[Q] No service or just for a seconds :( - Windows Phone 7 Q&A, Help & Troubleshooting

Hey guys Ima need your help here:
Yesterday I was updating my Samsung Omnia 7, it has Mango installed but SFR-FR made a new OEM update available with improved firmware and bootloader. So I changed my carrier from 000-88 to SFR-FR, and started updating. From here everything went wrong: error codes floating around, workarounds wouldn't work either, so I thought: let's take a fresh start.
I flashed a UK retail rom (pre-NoDo or something), updated my device to Mango, did the same as I did above and now I was able to install the update successfully. But since everything went wrong, I am stuck with one problem: I have no service, or just service for a few seconds.
With my SIM card is nothing wrong, tried it out in other devices. So I guess it has to do with those updates: maybe one screwed up my firmware a bit? I have no clue. It probably doesn't have anything to do with the hardware, I didn't drop the phone or anything else.
I hope you guys have any idea to see what causes this problem, maybe I can do some tests from the Diagnosis app? Maybe there is a registery value that I need to check? Help is really appreciated

[Q] Update Mango fails every time

Today Zune prompted that the update is available so I started the update. It fails every time I try to update my phone :-(
I am already om 7720 but still Zune (and my Phone) pop up the update message.
I even did a full reset of my phone but still the update fails.
At step 5 it stays on 0% and the phone restarts.
Then step 6 and 7 (installing updates) ... again the reboot ..
Message on the phone:
Update Unsuccesfull
Unfortunately , we weren't able to update your phone. Refer to the Zune software or Mac Connector on your computer to find out what happened. Or if your're already closed this software, go to windowsphone.com for guidance.
See attached pictures.
Error code which I get is: 8018001E.
Need Help!
If you already did a full reset you can as well roll back to NoDo from your backup and try from an offically support version (7392).
How do I roll back?

Friend, if you have to ask this question, then I'm wondering if you truly knew what you were doing.

Ok, I used to get this error when I tried to update my firmware by changing my carrier code using Samsung Registry editor. As it turns out, Samsung firmwares are kinda locked to carriers. I tried Tmobile, Orange but the firmware would not install, getting the same error code as you did.
I had to wait for Samsung to release the firmware for my carrier.
Did you do anything to your LG phone? Like changing carrier code? If you did, you'll have to change it back.
Seems to be pretty common problem for LG E900: answers .microsoft .com/en-us/winphone/forum/wp7-sync/lg-e900-update-error-code-8018001e/1ec8d54d-0ee8-4db6-ab62-4ca26b3fbbe7?page=1&tm=1317157055038

I'm experiencing it too... ;/
Ok, I will chech the link later.
Thanks!
Hmmm
I think I figured out what is going on. Apparently Mango needs the latest firmware from LG to be installed on the phone. This was given to branded phones but not to unlocked/unbranded phones like mine, a few months back. With the firmware update the LG Optimus 7 will jump from:
Firmware Rev 1.0.7.10
Hardware Rev 1.0.0.0
Radio Software 1.0.7.10
Radio Hardware 0.3.5.0
Bootloader Ver 1.5.0.0
Chip SOC 0.30.2.0
to:
Firmware Rev 1.0.10.10
Hardware Rev 1.0.0.0
Radio Software 1.0.10.10
Radio Hardware 0.3.5.0
Bootloader Ver 1.5.1.0
Chip SOC 0.30.2.0
People who successfully updated their LG E900 to Mango already had that phone, from the little research I have been doing in the past few hours. So all we need is the firmware update from LG to be installed and I am hoping that this will allow us to go ahead and install Mango.

[SOLVED] Omnia 7 Update fail

Well... I have a strange issue... but on the other hand I feel I´m not alone. However it´s kind of messy trying to get a full picture from XDA how to get around my problem.
I have a 3-branded Omnia 7 with the following info:
OS 7.10.7720.68
Firmware 2424.11.9.1
Hardware 3.15.0.4
Radio Software 24.24.11.9.1
Radio Hardware 0.0.0.800
Bootloader 5.9.0.6
Chip SOC 0.36.2.0
My issue... well Zune keeps telling me Update 7740.16 is available (iI guess the Tango will come after that update, right?). I let Zune update but it comes back as a failure "error 80180048". Ok, so I tried to update using this guide http://forum.xda-developers.com/showthread.php?t=1306415
I got all files downloaded (lang files for each update... ) and it started ok... but after installation it came back with the same error as via Zune.
I tried to make a hard reset to eliminate the possibility that the unlock (rootacces) had anything to do with it... same problem.
As I understand I should go back to the Samsung Omnia 7 version as it came in the box, right? After that letting Zune handle the complete update from scratch? Well... how do I do that? I have found som threads but I´m not really sure witch one to use...
Can someone please give me some directions to get this to work? What files do I need and how do I restore the phone to it´s original state? (in the box-state).
I bought the phone secondhand since I use 3 (Three) in Sweden. I have had NO problem with it at all... But I get soooo anoyed with Zune telling me to update... so I thought "What the heck!?"...
Well... I guess I sorted it myself... followed the guide here: http://forum.xda-developers.com/showpost.php?p=11713948&postcount=1
I have to admit I was really uncomfortable doing this... But after getting the correct files downloaded it was really easy. The phone downgraded to the first version of Windows Phone 7... I screamed out loud when I saw the old green round Windowslogo... but after a couple og updates via Zune Mango was installed... the the updates rolled on and now I´m on the latest release. I feel quite happy since I don´t have to do this when WP 7.8 arrives this fall.

