Android 3G going slowly? - Android Q&A, Help & Troubleshooting

So i tried some different modems on my i9000. and i decided to go back to JPY (original) before I couldnt flash them in cwm for some error. so i flashed all the modem.bins directly through odin and everything went well, After a day i decided i didnt like the battery life so i went back to the JPY modem. But now the internet is so so so slow it just times out. I have even restored the apn setting and everything, (GSM/HSPDA is on) Data mode activated. It just hardly works. Am I going to have to reflash my custom rom? Simplicity Rom 2.2.1 or 2.1.1 or whatever. ?

So you have the captivate? If so yes you should reflash the rom.

[Q] No data signal??

I was running Eugene's R13 with stock kernel and JK6 modem and all was working fine for the past couple days. Tonight I turned on my wifi at home to download a program off gameloft and when i turned off WiFi to switch back to data, the data signal never came back. I checked the settings and data was enabled. I tried everything to get it back and nothing works. I restored my nandroid back to Samsung out of the box stock and did a factory reset and no data still. I then installed a bionix rom that worked well in the past, nothing. I installed the new Onyx 4.2 and flashed the new JK6 modem and that didnt work. I reflashed Euegene's R13 and that still no go.
Any ideas??
You sound like you are having the same issue as me, I was runing macnut r12, worked great. I upgraded to r13 and it was runing well until I rebooted the phone, then I had no cell network connectivity. I odined stock JFD and phone worked, I reflashed r12 and no dice, I went back to jfd it worked again. I flasged a cw jk6 and an odin jk6 and several modem fles and no dice. I am currently stuck at jfd. If you go in to about phone does it have unknown baseband? I have that now unless I am runing stock jfd
In the same boat here. Please help!
It's actually worse for me. I can't even make phone calls.
Use Odin to go back to JFD, you will be able to make calls / data. Unfortunatley I am stuck at JFD at the moment because no mater what I flash other than JFD, I have the unknown baseband issue. I tried Odin JK2 and JK6 also clockwork Macnut 12,13,JK6 roms, JK2 roms. I also tried using Odin to flash JK2,JK6,JFD baseband and no luck

Hope I'm not being paranoid...

So I noticed that my 3G wasn't connecting all day on my fascinate. I was running Evil Fascinate 3.3.2 with the nemesis ED01 kernel and the ED01 modem. So I flashed the EC01 modem. No 3G. So I completely wipe everything after a nandroid backup and installed stock DL09. Bam, 3G is back. I allow it to update itself to Froyo OTA. 3G working great. I wipe the phone and install the new Community Rom from scratch. 3G is gone again. I wipe the phone and I flash EF 3.4. 3G still gone.
So I'm back on stock Froyo. I'll do more testing later to see if rooting makes 3G go away again, but at this time I'm suitably freaked out.

Looks like smilepak had the same issue. see here also
Just a suggestion for when I get random bugs that others don't seem to get. I re-download the file i tried to flash, from a different link if i can get it. A lot of times it's a bad download
I think the piece of code in the unknown tethering module is phone home code. I think it's a combination of the phone home not happening, and high 3g usage triggering a disconnect on the other end. I can't prove it yet, but I'm trying to figure out a way to get tcpdumps for wireshark. I know my usage is very high right now.
This seems to be a problem alright..see this thresd: http://forum.xda-developers.com/showthread.php?t=1051543
Mine is low. For me, going to ed01 started the whole mess. Eve going back to dl09, didn't solve anything. The 3#g shows up and random disconnect every five minutes. Remind me of old modem days of bad handshake and reconnect loop. That is basically what it is doing. Once connected, hell of slow tried speed test and the result was horrible.
Looked through all settings values, factory reset, tried several different radio and from. All no such luck.

[Q] Loss of signal( LOS ):confused:

here's my problem:
when ever i leave phone to be in deepsleep mode,
i cam back to find it looking for GSM signal with no hope,restarting fixing the signal.
tried diffrent roms, CM7, MIUI,with all kind of kernels nothing works
phone condition is fine,did't drop it or hardware issues on it.
was working great for last 6 months, but after i flashed a ton of diffrent CM roms this starts to happen,
my thoughts:
could it be a NVdat.bin issue doing this?
if so, what i can do to let the phone re build fresh ones,
+ i have old backup of EFS folder.
can you share your thoughts please?
I had the same thing happened to me and my friend's phone in the last week. Both running the ported gingerbread roms. Had to Odin back and finally working. Not sure if it was the Rom or something. My phone says it shows a baseband of UVKB5 which is the correct modem.
Finally flashed back to froyo and had it working, now just reflashed a gingerbread rom and it's working again.

odining back to JFD solved the problem.

