Complicated problem, never came across in the whole lifetime of my android usage.

[whizinc]

TLR: Phone boots up and says. Launcher has stopped working, contacts has stopped working and etc.

Ok so i bought Moto G4 XT1625, yesterday. Was very happy with the device. It came with Android 6.0.1, i updated it to nougat 7.0.
But in android 6.0 and 7.0 both i noticed the phone giving random apps freezes and randomly even restarting on 7.0. The problem was minimal so i rebooted the phone 2,3 times and made it working. Then i received another update "NPJS25.93-14-4" on that update the phone got successful but bootlooped when booting for the first time on that update. I thoughts its ok so rebooted to bootloader and booted the phone from bootloader. the phone booted. after that another update came "NPJS25.93-14- (5 or 8) i dont remember properly" in this update the update failed during the installation. Keep in mind that i did not touch anything before this update. The phone was totally stock with stock recovery and everything. On this update the phone failed the update and i got constant bootloop no matter if i factory reset or erase cache it kept bootlooping, now i unlocked the bootloader and installed twrp and flashed a custom stock rom it crash on the boot. Again the random app has stopped working error came continously making the phone unusable. Then i flashed the stock rom correct firmware and everything it bootlooped again, then i rebooted numerous times the phone booted fine. Installed apps. This time did not get any app has stopped working error. Then rebooted the phone to install the sim card phone bootlooped again. Im 99% sure this is a hardware issue. Can somebody enlighten me? Whats going on in here? Thanks. I never faced this kind of problem ever in my life, i have bought more than 100 devices.

@whizinc
The Story is really frustrating especially when you bought it new :laugh:

So let's try to get your device working!
since you unlocked the bootloader you should clean flash the stock rom with fastboot https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138 and see what happens. Don't put sim cards in and disable wifi. Just flash, boot and play around to see if it works without reboot.

I used the OEMLock.bat script. So far the phone booted first time properly without any issue. Sim is working as well. Current its on setup wizard checking network. Lets hope its fixed permanently. I will play with the phone for 5,10 hours constantly and report back. Thanks alot man!

Good luck:good:

UPDATE

It did not get past the "Checking Network" thing and after pressing the power button screen went black but i could see nav bar and status bar only. The phone has faulty hardware. Im now sure. Going to get it back tomorrow from where i bought it. Lets hope i get a refund or replacement. I bought it from a local mobile mall.

Good luck:good:

this phone has faulty hardware. IT failed. Again random apps saying "keeps stop working" such as : snapchat has stopped working

Have you installed any third-party apps or restored them?

Have you installed any third-party apps or restored them?

nope, not a single app. Everything is clean and properly flashed.

Snapchat is pre-installed?

You did not get me brother. I was giving an example. Here is a real example:

"Contacts has stopped working"

".com android process keeps stopping"

these are the random errors.

It's irritating that you described that problem here before https://forum.xda-developers.com/mo...d-stock-jx-s-rom-series-t3658055/post73877878 now posting in a new thread. Does it mean you flashed the modified stock rom first and get the error and after this you flashed fastboot stock rom like described here? I don't get you.
@echo92 did you follow?

posted in a new thread because the problem did not belong to the rom's thread, im sorry did i do something wrong? No. I did not flash the stock custom rom before all of this. I never wanted to flash a custom rom. The thing is the phone failed an OTA update which let me to come to this decision. The phone failed ".5" update and after that it bootlooped. So i thought flashing twrp and flash a custom rom with a clean install would fix it but even the custom rom the " xxx app stopped working error" came continously.

After that i followed echo92's guide and flashed the whole stock rom through fastboot. Still same issue. Random apps crashing.

I think this is hardware issue. Because every idea has been fail till now.

What do u say?

edit: note: when the phone failed ".npj25.93-14-5" update it was completely stock and i did not even touch anything, i dont know why it failed on the first place?

Yep, I've been tracking the topic over both topics, gonna reply here to keep the other ROM thread clean too As I understand it:

Bought the device, had random issues with apps crashing on MM and Nougat.
Flashed TWRP and accidentally took the OTA, soft bricking in the process.
Flashed J-X's NPJS25.93-14-8 modified stock ROM, still app errors.
Reverted back to stock, still app errors, to the point where the device isn't useable and is now bootlooping...

