Hi,
TL;DR version below.
Note: This is just a traceback that may help diagnose the problem.
I "own" an Ace (S5830M, everything from i/C works fine). I was playing around with some custom ROMs and evertything was going pretty fine. I installed Jelly Blast (OTA 3) and flashed back to stock a few times, everything was fine and working. Used the recovery/backup functionality from CWM (5.0) to switch between the mentioned installations and it was all good.
Here start the real problem:
During one of the instalation of the custom ROM i went to Advanced -> Format /system (Because probably I miss read the instructions). After this the phone booted and didn't bootlooped, instead it just showed the initial logo (white letters, phone model. Not Samsung animation). As I noted it was stuck I flashed stock from Odin and got it working back.
Everything is fine, the phone works as intended, exept that it "can't" use the baseband I was using before (850 MHz frequency, 3G). I say "can't" because after n tries I was able to send 1 SMS, and only one. All the others failed. And on really unusual occasions I get signal and the phone tells me the provider (Kolbi/ICE) but after a few seconds it loses the connection/signal.
What I've tried so far:
Go to Settings->Wireless Connections->Movile Networks:
There I tried to choose my carrier, but isn't listed 99% the time. The other two are(Claro/movistar). So I set it to automatic.
Check IMEI:
It is the right one
Try to restore from a previous working state with CWM:
I can't it says that there's a MD5 missmatch. (Can I force it?)
Flash a Modem file that is known to work (With another, same model, phone and carrier)
Same sympthoms: does not work.
Dial *#197328640# and play with the settings:
Here I setted to: Type: DUAL_MODE_UMTS_PREF
Band: AUTO
These are the same settings that the working phone.
Flash the stock carrier-branded firmware.
Without luck so far.
====================================================
TL;DR
I have two phones, same model and same carrier. One does not detect the 850MHz band (3G to GMS) so I get no service 99.99% the time, but I was able to send a single SMS. All this after formating /system via CWM.
I've tried to use the same setup and setting from the working phone without success.
Any help or hint would be greatly appreciated.

Yeah, that could fix it. BTW, was there any need to quote the whole OP?
All righ guys I've decided to open this thread so we can work more specific with the phone.
I have a Samsung Galaxy S4 SCG-I545L (from Open Mobile PR) wich i want to use with a GSM carrier. So far this is all I've been trying and the info i can provide (will include Screenshot)
It does not have the option to choose gsm on network.
I've downloaded a stock 4.2 firmware and tried to install it with Odin and with Safestrap but instantly failed, no software damage occurred.
Tried to access hidden menus but no luck with any code.
Somewhere in this forum i'vs read about enabling those options, did the steps but no luck.
Downloaded the ServiceMode Shortcut apk from PlayStore and for my surprise this is what I found (image attached)
Just finished installing the hyperdrive rom but cant switch from CDMA/LTE to GSM/UMTS or Global. When I select the option it automatically go back to CDMA. Manage to insert APN successfully.
Flash it again and still do the same, flash it with the att and still search for cdma, when i set to manual search it said "error while searching for network".
anyone? any soggestion?
hi/hola
i need the stock odin rom for this phone if you have it please post it thanksssss
Hello, I changed my rom several times with Odin, and now I can't get 3G signal, just "G", not even an Edge "E".. I tried a lot of roms after that, roms from sammobile for my mobile operator, any tips to solve that?
Thanks!
#Edit
For some reason, after I installed a deodex room (gt-s5830c_zta_vjlb3-deodex_rb) my 3G started to work again.. but if I just change the PDA, it stop.. Wasn't supposed to PHONE be the file which make the 3G work or not? This VJLB3 is an old version of my operator, when I got the newest version the 3G did not work.. fml

