[Galaxy S 5 Q&A, Help & Troubleshooting] facorbin:
I'm sure I'm doing this wrong.

So this week I bought the ad-free version of this site. I have some questions. Before I get into those, I would like to preface them with a short statement. Its not nice to be the last at the party and the 1st to complain. So, if no one responds, I wont feel slighted in anyway. I suppose I'm an old man to be posting and asking questions in this arena. I have spent around a year reading the post and questions on here and politely lurking in the background and not buzzed everybody wanting something done that I could do myself. A looooooooooong time ago, DOS,Win98,XP, Nokia phns, and Motorola Rzr, I used and advised ppl in forums like this. I say that to say that I do understand the culture in the groups and how ppl think and value of time.

Now, This is what I can do.

I can operate ODIN

I can operate KDZ flash tool.

can operate CDMA workshop.

I can build and refurbish screens with proper equip. (7000.00) in my shop.

I can even micro solder on boards.. Not quite as proficient as I would like at reballing chips but I can hold my own.

I can effectively operate scripts and use the basic rooting tools.

I don't have a lot of time to leisurely read and study all the guides for hours to find the one unique post to solve a problem. THE DIFFERENCE BETWEEN ME some kid crying because broke his toy before his mom finds out, I DO NOT MIND PAYING ANYONE FOR THEIR ASSISTANCE.

Now, with that being said. I don't expect anything for free. I did my "homework". I learned to reasonably operate the software. I know the difference between a img and a zip. Now, I have some advanced and some complicated questions.....

I often get a number of devices traded in or brought for repair that have been soft bricked and since its not practical to spend 6hr @50.00/hr to locate some obscure SW. and attempt to run a business, I come here.

1st a simple question. all this talk of 'locked bootloaders' and exploits, I don't understand why a phone like for example my s6 edge g925v running os 6.0.2 could not be completely wiped and the original firmware (ex 5.0.1), kernel, radio mdm, and pit be rewritten to the device?

2nd simple question, tracfone variants of vzw equip are purported to have open bootloaders. yet even if one has the firmware for the matching vzw model and in some cases the tfn firmware and having never been updated fail on every attempt to write the correct firmware. I have attempted every effort using dealer software, qcmm sw, cdma evolution level software cannot read the correct raw memory locations of firmware of the particular device.

Can someone explain the whole theory and the correct method to do this?

1 tfn sm-s902l SV variant running 4.4.2 brought to me with knox tripped. due to failed rooting attempt via 1-click/kingo root. boot loop. best I could do was to use the nk2 kernel to get the device to turn on. on every reboot device attempts to update 2 apps and content service stops and S-health stops.

customer just wants the os to be stable with out errors. could care less about knox.

at this point rooting is a bonus. restoration of stock function is all she is requesting and as such I am asking. Donations are not a problem. I have the sam mobile orginial firmware but it fails at aboot with a binary>2 >3 error on phn.

2.tfn Galaxy grand prime sm-s920l bootloop. failed rooting attempt by local kid. I repaired phn by replacing board out of broken screen one I had in junk pile. would like to restore os to resale as used phn or loaner.

Ok. Those are my questions. I have team viewer and a stable 8mbs connection if anyone wants to do. donations are cool with me if someone can help point me in right direction.

I can provide addition info in pm or here as necessary.

If there is anyone still reading this, thank you for your time and I would appreciate any help.

Again, its not that I don't want to learn but I have a business to run. I want to learn but I cant spend forever on these things. If you can help me, efficiently solve this problems and show me where I am stuck I will be sincerely greatful and will compensate you as necessary.

If you want to lord your knowledge over me in some ego way just save it. I don't have time for ego games.

Thanks for you time,

Francis

ps. if I seem to have an attitude, its because I don't find arrogance a positive quality. Its a sorry person that wont help themselves and a worse person that can help and doesn't out of sheer petulance.
