Addison XTI635-01 camera doesn't work? - Moto Z Play Questions & Answers

Hi everyone
About 6 months ago i bought a used Unlocked Moto Z Play off of ebay - The description said the camera didn't work. Sure enough whenever i try to open the camera app, it crashes the app and says "Camera has stopped working". In fact the phone doesn't even think a camera is attached (no option to test in the "Device Help" app). I tried chatting with Motorolla support, but they wanted like $150 to fix the phone so i decided against that. I thought it must be a hardware issue and that's that, but i just accidentally booted into the boot loader mode and noticed something strange. it says my product is a "addison XTI365-01". After some googling, I believe that possibly means this phone was rooted and custom firmware was installed at some point? I really know nothing about rooting so perhaps i'm way off base, but could this cause the camera to stop working? Is there any steps I might be able to take to restore camera functionality?
The options I have for the bootloader are:
"Switch Tools Mode"
"Start"
"Restart Bootloader"
"Recovery Mode"
"Power Off"
"Factory Mode"
"Barcodes"
"BP tools"
"QCOM"
"Bootloader Logs"
I'm not sure if any of those options might help with determining if this phone is rooted or if custom firmware is installed?
Any help is hugely appreciated.

1635-01 is the verizon version of the phone. it cannot be unlocked so it hasen't been modified. don't know what happened to the camera - probably a mfr defect. You could always try taking it apart and replacing the camera but the mobo could be bad. At least the seller was honest and told you. Shouldn't'a bought it.

Would you happen to have a custom kernel? Which Sony Ericsson logo is it, the non-moving one or the animated one?
Now, you wouldn't have happened to install a CyanogenMod, Ice Cream Sandwich or Jelly Bean rom, would you? I know you don't remember which rom you installed, just trying to spark a memory. Anyway, if you did so, then all you need to do is flash a compatible kernel. You see, if the Sony Ericsson logo you are seeing is the non-moving one, then you have the stock kernel, the one that's incompatible with the aforementioned roms.
If you don't want to get involved with this kernel business, then I've provided a Flashtool guide, so you can at least get your phone to a working, albeit factory reset, state:
First, install Flashtool.
Go here and find what you think your stock firmware was, download it.
Place the .ftf file in your Flashtool/firmwares directory.
Open Flashtool (as administrator if necessary) and click on the lightning bolt in the Flashtool window. Highlight Flashmode and select OK. A new window shall pop-up.
Select your downloaded firmware. I should read "R800i" in the first box and "4.0.2.A.0.XX" (with the "XX" being the number of the version you downloaded) in the second, the contents of the third box varies, so disregard it. There are many options for what to keep/replace during flashing, but I'd recommend leaving them as they are. Select OK. The window will now close and a new window will pop-up shortly after.
This window will detail the proceeding steps: With your turned-off phone (make sure its battery is intact), hold the back key (the leftmost one) while inserting the usb from your computer to your phone, continue holding the key until the window closes, DO NOT REMOVE THE USB.
The Flashtool window will now begin streaming various lines detailing its progress, all you need to look for is the line detailing a successful flash which with then tell you to disconnect your phone, now you can remove the USB.
Go ahead and close the remaining Flashtool window, your phone should now be back to default, factory reset, everything except your phone's bootloader and SIM unlocked statuses, they should be how you left them before.
thanks!

Okay, having not used stock in a long time, I've reverted my rom and kernel! Upon doing so, I noticed little wrong. Though I do remember an annoying prompt when I opened the browser, it'd say "Please insert SIM card" and "downloading settings" would pop-up following it.
Aside from that, I can't recreate the problem you're having. Could you go into more detail?

Well... That's something I have never seen before...
Searched the Q&A and troubleshooting section, and I'd found a thread detailing such an error upon switching firmware. No offence but perhaps I didn't give you enough detail on which firmware to download, and for that I apologise.
Would you happen to know what branding your phone is, and post what it is and which firmware you installed (you can find said information in that third box I told you to ignore in Flashtool)? AT&T, Verizon, unbranded/no SIM/unlocked? I ask this as you may have installed incompatible firmware.
As an example, my phone was unbranded and came with no SIM, the pre-installed installed firmware (and the only one that I find to be fully compatible) was the R800i 4.0.2.A.0.42 UK Generic. In the context of stock roms, I find that it's best not to stray.
Anyway, you've probably already figured out what to do: find the intended firmware and flash it, using the instructions above. I'd recommend gathering some more outside help, changing the thread's title to reflect the current conundrum should be a good starting point.

Oh, sorry about that. I'd only ever experienced an APN problem when one of the roms I had installed had a broken settings app.

