[Q] no downloadmode and no network signal

hi can anyone help
i got my sgs about a mouth ago and thought that i would root it. i read up on it
so i rooted it to i9000xxjp2 2.2 which i thought was the lasted update then realised it was not so i went to go in download to do the lasted update but would not let me by the 3 button combo or by a jig the phone works fine itself apart from there is no network signal and can't connect to my pc but can connect to wifi
plz can any one help

Hi
try reinstalling the drivers through the program kies - see if the pc then recognize the phone.
did you try getting in recovery mode? you have cwm? you didnt say. if yes change the modem with a flashable zip ,that might solve the no signal.

thanks can not get into recovery or cwm but i can now see my phone in my computer but keeps saying connecting in kies

in phone go to settings -> applications ->develompment and enable usb debugging.
then you can connect to computer without kies.
youcan also try under wireless and network go to USB settings and choose "ask on connection"
does this helps?
did you try again to get into download mode with jig ?

i have tried it in debugging i can see the drives but when i click on them all it says is insert disk but i can go into them if debugging is turned off
and i have tried the jig several times now
if you need more info plz ask thanks
thanks for the replys
is there any thing else i can try

Hi
well there are the threads dedicated to the lack of download mode, you read them and tried it? (other then jig thread)

download drivers from perka's file stash. give it another go ...
i think you changed bootloaders and it messed the mods. but for this you'll need some with more experience then me.

hi,
If you want the 3B combo, you must flash the bootloader fix :http://forum.xda-developers.com/showthread.php?t=785201.
Check your drivers, cable (stock one) and if you, check wireless -> USB settings -> Kies mode selected.
About the network signal, check you EMEI (*#06#), if it's a default one, something happened to your /EFS folder (restoring a previous backup can, probably solve that issue).

[Q] Touch not working after update

Hi, please forgive my english.
My phone is a Samsung Galaxy Mini, firmware version 2.3.6 (stock). I was looking for codes to enter in the dialpad and I find the "update touchscreen firmware" code. I entered it and tapped "update", but it gave me an error code and now the touchscreen is not working.
I looked for a solution in this forum and I found this. I tried to follow the instructions but it seems that USB debugging is not enabled currently on my phone, so i cannot install google drivers and let the pc recognise my phone as an ADB composite interface.
I already tried flashing the firmware, or full wiping cache and data but nothing happened. Is there any update.zip package which enables USB Debug on the phone? All that I have to do is to make my pc recognise the phone as an ADB composite interface so i can follow the guide in the link.
Please help me, I cannot buy another phone, please..

you should take it to Samsung care

I9070 can't connect via USB after flashing rom:I9070XXLQG_I9070PRTLQ1_HOME

Hi guys,
I've successfully flashed today rom I9070XXLQG_I9070PRTLQ1_HOME (polish play). I was planning to send my phone on guarancy repair so they can clean dusted camera but I've lost my guarancy card so all that was for nothing anyway I've noticed that after flashing this rom I can't connect my phone via USB - phone is charging but doesn't show that my device was connected.
Tried reinstalling samsung drivers and few other fixes searched on google like turning off device, pluging the cable and then turning it on but without any effect.
I've managed to root device and install CM10.2 but it didn't fix the problem (I've copied files on memory card on another phone).
Anyone faced similar problem and know how to fix it?
Thanks in advance
All the best.

Turn on usb debugging in developer options. You might need to tap 7 times on rom version in About phone to get dev options.

Hi,
Thanks for fast reply,
I've tried that already - doesn't change anything.
Also phone is not visible in download mode.

I'd try:
- another usb cable
- another usb port (avoid hubs)
- another PC
- fresh system install
- another rom like anything stock based or cm10.1 maybe
what happens on your PC when you enter CWM and plug an usb cable

ok, anything happens in device manager, any new unrecognized devices shown there?

i have also had this problem from quiet some time and it happens with almost every rom for me:crying:
and temporary fix is
1) go to devices and printer(u will have ur device over there by its original name or as an storage device)
2)right click on ur device icon
3)select troubleshoot after some time it will ask u to apply fix
give permission after that it will install ur drivers once again n ur problem will be solved for a FEW DAYS

Hi again,
Thanks guys for your reply.
 @kunal19911 - sorry not working, my device is not visible at all anywhere
@adamuadamu as above - no unknown devices in device manager.

