A2017GV1.2.0B02 Downgrade to Android 6 B10

Since I'm experiencing a lot of glitches with Android 7, I want to downgrade my phone to android 6 B10, hoping this will stop malfunctioning.
I downloaded the update B10 from the ZTE website and placed it on my sd card.
System Update finds the update, if I press update, will this downgrade my phone without bricking my device?
I know I will lose my internal memory but will I keep my EMEI info and sd card memory?

It won t harm your phone. It will just downgrade.

If fully stock, I don't think you'll be able to downgrade to MM. Lemme know if you are successful though!

You can downgrade without problems. I've done it a few times already (from 7.1.1 b01). I'm full stock, locked bl and unrooted.

I downgraded today, not without problems. It rebooted fine, than went back to the Axon screen, vibrating sometimes, so it was some sort of bootloop. I went into recovery mode and did a factory reset. After, it restarted and worked fine, I'm now back on android 6 with a factory reset, unfortunately, for me, problems from Nougat update still persist.

Which problems?

Anyone managed to do this downgrade successfully with stock rom not rooted? I dont have my country language to choose after latest nougat update.
Edit:
I managed to downgrade to b10 V1.0. Because of the Nougat update I was not able to update via external SD card although my card was 64GB.
I unzipped the file and placed it to root of internal SD. Did the normal update via settings and all went fine until it started to boot.
Somehow it asked password which I thought it was normal unlock code which i had placed previously, it wasn't.
Factory reset via recovery cleared that problem. All running normally now with marshmallow...
There is not much experts here to just to compare op3 Devs..

Nexus 6P insert other sim to continue update??

I have the next 6p and went through like 20 updates to get to 7.1.1 from 6.0 eating most of my data, but now.. I'm trying to go to the next security patch, but it says ’to install this update, please switch to your other SIM’ and no install button showed up.
What do I do?? I only have one sim please help.

I've never heard of this error, or a Next 6P. Is that your carrier? The 6P does not support dual SIMs. Try taking your SIM out and putting it back in? Borrow another SIM to finish the upgrade? Alternatively you could just follow the tutorial and go straight to the latest version of Android, skipping the interim steps and save yourself a lot of data and a big headache.

Stupid typo lol it's the Nexus from huawei, my carrier is total wireless and the 6P model.

Yeah only one sim came with it, and only one sim fits in the tray, and I got this error after the Oreo 8 update failed to install, then it went back to patching 7.1. That's when the error showed up

I'd rather not mess with root and risk void of warranty can I manually update without root?

Doesn't sound good. Well make sure your battery is fully charged, and try to find another SIM to get you past the error. You don't want to brick the phone while trying to update, that's for sure. If you do get the phone to boot, as a precaution you should enable Developer Settings and toggle on Allow OEM unlock and USB Debugging (if not done already).

I wouldn't abandon the current update at this point, but yes you can still manually update using an OTA newer than the version you are on using the stock Recovery, but I would strongly suggest toggling those two items in dev settings as soon as you can boot into the OS. There is a new FULL OTA out today for 8.0 (Build: OPR6.170623.019) so you could use that with your stock recovery.

This thread is solved now I guess. 8.0 finally finished and installed I guess I lost 4g at some point so it locked me out and thought I changed sim, while in 7.1 I did the developer options and removed and inverted sim again and rebooted and 8.0 went through.. never heard of this problem before or had it before till now.. but where I live I get 1 to 3 bars depending on where I am in the house, so I guess it caused problems.

Thanks for your posts guys. Kidna* just did all of the above all at once and something worked. Lol

PH-1 not seeing OTA updates

I can't seem to get the OTA. I've been on 7.1.1 this whole time (rooted with TWRP/Magisk) and have been waiting for the official 8.1 to be released.
I just flashed the full back-to-stock for 7.1.1 (using invisiblek's images), but after completing successfully, the OTA doesn't show up. I'm on T-Mobile, and I've confirmed that I no longer have root or TWRP recovery.
In fact, I noticed that there doesn't seem to be a recovery at all anymore (lying down droid). Is that normal? Is the stock recovery required for the OTA to be received? How do I get that back? TIA
Also, my bootloader is unlocked. Is that the issue? TIA.

