GT I9305 data speed in U.S.A. T-Mobile is 0.12 Mbps (It crawls).
In Northern Europe recently, using a data only Sim on T-Mobile, it worked at 3.00 Mbps, not really fast, but usable.
Wi Fi speed at home is 15 Mbps.
Everything else runs great.
No amount of tinkering with settings and APNs changes anything.
Changed firmware using Odin from 4.1.2 to 4.3 twice, I9305XXUEMKC and now I9305XXUEML5.
Root or no Root makes no difference.
These firmwares I beleive do not change the modem which does not seem to adjust to U.S. standard.
Can this phone run at 3g or 4g in U.S?
Is there a modem that can load in Odin, which I know how to use, that will give desired result?
If so, what and where is it?
If not Odin loadable, kindly use plain step by step English.
If no U.S. modem exists, will trying other European modems make any difference and/or brick the phone?
Thanks for any help or direction.
The first thing I would highly suggest is, DO NOT TO FLASH A MODEM THAT IS NOT FOR YOUR DEVICE. That is a very good way to end up with an expensive paperweight. Have you tried updating PRL / Profile ? Have you contacted your carrier to have them reset your Data on their end ? There is a thread HERE with Modems for your device. You may also want to ask about data speeds HERE.

Thank you for your help.
T-Mobile, the carrier, did tell me once they would make some kind of adjustment at their end, but no difference.
What exactly is a profile and how is it tuned for this situation?
Will look at the other two threads.
I'm not sure about the GT I9305, but it should be the same. Look in Menu - Settings - More - System Update. You should see Update PRL / Update Profile. I would also say to check out THIS post. Plus the thread HERE has some good general information.
But as I stated before, I would call the carrier first. Have them reset your Data on their end.

Will begin by contacting T-Mobile and asking for Data reset.
Update PRL/PROFILE not found.
You opened a number of other doors. It will take awhile to thoroughly check them one by one.
Will post final outcome here.
Thanks again.
Just a bit more info. A fellow member of the Assist Team has pointed something out to me regarding your issue. It was mentioned, that it is very important on T-Mobile to make sure that your APN is set to " FAST " . Otherwise your data will be slow, or none at all. A quick search came up with THIS THREAD. Also be sure to write down your current APN settings where you can recall them. Or better yet take a couple of screenshots of your current APN's , and save them to the PC / Laptop. Or anywhere other than the device, as a CYA measure. Remember always read, read, read, and re-read all information before proceeding.

Did the following today:
Contacted T- Mobile and requested a Reset from their end AND inquire if a U.S. specific Modem file exists for the I9305.
Downloaded from two of the sites you referred me to, some 20 Modem files.
Using Odin, installed five of them.
They all worked about the same with no real difference or improvement.
Restored the Modem file that came the OS firmware.
Checked the APN site you mentioned and tried all sorts of various combinations including adding a dash to tmobile and using FAST.
Nothing made a difference.
Am now back on APN default setting, the phone will remain on for three days that T-Mobile said it needs to do its configuring.
It seems to me that the modems for this phone are all based on non U.S. standards and even if a U.S. modem exists or can be built and used, it might not make a difference if the issue is hardware based, which is something that cannot be readily changed, if at all.
What is hard to fathom is that the phone indeed, does work in 2G, but so unbelievably slowly, have to suppose, some other factor, that we have not addressed, is causing a bottleneck. Why would Samsung make a phone and T-Mobile
offer a network that they knew would only operate at a 2G speed of 0.12 mbps? That makes no sense.
Will await the Reset outcome, also anticipate an upcoming Android firmware update to 4.4 and will keep looking for an answer.
If all else fails, will then consider another carrier or another phone, but not giving up yet.
Your continued interest is really appreciated!
Robbbbert I would at this point suggest asking on THIS thread. As we do not want to bypass the Purpose of the XDA Assist Forum. One last thing to check is that your Network Mode. Menu - Settings - More networks - Mobile networks - Network mode. Make sure it's set to LTE.

