[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] graydiggy:
Your signal is shoddy because of the solder. I highly suggest not modifying the antenna as that could make things worse. I would replace the entire board that that piece sits on. Or grab the connector off of a broken/ phone and replace that.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] skabg:
Well, in this case I have to replace the whole motherboard, as this connector sits on it. I have the same connector and can possibly un-solder the old one from the board and put the new one.

Does really the little bit of solder can mess so much with the signal quality?
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] graydiggy:
Yep. The connector is copper. Solder is composed of nickel and lead normally. Having 2 or more different metals messes with the conductivity.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] skabg:
You might be right about that, but that small metal piece acting as a connector isn't made of copper for sure, it looks like it, but it is attracted by magnet, that's how I soldered it back into place. Based on my knowledge copper alone isn't attracted by magnets, so it has to be some sort of a mix of metals. Isn't the connector soldered to the motherboard anyways? It just bugs me how big of a difference this would make.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] graydiggy:
It is copper coated. They solder used is very thin on the motherboard. It has a very little affect to the signal. When you add more, it messes things up.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] skabg:
Interesting, any suggestions of how to remove the broken piece from the board and re-solder the new one? Seems like solder gun will be out of the equation.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] graydiggy:
15 to 25W max soldering iron. A thin layer of solder on the new part. Set it on the pad, heat it on the top of the contact surface of the new part till it joins. You should be good from there. Be careful of surrounding parts.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] nthknd:
You guys are amazing. I would have broke down and just replaced the phone.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] graydiggy:
I've been doing small electronics repair for almost 11 years. Its easy for me. Just gotta be patient and careful.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] nthknd:
Yep that's my problem....that patient thing just not my cup of tea.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] graydiggy:
I used to be like that. Then I realized how much stuff I stopped breaking by being more patient with it. Now i can do a project just as fast as I used to want to, without all the frustration. Learning this stuff takes time.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] skabg:
Yeah, patience is my problem sometimes as well, I figure that might have caused the broken connector now, the impatience and frustration with the signal not showing up. I was able fairly easy to un-mount the same connector from another board, but soldering on the motherboard will be very difficult for me, as I don't have such precise soldering gun and tools to re-attach it on the board, it seems nearly impossible from my point of view without them.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] graydiggy:
If you were able to get the piece off, use what you have to put it on. Won't take much time.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] skabg:
Getting it off another board is easy, just heat up a bit and it comes off, but getting it there needs more precise tools. It feels I need to just heat the metal connector and place it on the board so it can just melt the solder and stick on it.

The iron I use it's just not meant for these tasks.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] graydiggy:
Welp, see if someone you know has the equipment.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] skabg:
Well, the problem seems to be somewhere else, coverage is low, we replaced the connector and it is exactly the same situation, I seriously doubt it at this point that the problem was excess solder on the connector. Connector is replaced now, no excess solder, signal strength remains very bad.

On some occasions signal improves to where it is suppose to be and then gets lost real quick, so i has to be something I'm not seeing and simple. I'm exhausted at this point and I maybe overlooking something.

Any advice would be very helpful, the only other thing I can think of is the rear housing panel, where the antenna is located to be damaged somehow, but it's antenna, it used to work well before I cracked the screen.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] graydiggy:
Try bending the connectors up just a bit. They may not be making good contact.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] skabg:
I did that already, that's probably the reason why one broke the first time. They do make contact, just because when I bend them and then later remove the rear housing, they are pressed back.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] mfc719:
Same thing happened to me. Just found out I did something really stupid. On the new frame where the flex cable for the home, back, and menu buttons connect to the USB flex cable that has the bottom antenna connection, there is a white piece of protective tape on the underside that I did not remove. (See attached pic). Works fine now. Stupid stupid me!

For some reason, I am unable to flash cyanogenmod based roms.. I am using a T-Mobile S4 Unlocked. I am using the latest CWM. I have attached a picture of the errors. Any ideas? I haven't tried anything because I am even sure what direction to go in.. I have installed CM roms before.. Right now I have the Google Edition 4.2.2 Rom from Jamal installed.
[Galaxy S 4 Q&A, Help & Troubleshooting] Obagleyfreer:
You need to update your recovery to CWM 6.0.3.3
[Galaxy S 4 Q&A, Help & Troubleshooting] svfusion:
Thank you for your reply. The latest I can find is 6.0.3.2 for the S4.. I have searched this forum and google.. am I missing something

Sorry, I found it.. It isn't listed as T-Mobile and just 9505 :)

[Galaxy S 4 Q&A, Help & Troubleshooting] bofff:
Is it possible to convert I9505 to i9505g?. Especially to make repatriation sdcard?
[Galaxy S 4 Q&A, Help & Troubleshooting] hmsq:
Plenty of threads about this already, but here you go, no there is no option to do this yet.