Are you absolutely positive that your 3g was not related to service operator when you were on the stock firmware in question ? Have you tried your SIM card on other phones to confirm the functionality of 3g network ?
Did you check you APN settings :
Dial "*#*#4636#*#*" > Phone Information >Set preferred network type > WCDMA preferred Does it set correctly ?IF not then choose wcdma; press turn off radio then press turn on radio; press home button(not back button). You will get 3g. If not then reboot.
Have you lost your IMEI ? what you see when you dial "*#06#" was it gone on your last non - deodex fw ? what is your phone variation ?
what was your last CSC/PDA/MODEM part , which does support your base band/3g and other things , before you lost it ?
Your country / Region and carrier you are staying too please ,, we might need to flash the only Modem part over Odin to resolve this issue according to instruction i will provide . However you need to be more specific by providing more details such as name of possible custom Roms you did flash. stock CSC/PDA/MODEM details you did try and other minor details will become valuable in this troubleshooting .

Hello, thanks for the answer, the same SIM card worked on with 3g with the deodex rom, and wasn't working before it. I got no 3g with one rom, changed it to deodex and got 3g, changed again and lost, all of this in a few minutes, so wasn't problem with the operator or SIM. I didn't check the APN, I just downloaded an app from my country to try to set it. I don't know if I did lost my IMEI, I have it wrote in the back of phone, but didn't check if is the same after all that changes (and if is possible to change it), I changed the rom a LOT of times, first times with CWM and after with Odin, with the I variation, C and M (trying to go back to original stock). I think the original firmware was an old version of M variation (S5830MUWHKL4 maybe), my country is Brazil and the operator of the SIM card is Claro, the last stock from sammobile I tried was the last one from Claro, tried with and without CSC after splitfus2 it.

I really don't understand how Deodex Rom has anything to do with your 3g/IMEI/APN settings. Because Deodexing is basically repackaging of your APKs in a certain way, such that they are reassembled into classes.dex files.
By doing that, all pieces of an application package are put together back in one place, thus eliminating the worry of a modified APK conflicting with some separate odexed parts.
custom ROMs or APKs are always deodexed to ensure integrity.
Ok so you are from Brazil (Claro) and on C variation of the device, thus splitfus2 and wipe package troubleshooting is not supported for C variation . (Splitfus2 only generates the normal extraction of CSC/MODEM/PDA parts from your single xxx.tar.md5 file, noting more in this case ). Use this pre- configured app for normal parts generation instead with ease .
This is the list of the correct xxx.tar.md5 for your device and you have tried the last update for your carrier from this page ( PDA : S5830CVJMA1/CSC: S5830CZTAMA1 )according to you , right ? and you lost your 3g support ?
I got couple of suggestion for your 3g :
1- Use 2012 tested Brazilian Multi Package Firmware from this page ( PDA: VJLF3/CSC: ZTOLF1/VJLF2) .
2. Check you got the correct Odin and drivers installed on your system ( Odin3.v3.07.Cooperve.exe ; Drivers post ) .
3- Get into Download mode ( pressing Vol(+) + Vol(-) + Power Keys) :
- -press volume up
-Open Odin3.v3.07.Cooperve.exe
-Connect your phone to PC via USB cable.
-Make sure that your phone is detected in "ID:COM" area.
- Put your CSC/MODEM/PDA parts into their respective places . Do not use pit file and Do not tick re-partition though . Factory reset and reboot selected by default >> push the START !
- DO NOT disconnected nor disturb the flashing Nand process , until the process being terminated.
Get into e3 stock recovery and wipe your /data .
Now in your brand new FW :
Dial "*#*#4636#*#*" > Phone Information >Set preferred network type > WCDMA preferred /only and confirmed my instruction in first post has met with your APN settings.
Dial *#06# as instructed in first post ( IMEI box with your 15 diigit number must appear )
CSC is your consumer software customization and it is specified to geographical region and carriers. CSC contains the contains the software packages specific to that region, carrier branding and also APN settings for data connection .
WE can easily change the settings inside our Multi - package we flashed for carrier compatibility etc etc :
Code:
Just type *#272*Device IMEI# at Phone dial pad. For IMEI type *#06#.
Select the CSC that you want.
Click Install.
Phone will be rebooted by itself.
Note –Changing this will factory reset your phone. Do backup before perform this task.
Note – CSC can sometime be corrupt. It may lead to infinite loop. Reason unknown.
report your progress please for future reference ,, Thank you for reading this mate ,,,,,,,,,,,

