Hi all,
I received my Nexus with 4.0.4 and after OTA update (4.1 JB) I had the following problem;
1) settings->mobile networks says (no sim)
2) *#60* says IMEI null/null
3) broadband version says 'unknown'.(device was not rooted at that time).
I tried several things to fix it by no luck at all. Could you please help me with the below questions? I searched a lot but no clear answer.
1) Does rooting void warranty? (I used Nexus Root Toolkit for rooting)
2) I used Nexus Root Toolkit to flash stock + lock the Galaxy Nexus. Can Samsung detect whether the device is rooted or not in the service? Does Nexus Root Toolkit's flash stock function wipes the data&cache and everything totally? (By the way it installed 4.1.1 as stock not 4.0.4 that I had when I received the device)
I will apreciate if you have any clear answers as I could not even use my phone for 1 day because of that official OTA update. Rooting is less risky than OTA I guess.
Thanks,
unroot, relock if you havent already, return the device.

When I press power + volume up&down bootloader menu appears. I can select to restart boot loader or recovery mode or shut dwon via that menu.
is it normal to have that on an unrooted phone? I already performed flash stock + lock operations.

This is normal as every Android phone has a recovery and a bootloader; a lot of people prefer an alternative to the stock recovery and usually will unlock a bootloader to do so and we need these things in the first place to get more creative with our devices .

Hi,
I have the same problem even I do not have a SIM Card installed on the phone.
I checked the status without a SIM Card and IMEI/Baseband still seem as UNKNOWN.

I recently purchased a R800 from someone on Craigslist. The phone is already rooted, permanantly I think since it is rooted after doing a factory restore. It is not sim locked, I believe its factory unlocked.
I tried to do the OTA update, which downloads, but fails to install. It appears to get about 3/4 of the way done, reboots and gives me an "update failed" message.
I wanted to unlock the boot loader, I got the unlock key from SE. I must of tried 10 times to get the phone to boot into fastboot mode, it NEVER does it. It simply boots up normally. I even got an app that makes it easy to reboot into restore or fastboot modes (just click an option and it reboots), however just like before the phone simply reboots normally. I even did a factory restore prior to trying the update... no go.
Should I try to remove the root access? Is this what is giving me all the problems. I was able to successfully install root explorer and titanium backup and both of those programs worked fine.

Edit: Title should be "Can not OTA or enter fastboot mode, root problems?"
Is your phone sim locked? Sim locked phones need to be unlocked before able to unlock bootloader or fast load. After you unlock bootloader make sure you never ota update.

Your phone has a locked bootloader and a factory lockout on fastboot.
Best advice to you is flash the r800a world generic 2.3.2 root it with gingerbreak then ota update. Use a program called wontanserver as its super easy.
Dont get anyone to remove your factory locks on fastboot until you read tons of threads on these fourms from the last couple months.
Ok, lets see....

My phone is the R800a. It was my understanding that this phone was never locked (factory unlocked). It came in an official Sony Ericsson box and has no carrier branding on it what-so-ever. It was not purchased through a carrier. It does have a weird stock data APN called "Telekila"?!?!?

Doesn't wontonserver require credits to run? How expensive does this get?
I didn't know the phone could have a factory lock on the bootloader. I did go to the SE website where you get the unlock key and it was successful in giving me a key... Well I shouldn't exactly say "successful", it did give me a key code to use if and when I can unlock the bootloader, weather or not that code is actually legit remains to be seen. I'm a bit skeptical now since you said the phone is bootloader locked from the factory. I though SE was allowing their phones to be unlocked. I recently unlocked my Motorola Atrix and was expecting to do the same with this phone.
Thank you guys for the advice. I love this phone so far but I can't wait to get a custom rom on it
It uses credits but they are free.
There are currently 2 gentlemen on these forums that can remove your fastboot locks and unlock your bootloader.
Have a look for thier threads on this matter
I would like to have this done now, so gentlemen, whomever is able to do this please message me and we can work something out. Im dieing to get a new rom on this awesome phone/game console.

I flashed the r800a world generic 2.3.2 rooted it with gingerbreak then ota updated.I get the same thing as DMpire , reboots and gives me an "update failed" message.
Is this because I removed some of the stock apps that came on the phone after it was rooted? Anyone know about this?
Does it matter if the SD card is mounted or not?
Removing stock apps then trying to ota isnt going to happen. Reflash, root, ota, then remove your stock apps
Is there any easy way to do this? can I reflash it as it has a locked bootloader, or do I have to get the bootloader unlocked?

