6.6 rollback options?? - BLU R1 HD Questions & Answers

I have seen talk of ppl trying things out as to how to roll back from 6.6 to 6.5 in order to unlock the bootloader, install yerp, etc. Has anybody on this forum heard of anything I could try? I obviously didn't do my research on the phone before updating it but I do have average experience with rooting, using Android SDK and spft so any suggestions are welcome!

it has been mentioned that the only downgradable (or workable) v6.6 is when it is installed using the SAFE method.
http://forum.xda-developers.com/r1-hd/how-to/safe-v6-6-prime-update-via-twrp-t3459257
but if not, as ColtonDRG himself said : "The V6.6 update brought a new preloader that breaks our ability to use SPFT. I am currently working on ways to reverse the damage, but as of right now, there is no way to convert (or downgrade) from software V6.6."

I have not yet rooted it so everything is still stock so upgrading via the safe method doesn't really apply for me. Thanks anyways, guess I'll be waiting for a new root method to come about. Hopefully ppl haven't already forgotten about this phone lol.

[Q] New to tablets and ROM

Hello ya'll, I'm new to the forum, I joined because of the wealth of information here.
So I'm not new to Android, had one ever since I was 16. I rooted both my droid phones(droid X with that awesome slider keyboard, and RAZR MAXX) to remove those pesky bloatware apps, but didn't ROM them, as it just wasn't something I wasn't aware of when I did it. So rooting was as far as I got.
But rooting and ROM-ing a tablet seems like it could be a daunting job, I'm new to the tablet world But I already have most of the tools, from previous roots, minus a few that are platform specific that I'm currently downloading to support the new CROMBi-X
I figure I'll go about getting everything I need, so when I get my tablet back from the shop, I'll be able to dive right into the CROMBi ROM.
//
I don't want to brick my tablet so hence the questions I am unclear on.
//
Question 1: Asus doesn't have the standalone unlock tool on their website. How do I go about getting that tool to unlock the tablet? Was it done OTA or downloaded and installed onto the tablet?
I have searched a few places, and browsed the developer forums, but haven't come up with a surefire way yet. I've seen everything from asking ASUS to unlock the tablet, to flashing CWM recovery, and than flashing a rooted version of the stock ROM, 've read several of the forums, but I need a little bit of "English" on the topic, as this is something new to me. I did come across a root.zip link but I'm not entirely sure that is what I am looking for, or if it is version/BLoader specific. If it is, then that pretty much covers that question.
Question 2: Are all the drivers on the ROM? Or do I need to use something like [ADB/FB/APX Driver] Universal Naked Driver 0.7?
Question 3: Mods. Are they downloaded OTA from the play store, or is there a list of compatible mods for the ROM? I realize that most of them are probably cosmetic right? I'm probably asking in the wrong forum, but since this is LINUX based, once rooted, if I put Ubuntu on the tablet, and then run a ROM on top of it? or Do I have to choose between one or the other?
I'm only asking because I run a few programs that aren't able to run on the android platform that I use for recreational purposes.
Anyway, that about covers a few of the base questions I have for now. Time to get ready for work. Thanks for any help in advance!
For 1:
It's on ASUS website
www.service.asus.com/#!downloads/c1wax
Version V1.0
Unlock Device App: Unlock boot loader of TF701T.(Only works with 4.2 JB and later OS)
For 2:
It's been a while since I rooted however I think you only need fastboot to be able to put the custom recovery on the tablet. If you have ADB/FB drivers already installed your pc should see your tablet without an issue. I don't know what APX is.
For 3:
Not sure what you mean by Mods. And last I checked I don't think that you can and Linux to this tablet yet however even if you could you only get one or the other.
Oh and make sure you read through all of the instructions for rooting and roming

sleepy2 gave you the link. You find the Unlock Tool under "Utilites" on the TF701 downloads page