Me too, I don't know why the heck just the deodex rom got 3g signal, I flashed the same PDA version, but no deodex, and there was no 3g..
Originally my Ace is an M variation, I bought it unlocked on the internet and came a 5830M, probably with S5830MUWHKL4 rom.
Yes, I got that rom from that page and used the splitfus2 on it. I'm waiting my dad get back from work (I'm trying to do the best fix on the phone so he can use it without problems) to start trying again to put the last rom with your instructions. Also, do I really need to flash CSC? This part comes with a lot of trash apps that is impossible to remove by normal ways, and I don't want to root the phone and use 3rd party programs do remove that things.
Thanks!
#Edit
Also, the PDA from deodex rom has 431mb and the PDA of nondeodex has 185mb (same version of rom), is it normal?

Yes you need your CSC as i have explained it in details ,,,and you have too get root privileges for any removal of your system apk's ( If you are under some sort of warranty , you can use UN-root script or galaxy toolbox to reset the counter to zero for avoiding detection i guess,after you have done playing around with phone ,, rooting and using either manual or script method is recommended for bloatware removals on Odex roms , third party apps like disable service and TB is also advised ). Or Deodexed your Rom and remove bloatwares , but you will loose ~70 MB of your precious internal storage ( link2sd or Universal Cronmod could fix the storage problems ) and PDA size you did mention is quite natural .
Still waiting for your final report mate ,,,,,,,
Hi!
So I bought a HTC 10 from Amazon back in May and, even though the product description said it was the US version which had LTE bands for US carriers (specifically 4-AWS), they sent me a M10h, which is the international/asian version that doesn't support band 4. I can't return the phone though, since I'm from Argentina and with the insane customs ruling here, sending the phone to the US and back would cost me almost as much as just buying selling mine (at a highly reduced pricepoint since it doesn't support LTE in my country) and buying a new one.
After a lot of reading here in XDA, paying 25$ to be S-Off, flashing radios, changing roms and kernels, and a bunch of other stuff, I've come to the conclusion that my only alternative left is to change the 06828 NV value (which determinates what LTE bands are activated) with QXDM/DFS tools/whatever program. I've managed to put the phone in diag mode (for those who don't know how, I'll leave a little tutorial in the end of the thread), but when I write the value and then read it again it's back to its original state. I guess this is some kind of protection Qualcomm/HTC/whoever put in place to avoid users messing around with this stuff.
I read in the HTC One M9 forums that users with CDMA phones could change the 06828 value, while I, using a GSM phone, have been able to change 06829. I tried using a Verizon radio, which turns on and off the diag mode for some reason, and a Sprint radio, which gives me a "diag error response" in QXDM when I try to read/write any NV value.
Maybe a custom kernel can help avoid the write protection for NV values? I don't know a lot about that kind of stuff, so it's the only thing that I believe could change my situation
Phone info:
White HTC 10 M10h model
LeeDroid 10 v2.4.1-stable rom with CleanSlate kernel
S-Off and root
Baseband version [email protected]_51.01_F
---------------------------------------------------------------------------
For those who can't make it to Diag Mode:
1) Install the HTC Diag Drivers in your PC
2) Install a terminal emulator in your phone (in my case I used SManager)
3) Connect the phone to the computer with the USB cable
4) In the terminal emulator use:
Code:
su
and then
Code:
setprop sys.usb.config diag
5) Now touch on the "Use USB for" notification.
6) If everything worked, the phone should block you from choosing any option in the list besides Charging and USB tethering
7) Choose USB tethering
8) Your phone should appear in the Windows Device Manager as HTC Diagnostic Interface, which means the phone is in Diag Mode
9) To return to the default USB mode, repeat step 4, but replacing setprop sys.usb.config diag for
Code:
setprop sys.usb.config mtp
--------------------------------------------------------------------------
Does anyone know any way to make my phone work? Any kernel made from scratch I can try? I'm really desperate.
Thank you all for reading!
Up!
Bump... has anyone figured this out? The M8 and M9 guys have reported flashing a Verizon RUU/Firmware to allow the LTE NV values to stick, but this does not seem to work on the HTC 10. I've tried everything and have gone this far, but I just cant seem to write the NV values. I've tried QPST + QXDM, as well as DFS. I am not sure if it's the actual firmware/radio itself (though I've also tried them ALL), or just the actual Kernel.
I am stopped on the same spot. I used ElementalX-HTC10-1.06 as kernel without success. Were you able to get anything?
After reading through the OPO thread and someone confirming they saw bands unlocked for their OP2, but could not test if they are working as well as reading through the OP3 and similar threads with our processor I finally delved into trying this. Here is the quick guide of how to do it. Sorry if there is any confusion I will try my best to make it concise as possible. This is my first time writing a guide up for XDA.
I have not been able to test each band to confirm it's working, but it is showing up in Network Guru. I am on AT&T so I only unlocked AT&T bands (bc that's all I care about currently and it makes it easier for me to test)
I WILL NOT BE HELD RESPONSIBLE IF SOMETHING WRONG HAPPENS TO YOUR DEVICE BY FOLLOWING THIS GUIDE!

