Remember that the erase modemst1/t2 commands are part of the flashing script for all the factory ROMS, and are run AFTER the modems are flashed. I think after doing that it takes the FSG stuff and restores it. Why it's necessary after a factory flash, dunno.

Two X4s Working Well on PPWS29.69-39-6-9; Alternate Solution to OTA Issues I now have both X4s working well on PPWS29.69-39-6-9. No connection issues, but I don’t know if they will accept OTAs (one did up to -9 after reflashing PPWS29.69-39-6-2, but it did suffer the -8 forced factory reset...

Now discontinued. I'm not sure what model is the successor but they made a lot of that style...I see some H730s on ebay, but new/old stock ones seem to be spendy. Look at the pictures then see what the current models are.

I've gone through numerous bluetooth headsets in recent years. Batteries were the main fail but I had sound problems on some, like raspiness and static. Been using Moto H3730s as it's the most comfortable I've found and has voice prompts. I can't wear the ones that stick into my ear. Maybe...

Factory firmware ROM A couple of XDA resources have mentioned PPW29.69-39-2 referring to it as the Pie "firmware version." This post https://forum.xda-developers.com/moto-x4/development/rom-moto-x4-t3890346 has a "firmware only" version of this ROM and a tool for flashing A and B slots...

All--according to a Reddit post, PPWS29.69-39-6-9 is pushing out to A1 Fi phones. https://www.reddit.com/r/MotoX4/comments/hak7vl/june_security_update/

Just something I did to be sure it was really wiped...since it didn't work earlier with one wipe.

So, my mystery of the day is how my phone could update and reboot 4 times with connectivity, plus several bootloop fails and a factory reset on the -8 update, then lose connectivity after the first post-update reboot. Obviously all is OK with the slots after 4 successful updates. Gotta be some...

I've never seen the clipboard bug you mention in Mint, using it since 2012. Just tried to reproduce it and no, copy/paste with mouse works great. ctrl+c & v work also. I use both. I ditched Ubuntu when they did that Unity thing. Possibly hardware related--mouse driver? I have mice...

Spoke too soon. After a shutdown and reboot connectivity is again buggered, just like before today's fiasco.

Back in the XP days bad/broken updates from M$ were almost the norm. They seem to have improved, but at its core it's still a klugey OS.

if this phone is truly working and stable I think I may decide to root it to prevent/control further updates. This -8 nuisance is a clusterf*#$&!

Just did a triple wipe data/cache/system in TWRP, then flashed -2 again. Phone took -4,-5,-6 with full connectivity and then bootlooped on 8. Ended up doing the factory reset. Nice update, Moto--did you guys recently hire a bunch of coders from Microsoft Update team?

My issues with flashing LOS are 1) I don't trust TWRP on this phone and 2) I read enough posts on the X4 LOS 17 thread to make me extra wary. I played with Randomblame's LOS build on XDA for the X Pure 2015 and it only got to be more or less usable after a year or more of builds. On my...

Reading further down in that post on A/B, there is sort of a thumbnail guide to flashing, but it is unclear whether it applies to all A/B devices or only Project Treble A/B's. So /data and most of the small firmware partitions are common and used by "both" systems. Apparently bootloader and...

If that's the case it would make sense you could 'fall back" to the stock rom in A...except, do the custom roms modify some/all of the small (and shared between slots) partitions?

Would love to read a guide on how to flash inactive slot. Haven't found one yet. Read on another thread somewhere that the switch active slot function in TWRP doesn't work. True AFAIK, I tried it. I've seen some flash scripts that begin "fastboot set active_b" and "fastboot flash modem_b...

No, if shut it down I have to first fastboot/erase t1/t2, then OK as long as it stays on. Thinking has something to do with NON_HLOS.bin. I'll try something next session. One thing, it is stuck on Slot A. The OTA would normally install Slot B. Something corrupted in that slot?

Connectivity I got the non-connective phone to get wifi and make calls again. I flashed -2 and then restored efs, fsg and dsp from an earlier (March) backup I found. Phone works but after reboot it goes back to that wifi cuts out every 20 seconds and no mobile state until I fastboot and do...

Regarding updates, the X4 Fi version released in October 2017 and supposedly receives 3 years of updates. So you may see some more updates. Apparently mine are never going to take updates without force feeding. BTW I saw some Reddit and other posts about connectivity problems and other issues...

Lenovo Rescue and Smart Assistant ROM updating I found the Windows software package Lenovo Rescue and Smart Assistant which has some updating flash tools. I used it on the no-connectivity phone, it found and downloaded the latest -8 May update (the full ROM, not the OTA). It automatically...

Connectivity, IMEI etc. Tried a bunch of fixes today, all fails. Restored fsg from backup when last working. Reflashed NON-HLOS.bin. Tried switching active slot from A to B (fastboot set_active b) and flashing -6 on it, gives a bootloop then reverts to slot A and boots to initial setup...

IMEI back after -6 flash and EFS restore but no connectivity Flashed -6 again and still no IMEI. Restored EFS from yesterday's TWRP backup (the third try on that) and IMEI is now back but no connectivity. Phone sees bluetooth devices though. Wifi won't connect and MAC address is basically...