After much reading, and stumbling over the same posts repeatedly, I must ask for help.
Heres the phone:
Gt-i9100
2.3.6
i9100NEKF2
2.6.35.7-i9100XWKK5-CL754841 [email protected] #2
Checkrom RevoHD V4
CriskeloROM Gingerbreak v32
Currently have a Optus sim loaded into it, staying in Melbourne Australia.
Optus seems to be lousy, I've talked to several people who seem to agree. Since public perception is far from accurate, I cant really blame optus entirely. I havent tried any other SIM cards yet since I need the optus number at the moment.
I've tried quite a few ROMS and quite a few different Kernels, not being able to tell much of a difference in signal strength. The phone will have the 3g icon lit up, but refuse to do almost any activity. Then five minutes later in the same location it is working perfectly, with a ping of 147ms and download rate of 327.7kB/s (using Speedtest.net)
Since I am using KitchenPro I am able to change the modem easily, some dont work, others do. How do I narrow down which ones are best for the phone? The answer of "use it for a little while and you'll know" cant be the best answer. Is the carrier-shipped modem the best that is available? I've read the modem ref guide and it doesnt offer anything other than a list of letters and numbers. Some people have reported things working well with telstra on particular modems, but nothing on Optus.
1) Is a baseband or modem something that will either work, or not work? Or there a signal difference from one to the next.
2) I almost always have 3+ bars of connectivity for the cell service, it works fine, all the time, even with the modems that did not allow data connectivity the phone always seems to work. Does a modem package effect both cell service and data?
3) What would be the most effective method of testing a new modem?
4) Is there a guide somewhere that lists the guts behind the modem packages, ie frequency ranges, so that I can look up the carrier, and match it manually with a modem?
Please Help! With spotty services available, and no means of telling if my problems are carrier related or phone software issues, I find this quite frustrating.
Thanks for reading
UPDATE: Boost Flash Guide (Work In Progress)
Because so many people have PM'd me, I decided to post what I currently have, and will edit as people let me know what does or doesn't work. This is actually a collection of screenshots with my settings from QPST and CDMA Workshop, as well as my phone EPST settings. It should be easy enough to follow.
Disclaimer, Thanks, Credits, Etc....
I'm not responsible if you brick your phone, get kicked off your service, get a headache trying to flash your phone, etc.
Most of this work was originally done by the OPs of the following two threads (as far as I know, anyway), and a HUGE thanks to both of them.
http://www.cricketusers.com/verizon...-htc-thunderbolt-cricket-wireless-almost.html
Thanks to Oriax123
http://forum.xda-developers.com/showthread.php?t=1182260
Thanks to Eljean1
Ok...here's what to do:
1. Download the stuff you'll need...
QPST
CDMA Workshop
the Legal Flash Guide in Post 1 of the following thread: http://forum.xda-developers.com/showthread.php?t=1182260
ThunderboltBoostSettings.zip, found here: http://dl.dropbox.com/u/37958254/ThunderboltBoostSettings.zip
2. Unzip the ThunderboltBoostSettings.zip file. Inside there are several folders and the HTC drivers you will need.
3. Enable DIAG on your TB (##3424# - Reboot to Diag+Modem). If you don't already have your 9k modem installed, the HTC drivers should allow you to update drivers. In Device Management, you should see two unknown High Tech Computer devices. The second one is for your 9k modem. Update driver, pick from a list of drivers, select all devices, and use the USB Modem under HTC Corporation. You should now see the modem listed under Modems.
4. Follow the instructions in the CricketUsers thread, Post 6 to get your MEID working on Boost.
5. Next follow the instructions in the "How to: Basic" portion of post 1 in the same thread. These 5 steps are very important! I used PRL 01115, but whatever works best in your area.
6. Your Phone (Which should be recognized in QPST as a SURF/MSM 7630) should now have the correct MEID. Your modem should have ESN 00000000. Don't worry about the rest.
7. Now use the Legal Flash Guide to obtain your donor phone information. Skip the steps about reading memory to find MEID locations. We did this in step 4.
8. Stop once you get to Step 10 in the Legal Flash Guide. Using the folders included in the ThunderboltBoostSettings folder you extracted, use your donor settings and make sure that everything has been transfered over to your TB. In the screenshots, I highlighted things I had to change manually (and of course removed my personal info). Some of them may have changed when the NAMs were written in CDMA workshop. Each folder corresponds to the Program, Radio, and Nam I got them from on my device.
Final note: What finally kicked my 3G on was changing the User Profiles in M.IP in QPST to read 0 on my phone and 1 on my modem. After that I rewrote the HA/AAA passwords on both active profiles, both radios, then rebooted my phone.
I will review more tomorrow and update if necessary.
Ok so here's the bottom line: Got my TB fully flashed to Boost Mobile after weeks of trial and error. I have talk, text, data at 3G speeds (around 1300kbps download and 760kbps upload), MMS, and simultaneous voice and data with any SIM installed. I assume this means that it's also possible to flash the TB to Sprint. I'm not a developer, so I am doing a lot of guessing...but there are no other posts with instructions on how to flash the TB to either Sprint or Boost, at least none that I've found. It'd be awesome for XDA to have it first. If any developers/mods would like to get a tutorial up on this, PM me and I'll share the info I have.

