Hi What If I Boot from The Unbrick SDCARD and Downgrade The Bootloader Modem Etc With The -48 Firmware Can I , Its Possible Or Just Im Gonna brick the phone ? no one tried this ?

---------- Post added at 12:14 AM ---------- Previous post was at 12:11 AM ----------

Also, once modem is updated to 06.58.05R and even bootloaders are old, you can't go back to old modem, flashing old modem will make baseband unknown.

OK OK OK so lenovo must die jajajaja

hello [MENTION=7383447]MotoJunkie01[/MENTION] [MENTION=342404]ALI12[/MENTION] [MENTION=8371146]ozmage[/MENTION] this firmware is the solution for the radio deactivated?
[Moto E4 Guides, News, & Discussion] ALI12:
Sorry, I do not have phone right now... But do I have Moto G5 Plus, which I was doing some modification on persist because of same Radio off issue.

Baseband version was: M8953_37.46.07.01R POTTER_NA_CUST (Yes, R and but Radio was off).

I changed ownership of /persist/rfs and /persist/hlos_rfs, I read about this somewhere in a section of Moto G5 Plus.

After changing ownership of these two folder and it's files inside persist. I reboot my phone and saw baseband:

It was changed to M8953_37.46.07.01e POTTER_NA_CUST (Yes, e in small latter, still radio off, but this gives us some hope) :)...

command I used for changing ownership on twrp;

adb shell chown -R rfs:rfs /persist/rfs
adb shell chown -R rfs:rfs_shared /persist/hlos_rfs
adb shell sync
adb reboot

[MENTION=7383447]MotoJunkie01[/MENTION] can you paste here your phone's persist details? adb shell ls -l /persist

Then we can compare it with other phones that are with Radio off.

[MENTION=9350973]All[/MENTION] make a backup of persist.img prior to modification :)
[Moto E4 Guides, News, & Discussion] MotoJunkie01:
I'm pretty sure I posted a /persist image several posts back. I'm running a soak test ROM config on mine at the moment, so my current persist details won't help much. But I will search for the backup I made around a week ago.

[Moto E4 Guides, News, & Discussion] carlosvinuezap:
[MENTION=8371146]ozmage[/MENTION] with that you could turn on the radio? Can you explain how to do it?
[Moto E4 Guides, News, & Discussion] MotoJunkie01:
The /aboot partition restricts fastboot flashing of /persist. But you can write a script in Edify to flash the /persist partition with a TWRP installer. Sorry I'm catching the tail end of things. Did you all get the radio back on with Lineage? Sorry for jumping in on the tail end like that.
[Moto E4 Guides, News, & Discussion] ozmage:
No
[Moto E4 Guides, News, & Discussion] MotoJunkie01:
If you don't mind [MENTION=8371146]ozmage[/MENTION], please put me up to date a little on the progress. I've been busy as hell at work and I tried to read past posts, but if you could summarize on things, it would be great. Also, do you need me to write a TWRP installer to write to the /persist partition? Thanks friend.
[Moto E4 Guides, News, & Discussion] ozmage:
well the summary its that if you mount persist and change the permissions of the files on /persist the baseband changes from 05R to

05E and gets off the radio on stock and need to DD the backup persist img to get radio on back on stock , even on the bootloader mode the baseband changes 05R to 05E but dont make any difference and lineageos cant have radio on , its seems like lineagos dont have permissions to read the persist files and modem files i dont know im out of ideas .
[Moto E4 Guides, News, & Discussion] ozmage:
i installed resurrection remix on the first boot sim card not detected on boot 2 after erasing modemst1 and 2 imei 0 and radio off and the baseband ends on 05u weird ja but nothing works customs roms are off the table now for good until [MENTION=6485916]squid2[/MENTION] check it out what happen on lineageos after this ota

[Moto E4 Guides, News, & Discussion] ozmage:
on my phone the radio is always on , in stock , but not on on lineageos or RR crDroid nothing none of the custom roms works for me now after the ota my radio is off but on stock is ok i dont have to do anything to activate it , i just installed the ota at the begin of august like everybody but i was using stock until the 17 of this month when [MENTION=6485916]squid2[/MENTION] give us the new build of lineageos and i tried to install it and use it and i discovered that my radio was off and there is no way around to turn it on , i dont have a clue. but in stock everything is ok.
[Moto E4 Guides, News, & Discussion] resarfekim:
Hi, been looking at the last few pages and I'm confused.

Is it safe to run the restore procedure on my Sprint XT1766, NCQ26.69-56 ? Or is there a risk of modem not working or something?

Thanks!
[Moto E4 Guides, News, & Discussion] ozmage:
if you have NCQ26.69-56 and everything works for you why bother , you can restore but nobody would know if you win the lottery of radio off for some people the ota went just fine for others they dont have radio anymore and for me the radio is on on stock but not in custom roms .
[Moto E4 Guides, News, & Discussion] resarfekim:
I need to be completely stock with all traces of root/magisk removed.

