Hello everybody!
Last night I say the new SlimRom post and decided to try it, I have to say that I didn't know if my bootloader was unlocked or locked, so I tried to install Phils Touch Recovery that was suggested. It didn't work, after that tried the CMW for locked bootloaders, it didn't work either. Just got the "security error" message when trying to enter recovery mode. After that I say the Unlocked Bootloader post and decided to give it a try, everything was fine until the phone restarted, after that it didn't boot, it would stay with a black screen vibrating. I decided to use the LG flash tool 2014 that a user named yunior suggested to use (saw this at the Unlocked Bootloader post) and it runned fined, but after that, the phone wont even vibrate neither get the black screen. When I read phone information from LG FT2014 I get this
IMEI Empty.
IMEI Auth fail....Please check IMEI value
Phone Mode :Normal
Phone Model :
Server Model :
Buyer :
Phone Version :
Server version :
**Phone sub version lenght is more than 2 digit
**Server version is empty
please check IMEI or S/W file status in CSMG
I would really appreciate your help! Really need my phone back:fingers-crossed:
Thank you!

SO, i followed a guide the other day to get lollipop on my wind huawei mate 2.
but now i want to switch back to the original android that came with the phone because i want to unlock the phone, and the lollipop one on the guide i followed doesnt show the unlock code entry screen when i put in a different sim card.
the issue i am having?
when i flash the stock recovery file that i found on here, that boots fine, then when i try to install B128 wind firmware, it says a bunch of error codes along the size of
oemsbl write failed something or other then it also said update_vendor.app install failed - invalid package
i'm hoping someone can help me because my phone will not go past the huawei logo at this point.
i do have access to fastboot mode though thank god.
if anyone can help me with the proper files to download and such that would be great!

With NO stock backup i doubt it.
So basicaly I was being lazy and in a rush. I had done something like this before on much older phone(s) with no issues...
I backed up my working LG G5 in TWRP all partitions. I brought exactly the same model for my wife and wanted to restore my backup to that phone (I have made many customisations on my rom and didnt want to have to manually do it all again for her)
However after unlocking the bootloader, flashing TWRP and installing new base rom (all went fine) I then went to restore my old backup onto this new phone, stupidly I ticked all partitions to restore. I have a feeling that I should have only done the larger partitions. Once I rebooted I got the "cant be trusted" message, I reflashed in UPPERCUT but then the phone booted and then had secureboot enabled. I hit the wrong password (as there was none) 30 times which then forced a format. Now the phone boots fine and works 100% BUT...BUT....
I now can no longer unlock the bootloader as I think its trying to use MY phones bootloader (as its unlock.img says its the wrong one, I have tried both MY phones original unlock.img and my wifes new phones unlock.img but both dont work) I cannot relock the bootloader as it says its already locked... this also now means that through LG official software I cannot recover the phone. Only UPPERCUT can see the phone. I can get to download mode and fastboot.
Also the phones IMEI now says 0, this worried me however her SIM card is working 100% fine (I guess that the IMEI
is cached somewhere, but im worried that if I use some cleaning tools it may scrub it and then she will have no network access)
So basicaly if her phone starts to play up (or I want to upgrade it to Oreo / Lineage at a later date) can anyone offer me advice on how to...
A: Fix / Restore the bootloader (I dont mean recovery) Im confused as to if this is stored on a chip or can be reflashed from the kdz firmware images.
B: Resore the IMEI (I have it written down) incase we get any network issues in the future. Can it be resored or regenerated without some fancy hardware, ie only through software.
C: I dont have Root or TWRP access it seems, any way of Getting Magisk or Super SU on a phone without bootloader unlock, root access or TWRP?
I have had many years experience and never bricked a phone but almost did this time.
I decided to post a solution here, because it was one of the first Google results when I was looking for some help.
Long story short, I did exactly same mistake of restoring all partitions, including the EFS, between two same LG devices. Turns out it messes with IMEI, which is a big no no and phone locks. Now you can't unlock the device again, because there is no IMEI to use in unlocking. Also no flashing or erasing anymore, because it just fails.
So the IMEI needs to be restored first.
My phone was in a bootloop constantly showing the "cant be trusted" message, but I managed to fix that using LGUP. Apparently not all partitions are locked, because trying to flash the same system with LGUP fixed the bootloop, but failed to flash clean system and the data that TWRP flashed was still there. Trying to restore system to factory settings also fails, but it doesn't matter.
Fortunately I was able boot the system, which made fixing it easier than you'd expect:
1. Fixing the IMEI from booted system (no root or unlocking needed):
- Access the hidden menu on your device by dialing a proper number. For LG G5 H850 it is *#546368#*#850#
Where 850 in the last part is your phone model. The number will vary for different models.
- Go to SVC Menu -> CRCWIZARD Test
- Switch tab to Auto MID
- Here you can enter your new IMEI and WiFi and BT MAC addresses, or you can just generate it.
You can also use the generate option for all values and then manually change only the IMEI for the original one.
- Press MID Write button and reboot your device.
- That's it. IMEI issue should be fixed now.
2. Now that you restored your original IMEI, you can again unlock your device using the same unlock.bin file that you used to unlock bootloader the first time.
Voila. From now on the device is again unlocked and you can just go back to flashing whatever you need.
I have an European version of LG V10 H960a, Android 6.0. The official LG website provides an instruction how to generate an boot image for this phone with adb and fastboot. I did everything according to their instructions, I generated a device ID,I put both dev ID and IMEI to proper boxes in their website and after clicking "Confirm" each single time I received a message "Device ID is unmatched. Please check device ID...". I have been trying to repeat whole process by connecting via VPN from Polish IP number, because phone was bought in Poland while currently I am in UK. I created new account, I did everything accordingly to their instructions and still same. I have tried to contact with LG via email address given on their unlocking website [email protected] but they even did not bother to answer my emails and I tried to contact them TWICE! If someone have an idea how to unlock bootloader please help.

