Optimus 3D SU-760 Users (Pls. Contribute Here) Upgrading, Rooting, etc

Hi!
(Mods, please correct me if this thread must not be placed here.)
My motive is to gain people to help us with this Korean Device. I'm located in the Philippines (I'm a Filipino) and bought the unit with a Korean Friend. I spent hours of searching the net hoping to avail help from developers. I found only few. Most of them in Korean/Chinese language translated using Google translator.
Its been several months now since i bought this, I'm still enjoying my phone despite of it being different (atleast for me who lives in the Philippines and in XDA-Community), compared to P920 who are in this forum. I struggled from upgrading it from Froyo (2.2) to Gingerbread (2.3.5 v20e), believe me, my fingers are crossed when i have the guts to update it, for i couldn't manage to fix it in case it bricked. I Really envy guys who uses P920, they have all the resources from great people here in this forum.
If you are a User of this phone or atleast know something how to upgrade or develop it for the benefit of us noob people (atleast me). Please help a user like me by posting your contribution here.
My contributions: (Problems and the help i found)
If you have a better solutions, please contribute. These are based on my noob experience, please don't laugh at me..
1. Upgrading
There was a thread here who used P920 flash for their SU760, it bricked their phone. I dont know if it was unbricked, how he did that? thats why we need a thread like this. In english.. he he..
As for me, I used the official LG Software Update Agent. It worked like a charm. As a precaution, i backed up all my data, but to my surprise after the upgrade, All programs remained intact! That was from Froyo 2.2 to Gingerbread 2.3.5 v20C...
I have to admit, for me, the 2.2 runs faster and had few problems as a comparison to the 2.3.5. Last week, a Root worked for the v20C, so i Rooted mine. Too exited noob as i was, i accidentally uninstalled minor system app. This drive me to update again using LG Software Update Agent again. And it did! now my software version is 2.3.5 v20e, official software.
If anyone who has a better experience than this or who has an upgraded software than i have, please help me.
2. Rooting
As i mentioned, A week ago, from korean/chinese site (i almost learned their language! lol!) they said in the past they were not successful in rooting v20c or v20e. The Rooting software was capable of rooting v20C and v20E (among others)
The Post for SU-760 came from here.
http://bbs.gfan.com/android-3717040-1-1.html
but then soon, i read from xda developers that it came from this Author
http://vulnfactory.org/blog/2012/02/26/rooting-the-lg-thrill-optimus-3d/
3. 80 Character SMS
This is what drives me crazy about this phone. In my usage, it only sends 80 Characters not the standard 160. I must limit my SMS to 80 characters or else, the message will be broken. I used Go SMS in this setting. I learned that Korean system uses 2 bits compared to our single bit, that's why it only sends 80.
Handset SMS miraculously solved this problem. (i wish it will be the same with GoSMS)
4. Stock Aps
These are killing the RAM usage! This what motivated me to root my device in the first place, and what drove me to accidentally remove system apps. I used the System App Remover to remove them. Maybe Ill use other app next time.
TV w/ Antenna
It never worked here, I also tried it in Manila (the major city in the Philippines), did'nt worked. I wonder if anyone managed to make this work!
Someone Please Help Me:
How to put/upgrade to a custom rom. (So i will be freed from stock apps)
How to Upgrade or Change Baseband. I really dont know much about this but i have a feeling i need to match it for Philippine usage. I wish to have an H instead of 3g connection. a Getril app didnt worked as of the time i posted this. I emailed the author, if i get help, ill post it here.
So far, these are the major issues I encountered, ill just add later if i have more time and recalled some more problem i fixed.
My helps came from Korean and Chinese forum, the translation is very very hard to understand! If there are Korean / Chinese people in this forum who could help us, please do so, atleast in English Language please.

hey dude! you can root official V20E ,right now no rom better than official V20E for poor LG SU760.

@tiger

Thanks alot for posting, atleast im not alone (using SU760) in the universe of XDA-Developers.

