"D802 32gb shows only 16gb" issue

First: I already searched the forum, flashed kdz, flashed tot, downgraded from 4.4.2 to 4.2.2, installed ADB, rooted, moved files to /system/bin, chmodded, etc. Still the issue.
So, that's the problem:
- I was on 4.4.2 stock rooted rom and I flashed MIUI 4.7.4 (first official release for LG G2). It has not booted, so I needed to flash back a stock rom. And there's the problem. Strange to think, but maybe I flashed a 16gb rom on my 32gb G2. And there's my ex 32Gb showing only 16gb (10.62 available).
What I tried?
- flash official stock rom via Lg Flash Tool 1.8 modded
- flash official stock TOT file
- Upgraded and Downgraded (from/to 4.4.2 / 4.2.2
- searched for solutions and found the one that involves "rooting, usb debug, move sdparted files into system/bin, chmod them, use adb shell"
This last chance, is the one supposed to work, so, actually I'm stuck in the middle:
- stock rom 4.2.2 flashed and working
- developer options activated and usb debug activated
- rooted with ioroot
- installed ES File Manager (since Total Commander is not able to move files into system/bin even if rooted)
- moved files, chmodded them to 0755
- installed drivers / minimal adb
- launched adb, checked version (adb version, correctly shown), checked devices (correctly shows a multi numeric code)
- adb shell does not work. it does not show anything and remain stuck until I disconnect my usb cable
- on different conditions (that I cannot explain, due to many retries), I don't know why, it logs into "parted", but once there no command is working. everything I'm going to write will show again the command list of parted;
- on different conditions again, adb stops working again saying "permission denied" at adb shell.
Last but not least, there a problem rebooting the phone once chmodded the move files: it becomes slow, laggy, almost stuck and unusable, and it need to be flashed again (Normal Flash on Lg Flash Tool) to get working again, but loosing the rooted status, and forcing me to start over.
Someone could please help me? I'm freaking out!
Thanks in advance.

Next time, try searching harder.

[Q] Claro 801/803 stock firmware flash question

I have a Claro D801/803 which has been through hell and back with a QHUSB 9008 error -> 9006 error (without the right IMG files) and now finally I have achieved download mode.
Now if any of you gents can tell me how to go from here to Cloudy or CM (as in - which files to use), it will be much appreciated. I'm really really scared of flashing the wrong thing again. The Claro phone is extremely fragile...
Also two worrisome questions :
1. will this phone be carrier locked the moment I flash the kdz ?
2. Is this - http://forum.xda-developers.com/showthread.php?t=2432476 - the way to flash. In which case, should I choose CDMA in the flash tool as well as "Korean" as language. The instructions on that page are not entirely clear.

For the benefit of those who may have the same question about the Claro 801/803, here are the steps to follow. First - save a nandroid backup and also backup your photos, music,etc. Also check if you are starting from Jellybean or Kitkat.
1. Install Towelroot and just click the button to root. Reboot (even though it says you dont need to)
2. Download TWRP 2.8 from here. Unzip the zip file to get an IMG file. Put this on your phone.
3. Install "Flashify" from play store. Click the button that says "Install Recovery", then select "From file" and point it to the IMG file you put on your phone in step 2.
4. Reboot.
5. Check if recovery is working - the way to do it is simple. Power off your phone -> press "Vol-Down + Power button" until it shows a screen saying "Press power button for factory reset". At this point press power button THREE times. If you have the recovery installed, it will boot to TWRP recovery... otherwise your phone will factory reset and you will lose your pictures (so make sure your phone is backed up).
At this point you are ready to install ROMS !!
There are two main ROMs for the LG G2 right now - the Cyanogenmod 12 Lollipop and the Cloudy G3. The CM12 ROM can work on Jellybean baseband/radio while the Cloud ROMs need Kitkat Basebands/Radio. Now, at this point I decided to not flash Kitkat based basebands because ... well, I might as well wait for Lollipop to flash the updated baseband.
so I decided to go with CM12 - and flashed the CM12 ROM and gapps.

finally custom rom for lg g3 d858hk

hey guys i found custom ROM for d858hk version which is here
http://bbs.gfan.com/android-7892224-1-1.html
can be translated through Google but we need someone to explain to us in details.

