hi,
this is a guide for real helpless people, that got a V20 H918 T-Mobile out of the box and have no idea
what to do, to get TWRP and root. and since on this phone its a REAL hard odyssee if youre not a pro,
and you dont want to spend days and weeks to pick up countless small puzzlepieces to finally get all together up and running, i decided to write this guide. im no pro myself, but with countless hours of reading and try and error, misery, headaches and brainpain, i managed to get this thing running all right with working downloadmode,
newest TWRP-version and 20H oreo 8.0
so far, everything seems working good. ill play around with this version and if i encounter some crap, i will edit this guide later. sadly most "newbie-guides" here, are from pros for advanced users with decent knowledge. so when u start from zero, you dont understand half of what is written. thats why i will keep this guide as simple as possible, with some side explanations. its a lot to read and a lot to do, but this way works!
what we have before starting:
a V20 H918 t-mobile 20H oreo 8.0 with bootloader locked. simply a crippled standard phone.
what we will have after this guide:
a V20 H918 t-mobile 20H oreo 8.0 rooted, with unlocked bootloader, working downloadmode,
and newest TWRP-version.
with twrp u can backup your whole system "as it is", means u fukk up your phone, simply go to twrp-recovery, restore your backup and you have your phone up and running 100% as before all went down the drain. simply and easy. just like a new installation of win10, but in 5 minutes. u can flash custom roms, kernels etc., install all kind of stuff, no need to pay for apps anymore, get rid of obnoxious bloatware, just 100% freedom and the full potential with the V20 (which is the last phone of its kind with exchangable battery, which is why i got myself 3pcs of it )
sidenote: get yourself some extra protection foils so u can change from time to time.
also get yourself 1 or 2 10000mah powerbatterys from aliexpress (perfine) with protective rubbercase, of course, they dont have the printed-on mah, but at least a considerable amount, so that your phone will last at least 3-6 days. my V10 lastet 11 days normal usage with zerolemon powerbattery. unfortunately, these retards refuse to send to europe, and as far as i know, theyre not producing for LG phones anymore, so aliexpress/perfine is whats left.
the rubbercase gives the phone a superior protection, adds a serious amount of weight and will stick in your hand like glue. it is by far less likely to drop out of your hand like these glass-phones for imbeciles. and if it drops, the rubbercase grants excellent protection. my V10 dropped countless times, still working perfect.
but lets get to the guide now.
at first, we will unlock the bootloader. without it, you wont be able to do anything.
unfortunately, LG produces great phones (with great audio!) but terrorizes the users with their strict anti-root attitude. it seems it gets harder everytime to root and unlock the bootloader. i remember back in the days old samsung devices, had been rooted in no time. this one here cost me about 2 weeks.
on this phone, u simply cant hook it up to the pc, and unlock the bootloader with adb. it will be recognized by the pc, but as soon as u enter fastboot, nothing will happen, no command works.
the solution is a FWUL (forget windows use linux) usb-bootstick, with that u boot your
pc into a custom linux (i think) only here u have full access to your phone via fastboot and can unlock the bootloader in no time. it will not work on win10 !
- first, get rufus, a win10 tool, with that u can create boot-usb-sticks.
https://rufus.akeo.ie/
- then get the linux FWUL image (only 15GB version is still up)
https://androidfilehost.com/?w=files&flid=214529
- unzip the linux image to your c drive or your desktop.
- start rufus and select your usb-stick (it should be 30gb+ in size)
be carefull not to chose any other drive or stick (it will get erased completely), better double check.
- select the image you just unziped. (i use 7zip for unzipping)
- leave all other options as they are, press start. when dialog-box pops up, chose DD-mode !
- now waste some time, as it takes a long time to create the bootstick (in my case about 30min)
- when the stick is ready, in my case it couldnt be recognized anymore in win10, its just a raw-drive, that cant be
opened. thats allright. dont worry
- now close down all applications running and insert the created bootstick. (at this time u might consider using a
separate laptop, so you can follow this guide here at pc and use the laptop with linux running, thats what i did)
restart your pc, hit F2 or F8 oder DEL or whatever to enter bios.
select the created stick as bootpriority nr1. so that the system will use this stick as
the first bootmedium to boot from.
- u get to a screen with 9 bootoptions to chose from. chose the first one. it should now boot into linux.
when password request pops up, enter: linux
- u reach the "desktop"
connect your LG V20 H918 20H via usb-c to the pc, which has linux running, make sure that
developer options are unlocked, OEM-unlock and USB-debugging is enabled and u chose picture transfer protocol
(PTP) as transfer-protocol (also in developer options). if PTP doesnt work, try media transfer protocol.
watch your V20, at some point it will ask for confirmation of connection , click OK.
in linux, click on the up-arrow in the most downleft corner and chose "terminal emulator", which is
a pendant to windows shell/command-line.
- here you can execute the adb commands.
first, check if your V20 has been recognized by your pc with linux running.
type: adb devices
it should appear a message like:
* daemon started successfully *
LGH9182bfblablabla device
that means, that your V20 has been recognized correctly. now you can reboot it in fastboot mode.
type: adb reboot bootloader
your V20 screen goes black and seconds after, it restarts in bootloader mode ready for unlocking.
you might get a red warning that your warranty is void if bootloader is unlocked. cool.
type: fastboot oem unlock
wait for response, your bootloader is now unlocked.
u can check by typing: fastboot getvar unlocked
it should say: yes.
the bootloader is now unlocked.
now we will replace the standard recovery with twrp on the phone.
this step will be a little confusing and complicate, just follow the steps, and it will work.
since we cant flash twrp with adb, we have to use the linux bootstick again.
but before, we have to downgrade the 20H version to 10P, bcuz the next stepp will not work with 20H !
so you get the following:
DOWNLOAD H91810P KDZ FILE
https://androidfilehost.com/?w=files&flid=282709
after that, download LGUP (the LG tool for downgrading from 20H to 10P)
and uppercut (dont know what uppercut is for, i just used it instead of running LGUP directly and it worked. its supposed to recognize the phone/driver automatically)
http://downloads.codefi.re/autoprime...sh_Tools/LGUP/
and download the recent LG-usb drivers.
http://tool.cdn.gdms.lge.com/dn/down...=UW00120120425
install LGUP, uppercut and usb-drivers.
connect ur phone to pc in download mode.