Please search before your post.
[Galaxy S 4 Q&A, Help & Troubleshooting] illogic6:
I have the G variant. Honestly, you're better off where you are. The I9505G has a very small system partition, so we can't flash Touchwiz ROMs even though the hardware is identical otherwise. I can get Touchwiz to boot, but that's with almost all system apps removed. If you start to push the system apps, you get a partition full error before you even get a 1/3 of them copied.
[Galaxy S 4 Q&A, Help & Troubleshooting] Cozmo85:
Hopefully they solve the 4.3 OTA issue on i9505 variants.
[Galaxy S 4 Q&A, Help & Troubleshooting] bofff:
I v red some of them. Unclear imo. Where problem lays? Impossible to flash Google bootloader or convert Google pit file to be compatible with Samsung one?
[Galaxy S 4 Q&A, Help & Troubleshooting] MichelN:
Tried to flash with a full odin image ?
[Galaxy S 4 Q&A, Help & Troubleshooting] illogic6:
You can see what I've tried in the first post of this thread: http://xdaforums.com/showthread.php?t=2393760

I haven't flashed with a full Odin package yet. I suspect it would fail, but am willing to try anything at this point. Has a full Odin package been created?
[Galaxy S 4 Q&A, Help & Troubleshooting] MichelN:
I mean flashing a Odin image from the i9505 on a i9505G
[Galaxy S 4 Q&A, Help & Troubleshooting] bofff:
?? Is it possible? Different bootloaders as I red. Different pits. Isn't it my case but just reversed?
[Galaxy S 4 Q&A, Help & Troubleshooting] Noorish:
I don't get it, is the limitation for converting the i9505 to G a software or hardware one?

I keep hearing different reasons, some say the partition layout, some say the PIT file, others mentioned the lack of a full Odin package, those are all software?

If the hardware is identical, wouldn't a full image from the G taken and installed on the i9505 work?

I still don't get it :/

Just to add confusion, Alex here says he managed to install the GPe edition on his Galaxy S4.

What am I missing here? http://www.androidcentral.com/samsung-galaxy-s4-three-months
[Galaxy S 4 Q&A, Help & Troubleshooting] bofff:
Yeah. Full, Odin compatible, image should end this story. Pit file is one which create partitions, but somehow ge pit is not compatible with Samsung bootloader. Correct me if I'm wrong
[Galaxy S 4 Q&A, Help & Troubleshooting] Aerys:
True.

You can flash system,recovery,boot,CSC from I9505G on I9505. You cant flash modem,pit,bootloader.

The bootloader is protected and wont allow you to flash different,custom modems and bootloaders.
[Galaxy S 4 Q&A, Help & Troubleshooting] dryspuri:
Thanks for the info

But thats not fair, HTC one can be easily converted to GE, but I agree u need s-off for that, we have been critisizing HTC for s-on, s-off for quite long time, now samsung is doing it without even declaring and there is no way to change that!! I think sgs 4 is bigger community, but all the devs( serious) ones, no disrespect to devs here, are in HTC community. I recently shifted from HTC, but was disappointed about this move from samsung!!

I was so looking forward to convert i9505 to GE, as they are not selling that in here. shame on u sammy:crying::crying:

Hello I'm sure there's a thread somewhere but I'm curious to what battery life ppl are getting from their 4.2.2 roms.. I'm currently using beanstalk with moderate use I average 8-10 hours.. What's your average battery life and using what ROM?
[T-Mobile Samsung Galaxy S II SGH-T989] I opus l:
Sup dude, I've been switching back and forth between thedude's Hellybean and clkener's Liquid black. Both rock solid Roms. I generally tweak my Roms the same and usually get at least a day of battery from them while listening to music on my sd card at work for 5-7 hours a day. On the weekend when I don't have to deal with work calls and no music I'll get anywhere between and 32 and 40 hours. View attachment 2167426
[T-Mobile Samsung Galaxy S II SGH-T989] gabriel1946:
Dam that's way better than what I'm getting what tweaks did u do
[T-Mobile Samsung Galaxy S II SGH-T989] I opus l:
First thing I usually do in a new flash is install Trickster Mod and set min and max clock speeds to 192 and 1026 MHz respectively. Sometimes I'll shoot the max up to 1200 and change, but most of the time I'm fine with 1026. Then still in trickster I'll go to mpdecision and turn the idle_freq down to 192.

These are from ClKener. Go into voltage settings and and drop all the settings by 200000. (This is generally a pain in the ass but at least you use the overall controls on the top, but you still have to tap it a couple of hundred times) Change the governor to ondemand and the scheduler to bfq. Make sure you set it to set on boot.

