First try Hard Reset, if that wont help, the go back to stock 8.1 update 2 (with Windows Device Recovery Tool), then with slow ring update it to 10586.11. For now use only what Microsoft offers, dont experiment for now, because you'll have a problem again. There is a lot of bugs on no official builds.

Hello Opus Dei, ive followed your instructions to the letter but still cant leave flight mode. Do you have anymore ideas on how i can releave my problem? I dont know if this info will help you any - I'm using a Microsoft Lumia640 LTE, i was on stock rom then i installed the insiders app & updated my phone but i used the "fast" method. The first update was fine then a couple of days later i had another update note so i did that but when the update was finished & the fone went to reboot itself it just kept boot-looping, i left it doing this overnite but still no joy so i used the "install 105##" but when the fone rebooted it was stuck in flight mode & i cant get round it & i'd bought the fone for my sons birthday which is this week so im willing to try any of your instructions to solve the problem. Im hoping you or anybody else has a solution to get me out of this situation. Thanks to all the helpers - Dave.
Ive noticed that in the "extras & info" section it says "Mobile Operator 000-GB" which ive found to mean open network but my fone was bought locked to Vodafone & when i turn it on its branded with Vodafone. Could this be anything to do with my problem?

o2 XDA Mini II - Looping Boot issue.

Hello,
I received an XDA Mini II and am having a few issues. Firstly the person who had it 'attempted' installing Windows Mobile 6 that is available on torrent and ran the file 'EnterBL' and it went into boot loader (and goes into it nearly always). However now I have it was able to 'hard reboot' it and get the normal screen to come up and it seems to have reset it since it is taking me through all the welcome stuff.
But it goes to install all the programs and then reboots back into bootloader and cycles through all of that again.
What would be the best option. I am happy putting Windows Mobile 2003 back on but what files do I need to do this? is it possible to put WM6 (from torrent) on it with what comes in that torrent?
I am sorry if this is in the wrong section.
Thank you for any help...
UPDATE: I managed to get back into the phone by removing the battery before it did the 'customising' and then when it booted it came up okay. However when ever I reboot it it goes back into 'Serial' bootloader mode and then I have to do the setup all over again.
How can I stop this?

Its a bad flash,extended rom has got corrupted,download the official carrier's rom from its official website for the make & model of your phone and reflash it.It'll srart working to default status.After that if you wish you can upgrade to any wm6 latest rom by following the correct unlocking and upgrading method as per your device.
Secondly,don't download Roms from Torrents,as they usually are corrupt or virus infected.Always get Roms from here from xda-developers forum or from the official carrier's website.
Good luck

So... i bricked my Galaxy Tab... HELP!!!

So I was retarded and followed the instructions (or started to) on androidadvices dot com/how-to-update-samsung-galaxy-tab-to-stable-gingerbread-2-3-3-firmware
My Tablet will not boot past the T-Mobile logo.......... they are being assholes and telling me i need to deal with samsung ......... who told me it would be 6-8 weeks for a replacement........ is there ANYONE out there that can help me with just resetting it???
If you can get to the T_Mobile logo, you probably have a working bootloader and that mean you just need to flash the correct firmware for you device.
In short words, go to samfirmware.com and download the right firmware for your tablet model.
Once you have the firmware, flash them to your tablet with 'odin' (flash software, that you can also get in the mentioned website).
This should solve the problem.
If this works I will love you.
So i am obviously more retarded than I thought pedrohfsd ........ I have an SGH-T849 and i cannot FIND the firmware on that site..... seriously? UGH
pm me i'll tell you what to do , with th stock firmware for Tmobile , i helped someone before 2days he had same tab with you ) and same problem

You sir, are brilliant.
I wasn't able to locate the firmware on the samfirmware.com but I DID find it on XDA from another user. Put phone into download mode... waited till the little box in Odin turned yellow and loaded that badboy on there. After about 5 minutes it was back into the 2.2 OS again. The only problem that I had was with programs that had been installed before and loaded at boot (Just had to uninstall / reinstall) But for the most part its back to the way it was.
Thanks so much for your help!
You too Kosh, as I am sure you were going to walk me through exactly what I fumbled through on my own (I'm lucky I didn't blow anything up haha)
NO more attempts to get 2.3 on this badboy!
Thanks again all <3
I'm glad to hear that KalKainen, the first time i soft bricked my phone i got desperate too.
But after some weeks i saw the inumerous progressions that people develop in custom roms here in xda, and flashed the whole thing again =P.