Yep, I've tried - many times - as written before tried to plug in in download mode - also no effect.
I've never had this problem before, is there any way I could flash new rom without estabilishing USB connection?

Huh, from CM10.2 you need to do it with Odin. Or to repartition preload partition. But I do not know how to do it.

AFAIK no need to repartition, but it's enough to format /preload (in CWM go to advanced - format /preload). at least worked for me when leaving 4.3 and 4.4 roms.

y dont u try flashing any other cm10.2 based rom with cwm?

The thing is that I don't have this issue because of CM 10.2.
It was cause since I've flashed stock ROM listed in the topic.
Flashing CM10.2 was a desparate try to fix it, after rooting stock rom, flashing cocore kernel didn't help.

Hello, I have the following problem. As in every other thing ive done to this phone (root, installing twrp, installing xposed) I always thought my model was LG-H502F. Though, my model is LG-H500F, I bought it from Greece, I recently bought Huawei P8 lite 2017 for myself and I gave my old LG to my father, he tell me that sometimes it lags and he is right. I think it lags because I uninstalled Xposed (flashed the uninstall zip using twrp) and also removed root, because he didnt need those things in his phone. The question is: Is there somewhere I can get the stock LG-H500F zip and what guide should I use? Ive been searching for a while now and can't find many topics related to LG-H500F. Thanks

Someone have link to stock for h502y?

No network connection on x522

Hello,
I have a problem on my father's x522. It ran out of battery and after a full charge it couldn't find any sim card. I've restarted the phone in fastboot mode and applied these commands:
fastboot erase modemst1
fastboot erase modemst2
After restarting the phone both sim cards were working, I could insert the pin numbers, but the phone couldn't find any network (wi-fi was fine). I've noticed that the IMEI numbers were gone so I've restored them using QMSL IMEI & SN Writer, but still the phone couldn't find any network. I've also tried to find netowrks manually but I kept getting this error: "Error while searching for network".
I've tried to flash new roms (the phone was on a stock 23s if I'm not mistaken) and modems but the phone still has the same problem. Right now I'm on a Small EUI by Ariel, the baseband is mpss.ta.2.1.c7-00008-8976_GEN_PACK-1.64611.1.68083.1
What am I missing? Is there any way to make the phone working again (before telling my father to buy a new one...)?
Thank you.

Hi, I have the exact same problem, did you manage to solve it?

my problem is the same try everything all in vain decided to to open up my phone found that the antenna cable is to near the screw and it is squash so that is how i solve it by tucking the cable away from the screw area.mine is new btw changing diferrent sim also did not help so my problem is hardware.

No.
I've tried everything, ROMS, modems, QCN backups, voodoo rituals, but still this phone doesn't connect to the mobile network.

I think I solved it by doing these steps:
1. Put the phone into Airplane mode (I'm not sure this is needed, but it doesn't hurt)
2. Go to Settings -> About Phone and tap on "Build Number" until it says you are in Developer Mode (~10 times)
3. Go back one menu, and right above About Phone there should now be an option for Developer Options, go into that
4. Turn on USB Debugging
5. Connect the phone to your computer and type "adb shell" in your CMD window
6. Run the following commands in adb shell :
pm clear com.android.providers.telephony
settings put global preferred_network_mode 9
settings put global preferred_network_mode1 9
settings put global preferred_network_mode2 9
7. Turn off Airplane mode
8. Power off and Restart the phone
9. Open up the settings app, go to the mobile networks panel, select "Preferred Network Mode" and change it to "4G"
10. Input the appropriate APNs for your specific carrier
You can try other modes, here's a list I found: https://android.googlesource.com/platform/hardware/ril/+/master/include/telephony/ril.h#228
I hope it helps.
