whitedavid: [B]into recovery. But every time, after I have finished the procedure, when I try to reboot recovery I end up in stock recovery mode. It is as if the flashing or dd'ing, etc is not "sticking". Anyone have any suggestions as to why this is and how to get this done? Thanks![/B]
~ Haven't a clue, D. White 'privilege' revocation?
I hear it's all the 'rage', these days? Not sure what W. P. is exactly,
hadn't seen it either,... supposedly it's dangerously bad

That's best I can do for wtty, anymore. Sorry if in poor taste, pc void,
with touch of smartArse sprinkles. I used to possess the wit.

Back to cases, let me relay jan '21 Ugoos Dev changes.
I'd say the two are true "competing brands".
For 13 months, from fw ver? 1.01 thru jan 3.8.x ...maybe 7 upgrades- I learned to copy stk recovery, I thought I would remove it, yet now thinking I don't recall extracting process. So now I'm pretty any updates just wrote over TWRP, or I May have just swaped back in stkRec tho. Then reflashed TWR No worries.
Late jan rolls 3.9.1, on the heels of two prior upgrands. Being behind, i read the changelog, but not release added notes. I lose TWP, box is so rock solid, and runs great... After a couple of fails, I just put off the TWP flash, running as is, using Titanium Bk-up for System, but mostly apps. I have Not been successful restoring full
Apps, settings, and android with Titan. Not sure why either. Probably several more hours of reading. It can't see the os, so No Bkup either.
AN Excellent maintenance tool tho.
To shorten a long story in runaway.. Here comes v. 4.0 with major revamps,
similar to 3.9.1. Get TWP to install, no matter what. Between the release notation (not commonly incl), and freaktab.co... I find 3.9 was the start of Encrypted SW. Also last sw that will rollback. Even worse just to 3.7 skipping 3.8 (!? Incremental?). Now It's
Imperitive to load TWRP, IT HAS saved my total collapse more than once. No such luck looking thru OS Files for SU removal to aid per majisk I see TWO Recovery files. I look in multiple OS Files after profile request sez 0 data. I guess that's the encryption? They're All empty, absolutely unchangeable, content, name, loction.. Zero, zilch.
OKAY, Moving on to updarer script(s)... I guess devs are familiar, but shocked me-
Considerably more complex than before. They Appear to be done in 3 stages, each circle back touching on the recovery file- reason for multiple recovery files within the system data? Methinks yes.
I won't be doing a script change. UGOOS support sez they've run TWP, as yet won't condemn the app, nor give up their scripts, or process instruct. But say they normally work bigger issues, having emergency quaalifiers. She WAS kind enough to refer me here to MagMan's work, because the "project" is slacking for STB help ChadM has made Every TWRP I've run for 3.5yrs now (1 reason for extra backstory), hoping
he'll look herein. The guy is freakishly busy tho, and gives these forums, and their volunteer victims Soo much already. I sure am thankful... He's crazy. ;- )
... Ugoos's "Becky" also referred me to Freektab.Co - where I have been consistently for about 4yrs. Somehow, I will getter done. Have to! I'd love to follow ugoos rolling improvements, but with anti-rollback AND encryption (plus, I think I picked up a bug) I've got to dump a couple of updates, and stand. Or move Fwd with this outstanding device, and the talented vision that's driven it. ...BUT, w/o my dependable TWP, I'm seriously Risking- a catastrophic box-killer incident...
Probably over due as is, with no pc and even less USB-flash skills.
My advise is looking carefully at your system files, search, bin, xbin, +?? For 2
or more recovery file with slightly differing names. Compare recent install scripts
and said files, as well as, default permission/ perameters to a few historical ones when you recall having an easier time getting twrp 'nailed' in.
look at your recovery log also.
I'm Pretty sure your "WHY" will become, fairly obvious then.
LUCK 2U & All ! ~jd