[URL="https://forum.xda-developers.com/member.php?u=7846474" @baskaflyfer[/URL] Rmt Storage Patch Zip
Here is the OP3 thread I based this guide off of and credit to all those mentioned in there as getting this far would have been impossible without them: https://forum.xda-developers.com/oneplus-3/how-to/guide-unlock-additional-lte-bands-t3519563
OKAY:
PreReq's:
1. Rooted
2. TWRP or like
3. RMT Storage patch from OP3 forums: SEE POST BELOW!
4. DFS Explorer - Find via searching XDA, again checking OP3 thread or OPO
5. ADB installed (whether that be minimal ADB or like from other toolboxes out there)
6. QPST - Check forums for download
Guide:
1. Put phone in MTP mode if not default (Some default to charge mode) Just go to status bar and press the charging mode to change to file transfer
2. Place file from PRE-REQ #3 in a folder you'll remember
3. Reboot phone (or shut down) and when coming on hold Vol Down+Power for a few seconds and let go
4. Boot into TWRP
5. Backup (If you don't have a backup of EVERYTHING at this point, probably a good idea to do so)
---If you do take only EFS
And install file from #3
6. Restart into System
7. Open up your CMD and run this ADB command :
adb devices
adb shell
su (you will get pop up on your phone to give root authorization for ADB, authorize it)
setprop sys.usb.config diag,adb (this will open your OP3 diagnostic port)
Click to expand...
Click to collapse
This forces it into DIAG mode, check your Device Manager to see if you see a port connection displaying a COM PORT.. IF NOT, you need to install drivers--Search thread for drivers, likely will be find in original OPO or OP3 thread.
***********THIS SECTION IS PURELY PRECAUTIONARY*********************** SKIP TO 11 IF YOU WANT
Purely precautionary we did not have to restore any QCN as they do in OP3 due to encryption:
8. Install QPST, open QPST
Now fire up QPST and go to "Port" tab, and choose "Add New Port" ,
9. On "Serial/USB Port" tab, unchecked the option of "Show Serial & USB...bl bla bla" option, you will see your phone listed there as a "COM#" (# is a number depending on your PC) choose it, and click "OK"
10. Now choose "Start Clients" from the Menu tab above, and choose "Software Download"
**********************************************************************************
11. CLOSE QPST. Open up DFS Explorer, when the signup option comes up it is up to you whether or not you want to register for an account (Good to support them since it's a good application) If not, press the X and the app will be there
12. You should see your PORT listed as you did on QPST. Double click on it (If you can't; confirm QPST is closed otherwise you won't be able to connect to the port) You should see it turn green and highlighted ONLINE if you successfully connected
13. Go to the "Band" option then click on "LTE"
14. Press READ; Give it a second and you should see all currently enabled bands listed; If you want to compare you can go to "Network Guru" and press the 3 dots on the top right and press Band Locking and then press LTE.. Should list the same ones
15. Check the additional bands (Just because it says it's enabled, doesn't mean hardware wise it will work due to chipset hardware limitations; This is why as you all do this if you can confirm which bands for you connected and/or didn't connect we can keep a running list.)
16. Press "Write"
17. Since we're in Demo mode it will count down and then in the LOG box you'll see operation successful
18. Restart the phone at this point and disconnect the cable
19. Wait until it boots up again and go to "Network Guru" press the 3 dots again and go to Band Locking and you should see the new bands listed
*If you don't press the 3 dots and press Clear forcings and it'll prompt that a power cycle may occur; That's okay, let it, mine did, wait until the phone comes back up and repeat 19 and the new bands should be listed.
20. LET US KNOW ON THIS THREAD what bands are working, what aren't. It will allow us to further play with the device to discover if there's limitations or if further editing is required like in the OP3.
*Please press THANK YOU if this guide was helpful.
**Sorry for the missing of some info in the guide! Seems when I added the HYPERLINK it removed most of the other text before it so it started at #4 instead of the remainder of #1-3

