LTE now and give it some time to see if i can get it to sync up.

No luck leaving it on LTE. When I switch back to 3g I can get a connection, LTE set in preferences I get no connection, not even 3g. I've been testing around the city and at my home, where I can always pickup a LTE connection from past experience.
It seems that the LTE protocol within 5.0 is buggy for my situation. If it works, it seems to work fine, but when it doesnt work, it never works. So its either glass is full or empty

There are two versions of labels in Odin. The "normal" says "phone" the one I don't like says "CP". You have the Odin I don't like lol, so yours says "CP". That's where you put the modem. "AP" is for firmware/roms only.
Try these two modems, which I found on this page, NK4 for 4.4 while NKD is for 5.0.
Try Ktoosez kernel and also check your Apn settings, it's supposed to be optimised for CDMA phones and might help you.

Congrats! I'm glad it worked out Ktoonsez mentioned in the CM12 thread that his kernel was optimized for sprint/verizon phones in some way, don't remember what though :silly:
OK, *FIRST TIME POSTER HERE* so please excuse any unintentional ignorance of rules or etiquette.
I'm just super excited to get this phone working the way I like it, and it's all thanks to xda so I was moved to create an account to express my thanks AND hopefully help a few people back.
How? Well after reading through pretty much everything I could find on the N910S here and elsewhere, it seems that no-one (yet?) has been able to confirm a working mod that meets the following:
1. N910S Exynos Korean version
2. Some kind of custom English only ROM that removes the Korean characters from keypad and other network-apps
3. Removed bloatware
4. Easy-to-follow, how-to guide
Seems there were quite a few ppl who wanted the same thing so I just want to let you know what I did to get it working.
*PLEASE NOTE* Everything contained in this summary was found through over a week of tedious reading, research, trial & error. BUT in the end all the necessary information was contained, or linked to, in xda forums. It's just that all the relevant information and files were scattered over many different threads and topics. I'm just collating it all here to hopefully make it easier for the next person to find.
Background info: I'm technically competent but relatively new to phone modding - I've only rooted my HTC E8 before this to remove bloatware. This is my second project. I live in HK and started with a completely stock OEM Note4 N910SKSU2DPK2 after a factory reset. I then did the steps below in order (not including many failed attempts and re-starts, of course) These are just the broadstrokes of what I did, if you need to know how to do each step in detail then please search the forum. It's quite clear and there's no need for me to repeat it here anyway
As it's my first post and I'm in a rush to leave the house soon, I have not bothered with screenshots or links - I'm happy to provide if someone can tell me if the preferred method is link to the thread where the info was found, or you just want a link to the files I used. Again, they were all found through links in threads on xda anyway but I'll have to spend some time to find them again as I didn't bookmark them. Also, if you want the files someone will have to tell me how to upload them here. The filenames/packages are given in [brackets] so maybe you can just search for them?
0. Reminder to backup your phone and data first!
1. Root - was really easy using CF AutoRoot [CF-Auto-Root-trelteskt-trelteskt-smn910s] Just download to your PC and package includes Odin, which for first-timers is the official Samsung software used to flash to your phone.
2. Download:
- ClockWorkMod [n910s-cwm-recovery-6.0.5.1(1113).tar]
- SuperSU [SuperSU-v2.79-201612051815.zip]
- C Mod ROM [C_ROM_N910s.v2HNY.zip] (the site is Korean-based but google translate of the page was enough for a non-Korean like myself)
- N910S DPK2 modem file [N910S-20170114T050808Z.zip] The original thread had links to every modem variant they knew of, so should work with other S/L/K variants BUT of course I haven't tried them.
3. Copy files for SuperSU, CMod ROM, and DPK2 modem onto an external SD card and insert into your phone.
4. Put your phone into Download Mode (from power-off state, hold Vol Down + Home + Power)
5. Run Odin on your PC, connect phone. On Odin, click <AP> and select CWM file. Do not check or modify any other options. Click <Start> to flash CWM recovery to your phone.
6. Once it's done, disconnect from PC, and restart your phone into the new custom recovery mode (from power-off state, hold Vol Up + Home + Power)
7. Choose Install from zip and select the SuperSU file from your ext SD card. (I think this step may not be strictly necessary as it's part of CF AutoRoot, but SuperSU is always handy to have anyway)
8. Reboot into Recovery mode again (available in Advanced menu)
9. Install zip - now choose the CMod ROM file. Reboot into system and have a look around the new UI. It was at this stage that I noticed two things: my HK carrier SIM was not recognised, and as the ROM boasts some Note 5 features the Always On Display function would cause my Note 4 to not be able to wake up once the screen was turned off (manually or via time-out). I had to pull out the battery, restart phone, go straight into Settings -> Display and turn off the Always On Display functionality.
10. To fix the SIM card not recognised, reboot into Recovery Mode again and Install zip - choose the DPK2 modem file (or whichever version your phone's modem is). Restart phone, wait a few minutes and SIM should now work.
*ONE REMAINING ISSUE* Even tho my SIM is 4G/LTE, it seems to be connecting at HSUPA only. Could be reception, I'll check later. But I believe there's a way to select different LTE bands through secret codes or menu, not sure but I'll try that as well later and update if it works.
That's it - hope it helps! Thanks for reading, and don't forget I'm new to this AND a first time poster so be kind in comments/questions please