turn of phone, press and hold vol.UP button and connect usb cable, small message appears, phone is now in download-mode and waiting.
now run uppercut and hope, that ur phone will be recognized. if not, think about, what kind of restrictions u did to ur system, like OnO-shutup or xpantispy (both great programs to keep win10 from calling home to scum gates) or whatever. in my case, it ONLY worked, after i reset the OnOshutup settings to recommended. so the phone get recognized correctly in LGUP (if not, try laptop or different pc), select upgrade and select the downloaded 10p KDZ file. press start or go, and wait until the procedure is finished.
now your phone is downgraded to 10p.
now we go back to linux, we connect the phone in downloadmode with the pc/laptop where linux is running,
(turn phone off, hold volUP, connect usb-c-cable with linux-pc/laptop, phone will start in download-mode.)
make sure, your laptop/pc has internetaccess.
on the linux-desktop, click on the LG folder, inside, click on LGLAF runningnaked.
a terminal-window opens.
type: git pull
type: git checkout h918-miscwrte
type: ./step1.sh
now we have flashed twrp onto downloadmode. why? i dont know, thats the way it worked for me.
we dont want twrp onto downloadmode, since twrp is a recovery. so the next step is, to flash the newest twrp version for H918 to recovery. at first, we will gather all neccessary downloads, after that, we will flash them one by one. that way, you dont have to get your micro-sd card out of your phone again and again. we put all together on the card, put the card in your phone and we are almost done. for now, have your micro-sdcard connected
with your pc and download the following:
twrp-3.4.0-1-h918.img
from
https://dl.twrp.me/h918/twrp-3.4.0-1-h918.img.html
and put this .img file on micro-sd card.
then download (and put on sd-card):
MAGISK ZIP DOWNLOAD (for root)
https://github.com/topjohnwu/Magisk/...gisk-v16.0.zip
then download original 20H firmware(and put on sd-card)
H918 20H
https://androidfilehost.com/?fid=11410963190603864639
you remember, we have now twrp on downloadmode
for restoring download-mode, download (keep on desktop or c):
H91820h_00_1115.kdz
https://lg-firmwares.com/downloads-file/17076/H91820h_00_1115
then download the firmware extractor:
https://forum.xda-developers.com/attachment.php?attachmentid=3975633&d=1482337024
ok, lets see what we have now:
we have the phone bootloader unlocked and twrp on downloadmode. we can access twrp when we start the phone in downloadmode (hold volUP, and connect usbcable, phone will start now in twrp.)
we dont want twrp on downloadmode, we want twrp as recovery. and we want to restore the original downloadmode. for that we do the following:
unfortunately, the neccessary file for flashing orignal downloadmode is not online anymore, so we have to extract it from the 20H firmware with the firmware extractor (thanks to logical gamer for his guide)
https://forum.xda-developers.com/v20/how-to/guide-h918-restore-laf-partition-t3804728
Extract WindowsLGFirmwareExtract vx.x.x.x. to your desktop, and open it up (preferably in it's own folder).
u might have to install framework 3.5 for it to run.
Select Open across from KDZ/TOT file, and browse to your KDZ (H91820h_00_1115.kdz)
you download previously and double click.
After it loads the kdz check H91820h00.dz, and click Extract KDZ.
Close and re open the program this time Click open across from DZ File in the folder where you placed WindowsLGFirmwareExtract you should see a file called H91820h00.dz Double click to open it.
Check laf_6.bin then click Extract DZ.
put this laf_6.bin on your micro-sdcard. thats your original downloadmode we will flash now.
ok, now we have our micro-sdcard with twrp, magisk, laf_6.bin and H91820h.zip.
put this mirco-sdcard in your phone. start the phone in downloadmode.
it will start in an older twrp-version. in twrp, go to install and select install img
select the twrp 3.4.0.1. img and on the following screen select "recovery"
swipe
this will flash the 3.4.0.1 version of twrp onto recovery.
then go to reboot into recovery. it will now boot into the newly flashed recovery.
then go to wipe, advanced, and select everything EXCEPT micro-sdcard!
this will totally wipe your phone (except twrp), so u can flash the 20H firmware onto a clean phone.
then, go to install, select H91820h.zip. this will flash your original oreo 8.0 firmware.
after that, go to reboot into recovery.
go to install, select magisk. install.
this will root your phone.
after that, reboot into recovery, go to install, select install img, select the laf_6.bin, and select "download"
now the original downloadmode has been restored.
now you can reboot into system, your phone will start as on day1, with new twrp on recovery and root.
i did a complete backup in twrp, so i can get back to a day0 clean install whenever needed. i will do a second backup with twrp with all the stuff installed and working ok and place this on my sd-card. so when things go bad, i always can go back to this state in no time.
congrats, your done. and me too . gonna get a cold one now.
hope this guide will help someone. in case, just drop a like/thanks/or just a short note.
its a long guide, and im no pro, if i made some mistake pls. tell here and i will correct.
thx to all the pro-guys for helping the helpless.
Hi
Im on v20 H918 firmware 10p with bootloader unlocked.
I tried with dirty cow but not works with lafsploit i have a Problem with rufus for create a bootable Linux.
Pendrive is 32 GB i followed your setting but my PC boot only in windows 7.
I succesfully unlocked a h990ds with dirty santa but for this model is not supported.
Can you help me
hi
i tried with dirtycow also, didnt work.
thats why i eventually came to the method i described.
teling by your short description, your next step would be to create a bootable linux-usb-stick, and to find a pc where it will boot correctly. the stick didnt boot on my main pc ( i dont know why, it just canceled with an error),
thats why i had to use the laptop where it worked.
Thanks for the guide man! Very funny and fun to read. I can't wait to turn mine into a 4-day brick like yours. #lastphonewithbatteryrevolution
Sadly I got the dreaded encrypted error at the end though when booting. Everything else worked fine.
After the encrypted error though I formatted and flashed LineageOS 17.1 and then magisk and still keep getting error 1. Even tried Lineage recovery and still same. I think maybe a problem with Magisk 16 itself.
Anyway it works fine just no root.
Edit: Had to flash Magisk 21 and it worked
Thanks for this tutorial. I was able to get my V20 rooted with minimal trouble. The only major trouble was finding a computer that will fully boot into Linux and the only minor issue was locating the UPPERCUT but I was able to find it. Link below.
It's probably worth mentioning that I had to rename laf_6.bin to laf_6.img in order to flash it in TWRP. Also, at the time of writing, the latest version of Magisk is 22.0 but I used Magisk v21.4 instead because it had a zip file (Magisk-v21.4.zip) available for download so that I can flash it via TWRP. Link below.

