No ROM! - G2 Q&A, Help & Troubleshooting

Hi,
I was running AOSP nougat on my int D802 and I saw a lineage OS for android pie so I d/l the rom, booted into twrp recovery and wiped the old os away and tried to install that rom but it gave me an error and it didn't install. Now I'm left with a phone that have nothing except TWRP!. Is there any way to download another working ROM on my computer and use any trick to let TWRP see the ROM I downloaded on my computer and install it from there directly?

Closed per OP request

[Q] phone stopped loading rom and won;t install new one

Hey
hope you can help with this:
the phone was unlocked, installed TWRP and CM11, worked perfectly, after a few weeks, the phone wont load CM any more,
I'm trying to flash the latest nightly or snapshot, but it keeps getting back to recovery? (even though it says all went well)
any ideas?
try update twrp
do you download the rom by ota or .zip and flash in twrp?

OnePlus 5 stuck on stock rom after trying brick cant flash anything now

So im trying to root my oneplus 5 and i started off by using Lineage OS but i wasnt too happy with it and i liked Oxygen OS much better so i decided to go back to it and while doing so like an idiot i wiped everything in twrp including the storage with all my ROM files and the phone was bricked and after a long struggle i used the unbrick tool which is called MSM tool which installed oxygen 4.5.8 using some some Qualcomm mode or something and it booted and worked fine but ever since i wasnt able to download the oxygen 5.1.1 update through the phones update section, it reaches 100% and says signature verification failed and goes back to 5%. So i tried downloading the latest Open Beta from the OP site and tried local upgrade which said installation failed so i try installing it locally through the Oxygen Recovery but again Installation failed so i try unlocking the bootloader again and installing it through twrp and it just keeps showing the boot animation forever( i know people say be patient but i waited for 20 mins+). So i decided to use the unbrick tool again and now im stuck on the OOS 4.5.8 unable to update the phone.
I tried to flash the latest oreo through twrp several times and just tried flashing it through so many ways where none worked , even adb sideloading it worked till 47% and said installation failed and everytime this happens i have nothing left to do but use the tool and unbrick it again and this takes so much time as i have to unbrick and then do the first setup and then go to fastboot and unlock the bootloader and do the setup again and transfer the files and then install twrp and flash.
Nothing has worked so far
And now even when i go back to the 4.5.8 stock after unbricking for some reason it just doesnt connect to any wifi , it just says Connecting and then saved and then disabled and repeat, only my mobile data works.
I tried to flash lineage again but got an error 7 with it or something and im back to the stock unbricked state without wifi and all i can do is unlock bootloader and install twrp.
If anybody has any suggestions and can help me please do so immediately. I require my phone urgently and need to fix this fast.
Thank You !
(btw im in India and do local service centres fix such issues?)
Make sure you use newest twrp. And also flash firmware for 5.1.1

Click to expand...
Click to collapse
i am using the latest codeworkx twrp 3.2.1 and when should i flash firmware? can you just give the process i should do? stuck at 4.5.8 without wifi with twrp and unlocked bootloader
Wipe everything except internal storage, after that click format data and type "yes" to accept. Then download oos 5.1.0 firmware from here https://sourceforge.net/projects/cheeseburgerdumplings/files/15.1/cheeseburger/firmware/ and lineageos 15 (or any rom you want now), gapps and move all 3 packages to your phone. Flash firmware first and then reboot to recovery. Then flash rom or gapps and reboot
You have to flash the latest TWRP from twrp.me, then download the latest OxygenOS build. Reboot into TWRP, wipe data, cache, system and flash the latest build, then just go to wipe > format data, type "yes" and reboot
Lol man your OP5 is not bricked, if you can boot on TWRP, you can install all that you want
I advise to Format Data/Storage, Wipe everything and install xXx 10.7 (OOS Custom with a great Aroma installer), choose decrypted, it's better if you want swtich rom in the future AOSP > OOS > AOSP
bro i have same probleme after install any rom custom or official , always stuck on boot logo , any solution ?
no solution??

