[Q] e977 without any rom to flash inside sdcard - LG Optimus G (International)

Hi i follow some tutorials from youtube teaching how root my rom stock, flash a custom recovery and install cm12.1.
i used the FreeGee.apk to install the TWRP recovery. A was going to flash the cm12.1(for the e975, yes in a lot of tutorials it works ) but it fails, get a error i dont know why.
I try to wipe cache and dalvik cache like the tutorial, but unfornally i wipe all sdcard.
So, a dont have the stock rom, dont have the zip to flash a new rom.
I cant mount the mtp in this TWRP 2.6.1 recovery that free gee installs.
I cant use fastboot too, I type fastboot device and none.
I try a lot of drivers and windows 10 and 7. nothing.
can a good soul help me?
obs.: idk if it is normal, but in the bootloader screen it shows device -mako, variant - mako 32gb

Do you have a Error with the cm-12.1 zip in recovery?... It is happening to me too...
I had to flash cm12-20140416 zip file...
Remember Factory Reset, Cche and dalvik format

[Q] help flashing MIUI, my first rom flash

hi
i already unlock the bootloader, install custom recovery TWRP, and done a backup
i also copy my backup to PC
now i'm confuse
- i need to root the phone or can i just flash the new room?
- if i need to root the phone i found an italian guide on 4.0 and attach file, can i use that? i have 4.1.1 on mine now
i'm not interested to have HTC stock with root but what i want is to install MIUI ROM
this is the only guide i found in english that explains how to install the rom
external link (i can't post it) miuiandroid.com/community/threads/installing-the-htc-one-x-required-s-on-steps.16592/
what i understand is:
- boot my device power + menu down, to see the FASTBOOT USB i have to select FASTBOOT
- flash the boot.img
- press the power button once (HBOOT i guess), click volume down, highlight recovery & press power
- Flash the downloaded ROM via recovery normally and it followup at this link
external link (i can't post it) miuiandroid.com/community/threads/how-to-update-upgrade-miui.15424/
i need to copy the img rom in SD ROOT before starting with all this process
- now i need to Wipe data/factory reset, Cache Wipe & Dalvik Cache Wipe in all tutorial i found this is done with clockworkmod
in TWRP under menu WIPE i guess are System, Cache, Dalvik buttons
after that i'm note sure if i need to flash italian language, if i don't need and i can just download it later i tihink is not a big deal
unless is all in chinese
is the metod correct?
do i have to copy ROM file in .zip format as i download?
here where i found ROM
from official site grey button miui.com/download-7.html
OR
from UK web site miuiandroid.com/community/threads/3-4-28.20232/
the boot.img is here
point 3 miuiandroid.com/community/threads/installing-the-htc-one-x-required-s-on-steps.16592/
i'm not sure if would be better to use clockworkmod, since most tutorials use that..
thanks
Doesn't matter which recovery you use. Yes just place the zip file on your sd card. Flash boot.img as you already said. Perform a full wipe and then flash the Rom zip. Reboot and its done.
The Roms are pre-rooted so you dont need to worry about that. Italian language should be included i guess.
Sent from my HTC One X using xda app-developers app
Heres what i do :
1) Put Rom.zip on SD card
2) Put boot.img in fastboot folder
3) fastboot erase cache
4) fastboot flash boot boot.img
5) fastboot erase cache
6) Reboot into recovery
7) Full wipe (except sd card)
8) Install rom
9) Enjoy new rom

i did my first mess but fortunally i could restore since i had copy the backup on my mac too
i don't know what went wrong but this is what happened:
- i did how was told before, but actually i download boot.img and rom from 2 different sites
- after reboot it didn't move from first screena waited for 15 minutes almost, so i did reboot in recovery tri to wipe but nothing happened
- so i decide to restore... but it did boot even if it was successful
- i thought that if i flashed the boot.img first time i may need to do it again, i found boot.emmc.win, rename it to boot.img, flash it and then i restored successfully
:victory:
now, to try a different rom i need to restore (maybe is safer)? can i copy the rom from recovery or fastboot?
what can it be wrong with my miui rom? could it be boot.img and rom file mismatch? can't find where to download both

i would try a different rom for now, viperx perhaps. and the boot image is in the rom zip, extract the boot img from the rom and put it in your fastboot folder then copy the rom to your sdcard. once you have done that, fastboot erase cache, flash the boot image, fastboot erase cache again, then back into recovery, wipe cache and dalvik just to be sure then use recovery to flash the rom and hey presto. all of the above is assuming you have the one x international tegra 3
I have htc one x european terga 3, as far as I know mini is only for tegra 3
what you describe is exactly what I did:
- I leave the rom zip ad it is, I didn't remove boot.imf that I extract, correct?
- when I flash I hit hoot fastboot, connect USB and fastboot change in fastboot USB, to go back I select Hboot and and hit power, prom there recovery
- I did unlock bootloader but did not get rooted my phone, could it be that?

