[Q] Help my Arc unable to boot?? - Xperia Arc Q&A, Help & Troubleshooting

Ok I was running version .145 (rooted) with unlocked bootloader already. I am just trying to update my version to the latest one. So what I did, I download the stock .145 version and flash them using Flashtool. After flashing the phone booted just fine. After that, I go to update the software from the setting option. The phone downloaded the software and eventually install it. Since then I dont know why the phone is unable to reboot itself??? I have tried to re-flash again using the flash tool but still unable to boot my phone??? (seem to be flash ok, no error messages what so ever). Can anyone help me, how to boot my phone again?? or to make it work normal again?? Thank you.

Ok, think I finally fixed it....thanks to the following thread:
http://forum.xda-developers.com/showthread.php?t=1126358
Seemed like I bricked my phone....thank god it work again...

Everytime bootloader is unlocked, OTA will brick the phone. That's a fact. Anyway at least you figured out the solution.

Hey..
Nice that you fixed it..
Please read the Namaste guide sticky in Genral forums for info on locked vs unlocked bootloader..
OTA update for any unlocked bootloader will end up with a bricked phone.. So instaed simply flash the latest ROM ftf and then flash a rooted img.. Check forums for threads on tutorials for this..

And i can't use what i want on a custom rom but i can on the stock.
Can someone explain to me how to go back to stock?
Thanks,
Thomas

Thanks for the Reply.
I currently flashed my Phone with this rom.
But i currently got another problem : My phone gives me the message that there is a new update. But when i try to install it, i get an error that it's not possible.
Using a Xperia S.
you cant update when you are on unlocked bootloader, you need to relocked first.

You need to relock only when going to use SUS/PCC. Flashtool, no need.
yeah , but he is asking that he cant update his phone even though it prompts him with new firmware available.

Don't flash ICS - the ICS bootloader is locked and will throw up a security error if you try and install a custom recovery.
Otherwise the steps are correct.

ok, so skip first one, just root...
any normal root option for 2.3.5?
you can root then install CWM recovery if you think that your device doesn't have secure bootloader.
if you try to boot into CWM recovery and you get a fast boot error, it means you have to unbrick using the unbricking guides found in the general forums, then flash cm10.1
---------- Post added at 07:39 PM ---------- Previous post was at 07:38 PM ----------
dont try to install CM 10.1 if u aren't comfortable performing steps on unbricking guides, read one of them first then decide.

if you try to boot into CWM recovery with a secure bootloader your phone gets bricked, thats why i say dont do it unless ur comfortable unbricking. make sure ur phone is fully charged when u try to boot into cwm for first time
This method of rooting and installing CWM worked for me on a Bell P930: http://forum.xda-developers.com/showthread.php?t=1784709
I am running Liquid Nitro v7 and intend to try CM10.1 RC2 later.

htc one m8 "variant system version" !!!!

i have htc one m8 unbranded ... i bought it with nocturnal software !! it weird but i go back to stock using ruu "t-mobile" version cause i didn't find the unbranded version ... now after download the new ota update 4.4.4 eye ... i got message
"variant system version" >> you are running a modified version,.. for protection cannot update, plz revert to htc software system
the screenshot attach.
my current info:
locked bootloader
S-OFF
CID:11111111
plz help me XDA :fingers-crossed:
If you a custom recovery, or xposed, or have altered/removed any system apps, the Ota will fail.
You are s-off and super CID. Why not just flash the new firmware manually?
See the "flashing firmware without the panic attacks" guide in development section. ?
thank you sir .. flash firmware will get me to stock and update ota with no problem or what ??
btw which firmware to download ... or my super cid will accept any firmware number !!!
my now software no. 2.22.531.6 not in the "flashing firmware without the panic attacks" ??
am sry just changed from iphone, and i barely understand you

