Wi-Fi Problem - Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)

I don't remember if these problems started with the new update I got but my Wi-Fi has been disconnecting a lot and, sometimes, it gets an exclamation mark. Is not my modem, I've done soft reset, removed battery and much more but there was one "fix" that revealed another problem abd, maybe, that's what's causing my Wi-Fi troubles.
So I go to the recovery screen to wipe the cache and a blue screen jumps reading "Installing System Update..." but after a while it changes to "No command". It's here where I press the combination for recovery again and this is how the recovery looked like

I wiped the cache, rebooted my phone and it works fine except for the Wi-Fi.

HELP! Constant Re-Boot!

Need a little help here...out of the blue today my phone started continuously re-booting itself. Only gets to the HTC screen and then re-boots. I have done multiple battery pulls with no results. I cannot boot into recovery either, tried that many times as well. My only option is a screen that I have not seen before that asks if I want to clear all data and then reset the device. Anyone have an ideas? Running Fresh 2.3.3, had no previous problems.
I had the same thing happen today. I had just flashed Fresh 2.3.3 to try to fix the GPS issue in the CM6 830 nightly, and my phone started rebooting every minute or so. I pulled the battery and immediately booted into recovery by holding down <home> and <end call>. I was able to get to recovery, where I flashed a different ROM I had on my SD card. I hope this helps.

Google apps not working, VIPERONE ROM

Hello everyone,
I'll explain my problem: a few days back, I unlocked bootloader, flashed CWM and flashed Viperone rom (2.7.0) Everything worked fine.
This morning, my google apps weren't working (gmail not syncing, can't login to youtube and can't watch videos (even though I get all the thumbnails) but internet works fine... When I open the play store, all I get is "No connection" and "Retry"
I tried clearing data but to no use
I then tried wiping cache and dalvik cache in recovery mode, when rebooting, my phone got stuck in a boot loop with "process system isn't responding"
I held power button and volume - for about 10 sec and it rebooted fine, gapps still aren't working though...
What can I do to resolve this issue ? (without losing data if possible)
Thank you

Click to expand...
Click to collapse
you could wait and see if it is a problem with google servers which it probably is other than that i would wipe and reflash
I solved my problem by following the instructions in this thread

Need assistance reinstalling twrp

For a while I've been using the nonsense rom (provided on this forum) and it's worked fine. Just the other day however I tried turning on my phone, it would get to the boot screen with the animation of the android bot peeing on the apple logo and it would just play that animation over and over until eventually the phone turns off. I figured I just had to restart, but it was the same issue. After trying to reinstall that same rom, I had the same problem. I then tried different roms and the same issue with those, they would get to their respective boot animations and play them until the phone turns off, never going past the boot screen. The one rom that sort of worked with the cayonogenmod 12.1 rom, but the issue with that is after the boot animation, it appears to be starting the set up for the phone, but prompts me to enter a password, which I have no idea what it is. Doing a bit more research, it seems that there may be a problem with twrp and it not formatting (term?) properly.
As of right now, I've done a factory reset on the phone several times to no avail. I just need help getting this phone to work. I've tried looking at a few places and using adb, but the device wasn't found and I didn't have time to look any further because I'm busy with a project I'm working on and with moving. Some places I've looked said to put the phone into usb debug mode, which I can't do since i can't get past any of the boot screens.
Edit / Solved:
I went into twrp and instead of choosing "wipe data" i went to "format data" and that seemed to fix the problem. Although I did have an issue with the nonsense rom, it got past the boot animation, but then gave an error "unfortunately the process com.android.systemui has stopped". I instead installed the raptor rom and it's working fine.

checking for updates screen stays on...

The phone was working fine, I did hard reset from the phone Setup menu, selected the WiFi network and the phone went into never ending (5-10 minutes) screen "Checking for updates... This may take a minute or two". There was no lock of any kind, no rooting, firmware flashing or anything - what could be wrong?
Went to boot reset menu wiped the cache and did one more hard reset - same thing.
just reboot the device. common issue.
Thanks!

P10 boot loop and "Getting package info failed"

Dearest forum,
I'm a little desperate:
My P10 randomly crashed yesterday evening without any obvious reason and got stuck in a boot loop for a few rounds. After 10 mins or so, it got its **** together and worked normally throughout today. Unfortunately, in the evening the same problem happened again. This time, I tried the "Download latest version and recovery" in the eRecovery menu but sadly, after installation it got stuck again during reboot (loop) and probably couldn't finish the recovery process completely.
So when I try to do the same thing again now over wifi, it displays the error message "Getting package info failed". The other two options "Emergency backup" (thankfully I used today to create some backups) and "Wipe data/factory reset" are greyed out and not selectable.
I haven't tried a factory reset yet, as I am hoping to still find a solution without losing my data. Is there a possibilty to do what eRecovery is supposed to do via fastboot? The HiSuite unfortunately just says, that my device is not supported for recovery...
Strange thing is, my phone is neither rooted nor unlocked. These times are way in the past for me, so I lost all my knowledge about all that stuff.
I first suspected the battery to have caused the initial problem, since that's the only thing I have changed over the years (Polarcell), but it didn't display any strange behaviour and all cable connections were in place, too. But now, after the unsuccessful recovery attempt, I suspect a soft brick?
Would appreciate any help!
Try to unlock it via potatoNv
(PotatoNV is free)
And then flash any firmware you like
Have a nice day
