Porblem with a bad persist

I don't know how to put it but my dev at PixelExperiance failed to tell me that a clean install of PE will lose me my VoLTE.

Iam running Moto G5 Plus - xt1686. I used to run Nougat back in the day, switched to PE Oreo and then to PE Pie. Everything was fine, recently I edited the build.prop for the wifi display and forgot to set back permissions. The OS just stuck at logo. I then tried again and again and finally dirty flash a PE security patch update. Then I lose VoLTE, IMEI was fine, just no calls.

I then learnt from the PE community that clean flash is the way to go and then I tried that also but in vein. I then tried different versions of different ROMs and Stock ROMs and nothing works. I then learn about persist in this post. I know that I never touched it. But it looks like the problem, I tried many varients for it fix and none of them works.\

Now, I'am in a state where one of my SIM says that it works in "Enhanced VoLTE mode" but doesn't and the other SIM runs in 3G(don't) care much. I can't make calls on the 4G SIM, it just won't work. Previously both SIM slots worked in a mutually exclusive 4G mode, but now I got only one of them barely into 4G state.

Please I need your help in fixing my phone, I can't afford to make a trip to the service center and I pretty much know that the local repair shops doesn't know this ****(trust me Iam a CS student). I have a little experience in Android tinkering.

- Which version of STOCK rom are you on?

Used N, O versions of Aroma TWRP builds, none fixed it even with persist copy and firmware install

- Are you rooted, and running the commands under root privileges?

Nope

- Have you ever flashed someone else's, or another device's persist?

Nope

- What functionality are you missing and trying to restore (e.g. IMEI=0, VolTE, etc)?

Only VolTE, IMEI recovered after I manually broke it.

- Do you get any error messages when trying to execute the commands?

Nothing

Please oh please oh please help me. Thanks.

Please, there's no need to post in multiple forums and PM me, I do have a life of my own...

In any case, as IMEI loss is not your problem, generally if you install stock Oreo completely (including erasing EFS) and boot into it, then that's usually the way that most people have gotten back all of their Volte functionality. Don't restore your old EFS backup, let it generate a new one.

Give that a try, making sure to back up your EFS and persist beforehand. If it works, then it works for stock. Whether or not it will work for other ROMs is a bit of a lottery...
[Moto G5 Plus Guides, News, & Discussion] Jorge Lucas:
Does this work on other motorola devices too?
[Moto G5 Plus Guides, News, & Discussion] NZedPred:
Yes it works on the G5 series, some others as well. I see you posted on the G5S+ Forum, will have a look at your post there.

For G5

S

Plus ONLY:

backup everything

fastboot flash recovery twrp-sanders-r15.img (or twrp-sanders-r20.img)

boot into recovery

wipe all data and cache

reboot into recovery

flash SANDERS_OPS28.65-36_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip

flash SR3-SuperSU-v2.82-SR3-20170813133244.zip

reboot

install Termux from Google Play Store

follow instructions in the main post exactly

if it works again, don't forget to backup the good efs partition in TWRP

then you can install 9.0 roms with twrp-sanders-treble-new.img and root with Magisk-v18.0.zip

Can't guarantee it will help at all; good luck!

Dude you seriously saved my life you know that, i was stuck on a custom Oreo ROM and luckily i had backupped my stock ROM trough TWRP.

After the backup the ROM booted completely fine without issues, i even got full 4G but i couldn't relock my bootloader so i flashed a stock build over my stock build which wiped my efs and persist.

Luckily i haven't locked the bootloader yet so i was able to reflash TWRP again and flash the persist fix from this topic. Thanks to you i have a working stock 7.0 nougat rom again...

I can now finally lock my bootloader and install OTA Oreo... What a adventure...

I want to move back to stock. But i am afraid of loosing imei and/or volte.

I have flashed 50+ roms and enjoyed all the features and respect to all the devs but literally 3 things get almost annoying on all custom roms.

1. 60fps video recording gets broken on custom roms..

2. Slow motion very laggy or focus blurry on gcam and even on flashing moto cam on custom roms.

3. Eis on video recording also gets broken.

Is there any procedure to relock bootloader and flash stock rom and get all otas?

Any suggestions would be helpful.

