[Q] How to install Lollipop?

So I just bought the XT1068 and I know that the L update is still not released in India so how can I flash it instead of waiting for the OTA? Any step-by-step guides would be helpful because I am quite the noob. My phone is brand new, just removed out of the box so please tell me how to flash the update.

Mate, I'd hold on a bit if I were you . You have to unlock your bootloader to flash these ROMs. Unlocking means losing your warranty (special case in India :crying. And there's also tiny bugs in those ROMs.

It all depends - while I will leave the research up to you, I was able to update without unlocking the bootloader on an xt1064. The trouble is that all the pieces have to fall into place correctly, meaning that you have to have the right update file for your build (and YOUR device - xt1068). My update process was haphazardly documented here. Basically, I started out with a carrier locked (Consumer Cellular) version of the phone, running their specific build. I unlocked the phone's sim lock via online vendor, flashed over the latest factory firmware I could find at the time (21.11.23.titan_retuaws). from there, I installed the specific update to go from 21.11.23 to 22.21.25 (where I am now). but that's the kicker - you need the OTA files that correspond to your exact build(s) and there may be more than one to get you all the way up to current.
Anyway, I did all of this using official, signed OTA files and firmware and more importantly, with a locked bootloader.

NIIIICEEE!!!!!! But the problem here is, we don't have Lollipop OTAs for XT1068/69 to do that.:crying:

CyanogenMod Problem

I flashed my phone with CyanogenMod13, completely not knowing what I was doing. I realized there were a few bugs on CM13 like my camera not working and things like that so I want to go back to stock Marshmallow 6.0.1 so I can have FOTA and a fully functioning phone. I know it was pretty silly of me to actually attempt this without consideration but could anyone help me out on getting back?
I have a Z5 Compact E5823.
Thanks.

Just download flashtool, stock firmware and flash it
btw. It's Xperia Z section, not Z5

Thanks man, sorry about the wrong section.
Will I be able to flash stock rom and receive OTA updates? My bootloader is currently unlocked.
I have already tried flashing before and I am getting random errors each time, with all drivers downloaded properly.
I flashed it with Emma last night and it took me to 5.1.1, and I cant receive any updates, so what am I doing wrong?
I want to go back to stock rom with OTA updates, although CyanogenMod13 was great.

Nope, OTA not working on unlocked bootloader, this can brick your phone

How can I lock my bootloader? Or do you think its recommended I keep the bootloader unlocked?
I just wanted to go back to stock rom for OTA updates thats all.
Many thanks.

Do you have TA partition backup? If no, it's not posible to relock bootloader

I don't even know what that is lol. I should've done research in advance before proceeding to unlock my bootloader. I did make a backup of everything though, I used a tutorial, I used TWRP to backup stuff, or something like that?
Also, is there no way to receive OTA updates now that my bootloader is unlocked? Will flashing stock rom not allow me to receive OTA updates?
Thanks for your ongoing support btw, really stressing me out lol.

Help on XT1254 OTA

Hi guys,
I (and some of my friends) had a problem with XT1254:
1. We updated to 6.0.1 via recovery with update.zip. This process had successfully done.
2. Several felt something wrong with new 6.0.1 system, so they re-updated via recovery again (still the same update.zip). This made the system dead. They could not enter system, except bootloader and recovery. The problem is that source system needs to be Lollipop SU4TL-49 so the re-update process will fail.
3. I did like them and tried to find the solution from old methods:
- tried to downgrade to 5.1;
- tried to flash new 6.0.1 system.img;
- deleted some lines in "updater-script" and tried to sideload via recovery;
but all failed because of "invalid signed image" (for both RSD and fastboot). The partion, boot, kernel have been the newest ones.
4. I tried to downgrade my XT1060 to Kitkat (another mine), and it also failed with flashing system.img. I had to flash the Lollipop's system.img and the problem solved.
Conclusion:
1. Unlock bootloader and flash TWRP will solved the problem for XT1254. The phone could not boot to system so buying a unique key is the only solution (but how to buy?).
2. Wait for the 6.0.1 flash file (xml) then flash via RSD. Several security patches from Verizon may lock the downgrade process.
3. Can some one give other solutions?
Thanks guys!!!!

1. I have never heard of anyone selling bootloader unlock keys for the XT1254. If you want to unlock your bootloader, Sunshine is your only option, and as of right now it will only work on lollipop builds. If your phone is on marshmallow, Sunshine will not work. If your phone cannot boot, it won't work no matter what build you're on.
2. If your phone is bricked and on marshmallow, waiting for the full firmware package is your only option. However, a downgrade to a previous firmware with a locked bootloader isn't, and has never been, possible.

unlock the bootloader and install TWRP BEFORE doing any updates, while still on Lollipop. That is the only safe, logical answer. An unlocked bootloader -- especially with custom recovery -- will let you do lot of things and is more forgiving of mistakes than a locked bootloader.
We keep telling people that and they won't believe us.

