Notice to all users;
In some countries of the world Google and providers no longer want ROUTed phones, because they cannot place commercial advertisements. They cut your data, or don't allow you
access your contacts or other things,
Commercial dictatorship, here we are!!!

Try to freeze or erase application AdAway only, or try unROOT if you don't use apps that require ROOT.

NitrogenOS-OREO 8.1


UnRAR and Copy NitrogenOS.novabackup on internal or SD card and install with Nova Setting.

Keep or delete the apps you like or not. Click on gray Apps not installed and install from Playstore

If you have ROM Marshmallow (6.x) or higher, use TWRP 3.X, if not, use TWRP 2.X to install this ROM and flash after TWRP 3X. Flash TWRP with Sp Flash Tool.

Ready to use as is, no need to add something.
Gapps installed, ROOTed Magisk.
Everything works perfectly. I'm not sure for USSD, you have to test. Some say it works well.
Start application "Performance Control" and set maximum speed 1560 instead 1690 for better stability
and lower battery consumption.
If SIM signal is weak, start "Power Menu" and click Soft reboot.
On first start, maybe all apps are not rooted; Start Magisk / superuser and check unchecked apps.

Network setting:
Go to System setting / Network and Internet / Mobile network / Advanced / Preferred network type / 4G auto.
LTE or 4G can run only on SIM 1 (Hardware)

Dolby setting:
First click choose function, second click, adjust volume by frequency.
Use Cameleophone to change IMEI if it is different from your usual IMEI, written on the phone's battery.

New ROM does not make a new phone, so do not dream.


This process works in all cases if the phone has the correct herdware.

Download Lenovo P70a Stock ROM and TWRP Rcovery:

Download SP Flash Tool:

Look here how to use Sp Flash Tool"

If Stock ROM installed start the phone and wait end of install (long).
Switch off the Phone and install TWRP Recovery .
Boot in TWRP Recovery and install the ROM from here, Needrom.
If ROM installed start the phone and wait end of install (long).
Switch off the Phone and install TWRP Recovery TWRP_3.2-2018.

When use SP Flash tool, start download, plug in USB after, phone switshed off.

In the extreme case, if you have problem with Sp Flash Tool, with the same scatter file-(Stock ROM), format the phone and repeat all.
In this cas you loos IMEI, but with Chamelephon you write it back.

Before asking questions, follow the instructions above. I tested everything and it works well every time.


※Please make a backup of your device before installing or updating ROM

      Elimination of major bugs, the ROM works well, which is not the case in any other version for this phone.

    Пробую прошивку несколько дней, не плохо. В отличии от Lineage oreo интернет не отваливается, звук не очень, но удалось не много поднять с помощью Viperfx. На RR-OREO-8.1 Звук очень тихий даже Viperfx не помогает. Продолжаю тестировать, пока нравится

      Lenovo p70 has very bad speaker and it is very difficult to get better sound.

      У Lenovo p70 очень плохой динамик и добиться лучшего звука очень сложно.

    Дело не в динамике, на прошивках что ниже Oreo добились не плохих результатов по звуку, а на восьмёрках у всех ромоделов проблемы, никак нормально поднять звук не могут.

      You may be right, I have not yet seen firmware 8 that would work better on Lenovo p70. Maybe it's done on purpose to change the phone.

      Возможно, вы правы, я еще не видел  прошивок 8, которые лучше работали бы на Lenovo p70. Может это сделано специально, чтобы поменять телефон.

      Where did you find Viperfx which works well on this firmware? For me Dolby works better.

      Где вы нашли Viperfx, который хорошо работает на этой прошивке? У меня Dolby лучше работает.

    На сайте 4PDA для 8 есть ViperFX&DolbyDijital Sound = [8.0-8.1][AE],с помощью этого удалось установить драйвер, а потом удалил это и поставил последнюю версию ViperFX с этой версией вместе с Dolby не плохо звук поднялся

    ViperFX&DolbyDijital Sound = [8.0-8.1][AE]
    Ставил через рекавири, потом просто удалил из системной папки, остался ваш Dolbi.С помощью этого удалось установить драйвер, у меня больше никак не получалось. Потом поставил последнюю версию ViperFX и он заработал так как драйвер уже установлен