My story of losing IMEI/4g/VoLTE

I too joined the club of '0' IMEI recently. I've switched to lineage os and when I tried to switch back to stock, I lost 4g/VoLTE/IMEI. I read all the posts in the forum and followed the most notorious one. Restored someone else's 'persist' and got my 4g back:victory:. I was happy with it and felt like achieved something, even though I just followed the wrong method. I used the stock with someone else's persist for more than two months. Everything was smooth until my fickled mind wants me to try Pie based ROM:silly:. Lost fingerprint sensor in the midway and forgot about the 4g problem and switched back to stock:rolleyes:. Boom!!! now it's gone for good. Tried restoring the same 'persist' which I flashed initially, but there is no use this time.

Felt ascetic with this and switched to the Samsung feature phone. Feeling happy and relieved from all disturbances:angel:.

But the feeling of spoiling a smartphone is haunting me. All devs, if you find any new methods to recover the IMEI back, I would be very thankful to you guys.

Hey i was using stock deodexed oreo rom on my g5plus and yesterday out of the blue (after using rom for 1 and a half months) i stopped getting signal.

I tried flashing stock nougat, stock oreo,stock oreo soak test1, deodexed oreo, los pie, omni pie but none of them are giving me my signal back.

I tried steps mentioned in op on stock nougat... didnt work, i tried restoring old persist and efs and that didnt work, i flashed soak1 firmware and that did no work either.

Also i have never flashed any1 elses persist and also have never lost imei, my imei is still showing

Do I have any hope or should i get a new phone?

Feeling like a caveman right now cant order food or book cabs or use whatsapp or call anyone since i cant get otps

Thanks in advance
[Moto G5 Plus Guides, News, & Discussion] NZedPred:
Sounds like it could be a hardware issue, especially if you've tried all the different stock ROMs you mention.
[Moto G5 Plus Guides, News, & Discussion] T3snake:
Never mind, nothing was wrong with my device. My sim stopped working out of the blue. Got new sim everythings fine now.

Thank you anyway

Hi there,

Nowadays, I tried to solve the IMEI 0 issue through GPST approach, but as you may guess, there are no enough information on how to enter the diag mode as com port number on Windows device manager.

By the way, I found the way through the link below:

https://xdaforums.com/showpost.php?p=54338876&postcount=3

Through the above information, I was able to back up my xqcn from QPST.

but I don't know how to find the exact address and offset of my converted IMEI. e.g. 08 xA should start. But, I was not able to find it.

If someone can let me know the exact position of normal qcn or xqcn file, I think that I can solve my 0 IMEI issue.

Who can share the address and offset information ?

Hello! I have a moto g5s plus(model XT1800) and the users that have folders rfs and rfs_shared are vendor_rfs and vendor_rfs_shared, respectively. I'm not sure if this method apply to my cellphone or if the users im seeing are correct. The thing is I have an IMEI and signal, but not LTE. Should I change ownership or try another thing??
[Moto G5 Plus Guides, News, & Discussion] NZedPred:
Are you sure you're not looking at the/vendor/persist folder?

What rom are you on? Custom or stock? If stock, Oreo or nougat?
[Moto G5 Plus Guides, News, & Discussion] tierniss:
I'm sure it's the persist folder. The /vendor/persist don't exist. I'm using a custom ROM.
[Moto G5 Plus Guides, News, & Discussion] NZedPred:
OK, so the ownership is always different on the custom roms. That's not necessarily a problem, however if you have problems with VoLTE or other connectivity I generally suggest that you go back to your full stock Oreo rom and ensure everything is working there. For whatever reason, some custom roms are a bit flaky with VoLTE, e.g. it will work the first boot, but not afterwards, etc.

Edit: Other thing is to try simple things like the network settings, in case something is not allowing LTE in your case. That happened to me on a custom rom - upgraded from one version to the next and the network setup changed.
[Moto G5 Plus Guides, News, & Discussion] tierniss:
Today I was making an EFS backup and noticed that persist seems to be screwed up, but EFS not. What do you think I should do?
[Moto G5 Plus Guides, News, & Discussion] NZedPred:
Do the backup, it's normal for persist to show as 0. It's just that it's really small.
[Moto G5 Plus Guides, News, & Discussion] tierniss:
Thanks pal, I'll switch between several ROMs looking for LTE and remind your words in case I go back to stock

Hello

I'm currently on Bootleggers ROM ( Pie ) which doesn't seem to have VoLTE

I bought JIO recently and had problems...

I wanted a fix which lead me to this forum

Could I get my VoLTE back by Flashing the stock by fastboot ( Nougat ) and updating it to Oreo ?

Use the TWRP flashable zips for Oreo, no need to go to nougat first.