Right. Several people who didn't like Lollipop but preferred the original Kitkat "speed", "battery life" or whatever successfully downgraded back to 4.4.4 -- but only AFTER they unlocked their bootloader. Even then you have to make sure you don't flash the old gpt.bin in ADB, but downgrading is possible with an UNlocked bootloader.
Even when flashing XT1250 firmware over XT1254 or vice versa, it CAN be done with a locked bootloader, but if you mess something up you are in big trouble. UNlocked bootloader? Just do it again, correcting your mistake the next time.

There was a guy on some website who was selling some Verizon keys a long time ago, known as "the Chinaman". He disappeared.

and another thread discussing same guy:
http://forum.xda-developers.com/moto-x/general/4-1-vzw-att-moto-maker-bootloader-t2680651
The process seems to involve sending approximately $45 to a Chinese middle-man via eBay and another website, along with your IMEI and cell phone number, and you will receive an unlock code.
It seems like this is all one guy handling this process. Turnaround time seems to be 24-48 hours beginning to end.

Theory was that someone with access to Motorola's engineering software had a side business going. You know they unlock their bootloaders for testing and such. Someone with access to that software could make some money if they made sure they covered their tracks.
Also people who visited China were able to buy unlocked bootloader Droid Turbos well before Sunshine was released. One guy posted in this forum. In that case, it was probably pilfering some phones from the factory -- but again with unlocked bootloaders. So, there is some software out there somewhere, just kept under wraps.

Haha the Chinaman? Really? Sounds like an evil arms dealer from a 90's action movie. Man, if only the magic official bootloader unlocking software was leaked. That would be like Christmas times infinity.

I updated my post to include XDA links. I can't find any examples of Droid Turbos being unlocked via this eBay "purchase" only other Verizon phones, but there are the legitimate reports of unlocked Droid Turbos for sale in China in the year prior to Sunshine being released November 2015. One guy even posted on here because he was trying to install CM12.1 at the time on his BOOTLOADER UNLOCKED Droid Turbo he had purchased in China.
Note the Chinese middleman guy was charging $45 for bootloader unlock at the time, and Sunshine only charges $25.

xml flash file is the last solution =))

@ChazzMatt: I think it's impossible to cross flash 1250 to 1254, but 1254 can flash to 1250

Doesn anybody know how much does usually takes for Verzion ( or whoever does it ) to release xml sbf firmware file? And do they release every? I need latest MCG24 or at least system file (s) is enough.
I have everything except system files, if anybody can provide system files or knows hot to convert ones from ota , I can make complete fastboot xml zip.
EDIT: System from OTA is not enough. If somebody can provide system / backup from MCG24 phone, I might be able to make it.

Can you give little more info on this. Changed cid? Unlocked bootloader? Maybe we can use x1250 xml fastboot files until they release Marshmallow fastboot. I need one for backup , I know I'll brick the phone sooner or later , as guys above did lol..

Yes, unlocked bootloader and you don't flash the XT1254 bootloader. This was before Sunshine, and he converted XT1250 to XT1254 with unlocked bootloader.
We chatted over a few days, while he tried to find an XT1250, ordered one, then it arrived. Then he flashed the Verizon firmware. Here's the relevant portion of what he wrote:
Flashed the Verizon radio and 5.1 FW (firmware)
The only problem I have right now is upload speeds are super slow.
gonna try wiping the radio and re-writing the radio
Click to expand...
Click to collapse
I then asked him a couple of questions and he answered this:
Yes I flashed the Verizon Radio to the device
not the bootloader image, for obvious reasons
I wanted 5.1, so I didn't test until I had the VZW 5.1 with my SIM card
I'm going to try an reflash soon, and then get a new SIM just in case
I hope Verizon doesn't give me any trouble getting a new SIM at my local store

I didn't hear from him anymore after that, so guess everything turned out OK. This in August 2015, was about a month after 5.1 was released for the Droid Turbo XT1254 (XT1250 was still on 4.4.4) but before Sunshine released their bootloader unlock for the XT1254 in November 2015.

Yeah but we're talking about vice-versa here, flashing xt1250 Firmware to xt1254 .
Flashing xt1254 firmware to xt1250 with unlocked bootloader doesn't seem like a big deal, it should be possible anyway..

