Hi everyone, first, this is my first post, new to the forums, at least as a registered user. I have a problem with my phone. I know most of you are wondering why I have not just read the other posts on the forums, but I have. I have attempted every solution to the problem posted previously.
Background: Phone: Samsung charge.
I was being impatient and did not want to wait for the gingerbread update form Verizon. I flashed the leaked gingerbread 2.3.4 onto my phone using odin. Everything went great. I was able to use my phone with no problems except shortened battery life, but nothing major. About a month ago the battery life was impossible to maintain and there were some software bugs, like clicks during calls, startup taking forever, around 2 minutes on average!, and random restarts that never happened before. I decided to look up some fixes and found that verizon and samsung had released GB 2.3.6 for the charge. I got excited and decided I wanted to get that, but I could not via OTA. I read some forum posts and they mentioned attempting a factory reset on the phone then trying OTA update. I went ahead with factory reset and everything went fine. My startup time is around 25 seconds now and no random clicks or gliches, but still not on 2.3.6, which was the whole point. I then decided to just flash the stock 2.3.6 rom to the phone.
Problem: When I plug my phone in to multiple computers it will charge but not connect to the computer. This means on my Mac it does not show as an external drive, which it has in the past. On my windows 7 machine it says that drivers were installed but could not be used (I can get the exact quote if needed.) I attempted to go into device manager and solve problem that way but it shows my phone as "unknown device". I have tried to enter download mode when hooked up to windows computers and no connection is found.
Possible solutions attempted and their outcomes:
1. As stated, I attempted the method shown in a thread on droid forums for installing the samsung drivers. I have attempted multiple times to install the drivers on my windows machine and the device remains "unknown".
2. I have attempted multiple cables on multiple computers, both mac and windows 7. No change.
3. I have installed adb and attempted to locate devices using adb devices command on mac. No devices found.
4. I have attempted all methods with both usb debugging checked and unchecked.
5. I have tried every possible usb port I have.
Ideas/questions I have had that I have no idea are possible or how to fix!
Would a factory reset take away the ability to connect to a computer from my phone. So, is there a piece of software in the build I have that controls the connection between the computer and the phone, an identifier of sorts, which is now missing, now that I have reset the leaked ROM.
Is there a way to flash a new ROM without connecting to a computer, via the sd card, and what is that? I have read some things in other posts but am too much of a n00b to understand most of them when using sdcards.
ANY help will be greatly appreciated. PLEASE PLEASE PLEASE!!! I have been at this for at least 6 hours, sifting through forums, searching google, attempting fixes that others have stated worked for them, only to fail every time. Thank you all.
i've had a few issues with this on my Droid Pro. with windows connection a connection assistant came up with some options that I was able to get it to work as a drive.
Getting it to work with adb is another issue alone. The phone needs to be in "debug" mode. I would search for a tutorial on this because you need to edit files on the computer.
for example on my windows I needed to edit one set of files, while on my linux I had to edit another set of things.
I leave my phone in debug mode because i use it for my android app dev on both computers. try that and see if it shows up on your mac.
I have a Samsung Proclaim that kinda works... I have StraightTalk service. I have searched and searched for 2 weeks now trying to fix this myself. I am too new to Android to figure this out on my own. If some one else has already had this issue please point me in the right direction, I simply cannot find it.
Symptoms:
No Wi-Fi
No Wireless tether
No USB SD card write abilities
No Auto Rotate (maybe no rotate at all)
Intermittent USB Tether
What I think I need:
Stock Rom
Here's what happened:
3 weeks ago I turned on my unrooted phone to be greeted with an OTA system update alert. I clicked install. After my phone reobooted Fox-Fi would not work. I then tried copying all my data to PC to do factory restore to find my SD card shows up as a CD-Rom and I cannot modify files. I found workarounds for this posted on various sites but none worked. I backed everything up to SD then used a card reader to move to PC. I tried a factory reset which completed successfully but changed nothing. I then tried to root my phone using shabbypenguin's method and it appeared to work but then I lost the ability to auto rotate my screen in several places and I lost the ability to connect to Wi-Fi. I installed several different USB tether programs and all of them had issues connecting and staying connected.
I have access to another proclaim that is unrooted and not updated, but it belongs to a co-worker. I dont want to risk damage to his phone by rooting it. Is there any way I can make a rom from his phone without root or does anybody out there that knows of a stock-ish rom I can download? Would I be better off just sending this phone to StraightTalk?
I really can't afford to replace this phone for several more months so I really need it working again. Any help given is greatly appreciated!
Somebody please help! Don't make me drown my phone!
Basically what had happened was I was out on Friday night, drunkenly gave my phone to my friend to keep safe, and then totally forget about it. Fast forward to me panicking and immediately setting a password lock using Android Device Manager. For some reason when setting a password remotely from your PC it can be as long as you want, but when typing it in my phone there was a limit, meaning I could not get in.
Why don't you just use ADM again to reset your password and put a new one?! Well apparently they don't let you form a new password once there is one already locked on your phone. Why don't you try unlocking it via findyoursamsung?! I didn't create a samsung account when prompted to. (hindsight is 20/20)
I also tried some other third-party backup apps such as Kies3 and Samsung Watch, both of which required the phone to be unlocked to function - which is also why I can't simply just connect my phone via USB and drag the data into a folder.
This lead me to doing a ton of research and it seemed the only way to get my pictures and videos back without resetting my phone would be through those coding programs and ADB and such. I am not well versed in this area at all so I looked at a bunch of sites explaining what to do.
From my limited understanding, it came down to a few things:
- My device is a Samsung Galaxy S4, probably kit kat or jelly bean. It is neither rooted nor does it have the "USB debugging" enabled
- I have successfully installed CWM (clockwork mod) and ADB (android debugging bridge) onto my computer/phone because apparently when CWM goes into recovery mode, the debugging is automatically enabled, where I'd then be able to unlock the screen (but I don't seem to know how to input adb commands - where would I do this?!)
- I installed a few other programs that were of no use to me because I had (almost) no idea how to use them (Cygwin, Odin, JOdin3, Heimdall) in conjunction with ADB and the "Download" mode on my phone to flash CWM to be my "custom Recovery" instead of the stock recovery
- I saw there were some third party apps that would automatically (?) unlock your phone screen for you but I wasn't too keen on trusting them seeing as most of thm were outdated , so unless you guys recommend one I would rather not download those
- I think my main issue is not knowing how to simply bring up a terminal and input commands but sometimes they wouldn't even recognize my device (probably because USB debugging is disabled)
I have been infront of my computer for almost a whole day now trying everything and reading everything simply trying to figure out what to do. I have looked at way too many guides and could probably recite them to you. I guess the point of this is I really would prefer not to lose this data as it has a lot of sentimental value, so I'm straying away from those methods that require you to wipe your phone. If any of you know any helpful sites or guides (I probably have seen them) that explains things very formally and easy to understand, let me know, I will be forever gracious for your help.

