Quick question, do I have to downgrade from 1.4 or am I good to go from 1.4 to 1.7?
[EVO 4G Android Development] jelive:
No...straight to 1.7

Jim
[EVO 4G Android Development] midnightmaraude:
I just did it from 1.40 No issues. No idea what this does but I like to stay current. :) Thanks guys

Are these good speeds?

After the PRI I get 2.24Mb/s down and .43 Mb/s up.

not sure what it was before the PRI update.
[EVO 4G Android Development] stanglifemike:
Cool bro, thanks for the info
[EVO 4G Android Development] intheb0x:
okay here's the deal, I loved 1.34.

I followed the PRI hype the first time around and got my phone to ota to 1.40.

My speeds were then cut in half and I went through hell trying to get 1.34 back on my evo.

When if i did get back to 1.34 my speeds were back to normal .

i would also like to know more about where to file originated from.

I did the update anyways and my speeds seem to be faster.

Time will tell, is just personally like to know where it came from and what the significant changes are.

Thanks all, I used the recovery file.

I'm rooted via simple root using AC ROMS 2.5.
[EVO 4G Android Development] rutter9:
went from 1.34 to 1.77 using flashable zip. no problems.
[EVO 4G Android Development] Award Tour:
Quick note, after updating 4G was slower but roughly the same. 3G was absolutely horrible, went from a average of 1.03 Mbps to under 0.5 Mps. Did 9 tests for each 4G/3G on both PRI's (same server and disconnecting/reconnecting for each test).

PS: On a unrelated note, I forgot how damn ugly and horrible stock Sense is.
[EVO 4G Android Development] TorxT3D:
something about this pri i dont like.. im think im going to flash back to 1.34

and i'll just check the software update screen for any official releases...
[EVO 4G Android Development] Award Tour:
I'm sure that this is largely dependent on location but if you live in Brooklyn/NYC, avoid this update because this thing KILLED my 3G, i'm getting ~ .3 Mbps now.
[EVO 4G Android Development] intheb0x:
So your speeds are slow now after going back to 1.34 as well?
[EVO 4G Android Development] Award Tour:
I haven't gone back yet. I'm probably going to stick with 1.77 and check back later tonight in case it's a peak issue. I have a iPhone 4 w/ ATT/HSPA+ so I can live with a slow EVO for now. I'll post back if it changes later, and if it doesn't, I'll downgrade and post whether that changes me back.
[EVO 4G Android Development] intheb0x:
please keep us posted ,i have a feeling that if you downgrade your speed will b back to normal .

so if i was you i would downgrade to try that .
[EVO 4G Android Development] Award Tour:
Yeah, I'm not sweating it, I'm sure it'll switch back. I'm just leaving work now and don't have time to downgrade and test.
[EVO 4G Android Development] asrebel:
My 1.77 experience

I'm running CM6.0; Update was fast and easy.

Verified PRI version and that 4g was still working by flashing an old Fresh ROM. A-ok there! (but yes, I was leery because I was hit with the 4G authentication issue before) Did some preliminary benchmarks; I didn't feel like there were really any significant differences (for me...in Idaho). I'm sure your results may vary and I appreciate everyone posting their results.

I did notice one negative feature. I ride the elevator to work every day. While I'm in the elevator, I lose 3g service. Once I would step off the elevator it would sometimes take a minute or two for my 3g signal to come back. Now it consistently takes up to 15-20 minutes. I tend to believe it's related to this update because I've never had any issues like this before, and this is the only change I've made.

Curious if anyone else has noticed this issue. Obviously it could be a combination of my location + the update, but just thought I'd ask.

Anyone know if they are going to make a flashable version of 1.71?
[EVO 4G Android Development] exdroid1:
Thanks for the file. After a few hours of testing, I realize that I need 1.34 back on my phone. Honolulu, HI
[EVO 4G Android Development] Award Tour:
Another update:

I'm in a coffee shop now doing work after work (I know, sad). I updated the profile which I forgot to do before and I'm not sure whether it's the new location, time, or profile update, but I'm getting my normal speeds of about 1.5 Mbps again. I'm even getting a faint 4G signal in here which I never used to get, but I can't really say for certain that it's attributed to the new PRI since 4G is going official in NYC soon plus I've been using CM6 for a long while now.
[EVO 4G Android Development] bigbiff:
OK I restored a nandroid with Amon RA 1.8 recovery with a good wimax image and now I just get Scanning like I used to get. I will post back tomorrow if I have successful 4g connectivity. I flashed the PRI 1.7 and still says Scanning. Before it would fail to start.