First you need to determine what firmware you are running now and decide which JB version you want to run.
Check under Settings > About Tablet > Software version. On stock your firmware version and bootloader version are identical.
If you are on JB 4.3 you have either 10.26.1.7 or 10.26.1.18 (if you have the former, update to .18)
If you are on JB 4.4.2 you have 11.4.1.17
On JB 4.3
a) You can root the tablet without unlocking the bootloader with Towelroot v1.
b) You can unlock, flash CWM and then flash sbdag's stock rooted rom, one of several custom roms or just the root.zip
On JB 4.4.2
Right now there is no way to root without unlocking the bootloader and flashing a custom recovery first.
Once unlocked and with CWM installed, you can flash sbdag's rooted stock rom or flash the root.zip.
CROMi-X 7.0 for 4.4.2 is in the works. I do not know if the other custom roms (CM, CROMi-X 6, CROMbi-KK) are compatible with the 11.4.1.17 bootloader yet, but that's just a matter of time.
To install CWM follow the insructions here:
http://forum.xda-developers.com/showthread.php?t=2604462
Question 2: Are all the drivers on the ROM? Or do I need to use something like [ADB/FB/APX Driver] Universal Naked Driver 0.7?

Try it. I did not have to install new adb/fastboot drivers and the device drivers installed on my PC automativcally. YMMV
Open Device Manager, then connect the tablet. Let the drivers install and see if it shows up in Device Manager.
Then boot the tablet into fastboot, connect it to PC and see if it shows up as a fastboot device.
Enable USB debugging in Developer Options, then connect the tablet booted into Android and see if it shows up as ADB interface in Device Manager.
If you need drivers you can use the ones you mentioned.
Question 3: Mods. Are they downloaded OTA from the play store, or is there a list of compatible mods for the ROM? I realize that most of them are probably cosmetic right?

You'll find mods in the rom thread or at least the links for those that work with that rom.. No OTA updates
I'm probably asking in the wrong forum, but since this is LINUX based, once rooted, if I put Ubuntu on the tablet, and then run a ROM on top of it? or Do I have to choose between one or the other?

There's a thread in the TF700 dev section on dual booting Android and Ubuntu. Not aware that anybody has tried it on the TF701.
Thanks for the link Sleepy! I had searched the website a couple times before, but I must have missed that part of it. Every other time I went somewhere to find it, it came back page unavailable. I'm really disliking this Kuwaiti right now! Well I won't know until I get the tablet back what JB is on it, but I imagine it would be sent back to a factory setting because of the issues I was having, or just get a whole new tablet all together depending on what was causing it not to charge.
I appreciate the clarification on everything guys, without the tablet in my hands I'm pretty much downloading everything I can that might help me out. I already have CWM, and several versions of it to be on the safe side.
I have been doing nothing but non-stop research, but it's daunting to try and go through 115 pages of information and tools, and version changes and what's compatible and how to use them. Watching videos has simplified it a little bit.
The reason I asked about Ubuntu, was I saw it dual booted to an older CROMi 2.X on the 700T
I used to run XP pro/Ubuntu on my laptop. Which was really nice when I needed a lightweight OS to free up processing power. Well before I had to format due to a near catastrophic drive failure and unrepairable data corruption. Anyway, that is a project for another time, one thing at a time!
I'll be around, busy with work 6 days a week!
Thanks again!

List of repairs done
So what I thought was a simple battery not charging issue turned out to be a host of things. I had to have the LCD, Touchpadboard, Docking cable and LCD cable replaced, luckily I was under warranty. I imagine that would have been expensive!

A little guidance please

I have had my G2 for about a year. I had rooted it and never took an update after 11A. I was happy with the way my phone worked and read some of the stories where people were not happy with KitKat.
Unfortunately, the touch went out on my screen and I had to get a replacement. I successfully flashed my old one back to stock and removed root w/out a problem.
Now my problem is this:
The new phone came with 25B. I understand there is no way to root this version. The phone is already wanting me to update to 26A. What I would like to do is rollback someway, root, then take updates. I can already see my phone signal is not as strong as it used to be.
My questions are:
1. Can I rollback to an earlier version and root via one of the IORoot options? (TOT it like I did my old phone)
2. What version would I need to rollback to to accomplish this.
3. Could someone point to the correct thread to do this?
4. Finally, I see it seems to be ok to take factory updates if you are rooted only. I am not interested in custom roms. I use Titanium Backup to freeze bloatware and would like like to be able to use it again. I have quite a bit I need to restore.
I have done some searching but it seems the G2 section has changed a lot since I was last here. I do appreciate any help and/or pitfalls you can warn me about. I do have the LG Flash Tool 1.8 installed and am familiar with how to install the needed TOT file.
Thanks....