Im a hard user of the unit, mine dont restart, (by saying hard, i mean, using GPS, 3G and bluetooth at the same time. my unit gets really hot, i got used to it.. but never restart)

Good to know
Hi All you Guys,
Heres my experience..
Jump Start
As you see I'm also from Philippines too and just had this Device as gift for my Wife almost a month ago (its around my budget that time and its 3D). I got it first using GB and I just updated it using V30B.kdz that I found floating around the web - Here (if you happen to cant download it you can use any proxy known to man to by pass limitations) using LG Flashtool (pretty much automagically and easy) - Here. Back then my Wife is as happy as child. But all has its limit. After update my Wife noticed performance issues, lagging and too much wait times. So I decided to root it using - This but be sure to use v1.6 and to open it use 7zip app for Windows (Google it). After Rooting first off to do was to Install Busybox and try out V6supercharger, w/c eventually made progress and made the phone quite snappy. No problems, redraws and slowdowns encountered from my Wife except that I cant stop to look at the Custom Roms available for SU760 and personally I still think its still too slow from a device having good Dualcore CPU and decent GPU.
Customization
Reviewed a while, talked to some people and downloaded necessary tools and apps. Target was to flash XBSAv5.2 - Here (yes this works on our SU760). First I got many Bricks and Bootloops but able to resurrect my device using this guide - Here and then found out that it would be safe and easier having the x-loader and u-boot made by wkpark, download this (the loaders were inside /files and /resigned, but if you have trouble locating those you could try this pack - Here) and follow this Guide and use this recovery Pesach85 gave me - Here. After all those stuffs I finally able to boot at recovery anytime during bootup, simply press Vol Down while on the Silver LG Logo boot screen and it will launch TWRP, from there you could flash XBSA v5.2 and if you want to try PH85 Kernel on SU760 download this version Pesach85 gave me - Here. Final touch was to apply the build.prop patch located at XBSA ROM's OP and to use the Original V30B Camera - Here. Thats all I did on my O3D SU760 and now somehow it became fast enough having Camera load for just 5 seconds.
Note: My Wife's setup is
Launcher: Go Launcher
Locker: Go Locker
Sms: Go SMS
Social Apps: Facebook, FB Messenger, Tweeter, YouTube
Settings: 3G when needed, WiFi at Home, All Social Apps Notifier ON, All Sync are ON
She get those setup and ask me why her phone slows down.. Tsk women..

Internal SD Card memory is still working after flashing XBSA v5.2 rom?
My experience was not good with that rom so I never tried again even after 30B official upgrade.

Network problems after updating to Marshmallow.

Sprint GS6 Edge - Unlocked by Sprint - Android 6.0.1
I updated to Marshmallow earlier today and everything is great except for the fact that I am not getting signal on my phone. It keeps saying Searching for Service on the top left of the screen and the signal bars stay at 0.
I tried changing Network Mode but I get an "Emergency Calls only" if i switch to GSM/ UMTS and if I try to look for my network provider manually I get no results. With both LTE/ CDMA and CDMA it just keeps looking for Service.
I am not in the States but have been using this phone for the past year or so with no problems until I updated this morning (downloaded .tar file and flashed it with Odin).
I was rooted and had a custom rom before I updated but I made sure to clean the phone and do all the steps correctly to update. Also, the phone gets signal even without rooting/ custom rom in 5.0.2 (again, Sprint unlocked the phone when I first got it).
Any ideas on what to do/ how to fix this? If it is a problem with the update, is there a way for me to go back to 5.0.2?
Thanks for the help!

Same problem OTA update.
Did u find any solution to your problem I am also outside US, I got an OTA update of Marshmallow for GS6(unlocked by sprint), and it can't find the network anymore, I've been using the phone with the same regional carrier for months and now after the update can't find the network.