cool, glad this guide helped at least a little bit. my v20 still works great, no issues so far. as a side phone for unwanted persons, i still use my v10 with powerakku and rubbercase "brickstyle" every time i hold a regular phone from other people, it feels weird since these phones weigh like nothing, and i have to focus not to slip it out of my hand. i love my bricks
and by now, about 4 month later, reading this whole guide, to me its still strange and hard to follow. there is no way to get through this without reading everything possible about it and become familiar with all the technical terms.
I have a h918 with an unlocked bootloader and it's downgraded to 10p. The shell script fails everytime to a hash check. I've run it 4 separate times with the hashes being the same every time. So it looks like the file has been updated but the hash hasn't.
I'm coming late to the game and it seems most of the guides are out of date. I'd appreciate any help I can get.
Update: It works fine. This is by far the easiest guide to follow that I've found. Many thanks! I did have to follow xstahsie's tip.

I followed the guide after I rooted and installed Lineage OS 18.1. I had to remove LineageOS because it was bad with response, couldn't see hidden wifi, and just ran hot. So I followed your guide and I am in a logo bootloop and get the reminder to lock the bootloader everytime it starts. Any suggestions for getting past the bootloop?
I fixed problem by installing LAF you referenced and then LGUP to 10p kdz. However I noticed two things.
1) Whenever I boot up I have the nag message to my bootloader. Any way to address this?
2) If I try to follow steps above to install 20h, I get a decrypt message in TWRP after I flash 20h and before Magisk. Anyone see this? I didn't encrypt my storage before hand.

You're stuck with it, it's just the way it will be from now on.

I don't remember seeing that. I probably didn't care if it did show up since it was a new install from scratch anyway.
Does encrypting the phone work after following this guide?
hey there, cant help u with the encryption thing cuz thats far beyond my knowledge. some weeks ago my phone dropped, and a tiny crack on the edge appeared. what i didnt know was that this crack is the beginning of the end of the V20. heres the story short: small crack over time leads to a bigger crack, bigger crack multiplies and u have some more cracks covering the whole screen. also the screen can pop off and hanging loose a little. in my case 4-6 weeks and i have to get out phone 2/3 which i am setting up using this guide now. fortunately i left myself a huge pyle of information on how to do this when starting at 0. over time u forget EVERYTHING u have done, so having these infos is hammering.
lucky me did i save my internal memory of phone 1/3 bcuz 30min later the screen was totally fuqqed up, no access no chance of backupping internal memory.
so heres my recommendation:
DONT drop your phone. even in my case with rubber battery case from aliexpress
(perfine "10000"mah) a 50cm drop cracked the edge of the screen. if that happens, backup your internal memory !!! (just do this on a regular base)
when ur screen gets damaged and u cant enter information or cant see anything anymore on the screen ur internal data is lost. so always have ur internal memory backuped!
and great job LG for producing such a huge pyle of ****. one small drop, screen cracked, bravo, last time i ever bought anything from lg. my V10 dropped like a 1000times, nothing, still up and running. v20, drop, 6weeks later, dead. thanks LG the customers all over the world couldnt wait to use these bull**** crackable glass-screens. great job, -1 customer.
I've tried this on two different computers with two different cables in every USB port on the machines but can't get by the Windows portion. I am using UPPERCUT as the windows box/LGUP reports no device found without it...
Of course UPPERCUT drives windows security mad as it's reported as doing bad things but as I'm using an extra win laptop that will be wiped I disable all of that....
I have three different sourced KDZ files as the one linked wasn't initially reporting any mirrors. Eventually a mirror did pop up for it but by then I had downloaded two others -- all were the same size and one of the three reported from LGUP was bad. Every attempt with the other two failed. Invalid Command response came up a few times... sometimes it just failed at around 80+ percent from the PC side which was 99% on the phone's downloader mode progress bar.
It's very frustrating.... I would like to blame windows but there seem to me plenty here with success... any other ideas?
Also... since it got so far, rebooting at this point just goes to the download mode so I might be hosed... I can force it to the fastboot mode and it is still unlocked so I've been trying to install TWRP onto recovery using the linux/android machine but when I type
fastboot flash recovery twrp.img from the directory where twrp was downloaded I get this:
sending recovery --- okay
writing recovery --- failed remote: unknown command
So... any thoughts?
aloha, at which step are u stuck exactly? did u make your phone being recognized by the win10 pc?
one thing to regard is, that a usb-CHARGING cable possibly wont work, u need a designated media/data-cable.
i had this situation before, where using many different usb cables drove me insane bcuz i simply couldnt establish a proper data connection with phone/pc, it just didnt work. it took me many hours until i realized, that all of the cables i tried were charging cables!
for me the most difficult step was having the phone being recognized by the win-pc, the rest went relatively easy.