[Q] Samsung Galaxy Tab Kids SM-T2105 Problem

Hi there.
I am new in the forum. Thanks ind advance for any help you can provide me.
Here's the issue:
We just bought the new "Kids" Version. It came with 2 accounts, the normal mode and the kids mode. The kids mode was accessible through a "Kids mode" icon in the normal mode.
I really don't know what my wife did, but she erased the "kids mode" icon and that account is not accessible anymore. Still, I can search for the kids apps and they still show up.
I got two different error messages. An "error 210" and the "Unfortunately the Setup launcher has stopped" (or similar. I don't have the tab here with me)
I thought my only choice here was to download the firmware it came with it, which is T2105UEAMK3-XAR, and re-install it. But KIES won't let me install it, since it displays the "Your firmware is up to date" message. And Samsung doesn't have an official firmware download anywhere. I also talked to an online Samsung representative, who directed me to perform a hard reset. Still, back to factory settings, the "kids mode" icon didn't appear. So he told me to schedule a service. But my daughter won't get any happier if I send out her beloved toy for a week or two.
This is my first venture (or issue) with an Android device. I have found a seemingly endless numbers of video tutorials and the likes, but still, I don't want to mess up with it.
Any help would be greatly appreciated -specially by my daughter
Thank you.

Is there anything I can do?? Locked bootloader R800x, rooted.

Hello. I've rooted my Verizon Xperia Play, but I can't unlock my bootloader. I've checked the service menu, I don't have the ROOTING STATUS menu, and the Flashtool identifies BOOTLOADER STATUS:UNROOTABLE.
I've tried Sony's unlock site but my MEID contains letters whilst the website states it has to be numeric. I've used the S1tool with the TP method and S1tool appears to hang, with the green bar along the bottom freezing after the "usb connected" noise plays; but if I unplug the usb I get an error, so I know the application didn't crash. I don't know if I'm letting go of the contact, or even if I'm doing it correctly because almost all pictures of the TP method are gone. I also don't know how long the S1tool TP procedure should take, and I've (or I think) held the contact for 15 minutes without any prompt or change in the program.
I don't know what to do now, or does this simply imply a sealed fate? Is it just not possible for me to unlock my bootloader?
I really need to partition my storage and ram but apparently can't without an unlocked bootloader.
(wrote all this with on-screen keyboard, sorry about errors/confusion)
Any help is deeply and sincerely appreciated!!
Thanks Again,
From a Newbie
haha I didn't think anyone would be in the same boat as me, let alone within the same year
I've been scouring the web for probably a good 5 hours on this and I'm stuck right where you are. By some miracle, I was able to find all the files I need for CM9, the flash tools, Gapps, and etc.
I also was able to get it rooted, and in dt674's guide I'm stuck on step 15. Fastboot recognizes my device and all the files but when I try to send the recoveryPLAY.img it returns the "FAILED" error and tells me that it has to be rooted first... Even though it already is rooted... I would assume it would have to do something with the bootloader still being locked, and like you, the Sony website didn't accept my MEID code for not being entirely numerical... If I find anything else out though I'll keep in touch.
I'm in the same boat as you guys... Managed to get my R800X rooted by flashing to 2.3.3 then using the oneclick method, but I've got the same issue with the bootloader and the numerical MEID.
Honestly given the Xplay's age I think we're pretty much SOL and too late to the party when trying to look for support on this device. Most of the ROM links are dead, and the more supported/popular ones are for the GSM models, and the ones that still have their files hosted require an unlocked bootloader at that. Unless one of you guys has a magical solution for why our MEID's are messed up I'm stuck on 2.3.3 for now. At least I can still sideload mostly everything I need.
Yeah I'm pretty sure zzkoto is right lol. Just too damn old haha, so we're SOL.
I have reached out to the developer site support though, and I'm trying to get them to investigate the problem regardless. I've only gotten one email back in...a two month time period about? So we'll see what happens. Apparently they updated their site and fixed the problem... but it's still broke for me. Will post if I get any juicy details from them, or they email me about any fixes with the MEID errors on the site.
LADS, so they HAVE fixed their website, it's just at a new URL, and they haven't decommissioned the old one yet for some reason, which can be found in this very hyperlink.
And it works great, I got my code after inputting my MEID, shoved that into an ADB string and ka-blammo it's unlocked no problem.
Now I'm running LuPuS Kernal with CM9, but now I'm hitting a brick wall where the darn Wifi won't even bother to turn on (when it did with stock before) which I guess is a problem with R800x and the Play in general... Back to the drawing board lol.... Think I'm gonna scrap the CM9... Anyone Come across any good Kernal/Rom combos that make the Xperia Play a lean mean Emulation Machine? I'm feeling some classic PS1 MGS lately...
Alright here's one last update, just in case y'all have the same problem as me with Wifi.
I went back to stock 2.3.4 and my recovery Kernal, and Wifi worked again, so I decided to try something different. Installed DoomLords 2.3.3 Kernal v01 (the only download that worked on that page). Then after booting into recovery, I restored into Cola v6. After that I installed DoomLords wifi modules zip in CWM and boom wifi works again, and Play works completely as intended. Only hang up now is that the Android Market won't let me download anything because it's so old, but It's easy to get the apk's on my other phone and move and install them. Other than that it's incredible. Happy hacking y'all.
Great find on that bootloader fix mate, I'll have to look into that and getting some custom ROMs/kernals installed.
For the market not working, Google discontinued support for the old Android Marketplace services or something back in early 2017. But if you install the latest 2.3 compatible version of the Google Play Store, Google services should be back up and running with modern-ish apps.
Here's the link: https://www.apkmirror.com/apk/google-inc/google-play-store/google-play-store-6-2-02-release/
Yo I figured it was something like that haha but I was overthinking it way too much. Thanks for the link to the Market, now I'm gonna go ham and get ALLL the emulators lol. Retro games here I come!