Don't do it!
Seriously, do not go stock. Just unlock your bootloader (can you be s off and supercid without? I never knew).
Once you do that, you can flash firmware from any carrier, then flash any updated ROM for that version.
You will never have to wait for carrier updates.
If you go stock, you will always be playing catch-up.
yes am sure of that am "locked" "S-oFF" and "CID:11111111" but i don't understand what a firmware will do to me !!!!!
but i understand this: unlock the bootloader ,,, then i will download any firmware with any number ?? really ? .. then download any custom rom ? like viper one...
and then if i do that i will recive 4.4.4 updates without any problems ? i think NO, custom roms prevent ota updates, so i have to check the sites of the rom from time to time to update ??
thank you
ex *i can't get viper one 3 rom untill updated to 4.4.4
Flashing firmware will not return you to stock But flashing the latest firmware will allow you to flash the latest version of roms that require the new firmware.
---------- Post added at 07:59 AM ---------- Previous post was at 07:55 AM ----------
But how can you have a custom recovery (to flash roms) if you didn't unlock user bootloader?
I'm confused. Lol
If you can find a stock backup, you can restore that to get back to stock, then flash your stock recovery.
Again, Need the custom recovery to use the backup tho.

no its locked bootloader with stock recovery, s-off and super cid !!!
i tried to get back to stock using backup recovery but i failed,, and no ruu for the international unlocked yet ... i just want any custom rom with 4.4.4 and be able to upgrade to android L when it release .... thank you mate

Well it looks like to me that you'll be in the same situation as me. And that is that the easiest and probably quickest way we'll get L, is to flash a custom L Sense Rom. Or Aosp if you prefer that. And we'll be able to do that, cause we're s-off and Super CID. ?
Will likely need to update firmware for L too. Which again is simple with Super CID.
So, for right now, you do need to unlock your bootloader to flash a custom recovery. My vote is twrp. You need to do this to flash a 4.4.4 rom.
Also, you need to be on the latest firmware for the 4.4.4 roms.
All that said, if you want to wait and get the L OTA... You need to be stock and I believe you need your original CID to receive the Ota. I could be wrong on that. I've never done an ota on my M8...any device actually. I've always manually flashed new versions or used Roms. ?
So for now unlock bootloader and get the latest firmware then flash 4.4.4 rom ?? Where did i find that 4.4.4 rom ??

Depends on your model/carrier which roms you use.... But in the development sections.
And firmware needs to be current or there will be issues on 4.4.4 roms.
The "flashing firmware without the panic attacks" thread in the general m8 development section will help you update. ?
Am unbranded international single sim .. give ne any link to the roms 4.4.4 and be greatful
Lots of roms here... I never recommend particular roms...
http://forum.xda-developers.com/htc-one-m8/development
Read the first post to see about it, and decide what you like.
Backup what you have in recovery first... Then follow the rom install instructions. That's it.

You need the firmware, that's all. Then you can install Viperone's 4.4.4. That's what I'm running.
And you don't have to unlock the bootloader. Just flash the new firmware and then flash the ROM.
You can get firmware downloads, and instructions on how to flash them here.
This method is the safest.
EDIT: Looks like I'm a little late with my reply.
thank you "xunholyx" ... i will do a firmware update and hope that's will work, but how do i flash a viperone custom rom with a locked bootloader !!!
i thought i have to unlock, then twrp then flash it !!!! little confused

It was me who was confused. Sorry. You can flash the firmware, but not the ROM. You'll have to unlock for that.

There's nothing to be afraid of. As long as you follow instructions well, you will never have a problem.
Have fun flashing! You're going to love it. And ViperOne is a real good choice if you want to keep Sense. I'm running it, and it is great!

Find the thread for your stock firmware and see if it is available there. This happens because of root and/or the unlocked bootloader. You have to unroot and possibly relock the bootloader to be able to take OtA updates.
Sent from my Moto G6 Plus using Tapatalk
Same issue here .
If your bootloader is unlocked or if you do not have the stock recovery anymore then the update will fail. If your rooted then look through your device for the update package and upload it online for others to see.
I've tried flashing the stock firmware but get same result. Where do I get the stock recovery to fix the issue?
I haven't unlocked neither rooted my moto g6 play yet, I received the update notification this morning , I've updated it with no issues ( around 500mb). Update is Android security patch level , 1 September 2018 , build number : OPP27.91-143

I thought the same, but flashed stock firmware and it won't update by ota.i can download it it but it fails.
unlocked bootloader won't make you unable to do the update. only stalling custom recovery and/or rooting phone. as soon as I got this update by the beginning of the month, I just reflashed stock firmware and did the update.