You can kdz or tot back and root from there. Root sticks through 25b but not 26a update.
Thank you. I will go ahead and update to the 25b then.

Canadian P20 Pro version CLT-L04, Questions about Magisk and bootloader unlock

Hi! I picked up my Canadian P20 Pro last week and couldn't be happier. It's been many years since I've owned a rootable device though and a lot has changed! I've done my best to read through all the guides for rooting the P20 Pro and it's only lead to further confusion as there seem to be many recent advancements. There seem to be a lot of different versions of this phone too. So I have some questions I'm hoping someone can answer easily! Let's assume my bootloader is already unlocked....
1) there's a really great guide on rooting the P20 Pro using All In One tool. But that requires flashing TWRP to achieve root using Magisk. I do not require TWRP as I only want root and do not wish to flash any roms.
a) is there a way to root with Magisk and NOT flash TWRP? I can't seem to find a straight answer on this...
b) failing that, can TWRP safely be removed and keep root afterward?
2) after unlocking the bootloader I was welcomed by a terrifyingly orange warning about my now 'unsafe' phone. I've read mixed things on hiding this. Is there currently a way to hide it?
3) how does the process work for OTA updates on an unlocked bootloader assuming there is no TWRP? I've read differing opinions on the necessity of flashing a no_check.img to the ramdisk and have no understanding of the new security checks on these phones. Can I run risk of bricking my phone through an automated update?
Ultimately I'm scared of forgetting TWRP is on my phone and accepting an update that'll brick it. Any information is welcome as are similar questions!
I am also curious if there is a good root process for this phone. Find anything yet?

I have a Canadian CLT-L04 that i rebranded and rooted to CLT-L29 with the guide on here.
https://forum.xda-developers.com/hu...de-how-to-root-debrand-remove-retail-t3788326
if you want better firmware compared to version 109 thats still on clt-l04 you can follow this guide, it worked well for me. (don't wait canadian OTA it'll take too long)
1) quite sure that TWRP is the easiest and safest way to root. Currently unaware of a better way to root the phone.
b) if you remove TWRP by flashing a stock recovery_ramdisk, root is kept. If you do an OTA though you might lose root.
2) thats here to stay i believe. Cannot find a way to hide it currently.
3)In this guide under the "install an OTA Stock Update: PC Method" you will find all the information you need.
cheers
I finally found the info I needed in this thread:
https://forum.xda-developers.com/hu...ide-getting-started-unlock-twrp-root-t3806180
Overall it was a very simple process and took less than an hour including reading. Once you've got your bootloader unlock code the all in one tool handles it from there. Unlock the bootloader, flash TWRP, reboot into TWRP, flash Magisk and you're done. You can flash the no_check file over TWRP if you want to be ready for updates but I decided to leave TWRP on for now. Loving having root on this phone so far!
On a different note, has anyone discovered any ROMs for this phone yet that can handle the notch? I almost tried Lineage until I found out there is no notch support. I've grown strangely fond of the thing for some reason lol

If you do a full backup of the L04 in TWRP before rebranding you should be able to go back to it easily at any time, just remember to save it somewhere safe other than the phone itself. If you've already flashed and are looking to go back you may find someone willing to share a stock backup if you ask around. But always best to do your own backup first, then you can go back whenever you like!

Anyone unlocked bootloader and rooted recently for the L04 model with 120(C792) Sept-2018 update?
Im scared to update before unlocking and rooting as the update might do something to fastboot etc. (this has happened to LG)
If not, then Ill update but if so, Ill just not update and unlock it as it is.

It's really easy to update once you've unlocked, I would suggest unlocking first if you have concerns. I have an L04 as well and just updated to 120 with no problems.