Same issue here... I have tried everything... and nada!
Also out of the country with a rooted and unlocked Sprint Samsung Galaxy S6 Edge SM-925P - I tried and searched everywhere, even went to a "GSM Phone Genius Store" and they could not do anything for me. I do get on my network (Orange), on automatic or LTE data works fine but I can't either receive nor make calls. At first I thought it had something to do with the Hands Free Activation pop up but after I could not find any solution I went back to 5.1.1 the Hands Free Activation popped again and of course would not register just like on 6.0.1 but... I had all my network connections working fine. I was able to make calls, receive them and LTE data as well. So that was not the issue. I then (rooted) took off the Hands Free Activation pop up by renaming the SprintDM.apk file to .bak just in case you guys want to remove the annoying notification... In all the searching I found that this was a glitch on Sprint's version of the Marshmallow update, since this is the only 6.0.1 for my SM-925P I could not use another country's 6.0.1 I tried jejeje, believe me I tried... So, it appears that we will have to wait until Sprint finds it in them to fix this but I am very hopeful the REAL Geniuses of XDA could come up with a patch for this issue. The guys at the store I went said that the cell's operating system was not getting the GSM network and that is why I could not make or receive any calls and the LTE was working fine. Hope this helps some and even more hopeful that any of the boyz/girlz of XDA take pitty on us and come up with a fix for this thanks in advance...
Mario Bello Samsung Galaxy S6 Edge SM-925P

Is it because you're out of the States has something to do with it?
A few of us did the same thing but didn't encounter any of the issues you're mentioning?!
So far everything is working smoothly. I just can't wait for a nice MM based ROM to come out for Sprint variants..

I guess but I went back to 5.1.1 and everything works fine... So, I do think so... Oh well, me too waiting on a MM Rom to see if something changes... But meanwhile still NOT able to make or receive calls ...

Possible Fix
I had this problem with a Sprint S6 Flat too, what I did to fix it was to download an older firmware where the S6 was gettin signal then extract the modem.bin from it and flashed it in odin, restart the phone and got signal

How did you extract de file to get the modem?
How did you extract to get the modem?

Extracted and flashed... still issues...

Wow really thought this was gonna work, many thanks... I did as you said and was very hopeful... once I flashed the modem the phone did come up with a signal and I could make calls but now the phone does not switch from GSM to LTE back and forth. If I have it on (Automatic) LTE/Data works fine, as soon as I try to make a call it goes to 3g then just signal up but it does not make the call and then it wont bring back LTE, stays on 3g... I'm dying here with this! If I put it on GSM / UMTS I am able to make calls but no Data...
I did do it with the 6.0.1 as it was, I gonna try this, do a factory reset, flash a clean version of the 6.0.1 and then flash the modem to see what happens.
Again, many thanks GTOFerrari, by far the best option TO FIX this I have see to date.

Yeah, I was curious as to how to do that as well, spent sometime in google but I found the way, and it is actually very simple. You download the firmware from which you would like to extract the modem. Then with WinRAP or any software like that you find the firmware and click extract on a folder cause about 5 files extract from it or so and you will see the modem.bin file there. Now, the issue was how to flash the bin file through Odin, it does not say "Phone" anymore like previous versions of Odin, so more google time spent and what I ended up doing was converting the .bin file to TAR and then flashed it through Odin clicking on AP like always. I found a software called PeaZip that converts the .bin file into TAR... There's probably a way to flash it through Odin as a .bin file clicking on one of the other options BL, CP (probably this one CP) or CSC but I don't know which represents "Phone" for sure so I converted the file as instructed on another XDA thread and that's how I did it.
Hope this helps, and again, the props on the solution goes to GTOFerrari...!

In many forums that I've read, mentions that most sprint mobile works only on 3G outside the US
I'm from México and that's how we use it, sometimes get LTE, sometimes not
And the modem.bin is flashed in CP in the latest Odin

conversion of bin to tar?
can you please help with how to do the conversion of the bin file to a tar file using peazip?

No need to convert .bin to .tar
Just flash modem.bin in latest Odin in CP

Tried what GTOFerrari said and it is working now.

Like GTOFerrari said, just click on CP in Odin and put the modem.bin file there... Works fine like that. No need to convert to tar like I did before...
Mario Bello

Same issues
I have the same problem here. Where's the modem.bin located on

I have the new marshmallow in my note 4 sm-n910p used to have Lte network before fine but know I don't have signal. I did flashed the modem. Bin from the version 5.1.1 that used to work but still have the same issue. Any ideas?