read this post. at least twice!! http://forum.xda-developers.com/showthread.php?t=2069904 do not do the "unlock bootloader" section as you already did that
@nogotaclue sorry i read so many, and some of them sayed that root was not necessary if you flash a new rom, other sayed it could still be necessary... now i rooted with the app and did a new backup that i'm coping on PC
reading further it says: to wipe, install rom, and flash boot.img after
"Now go back and press install. Go to the folder where the ROM you downloaded, is located in. Select the ROM and slide the screen to flash it. After it flashes, press the back button. Press Reboot and Reboot into bootloader. Open the ROM you downloaded from your computer. You should see boot.img. Extract it to your computer. Open my toolkit and press Flash a Kernel. Locate the boot.img and it will flash it."

yes you can do it that way, i usually flash first but sometimes it does not work, so just flash it last as it says in the tutorial
after root, with the same steps, the ROM starts... but
touch screen is not working :crying:

[Q] No network connection???

Ive got an international HOX and im currently running CyanogenMod 10.1.0-RC1 and i was thinking of going over to a SlimBean rom. it seemed really simple, just transfer the ROM.zip file and the GAPPS.zip file to the SD, boot into recovery and install (i thought you needed to flash the boot.img ... anyway, i was following the tutorial so i didnt) so i did all of that and it all seemed to be working fine, apart from that i couldnt connect to WiFi or a mobile network. any ideas??
Did you flashed the boot.img later on ? Can't really get it out of the text now
Steps
Flash the boot.img
Make a full wipe
Install slimbean
Install gapps
Reboot
no, it specifically said not to extract it from the ROM.zip
Do this :
Go to the thread and head on to post 2. Download the boot.img and modules from NEO
Flash that boot.img and go to the recovery and mount the sdcard, copy the modules.zip to it. Unmount and wipe cache partition and the dalvik cache. Then install the modules.zip and reboot
cheers. you seem to sort out all of my issues
yeah well somebody has got to do it hahah

HTC One X Bricked.. Help Needed

First of all, I want to tell that I am a beginner and do not know much about rooting and custom ROM installation.
Few days back, I became very keen to know what is custom ROM and is there any custom ROM available for my HTC One X. I searched through internet and found one, downloaded it. Rooted my phone, Unlocked bootloader. After that I installed CWM touch recovery. Everything was going great. Then, I first flashed the kernel given along with that custom ROM. it Flashed. Then, I flashed that Custom ROM. I Showed an error. I flashed it twice or thrice but it stucked on that error. Also in a Hurry, or Excitement, I forgot to take a backup of my previous ROM. After that, I switched on my phone it does nothing and stucked at HTC Bootscreen. I factory reset my phone, it wiped all data from phone. I Thought, a RUU would work, but it also doesn't worked.
I went to HTC Service Center, they are saying that motherboard will be replaced, which is almost of same cost of phone. I cannot spend so much.
I tried so many ways, but nothing worked.
So, I am Finally here seeking help from Experts. Any help will be highly appreciable.
Sorry for my bad English.

Try this, flash this recovery :

Make a full wipe and install the rom.zip. and flash the boot.img from the rom.zip
What rom were you trying to flash ?
If its a kitkat ROM you can't use cwm recovery to flash that rom.. you either use philz recovery given by mr hofs or latest twrp recovery from the twrp thread or indexed listing thread..

sorry for this stupid question. But how to use ADB Sideload..??
Just mount the sdcard in the mounts and storage menu ! No need for adb sideload
And don't just install the rom, you must perform a full wipe before that !
Factory reset
Wipe cache partition
Wipe dalvik cache
Format system
Format data
Format cache
Then install the rom !