I might able to help, I can read Chinese
let me know if you want any explanations.
it's based on lollipop 20d
- v1.0 LED not working, and this v2.0 fixed the problem
- rooted, superSU v2.46
- once you flashed the ROM, no need to flash the ROOT again
- busybox is in the system and no app not there
- works on D857 858 and 858HK
- it's a LIGHT version, there are functions that are deleted, like weather widget for example
- including deleted app inside the ROM, and could recover yourself
- app can write data to external SD card
- split view works for 3rd party app
- smart cover function removed, user can download the "deleted app" and put back into the system to get it working

Thanks alot i think this will help ...will try it now

but can we install twrp when in lollipop as i am now on lollipop
any ideas?

maybe these
http://bbs.gfan.com/android-7677473-1-1.html
one click Recovery installation
need to be rooted
1. extract files to computer
2 connect phone
3 turn on usb debugging
4. run Recovery.bat
---------------------------------------
old temp way, didn't say if it works on L or only KK
http://bbs.gfan.com/android-7727191-1-1.html

So...can any of you fluent Chinese speakers/readers help with the actual downloading of the ROM? It seems the rom is available at http://pan.baidu.com/s/1mg86X6o, but I get a little overloaded and can't figure out how to download from there. It seems to want me to log in, but I can't figure out if there's a non-login download ability lurking somewhere?

Do you have some screenshoots ?

Two things. First, I had the wrong link before. Correct one is: http://pan.baidu.com/s/1sjoKe4l. Second, I realized the reason is that the zip file is over 1GB and they force you to a "download butler". So the login thing is related to copying that file into your (QQ, for example) account and then you could download the file from there.

If anyone with a D858HK is interested, I was able to install this custom rom on my phone without any problems. I followed steps elsewhere to root (the one click version) and install TWRP. The rom is basically a slim version of the standard lollipop rom. If you end up deciding to install this, be aware that the Google Contact Sync app is not included within the rom and you'll need to also download the "deleted apps" zip file mentioned in the same post (link in OP). In the "deleted apps" zip, you'll want to grab the Gooogle Contact Sync apk and install that ... otherwise you can't get your contacts copied to the new rom. There were a bunch of other apks, but this one the only one so far that seemed like it shouldn't have been removed from the rom.
FYI, here are the version details of the rom:
Android version: 5.0.1
Baseband version: MPSS.DI.3.0.c6.2-00011-M8974AAAAANAZM-1
Kernel version: 3.4.0
Build number: (some chinese)1121561(more chinese)
Software version: D858HK20d-HKG-XX

So in total its not worth installing it? But anyway, thanks for your report!

I guess that depends on how easy it is to remove LG's bloatware and whether or not you need all/any of it. I personally didn't care for it anyway. But yeah, other than that, nothing special about the rom.

There were a bunch of other apks, but this one the only one so far that seemed like it shouldn't have been removed from the rom.

i believe there's a thread somewhere in this forum (http://bbs.gfan.com/forum-1508-type-10913.html) regarding d858 MIUI, could someone confirm? Thanks

My LG-D858HK phone hard bricked:
What happened/how I hard bricked the phone. I'd already rooted the phone with Marshmallow and then tried to flash phone TWRP by (mistakenly) using https://play.google.com/store/apps/details?id=b007.autorecd858hk when it hard bricked the phone. Now, the phone screen is black/blank and blue/red LED light flashing.
In addition, my PC doesn't recognise phone when plugged into USB port/s. Pop-up on PC screen says; “The last USB device you connected to this computer malfunctioned and windows do not recognize it.” And in Device Manager, I see a ‘yellow triangle’ next to LGE Platform Android Composite USB Device Driver.
I tried different methods to go into download mode and I’m not sure if any worked. Because, obviously, I can’t see anything on the phone screen to carry out procedures to fix phone in download mode. Moreover, I’m not even sure if the phone goes into download mode apart from a sound made from PC and the pop-up straight after.
PC always recognised phone when plugged into USB port/s before it was hard bricked.