Maybe simple but...

You know, I did that and did not work but I took the SIM out and rebooted and it has worked ever since... you probably have already done this but still no harm in mention it, give it a try if you haven't yet, hope it works.
Best, Mario Bello :good:

Thank you for the reply. I tried that without success.. Still no signal. The modem version that I have now is N910PVPU4COG5. Which one are you using Mario, if it is not too much to ask?

Modem version...

I am on a Sprint Galaxy Edge SM-925P though, I see you are on a Note 4 - probably shouldn't matter but still worth mentioning... My modem version is on the 5.1.1 that worked fine: G925PSPT3BOL1
Hopefully one these great guys can help you better, there are real geniuses here :good:
Best, Mario Bello

Thank you Mario. I noticed that my network options used to included in the version 5.1.1 CDMA/EvDo/GSM/ O WCDMA , and my used to work fine in H+ in network mode gsm/wcdma. Now I only get the network options Cdma/Lte .. Gsm/Umts. I will keep trying and let you know if I get it to work.

Need help downgrading

So i used odin to install a rom from my phone i found last night, but this marshmallow rom doesn't connect to my mobile network. I tried installing a older rom from odin, but of course it won't let me. what do i need to do to fix this?

since you have been doing this for 2 years, anything interesting i should try? i just upgraded from 4.4.2, to 6.0.1, installed twrp and superuser, any neat stuff i should try?

what baseband are you on?

and why are you using odin to flash roms? thats not highly recommended when youre not in need of changing your firmware. what tar.md5 file did you flash? if its not connecting to your network, it could have been a tar.md5 for a different S5. here is the link for the 6.0.1 PCA tarball and here is the link for the OK4 tarball. Im currently using the OK4 one and its pretty solid, but if you want the ability to flash ROMs, then you want to stay away from the PCA baseband

sorry, too noob to know what baseband i was in. all i know its a sprint phone, g900p and my original was 4.4.2. i've been trying to flash roms from http://rwilco12.com/downloads.php?dir=Files/Devices/Samsung Galaxy S5 (Sprint) (SM-G900P)/Stock ROMs
but they all have the same problem, it stops at like 1% probably cause i'm trying to revert to a old version, must of flash 20 roms i found on the internet... i'm looking for a kitkat version that would work. I would think thats my biggest problem, just haven't found a stock rom that works. Would i need to clear anything with twrp first?

thanks for the help, this lolipop rom works great

yes, and it might need for you to fix permissions too. do a factory reset (i always recommend doing it 3 times), delete the android folder in both internal and external storage, and then try to flash the ROM again. Id also upgrade to at least OK4 via Odin. After doing that, youll have to reflash TWRP. That should clear up any issues youre having
OK4 tar.md5

no problem. let us know if you run into any other issues. ive had my S5 since launch week (over 2 years) and its been rootd, flashed, rommed, sim unlocked etc etc so many times, its pretty nuts
also, even if your ROM is working well, it would still be wise to get on OK4. Its just a better baseband

could you help me with installing twrp? i downloaded this https://dl.twrp.me/klte/ from the website, its should be simple to install like flashing the roms, but i did it a few times, but when i boot into recovery mode, its still using the android version. like nothing has changed.

it has to be a tar.md5 file and flash it in Odin using the AP slot. Put your phone into download mode (pull the battery, put it back and press and hold, volume down and home, while still pressing those two press the power button until the phone vibrates and then release the power butt while still holding the other 2), itll ask you if you want to continue, select yes. If you need more info about how to use Odin, let me know

G900PXXU1BOD3 rom, where can i find it?

Hi to everyone,
I have this unusual rom in my phone, as I have read through the internet, the XXU1 stands for a HongKong region.
The problem is, that there's nothing about such ROM on the internet, as if it never existed...
The phone was bought as new through online shop..
It has been unlocked through idoneapps. I use it in Europe. GSM and MOBILE data worked fine until I forced to update it through ODIN to G900PVPS3CPK1.
I was able to get the GSM to work, but the WCDMA network isn't available.. and the messages are split into pieces when I send them. As I've read, that is how they're sent in US.
I had tried many if not all of the roms, modems, kernels etc.. available in this SPRINT galaxy s5 thread..
but none gave me back the mobile network 4G.
So I was wondering if anyone has heard anything about such ROM (my original one) or where I could look for it? Maybe you have an idea what to do?