Thats awesome! From what ive heard, a lot of people would be interested in how you got this working.
Great Job
Thanks. Again, mostly a trial and error process on my part. I used guides from the EVO forum here on XDA, as well as info from the Cricket TB forum. I'm putting together as much of what I know as I can without starting over on my TB. The trick is in the M.IP and PPP Config settings in QPST Service Programming. For the last week I've had a connected status, but couldn't get a stable connection. When I changed the Active user to 0 on the CDMA radio and 1 on the modem, the signal stabilized. I'm hoping to have a clear and concise tutorial up this week.

I seem to remember reading that Sprint actively authenticates their phones and de-authorizes ones that aren't on their Sprint system.
The phone must register on the network with an ESN in the Boost database. I've been told they won't even let customers activate Sprint phones anymore.

Such try hards. Man I hate corporate control.
This is why there's such a thing as hackers. They're the digital freedom fighters!
Oorah to you OP you are a beast. Keep fighting the good fight.
Update:
After about a week of using the TB on Boost, the bugs seemed to have worked themselves out. I no longer have dropped calls, and my text messages, while a little slow sometimes, are being sent and received without issue. I did get an error 16 the first time I used Google Voice. I hung up and redialed and the call went through. I swapped ROMs without issue, and have restored a nandroid backup as well. Both times my data connection remained intact. The simultaneous voice/data works with any SIM card installed.
Due to the fact that this was a trial and error process, I'm not 100% sure which steps need to be included in the guide I'm creating. I'm looking for another TB at a reasonable price, or for someone who has flashing experience and the time to test the process with me. Until I know for sure that the guide contains only and exactly what is needed, I won't post it. Please PM me if you have any ideas.
data
I' ve flashed tb to boost as well. how did you get the mms and data to work..thanks
well done sir
Sorry guys, I was experimenting with an EVO 3D and lost my data also. Smh...
Well now at least I have the information to finish the guide.
Are you getting any type of data connection at all? The data signal icon isn't reliable until you get a real connection. Install Sensorly from Market and look at the Details tab.

Is it still working?
So...is this still working after a month or more? Seems like this is ESN flashing like is done on StraightTalk and then after about 6 weeks they cut you off. Any cutoff.

Never heard of that. Everything is still fine. I've been with Boost for years. Switched to Cricket for about 2.2 seconds...encountered the data throttling...right back to Boost.

Sprint is seeking out those flashed illegal phones. As they can tell by other info that is.sent to them.from your phone. Also don't use a flip phone as a donor phone when you have an android.... As your data.maybe like well over a gig or more. They boost like what up and se you are flashed illegally...
Why on boost, no lte and Verizon is not compatible with sprint pre bands....