[noob here]

i tried to flash a 9.0 rom and messed up everything. My IMEI was changed to 0. then i revert back stock 7.0 and still my IMEI was 0.

then came to this thread and flashed "potter-stock-persist-fix.zip". and then everything was fine. I got working IMEI.

but i am not getting any ota updates and got stuck in nougat. Can i flash any other rom now. wil i loose my IMEI again.

can anyone explain/redirect me to proper thread.

TIA :)
[Moto G5 Plus Guides, News, & Discussion] Wolfcity:
Flash an Oreo firmware and everything should be in place. Which one depends on the 7.0 version you were coming from before you flashed any custom ROM.

If it's related to your location you should receive OTA updates when your system is untampered, unrooted stock.

Do you think this procedure will work for a lost imei and wifi not turning on moto z3 play? I have a full twrp backup. Sorry if this isnt the place for my question
[Moto G5 Plus Guides, News, & Discussion] NZedPred:
No idea sorry. I don't know how similar or different your device is from the G5 series. What version of Android is on your phone? If it has Oreo or later, if the problem was anything like what we saw on the G5 series, then Oreo or later should fix itself.

You can always try and see what happens, but if you do it's at your own risk.

hello, friends. really nice guide for those who are worried about the so many problems with signal moto g users face. Im here asking for help. i have a moto g5 (cedric) i was working almost fine with oreo stock. i say almost because some times when i lost signal it didnt recover like any other phone woud, i had to reboot. now from almost a week ago i had lost signal and now i only have 4g. no 3G and no 2G, so no voice calls going out nor incoming ones. i ve done hard resets, flashing stock 7.0 and going back to stock 8.1 and nothing. on saw 3g for a little moment coming back to oreo. i also flashed carbon rom wich is android 9.0 to see if a custom rom helped but it didnt. i only have internet now and sms. and this is very frustrating. ive checked persist folder and everything is correct there. i have my imei right, this phone is like new but not being able to call is like not having a phone at all. also why i have to reboot to recover missing signal? is just a pain. this moto phones are really problematic when it comes to Signal management.

things to consider too: im currently on stock oreo, just rooted to be able to check persist folder. also my operator uses 900mhz band as 2g and 3g wich is an european frecuency not common in latin america. maybe that has something to do with problems im facing. the rom has cedric_latam_cust as the baseband. can anyone help me find one frome europe? im wondering if flashing one from there could help. the weird thing is that it was working before with that baseband.

so many people losing 4g, i could be glad if that was my case and had 2g and 3g only with full internet and calling capabilities.

im sorry i know it is a little bit too much information. but i really need the help

Hello.

The device 1685 (2sim). There was stock 7, then custom 8, then custom 9 (ArrowOS). Between them did a backup.

After 3 months on the custom Arrow, the network began to disappear on one of the sims. It helps to turn-off the sim in the settings. On the second sim (3G) everything is OK.

As I found out through trial, the problem occurs during the 4G-3G switching and back, the sim is turned off, which can be restarted programmatically, and again everything works, but I miss calls because of this.

The problem manifests itself in 2 cases:

- if some use 4G mobile Internet, the Internet stops working, after a couple of minutes the network disappears

- Mobile Internet is on, a call is received, talked, completed, 5-60 seconds, the network disappears.

If you turn off the Internet, use Wi-Fi, the network does not disappear.

I changed the sim to a new one, changed the sim in some places, restored efs and persist from the backup, today I have already downloaded stock 8, then another stock 7. The network still disappears.

UPD.

1. I took a sim from the same operator - the same story, the connection is lost. My sim in another device - everything is ok. By the way, lifecell Ukraine operator

2. If you turn off 4G, and forcibly use only 3G, then everything works (for about 30 minutes I tried to cause a problem using the methods described above)

In the settings of the mobile network is the default network type "all world". Put "GSM / WCDMA (auto mode)", the sim works, but the Internet is only 3G. The rest is still trying, but somewhere the calls do not work, somewhere the Internet.

Even rolling back to the stock does not help.

I still have one, the very first backup of the system, another 7th android, with which everything is exactly ok, but he does not want to recover, TWRP writes "you can not find a partition for copying oem", who will advise?

There is no such item when restoring.

boot

cache

data (excl. storage)

efs

logo

recovery

system

system image

If the sections alternate. Or, again, oem error, or - can not mount / system (Invalid argument)

I do not understand thoroughly. I guess I'm doing something wrong. Tell me how to correct.
[Moto G5 Plus Guides, News, & Discussion] Alex_Trane:
Continued. The problem of disabling the sim occurs only when switching 4G-3G (when the data transfer is on, a call arrived, the network switches to 3G in my country).

