[Q] Continuous reboot after 4.2.2 downgrade - Moto X Q&A

I tried following this guide to downgrade to 4.2.2 so that I could root my AT&T device.
I was able to adb and fastboot into the device. And I flashed the ATT CU update with fastboot.
After that the device constantly reboots after reaching the M logo screen,
I can boot into the bootloader, and I can send fastboot commands, but not any adb commands.
I also cannot load any of the options in the bootloader (Recovery, Factory, etc), they simply reboot the phone.
I don't care what version of Android I go to as long as it gives me a working phone. Please help!
Thanks.
Edit: I was able to recover my phone by flashing the 4.4 update. I would like to know where I went wrong, so that I could possibly still do the downgrade>root>upgrade path.

You know there's a way to unlock your bootloader for $43ish. Many success stories. Your phone playing life would improve greatly.

Helo! MotoX might be bricked.

Got this phone today with my new carrier.
Ran the pwnmymoto apk.
I made the mistake of downloading the latest update because it didn't seem like it actually rooted my phone(No root).
Spent a good amount of time trying all different aspects of things after encountering the reboot loop.
Flashed one of the Rogers(I'm with Fido) firmwares.
"no valid piv block in sp for system"
RSDlite won't detec the device to try again.
It's MotoX xt1058
What can I do? This whole firmware thing is complicated and I just want to restore to stock and never ever touch rooting with this phone again.

Does fastboot recognize your phone? First thing is forget slapmymoto , you can unlock your bootloader and flash twrp recovery. Second issue rsdlite will only flash your existing carrier firmware with a locked bootloader, flash other sbf firmware requires a unlocked boot loader. Third item is to stop the bootloops try clearing the cache, fastboot erase cache

Flashboot says USB Connected. I assume that's a yes. My computer does as well but only as "motorola phone" likely because I have no real stuff on the phone now. Oh and the computer makes the little "boop" noise of removing a device.
What are the next steps I have to take to fix things? Thanks for the quick response btw!

OK , put your phone into fastboot mode by holding down the power button and volume down button for 3 seconds and let go( must he done while phone is completely off) plug your phone in and open a fastboot screen ( I assume you have SDK) right click and hold shift while in SDK platform tools. Type fastboot erase cache

I installed the SDK and followed a guide to allow me to use fastboot and other platform tools, but when using "adb devices" I don't have any entries, and when I did the command you mentioned It sticks at "waiting for device."
Seems my phone isn't actually seen by the adb tools.
Follow what flashallthetime is suggesting.
btw, Rogers firmware is correct for your phone as there is no Fido specific firmware.

Getting somewhere...
The command prompt can seemingly now interface with my device. It runs commands but clearing the cache didn't fix the problem. I've ran the command though so if there is a next step...
EDIT: Okay it's charing and I can interface with it via cmd. I can now use RTDlite with it as it's battery is charging. Should I flash the other Rogers now? I have my unlock code for the bootloader if that's what I've got to do first.
Yes, reflash it with rsdlite, this is the version you want - Blur_Version.139.12.36.ghost_row.RCI.en.CA

It's all fixed up. Thank you everyone who contributed to this! Time to enjoy my phone.
Last thing would be flashing twrp. Does someone have a link to the proper files?
Now after your up and running, please don't accept any ota if you are rooted, we expect the Rogers kitkat ota soon. If you accept the kitkat ota while rooted and with a custom recovery you will end up in endless bootloops.

I certainly won't be accepting ota updates while rooted anymore. Like I said I didn't think that it had actually modified anything with my system, otherwise I wouldn't have accepted the ota update.
Where can I find the twrp for moto x 4.2.2? Do I flash through rtdlite as normal?

[Q] Wiped system by mistake, now i'm stuck at loading screen...

After flashing my xt1058 with a custom ROM (Eclipse), i realized my phone was having some issues.
So i tried to factory reset it. I accidentally wiped system (TWRP) and now i'm currently looking at the loading screen. It just stays there, white with the moto logo and nothing happens. I tried running 'Factory' in fastboot too, but nothing changed.
Can anyone help me to restore my 4.4.2?
Hope i haven't bricked my phone. Fastboot shows no errors.
You probably will need to rsdlite or fastboot back to stock 4.4.2 image.....IF its available yet for your phone.