So the moral is: nandroid with Amon RA 1.8 and backup that nandroid somewhere safe, because you never know if the wimax partition will take a crap. I have no idea what caused the issue.
[EVO 4G Android Development] toneman1984:
I updated my profile but I didn't reboot after that. Also I used the recovery flashable version. 3g stopped working. I may try again and update profile, prl, and reboot after that.
[EVO 4G Android Development] GeneralSpecific:
Thanks devs!

After several tests, I could get no higher than 7mbps with 1.34. I flashed the 1.77 over today, and with the phone in the exact same place, my speeds increased significantly. Check my sig!
[EVO 4G Android Development] BmoreBadBoy:
I used the recovery flashable version with no problems. 3G is a bit faster. 4G signal is definitely stronger. Calls seem to be clearer. Baltimore. Thanks for the update!

Edit: I forgot to mention, just got an brand new Evo in the mail today from Best Buy stock room. It has PRI Version 1.71_003
[EVO 4G Android Development] bainster:
I posted before that I lost WiFi after the PRI update, but after further testing reveals I did not lose the functionality. Actually WiFi still works, but not with my router. My router is a dlink dir-655, but after the update, my evo connects and then does nothing. Really strange as i plugged in a spare router I have, and it worked fine. Nothing has changed on the router, and this started after the update. Anyone have any ideas? Thanks.
[EVO 4G Android Development] aph:
I had the same experience in midtown Manhattan (2.2mbps -> 0.5mbps), but the speeds mostly came back after a while. Give it some more data points over a few days before you jump to any conclusions.
[EVO 4G Android Development] tomh1979:
My 4g has gotten better, at work I can actually get it now, and right here while I'm on the crapper swyping this message, and downloading a rom, lol.
[EVO 4G Android Development] cabbieBot:
reached my phones record high by getting 8033 kbps download. This PRI is the truth.
[EVO 4G Android Development] Freelancerx:
can definitely confirm a better 4g signal for me
[EVO 4G Android Development] intheb0x:
LOL.

anyways,

i WISH WISH WISH i had 4G in my area to test before and afters, but i can say for sure this PRL is the REAL DEAL. my 3G speeds are faster easily, at my house sometimes the speed increase from before is significant...

ill say again, the last time i updated following the hype from 1.34 to 1.40, my speeds fell HARD, kinda like how it is with the ppl in Manhattan. so i downgraded and speeds were back to normal.

i upgraded this file while driving LOL, downloaded, nandroid backup, recovery flashed it, and all is good.
[EVO 4G Android Development] Tiffany84:
Should I update my profile with this or no?
[EVO 4G Android Development] intheb0x:
i didnt after i updated and i noticed faster speeds.

but hours later i did anyways and nothing changed.

so u can if it makes u feel better.
[EVO 4G Android Development] edufur:
I updated the NV and PRI versions via flash and it seemed my 3G speed went down a little... but even more bothersome is that my home WiFi went down by 2 Mbit. from 7 to 5. This is very concerning.

Also, I am wondering how the zip flash process was supposed to look... each time i did the flash, it required reboot and after reboot it would say Formatting Cache at the bottom but never go past that. Is this normal?
[EVO 4G Android Development] joeykrim:
Added the latest radio - 2.15.00.09.01
[EVO 4G Android Development] martijua:
flashing the new radio now, thanks.
[EVO 4G Android Development] GadgetMonger:
Yup... Thats the way it works. When it says formatting cache and the option to reboot system comes up (formatting cache will remain on the bottom of your screen) youre supposed to select to reboot and youre done.
[EVO 4G Android Development] bigbiff:
OK, I am in the reston virginia area and 4g works again. So restoring the wimax partition using amon ra 1.8 brought it back. My symptoms were not being able to start 4g at all.

So if you have 4g currently working make sure to nandroid with amon ra 1.8 recovery and store the nandroid somewhere safe. (at least the 12 mb wimax.img file)
[EVO 4G Android Development] cadbomb:
Where did this come from? I didn't see it as part of the new update...
[EVO 4G Android Development] joeykrim:
good question. OP has been updated!

PRI and Radio are both in the new OTA update!

[EVO 4G Android Development] jdeloach:
So if we have already upgraded to pri 1.77, then we don't need this pri upgrade? Or is it different somehow?
[EVO 4G Android Development] joeykrim:
good question. i've updated the thread title.

short answer no, this comes in and from the OTA 3.29.651.5.
[EVO 4G Android Development] m4rk0358:
What is the rcdata file for? Do I need to update that and the radio?
[EVO 4G Android Development] JvIo55iBl3r:
Had problem here(Dallas, TX).

HBoot PRI 1.77_003 after flashing the latest radio.