You'd think with all the other posts about problems there'd be something here by now.
Always thank those who are helpful...and just ignore those who aren't.

Mine happened when I wiped Internal storage from twrp. This caused the phone to only see 4gb of internal storage. Came to xda and it was suggested to flash back original boot.img. once that was done 4gb issue was fixed and the radio was gone.
I did indeed try every solution offered (thanks again for all the effort, DrakenFX and others). But, I've come to the conclusion that this is not going to get fixed until XTE releases US images. For other people's sake I hope I am wrong, but I myself decided to proceed with the exchange where I bought it, as I was right at the end of my 14 days (newegg doesn't seem to give the 30 days that xte does). I may be out of an Axon 7 for a while, so for now I am on my amazon ads, Blu R1 HD (with ads defeated

Is there a guide to go back to stock for the A2017G?
i'm on B02 with root and the bootloader still locked.
Like to go back to stock now that ZTE is working on an update to give the A2017G an unlocked bootloader.

Hi all,
I am currently experiencing a bootloop on my Chinese Axon 7. Some of you regulars may have seen me asking in other threads because I've tried to fix it myself, but I've kind of run out of options. Sincerely hoping one of you can help me out!!! I'll buy the winner a beer or 2, haha!
Back story:
Was on B07 with root (tenfar's tool) with locked bootloader and had some issues with the ROM. Like vibrating when I opened the camera and battery drops. So I decided to upgrade to B09. Placed the OTA on SD card and went to: Settings -> update. Worked fine. So I connected it to my PC and made a dump (tenfar's dump tool) of my recovery and boot and stored them. Then I ran the Tenfar's tool, the B09 version and it went like the last one. But when I booted I didn't have wifi, and other issues came up. So I thought: did I make a mistake? So I read it again, checked the COM port again... all checked out. And used Tenfar's tool again. After that it didn't even boot anymore! It plays the nice boot animation and then gets stuck on the end screen with all the pictures.
So after that I restored my dumped recovery.img and boot.img. This is when I knew something was wrong: it still didn't boot! I reset data/cache in the stock recovery: no boot. Still stuck at the end of the boot animation.
What I've tried:
- Flashing the stock B09 update.zip with TWRP.
- Flashing the stock B09 update.zip without updater-script 'assert' and 'get-prop' line. TWRP says 'update.zip is corrupt'. Doesn't install.
- The I put it on SD card and internal memory and tried updating it with stock recovery: 'sorry you cant sdcard upgrade'. That's all it says.
- ADB sideload stock recovery: 'cannot load update.zip'.
I tried different ADB versions, Windows and Mac, different drivers... I tried formatting SD card as FAT32.. Tried different SD card.. Doesn't make a difference.
TWRP log says it can't pass the Zip verification when I try that. If I turn that off it says re.product.name is wrong. But I checked build.prop and updater-script. It's the same! But somehow TWRP comes up with a different one. Also tried removing getprop and assert lines from updater-script. But then it says: ZIP file is corrupt.
TWRP log after trying original, stock B09 flash:
http://pastebin.com/cJivE2TK
Build.prop: moved from /system with TWRP:
http://pastebin.com/b6rryc2n
Build.prop: ro.product.name=P996A03
Updater-script:
Code:
getprop("ro.product.device") == "ailsa_ii" || abort("This package is for \"ailsa_ii\" devices; this is a \"" + getprop("ro.product.device") + "\".");
assert(getprop("ro.product.name") == "P996A03");
But TWRP log: ro.product.name=cm_ailsa_ii
So, yeah, I've been trying on and off for the past couple of days in between work and travelling. Got a back-up phone so it's not that bad. But I really like this phone! It's just been such a pain in the ass the past few days...
I tried researching online and reading all the XDA posts. It is my fault this has happened and feel such a newb for not being able to fix it myself
Many thanks in advance!