RSD Lite did it for me. Download the 6.1.6 version along your retail rom and follow these steps here:

Note: If you can't get adb to boot to bootloader, just use the common method, down volume+power buttons.

or
In TWRP with sideloading activated: adb sideload rom.zip

[Q] 1092 TWRP on 5.0 bootloop, stuck in recovery [SOLVED]

Hi,
I was on 5.0, running stock recovery and rooted. Today, installed TWRP for 5.0 on my device. I tried to flash the droid command center widget on my phone usng twrp, and it failed. I also hit the fix permissions option. After that the phone does not boot up, simply flashes the unlocked bootloader sign and shows the moto boot animation for a second or two before shutting down.
I can boot into recovery, and the computer detects the phone. But adb doesn't detect the device. I have the 1092 5.0 OTA on my computer and saved it on the phone in an attempt to flash it thru TWRP, but that failed with the message shown in the img attached. I also tried flashing stock 4.4.4, but that gave an error "Updating partition details" failed.
Can someone help me get back into my phone? :crying: ADB doesn't seem to be detecting my phone, else I'd have tried to install a rom via fastboot.
I have multi-tool v4.1 installed, would I be able to flash a rom (stock unrooted and full wipe is perfectly fine too) via that considering adb does not detect my phone, but the computer does?
Well, that looks annoying.
I've found myself in similar situations when I've accidentally flashed something I shouldn't have. The good news is that if you can boot to recovery you can also probably boot to the bootloader and use fastboot.
Have you tried wiping everything and going back to stock? It's time consuming but at least you'll end up with a working phone.
I had to do this when I put the wrong recovery on a phone and it mangled partitions. Device wouldn't boot.
There are instructions for the moto x here

Because fastboot mode can start on your device even before Android loads (and can even run when Android isn't installed at all), fastboot mode is useful for updating the firmware quickly, without having to use a recovery mode.
Adb relies on android booting and usb debugging being enabled and the computer being authorized for debugging (L feature). Fastboot does not. Try booting into the bootloader and then run "fastboot devices" . Mine shows up. I suspect yours will too. If it doesn't then I'm out of my depth here.

Ah yes. For some reason, my fastboot file had gotten deleted from the folder and so the command didn't run. Everything went smooth once I noticed that. Had to downgrade to 4.4.4., but w/e. Thanks @oldcynic

[Q] [ q ] how to repair bricked (bootloader) moto x 1052

How to repair my bricked moto x xt 1052
Hi everybody...
Im new here.
I hope someone resolve it.
My moto x xt 1052 is bricked, means it is not powerup normally, no any screen displayed, no boot image, boot animation, but goes into fastboot mode sometimes on trying to go in it using hardware key pressing i.e. Power and volume down keys.
Here is the brief description what was happened......
My moto was on stock kitkat 4.4.4 for upgrading it to lollipop On 19th jan i was tried to flash cm12 over cm11 nightly as described in that thread , for that i was unlocked my bootloader, rooted it, flashed CWM touch recovery, flashed superSu zip file and flashed cm12 nightly over cm11 as described. But my device was stucked at boot logo. For resolving that issue i was flashed boot.img of prev nightly release(i.e. 1/15) through command promp using commands '' cd Downloads... cd fastboot... fastboot flash boot boot.img.
It flashesh image file successfully and device is booted successfully. I was used it till last 4days and regularly updated cm12 nightly via cmupdater.
But 4days back i was tried to remove warning message of device is ulocked bootloaded which was irritated me using same flash method and logo.bin files which was given in another thread by other members. But my BOOTLOADER IS DAMAGED and no any display was seen. I read many threads to repair it but no anyone give easy step by step guide. I was tried to repair it using motoflasher given in 1 thred. But as shown there no my device was not shown in device manager asQUSB****9** THERE is only adb interface in device manager. Also it says in motoflasher that no device was connected and output was incorrect COM port, which was refused to flash bootloader. Another thred of rescurrection of bootloader is not so easy and also download links are not useful,shows item was removed.
There is no another way, i thought bootloader is a kernel, so i was flashed zwiel kernel by same flashing method by cmd.
The problem remaims same, moto care told thay it will cost 6k for repairong which is too high. The descreltion is given in details for anyone who finds my mistakes and tell me angd give me suggestion. Xda is big deveopers forum, i know someone will help me.. So plzzz help me.
HOW CAN I REPAIR MY BOOTLOADER AND SAVE MY MOTO which will not useful then usable as a paperweight.
Have you tried to simply re flash your stock 4.4.4 firmware via fastboot since you say you can get into fastboot mode? Or rsd your 4.4.4 firmware. If you can get into fastboot mode I think you should be able to fastboot your stock 4.4.4 and be back up and running.
When in fastboot mode and phone plugged in and you type "fastboot devices" does it display a string of numbers for your device? If yes then you are good to go.
I am having a similar issue with a Sprint Moto X (1st Gen). I am able to get to fastboot mode and I have flashed the stock image for 4.4.4 using mfastboot (also re-did it using RSD lite as the boot.img gave errors using mfastboot) but the phone only still boots to a dark screen and vibrates roughly every 15 seconds.
Anyone have an idea on what else I can try? I've been scouring the boards and youtube, but haven't really come across anything on this type of issue.
Has been RDS flashing process totally completed without any errors?
The flash finishes with no errors when it goes to reboot the phone I end up at the same spot of a black screen that vibrates like its powering on then repeats every 15 seconds like its stick in a loop. Odd... I never get the smallest hint to a picture on the screen.

