[HOW-TO] Flash your at&t Tab to make calls + 1900+850 WCDMA - UPDATED

Please note that i am not responsible if you brick your Galaxy Tab.
This worked for me and i now have a Galaxy Tab, on At&t making calls + 3G data + 850/1900Mhz WCDMA enabled.
**please note you need to have a SIM card with a proper voice plan and DATA plan for this to work. do not try this with the prepaid card that came with the Tab.
1) Download the firmware P1000XWJJ4 from HERE (pass: samfirmware.com)
2) download the firmware P1000XXJK5 from HERE (pass: samfirmware.com)
3) download Odin 1.3 from HERE
4) download the modem_bell_i9000.zip file attached to his post and extract it.
A) put you tab into download mode and flash P1000XWJJ4 with P1_add_hidden.pit and repartition selected. The phone will reboot and will be in Russian.
B) Put the phone into download mode again. flash P1000XXJK5 with NO repartition and NO PIT file. the phone will reboot with the latest euro firmware in english.
C) finish the setup wizard, if you do not get DATA at this point (3G or EDGE) at this point go into APN settings and change the APN from "Broadband" to "wap.cingular"
D) Put the Tab into download mode and flash the attached modem.bin file (the one you extracted) by selecting the bin file under "phone" in Odin. NO repartition and NO PIT file.
E) At this point your phone will reboot and you should have 850/1900Mhz enabled and everything you should work just like the euro version of the Tab.
Done and done.
UPDATE: I found that at&t are disabling HSUPA on the Tab, thus using the at&t original modem will not be ideal. I found that the Bell Galaxy S 2.2 modem is the only modem i found so far that will give us 850/1900Mhz + HSUPA + voice calls.
Please flash this modem instead. it is attached.

Nice... How come we need to go to the Russian ROM first? Thanks again Clubtech.

Because it is the only real full flash firmware we currently have and that fixes the boot logo problem i had when i didn't do a full flash before.
XXJK5 is not a full flash, but incremental one so we have to flash twice.

Will this work with tmobile tab?

Wow you are a real genius , this tab just cameout today and u already found a way to make the voice work compared to the other post here about flashing their tmobile tab still scratching their butt trying to figure out how to make it work. Can you help us tmobile user to make our device working with voice and 3g? I got 3 more days to return it and get at&t.
Great instruction too! Your the man!

T-mobile are blocking the data plans by IMEI, so there is nothing we can do unless you want to fake your IMEI.
As long as the IMEI stays the same, even if you got 3G and voice to work, data will still be blocked on regular phone plan sim cards so there is no point really.
For blocking by IMEI T-mobile should see all their tabs returned as far as i care.

Could this work for Sprint?

No. These firmwares are only for GSM models.

so if i get a att tab do what you posted and unlock it then add my unlimited t mobile sim will i still be blocked?

It shouldn't be blocked (unless T-MO is blocking ALL Tab IMEI's, not just their own), but even so you'll be unable to use 3G, it'll be EDGE only, since the AT&T device won't support T-Mo's AWS frequencies.

What if i flash it using your instruction and insert my att sim card will it work?Thanks a million!

A small update.
So it appears that at&t have disabled HSUPA so the upload speeds are slow (it is capped around 386Kbps).
I tried flashing the Bell modem.bin. it kept the 850Mhz and disabled the upload cap but i could not longer make or receive calls.
Flashing back to the at&t modem back and i was able to make calls but the upload speed is again capped.
Thank-you at&t!!! for crippling my hardware!!
Anyone can post the modem from Rogers? that would be helpful to try.

On step a), it's really a 2 steps process right? Meaning
1. Download the pit file
2. Flash the PDA, Phone and CSC
according to general flashing instruction here http://www.samfirmware.com/P1000 how to flash.pdf ?
And when come the 2nd flash, skip the pit file and flash the other 3: PDA, Phone and CSC?
Thanks again.

Ok, Bell GT-P1000M is now flashed with JK5 and the AT&T Modem, and is fully voice and data functional on Telus (I manually unlocked it) in both 850 and 1900 bands.
Rock on.

Since the Rogers version is the same as AT&T, this should work on the Rogers galaxy tab too right?