No problem, glad it worked for you. I've soft bricked and recovered my phone a few times now experimenting so if you run into any problems I'm happy to help! Lots to learn with the P20.
I have a CLT-L04 8.1.0.136 C69 with October security patch from Mexico I want to rebrand it to CLT- L29 to get wifi calling and get rid of all the bloatware. Could I use this tutorial from dladz's tutorial:

I have only rooted one phone before in my life so I am no expert. I do no want to mess up my phone becuse it is the only one that I have. Also If I unlock the boot loader and rebrand can i get OTAs and the upcoming Pie release? Thanks for the help!
LineageOS 15.1 on L04

Did you install it with a locked bootloader ? I really dont feel like paying for an unlock code. Would like to try Lineage though.

I do have an unlocked bootloader. Truth is i'm addicted to Rom's lol. That in mind I have tried every Rom, kernel, flash-able zip within this Forum and I can't brick this thing. L04 Canadian. Lineage is the best Rom for our device.
Roms that work:
- Lineage - Hauwei camera can be installed and works, dark mode works well.
------- Doesn't work: USB-C audio, NFC, RAW Option in the camera, Second ear piece as speaker, main speaker works well.
- First Ever Android 9 - Being the first build it works well. (Note: When I installed this rom I never installed the RemoveEncryption-P20Pro.zip) Seemed to work just fine without it. I did run it just because I wanted to see if it would brick my phone. It didn't.
-------Doesn't work: Dark mode, NFC, RAW Option in camera, Second ear piece as speaker, main speaker works well, seems to kill TWRP. eRecovery needed to get TWRP to function.
- AOSP 9 - Berkeley-Flex - Do Not Use...not ready.

Rooting Pie

Hi
I will have my N960F/DS in a couple of weeks. I prefer not to root it for at least a couple of months in case of any warranty issues. However, by then it should have upgraded to Pie. Does anyone know whether the current root methods will work under Pie? Do they work under the current beta?
If your phone has an unlocked bootloader, pie won't change that. You're probably thinking about the exploit days that new updates patched.
So yes, it will be rooted as soon as the devs build twrp.
Great! Thanks!
Similar problem
I have a brand new N960FD and im have the "only official released binaries are allowed to be flashed" because i installed twrp and tried to do so with no-verity-encrypt and RMM state bypass. but now im stuck and i don't know what to do to root my new phone... (with magisk, which didn't work as well....)
I just want pie with root and no trouble.
Anyone can help me ?

read carefully Dr.ketans post in the general discussion. its pinned.
nothing anyone can do for you that you can't do by yourself by reading. i would also suggest you to read throught Docs whole pinned thread(user comments) and then do the same thing with the twrp thread in the dev section.
all issues and questions have come up sooner or later. you just need to want to take time and read.
down the line, you'll have also more questions and these answers would probably answer themselves after those 2 reads.( might be a lengthy read but sure beats having a phone that is not operating like you want it to)
Samsung account problem
I have the same model, n960fd, rooted with magisk tests checked, everything is fine, but when i want to connect to a samsung account, it loops and ask me again for the password, non stop.
Is there any known solution ?

