I made a boo boo...
I wanted to try a different Rom, instead of installing firmware I installed the Chinese miui Rom in twrp, hit reboot and realised I'd just overwritten twrp with the mini recovery.
I have everything on a USB otg that I need but I've no idea how to get twrp back without the use of a pc. I won't have pc access until monday, is it possible to change recovery without a pc? The recovery now is also not in English, I'm not even sure how to change it to English?
Without root access, you can't flash a custom recovery in system...
"Official TWRP App" in Google Play can flash any recovery image if rooted.
is there anyway to root from the china rom?

Without TWRP or a computer, no you can't...
What about using another phone or tablet?
No, although if you have tablet with Windows (not arm) you can
No just an android tablet. I guess ill just have to wait until I get home this evening and do it from the pc

So I got root on the phone and installed recovery (twrp). Everything seemed to work fine. I put CM on the root and did the factory reset and wipe. When I tried to install it, it said it failed. Now I cant do anything but go to recovery. When I connect it to my computer, it makes the connect sound but doesnt show up in explorer.
Just wondering if anyone can help my. Ideally I would like to flash a rom (doesnt matter which) just to get an OS back.
I tried adb, it doesnt show up in the devices list and cant use sideload (just says starting but never does.

Do you have a back up you can flash too? That's a stupid question ( obviously you don't since your asking for an OS)
Are your adb drivers installed at all. Try download mode volume plus and power I believe.
Secondly what is the error. Error 7?
Corrsea's solution for error 7
Status 7 error means the rom developer is still using the old update binary script.
If you flash the latest philz recovery before you install a zip untick the setting that says" don't allow old update binary" Your zips should then flash without issue.
A better solution is to use the new update binary script yourself or ask the rom developer to update it.
Which you would have to flash from fastboot.
Make sure your adb drivers are installed though.
Sideload newer twrp, flash rom.

I installed a custom rom, decided I wanted to go back to stock by restoring from TWRP, now in bootloop. I can boot into recovery and bootloader via the phone but my PC does not recognise that it is connected via bootloader. Is there a way I can rescue my device?
I have build B29M, and noticed there is a zip version of another build on this forum which I could have installed through TWRP, but would that make things worse?
Thanks for any advice..
Stupid question probably, as you've already installed a custom ROM, but you do have the fastboot drivers installed on your PC?
Yes it all worked before, I think it's because the phone must have defaulted back to not being in Debugging mode, and I can't access the OS to enable this mode.

Well, if you can reach recovery, flash another custom ROM to get the phone usable, then flash back to stock, looking at points 11 and 12.
I managed to fix it, for anyone who may encounter similar issue in the future...I tried restore again from TWRP but this time did not select Vendor Image, only Vendor.
I have this same problem, my PC doesn't see the phone when I go to bootloader and I can't fastboot at all. I can use my phone regularly copy files over. I already flashed to a new ROM from cataclysm to purenexus but still can't fastboot.

hello guys,
is there any custom frimeware for the galaxy grand prime sm-g532f ? i looked everywhere but can't find one.
i need one because there is no more space in my phone, the system took almost everything, 6.5go of the 8 availble, so i can't install big apps even with an sd card ! any solution ?
i was about to install a stock rom, but someone told me that it will take the same space as my current rom .
thank you.
I don't think any developer is interested in this device, it could be due to non-availability of unlocked bootloader, firmware sources, etc. I am thinking of getting rid of mine and move to another device that supports open hardware/software.
In possible solution if you managed to root it the use system app remover to get rid of Samsung bloat.
Good luck.

All phones when you unbox are on factory ROM (aka stock ROM). I think you are referring to rooting and installing custom recovery, I failed and phone always go into boot-loop making me to re-flash stock boot and recovery images.

Please post your results, I am hopeless with this severely bloated device.
Update:
Managed to root using TWRP.
1. Install TWRP recovery.img using ODIN (Windows) or Heimdall (Linux) including SU. Details in this thread:
https://forum.xda-developers.com/ga...overy-twrp-3-1-0-1-samsung-galaxy-j2-t3616589
Reboot to TWRP > format Data partition > while you are connected to PC > copy SU.zip to data and flash it.
2. Get SU.zip from here;

i didn't have a lot of time these days to search for a working "rooting methode", so thank you very much.
I want to make a clean Install of factory image (Android 8.0 Oct) on my Nexus 6P with TWRP.
Should wipe Dalvik, Data, System and Internal storage, then move the stock zip file (That I downloaded from google's web) from my computer to my phone and just install in TWRP? Will it work?
Device is unrooted, only has an open boot loader, I just want to make a clean install of Android 8.0
If you wipe your internal all your downloads and your factory image are gone.
Sure you can flash the unpacked *.img with twrp, but don't try to flash the bootloader or radio with twrp.
If you really want a clean start and wipe everything, then you should flash the factory image with fastboot. This will update your bootloader and radio too.