Different carriers allow updates at different times.
Unlocked BL won't matter.
Try connecting to WiFi.

Easily overcome...

I'm with Sprint and my phone updated OTA yesterday.
My phone is unlocked and unrooted.

Thanks guys. OK, I'll wait a bit longer. I've already removed/reinstalled my t-mobile sim and connected via Wifi, but still no updates showing. Not getting any Nougat security patches either (I'm still on the Dec patch).

Anyone still having these issues? I'm stuck on 7.1.1 still and OTA is not showing 8.1. Tried removing and reinserting the sim & a factory, reset, but still no dice.
When I try to download the latest build on essential's webpage, I get this error:
AccessDeniedAccess denied.Anonymous caller does not have storage.objects.get access to essential-static/PH1-OTA-OPM1.180104.092.zip "Android 8.1 Oreo (OPM1.180104.092).

Solved... Telus/Koodo in Canada is just terrible with software updates. For some reason, just removing the SIM didn't do it and I had to insert a SIM card from a different carrier entirely. Worked immediately without even clearing data or restarting the phone!

Essential PH-1 downgrade

Hello yall!
So I am at a complete loss on how to fix the issues with my Essential device.
So I decided to post here in as much detail as I can and hopefully receive some answers.
I purchased my phone used from eBay about a month ago.
According to the listing it was factory unlocked.
I have AT&T prepaid.
Everything was running smoothly for about a week until I receive the notification for the Android Pie OTA.
(At this time my bootloader was not yet unlocked nor was I rooted).
Again everything was fine UNTIL I installed the security patch update.
As soon as I installed and rebooted my sim read as invalid.
I rebooted, tried to mess with network settings, factory reset, etc.
Turning to Google, I realize this is a common issue with the Sprint variant of this device (of course my luck would be for me to unknowingly purchase the Sprint variant not knowing there was any issues) and the pie update.
The main fix for this issue would be of course to downgrade back to Android 8.
Here's my issues...
I unlock my bootloader.
Install the Android 8 firmware from the official Essential site. (made sure to install the one for Sprint variant).
Flash.
The touch screen is not functional. At all.
Flash back to Android Pie and install TWRP
Flash Android 8 custom ROM.
Touch screen still not functional.
So I'm back on Android Pie and touch screen is working, but sim is still invalid.
How are other essential users successful in downgrading the software?
HELP.

Did you unlock your critical partitions along with the bootloader?

Do you think you could link that post for me? I can't seem to find it.
I also don't see any uicc option on my debice. (Not sure or that matters though)

If it's Sprint you need to wait 50 days before you can unlock it. CDMA phones are a pain in the ass to unlock, always buy International if possible!

This is required for the touch screen firmware to be flashed and OP needs to see this.

No OTA update since march 2019

Hello,
since march 2019 update, my phone Nokia 5 TA-1053, cannot "see" any further updates. It's June by now, and I was unable to update my phone by OTA with april and may 2019 updates.
What have I done, and didn't work:
1) clear cache partition from recovery mode
2) clear cache and data for Carrier Services app
3) clear cache and data for update service
4) trying all above without SIM card(s) inside the phone
Nothing is working. I'have bought this phone in November 2017 (in shop, without branding of any sort), and had no problems with system to this day. What can I do to update my phone, except wiping all system and data? @edit:
1) never rooted
2) never installed custom firmware
3) only official updates

My phone says that there is no new updates, and my system is up to date.

Fix for missing OTAs
1. Backup any photos etc you want to keep
2. Switch off phone.
3. Remove SIM.
4. Switch phone back on.
5. Factory restore/erase (without SIM).
6. When phone restarts, set location as India, connect to wifi (do not insert SIM yet), download all updates, OTAs should appear
7. Once all OTAs installed, reinsert SIM
This worked for me.

I have been seeing a similar issue of delayed OTA update availability. In my case it seems to help to reboot the device, then it sometimes finds the new update.