Dear All,
ZTE Axon 7 A2017 (Chinese version) Stuck on Bootloader mode.
Device after power on will Stuck on ZTE logo even power button press longer also will Off and came back to square one and the only way to power off is via selection on bootloader page via volume button which consists of Recovery mode, Power Off, Bootloader and some other mode which I can't recall.
History of this issue. Please bear with long story.
Manage to install MM ROM with B13 via sd card installation via update software in phone setting. follow by Unlocked bootloader and Install TWRP 3.1.1.0 then try few different ROM until one day when I use Xiaomi flashtool my PC crash half way through during flashing resulting in device with Pure Chinese ROM and TWRP also got corrupted, when I said corrupted because I install TWRP 3.1.1.0 but when I go to Recovery mode it shows TWRP 3.0 something. with this corrupted TWRP when I try to install ROM it will show loading but end result is NIL meaning same ROM nothing change.
Until this stage I never did a TWRP backup because all this while the ROM is Not my type of ROM from this junction when I boot back to TWRP and I did Advance Wipe most of it except external sd card thinking that I may be able to install fresh TWRP but my Recovery TWRP is residing in phone storage resulting in No more TWRP recovery software. next thing I did was I connect phone to PC and ran adb fastboot tool to detect device and managed to detect device in recovery mode and I make decision to Locked back the bootloader and did just that and Locked bootloader is Succes and it also Erased everything during the process.
To cut short the story after Locked back bootloader only Bootloader mode is accessible and when I connect to PC and enable Recovery mode (Black screen) and EDL mode (Black screen) from Windows PC Device Manager COM port able to see Qualcomm 9008 for this 2 mode.
I must admit after few days of trying to resolve this Stuck Bootloader issue I almost give up.
Then I remember this Woodo magic by jcadduno which recommends XM flashtool version 2016.08.30.0 but unable to flash after trying few version Xiaomi flashtool and the very latest and I mean from Xiaomi Flashtool webpage http://xiaomiflashtool.com/
version 20170425 that break the ice and finally able to load A2017U ROM because this US ROM my phone No Network detected.
From here onwards I unlocked bootloader and install back TWRP (Installation of TWRP via Axon7toolkit) because of Network issue since I got TWRP I install back A2017 ROM but still Not satisfied because Chinese ROM certain Apps having issue because of Google services and I chance upon this Conversion A2017 to A2017U ROM (Hybrid ROM caused ROM is US and Modem from Chinese Modem)
that I'm stay put right now and my phone now is A2017U model.
I hope this experience can help others with similar Stuck bootloader and those who wish to convert A2017 to A2017U ROM.
below is the link that I described Woodo magic.

I am stuck in a position where I can restore my nandroid backups but get Error 7
when trying to reinstall any Rom on a2017u I was able to fix the unlocked bootloop
by the EDL method. The Rom's are the same as the backups. I think I tried to role back to B29 Causing the bootloop) and have had problems ever since.
Should I try flashing A2017Uv1.1.0B32_Bootstack_by_DrakenFX since the Rooms are all B32?
The B15 and B19 Nandroid's still Restore fine.

