[Q] Am i posting it wrong?

Hi
I'm new to forums. But I like this one. People are discussing stuff instead of complaining about their devices. I'm learning a lot. But I still need an answer to my question. And I don't think it's very complex. So I thought maybe I'm posting it wrong. Is there anything else one should do to get there post replied to. Like tagging it in some way. It's not a complaint. I really wanna know to be able ro enjoy the forum fully.
Cheers
You don't need to do anything special. What is your question?
Oh cool
Hi
Thank you very much indeed for replying. I was just wondering if it was safe to update a rooted galaxy 8.9. I got the update message in my settings so it's a proper factory official update but I've never done it before so I was a bit worried after having read about some bricked phones and (don't even know what bricked means but sounds scary).
And if you could answer another question as well please that would be really nice.
Recently my tablet crashed in a weird way so I had to reinstall every single application on my tablet. After the crash every single app was force closing and it asked me for the date and the region. Since then it crashes not very often but regularly. So I thought maybe I need to do a hard reset or even reflash the rom. But now, as far as understand, updating my firmware should sort it out for me. Am I right in thinking so?
Any advice would be greatly appreciated.
I have not heard of anyone who has bricked their gt8.9 updating a rooted device. You possible loose root when you update, but you can just flash the root.zip again. In worst case you end up with a soft brick, this can be fixed with flashing stock firmware with Odin.
If you are having random crashes, i would start with factory reset. Please dont forget to backup before, because factory reset will delete everything on your tablet.
Update to latest version. Latest versions are a lot better then early builds.
Hope this helps.
Thank you very much indeed.
Will I be alright following the instructions in this forum's guide on how to use the ODIN?

Yes, but i don't think you are going to need Odin. Just click update. If you get any problems, then let us know and I'm sure that there is someone here who will help you restore stock firmware if needed.
This thread has nothing to do with me and I have nothing to contribute other than to say that you're a class act, poisike. Too many people on XDA think it's OK to be rude to newcomers and that obnoxious comments about using search add value to the board. +6 internets to you.

Need some Help!! Please

Okay.... Well, I'm a totally new to the android world and I see everyone talking about Rooting and the CyanogenMod. alright. I got ma phone rooted and I understood that with the rooted device we can have the access to do whatever we want to the apps in our own phones and much more but i don't know what else can I do with my rooted G-S4, rather than just removing the unwanted apps... I have some serious questions and I hope to get the answers for all of them... I appreciate all of your help guys
1. What is the "CyanogenMod" and what's good about it?
2. Why we need it?
3. Should my device be rooted to get it?
And IF I'm gonna need to change something in ma rooted software, PLEASE tell me... Again, I'm really thankful for every answer I get

i was wondering if anyone has successfully downgraded back to kitkat with their tablet. and if so, what are the steps? i'm not completely computer illiterate, but i am very new to android.
any help would be very appreciated. :fingers-crossed:
Need solution for this too

Searching ROM "990.43.74.XT890.Retail.en.EU"

Hi all,
I'm desperately looking for a download of "Blur_Version.990.43.74.XT890.Retail.en.EU". I have searched all over the web, the dark web and even the 9th circle of hell but to no avail.
Here are some more information about the installed Android version:
System version: 990.43.74.XT890.Retail.en.EU
Android version: 4.4.2
Kernel version: 3.0.34+ [email protected] #1 Tue Jan 6 13:08:54 CST 2015
Build number: KIA20.74
I need to do a recovery of my installed Android version, but I don't want to root my device. I believe the recovery will fix issues with the battery. Android seems to only get erratic readings of the charge status and thus shuts the device down within minutes or even seconds after disconnecting it from the charger. I read elsewhere that this is not necessarily a hardware issue and some people were able to fix this problem by recovering the same Android version they already had installed.
Does anyone still have a zip of this OTA upgrade and could kindly provide it to me? Or maybe someone knows of a link I havn't found yet? Any help would be greatly appreciated.
Same here!
Hi
I have this exact same problem after recently updating to KitKat OTA. I would also like to do a recovery from a stock ROM but can't find one.
Would appreciate a pointer to stock ROM:. 990.43.74.XT890.Orange.en.GB
Have heard that downgrading to JB stock ROM will brick my phone.
Any help greatly appreciated, thanks.
Hi,
I have the same problem.
Please keep an eye on this thread
http://forum.xda-developers.com/razr-i/development/razr-xt890-4-4-2-eu-ota-update- t3092041/page4
And also on the motorola forums here
https://forums.lenovo.com/t5/MOTOROLA-RAZR-i/Motorola-Razr-i-Upgrade-Update/td-p/3154317/highlight/false/page/86
This seems to be effecting several people now - hopefully the more people who post in these threads will help us get a fix.
Does anyone have a solution for this? Please help! My Motorola Razr i (xt890) has developed the same problem described in this and other earlier threads - very erratic battery, jumps from 100%-4%-47%-9% etc. Phone is unusable, but was previously working great and I just want to fix it. I have zero technical knowledge so would love to know if anyone has managed to re-install (or upgrade or downgrade) ROM without bricking the phone.
same problem here since 2 days. where to get that flash ? 990.43.74.xt890.retail.en.eu
please help me!
I'm also in the same boat. I'd purposely not updated from ICS and still not sure how this update has occurred, regardless I now have the same battery spike issues and have been scouring the web for a copy of: 990.43.74.XT890.Retail.en.GB to try to fix it.
Can anyone please point me in the right direction?
