[Q] OTA Update on rooted GT-I9105P

Hi guys, a couple of months ago I've rooted my new S2+ and after Alex posted the new 4.2.2 I've flashed my device with RDS_GT-I9105P-XEO-I9105PXXAMC2 (topic here GT-I9105/I9105P Stock Prerooted Firmware Without loss of warranty(4.2.2) http://forum.xda-developers.com/showthread.php?t=2334103).
So far it is working perfect! This week I've received a notification, that there is a new update available OTA for my device, so I've decided to download and install it. I've downloaded it, the phone restarts and starts to install the "new update", but at 25% shows an error (the Android guy wearing the red triangle etc. and reboots automatically).
After the restart the OS boots normally and is working OK as previous.
My question is: Since my phone has a prerooted stock FW (4.2.2) and is rooted at the same time running CWM, why I can't install the latest updates OTA?
If CW is causing this, why am I able to get the OTA update notification?
Thanks for the replies.

that is because it is a modded firmware

I understand that the FW is modded, as the previous one (4.1.2), which I've downloaded from here and installed on my G2+. But with 4.1.2 at that time I wasn't able to check for any updates for my OS. Every time I've checked manually for updates, the OS gave me error message, that this is not possible. And now with 4.2.2 I am not only able to check if my FW is the latest, but also to download and install 1/4 of the updates. I am trying to find the algorithm here.

I will say it again
It is not possible to check for updates because the Firmware is modded and not original anymore that's why!!!

Hi "safariking",
In the current situation we have two identically modded FWs, but a different outcome.
It's very nice of you to take the time to answer my question so fully That's why I'd like to thank you for the effort. Herewith I am closing the topic.
Cheers.

chill down everyone safari bro,this guy trying to say he got updated with mod fw,just when reach certain percent,the downloaded file seems corrupted. Now i understand mod fw can't even received the ota file,but how this process is allowed, and what happened with the ota file he downloaded?
either way,it's pointless,1st the phone fail to update completely(stuck at 25%), 2nd i don't think this problem can be solved.
cheers everyone~ :highfive:

Hi Nick,
Thanks for your reply. You are reading my mind. The issue is really interesting & I think it is worth discussing this.
Safari is right, when he says that FW upgrade OTA for customized ROM is not possible. This is of course true and no one has ever doubted it. This is why when I had the 4.1.2 installed on my G2+ no update was even possible. Droid detects immediately, that the OS has been modified and that you are not running stock ROM.
Okay, so far so good.
Now I have pre-rooted 4.2.2 installed on my phone. When I hit the "Check for update button" it detects that my OS is genuine (although it is not), downloads the whole update package (see screenshot), restarts the phone (part of the update process) and starts installing the update. When the installation reaches 25%, an error message appears saying, that an error has occurred. The phone restarts and loads the "old" OS.
I have tested this a several times and it always hangs on 25%.
The question is NOT why I CAN'T install OTA updates on modified ROM. The question is why I CAN download and install OTA updates on modified ROM.
My suggestion is that:
ROM 1 (4.1.2) had a modified kernel. That's why the OTA updates were not possible.
ROM 2 (4.2.2) is pre-rooted. And I assume it is just stock FW (kernel not modified) with few modifications in the user permissions. This would explain the OTA update and why it reaches download mode and hangs on 25% of the installation.
I hope this brings more clarification to the situation and this would be useful to all members of the forum.
Cheers!:highfive:

I have randomly come across and read posts and topics on this in the other devices' forum.
If I remember correctly, it is the custom recovery, i.e Cwm or twrp that blocks or interrupts the OTA process. 2 reasons why: you'll lose root access if the update went through. Secondly, if a user freezes or uninstalls stock apps like S Voice, Chat On etc, there will be trouble.
There are some ways of allowing an OTA to get pass a custom recovery. I think TWRP has this feature. Again, I stand corrected here lol.
Heard of OTA Root Keeper but no idea how it works

I think you will get the 5.0.1 OTA update soon instead of 5.0.0. You can always flash the Lollipop image manualy in fastboot.

Has google stopped giving 5.0.0 update?

Yup there are some issues like battery drain, wifi connection drops and sms/mms issues with 5.0.0, thats why they pulled the OTA i guess, 5.0.1 should fix these issues.

Not got android 5.0.1 too

Flash the OTA via sideload in recovery or flash from the extracted 5.0.1 factory image the bootloader, boot, system and recovery img`s in fastboot if you don`t want to wait for the OTA. Link to the OTA http://forum.xda-developers.com/google-nexus-5/general/info-nexus-5-ota-help-desk-t2523217.

Nexus 5 still no OTA lollipop update

Good day,
Well, my wife has the Nexus 5 and her phone still hasn't got the 5.0 lollipop update by OTA. Which is wierd. I would do the manually image update on her phone. But she doesn't want to loose her game saves and all that crap. I am in Canada. Anyone else in Canada not get the lollipop update yet as well? And is there a work around. Probably a far shot of a question.
Thanks

Lol is everything stock?

my friend is having the same issue
i rooted my buddies nexus 5 and flashed the factory google image for 5.0, now that the patch has come out he wanted me to revert him back to stock
so i took him back to 4.4.4 where he was before the factory image.
he wasnt getting the update.
i read somewhere else that the bootloader has to be re-locked for ota's to work so i did that too. still no update.