If that doesn't work try this , this is what I did when I bricked my HTC One X:
1. Download Fastboot
2. Download adb
3. Download cm-10.2.1-endeavoru.zip (https://download.cyanogenmod.org/?device=endeavoru)
(I used this one , it's justs so you get your SD Card Working again and you can
put ROMS and everything on it again)
4. Download openrecovery-twrp-2.4.0.0-endeavoru-JB (http://techerrata.com/browse/twrp2/endeavoru)
(This one will be used because it has touch ability's and you can install ROMS with it )
4.1 Or you can download recovery-clockwork-touch-6.0.4.7-endeavoru.img (a.k.a Philz recovery)
(This one will be used because it has touch ability's and you can install ROMS with it )
( I used Philz recovery 5.15.9.img (provided by Mr Hofs -> who is a great guy btw)
5. Download openrecovery-twrp-endeavoru-2.1.7 (http://techerrata.com/browse/twrp2/endeavoru
(This one will be used for adb push commands, openrecovery-twrp-endeavoru-2.1.7 has a built
in ability for your sd-Card , adb can recoginze it but the problem is your touch will not work.)
6. Go into bootloader -> fastboot and do this:
6.1 fastboot flash recovery openrecovery-twrp-endeavoru-2.1.7.img
7. Go into recovery (Hboot -> recovery)
7.1 just open the recovery, your touch will probably not work. DONT LOCK IT JUST LEAVE IT OPEN
(ADB sideload didn't work for me so that's why we are going to do this)
IF YOUR TOUCH WORKS YOU CAN SKIP STEP 8
7.2 do this command: adb devices
If you don't find your devices in this then the next steps will not work.
YOU HAVE TO SEE YOUR DEVICE
7.3 do this command: adb push cm-10.2.1-endeavoru.zip /sdcard/
You can only do cm-10.2.1-endeavoru.zip if the zip file is located in the same folder your using
with command. I'm not sure about /sdcard/ . I cant remember anymore But this will put the
but this will put the zip Directly on your SDcard.
8. Go to bootloader -> fastboot
8.1 do this command: fastboot flash recovery openrecovery-twrp-2.4.0.0-endeavoru-JB.img
8.2 or do this command: fastboot flash recovery Philz recovery 5.15.9.img
Your touch wasn't working but it will work now.
9. Go to booloader -> fastboot
9.1 extract the boot.img from the Download cm-10.2.1-endeavoru.zip into the fastboot folder
9.2 do this command fastboot flash boot boot.img
9.3 fastboot erase cache
10. Go back to recovery
10.1 Wipe User Data
10.2 Wipe data cache
10.3 Go to advanced -> wipe Dalvik Cache
11. Install zip from sdcard
11.1 Choose cm-10.2.1-endeavoru.img
11.2 Install the zip WITH full wipe
12. After the install, reboot. You should have a full functional HTC ONE X now
13. Now but your ROM's(ZIP FILES)/Recovery(ZIP FILES)/Kernels and everything you want on your HTC because
You can see your HTC on your PC again!
I tried adb push.. But i cant find the pushed zip on sd card in recovery.. Moreover i tried flashing using fastboot command i.e. fastboot flash zip rom.zip it ended with an error <remote not allowed>

For maximus hd do this :

Mi 9 SE in boot loop after rom flash

dear all, after flashing Xiaomi.eu 20.3.19 update I am stuck in a bootloop to the recovey or to the boot loader.
after the second attempt to flash the zip file I was not able to enter my my so the interal sd card is vlocked.
I have access to the otg drive but.
I tried additional the following:
Format data, caches and system
Install 20.3.19 via OTG
install 20.3-12 via otg
install fresh magisk 20.3 via TWRP
updarde to the newest TWRP
downgrade to an older TWRP
all without success
Does anybody have an idea to solve this issue?
Thanks in advance
If you want to flash xiaomi.eu you shouldn't wipe system when flashing from miui. It won't boot if you wipe system. So now you must flash miui with miflash. Then twrp and xiaomi.eu (wipe cache, dalvick)
Thanks alot for the swift reply.
This is the first time that I had this issue and now I am totally stuck, is there no other way than mi flash?
If I well remember flashing the factor< image will erase everything?
I made a backup but due to the locked internal sd card I have not access on this data.
Thanks for the support
Now I have another problem,
As soon as I start the Mi flash tool or the Mi unlock tool the device shuts down from bootloader mode.
I´m Stuck
Thanks for support
Maybe you have some driver problems?
@baltes: ...or try another cable or another USB-port
Thank a lot,
Ich changed the cable and the USB port as well. No change
I downloaded the standard ADB and Fastboot drivers ver 1.4.3.
I don´t hope the the devise is not toally bricked
@baltes: uninstall ADB/fastboot, Mi tools and Mi drivers. Reboot, install MiFlash again and let it install the needed drivers.