Hello all,
i don't get onto forums very often but i thought this was a nice one to add to. i've rooted a few motorolas, a few ztes, a cat; i've also bricked those ztes, cat & a few samsungs. i'm dealing with two Axon7U's; one is factory MM-b29, the other is N-b35.
while screwing around with TWRP, i bricked the b35 (the b29 has been bricked for a month at this time) after i had it almost perfected. by perfected i mean a custom recovery & root user access fully acquired. with DrakenFX's {YOURS; thanks so much. i'm learning to get along with linux} extensive files created to save people from themselves i was able to unbrick the b35. albeit its CELLULAR DATA became unhinged; that's something i could've lived with except it was a loaner and had NO CAMERA! it's camera (along with the ability to push both volume buttons at once for say EDL mode...) was damaged having been beaten across a steering wheel several times. so with my newfound unbricking superpowers i decided to take another crack at the b29. managed to get it unbricked but couldn't get it setup with both TWRP & SuperSU without losing one, the other or, both. at times it didn't even boot up. i was doing pretty much everything cited above for reasons 'why'. best way to learn is by trial & error (if one can afford it).
the b29 is rooted right at this moment; i'm working on it as soon as i leave this posting. i used Axon7_EDL_Tool. i used Axon7root. i used MiFlash. i used Fastboot. I used ADB App Controller software too. back & forth i fought for three days mostly due to downloading glitches and i prevailed. i manipulated a stock OTA full system update.zip by happenstance and it Auto_Updated over itself. in other words it already had the same ROM installed. i don't know what it tested to realize it needed to update to what it already had. it didn't have CELLULAR DATA either. just like the b35, it broke somehow while flashing TWRP or SuperSU. funny thing is it still wanted to update that same ROM after it did. while perusing the system update setting(s) i noticed it had downloaded N-b15 and it wanted to update b29 AGAIN! i opted for the Nougat update. it did alright and appears to have fixed it's CELLULAR DATA too. i haven't looked at it since but i'm confident i can gain root user access with a minimal amount of effort.
The main problem i've had with dealing with bricked devices is the age of the file downloads. most of them are simply GONE!, expired links and whatnot. if i'd had a clear path say from a custom recovery and rooted boot image of my factory version or the path that leads to it, i'd have been fixed up long ago. i've found partial 'paths' if you will that almost get me there but no quite all the way. flashing images & zips through fastboot are different from their counterparts entered through TWRP or Emergency Download Mode which of course are both different too. three different ways to get into one's phone makes it almost impossible to keep them perfected.
i'm not sure i did what i'm supposed to regarding this thread. Thank you DrakenFX for your time & knowledge; you've saved my old Axon7!

Hello all update;
b35 Nougat phone is retired. b29 managed to update itself to b35 7.1.1. however, its CELLULAR DATA is still broken. i haven't managed to figure out how or where it's broken so i cannot fix it.
what i'm trying to do now is flash Magisk instead of SuperSU and using a TWRP version 3.0.3-1. heck i've used all of TWRP's versions in my efforts to reacquire CELLULAR DATA.
crazy part is the phone knows its CELLULAR DATA carrier and freely displays all of its hookup info. this is very frustrating.