usb debugging should be enabled i think, you didn't mentioned that. " (this will open your OP3 diagnostic port)" and here should be op2 i think. thanks for thread, i have a2005 and want to unlock 20 band(800mhz), will try asap, now i have exams running out of time. btw, so the risk of breaking phone is low right, this steps only modify EFS partition only? so hybrid recovery and flashfire can backup/restore if enything goes wrong
What is the benefit from this? Better reception?

So... Are your at&t bands working now? Which bands specifically?

Still something is missing
Hi, I think something is missing. Let me describe what I have done on a A2005:
1- I downloaded the rmt_storage from the link provided on Pre-reqs #3.
2- I backed up EFS, installed the patched rmt_storage, reboot into system.
3- I installed the modified HTC modem driver as unsigned driver, did the adb diag port commands, and the phone is recognized by DFS.
4- On DFS, I must click on SPC 000000 since the log shows errors. I'm not sure if a specific SPC value is required ***
5- When I click on Read, it captures the values, I wanted to add Band 3 (1800) so I checked it and then clicked on write. The logs showed that the write was successful.
6- I restart the phone, connect it and load adb diag port commands again, load DFS, click on read and the values stay
7- When I open Network Guru on locked LTE bands, the list shows me the previous one, as if nothing has been written. I restarted the phone already several times, still no LTE on Band 3.
Besides the SPC code, I might think that:
- The rmt_storage somehow it's not working
- DFS keeps the values but they are not reflected into Network Guru or phone. I already set 4G/3G/2G enabled on the connectivity options. No changes
- Maybe there is another value that needs to be changed with another tool such as QXDM
Any help would be very appreciated!!!

Hi, I think something is missing. Let me describe what I have done on a A2005:
1- I downloaded the rmt_storage from the link provided on Pre-reqs #3.
2- I backed up EFS, installed the patched rmt_storage, reboot into system.
3- I installed the modified HTC modem driver as unsigned driver, did the adb diag port commands, and the phone is recognized by DFS.
4- On DFS, I must click on SPC 000000 since the log shows errors. I'm not sure if a specific SPC value is required ***
5- When I click on Read, it captures the values, I wanted to add Band 3 (1800) so I checked it and then clicked on write. The logs showed that the write was successful.
6- I restart the phone, connect it and load adb diag port commands again, load DFS, click on read and the values stay
7- When I open Network Guru on locked LTE bands, the list shows me the previous one, as if nothing has been written. I restarted the phone already several times, still no LTE on Band 3.