[Q] No CDMA Service on Custom Roms

Hey guys, I'm not new to rooting or flashing ROM's but I've encountered some issues. Basically, I was on an early JB Rom and everything was working fine but it mostly was in roaming and would go from 2-4 signal bars.
I backed up and have attempted to flash:
PACman
MIUI 2.11.23
As well as CM10 by joker and AOKP CM 10.
Every flash I end up with no signal bars and no roaming, also following all install instructions in the threads.
I have tried flashing with and without prop tweak, i have even restored the backup all with the same results:
Empty signal bars, occasional R for roaming, every call says mobile network unavailable.
I have also fixed permissions, and have tried to flash via TH3Bill CWM and TWRP recovery... what am I doing wrong? The backup isin't even working!
I wouldn't know off hand, but here's something you can try while waiting for a more professional member to come to the rescue.
System Settings> More>Mobile Networks>System select>Home only
What's your current PRL, APNs?
if it was me I'd sbf back to stock and see if I had signal then go back and try a custom rom again

Before sbf'ing if you have a back up of your stock ROM or any ROM that has the update profile/prl setting in it, restore that back up and try updating your profile/prl then wipe/flash your new ROM.
I usually have this problem when I switch back to my Photon from my ET4G, but updating the profile usually does the trick.
When I restored my old backup, I had the same problem. The only fix I could find was on MIUI and selecting automatic netowrk before flashing options chooser. Any other rom would make no changes on automatic or home only. I am going to try a fresh install and if no luck will sbf today. I'll keep you guys posted.
Thanks!
**EDIT** Does it matter if I use Th3Bill's CWM recovery or TWRP? I have tried both with similar results. I jut noticed CWM is usually posted with the ROM builds... does it makes a difference? If so, what should I use?
Normally both work just fine, as long as you're using one of those two
I spent too much time flashing roms and wondering why they wouldn't work right, when I was using the stock CWM
I think It's just my opinion but I have preference for bill's cwm
Having this exact same problem. Did anyone figure it out?
No Radio/Signal
I recently flashed the latest MIUI.US V5 3.4.5 for the Photon provided by Th3Bill. I am familiar with the process of applying ROMs. I tried to go back to Beanstalk, JB, and ICS and could not recover the radio signal. I even restored a few backups with the same result, no signal. I flashed the MIUI V5 3.4.5 ROM back to the Photon and it worked flawlessly. Can anyone please help? I would really like to get off the MIUI ROM, it does not appeal to me like the standard versions of Jelly Bean that Th3Bill has produced.

Flashed Omega rom and now WIFI range is extremely poor

Hi all,
Pebble Blue i9300 SGS3 unlocked
Was on Android Revolution HD 14, full wipe flashed Omega 33.2 which is when I notice the issue where I would only be able to connect to WIFI within 3m distance from router (used to work from outside house and across the road now only in the same room). I can see my network at full strength in other rooms of the house but I receive authentication error/incorrect password despite it being correct.
I then decided to rever to stock rom, I unrooted and did triangle away and flashed the rom my phone came with, problem still persisted.
Then flashed back to Omega 33.2 with full wipe and problem persisted.
Did a series of full wipe -> flash -> factory reset in OS -> full wipe -> flash -> factory reset, after which the problem still persisted.
Flashed Omega 33.3 today over top of Omega 33.2 with full wipe and format /system from CWM, problem still persists now.
Any ideas on how I can remedy this?
Thanks
Van
this might not be related but give it a try
-Try changing your WiFi channel maybe to 6? or 7
Try a different kernel try a different rom .

Hi, thanks for the suggestions.
I have tried already different WiFi channels and have tried 4 or so different ROMs and the siyah kernel. Have tried aosp and stock firmwares along with the Sammy based jellybean ROMs. Have tried cm9.1, stock 4.04, stock 4.1.1, leaked 4.1.2 stock, omega v33.2 and 33.3.
WiFi was perfect before my first flash of omega v33.2, immediately after the flash it was extremely poor and hasn't changed through all the ROMs I've tried since then.
Wondering if it could be somewhat coincidental and my WiFi module if faulty. I could reflash to stock and send for warranty but would only like to as my last option.
Thanks
Van

Not sure if it's the case with Omega ROM, but I had a similar issue with an AOSP-based ROM. Solution was simple: flash back to stock ICS ROM, connect to wifi, then flash back to JB ROM. NO problem after that. might be worth a try before sendning it back for warranty.

Thanks for suggestion, had tried that when the problem first appeared and it hadn't worked. Just went back and did it again, wasn't able to connect to WIFI on stock rom I9300XXALE8_I9300NZCALE5_NZC, did factory reset from within rom, still unable to connect. Rebooted to stock recovery and wiped data/factory reset, wipe cache and rebooted straight to downlaod mode, flashed stock ics 4.0.4 I9300XXALE8_I9300NZCALE5_NZC again which is what came on my phone. Still no go with WIFI despite having 4 of 5 bars of signal. I get the connecting symbol which goes for a while then changes to scanning and back to connecting again, meanwhile under the wifi network in question it just remains "saved, secured".
Just performing triangle away/re-flash stock once more to preapre to be returned for warranty.
Any other suggestions?
Thanks
Van