That's been done, too. I didn't know that was the question.
One guy didn't want Verizon bloatware and his solution was to flash the "pure" Motorola firmware from the XT1250 over his XT1254.
Yes, he had unlocked bootloader and could have just uninstalled the bloatware. I'm not saying it was logical, I'm just telling you what he did.
So there's no question these two phones are exactly the same device, with exactly the same FCC ID.
The issue is the XT1250/XT1254 being flashed needs to the other needs an unlocked bootloader. And you can't downgrade (gpt.bin) when you flash.
So, for the purposes of this thread that information doesn't help you, if your XT1254 bootloader isn't unlocked.

How do I remove TWRP?

I have the Amazon variant of the 16gb Blu R1 HD. I installed TWRP with the Unlock Tool for all versions tutorial (https://forum.xda-developers.com/r1-hd/how-to/unlock-tool-t3561333) on this forum and also removed ads. I would like to get back to the stock bootloader and image for my phone, to receive OTA updates and have the original experience, I am alright with having the ads back, I would just like my phone the exact same way it came from the factory. I know the updated roms will be ported and etc. I would like it back as the way it came, ads and all. (I'm aware I will not get my warranty back.) I read this tutorial: https://forum.xda-developers.com/r1-hd/how-to/firmware-amazon-blu-r1-hd-t3428197 but I'm not sure if it will work with TWRP, I'm confused whether or not fastboot works with TWRP installed. I would also like the bootloader to be locked again as well, I'm not sure whether or not flashing stock firmware would do this. If anyone could help explain this to me or point me to a tutorial somewhere it would be appreciated. I searched through the forum for similar entries, I didn't find anything for the R1 HD specifically, and entries for other phones on removing twrp/flashing stock recovery didn't seem to make sense. I apologize if I missed another post concerning this issue. Thanks.

this is not quite a normal request.
any and all changes done to your phone are done at your own risk, no guarantee that the process will be "safe". and no guarantee the end result will be as expected.
I can upload stock system, boot, and recovery images.
download them, unzip the file. put the 3 .img files to the phone.
reboot phone to twrp.
select install, browse to the folder you loaded files to, you should not see the file yet. Select flash image in lower part of screen. Now select system.img, on next screen select system and swipe to confirm.
when done do same for boot.img to boot
then recovery to recovery
when all three are done do a wipe(factory reset)
this should bring you back to prime v6.1
be advised that re-locking the boot loader has potential of bricking the pone so it is not advised to do it.
also on all the early versions there are reports that after ota update with unlocked bootloader it caused a bootloop most times it was recoverable by performing "oem unlock" again.
once booted to v6.1 I suspect there will be proper update notice. but if not here is a list of the official update download links.

@Ladyslayer
Can you tell your experience to restore phone to original condition?
Were you able to avoid bootlop and relock bootloader?
After development ceased I also wanted to restore my phone to original factory state but following restore guides leaves my phone in bootloop. BTW in @rootjunky thread there are all original 6.1 partitions that is if you feel brave and lucky, myself am scared to flash these.
@mrmazak
I think warnings in guides are misleading. Most people are aware of risks to flash modified firmware but they are not aware there is no way to restore phone to original firmware once they modify phone.
No intention to criticize you. Thank you for your effort to keep modified firmwares up to date. Looks like you are only one not giving up

well you can go back to locked but it is tricky. Think of it like this.
unlocking , allows anything you put on phone to try and load.
when you re-lock it only properly signed images are allowed to load.
so you can potentially lock yourself out of allowing phone to boot up, so the warning is more relevant when trying to go back to a locked state.

Sorry guys I have yet to try it out, I don't have a lot of time and am a little nervous to bite the bullet. @kfn, did you follow the guidelines in the above post to restore to original condition or a different set of instructions from somewhere else? Btw any suggestions on how to back up pretty much everything? Sorry Noob here obviously.

I flashed 3 original partitions system, boot, recovery as described by mrmazak then I took OTA update. After OTA update phone was in bootloop. I did not bother with backup because I do not have important data on phone.

Which version update was it?
I can't be certain about the 8.4 or 21 updates, but older ones when that happened you needed to boot into fastboot mode and do oem unlock again.

https://forum.xda-developers.com/r1-hd/how-to/guide-convert-to-prime-rollback-ota-t3432499
I downloaded from his website, I believe they were 6.1 versions.
At the time 7.4.2 was current firmware, I think phone rebooted few times taking OTA updates. And yes 'fastboot oem unlock' trick worked to get rid off bootloop.
I presume fastboot oem lock might relock bootlader but got scared to try it because of bootloop.

Do you still have the phone? Have you done the OTA updates since then with an unlocked bootloader?

did not try another OTA, put back modified ROM and disabled OTA.
Here post #312 with similar unanswered question about relocking bootloader, it is unclear for me if another OTA would properly relock it without bricking.

