[Q] unlock bootloader and OTA

I know some will say its answered somewhere in the forum , but i searched and it didnt give me a clear answer,
if i unlocked the bootloader and installed CWM and rooted my phone wothout flashing a new ROM, will i lose the ability to recive OTAs?
one more thing (sorry im asking alot) unlocking bootloader says that it will erase all phone data , does that include the SD card part of our phone since its internal ? will i lose the photos stored , or its just like flashing an RUU
Thank you so much

Firstly, yes you will lose the ability to receive OTA updates. With regards to the SD Card this will remain untouched.

Are you planning on using a stock rom or a custom rom?
EDIT: Sorry didn't read properly. Yes if you are using stock rom then you should be able to download the OTA update from somewhere on XDA. If you are using a custom rom then the chances are the Dev would have already updated there rom to the latest base.

Sorry to ask additional question:
If I intended to use stock ROM only and continue to receive OTA update but with rooted phone. What is the best suggestion?

in my understanding , you will have to unlock the bootloader and install a CWM recovery to root your phone and keep the stock ROM, but you will have to download and install the OTAs manually

Just flash back the stock recovery, relock the bootloader, reboot the phone, receive OTA update and install. Then re-root process again to have root access.

Just wonder where to find the stock recovery? If my ROM is 1.28.xxxx then I must use back the 1.28.xxx stock recovery img file, isn't it? Where should I look for the exact stock recovery img file?

[Q] JB OTA update fails on rooted Vodafone One X

Hello guys,
I have a HTC One X from Vodafone, rooted, unlocked, stock rom, custom recovery, and today (FINALLY ) I received the OTA update to Jelly Bean.
I downloaded it and tried to install it using the custom recovery but it was failing on some assert. I guessed that it was because of the recovery so I flashed back the stock recovery and tried to install; fail again.
Went online and found the directory for the update log and saw an entry saying that there was a problem trying to verify the stock Dropbox apk that comes with the phone and that is placed on /system/apps. I read somewhere that if you modify something on the stock apks the OTA would fail, and unfortunatelly I did, I flashed the Galaxy S3 Dropbox apk on my phone, but that's not the problem, the problem is that I deleted the flashed Dropbox and the stock Dropbox from /system/apps without knowing it and the OTA is still failing.
My guess is that if I can flash the stock Dropbox apk to /system/apps, the OTA will try to verify it and will succeed, and therefore I'll have finally Jelly Bean on my branded device (as I said, is just a guess) so if someone could please send me the stock Dropbox apk, the one located in /system/apps as well as any other file located there that could possibly be related to Dropbox app, it will be very very appreciated.
If you guys think that I'm missing something here and even after flashing the stock Dropbox apk the OTA will still fail for some karma related reasons, please let me know and help me out.
If you need any other info from my phone let me know too.
If you need the .zip file with the official update from Vodafone I have it too.
Thanks in advance.

TO update OTA you SHOULD HAVE ONLY stock recovery and STOCK boot.img(kernel) ..and this way everything will be ok.

Well yes I have stock recovery (replaced the custom recovery yesterday) and stock kernel, I haven't changed the kernel yet, and according to the log the problem is with Dropbox. I'll try to find it and paste it here so you guys can see it.
Thanks.

Just flash the RUU, update OTA and reroot.

Alright, will do and I'll let you know how it goes. Thanks

I have exactly the same problem and I dont know what to do!
I'd like to just flash the Android Revolution HD JB ROM but im scared of bricking my phone and there is no easy guide to accomplish this - the guides ive seen on youtube are for other ROMS...
So, now that JB is out OTA for my stock ROM I want to update to it but I get stuck...
All ive done is unlock my bootloader - Ive never even flashed a custom ROM!
Wish I'd never done it now...way too complex

I think they're right, if I hadn't touched the system apps then I think the update would work, having only unlocked and rooted. Right after you try to install the update, go to /cache/recovery/ and check the logs for any clues on why the update is failing.
I'll try flashing the RUU for my phone, then applying the OTA and the rerooting as suggested, maybe you should try the same.

And rule number 1 after flashing cwm custom recovery is
always do a nandroid backup from the stock rom ! Now you know why its important.so when you go to JB and start rooting and running custom roms.....do the nandroid backup to avoid these situations !