I am planning on flashing my Thunderbolt to Boost in a week or 2 but was wondering what donor phones are recommended to use for this? I actually wanted to get a Samsung Galaxy S3 with a bad ESN (since is cheaper to get) and flash it to Boost but I haven't found a good guide for this except for THIS which is a huge mess.
I heard that you cant use a Cricket guide to flash a thunderbolt to Boost, it is not the same guides.
I give you props for getting flashed to Boost how ever i would love to see your exact guide on how you did it and not attaching like 3 threads to the some what guide.
I have a guide which i found here in the forum on how to flash the EVO 4G and it was a step by step exactly how to do it, follow that and no problems, was so easy to follow.
I would like to give the Thunderbolt to my son thats why.
?? about flashing to boost
excellent job of getting everything working. I have put an E4GT on MetroPCS but never got MMS working, now I am on to my next one another E4GT to boost. I wanted to ask about your reference to changing your MIP profiles. I believe that I need to modify something there also. I currently have everything working but 95% of the time I only have 1xRTT, but I know that Boost has 3G in my area. Any ideas??? Again great job:good:
thank you for this guide
I was wondering if this guide could work for the incredible LTE?
I'm having two issues and I'm thinking / hoping they both can be addressed at the same time.
1. My S3 locks up alot. It happens when the screen times out on most apps and it tries to go to sleep. Any button will awaken it but no buttons actually function, including power. Pulling the battery is required to reset it. It doesn't happen on the home screen.
2. The phone is rooted (not by me) and I'm using it in Costa Rica on a GSM network. I have phone and text but no data (except wifi). I have APN Manager Pro and have added Kolbi, but when I got to set the APN, there's no options. If I manually add it, it may or may not appear in the list, though it will appear in the APN Pro listings.
Even when it does appear, there's no real data coming thru - a couple of bits slipped thru on various combo of settings, but nothing streaming.
I'm a newb at this, but reading and learning.
I just want something dependable and efficient. What I use - phone, text, email, GPS, and some data. No games or such, just the basics.
I'm not sure what to fix first. I'm thinking a different ROM could fix both issues. Which ROM? I'm confused by the ROM options. I should be able to get 2G/3G without the ATT ROM.
Something else I should be doing?
Info:
Kernel 3.0.68-KT747
4.1.2
JB - build 13
hardware I535.10
Thanks!!

Kurt this is the Verizon threads. The verizon phones are cdma not GSM. So either your posting in the wrong threads or you have the wrong device.

All LTE is actually GSM, so any Verizon phone with LTE has GSM. Hence the LTE SIM card in your phone.
See [GUIDE] Set up Verizon Galaxy S3 as World GSM Phone (confirmed working) - http://forum.xda-developers.com/showthread.php?t=1809314
I can post the GSM question on that forum if needed, but there's still the lock-up issue.

I would definitely post in that forum, I personally have no experience getting gsm to work, but you'd probably get better support asking in that thread or simply following that guide again.
As far as your screen locking issues, are you running any kind of a custom rom or kernel? Phones lock up sometimes when the voltages are lowered or cpu is over clocked. Sometimes when I have random occurrences like that, a simple reflash of a rom will fix strange bugs like that.
If you're still having problems, then I'd odin back to stock, and if that still doesn't work it's probably a hardware issue.