Hello, and welcome to XDA!
A bit of a doozy....
This thread may help:
> Samsung Galaxy S 4 i9500, i9505, i9505G, i9506 > Galaxy S 4 Q&A, Help & Troubleshooting > [RESOLVED] HELP please!! Unable to unlock device locked by Google Device Manager
May need to modify solution two to use under CWM. That is, mount data via adb (or via recovery if there's an option) before issuing (the rest of) the adb commands.
By the way, here is a primer to adb:
http://www.xda-developers.com/all-in-one-guide-to-adb/
Hope this helps, and good luck!
I'm at a point where i need enough help that im starting a thread about it.
How it started:
It all started when i restarted my G5 with Quick Reboot [ROOT] (AntaresOne Studio ) because it was lagging/slow.
After restarting the phone would not boot. It would always go to the Optimizing XXX of XXX apps, finish, restart and optimize again.
What ive tried:
I factory reset my G5 by using TWRP and formatting the data partition.
That allows me to use the stock? G5 ROM, but one huge issue, is that if i turn on Wifi, the phone reboots within 2 seconds to the tmobile screen and gets stuck.
It fails to reboot after that.
My phone has retained root. I was able to verify that by downloading Root Checker and it confirmed that i have root.
SuperSU also worked properly and SnapChat fails to login because it is detecting that i still have root.
I have been rooted for several weeks without any problems fyi. I have not updated my phone at all.
I was hoping i could unroot and flash the stock unmodified? tmobile ROM,
but in download mode, LGUP detects the device as "unknown device"
and if the phone is booted, LGUP does not detect it, instead it gives me a drivers need to be installed warning.
(The drivers are already installed, because i installed then when originally rooting, i also reinstalled everything the root guide suggested anyways)
At this point i am clueless as to what else i can do.
Currently i can use the phone more or less fine but i can only run on data.
Play store has trouble installing apps via data so i tend to download and install APKs directly via file manager.
Thank you for any help and insights in advance.
Well, I would suggest flashing the 10D kdz to get back to stock. However you need LGUP working to do that...
It sounds like a driver issue... I would uninstall the driver, reboot, reinstall, and try again.
As for uninstalling the drivers, that is easier said than done sometimes. You may need to manually remove the driver files if the uninstaller does not.
You may want to use something like Revo Uninstaller to monitor the install and then do an uninstall again.
If you have another computer, doing it on that computer could be an easier route, heh.

