[G2 General] Art Vanderlay:
It's very simple. If you look in directory

Dev/block/platform/msm_sdcc.1/by-name you'll see all the partitions there. Boot, aboot, laf and everything else.

Just run the same command but change the partition name to another one.

Eg. dd if=/dev/block/platform/msm_sdcc.1/by-name/system of=/sdcard/system.img

dd if=/dev/block/platform/msm_sdcc.1/by-name/tz of=/sdcard/tz.img

And so on. It's critical that your spelling is correct so check it against the OP.
[G2 General] igos2:
Thx, also found an app in play store that to it automaticaly, partition backup & restaure

I need your help, i m still a beginner with flash, root and all these stuffs.

lg g2 touch misbehave after update

bro just contact me i will solve ur issue.
[G2 General] Art Vanderlay:
If the flashtool is seeing the wrong model number you need to hex edit your kdz file before you flash it.

See this thread http://xdaforums.com/lg-g2/help/solution-lg-g2-variants-lg-flashtool-t3109637
[G2 General] ultimat971:

[G2 General] Sunandroid:

[G2 General] Art Vanderlay:
Yeah the ls980 has both.

help to reinstall recovery

Hello everyone!:) I've been reading the whole thread about the problems of smartphones refurbished.

recently bought a LG G2 ebay at a cheap price the seller made it clear that the equipment is refurbished but did not pay attention to this detail because I never thought that these phones would have such serious problems when wanting to update or install a custom recovery.

my LG G2 is apparently the D800 model at & t the phone came with android 5.0.2 lollipop, now a few days ago try to install a custom recovery with the app AutoRec but did not work when pressing the flash button nothing happened I thought it was the version then install another version of AutoRec and nothing happened then I found in the playstore an application that automatically installed the TWRP recovery then i try with this app but apparently not install the recovery on the other hand I destroy the stock recovery.

:confused:I wonder if there is some method can i use to retrieve the recovery stock or install a custom recovery as I can not do a factory reset, when I try to enter the recovery throws me a series of messages and deduced that because the recovery not found

I would greatly appreciate if I can help me:fingers-crossed:
[G2 General] raptorddd:
Then you didnt read well enough, if refurbished you need to open phone, and find out what variant you have... if its says d800 but if you open phone and check MOTHERBOARD ONLY then what ever the motherboard says in there thats your variant... go with what its on the motherboard. then flash stock rom for that to recover stock, then you can proceed to use root and other roms always using what the motherborads says...
[G2 General] Art Vanderlay:
Don't just flash anything in sight. If you got a d800 on lollipop then only flash the d800 LP autorec. No other various apps you might find on the playstore. That's a disaster waiting to happen.
[G2 General] Mtr.Edd:
then tells me that the only way to reinstall the recovery is flashing the phone with a stock rom depending on my the model have on my motherboard? It is all I need to do?

I read in a post in this forum something about making a backup of the EFS partition because there some phone information is saved there as the IMEI

then someone can tell me how to backup EFS first with adb

---------- Post added at 06:14 PM ---------- Previous post was at 05:47 PM ----------

I've been looking AutoRec LP in play store and I found the description how to solve the problem about the flash

now what happens if I use AutoRec on refurbished phone? taking into account that the app was scheduled for phone oem

someone already used in a refurbished phone?it works?

I appreciate your answers.
[G2 General] Art Vanderlay:
Does your phone still boot up normally?

If it does then you can backup the efs by starting an adb shell and running these 2 commands:

dd if=/dev/block/platform/msm_sdcc.1/by-name/modemst1 of=/sdcard/EFS_Backup/efs1.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/modemst2 of=/sdcard/EFS_Backup/efs2.img

(and obviously put these 2 files in a safe place)

Autorec flashes recovery, bootloader and laf image. That's why it's so important to flash the right one.

Some refurbished phones, not all are put together with different parts and packaged as a different variant. So if you have one of these frankensteins then you should be getting a secure boot error or security error after using autorec.

If your phone boots up normally and you still have download mode then that's a good sign.
[G2 General] Mtr.Edd:
yeah my phone works normally just the recovery not work that's why i try reinstall the recovery stock or custom.

I have done the backup of the EFS folder only had to change the target directories because my phone does not have the sdcard directory the changes were as follows:

dd if=/dev/block/platform/msm_sdcc.1/by-name/modemst1 of=/storage/emulated/0/EFS_Backup/efs1.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/modemst2 of=/storage/emulated/0/EFS_Backup/efs2.img

in the by-name folder on my phone there are several files:

aboot
blus
boot
cache
carrier
dbi
dbibak
DDR
drm
encrypt
eri
fota
fsc
fsg
grow
laf
misc
modem
modemst1
modemst2
mpt
pad
pad1
pad2
persist
rct
recovery
rpm
rpmbak
sbl1
sns
spare
ssd
system
tombstones
tz
tzbak
userdata
ve

anyone knows for they are and if they are important to make a backup?

I also found in my phone storage 3 .img files with the following names aboot, boot, recovery laf and apparently these files are a backup that made the app AutoRec because before using AutoRec were not there

question can use these files to try to recover the stock recovery?:confused:
[G2 General] Art Vanderlay:
That's perfectly fine. The only thing that matters is that you keep them in a safe place.

Absolutely :good: Those 4 partitions are the most important ones you need. Aboot is

your bootloader and laf is your download mode. The other ones in by-name aren't really worth

backing up, but it wouldn't hurt if you did.