@mrmazak, do you know whether or not installing OTA updates would relock the bootloader? Wouldn't it be possible to do fastboot OEM lock and then do OTA updates without the risk of a bootloop? Noob question: does locking the bootloader reset the phone as well? I seem to have read something about this but I can't remember.

The update has not relocked the bootloader before.
Let me clearify a little.
There are three things I know that get changed when doing OEM unlock
1. Unlock status changed to a yes
2. Secure status changed to a no
3. Warranty status changes to no
After an ota #2 above( secure ) changes back to yes
This conflict is what makes the boot loop. As far as I know.
I do not know what it does when put back to lock and you do an ota.
I think each time you change, lock or unlock it needs to be reset the phone.

Wouldn't it change number one to a no, and two to a yes? What is the likelihood of a bootloop out bricking the phone if I re-lock the bootloader or do an OTA with the bootloader relocked? Isn't that the same as doing a normal OTA with a phone that had no changes from factory version, just the warranty status is a no and that's it?

I do not know for sure. And there fore cannot recommend to do it. In the event something goes wrong and bootloader is locked, you cannot use fastboot to flash a repair, there fore MY opinion is the same "DO NOT relock bootloader". If something goes wrong it will be a brick.
Run stock version un modified all you want but if you unlocked I do not think you should relock. My opinion, do as you want.

How to Root LG G6 H872 on Android Oreo

Hi everyone! I recently bought a LG G6 H872, which still has 10e installed. After crawling the forums for a bit, here's the sequence of things I wanted to do to it:
1.) Update to 8.0 Oreo via OTA.
2.) Unlock bootloader
3.) Root and TWRP using this: https://forum.xda-developers.com/tmobile-g6/how-to/root-h872-to-including-11g-t3775518
4.) Magisk
Is the latest Oreo update the 20a version that is mentioned in the thread or should I manually update it to something older. I saw that there was anti-rollback so I don't want to update too far. Also, if there is ever another OTA, how does one update the rooted phone?
Edit: I wrote up some steps if it helps you on this post: https://forum.xda-developers.com/showpost.php?p=77513501&postcount=4

I do not believe there is currently a way to root the T-Mobile versions.

That is not correct, see: https://forum.xda-developers.com/tmobile-g6/how-to/root-h872-to-including-11g-t3775518

For future people who come across this thread, here are the steps I took to root this phone:
1.) Factory reset and then update device via OTA incrementally until 20a (which is Android Oreo 8.0)
2.) unlock bootloader: https://www.youtube.com/watch?v=EpaW0-8-QKY
3.) root device: https://forum.xda-developers.com/tmobile-g6/how-to/root-h872-to-including-11g-t3775518
Note: there is a video tutorial here: https://www.youtube.com/watch?v=-z4CWLikPcI&t=821s. The first steps of flashing the laf partition are very useful to watch before attempting
4.) Factory reset in TWRP
5.) Reset after encryption error, then wipe with TWRP. May give mount error.
6.) Boot into Android Oreo. Device is not yet rooted at this point.
6.) Flash MAGISK via TWRP (SD card or ADB push) ]. Ignore the mount error. Reboot.
7.) Device is rooted! :good:

That's interesting
Without getting into an issue those steps look slightly different in order than the original process.
Or I'm a dumbass and somehow got it out of order. Seems ok now though.

Hello there!
I want to ask if it's the same to do the steps with 20e ?

Curious as well if this works with the latest update.

This is an already rooted version of the latest update. I've downloaded but haven't flashed it yet, but the op is good and I've never had an issue with his work.

I succeeded in completing the process.
Permanent unlock from Tom via app.
Unlocked bootloader.
Twrp installed to recovery, can boot to recovery via low volume/power button combo.
Magisk installed.
20a working nicely.
I'm getting requests from Tmo to update from 20a to 20d. Is this recommended? Will twrp, root, unlock, etc. be lost?

I am glad to see that the bootloader gets unlocked easily. @alliance1975 how did you go from Unlocked bootloader step to Twrp installed step? That is the big one I think.
There is a good TWRP available, but we can't install it because the phone lacks fastboot commands. Is there a way to install TWRP? Or is it really that the only method is the rather risky runningnak3d method?

I used the procedure summarized in step 3. I agree it is risky, well, the riskiest root & twrp I've ever tried. I neglected to say I only read instructions, the dev who actually came up with the plan deserves all the credit.

When I try to oem unlock nothing happens. What can I do? I have followed all other instructions.

Yeah I got my bootloader unlocked

Any info on this? Will updating from 20a mess up the phone (root, etc...)?