The phone is recognized by the PC, no problem. I do have to use UPPERCUT to get LGUP to recognize it though. The step I'm stuck at is applying the downgrade. It gets to various percentages of done-ness and fails. It got far enough that now my only options on the phone are Download mode or fastboot mode. Problem is, I can't seem to get anything to push to recovery so I assume that it's still not properly downgraded.
I've tried a few different cables and keep in mind the cable I used in the linux adb bootloader step worked fine. I don't entirely know what difference there is between a charging and data cable but I do know the main differences in the steps are a> Windows and b> size of transfer.
weird. since im no pro myself, my ideas are limited on this one. there might be some kind of loose contact at the charging port,
that when the phone is moved just a little it looses connection for a second and reconnects again, had that in the past, so try not to touch the phone at all. did u use the 10p kdz file mentioned before? did u make sure it has been downloaded correctly?
if an error occured and there are some % missing... its like faulty ram, hard to detect.
assuming, u did or did not downgrade to 10p, did u try to continue with the linux-step? ---->
---------------------------
on the linux-desktop, click on the LG folder, inside, click on LGLAF runningnaked.
a terminal-window opens.
type: git pull
type: git checkout h918-miscwrte
type: ./step1.sh
now we have flashed twrp onto downloadmode
-----------------------------
maybe uppercut/lgup displayed an error message for no reason, and the downgrade itself went through without a problem in the background.
pcs sometimes do weird things.
if nothing works, try setting up win10 and try on a virgin system. in my case, OnOshutup prevented win10 from recognizing the phone,
or try using a 3rd pc from a friend.
i was able to setup my phone 2/3 using this guide in 30min, no problems at all. (i hope i wrote down, how i solved that simlock issue.....)
no matter what causes the problemin ur case , id be interested to hear what it was.
Thanks! Rooted and Unlocked thanks to this guide!
I tried following other guides using UPPERCUT and it fails to downgrade due to Anti Roll Back. How does this relate to this guide since the last thing I want is for (by design) for it to brick the phone. I have yet to find anything specific saying an unlocked bootloader will bypass the anti rollback check.
Hi As a noob does this keep VoLTE? I have followed this guide and backgrade to 10p was perfect! VoLTE working on a phone that was "new" from china. VoLTE did not work on the 20p rom it had. Also does anyone prefer Phoenix591's h918-20g-prerooted rom to the stock one? I have read a lot but am somewhat confused by varying instruction threads. I want to use this as a daily driver. Thanks

My phone did not want to boot this morning after swapping SIM-cards twice. Tried many things, including a hard reset, but nothing worked; the phone kept getting stuck in the second boot menu (with the fancy coloured X). When I tried to leave it it took a few minutes but the phone finally booted.
But I lost all settings (not files luckily) and came into an unknown screen. Had to setup a Google account but could not do that before accessing for internet. All these things work again, but when I reboot the phone it seems to reset again and I have to start from this unknown screen again.
Does this sound familiar and what can I do about it?
By the way, the phone currently runs Android 2.3.6 so there are no official updates (right?).
I've been messing around a bit and the "unknown screen" seems to be the new initial Android screen, in which you can setup the phone (Google account etc.). Strangely enough the phone keeps resetting and I cannot change anything. Even formatting, either through Windows or the boot/root menu doesn't help: all files that are on the phone right now are kept. I cannot add new files either.

First of all, do you have a Nexus S, or Nexus S 4G? Is your bootloader unlocked? If not then I suggest you follow the guides in the development section. I can't put links due to still being 'new' on here. Find a recovery, flash via fastboot, boot into recovery and flash a rom to your liking. Or you can find some system images and flash via fastboot. I hope this helps. If not, then you can pm me and then I will show you how.

Thanks for your reply. I did not unlock the bootloader. I've seen many difficult topics and don't really know where to start.
I just found out that the phone not necessarily resets to a previous state (this morning) but seems unable to write anymore. I just hooked it on to my PC, removed a file, disconnected, and upon reconnection the file was there again (whereas Windows really removed it).

I am uploading some files to Dropbox now. Its gonna take a bit. Then I will guide you through, step by step. Sorry for the wait. I know you want to get your phone back up and running. In the meantime, I recommend doing some reasearch here on xda. Don't be afraid of Google, either. Google can be your best friend.

Read it first. It might come across tricky or hard, but its not... Once you do that to unlock bootloader and root, I would advise you to download either a stock rom, or any others you may feel comfortable with. Look around. There are plenty here on xda.