I unlocked the bootloader (HTCDev)
I flashed CWR...
That was it (I am running a different launcher but that makes no different right??)
How do I get the RUU for Vodafone UK? Is that the stock ROM? Sorry, I am not very good with this stuff...I was okay at rooting my Desire HD but this is another level

You need to flash the stock recovery !
Do this command
Fastboot getvar version-main
If a number pops up starting with 2.17 you need to flash back this recovery

And yes you did more than just unlock the bootloader, be specific .... it's necessary for this phone otherwise it gets confusing !

But I still have the stock ROM. I never flashed a custom ROM. I wanted to flash a JB rom, thats why i rooted...then I discovered that my CID was not capable of getting a JB ROM so I just left it rooted but on stock voda ROM...

Doesn't matter .... Did u read my post above yours ....
Last time .....
You need stock rom,stock kernel, STOCK RECOVERY....not the custom cwm recovery. That's why the update fails. :thumbup:

Yes, I thought i flashed stock before but am about to confirm

The goal after unlocking the bootloader is to flash a custom recovery to flash different roms.....therefore i doubt u flashed the stock recovery.....unlocking the bootloader and flashing a stock recovery doesn't make sense

Yes, sorry - i did read it and it did say 2.17xxx...I downloaded the recovery you pointed me to but expect i need to re-unlock the bootloader. (I re-locked it before thinking that was causing the issue...)

There is a good chance you are correct. The file in my fastboot folder said recovery and I assumed it was what I was after but it may have been connected to something that I was told to download in the unlocking process (I followed a guide on Youtube by a chap called cursed4eva)
I'm reunlocking the bootloader now because I got an error wh3n i tried to flash that recovery img. "writing 'recovery'... FAILED (remote: not allowed)"
---------- Post added at 01:24 AM ---------- Previous post was at 12:34 AM ----------
Okay - so I
1/ reunlocked the bootloader which basically wiped the phone back to its initialt state all be it with an unlocked bootloader.
2/ once again completed the OTA download of Vodafone Jellybean for the One X
3/ flashed the 2.17 recovery img that Marcel provided
4/ tried to update
5/ am currently looking at a download / progress bar! (YESSSS!)
6/ am hoping this works!
Thanks a lot Marcel. I very much appreciate your patience!

I already have the RUU for my phone, and I was planning to follow this tutorial: http://forum.xda-developers.com/showthread.php?t=1660807
But I was thinking, what if I flash only the system.img instead of all the 3 files? I already have the stock recovery (the one you provided) and I've never changed the boot.img so I still have the stock one.
What about if I flash the system.img only, and then try the OTA update? Do you think that would work?
Thanks for the help.

Yes you can try that, the phone is already wiped with unlocking the bootloader, i never tried it. But in logical terms it is possible yes. If doesn't work you can always run the complete ruu !

That's weird, I'm getting error 00000006 when trying to flash the system.img.
Reading on other posts that's related to the size of the file, which is around 1 GB. If I can't flash the system.img I think I wont be able to run the entire RUU either.
Do you know a way to bypass this error?

[Q] SGH-I747 Update Issues to 4.4.2

I'm trying to help out a friend and update his Galaxy S3 SGH-I747. He originally had cyanogenmod installed but he restored his phone back to stock and flashed a stock recovery back to the phone. When he tries to do an OTA updated it downloads but fails to install? His current android version is 4.1.1 but his baseband is I747UCUFNE4 which if im not mistaken is for android 4.4.2 what would be the easiest way to get his phone updated to the stock 4.4.2 software?

Thanks, I had found the last link (....2789917) by doing a Google search (i.e., searching within the forum was less successful).