newbie warning: don't re-lock bootloader, and beware flashing any custom ROM. &OTA...
only modify a phone you are willing to throw away.......
##
pre-note: TWRP 3.3.1-0 -> fastboot boot twrp.img (this is temporary)
before doing anything, backup some little partitions: EFS, fsg, Vendor. Maybe others. You will need these to get back to a working stock.
##
$$
DO AT YOUR OWN RISK - I TAKE NO RESPONSIBILITY.
note added 2-27-2020: it may be that some problems with returning to stock are due to not (in TWRP) advanced wiping data, system, dalvik ART cache before flashing. You can do temp "fastboot boot twrp-3.3.1-0-payton.img" w/o quotes, and do it there. -changed/edited. don't use TWRP to flash a stock zip!
$$
NO FIX IS KNOWN FOR ANY OF THESE PROBLEMS. PHONE IS DESTROYED.
newbie warning: don't re-lock bootloader, and beware flashing ANY custom ROM.
On the X4, the bootloader changes drastically between 8 and 9 as it introduces a dual file system which is used by OTA updates to alternate the live system, and as a backup if failure. It is not a true Treble system, only partial. You must not depend on being able to flash back and forth between O and P. If you update to P, stay there. I expect this to be exacerbated by those phones which update to 10, if that in fact happens(probably One/fi only). There is also much confusion as to which file system/setup any custom ROM uses, and thus, how you would get back to stock, if that is even possible. Be very careful and assure yourself that you are fully willing to lose permanently your new phone before you do anything. Please read posts in these forums.
I've seen many posts of folks, mostly noobs, who have flashed ANY custom ROM Lineage and are unable to get back to a working stock. Sounds super simple but apparently it's not. Best to assume that if you try things, especially Lineage, that you will never be able to get back to a working stock. Read a bunch of posts here and you will realize that.
I've also seen a bunch of folks on this phone, and other phones who have run a bat file to flash their phone which contains the line
"fastboot oem lock" or similar.
Don't do it!!! - This will lock your phone and you will never be able to do anything with it again. It is totally unnecessary to lock your phone. Folks who should know better are leaving bat files lying around with this command. If you use one of those bat files to flash your phone, just check and remove that command line. Else you will have destroyed your phone. That's one of those things that "sounds good" until you do it.
EDIT: You can run stock on a bootloader unlocked phone - I do it all the time - plays PoGo just fine. I don't know about banking apps - I don't use them as I assume any 10-year-old can and will hack my phone.
EDIT: 6Feb2020: folks are reporting taking a security OTA onto a modified phone and rendering their phone(s) unusable. Only take OTA to a pure unmodified (no Majisk ever on it)(etc)(no mods ever on it)(stock recovery)(etc) stock ROM. Heed this warning. All of these "temporary" mods leave traces that screw up the update process.
EDIT: this was successfully fixed. see: https://forum.xda-developers.com/moto-x4/help/ota-update-endless-fail-loop-ppws29-69-t4045771 my guess is only works if you haven't changed bootloader or file system - NO custom ROM.
NO FIX IS KNOWN FOR ANY OF THESE PROBLEMS. PHONE IS DESTROYED.
Please do a lot of reading here before you try to modify your phone, unless you are totally willing to render it useless. A word to the wise.
Ahah ))) I bought today X4 with relocked BL and I it seems it was relocked after flashing LOS or similar )) )
Now I trying to recover it ))
Сan we boot phone to QC9008 (EDL) mode without testpoiint?

afaik, you can't. Return the phone and get your money back. There will probably be a bunch of these worthless phones put up for sale. If you can't return it you could try the suggestions of sd_shadow in other threads here, but I don't believe they were successful on the X4.

Good to not be trusting!!!! With this (or any) phone, I recommend you get only from a place (like ebay) where you can easily return it and get your money back. ebay can force a reluctant seller to refund your money. Assure that the seller has a 99% + rating and says they will accept returns and pay for return shipment, usually for 30 days. I don't think you can easily tell if it has been unlocked and re-locked - only that it works perfectly, or doesn't. You can check the ID of the ROM in your phone against the latest for your area by checking lolinet.
When you get it, check all functions and assure IMEI is present. check wifi, BT, etc etc. Make calls. Check that the phone works with the towers in your area and with a local SIM. etc etc. read here and find the things that folks having problems where it won't do things and assure your phone will do it. Install Pokemon Go on it and play it briefly to assure your phone hasn't been modified. I have no idea if any of these phone will work with any banking or payment apps, and each app will have it's own specific checks that it performs against the phone. Test what you will use. Fully. ASSUME NOTHING!!!
As far as rooting it and/or unlocking it, I would strongly advise against it. For this particular phone X4 I would determine that it works perfectly and then NOT modify it. Unless, of course, you are willing to throw your phone away and buy a new one without a second thought(most of us don't have that kind of money!). Mine happened to have been unlocked when I got it from ebay but it was on a stock 8.1 and it was able to, and did OTA update to the latest Pie stock ROM. Thus I was easily able to assure if was okay. It being unlocked seems to have affected nothing. I have never tried to root it or do anything to it (recovery or otherwise) as I read far too many posts of folks here who had rendered their phones incapable of returning to a working stock, and only on a limited custom. Not what I wanted. I have not heard of anyone successfully getting one of these phones back to a FULLY WORKING stock state.
The days of getting a phone and easily modifying it and then returning it to stock may be gone. Get a phone you will enjoy, and use it! Unmodified!!! Welcome to pre-Treble part1a . Expect a few years of growing pains.
I like my phone and enjoy not having to worry about whether a custom ROM will work and constantly be chasing updates and fixes. I use a case - I believe it is this one
https://www.ebay.com/itm/For-Motoro...hash=item33d89fee5a:m:mU5XV7jSj1TfD_kr-L4VT9g
which, so far, has protected it from several minor falls. I would never use any phone w/o a case!!!
But i think if the phone gets unlocked the bootloader and flash twrp making a backup of the stock recovery before just booting the twrp custom recovery then flash magisk on twrp on top of Stock PIE , After Of Course Make A Full Backup Of all partitions reboot and then on Stock PIE have ROOT. and never flash custom roms and never lock the bootloader and stock can be reflashed without problems with a script on linux with fastboot on bootloader-fastboot mode this plan can work , NO ? i had a E4 sprint and never had problems doing that
I need root for A Lot Of Things like Xposed Drivedroid Youtube vanced Adway ETC.
Can Anyone who is reading this have done this just root pie on this phone with unlocked bootloader ? and able to restore stock flashing it back with the retail firmware just to remove root and clean the stock and recovery ? or try to put android one ? the phone which im going to buy its the XT1900-6 retail brazil i already have the retail stock official pie rom ready to flash and with the script on linux with no fastboot oem lock anywhere .