I also use the app Llama. I have it tuned so generally my mobile data is off and network is turned to 2g (you can still make and receive phone calls and text messages in 2g). At home my WiFi automatically comes on, but soon as I leave in the morning the WiFi is turned off. And when my screen comes on away from home, then 3g+2g is switched on and so is mobile data. My screen is almost always set to 0 brightness. I think that's all of it.

Battery life reduction issue? blame Project butter. I might sound stupid but try android 2.3.x and you will easily get 4 days I bet.

Im atm using Carbon rom 4.2.2, By I am the forst. and normal usage im getting 2 days easily also OC to 2Ghz and governor at interactive.

I will recommend you that rom.
[T-Mobile Samsung Galaxy S II SGH-T989] angler_fish:
Ya, I agree. After they had the Project butter thing, my phone's battery went from at least ~12 hours to around ~8 hours. I have been jumping from ROM to ROM since CM7, and I have to say, once we got up to Jellybean, battery life went a step down.
[T-Mobile Samsung Galaxy S II SGH-T989] gabriel1946:
Yea Idk but I'm using helly bean and Ive barely used my phone and in 2 hours its at 78% i really want a smooth ROM with great battery performance.. Maybe im not lettin the rom sit in long enough its been about 2 days.. It deep sleeps fine and i keep my data on cause i need it for work i hear ppl getting two days out of their battery which is crazy too me i barely average 8 hrs.. Would go to gingerbread but i hated the interface and i could tell the perfornance wasnt up to par.. Ita not a app isue either unless its a system app? Also gps is off never use it thanks for your replies:D
[T-Mobile Samsung Galaxy S II SGH-T989] mpalomba3:
Try doing a factory reset. The galaxy s4 had a battery problem with the new MF9 update and a factory reset fixed all issues.
[T-Mobile Samsung Galaxy S II SGH-T989] HQuser:
Also If you're using CWM try running darkside super wipe, and if TWRP try formatting preload too before flashing. GB lacks Project butter which means laggy UI and animations. But if you want little of both try ICS best after GB. And if you want to stay latest Give Carbon rom a try by I am the forst you will see huge difference in 1 try. also do not forget to callabirate battery after new freash install of rom.
[T-Mobile Samsung Galaxy S II SGH-T989] gabriel1946:
I've factory reset my phone seemed to of worked for a bit but after flashing another ROM it shortened the battery life

I'm on twrp u mean wiping the preload? And I read that battery calibration was a placebo so I quit using it and the battery is fine if I flash a tw ROM I get crazy battery life. Imma give carbon a try and calibrate battery
[T-Mobile Samsung Galaxy S II SGH-T989] bikeryder007:
For the record, I got 5 full hours of screen time yesterday on Hellybean, and that was with the regular clocking and my screen brightness set on automatic. Most days after using my phone like normal, I will put it on the charger with 40 to 50% left. Are you going long periods without a signal or something? If I do that cell standby eats my battery.
[T-Mobile Samsung Galaxy S II SGH-T989] gabriel1946:
I envy u lol I just got off work with battery at 65 percent I've used it for about 30 mins screen on and its down to 42 lol and na signal is cherry I get perfect signal with all ROMs where I am i think im screwed or somethin i even have underclocked to 1200 and under voltage by about 10000 bfq/ conservative lol :confused::crying:

Ran it for 6 hours seemed average on my battery but tried slim build 8 and wow fell asleep with it oc'd to 1800 everything was maxed out I was benchmarking with the screen left on for 3 hours and its barely at 83 % and this is my benchmark score im using uber kernel of course this ROM looks very hopeful also I factory reset clean installed this ROM and calibrated the battery

[T-Mobile Samsung Galaxy S II SGH-T989] gabriel1946:
Its too much effort to go to 200000 just for it to crash like it did me personally I think 50000 is good also I am getting crazy battery life from the slim ROM build 8 my new dd it doesn't have halo which sucks but that's the only down side.. No echoes in call and also ppl I have talked to say I sound really clear
[T-Mobile Samsung Galaxy S II SGH-T989] jason4962:
Besides the 50000 undervolt did you change your kernel or governor. I have blackliquid . stock kernel on ondemandx governor. Becuase ondemand will cause problems. Getting not good battery life.
[T-Mobile Samsung Galaxy S II SGH-T989] gabriel1946:
I slap uber kernel on all my 4.2.2 roms.. I did a lil tweaking I only under volted by 10000. Under clocked to 1280 using cfq/Wheatley i also did a super clean install in twrp i wiped cache, delvic cache system, android secure and preload flashed over radio, rom, gapps than kernel been working like a beauty so far and this slim build is going well i switched from black liquid it seemed a lil unstable and had frequent crashes and poor battery life. Im anticipating 4.3

Flash away but then try to stick with one rom you like for a week or so. That would be enough time to get the battery working.

Charge to the full, drain completely. Do it a couple of times. That will be enough.