Mu bootloader is unlocked BUT it does not have a write command... Its been removed and I cannot write a file to the rom through ADB. It says its successful but nothing writes to the rom. There is NOTHING I can do to root it short of removing the device and copying an image of the boot partition to it through Octopus or something like that. I'm pretty good with the V10 (H901) and have rooted several over a couple of years in succession until it dies with the usual bootloop hardware issue on the motherboard. I'm certain it's the most unreliable smartphone out there. I'm at the point of throwing the damn thing against a wall and being DONE with ALL of LG products forever.
I buy a phone from Ebay, i flashed the phone with wrong rom's in Smart Phone Flash Tool. then i flashed the phone i check the Bootloader off. so i don't flash the preloader.
I searched around and i found close to the phone and it was MT6735M without error in Smart Phone Flash Tool. But the phone still does not boot up, without success.
I asked on this forum i another topics, he help me to get preloader.bin out of my phone, now i have the preloader.bin.
What the problem i can't found the right rom right now.
The name is: (GSM UNLOCKED 4G LTE 6.29" Waterdrop Screen Smart Phone Android 9 Fingerprint ID) from Ebay
i get confused:
Before i flash the Phone it says (MT6595)
I got booted it op in mode: and it says (MT6735)
The buyer says (MT6575)
WwR MTK says: CPU type: (MT6752)
Can some one help me with the right rom? i hope you also not get confused as i am. Tell me if you need more info about the topic.
hi all,
I have Samsung SM-G935W8 (in Canada), bought used from someone. recently, try to play with android, and realized the phone PDA was G935UUEU4BRD1, and model was SM-G935U which is different from the model that showing on back cover. think the guy flashed a different rom for this phone.
couple days ago, I did hard factory reset for no reason, and get google account locked. then search online and learning how to fix it. seems like need to flash combination rom --> use tool bypass frp --> flash official rom to solve this issues.
i downloaded many combination firmware and all failed on odin flash. until i use one that allowed me to flash and success to open the phone as Factory Binary. But, I noticed the phone model changed to SM-G935A, which is AT&T firmware. the android version is 6.0.1, when I try to run program to do FRP bypass, no luck, think that because I can't turn on OEM- Unlock option(can't find it on developer option tough)? or bootloader locked?
now, I can only flash official rom that from AT&T, and android 8 that I can find it. if the phone can be fixed FRP issues, model change to G935A is fine, I dont care that model, I dont use the phone for call, only for wifi and camera. and maybe later can play flash to other model of ROM. not sure if possible.
current, the working combination rom I flashed is PDA : G935UUCUBATA1
ADB FRP to bypass FRP (not working)
and flashed to AT&T rom PDA: G935AUCUBCTB1_G935AATTBCTB1_8.0.0
FRP still not bypassed, and stuck on google account validation screen. any advice how and what tools can bypass FRP for this phone now model is SM-G935A? thanks in advance!
