Read OP HERE ! There is clearly written how to flash modem and bootloader correctly... If after carefully reading how to do it, you continue to have problems, try to download the files again

Hi, so it looks like I was completely mistaken and I'm sorry for all the misunderstandings. It looks like I didn't properly check MY baseband version. The files you provided on this forum has files that weren't actually compatible with my model. I checked the first 5-6 characters of my baseband and it was N900W8. And the files that were on the forum were N9005 which was different and that was why it failed to keep flashing. I needed to flash the right version of the baseband and bootloader.
Thanks for all the help from before

I searched the forums but could not find what I was looking for. Is there a thread that folks comment on cheap rootable phones? For my purposes it will only be used for dev work, i.e. android app development, my main device is iphone so I don't need it for day to day use.

As far as I know, there is no thread dedicated to cheap rooted phones. There is a [Discussion] What's your next smartphone / What should I buy thread.

My opinion is, depending on what you're looking to develop, you will want a device that has an official A10 release. There are enough changes that using an older OS could be problematic. Again, you're not specific as to what development you want to do, but in my opinion, a used pixel 2 is virtually unbrickable and has solid support on A10 (though that is it's last release). It's maybe not a good choice if you want to develop specifically for Xiaomi or Samsung though.

I would want to caution that a cheaper pixel 2 (or any Google phone) is probably a Verizon model with an unlockable bootloader.

I would also think that you could find an Essential PH-1 which also has official A10 support. The Verizon problem exists with these phones also.

hmm, too expensive for my needs, anything in the sub $50.00 range that you can comment on?

As for dev purposes:
Android App Development via Visual Studio For Mac and Xamarin

Really i have no words! Anyway, thanks for saying that...

Need help in converting stock ROM into custom twrp flashable zip. All information on internet about this didn't helped me.so I need help of a developer.?

New to this

I have been sucessfull in installing custom roms to my phone (Treble GSI ones), but they all seem to miss features that other phones have main thing i has noticed is gestures and i know some have like android app lock thingi but yeah.. My question is what gives phone like gestures? is it kernel? or vendor.img? or roms themselves? anything would be helpfull.

Generally speaking, it will be the ROM, and hence there are 3rd party apps. However, gestures such as "double-tap to wake", require kernel specific features. It would be best if you specifically list which gesture you are asking about.

Droidriven said:

Features that only have a purely "software" function are built-in/enabled in the ROM(system.img)

Features that utilize hardware in the device in some manner to provide the feature are built-in/enabled in the kernel(the kernel is actually usually baked in the system.img but is separate from the "ROM").

I just wanted to get basic android, but it seems like ASOP GSIs are way too basic with no features being added ig. Imma search for smthing else then. Thank you for your replys.

Maybe you might try some from this repository https://mirrors.lolinet.com/firmware/gsi/ of those that I tried HOS and OOS include some nice gestures and they just have some minimal tweaks over AOSP without mentioning Miui or Samsung that also have but they´re very different from the original source.

Bro not working backup method too. If u help I can tell you which phone is I'm using and all information.

Any of them potentially can boot on your device but it needs to meet some minimal requirements that you have to take in account.

here you have a basic reading to better comprehension of https://www.xda-developers.com/flash-generic-system-image-project-treble-device/ and also you will find some links to forum for devices that you have to compare with the yours and investigate what you´d need to fix in order to achieve your goal.

Here other huge repository with some roms that I know that have what you´re looking for like Evolution, Havoc, AospExtended and a great etc of "OSs" https://github.com/phhusson/treble_experimentations/wiki/Generic-System-Image-(GSI)-list

And here a specific guide with the steps to can succesfully boot a device that could be applied in almost any device, be warned that this is an image for an AB device but from those mods that I know; "permissiver v5" would match with your device https://gist.github.com/TheGabrielHoward/f66ca7970966b60f40474bbbc714a34d

Hi everyone, first I'd like to thank all those on here that know what they're doing and willing to help out the newbies

Ok so here's my situation

I bought a used V30 LS998 from Amazon and I'm thinking of rooting it

Being new to rooting there's a lot of information to sort through and absorb

This phone will be my daily use phone so stability is important

The problem I'm having is the multitude of options, i haven't done anything yet (including the OTA update my V30 wants to do, it's currently on march of 2018 software) and I've read a handful of how to guides, i guess I'm looking for an experienced guide to point out pros and cons

I know being a sprint customer i want to keep my phone a LS988 for the LTE bands (i would lose 1 our 2 switching to US988 software)

So my question is what would the people with experience recommend? I was looking at havoc Rom because of the options for performance gains but found little information on havoc on the V30 specificly and not sure I'm able to control the gain or loss of bands (things change quickly and some of the threads go back awhile) i was also looking at JohnFawkes guide to installing 30a firmware which seems fool proof and i still have the options of downloading whatever root apps i want to accomplish my own goals, so am i missing anything?

I'm humbly asking to be schooled here

I'm not concerned with Google pay and i can take or lose Netflix but I'd like the strongest signal possible and want my text, data and calls to work consistently
I do play clash of clans consistently and don't want anything to make that not work

My other issue being i don't even own a computer [emoji28] my kids have them for school but I'd like to use them as minimally as possible, i know at the very least it's necessary initially but what about later changes?

In quite urgent need of help. Got 2 Galaxy S8+ phones here. I am in Australia. Australian Galaxy S8+ Model I have is the G955F, the other model which I think is USA is a G955U1 or UI I think. It was sold on eBay as an Australian model and I don't think it is after doing some research.

I have noticed that when putting the sim card in the Australian model it shows up on the top bar as '4G' for the network and on speedtest I get a down link rate of 94 mbps.

With the American model I use the same sim card which shows up as LTE instead of 4G and when doing a speedtest I get a rate of 20 mbps.

Bit frustrated about this as it seems it is not able to get the full use out of the frequences here in Australia which is affecting signal, calls and network.

As you lot seem very clued up on this can I ask if you know a fix? Software wise or hardware? Without having to replace the actual mobo and phone.

Thanks

First i wanna thank you for helping me. Secondly i got my first big heart attack.(i have had mini ones ) I flashed the boot image recommended in one of the guides and all of my buttons stopped working... Luckly i managed to flash old boot img back.. If im not mistaken boot contains kernel? and secondly can i like merge 2 boot images so mine would still work but i get new stuff from the second boot image?

Wanted to clearify

First I have to say is that you must have a plan B to can return to mainland if something goes wrong so bricks and mistaken are parts of this business, of course you can experience some of them just in little doses if you don´t do nothing weird like use a kernel for other device nor try to merge two boots in one.
Taking a GSI that was adapted for other device you are adding a double difficult so this images no longer are GSIs cause they were modifiied.
You have to take only universal (sorry for redundance) GSIs, no matter what device they come from but that remained untouched or were adapted for your device (and think this is not the case here).
Don´t use a boot from any other rom, ever use your own vendor and boot.

Boot up can´t take more than 15´. Probably you´d need to format data before and after.

Unfortunately there´s not a recipe that works in all the cases, this will depend on how much compatible are the boot and vendor from your device (you can switch here for others if available combining them) with the GSI in discussion, and also the steps may produce different results.