Fastboot getvar imei displays the true IMEI of the phone. So it's still in there somewhere. Did not restore EFS from other phone. To be clear, with that phone the connectivity would fail each time it rebooted, but connectivity would work again (for one reboot) after erase modems t1 and erase...

Lost IMEI after restoring EFS I was trying to fix the problem with rebooting then losing mobile and wifi connectivity on my daily driver X4 running -6, and maybe getting it to take the -8 OTA. Before today it would lose the modems after each reboot until after I fastbooted and erased modems...

I see that update -8 is pushing out to Payton, neither of my phones will take it at this point including the one on -6 that took -4 and -5 earlier. KrisM22, do you remember what bits you restored besides EFS to get back to working stock? Besides efs1 & 2 I have Vendor, Vendor_image, Persist...

I downloaded Matlog and got it working, but I think I'll flash -2 and restore EFS again and see if it will update. Working on a project at home so I'll get to it in a few days. Need a rest from flashing phones, I think I have flashed these two at least 40 times.

Yeah, endlessly. Quits at 21%. Remember the title of this thread? The more things change, the more they stay the same.

If I'm not having connectivity problems after flashing -6 or -2 and EFS, but still not updating, would the Matlog be any use sussing that issue?

OK, thanks! What parta the planet you at? Lotta people here not wearing masks in town but I live out in the woods....I can walk for miles and see no one! Going to stores is very stressful.

How do I do that? Flashing -6 (and any subsequent) sounds like a plan. One thing, the EFS I restored was from -4, phone is on -5. Maybe version mismatch is blocking update?

Well, guess what. I restored EFS (only, no other partitions) from the 04/06 (-4) TWRP backup taken before I flashed -5 (that started my problems), and wifi and mobile are working. But software update continues to fail. I had tried restoring the entire TWRP backup earlier but it failed, I...

KrisM22, which (EFS, Persist etc.) partitions did you restore going back to stock after custom?

Secret codes etc. I'm on -5 now with wifi cutting out and no mobile. A number of those "secret codes" do nothing at all...some that relate to mobile signal do nothing if you don't have connectivity. I was looking at *2767*3855# The description is: The question is, exactly what firmware...

I'll try -2 again to see if I can even get spotty wifi back, then try some of these test codes and see what I can find. https://safetricks.org/android-secret-codes/ https://www.xda-developers.com/codes-hidden-android/ There's a thread on Lenovo about the wifi issue on Moto Z, but nothing about...

The same. I've flashed a number of Payton Fi builds and no luck getting connectivity. 29.69-26 (first Pie) gave no connectivity at all. It did that on the other phone as well but then flashing -2 got that one working again. I've been wiping system, data and cache in TWRP before flashing but...

Yes, and I even redid the erase t1/t2 again after 1st boot since that has fixed problems in the past. Remember, the phone was working fine on -4 until I reflashed -2 yesterday and I used only the .bat file you put together. Haven't modded anything else since. Later I may try switching slots and...

Wifi still cutting out and mobile not working after system wipe/data format/flash. Getvar now says both slots are bootable though. That is, "slot-unbootable:_a: no" "slot-unbootable:_b: no"

I just attempted to switch slots in TWRP and it gave an error, there is no bootloader on B. So without that I think the phone updating is not happening. The last flash of system_other.img with fastboot gave OK so I dunno what's wrong. If there's no bootloader to reboot to then I wouldn't be...

All makes sense, wiping system especially if you had a custom ROM. Going stock to stock, though, I'd think the factory script would do the job., and I don't see "erase system", apparently it dirty flashes the sparsechunks. I will reflash wiping system and see what I get. I posted the slot links...

Ah. Your 4/14 post didn't mention System specifically, just said "all 3". TWRP's standard wipe is Dalvik, ART cache and Data, so I assumed those 3 but I guess Dalvik and Art are the same. Thoughts on slot info/links?

Flash to -2 failed again Another fail. Flashed -2 on the stuck phone again with SIM installed and no mobile, wifi cuts out. Erased modems t1/t2 and that didn't fix. The other phone that is on -6 and has been working also started having wifi cutouts again (with the SIM removed), but erasing...

OK, I just found Format Data!

Advanced Wipe gives me these options: 1) Dalvik/Art Cache, 2) Data, 3) Internal Storage, 4) System, 5) Micro SD card. So wipe the first 2 and skip 3, 4 & 5?

Your back to stock mentions Format Data. I don't see where to do that in TWRP--do you just mean wipe? Wipe Data alone once, then Advanced Wipe Data, Dalvik & Cache? Do you recall what the was? Did you mean the Magisk patched boot image?

I'm blanking out on that--don't recall what it was. You haven't done anything in TWRP to switch active slots, is that correct? Just flashed to the last active one?

So here's some new strangeness. I wiped and flashed -2 on the other phone, the stuck-on-(-4) one, and I had the modems problem again with it. Tried erasing modems again, no go. I had put the SIM in it and mobile would connect for 3-5 seconds only, wifi same. then I put the SIM back in the...

I only did it with Magisk. It rooted fine, but we both know the aftermath of trying to get back to stock. In the next couple of days I'll try flashing -2 on my stuck on -4 phone that won't update, to see if I can get it back to normal. The one on -6 is doing fine.

"Crude" might describe TWRP backups that are faulty & don't restore....

Great! as for backups, isn't there a way to do full backups/restores via ADB?