I read all the posts in this thread. I restored the stock 7, 8, personal backup persist, efs, I registered commands, applied patches, tried to change the network settings in the phone menu, nothing helps me. Fully, without exception, only 3G works. But I need 4G. Help me figure this out.

Problems With Signal 3/4G VoltE

Hello guys, recently I quit a custom rom PE 9.0 and go to stock 8.1 and unintentionally I deleted the Hlos partitions 1 and 2.

Then I flashed my own backup of EFS and Persist and my Imei came back, but I still have problems with a weak signal of 3g / 4G, it is falling all the time.

[Moto G5 Plus Guides, News, & Discussion] NZedPred:
You can use The TWRP flashable stock zips. Many people have reported success by going back to stock Oreo first. You just have to try it and hope it also works for you.
[Moto G5 Plus Guides, News, & Discussion] Wolfcity:
That's what I told you too. Clean flash latest Oreo fastboot firmware or try a TWRP flashable build.

I'll try that and tell you the result. Thanks.
[Moto G5 Plus Guides, News, & Discussion] aaron2812:
I followed every step that you mentioned. Firstly I flashed the stock Oreo ROM, which didn't solve my volte issue. Then I flashed stock nougat ROM and flashed the "persist fix.zip" file. Which also didn't solve my issue. Now I'm getting only 3G signal. I'm not getting 4G signal. What should I do now? I'm current on PE 9.0

TIA.?
[Moto G5 Plus Guides, News, & Discussion] NZedPred:
Check another sim card, or the sim card you have in another phone. Check there hasn't been a 4G issue for your provider. There's not much else that I can think of, and my guess would be that it's either a hardware issue or something outside of your control.
[Moto G5 Plus Guides, News, & Discussion] aaron2812:
Before doing this process I was getting 4G signal. But the only problem I had was my network signal was not as good as other phones.

When my imei was 0, a year back I suppose, before this thread was even created. I got my imei back by flashing a custom ROM and executing fastbood commands..

fastboot erase modemst1

fastboot erase modemst2

These codes brought back my 4g signal. But my cellular reception was way worse. For instance, another person having the same sim as mine should watch YouTube videos without any problem. But I'll be sitting next to that person waiting for a single WhatsApp message to send.

Someone please resolve my issue.☹️
[Moto G5 Plus Guides, News, & Discussion] Wolfcity:
So when your IMEI was 0 a year ago are you REALLY sure that you didn't flash another persons/devices persist file? It was a method that was often suggested that time as a proper solution.

Because when you flash the latest Oreo fastboot firmware for your location to your device it should definitely fix your problems and restore your IMEI and after using the fastboot erase modemst commands also your signal.

Think again.
[Moto G5 Plus Guides, News, & Discussion] aaron2812:
I don't remember flashing others persist file. The only thing I did was what I mentioned.
[Moto G5 Plus Guides, News, & Discussion] Wolfcity:
Ok, in this case clean flashing the latest Oreo fastboot firmware should solve your problems.
[Moto G5 Plus Guides, News, & Discussion] aaron2812:
I just noticed that I'm getting my 4G signal. But the network is not as good as other phones.

P.S. I didn't try other sim cards in my phone.

Hello, The issue with my phone is that VOLTE calling is not working. I've 4g connectivity as well as imei working perfectly fine. I'm on Arrow OS 9 and I've never flashed any persist on my device. Please advise what should i do so that VOLTE calling works on my potter device. Thanks in advance for any help.
[Moto G5 Plus Guides, News, & Discussion] Wolfcity:
If your IMEI is intact and 3g/4g connectivity is working also this should be a ROM related issue.

I recommend asking this in the Arrow thread, as far as I know there are sometimes external zips that can be flashed to fix bugs like this one.
[Moto G5 Plus Guides, News, & Discussion] paddamrit:
Thanks....I think i should try another ROM.
[Moto G5 Plus Guides, News, & Discussion] aaron2812:
I recently checked my cellular connectivity of my phone with another sim card and I got poor performance. I also checked my sim card by using it in another device and it worked perfectly fine with the other device. From this I'm pretty sure that the problem is definitely with my phone and not with the sim card. Please recommend any fixes. If you don't have any fixes I have to use Moto G3..☹️
[Moto G5 Plus Guides, News, & Discussion] Wolfcity:
Everything that can be done is written in this thread, I also recommended to flash the latest available signed fastboot firmware. Have you done this?