European x10 unable to connect to Rogers after 2.3 update

Hey folks.
Not actually an x10 user myself, but someone I know with an x10 is having an issue.
he bought an unlocked x10 from europe, and has been using it with Rogers for a long time now.
After running the gingerbread update, he's lost the ability to connect to the towers. The APN settings have disappeared, I restored them, but he's still unable to connect. Tried manually selecting a network. On WCDMA only, nothing shows up. On GSM/WCDMA mode, the only option is 2G (Yes, there is good 3G service in the area). If I try and connect to 2G, it tries to register, then returns an error saying the SIM does not allow connections to this network. I tried with both my SIM and his, same result.
I did a quick check, and I see the x10 european model supports 900/1700/2100, but it obviously also supports 850/1900 considering he was connecting before the update.
My question, has the update changed the radio making the phone unable to recognize the 850/1900 HSPA bands? If so, is there a way to go back to Froyo without rooting/flashing a custom ROM?
Thanks for your help

crap, sorry, please move to Q&A. I thought I clicked QA, my apologies.

It doesn't also sorry the other bands, that's impossible.
The radio hardware is different.

hmm.. unless he's been on only 2G the entire time?
Still doesn't explain why he's unable to connect to 2G at the present though...

nope because you are only puting back on original Firmware, also just try SEUS to factory reset phone and reinstall firmware should kick it in to gear

[N910S] got it to work! Exynos Korean model, Eng-only custom ROM, no bloatware!

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

Update and question

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

Will an S7 Edge (T-Mobile) work on Verizon?

Hello all,
I want to switch to Verizon but I don't have a verizon sim to test my phone, I just got it unlocked through the unlock app. I've also read this post,

but there is no confirmation if he found a solution.
any feed back would help.

Well i live in Mexico, but i own a galaxy s7 edge from tmobile and to try nougat i installed first the Verizon version, and it work well, the only issue was to setting the data configuration, now i use the At&t nougat and everything still even more perfect (the verizon nougat have a lot of little bugs)

Using a Tmobile S7 Edge going to Verizon won't work cause of a few reasons.
1. TMOBILE S7 and S7 edge are not built for CDMA networks that uses certain bands and network. Along with the security of CDMA networks.
2. There is no band 13 on tmobiles S7 and S7 Edge. Even you were to unlock it.
But going from CDMA to GSM most phones work due most of the hardware and software is already built in the phone.

I can confirm this. Yes, your unlocked T-mobile S7/Edge will work with Verizon network if you flash the U firmware. I'm currently using my unlocked T-mobile S7 Edge with the U-firmware on the Verizon network. Voice, text, data work fine. No issues for me.

You can flash the stock Tmobile ROM or the U firmware. The only reason I got a new S7 when I jumped from big red was I had a huge scratch on my screen. I was running the U firmware when I went into tmobile and used the girls sim card from her phone to prove I could do it...

Don't know but I am on T-Mobile and I use alot from Verizon thread no issues so far

OK, so I have a question. I'm also trying to move from t-mobile to Verizon but I'm trying to keep my same phone. My phone is already paid off and i currently running t-mobile's SM-G935U over SM-G935T. But a couple of days ago i asked a friend to let me barrow his verizon sim card to test it out. But received a message saying "Invalid sim Card" "network locked SIM card inserted." Did i messed up something during the installation of the SM-G935U?

You need to UNLOCK your phone. It might be a Tmobile phone and running G935U software...but the sim is still locked to T-Mobile. Here is Tmobile unlock page information. you can request unlock in the T-mobile app or by calling T-Mobile....then it should see the Verizon sim and load up just fine once the phone itself is not locked to T-Mobile only sims. https://support.t-mobile.com/docs/DOC-1588
And for anyone else looking at this forum, There is no physical difference in hardware from a SM-G935T phone and a SM-G935U phone. Samsung actually made the hardware the same for all US Variants it is just the software that is different. And not that you would want too but you could load other carriers software on your phone if you wanted too(IE- running Verizon software on a SM-G935T, or ATT or SM-G935U (Stock Samsung Software) The only problem Running SM-G935U is they haven't upgraded the unlocked us phones to 7.0 yet. Where T-Mobile and other carriers already have nougat out.
The SM-G935U software however has all the US and even some Chinese LTE bandwidths enabled, and it also enabled the CDMA bandwidths to be used on the SM-G935 phones...hence why it will work with Verizon, Sprint, and even US Cellular if you can get them to put it on the account.*(I haven't dealt with US Cellular in years and with the new laws on moving phones from carrier to carrier in the US they might not have any issue with Bring your own phone to US Cellular anymore I do not know!)