Didnt see much difference on 3G, but having problem to turn on 4G, which usually is no problem at all. keeping turn on --> scanning --> turn off.

Anyone can help?
[EVO 4G Android Development] Rydah:
Hey joey, I see that the title has the right info, but when you download the latest radio, it says .7. Instead of .1 but when flashed says .1

Just a heads up about the typo.
[EVO 4G Android Development] ty080279:
i updated pri 1.77_003 and radio 2.15.00.09.01 now i get 4g in my house...
[EVO 4G Android Development] joeykrim:

Original Post says downgrade back to 1.34?

Is this old information or are we really supposed to flash new 2.15.00.09.01 radio and 1.77 PRI then re flash 1.34 PRI? that makes no sense...
[EVO 4G Android Development] DaWhip:
The 1.34 is only posted in case 1.77 has negative effect for you, that way you can go back. Only if 1.77 sucks in your area as some have reported.
[EVO 4G Android Development] ty080279:
had this issue with other roms....for me wiping data/cache and dalvik x2 then nand restore or new install resolved issue
[EVO 4G Android Development] Rattor:
I believe the downgrade is provided for those who have problems with 1.77, or if you want to go back for some reason.

I had a quick question. I've been away from XDA for a bit. What exactly is s-off?
[EVO 4G Android Development] JvIo55iBl3r:

Im having troubles with the PRI part. I flashed the radio and that worked perfectly, then i went on to push the PRI and it pushed successfully but when i went to the bootloader in the phone, it went to checking, checked it, and then stopped. Same thing when i copied it over to the SD Card through windows. Any suggestions as to whats going on?
[EVO 4G Android Development] Chaotic0589:
Yep, just tried both the pushable on and Calkulin flashable and no results
[EVO 4G Android Development] newbapotamous:

So i put these on my sd card and then went into recovery mode and ran them both from there. the radio seemed to work, but the pri didn't. it says i'm running Basband 2.15.00.09.01 and PRI Version 1.40_003

I ran unrEVOked 3 days ago, then tried to get the new HTC fix...it didn't go so well so i got the deodexed version from here and ran that...it seems to be running now, but i'm not sure about the PRI thing

I'm also running this from a mac. If anybody can help, that'd be great.

[EVO 4G Android Development] Chaotic0589:
What did you do to get it working newbapotamous?
[EVO 4G Android Development] scooter185:
the problem has been getting the RCdata.img (and NV.img with it) to flash. Clearly this method flashes the RCdata (Radio_Cust). The visual updates where a hex edit hack.
[EVO 4G Android Development] ckombo:
Thanks! Works perfect.
[EVO 4G Android Development] Calkulin:
That was because no other rcdata.img was released until this one
[EVO 4G Android Development] joeykrim:
they updated the pri version through hex editing the nv.img.

this is the rcdata.img which we haven't had since the Eng RUU which came with rcdata.img for PRI version 1.34.

updated OP.
[EVO 4G Android Development] Calkulin:
Actually it was the rcdata.img that I hex edited to change the version #
[EVO 4G Android Development] tomh1979:
updated me to 1.77, thanks to those involved in getting this.
[EVO 4G Android Development] zikronix:
im still skeptical because you got people out there running around with 1.34 and 1.40 which we know are good then reports of 1.71 and now all the sudden 1.77 ?????

this from the same team that borked a whole bunch of peoples 4g....I think i wait and see.

I was impressed with unrevoked's s-off and ill give them that. the real test is if I hard reset facotry defaults wipe the phone will i go back to 1.34 as thats whats included in the eng hboot. I went from 1.34 to 1.40 via ota and there have been some that said when they hard reset they were back on 1.34

then you have this

and this file is....exactly that an rcdata.img, how do we know this didnt happen?
[EVO 4G Android Development] Noxious Ninja:
So I guess the question is, what is the source of this rcdata.img? Is it something that could occur "in the wild"? Or, if I had to unroot and take my phone in, would this be a dead giveaway that I had been rooted?

Thank you Joeykrim! Working on EViO2
[EVO 4G Android Development] GadgetMonger:
Yeah... when did we make the jump from 1.71 to 1.77?
[EVO 4G Android Development] litlepyro:
So where was this one pulled from?
[EVO 4G Android Development] Calkulin:
I did a file comparison of the original 1.34 PRI and this one because I found it odd that they both had the same file size, so I wanted to make sure it wasn't a hex edit like I had done before and there are more differences than just the version #, so this update does seem to be authentic.
[EVO 4G Android Development] red man:
Works on fresh thanks
[EVO 4G Android Development] GadgetMonger:
So you think it came from Sprint? A leak?
[EVO 4G Android Development] m03sizlak:
Allow me to be the first to say: WOOOOOOOOOOOOOOOOOOOOOOOOOOOOOT

Now, please do explain where the rcdata.img file came from, and how it was packaged into an update, and whether or not the 1.77 NVRAM was updated as well.