Flashing those files should bring your recovery back. Make sure you flash all of them if you do.

I have bricked my refurbished LS980(on the motherboard) a billion times. Everything is on the xda, it is actually so easy to revive it. LG G2 ain't die!!!

I am using any kind of kernel or roms with no problems, so from my point it is safe to get one of these and tamper with it.

Brands locking lte bands on smartphones to force people buy more devices. my only problem is with LTE, since my country uses the bands 3,7 and 20, LTE is not working, I found some guides on XDA about unlocking bands in qualcomm devices but could not figured it out with limited knowledge(for the first time). I assume it is possible and not so different than changing IMEI.

Here is one of the guides : http://xdaforums.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059

I am asking for help to put my g2 to diag mode and make it recognized in qpst...thanks
[G2 General] Sunandroid:
I can't do more than that:
[G2 General] zhjackss:
Same here tried STOCK, CM/AOSP and CUSTOM roms...

The seller whom i bought my LS980, was using some kind of IMEI changing program (probably QPST's RV manager), i mean he was able to read the phone and assign IMEIs. Maybe he was using a Box i dont know. Anyways, im sure its pretty possible to unlock the bands and deal with this stupid restrictions of brands. Also, i read on xda that a man claims that he unlocked the bands of his isai l22 G2 (japanese one)

Thanks for your interest

[MENTION=5744495]Sunandroid[/MENTION]

I've managed to connect my ls980 in diag mode and successfuly added all of the GSM/WCDMA bands and the LTE bands in the guidance of a tutorial for OnePlus One. I am testing it.

for GSM/WCDMA bands i followed this guide: http://xdaforums.com/oneplus-one/general/guide-unlock-aditional-bands-qualcomm-t2877031

for LTE bands i followed this: http://xdaforums.com/showpost.php?p=56577252&postcount=455

without problems i followed and finished the steps. basically i should be able to use the bands below:

GSM: DCS-1800/P-GSM/E-GSM/GSM-850/Railways-900/PCS-1900

WCDMA: Band I to XI

LTE: Band 1, 3, 4, 7, 8, 12, 13, 17, 19, 21

If LTE works i will do a guide.

UPDATE EDIT

Using stock based rom and custom kernel, going into DIAG mode is possible and changes stacks (you should disable USB debugging and plug device in only charge mode so that qpst and qxdm works)

I've tested it for a day all the bands GSM,WCDMA and LTE

I could change GSM and WCDMA bands successfuly I've tried many variations on LTE nv values, I am pretty sure it stacked and unlocked some of the bands but could not get it worked.

But I assume problem is below, this is why i cant get LTE work, I entered a value that only the bands 3,7,20 supposed to work but ##DATA# > LTE settings shows me this:

Any of you guys are experiencing a massive battery drain problem on your LG G2 phone? I bought a LG G2 D801 off eBay. The seller is "cell-world2016"
[G2 General] zhjackss:
Post your battery stats. But i dont think its a massive drain, its just your battery is old. When you buy a refurbished or used mobile you must also buy a new battery. I suggest you to buy this extended german battery called powercell akku on ebay which is 3200mah.
[G2 General] SaintClive:
I bought the original battery from amazon for like $10. Thanks for the help!
[G2 General] Fendeur:
I just ordered an lg g2 800 from the same seller as you, could you tell me how is the phone, is it really ''new'' as it says in the condition of the phone? How bad is the battery? Does it have bad imei? any scratches on it? :confused:
[G2 General] SaintClive:
I am the same guy from reddit :P (salmonb0y)

These are the things I noticed:

1) Massive battery life drain

2) The phone is 24GB not 32GB

3) The IMEI code is invalid and not unique

The condition of the exterior looks new, no scratches whatsoever.

Sent you the conversation between me and the seller via Reddit PM, as I am not allowed to post links here.
[G2 General] raptorddd:
2) no phone ever shows 32 GB mine shows same.. some memory its reserve to system ect. then you get 24gb of sd card . data.

you guys have to make sure you are really getting a d800. some phones are refurbished and most d800 that when flash rom it has ghost touch and some other things . means that it isnt a d800 some are ls980... even they show imei as d800, imei can be edited.. just in case you guys did buy refurbished, and to find out what variant you really have .. is to open phone and check motherboard then what ever the motherboard says thats what youll have and be flashing...
[G2 General] Art Vanderlay:
Hey guys. There are 2 videos that I have linked in the OP, one that shows how to open the rear cover and one that shows how to access the motherboard. Unfortunately the latter one has been made private by the owner. :(

I'll try to replace it with another one if one exists otherwise I'll have to make my own video. I'll post again when I have something.
[G2 General] Aqib Ayub:
Hey. I just bricked mine too but its working fine but I cant get into the recovery after flash twrp from official app & it shows ''error boot certif.......'' .I had same problem mine is not d802 ,it was d803 but I didnt know which one (Rogers , bell etc) thatsway it showing error .

Please help me I tired autorec but didnt worked.. :(
[G2 General] raptorddd:
the best way to go i think its to go back to stock firmware and start from scratch. i dont know that variant but heres the link to go back to stock..

I removed my back case and There was written LS980 everywhere but when I flashed "LS980ZVE_03.51102.tot" it gave error that device model in different.

What should I do?
[G2 General] raptorddd:
the only way for sure to know is to look at motherboard under it it says what model/variant you have. some have 2 different variantst stickers when you open the back.. first thing is see what the motherboard says... then proceed to flash that firmaware
