Hi, I would like to know if there is a non-dangerous method to restore marshmellow on my Lenovo P2 (P2a42). The phone isn't rooted and the factory reset keeps Nougat as version.
Also, non related question, am I the only one who has problems acceding to recovery mode?
I searched on internet the keys to press to get it recovery, but my phone starts the os.
Thank you

To go into recovery its volume up+ volume down + power button until the recovery screen doesnt show up . why you planning on downgrading?
You should be able to flash the original factory image to the device.

I want to downgrade because I would like to use a more stable firmware while I wait Nougat to be fixed
I dont know if its true but i read on a russian forum that the modem could be corrupted if you downgrade , so be careful

I was looking for a non-dangerous way to downgrade, since i bought this phone just last week, but i won't take any risk and i will stay with Nougat, hoping they fix the issues fast

I used your methode. but mine phone is rooted.
But I don't have any probs
I just dont want to see anybody kill their phone , i'm quite happy on noigat at the minute . Only reason i unlocked the bootloader was to get off the crappy stock MM , and a few days after it unlocked they released Nougat .. typical lol

Oh come on... these guys @ 4pda were actually telling me that unlocking the bootloader will damage the phone...
btw I don't find the stock Nougat for P2 unstable, it's on par with MM.

Hi all, I'm a newbie with HTC devices. I've just bought an HOX and I want to root it to move a file to make the battery last longer, and then to disable soft touch lights that always stay ON ( even with screen off ). Which guide can I use to root it without unlocking the bootloader ? If there's not, can I unlock the bootloader in an unofficial way ? I don't want to lose the warranty. Thank u all.
You cannot.

Really ? WTF!!! It's normal that soft keys's lights are always ON ? Even when the screen is OFF ? Lights are OFF only when the phone is switched off...
How can I disable lights without root ? I read some tricks but didn't work for me
No, that's not normal.
I meant you cannot root it without going through htcdev process.
Before you unlock the phone, make sure it's fault free firstly. Get those soft lights fixed.

Dude, you can't root without unlocking the bootloader (-:
Thank u all !
the htc warranty center in my country is very disappointing .. I have heard of many phones brought in for service and back with other more serious defects. So I would avoid to bring it there. I read around on the forum a way to get the temporary root, which disappears after restarting the phone. Could you kindly link me the guide? I would like to do an experiment and see if I can turn off these damn led of soft touch buttons with root.

You just got the device.. Stop messing with it and return it to the store .. Exchange it before you do anymore damage. Simple.. Easy.... Requires no thought at all.

Well, I don't know that information, because I never use it. I only unlocked it by imei with a unlock code. I bought it used and in working conditions and then I sell it to a friend. After 3 days it began with the problem and we don't know how to solve.
At the begining I tought hardware problems with the power buttom... something like stun button, because I had a galaxy s2 with that problem, but it is not possible because I can put it in download mode and it do all the process with odin.

As far as I undestand yes. You need an specific LP version but Im still trying to find out this. The thing is that every root method is now outdated and my phone came from warranty with a newer version. I just dont know how to proceed.

Ok, according to http://forum.xda-developers.com/g4/general/psa-warning-try-to-downgrade-g4-t3197675 (bottom of first post) you can safely downgrade h811 from 20i to 10n
This whole situation could be clearer tbh

Things to consider:
Windows 10 may not work. I tried for over a day trying to backup my stock system.img using Windows 10 until some guy from another forum told me Windows 10 was probably having incompatibilities with the drivers.
Rooting. I had to make a VirtualBox virtual machine running the last version of Ubuntu (Took me 10 mins in total -downloading-setting the VM) but I also downloaded the files directly to Windows and copied them to Ubuntu. When I was rooting Ubuntu was missing files that were not compatible to copy & paste from Windows to the Ubuntu VM. So download the root_inject files directly to Ubuntu.

Yup that is the low effort root. That one is good when you have a stock room available, in your case V10N.
I went with the Ubuntu one because the version my carrier installed seems to work pretty good so I just needed root and had to do the 3 step rooting method with Ubuntu.
Enjoy!

well i just have root and xposed installed... .
i was told i idnt have balls to unlock bootloader... if he only knew
well i guess you dont know. as you told me i could not root and use xposed without bootloader unlocked.. guess i prove you wrong. as for grow balls dont even go there.. you dont know and once again i can prove you wrong... this isnt directed at you pakito someone else that siad those things.. he said bootloader can be relock and ive never said it couldnt do it.. all i wanted was warrranty. as even new 6xx are getting bootloops...
Whoever said it was not possible to root and xposed with locked bootloader is clearly living in the past. I had Xposed before I sent my phone to warranty, right now Im just trying to figure out why is not installing on my device.

Many times a phone becomes a brick because the tutorial "how to flash" was underestimated, people read them too fast, download any file, install everything randomly, everything very fast.... and later, oh... I ruined my phone!
Not saying that was your case, but it won't hurt you if you take a look again to the tutorials, and others fails and solutions.
Good luck!

Not sure if I should update because I'm still hoping for root some day. Should I give up and just download it?
G965U1OYM3ARH7 is the new update. I originally had G965U but was flashed to G965U1 when I learned it gets rid of carrier bloatware, I'm glad I did. I'm on bootloader 2 right now I'm guessing I probably should not update
?
Hey thanks for posting .. I have the same question but I have already updated so hope I'm not screwed for right now lol. I want to download and use that new experimental version of Android p for our device but am pretty sure I need to flash back the the U version (not u1) first. Hopefully I can do that still after the update. Please let me know if you find anything out or have any info on the this for me. Thank you so much I really appreciate it ?

I am in your exact position, Lol. But yes you need to flash back to U from U1 . I'm loving this Android P though. Yes I took the plung and upgraded my bootloader, I don't think root is coming anytime soon if ever. My front camera is working just fine with Android 10 and the dark mode that can't be turned off at the moment, I wouldn't turn it of anyways, Lol.
Help!
I am getting a security message popup on the p firmware. Any idea what size did wrong or how to fix this? Thank you !!