So the risk is the radio not working after the restore, or after the OTA?

(edit - phone was originally rooted via KyleBryant's method)
[Moto E4 Guides, News, & Discussion] ozmage:

Not after. Before, you would never have had a bootloop. You flashed a clean boot.img and wiped data, so you basically uninstalled it the hard way. You just had to flash the uninstaller and flash 17.1 when you had the bootloop, would have fixed it without wiping data.

Moto E4 / E4 Plus Sprint No Service / Radio off FIX

1. Boot loader unlock (through official Motorola boot loader unlock)

2. Flash twrp / any custom recovery via (fastboot flash recovery recovery.img)

3. Boot to recovery mode, Go to "Mounts" and put a check on "Persist"

4. Open command prompt and copy/paste this command: adb shell chmod 0700 /persist/rfs/msm/mpss/datablock/id_00

5. Reboot phone and insert SIM card (if phone show Invalid SIM card, than you'll have to unlock/re-unlock it via GC Pro or SigmaBox)

6. -------------------> There is no step 6 :)

This will fix Radio off / No Service problem. Baseband will change to : M8920_15000.280.06.58.05R (Yes, R from E)

[Moto E4 Guides, News, & Discussion] MotoJunkie01:
Update: Effective 9/12/2018, Motorola Mobility has fixed stock radio broken for those members who were affected by the last OTA update. This is a server-end fix.

For Boost Mobile/Virgin Mobile/Sprint xt1766 owners who are running the stock Android 7.1.1 OS (Build No. NCQS26.69-64-8), and your device is stuck on the "searching for service," "No SIM" or "Invalid SIM" errors due to installing the most recent OTA update, or if your device is randomly dropping the cell signal, you'll first need to connect your device to WiFi. Go to Settings>System Update and select first Update PRL. When the PRL has been updated, reboot your device and again ensure a good WiFi connection. Go to Settings>System Update and select Update Profile. Once the client initiated profile is updated, open your stock dialer and enter ##72786#. Select "YES" from the SCRTN menu. Upon reboot your device should regain full cell radio and RIL functionality.

Note: it is not confirmed whether this fix resolves custom ROM radio functionality (e.g. LineageOS). This fix is confirmed to resolve the cell radio bug brought on to some users by the latest OTA on the current stock build.
[Moto E4 Guides, News, & Discussion] Rire:
"No PRL update available." Then again, I don't have a Sprint/Boost/Virgin SIM card. I still think this is a matter that needs to be resolved with LineageOS itself in regards to the RIL binaries needing updating as Squid2 mentioned. Just need to be patient I guess..

Edit: by the way, where did you get this info from, [MENTION=7383447]MotoJunkie01[/MENTION]? I tried looking for it but couldn't find it and am interested in reading about it.

This is a completely informal server-side fix, versus an actual, typical patch rolled out by the OEM. Motorola Mobility's certified service centers have received notice of this fix and, as far as I've seen, it has worked to resolve the stock radio issues incurred by some customers due to the latest OTA.
[Moto E4 Guides, News, & Discussion] MotoJunkie01:
I got the info at Motorola Mobility, which is my place of employment. On the issues incurred by users of LineageOS, who have experienced radio issues after installing the latest OTA & updated baseband, you are correct -- that issue will need to be addressed by a Lineage maintainer/builder. This informal server-end fix addresses only stock related radio problems. As I stated in my post, this fix is for users of the stock Android 7.1.1 OS only.

Ok. This is why you are seeing "No PRL Update Available." The PRL is updated client-side only on CDMA providers, such as Sprint, Boost Mobile, Virgin Mobile, Verizon, etc. Do you have the original Sprint SIM (UICC) card that came with your device?
[Moto E4 Guides, News, & Discussion] carlosvinuezap:
my phone did not bring any sim, as I told you to buy it released just 3 months ago
[Moto E4 Guides, News, & Discussion] MotoJunkie01:
I understand. This fix is only confirmed to resolve radio issues incurred on the stock OS for CDMA providers. Yours is a bit of a different situation, since you are using a Sprint compatible device on an international global provider. In order to try this fix, your device will need a Sprint SIM (UICC) installed. However, I understand your dilemma -- that your device didn't come with such a SIM. I would recommend that you contact XDA member [MENTION=8371146]ozmage[/MENTION], who seems quite knowledgeable regarding international providers on the xt1766. The info I have is useful only for xt1766 owners using Sprint, Virgin or Boost. I wish I could provide info favorable to your situation, but I regret to say I cannot.

[Moto E4 Guides, News, & Discussion] MotoJunkie01:
Interesting. So the server-end fix appears to be for Sprint based providers only in the U.S.

My colleague on the tech support dept just confirmed that: this fix is for Sprint, Virgin Mobile & Boost Mobile customers who incurred either a broken radio or radio stability issues after installing the most recent OTA update, and who are running a full stock configuration. So, based on this info, the PRL & Profile Update will only commence if you are a subscriber of Sprint or one of its MNVOs/subsidiaries.