Help please. Update rooted flex2 with old software vers

My Flex2 is LS996ZV4, i bought it in Cuba. It never got any OTA update since i rooted it very early and the software update notification didnt showed up there. Im living now in Peru and the notification does show up (by the way it can be seen in the screenshot), but... the update does not work because the phone is rooted and i find no way to unroot it due to its old software version(V4). Im in some kind of a loophole here
In the mean time, my phone overheat and lags like crazy! And i've been using it like this for almost a year now...
I asked this before, and i got no response, guess is not something easy to do.
Thanks in advance. Any tips will be higly appreciated.
Do some search in the forum and you will find similar threads about this issue for H950 or other variants check if it applies to your model or try it on your own if it works good then you are fine if it doesnt you will have to wait for professional support by other members who have exp with this device
Thanks for the tip @yeyoo. Im starting to believe there is no solution at hand...
I have searched... and almost every advice i read implies going back flashing the stock image and unrooting. But i cant do It because i cant find an image of this old software vers.(v4) to download.
I think you dont need the same version you have you can flash higher version kdz easily and it will remove root automaticly or you can try to update through lg mobile support tool on a pc

bought phone from becetech wont update firmware

im sorry if this is in the wrong section but ,ok so i bought an open box galaxy s6 from becetech online and it would not let me update the firmware past 5.1.1 which made me a bit suss, downloaded root checker app and it came too me rooted. apart from not being able to update the firmware past 5.1.1 as far as im aware the phone has no issues and works perfectly fine. i downloaded the *samsung* phone info app, in general under manufacturer it says Samsung/verizon so im assuming that is part of the reason they rooted the phone as it needed to be unlocked from verizon to be refurbished? so what i want to know is how do i find out exactly what becetech have done to the phone and is there an easy way for me to update the firmware to nougat or at least marshmallow without stuffing the phone, like i said the phones running fine its just really bugging me not being to update. obviously im not able to work it out myself but i can follow instructions so any help from someone would be greatly appreciated so thank you in advance.

Could someone with a bit more knowledge please tell me if the reason I can't update the firmware is because the firmware csc is TGY when I'm in Australia or just because it's rooted or what? I'm getting no answers from the company who I bought it off

Are you trying to update via the phone update feature? If so this won't work as rooting disabled the ability Update using ota
First I tried OTA then downloaded samsung smart switch and gave that a go both no good. What I want to know is, if they had to root the phone to refurbish it will it brick it if I try to update? Won't it reset all the company I bought it off has done to it to refurbish it? Which I'm guessing is quite a process as when I look at the open source licenses there's a long list of files that have been changed. It just sucks that it's locked to a three year old version of the firmware that I'm worried apps will start to stop supporting in the near future? Apart from that I can not fault the phone there's been no problems, maybe I'm asking a bit much for a $400 phone?

From what I can tell you have a g920v variant if the phone Shows Verizon but the sure fire way to know what variant you have is turn the phone off once off hold home-power-volume down, this will take you to download mode but should tell you your variant. You don't need to root a phone to refurbish It, you can flash Stock firmwares via Odin. I really don't know why they would have Rooted It tbh, you'd need to contact them, but I know for sure you can manually download the latest Verizon firmware and the phone should work. Maybe they Rooted it as part of making it network unlocked, o really can't say
Ok I tried that and a bright blue screen came up warning about custom OS then press up volume for download and down volume for reset? I just pressed down as there was no other info on the screen but it does say it's a sm-g920v in the settings as well as the root checker app. Another thing was I did ring samsung support gave them the serial number and IMEI and they said an authorized modification had been done on the phone but could offer no other support as it wasn't an Australian phone. I'll keep trying to get some info out of the company I bought it off and try to sort it out thanks for your help :good:

HTC U11 Oreo update got canceled on 24%

Hi Everyone,
im sorry if this is in the wrong section. I wasn't able to find the right section to ask for help about getting this update done..
Well here is my story:
Tried to update from 7.1.1 (software Nr: 1.27.401.11) to 8.0 and got an undescribed error symbol. No reason why it stopped or something.
I contacted HTC and after 2 Weeks waiting they respond with "send me your IMEI"
After another 2 weeks they told me to set it back to producer settings and try again.
I did it and nothing changes. Im exhausted I just want to get this update or at least stop those stupid reminders of a new update...
Google can't find good results.
My HTC U11 is a Dual-SIM version if this is important to know. Oh and its unbranded.
hope you guys have some advise.
Thank you in advance!
I had the same issue. I have unlocked bootloader and twrp recovery with magisk. After returning to stock recovery and boot, uninstalling magisk still had 24% issue. I installed stock system with ruu. After that I updated easly to oreo. All data will be lost if you want this method.
Hi thanks for replying. Does this root the System? I have no clue and dont want to lose guarantee.
If you have stock system with lock bootloader then I don't know why you can't install oreo. I unlocked bootloader so my guarantee is void anyway. I just told you what I did in my case. I don't know if you can install ruu with lock bootloader. Maybe someone smarter can tell you something about guarantee.
You can stop the update notification by pressing long on the updation notification then press advance settings or something like that (I have a German Android OS) , then click on the updater icon and then you should be at app settings of the updater, just force close the app. After that you should never see the update notification until you restart your device
same problem
hello. I have same problem. Did you solve?