However, @whizinc it's odd that you're experiencing these errors across flashes of the stock ROM and even a modified stock ROM and the data's been wiped each time...

Can you just confirm that with the NPJS25.93-14-4 (March 2017 fastboot ROM) that the stock ROM was flashed with these instructions as well, given that something odd's happening with your device...

fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash dsp adspso.bin
fastboot flash oem oem.img
fastboot flash system system.img_sparsechunk.0

fastboot erase cache
fastboot erase userdata
fastboot erase customize (optional: will erase any customizations if ordered through motomaker)
fastboot erase clogo (optional: will erase the custom boot logo if ordered through motomaker)
fastboot reboot

The difference is that these include re-flashing your GPT/bootloader (just in case) and also include the equivalent of a factory reset (so effectively a clean install of the stock, unmodified, ROM). I recall you've mentioned doing this, just want to ensure we have a clean slate to work with.

If you can, can you post the output of your flash commands, just want to see if the flash worked, hold fire on updating to NPJ25.93-14.5 for now (or if you want to try your luck, you can get the fastboot file from here - you need to flash it with the above instructions, as it's an upgrade: https://androidfilehost.com/?fid=673368273298984458 )

Else, it may be a hardware failure - when you bought the device, was it new or sold as used? Do you have a warranty with the shop you bought the device from? If you can, can you boot into bootloader, attach your device to your computer, and in the adb terminal, type 'fastboot getvar all' without the quotes, please? This should output a list of the basic details of your device, please post that here - you may wish to edit out your IMEI if you wish.

I have difficulty understanding why someone would void the warranty (by unlocking the bootloader) of a phone that is seemingly defective out if the box. Not a very good idea.

No no, You got the story wrong. Let me make it correct.

1: Bought the phone from a local mobile mall i have 3 days warranty left. (Phone was on Android 6.0 update)
2: Did not touch the phone. Just installed my daily apps. i.e: whatsapp,facebook and stuff.
3hone started doing odd things like auto touch while charging and apps saying "force stopped" error
4:Then i thought that this is Android 6.0 bug on Moto g4, so i should update it via OTA.
5: Updated to 7.0 same issues.
6:I saw another update did it as well 14-4 update. This update caused bootloop but i managed to make it through by booting from bootloader.
7: Then saw another update 14-5 and that update failed. (WHILE THE WHOLE PHONE WAS ON STOCK STATE) Why did the update fail? I didnt even touch the recovery or anything at that time.
8: Then i flashed the custom rom and the rest of the story goes on as u mentioned in the post.

And yes i cleaned flash the rom with the OEMlock.bat script that the guy above gave to me. It included all things such as boot,modem and all stuff. So it was def a clean install.

"fastboot oem lock begin
fastboot oem lock begin
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash dsp adspso.bin
fastboot flash oem oem.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash system system.img_sparsechunk.5
fastboot flash system system.img_sparsechunk.6
fastboot flash system system.img_sparsechunk.7
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot erase customize
fastboot erase clogo
fastboot oem lock
fastboot reboot"

This was the script i used to flash the fastboot rom which is 14-4.
Then again got force stop errors and the 14-5 update failed causing bootloop again.

I just have 2 hours to check the devices further or else im gonna return it today. Thanks

The phone was not in the official warranty from the start lol. I bought it used from a local mobile mall, they give 3 days checking warranty tho. I will try to get another handset. If i cant get it working.

Oh, you didn't mention that you have bought a used device! Bring it back to the shop and buy another/new one. Who knows what's wrong with that device or which history it has...

 

[echo92]

Apologies for getting the story mixed up, the information you provided in your corrected post and subsequently makes the situation worse though. Sounds like you bought a device exhibiting ghost touching or the beginnings of ghost touch and possibly was hard bricked/had the incorrect firmware flashed previously. As strongst mentioned, return that device. It sounds like it'll be more trouble than it's worth... especially for a used device.

 

[whizinc]

UPDATE

I returned the handset to the shop guy, he was skeptical at first but then he gave it to another guy who said that the phone would go in used market claim and then after that he'll either return me the money or give me a new G4 device. I'll have to wait till monday. It sucks. Anyways Thanks alot guys for the help i appreciate it alot.