Thanks again . A friend of mine was trying to help with bootloading and stuff, but it's somewhat obscure. He said that chances that it's software or hardware are just 50:50.
Got me kinda frustrated yesterday evening but I still have warranty on the phone (have it for half a year now). Problem is that it might be a hassle, because of a conflict between the shop and the provider. But that should work out.
In the meantime it would be nice to try and get it running again.
Strangely enough, the phone drained itself this night. I made a basic install yesterday and left it in standby. This morning, when I checked the phone, it didn't do anything so I thought it finally passed away. Now that it's hooked to my computer it's charging, and it seems to start from 0 (starting with 0 bars of the battery).
Via your link I came to the following guide, which worked partially (cannot link it here).
age tee tee pee ://jaxov.com/2011/02/how-to-root-android-2-3-3-gingerbread-on-nexus-s/
I got up to step 13, where it seems that I cannot find the .zip-file because the phone doesn't store new files...
You can wait for warranty, or you can follow this guide:
http://forum.xda-developers.com/showthread.php?t=947950&highlight=odin
Odin will flash it back to stock without the need to put files on your sd card. Just download the odin files, open up odin, put phone in download mode, and happy flashing. You have to be careful with odin, though. Follow the guide. If you need help, then let me know. I can probably do it remotely for you.
Thanks, I'll try that tomorrow (topic doesn't seem so clear at first glance).
According to this guide, I have to start in Download Mode. I can access this by holding Volume Up + Volume Down and then plugging in the USB cable. It works, but the phone will not be updated and I'm stuck with the "Downloading..." message. Also, Windows Device Manager sees a Gadget Serial, which I cannot update. Google didn't allow for a clear answer (Samsung PC Studio 7 didn't work).
I also think I have an i9023, because it's the European version (which SHOULD be with an LCD screen).
By the way, I just tried formatting through Windows (FAT32) and if still connected the phone indeed seems to be empty. But as soon as I disconnect USB storage all files (on the phone) are back. Nothing special because the problem is very consistent.
Update
Alright, I finally got the drivers properly installed (also to work in Download Mode) and found proper Bootloader/PDA/CSC files (i9023EUR) for Odin and managed to do the flash update (however Odin I used is called I9003_Odin3 v1.82, don't know if that is a problem).
Then I should do a factory wipe, which works (Bootloader -> Recovery -> Wipe), but if I explore the phone I can see that all data is still present (all images, music, etc). So the hard drive still seems fixed.
Please help me out, guys...
Suggestions? Or unfixable and should I send it to be repaired?
I found out that I did not post my last update. I managed to flash with Odin, and I can get into the Bootloader menu to wipe the phone's data. I can, in Recovery Mode, also see the hard drive and it seems to be empty. That is, the phone fails to see it.
When I reboot out of Recovery Mode the phone gets stuck at the Google logo and that's it..
Ok, I will send the phone to be repaired. The phone is now unrooted and does not go further than the Google load screen.
Do you have fastboot? If not then download below.
http://dl.dropbox.com/u/64632729/platform-tools.zip
Extract contents to desktop. Open up a command prompt:
cd Desktop/platform-tools
Put phone in bootloader mode. In command prompt type:
fastboot oem unlock (only if your bootloader is still locked). If its unlocked then download this
http://dl.dropbox.com/u/64632729/recovery-clockwork-5.0.2.0-crespo.img
Put in the platform-tools folder you extracted earlier. Then type in command prompt:
fastboot flash recovery recovery-clockwork-5.0.2.0-crespo.img
Sometimes the flash might say 'fail' if that is the case then just boot the recovery image by typing:
fastboot boot recovery-clockwork-5.0.2.0-crespo.img
Now boot into recovery and flash either a stock rom, stock rooted rom, or whatever your desire is.
This should work. If not, then there has to be a hardware issue with phone and go ahead and send it in for warranty. Let me know if this helps.
Flashing Clockwork did work, but if I understand correctly I have to copy the stock rom to the phone and load it in Recovery Mode? When I connect the phone to my PC it is recognized as an Android Phone (and even as a Nexus S) but the drive it shows up as seems to be recognized as empty ("Please insert a disk into Removable Disk (E.").
So what do I do?
What is sort of promising is that it indeed was capable to flash Clockwork. So the memory is not completely stuck. However, when I do a format, still nothing happens (phone isn't formatted).
Update: I am able to mount the phone to USB and I can access the phone via Windows. However, I can still not format the SD Card (which is of course internal) or put files (stock rom) on it. Are there other tricks to flash a stock rom? If not, it does indeed seem to be that I cannot flash a custom/stock rom because the drive of the Nexus is frozen/broken/whatever.
Hi there,
i have a huge problem. As there was no warrenty left for my One S I thought about to change the firmware to CM11.
I have to admit that i don't have any experience in doing such things, but i thought, it couldnt go wrong if i follow a tutorial.
So at first i unlocked the bootloader via HTC website and istalled TWRP 2.7.1 (latest version). Everything went well, I placed the ROM into the phones root directory, started the recovery and then whiped it before choosing install and selected the file. After about 30 seconds the phone reported the step was successful and i pressed reboot. Then there was the HTC starting screen and then a black screen.
After that i had no reaction but the blinking buttons when i press the power button for a longer time. But it changes nothing. No normal boot. No access to fastboot. Only if i connect it to my PC there is an aditional device to see, but whitout any access.
I know I did wrong but i have no idea what or how to fix it. I hope you can help me.