Tab 4 LTE SM-T535 recognized as matissewifi

SOLVED: TWRP 3.0.3 uploaded by sub77 on androidfilehost doesn't properly recognize devices. I flashed the older 3.0.2-8 and it works fine and let me able to flash matisselte rom. Anyway, I flashed crdroid but It's stuck on boot animation.
Hello everybody,
I recently bought a secondhand Galaxy Tab 4 SM-T535. It has the android stock rom 5.2 and I wanted to flash a CM or any custom rom to speed it up a bit and remove all pre-installed apps. I did flash TWRP through Odin and it works fine, then I copied Gapps for 7.1 pico versiĆ³n and crDroid custom rom based on LineageOS 14.1 and nougat 7.1 for matisselte aka Tab 4 SM-T535. I followed instructions (that are pretty the same for every custom rom) so I wiped dalvik, cache, system and data, then I flashed (tried to) crDroid 14.1 zip and... TWRP says something like: unable to flash zip, it is for device matisselte but this is matissewifi. Wtf?! So, ok. I thought I'm blind and I got the wrong version, I downloaded the matissewifi version, tried to flash again and it did flash. Then I flashed Gapps and rebooted, now it goes directly in download mode and says Could not boot normally... What is happening? I also tried CM 14.1 for matissewifi, it flashes but can't boot and I'm unable to flash the matisselte version. Why?
it is for sure the LTE tablet, I read it in settings and info in the android stock rom and it has a sim slot, so it can't be the wifi one.
Thank you in advance for any reply. Let me know if you need more informations. Thanks.
P. S. I already searched in the forum and didn't find any similar case.
Hi,
has anybody found a solution...?
seen too late.....

So glad you posted this because I had failed in all my attempts and had tried a few TWRP versions but not that one, which worked perfectly with Lineage 14.1.

HELP No recovery, usb not recognized

Its a shame.
7 years unlocking bootloaders, installing CWM or TWRP or Philz recovery, flashing rom after rom, not even one device bricked, and today, i messed up, i hope its not bad.
So the short version of what i did is that i flashed twrp.img trough and older version of twrp and now it wont boot into twrp, it says that it failed to verify the recovery image or something like that, and my laptop wont recognize the cellphone, the cellphone boots into the latest Havoc rom but without Gapps and without root because i did not install it beforehand, when in bootloader mode it just says that it could not recognize the device.
The long version is that i had Resurrection Remix, obviously an unlock bootloader, magisk etc... everything was fine until today that i tried to install Havoc, the installation went well but i found out that ambient display was not working, someone told me that the previous version of Havoc did not had that problem so i tried to flash it but it bootlooped for like 1hr, so i read that the version of TWRP provided by the OP was the way to get it to work, i downloaded the .img file and flashed it trough TWRP and tried to install Havoc again but i was stuck in a bootloop, so i flashed the latest Havoc build so i could download the latest version of twrp, i did not flash Gapps or Magisk because i was going to re flash the rom and then flash Gapps and magisk, so i downloaded TWRP and flashed trough TWRP and thats when the sh$& hit the fan, now it wont boot into TRWP and my laptop wont recognize the device, neither on android nor in bootloader mode.
So, thank you guys in advance for your help, tomorrow im going to try on a computer at my work and see if its my computer and if not, well, ill have to se what you geniuses come up with. thank you so much again.

Error while installing gapps for 8.1 oreo based custom rom on Potter

so i was on oreo 8.1 soak test version and wanted to upgrade to a 64 bit custom rom based on oreo. unlocked the bootloader. flashed TWRP (3.2.3-1) . Then i flashed franken rom based on 8.1 and opengapps arm64 mini for 8.1.x. everything was right until i figured out that there was no fingerprint functionality. i followed this thread https://forum.xda-developers.com/g5-plus/help/fingerprint-enrollment-custom-rom-t3804908 and first flashed the persist fix zip and then the stock 7.0 rom. everything worked fine and i was on stock 7.0 and then i tried to again flash the franken rom but this time the rom was flashed successfully but during gapps installation i got ERROR code 20 and it said something like "incompatible rom found". it was detecting the the rom as 7.1.2. but neither the stock was 7.1.2 nor the franken one and i had also wiped dalvik, data, system and cache before flashing the franken. i tried again and again but failed. what may be the problem here?
sorry for the story like description