Hey bmoliver and BWolf56,
I am in the same boat as your friend where my baseband (bootloader) version is I747UCUFNE4 but the software version is stuck at 4.1.1. AT&T is identifying a OTA update, downloading but the update is failing.
I tried the method described in http://forum.xda-developers.com/showthread.php?t=2789917. But when I am trying to flash MJB bootloader, it is failing. I read elsewhere in this forum that downgrading from UCU to MJB is not really advisable.
I am stuck in 4.1.1 and my phone is half functional at the moment with the camera, nfc, bluetooth not functional :crying:.
Was your friend able to get this resolved bmoliver?
I tried searching for a I747UCUFNE4 md5 file that I can flash using odin (just a hope that it might work) but could not find.
It would be great if one of you can point me to it.
PS: I am a complete newbie to this entire thing and so far from what I read, my phone is probably soft-bricked and am hoping that someone would guide and help me get out of this.
EDIT: One more thing that I observed is when I am trying flash something in the download mode, I get the error and "sw rev check fail fused 3 binary 0" and it fails
Thanks,
CJ

You don't want to downgrade bootloaders, that will brick your phone.
You'll have to flash NE4 with Odin (or a NE4 custom ROM through custom recovery) to get your baseband and software matching.
The thread you linked should work if you follow it to a T. If something doesn't work, let us know and be specific about what happened.

Thanks for the info BWolf56,
Sorry for asking a trivial question (just getting accustomed to the lingo used here) .
When you say I should follow it to a T, are you just referring to follow all the steps.
I tried two things
1. follow each step, but failed at step 3 since I was trying to downgrade my bootloader.
2. I jumped from step 2 to step 6 and tried to flash 4.4.2OTA.zip in recovery mode but that also failed. I dont remember the exact error I got, I can try it again to give you more details if you think it is safe.
Thanks

If you jumped to #6, you didn't flash a custom recovery, which you need to flash the OTA.

I did install TWRP 2.6.3.1 which I am guessing is the custom recovery (as part of step 2) and then I tried to flash the OTA. Am I missing something here?

Sounds like you'll have to use Odin to flash Stock.
Your build.prop is most likely borked (or has been changed to something it's not). d2u is not a variant of the S3, nor does it exist.

Thanks a ton for helping me identify the problem.
I just have to look if a stock file to flash using odin is out there somewhere.
I will post in http://forum.xda-developers.com/showthread.php?t=2789917 to see if enewman17 or someone from the community have a tar or md5 file that I can use.
I will try that and update on how it goes.

They only have MJ2, LK3, LG1, LEM versions, no MJB either.

There isn't a NE4 stock for Odin. I just noticed the post hasn't been updated in a while.
I though I could find it on Sammobile.com but they have LK3 as their latest too.

Since you somehow have the 4.4.2 modem, you can not flash anything older than the 4.4.2 firmware. Currently there is nothing that you can flash to fix this. Normally, I would say to flash an older modem, but if Odin is seeing it as already updated to 4.4.2 (SWREV 3), and the only thing you have that is 4.4.2 is the modem, flashing anything older will likely hard brick.
You need either the full stock firmware, which there is not one, Thanks AT&T!, or a recovery flashable firmware for 4.4.2. Enewman17 has this, but it will not work for you because of how the modem is flashed. For some reason, he has it patching the 4.3 modem rather than including the full updated one like with the other partitions. If someone makes the same thing, but with the already updated modem, you could probably flash that. No guarantees though. Running 4.1.1 firmware/bootloaders with a 4.4.2 modem is a scenario which is highly unpredictable, so anything you try to flash might cause more problems, we just don't know.
I've PM'd enewman17 to ask if there was a specific reason he updated the modem the way he did. If there is not an issue doing it like i mentioned someone can try to make a new package like that for you to try.

Thanks Doc!
Hopefully enewman17 can come up with a solution for this.
Just an information which I was not able to completely comprehend but maybe pros like you or Bwolf56 will be able to.
I opened Kies and this is what it says.
Firmware information
This is the latest firmware.
Current firmware version: PDA:LK3 / PHONE:NE4 / CSC:LK3 (ATT)
Any thoughts on how do I get the PDA and CSC updated (not even sure what exactly they are)
Thanks

Ok, enewman17 just put this together if you want to try it. This includes the full NE4 stock firmware minus system, kernel, cache and recovery.
So flashing it will preserve your current Rom, kernel and recovery, but will otherwise fully update your base firmware/bootloaders to NE4.
This should be perfectly safe to use, but seeing as it is untested, I cannot make any guarantees that it won't make things worse. (I wouldn't post it if I thought it would, but there is always the possibility)
Flash from custom recovery such as TWRP.

If you want to fully update your system (rom) to stock NE4, enewman17 has a thread in the development section with stock rooms you can flash via recovery after you update your firmware posted above.