Now i found a way to get access to fastboot again, but i dont really know what to do now.
Can you give me an detailed tutorial, for jelly bean or kitkat (dont matter) that is surely working now?
My main problem is that i can't copy my files into the root directory as i cant boot the phone.
Does it show up in computer connected devices?
If it does, download stock kernel and ROM and upload to phone and go into recovery[power +volume up while off] and flash them both kernel first.

The problem is the phone wasnt ever shown as device on the pc (like a flash drive) since version 4.1 so I allways needed some tricks like airdroid. So i suppose i need adb commands to copy files and i dont have so much experience in doing this.
Do you know how to use adb?You don't need adb I just wanted to know to see if it shows up there and not on computer you simply need to install the drivers.Try holding down all 3 buttons to see if it powers down. Do what it says http://www.technewscentral.co.uk/enter-fastbootbootloader-mode-htc-one/id_7930 if works go into fast boot. Does it say locked or unlocked. If unlocked go herehttps://github.com/koush/UniversalAdbDriver and get the windows installer if your on windows.

I now found out how adb and fastboot are working, but the main problem now is, that it says the sdcard cant be mounted. I tried this tutorial http://forum.xda-developers.com/showthread.php?p=25557817#post25850720 but i dont know how to do the first step. Du i need an extra file and where do i get it from and how to use it. As long as i dont get back this access, i couldnt install any OS. I tried also sideload. It was able to copy but cant install because of the missing sdcard access.
I hope you can help me to become my phone running again.
Go here http://m.youtube.com/watch?v=xWmnHwkDrKk but first type adb devices in cmd. If it shows ur HTC type adb shell and and type mount sdcard next to the "#" once it appears although you should be using the fastboot shell not adb commands.adb should only work on a powered on device or you can use fast boot in cmd while phone is in fastboot not recovery(you did say the phone can go into fast boot right?). Just make sure you got the right drivers and both fast boot and adb. You should get Koush's Universal drivers from my previous post since some phones have multiple drivers and MAY cause problems with cmd. Also HTC one S doesn't have expandable storage correct?

Wow. Now I incidentally soft bricked my phone again if you would believe it and nothing works this time.
Have you been able to fix?
Sent from my ZTE_N9511
Okay, i forgot to write but adb and fastboot are working on my Mac. I use the Mac because Win 8.1 has the known driver problems.
I tried a lot now, but i recognized maybe the main problem. My phone is still S-ON in bootloader. For sure thats the problem. Do I need to get rid of it and how do I do. The tutorial i used hasn't mentioned this step, maybe the person was still S-OFF.
The first thing i try now is to flash the original recovery, lock the bootloader and execute the original signed RUU to get back the original software first. Im going on holiday on tuesday and it would be a pitty without the phone. When I get it working i will leave it, and thy it again, when I'm back. Otherwise.......****
Use this tutorialhttp://htc-one.wonderhowto.com/how-to/fix-soft-bricked-htc-one-by-flashing-new-rom-via-adb-0154361/unless its the one you used already. From boot loader you were supposed to have gone to fastboot.boot loader has to be unlocked.From fast boot you flash TWRP.IMG which happens to have a special adb side load feature under advanced options. There you upload another ROM and kernel.here is the full list of supported devices as I don't know what variant or carrier you havehttp://teamw.in/twrp_view_all_devicesAlso, a stock kernel is optional but it always seems to fix my problems.
Sent from my ZTE_N9511
Thank you. But I already did it like this. The issue is, than after using sideload successfully the installation fails because of the known "unable to mount storage" text. And i don't know what to do wrong.
Like I already said, my phone is still S-ON, but can this make a difference?
Now i got it to bring the stock ROM running again, and as I'm on holiday for a few days I'm happy it is working again.
But one thing is left. It seems like there is no 3G/HSDPA connection now, only EDGE. I dont know what went wrong. Did you hear about this problem.
By the way, my phone is the standalone version whithout any provider.
Search the forums about edge only. There is a huge thread on this.
I tried rooting the phone and attempted to get twrp on there using one of those apps (believe it was called RashR) and when it rebooted, I was getting an error screen and in this "dload mode" it stated The phone would keep booting up into this screen and I don't think you could push anything via adb when connecting your computer to it.

Try holding the power, volume up, and volume down buttons all at once with the cable disconnected. Might need to try this a few times as it doesn't go into download mode every time.

