[Q] Lg Optimus 2x p990 baseband and driver issues.

Hi guys. Love this site but I am encountering some issues! I am having problems with the drivers (it appears), of my p990h. I am new to android (only had my device a week), and have duly thrown myself in the deep end to try and make the most from the device and have encountered some issues. I am in Colombia and bought the phone here. I ‘rooted’ the device using the ‘Super One Click’ method and had no issues. I then performed the fatory reset and installed the ‘Cm9.0.0-rco-p990-unofficial’ rom (build [email protected]). I didn’t experience issues up to this point. However (and i know i messed up here), i then flashed baseband version 1035.21_20110725 using smartflash. Big mistake as then the time on the phone changed all to European time, and now although the device can be read by my computer, it cannot connect to it and a yellow exclamation appears on the device in device manager. I have tried everyway to update this, but no joy. Tried reflashing with smartflash, but now nothing happens when the phone is connected (nothing appears in the ‘coms port’ box). If i use the lg tool, it doesn’t even list my p990 as a device whose drivers i can download.
So basically I would like to know if anyone can help me:
a) get the drivers working properly again so I can connect the device and update.
And
b) if anyone can get me the 1035.21_20110602 baseband files to go back to how it was previously. Have looked everywhere but no luck. I downloaded one, but i cant seem to find a way to use use it (it appears as a clockworkmod folder and macosx folder. I haven’t used them as i couldn’t figure out how!
May i need to re-root my device, could this be the issue? This had occurred to me that the superuser settings may have something to do with this.
I also want to be able to restore my phone to its stock settings as i really need my camera back up and going properly whilst here in Colombia.
I have spent the last week trawling these forums reading everyone’s posts and learning from you guys, so a big thanks out there to you all who have got me this far – many thanks. Seems like a great community and im looking forward to getting more involved, and learning about the murky waters of android (even though im having some difficulties i love it!) . I apologise for any poor wording and general noobiness that may cause any misunderstanding! I will try and answer any questions/replies i may get as accurately as possible.
I really hope someone can help me as I cant keep going in circles – i have a 12 hour bus ride tomorrow so gotta get it done.
Many thanks in you lovely people!

try flash a new rom CM7

[Q] Android M - Notification and Syncing Issues

Hi folks, I know what i'm doing, so I flashed the images and it all worked...BUT some major things are missing. I cant drop down the notification drawer (nor do I get any notifications) Also, nothing Google syncs. I tried manually syncing/logging out and logging back in and nothing seems to work, so 1) Suggestions? 2) Is there a dedicated forum for this? I cant seem to find anything online. I also tried flashing it again and to no avail.
Help me XDA, you're my only hope to not going mad on my phone.

Try downloading the image again and use the back ports, the ones directly connected to the motherboard. If you can't fix it and/or find an answer anywhere, remember that android M is beta; report it to the android developers and wait.
Just some personal history on this kind of occurrence (tl;dr some times the same hardware can behave differently on the same conditions):
My brother and I had once the same phone, the LG Optimus 2X. We bought the same phone, at the same store, on the same day, a promotion; quite the upgrade from my motorola milestone (droid). His would always have problems with custom roms that mine never did, some times was the other way around, but the developers fixed over time given the pertinent logs. It also happened Installing mac on my assembled pc, I got to have problems other people with the exact same hardware configuration never did and I didn't had problems that other people had.

Thats a great idea! I'm using a laptop so I will change ports. Does it make a difference when it says that ...exceeded maximum size... or what ever it said, id that normal? Update should be out this week I think as well!

Problems with phone after OTA update (FIXED!)

Hello,
I wanted to share what I had to do in order to fix my phone after it took the July 27 OTA update. The update somehow corrupted my display and the white portions of the display were now pink and red. A google search has info and pics on this display problem so I won't elaborate on it. The first thing I tried was power cycling the phone, the red and pink remained. The next thing I tried was factory reset the device, that didn't work either. I simply wanted to revert back to the previous firmware and hopefully that would fix it. I liked the new firmware features, but that pink screen had to go! I foolishly flashed the US unlocked firmware (XAA) from SamMobile site with Odin. The pink screen probem was fixed but this definately was not the firmware that came on this phone. Gear VR didn't work, Samsung pay was borked, and there were all types of problems with the software.
At this point I called Samsung Tech Support. The guy was really nice and after a bit of explaining he offered to have the phone flashed at no cost to me. However I would have to send the phone in to be repaired and I would be without my device for a week at least, maybe 2 weeks. I thanked him and hung up. Why couldn't he simply make the firmware available to me so I could fix this without having to send it in and be without my phone for over a week. Not really a acceptable solution. I went online and did some reading. That's when I found the fix!
To anyone who is having problems and would simply like to get back to original factory firmware Samsung has a program called " Smart Switch ". It's available as a App for your phone or as a PC software program. The phone app helps sync devices, but the PC program can do much more. I'm not going to go over in detail how to use the software because a google search has videos and tutorials on how to use it. For me I was able to enter my phone model and serial number and Smart Switch went and downloaded the "correct factory firmware" and installed it to my phone. Now I have the latest firmware (7/27) full factory install and the pink / red display problem is gone. So what I'm getting at is if you are having problems after taking the OTA update like I did, you can try using Smart Switch and install the complete factory firmware from scratch to your device. Make sure to follow instruction on how to use the program, I had to put the phone into download mode for it to work for me. Also be sure you understand about "Google lock" before flashing your phone. This program claims it can un-brick a Samsung phone, and will also over-write a rooted phone to get it back to stock. I'm sure Smart Switch has been discussed before, but for a new Samsung user (like myself) it sure got me out of a bind!