My P6 is....messed and disorganized...need to downgrade...

Hey guys. Im really new to this scene and i need some help.
now currently i have kitkat 4.4.2 and im trying to downgrade to 4.2 the latest stable version for huawei.
i have the update.app ready and its in dload folder already. but when i try to downgrade it says its in lock state or something....
when i try to root it says its failing....thats with vroot and eroot.
can someone please help me with this. i just want the latest stable firmware on it and enjoy google play after a year of hell.

hm..
eroot and vroot are sometimes not proper working..
twrp 2700 and 2800 are the best way to get root (98% sure)..
first of all you need to get all the device drivers on your pc (notnonly the hisuite drivers..search for lesscro on this forum..there you should find drivers concerning huawei)..
then you need adb&fastboot (different packages and names..searchengines should find it )..
then use the search for how to flash twrp..and when you are searching, the next search should be how to downgrade from 4.4.2 to 4.2.x
i think this helps you the best..

Hey so i was able to root it with root genius. now whats the next step? sorry if im annoying but i want to make ABSOLUTELY SURE i dont screw this up.

alright so i got twrp in and its been flashed. now the only thing is to downgrade my phone from 4.4.2 to 4.2

ok i cant seem to update the UPDATE.APP. i have it both on my sd card and my phone.
my recovery is back to stock and it fails on VERLIST.
I need help.

CRAP
ok im freakin out now....its hanging at the huawei ascend logo. help.

tried to reloaD boot.img now and it says partition does not exist

Before you go and do anything now, flash stock 4.4 recovery and boot img, after that search the forum for link of a middle step for downgrading to 4.2 and flash that thruogh stock recovery then try to install stock JB.

thanks....
but i still cant mount system and data. where can i get the 4.4 stock? sorry i went through hell today....i dont want any "bad" files...

i fixed the system/data errors. it was wipe > advanced wipe > JUST CLICK system. after that i went to format all data and it removed those errors...
but when i try to install the stock firmware(from huawei) for 4.2 it still says failed
"Error flashing zip '/external_sd/dload/firm.zip"
Updating partition details...Failed

REALLY need an answer here.....

last post for the night....
when i try to fastboot -w update my rom i get the 2 files missing android-info.txt and android-product.txt.
hopefully i get a few responses when i wake up.

Ok since you can actually boot into recovery is a good sign so try to wipe/reset anything you can from there and then try to flash some firmware, if that doesnt go try to flash a custom recovery like twrp and install a custom rom, that would give an idea where is the problem maybe and from there its easier to get back

"Error flashing zip '/external_sd/dload/firm.zip'

you are on twrp or stock recovery? it's not a problem if you don't have os installed.

currently i have twrp on.
would it help a great deal if i just made a video of it?

Update to Android 6 and TWRP

I have installed the TWRP and just wanted to update to Android 6. The problem is, that once the download finishes and the phone reboots, it puts me in the TWRP instead of installing the update. How do I proceed to update my phone to Android 6?

You want to install OTA on TWRP? Not gonna work, find your software number(4.xx.xx.xx) in Settings/about. Then flash stock recovery(numbers must match with software number) and try to apply OTA. You might need clean stock(non-rooted) rom.

I checked my version and it says 4.16.401.13, so I downloaded the stock+recovery+4.16.401.13_M8 and flashed it via adb using "fastboot flash recovery img". When I wanted to install the OTA I got into the recovery and got this: http://imgur.com/FpVk5Sg
Afaik I have the official ROM and just got root access for a few apps back in the days

unexpected contents(i think thats some root binaries etc)...
Anyways, check this thread and download stock twrp nand for your 4.16.401.13 firmware from here, follow the steps carefully, it's easy. http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860

Thank you! Am I seeing that right, that all of my apps and co will be gone afterwards?

Yep, but you can always backup apps(+data of apps) with titanium backup pro and restore later.

Either need to install a stock (never rooted) ROM, of you have the wrong stock recovery.

You haven't posted enough information. Posting that you have the "same problem" isn't helpful, and usually leaves us lacking the specific information needed to help you at all.
Do fastboot getvar all, and post the output (delete IMEI and serial number).
Also, is Bootloader is unlocked?
Is the phone currently on stock ROM? Rooted?
What version TWRP?
