Like many of you I haved rooted, unlocked with FreeGee and installed many custom ROMs on my LG Optimus G.
Now I decided to go back to STOCK ROM, I followed this GUIDE to flash KDZ, everything worked OK, phone works like it has to.
So if everything works what are the problems, well ... I have some questions for you:
1. Many of you are writing in the forum that after flashing the KDZ the phone will revert back completly to stock. Will it revert bootloader back to stock too?
2. If the answer of above question is that it will revert back to stock, then in this forum someone says that bluetooth gets its MAC adress from bootloader. Why my bluetooth MAC still begins with 41:4E ? Is this one of the compromises when you unlock the bootloader?
3. Is it possible that in flashing KDZ guide I did something that will not flash the bootloader?
4. Is there a way to fix bluetooth MAC adress?
Thanks in advance for your answers.

hi all,
i did a bad root and bad flash( without EFS backup ) ,,
altough ive flashed a stock rom via ODIN, i get no signals ( and blutooth ) and NO IMEI
EFS is messed up basically
as i said above, i made no EFS back up ,, so is there any way i can restore it another way to get my phone working ! ?
regards
firstly, did you flash the proper rom for your device? as the signal and such look modem related to me.
you can find flashable modems (gt-n7105) in the development section: http://forum.xda-developers.com/showthread.php?t=2031575
about the IMEI, i don't think there's any way you can recover it if you don't have an EFS backup somewhere. Reckon the only thing doable would be flash the stock rom root it, use triangle away to reset the counters and flash back the stock rom so you have the device completely stock again.
afterwards claim waranty and just make up a story about how suddenly your phone stopped working completely. and the only thing it currently is, is an overpriced tablet (do make sure you have the correct stock rom though, as when you flash one for AT&T on a T-Moble, or one of those on a normal international unbranded version they will notice )
don't exactly know what model you have, but getting root on my n7105 was one of the easiest things i ever did to a phone, with cf-autoroot and odin it worked like a charm within seconds.

phone is used, no warranty

mmm,
no clue how long the waranty is with samsung,
but i found this page where you can check if you still have waranty http://www.samsunguniverse.com/samtools/samwarranty/
simply enter the digits of your serial number and if it works properly you'll know if you still have warantywithin seconds
will flashing back to stock thru odin be of any use ?
don't know you can always try though, but i don't think it'll help much. as IMEI and such are completely device specific i don't think flashing a stock rom would help in getting it back. as the rom is more aimed at a series of devices.
the stock rom option is mostly due to waranty reasons, having a custom rom and not having reset the flash counter would mean they can instantly see you messed up your own device.
resetting flash counter + flashing back stock rom, they won't really notice you where messing around with stuff yourself just play dumb, did that a few times with my tablet as well after i messed things up on it
Several months ago I purchased the nexus 7 2013 wifi version. In my tiredness after a long day I unlocked, rooted then flashed a custom rom (aokp) my build numbers is KVT49L instead of KVT49H. I must have flashed the LTE version in error.
I'm trying to upgrade from 4.4.2 to 4.4.4. Wugfresh toolkit doesn't work, also unfathomables tool won't work either.
I have been rooting, swapping kernels, unlocking bootloaders and flashing custom since the Droid x days.
I assume I need to use ADB? I am having a hard time finding specific instructions on how to complete this minor upgrade to 4.4.4. In afraid to try anything being on the build for a different version of my device.
any suggestions are appreciated.
I apologize in advance if I left out any critical info regarding my situation.
Edit:
Also are the tool kits not working because I'm on the incorrect build?
K... so, does anyone have any thoughts about just flashing KVT49H rom over what I have?

Why isn't the toolkit working with flash stock and unroot? You should be able to select the option that says it is in a boot loop... And for current version, you can select anything you want - that is what it will flash when you do the flash stock and unroot.
If that doesn't work, where specifically does it fail?

It goes into bootloader mode and does not come out. Toolkits worked fine on N7 v1. I am attempting to un root and revert to stock.