Had you flash any ROM before via Odin?. If so, you will only need to download the verizon firmware (sammobile.com) and flash those files. if not > Open odin (Attached) load all the files accordingly (AP, BL, CP, CSC) in ODIN> put your phone download mode ( pressing fingerprint button + volume down + power) > connect phone to PC > Once all files are ready in ODIN hit start. You will get the success message and phone will boot.

Exit completely ODIN (make sure you run it as administrator), repeat the process and make sure all files are uploaded (AP takes a long time to upload) make sure to use the CSC file label as HOME_CSC. Try to flash again.

If you are going to use a verizon sim, you will need to have it unlocked. Firmware flash won't sim unlock/lock the phone.

Thanks for the quick reply. I thought I was gonna be waiting months. I got it tho. The home csc file wasn't working so I used the other one that reset the phone to stock. It was g935u firmware for tracfone from T-Mobile if that helps anyone in the future.

I flashed the tracfone rom and everything is working well. I got a software update notification. Should ignore it or is it ok to update?

Bumping the thread...sorry guys. I just jumped ship from Verizon and went to Tmobile today with my S7 Edge along with my wifes S7 Edge. Can I flash her phone with the U firm from TMobile and is the U firmware from tmobile the same U firm that is provided to Verizon? Jist wondering. I've used Odin plenty and understand flash process.

LG H910PR on AT&T LTE?

Hi guys:
i have looked on google etc. but can seem to find a answer. I bought a LG V20 H910PR (from claro unlocked) im using it on AT&T everything is running super fine but can't get 4G LTE only HSPA+. Is that from the phone that does not have all the bands for ATT or is there is something I need to setup?
Thanks,

Did you change your APN?

It has the NXTGENPHONE one I chaged it also to phone but still HSPA+

I will look and see if that model uses the same RSA key. If it does, then you can try flashing the entire AT&T firmware.

Your v20 supports most of att lte bands except band 17, all other should allow you to get lte with att. are you sure the apn is correct, and have you tried forcing the phone into lte mode?, use *#*#4636#*#*, if this menu does not work, download shurcutmaker from the playstore and search for network mode, that should allow you to open the network swtching menu.

Hi,
Were you able to find if the firmware can be installed?

Hi, I also have the same problem. The above mentioned code doesn't work, neither does the software you've mentioned. A bit more help will be appreciated.

Have the same problem on other operator. However if I reset the network settings and don't go into the network options it connects to 4G. If I just open the network settings, without touching anything, it locks to 3G/H+. There's no 4G option in network settings as mentioned. My APN is set up correctly. I did a bit of research and found these threads on Vietnamese forum, google translate was not helpful.

If you can't open the links, paste them in google and use google translate option. Any help would be appreciated.

Is it safe to root/flash ROMs onto H910PR (it has V10j-CLR-PR software) using the H910 methods mentioned here?

Unfortunately I have the same issue, really disappointing. I'll try messaging the seller on aliexpress or I'll try to get in touch with the service on that Vietnamese forum I mentioned earlier. It is obviously software-side error so I am hoping this can be solved.
Also, you can go to service menu by typing *#546368#*910#.
Edit: After a bit of research I came across this thread: https://forum.xda-developers.com/lg-g3/help/lte-option-network-selection-t2827499
It is for LG G3 but the problem is the same. Basically Field test-Modem Settings-RAT selection - GSM/CDMA/LTE is a temporary fix. Other methods require root.
In the Field Test - PDP Setting - APN setting I have "LTE attach profile" which is hidden in the normal Network Settings menu. Don't know will modifying this to match my carrier's APN will change anything.

If you are still ARB 0, then you can use the H910 method. If you are ARB 1 or greater you will have to wait for the firehose method.

Hello, I am new to the site, something similar happens to me, I have an LG V20 H910, with the AT&T system it allowed me to select the 4G mode in the mobile networks option, now I changed the system for the company CLARO Puerto Rico And I don't get the 4G option in the settings, I only get 2G and 3G. It does not let me enter the hidden menu either, it tells me that it does not work on this device, I can not solve with the combination * # 546368 # * 910 #, I select the option only LTE, the coverage goes away and it comes back in 3G. Please, if someone solved this problem can you help me?