I searched for you. Here is the result.
https://samsung-firmware.org/download/Galaxy S5 (Snapdragon)/5998/ITV/G900FXXU1BOD3/G900FITV1BOD2/
This page explains it all.
I think you remembered a character wrong, it is an F, not a P. if it is really a P, and you are sure your device model is SM-G900P, then you must buy a new phone with a wrong ROM. I don't think that happens a lot. G900P never has a G900PXXU1BOD3 ROM. I think you flashed a WRONG ROM in the first place. DO NOT flash the ROM in this post until you confirm that your phone's Model Number(you can check this yourself in Settings, About device) is SM-G900F.

Thanks for your response. The sad thing is that the phone is G900P. I have attached the screenshot below. I have made a full TWRP recovery of the rom before doing any flashing. I am able to restore it all except the modem, as TWRP doesn't restore modems.
If I put a newer ROM bootloader and modem and restore the backup - I get a bootloop. If i put an older one I get no signal and the lower buttons arent working. Though I found BOG1 modem to work with my current firmware, but it's not fluent. The phone feels laggy and GPS isn't working...
So I am looking for a complete rom that could work in this phone without any recovery..

Can you find ok4?? Runs awesome for me, use Odin to flash it, you'll lose twrp but then Odin twrp

Sorry for the late reply, you didn't quote me, so I did not get the notification that you have replied.
It's very weird that your bought G900P with a G900F ROM. G900P doesn't support WCDMA network, I don't know if it's blocked by software. But the link in my last post indicates that your reseller flashed G900PXXU1BOD3 for you in order to make WCDMA work. I don't know if you can simply flash official G900PXXU1BOD3, because the system with your phone may be modified in the first place. If you simply want to restore original backup with modem, drop back to TWRP 3.0.2-1 or 3.0.2-0, 3.0.2-1 wouldn't mount external SD card so you have to move your backup to internal storage, I didn't test 3.0.2-0 but I assume it's the least buggy recovery for G900P so far.

My mistake,
I believe I had tried to restore backup with those versions of TWRP. They don't restore the modem part and give me an eror (can't remember exactly how it sounds), but as far as I have read, TWRP does not restore modem. It is impossible. So I can only flash it by ODIN, but there is no such G900PXXU1BOD3 modem on the internet..
I wonder, what if I would simply flash the G900FXXU1BOD3 or never rom with F symbol, could it work out for me? Maybe you have read about someone doing that? So far its my only hope...

I don't know if someone deliberately flash a stock G900F ROM to G900P, it would have most likely bricked the device. But I have noticed a slight difference between the 2 pictures you posted, first 1 says baseband version is G900PXXU1BOD3, idoneapps says it's G900PVPU3BOG1, I don't know which one is more accurate. I couldn't find a seperated modem file of G900FXXU1BOD3, yet there is a way to extract it yourself, simply change filename extension md5 to tar and open it with compression software. After flash modem, restore your backup.
Edit 1: Maybe you need to flash CSC also when you flash modem. But no rush, just try modem only first.

Help me!
Hello,
Curiously I have the same problem, I bought the mobile by Ebay to a Hong Kong user and it comes rooted and with problems I do not know how to solve, from the beginning the camera did not focus until suddenly by magic, it focused.
Now I want to do a ROM restoration but I am not able to find that version since from what I see in the answers you have offered here seems to be "trick", have you found any solution? I would appreciate it if you told me so please.
Thank you.
A greeting.