Phone stuck in "Download mode" after official Pie OTA update!

Hey good people.
Yesterday i was excited to see the notification for Pie update come up, so i quickly installed it on the phone. It finished, then asked me to reboot, so i did. But for some reason, the phone couldn't reboot properly, and ended up getting stuck in download mode.
Tried to get out of it using every combination, nothing worked. Then i decided, well, lets reinstall the firmware on it. If i could find any! Majority of links are misleading, don't work, yandex disk links didnt let me download anything. Tried like 3 different versions of OST, none of them worked, not even the patched one, not to mention the lack of firmware in the first place.
The only step forward i could make is getting the phone to show up in device manager, because it hasnt even showed up before.
i've never even fiddled with the device's software or anything, everything was 100% stock and untouched.
i'm seriously disappointed in nokia, already contacted the reseller who yet has to reply (i don't have much hope for that either).
Any kinda help would be highly appreciated.

i honestly have no idea about the type, but i have screenshot

Don't you have the retail box? The type should be written on it. Also, do you have the ZEISS logo on the camera? If not, then you most likely have the TA-1054 variant, which is for the Chinese market.

it must be the Chinese then, because it doesn't have Zeiss or android one logo on it.
But actually, is that very significant?

Well, I cannot be 100% sure. But I would assume that if your phone was running a ported version of the global ROM and not the official Chinese firmware and it somehow got an OTA update then because of the differences in how the phone's memory is partitioned it would make sense that the device ends up being bricked after trying to flash something not ment to be flashed on it. :/ I hope this makes some sense to you. Also, if I am correct then it makes no sense to blame HMD for this because they have not done anything wrong. It is most likely the reseller who reflashed your TA-1054 with a ported version of the global ROM.

i've legit thought about that! the box itself has lots of chinese on it, so it might be the case. Either way, reseller responded and i'll probably just sent it back to them this week because apparently it's their fault.
strangely, my mi a1 didnt even let the OTA install when i had the bootloader unlocked, so it's weird to see a phone getting bricked like this. I actually felt guilty for letting the OTA install, even though i didn't do anything wrong here (exceptionally:laugh
Thanks for the suggestions m8!
I think You bought a crappy Chinese dummy Nokia 6.1 HMD is not in Finland hands anymore.
The hardware is different. And the software is Android one.
I am curious how your reseller solves the problem.
can anyone tell how can help to exit from download mode. i have tried by connecting charger and holding pwr button and vol up and after andriod logo came i released by pwr button and holding the vol up button. its not worked
later i connected to my pc and install adb driver and fastboot and then through cmd prompt i run adb bootloader but its not working then i check adb devices but there is nothing shows in attched devices and also i tried with fastboot reload then mobie restarts and came back to dowload mode. so out of these step can anyone have any suggestions to get back my mobile..thank you
ok so, i kinda neglected the thread but heres what happened:
i tried EDL mode with deep flash cable, didnt work. i tried installing all sorts of drivers on my PC from all sorts of sketchy sites, after a point i decided not to mess my PC or the phone up even more.
i contacted my reseller who "fixed" the phone by installing the pie update on it somehow, and it's functional now. i even told them the phone wasn't the european version but they didn't seem to care, and i didn't feel like playing with them anymore. but it's FAR from stable, buggy as hell, and LTE B20 doesn't work either (that might have a thing or 2 to do with the phone being chinese...)
thanks for all of u for helping, this particular phone was way more than enough reason for me not to buy a nokia again ))))

Trying to get a clean install on a crippled SM-T540 (Galaxy Tab Active Pro).