Your symptom I'm quoting is what I've seen when a bad logo.bin has been flashed to the phone.
Can you try another? Some are in http://forum.xda-developers.com/moto-x/themes-apps/collection-moto-boot-services-t2885395
Thanks for the suggestion.
I tried a dew different logos but the end result is still the same. Vibrates on power up, no display at all and repeats until I hold the volume down and count to like 10 when the next buzz cycle would happen so I can get into fastboot mode again. I should note that I can't see anything in this screen as well. I was starting to wonder if it was the screen that was the issue but the bootloop has me thinking otherwise.
I have another one with a bad screen and a replacement is on the way. I guess I can test it on this one as well but I'm sure the result will be the same.
I took a gamble on this one thinking I could bring i back to life, I figured the last owner just soft bricked it and flashing the latest stock would override what mess they did. I'll tinker around some more if there are some other options otherwise I can just flip it for parts i guess.
If I run the fastboot getvar all I get all the phone info so it gives me hope that something can be done, I just don't know what, it seems like I keep cycling through the same few processes hoping for a different result. I even tried the power + Volume down for two minutes thing that's supposed to bring up the "other" recovery menu, but with no display, i don't know what happening.
In a last ditch effort I did a tear down and connection check for all the parts so everything has been removed and firmly re-attached, certainly was nice to do that there instead of on the one I know will work once I replace the screen, but it sucks to still come up empty handed. Sorry for the long rant, it's just been a long few days of trying to find ways to bring this phone back to life.
Solved with downgrading
Sorry for bad english.
I had same issue.
But solved prev saturday hole day.
Using manual method instead of rsd.
Make sure u properly installed adb and mfastboot. For that open cmd and type adb. It shows command lines and then mfastboot. It also shows command lines then you are ready to go. If not, google it for how to install adb and also for mFastboot
Then download proper stock firmware for ur device. unzip it, u will get files of system, boot etc. Copy all this files and paste into mfastboot folder. Open command prompt in that folder by pressing shift and right key of mouse.
Then boot your moto into fastboot mode by pressing power and volume down key for a seconds. If u will not get in to fastboot mode try for many times unless u get it. I will get it after trying half hour.
Connect ur device to pc and run commans given in the following link. http://forum.xda-developers.com/moto-x/general/guide-moto-x-return-to-100-stock-using-t2446515
End with-- fastboot adb reboot. It will reboot ur device.
Enjoy.
Thanks for the steps, I feel like I have done that already save for the few end steps with the oem commands.
So I flashed the print image using that guide and it still vibrates every 15 seconds and no display. I grabbed the retail file from the motorola site (oddly enough they only have TMO on the file name for some reason) and I flash this and it doesn't vibrate every 15 seconds, but still no display... Maybe in the end the display is bad after all...
Like mentioned before, I already have one coming in black for the one that works for sure...so I guess I'll test it on this one as well. Just wish it was as easy to disconnect/connect as my Nokia Lumia was, that took less than 10 minutes!
So, in the end it was the display afterall. I ended up getting another replacement screen as I really did not feel like attaching it and detaching it (yeah, I'm lazy sometimes). After setting up the new screen I plugged it in to charger and what do you know, battery at 0% then the motorola bootloader unlock screen after 5 or so minutes.
Now I have two phones, lol. One screen came without the speaker on the to fro some reason... And I think I just messed up my main phone removing the frame to add in that piece so lint and such doesn't get into the phone so easily... Dang it!
Edit - Yep, now it has a nice rainbow line display across the bottom where the navigate soft button would be... Guess I have to get one more screen!

Go to the General Forum there's a dedicated thread with official roms for your particular model. Use download the ROM and flash through rsdlite. Always make a backup since it will wipe your internal storage clean.

If you installed 5.1 by using one of the TWRP backups, and did NOT flash the leaked OTA zip files, then you should have only touched /system and /boot partitions.. in that case, it would be safe to flash 4.4.4.

How to Re-Lock Bootloader?

I need to lock my bootloader to do an exchange at T-Mobile. I have 20R stock flashed, but it still says custom bootloader upon boot, how do I relock it safely?
I read that "fastboot oem lock" will work, but will brick it if I don't do it perfectly. Any advice on what to do?