I just went through this after being without my G2 for nearly a year. Luckily, I had other devices but still; I really like my D801. Anyway, I'd flashed a bad bumped bootloader that landed me in "Demigod Mode"; didn't have a PC until I fixed mine this week, and was determined to get the LG up and running. I tried different versions of flash tools, LG's Mobile Support & PC suite, fumbled with the drivers, which in the end is key!
If you're connecting your device to your PC and see QSUSB_BULK as one of the attached devices in Device Manager - assuming you're using a Windows PC - you need the SRK Tool found here:
http://forum.xda-developers.com/lg-g2/general/choise-unbrick-qhsusbbulk-qualcomm-9006-t3093844 because it's likely - as in my case - all your device's partitions have been nuked and you won't be able to get into download mode no matter which combination of key presses you try. Follow @somboons guide. Use his thoroughly amazing, brilliant SRK Tool. He's the real demigod when it comes to LG devices and his tool couldn't be any easier to use. He's done all the hard work, gathering the different partition maps for just about every LG device in existence and I swear by it since my D801 is up and rocking and only because I never gave up.
There are truly gifted people here on XDA that deserve our profuse thanks and so much more for all they do for this community. The task - and the tool - may seem daunting at first, but you'll find it really couldn't have been made any easier so do give it a try.
I mean no disrespect to the OP, but this is what worked for me and I felt it important enough to share for others going through the same situation.
We have the same phone, maybe different revisions (30b ? Mine is 30c). Encountered the same problem. The phone isn't really "bricked". You should still be able to boot normally. It's just the recovery that's trashed.
I induced this problem by running Flashify while SuperSU 2.65 was misconfigured. Flashify will gleefully go about it's business even though SuperSU may be misconfigured.
Here's the fix:
1. Don't use Flashify (or similar tools), prepare to install TWRP via Autorec. This will install TWRP 2.8.6 which is a fairly current version.
2. Under SuperSU 2.65 settings uncheck the "Mount Namespace Separation" box and reboot.
3. Now run Autorec. TWRP will be installed without any problems. I recommend QuickBoot to conveniently boot the TWRP recovery.
This is the shortest path to getting TWRP installed. Its big advantage is that you don't have to explicitly muck around with unlocking the bootloader, Autorec takes care of that for you behind the scenes (via the Loki patch). The author of Autorec cited a problem with Autorec not running in the presence of SuperSU 2.6x. That isn't true, it's simply the settings change I pointed out above. I have contacted the Autorec author about this, he agrees with me, and hopefully will update the Playstore Autorec description as his SuperSU 2.6x warning is creating a lot of unnecessary confusion and misunderstanding.
Enjoy TWRP. I look forward to checking out the CM ROM.
cheers.
This worked for me, great!
Thank you

