I'm using a UK OP7T if this matters

Bootloader for T-Mobile US rom

Does anybody have the original bootloader for the T-Mobile US rom handy as a sbf file ?
It seems that the update to 6.390 (from 6.190) works only if you have the original bootloader installed. Of course mine is either 2.21 or 2.34 depending upon the day of the week ;-)
If you tell me or point me in the right direction I can pull it from one of my phones.
Hey BizzaBoy, did you get that bootloader. I've been trying to figure out why my Defy is not upgrading and I came up with the same conclusion. I believe I changed the bootloader when I flashed to the CN Froyo. Now, I'm back to my original T-Mobile software but I get an error when I try to update.

No, I didn't try. It seems that you cannot downgrade the bootloader. On the other hand, I'm happy right now with the 3.4.2 T-Mobile Froyo ;-) Guess they (Motorola & T-Mobile) just want to make it painfull for people who every now and then want to try out something new to switch back the phone to it's original state.
Which, or whose ROM did you use?

[Q] Stock Telstra Firmware (R800a)

Hi everyone,
I've been searching madly for this to no avail. Unfortuantely I've been having some random reboot issues with my Play and it's looking like it's hardware based. Restarting several times per day, usually when coming out of screen lock. Tried flashing multiple firmwares, different kernels, wiping out everything with CWM. Still no luck.
I'm about to return the handset to Telstra to see about a repair as it's still under warranty. Problem is, Telstra is anal about having their own stock software still on the handset. I didn't think to make a backup of the stock Telstra firmware before flashing a generic UK ROM (I know, stupid).
Could anyone point me in the direction of a stock Telstra ROM? Preferably FTF?
99 views and nobody has anything?
I'm having this exact same problem. Did you find a solution for it? I've tried heaps of things, but I have no idea what the problem is, however it's really frustrating. Thanks
Could you perhaps send it back to Sony (with a locked bootloader and no root)? If it's a hardware issue they shouldn't have a problem I think.
I don't have a problem but I have also been scouring the net for an FTF or whatever for stock Telstra R800a incase I need to return it. I read that there is an update for R800a on Telstra if you use PC Companion, but we would need a build.prop from original Telstra firmware for it to recognize.... could somebody share it?
I know it might only be an OTA update, but it's worth a try to get original build.prop values from stock and extract the update from PC Companion cache. Please, if anybody on stock Telstra firmware not yet updated in PC Companion could share their build.prop file, it could help.

[Q] Question about warranty and custom ROM

So, i'm tempted to flash Omega or Android HD ROM on my Note 2, but i'm worried about a few things...
I already have the phone rooted, and from what i've understood so far, i can use triangle away to make it look like it was never touched, in case i need to go to warranty (please correct me if what i've said is wrong).
Will i be able to make it look like it's never been flashed/tampered with, if i flash a custom ROM and i have to go to warranty?
Let's say i DO flash a custom ROM like Omega or Android HD and a button isn't working anymore, and it's surely a hardware problem, naturally, i'll have to go to warranty to get it fixed. In this situation, will i be able to flash a stock ROM and fool everyone that it's never been flashed/rooted? And if yes, how? I'd appreciate a description of the whole process.
Hope i've been able to explain myself well enough to get an answer.
Thanks in advance!
You would need to find the stock firmware for your device and then flash it using odin
Sent from my SGH-T889 using xda premium
This is my device's info:
Model number: GT-N7100
Baseband version: N7100BUALI8
Build number: JRO003C.N7100XXALIJ
Is there any way to find out where to get my stock ROM?
Depends what country you from and whether the phone in it's original state was branded to a specific carrier or not.
If you know that then go to www.samfirmware.com and search for your stock firmware
eg: if you're from UK, and your carrier is Vodafone, then you would choose, "United Kingdom (Vodafone)" firmware. etc..
After you download your firmware, then flash with odin, and make sure that the flash counter is "0" using triangle away, and that's it. The process of reflashing a stock firmware to your phone should unroot you automatically if you are rooted.
Yes, my phone was branded and locked to Vodafone, Romania, but i've used GalaxSim to unlock it (YAY!).
I've searched SamFirmware for the ROM that i should have, but there's only one for Romania ( http://www.sammobile.com/firmware/?page=8&view=7110 )
I don't know if this is the one that came with my phone, but i guess it should be ok, right?
Later edit: OMFG, the ROM is 1.3 GB
Even later edit: Damn, HotFile is so slow T_T''

Need to return my phone under warranty, have I got it back to complete stock?

Hey,
My phone is faulty, and I need to return it under warranty. I had unlocked the bootloader and installed custom roms, so I just want to check that I've managed to undo all that, and that at the factory they won't be able to tell that I had it rooted.
The main-version is 3.14.980.27, which I couldn't find an RUU to work with, so I downloaded the Stock Nandroid Backup, flashed the boot.img it contained, restored the stock nandroid backup, flashed the stock recovery, relocked my bootloader and deleted eveything from the internal sd card. Having done all this am I ok to send it back for warranty?
The fault is nothing to do with rooting it, but just a little worried that if they find any evidence I rooted it, then they will refuse to fix it and I'll be out $600.
Thanks in advance for all advice.

There's plenty of threads about going back to stock
You are as stock as you can be ..... they can always tell by the relocked bootloader that its been unlocked ..... so its sending it in and hope for the best.
This is somewhat related. I need to send my phone under warranty due to the dreadful green tint camera problem that arises when some people update to jelly bean, what are the chances of them repairing my phone even though I'm rooted and have a custom ROM? Surely they must know this is not a problem caused by rooting or flashing since it occurs on the stock ROMs as well, right?

Trying to update to 4.2.2 but get an error message on philztouch

Please see attachment for error message.
Does anyone know how I can update to 4.2.2 (stock version) without getting this message?
You need to have the stock recovery installed as well as not having any root from memory.
I tried to sell the phone but it was knocked back for being rooted. What's the best way to unroot? Is it easy to get the phone back to factory condition?

Not possible. You can flash an ruu if you can find it. Or a stock based rom.
But relocking the bootloader will display tampered or relocked or something similar.
Its not possible to rewrite this flag to original state without having s-off.
The trace of the phone being or have been modified is permanent.
I have on my htc one x custom rom and cwm, can someone post a link to fastory 4.2.2. with sence 5.0, and hot to get it back to original state?
I would appreciate it. thank you cheeres...