SO i tried it on my mom's windows 7 desktop, and it look slike all the drivers installed properly, however when i run LGUP, same thing happens.
It shows up as "unknown device". The other LG software also doesn't detect it. I can factory reset the phone and it stays rooted, but the broken wifi is a huge issue.
I'll keep try thou. Your driver issue idea seems valid but idk what is happening at this point :/ I used to love this phone and LG (coming from the S4) but no so much anymore...
The chinese brands will take over at this rate lol. Axon 7 is compelling. Again, Thanks for the advice
EDIT:
I fixed it. Issue was due to build.prop. because the file was modified it caused the software to not detect the phone properly apparently, so putting back a clean stock build.prop allowed LGUP to recognize the device.
In order to keep this thread clean, please use this one to discuss about Development, Support or Software Updates.

Hi, I'm using win 7/32 and I did not need usb drivers. We restarted the windows, in F8 I turned off checking the drivers' signatures and then started the windows. On the phone I enabled the developer options and the usb troubleshooter. Then I plugged the usb cable (on) to the computer. It will start downloading and installing the drivers. You have to run all the options for connecting the phone to the computer (usb configuration), from simple loading to MTP, PTP and MIDI. When all the drivers have been installed, restart the computer and turn off the phone. At me, (Cubot x 18), I have not removed any battery, neither sims nor microsd. Just with the phone off. When you restart your computer, start the sp flash tool, choose MT6737T_Android_scatter for what you need, choose the option and activate it, and finally plug the phone off to your computer. From now on, everything has to go ... That's the method I use. I was frankly amazed that she was running without a battery in the phone; and all the way to him, just stopped.

Hi just got my phone and the mobile data is disconnected. I cannot turn it on and when I try to go into phone settings and try and change the radio band it crashes the application. The option to enable mobile data is there but has no effect. Anyone know of a fix or maybe how to download a new modem? Tyia
Maybe this ...

Hello, I think you need to set a new APN. To do this, you must go into Settings-Wireless & networks-More-Cellular networks-Access Point Names. At the top of the bar you will have to press "+" and you will need to configure the new APN according to the mobile phone operator from which you have the SIM card you are using. Once configured, you'll need to save and check it as an asset, the one that your phone will use. That's all. And there would be something else. At my side, I can not catch 4G, it gives me connection error. So I set it on 3G, from -preferred network type. Hope to help.

Thanks mate. The correct apn had been set and it shows 4g connection at the top but simply refuses to connect to mobile data. It all says its switched on etc. When I type +*+*4636*+*+ into dialer screen to bring up phone settings it is there that it says mobile data disconnected and it simply will not switch on.
I've also factory reset the phone and it won't connect to mobile data then either. When I try to change the radio band it crashes.

Wi-fi going? Perhaps there is something on / off in your phone that limits your access to your mobile data network (billing cycle, data usage, roaming, or anything like that). Frankly, my knowledge is limited, I do not know what else it could be. If wi-fi works, try updating it, you may be lucky.

Thanks mate. Nah me neither. WiFi does work but no joy with mobile. There's no update available and a factory reset never cleared it. I think the issue lies with the radio band. It simply crashes the application whenever I try to access it.
Not receiving incoming calls when in VoLTE
Since my carrier is activating VoLTE through its network
I cannot receive incoming calls. If my phone receives only the 4G signal (without VoLTE) the phone works perfectly. I tried another sim card of the same carrier...same issue! If I put on the phone a sim card from another carrier it works fine, but I think this carrier is not using VoLTE yet. Using the *#*#4636#*#* menu I switched off "provisioning VoLTE" option...but after a few seconds it turns on again automatically. I do not know yet if the problem is linked to my phone, carrier or a problem on Android. Does anybody can help me? Thanks in advance
PS: my phone is running native Android 7.0 and it is updated with the latest firmware version
Try a drastic solution. Reflash your phone. The problems are with MTK firmware structures, MTK firmwares usually results in lost IMEI or NVRAM issues.
I am a fan of anything MTK phablets, tablets, phones and owned mostly Lenovos about 7 devices, all rooted with TWRP. My advise is to reflash the phone (since we already have the firmware), if it doesnt work the first time after reflash , you probably need to reflash a few more time and you will find that after every reflash there will be random functions and apps broken (after the next reflash the functions and apps are OK but others broken) until you will have all 100% OK. That is my experience with MTK SoC.
Good Morning!
Can you tell me if this procedure works on the new model, the P20? Uses Oreo 8.0.0 with Kernel 3.18.60 ...
Thank you very much
Me too

Hello guys,
I've the same problem with my X18. Everything works fine. My SIM is active and registered and in the notification bar there is a 4G-icon, I can make some calls, receive SMS and so on. But if I use mobile data, the connection will be interruped after few minutes and in the settings dialog the SIM card is disabled.
Reboot, changing SIM slot takes no effectes. This error is reproduceable.
The device has 3 APN-Settings. Is there any oppurtunity to delete these settings, so that I can receive new APN from my provider or to define it manually?
Best regards
Dan
Good review thanks..