Toolkit works on v2 as well. When you do the flash stock and unroot, you have to select the option that says your phone is soft bricked.
If that doesn't work, when you are in the bootloader, are you at least able to use the volume buttons and power to select recovery?
Thanks Mike, I'm going to try that

Soft brick option did the trick!! I was also able to restore to KOT49H. Thanks my friend
Hi guys, I've been reading a lot of different threads, but have gotten myself confused. Its been a long time since I done flashing of software, and things are completely changed since then.
Anyway,I currently have the z5 premium which was purchased in o2, however I have now moved to ee and would like the WiFi calling feature. My handset hasn't been rooted or nor can the bootloader be unlocked. Can I still download stock ee firmware and install it without any problems.
I find most branded firmware to be buggy in some way.
there is a tutorial for backing up your TA partition ( the bit that keeps your DRM keys)
https://forum.xda-developers.com/crossdevice-dev/sony/iovyroot-temp-root-tool-t3349597
and a tutorial for unlocking your bootloader, and compiling a patched Stock Kernel. from there, you will be able to install any of our great Custom roms.
https://forum.xda-developers.com/xp...oot-automatic-repack-stock-kernel-dm-t3301605
If you decide instead to keep your phone locked. you should still be able to flash a stock rom using the FTF and the flash tool. you should still backup all your data, photo's documents etc before doing anything at all with your phone.
and always try to start any new flash completely clean. and build up from there, instead of trying to retain your data, or restoring your apps.
If you want more help with backing up and rooting / unlocking your bootloader just ask. but post the exact model version of your device. as the z5p has 4 different models.
Thanks for the reply Patrick, I got all sorted. Unfortunately the bootloader can't be unlocked on my handset, so can't use custom ROMS. However, I was able to use Flashtool and XperiFirm to download EE's branded firmware, and now I have the WiFi calling feature. Thanks for your help.
Hi guys,
I have a problem I need some advice for. A year ago, I purchased my Amami for the purpose of GPS-navigation on my bicycle. It always worked fine and I was able to charge it with my dynohub without any issues. The charging is giving me a headache now though, and all troubleshooting points at the phone being the problem.
Now, a couple months ago I decided to ditch 4.4 and go for a custom ROM (I've tried Oreo and Pie) which worked fine, but the phone doesn't charge as well as it used to on my bike. I'd like to go back to stock to see if that's what is causing the issue and used the Xperia Flashtool to revert to a stock image, but the ones that used to work on the phone now give me bootloops after I've flashed TWRP and ResurrectionRemix and Lineage OS.
Is there anything I need to know before I flash a stock firmware with the tool? Any input would be appreciated.
Sounds like to have not updated to Lolipop and therefore you do not have real recovery. Is your bootloader unlocked? Then you can try EMMA to update to Lollipop.

My bootloader is unlocked, I have TWRP installed and am currently running Lineage OS (Android 8). It doesn't matter if I flash Sony's original Kitkat or Lollipop; both will have bootloops. No offense, but I'm not sure you understood my original post: I'd like to go back to an old stock ROM, because 4.4 is the one that I'm sure have me no trouble with charging on my bike.
Proper BL relock:

If you use twrp in fotakernel partition maybe necassary to write back original fotakernel.sin (inside stock.ftf) before relock with flashtool. Remember! After relock with flastool the new BL unlock key here: DEVICESERIAL \ unlock.txt
Hello to all,
I just wanted to help u all who want ot go back to stock rom without haste at all. i just rolled bask form custom to stock without a problem of any kind.
i need to download this: Lenovo make roll back tool
and install it.
run program and go to Flash tab, than go to rescue.
next select brand and model of your device.
Wait till download ROM from their servers and follow instructions they provided.
I think that u can flash bricked models too if your computer recognized it.
i didnt lock my bootloader before i did flashing with this tool and i didnt have any problems with that. i am using single sim XT1771 model.
that does not work for hard brick