Got my nexus today, hoping for lollipop update, and it says 4.4.4 is the latest one :/

Yup. Her phone is stock. Nothing done to it.

I got kind of the same problem. Got my OTA notification maybe 3 weeks ago. I didn't want to upgrade the phone just yet, had been hearing some battery issues and wanted to fint out if it was worth to upgrade.
Today I decided I would do the upgrade since the 5.0.1 has been moved out, I thought that 5.0.1 would take care of the first bugs. But when I try to upgrade it says I have the latest version. I'm on 4.4.4 stock, no root.
I did hide the notification for the updates right after I got the first notifications for it, but I have been checking back from time to time to see that the upgrade was in fact still availible on my phone. It was maybe a week ago, but not anymore.
Does anybody know if I'm supposed to do something to be able to upgrade now, or should I just wait?
Thanks

Should just be a waiting game.

Don't know if your answer was to me. But if it was, do you know Why the update is gone now? Any reason for that?

Yeah something vent wrong
I had kitkat 4.4.4 on my neuxs 5 Rooted. so when OTA lollipop came i went back to stock rom and updated My N5 from 4.0 to all the way 5.0 Lollipop.
but i had to go back to Kitkat because no game hacking software is working with lolipop so i wen back to 4.4.4.
Now again i m trying to get OTA update for 5.0 (no root) its not not showing me in update its stuck on 4.4.4. and its says that my software is up to date.
I am from Toronto Canada. I guess OTA update is gone for CANADA.

Ya, I don't know why her phone hasn't gotten it yet. I may have to unlock the bootloader and do it manually!!!!

Problem is that if her bootloader wasn't already unlocked, the act of unlocking prompts the phone to erase all userdata. Which is why you should always unlock the bootloader right away with a phone before doing anything.

I've read on reddit, that maybe cause it's 5.0.1 out, we have to wait in line again for it to become available on our devices, the same reason is with the guy who dismissed his notification

Sorry yes it was to you. Because the updates are delivered in batches. If you ignore the update for so long, you go to the back of the queue until it's your turn again.

OTA Update
Hey guys let us know if OTA update working again or not cos 5.0.1 is released i think it should work now...
any one?

this still doesn't explain why my wife's Nexus 5 is still on 4.4.4 and hasn't receiving the lollipop udate as of yet. It's been out for a bit now. This is screwed up beyond beleive!!!

You could always just purchase one those backup apps like Titanium that does not require root and then save everything. This way you could do a manual side load.

It does explain it.
OTA system is kinda of a lottery - either your device is a winner, or it isn't.
Just freaking get the OTA update zip and sideload it. You won't need to unlock bootloader for that.

Got mine a day later, was prompted to update to 4.4.3 followed by 4.4.4 immediately. No 5.0 or 5.0.1 updates yet but my nexus 4 is already on 5.0.1? Guess we'll have to wait.

OTA Update Working now
Hey guys OTA update is working now...

Were you previously under kitkat or did you get the OTA update from 5.0 to 5.0.1?
EDIT: Nevermind (at least for me), tired of waiting, I finally decided to manually load the OTA by following the tutorial here:
http://www.talkandroid.com/guides/b...on-your-nexus-device-download-links-included/
The funny thing is that after my phone was manually updated to 5.0, I automatically received the OTA for 5.0.1

Lollipop update- where are you ?

About 3 weeks i installed the Kitkat rom stock on my N5.
Today i tried to see something about the OTA update to Lollipop, and surprisingly i saw isn't it arrived to me.
I just tried to Clear Data from the Google Services Framework- still the same.
Somebody know how can i get it ?
Thanks for answering,
Tal.

Are you rooted? If so, you'll need to unroot to take the OTA.
Sideload this via ADB: clickity-click.
Wait. I think you'll need to sideload the 5.0 update first, and then do the one I linked for 5.0.1. Can somebody confirm this?

First of all don't clear Google services framework data that messes up stuff pretty bad. Second d, this should be in q and a section. Third just flash the 5.0.1 factory images or there is a flash able zip out if you're rooted with custom recovery.

I agree wid op...
I have used kk for past 2-3 weeks... And notification never popped out...
I flashed manually 5.0 and i got ota for 5.0.1 ... I dont knw whats up wid google ota system...

5.0 ota seems pulled, Got 3 N5 which all have the ota prompt before, but none of them get the ota message now.

So isn't it only on my device. OK.
Thanks !!

It never was your device. The OTA is rolling out in phases (not sure it's true that it got pulled but I could be wrong)... Just flash the factory images or lollipop stock ROM flashable zip. There are plenty of threads about this in the stickies...

VZ OTA Update - New release?

Phone is S-off, Rooted
Running Android 5.0.1
TWRP 2.8.5.0
My screen prior to going into recovery states: Software Status "Official"
I'm getting the VZ software update notifications. Does anybody have any idea what this update is for? When it has tried to auto update in the past, it has failed, which is expected.
Wasn't sure I needed to bother with updating my phone or grabbing an updated ROM for anything groundbreaking.
Thanks!

Nevermind, just googled the OTA software update number (4.17.605.5_R4) and it relates to Stagefright patch. I am currently on 4.17.605.5
Is it something to be concerned with leaving as is or go ahead and update?.
Thanks