Thanks,
I uninstalled everything, and reinstalled miflashtool, no change as soon as I select refresh the 9SE shuts down (from bootloader)
I managed to erase the internal storage in TWRP, Im able now toto copy MIUI zip on the interal storage and install it successfully. but reboot is then still again innTWRP
So flash some aosp based Rom. Wipe cache, dalvick, data and system before. Do not flash magisk or other mods. Just Rom and gapps. That kind of Rom should boot. Then you can try flash latest global miui Android 10 with miflash and start over to xiaomi.eu.
@baltes: I wouldn't use AOSP to get MiUI runnable. If you do so,
* format data
* reboot to recovery
* wipe system, vendor, data, both caches
* flash ROM, no GApps
Better make a clean base by MiFlash: now you first say, that Fastboot only aborts when clicking Refresh. I don't remember this tool, but are there other options besides Refresh?

Question Cannot flash TWRP from Fastboot, TWRP reboot shows Slot A/B, dont know what to do

Ive already flashed a few phones, but this is the first time that Ive got CMD error "FAILED (remote: (recovery_a) No such partition)". So I booted twrp.img, falshed ArrowOS and TWRP from within TWRP and it said something about Slot A and B, which I dont understand ... some guide also said to Format Data, which I did, and then I just could boot into TWRP in Slot A, and no OS on Slot B, which rebooted me into Slot A. I couldnt find any info about this and I dont know what to do. Anybody knows how to properly flash TWRP and custom ROMs please ?
Start fresh by flashing stock MIUI rom through fastboot and proceed from there
1 Boot once into MIUI and reboot into fastboot
2 fastboot boot twrp.img (from platform tools folder)
3 Flash custom rom like ArrowsOS with inject twrp option checked
4 Reboot recovery
5 Format Data by typing "yes"
6 Reboot to system
7 Done
Follow the TWRP install instructions by fastboot boot TWRP.img
advanced, install TWRP
It should then reboot and TWRP will be installed
Then proceed as above by flashing a ROM e.g ArrowOS with TWRP inject.
Then reboot TWRP and wipe data
Use "fastboot boot TWRP.img" to temporarily boot TWRP.
You can install TWRP by using "Install to Ramdisk" inside TWRP and selecting TWRP.img

well Iam still confused about that Slot A/B thing, but since Ive probably bricked my phone, I flashed the fastboot ROM through MiFlasher and I havent tried flashing TWRP or custom ROM since, there are some things I really like about MIUI so Iam gonna see which ROM Iam gonna choose in the future

Slot A and B refer to Project Treble, where there are 2 separate partitions. 1 for OEM like Samsung and other for core Android OS. That way Google can update the OS partition with security updates without having to wait for Samsung to implement those security update into their version of Android, as was the case before Galaxy S9. Needless to say, this way security updates get pushed out way faster, because there is no need to wait an entire year (I'm looking at you Samsung) for OEM to finally implement it. Hope this clears things up for you.

there is a slight problem with this ... I cannot upload any file to the phone, because I have wiped Data, so there is no folder that I can access from the PC, so I can only sideload .zip files, and most of the .zip files just doesnt work for some reason, only ArrowOS, but not the PixelExtended, nor CrDroid ... I cannot even sideload TWRP.img to install it into ramdisk
EDIT: after sideloading ArrowOS and booting TWRP using "fastboot boot twrp.img", I can access internal storage, so I uploaded twrp.img into /sdcard/Download folder, installed it into ramdisk, rebooted to Recovery and now successfully flashing CrDroid ROM that I uploaded to /sdcard/Download

You can adb transfer files in TWRP. You could also use a USB stick connected via OTG cable

how exactly should I proceed ? flash fastboot stock ROM with MiFlasher, boot into bootloader, boot twrp.img, wipe data, and then what ? which slot do I choose ? should I install TWRP into ramdisk, reboot into recovery and then flash custom ROM ?

in case of flashing custom ROM, are the steps same ? just instead of Xiaomi.eu ROM I flash PE, or CrDroid ? and should I format data and dalvik also or wipe data (that option where I need to type YES) ? Ive found official guide for flashing CrDroid, but Iam stuck st booting animation for 30 minutes

Doesn't matter. Just select format data > yes > reboot to system