I posted a new thread on these OTA issues with the X4 at https://forum.xda-developers.com/moto-x4/help/ota-update-endless-fail-loop-ppws29-69-t4045771. I was never presented with an "option" to install the latest OTA, it just automatically attempted to install (apparently a FORCED update) and is continuing to do so and failing ad infinitum. That phone works, just getting constant failure notifications. Question is, how to stop the attempted updates?
The second identical phone (updated per Magisk OTA tutorial instructions) is borked, with no phone connectivity. Can these be recovered by wiping/flashing stock rom PPWS29.60-39-6-2 and get them operating again as stock? I can forego the OTAs if there's a way to stop them from screwing up the device.
I never had other than stock recovery on either of these phones, I always boot TWRP via fastboot to do mods.
EDIT: XDA system is stalling and caused double post. Sorry. Mod please delete.

@redwoodie , please don't post to this thread. I read all your threads/posts but have no information.
NO FIX IS KNOWN FOR ANY OF THESE PROBLEMS. PHONE IS DESTROYED.
As to whether "x" strategy will work, you are certainly free to explore that on your own, in your own thread.
No one here knows. I am certainly not going to experiment on my own phone and run the likelihood of having to buy a new one. Folks like yourself keep showing up and doing just that because they are SURE it will work. But it hasn't.
Read all the posts.
There are very few folks left here on this forum. Once they have destroyed their phone, and tried a bunch of things, they move on.
THERE IS NO SOLUTION.
This thread is only to warn newbies.
I personally know nothing about the phone other than what has been posted by others.
Read it.
If you discover a true solution that allows a phone to work perfectly ON STOCK, please post it and you will make lots of folks happy, assuming it is repeatable.
However, no known solution.
But, again, you are free to explore solutions - just not in this thread, please. Thanks.
added paragraph at top:
$$
DO AT YOUR OWN RISK - I TAKE NO RESPONSIBILITY.
note added 2-27-2020: it may be that some problems with returning to stock are due to not (in TWRP) advanced wiping data, system, dalvik-ART-cache before flashing. You can do temp "fastboot boot twrp-3.3.1-0-payton.img" w/o quotes, and do it there. -changed/edited. don't use TWRP to flash a stock zip!
This guy is full of crap

I've literally put so many different custom ROMs on this phone. I've bricked it, unbricked, hard bricked it and soft bricked it. Stop misinforming people bro. The Moto G6 I would say to be careful with but still I wouldn't make a post like this guy. The Moto x4 just requires a little prep to make it a full treble, GSI accepting, custom Rom beast. Plus there are a few official ROMs out there even Android 10 for the Moto x4 specifically. Don't be scared. Just research a lot and follow instructions