Hi coremania, I have a few questions towards this method.
1. If the stock image is stored in either external SD card OR USB OTG, even then will there be any problem installing the the stock rom back using TWRP?
2. If the boot loader is unlocked, should one has to re-lock it first before reinstalling the stock rom either thru' TWRP or thru' Fasboot commands?. and finally,
3. Is it not advisable to flash the stock rom from the full factory image using TWRP rather than Fastboot?
(As I think it is easier to flash thru TWRP than typing those ADB commands in Fastboot).
Thank you for your inputs.

If you decide to flash and test some stuff the bootloader should be always unlocked. If anything will went wrong and your bootloader is locked you're mostly f***ed. Never relock your bootloader until you want to sell your device.
I mostly use flashfire to flash stock and custom roms, TWRP is ok too, but it's easier to keep root and TWRP with flashfire by flashing stock images. Do not flash bootloader and radio with flashfire, never ever !!! There are TWRP flashable zips for bootloader and radio here on XDA, you only should use these with TWRP, but the safe way for bootloader and radio is fastboot for sure. Fastboot is the safest way for flashing stock,
but not absolutely necessary, you have to decide this for yourself.
Edit: to your first question, I never flashed with USB otg on the n6p, but I think yes it should be fine.
I hope someone here can help answer this question. I also want to flash factory image version 8.1.0 on my nexus 6P. But somehow my phone is not recognized by any computers I tried to plug it in. When I plug in the usb cable to the phone, it doesn't pop up the usb notification to choose MTP for file transfer. Then I try with Developer tab in Settings to choose it manually (USB debugging is enable) but it still doesn't work. My laptop has been updated with android usb drivers and other stuffs. I have a second phone (Oneplus 1) and it's recognized by my laptop the moment I plug it in. Please suggest any solutions to fix this. Thanks everyone.

Check your cable, or try a different with different port.
In the Dev options you can reset the debugging options, i guess a reboot is necessary afterwards.

Thank you for the clarification. So, far I have not faced a situation to flash my custom recovery either thru' TWRP or thru Fastboot. Instead, I am using my Nandroid backups taken from TWRP and using it to restore my system after I try a custom rom OR upgrade my system with the latest Magisk version for a systemless root. So far there are no issues. But, I wanted to be aware of the methods to go back to stock (without any user installed apps/data) if need be. I read in some forums that we need to re-lock the unlocked bootloader if we want to go back to stock rom using fastboot. Otherwise, the system will not be installed alright and might cause a bootloop.
That's why I wanted to clarify.
Thanks again for your inputs.

You don't need to ever relock your bootloader. If you want to try stock and use TWRP try SuperXe 8.1. It's just flaahable stock with some extras you can opt out of your not intereseted.

I can't confirm the relock and unlock method to go back to stock. Senseless to me.
Hi, I downloaded the last update in OTA but after reboot I'm stuck on the boot animation.
I'm on the stock rom, never updated since I bought the phone in august.
I'm root and of course my bootloader is unlocked. I have TWRP that I managed to reinstall with ADB Sideload after this f***ing update get me back on stock recovery.
Now I keep trying install Roms (Official and customs) via ADB Sideload. Each time it look like the install is successful but then TWRP tell me "no os install, are you sure you want to reboot". Then I'm always stuck on the boot animation (at least it's the animation of the rom I tried to install).
Before I tried to update via OTA the 1st time I made a backup with TWRP but now all my files have been replaced by files with random letters ans numbers, so I can't even restore my backup and I'm affraid I lost everything I had on my phone.
What should I do now ?
Thanks for your help

as i said, after flashing a rom it tell me "no os installed".
by factory reset you mean format hd ? i'd like not to loose everything.
Then you have to format it and then you have to install the stock rom.