Thanks.
[EVO 4G Android Development] zikronix:
i also want to know how we went from 1.71 to 1.77
[EVO 4G Android Development] bloodrain954:
Why does it matter?
[EVO 4G Android Development] AHrubik:
Thanks! :D

Is there a flashable version of the 1.4 PRI? I've updated my radio, tried 1.7 and flashed back to 1.3 PRI's.. all have pretty similar (and poor) speeds for me.. just wondering if i could try 1.4 easily to compare all 3.
[EVO 4G Android Development] newbapotamous:
My Fix & Assessment

Actually, I went to the Recovery version of the PRI by Calkulin and got it to work. I should have read clearly on the first page rather than act in haste.

BTW, one thing I've noticed since updating the Radio, PRI, and OTA - DeOdexed, my battery is staying substantially hotter 11.6 degrees to be exact. Prior to the updates, it ran at 75-85 F (while limiting the CPU to 499 MHz with Set CPU) but is now chillin at 96.6 F (given the same conditions).

Not a big deal, but I'm assuming it has to do with the faster FPS. That or I totally effed up the batter in the process of updating.

Note:

I had to run the DeOdexed version of the OTA - due to removing lots of apps via rooting - and had a lot of choking at the "HTC EVO 4G" and "Sprint 4G" screens and had to pull the battery a couple of times (initially because I forgot to wipe the chache & delvek or whatchamacallit). This is also a likely cause of the increased battery temp.

No flashable 1.40 update
[EVO 4G Android Development] SITH16:
Would it be a problem for me to flash this radio on to my burnt rom 1.1? Or should I wait till I upgrade to the new OTA update?
[EVO 4G Android Development] joeykrim:
not familiar with the ROM, but more than likely there won't be any issues updating the radio ahead of the ROM.

the safest method is to make sure you have a copy of your current radio, which you could revert back to in case there are any conflicts. also making a nandroid of your current ROM will also help, just to be safe.
[EVO 4G Android Development] JvIo55iBl3r:

[EVO 4G Android Development] uclajw1:
Running Fresh 3.2 with Net .8 kernal. Flashed new radio and PRI without any problems. 3G speeds seem to have improved by about 300-400 kbit/sec. 4g and roaming still works. Haven't had a chance to test out 4g speed yet on new pri and radio. I was really happy with the result until I found out that my friend's stock Evo that she just got last week is pulling an average of 1.5Mbit/sec download on 3G. I tested her phone and mine side by side using the same server on Speedtest. What gives? She still has pri 1.4 with 2.15.00.07.28 base band and build is 3.26.651.6 CL218634 release-keys.

[EVO 4G Android Development] darth1289:
I see an improvement because of this upgrade

Live North of Austin. Have rooted stock rom 3.26.651.6. We have 4G in our area.

Here are my observations since upgrading. All tests were conducted indoors. I used the recovery image for the PRI update.

1) My speed test on my home wi-fi has increased from around download speeds of 5Mbps to 12Mbps. I could never understand why my EVO was giving really low speeds, when my Ipod touch use to give much higher (12Mbps ) for my home wireless. Now they are very close, Ipod is still faster in speed test though

2) I never got more than 500kbps d/l on 3G. Now they are between 1.5Mbps to 2Mbps, uploads are around 600kbps.

3) 4G speed did not change d/l remains around 5Mbps and upload between 800kbps and 1Mbps.
[EVO 4G Android Development] aph:
Can someone make a thread or point me to a thread that shows a working method to get back to 1.40? I've tried the following so far:

1. ##786#

2. EPST Restore and ##786#

3. Flashing Froyo 2.2 stock at ##786#

4. Flashing 1.34 and ##786#

The last attempt landed me at a previous PRL too, so I had to manually go back to 60670 which is no cakewalk either.

I noticed worse battery life as well but I can't be sure it's not from increased use while testing. I probaby have the same ebay charger you use so I'm going to completely recharge the original battery that came with the phone and then stick it in and try not to use the phone too much. With the original battery and light use I could usually get 2 days out of it. I'll post updates once I'm done.
[EVO 4G Android Development] misterzeno:

[EVO 4G Android Development] kellte2:
The stock battery life sucks because Perflock can't be disabled on that kernel by SetCPU. I flashed Netarchy's recently official (read: stable) 4.1.9.1 kernel and man is it a lot better than the HTC kernel. The frame rate is more stable and the battery life is great - not to mention the fact that Perflock is disabled by default.