So by following steps in this thread https://forum.xda-developers.com/note-4/help/note-4-sm-n910s-sk-telecom-issues-t2929571/page2 for SKT, I was able to change to LTE Band 3 or 7 (which is what my sim provider offers) and get an LTE signal for data, BUT then I lose voice call functionality. If I choose Band 3 Preferred, it says band changed success, but just connects via HSUPA and I get voice, but no LTE (just like before, or if I choose Automatic)
Can anyone please help me figure this out? How can I get voice AND LTE? Many thanks in advance!
PS - also after I reflashed my modem.bin the baseband changed from N910SKSU2DPK2 to N910SKSU0DPK2. I don't know what this means nor if it has anything to do with the problem I've described above? Can anyone help to explain? Thanks...

Band 3 and 7 are supposed to stick with default settings. I tried it once during my trip to Malaysia and it worked flawlessly. Any chance you might want to contact your carrier?
The trick to switch from 4G-3G-4G works. ATT band 5 preferred

Have you tried switching to 3g only, then switching it back to 4g when available in your phone setting??
I had similar issue with 4g and apparently, this strangely simple trick solved my problem.
Anyway, I tried to download the ROM from the Achonapp but took me ages and I couldn't flash it either. May I know where you got the ROM from?

Tried your suggestion but now it shows No Service
*update* actually I think your "trick" works... After switching to 3G only, it wouldn't switch back to 4G and showed No Service. I rebooted the phone with a different sim and after a few minutes, it automatically connected to 4G AND I now have voice as well! So, all is working properly now and I'm a happy camper. Reboot with the original sim and still works and connects to 4G. So I think you're right it just needed to be "forced" to select 4G preferred. Thanks for the tip!
Yeah I got it from achonapp as well and it took a while - I think I left it going overnight. But the ROM did work for me. If anyone wants the file direct I'm happy to put it up on my google drive if it's not against forum rules etc.
But since then I've switched to miui8 which is also working pretty much flawlessly as daily ROM, but I haven't tested every single little feature of course. If you wanna try it - https://forum.xda-developers.com/showpost.php?p=70596588&postcount=797
I am having issues getting other rom's to work. I have flashed lineage to my sprint samsung galaxy s5. I have the twrp bootloader installed and thanks to skillsoft tool i was able to get it to actially stick. I did not like lineage primarily because it has issues with lte and my 64gig sd card ( my 16gig worked though despite being significantly slower) So i tried moar rom by downloading it doing a wipe and installing zip. I let it sit for 40 minutes but it stayed on the samsung screen. So i thought ok maybe its the rom, i downloaded aj's a8 2016 port v2 did a wipe and installed it as a zip, same thing. Is there an issue going from droid 7 to these other rom's?
OK, So i was wondering if this is just me. I dont see much mention about this problem browsing the threads. Course i could be missing it. So despite not really wanting to i brought my phone back to factory. The LTE connection came right back which was relieving i thought maybe i screwed something up royally. So i re-installed twrp and flashed ResurrectionRemix-M-v5.7.4-20161121-kltespr figuring maybe its something with the neugat based roms. I still cant get my phone to connect with lte. I switch it to lte prefered, nothing. Switch it to 3g and i can connect. Back to lte still nothing. I am clueless as to what might be going wrong other than maybe its the modem driver?
The factory rom i used was G900PVPU3BOK4_G900PSPT3BOK4_G900PVPU3BOK4_HOME.tar.md5
Any insight on this would be very welcomed.
Well I am a bit confused on this. I took the stock rom and extracted the NON-HLOS and modem bin files. ( thank you 7zip allowing fools like me with windows to do things linux is often used for ) from the stock marshmello rom which i downloaded and previously flashed to my phone and verified it connects with lte. I made a tar with both of them and flashed that via cp on odin and i still can only connect with 3g. I am really not sure whats going on with this.
Ok Turns out not knowing what i was doing basically created a LOT of extra work for me. I use a 3rd party mvno called tello which is great for low cost low usage customers like me. I finally stumbled upon this thread: https://forum.xda-developers.com/general/help/tello-apn-settings-t3409432
Added the tello apn and whala worked like magic, didnt even have to reboot. I had to do this with it set to global. For whatever reason when its set to lte i couldnt add and save a apn. Once i added the apn then switched to lte whala lte connection.