Edit 3: USIC, after further investigation, has confirmed the tablet was actually one lost in shipment and compensated for by insurance, the sale was legitimate (not a stolen device) and they unenrolled it from KNOX before I could ask if they would do so. So, overall a satisfactory outcome, even if the tech part of me wanted to find a way to defeat a technical challenge.
EDIT 2: The device may not be stolen after all, seller has given a plausible explanation. Withholding further judgement until more information comes in.
EDIT: I was originally thinking of 'USIC' as a subsystem of Android or KNOX. A user on Reddit suggested I reach out to the company USIC and see if the tablet was stolen from them. I did. It was. Will be getting the tablet back into their hands and pursuing a refund from the eBay seller. Will leave this post up in case anyone has a use for the technical rabbit hole I went down.
Backstory: Found a good deal on a new Galaxy Tab Active Pro from an IT liquidator company on eBay, it was listed as locked and price reduced because of that. I thought along the lines of 'hardware access is total access' and figured I would be able to wipe / reset it.
Device arrived today, the crippleware (MDM or administration software actually, but I'm feeling ornery at it) installed is Soti Mobicontrol. I can boot into the OS but a bunch of stuff is disabled. First I initiated a factory reset from Settings - it resets and during setup lists "This tablet is protected by Knox Cloud Service. To continue setup, connect to a Wi-Fi or mobile network." From there it states "Your admin can monitor and manage settings".... a bunch of stuff ending with "USIC will manage and monitor this device using the following app: MobiControl" with the only option being 'Accept & continue'.
Tried another factory reset through the boot menu (hold down vol down and power to reboot followed by hold down vol up) - same result.
Found and downloaded the same version firmware the tablet currently has: SM-T540_XAR_T540XXU2BTG5_fac.zip where XAR appears to be the US/Canada region code and T540XXU2BTG5 is the exact version of firmware the tablet currently has installed (verified by going to 'Software information' in settings).
Downloaded latest version of Odin (3.13), booted the tablet into the correct mode and flashed clean firmware (just the AP firmware) to the device. Went through first install sequence to no change in behavior, still installs Soti Mobicontrol as a device admin.
I've looked into maybe getting TWRP installed (so I can delete KNOX from TWRP file browser perhaps as demonstrated here:
) but as far as I can tell there isn't a build for this version of the tablet - closest I can get is for the SM-T547 XDA forum post on it here: https://forum.xda-developers.com/t/...alaxy-tab-active-pro-10-1-snapdragon.4284347/. Also not sure how I would get it installed since I can't enter dev options in the tablet (tapping on Build number, even in safe mode, results in a popup: Action not allowed This action is disabled by MobiControl. Contact your organization's administrator to learn more.)
I've found someone on YouTube (
) who removed the software just by intentionally entering a wrong password until a factory reset tripped - but I am already able to use the factory reset option and the software comes back. I'm thinking Soti Mobicontrol and the KNOX service are separate issues and in this person's example he was only dealing with Soti and not KNOX Enrollment.
Next I found this gentleman on Youtube:
who specifically mentions using the 'Nand erase' option in Odin along with flashing all files in the stock firmware to remove management software. Tried that, no luck. Same as each install I get the message 'Updating... Updating Knox Enrollment Service... X%' after being required to connect to wifi to continue setup with the 'Skip' option greyed out.
So, that's where I am right now with it, and I refuse to give up. Ideas?
@studentoflife don't know this device but might be a chance to flash the multiple part stock ROM you can get via Samfirm_reborn.

I am unfamiliar with Samfirm_reborn. What is this project? I can't seem to find much in the way of descriptive notes.
Edit: apologies, did some googling and now know what Samfirm_reborn is. I'm pretty sure I've already flashed all parts of the stock ROM - downloaded the T540XXU2BTG5 version firmware and flashed the BL, AP and CSC images. No CP image given this version of the device does not have a cellular modem.
Hm. I suddenly wonder what will happen if I reflash with the earliest version instead of the current one. I know I don't want to update it to the latest firmware in case that applies some security patch that can't be downgraded and locks out some workaround I haven't found yet, but downgrading... maybe.
I have a similar tablet with mobicontrol. I can't unlock OEM so all the methods of flashing new firmware I tried, failed. Have you had any luck since your last post?