Hello everyone. I was hoping that some of you that are more knowledgeable about this stuff could help me out here. I recently flashed from CM 10.2 to KitKat (4.4.4), which everything went smoothly for the most part. However, I've noticed that my phone constantly has no service. I should probably state that I live in an area with very low service to begin with, but prior to the flash I was able to get at least a bar inside my house. Now, I'm unable to get anything.
The first thing I could think of to check was my settings in the phone. The data is enabled, CDMA Roaming mode is set to automatic, CDMA subscription is set to RUIM / SIM, and the Preferred Network Type was Global. I wasn't familiar with the global setting as I was used to seeing the LTE / CDMA / EvDo options there. So, when I clicked on it, it now gives LTE, 3g, 2g, 1x, and Global as options. I tried changing it to 3g, but the changes would not save that way. The only way I could get them to save was to power off the phone, take the sim card out and put it back in, and then reboot and switch them. Once i pick a new setting (which is now set on 3g), it locks it and I can't change it again without removing sim card.
When I look in About Phone > Status section, I'm seeing the network says searching for service. The mobile network type is unknown. The service state is out of service, and the mobile network state is disconnected.
Is there anything I can do to fix this issue? If so, I would truly appreciate any type of guidance you guys or gals could give me. Thanks!
I didn't read your entire post but myself and several others have reported signal issues after 4.4.4 flashes on all different ROM types. I think 4.4.4 is just picky about what firmware and baseband you're running. I flashed a few different RPM packages too but in the end I got lucky flashing the BLK3 modem and it seemed to fix my issues. I had noticeably poor signal strength most of the time and a couple times I would look down at my phone and I'd have no signal at all.
Maybe a dev or expert can shed some light on the root of the issue. I don't know enough about under the hood stuff to make an expert diagnosis.
Edit: The unanimous fix that everyone appears to agree on is to flash the MF1 AIO (all in one) package and then flash the ML1 modem only. Problem is finding a legit source for the MF1 aio package seems to be up in the air.
Like I said though, I didn't even do this. I was just trying all kinds of combinations of modems/aio's/ and rpm's and I got lucky. 2 days now with a solid signal at all times. LTE speeds are blazing too, 45 down and 10 up.
Check ur imei number. Or flash a backup and see if that fixes ur problem.

Greetings,
I have a the above mentioned phone on the Sprint US network.
A friend of mine on Sprint recently got a letter stating that they will be shutting down their 4G WiMax while they do upgrades and focus on 4G LTE. It is a stupid question, probably, but will this impact my phone's ability to get 4G and/or LTE?
Also, I am running Cyanogen Mod 12.1... I saw before something about builds for ms8960 and then now it seems it is going back to xt879/c. I have been downloading the Cyanogen for xt897, is this the correct one for this phone? Because I also see a download for xt897c, but I do not know the difference... other than CM is at 10 for the C and 12.1 for the xt897.
Every new version I will wipe the phone and do a clean install of CM... I created a custom boot animation and flashed the bootlogo.bin, so I know how to use ADB and a little bit of the shell...
I am also wondering though, about this f2fs file system... I wiped the data and cache and gave every possible partition the f2fs. Then I read something about zcache not working correctly or not using f2fs? I'm a little confused. Can someone clarify this?
Sorry for so many questions but I can't find this info through the searches. Or rather I can't make sense of it either. If there is any other information for me to supply just ask, and I will gladly provide it.
Thanks in advance!
The Q is not capable of WiMax, so you have nothing to worry about.
As for your other questions, they are pretty much all answered in the CM thread.

Thank you sir! That is reassuring that I don't have to get a new phone come November. And that also means their 4G LTE coverage will be improved so I should have faster network speeds eh? And clearer calls? Will this phone be able to make "HD" calls using the LTE?
Sorry for the follow up but maybe I'm just dense as I didn't really ascertain the answers... could you point me to the right thread? I know there's the 12.1 and then the [Q&A]... would this be a better place to ask?
I'm also curious about the Mobile Networks settings. Is there a primer somewhere on this? I want to know what I should select as the preferred network type... I'm in the San Diego market and I want to make use of LTE when it's available but I only ever seem to get 3G... also I have data roaming and all that included so is it possible the you can have the phone elect to use another carrier's LTE if available over Sprint's 3G? Does it matter which option I select in the preferred networks list - i.e. if I pick something with GSM and the phone doesn't do GSM will it ignore my preference and choose what works? I also don't know the difference between the CDMA Subscription RUIM/SIM vs. NV. I have seen the question asked but didn't find the answer.
Thanks again, any help is appreciated, even if it's just a link or something general. I just want to do the best to get the best network experience with this phone.
Thanks!

I would ensure everything works network-wise on stock before flashing CM. If it doesn't work on stock, get the provisioning etc sorted before going to CM.

Thank you and that's good advice my friend, but the horse is waaaaayyy outta the barn on that one. I've been using CM now since 10. Now on to 12 which is going ok. Has its issues but most of the time (when at home or near a reliable LTE signal) things work alright!