lineage 17 on samsung galaxy a20e

there are some instructions how to install twrp or lineage on nnthe samsung galaxy a20e. it took me a while to manage it, for one part because it seems sometime i did not do everything exactly like it was described (old fault of mine...) sometimes i found some explication in another instruction.
this is why i post my experiences, to encourage those who also struggle with problems, don't hesitate, sometimes it only takes a bit longer, but also because some things i still don't understand, maybe somebody can explain me what happened..
naturally, firsty of all i first had to install twrp. so i searched for instructions and found some, including liks to download the twrp.tar for my model. some of them i was able to flash by odin, but when i then restarted the phone it only showed a black screen with some pink in the middle, with some fantasy i could read a slight samsung or samsung a20 in it. this happened when i tried to restart in recovery to flas disable-dm-verity, also when i tried to restart direct to system. with all the attempts i got very experienced in flashin back stock rom...
then i found a working recover after restart to recovery i got my twrp screen and was able to flash the no-dm-verity or magisk.
so next i tried to flash the lineage (unofficial lineage 17.zip) but always got the message invalid zip format. tried to unzip and zip again but no way. so i thought i might get lucky with adb sideload, entered the twrp advanced and clicked adb sideload, the screen told me starting adb sideload but the phone could not be detected by the computer. the computer detected it when switched on or in fastboot, so it seems the sideload did not really start.
so i searched the interenet for roms because i really wanted to get rid of google and a million of apps in the stock that i don't need. i found the links to andyyans gsi and several other zips.
as i was not used to the gsi installation i thought i better stick on what i know and tried to install another zip. but most of the time i got the invalid zip message or the zip is for another phone although i downloaded it for the a20e. but then twrp accepted the crdroid.zip (eureka) i downloaded, i was very happy, after the instalation was finished i restarted the phone and the screen went black, turned off and it seemed not pressing to download, to recovery or to start changed anything. i also tried with pressing vol up, vol down and conecting with computer but also no downloadmode started. so i pressed very long always several buttons and after a while the phone vibrated by pressing long vol down and power, but no screen. after it vibrated sometimes like this i turned to vol up and power, it vibrated again and finally twrp started. although the phopne was fully charged when i started the process, it now had only 8% battery.
so i charged the phone again, flashed the stock rom and twrp to try again to find a solution. at this time i also found an instruction that explained why after flashing twrp the system can't recognize the folders (downloads, music... ) and only gives them combinations of letters and ciffers, i have to decrypt it in twrp, wipe, format data, yes and this problem is solved. i don't know it happens always and who made the instructions to flash twrp thought this is common knowledge but in the first innstructions i read it was not mentioned.
i tried again to flash zips and now got a funny eroor message from twrp, unable to zip, this zip is for a20 but this phone is a a10. i tried another zip, the installation started and in the text i could see that it was for a10... so somehow twrp was sure to live on na a10, how could this be??? i thought maybe the twrp was for the a10 (it was a 3.4.x), so i again downloaded a tar directly from the page of twrp for the a20. but when flashed this twrp (3.5.x) and tried to restart to recovery (or to system) the phone was still in downloadmode and refused the custom rom. i had to flash back to stock, then flash again the twrp3.4 that thought my device is a a10, then i could flash the new twrp3.5 i was sure it was from the original site and for my device. i don't know the 3.4 was patched, i got the downloadlink from one how-to-site, but i did not read anything that it was patched...
but after testing all the zips that did not work, and also with the new twrp i was not able to sideload i decided it is time to learn how to handle the xz. so i extracted first the lineage 18, installed it by clicking install image (after wiping) but again the phone turned black and i had to press a while to get twrp restarted and the battery again was nearly down.
the same process worked with the lineage 17, so this is what is now innstalled. both where the correct ab versions, i checked before with treble info what version i need.
so, can anybody explain me
-what happened with my battery when the phone turned to apparently death?
-why could twrp think my phone is a a10, would a twrp for a10 work on my phone?
-is it possible that the sideload feature does not work on this phone?
¡¡¡and many thanks to all those who upload roms and instructions so people like me can make their phones a bit more like they want them!!!

The first time I flashed my A20e (SM-A202F) had the same problems with finding the right TWRP. I cannot answer your questions, but I can tell you what I do.
Beforhand: unloock the bootloader. Upgrade to the latest Samsung firmware. Download AndyYan's 18.1 LineageOS GSI arm64_bvS. Thought arm64_bvS-vndklite can work as well, I found that bvS has less bugs.
After installing the Samsung drivers and the adb stuff on a PC with Windows, I install Odin and flash with Odin the attached TWRP (AP), while phone is in Download mode.
I then go to recovery (TWRP) and if the folders and files are encrypted, I format, then yes. I wipe 4 things: dalvik, catche, system and data.
I then move the GSI image file inside the zip (not the zip) by drag and drop on my PC. Then in TWRP I click install, select image, not zip, select system and flash. Then I reboot to system.
I never had any problems with this installation process. The bvS has a bug with the Lineage music app, but simply install a local music app, such as Musicolet or AIMP from the Aurora Store (from F-droid).
On the camera side I haven't seen any app that significantly improves photo quality. My recommendation would be FreeDcam from F-droid. Use it on special occasions, as it tends to heat the phone.