In Network Signal Guru, choose clear forcing. And check the LTE bands again,
or, install Network Signal Guru after you done unlocking, else it will show what it remember on previous set up

the guide forget to mention that u need to flash rmt storage patch before do any modification,
else no mod will be saved (will revert upon boot)
the patch is in my OP3 thread
Thanks! So today's update:
1- I connected the phone again, ran adb commands, reviewed the bands again on DFS tool and settings stayed. I'm pursuing to enable Band 3
2- I uninstalled Network Signal Guru
3- On Recovery, flashed again the patched rmt_storage, boot the phone, wrote the values again on DFS tool. Reboot phone
4- I installed Network Signal Guru and now it's showing up on the bands lists. I unchecked the bands default on A2005 and used the ones from Eruper/Asia Model as FDD-LTE: Bands 1/3/5/7/8/20 and TDD-LTE: Bands 38/40/41. My provider in Costa Rica (Movistar) uses Band 3 (1800) for their LTE. I clicked on Band locking, clicked on GSM and WDCMA and removed all checks. Then clicked on LTE and left all LTE bands in hopes that it will connect to that frequency. The list shows:
B1: 2100
B3: 1800+
B5: 850
B7: 2600
B8: 900 GSM
B20: 800 DD
B38: TDD2600
B40: TDD 2300
B41: TDD 2500
When I only picked LTE bands as checked, it never resovled to get connected to any cell base.
5- I dialed *#*#4636#*#* to access the information about the phone and monitored the signal setting it up to "LTE Only". No signal on that either
Top of my head, I will restore the qcn backup I made and restore the backup I made for EFS and start again. Now it's saving values after reboot, which is great, but not identifying anything.
Is there any log worth posting here? I read on the OP3 guide that they were restoring a qcn file with bands enabled. Is it worth trying the same?
Anyone that has LTE band 3 enabled would be very appreciated if they post their qcn backup

So... Are your at&t bands working now? Which bands specifically?

I have not been able to further test as all the phones I compare to that are also AT&T ie: AT&T S6 are connected to the same Bands as me so cannot test til I get to an area where other bands are available currently. Will report back as I can test, but was hoping others can test in the mean time as well.

You shouldn't need to restore any QCN or EFS, just re-check the bands you unchecked and it should pickup all the bands again. Also, confirm your APN is correct to be used with LTE?
Did you get ANY LTE Bands before this mod? Or you only have LTE on Band3?
You can use RAT locking to enable LTE Only rather than unchecking all the WCDMA and GSM bands. that way it'll force LTE, if it doesn't go to the Cellular Network tab and press the Preferred NETWORK to go to LTE ONLY.
sadly for me nothing happened, i have a2005 and want to add band 3 and band 20, did everything 2-3 times whats in a guide, everything went well, write process was comlete but bands didn't added
When you say didn't add, you don't see them in network guru or you see then, but unable to catch signal on them?

You tried to force clear in network guru? If so, when you reconnect and enter diag mode and go to DFS, press bands and LTE, press read, did the changes you made stick?
Just so ppl around here know... there is old forum about band OPT band unlocking with various trials of changing bands, which failed, due to missing RMT patch OR BUT it got MANY juicy info !!!
in the past other users sent me qcn/qcnx files of the EU and CN models ( credit: whoever sent me these files from the old thread ) - I hope this help you out.
keep up the good work ! :good:

Have you tried what we said here? And tried to see if you can band lock on 3?
I'm going to see the qcn based off of the op3 guide as well as they had to do qcn restoring.

not yet...it will take me some time, i'm a master's student in exam period.
nontheless, as you can see from the old forum, i'm really interested in opening LTE band 3 on my A2005.
Thanks guys! I live in Venezuela and we use band 3 for LTE and I have the EU version. I'll try this guide today
EDIT: I tried without success, I did all the process but i do not have LTE signal on Band 3. On Network Guru, Band 3 appears as supported. I tried RAT locking but It keeps without signal.

Thank you for the qcn files. I've tried it, and it overwrites my imei, which is expected. Then I tried to replace the imei with mine by hex editor, but flashing the modified qcn still overwrites my imei. We may get into the same trouble with op3, which is the imei encryption.
