Hi guys!
My brother purchased a Lenovo ThinkPad 1839XF1 for his son, which is running CyanogenMod, and was converted to Android 4.1.2, but the touchscreen does not work. I´ve tried to change it with the physical button, which actually displays on the screen that the touchscreen has been activated, but it actually does not work.
I would like to know if there is any stock rom that can resolve this problem, or if there is another way to set it up. I already reviewed the setting, and there is no other way to enable/disable the touchscreen. I also forgot to mention that the Camera does not work neither, and an error is displayed when trying to use it.
I was thinking about the chance to use the update on Lenovo to try to change it, or if there is any additional steps to try to recover it, as I´m not able to find anywhere the stock ROM.
Thanks in advanced.

Hi all. I flashed my stock 2.2 Milestone 2 to the MS2Ginger 3.0 about a month ago. Everything was working just fine. But after one to two weeks of use, some minor bugs started to trouble me. I am a Chinese user and I used Moto Smart HandWriting for Chinese input. Everytime i tap on a message box or anywhere else to input text, the screen goes blank. The machine is still responsive and I am still able to go back by pressing the back button. The only way i can input text now is to use other IMEs.
Another thing is that my physical keyboard started to get double bouncing which was initially alright after flashing the rom.
I figured that it is something related to the data/cache or something else because the phone was okay just after flashing the rom. So i booted into bootmenu and do the double wipe to clear all the setting on the phone. But when i rebooted into the system, everything was still there. Lock screen password, messages, account settings,etc. All of it was still there.
I then tried to flash the MS2Ginger again following walter's post in android development forum. Again, nothing was resetted.
I am very annoyed. Can anyone provide some advice? Thank you.
hi, i think this should fix your physical keyboard problem... worked for me

Hi everybody, first of all sorry for my english.
I bought an A500 on ebay a couple of weeks ago, OS was 3.2 factory, I was thinking about trying to gain root permissions and maybe install a custom rom but tablet seems to work ok and I decided to wait for official ICS release, which arrived yesterday.
After the upgrade I noticed, as others did, strange behavior of wifi connection (strong to leak) and I cannot add any widget on home screen (keeping tapped shows only choices for changing theme).
At this point I guess it would be wise to try and install a custom rom, but I’m not confident and I really need help from the start.
I understood I need root permissions, but to gain them I have to downgrade.
Can anybody please tell me what to do, using dumb-proof terms ?
Many many thanks in advance.
update: i tried to downgrade to android 3, i think i bricked it ...
after the update i get a red error "Boot verified failed" .....
Probably wont help much now that you've bricked it, but to add a widget you need to be in the app menu and switch to the widget tab. And you should try looking at the wifi settings for default action when sleeping. For some reason, mine changed to always disconnect from wifi after turning off.
many thanks for your answer
I do not know how but my display is screwed up!!
The phone display is QHD but the digitizer seems to be set to fullHD! why? how?
I've tried reinstalling a couple of original firmwares to no avail. The the problem is the same.
Now that the phone has been flashed stock original I now can not even finish the install process.
Does anybody have a clue how to fix this!?
Update:
I was able to get passed the initial setup and connected my logitech bluetooth keyboard to the phone. Now I can finnish the install and hopefully adjust the digitizer. But how? I still have no clue...
Thank you in advance for any help in this matter.
Hi,
I just changed from Stock ROM to latest lineage OS with TWRP. After installing some APPs, i figured out, when call comes in or out, display gets off (dark) and doesnt comes back easily. Now, touch doesnt response so I cant unlock with pattern. Booting to recovery doesnt give me touch response so I cant swipe for "allow changes".
How could i fix this? Maybe with flashing now Recovery or Kernel via Download Mode, but how to do? Thank u
I suggest flashing back to a completely stock ROM and start over.
The screen going black could be an indication of a problem with the proximity sensor. The touch could be a driver issue in the custom ROM.
Edit: Airdroid Mirror doesnt work to unlock pattern lock

Thank u,
but i forgot to tell u there is working USB Debugging with working Airdroid. Befor the issue Airdroid Mirror works great (control movements and clicks via Windows AirDroid Tool), but now with the issue i cant unlock pattern lock with airdroid. No response while moving Finger/Mouse but function keys like home work in Airdroid and also at touch.
Any idea how to fix this special thing? Is this an proximity sensor error?

Don't think the proximity sensor would be related to Android mirror.
Since you can't unlock the phone because the touch does not work, I would flash back to a stock ROM and check as many functions as possible. If the phone doesn't function properly on a stock ROM, it is unlikely to function properly on a custom ROM.

I just flashed one of some stock roms,this one: I9505XXUGNG2_I9505OXAGNG2_DBT frome the thread "go back to stock rom" and did wipe data factory reset. It installed some apps, but then no touch is responding.
I did opened phone, reconnected all cables but no luck. How to bring back touch is working?
Try one of the stock roms from samsung-firmware.org that is specifically for the carrier that originally issued the phone.
Could the problem be a loose connection?
Same problem here. Its an Samsung S4, german version.
I tried the jfvelte-version from https://twrp.me/samsung/samsunggalaxys4valueedition.html and it works great. Touch-screen works like a charm. Maybe this info will help other users.
Hey guys, I have some problems with my s4 and hoping you could fix these. I'll try my best to include details of what I did and any details that are missing that I will include
Started with me trying to install lineage ROM on my s4 when things started to grease up.
Ok the problem is the phone would not boot to the main OS but when it did I flashed the recovery(twrp)with odin which seemed to work for about a minute or two before powering off. Also I couldn't get to the recovery(twrp) even when pressing the correct combos I just flashed it again and again until it worked but wouldn't work sometimes. I went back to the stock ROM which didn't work either.
I know I am missing out on a few details but if any of you guys can help me that would be great.
partition error ?