Thank you for offering this, but my G2's gone .-.
Now I'm happy with a G4 (For now, hopefully bootloop wont get to me )
I'm going to try and encapsulate everything that's going on into this initial thread but I'm sure I'll miss something.
Basically, I undertook to root my phone last night. I followed all the steps in the root thread, and I thought it worked, but then when I went to the root checker to see if I was successful. The test couldn't get a result the first time, and then failed the second time. I've known my phone to be a little temperamental when it comes to stuff like that, so I shrugged it off. Then, everything started running with so much lag that my only option was a reboot. It came back up just fine, but then, apps wouldn't open anymore. Since a reboot fixes everything, I rebooted AGAIN... except no I didn't, because I couldn't move past the white splash screen.
After some time hacking around with TWRP, system restoring my phone and the like, I finally managed to actually load the OS again. I think the phone was rooted at that time, but I don't know for sure, because this was the drawback: I couldn't install ANYTHING. My idea is that the system was rebooted into read-only mode. I tried everything I could think of to revert the system to rewriteable again, but nothing ever panned out. There was just one thing that stood out to me: "Your phone worked properly when it wasn't rooted." So, I got the brilliant idea to use SuperSU to unroot my phone. Stupid, stupid move, because now my phone can't boot past the white splash screen again. As a last ditch effort, I decided that it was time to flash the stock system to the phone. Except I probably did it wrong.
Code:
fastboot flash recovery recovery.img
Code:
fastboot flash recovery system.img
Code:
fastboot flash recovery boot.img
And where I stand now is that my phone will not boot past the white splash screen, and I can no longer access either TWRP or Fastboot.
Is my phone fooked, or can anyone save this?
#1 You can't flash system image via fastboot - it's semi-locked.
#2 You can't use 'flash recovery' command for boot and system images.
#3 For restoring your phone use SP Flash Tool - there's a thread in the General section called 'How to unbrick'.
Try it and let us know.
Cheers
Yeah, I realized afterward that if I were trying to flash the image of the system, I should not have used the "flash recovery" command because I disabled access to the other recoveries, lol. I have tried to use the SP Flash Tool in the past few days, but I could never get any download progress. I think my computer isn't making the VCOM drivers accessible to be able to flash those things to my phone. Do you have any advice on that end? Because I have seen that thread and tried those steps but I'm just not successful.
You should also read all replies to this thread - there are people who solved their problems with SPFT in their own way, that's how I've revived my phone from hardbrick.
Make sure you're phone is disconnected when you start the flash. AFTER you hit the download button in SPFT... then connect your phone...
Fantastic advice from both of you. I'm ready to revive my phone!
Okay, I think I'm making good progress on recovering my phone. I have managed to get back the stock recovery onto my phone, which I then used to install TWRP. But I'm not out of the woods yet. I used fastboot to flash the boot image onto my phone also, but when it came to the system image, I'm having a lot of trouble. The only ROM I can find for the Blu Pure XL is a 7z file. Now, I know how those work, I have 7zip and I extracted it for the system image. When fastboot was available to me, I couldn't push the system image to the phone. Now that I have TWRP and I have no more access to fastboot, I've tried to load the system file onto my phone through my SD card in four different ways:
As a .img file
As a .7z file
As a .zip file that I created by zipping up the image file
As a .zip file that was .7z, but I changed the extension
None of those methods worked. The Blu development thread doesn't point me to a zipped ROM file. One person there said that they had a backup of their files and provided a link, but those images seem to have been removed.
I'm so close, I can see this phone working again in the near future, I just need your help to get me there. Please! :'(
Edit: Also, keep in mind, I'm dumb. I don't think I really did anything super wrong, but I may be missing something ultra obvious. So if you could just keep your answers dumb for me, it would help even more.
I would stop trying to use all of the methods you are using I believe you are slightly confused by them at this time..
At this point what you have done with the random image flashing is get damaged partitions..
Get SPFT. Turn off you phone completely.
Download the full Scatter file for you phone. (put it aside).
Download a file called ALL MTK driver install. ( or something to that effect). Search for it on Google. You will find it. Run it and then reboot your PC completely.. (if you have windows 8 or higher look online on how to install unsigned drivers) --THIS IS THR BIGGEST PROBLEM PEOPLE HAVE--
Extract your full downloaded scatter image to a directory.. (you can download the Gionee E8 image if you want) it is what I am running on my Blu..
Run SPFD read the thread that they pointed out to you. Find the scatter and point SPFD.. Once it is loaded on the program UNCHECK the PRELOADER check box.. (if not you can cause problems) ..
click download and after 10 seconds or so plug in (you completely powered off) phone into the computer..
.Then wait..... and wait... It will tell you it's progress..
Keep trying it, it WILL work.. and ALWAYS unchecked preloaded when flashing with spdf...
I did follow all the steps in the original guide, and I followed the steps that you gave me too, down to using the advanced device manager to remove any MediaTek drivers from the computer and restarting the computer with disabling the driver signature verification, but when I click download, wait, and plug my phone into the computer, just nothing happens. The computer says it's an unrecognized device, and the download never progresses.
I see also that you said keep trying, but every time I try the SPFT, it never sends anything to my phone. And I don't even know how to tell if I'm missing some important step.
OK this happens sometimes. plug the phone in with device manager open.. plug the phone in when it is off..
When it says unrecognized device double click on it really fast( it will disappear fast, try it a couple of times if you don't get it the first time) then hit update driver.. point it to the MTK drivers folder (unzip the MTK drivers folder). It will pick the proper driver. on some computers it loads up so fast it has no time to recognize the driver..
After you load the drivers power off your phone again and follow the instruction I gave.. After you do this once it will load the drivers right after this..
When I double click on the unrecognized device button, it just brings up a notification that my device wasn't recognized because it malfunctioned. I don't have an option to install any drivers.
My problem is finally solved. After starting up SPFT and clicking download, I held Vol - and Power and then connected it, and that pushed the download forward. I got to the Blu animation screen, and it stayed up FOREVER, but then the next time I looked over, it was on the initial setup screen. Good as new.
Thank you guys for all your help. This forum really is an amazing place.
Good evening folks. Over the Past week, for some reason, people who downloaded the new Samsung update for A51 have had their phones bricked. FOR SOME REASON, this seems to only be happening here in South Australia. I haven't seen anywhere reporting on this issue other than local news. I have had three A51 phones come into my IT store, all with the same problem.
here is a link to one article talking about it: https://7news.com.au/technology/sam...ng-priceless-photos-vital-contacts--c-9340963
Upon installing the update, their phone will restart then it will not progress past the SAMSUNG logo. I have been able to get each and every phone into recovery mode however I when I try and reboot the phones into bootloader, they simply say "entering fast boot" and then don't progress any further.
Since I have been unable to boot the phone to bootloader I don't have many solutions in front of me, I can either factory reset the phone which has been proven to work, or I can try some alternative method. Simply put, I refuse to take the simple way out and simply factory reset the phone, I don't want my customers to go through the trouble of losing their photos.
The only real option I see is using ADB to install either a new update or new firmware, however, I have had ALOT of trouble finding the necessary software. I have been able to get ADB to detect the devices with a USB connection, so I tried installing some firmware, I found for my device. I didn't trust that this was the correct software, but it couldn't hurt to see if it worked.
Using a515fxxu5gvk6, I was able to find a website where I could download Firmware https://samfw.com/firmware/SM-A515F/TEL I don't believe this to have the correct software but it was the only option I could find that didn't require money or an account.
upon extracting the zip file and typing ADB sideload <file name> it would start the process of installing the software however, it would only install for a single second and then stop working. I would be greeted with the messages: "footer is wrong", "update package took 0.3s", and "signature failed". I believe this means I have either grabbed the wrong software or I have tried installing the software wrong
I really don't know where to find the correct software, and I don't even know if I will be able to update the phone using ADB since I never was able to enable developer tools.
I have already spent quite a few hours on this, and it's starting to drive me insane. I have gone down so many rabbit holes researching different options only to come back up empty-handed. Im lost and really don't know where to turn.
any help would be literally amazing, if someone could even point me in the right direction that's all I need. even if you tell me there is nothing that can be done and I need to factory reset the phone I can at least go to sleep knowing I god damn tried.
Well, one thing you should know is that Samsung doesn't use fastboot to flash software like many other brands. It's unfortunate to say that a lot of the guides you read online are just copy-paste of guides that do use fastboot. Adb doesn't really flash software without elevated permissions afaik.
You can flash firmware using Odin for Samsung devices. There should be plenty of guides online on how to use it, your main goal right now is figuring out how to boot into download mode for Samsung.
What I would do is try to turn the phone off completely if you've been able to boot to recovery. After that, hold both the volume buttons and while you're holding them, connect your phone to a PC. This should force the phone to boot to download mode. Read the screen as it may ask you to press VOL + to proceed.
After that, you can flash the files
AP_XXXX
BL_XXXX
CP_XXXX
HOME_CSC_XXXX (Use HOME_CSC instead of CSC_ so that the phones don't lose any data)
And after that, you should be able to flash firmware

Thank you so much for your reply. I have spent the past few hours setting up Odin and installing the firmware.
I have run into another problem, I select all the firmware I wish to install then click start. It loads for two seconds then says "PASS!". However the phone is still stuck in a boot loop
I believe this is because I haven't turned in USB debugging, since I can't get into the phone I can't turn it on even if I want to.
Is there another option?
USB debugging isn't needed when flashing through Odin. You're most likely just missing the Samsung dev drivers. Try and installing them: https://developer.samsung.com/android-usb-driver