Hizpo Headunit with inverted screen

Hello everyone. I’ve got a hizpo stereo that a friend of mine give me a few weeks back. The numbers on the side of the radio is ADY17009. It’s running Android 7.1.2. The problem I’m having with it is the screen is inverted. I’ve tried the reset button tried erasing everything no luck. I tried accessing developer mode pressing build number 7 times and it didn’t let me access it. Anyone know where I can get a copy of the stock firmware and operating system on this thing or can I upgrade it to the latest and hopefully it will fix the issue. I can’t sign up on hizpo website. Every time I try to I get a connection timed out error.

Anyone?

[Help Needed] My Shield K1 has been hacked

Hello there,
First of all i have to warn you that i am a kind of a complete newbie about most things you are talking about in this forum. So please, be indulgent.
Also, i'm french, so english is not my mother tongue but, i'll do my best, i promise
I have knowledge in computing but not very much on tablets, phones, etc...
Here's what have happened to me.
Some months ago, i was looking at my tablet (Nvidia shield K1) when suddently it litteraly comes alive without me doing anything.
As i've some computing knowledge it was obvious that someone else was controling the tablet.
So i swith it off using the turn off button. Then i swith off all my network (router and modem), switch back on the tablet and disconnected it from the network. Then i turn back on the network.
The tablet was not anymore linked to the network.
So i start searching trying to figure out what was the problem.
But, as i said my knowledge with these devices is not very good.
This is were my memories are not really accurate as this happened to me a few months ago.
I first decide to ask some help to some people with a much better knowlegde than mine. I gave them the tablet but, they gave it back to me saying that there was no problem. They even upgraded the OS from Android 6 to Android 8 by downloading the update.
So i thought my problems were over but, in fact, they were not.
When i get back my tablet i tried to go again on the internet and didn't succed.
Once i have entered the password for my network, the network appears to be registred but i can't log on it..
So i started to search again for the cause of the problem, after a few hours, i found on the SD card 2 files that weren't here the last time i took a look.
These two files were named :
- Cryptokey
- Systemcrypto
Can't remember their extension....
So, from this point, i knew the solution of the problem was out of my reach as there was probably somewhere inside the tablet some corrupted datas.
This is where i definitely made a big mistake.
First i made a hard reset of the tablet with no results.
Second i have formated the SD card where two files were saved...
Now, i own a tablet with which i can't connect to the internet at home. But, i m quite sure that if i want to connect to another network than mine, it will work. As the guy to whom i asked help first succed to connect to his network and do the update to Android 8.
So, if anyone has an idea of what could i have to do to get back a working tablet, i would appreciate.
Many thanks for reading.
Have a nice day.

Listen I’m not like really good when it come to hacking or anything but I do know that in order to hack android you either need to A, be tricked somehow into downloading and installing some malicious apk or B, someone needs to have physical possession of your device for a short time. Anyone who knows more please correct me if I’m wrong. I think some of those apps for hacking android can survive a factory reset also. But your problem sounds different than just that. It won’t connect to a WiFi network? Try a different network is what I would think to do first.

Hi
I also dont think your device got hacked like @messymatthew already told either you need to install a malicious apk yourself or someone did it with physical access.
But your main problem atm is that you cant connect to your wifi at home which leads me to the question which android 8 rom you have installed right now ?
Or is it the last official oem 5.4 rom which is android 7. In this case its maybe a problem with the PMF function of your Router.
If thats not the case you have two options:
You install the factory recovery image you can find here :
Tablet Recovery images
For this you need to download the right image for your tablet (LTE, K1)
Then follow this instructions :
Instructions - Adb needed
Or you install a Custom Recovery like TWRP you find here :
TWRP - Custom Recovery - Adb and OEM Unlock needed
After this you can install a custom recovery like LineageOS.
Maybe you interested in my unofficial version of the last official 15.1 (android 8.1) which should fit your needs if you want use it as a normal Tablet with monthly security updates.
Scavenger87 - Unofficial LineageOS 15.1

Hello,
Sorry for late reply.
Many thanks to both of you.
EDIT : Forgot to tell you that you are right, my tablet works with Android 7 not 8.
I have tried to connect straight to my modem (so not runnig through my router) and i succeed.
So it seems you are right there is a problem with my new router ASUS GT-AX 11000.
I'm gonna try the solution you are suggesting to me and will keep you posted.

Hello,
@Scavenger87 Many thanks for the help you provide.
You were right, it was the PMF function settings that were blocking my tablet to join the network.
Now, everything is working smoothly
Wish you a very nice day.