Hey all.
My Gnex has developed a charging problem whereby it thinks it's charging when it's not and wont always charge when it's plugged in.
I took it back to Three (my uk network) and they were aware that I was keen on rooting it. The guy asked me if I rooted it and I said that it 'currently was not rooted' as I had unrooted and stuck the stock ICS software on it in the morning.
He told me that 'Samsung would know if it's been rooted before and would charge me for the part needed to repair the device', so I took it home again to find out more.
It turns out that there is a Flash Counter on the GSII, III and the Note which I guess counts how many times you've flashed a rom and so if it doesn't match Samsungs records they will charge me, but I can't find any info about the Gnex.
So does anyone know if my Galaxy Nexus has a flash counter?
Thanks
No.
You're fine.

Flash counter no. However they can tell if you've potentially done anything by the status of your bootloader (locked or unlocked). Unlocking the bootloader is meant to void your warranty anyway.
If it is unlocked, just lock it again and you'll be fine.

Okey they know you've done anything if you send the phone like that, but if you reinstall official google rom + wipe data + wipe cache + wipe dalvik cache + lock bootloader, they wouldn't know would they?
I think that is what the the original poster means.
As topic says, will I still receive OTAs if I unlock my phone through htcdev?
Yes. If you ONLY just unlocked it and did NOT make any other changes you will receive updates !
If you did make changes, you could relock the boot loader and run the RUU to bring your phone completely back to stock.

Ok, thanks. I'm just about to unlock my phone, when I hit this on the htcdev page
On your phone you will now see the disclaimer. Please read this carefully as this action may void your warranty. Use the Volume buttons to highlight your choice, and the Power button to make your selection. If you select Yes, your phone will be reset to its’ factory default settings, and your bootloader will be unlocked. If you select No, your phone will reboot and no modifications will have been made.

Does the process actually factory reset the phone or just the boatloader. (I want to keep my stuff...)
When you unlock bootloader it will do a full factory reset, you will lose everything
Only Contacts/Messages and stuff
NOthing will be wiped from ur 25gb SD card but yeah ur internal Memory will be wiped!
I have a galaxy A50 and recently rooted it and installed twrp recovery and then again flashed the stock image.Now when I boot the phone it shows that ugly bootloader warning.Can I lock the bootloader now?
And also
Will I receive updates?, as the phone status is official.
Im not sure but i think you lost OTA updates even after relocking the bootloader since your knox status is tripped but thats not a big issue since you can still use odin to update your phone.
to remove the bootloader warning you have 2 options:
1- Relock the bootloader since you have stock official rom. To do that you need to turn off the phone, hold V+ and V- and connect the usb cable to your pc, the phone will enter a "special" download mode, long press V+ to relock your bootloader, the phone will factory reset with locked bootloader .
2- Use this method to just remove the warning and keep your phone bootloader unlocked with official or rooted/modded firmware.
Hello everyone.
I recently bought a Samsung Galaxy S22 SM-S901B/DS 256MB in the UK. I'm trying to unlock the bootloader to get root with Magisk.
First, I updated the operating system to the latest version available. After that I managed to toggle the OEM unlocking in the Developer Options but when I restart to Download mode I don't get the option to long press the volume up key to finish the process. There's a line that says "OEM UNLOCK: ON(U1)". That very line read "OEM UNLOCK: ON(L1)" before I toggled the option in the Developer section.
I tried to install an AP file modified by Magisk with Odin 3.14 but at the end of the process I get the error "Custom binary (VBMETA) blocked due to remaining installment balance" and I have to flash the original OS from scratch to be able to use the phone again.
Could anyone please help me here?
AFAIK, currently, there is no way!

That's what I get at step 4. No matter how long I press Vol Up + Vol Down, i can't see the option to unlock BL.
Looks like some restrictions for unlocking are enforced by the region specific Firmware.
You can try to flash alternate stock firmware from different region (probably Asia).
This could hard brick your device. So, it is your choice to proceed or stick with current Working Firmware without root.

It might be that you are already bootloader unlocked

Thanks for your reply.
Do you know of any specific firmware that allows to unlock the bootloader for this specific model?
Can I cross flash a firmware from a different region?
Can I downgrade my firmware?

2. I have not tested cross flashing Samsung Firmware so I cannot give any feedback.
3. Downgrade from A12 to A11 will certainly fail. I have tested this just last month.
> "Custom binary (VBMETA) blocked due to remaining installment balance"
That's seems like another layer of protection by Samsung, so that you first pay off the loan for the phone, and then you can root it.
hi @chinchulin01 ,
is there any news for the root?
At what point do you get stuck?

For my phone model they use a EVR firm, so I downloaded SamFw_FRP_Tool_v3.0 and changed the CSC of the phone to EVR. I downloaded the most recent EVR firm and I tried to flash it with Odin 3.14.1 modified, but I keep getting a Fail message.
No idea what to do next.
