Hi. I am from Spain. I have just joined xda and I have read your issue with the Lenovo P8 8703X. I have had the same problem wondering why I could not pick up 4G or 3G network and eventually I got the answer from a russian forum. It is a forum for Lenovo but in russian. You will be able to fix the problem from there, because I just did.

Just google it and translate the forum in your language. Follow the steps of the forum member and your problem will be solved.

If you are still unsure then let me know, I will give you a more detailed explanation if needed.

Good luck.

Hi,
I'm another user having this issue with this tablet. I've tried to search on the Russian forum but due to is length, so far I was unable to find the solution.
Are you able to guide me? I think the post number should be enough .
Thanks in advance.

I have spent 20 minutes writing a proper reply to help out, .... anyways ... I will have to comply with the forum's rules.
As mentioned above, I will try through a message to you, it is a shame I cannot share it here in public so others can benefit.

Hi,
Just followed the steps and voilá... LTE working where he didn't work before! I will continue testing. I'm on LOS15 and happy with it.
Thanks to the user that initially posted the solutions on ru forum and thanks to user kingsemperor that guide me to it.

 

[kingsemperor]

Hi,
Glad to know that it worked. Glad to know that you are also proficient with flashing and understand the concepts of custom recovery and so on.
I am also happy that for this tablet there is an updated ROM, custom nonetheless, but still updated to Oreo.

Can you just check whether "Dolby" sound works for you?

Thanks.

 

[lcmg]

Hi,
I've instaled Dolby app throw the zip file, but is not working. App start but no sound on the demo option. I'm not root, not sure if that's the reason.

LTE issue confirm to be solved, I'm able to get network in all places I was unable before!! This is great!

Regards.

Dolby 8703x

Hi,
Dolby's demo does not have sound (the one who posted the zip file said so), otherwise Dolby sound should be working (with other apps, like music), it worked in mine, but then it stopped because I think that I changed the default music app.

I am root, so if you are not root, try to be root, because I think lineage has got the option to turn it on and off.

I will keep trying these days whether I can recover Dolby sound, the app is there but I can notice no sound change, the sound stays as it had no Dolby sound, but ar least it has good sound.

Fortunately 4G issue is solved thanks to that russian forum.

I will come back if I can solve this Dolby option.

 

[kingsemperor]

Solved this Dolby option by doing a "boot sign" from recovery.
Then it should work fine.

Solved for 3G/LTE problems in Mexico

Hi! I realized all the steps and worked well to solve the 3G/LTE connectivity in Mexico City, I have to update the Android Version to 8.1 and install an archive that repairs the modem of the tablet. (this tablet only works in 3G in Mexico, 4G/LTE is not available because of the bands of the tablet, something you can´t change).

Thanks to @kingsemperor to all of his help.

Greetings!

Hello !
I have just sent you the link via private message to the Russian forum, you can follow the instructions from that thread. Highwaystar is the user who gives you all the information.
Good luck ! :good:

Thank you

The link to the Russian forum

I think it is best now to show the link here as I have more than a few posts and I think I am allowed to do so .... that way there is no need to contact me through a private message for this.

If anyone has bought this tablet and has issues with 4G, 3G or even 2G then it can be solved by following the steps in this russian forum

Comments on this are appreciated.
Thanks !

By the way, whoever wants to upgrade to Android 9 (Pie), there is a new ROM that has come out. You are free to install either LineageOS or CrDroid (this latter one has more options for customization).

If you want to root it, use Magisk better here.

Always remember to do a boot sign and then the normal boot, if this is not done then your tablet might get stuck at the booting process.

See ya !