Amen man..... desprate is about right.. haha... now if i could only figure out why i have to CONSTANTLY reboot it in order to restore network service (Even though I have 3g and full bars... no text messages send / come in and programs that use data error out... ) I would be happy. This has been happening for the last 4 months badly enough that I can have to reset it 10 times in a 2 hour period >.< I cant even put it into flight mode.... but after I TRY putting it into flight mode and then reboot it... it comes BACK in flight mode.... I hoped the reinstall of the firmware would fix it.. but alas..... still plagued. AT LEAST IT WORKS THOUGH!!

[Q] samsung ATIV S rebooting all the time!!

Ok.
first off, Hii!! this is my first ever time writing on XDA.
Any way, i know this is not a new issue.. but my ATIV S is rebooting every 5 seconds after the 8.1 update via preview for developers.....
i did a lot of digging before writing here and found this thread : http://forum.xda-developers.com/showthread.php?t=2718023
I followed the instructions and flashed the GT-I8750_DXBMJ1_R_signed ROM along side the GT-I8750_VJALL3_P csc (this is the only combination that gave me some results.
After flashing, my phone did manage to boot up finally but with a twist. Trying to restart the phone sends me back to the boot loop forcing me to reflash everything again.
i tried the tip from the thread to download the preview for developers app and try to update the phone again (claiming it will resolve the issue) but as soon as the phone goes to reboot before the update the boot loop comes back and we're back to squire one.... so i'm kinda stuck.... is there any kind of FIX i can try to help me sad situation? :crying::crying::crying::crying:
I've had a lot of issues with my Ativ S as well.
Your rebooting issue seems recognizable, maybe this thread will help : https://social.msdn.microsoft.com/F...ime-after-wp-81-update?forum=winphoneosissues
Anyway, I'm on the latest Developer Preview update, my Firmware version is : 2424.14.9.3
It seems the phone is much more stable now, however i'm only using this phone for development, there is no sim card present anymore.
Switched to a new Nokia for my main device.
Advice : If you want a decent Windows Phone, buy a Nokia, not a Samsung or HTC.
Thank you for the reply!
i did some more digging and found that flashing the GDR2 FW 2424 actually helps. after that the is a need to update the phone to the official GDR3 update in the phone updater in settings. i am trying that as we speak and really hope it will work
BTW this ATIV S is my backup phone and not my daily driver (i use a Galaxy s4) i just wanna fix it up to use as my work phone. my trust in windows phone is gone for now XD
EDIT: OK, so i followed the thread and applied the instructions...
at first, i flashed the GDR2 official ROM with the instructed csc file and everything booted up well. at this point they say that if the phone is to be restarted the boot loop will come back (it did when i tested it)
afterwards, i installed the preview for developers app and started updating to the official GDR3 update as instructed. it finished up and booted up well. the next step was to update to 8.1... i did and at first it worked well but as soon as i disconnected the USB cable, the loop returned again. (if i connect the USB cable back it's booting up normally)
BTW i tried doing it all from scratch and noticed that in every step of the process, if i disconnect the cable the loop come's back and disappears as soon as i plug it back in... anyone has any idea what to do next?

FRUSTRATED :( .. gear live gives ERROR, TRY AGAIN when attempting system update

unknown to me, I purchased a Gear Live that was developer edition and would not update... I used one of the tutorials on the site to get it back to 4.4 ( thank you ) ... it will boot now and connect to the phone, but when I hit SYSTEM UPDATE it displays a big GREY X and then says ERROR, TRY AGAIN....How can I get it to update ?? I have reset the watch numerous times and as I say, have finally got it to software version 4.4W from the developer edition 4.4W1.... thank you for any help you can give me...I also tried Samsung Kies to update it but it wont recognize the watch
Did you try to reset your Gear Live with this tool already?
http://forum.xda-developers.com/gear-live/development/utility-gear-live-watch-tool-t2846696
I had a similar problem once and could fix it using that thing.
Got it figured out...spent 6 hours trying to get it to download the update..reflashed, rebooted, used the tool, EVERYTHING !!! Gave up on it at work as i kept getting DOWNLOADING,OOPS SOMETHING WENT WRONG, TRY AGAIN ....ONLY to find out that when i left work and tried downloading AGAIN away from the works network, IT DOENLOADED FINE ! Something on the network blocked it i guess and would not let it download. ARGHHH ! Thanks for your help !