2. Powered on the Phone (it took a few tried of pulling the battery and powering on)
3. Check the box for OEM Unlock in Dev. Option
4. Use Minimal ADB and Fastboot and type in

I'm terribly sorry if bumping is not ok.
Thought it wasn't worth making a new thread, since my post is about the one above.
Has anybody actually tried these steps above? (Since every other thread mentioning this says it's a one-way only thing..)
Does locking the bootloader means also loosing the custom recovery? (I'd expect that, but asking to be sure)
Does it return the phone to it's original state? (ie. before one unlocked the bootloader, or there are some differences?)
Does it also means I would be able to get official OTA updates and so on? (since with a custom recovery, that's not possible)
Thanks in advance.
Yes, it does work. I did it, worked perfectly. Yes it does return your device to it's original state. Just make sure the stock ROM is flashed and all should be well. I didn't try, but I see no reason why it wouldn't let you get OTA updates from T-Mobile. Let me know if you need help.

i think you loose the twrp phone doesnt show unlocked bootloader message did not check recovery but it must revert t stock one.. not sure about OTA since am not in tmobile network.
you dont need OTA. you can always download KDZ and flash it with LGUP.
and stay uptodate.

Thanks both for replying.
And no @raptorddd , I did not mean that.
Your post is the only mentioning that locking the bootloader is possible, while all the other similar threads have ony people saying otherwise / it's not possible. I guess a slightly doubt is legit to have, don't take it wrongly

are you sure you have h811.? i did not get that error ive tried this twice..
i remeber getting an security boot error on LG G2 i fix by flashing firmware .. so maybe KDZ could help..
if not am not sure then search for that error and find out how to fix.

ive done it .. it works. it will build dalvik once it reboots.
I was able to Lock the bootloader.
1. I connected the phone to my PC
2. Powered on the Phone (it took a few tried of pulling the battery and powering on)
3. Check the box for OEM Unlock in Dev. Option
4. Use Minimal ADB and Fastboot and type in

My H811 T-mobile phone needs service. It has original 20v software version. It is unlocked with TWRP and rooted. Can I use this method? Do I first have to downgrade software to some other version? Will this method also take out TWRP and root or do I still have to take them out before doing this? How? Please help.

no need to downgrade. to remove root and any trace if phone works. is to use KDZ then once it boots into system do the lock procedure. so it locks and the small white letter are removed. this way its like stock rom and recovery and the above commmands will make bootloader locked. and sent to repair. if bootloops try the freezing method.
Used on an LG Aristo that has Cyanogen and it worked

ive said ive done it. on the above instructions you dont beleive.??
i think you loose the twrp phone doesnt show unlocked bootloader message did not check recovery but it must revert t stock one.. not sure about OTA since am not in tmobile network.
you dont need OTA. you can always download KDZ and flash it with LGUP.
and stay uptodate.

This was the only one i found that didnt brick my phone and trust me ive bricked and unbricked this phone many times
When you use the fastboot command to lock back your bootloader, the phone doesn't revert automatically to the stock recovery and actually that is partly the reason why it bricks and other main reason is that changes made to bootloader to obtain root brick the phone. before you relock bootloader, if you have SuperSU (in-app menu option) or Magisk (uninstall zip file), use their respective methods to unroot the phone, then use twrp to flash .image file of stock recovery to recovery partition then use the fastboot command to lock the bootloader. Even then it may or may not work because if whatever method the phone uses to check the integrity of bootloader and/or recovery, such as md5, if it doesn't match, the phone will still brick. Since all your data on phone will be erased regardless as soon as you lock the bootloader, i personally just fastboot lock the bootloader, remove battery to power down, use the volume up and plug usb cable in from pc to put phone in download mode and just use LGUP (uppercut) if have kdz file already, which i do, i just let LG Bridge download the file, find it in programs folder and copy it to another location before LG Bridge deletes it --OR-- just use error recovery option in Software Update tab in LG Bridge as both LGUP and LG Bridge will detect the phone in download mode even if it is bricked.
By the way, I have used both methods above dozens of times without any issues, someone above who mentioned phone boot-looping because of locking the bootloader, it is boot-looping not because of hardware flaw which was widespread in LG G3 but a software issue (phone boots up, doesn't find the software configuration it is looking for and just restarts) and they are not the same issues, no need to freeze the phone, won't help.
the method works, but no OTA from T-Mobile. "verification problem".
When I try to "adb reboot bootloader" I get "security error".
If I try reboot recovery, TWRP is definitely not there.
Just want to update from20Q to 20X.
Any help would be appreciated.

The above points to you not giving permission possibly because either you missed the permission pop-up or selected option that didn't allow permission.