Strange Baseband; Strange problems

Hello everyone, this is my first post, after having read a lot in this forum already.
tl;dr: I flashed several ROMs onto the phone and always had the same problem: Connection to network goes away completely when mobile data is turned on. My baseband is S7652XXMA1 for which I cannot find a stock rom. Don't know what to do now.
Comprehensive description:
So I got a Samsung Galaxy S Duos (GT-S7652) and thought I flash some fancy ROM on it to gather some experience before I go and try with my main phone. So I installed TWRP, which went fine, then I flashed PMP Light ROM, because I read that would improve the performance and I liked the ROM.
The problem is, that as soon as I turn on the mobile data, the phone loses network. I double checked APN settings and tried the same SIM card with my other phone and those settings and everything works fine.
I tried to flash back Stock ROMs, but the problem stays the same.
Now I see two potential sources:
1. Baseband of my phone is S7652XXMA1 and I cannot find the right stock rom for this (although I tried some other Stock ROMs, because I thought they would change the baseband, which they did not)
2. When flashing process reaches the fat.bin (which I read contains the baseband) it gives me an error:
Code:
99%
100%
ERROR: Failed to confirm end of file transfer sequence!
ERROR: FAT upload failed!
Does anyone know how to proceed? Does anyone know where to get a Stock ROM for this Baseband S7562XXMA1? All help is much appreciated

Ok, telephony also doesn't work, if one tries it loses network just as in the mobile data case.
Has no one any ideas, how I could overwrite the Baseband?

Try cm11 with Hungarian baseband.
Is network working on phone properly?
You can also try to flash indian baseband, but keep a backup of old baseband

Wifi works without problems, for mobile network see my posts above.
I have not kept a backup, as I thought just reinstalling stock rom would bring me back to original.
Why do you recommend to flash Hungarian Baseband cm11, so far no baseband rom could overwrite my fat.bin, what does this do differently?

So far I was mostly trying various Stock ROMs and PMP Light Rom. Ok, I will try the Hungarian Baseband cm, if that promises better results. I will report back if that worked.

CM11 gives good performance than stock rom for sure.

Hey, I managed to override the baseband with the Hungarian one through the zip from here: [CM11][GT-S7562] Samsung Galaxy S Duos Kitkat 4.4.4
The problems are still the same. I tried to install the cm11 from the same thread (through TWRP), but I get an error (Updater process ended with ERROR: 7) telling me that I am trying to install on top of incompatible data. I tried doing a factory reset, but to no avail.
Right now I am on |DisContinued| COSMIC ROM | Version 2.5 |KitKat-Mod|Galaxy S Dous|Smooth|Fast|Stylish, which also is based on cm11.
I will try to flash some other ROM from PC, but I don't have much hope that will solve anything. Does anyone know where I could obtain a Stock ROM, that is compatible with Hungarian Baseband? There is a link in the Kitkat Thread above (http://d-h.st/do72), but it only gives me some exe-file instead of the tar.gz that I look for...

I don't think cosmic is based on cm11 its just kitkat themed stock.
Try to again download cm11, u will find a new experimental build on last pages.
U can find the stock firmware from this thread.

Its hosted at http://d-h.st... The only thing I can manage to get from there is a 7z1602.exe, which seems like a bad idea to execute. Can you download from there? If yes, maybe you could then upload it to a different file hoster, I would be very grateful.

Yes i tried to download stock Hungarian firmware from cm11 thread, it isn't working.
i reported it their.
Have you tried to download from here, download your country firmware - https://www.sammobile.com/firmwares/database/GT-S7562/
You will have to flash with odin , their are many good guides available for that on Google

I know that site, but they don't have the version for Hungarian Baseband. I tried some other stock roms from there though, but no success.

They provide flash file which can be used with odin through computer. It will install stock samsung firmware of your country, so it will make the whole phone new, don't forget to backup your data.

I started this Thread because that messed up my mobile network connection, so it is not "new". I need some firmware, that will work with my (now) Hungarian Baseband.

You say that you cant flash basebands through recovery, so now the best option is odin only, now i am out of ideas about for your problem

I was able to flash the hungarian baseband only, no other worked. Now I do need some ROM that works with that Baseband. I posted a request for a new link in the Thread, maybe I then can proceed and make some progress.

Just if anyone is still following this, I have managed to restore the network connection by using the Hungarian Stock ROM, which I finally managed to locate. If anyone needs it too, here is a link:
